    [0002] The overall appearance design and function design of an existing side water inlet valve are performed according to the requirements of product function, water route design, size of common parts such as water stop pad, water inlet joint, and the like. In order to meet the uniform wall thickness requirements of injection molded parts, the existing side water inlet valve usually has a rigid structural feature in appearance, and the space for appearance beautifying design is limited, which leads to certain limitations in the appearance design of the side water inlet valve, thereby affecting the beauty of the product. Moreover, the appearance structure of the existing side water inlet valve is complicated and the associative perception is poor.

    [0003] Documents US 1,321,673 and US 4,108,202 disclose known water inlet valves comprising a water inlet body provided with a water inlet channel, a water outlet pipe provided with a water outlet channel, and an outer sleeve pipe arranged so that a water flow channel is formed between the outer wall of the water inlet body and the inner wall of the outer sleeve pipe, through which the water inlet channel is in communication with the water outlet channel. On the other hand, functional improvements of these known valve are possible.

    SUMMARY OF THE INVENTION



    [0004] An object of the invention is to provide a side water inlet valve and a flush toilet, which overcome defects of the prior art, and technical solutions adopted by the invention to solve technical problems thereof are as follows.

    [0005] According to one aspect of the application, a side water inlet valve is provided, comprising a water inlet body provided with a water inlet channel, and a water outlet pipe provided with a water outlet channel, wherein, an outer sleeve pipe in communication with the water outlet pipe is fixed at the end of the water outlet pipe, and the water inlet body is sleeve coupled in the outer sleeve pipe from an opening at one end of the outer sleeve pipe, such that the water inlet body and the outer sleeve pipe are sleeve coupled and engaged. The water inlet body and the outer sleeve pipe are detachable, and a water flow channel is formed between the outer wall of the water inlet body and the inner wall of the outer sleeve pipe, through which the water inlet channel is in communication with the water outlet channel.

    [0006] Alternatively, the water outlet pipe is longitudinally disposed to form a longitudinal water outlet channel. The outer sleeve pipe is laterally fixed to the top end of the water outlet pipe, and a water outlet of the water flow channel is disposed on the side wall of the outer sleeve pipe. The top end of the water outlet pipe is correspondingly disposed at the water outlet of the water flow channel, such that the water outlet channel is in communication with the water outlet of the water flow channel. The water inlet body is laterally sleeve coupled into the outer sleeve pipe to form a lateral water inlet channel. A circumferential water flow channel is formed between the outer wall of the inlet water body and the inner wall of the outer sleeve pipe, and the water inlet channel, the water flow channel and the water outlet channel form a T-shaped water passage.

    [0007] Alternatively, two seal grooves are arranged at the outer wall of the water inlet body circumferentially at intervals, and are respectively placed with a seal ring. The two seal rings are sealingly disposed between the outer wall of the water inlet body and the inner wall of the outer sleeve pipe, and define the axial range of the water flow channel.

    Compared with the related art, the technical solution has the advantages as follows:
    1. 1. By fixedly arranging an outer sleeve pipe in communication with the water outlet pipe at the end of the water outlet pipe, the water inlet body is sleeve coupled in the outer sleeve pipe from an opening at one end of the outer sleeve pipe, such that the water inlet body and the outer sleeve pipe are sleeve coupled and engaged. The water inlet body and the outer sleeve pipe are detachable, and the water inlet channel of the water inlet body is in communication with the water outlet channel of the water outlet pipe. As such, the outer sleeve pipe is adopted to wrap the water inlet body, such that the structure and appearance of the product are greatly adjusted compared with the existing side water inlet valve, and the appearance of the product is more beautiful, novel and holistic; moreover, some parts of the water inlet body of the existing side water inlet valve may be omitted by the use of the outer sleeve pipe, such that the product is simple in structure and good in assembly manufacturability, thereby achieving the effect of reducing the cost.
    2. 2. A water flow channel is formed between the outer wall of the water inlet body and the inner wall of the outer sleeve pipe, through which the water inlet channel is in communication with the water outlet channel. The advantage of such arrangement is that the water route structure in the water inlet body of the existing side water inlet valve can be greatly simplified, and the gap between the outer wall of the water inlet body and the inner wall of the outer sleeve pipe is fully utilized, such that the water route design is more ingenious, simple and novel.
    3. 3. By sealingly dispose two seal rings between the outer wall of the water inlet body and the inner wall of the outer sleeve pipe to define the axial range of the water flow channel, the structure is simple and easy to install.
    4. 4. The water inlet body further comprises a steering hole for steering the water flow of the water inlet channel, and the anti-siphon seat comprises a seat body which is abutted against the upper end of the steering hole, and two side walls extending downward and longitudinally and movably sleeve coupled outside the steering hole.

    DETAILED DESCRIPTION OF THE EMBODIMENTS



    [0016] The technical solution of the invention will be further described in detail below through the accompanying drawings and embodiments.

    [0017] Embodiment 1:

    [0018] As shown in FIGs. 1 to 7 , a side water inlet valve fixed in a water tank body 1 is provided, comprising: a water inlet body 10 provided with a water inlet channel 11, and a water outlet pipe 20 provided with a water outlet channel 21, wherein, an outer sleeve pipe 30 in communication with the water outlet pipe 20 is fixed at the end of the water outlet pipe 20, and the water inlet body 10 is sleeve coupled into the outer sleeve pipe 30 from an opening at one end of the outer sleeve pipe 30, such that the water inlet body 10 and the outer sleeve pipe 30 are sleeve coupled and engaged. The water inlet body 10 and the outer sleeve pipe 30 are detachable, and the water inlet channel 11 of the water inlet body 10 is in communication with the water outlet channel 21 of the water outlet pipe 20. The water inlet body 10 further comprises a steering hole 19 for steering the water flow of the water inlet channel 11.

    [0019] In the embodiment, a water flow channel 40 is formed between the outer wall of the water inlet body 10 and the inner wall of the outer sleeve pipe 30, through which the water inlet channel 11 is in communication with the water outlet channel 21. As such, the water route structure in the water inlet body 10 of the existing side water inlet valve can be greatly simplified, and the gap between the outer wall of the water inlet body 10 and the inner wall of the outer sleeve pipe 30 is fully utilized, such that the water route design is more ingenious, simple and novel. Of course, the embodiment may also be such that the inside of the water inlet body 10 itself may be provided with a water flow channel 40 in communication with the water outlet channel 21, which can also achieve the purpose of communicating the water inlet channel 11 with the water outlet channel 21 and no more details will be made here.

    [0020] In the embodiment, the water outlet pipe 20 is longitudinally disposed to form a longitudinal water outlet channel 21, and the outer sleeve pipe 30 is laterally fixed to the top end of the water outlet pipe 20, and a water outlet 41 of the water flow channel 40 is disposed at the side wall of the outer sleeve pipe 30. Specifically, the water outlet 41 is located at a middle position on the bottom side wall of the outer sleeve pipe 30, and the top end of the water outlet pipe 20 is correspondingly disposed at the water outlet 41 of the water flow channel 40 to communicate the water outlet channel 21 with the water outlet 41 of the water flow channel 40. The water inlet body 10 is laterally sleeve coupled into the outer sleeve pipe 30 to form a lateral water inlet channel 11. A circumferential water flow channel 40 is formed between the outer wall of the water inlet body 10 and the inner wall of the outer sleeve pipe 30. Specifically, the circumferential water flow channel 40 is designed as a full circumferential channel. Of course, if only a water flow channel 40 of half circumference is formed between the outer wall of the water inlet body 10 and the inner wall of the outer sleeve pipe 30, it can also effectively communicate the water inlet channel 11 with the water outlet channel 21, while the other half circumference between the outer wall of the water inlet body 10 and the inner wall of the outer sleeve pipe 30 can be designed as a water replenishing channel communicated with a water replenishing pipe for replenishing water to the flush toilet water seal. In the embodiment, the water inlet channel 11, the water flow channel 40 and the water outlet channel 21 form a T-shaped water passage.

    [0021] In the embodiment, two seal grooves 12 are disposed at the outer wall of the water inlet body 10 circumferentially at intervals, and are respectively placed with a seal ring 14. The two seal rings 14 are sealingly disposed between the outer wall of the water inlet body 10 and the inner wall of the outer sleeve pipe 30, and define the axial range of the water flow channel 40.

    [0022] In the embodiment, the water inlet body 10 is axially limited and sleeve coupled into the outer sleeve pipe 30, wherein the outer sleeve pipe 30 and the water outlet pipe 20 are integrally formed, or the outer sleeve pipe 30 and the water outlet pipe 20 are separately formed and then fixedly connected to each other by way of clamping, bonding, welding, or the like. Specifically, in the embodiment, the outer sleeve pipe 30 and the water outlet pipe 20 are integrally formed. The outer sleeve pipe 30 and the water outlet pipe 20 are detachable so as to facilitate the separate manufacture of the outer sleeve pipe 30 and the water outlet pipe 20, thereby simplifying the complexity of the single part, reducing the processing difficulty, and ensuring the processing quality thereof.

    [0023] In the embodiment, one end of the water inlet body 10 is provided with a limiting step 17 protruding outwards with the other end an outer thread 18. When the water inlet body 10 is sleeve coupled into the outer sleeve pipe 30, the limiting step 17 is axially limited and engaged with the end of the outer sleeve pipe 30, and the outer thread 18 of the other end of the water inlet body 10 passes through the outer sleeve pipe 30 and is in threaded engagement with a connecting nut having an outer diameter larger than that of the outer sleeve pipe 30. The connecting nut 100 is locked against the end of the outer sleeve pipe 30, such that the water inlet body 10 is axially limited in the outer sleeve pipe 30. Also, limit ribs are correspondingly disposed on the outer wall of the water inlet body 10 and the inner wall of the outer sleeve pipe 30, such that the water inlet body 10 is circumferentially limited in the outer sleeve pipe 30, thereby, the water inlet body 10 is limited and fixed in the outer sleeve pipe 30. A locking nut 110 is also included, which is in threaded engagement with a water inlet joint connected to one end of the outer thread 18 of the water inlet body 10 for locking the assembled water inlet body 10, the water outlet pipe 20, and the outer sleeve pipe 30 to the water tank body 1.

    [0024] In the embodiment, a water stop assembly capable of opening or closing the water inlet channel 11 is also included. The water stop assembly includes a float bowl 80 that can move up and down along with the water level of the water tank, and the float bowl 80 is movably disposed in a small water tank 70 relatively fixed to the water outlet pipe 20. The water inlet body 10 is provided with a back-pressure chamber 15 and a pressure relief opening 16 in communication with the back-pressure chamber 15. The float bowl 80 is, through a threaded rod 50, linked and engaged with a lifting rod 60 movably arranged on the water inlet body 10 and capable of opening and closing the pressure relief opening 16. A threaded sleeve 51 sleeve coupled and engaged with the threaded rod 50 is also included in the embodiment. The threaded sleeve 51 is sleeve coupled outside the threaded rod 50 and rotates synchronously with the threaded rod 50 in the circumferential direction, and movable relative to each other in the axial direction. The small water tank 70 is engaged with the thread 22 on the outer side wall of the water outlet pipe 20 by the threaded sleeve 51 for height adjustment. Specifically, a longitudinally disposed thread 22 is disposed on the water outlet pipe 20 at a position corresponding to the threaded sleeve 51, and the threaded sleeve 51 moves up and down by engaging with the thread 22 to drive the small water tank 70 to move up and down to realize the adjustment of the water level, of which the specific structure belongs to the prior art and no more details will be made here.

    [0025] In the embodiment, the outer sleeve pipe 30 and the water inlet body 10 are each provided with a relief hole, and the threaded rod 50 of the water stop assembly passes through the relief holes and is engaged and connected with the lifting rod 60 of the water stop assembly above the outer sleeve pipe 30 and the water inlet body 10. Specifically, a first relief hole 32 is disposed at one end of the outer sleeve pipe 30, and a second relief hole 13 is disposed at the corresponding position of the water inlet body 10, and the threaded rod passes through the first relief hole 32 and the second relief hole 13 respectively and is engaged and connected with the lifting rod 60.

    [0026] In the embodiment, an air inlet hole 31 in communication with the water flow channel 40 is disposed at the top of the outer sleeve pipe 30, and an anti-siphon pad 91 capable of opening or closing the air inlet hole 31 is also included. Specifically, an anti-siphon seat 90 is movably disposed in the water inlet body 10, and the anti-siphon pad 91 is fixed on the anti-siphon seat 90. When water flows into the side water inlet valve, the water pressure pushes the anti-siphon seat 90 such that the anti-siphon pad 91 closes the air inlet hole 31, thereby preventing the water flow from escaping from the air inlet hole 31. When a negative pressure occurs in the water inlet channel 11, the anti-siphon seat 90 falls under its own gravity to drive the anti-siphon pad 91 to open the air inlet hole 31, such that the outside air can enter the water inlet channel 11 to break the negative pressure and prevent the occurrence of the siphon backflow phenomenon.

    [0027] With the above structure, the structure and appearance of the product are greatly adjusted compared with the existing side water inlet valve, and the appearance of the product is more beautiful, novel and holistic; moreover, some parts of the water inlet body of the existing side water inlet valve may be omitted by the use of the outer sleeve pipe, such that the product is simple in structure and good in assembly manufacturability, thereby achieving the effect of reducing the cost.

    [0028] According to another aspect of the application, a flush toilet is also provided in the embodiment, wherein the flush toilet includes a water tank and the above-described water inlet valve, wherein the water inlet valve is installed in the water tank for replenishing the water tank.
