    Description

    FIELD



    [0001] The present disclosure relates to an atomizer and an electronic cigarette with same, and more particularly, to an atomizer with side liquid injection and an electronic cigarette with same.

    BACKGROUND



    [0002] The electronic cigarette, also known as virtual cigarette, electronic atomizer, and electronic cigar, has similar taste as that of an ordinary cigarette.

    [0003] An atomizer is a part of the electronic cigarette. There are mainly two ways of liquid injection for the atomizer currently on the market: top liquid injection and basal liquid injection. Wherein, by the top liquid injection, it is usually required to open the top cover of the atomizer or remove the atomizer from the electronic cigarette so as to expose the injection port for injecting liquid. Due to the communication between the liquid storage chamber and the atomizing chamber and the specified hydraulic pressure difference therebetween, the pressure generated during the top liquid injection tends to cause the cigarette liquid pass through the cigarette liquid chamber and the liquid inlet and flow into the atomizing chamber, resulting in the atomizer leakage. Additionally, the operation of the basal liquid injection is troublesome, which requires to invert the electronic cigarette and open the base for liquid injection. Since the base is connected to the atomizer by screw thread, cigarette liquid are likely to spill from the thread connection part. Both the two ways may lead to complicated operation of the liquid injection of the atomizer, and the difficulty to clean the atomizer and/or the electronic cigarette

    [0004] Documents EP 2 823 720, CN 104 082 863 and WO 2014/195859 also disclose electronic cigarettes with injection ports.

The terms in the specification of the present disclosure are only for describing the specific embodiments, are not intended to limit the present disclosure. The use of the term "and/or" in the description includes one or more related affairs purpose by any and all combinations.

    [0024] Please refer to FIGS. 1-2. A preferred embodiment of the present disclosure provides an atomizer 100. The atomizer 100 includes a top cover 120, a liquid retainer 130, a liquid storage chamber 160, an atomizing pipe 170, an atomizing assembly 180 and a base 190. The opposite ends of the atomizing pipe 170 are coupled to the top cover 120 and the base 190 respectively. The liquid storage chamber 160 and the atomizing assembly 180 are positioned within the atomizing pipe 170. The liquid retainer 130 is movably arranged on the atomizing pipe 170. The atomizing assembly 180 is fixed on one end of the base 190. In the embodiment, the top cover 120 or the base 190 may limit the liquid retainer 130 to move along an axial direction of the atomizing pipe 170. In other embodiments, the movements of the liquid retainer 130 can be limited by other ways, as long as it is convenient for injection and avoiding liquid leakage.

    [0025] The atomizing pipe 170 is provided with an injection port 171 configured to make the inside of the atomizing pipe 170 in communication with the external environment, that is, the user may use the injection port 171 to move liquid into the liquid storage chamber 160.

    [0026] The liquid retainer 130 is provided with an injection window 131 capable of being in communication with the injection port 171. The size of the injection port 171 may be larger, smaller or equal to the size of the injection window 131. In the embodiment, the liquid retainer 130 may be a liquid retaining ring rotatably arranged on the atomizing pipe 170. The injection port 171 and the injection window 131 may be superposed, and the injection port 171 may be in communication with the external environment, by turning the liquid retainer 130 (which may drive the injection window 131 provided thereon to rotate), to achieve the side injection of the atomizing pipe 170. Specifically, when turning the liquid retainer 130, if the injection port 171 is covered by the liquid retainer 130, the atomizer 100 is in a closed state, and if the injection window 131 and the injection port 171 are superposed, the atomizer 100 is in a state to be injected and is injectable.

    [0027] Also see FIG. 3, further, a sealing groove 172 configured to mount a sealing element 150 is arranged on an outer diameter surface of the atomizing pipe 170 and around the injection port 171. The sealing element 150 is arranged between the atomizing pipe 170 and the liquid retainer 130. The sealing element 150 is configured to seal the cigarette liquid to prevent the cigarette liquid from spilling from the liquid storage chamber 160 when the atomizer 100 is in a closed state. The sealing element 150 may be made of silicone, rubber or others. In the embodiment, there are two sealing grooves 172, and each sealing groove 172 is mounted with a sealing element 150.

    [0028] Further, the atomizer 100 includes a stopper 132 configured to removably hold the liquid retainer 130 on the atomizing pipe 170, to prevent the user from turning the liquid retainer 130 to a state to be injected which may cause the cigarette liquid in the liquid storage chamber 160 spill out. In the embodiment, the stopper 132 is arranged on the inner wall of the liquid retainer 130. The outer wall of the atomizing pipe 170 is provided with a limiting groove 177 that matches the stopper 132. The stopper 132 may be an elastic element. When the user turn the liquid retainer 130 to drive the stopper 132 to slide into the limiting groove 177, the liquid retainer 130 may be clamped to prevent the user from turning the liquid retainer 130 to a state to be injected. It should be understood that, in other embodiments, when the stopper 132 is held in the limiting groove 177, the atomizer 100 is in a state to be injected, and when the stopper 132 is removed from the limiting groove 177, the atomizer 100 is in a closed state.

    [0029] It should be understood that, the stopper 132 may be arranged on the atomizer 100, and the limiting groove 177 may be arranged on the liquid retainer 130. However, the implementation is not limited to the embodiment.

    [0030] Further, the atomizing pipe 170 includes a first pipe 173 and a second pipe 175 which matches the first pipe 173. The injection port 171 and the limiting groove 177 are arranged on the first pipe 173 respectively. The first pipe 173 may be made of metal material, and the second pipe 175 may be made of translucent material, such as plastics or glass.

    [0031] It should be understood that the first pipe 173 and the second pipe 175 may be made of the same material, and may be also made of different materials and not limited to the embodiment.

    [0032] It should be understood that the atomizing pipe 170 is integrally molded, or formed of two components removably or non-removably connected.

    [0033] Further, the atomizer 100 includes a gas outlet pipe 200. One end of the gas outlet pipe 200 is fixed on the top cover 120, and the other end of the gas outlet pipe 200 is fixed on the base 190. An atomizing chamber 210 is arranged within the gas outlet pipe 200. The atomizing assembly 180 is mounted within the atomizing chamber 210. When the cigarette liquid in the liquid storage chamber 160 flows into the atomizing chamber 210 through a liquid access port in the gas outlet pipe 200, the cigarette liquid may be absorbed by delivery cotton of the atomizing assembly 180, and be atomized by a heating element of the atomizing assembly 180.

    [0034] During the liquid injection of the atomizer 100 according to the present invention, none of the following operations are required: for example, opening the top cover 120, disassembling the atomizer 100 from the electronic cigarette, or opening the base 190. The liquid injection of the atomizer 100 according to the present disclosure is simple and convenient. Further, there is no pressure generated upon the cigarette liquid in the liquid storage chamber 160 to cause the cigarette liquid flow towards the atomizing chamber 210, and there is no cigarette liquid spilling from the injection port. Thus, the present disclosure has effectively solved the problems in the prior art: the top liquid injection may easily generate a pressure upon the cigarette liquid in the liquid storage chamber 160 by the cigarette liquid flow towards the atomizing chamber 210, which causes leakage of the atomizer 100, whilst the basal liquid injection is troublesome in operation, easy to cause cigarette liquid spilling out and hard to clean the remained cigarette liquid in the atomizer.

    [0035] In another embodiment, one end of the liquid retainer 130 is rotatably mounted on the atomizing pipe 170 by being fixed on a rotating shaft, and the other end of the liquid retainer 130 is releasable locked on the atomizing pipe 170. When the other end of the liquid retainer 130 is released from the atomizing pipe 170, the injection port 171 may be in communication with the external environment by rotating the liquid retainer 130, such that the liquid injection is possible.

    [0036] In another embodiment, the liquid retainer 130 may be a liquid retaining ring arranged on the atomizing pipe 170 and is vertically moveable. One end of the liquid retainer 130 is provided with an elastic element; when the liquid retainer 130 moves towards the end provided with the elastic element, the cigarette liquid is injectable once the injection port 171 of the atomizing pipe 170 and the injection window 131 on the liquid retainer 130 are superposed. At the end of the liquid injection, by a reverse operation, the liquid retainer 130 can return to its initial position, and the atomizer 100 is in closed state.

    [0037] In another embodiment, the top and bottom sides or the left and right sides of the injection port 171 of the atomizing pipe 170 are provided with guiding grooves. The liquid retainer 130 is movably fitted in the guiding groove to realize the vertical or lateral movements. If the user moves the liquid retainer 130 to communicate the atomizing pipe 170 with the external environment, the atomizer 100 is in a state to be injected; otherwise the atomizer 100 is in a closed state.

    [0038] It should be understood that, the liquid retainer 130 is not limited to a liquid retaining ring in other embodiments, and the liquid retainer 130 can be a liquid retaining block of other shapes, such as in a shape of half ring, strip or sector.

    [0039] Please refer to FIG. 4. The present disclosure also provides an electronic cigarette 300 including the above atomizer 100. The electronic cigarette 300 further includes a cigarette holder 310 inserted into the top cover 120, and a battery pack 320 electrically connected with the atomizer 100.

    [0040] The above are preferred embodiments of the disclosure described in detail, and should not be deemed as limitations to the scope of the present invention. It should be noted that variations and improvements will become apparent to those skilled in the art to which the present disclosure pertains without departing from its scope. Therefore, the scope of the present disclosure is defined by the appended claims.
