[0002] Closestools are sanitary appliances with which modern people have to be in contact everyday, and the sanitary requirement for the closestools is also higher and higher along with the improvement of the living quality of people. At the beginning, a closestool has the effects of defecating and flushing only, namely water in a water tank directly flushes an excretion inlet of an excretion pipeline directly passing through a water outlet of a closestool base, but the inner wall of the closestool base cannot be automatically cleaned. More or less excreta may adhere to the inner wall of the closestool base during defecation, and thus the excreta has to be manually cleaned.

[0003] For this problem, those skilled in the art have invented a closestool (as shown in FIG. 5), with an effect of automatically cleaning the inner wall of the closestool base, of which the patent number is 200320100838.5, a water draining passage is formed in the upper edge of the inner wall of the closestool base, and water enters into the water draining passage from the water tank and then flows out from a washing water outlet hole, so that the effect of automatically cleaning the inner wall of the closestool base is realized. However, in a long-term use condition, water stains are easily generated on the lower edge of the washing water outlet hole, and the water stains are difficult to be cleaned; when no water exists, dirt is easily hidden in the water draining passage, for example, insects such as cockroaches and centipedes can climb in the water draining passage from the washing water outlet hole, which is frightening and insanitary. Moreover, the washing water outlet hole is usually hidden in the inner side of the water draining passage for aesthetics, so that the closestool is more difficult to be cleaned.

SUMMARY OF THE INVENTION

[0004] In order to solve the above technical problem, the present invention provides a closestool base which is convenient to clean, simple in structure, durable and low in manufacturing cost, and the inner wall of the closestool base can be automatically cleaned.

[0005] The closestool base comprises a water draining channel, a water flowing pipe, a water storage cavity and a water baffle plate, wherein the water draining channel is arranged in the upper part of the inner wall of the closestool base in an encircling way; a water inlet of the water flowing pipe is arranged in the back of the closestool base and is communicated with a water tank; a water outlet of the water flowing pipe faces to the inner wall of the closestool base; the water storage cavity is arranged between the water outlet of the water flowing pipe and the water inlet of the water flowing pipe, and the water draining capability of the water inlet is higher than that of the water outlet; the water baffle plate for covering the water outlet is arranged at the upper part of the closestool base, a gap is formed between the left end and the right end of the water baffle plate and the water draining channel, and a gap is formed between the lower end of the water baffle plate and the inner wall of the closestool base; two vertical ribs are arranged at the back of the water baffle plate, the vertical ribs face to the water outlet, and the water baffle plate, the vertical ribs and the water storage cavity are integrally formed in a firing way with the closestool base respectively.

[0006] The water outlet is semicircular, and the upper half thereof is in a semicircular hollow shape.

[0007] The water inlet is circular, and the diameter of the water outlet and the diameter of the water inlet are the same.

[0008] The lower edge of the water outlet is higher than the bottom wall of the water storage cavity.

[0009] The vertical ribs of the water baffle plate run through the upper end and the lower end of the whole water baffle plate, and divide the water baffle plate into three parts, namely a left area, a middle area and a right area.

[0010] Dents are formed in the lower parts of the left area and the right area of the water baffle plate. The lower ends of the two vertical ribs are connected with the inner wall of the closestool base. The lower edge of the water baffle plate is positioned below the lower edge of the water outlet. The diameters of the water inlet and the water outlet are 4-6 cm.

[0011] The vertical ribs are 0.3-0.8 cm in thickness, 1-2 cm in height and 5-8 cm in length.

DESCRIPTION OF EMBODIMENTS

[0015] A closestool base in the embodiment as shown in FIG. 1 comprises a water draining channel 1, a water flowing pipe 6, a water storage cavity 4 and a water baffle plate 5; the water draining channel 1 (FIG. 6) is arranged in the upper part of the inner wall 7 of the closestool base in an encircling way, and the two ends of the water draining channel 1 are connected with a water outlet 2; a water inlet 2 of the water flowing pipe 6 is arranged in the back of the closestool base and is communicated with a water tank; a water outlet 3 of the water flowing pipe 6 faces to the inner wall 7 of the closestool base; the water storage cavity 4 is arranged between the water outlet 3 of the water flowing pipe 6 and the water inlet 2 of the water flowing pipe 6, and the water draining capability of the water inlet 2 is higher than that of the water outlet 3; the water baffle plate 5 for covering the water outlet 3 is arranged at the upper part of the closestool base, a gap is formed between the left end and the right end of the water baffle plate 5 and the water draining channel 5, and a gap is formed between the lower end of the water baffle plate 5 and the inner wall 7 of the closestool base; two vertical ribs 51 running through the upper end and the lower end of the whole water baffle plate 5 are arranged at the back of the water baffle plate 5 as shown in FIG. 3, the water baffle plate 5 is divided into three parts, namely a left area A, a middle area B and a right area C, and the vertical ribs 51 face to the water outlet 3. The water baffle plate 5, the vertical ribs 51 and the water storage cavity 4 are integrally formed in a-firing way with the closestool base respectively.

[0016] During water flushing of the closestool base in the embodiment, as shown in FIG. 2 and FIG. 4, water in the water tank firstly enters into the water storage cavity 4 from the water inlet 2 of the water flowing pipe 6 and then flows out from the water outlet 3, and a water flow is divided into three water flows after encountering the two vertical ribs 51 of the water baffle plate 5; as shown by arrows in FIG. 4, the water flows divided to the left area A and the right area C of the water baffle plate 5 are guided into the water draining channel 1 for cleaning the inner wall 7 of the closestool base; as shown by arrows in FIG. 2, the water flow divided to the middle area B of the water baffle plate 5 directly flows into the inner wall 7 of the closestool base positioned below the water baffle plate and is used for flushing dirt. Therefore, the effect of automatically cleaning the inner wall of the closestool is realized, and the water draining passage inside the ring of the closestool base does not need to be set, so that the problem that accumulated dirt in the water draining passage is difficult to clean is avoided, and people do not worry about the cockroaches climbing in the closestool; a ceramic structure is integrally formed in the firing way, the closestool is simple to assemble and durable, and the vertical ribs not only realize the effect of water distribution and pressure reduction but also can strengthen the structural strength of the water baffle plate.

[0017] Preferably, the water outlet 3 is semicircular, the upper half thereof is in a semicircular hollow shape, and the lower edge of the water outlet 3 is higher than the bottom wall of the water storage cavity 4; the water inlet 2 is circular, and the diameter of the water outlet 3 and the diameter of the water inlet 2 are the same. The semicircular structure is simple and easily formed in the firing way; the diameter of the water inlet 2 is the same as that of the water outlet 3 while the water outlet 3 is semicircular, the water draining capability of the water inlet 2 is twice of that of the water outlet 3, thus firstly, most of the water entering into the water flowing pipe 6 is temporarily stored in the water storage cavity 4 and then gradually flows out from the water outlet 3, so that the speed of the water flow is reduced and a better water distribution effect is realized; moreover, a portion of water is stored in the water storage cavity 4 all the time, and thus some insect pests such as cockroaches and centipedes cannot be hidden in the water inlet 3.

[0018] Preferably, dents 52 are formed in the lower parts of the left area A and the right area C of the water baffle plate 5. The dents 52 can adjust the moving direction of the water flow to form a small eddy, so that the water flow moves towards the direction of the water draining channel 1.

[0019] Preferably, the lower ends of the two vertical ribs 51 are connected with the inner wall 7 of the closestool base. On one hand, the effect of water distribution is further realized, and on the other hand, the structural strength of the water baffle plate 5 can also be further strengthened.

[0020] Preferably, the lower edge of the water baffle plate 5 is positioned below the lower edge of the water outlet 3. Such arrangement can enable the water flow to be sufficiently blocked by the water baffle plate 5, and thus the water flow can enter into the interior of the closestool base after being distributed by the water baffle plate 5.

[0021] Preferably, the diameters of the water inlet 2 and the water outlet 3 are 4-6 cm, and the vertical ribs 51 are 0.3-0.8 cm in thickness, 1-2 cm in height and 5-8 cm in length. The size is appropriate, 4-6 liters of water is consumed for flushing every time and is just the water volume for completing once flushing, so that the use of flushing water is effectively saved; a portion of water passes through the inner wall 7 and then flows into a discharge pipeline during flushing and dirt discharging, and the water flow enters the inlet of the discharge pipeline in all directions, so that the capacity of flushing and dirt discharging is greatly strengthened. Experiments show that the flushing work can be completed by needing only 2.7 liters of water during urine flushing and the flushing work can be competed by needing only 4.5 liters of water during defecate flushing, so that the using amount of the flushing water is greatly reduced.

[0022] The closestool base has the beneficial effects as follows. Firstly, an open water draining channel 1 is adopted for taking the place of a closed water draining passage, so that the purposes of automatically cleaning the inner wall 7 of the closestool base is realized, and the problems that dirt is hidden in the water flowing passage and the water flowing passage is inconvenient to clean are solved; secondly, the water baffle plate 5, the vertical ribs 51 and the closestool base are integrally formed in the firing way, and the structure is durable and reliable; thirdly, the water baffle plate 5 is simple in structure and convenient to produce; fourthly, the water flowing pipe 6 is provided with the water storage cavity 4, and thus some insect pests such as cockroaches and centipedes cannot be hidden in the water inlet 2; fifthly, a portion of water passes through the inner wall 7 and then flows into the discharge pipeline during flushing and dirt discharging, and the water flow enters the inlet of the discharge pipeline in all directions, so that the capacity of flushing and dirt discharging is greatly strengthened, and thus the using amount of the flushing water is reduced, and the effect of flushing and dirt discharging can be realized by needing only 4.5/2.7 liters (defecate/urine)of water amount.

[0023] Finally, it should be noted that the above-mentioned embodiments are only used for illustrating the technical solution of the present invention but not restricting the scope of protection of the present invention; although the present invention is described in detail by reference to preferable embodiments, those skilled in the art should understand that the technical solution of the present invention can be amended or equally substituted without departing from the spirit and scope of the technical solution of the present invention.
