Description

Technical Field

[0001] The present application relates to the technical field of toilets, and in particular to a water supply device and a toilet with an overflow function. Background Art

[0002] With the rapid development of smart toilets, more and more smart toilets are equipped with cleaning water circuits, which include a water supply device and a spray gun. The water supply device is used to supply water to the spray gun, and the spray gun can be extended into the toilet bowl to spray the user, thereby improving the user experience. Among them, the water supply device usually includes a water storage container and a water pump. The water pump is used to extract the liquid in the water storage container to supply water to the spray gun. However, in traditional smart toilets, the liquid in the water storage container is difficult to empty. After the spraying operation, there is usually liquid in the water storage container, which is easy to breed bacteria. When the interval between the spraying operations is long, it is also easy to cause the liquid to deteriorate, thereby affecting the health of the user. Summary of the invention

[0034] Please refer to Figures 1 to 4. Figures 1 and 2 are schematic diagrams of the structures of some components of the toilet at different angles in some embodiments, Figure 3 is a schematic cross-sectional diagram of some components of the toilet in some embodiments, and Figure 4 is a partial enlarged schematic diagram of the circular frame area of ​​the toilet shown in Figure 3. The toilet provided in the present application includes a toilet seat (not shown in the figure), a mounting seat 10, and a water supply device 20. The mounting seat 10 is arranged on the toilet seat, and the water supply device 20 is arranged on the mounting seat 10. The toilet seat is also provided with a toilet bowl. The water supply device 20 can be used to supply water to the spray water circuit of the toilet. The toilet can also include a spray gun (not shown in the figure) arranged on the toilet seat. The water supply device 20 is used to supply water to the spray gun. The spray gun can extend into the toilet bowl and spray cleaning water to the user to spray the user. Of course, the water supply device 20 provided in the present application can also be used in any other applicable products or scenarios that require water supply, and can also be used in other scenarios in the toilet that require water supply, such as for supplying water to the flushing waterway and foam shield waterway of the toilet siphon. In the present application, the water supply device 20 is used to supply water to the spray waterway as an example.

[0035] In some embodiments, the water supply device 20 includes a water storage container 21, and the water storage container 21 is used to store water for spraying when the spray gun performs a spraying operation. The toilet also includes a water supply pipe 11, and the water supply pipe 11 is connected to an external water source, such as a public pipe network. When the water supply device 20 performs a water supply operation, the liquid of the external water source can flow into the water storage container 21 through the water supply pipe 11. In conjunction with FIG. 5, the water supply device 20 also includes a water pump 22 and a water outlet pipe (not shown in the figure). The water pump 22 provides a power source for the water supply operation of the water supply device 20. The water pump 22 has a water inlet 221 and a water outlet 222. The water inlet 221 is connected to the water storage container 21, and the water outlet 222 is connected to the water outlet pipe. When the water supply device 20 performs a water supply operation, the water pump 22 can pump out the liquid in the water storage container 21 through the water inlet 221, and the liquid flows out from the water outlet 222 through the water outlet pipe. The water outlet pipe can be connected to the spray gun to provide spray water for the spray gun.

[0036] Furthermore, in some embodiments, an overflow hole 211 is provided at the bottom of the water storage container 21, and the water supply device 20 further includes an overflow assembly 23 disposed in the water storage container 21, and the overflow assembly 23 includes a housing 231, a blocking structure 233 and an elastic element 234 disposed in the housing 231. The blocking structure 233 is slidably disposed in the housing 231, and the blocking structure 233 is opposite to the overflow hole 211. The blocking structure 233 can move relative to the housing 231 toward the overflow hole 211 until the overflow hole 211 is blocked. When the blocking structure 233 blocks the overflow hole 211, the liquid in the water storage container 21 will not flow out of the water storage container 21 from the overflow hole 211, and when the blocking structure 233 is separated from the overflow hole 211, the liquid in the water storage container 21 can be discharged from the water storage container 21 from the overflow hole 211. The elastic element 234 includes but is not limited to an element capable of elastic deformation, such as a spring or rubber. The elastic element 234 abuts against the side of the blocking structure 233 facing the overflow hole 211. When the blocking structure 233 moves relative to the shell 231 toward the overflow hole 211 until the overflow hole 211 is blocked, the blocking structure 233 squeezes the elastic element 234 to cause the elastic element 234 to undergo elastic deformation. The overflow assembly 23 is formed with a first space 235 located on the side of the blocking structure 233 facing away from the overflow hole 211. The first space 235 can be formed by the blocking structure 233 and some parts of the shell 231, wherein the first space 235, the water outlet 222 and the water outlet pipe are interconnected.

[0037] It is understandable that during the water supply operation, when the water pump 22 supplies water to the water outlet pipe through the water outlet 222, the water flow will squeeze the air in the first space 235 and the water outlet pipe, causing the air pressure in the first space 235 to rise. Since the first space 235 is located on the side of the sealing structure 233 facing away from the overflow hole 211, the increase in the air pressure in the first space 235 will push the sealing structure 233 to move toward the direction close to the overflow hole 211 until the sealing structure 233 seals the overflow hole 211.

[0038] When the water supply device 20 is performing a water supply operation, the water pump 22 draws liquid from the water storage container 21 through the water inlet 221 and discharges the liquid through the water outlet 222 and the water outlet pipe to supply water to components such as a spray gun. Since the first space 235 is connected to the water outlet 222 and the water outlet pipe, the pressure of the water discharged by the water pump 22 will cause the air pressure in the first space 235 to increase, thereby pushing the blocking structure 233 to move toward the overflow hole 211 until the overflow hole 211 is blocked, so as to prevent the liquid in the water storage container 21 from being discharged from the overflow hole 211 during the water supply operation. When the sealing structure 233 blocks the overflow hole 211, the sealing structure 233 compresses the elastic element 234. After the water supply operation is completed, the water pump 22 stops pumping water from the water storage container 21. The air pressure in the first space 235 decreases, and the sealing structure 233 can be separated from the overflow hole 211 under the driving force of the elastic restoring force of the elastic element 234. The liquid in the water storage container 21 can be discharged from the overflow hole 211.

[0039] Therefore, the above-mentioned water supply device 20, the overflow component 23 and the water pump 22 are matched, and the pressure formed by the water pump 22 is used as the power of the sealing structure 233. During the water supply operation, the overflow hole 211 can be blocked to prevent the spray water from flowing out of the overflow hole 211 and affecting the water supply operation. After the water supply operation is completed, the overflow hole 211 can be opened and maintained in the open state, which is conducive to emptying the liquid in the water storage container 21 and will not affect the normal operation of the water supply operation.

[0040] In some embodiments, the toilet further comprises a water tank 12, which is provided with a water storage chamber 121. The water storage chamber 121 of the water tank 12 is used to store flushing water for flushing the siphon of the toilet. The water tank 12 is connected to the mounting seat 10, and the water storage container 21 is provided on the mounting seat 10 and located on the water tank 12, and the overflow hole 211 is opposite to the water storage chamber 121. Thus, when the water supply device 20 finishes the water supply operation and the overflow hole 211 is opened, the liquid in the water storage container 21 can flow from the overflow hole 211 into the water tank 12 and be stored in the water tank 12 as flushing water, which can avoid liquid leakage and reduce the waste of water resources.

[0041] As shown in combination with FIG. 4 and FIG. 5 , in some embodiments, the water supply device 20 further includes a tee 24, the tee 24 having a first interface 241, a second interface 242 and a third interface 243 that are interconnected, the first interface 241 can be connected to the water outlet 222 through a pipeline, the second interface 242 can be connected to the first space 235 through a pipeline, and the third interface 243 is connected to the water outlet pipeline. The tee 24 is provided to achieve the connection between the first space 235, the water outlet pipeline and the water outlet 222, which can simplify the arrangement of the water channel components and reduce the occupied space of the water supply device 20. In some embodiments, the water inlet 221 is connected to the water storage container 21 through a pipeline.

[0042] As shown in combination with FIG. 4 , FIG. 6 and FIG. 7 , in some embodiments, the housing 231 includes a first shell 2311 and a second shell 2316. The second shell 2316 is disposed in the first shell 2311. The second shell 2316 is a hollow structure with openings at both ends. The blocking structure 233 is slidably disposed in the second shell 2316. One end opening of the second shell 2316 is opposite to the overflow hole 211, so that the blocking structure 233 can slide along the second shell 2316 until the overflow hole 211 is blocked. The other end opening of the second shell 2316 is sealed and connected to the first shell 2311.

[0043] Further, in some embodiments, the first shell 2311 includes a cover 2312 and an outer shell 2313, the outer shell 2313 is arranged around the second shell 2316, the outer shell 2313 and the second shell 2316 are spaced apart, a channel 236 is formed between the outer shell 2313 and the second shell 2316, and the outer shell 2313 is provided with a first through hole 2314 connecting the channel 236 and the water outlet 222. The cover 2312 is connected to the outer shell 2313 and covers the second shell 2316, and the cover 2312 seals the opening of the second shell 2316. The cover 2312, the second shell 2316 and the blocking structure 233 are jointly enclosed to form a first space 235, and the second shell 2316 is further provided with a second through hole 2321 connecting the channel 236 and the first space 235. It is understandable that when the water outlet 222 of the water pump 22 is draining, the liquid flowing from the water outlet 222 to the water outlet pipe through the tee 24 will squeeze the gas, and the increase in gas pressure caused by the liquid squeezing the gas will be transmitted to the first space 235 through the tee 24, the first through hole 2314, the channel 236 and the second through hole 2321, thereby acting on the blocking structure 233, pushing the blocking structure 233 to block the overflow hole 211. The cover 2312, the shell 2313 and the second shell 2316 are matched in the overflow assembly 23. When the cover 2312 is separated from the shell 2313, it is more convenient to install and maintain the second shell 2316, the blocking structure 233 and the elastic element 234 in the shell 2313. The cover 2312 and the shell 2313 can also provide effective limiting, supporting and protecting functions for each component in the shell 2313, thereby improving the structural reliability and performance stability of the overflow assembly 23.

[0044] In some embodiments, the housing 2313 and the water storage container 21 are an integrated structure, for example, the housing 2313 and the water storage container 21 are prepared by an integrated molding process, and the overflow hole 211 is located in the portion of the water storage container 21 corresponding to the housing 2313. Thus, the structural reliability of the overflow assembly 23 can be further improved, and the alignment of the second shell 2316 and the blocking structure 233 and other components relative to the overflow hole 211 can be achieved by the precision design of the housing 2313 relative to the overflow hole 211, which is conducive to improving the installation precision of the overflow assembly 23 in the water storage container 21. It can be understood that the outer shell 2313 can be regarded as sharing a side wall with the water storage container 21, and the outer shell 2313 and the water storage container 21 are jointly enclosed to form a space for accommodating the second shell 2316. The first through hole 2314 can be arranged on the side wall shared by the outer shell 2313 and the water storage container 21, so that the tee 24 can be connected to the first through hole 2314 through a pipe, which is beneficial to simplify the water channel design of the water supply device 20 and improve the sealing performance of the overflow assembly 23 and the water storage container 21 around the first through hole 2314.

[0045] In some embodiments, the second shell 2316 is provided with a plurality of second through holes 2321, which are provided on the side of the blocking structure 233 facing away from the overflow hole 211 and are all connected to the first space 235, and the plurality of second through holes 2321 are sequentially spaced along the circumference of the second shell 2316. The air pressure acts on the blocking structure 233 through the plurality of second through holes 2321, which can increase the force acting on the blocking structure 233, and is conducive to smoothly driving the blocking structure 233 to block the overflow hole 211. The number of the second through holes 2321 includes but is not limited to two, three or more, and two are taken as an example in the drawings of the present application.

[0046] In some embodiments, the outer shell 2313 is further provided with a third through hole 2315 at a position corresponding to the bottom of the water storage container 21, and the second shell 2316 is provided with a fourth through hole 2322 opposite to the third through hole 2315, and the fourth through hole 2322 communicates with the third through hole 2315 and the overflow hole 211. When the overflow hole 211 is opened, the liquid in the water storage container 21 can be discharged from the overflow hole 211 through the third through hole 2315 and the fourth through hole 2322. In some embodiments, the second shell 2316 includes a main body 2317 and a sealing structure 2318 provided on the outer side of the main body 2317, the sealing structure 2318 is sealed and connected to the outer shell 2313, the second through hole 2321 and the fourth through hole 2322 are respectively located on opposite sides of the sealing structure 2318, and a sealing ring can be provided on the sealing structure 2318 to improve the sealing performance of the sealing structure 2318 and the outer shell 2313. It can be understood that the side of the sealing structure 2318 facing away from the overflow hole 211 is surrounded by the second shell 2316 and the outer shell 2313 to form a channel 236. The sealing structure 2318 can separate the channel 236 from the third through hole 2315 and the fourth through hole 2322 to prevent the channel 236 from connecting to the outside of the overflow component 23 and causing the overflow component 23 to fail.

[0047] In some embodiments, the second shell 2316 further includes a matching structure 2319 disposed inside the main body 2317, and the blocking structure 233 is slidably matched with the inner circumference of the matching structure 2319 to provide a limit for the axial movement of the blocking structure 233 along the second shell 2316. The radial dimension of the end of the blocking structure 233 away from the overflow hole 211 is greater than the radial dimension of the remaining part, and the elastic element 234 is sleeved on the blocking structure 233 and located between the end of the blocking structure 233 and the matching structure 2319, and the two ends of the elastic element 234 are respectively abutted against the end of the blocking structure 233 and the matching structure 2319. When the sealing structure 233 slides toward the direction close to the overflow hole 211, the end of the sealing structure 233 and the matching structure 2319 jointly compress the elastic element 234. When the water pump 22 stops running, the elastic force of the elastic element 234 can drive the end of the sealing structure 233 to move in the direction away from the matching structure 2319, thereby making the sealing structure 233 detach from the overflow hole 211.

[0048] In some embodiments, the blocking structure 233 includes a main body 2331 and a blocking portion 2332 disposed at one end of the main body 2331 near the overflow hole 211. The blocking portion 2332 includes but is not limited to any suitable flexible material such as rubber, and the blocking portion 2332 is fixed to the end of the main body 2331 by sleeve setting, buckling, etc. When the blocking structure 233 is close to the overflow hole 211, the blocking portion 2332 can squeeze the bottom wall of the water storage container 21 and block the overflow hole 211. The provision of the flexible blocking portion 2332 can enhance the sealing effect of the blocking structure 233 when blocking the overflow hole 211, and effectively prevent the liquid from being discharged from the water storage container 21 through the overflow hole 211.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
