Description

Technical Field

[0001] The present application is applied to the technical field of smart bathrooms, and in particular to a water tank and a smart toilet. Background Art

[0002] Some smart toilets on the market now have a water tank built into the toilet body. The built-in water tank stores tap water in it. When the user needs to flush or use the user cleaning function on the smart toilet, the water in the water tank will be used. In order to meet the requirements of preventing sewage backflow, an air isolation solution needs to be made in the built-in water tank.

[0003] However, the air isolation and anti-backflow technology currently on the market is basically guaranteed by a single air isolation valve, which only implements reverse blocking through structural sealing. When the seal fails, it cannot completely guarantee air isolation and prevent sewage from backflowing into the user's home water supply. Or in the case of a single overflow water tank solution, after the water level switch fails, the water in the water tank flows into the ceramic pit through the overflow channel. However, when the ceramic pit is blocked, the dirty sewage in the pit will also enter the water tank through the overflow channel. When the overflow water volume is large enough, sewage will enter the water inlet of the water tank and return to the household tap water, polluting the user's tap water. Utility Model Content

[0004] The present application provides a water tank to solve the problem in the prior art that dry water can enter into the household tap water through a water inlet pipe.

[0022] See also Figure 1 , Figure 1 This application provides water tank explosion Figure 1 A schematic structural diagram of an embodiment.

[0023] The present application provides a water tank. Figure 1 As shown, the water tank of this embodiment includes a shell 10, a first overflow port 30, a second overflow port 40 and a first overflow channel 301. The shell 10 is formed with a first accommodating space 501, and a water inlet 20 is provided at the upper end of the shell 10. The water inlet 20 can be connected to a tap water pipe, connected to domestic tap water, so as to input tap water into the first accommodating space 501 of the shell 10. The side wall of the shell 10 is provided with a first overflow port 30 and a second overflow port 40, one end of the first overflow channel 301 is connected to the side wall of the shell 10, and extends in a direction away from the shell 10, and the first overflow port 30 is located above the connection position of the shell 10 with the first overflow channel 301. The first overflow port 30 and the second overflow port 40 can be arranged on the side wall of the shell 10 relative to each other, for example, the first overflow port 30 and the second overflow port 40 are respectively provided on the front and rear sides of the shell 10, and the present application does not make specific limitations here.

[0024] In an optional embodiment, if Figure 1As shown, a first accommodating space 501 is formed in the shell 10, and a water inlet 20 is arranged at the upper end of the shell 10, so that water can be transported to the first accommodating space 501. By arranging a first overflow port 30 on the side wall of the shell 10, after the water level in the first accommodating space 501 rises, when the water level rises to the overflow height of the first overflow port 30, the sewage in the first accommodating space 501 can flow out through the first overflow port 30, and after the sewage flows out through the first overflow port 30, the sewage flows out through the first overflow channel 301 extending away from the shell 10 through the connecting box on the side wall of the shell 10, and the first overflow port 30 is located above the connection position between the shell 10 and the first overflow channel 301, wherein the first overflow channel 301 can be a water pipe, or other structures capable of discharging sewage, such as: a sink, which is not specifically limited in this application. That is, there is a certain height difference between the first overflow port 30 and the first overflow channel 301. After the sewage water level reaches the first overflow port 30, the sewage flows out through the first overflow port 30. Due to the existence of the height difference, the sewage can be quickly discharged through the first overflow channel 301, and the overflow height of the first overflow port 30 will not be flush with the first overflow channel 301, resulting in a slow drainage speed. Since there is a height difference between the first overflow port 30 and the water inlet 20, the sewage water level is effectively prevented from rising and entering the water inlet 20 above the shell 10.

[0025] Furthermore, the first overflow port 30 can only handle some overflow water volume that is small, that is, the water level rises slowly. For example, the water inlet 20 continuously delivers tap water into the first accommodating space 501. At this time, the first overflow port 30 can fully meet the effect of sewage discharge. However, when the overflow water volume is large enough, that is, the water level rises quickly, the drainage efficiency of the first overflow channel 301 is low. Therefore, a second overflow channel is opened on the side wall of the shell 10. The overflow height of the second overflow channel is higher than the height of the first overflow channel 301. After the sewage water level rises to the overflow height of the second overflow port 40, the sewage is discharged through the second overflow port 40. Among them, a second overflow channel can also be provided below the second overflow port 40, so as to facilitate the rapid discharge of sewage, thereby preventing the sewage from entering the domestic tap water through the water inlet 20 when the sewage overflow water volume is large.

[0026] In the above embodiment, by setting the first overflow port 30 on the side wall of the shell 10, and connecting the first overflow channel 301 on the side wall of the shell 10, the first overflow port 30 is located above the connection position of the shell 10 with the first overflow channel 301. After the sewage water level reaches the overflow height of the first overflow port 30, the sewage can be quickly discharged through the first overflow channel 301. By opening the second overflow port 40 on the side wall of the shell 10, when the overflow water volume of the sewage is large, the sewage can be further quickly discharged, that is, the first overflow channel 301 and the second overflow channel can effectively prevent the sewage from entering the domestic tap water through the water inlet 20.

[0027] In an optional embodiment, if Figure 2 As shown, the housing 10 includes a first housing 101 and a second housing 102, and the first housing 101 and the second housing 102 are detachably connected to form a second accommodating space 502. The first accommodating space 501 is formed in the first housing 101, and the first accommodating space 501 is located above the second accommodating space 502. That is, through the detachable connection between the first housing 101 and the second housing 102, the housing 10 can be disassembled to repair the water tank when a device inside the water tank fails, and the water tank installation is convenient. By forming the first accommodating space 501 in the first housing 101, and forming the second accommodating space 502 by connecting the first housing 101 and the second housing 102, tap water enters the first accommodating space 501 through the water inlet 20, and the first accommodating space 501 is located above the second accommodating space 502, and tap water enters the second accommodating space 502 through the first accommodating space 501 for storage. That is, tap water is stored in the second accommodating space 502, which can isolate the air and effectively prevent the air in the sewage from entering the domestic tap water through the drain pipe 90. Furthermore, a drain pipe 90 connected to the external components is provided at the bottom of the second housing 102, that is, the tap water in the second accommodating space 502 is discharged through the drain pipe 90.

[0028] In an optional embodiment, the first overflow port 30 and the second overflow port 40 are both located on the side wall of the first shell 101, and the overflow height of the second overflow port 40 is higher than the height of the first overflow port 30. That is, the first overflow port 30 and the second overflow port 40 are opened on the side wall of the first shell 101, and after the sewage enters the first accommodating space 501 through the second accommodating space 502, the sewage can be discharged through the first overflow port 30 and the second overflow port 40. Since the height of the second overflow port 40 is higher than the height of the first overflow port 30, when the sewage overflow flow is small, the sewage can be discharged through the first overflow port 30. When the sewage overflow flow is large, the drainage efficiency of the first overflow port 30 is low. Therefore, the sewage can be discharged through the second overflow port 40 higher than the first overflow port 30. Further, the first overflow port 30 and the second overflow port 40 can be provided on the first shell 101 in plurality, for example, three, four, etc. That is, by opening a plurality of first overflow channels 301 and second overflow channels on the first shell 101, sewage can be discharged in more extreme cases, thereby effectively preventing sewage backflow. For example, only the first overflow channel 301 and the second overflow channel are opened on the first shell 101, and sewage still cannot be discharged quickly.

[0029] In an alternative embodiment, if Figure 2As shown, a sensor 60 is provided on the second housing 102, and the sensor 60 is located in the second accommodation space 502 to detect the water level in the second accommodation space 502, wherein the sensor 60 can detect whether the second accommodation space 502 is lacking water or full of water. When lacking water, the water inlet 20 is opened to start conveying tap water into the second accommodation space 502, and when the water level in the second accommodation space 502 reaches the detection position of the sensor 60, the water inlet 20 is closed and the tap water is no longer conveyed to the second accommodation space 502. The height of the sensor 60 can be adjusted to control the water level in the second accommodation space 502 according to actual needs, and can also be fixedly set in the second accommodation space 502, which is not specifically limited in this application. Therefore, by setting the sensor 60 on the second housing 102, and the sensor 60 is located in the second accommodation space 502, the water level in the second accommodation space 502 can be monitored, so as to determine whether the second accommodation space 502 is lacking water or full of water.

[0030] Specifically, a shell cover 70 is buckled on the second shell 102, the first shell 101 is arranged at the edge of the shell cover 70, the first shell 101 is connected to the second shell 102 through the shell cover 70, and the sensor 60 is arranged on the shell cover 70. Among them, a through hole (not shown) penetrating the shell cover 70 is opened on the shell cover 70, one end of the sensor 60 can be fixedly connected to the through hole by bolts, and the other end of the sensor 60 is inserted into the second accommodating space 502 through the through hole. The sensor 60 can also be bonded to the shell cover 70 by glue or the like, and the present application does not make specific limitations here. Therefore, the shell cover 70 is buckled on the second shell 102, and the sensor 60 is installed on the shell cover 70. When the sensor 60 fails, the sensor 60 can be directly removed. Figure 3 As shown, the first shell 101 is connected to the second shell 102 through the shell cover 70, that is, the cover is provided with a channel 701 connecting the first accommodating space 501 and the second accommodating space 502. After the water inlet 20 delivers tap water to the first accommodating space 501, the tap water in the first accommodating space 501 enters the second accommodating space 502 through the channel 701. The first shell 101 is arranged at the edge of the shell cover 70, that is, when the sewage enters the first accommodating space 501 through the second accommodating space 502, the impact force of the sewage can be reduced, thereby effectively preventing the sewage from directly entering the water inlet 20 when it impacts quickly, and then entering the domestic tap water to pollute the tap water.

[0031] In an optional embodiment, a cover plate 80 is provided at the upper end of the first shell 101, a water inlet 20 is provided on the cover plate 80, and a water inlet pipe is connected to the water inlet 20. Therefore, by providing the cover plate 80 at the upper end of the first shell 101, the cover plate 80 and the first shell 101 form a first accommodating space 501 for transmitting tap water, the water inlet 20 is provided on the cover plate 80, the water inlet pipe is connected to the water inlet 20, and the tap water in the water inlet pipe is transported through the water inlet 20. In this embodiment, a buckle 801 is provided on the cover plate 80, and a clamping member 802 adapted to the buckle 801 is provided on the side wall of the first shell 101, so that the cover plate 80 can be detachably connected to the first shell 101. Therefore, the buckle 801 on the shell cover 70 can be snapped onto the snap-on piece 802 on the side wall of the first shell 101, that is, the shell cover 70 and the first shell 101 are detachably connected, and when installing the water inlet pipe, the water inlet pipe can be first installed on the water inlet 20 of the cover plate 80, and then the cover plate 80 can be installed on the first shell 101. And when a fault occurs in the first accommodating space 501, the cover plate 80 can be removed to repair the components inside the first accommodating space 501.

[0032] In a specific application scenario, a water tank is set inside a smart toilet, and the drain pipe 90 at the bottom of the second housing 102 is connected to the ceramic pit. After the installation is completed, the tap water in the water inlet pipe enters the first accommodation space 501 of the first housing 101 through the water inlet 20, and the tap water in the first accommodation space 501 enters the accommodation space of the second housing 102 through the channel 701 of the shell cover 70. After the water level in the second accommodation space 502 reaches the height of the sensor 60, the sensor 60 controls the water inlet 20 to stop the water intake. After the water in the second accommodation space 502 is discharged through the drain, the sensor 60 detects that the second accommodation space 502 is short of water, and the water inlet 20 starts to take in water so that the second accommodation space 502 is full of water.

[0033] In the present embodiment, when the sensor 60 fails, the water inlet 20 will always be in a water inlet state. At this time, the water level inside the second shell 102 will continue to rise, and the sewage inside the second shell 102 will enter the first accommodating space 501 of the first shell 101 through the channel 701. The sewage in the first accommodating space 501 rises to the overflow height of the first overflow port 30, and the sewage in the first accommodating space 501 can flow out through the first overflow port 30. After the sewage flows out through the first overflow port 30, it passes through the first overflow channel 301 arranged below the first shell 101. Since there is a height difference between the first overflow channel 301 and the first overflow, the sewage is quickly discharged from the first overflow port 30. There is a height difference between the first overflow port 30 and the water inlet 20, which effectively prevents the water level of the sewage from rising to the water inlet 20 and entering into the domestic tap water.

[0034] Furthermore, when the ceramic pit is blocked, the sewage in the second accommodating space 502 in the second shell 102 will rise rapidly, and the sewage will quickly impact into the first accommodating space 501. Since the first shell 101 is arranged at the edge of the cover plate 80, the impact force of the sewage is effectively prevented from being reduced, thereby directly impacting into the water inlet 20. After the sewage water level rises to the first accommodating space 501 of the first shell 101, due to the fast rising speed of the sewage, after the sewage reaches the overflow water level of the first overflow port 30, the sewage is discharged through the first overflow port 30 and the first overflow channel 301. However, at this time, due to the limited drainage efficiency of the first overflow port 30, it is insufficient to completely discharge the sewage. After the sewage water level continues to rise to the overflow height of the second overflow port 40, the sewage will be directly discharged through the second overflow port 40. Moreover, due to the height difference between the second overflow port 40 and the water inlet 20, the sewage is effectively prevented from entering the domestic tap water through the water inlet 20, thereby polluting the domestic tap water.

[0035] In the above manner, the present application sets a first overflow port 30 on the side wall of the housing 10, connects a first overflow channel 301 on the side wall of the housing 10, and the first overflow port 30 is located above the connection position of the housing 10 with the first overflow channel 301, and opens a second overflow port 40 on the side wall of the housing 10. When the amount of sewage overflow is large, the sewage can be further discharged quickly, that is, the first overflow channel 301 and the second overflow channel can effectively prevent the sewage from entering the domestic tap water through the water inlet 20. By setting the first housing 101 and the second housing 102 to be detachable and forming a second accommodating space 502, the housing 10 can be disassembled to repair the water tank when a device inside the water tank fails, and the water tank installation is convenient. By setting a second overflow port 40 higher than the first overflow port 30 on the first housing 101, when the sewage overflow flow is large, the drainage efficiency of the first overflow port 30 is low, and the sewage can be discharged through the second overflow port 40 higher than the first overflow port 30. By setting a sensor 60 located inside the second accommodating space 502 on the second shell 102, the sensor 60 can detect whether the second accommodating space 502 is short of water or full of water. By setting a shell cover 70 on the second shell 102 and setting the first shell 101 at the edge of the shell cover 70, when sewage enters the first accommodating space 501 through the second accommodating space 502, the impact force of the sewage can be reduced, thereby effectively preventing the sewage from directly entering the water inlet 20 during rapid impact, thereby entering the domestic tap water and contaminating the tap water. A detachable cover plate 80 is set on the first shell 101, which can facilitate the installation of the water inlet pipe at the water inlet 20, and when a fault occurs inside the first accommodating space 501, the detachable cover plate 80 can be used to repair the components inside the first accommodating space 501.

[0036] The present application also provides a smart toilet, which includes: a water tank, which is arranged inside the smart toilet, and the water tank is the water tank of any of the above-mentioned embodiments.
