Technical Field
[0001] The utility model relates to the field of intelligent toilets, in particular to an upward flushing assembly applied to an intelligent toilet. Background Art
[0002] An intelligent toilet is an upgraded product of an ordinary toilet. It is a toilet controlled by a microcomputer, with all the functions of an ordinary toilet. At the same time, it combines functions such as automatic flushing, seat heating, hip washing, massage for defecation, and warm air drying, which are very comfortable and practical. By using advanced technology, it integrates a toilet, a feminine washer, and a dryer, enabling people to change the habit of wiping with toilet paper during toileting and replacing it with more environmentally friendly and comfortable water flow cleaning and warm air drying, achieving a state of convenience, enjoyment, and health care.
[0003] An intelligent toilet is generally equipped with a water tank for flushing. In the case of a water supply interruption or water pressure fluctuation, an instantaneous negative pressure may be generated in the water supply pipeline. This negative pressure will cause the water flow in the pipeline to flow to the place with lower pressure, and the water may flow back into the water supply pipeline. Currently, the solution is to install a check valve on the drain pipe. However, it is extremely inconvenient when the water blocking parts inside the check valve are damaged and need to be repaired or replaced. Summary of the Utility Model
[0004] In order to facilitate the replacement and repair of the water blocking parts, the present application provides an upward flushing assembly applied to an intelligent toilet.
[0005] The upward flushing assembly applied to an intelligent toilet provided by the present application adopts the following technical solutions:
[0006] An upward flushing assembly applied to an intelligent toilet includes a valve body, a cover body, and a plug. The top end of the valve body has a communication cavity, and the cover body is detachably connected to the top end of the valve body to cover the communication cavity;
[0007] The valve body has a first channel and a second channel arranged vertically. The top ends of the first channel and the second channel communicate with the communication cavity respectively, forming a first communication port and a second communication port. The valve body is also provided with a water inlet communicating with the first channel and a water outlet communicating with the second channel;
[0008] A through hole is penetrated through the cover body corresponding to the position of the first communication port. The plug is vertically slidably sleeved in the through hole, and the lower end of the plug has a sealing portion;
[0009] Wherein, when a negative pressure is formed in the first channel relative to the communication cavity, the plug slides downward and drives the sealing portion to block the first communication port; when there is an upward water flow in the first channel, the plug slides upward and drives the sealing portion to block the through hole.
[0010] By adopting the above technical solution, when flushing water, the water enters the first channel from the water inlet, and the water pressure will drive the plug to move upward. At this time, the plug moves away from the first communication port, and the water can enter the second channel from the communication cavity and then flow out from the water outlet to flush the intelligent toilet; when not flushing water, the plug blocks the first communication port under the action of gravity, and the water in the second channel cannot flow back to the first channel. At the same time, in the case of water cut-off or water pressure fluctuation, a negative pressure is generated in the first channel, which will act on the plug to adsorb it, and the plug can closely adhere to the bottom wall of the communication cavity, playing a better blocking role; when the plug is damaged, only the cover needs to be disassembled and the plug needs to be replaced. There are no complex parts and structures, and the replacement is simple.
[0011] Preferably, the plug is provided with a hollow structure, and air vents are provided on the side and top surfaces.
[0012] By adopting the above technical solution, since there is usually an overflow port inside the toilet, the position of the water outlet is lower than that of the overflow port, so even if there is backflow, it will not flow back into the second channel. However, the backflow will cause a change in the air pressure in the second channel, so the setting of the air vents can balance the air pressure in the second channel.
[0013] Preferably, the sealing part includes two gaskets. An installation ring is provided on the side wall of the plug, and the two gaskets are sleeved on the plug and respectively closely adhere to the upper and lower sides of the installation ring.
[0014] By adopting the above technical solution, the setting of the gaskets can better achieve the sealing effect.
[0015] Preferably, limiting ring grooves are respectively formed on the side wall of the plug near the upper and lower sides of the installation ring, and the two gaskets are respectively nested in the two limiting ring grooves.
[0016] By adopting the above technical solution, the limiting ring grooves can further limit the position of the gaskets and reduce the probability of the gaskets falling off.
[0017] Preferably, convex rings are provided at the lower end of the through hole and the upper end of the first communication port, and the convex rings correspond to the gaskets in the up and down positions.
[0018] By adopting the above technical solution, the convex rings effectively increase the pressure by reducing the contact area with the gaskets, thereby improving the deformation effect when the gaskets contact the convex rings, and can further improve the sealing effect of the gaskets.
[0019] Preferably, an annular groove is formed on the top surface of the valve body around the opening of the communication cavity, and a sealing ring is provided in the annular groove. When the cover is connected to the housing, the cover presses the sealing ring.
[0020] By adopting the above technical solution, the sealing performance between the cover and the housing can be improved.
[0021] Preferably, the first communication port and the second communication port are at the same horizontal height, the water inlet is at the bottom end of the first channel, the water outlet is on the inner wall at the bottom end of the second channel, and the water inlet is lower than the water outlet.
[0022] By adopting the above technical solution, the accumulation of water at the bottom end of the second channel can be reduced by lowering the height of the water outlet.
[0023] The technical effects of the present utility model are mainly reflected in the following aspects:
[0024] 1. When the plug of the present utility model is damaged, only the cover body needs to be disassembled and the plug needs to be replaced. There are no complex parts and structures, and the replacement is simple.
[0025] 2. Since there is usually an overflow port inside the toilet of the present utility model, the position of the water outlet is lower than that of the overflow port. Therefore, even if the water backs up, it will not back into the second channel. However, the water backup will cause a change in the air pressure inside the second channel. Therefore, the ventilation port is provided to balance the air pressure inside the second channel.
[0026] 3. The convex ring of the present utility model effectively increases the pressure by reducing the contact area with the gasket, thereby improving the deformation effect when the gasket contacts the convex ring, and further improving the sealing effect of the gasket.

[0032] The following further describes the present application in detail with reference to the attached Figures 1-3 drawings to make the technical solution of the present application easier to understand and master.
[0033] An embodiment of the present application discloses an upward flushing component applied to a smart toilet.
[0034] Referring to Figures 1-3 , an upward flushing component applied to a smart toilet in this embodiment includes a valve body 1, a cover body 2 and a plug 3. The top end of the valve body 1 has a communication cavity 13, and the cover body 2 is fixedly connected to the top end of the valve body 1 by bolts to cover the communication cavity 13.
[0035] Referring to Figures 1-3 , a first channel 11 and a second channel 12 are vertically arranged in the valve body 1. The top ends of the first channel 11 and the second channel 12 communicate with the communication cavity 13 respectively, forming a first communication port 112 and a second communication port 122. An inlet 111 communicating with the first channel 11 and an outlet 121 communicating with the second channel 12 are also provided on the valve body 1.
[0036] Referring to Figures 1-3 , a through hole 21 is penetrated and opened at a position corresponding to the first communication port 112 on the cover body 2. The plug 3 is vertically sleeved in the through hole 21, and a sealing portion is provided at the lower end of the plug 3.
[0037] Referring to Figures 1-3 , wherein, when a negative pressure is formed in the first channel 11 relative to the communication cavity 13, the plug 3 slides downward and drives the sealing portion to block the first communication port 112. When there is an upward water flow in the first channel 11, the plug 3 slides upward and drives the sealing portion to block the through hole 21.
[0038] Referring to Figures 1-3 , during flushing, water enters the first channel 11 from the inlet 111, and the water pressure will drive the plug 3 to move upward. At this time, the plug 3 moves away from the first communication port 112, and water can enter the second channel 12 from the communication cavity 13 and then flow out from the outlet 121 to flush the smart toilet; when not flushing, the plug 3 blocks the first communication port 112 under the action of gravity, and the water in the second channel 12 cannot flow back to the first channel 11. At the same time, in the case of water cut-off or water pressure fluctuation, a negative pressure is generated in the first channel 11, which will play an adsorption role on the plug 3, and the plug 3 can closely adhere to the bottom wall of the communication cavity 13, playing a better blocking role; when the plug 3 is damaged, only need to disassemble the cover body 2 and replace the plug 3. There are no complex parts and structures, and the replacement is simple.
[0039] Referring to Figures 2-4 , the plug 3 is hollow, and ventilation openings 32 are provided on the side and top surfaces. Since there is usually an overflow port inside the toilet, the position of the outlet 121 is lower than the overflow port, so even if there is backwater, it will not back into the second channel 12. However, the backwater will cause a change in the air pressure in the second channel 12, so the setting of the ventilation openings 32 can balance the air pressure in the second channel 12.
[0040] Reference Figures 2-4 , the sealing part includes two gaskets 312. An installation ring 31 is provided on the side wall of the plug 3. The two gaskets 312 are sleeved on the plug 3 and are respectively close to the upper and lower sides of the installation ring 31. The setting of the gaskets 312 can better achieve the sealing effect.
[0041] Reference Figures 2-4 , limiting ring grooves 311 are respectively formed on the side wall of the plug 3 close to the upper and lower sides of the installation ring 31. The two gaskets 312 are respectively nested in the two limiting ring grooves 311. The limiting ring grooves 311 can further limit the position of the gaskets 312 and reduce the probability of the gaskets 312 falling off.
[0042] Reference Figure 2 and Figure 3 , convex rings 4 are provided at the lower end of the through hole 21 and the upper end of the first communication port 112. The convex rings 4 correspond to the gaskets 312 in the up and down positions. By reducing the contact area with the gaskets 312, the convex rings 4 can effectively increase the pressure, thereby improving the deformation effect when the gaskets 312 are in contact with the convex rings 4, and can further improve the sealing effect of the gaskets 312.
[0043] Reference Figure 2 and Figure 3 , when the lower gasket 312 abuts against the lower convex ring 4, the top surface of the fixing frame is flush with the top surface of the cover body 2. It can improve the aesthetics and at the same time facilitate the operator to judge whether the plug 3 is in normal use.
[0044] Reference Figure 1 and Figure 2 , an annular groove 22 is provided on the top surface of the valve body 1 around the opening of the communication cavity 13. A sealing ring 221 is provided in the annular groove 22. When the cover body 2 is connected to the housing, the cover body 2 presses the sealing ring 221. It can improve the sealing performance between the cover body 2 and the housing.
[0045] Reference Figure 1 and Figure 2 , the first communication port 112 and the second communication port 122 are at the same horizontal height. The water inlet 111 is located at the bottom end of the first channel 11, and the water outlet 121 is located on the inner wall of the bottom end of the second channel 12. The water inlet 111 is lower than the water outlet 121.
[0046] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
