Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to an anti-backflow water nozzle, and also discloses an automatic soymilk maker. Background Technology

[0002] Currently, high-end soymilk makers on the market can perform the processes of adding water, grinding, and cooking soymilk with a single button. A soymilk maker includes a water supply component, a grinding cup, a crushing component, and a heating device. The water supply component mainly uses a water pump to deliver water from the water tank to the grinding cup; that is, the water supply component's piping is connected to the grinding cup. To prevent soymilk from flowing back into the water supply piping, an anti-backflow structure needs to be installed at the outlet of the piping.

[0003] Chinese patent CN21541139U discloses a food processing machine with reliable water intake, including a machine body and a water supply component and a grinding component disposed on the machine body. The water supply component includes a water tank, a water pump and a water inlet pipe. The grinding component includes a grinding cup. The water tank, water pump and grinding cup are connected in sequence through the water inlet pipe. The side wall of the grinding cup is provided with a water inlet cap. The water inlet cap is connected to the water outlet end of the water inlet pipe. The water inlet cap includes an elastic valve plate that forms a water inlet slit. The elastic valve plate has a restoring elastic force to keep the water inlet slit in a closed state.

[0004] The aforementioned inlet cap is equipped with an elastic valve plate that forms an inlet slit. The problem is that, in order to ensure a closed state, the size of the inlet slit is limited to A and B, where A≤0.2mm and 0.5mm≤B≤3mm. Therefore, the flow rate of the inlet slit is very small, and the elastic valve plate is prone to losing its elasticity. The working pressure of the water pump needs to be adapted, which increases the cost.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a backflow prevention water nozzle with a reasonable structure, large flow rate, and low cost.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The present invention discloses an anti-backflow water tap, comprising a water outlet and a sealing element. The water outlet has a through hole; the sealing element has an insertion port, which gives the sealing element at least one free end; the water outlet has an insert, and the sealing element connects to the water outlet to seal one end of the through hole; the insert passes through the insertion port, so that the through hole is in a first state; the free end can deform relative to the insert, so that the through hole is in a second state.

[0008] The sealing element is installed on the water outlet, covering one end of the through hole, and the sealing element has a socket for mating and connecting with the through hole.

[0009] The plug is inserted into the socket, and the outer contour of the plug matches the shape of the socket. The plug and the socket together enable the through hole to be in the first state.

[0010] Specifically, the plug and the socket can fit together seamlessly, that is, the plug completely blocks the socket, so that the through hole is completely closed.

[0011] Alternatively, there may be a tiny gap between the plug and the socket, meaning the plug does not completely seal the socket. Air can enter the through-hole through the gap, but liquid is difficult to pass through, indicating that the through-hole is not completely sealed. However, the fit between the plug and the socket can largely prevent liquids such as soy milk from entering the through-hole and leaving residue.

[0012] The socket has at least one free end defined on the seal. The seal is made of a deformable material (rubber, silicone, etc.). When water pressure is applied to the other end of the through hole, the free end can be deformed relative to the plug, causing the shape of the socket to change. A through hole is formed between the socket and the plug, allowing one end of the through hole to communicate with the outside, i.e., the through hole is in the second state.

[0013] It is understood that the water outlet is connected to a water pump through a pipe, and the water pump can output water pressure to the through hole. There is a certain pressure in the pipe between the water outlet and the water pump. When the water pump is not turned on, the pressure is not enough to drive the free end to deform, so that the through hole is in the first state. The pressure in the through hole can also prevent liquids such as soy milk from seeping into the through hole.

[0014] In actual use, the water outlet is set in the working area of ​​the equipment. Due to splashing and other issues, a small amount of soy milk residue may form on the surface of the seal and in the gap between the plug and the connector. The water outlet can be sprayed with water by the water pump to wash away these residues.

[0015] The deformation of the free end is proportional to the water pressure inside the through hole, making it easier to match with a suitable water pump and control the water inlet speed. This invention has a simple structure, is easy to process, and can be applied to various household appliances, reducing production costs.

[0016] According to the above scheme, the through hole extends through both ends of the water outlet, thereby forming an inlet end and an outlet end on the water outlet. The plug is disposed on the end face of the outlet end, and the sealing element covers the end face of the outlet end, thereby allowing the plug to pass through the socket.

[0017] The water outlet is tubular, providing a through-hole, an inlet, and an outlet. The inlet is designed as a quick-connect fitting for easy pipe connection, while the outlet is a flat port for easy matching and installation of seals. Furthermore, the insert is an integral structure on the water outlet pipe opening; that is, a partial extension of the water outlet pipe wall creates an arc-shaped insert, corresponding to an arc-shaped opening in the socket, which facilitates manufacturing.

[0018] According to the above scheme, the projection of the inlet on the outlet end face is an arc, and the sealing part between the arc and its center constitutes a free end. The shape of the plug-in matches the shape of the inlet. As mentioned above, the arc-shaped inlet and plug-in are relatively easy to process. It can be understood that a free end can be divided on the sealing element for the inlet. Furthermore, by controlling the central angle corresponding to the arc-shaped inlet, the corresponding inlet length can be obtained. Of course, this inlet length corresponds to the radius specification of the sealing element. Similarly, the width of the inlet corresponds to the wall thickness of the plug-in.

[0019] According to the above scheme, the projection of the inlet on the end face of the outlet is irregular, and the shape of the plug-in is adapted to the shape of the inlet; the irregular shape is composed of several ray segments, and the ray segments have a unique intersection point. The sealing part between any two adjacent ray segments constitutes a free end. The usual implementation of the irregular shape is to make it into a "+" shape, so that four free ends can be formed on the sealing part. Of course, the plug-in is also cross-shaped. The flow rate of the inlet can be increased by using more free ends.

[0020] According to the above scheme, the sealing element is provided with a ring, which is fitted onto the water outlet so that the sealing element covers the end face of the water outlet. The sealing element and the ring are an integral structure, which can be manufactured by injection molding, making processing convenient. The ring is used to fit onto the water outlet so that the sealing element fits snugly against the end face of the water outlet for a seal.

[0021] According to the above scheme, the water outlet is provided with a fixing seat, the fixing seat is provided with several fixing holes, and the ring is provided with a limiting block. The fixing seat is provided with multiple fixing holes to install the water outlet onto the equipment. In order to prevent the ring and the seal from falling off, a limiting block is provided on the ring. The fixing seat can clamp and fix the limiting block during assembly.

[0022] An automatic soymilk maker includes a main unit, a mixing cup, and a water tank. The mixing cup is equipped with an anti-backflow water inlet, and the water tank is connected to a water pump, which is connected to a water inlet via a pipeline. The water pump can output water pressure to the water outlet. The deformation of the free end of the pump opens a through-hole to the mixing cup, thereby adding water to the mixing cup. When the water pump stops, the free end of the seal returns to its original position, closing the through-hole and preventing soymilk from flowing back into the water inlet and causing residue.

[0023] According to the above scheme, the side wall of the stirring cup is provided with an assembly port and a slot, the fixing seat is fixedly connected to the stirring cup, the water outlet end of the water outlet is inserted into the assembly port, and the ring is fitted between the water outlet end and the assembly port, so that the limiting block is embedded in the slot.

[0024] This utility model discloses an anti-backflow water tap, wherein the plug is inserted into the socket of the sealing element to form a free end. The plug blocks the socket, thus preventing the through hole from flowing back into the through hole and forming residue. Deformation of the free end can form a through hole between the plug and the socket, allowing the through hole to be connected. Increasing the pressure and changing the deformation of the free end can control the flow rate of the water tap. The overall structure is simple, easy to process, and can be applied to various household appliances, reducing production costs. Attached Figure Description

[0027] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-4 As shown, the present invention provides an anti-backflow water tap, comprising a water outlet 1 and a sealing element 2. The water outlet 1 has a through hole 11; the sealing element 2 has an insertion port 21, which gives the sealing element 2 at least one free end 22; the water outlet 1 has an insert 12, and the sealing element 2 connects to the water outlet 1 to seal one end of the through hole 11; the insert 12 passes through the insertion port 21, so that the through hole 11 is in a first state; the free end 22 can deform relative to the insert 12, so that the through hole 11 is in a second state.

[0029] The sealing element 2 is installed on the water outlet 1, and the sealing element 2 covers one end of the through hole 11. The sealing element 2 is provided with a socket 21 to connect with the through hole 11.

[0030] The plug 12 is inserted into the socket 21, and the outer contour of the plug 12 matches the shape of the socket 21. The plug 12 cooperates with the socket 21 to make the through hole 11 in the first state.

[0031] Specifically, the plug-in 12 and the socket 21 can be seamlessly connected, that is, the plug-in 12 completely blocks the socket 21, so that the through hole 11 is completely closed.

[0032] Alternatively, there may be a small gap between the plug 12 and the socket 21, meaning the plug 12 does not completely seal the socket 21. Air can enter the through hole 11 through the gap, but liquid is difficult to pass through, meaning the through hole 11 is not completely sealed. However, the cooperation between the plug 12 and the socket 21 can largely prevent liquids such as soy milk from entering the through hole 11 and forming residue.

[0033] The socket 21 has at least one free end 22 divided on the sealing member 2. The sealing member 2 is made of a deformable material (rubber, silicone, etc.). When water pressure is applied to the other end of the through hole 11, the free end 22 can be pushed to deform relative to the plug-in 12, so that the shape of the socket 21 changes and a through hole is formed between the socket 21 and the plug-in 12, so that one end of the through hole 11 is connected to the outside, that is, the through hole 11 is in the second state.

[0034] It is understood that the water outlet 1 is connected to the water pump 33 through a pipeline. The water pump 33 can output water pressure to the through hole 11. There is a certain pressure in the pipeline between the water outlet 1 and the water pump 33. When the water pump 33 is not turned on, the pressure is insufficient to drive the free end 22 to deform, so that the through hole 11 is in the first state. The pressure in the through hole 11 can also prevent liquids such as soy milk from seeping into the through hole 11.

[0035] In actual use, the water outlet 1 is set in the working area of ​​the equipment. Due to splashing and other issues, a small amount of soy milk residue is formed on the surface of the seal 2 and in the gap between the inlet 21 and the plug 12. The water outlet 1 can be sprayed with water by the water pump 33 to wash away these residues.

[0036] It is understood that the deformation of the free end 22 is proportional to the water pressure in the through hole 11, making it easier to match with a suitable water pump 33 and control the water inlet speed. This utility model has a simple structure, is easy to process, and can be applied to various household appliances, reducing production costs.

[0037] The through hole 11 passes through both ends of the water outlet 1, thereby forming an inlet end 101 and an outlet end 102 on the water outlet 1. The plug 12 is disposed on the end face of the outlet end 102. The sealing member 2 covers the end face of the outlet end 102, thereby allowing the plug 12 to pass through the socket 21.

[0038] The water outlet 1 is tubular, providing a through hole 11, an inlet end 101, and an outlet end 102. The inlet end 101 is designed as a quick-connect fitting for easy pipe connection, and the outlet end 102 is designed as a flat port for easy matching and installation of the sealing element 2. Furthermore, the insert 12 is an integral structure on the opening of the water outlet 1; that is, a partial extension of the pipe wall of the water outlet 1 can form an arc-shaped insert 12. Correspondingly, the insertion port 21 is made into an arc-shaped opening, which is relatively easy to manufacture.

[0039] Specifically, the projection of the inlet 21 onto the end face of the outlet 102 is an arc, and the portion of the sealing element 2 between the arc and its center forms a free end 22. The shape of the insert 12 is adapted to the shape of the inlet 21. As mentioned above, the arc-shaped inlet 21 and insert 12 are relatively easy to manufacture. It can be understood that a free end 22 can be divided on the sealing element 2 from the inlet 21. Furthermore, by controlling the central angle corresponding to the arc-shaped inlet 21, the corresponding length of the inlet 21 can be obtained. Of course, the length of the inlet 21 corresponds to the radius specification of the sealing element 2. Similarly, the width of the inlet 21 corresponds to the wall thickness of the insert 12.

[0040] In other embodiments, the projection of the inlet 21 onto the end face of the outlet 102 is irregular, and the insert 12 is adapted to the shape of the inlet 21. The irregular shape is composed of several ray segments, each ray segment having a unique intersection point, and the sealing part 2 between any two adjacent ray segments constitutes a free end 22. The common implementation of the irregular shape is to make it into a cross shape, thereby forming four free ends 22 on the sealing part 2. Of course, the insert 12 is also cross-shaped. The flow rate of the inlet 21 can be increased by using more free ends 22.

[0041] The sealing element 2 is provided with a ring 23, which is fitted onto the water outlet 1 so that the sealing element 2 covers the end face of the water outlet 102. The sealing element 2 and the ring 23 are an integral structure and can be manufactured by injection molding, which is convenient to process. The ring 23 is used to fit onto the water outlet 1 so that the sealing element 2 fits and seals against the end face of the water outlet 102.

[0042] The water outlet 1 is provided with a fixing seat 13, and the fixing seat 13 is provided with several fixing holes 14. The ring 23 is provided with a limiting block 24. The fixing seat 13 is provided with multiple fixing holes 14 to install the water outlet 1 onto the equipment. In order to prevent the ring 23 and the seal 2 from falling off, the limiting block 24 is provided on the ring 23. The fixing seat 13 can clamp and fix the limiting block 24 during assembly.

[0043] like Figure 5-6As shown, an automatic soymilk maker includes a main unit 3, a mixing cup 31, and a water tank 32. The mixing cup 31 is equipped with an anti-backflow water inlet. A water pump 33 is connected to the water tank 32, and the water pump 33 is connected to the water inlet 101 via a pipeline. The water pump 33 can output water pressure to the water outlet 1. The deformation of the free end 22 causes the through hole 11 to connect to the mixing cup 31, thereby adding water to the mixing cup 31. When the water pump 33 stops, the free end 22 on the sealing member 2 returns to its original position and closes the through hole 11, preventing soymilk in the mixing cup 31 from flowing back into the water inlet and causing residue.

[0044] The side wall of the stirring cup 31 is provided with an assembly port 34 and a slot. The fixing seat 13 is fixedly connected to the stirring cup 31. The water outlet 102 of the water outlet 1 passes through the assembly port 34, and the ring 23 is fitted between the water outlet 102 and the assembly port 34, so that the limiting block 24 is embedded in the slot.

[0045] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
