Description

Technical Field

[0001] This application relates to the technical field of sanitary devices, and particularly to a liquid mixing device and a sanitary equipment. Background Art

[0002] In order to improve people's living standards, intelligent toilets with a foam shield function have emerged on the market. The principle is that the foam layer generated by a foaming device covers the water seal surface of the toilet. When using the intelligent toilet, it can play a good role in splash prevention, odor isolation, wall lubrication, and sterilization.

[0003] In related technologies, there are two common foaming methods. One is to introduce water and a foaming agent into the same mixing chamber. While introducing water, the foaming agent is added in small amounts multiple times for mixing, and then the mixed liquid is extruded from the mixing chamber by water pressure to form a foam shield. Due to the mixing form of small amounts multiple times, in order not to cause waste of the foaming agent, the amount of foaming agent introduced each time is required to be extremely small. This method has high requirements for the accuracy and stability of the foaming agent delivery pump and high costs. The other is to pump a certain amount of foaming agent into the mixing chamber at one time, and then the mixed liquid is extruded from the mixing chamber by continuous water flow to form a foam shield. In this way, since the foaming agent is only pumped in once and the volume of the mixing chamber is generally small, the water flow is very likely to quickly carry away the internal foaming agent when flowing through the mixing chamber, resulting in a phenomenon that the concentration of the foaming agent in the first half is high and the concentration in the second half is low when the mixed liquid is output, leading to poor foaming effect. In order to avoid the above problems, it is necessary to increase the dosage of the foaming agent pumped in once, resulting in waste of the foaming agent. Content of the Utility Model

[0004] In view of this, this application provides a liquid mixing device and a sanitary equipment to solve or improve the problem of insufficient utilization of the foaming agent and high costs.

[0005] In the first aspect, this application provides a liquid mixing device, including:

[0006] A cavity, provided with a liquid inlet hole and a liquid outlet hole communicating with its inner cavity;

[0007] A first partition, connected to the inner wall of the cavity, separating the inner cavity of the cavity into a flow-through cavity and a mixing cavity for accommodating the foaming agent mixed liquid;

[0008] A second partition, arranged on the inner wall of the flow-through cavity, separating the flow-through cavity into a liquid inlet cavity and a liquid outlet cavity. The liquid inlet cavity is provided with a liquid inlet, the liquid inlet is communicated with the liquid inlet hole, the liquid outlet cavity is provided with a liquid outlet, the liquid outlet is communicated with the liquid outlet hole. A communication port communicating the liquid inlet cavity and the liquid outlet cavity is opened on the second partition. At least one first mixing hole communicating with the mixing cavity is opened on the side wall of the liquid inlet cavity, and at least one second mixing hole communicating with the mixing cavity is opened on the side wall of the liquid outlet cavity.

[0009] Beneficial effects: The foaming agent mixture is injected into the liquid inlet cavity through the liquid inlet hole. The foaming agent mixture fills the liquid inlet cavity, the liquid outlet cavity, and the mixing cavity through the first mixing hole, the second mixing hole, and the communication port. When foam needs to be produced, an external water source is connected to the liquid inlet hole. Under the water pressure of the external water source, the water flow quickly passes through the liquid inlet cavity, the communication port, and the liquid outlet cavity and sprays out from the liquid outlet hole. According to Bernoulli's principle, the pressure of the fluid is low where the flow rate is high. Therefore, the pressure in the liquid inlet cavity and the liquid outlet cavity is less than the pressure in the mixing cavity. Thus, the foaming agent mixture in the mixing cavity is sucked into the liquid inlet cavity and the liquid outlet cavity through the first mixing hole and the second mixing hole. When the foaming agent mixture passes through the first mixing hole and the second mixing hole, it contacts the high-speed water flow, and the foaming agent mixture can quickly mix with the water flow, improving the mixing effect and facilitating the generation of foam. Using Bernoulli's principle to suck out the foaming agent mixture in the mixing cavity can extend the service life of the foaming agent mixture, and through the impact of the high-speed water flow and the foaming agent mixture, the mixing efficiency of the foaming agent mixture and the water flow can be improved; the water flow first passes through the first mixing hole. When the foaming agent mixture in the mixing cavity is transported from the first mixing hole into the liquid inlet cavity, it is mixed once. When the foaming agent mixture in the mixing cavity is transported from the second mixing hole into the liquid outlet cavity, it is mixed again, improving the mixing efficiency.

[0010] In an optional embodiment, a flow gap is provided between the bottom of the first partition plate and the bottom of the cavity. The liquid inlet cavity and the liquid outlet cavity communicate with the mixing cavity through the flow gap.

[0011] In an optional embodiment, the cavity includes a receiving groove and a cover plate. The cover plate is sealingly connected to the notch of the receiving groove. The cover plate is provided with a liquid inlet hole, a liquid outlet hole, and an additive hole. One end of the first partition plate is connected to the bottom of the cover plate, and a flow gap is provided between the other end of the first partition plate and the bottom of the receiving groove. The additive hole communicates with the mixing cavity.

[0012] In an optional embodiment, the first partition plate is of a cylindrical structure. The first end of the first partition plate is connected to the cover plate. A guide plate is provided at the bottom of the receiving groove corresponding to the first partition plate. A guide gap is provided between the outer wall of the first partition plate and the inner wall of the guide plate. The guide gap communicates with the flow gap and the mixing cavity.

[0015] In an optional embodiment, a positioning protrusion is provided on the bottom surface of the cover plate. The outer side wall of the positioning protrusion is in sealing contact with the inner side wall of the receiving groove.

[0016] In an alternative embodiment, both the first mixing hole and the second mixing hole are formed in the first partition plate. The first mixing hole is arranged close to the liquid inlet hole, and the second mixing hole is arranged close to the liquid outlet hole.

Detailed implementation manners

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0035] The following combines with Figures 1 to 12 , to describe the embodiments of the present application.

[0036] According to an embodiment of the present application, on the one hand, a liquid mixing device is provided, including:

[0037] A cavity 1, provided with a liquid inlet hole 2 and a liquid outlet hole 3 communicating with its inner cavity;

[0038] A first partition plate 4, connected to the inner wall of the cavity 1, separating the inner cavity of the cavity 1 into a flow cavity and a mixing cavity 5 for accommodating a foaming agent mixture;

[0039] The second partition plate 6 is arranged on the inner wall of the flow cavity, dividing the flow cavity into a liquid inlet cavity 7 and a liquid outlet cavity 8. The liquid inlet cavity 7 is provided with a liquid inlet, and the liquid inlet is communicated with the liquid inlet hole 2. The liquid outlet cavity 8 is provided with a liquid outlet, and the liquid outlet is communicated with the liquid outlet hole 3. A communication port 9 communicating the liquid inlet cavity 7 and the liquid outlet cavity 8 is opened on the second partition plate 6. At least one first mixing hole 10 communicating with the mixing cavity 5 is opened on the side wall of the liquid inlet cavity 7, and at least one second mixing hole 11 communicating with the mixing cavity 5 is opened on the side wall of the liquid outlet cavity 8.

[0040] The foaming agent mixture is injected into the liquid inlet cavity 7 through the liquid inlet hole 2. The foaming agent mixture fills the liquid inlet cavity 7, the liquid outlet cavity 8 and the mixing cavity 5 through the first mixing hole 10, the second mixing hole 11 and the communication port 9. When foam needs to be produced, an external water source is connected to the liquid inlet hole 2. Under the water pressure of the external water source, the water flow quickly passes through the liquid inlet cavity 7, the communication port 9, the liquid outlet cavity 8 and is ejected from the liquid outlet hole 3. According to Bernoulli's principle, the pressure of the fluid is low where the flow rate is high. Therefore, the pressure in the liquid inlet cavity 7 and the liquid outlet cavity 8 is lower than the pressure in the mixing cavity 5. Thus, the foaming agent mixture in the mixing cavity 5 is sucked into the liquid inlet cavity 7 and the liquid outlet cavity 8 through the first mixing hole 10 and the second mixing hole 11. When the foaming agent mixture passes through the first mixing hole 10 and the second mixing hole 11, it contacts the high-speed water flow, and the foaming agent mixture can be quickly mixed with the water flow, improving the mixing effect and facilitating the generation of foam. Using Bernoulli's principle to suck out the foaming agent mixture in the mixing cavity 5 can extend the service life of the foaming agent mixture, and through the impact of the high-speed water flow and the foaming agent mixture, the mixing efficiency of the foaming agent mixture and the water flow can be improved; the water flow passes through the first mixing hole 10 first. When the foaming agent mixture in the mixing cavity 5 is transported from the first mixing hole 10 into the liquid inlet cavity 7, a first mixing is carried out. When the foaming agent mixture in the mixing cavity 5 is transported from the second mixing hole 11 into the liquid outlet cavity 8, a second mixing is carried out again, improving the mixing efficiency.

[0041] In a specific embodiment, as Figure 6 and Figure 8 shown, the water flow enters the liquid inlet cavity 7 from the liquid inlet hole 2. According to Bernoulli's principle, the pressure in the liquid inlet cavity 7 is lower than the pressure in the mixing cavity 5. The foaming agent mixture enters the liquid inlet cavity 7 along the primary mixing route 29 for primary mixing; when the water flow enters the liquid outlet cavity 8 and is ejected from the liquid outlet hole 3, the pressure in the liquid outlet cavity 8 is lower than the pressure in the mixing cavity 5. The foaming agent mixture enters the liquid outlet cavity 8 along the tertiary mixing route 31 for tertiary mixing.

[0042] In a specific embodiment, a plurality of first mixing holes 10 are arranged at intervals along the water flow direction on the side wall of the liquid inlet cavity 7, and a plurality of second mixing holes 11 are arranged at intervals along the water flow direction on the side wall of the liquid outlet cavity 8 to improve the mixing effect.

[0043] In one embodiment, a flow-through gap 12 is provided between the bottom of the first partition plate 4 and the bottom of the cavity 1, and the liquid inlet cavity 7 and the liquid outlet cavity 8 communicate with the mixing cavity 5 through the flow-through gap 12. The flow-through gap 12 can communicate the mixing cavity 5 with the liquid inlet cavity 7 and the liquid outlet cavity 8 respectively. When water flows into the liquid inlet cavity 7 and passes through the communication port 9 into the liquid outlet cavity 8, according to Bernoulli's principle, the flow rate of the water at the communication port 9 is fast, the pressure around the communication port 9 decreases, and the foaming agent mixture in the mixing cavity 5 is sucked into the liquid inlet cavity 7 and the liquid outlet cavity 8 through the flow-through gap 12. When the foaming agent mixture enters the liquid inlet cavity 7 and the liquid outlet cavity 8, it collides with the high-speed water flow, performing secondary mixing and improving the mixing effect.

[0044] In a specific embodiment, as Figure 7 and Figure 9 shown, the foaming agent mixture enters the liquid inlet cavity 7 and the liquid outlet cavity 8 along the secondary mixing route 30, improving the mixing effect.

[0045] More specifically, as Figure 10 shown, the water flow enters the liquid inlet cavity 7 from the liquid inlet hole 2, passes through the communication port 9 into the liquid outlet cavity 8, and sprays out through the liquid outlet hole 3. During this process, the foaming agent mixture undergoes three-stage mixing. The foaming agent mixture completes the first-stage mixing when entering the liquid inlet cavity 7 through the first mixing hole 10, completes the second-stage mixing when entering the liquid inlet cavity 7 and the liquid outlet cavity 8 through the flow-through gap 12, and completes the third-stage mixing when entering the liquid outlet cavity 8 through the second mixing hole 11.

[0046] In one embodiment, the cavity 1 includes a receiving groove 101 and a cover plate 102. The cover plate 102 is sealingly connected to the notch of the receiving groove 101. The cover plate 102 is provided with a liquid inlet hole 2, a liquid outlet hole 3 and an additive hole 13. One end of the first partition plate 4 is connected to the bottom of the cover plate 102, and a flow-through gap 12 is provided between the other end of the first partition plate 4 and the bottom of the receiving groove 101. The additive hole 13 communicates with the mixing cavity 5.

[0047] In a specific embodiment, as Figure 5 shown, the foaming agent mixture is added to the liquid inlet cavity 7, the liquid outlet cavity 8 and the mixing cavity 5 along the foaming agent mixture adding route 32 through the additive hole 13, making the filling more convenient.

[0048] More specifically, the liquid inlet pipe 20, the liquid outlet pipe 21 and the additive pipe 22 are respectively fixed to the cover plate 102 corresponding to the liquid inlet hole 2, the liquid outlet hole 3 and the additive hole 13.

[0049] In a specific embodiment, as Figure 11 and Figure 12As shown in the figure, a plurality of connecting plates 23 extend outward from the edge of the cover plate 102. Each connecting plate 23 is provided with a connecting hole 24. Corresponding to the plurality of connecting plates 23, a plurality of connecting members 25 are connected to the end side wall of the receiving groove 101. Each connecting member 25 is provided with a threaded hole 26 corresponding to the connecting hole 24. A bolt passes through the connecting hole 24 and is screwed into the corresponding threaded hole 26 to fixedly connect the cover plate 102 and the receiving groove 101.

[0050] More specifically, the connecting member 25 is a connecting block or a connecting column, and the connecting block and the connecting column are provided with threaded holes 26 corresponding to the connecting holes 24.

[0051] In one embodiment, the first partition 4 is of a cylindrical structure. The first end of the first partition 4 is connected to the cover plate 102. A flow guide plate 14 is provided at the bottom of the receiving groove 101 corresponding to the first partition 4. A flow guide gap 15 is provided between the outer wall of the first partition 4 and the inner wall of the flow guide plate 14. The flow guide gap 15 is communicated with the flow through gap 12 and the mixing chamber 5. The first end of the first partition 4 is connected to the cover plate 102. A mixing chamber 5 is formed between the outer wall of the first partition 4 and the inner wall of the receiving groove 101. The structure of the mixing chamber 5 is an annular chamber, which is convenient for communicating with the liquid inlet chamber 7 and the liquid outlet chamber 8. A flow guide gap 15 is formed between the flow guide plate 14 and the first partition 4. When the foaming agent mixture enters the liquid inlet chamber 7 and the liquid outlet chamber 8 along the secondary mixing route 30, the flowing path of the foaming agent mixture is extended, and the disorder degree of the foaming agent mixture during flow is increased, improving the mixing effect.

[0052] In a specific embodiment, the first partition 4 is a structural member with a channel, and the cross-section of the corresponding flow guide plate 14 matches the cross-section of the first partition 4. A flow guide gap 15 is formed between one end side wall of the first partition 4 and the inner wall of the flow guide plate 14.

[0053] Further illustration is that the cross-section of the first partition 4 can be of various shapes, and the cross-section of the flow guide plate 14 matches the cross-section of the first partition 4, so that a flow guide gap 15 is formed between the outer wall of the first partition 4 and the inner wall of the flow guide plate 14.

[0054] Even further illustration is that the first partition 4 is of a cylindrical structure, and the corresponding flow guide plate 14 is arranged as an annular protrusion. A flow guide gap 15 is formed between the outer wall of the first partition 4 and the inner wall of the annular protrusion.

[0055] In a specific embodiment, as Figure 11 shown, it further includes a plurality of reinforcing plates 27. One side of the plurality of reinforcing plates 27 is connected to the bottom surface of the cover plate 102, and the other side is connected to the outer wall of the first partition 4, which is convenient for fixing the first partition 4 on the cover plate 102.

[0056] More specifically, the reinforcing plate 27 is a right-angled triangular plate. The first right-angled side of the right-angled triangular plate is fixedly connected to the bottom surface of the cover plate 102, and the second right-angled side is fixedly connected to the outer wall of the first partition plate 4. The fixing method can be welding, bonding and other fixing methods.

[0057] In a specific embodiment, the first end of the first partition plate 4 is hermetically connected to the bottom surface of the cover plate 102, and a sealant can be provided at the connection.

[0058] In a specific embodiment, the top end of the second partition plate 6 is hermetically connected to the bottom plate of the cover plate 102, and the two side ends are hermetically connected to the inner wall of the first partition plate 4. The length of the second partition plate 6 along the axial direction of the first partition plate 4 is less than the length of the first partition plate 4. A communication port 9 is formed between the second partition plate 6 and the bottom of the receiving groove 101.

[0059] In one embodiment, at least one notch 16 is formed on the side wall of the flow guide plate 14. The notch 16 communicates with the flow guide gap 15 and the mixing chamber 5. When the foaming agent mixture enters the liquid inlet chamber 7 and the liquid outlet chamber 8 along the secondary mixing route 30, the foaming agent mixture enters the flow guide gap 15 from the notch 16 and flows a certain distance along the flow guide gap 15, extending the flow path of the foaming agent mixture and increasing the disorder degree of the foaming agent mixture during circulation, thereby improving the mixing effect.

[0060] Furthermore, a plurality of notches 16 are provided on the side wall of the flow guide plate 14 to improve the mixing efficiency.

[0061] In a specific embodiment, a plurality of reinforcing plates 28 are further included. The reinforcing plates 28 are located in the mixing chamber 5. One side of the reinforcing plates 28 is fixedly connected to the inner wall of the receiving groove 101, and the other side end is fixedly connected to the flow guide plate 14.

[0062] In a specific embodiment, the reinforcing plate 28 is an L-shaped plate. The longitudinal plate of the L-shaped plate is fixedly connected to the inner wall of the receiving groove 101, and the transverse plate is fixedly connected to the bottom of the receiving groove 101. An arc-shaped plate 33 is fixedly connected to one end of the transverse plate. A plurality of arc-shaped plates 33 are arranged at equal angular intervals to form the flow guide plate 14. Two arc-shaped plates 33 are arranged at intervals, and a notch 16 is formed therebetween.

[0063] In one embodiment, as Figure 3 、 Figure 11 and Figure 12 shown, a sealing groove 17 is formed at the end of the notch of the receiving groove 101, and a sealing protrusion 18 is provided on the bottom surface of the cover plate 102. The sealing protrusion 18 is inserted into the sealing groove 17.

[0064] Furthermore, the cover plate 102 can be sealed with the notch of the receiving groove 101 by ultrasonic welding; or a soft rubber pad seal or an O-ring seal can be provided at the bottom of the sealing groove 17.

[0065] In one embodiment, a positioning protrusion 19 is provided on the bottom surface of the cover plate 102, and the outer side wall of the positioning protrusion 19 is sealingly connected to the inner side wall of the receiving groove 101. The sealing protrusion 18 is sealingly connected to the sealing groove 17, and the positioning protrusion 19 is sealingly connected to the notch of the receiving groove 101, achieving double sealing and improving the sealing effect.

[0066] In a specific embodiment, as Figure 11 and Figure 12 shown, the receiving groove 101 can be a circular groove, and both the sealing protrusion 18 and the positioning protrusion 19 are annular sealing protrusions.

[0067] In one embodiment, both the first mixing hole 10 and the second mixing hole 11 are formed in the first partition plate 4. The first mixing hole 10 is arranged close to the liquid inlet hole 2, and the second mixing hole 11 is arranged close to the liquid outlet hole 3. When the first mixing hole 10 is arranged close to the liquid inlet hole 2, the water flow velocity at the liquid inlet hole 2 is high. Therefore, the pressure difference at both ends of the first mixing hole 10 is large, facilitating the suction of the foaming agent mixture into the liquid inlet chamber 7; similarly, the water flow velocity at the liquid outlet hole 3 is high, and the pressure difference at both ends of the second mixing hole 11 is large, facilitating the suction of the foaming agent mixture into the liquid outlet chamber 8.

[0068] In one embodiment, the sum of the volumes of the liquid inlet chamber 7 and the liquid outlet chamber 8 is smaller than the volume of the mixing chamber 5. The main function of the mixing chamber 5 is to store the foaming agent mixture, and the foaming agent mixture is slowly released through the pressure difference between the liquid inlet chamber 7 and the mixing chamber 5 and the pressure difference between the liquid outlet chamber 8 and the mixing chamber 5, extending the service life.

[0069] In a specific embodiment, the volume ratio of the receiving groove 101 to the flow-through chamber is 6:5.

[0070] According to an embodiment of the present application, on the other hand, a sanitary ware device including a liquid mixing device is also provided.

[0071] The sanitary ware device can be a smart toilet or a spraying device.

[0072] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations all fall within the scope defined by the appended claims of the present application.
