Description

Technical Field

[0001] The present invention relates to the technical field of sanitary ware, and particularly relates to a cleaning system for a toilet. Background Art

[0002] At present, a device called a foam shield has emerged in the market of intelligent toilets, which can effectively solve the problems of splashing water and deodorization. However, in existing foam shield devices, liquid mixing and foaming are carried out in different devices respectively, resulting in problems such as too large volume, cumbersome structural composition, and too high cost. Moreover, a large amount of special foaming liquid is required to continuously foam. The cost of the required special foaming liquid is high, and it is inconvenient to purchase and store, and the foaming liquid needs to be added frequently.

[0003] Due to the limited internal space of the intelligent toilet and the need to install other cleaning and other functional devices at the same time, it is very difficult to simply add the existing foam shield to the general intelligent toilet model, resulting in difficulty in miniaturizing the overall intelligent toilet. Even if the problem of miniaturization is not considered and the function of the foam shield is added to the intelligent toilet, there will also be a problem that the foaming liquid is quickly consumed and the special foaming liquid needs to be added frequently. Eventually, due to the trouble of changing the liquid and high cost, the use experience of consumers for the intelligent toilet is seriously reduced. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a cleaning system for a toilet with a simple and compact structure, low cost, and easy to control.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A cleaning system for a toilet includes a water supply component, a gas supply component, a foaming component, a flow dividing valve, and a liquid storage box for storing foaming liquid. The flow dividing valve has a water and gas inlet, a foaming outlet, and more than one cleaning outlet. The water supply component and the gas supply component are both connected to the water and gas inlet. The foaming outlet is connected to the foaming component through a water and gas pipeline. The liquid storage box is connected to the foaming component through a liquid pumping component.

[0007] As a further improvement of the above technical solution:

[0008] The water supply component and the gas supply component are connected to the water and gas inlet through a three-way valve. The water supply component includes a pressure water source, and the gas supply component includes an air pump. The outlets of the pressure water source and the air pump are respectively connected to two valve ports of the three-way valve, and the other valve port of the three-way valve is connected to the water and gas inlet.

[0009] The cleaning outlets of the flow dividing valve include a feminine wash outlet, a buttocks wash outlet, and a self-cleaning outlet; the flow dividing valve includes a valve body, a valve disc, and a rotary driving member. The valve body has a water inlet cavity communicating with the water and air inlet. On one inner wall of the water inlet cavity, there are a first flow dividing port communicating with the feminine wash outlet, a second flow dividing port communicating with the buttocks wash outlet, a third flow dividing port communicating with the self-cleaning outlet, and a fourth flow dividing port communicating with the foaming outlet. The valve disc is arranged in contact with the inner wall of the water inlet cavity, and the valve disc is provided with a communication port that can selectively communicate the water inlet cavity with the first flow dividing port, the second flow dividing port, the third flow dividing port, and the fourth flow dividing port when the valve disc rotates. The rotary driving member is installed on the valve body and connected to the valve disc to drive the valve disc to rotate.

[0010] The foaming assembly includes a foaming box having a foaming inner cavity. A microporous foaming member is installed in the foaming inner cavity. The microporous foaming member divides the inner cavity into a liquid mixing chamber and a bubble discharge chamber. The foaming box is further provided with a water, gas, and liquid inlet communicating with the liquid mixing chamber and a bubble outlet communicating with the bubble discharge chamber. The water, gas, and liquid inlet is connected to the liquid pumping assembly and the foaming outlet.

[0011] The bubble discharge chamber is located above the liquid mixing chamber.

[0012] The microporous foaming member has a recessed portion, and the recessed portion and the cavity wall of the foaming inner cavity enclose the liquid mixing chamber.

[0013] The foaming box includes a box body and a sealing cover. The box body has a cavity with one end open. The sealing cover is detachably connected to the box body through fasteners and closes the opening of the cavity to form the foaming inner cavity.

[0014] The sealing cover has more than one pressing rod portion, and the microporous foaming member is pressed between the inner wall of the foaming inner cavity and more than one pressing rod portion.

[0015] The liquid pumping assembly includes a liquid pumping pump. The inlet of the liquid pumping pump is communicated with a liquid storage box through a liquid inlet pipe, and the outlet of the liquid pumping pump is communicated with the water, gas, and liquid inlet through a liquid outlet pipe.

[0016] The foaming box further has a pump accommodating cavity. The liquid pumping pump is installed in the pump accommodating cavity, and a shock-absorbing member is provided between the liquid pumping pump and the inner wall of the pump accommodating cavity.

[0017] Compared with the prior art, the advantages of the present invention are as follows: The cleaning system for a toilet of the present invention only sets one water supply assembly and one air supply assembly. Combining with the flow dividing valve can realize the water supply required for the cleaning function and supply the water, gas, and mixture to the foaming assembly, so that the foaming assembly does not need to separately set up a device for generating and supplying the water, gas, and mixture. It has the advantages of simple and compact structure, low cost, and easy control. Description of the Drawings

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] As Figures 1 to 3As shown in the figure, the cleaning system for a toilet of this embodiment includes a water supply component 1, a gas supply component 2, a foaming component 3, a flow dividing valve 4, and a liquid storage box 5 for storing foaming liquid. The flow dividing valve 4 has a water and gas inlet 41, a foaming outlet 45, and more than one cleaning outlet. The water supply component 1 and the gas supply component 2 are both connected to the water and gas inlet 41. The foaming outlet 45 is connected to the foaming component 3 through a water and gas pipeline 101. The liquid storage box 5 is connected to the foaming component 3 through a liquid pumping component 7. This cleaning system only sets one water supply component 1 and one set of gas supply components 2. Combining with the flow dividing valve 4 can realize the water supply required for the cleaning function and supply the water and gas mixture to the foaming component 3, so that the foaming component 3 does not need to set up a device for generating and supplying the water and gas mixture separately. It has the advantages of simple and compact structure, low cost, and easy control.

[0029] In this cleaning system, the water supply component 1 and the gas supply component 2 in it can be replaced by the original air pump and water supply waterway of the existing intelligent toilet.

[0030] In this embodiment, the water supply component 1 and the gas supply component 2 are connected to the water and gas inlet 41 through a three-way valve 6. The water supply component 1 includes a pressure water source, and the gas supply component 2 includes an air pump 21. The outlets of the pressure water source and the air pump 21 are respectively communicated with two valve ports of the three-way valve 6, and the other valve port of the three-way valve 6 is communicated with the water and gas inlet 41. When the air pump 21 is not turned on, the water from the pressure water source is sent to the flow dividing valve 4 through the three-way valve 6 and is distributed and output by the flow dividing valve 4. When the air pump 21 is turned on, the air pump 21 pumps air to the three-way valve 6 and mixes it with the water from the pressure water source to form a water and gas mixture, which is then sent to the flow dividing valve 4 and is distributed and output by the flow dividing valve 4. The above three-way valve 6 adopts an existing conventional valve, and the pressure water source can be a tap water pipeline or a combination of a water tank and a water pump. The above combination can supply water or the water and gas mixture separately according to needs, and only need to open or close the air pump 21 correspondingly. It has the advantages of simple structure, easy control, and stable and reliable operation. In other embodiments, the water supply component 1 and the gas supply component 2 can be separately connected to the water and gas inlet 41.

[0031] In this embodiment, the cleaning outlets of the flow dividing valve 4 include a feminine wash outlet 42, a posterior wash outlet 43, and a self-cleaning outlet 44, which can realize the water supply for feminine wash, posterior wash, and self-cleaning. As Figure 7As shown in the figure, the flow dividing valve 4 includes a valve body 401, a valve disc 402 and a rotary driving member 403. The valve body 401 has a water inlet cavity communicating with the water and air inlet 41. On one inner wall of the water inlet cavity, there are provided a first flow dividing port communicating with the feminine wash outlet 42, a second flow dividing port communicating with the hip wash outlet 43, a third flow dividing port communicating with the self-cleaning outlet 44 and a fourth flow dividing port communicating with the foaming outlet 45. The valve disc 402 is arranged in contact with the inner wall of the water inlet cavity, and the valve disc 402 is provided with a communication port 4021 which can selectively communicate the water inlet cavity with the first flow dividing port, the second flow dividing port, the third flow dividing port and the fourth flow dividing port when the valve disc 402 rotates. The rotary driving member 403 is installed on the valve body 401 and connected to the valve disc 402 to drive the valve disc 402 to rotate. When the rotary driving member 403 drives the valve disc 402 to rotate, the water inlet cavity can be selectively communicated with the first flow dividing port, the second flow dividing port, the third flow dividing port and the fourth flow dividing port, so as to lead water or a water-gas mixture to the feminine wash outlet 42, the hip wash outlet 43, the self-cleaning outlet 44 and the foaming outlet 45. The structure of the flow dividing valve 4 is simple, with low cost and easy to control. In other embodiments, the flow dividing valve 4 can also adopt other existing forms of valves with one inlet and four outlets, and the inlet can selectively communicate with the four outlets. The cleaning outlets of the flow dividing valve 4 can also be provided with at least one of the feminine wash outlet 42, the hip wash outlet 43 and the self-cleaning outlet 44, or additional cleaning outlets with other functions can be added. Correspondingly, the number of outlets of the flow dividing valve 4 is the same as the number of cleaning outlets.

[0032] In this embodiment, as Figures 4 to 6 shown, the foaming assembly 3 includes a foaming box 31 having a foaming inner cavity. A microporous foaming member 32 is installed in the foaming inner cavity. The microporous foaming member 32 divides the inner cavity into a liquid mixing chamber 33 and a bubble discharging chamber 34. The foaming box 31 is also provided with a water-gas-liquid inlet 35 communicating with the liquid mixing chamber 33 and a bubble outlet 36 communicating with the bubble discharging chamber 34. The water-gas-liquid inlet 35 is connected to the liquid pumping assembly 7 and the foaming outlet 45. When the foaming assembly 3 works, the foaming liquid in the liquid storage box 5 is pumped by the liquid pumping assembly 7 and enters the liquid mixing chamber 33 through the water-gas-liquid inlet 35. At the same time, the water-gas mixture output from the foaming outlet 45 enters the liquid mixing chamber 33 through the water-gas-liquid inlet 35. The water, air and foaming liquid entering the liquid mixing chamber 33 will collide and mix strongly in the liquid mixing chamber 33, and then pass through the microporous foaming member 32 to generate a large number of uniform bubbles and enter the bubble discharging chamber 34, and then are discharged through the bubble outlet 36. The foaming assembly 3 integrates the foaming function in a relatively small foaming inner cavity. Its structure is simple and compact, with low cost, easy to manufacture, assemble and maintain, and has good foaming effect. At the same time, this kind of foaming assembly 3 can fully mix and foam even when using foaming liquid with poor water compatibility (such as laundry detergent, hand sanitizer, dishwashing liquid, etc.), without the need for special foaming liquid, which is beneficial to cost saving and convenient for adding and supplementing.

[0033] The above-mentioned microcellular foaming component 32 is made of existing conventional materials. For example, ordinary sand, common plastics (such as ABS), resin, white corundum, silicon carbide, etc. can be used.

[0034] In this embodiment, the bubble discharge chamber 34 is located above the liquid mixing chamber 33, so that the mixture of water, air and foaming liquid moves from bottom to top, forms bubbles after passing through the microcellular foaming component 32, and then enters the bubble discharge chamber 34. And part of the mixture that fails to foam in time will drip down under the action of its own weight, pass through the microcellular foaming component 32 again for foaming and then be discharged. In this way, every drop of the mixture can be fully converted into a large number of tiny bubbles, greatly reducing the usage amount of the foaming liquid without affecting the foaming effect.

[0035] In this embodiment, the microcellular foaming component 32 has a recessed portion 321, and the recessed portion 321 and the cavity wall of the foaming inner cavity enclose the liquid mixing chamber 33. Without increasing the size of the foaming inner cavity and the microcellular foaming component 32, this kind of liquid mixing chamber 33 enables the mixture in the liquid mixing chamber 33 to have a larger contact area with the microcellular foaming component 32, and the path of part of the mixture passing through the microcellular foaming component 32 is longer, which can further improve the foaming effect.

[0036] In this embodiment, the foaming box 31 includes a box body 311 and a sealing cover 312. The box body 311 has a cavity with one end open, and the sealing cover 312 is detachably connected to the box body 311 through fasteners and closes the opening of the cavity to form a foaming inner cavity. By disassembling the sealing cover 312, it is convenient to maintain and replace the microcellular foaming component 32. The above-mentioned sealing cover 312 is connected to the box body 311 through a plurality of screws, and at the same time, a sealing ring is provided between the sealing cover 312 and the box body 311 to improve the sealing performance.

[0037] In this embodiment, the sealing cover 312 has more than one pressing rod portion 3121, and the microcellular foaming component 32 is pressed between the cavity wall of the foaming inner cavity and more than one pressing rod portion 3121, so that the microcellular foaming component 32 is fixed in the foaming inner cavity. This kind of installation structure and method does not require a positioning structure for positioning the microcellular foaming component 32 in the foaming inner cavity, which can simplify the structure, reduce the manufacturing difficulty and cost, and the disassembly and assembly of the microcellular foaming component 32 are more convenient.

[0038] In this embodiment, the liquid pumping assembly 7 includes a liquid pump 71. The inlet of the liquid pump 71 is connected to the liquid storage box 5 through a liquid inlet pipe 72, and the outlet of the liquid pump 71 is connected to the water-gas-liquid inlet 35 through a liquid outlet pipe 73. When the liquid pump 71 works, it can pump the foaming liquid in the liquid storage box 5 to the liquid mixing chamber 33.

[0039] In this embodiment, the foam box 31 further has a pump housing cavity, and the liquid extraction pump 71 is installed in the pump housing cavity, which is beneficial to improving the installation convenience and structural compactness. Moreover, a shock-absorbing component 8 is provided between the liquid extraction pump 71 and the inner wall of the pump housing cavity, so as to avoid strong resonance and noise generated between the liquid extraction pump 71 and the outer shell of the foam box 31 during operation.

[0040] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art of this technology, the improvements and transformations obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
