[0002] Currently, in order to obtain stable and abundant soap foam directly in daily cleaning or hygiene situations, especially in kitchen and bathroom settings, the usual method is to premix water, air and soap in a certain proportion, and then generate foam through a foam generator for users.

[0003] Traditional liquid dispensing devices typically output soap solution to the water outlet terminal for gas-liquid mixing. This makes it difficult to unify and centrally arrange the water and gas sources. Furthermore, the various pumps, mixers, and liquid inlet channels are relatively dispersed, resulting in a large overall size and complex installation, which is not conducive to miniaturization or embedded applications. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a mixing liquid dispensing device and a water dispensing faucet to solve the above problems.

[0005] The present invention adopts the following solution:

The foamer is used to fully mix water, air, and soap solution in the mixing chamber. The liquid outlet connector is connected to the external foamer.

[0007] As a further improvement, the main body of the waterway and the pump assembly are independent of each other and are arranged adjacent to each other front and back.

[0008] As a further improvement, the peristaltic pump is connected to an external soap container via one pipe and to an inlet connector via another pipe.

[0009] As a further improvement, an adjustment knob is provided on the main body of the water channel, which can be operated to regulate the amount of soap solution input into the mixing chamber through the liquid inlet connector.

[0010] As a further improvement, at least two air pumps are provided side by side in the pump body assembly; wherein the two air pumps are respectively connected to the mixing chamber, or one air pump is connected to the mixing chamber and the other air pump is connected to the peristaltic pump.

[0011] As a further improvement, a control circuit board is also included; the waterway body is provided with a solenoid valve for switching on and off, and the solenoid valve, peristaltic pump and air pump are electrically connected to the control circuit board respectively.

[0012] As a further improvement, the outer shell of the machine body is composed of an upper shell and a lower shell, forming a box-shaped structure; the upper shell includes an upper cover plate and a front plate, the lower shell includes a lower bottom plate and a rear plate, and the upper shell and the lower shell respectively form side plates on both sides by assembly.

[0013] As a further improvement, the water inlet connector is correspondingly installed on one side plate, and the liquid inlet connector and liquid outlet connector are correspondingly installed on the bottom plate.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0029] Example

[0030] Combination Figures 1 to 8 This embodiment provides a mixing and dispensing device, including a housing 1, a water channel body 2, and a pump assembly 3. The water channel body 2 is equipped with a foamer 4, a water inlet connector 5, a liquid inlet connector 6, and a liquid outlet connector 7. The foamer 4 has a mixing chamber. The water inlet connector 5 and the liquid inlet connector 6 are respectively located at the liquid inlet end of the mixing chamber, and the liquid outlet connector 7 is located at the liquid outlet end of the mixing chamber. The pump assembly 3 includes at least a peristaltic pump 8 and an air pump 9. The peristaltic pump 8 is used to draw soap solution from the outside to the liquid inlet connector 6, and the air outlet end of the air pump 9 is connected to the mixing chamber. The foamer 4 is used to thoroughly mix water, air, and soap solution within the mixing chamber. The liquid outlet connector 7 is connected to an external foamer 10.

[0031] The aforementioned mixing and dispensing device is compactly arranged in the same outer casing 1 via a peristaltic pump 8 and an air pump 9, and is connected to the internal water channel body 2. This allows water, air, and soap solution to be uniformly input into the foamer 4 of the water channel body 2, where thorough gas-liquid mixing is completed. The foam bubbles output to the liquid outlet 7 and the foamer 10 are uniform and fine, meeting the needs of daily cleaning. The integrated arrangement of water inlet, air inlet, and liquid inlet within the water channel body 2 greatly improves the overall structural layout of the machine, facilitates maintenance, and makes the connection between air and liquid inlet more efficient and convenient.

[0032] In this embodiment, the waterway body 2 and the pump assembly 3 are independent of each other and arranged adjacent to each other front and back. On one hand, configuring the waterway body 2 and the pump assembly 3 as independent modular units, and arranging them adjacent to each other front and back within the housing 1, effectively isolates their vibrations and heat sources, preventing vibrations and heat from the pump from being directly transferred to the mixing chamber, thus improving overall stability and service life. On the other hand, during disassembly and maintenance, the pump assembly 3 or the waterway body 2 can be removed sequentially in stages, avoiding mutual interference, shortening maintenance time, and reducing maintenance difficulty. Simultaneously, the modular units are easy to assemble in parallel on the production assembly line, improving production efficiency.

[0033] In this embodiment, the peristaltic pump 8 is connected to an external soap container via one pipe and to an inlet connector 6 via another pipe. One end of the pipes at both ends of the peristaltic pump 8 is directly connected to the external soap container, and the other end is connected to the inlet connector 6, allowing the soap to be rapidly delivered within a fully enclosed flexible hose. Preferably, the soap in the soap container is dishwashing liquid, suitable for use with a kitchen faucet.

[0034] Obviously, the peristaltic pump 8 itself has good controllability. By controlling the pump speed, the amount of soap solution delivered per unit time can be accurately adjusted. The pipeline goes directly to the inlet connector 6, which reduces flow resistance and dead volume, and further improves the accuracy and response speed of quantitative delivery.

[0035] In this embodiment, a regulating knob 11 is provided on the main body 2 of the water channel. The regulating knob 11 can be operably adjusted to control the amount of soap solution input into the mixing chamber through the liquid inlet connector 6. It should be noted that the regulating knob 11 controls the flow rate of the soap solution by changing the liquid inlet opening, thereby achieving free switching from thin to thick foam concentration. For details, refer to the existing manual valve structure, so it will not be described in detail here.

[0036] In this embodiment, at least two air pumps 9 are arranged side-by-side within the pump body assembly 3. Each air pump 9 is connected to a mixing chamber, and the superimposed air source input increases the amount of gas in the mixing chamber, achieving a high concentration of gas-liquid mixing. Furthermore, the two independent air pumps 9 can continue to operate normally even if either air pump 9 fails.

[0037] In another embodiment, one air pump 9 is connected to the mixing chamber, and the other air pump 9 is connected to the peristaltic pump 8. One air pump 9 introduces air into the peristaltic pump 8, where it undergoes preliminary gas-liquid mixing with the soap solution, improving the flow properties of the soap solution and increasing the efficiency of soap solution delivery. Furthermore, it ensures that the already gas-liquid mixed soap solution can be further mixed more efficiently and thoroughly with water and air within the mixing chamber.

[0038] In this embodiment, a control circuit board 12 is also included. The water channel body 2 is equipped with a solenoid valve 13 for on / off switching. The solenoid valve 13, peristaltic pump 8, and air pump 9 are electrically connected to the control circuit board 12. Clearly, the external power connector of the control circuit board 12 supplies power to the entire device. As a central control module, the control circuit board 12 controls the operation of each pump and the opening and closing of the solenoid valve 13, thereby achieving automated control of the entire mixing and discharging device. Furthermore, the solenoid valve 13 is used to control the liquid inlet opening and closing of the peristaltic pump 8, or it can directly control the liquid outlet opening and closing of the foamer 4.

[0039] like Figure 2 and Figure 3 As shown, in this embodiment, the outer shell 1 is a box-shaped structure composed of an upper shell 14 and a lower shell 15. The upper shell 14 includes an upper cover plate and a front plate, and the lower shell 15 includes a lower bottom plate and a rear plate. The upper shell 14 and the lower shell 15 are respectively assembled on both sides to form side plates. Thus, the upper shell 14 and the lower shell 15 are each composed of two plates, and a complete side plate is formed by side assembly. The components are extremely simple, eliminating the need for additional side plates. During assembly, only the two shells need to be positioned opposite each other and assembled and connected on the sides, which greatly shortens the assembly time.

[0040] The water inlet connector 5 is located on one side panel, while the liquid inlet connector 6 and the liquid outlet connector 7 are located on the bottom panel. Positioning the water inlet connector 5 on the side panel allows for horizontal connection with pre-embedded indoor water supply pipes, eliminating the need for repeated bending or the use of long flexible hoses, thus reducing the difficulty of pipework construction. The concentration of the liquid inlet and outlet connectors 7 on the bottom panel facilitates downward arrangement of the soap container and foamer 10 piping, making installation more intuitive and faster.

[0041] Combination Figure 1 and Figure 6This embodiment also provides a faucet, including a faucet body 16 and an aerator 10 attached to the faucet body 16. The aerator 10 is connected to the above-mentioned mixing and dispensing device. Specifically, the aerator 10, as another dispensing component of the faucet body 16 independent of the faucet, can independently dispense foamed soap solution, greatly facilitating daily soap supply and cleaning.

[0042] The faucet body is equipped with a control switch 17 for controlling the opening and closing of the mixing and dispensing device. Preferably, the control switch 17 is a push-button switch, and the push-button switch circuit is connected to the control circuit board or wirelessly connected to the control circuit board, thereby controlling the liquid dispensing from the aerator by opening and closing the solenoid valve.

[0043] Furthermore, the aerator is connected to the front end of the faucet body via a ball joint 18. The ball joint 18 allows the aerator 10 to be more flexibly and angle-adjustable at the front end, greatly improving the overall usability of the kitchen and bathroom faucet and facilitating its widespread application.

[0044] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
