Description

Technical Field

[0001] This utility model relates to the field of foaming device technology, specifically to a liquid mixing foaming device and a bathing device capable of outputting foam. Background Technology

[0002] Existing foam-generating devices (such as bubble machines or spa bath equipment) have significant shortcomings in foam production. For example, during the foaming process, the mixing of liquid and gas is insufficient, resulting in insufficient foam production and poor foam fineness and stability. This not only affects the user experience, but also, traditional foaming devices have structural design flaws, such as inefficient liquid and gas delivery paths, leading to low mixing efficiency and consequently affecting the quality of foam generation.

[0003] On the other hand, the structural design within the foaming chamber fails to adequately consider the hybrid dynamics of liquid and gas, resulting in significant energy loss during the mixing process and further reducing foam generation efficiency. These issues, to some extent, limit the applicability and performance of the foaming device in various application scenarios. Utility Model Content

Detailed Implementation

[0030] 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 a part of the embodiments of this utility model, not all of them. 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 represents selected 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.

[0031] Example 1, by Figures 1 to 7 As shown, this utility model embodiment provides a liquid-to-foam device, including a foamer 6, a liquid pump 8 and a gas pump 10 connected to the foamer 6 via pipelines, a water outlet connector 12 and a switching valve 2, and a water inlet connector 1 connected to the switching valve 2 via pipelines. The foamer 6 includes a housing assembly with a foaming chamber 24 and a foaming component disposed in the foaming chamber 24. The housing assembly is provided with a first water inlet 20, a liquid inlet 22, an air inlet 18 and an outlet 25 communicating with the foaming chamber 24. The switching valve 2 is connected to the first water inlet 20 to input water into the first water inlet 20. The liquid pump 8 is connected to the liquid inlet 22 to input washing liquid into the liquid inlet 22. The gas pump 10 is connected to the air inlet 18 to input gas into the air inlet 18. The foaming component includes a plurality of foaming filters 15 and pads 16 spaced apart in the foaming chamber 24. The thickness of the pad 16 is greater than the thickness of the foaming filter 15.

[0032] This liquid-to-foam device optimizes the structural design of the foamer 6, significantly improving the mixing efficiency of liquid and gas. The spacing of multiple foaming filters 15 and pads 16 in the foaming assembly, and the design that the thickness of the pads 16 is greater than the thickness of the foaming filters 15, ensures that the liquid and gas are fully mixed in the foaming chamber 24, resulting in a significant increase in the amount of foam generated, and greatly improving its fineness and stability.

[0033] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figure 4The housing assembly includes an upper housing 13, a lower housing 17, and a sealing ring 14. The lower housing 17 is detachably engaged with the upper housing 13 to form the foaming chamber 24 between the upper housing 13 and the lower housing 17. The sealing ring 14 is engaged between the upper housing 13 and the lower housing 17. The upper housing 13 is provided with a first water inlet 20, a liquid inlet 22, and an air inlet 18. The lower housing 17 is provided with the outlet 25. Specifically, this detachable housing assembly design facilitates the assembly, maintenance, and cleaning of the foamer 6. The use of the sealing ring 14 ensures the sealing of the foaming chamber 24, preventing liquid and gas leakage and improving the safety and reliability of the device. This structural design not only extends the service life of the device but also reduces maintenance costs.

[0034] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figure 7 As shown, the housing assembly further includes a second water inlet 23, a water passage 19 connecting the first water inlet 20 and the outlet 25, and a mixing channel connecting the second water inlet 23 and the water passage 19. The liquid inlet 22 is connected to the mixing channel. At least a portion of the diameter of the mixing channel is smaller than that of the water passage 19.

[0035] The housing assembly is designed with several key components, including a first inlet 20, a second inlet 23, an outlet 25, a water passage 19, and a mixing passage, which together form a complex fluid system. The purpose of this design is to achieve precise liquid mixing and control.

[0036] The water passage 19 connects the first inlet 20 and the outlet 25, forming the main fluid path for use when outputting clean water. The liquid inlet 22 is connected to the mixing channel, which in turn connects the second inlet 23 and the water passage 19. This allows the washing liquid and clean water to mix in the mixing channel before being transported to the water passage 19 to mix with gas and create foam, thus optimizing the mixing effect.

[0037] Preferably, the liquid inlet 22 extends into the mixing channel at a diameter smaller than that of the water passage 19, and the depth of insertion is three-quarters of the diameter of the mixing channel, so that when clean water is introduced into the second water inlet 23, a negative pressure can be formed at one end of the liquid inlet 22 connected to the mixing channel, thereby fully mixing the washing liquid and clean water.

[0038] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figures 5 to 7As shown, the first water inlet 20, the mixing channel, and the air inlet 18 are located on the same side of the foaming assembly. The outlet 25 is located on the side of the foaming assembly away from the mixing channel. This layout design makes the flow of fluid in the foaming chamber 24 more rational and improves the mixing effect.

[0039] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figure 6 As shown, the pad 16 is constructed in a ring shape. Multiple pads 16 are spaced apart with varying inner diameters. Preferably, the pad 16 with the smaller inner diameter has a first air passage for connecting to the bubble chamber 24. The housing assembly also has a second air passage for connecting the air inlet 18 and the first air passage. In other embodiments, the inner diameters of the multiple pads 16 can be set to the same size; this invention does not specifically limit this.

[0040] The pad 16 is constructed in a ring shape. This design allows the pad 16 to be evenly distributed and fixed within the foaming chamber 24, ensuring stable flow of gas and liquid during the foaming process. The ring-shaped pad 16 not only facilitates installation but also effectively reduces resistance to gas and liquid flow, thereby improving foaming efficiency.

[0041] The multiple spacers 16, with varying inner diameters, optimize the flow path of gas and liquid, preventing dead zones from forming within the bubble chamber 24. This allows the gas and liquid to form vortices as they pass through, further enhancing the bubble formation effect. This design also reduces bubble coalescence, improving bubble uniformity and stability.

[0042] The smaller inner diameter pad 16 is provided with a first air passage for connecting the foaming chamber 24. The housing assembly is also provided with a second air passage for connecting the air inlet 18 and the first air passage. The design of the second air passage enables efficient delivery of gas from the air inlet 18 to the first air passage, reducing gas leakage and loss during delivery, further improving the overall performance of the foaming device, and ensuring that the gas maintains a stable pressure and flow rate before entering the foaming chamber 24. The design of the first air passage enables direct introduction of gas into the core area of ​​the foaming chamber 24, ensuring full contact between the gas and the liquid. The first air passage also reduces energy loss of gas when entering the foaming chamber 24, improving gas utilization.

[0043] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figure 2As shown, the mixing foaming device further includes a liquid storage component 9, an impeller pump 11, a control component 4, a power supply component 3, a first one-way valve 7, and a second one-way valve 5. The liquid storage component 9 is connected to the liquid pump 8. The impeller pump 11 is connected to the output port 25 and the water outlet connector 12 to transport the material in the foaming chamber 24 to the water outlet connector 12. The control component 4 is electrically connected to the liquid pump 8, the gas pump 10, the switching valve 2, and the impeller pump 11. The power supply component 3 is electrically connected to the control component 4. The first one-way valve 7 is connected between the liquid pump 8 and the aerator 6. The second one-way valve 5 is connected between the gas pump 10 and the aerator 6.

[0044] The impeller pump 11 transports the foam or liquid in the foaming chamber 24 through the pipeline to the outlet connector 12, ensuring smooth foam output. The control component 4 is the core of the mixed-liquid foaming device, responsible for coordinating the operation of the liquid pump 8, gas pump 10, switching valve 2, and impeller pump 11. When the switching valve 2 is a mechanical valve, the control device can control the operation of the liquid pump 8 and gas pump 10 based on the sensing signal from the switching valve 2. When the switching valve 2 is a solenoid valve, the control device can control the output water path of the switching valve 2, as well as the operation of the liquid pump 8 and gas pump 10, based on the control signal.

[0045] The liquid reservoir 9 is connected to the liquid pump 8 via piping. The liquid pump 8 draws the washing liquid from the liquid reservoir 9 and delivers it to the aerator 6. A first check valve 7 and a second check valve 5 are respectively installed on the piping between the liquid pump 8 and the gas pump 10 and the aerator 6 to prevent liquid or gas backflow. The first check valve 7 ensures that the washing liquid can only flow from the liquid pump 8 to the aerator 6 and not in the opposite direction. The second check valve 5 ensures that gas can only flow from the gas pump 10 to the aerator 6, preventing gas leakage or backflow.

[0046] Example 2: This application also provides a bathing device capable of outputting foam, comprising the aforementioned liquid-mixing foam-output device, and a water outlet component connected to the output interface of the liquid-mixing foam-output device. Preferably, the water outlet component is a shower head.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
