Description

Technical Field

[0001] This utility model relates to the field of foam supply technology, specifically to a foam water generating device and a bathroom device. Background Technology

[0002] Existing foam supply devices typically use a single mixing chamber for gas-liquid mixing. This results in a short mixing path and a simple structure, leading to insufficient contact area between the gas and liquid. Such devices struggle to generate uniform turbulence during mixing, resulting in uneven distribution of the mixing medium and foam exhibiting large differences in bubble size and poor stability. This incomplete mixing is exacerbated, especially under high flow rates, affecting foam fineness and user experience. Utility Model Content

Detailed Implementation

[0043] 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.

[0044] Example 1, by Figure 1 To the diagram Figure 11 As shown in the figure, this utility model embodiment provides a foam water generating device, which includes a foaming mechanism 9, a liquid supply mechanism, an air supply mechanism, a water supply mechanism, a water outlet mechanism, and a control mechanism 1.

[0045] The foaming mechanism 9 includes a foaming component 12, a liquid inlet component 11, an air inlet component 13, and a water inlet component 10. The foaming component 12 includes a shell component 17 with a foaming cavity 23, and multiple foaming nets 18 and multiple foaming pads 19 spaced apart from each other in the foaming cavity 23. The water inlet component 10, the liquid inlet component, and the air inlet component are all connected to the foaming cavity 23 via pipelines. The foaming component 12, the liquid inlet component 11, the air inlet component 13, and the water inlet component 10 are either separately or integrally arranged. The liquid inlet component 11 and the water inlet component 10 are configured to mix detergent and water and then input them together into the foaming cavity 23. Preferably, the thickness of the foaming pads 19 is greater than that of the foaming nets 18. Figures 9 to 11 As shown, the foam pad 19 is constructed in a ring shape. In an optional embodiment, as... Figure 11 As shown, the inner diameters of the multiple foam pads 19 are spaced apart, with one being larger and the other smaller. In this embodiment, the inner diameters of the foam pads 19 are the same.

[0046] Specifically, by employing an alternating arrangement of multi-layered foaming mesh 18 and foaming pads 19, the flow path length of the gas-liquid mixture is effectively increased. When the mixture flows through annular pads of different inner diameters, multiple velocity variation zones are formed within the cavity. For example, a slow-flow zone is formed at the location of the larger diameter pad, while a turbulent zone is formed at the location of the smaller diameter pad. This alternating flow causes the gas and liquid to undergo intense shearing action.

[0047] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figure 5 and Figure 7 As shown (where, Figure 5 The structure under the split structure is shown. Figure 7 (Structure shown in an integrated configuration) The air intake component 13 is provided with an air intake channel 20. The air intake channel 20 is adapted to communicate with the foaming cavity 23. The water intake component 10 is provided with a water intake channel 15 and a mixing channel 14. The mixing channel 14 is adapted to communicate with the foaming cavity 23. The liquid intake component is provided with a liquid intake channel 16. The liquid intake channel 16 extends from the side wall of the mixing channel 14 into the mixing channel 14, such that the cross-section of the mixing channel 14 decreases at its end position. The axial direction of the liquid intake channel 16 is perpendicular to the axial direction of the mixing channel 14. Preferably, the end of the liquid intake channel 16 is inclined, and the lower end faces the foaming cavity 23 within the mixing channel 14, so that the cross-section of the liquid intake channel 16 first decreases and then increases at its end position.

[0048] Specifically, the inclined end of the liquid inlet channel 16 is designed to form a Venturi effect acceleration zone. When clean water enters, a local negative pressure is formed at the channel diameter change, drawing in the washing liquid and generating a vortex mixing. Preferably, the inclination angle of the end of the liquid inlet channel 16 is set to 15° to further improve the mixing efficiency of clean water and washing liquid.

[0049] More preferably, the air inlet channel 20 and the liquid mixing channel 14 are respectively located on both sides of the foaming cavity 23, facing each other, and are provided with an angle in opposite directions, so that the mixed solution and gas can form a spiral gas-liquid mixed flow after entering the foaming cavity 23, so as to further improve the mixing effect.

[0050] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figures 2 to 6 As shown, the liquid inlet component 11 is provided with a plurality of mixing channels 14 at intervals. Correspondingly, a plurality of liquid inlet channels 16 are provided. A plurality of foaming pads 19 are respectively provided with clearance grooves at the positions where the mixing channels 14 connect to the foaming chamber 23, so that the mixed solution can enter the foaming chamber 23 from the mixing channels 14. In an optional embodiment, as... Figure 7 As shown, the foaming component 12, the liquid inlet component 11, the air inlet component 13, and the water inlet component 10 are integrally formed. The mixing channel 14 and the air inlet channel 20 are connected to the ends of the foaming cavity 23.

[0051] Specifically, when a split structure is adopted, each functional module can be optimized independently to adapt to different concentrations of detergent and to replace and adjust modules according to different requirements of foam water, thus significantly improving product adaptability.

[0052] A water outlet mechanism is connected to the foaming mechanism 9 to output the mixed foamed water. Preferably, the water outlet mechanism includes a water outlet component 4. The water outlet mechanism also includes an impeller pump 5 connected between the foaming mechanism 9 and the water outlet component 4. Specifically, the impeller pump 5 can further reduce back pressure, effectively solving the problem of insufficient output pressure in traditional foam generating devices.

[0053] A water supply mechanism is connected to the water inlet component 10 to supply clean water to the water inlet component 10. Preferably, the water supply mechanism includes a switching valve 2, a water inlet component 3, and a pressure reducing valve. The switching valve 2 is configured to connect to an external water source through the water inlet component 3. The switching valve 2 is provided with a first water outlet channel and a second water outlet channel. The first water outlet channel is connected to the water inlet component 10. The second water outlet channel is connected to the aerating chamber 23 or the water outlet component 4. The pressure reducing valve is connected between the water inlet component 3 and the switching valve 2, or between the first water outlet channel and the aerating chamber 23.

[0054] Specifically, the dual-channel water supply system allows for seamless switching between foamy water and regular clean water. Combined with a pressure-reducing valve, this ensures the quality of foam generation while preventing high-pressure water from directly impacting the foaming net 18 and causing structural damage.

[0055] A liquid supply mechanism is engaged with the liquid inlet component 11 to deliver washing liquid to the liquid inlet component 11. Preferably, the liquid supply mechanism includes a peristaltic pump 7 connected to the liquid inlet component 11 via a conduit, and a liquid reservoir 8 connected to the peristaltic pump 7 via a conduit. The liquid reservoir 8 is adapted to hold the washing liquid. In other embodiments, the liquid reservoir 8 may be omitted, and the liquid may be directly inserted into the existing packaging box via a conduit. The peristaltic pump 7 further ensures the supply of washing liquid and avoids the problem of insufficient suction due to the Venturi effect, which prevents the washing liquid from being drawn up.

[0056] An air supply mechanism is coupled to the air intake component for supplying gas to the air intake component. Preferably, the air supply mechanism includes an air pump 6 connected in conduit to the air intake component 13.

[0057] The control mechanism 1 is electrically connected to the liquid supply mechanism, the air supply mechanism, the water supply mechanism, and the water outlet mechanism, and is used to control the operation or stop of the control mechanism 1. Preferably, the control mechanism 1 includes a control circuit board and a battery. The circuit board is electrically connected to the battery, the impeller pump 5, the switching valve 2, the air pump 6, and the peristaltic pump 7, and is used to control the start and stop.

[0058] The foam water generating device of this invention combines a foaming component 12, a liquid inlet component 11, an air inlet component 13, and a water inlet component 10. This not only effectively avoids the problem of foam water not being able to flow out due to excessive back pressure, but also allows for more thorough mixing of clean water, gas, and detergent, thereby outputting fine foam with uniform particle size and high stability.

[0059] Example 2: This application also provides a bathroom device, which includes a foam water generating device as described in any paragraph of Example 1, and a shower head and / or faucet connected to the foam water generating device.

[0060] 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.
