Description

Technical Field

[0001] The invention relates to the technical field of foam suppliers, and in particular to a foam generating device capable of stably outputting foam water and a bathroom device. Background Art

[0002] The existing foam supply device has a short mixing path for gas-liquid mixing and a simple structure, resulting in insufficient contact area between gas and liquid. Such devices are difficult to form uniform turbulence during the mixing process, resulting in uneven distribution of the mixed medium, and the generated foam has problems such as large differences in bubble particle size and poor stability. Especially under high flow conditions, the phenomenon of insufficient mixing is aggravated, affecting the fineness of the foam and the user experience.

[0003] In the prior art, the back pressure problem of the foam generating device is also prominent. When the internal resistance of the mixing chamber increases, the water flow rate decreases significantly, and even the bubble water cannot flow out. Some devices increase the output pressure by adding power elements, but the resulting increase in energy consumption and structural complexity limit the actual application scenarios of the product.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] Embodiment 1: Figure 1 To Figure Fig.11 As shown, an embodiment of the present invention provides a foam generating device for stably outputting foam water, which comprises 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.

[0046] 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 provided with a foaming cavity 23, and a plurality of foaming nets 18 and a plurality of foaming pads 19 arranged at intervals 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 through pipelines. The foaming component 12, the liquid inlet component 11, the air inlet component 13 and the water inlet component 10 are arranged separately or integrally. The liquid inlet component 11 and the water inlet component 10 are constructed to be able to mix the washing liquid and clean water and input them together into the foaming cavity 23. Preferably, the thickness of the foaming pad 19 is greater than that of the foaming net 18. Figures 9 to 11 As shown, the foaming pad 19 is constructed as a ring structure. In an optional embodiment, as Fig.11 As shown, the inner diameters of the plurality of foaming pads 19 are arranged at intervals of one large and one small. In this embodiment, the inner diameters of the foaming pads 19 are the same.

[0047] Specifically, the flow path length of the gas-liquid mixed medium is effectively increased by adopting the alternating arrangement structure of the multi-layer bubbling net 18 and the bubbling pad 19. When the mixed liquid flows through the annular pads with different inner diameters, multiple flow velocity change zones are formed in the cavity, for example, a slow flow zone is formed at the pad position with a larger diameter, and a turbulent flow zone is formed at the position with a smaller diameter. This alternating flow causes a violent shearing effect on the gas and liquid.

[0048] Based on the above embodiments, in an optional embodiment of the present invention, as Figure 5 and Figure 7 As shown (where Figure 5 The structure under the split structure is shown. Figure 7, the structure under the integrated structure is shown), the air inlet component 13 is provided with an air inlet channel 20. The air inlet channel 20 is suitable for connecting to the bubbling cavity 23. The water inlet component 10 is provided with a water inlet channel 15 and a liquid mixing channel 14 connected to the water inlet channel 15. The liquid mixing channel 14 is suitable for connecting to the bubbling cavity 23. The liquid inlet component is provided with a liquid inlet channel 16. At least part of the liquid inlet channel 16 is configured to extend from the side wall of the liquid mixing channel 14 into the liquid mixing channel 14, so that the cross section of the liquid mixing channel 14 at the end position of the liquid inlet channel 16 becomes smaller. The axial direction of the liquid inlet channel 16 is perpendicular to the axial direction of the liquid mixing channel 14. Preferably, the end of the liquid inlet channel 16 is inclined, and the lower side of the end is arranged in the liquid mixing channel 14 facing the bubbling cavity 23, so that the cross section of the liquid inlet channel 16 at the end position of the liquid inlet channel 16 first becomes smaller and then becomes larger.

[0049] 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 point, sucking the washing liquid into a vortex mixing. Preferably, the end inclination angle of the liquid inlet channel 16 is set to 15° to further improve the mixing efficiency of clean water and washing liquid.

[0050] More preferably, the air inlet channel 20 and the liquid mixing channel 14 are respectively arranged on both sides of the bubble chamber 23, facing each other, and set with angles in opposite directions, so that the mixed solution and gas can form a spiral gas-liquid mixing flow after entering the bubble chamber 23, so as to further improve the mixing effect.

[0051] Based on the above embodiments, in an optional embodiment of the present invention, as Figures 2 to 6 As shown, the liquid inlet component 11 is provided with a plurality of the liquid mixing channels 14 at intervals. The liquid inlet channel 16 is provided with a plurality of the liquid inlet channels 16 correspondingly. The plurality of the foaming pads 19 are provided with avoidance grooves at the positions where the liquid mixing channels 14 are connected to the foaming chamber 23, so as to allow the mixed solution to enter the foaming chamber 23 from the liquid mixing channels 14. In an optional embodiment, as Figure 7 As shown, the bubbling assembly 12 , the liquid inlet member 11 , the air inlet member 13 and the water inlet member 10 are integrally arranged. The liquid mixing channel 14 and the air inlet channel 20 are connected to the end of the bubbling cavity 23 .

[0052] Specifically, when a split structure is adopted, each functional module can be optimized independently to adapt to detergents of different concentrations, and the modules can be replaced and adjusted according to different requirements of foam water, thereby significantly improving product adaptability.

[0053] The water outlet mechanism is connected to the foaming mechanism 9 to output the mixed foam water. Preferably, the water outlet mechanism includes a water outlet member 4. The water outlet mechanism also includes an impeller pump 5 connected between the foaming mechanism 9 and the water outlet member 4. Specifically, the impeller pump 5 can further reduce the back pressure, effectively solving the problem of insufficient output pressure of the traditional foam generating device.

[0054] The water supply mechanism is connected to the water inlet component 10 to deliver 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 be connected 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 pipeline is connected to the water inlet component 10. The second water outlet channel pipeline is connected to the bubble 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 bubble chamber 23.

[0055] Specifically, the dual-channel water supply system can realize continuous switching between foam water and ordinary clean water. In conjunction with the use of a pressure reducing valve, the quality of foam generation is ensured while preventing high-pressure water from directly impacting the foaming net 18 and causing structural damage.

[0056] The liquid supply mechanism is connected to the liquid inlet member to deliver washing liquid to the liquid inlet member 11. Preferably, the liquid supply mechanism includes a peristaltic pump 7 whose pipeline is connected to the liquid inlet member 11, and a liquid storage box 8 whose pipeline is connected to the peristaltic pump 7. The liquid storage box 8 is suitable for containing washing liquid. In other embodiments, the liquid storage box 8 may not be provided and may be directly extended into the existing packaging box through a pipeline. The peristaltic pump 7 can further ensure the supply of washing liquid, avoiding the problem that the suction force generated by the Venturi effect is insufficient and the washing liquid cannot be sucked.

[0057] The air supply mechanism is connected to the air intake member to deliver gas to the air intake member. Preferably, the air supply mechanism comprises an air pump 6 connected to the air intake member 13 through a pipeline.

[0058] 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 to control the operation or stop of the 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 to control the start and stop.

[0059] The foam generating device of the present invention can effectively avoid the problem that the bubble water cannot flow out due to too strong back pressure by combining the foaming component 12, the liquid inlet component 11, the air inlet component 13 and the water inlet component 10. It can also more fully mix the clean water, the gas and the washing liquid, thereby outputting fine foam with uniform particle size and high stability.

[0060] On the basis of the above embodiment, in an optional embodiment of the present invention, the shell member includes an upper shell 21 and a lower shell 22; the bubble chamber 23 is provided between the upper shell 21 and the lower shell 22; the upper shell 21 is suitable for being joined to the liquid inlet member 11, the air inlet member 13 and the water inlet member 10; the lower shell 22 is suitable for being joined to the water outlet mechanism. Preferably, the lower shell 22 is detachably and sealingly joined to the upper shell 21.

[0061] Embodiment 2: The present application further provides a bathroom device, which includes a foam generating device for stably outputting foam water as described in any paragraph of Embodiment 1, and a shower head and / or faucet connected to the foam generating device.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
