Description

Technical Field

[0001] This utility model relates to the technical field of foam supply devices, and more specifically, to a foam supply device and a bathroom device with foam supply function. Background Technology

[0002] Existing foam supply devices generally employ a technology that mixes detergent, gas, and water to generate foam. However, in practical applications, it has been found that traditional devices suffer from serious technical defects when the detergent concentration is high or contains thickening agents: the flow resistance of the viscous liquid in the delivery pipeline increases significantly, especially in low-temperature environments, where some detergents may even become semi-solid, causing complete blockage of the supply pipeline. These problems directly lead to the foamer being unable to obtain a stable supply of detergent, resulting in a precipitous drop in foam generation efficiency, and in severe cases, the entire system may completely lose its function.

Detailed Implementation

[0036] 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.

[0037] Example 1, by Figures 1 to 9 As shown, this utility model embodiment provides a foam feeder, which includes a foamer 6, an air supply mechanism, a liquid supply mechanism, a water inlet mechanism, a water outlet mechanism, and a control mechanism 14.

[0038] A foamer 6 is adapted to mix input detergent liquid, gas, and water into foam. A gas supply mechanism is coupled to the foamer 6 to supply gas to the foamer 6. A liquid supply mechanism is coupled to the foamer 6 to supply detergent liquid to the foamer 6. The liquid supply mechanism includes a liquid reservoir 5 for holding detergent and a stirring assembly coupled to the liquid reservoir 5. The stirring assembly is configured to agitate the liquid within the liquid reservoir 5. A water inlet mechanism is coupled to the foamer 6 and the liquid reservoir 5. The water inlet mechanism is configured to supply water to both the foamer 6 and the liquid reservoir 5. A water outlet mechanism is coupled to the foamer 6 and adapted to output the foam mixed by the foamer 6. A control mechanism 14 is electrically connected to the gas supply mechanism, the liquid supply mechanism, and the water inlet mechanism.

[0039] This foam feeder dilutes the washing liquid by injecting water into the storage tank 5 through the water inlet mechanism. Combined with the dynamic mixing of the stirring component, it significantly reduces the viscosity of the washing liquid. Especially in low-temperature environments, it prevents viscous liquid from solidifying and clogging the pipeline. It ensures a dynamic balance between washing liquid flowability, gas supply stability, and water pressure, thereby solving the problem of liquid supply interruption caused by liquid viscosity in traditional devices. The overall architecture optimization of this device improves the reliability and stability of system operation.

[0040] Preferably, the liquid supply mechanism includes a peristaltic pump 9 connected between the liquid storage box 5 and the aerator 6. The air supply mechanism includes an air pump 11 connected to the aerator 6. The water outlet mechanism further includes an impeller pump 10. The impeller pump 10 is connected between the output end of the aerator 6 and the water outlet connector 13.

[0041] Specifically, the peristaltic pump 9 delivers the washing liquid through flexible extrusion, avoiding the adhesion of viscous liquid to the internal structure of the pump body, while achieving precise flow control; the air pump 11 and the impeller pump 10 work together, with the former ensuring that the gas is evenly mixed into the liquid, and the latter increasing the foam output power through centrifugal pressurization, so that high-viscosity foam can still overcome pipeline resistance and be stably discharged.

[0042] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the stirring assembly includes a first motor 4 located below the liquid storage box 5, a magnet mounting base 3 connected to the output end of the motor, a drive magnet 2 connected to the magnet mounting base, and a stirring magnet 1 placed inside the liquid storage box 5. The stirring magnet 1 is constructed as an elongated structure with one direction longer than the others. The motor is adapted to drive the drive magnet 2 to rotate, thereby enabling the stirring magnet 1 to rotate and stir the washing liquid in the liquid storage box 5. In other embodiments, the stirring assembly may further include an ultrasonic transducer and / or a blade stirring component connected to the liquid storage box 5.

[0043] Specifically, the magnetic coupling drive design completely eliminates the risk of leakage at the seal of the liquid storage box 5, making it particularly suitable for humid bathroom environments; the long strip stirring magnet 1 increases the contact area with the liquid, creating a turbulence effect and improving the mixing efficiency of high-viscosity liquids; the ultrasonic transducer can further disperse colloidal particles in the washing liquid through cavitation, preventing stratification or sedimentation.

[0044] Based on the above embodiments, in an optional embodiment of the present invention, such as... Figure 1 , Figure 6 and Figure 7As shown, the water inlet mechanism includes an inlet connector 12 and a switching valve 8. The water outlet mechanism includes an outlet connector 13. The output end of the aerator 6, the inlet connector 12, and the outlet connector 13 are all connected to the switching valve 8 via pipelines. The switching valve 8 is configured to switch the inlet connector 12 to either the aerator 6 or the outlet connector 13. The outlet connector 13 is connected to the output end of the aerator 6 via the switching valve 8, or directly to the output end of the aerator 6 via a pipeline. Preferably, the water inlet mechanism further includes a pressure reducing valve 7. The pressure reducing valve 7 is engaged between the inlet connector 12 and the switching valve 8, or between the switching valve 8 and the aerator 6.

[0045] Specifically, in this embodiment, the foam feeder can seamlessly switch between three operating modes via the switching valve 8: Mode 1, regular water flow mode (water flows directly to the outlet); Mode 2, foam generation mode (water, air, and detergent are mixed); Mode 3, water replenishment mode for the storage box 5. The pressure reducing valve 7 dynamically adjusts the water pressure to the optimal foaming pressure range of 0.1-0.3 MPa during foam generation to prevent high-pressure water from damaging the foam structure; in water replenishment mode, it increases the water pressure to above 0.5 MPa to accelerate the dilution and stirring process of the liquid in the storage box 5.

[0046] Figure 2 The water path of the foam feeder during natural water flow is shown. When the water path adopts... Figure 6 In this layout, the water flows sequentially through the inlet connector 12, the switching valve 8, and the outlet connector 13. When the water circuit adopts... Figure 7 When the layout is in place, the water flows sequentially through the inlet connector 12, the pressure reducing valve 7, the switching valve 8, and the outlet connector 13.

[0047] Figure 3 The diagram illustrates the water path of the foam feeder during foam supply. The washing liquid flows sequentially through the reservoir 5, the supply mechanism, and the aerator 6. When the water path adopts... Figure 6 In this layout, the water flows sequentially through the inlet connector 12, the switching valve 8, the pressure reducing valve 7, and the aerator 6. When the water circuit adopts... Figure 7 In this layout, water flows sequentially through the pressure reducing valve 7, the water inlet connector 12, the switching valve 8, and the aerator 6. Gas flows once through the gas supply mechanism and the aerator 6. The washing liquid, clean water, and gas mix in the aerator 6 to form bubble water. When the water circuit adopts... Figure 6 In this layout, bubble water flows out from the outlet connection 13 via impeller pump 10 and switching valve 8. When the water circuit adopts... Figure 7 In this configuration, bubble water flows directly from the outlet connector 13 via the impeller pump 10.

[0048] Figure 4The diagram shows the water path when the foam feeder supplies water to the storage tank 5. The switching valve 8 is directly connected to the inlet connector 12 and the storage tank 5, supplying water to the storage tank 5.

[0049] Specifically, Figure 6 The pipeline connection scheme shown adopts a dual water path layout. Figure 6 By optimizing the valve body position, the pressure reducing valve 7 can play different roles in two modes: it does not reduce water pressure during normal water output, and reduces water pressure during foam output to precisely control the pressure required for foaming.

[0050] Based on the above embodiments, in an optional embodiment of the present invention, the bubbler 6 includes a housing assembly 17 having a foaming chamber and a foaming component disposed in the foaming chamber. The foaming component includes a plurality of foaming filters 16 and pads 15 spaced apart in the foaming chamber. The thickness of the pads 15 is greater than the thickness of the foaming filters 16. Preferably, the foaming filters 16 are provided with a plurality of foaming holes.

[0051] Specifically, the filter employs 5 to 10 layers of gradient-distributed foaming screens 16, subjecting the mixed liquid to multiple shearing and pressure surges, resulting in a fineness improvement of over 40%. The thick pads 15 also buffer water flow impacts, extending the filter's lifespan.

[0052] Example 2: This application also provides a bathroom device with a foam supply function, which includes a foam supply device as described in any paragraph of Example 1, and a shower head and / or spray nozzle and / or faucet connected to the water outlet mechanism of the foam supply device.

[0053] By integrating a foam dispenser with common bathroom fixtures, users can flexibly choose between using foam or regular water for daily cleaning, depending on their needs. Foam cleaning removes stains more effectively, reduces detergent usage, and is gentler on skin and surfaces, suitable for various scenarios such as handwashing, face washing, and showering. Regular water rinsing allows for quick rinsing or removing residual foam, meeting diverse cleaning requirements and providing a more convenient, efficient, and environmentally friendly cleaning experience.

[0054] 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.
