Description

[Technical Field]

[0001] This utility model relates to the field of foam machine technology, and in particular to a foam production device with active liquid supply. [Background Technology]

[0002] Foam machines mix liquid and gas in a gas-liquid mixing chamber, allowing detergent to be sprayed directly as foam without requiring users to manually rub the detergent repeatedly, thus providing a better user experience.

[0003] Existing foam machines typically use foaming nets to produce fine foam. However, for detergents with paste-like ingredients, such as facial cleansers, the foaming ability is extremely weak. Using foaming nets not only easily causes clogging but also results in poor foam production, failing to form dense foam. To address this, the inventors proposed a foam production solution using a gear pump. However, due to internal leakage, gear pumps cannot meet the extraction requirements for viscous detergents like facial cleansers, especially since air needs to be drawn in during foam production, and the gear pump preferentially draws in air with less resistance. Furthermore, for detergents like facial cleansers, shower gels, and shampoos, users are usually required to mix and dilute the detergent with water before use to ensure efficacy. Therefore, there is an urgent need for a foam production device that can actively supply liquid and prepare the mixture in real time. [Utility Model Content]

[0035] Please see Figures 1 to 6 As shown, this utility model discloses an active liquid supply foam production device 100, the foam production device 100 comprising:

[0036] 1. A housing, wherein a receiving space 11 is formed within the housing 1, the receiving space 11 being used to receive gears, liquids, gases, etc.;

[0037] An active foam-generating gear 2 and a driven foam-generating gear 3 are meshed and rotatably disposed within a receiving space 11. A suction chamber 111 is formed on the gear disengagement side of the receiving space 11, and a discharge chamber 112 is formed on the gear meshing side of the receiving space 11. The outer wall of the housing 1 is provided with a foam output port 12 communicating with the discharge chamber 112 and an air inlet 13 communicating with the suction chamber 111. The foam output port 12 is used to output foam to the outside when the output conditions are met, and the air inlet 13 is used to deliver outside air into the receiving space 11. The housing 1, the active foam-generating gear 2, and the driven foam-generating gear 3 together form a gear pump.

[0038] Active liquid supply device 4 is connected to the receiving space 11 and actively supplies the mixed liquid into the receiving space 11.

[0039] The drive device 5 is connected to the active foaming gear 2 at its output end, so that the drive device 5 can drive the meshing active foaming gear 2 and driven foaming gear 3 to rotate and realize foam production.

[0040] By adopting the above-mentioned technical solution of this utility model, at least the following beneficial effects are achieved: the foam production device 100 is designed to include an active liquid supply device 4, and the active liquid supply device 4 is connected to the accommodating space 11. During operation, the active liquid supply device 4 can be used to actively supply liquid to the gear pump that produces foam, thereby meeting the liquid supply requirements of the gear pump.

[0041] In this utility model, please refer to the following: Figures 4-6As shown, the active liquid supply device 4 includes a cup pump 41; the outlet of the cup pump 41 forms a liquid mixing chamber 411, and the outer wall of the cup pump 41 is provided with a water inlet 412 and a detergent inlet 413. The water inlet 412 is connected to the liquid mixing chamber 411 through a water inlet channel 414 to realize the input of clean water into the liquid mixing chamber 411. The detergent inlet 413 is connected to the liquid mixing chamber 411 through a detergent delivery channel 415 to realize the input of detergent into the liquid mixing chamber 411. The liquid mixing chamber 411 is connected to the receiving space 11 to realize the output of the mixed liquid into the receiving space 11. The liquid mixing chamber 411 is used for the passage of detergent and clean water and for mixing detergent and clean water. The water inlet 412 is used for the input of clean water, and the detergent inlet 413 is used for the input of detergent (such as facial cleanser). In a specific implementation of this invention, the detergent inlet 413 can be set at the top of the cup pump 41. Because detergents such as facial cleanser have high viscosity and are not easy to extract, by setting the detergent inlet 413 at the top of the cup pump 41, the detergent can be collected at the bottom of the container under the action of gravity, so as to better achieve the extraction of detergent.

[0042] Furthermore, the active liquid supply device 4 also includes a stirring assembly 42 disposed within the liquid mixing chamber 411, and the stirring assembly 42 is connected to the drive device 5. In a specific implementation of this invention, the drive device 5 is specifically a drive motor, and the active foaming gear 2, the cup pump 41, and the stirring assembly 42 use the same drive device 5 as a power source. Specifically, the active foaming gear 2, the cup pump 41, and the stirring assembly 42 can all be connected to the drive motor via a connecting shaft 51 and a gear set 52, so that one drive motor can drive the active foaming gear 2, the stirring assembly 42, and the cup pump 41 to work simultaneously. Meanwhile, the cup pump 41 and the gear pump can share a housing 1. By adopting the above structural design, on the one hand, the overall cost of the foam production device 100 can be effectively reduced, and on the other hand, the overall structure of the foam production device 100 can be made more compact, small, and aesthetically pleasing. Of course, the above is only a preferred embodiment of the present invention, but the present invention is not limited thereto. In specific implementation, independent drive devices 5 can be used for the active foaming gear 2, the stirring component 42 or the cup pump 41 according to actual needs, and corresponding housings can be provided for the cup pump 41 and the gear pump respectively.

[0043] This invention designs an active liquid supply device 4, which includes a cup pump 41 and a stirring assembly 42. A liquid mixing chamber 411 is formed at the outlet of the cup pump 41, and the stirring assembly 42 is placed inside the liquid mixing chamber 411. This allows the cup pump 41 to extract detergent and water in real time to prepare a mixture, thus ensuring the effectiveness of the detergent.

[0044] Furthermore, the liquid mixing chamber 411 includes an input region 4111, a mixing region 4112, and an output region 4113 connected in sequence, with the stirring assembly 42 located in the mixing region 4112; the water inlet channel 414 and the detergent delivery channel 415 are both connected to the input region 4111, and the accommodating space 11 is connected to the output region 4113. By adopting the above structural design, it can be ensured that the stirring assembly 42 can better stir, mix, and dilute the detergent and water to obtain a mixed liquid.

[0045] Furthermore, a one-way valve 43 is provided at the inlet of the input area 4111 and at the outlet of the corresponding output area 4113 in the receiving space 11 to prevent backflow of the mixture during operation. The one-way valve at the outlet of the corresponding output area 4113 in the receiving space 11 is not shown in the figure.

[0046] In this invention, the liquid mixing chamber 411 is connected to the suction chamber 111, which enables the liquid mixture delivered to the receiving space 11 to mix with the external air quickly to achieve foaming.

[0047] In this invention, the foam outlet 12 is located on the side wall of the housing 1 and is connected to the bottom of the discharge chamber 112 to ensure that the generated foam can be better output through the foam outlet 12 when the working pressure is established. Furthermore, in specific implementations, the diameter of the foam outlet 12 can be designed according to the actual foam output requirements.

[0048] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
