A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0038] In the description of this specification, reference to the terms "some embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.

[0039] In view of this, an embodiment of the present application provides a lotion dispensing device. Please refer to Figure 2. The lotion dispensing device includes a first lotion dispensing chamber 10a, a foam generating component, a lotion suction channel 30a and a gas suction channel 40a.

[0040] The first lotion delivery chamber 10a is used to contain lotion.

[0041] The type of detergent is not limited, for example, detergent, softener, etc. In the embodiment of the present application, the first detergent delivery chamber 10a is used as an example to describe the detergent.

[0042] In some embodiments, referring to Figures 1 and 2 , the detergent dispensing device further includes a cover 101. The top of the first detergent dispensing chamber 10a has a detergent dispensing port 101a. The cover 101 is used to open or close the detergent dispensing port 101a. Before washing clothes, the user can pre-dispense a certain amount of detergent into the first detergent dispensing chamber 10a through the detergent dispensing port 101a. The cover 101 prevents foreign matter from falling into the detergent dispensing port 101a.

[0043] In some embodiments, referring to FIG. 1 , the detergent dispensing device further includes a second detergent dispensing chamber 10 b , and the first detergent dispensing chamber 10 a and the second detergent dispensing chamber 10 b are not connected to each other and are arranged side by side.

[0044] The second lotion delivery chamber 10b is used to contain lotion.

[0045] For example, the top of the second detergent delivery chamber 10b is provided with a second detergent delivery port 101b, and the user can deliver detergent into the second detergent delivery chamber 10b through the second detergent delivery port 101b.

[0046] It should be noted that the type of detergent in the second detergent injection chamber 10b can be different from the type of detergent in the first detergent injection chamber 10a. For example, the first detergent injection chamber 10a contains detergent, and the second detergent injection chamber 10b contains disinfectant, softener, perfume, etc.

[0047] 1 and 2 , the foam generating assembly has an inlet 201 a and an outlet 201 b , and the inlet 201 a is used to connect to a water supply device.

[0048] The water supplied by the water supply device flows into the Venturi channel 20a through the inlet 201a and is discharged through the outlet 201b.

[0049] The water supply device is not limited and can be a water pipe or a water storage mechanism.

[0050] The detergent suction channel 30a is connected to the foam generating assembly and the first detergent delivery chamber 10a, and is used to guide the detergent in the first detergent delivery chamber 10a to the foam generating assembly under the action of negative pressure.

[0051] The gas suction channel 40a connects the foam generating component and the atmospheric environment, and is used to guide air to the foam generating component under the action of negative pressure.

[0052] Specifically, when the water supplied by the water supply device flows through the foam generating assembly, negative pressure is generated in the foam generating assembly, thereby sucking the detergent in the detergent suction channel 30a into the foam generating assembly, and the detergent in the first detergent delivery chamber 10a is continuously replenished into the detergent suction channel 30a, thereby continuously sucking the detergent in the first detergent delivery chamber 10a into the foam generating assembly, so that the detergent is mixed and dissolved in the water flow of the foam generating assembly. At the same time, due to the pressure difference, the outside air is sucked into the foam generating assembly from the gas suction channel 40a, and the gas, detergent, and water flow are mixed in the foam generating assembly. The air forms a large number of bubbles in the water flow, and the large number of bubbles promotes the dispersion and dissolution of the detergent. For the detergent, it can also promote the foaming of the detergent, so that the detergent and the water flow are better mixed and foamed, and dissolved more thoroughly, which can produce a better cleaning effect and also reduce the amount of detergent used.

[0053] The lotion dispensing device of the embodiment of the present application can be a hand-dispensing type, that is, there is no need to set up a dispensing pump to achieve sufficient mixing of lotion, water flow and air, thereby improving the foaming effect of the lotion and helping to reduce the cost of the lotion dispensing device.

[0054] In some embodiments, please refer to Figure 3, the foam generating component is a Venturi channel 20a, and the Venturi channel 20a includes a contraction section 200a, a throat section 200b and an expansion section 200c connected in sequence. The cross-sectional area of ​​the contraction section 200a and the cross-sectional area of ​​the expansion section 200c are both larger than the cross-sectional area of ​​the throat section 200b.

[0055] The Venturi channel 20a is a channel that can produce a Venturi effect, so as to generate negative pressure in the foam generating assembly.

[0056] The detergent suction channel 30a penetrates the inner surface of the throat section 200b. In other words, the detergent suction channel 30a is connected to the throat section 200b, and the internal spaces of the two are connected, so the detergent is more significantly adsorbed and can be more easily sucked into the venturi channel 20a.

[0057] In some embodiments, the air intake passage 40a extends through the inner surface of the throat section 200b. Similarly, since the air intake passage 40a is connected to the throat section 200b, the internal spaces of the two are interconnected, allowing external air to be more easily drawn into the Venturi passage 20a, thereby improving the reliability of the air intake of the detergent dispensing assembly.

[0058] The relative positional relationship between the foam generating assembly and the first lotion delivery chamber 10a is not limited. For example, the two can be arranged side by side in the horizontal direction, or arranged side by side in the vertical direction.

[0059] For example, referring to Figure 2 , the foam generating assembly is located below the first detergent dispensing chamber 10a, and the detergent intake passage 30a extends through the bottom surface of the first detergent dispensing chamber 10a. This allows the detergent to more easily enter the detergent intake passage 30a under its own weight, thus reducing the risk of emptying or clogging. Furthermore, the detergent in the first detergent dispensing chamber 10a is effectively drained, minimizing residual detergent in the chamber.

[0060] It should be noted that the relative positional relationship between the portion where the detergent suction channel 30a passes through the inner surface of the foam generating component and the portion where the gas suction channel 40a passes through the inner surface of the foam generating component is not limited.

[0061] For example, referring to Figures 2 and 3 , the portion where the gas intake channel 40a passes through the foam generating assembly and the portion where the detergent intake channel 30a passes through the foam generating assembly are arranged along the same straight line. In other words, the two portions are arranged toward each other. This allows the gas drawn into the foam generating assembly through the gas intake channel 40a and the detergent drawn into the foam generating assembly through the detergent intake channel 30a to impact each other, achieving a better mixed foaming effect.

[0062] In some embodiments, referring to Figures 2 and 3 , the minimum cross-sectional area of ​​the detergent intake channel 30a is smaller than the minimum cross-sectional area of ​​the air intake channel 40a. Consequently, the amount of air introduced into the air intake channel 40a per unit time is greater than the amount of detergent directed to the foam generating assembly by the detergent intake channel 30a. This increased air intake allows for more thorough dissolution of the detergent in the water flow, resulting in more complete foaming.

[0063] The minimum cross-sectional area of ​​the detergent intake passage 30a refers to the smallest cross-sectional area among all cross-sectional areas perpendicular to the detergent flow direction. The minimum cross-sectional area of ​​the gas intake passage 40a refers to the smallest cross-sectional area among all cross-sectional areas perpendicular to the gas flow direction.

[0064] The detergent suction channel 30a can be arranged with a constant cross section or a variable cross section. The gas suction channel 40a can be arranged with a constant cross section or a variable cross section.

[0065] It should be noted that when the detergent intake passage 30a is configured with a uniform cross-section, the cross-sectional area at any portion of the detergent intake passage 30a is the aforementioned minimum cross-sectional area. When the gas intake passage 40a is configured with a uniform cross-sectional area, the cross-sectional area at any portion of the gas intake passage 40a is the aforementioned minimum cross-sectional area.

[0066] It should be noted that the detergent is affected by factors such as surface tension, and the minimum cross-sectional area of ​​the detergent suction channel 30a is not sufficient to allow the first detergent delivery chamber 10a to spontaneously flow into the foam generating component due to its own weight. For example, in some embodiments, the minimum cross-sectional area of ​​the detergent suction channel 30a does not exceed 15mm 2 (square millimeters).

[0067] It should be noted that the minimum cross-sectional area of ​​the gas suction channel 40a is such that the water in the foam generating assembly substantially does not flow out of the gas suction channel 40a.

[0068] In some embodiments, referring to Figures 2 and 3 , the foam generating assembly is positioned adjacent to the first detergent dispensing chamber 10a, with a first partition wall 30 therebetween. In other words, one side surface of the first partition wall 30 serves as a portion of the inner surface of the first detergent dispensing chamber 10a, and the other side surface of the first partition wall 30 serves as a portion of the inner surface of the foam generating assembly. This results in a compact structure.

[0069] The detergent suction channel 30a penetrates the first partition wall 30. This saves processing costs, shortens the length of the detergent suction channel 30a, reduces the flow resistance of the detergent in the detergent suction channel 30a, and facilitates the detergent in the first detergent delivery chamber 10a to be reliably sucked into the foam generating assembly.

[0070] In some embodiments, as shown in FIG3 , a second partition wall 40 is provided between the foam generating assembly and the ambient air. One side of the second partition wall 40 serves as part of the inner surface of the foam generating assembly and is in contact with the air, thereby achieving a compact structure.

[0071] The gas suction channel 40a penetrates the second partition wall 40. In this way, the processing cost is saved, the length of the gas suction channel 40a is shortened, and the flow resistance of the air flowing through the gas suction channel 40a is reduced.

[0072] In some embodiments, referring to FIG. 2 , the lotion dispensing device further includes a mixing chamber 50a having a liquid discharge port 50b . The outlet 201b of the foam generating assembly is connected to the mixing chamber 50a , and the liquid discharge port 50b is used to discharge the liquid in the mixing chamber 50a .

[0073] The liquid in the foam generating assembly enters the mixing chamber 50a through the outlet 201b and is mixed again in the mixing chamber 50a to improve the mixing effect.

[0074] The direction in which the fluid enters the mixing chamber 50a is not limited. For example, the fluid may enter along the extending direction of the mixing chamber 50a.

[0075] In some embodiments, referring to FIG4 , the foam generating assembly extends in a first direction, and the mixing chamber 50a extends in a second direction, wherein the first direction and the second direction intersect and are both perpendicular to the height direction of the detergent dispensing device. In other words, the mixing chamber 50a is placed horizontally, and the fluid needs to undergo a large angle of deflection when flowing from the outlet 201b of the foam generating assembly into the mixing chamber 50a, thereby achieving a better mixing effect. In addition, such an arrangement can also slow down the flow of water, which helps to fully mix the fluid, and can also save the size of the mixing chamber 50a in the height direction, thereby making the detergent dispensing device have a relatively small size in the height direction, which can be used in scenarios where the installation space in the height direction is relatively narrow, for example, suitable for pulsator washing machines.

[0076] In some embodiments, referring to FIG4 , a mixing chamber 50a is provided with drainage ports 50b at opposite ends along its extension direction, with the outlet 201b extending through the sidewall of the mixing chamber 50a in the middle region along its extension direction. This also saves space in the detergent dispensing device, and the two drainage ports 50b increase the discharge rate of the mixed liquid within the mixing chamber 50a.

[0077] In some embodiments, please refer to Figures 2 to 4, the lotion dispensing device includes a main shell 10, a mixing cylinder 50, a first lotion dispensing chamber 10a is arranged in the main shell 10, the foam generating assembly includes a venturi tube 20, the mixing cylinder 50 and the venturi tube 20 are arranged on the bottom side of the main shell 10, the venturi tube 20 extends along a first direction, and the mixing cylinder 50 is connected to one end of the venturi tube 20 and extends along a second direction.

[0078] The space inside the mixing cylinder 50 defines a mixing chamber 50 a , and a sidewall of the mixing chamber 50 a is provided with a liquid discharge port 50 b , which is used to discharge water obliquely downward away from the side where the venturi tube 20 is located.

[0079] In some embodiments, referring to FIG4 , the mixing cylinder 50 includes a first half cylinder 51 and a second half cylinder 52 , which are sealed and butted together along the height direction of the lotion dispenser, thereby reducing the difficulty of manufacturing the mixing cylinder 50 .

[0080] For example, at least a portion of the main housing 10 and the first half-barrel 51 are integrally formed. That is, at least a portion of the main housing 10 and the first half-barrel 51 can be formed together, for example, by integral injection molding. This simplifies the assembly process, saving production costs and improving the sealing of the internal structure.

[0081] Of course, in other embodiments, the mixing cylinder 50 and the main housing 10 are of separate structures.

[0082] In some embodiments, referring to FIG4 , the venturi tube 20 includes a first half tube 21 and a second half tube 22 , which are sealed and butted together along the height direction of the lotion dispenser, thereby reducing the difficulty of manufacturing the venturi tube 20 .

[0083] Exemplarily, at least a portion of the main housing 10 and the first half pipe 21 are an integral structure.

[0084] The present application also provides a clothes processing device, comprising a clothes processing drum, a water supply device and the above-mentioned detergent dispensing device. The water supply device is connected to the inlet 201a of the detergent dispensing device. The clothes processing drum is used to accommodate clothes.

[0085] Before washing clothes, detergent can be added to the first detergent dispensing chamber 10a. After the water supply device supplies water, external air and the detergent in the first detergent dispensing chamber 10a are drawn into the foam generating assembly for mixing and foaming, thereby improving the dissolution and foaming of the detergent, enhancing the cleaning effect of the clothes treatment device, and improving the user experience. The clothes treatment device can be of any type, for example, a pulsator-type clothes treatment device or a drum-type clothes treatment device.

[0086] It is understood that the laundry treatment tub can be a non-porous tub, that is, the laundry treatment tub itself can hold water, and during the washing process, the wash water will not flow outside the laundry treatment tub. The laundry treatment tub can also be a perforated tub, with a water tub provided outside the laundry treatment tub, which relies on the water tub to hold water.

[0087] In some embodiments, the top side of the laundry tub has a clothing inlet, and the detergent dispenser is disposed on the top side of the laundry tub, discharging water through the clothing inlet toward the interior of the laundry tub. In other words, the liquid discharged from the detergent dispenser can be sprayed directly onto the laundry, resulting in a large amount of foam adhering to the laundry, thereby enhancing the cleaning effect.

[0088] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0089] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
