In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.

[0044] In view of this, 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 assembly, a lotion suction channel 30a, and a gas suction channel 40a.

[0045] The first lotion dispensing chamber 10a is used to hold lotion.

[0046] The type of the lotion is not limited. For example, it can be detergent, fabric softener, etc. In the embodiments of the present application, the case where the first lotion dispensing chamber 10a holds detergent is taken as an example for description.

[0047] In some embodiments, please refer to Figure 1 and Figure 2 , the lotion dispensing device further includes a cover plate 101. The top of the first lotion dispensing chamber 10a has a lotion dispensing opening 101a, and the cover plate 101 is used to open or close the lotion dispensing opening 101a. Before washing clothes, the user can pre-dispense a certain amount of lotion into the first lotion dispensing chamber 10a through the lotion dispensing opening 101a. The cover plate 101 can prevent foreign objects from falling into the lotion dispensing opening 101a.

[0048] In some embodiments, please refer to Figure 1 , the lotion dispensing device further includes a second lotion dispensing chamber 10b. The first lotion dispensing chamber 10a and the second lotion dispensing chamber 10b are not connected to each other and are arranged side by side.

[0049] The second lotion dispensing chamber 10b is used to hold lotion.

[0050] Exemplarily, 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.

[0051] It should be noted that the type of detergent in the second detergent delivery chamber 10b may be different from the type of detergent in the first detergent delivery chamber 10a. For example, the first detergent delivery chamber 10a contains detergent, and the second detergent delivery chamber 10b contains disinfectant, softener, perfume, etc.

[0052] Please refer to Figure 1 and Figure 2 The foam generating assembly has an inlet 201a and an outlet 201b, and the inlet 201a is used to connect to the water supply device.

[0053] The water supplied by the water supply device flows into the Venturi passage 20a through the inlet 201a and is discharged through the outlet 201b.

[0054] The water supply device is not limited and can be a water pipe or a water storage mechanism.

[0055] The detergent suction channel 30a communicates with 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.

[0056] The gas suction channel 40a connects the foam generating component and the atmospheric environment, and is used to guide the air to the foam generating component under the action of negative pressure.

[0057] 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 air 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, and the air forms a large number of bubbles in the water flow. The large number of bubbles can promote the dispersion and dissolution of the detergent, and 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 can also reduce the amount of detergent used.

[0058] 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, and sufficient mixing of lotion, water flow and air can be achieved to enhance the foaming effect of the lotion, which is conducive to reducing the cost of the lotion dispensing device.

[0059] For some examples, please refer toFigure 3 The foam generating assembly is a Venturi channel 20a, which includes a converging section 200a, a throat section 200b, and a diverging section 200c connected in sequence. The cross-sectional area of the converging section 200a and the cross-sectional area of the diverging section 200c are both larger than the cross-sectional area of the throat section 200b.

[0060] The above-mentioned Venturi channel 20a refers to a channel that can generate the Venturi effect to create negative pressure inside the foam generating assembly.

[0061] Among them, the detergent inhalation channel 30a penetrates the inner surface of the throat section 200b. That is to say, the detergent inhalation channel 30a is connected to the throat section 200b, and their internal spaces are connected. Therefore, the adsorption effect on the detergent is more obvious, and the detergent can be more easily inhaled into the Venturi channel 20a.

[0062] In some embodiments, the gas inhalation channel 40a penetrates the inner surface of the throat section 200b. Similarly, that is, the gas inhalation channel 40a is connected to the throat section 200b, and their internal spaces are connected. Therefore, the outside air can be more easily inhaled into the Venturi channel 20a, which is beneficial to improving the reliability of the air inhalation of the detergent dispensing device.

[0063] The relative positional relationship between the foam generating assembly and the first detergent dispensing 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, etc.

[0064] Exemplarily, please refer to Figure 2 , the foam generating assembly is located below the first detergent dispensing chamber 10a, and the detergent inhalation channel 30a penetrates the bottom surface of the first detergent dispensing chamber 10a. In this way, under the influence of its own weight, the detergent can more easily enter the detergent inhalation channel 30a. In this way, problems such as air suction or blockage are not likely to occur. In addition, it can also suck out the detergent in the first detergent dispensing chamber 10a as much as possible, so that there is less detergent residue in the first detergent dispensing chamber 10a.

[0065] It should be noted that the relative positional relationship between the part where the detergent inhalation channel 30a penetrates the inner surface of the foam generating assembly and the part where the gas inhalation channel 40a penetrates the inner surface of the foam generating assembly is not limited.

[0066] Exemplarily, please refer to Figure 2 and Figure 3, the part of the gas inhalation channel 40a passing through the foam generating assembly and the part of the lotion inhalation channel 30a passing through the foam generating assembly are arranged along the same straight line. That is to say, the above two parts are arranged facing each other. In this way, the gas inhaled into the foam generating assembly from the gas inhalation channel 40a and the lotion inhaled into the foam generating assembly from the lotion inhalation channel 30a can impact each other, achieving a better mixing and foaming effect.

[0067] In some embodiments, please refer to Figure 2 and Figure 3 , the minimum cross-sectional area of the lotion inhalation channel 30a is smaller than the minimum cross-sectional area of the gas inhalation channel 40a. Then, within a unit time, the amount of air introduced into the foam generating assembly through the gas inhalation channel 40a is greater than the amount of lotion introduced into the foam generating assembly through the lotion inhalation channel 30a. Increasing the amount of air entering can make the lotion dissolve more thoroughly in the water flow and foam more fully.

[0068] Among them, the minimum cross-sectional area of the lotion inhalation channel 30a refers to the one with the smallest cross-sectional area among all cross-sections perpendicular to the lotion flow direction. The minimum cross-sectional area of the gas inhalation channel 40a refers to the one with the smallest cross-sectional area among all cross-sections perpendicular to the air flow direction.

[0069] The lotion inhalation channel 30a can be set with a constant cross-section or a variable cross-section. The gas inhalation channel 40a can be set with a constant cross-section or a variable cross-section.

[0070] It should be noted that when the lotion inhalation channel 30a is set with a constant cross-section, the cross-sectional area at any part of the lotion inhalation channel 30a is the above-mentioned minimum cross-sectional area. When the gas inhalation channel 40a is set with a constant cross-section, the cross-sectional area at any part of the gas inhalation channel 40a is the above-mentioned minimum cross-sectional area.

[0071] It should be noted that due to factors such as surface tension, the minimum cross-sectional area of the lotion inhalation channel 30a is not sufficient to cause a large amount of the first lotion delivery chamber 10a to spontaneously flow into the foam generating assembly due to its own weight. For example, in some embodiments, the minimum cross-sectional area of the lotion inhalation channel 30a does not exceed 15 mm 2 (square millimeters).

[0072] It should be noted that the minimum cross-sectional area of the gas inhalation channel 40a is such that the water liquid in the foam generating assembly basically does not flow out through the gas inhalation channel 40a.

[0073] In some embodiments, please refer to Figure 2 and Figure 3, the foam generating assembly is arranged adjacent to the first detergent dispensing chamber 10a, and there is a first partition wall 30 between them. That is to say, one side surface of the first partition wall 30 serves as a part of the inner surface of the first detergent dispensing chamber 10a, and one side surface of the first partition wall 30 serves as a part of the inner surface of the foam generating assembly. In this way, the structure can be made compact.

[0074] The detergent suction channel 30a penetrates through the first partition wall 30. This not only saves processing costs but also 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 reliable suction of the detergent in the first detergent dispensing chamber 10a into the foam generating assembly.

[0075] In some embodiments, please refer to Figure 3 , there is a second partition wall 40 between the foam generating assembly and the atmospheric environment. One side surface of the second partition wall 40 serves as a part of the inner surface of the foam generating assembly, and one side surface of the second partition wall 40 is in contact with the air. In this way, the structure can be made compact.

[0076] The gas suction channel 40a penetrates through the second partition wall 40. In this way, it not only saves processing costs but also shortens the length of the gas suction channel 40a and reduces the flow resistance of the air flowing through the gas suction channel 40a.

[0077] In some embodiments, please refer to Figure 2 , the detergent dispensing device further includes a mixing chamber 50a. The mixing chamber has a liquid discharge port 50b. The outlet 201b of the foam generating assembly is communicated with the mixing chamber 50a, and the liquid discharge port 50b is used to discharge the liquid in the mixing chamber 50a.

[0078] 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.

[0079] The direction of the fluid entering the mixing chamber 50a is not limited. For example, it can enter along the extending direction of the mixing chamber 50a.

[0080] In some embodiments, please refer to Figure 4 , the foam generating assembly extends along a first direction, and the mixing chamber 50a extends along a second direction, where the first direction and the second direction intersect and are both perpendicular to the height direction of the detergent dispensing device. That is to say, the mixing chamber 50a is placed horizontally. When the fluid flows into the mixing chamber 50a from the outlet 201b of the foam generating assembly, it needs to undergo a large-angle turn, which can achieve a better mixing effect. In addition, such an arrangement can also slow down the water flow, contribute to sufficient mixing, and save the size of the mixing chamber 50a in the height direction, so that the detergent dispensing device has a relatively small size in the height direction and can be applicable to scenarios where the installation space in the height direction is relatively narrow. For example, it is applicable to a pulsator washing machine.

[0081] In some embodiments, please refer to Figure 4 , drain ports 50b are provided at opposite ends of the mixing chamber 50a along its extending direction, and the outlet 201b penetrates through the side wall of the middle region of the mixing chamber 50a along its extending direction. In this way, the space occupied by the detergent dispensing device is also saved, and the two drain ports 50b can increase the discharge speed of the mixed liquid in the mixing chamber 50a.

[0082] In some embodiments, please refer to Figures 2 to 4 , the detergent dispensing device includes a main housing 10 and a mixing cylinder 50. The first detergent dispensing chamber 10a is provided in the main housing 10. The foam generating assembly includes a venturi tube 20. The mixing cylinder 50 and the venturi tube 20 are provided at the bottom side of the main housing 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.

[0083] The space inside the mixing cylinder 50 defines a mixing chamber 50a. The side wall of the mixing chamber 50a is provided with a drain port 50b, and the drain port 50b is used for discharging water obliquely downward toward the side away from the venturi tube 20.

[0084] In some embodiments, please refer to Figure 4 , the mixing cylinder 50 includes a first half cylinder 51 and a second half cylinder 52, and the first half cylinder 51 and the second half cylinder 52 are hermetically butted along the height direction of the detergent dispensing device. In this way, the manufacturing difficulty of the mixing cylinder 50 can be reduced.

[0085] Exemplarily, at least a part of the main housing 10 and the first half cylinder 51 are of an integral structure. That is to say, at least a part of the main housing 10 can be processed and formed together with the first half cylinder 51. For example, they are integrally injection molded. In this way, the assembly process can be simplified, which is beneficial to both saving production costs and improving the sealing performance of the internal structure.

[0086] Of course, in other embodiments, the mixing cylinder 50 as a whole is a split structure with the main housing 10.

[0087] In some embodiments, please refer to Figure 4 , the venturi tube 20 includes a first half tube 21 and a second half tube 22, and the first half tube 21 and the second half tube 22 are hermetically butted along the height direction of the detergent dispensing device. In this way, the manufacturing difficulty of the venturi tube 20 can be reduced.

[0088] Exemplarily, at least a part of the main housing 10 and the first half tube 21 are of an integral structure.

[0089] The present application further provides a laundry treatment device, including a laundry treatment drum, a water supply device, and the above-mentioned detergent dispensing device. Among them, the water supply device is connected to the inlet 201a of the detergent dispensing device. The laundry treatment drum is used to accommodate laundry.

[0090] Before washing the laundry, detergent can be dispensed into the first detergent dispensing chamber 10a. After the water supply device supplies water, the external air and the detergent in the first detergent dispensing chamber 10a are sucked into the foam generating assembly for mixing and foaming, which improves the dissolution effect and foaming degree of the detergent, enhances the cleaning effect of the laundry treatment device, and improves the user experience. The type of the laundry treatment device is not limited. For example, it can be a pulsator-type laundry treatment device or a drum-type laundry treatment device.

[0091] It can be understood that the laundry treatment drum can be a non-porous drum, that is, the laundry treatment drum itself can hold water, and during the washing process, the washing water will not flow to the outside of the laundry treatment drum. The laundry treatment drum can also be a porous drum, and a water storage bucket is provided outside the laundry treatment drum to hold water by relying on the water storage bucket.

[0092] In some embodiments, the top side of the laundry treatment drum has a laundry loading opening, and the detergent dispensing device is arranged on the top side of the laundry treatment drum and can discharge water towards the internal space of the laundry treatment drum through the laundry loading opening. That is to say, the liquid discharged from the detergent dispensing device can be directly sprayed on the laundry, so that a large amount of foam adheres to the laundry, improving the cleaning effect.

[0093] The various embodiments / implementation manners provided in the present application can be combined with each other without contradiction.

[0094] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
