[0066] In some embodiments, in combination with FIG. 1 and FIG. 2, the liquid storage member 200 is a liquid storage bottle 200, which can be taken out of the liquid separation chamber 110, and by taking out or putting into the liquid separation chamber 110 as a whole, the liquid storage bottle 200 can be replaced as a whole when the detergent in the liquid storage bottle 200 is exhausted or almost exhausted, or the empty liquid storage bottle 200 can be refilled with detergent and then put into the liquid separation chamber 110, wherein the liquid storage bottle 200 is also provided with a gas permeable through hole 230, and it should be noted that in order to reduce the possibility of detergent leakage in the liquid storage bottle 200, the liquid storage bottle 200 is a closed structure at positions other than the second through hole 220, and in the state that the liquid inlet end of the liquid pump 400 is communicated with the second through hole 220, the liquid storage chamber 210 forms a closed cavity, as the liquid pump 400 continuously pumps out the detergent in the liquid storage chamber 210, the air pressure in the liquid storage chamber 210 continues to decrease, thereby increasing the difficulty of the liquid pump 400 to pump out the detergent in the liquid storage chamber 210, by setting the gas permeable through hole 230, the liquid storage chamber 210 can be communicated with the atmosphere through the gas permeable through hole 230, so as to keep the air pressure in the liquid storage chamber 210 balanced, thereby enabling the liquid pump 400 to continuously pump out the detergent from the liquid storage chamber 210.

Exemplarily, the gas permeable valve can be a one-way valve 260, and the specific installation manner of the gas permeable valve in the gas permeable through hole 230 can be similar to the installation manner of the one-way valve 260 in the second through hole 220.

[0067] Meanwhile, in combination with FIG. 3 and FIG. 4, the liquid dispensing device 10 further comprises a liquid suction connector 300, a liquid suction pipe 500 and a liquid return pipe 600. The liquid suction connector 300 is detachably connected with the distribution box 100, the liquid suction connector 300 comprises a tubular part 310, a first end of the tubular part 310 is located outside the distribution box 100, and a second end of the tubular part 310 opposite to the first end is extended into the second through hole 220 by the first through hole 120, the second end of the tubular part 310 is extended along the first direction and can be communicated with the second through hole 220, it can be understood that in the state that the liquid storage bottle 200 is installed inside the distribution box 100, the second end of the liquid suction connector 300 can be extended into the second through hole 220 so as to make the liquid suction connector 300 communicated with the liquid storage cavity 210, thereby making the liquid suction connector 300 capable of sucking the detergent in the liquid storage cavity 210 to the outside of the distribution box 100. It can be understood that the liquid suction connector 300 can be detachably connected with the distribution box 100 by various ways, for example, the liquid suction connector 300 can be detachably connected with the distribution box 100 by a first connecting structure 330, for example, the tubular part 310 can be detachably connected with the distribution box 100 by interference fit with the first through hole 120. The liquid suction pipe 500 is communicated with the liquid suction pump 400 and the first end of the tubular part 310, the liquid suction pump 400 is communicated with the liquid storage cavity 210 through the liquid suction pipe 500 and the tubular part 310, thereby capable of sucking the detergent in the liquid storage cavity 210, the liquid return pipe 600 is communicated with the liquid suction pump 400 and the liquid inlet 150, the liquid suction pump 400 arranged outside the distribution box 100 is capable of inputting the detergent from the liquid inlet 150 into the distribution cavity 110 through the liquid return pipe 600. By arranging the liquid suction pump 400 outside the distribution box 100 and detachably connecting the liquid suction pump 400 with the distribution box 100 through the liquid suction connector 300 and the liquid suction pipe 500, compared with the structure that the shell of the liquid suction pump 400 is integrated with the rear part of the shell of the distribution box 100, in the case that the liquid suction pump 400 needs to be repaired or replaced, the liquid suction pump 400 can be more conveniently detached, thereby improving the convenience of repairing and maintaining the liquid dispensing device 10, meanwhile, by arranging the liquid suction pump 400 outside the distribution box 100 and connecting the liquid suction pump 400 with the liquid suction connector 300 through the liquid suction pipe 500, in the case that the shape or appearance of the distribution box 100 is changed, the liquid suction pump 400 can still be applied to the distribution box 100, thereby improving the versatility of the liquid suction pump 400, and the liquid suction pipe 500 is also exposed outside the distribution box 100, thereby capable of arranging a sensor outside the liquid suction pipe 500, through the sensor, the liquid dispensing device 10 can realize more functions, for example, by arranging a light transmittance sensor 902, the size or density of the bubbles in the liquid suction pipe 500 can be obtained, thereby realizing the detection of the detergent amount in the liquid storage cavity 210, for example, by arranging a temperature sensor, the temperature of the detergent can be obtained.

[0068] In some embodiments, as shown in FIG. 5, the liquid extraction connector 300 further comprises a first connecting structure 330 on the outer periphery of the tubular part 310, which is detachably fixed to the outer surface of the liquid distribution box 100 by a connecting member. By providing the first connecting structure 330, more mounting space can be provided for the connecting member, so that the liquid extraction connector 300 can be more conveniently and detachably connected to the liquid distribution box 100. Optionally, the first connecting structure 330 can be provided with a through hole, the outer surface of the liquid distribution box 100 has a threaded hole corresponding to the through hole, and the connecting member is a screw. By passing the screw through the through hole and screwing it into the threaded hole, the liquid extraction connector 300 can be detachably connected to the liquid distribution box 100.

[0069] In some embodiments, in combination with FIGS. 3 and 4, the outer surface of the liquid distribution box 100 is recessed to form a first recess 170, and the inner surface of the liquid distribution box 100 is correspondingly protruded to form a first protrusion 140. It can be understood that the first recess 170 can be formed on the outer surface of the liquid distribution box 100 by mechanical processing such as stamping, so that the first recess 170 can be formed without reducing the wall thickness of the liquid distribution box 100, so that the liquid distribution box 100 has sufficient structural strength; a first through hole 120 is provided at the first recess 170, and the first connecting structure 330 is detachably fixed in the first recess 170 of the liquid distribution box 100 by a connecting member. By accommodating the first connecting structure 330 in the first recess 170, the first connecting structure 330 and part of the tubular part 310 can be accommodated inside the first recess 170, so as to reduce the volume of the liquid extraction connector 300 protruding outside the liquid distribution box 100, thereby reducing the possibility of interference between other parts or structures of the liquid delivery device 10 and the liquid extraction connector 300. Moreover, the part of the first connecting structure 330 that needs to be connected to the outer surface of the liquid distribution box 100 forms a mating surface, which has a higher requirement for machining precision. If the entire outer surface of the liquid distribution box 100 is used as the mating surface, the machining cost and difficulty will be increased. By providing the first recess 170 and detachably connecting the first connecting structure 330 to the inner surface of the first recess 170, the inner surface of the first recess 170 is used as the mating surface and the outer surface of the remaining part of the liquid distribution box 100 is used as a non-mating surface, thereby reducing the machining cost and difficulty of the liquid distribution box 100.

[0073] In some embodiments, as shown in FIG. 7, the suction pipe 700 comprises a first tubular part 720 and a second tubular part 730, the second tubular part 730 protruding from the outer surface of the first tubular part 720, thereby forming two non-parallel parts, so that the second tubular part 730 can extend towards the bottom of the liquid storage cavity 210 while the extension direction of the first tubular part 720 is parallel to the first direction, thereby enabling the second end of the suction pipe 700 to be closer to the bottom of the liquid storage cavity 210 while facilitating the installation of the suction pipe 700, so that the suction pipe 700 can extract more detergent; wherein the end of the first tubular part 720 forms the first end of the suction pipe 700, the first tubular part 720 communicates with the second through hole 220 through the first end of the suction pipe 700, the second tubular part 730 extends towards the bottom surface of the liquid storage cavity 210, and the end of the second tubular part 730 towards the bottom surface of the liquid storage cavity 210 forms the second end of the suction pipe 700, the second end of the suction pipe 700 having a suction port 741. Optionally, the second tubular part 730 protrudes from the end of the first tubular part 720 away from the first end of the suction pipe 700, thereby forming a tubular structure similar to an L shape; optionally, the second tubular part 730 protrudes from the outer surface of the side wall of the first tubular part 720 close to the end, thereby forming a cross pipe.

[0074] Optionally, as shown in FIG. 7, the suction pipe 700 further comprises a base 710, the base 710 being located at the first end of the suction pipe 700 and protruding from the first tubular part 720, a communication hole being formed in the base 710, the first end of the suction pipe 700 communicating with the second through hole 220 through the communication hole, the base 710 extending into the space surrounded by the annular wall 252 and being capable of abutting against the inner surface of the annular wall 252, thereby further achieving the circumferential positioning of the suction pipe 700.

[0075] In some embodiments, in combination with FIGS. 7 and 8, the liquid storage bottle 200 further comprises a one-way valve 260, the one-way valve 260 being located in the second through hole 220 and blocking the second through hole 220, for allowing the detergent to flow out and preventing the detergent from flowing back, specifically, the inner surface of the second through hole 220 protrudes an annular positioning boss, one end of the one-way valve 260 being accommodated in the space surrounded by the annular wall 252 and abutting against the annular positioning boss, the other end of the one-way valve 260 being accommodated in the interior of the first tubular part 720 and abutting against the inner surface of the first tubular part 720, it can be understood that the one-way valve 260 is radially positioned by the inner surface of the first tubular part 720 and the inner surface of the annular wall 252, at the same time, the one-way valve 260 is clamped between the annular positioning boss and the inner surface of the first tubular part 720, thereby achieving the axial positioning of the one-way valve 260.

[0076] It can be understood that the second through hole 220 is a long hole, the first end of the first tubular part 720 of the suction pipe 700 is inserted into the second through hole 220 from one direction, and the second end of the tubular part 310 of the liquid suction connector 300 is inserted into the annular wall 252 from the other direction. The annular wall 252 is provided with an annular positioning boss on the inner surface, and the one-way valve 260 is clamped between the annular positioning boss and the inner surface of the first tubular part 720.

[0077] In some embodiments, as shown in FIG. 9, the second end of the suction pipe 700 is provided with an abutting boss 750, the abutting boss 750 is protruded from the second end of the suction pipe 700 to the bottom surface of the liquid storage cavity 210 to form an abutting end 751, and the abutting end 751 abuts the bottom surface of the liquid storage cavity 210. It can be understood that, due to the long length of the suction pipe 700 protruding out of the inner surface of the liquid storage bottle 200, a long cantilever structure is formed, which may cause the suction pipe 700 to swing in the vertical direction under its own action. By providing the abutting boss 750 at the second end of the suction pipe 700 and abutting the bottom surface of the liquid storage cavity 210, the suction pipe 700 is supported at both ends by the annular wall 252 and the abutting boss 750, thereby limiting the swing of the suction pipe 700 in the vertical direction, and the installation of the suction pipe 700 is more stable.

[0078] Among them, the number of abutting bosses 750 is greater than or equal to three, and each abutting boss 750 is arranged at intervals around the suction port 741, so that the abutting positions of the three abutting bosses 750 and the bottom surface of the liquid storage cavity 210 are in non-collinear positions, that is, a support surface is formed by three non-collinear support positions to support the suction pipe 700 more reliably, and multiple abutting bosses 750 are arranged at intervals to support the suction pipe 700, so that the detergent can enter the suction port 741 from the gap between adjacent abutting bosses 750, that is, while reducing the influence of the suction port 741 on the suction of the detergent, the support of the suction pipe 700 is realized.

[0079] Optionally, as shown in FIG. 9, the cross-sectional area of the abutting boss 750 decreases in the extension direction of the abutting boss 750, that is, from the second end of the suction pipe 700 to the bottom surface of the liquid storage cavity 210. The cross section is a plane perpendicular to the extension direction of the abutting boss 750. It can be understood that the abutting boss 750 gradually shrinks while extending towards the bottom surface of the liquid storage cavity 210, thereby further reducing the obstruction of the abutting boss 750 to the suction port 741.

[0080] In some embodiments, as shown in FIG. 10, the bottom surface of the liquid storage cavity 210 is concave to form a second recess 243, and the second end of the suction pipe 700 extends into the second recess 243 to enable the suction pipe 700 to draw more detergent. Meanwhile, the second end of the suction pipe 700 is further provided with an abutting boss 750, which is formed by the second end of the suction pipe 700 extending outward to form an abutting end 751 that abuts the bottom surface of the second recess 243, so that the suction pipe 700 is more stably supported while being able to draw more detergent.

[0081] In some embodiments, as shown in FIG. 11, the liquid storage member 200 is a liquid storage bottle 200, and the liquid dispensing device 10 further comprises a liquid storage bottle holder 900, which forms an accommodation space 910 inside. In the first direction, the liquid storage bottle holder 900 can move relative to the distribution box 100, so that the liquid storage bottle 200 can slide relative to the distribution box 100 in the first direction. That is, the liquid storage bottle 200 can slide relative to the distribution box 100 through the liquid storage bottle holder 900. By providing the liquid storage bottle holder 900, it is convenient to slide the liquid storage bottle 200, and when there are multiple liquid storage bottles 200, each liquid storage bottle 200 can be arranged in a liquid storage bottle holder 900, and each liquid storage bottle 200 can be moved relative to the distribution box 100 in the first direction at the same time through the liquid storage bottle holder 900. The liquid storage bottle holder 900 can be pulled out of the distribution cavity 110 in the first direction, and the second end of the tubular portion 310 extends in the first direction, so that the second end of the tubular portion 310 can extend into the second through hole 220 and communicate with the suction pipe 700 while the liquid storage bottle holder 900 slides in the first direction.

[0082] In the first direction, the liquid storage bottle holder 900 has a first end close to the bottle cap 250 and a second end opposite to the first end. The first end of the liquid storage bottle holder 900 is provided with a third through hole 920. In the state that the liquid storage bottle 200 is accommodated in the accommodation space 910, the bottle cap 250 extends into the distribution cavity 110 through the third through hole 920, so that the second end of the tubular portion 310 can more conveniently extend into the second through hole 220 arranged in the bottle cap 250.

[0083] In the state that the liquid storage bottle holder 900 is pulled out of the distribution cavity 110, the liquid storage bottle 200 can be taken out of or put into the accommodation space 910. It can be understood that in the state that the liquid storage bottle holder 900 is pulled out of the distribution cavity 110, the opening of the liquid storage bottle holder 900 is exposed to the outside of the liquid dispensing device 10, so that the liquid storage bottle 200 can be put into or taken out of the accommodation space 910 as a whole through the opening.

[0084] Optionally, as shown in FIG. 11, the third through hole 920 extends to the bottom surface of the containing space 910, and during the process of loading the liquid storage bottle 200, the bottle cap 250 can be extended into the third through hole 920 and located close to the bottom of the containing space 910, i.e., the liquid storage bottle 200 is in an inclined state with the bottle cap 250 being low and the bottle body 240 being high, so as to facilitate the installation of the liquid storage bottle 200, and then the end of the bottle body 240 is pressed into the containing space 910, at this time, the bottle cap 250 moves in the third through hole 920 away from the bottom surface of the containing space 910, so that the liquid storage bottle 200 can be in a horizontal state and be loaded into the containing space 910.

[0085] In some embodiments, as shown in FIG. 12, the outer surface of the bottom wall of the liquid storage bottle rack 900 has a guide groove 963, and the inner surface of the bottom wall of the dispensing box 100 has a guide rail 112, in the assembled state of the liquid storage bottle rack 900 and the dispensing box 100, the guide rail 112 is located in the guide groove 963, the guide groove 963 extends in the first direction, and the guide rail 112 can move in the guide groove 963 in the first direction, it can be understood that through the action force between the guide rail 112 and the guide groove 963, the movement between the liquid storage bottle rack 900 and the dispensing box 100 in directions other than the first direction is limited, i.e., the guiding of the liquid storage bottle rack 900 is achieved.

[0086] In some embodiments, as shown in FIG. 13, the second end of the liquid storage bottle rack 900 has a resilient arm 931, and the projection of the inner surface of the first end of the liquid storage bottle rack 900 is located in the third through hole 920, and the resilient arm 931 can be elastically deformed in the first direction, it can be understood that in the state that the liquid storage bottle 200 is located in the containing space 910, the resilient arm 931 abuts against one end of the liquid storage bottle 200 and pushes the liquid storage bottle 200 towards the first end of the liquid storage bottle rack 900, so that the other end of the liquid storage bottle 200 abuts against the inner surface of the first end of the liquid storage bottle rack 900, so that the two ends of the liquid storage bottle 200 are clamped by the resilient arm 931 and the inner surface of the first end of the liquid storage bottle rack 900, and the liquid storage bottle 200 is reliably contained in the containing space 910, and when the liquid storage bottle 200 is taken out of the containing space 910 or loaded into the containing space 910, the liquid storage bottle 200 can be avoided by the elastic deformation of the resilient arm 931, so that the liquid storage bottle 200 is more easily loaded into the containing space 910 or taken out of the containing space 910.

[0087] Optionally, as shown in FIG. 13, the side surface of the liquid storage bottle rack 900 close to the second end of the liquid storage bottle rack 900 is provided with an operation groove 940. In order to make full use of the storage space 910, it is necessary to make the liquid storage bottle 200 substantially occupy the storage space 910, so that the distance between the liquid storage bottle 200 and the inner wall of the storage space 910 is small, which causes that in the state of taking out the liquid storage bottle 200 from the storage space 910, the user's hand is difficult to stretch into the inner wall of the storage space 910 and the liquid storage bottle 200, and the liquid storage bottle 200 is difficult to be taken out. By setting the operation groove 940, the user's hand can be stretched into the storage space 910 through the operation groove 940 and the part of the liquid storage bottle 200 close to the second end of the liquid storage bottle rack 900 is lifted, so that the liquid storage bottle 200 is conveniently taken out from the storage space 910.

[0088] In some embodiments, as shown in FIG. 14, the bottom surface of the liquid storage cavity 210 is concave to form a second groove 243, and a third protrusion 244 is formed at the corresponding position of the outer surface of the bottle body 240. The inner surface of the liquid storage bottle rack 900 is concave to form a third groove 901, the third groove 901 extends along the first direction, and in the first direction, the size D1 of the third protrusion 244 is smaller than the size D2 of the third groove 901. In the state that the liquid storage bottle 200 is located in the storage space 910, the third protrusion 244 is located in the third groove 901. It can be understood that the liquid storage bottle 200 is formed by stamping or injection molding to form the second groove 243 and the corresponding third protrusion 244 at the corresponding position of the outer surface of the liquid storage bottle 200. By setting the third groove 901 to avoid the third protrusion 244, and by making the size D1 of the third protrusion 244 smaller than the size D2 of the third groove 901 in the first direction, the third protrusion 244 can slide in the third groove 901 along the first direction during the installation or removal of the liquid storage bottle 200, thereby reducing the possibility of movement interference between the third protrusion 244 and the third groove 901.

[0089] In some embodiments, as shown in FIG. 15, the liquid dispensing device 10 further comprises a Venturi tube 800, and the liquid distribution box 100 further comprises a second liquid outlet 160. The Venturi tube 800 comprises a Venturi tube body 820 and a funnel structure 830. One end of the Venturi tube body 820 is a water inlet, and the other end of the Venturi tube body 820 is a water outlet. The diameter of the Venturi tube body 820 decreases in the direction from the one end to the other end, thereby forming a converging section. A throat is formed at a position close to the other end of the converging section. The funnel structure 830 is connected to the converging section close to the throat. The end of the funnel structure 830 away from the Venturi tube body 820 has the largest opening and forms a negative pressure suction port 810. A negative pressure is formed in the converging section during the flow of water from the water inlet to the water outlet, thereby forming a suction force at the negative pressure suction port 810. The second liquid outlet 160 is in communication with the negative pressure suction port 810, so that the Venturi tube 800 can draw the detergent in the liquid distribution chamber 110 out through the second liquid outlet 160 and mix it with water to form a multi-bubble washing mixture, and can spray the washing mixture into the washing drum 30, thereby improving the washing efficiency. The detergent can include different types. By controlling the distance between the liquid inlet 150 and the second liquid outlet 160, the proportion of the detergent in the washing mixture can be controlled. The relevant structures of the liquid inlet 150 and the second liquid outlet 160 are described below.

[0090] In combination with FIGS. 3 and 15, the number of the first through holes 120, the second through holes 220, the liquid inlets 150, the suction tubes 700, and the liquid storage bottles 200 is two. The liquid inlet end of the liquid pump 400 and the liquid outlet end of the liquid pump 400 each has two. The liquid inlet ends of the two liquid pumps 400 pass through the two first through holes 120 and can respectively communicate with the two second through holes 220. The two suction tubes 700 are respectively located in the two liquid storage bottles 200 and communicate with the two second through holes 220. The two liquid outlet ends of the liquid pump 400 respectively communicate with the two liquid inlets 150. It can be understood that the two first through holes 120, the second through holes 220, the liquid inlets 150, and the suction tubes 700 are respectively connected in communication, thereby forming two independent flow channels.

[0091] Two liquid storage bottles 200 form a first cavity and a second cavity respectively, that is, the liquid storage cavities 210 in the liquid storage bottles 200 form a first cavity and a second cavity respectively, the first cavity is used to contain a main washing agent, the main function of the main washing agent is to clean clothes, the second cavity is used to contain an auxiliary washing agent, the function of the auxiliary washing agent is to assist in cleaning clothes or to achieve other functions, for example, the auxiliary washing agent can be a special washing agent for cleaning a specific type of dirt, for example, the auxiliary washing agent can be a softener for making clothes more soft. Among them, two liquid inlets 150 form a first liquid inlet 151 and a second liquid inlet 152 respectively, the first liquid inlet 151 communicates with the first cavity, and the second liquid inlet 152 communicates with the second cavity. It can be understood that the first cavity and the first liquid inlet 151 are communicated through two independent liquid flow channels, and the second cavity and the second liquid inlet 152 are communicated through two independent liquid flow channels, so that the main washing agent and the auxiliary washing agent in the first cavity and the second cavity do not affect each other in the process of flowing. At the same time, the distance between the first liquid inlet 151 and the second liquid outlet 160 is smaller than the distance between the second liquid inlet 152 and the second liquid outlet 160, which can enable the negative pressure suction port 810 to suck in more main washing agent, so as to increase the proportion of the main washing agent in the washing mixed liquid output by the Venturi tube 800, and further improve the cleaning effect on clothes.

[0092] In some embodiments, as shown in FIG. 16, the outer surface of the bottom surface of the liquid distribution box 100 is convexly provided with a guide cylinder 162, the guide cylinder 162 has no bottom surface and only has a side surface, one end of the guide cylinder 162 communicates with the bottom surface of the liquid distribution box 100, and the communication portion is a second liquid outlet 160 for guiding the washing mixed liquid out of the liquid distribution box 100, and the other end communicates with the negative pressure suction port 810 of the Venturi tube 800.

[0093] In some embodiments, as shown in FIG. 16, the outer surface of the bottom surface of the liquid distribution box 100 is convexly provided with a guide cylinder 162 having a bottom surface and a side surface, the guide cylinder 162 protrudes from the bottom surface of the liquid distribution box 100 in a direction parallel to the thickness of the bottom surface of the liquid distribution box 100 and in a direction perpendicular to the thickness of the bottom surface of the liquid distribution box 100, a liquid outlet passage 161 is formed in the guide cylinder 162, the liquid outlet passage 161 communicates with the liquid distribution cavity 110, and one end of the liquid outlet passage 161 that communicates with the liquid distribution cavity 110 forms a second liquid outlet 160. It can be understood that the guide cylinder 162 not only protrudes from the liquid distribution box 100 in the thickness direction of the bottom surface of the liquid distribution box 100, but also protrudes laterally from the bottom surface of the liquid distribution box 100 in a direction perpendicular to the thickness direction, so that the guide cylinder 162 is not located directly below the liquid distribution box 100, but is biased in a direction away from the liquid distribution box 100 in the lateral direction, so that the guide cylinder 162 and the Venturi tube 800 can avoid other parts of the liquid dropping device 10 at the bottom of the liquid distribution box 100, for example, the other parts can be pipelines or wire harnesses.

[0094] The guide cylinder 162 is biased in the lateral direction away from the separation box 100, and the second liquid outlet 160 can only be opened in the overlapping area of the projection of the guide cylinder 162 on the bottom surface of the separation box 100 and the bottom surface of the separation box 100. Therefore, the second liquid outlet 160 is not completely coaxial with the guide cylinder 162, and in the thickness direction perpendicular to the bottom surface of the separation box 100, the second liquid outlet 160 is biased to the side close to the separation box 100 compared with the guide cylinder 162. At the same time, since the guide cylinder 162 is biased in the lateral direction away from the separation box 100, part of the guide cylinder 162 cannot use the bottom surface of the separation box 100 as the bottom surface, but has its own independent bottom surface. The second liquid outlet 160 can be opened on the side or bottom surface of the guide cylinder 162, and in order to obtain a larger second liquid outlet 160, the second liquid outlet 160 can be opened on the side and bottom surface of the guide cylinder 162. In this way, the communication area of the second liquid outlet 160 with the separation cavity 110 is increased, so that more detergent can flow out of the separation cavity 110 through the second liquid outlet 160.

[0095] Moreover, in the thickness direction parallel to the bottom surface of the separation box 100, the part of the funnel-shaped structure 830 close to the negative pressure suction port 810 close to the separation box 100 is located in the side of the guide cylinder 162 away from the separation box 100, so that the communication between the negative pressure suction port 810 and the second liquid outlet 160 is more reliable.

[0096] Optionally, as shown in FIG. 17, the outer surface of the bottom surface of the separation box 100 further protrudes a mounting plate, which extends in the thickness direction perpendicular to the bottom surface of the separation box 100. In the thickness direction parallel to the bottom surface, part of the guide cylinder 162 protrudes from the outer surface of the bottom surface of the separation box 100, and another part protrudes from the outer surface of the mounting plate. The second liquid outlet 160 is located on the outer surface of the separation box 100 and the mounting plate to form at least part of the bottom surface of the guide cylinder 162.

[0097] In some embodiments, in combination with FIGS. 17 and 18, the Venturi tube 800 is fixedly connected with the separation box 100. Specifically, on the outer surface of the separation box 100, the outer periphery of the guide cylinder 162 protrudes outwardly by at least one mounting cylinder 163 and at least one positioning column 164. The Venturi tube 800 further comprises a second connecting structure 821 located on the side wall of the Venturi tube body 820. The second connecting structure 821 is provided with a mounting hole 822 and a positioning hole 823. The positioning column 164 can pass through the positioning hole 823 and make the mounting hole 822 coaxial with the mounting cylinder 163. The mounting hole 822 can be detachably connected with the mounting cylinder 163 through a connecting piece. It can be understood that by providing the second connecting structure 821 on the side wall of the Venturi tube body 820, the connecting piece has a larger operation space.

[0098] In some embodiments, as shown in FIG. 19, the liquid distribution box 100 comprises a liquid distribution box body 181, a liquid distribution box cover 182 and a top cover 183, the liquid distribution box body 181 is fixedly connected with the liquid distribution box cover 182, and the liquid distribution box body 181 and the liquid distribution box cover 182 enclose a liquid distribution cavity 110. The side of the liquid distribution box cover 182 away from the liquid distribution cavity 110 is provided with a convex wall 1821, the top cover 183 is fixedly connected with the convex wall 1821, and the convex wall 1821 and the top cover 183 enclose a condensation cavity 184; and / or, the side of the top cover 183 facing the liquid distribution cavity 110 is provided with a convex wall 1821, the liquid distribution box cover 182 is fixedly connected with the convex wall 1821, and the convex wall 1821 and the liquid distribution box cover 182 enclose the condensation cavity 184; wherein, the liquid distribution box cover 182 further encloses a gas pressure balance channel 186 with the top cover 183, the gas pressure balance channel 186 is communicated with the washing drum 30 through a gas pressure balance pipe 187, the gas pressure balance channel 186 is communicated with the condensation cavity 184, and is used for condensing the moisture in the humid hot air entering the condensation cavity 184 through the gas pressure balance pipe 187. It should be noted that if the washing drum 30 forms a closed cavity when water is injected into the washing drum 30, the gas pressure in the washing drum 30 will continuously increase, which will eventually lead to difficulty or even inability to continue water injection. The washing drum 30 needs to be communicated with the space where the liquid delivery device 10 is located through the gas pressure balance pipe 187, so that the humid air in the washing drum 30 will enter the space where the liquid delivery device 10 is located. In the state of drying the washing drum 30, the humid hot air communicates the washing drum 30 with the space where the liquid delivery device 10 is located through the gas pressure balance pipe 187, and in this state, the amount of water vapor in the air is larger. If the humid air directly enters the space where the liquid delivery device 10 is located, the water vapor in the humid air will form liquid droplets after condensation in the entire space. If the liquid droplets adhere to the outer surface of the liquid storage member 200, these liquid droplets will drop to the ground or the user's body when the user pulls out the liquid storage member 200, which will reduce the user's experience.

[0099] By forming the condensation cavity 184 between the separation box cover 182 and the top cover 183, and making the air pressure balance pipe 187 communicate with the condensation cavity 184 through the air pressure balance channel 186, in the first direction (the first direction is shown by the arrow in FIG. 13), the air pressure balance channel 186 is located on the side of the separation box 100 away from the liquid storage member 200, the condensation cavity 184 is located on the side of the separation box cover 182 close to the air pressure balance channel 186, which can be understood as that the convex wall 1821 is located on the side of the separation box cover 182 close to the air pressure balance channel 186, and / or the top cover 183 is located on the side of the separation box cover 182 close to the air pressure balance channel 186, that is, the condensation cavity 184 is located on the side away from the liquid storage member 200, at the same time, the inside of the separation box cover 182 located in the condensation cavity 184 is provided with a communication port 185, which communicates the condensation cavity 184 and the separation cavity 110, so that the water vapor in the humid air is condensed to form liquid drops in the condensation cavity 184, and then falls into the separation cavity 110 through the communication port 185, and the condensation cavity 184 is located on the side away from the liquid storage member 200, so that the communication port 185 is away from the liquid storage member 200, and the condensed liquid drops fall into the separation cavity 110 from the position away from the liquid storage member 200, thereby reducing the possibility of the liquid drops adhering to the surface of the liquid storage member 200, reducing the possibility of the liquid drops falling on the ground or on the user when the user extracts the liquid storage member 200, and improving the user's experience.

[0100] In some embodiments, as shown in FIG. 20, the convex wall 1821 includes a peripheral convex wall 1822 and an internal convex wall 1823, the peripheral convex wall 1822 and the top cover 183 surround to form the condensation cavity 184, and / or the peripheral convex wall 1822 and the separation box cover 182 surround to form the condensation cavity 184; the internal convex wall 1823 extends along a curve in the condensation cavity 184 to form a condensation channel 1842 in the condensation cavity 184, by making the internal convex wall 1823 extend along a curve to form a condensation channel 1842 extending along a curve, thereby increasing the surface area of the outer surface of the condensation channel 1842, enabling the condensation channel 1842 to be in more sufficient contact with the humid air entering the condensation cavity 184, thereby accelerating the condensation speed of the humid air; at the same time, the side wall of the peripheral convex wall 1822 and / or the internal convex wall 1823 adjacent to the condensation channel 1842 is convexly provided with heat exchange fins 1845, and a plurality of heat exchange fins 1845 are arranged in the extension direction of the condensation channel 1842, thereby further increasing the surface area of the outer surface of the condensation channel 1842, and further accelerating the condensation speed of the humid air.

[0101] In some embodiments, as shown in FIG. 20, the condensation channels 1842 have projections on the first plane different from the projection on the first plane of the air pressure balancing channel 186, the condensation channel 1842 with the smallest distance to the projection on the first plane of the air pressure balancing channel 186 is the first condensation channel 1846, i.e., the first condensation channel 1846 is the one closest to the air pressure balancing channel 186 among the condensation channels 1842, wherein the first plane is a plane with the thickness direction of the liquid distribution box cover 182 as the normal.

[0102] Meanwhile, the liquid distribution box cover 182 also has a water inlet pipe 188, the water inlet pipe 188 communicates with the first condensation channel 1846, the number of the communication openings 185 on the part of the liquid distribution box cover 182 located in the first condensation channel 1846 is greater than the number of the communication openings 185 on the part of the liquid distribution box cover 182 located in the second condensation channel 1847, the second condensation channel 1847 is a condensation channel 1842 other than the first condensation channel 1846 among the condensation channels 1842, it can be understood that the water inlet pipe 188 can guide water into the first condensation channel 1846 and flow into the liquid distribution cavity 110 through the communication openings 185 located in the first condensation channel 1846, so as to mix the detergent in the liquid distribution cavity 110 with water, i.e., the first condensation channel 1846 is not only used to realize the condensation function, but also used to realize the water inlet function, by arranging more communication openings 185 in the first condensation channel 1846, the water flowing in from the water inlet pipe 188 can flow into the liquid distribution cavity 110 from multiple different positions, so as to make the detergent mix with water more fully.

[0103] Optionally, as shown in FIG. 20, the heat exchange fins 1845 are arranged in the second condensation channel 1847 and are arranged at intervals along the extension of the second condensation channel 1847, so as to further improve the condensation capacity of the second condensation channel 1847, while not arranging the heat exchange fins 1845 in the first condensation channel 1846, so as to reduce the blocking effect of the heat exchange fins 1845 on the water flow flowing into the first condensation channel 1846 from the water inlet pipe 188, and reduce the flow resistance of the liquid flow in the first condensation channel 1846. Optionally, the projection of the second condensation channel 1847 on the bottom surface of the liquid distribution cavity 110 is located in the first liquid outlet 111, so that the liquid drops condensed in the second condensation channel 1847 directly drip out of the liquid distribution cavity 110 through the first liquid outlet 111 after dripping into the liquid distribution cavity 110, so as to further reduce the possibility of the condensed water dripping into the liquid distribution cavity 110 splashing and falling on the outer surface of the liquid storage member 200.

[0104] Optionally, as shown in FIG. 20, the liquid distribution box cover 182 further has a third liquid outlet 189, the third liquid outlet 189 is in communication with the first condensing channel 1846, and the third liquid outlet 189 can guide water to the sealing rubber bowl of the washing machine door. The water entering the first condensing channel 1846 through the water inlet pipe 188 can flow out of the third liquid outlet 189 and wash the foam attached to the sealing rubber bowl of the washing machine door.

[0105] In some embodiments, as shown in FIG. 21, the outer surface of the side and / or bottom of the liquid distribution box 100 has a pipe fixing member 193, and the pipe of the liquid delivery device 10 and the washing machine can be fixed to the outer surface of the liquid distribution box 100 through the pipe fixing member 193.

[0106] In some embodiments, as shown in FIG. 1, the outer surface of the liquid suction pipe 500 is provided with a temperature sensor (for example, a positive temperature coefficient thermistor), and the temperature of the area where the temperature sensor is located in the liquid suction pipe 500 can be obtained through the temperature sensor, so as to determine whether the fluid flowing in the liquid suction pipe 500 is liquid or air. It can be understood that the heat absorption capacity of the area where the temperature sensor is located when the liquid contacts the area is greater than the heat absorption capacity of the area when the air contacts the area, so if the temperature of the area where the temperature sensor is located is greater than a temperature threshold, it indicates that the fluid flowing in the liquid suction pipe 500 is liquid. If the fluid flowing in the liquid suction pipe 500 is liquid, it indicates that the remaining amount of detergent in the liquid storage cavity 210 is sufficient, and if the fluid flowing in the liquid suction pipe 500 is air, it indicates that the remaining amount of detergent in the liquid storage cavity 210 is insufficient.

[0107] In some embodiments, as shown in FIG. 1, the outer surface of the liquid suction pipe 500 is provided with a light transmittance sensor 902, and the size of the bubbles in the liquid suction pipe 500 can be obtained through the light transmittance sensor 902. It can be understood that in the state where the remaining amount of detergent in the liquid storage cavity 210 is insufficient, the suction pipe 700 will suck in a part of air while sucking in the detergent, and the less the remaining amount of detergent, the more air is sucked in, so that the bubbles in the liquid suction pipe 500 are larger or the number of bubbles is more. In the state where the size of the bubbles in the liquid suction pipe 500 obtained through the light transmittance sensor 902 is greater than a preset volume threshold, or the speed of the bubbles is greater than a preset speed threshold, the control alarm member outputs a low liquid prompt signal to prompt the user to supplement the detergent.
