[0051] It should be understood that the term "and / or" used herein is only a description of the associated relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0052] It should also be noted that the terms "comprising", "including", or any other variants thereof are intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such a commodity or system. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the said element.

[0053] The present invention provides a detergent dispensing assembly, as Figure 4 , Figure 11 , Figure 12 , Figure 13 shown, which includes a detergent box 1 and a mounting box body 2. A cavity for mounting the detergent box 1 is formed in the mounting box body 2, and the detergent box 1 is detachably connected or movably connected within the mounting box body 2.

[0054] As Figure 5 , Figure 6 , Figure 7 , Figure 8 shown, it further includes a pressing mechanism, which is provided on the mounting box body or the detergent box and is used to provide a pressing force to the top of the detergent box to make the detergent box more stable when fixed or moving within the mounting box body.

[0055] Preferably, a pressing mechanism is provided on the top of the installation box 2 to position and press the detergent box 1 during installation or removal. Figure 6 , Figure 7 , Figure 8 As shown, the clamping mechanism includes a mounting seat 211, a spring 214 and a clamping portion. The mounting seat 211 is constructed as a hollow shell structure, and a mounting space is formed inside it, preferably an mounting space with one end open and the other end closed; the clamping portion is slidably arranged in the mounting space, and a part of the clamping portion can extend into the cavity of the mounting box to provide pressure to the detergent box; the spring 214 is arranged in the mounting space, abuts against the clamping portion, provides elastic force to the clamping portion, and moves the clamping portion out of the mounting space.

[0056] Preferably, the mounting seat 211 is constructed as a barrel-shaped structure with one end open and the other end closed, and a limiting groove or a limiting hole is provided on its side wall along its axial direction for limiting the clamping part. Furthermore, the limiting hole extends along the axial direction of the mounting seat 211 to form a long hole, which can also guide the movement of the clamping part.

[0057] Preferably, the clamping portion includes a limiting claw, which is slidably engaged in the limiting groove or the limiting hole and can slide in the limiting hole, so that the clamping portion can slide along the axial direction of the mounting seat 211.

[0058] In this embodiment, the pressing part includes a pressing wheel 213 and a pressing wheel bracket 212. A limit claw is provided on the pressing wheel bracket 212, and the pressing wheel bracket 212 is slidably connected to the mounting seat 211 through the limit claw. The pressing wheel 213 is rotatably provided on the pressing wheel bracket 212, and the pressing wheel 213 is used to abut against the detergent box. When the detergent box is installed in the installation box, the pressing mechanism presses the detergent box to prevent it from shaking.

[0059] Preferably, a limiting groove 106 is provided on the detergent box 1. When the detergent box 1 is located at a preset position, the pressing part rolls into the limiting groove 106, which can provide a certain resistance to the sliding of the detergent box 1. When the detergent box 1 is installed in place, the limiting groove 106 is staggered with the pressing part, and the limiting groove 106 is located near the inner side. In this way, when the detergent box 1 is ejected, the pressing part enters the limiting groove 106 after sliding outward for a certain distance, which can prevent the detergent box 1 from continuing to slide outward, thereby preventing the detergent box 1 from sliding out by itself and falling. When the detergent box 1 is pulled hard again, the pressing part extrusion spring 214 contracts, the pressing part rolls out of the limiting groove 106, and the detergent box 1 can continue to slide.

[0060] Preferably, a plurality of pressing mechanisms 21 are provided. The plurality of pressing mechanisms 21 are distributed along the moving direction of the detergent box 1, and / or the plurality of pressing mechanisms 21 are distributed on opposite sides of the detergent box, and it is sufficient to provide a pressing force to the detergent box 1.

A sealing cover is provided on the liquid injection port 101, and a valve is provided at the liquid outlet 102. The valve is used to block the liquid outlet 102 when the detergent box 1 is in a non-installed state;

[0063] A first liquid level detection device 19 is provided on the box body 10. The first liquid level detection device 19 is arranged at a position close to the liquid outlet 102 and is used to detect the liquid level in the box body 10;

[0064] It further includes an electrical connection part 14 provided on the outer wall of the box body 10. The electrical connection part 14 is electrically connected to the first liquid level detection device 19. When the box body 10 is in an installed state, the electrical connection part 14 is used to abut against an external device to form a detection circuit. Preferably, the electrical connection part 14 is electrically connected in a contact conduction manner. For example, it is configured as an elastic conductive sheet or a conductive column structure.

[0065] An accommodation cavity is formed inside the box body 10 for accommodating detergent. In this embodiment, the box body 10 is configured as a narrow and long structure. A liquid injection port 101 is formed above its side wall. An openable plugging cover 11 is provided at the liquid injection port 101. A plugging sealing ring 12 is provided on the plugging cover 11. The plugging cover 11 is preferably connected to the liquid injection port 101 by a rotary snap connection method to block the liquid injection port 101, or to open the liquid injection port 101 to inject detergent into the box body 10. In this embodiment, the liquid injection port 101 is formed on the side wall (i.e., the surface with the largest area). When adding detergent to the box body 10, the box body 10 will not tip over. It is also possible to set the opening of the liquid injection port 101 larger, so that it is more convenient to fill the detergent.

[0066] Preferably, the liquid outlet 102 is provided on the rear side panel of the cartridge 10, at the bottom of the rear side panel. The first liquid level detection device 19 is located above the liquid outlet 102 or at a position flush with the liquid outlet 102 for detecting the liquid level. In the present application, the rear side panel of the cartridge 10 is the innermost panel in the installed state. A flow guide plate is provided on the lower side inside the cartridge 10. The flow guide plate inclines towards the position where the liquid outlet 102 is located to form a flow guide surface, enabling the detergent to flow towards the liquid outlet 102 by itself. The first liquid level detection device 19 is preferably a liquid level probe. A first mounting hole is provided on the rear side plate of the cartridge 10. The first liquid level detection device 19 is installed in the first mounting hole, partially extending into the cartridge 10 and blocking the first mounting hole.

[0067] Preferably, a plurality of independent accommodating chambers are formed in the cartridge 10. Each accommodating chamber is correspondingly provided with a liquid injection port 101, an outlet, and a first liquid level detection device 19. Two accommodating chambers can be used to store different types of detergents, such as one for storing washing liquid and the other for storing fabric softener.

[0068] A one-way air inlet is further provided on the cartridge 10. When the air pressure in the cartridge 10 is low, air can flow into the cartridge 10. The air inlet is preferably provided on the side wall of the cartridge 10, for example, opposite to the liquid injection port 101. As Figure 3 shown, the one-way air inlet includes a through hole communicating with the inner cavity of the cartridge 10 and a one-way ventilation structure 13. The one-way ventilation structure 13 is snap-fitted at the communication hole and includes a blocking portion formed inside the cartridge 10. The blocking portion is made of a flexible material. When the air pressures inside and outside the cartridge 10 are the same, the blocking portion blocks the communication hole. When the air pressure in the cartridge 10 decreases due to the reduction of the detergent, under the action of the external air pressure, the blocking portion can deform to allow air to enter the cartridge 10. Preferably, in other embodiments, the one-way ventilation structure 13 can also be replaced by other forms of one-way valve structures.

[0069] Preferably, a rear cover 15 is further included. The rear cover 15 is snapped onto the rear side panel of the cartridge 10. An outlet corresponding to the liquid outlet 102 is provided on the rear cover 15. A valve is provided on the rear cover 15 and connected to the outlet.

A sealing ring is provided on the valve body 162. In the natural state, the needle valve spring presses the valve body 162 against the valve port of the valve body 162, and the valve port is sealed by the sealing ring to prevent the detergent in the box body 10 from flowing out. When the valve body 162 is pushed inward, the needle valve spring is compressed, the valve body 162 moves away from the valve port, the side portion of the valve body 162 is a hollow structure, and the valve port communicates with the inner cavity of the box body 10 through the hollow structure, enabling the detergent to flow out.

[0071] Preferably, the rear cover 15 is further provided with positioning holes 152 for the installation and positioning of the detergent box 1. Further, a plurality of positioning holes 152 are provided, and two positioning holes 152 are provided in this embodiment to improve the positioning accuracy.

[0072] The electrical connection part 14 is arranged between the rear side plate and the rear cover 15, and the electrical connection part 14 is electrically connected to the first liquid level detection device 19 through a wire. Arranging the electrical connection part 14 between the rear side plate and the rear cover 15 enables it to be separated from the interior of the box body 10 and not be completely exposed under the action of the rear cover 15, providing a certain degree of protection for it. An electrical connection hole 151 is formed on the rear cover 15 to expose at least part of the electrical connection part 14. The electrical connection hole 151 is a through hole formed on the rear cover 15, enabling the electrical connection structure to contact the electrical connection contact piece 14 through the electrical connection hole 151.

[0073] A magnet 17 is arranged between the rear cover 15 and the rear side plate. The magnet 17 is used to cooperate with the detection component for the installation position of the detergent box for installation detection. For example, it cooperates with a Hall sensor to detect whether the detergent box 1 is installed in place.

[0074] Preferably, a handle 104 is provided at the front end of the box body 10 for the operator to grasp. The handle 104 can be formed by an inward concave structure near the front end of the box body 10, or configured as a through hole penetrating the box body 10. Preferably, the handle 104 should not be set too large to reduce the space occupied in the inner cavity of the box body 10. Further, a decorative plate 105 is further provided at the front end of the box body 10 to make the box body 10 more beautiful after installation.

[0075] As Figure 5 shown, the installation box body 2 preferably includes a first shell 201 and a second shell 202. The first shell 201 and the second shell 202 form a shell structure with one end open, and the detergent box 1 is loaded into the shell structure, and the shell can protect it.
