[0047] It should be noted that in the description of this preferred embodiment, unless otherwise clearly specified and limited, the terms "connected" and "communicated" should be understood in a broad sense. For example, they can be directly connected, indirectly connected through an intermediate medium, or connected inside two components. These should not be understood as limitations to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] A washing capsule is a small and innovative laundry product. It contains a certain amount of detergent inside, which can avoid the situation where the amount of detergent manually poured by the user is too much or too little. At the same time, the washing capsule also has different laundry functions, such as bleaching, wrinkle removal, softening, etc. Different from laundry beads, the outer shell of the washing capsule is insoluble in water, which can avoid rupture due to humid air. In the prior art, when the washing capsule is placed in the dosing tray, the washing machine pierces the upper membrane body of the washing capsule and sucks out the detergent inside the washing capsule through a siphon. This method is likely to leave a large amount of detergent inside the washing capsule and cannot be fully utilized.

[0049] Therefore, the present invention provides a washing device to solve the above technical problems.

[0050] First, refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 are respectively a sectional view of the washing device provided by the present invention in the state where the washing program is not started and a sectional view in the state where the washing program is started. Combining Figure 1 and Figure 2, the present invention provides a washing device, which includes a dosing box 1 and a washing drum (not shown in the figure). A puncturing structure 11 that can move up and down is arranged inside the dosing box 1. The washing capsule 2 is fixed on the upper side of the puncturing structure 11. When the puncturing structure 11 moves upward, the puncturing structure 11 punctures the bottom of the washing capsule 2, and the dosing box 1 communicates with the washing drum to discharge the detergent in the washing capsule 2 into the washing drum. Based on the above structural arrangement, when the washing program of the washing device provided by the present invention is not started, as Figure 1 shown, due to gravity, the puncturing structure 11 sinks to the bottom of the dosing box 1. When the washing program is started, as Figure 2 shown, the washing capsule 2 is punctured by the upward movement of the puncturing structure 11, so that the detergent inside it flows out from the bottom of the washing capsule 2. Furthermore, there is no need to provide a siphon, avoiding detergent residue. It should be noted that the present invention does not impose any restrictions on the specific materials and set dimensions of the dosing box 1 and the washing capsule 2, and only needs to meet the structural adaptation of the dosing box 1 and the washing capsule 2. Those skilled in the art can set them according to actual usage requirements.

[0051] In addition, the present invention does not impose any restrictions on the number and specific length of the puncturing structure 11. Those skilled in the art can set them according to actual usage requirements. For example, the number of the puncturing structures 11 can be one, and this puncturing structure 11 is directly opposite to the center of the bottom of the washing capsule 2. Or, the number of the puncturing structures 11 can be multiple, and multiple puncturing structures 11 are arranged at intervals on the bottom of the washing capsule 2. It can be understood that the more the number of the puncturing structures 11, the better the puncturing effect on the washing capsule 2. And, the length of the puncturing structure 11 should not be too long, and only needs to meet the requirement of being able to penetrate the bottom surface of the washing capsule 2.

[0052] In this preferred embodiment, the number of the dosing boxes 1 is multiple to place different types of washing capsules, avoiding the mixing and reaction of the detergents in different types of washing capsules. It should be noted that the present invention does not impose any restrictions on the specific number of the dosing boxes 1. Those skilled in the art can set it according to actual usage requirements. For example, the number of the dosing boxes 1 can be two, three, four, etc. As Figure 1 shown, it is preferred that the number of the dosing boxes 1 is two. Among them, the upper dosing box 1 is provided with the washing capsule 2, and the lower dosing box 1 is not provided with the washing capsule 2.

[0053] Therefore, when the user needs to wash clothes, the user can directly place the washing capsule 2 containing the detergent inside the washing device for washing clothes. Here, the washing capsule 2 can be directly placed in the dosing box 1 of the washing device for use. Once the detergent in the dosing box 1 is used up, it can be placed as needed, which is convenient to operate and enables healthy washing. Among them, the washing capsule 2 can be divided into the detergent used in the washing process and the detergent used in the rinsing process, with multiple types in two categories. For example, the detergent can be a disinfectant, a renovator, etc. used in the main washing process, and the detergent can also be a fragrance, a conditioner, etc. used in the rinsing process. In a possible implementation manner, a detergent dosing port is provided in the dosing box 1, and the detergent dosing port is connected to a switching valve, which can be a reversing valve, a one-way valve, etc. When the switching valve is opened, the detergent in the dosing box 1 can be put into the washing tub to wash clothes. When the switching valve is closed, the injection of the detergent stops. Thus, the dosing of the detergent can be controlled by the switching valve, and the automatic on-demand dosing of the detergent can be achieved.

[0054] In this preferred embodiment, the washing device provided by the present invention further includes a waterway assembly 3. The dosing box 1 is arranged below the waterway assembly 3 and is communicated with the waterway assembly 3. When the waterway assembly 3 is not injecting water, the puncturing structure 11 sinks to the bottom of the dosing box 1 due to gravity. When the waterway assembly 3 injects water into the dosing box 1, the puncturing structure 11 moves upward under the action of buoyancy, and then can puncture the washing capsule 2 to let out the washing liquid. After the waterway assembly 3 stops injecting water into the dosing box 1, the puncturing structure 11 drops with the water level and finally returns to its original position. This structure enables the washing capsule 2 to be punctured only after the waterway startup program of the washing device, which can avoid the waste of detergent caused by the user misplacing the capsule.

[0055] In this preferred embodiment, the puncturing structure 11 includes a moving part 111 and a tip 112. The moving part 111 moves up or down in the dosing box 1 according to the water level height. The tip 112 is located on the upper side of the moving part 111 and is used to puncture the washing capsule 2. Among them, the moving part 111 is used to drive the tip 112 to move up and down, and the tip 112 is used to puncture the washing capsule 2. When the washing program is started, water flows through the waterway assembly 3. The moving part 111 floats on the water level according to the buoyancy. As the water level continuously rises, the moving part 111 continuously moves up, and then drives the tip 112 to move up to puncture the washing capsule 2, so that the detergent flows out. In addition, in this preferred embodiment, the puncturing structure 11 is arranged perpendicular to the bottom surface of the washing capsule 2, which can enhance the piercing effect of the puncturing structure 11 and further promote the outflow of the detergent.

[0056] It should be noted that the present invention does not impose any restrictions on the connection manner between the moving part 111 and the tip 112, and those skilled in the art can set it according to actual usage requirements. For example, the moving part 111 and the tip 112 can be integrally formed, or can be assembled after being processed separately. Preferably, the moving part 111 and the tip 112 are integrally formed to have a strong connection strength between the moving part 111 and the tip 112, and to prevent them from detaching under the action of external force.

[0057] It should be noted that the present invention does not impose any restrictions on the structures of the moving part 111 and the tip 112, and those skilled in the art can set them according to actual usage requirements. For example, the moving part 111 can be a cuboid, a cylinder, etc., and the tip 112 can be a quadrangular pyramid and a cone.

[0058] In this preferred embodiment, the moving part 111 is hermetically arranged and hollow inside, so that the buoyancy of the moving part 111 is relatively large, facilitating the up-and-down movement of the moving part 111 according to the water level in the dosing box 1. It should be noted that the present invention does not impose any restrictions on the hollow volume inside the moving part 111, and those skilled in the art can set it according to actual usage requirements. It can be understood that the larger the hollow volume inside the moving part 111, the greater the buoyancy of the moving part 111, and the easier it is for the tip 112 to pierce the washing capsule 2.

[0059] In this preferred embodiment, refer to Figure 3 , Figure 3 is a schematic structural view of the limiting member in the washing device provided by the present invention. As Figure 3 shown, a limiting member 12 is further arranged inside the dosing box 1. The limiting member 12 is vertically arranged inside the dosing box 1, so that the moving part 111 is arranged inside the limiting member 12 in a vertically movable manner. Among them, the vertical arrangement of the limiting member 12 can limit the movement track of the moving part 111, so that it can only move up and down in the limiting member 12, preventing it from moving horizontally or rotating, and further preventing the tip 112 from deviating from the piercing area. It should be noted that the present invention does not impose any restrictions on the structure of the limiting member 12, and those skilled in the art can set it according to actual usage requirements.

[0060] In this preferred embodiment, the limiting member 12 includes a first limiting portion 121 and a second limiting portion 122. The first limiting portion 121 is disposed perpendicular to the bottom surface of the dispensing cartridge 1, and the first limiting portion 121 is provided with a communication groove 1211. The moving portion 111 passes through the communication groove 1211 and is movably disposed up and down within the first limiting portion 121. The second limiting portion 122 is disposed at the top of the first limiting portion 121, and the interior of the second limiting portion 122 is hollow. The tip 112 can pass through the hollow of the second limiting portion 122. Among them, the first limiting portion 121 is used to limit the movement trajectory of the moving portion 111 so that it can only move up and down within the communication groove 1211. The second limiting portion 122 is used to limit the movement trajectory of the tip 112. When the moving portion 111 rises to a certain height, a part of the tip 112 passes through the second limiting portion 122 for puncturing the washing capsule 2, and another part of the tip 112 abuts against the lower end of the second limiting portion 122 to prevent the tip 112 from continuously moving up and puncturing other components within the dispensing cartridge 1.

[0061] It should be noted that the present invention does not impose any restrictions on the structures and set dimensions of the first limiting portion 121 and the second limiting portion 122, and those skilled in the art can set them according to actual usage requirements. For example, Figure 3 as shown, the first limiting portion 121 can be a cylinder, and the second limiting portion 122 can be a ring.

[0062] In this preferred embodiment, the first limiting portion 121 is further provided with weight-reducing grooves 1222. The number of the weight-reducing grooves 1222 is two, and they are symmetrically disposed on both sides of the moving portion 111 for reducing the weight of the first limiting portion.

[0063] In this preferred embodiment, a liquid outlet is provided at the bottom of the dispensing cartridge 1. The liquid outlet is communicated with the washing tub. When the puncturing structure 11 punctures the washing capsule 2, the detergent in the washing capsule flows out through the liquid outlet into the washing tub. Specifically, water flows through the waterway assembly 3, and the moving portion 111 floats on the water level according to buoyancy. As the water level continuously rises, the moving portion 111 continuously moves up, thereby driving the tip 112 to move up to puncture the washing capsule 2, so that the detergent flows out into the liquid outlet and then into the washing tub to wash the clothes.

[0064] In this preferred embodiment, refer to Figure 4 , Figure 4 which is a schematic structural view of the washing capsule provided by the present invention. As Figure 4As shown, the inside of the washing capsule 2 is filled with detergent, and the bottom is sealed by a membrane body 21, so that the puncturing structure 11 can puncture the washing capsule 2 through the membrane body 21. Therefore, users can directly purchase the corresponding washing capsule 2. When they need to wash clothes, they can directly place the washing capsule 2 filled with detergent inside the washing equipment for washing clothes. Here, the washing capsule 2 purchased by the user can be directly placed in the dosing box 1 of the washing equipment for use. Once the detergent in the dosing box 1 is used up, it can be placed as needed, which is convenient to operate and enables healthy washing. Among them, the washing capsules can be divided into detergents used in the washing process and detergents used in the rinsing process, with multiple types in two categories. For example, the detergent can be a disinfectant, a renovator, etc. used in the main washing process, or it can be a fragrance, a care agent, etc. used in the rinsing process.

[0065] In this preferred embodiment, the bottom of the washing capsule 2 includes an inclined surface 22 and a bottom surface 23 that are connected in sequence, so that the detergent inside the washing capsule 2 flows from the inclined surface 22 to the bottom surface 23, facilitating the outflow of the internal detergent and avoiding residue. In addition, the bottom surface 23 is sealed by a membrane body 21, which is convenient to be punctured by the puncturing structure 11 to allow the detergent to flow out. It should be noted that the present invention does not impose any restrictions on the specific structure and set dimensions of the inclined surface 22 and the bottom surface 23, and those skilled in the art can set them according to actual usage requirements. It can be understood that on the premise that the bottom size of the washing capsule 2 is fixed, the smaller the area of the bottom surface 23, the larger the area of the inclined surface 22, and the better the flowability of the detergent. On the contrary, the larger the area of the bottom surface 23, the smaller the area of the inclined surface 22, and the worse the flowability of the detergent. Therefore, the area of the bottom surface 23 does not need to be too large, and it only needs to ensure that it can be penetrated by the puncturing structure 11. In addition, the larger the inclination angle of the inclined surface 22, the faster the flow rate of the detergent, but the smaller the accommodating space of the washing capsule 2; on the contrary, the smaller the inclination angle of the inclined surface 22, the slower the flow rate of the detergent, but the larger the accommodating space of the washing capsule 2. Those skilled in the art can set it according to actual usage requirements.

[0066] In this preferred embodiment, refer to Figure 4, a through hole 231 is provided on the bottom surface 23 of the washing capsule 2, and the first film body 21 seals the through hole 231 by plastic encapsulation. The tip 112 pierces through the through hole 231 to puncture the first film body 21. During the production process of the washing capsule 2, it is necessary to pour detergent into the empty washing capsule 2 and then seal it by pressing the film. However, the washing capsule 2 filled with detergent is prone to overflow during the film pressing process. To solve the above problems, the present invention defines that the bottom surface 23 of the washing capsule 2 is provided with a through hole 231. During the production process of the washing capsule 2, the factory can pour detergent into it through the through hole 231 of the washing capsule 2 and then seal it by the first film body 21. Since the size of the through hole 231 is small, this method can alleviate the overflow phenomenon of the detergent. It should be noted that the present invention does not impose any restrictions on the specific structure and size of the through hole 231, and only needs to satisfy that the tip 112 can pass through the through hole 231. Those skilled in the art can set it according to actual usage requirements. For example, the through hole 231 can be a circular hole or a square hole.

[0067] It should be noted that the above embodiments are only used to illustrate the principle of the present invention and are not intended to limit the protection scope of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0068] So far, the technical solutions of the present invention have been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
