[0041] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art can adjust them as needed to adapt to specific application scenarios. For example, although this specific implementation manner is described in the context of applying a protection device to a washing device, it is obvious that the control method of the washing device of the present invention can also be used in other devices. Such changes in the application scenario do not deviate from the basic principle of the present invention and belong to the protection scope of the present invention.

[0042] The washing capsule is a small and innovative laundry product with a certain amount of detergent inside, which can avoid the situation that the 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. In the prior art, when the washing capsule is placed in the dosing chute, the washing machine pierces the upper membrane body of the washing capsule and sucks out the detergent inside the washing capsule through a siphon member. This method requires a needle for piercing the washing capsule to be pre-set. The needle is usually arranged inside the lid and pierces the washing capsule as the lid is opened and closed. However, the prior art has certain safety hazards in the setting method of the needle. When the user operates improperly, it is easy to cause scratches, and the user experience is poor.

[0043] Correspondingly, there is a need in the art for a washing device to solve the problem in the prior art that the setting method of the needle has certain safety hazards, and it is easy to cause scratches when the user operates improperly, and the user experience is poor. Therefore, the present invention provides a washing device aiming to solve the above technical problems.

[0044] First, refer to Figure 1 and Figure 2 , wherein,Figure 1 is a schematic diagram of the overall structure of the washing device provided by the present invention, Figure 2 is a schematic diagram of the dosing slot structure when the cover body of the washing device provided by the present invention is in the open state. Combining Figure 1 and Figure 2 , the washing device provided by the present invention is provided with a dosing slot 1, a connecting mechanism 2, and a washing tub (not shown in the figure). A washing capsule (not shown in the figure) is arranged inside the dosing slot 1, and the dosing slot 1 communicates with the washing tub to deliver the detergent in the washing capsule into the washing tub. A cover body 11 is arranged on the upper side of the dosing slot 1, and the connecting mechanism 2 is connected to the cover body 11. The connecting mechanism 2 includes a puncture needle 21, and the tip 211 of the puncture needle 21 can extend or retract into the connecting mechanism 2. Based on the above structural arrangement, when the cover body 11 is opened, the tip 211 of the puncture needle 21 retracts into the connecting mechanism 2 to prevent scratching the user; when the cover body 11 is closed, the tip 211 of the puncture needle 21 extends out of the connecting mechanism 2 to puncture the washing capsule, so that the detergent inside it flows out into the washing tub. It should be noted that the present invention does not impose any restrictions on the specific structures of the dosing slot 1, the cover body 11, the connecting mechanism 2, and the puncture needle 21, and those skilled in the art can set them according to actual usage requirements.

[0001] In this preferred embodiment, the tip 211 is used to puncture the film body at the top of the washing capsule to enhance the outflow of the detergent. When the user buckles the cover body 11 on the upper part of the dosing slot 1, the puncture needle 21 extends out of the connecting mechanism 2 to puncture the washing capsule, so that the detergent flows out. It should be noted that the present invention does not impose any restrictions on the specific material and set size of the tip, and only needs to satisfy that the tip 211 can puncture the film body. Those skilled in the art can set them according to actual usage requirements.

[0002] In this preferred embodiment, continue to refer to Figure 1 , the cover body 11 of the washing device provided by the present invention is hollow inside and is reversibly buckled on the upper side of the dosing slot 1. When the user uses the washing capsule to wash clothes, at this time the dosing slot 1 is used to accommodate the washing capsule, and the cover body 11 is used to fix the washing capsule inside the dosing slot 1. In this embodiment, the user can flip the cover body 11 open, then put the washing capsule into the dosing slot 1, and then buckle the cover body 11 on the upper side of the dosing slot 1 to perform the washing program; in another possible embodiment, when the washing capsule is used up, the user directly uses the detergent to wash clothes. At this time, the user does not need to open the cover body 11, and only needs to pour the detergent into the inside of the dosing slot 1 through the hollow part inside the cover body 11 to perform the washing program. It should be noted that the present invention does not impose any restrictions on the specific structure and size of the cover body 11, and those skilled in the art can set them according to actual usage requirements.

[0003] In this preferred embodiment, refer to Figure 2, in the washing device provided by the present invention, the connecting mechanism 2 is provided with a sliding groove 22, and the tip 211 is disposed in the sliding groove 22 in a retractable manner. Among them, the sliding groove 22 is used to define the telescopic path of the tip 211 to prevent the puncture needle 21 from bending when extending or retracting, thereby causing damage. It should be noted that the present invention does not impose any restrictions on the specific structure and installation position of the sliding groove 22, and those skilled in the art can set it according to actual usage requirements. It can be understood that when the cover 11 is not buckled, the bottom of the sliding groove 22 is flush with the tip 211 of the puncture needle 21 to ensure that the puncture needle 21 is completely covered by the connecting mechanism 2 and prevent the tip 211 from being exposed. Optionally, the structure of the sliding groove 22 can be the same as that of the puncture needle 21, so that the sliding groove 22 fits the structure of the puncture needle 21. For example, both the sliding groove 22 and the puncture needle 21 are cylindrical. It can be understood that in order to make the puncture needle 21 slide smoothly during extension or retraction, the diameter of the sliding groove 22 can be slightly larger than the outer diameter of the cross-section of the puncture needle 21.

[0004] For the telescopic structure of the tip 211, the washing device provided by the present application provides two possible implementation manners.

[0005] In a possible implementation manner, refer to Figure 3 , Figure 3 is a sectional view of the first implementation manner of the washing device provided by the present invention. As Figure 3 shown, the connecting mechanism 2 is disposed at the bottom of the cover 11, and the root end 212 of the puncture needle 21 is fixed to the bottom of the cover 11. It should be noted that the present invention does not impose any restrictions on the connection manner between the root end 212 and the cover 11, and those skilled in the art can set it according to actual usage requirements. Optionally, the root end 212 and the cover 11 can be integrally formed. It can be understood that when the root end 212 of the puncture needle 21 is fixed to the bottom of the cover 11, the puncture needle 21 and the cover 11 maintain a relative position unchanged. Only by the relative movement of the connecting mechanism 2 and the cover 11 can the relative movement of the sliding groove 22 and the puncture needle 21 be realized, that is, the extension or retraction of the tip 211 is realized by the relative movement of the connecting mechanism 2 and the cover 11.

[0006] In this preferred embodiment, there is a gap between the top of the connecting mechanism 2 and the cover 11. Therefore, the relative movement of the connecting mechanism 2 and the cover 11 is realized through the gap between the top of the connecting mechanism 2 and the cover 11, and further the extension or retraction of the tip 211 is realized. It can be understood that the height of the gap between the top of the connecting mechanism 2 and the cover 11 is the extendable length of the tip 211, and those skilled in the art can set the height of the gap between the top of the connecting mechanism 2 and the cover 11 according to actual usage requirements.

[0007] In this embodiment, a limiting member 23 is provided at the bottom of the connecting mechanism 2. When the connecting mechanism 2 falls with the cover body 11, the limiting member 23 pushes the connecting mechanism 2 to move upward, so that the tip 211 of the needle 21 is exposed for piercing the washing capsule. Therefore, in this embodiment, the user does not need to manually control the needle 21 to pierce the washing capsule. By simply buckling the cover body 11 on the upper side of the feeding slot 1, the limiting member 23 can only be used to push the connecting mechanism 2 to move, and then the exposed tip 211 is used to pierce the washing capsule. It should be noted that the present invention does not impose any restrictions on the specific structure and installation position of the limiting member 23, and those skilled in the art can set it according to actual usage requirements. In this preferred embodiment, the height of the limiting member 23 is greater than a preset value and less than or equal to the height of the gap. It can be understood that the height of the limiting member 23 is the moving distance of the connecting mechanism 2 and also the exposed length of the tip 211. Optionally, when the exposed length of the tip 211 is too short, the needle 21 cannot completely pierce the washing capsule. Therefore, it is necessary to set the height of the limiting member 23 to be greater than the preset value. In this process, those skilled in the art can set the preset value according to actual usage requirements. At the same time, when the height of the limiting member 23 is too large, the moving distance of the connecting mechanism 2 is also too large, and the remaining gap length is insufficient, which easily causes the structure to break. Therefore, it is also necessary to set the height of the limiting member 23 to be less than or equal to the height of the gap.

[0008] Optionally, the number of the limiting members 23 is two, which are symmetrically arranged on both sides of the bottom of the connecting mechanism 2, so that when the connecting mechanism 2 is pushed, it moves upward symmetrically on both sides, improving the balance of the connecting mechanism and preventing it from tilting during the movement. In addition, the limitation on the number of the limiting members 23 in the present invention is not fixed, and those skilled in the art can adjust it according to needs. For example, the number of the limiting members 23 can also be four, six or other numbers. It can be understood that in order to ensure the balance and stability of the connecting mechanism, the limiting members 23 are evenly arranged on both sides of the connecting mechanism 2.

[0009] In this preferred embodiment, the connecting mechanism 2 and the cover body 11 are connected by screws 24, and a first elastic member 241 is sleeved outside the screws 24. By providing the first elastic member 241, when the cover body 11 is opened again, the first elastic member 241 drives the connecting mechanism 2 to rebound, so that the lancet 21 is wrapped in the connecting mechanism 2 again, thereby avoiding scratching the user. Therefore, in this embodiment, the user does not need to manually control the reset of the lancet 21. Only by opening the cover body 11, the first elastic member 241 can rebound, and then push the connecting mechanism 2 to reset and move, so that the lancet 21 is wrapped by the connecting mechanism 2 again. It should be noted that the present invention does not limit the specific structure of the first elastic member 241, and those skilled in the art can set it according to actual usage requirements. Optionally, the first elastic member 241 can be a spring. At the same time, the present invention does not limit the number of the first elastic members 241, and those skilled in the art can set it according to actual usage requirements. For example, when the number of the screws 24 is two, the two screws 24 are symmetrically arranged on the upper side of the connecting mechanism 2. At this time, those skilled in the art can choose to sleeve a spring outside one of the screws 24, or choose to sleeve springs outside both of the screws 24 at the same time.

[0010] In another possible embodiment, refer to Figure 4 , Figure 4 is a sectional view of the second embodiment of the washing device provided by the present invention. As Figure 4 shown, the connecting mechanism 2 is arranged inside the cover body 11, the top of the connecting mechanism 2 protrudes from the cover body 11, and the root end 212 of the lancet 21 is fixed to the top of the connecting mechanism 2. It should be noted that the present invention does not limit the connection manner between the root end 212 and the connecting mechanism 2, and those skilled in the art can set it according to actual usage requirements. Optionally, the root end 212 and the connecting mechanism 2 can be integrally formed. It can be understood that when the root end 212 of the lancet 21 is fixed to the top of the connecting mechanism 2, the lancet 21 and the connecting mechanism 2 maintain their initial relative positions unchanged. Only by pressing the connecting mechanism 2, the connecting mechanism 2 can be elastically deformed, so as to realize the extension or retraction of the tip 211. Therefore, the user can press the protruding part of the connecting mechanism 2 to move the lancet 21 downward, thereby realizing the extension or retraction of the tip 211.

[0011] In this embodiment, a second elastic member 213 is sleeved outside the lancet 21. After the lancet 21 pierces the washing capsule, the second elastic member 213 drives the lancet 21 to rebound, so that the lancet 21 is wrapped in the connecting mechanism 2 again, thereby avoiding scratching the user. Therefore, in this embodiment, the user does not need to manually control the reset of the lancet 21. By only stopping pressing the protruding part of the connecting mechanism 2, the second elastic member 213 can rebound, and then the connecting mechanism 2 moves back to its original position, so that the lancet 21 is covered by the connecting mechanism 2 again. It should be noted that there is no limitation on the specific structure of the second elastic member 213 of the present invention, and those skilled in the art can set it according to actual usage requirements. Optionally, the second elastic member 213 can be a spring.

[0012] In this preferred embodiment, the number of lancets 21 is multiple, and they are arranged at intervals in the connecting mechanism 2, so that the washing capsule can be pierced by multiple lancets 21 at the same time, increasing the flow rate of the detergent in the washing capsule, and thus improving the washing effect. It can be understood that the more the number of lancets 21 is set, the better the piercing effect on the washing capsule. And the length of the lancet 21 should not be too long, and only needs to be able to penetrate the surface film of the washing capsule. Optionally, as Figure 4 shown, the number of lancets 21 can be two, and they are symmetrically arranged inside the connecting mechanism 2. Based on the number of lancets 21 being two, the present invention does not limit the number of the second elastic members 213, and those skilled in the art can set it according to actual usage requirements. For example, those skilled in the art can choose to sleeve a spring outside one of the lancets 21, or choose to sleeve springs outside both lancets 21 at the same time.

[0013] In this preferred embodiment, the number of the dosing slots 1 is multiple, for placing different types of washing capsules to prevent the detergents in different types of washing capsules from mixing and reacting with each other. It should be noted that the present invention does not limit the specific number of the dosing slots 1, and those skilled in the art can set it according to actual usage requirements. For example, the number of the dosing slots 1 can be two, three, four, etc. As Figure 1 shown, it is preferred that the number of the dosing slots 1 is two. Among them, a cover body 11 is provided in the upper dosing slot 1, and no cover body 11 is provided in the lower dosing slot 1.

[0014] Therefore, when a user needs to wash clothes, the user can directly place the washing capsule containing detergent inside the washing device for washing clothes. Here, the washing capsule can be directly placed into the dosing tank 1 of the washing device for use. Once the detergent in the dosing tank 1 is used up, it can be placed as needed, which is convenient to operate and enables healthy washing. Among them, the washing capsule 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 conditioner, etc. used in the rinsing process. In a possible implementation manner, a detergent dosing port is provided in the dosing tank 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 tank 1 can be put into the washing drum to wash clothes. When the switching valve is closed, the injection of detergent stops. Thus, the dosing of detergent can be controlled by the switching valve, and automatic on-demand dosing of detergent can be achieved.

[0015] In this preferred embodiment, a liquid outlet (not shown in the figure) is provided at the bottom of the dosing tank 1, and the liquid outlet is communicated with the washing drum. When the needle 21 pierces the washing capsule, the detergent in the dosing tank 1 flows out through the liquid outlet into the washing drum.

[0016] In summary, for the washing device provided by the present invention, when the cover 11 is opened, the tip 211 of the needle 21 retracts into the connecting mechanism 2 to prevent scratching the user; when the cover 11 is closed, the tip 211 of the needle 21 extends out of the connecting mechanism 2 to pierce the washing capsule, so that the detergent inside it flows out into the washing drum.

[0017] 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.

[0018] So far, the technical solutions of the present invention have been described in conjunction 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.
