Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more specifically, to a cleaner. Background Technology

[0002] The applicant's earlier application CN220876629U discloses a portable electric cleaning machine, including a housing. The housing is equipped with a water outlet pipe, a pump body, a water tank, a circuit board, and a power supply component. One end of the water outlet pipe is connected to a nozzle, and the other end is connected to the output end of the pump body. The power supply component and the pump body are electrically connected to the circuit board. The water tank is detachably fitted onto the outside of the housing, and one end of the housing is equipped with a connector. The water tank can be detached and assembled onto the connector. The connector is equipped with a water inlet and an air inlet. The input end of the pump body is connected to the water tank through the water inlet. The air inlet is equipped with a one-way valve to prevent water in the water tank from flowing out of the air inlet. By fitting the water tank onto the outside, it can be removed and assembled when needed, which increases the water storage capacity of the water tank without affecting the internal installation, and its structural layout is more reasonable.

[0003] The cleaning machine with the above structure uses a water tank that can be detachably fitted onto the outside of the casing to facilitate carrying. However, in actual use, the casing and water tank need to be carried separately. Furthermore, the water tank needs to be filled with water before use, and the two need to be assembled. After use, the water tank needs to be disassembled. Therefore, it is still not very convenient to carry and the disassembly and assembly is quite troublesome. Utility Model Content

[0004] This utility model overcomes the shortcomings of the prior art. Its structure is reasonably designed. By setting the water tank shell to extend or retract relative to the machine shell, it is easy to operate and more portable.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cleaner includes a housing, a circuit board and a battery and a pump body electrically connected to the circuit board are disposed inside the housing, a control button electrically connected to the circuit board is disposed on the housing, a nozzle that can be housed in the housing or unfolded relative to the housing is hinged to the housing, the nozzle is connected to the water outlet of the pump body through a pipeline, a water tank shell that extends or retracts relative to the housing is provided on the outer sliding cover of the housing, a water inlet is provided at one end of the housing relative to the water tank shell in the sliding direction, a connecting port is provided on the water inlet, the connecting port is connected to the water inlet of the pump body through a pipeline, a water storage cavity is formed between the water inlet and the water tank shell, and a water inlet communicating with the water storage cavity is provided on the water tank shell.

[0007] By adopting the above technical solution, the water tank shell can extend or retract relative to the main body. In use, the water tank shell can be extended first, water can be poured into the inlet, then the nozzle can be unfolded, and the control button can be pressed to perform a water cleaning operation, specifically for cleaning the bottom after defecation. After use, the nozzle can be rotated back into the main body, and then the water tank shell can be retracted and placed back on the main body, making it easy to carry and store. A water storage cavity is formed between the water tank shell and the water inlet. This water storage cavity can be formed after the water tank shell extends relative to the main body, or it can be present even when the water tank shell is not extended. When the main body is extended to its maximum position, the water storage cavity has its maximum water storage capacity.

[0008] Preferably, a recessed cavity is formed on the water inlet, and the connecting port is located at the bottom of the recessed cavity.

[0009] By adopting the above technical solution, the recessed cavity is specifically designed to converge towards the inside of the casing, and the connecting port is located at the bottom of the recessed cavity. This allows the water in the outlet cavity to enter the connecting port more quickly and smoothly, preventing water from accumulating inside the water tank casing after use and avoiding the problem of bacteria growing inside the water tank casing and making it difficult to clean.

[0010] Preferably, the water tank shell is rotatably equipped with a cover plate that inserts into the water inlet at the water inlet position. The cover plate is provided with an air inlet and a one-way valve plate that allows only external air to enter the water tank shell.

[0011] By adopting the above technical solution, the cover plate is located at the water inlet. When water needs to be added to the water tank, the cover plate is rotated open to expose the water inlet. During use, the cover plate covers the water inlet. The one-way valve and air inlet are designed so that the one-way valve opens only when the external air pressure is greater than the internal pressure of the water tank, allowing external air to enter the water tank and thus balancing the air pressure inside and outside the tank, enabling the pump to operate smoothly. Under other circumstances, the one-way valve remains closed to prevent water from overflowing from the water tank.

[0012] Preferably, the control buttons are only visible after the water tank housing extends relative to the machine housing.

[0013] By adopting the above technical solution, this setting can effectively protect the control buttons and prevent accidental operation when they are not in use.

[0014] Preferably, a limiting component is provided between the housing and the water tank housing to limit the position of the water tank housing extending or retracting relative to the housing.

[0015] By adopting the above technical solution, the limiting component can be a matching convex and groove structure, which can limit the initial position and the maximum extended position of the water tank shell, or limit multiple positions during the extension process.

[0016] Preferably, a filter screen is provided on the casing at the connection port.

[0017] By adopting the above technical solution, the filter screen can filter out small particles or impurities inside the water tank shell, preventing them from entering the pump body and damaging it.

[0018] Preferably, an annular sealing ring is provided between the water tank shell and the machine shell, and an O-ring is provided between the cover plate and the water inlet.

[0019] By adopting the above technical solution, this design can achieve a good sealing effect and prevent water leakage.

[0020] Preferably, the battery is a rechargeable battery, and the casing is provided with a charging interface.

[0021] By adopting the above technical solution, the battery can be easily charged and is convenient to use.

[0022] The beneficial effects of this utility model are:

[0023] This utility model has a reasonable structural design. By setting the water tank shell to extend or retract relative to the machine shell, it is easy to operate and more portable. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figure 1-10 As shown, a cleaner includes a housing 1, inside which is disposed a circuit board 11, a battery 12 and a pump body 13 electrically connected to the circuit board 11. A control button 14 electrically connected to the circuit board 11 is disposed on the housing 1. A nozzle 15 is hinged to the housing 1 and can be housed in the housing 1 or unfolded relative to the housing 1. The nozzle 15 is connected to the water outlet 131 of the pump body 13 through a pipeline. A water tank shell 2 is provided on the outer sliding cover of the housing 1, which extends or retracts relative to the housing 1. One end of the housing 1 relative to the water tank shell 2 in the sliding direction is a water inlet 3. A connecting port 31 is provided on the water inlet 3, which is connected to the water inlet 132 of the pump body 13 through a pipeline. A water storage cavity 4 is formed between the water inlet 3 and the water tank shell 2. A water inlet 21 communicating with the water storage cavity 4 is provided on the water tank shell 2.

[0037] By adopting the above technical solution, the water tank shell 2 can extend or retract relative to the housing 1. In use, the water tank shell 2 can be extended first, and water can be injected into the inlet 21. Then, the nozzle 15 can be unfolded, and the control button 14 can be operated to perform water washing operations. Specifically, it can be used to wash the bottom after defecation. After use, the nozzle 15 can be rotated and stored back into the housing 1, and then the water tank shell 2 can be retracted and placed back on the housing 1, which is convenient for carrying and storage. Among them, since a water storage cavity 4 is formed between the water tank shell 2 and the water inlet 3, the water storage cavity 4 can be formed after the water tank shell 2 extends relative to the housing 1, or it can be present when the water tank shell 2 does not extend from the housing 1. When the housing 1 is extended to the maximum position, the water storage cavity 4 has the largest volume for storing water.

[0038] A recessed cavity 32 is formed on the water inlet 3, and a connecting port 31 is located at the bottom of the recessed cavity 32. Specifically, the recessed cavity 32 can be arranged to converge towards the inside of the housing 1, and the connecting port 31 is located at the bottom of the recessed cavity 32. This allows the water in the water outlet cavity to enter the connecting port 31 more quickly and smoothly, and prevents water from accumulating inside the water tank housing 2 after use, thus preventing the problem of bacteria growing inside the water tank housing 2 and making it difficult to clean.

[0039] Furthermore, the water tank shell 2 is rotatably equipped with a cover plate 5 inserted into the water inlet 21. The cover plate 5 has an air inlet 51 and a one-way valve plate 52 that allows only external air to enter the water tank shell 2. The cover plate 5 is located at the water inlet 21. When water needs to be added to the water tank shell 2, the cover plate 5 is rotated open to expose the water inlet 21 for water filling. During use, the cover plate 5 covers the water inlet 21. The one-way valve plate 52 and the air inlet 51 are designed so that the one-way valve plate 52 opens only when the external air pressure is greater than the internal pressure of the water tank shell 2, allowing external air to enter the water tank shell 2, thereby balancing the air pressure inside and outside the water tank shell 2 and enabling the pump body 13 to work smoothly. Under other circumstances, the one-way valve plate 52 is always in the closed state of the air inlet 51 to prevent water from overflowing from the water tank shell 2.

[0040] The control button 14 is only exposed after the water tank housing 2 extends relative to the machine housing 1. This design effectively protects the control button 14 and prevents accidental operation when it is not in use.

[0041] Among them, a limiting component 6 is provided between the housing 1 and the water tank housing 2 to limit the position of the water tank housing 2 extending or retracting relative to the housing 1. The limiting component 6 can be a matching convex and groove structure, which can limit the initial position and the maximum extended position of the water tank housing 2, or limit multiple positions during the extension process.

[0042] A filter screen 33 is provided on the housing 1 at the communication port 31. The filter screen 33 can filter out small particles or impurities in the water tank housing 2 and prevent them from entering the pump body 13 and damaging the pump body 13.

[0043] Furthermore, an annular sealing ring 7 is provided between the water tank shell 2 and the machine shell 1, and an O-ring 8 is provided between the cover plate 5 and the water inlet 21. This arrangement provides a good seal and prevents water leakage. The battery 12 is a rechargeable battery 12, and a charging interface 16 is provided on the shell, which facilitates charging the battery 12 and makes it convenient to use.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
