Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaners, specifically relating to a top cover assembly for a water tank of a cleaning device. Background Technology

[0002] Existing cleaning equipment, such as fabric cleaning machines, generally includes a main unit, a water tank mounted on the main unit, and cleaning components for performing cleaning operations. The water tank is open from the top and has a cover that can be opened and closed. When the cover is closed, the water tank forms a closed water storage chamber, and when the cover is opened, the wastewater in the water tank can be poured out.

[0003] However, in actual use, the water tank is usually detachably installed on the main unit from the bottom. When the vacuum cleaner is moved as a whole, the inertial force generated by the sloshing of water in the water tank causes the center of gravity to be unstable, making it difficult to ensure the stability of the connection structure between the water tank and the main unit. There is a risk that the water tank may shake or fall off, requiring the user to hold the dust cup steady at all times, which is very inconvenient and results in a poor user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved top cover assembly for a water tank of a cleaning device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A top cover assembly for a water tank in a cleaning device is disclosed. The water tank is installed above the main unit and has a vertically penetrating limiting groove. The main unit has a limiting post that inserts into the limiting groove from bottom to top, wherein the limiting post has a limiting end that protrudes upward from the limiting groove. The top cover assembly includes a cover body and a locking unit disposed on the cover body. The cover body covers the top of the water tank. The locking unit includes a first locking component that locks or unlocks the cover body relative to the water tank and a second locking component that locks or unlocks the cover body relative to the limiting end. As the cover body locks relative to the water tank and the limiting end respectively, a lock is formed between the water tank and the main unit in the horizontal and vertical directions.

[0007] According to a specific embodiment and preferred aspect of this utility model, the cover includes a cover body and a handle disposed on the upper surface of the cover body, wherein a second locking component is disposed on the handle and is operated with one hand. This facilitates one-handed, one-button unlocking of the water tank and the main unit.

[0008] Preferably, the cover body also has an insertion interface that communicates with the top of the limiting groove, with the limiting end extending out of the insertion interface from bottom to top. This achieves a foolproof design, ensuring that the cover body is installed in place on the first attempt and guaranteeing that the first and second locking components are precisely aligned with the limiting ends of the water tank and the main unit.

[0009] Specifically, the insertion interface is located at one end near the handle, and the limiting end is recessed inward from one side to form a locking groove; the second locking component includes a locking module movably connected to the handle, wherein the top of the locking module has an operating part and the side near the limiting end has a locking tongue. By moving the operating part and driving the locking tongue to insert into or disengage from the locking groove, the locking module and the limiting end are locked or unlocked relative to each other in the vertical direction.

[0010] Furthermore, the locking module is slidably connected to one end of the handle along its length; the second locking component also includes an elastic element that abuts against the handle and the locking module, wherein the elastic element drives the locking module to have a tendency to move towards the limiting end. Here, when the user holds the handle, it is convenient to operate the locking module with the thumb to unlock, and it can automatically lock when the user releases the handle, which is very simple, convenient, and ergonomic.

[0011] Preferably, the lid body has an inwardly recessed groove formed on its top surface, and the handle is connected above the groove. This increases the operating space, making it easier for the user to insert their hand into the space between the handle and the lid body for gripping.

[0012] According to another specific embodiment and preferred aspect of this utility model, a first fastening portion and a second fastening portion are respectively formed on opposite sides of the water tank. The first locking component includes a first latch and a second latch located on opposite sides of the cover and correspondingly cooperating with the first fastening portion and the second fastening portion. The first latch and the second latch engage or disengage with the first fastening portion and the second fastening portion, thereby locking or unlocking the cover relative to the water tank in the horizontal and vertical directions. Here, by forming a fastening on opposite sides, the connection stability is strong, which is beneficial to improving the sealing performance of the cover to the water tank.

[0013] Preferably, there are multiple first fastening parts and first buckles, which are distributed at intervals along the corresponding sides of the cover.

[0014] Specifically, the water tank is recessed inward from one side to form a limiting groove, and multiple first fastening parts and first latches are distributed on opposite sides of the limiting groove. This facilitates quick positioning and assembly of the water tank on the main unit, while the first fastening parts and first latches arranged on both sides of the limiting groove facilitate locking or unlocking operations.

[0015] Furthermore, the second latching part gradually widens from top to bottom, and the second buckle has a lever-like part that curves away from the water tank from the bottom. This facilitates unlocking by levering.

[0016] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] Existing water tanks are typically detachably mounted to the main unit from the bottom. When the vacuum cleaner is moved, the inertial force generated by the sloshing of water in the tank causes instability, making it difficult to ensure the stability of the connection between the water tank and the main unit. This poses a risk of the water tank shaking or falling off, requiring the user to constantly hold the dust cup steady, which is inconvenient and results in a poor user experience. This application addresses these shortcomings by redesigning the top cover assembly for the water tank, cleverly resolving the deficiencies of existing technologies. With this top cover assembly, the water tank is mounted on the main unit, effectively limiting the position of the main unit. The column is inserted into the limiting groove formed by the water tank from bottom to top, keeping the limiting end of the column protruding upwards from the limiting groove; the cover is placed on top of the water tank, and the first locking component and the second locking component are operated respectively, so that the cover is locked relative to the water tank and the limiting end respectively, and the water tank and the main unit are locked in the horizontal and vertical directions; when unlocking, the cover is unlocked relative to the limiting end by the second locking component, so that the cover keeps the top of the water tank closed and the water tank can be removed from the main unit; the cover is unlocked relative to the water tank by the first locking component, so that the cover can be opened and the top of the water tank can be opened for easy pouring. Therefore, compared with the prior art, this utility model has two advantages. First, based on the limiting post formed on the main unit passing upward through the limiting groove formed on the water tank, the water tank and the limiting post are locked together to achieve a lock between the water tank and the main unit in the horizontal and vertical directions, which effectively improves the installation stability of the water tank and makes it easy for users to move and use it. Second, based on the integration of the first and second locking components on the cover, the structure is simple, the operation is convenient, and the user experience is effectively improved.

[0030] like Figures 1 to 4 As shown, the top cover assembly for the water tank of the cleaning equipment involved in this embodiment includes a cover body 1 and a locking unit 2 disposed on the cover body 1.

[0031] Specifically, in this embodiment, the water tank X is installed on the main unit J and is open from the top. The water tank X has a vertically penetrating limiting groove X0, and the main unit J has a limiting post J0 that is inserted into the limiting groove X0 from bottom to top. The limiting post J0 has a limiting end J00 that protrudes upward from the limiting groove X0.

[0032] In this example, the cover 1 includes a cover body 10 covering the top of the water tank X and a handle 11 on the upper surface of the cover body 10. The locking unit 2 includes a first locking component 21 that locks or unlocks the cover 1 relative to the water tank X and a second locking component 22 that locks or unlocks the cover 1 relative to the limiting end J00. As the cover 1 is locked relative to the water tank X and the limiting end J00 respectively, a lock is formed between the water tank X and the main unit J in the horizontal and vertical directions.

[0033] In some specific embodiments, the first locking component 21 is disposed on the cover body 10, and the second locking component 22 is disposed on the handle 11 and is operated with one hand. This facilitates one-handed one-button unlocking of the water tank and the main unit.

[0034] For ease of implementation, the lid body 10 has an inwardly recessed groove 100 formed on its top surface, and the handle 11 is connected above the groove 100. This increases the operating space, making it easier for the user to insert their hand into the space between the handle and the lid body for gripping.

[0035] In this example, the water tank X has a first fastening portion X1 and a second fastening portion X2 formed on opposite sides of the handle 11 along its length. The first locking component 21 includes a first latch 211 and a second latch 212 located on opposite sides of the cover body 10 and correspondingly engaging with the first fastening portion X1 and the second fastening portion X2. The first latch 211 and the second latch 212 engage or disengage with the first fastening portion X1 and the second fastening portion X2, thereby locking or unlocking the cover body 1 relative to the water tank X in the horizontal and vertical directions. Here, by forming a fastening on opposite sides, the connection stability is strong, which helps to improve the sealing performance of the cover body to the water tank.

[0036] In some specific embodiments, there are multiple first fastening portions X1 and first latches 211, which are spaced apart along the corresponding sides of the cover body 10. In this embodiment, there are two first fastening portions X1 and two first latches 211. The water tank X is recessed inward from one side to form a limiting groove X0, and the two sets of first fastening portions X1 and first latches 211 are distributed on opposite sides of the limiting groove X0. This facilitates quick positioning and assembly of the water tank on the main unit, and the first fastening portions and first latches arranged on both sides of the limiting groove facilitate locking or unlocking operations.

[0037] Meanwhile, the second latching portion X2 gradually widens from top to bottom, and the second latch 212 has a lever portion b1 that bends away from the water tank X from the bottom. This facilitates unlocking by levering. It should be noted that in this embodiment, both the first and second latches are plastic parts. By levering the lever portion b1, the second latch 212 deforms and disengages from the second latching portion X2. In other specific embodiments, the first locking component 21 can also use any other conventional locking component to lock or unlock the cover body 10 to the top of the water tank.

[0038] To further facilitate implementation, the cover body 10 also has an insertion interface 101 that communicates with the top of the limiting groove X0, and the limiting end J00 extends out of the insertion interface 101 from bottom to top. Here, a foolproof design is implemented to ensure that the cover body is installed in place in one go and to ensure that the first and second locking components are precisely aligned with the limiting ends of the water tank and the main unit.

[0039] In some specific embodiments, the insertion interface 101 is located at one end near the handle 11, and the limiting end J00 is recessed inward from one side to form a locking groove c; the second locking component 22 includes a locking module 220 movably connected to the handle 11 and an elastic member 221 abutting between the handle 11 and the locking module 220, wherein the top of the locking module 220 has an operating part b2 and a locking tongue s is formed on the side near the limiting end J00. By moving the operating part b2 and driving the locking tongue s to insert into or disengage from the locking groove c, the locking module 220 and the limiting end J00 are locked or unlocked relative to each other in the vertical direction.

[0040] Furthermore, a movable groove 110 is formed at one end of the handle 11. The locking module 220 is slidably connected to the movable groove 110 at one end of the handle 11 along the length direction of the handle 11. By actuating the operating part b2, the locking module 220 is driven to slide along the length direction of the handle 11. To improve the sliding guidance, guide grooves extending along the length direction of the handle 11 are formed on opposite sides of the movable groove 110. The locking module 220 is inserted into the guide grooves from both sides and slides along the guide grooves. The elastic element 221 is a spring and is set in the movable groove 110. The elastic element 221 drives the locking module 220 to have a tendency to move towards the limiting end J00. Here, when the user carries the handle, it is convenient to operate the locking module to unlock with the thumb, and it can be automatically locked when the user releases the handle. It is very simple, convenient, and ergonomic.

[0041] In summary, after adopting this top cover assembly, the water tank is installed on the main unit, and the limiting post formed by the main unit is inserted from bottom to top into the limiting groove formed by the water tank, keeping the limiting end of the limiting post protruding upwards from the limiting groove; the cover is placed on top of the water tank, and the first locking component and the second locking component are operated respectively, so that the cover is locked relative to the water tank and the limiting end respectively, and the water tank and the main unit are locked in the horizontal and vertical directions; when unlocking, the cover is unlocked relative to the limiting end by the second locking component, so that the cover keeps the top of the water tank closed and the water tank can be removed from the main unit; the cover is unlocked relative to the water tank by the first locking component, so that the top of the water tank is opened for easy pouring. Therefore, compared with the prior art, this utility model has several advantages.
