Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a cleaning device. Background Art

[0002] At present, as a cleaning device that can sterilize, remove mites and vacuum, the mite-removing vacuum cleaner has more and more functions, and therefore, the mite-removing vacuum cleaner is being used more and more widely.

[0003] The mite-removing vacuum cleaner collects dust by setting a dust cup, and the dust cup has various dust cup locking structures. For example, some have a dust cup locking button set from the front top of the handle, and some have a button set in the vertical direction of the front end of the handle to lock the dust cup. Among them, when a button is set at the top of the front end of the handle, the button is pressed downward, so the mite vacuum cleaner needs to be placed flat on a supporting plane, such as on a sofa, bed, etc. If it is not placed on a supporting plane, it will be difficult to apply force. When pressing the button downward, the force is downward. When there is no upward supporting force under the mite vacuum cleaner, there will be a bad user experience, or you can only hold the mite vacuum cleaner with one hand and press the button with the other hand; in this way, if you need to hold the mite vacuum cleaner with one hand and press the button with the other hand, you cannot hold the dust cup at the same time, which is generally a bad experience; furthermore, if the button is set in the vertical direction at the front end, the hand needs to bypass the front end of the handle to press the button, and when pressing the button, the direction of the force is backward, and a forward force is needed to balance to prevent the mite vacuum cleaner from retreating. Therefore, external force is also needed to complete the release of the dust cup lock button, which is not a good experience either. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of uneven force on the dust cup of the dust collector in the prior art when unlocking, thereby providing a cleaning device with balanced force when unlocking the dust cup.

[0047] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] Embodiment 1

[0049] As Figure 1 and Figure 5 shown, a cleaning device includes: a handle 1, a dust cup 2, and a lock 3. The dust cup 2 is provided with a locking tongue 21. The lock 3 includes a first button 31, a second button 32, and a lock groove 33. The lock groove 33 is located inside the handle 1. The first button 31 and the second button 32 are correspondingly arranged on opposite sides of the handle 1 to drive the lock groove 33 to lock or unlock the locking tongue 21.

[0050] As Figure 5As shown in the figure, the above-mentioned cleaning device further includes a housing 4. The handle 1 is bent and connected to the housing 4. An installation groove 41 is provided at the top of the housing 4. A dust cup 2 can be placed in the installation groove 41. A locking tongue 21 is provided on the outer side wall of the dust cup 2. Among them, the locking tongue 21 includes a rod structure and a convex head provided at the end of the rod structure. A hole 131 is provided on the side of the handle 1 facing the dust cup 2 so that the locking tongue 21 passes through and extends into the handle 1 to cooperate with the locking groove 33 for locking or unlocking. A first button 31 is provided on one side of the end of the handle 1 close to the dust cup 2, and a second button 32 is provided on the other side. The first button 31 and the second button 32 are arranged opposite to each other. When unlocking the dust cup 2, the first button 31 and the second button 32 on the left and right sides are pressed simultaneously, then the left and right sides of the handle 1 are simultaneously subjected to the same magnitude and opposite direction forces. Therefore, by the balanced acting force acting on the first button 31 and the second button 32 on the opposite sides, no additional force needs to be provided to balance the pressure of pressing the buttons, and the dust cup 2 can be easily unlocked, improving the user experience.

[0051] Among them, continuing to combine Figure 1 and Figure 2 As shown in the figure, the lock 3 further includes an elastic member 36. The elastic member 36 is connected to the first button 31 and the second button 32. It can be understood that because the elastic member 36 has elasticity, when pressing the first button 31 and the second button 32, when the external force is greater than the elastic force of the elastic member 36, the first button 31 and the second button 32 can be pushed to move synchronously inward. Among them, the elastic member 36 can be a spring, such as a compression spring. One end of the spring is connected to the first button 31, and the other end of the spring is connected to the second button 32.

[0052] Specifically, as Figure 2 shown in the figure, both the first button 31 and the second button 32 are provided with pressing columns 303. Button holes 101 are respectively provided on the opposite sides of the handle 1 for the corresponding pressing columns 303 to pass through. An installation hole 304 is provided in the pressing column 303. The elastic member 36 is connected to the inner wall of the installation hole 304, making the connection of the elastic member 36 more firm. At the same time, the elastic member 36 partially extends into the installation hole 304, making the first button 31 and the second button 32 move more smoothly and be more easily balanced in force during the process of pressing or extending outward.

[0053] When the dust cup 2 is in the locked state, at this time, the pressing columns 303 of the left and right two buttons protrude from both sides of the handle 1, and the spring in the middle is in the extended state. The spring pushes the first button 31 and the second button 32 outward, thereby driving the first opening groove 331 and the second opening 332 to move towards the middle, realizing locking the locking tongue 21, and thus achieving the effect of locking the dust cup.

[0054] When the dust cup 2 is in the unlocked state, at this time, the pressing columns 303 of the left and right buttons are flush with or slightly protrude from the opposite sides of the handle 1, the middle spring is in a compressed state, the first button 31 and the second button 32 are pressed from both sides towards the middle, thereby driving the first opening groove 331 and the second opening groove 332 to move from the middle to both sides, so as to unlock the lock tongue 21, achieving the effect of unlocking the dust cup 2.

[0055] Further, as Figure 2 shown, the first button 31 is provided with a first opening groove 331, the second button 32 is provided with a second opening groove 332, the first opening groove 331 and the second opening groove 332 face each other to form a lock groove 33, the first button 31 and the second button 32 cross each other, so that when the first button 31 and the second button 32 extend outwards, the lock groove 33 locks the lock tongue 21, or when the first button 31 and the second button 32 are pressed inwards, the lock groove 33 unlocks the lock tongue 21.

[0056] The above-mentioned first opening groove 331 is provided on the first button 31, the second opening groove 332 is provided on the second button 32, the first button 31 and the second button 32 cross each other. When the first button 31 and the second button 32 extend in opposite directions, the first opening groove 331 and the second opening groove 332 approach each other, so as to lock the lock tongue 21. When the first button 31 and the second button 32 are pressed inwards, the first button 31 and the second button 32 move relatively inwards, then the first opening groove 331 and the second opening groove 332 move away from each other, so as to unlock the lock tongue 21.

[0057] Specifically, as Figure 2 and Figure 3 shown, the first button 31 includes a first moving part 311, a first connecting part 313 and a first linkage part 312. The first connecting part 313 connects the first moving part 311 and the first linkage part 312. The first linkage part 312 is provided with a first opening groove 331 on the side facing the second linkage part 322; the second button 32 includes a second moving part 321, a second connecting part 323 and a second linkage part 322. The second connecting part 323 connects the second moving part 321 and the second linkage part 322. The second linkage part 322 is provided with a second opening groove 332 on the side facing the first linkage part 312; wherein, when the first button 31 is pressed, the first moving part 311 and the second moving part 321 approach each other, while the first linkage part 312 and the second linkage part 322 move away from each other. When the first button 31 extends outwards, the first moving part 311 and the second moving part 321 move away from each other, while the first linkage part 312 and the second linkage part 322 approach each other.

[0058] As Figure 7As shown, the above-mentioned first moving part 311, first connecting part 313, and first linkage part 312 can all be in a plate-like structure, which can save installation space. Moreover, the first moving part 311, first connecting part 313, and first linkage part 312 can be integrally provided, wherein the first moving part 311 and the first linkage part 312 are respectively located on opposite sides of the first connecting part 313. Similarly, as Figure 8 shown, the second moving part 321, second connecting part 323, and second linkage part 322 can all be in a plate-like structure and can be integrally provided, wherein the second moving part 321 and the second linkage part 322 are respectively located on opposite sides of the second connecting part 323.

[0059] More specifically, as Figure 2 and Figure 4 shown, the first moving part 311 and the first linkage part 312 are respectively perpendicular to the first connecting part 313, and the second moving part 321 and the second linkage part 322 are respectively perpendicular to the second connecting part 323. The first opening groove 331 is recessed at one end of the first linkage part 312 away from the first connecting part 313, and the second opening groove 332 is recessed at one end of the second linkage part 322 away from the second connecting part 323, so as to facilitate locking the lock tongue 21.

[0060] Furthermore, as Figure 6 shown, the lock 3 further includes a first limiting structure 34. The first limiting structure 34 is provided in the handle 1, and the first limiting structure 34 is located between the first moving part 311 and the second moving part 321. The lock 3 further includes a support frame 37. The support frame 37 is provided in the handle 1. Specifically, the support frame 37 is integrally provided with the handle 1. The support frame 37 includes a plate body structure, which can be used to support the first button 31 and the second button 32, and the first button 31 and the second button 32 can slide on the support frame 37 to protrude outward or retract inward. The first limiting structure 34 is provided between the first moving part 311 and the second moving part 321, which can prevent the first moving part 311 and the second moving part 321 from colliding with each other when moving relatively inward. Among them, the first limiting structure 34 is in a strip-like structure, and the structure is simple.

[0061] Even further, as Figure 7 shown, the lock 3 further includes a second limiting structure 35. The second limiting structure 35 is provided in the handle 1 to prevent the first button 31 and the second button 32 from interfering with the inner wall of the handle 1. Among them, when the first button 31 and the second button 32 are pressed, the first linkage part 312 and the second linkage part 322 move outward respectively. At this time, due to the provision of the second limiting structure 35, the first linkage part 312 and the second linkage part 322 contact the second limiting structure 35, thereby avoiding touching the inner side wall of the handle 1.

[0062] Specifically, a plurality of limiting ribs are provided on the inner side walls of the opposite sides of the handle 1 to form a second limiting structure 35. Among them, the plurality of limiting ribs are arranged at intervals in the extending direction of the inner side wall of the handle 1, which can not only play a role in limiting the first button 31 and the second button 32, but also has a simple structure.

[0063] Furthermore, in order to make the first button 31 and the second button 32 move more smoothly and not get stuck easily during the pressing process, a guiding groove 301 is provided on the first connecting portion 313 and / or the second connecting portion 323, and a guiding member 302 for cooperating with the guiding groove 301 for guiding is provided in the handle 1. Among them, the guiding member 302 can be a guiding plate, so that the guiding groove 301 moves along the guiding plate.

[0064] Further, the lock 3 further includes a guiding structure 38, the guiding structure 38 is provided on the support frame 37, and the first button 31 and the second button 32 are respectively slidably connected to the guiding structure 38 in the sliding direction. Through the guiding structure 38, the first button 31 and the second button 32 can move more smoothly and are more easily subjected to balanced force during the sliding process.

[0065] Among them, the guiding structure 38 includes at least one guiding rib, and the guiding rib extends along the sliding direction, which simplifies the structure of the guiding structure 38. The plurality of guiding ribs can be arranged at intervals, making the overall structure more concise. Specifically, the guiding structure 38 includes a first guiding rib 381, a second guiding rib 382, a third guiding rib 383 and a fourth guiding rib 384. The first guiding rib 381 can be used to guide the rear ends of the first button 31 and the second button 32, the second guiding rib 382 can be used to guide the pressing column 303, the third guiding rib 383 can be used to guide the front ends of the first connecting portion 313 and the second connecting portion 323, and the fourth guiding rib 384 can be used to guide the first linkage portion 312 and the second linkage portion 322.

[0066] Further, the inner side wall of the locking groove 22 is inclined, which can form a guiding effect on the locking tongue 21. Among them, the outer side wall of the convex head of the locking tongue 21 is also inclined to be adapted to the locking groove 22. As Figure 1 and Figure 2 shown, the inner side wall of the locking groove 33 and the outer side wall of the locking tongue 21 are both conical, so as to facilitate locking the locking tongue 21 into the locking groove 33. When the dust cup 2 is to be installed to lock the dust cup 2, as long as the dust cup 2 is pushed against the inclined wall of the locking groove 33, without pressing the first button 31 and the second button 32, the dust cup 2 can be locked through the interaction between the inclined wall on the locking tongue 21 and the inclined wall on the locking groove 33.

[0067] The above-mentioned cleaning device includes a dust mite remover. The dust mite remover has a UV sterilization module, and the UV sterilization module has a control mechanism. The control mechanism measures the distance between the bottom shell and the surface to be cleaned through a distance sensor, and when the distance exceeds the set value, the UV sterilization module is turned off through the controller.

[0068] Further, as Figure 5 shown, the handle 1 includes: a handle bottom shell 11, a handle top shell 12 and a handle cover plate 13. A hole 131 for the lock tongue 21 to pass through is provided on the handle cover plate 13. The handle top shell 12 and the handle bottom shell 11 are buckled with each other to enclose a cavity, and the lock 3 is arranged in the cavity.

[0069] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
