Description

Technical Field

[0001] This invention relates to the field of dust removal technology, and in particular to a vacuum cleaner. Background Technology

[0002] As people's living standards improve, their demands for a clean environment also increase, especially in home cleaning, where thorough cleaning of the interior is required. However, traditional methods cannot meet the cleanliness needs of the interior and are time-consuming and laborious. Vacuum cleaners, on the other hand, can effectively and quickly clean stains and dirt, meeting people's requirements. Therefore, they are widely used.

[0003] The dust collection unit is the component in a vacuum cleaner used to collect dust. When the dust volume reaches the maximum collection capacity of the dust collection unit, it needs to be cleaned. Generally, the dust collection unit is connected to the main unit via clips. When cleaning the dust collection unit is needed, the clips are operated to separate it from the main unit. After cleaning, the clips are operated again to re-lock the dust collection unit to the main unit. This method makes the process of disassembling and assembling the dust collection unit rather cumbersome. Summary of the Invention

[0004] Therefore, it is necessary to provide a vacuum cleaner that makes it easier to disassemble and assemble the dust collection component, addressing the problem that the process of disassembling and assembling the dust collection component in traditional vacuum cleaners is quite cumbersome.

[0005] A vacuum cleaner, comprising:

[0006] Main unit and dust collection components;

[0007] A self-locking device is assembled on one of the main unit and the dust collection component;

[0008] The main unit and the other of the dust collection components can controllably press the self-locking device to switch the self-locking device between a locked state and an unlocked state;

[0009] In the locked state, the self-locking device locks the dust collection component and the main unit.

[0010] In the unlocked state, the self-locking device allows the dust collection component to be separated from the main unit.

[0011] The aforementioned vacuum cleaner allows the dust collection component to be assembled onto the main unit or detached from the main unit by pressing it. Compared to the existing technology where the dust collection component is fastened to the main unit, this method facilitates the assembly and disassembly of the dust collection component.

[0012] In one embodiment, the self-locking device includes a pressing mechanism and a self-locking mechanism that cooperate with each other, wherein the main unit and the other of the dust collection components can controllably press the pressing mechanism to switch the self-locking device between the locked state and the unlocked state;

[0013] In the locked state, the self-locking mechanism cooperates with the pressing mechanism to lock the dust collection component and the main unit; in the unlocked state, the self-locking mechanism cooperates with the pressing mechanism to allow the dust collection component to separate from the main unit.

[0014] In one embodiment, the pressing mechanism includes a first base and a first slider, the first base being fixedly connected to one of the main unit and the dust collection component, and the first slider being slidably disposed on the first base;

[0015] The host and the other of the dust collection components can be controlled to press the first slider, causing the first slider to switch between a first position and a second position in a short time.

[0016] In the first position, the self-locking mechanism cooperates with the first slider to lock the dust collection component and the main unit; in the second position, the self-locking mechanism and the first slider allow the dust collection component to separate from the main unit.

[0017] In one embodiment, the pressing mechanism further includes a hook and a first elastic element. One end of the hook is movably connected to the first base. The first slider is provided with a first groove. The first groove is provided with a first limiting part and a second limiting part spaced apart along the pressing direction of the first slider. The other end of the hook can slide in the first groove and can be limited to the first limiting part and the second limiting part.

[0018] When the other end of the hook is limited to the first limiting part, the first slider is in the first position; when the other end of the hook is limited to the second limiting part, the first slider is in the second position; and the first elastic element is used to provide the restoring force for the first slider to switch between the first position and the second position.

[0019] In one embodiment, the self-locking mechanism includes a second base, a self-locking component, and a second elastic component. The second base is fixedly connected to one of the main unit and the dust collection component. The self-locking component is rotatably connected to the second base. The second elastic component is disposed between the self-locking component and the second base.

[0020] In the locked state, the self-locking member, under the deformation of the second elastic member, cooperates with the pressing mechanism to lock the dust collection member and the main unit; in the unlocked state, the deformation of the second elastic member returns to normal, allowing the self-locking member and the pressing mechanism to cooperate and separate the dust collection member from the main unit.

[0021] In one embodiment, the pressing mechanism has a first inclined surface and a flat surface, and the self-locking mechanism has a second inclined surface. In the locked state, the second inclined surface abuts against the first inclined surface, and the self-locking mechanism cooperates with the pressing mechanism to lock the dust collection component and the main unit. In the unlocked state, the second inclined surface abuts against the flat surface, and the self-locking mechanism cooperates with the pressing mechanism to allow the dust collection component to separate from the main unit.

[0022] In one embodiment, the self-locking device has a hook, and the other of the main unit and the dust collection component has a first mating part. In the locked state, the first mating part and the hook engage to lock the dust collection component and the main unit. In the unlocked state, the first mating part and the hook separate to allow the dust collection component to separate from the main unit.

[0023] In one embodiment, the self-locking device is fitted into one of the dust collection component and the main unit.

[0024] In one embodiment, the vacuum cleaner further includes a limiting device mounted on the dust collection component and / or the main unit, the limiting device having a released state and a limiting state;

[0025] In the released state, the limiting device allows the dust collection component to detach from the host, and in the limiting state, the limiting device restricts the dust collection component from detaching from the host.

[0026] In one embodiment, when in the limiting state, the limiting device restricts the self-locking device from switching from the self-locking state to the unlocking state.

[0027] In one embodiment, when the vacuum cleaner is powered on, the limiting device is in the limiting state, and when the vacuum cleaner is powered off, the limiting device is in the releasing state.

[0028] In one embodiment, the limiting device includes a second slider, a third elastic element and a suction element, one end of the third elastic element and the suction element are fixedly connected to one of the dust collection element and the main unit, and the other end of the third elastic element is fixedly connected to the second slider.

[0029] When the vacuum cleaner is powered on, the suction member overcomes the elastic force of the third elastic member to attract the second slider, causing the second slider to restrict the dust collection member from detaching from the main unit; when the vacuum cleaner is powered off, the third elastic member returns to its original shape and causes the second slider to move, allowing the second slider to separate the dust collection member from the main unit.

[0030] In one embodiment, the limiting device is assembled inside the dust collection component and / or the main unit. Attached Figure Description

[0056] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0057] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0059] See Figure 1 An embodiment of the present invention provides a vacuum cleaner 100, including a main unit 10 and a dust collection component 20. The dust collection component 20 is detachably connected to the main unit 10. When the dust collected in the dust collection component 20 reaches its maximum dust collection capacity, the user can remove the dust collection component 20 from the main unit 10 for cleaning.

[0060] The vacuum cleaner 100 also includes a self-locking device 30, which is mounted on one of the main unit 10 and the dust collection component 20. The other of the main unit 10 and the dust collection component 20 can be controllably pressed to switch the self-locking device 30 between a locked state and an unlocked state. In the locked state, the self-locking device 30 locks the dust collection component 20 and the main unit 10; in the unlocked state, the self-locking device 30 allows the dust collection component 20 to separate from the main unit 10.

[0061] Thus, when the self-locking device 30 is in the locked state, it can be switched from the locked state to the unlocked state by pressing the self-locking device 30 by the main unit 10 or the dust collection component 20, so as to facilitate the removal of the dust collection component 20 from the main unit 10; when it is necessary to assemble the dust collection component 20 onto the main unit 10, it can also be switched from the unlocked state to the locked state by pressing the self-locking device 30 by the main unit 10 or the dust collection component 20, so as to facilitate the assembly of the dust collection component 20 onto the main unit 10.

[0062] The above configuration allows the dust collection component 20 to be assembled onto the main unit 10 or disassembled from the main unit 10 by pressing. Compared with the existing technology where the dust collection component 20 is fastened and fixed to the main unit 10, this facilitates the assembly and disassembly of the dust collection component 20.

[0063] In one embodiment, the self-locking device 30 is mounted on the main unit 10. When the dust collection component 20 needs to be mounted on the main unit 10, the dust collection component 20 presses the self-locking device 30 to switch it from the unlocked state to the locked state, thereby locking the dust collection component 20 to the main unit 10. When the dust collection component 20 needs to be removed from the main unit 10, the dust collection component 20 presses the self-locking device 30 again to switch it from the locked state to the unlocked state, thereby removing the dust collection component 20 from the main unit 10.

[0064] It is understood that in some other embodiments, the self-locking device 30 may also be mounted on the dust collection component 20. When the dust collection component 20 needs to be mounted on the main unit 10, the main unit 10 presses the self-locking device 30 to switch it from the unlocked state to the locked state, thereby locking the dust collection component 20 to the main unit 10. When the dust collection component 20 needs to be removed from the main unit 10, the main unit 10 presses the self-locking device 30 again to switch it from the locked state to the unlocked state, thereby removing the dust collection component 20 from the main unit 10.

[0065] In one embodiment, to achieve a more aesthetically pleasing visual effect for the vacuum cleaner 100, the self-locking device 30 is fitted inside the main unit 10. Specifically, the main unit 10 includes a housing 11, and the self-locking device 30 is fitted inside the housing 11. It is conceivable that in other embodiments, the self-locking device 30 may also be fitted outside the housing 11, and the self-locking device 30 is not limited to being fitted onto the housing 11 of the main unit 10; this is not a limitation here.

[0066] See Figure 2 The self-locking device 30 includes a pressing mechanism 31 and a self-locking mechanism 32 that cooperate with each other. The dust collection component 20 can controllably press the pressing mechanism 31 to switch the self-locking device 30 between a locked state and an unlocked state. In the locked state, the self-locking mechanism 32 cooperates with the pressing mechanism 31 to lock the dust collection component 20 and the housing 11. In the unlocked state, the self-locking mechanism 32 cooperates with the pressing mechanism 31 to allow the dust collection component 20 to separate from the housing 11.

[0067] See Figure 3 The pressing mechanism 31 includes a first base 311 and a first slider 312. The first base 311 is fixedly connected to the outer casing 11, and the first slider 312 is slidably disposed on the first base 311. The dust collection component 20 can controllably press the first slider 312 to switch between a first position and a second position. In the first position, the self-locking mechanism 32 cooperates with the first slider 312 to lock the dust collection component 20 and the outer casing 11. In the second position, the self-locking mechanism 32 allows the dust collection component 20 to separate from the outer casing 11.

[0068] That is, when the first slider 312 is in the first position, the self-locking device 30 is in the locked state. At this time, the self-locking mechanism 32 cooperates with the first slider 312 to lock the dust collection component 20 and the outer shell 11. In the second position, the self-locking device 30 is in the unlocked state. At this time, the self-locking mechanism 32 cooperates with the first slider 312 to allow the dust collection component 20 to separate from the outer shell 11.

[0069] In one embodiment, the first position is positioned towards the outside relative to the second position. It is understood that in other embodiments, the first position may also be positioned away from the outside relative to the second position; this is not a limitation.

[0070] See Figure 2 and Figure 3 The pressing mechanism 31 also includes a hook 313 and a first elastic element 314. One end of the hook 313 is movably connected to the first base 311. The first slider 312 is provided with a first groove 3121. The first groove 3121 has a first limiting part 3122 and a second limiting part 3123 spaced apart along the pressing direction of the first slider 312 (see reference). Figure 4 The other end of the hook 313 can slide within the first groove 3121 and can be limited to the first limiting part 3122 and the second limiting part 3123.

[0071] When the other end of the hook 313 is limited to the first limiting part 3122, the first slider 312 is in the first position. At this time, the self-locking mechanism 32 cooperates with the first slider 312 to lock the dust collector 20 to the outer casing 11. When the other end of the hook 313 is limited to the second limiting part 3123, the first slider 312 is in the second position. At this time, the self-locking mechanism 32 cooperates with the first slider 312 to allow the dust collector 20 to separate from the outer casing 11. The first elastic member 314 is used to provide the restoring force for the first slider 312 to switch between the first position and the second position.

[0072] See Figure 2 Specifically, a second sliding groove 3111 is provided on the first base 311, and a first slider 312 is slidably disposed in the second sliding groove 3111. One end of the second sliding groove 3111 has an opening 3112. One end of a hook 313 is movably connected to the side wall of the second sliding groove 3111 opposite to the opening 3112, and the other end of the hook 313 is slidably disposed in the first sliding groove 3121. The dust collection component 20 presses the first slider 312 from the end of the second sliding groove 3111 with the opening 3112. A first elastic member 314 is disposed between the side wall connected to the hook 313 and the first slider 312.

[0073] Assuming that in the initial state, the first slider 312 is in the first position and the hook 313 is limited to the first limiting part 3122, the self-locking mechanism 32 cooperates with the first slider 312 to lock the dust collection component 20 and the outer shell 11.

[0074] When the dust collection component 20 presses the first slider 312, the first slider 312 slides in the second slide groove 3111 under the action of the pressing force, and the first elastic element 314 is compressed. At the same time as the first slider 312 slides in the second slide groove 3111, the other end of the hook 313 slides in the first slide groove 3121 and is finally limited to the second limiting part 3123. At this time, the first slider 312 is in the second position, and the self-locking mechanism 32 cooperates with the first slider 312 to allow the outer shell 11 of the dust collection component 20 to separate.

[0075] When the dust collection component 20 presses the first slider 312 again, the other end of the hook 313 slides in the first groove 3121 and is finally limited to the first limiting part 3122. At this time, the first slider 312 moves from the second position to the first position under the restoring force of the first elastic member 314. The self-locking mechanism 32 cooperates with the first slider 312 to lock the dust collection component 20 and the outer shell 11.

[0076] It should be noted that the slope height of the first groove 3121 is different at each point, so that the hook 313 can only move cyclically between the first limiting part 3122 and the second limiting part 3123 in a single direction.

[0077] See Figure 5The self-locking mechanism 32 includes a second base 321, a self-locking element 322, and a second elastic element 323 (see reference). Figure 2 The second base 321 is fixedly connected to the outer casing 11 and covers the first base 311 (see reference). Figure 6 The self-locking member 322 is rotatably connected to the second base 321, and the second elastic member 323 is disposed between the self-locking member 322 and the second base 321.

[0078] In the locked state, the self-locking member 322, under the deformation of the second elastic member 323, cooperates with the first slider 312 to lock the dust collector 20 and the outer shell 11. In the unlocked state, the deformation of the second elastic member 323 returns to normal, allowing the self-locking member 322 to cooperate with the first slider 312 to allow the dust collector 20 to separate from the outer shell 11.

[0079] Specifically, when the first slider 312 is in the first position, the second elastic element 323 is compressed, and the self-locking element 322 abuts against and fixes the first slider 312 under the action of the second elastic element 323, thereby locking the dust collector 20 and the outer shell 11; when the first slider 312 is in the second position, the second elastic element 323 returns to its original shape, and the self-locking element 322 cooperates with the first slider 312 to allow the dust collector 20 to separate from the outer shell 11.

[0080] Furthermore, the first slider 312 has a first inclined surface 3124 and a plane 3125 (see reference). Figure 2 The self-locking member 322 has a second inclined surface 3221. In the locked state, the hook 313 is limited to the first limiting portion 3122, and the second inclined surface 3221 abuts against the first inclined surface 3124 (see reference). Figure 7 and Figure 8 When the second elastic element 323 is compressed, the self-locking element 322 and the first slider 312 cooperate to lock the dust collector 20 and the outer casing 11. In the unlocked state, the second elastic element 323 returns, causing the self-locking element 322 to rotate relative to the second base 321, the hook 313 is limited to the first limiting part 3123, and the second inclined surface 3221 abuts against the plane 3125 (see reference). Figure 9 and Figure 10 The self-locking component 322 cooperates with the first slider 312 to allow the dust collection component 20 to separate from the outer casing 11.

[0081] In one embodiment, the self-locking member 322 has a hook 3222, and the dust collection member 20 has a first engaging portion 21. In the locked state, the first engaging portion 21 engages with the hook 3222 to lock the dust collection member 20 and the outer casing 11 (see reference). Figure 11 and Figure 12 In the unlocked state, the first mating part 21 separates from the hook 3222, allowing the dust collection part 20 to separate from the housing 11 (see...). Figure 13 and Figure 14It is conceivable that in some other embodiments, the self-locking member 322 may omit the hook 3222. In this case, the self-locking member 322 locks the dust collection member 20 and the outer shell 11 by engaging with the first mating part 21 through friction. This is not limited here.

[0082] Continue reading Figure 1 In one embodiment, the vacuum cleaner 100 further includes a limiting device 40, which is fitted onto the dust collection component 20 and / or the housing 11. The limiting device 40 has a limiting state and a releasing state. In the limiting state, the limiting device 40 restricts the dust collection component 20 from separating from the housing 11. In the releasing state, the limiting device 40 allows the dust collection component 20 to separate from the housing 11.

[0083] Since users typically push and pull the vacuum cleaner 100 back and forth, the dust collection component 20 may accidentally touch an arm or a table or chair during this process, causing the self-locking device 30 to unlock. In this case, the dust collection component 20 may easily separate from the outer casing 11. By setting the limiting device 40, the dust collection component 20 can be prevented from separating from the outer casing 11.

[0084] In order to make the vacuum cleaner 100 produce a more aesthetically pleasing visual effect, the limiting device 40 is also mounted inside the housing 11. It is understood that in some other embodiments, the limiting device 40 may also be mounted outside the housing 11, which is not limited here.

[0085] Specifically, when the vacuum cleaner 100 is powered on, the limiting device 40 is in a limited state; when the vacuum cleaner 100 is powered off, the limiting device 40 is in a released state, meaning that the limiting device 40 is electrically driven at this time. This prevents the dust collection component 20 from separating from the outer casing 11 during operation, and allows for easy removal of the dust collection component 20 from the outer casing 11 when the vacuum cleaner 100 is not in operation.

[0086] Of course, in other embodiments, the limiting device 40 can also be locked by a mechanical drive, which can achieve the same effect.

[0087] More specifically, in the limiting state, the limiting device 40 restricts the self-locking device 30 from switching from the self-locking state to the unlocking state. That is, when the dust collection component 20 is assembled on the housing 11, the dust collection component 20 cannot move forward or backward relative to the housing 11 under the action of the limiting device 40.

[0088] See Figure 15 and Figure 16 The limiting device 40 includes a second slider 41, a third elastic member 43 and a suction member 42 (such as a magnet). One end of the third elastic member 43 and the suction member 42 are fixedly connected to the outer shell 11, and the other end of the third elastic member 43 is fixedly connected to the second slider 41.

[0089] When the vacuum cleaner 100 is powered on, the suction member 42 overcomes the elastic force of the third elastic member 43 to attract the second slider 41, causing the second slider 41 to prevent the dust collection member 20 from detaching from the outer casing 11 (see...). Figure 17 and Figure 18 When the vacuum cleaner 100 is powered off, the third elastic element 43 returns to its original shape, causing the second slider 41 to move, allowing the dust collection element 20 to separate from the outer casing 11 (see...). Figure 19 and Figure 20 ).

[0090] In this specific embodiment, the third elastic element 43, the second slider 41, and the suction element 42 are all assembled onto the outer casing 11. It can be understood that in other embodiments, the entire limiting device 40 can be assembled onto the dust collection component 20, or a portion of the limiting device 40 can be assembled onto the outer casing 11, and the remaining portion of the limiting device 40 can be assembled onto the dust collection component 20. Specifically, the dust collection component 20 has a mating groove 22 (see...). Figure 18 When the vacuum cleaner 100 is powered on, the second slider 41 extends into the mating groove 22 to restrict the self-locking device 30 from switching from the self-locking state to the unlocking state.

[0091] It is understood that in some other embodiments, when in the limiting state, the limiting device 40 allows the self-locking device 30 to switch from the self-locking state to the unlocked state. However, even after the limiting device 40 switches to the unlocked state, the dust collection component 20 still cannot detach from the housing 11. That is, at this time, the dust collection component 20 can move forward relative to the housing 11 but cannot move backward. For example, the dust collection component 20 has a second mating part 23. When the vacuum cleaner 100 is powered on, the second slider 41 abuts against the second mating part 23 (see...). Figure 21 and Figure 22 This allows the self-locking device 30 to exit the self-locking state (see...). Figure 22 Switch to unlocked state (see below) Figure 23 and Figure 24 However, it still restricts the dust collection component 20 from being pulled out of the housing 11; when the vacuum cleaner 100 is powered off, the second slider 41 disengages from the second mating part 23, allowing the dust collection component 20 to be pulled out of the housing 11.

[0092] Since the aforementioned limiting device 40 is controlled based on whether the vacuum cleaner 100 is powered on or off, that is, whether the main unit 10 is in working state, there are various ways to determine the working state of the main unit 10, such as detecting the start / stop switch of the main unit 10, detecting the current, voltage, and speed of the pneumatic power device included in the main unit 10, or detecting the airflow and air pressure of the vacuum cleaner 100 to control the limiting device 40 to switch between the limiting state and the release state.

[0093] The disassembly and assembly principle of the dust collection component 20 of the vacuum cleaner 100 provided in this embodiment of the invention is as follows:

[0094] Installation of dust collection component 20:

[0095] The dust collection component 20 first extends into the inner cavity of the outer casing 11 (see...) Figure 15 and Figure 16 At this time, the dust collection component 20 is not installed in the inner cavity, and the hook 313 is limited to the second limiting part 3123. When the dust collection component 20 extends into the inner cavity a certain distance, it abuts against the end face of the first slider 312. Figure 13 and Figure 14 As the dust collector 20 continues to move inward and presses the first slider 312, the hook 313 slides within the first groove 3121, and the first slider 312 slides within the second groove 3111 under the restoring force of the first elastic member 314. Finally, the hook 313 switches from being limited to the second limiting part 3123 to being limited to the first limiting part 3122. At this time, the second elastic member 323 is compressed, the first inclined surface 3124 abuts against the second inclined surface 3221, and the latch 3222 engages with the first mating part 21 of the dust collector 20 to lock the dust collector 20 and the outer casing 11 (see reference). Figure 11 and Figure 12 ).

[0096] Furthermore, when the vacuum cleaner 100 is powered on, the second slider 41 is confined within the limiting groove 22, preventing the dust collection component 20 from detaching from the outer casing 11 (see...). Figure 17 and Figure 18 ).

[0097] Disassembly of dust collection component 20:

[0098] When the vacuum cleaner 100 is powered off, the second slider 41 disengages from the limiting groove 22, and the dust collection component 20 can detach from the outer casing (see...). Figure 19 and Figure 20 ).

[0099] When the dust collector 20 presses down on the first slider 312, the hook 313 slides in the same direction within the second groove 3111, the first elastic element 314 is compressed, and the first slider 312 slides within the second groove 3111. Finally, the hook 313 switches from being limited to the first limiting part 3122 to being limited to the second limiting part 3123. The second elastic element 323 returns to its original deformation, the second inclined surface 3221 abuts against the plane 3124, and the latch 3222 separates from the first mating part 21. At this time, the self-locking element 322 allows the dust collector 20 to separate from the outer casing 11 (see reference). Figure 13 and Figure 14 ).

[0100] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0101] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
