Description

Technical Field

[0001] The present invention relates to the technical field related to cleaning devices, and in particular to a cover locking and unlocking mechanism and a cleaning device. Background Art

[0002] A mite remover, also known as a dust mite cleaner, can vacuum, remove mites, and sterilize textile items like beds, sofas, carpets, and clothing through flapping, vacuuming, and ultraviolet light. Existing mite removers primarily consist of a body, a vacuum motor, and a roller brush mounted within. The bottom of the lower housing features a concave roller brush groove. The roller brush, equipped with a motor, is mounted within the groove and positioned near the suction port. A hollowed-out roller brush cover covers the groove, allowing allergens like dust and mites to pass through the hollowed-out portion of the cover and be absorbed by the roller brush before entering the dust cup.

[0003] After the mite remover has been used many times, the roller brush often needs to be taken out for cleaning or replacement. When removing the roller brush, the roller brush cover needs to be removed from the lower shell of the machine body first. However, since the roller brush cover will come into contact with the cleaned surface when the mite remover is in use, in order to ensure the surface flatness of the working surface of the roller brush cover, the roller brush cover is mostly embedded in the bottom of the lower shell and has no protruding grips. Therefore, when removing the roller brush cover, the roller brush cover is not easy to remove, and there is a problem of difficulty in disassembly. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the roller brush cover of the mite removal device in the prior art is difficult to disassemble, thereby providing a cover locking and unlocking mechanism and cleaning device that is easy to disassemble, simple in structure, and has no redundant components.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0048] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] like Figure 1 、 2 The figure shows a preferred embodiment of the cover locking and unlocking mechanism of the present invention. This cover locking and unlocking mechanism is suitable for cleaning devices such as mite removers and vacuum cleaners. When the cover (roller brush cover) needs to be removed, the cover can be lifted upward so that the working surface of the cover is no longer flush with the working surface of the shell. At this time, a portion of the cover protrudes from the shell, making it easier for the user to grasp the cover, allowing the cover to be removed quickly and easily, and providing a good user experience.

[0050] The cover locking and unlocking mechanism is provided on the housing 1 and the cover 2. Through the cover locking and unlocking mechanism, the cover 2 can be locked (fastened) on the housing 1, and can also be lifted and removed from the housing 1. A lock slot 3 is provided on the housing 1, and a lock 4 is provided in the lock slot 3. The lock 4 can move in the lock slot 3. An elastic element is provided between the end of the lock 4 away from the cover 2 and the lock slot 3. In this embodiment, the lock 4 is a semi-closed box structure, and an elastic element mounting column 407 is provided in the interior thereof at a position away from the cover 2. Specifically, in this embodiment, the elastic element is preferably a spring 9, which is sleeved on the elastic element mounting column 407. One end of the spring 9 abuts against the inner wall of the lock slot 3, and the other end abuts against the lock 4. The moving direction of the lock 4 in the lock slot 3 is the extension and contraction direction of the spring 9.

[0051] The lid locking and unlocking mechanism includes a locking structure and an unlocking and lifting structure provided on the lid 2 and the lock catch 4. Through the locking and unlocking and lifting structures, the lid 2 has a locked position and an unlocked position on the housing 1. It should be noted that the locked position means that the lid 2 is fully engaged with the housing 1, at which point the working surface of the lid 2 (i.e., the surface in contact with the object to be cleaned) is flush with the working surface of the housing 1 (i.e., the surface in contact with the object to be cleaned). The unlocked position means that after the lid 2 is lifted, a portion of the lid 2 protrudes from the working surface of the housing 1, but the lid 2 has not yet been removed from the housing 1.

[0052] Furthermore, to ensure structural balance and symmetry and to balance the forces on the cover 2, two sets of locking slots 3 and locking latches 4 are provided at intervals, and correspondingly, two sets of locking structures and unlocking and lifting structures are also provided at intervals. Preferably, both sets of locking structures and both sets of unlocking and lifting structures are symmetrically arranged relative to the centerline of the housing 1 and the cover 2.

[0053] Further, such as Figure 7 As shown, in order to firmly set the lock catch 4 in the lock catch groove 3 and prevent the lock catch 4 from falling out of the lock catch groove 3, the lock catch groove 3 is detachably connected to the lock catch cover plate 7. A first bolt column 304 is provided on one side of the lock catch groove 3, and a second bolt column 703 is provided at a corresponding position of the lock catch cover plate 7. The lock catch cover plate 7 and the lock catch groove 3 are connected by fasteners. Specifically, the fastener is a bolt 8. The second bolt column 703 and the first bolt column 304 are both formed with threaded holes that match the bolt 8. The bolt 8 can be screwed into the threaded holes of the second bolt column 703 and the first bolt column 304, thereby connecting the lock catch cover plate 7 and the lock catch groove 3 together. Furthermore, a connecting groove 702 is provided on one side of the lock catch cover plate 7. Accordingly, the outer wall of the lock catch groove 3 is provided with a connecting block 302 that matches the connecting groove 702. When installing the lock cover plate 7, the connecting block 302 can be inserted into the connecting groove 702 first to pre-install the lock cover plate 7 to ensure that the bolt 8 can be more accurately and quickly inserted into the threads of the second bolt column 703 and the first bolt column 304 for connection and assembly.

[0054] like Figure 3-6 As shown, the end of the lock catch 4 away from the spring 9 is provided with a protrusion 401. The protrusion 401 extends out of the lock catch 4 and extends in a direction parallel to the movement direction of the lock catch 4. The portion of the protrusion 401 away from the lock catch 4 has a triangular cross-section parallel to the movement direction of the lock catch 4, and has a certain width in a direction perpendicular to the movement direction of the lock catch 4. Correspondingly, the cover body 2 is provided with a top portion 201. The top portion 201 protrudes from the inner surface of the cover body 2 and has a triangular cross-section parallel to the movement direction of the lock catch 4.

[0055] The unlocking and lifting structure includes a protrusion 401 and a lifting portion 201. The protrusion 401 has a first lifting slope 402, which slopes from the protrusion 401 toward the cover 2. Correspondingly, the lifting portion 201 has a second lifting slope 202, which slopes from the lifting portion 201 toward the lock buckle 4. During the unlocking process, the first lifting slope 402 and the second lifting slope 202 can contact each other and move relative to each other along their interface. When the contact area between the first lifting slope 402 and the second lifting slope 202 decreases, the lock buckle 4 lifts the cover 2.

[0056] Furthermore, the end of the raised portion 401 facing the cover body 2 has a card slot 403, and the card slot 403 extends along the width direction of the raised portion 401 (that is, perpendicular to the moving direction of the lock buckle 4). When the cover body 2 is in the unlocked position, the end of the top portion 201 facing the lock buckle 4 is placed in the card slot 403 to keep the cover body 2 in the unlocked position, making it convenient for the user to grab the cover body 2 and making it easier to disassemble the cover body 2.

[0057] Furthermore, a locking tongue 404 is provided at the end of the lock catch 4 away from the spring 9. In this embodiment, two protrusions 401 are provided, and the locking tongue 404 is disposed between the two protrusions 401, that is, the two protrusions 401 are disposed on either side of the locking tongue 404. The cross-section of the locking tongue 404 parallel to the direction of movement of the lock catch 4 is similar to a triangle, and the locking tongue 404 has a certain width in a direction perpendicular to the direction of movement of the lock catch 4. Correspondingly, a locking groove 203 is also provided on the cover body 2, which protrudes from the inner surface of the cover body 2. In this embodiment, two protrusions 201 are also provided, and the locking groove 203 is disposed between the two protrusions 201, that is, the two protrusions 201 are disposed on either side of the locking groove 203. In this embodiment, the protrusion 201 and the locking groove 203 are disposed on the first mating side 205 of the cover body 2, which is one of the long sides of the cover body 2.

[0058] The locking structure includes a locking tongue 404 and a locking groove 203. When the locking tongue 404 is inserted into the locking groove 203, the cover body 2 is in a locked position.

[0059] Furthermore, the lock tongue 404 has a first locking bevel 405, and the outer wall of the locking groove 203 has a second locking bevel 204. When the cover body 2 moves from the unlocked position to the locked position, the first locking bevel 405 contacts the second locking bevel 204 and can move relative to each other along the interface between the two. When the contact area between the first locking bevel 405 and the second locking bevel 204 is reduced to the point where the two are disengaged, the lock tongue 404 is inserted into the locking groove 203 to achieve locking of the cover body 2.

[0060] Furthermore, the cover locking and unlocking mechanism of this embodiment also includes a limiting structure for restricting translation of the cover 2 on the housing 1. The limiting structure includes at least two mutually cooperating limiting buckles 5 and at least two limiting slots 6. The limiting buckles 5 are provided on one of the housing 1 and the cover 2, while the limiting slots 6 are provided on the other. When the limiting buckles 5 are inserted into the limiting slots 6, the cover 2 cannot translate on the housing 1 and can only rotate.

[0061] In this embodiment, the retaining buckle 5 is positioned on the second mating side 206 of the cover 2. The second mating side 206 is one of the long sides of the cover 2, and the first mating side 205 and the second mating side 206 are positioned opposite each other. In this embodiment, four retaining buckles 5 are provided, spaced apart along the length of the second mating side 206. Four retaining slots 6 are provided on the housing 1, corresponding to the positions of the retaining buckles 5. When the retaining buckles 5 are inserted into the retaining slots 6, the cover 2 cannot translate on the housing 1 and can only rotate about its second mating side 206.

[0062] Furthermore, the lock catch 4 has a toggle portion 406 that is exposed from the housing 1. Specifically, the bottom of the lock catch slot 3 has a through hole 303, and the toggle portion 406 protrudes from the surface of the lock catch 4. The toggle portion 406 enters the through hole 303, but in order to ensure that the working surface of the cover 2 is flush with the working surface of the housing 1, when the cover 2 is locked (fastened) to the housing 1, the toggle portion 406 does not protrude from the working surface of the housing 1.

[0063] Furthermore, the lock catch 4 can move in the lock catch slot 3 along the expansion and contraction direction of the spring 9. To limit the movement distance of the lock catch 4, a first limiting portion 301 is provided on the inner wall of the lock catch slot 3 away from the cover body 2, and a second limiting portion 701 is provided on the side of the lock catch cover 7 facing the lock catch 4. The first limiting portion 301 and the second limiting portion 701 can limit the movement distance of the lock catch 4 in the lock catch slot 3. In other words, when the lock catch 4 moves and abuts the first limiting portion 301, the lock catch 4 cannot move further and the spring 9 cannot be compressed further. When the lock catch 4 moves and abuts the second limiting portion 701, the lock catch 4 cannot move further and the spring 9 cannot be extended further.

[0064] In order to further understand the cover locking and unlocking mechanism of this embodiment, Figure 8-14 , the unlocking process and locking process of the cover locking and unlocking mechanism of this embodiment are described in detail:

[0065] like Figure 8 As shown, when the cover body 2 is in the locked position, the lock tongue 404 is engaged in the locking groove 203, and the toggle portion 406 is placed in the middle position of the through hole 303. If the toggle portion 406 is toggled away from the cover body 2, the lock buckle 4 can move away from the cover body 2.

[0066] like Figure 9 As shown, when the cover 2 needs to be removed, the toggle portion 406 is toggled in the direction of the arrow (rightward in the figure) to drive the lock catch 4 to move away from the cover 2. During this process, the spring 9 is continuously compressed until the lock tongue 404 is released from the locking groove 203. Figure 10 As shown, at this time, the first lifting inclined surface 402 contacts the second lifting inclined surface 202, and the toggle portion 406 continues to be toggled in the direction of the arrow (rightward in the figure); Figure 11 As shown, the contact area between the first lifting bevel 402 and the second lifting bevel 202 gradually decreases, and the cover body 2 is then lifted upward. The cover body 2 rotates in the direction of the rotation arrow (counterclockwise in the figure) to a certain extent, so that a part of the cover body 2 protrudes from the working surface of the shell 1; then, as shown in FIG. Figure 12 As shown, continue to push the toggle portion 406 in the direction of the arrow (rightward in the figure) until the end of the lifting portion 201 facing the lock buckle 4 is placed in the card slot 403. At this time, the cover body 2 is completely lifted up, and the cover body 2 is in the unlocked position and remains in the unlocked position. In order to make the structure more reliable, the lock buckle 4 also presses against the first limit portion 301, and the spring 9 can no longer be compressed. At this time, the user can grab the lifted part of the cover body 2 and remove the cover body 2. The disassembly process of the cover body 2 is now completed. After the cover body 2 is removed, as shown in FIG. Figure 13 As shown, under the action of the restoring force of the spring 9 , the lock catch 4 moves in the direction of the arrow (leftward in the figure) until the lock catch 4 abuts against the second limiting portion 701 .

[0067] like Figure 14 As shown, when the cover body 2 needs to be installed, the limit buckle 5 is first inserted into the limit groove 6. At this time, the cover body 2 can only be rotated around the direction of the rotation arrow in the figure (clockwise in the figure) to approach the shell 1. As the second locking bevel 204 contacts the first locking bevel 405, the two move relative to each other along the interface. Continue to press the cover body 2 downward, and the cover body 2 pushes the lock buckle 4 to move along the direction of the straight arrow (to the right in the figure). The spring 9 is compressed until the lock tongue 404 is stuck in the locking groove 203. At this point, the cover body 2 is installed.

[0068] This embodiment further provides a cleaning device, including the cover locking and unlocking mechanism provided in this embodiment. When the cover locking and unlocking mechanism is applied to the cleaning device, the housing 1 of the cover locking and unlocking mechanism becomes the lower housing of the cleaning device, and the cover 2 of the cover locking and unlocking mechanism becomes the roller brush cover of the cleaning device. In this embodiment, the cleaning device is a mite remover. By providing the cover locking and unlocking mechanism, during the process of removing the roller brush cover, the unlocking and lifting structure can lift the roller brush cover upward, so that the working surface of the roller brush cover is no longer flush with the working surface of the lower housing. At this time, a portion of the roller brush cover protrudes from the lower housing, making it easier for the user to grasp the roller brush cover, allowing the roller brush cover to be quickly and easily removed, and providing a good user experience.

[0069] It should be noted that when removing the roller brush cover of the mite remover, in order to facilitate operation, the mite remover is usually turned 180 degrees as a whole, that is, the roller brush cover is on top, the lower shell is at the bottom, and the toggle part 406 is facing upwards, so that it is convenient to move the locks 4 on both sides with both hands to unlock the roller brush cover.

[0070] In other embodiments, the limiting buckle 5 can also be provided on the shell 1 , and the limiting groove 6 can be provided on the cover 2 , which can also achieve the purpose of limiting the translation of the cover 2 on the shell 1 .

[0071] In other embodiments, the number of the limiting buckles 5 in the limiting structure can also be two, three, five, etc., and correspondingly, the number of the limiting slots 6 can also be two, three, five, etc., and the present invention does not impose any limitation on this.

[0072] In other embodiments, the cleaning device may also be a vacuum cleaner.

[0073] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
