Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaners, and specifically to a one-key cleaning type dust cup for a vacuum cleaner. Background Art

[0002] In the vacuum cleaners on the current market, a filter is installed in the center of the dust cup, and the dust cup is detachably connected to the vacuum cleaner body. The structure of the dust cup is as disclosed in the Chinese patent with the application number CN202010159656.3 and the title of a vacuum cleaner convenient for cotton wool separation. Its structure generally includes a vacuum cleaner body with a motor built therein and a dust cup detachably connected to the vacuum cleaner body. A filter cover and a filter element are arranged in the dust cup. The filter cover includes a first cylinder body provided with filter holes and a second cylinder body coaxially arranged below the first cylinder body. The second cylinder body is used for collecting dust and has a diameter smaller than that of the first cylinder body. A tightening ring is detachably arranged on the inner wall of the dust cup. The tightening ring includes a retaining ring at the periphery and at least two pressing ring blocks at the inner periphery, and a deformation ring arranged between the pressing ring blocks and the retaining ring. The deformation ring drives the pressing ring blocks to move towards the center part, and when the pressing ring blocks are pressed against each other, the diameter of the circle formed by the enclosing of the pressing ring blocks is equal to the outer diameter of the first cylinder body. When the filter cover is installed in the dust cup, the pressing ring blocks of the tightening ring are located at the upper part of the first cylinder body. Through the above structure, when the filter cover is taken out, the cotton wool attached thereto can be automatically cleaned.

[0003] Although the vacuum cleaner disclosed in this invention can, to a certain extent, realize the non-manual scraping and collection of cotton wool and dust on the filter cover during the operation of taking out the dust cup, and improve the filtering effect of the filter cover, however, since this cleaning operation cannot be completed in one go, the dust and hair that are not cleaned and still attached to the filter cover are carried out, resulting in dust emission, etc., which will cause certain pollution to the users, the external environment cleaning and hygiene. If the filter cover is to be cleaned according to this operation, the filter needs to be repeatedly inserted and taken out, which will cause more serious pollution. Moreover, for a filter cover that has not been cleaned for a long time or a cleaning object that is too dirty, resulting in too much cotton wool and hair being scraped off, being compacted into a mass or a ring under the pushing pressure, it is extremely easy to cause the filter to be stuck and unable to be taken out. In addition, for the cleaning of the filter cover and the discharge of the hair and cotton wool at the bottom of the dust cup, the vacuum cleaner needs to be disassembled to a large extent, resulting in the cross-operation of the actual operation of cleaning the object to be vacuumed and the cleaning of the vacuum cleaner, and the cleaning time of the vacuum cleaner accounts for a large proportion, and the user experience is not good.

The one-key cleaning component 8 includes a dust scraping structure 81 sleeved on the separation unit 11, a metal connecting rod 82, a cleaning pull ring 83 slidably connected in a guiding chute 84, and a movable groove 22 with a cutting structure arranged on the side wall of the dust cup 2. The guiding chute 84 is embedded in the movable groove 22. The metal connecting rod 82 is slidably connected in the movable groove 22. The cutting structure includes a slider 224, a hinge 226 fixed to the inner side of the slider 224, and cutting knives 227 hinged to both ends of the hinge 226. A pressing ring 822 corresponding to the slider 224 is arranged at the bottom of the metal connecting rod 82. Through the design of the one-key cleaning component outside the filter cover of the one-key cleaning type dust cup of the present invention, only by repeatedly pulling and releasing the cleaning pull ring, the cotton wool and hair wound on the filter cover can be cleaned without contact, without the troublesome operation of manually scraping after taking out the filter as in the general cleaning method, which is hygienic, time-saving and labor-saving, and the use experience is extremely good. For the filter cover that has not been cleaned for a long time or the cleaning object is too dirty, resulting in too much cotton wool and hair scraped off and being compacted into a mass or ring and hanging on the dust blocking ring and unable to fall to the bottom of the dust cup, just press the cleaning pull ring to the bottom, and the cutting structure can cut and shred the cotton wool and hair in a mass or ring shape and make it slide to the bottom of the dust cup for cleaning. The operation is fast and extremely convenient.

[0044] The bottom of the dust cup 2 is hinged with a dust cup bottom cover 3 and is clamped and limited at the opposite side of the hinge. The front end of the dust cup 2 is provided with a docking structure facing the separation unit 11. A dust suction port 5 is sleeved outside the docking structure. An isolation cavity 4 is arranged inside the dust suction port 5. The upper end of the dust cup 2 is connected to a connection cylinder 61 of the vacuum cleaner housing 6. The upper end of the vacuum cleaner housing 6 is sleeved outside the filtering unit 13. A driving chamber 62 for placing the driving unit 7 is arranged at the bottom of the vacuum cleaner housing 6. A handheld end is also arranged at the bottom of the vacuum cleaner housing 6. A switch button 63 is arranged at the upper end of the handheld end, which can ensure the separation efficiency of dust, cotton wool and hair, and is convenient for actual operation and use.

[0045] An isolation plate is hinged in the isolation cavity 4 through a hinge shaft with a built-in spring. The isolation cavity 4 is provided with abutting raised blocks at corresponding positions on the outer edge of the isolation plate, so that when the vacuum cleaner is in an unused state, the dust cup is isolated from the external environment, avoiding the leakage of dust and cotton wool and polluting the outside world. In the use state under a negative pressure environment, the isolation plate can be opened by negative pressure for dust suction.

[0046] The bottom of the metal connecting rod 82 penetrates downward through the movable slot 22 and the connecting column inside the cleaning pull ring 83 and is limited by a limiting rod 823 horizontally inserted at its bottom. A pressing ring 822 is arranged at the corresponding position of the metal connecting rod 82 between the movable slot 22 and the cleaning pull ring 83. A first return spring 821 is arranged at the corresponding position of the metal connecting rod 82 between the movable slot 22 and the dust scraping structure 81, making the sliding and resetting of the metal connecting rod smoother and facilitating the repeated scraping operation of the filter cover.

[0047] A limiting slot 221 is arranged inside the movable slot 22. A cutting structure is movably connected inside the limiting slot 221. Spring grooves 222 and hinge member grooves 223 are arranged on both sides of the limiting slot 221 from outside to inside in sequence. A second return spring 225 is vertically arranged inside the spring groove 222. The second return spring 225 is fixed between the spring groove 222 and the slider 224. Both ends of the hinge member 226 are slidably connected inside the hinge member groove 223. An arc-shaped groove section corresponding to the cutting knife 227 is arranged inside the limiting slot 221. Through the operation of pressing the cleaning pull ring to the bottom, the pressing ring on the metal connecting rod moves downward, and the pressing ring presses down the cutting structure. Through the abutment at the bottom of the arc-shaped groove section of the limiting slot, the cutting knife turns outward and upward, and cuts the cotton wool and hair in a ring or mass shape at its upper end, so that the ring or mass-shaped cotton wool and hair are cut off and slide to the bottom of the dust cup. When the cleaning pull ring is released, the second return spring drives the slider and the cutting knife to reset, facilitating the repeated and efficient cutting of cotton wool and hair.

[0048] Embodiment 2:

[0049] Please refer to Figure 3, on the basis of the above-mentioned first embodiment, preferably, a clamping member with an inwardly converging top extends upward from the side surface of the dust cup bottom cover 3. A vertical limiting plate 31 and an abutting block vertically fixed to the vertical limiting plate 31 are arranged inside the clamping member. Clamping blocks 21 are arranged on both sides of the outer wall of the dust cup 2 on both sides of the vertical limiting plate 31. The vertical limiting plate is strung between the clamping blocks 21 on both sides. The upper end of the clamping block 21 is abutted and limited downward by the abutting block. An outwardly extending, arc-shaped pressing block 32 is further arranged at the upper end of the clamping member. When the cleaning pull ring is pressed to the bottommost part, the pressing block is pressed and falls off, and the dust cup bottom cover is opened, so that the garbage can be quickly emptied. Then, the dust cup bottom cover is turned upward and buckled on the side wall of the dust cup, and it can be used continuously. The operation is fast and extremely convenient.

[0050] Embodiment Three:

[0051] Please refer to Figure 2 , 6 Figure 8, on the basis of the above-mentioned first embodiment, preferably, the dust scraping structure 81 includes a dust scraping brush bracket 811 sleeved on the separation unit 11, a dust scraping brush 812 fixed to the lower end of the dust scraping brush bracket 811, and a socket member 813 fixed to the outer wall of the dust scraping brush bracket 811. The dust scraping brush 812 is a soft scraping strip or a brush, and its bottom is inwardly converging and inclined. The bottom end of the socket member 813 is sleeved on the top of the metal connecting rod 82, so that the dust scraping brush closely adheres to the filter cover and forms a certain inclination angle with it, and efficiently scrapes cotton wool, hair and dust on its surface.

[0052] There is no overlap between the horizontal projections of the limiting rod 823 and the inner connecting column of the cleaning pull ring 83 and the horizontal projection of the slider 224. There is an overlap between the horizontal projection of the pressing ring 822 and the horizontal projection of the slider 224. The one-key cleaning assembly and the cutting structure are better associated through the pressing ring. The vertical distance between the bottom of the dust scraping brush 812 and the top of the dust blocking ring 121 is equal to the vertical distance between the slider 224 and the pressing ring 822. The bottom of the cutting knife 227 is placed on the upper inclined surface of the dust blocking ring 121, so as to cut the mass-shaped and ring-shaped cotton wool and hair at a suitable position, and make the cotton wool and hair roll along the dust blocking ring and fall to the bottom of the dust blocking ring.

[0053] The working principle of a one-key cleaning type dust cup of a vacuum cleaner in this embodiment includes: when the vacuum cleaner is in use, pressing the switch button 63 can start the driving unit 7, creating a negative pressure environment in the filter 1 and the isolation chamber 4, causing the isolation plate in the isolation chamber 4 to be pushed inward by the external atmosphere and turn open, connecting the isolation chamber 4 and the dust suction port 5. Dust, hair, cotton wool, etc. are sucked into the dust cup 2. Some of the above impurities with high density and relatively small air resistance fall to the bottom of the dust cup 2, while the rest are preliminarily filtered by the filter cover 111, separated by the separation unit 11, and multi-stage filtered by the multi-layer filter unit 13. Coarse particles sink into the dust collection cylinder 12, and fine particles are intercepted and adsorbed by the filter unit 13. Clean air is discharged from the upper end of the vacuum cleaner. After the vacuum cleaner has been used for a period of time, hair, cotton wool and other garbage will wind around the surface of the filter cover 111, resulting in a significant reduction in the filtering and cleaning efficiency. At this time, close the switch button 63. Without opening the dust cup 2, remove the filter cover 11 from the filter 1 for cleaning. Just pull down the cleaning pull ring 83, causing the metal connecting rod 82 to move downward, and then drive the dust scraping brush 812 to move closely against the filter cover 111 downward and form a certain inclination angle with it, scraping the cotton wool, hair and dust on its surface. Release the cleaning pull ring 83, and the metal connecting rod 82 will be driven upward by the first return spring 821 to reset, that is, the first use state (as Figure 6 ), and the cleaning of hair and cotton wool on the filter cover can be repeated multiple times. For the filter cover that has not been cleaned for a long time or the cleaning object is too dirty, resulting in too much cotton wool and hair being scraped off, being compacted into a mass or ring under the pushing pressure and hanging on the dust blocking ring 121 and unable to fall to the bottom of the dust cup 2, just press the cleaning pull ring 83 to the bottom, causing the pressing ring 822 to press down the cutting structure. The cutting knife 227 is pushed outward and upward along the hinge 226 by the abutment at the bottom of the arc section of the limiting groove 221, and cuts the cotton wool and hair in the form of a ring or mass at its upper end, causing the ring-shaped cotton wool and hair to be cut off and the mass-shaped cotton wool and hair to be cut into small pieces and slide to the bottom of the dust cup 2, that is, the second use state (as Figure 8 ). Release the cleaning pull ring 83, causing the metal connecting rod 82 to reset. The second return spring 225 drives the slider 224 and the cutting knife 227 to move upward, and through the abutment and limitation of the arc section of the limiting groove 221, the cutting knife 227 is flipped back to its original position. The filter cover is cleaned repeatedly by pulling down, scraping, releasing and resetting. Pull the cleaning pull ring 83 to the bottommost position, causing the cleaning pull ring 83 to abut against and push down the pressing block 32, and the bottom cover 3 of the dust cup can be opened, removing the cotton wool, hair and garbage accumulated at the bottom of the dust cup 2 from the dust cup 2, realizing rapid garbage dumping. Then flip the bottom cover 32 of the dust cup upward and snap it onto the side wall of the dust cup 2 to continue using.

[0054] In summary, due to the adoption of the above technical solutions, the one-key cleaning type dust cup of a vacuum cleaner in this embodiment has the following beneficial effects compared with the prior art:

[0055] 1. The one-key cleaning dust cup of the present invention, through the design of the one-key cleaning component outside the filter cover, only by repeatedly pulling and releasing the cleaning pull ring, can the cotton wool and hair wound on the filter cover be cleaned without contact. There is no need for the troublesome operation of manually scraping after taking out the filter as in the general cleaning method. It is hygienic, time-saving and labor-saving, and the use experience is extremely good. For the filter cover that has not been cleaned for a long time or the cleaning object is too dirty, resulting in too much cotton wool and hair being scraped off and being compacted into groups and rings by the pushing pressure and hanging on the dust blocking ring and unable to fall to the bottom of the dust cup, just press the cleaning pull ring to the bottom, and the cutting structure can cut and shred the ring-shaped and group-shaped cotton wool and hair, and make it slide to the bottom of the dust cup for cleaning. When the cleaning pull ring is pressed to the bottom, the pressing block is pressed off and the bottom cover of the dust cup is opened, so that the garbage can be quickly emptied. Then, turn the bottom cover of the dust cup upward and snap it on the side wall of the dust cup to continue using. The operation is fast and extremely convenient.

[0056] 2. In the present invention, the one-key cleaning component stably guides and horizontally limits the sliding operation of the cleaning pull ring through the guiding chute, so that the metal connecting rod moves downward, and then drives the dust scraping brush to move downward closely against the filter cover and form a certain inclination angle with it, so as to scrape the cotton wool, hair and dust on its surface. When the cleaning pull ring is released, the metal connecting rod is driven by the first return spring to move upward and reset for repeated cleaning; when the cleaning pull ring is pressed to the bottom, the pressing ring on the metal connecting rod moves downward, and the pressing ring presses the cutting structure. Through the abutment at the bottom of the arc section of the limiting groove, the cutting knife turns outward and upward, and cuts the cotton wool and hair in the form of rings and groups at its upper end, so that the ring-shaped and group-shaped cotton wool and hair are cut off and slide to the bottom of the dust cup. When the cleaning pull ring is released, the second return spring drives the slider and the cutting knife to reset.

[0057] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
