Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, and more particularly to a wireless handheld vacuum cleaner. Background Art

[0002] A car vacuum cleaner is a device specifically used to clean dust and debris inside a car. With the popularization of cars, people pay more and more attention to cleaning inside the car, and the demand for car vacuum cleaners is also increasing.

[0003] Currently, there are many types of car vacuum cleaners on the market, mainly including wired and wireless types. Wired car vacuum cleaners usually need to be connected to the vehicle's cigarette lighter or USB port, which is inconvenient to use. Cordless car vacuum cleaners, on the other hand, are free from the constraints of power cords and can be used anytime, anywhere with just enough battery power. They are more flexible and convenient to use, and are not restricted by the location of use. Therefore, they are gradually gaining popularity.

[0004] However, the common cordless car vacuum cleaners on the market still have many defects, such as: ① Most cordless car vacuum cleaners use HEPA filter elements in their filtration systems. Although HEPA filter elements can effectively filter out dust and other impurities, they are mostly unable to be cleaned due to the limitations of their materials and can only be replaced regularly, which is not only troublesome, but also will seriously affect the dust removal effect if not replaced in time; ② Dust, stains and garbage in some places in the car have strong adhesion, and they cannot be sucked away and removed by suction alone, resulting in poor cleaning effect; ③ Most cordless car vacuum cleaners are of integrated structure, and the various parts cannot be disassembled. On the one hand, it is not convenient for cleaning and storage, and on the other hand, it is impossible to regularly repair and replace parts, which affects the service life; ④ The function is single. Most cordless car vacuum cleaners only have the function of vacuuming and cannot meet the user's more needs. Utility Model Content

The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0058] Example 1

[0059] This embodiment is an embodiment of a wireless handheld vacuum cleaner. Figure 1 and Figure 2 As shown, the main housing 1 comprises a fan assembly 2, a cyclonic dust removal device 3, and an air blowing nozzle 4. In this embodiment, the main housing 1 is a cylindrical structure with openings at both ends, respectively forming an air inlet and an air outlet. The fan assembly 2 is disposed within the main housing 1, with the air intake end of the fan assembly 2 corresponding to the air inlet of the main housing 1, and the air outlet end of the fan assembly 2 corresponding to the air outlet of the main housing 1.

[0060] In this embodiment, the fan assembly 2 is used to generate suction and pressure. Under the action of suction and pressure, air is discharged from the air outlet of the main shell 1, causing negative pressure to be generated inside the main shell 1, so that air carrying impurities such as dust can be sucked into the cyclone separation and dust removal device 3 for dust removal. The air that has undergone dust removal enters from the air inlet of the main shell 1 and is discharged from the air outlet of the main shell 1 through the fan assembly 2.

[0061] Specifically, in this embodiment, the fan assembly 2 includes a motor and turbine blades coaxially and tightly fitted on the motor shaft, wherein the motor can be a brushless DC motor to increase suction, reduce noise, and improve user experience.

[0062] In this embodiment, the cyclone dust removal device 3 is detachably mounted at the air inlet of the main housing 1, and the air blowing nozzle 4 is detachably mounted at the air outlet of the main housing 1. By selectively detaching and assembling the cyclone dust removal device 3 and the air blowing nozzle 4, the utility model can be used as a vacuum cleaner for cleaning inside a car, or for household use, such as cleaning sofas, tabletops, furniture corners, window frames, etc., and can also be used as an air pump, thereby meeting the various needs of users.

[0063] Specifically, when the cyclone separation dust removal device 3 is installed at the air inlet of the main shell 1 and the blowing nozzle 4 is removed from the air outlet of the main shell 1, the utility model can be used as a vacuum cleaner, that is, under the driving action of the fan assembly 2, the dust, debris, garbage, etc. to be cleaned can be sucked in along with the air through the cyclone separation dust removal device 3 and filtered and dust removed. Then the gas can enter through the air inlet of the main shell 1 and be discharged from the air outlet of the main shell 1 through the fan assembly 2.

[0064] When the air blowing nozzle 4 is installed at the air outlet of the main shell 1 and the cyclone separation dust removal device 3 is removed from the air inlet of the main shell 1, the utility model can be used as an air pump to inflate items that need to be inflated, such as inflatable mattresses and swimming rings.

[0065] like Figure 3 As shown, the cyclone dust removal device 3 in this embodiment includes a dust bin 31, a cyclone separator 5, and a suction cylinder assembly 6. In this embodiment, the dust bin 31 is a cylindrical structure with openings at both ends. The top opening of the dust bin 31 is detachably connected to the air inlet of the main housing 1, and the bottom opening of the dust bin 31 is provided with a retractable bottom cover 32. Specifically, in this embodiment, the bottom cover 32 is hinged to the bottom end of the dust bin 31 and can be flipped open or closed to cover the bottom of the dust bin 31.

[0066] like Figure 1 and Figure 4 As shown, when the bottom cover 32 is closed to the bottom end of the dust bin 31, it is locked by the cover opening switch 33. When the present invention is used as a vacuum cleaner, the cover opening switch 33 can be used to lock the bottom cover 32 to the bottom end of the dust bin 31 to prevent dust, debris and other garbage in the dust bin 31 from leaking out. When it is necessary to clean the dust, debris and other garbage in the cyclone dust removal device 3, the cover opening switch 33 can be pressed to flip the bottom cover 32 away from the dust bin 31.

[0067] Specifically, in this embodiment, the cover opening switch 33 includes a cover opening member 331 and a first elastic member 332. A first mounting frame 312 is fixedly provided on the side wall of the dust bin 31, and the cover opening member 331 is rotatably mounted within the first mounting frame 312. Specifically, circular mounting recesses are provided on the two opposing side walls of the first mounting frame 312, and cylindrical mounting protrusions are provided on the two opposing side walls in the middle of the cover opening switch 331. The mounting protrusions are movably inserted into the mounting recesses. The mounting recesses and the mounting protrusions can constrain the cover opening member 331 within the first mounting frame 312, and pressing one end of the cover opening member 331 causes the other end of the cover opening member 331 to rotate in the opposite direction.

[0068] The lower end of the cover opening member 331 is provided with a snap-on protrusion 334 on the side facing the dust bin 31. An extension block 321 is provided outwardly from the edge of the bottom cover 32. A docking block 322 is perpendicularly provided on the extension block 321. The docking block 322 is provided with a snap-on groove 323 that can snap-on with the snap-on protrusion 334. The upper end of the cover opening member 331 abuts against a first elastic member 332. In this embodiment, the first elastic member 332 is a spring. One end of the first elastic member 332 is connected to the upper side wall of the cover opening member 331, and the other end is connected to the side wall of the dust bin 31.

[0069] When the bottom cover 32 needs to be opened, the upper end of the cover-opening member 331 is pressed, compressing the first elastic member 332. The engaging protrusion 334 at the lower end of the cover-opening member 331 moves away from the engaging groove 323. At this point, the engaging protrusion 334 and the engaging groove 323 are disengaged, and the bottom cover 32 can be opened from the bottom end of the dust bin 31. When the pressure on the cover-opening member 331 is released, the first elastic member 332 allows the cover-opening member 331 to return to its original position. Therefore, when the bottom cover 32 is closed onto the bottom end of the dust bin 31, the engaging protrusion 334 can be securely engaged with the engaging groove 323 under the action of the first elastic member 332, allowing the bottom cover 32 to be securely closed onto the bottom end of the dust bin 31.

[0070] The extension block 321 can provide a position for the user to exert force, thereby facilitating the user to easily open the bottom cover 32. As a preferred technical solution, in this embodiment, a raised ring 324 is provided on the bottom cover 32. When the bottom cover 32 is closed to the bottom end of the dust bin 31, the raised ring 324 is inserted into the dust bin 31. In this embodiment, a first sealing ring 325 is provided on the outer wall of the raised ring 324 or the bottom end of the dust bin 31. In another embodiment, the outer wall of the raised ring 324 and the bottom end of the dust bin 31 are both provided with the first sealing ring 325. The provision of the first sealing ring 325 can further improve the sealing between the bottom cover 32 and the dust bin 31, effectively locking dust within the dust bin 31 and reducing dust leakage.

[0071] like Figure 1 and Figure 3As shown, a dust inlet 311 is provided on the side wall of the dust bin 31, and the suction cup assembly 6 is connected to the dust inlet 311 via a connector 7. As a preferred technical solution, in this embodiment, the suction cup assembly 6 and the connector 7 are detachably connected, and the connector 7 and the dust bin 31 are detachably connected. This arrangement not only facilitates the replacement of suction cup assemblies 6 of different shapes to meet different scenarios and needs, but also allows each component to be disassembled for easy cleaning, maintenance, replacement, storage, and transportation.

[0072] Specifically, such as Figure 5 As shown, in this embodiment, one end of the connector 7 is detachably connected to the side wall of the dust bin 31 by pressing the buckle structure 72. Specifically, in this embodiment, a second mounting frame 314 is fixedly provided on the side wall at the dust inlet 311 of the dust bin 31, and the connector 7 is snapped onto the second mounting frame 314 by pressing the buckle structure 72.

[0073] In this embodiment, the connector 7 includes a main body 711 and an assembly portion 712. The assembly portion 712 is detachably connected to the side of the main body 711 facing the dust inlet 311. In this embodiment, the main body 711 and the assembly portion 712 are detachably connected via screws or rivets. It should be noted that the use of screws or rivets in this embodiment is a preferred method for achieving a detachable connection between the main body 711 and the assembly portion 712 and is not intended to limit the present invention.

[0074] In this embodiment, the pressing and snapping structure 72 includes a pressing member 721 and a second elastic member 722. The pressing member 721 is movably arranged on the assembly portion 712. The pressing member 721 includes a pressing portion 7211 and a snapping portion 7212 connected to each other. The main body 711 is provided with an opening for the pressing portion 7211 to extend out. The pressing portion 7211 extends from the opening on the main body 711 to facilitate the user to perform a pressing operation. The side wall of the second mounting frame 314 is provided with a first snap-fitting limit block 315 that can be snap-fitted with the snapping portion 7212 to limit the position. In this embodiment, the second elastic member 722 is a spring and is arranged inside the main body 711. Specifically, one end of the second elastic member 722 abuts against the pressing portion 7211, and the other end abuts against the main body 711.

[0075] Pressing the pressing member 721 causes it to move in the pressing direction and compress the second elastic member 722. At this point, the snap portion 7212 moves away from the first locking stop block 315, effectively releasing the locking stop block 315 from the locking stop block 315, and the connector 7 can be removed from the second mounting frame 314. By releasing the pressing member 721, the pressing member 721 returns to its original position under the action of the second elastic member 722. When the connector 7 is mounted on the second mounting frame 314, the snap portion 7212 securely engages with the first locking stop block 315 under the action of the second elastic member 722, securing the connector 7 securely to the second mounting frame 314.

[0076] To facilitate user operation, in this embodiment, a press-lock structure 72 is provided at the top of the connector 7. To further enhance the secure installation of the connector 7 on the second mounting frame 314, a snap member 73 is provided at the bottom of the main body 711, and a second snap-locking stopper 316 is provided on the sidewall of the second mounting frame 314. When the connector 7 is mounted on the second mounting frame 314, the snap member 73 snaps onto the second snap-locking stopper 316. In this embodiment, the snap-locking surfaces 731 where the snap member 73 and the second snap-locking stopper 316 contact each other are both inclined. This arrangement facilitates quick engagement and disengagement of the snap member 73 with the second snap-locking stopper 316. In this embodiment, the connector 7 is securely connected to the dust bin 31 via the press-lock structure 72 and the snap member 73.

[0077] like Figure 5 As shown, the other end of the connecting head 7 of this embodiment is provided with a mounting groove 74 for mounting with the suction tube assembly 6. In this embodiment, the suction tube assembly 6 includes a suction tube 61, which is inserted into the mounting groove 74. The shape of the suction nozzle of the suction tube 61 can be selected and designed according to actual needs.

[0078] In this embodiment, the connector 7 is provided with a connecting passage 713 communicating with the suction cylinder assembly 6 and the dust inlet 311. Since the user may place the dust inlet 311 of the dust bin 31 toward the ground during use, dust, debris, and other garbage in the dust bin 31 may leak out of the dust inlet 311 due to gravity. In order to prevent dust, debris, and other garbage in the dust bin 31 from leaking out of the dust inlet 311, a baffle 75 is rotatably provided in the connecting passage 713 of the connector 7 in this embodiment.

[0079] like Figure 5As shown, in this embodiment, the baffle 75 is rotatably connected to the connecting channel 713 of the connecting head 7. When the utility model is working as a vacuum cleaner, the baffle 75 rotates with the inward suction force, so that the baffle 75 is in the first position. At this time, the connecting channel 713 is connected to the dust inlet 311, and the dust bin 31 can normally suck in external dust, debris and other garbage; when the utility model is not working as a vacuum cleaner, the baffle 75 can rotate to the second position under the action of its own gravity. At this time, the baffle 75 can block the connecting channel 713 to prevent dust, debris and other garbage in the dust bin 31 from leaking out of the dust bin 31 when the dust inlet 311 is perpendicular to the ground, thereby improving the sealing of the dust bin 31 and thus enhancing the user experience.

[0080] As a preferred technical solution, Figure 6 As shown, the dust inlet 311 of this embodiment is square, and an abutment portion 3111 is provided on the outer wall of the dust bin 31 on the side of the dust inlet 311. The abutment portion 3111 is arranged at an angle. When the vacuum cleaner is in operation, the baffle 75 rotates in response to the inward suction force, and the baffle 75 abuts against the abutment portion 3111. At this time, the baffle 75 can guide the airflow, so that the airflow entering the suction cylinder assembly 6 moves to the dust inlet 311 under the guidance of the baffle 75.

[0081] like Figure 7 As shown, a guide portion 3112 is provided on the inner sidewall of the dust bin 31 on the other side of the dust inlet 311. The arrangement of the guide portion 3112 allows the airflow entering the dust inlet 311 to enter the dust bin 31 along a tangential direction of the inner sidewall of the dust bin 31. In this embodiment, the arrangement of the abutment portion 3111 and the guide portion 3112 can effectively adjust the flow direction of the airflow, allowing the air to enter the dust bin 31 along a tangential direction, thereby increasing the length of the air duct for the airflow rotation and improving the cyclonic separation effect.

[0082] like Figure 3 As shown, in this embodiment, the cyclone separator 5 is arranged inside the dust bin 31, and the air outlet end of the cyclone separator 5 is connected to the air inlet of the main shell 1. In this embodiment, the central axis of the cyclone separator 5 is coaxially arranged with the central axis of the fan assembly 2, so that the direction of the air duct in the main shell 1 is basically consistent with the air outlet direction of the cyclone separator 5. The suction force generated by the fan assembly 2 can directly suck out the airflow in the cyclone separator 5, ensuring the suction force of the vacuum cleaner, which is beneficial to improving the dust separation and removal effect and cleaning efficiency.

[0083] Specifically, such as Figure 3As shown, the cyclone separator 5 in this embodiment includes an outer cylinder 51, a mounting base 52, a cyclone separation cylinder 53, and a filter element 8. The outer cylinder 51 is disposed inside the dust bin 31, the cyclone separation cylinder 53 is disposed within the outer cylinder 51, the mounting base 52 is disposed at the air outlet end of the cyclone separation cylinder 53, and the mounting base 52 is detachably connected to the outer cylinder 51. The filter element 8 is detachably mounted on the mounting base 52.

[0084] like Figure 8 As shown, in this embodiment, filter holes 511 are evenly distributed on the side walls of the outer cylinder 51 at a height position corresponding to the dust inlet 311 of the dust bin 31. The filter holes 511 can perform a first-level filtration on large particles of impurities sucked into the dust bin 31. Large particles of debris and other garbage that cannot pass through the filter holes 511 are trapped in the dust bin 31. Dust, small particles of debris and other garbage that can pass through the filter holes 511 enter the cyclone separation cylinder 53 together with the air for cyclone separation and dust removal.

[0085] As a preferred technical solution, in this embodiment, a buffer eave 512 is provided on the outer cylinder 51. The buffer eave 512 is located below the filter holes 511 provided on the outer cylinder 51. The provision of the buffer eave 512 in this embodiment can buffer and guide larger debris that cannot pass through the filter holes 511, thereby reducing the impact of large particles of debris on the dust bin 31 and the bottom cover 32. At the same time, the buffer eave 512 can also provide a certain buffering effect on the airflow, increasing the residence time of the airflow at the filter holes 511, thereby improving the effectiveness of the primary filtration.

[0086] In this embodiment, the outer cylinder 51 is detachably connected to the top of the dust bin 31. Figure 6-Figure 8 As shown, in this embodiment, a first abutting step 317 is provided on the inner side of the top of the dust bin 31, and the top of the outer cylinder 51 extends horizontally outward to form a overlapping flange 513. When the cyclone separator 5 is placed in the dust bin 31, the overlapping flange 513 of the outer cylinder 51 overlaps the first abutting step 317 of the dust bin 31.

[0087] In this embodiment, a connecting ring 514 is vertically fixed to the top of the overlapping flange 513. The connecting ring 514 is coaxial with the outer cylinder 51. A limiting protrusion 515 is provided on the outer wall of the connecting ring 514. In this embodiment, two limiting protrusions 515 are provided, and the two limiting protrusions 515 are oppositely disposed on the outer wall of the connecting ring 514. A limiting groove 318 capable of plugging into the limiting protrusion 515 is provided on the inner wall of the first abutting step 317 of the dust bin 31. Correspondingly, two limiting grooves 318 are also provided, and the two limiting grooves 318 are respectively oppositely disposed on the inner wall of the first abutting step 317. When the outer cylinder 51 is installed in the dust bin 31, the overlapping flange 513 of the outer cylinder 51 overlaps the first abutting step 317 of the dust bin 31, and the limiting protrusion 515 is inserted into the limiting groove 318. In this embodiment, the setting of the limiting protrusion 515 and the limiting groove 318 can limit the circumferential rotation of the outer cylinder 51 in the dust bin 31, thereby improving the stability of the outer cylinder 51 installed in the dust bin 31, and also plays a role in installation positioning.

[0088] As a preferred technical solution, Figure 9 As shown, in this embodiment, a second sealing ring 319 is provided between the side wall of the connecting ring 514 and the first abutting step 317. The setting of the second sealing ring 319 can improve the sealing of the assembly between the outer cylinder 51 and the dust bin 31, which is beneficial to ensure the negative pressure environment inside the main shell, so that the vacuum cleaner has sufficient suction force, which can greatly improve the separation and dust removal effect of the vacuum cleaner.

[0089] like Figure 10 and Figure 11 As shown, the cyclone separator 53 of this embodiment is composed of several hollow conical members 531 with adjacent sides. The upper end of each conical member 531 is larger than the lower end. As a preferred technical solution, the number of conical members 531 is 4-8. In this embodiment, six conical members 531 are provided. This is the preferred number of conical members 531 for the cyclone separator 53 of this utility model. While ensuring effective dust removal, the entire vacuum cleaner can be made compact and lightweight.

[0090] As a preferred technical solution, an air guide groove 532 is provided on the outer side of the upper end of the conical member 531 in this embodiment. One end of the air guide groove 532 communicates with the interior of the conical member 531, while the other end is open. In this embodiment, the air guide groove 532 has a rectangular cross-section. The air guide groove 532 guides the inhaled airflow, ensuring that the rotation direction of the centrifugal cyclone generated by each conical member 531 follows a predetermined direction. This enhances the centrifugal force generated by the cyclone separation barrel 53, thereby improving the centrifugal separation effect of the cyclone separator 5.

[0091] like Figure 12As shown, the cyclone separation cylinder 53 of this embodiment is limitedly installed inside the outer cylinder 51. Specifically, in this embodiment, the bottom of the cyclone separation cylinder 53 is provided with an abutment plate 533, and the lower part of the outer cylinder 51 is provided with a second abutment step 516. When the cyclone separation cylinder 53 is installed in the outer cylinder 51, the abutment plate 533 of the cyclone separation cylinder 53 can abut against the second abutment step 516 on the outer cylinder 51.

[0092] As a preferred technical solution, in this embodiment, the bottom edge of the abutment plate 533 extends downward to form a limiting ring 534, and a limiting ring groove 517 is provided on the second abutment step 516. When the abutment plate 533 abuts against the second abutment step 516 on the outer cylinder 51, the limiting ring 534 can be inserted into the limiting ring groove 517. The arrangement of the limiting ring 534 and the limiting ring groove 517 can further improve the stability of the cyclone separation cylinder 53 installed in the outer cylinder 51.

[0093] like Figure 9 and Figure 10 As shown, the mounting base 52 is provided at the air outlet end of the cyclone separation barrel 53 and is detachably mounted on the top end of the outer barrel 51. Specifically, the mounting base 52 includes a base 521. In this embodiment, a placement groove 522 is provided at the top. The edge of the placement groove 522 extends horizontally outward to form a connecting edge 523. In this embodiment, the connecting edge 523 is connected to the top end of the outer barrel 51 via screws or rivets. It should be noted that the use of screws or rivets in this embodiment is a preferred method for achieving a detachable connection between the mounting base 52 and the outer barrel 51 and is not intended to be a limitation of the present invention.

[0094] In this embodiment, the cyclone separation cylinder 53 is detachably connected to the mounting base 52. Specifically, Figure 11 and Figure 13 As shown, a plug-in column 524 is provided on the bottom of the seat body 521 of the mounting seat 52, and a plug-in groove 535 is provided on the top of the cyclone separation cylinder 53 for plugging the plug-in column 524.

[0095] As a preferred technical solution, in this embodiment, the side wall of the plug-in column 524 is fixedly provided with a limit bar 525 along the axial direction of the plug-in column 524, and the side wall of the plug-in groove 533 is provided with a limit groove 536. When the plug-in column 524 is plugged into the plug-in groove 535, the limit bar 525 is located in the limit groove 536. The setting of the limit bar 525 and the limit groove 536 can limit the rotation of the cyclone separation cylinder 53 on the mounting seat 52, thereby improving the stability of the assembly of the cyclone separation cylinder 53 and the mounting seat 52.

[0096] like Figure 3 and Figure 13As shown, in this embodiment, the bottom of the mounting base 52 is further provided with a plurality of air outlets 526. The number of air outlets 526 is the same as the number of conical members 531 of the cyclone separator 53. When the cyclone separator 53 and the mounting base 52 are assembled together, the air outlets 526 on the mounting base 52 extend into the conical members 531 on the cyclone separator 53 in a one-to-one correspondence, and the air outlets 526 and the conical members 531 are arranged coaxially. One end of the air outlet 526 extends into the interior of the conical member 531 and communicates with the interior of the conical member 531. The other end of the air outlet 526 is connected to the air inlet of the main housing 1. The gas after dust removal by the cyclone separator 53 enters the main housing 1 through the air outlet 526. The provision of the air outlet 526 helps guide the airflow and ensure smooth gas discharge.

[0097] As a preferred technical solution, Figure 9 As shown, a first sealing gasket 54 is further provided at the contact position between the mounting seat 52 and the cyclone separation barrel 53 of this embodiment. The first sealing gasket 54 is provided with a through hole for the conical part 531, the plug-in column 524 and the limit strip 525 to pass through. The provision of the first sealing gasket 54 in this embodiment can improve the assembly sealing of the mounting seat 52 and the cyclone separation barrel 53, which is beneficial to ensure the negative pressure environment inside the main shell 1, so that the vacuum cleaner has sufficient suction force, which can greatly improve the separation and dust removal effect of the vacuum cleaner.

[0098] As a preferred technical solution, Figure 3 As shown, the lower portion of the outer cylinder 51 of this embodiment is tapered. This design can collect dust, debris, and other waste separated by the cyclone separation cylinder 53 for easy collection and disposal. As a preferred technical solution, a retaining ring 326 is provided on the inner side wall of the bottom cover 32 of this embodiment. When the bottom cover 32 is closed to the bottom end of the dust bin 31, the bottom end of the outer cylinder 51 can be located within the retaining ring 326. This arrangement allows the dust separated by the cyclone separation cylinder 53 to fall into the retaining ring 326 of the bottom cover 32, facilitating the disposal of dust, debris, and other waste, and reducing dust contamination of the dust bin 31.

[0099] As a preferred technical solution, Figure 3 As shown, in this embodiment, a second sealing gasket 327 is provided in the retaining ring 326 of the bottom cover 32. The provision of the second sealing gasket 327 can improve the sealing performance between the bottom of the outer cylinder 51 and the bottom cover 32, thereby preventing the separated dust from entering the dust bin 31.

[0100] like Figure 3 As shown, in this embodiment, the filter element 8 is arranged in the placement groove 522 of the mounting seat 52. In this embodiment, the filter element 8 can filter and purify the gas after cyclone separation again, further improving the dust removal effect of the utility model when used as a dust collector.

[0101] Specifically, such as Figure 14 As shown, the filter element 8 of this embodiment includes a bracket 81 and a filter screen 82, wherein the bracket 81 includes an outer bracket 811 and an inner bracket 812. In this embodiment, the outer bracket 811 is an annular structure, and the inner bracket 812 is a circular plate structure. A plurality of connectors 813 are connected between the outer bracket 811 and the inner bracket 812. The plurality of connectors 813 are evenly spaced along the circumference of the outer bracket 811 or the inner bracket 812 and are arranged between the outer bracket 811 and the inner bracket 812. In this embodiment, a filter screen 82 is fixedly provided on the side of the outer bracket 811 facing the mounting seat 53. In this embodiment, the filter screen 82 is a HEPA filter screen. It should be noted that the filter screen 82 of the present invention can also be made of other materials or types.

[0102] As a preferred technical solution, Figure 9 and Figure 14 As shown, in this embodiment, a third sealing ring 83 is provided on the bottom edge of the outer bracket 811 facing the mounting seat 52. The provision of the third sealing ring 83 can improve the sealing of the assembly of the filter element 8 and the mounting seat 52, thereby facilitating the maintenance of the negative pressure environment inside the main shell, so that the vacuum cleaner has sufficient suction force, which can greatly improve the separation and dust removal effect of the vacuum cleaner.

[0103] As a preferred technical solution, Figure 14 As shown, in this embodiment, a partition 814 is provided on each connecting member 813. The number of connecting members 813 provided is the same as the number of conical members 531 provided on the cyclone separator 53.

In this embodiment, the six partitions 814 on the bracket 81 divide the area between the outer bracket 811 and the inner bracket 812 into six airflow areas 815. When the filter element 8 is placed on the mounting base 52, the six airflow areas 815 correspond to the outlet of the air outlet 521. This design effectively uniforms the suction force, prevents airflow turbulence during return air flow, reduces the phenomenon of dust being entrained by the rising airflow, greatly improves separation efficiency, and thus helps improve the dust removal effect.

[0104] like Figure 8 、 Figure 10 and Figure 14 As shown, in this embodiment, a positioning column 527 is provided on the inner side wall of the placement groove 522 of the mounting seat 52, and a positioning groove 816 is provided on the side wall of the outer bracket 811. When the filter element 8 is placed in the placement groove 522, the positioning column 527 can be inserted into the positioning groove 816. In this embodiment, the setting of the positioning column 527 and the positioning groove 816 can limit the rotation of the filter element 8 in the placement groove 522.

[0105] By designing the number of positioning posts 527 and the position of the positioning posts 527 on the placement slot 522, the positioning posts 527 can play an anti-mistake role, that is, as long as the positioning slot 816 on the filter element 8 corresponds to the position of the positioning post 527 and is placed into the placement slot 522, the air flow area 815 on the filter element 8 can just correspond to the tube mouth of the air outlet tube 526. This design can effectively ensure the correct installation of the filter element 8 and can greatly simplify the user's operation.

[0106] In this embodiment, the cyclone separation dust removal device 3 has a three-stage filtering and purification function. Under the drive of the fan assembly 2, air carrying dust, debris and other garbage is sucked into the interior of the cyclone separation dust removal device 3 by the suction cylinder assembly 6. First, it is filtered and removed through the filter holes 511 on the outer cylinder 51 to remove large particles of debris and other garbage. Then, the air carrying dust and small particles of debris and other garbage is subjected to secondary dust removal through the cyclone separation cylinder 53. The air removed by the cyclone separation cylinder 53 can also pass through the filter mesh 82 of the filter element 8 for three-stage dust removal to ensure the cleanliness of the air entering the main shell 1 and discharged to the outside. On the one hand, it can effectively reduce the damage of dust to the fan assembly 2 inside the main shell 1 and improve the service life of the product; on the other hand, it can reduce the secondary pollution to the environment during the dust removal process and ensure the health of users.

[0107] like Figure 3 As shown, in this embodiment, the air inlet of the main housing 1 is provided with an assembly seat 9, which is detachably connected to the air inlet end of the main housing 1.

[0121] like Figures 18-20 As shown, in order to further improve the stability of the dust bin 31 and the assembly base 9 and prevent the dust bin 31 from being detached from the assembly base 9 due to accidental rotation of the dust bin 31, a switch lock 13 is further provided on the main housing 1 in this embodiment. Specifically, the switch lock 13 is provided at the bottom of the grip 12 in this embodiment.

[0122] like Figure 18 As shown, in this embodiment, the outer bottom of the gripping portion 121 is provided with a slide rail 14 along the axial direction of the gripping portion 121. Figure 19 As shown, in this embodiment, the switch lock 13 includes a movable switch 131 and a third elastic member 132, wherein the movable switch 131 is slidably arranged on the slide rail 14. Specifically, a slide groove 133 is provided on the movable switch 131, and the slide rail 14 is engaged in the slide groove 133.
