Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, specifically to a handheld vacuum cleaner. Background Technology

[0002] A handheld vacuum cleaner is a portable vacuum cleaning device that is powered by a battery or DC power source, generates negative pressure with a motor, and can be operated with one hand. It can clean various surfaces such as floors, crevices, fabrics, and car interiors.

[0003] Handheld vacuum cleaners typically consist of a housing, a dust collection mechanism, and a filter mechanism. The filter mechanism is used to filter dust in the airflow and needs to be frequently removed from the vacuum cleaner for cleaning. Usually, users need to remove the dust collection mechanism first before they can remove the filter mechanism, which is a cumbersome process and causes inconvenience to users. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a handheld vacuum cleaner that allows the filter mechanism to be directly removed from the housing without causing the dust collection mechanism and the housing to be reassembled.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a handheld vacuum cleaner, comprising a housing, a dust collection mechanism, and a filtering mechanism. The housing includes a mounting portion with a mounting groove for accommodating the filter mechanism. The mounting groove includes a front fixing plate and a rear fixing plate located on the front and rear sides of the filter mechanism, respectively, which secure the filter mechanism in place. The filter mechanism is detachably installed in the mounting slot, and the disassembly and assembly of the filter mechanism will not cause the dust collection mechanism and the housing to be reassembled.

[0006] Furthermore, the filtration mechanism includes: a disassembly assembly, a fixing assembly, a sealing assembly, and a filtering assembly. The disassembly assembly, the fixing assembly, the sealing assembly, and the filtering assembly are integrated into a single module, allowing the filtration mechanism to be completely disassembled from the housing in a single operation.

[0007] Furthermore, the filter assembly includes a fixing ring and a filter element, wherein the height of the fixing ring is greater than the width of the filter element, and the filter element can be fully accommodated within the fixing ring; The filter element includes a first filter element and a second filter element. The first filter element is disposed near the dust collection mechanism, and the second filter element is disposed near the motor. The filter diameter of the first filter element is larger than that of the second filter element. The first filter element, the second filter element, and the adsorption port of the motor are on the same straight line.

[0008] Furthermore, the sealing assembly includes a first sealing ring disposed on the fixing ring. The first sealing ring is disposed at one end of the fixing ring near the dust collection mechanism, and the first sealing ring and the fixing ring are integrally formed by a rubber coating process. The other side of the first sealing ring abuts against the front fixing plate.

[0009] Furthermore, an extrusion plate is provided on the side of the rear fixing plate near the filter mechanism. The extrusion plate is perpendicular to the rear fixing plate and is located in the lower middle part of the rear fixing plate. The width of the extrusion plate in the first direction increases from top to bottom.

[0010] Furthermore, an annular sealing groove is provided on the upper end face of the mounting groove wall along the opening of the mounting groove, and a second sealing element is provided in the sealing groove, the second sealing element abutting against the filter mechanism.

[0011] Furthermore, the disassembly and assembly assembly includes a first fixing plate, which serves as the outer surface of the housing and is shaped to fit the housing. The filter mechanism can be installed or disassembled by pressing or lifting the first fixing plate.

[0012] Furthermore, a disassembly groove is provided on the upper surface of the first fixing plate, and a hinge block is provided at the bottom of the disassembly groove. The hinge block is hinged to the disassembly plate, and the disassembly plate can rotate around the hinge point.

[0013] Furthermore, a reinforcing rib is provided between the bottom of the hinge block and the disassembly groove. The reinforcing rib is located directly below the pressing end of the disassembly plate. During the pressing process, the pressing end and the reinforcing rib abut against each other, and the reinforcing rib can limit the rotation angle of the disassembly plate.

[0014] Furthermore, a second pressing protrusion is provided on the lower side of the fixed ring, and the second pressing protrusion is fixedly connected to the lower side of the fixed ring. A bouncing device is provided at the bottom of the mounting groove, and the bouncing device is located directly below the second pressing protrusion. When the second pressing protrusion moves downward, it can squeeze the bouncing device, causing the bouncing device to bounce and apply an upward bouncing force to the fixed ring, driving the filter mechanism to bounce upward from the mounting groove.

[0015] Furthermore, a first pressing protrusion extending toward the fixing ring is provided on the lower surface of the first fixing plate, and the end of the first pressing protrusion can abut against the fixing ring; a pressing groove is provided on the surface of the first pressing protrusion near the fixing ring, and a limiting protrusion extending toward the first pressing protrusion is provided at a position where the fixing ring and the pressing groove are adapted, and the limiting protrusion is accommodated in the pressing groove.

[0016] Furthermore, the dust collection mechanism includes a dust cup, and a partition is provided inside the dust cup to divide the dust cup into a first dust cup and a second dust cup. A dust collection port is provided on the partition. The dust collection mechanism includes an air inlet channel provided at the front end of the first dust cup. The airflow entering the first dust cup through the air inlet channel can carry dust from the first dust cup to the second dust cup through the dust collection port. A dust removal port is provided at the front end of the second dust cup.

[0017] Furthermore, the lower sidewall of the housing and the partition are integrally connected to form the second dust cup, and the upper sidewall of the housing and the partition are snapped together to form the first dust cup; the handheld vacuum cleaner also includes a connecting mechanism, the connecting mechanism, the second dust cup, and the metal mesh are integrated into a cleaning module, which is detachably connected to the vacuum cleaner body through the connecting mechanism.

[0018] Beneficial effects: 1) By setting an installation slot on the housing, the installation slot can directly clamp and fix the filter mechanism. The filter mechanism can be installed or removed by directly inserting it into the installation slot or pulling it out of the installation slot. This will not cause the dust collection mechanism and the housing to be reassembled. The filter mechanism is very easy to install and remove, which improves the user's experience in installing and removing the filter mechanism.

[0019] 2) By integrating the components of the filter mechanism (disassembly and assembly components, the fixing components, the sealing components, and the filter components) into a single module, users only need to perform one operation during the disassembly and assembly of the filter to completely remove or install the filter components, thus improving the convenience of installing or removing the filter mechanism.

[0020] 3) In the sealing assembly, the sealing performance between the filter mechanism and the front fixed plate is improved through the cooperation of the first sealing ring and the extrusion member, ensuring that the airflow can pass through the filter mechanism. The filter mechanism filters the airflow, improving the overall airtightness of the vacuum cleaner.

[0021] 4) With the dual dust cups (first dust cup and second dust cup), users only need to empty the dust from the second dust cup. The second dust cup makes it convenient for users to clean the dust collected inside the vacuum cleaner.

[0022] 5) By integrating the connecting mechanism, the second dust cup, and the metal mesh into a single cleaning module, the cleaning module is detachably connected to the vacuum cleaner body via the connecting mechanism. When the user performs deep cleaning of the vacuum cleaner, the second dust cup and the metal mesh can be removed together to clean the bottom of the first dust cup (the upper side of the partition), the metal mesh, and the second dust cup, facilitating deep cleaning of the vacuum cleaner.

[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] For ease of subsequent description, this application will first combine [the following descriptions] before describing the specific structure of the vacuum cleaner. Figure 1 A first direction (front-back direction), a second direction (left-right direction), and a third direction (height direction) are defined. The first direction is the length direction of the vacuum cleaner when it is normally placed, such as the front-back direction; the second direction is the width direction of the vacuum cleaner when it is normally placed, such as the left-right direction; and the third direction is the height direction of the vacuum cleaner when it is normally placed, such as the up-down direction. In this application, the first direction (front-back direction), the second direction (left-right direction), and the third direction (height direction) are perpendicular to each other.

[0029] It is understood that the mutual perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing errors and assembly errors (e.g., the included angle between two structural features is 89.9°) is also within the scope of mutual perpendicularity in this application.

[0030] See appendix Figure 1 and attached Figure 2 As shown, a vacuum cleaner in this embodiment includes a housing 1, a dust collection mechanism 2, and a filter mechanism 3. It also includes a suction motor 5 installed inside the housing 1. The filter mechanism 3 and the dust collection mechanism 2 are both installed on the housing 1, and the filter mechanism 3 is fluidly connected between the dust collection mechanism 2 and the suction motor 5. When the suction motor 5 is working, dirty air outside the handheld vacuum cleaner can flow through the dust collection mechanism 2 and the filter mechanism 3 in sequence and be converted into clean air. Then, it flows through the suction motor 5 and is discharged outside the handheld vacuum cleaner, thereby realizing the vacuuming and cleaning work.

[0031] The filter mechanism 3 and the housing 1 are detachably connected. Under external force, the filter mechanism 3 can be directly removed from the vacuum cleaner without moving or disassembling other parts of the vacuum cleaner, making it convenient for users to clean or replace the filter. In other words, the installation position of other vacuum cleaner components such as the dust collection mechanism 2 does not affect the installation and removal of the filter mechanism 3. A portion of the surface of the filter mechanism 3 forms part of the external appearance of the handheld vacuum cleaner, allowing the filter mechanism 3 to be installed onto or removed from the housing 1 through the area defined by this external appearance. Thus, the filter mechanism 3 can be removed from or installed onto the housing 1 without removing the dust collection mechanism 2 from the housing 1, or without disassembling the housing 1 itself. This effectively improves the efficiency of installing and removing the filter mechanism 3, making it easier for users and enhancing the user experience.

[0032] In some embodiments, see Appendix Figure 2-4 As shown in Figure 9, the housing 1 includes a mounting part 13, which is located between the motor 5 and the dust collection mechanism 2. The mounting part 13 is used to fix the filter mechanism 3, so that the filter mechanism 3 is located between the dust collection mechanism 2 and the motor 5. After the air is processed by the dust collection mechanism 2, it is filtered by the filter mechanism 3 and then flows out through the motor 5.

[0033] A downwardly extending mounting groove 131 is provided on the upper side of the mounting part 13, which is used to accommodate the filter mechanism 3. The front side and rear side of the mounting groove 131 are fixed plates 132 for fixing the filter mechanism 3, and through holes 133 are provided on the fixed plates 132 for air to flow through them.

[0034] The fixing plate 132 includes a front fixing plate 1321 and a rear fixing plate 1322 located on the front and rear sides of the filter mechanism 3, which can clamp the filter mechanism 3. By providing a mounting groove 131 on the housing, the mounting groove 131 can directly clamp and fix the filter mechanism 3. The installation or removal of the filter mechanism 3 can be completed by directly inserting the filter mechanism 3 into the mounting groove 131 or directly pulling it out of the mounting groove 131, without causing the dust collection mechanism 2 and the housing 1 to reassemble. The installation and removal of the filter mechanism 3 is very convenient, improving the user's experience in installing and removing the filter mechanism.

[0035] In some embodiments, the upper end face of the mounting groove 131 abuts against the first fixing plate 311 of the filter assembly 34. An annular sealing groove 134 is provided along the opening of the mounting groove 131 on the upper end face of the groove wall. A second sealing member is provided in the sealing groove 134. The second sealing member abuts against the first fixing plate 311 of the filter mechanism 3. By providing the second sealing member, airflow is prevented from overflowing from the gap between the mounting groove 131 and the first fixing plate 311, thereby improving the sealing performance between the mounting part 13 and the filter mechanism 3.

[0036] In some embodiments, the filter mechanism 3 includes a sealing assembly 33, which includes a first sealing ring 331 disposed on a fixing ring 343. The first sealing ring 331 is disposed at one end of the fixing ring 343 near the dust collection mechanism 2. The first sealing ring 331 can be sleeved on the front end of the fixing ring 343 and integrally formed with the fixing ring 343 by an overmolding process. The other side of the first sealing ring 331 abuts against the front fixing plate 1321 located at the front end of the mounting part 13. The first sealing ring 331 ensures that when the filter mechanism 3 is located in the mounting groove 131, there is no gap between the front fixing plate 1321 located at the front end of the mounting part 13 and the filter mechanism 3, and all air can enter the filter mechanism 3 for filtration through the through hole 133 of the front fixing plate 1321. This prevents dusty airflow from escaping through the gap between the front fixing plate 1321 and the filter mechanism 3 without being filtered by the filter mechanism 3. The first sealing ring 331 enhances the seal between the front fixing plate 1321 of the mounting section 13 and the filter mechanism 3, ensuring that all airflow containing dust is filtered by the filter mechanism 3. Furthermore, the first sealing ring 331 and the fixing ring 343 are integrally molded using a rubber-coating process, improving the stability of the connection between them. The first sealing ring 331 is installed and removed simultaneously from the mounting groove 131 along with the fixing ring 343, enhancing the convenience of disassembling or installing the filter mechanism 3.

[0037] In some embodiments, a compression plate 332 is provided on the side of the rear fixing plate 1322 near the filter mechanism 3 (see Appendix). Figure 3 As shown, the extrusion plate 332 and the rear fixing plate 1322 are vertically arranged, with the extrusion plate 332 located in the lower middle part of the rear fixing plate 1322. The height of the extrusion plate 332 increases from top to bottom in the front-to-back direction. During the installation of the filter mechanism 3, when the filter mechanism 3 moves downward, the extrusion plate 332 presses the filter mechanism 3 towards the front fixing plate 1321, ensuring that there are no gaps between the first sealing ring 331 and the front fixing plate 1321, thus improving the sealing effect of the first sealing ring 331. By setting the extrusion plate 332 on the rear fixing plate 1322, the sealing between the filter mechanism 3 and the front fixing plate 1321 is further improved, ensuring that airflow can pass through the filter mechanism 3. The filter mechanism 3 filters the airflow, improving the overall airtightness of the vacuum cleaner.

[0038] See appendix Figure 2-6As shown, in some embodiments, the filter mechanism 3 includes a fixing component 32 for fixing the filter mechanism 3 and the mounting part 13. The fixing component 32 includes a fixing groove 321 disposed on the fixing plate 132, the opening direction of the fixing groove 321 being closer to the filter mechanism 3, and a spring 322 disposed at the bottom of the fixing groove 321, the entire area of ​​the spring 322 being accommodated within the fixing groove 321. A snap-fit ​​member 323 is disposed at the end of the spring 322 away from the bottom of the fixing groove 321, at least a portion of the snap-fit ​​member 323 being accommodated within the fixing groove 321, and the fixing groove 321 supporting the spring 322 and the snap-fit ​​member 323. Under the action of the elastic force of the spring 322, the snap-fit ​​member 323 can move closer to or away from the filter mechanism 3 along the wall of the fixing groove 321.

[0039] In some embodiments, a first snap-fit ​​groove 324 is provided on the filter mechanism 3. The position, size, and shape of the first snap-fit ​​groove 324 are adapted to the snap-fit ​​member 323. During the installation of the filter mechanism 3, the filter mechanism 3 is pressed down, and the snap-fit ​​member 323 can be accommodated in the first snap-fit ​​groove 324. When the filter mechanism 3 is disassembled, the filter mechanism 3 is pulled up, and the snap-fit ​​member 323 retracts towards the spring 322 under the action of external force, disengaging from the first snap-fit ​​groove 324, and the filter mechanism 3 is removed from the vacuum cleaner. The end of the snap-fit ​​member 323 near the first snap-fit ​​groove 324 has a frustum structure and a smooth transition from the top to the side, which facilitates the disengagement of the snap-fit ​​member 323 from the first snap-fit ​​groove 324.

[0040] See appendix Figure 2 , 7 As shown in Figures 8 and 9, in some embodiments, the filter component 34 is a ring structure, located at the front end of the motor 5, and at the same height as the adsorption port of the motor 5. After passing through the filter component 34, the airflow directly enters the adsorption port of the motor 5 without turning, which can improve the adsorption effect of the motor 5 on dust.

[0041] The filter assembly 34 includes a retaining ring 343 and a filter element. The width of the retaining ring 343 in the lateral direction is greater than the width of the filter element, and the filter element can be accommodated within the retaining ring 343. The filter element includes a first filter element 341 and a second filter element 342, which are fitted together. The first filter element 341 is located near the dust collection mechanism 2, and the second filter element 342 is located near the motor 5. After the air is processed by the dust collection mechanism 2, it first passes through the first filter element 341 for filtration, and then through the second filter element 342 for filtration. The filter diameter of the first filter element 341 is larger than that of the second filter element 342, meaning that the smallest dust particle size that the first filter element 341 can filter is larger than that that the second filter element 342 can filter. In other words, the first filter element 341 performs coarse filtration relative to the second filter element 342, and the second filter element 342 performs fine filtration relative to the first filter element 341.

[0042] The airflow undergoes coarse filtration through the first filter element 341 and fine filtration through the second filter element 342, which can effectively improve the filtration effect of the filter assembly 34, improve the cleanliness of the airflow flowing to the motor 5, and enable the motor 5 to work stably for a long time.

[0043] In some embodiments, the first filter element 341 is a sponge, and the second filter element 342 is a HEPA filter. The sponge first performs coarse filtration of the air, trapping most of the larger dust particles; the HEPA filter performs fine filtration of the air, preventing dust from flowing towards the motor 5.

[0044] In some embodiments, the thickness of the retaining ring 343 is greater than the sum of the thicknesses of the first filter element 341 and the second filter element 342, ensuring that the first filter element 341 and the second filter element 342 can be simultaneously accommodated in the cavity of the retaining ring 343. The retaining ring 343 simultaneously fixes the first filter element 341 and the second filter element 342. When the filter assembly 34 is disassembled or installed, the second filter element 342 and the second filter element 342 are installed or removed simultaneously along with the retaining ring 343, improving the efficiency and convenience of installing or disassembling the filter assembly 34.

[0045] In some embodiments, a limiting ring 344 is provided at the end of the fixing ring 343 away from the first sealing ring 331. The limiting ring 344 and the fixing ring 343 are integrally connected, and the limiting ring 344 extends towards the filter element, so that the inner diameter of the limiting ring 344 is smaller than the outer diameter of the filter element. The limiting ring 344 can stop and limit the filter element, so that the filter element can be stably accommodated in the fixing ring 343, which is beneficial for the overall disassembly and installation of the filter mechanism 3.

[0046] Participate in the attached Figure 3 , 9 As shown in Figure 10, in some embodiments, the filter mechanism 3 includes a disassembly assembly 31 for removing the filter mechanism 3 from the vacuum cleaner or installing the filter mechanism 3 onto the vacuum cleaner. The disassembly assembly 31 includes a first fixing plate 311, which serves as the outer surface of the housing 1. Its shape is adapted to the housing 1. When the filter mechanism 3 is installed on the vacuum cleaner, the first fixing plate 311 and the housing 1 form a complete outer surface. That is, when the housing 1 around the first fixing plate 311 is a curved surface, the first fixing plate 311 is a curved plate with a matching curvature; when the housing 1 around the first fixing plate 311 is a flat surface, the first fixing plate 311 has a flat structure to improve the aesthetics of the vacuum cleaner and also improve the sealing between the filter mechanism 3 and the housing 1.

[0047] A disassembly groove 312 is provided on the upper surface of the first fixed plate 311, and a hinge block 313 is provided at the bottom of the disassembly groove 312. The hinge block 313 and the disassembly plate 315 are hinged together, and the disassembly plate 315 can rotate around the hinge point. The size and shape of the disassembly plate 315 are adapted to the size and shape of the groove opening of the disassembly groove 312, that is, the disassembly plate 315 and the first fixed plate 311 form a complete appearance surface.

[0048] Specifically, hinge holes 3131 are provided on the front and rear sides of the hinge block 313, and a hinge protrusion is provided on the lower side of the disassembly plate 315. A hinge shaft 3151 is provided on the hinge protrusion. The hinge shaft 3151 can be accommodated in the hinge hole 3131, and the disassembly plate 315 can rotate around the hinge shaft 3151.

[0049] In some embodiments, the hinge hole 3131 is located at the center of the disassembly groove 312 in the front-back direction. During the rotation of the disassembly plate 315 around the hinge shaft 3151, one end of the hinge plate is pressed down (pressed end 3152), and the other end is lifted up (lifted end 3153). The user can remove the filter mechanism 3 from the vacuum cleaner by pulling it upward through the lifted end 3153.

[0050] Preferably, the hinge hole 3131 is not located at the center of the disassembly groove 312 in the front-rear direction, but rather at a position one-third or two-thirds of the way into the front side of the disassembly groove 312. That is, the ratio of the distance from the hinge hole 3131 to the side wall of the disassembly groove 312 in the first direction (front-rear direction) to the length of the disassembly groove 312 in the first direction (front-rear direction) is one-third or two-thirds. During use, the length ratio of the pressing end 3152 to the lifting end 3153 of the disassembly plate 315 is 1:2. During the pressing process, the lifting end 3153 is raised to a relatively high height, which is beneficial for the user to pull upwards.

[0051] In some embodiments, a reinforcing rib 314 is provided between the bottom of the hinge block 313 and the disassembly groove 312 to fix the hinge block 313. The reinforcing rib 314 is located directly below the pressing end 3152. During the pressing of the pressing end 3152, the pressing end 3152 and the reinforcing rib 314 abut against each other, and the reinforcing rib 314 can limit the downward rotation of the pressing end 3152. If the range of the pressing end 3152 is not limited, when the rotation angle of the lifting end 3153 is relatively large, such as 80°, it is not conducive to the user applying upward force to pull it up. The rotation angle of the disassembly plate 315 is 20-60 degrees, and the rotation angle of the disassembly plate 315 can be limited by setting the height of the reinforcing rib 314.

[0052] See appendix Figure 11-14As shown, in some other embodiments, a first pressing protrusion 3161 extending toward the fixing ring 343 is provided on the lower surface of the first fixing plate 311. The end of the first pressing protrusion 3161 abuts against the fixing ring 343. When the first fixing plate 311 is pressed down, the first fixing plate 311 presses down the fixing ring 343 by pressing down the first pressing protrusion 3161, causing the fixing ring 343 to move downward.

[0053] In some embodiments, the first pressing protrusion 3161 has a pressing groove 3162 on its surface near the fixing ring 343, and a limiting protrusion 3163 extending toward the first pressing protrusion 3161 is provided at a position where the fixing ring 343 and the pressing groove 3162 are adapted to each other. The limiting protrusion 3163 is accommodated in the pressing groove 3162. By providing the pressing groove 3162 and the limiting protrusion 3163, the relative position of the fixing ring 343 and the first fixing plate 311 is fixed to prevent the fixing ring 343 from shaking during the pressing process.

[0054] In some embodiments, the disassembly assembly 31 includes a lifting assembly 317. The lifting assembly 317 includes a first lifting member 3171 extending toward the fixing ring 343 on the lower surface of the first fixing plate 311, and a second lifting member 3173 extending toward the first fixing plate 311 on the fixing ring 343. A first protrusion 3172 extending toward the second lifting member 3173 is provided at the end of the first lifting member 3171, and a second protrusion 3174 extending toward the first lifting member 3171 is provided at the end of the second lifting member 3173. The upper surface of the first protrusion 3172 and the lower surface of the second protrusion 3174 are fitted together. When disassembling the filter mechanism 3, the first fixing plate 311 is pulled up, and then the fixing ring 343 is pulled up by the first lifting member 3171, the first protrusion 3172, the second protrusion 3174, and the second lifting member 3173, thereby removing the filter mechanism 3.

[0055] In some embodiments, the lifting assembly 317 is provided in two sets, symmetrically arranged on the left and right sides of the limiting protrusion 3163, to ensure that the fixing ring 343 is subjected to uniform force during the upward pulling process, making it easy to remove the fixing ring 343.

[0056] In some embodiments, a second pressing protrusion 318 is provided on the lower side of the fixing ring 343. The second pressing protrusion 318 is fixedly connected to the lower side of the fixing ring 343, and the fixing ring 343 drives the second pressing protrusion 318 to move up and down. A bouncer 319 is provided at the bottom of the mounting groove 131. The bouncer 319 is located directly below the second pressing protrusion 318. When the second pressing protrusion 318 moves downward, it can squeeze the bouncer 319, causing the bouncer 319 to bounce and apply an upward supporting force to the fixing ring 343, causing the fixing ring 343 to move upward. That is, the filter mechanism 3 bounces upward from the mounting groove 131, and the user can directly remove the filter mechanism 3 upward.

[0057] The filter mechanism 3 is easy to assemble and disassemble. To remove it, simply press down on the first fixing plate 311, and the filter mechanism 3 will spring upward from the mounting slot 131, allowing the user to easily remove it. For installation, simply press down on the first fixing plate 311 to allow the filter mechanism 3 to fit into the mounting slot 131. This design facilitates user operation and enhances the user experience.

[0058] During use, when removing the filter mechanism 3 from the vacuum cleaner, the user can simply hold the main body with one hand and remove the filter mechanism 3 with the other hand in a very short and effortless process. Afterwards, the user can put down the main body, take the compact filter mechanism 3 to the cleaning position, and then easily disassemble the filter mechanism 3 to remove the filter component 34 for cleaning. After cleaning, the filter component 34 is put back into the retaining ring 343 of the filter mechanism 3. Then, the filter mechanism 3 is taken back to the main body. Holding the main body with one hand, the user can simply put the filter mechanism 3 back into the main body with the other hand in a very quick and effortless operation.

[0059] See appendix Figure 2 and 15 As shown in Figure 18, in some embodiments, the dust collection mechanism 2 includes a dust cup, and a partition 25 is provided inside the dust cup to divide the dust cup into a first dust cup 23 and a second dust cup 24. A dust collection port 251 is provided on the partition 25. Gas, dust and debris in the first dust cup 23 can enter the second dust cup 24 with the airflow. As more gas enters the second dust cup 24, the gas in the second dust cup 24 can overflow through the dust collection port 251 and enter the first dust cup 23. Under the action of the motor 5, after being filtered by the filter mechanism 3, it flows out from the air outlet located at the rear end of the vacuum cleaner.

[0060] In some embodiments, the dust collection mechanism 2 includes an air inlet channel 21, which is located at the front end of the vacuum cleaner. A spiral channel 22 is located at the rear end of the air inlet channel 21. The first dust cup 23 and the spiral channel 22 are in fluid communication. After air enters the spiral channel 22 through the air inlet channel 21, it forms a cyclone and enters the first dust cup 23. The airflow entering the first dust cup 23 can be separated by cyclone, and the dust separated by cyclone in the first dust cup 23 can enter the second dust cup 24 through the dust outlet 251.

[0061] During normal use, approximately 90% of the dust enters the second dust cup 24 through the dust outlet 251. Even if a small amount of dust remains in the first dust cup 23, it will be separated again by the cyclone and enter the second dust cup 24 when the vacuum cleaner is used again. Therefore, during normal use, only the second dust cup 24 needs to be cleaned.

[0062] A dust removal cover 241 is provided at the front end of the second dust cup 24, and is hinged to the second dust cup body 242. When it is necessary to clean the dust in the second dust cup 24, simply open the dust removal cover 241 to empty it; there is no need to remove the second dust cup 24, making it extremely convenient to handle the dust or debris inside. In other words, by providing the second dust cup 24, users can easily clean the dust collected inside the vacuum cleaner.

[0063] In some embodiments, the lower sidewall 12 of the housing 1 and the spacer 25 are integrally connected to form a second dust cup 24, improving the sealing performance of the second dust cup 24. The upper sidewall 11 of the housing 1 and the spacer 25 are snapped together to form a first dust cup 23. The first dust cup 23 and the second dust cup 24 share the spacer 25, making the vacuum cleaner structure more compact and lightweight, and improving the user experience.

[0064] In some embodiments, a metal mesh 26 is disposed inside the cavity of the first dust cup 23, and the metal mesh 26 is positioned directly above the dust collection port 251. The metal mesh 26 has a frustum-shaped or conical structure and protrudes towards the front end of the vacuum cleaner. The metal mesh 26 can block large particles of dust or debris, allowing them to enter the second dust cup 24.

[0065] In some embodiments, the vacuum cleaner includes a connecting mechanism 4, the connecting mechanism 4, the second dust cup 24, and the metal mesh 26 are integrated into a cleaning module. The cleaning module is detachably connected to the vacuum cleaner body via the connecting mechanism 4. When the user cleans the first dust cup, the second dust cup, and the metal mesh of the vacuum cleaner, the second dust cup 24 can be removed together with the metal mesh 26, and the bottom of the first dust cup 23 (the upper side of the partition 25), the metal mesh 26, and the second dust cup 24 can be cleaned together, facilitating deep cleaning of the vacuum cleaner.

[0066] In some embodiments, the connecting mechanism 4 is disposed between the mounting portion 13 and the dust collection mechanism 2, and the connecting mechanism 4 and the rear end of the dust collection mechanism 2 are fixedly connected. The connecting mechanism 4 includes a button 41 as part of the outer surface, and a snap-fit ​​protrusion 42 connected to the button 41, the snap-fit ​​protrusion 42 being able to extend and retract with the button 41 in a second direction (left-right direction). A second snap-fit ​​groove 44 is provided at a corresponding position on the inner side of the mounting portion 13. The snap-fit ​​protrusion 42 can be accommodated in the second snap-fit ​​groove 44, thereby connecting the mounting portion 13 and the dust collection mechanism 2.

[0067] In some embodiments, the connecting mechanism 4 includes a positioning protrusion 43 extending toward the mounting portion 13, and a positioning groove 45 is provided at a corresponding position on the inner side of the mounting portion 13. During the installation of the dust collection mechanism 2, the positioning protrusion 43 slides along the positioning groove 45 to ensure that the snap-fit ​​protrusion 42 can be accommodated in the second snap-fit ​​groove 44, thereby improving the convenience of installation.

[0068] In some embodiments, a first partition plate 14 and a second partition plate 15 are provided at the front end of the vacuum cleaner. The first partition plate 14 is fixedly connected to the upper side wall 11, and the second partition plate 15 is fixedly connected to the spacer 25. The connecting mechanism 4 also includes a first snap-fit ​​member 46 provided on the first partition plate 14 and a second snap-fit ​​member 47 provided at a corresponding position on the second partition plate 15. The first snap-fit ​​member 46 and the second snap-fit ​​member 47 can snap into each other to fix the front ends of the first dust cup 23 and the second dust cup 24.

[0069] The second dust cup 24 is fixed by setting the first snap-fit ​​part 46 and the second snap-fit ​​part 47 at the front end of the vacuum cleaner, and the other end of the second dust cup 24 is fixed by setting the snap-fit ​​protrusion 42 and the second snap-fit ​​groove 44. The second dust cup 24 and the metal mesh 26 are installed together on the vacuum cleaner, which makes it convenient for users to remove the first dust cup, the second dust cup and the metal mesh for deep cleaning of the vacuum cleaner.
