DESCRIPTION OF THE EMBODIMENTS

In order to make the above objectives, characteristics and advantages of the present disclosure more obvious and understandable, the specific implementations of the present disclosure are described in detail below in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate full understanding of the present disclosure. However, the present disclosure can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without violating the connotation of the present disclosure. Therefore, the present disclosure is not limited by the specific embodiments disclosed below.

For the convenience of subsequent description, before describing a specific structure of a vacuum cleaner, the present application first defines a first direction (front-rear direction), a second direction (left-right direction), and a third direction (height direction) in conjunction with FIG. 1. The first direction is a length direction of the vacuum cleaner when it is placed normally, such as the front-rear direction. The second direction is a width direction of the vacuum cleaner when it is placed normally, such as the left-right direction. The third direction is the height direction of the vacuum cleaner when it is placed normally, such as an upper-lower direction. In the present application, the first direction (front-rear direction), the second direction (left-right direction), and the third direction (height direction) are perpendicular to each other.

It can be understood that the mutual perpendicularity in the present application is not absolute perpendicularity, and the approximate perpendicularity caused by processing errors and assembly errors (for example, an included angle between two structural features is 89.9°) is also within a range of mutual perpendicularity in the present application.

As shown in FIG. 1 and FIG. 2, a vacuum cleaner in the present embodiment includes a housing 1, a dust collecting mechanism 2, and a filtering mechanism 3, and further includes a suction motor 5 installed inside the housing 1. The filtering mechanism 3 and the dust collecting mechanism 2 are both installed on the housing 1, and the filtering mechanism 3 is in fluid communication between the dust collecting mechanism 2 and the suction motor 5. When the suction motor 5 works, dirty air outside the handheld vacuum cleaner may sequentially flow through the dust collecting mechanism 2 and the filtering mechanism 3 to be converted into clean air, and then flows through the suction motor 5 to be discharged to the exterior of the handheld vacuum cleaner, thereby achieving dust absorption and cleaning work.

The filtering mechanism 3 is detachably connected to the housing 1. Under driving of an external force, the filtering mechanism 3 can be directly disassembled from the vacuum cleaner without moving or disassembling other mechanisms of the vacuum cleaner, thereby making it convenient for a user to clean or replace a filtering element. That is to say, installation positions of the dust collecting mechanism 2 and other parts of the vacuum cleaner do not affect the disassembly and installation of the filtering mechanism 3. A portion of surface of the filtering mechanism 3 constitutes a portion of appearance surface of the handheld vacuum cleaner, and the filtering mechanism 3 can be installed to the housing 1 or disassembled from the housing 1 through a region defined by this portion of appearance surface. In this way, the filtering mechanism 3 can be disassembled from the housing 1 or installed on the housing 1 without disassembling the dust collecting mechanism 2 from the housing 1 and disassembling the housing 1. As a result, the efficiency of disassembling and installing the filtering mechanism 3 can be effectively improved, making it easier for the user to use and enhancing the user experience.

In some embodiments, as shown in FIG. 2 to FIG. 4, and FIG. 9, the housing 1 includes an installation part 13, the installation part 13 is located between the motor 5 and the dust collecting mechanism 2, and is used for fixing the filtering mechanism 3, so that the filtering mechanism 3 is located between the dust collecting mechanism 2 and the motor 5. After being treated by the dust collecting mechanism 2, air is filtered by the filtering mechanism 3 and flows out through the motor 5.

A downward-extending installation groove 131 is formed in an upper side surface of the installation part 13, and the installation groove 131 is used for accommodating the filtering mechanism 3. Fixing plates 132 for fixing the filtering mechanism 3 are arranged on a front side surface and a rear side surface of the installation grooves 131, and through holes 133 are formed in the fixing plates 132 for air circulation.

The fixing plates 132 include a front fixing plate 1321 and a rear fixing plate 1322 which are located on front and rear sides of the filtering mechanism 3, and the front fixing plate 1321 and the rear fixing plate 1322 are able to clamp the filtering mechanism 3. By forming the installation groove 131 in the housing, the installation groove 131 can directly clamp and fix the filtering mechanism 3. The installation or disassembly of the filtering mechanism 3 can be completed by directly inserting the filtering mechanism 3 into the installation groove 131 or directly pulling the filtering mechanism out of the installation groove 131, without causing the dust collecting mechanism 2 and the housing 1 to be reassembled. The disassembly and installation of the filtering mechanism 3 are very convenient, and the user's experience of disassembling and installing the filtering mechanism is improved.

In some embodiments, an upper end surface of a groove wall of the installation groove 131 abuts against the first fixing plate 311 of a filtering assembly 34. An annular sealing groove 134 is formed, along a notch of the installation groove 131, in the upper end surface of the groove wall, a second sealing element is arranged in the sealing groove 134, and the second sealing element abuts against the first fixing plate 311 of the filtering mechanism 3. By arranging the second sealing element, an airflow is prevented from overflowing from a gap between the installation groove 131 and the first fixing plate 311, thereby improving the sealing performance between the installation part 13 and the filtering mechanism 3.

In some embodiments, the filtering mechanism 3 includes a sealing assembly 33, the sealing assembly 33 includes a first sealing ring 331 arranged on a fixing ring 343, the first sealing ring 331 is arranged at one end of the fixing ring 343 close to the dust collecting mechanism 2, the first sealing ring 331 may be arranged at a front end of the fixing ring 343 in a sleeving manner, and the first sealing ring and the fixing ring 343 are integrally formed by a rubber coating process. The other side surface of the first sealing ring 331 abuts against the front fixing plate 1321 located at a front end of the installation part 13. By arranging the first sealing ring 331, it is ensured that when the filtering mechanism 3 is located in the installation groove 131, there is no gap between the front fixing plate 1321 located at the front end of the installation part 13 and the filtering mechanism 3, and all air can enter the filtering mechanism 3 through the through hole 133 of the front fixing plate 1321 for filtering. A dusty airflow is prevented from overflowing through the gap between the front fixing plate 1321 and the filtering mechanism 3 without being filtered by the filtering mechanism 3. By arranging the first sealing ring 331, the sealing performance between the front fixing plate 1321 of the installation part 13 and the filtering mechanism 3 is improved, thereby ensuring that the dusty airflow is filtered through the filtering mechanism 3. The first sealing ring 331 and the fixing ring 343 are integrally formed by the rubber coating process, thus the stability of a connection between the first sealing ring 331 and the fixing ring 343 is improved. That is, the first sealing ring 331 is installed and disassembled synchronously with the fixing ring 343 from the interior of the installation groove 131, thereby enhancing the convenience of disassembling or installing the filtering mechanism 3.

In some embodiments, an extruding plate 332 (as shown in FIG. 3) is arranged on one side of the rear fixing plate 1322 close to the filtering mechanism 3, the extruding plate 332 and the rear fixing plate 1322 are vertically arranged, the extruding plate 332 is located in a lower middle portion of the rear fixing plate 1322, and a height of the extruding plate 332 in a front-rear direction progressively increases from top to bottom. In a process of installing the filtering mechanism 3, when the filtering mechanism 3 moves downwards, the extruding plate 332 pressurizes the filtering mechanism 3 in a direction of the front fixing plate 1321, so as to ensure that there is no gap between the first sealing ring 331 and the front fixing plate 1321, thereby improving a sealing effect of the first sealing ring 331. By arranging the extruding plate 332 on the rear fixing plate 1322, the sealing performance between the filtering mechanism 3 and the front fixing plate 1321 is further enhanced, ensuring that the airflow can flow through the filtering mechanism 3 and the filtering mechanism 3 filters the airflow, thereby improving the overall airtightness of the vacuum cleaner.

As shown in FIG. 2 to FIG. 6, in some embodiments, the filtering mechanism 3 includes a fixing assembly 32 for fixing the filtering mechanism 3 and the installation part 13. The fixing assembly 32 includes a fixing groove 321 formed in the fixing plate 132. An opening direction of the fixing groove 321 is a direction close to the filtering mechanism 3. A spring 322 is arranged at a bottom of the fixing groove 321, and an entire region of the spring 322 is accommodated in the fixing groove 321. A clamping element 323 is arranged at one end of the spring 322 away from a bottom of the fixing groove 321, and at least a partial region of the clamping element 323 is accommodated in the fixing groove 321. The fixing groove 321 supports the spring 322 and the clamping element 323. Under the action of an elastic force of the spring 322, the clamping element 323 can approach or move away from the filtering mechanism 3 along a wall of the fixing groove 321.

In some embodiments, a first clamping groove 324 is formed in the filtering mechanism 3, and a position, size, and shape of the first clamping groove 324 are adapted to the clamping element 323. In a process of installing the filtering mechanism 3, the filtering mechanism 3 is pressed down, and the clamping element 323 can be accommodated in the first clamping groove 324. When the filtering mechanism 3 is disassembled, the filtering mechanism 3 is pulled up, and the clamping element 323 contracts towards the spring 322 under the action of an external force, and is disengaged from the first clamping groove 324, so that the filtering mechanism 3 is disassembled from the vacuum cleaner. An end of the clamping element 323 close to the first clamping groove 324 is of a circular truncated cone structure, and there is a smooth transition from the top to the side surface, which is beneficial for the clamping element 323 to be disengaged from the first clamping groove 324.

As shown in FIGS. 2, 7, and 8, in some embodiments, the filtering assembly 34 is of an annular structure and is located at a front end of the motor 5, and the filtering assembly and an adsorption port of the motor 5 are located at the same height. After passing through the filtering assembly 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.

The filtering assembly 34 includes a fixing ring 343 and a filtering element, a width of the fixing ring 343 in a transversal direction is greater than a width of the filtering element, and the filtering element is able to be accommodated in the fixing ring 343. The filtering element includes a first filtering element 341 and a second filtering element 342. The first filtering element 341 and the second filtering element 342 are arranged in a fit manner, the first filtering element 341 is arranged close to the dust collecting mechanism 2, and the second filtering element 342 is arranged close to the motor 5. After being treated by the dust collecting mechanism 2, the air is first filtered through the first filtering element 341 and then filtered through the second filtering element 342. A filter diameter of the first filtering element 341 is greater than that of the second filtering element 342, that is, a minimum dust particle size that the first filtering element 341 can filter out is greater than a minimum dust particle size that the second filtering element 342 can filter out. That is to say, the first filtering element 341 achieves coarse filtration relative to the second filtering element 342, and the second filtering element 342 achieves fine filtration relative to the first filtering element 341.

The airflow passes through the first filtering element 341 for coarse filtration, and then passes through the second filtering element 342 for fine filtration, which can effectively improve the filtering effect of the filtering assembly 34, enhance the cleanliness of the airflow flowing towards the motor 5, and enable the motor 5 to work stably for a long time.

In some embodiments, the first filtering element 341 is sponge, and the second filtering element 342 is HEPA. The sponge first performs coarse filtration on the air to intercept most of dust with larger particle sizes; and the HEPA performs fine filtration on the air to prevent the dust from flowing towards the motor 5.

In some embodiments, a thickness of the fixing ring 343 is greater than a sum of the thicknesses of the first filtering element 341 and the second filtering element 342, ensuring that the first filtering element 341 and the second filtering element 342 can be simultaneously accommodated in a chamber of the fixing ring 343, and the fixing ring 343 fixes the first filtering element 341 and the second filtering element 342 at the same time. When the filtering assembly 34 is disassembled or installed, the first filtering element 341 and the second filtering element 342 are simultaneously installed or disassembled with the fixing ring 343, thereby improving the efficiency and convenience of installing or disassembling the filtering assembly 34.

In some embodiments, a limiting ring 344 is arranged at one 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 filtering element, so that an inner diameter of the limiting ring 344 is smaller than an outer diameter of the filtering element. The limiting ring 344 can stop and limit the filtering element, so that the filtering element can be stably accommodated in the fixing ring 343, which is conducive to the overall disassembly and installation of the filtering mechanism 3.

As shown in FIGS. 3, 9 and 10, in some embodiments, the filtering mechanism 3 includes a disassembly-installation assembly 31, and the disassembly-installation assembly 31 is used for disassembling the filtering mechanism 3 from the vacuum cleaner or installing the filtering mechanism 3 on the vacuum cleaner. The disassembly-installation assembly 31 includes a first fixing plate 311, the first fixing plate 311 serves as an appearance surface of the housing 1, and a shape of the first fixing plate is adapted to the housing 1. When the filtering mechanism 3 is installed on the vacuum cleaner, the first fixing plate 311 and the housing 1 form a complete appearance surface. That is to say, when the housing 1 around the first fixing plate 311 is an arc-shaped surface, the first fixing plate 311 is an arc-shaped plate with the adapted curvature. When the housing 1 around the first fixing plate 311 is a plane, the first fixing plate 311 is of a planar structure, so as to enhance an aesthetic degree of the vacuum cleaner and improve a sealing degree between the filtering mechanism 3 and the housing 1.

A disassembly groove 312 is formed in an upper surface of the first fixing plate 311, a hinge block 313 is arranged at a bottom of the disassembly groove 312, the hinge block 313 is hinged with a disassembly plate 315, and the disassembly plate 315 is able to rotate around a hinge point. A size and shape of the disassembly plate 315 are adapted to a size and shape of a notch of the disassembly groove 312. That is to say, the disassembly plate 315 and the first fixing plate 311 form a complete appearance surface.

Specifically, hinge holes 3131 are formed in front and rear sides of the hinge block 313, and a hinge protrusion is arranged on a lower side surface of the disassembly plate 315. An articulated shaft 3151 is arranged on the hinge protrusion, the articulated shaft 3151 can be accommodated in the hinge holes 3131, and the disassembly plate 315 can rotate around the articulated shaft 3151.

In some embodiments, the hinge holes 3131 are formed in a center position of the disassembly groove 312 in a front-rear direction. During the rotation of the disassembly plate 315 around the articulated shaft 3151, one end (down-pressing end 3152) of the hinge plate is pressed down, and the other end (a lifting end 3153) is lifted upward. The user can take the filtering mechanism 3 out of the vacuum cleaner by pulling the lifting end 3153 upwards with force.

Preferably, the hinge holes 3131 are not formed in the center position of the disassembly groove 312 in the front-rear direction, but rather in a position â…“ or â…” close to the front side surface of the disassembly groove 312. That is, a ratio of a distance from the hinge holes 3131 to a side wall of the disassembly groove 312 in a first direction (front-rear direction) to a length of the disassembly groove 312 in the first direction (front-rear direction) is â…“ or â…”. During use, a ratio of lengths of the down-pressing end 3152 and the lifting end 3153 of the disassembly plate 315 is 1:2. During the down-pressing process, the lifting end 3153 is lifted to a relatively large height, which is beneficial for the user to pull upwards with force.

In some embodiments, a reinforcing rib 314 is arranged between the hinge block 313 and the bottom of the disassembly groove 312, and is used for fixing the hinge block 313. The reinforcing rib 314 is arranged directly below the down-pressing end 3152. In a process of down pressing the down-pressing end 3152, the down-pressing end 3152 abuts against the reinforcing rib 314, and the reinforcing rib 314 can play a role in limiting the down-pressing end 3152, so as to limit an amplitude of downward rotation of the down-pressing end 3152. If the amplitude of the down-pressing end 3152 is not limited, when a rotation angle of the lifting end 3153 is relatively large, such as 80°, it is not beneficial for the user to apply upward force for pulling. The rotation angle of the disassembly plate 315 is in a range from 20° to 60°, and the rotation angle of the disassembly plate 315 can be limited by arranging a height of the reinforcing rib 314.

As shown in FIG. 11 to FIG. 14, in some other embodiments, a first down-pressing protruding element 3161 extending towards the fixing ring 343 is arranged on a lower surface of the first fixing plate 311, and an end of the first down-pressing protruding element 3161 is able to abut against the fixing ring 343. When the first fixing plate 311 is pressed down, the first fixing plate 311 presses the fixing ring 343 down by pressing the first down-pressing protruding element 3161 down, causing the fixing ring 343 to move downward.

In some embodiments, the first down-pressing protruding element 3161 is provided with a down-pressing groove 3162 in a surface close to the fixing ring 343, a limiting protrusion part 3163 extending towards the first down-pressing protruding element 3161 is arranged at a position where the fixing ring 343 is adapted to the down-pressing groove 3162, and the limiting protrusion part 3163 is accommodated in the down-pressing groove 3162. By arranging the down-pressing groove 3162 and the limiting protrusion part 3163, a 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 down-pressing process.

In some embodiments, the disassembly-installation assembly 31 includes a lifting assembly 317. The lifting assembly 317 includes a first lifting element 3171 extending towards the fixing ring 343 and arranged on a lower surface of the first fixing plate 311, and a second lifting element 3173 extending towards the first fixing plate 311 and arranged on the fixing ring 343. A first protrusion part 3172 extending towards the second lifting element 3173 is arranged at an end of the first lifting element 3171, a second protrusion part 3174 extending towards the first lifting element 3171 is arranged at an end of the second lifting element 3173, and an upper surface of the first protrusion part 3172 and a lower surface of the second protrusion part 3174 are arranged in a fit manner. When the filtering mechanism 3 is disassembled, by upward pulling the first fixing plate 311, and then upward pulling the fixing ring 343 through the first lifting element 3171, the first protrusion part 3172, the second protrusion part 3174, and the second lifting element 3173, the filtering mechanism 3 can be taken out.

In some embodiments, two groups of lifting assemblies 317 are symmetrically arranged on left and right sides of the limiting protrusion part 3163, so as to ensure that the fixing ring 343 is uniformly stressed during the upward pulling process, making it easy to take out the fixing ring 343.

In some embodiments, a second down-pressing protruding element 318 is arranged on a lower side surface of the fixing ring 343, and the second down-pressing protruding element 318 is fixedly connected to the lower side surface of the fixing ring 343. The fixing ring 343 drives the second down-pressing protruding element 318 to move up and down. A bouncing device 319 is arranged at a bottom of the installation groove 131, and the bouncing device 319 is located directly below the second down-pressing protruding element 318. The second down-pressing protruding element 318 is able to, when moving downwards, extrude the bouncing device 319, so that the bouncing device 319 bounces and applies an upward supporting force to the fixing ring 343, causing the fixing ring 343 to move upward. That is, the filtering mechanism 3 bounces upward from the interior of the installation groove 131, and the user can directly take out the filtering mechanism 3 upwards.

The filtering mechanism 3 is convenient to disassemble and install. When taking out, only the first fixing plate 311 is pressed down, the filtering mechanism 3 bounces upward from the installation groove 131, and the user can directly take out the filtering mechanism 3. During installation, the first fixing plate 311 is directly extruded downward to accommodate the filtering mechanism 3 in the installation groove 131. Use of the user is facilitated, and the user experience is enhanced.

During use of the user, in a process of disassembling and installing the filtering mechanism 3 from the vacuum cleaner, the user holds a machine body with one hand and only needs to disassemble the filtering mechanism 3 with the other hand. The process is very short and the user is very labor-saving. Afterwards, the user may put down the machine body, take the compact filtering mechanism 3 to a cleaning position, and easily disassemble the filtering mechanism 3 to take out the filtering assembly 34 for clearing. After clearing, the filtering assembly 34 is installed back into the fixing ring 343 of the filtering mechanism 3, then the filtering mechanism 3 is taken back to the machine body, the user holds the machine body with one hand and only needs to install the filtering mechanism 3 back into the machine body with the other hand. The operation is very fast and labor-saving.

As shown in FIG. 2 and FIG. 15 to FIG. 18, in some embodiments, the dust collecting mechanism 2 includes a dust cup, a partition element 25 is arranged in the dust cup to divide the dust cup into a first dust cup 23 and a second dust cup 24, and a dust outlet 251 is formed in the partition element 25. Gas, dust, and garbage in the first dust cup 23 may enter the second dust cup 24 from the first dust cup 23 with the airflow. As the gas entering the second dust cup 24 increases, the gas in the second dust cup 24 can overflow through the dust outlet 251 and enter the first dust cup 23. Under the action of the motor 5, the gas is filtered by the filtering mechanism 3 and flows out from an air outlet located at a rear end of the vacuum cleaner.

In some embodiments, the dust collecting mechanism 2 includes an air inlet channel 21, and the air inlet channel 21 is formed in a front end of the vacuum cleaner. A spiral channel 22 is formed in a rear end of the air inlet channel 21. The first dust cup 23 is in fluid communication with the spiral channel 22. After air enters the spiral channel 22 through the air inlet channel 21, the air forms cyclone and enters the first dust cup 23. The airflow entering the first dust cup 23 may be subjected to cyclone separation, and the dust subjected to cyclone separation in the first dust cup 23 may enter the second dust cup 24 through the dust outlet 251.

During normal use, about 90% of the dust may enter the second dust cup 24 through the dust outlet 251. Even if a small amount of dust remains in the first dust cup 23, when the vacuum cleaner is used again, the dust will be subjected to cyclone separation again and enter the second dust cup 24. Therefore, during normal use, only the second dust cup 24 needs to be cleaned.

A dust removal cover 241 is arranged at a front end of the second dust cup 24, and is hinged to a second dust cup body 242. When the dust inside the second dust cup 24 needs to be cleared, only the dust removal cover 241 needs to be opened to pour the dust out, without the need to disassemble the second dust cup 24, making it extremely convenient to treat the dust or garbage inside the second dust cup 24. That is to say, by arranging the second dust cup 24, it is convenient for the user to clear the dust collected inside the vacuum cleaner.

In some embodiments, a lower side wall 12 of the housing 1 is integrally connected with the partition element 25 to form a second dust cup 24, thereby improving the sealing performance of the second dust cup 24. An upper side wall 11 of the housing 1 is in clamped connection with the partition element 25 to form the first dust cup 23. The first dust cup 23 and the second dust cup 24 share the partition element 25, thereby making the structure of the vacuum cleaner more compact and lightweight, and improving the user experience.

In some embodiments, a metal mesh 26 is arranged in a cavity of the first dust cup 23, and the metal mesh 26 is arranged directly above the dust outlet 251. The metal mesh 26 is of a circular truncated cone structure or a conical structure, and is arranged to protrude towards the front end of the vacuum cleaner. By arranging the metal mesh 26, large particles of dust or garbage can be blocked and enter the second dust cup 24.

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 to be a cleaning module, and the cleaning module is detachably connected to the vacuum cleaner body through 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 together with the metal mesh 26 can be taken down as a whole, and the bottom of the first dust cup 23 (the upper side surface of the partition element 25), the metal mesh 26, and the second dust cup 24 are cleared together, making it convenient for the user to perform deep cleaning on the vacuum cleaner.

In some embodiments, the connecting mechanism 4 is arranged between the installation part 13 and the dust collecting mechanism 2, and the connecting mechanism 4 is fixedly connected to the rear end of the dust collecting mechanism 2. The connecting mechanism 4 includes a button 41 as a portion of the appearance surface, and a clamping protrusion part 42 connected to the button 41. The clamping protrusion part 42 can expand and contract in a second direction (left-right direction) with the button 41. A second clamping groove 44 is formed in a corresponding position on the inner side surface of the installation part 13. The clamping protrusion part 42 can be accommodated in the second clamping groove 44, thereby connecting the installation part 13 with the dust collecting mechanism 2.

In some embodiments, the connecting mechanism 4 includes a positioning protrusion part 43 extending towards the installation part 13, and a positioning chute 45 is formed in the corresponding position on the inner side surface of the installation part 13. In a process of installing the dust collecting mechanism 2, the positioning protrusion part 43 slides along the positioning chute 45 to ensure that the clamping protrusion part 42 can be accommodated in the second clamping groove 44, thereby improving the convenience of installation.

In some embodiments, a first partition plate 14 and a second partition plate 15 are arranged 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 partition element 25. The connecting mechanism 4 further includes a first clamping element 46 arranged on the first partition plate 14, and a second clamping element 47 arranged at a corresponding position of the second partition plate 15. The first clamping element 46 and the second clamping element 47 can be in clamped connection with each other, so that the front ends of the first dust cup 23 and the second dust cup 24 are fixedly connected.

By arranging the first clamping element 46 and the second clamping element 47 at the front end of the vacuum cleaner to fix the second dust cup 24, and by arranging the clamping protrusion part 42 and the second clamping groove 44 to fix the other end of the second dust cup 24, the second dust cup 24 together with the metal mesh 26 are integrally installed on the vacuum cleaner, making it convenient for the user to remove the first dust cup, the second dust cup, and the metal mesh for performing deep cleaning on the vacuum cleaner.
