Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and more specifically, to a vacuum cleaner. Background Technology

[0002] A vacuum cleaner is a household cleaning device that uses negative pressure suction to remove dust, debris, and other impurities. With its high cleaning efficiency and ease of use, it is widely used for daily cleaning in homes, offices, and various small spaces. Current vacuum cleaners typically consist of a main body, a suction power unit, a dust collection structure, and a filtration structure. The suction power source generates negative pressure airflow, drawing external debris into the dust collection structure. The filtration structure then separates the air from the dust, and clean air is finally discharged from the outlet, thus achieving environmental cleanliness.

[0003] However, the disassembly of the dust collection structure and the cleaning of the filter structure in the vacuum cleaners of related technologies are quite cumbersome. They usually require tools or multiple disassembly steps to complete. In addition, the complex air duct layout leads to high airflow resistance and a bulky overall structure, which further increases the difficulty and time cost of daily maintenance and reduces the user experience. Utility Model Content

[0015] The anti-rotation component is located on the opposite side of the connection between the machine body and the dust collection bin, and is used to limit the dust collection bin from deflecting relative to the machine body when the locking component is locked.

[0016] The locking component and the anti-rotation component are arranged opposite each other along the circumference of the dust collection bin.

[0017] Optionally, the locking assembly includes a locking groove, a locking block, a locking button, and a resilient reset member;

[0018] The locking groove is provided on the inner peripheral wall of the dust collection bin;

[0021] A positioning groove is provided on the inner peripheral wall of the dust collection bin, and the positioning groove and the locking groove are arranged opposite to each other along the circumference of the dust collection bin;

[0022] A positioning protrusion is disposed on the outer surface of the body and adapted to the positioning groove. The positioning protrusion and the locking block are disposed opposite to each other along the circumference of the body.

[0023] Optionally, the dust collection chamber has a mounting ring coaxially provided on the inner peripheral wall of one end near the suction port, and the inner periphery of the mounting ring extends axially away from the suction port to form a mounting sleeve; the filter device is sleeved on the outer periphery of the mounting sleeve, and a fixing component is provided between the mounting ring and the filter device for detachably fixing the filter device to the mounting ring.

[0024] Optionally, the filtration device includes a pressure sleeve, a filter bag, and a filter cup arranged concentrically from the inside to the outside. The openings of the pressure sleeve, the filter bag, and the filter cup all face the inlet. The pressure sleeve is used to press the filter bag tightly inside the filter cup.

[0025] The pressure sleeve is interference-fitted onto the outer periphery of the mounting sleeve;

[0026] The filter cup has a filter screen on its side wall, and the mesh size of the filter screen is larger than that of the filter bag.

[0032] The beneficial effects of this vacuum cleaner are as follows: When the vacuum cleaner is working, the suction power source is activated, generating negative pressure at the suction port. The dust-laden airflow from the outside enters the dust collection chamber through the suction port, passes through the filter device and the suction port located on the same axis in a straight line, and then enters the interior of the machine body. Finally, it is discharged from the air outlet. Dust and debris are intercepted and retained in the dust collection chamber when passing through the filter device, thus completing the separation and collection of air and dust.

[0033] By arranging the suction port, filter, and intake port along the same axis, the airflow path is straight and unobstructed, effectively shortening the duct length, reducing airflow resistance, and making the overall structure more compact. At the same time, the dust collection chamber is detachably installed on the machine body through a locking mechanism, and the filter is detachably installed inside the dust collection chamber. Users can quickly disassemble the dust collection chamber and clean or replace the filter without the need for tools, which significantly reduces the difficulty and time cost of daily maintenance and improves the user experience.

[0044] like Figure 1 , Figure 2 , Figure 3 As shown in the figure, a vacuum cleaner provided in this embodiment of the present utility model includes: a body 1, one end of which is provided with an inlet 11, and an outlet 12 is also provided on the body 1;

[0045] The dust collection chamber 2 is detachably installed on the end of the machine body 1 that has a suction port 11 via a locking mechanism 5, and the end of the dust collection chamber 2 away from the machine body 1 has a dust suction port 21;

[0046] The filter device 3 is detachably installed inside the dust collection chamber 2 and is located between the dust inlet 21 and the suction inlet 11;

[0047] The suction power source 4 is located inside the body 1 and on the side of the suction port 11 away from the dust collection chamber 2. It is used to draw air in from the suction port 11 and discharge it through the air outlet 12.

[0048] The suction port 21, the filter device 3, and the suction port 11 are arranged sequentially along the same axis.

[0049] Specifically, the main body 1 serves as the overall supporting structure, with an intake port 11 at one end that connects to the dust collection chamber 2, and an air outlet 12 on the side wall of the main body 1. A suction power source 4 is fixedly installed inside the main body 1 and located behind the intake port 11, providing negative pressure for the entire airflow channel. The dust collection chamber 2 is detachably installed at the end of the main body 1 with the intake port 11 via a locking mechanism 5. A dust suction port 21 is located at the end of the dust collection chamber 2 furthest from the main body 1, through which dust-laden airflow enters the equipment. A filter device 3 is detachably installed inside the dust collection chamber 2, located between the dust suction port 21 and the intake port 11, to intercept dust and debris in the airflow.

[0050] After the suction power source 4 is started, a negative pressure is generated at the suction port 21. Outside dust-laden air is drawn into the dust collection chamber 2 through the suction port 21, passes through the filter device 3 and the suction port 11 located on the same axis in a straight line, and then enters the body 1. Finally, it is discharged from the air outlet 12. When the dust-laden air passes through the filter device 3, dust and debris are intercepted and retained in the dust collection chamber 2, completing the air-dust separation and collection.

[0051] Specifically, in this embodiment, the suction power source 4 includes a motor and an impeller. The output end of the motor is connected to the impeller, which is located on the side near the suction port 11. After the motor starts, it drives the impeller to rotate, and the impeller draws air in from the suction port 11 and discharges it through the air outlet 12. A connector for connecting the battery pack is provided on the rear side of the body 1. The connector is electrically connected to both the battery pack and the motor. A handle structure is integrally formed on the rear side of the body 1 for easy gripping and operation by the user.

[0052] In this embodiment, by arranging the dust inlet 21, the filter device 3, and the suction inlet 11 along the same axis, the airflow path is straight and unobstructed, effectively shortening the duct length, reducing airflow resistance, and simplifying the internal structure of the entire machine. Simultaneously, the dust collection chamber 2 is detachably mounted to the body 1 via the locking mechanism 5, and the filter device 3 is detachably located inside the dust collection chamber 2. Users can quickly disassemble the dust collection chamber 2 and clean or replace the filter device 3 without the need for tools, significantly reducing the difficulty and time cost of daily maintenance and improving the user experience.

[0053] Optionally, such as Figure 2 , Figure 3 As shown, the dust collection chamber 2 is provided with a baffle plate 22 inside one side of the dust suction port 21. The baffle plate 22 can rotate unidirectionally toward the inside of the dust collection chamber 2 to prevent dust in the dust collection chamber 2 from escaping out through the dust suction port 21.

[0054] Specifically, a baffle plate 22 is provided inside the dust collection chamber 2 near the dust suction port 21. One end of the baffle plate 22 is pivotally connected to the inner wall of the dust collection chamber 2, and the other side of the baffle plate 22 is a free end, which can rotate freely in the direction towards the inside of the dust collection chamber 2.

[0055] The initial state of the baffle plate 22 is to close the dust inlet 21. When the suction power source 4 is working, the negative pressure generated by it acts on the surface of the baffle plate 22 facing the dust inlet 21, causing the baffle plate 22 to rotate and open towards the dust collection chamber 2 against its own gravity, and the dust-laden air enters the dust collection chamber 2 through the dust inlet 21. When the suction power source 4 stops working, the negative pressure disappears, and the baffle plate 22 automatically rotates back to the initial position of closing the dust inlet 21 by its own gravity, preventing the dust in the dust collection chamber 2 from overflowing out through the dust inlet 21.

[0056] Specifically, in this embodiment, the wind deflector 22 can be a flexible deflector. The top end of the flexible deflector is connected to the inner wall of the dust collection chamber 2 by fasteners, and the other end of the flexible deflector is a free end that can swing freely.

[0057] In this optional embodiment, by setting a baffle 22 that can rotate unidirectionally toward the inside of the dust collection chamber 2, the vacuum cleaner can automatically close the suction port 21 after it stops working, effectively preventing the dust in the dust collection chamber 2 from flowing back into the outside environment, avoiding secondary dust pollution and dirt around the suction port 21, and improving the hygiene of the equipment after it stops and the user's experience.

[0058] Optionally, such as Figure 3 As shown, the air outlet 12 is located on the side wall of the body 1, and there are multiple air outlets 12, which are distributed at intervals along the circumference of the body 1.

[0059] Specifically, the suction power source 4 guides the filtered clean air through the flow channel inside the body 1 to the air outlet 12. The airflow is simultaneously and evenly discharged outward through multiple air outlets 12 distributed circumferentially on the side wall of the body 1. The multi-outlet diversion structure helps to reduce the exhaust speed of a unit air outlet, reduce exhaust noise, and complete the airflow circulation of the whole machine.

[0060] In this optional embodiment, by setting multiple air outlets 12 on the side wall of the body 1 and distributing them at intervals along the circumference, the exhaust airflow is evenly diffused in multiple directions, avoiding the problem of airflow being concentrated and blown towards the user or surrounding objects due to the traditional single air outlet structure at the rear, thus improving user comfort and safety.

[0061] Optionally, such as Figure 2 As shown, the locking mechanism 5 includes a locking component 51 and an anti-rotation component 52:

[0062] The locking component 51 is located on one side of the connection between the body 1 and the dust collection chamber 2, and is used to lock the dust collection chamber 2 onto the body 1 in an unlockable manner;

[0063] The anti-rotation component 52 is located on the opposite side of the connection between the body 1 and the dust collection chamber 2, and is used to limit the dust collection chamber 2 from deflecting relative to the body 1 when the locking component 51 is locked;

[0064] The locking component 51 and the anti-rotation component 52 are arranged opposite each other along the circumference of the dust collection bin 2.

[0065] Specifically, the locking mechanism 5 consists of a locking component 51 and an anti-rotation component 52, respectively disposed on opposite sides of the connection between the body 1 and the dust collection chamber 2. The locking component 51, as the active operating end, is disposed on one side of the connection to achieve unlockable locking between the dust collection chamber 2 and the body 1. The anti-rotation component 52, as the passive cooperating end, is disposed on the opposite side of the connection to provide auxiliary constraint when the locking component 51 is locked, preventing the dust collection chamber 2 from deflecting relative to the body 1. The locking component 51 and the anti-rotation component 52 are disposed opposite each other along the circumference of the dust collection chamber 2, that is, they form approximately a 180° angle in the circumferential direction at the connection, forming two mutually cooperating constraint points that jointly limit the circumferential deflection and axial displacement of the dust collection chamber 2 relative to the body 1, ensuring that the dust collection chamber 2 is stable and does not shake when locked.

[0066] During installation, the anti-rotation component 52 engages first, providing circumferential positioning and installation guidance for the dust collection chamber 2, ensuring accurate alignment of the locking component 51. After the dust collection chamber 2 is pushed into place, the locking component 51 locks in place. During disassembly, the user must first operate the locking component 51 to unlock it, and then operate the anti-rotation component 52 to disengage it, allowing the dust collection chamber 2 to be pulled out.

[0067] In this optional embodiment, the locking component 51 and the anti-rotation component 52 are arranged opposite each other along the circumference of the dust collection chamber 2, forming a two-point constraint structure at the connection between the body 1 and the dust collection chamber 2. The locking component 51 provides active locking, and the anti-rotation component 52 provides auxiliary constraint on the opposite side, effectively preventing the dust collection chamber 2 from deflecting or loosening due to vibration or external force during use. At the same time, the anti-rotation component 52 provides circumferential positioning guidance during installation, ensuring that the locking component 51 is quickly and accurately aligned, making the installation process smoother and improving the convenience of user operation and user experience.

[0068] Optionally, such as Figure 2 As shown, the locking assembly 51 includes a locking groove 511, a locking block 512, a locking button 513, and a resilient reset member 514;

[0069] The locking groove 511 is provided on the inner peripheral wall of the dust collection bin 2;

[0070] The body 1 is provided with a mounting groove 13. The locking button 513 is located in the mounting groove 13 and extends out of the outer surface of the body 1. The locking block 512 is connected to one end of the locking button 513 and is adapted to the locking groove 511. The elastic reset member 514 is located in the mounting groove 13 and is connected between the locking button 513 and the groove wall of the mounting groove 13, and is used to drive the locking block 512 to reset to the state of engaging with the locking groove 511.

[0071] Specifically, a locking groove 511 is formed at a predetermined position on the inner peripheral wall of the dust collection chamber 2, for engaging with the locking block 512. The body 1 has a mounting groove 13, and a locking button 513 is disposed within the mounting groove 13. Its operating end extends out of the outer surface of the body 1 for user pressing, and its other end is connected to the locking block 512. The locking block 512 is shaped to match the locking groove 511. When the locking block 512 engages with the locking groove 511, the dust collection chamber 2 is locked to the body 1; when the locking block 512 disengages from the locking groove 511, the lock is released. An elastic reset member 514 is disposed within the mounting groove 13, one end connected to the locking button 513, and the other end connected to the groove wall of the mounting groove 13, constantly applying an elastic force towards the locking groove 511 to the locking button 513.

[0072] When installing the dust collection chamber 2, the inner circumferential wall of the dust collection chamber 2 presses against the locking block 512 to prevent it from moving out of the way. After the dust collection chamber 2 is pushed into place, the elastic reset member 514 drives the locking button 513, causing the locking block 512 to automatically engage with the locking groove 511, thus completing the locking. For disassembly, the user presses the locking button 513, compressing the elastic reset member 514. The locking button 513 then causes the locking block 512 to disengage from the locking groove 511, thereby releasing the lock and allowing the dust collection chamber 2 to be pulled out. After releasing the locking button 513, the elastic reset member 514 drives the locking button 513 to reset, keeping the locking block 512 in an extended state, ready to automatically engage with the locking groove 511 during the next installation.

[0073] In this optional embodiment, the automatic locking during installation and the one-button unlocking during disassembly of the dust collection chamber 2 are achieved through the coordinated operation of the locking button 513, the elastic reset component 514, and the locking block 512. Users can quickly complete the installation and disassembly of the dust collection chamber 2 without the need for any tools, significantly reducing the difficulty and time cost of daily maintenance. At the same time, the locking component 51 has a compact overall layout, integrated at the connection between the body 1 and the dust collection chamber 2, without occupying additional air duct space, which is beneficial for the miniaturization of the entire unit.

[0074] Optionally, such as Figure 2 As shown, the anti-rotation component 52 includes:

[0075] The positioning groove 521 is provided on the inner peripheral wall of the dust collection chamber 2, and the positioning groove 521 and the locking groove 511 are arranged opposite to each other along the circumference of the dust collection chamber 2.

[0076] The positioning protrusion 522 is disposed on the outer surface of the body 1 and is adapted to the positioning groove 521. The positioning protrusion 522 and the locking block 512 are disposed opposite to each other along the circumference of the body 1.

[0077] Specifically, the anti-rotation component 52 includes a positioning groove 521 and a positioning protrusion 522. The positioning groove 521 is located at a predetermined position on the inner peripheral wall of the dust collection chamber 2, and the positioning protrusion 522 is located at a corresponding position on the outer surface of the body 1. The shape of the positioning protrusion 522 is adapted to the positioning groove 521, and the two are inserted into each other. The positioning groove 521 and the locking groove 511 are arranged opposite each other along the circumference of the dust collection chamber 2, that is, the two are basically at a 180° angle on the inner peripheral wall of the dust collection chamber 2; the positioning protrusion 522 and the locking block 512 are arranged opposite each other along the circumference of the body 1, that is, the two are basically at a 180° angle on the outer surface of the body 1.

[0078] When installing the dust collection bin 2, the positioning protrusion 522 is first aligned and inserted into the positioning groove 521, providing installation guidance for the dust collection bin 2 and restricting its circumferential rotation, so that the locking groove 511 and the locking block 512 are accurately aligned. After the dust collection bin 2 is pushed into place, the locking block 512 is locked into the locking groove 511 under the action of the elastic reset member 514. At this time, the anti-rotation component 52 and the locking component 51 form a two-point circumferential constraint on opposite sides of the connection between the machine body 1 and the dust collection bin 2, which together restricts the circumferential deflection and radial displacement of the dust collection bin 2 relative to the machine body 1. During disassembly, the user presses the locking button 513 to disengage the locking block 512 from the locking groove 511, and then pulls the dust collection bin 2 out axially. The positioning protrusion 522 slides out of the positioning groove 521, the constraint of the anti-rotation component 52 is released, and the dust collection bin 2 can be removed from the machine body 1.

[0079] In this optional embodiment, the positioning groove 521 and the locking groove 511 are arranged opposite each other along the circumference of the dust collection chamber 2, and the positioning protrusion 522 and the locking block 512 are arranged opposite each other along the circumference of the machine body 1. This forms a two-point circumferential constraint between the anti-rotation component 52 and the locking component 51 on opposite sides of the connection between the machine body 1 and the dust collection chamber 2, effectively preventing the dust collection chamber 2 from deflecting or loosening due to vibration or external force during use. At the same time, the insertion and engagement of the positioning protrusion 522 and the positioning groove 521 provides circumferential positioning and installation guidance during installation, ensuring that the locking component 51 is quickly and accurately aligned, making the disassembly and assembly process smoother and more reliable.

[0080] Optionally, such as Figure 3 , Figure 4 , Figure 5 As shown, a mounting ring 23 is coaxially provided on the inner peripheral wall of the dust collection chamber 2 near the suction port 11. The inner periphery of the mounting ring 23 extends axially away from the suction port 11 to form a mounting sleeve 24. The filter device 3 is sleeved on the outer periphery of the mounting sleeve 24. A fixing component 6 is provided between the mounting ring 23 and the filter device 3 for detachably fixing the filter device 3 to the mounting ring 23.

[0081] Specifically, at one end of the dust collection chamber 2 near the suction inlet 11, an mounting ring 23 is coaxially connected to its inner peripheral wall. The mounting ring 23 has a ring-shaped structure and is arranged coaxially with the dust collection chamber 2. The outer peripheral edge of the mounting ring 23 seals against the inner peripheral wall of the dust collection chamber 2, and the inner peripheral edge of the mounting ring 23 extends axially away from the suction inlet 11 to form a mounting sleeve 24. The mounting sleeve 24 has a cylindrical structure, and its inner hole connects the dust collection chamber 2 and the suction inlet 11, forming a channel for clean air to pass through.

[0082] The filter device 3 is fully fitted onto the outer periphery of the mounting sleeve 24, allowing the air outlet side of the filter device 3 to communicate with the suction port 11 through the inner hole of the mounting sleeve 24. A fixing component 6 is provided between the mounting ring 23 and the filter device 3. This fixing component 6 is used to detachably fix the filter device 3 to the mounting ring 23, and to securely hold the filter device 3 in a predetermined position within the dust collection chamber 2 when the vacuum cleaner is working, preventing the filter device 3 from shifting due to airflow impact or vibration.

[0083] When installing the filter device 3, the filter device 3 is fitted onto the outer periphery of the mounting sleeve 24, forming a fitting between the filter device 3 and the mounting sleeve 24. The filter device 3 is then fixed to the mounting ring 23 by the fixing component 6. During operation, the dust-laden airflow enters the dust collection chamber 2 through the dust inlet 21, passes through the filter device 3 to complete air-dust separation, and the separated clean air is drawn in and discharged by the suction power source 4 through the inner hole of the mounting sleeve 24 and the suction inlet 11. Dust and debris are intercepted by the filter device 3 and retained in the dust collection chamber 2.

[0084] Preferably, the inner peripheral wall of the dust collection chamber 2 is provided with multiple support columns at intervals, and the end face of the mounting ring 23 away from the suction port 11 abuts against one end of the support column, with the support column providing axial support for the mounting ring 23. The outer periphery of the mounting ring 23 is interference-fitted with the inner peripheral wall of the dust collection chamber 2.

[0085] Preferably, the mounting sleeve 24 and the mounting ring 23 are integrally formed.

[0086] Preferably, the outer peripheral edge of the mounting ring 23 is provided with a sealing ring, and the mounting ring 23 is sealed against the inner peripheral wall of the dust collection chamber 2 through the sealing ring.

[0087] Preferably, the mounting ring 23 is provided with a sealing gasket on the side near the suction port 11, for sealing and abutting against the end face of the body 1 after the filter device 3 is installed.

[0088] In this optional embodiment, by setting an installation ring 23 and an installation sleeve 24 inside the dust collection chamber 2, the filter device 3 can be quickly installed on the outer periphery of the installation sleeve 24 by means of a sleeve connection, and is detachably fixed to the installation ring 23 by the fixing component 6. The user can remove the filter device 3 from the dust collection chamber 2 as a whole for cleaning or replacement without the aid of tools, realizing convenient maintenance of the filter device 3, while ensuring the installation stability and airflow sealing of the filter device 3 in the dust collection chamber 2.

[0089] Optionally, such as Figure 4 , Figure 5 As shown, the filter device 3 includes a pressure sleeve 31, a filter bag 32 and a filter cup 33 arranged concentrically from the inside to the outside. The openings of the pressure sleeve 31, the filter bag 32 and the filter cup 33 all face the inlet 11. The pressure sleeve 31 is used to press the filter bag 32 into the filter cup 33.

[0090] The pressure sleeve 31 is interference-fitted onto the outer periphery of the mounting sleeve 24;

[0091] A filter screen is provided on the side wall of the filter cup 33, and the mesh size of the filter screen is larger than that of the filter bag 32.

[0092] Specifically, the filter device 3 is composed of a pressure sleeve 31, a filter bag 32, and a filter cup 33, which are concentrically arranged from the inside to the outside. The pressure sleeve 31, the filter bag 32, and the filter cup 33 are all cylindrical structures with one open end and one closed end, and the open ends of all three face the suction port 11. The filter bag 32 is fitted around the outer periphery of the pressure sleeve 31, and the filter cup 33 is fitted around the outer periphery of the filter bag 32. The pressure sleeve 31 presses the filter bag 32 tightly against the inner wall of the filter cup 33, so that the filter bag 32 is flat and fits against the inner wall of the filter cup 33.

[0093] A filter screen is provided on the side wall of the filter cup 33, and the filter bag 32 is a filter material with micropores. The mesh size of the filter screen is larger than that of the filter bag 32. After the dust-laden airflow enters the dust collection chamber 2 through the suction port 21, it first passes through the filter screen on the side wall of the filter cup 33. Large particles are intercepted on the outside of the filter screen. The dust-laden airflow then passes through the filter bag 32, where small particles are intercepted on the outer surface of the filter bag 32. The clean air after two stages of filtration enters the pressure sleeve 31, and is sucked in by the suction power source 4 through the inner hole of the mounting sleeve 24 and the suction port 11. Finally, it is discharged through the air outlet 12.

[0094] The pressure sleeve 31 is interference-fitted onto the outer periphery of the mounting sleeve 24, meaning the inner diameter of the pressure sleeve 31 is smaller than the outer diameter of the mounting sleeve 24. This interference fit secures the pressure sleeve 31 to the outer periphery of the mounting sleeve 24, eliminating the need for additional connectors and facilitating its disassembly. The interference fit between the pressure sleeve 31 and the mounting sleeve 24 creates a tight, gapless fit, sealing any assembly seams and preventing unfiltered airflow from the inside of the filter device 3 directly into the inner hole of the mounting sleeve 24. Simultaneously, the pressure sleeve 31 presses the filter bag 32 firmly against the inner wall of the filter cup 33, ensuring the filter bag 32 lies flat and conforms to the inner wall of the filter cup 33. This prevents the filter bag 32 from shifting, wrinkling, or piling up due to airflow impact during use, thus guaranteeing the effective filtration area of ​​the filter bag 32.

[0095] During installation, the pressure sleeve 31, filter bag 32, and filter cup 33 are concentrically fitted from the inside out, with all three openings facing the suction port 11. The pressure sleeve 31 presses the filter bag 32 tightly against the inner wall of the filter cup 33, and then the pressure sleeve 31 is interference-fitted onto the outer periphery of the mounting sleeve 24. During operation, the dust-laden airflow enters through the suction port 21, first undergoes coarse filtration through the filter screen on the side wall of the filter cup 33 to intercept large particles, and then undergoes fine filtration through the filter bag 32 to intercept small particles. The clean air after two stages of filtration enters the interior of the pressure sleeve 31, and is then sucked in and discharged by the suction power source 4 through the inner hole of the mounting sleeve 24 and the suction port 11.

[0096] In this optional embodiment, the dust-laden airflow first undergoes coarse filtration through the filter screen on the side wall of the filter cup 33, and then undergoes fine filtration through the filter bag 32, forming a two-stage filtration path from the outside to the inside and from coarse to fine. This effectively improves the filtration efficiency and dust-air separation effect, and extends the service life of the filter bag 32. At the same time, the pressure sleeve 31 presses the filter bag 32 tightly against the inner wall of the filter cup 33, ensuring the stable positioning of the filter bag 32 within the filter cup 33. Furthermore, the pressure sleeve 31 is interference-fitted with the outer periphery of the mounting sleeve 24, allowing for quick fixing and disassembly of the pressure sleeve 31 without additional connecting parts, further enhancing the ease of disassembly, assembly, and maintenance of the filtration device 3.

[0097] Optionally, such as Figure 4 , Figure 5 As shown, the fixing component 6 includes a fixing block 61 and a fixing groove 63:

[0098] At least two fixing blocks 61 are provided on the outer periphery of the filter cup 33 near its opening, and the at least two fixing blocks 61 are distributed at intervals along the circumference of the filter cup 33.

[0099] At least two fixing seats 62 are provided at circumferential intervals on the mounting ring 23. Each fixing seat 62 is provided with a fixing groove 63. The fixing groove 63 has an opening for the fixing block 61 to be screwed into the mounting ring 23 circumferentially, and the fixing groove 63 is closed at the rear end along the screwing direction.

[0100] The fixing block 61 corresponds to and is adapted to the fixing groove 63. The fixing block 61 is engaged in the corresponding fixing groove 63 to restrict the filter cup 33 from moving axially relative to the mounting ring 23.

[0101] Specifically, at least two fixing blocks 61 are provided on the outer periphery of the filter cup 33 near its opening. Multiple fixing blocks 61 are spaced apart circumferentially along the filter cup 33, each protruding outward from the outer peripheral wall of the filter cup 33. At least two fixing seats 62 are spaced apart circumferentially on the mounting ring 23. The number of fixing seats 62 is the same as the number of fixing blocks 61, and their positions correspond one-to-one. Each fixing seat 62 has a fixing groove 63. The fixing groove 63 has an opening circumferentially along the mounting ring 23, allowing the fixing block 61 to be screwed into the fixing groove 63 circumferentially from the opening. The fixing groove 63 is closed at its rear end along the screwing direction, forming a limiting baffle to prevent the fixing block 61 from continuing to rotate and coming out after being screwed in. The shapes of the fixing block 61 and the fixing groove 63 are adapted to each other. When the fixing block 61 is screwed into the corresponding fixing groove 63, the fixing block 61 and the fixing groove 63 engage. The fixing groove 63 forms an axial limit on the fixing block 61, restricting the filter cup 33 from moving axially relative to the mounting ring 23.

[0102] When installing the filter cup 33, the pressure sleeve 31 is fitted onto the outer periphery of the mounting sleeve 24, so that the fixing block 61 on the outer periphery of the filter cup 33 is aligned with the opening of the fixing groove 63 of the fixing seat 62 on the mounting ring 23. The filter cup 33 is rotated circumferentially along the mounting ring 23, and the fixing block 61 is screwed into the fixing groove 63 from the opening until it abuts against the closed rear end of the fixing groove 63, thereby achieving axial positioning of the filter cup 33 on the mounting ring 23. When disassembling, the filter cup 33 is rotated in the opposite direction, so that the fixing block 61 is screwed out from the opening of the fixing groove 63, and the filter cup 33 can be removed from the mounting ring 23.

[0103] In this optional embodiment, the screw-in engagement of the fixing block 61 and the fixing groove 63 enables quick and detachable fixing between the filter cup 33 and the mounting ring 23. Users only need to rotate the filter cup 33 to complete the installation or removal without any tools, significantly improving the ease of maintenance of the filter device 3. The fixing groove 63 is closed at its rear end along the screw-in direction to prevent the fixing block 61 from dislodging after screwing in, ensuring that the filter cup 33 will not accidentally loosen due to vibration or external force during use, thus enhancing the stability and reliability of the connection. Furthermore, the one-to-one circumferential engagement of multiple fixing blocks 61 and fixing grooves 63 ensures uniform circumferential force on the filter cup 33, further improving the stability of the filter cup 33 within the dust collection chamber 2.

[0104] Optionally, such as Figure 4 , Figure 5 As shown, the pressure sleeve 31 includes a pressure ring 311 and a plurality of pressure rods 312. The plurality of pressure rods 312 are distributed at intervals along the circumference of the pressure ring 311 on one side of the pressure ring 311. The pressure ring 311 is sleeved on the outer periphery of the mounting sleeve 24. One end of the pressure rod 312 connected to the pressure ring 311 abuts against the end of the mounting sleeve 24. The pressure rod 312 extends axially away from the suction port 11.

[0105] Specifically, the pressure sleeve 31 consists of a pressure ring 311 and multiple pressure rods 312. The pressure ring 311 is an annular structure, and its inner diameter is adapted to the outer diameter of the mounting sleeve 24. The pressure ring 311 is fitted around the outer circumference of the mounting sleeve 24 to achieve radial positioning of the pressure sleeve 31 on the mounting sleeve 24. The multiple pressure rods 312 are evenly distributed circumferentially along the pressure ring 311. One end of each pressure rod 312 is connected to the side of the pressure ring 311 facing away from the suction port 11, and the other end extends axially away from the suction port 11. The end of the pressure rod 312 connected to the pressure ring 311 abuts against the end of the mounting sleeve 24 to achieve axial positioning of the pressure sleeve 31 on the mounting sleeve 24.

[0106] When the pressure ring 311 is fitted onto the outer periphery of the mounting sleeve 24, the pressure rod 312 extends axially into the interior of the filter cup 33, pressing the filter bag 32, which is fitted onto the outer periphery of the pressure sleeve 31, against the inner circumferential wall of the filter cup 33, so that the filter bag 32 is flat and fits snugly against the inner surface of the filter cup 33. Multiple pressure rods 312 are evenly distributed circumferentially along the pressure ring 311, applying uniform pressure to the filter bag 32 to ensure complete fit between the filter bag 32 and the inner wall of the filter cup 33, preventing wrinkles or accumulation of the filter bag 32 due to localized lack of compression.

[0107] In this optional embodiment, the pressure ring 311 is fitted around the outer periphery of the mounting sleeve 24 to achieve radial positioning of the entire pressure sleeve 31, and the pressure rod 312 is connected to the end of the pressure ring 311 and abuts against the end of the mounting sleeve 24 to achieve axial positioning of the entire pressure sleeve 31. The two work together to ensure that the pressure sleeve 31 is accurately and reliably positioned on the mounting sleeve 24. Multiple pressure rods 312 are distributed circumferentially along the pressure ring 311 to apply uniform clamping force to the filter bag 32, ensuring that the filter bag 32 is flat and fits against the inner wall of the filter cup 33. This prevents the filter bag 32 from shifting, wrinkling, or locally accumulating due to airflow impact during use, thus ensuring the effective filtration area and filtration efficiency of the filter bag 32. At the same time, the pressure rods 312 extend axially away from the inlet 11, allowing the pressure rods 312 to penetrate deep into the filter cup 33 and press the filter bag 32 to the bottom of the filter cup 33, ensuring a complete fit of the filter bag 32 within the filter cup 33, further improving the filtration effect and the service life of the filter bag 32.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
