Description

Technical Field

[0001] This utility model relates to an automatic dust removal air filtration device, which is applicable to the field of air filtration technology. Background Technology

[0002] An air filtration system is a device that purifies the air. It uses filter materials to collect dust, particles, and other pollutants from the air and delivers clean air into the room, ensuring indoor air cleanliness. Over time, the filter elements in an air filtration system accumulate a large amount of dust, which not only easily breeds bacteria, affecting air purification efficiency, but also causes blockages inside the air filtration system, affecting its normal operation. Therefore, regular cleaning of the filter elements is necessary. Current cleaning methods for air filtration systems typically involve disassembling the filter elements for cleaning. While this ensures cleaning effectiveness, the disassembly and reassembly process is cumbersome, especially for larger air filtration systems. Their internal filter elements are often integrated filters composed of several individual filters, making disassembly and reassembly even more complex and consuming significant manpower and resources. In some cases, professional disassembly and reassembly are required, making the cleaning process very inconvenient. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model proposes an automatic dust removal air filtration device.

[0004] The present invention employs an automatic dust removal air filtration device, comprising a housing, a filter element assembly disposed within the housing, a dust collection box disposed below the filter element assembly, and a dust removal mechanism disposed above the filter element assembly. The dust removal mechanism includes a fixed frame fixedly connected to the inner wall of the housing, a movable frame movably connected to the lower part of the fixed frame and fixedly connected to the filter element assembly, a drive assembly for driving the movable frame to move downward, and a rebound assembly for applying force to the movable frame to move it upward. The drive assembly includes a sliding sleeve disposed on the fixed frame, a sliding column whose lower end is fixed to the movable frame and whose upper end is slidably inserted into the sliding sleeve, a drive motor fixedly disposed on the fixed frame, and a drive arm whose one end is fixedly connected to the output shaft of the drive motor. The other end of the drive arm is detachably abutted against the upper end of the sliding column and applies a downward force to the sliding column when abutting. After the filter element assembly has accumulated a large amount of dust during prolonged use, the drive motor is activated, which drives the drive arm to rotate. The other end of the drive arm abuts against the upper end of the sliding column during rotation, applying a downward force to the column. This drives the moving frame to move the filter element assembly downwards. As the column moves downwards, the other end of the drive arm gradually disengages from it. When the force applied by the drive arm to the column disappears, the moving frame instantly moves upwards and returns to its initial position under the action of the rebound component, causing the filter element assembly to vibrate once. This shakes off the dust adsorbed on the filter element assembly into the dust collection box below. Through the repeated action of the drive and rebound components, the filter element assembly vibrates repeatedly and rapidly, shaking off the dust adsorbed on it. This eliminates the need for manual disassembly of the filter element assembly, saving significant manpower and resources, greatly simplifying the cleaning process, and providing great convenience for dust removal and cleaning of the filter element assembly.

[0005] Furthermore, the rebound assembly includes at least one sliding hole in the fixed frame, a guide rod with its middle section passing through the sliding hole and its lower end fixed to the movable frame, and an elastic element sleeved on the upper part of the guide rod. A fixing element is provided at the upper end of the guide rod, and the two ends of the elastic element abut against the fixing element and the fixed frame, respectively. When the drive assembly drives the movable frame to move downward, the guide rod moves downward accordingly. The fixing element at the upper end of the guide rod compresses the elastic element. After the force applied by the drive assembly to the movable frame disappears, the movable frame will move upward under the force generated by the release of the elastic element, thus realizing the drive of the rebound assembly to the movable frame. Moreover, through the elastic element as a force-applying structure, the movable frame will also repeatedly vibrate under inertia after rebounding into place, further improving the dust shaking effect.

[0006] Furthermore, the upper part of the guide rod is threaded, and the fixing element is a nut that is threadedly connected to the guide rod. By setting the fixing element as a nut, the degree of compression of the elastic element in its initial state can be adjusted, thereby adjusting the force generated when it is released.

[0007] Furthermore, the projection of the drive arm onto a plane perpendicular to its rotation axis is teardrop-shaped, and the center of the arc at one end of the drive arm coincides with the rotation axis of the drive motor output shaft. The drive arm can detachably abut against the upper end of the slide column through the tip of its other end. The tip of the teardrop-shaped drive arm at the other end improves the smoothness of the entire process from contacting the slide column, pressing the slide column, to disengaging from the slide column, and avoids jamming.

[0008] Furthermore, a clearance groove is provided on the side of the sliding sleeve facing the drive arm to allow the drive arm to pass through. The clearance groove prevents interference between the sliding sleeve and the drive arm, and thus increases the height of the sliding sleeve, improving the stability of the sliding column within the sliding sleeve.

[0009] Furthermore, the filter element assembly divides the inner cavity of the housing into a filtration zone located above the filter element assembly and a dust collection zone located below the filter element assembly. The dust removal mechanism is located in the filtration zone, which contains the filtered environment, thus preventing excessive dust from causing malfunctions in the components of the dust removal mechanism. The dust collection box is located at the bottom of the dust collection zone, making it convenient to collect the filtered dust particles.

[0010] Furthermore, the filtration device also includes a fan installed within the filtration zone, an air outlet grille on the inner wall of the filtration zone, and a dust suction port on the inner wall of the dust collection zone, located between the dust collection box and the filter element assembly. Powered by the fan, air is drawn into the filtration device through the dust suction port, filtered by the filter element assembly, and then discharged through the air outlet grille, thus enabling the normal operation of the filtration device.

[0011] Furthermore, a door is provided on the side of the housing corresponding to the filter element assembly, and the size of the door is larger than the projection size of the filter element assembly on the door. This door allows for quick disassembly and installation of the filter element assembly, facilitating rapid maintenance and replacement in case of equipment failure or when the filter element assembly reaches the end of its service life.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] The automatic dust removal air filtration device of this utility model has a simple structure. The moving frame is driven by the drive component and the rebound component, which in turn drives the filter element assembly to shake up and down, shaking off the dust adsorbed on it. There is no need for personnel to manually disassemble the filter element assembly, saving a lot of manpower and material resources, greatly simplifying the operation process of cleaning the filter element assembly, and providing great convenience for dust removal and cleaning of the filter element assembly.

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Reference Appendix Figure 1-5The automatic dust removal air filtration device in this embodiment includes a housing 1, a filter element assembly 2 disposed within the housing 1, a dust collection box 3 disposed below the filter element assembly 2, and a dust removal mechanism 4 disposed above the filter element assembly 2. The dust removal mechanism 4 includes a fixed frame 41 fixedly connected to the inner wall of the housing 1, a movable frame 42 movably connected to the lower part of the fixed frame 41 and fixedly connected to the filter element assembly 2, a drive component 43 for driving the movable frame 42 to move downward, and a drive component 43 for applying force to the movable frame 42. The spring assembly 44 is moved upward by force. The drive assembly 43 includes a sliding sleeve 431 mounted on a fixed frame 41, a sliding column 432 whose lower end is fixed to a movable frame 42 and whose upper end is slidably inserted into the sliding sleeve 431, a drive motor 433 fixedly mounted on the fixed frame 41, and a drive arm 434 whose one end is fixedly connected to the output shaft of the drive motor 433. The other end of the drive arm 434 is detachably abutted against the upper end of the sliding column 432 and applies a downward force to the sliding column 432 when abutting. After the filter element assembly 2 has accumulated a large amount of dust during prolonged use, the drive motor 433 is activated, causing the drive arm 434 to rotate. During rotation, the other end of the drive arm 434 abuts against the upper end of the sliding column 432, applying a downward force to the sliding column 432. This drives the moving frame 42 to move the filter element assembly 2 downwards. As the sliding column 432 moves downwards, the other end of the drive arm 434 gradually disengages from the sliding column 432 during rotation. Once the force applied by the drive arm 434 to the sliding column 432 disappears, the moving frame 42 moves downwards. The frame 42 will move upward instantly and return to its initial position under the action of the rebound component 44, causing the filter element assembly 2 to vibrate up and down once, so as to shake off the dust adsorbed on the filter element assembly 2 into the dust collection box 3 below. Then, through the repeated action of the drive component 43 and the rebound component 44, the filter element assembly 2 will vibrate repeatedly and rapidly, shaking off the dust adsorbed on the filter element assembly 2. There is no need for personnel to manually disassemble the filter element assembly 2, saving a lot of manpower and resources, greatly simplifying the operation process of cleaning the filter element assembly, and providing great convenience for dust removal and cleaning of the filter element assembly.

[0025] In a more preferred embodiment, the rebound assembly 44 includes at least one sliding hole 441 formed on the fixed frame 41, a guide rod 442 with its middle portion passing through the sliding hole 441 and its lower end fixed to the movable frame 42, and an elastic element 443 sleeved on the upper part of the guide rod 442. A fixed element 444 is provided at the upper end of the guide rod 442, and the two ends of the elastic element 443 abut against the fixed element 444 and the fixed frame 41, respectively. When the drive assembly 43 drives the movable frame 42 to move downward, the guide rod 442 moves downward accordingly. The fixed element 444 at the upper end of the guide rod 442 compresses the elastic element 443. After the force applied by the drive assembly 43 to the movable frame 42 disappears, the movable frame 42 will move upward under the force generated by the release of the elastic element 443, thereby realizing the drive of the rebound assembly 44 on the movable frame 42. Furthermore, through the elastic element 443 as a force-applying structure, the movable frame 42 will also repeatedly vibrate under inertia after rebounding into place, further improving the dust-shaking effect.

[0026] In a more preferred embodiment, the upper part of the guide rod 442 is provided with threads, and the fixing member 444 is configured as a nut that is threadedly connected to the guide rod 442. By configuring the fixing member 444 as a nut, the degree of compression of the elastic member 443 in its initial state can be adjusted, thereby adjusting the force generated when it is released.

[0027] In a more preferred embodiment, the projection of the drive arm 434 onto a plane perpendicular to its rotation axis is teardrop-shaped, and the center of the arc at one end of the drive arm 434 coincides with the rotation axis of the output shaft of the drive motor 433. The drive arm 434 can detachably abut against the upper end of the slide column 432 through the tip of its other end. The tip of the other end of the teardrop-shaped drive arm 434 improves the smoothness of the entire process from contacting the slide column 432, pressing the slide column 432 to disengaging from the slide column 432, and avoids jamming.

[0028] In a more preferred embodiment, the sliding sleeve 431 has a clearance groove 435 on the side facing the drive arm 434 for the drive arm 434 to pass through. The clearance groove 435 avoids interference between the sliding sleeve 431 and the drive arm 434, and thus can increase the height of the sliding sleeve 431 and improve the stability of the sliding column 432 sliding in the sliding sleeve 431.

[0029] In a more preferred embodiment, the filter element assembly 2 divides the inner cavity of the housing 1 into a filtration zone 11 located above the filter element assembly 2 and a dust collection zone 12 located below the filter element assembly 2. The dust removal mechanism 4 is located in the filtration zone 11, which is the filtered environment, thus avoiding excessive dust that could cause the components in the dust removal mechanism 4 to malfunction. The dust collection box 3 is located at the bottom of the dust collection zone 12, which facilitates the collection of filtered dust particles.

[0030] In a more preferred embodiment, the filtration device further includes a fan 13 disposed within the filtration zone 11, an air outlet grille 14 formed on the inner wall of the filtration zone 11, and a dust suction port 15 formed on the inner wall of the dust collection zone 12, the dust suction port 15 being located between the dust collection box 3 and the filter element assembly 2. Powered by the fan 13, air is drawn into the filtration device through the dust suction port 15, filtered by the filter element assembly 2, and discharged through the air outlet grille 14, thus enabling the normal operation of the filtration device.

[0031] In a more preferred embodiment, a door 16 is provided on the side of the housing 1 at a position corresponding to the filter element assembly 2. The size of the door 16 is larger than the size of the projection of the filter element assembly 2 onto the door 16. By providing the door 16, the filter element assembly 2 can be quickly disassembled and installed, facilitating rapid maintenance and replacement in case of equipment failure or when the filter element assembly reaches the end of its service life.
