After the motor is started, it drives the reciprocating screw rod to rotate. Since the T-shaped connecting rod and the reciprocating screw rod are threadedly connected, the rotation of the reciprocating screw rod drives the T-shaped connecting rod to slide back and forth left and right. When the T-shaped connecting rod slides to the right, it drives the single-sided scraper to slide to the right.

The end of the piston rod 2 away from the J-shaped cylinder is rotatably connected to the rotating pressure plate. When the one-way partition door rotates upward, it drives the piston rod 1 to slide upward through contact. When the piston rod 1 slides upward, it squeezes the air inside the J-shaped cylinder. After the air inside the J-shaped cylinder is squeezed, it drives the piston rod 2 to slide downward. When the piston rod 2 slides downward, it drives the rotating pressure plate to rotate downward.

[0009] According to the above technical solution, the dust prevention device also includes a valve control rod, an L-shaped push rod, a sprayer and a rotating bottom door.

The valve control rod is rotatably installed on the left side of the hydraulic valve, the L-shaped push rod is fixedly installed on the top of the rotating pressure plate, the sprayer is fixedly installed on the top of the inner wall of the processing box, and the sprayer and the hydraulic valve are connected through a hose. The rotating bottom door is rotatably installed on the right side of the inner wall of the processing box, and the rotating pressure plate drives the L-shaped push rod to rotate together during the upward rotation. When the L-shaped push rod rotates, it drives the valve control rod to deflect through contact and opens the hydraulic valve, so that the clean water in the clean water box passes through the hydraulic valve and is sprayed out from the sprayer in the form of mist.

[0010] The cam is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is provided with a plurality of springs, and the plurality of springs are provided with a plurality of springs.

[0011] According to the above technical solution, a dust exhaust device is provided inside the processing box, and the dust exhaust device includes a pulley, a transmission rope, a positioning rod, a C-shaped scraper and a nylon rope. The pulley is rotatably installed at the bottom of the processing box, the positioning rod is fixedly installed on the right side of the processing box, the positioning rod is fixedly connected to the bottom of the rotating bottom door by a transmission rope, and the end of the transmission rope away from the rotating bottom door is fixedly connected to a pull ring, the C-shaped scraper is slidably installed on the inner wall of the processing box, and the C-shaped scraper is fixedly connected to the rotating bottom door by a nylon rope. The sliding of the pull ring drives the transmission rope to slide, and the sliding of the transmission rope drives the rotating bottom door to rotate downward and opens the bottom of the processing box, and the impurities collected inside are discharged therefrom under the action of gravity.

[0012] According to the above technical solution, the dust exhaust device also includes a cam and a bevel latch. The cam is fixedly mounted on the front of the rotating pressure plate through a connecting shaft, and the bevel latch is slidably mounted on the front of the processing box. The bevel latch slides through the front of the processing box. The rotation of the cam drives the bevel latch to slide through contact. After the bevel latch slides, its top contacts the rotating bottom door and forms a limit, so that the rotating bottom door cannot rotate downward.

[0013] According to the above technical solution, the transmission rope is wrapped around the pulley, and the sliding friction is converted into rolling friction through the pulley to extend the service life of the transmission rope. The inclined latch is located on the movement trajectory of the cam, so that the rotation of the cam can drive the inclined latch to slide. A second reset spring is provided between the inclined latch and the processing box, so that after the cam rotates upward and disengages from the inclined latch, the inclined latch can return to its initial position in time to release the limit.

[0014] The present invention provides an environmentally friendly composite filter structure for an air purifier. It has the following beneficial effects: (1) This invention drives the reciprocating screw to rotate by an electric motor, thereby driving the single-sided scraper to slide back and forth. During the sliding process, the dust and other impurities attached to the surface of the air filter plate are scraped off by contact. The service life of the air filter plate is extended by regular cleaning. At the same time, the scraped impurities are collected in the collection box. When the T-shaped connecting rod moves to the rightmost side, the sliding bottom door is driven to slide by the contact angle top block, thereby transferring the impurities in the collection box to the processing box, avoiding the impurities remaining in the box body and causing dust to be generated inside during operation.

[0015] (2) This invention pushes the one-way partition door to rotate through the collection box, and the one-way partition door drives the rotating pressure plate to rotate downward through the air pressure system, so that when the collection box transfers the impurities to the processing box, the rotating pressure plate rotates downward and squeezes the impurities, thereby compacting the powder or granular impurities, avoiding excessive impurities collected inside the processing box to cause dust. At the same time, when the rotating pressure plate is reset, it drives the L-shaped push rod to deflect the valve control rod through contact to open the hydraulic valve, so that the clean water in the clean water box is sprayed into the inside of the processing box through the sprayer, further improving the anti-dust effect while avoiding impurities adhering to the inner wall of the processing box.

[0016] (3) In this invention, the operator pulls the pull ring, which drives the rotating bottom door to rotate through the transmission rope, so that the impurities collected inside the processing box are discharged from it. At the same time, the rotation of the rotating bottom door drives the C-shaped scraper to slide through the nylon rope, so that the inner wall of the processing box is scraped and cleaned, and impurities are prevented from adhering to the inner wall due to long-term operation. At the same time, when the rotating pressure plate rotates, it drives the inclined pin to slide through the cam, so that a limit is formed between it and the rotating bottom door, so that the rotating bottom door cannot be rotated downward. When the device is in the process of compacting impurities, the rotating bottom door cannot be driven by pulling the pull ring, and dust is avoided due to operator error.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 3One embodiment of the present invention is: an environmentally friendly composite filter structure for an air purifier, comprising a box body 1, an activated carbon plate 2 slidingly penetrates the front of the box body 1, an air outlet 3 is provided on the top of the box body 1, an air filter plate 4 is fixedly installed on the inner wall of the box body 1, a motor 5 is fixedly installed on the left side of the box body 1, an air intake fan 6 is provided on the rear inner wall of the box body 1, an output end of the motor 5 is fixedly connected to a reciprocating screw rod 701, a T-shaped connecting rod 702 is slidably installed on the circumferential surface of the reciprocating screw rod 701, the T-shaped connecting rod 702 is threadedly connected to the reciprocating screw rod 701, a single-sided scraper 703 is fixedly installed on the top of the T-shaped connecting rod 702, a collection box 704 is fixedly installed on the right side of the T-shaped connecting rod 702, and the collection box 704 A sliding bottom door 705 is installed on the bottom slidingly, and an angular top block is fixedly installed on the bottom of the sliding bottom door 705. A processing box 706 is fixedly installed on the right side of the box body 1. A dust exhaust port is opened on the right side of the inner wall of the box body 1, and a one-way partition door 707 is rotatably installed on the right side of the inner wall of the box body 1. The reciprocating screw rod 701 is driven to rotate by the motor 5, thereby driving the single-sided scraper 703 to slide back and forth. During the sliding process, the dust and other impurities attached to the surface of the air filter plate 4 are scraped off through contact. When the T-shaped connecting rod 702 moves to the far right, the sliding bottom door 705 is driven to slide by the contact angular top block, thereby realizing the transfer of impurities in the collection box 704 to the processing box 706, avoiding the impurities remaining in the box body 1.

[0021] The reciprocating screw 701 rotates through the box body 1, and the top of the single-sided scraper 703 contacts the air filter plate 4, so that the single-sided scraper 703 can scrape and clean the surface of the air filter plate 4 through contact, and the one-way partition door 707 is located on the movement trajectory of the collection box 704, so that the sliding of the collection box 704 can drive the one-way partition door 707 to rotate, and the dust exhaust port is located on the movement trajectory of the angular top block, so that when the collection box 704 moves to the far right, the angular top block can drive the sliding bottom door 705 to slide, and a reset spring 1 is provided between the sliding bottom door 705 and the collection box 704, so that when the collection box 704 slides to the left, the sliding bottom door 705 can automatically return to its initial state.

[0022] During operation: When the device enters the operating state, the air intake fan 6 and the motor 5 are started. The air intake fan 6 draws air from the bottom into the box body 1. The air passes through the air filter plate 4 and the activated carbon plate 2 and is then discharged from the box body 1 through the air outlet 3. After the motor 5 is started, it drives the reciprocating screw 701 to rotate. Since the T-shaped connecting rod 702 is threadedly connected to the reciprocating screw 701, the rotation of the reciprocating screw 701 drives the T-shaped connecting rod 702 to slide back and forth. When the T-shaped connecting rod 702 slides to the right, it drives the single-sided scraper 703 to slide to the right. During the rightward sliding process of the single-sided scraper 703, it scrapes and cleans impurities attached to the bottom of the air filter plate 4 through contact, preventing the impurities attached to the bottom of the air filter plate 4 from affecting the overall air purification quality of the device. At the same time, the scraped impurities fall into the collection box 704 under the action of gravity. When the T-shaped connecting rod 702 continues to slide to the right, the collection box 704 drives the one-way partition door 707 to rotate upward and open the dust discharge port through contact. At the same time, the dust discharge port drives the angular top block to slide to the left relative to the collection box 704 through contact. The sliding of the angular top block drives the sliding bottom door 705 to slide, thereby realizing that the impurities collected in the collection box 704 are transferred to the processing box 706 under the action of gravity, avoiding the impurities remaining in the box body 1 after scraping, causing the air flow during operation to cause internal dust and thus affect the overall air purification effect of the device. When the T-shaped connecting rod 702 rotates to the left to return to the initial position, the processing box 706 is disengaged from the one-way partition door 707. After disengagement, the one-way partition door 707 returns to its initial vertical position under the action of gravity, separating the box body 1 and the processing box 706, avoiding backflow during operation causing impurities in the processing box 706 to flow back into the box body 1.

[0023] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, a dust prevention device is provided inside the processing box 706, and the dust prevention device includes a J-shaped cylinder 801, a piston rod 1 802, a piston rod 2 803 and a rotating pressure plate 804. The J-shaped cylinder 801 is fixedly mounted on the top of the inner wall of the processing box 706, the piston rod 1 802 is slidably mounted on the left inner wall of the J-shaped cylinder 801, the piston rod 2 803 is slidably mounted on the right inner wall of the J-shaped cylinder 801, and the rotating pressure plate 804 is rotatably mounted on the inner wall of the processing box. On the right side of the inner wall of 706, the end of the piston rod 2 803 away from the J-shaped cylinder 801 is rotatably connected to the rotating pressure plate 804, and the one-way partition door 707 is pushed to rotate through the collection box 704. The one-way partition door 707 drives the rotating pressure plate 804 to rotate downward through the pneumatic component, so that when the collection box 704 transfers the impurities to the processing box 706, the rotating pressure plate 804 rotates downward and squeezes the impurities, thereby compacting the powder or granular impurities, avoiding excessive impurities collected inside the processing box 706 and causing dust.

[0024] The anti-dust device also includes a valve control rod 805, an L-shaped push rod 806, a sprayer 807 and a rotating bottom door 808. A hydraulic valve is fixedly installed on the right side of the processing box 706, and a clean water box is provided inside the box body 1. The clean water box and the hydraulic valve are connected through a hose. The valve control rod 805 is rotatably installed on the left side of the hydraulic valve, the L-shaped push rod 806 is fixedly installed on the top of the rotating pressure plate 804, and the sprayer 807 is fixedly installed on the top of the inner wall of the processing box 706. The sprayer 807 and the hydraulic valve are connected through a hose. The rotating bottom door 808 is rotatably installed on the right side of the inner wall of the processing box 706. When the rotating pressure plate 804 is reset, the L-shaped push rod 806 is driven to deflect the valve control rod 805 through contact to open the hydraulic valve, so that the clean water in the clean water box is sprayed into the interior of the processing box 706 through the sprayer 807, further improving the anti-dust effect while preventing impurities from adhering to the inner wall of the processing box 706.

[0025] The piston rod 802 is located on the motion track of the one-way partition door 707, so that the rotation of the one-way partition door 707 can drive the piston rod 802 to slide upward. A dustproof cloth is provided between the rotating pressure plate 804 and the inner wall of the processing box 706. The dustproof cloth is used to prevent impurities from falling onto the top of the rotating pressure plate 804 during the impurity transfer process and failing to be pressed tightly. The valve control rod 805 is located on the motion track of the L-shaped top rod 806, so that when the L-shaped top rod 806 rotates, the valve control rod 805 is deflected by contact and the hydraulic valve is opened. The valve control rod 805 and the inner wall of the processing box 706 are provided with a dustproof cloth. The dustproof cloth is used to prevent impurities from falling onto the top of the rotating pressure plate 804 during the impurity transfer process and failing to be pressed tightly. A vortex spring 1 is arranged between the hydraulic valves, so that after the L-shaped push rod 806 is out of contact with the valve control rod 805, the valve control rod 805 can automatically return to its original position to close the hydraulic valve. A vortex spring 2 is arranged between the rotating bottom door 808 and the processing box 706, so that the rotating bottom door 808 can maintain a horizontal state under normal conditions. A vortex spring 3 is arranged between the rotating pressure plate 804 and the processing box 706, so that after the collection box 704 is out of contact with the one-way partition door 707, the rotating pressure plate 804 can automatically return to its original position.

[0026] The dust removal device is provided inside the processing box 706, and the dust removal device includes a pulley 903, a transmission rope 904, a positioning rod 905, a C-shaped scraper 906 and a nylon rope 907. The pulley 903 is rotatably mounted on the bottom of the processing box 706, and the positioning rod 905 is fixedly mounted on the right side of the processing box 706. The positioning rod 905 is fixedly connected to the bottom of the rotating bottom door 808 by a transmission rope 904. The transmission rope 904 is fixedly connected to a pull ring at one end away from the rotating bottom door 808. The C-shaped scraper 906 is slidably mounted on the inner wall of the processing box 706, and the C-shaped scraper 906 is fixedly connected to the rotating bottom door 808 by a nylon rope 907. When the operator pulls the pull ring, the pull ring drives the rotating bottom door 808 to rotate through the transmission rope 904, so that the impurities collected in the processing box 706 are discharged therefrom. At the same time, the rotation of the rotating bottom door 808 drives the C-shaped scraper 906 to slide through the nylon rope 907, thereby scraping and cleaning the inner wall of the processing box 706.

[0027] The dust removal device also includes a cam 901 and a bevel latch 902. The cam 901 is fixedly mounted on the front of the rotating pressure plate 804 through a connecting shaft, and the bevel latch 902 is slidably mounted on the front of the processing box 706. The bevel latch 902 slides through the front of the processing box 706. When the rotating pressure plate 804 rotates, it drives the bevel latch 902 to slide through the cam 901, so that a limit is formed between it and the rotating bottom door 808, so that the rotating bottom door 808 cannot be rotated downward, thereby achieving the goal that when the device is in the process of compacting impurities, the rotating bottom door 808 cannot be driven by pulling the pull ring.

[0028] The transmission rope 904 wraps around the pulley 903, and the sliding friction is converted into rolling friction through the pulley 903 to extend the service life of the transmission rope 904. The inclined latch 902 is located on the movement trajectory of the cam 901, so that the rotation of the cam 901 can drive the inclined latch 902 to slide. A second return spring is provided between the inclined latch 902 and the processing box 706, so that after the cam 901 rotates upward and disengages from the inclined latch 902, the inclined latch 902 can return to its initial position in time to release the limit. The rotating bottom door 808 is located on the movement trajectory of the inclined latch 902, so that after the inclined latch 902 slides, it contacts the rotating bottom door 808 and forms a limit so that the rotating bottom door 808 cannot continue to slide downward.

[0029] When the embodiment is working, when the one-way partition door 707 rotates upward, it drives the piston rod 1 802 to slide upward through contact. When the piston rod 1 802 slides upward, it squeezes the air inside the J-shaped cylinder 801. After the air inside the J-shaped cylinder 801 is squeezed, it drives the piston rod 2 803 to slide downward. When the piston rod 2 803 slides downward, it drives the rotating pressure plate 804 to rotate downward, so that when the dust inside the collection box 704 is transferred to the processing box 706, the rotating pressure plate 804 rotates downward to compact the powder or granular impurities, thereby avoiding the dust from being raised inside the processing box 706 when the one-way partition door 707 is not closed during the transfer process, thereby causing the dust to be sucked back into the box body 1. As the T-shaped connecting rod 702 slides to the left, that is, during the reset process of the one-way partition door 707, the one-way partition door 707 disengages from the piston rod 1 802. After disengagement, the rotating pressure plate 804 rotates in the opposite direction, that is, upward, under the rebound force of the spiral spring three. During the upward rotation of the rotating pressure plate 804, the L-shaped push rod 806 is driven to rotate together. When the L-shaped push rod 806 rotates, it drives the valve control rod 805 to deflect and open the hydraulic valve through contact, so that the clean water in the clean water box passes through the hydraulic valve and is sprayed out from the sprayer 807 in the form of mist, further promoting the anti-dust effect while keeping the inner wall of the processing box 706 moist, thereby avoiding impurities adhering to the inner wall of the processing box 706.

[0030] When excessive impurities accumulate inside the processing box 706 after the device has been in operation for a long time, it is necessary to discharge the impurities in a timely manner. During discharge, the operator pulls the pull ring to slide, and the sliding of the pull ring drives the transmission rope 904 to slide. The sliding of the transmission rope 904 drives the rotating bottom door 808 to rotate downward, opening the bottom of the processing box 706, and the impurities collected inside are discharged from it under the action of gravity. As the rotating bottom door 808 rotates downward, the nylon rope 907 drives the C-shaped scraper 906 to slide downward, thereby scraping off impurities attached to the inner wall of the processing box 706 during the dust removal process, thereby preventing impurities from adhering to the inner wall of the processing box 706 after the device has been in operation for a long time. At the same time, when the rotating pressure plate 804 rotates downward, it drives the cam 901 to rotate together through the connecting shaft. The rotation of the cam 901 drives the inclined latch 902 to slide through contact. After the inclined latch 902 slides, its top contacts the rotating bottom door 808 and forms a limit, making it impossible for the rotating bottom door 808 to rotate downward. As a result, when the anti-dust device is performing the impurity compacting step, the operator cannot pull the pull ring to drive the rotating bottom door 808 to rotate downward, avoiding the operator's mistaken operation due to negligence and pulling the rotating bottom door 808 when compacting impurities, thereby improving the stability of the device during operation.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
