During the process, the reciprocating sliding of the resistance rod resists the protrusion, so that the filter plate rotates. When the resistance rod releases the resistance to the protrusion, the torsion spring resets the filter plate, so that the filter plate can shake the paint.

[0017] 2. When the device of the present application is in use, when the filter plate is driven to rotate by the resistance rod, the scraper will also be driven to rotate, so that the scraper will not affect the rotation of the filter plate. When the filter plate is reset, the scraper is pushed to reset by the reset of the arc-shaped spring sheet, so that when the device is in use, the scraper and the filter plate will not interfere with each other's work, thereby increasing the feasibility of the device.

[0018] 3. In the normal state of the present application, the return spring forces the sliding frame to move in the direction away from the channel, with the middle point of the length of the reciprocating screw rod as the reference point, the end of the reciprocating screw rod facing the accommodating chamber is set as the resistance end, and the end away from the accommodating chamber is set as the pulling end, the resistance end is close to the channel and the pulling end is away from the channel, when the driving block moves toward the resistance end, it drives the resistance rod to move into the accommodating chamber, so that it resists the protrusion, causing the filter plate to rotate and tilt, when the resistance rod is reset, it will not immediately release the resistance from the protrusion, so that the filter plate remains tilted, providing enough time for the movement of the paint, when the driving block moves to the pulling end, the driving block pulls the connecting rope to move in the direction away from the channel, so that the connecting rope pulls the sliding block to slide in the accommodating chamber The cam is then retracted to allow the slider to move in a direction that is close to the channel and to compress the return spring. When the drive block moves to the contact end again, the connecting rope is relaxed, and the return spring pushes the slider to return to its original position, so that the slider can drive the entire scraper plate to slide in the accommodating chamber, and is driven by the reciprocating screw rod so that when the contact rod contacts the filter plate and rotates, the scraper plate will not slide in the accommodating chamber. When the scraper plate slides in the accommodating chamber, the contact rod will not cause the filter plate to rotate. The two are driven alternately so that when the scraper plate scrapes the paint, the filter plate is in a horizontal direction, and there is a larger contact area between the scraper plate and the filter plate, thereby increasing the scraping effect of the scraper plate on the paint and increasing the practicality of the device.

[0019] 4. When the device of the present application is in use, the reciprocating screw drives the driving block, which drives the piston rod to reciprocate through the driving block, thereby causing the piston rod to inflate the piston cylinder, so that the airflow enters the ventilation pipe through the connecting pipe and the connecting sleeve, and the airflow is blown from the air outlet pipe to the filter holes on the filter plate, thereby blowing the paint in the filter holes. Since polyester insulating paint is relatively thick and has poor fluidity, the polyester insulating paint can fall better in the filter holes by blowing air, thereby reducing the possibility of the polyester insulating paint stagnating in the filter holes and clogging the filter holes, thereby increasing the practicality of the device.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Embodiment 1

[0022] like Figure 1 - Fig.12 As shown, the present application provides a polyester insulating varnish preparation device and process in Example 1, comprising: The installation shell 1 has a receiving cavity 101 formed thereon, and an inlet 102 for communicating with the receiving cavity 101 is formed on the installation shell 1. When in use, the paint is discharged into the receiving cavity 101 through the inlet 102; The filter plate 2 is rotatably installed in the accommodating chamber 101. The filter plate 2 and the accommodating chamber 101 are rotatably connected via a rotating shaft. A torsion spring 201 is installed between the rotating shaft of the filter plate 2 and the inner wall of the accommodating chamber 101. The torsion spring 201 drives the filter plate 2 to rotate in the accommodating chamber 101 through its elastic deformation. A protrusion 202 is installed on one side of the filter plate 2. The protrusion 202 is installed on one side of the width direction of the filter plate 2. A plate body is installed on the opposite side of the protrusion 202 in the accommodating chamber 101. The plate body is located below the filter plate 2 and is used to carry the filter plate 2, so that when the filter plate 2 rotates to contact with the plate body, the rotation of the filter plate 2 in this direction is restricted. A resistance rod 203 is slidably installed on the mounting shell 1. The resistance rod 203 is used to resist the protrusion 202 so that the filter plate 2 can rotate in the accommodating chamber 101. When in use, The sliding of the resistance rod 203 causes it to resist the protrusion 202, forcing the filter plate 2 to rotate in the direction of being resisted, so that the filter plate 2 is tilted. At this time, the rod body of the resistance rod 203 still resists the protrusion 202, so that the filter plate 2 can maintain the tilted direction, so that the paint has enough time to move. When the resistance rod 203 is reset to release the resistance with the protrusion 202, the torsion spring 201 is reset to pull the filter plate 2 to reset. When the filter plate 2 is reset to contact with the plate body, the rotation of the filter plate 2 is restricted by the plate body, so that the filter plate 2 is restored to the horizontal direction. When in use, the activity of the paint on the filter plate 2 is increased by the rotation of the filter plate 2, so that the paint can be spread on the filter plate 2, reducing the accumulation of the paint, facilitating the filtration of the paint, and increasing the efficiency of the filtration of the paint. The scraper plate 3 is slidably mounted in the accommodating chamber 101. The scraper plate 3 is located above the upper surface of the filter plate 2. A driving member 4 connected to the scraper plate 3 is installed in the accommodating chamber 101. The driving member 4 drives the scraper plate 3 to reciprocate on the filter plate 2. The scraper plate 3 slides along the length direction of the accommodating chamber 101. When in use, the scraper plate 3 slides in the accommodating chamber 101 through the cooperation of the driving member 4. The scraper plate 3 slides alternately with the abutment rod 203. When the abutment rod 203 abuts against the protrusion 202 to reset, the filter plate 2 is in the horizontal direction. At this time, the scraper plate 3 slides to smooth the paint again, further increasing the filtration efficiency of the device for filtering the paint and increasing the practicality of the device. Compared with the prior art, when in use, the paint is discharged into the accommodating chamber 101 from the inlet 102. During the process, the protrusion 202 is resisted by the reciprocating sliding of the resistance rod 203, so that the filter plate 2 rotates. When the resistance rod 203 releases the resistance to the protrusion 202, the torsion spring 201 resets the filter plate 2, so that the filter plate 2 can shake the paint. During the process, the scraper plate 3 scrapes the paint through the cooperation of the driving member 4, further increasing the mobility of the paint on the filter plate 2, so that the paint can be spread on the filter plate 2, which is convenient for filtering the paint, thereby increasing the filtering efficiency of the paint. Embodiment 2

[0023] like Figure 3 and Figure 8 As shown, the second embodiment further discloses the mounting shell 1, the filter plate 2, the scraper plate 3 and the driving member 4 on the basis of the first embodiment. In the second embodiment, the scraper plate 3 includes a sliding block 305 slidably mounted in the accommodating cavity 101. The sliding block 305 is slidably mounted in the accommodating cavity 101 along the length direction of the accommodating cavity 101. L-shaped plates are symmetrically mounted in the accommodating cavity 101. The sliding block 305 is slidably mounted in the middle of the two L-shaped plates. The sliding block 305 can only slide in the accommodating cavity 101 along a straight line direction by the shielding of the inner wall of the L-shaped plate. The sliding block 305 is slidably mounted with the sliding frame 301 through the connecting spring 306, the sliding block 305 is mounted with a cylinder, the sliding frame 301 is mounted with a rod, the end of the rod is slidably inserted in the cylinder, the connecting spring 306 is located in the cylinder and connected to the rod, Figure 1 From the main viewing angle, the sliding block 305 is slidably connected with the sliding frame 301 in the vertical direction; A plurality of accommodating shells 302 are arranged in a linear array along the length direction of the accommodating cavity 101 on the sliding frame 301. A scraper 303 is hinged inside the accommodating shell 302. A vertical line is drawn with the center of the end of the rotating shaft of the filter plate 2 as a positioning line. The center of the hinge point between the scraper 303 and the accommodating shell 302 is also on the positioning line, so that when the filter plate 2 is tilted, its tilted side will resist the scraper 303, so that the scraper 303 can also rotate with it, so that the scraper 303 will not affect the rotation of the filter plate 2; An arc-shaped spring piece 304 is installed in the accommodating shell 302. The arc-shaped spring piece 304 contacts the scraper 303. When the scraper 303 rotates with the filter plate 2, the arc-shaped spring piece 304 is pressed against. When the filter plate 2 is reset, the scraper 303 is reset due to the resistance of the arc-shaped spring piece 304. When the filter plate 2 is restored to the horizontal direction, the scraper 303 is also pushed to reset, or the scraper 303 is pushed to rotate to a position where the scraper 303 can contact the paint through a larger area, so that the scraper 303 can push the paint normally. When the device is in use, when the filter plate 2 is driven to rotate by the resistance rod 203, the scraper 303 will also be driven to rotate, so that the scraper 303 will not affect the rotation of the filter plate 2. When the filter plate 2 is reset, the scraper 303 is pushed to reset by the reset of the arc-shaped spring piece 304, so that when the device is in use, the scraper 303 and the filter plate 2 will not interfere with each other's work, thereby increasing the feasibility of the device.

[0024] like Figure 3 , Figure 5 and Fig.11 As shown, in the second embodiment, the mounting shell 1 is provided with a mounting cavity 103 connected with the accommodating cavity 101, the driving member 4 includes a reciprocating screw rod 401 rotatably mounted in the mounting cavity 103, a driving motor 8 is installed in the mounting cavity 103, the output shaft of the driving motor 8 is coaxially connected with the reciprocating screw rod 401, the mounting cavity 103 has an opening toward the accommodating cavity 101, and the driving motor 8 is used to drive the reciprocating screw rod 401 to rotate in the mounting cavity 103; A driving block 5 is meshed on the reciprocating screw rod 401, and the driving block 5 is slidably matched with the installation cavity 103. The driving block 5 is connected to the resistance rod 203. A groove body is provided in the installation cavity 103, and one end of the driving block 5 is slidably matched with the groove body. The driving block 5 can only slide in the installation cavity 103 along a straight line due to the restriction of the inner wall of the groove body. As a result, when the reciprocating screw rod 401 rotates, the driving block 5 is driven to reciprocate on the reciprocating screw rod 401. The reciprocating motion of the driving block 5 drives the resistance rod 203 to reciprocate in the accommodating cavity 101. A plate body is installed at the end of the resistance rod 203, so that When the resistance rod 203 moves toward the installation cavity 103 and moves to the maximum direction, the opening of the installation cavity 103 is sealed, which reduces the possibility of paint entering the installation cavity 103 and increases the resistance area between the resistance rod 203 and the protrusion 202, so that when the resistance rod 203 slides into the accommodating cavity 101, it can smoothly resist the protrusion 202, ensuring the feasibility of the device. During the process, the resistance rod 203 is not only used to resist the protrusion 202, but also can play the role of a stopper to cover the opening of the installation cavity 103, increasing the practicality of the resistance rod 203; A connecting rope 6 is installed on the driving block 5, and a channel 7 for the connecting rope 6 to pass through is provided on the mounting shell 1. The channel 7 is communicated with the accommodating chamber 101. The free end of the connecting rope 6 passing through the channel 7 in the accommodating chamber 101 is connected to the sliding block 305. A return spring 307 is installed between the sliding block 305 and the inner wall of the accommodating chamber 101. The reciprocating screw rod 401 is connected to the sliding block 305 through the driving block 5 and the connecting rope 6, so that the driving member 4 is connected to the scraper plate 3. The inner wall of the channel 7 contacts the connecting rope 6, thereby guiding the connecting rope 6, which plays a guiding role. A plurality of blocks are installed in the mounting chamber 103, and an arc groove is provided on the block. The connecting rope 6 is accommodated through the arc groove, and the connecting rope 6 is fixed and limited, which increases the stability of the connecting rope 6 when in use. In normal state, the return spring 307 forces the sliding frame 301 to move in the direction away from the channel 7. With the middle point of the length of the reciprocating screw rod 401 as the reference point, the end of the reciprocating screw rod 401 facing the accommodating chamber 101 is set as the resistance end, and the end away from the accommodating chamber 101 is set as the pulling end. The resistance end is close to the channel 7 and the pulling end is away from the channel 7. When the driving block 5 moves toward the resistance end, it drives the resistance rod 203 to move into the accommodating chamber 101, so that it resists the protrusion 202, so that the filter plate 2 rotates and tilts. When the resistance rod 203 is reset, it will not immediately release the resistance from the protrusion 202, so that the filter plate 2 remains tilted, providing enough time for the movement of the paint. When the driving block 5 moves to the pulling end, the driving block 5 pulls the connecting rope 6 to move in the direction away from the channel 7, so that the connecting rope 6 pulls the sliding block 305 to slide in the accommodating chamber 101 The sliding block 305 is pushed back to return to its original position by the return spring 307, so that the sliding block 305 can drive the entire scraper plate 3 to slide in the accommodating chamber 101, and is driven by the reciprocating screw rod 401, so that when the resistance rod 203 resists the rotation of the filter plate 2, the scraper plate 3 will not slide in the accommodating chamber 101, and when the scraper plate 3 slides in the accommodating chamber 101, the resistance rod 203 will not cause the filter plate 2 to rotate, and the two are driven alternately, so that when the scraper plate 3 scrapes the paint, the filter plate 2 is in a horizontal direction, and there can be a larger contact area between the scraper plate 3 and the filter plate 2, thereby increasing the scraping effect of the scraper plate 3 on the paint, thereby increasing the practicability of the device.

[0025] like Figure 2 and Fig.12As shown, in the second embodiment, a sandwich 204 is provided on the filter plate 2, a vent pipe 206 is installed in the sandwich 204, an outlet pipe 205 penetrating the sandwich 204 is installed on the vent pipe 206, a one-way valve is installed in the outlet pipe 205, and the one-way valve allows the airflow to only be directed from the inside of the outlet pipe 205 to the outside of the outlet pipe 205. The sandwich 204 is not only used to install the vent pipe 206, but also to reduce the weight of the filter plate 2, so that the filter plate 2 can be better rotated, thereby increasing the practicality of the device; The opening of the air outlet pipe 205 is located in the filter hole on the filter plate 2, and the axis of the air outlet pipe 205 is perpendicular to the axis of the filter hole on the filter plate 2, so that the opening of the air outlet pipe 205 is perpendicular to the opening of the filter hole. When the paint falls from the filter hole, the possibility of the paint entering the air outlet pipe 205 when falling is reduced, the possibility of the air outlet pipe 205 being blocked is reduced, and the waste of paint is also reduced; A connecting sleeve 9 connected to the ventilation pipe 206 is installed on one side of the filter plate 2. The filter plate 2 is rotatably connected to the inner wall of the accommodating chamber 101 through the connecting sleeve 9. The connecting sleeve 9 not only plays a role of ventilation, but also plays a role of a rotating shaft, which increases the practicality of the connecting sleeve 9. A piston cylinder 10 is installed in the installation cavity 103, a connecting pipe 11 connected to the connecting sleeve 9 is installed on the piston cylinder 10, an air inlet pipe 12 is installed on the piston cylinder 10, a one-way valve is also installed in the air inlet pipe 12, a piston rod 13 is slidably installed in the piston cylinder 10, the piston rod 13 is connected to the driving block 5, and the one-way valve in the air inlet pipe 12 allows the external airflow to enter the piston cylinder 10 in one direction only; When the device is in use, the reciprocating screw 401 drives the driving block 5, and the driving block 5 drives the piston rod 13 to reciprocate, so that the piston rod 13 inflates the piston cylinder 10, so that the airflow enters the vent pipe 206 through the connecting pipe 11 and the connecting sleeve 9, and the airflow is blown from the air outlet pipe 205 to the filter holes on the filter plate 2, and the paint in the filter holes is blown. Since the polyester insulating paint is relatively thick and has poor fluidity, the polyester insulating paint can fall better in the filter holes by blowing, which also reduces the possibility of the polyester insulating paint stagnating in the filter holes and blocking the filter holes, thereby increasing the practicality of the device; When the airflow blows onto the inner wall of the filter hole, it is divided into upward and downward airflows. The downward airflow blows the paint to make it move downward, and the upward airflow contacts the paint located above. The upper surface of the filter plate 2 is the place where the paint is carried, so that the mass of this part of the paint is large, so that the upward airflow has little effect on the paint, and the downward airflow is used to assist in providing power for the paint to move downward. The paint falls mainly through its own gravity, so the upward airflow has little effect on the paint. When the paint falls in the filter hole, the first line of protection is provided by the opening of the air outlet pipe 205 which is perpendicular to the opening of the filter hole, and then air is blown to the outside through the air outlet pipe 205 to provide the second line of protection, and finally the third line of protection is provided by the one-way valve, thereby reducing the possibility of the paint entering the air outlet pipe 205 and increasing the feasibility of the device.

[0026] like Figure 2 and Figure 4 As shown, in the second embodiment, a hinged rod 14 is hinged on the driving block 5, and a driving gear 15, a transmission gear 16 and a connecting gear 17 that mesh with each other are rotatably installed in the installation cavity 103. The diameter of the driving gear 15 is larger than the diameter of the transmission gear 16, and the diameter of the transmission gear 16 is larger than the diameter of the connecting gear 17. The free end of the hinged rod 14 is hinged to the driving gear 15, and a connecting rod 18 is hinged on the connecting gear 17. The free end of the connecting rod 18 is hinged to the piston rod 13. The driving block 5, the hinged rod 14 and the driving gear 15 form a crank connecting rod structure, so that when the driving block 5 slides back and forth, the position of the free end of the hinged rod 14 in the horizontal direction is driven to change, and the driving gear 15 is pushed or pulled by the hinged rod 14 to rotate, and the connecting gear 17, the connecting rod 18 and the piston rod 13 also form a crank slider structure. When the linkage gear 17 rotates, the horizontal position of the linkage rod 18 is changed, and then the piston rod 13 is pushed or pulled by the linkage rod 18 to reciprocate in the piston cylinder 10 to inflate. The linkage gear 17 is connected to the driving gear 15 by the transmission gear 16, and the transmission is performed between the two by the transmission gear 16, so that when the driving gear 15 rotates, the linkage gear 17 can be driven to rotate by the transmission gear 16, ensuring that the driving gear 15 can be closer to the driving block 5, and also ensuring that the linkage gear 17 can be closer to the piston rod 13, so that the installation distribution of the driving gear 15 and the linkage gear 17 is more reasonable, so that the driving block 5 can better drive the driving gear 15 to rotate, and the linkage gear 17 can better drive the linkage rod 18 to pull or push the piston rod 13; During use, when the driving block 5 reciprocates in the installation cavity 103, the driving gear 15 is driven to rotate through the hinged rod 14, which drives the transmission gear 16 to rotate, and the rotation of the transmission gear 16 drives the connecting gear 17 to rotate, so that the connecting gear 17 rotates and drives the connecting rod 18 to pull or push the piston rod 13. During the process, the driving gear 15 gradually drives the transmission gear 16 and the connecting gear 17 with a smaller diameter than itself, and the large gear drives the small gear, which plays an accelerating role, increases the frequency of the connecting rod 18 driving the piston rod 13, and increases the blowing frequency of the air outlet pipe 205, which further increases the blowing effect of the airflow on the paint in the filter hole.

[0027] like Figure 7 and Figure 8As shown, in the second embodiment, a rack 19 is installed in the accommodating chamber 101, and an accommodating groove 1901 is provided on the scraper 303. A rotating gear 1902 meshing with the rack 19 is rotatably installed in the accommodating groove 1901. When the scraper 303 slides in the accommodating chamber 101, the rotating gear 1902 and the rack 19 are driven to move relative to each other, and then the rotating gear 1902 is rotated by the meshing of the rack 19 and the rotating gear 1902. A pull rope 1903 is wound around the rotating shaft of the rotating gear 1902, and a paint pushing plate 1904 is slidably installed on the scraper 303. A spring is installed between the paint pushing plate 1904 and the scraper 303. In order to facilitate the display of other components, the spring is not shown in the figure. The spring makes the paint pushing plate 1904 move in the direction of the scraper 303 close to the protrusion 202. The paint pushing plate 1904 is connected to the pull rope 1903. The paint pushing plate 1904 slides along the side close to the resistance rod 203 to the side away from the resistance rod 203. A groove body is opened on the scraper 303, and a block that slides with the groove body is installed on the paint pushing plate 1904. The block is restricted by the inner wall of the groove body so that the paint pushing plate 1904 can only slide on the scraper 303 in a straight line direction; Since the filter plate 2 only rotates in one direction, when too much paint is added at one time, the paint tends to gather more on the side of the filter plate 2 close to the protrusion 202. When the scraper plate 3 slides in the accommodating chamber 101, the pull rope 1903 is reeled in by the rotation of the rotating gear 1902, so that the paint pushing plate 1904 moves in the direction away from the protrusion 202 to push the paint so that the paint can be flattened. When the scraper plate 3 is reset, the paint pushing plate 1904 is also reset by the spring. Since the drive block 5 is in a dynamic process from the pulling end to the resistance end of the reciprocating screw 401, it takes time. During this time, the paint pushing plate 1904 can be reset before the filter plate 2 rotates again, so that each time the filter plate 2 returns to the horizontal state, the paint pushing plate 1904 is on the side of the scraper 303 close to the protrusion 202, thereby improving the feasibility of the device. Embodiment 3

[0028] like Figure 1 - Fig.12As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a shielding plate 20 is installed in the receiving groove 1901, and the shielding plate 20 is rotationally matched with the rotating shaft of the rotating gear 1902. The shielding plate 20 is located above the rotating gear 1902, and the projection of the shielding plate 20 at the bottom of the inner wall of the receiving chamber 101 completely covers the projection of the rotating gear 1902 in the same direction. The shielding plate 20 is used to shield the rotating gear 1902 to reduce the possibility of paint falling on the rotating gear 1902. The shielding plate 20 is provided with an inclined surface, and the inclined surface faces the direction away from the receiving groove 1901. Through the guidance of the inclined surface, the paint located on the shielding plate 20 falls in the direction away from the receiving groove 1901, and the shielding plate 20 is rotationally matched with the rotating shaft of the rotating gear 1902, which will not affect the rotation of the rotating gear 1902. The baffle plate 20 is provided with bristles 21 in contact with the rotating gear 1902. When the rotating gear 1902 rotates, it moves relative to the bristles 21. The brushing of the bristles 21 and the centrifugal force generated by the rotating gear 1902 itself further reduce the possibility of paint staying on the rotating gear 1902, thereby increasing the feasibility of the device.

[0029] In the third embodiment, a plug rod 22 is installed on the driving block 5, and a plug sleeve 23 that slidably cooperates with the plug rod 22 is installed on the interference rod 203. A blocking block 24 for blocking the interference rod 203 is installed in the mounting cavity 103. When the driving block 5 moves toward the pulling end of the reciprocating screw rod 401, the plug rod 22 slides in the plug sleeve 23. When the two slide to the maximum limit, the interference rod 203 and the plate body thereon slide into the mounting cavity 103. When the plate body on the interference rod 203 contacts the blocking block 24, the driving block 5 reaches the end of the pulling end. When the driving block 5 moves toward the interference end, the plug rod 22 first slides in the plug sleeve 23. When the plug rod 22 When the rod 22 is inserted into the innermost part of the insertion tube 23, the driving block 5 continues to move toward the resistance end before pushing the resistance rod 203. Through the above-mentioned arrangement, the time spent by the driving block 5 to pull the resistance rod 203 is increased, so that the resistance rod 203 can have a longer time to resist the protrusion 202, further increasing the movement time of the paint on the filter plate 2, and the resistance rod 203 is blocked by the blocking block 24, so that the plate body on the resistance rod 203 can be located at the opening of the installation cavity 103 and play a role of sealing, and will not continue to move into the installation cavity 103 to affect the operation of it and the components, thereby increasing the practicality of the device.

[0030] In the third embodiment, an inclined block 25 is installed on the installation shell 1 at the opening of the installation cavity 103. The inclined block 25 is located on the side of the installation cavity 103 opening facing the accommodating cavity 101, and the inclined surface of the inclined block 25 faces the side away from the installation cavity 103. The bottom of the inclined block 25 contacts the upper surface of the interference rod 203, and the inclined block 25 is located above the opening of the installation cavity 103. When in use, when the upper plate of the interference rod 203 moves into the installation cavity 103, the upper part of the upper plate of the interference rod 203 is scraped by the bottom of the inclined block 25, thereby reducing the possibility that the interference rod 203 drives the paint into the installation cavity 103. Moreover, through the guidance of the inclined surface of the inclined block 25, when adding paint, the paint falls on the inclined block 25 and moves in the direction away from the opening of the installation cavity 103, thereby reducing the device from entering the installation cavity 103 when adding paint. A plate body is installed on one side of the mounting shell 1 through a hinge, and the accommodating cavity 101 is shielded by the plate body. When the device is used for a long time, the accommodating cavity 101 is exposed by opening the plate body, which facilitates cleaning of the components in the accommodating cavity 101 and the filter plate 2, thereby increasing the practicability of the device.
