A primary-secondary integrated complete ring main unit with dust removal function

Abstract

The present invention discloses a primary and secondary integrated complete ring network cabinet with a dust removal function, belonging to the technical field of ring network cabinets. When the sleeve is pressed down under an external force and descends, the end of the sleeve contacts and presses the first spring, and the first spring undergoes elastic deformation. When the thrust that presses down the sleeve dissipates, the elastic deformation of the first spring recovers and generates a thrust to push the lower connecting plate upward and rotate. The lower connecting plate cooperates with the upper connecting plate to twist the hydrophobic filter screen. When the hydrophobic filter screen is twisted, it will exert a squeezing effect on the wet dust layer. This squeezing helps to remove the moisture therein, weakening the binding force between the dust particles. At the same time, twisting the hydrophobic filter screen will also cause the dust layer to be subjected to a shear force. When the acting force is greater than the binding force between the dust particles or between the dust particles and the hydrophobic filter screen, the dust layer will peel off and fall off from the surface of the filter bag.

Description

Technical Field

[0001] The present invention relates to the technical field of ring main unit cabinets, and in particular to a primary-secondary integrated complete set of ring main unit cabinets with a dust removal function. Background Art

[0002] A primary-secondary integrated complete set of ring main unit cabinets is an intelligent power equipment that integrates power distribution, protection, control, and automation functions. Its core design concept is to highly integrate traditional primary equipment (such as ring main unit cabinets, instrument transformers, etc.) and secondary equipment (such as measurement and control units, protection devices, etc.) to form a standardized and modular whole, achieving the integrated goal of power distribution, status monitoring, fault handling, and remote control;

[0003] The primary-secondary integrated complete set of ring main unit cabinets is commonly used in urban power grids, industrial parks, large buildings and other places. The environmental conditions in these places may be relatively complex, and the dust pollution is relatively serious. The accumulation of dust may cause poor heat dissipation of the equipment, a decrease in insulation performance, and even cause faults such as short circuits, affecting the safe and stable operation of the power grid. Installing dust removal equipment can ensure that the ring main unit cabinet can also operate stably in a complex environment, reduce faults and power outages caused by environmental factors, help reduce equipment wear and failure rates, and extend the service life of the equipment;

[0004] During actual use, when the air humidity is relatively high, the condensation in the ring main unit cabinet may cause a short circuit between two secondary wires on the terminal block. If it happens to be the switch trip circuit, it will immediately cause the switch to malfunction and cause a power outage accident. Therefore, a hydrophobic filter bag can be selected to block water molecules in the air. However, after the dust particles come into contact with water molecules, their surfaces are prone to adsorb water and form a wet dust layer. This wet dust layer is not easily captured by the dust collector and is prone to clogging the filter bag of the dust collector, affecting normal ventilation and dust removal effects. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that when a hydrophobic filter bag blocks water molecules in the air, dust is prone to adsorb water and form a wet dust layer. This wet dust layer is not easily captured by the dust collector and is prone to clogging the filter bag of the dust collector, affecting normal ventilation and dust removal effects, and to propose a primary-secondary integrated complete set of ring main unit cabinets with a dust removal function.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solution: a primary-secondary integrated complete set of ring main unit cabinets with a dust removal function:

[0007] It includes a ring main unit cabinet body and a cooling fan installed on the ring main unit cabinet body. A gas supply mechanism is installed on the cooling fan. The gas supply mechanism includes a housing arranged in the ring main unit cabinet body and a cover body installed on the housing and connected to the cooling fan. An air inlet and an air outlet are opened on the cover body;

[0008] A dust removal mechanism is provided in the housing. The dust removal mechanism includes a filter cartridge disposed at the air outlet and a filter disposed within the filter cartridge. The filter includes a lower connecting plate movably installed within the filter cartridge and an upper connecting plate fixedly installed. An annular hydrophobic filter screen for blocking the wet dust layer is provided at the edges of the lower connecting plate and the upper connecting plate.

[0009] A torsion mechanism is provided at the bottom of the filter cartridge. The torsion mechanism includes a mounting plate that can rotate and rise at the bottom of the lower connecting plate. When the mounting plate pushes the lower connecting plate to rise and rotate, it cooperates with the upper connecting plate to twist the hydrophobic filter screen, and the wet dust layer within the hydrophobic filter screen is squeezed to dehydrate and peeled off from the hydrophobic filter screen.

[0015] The torsion mechanism further includes a base installed at the bottom of the filter cartridge and a sleeve rotatably connected to the mounting plate. A first spring that fits with the sleeve is installed in the middle of the base.

[0017] The torsion mechanism further includes a guide installed on the lower connecting plate and a guiding groove opened on the inner wall of the filter cartridge.

[0023] A plurality of buckle mechanisms are arranged on the base. The buckle mechanism includes a plurality of first chutes opened on the installation ring and an annular card slot opened on the sleeve. A rotating shaft is slidably embedded in the first chute;

[0024] An installation frame is sleeved and installed on the surface of the rotating shaft. A hook is installed at the end of the installation frame, which abuts against the card slot and can only rotate towards the side close to the rotating shaft. After the hook abuts against the card slot, the rotating shaft slides in the first chute to pull the sleeve down, reducing the distance between the sleeve and the water storage cavity and simultaneously squeezing the first spring;

[0025] A pressing plate is installed on the other side of the installation frame. Pressing down the pressing plate makes the installation frame rotate around the rotating shaft to release the abutment between the hook and the card slot.

[0026] As a further description of the above-mentioned technology, a primary-secondary integrated complete ring main cabinet with dust removal function:

[0027] Torsion springs are arranged in both the installation frame and the hook;

[0028] The torsion spring in the installation frame makes the installation frame rotate around the rotating shaft and then reset;

[0029] The torsion spring in the hook makes the hook rotate towards the rotating shaft side under the extrusion of the sleeve and then reset to a horizontal state.

[0030] As a further description of the above-mentioned technology, a primary-secondary integrated complete ring main cabinet with dust removal function:

[0031] An unlocking mechanism is arranged on the installation ring. The unlocking mechanism includes a second chute opened on the installation ring. A sliding table is slidably embedded in the second chute, and a second spring is arranged at the bottom of the sliding table;

[0032] A bracket and a guiding plate penetrating through the second chute are installed on the sliding table. A bearing pressing plate that fits the inner wall of the water storage cavity is installed on the bracket, and a positioning pin penetrating through the guiding plate is arranged on the installation frame;

[0033] When the guiding plate presses down the positioning pin, it pushes the rotating shaft to slide in the first chute, causing the hook to pull the sleeve down. When the installation frame rotates, the positioning pin moves along the inner wall track of the guiding plate.

[0034] As a further description of the above-mentioned technology, a primary-secondary integrated complete ring main cabinet with dust removal function:

[0035] The unlocking mechanism further comprises an abutment rod and a telescopic rod arranged on the mounting ring, the abutment rod passes through the mounting ring and the telescopic rod passes through the pressure plate;

[0036] A floating ball is arranged on the abutment rod, and when water is stored in the water storage chamber, the abutment rod floats up through the floating ball;

[0037] After the accumulated water stored in the water storage chamber is discharged through the drainage groove at the bottom, the abutting rod descends and abuts against the telescopic rod, and the telescopic rod contracts under the push of the abutting rod.

[0038] As a further description of the above technology, a one-two fusion ring net box with dust removal function:

[0039] A closing mechanism is provided between the cover body and the air inlet cylinder and the filter cylinder, the closing mechanism comprising a second grid net provided in the air inlet cylinder and a first grid net provided in the filter cylinder, the second grid net and the first grid net are both provided with countersunk holes, a movable rod is movably embedded in the countersunk hole, and the movable rod is connected to the countersunk hole through a third spring;

[0040] A closed grid net for closing the inlet and outlet of the shell is installed at the top of the movable rod, and a push rod is installed in the air inlet and the air outlet. When the cover body is combined with the shell, the push rod pushes the closed grid net to move, so that the closed grid net enters the air inlet cylinder or the filter cylinder cavity to release the seal.

[0041] In summary, due to the use of the above-mentioned technology, a one- and two-stage fusion ring network box with dust removal function has the following beneficial effects:

[0042] 1. Through the dust removal mechanism, after the unfiltered air is introduced into the air inlet through the air inlet, the entrained larger dust particles and debris can be intercepted by the air inlet and collected in the dust collecting chamber arranged at the bottom of the shell. The inner wall of the dust collecting chamber is set to a cone to guide the dust particles and debris to concentrate. At the same time, the air enters the filter cylinder through the opening at the bottom of the filter cylinder, and enters the hydrophobic filter through the opening at the bottom of the lower connecting plate. Under the interception of the hydrophobic filter, the dust and moisture in the air are blocked by the hydrophobic filter. Under the action of gravity, the dust and water are separated from the hydrophobic filter and enter the dust collecting chamber. At this time, the dust-free dry air can pass through the hydrophobic filter and be discharged from the opening at the top of the filter cylinder. The air is led out of the shell through the air outlet, and the dust removal and dehumidification of the air are completed;

[0043] 2. Through the provided torsion mechanism, when the sleeve is pressed downwards under an external force and descends, the end of the sleeve contacts and compresses the first spring, causing the first spring to undergo elastic deformation. When the thrust that presses down the sleeve dissipates, the elastic deformation of the first spring recovers and generates a thrust to push the lower connecting plate upwards and rotate. The lower connecting plate cooperates with the upper connecting plate to twist the hydrophobic filter screen. When the hydrophobic filter screen is twisted, it will exert a squeezing effect on the wet dust layer. This squeezing helps to remove the moisture therein, weakening the bonding force between the dust particles. At the same time, twisting the hydrophobic filter screen will also cause the dust layer to be subjected to a shear force. When the force is greater than the bonding force between the dust particles or between the dust particles and the hydrophobic filter screen, the dust layer will peel off and fall from the surface of the filter bag. Moreover, the greater the deformation of the hydrophobic filter screen, the easier it is for the dust layer attached to the hydrophobic filter screen to fall off. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] The following will clearly and completely describe a primary-secondary integrated complete loop network cabinet with a dust removal function in the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0071] In order to solve the problem that when a hydrophobic filter bag blocks water molecules in the air, dust is easy to adsorb moisture and form a wet dust layer, this wet dust layer is not easily captured by the dust collector and is easy to block the filter bag of the dust collector, affecting the normal ventilation and dust removal effect, the present invention proposes a primary-secondary integrated complete loop network cabinet with a dust removal function, as Figure 1 - Figure 18 shown:

[0072] It includes a loop network cabinet body 11 and a heat dissipation fan 12 installed on the loop network cabinet body 11. A gas supply mechanism 20 is installed on the heat dissipation fan 12. The gas supply mechanism 20 includes a housing 21 arranged in the loop network cabinet body 11 and a cover body 22 installed on the housing 21 and connected to the heat dissipation fan 12. An air inlet 221 and an air outlet 222 are provided on the cover body 22. When the heat dissipation fan 12 is started, air is inhaled, so that the air enters the housing 21 through the air inlet 221. After filtering the moisture and dust in the air, it is then introduced into the loop network cabinet body 11 through the air outlet 222;

[0073] In order to be able to filter moisture and dust, as Figure 3 and Figure 7 shown, a dust removal mechanism 30 is arranged in the housing 21. The dust removal mechanism 30 includes a filter cylinder 32 arranged at the air outlet 222 and a filter 33 arranged in the filter cylinder 32. The filter 33 includes a lower connecting plate 331 movably installed in the filter cylinder 32 and an upper connecting plate 332 fixedly installed. An annular hydrophobic filter screen 334 for blocking the wet dust layer is arranged at the edges of the lower connecting plate 331 and the upper connecting plate 332. The lower connecting plate 331 and the upper connecting plate 332 are connected by a rotating telescopic rod 333;

[0074] After the unfiltered air is introduced into the intake cylinder 31 through the air inlet 221, the larger dust particles and debris carried by it can be intercepted by the intake cylinder 31 and collected in the dust collection chamber 211 provided at the bottom of the housing 21. The inner wall of the dust collection chamber 211 is set to be conical to guide the concentration of dust particles and debris. At the same time, the air enters the filter cylinder 32 through the opening at the bottom of the filter cylinder 32 and enters the hydrophobic filter screen 334 through the opening at the bottom of the lower connecting plate 331. Under the interception of the hydrophobic filter screen 334, the dust and moisture in the air are blocked by the hydrophobic filter screen 334. Under the action of gravity, the dust and water separate from the hydrophobic filter screen 334 and enter the dust collection chamber 211. At this time, the dust-free dry air can pass through the hydrophobic filter screen 334 and be discharged from the opening at the top of the filter cylinder 32. The air is led out of the housing 21 through the air outlet 222, and the dust removal and dehumidification operations of the air are completed.

[0075] Furthermore, in order to increase the residence time of the air in the filter cylinder 32 and improve the filtering effect of the filter 33, as Figure 4 and Figure 18 shown, the dust removal mechanism 30 further includes an intake cylinder 31 provided in the housing 21 and communicating with the air inlet 221. The bottom of the intake cylinder 31 is provided with an opening and both the intake cylinder 31 and the filter cylinder 32 are set to be cylindrical. The inner diameter of the intake cylinder 31 is smaller than that of the filter cylinder 32;

[0076] A closing plate 34 for filling the gap between the intake cylinder 31 and the filter cylinder 32 is provided in the housing 21;

[0077] Through this design, after the air is discharged from the intake cylinder 31, it can only enter the filter cylinder 32 under the blockage of the closing plate 34. And since the opening of the filter cylinder 32 is larger than that of the intake cylinder 31, and the size of the opening will directly affect the air velocity at the opening. Therefore, the larger opening will slow down the air velocity when the air flows through. At the same time, because the same volume of air can flow out on a larger opening area, resulting in a slower flow velocity, and at the same time increasing the amount of air flowing through per unit time. Therefore, compared with the setting method where the diameters of the intake cylinder 31 and the filter cylinder 32 are the same, the setting method where the diameter of the filter cylinder 32 is larger and the diameter of the intake cylinder 31 is smaller can make the air pass through the intake cylinder 31 quickly, and more air enters the filter cylinder 32 and can stay for a longer time.

[0078] In order to be able to remove the wet dust layer formed by the mixture of dust and moisture in the hydrophobic filter screen 334, a twisting mechanism 40 is provided at the bottom of the filter cylinder 32, as Figure 8 、 Figures 10 - 13 shown, the twisting mechanism 40 includes a mounting plate 41 that can rotate and rise and is mounted at the bottom of the lower connecting plate 331;

[0079] The torsion mechanism 40 further includes a base 44 installed at the bottom of the filter cartridge 32 and a sleeve 42 rotatably connected to the mounting plate 41. A first spring 45 that fits with the sleeve 42 is installed in the middle of the base 44. When the sleeve 42 is pressed down and descends under an external force, the end of the sleeve 42 contacts and squeezes the first spring 45, causing the first spring 45 to undergo elastic deformation. When the thrust that presses down the sleeve 42 dissipates, the elastic deformation of the first spring 45 recovers and generates a thrust to push the lower connecting plate 331 upward and rotate. The lower connecting plate 331 cooperates with the upper connecting plate 332 to twist the hydrophobic filter screen 334. When the hydrophobic filter screen 334 is twisted, it will exert a squeezing effect on the wet dust layer. This squeezing helps to remove the moisture therein, weakening the binding force between the dust particles. At the same time, twisting the hydrophobic filter screen 334 will also cause the dust layer to be subjected to a shear force. When the acting force is greater than the binding force between the dust particles or between the dust particles and the hydrophobic filter screen 334, the dust layer will peel off and fall from the surface of the filter bag. Moreover, the greater the deformation of the hydrophobic filter screen 334, the easier the dust layer attached to the inside of the hydrophobic filter screen 334 is to fall off;

[0080] Therefore, in order to enable the hydrophobic filter screen 334 to increase its deformation through rotation, as Figure 11 and Figure 12 shown, the torsion mechanism 40 further includes a guide 43 installed on the lower connecting plate 331 and a guiding groove 46 opened on the inner wall of the filter cartridge 32. The guide 43 includes a mounting seat 431 connected to the bottom of the lower connecting plate 331, a ball mounting cavity 432 installed on the mounting seat 431, and balls 433 embedded in the ball mounting cavity 432. The balls 433 are all in rolling fit with the guiding groove 46;

[0081] During the process of the mounting plate 41 pushing the lower connecting plate 331 upward, it will also drive the ball mounting cavity 432 to move in the guiding groove 46 through the mounting seat 431. The balls 433 embedded in the ball mounting cavity 432 roll while fitting with the guiding groove 46. Under the guidance of the guiding groove 46, the mounting plate 41 can rise and rotate along the trajectory of the guiding groove 46. Since the upper connecting plate 332 is fixedly arranged, the lower connecting plate 331 can rotate while being restricted and guided by the rotating telescopic rod 333, and at the same time, by rising and reducing the distance from the upper connecting plate 332, the torsion of the hydrophobic filter screen 334 is realized, and the deformation of the hydrophobic filter screen 334 increases.

[0082] In order to enable the sleeve 42 to be pressed down by an external force, the base 44 includes a positioning seat 441 detachably installed at the bottom of the filter cartridge 32 and a spring mounting groove 443 installed on the positioning seat 441. A water storage cavity 442 is arranged on the outer edge of the spring mounting groove 443, and a mounting ring 444 is arranged between the water storage cavity 442 and the spring mounting groove 443;

[0083] The bottom of the first spring 45 is installed in the middle of the spring mounting groove 443;

[0084] The height of the water storage cavity 442 is lower than that of the mounting ring 444, and a drain groove is provided on the water storage cavity 442;

[0085] A plurality of buckle mechanisms 50 are provided on the base 44. The buckle mechanism 50 includes a plurality of first sliding grooves 51 provided on the water storage cavity 442 and an annular clamping groove 56 provided on the sleeve 42. A rotating shaft 52 is slidably embedded in the first sliding groove 51;

[0086] An installation frame 53 is sleeved and installed on the surface of the rotating shaft 52. A hook 54 that abuts against the clamping groove 56 and can only rotate towards the side close to the rotating shaft 52 is installed at the end of the installation frame 53. After the hook 54 abuts against the clamping groove 56, the rotating shaft 52 slides in the first sliding groove 51 to pull the sleeve 42 down, reducing the distance between the sleeve 42 and the spring installation groove 443 to squeeze the first spring 45;

[0087] A pressing plate 55 is installed on the other side of the installation frame 53. Pressing down the pressing plate 55 causes the installation frame 53 to rotate around the rotating shaft 52 to release the abutment between the hook 54 and the clamping groove 56;

[0088] Torsion springs are provided in both the installation frame 53 and the hook 54;

[0089] As Figure 8 shown, when a wet dust layer is formed in the hydrophobic filter screen 334, the overall weight of the hydrophobic filter screen 334 increases. Since the hydrophobic filter screen 334 is conical, the lower connecting plate 331 at the bottom sags after the weight increases. The lower connecting plate 331 pushes the sleeve 42 down through the mounting plate 41 and abuts against the first spring 45. At the same time, the guide 43 drives the mounting plate 41 to reverse under the guidance of the guide groove 46, and the lower connecting plate 331 drives the hydrophobic filter screen 334 to twist in the opposite direction. When the sleeve 42 contacts the hook 54, it can push the hook 54 to rotate until it separates from the hook 54. The torsion spring in the hook 54 causes the hook 54 to rotate towards the rotating shaft 52 side under the extrusion of the sleeve 42 and then reset to a horizontal state. The hook 54 can be snapped into the clamping groove 56. At the same time, the hook 54 can also cooperate with the clamping groove 56 to limit the sleeve 42 so that it no longer rotates with the mounting plate 41, completing the connection between the installation frame 53 and the sleeve 42. Under the restriction of the hook 54, the sleeve 42 cannot be bounced up by the first spring 45;

[0090] An unlocking mechanism 60 is provided on the mounting ring 444. The unlocking mechanism 60 includes a second sliding groove 61 provided on the spring installation groove 443. A sliding table 62 is slidably embedded in the second sliding groove 61, and a second spring 63 is provided at the bottom of the sliding table 62;

[0091] A support 64 and a guide plate 66 that penetrate the second sliding groove 61 are installed on the sliding table 62. A bearing plate 65 that fits against the inner wall of the water storage cavity 442 is installed on the support 64. A positioning pin 67 that penetrates the guide plate 66 is provided on the installation frame 53;

[0092] When the guide plate 66 presses down the positioning pin 67, it pushes the rotating shaft 52 to slide in the first chute 51, causing the hook 54 to pull the sleeve 42 downwards;

[0093] As Figure 9 shown, through this design, the water intercepted by the hydrophobic filter screen 334 can converge in the chamber formed by the combination of the water storage chamber 442 and the bearing plate 65. As the water volume increases, the bearing plate 65 gradually descends and pulls the sliding table 62 through the bracket 64. The sliding table 62 descends in the second chute 61 and squeezes the second spring 63 to cause elastic deformation. At the same time, the sliding table 62 pulls the mounting frame 53 downwards through the guide plate 66 and the positioning pin 67, enabling the mounting frame 53 to cooperate with the hook 54 and the clamping groove 56 to pull the sleeve 42 downwards. At the same time, the mounting frame 53 drives the rotating shaft 52 to descend under the limitation of the first chute 51 until the bearing plate 65 reaches the lowest point of the water storage chamber 442. At this time, the accumulated water stored in the water storage chamber 442 is discharged through the drainage groove at the bottom;

[0094] Meanwhile, the unlocking mechanism 60 further includes an abutting rod 68 and a telescopic rod 69 arranged on the mounting ring 444. The abutting rod 68 penetrates through the mounting ring 444 while the telescopic rod 69 penetrates through the pressing plate 55;

[0095] One end of the abutting rod 68 located in the water storage chamber 442 is provided with a floating ball 681. When the water storage chamber 442 stores water, it floats through the floating ball 681. After the accumulated water stored in the water storage chamber 442 is discharged through the drainage groove at the bottom, the abutting rod 68 descends and abuts against the telescopic rod 69. Under the push of the abutting rod 68, the telescopic rod 69 contracts and presses down the pressing plate 55. The pressing plate 55 pushes the mounting frame 53 to rotate to release the abutment between the hook 54 and the clamping groove 56. At the same time, the mounting frame 53 drives the positioning pin 67 to move along the inner wall track of the guide plate 66, and the restriction of the hook 54 cooperating with the clamping groove 56 on the sleeve 42 is released. At this time, the thrust generated by the elastic deformation recovery of the first spring 45 pushes the sleeve 42 upwards, thereby achieving the purpose of periodically twisting the hydrophobic filter screen 334 to remove the moist dust layer attached inside the hydrophobic filter screen 334;

[0096] The torsion spring in the mounting frame 53 causes the mounting frame 53 to reset after rotating with the rotating shaft 52 as the axis;

[0097] When there is not enough water stored in the water storage chamber 442, the abutting rod 68 cannot float. At this time, the abutting rod 68 abuts against the telescopic rod 69 under the action of gravity and pushes the pressing plate 55, causing the pressing plate 55 to drive the mounting frame 53 to maintain a deflected state with the rotating shaft 52 as the axis. At this time, the hook 54 does not contact the sleeve 42 and the clamping groove 56, so it will not interfere with the downward movement of the sleeve 42;

[0098] When the water storage cavity 442 is refilled with water and the abutting rod 68 floats up, the abutting rod 68 no longer abuts against the telescopic rod 69 to limit the position of the pressing plate 55. At this time, the mounting bracket 53 pulls the telescopic rod 69 to recover through the pressing plate 55, and the mounting bracket 53 drives the hook 54 to engage with the card slot 56.

[0099] As Figures 15 - 17 shown, in order to prevent the internal accumulated water and debris from leaking when the cover 22 is removed to clean the internal air inlet 221 and replace the filter 33, a sealing mechanism 70 is provided between the cover 22, the air inlet cylinder 31 and the filter cylinder 32. The sealing mechanism 70 includes a second grid 76 provided in the air inlet cylinder 31 and a first grid 71 provided in the filter cylinder 32. Sinking holes 72 are provided on both the second grid 76 and the first grid 71. A movable rod 74 is movably embedded in the sinking hole 72, and the movable rod 74 is connected to the sinking hole 72 through a third spring 73.

[0100] A sealing grid 75 for closing the inlet and outlet of the housing 21 is installed at the top of the movable rod 74. A push rod 77 is installed in the air inlet 221 and the air outlet 222. When the cover 22 and the housing 21 are combined, the push rod 77 pushes the sealing grid 75 to move, so that the sealing grid 75 enters the cavity of the air inlet cylinder 31 or the filter cylinder 32. The sealing grid 75 drives the movable rod 74 to move in the sinking hole 72 and squeezes the third spring 73 to cause elastic deformation. At this time, air enters through the sealing grid 75 in the air inlet cylinder 31, reaches the air inlet cylinder 31 after passing through the first grid 71. The air in the filter cylinder 32 passes through the first grid 71 and then is discharged from the filter cylinder 32 through the sealing grid 75. When the push rod 77 moves out of the sealing grid 75, the sealing grid 75 closes the openings at the tops of the air inlet cylinder 31 and the filter cylinder 32 under the push of the elastic deformation recovery of the third spring 73.

[0101] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
