Description

Technical Field

[0001] The present invention relates to the technical field of air compression, and in particular to an air compressor. Background Art

[0002] As a commonly used air compression device, the core function of a piston air compressor is to effectively compress gas to a high pressure through the vertical reciprocating motion of the piston, allowing it to be used by other equipment or systems. Specifically, when the piston moves downward, negative pressure forms inside the cylinder, causing external gas to be drawn into the cylinder through the intake valve. Subsequently, the piston moves upward, compressing the gas within the cylinder. During this process, the intake and exhaust valves are opened and closed at the appropriate time to ensure that the gas is effectively compressed to the preset pressure. Finally, the fully compressed gas is smoothly discharged through the exhaust port for subsequent use.

[0003] In the actual application of air compressors, when the piston performs reciprocating up and down motion, the piston will frequently contact the inner wall of the cylinder. At the same time, the gas entering the cylinder will also produce dynamic impact on the piston. Under the interaction of these factors, the outer wall of the piston will gradually deform or even be damaged.

[0004] In response to the above problems, Chinese patent application number 202410277590.6 discloses an energy-saving air compressor, which specifically relates to the field of gas compression machinery manufacturing, including a gas storage tank body, a lifting frame fixedly connected to the top of the gas storage tank body, an air compression mechanism fixedly connected to the top of the lifting frame, a driving mechanism fixedly connected to one side of the lifting frame, and the air compression mechanism including a crankcase fixedly connected to the top of the lifting frame, a cylinder body connected to the top of the crankcase, a top cover fixedly connected to the top of the cylinder body, an air inlet pipe connected to one side of the outer wall of the top cover, an air outlet pipe connected to the gas storage tank body connected to the other side of the outer wall of the top cover, and a sealing gasket fixedly connected to the connection between the top cover and the cylinder body. The air compressor is provided with multiple second slides and sealing blocks that can be adjusted for horizontal displacement, so that the impact position of the multiple sealing blocks with the gas can be changed and adjusted, thereby avoiding the piston assembly from being deformed and damaged by the impact of gas for a long time, thereby causing the problem of air leakage.

[0005] In summary, although the current patent has alleviated the deformation and damage problems of the piston assembly caused by long-term gas impact to a certain extent by adjusting the relative position of the sealing block, it still faces challenges in actual application scenarios. Specifically, the sealing block designed in this patent is located on the piston plate, and its movement direction is from the center to the periphery. This movement mode has an inherent defect, that is, as the sealing block moves, the gap between adjacent sealing blocks will gradually expand. This phenomenon will directly cause the compressed gas inside the cylinder to leak through the ever-expanding gap, thereby affecting the sealing performance and overall efficiency between the piston and the cylinder.

[0006] Furthermore, when operating outdoors, air compressors inhale large amounts of air laden with impurities such as dust, sand, moisture, grease, and dirt. If these impurities are not effectively filtered, they can cause significant damage to the equipment. Therefore, air compressors are equipped with filters to remove these impurities. However, regular filter cleaning or replacement is a cumbersome process, requiring disassembly and removal of the filter element. Because the filter element is typically sealed, operators struggle to assess its internal condition and maintain timely cleaning. This reduces the compressor's intake and exhaust volumes, lowering operating efficiency. In severe cases, the filter element can break, allowing impurity-laden air to enter the cylinder, causing wear on the cylinder and piston, leading to high temperatures and even burn-out, significantly shortening the equipment's lifespan.

[0007] In view of this, it is particularly critical and urgent to develop an air compressor that can effectively deal with the above technical difficulties. Summary of the Invention

[0046] 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.

[0047] Example 1

[0048] Reference Figures 1 to 10 As shown, this embodiment provides an air compressor, including a support 1 and a driving device 4. A mounting frame 3 is provided above the support 1, and the driving device 4 is provided on the outside of the mounting frame 3.

[0049] The cylinder device 5 includes a cylinder body 501 arranged on the top of the mounting frame 3, a piston device 6 is provided inside the cylinder body 501, a baffle assembly 502 for gas to enter and exit the cylinder body 501 is provided on the top of the cylinder body 501, and a cylinder cover assembly 503 is provided above the baffle assembly 502.

[0050] When the driving device 4 is in operation, the piston device 6 reciprocates inside the cylinder 501. During the movement of the piston device 6, external gas is drawn into the interior of the cylinder 501 and the gas is compressed to a high-pressure state.

[0051] The gas storage device 2 includes a gas tank 201 arranged above the support 1. A connecting air pipe 202 is provided on the outside of the gas tank 201. The other end of the connecting air pipe 202 is connected to the cylinder head assembly 503 through a connecting joint 203.

[0052] The gas compressed to a high-pressure state enters the interior of the gas tank 201 through the gas connecting pipe 202 on the cylinder head assembly 503 to be used later.

[0053] Reference Figures 5 to 9 As shown, the partition assembly 502 includes a mounting plate 5021, which is arranged on the top of the cylinder body 501. A dividing line is provided in the middle of the mounting plate 5021, which divides the mounting plate 5021 into an air inlet and an air outlet.

[0054] The air inlet hole 5022 is provided at the air inlet portion of the mounting plate 5021 , and a first one-way valve 5024 is provided at the bottom of the air inlet hole 5022 .

[0055] The air outlet hole 5023 is provided at the air outlet portion of the mounting plate 5021 , and a second one-way valve 5025 is provided at the top of the air outlet hole 5023 .

[0056] When the piston device 6 performs a downward movement, negative pressure is formed inside the cylinder body 501 , forcing external air to enter the cylinder body 501 through the air inlet hole 5022 .

[0057] When the piston device 6 performs an upward movement, the piston device 6 compresses the gas inside the cylinder body 501 . During this process, the gas outlet 5023 opens, and the compressed gas enters the gas tank 201 through the connecting gas pipe 202 .

[0058] The first one-way valve 5024 and the second one-way valve 5025 are both elastic steel sheets. Under normal circumstances, the elastic steel sheets block the air inlet 5022 and the air outlet 5023 respectively.

[0059] Reference Figures 3 to 9 As shown, the cylinder head assembly 503 includes a cylinder head 5031, which is arranged on the top of the mounting plate 5021, and an air intake channel 5034 is provided on the top of the cylinder head. A silencer filter 9 is provided at the air intake channel 5034, and an air outlet channel 5035 is provided on the outside of the cylinder head. The air outlet channel 5035 is connected to the connecting joint 203.

[0060] The air intake chamber 5032 and the air outlet chamber 5033, the interior of the cylinder head 5031 is provided with a partition plate, the partition plate is fitted with the top of the mounting plate 5021, and the partition plate divides the interior of the cylinder head 5031 into the air intake chamber 5032 and the air outlet chamber 5033, the air intake chamber 5032 corresponds to the air intake hole 5022, and the air outlet chamber 5033 corresponds to the air outlet hole 5023.

[0061] Reference Figures 3 to 5 As shown, the driving device 4 includes a driving member 401, which is arranged on the outside of the mounting frame 3 and is used to provide power for the piston device 6 to move.

[0062] The driven wheel 402 is disposed below the cylinder body 501 and is rotationally connected to the mounting frame 3 ; it is connected to the output shaft of the driving member 401 via a transmission belt 403 .

[0063] The eccentric shaft 404 is arranged at an eccentric position of the driven wheel 402 , and one end of the eccentric shaft 404 away from the driven wheel 402 is connected to the piston device 6 .

[0064] The driving member 401 includes a motor, which is fixedly connected to the mounting bracket 3 , and an output end of the motor is connected to the driven wheel 402 via a transmission belt 403 .

[0065] Reference Figures 1 to 3 As shown, a power supply device 8 is provided on the outside of the gas tank 201 . The power supply device 8 includes a control assembly 801 , which is arranged on the outside of the gas tank 201 and has a switch 802 for controlling the start and stop of the driving device 4 .

[0066] The protective shell 803 is arranged on the outside of the gas tank 201, and a battery compartment 804 is provided inside the protective shell. A battery pack for providing electrical energy is provided inside the battery compartment 804.

[0067] Specifically, a support elbow is provided on the outside of the support 1, and a handle is installed on the transverse outer wall of the support elbow. The support elbow and the handle are provided to facilitate the movement of the air compressor.

[0068] During use, the switch 802 is pressed to start the air compressor, and the battery pack provides electrical energy to the air compressor, thereby causing the driving member 401 to rotate. During the rotation of the driving member 401, the driven wheel 402 is driven to rotate through the transmission belt 403, and the driven wheel 402 drives the eccentric shaft 404 to rotate eccentrically, so that the eccentric shaft 404 drives the piston device 6 to move back and forth up and down inside the cylinder body 501.

[0069] When the piston assembly 6 moves downward, the interior of the cylinder 501 is in a negative pressure state. Under the influence of the negative pressure, the first one-way valve 5024 gradually opens. At the same time, the external air is affected by the negative pressure and filtered by the silencer filter 9. Then, it enters the air intake chamber 5032 through the air intake channel 5034. The air entering the air intake chamber 5032 enters the interior of the cylinder 501 through the air intake hole 5022.

[0070] It should be noted that, since the second one-way valve 5025 is located above the air outlet 5023 , the second one-way valve 5025 will not open when the piston device 6 moves downward.

[0071] As the piston assembly 6 moves upward, it compresses the air within the cylinder 501, gradually increasing the pressure within the cylinder 501. When the air is compressed to a set value, the second one-way valve 5025 gradually opens under the influence of the pressure. The compressed air then flows through the air outlet 5023 and the second one-way valve 5025 into the air outlet chamber 5033. The compressed air in the air outlet chamber 5033 then flows through the air connecting pipe 202 into the interior of the gas tank 201.

[0072] It should be noted that: since the first one-way valve 5024 is located below the air inlet hole 5022, the first one-way valve 5024 will not open when the piston device 6 moves upward.

[0073] Example 2

[0074] Although the above embodiment has successfully achieved the function of compressed air, in actual application scenarios, the piston device 6 will frequently come into contact with the inner wall of the cylinder 501 when it continues to perform reciprocating up and down motions. At the same time, the gas entering the cylinder 50 will also produce a strong dynamic impact on the piston. The combined effect of these factors will gradually increase the gap between the piston device 6 and the cylinder 501. This change will inevitably cause the compressed gas inside the cylinder 501 to leak through the increasingly widening gap, thereby seriously affecting the sealing performance between the piston and the cylinder 50 and the operating efficiency of the entire system. In view of this, technical improvements are made on the basis of Example 1, and the improved technical solution is as follows: With reference to Figures 5 to 10As shown, the piston device 6 includes an articulated seat 601 arranged on the cylinder body 501, the articulated seat 601 is connected to the output end of the driving device 4, a connecting seat 602 is provided on the top of the articulated seat 601, and a first movable part 603 and a second movable part 604 with freely adjustable diameters are respectively provided at the upper and lower ends of the connecting seat 602.

[0075] One end of the eccentric shaft 404 is hinged to the hinge seat 601 , and the other end is rotatably connected to the eccentric position of the driven wheel 402 .

[0076] Reference Figures 8 and 9 As shown, the first movable member 603 includes a first connecting plate 6031 disposed above the connecting seat 602 , a first elastic member 6032 is disposed between the first connecting plate 6031 and the connecting seat 602 , and the first elastic member 6032 is located around the first connecting plate 6031 .

[0077] The first elastic member 6032 includes an annular ring, one end of the annular ring is fixedly connected to the first connecting plate 6031 , and the other end of the annular ring is fixedly connected to the first connecting plate 6031 .

[0078] When the distance between the first connecting plate 6031 and the connecting seat 602 is reduced, the space between them is gradually compressed, and the first elastic member 6032 gradually expands.

[0079] When the distance between the first connecting plate 6031 and the connecting seat 602 increases, the space between them is gradually increased, and the first elastic member 6032 gradually contracts.

[0080] A first telescopic member 6033 is provided between the first connecting plate 6031 and the connecting seat 602 . The first telescopic member 6033 is located in the middle of the first connecting plate 6031 .

[0081] The first telescopic member 6033 comprises a first elastic telescopic tube. A magnetic block is installed at the connection between the first elastic telescopic tube and the connecting base 602, and a first electromagnetic block is installed at the connection between the first elastic telescopic tube and the first connecting plate 6031. By controlling the magnitude and direction of the current flowing into the electromagnetic block, the first connecting plate 6031 can be controlled to move up and down, thereby adjusting the distance between the first connecting plate 6031 and the connecting base 602.

[0082] It should be noted that: in this embodiment, the first elastic telescopic tube can only be axially extended and retracted up and down.

[0083] Reference Figures 8 and 9 As shown, the second movable member 604 includes a second connecting plate 6041 provided below the connecting seat 602 , and the second connecting plate 6041 is slidably connected to the hinge seat 601 .

[0084] A second elastic member 6042 is provided between the second connecting plate 6041 and the connecting seat 602 . The second elastic member 6042 is located around the second connecting plate 6041 .

[0085] The second elastic member 6042 includes an annular ring, one end of which is fixedly connected to the second connecting plate 6041 ; the other end of the annular ring is fixedly connected to the second connecting plate 6041 .

[0086] When the distance between the second connecting plate 6041 and the connecting seat 602 is reduced, the space between them is gradually compressed, and the second elastic member 6042 gradually expands.

[0087] When the distance between the second connecting plate 6041 and the connecting seat 602 increases, the space between the two is gradually increased, and the second elastic member 6042 gradually contracts.

[0088] A second telescopic member 6043 is provided between the second connecting plate 6041 and the connecting seat 602 . The second telescopic member 6043 is located in the middle of the second connecting plate 6041 .

[0089] The second telescopic member 6043 comprises a second elastic telescopic tube. A magnetic block is installed at the connection between the second elastic telescopic tube and the connecting base 602, and a second electromagnetic block is installed at the connection between the second elastic telescopic tube and the second connecting plate 6041. By controlling the magnitude and direction of the current flowing into the second electromagnetic block, the second connecting plate 6041 can be controlled to move up and down, thereby adjusting the distance between the second connecting plate 6041 and the connecting base 602.

[0090] It should be noted that: in this embodiment, the second elastic telescopic tube can only be axially extended and retracted up and down.

[0091] In this embodiment, a temperature sensor is provided on the outside of the cylinder body 501, which is used to detect the temperature rise rate of the cylinder body 501 itself during the operation of the piston device 6; pressure sensors are provided on both end surfaces of the connecting seat 602, and the pressure sensors are used to detect the air pressure value between the first connecting plate 6031 and the connecting seat 602 and the air pressure value between the second connecting plate 6041 and the connecting seat 602 during the operation of the piston device 6.

[0092] During use, the output shaft of the driving member 401 drives the driven wheel 402 to rotate through the transmission belt 403, and the driven wheel 402 drives the articulated seat 601 to reciprocate up and down inside the cylinder body 501 through the eccentric shaft 404. During this process, the control system synchronously monitors the values ​​of the temperature sensor arranged on the outside of the cylinder body 501 and the pressure sensor arranged on the connecting seat 602, so as to adjust the expansion amount of the first elastic member 6032 and the second elastic member 6042 to avoid the phenomenon of "cylinder pulling" or "cylinder sticking" between the piston device 6 and the cylinder body 501.

[0093] Under normal circumstances, the extrusion between the first elastic member 6032 and the second elastic member 6042 and the inner wall of the cylinder 501 should be in a normal state. As the piston device 6 continues to operate inside the cylinder 501, the value of the pressure sensor set on the connecting seat 602 should also be in a stable state or its value is within a small fluctuation range. The temperature rise rate of the cylinder 501 itself should also be within a stable rising range, that is, the value change of the temperature sensor outside the cylinder 501 is within the temperature rising range.

[0094] When the control system detects that the rising rate of the temperature sensor value exceeds the preset value, but the value of the pressure sensor is in a stable state, it indicates that the amount of extrusion between the first elastic member 6032 and the second elastic member 6042 and the inner wall of the cylinder body 501 exceeds the normal state, that is, the gap between the first elastic member 6032 and the second elastic member 6042 and the cylinder body 501 is too small, which causes the piston device 6 to continue to operate inside the cylinder body 501. The friction between the piston device 6 and the inner wall of the cylinder body 501 is too large, which in turn causes the temperature to rise too quickly.

[0095] When the control system detects that the gap between the first elastic member 6032 and the second elastic member 6042 and the cylinder body 501 is too small, the control system infers the actual gap between the first elastic member 6032 and the second elastic member 6042 and the cylinder body 501 based on the rising rate of the temperature sensor value, and according to the actual gap, a positive current is passed to the electromagnetic blocks on the first connecting plate 6031 and the second connecting plate 6041, so that the electromagnetic blocks on the first connecting plate 6031 and the second connecting plate 6041 generate a repulsive force against the magnetic block on the connecting seat 602. force, thereby causing the first connecting plate 6031 and the second connecting plate 6041 to move away from the connecting seat 602 respectively, that is, the first connecting plate 6031 and the second connecting plate 6041 move away from each other. Affected by the movement of the first connecting plate 6031 and the second connecting plate 6041, the first elastic member 6032 and the second elastic member 6042 are both pulled, thereby causing the expansion amount of the first elastic member 6032 and the second elastic member 6042 to decrease, thereby alleviating the problem of excessive friction between the piston device 6 and the inner wall of the cylinder body 501.

[0096] When the control system detects that the rising rate of the temperature sensor value exceeds the preset value and the value of the pressure sensor is in a non-stable state, it indicates that the amount of extrusion between the first elastic member 6032 and the second elastic member 6042 and the inner wall of the cylinder body 501 is less than normal, that is, the gap between the first elastic member 6032 and the second elastic member 6042 and the cylinder body 501 is too large, which causes the movement of the piston device 6 in the cylinder body 501 to become unstable and prone to lateral deviation or swing. The deviation or swing will cause the first elastic member 6032 and the second elastic member 6042 to be in an unstable contact state with the cylinder wall, thereby causing the value of the pressure sensor to be in a non-stable state.

[0097] When the control system detects that the gap between the first elastic member 6032 and the second elastic member 6042 and the cylinder body 501 is too large, the control system infers the actual gap between the first elastic member 6032 and the second elastic member 6042 and the cylinder body 501 based on the value fluctuation state of the pressure sensor, and according to the actual gap, a reverse current is passed to the electromagnetic blocks on the first connecting plate 6031 and the second connecting plate 6041, so that the electromagnetic blocks on the first connecting plate 6031 and the second connecting plate 6041 generate attraction with the magnetic block on the connecting seat 602. The suction force causes the first connecting plate 6031 and the second connecting plate 6041 to move toward the connecting seat 602 respectively, that is, the first connecting plate 6031 and the second connecting plate 6041 are close to each other. Under the influence of the movement of the first connecting plate 6031 and the second connecting plate 6041, the first elastic member 6032 and the second elastic member 6042 are squeezed, thereby causing the expansion amount of the first elastic member 6032 and the second elastic member 6042 to increase, thereby reducing the irregular swinging phenomenon of the piston device 6 in the cylinder body 501.

[0098] Example 3

[0099] Although the above embodiment improves the sealing between the piston and the cylinder body 501 by controlling the expansion of the first elastic member 6032 and the second elastic member 6042, when the air compressor is running outdoors, excessive impurities will accumulate inside the silencer filter 9, causing the silencer filter 9 to be clogged. The existing technology lacks a mechanism to judge the usage of the silencer filter 9, so that the silencer filter 9 cannot be cleaned in time, which will lead to a reduction in the air compressor intake and exhaust volume and reduce work efficiency. In severe cases, the filter element of the silencer filter 9 may be damaged, allowing air containing impurities to enter the cylinder, wearing the cylinder and the piston, causing high temperature and even burning, and seriously shortening the service life of the equipment. In view of this, technical improvements are made on the basis of Example 2, and the improved technical solution is as follows: Referring to Figures 9 and 10 As shown, a diverter 7 is provided in the middle of the partition plate. The diverter 7 includes a diverter hole 701 , which is provided in the middle of the partition plate for connecting the air inlet chamber 5032 with the air outlet chamber 5033 .

[0100] A blocking block 702 is provided in the middle of the diversion hole 701 and is slidably connected to the partition plate. A through hole 703 is provided on the blocking block 702 .

[0101] A limiting member 704 is provided on the top of the blocking block 702. When the limiting member 704 is in an extended state, the through hole 703 is not connected to the diversion hole 701. When the limiting member 704 is in a contracted state, the through hole 703 and the diversion hole 701 are in a mutually connected state.

[0102] A limiting groove is provided on the cylinder head 5031, the cross section of the blocking block 702 is in the shape of an "I", the top of the blocking block 702 is located in the limiting groove, and the limiting member 704 includes a spring, one end of the spring is connected to the top of the blocking block 702, and the other end of the spring is connected to the limiting groove.

[0103] The elastic force of the limiting member 704 is greater than the elastic force of the elastic steel sheet. When the piston device 6 works normally in the cylinder body 501 , the limiting member 704 is in an extended state. At this time, the through hole 703 is not connected to the diversion hole 701 .

[0104] Reference Figure 8 As shown, a pressing block 605 is provided on the top of the first connecting plate 6031 , and a guide hole 607 is opened on the pressing block 605 .

[0105] A connecting channel 606 is defined on the hinge seat 601 , and the connecting channel 606 is connected to the guide hole 607 via the first telescopic member 6033 .

[0106] A one-way air inlet valve is provided inside the connecting channel 606, and a one-way air outlet valve is provided inside the guide hole 607. When the gap between the piston device 6 and the cylinder body 501 is adjusted, the one-way air inlet valve and the one-way air outlet valve are both in a closed state. The one-way air inlet valve and the one-way air outlet valve will only be opened when the movement amplitude of the first connecting plate 6031 exceeds the normal adjustment requirement.

[0107] A flow sensor is provided inside the air communication pipe 202 , and the flow sensor is used to detect the flow of the compressed gas entering the gas tank 201 .

[0108] During use, when the control system detects that the value of the pressure sensor on the connecting seat 602 is in a stable state, but the value of the flow sensor installed inside the connecting air pipe 202 is less than the set value, it indicates that the filter element inside the silencer filter 9 is blocked, resulting in a decrease in the gas sucked into the cylinder body 501 during the reciprocating operation of the piston device 6 inside the cylinder body 501, which in turn causes the amount of compressed gas to decrease synchronously.

[0109] When the control system detects that the filter element inside the silencer filter 9 is clogged, the control system passes a reverse current to the electromagnetic block on the second connecting plate 6041, so that the electromagnetic block on the second connecting plate 6041 generates an attractive force with the magnetic block on the connecting seat 602, thereby causing the second connecting plate 6041 to move toward the connecting seat 602, forcing the second elastic member 6042 to expand, so as to ensure that gas will not leak from the cylinder 501 during subsequent work.

[0110] At the same time, the control system periodically applies forward and reverse currents to the electromagnetic block on the first connecting plate 6031, causing the first connecting plate 6031 to perform continuous up and down reciprocating motion on the connecting seat 602. When the connecting seat 602 moves upward, since the first connecting plate 6031 is in the process of moving up and down, the top pressure block 605 located at the top of the first connecting plate 6031 will pre-compressively contact the lower portion of the blocking block 702 before the connecting seat 602 reaches its maximum stroke, causing the blocking block 702 to gradually rise, thereby causing the limit member 704 to be in a contracted state, and the through hole 703 to be in a connected state with the diverter hole 701. At this time, the compressed gas entering the air outlet chamber 5033 is diverted at the diverter hole 701, with some of the gas flowing into the interior of the gas tank 201 through the connecting pipe 202, and the other part flowing back to the air inlet chamber 5032 through the through hole 703 and the diverter hole 701. The compressed air entering the air inlet chamber 5032 performs reverse flushing on the filter element in the silencer filter 9, thereby achieving the cleaning function of the filter element.

[0111] In addition, since the first connecting plate 6031 continuously moves up and down, the compressed air entering the air intake chamber 5032 is in a pulse state. This pulsed compressed air performs a pulse cleaning operation on the filter element, which significantly improves the cleaning efficiency.

[0112] It should be noted that: when the diameter of the piston device 6 is normally adjusted, when the top pressure block 605 on the first connecting plate 6031 runs to the maximum stroke, the top pressure block 605 does not produce compressive contact with the bottom of the blocking block 702. Figure 9 As shown by the dotted line in , the maximum stroke is located below the blocking block 702.

[0113] It is worth emphasizing that during the period when the first connecting plate 6031 performs continuous up and down displacement on the connecting seat 602, the current intensity of the electromagnetic block of the first connecting plate 6031 far exceeds the current required for adjusting the gap between the regulating piston device 6 and the cylinder body 501. This design expands the movement amplitude of the first connecting plate 6031, ensuring that the top pressure block 605 can effectively contact the bottom of the blocking block 702 before the connecting seat 602 reaches the limit position, further promoting the efficient operation of the cleaning mechanism.

[0114] Reference Figure 8 As shown, during the period when the first connecting plate 6031 performs continuous up and down displacement on the connecting seat 602, the first telescopic member 6033 is in an uninterrupted extension and contraction operation. When the first telescopic member 6033 is extended, a negative pressure is generated inside it, and the negative pressure opens the one-way air intake valve inside the connecting channel 606, and external gas can enter the first telescopic member 6033 through the one-way air intake valve; when the first telescopic member 6033 is contracted, due to the reduction of the internal space of the first telescopic member 6033, the gas entering the first telescopic member 6033 is discharged into the interior of the cylinder body 501 through the guide hole 607, so as to increase the gas volume of the cylinder body 501, and avoid the gas volume of the cylinder body 501 being too small, resulting in too little compressed gas entering the air intake chamber 5032, resulting in the filter element being unable to be adequately cleaned.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
