[0001] The invention belongs to the technical field of air compressors, and in particular relates to an air compressor with an air filter element quick replacement structure. Background Art

[0002] Air compressors are widely used in a variety of industrial applications to provide compressed air to support production and manufacturing processes. In these applications, maintaining the quality of compressed air is critical, and air filters are an important part of ensuring air quality.

[0003] Current air compressors usually use fixed air filters, and replacing the filter element requires disassembling and reassembling the filter element frame. This process may require professional technicians and is time-consuming. In addition, due to the close connection between the filter element and other parts of the compressor, replacing the filter element may cause the machine to be downtime extended, causing unnecessary interruptions to production. Therefore, an air compressor with an air filter element quick replacement structure is designed to change the above technical defects. Summary of the invention

[0004] (1) Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an air compressor with an air filter element quick replacement structure. The air compressor is intended to solve the technical problem that under the prior art, replacement of the filter element requires disassembly and reassembly of the filter element frame, a process that may require professional technicians and is relatively time-consuming, and replacement of the filter element may cause prolonged machine downtime.

[0006] (2) Technical solution

[0007] In order to solve the above technical problems, the present invention provides an air compressor with an air filter element quick replacement structure, the air compressor comprising an air compressor body, an arc-shaped fixing block is bolted to one side of the air compressor body, a filter tank is sleeved inside the arc-shaped fixing block, an air inlet pipe is assembled at one end of the filter tank, an air outlet pipe is arranged at the other end of the top of the filter tank, the air outlet pipe is connected to the air compressor body, an annular fixing ring is arranged at the other end of the filter tank, a detachable circular mounting seat is arranged inside the annular fixing ring, and the annular fixing ring and the circular mounting seat are connected by a first connecting mechanism;

[0008] A filter body is arranged inside the filter tank, and a filter bottom is assembled on one end of the filter body close to the circular mounting seat. The filter bottom is connected to the circular mounting seat via a second connecting mechanism.

[0009] When the air compressor using the technical solution needs to disassemble the filter body, the circular pull block is first pulled in the direction away from the circular pull block. The movement of the circular pull block passes through the third transmission column, so that the transverse limit column can move inside the circular mounting seat, so that the transverse limit column can move out of the transverse limit groove, so that the circular mounting seat can be separated from the inside of the annular fixing ring. In this process, the movement of the transverse limit column causes the second spring to be contracted under force;

[0010] Then, the filter body can be moved out of the filter tank through the two U-shaped handles, and then the handwheel is rotated. The rotation of the handwheel enables the circular rotating part to rotate inside the circular mounting seat through the horizontal rotating rod. The rotation of the circular rotating part enables the sliding rod to slide inside the circular mounting seat through the first transmission column and the second transmission column, thereby enabling the L-shaped clamping column to move in the direction away from the circular mounting seat, so that the L-shaped clamping column can move out of the rectangular limiting groove inside the bottom of the filter, so that the filter body can be disassembled. In this process, the movement of the L-shaped clamping column causes the first spring to contract under force.

[0011] Preferably, the second connecting mechanism includes a circular rotating member, which is located inside the circular mounting seat and is rotatably connected to the circular mounting seat through a bearing, a plurality of first transmission columns are fixed to the outside of the circular rotating member, the outside of the first transmission column is rotatably connected to the second transmission column through a pin shaft, the end of the second transmission column away from the circular rotating member is rotatably connected to a sliding rod through a pin shaft, the sliding rod is located inside the circular mounting seat and is slidably connected to the circular mounting seat, and an L-shaped clamping column is fixed to the end of the circular mounting seat away from the circular rotating member.

[0012] Furthermore, a circular fixing block is fixed on the outer side of the circular mounting seat, and a first spring is arranged between the circular fixing block and the circular mounting seat and on the outer side of the sliding rod. Through the setting of the first spring, when the sliding rod slides inside the circular mounting seat, the first spring is deformed under force so that the L-shaped clamping column can limit the bottom of the filter.

[0013] Furthermore, a circular through hole adapted to the sliding rod is provided inside the circular mounting seat, and the circular mounting seat and the sliding rod are slidably connected via the circular through hole. The circular through hole enables the circular mounting seat to slide inside the sliding rod;

[0014] A rectangular limiting groove adapted to the L-shaped clamping column is provided inside the bottom of the filter, so that the L-shaped clamping column can enter the rectangular limiting groove inside the bottom of the filter.

[0015] Furthermore, a transverse rotating rod is fixed to one end of the circular rotating member away from the filter body, and a handwheel is fixed to one end of the transverse rotating rod. The transverse rotating rod passes through the interior of the circular mounting seat and is rotatably connected to the circular mounting seat through a bearing, so that the transverse rotating rod can pass through the interior of the circular mounting seat and can rotate inside the circular mounting seat. Through the setting of the handwheel, the circular rotating member can better rotate inside the circular mounting seat.

[0016] Furthermore, the second connecting mechanism includes an annular pull block, both sides of which are rotatably connected to the third transmission column, and the end of the third transmission column close to the circular mounting seat is rotatably connected to a transverse limit column, the transverse limit column is located inside the circular mounting seat and is slidably connected to the circular mounting seat, and vertical limit plates are also fixed on both sides of the circular mounting seat, and a second spring is arranged between the vertical limit plate and the transverse limit column.

[0017] Furthermore, dovetail sliders are fixed to the top and bottom of the transverse limit column, and a dovetail slot adapted to the dovetail slider is provided inside the circular mounting seat. The transverse limit column and the circular mounting seat are slidably connected through the cooperation of the dovetail slider and the dovetail slot. The dovetail slider and the dovetail slot are set to limit the movement trajectory of the transverse limit column.

[0018] Furthermore, a first inclined surface is provided at one end of the transverse limiting column close to the annular fixing ring, a second inclined surface is provided at one end of the annular fixing ring close to the transverse limiting column, and a transverse limiting groove is provided inside the annular fixing ring to match the clearance of the transverse limiting column. By setting the first inclined surface and the second inclined surface, when the circular mounting seat moves toward the annular fixing ring, the setting of the first inclined surface and the second inclined surface enables the transverse limiting column to move toward the direction of the vertical limiting plate, so that the circular mounting seat can enter the interior of the circular mounting seat. By setting the transverse limiting groove, the transverse limiting column can enter the interior of the annular fixing ring, thereby limiting the movement of the circular mounting seat inside the annular fixing ring.

[0019] Furthermore, the annular pull block and the third transmission column, as well as the third transmission column and the transverse limit column, are rotationally connected via a pin shaft, so that the annular pull block and the third transmission column, as well as the third transmission column and the transverse limit column can be rotationally connected better.

[0020] Furthermore, U-shaped handles are fixed on both sides of the circular mounting seat away from the filter body, so that the circular mounting seat can be better moved out of the annular fixing ring.

DETAILED DESCRIPTION

[0033] This specific embodiment is an air compressor with an air filter element quick replacement structure, and its structural schematic diagram is as follows Figure 1-Figure 8As shown, the air compressor includes an air compressor body 1, an arc-shaped fixing block 5 is bolted to one side of the air compressor body 1, a filter tank 2 is sleeved inside the arc-shaped fixing block 5, an air inlet pipe 4 is assembled at one end of the filter tank 2, an air outlet pipe 3 is arranged at the other end of the top of the filter tank 2, and the air outlet pipe 3 is connected to the air compressor body 1, an annular fixing ring 9 is arranged at the other end of the filter tank 2, a detachable circular mounting seat 8 is arranged inside the annular fixing ring 9, and the annular fixing ring 9 and the circular mounting seat 8 are connected by a first connecting mechanism;

[0034] A filter body 6 is disposed inside the filter tank 2 , and a filter bottom 7 is mounted on one end of the filter body 6 close to the circular mounting seat 8 . The filter bottom 7 is connected to the circular mounting seat 8 via a second connecting mechanism.

[0035] Among them, the second connecting mechanism includes a circular rotating part 13, which is located inside the circular mounting seat 8 and is rotatably connected to the circular mounting seat 8 through a bearing. A plurality of first transmission columns 16 are fixed to the outside of the circular rotating part 13. The outside of the first transmission column 16 is rotatably connected to the second transmission column 17 through a pin shaft. The end of the second transmission column 17 away from the circular rotating part 13 is rotatably connected to a sliding rod 18 through a pin shaft. The sliding rod 18 is located inside the circular mounting seat 8 and is slidably connected to the circular mounting seat 8. An L-shaped clamping column 11 is fixed to the end of the circular mounting seat 8 away from the circular rotating part 13.

[0036] A circular fixing block 19 is fixed to the outer side of the circular mounting seat 8, and a first spring 20 is arranged between the circular fixing block 19 and the circular mounting seat 8 and on the outer side of the sliding rod 18. By setting the first spring 20, when the sliding rod 18 slides inside the circular mounting seat 8, the first spring 20 is deformed by force, so that the L-shaped clamping column 11 can restrict the filter bottom 7;

[0037] A circular through hole adapted to the sliding rod 18 is provided inside the circular mounting seat 8, and the circular mounting seat 8 and the sliding rod 18 are slidably connected via the circular through hole. The circular through hole enables the circular mounting seat 8 to slide inside the sliding rod 18;

[0038] A rectangular limiting groove adapted to the L-shaped clamping column 11 is provided inside the filter bottom 7, so that the L-shaped clamping column 11 can enter the rectangular limiting groove inside the filter bottom 7, thereby limiting the movement of the filter bottom 7 at one end of the circular mounting seat 8;

[0039] A transverse rotating rod 14 is fixed to one end of the circular rotating member 13 away from the filter body 6, and a hand wheel 15 is fixed to one end of the transverse rotating rod 14. The transverse rotating rod 14 passes through the interior of the circular mounting seat 8 and is rotatably connected to the circular mounting seat 8 through a bearing, so that the transverse rotating rod 14 can pass through the interior of the circular mounting seat 8 and can rotate inside the circular mounting seat 8. The hand wheel 15 is provided so that the circular rotating member 13 can better rotate inside the circular mounting seat 8.

[0040] In addition, the second connecting mechanism includes an annular pull block 21, and the third transmission column 22 is rotatably connected on both sides of the annular pull block 21. The third transmission column 22 is rotatably connected to the end of the circular mounting seat 8, and the transverse limit column 12 is located inside the circular mounting seat 8 and is slidably connected to the circular mounting seat 8. Vertical limit plates 23 are also fixed on both sides of the circular mounting seat 8, and a second spring 24 is arranged between the vertical limit plate 23 and the transverse limit column 12.

[0041] The top and bottom of the transverse limit column 12 are fixed with dovetail sliders, and the inside of the circular mounting seat 8 is provided with a dovetail slot adapted to the dovetail slider. The transverse limit column 12 and the circular mounting seat 8 are slidably connected through the cooperation of the dovetail slider and the dovetail slot. The setting of the dovetail slider and the dovetail slot can limit the movement track of the transverse limit column 12.

[0042] A first inclined surface is provided at one end of the transverse limiting column 12 close to the annular fixing ring 9, a second inclined surface is provided at one end of the annular fixing ring 9 close to the transverse limiting column 12, and a transverse limiting groove is provided inside the annular fixing ring 9 to be gap-matched with the transverse limiting column 12. By setting the first inclined surface and the second inclined surface, when the circular mounting seat 8 moves toward the annular fixing ring 9, the setting of the first inclined surface and the second inclined surface enables the transverse limiting column 12 to move toward the direction of the vertical limiting plate 23, so that the circular mounting seat 8 can enter the interior of the circular mounting seat 8. By setting the transverse limiting groove, the transverse limiting column 12 can enter the interior of the annular fixing ring 9, thereby limiting the movement of the circular mounting seat 8 inside the annular fixing ring 9;

[0043] The annular pull block 21 and the third transmission column 22 as well as the third transmission column 22 and the transverse limiting column 12 are all rotationally connected via a pin shaft, thereby enabling the annular pull block 21 and the third transmission column 22 as well as the third transmission column 22 and the transverse limiting column 12 to be better rotationally connected;

[0044] U-shaped handles 10 are fixed on both sides of the circular mounting seat 8 at one end away from the filter body 6 , so that the circular mounting seat 8 can be better moved out of the annular fixing ring 9 .

[0045] Working principle: When the air compressor using the present technical solution needs to disassemble the filter body 6, the circular pull block 21 is first pulled in a direction away from the circular pull block 21. The movement of the circular pull block 21 passes through the third transmission column 22, so that the transverse limit column 12 can move inside the circular mounting seat 8, so that the transverse limit column 12 can move out of the transverse limit groove, so that the circular mounting seat 8 can be separated from the inside of the annular fixing ring 9. In this process, the movement of the transverse limit column 12 causes the second spring 24 to be contracted under force;

[0046] Then, the filter body 6 can be moved out of the interior of the filter tank 2 through the two U-shaped handles 10, and then the handwheel 15 is rotated. The rotation of the handwheel 15 enables the circular rotating member 13 to rotate inside the circular mounting seat 8 through the lateral rotating rod 14. The rotation of the circular rotating member 13 enables the sliding rod 18 to slide inside the circular mounting seat 8 through the first transmission column 16 and the second transmission column 17, thereby enabling the L-shaped clamping column 11 to move in a direction away from the circular mounting seat 8, so that the L-shaped clamping column 11 can move out of the rectangular limiting groove inside the filter bottom 7, so that the filter body 6 can be disassembled. During this process, the movement of the L-shaped clamping column 11 causes the first spring 20 to be forced to contract. Therefore, through the setting of the first disassembly mechanism and the second disassembly mechanism, the operator can quickly and easily disassemble and replace the filter body 6 without the need for professional technical support, thereby reducing the downtime caused by replacing the filter body 6.

[0047] All technical features in this embodiment can be freely combined according to actual needs.

[0048] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
