[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0029] like Figures 1 to 3 As shown, an embodiment of the present invention provides an air compressor inlet filter installation structure, which includes a connecting ring 2, a mounting ring 6, and a sleeve ring 8. One end of the connecting ring 2 is detachably connected to one end of the motor assembly 1 of the air compressor, and a card slot 3 and a limit slot 20 are provided on the end of the connecting ring 2 away from the motor assembly. The extension directions of the card slot 2 and the limit slot 20 are parallel to the axis of the connecting ring; a through hole 21 opposite to the card slot and a through hole 22 opposite to the limit slot are provided on the sleeve ring 8, and a first filter screen 9 is provided in the sleeve ring; the sleeve ring and the mounting ring are both coaxially arranged with the connecting ring, and the sleeve ring 8 is arranged at Between the connecting ring and the mounting ring; a limiting rod 7 is vertically provided on the side of the mounting ring 6 for contacting the sleeve, and the limiting rod 7 passes through the through hole and cooperates with the limiting groove; a pressure plate 13 parallel to the limiting rod 7 is provided on the mounting ring, and a buckle 14 is provided on the end of the pressure plate 13 close to the connecting ring, and the buckle 14 passes through the through hole and is engaged with the slot; the end of the pressure plate 13 away from the connecting ring passes through the mounting hole 24 of the mounting ring, and the pressure plate 13 has a first position for cooperating with the buckle and a second position for disengaging the buckle from the slot.

[0030] The air compressor inlet filter installation structure provided by the embodiment of the present invention is that when the filter needs to be cleaned or replaced, it is only necessary to place the pressure plate 13 in the second position so that the buckle 14 of the pressure plate 13 is disengaged from the card slot 3, and then the mounting ring can be moved in the direction away from the connecting ring, so that the limiting plug 7 is pulled out from the limiting groove, and the collar and the mounting ring are removed from the connecting ring together, and then the first filter 9 in the collar can be cleaned or replaced, so that the operator can easily clean or replace the first filter, thereby better avoiding the service life of the air compressor being reduced; at the same time, after the cleaning or replacement operation of the first filter 9 is completed, it is only necessary to place the collar between the connecting ring and the mounting ring, so that the limiting plug passes through the through hole and cooperates with the limiting groove, and at the same time, the buckle of the pressure plate passes through the through hole and engages with the card slot, so that the first filter can be installed between the motor assembly, thereby making the installation of the first filter more convenient and quick.

[0031] Furthermore, the air compressor inlet filter installation structure provided in an embodiment of the present invention also includes a swivel 10 coaxial with the collar. An annular groove is provided within the collar on a side away from the connecting ring. The swivel 10 is mounted within the annular groove. A second filter 11 is also provided within the swivel. This solution provides improved filtering through the first and second filters, facilitating use in various environments and preventing excessive dust from entering the motor assembly and potentially damaging the air compressor when operating in dusty environments.

[0032] Specifically, a control lever 12 is provided on the side of the swivel away from the connecting ring. The extension direction of the control lever 12 is parallel to the axis of the swivel. The control lever can be used to rotate the swivel, so that the second filter mesh approaches the first filter mesh and overlaps with the first filter mesh, increasing the filtration density and achieving a better filtration effect. It is understood that the swivel is constrained between the bottom of the annular groove and the mounting ring; the swivel can transition with the inner wall of the annular groove, and the swivel can be rotated within the annular groove by operating the control lever.

[0033] In order to more conveniently realize the rotation of the swivel 10 , there are two control rods 12 , which are arranged opposite to each other.

[0034] Specifically, there are four limiting rods 7, and each limiting rod 7 is evenly distributed on the circumference of the mounting ring; there are four through holes 22 and four limiting grooves 20, and each limiting rod corresponds to each through hole and each limiting groove one by one, so that the connection between the mounting ring, the sleeve ring and the connecting ring is more firm and reliable.

[0035] In order to facilitate the insertion of the limiting rod 7 into the through hole to achieve cooperation with the limiting groove 20 , the end of the limiting rod away from the mounting ring is a tapered structure.

[0036] Specifically, one end of the motor assembly 1 is provided with an external thread 19, and one end of the connecting ring is provided with an internal thread matching the external thread, thereby conveniently achieving a detachable connection between the motor assembly and the connecting ring.

[0037] Furthermore, a connecting seat 4 is vertically disposed on the lower outer wall of the connecting ring, and an assembly seat 5 is disposed on the lower outer wall of the mounting ring. The connecting seat 4 is provided with a rotating shaft 23 perpendicular to the axis of the connecting ring, and the assembly seat is provided with an axial hole that rotatably cooperates with the rotating shaft. Thus, the connecting seat and the assembly seat can support and limit the mounting ring and the collar, thereby ensuring a relatively secure and reliable connection between the connecting ring, the collar, and the mounting ring. It is understood that when the first filter screen needs to be cleaned or replaced, the buckle can be disengaged from the slot and the mounting ring can be rotated around the rotating shaft to disengage the limiting rod from the limiting slot. The collar will then rotate along with the mounting ring around the rotating shaft. The limiting rod can then be disengaged from the through hole and the collar can be removed from the mounting ring. The first filter screen can then be cleaned or replaced without removing the mounting ring from the connecting ring, thereby saving time during installation of the mounting ring and the connecting ring.

[0038] In another embodiment provided by the present invention, there can be two snap-in slots, which are relatively arranged at the upper and lower portions of the connecting ring or relatively arranged at the left and right sides of the connecting ring. The mounting ring is provided with two pressure plates, and the buckles of the two pressure plates respectively engage with the two snap-in slots in a one-to-one correspondence. With this solution, the two snap-in slots and the two buckles can provide a more secure and reliable connection between the connecting ring and the mounting ring and the collar. It is also preferred that there are three snap-in slots and three pressure plates, with the three snap-in slots evenly distributed around the circumference of the connecting ring, and the buckles of the three pressure plates respectively engage with the three snap-in slots in a one-to-one correspondence.

[0039] Further, if Figure 3 As shown, a spring seat 17 is provided on the lower inner wall of the mounting hole 24 , a spring 16 is provided between the middle position of the pressure plate 13 and the spring seat 17 ; and limit blocks 15 are provided on both sides of the middle position of the pressure plate. When the buckle is disassembled, the spring is compressed, and the buckle 14 is disengaged from the slot, that is, the pressure plate is in the second position. When the buckle is disengaged from the slot and the through-hole, the pressure plate will return to its original position under the action of the restoring force of the spring; when installing, the buckle passes through the through-hole into the slot and is locked in the slot. At this time, the spring can prevent the buckle from being disengaged from the slot, and the pressure plate is in the first position; at the same time, the limit block can prevent the pressure plate from being disengaged from the installation hole; it can be understood that the buckle can be a right-angled triangle structure, the side surface of the buckle close to the connecting ring is an inclined surface, and the side surface of the buckle away from the connecting ring is a vertical surface, and the slot has a limiting surface that blocks the vertical surface. In this way, the buckle can be prevented from being disengaged from the slot by blocking the vertical surface with the limiting surface.

[0040] Specifically, a mounting seat 18 is provided on the lower outer wall of the motor assembly 1 , and a fixing hole is provided on the mounting seat, so that the motor assembly can be installed on the floor by utilizing the fixing holes on the mounting seat 18 .

[0041] The above are only preferred embodiments of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in this field can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
