Description

Technical Field

[0001] The utility model belongs to the technical field of air compressors, and in particular relates to an air compressor filter device which is easy to disassemble. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. They can be divided into several types according to their working principle, lubrication method, performance, etc.

[0003] For example, a Chinese patent with publication number CN218358037U discloses an air compressor with a filter device, including a body, one side of the body is evenly provided with a plurality of fins from top to bottom, a socket is provided on the top of the body near the side where the fins are provided, a filter assembly is provided on the inner side of the socket, a mounting plate is provided on the side of the filter assembly facing the inner side of the body, a plurality of exhaust fans are installed on the mounting plate, and a movable base is installed on the bottom end of the filter assembly. The utility model solves the problem that the existing filter device is inconvenient to install and disassemble, which affects the cleaning of the filter device, and the air filter device is not provided at the air inlet of the existing air compressor. By improving and optimizing the structure of the air compressor, a filter device is installed at the air inlet of the air compressor, which facilitates the rapid filtering of the air entering the air compressor, and the filter device of this structure is convenient and quick to disassemble and assemble, which is convenient for disassembling and cleaning the air compressor, and effectively improves the flexibility of use of the air compressor.

[0004] The patent has some disadvantages when in use, such as: the device in the patent realizes the installation and removal of the filter assembly by pulling the filter assembly upward, which has certain defects: first, the multiple exhaust fans in the device are fixed to the filter assembly through the mounting plate. When the filter assembly is pulled upward, due to the high height of the air compressor itself and the height of the filter assembly itself, as the filter assembly continues to move upward, due to the certain height of the operator, it is no longer convenient for the operator to continue to pull the filter assembly upward, and due to the change in the force angle, the operator needs to exert more force to move the filter assembly upward as the lifting height increases; in addition, the device sets a mounting plate on one side of the filter plate and sets multiple exhaust fans on the mounting plate. Since the mounting plate blocks the air, the air can only pass through the air outlet where the exhaust fan is located and be sucked into the air compressor. This process greatly increases the air compressor's air suction efficiency and increases the working loss. In view of this, we propose an air compressor filter device that is easy to disassemble.

[0055] A bracket 27, the bracket 27 is arranged on a side of the lifting column 14 and away from the mounting frame 6, and a plurality of groups of fans 28 evenly distributed are installed in the bracket 27;

[0056] In this embodiment, the limiting component includes:

[0057] Slide groove 8, which is provided on the upper surface of the lower cross bar of the installation frame 6, and a wedge block 9 is slidably connected in the slide groove 8, and a spring 10 is symmetrically fixed at the bottom of the wedge block 9, and a through groove 11 connected to the slide groove 8 is provided on the right side wall of the installation frame 6 and close to the slide groove 8, and a toggle block 12 fixed to the wedge block 9 is slidably connected in the through groove 11, and the toggle block 12 is in a J-shaped structure, and a baffle 13 is symmetrically fixed at the left side of the inner side of the installation frame 6, and the cross section of the wedge block 9 is in a straight trapezoidal shape, and the slope of the upper surface of the wedge block 9 faces the right side, and the air inlet net 7 is located between the wedge block 9 and the two baffles 13;

[0058] In this embodiment, the driving component includes:

[0059] The mounting plate 17 is fixedly mounted on the outer wall of the lower part of the body 1, and a motor 18 is fixed to the lower surface of the mounting plate 17. The output shaft end of the motor 18 is coaxially connected with a connecting shaft 19, and two clamps 20 fixed to the lower surface of the body 1 are rotatably connected to the connecting shaft 19. The end of the clamp 20 away from the motor 18 is coaxially connected with a bevel gear 1 21, and the circumferential side of the bevel gear 1 21 is meshingly connected with a bevel gear 22. The bevel gear 22 is coaxially connected with a connecting rod 23 fixed to the bottom end of the threaded rod 15. A protective cover 24 fixed to the lower surface of the body 1 is provided on the outer sides of the bevel gears 1 21 and 22, and the bottom end of the connecting rod 23 is rotatably matched with the inner bottom surface of the protective cover 24.

[0060] Among them, the working principle of this device is as follows:

[0061] When the air intake net 7 is disassembled, the drive assembly is started, and the motor 18 in the drive assembly works. The output shaft of the motor 18 rotates and drives the connecting shaft 19 to rotate. The connecting shaft 19 drives the bevel gear 1 21 to rotate, and the bevel gear 1 21 drives the bevel gear 2 22 to rotate. The bevel gear 22 drives the connecting rod 23 to rotate, and the connecting rod 23 drives the threaded rod 15 to rotate. Under the action of the thread force, the threaded block 16 moves upward along the inner cavity of the lifting column 14, and drives the installation frame 6 to move upward. The installation frame 6 gradually extends upward from the inlet and outlet 2, and exposes the air intake net 7 to the outside. At this time, the operator presses the toggle block 12 downward, and the toggle block 12 drives the wedge block 9 to slide downward and squeezes the spring 10. When the wedge block 9 is completely collected in the slide groove 8, the wedge block 9 no longer constrains the air intake net 7. Then the operator pulls the air intake net 7 outward, and the air intake net 7 can be taken out from the mouth-shaped frame of the installation frame 6, and the air intake net 7 can be cleaned or replaced.

[0062] When installing the air intake net 7, the operator only needs to first extend one side of the upper cross bar of the air intake net 7 into the U-shaped frame of the installation frame 6, and then squeeze the lower part of the air intake net 7 inward, and the lower part of the air intake net 7 squeezes the wedge block 9. Due to the presence of the slope of the wedge block 9, the air intake net 7 can be squeezed into the slide groove 8 by the air intake net 7. As the air intake net 7 completely falls into the U-shaped frame of the installation frame 6, the wedge block 9 is acted upon by the elastic force of the two springs 10, and then the motor 18 in the drive assembly is started in reverse, so that the installation frame 6 falls back into the inner cavity of the machine body 1.

[0063] By setting a lifting column 14, a threaded rod 15 and a threaded block 16, and driving the threaded rod 15 to rotate through a driving component, the threaded block 16 can drive the installation frame 6 to move upward or downward along the lifting column 14 under the action of the thread force, so that the air intake net 7 is exposed to the outside or retracted into the inner cavity of the body 1, thereby solving the problem that the air intake net 7 needs to be pulled upward by manpower in the traditional device, which is laborious and highly inconvenient; by setting a limit component, the wedge block 9 and two baffles 13 are used to form an effective clamping constraint on the air intake net 7 in the square frame of the installation frame 6, ensuring that the air intake net 7 can be stably installed in the installation frame 6, and it is also more convenient to disassemble and install.

[0064] Embodiment 2:

[0065] This embodiment provides an air compressor filter device that is easy to disassemble. In addition to the technical solutions of the above embodiments, it also has the following technical features: handles are symmetrically fixed to the edge of one side of the air inlet net 7 facing the right side.

[0066] The provision of a handle makes it easy for an operator to pull the air inlet net 7 out of the square-shaped frame of the installation frame 6 .

[0069] By providing two stabilizing plates 25 , the installation frame 6 can run more smoothly when moving up and down.

In addition to the technical solutions of the above embodiments, it also has the following technical features: two symmetrically arranged limit guide rails 26 are fixed to the inner cavity of the body 1 and located at the upper and lower ends of the bracket 27.

[0072] By providing two limiting guide rails 26 , the bracket 27 can be stably fixed in the inner cavity of the body 1 , thereby preventing the bracket 27 from shaking.

In addition to the technical solutions of the above embodiments, it also has the following technical features: the bracket 27 has a grid structure, and a handle is fixed on the side of the bracket 27 facing the placement port 4.

[0075] Among them, by arranging the bracket 27 into a grid shape, the wind passing rate of multiple fans 28 is increased during operation, thereby improving the working efficiency of the device and improving the shortcoming of the traditional device in which the air intake volume is small when only exhausting air through the air duct holes of the exhaust fan.
