Description

Technical Field

[0001] This utility model relates to the field of air compressors, and more particularly to an air compressor. Background Technology

[0002] Air compressors, as devices that convert mechanical energy into gas pressure energy, are widely used in many fields such as industrial production, construction, and pneumatic tool operation. Their working principle involves drawing in outside air, compressing it, and then outputting high-pressure gas for use by various equipment.

[0003] However, outside air usually contains a certain amount of moisture and impurities. When this moisture enters the air compressor, it can adversely affect the normal operation of the equipment. For example, when moisture mixes with the lubricating oil inside the air compressor, it reduces the lubricating performance of the oil, accelerates the wear of moving parts such as pistons and cylinders, and shortens the service life of the equipment. At the same time, compressed air containing moisture may also damage the air-using equipment during subsequent use, affecting the working stability and reliability of the pneumatic system.

[0004] To address the aforementioned issues, existing technologies typically incorporate a dehumidifier at the air intake of the air compressor to remove moisture from the air. However, current dehumidifiers are mostly single-function devices with limited dehumidification capabilities. Furthermore, when the dehumidifying material fails, the entire unit needs to be disassembled and replaced, resulting in cumbersome operation and high maintenance costs. In addition, existing dehumidifiers lack effective monitoring of the dehumidifying material's failure status, making it difficult to accurately determine when to replace it. This can lead to poor dehumidification performance or delayed replacement, affecting the normal operation of the air compressor.

[0005] Therefore, those skilled in the art are dedicated to developing an air compressor. Utility Model Content

[0006] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is to improve the dehumidification effect at the air inlet of the air compressor so as to avoid damage to the air compressor and subsequent air-using equipment caused by moisture in the air; simplify the replacement operation of dehumidification components, reduce maintenance difficulty and cost; and realize effective monitoring of the failure state of dehumidification components so as to promptly indicate the time of replacement and ensure the continuous and stable operation of the dehumidification function.

[0007] To achieve the above objectives, this utility model provides an air compressor, including an air compressor body. An air inlet pipe is connected to the air inlet end of the air compressor body. A dehumidification box is fixedly connected to the upper end of the air inlet pipe. A flip plate is provided inside the dehumidification box. Dehumidification cylinders are provided on both the upper and lower sides of the flip plate. Air outlets are provided on the opposite sides of the two dehumidification cylinders. An air intake pipe is fixedly connected to the upper end of the dehumidification box. Two movable plates are provided inside the dehumidification box. A connecting pipe is connected through both movable plates. Corrugated pipes are connected to the opposite sides of the two connecting pipes. The upper corrugated pipe is connected to the air intake pipe, and the lower corrugated pipe is connected to the air inlet pipe.

[0008] In a preferred embodiment of this utility model, the dehumidifier cylinder includes a mesh cylinder filled with activated carbon.

[0009] In another preferred embodiment of this utility model, sealing rings are fixedly connected to the opposite sides of the two connecting pipes.

[0010] In another preferred embodiment of the present invention, weighing components are provided on both the upper and lower sides of the flip plate. The weighing components include two L-shaped blocks fixedly connected to the flip plate. A pressure rod is slidably connected through each of the two L-shaped blocks. Two pressure sensors that cooperate with the pressure rods are fixedly connected to the flip plate. Limiting rings are fixedly connected to each of the two pressure rods.

[0011] In another preferred embodiment of the present invention, each of the pressure rods is connected to the corresponding dehumidifier cylinder by a connecting assembly. The connecting assembly includes a fixing block fixedly connected to the pressure rod, and a fixing bolt is threaded through the fixing block. The left and right sides of the dehumidifier cylinder are provided with threaded holes that cooperate with the fixing bolts.

[0012] In another preferred embodiment of the present invention, a sliding door is rotatably connected to the front side of the dehumidification box, and rotating rods are rotatably connected to the inner walls of both the front and rear sides of the dehumidification box. The adjacent sides of the two rotating rods are fixedly connected to the flip plate, and the rotating rod located on the rear side extends to the outside and is fixedly connected to a second knob.

[0013] In another preferred embodiment of the present invention, the inner top and inner bottom of the dehumidification box are rotatably connected to a bidirectional lead screw, the bidirectional lead screw passes through two movable plates, the two movable plates are threadedly connected to the bidirectional lead screw, the two movable plates are slidably connected to the right inner wall of the dehumidification box, and the upper end of the bidirectional lead screw extends to the outside and is fixedly connected to a first knob.

[0014] In another preferred embodiment of the present invention, a metal filter screen is provided inside the air intake pipe.

[0015] In another preferred embodiment of this utility model, a sealing gasket is provided at the contact area between the sliding door and the dehumidification box.

The pressure sensor, the controller, and the indicator light are connected in sequence by wires.

[0017] The device provided by this utility model has the following technical effects:

[0018] 1. This device, by setting a flip plate and two dehumidification cylinders inside the dehumidification box, combined with a specific airflow path design, allows air to pass through the two dehumidification cylinders in sequence for dehumidification treatment, which is equivalent to achieving double dehumidification, greatly improving the dehumidification effect, and can more effectively remove moisture from the air, reducing the damage of moisture to the air compressor and subsequent air-using equipment.

[0019] 2. This device utilizes the flipping function of the flipping plate and the structure of a separately detachable dehumidifying cylinder. When the dehumidifying material in the upper dehumidifying cylinder fails, you only need to switch the dehumidifying cylinder by flipping the plate and use the connecting components to disassemble and replace the failed dehumidifying cylinder separately. There is no need to disassemble the entire dehumidifying device, which simplifies the replacement operation, reduces maintenance difficulty and cost, and allows the dehumidifying cylinder that was previously located at the bottom to be rotated to the top for use, so that the new dehumidifying cylinder will not fail too quickly.

[0020] 3. This device uses a weighing component, controller, and indicator lights to monitor the weight change of the dehumidification cylinder located above by a pressure sensor, thereby determining the failure status of the dehumidification material. When the replacement threshold is reached, the indicator light will promptly alert the user, thus achieving effective monitoring of the failure status of the dehumidification components. This allows users to accurately grasp the replacement timing and ensure the continuous and stable operation of the dehumidification function.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation.

[0029] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.

[0030] like Figures 1-4As shown, an air compressor includes an air compressor body 1. An air inlet pipe 3 is connected to the air inlet end of the air compressor body 1. A dehumidification box 2 is fixedly connected to the upper end of the air inlet pipe 3. A flip plate 12 is provided inside the dehumidification box 2. Dehumidification cylinders 10 are provided on both the upper and lower sides of the flip plate 12. Each dehumidification cylinder 10 includes a mesh cylinder, which is composed of two circular plates and a cylindrical mesh. Circular holes are provided on the circular plates away from the flip plate 12, and grids are provided inside the holes to prevent activated carbon from falling out during subsequent flipping. The mesh cylinder is filled with activated carbon, which has a strong adsorption capacity and can adsorb moisture from the air. Air outlets are provided on the opposite sides of the two dehumidification cylinders 10. The upper end of the dehumidification box 2 is fixedly connected to an air intake pipe 4. The air intake pipe 4 is equipped with a metal filter screen, which can perform preliminary filtration of the incoming outside air, blocking large particles such as dust and impurities in the air from entering the device and protecting the subsequent components. The dehumidification box 2 is equipped with two movable plates 9, and each movable plate 9 is connected to a connecting pipe 11. The opposite sides of the two connecting pipes 11 are connected to a corrugated pipe 7. The upper corrugated pipe 7 is connected to the air intake pipe 4, and the lower corrugated pipe 7 is connected to the air inlet pipe 3. The opposite sides of the two connecting pipes 11 are fixedly connected to a sealing ring. The sealing ring can enhance the sealing between the connecting pipe 11 and the dehumidification cylinder 10, prevent gas leakage at the connection, and ensure that all gas can pass through the dehumidification cylinder 10 for dehumidification treatment.

[0031] The flip plate 12 is equipped with weighing components on both the upper and lower sides. The weighing components include two L-shaped blocks 13 fixedly connected to the flip plate 12. Each L-shaped block 13 is slidably connected with a pressure rod 16. The flip plate 12 is fixedly connected with two pressure sensors 17 that cooperate with the pressure rods 16. An indicator light is fixedly connected to the upper end of the dehumidification box 2. A controller is provided inside the dehumidification box 2. The pressure sensors 17, the controller, and the indicator light are electrically connected in sequence through wires. Each pressure rod 16 is fixedly connected with a limit ring 18. The limit ring 18 can prevent the pressure rod 17 from falling off the L-shaped block 13 after rotating to the lower position. Each pressure rod 16 is connected to the corresponding dehumidification cylinder 10 through a connecting component. The connecting component includes a fixing block 14 fixedly connected to the pressure rod 16. A fixing bolt 15 is threadedly connected to the fixing block 14. The left and right sides of the dehumidification cylinder 10 are provided with threaded holes that cooperate with the fixing bolts 15.

[0032] When the dehumidifier cylinder 10 absorbs moisture, its own weight increases. The pressure rod 17 moves downward under the gravity of the dehumidifier cylinder 10, generating pressure on the pressure sensor 17. The pressure sensor 17 transmits the pressure signal to the controller. The controller processes the pressure signal. When the pressure reaches a preset threshold, it is determined that the activated carbon in the dehumidifier cylinder 10 has absorbed a lot of moisture and its adsorption capacity has decreased. At this time, the controller indicator light will light up, prompting the user to replace the dehumidifier cylinder 10.

[0033] The dehumidifier box 2 has a sliding door rotatably connected to its front side. The contact area between the sliding door and the dehumidifier box 2 is provided with a sealing gasket. Rotating rods are rotatably connected to the inner walls of both the front and rear sides of the dehumidifier box 2. The adjacent sides of the two rotating rods are fixedly connected to the flip plate 12. The rotating rod located on the rear side extends to the outside and is fixedly connected to the second knob 6.

[0034] When the upper dehumidifier cylinder 10 fails and the indicator light illuminates, first use the first knob 5 to move the two moving plates 9 away from the connecting pipe 11, moving it away from the corresponding dehumidifier cylinder 10. Then, turn the second knob 6 to rotate the rotating rod, causing the flip plate 12 to flip 180 degrees, flipping the lower, unfailed dehumidifier cylinder 10 to the top. At this point, open the sliding door and use the connecting assembly to disassemble and replace the failed dehumidifier cylinder 10. After replacement, close the sliding door. Then, use the first knob 5 to move the two moving plates 9 to connect the connecting pipe 11 with the flipped dehumidifier cylinder 10.

[0035] The dehumidifier box 2 has a bidirectional lead screw 8 rotatably connected to its inner top and bottom. The bidirectional lead screw 8 passes through two movable plates 9, which are threadedly connected to the bidirectional lead screw 8. The two movable plates 9 are slidably connected to the inner right wall of the dehumidifier box 2. The upper end of the bidirectional lead screw 8 extends to the outside and is fixedly connected to a first knob 5.

[0036] When it is necessary to tightly connect or disconnect the connecting pipe 11 from the dehumidifier cylinder 10, turn the first knob 5 to rotate the bidirectional lead screw 8. Since the two moving plates 9 are threadedly connected to the bidirectional lead screw 8 and slidably connected to the inner wall of the right side of the dehumidifier box 2, under the action of the bidirectional lead screw 8, the two moving plates 9 will move towards or away from each other along the direction of the lead screw, thereby moving the connecting pipe 11 closer to or away from the dehumidifier cylinder 10. When the connecting pipe 11 is connected to the dehumidifier cylinder 10, a channel for air circulation is formed; when it is necessary to replace the dehumidifier cylinder 10, move the moving plates 9 to move the connecting pipe 11 away from the dehumidifier cylinder 10 for easy operation.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
