Description

Technical Field

[0001] The present application relates to the field of air compressors, and in particular to a lithium battery air compressor. Background Art

[0002] An air compressor is a common gas source device used to compress gas. It usually uses alternating current as its power supply and has poor portability. The market is in urgent need of a new type of air compressor that is more mobile and can be free from the constraints of AC power supply. Therefore, lithium battery-powered air compressors came into being. They are flexible, easy to carry, not affected by site power supply, and more convenient to use.

[0003] For example, the utility model patent with patent announcement number CN215409113U discloses a lithium-ion air compressor, including a base, an air tank, an air compressor housing, a controller and a lithium battery. The air compressor housing and the air tank are connected and fixed on the base at the same time, the controller is fixed on the top of the air compressor housing, and a mounting groove matching the shape of the lithium battery is provided at the rear of the air compressor housing, and positioning strips parallel to each other are vertically provided on both sides of the mounting groove. A positioning groove matching the positioning strip is provided on the lithium battery, and a socket is provided in the mounting groove. A connector matching the socket is vertically provided below the lithium battery. The compressor has the advantages of good practicality and more convenient disassembly and assembly of the lithium battery.

[0004] When using the above-mentioned lithium-ion air compressor, since the air contains moisture, a large amount of water will accumulate at the bottom of the gas tank after long-term use. If the accumulated water cannot be drained in time, it will occupy the volume of the gas tank. In severe cases, the accumulated water will fill the entire gas tank and flow back to the air compressor case and enter the post-processing equipment (dryer and filter), causing significant damage to the equipment. Therefore, the gas tank needs to be drained regularly, and a manual valve is generally used for drainage. Since the gas tank is usually in a horizontal state, the water inside the gas tank cannot be completely drained due to the water valve being too high during drainage, which will corrode the gas tank body for a long time and shorten the service life of the gas tank, which needs to be improved. Summary of the invention

[0005] In order to extend the service life of the gas storage tank, the present application provides a lithium battery air compressor.

[0006] The present application provides a lithium battery air compressor, which adopts the following technical solution: A lithium battery air compressor comprises a base, an air compressor case and an air tank arranged on the base, wherein a accommodating cavity is defined in the air tank, a mounting seat is provided on the air tank, a accommodating groove is defined on the mounting seat, the accommodating groove is communicated with the accommodating cavity, a water collecting plate is provided on the air tank, the water collecting plate is located in the accommodating cavity, one end of the water collecting plate extends into the accommodating groove, and the water collecting plate is inclined upward in a direction away from the mounting seat.

[0007] By adopting the above technical solution, after the accumulated water in the gas tank is discharged through the manual valve, the residual water in the gas tank will evaporate during the storage and use of the air compressor. The evaporated water condenses and gathers when it meets the water collecting plate, and flows into the receiving tank along the water collecting plate for collection, thereby realizing the transfer of residual water from the gas tank to the mounting seat, thereby shortening the contact time between the water and the gas tank, inhibiting the corrosion of the water to the gas tank, and helping to extend the service life of the gas tank.

[0009] By adopting the above technical solution, when it is necessary to discharge the accumulated water in the receiving tank, the sleeve block is rotated so that the through hole and the drainage hole are aligned, and the accumulated water in the receiving tank is discharged through the drainage hole and the through hole in turn. After completion, the sleeve block is rotated again so that the sleeve block covers the drainage hole again, making it more convenient to discharge the accumulated water in the receiving tank.

[0010] Optionally, a limit block is provided on the seat body, and a limit slot is provided on the sleeve block, and the limit block is slidably connected in the limit slot in the opposite direction to the rotation direction of the sleeve block.

[0011] By adopting the above technical solution, a limit block and a limit groove are provided, and the inner wall of the limit groove abuts against the limit block, thereby limiting the range of movement of the sleeve block and preventing the sleeve block from separating from the seat body.

[0012] Optionally, the seat body and the gas storage tank are threadedly connected.

[0013] By adopting the above technical solution, when the mounting seat is damaged or corroded and cannot be used, the seat body can be twisted to remove it from the gas tank for replacement, without replacing the entire gas tank, thus reducing material waste and helping to extend the service life of the gas tank.

[0014] Optionally, an adjusting block is slidably connected to the seat body, the adjusting block slides close to or away from the sleeve block, and the adjusting block passes through the sleeve block and rotates coaxially with the sleeve block, the adjusting block is provided with a positioning block, and the sleeve block is provided with a positioning groove for the positioning block to be inserted into, when the positioning block is located in the positioning groove, the sleeve block covers the drainage hole, and an elastic member is provided on the seat body, the elastic member presses against the adjusting block, so that the positioning block has a tendency to be inserted into the positioning groove.

[0015] By adopting the above technical solution, the sleeve block is positioned by abutting the inner wall of the positioning groove through the positioning block, and the sleeve block is kept in a state of covering the drainage hole, thereby reducing the situation where the sleeve block is accidentally touched, causing the through hole and the drainage hole to be connected and causing the accumulated water in the receiving groove to leak out; when it is necessary to replace the mounting seat, the sleeve block is twisted, and the sleeve block abuts the positioning block through the inner wall of the positioning groove, which can drive the adjustment block and the seat body to twist together, so as to remove the seat body from the gas storage tank; when it is necessary to discharge the accumulated water collected in the receiving groove, the adjustment block is moved close to the seat body, so that the positioning block is separated from the positioning groove, and the sleeve block can be rotated to align the through hole and the drainage hole.

[0016] Optionally, when the limiting block is located at one end of the limiting groove, the through hole and the drainage hole are connected; when the limiting block is located at the other end of the limiting groove, the through hole and the drainage hole are staggered and the positioning block and the positioning groove are aligned.

[0017] By adopting the above technical solution, the two opposite inner walls of the limiting groove are respectively abutted against the limiting blocks to align the through hole and the drainage hole or the positioning block and the positioning groove, making it more convenient to discharge the accumulated water collected in the receiving groove and to position the sleeve block.

[0019] By adopting the above technical solution, after the accumulated water collected in the receiving groove is discharged, there may still be residual water adhering to the inner wall of the receiving groove. When the seat body needs to be twisted to remove the seat body later, the residual water in the receiving groove flows along the inner circumferential wall of the receiving groove and is sucked into the water absorption groove under the action of capillary, thereby reducing the water retained on the inner wall of the receiving groove, and further reducing the situation where the residual water in the receiving groove splashes onto the annular protrusion during the twisting process of the seat body, thereby reducing the corrosion of the annular protrusion.

[0020] Optionally, the shortest distance between the water collecting plate and the containing groove is 0-1 mm.

[0021] By adopting the above-mentioned technical solution, the water on the water collecting plate can slide down along the inner wall of the receiving groove into the receiving groove, thereby reducing the situation where the water on the water collecting plate drips into the receiving groove, causing the water in the receiving groove to splash and wet the annular protrusion, which helps to further reduce the corrosion of the annular protrusion.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the accumulated water in the gas tank is discharged through the manual valve, the residual water in the gas tank will volatilize during the storage and use of the air compressor. The volatilized water will condense and gather when it meets the water collecting plate, and flow into the containing tank along the water collecting plate for collection, thereby realizing the transfer of the residual water from the gas tank to the mounting seat, thereby shortening the contact time between the water and the gas tank, inhibiting the corrosion of the water to the gas tank, and helping to extend the service life of the gas tank; 2. When the mounting seat is damaged or corroded and cannot be used, the seat body can be removed from the gas tank for replacement without replacing the entire gas tank, which reduces material waste and helps to extend the service life of the gas tank; 3. After the accumulated water in the receiving tank is discharged, when the seat body needs to be twisted to remove it, the remaining water in the receiving tank flows along the inner wall of the receiving tank and is sucked into the water absorption groove under the action of capillary, thereby reducing the residual water in the receiving tank from splashing onto the annular protrusion, thereby reducing the corrosion of the annular protrusion.

The limiting block 7 is located in the limiting groove 522, and the opposite ends of the limiting block 7 distributed along the rotation axis of the sleeve block 52 respectively abut against the two opposite inner walls of the limiting groove 522. When the sleeve block 52 rotates, the limiting block 7 slides in the opposite direction of the rotation direction of the sleeve block 52 and is connected to the limiting groove 522. The inner wall of the limiting groove 522 abuts against the limiting block 7, thereby limiting the range of movement of the sleeve block 52 and preventing the sleeve block 52 from separating from the seat body 51.

[0038] See also Figure 1-7 A slide groove 514 is provided on the outer wall of the seat body 51 away from the tank body 31, and an adjusting block 8 is slidably connected in the slide groove 514. The adjusting block 8 slides close to or away from the sleeve block 52, and the sliding direction of the adjusting block 8 is parallel to the rotation axis of the sleeve block 52.

The limiting protrusion 11 is located on the side of the positioning block 9 close to the tank body 31. A groove 12 for accommodating the limiting protrusion 11 is provided on the seat body 51. The limiting protrusion 11 is slidably connected to the groove 12 along the sliding direction of the adjusting block 8. The limiting protrusion 11 abuts against the inner wall of the groove 12, thereby preventing relative rotation between the adjusting block 8 and the seat body 51.

[0040] See also Figure 1-3An elastic member 10 is fixed on the seat body 51. The elastic member 10 is located in the slide groove 514 and between the bottom of the slide groove 514 and the adjustment block 8. The elastic member 10 and the adjustment block 8 are fixedly connected, and the elastic member 10 presses against the adjustment block 8, so that the positioning block 9 has a tendency to be stuck in the positioning groove 523. In this embodiment, the elastic member 10 is a spring.

[0041] When the limit block 7 is located at one end of the limit groove 522 along the rotation direction of the sleeve block 52, the through hole 521 and the drainage hole 513 are connected; when the limit block 7 is located at the other end of the limit groove 522 along the rotation direction of the sleeve block 52, the through hole 521 and the drainage hole 513 are staggered and the positioning block 9 and the positioning groove 523 are aligned. The two opposite inner walls of the limit groove 522 are respectively abutted against the limit block 7 to align the through hole 521 and the drainage hole 513 or align the positioning block 9 and the positioning groove 523, so that it is more convenient to discharge the accumulated water collected in the accommodating groove 511 and to position the sleeve block 52.

[0042] The implementation principle of a lithium battery air compressor in the embodiment of the present application is: After the accumulated water in the gas tank 3 is discharged through the manual valve, the residual water in the gas tank 3 will volatilize during the storage and use of the air compressor. The volatilized water will condense and gather when it meets the water collecting plate 6, and flow into the receiving groove 511 along the water collecting plate 6 to be collected, thereby realizing the transfer of residual water from the gas tank 3 to the mounting seat 5, thereby shortening the contact time between the water and the gas tank 3, inhibiting the corrosion of the water to the gas tank 3, and helping to extend the service life of the gas tank 3.

[0043] When it is necessary to discharge the accumulated water collected in the receiving groove 511, the adjusting block 8 is moved close to the seat body 51 so that the positioning block 9 is disengaged from the positioning groove 523, and then the sleeve block 52 is rotated until the limiting block 7 abuts against the inner wall of the limiting groove 522 so that the through hole 521 and the drainage hole 513 are aligned, and the accumulated water in the receiving groove 511 is discharged through the drainage hole 513 and the through hole 521 in turn. After completion, the sleeve block 52 is rotated in the opposite direction until the limiting block 7 abuts against the inner wall of the limiting groove 522 again. At this time, the positioning block 9 and the positioning groove 523 are aligned, and the adjusting block 8 is released. Under the action of the elastic member 10, the adjusting block 8 drives the positioning block 9 to be clamped into the positioning groove 523, and the positioning block 9 abuts against the inner wall of the positioning groove 523, thereby positioning the sleeve block 52, so that the sleeve block 52 covers the drainage hole 513 again and maintains the state of covering the drainage hole 513.

[0044] When the mounting base 5 is damaged or corroded and cannot be used, the sleeve block 52 can be directly twisted. The sleeve block 52 can abut the positioning block 9 through the inner wall of the positioning groove 523 to drive the adjustment block 8 and the seat body 51 to twist together, so that the mounting base 5 can be removed from the tank body 31 for replacement, without replacing the entire gas tank 3, reducing material waste and helping to extend the service life of the gas tank 3.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
