Description

Technical Field

[0001] This application relates to the field of air compressors, and more particularly to a lithium battery air compressor. Background Art

[0002] An air compressor is a common gas source device for compressing gases, usually powered by alternating current, with poor portability. There is an urgent need in the market for a new type of air compressor with stronger mobility and the ability to break free from the shackles of alternating current power supply. Therefore, an air compressor powered by a lithium battery has emerged. It is flexible and convenient to move, not affected by site power supply, and is more convenient to use.

[0003] For example, the utility model patent with the patent publication number CN215409113U discloses a lithium battery air compressor, which includes a base, a gas storage tank, an air compressor box body, a controller, and a lithium battery. The air compressor box body and the gas storage tank are connected and fixed to the base at the same time. The controller is fixed above the air compressor box body. An installation groove matching the shape of the lithium battery is provided at the rear of the air compressor box body. Two parallel positioning strips are vertically arranged on both sides in the installation groove. Positioning grooves matching the positioning strips are opened on the lithium battery. Jacks are opened in the installation groove. A jack sheet matching the jacks is vertically arranged below the lithium battery, having the advantages of good practicability and more convenient disassembly and assembly of the lithium battery.

[0004] Using the above lithium battery air compressor, since there is moisture in the air, after the gas storage tank is used for a long time, a large amount of accumulated water will be generated at the bottom of the gas storage tank. If this accumulated water cannot be drained in time, it will occupy the volume of the gas storage tank. Seriously, the accumulated water will fill the entire gas storage tank and flow back into the air compressor box body and enter the post-treatment equipment (dryer and filter), causing significant losses to the equipment. Therefore, it is necessary to drain the gas storage tank regularly, usually using a manual valve for drainage. Since the gas storage tank is usually in a horizontal state, when draining water, the internal accumulated water of the gas storage tank cannot be drained completely due to the too high water valve, which will corrode the tank body of the gas storage tank over time and shorten the service life of the gas storage tank, and needs to be improved. Summary of the Invention

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

[0006] A lithium battery air compressor provided by this application adopts the following technical solution:

[0007] A lithium battery air compressor includes a base, an air compressor box body and a gas storage tank provided on the base. An accommodation cavity is opened in the gas storage tank. An installation seat is provided on the gas storage tank. An accommodation groove is opened on the installation seat. The accommodation groove communicates with the accommodation cavity. A water collecting plate is provided on the gas storage tank. The water collecting plate is located in the accommodation cavity, and one end of the water collecting plate extends into the accommodation groove. The water collecting plate is inclined upward away from the installation seat.

[0008] By adopting the above technical solution, after the accumulated water in the gas storage tank is discharged through the manual valve, the remaining moisture in the gas storage tank will volatilize during the storage and use of the air compressor. The volatilized moisture will condense and accumulate when it meets the water collecting plate, and flow into the receiving groove along the water collecting plate for collection, thereby realizing the transfer of the remaining moisture from the gas storage tank to the mounting seat, shortening the contact time between the moisture and the gas storage tank, inhibiting the corrosion of the gas storage tank by the moisture, and being beneficial to extending the service life of the gas storage tank.

[0009] Optionally, the mounting seat includes a seat body provided on the gas storage tank and a sleeve block rotatably connected to the seat body. The receiving groove is provided on the seat body. A drain hole is provided on the seat body, and the drain hole communicates with the receiving groove. The sleeve block covers the drain hole. A through hole is provided on the outer side wall of the sleeve block. The through hole is located on one side of the drain hole along the rotation direction of the sleeve block, and the through hole is used to communicate with the drain hole.

[0010] By adopting the above technical solution, when it is necessary to discharge the accumulated water collected in the receiving groove, rotate the sleeve block to align the through hole with the drain hole. The accumulated water in the receiving groove is discharged through the drain hole and the through hole in sequence. After that, rotate the sleeve block again to make the sleeve block cover the drain hole again, making it more convenient to discharge the accumulated water collected in the receiving groove.

[0011] Optionally, a limiting block is provided on the seat body, and a limiting groove is provided on the sleeve block. The limiting block is slidably connected to the limiting groove in the opposite direction of the rotation direction of the sleeve block.

[0012] By adopting the above technical solution, the limiting block and the limiting groove are provided. The inner wall of the limiting groove abuts against the limiting block, thereby restricting the movement range of the sleeve block and preventing the sleeve block from detaching from the seat body.

[0013] Optionally, the seat body and the gas storage tank are threadedly connected.

[0014] 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 the seat body from the gas storage tank for replacement. There is no need to replace the entire gas storage tank, reducing material waste and being beneficial to extending the service life of the gas storage tank.

[0015] Optionally, an adjusting block is slidably connected to the seat body. The adjusting block slides closer to or farther away from the sleeve block, and the adjusting block passes through the sleeve block and rotates coaxially with the sleeve block. A positioning block is provided on the adjusting block, and a positioning groove for the positioning block to be inserted into is provided on the sleeve block. When the positioning block is located in the positioning groove, the sleeve block covers the drain hole. An elastic member is provided on the seat body, and the elastic member abuts against the adjusting block, so that the positioning block has a tendency to be inserted into the positioning groove.

[0016] 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, which reduces 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 the mounting seat needs to be replaced, 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 tank; when the accumulated water collected in the receiving groove needs to be discharged, 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.

[0017] Optionally, when the limiting block is located at one end of the limiting groove, the through hole is connected to the drainage hole; 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 is aligned with the positioning groove.

[0018] 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, so that it is more convenient to discharge the accumulated water collected in the receiving groove and to position the sleeve block.

[0019] Optionally, the gas storage tank includes a tank body disposed on the base and an annular protrusion disposed on the tank body, the accommodating cavity is formed by splicing the tank body and the annular protrusion, the water collecting plate is disposed on the annular protrusion, the base body and the annular protrusion are threadedly connected, the accommodating groove is disposed around the outer periphery of the annular protrusion, and the inner peripheral wall of the accommodating groove is inclined outward in a direction away from the tank body, and a plurality of water absorption grooves are circumferentially opened on the inner peripheral wall of the accommodating groove, and the water absorption grooves are located at one end of the accommodating groove away from the tank body.

[0020] 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 peripheral 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.

[0021] Optionally, the shortest distance between the water collecting plate and the receiving tank is 0-1 mm.

[0022] By adopting the above technical solution, the water on the water collecting plate can slide down the inner wall of the receiving groove into the receiving groove, which reduces 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.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After the accumulated water in the gas storage tank is discharged through the manual valve, the residual moisture in the gas storage tank will volatilize during the storage and use of the air compressor. The volatilized moisture will condense and accumulate when it encounters the water collecting plate, and flow along the water collecting plate into the receiving groove for collection, thereby realizing the transfer of the residual moisture from the gas storage tank to the mounting seat, shortening the contact time between the moisture and the gas storage tank, inhibiting the corrosion of the gas storage tank by the moisture, and being beneficial to extending the service life of the gas storage tank;

[0025] 2. When the mounting seat is damaged or corroded and cannot be used, the seat body can be removed from the gas storage tank for replacement, without replacing the entire gas storage tank, reducing material waste, and being beneficial to extending the service life of the gas storage tank;

[0026] 3. After the accumulated water collected in the receiving groove is discharged, when it is necessary to turn the seat body to remove the seat body subsequently, the residual moisture in the receiving groove flows along the inner peripheral wall of the receiving groove and is sucked into the water absorption groove under the capillary action, thereby reducing the situation where the residual moisture in the receiving groove splashes onto the annular convex block, and thus reducing the corrosion of the annular convex block.

Detailed implementation manners

[0036] The following further elaborates on this application Figure 1-8 in conjunction with the attached drawings.

[0037] The embodiment of this application discloses a lithium battery air compressor. Refer to Figure 1-3 , the lithium battery air compressor includes a base 1, an air compressor box body 2 and an air storage tank 3. The air compressor box body 2 is fixed on the base 1. The air storage tank 3 includes a tank body 31 and an annular convex block 32. The tank body 31 is in a horizontal state and is fixed on the base 1. The annular convex block 32 is located at one end of the tank body 31 in the horizontal direction and is fixedly connected to the tank body 31. The annular convex block 32 and the tank body 31 are spliced to form an accommodation cavity 4.

[0038] Refer to Figure 1-4 , an installation seat 5 is provided on the air storage tank 3. The installation seat 5 includes a seat body 51 and a sleeve block 52. The seat body 51 is threadedly connected to the annular convex block 32. An accommodation groove 511 is formed on the outer side wall of the seat body 51 close to the annular convex block 32. The accommodation groove 511 communicates with the accommodation cavity 4. The annular convex block 32 extends into the accommodation groove 511, and the accommodation groove 511 surrounds the outer circumference of the annular convex block 32. The inner circumferential wall of the accommodation groove 511 is inclined outward away from the tank body 31. A plurality of water absorption grooves 512 are circumferentially and evenly spaced on the inner circumferential wall of the accommodation groove 511. The water absorption grooves 512 are located at one end of the accommodation groove 511 away from the tank body 31.

[0039] Refer to Figure 1-4 , a drain hole 513 is formed on the outer side wall of the seat body 51. The drain hole 513 is located below the accommodation groove 511 and communicates with the accommodation groove 511. A water collecting plate 6 is fixed on the annular convex block 32. The water collecting plate 6 is located in the accommodation cavity 4, and one end of the water collecting plate 6 extends into the accommodation groove 511. The water collecting plate 6 is inclined upward away from the seat body 51. The shortest distance between the water collecting plate 6 and the inner wall of the bottom of the accommodation groove 511 is 0 - 1 mm.

[0040] Refer to Figure 1-6, the sleeve block 52 is located on the side of the seat body 51 away from the pipe body and is rotatably connected to the seat body 51. The rotation axis of the sleeve block 52 is horizontally arranged, and the sleeve block 52 covers the seat body 51 and covers the drain hole 513. A through hole 521 is formed on the outer side wall of the sleeve block 52. The through hole 521 is located on one side of the drain hole 513 along the rotation direction of the sleeve block 52, and the through hole 521 is used to communicate with the drain hole 513.

[0041] See Figure 1-6 , a limiting block 7 is fixed on the outer side wall of the seat body 51. A limiting groove 522 is formed on the outer side wall of the sleeve block 52 close to the seat body 51. The limiting block 7 is located in the limiting groove 522, and the opposite two ends of the limiting block 7 distributed along the rotation axis of the sleeve block 52 respectively abut against the opposite two inner walls of the limiting groove 522. When the sleeve block 52 rotates, the limiting block 7 is slidably connected in the limiting groove 522 in the opposite direction of the rotation direction of the sleeve block 52. By the inner wall of the limiting groove 522 abutting against the limiting block 7, the movement range of the sleeve block 52 is restricted, and the sleeve block 52 is prevented from detaching from the seat body 51.

[0042] See Figure 1-7 , a sliding groove 514 is formed on the outer side wall of the seat body 51 away from the tank body 31. An adjusting block 8 is slidably connected in the sliding groove 514. The adjusting block 8 slides closer 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 adjusting block 8 passes through the sleeve block 52 and rotates coaxially with the sleeve block 52, and the end face of the adjusting block 8 away from the tank body 31 is flush with the end face of the sleeve block 52 away from the tank body 31. In this embodiment, the cross section of the adjusting block 8 is circular.

[0043] See Figure 1-8 , a positioning block 9 is fixed on the adjusting block 8. The positioning block 9 is sleeved on the outer side of the adjusting block 8. A relief groove 515 is also formed on the outer side wall of the seat body 51 away from the tank body 31. The relief groove 515 is communicated with the sliding groove 514, and the relief groove 515 is for the positioning block 9 to be inserted into. A positioning groove 523 for the positioning block 9 to be inserted into is formed on the sleeve block 52. When the positioning block 9 is located in the positioning groove 523, the sleeve block 52 covers the drain hole 513. In this embodiment, a limiting convex block 11 is fixed on the outer side wall of the adjusting block 8. The limiting convex block 11 is located on the side of the positioning block 9 close to the tank body 31. A groove 12 for accommodating the limiting convex block 11 is formed on the seat body 51. The limiting convex block 11 is slidably connected in the groove 12 along the sliding direction of the adjusting block 8. By the limiting convex block 11 abutting against the inner wall of the groove 12, relative rotation between the adjusting block 8 and the seat body 51 is prevented.

[0044] See 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 is fixedly connected to the adjustment block 8, and the elastic member 10 is pressed 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.

[0045] 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 the positioning block 9 and the positioning groove 523, so that it is more convenient to discharge the accumulated water collected in the receiving groove 511 and to position the sleeve block 52.

[0046] The implementation principle of a lithium battery air compressor in the embodiment of the present application is:

[0047] 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 containing groove 511 along the water collecting plate 6 for collection, thereby realizing the transfer of the 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.

[0048] When it is necessary to discharge the accumulated water in the receiving groove 511, the adjusting block 8 is moved close to the seat body 51, so that the positioning block 9 is separated 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.

[0049] When the mounting seat 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 seat 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.

[0050] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
