Description
Technical Field
[0001] The utility model relates to the technical field of clean air inflators, in particular to a bottle clean air inflator. Background Art
[0002] Coal mines in my country must perform daily calibration of their gas sensors every 7-10 days to ensure their normal operation and accurate and reliable measurement values. During daily calibration, clean ground air is an essential step in adjusting the electrical zero point of the methane sensor. However, how to fill the small gas cylinders with clean ground air has been a difficult problem faced by coal mines for many years. Through technological innovation, our company's scientific and technological personnel have developed the KDJ series clean air inflator, which is compatible with the MAJ series mining sensor calibration device. This has perfectly solved this problem and provided another necessary equipment for the smooth daily calibration of mining gas sensors.
[0003] The current bottle clean air inflators on the market have the following problems when in use:
[0004] 1. When using a traditional bottle clean air inflator, a compressor switch is provided on the inflator to control the compressor to inflate the bottle. Since the internal force of the inflator needs to be controlled within a certain range, the switch will be controlled to shut down the compressor when the rated pressure is reached. If the switch is accidentally touched after the inflator is shut down and the compressor continues to work, the internal pressure of the inflator will exceed the standard, posing a certain safety hazard.
[0005] 2. When most bottle clean air inflators are used, a handle is provided on the top of the inflator to facilitate the staff to pick up and move it. However, if the inflator is not handled properly when carried, the corners may collide with other objects. Due to the lack of protective structure on the corners, the inflator may be damaged, affecting the normal use of the staff. Utility Model Content
[0006] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.
[0007] The present utility model is proposed to solve the above-mentioned problems that if the switch is accidentally touched and the compressor continues to work, the internal pressure of the inflator will exceed the standard, which poses certain safety hazards. In addition, if the inflator is improperly operated when carried, it may cause the corners of the inflator to collide with other objects. Due to the lack of protective structure at the corners, the inflator may be easily damaged, affecting the normal use of the staff.
[0008] Therefore, the purpose of the present utility model is to provide a bottle clean air inflator, which can avoid the safety hazard caused by excessive pressure inside the inflator due to accidental touching of the switch, and secondly, it can avoid damage to the inflator due to bumps to a great extent, and will not affect the normal use of the staff.
[0009] The technical solution is:
[0010] It includes a body, a slide groove is provided on the top of the body, a slider is provided inside the slide groove, a connecting plate is installed on the top of the slider, a baffle is installed on the outside of the connecting plate, a threaded hole is provided inside the connecting plate, a threaded rod is threadedly connected to the threaded hole, a knob is installed on the top of the threaded rod, a socket is provided on the top of the body, the bottom of the threaded rod is inserted into the socket, a compressor switch is installed on the outside of the body, and the compressor switch is located on the side of the baffle.
[0011] As a preferred solution of the utility model for a bottle clean air inflator, a sliding rod is installed on the outside of the body, a spring is fixedly connected to the outside of the body, the other end of the spring is fixedly connected to the surface of the guard plate, a sliding hole is opened inside the guard plate, a sliding rod is movably connected inside the sliding hole, and a rubber pad is provided on the outside of the guard plate.
[0012] As a preferred solution of the bottle clean air inflator of the utility model, a fixing block is installed at the bottom of the machine body, and a handle is installed at the top of the fixing block.
[0013] As a preferred solution of the bottle clean air inflator of the utility model, a pressure gauge is provided on the top of the machine body, and a temperature indicator is provided on the top of the machine body.
[0014] As a preferred solution of the bottle clean air inflator of the utility model, a heat dissipation hole is opened on the side of the body, and a dustproof net is installed inside the heat dissipation hole.
[0015] As a preferred solution of the bottle clean air inflator of the utility model, a fixing ring is installed on the side of the machine body, and an air pipe is provided inside the fixing ring.
[0016] The beneficial effects of the utility model are as follows: compared with the prior art, with this type of bottle clean air inflator, after turning off the compressor switch, the connecting plate can be moved by screwing the slider and the slide groove until the bottom of the threaded rod is aligned with the insertion hole, and then the knob is turned to screw the threaded rod downward inside the threaded hole, so that the bottom of the threaded rod is inserted into the insertion hole. At the same time, the baffle will also cover the compressor switch. In this way, after stopping the compressor, it is possible to avoid the safety hazard of accidentally touching the switch to start the compressor, thereby preventing the internal pressure of the inflator from being excessively high.
[0017] If this type of bottle clean air inflator collides with other objects due to improper operation, it will first collide with the rubber pad of the inflator's external guard plate, which can provide preliminary buffering of the collision force. After that, the collision force will squeeze the guard plate, causing the guard plate to slide on the slide rod through the sliding hole and compress the spring. The energy storage effect of the spring can effectively buffer the collision force again, thus avoiding damage to the inflator due to collision to a great extent and will not affect the normal use of the staff.

[0031] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0032] The utility model provides a schematic diagram of the overall structure of an embodiment of a bottle clean air inflator, comprising:
[0033] See also Figure 1-Figure 7, a bottle clean air inflator of this embodiment includes a body 1, a slide groove 8 is opened on the top of the body 1, a slider 10 is arranged inside the slide groove 8, a connecting plate 11 is installed on the top of the slider 10, a baffle 14 is installed on the outside of the connecting plate 11, a threaded hole 15 is opened inside the connecting plate 11, a threaded rod 12 is threadedly connected to the threaded hole 15, a knob 13 is installed on the top of the threaded rod 12, a socket 9 is opened on the top of the body 1, the bottom of the threaded rod 12 is inserted into the socket 9, a compressor switch 18 is installed on the outside of the body 1, and the compressor switch 18 is located on the side of the baffle 14. When the compressor is turned off, the compressor switch 18 is turned off. After turning off the compressor switch 18, the knob 13 can be turned so that the bottom of the threaded rod 12 is no longer in contact with the surface of the inflator, and then the connecting plate 11 can be moved by the slider 10 and the slide groove 8 until the bottom of the threaded rod 12 is aligned with the socket 9. Then, the knob 13 is turned so that the threaded rod 12 is screwed downward inside the threaded hole 15, and the bottom of the threaded rod 12 is inserted into the socket 9 to fix the connecting plate 11. At the same time, the baffle 14 will also cover the compressor switch 18. In this way, after stopping the compressor, the safety hazard caused by excessive pressure inside the inflator due to accidental touching of the switch can be avoided.
[0034] The spring 22 is pressed against the outer edge of the protective plate 20 to prevent the inflator from being damaged by collision.
[0035] Next, in order to facilitate the lifting and holding of the inflator, specifically, a fixing block 2 is installed at the bottom of the body 1, and a handle 3 is installed on the top of the fixing block 2. The fixed block 2 and the handle 3 structure make it convenient for staff to lift and hold the inflator.
[0036] At the same time, in order to facilitate the control of the inflator based on data, specifically, a pressure gauge 6 is provided on the top of the body 1, and a temperature indicator 7 is provided on the top of the body 1. Through the structure of the pressure gauge 6 and the temperature indicator 7, it is convenient for the staff to observe the data to control the inflator.
[0037] Furthermore, in order to effectively dissipate heat inside the inflator, specifically, a heat dissipation hole 4 is opened on the side of the body 1, and a dustproof net 5 is installed inside the heat dissipation hole 4. Through the structure of the heat dissipation hole 4 and the dustproof net 5, the heat inside the inflator is effectively dissipated and dust is better prevented from entering.
[0038] It is worth noting that in order to inflate the inside of the bottle, specifically, a fixing ring 16 is installed on the side of the body 1, and an air pipe 17 is provided inside the fixing ring 16. Through the structure of the fixing ring 16 and the air pipe 17, the effect of inflating the inside of the bottle is better achieved.
[0039] Combine Figure 1-Figure 7 The specific use process of the bottle clean air inflator of this embodiment is as follows:
[0040] 1: According to actual usage, first, a slide groove 8 can be opened on the top of the body 1, and a slider 10 can be provided inside the slide groove 8. A connecting plate 11 is installed on the top of the slider 10. Then, a baffle 14 is installed on the outside of the connecting plate 11. A threaded hole 15 is opened inside the connecting plate 11, and the threaded rod 12 is threadedly connected inside the threaded hole 15. Then, a knob 13 is installed on the top of the threaded rod 12. A socket 9 is opened on the top of the body 1, and the bottom of the threaded rod 12 is inserted into the socket 9. A compressor switch 18 is installed on the outside of the body 1, and the compressor switch 18 is located on the side of the baffle 14.
[0041] 2: When the internal pressure of the inflator reaches a certain range, after turning off the compressor switch 18, the knob 13 can be turned so that the bottom of the threaded rod 12 is no longer in contact with the surface of the inflator, and then the connecting plate 11 is moved by the slider 10 and the slide groove 8 until the bottom of the threaded rod 12 is aligned with the socket 9. Then, the knob 13 is turned so that the threaded rod 12 is screwed downward inside the threaded hole 15, and the bottom of the threaded rod 12 is inserted into the socket 9 to fix the connecting plate 11. At the same time, the baffle 14 will also cover the compressor switch 18. In this way, after stopping the compressor, it can avoid the safety hazard caused by accidentally touching the switch to start the compressor, thereby causing excessive pressure inside the inflator;
[0042] 3: Finally, a slide bar 19 can be installed on the outside of the body 1, and a spring 22 can be fixedly connected to the outside of the body 1. The other end of the spring 22 is fixedly connected to the surface of the guard plate 20. A slide hole 21 is opened inside the guard plate 20, and then the slide bar 19 is movably connected inside the slide hole 21. A rubber pad 23 is provided on the outside of the guard plate 20. In this way, when the staff carries the inflator, if the inflator collides with other objects due to improper operation, it will first collide with the rubber pad 23 of the outer guard plate 20 of the inflator, which can provide a preliminary buffering of the collision force. After that, the collision force will squeeze the guard plate 20 so that the guard plate 20 slides on the slide bar 19 through the slide hole 21 and compresses the spring 22. The energy storage effect of the spring 22 can effectively buffer the collision force again. In this way, when the inflator collides with other objects, the protective structure at the corners can effectively buffer the collision force, thereby avoiding damage to the inflator to a great extent and not affecting the normal use of the staff.
