Description

air gun Technical Field

[0001] This invention relates to an air gun, specifically an air gun that controls airflow by pressing, and which can be additionally equipped with an extension tube to increase the operating distance. Prior Technology

[0002] Air guns are suitable for many applications, such as home cleaning, cleaning wood or metal shavings in factories, cleaning corners of motorcycle storage compartments, and cleaning car seats. Furthermore, air guns are the best cleaning tool for irregularly shaped areas or situations where using ordinary cleaning tools is time-consuming.

[0003] Most air guns on the market today have fixed barrels with a fixed nozzle shape and position, resulting in overly concentrated airflow, making them more suitable for general spot dust removal. Using fixed barrels in large-scale work environments consumes a lot of time and energy and is inconvenient for the user. Increasing the nozzle diameter, on the other hand, causes airflow to spill, making it difficult to move stubborn dust, metal shavings, or wood chips from processing plants, hindering the use of the air gun. Furthermore, traditional air guns cannot be adjusted for deep, narrow, or high locations that are difficult to reach by hand, often requiring external tools for assistance.

[0004] Therefore, based on the problems observed above, the creator of this invention sought to improve upon the shortcomings of existing technologies. After continuous testing and verification, the creator finally successfully developed the air gun of this invention. Summary of the Invention

[0005] To address the problems of the aforementioned prior art, this invention provides an air gun whose main purpose is to offer a technology that improves air blowing efficiency and helps users clean areas with complex environmental structures.

[0006] This invention is an air gun, and another purpose is to provide an additional extension tube to increase the usage distance, help users clean narrower areas, or reduce the frequency of users bending over or squatting to clean.

[0007] This invention is intended to provide an air gun and a valve body with a simple structure, which helps to improve production efficiency and reduce parts costs.

[0008] This invention relates to an air gun, comprising: a valve body, one end of which is an air inlet and the other end of which is an air outlet, with a ventilation channel between the two ends, and internal threads provided at both ends; a push-button switch that penetrates the valve body in a vertical direction to control air intake through the ventilation channel; the air inlet of the valve body being connected to an air supply pipeline; a connector, one end of which is connected to the air outlet of the valve body; a tube, one end of which is connected to the connector, and when gas enters from the air inlet pipe, the gas is blown out from the other end of the tube; and an air outlet cover, which is a hollow tube, narrow at one end and gradually expanding outward into a trumpet shape at the other end, the narrower end being connected to the connector; wherein the two ends of the connector are respectively provided with a first internal thread and a first external thread, which can be connected to the valve body, the tube, and the air outlet cover.

[0009] The push-button switch includes: a stop cap with a receiving groove and a second external thread on the outside of the receiving groove, which is connected to a second internal thread corresponding to the valve body; a first sealing ring fitted on the stop cap for airtight connection; a spring disposed in the receiving groove for rebound to close the air intake pipe; and a push rod, which is a cylindrical body with one end abutting against the spring and a second sealing ring near the spring for sealing the air intake port, and a third sealing ring between the two ends.

[0010] The push rod is connected to a button on the valve body. A through hole is provided on the side of the push rod, and the button is locked to the push rod by a screw.

[0011] This invention further includes at least one extension tube, which is a hollow tube with internal threads at both ends. It is connected to the valve body via the connector, or to another extension tube or the air inlet cover via the connector.

[0012] One end of the valve body near the air inlet is provided with an anti-slip part.

[0013] The piping system consists of a connector and a flexible hose, with one end of the connector screwed into the internal thread of the connector.

[0014] The valve body is equipped with a retaining ring.

[0015] This air gun has the following advantages compared to existing technology: 1. When air enters through the air inlet, the outer cover of the air outlet helps to limit the swing distance of the tube, presenting a cyclone-like blowing effect, thereby improving the efficiency and range of the blowing. 2. The extension tube can increase the range and situations in which it can be used, making it suitable for occasions with different distances. 3. The simple structure of the push rod reduces manufacturing difficulty, defect rate, and parts cost. Simple Explanation of the Diagram

[0020] Please refer to Figure 1, which is a structural schematic diagram of the valve body of this invention. The valve body 100 is provided with an air inlet 101 and an air outlet 102. In this embodiment, the air inlet 101 and the air outlet 102 are located at both ends of the valve body 100. A push switch 200 is provided vertically through the valve body 100, and internal threads 104 are provided at both ends of the valve body 100. In the state where no air is inlet, the vent 103 is sealed by the second sealing ring 241. When the user presses the push switch 200, the push rod 240 will compress the spring 230, and the second sealing ring 241 will move with the push rod 240. At this time, the vent 103 is in a free-flowing state, that is, the air inlet 101 and the air outlet 102 are connected.

[0021] The valve body 100 and push-button switch 200 of this invention have a simple structure, are easy to assemble, and can reduce the failure rate during operation. This embodiment includes: a stop cap 210, a first sealing ring 213, a spring 230, a second sealing ring 241, a push-button 240, a third sealing ring 242, a button 250, and a screw 260. The valve body 100 is provided with a second internal thread 220, and the stop cap 210 is provided with a receiving groove 211 and a second external thread 212. The stop cap 210 is fitted with the first sealing ring 213, and the spring 230 is placed in the receiving groove 211. The push-button 240 is fitted with the second sealing ring 241 and the third sealing ring 242. Then, the push-button 240 passes through the valve body 100, locking the stop cap 210, which contains the spring 230 and the first sealing ring 213, to the valve body 100. The push-button 250 is fitted onto the push-button 240 and secured with the screw 260 for easy use.

[0022] Please refer to Figure 2, which is a schematic diagram of the air gun of this invention. The air gun includes: a valve body 100, a push switch 200, a connector 300, and an air port cover 500. The internal thread 104 of the air outlet 102 end of the valve body 100 is screwed to the first external thread 320 of one end of the connector 300, and the first external thread 320 of the other end of the connector 300 is screwed to the air port cover 500.

[0023] Please refer to Figure 3, which is a schematic diagram of the exploded view of the air gun of this invention, including: valve body 100, push switch 200, connector 300, tube body 400, air port cover 500, extension tube 600, fourth sealing ring 700, and retaining ring 800. The tube body 400 consists of a connector 410 and a hose 420. One end of the connector 410 has an external thread 411, which is screwed onto the first internal thread 310 of the connector 300. The hose 420 is fitted onto the other end of the connector 410. The extension tube 600 is a hollow tube with internal threads 610 at both ends, which can be screwed onto the connector 300, valve body 100, or air port cover 500.

[0024] Preferably, a fourth sealing ring 700 can be fitted on both ends of the connector 300 to help improve the airtightness. The connector 300 can also be provided with anti-slip texture 330, which can be surface embossing, random texture, product markings or model numbers, etc., and can also be modified in shape, such as hexagon, to facilitate locking.

[0025] Optionally, the 800 series buckle is designed to facilitate users in hanging, storing, and carrying the air gun.

[0026] One end of the connector 300 is provided with a first internal thread 310 and a first external thread 320, which is used for connecting the tube body 400 and the air outlet cover 500. The external thread 411 of the tube body 400 is connected to the first internal thread 310, and the air outlet cover 500 is connected to the first external thread 320.

[0027] When the air gun is in use, the air nozzle cover 500 is a hollow tube. One end is narrower and connects to the connector 300, while the other end gradually expands outwards in a funnel shape, allowing airflow to be expelled. The hose 420 will swing due to inertia. The outlet shape of the air nozzle cover 500 limits the swinging range, creating a cyclone-like rotation. This increases the airflow range of the air gun and improves upon the problem of traditional air guns having a fixed nozzle shape and position, resulting in overly concentrated airflow.

[0028] Please refer to Figures 4A and 4B, which are schematic diagrams of the air gun connected to the extension tube 600 of this invention. By connecting at least one extension tube 600, the working distance of the air gun can be extended, and it can be applied to different occasions with different needs.

[0029] Please refer to Figures 5A and 5B, which are schematic diagrams of another embodiment of the air gun of this invention, showing another way of holding it. The valve body 100 has a hollow pipe. The bottom end of the valve body 100 is connected to the air supply line, and the other end is equipped with a push-button switch 200 to control the air intake of the air supply line. An air outlet (not shown in the figures) is opened on the periphery of the valve body 100 and connected to the connector 300, which in turn connects to the pipe body 400 and the air outlet cover 500. Furthermore, an anti-slip part 110 is provided on one end of the valve body 100 near the air inlet (not shown in the figures). The anti-slip part 110 can be one or a combination of embossing, multiple grooves, or multiple protrusions, and can be arranged regularly or irregularly.

[0030] When installing the extension tube, the process is the same as in the aforementioned embodiments, and will not be repeated here.

[0031] In summary, the key features of this air gun are its two grip options, extended operating distance, and simplified valve body 100 design, facilitating assembly and reducing costs and defect rates. During blowing, the flared shape of the nozzle cover 500 and the inertial swing of the hose 420 create a cyclone-like blowing effect, increasing the blowing range, improving efficiency, and reducing energy consumption. Suitable for various occasions, it also features a buckle 800 for storage and portability.

[0032] The above content only illustrates some embodiments of this invention, but is not intended to limit the scope of this invention. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this invention, and all such modifications and improvements are within the scope of protection of this invention.
