In terms of household pipe unblocking, special unblocking tools are needed when the toilet or floor drain is blocked; when catching poultry, corresponding catching tools are needed; in fire emergency scenarios, firefighting tools that can quickly spray fire extinguishing media are needed. Traditional pneumatic tools usually have a single function. For example, a special unblocking pneumatic gun can only be used for pipe unblocking and cannot meet other needs such as catching or firefighting. The firefighting pneumatic gun is also limited to the fire extinguishing function and cannot be used for daily unblocking or catching operations.

[0003] This means that users need to purchase a variety of pneumatic tools with different functions, which not only increases costs but also takes up a lot of storage space. Moreover, in actual use, it is extremely inconvenient to frequently replace different pneumatic tools, especially in some emergency situations or scenarios where functions need to be switched quickly, the limitations of traditional pneumatic tools are more obvious. In addition, the operation of traditional pneumatic tools is also relatively complicated, and some require multiple operating steps or complex adjustment mechanisms to achieve their functions, which is easy to cause operational errors or delays for ordinary users or when used in emergency situations. Therefore, the development of a one-button multi-functional pneumatic gun has extremely important practical significance, which will greatly improve the practicality and convenience of pneumatic tools and meet the use needs of various scenarios.

The bottom of the air outlet pipe 8 passes through the housing 6 and communicates with the air groove 10. The top of the air inlet pipe 7 passes through the housing 6. A sealing sheet 11 is covered on the front of the housing 6. The sealing sheet 11 separates the inner side of the air groove 10 from the outer side of the air groove 10. The button 9 controls the gas in the air inlet pipe 7 to enter the air outlet pipe 8 by squeezing the sealing sheet 11.

[0045] The nozzle assembly is connected to the top of the air outlet pipe 8, and the nozzle assembly and the top of the air outlet pipe 8 are detachable structures.

[0046] The nozzle assembly is one of the dredging nozzle, the catching nozzle 2, and the fire sprinkler 3, which can be replaced according to different usage requirements. The nozzle assembly and the top of the air outlet pipe 8 are detachable structures, which is convenient for users to quickly replace nozzles with different functions according to actual needs and realize the switching of multiple functions.

[0047] The sealing sheet 11 includes a metal inner sheet 12 and a rubber sheet 13. The metal inner sheet 12 is fixed on the rubber sheet 13. The size of the metal inner sheet 12 corresponds to the air groove 10. The metal sheet is provided with a protrusion 14, and a spring 15 is fixed on the protrusion 14. The button 9 is fixed on the top of the spring 15. The switch assembly also includes a top cover 16, which is fixed on the outer shell 6.

[0048] The switch assembly includes a housing 6, an air inlet pipe 7, an air outlet pipe 8, and a button 9. An air groove 10 is provided in the middle of the housing 6, the bottom of the air outlet pipe 8 penetrates the housing 6 to communicate with the air groove 10, and the top of the air inlet pipe 7 penetrates the housing 6. A sealing sheet 11 is covered on the front of the housing 6, and the sealing sheet 11 separates the inner side of the air groove 10 from the outer side of the air groove 10, playing a key role in sealing the gas. The sealing sheet 11 includes a metal inner sheet 12 and a rubber sheet 13, and the metal inner sheet 12 is fixed on the rubber sheet 13. The size of the metal inner sheet 12 corresponds to the air groove 10 to ensure a good sealing effect. A protrusion 14 is provided on the metal sheet, and a spring 15 is fixed on the protrusion 14. The button 9 is fixed on the top of the spring 15. When the button 9 is pressed, the button 9 squeezes the sealing sheet 11 to deform the sealing sheet 11, thereby controlling the gas in the air inlet pipe 7 to enter the air outlet pipe 8, and realizing the opening and closing of the gas passage, which can be completed with only one-button operation, which is simple and convenient. The switch assembly also includes a top cover 16, which is fixed to the housing 6. The edge of the housing 6, the edge of the rubber sheet 13, and the edge of the top cover 16 are fixed by bolts. This structural design ensures the overall stability and sealing of the switch assembly.

[0049] The edge of the housing 6 , the edge of the rubber sheet 13 , and the edge of the top cover 16 are fixed by bolt connection.

[0050] The air pressure gun further comprises an air storage tank 17 , which is connected to the air outlet pipe 8 via a connecting piece 23 , on which a rotary pressure regulating knob 18 and an air filling nozzle 19 are provided.

[0051] An air pressure storage meter 20 is provided at the bottom of the air storage tank 17, and an air pressure usage meter 21 is provided at the bottom of the back side of the housing 6.

[0052] The gas tank 17 is connected to the air outlet pipe 8 through a connector 23, providing gas storage and supply functions for the air pressure gun. A rotating pressure regulating knob 18 and an air filling nozzle 19 are provided on the connector 23. The rotating pressure regulating knob 18 can be used to adjust the pressure of the gas output from the gas tank 17 to adapt to different usage scenarios and nozzle requirements. For example, the pressure can be appropriately increased when clearing stubborn blockages, and the pressure can be reduced when capturing more fragile targets to avoid damage to the target. The air filling nozzle 19 is convenient for inflating the gas tank 17 to ensure that the air pressure gun has sufficient gas reserves. An air pressure storage meter 20 is provided at the bottom of the gas tank 17, which can intuitively display the air pressure value in the gas tank 17, so that the user can understand the gas reserve situation in time and perform the inflation operation. An air pressure usage meter 21 is provided at the bottom of the back of the housing 6, which can display the air pressure situation during the current use process in real time, so that the user can adjust the operation according to the air pressure change or judge whether the device is working properly.

[0053] The capture nozzle 2 is provided with 6 uniformly fixed conduits 24 , and a capture net is fixed on the conduits 24 .

[0054] In this embodiment, the following is used: First, the gas storage tank 17 is inflated through the inflating nozzle 19, and the gas is stored in the gas storage tank 17. The air pressure storage meter 20 displays the air pressure value in the gas storage tank 17. When the air pressure gun is needed, a suitable nozzle assembly is selected according to the operation requirements and installed on the top of the outlet pipe 8. The button 9 of the switch assembly is pressed downward, and the button 9 squeezes the spring 15. The spring 15 drives the metal inner sheet 12 to deform the rubber sheet 13, thereby destroying the sealing state between the inside and outside of the gas groove 10. At this time, the gas in the air inlet pipe 7 enters the gas groove 10 under the action of the air pressure difference and flows to the nozzle assembly through the outlet pipe 8. When the gas passes through the nozzle assembly, the corresponding effect is produced according to the different functions of the nozzle. During use, the air pressure usage meter 21 displays the current air pressure in real time. The user can adjust the pressure of the gas output from the gas storage tank 17 by rotating the pressure adjustment knob 18 as needed to achieve the best operation effect. When the button 9 is released, the spring 15 returns to its original state, the sealing sheet 11 reseals the gas groove 10, the gas passage is closed, and the operation is stopped.

[0055] Example 2

[0056] This embodiment discloses a one-button multifunctional air pressure gun.

[0057] like Figure 2 , Fig.11 , Fig.12 As shown, this embodiment includes a pneumatic gun body 1, and the pneumatic gun body 1 includes a nozzle assembly and a switch assembly. The nozzle assembly of this embodiment is a fire sprinkler 3;

[0058] The switch assembly includes a housing 6, an air inlet pipe 7, an air outlet pipe 8, and a button 9. An air groove 10 is provided in the middle of the housing 6. The bottom of the air outlet pipe 8 passes through the housing 6 and communicates with the air groove 10. The top of the air inlet pipe 7 passes through the housing 6. A sealing sheet 11 is covered on the front of the housing 6. The sealing sheet 11 separates the inner side of the air groove 10 from the outer side of the air groove 10. The button 9 controls the gas in the air inlet pipe 7 to enter the air outlet pipe 8 by squeezing the sealing sheet 11.

[0059] The nozzle assembly is connected to the top of the air outlet pipe 8, and the nozzle assembly and the top of the air outlet pipe 8 are detachable structures.

[0060] The sealing sheet 11 includes a metal inner sheet 12 and a rubber sheet 13. The metal inner sheet 12 is fixed on the rubber sheet 13. The size of the metal inner sheet 12 corresponds to the air groove 10. The metal sheet is provided with a protrusion 14, and a spring 15 is fixed on the protrusion 14. The button 9 is fixed on the top of the spring 15. The switch assembly also includes a top cover 16, which is fixed on the outer shell 6.

[0061] The edge of the housing 6 , the edge of the rubber sheet 13 , and the edge of the top cover 16 are fixed by bolt connection.

[0062] The air pressure gun further comprises an air storage tank 17 , which is connected to the air outlet pipe 8 via a connecting piece 23 , on which a rotary pressure regulating knob 18 and an air filling nozzle 19 are provided.

[0063] An air pressure storage meter 20 is provided at the bottom of the air storage tank 17, and an air pressure usage meter 21 is provided at the bottom of the back side of the housing 6.

The film includes a top film 26 and a bottom film 27. The top film 26 is fixed to the top of the fire sprinkler by the fixing ring 25, and the bottom film 27 is adhered to the inner wall of the fire sprinkler.

[0065] The two layers of film tightly wrap the dry powder to form a stable dry powder storage and release system. The top film 26 can maintain structural integrity when subjected to a certain air pressure shock to prevent premature leakage of dry powder. It is firmly fixed to the top of the fire sprinkler through the fixing ring 25. The fixing ring 25 is made of stainless steel to ensure a close fit with the top of the sprinkler, providing a solid support point for the top film 26. The bottom film 27 is attached to the inner wall of the fire sprinkler. When in use, the internal air pressure rises rapidly and is transmitted to the fire sprinkler. As the air pressure continues to rise, the pressure acting on the top film 26 gradually increases. When the critical pressure that the film can withstand is reached, the top film 26 ruptures first. Due to the instantaneous impact force generated by the rupture of the top film 26 and the subsequent continuous air pressure push, the bottom film 27 is immediately torn open, and the dry powder originally trapped between the two layers of film is engulfed by the high-speed airflow in a very short time, and is dispersed and sprayed accurately from the fire sprinkler to the fire source.

[0066] The fire sprinkler 3 is equipped with fire extinguishing dry powder, which can be quickly sprayed out in firefighting scenes to effectively extinguish fires. The main body of the fire sprinkler 3 is made of high temperature and pressure resistant metal materials, and is equipped with a fire extinguishing dry powder storage chamber. The volume of the chamber is determined according to the fire extinguishing requirements and the design parameters of the air pressure gun. Appropriate spray holes are set at the nozzle outlet. The size, number and distribution of the spray holes must ensure that the fire extinguishing dry powder can be sprayed out evenly and quickly.
