Description

Technical Field

[0001] The utility model relates to an air gun with an electric air pump. Background Art

[0002] A pneumatic air gun is a pre-compressed air type air gun (PCP), which combines the advantages of multiple pump types and single pump types. Its firing power can be high or low and adjustable. When shooting, remove the safety, apply pressure to the trigger with your finger until the trigger is pulled and released. At this time, the hammer advances rapidly with the power of the hammer spring, and suddenly pushes the air in the air compression chamber onto the bullet at the breech of the barrel, making it fly out of the barrel and shoot at the target.

[0003] At present, pneumatic air guns have been widely used in the market. However, each time it is used, it is necessary to inflate the gas cylinder (pre-compress air), which is very inconvenient. Moreover, after each bullet is fired, the pressure of the gas cylinder will drop. If you want to keep the firing air pressure constant, it is necessary to install a constant pressure device, which results in a relatively complex structure. Even if a constant pressure device is installed, after multiple bullets are fired, the pressure in the gas cylinder will continue to drop until it becomes normal pressure and cannot be used continuously. Therefore, the existing one needs to be further improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an air gun with an electric air pump that can realize the formation of a large amount of high-pressure gas and can continuously supply and use it.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An air gun with an electric air pump includes a barrel, a firing mechanism and a deflation mechanism arranged on an air gun bracket. An electric motor, a gear assembly and an air pump are also arranged on the air gun bracket. The gear assembly has an input shaft and an output shaft. The input shaft is butt-connected to the motor shaft of the electric motor, and the output shaft is hinged to the first end of a connecting rod. The air pump includes an air cylinder and a moving part arranged in the air cylinder. An intake one-way air valve and an outlet one-way valve are correspondingly arranged at the intake port and the outlet port of the air cylinder. A moving rod is hinged to the second end of the connecting rod. The input shaft rotates under the action of the electric motor to make the output shaft perform a circular motion, driving the connecting rod to swing, so that the moving rod acts on the moving part to move back and forth in the air cylinder. The outlet port of the air cylinder is communicated with the deflation mechanism.

[0007] The advantage of the utility model is that it can realize the formation of a large amount of high-pressure gas and can continuously supply the air gun for use. Brief Description of the Drawings

[0018] As shown in Figure 1 to Figure 6 shown, an air gun with an electric air pump includes a barrel 11, a firing mechanism 12, an air release mechanism 13, a motor 14, a gear assembly 2, and an air pump 5 provided on an air gun bracket.

[0019] A connecting seat assembly 15 is provided on the air gun bracket. The air release mechanism 13 and the barrel 11 are both installed and connected to the connecting seat assembly 15. The barrel 11, the firing mechanism 12, and the air release mechanism 13 are common existing structures, and the bullet is fired from the barrel 11 by the firing mechanism 12 through air release, which will not be elaborated here.

[0020] The motor 14 is a DC motor, and the DC motor is configured with a battery 16. More specifically, the motor 14 is a high-speed DC motor, and the voltage of the battery 16 is selected as 12V / 24V / 36V, etc. according to requirements.

[0021] The air gun bracket is also provided with a control assembly. The control assembly includes a circuit board bracket and a control device. The control device includes a circuit board and a touch display screen. The circuit board bracket is provided with a charging interface, and the circuit board is electrically connected to the battery 16, the DC motor, and the charging interface. The control device can preset the pressure value, stop automatically when full, provide overload protection, intelligent digital display, display multiple pressure units, and has a battery charging interface.

[0022] The circuit board is designed with a liquid crystal display screen, an on / off key, a return key, a up adjustment key, and a down adjustment key. The display screen has different pressure unit selections for the convenience of consumers to identify and can set the pressure value. The display screen E6 will display the size of the preset pressure, and display the instantaneous pressure of the inflation pressure, and stop when reaching the preset pressure.

[0023] The gear assembly 2 has an input shaft 21 and an output shaft 22. The input shaft 21 is butt-connected to the motor shaft of the motor 14, and the output shaft 22 is hinged to the first end of the connecting rod 3. The air pump 5 includes an air cylinder 51 and a moving part 521 arranged in the air cylinder 51. An intake one-way air valve 531 and an outlet one-way valve 532 are correspondingly arranged at the intake port and the outlet port of the air cylinder 51. A moving rod 522 is hinged to the second end of the connecting rod 3. The input shaft 21 rotates under the action of the motor 14 to make the output shaft 22 perform a circular motion to drive the connecting rod 3 to swing, so that the moving rod 522 acts on the moving part 521 to move back and forth in the air cylinder 51 (converting the circular motion into a reciprocating motion). The outlet port of the air cylinder 51 is communicated with the air release mechanism 13.

[0024] The air pump 5 can be a single-stage air pump, as shown in the appendix Figure 1 and the appendix Figure 4 As shown, the moving part 521 is a piston, and the moving rod 522 is a piston rod connected to the piston.

[0025] The air pump 5 can be a two-stage sleeve-type air pump, as shown in the appendix Figure 2 and the appendix Figure 5As shown, the air cylinder 51 can move back and forth along its axial direction and is arranged on the air gun bracket. An inner tube is coaxially arranged in the air cylinder 51. The inner tube is fixed on the air gun bracket. One end of the inner tube forms the air outlet of the air cylinder 51. An outer piston is fixedly arranged on the outer periphery of the inner tube. One end of the air cylinder 51 is fixedly provided with an end cap. The movable rod 522 is fixedly installed on the end cap and one end extends into the inner tube. A one-way valve is arranged between the air cylinder 51 and the inner tube. A plunger is fixedly arranged in the inner tube to form the movable part 521.

[0026] During use, when the movable rod 522 moves forward under the action of the connecting rod 3, on the one hand, it drives the air cylinder 51 to move forward. The outer piston compresses the gas between the air cylinder 51 and the inner tube (the first chamber) and forces the one-way valve to open and enter the second chamber in the inner tube (on one side of the plunger in the inner tube) for primary pressure boost. On the other hand, the movable rod 522 acts on the gas in the third chamber on the other side of the plunger in the inner tube. The inlet pipe valve of the plunger closes and the outlet pipe valve opens. The gas in the third chamber is compressed and boosted at the same time and then passes through the outlet one-way valve 532. When the movable rod 522 moves backward under the action of the connecting rod 3, on the one hand, it drives the air cylinder 51 to move backward, and the external gas enters the first chamber. On the other hand, when the movable rod 522 retracts, the one-way valve closes, the outlet pipe valve of the plunger closes and the inlet pipe valve opens. The gas originally in the second chamber enters the third chamber through the plunger for the next compression and pressure boost.

[0027] The air pump 5 can be a three-stage sleeve-type air pump, as shown in the appendix Figure 3 and the appendix Figure 6 shown.

[0028] Specifically, further combined with the appendix Figure 7 and the appendix Figure 8 shown, the air cylinder 51 is internally provided with a middle tube 61 and a small tube 62. The small tube 62 is fixedly sleeved in the air cylinder 51 and is communicated with the air outlet of the air cylinder 51. A plunger 63 is fixedly arranged in the small tube 62. A fixed connection sleeve 64 is fixedly arranged on the outer periphery of the small tube 62. The middle tube 61 is hermetically sleeved on the fixed connection sleeve 64 and can move back and forth relative to the small tube 62 along the axial direction. One end of the middle tube 61 is fixedly provided with an end cap 65. The end cap 65 is fixedly connected with the movable rod 522. The movable rod 522 extends into the small tube 62. A through hole 66 is opened on the side wall of the small tube 62. The through hole 66 communicates the middle tube 61 and the small tube 62. A movable connection sleeve 67 is fixedly arranged on the outer periphery of the middle tube 61. The air cylinder 51 is hermetically sleeved on the movable connection sleeve 67. The middle tube 61 can move back and forth relative to the air cylinder 51 along the axial direction;

[0029] When the movable rod 522 moves backward, it drives the middle tube 61 and the movable connection sleeve 67 to move backward synchronously. A primary air chamber is formed between the movable connection sleeve 67 and the air cylinder 51; a secondary air chamber is formed between the middle tube 61 and the small tube 62; a tertiary air chamber is formed between the small tube 62 between the plunger 63 and the movable rod 522.

[0030] When the movable rod 522 moves backward, the inhalation one-way air valve 531 opens the air inlet of the air cylinder 51, and the gas enters the primary air chamber from the air inlet of the air cylinder 51; when the movable rod 522 moves forward, the middle tube 61 and the movable connecting sleeve 67 move forward synchronously, and the inhalation one-way air valve 531 closes the air inlet of the air cylinder 51, and the gas in the primary air chamber is squeezed and pressurized and enters the secondary air chamber; when the movable rod 522 moves backward again, the gas continues to enter the primary air chamber from the air inlet of the air cylinder 51 The gas in the primary air chamber is squeezed and pressurized and enters the secondary air chamber. The inlet pipe valve of the plunger 63 is closed and the outlet pipe valve is opened. The gas in the tertiary air chamber is squeezed and pressurized and then flows into the secondary air chamber. The inlet pipe valve of the plunger 63 is closed and the outlet pipe valve is opened. The gas in the tertiary air chamber is squeezed and pressurized and then flows into the outlet pipe valve 532.

[0031] The air pump 5 of the above-mentioned embodiment adopts a one- to three-stage air pump. Of course, the air pump 5 can also be an air pump with more than three stages. Such reciprocating motion realizes the formation of large volume and high-pressure gas, which is stored in the air storage chamber 7 of the air chamber tube assembly described below, providing the gun with high-pressure gas energy.

The lower teeth are meshed and transmission-connected with the bevel gear 24, and the upper teeth are meshed and transmission-connected with the output gear 26. The central axis of the output gear 26 is the output shaft 22.

[0033] The motor shaft and piston rod of the motor 14 can also be coaxially arranged on the air gun bracket, as shown in the attached Figure 4 To Attachment Figure 6 As shown in FIG. 1 , compared with the side-by-side parallel arrangement, the gun body can be made more slender; at this time, the gear assembly 2 includes a gear box 23 and a bevel gear 24, a rotating gear 25 and an output gear 26 arranged in the gear box 23, as shown in FIG. Figure 10As shown, the central axis of the bevel gear 24 is the input shaft 21.
