[0002] As a portable fastening tool, nail guns are widely used in the construction, manufacturing, mining and other fields. According to the "China Nail Industry Development Status Survey and Investment Trend Forecast Report (2022-2029)" released by Guanyan Report Network, the global nail fastening tool market size has been in a state of continuous growth in recent years, and the application areas of nail guns are also expanding.

[0003] According to different working principles, the commonly used nail guns on the market can be divided into four types: pneumatic nail guns, electric nail guns, gas-powered nail guns, and fuel-powered nail guns. Although these four types of nail guns have been widely used in actual production and life, they still have various shortcomings due to the limitations of their working principles. For example, pneumatic nail guns have the disadvantages of being loud and inconvenient to carry because they require an air pump to provide power; electric nail guns have the disadvantages of low nailing force and limited application scenarios; gas nail guns have the disadvantages of being large in size, high in price, complex in structure, and prone to the risk of gas explosions; fuel-powered nail guns are easily limited by gunpowder fuel, have the disadvantages of expensive consumables and low cost-effectiveness, and because they work on principles similar to guns, there is a risk of being modified into guns.

[0004] Therefore, the existing technology needs to be improved. Summary of the Invention

[0005] The present invention aims to provide a nail gun and nailing method based on the hydraulic-electric impact effect. This method can address the problems of low nailing force in electric nail guns and the high noise and portability of traditional pneumatic nail guns. Furthermore, the electricity consumed by the present invention is inexpensive and widely available, thus avoiding the expensive consumables of traditional fuel nail guns. Furthermore, the present invention's simple power structure and electrical energy consumption overcome the complex structure of gas-powered nail guns while also avoiding the risk of gas explosions. This invention provides a convenient, low-cost, and environmentally friendly nailing tool.

[0006] The present invention is achieved through the following technical solutions: In a first aspect, the present invention provides a nail gun based on the liquid-electric impact effect, which comprises Nail gun body: The front end of the nail gun body is provided with a gun head, the gun head is connected to a nail magazine for feeding nails, and the interior of the nail gun body is provided with a power chamber, and the power chamber stores liquid; Firing mechanism: The firing mechanism includes a piston that seals the liquid in the power chamber, and a firing pin is provided on the side of the piston close to the gun head, and the firing pin is aligned with the gun head; Discharge mechanism: The discharge mechanism includes a battery, and the battery is electrically connected to a discharge electrode 1 and a discharge electrode 2 extending into the power chamber.

[0024] Example 1 Combine Figure 1 and Figure 2 The figure shows a nail gun based on the liquid-electric impact effect according to embodiment 1 of the present invention, and the specific structure is described as follows.

[0025] The hydraulic-electric impact-based nail gun of this embodiment primarily comprises a main body 1, a firing mechanism 3, and a discharge mechanism 4. The main body 1 is constructed from a mixture of high-strength engineering plastic and metal alloy, offering excellent strength and grip. It is also protected by an insulating outer layer. The front end of the main body 1 includes a gun head 101. The central portion of the main body 1 is tubular, housing a power chamber 102. The rear end of the main body 1 includes a handle 103.

[0026] Furthermore, the bottom of the front end gun head 101 of the nail gun based on the hydraulic impact effect is connected to the nail magazine 2. The nail magazine 2 is a standard nail magazine 2 in the prior art, which can accommodate 20-30 standard nails. Under the action of the internal spring, the nail magazine 2 continuously feeds nails into the gun head 101.

[0027] The power chamber 102 inside the nail gun body 1 is cylindrical, and the chamber volume is about 50ml, and water is stored inside as the working fluid. A retaining ring 5 is fixed on the left side inside the power chamber 102, and the firing pin 302 passes through the center of the retaining ring 5.

[0028] In this embodiment, combined with Figure 2 and Figure 3 As shown, the firing mechanism 3 primarily comprises a piston 301 and a firing pin 302. The piston 301 is a metal disc, with the right end of the firing pin 302 fixedly connected to the center of the left end face of the piston 301. The edge of the piston 301 is provided with multiple notches 303, evenly distributed around the firing pin 302. The piston 301 divides the power chamber 102 into left and right sections, each of which is filled with liquid, filling approximately 80% of its volume.

[0029] Combine Figure 2 and Figure 3 As shown, the firing pin 302 is made of high-hardness alloy steel, with a conical head that precisely aligns with the nail-firing channel of the gun head 101. The firing pin 302 is sheathed with a return spring 6 made of stainless spring steel. The right end of the return spring 6 abuts the piston 301, and the left end is connected to the retaining ring 5, providing a return force for the firing pin 302.

[0030] Combine Figure 2 As shown, a horn cavity 8 is provided in the nail gun body 1. The large end of the horn cavity 8 is closer to the power chamber 102, and the small end is connected to a guide tube 801 aligned with the gun head 101. To prevent liquid leakage, two sealing rings are provided in the horn cavity 8. The sealing rings prevent liquid leakage, and the firing pin 302 can still reciprocate.

[0031] It should be noted that the guide tube 801 is made of a smooth metal tube with a polished inner wall, which can reduce the friction resistance of the firing pin 302 during its movement.

[0032] In this embodiment, the battery 403 of the discharge mechanism 4 is a rechargeable lithium battery with a capacity ranging from 5000mAh to 8000mAh. The battery 403 is installed in a battery compartment within the handle 103 of the nail gun body 1 and is connected to an external circuit via contacts. A capacitor 404 is a high-voltage energy storage capacitor installed at the rear of the nail gun body 1. A voltage sensor 405 is installed to the right of the capacitor 404. The capacitor 404 and the voltage sensor 405 are connected to each other to monitor the voltage of the capacitor 404 in real time. The voltage sensor 405 is also provided with a charging cable 4051 connected to the battery 403.

[0033] Combine Figure 2 As shown, the tail of discharge electrode 1 401 is connected to capacitor 404, and the heads of discharge electrode 1 401 and discharge electrode 2 402 extend into the interior of the power chamber 102 through the right end partition of the power chamber 102. Discharge electrode 1 401 is provided with a discharge portion 1 extending toward discharge electrode 2 402, and discharge electrode 2 402 is provided with a discharge portion 2 extending toward discharge electrode 1 401. Discharge portions 1 and 2 are conical and close to each other, with a spacing of 1.5 mm to 3 mm between the two discharge portions.

[0034] Furthermore, the contact switch 406 is provided at the handle 103 of the nail gun body 1 for user convenience. One end of the contact switch 406 is provided with a discharge line 1 4061 connected to the discharge electrode 1 401 , and the other end is provided with a discharge line 2 4062 connected to the capacitor 404 .

[0035] In this embodiment, combined with Figure 2 and Figure 4As shown, a safety valve 7 is installed at the top of the nail gun body 1. The safety valve 7 primarily comprises an adjustment tube 701 and a docking tube 704. The outer fixing sleeve of the docking tube 704 is provided with a connecting flange 7041. A hole is provided at the top of the nail gun body 1, through which the docking tube 704 is inserted and threadedly connected. The top end of the docking tube 704 is inserted into the adjustment tube 701, and the bottom end of the adjustment tube 701 is connected to the upper surface of the connecting flange 7041. A buffer plate 703 and a buffer spring 702 are installed within the adjustment tube 701. The buffer spring 702 is connected to the top surface of the buffer plate 703, and the bottom end of the buffer plate 703 blocks the top end of the docking tube 704. The buffer plate 703 is a circular metal plate with a diameter that matches the inner diameter of the adjustment tube 701. The buffer plate 703 is provided with a downward-facing circular sleeve 7031, which prevents the buffer plate 703 and buffer spring 702 from deflecting during movement.

[0036] Example 2 The present invention also provides a nail-shooting method. When the firing pin 302 is in the initial position, the battery 403 charges the capacitor 404 via the charging cable 4051, and the voltage sensor 405 detects the voltage on the capacitor 404 in real time. When the detected voltage reaches a specified value, the voltage sensor 405 turns on the electrical signal switch it controls, ensuring that the start electrical signal provided by the user through pressing or other means is transmitted to the contact switch 406. The voltage sensor 405 also provides a prompt through a sound (buzzer) or a light (indicator). After receiving the prompt, the user presses or other means to provide a start electrical signal. After receiving the start electrical signal, the contact switch 406 controls the discharge line 1 4061 and the discharge line 2 4062 to conduct. After conduction, the electrical energy stored in the capacitor 404 is instantly transmitted to the discharge electrode 1 401 and the discharge electrode 2 402. The two electrodes discharge instantly, causing the surrounding liquid to rapidly vaporize and expand, generating a high-pressure impact force, which is instantly transmitted to the piston 301, pushing the piston 301 and the firing pin 302 forward rapidly, completing the nail shooting. After the nail shooting is completed, under the action of the return spring 6, the firing pin 302 and the piston 301 return to the initial position and wait for the next nail shooting operation.

[0037] In summary, the present invention provides a nail gun based on the liquid-electric impact effect, including a nail gun body 1: a gun head 101 is provided at the front end of the nail gun body 1, and the gun head 101 is connected to a nail magazine 2 for feeding nails, and a power chamber 102 is provided inside the nail gun body 1, and liquid is stored in the power chamber 102; a firing mechanism 3: the firing mechanism 3 includes a piston 301 for sealing the liquid in the power chamber 102, and a firing pin 302 is provided on the side of the piston 301 close to the gun head 101, and the firing pin 302 is aligned with the gun head 101; a discharge mechanism 4: the discharge mechanism 4 includes a battery 403, and the battery 403 is electrically connected to a discharge electrode 1 401 and a discharge electrode 2 402 extending into the power chamber 102. After the discharge electrodes 1 401 and 402 are discharged, the liquid vaporization expansion caused by the liquid-electric effect generates an impact force, and then pushes the firing pin 302 into the gun head 101, and finally the firing pin 302 hits the nail to perform the nail shooting work. A retaining ring 5 is fixedly installed inside the power chamber 102, and a return spring 6 is provided on the outside of the firing pin 302.

[0038] The present invention also provides a nail shooting method, which uses a nail shooting gun based on the liquid-electric impact effect, and also includes the following method: when the firing pin 302 is in the initial position, the battery 403 charges the capacitor 404, and the voltage on the capacitor 404 is detected by the voltage sensor 405. After the detection voltage reaches the specified voltage value, the voltage sensor 405 turns on the electric signal switch it controls to ensure that the start electric signal given by the user by pressing or other methods can be transmitted to the contact switch 406.
