[0002] Liquid pumps are widely used in daily life, such as in bottled liquid products like kitchen degreasers, shampoos, cosmetics, perfumes, and insect repellents. Liquid pump technology is more convenient, efficient, and allows for higher production volumes compared to traditional bottle opening methods. Spray guns are a common type of liquid pump tool, requiring a liquid container. They typically consist of a trigger, chamber, piston rod, and nozzle. Their working principle utilizes the internal pressure of the piston to increase the internal pressure of the liquid container, thus spraying liquid from the nozzle. Existing spray gun triggers require a metal spring for reset, which is prone to rusting, affecting usability, and also hinders recycling. Summary of the Invention

[0027] Combination Figures 1-6 As shown, this application provides a fine mist spray gun, including a pump body 1, a nozzle 2, and a trigger 3. The nozzle 2 and the pump body 1 are connected by a hollow piston rod 4. The end of the piston rod 4 is integrally formed with a liquid outlet pipe 14, which connects to the inside of the nozzle 2, thereby forming a liquid outlet channel. The trigger 3 is connected to the piston rod 4 through a reset mechanism. The reset mechanism includes a drive member 5 and an elastic member 6. One end of the elastic member 6 is inserted into the drive member 5, and the other end abuts against the pump body 1. The piston rod 4 is located below the drive member 5. The drive member 5 and the trigger 3 are respectively hinged to the pump body 1. In this embodiment, the trigger 3 is hinged to the side of the pump body 1 located at the nozzle 2, the drive member 5 is hinged to the middle position of the pump body 1, and the trigger 3 is located to one side of the drive member 5. Pressing the trigger 3 can push the drive member 5, which presses down the piston rod 4 to make it move and dispense liquid. At this time, the elastic member 6 is compressed, thereby generating elastic force. After releasing the trigger 3, the elastic member 6 can drive the drive member 5 and the trigger 3 to reset.

[0028] In some embodiments, such as Figures 1-4 As shown, the driving member 5 is symmetrically provided with an inclined first driving surface 7, and the trigger 3 is symmetrically provided with an inclined second driving surface 8. The second driving surface 8 is in contact with the first driving surface 7. When the trigger 3 is pressed, the first driving surface 7 is pushed to one side through the second driving surface 8, causing the driving member 5 to flip along the hinge point. The driving member 5 is provided with a hinge seat 13, and the end of the piston rod 4 is installed in the hinge seat 13. When the driving member 5 flips, the first driving surface 7 rises and the hinge seat 13 falls, thereby pressing down the piston rod 4 to discharge liquid. In this embodiment, the elastic member 6 is C-shaped. The drive component 5 passes through the elastic component 6. One end of the drive component 5 is symmetrically provided with hooks 9. The upper end of the elastic component 6 is provided with a support rod 10, which is inserted into the hook 9. Therefore, when the drive component 5 is flipped by the pressure of the trigger 3, it will pull the support rod 10 at one end to compress the elastic component 6, thereby generating elastic force. The lower end of the elastic component 6 is provided with a support rib 11. The pump body 1 is provided with a fixing groove 12. The support rib 11 is inserted into the fixing groove 12. The support rib 11 is inserted into the fixing groove 12, which restricts the lower end of the elastic component 6 to achieve the effect of generating elastic force.

[0029] In some embodiments, such as Figure 5 and Figure 6As shown, a one-way valve 15 is installed between the nozzle 2 and the outlet pipe 14. The one-way valve 15 can prevent external air from entering the outlet pipe 14. An atomizing plate 16 is installed at the end of the nozzle 2 to atomize the sprayed liquid. A piston 17 is connected to the bottom of the piston rod 4. The piston 17 is movably disposed in the pump body 1. An outlet seat 18 is provided in the piston 17. The outlet seat 18 connects the pump body 1 and the piston rod 4. Openings are provided on both sides of the outlet seat 18. Liquid in the pump body 1 enters the outlet seat 18 through the openings. Inside the liquid outlet 18, a spring 19 and a sealing tube 20 are installed. Both the upper and lower ends of the sealing tube 20 are provided with sealing stop surfaces. The spring 19 pushes the sealing tube 20 to seal the piston rod 4 through the stop surfaces. Under normal conditions, the sealing tube 20 seals the piston rod 4. When the liquid in the liquid outlet 18 accumulates, it will press down on the stop surfaces to make the sealing tube 20 disengage from the liquid inlet of the piston rod 4 to unlock it. In this embodiment, an umbrella valve 21 is installed at the bottom of the pump body 1. The umbrella valve 21 is connected to the external bottle body to achieve a one-way sealing effect.
