[0013] Furthermore, a spray nozzle is provided at one end of the gun body.

[0014] Compared with the prior art, this utility model provides a lithium-ion battery brushed spray gun, which has the following beneficial effects:

[0015] This lithium-ion brushed spray gun powers the main unit with a removable battery installed at the bottom of the handle. It is not limited by the length of the power cord or the need for direct connection to AC power, making it more convenient to carry and allowing for unrestricted operation. Users only need to prepare a few battery packs to meet the battery life requirements. The battery pack and handle are locked together with a snap-fit ​​mechanism, making the assembly more stable.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model discloses a lithium-ion battery brushed spray gun, including a main unit 1. A gun body 2 is provided at one end of the main unit 1. A material tank 3 is detachably connected to the bottom of the gun body 2. A DC motor 12 is provided inside the main unit 1. A handle 11 is provided at the bottom of the main unit 1. A foot plate 111 is provided at the bottom of the handle 11. A battery pack 4 is movably connected to the bottom of the foot plate 111 through a pin 14. A battery 41 is provided inside the battery pack 4 for powering the DC motor 12. The DC motor 12 is a brushed motor, which has a significant cost advantage compared to a brushless motor.

[0023] Specifically, the bottom of the foot plate 111 is provided with a pin 14 that is electrically connected to the battery 41. When the battery pack 4 is snapped into place with the bottom of the foot plate 111, the pin 14 is inserted into the inside of the battery pack 4 and connected to the conductive copper sheet on the battery 41 to complete the conductive connection.

[0024] Specifically, the bottom of the foot plate 111 is provided with a slot 15 located on one side of the plug 14, and the top of the battery pack 4 is provided with a button 42. One end of the button 42 is provided with a buckle 43 that is movably engaged with the slot 15. A spring is provided at the bottom of the button 42. When the button 42 is pressed, the button 42 drives the buckle 43 to disengage from the slot 15, so the battery pack 4 can be pulled out horizontally. One side of the buckle 43 is inclined. When the battery pack 4 is connected to the bottom of the handle 11, there is no need to press the button 42. The buckle 43 will automatically press down to avoid contact with the bottom of the handle 11. When the buckle 43 is aligned with the slot 15, the spring rebounds and pushes the buckle 43 into the inside of the slot 15. The battery pack 4 and the bottom of the handle 11 are connected by a movable plug-in method and locked by the buckle 43, which ensures the connection stability between the battery pack 4 and the handle 11.

[0025] Specifically, the handle 11 is equipped with a micro switch 13 and a switch spring push rod 16 for driving the micro switch 13. When the user pulls the trigger 23, the trigger 23 abuts against the switch spring push rod 16 to trigger the micro switch 13, thereby realizing the control of the DC motor 12.

[0026] Specifically, the top of the material barrel 3 is threadedly connected to the bottom of the gun body 2, and the material barrel 3 can be removed and replaced by rotating it.

[0027] Specifically, the gun body 2 is also equipped with a suction pipe 22 extending into the material barrel 3. One end of the gun body 2 is equipped with a spray head 25. When the DC motor 12 is started, some air enters the material barrel 3, causing the liquid inside the material barrel 3 to be pressurized and enter the area around the adjusting rod 21 through the suction pipe 22. When the user pulls the trigger 23, the trigger 23 drives the adjusting rod 21 to move backward, causing the liquid to spray out through the gap created by the retraction of the adjusting rod 21. The air inside the gun body 2 disperses the liquid into atomized spray through the spray head 25.

[0028] Specifically, the gun body 2 is externally hinged with a trigger 23 for driving the adjusting rod 21 and the switch spring push rod 16.

[0029] Specifically, a stroke adjustment knob 24 is provided on one side of the trigger 23. Rotating the stroke adjustment knob 24 can control the pulling distance of the trigger 23, thereby adjusting the stroke of the adjustment rod 21 and adjusting the liquid spray volume.

[0030] In summary, this lithium-ion brushed spray gun powers the main unit 1 by installing a removable battery 41 at the bottom of the handle 11. It is not limited by the length of the power cord or the need for direct connection to AC power, making it more convenient to carry and allowing for unrestricted operation. Users only need to prepare a few battery packs 4 to meet the battery life requirements. The battery packs 4 and the handle 11 are locked together by buckles 43, making the assembly more stable. The structure is simple and compact, which is economical and has broad application prospects.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
