[0025] Example

[0026] Reference Figure 1-6 As shown, this utility model discloses a wireless electric spray gun structure with a detachable lithium battery 202, including a spray gun body 10 and a battery pack 20. The spray gun body 10 has a U-shaped frame 101 at the bottom of the handle. The upper bottom of the frame 101 is provided with a limiting plate 102, a sliding step 103 and an electrical connection plate 104. The limiting plate 102 is located at one end of the upper bottom of the frame 101, and the sliding step 103 is located on both sides of the upper bottom of the frame 101. The sliding step 103 is used to support the battery pack 20 when it is installed and prevent vertical movement. The limiting plate 102 is used to restrict the horizontal forward and backward movement of the battery pack 20. The electrical connection plate 104 is used to electrically connect the battery pack 20.

[0027] Reference Figure 1-6 As shown, the battery pack 20 includes a housing 201, a battery 202, and a control circuit board 203. The battery 202 and the control circuit board 203 are disposed inside the housing 201. The battery 202 is electrically connected to the control circuit board 203. An elastic block 204 is installed at one end of the housing 201 through an elastic element. In this embodiment, the elastic element is a spring. Under normal conditions, the spring pushes the elastic block 204 upward to extend it out of the housing 201. Guide grooves 205 are opened on both sides of the housing 201 along the length direction. An electrical connection plug 104 is electrically connected to the circuit control board. Specifically, the housing 201 has several slots 206. Battery cards 2031 are positioned on both sides of each slot 206. The battery cards 2031 are electrically connected to the control circuit board 203. During use, the guide groove 205 is aligned with the sliding step 103 of the frame 101 and inserted into the frame 101. When pushed into place, the electrical connection plate 104 is inserted into the slot 206. The battery cards 2031 on both sides of the slot 206 abut against the electrical connection plate 104. The electrical connection plate 104 is electrically connected to the battery 202, enabling the battery 202 to supply power to the spray gun body 10. After the battery pack 20 is installed in place, the elastic locking block 204 abuts against the limiting plate 102 to prevent the battery pack 20 from retracting.

[0028] Reference Figure 1-7 As shown, the battery pack 20 includes an elastic locking block 204. Specifically, a spring is installed at the bottom of the elastic locking block 204, and one side of the locking block extends to form a pressing surface 2041. The pressing surface 2041 is provided with anti-slip stripes. When the battery pack 20 needs to be removed, the elastic locking block 204 is pressed down into the housing 201, and the battery pack 20 can be pulled out from the frame 101. Furthermore, one side of the locking block is an inclined surface, and the other side is a vertical surface. When the battery pack 20 is inserted into the frame 101, the inclined surface of the locking block abuts against the limiting plate 102, and the limiting plate 102 presses down on the elastic locking block 204 along the inclined surface. When it is fully in place, the vertical surface of the elastic locking block 204 abuts against the limiting plate 102, which serves to restrict the battery pack 20 from exiting.

[0029] In addition, notches 105 are further opened on both sides of the frame 101. The notches 105 are beneficial for heat dissipation and make it easier for users to observe the usage of the battery pack 20.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
