[0024] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0025] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figure 1 As shown, a handheld spray gun includes a handle 100, a charging base 200 at the bottom of the handle 100, and a connecting seat 210 at the top of the charging base 200. The handle 100 is assembled from a first connecting member 110 and a second connecting member 120, which are clamped on both sides of the connecting seat 210. A support platform 130 is provided at the top of the handle 100, and a spray painting assembly 300 is mounted on the top of the support platform 130. A button 140 for controlling the spray painting assembly 300 is provided on the side wall of the handle 100.

[0026] In the normal state of this application, the grip 100 is divided into a first connector 110 and a second connector 120. After they are installed on both sides of the connector 210, the first connector 110 and the second connector 120 are connected to each other, thereby clamping and fixing the grip 100 and the charging base 200 together. When painting is required, the painting assembly 300 is activated by operating the button 140 on the grip 100 to achieve the painting function of the product.

[0027] Compared with the prior art, the grip 100 of this application clamps the charging base 200 through the first connector 110 and the second connector 120. When it is necessary to replace the charging base 200 with a different label, it is only necessary to remove the first connector 110 and the second connector 120 from the connector 210. While ensuring the reliability of the connection between the grip 100 and the charging base 200, it can also be adapted to different types of charging bases 200, and has a wider range of versatility.

[0028] Furthermore, based on the above embodiments, such as Figure 2As shown, the connecting seat 210 is provided with a first through hole 211. The first through hole 211 is disposed opposite to each other on the side wall of the connecting seat 210. A hollow first connecting rod 111 and a hollow second connecting rod 121 are provided on the bottom inner side of the first connecting member 110 and the second connecting member 120. The first connecting rod 111 can be inserted into the second connecting rod 121. When the first connecting member 110 and the second connecting member 120 are connected to the charging base 200, the first connecting rod 111 and the second connecting rod 121 are inserted from both sides of the first through hole 211 on the side wall of the connecting seat 210, and then they are sleeved and fixed to each other in the connecting seat 210. Finally, a screw (not shown in the figure) passes through the first connecting rod 111 and the second connecting rod 121 to fix them.

[0029] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 3 As shown, a receiving cavity 150 is provided inside the grip 100. The receiving cavity 150 is surrounded by a first connector 110 and a second connector 120. A compressed air tank 160 is provided inside the receiving cavity 150. An air outlet 161 is provided at the top of the compressed air tank 160. Several outlet support plates 162 are provided between the bottom of the compressed air tank 160 and the top of the connecting seat 210. The outlet support plates 162 provide vertical support for the compressed air tank 160 inside the grip 100. When the gas in the compressed air tank 160 is used up, it can be replaced by opening the connection between the first connector 110 and the second connector 120 and the connecting seat 210. In this way, the first connector 110 and the second connector 120 not only facilitate the replacement of the charging base 200, but also facilitate the replacement of the compressed air tank 160.

[0030] Furthermore, based on the above embodiments, such as Figure 3 As shown, a limiting ring 151 protrudes inward from the sidewall inside the first connector 110 and the second connector 120. When the compressed air tank 160 is located in the receiving cavity 150, the limiting ring 151 forms a tight contact with the sidewall of the compressed air tank 160. In this way, the limiting ring 151 provides support for the compressed air tank 160 in the lateral direction inside the handle 100, thereby preventing the compressed air tank 160 from shaking in the receiving cavity 150.

[0031] Furthermore, based on the above embodiments, such as Figure 3As shown, the paint spraying assembly 300 includes a spray chamber 310, with a nozzle 311 disposed at one end of the spray chamber 310. A connection port 312 is provided at the top of the spray chamber 310 for connecting a paint can (not shown in the figure). An air inlet 313 is provided at the bottom of the spray chamber 310, and the air inlet 313 is connected to an air outlet 161 via an air pipe (not shown in the figure). A needle valve 314 is disposed inside the spray chamber 310, with one end of the needle valve 314 rotating to seal inside the nozzle 311, and the other end connecting to the rotating nozzle. The motor 320 is connected. Under normal conditions, one end of the needle valve 314 is rotated and sealed on the nozzle 311. A paint can is installed on the connection port 312, and the paint enters the spray chamber 310. When painting is required, the rotary motor 320 is started by the button 140. The rotary motor 320 drives the needle valve 314 to rotate, and the needle valve 314 rotates out of the nozzle 311, so that it is no longer sealed on the nozzle 311. Then, compressed gas enters the spray chamber 310 through the air inlet 313 and sprays the paint in the spray paste out of the nozzle 311.

[0032] Furthermore, based on the above embodiments, such as Figure 3 As shown, a control circuit board 330 is provided at the bottom of the rotary motor 320. One side of the control circuit board 330 is electrically connected to the button 140, and the other side is provided with a battery 340. The battery 340 is electrically connected to the control circuit board 330 and the rotary motor 320. When the operator presses the button 140, the control circuit board 330 sends an electrical signal to the rotary motor 320, thereby starting the rotary motor 320 to drive the needle valve 314 to rotate. The specific principle is existing technology and will not be described in detail in this article.

[0033] Furthermore, based on the above embodiments, such as Figure 3 As shown, a heat dissipation grille 131 is provided inside the support platform 130, so that the heat generated by the battery 340 and the control circuit board 330 in the housing cavity 150 can be dissipated to the outside through the heat dissipation grille 131.

[0034] Furthermore, based on the above embodiments, such as Figure 2 As shown, a connecting plate 220 is provided at the bottom of the charging base 200, and the connecting plate 220 is electrically connected to the battery 340. When charging is required, first connect the charging base 200 to the grip assembly, then insert the charging base 200 into the battery 340 housing, and connect the connecting plate 220 to the battery 340 housing.

[0035] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
