[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1 to 4 The illustrated paint spraying device for decorative and finishing projects includes a paint spray gun 2, with a base 1 fixedly mounted at the bottom of the spray gun 2. A gun barrel 8, an air inlet pipe 3, and a bracket 4 are fixedly mounted on the paint spray gun 2. A spray bottle 5 is fixedly mounted on the bracket 4, and the spray bottle 5 is fixedly connected to the gun barrel 8. A stirring mechanism 7 is installed inside the spray bottle 5, and a feed pipe 6 is connected to and fixedly mounted on the spray bottle 5. A trigger 15 is mounted on the paint spray gun 2 to control the paint spraying. All of the above are prior art and are no different from existing equipment, and will not be described in detail here.

[0025] The trigger 15 is installed below the barrel 8, and the end of the barrel 8 is connected to and fixed to the nozzle 9.

[0026] A guide rail 16 is fixedly installed at the bottom of the barrel 8 along the axial direction of the barrel 8. The cross-section of the guide rail 16 is inverted T-shaped. A matching slider 13 is slidably sleeved on the guide rail 16. Two support rods 12 are fixedly installed at the end of the slider 13 near the nozzle 9 along the axial direction of the barrel 8, and the slider 13 is located between the two support rods 12.

[0027] The ends of the two support rods 12 away from the slider 13 are rotatably engaged with a hopper 10 for collecting paint liquid.

[0028] Specifically, both support rods 12 are elastic rods. Two coaxially opposed rotating shafts are fixed on the hopper 10, with each shaft corresponding to one of the two support rods 12. Each shaft passes through and rotates with its corresponding support rod 12. That is, by swinging the two support rods 12, the two rotating shafts on the hopper 10 can disengage from their respective support rods 12.

[0029] The slider 13 is engaged with the trigger 15 via a transmission component that drives the slider 13 to slide axially along the barrel 8.

[0030] Specifically, the transmission component includes a push rod 14; one end of the push rod 14 is hinged to the movable end of the trigger 15 away from the paint spray gun 2, and the other end is hinged to the slider 13. To prevent fingers from being pinched, the push rod 14 can be an arc-shaped rod that matches the trigger 15.

[0031] A counterweight 11 is detachably mounted on the bottom of the hopper 10 via a magnet. The counterweight 11 is used to ensure that the opening of the hopper 10 always faces upward.

[0032] Working principle: In the initial state, when the trigger 15 is released, the hopper 10 is directly below the nozzle 9. The counterweight 11 installed at the bottom of the hopper 10 through the magnet generates downward gravity. Combined with the rotation of the coaxially opposed rotating shaft on the hopper 10 and the two elastic rod support rods 12, the opening of the hopper 10 is always facing upward, ready to collect the paint liquid remaining at the nozzle 9 at any time.

[0033] When spraying is required, the operator pulls the trigger 15. The movable end of the trigger 15 away from the paint spray gun 2 pulls the slider 13 through the push rod 14. Since the slider 13 is slidably fitted with the inverted T-shaped guide rail 16, the slider 13 slides smoothly along the guide rail 16. The slider 13 simultaneously drives the two support rods 12 fixed on it and the hopper 10 rotatably engaged with the support rods 12 to move together, so that the hopper 10 is completely removed from under the nozzle 9. At this time, the paint is atomized and sprayed out from the nozzle 9 through the gun barrel 8, realizing normal spraying operation.

[0034] After the spraying operation is completed, the operator releases trigger 15. Trigger 15 returns to its initial position under its own restoring force. Push rod 14 then pushes slider 13 in the opposite direction, causing it to slide along guide rail 16. Slider 13 drives support rod 12 and hopper 10 to return to their original positions along the gun barrel 8. Finally, hopper 10 returns to directly below nozzle 9. During this process, counterweight 11 continuously acts to ensure that hopper 10 remains open and facing upwards during both movement and reset, efficiently collecting residual paint drips from nozzle 9 and preventing paint contamination of decorative panels or the construction environment.

[0035] When it is necessary to clean or replace the hopper 10, the elastic properties of the support rod 12 can be used to push the two support rods 12 to the sides, so that the rotating shaft on the hopper 10 can be disengaged from the support rods 12, and the hopper 10 can be removed. If it is necessary to replace the counterweight 11, it can be quickly disassembled and assembled through the detachable connection characteristics of the magnet, making the operation convenient.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
