Abstract
Description
Technical Field
[0001] This utility model relates to the field of spray gun technology, and in particular to a switch structure for spray guns. Background Technology
[0002] A spray gun is a device that uses the rapid release of liquid or compressed air as its power source. Spray guns are divided into two types: standard pressure and pressurized. When compressed air generated by an air compressor is ejected through the air cap at the front of the spray gun, a low-pressure zone lower than atmospheric pressure is created in front of the connected paint nozzle. This pressure difference at the spray gun nozzle draws paint from the paint tank and, under the action of the high-speed jet of compressed air, atomizes it into microparticles and sprays it onto the surface of the object being coated.
[0003] The spray gun requires power to operate normally. In the existing technology, the spray gun switch is located on one side. Therefore, when the user's dominant hand is opposite to the hand designed to hold the spray gun, it will be very inconvenient to turn the spray gun on and off. As a result, the user has to repeatedly flip the spray gun when using or turning it off, which affects the convenience of use. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a switch structure for a spray gun, the specific technical solution of which is as follows:
[0005] A switch structure for a spray gun includes a housing, a control switch, and a switch control key. The control switch is disposed within the housing, and a switch limiting groove is provided on the inner side wall of the housing. The switch control key is slidably disposed on the switch limiting groove and slides laterally within the switch limiting groove. A trigger block is provided on the switch control key, and the trigger block is located at the side end of the control switch. Pushing the switch control key causes the trigger block to press the control switch. Switch slots are provided on both sides of the housing near the switch control key. A toggle member is provided on both sides of the control switch, extending from the switch slots on both sides of the housing. An elastic component is provided on the side end of the switch control key. An open limiting hole and a close limiting hole are provided in the switch limiting groove, and the elastic component is embedded in the open limiting hole or the close limiting hole. Pushing the switch control key causes the elastic component to switch between the open limiting hole and the close limiting hole.
[0006] In some embodiments, a wave-shaped panel is provided at the toggle member, and the wave-shaped panel is located inside the switch slot.
[0007] In some embodiments, the side of the wave panel facing the switch slot is provided with a switch mark.
[0008] In some embodiments, the elastic component includes a reset spring and an elastic top block. The switch control key is provided with a cylindrical mounting groove. The reset spring is disposed in the cylindrical mounting groove. The elastic top block is slidably disposed on the outer side of the cylindrical mounting groove. The reset spring pushes the elastic top block outward. The elastic top block is engaged with the open limit hole and / or the closed limit hole.
[0009] In some embodiments, the elastic top block is spherically shaped on the side near the open limiting hole and / or the closed limiting hole.
[0010] In some embodiments, two elastic components are provided, and the two elastic components are symmetrically arranged on both sides of the switch control key. Two opening limit holes and two closing limit holes are provided, and the two opening limit holes and two closing limit holes are symmetrically arranged on both sides inside the housing. The elastic top blocks in the elastic components on both sides are respectively embedded in the opening limit holes or closing limit holes on both sides.
[0011] In some embodiments, the inner sidewall of the housing is symmetrically provided with switch limit grooves.
[0012] In some embodiments, a padding protrusion is provided at the front and rear ends of both sides of the switch control key, and the two padding protrusions on both sides respectively contact the switch limiting grooves on both sides.
[0013] In some embodiments, the upper and lower ends of the padding protrusion protrude in the upward and downward directions, respectively, and the upper and lower ends of the padding protrusion contact the upper and lower parts of the inner side of the corresponding switch limiting groove.
[0014] In some embodiments, a triangular reinforcing rib is provided between the trigger block and the housing.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] Firstly, in this design, toggle components are provided on both sides of the control switch. The toggle components extend from the switch slots on both sides of the housing, which makes it convenient for the user to toggle the switch control key to control the on / off switch of the spray gun when holding the housing. The user can hold the housing with either hand and operate the toggle components.
[0017] Secondly, this solution features a wave-shaped panel at the toggle point, located inside the switch slot. This panel effectively separates the switch slot, preventing external particles or moisture from entering the housing and causing the spray gun to jam or short-circuit, thus extending its lifespan. Furthermore, a switch indicator is provided on the side of the wave-shaped panel facing the switch slot, allowing operators to easily observe and assess the current status of the spray gun, thereby improving its usability.

[0032] like Figures 1 to 6As shown, a switch structure for a spray gun includes a housing 1, a control switch 2, and a switch control key 3. The control switch 2 is disposed inside the housing 1. A switch limiting groove 11 is provided on the inner side wall of the housing 1. The switch control key 3 is slidably disposed on the switch limiting groove 11 and slides laterally within the switch limiting groove 11. A trigger block 4 is provided on the switch control key 3. The trigger block 4 is located at the side end of the control switch 2. Pushing the switch control key 3 causes the trigger block 4 to press the control switch 2. Switch slots 12 are provided on both sides of the housing 1 near the switch control key 3. A toggle member 5 is provided on both sides of the control switch 2. The toggle members 5 extend from the switch slots 12 on both sides of the housing 1. This design allows the user to easily control the on / off state of the spray gun by toggling the switch control key 3 while holding the housing 1. The switch control key 3 has an elastic component 6 on its side. The switch limiting groove 11 has an opening limiting hole 13 and a closing limiting hole 14. The elastic component 6 is embedded in the opening limiting hole 13 or the closing limiting hole 14. Pushing the switch control key 3 causes the elastic component 6 to switch between the opening limiting hole 13 and the closing limiting hole 14. The positions of the opening limiting hole 13 and the closing limiting hole 14 correspond to the switch positions on the switch control key 3 and the contact switch, respectively. When the switch control key 3 is embedded in the opening limiting hole 13, the control switch 2 is in an on state. When the switch control key 3 is embedded in the closing limiting hole 14, the control switch 2 is in an off state.
[0033] The control switch 2 in this solution is a contact switch in the prior art. A contact arm is provided on one side of the contact switch. The contact switch is connected to the power supply line of the spray gun. By toggling the switch control key 3, the contact arm on the contact switch can be pushed, thereby realizing the adjustment of the spray gun's on / off state.
[0034] In some embodiments, a wave panel 51 is provided at the toggle member 5. The wave panel 51 is located inside the switch slot 12. The wave panel 51 can separate the switch slot 12, thereby preventing external particles or moisture from entering the housing 1 through the switch slot 12 and causing the spray gun to jam and short-circuit, thus improving the service life of the spray gun. In addition, a switch indicator is provided on the side of the wave panel 51 facing the switch slot 12. The switch indicator makes it easy for the operator to observe and judge the current status of the spray gun, improving the ease of use of the spray gun.
[0035] In some embodiments, the elastic component 6 includes a return spring 61 and an elastic top block 62. The switch control key 3 is provided with a cylindrical mounting groove. The return spring 61 is disposed in the cylindrical mounting groove. The elastic top block 62 is slidably disposed on the outer side of the cylindrical mounting groove. The return spring 61 pushes the elastic top block 62 outward. The elastic top block 62 is engaged with the open limiting hole 13 and / or the closed limiting hole 14.
[0036] Based on this, the elastic top block 62 is spherically shaped on the side near the open limiting hole 13 and / or the closed limiting hole 14, which facilitates the smooth movement of the elastic top block 62 when the elastic component 6 is adjusted in the open limiting hole 13 and the closed limiting hole 14.
[0037] In some embodiments, two elastic components 6 are provided, and the two elastic components 6 are symmetrically arranged on both sides of the switch control key 3. Two opening limit holes 13 and two closing limit holes 14 are provided, and the two opening limit holes 13 and two closing limit holes 14 are symmetrically arranged on both sides inside the housing 1. The elastic top blocks 62 in the elastic components 6 on both sides are respectively embedded in the opening limit holes 13 or closing limit holes 14 on both sides, thereby improving the structural stability of the switch control key 3 during adjustment.
[0038] In some embodiments, the inner sidewall of the housing 1 is symmetrically provided with switch limiting grooves 11, which can improve the structural stability of the switch control key 3 during adjustment.
[0039] Based on this, a padding protrusion 31 is provided at the front and rear ends of both sides of the switch control key 3. The two padding protrusions 31 on both sides contact the switch limiting slide grooves 11 on both sides respectively. The upper and lower ends of the padding protrusions 31 protrude in the upward and downward directions respectively. The upper and lower ends of the padding protrusions 31 contact the upper and lower parts of the inner side of the corresponding switch limiting slide grooves 11 respectively. By setting the side ends of the padding protrusions 31 and their upper and lower protrusions to contact the switch limiting slide grooves 11, the contact area between the switch control key 3 and the switch limiting slide grooves 11 is reduced. On this basis, the resistance of the switch control key 3 during sliding adjustment can be reduced, making it easier to use and improving the smoothness and stability when toggling the switch control key 3.
[0040] In some embodiments, a triangular reinforcing rib 7 is provided between the trigger block 4 and the housing 1. The reinforcing rib 7 can increase the structural strength of the trigger block 4 and prevent the deformation of the trigger block 4 from affecting the trigger sensitivity of the control switch 2.
[0041] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
