A spray gun

Abstract

This utility model employs a spray gun, including a housing, a gas storage mechanism, a ignition mechanism, a sparking mechanism, a gas outlet mechanism, and a gas volume adjustment mechanism. The gas outlet mechanism includes a gas outlet adjustment end, and the gas volume adjustment mechanism includes a gas outlet push part and a longitudinal actuating part. The gas outlet push part and the gas outlet adjustment end are linked, and the gas outlet push part rotates coaxially with the longitudinal actuating part. When adjusting the gas volume of the spray gun, the operator can hold the spray gun housing and use the operator's fingertips to actuate longitudinally, thereby driving the longitudinal actuating part of the gas volume adjustment mechanism. Then, through the linkage between the gas outlet push part and the gas outlet adjustment end inside the spray gun, the adjustment of the gas outlet mechanism is achieved. Compared with existing methods, this avoids the situation where pushing or swinging the gas outlet mechanism directly laterally is difficult, resulting in difficult adjustment and inconvenient operation.

Description

Technical Field

[0001] This utility model relates to the field of lighter technology, and in particular to a spray gun. Background Technology

[0002] Lighters (also known as igniters, lighters, etc.) or blowtorches used in the market are common ignition devices. These devices usually involve a flame adjustment mechanism that can adjust the flame intensity. The structure of the flame adjustment mechanism currently used mostly includes annular teeth grooves distributed on the annular surface of the gas needle, and a lever with annular inner teeth grooves fitted on the gas needle. The annular teeth grooves are matched synchronously, so that when the lever moves, the gas output is adjusted through the meshing transmission between the annular teeth grooves, thereby adjusting the flame intensity of the subsequent ignition device.

[0003] Existing designs for the external structure of the actuating element commonly involve extending the actuating element outwards towards the ignition device to form an extension rod. Adjustment is achieved by pushing the actuating element to swing. Alternatively, the actuating element may be made larger, with a significant portion extending beyond the ignition device. The outer circumference of the actuating element may be formed with a toothed structure, allowing adjustment by the user's fingers or fingernails to rotate the actuating element. However, in practical use, it has been found that these existing actuating element structures often result in direct contact with the gas outlet needle, making it difficult and inconvenient for the operator to adjust the flame intensity. Summary of the Invention

[0004] In view of the above shortcomings, this utility model provides a spray gun that allows for convenient adjustment of the firepower.

[0005] To achieve the above objectives, this utility model employs a spray gun, including a housing, and a gas storage mechanism, a ignition mechanism, an sparking mechanism, and a gas outlet mechanism connected to the gas storage mechanism, all distributed within the housing. The sparking mechanism is used to ignite the gas exiting through the gas outlet mechanism, and the ignition mechanism is used for the flame to emerge from the spray gun. The spray gun also includes a gas volume adjustment mechanism distributed on one side of the gas outlet mechanism. The gas outlet mechanism includes a gas outlet adjustment end extending to the outside of the gas storage mechanism. The gas volume adjustment mechanism includes a gas outlet end pushing part extending to one side of the gas outlet adjustment end and a longitudinal actuating part extending to the outside of the housing. The gas outlet end pushing part and the gas outlet adjustment end are linked and cooperate, and the gas outlet end pushing part rotates coaxially with the longitudinal actuating part.

[0006] The air output adjustment mechanism allows the longitudinal actuation part to be moved longitudinally from the outside by a finger, and the air output end push part rotates coaxially with the longitudinal actuation part and works in conjunction with the air output adjustment end to adjust the air output of the spray gun and the firepower of the spray gun.

[0007] The present invention is further configured such that the air outlet pushing part and the air outlet adjusting part are staggered, and the intersecting areas of the two are connected by a bevel gear meshing connection.

[0008] The present invention is further configured such that the air volume adjustment mechanism includes a limiting part distributed between the longitudinal actuating part and the air outlet pushing part, and the limiting part forms a connection between the longitudinal actuating part and the air outlet pushing part. The housing includes a first housing and a second housing connected to the first housing in a splicing manner. The first and second housings are respectively provided with splicing grooves. By splicing the first and second housings, the splicing groove on the first housing and the splicing groove on the second housing are spliced ​​together to form an annular limiting groove for limiting the limiting part on the air volume adjustment mechanism.

[0009] The present invention is further configured such that the air outlet pushing part includes a transverse gear distributed in the direction of the air outlet adjusting end, a support part connected to the transverse gear, and a rotation limiting block distributed on the circumferential surface of the support part. The air outlet adjusting end includes a longitudinal gear distributed on the outer edge of the air outlet adjusting end. A support seat is formed in the housing on one side relative to the air outlet adjusting end. The support part is supported on the support seat and rotates circumferentially on the support seat. The rotation limiting block rotates against the support seat to form a rotation overtravel limit for the air outlet volume adjusting mechanism.

[0010] The air outlet pusher and the air outlet adjustment end are connected by a horizontal gear and a vertical gear, forming an air outlet volume adjustment mechanism to control the rotation adjustment action of the air outlet mechanism.

[0011] The present invention is further configured such that the outer peripheral surface of the longitudinal actuating part has a knurled surface structure.

[0012] The present invention is further configured such that the ignition mechanism includes a jumping plate abutting against the gas outlet mechanism, an electronic igniter with a drive end, a linkage member covering the drive end and whose bottom foot abuts against the jumping plate, and an ignition component limited on the housing. The ignition component includes an ignition drive part distributed outside the housing and an ignition linkage part extending into the housing and distributed on one side of the linkage member. The ignition drive part and the ignition linkage part are linked together. The spray gun drives the ignition drive part to generate driving force, which is transmitted to the ignition linkage part, thereby driving the electronic igniter. The bottom foot of the linkage member drives the jumping plate and constitutes the gas outlet drive for the gas outlet mechanism.

[0013] The present invention is further configured such that the ignition drive unit includes an outer drive unit, a connecting rod, and an inner extension rod arranged and connected in sequence; the ignition linkage unit includes a rotating disk and a drive rod connected to the rotating disk; the other end of the inner extension rod connected to the connecting rod extends into the housing; and the rotating disk is sleeved on the inner extension rod and rotates synchronously with the inner extension rod.

[0014] The present invention is further configured such that the spray gun also includes decorative parts distributed outside the housing. The decorative parts include a first gear component sleeved on the inner extension rod and rotating synchronously with the inner extension rod, a second gear component meshing with the first gear component, and a fixing component. The second gear component is sleeved on the fixing component and is limited to the housing by the fixing component.

[0015] The spray gun is driven by the external drive unit by the finger, and the force is transmitted sequentially between the connecting rod and the inner extension rod, forming a rotation through the inner extension rod, which in turn drives the first gear to rotate, and the component is used for meshing rotation between the first gear and the second gear.

[0016] The beneficial effects of this utility model are as follows: By simultaneously incorporating an air outlet pushing part and a longitudinal actuating part into the air outlet adjustment mechanism used for the spray gun, an air outlet adjustment end is also incorporated into the air outlet mechanism. The air outlet pushing part and the air outlet adjustment end are linked together. Furthermore, the air outlet pushing part of the air outlet adjustment mechanism can rotate coaxially with the longitudinal actuating part. Therefore, when adjusting the air outlet volume of the spray gun involved in this utility model, the operator can hold the spray gun housing and use the operator's fingertips to perform a longitudinal actuation, thereby driving the longitudinal actuating part of the air outlet adjustment mechanism. Then, through the linkage between the air outlet pushing part and the air outlet adjustment end inside the spray gun, the adjustment of the air outlet mechanism, compared to existing methods, avoids the difficulty of pushing or swaying when directly pushing the air outlet mechanism laterally, which would otherwise cause strain and inconvenience in adjustment.

[0029] like Figure 1-12 As shown, a specific embodiment of this utility model is a spray gun, including a housing 1, and a gas storage mechanism 7, a flame outlet mechanism 3, an ignition mechanism 2, and a gas outlet mechanism 5 connected to the gas storage mechanism 7 distributed within the housing 1. The ignition mechanism 2 is used to ignite the gas exiting through the gas outlet mechanism 5, and the flame exiting through the ignition mechanism 3 is used for the flame to emerge from the spray gun. The spray gun also includes a gas volume adjustment mechanism 4 distributed on one side of the gas outlet mechanism 5. The gas outlet mechanism 5 includes a gas outlet adjustment end 51 extending to the outside of the gas storage mechanism 7. The gas volume adjustment mechanism 4 includes a gas outlet end pushing part extending to one side of the gas outlet adjustment end 51 and a longitudinal actuating part 41 extending to the outside of the housing 1. The gas outlet end pushing part and the gas outlet adjustment end 51 are linked and cooperated, and the gas outlet end pushing part rotates coaxially with the longitudinal actuating part 41.

[0030] The air volume adjustment mechanism 4 allows the longitudinal actuation part 41 to be moved longitudinally from the outside by a finger, and the air outlet push part rotates coaxially with the longitudinal actuation part 41 and works in conjunction with the air outlet adjustment end 51 to adjust the air volume of the spray gun and the firepower of the spray gun. The outer peripheral surface of the longitudinal actuation part 41 has a knurled surface structure.

[0031] By incorporating an air volume adjustment mechanism 4 for the spray gun with an air outlet pusher and a longitudinal actuating part 41, and simultaneously incorporating an air outlet adjustment end 51 on the air outlet mechanism 5, the air outlet pusher and the air outlet adjustment end 51 are linked together. Furthermore, the air outlet pusher on the air volume adjustment mechanism 4 can rotate coaxially with the longitudinal actuating part 41. Thus, when the air volume of the spray gun is adjusted, the operator can hold the spray gun housing 1 and use the operator's fingertips to actuate the longitudinal actuating part 41 of the air volume adjustment mechanism 4. Then, through the linkage between the air outlet pusher and the air outlet adjustment end 51 inside the spray gun, the adjustment of the air outlet mechanism 5 is made easier than in the past. There is no difficulty in pushing or swinging when pushing the air outlet mechanism 5 laterally, which would cause difficulty in adjustment and inconvenience in operation. At the same time, the preferred solution for the outer peripheral surface of the longitudinal actuating part 41 is a knurled surface structure.

[0032] like Figure 3 , 4 As shown in Figures 8-10, the air outlet pusher and the air outlet adjustment end 51 are staggered, and the intersecting areas of the two are connected by a bevel gear meshing. Through the above, the air outlet pusher and the air outlet adjustment end 51 can reliably adjust the air volume of the air outlet mechanism 5 through meshing transmission, and at the same time ensure the reliability of the transmission between the air outlet mechanism 5 and the air volume adjustment mechanism 4.

[0033] like Figure 3 , 4 As shown in Figures 8-10, the air volume adjustment mechanism 4 also includes a limiting part 42 distributed between the longitudinal actuating part 41 and the air outlet pushing part. The limiting part 42 forms a connection between the longitudinal actuating part 41 and the air outlet pushing part. The housing 1 includes a first housing 11 and a second housing 12 connected to the first housing 11 in a splicing manner. The first and second housings are respectively provided with splicing grooves 10. By splicing the first and second housings, the splicing grooves 10 on the first housing 11 and the splicing grooves 10 on the second housing 12 are spliced ​​together, forming an annular limiting groove for limiting the limiting part 42 on the air volume adjustment mechanism 4. Through the above, when the air volume adjustment mechanism 4 is used on the spray gun, it can be reliably inserted and limited at the corresponding splicing groove 10 position on the housing 1.

[0034] like Figure 3-5As shown in Figures 8-10, the air outlet pusher includes a transverse gear 44 distributed in the direction of the air outlet adjustment end 51, a support part 43 connected to the transverse gear 44, and a rotation limit block distributed on the circumferential surface of the support part 43. The air outlet adjustment end 51 includes a longitudinal gear distributed on the outer edge of the air outlet adjustment end 51, and a support seat 6 is formed in the housing 1 on one side relative to the air outlet adjustment end 51. The support part 43 is supported on the support seat 6 and rotates circumferentially on the support seat 6. The rotation limit block rotates against the support seat 6 to form a rotation overtravel limit for the air outlet volume adjustment mechanism 4.

[0035] The air outlet pusher and the air outlet regulating end 51 are connected by the meshing of the transverse gear 44 and the longitudinal gear, forming an air outlet volume regulating mechanism 4 to control the rotation adjustment action of the air outlet mechanism 5. This further ensures that the air outlet pusher involved in the air outlet volume regulating mechanism 4 can be reliably supported after being placed in the housing 1. At the same time, after being supported, the air outlet volume regulating mechanism 4 can reliably rotate circumferentially on the support base 6. During synchronous rotation, there will be no situation where unreliable rotation causes overtravel, resulting in the air outlet mechanism 5 accidentally dislodging from the air storage mechanism 7 of the spray gun and causing damage to the spray gun.

[0036] like Figure 3 , 4 As shown in Figures 6, 7, 9, and 10, the ignition mechanism 2 includes a spring plate 28 abutting against the gas outlet mechanism 5, an electronic igniter 27 with a drive end 271, a linkage member 26 covering the drive end 271 and whose base 261 abuts against the spring plate 28, and an ignition component limited to the housing 1. The ignition component includes an ignition drive part distributed outside the housing 1 and an ignition linkage part extending into the housing 1 and distributed on one side of the linkage member 26. The ignition drive part and the ignition linkage part are linked together. The spray gun drives the ignition drive part, which generates driving force that is transmitted to the ignition linkage part, thereby driving the electronic igniter 27. The base 261 of the linkage member 26 drives the spring plate 28, thereby driving the gas outlet mechanism 5. Through the above, the ignition mechanism 2 involved in the spray gun can achieve reliable ignition control.

[0037] like Figure 1 , 2 As shown in Figures 6, 9, 11, and 12, the ignition drive unit includes an outer drive unit 21, a connecting rod 22, and an inner extension rod 27 arranged and connected in sequence. The ignition linkage unit includes a rotating disk 26 and a drive rod 25 connected to the rotating disk 26. The other end of the inner extension rod 27, which is connected to the connecting rod 22, extends into the housing 1. The rotating disk 26 is sleeved on the inner extension rod 27 and rotates synchronously with the inner extension rod 27. Through the above, the reliability of the ignition mechanism 2 in ignition control can be further guaranteed.

[0038] like Figure 1 , 2 As shown in Figures 6, 9, 11, and 12, the spray gun also includes decorative parts distributed outside the housing 1. The decorative parts include a first gear 24 sleeved on the inner extension rod 27 and rotating synchronously with the inner extension rod 27, a second gear 23 meshing with the first gear 24, and a fixing member 28. The second gear 23 is sleeved on the fixing member 28 and is limited to the housing 1 by the fixing member 28.

[0039] The spray gun is driven by the external drive unit 21 by the finger, and the force is transmitted sequentially between the connecting rod 22 and the inner extension rod 27, forming a rotation through the inner extension rod 27, which in turn drives the first gear component 24 to rotate. The component is used for the meshing rotation between the first gear component 24 and the second gear component 23. Through the above, when the spray gun is used with decorative parts, the gear components on the decorative parts can mesh and rotate accordingly, thereby ensuring that the spray gun involved in this utility model has a more beautiful appearance. At the same time, during the ignition process, the gear components can rotate synchronously, which also makes the spray gun more attractive to consumers and makes them more willing to purchase it.
