Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fire guns, in particular to a fire gun anti-scald structure. BACKGROUND

[0002] The current fire gun is a tool that uses combustible gas (such as butane or propane) to generate high-temperature flame, and is widely used in many fields, including but not limited to baking, barbecue, etc. In different application scenarios, the design and function of the fire gun may be different, but the basic principle is similar: by igniting the gas to generate a controllable flame.

[0003] The baking fire gun will consider safety factors in design, and will usually add an anti-scald structure outside the nozzle of the fire gun to protect the user from high-temperature injury. The commonly used anti-scald structure in the related art includes a protective cover for being sleeved outside the nozzle, which is circumferentially wrapped outside the nozzle. Under the protection of the protective cover, the user can be effectively prevented from directly contacting the nozzle surface, thereby achieving the effect of preventing the nozzle outer sidewall from being scalded.

[0004] For the above anti-scald structure, although it can prevent the nozzle from being scalded circumferentially, the temperature around the fire port of the nozzle will rise sharply after a long time of heating. However, the above protective cover cannot protect the area around the fire port, so if the user accidentally touches the just-heated fire port, the user will still be at risk of being scalded, and therefore the above anti-scald structure needs to be improved. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a fire gun anti-scald structure, which can effectively reduce the probability of the user being scalded by the fire port, further ensure the safety of the user, and improve the anti-scald effect.

[0008] Preferably, the anti-scald baffle is provided with side baffles, the side baffles are symmetrically arranged on both sides of the anti-scald pipe, and the side baffles on both sides of the anti-scald pipe are oppositely arranged.

[0009] Preferably, a front baffle is provided on the side of the anti-scalding baffle away from the anti-scalding tube, the front baffle is located between the two side baffles, and the front baffle is inclined downward.

[0010] Preferably, the anti-scalding baffle is provided with a connecting ring for being fitted onto the outside of the anti-scalding tube, and the connecting ring is threaded with a fastener for tightening and fixing the anti-scalding baffle onto the anti-scalding tube.

[0011] Preferably, the fastener is fitted with an anti-loosening gasket located between the anti-scalding baffle and the connecting ring.

[0012] Preferably, the fastener is further fitted with a rubber pad, which is located on the side of the anti-scalding baffle away from the anti-loosening pad.

[0013] Preferably, a limiting strip is provided on the outer wall of the anti-scalding tube, and the length of the limiting strip extends along the direction in which the connecting ring is sleeved on the outside of the anti-scalding tube; a limiting groove is provided on the inner wall of the connecting ring for interlocking with the limiting strip, and the connecting ring is limited to the outside of the anti-scalding tube by the interlocking of the limiting strip and the limiting groove.

[0014] Preferably, the inner wall of the anti-scalding baffle is provided with a high-temperature resistant heat insulation layer facing the anti-scalding tube.

[0016] It can greatly reduce the probability of users accidentally touching the flame nozzle, further ensuring user safety, improving the anti-scalding effect, and providing more comprehensive anti-scalding protection;

DETAILED DESCRIPTION

[0023] The application will be further described in detail below with reference to the accompanying drawings.

[0024] The application discloses an anti-scald structure of a fire gun. Embodiment one:

[0025] Reference Figure 1 , Figure 2 The anti-scald structure of the fire gun comprises an anti-scald pipe 1 used for being fixedly sleeved outside a nozzle of the fire gun. The anti-scald pipe 1 is externally provided with an anti-scald baffle 2 used for shielding a flame spout of the anti-scald pipe 1, and the anti-scald baffle 2 comprises a connecting section 200 and an extending section 201 which are integrally formed. The connecting section 200 is provided with a fastener 3 penetratingly arranged thereon, and the fastener 3 is in the form of a butterfly bolt in this embodiment.

[0026] As shown in Figure 1 , Figure 2 , the connecting section 200 is connected with a connecting ring 22 through the fastener 3, the connecting ring 22 is used for being sleeved outside the anti-scald pipe 1, the connecting ring 22 is provided with a threaded hole 220 penetratingly arranged thereon and used for allowing the fastener 3 to be screwed in the radial direction of the connecting ring 22, and the fastener 3 is inserted into and screwed in the threaded hole 220. The end of the fastener 3 screwed on the connecting ring 22 is in abutment with the outer side wall of the anti-scald pipe 1. The anti-scald baffle 2 is fixedly installed outside the anti-scald pipe 1 through the cooperation of the fastener 3 and the connecting ring 22.

[0027] As shown in Figure 1 , Figure 2 , the extending section 201 is located above the anti-scald pipe 1 and extends to the outside of the anti-scald pipe 1 in a direction away from the anti-scald pipe 1. The extending section 201 is obliquely downwardly arranged and shields the flame spout of the anti-scald pipe 1 through the extending section 201. Thus, the probability of a user accidentally touching the flame spout can be greatly reduced, the use safety of the user is further ensured, the anti-scald effect is improved, and the anti-scald protection is more comprehensive.

[0028] As shown in Figure 1 , Figure 2As shown, side baffles 20 are bent downwards on both sides of the extension section 201. The side baffles 20 are symmetrically arranged on the left and right sides of the anti-scalding tube 1, and are positioned opposite each other. A front baffle 21 is bent on the side of the anti-scalding tube 1 away from the anti-scalding tube 1. The front baffle 21 is located between the two side baffles 20 and is inclined downwards. By adjusting the installation position of the connecting ring 22 on the anti-scalding tube 1, the distance between the inner wall of the extension section 201 and the flame nozzle can be changed. With the baffle of the extension section 201, the spray range of the flame front end can be adjusted to meet the user's needs for different flame ranges.

[0029] After the flamethrower is used, the relatively large heat dissipation area of ​​the extension section 201 allows for rapid cooling, significantly reducing the risk of burns to the user. This ensures user safety and improves the anti-scalding effect.

[0030] like Figure 1 , Figure 2 As shown, two stacked anti-loosening washers 4 are fitted around the outside of the fastener 3, located between the connecting section 200 and the connecting ring 22. The anti-loosening washers 4 significantly enhance the anti-loosening effect of the fastener 3, ensuring a more stable and reliable tightening of the fastener 3 onto the connecting ring 22. A rubber pad 5 is also fitted around the outside of the fastener 3, located on the side of the connecting section 200 opposite to the anti-loosening washers 4. The rubber pad 5 further enhances the fastening effect of the fastener 3 on the anti-scalding baffle 2, ensuring the stability and reliability of the anti-scalding baffle 2. Example 2:

[0031] Unlike Example 1, referring to Figure 3 A limiting strip 10 is fixedly installed on the bottom outer wall of the anti-scalding tube 1. The length of the limiting strip 10 extends along the direction in which the connecting ring 22 is sleeved on the outside of the anti-scalding tube 1. A limiting groove 23 is provided on the inner wall of the connecting ring 22 for interlocking with the limiting strip 10. The connecting ring 22 is limited to the outside of the anti-scalding tube 1 through the interlocking of the limiting strip 10 and the limiting groove 23, which plays a positioning and guiding role in the installation of the connecting ring 22 and ensures the stability of the connecting ring 22.

[0032] like Figure 3 As shown, a high-temperature resistant heat insulation layer 24 facing the anti-scalding tube 1 is provided on the inner wall of the anti-scalding baffle 2. The specific high-temperature resistant heat insulation layer 24 can be made of high-temperature resistant and flame-retardant materials such as ceramic or mica.

[0033] The implementation principle is that the flame spout of the anti-scald pipe 1 is shielded through the extension section 201. Therefore, the probability of the user accidentally touching the flame spout can be greatly reduced, the use safety of the user is further ensured, the anti-scald effect is improved, and the anti-scald protection is more comprehensive. After the flame gun is used, the heat dissipation area of the extension section 201 is relatively large, so rapid cooling can be achieved, the risk of the user being scalded is greatly reduced, the use safety of the user is ensured, and the anti-scald effect is improved. The high-temperature-resistant heat insulation layer 24 can effectively inhibit heat transfer to the anti-scald baffle 2, so as to further improve the anti-scald effect.

[0034] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
