Description

Technical Field

[0001] The utility model relates to the technical field of hot air gun protection, in particular to a scalding-proof hot air gun. Background Art

[0002] The hot air gun is mainly a tool that uses the hot air blown out of the gun core of the heating resistor wire to weld and remove components. In the existing plastic production and processing, the hot air gun is needed to heat the plastic products for later production and processing. In the patent document of a hot air gun with anti-scalding function disclosed by announcement number CN 219346797 U, it is provided with an anti-scalding sleeve, a moving block, a first magnetic block, a second magnetic block and a tension spring. The anti-scalding sleeve is installed by sliding in the slot on the left side of the hot air gun body. When the hot air gun body is started to drive the fan to blow air, the anti-scalding sleeve will be driven to move, and then the moving blocks installed at the upper and lower ends of the anti-scalding sleeve can be driven to slide in the moving slots opened on the upper and lower sides of the hot air gun body, and then the air outlet can be used for anti-scalding protection. Although this method can cover the air outlet for anti-scalding protection. However, since the anti-scalding sleeve is closed on all sides with only one opening, it is not conducive to heat dissipation from the air outlet, and a large amount of heat will still be transferred to the anti-scalding sleeve during the heat dissipation process, which may cause burns to the user. Utility Model Content

[0003] The utility model mainly provides a scalding-proof hot air gun, which solves the problems in the prior art that the scalding-proof sleeve is closed on all sides with only one opening, which is not conducive to heat dissipation at the air outlet, and a large amount of heat will still be transferred to the scalding-proof sleeve during the heat dissipation process, which may cause scalding to the user.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A scalding-proof hot air gun comprises a hot air gun body, on which an anti-scalding device is installed; the anti-scalding device comprises a fixed seat installed on the hot air gun body, a power assembly is installed on the hot air gun body, and an anti-scalding frame is installed on the fixed seat, and the power assembly is used to drive the anti-scalding frame to move forward and backward. Among them, each component in the present application can be powered by a power module. When in use, the anti-scalding frame is driven to move forward and backward by the power assembly, so as to cover the air outlet of the hot air gun body. With the structure of the present application, the anti-scalding frame can be driven to move forward and backward by the power assembly without affecting the use of the hot air gun, and a protection range is formed to prevent the operator from directly touching the air outlet of the hot air gun body and getting scalded, and the anti-scalding frame can be used to effectively dissipate heat.

[0006] Furthermore, the anti-scalding rack includes a plurality of rack rods and a middle fixing ring installed on the rack rods; a rod hole matching the rack rod is opened on the fixing seat, the rack rod is slidably connected in the rod hole, and the rear end of the rack rod passes through the fixing seat; the output end of the power assembly is fixedly connected to the rear end of any rack rod. With this structure, a ring covering the air outlet of the hot air gun body can be formed on the fixing seat through multiple rack rods, and the structure of the multiple rack rods is made more stable through the middle fixing ring. At the same time, the gaps between the rack rods can more efficiently dissipate heat from the air outlet of the hot air gun body, thereby preventing the rack rods from absorbing a large amount of heat and causing burns to the user.

[0007] Furthermore, the power assembly adopts a cylinder, and the output end of the cylinder is fixedly connected to the rear end of any of the racks. The cylinder can conveniently move the racks of the underground hole forward and backward on the fixed seat.

[0008] Furthermore, a front fixing ring is installed at the front end of the rack rod. With this structure, the front end structure of the rack rod can be further fixed.

[0009] Furthermore, one end of a support rod is rotatably connected to the front fixing ring, and a cleaning brush is installed on the support rod, and the cleaning brush rotates on the front fixing ring driven by the support rod. When in use, the support rod can be rotated, thereby driving the cleaning brush to rotate with the front fixing ring as a fulcrum, thereby reaching the front side of the air outlet of the hot air gun body, and the front grille of the air outlet of the hot air gun body is cleaned by rotating the cleaning brush.

[0010] Furthermore, a mounting hole is provided on the support rod, and the rotating shaft of the cleaning brush is installed in the mounting hole through a bearing, and the outer end of the rotating shaft passes through the outside of the support rod. The structure is simple, and the cleaning brush can be rotated by rotating the rotating shaft to perform cleaning.

[0011] Furthermore, a screw cap is installed at the outer end of the rotating shaft. This structure can facilitate the rotation of the rotating shaft.

[0012] Furthermore, a temperature sensor for detecting the temperature information of the air outlet of the hot air gun body is installed on the fixing base, and a display for receiving and displaying the temperature information is installed on the fixing base. The connection between the display and the temperature sensor can adopt any existing connection method, such as: electrical connection, signal connection. The probe of the temperature sensor points to or is located outside the air outlet of the hot air gun body, and the temperature information of the air outlet can be detected by the temperature sensor, and the temperature information is sent to the display for display.

[0013] Beneficial effects: By adopting the structure of the present application, the anti-scalding rack can be driven to move forward and backward through the power component without affecting the use of the hot air gun, thereby forming a protection range to prevent the operator from directly touching the air outlet of the hot air gun body and getting burned, and the anti-scalding rack can effectively dissipate heat.
