DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] As Figures 1-5 shown, the present application provides an efficient energy-saving hot air gun, which comprises a protective shell 1, the protective shell 1 is provided with a tubular structure, and a tubular blow pipe 102 is fixed on one side of the protective shell 1, a spiral groove structure is formed in the inner side of the blow pipe 102, the spiral structure reduces the wind resistance, and the ventilation efficiency is high, the blow pipe 102 is provided with a blowout 101 away from one side of the protective shell 1, the other side of the protective shell 1 is provided with an air inlet 103, a handle 6 is fixed on the side of the protective shell 1, and the protective shell 1 further comprises a heat dissipation assembly 2 and a dustproof assembly 5: a rotating groove 201 is formed in the outer side of the blow pipe 102, the heat dissipation assembly 2 is arranged at the rotating groove 201, the heat dissipation assembly 2 comprises a heat shield 202, and the heat shield 202 is slidably connected with the rotating groove 201; an annular groove 104 is formed in the protective shell 1 near the air inlet 103, the dustproof assembly 5 is arranged in the annular groove 104, and the dustproof assembly 5 comprises a filter plate 501, and the filter plate 501 is movably connected with the annular groove 104.

[0027] As Figures 1-5As shown, the air blowing pipe 102 is provided with an air outlet 203 at the outside rotary groove 201, and a plurality of heat dissipation openings 204 are uniformly provided in the side wall of the air blowing pipe 102 and arranged in the same direction as the axis of the protective shell 1. The heat dissipation openings 204 are also provided at the connection between the side of the protective shell 1 and the rotary groove 201, and are used for heat dissipation of the protective shell 1 and the air blowing pipe 102. The heat shield 202 is provided with an exhaust groove 205 on the inner side, which is parallel to the axis of the protective shell 1. The number of the exhaust groove 205 corresponds to the number of the air outlet 203 and the heat dissipation opening 204. The heat shield 202 is made of heat insulation material.

[0028] As shown in the drawings, Figures 2-3 The dustproof assembly 5 further comprises a spring 503, one end of which is connected with the annular groove 104 and the other end of which is connected with the filter plate 501. A top block 505 is fixedly arranged in the annular groove 104 near the air inlet 103. The filter plate 501 is movably connected with the top block 505. A slotted groove 502 is provided in the bottom of the protective shell 1 near the air inlet 103. The filter plate 501 is provided with a push block 504 at the bottom, which is slidably connected with the slotted groove 502.

[0029] In use, when the hot air gun is needed to work, the heat shield 202 is rotated so that the exhaust groove 205 in the heat shield 202 is not aligned with the heat dissipation opening 204 and the air outlet 203, thereby completing the plugging of the heat dissipation opening 204 and the rotary groove 201. This avoids the heat from escaping from the heat dissipation opening 204 during the air blowing, thereby ensuring the working efficiency, saving energy and being energy efficient.

[0031] When the working is completed and heat dissipation is needed, the heat shield 202 is rotated so that the exhaust groove 205 in the heat shield 202 is completely connected with the heat dissipation opening 204 and the air outlet 203. The heat in the protective shell 1 is discharged from the heat dissipation opening 204 along the exhaust groove 205 and the air outlet 203, thereby completing the heat dissipation.

[0032] When the filter plate 501 needs to be cleaned after the working of the device is completed, the push block 504 is pushed to slide along the slotted groove 502, thereby driving the filter plate 501 to press the spring 503. The pressing of the push block 504 is released, and the filter plate 501 and the top block 505 collide under the rebounding action of the spring 503. The dust on the filter plate 501 falls along the slotted groove 502, thereby conveniently cleaning the dust.

[0033] The above describes the present application and its embodiments, which are not restrictive, and the drawings only show one of the embodiments of the present application, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired, without departing from the spirit of the present application, without creative design, similar structure and embodiments of the technical solution, which should belong to the protection scope of the present application.
