[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 1-4 The multi-duct self-blowing rust removal gun shown includes a gun head 6, a handle 1 is provided at the bottom of the gun head 6, and a fixing component is provided on the gun head 6. The fan compartment 2 is installed and fixed by the fixing component installed on the gun head 6. A group of air guide covers 5 are fixed to the front end of the gun head 6 by bolts. The air guide covers 5 are connected to the fan compartment 2 through an arc-shaped air duct pipe 4, and a fan 20 for exhausting air is provided in the fan compartment 2. When in use, the fan 20 is started through the electric control switch on the handle 1, and the air is drawn in from the rear of the fan compartment 2, and is sent to the air guide covers 5 through the air duct pipe 4, and then discharged from the air outlet 50 at the front end of the air guide covers 5 to achieve a blowing effect.

[0026] As an implementation method in this embodiment, in order to avoid floating particles in the air being drawn into the fan compartment 2 when the fan 20 is working, in this embodiment, a group of filters 3 are installed at the rear end of the fan compartment 2. When the fan 20 is working, the floating particles in the gas are filtered through the filters 3 to ensure the working efficiency of the fan 20.

[0027] As an implementation method in this embodiment, the fixing component: a group of fixing plates 11 are fixed by bolts at the rear end of the gun head 6, and a group of bottom plates 12 are fixed by bolts at the bottom of both ends of the fixing plate 11, and the fan compartment 2 is fixed to the top surface of the bottom plate 12 by bolts, and in order to further fix the fan compartment 2, a group of pressure plates 13 are provided on the top of the fan compartment 2, and the pressure plate 13 is also bolted to the top surface of the fixing plate 11.

[0028] As an implementation method in this embodiment, in order to facilitate the installation of the filter element 3, two groups of symmetrical installation holes 21 are provided on the fixing plate 11, and the installation holes 21 and the fan compartment 2 are interconnected.

[0029] As an implementation method in this embodiment, the two groups of symmetrical fan compartments 2 and air duct pipes 4 set in this embodiment not only improve the blowing effect, but also make the airflow in the air guide cover 5 blow forward symmetrically and evenly, avoiding turbulence in the air guide cover 5 during operation and enhancing the dust prevention effect.

[0030] As an implementation method in this embodiment, through the structural design of the air duct pipe 4, the diameter of the air inlet is larger than the diameter of the air outlet, so that the wind drawn by the fan 20 can be accelerated in the air duct pipe 4, thereby enhancing the blowing effect.

[0031] The working principle of the utility model is as follows: when the gun head 6 is being derusted, the electric control switch on the handle 1 is clicked, and the electric control switch starts the fan 20 in the fan chamber 2 to make the external gas flow in the direction of the filter element 3, and the filter element 3 is used to filter the gas, so that the filtered gas enters from the mounting hole 21 of the fixing plate 11 and the hole on the fan chamber 2, and then forms an airflow under the action of the fan 20 and is transported to the air duct pipe 4, and the airflow is accelerated through the structure of the air duct pipe 4, so that the gas is discharged from the air outlet 50 of the air guide cover 5, so as to prevent external dust and impurities from approaching the protective lens of the gun head 6, and achieve the rust removal task. After completing the task, the cover can be re-covered on the air guide cover 5 to keep it dust-proof;

[0032] When the fan 20 in the fan compartment 2 needs to be maintained, the pressure plate 13 is removed from the fixing plate 11, and then the fan compartment 2 is removed from the bottom plate 12 to clean the inside thereof. At the same time, the air guide cover 5 and the air duct pipe 4 can also be removed to clean the inside thereof.
