DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The embodiment of the present application discloses a hair dryer that is convenient for removing dust from the air inlet. Figure 1 and Figure 2 The hair dryer for dust removal at the air inlet comprises a handle 1, a head 2 and a filter dust removal assembly 3. The head 2 is arranged at one end of the handle 1, and an air outlet 21 is arranged on one side of the head 2. An outer cover sleeve 11 is detachably mounted on the end of the handle 1 away from the head 2, and an air inlet 12 is provided on the outer cover sleeve 11. The filter dust removal assembly 3 is inserted into the inner part of the outer cover sleeve 11, and when the air inlet 12 needs to be dusted, the outer cover sleeve 11 only needs to be removed from the handle 1, thereby improving the convenience of dust removal at the air inlet 12 of the hair dryer.

[0025] Reference Figure 1 and Figure 2 , a heating wire assembly module for heating the airflow is installed inside the machine head 2. A mounting cavity 13 is opened at one end of the outer cover sleeve 11 of the grip 1, and an inner liner 14 is installed inside the mounting cavity 13. The inner liner 14 is connected to the inside of the machine head 2, and a high-speed fan 15 is installed inside the inner liner 14. When the high-speed fan 15 is running, the airflow outside the hair dryer enters the inner liner 14 from the air inlet 12, and then the airflow is heated by the heating wire assembly module to form a hot airflow and is discharged from the air outlet 21. Among them, when the airflow enters the inner liner 14 from the air inlet 12, the airflow will pass through the filter dust removal component 3, and the filter dust removal component 3 will filter the dust in the airflow.

[0026] Reference Figure 1 and Figure 3The end of the inner liner 14 away from the machine head 2 protrudes from the installation cavity 13 and is exposed to the outside. The filter dust removal assembly 3 is sleeved on the part of the inner liner 14 exposed to the outside, and the filter dust removal assembly 3 is installed on the inner liner 14. The end of the outer cover sleeve 11 close to the handle 1 is inserted into the installation cavity 13 with interference fit. A plurality of blocking pieces 131 are integrally formed at intervals in the circumferential direction on the inner wall of the installation cavity 13. After the end of the outer cover sleeve 11 close to the handle 1 is inserted into the installation cavity 13, it will abut against the blocking piece 131, thereby limiting the depth of the outer cover sleeve 11 inserted into the installation cavity 13.

[0027] Combination Figure 1 Reference Figure 3 and Figure 4 The filter dust removal assembly 3 includes a filter screen 31 and a screen bracket 32. The filter screen 31 is a cylindrical filter screen, and the filter screen 31 is wrapped around the screen bracket 32 ​​and fixedly mounted on the screen bracket 32. The filter screen 31 is sleeved on the end of the inner tank 14 exposed in the installation cavity 13, and the end of the screen bracket 32 ​​close to the handle 1 is inserted into the installation cavity 13, and a blocking ring 132 is integrally formed on the inner wall of the installation cavity 13 to resist the screen bracket 32, so that the screen bracket 32 ​​can only be inserted to a certain length, so that most of the filter screen 31 is located in the outer cover sleeve 11 to filter the air inlet 12.

[0028] Reference Figure 1 and Figure 4 A fixing ear 321 is integrally formed on the inner wall of the mesh cover bracket 32 ​​away from the grip 1 , and a screw hole 322 is provided on the fixing ear 321 , through which a screw can pass to fix the mesh cover bracket 32 ​​on the inner liner 14 .

[0029] Reference Figure 1 and Figure 4 , wherein the outer wall of the filter screen cover 31 is wrapped with multiple layers of dust-removing adsorption tape 33, and the multiple layers of dust-removing adsorption tape 33 have the same structure. The following is explained by taking one layer of dust-removing adsorption tape 33 as an example. The dust-removing adsorption tape 33 is an arc-shaped tape wrapped on the filter outer cover. The dust-removing adsorption tape 33 is provided with multiple air intake holes corresponding to the through holes on the filter screen cover 31, so as not to affect the airflow outside the hair dryer entering the inside of the filter screen cover 31. A non-stick sheet 34 is fixedly provided on one side of the arc of the dust-removing adsorption tape 33, and the surface of the non-stick sheet 34 is a smooth surface without glue. When the surface of the dust-removing adsorption tape 33 is covered with dust, the non-stick sheet 34 can be used to easily tear this layer of dust-removing adsorption tape 33 from the filter screen cover 31.

[0030] The implementation principle of a hair dryer that is convenient for dust removal at the air inlet of the present application is as follows: when it is necessary to clean the dust at the air inlet 12 of the hair dryer, it is only necessary to unplug the outer cover sleeve 11 and then sweep away the dust adhering to the filter screen cover 31. It is not necessary to split the hair dryer housing into two halves, which makes it more convenient to remove dust at the air inlet 12 of the hair dryer. The dust adsorption tape 33 itself does not affect the air permeability of the filter screen cover 31. The dust at the air inlet 12 will be adsorbed on the dust adsorption tape 33. When it is necessary to clean it, the outer cover sleeve 11 is unplugged and then the dust adsorption tape 33 with dust adhering can be torn off through the non-stick sheet 34. Since the dust adsorption tape 33 is provided with multiple layers, it is only necessary to repeat the above-mentioned action for the next cleaning.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
