[0021] like Figures 1 to 4As shown, a detachable hair dryer comprises a hair dryer 1 and a handle portion 2, wherein the hair dryer 1 and the handle portion 2 are connected to form a T shape, a cover 3 is detachably mounted on the rear end of the hair dryer 1, a plurality of protrusions 11 are arranged on the inner ring of the rear end of the hair dryer 1, a plurality of slots 32 are arranged on the inner ring 31 of the cover 3 corresponding to the protrusions 11, the protrusions 11 are movably snap-fitted into the slots 32 in a one-to-one correspondence, the slots 32 comprise an outlet position 321 and a snap-fitting position 322, the outlet position 321 is arranged at the circle mouth of the inner ring 31, the snap-fitting position 322 is connected with the outlet position 321, the outlet position 321 is used to guide the protrusion 11 to enter the snap-fitting position 322 for snap-fitting, an air inlet 21 is arranged on the end of the handle portion 2 away from the hair dryer 1, a filter assembly 4 is arranged in the air inlet 21. Specifically, in this embodiment, the wind tube 1 is connected to the handle 2, so that the fan in the wind tube 1 can draw in the outside air through the handle 2, and blow it out from the front end of the wind tube 1 after pressurization, completing the blowing process. In order to prevent the rear end of the wind tube 1 from entering, we use a cover 3 to block it. The cover 3 is detachable, which is convenient for removing the cover 3 to maintain the fan in the wind tube 1. An inner ring 31 is provided on the side of the cover 3 facing the wind tube 1. The inner ring 31 is used to be inserted into the wind tube 1. A plurality of slots 32 are provided on the outer ring surface of the inner ring 31. The slots 32 are engaged with the protrusions 11 in the wind tube 1 one by one. The card slot 32 includes an outlet position 321 and a card connection position 322. When the card connection is made, the user rotates and presses the cover 3. When the protrusion 11 is aligned with the outlet position 321, the cover 3 is automatically carded into the outlet position 321. At this time, the user continues to rotate the cover 3, so that the protrusion 11 enters the card connection position 322 from the outlet position 321, thereby preventing the cover 3 from easily detaching from the rear end of the wind tube 1 by relying solely on the elastic extrusion fit between the cover 3 and the wind tube 1. The outlet position 321 and the card connection position 322 can firmly lock the protrusion 11, so that the cover 3 and the wind tube 1 are not easily separated. It can be understood that the rear end of the hair dryer 1 of the present design is sealed with a cover 3, so that when blowing air, air is taken in through the handle portion 2. Specifically, an air inlet 21 is provided at the lower end of the handle portion 2, that is, the end away from the hair dryer 1, and a filter component 4 is provided in the air inlet 21. The filter component 4 is utilized to filter the intake air and filter dust in the gas, so that the gas blown out is cleaner, the dust adsorbed on the fan and the heating screen in the hair dryer 1 is reduced, and the frequency of disassembly and maintenance is reduced.

[0022] like Figure 4 As shown, the filter assembly 4 includes a filter screen 41 and a frame 42, the filter screen 41 is installed in the frame 42, and the frame 42 is detachably connected to the inner wall of the air inlet cylinder 21. Specifically, in this embodiment, the frame 42 is made of metal or plastic and is detachably connected to the inner wall of the air inlet cylinder 21, so as to facilitate the removal and cleaning of dust and the like attached to the filter screen 41.

[0023] like Figure 4As shown, the filter assembly 4 also includes a vibrator 43, and a hollow position 411 is provided in the middle of the filter 41, and the vibrator 43 is installed in the hollow position 411. Specifically, in order to reduce the frequency of disassembling and cleaning the filter assembly 4 and realize automatic cleaning of the filter 41, we set a hollow position 411 in the filter 41. The filter 41 is cylindrical as a whole and is made of flexible porous material, with good air permeability and strong adhesion to dust and other particles. When the vibrator 43 is powered on, it vibrates in the filter 41, and the dust and the like attached to the filter 41 can be shaken off and discharged through the air inlet 21, thereby realizing automatic cleaning.

[0024] like Figure 4 As shown, a clamping column 421 is provided on the outer side of the frame 42, and a mounting groove 211 is provided on the inner wall of the air inlet tube 21 corresponding to the clamping column 421. Specifically, the clamping column 421 is assembled into the mounting groove 211, and then a bolt is screwed on the end of the clamping column 421 to complete the assembly, which is simple and convenient to operate, and stable and reliable.

[0025] like Figure 4 As shown, the filter 41 is also provided with a channel 412, and the channel 412 is used to connect the outside world with the air duct of the handle 2, and a solenoid valve is installed in the channel 412. Specifically, in this embodiment, the filter 41 is provided with a channel 412, and the function of the channel 412 is to directly connect with the outside world, especially when the user uses the high-power mode to blow air, the resistance to the gas when the gas passes through the filter 41 is relatively large, and at this time, the air intake is small, which is not suitable for the high-power mode. At this time, the solenoid valve is turned on, and the gas can directly enter the handle 2 through the channel 412, and the user's experience is better with multiple modes of blowing.

[0026] like Figures 1 to 3 As shown, the handle portion 2 is provided with a control button 22, which is convenient for the user to control the start and stop of the fan in the hair dryer 1 through the button 22, and to blow hot air or cold air, which is extremely convenient and quick to operate.

[0027] like Figures 2-3 As shown, a convex point 3221 is provided in the engaging position 322, and a concave portion 111 is provided on the surface of the protrusion 11 corresponding to the convex point 3221. Specifically, in this embodiment, the convex point 3221 cooperates with the concave portion 111 to complete the position limiting, avoiding loosening and reverse of the cover 3.

[0028] like Figure 3As shown, a slide bar 112 is provided on the side of the protrusion 11 facing the rear end port of the wind tube 1. Specifically, when the user screws the cover 3 into the rear end of the wind tube 1, because the slide bar 112 is provided on the side close to the rear end port of the wind tube 1, it can guide the inner ring 31 of the cover 3 and squeeze the inner ring 31 to slightly deform it, making it easier for the slot 32 to fit with the protrusion 11 when screwing.

[0029] Specifically, the number of the protrusions 11 is four, and they are evenly spaced around the central axis of the wind tube 1, and the number of the slots 32 is correspondingly set to four.

[0030] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
