[0025] The technical solutions in the embodiments of the present application will be described clearly and completely 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. 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 1-6The utility model discloses an electric hair dryer convenient to dismount filter screen 4, including casing 1, switch 2, the air inlet 12 of located casing 1 front side and rear side air inlet 33, heating element (not drawn in the drawing) located in casing 1, fan blade 13 and be used for driving fan blade 13 to rotate motor 14, after switch 2 is pressed by switching on the power (switch 2 realizes motor 14 start for prior art, its principle and wiring mode do not make specific elaboration here), current flows to motor 14 at this time, makes its output shaft start rotating and drives fan blade 13 to drive and produce airflow, simultaneously, current will flow to heating element (common such as resistance wire), make it heat, fan blade 13 rotates and makes the airflow from air inlet 33 move towards air outlet 12, and this part of airflow is heated by heating element and becomes hot air and is sprayed from air outlet 12, thereby rapidly evaporating the water seal on the hair and achieving the effect of fast drying (this is prior art, not specific elaboration here), still include air inlet seat 3 and the filter screen 4 of detachable installation in air inlet seat 3 through bolt, buckling etc., air inlet 33 is located on air inlet seat 3, casing 1 includes rear side limit seat 11, heating element, motor 14, fan blade 13 all are located in the front side of limit seat 11, filter screen 4 is located in air inlet seat 3 and with the rear side end surface of limit seat 11 abuts, air inlet seat 3 and limit seat 11 are detachably connected through magnetic attraction, buckling etc., 1.filter screen 4 on air inlet seat 3 can make in the process of starting fan blade 13 and driving airflow from air inlet 33 to air outlet 12, the impurities mixed by external gas can be intercepted in the process of moving towards air outlet 12 by filter screen 4 and be blocked in the rear side of filter screen 4 and cannot move forward towards air outlet 12, so can prevent dust and sundries from entering the inside of electric hair dryer and affect its performance or cause security risks, 2.simultaneously since filter screen 4 abuts with limit seat 11, when needing to clean filter screen 4 on air inlet seat 3, since air inlet seat 3 is connected with limit seat 11 at this time, can directly contact filter screen 4 after taking down air inlet seat 3, then separates filter screen 4 and air inlet seat 3 and can realize the overall cleaning of filter screen 4, simultaneously, since limit seat 11 exists, in the process of disassembling air inlet seat 3 and filter screen 4 on air inlet seat 3, do not directly contact heating element, motor 14, fan blade 13 etc.

[0027] Among them, the number of air inlets 33 is several, each air inlet 33 is spaced along the radial direction of the rear end surface of the air inlet seat 3 and penetrates the air inlet seat 3, since the rear end surface of the air inlet seat 3 is provided with several air inlets 33, when the switch 2 is pressed to start the motor 14 and drive the fan blade 13 to rotate, the heating element is hot, the external air can more rapidly and efficiently enter the casing 1 through each air inlet 33 to flow towards the air outlet 12, thereby improving the drying efficiency of the hair.

[0028] Preferably, each of the air inlets 33 is arranged in an arc shape with the opening facing the inside. Since each air inlet 33 is arranged in an arc shape, more gas of different heights can directly flow into the air inlet 33 compared to an air inlet 33 arranged in a rectangular shape, thereby improving the efficiency of external air entering the shell 1, and the arc-shaped air inlet 33 can improve the aesthetics of the rear end surface of the air inlet seat 3.

[0029] Preferably, the cross section of each air inlet 33 is arranged in a stepped shape with the front narrow and the rear wide. Since the cross section of each air inlet 33 is arranged in a stepped shape, the external gas first enters the rear side of each air inlet 33, i.e. the side with the maximum width, and then smoothly flows towards the rear side of each air inlet 33. Since the front side of each air inlet 33 is narrower than the rear side, substances with a diameter larger than the cross section of the front side of each air inlet 33 will be intercepted by the front side of each air inlet 33 and cannot move towards the air outlet 12, thereby achieving preliminary filtration of the air entering the air inlet 33.

[0030] The filter screen 4 includes a plurality of filter holes 41 arranged in a circumferential direction and spaced apart from each other and in communication with the air inlets 33. Each filter hole 41 is arranged in a flared shape from the front to the rear, and the diameter of the rear side of each filter hole 41 is smaller than the width of the cross section of the front side of each air inlet 33. Therefore, impurities contained in the gas passing through each air inlet 33 will be blocked by each filter hole 41 when entering the rear side of the filter screen 4, thereby achieving secondary filtration and enhancing the overall efficiency of the hair dryer.

[0031] Preferably, the filter screen 4 is circumferentially protruding and provided with a plurality of connecting blocks 42. The air inlet seat 3 is made of a material that can be easily deformed, such as rubber, and is provided with a connecting slot 31 corresponding to each connecting block 42. When the filter screen 4 is installed in the air inlet seat 3, the connecting block 42 in the process of the air inlet seat 3 being deformed and then being fitted on the filter screen 4 will enter the corresponding connecting slot 31, thereby ensuring the stability of the filter screen 4 in the air inlet seat 3. When there is no external force to disassemble the air inlet seat 3 and the limiting seat 11, unrelated personnel cannot touch the filter screen 4, thereby improving the safety of the hair dryer. By deforming the air inlet seat 3 outward, the connecting block 42 can be separated from the corresponding connecting slot 31, and the filter screen 4 can be taken out for cleaning.

[0032] Preferably, the limiting seat 11 is provided with a limiting ring 111 protruding in the circumferential direction, the air inlet seat 3 is provided with a limiting groove 32 corresponding to the limiting ring 111, the cross section of the limiting ring 111 is in the shape of a trapezoid with the outside narrow and the inside wide, the limiting ring 111 is arranged so that when the air inlet seat 3 is sleeved on the limiting seat 11 in the circumferential direction, the air inlet seat 3 can forcibly pass over the limiting ring 111, and then the limiting ring 111 falls into the limiting groove 32 to determine the relative position of the air inlet seat 3 and the limiting seat 11, and when the limiting seat 11 and the air inlet seat 3 are separated, the limiting ring 111 is separated from the limiting groove 32 by applying an outward force to the air inlet seat 3, and then the filter screen 4 is separated from the air inlet seat 3 to realize the overall cleaning of the filter screen 4.

[0033] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
