Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Example one
The present embodiment discloses an electric hair dryer. As shown in fig. 1 and 2, the electric hair dryer includes a blowing cylinder 1 and a filtering device, wherein the blowing cylinder 1 is provided with an air inlet 11 and an air outlet 12, and the filtering device is arranged at one side of the air inlet 11. The air enters the air duct in the air blowing tube 1 after passing through the filtering device on one side of the air inlet 11, the filtering device effectively removes dust in the air inlet, the heating efficiency of the heating wire is improved, and the user experience is improved.
The filtering device is arranged at the same side or the other side of the air inlet 11 relative to the air outlet 12, and the using effect is not influenced; the filtering device and the barrel body at the air inlet side of the air blowing barrel 1 are integrally arranged or detachably connected, and the dust filtering capacity in the air inlet is the same.
The filtering device comprises a supporting part 21, a filter screen 22 and a protective cover 23 which are sequentially sleeved from inside to outside, the axis of the filter screen 22 is parallel to or coincided with the axis of the air blowing cylinder 1, and the filter screen 22 and the protective cover 23 are preferably cylindrical. One side end face of the protective cover 23 is connected to the air inlet 11, and the other side end face is provided with a closed protective cover, and the side face is of a hollow structure. The curve with an arrow in fig. 1 is a flow path line of the intake air, that is, the intake air enters the filter device from the side and enters the air blowing cylinder 1 after turning. The bent inlet air path helps to reduce the wind speed, so that more dust can be intercepted on the filter device instead of being carried by the high speed wind to rush into the barrel 1.
The support part 21 includes a plurality of skeletons symmetrically arranged about the axis of the filter net 22, and is used for supporting the filter net 22 and avoiding the deformation of the filter net 22; the position that contacts with filter screen 22 on the safety cover 23 comprises the many guard posts of setting about the axis symmetry of filter screen 22, forms hollow out construction, does not hinder the air inlet and gets into section of thick bamboo 1 of blowing through filter screen 22 when fixed filter screen 22.
The filter screen 22 is formed by curling sheet metal, and a plurality of filter holes are formed in the sheet metal and used for intercepting objects such as hair, dust and the like in the inlet air. Preferably, the diameter of the filter holes is less than or equal to 0.5mm, so that the dust blocking effect is better, and the air inlet amount cannot be reduced.
Example two
The present embodiment discloses an electric hair dryer, which has the same basic structure as the first embodiment. The difference is that the filter device comprises a metal filter mesh 24, a filter cloth 25 and a sealing edge 26, as shown in fig. 3. The metal filter screen 24 comprises an inner layer and an outer layer, preferably, the two metal filter screens 24 are arranged in a staggered mode (the meshes are not aligned), so that the clamping and supporting effects on the filter cloth 25 are better; the filter cloth 25 is arranged between the two layers of metal filter screens 24 and used for intercepting dust in the inlet air, and the filter cloth 25 is preferably made of non-woven fabrics or other high-permeability materials; the sealing edge 26 is an annular structure, and connects the side edges of the two metal filter screens 24 together, and seals the filter cloth 25 in the structure enclosed by the two metal filter screens 24 and the sealing edge 26. The end surface of the sealing edge 26 is connected with the air inlet of the air blowing tube 1, and the straight line with an arrow in fig. 3 is used for showing an air inlet route, so that dust in the inlet air can be effectively removed while the air inlet speed and the air inlet amount are not influenced.
The aperture ratio of the filter cloth 25 such as non-woven fabrics is smaller, small particle foreign matters such as dust in the air inlet can be intercepted more thoroughly, the inside of the air blowing cylinder 1 is cleaner, the heating efficiency of the heating wires is higher, and the air outlet is cleaner.
It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
