New description: [New technical field] The type of the table is on the side of the shell. This is a kind of hair dryer, especially related to the opening of the hole, the peak of the orchid, although the material and the second [previous technology] I hair dryer is already a kind of necessary household appliances, especially in the hair cleaning meeting, the sister machine to reduce the money or the cold wind, the hair that is air-dried and damp, and even its lion-like items, is also air-dried by f_hair dryer (four). In the case of a general hair dryer structure, there is generally a casing, and a small AC or DC motor is housed inside the casing. A fan is connected to the rotating shaft of the motor, and the fan is rotated by the rotation of the motor (four) to drive the fan. Rotate, push the button, so that the air is sucked in by the air inlet of the blower and blown out by the air outlet of the casing. However, the hair dryer of the above configuration has high noise and short product life in use, and φ is vortex (turbulent flow) due to the fan, and high frequency chewing is generated by hitting the casing, which causes the noise of the blower to operate considerably, affecting The user's hearing is very large and causes discomfort. [New content] In view of the above-mentioned problems of the prior art, the purpose of the present invention is to provide a hair dryer to solve the problem that the noise generated by the hair dryer of the prior art is uncomfortable to the user. According to the purpose of the present invention, a hair dryer is provided, which comprises a hair dryer body M359962 and a casing. The hair dryer body has a wind module. The casing is covered on the side edge of the casing body with a human wind grid and a wind. Grid and at least - holes, holes and holes = suspicion of which 'holes and secrets the money tree when the shouting flow and increase the inhaled 0. The holes are round, polygonal or circular holes. [Embodiment] The related drawings illustrate the embodiment of the hair dryer according to the present invention. For the sake of easy understanding, the following components of the actual patch are as follows. 1 ffi, which is the first embodiment of the hair dryer of the present invention. The low noise blower comprises a hair dryer body u, an integrated ui and at least one hole 丨 2. The housing 1U is covered with a hair dryer body. The hole body is formed on the casing. The blower body further includes an air inlet grille 112, an air outlet ID and a air supply module (not shown), and includes a circuit controller, a heating module and a fan. The fan group includes a motor and a fan, and the fan system includes at least one fan blade. The air sucked by the air grille m is heated by the heating module to increase the air temperature, and then the high temperature air is blown out by the air outlet grille U3. The air outlet grille U3 can be further provided with a windshield to increase the wind blown by the blower. The windshield 112 can be set-filtered. The circuit controller adjusts the motor to adjust the wind of the low noise machine. a circular, polygonal or circular hole, because when the air flows in the casing, a vortex (v〇rtex) flow field structure is formed by randomly vortexing anywhere in the casing due to random impact on the casing. Flowing gas M 359962 The body and the housing resonate to make the blower produce noise. By setting this hole i2, it can disrupt and eliminate the leakage of the airflow due to one end of the fan. Yang Hongwei, which has the effect of reducing the fan group's lion's life (four) sounds and increasing the amount of air drawn by the age-testing flow field. The hole 12 series is a square shell arranged symmetrically or randomly (rand〇m). The upper hole (four) (10) is in the form of a single leak (4) and is disposed on the casing m with respect to the fan blade. The hole 12 is arranged at an oblique angle to open on the casing 111. Thereby, the hole 12 can be increased. The air inlet surface has the effect of improving the air volume and reducing the vibration sound generated when the hair dryer body is running. Further, the hole 12 can be provided with a mesh structure to prevent the foreign matter from being caught. In addition, the material of the & body (1) may be a hard material such as a metal material or a plastic material. Please refer to Fig. 2, which is a schematic view of the opening of the second embodiment of the hair dryer of the present invention. In the figure, the holes 12 are formed on the casing U1. The holes 12 are opened in a random manner on the casing U1, and the holes are circular, polygonal or circular. It is worthwhile to raise it. In the second figure, the ^-shaped hole is opened on the shell in, and a mesh structure i2i is added to the square hole. Thus, _ not only is not afraid of foreign matter entering the hair dryer, but it can be eliminated. By the way, the effect of eliminating noise can be achieved. a 9 Please refer to Fig. 3, which is a schematic view of the opening of the third embodiment of the hair dryer of the present invention. In the figure, the hole 12 opened in the casing 111 is an annular hole. It is worth mentioning that, as described in Figure 1, the hole 12 is used to eliminate the eddy current generated when the fan unit is running, so the annular hole can further eliminate the eddy current generated during the wind operation and reduce it. The sound produced by the operation of the hair dryer. The above is intended to be illustrative only and not limiting. Any changes that are not divorced from the spirit of this creation 5 M359962 and the work of the Department (4) shall be included in the scope of the patent application attached.
