New description: [New technical field] This creation department has a fan-type fan that can reduce the flow of the fan. The sister can reduce the noise generated when the fan is running. [Prior Art] According to 'Because China is located in a subtropical climate zone, the summer climate is hot. Therefore, it is a common method to use a fan that sends air exhaust air indoors to maintain indoor and outdoor air circulation and reduce internal temperature. And can effectively save air-conditioning costs. The conventional exhaust fan or suction fan is as shown in the new patent No. 87203743 of China, "The type of row, suction fan frame and blade car is improved by the positioning and reinforcing rib structure", and has a frame and is mounted on the frame. Blade shafts, blades, gorges and motors. When the fan is running, the gas is sucked by the fan-end, and the fan is blown out at one end to achieve the function of suction and exhaust. However, it has been found through use that such conventional fans are less than ideal in use. Because the frame of the fan is thin and the depth is short, the human air outlet is quite close to the air outlet, and the airflow will be from the four-faced green man, and the air can not be collected from the wind (four) fan. When the conventional fan is used, some of the gas only circulates at the air outlet, that is, the airflow near the air outlet is also sucked by the fan. This causes the thief and money to be generated, so that the efficiency of the fan's exhaust and exhaust is not Zhang, the electricity consumption fee. Furthermore, the turbulence and turbulence of the airflow will increase the arm sound when the fan is running. [New content] The main purpose of this creation is to provide a fan that allows the fan to have better exhaust/suction efficiency. 3 M365414 Another object of this creation is to provide a fan with better efficiency as described above, which can effectively reduce the volume generated when the fan is running. In order to achieve the purpose of the above, the fan provided by the creative department includes: a casing with a limb air chamber inside, and the second end of the wind chamber is divided into a human air outlet and an air outlet, the entrance and exit The tuyere is maintained at a considerable distance; a sound-absorbing space is arranged in the casing to surround the air chamber; a plurality of sound-absorbing holes are arranged on the circumferential surface of the air chamber to connect the air chamber and the sound-absorbing space; a blade member disposed in the plenum of the casing, the motor driving the blade member to rotate; and a sound absorbing member disposed in the silencing space. The airflow can be concentratedly sucked into the fan by the air inlet, and then discharged from the air outlet, which can reduce the occurrence of turbulence and turbulence, thereby generating the efficiency of the thief; _, the sound wave of the airflow is consumed by the sound absorbing member, Reduce noise. [Embodiment] In order to further understand the purpose, features and effects of the present invention, a preferred embodiment of the present invention will be described, and further illustrated with the accompanying drawings. The first figure is a perspective view of a preferred embodiment of the present invention. The second drawing is an exploded perspective partial cross-sectional view of the first figure. The third drawing is a longitudinal sectional view of a preferred embodiment of the present invention. The fourth figure is a cross-sectional view taken along line 4-4 of the third figure. Referring to the first and second figures, a fan (10) provided by the present invention is provided with a casing (20), a motor (30) and a blade member (4〇), wherein: In the embodiment, the casing (20) is a rectangular frame, but not limited thereto, other configurations can be made. a tubular plenum (22) is disposed in the center of the casing (20) and extends through the two ends of the casing. The M365414 plenum (22)-end forms a fan inlet (23), as shown in the third figure. The other end forms the air outlet (24) of the fan, and the human air outlet (23) and the outgoing air π (24) are quite close to her. Referring to the fourth figure, the casing (20) is hollow "the interior thereof forms a sound-removing hollow 25", and the silencing space (25) is located at the periphery of the air chamber (22), that is, around the wind chamber. . A plurality of sound-absorbing holes (26) are densely disposed on the circumferential surface of the air chamber (22) such that the air chamber communicates with the silencing space (25). The motor (30) is disposed in the wind chamber (22) of the casing (20). A bracket (35), as shown in the first to third figures, is fixed to the casing (20). The bracket may have a zigzag shape or other configuration, and is not limited to the embodiment. Preferably, the bracket is fixed in the wind chamber (22); the motor (3) is fixed to the bracket (35) by a base (34), thereby being installed in the wind chamber (22). In addition, the motor is connected to a knob or button (not shown) to control its operation and to switch its speed. The blade member (40) has a leaf shaft (42) and a plurality of blades (44) that are connected to the circumferential surface of the blade shaft (42) at equal intervals. The blade (44) and the blade shaft (42) may be integrally formed, or the blade and the blade shaft may be separately formed, and the blade is assembled on the blade shaft. The blade member (4) is coupled to the rotating shaft (32) of the motor (30) by the blade shaft (42), and is accommodated in the air chamber (22) by the motor to drive the blades (44). A sound absorbing member (50)' may be a sound absorbing cotton or other object having a sound absorbing effect, such as a porous material. The sound absorbing member (50) is installed in the silencing space (25) of the casing (20) as shown in the second and fourth figures. Preferably, the sound absorbing member (50) fills the silencing space (25). When in use, install the fan (10) of this creation in the position to be sucked/exhausted, and connect the motor (30) to the power supply. When the fan (10) is in operation, the motor (3〇) drives the blade member (4〇) to rotate 'intake the gas from the air inlet (23) into the fan, and the airflow flows through the air chamber (22) from the air outlet (24) Drain the fan. 5 M365414 By the above design 'Because the distance between the air inlet (23) and the air outlet (24) is 'disturbed', there is a significant separation between the gas inlet and outlet, and the airflow will be concentrated from the air inlet (23). After the suction fan ' flows through the plenum (22), it is discharged by the air outlet (24), so that no turbulence or turbulence is generated, which has the best inhalation/efficiency. Furthermore, the sound wave when the gas flows will flow into the silencing space (25) by the sound-absorbing hole (26) densely covered by the circumferential surface of the wind chamber (22), and the sound wave will be reduced by the sound-damping member (5〇), thereby greatly reducing the fan operation. The noise generated, the fan will be quite quiet when it is running.
