Description of the new type: [Technical field to which the new type belongs] This creation relates to an improved structure of the exhaust fan, especially to a device that can be applied to a range hood or a device that requires exhaust ventilation, and is designed in the air hole of the exhaust fan casing A first air guide ring and a second air guide ring are respectively provided at the corresponding positions on both sides, wherein the extension of the first air guide ring projects outward, and at the same time, the extension of the second air guide ring projects toward the volute bellows. The air inlet on the end face is an improved structure of the exhaust fan which can reduce the air vent clearance and improve the exhaust efficiency. ^ [Previous technology] Exhaust fans are mainly used for various devices that require exhaust air, forced air flow, and heat dissipation, or devices that exhaust internally polluted air to the outside, such as range hoods. Although most of the exhaust fans generally have these basic functions of exhaust air exhaust, many different types of exhaust fans have different shapes and appearances and different exhaust strengths due to different component connections and structural designs. At present, it is known that the above-mentioned exhaust fans for exhaust ventilation are limited by the heat bearing capacity of the motor and are actually strong. The motor is often subject to the high temperature of the work environment and the high temperature of the thief. The motor overheats and quickly fails, or the exhaust fan & method can perform the normal exhaust air exhaust function. In addition, in order to improve the air flow efficiency, the above-mentioned traditional exhaust fans for exhaust air exhaust are mostly outside the fan cover. However, the fan cover and the fan still affect the exhaust effect, which also causes the exhaust fan to fail to perform normal exhaust. One of the reasons for exhaust. [New content] With this, the creator has accumulated many years of design and manufacturing experience, and has developed a first-generation exhaust fan to improve the structure, which can effectively solve the above problems. That is, the main purpose of this creation is to provide an improved structure of the exhaust fan, which is specially supplied for use on range hoods or devices that require exhaust ventilation. The corresponding positions on both sides of the air holes in the shell of the thief machine are designed, and the first- The wind deflector ring and the second air deflector ring, wherein the extension section of the t deflector ring is projected outward, and at the same time, the M281136-wind deflector extension section is projected into the air inlet on the end face of the Erfeng bellows. Improved structure of exhaust fan that can reduce air vent clearance and improve exhaust efficiency. The secondary-purpose of this creation is to provide a kind of retrofitting of the exhaust fan. The design of the fan-shaped bellows motor and the impeller of the recorder are housed inside a casing to separate the motor separately and avoid being affected. The influence of external heat sources can increase the service life of the motor and increase the efficiency of exhaust ventilation. In order to achieve the above purpose, the following technical schemes are adopted in this creation. The preferred embodiment of the present invention is to reduce and improve the structure, which mainly includes a shell part with an upper cover, a scorpion bellows, a first air guide ring, and a second air guide ring. # * The above-mentioned housing part is provided with an air hole on its end surface, and an upper hole of the housing part is also provided with an air hole, and the upper cover can be assembled on the housing part to form a closed space. The worm-shaped bellows are housed in the hollow interior of the shell portion. The end of the bellows-shaped bellows is provided with an air inlet stand, which corresponds to the air hole on the end of the shell portion. An additional air outlet is provided on the worm-shaped bellows. The impeller is provided in the air hole provided in the cover of the housing part; the impeller is provided inside the ant-shaped bellows, and can be driven to rotate by the external motor of the worm-shaped bellows, and the air is sucked in from the air inlet and discharged from the air outlet. In order to achieve the above purpose, the following technical schemes are adopted in this creation. The most important part of this creation is the reduced structure and improved structure, which mainly consists of a combination of a turning section, a volute bellows, a first wind guide ring, and a second wind guide ring. , I- "The upper casing part is provided with an air hole on its end surface, and the upper part of the casing part is also provided with a 盍 that can be assembled on the casing part to form a closed space. 'The' The snail-shaped bellows is accommodated in In the hollow interior of the shell part, the end face of the pot-shaped bellows is set to correspond to the air hole on the end face of the shell part, and the snail-shaped bellows is additionally provided with an air outlet, which can be used to cover the hole H of the upper part of the cover. Lai_ 风 _ 卩, Kona automatically rotates and sucks air from the air inlet and exhausts it from the air outlet. 丨 Motor Lord [Embodiment] M281136 Attached to the-figure, this is a three-dimensional appearance of the improved structure of the extraction fan. Section- The picture is an exploded view of the improved structure of the inserting fan of the creative work. Please ...: As shown in the figure, the housing part 10 of the creative air exhaust 11, the ant-shaped wind box 20, and the cover are formed by the cover.帛 -Wind guide 30, and- Second wind guide ring 40, the set ^ on ^ _G, in her set-New 12, the top cover of the tender * * door.
