Description of the invention: [Technical field to which the invention pertains] (3) The present invention relates to a side-blown fan, and more particularly to a side-blown fan that increases air volume and reduces operating noise. [Prior Art], β In the high-pressure back-pressure system, it is customary to use a blower (Blower), and the wind and the same wind pressure to the system, so that the system obtains a higher back pressure. Moreover: in the conventional blower configuration, because the blower housing - on the side only shape = there is a flaw. The ventilator's and the size of the human vent are smaller than the impeller in the blower. Therefore, when the blower is operating, although it can provide a large wind pressure, the second is accompanied by an increase in the volume of the cymbal, and even the amount of human air is greatly increased. In order to increase the amount of airflow, the above-mentioned Wind 2 is found to be similar in size to the impeller inside the blower. (9) In this case, although the air volume is reduced, the operating wind pressure is relatively reduced, and there is no substantial increase or even a decrease in the wind. SUMMARY OF THE INVENTION Therefore, the present invention provides an intake air amount of a side, ★ blower fan. The _human fan's invention is further provided with a side-blown fan to reduce the running buzzer. In the case of =, the present invention provides a side blow type, which comprises a __ housing having a main air inlet and at least a sub air inlet. The leaf = is placed in the body and includes a hub, a plurality of blades and at least a panel. The vanes surround the hub. The ring plate is connected to the blades, 200923216 and the ring plate shields the auxiliary air inlet. In the above side blower fan, the sub air inlet extends outward from the edge of the main air inlet or is independent of the main air inlet. The main air inlet is in the shape of a circle, an ellipse, a polygon or an irregular shape. The shape of the auxiliary air inlet is a ring shape, a fan shape, a polygon shape, a circular hole, an elliptical hole or a sausage hole. In addition, the ring plate may not obscure the main air inlet. When the number of the ring plates is 2 or more, the ring plates may shield a part of the auxiliary air inlets together or separately. Additionally, the main air inlet may be coaxial with the impeller. When the number of the sub air inlets is two or more, the ring plates may partially or separately shield the plurality of sub air inlets. The blades are flat blades, curved blades, streamlined blades or scroll blades. In the above side blower fan, the housing may be a combination of a first housing and a second housing. At this time, the first housing may have the main air inlet and the auxiliary air inlet, and the second housing may also have another main air inlet. Even the second housing may have another auxiliary air inlet, and the impeller has at least one other annular plate connected to the blades, wherein the other annular plate is a shielding portion of the other auxiliary air inlet . , "Hai another field into the tuyere extends from the edge of the other main air inlet or independent of the other - owner wind σ. The shape of the other person's tuyere may be a ring shape, a ridge shape, a round hole, an elliptical hole or a sausage type hole. The other main incoming air π shape may be circular, elliptical, polygonal or irregular. In addition, the other ring plate may not shield the other main air inlet. When the number of the other ring plates is & 2 or more, the other ring plates may respectively shield part of the other pair of air inlets or 200923216. In the side blower fan of the present invention described above, the amount of intake air of the side blower fan can be increased by the addition of the sub inlet vent. Further, in the side-blown fan of the present invention, the ring plate is further added, and the auxiliary air inlet is shielded from the ring plate to change the flow field change of the auxiliary air inlet, thereby achieving the effect of greatly reducing the running noise. The above and other objects, features and advantages of the present invention will become more apparent and understood. 2, the side-blown fan 1A of the present invention includes a -the first housing 102, a second housing 116, and an impeller 1〇8. The side blower fan can be a blower fan. The first housing 102 has a main air inlet 1〇4 and at least one pair of air inlets K)6. The first housing 1〇2 and the second housing U6 are correspondingly joined to form a housing 118 and form a space 1. The main air inlet 1〇4 shape may be circular, observing, polygonal or irregular. . Preferably, the master tuyere (10) is coaxial with the impeller 108. The sub-inlet vent 106 may extend outward from the edge of the main air inlet 1 〇 4 or may be independent of the main vent 1G4. The shape of the ventilator ι〇6 can be a ring shape, a fan shape, a polygon shape, an elliptical hole or a sausage hole. The number of the sub-inlet vent H)6 can be "solid" or more than two. The impeller (10) is disposed in the accommodating space (that is, disposed in the housing 200923216 118), and the impeller 108 includes a hub portion 11A, a plurality of blades 112, and at least one ring plate 114. The vanes 112 surround the hub. One side of the ring plate 114 is connected to the top ends of the vanes 112, and the ring plate lu covers a portion of the sub air inlet 106. The blades 112 may be flat blades, curved blades, streamlined blades or scroll blades. In addition, the ring plate U4 may not shield the main air inlet 104. Further, the number of the ring plates 114 may be one or two or more. When the number of the ring plates 114 is 2 or more, the plurality of the seed panels 114 may shield the portion of the sub-inlet vents 1 〇 6 together or separately. In the present invention, the main housing and the sub air inlet are formed in the first housing 1〇2 as an example. However, the second housing housing 16 may be formed with a main air inlet. The main air inlet and the air inlet are formed at the same time. The main air inlet and the air inlet of the second housing 116 are the same as the main air inlet 1 and the air inlet 106, and are not described here. In addition, another annular plate may be disposed on the impeller 108 corresponding to the auxiliary air inlet of the second casing 116. The annular plate is identical to the annular plate U4 and will not be described herein. In the side blower fan of the present invention described above, the amount of intake air of the side blower fan can be increased by the addition of the sub inlet vent. In addition, in the side 17-person fan of the present invention, a ring plate is further added, and the pair of air inlets are shielded by the ring plate to change the flow field of the auxiliary air inlet without reducing the flow rate of the main air inlet. Change, and achieve the effect of greatly reducing the operation of π 喿. While the present invention has been described above in terms of a preferred embodiment, it is not intended to limit the invention to any of the skilled artisan, and the various modifications and refinements can be made without departing from the scope of the invention. Therefore, the protection scope of the present invention is defined by the scope of the appended claims.
