Referring to fig. 1 to 5, the ventilation therapy device (not shown) of the present invention has a blower 100, wherein the blower 100 includes a volute 10, an impeller 20, and a motor 30 for driving the impeller 20 to rotate. The volute 10 is internally provided with an accommodating space 10a for accommodating the impeller 20, the motor 30 is positioned outside the volute 10, an output end of the motor 30 extends into the accommodating space 10a and is connected with the impeller 20, the volute 10 is provided with a plurality of heat dissipation holes 10b, the heat dissipation holes 10b are positioned on one side of the volute 10 facing the motor 30, and the heat dissipation holes 10b are communicated with the accommodating space 10 a. Specifically, the housing of the motor 30 is provided with a guide groove 30a, and the guide groove 30a corresponds to the heat dissipation hole 10 b; more specifically, the direction outside-in that the guide way 30a is close to the spiral case 10 and faces one side of motor 30 inclines towards, consequently when motor 30 drives impeller 20 pivoted, the produced heat of motor 30 itself is taken away more comprehensively along the fore-and-aft direction of motor 30 behind the guiding action of guide way 30a behind the gaseous meeting of accommodation space 10a through louvre 10b, so make the utility model discloses a fan 100's radiating effect is stronger. More specifically, the following:

with continued reference to fig. 1 to 5, a side of the scroll casing 10 facing the motor 30 is recessed to form a recessed portion 11 for a portion of the motor 30 to protrude into. The output end of the motor 30 passes through the recess 11 and is connected to the impeller 20, and a gap 301 between the housing of the motor 30 and the recess 11 communicates the guide groove 30a with the outside. Preferably, the heat dissipation hole 10b is located at the portion of the recessed portion 11 facing the impeller 20, the portion is located between the impeller 20 and the housing of the motor 30, and the shape of the recessed portion 11 matches the shape of the housing of the motor 30, the side of the motor 30 where the guide groove 30a is opened extends into the recessed portion 11, the guide groove 30a is communicated with the heat dissipation hole 10b, so that the gas in the accommodating space 10a flows outwards by being guided by the guide groove 30a immediately after passing through the heat dissipation hole 10b, and meanwhile, due to the limitation of the side wall of the recessed portion 11, the gas flows along the housing of the motor 30 from the front to the back to take away the heat of the motor 30, so that the heat dissipation structure of the fan 100 of the present invention is skillfully arranged, and the heat inside the motor 30 and the volute 10 can be better conducted away. For example, the outer contour of the cross section of the recess 11 may be set to be an ellipse, a circle, a regular polygon, or the like by those skilled in the art, but is not limited thereto.

With reference to fig. 1 to 5, a first locking hole 11a is further formed on a portion of the recessed portion 11 facing the impeller 20, a second locking hole 30b matched with the first locking hole 11a is formed on a surface of the casing of the motor 30 facing the recessed portion 11, and a locking member sequentially passes through the first locking hole 11a and the second locking hole 30b to lock the motor 30 and the scroll casing 10 together. Therefore, the motor 30 and the recess 11 are detachably locked together by the locking member, so that the connection between the volute 10 and the motor 30 of the fan 100 of the present invention is firmer, and the assembly and disassembly of the volute 10 and the motor 30 are facilitated, but not limited thereto.

With continued reference to fig. 1-5, the volute 10 includes a first housing 12 and a second housing 13. The first housing 12 and the second housing 13 together form an accommodating space 10a, and the recess 11 is opened on the second housing 13. Specifically, a first fixing portion 121 is disposed on the first housing 12, a second fixing portion 131 matched with the first fixing portion 121 is disposed on the second housing 13, and the first housing 12 and the second housing 13 are connected through the first fixing portion 121 and the second fixing portion 131; for example, the first fixing portion 121 may be a male buckle, and the second fixing portion 131 may be a female buckle, so that the first housing 12 and the second housing 13 can be connected by mutually buckling the male buckle and the female buckle; in addition, the first fixing portion 121 and the second fixing portion 131 may be respectively provided with screw holes, and a screw (not shown) sequentially passes through the first fixing portion 121 and the second fixing portion 131 to detachably connect the first housing 12 and the second housing 13. Because the volute 10 is formed by connecting the first shell 12 and the second shell 13, the volute 10 is convenient to disassemble, assemble, transport and store, and the disassembly of the volute 10 and the cleaning of the interior of the volute are also facilitated.

As shown in fig. 1, the volute casing 10 is provided with an air inlet 101 and an air outlet 102, when the motor 30 drives the impeller 20 to rotate, the air pressure in the accommodating space 10a increases, and a portion of the air flow is discharged from the air outlet 102, and since the second casing 13 is provided with a plurality of heat dissipation holes 10b, another portion of the air flow is discharged from the heat dissipation holes 10b and moves along the gap 301, thereby achieving heat dissipation of the motor 30.

Compared with the prior art, because the utility model discloses a seted up a plurality of louvre 10b on spiral case 10, and louvre 10b is linked together with accommodation space 10 a. Therefore work as the utility model discloses a fan is when work, and motor 30 drives impeller 20 in accommodation space 10a internal rotation and produces the wind pressure, because the pressure in accommodation space 10a is greater than the outer pressure of accommodation space 10a this moment, so the air in accommodation space 10a can blow off towards accommodation space 10a through louvre 10b, again because this louvre 10b is located spiral case 10 in the face of one side of motor 30, consequently the air that blows off through louvre 10b can blow towards motor 30, and then has accelerated motor 30's heat dissipation, the utility model discloses a wind pressure that has utilized production in the fan working process ingeniously has realized in time dispelling the heat to fan itself, and then makes the utility model discloses a fan 100's life can prolong.

The above disclosure is only a preferred embodiment of the present invention, and the function is to facilitate the understanding and implementation of the present invention, which is not to be construed as limiting the scope of the present invention, and therefore, the present invention is not limited to the claims.
