In an embodiment of the present invention, referring to fig. 2 to 4, the sealing element 5 is installed at the free end of the second connecting portion 23, and when the first housing 1 is installed on the second housing 2, the sealing element 5 is abutted against the end of the first connecting portion 12 facing the air outlet 11, so that the gas inside the two housings can not be discharged to the outside along the gap where the two housings are connected. Of course, the sealing member 5 may be mounted on the end of the first connecting portion 12 facing the outlet 11, but is not limited thereto. In the utility model discloses a another embodiment, sealing member 5 also can be installed in the outer wall of second connecting portion 23, and when first casing 1 was installed on second casing 2, sealing member 5 supported in the inner wall of first connecting portion 12, also can reach with above-mentioned equal sealed effect, no longer gives details here.

The embodiment of the utility model provides a sealing member 5 can be selected to use rubber, silica gel, plastic or other arbitrary elastic material preparation that can be used as sealed.

In order to prevent the first housing 1 and the second housing 2 from being separated after being mounted, in an embodiment of the present invention, referring to fig. 3 to 5, a protrusion 231 is disposed on an outer wall of the second connecting portion 23, and a groove 121 is disposed on an inner wall of the first connecting member 12 and corresponding to the protrusion 231. When the second housing 2 is mounted on the first housing 1, each protrusion 231 is engaged with the corresponding groove 121, so as to effectively prevent the second housing 2 from being separated from the first housing 1.

In order to further fix the first casing 1 and the second casing 2, the present invention provides a blower for conveniently cleaning an impeller, further comprising at least one fixing member 6 penetrating through the first connecting portion 12 and the second connecting portion 23. The fixing member 6 is configured to prevent the first housing 1 from being detached from the second housing 2 when the first housing 1 is mounted to the second housing 2. Referring to fig. 2, at least one insertion hole penetrating the wall thickness of the first housing 1 is formed in the area of the first connection portion 12 of the first housing 1, and a connection hole matched with the insertion hole is formed in the second connection portion 23 corresponding to the insertion hole of the first connection portion 12. A fixing member 6 penetrates through an insertion hole and a connection hole corresponding to the insertion hole to fix the first casing 1 and the second casing 2 to prevent the first casing and the second casing from being loosened or separated from each other. The fixing member 6 may include a screw or a latch, but is not limited thereto.

Referring to fig. 1 to 4, at least one first positioning element 13 having the same extending direction and the same extending length as the first connecting portion 12 is disposed on the inner wall of the first connecting portion 12. The outer wall of the second connecting portion 23 is provided with a second positioning element 24 corresponding to the first positioning element 13, and the second positioning element has the same extending direction as the second connecting portion 23 and the same extending length.

In an embodiment of the present invention, the first positioning element 13 is a sliding slot, and the second positioning element 24 is a sliding block slidably connected to the sliding slot. The chute is opened on the inner wall of the first connecting portion 12, and extends from the opening end of the first connecting portion 12 to the end thereof facing the air outlet 11. The slider is disposed on an outer wall of the second connecting portion 23 and extends from an opening end of the second connecting portion 23 to an end thereof facing the air inlet 21. The cooperation of slider and spout has played the effect of direction on the one hand for second casing 2 installs in first casing 1 more smoothly. On the other hand, because the sliding block and the sliding groove are in clamping fit with each other, the contact area between the first connecting portion 12 and the second connecting portion 23 is greatly increased, so that the connection between the first shell 1 and the second shell 2 is firmer.

Referring to fig. 2 and 6, the driving device of the present invention includes a motor 3, the motor 3 includes a base 33 installed in the first casing 1, a motor body 31 installed on the base 33, and an output shaft 32 connected to the motor body 31 in a driving manner. In one embodiment, the base 33 is fixed to the inner wall of the first housing 1 by screws. The motor body 31 may also be fixedly mounted on the base 33 by screws. Of course, the base 33 may be mounted on the inner wall of the first casing 1 by welding or other methods, and the bottom of the motor body 31 may be mounted on the base 33 by inserting or other methods, which is not limited thereto.

The free end of the output shaft 32 extends into the second housing 2 and is directed towards the air inlet 21. The free end of the output shaft 32 is drivingly connected to an impeller 4. The impeller 4 is configured to continuously supply external air into the accommodating chamber formed by the first casing 1 and the second casing 2 through the air inlet 21. The impeller 4 includes a disk 41 fitted over the free end of the output shaft 32 and at least two blades 42 spaced apart along the circumferential side of the disk 41. In an embodiment of the present invention, referring to fig. 2, the inner wall of the wheel disc 41 is provided with an internal thread, the free end of the output shaft 32 is provided with an external thread, and the wheel disc 41 is rotated to screw into the free end of the output shaft 32. In order to further strengthen the fixing of the wheel disc 41 and the output shaft 32, a bolt or other fixing parts are additionally arranged in the area where the wheel disc and the output shaft are fixed, so that the probability that the impeller 4 falls off from the output shaft 32 in the rotating process can be effectively reduced. The number of the additional blades 42 may be three, four, or five, but is not limited thereto.

In one embodiment of the present invention, the air inlet 21 is provided with an impeller shield 22 opposite to the impeller 4. The addition of the impeller protection cover 22 on the one hand prevents a worker from accidentally inserting a finger into the air inlet 21 during operation, and thus touching the rotating impeller 4, which may cause unnecessary injuries. On the other hand, it can also effectively block the relatively large impurities in the air, such as cotton wool, leaves, etc., from entering the accommodating cavity formed by the first casing 1 and the second casing 2 from the air inlet 21.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. The invention is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
