Referring to the drawings, the blower 100 includes a main body 1 and a handle 2, the main body 1 including a main body housing defining a receiving chamber, and an air deflector 144 provided in the main body housing. The main body 1 further comprises a first fluid channel 31, and an air outlet of the first fluid channel 31 is an air outlet 172 of the blower 100. The handle 2 defines a second fluid passageway 32 therein, the inlet port of the second fluid passageway 32 being the inlet port 171 of the blower 100, the outlet port 322 of the second fluid passageway being in fluid communication with the inlet port 311 of the first fluid passageway. The air deflector 144 serves to change the flow direction of the air flow flowing from the second fluid passage 32 into the first fluid passage 31. The air deflector 144 includes a proximal end 147 close to the handle 2 and a distal end 145 far away from the handle 2, along the axial direction of the main body 1, a vertical distance from the distal end 145 to a plane where the air outlet 172 is located is a first distance M1, a vertical distance from the proximal end 147 to the plane where the air outlet 172 is located is a second distance M2, a vertical distance from one end of the air outlet 322 of the second fluid channel far away from the air outlet 172 to the plane where the air outlet 172 is located is a third distance M3, and the third distance M3 is greater than the first distance M1 and less than the second distance M2. The near end and the far end of the air deflector 144 are respectively arranged at two sides of the edge of the air outlet 322 of the second fluid channel, so that the air flow blown out from the air outlet can be ensured to be directly blown onto the air deflector 144, the direction of the air flow can be effectively realized, and the noise generated by the air flow is reduced.

Further, a vertical distance from the end of the air outlet 322 of the second fluid channel, which is close to the air outlet 172, to the plane of the air outlet 172 is a fourth distance M4, and the fourth distance M4 is smaller than the first distance M1. In this way, a sufficient area for the high-speed air flow of the air outlet 172 to pass through can be ensured, and thus, noise can be effectively reduced.

The transition between the distal end 145 of the deflector 144 and the proximal end 147 of the deflector 144 is smooth. The air flow can be effectively guided. Referring to the drawings, the air deflector 144 is configured to protrude toward the direction in which the air outlet 172 is located. The forward convex shape can make the airflow change from the vertical direction to the horizontal direction more quickly. In the case of the rearwardly convex configuration, a very large curvature is required to achieve smooth deflection of the airflow, and in order to make the internal structure of the blower 100 more compact, it is apparent that the internal structure of the blower 100 is not suitable for the air deflector 144 of this shape.

The blower 100 generally has a hot air function, and thus, a heater 15 is required to be provided in the blower 100 to heat the air flow. A heater 15 is provided in the main body casing, and the heater 15 and the air guide 14 together define an inlet 311 of the first fluid passage. In one embodiment, the heating wire 155 may be devoid of the inner tube 152. The heater 15 includes a heating wire 155 and an outer tube 153 disposed on the outer periphery of the heating wire 155, wherein one end of the outer tube 153 contacts the air guide 14, and the two cooperate to form a part of the first fluid channel 31. In order to ensure that the air flow can smoothly enter the first fluid channel 31 and flow in the first fluid channel 31, the air outlet 322 of the second fluid channel faces the air inlet 311 of the first fluid channel, and the projection of the air outlet 322 of the second fluid channel in the vertical direction falls into the range of the air inlet 311 of the first fluid channel. The air guide plate 144 is provided with a connecting wall 146 substantially parallel to the outer tube 153, and after the outer tube 153 contacts the air guide plate 144, part of the outer tube 153 overlaps the connecting wall 146. Thus, the air flows along the outer tube 153 to the air outlet of the blower 100, so that the fluidity of the air is better, and the noise generated by the air flowing in the blower 100 can be reduced.

In another embodiment, the heater 15 includes an inner tube 152, a heating wire 155 disposed at the outer circumference of the inner tube 152, and an outer tube 153 disposed at the outer circumference of the heating wire 155, the inner tube 152, the outer tube 153, and the air guide 14 together defining a portion of the first fluid passage 31. The heater 15 further includes a tubular support, and the inner tube 152 is disposed at an outer periphery of the support. The support of the heating wire 155 can be effectively ensured.

The air guide 14 includes a tubular connection portion 141 and an air guide plate 144 provided on the outer periphery of the connection portion 141. The other end of the connection portion 141 is connected to the inner tube 152. The tubular connection 141 is directly or indirectly connected to the inner tubular body 152 to form part of the inner wall of the first fluid channel 31. The air guide plate 144 is provided with a connecting wall 146 substantially parallel to the outer tube 153, and after the outer tube 153 contacts the air guide plate 144, part of the outer tube 153 overlaps the connecting wall 146. The outer tube 153 forms part of the outer wall of the first fluid channel 31. The outer pipe 153 extends to the air deflector 144, so that the phenomenon that the air flow flowing out of the second fluid channel 32 blows to the main body shell to cause kinetic energy loss can be effectively avoided, and meanwhile, the wind noise can be reduced due to the overlapping between the outer pipe 153 and the air deflector 144.

The inner tube 152 has an outer diameter greater than that of the connection portion 141. In this way, the area of the first fluid passage 31 can be gradually reduced in the direction of the air flow, effectively reducing noise. If the cross-sectional area of the fluid channel decreases suddenly in the direction of the air flow, a loud noise is generated here.

The air guide plate 144 is provided with a connecting wall 146 substantially parallel to the outer tube 153, and after the outer tube 153 contacts the air guide plate 144, part of the outer tube 153 overlaps the connecting wall 146. In this way, most of the air flow can be ensured to circulate in the first fluid channel 31, so that the air flowing out of the first fluid channel 31 between the air deflector 144 and the outer tube 153 is effectively reduced, and the noise is reduced.

A plasma emitter 12 is also provided in the main body 1, and a part of the plasma generator is provided in the connection portion 141. The plasma emitter 12 includes a positive ion discharge end and a negative ion discharge end, which are disposed inside the outer tube 153.
