The present embodiment discloses a blower, as shown in fig. 1-2, the blower 10 includes a blower drum 100 and a negative ion generating device 200, the negative ion generating device 200 is fixed on the blower drum 100; and the negative ion generating device 200 includes an ion generating unit 210 for generating negative ions, the ion generating unit 210 being accommodated by a high voltage ion chamber 220, an outer wall of the high voltage ion chamber 220 being made of an insulating material; the negative ion generating device 200 is further provided with an ion emitting wire 230, wherein the ion emitting wire 230 is connected with the ion generating unit 210, extends from the inside of the high-voltage ion cavity 220 to the outside of the high-voltage ion cavity 220, and is used for guiding out negative ions generated in the high-voltage ion cavity 220; wherein, the ion generating unit 210 and the ion emitting wire 230 are fixedly connected to the high voltage ion chamber 220, and the high voltage ion chamber 220 is fixed in the air duct 100.

Specifically, the high-voltage ion chamber 220 is integrally fixed inside the air duct 100, the ion generating unit 210 is fixedly disposed in the high-voltage ion chamber 220, and the ion generating unit 210 includes a high-voltage electrode, so that negative ions generated by the ion generating unit 210 are stored in the high-voltage ion chamber 220, and the ion emitting wire 230 has two ends disposed opposite to each other in the length direction, wherein one end is disposed in the high-voltage ion chamber 220 and connected to the ion emitting wire 230. The ion emitting wire 230 extends from the junction with the ion generating unit 210 to the outside of the high voltage ion chamber 220, so that negative ions can be guided out of the high voltage ion chamber 220 through the ion emitting wire 230 and reach the other end of the ion emitting wire 230.

By the arrangement, on one hand, the ion generating unit 210 is arranged in the high-voltage ion cavity 220 in a closed mode, and because the outer wall of the high-voltage ion cavity 220 is made of insulating materials, the high voltage generated by the ion generating unit 210 cannot influence external elements, a user cannot touch the high-voltage electrode in the using process, and the electricity safety is guaranteed; on the other hand, the ion emission wire 230 can lead out the negative ions, so that the negative ions are led out to a more convenient diffusion position without being influenced by the installation position of the negative ion generating device 200, and the diffusion quality of the negative ions is ensured.

With continued reference to fig. 2, the blower 10 has a blower barrel 100 with an air outlet 110 and an air inlet, the high voltage ion chamber 220 is adjacent to the air outlet 110, and the ion emitting leads 230 extend toward the air outlet 110. In the vicinity of the air outlet 110, the blower 10 has relatively few other energizing structures, so that the influence of the high voltage generated by the high voltage electrode in the ion generating unit 210 on other elements can be further avoided, and the ion emitting wire 230 and one end of the ion emitting unit can be conveniently extended to the vicinity of the air outlet 110, so that the negative ions generated by the negative ion generating device 200 can be conveniently propagated.

Further, an end of the ion emitting wire 230 near the air outlet 110 is used as an ion emitting end 231, and a minimum distance from the ion emitting end 231 to the air outlet 110 is greater than or equal to 1 mm and less than or equal to 20 mm. Since the air outlet 110 is not generally a small hole structure, and is generally band-shaped or ring-shaped, so that the air outlet 110 is more sufficient, and in this embodiment, the air outlet 110 is an annular structure surrounding the wall of the air duct 100, so that the minimum distance between the ion emitting end 231 and the air outlet 110, that is, the distance between the ion emitting end 231 and a point closest to the edge of the air outlet 110, is exemplified. In this way, the negative ions generated by the ion generating unit 210 can be led out to the vicinity of the air outlet 110 through the ion emitting wire 230, and reach the surface of the object 600 of the blower 10 together with the air blown out from the air outlet 110. In addition, since a certain distance exists between the ion emission end 231 and the air outlet 110, the minimum distance is greater than or equal to 1 mm, so that the ion emission end 231 is arranged inside the air outlet 110 of the blower 10, and even if a user directly contacts the air outlet 110 with the object 600 to blow air, the ion emission end 231 is not contacted, and dangers such as electric shock of the user are avoided. If the distance is less than 1 mm, even if the ion emitting end 231 extends out of the air outlet 110, it may contact the object 600 during the use of the user, possibly bringing about the danger of electric shock of the object 600, etc., and possibly making the user hear the current sound during the use, thereby affecting the use experience of the user. On the other hand, if the minimum distance is more than 20 mm, negative ions may adhere to the wall surface of the air outlet 110, and thus the minimum distance between the ion emitting end 231 and the air outlet 110 is 20 mm or less, the negative ions can be sufficiently diffused from the air outlet 110 to the object 600 along with the air flow.

The wind barrel 100 includes a wind outlet end wall 120, the wind outlet end wall 120 is in an end-to-end connection structure, and the wind outlet end wall 120 encloses the wind outlet 110 of the wind barrel 100, one end of the ion emitting wire 230, which is close to the wind outlet 110, is taken as an example emitting end, and the periphery of the ion emitting end 231 is surrounded by the wind outlet end wall 120. For example, the air outlet end wall 120 encloses a closed pattern, i.e. the air outlet 110, and the ion emitting end 231 is surrounded by the air outlet end wall 120, so that the ion emitting end 231 is not exposed outside the structure of the blower 10, and the blower 10 is more attractive in appearance, and the ion emitting end 231 is surrounded by the air outlet end wall 120, so that the ion emitting end 231 is not directly contacted with an external structure, electric shock can be further prevented, and electric safety is ensured.

Further, the minimum distance between the ion emitting end 231 and the air outlet end wall 120 is greater than 5mm, and the minimum distance between the ion emitting end 231 and the air outlet end wall 120, that is, the distance between the ion emitting end 231 and the nearest point of the air outlet end wall 120, if the distance is greater than 5mm, negative ions are more easily adhered to the air outlet end wall 120, so as to affect the diffusion effect of the negative ions. Therefore, when the minimum distance between the ion emitting end 231 and the air outlet end wall 120 is greater than 5mm, the diffusion of the negative ions to the object 600 is facilitated.

In this way, since fewer components are energized near the air outlet 110 of the blower 10, the possibility of being affected by the high pressure in the ion generating unit 210 is reduced, and since the other components are attached to the peripheral wall of the air duct 100 more, the radial center is left free, and the installation of the negative ion generating device 200 can be facilitated while avoiding the influence of the high pressure on the other components.

Further, the air duct 100 further includes an air outlet panel 130, the air outlet panel 130 is fixed to one end of the air outlet end wall 120, a gap exists between the air outlet end wall 120 and at least part of the air outlet panel 130, and an air outlet 110 is formed; alternatively, the air outlet panel 130 is provided with a hollow part, the hollow part is used as the air outlet 110, the air outlet panel 130 is recessed from the outer edge to the center to the inside of the air duct 100 to form an inner concave part 131, the top end 1311 of the inner concave part 131 is positioned at the central position of the air outlet end wall 120 along the radial direction, and the negative ion generating device 200 is oriented to the top end 1311 of the inner concave part 131.
