Also referring to Fig. 1 and Fig. 2, Fig. 1 is the structural exploded view for the ceiling mounting type fan that the embodiment of the present invention 1 provides, Fig. 2 is the structural schematic diagram of ceiling mounting type fan described in Fig. 1.

As shown in Figure 1, the ceiling mounting type fan includes fan main body 10, bracket 20 and bipolar alternately ion generator 30。

The fan main body 10 includes main shaft 11 and flabellum 12, and the flabellum 12 is located at the circumferential direction of described 11 one end of main shaft On side, and the flabellum 12 is arranged perpendicular to the main shaft 11.The flabellum 12 can be rotated around the main shaft 11.

The main shaft 11 is arranged in close to one end of the flabellum 12 in the bracket 20, and the bracket 20 is located at the fan The downside of leaf 12.

The bipolar alternately ion generator 30 is arranged on the bracket 20, and the bipolar alternately ion generator 30 wraps Ion piece 31 is included, the ion piece 31 is arranged by the bracket 20 in 12 downside of flabellum, and the ion piece 31 is used for It generates bipolar ion and the substance in indoor gas is decomposed.The flabellum 12 stirs room air formation by rotation Air stream, the ion piece 31 alternately produce bipolar ion by being powered, will when the air stream passes through the ion piece 31 The bipolar ion of the generation takes indoor each corner to, using the effects of the chemistry of bipolar ion, physics come to air into Row degerming, deodorization, to provide good, clean environment for people.Further, ion piece 31 sequentially by ground connection pole plate, Dielectric impedance plate and porous transmitting pole plate overlapping composition.Ion generator can produce a large amount of non-equilibrium positive negative oxygen ions, just It can make the charged sedimentation of floating particle object in air under the action of anion, can also be decomposed by a series of physical chemical action The microorganisms such as the bacterium in volatile organic matter and kill air, to carry out degerming, deodorization to the air in automobile.

Above-described embodiment makes the ion piece with institute by the way that ion piece is arranged on the downside of the flabellum of the fan main body Flabellum is stated around the main axis of the fan main body.The flabellum stirs room air by rotation, on the downside of the flabellum Form air stream.Since the ion piece is located on the downside of the flabellum, when the air stream of the formation passes through the ion piece, The bipolar ion that the ion piece generates is taken out of, to discharge the bipolar ion to indoor each corner.It is described bipolar Ion is by way of sharply being collided and being reacted with bacterium, microorganism, virus, the pernicious gas etc. in room air The gaseous pollutant in room air is actively cleaned, builds a healthy environment to user.

In the present embodiment, the bracket 20 can be rotated around the main shaft 11 and is fixedly installed with the flabellum 12.It is described Bracket 20 include be set on the main shaft 11 and can around the first support 21 that the main shaft 11 rotates and with first support 21 With the second support 22 that merging is arranged on the flabellum 12, there is first interface 211 on the lateral surface of the first support 21, There is second interface 221, the both ends of the ion piece 31 are inserted in 211 He of first interface respectively in the second support 22 The second interface 221, so that the ion piece 31 can be rotated with the flabellum 12 around the main shaft 11.Assuming that when described When flabellum 12 is mounted in the fan main body 10, the 12 length extending direction of flabellum is first direction A, then described first connects The opening direction of mouth 211 is consistent with the first direction A；The opening side for the second interface 221 being arranged in the second support 22 The opposite direction of first direction A described in Xiang Zeyu is consistent.The both ends of the ion piece 31 respectively with the first interface 211 and institute The connection of second interface 221 is stated, the ion piece 31 is fixed on the flabellum 12 along the 12 length extending direction of flabellum Downside.

In the present embodiment, the connection of connection ring 40 is provided on the main shaft 11, be provided in the first support 21 with The fixing piece 23 that the connection ring 40 cooperates, the bracket 20 are set on the main shaft 11 by the connection ring 40 and can be around The main shaft 11 rotates.In some specific embodiments, the fixing piece 23 along the first support 21 central axis Line is arranged and is fixed in the first support 21, and the connection ring 40 includes fixed part 41 and rotation section 42, described solid Determine portion 41 to be fixedly mounted on the main shaft 11, the rotation section 42 is fixed on described by matching with the fixing piece 23 On one bracket 21.The rotation section 42 can be moved relative to the fixed part 41, can be made by the rotation rotation section 42 described First support 21 is rotated with the flabellum 12 of the fan main body 10 around the main shaft 11 of the fan main body 10.

In the present embodiment, the bipolar alternately ion generator 30 further includes first that the promising ion piece 31 is powered Power supply 32, the first support 21 are additionally provided with a hollow cavity, and first power supply 32 is along in the first support 21 Side is set in the hollow cavity, and makes the institute the first power supply 32 and be arranged on 21 lateral surface of first support It is corresponding to state first interface 211, in order to which the ion piece 31 connect energization with first power supply 32.

Further, the connection ring 40 has a conducting function, first power supply 32 in the fan main body 10 It is connected and is powered by the connection ring 40 with conducting function between power supply, to power to first power supply 32.Described The electrotransformation obtained from the power supply of the fan main body 10 is High Level AC Voltage by one power supply 32, to provide to the ion piece 31 High Level AC Voltage, so that the ion piece 31 alternately produces bipolar ion after being passed through High Level AC Voltage.

On the one hand power supply in the fan main body 10 is connected to described the using the connection ring 40 by above-described embodiment In one power supply 32, the fan main body 10 and the bipolar line replaced between ion generator 30 when can be to avoid fan work Road is intertwined, and guarantees safety when fan work.It on the other hand is described by using individual high-voltage ac power Ion piece 31 is powered, and the ion piece 31 can be made more efficiently to generate bipolar ion, to more effectively remove indoor Gaseous pollutant.

It is the schematic cross-section in ceiling mounting type fan described in Fig. 2 at 1-1 also referring to Fig. 3, Fig. 3.

As shown in figure 3, in some embodiments, the flabellum 12 in the fan main body 10 include the first blade 121 with And second blade 122, one is spliced to form between first blade 121 and second blade 122, wherein described first For blade 121 for keeping out the wind, second blade 122 is used for wind turning.Using the first plane B vertical with 11 axis of main shaft as base Standard, first blade 121 and second blade 122 are obliquely installed, and the inclined angle of first blade 121 with The angle of second blade lean is unequal.For example, on the basis of the first plane B vertical with 11 axis of main shaft, institute It states corresponding with the first inclination angle a, 122 institute of the second blade between 121 place plane of the first blade and the first plane B It is corresponding between plane and the first plane B that there is the second inclination angle b, the 121 place plane of the first blade and described the It is corresponding with angle c close to 31 side of ion piece between two blades, 122 place plane.The first inclination angle a, described The size of two inclination angle b and the angle c can be set according to the rotation speed of the flabellum 12.Wherein, described first inclines Oblique angle a is less than the second inclination angle b, and the angle c is set as obtuse angle.

In the present embodiment, the ion piece 31 is fixed on institute by the first support 21 and the second support 22 The inside of the second blade 122 is stated, and 31 place plane of the ion piece is not overlapped with the 122 place plane of the second blade.?
