DETAILED DESCRIPTION

[0039] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0040] As Figures 1-11 shown, the utility model includes a kind of air purification function's ceiling fan, including ceiling fan body 1 and being located at the air purification mechanism 2 of ceiling fan body 1 bottom, the ceiling fan body 1 includes outer rotor motor 10, several fan blades 3 and hanging assembly 4, the outer rotor motor 10 includes rotor assembly 11 and stator assembly 12, the hanging assembly 4 one end is connected with stator assembly 12, other end is connected with ceiling, several the fan blade 3 is connected with rotor assembly 11, the hanging assembly 4 includes the hanging bracket 40 being connected with ceiling and the hanging rod 41 for connecting hanging bracket 40 and stator assembly 12, further include the upper cup 42 for covering hanging bracket 40 being connected with hanging bracket 40.The air purification mechanism 2 includes with stator assembly 12 lower part connection for purifying air purification chamber 20, the windward surface on the blade root of each described fan blade 3 is equipped with the air inlet 30 being connected with purification chamber 20, the bottom of the purification chamber 20 and / or the bottom side of the purification chamber 20 is formed with the air outlet 21 that the gas after purification is discharged to the below of fan blade 3 so that fan blade 3 will disturb the gas of discharge.In the present application, preferably, air outlet 21 is arranged in the bottom side of purification chamber 20.

[0041] The purification chamber 20 is also provided with fan 22 for facilitating the air before purification into the purification chamber 20 and the air after purification is discharged.

[0042] In the present application, the air purification mechanism 2 is combined with the ceiling fan, and the air inlet 30 of the purification cavity 20 is arranged on the windward surface of the blade root of the fan blade 3. When the ceiling fan is started, air is filled into the purification cavity 20 from the air inlet 30 for purification, and after purification, the air is discharged to the lower side of the fan blade 3 through the air outlet 21. The purified air is disturbed by the ceiling fan to realize whole house circulation and improve the purification efficiency. By arranging the air inlet 30 on the windward surface of the fan blade 3, the fan blade 3 itself can fill air into the purification cavity 20 to realize air purification. Compared with the previous negative pressure extraction mode by the fan 22, the energy consumption and production cost can be reduced. At the same time, since the fan 22 is omitted, the weight of the whole product can be reduced.

[0043] Since the fan blade 3 is always rotating, the air inlet 30 is not easy to accumulate dust, and the air inlet 30 is far away from the air outlet 21, so that the purified air cannot flow back to the air inlet 30.

[0044] Of course, the fan 22 can also be arranged in the purification cavity 20 to further draw air into the purification cavity 20 for purification, discharge the purified air, increase the air intake, and blow the purified air to the lower side of the fan blade 3 to realize whole house circulation of the purified air.

[0045] After the fan 22 is arranged, the air can be purified even if the ceiling fan is not started, which is more in line with the use of consumers.

[0046] In addition, the air inlet 30 is arranged on the windward surface of the fan blade 3, and the windward surface of the fan blade 3 generally faces the ground, so that air supply can be realized when the fan blade 3 rotates, and dust is not easy to accumulate at the air inlet 30.

[0047] As shown in Figure 11 As a further scheme of the present embodiment, the angle a between the windward surface of the blade root of the fan blade 3 and the horizontal plane is 90°≤a<180°. The angle a between the windward surface of the blade root and the horizontal plane is greater than or equal to 90° and less than 180°, so that dust does not fall to the air inlet 30, and the cleaning frequency can be reduced.

[0048] As shown in Figures 6 to 11As shown, as a further aspect of the present embodiment, the purification cavity 20 is composed of a cavity shell 23 arranged at the lower part of the stator assembly 12, a filter core 24 arranged in the cavity shell 23, and a cavity cover 25 connected with the bottom of the cavity shell 23, the cavity shell 23 and the cavity cover 25 form a filtering cavity 26, a plurality of through holes 27 are formed around the cavity shell 23 and communicate with the air inlet 30 and the filtering cavity 26, the filter core 24 is vertically arranged in the filtering cavity 26 in a cylindrical shape, the air outlet 21 is arranged on the cavity cover 25, and the fan 22 is arranged at the middle part of the filter core 24 and connected with the top of the filtering cavity 26. The filter core 24 comprises at least one of a negative ion dust removal filter screen 240, an aldehyde removal filter screen 241, and a deodorization filter screen 242. In the present embodiment, the filter core 24 comprises the negative ion dust removal filter screen 240, the aldehyde removal filter screen 241, and the deodorization filter screen 242 arranged in sequence from outside to inside, so that the functions of dust removal, aldehyde removal, and deodorization can be realized. It should be further noted that the through holes 27 communicate with the air inlets 30 of the fan blades 3, and when the fan blades 3 are started, air flows from the air inlets 30 to the through holes 27 and then enters the filtering cavity 26. Since air is continuously filled from the air inlets 30, the pressure at the through holes 27 is greater than the pressure in the filtering cavity 26. Therefore, in the case that the fan 22 is not started, gas can also flow to the filtering cavity 26 for filtration and discharge of the filtered gas.

[0049] As shown in Figure 8 , Figure 9 As a further aspect of the present embodiment, the upper part of the edge of the cavity cover 25 extends inwardly and has a limiting part 250 which is sealingly matched with the bottom of the filter core 24. By arranging the limiting part 250 to match with the bottom of the filter core 24, the filter core 24 does not directly match with the bottom of the cavity cover 25, and the purified air can be diffused outwardly, so that the fan blades 3 can disturb the purified air. Further, the bottom side of the cavity cover 25 extends to the bottom of the root of the fan blades 3. In this way, the purified air can be prevented from flowing back to the channel from the gap between the cavity cover 25 and the fan blades 3, and the air can be hindered to some extent, so that the air entering from the air inlets 30 can be prevented from flowing away from the gap between the fan blades 3 and the cavity cover 25. In order to achieve better sealing effect, the joint between the adjacent fan blades 3 can be arranged in a tightly connected manner.

[0050] In the present embodiment, in order to facilitate replacement and installation of the filter core 24, the cavity cover 25 and the cavity shell 23 are connected in a threaded connection manner. Since the filter core 24 is in a cylindrical shape, when installed, the filter core 24 is directly placed on the limiting part 250 of the cavity cover 25, and then rotated to be aligned with the cavity shell 23, so that the installation is completed. In order to enhance the sealing performance, sealing rings can be arranged at the upper and lower ends of the filter core 24. The sealing rings are not shown in the present application. After the cavity cover 25 is fixed, the upper and lower ends of the filter core 24 can be sealingly connected with the limiting part 250 and the inner top of the cavity shell 23 through the sealing rings.

[0051] In addition, in order to make the flow rate of the purified gas flowing out of the air outlet 21 faster, and make the purified gas be disturbed by the fan blade 3, the air outlet 21 is gradually reduced from inside to outside, and the air outlet 21 is inclined to the lower area of the fan blade 3. In this way, the purified air can be blown to the lower area of the rear section of the fan blade 3. The purified air is made to flow quickly.

[0052] As shown in Figure 3 , as a further scheme of the embodiment, the air inlet 30 is detachably provided with a dust screen 31. By setting the dust screen 31, most of the dust can be filtered in advance, and mosquitoes and other insects can also be prevented from entering the air inlet 30.

[0053] As shown in Figure 6 , Figure 7 , as a further scheme of the embodiment, the filter element 24 and the cavity shell 23 form a first sterilization cavity 5, and the first sterilization cavity 5 is provided with a first sterilization assembly 50. The middle part of the filter element 24 forms a second sterilization cavity 51, and the second sterilization cavity 51 is provided with a second sterilization assembly 52. In this embodiment, the first sterilization assembly 50 can be used to sterilize the air before purification, and can prevent bacteria from remaining in the filter element 24. The second sterilization cavity 51 is formed in the middle part of the filter element 24, and the second sterilization assembly 52 is used for re-sterilization, which further improves the sterilization effect. It should be noted that the first sterilization assembly 50 and the second sterilization assembly 52 can be ultraviolet lamps, or ozone sterilization can be used.
