Abstract
The utility model relates to an air freshener, comprising an outer shell and a wind tunnel core body which is positioned in the outer shell. The wind tunnel core body is provided with a delay circuit device, an electric motor, a fan and an activated carbon air filtration element. The bottom of the outer shell is provided with an air outlet The top of the outer shell is provided with an air inlet. The activated carbon air filtration element is the reticular activated carbon. The reticular activated carbon is arranged on a support frame which is connected with the wind tunnel core body. The outer shell is also provided with a fragrant tab inserting hole. The wind tunnel core body which is corresponding to the fragrant tab inserting hole is provided with a fragrant tab fixing frame. The utility model not only has simple structure, small draft resistance and low energy consumption, but also filters the air and adds the fragrance to the air.
Description
The utility model relates to a kind of air freshener that filters room air.
Existing air freshener comprises shell and the wind-tunnel core body that is arranged in shell, and motor, fan, air filtration element are housed in the wind-tunnel core body, and outer casing bottom has the gas outlet, and cover top portion has air inlet.Therefore described air filtration element adopts the granular pattern activated carbon more, and this air freshener needs special device and fixes the granular pattern activated carbon, and not only its structure is comparatively complicated, and air freshener inner ventilation resistance is big.In addition, another shortcoming of this air freshener is that it only can play the air filtration effect, can't increase fragrance to air.
The purpose of this utility model provides a kind of air freshener, and it is simple in structure, and the inner ventilation resistance is little, and scented tea can be installed increase fragrance to air.
The utility model is achieved in that air freshener comprises shell and the wind-tunnel core body that is arranged in shell, and delay circuit device, motor, fan, activated carbon air filtration element are housed in the wind-tunnel core body, and outer casing bottom has the gas outlet, and cover top portion has air inlet.Described activated carbon air filtration element is netted activated carbon, and netted activated carbon is installed on the bracing frame that links to each other with the wind-tunnel core body, also has the scented tea patchhole on the shell, and on the corresponding wind-tunnel core body of scented tea patchhole a scented tea fixed mount is arranged.At the scented tea insertion scented tea that inserts in the hole, start power supply and make fan running during use, air is by netted active carbon filtration, and the fragrance of scented tea is dispersed in the air simultaneously.Autostop after 90 seconds.
Because it is the air filtration element that the utility model adopts netted activated carbon.Therefore fixing netted activated carbon only needs a bracing frame, thereby it is simple in structure, in addition because designs simplification is reduced the flowing resistance of netted activated carbon and the flowing resistance of its bracing frame.Because the utility model has the scented tea patchhole, so except that filtered air, the utility model can also increase fragrance to air.
The contrast accompanying drawing is described in detail the utility model in conjunction with the embodiments below.
Fig. 1 is the axial cutaway view of an embodiment of the utility model;
Fig. 2 is the circuit diagram of the foregoing description.
Referring to Fig. 1, air freshener comprises shell (6) and is arranged in the wind-tunnel core body (10) of shell (6).Shell (6) relies on tapping screw (2) to be connected with wind-tunnel core body (10).Can add a ring-type sponge (12) between wind-tunnel core body (10) and the shell (6), so both help the air wind-tunnel core body (10) of flowing through in a large number, can alleviate vibrating noise effectively again.Delay circuit device (19), motor (4), fan (11), activated carbon air filtration element are housed in the wind-tunnel core body (10).Fan (11) has flabellum (13), and gas outlet (5) is arranged at shell (6) bottom, and air inlet (17) is arranged at the top.Described activated carbon air filtration element is netted activated carbon (15).Netted activated carbon (15) is installed on the bracing frame (14) that links to each other with wind-tunnel core body (10), and the mode that can stick with glue connects.Motor (4) is installed on the printed circuit board (PCB) (7), and printed circuit board (PCB) (7) is installed on the wind-tunnel core body (10) by screw (1), and delay circuit electric elements (19) can be placed in the space in the wind-tunnel core body (10).Also have scented tea patchhole (9) on the shell (6), and on the corresponding wind-tunnel core body of scented tea patchhole (9) a scented tea fixed mount (18) is arranged.Scented tea fixed mount (18) is the L type, can hold scented tea.In order to realize automatic control, the position that wind-tunnel core body (10) is gone up corresponding scented tea stator (18) is equipped with microswitch (8), and after scented tea (not drawing among the figure) inserted scented tea patchhole (9), automatically starting motor (4) was worked like this.Behind starter motor, delay circuit (19) is worked simultaneously, and motor (4) is out of service automatically after 90 seconds.The central authorities of bracing frame (14) can make a hole (16), for the usefulness of flower arrangement.Label 3 is the power supply reed among Fig. 1.
The delay function of present embodiment is with electric capacity, resistance and Darlington compound transistor, and voltage driving mode is realized, can stop machine operation after 90 seconds, reaches the purpose that reduces energy resource consumption.Electrical schematic diagram is seen Fig. 2.
Claims (2)
1, air freshener, comprise shell and the wind-tunnel core body that is arranged in shell, delay circuit device, motor, fan, activated carbon air filtration element are housed in the wind-tunnel core body, outer casing bottom has the gas outlet, cover top portion has air inlet, it is characterized in that: described activated carbon air filtration element is netted activated carbon, and netted activated carbon is installed on the bracing frame that links to each other with the wind-tunnel core body, also have the scented tea patchhole on the shell, and on the corresponding wind-tunnel core body of scented tea patchhole a scented tea fixed mount is arranged.
2, air freshener according to claim 1 is characterized in that: the position of corresponding scented tea fixed mount is equipped with microswitch on the wind-tunnel core body.
