A kind of pure type humidifier
Technical field:
The utility model is a kind of pure type humidifier, belongs to the renovation technique of pure type humidifier.
Background technology:
Existing known pure type humidifier is when water evaporates in the water tank, and wind wheel just quits work immediately, thereby the water that is adsorbed on the filter screen can not get evaporating timely, so that filter screen is for a long time under the moistening environment, thereby has promoted growing of bacterium; And badly influence the service life of filter screen.
The utility model content:
The purpose of this utility model is to consider the problems referred to above and a kind of antibacterial ability that increases filter screen is provided, the pure type humidifier that prolongs the service life of filter screen.The utility model is reasonable in design, and is convenient and practical.
The technical solution of the utility model is: include housing, be arranged at water tank and vaporising device in the housing, wherein vaporising device includes wind wheel and filter screen, the sidewall of housing is provided with the steam outlet, the air outlet of wind wheel is corresponding with the position of steam outlet, filter screen places between the air outlet of steam outlet and wind wheel, also be equiped with in its middle shell and realize the air-dry lack of water automatic outage delay device of filter screen, it comprises tongue tube, magnet, float, tongue tube is fixed in the top of magnet, magnet cartridge is located at the top of float, the bottom of float is communicated with the following water valve of water tank bottom by tank, the drive motors of wind wheel is connected on the circuit that tongue tube makes it during with the magnet adhesive with power supply is communicated with, and this circuit is provided with the automatic outage delay circuit.
Above-mentioned tongue tube places on the water tank bottom plate of magnet top.
Above-mentioned filter screen is a ceramic filter screen.
The utility model is owing to adopt the structure that also is equiped with the lack of water automatic outage delay device of realizing that filter screen is air-dry in housing, therefore, when the utility model can the water in water tank evaporates, wind wheel can work on and quit work after a period of time again, thereby make wet ceramic filter screen air-dry, increased the life-span and the filter screen anti-microbial property of filter screen, the utility model is a kind of simple in structure, pure type humidifier reasonable in design, convenient and practical.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include housing 10, be arranged at water tank 1 and vaporising device in the housing 10, wherein vaporising device includes wind wheel 7 and filter screen 9, the sidewall of housing 10 is provided with steam outlet 8, the air outlet of wind wheel 7 is corresponding with the position of steam outlet 8, filter screen 9 places between the air outlet of steam outlet 8 and wind wheel 7, also be equiped with in its middle shell 10 and realize the air-dry lack of water automatic outage delay device of filter screen, it comprises tongue tube 2, magnet 3, float 4, tongue tube 2 is fixed in the top of magnet 3, magnet 3 is installed in the top of float 4, the bottom of float 4 is communicated with the following water valve 5 of water tank 1 bottom by tank 6, the drive motors of wind wheel 7 is connected on the circuit that dried bomb tube 2 makes it during with magnet 3 adhesives with power supply is communicated with, and this circuit is provided with the automatic outage delay circuit.In the present embodiment, the automatic outage delay circuit adopts existing general automatic outage delay circuit, and this delay circuit can be delayed time and be disconnected in 30 minutes again, because of the automatic outage delay circuit belongs to prior art, here no longer describes in detail.Above-mentioned tongue tube 2 places on water tank 1 base plate of magnet 3 tops.Above-mentioned filter screen 9 is a ceramic filter screen 9.
Operation principle of the present utility model is: when water evaporates in the water tank 1, the float 4 that is communicated to water tank 1 by tank 6 drops to extreme lower position, thereby tongue tube 2 shell fragments of magnet 3 on the float 4 and water tank bottom plate are disconnected, because circuit has the delay power down function, wind wheel 7 will work on and stop after a period of time again, thereby realize making the air-dry purpose of wet ceramic filter screen 9.
