Description
Technical Field
The utility model relates to a fresh air ventilator technical field especially relates to a multiple filtration formula fresh air ventilator.
Background
Fresh air ventilator mainly used indoor air's purification can filter the elimination with dust, germ and some peculiar smell in the air to guarantee indoor air quality, and the filter screen of current fresh air ventilator inside is very inconvenient when changing, and the user of not being convenient for changes the filter screen by oneself.
Disclosure of Invention
The utility model aims at solving the defects existing in the prior art and providing a multiple filtration type fresh air ventilator.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a multiple filtration formula fresh air ventilator, which comprises a bod, the protection casing is installed to one side of organism, the opposite side of organism is provided with negative-pressure air fan, and be provided with inlet channel between protection casing and negative-pressure air fan's the inlet end, and inlet channel's top is provided with the slot, the slot interpolation is equipped with the filter, and inlet channel's below is provided with the recess, install the spring in the recess, the spring offsets with the bottom of filter and presses, and one side of slot is provided with the thread fixing piece, the opposite side of slot has the one end of apron through the hinged joint, the other end of apron is fixed on the thread fixing piece through.
Preferably, the two side walls of the filter plate are in sliding fit with the inner wall of the air inlet channel, and the filter screen is arranged in the middle of the filter plate.
Preferably, the filter screen on the filter is the active carbon filter screen, the light touches coal net and HEPA filter screen from the air inlet direction in proper order.
Preferably, the sum of the lengths of the slot and the thread fixing block is the same as the length of the cover plate, and the sealing blocks are fixed at the bottom and the peripheral side wall of the cover plate in a gluing mode.
Preferably, a wire mesh is arranged on the protective cover at a position corresponding to the air inlet channel.
The utility model has the advantages that:
1. indoor gas is sucked into the machine body through the negative pressure fan, the entering air sequentially penetrates through the filter plates in the air inlet channel, and dust particles, peculiar smell and bacteria in the air are filtered through the activated carbon filter screen, the light-contact coal screen and the HEPA filter screen on the filter plates.
2. Make the apron open through rotating hand screw, drive the filter and up lift up under the effect of the restoring force of spring to can take the filter out from the slot, thereby the filter screen to on the filter that can be convenient is changed.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a multiple filtration type fresh air ventilator comprises a ventilator body 1, a protective cover 3 is installed on one side of the ventilator body 1, a wire mesh is arranged on the protective cover 3 at a position corresponding to an air inlet channel 4, a negative pressure fan 2 is arranged on the other side of the ventilator body 1, and the air inlet channel 4 is arranged between the protective cover 3 and the air inlet end of the negative pressure fan 2.
The both sides wall of filter 9 and inlet channel 4's inner wall sliding fit, and the middle part of filter 9 is provided with the filter screen, and the filter screen on the filter 9 is active carbon filter screen, light touch coal net and HEPA filter screen from the air inlet direction in proper order.
In this embodiment, when the fresh air ventilator is used, indoor air is sucked into the machine body 1 through the negative pressure fan 2, and the entering air sequentially passes through the filter 9 in the air inlet channel 4, and through the activated carbon filter screen, the light-touch coal screen and the HEPA filter screen on the filter 9, dust particles, peculiar smell and bacteria in the air are filtered.
Filter screen on filter 9 makes apron 5 open through rotating hand screw 6 after using a period, and under the effect of spring 10's restoring force, spring 10 drives filter 9 and upwards lifts up to can take filter 9 out from slot 7, thereby can be convenient the filter screen to on the filter 9 change.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
