Description

New fan

Technical Field

The utility model relates to the technical field of new fans, in particular to a new fan.

Background

The fresh air blower is an effective air purifying device, which can circulate indoor air, on one hand, the indoor polluted air is discharged out of the room, and on the other hand, the outdoor fresh air is input into the room after the measures of sterilization, disinfection, filtration and the like, so that the room is fresh and clean at all times.

The new fan uses new trend convection technique, through independently supplying air and induced air, makes indoor air realize convection current to furthest carries out indoor air replacement, and the built-in multi-functional clean system of new fan guarantees that the air that gets into indoor is clean healthy.

The existing fresh air fan generally adopts a closed structure, but because the fresh air fan is generally provided with a pre-coarse filter, dust and impurities on the coarse filter are the most, and certain blockage can be caused after long-time use, so that the air purification efficiency is reduced.

Disclosure of Invention

The utility model aims to provide a fresh air machine which is convenient for cleaning a coarse filter.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides a new fan, includes the casing, is provided with air intake and air outlet on the casing, is located air intake one side in the casing and is provided with coarse filtration ware, and casing one side is provided with the slot, all is provided with a plurality of elastic component on the inner wall around being located the slot in the casing, and the centre gripping is fixed with a U-shaped plug-in rail between the elastic component, and coarse filtration ware is pegged graft in the U-shaped plug-in rail, is provided with cam mechanism in the casing, and cam mechanism contradicts on the U-shaped plug-in rail.

Further provided is that: the cam structure is disposed behind the relatively coarse filter.

Further provided is that: the U-shaped plug-in rail is provided with an extension block, and the cam mechanism is abutted against the extension block.

Further provided is that: the coarse filter comprises a frame, an elastic piece is arranged on the inner wall of the shell opposite to the other side of the slot, a strip-shaped sealing plate is rotatably arranged at the upper end of the slot, and a fixing device is arranged at the lower end of the sealing plate.

Further provided is that: the fixing device comprises a door lock.

Further provided is that: the fixing device comprises a hook body arranged below the sealing plate, and a rotating sheet capable of rotating to the hook body is arranged on one side of the shell.

In summary, the utility model has the following beneficial effects: through cam mechanism's effect, can vibrate the coarse filter of too much impurity of adhesion to make most impurity can be shaken off, and then keep fresh air machine's smooth and easy ventilation.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

Embodiment one: a new fan comprises a shell 1, wherein an air inlet 2 and an air outlet 3 are arranged on the shell 1, and a coarse filter 4 is arranged in the shell 1 near the air inlet 2.

One side of the shell 1 is provided with a slot 5, the front and rear inner walls of the slot 5 are provided with a plurality of elastic pieces 6, and the elastic pieces 6 can adopt compression springs. A U-shaped plugging rail 7 is arranged between the front compression spring and the rear compression spring, and the coarse filter 4 is plugged into the U-shaped plugging rail 7 from the upper end and the lower end.

A cam mechanism 8 is provided on the housing 1 behind the coarse filter 4, the cam mechanism 8 comprising a motor and a cam. The U-shaped plug-in rail 7 is provided with an extension block 9, the cam mechanism 8 is abutted against the extension block 9, and the motor can be outwards connected with a switch arranged on the shell 1 through a circuit to realize the purpose of manually switching the motor, or can be set to be started at fixed time and periodically switching the motor.

When the motor starts, the cam mechanism 8 operates, and the cam knocks the extension block 9, so that impurities filtered in the rough filtration process are knocked down, and the rough filtration filter is guaranteed to maintain ventilation efficiency to a certain extent. The front part of the rough filter on the shell 1 can be provided with a strip-shaped groove, so that impurities can be conveniently contained.

The coarse filter 4 comprises a frame 10, and an elastic member 6 is arranged on the inner wall of the housing 1 opposite to the slot 5, and the elastic member 6 is consistent with the elastic member 6, and can be realized by adopting a compression spring. The upper end of the slot 5 is rotatably provided with a strip-shaped sealing plate 12, and the sealing plate 12 seals the slot 5, so that the coarse filter 4 is prevented from sliding out. The lower end of the sealing plate 12 is provided with a fixing device 13, the fixing device 13 can adopt a door lock 14, and the safety of the fresh air ventilator is ensured after the fresh air ventilator is locked by a key.

Embodiment two: the embodiment is similar to the first embodiment, except that the fixing device 13 is a hook 15 disposed at the lower end of the sealing plate 12, and a rotating plate 16 disposed on the housing 1, and the rotating plate 16 is clamped on the hook 15 after rotating, so as to realize the stability of the sealing plate 12.
