Abstract

The utility model discloses air purification equipment with a chamfer mark, which comprises an air duct, a filter bracket and a HEPA filter, wherein the filter bracket and the HEPA filter are arranged in the air duct; the HEPA filter is detachable on the filter support, the HEPA filter comprises a rectangular fixing frame and a filter screen, the filter screen is fixedly arranged in the fixing frame, one corner of the fixing frame is provided with a chamfer, and the filter support is provided with a filling inclined plane corresponding to the chamfer of the fixing frame. The HEPA filter has the beneficial effects that the chamfer is arranged at one corner of the fixing frame of the HEPA filter, the filter support is provided with the filling inclined plane corresponding to the chamfer, and the chamfer is matched with the filling inclined plane, so that the HEPA filter has only one installation direction on the filter support, has no reverse installation problem, can not be assembled due to the deviation of the angle and the size of the chamfer, solves the imitation problem, has compact structure fit, and ensures the service performance and the service life of products.

Description

Air purifying equipment with chamfer marks

Technical Field

The utility model relates to the field of air treatment, in particular to air purifying equipment with corner cut marks.

Background

With the improvement of life quality of people and the demands of partial scenes, the application scenes of HEPA filters are more and more wide, such as air treatment equipment of air purifiers, air conditioners, dust collectors and the like. The HEPA filter is a disposable dry type high-efficiency air filter and is made of laminated boron-silicon microfibers, and has the advantages of small wind resistance, large dust holding capacity and high filtering precision. Since the screens of HEPA filters are on opposite sides, special care must be taken not to be taken when installing the HEPA filters into the apparatus or when the consumer is replacing the HEPA filters, otherwise the filtering effect is affected and also the service life of the air treatment apparatus is affected. The existing plate-shaped HEPA filter has no special structure, so that consumers are easy to confuse, even the consumers cannot pay attention to the distinction of the positive aspects, the assembly is easy to reverse, and meanwhile, if the consumers use the HEPA filter with low quality, which is easy to imitate, the filtering effect is also influenced.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provides air purifying equipment with a chamfer mark.

The technical scheme adopted for solving the technical problems is as follows:

an air cleaning device with a chamfer mark comprises an air duct, a filter bracket arranged in the air duct and a HEPA filter; the HEPA filter is detachable on the filter support, the HEPA filter comprises a rectangular fixing frame and a filter screen, the filter screen is fixedly arranged in the fixing frame, one corner of the fixing frame is provided with a chamfer, and the filter support is provided with a filling inclined plane corresponding to the chamfer of the fixing frame.

Preferably, the chamfer is a 45 ° chamfer.

Preferably, the inner wall of one side of the fixed frame extends inwards to form a limit edge.

Preferably, the air purifying device is an air purifier, an air conditioner or a dust collector.

The HEPA filter has the beneficial effects that the chamfer is arranged at one corner of the fixing frame of the HEPA filter, the filter support is provided with the filling inclined plane corresponding to the chamfer, and the chamfer is matched with the filling inclined plane, so that the HEPA filter has only one installation direction on the filter support, has no reverse installation problem, can not be assembled due to the deviation of the angle and the size of the chamfer, solves the imitation problem, has compact structure fit, and ensures the service performance and the service life of products.

The utility model is described in further detail below with reference to the drawings and examples; the air cleaning apparatus with the chamfer marks of the present utility model is not limited to the embodiment.
