Technical Field
The utility model relates to the technical field of filters, in particular to a fan blade type efficient breathing filter.
Background
The respiratory filter is called artificial nose for short, is a filter used in a respiratory loop, heats and humidifies gas inhaled into a human body, the gas enters an air passage in a warm and humidified state through a respiratory simulator during inhalation, the air passage is ensured to obtain effective and proper humidification, dust is blocked and sterilization is realized, and a good filtering effect is realized
The existing filter has the defects of small filtering area, low filtering rate and large airflow resistance, the whole filter is often widened and inconvenient to install when the filtering area is increased, the airflow resistance is increased when a filter screen is added to increase the filtering rate, and the filter is heavy when the size is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects and provides a fan blade type efficient breathing filter, wherein rotating fan blades accelerate the flow of gas and can filter the gas efficiently.
In order to overcome the defects in the background art, the technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a filter is breathed to fan blade formula high efficiency, includes upper cover and lower cover, the lower cover inlays and establishes into inclosed inner chamber in the upper cover, on cover and be equipped with the sample mouth of pipe and the mouth of pipe of admitting air, cover down and set up the mouth of pipe of giving vent to anger, be equipped with in the inner chamber to cover and close the filter screen of establishing into the lower cover inside with the card at the fan constitution of lower cover opening part.
The further improvement comprises that a step for placing a filter screen is arranged in the lower cover.
The improved fan comprises a cover plate, a support rod and spiral fan blades, wherein the cover plate is rotatably connected with one end of the support rod, the other end of the support rod abuts against the filter screen, and the spiral fan blades are arranged on the support rod.
The further improvement comprises that the spiral fan blade is provided with a nano antibacterial material with an adsorption function.
The further improvement comprises that the outer wall of the lower cover is provided with a wave structure.
The utility model has the beneficial effects that: strengthen when breathing in when admitting air or using, helical structure's fan inertia is gas flow with higher speed to set up the adsorbed layer on the flabellum, high-efficient adsorption filtration, and the mode convenient to detach and the change that upper cover and lower cover card were established.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a cross-sectional view of the present invention;

in the figure, the device comprises an upper cover, a sampling pipe orifice 2, an air inlet pipe orifice 3, an inner cavity 4, a spiral fan blade 5, a filter screen 6, an air outlet pipe orifice 7, a lower cover 8, a step 9, a support rod 10, a cover plate 11 and a fan 12.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to the figures 1 and 2, a fan blade type high-efficiency breathing filter comprises an upper cover 1 and a lower cover 8, wherein the lower cover 8 is embedded in the upper cover 1 to form a closed inner cavity 4, the structure is convenient to install and disassemble, a sampling pipe orifice 2 and an air inlet pipe orifice 3 are arranged on the upper cover 1, an air outlet pipe orifice 7 is arranged on the lower cover 8, a fan assembly 12 covering the opening of the lower cover 8 and a filter screen 6 clamped in the lower cover 8 are arranged in the inner cavity 4, a step 9 for placing the filter screen 6 is arranged in the lower cover 8, the fan assembly 12 comprises a cover plate 11, a support rod 10 and a spiral fan blade 5, the cover plate 11 is rotatably connected with one end of the support rod 10, the other end of the support rod 10 supports against the filter screen 6 and is provided with the spiral fan blade 5, the filter screen 6 is ensured not to be loosened when the spiral fan blade 5 rotates, and a nano antibacterial material with an adsorption function is arranged on the spiral fan blade 5, the outer wall of the lower cover 8 is provided with a wave structure, so that the friction between the upper cover 1 and the lower cover 8 is increased, and the looseness is prevented.
By adopting the above embodiment, when the air inlet pipe orifice 3 of the fan assembly 12 arranged in the inner cavity 4 is used for air intake or when a user deeply inhales air, the spiral fan 5 in the fan assembly 12 rotates to accelerate the air flow under the inertia acting force, and the spiral fan blades 5 are coated with the material for adsorption and sterilization, so that the air can be further sterilized, and the harm to the human body is reduced.
The working principle of the utility model is as follows: air gets into inner chamber 4 from air inlet 3, and gaseous helical fan 5 in the fan group becomes 12 and drives its rotation, has accelerateed the gas flow under helical fan 5 rotation inertia effect, and the gas that acceleratees the flow flows from outlet pipe mouth 7 after filtering through filter screen 6, thereby constantly circulates above-mentioned mode air and constantly flows in fast outflow, and gas resistance is little, and filtration efficiency is high.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
