Air purifying equipment

Abstract

The invention discloses air purifying equipment. The air purifying equipment comprises a neck-worn air purifier and a neck-worn controller, wherein the neck-worn air purifier includes a purifier body, a fan arranged in the purifier body for actively sucking air, and an elastic belt worn at a head part by connecting with the purifier body; the neck-worn controller is worn at a neck part and connected with a head-worn air purifier, is provided with a power supply and a connecting lead, and is used for supplying electricity to the fan and controlling the fan to operate; the fan includes an axial flow guide vane, a front cover plate, a centrifugal movable impeller and a motor, wherein the axial flow guide vane is provided with a center ring and multiple axial flow guide blades around the outer wall of the center ring; the front cover plate takes the shape of a ring with a projection in middle; the centrifugal movable impeller is arranged in space between the front cover plate and the axial flow guide blades; the motor is fixedly mounted on a shell module, and an output shaft thereof is connected with the centrifugal movable impeller; and the centrifugal movable impeller is provided with an annular base and multiple centrifugal blades around one surface of the annular base. The fan is uniform and gentle in exhausting; and the heavier battery weight is transferred to an external controller to relieve long-time wearing discomfort.

Description

technical field [0001] The present invention relates to wearable devices, especially air purification devices. Background technique [0002] In the head-mounted air purification device that actively sucks air for filtration, it is necessary to use a fan to suck air into the air filter layer for air filtration, and the filtered air is supplied to the person's mouth and nose for breathing. [0003] Tang Binhong (Chinese patent, Axial flow fan for mask and its mask, CN205446182U, published on 2016.08.10 and Chinese patent, a kind of active protective mask for children, CN205569545U, published on 2016.09.14) The axial fan designed is relatively common. The fan's wind is enhanced, which can overcome the resistance of the filter layer, and it is convenient for children who have difficulty breathing and the elderly to wear air purifiers. However, since it adopts the form of an axial flow impeller (that is, the axial flow fan moving blade in this invention patent) + axial guide van...

AI Technical Summary

Problems solved by technology

[0007] The above solutions can reduce the discomfort when wearing to a certain extent, but for children or teenagers, long-term wearing (especially in severe haze weather) will cause the rubber belt to be placed on the back of the head and both sides of the head for a long time on the cheeks, causing strangulation marks, which is not beautiful, but also makes them disgusted

Especially in order to save the power for a day, the batteries of these head-mounted air purifiers are also heavy, which makes children and teenagers uncomfortable to wear.

[0008] In short, the existing head-mounted air purification equipment, because the design of the fan is not ideal, and at the same time, in order to maintain the operation of the fan for a long time, the weight of the battery is relatively large. These factors will increase the discomfort when wearing it and affect the user's Experience
