Automatic control device for UV lamp of acarus killing instrument and anti-interference method

Abstract

The invention discloses an automatic control device for a UV lamp of an acarus killing instrument, and belongs to the technical field of acarus killing devices.The automatic control device comprises the acarus killing instrument and a UV lampautomatic control unit; the acarus killing instrument comprises a dust suction opening and a dust suction chamber in butt joint with the dust suction opening; a filtering piece is arranged in the dust suction chamber; an air suction motor is arranged on the rear side of the dust suction chamber; the UV lamp is arranged at the bottom of the acarus killing instrument; and the UV lamp automatic control unit comprises an infrared emitting part, an infrared receiving part and a control unit, wherein the control unit is electrically connected with the UV lamp. The distance between the acarus killing instrument and the bed surface is determined by adopting the infrared transmitting part to transmit the infrared signal and adopting the infrared receiving part to collect the intensity of the reflected signal; when the intensity of the reflected signal is detected to be larger than the preset value, the ultraviolet lamp is turned on; when the acarus killing instrument is lifted by a certain height or inclined by a certain angle, the ultraviolet lamp is turned off so as to prevent ultraviolet light from leaking; and meanwhile, infrared filters are additionally arranged on the infrared transmitting part and the infrared receiving part, so that the anti-interference capability of infrared signals is improved.

Description

technical field [0001] The invention belongs to the technical field of mite removal devices, and in particular relates to an automatic control device and an anti-interference method for a UV lamp of a mite removal device. Background technique [0002] Mites, a tiny pest that is not easily seen by the naked eye, their dead bodies, secretions, and excretions are a strong allergen. Research shows that the total incidence of allergies in China accounts for nearly one-third of the total population in China. Among patients with allergic diseases, up to 70% of the allergens are mites, and the proportion of children is even higher. Allergic diseases caused by mites mainly include allergic rhinitis, allergic conjunctivitis, allergic asthma, and allergic dermatitis, which not only adversely affect the daily life and work of patients, but may even be life-threatening in severe cases. [0003] The mite remover is a common household mite remover appliance, which mainly relies on the lam...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is: in order to solve the harm caused by the leakage of ultraviolet light at the bottom of the existing mite removal instrument, although the micro switch is used as the trigger signal of the ultraviolet lamp in the existing market, the softness of the bed surface will cause damage to the human body. An automatic control device and anti-interference method for UV lamps of the mite remover are proposed because the mite remover cannot be started and the use of the mite remover is affected.
