Description

Technical Field

[0001] The invention belongs to personal protective equipment, and in particular relates to an air disinfection device for personal protection. Background Art

[0002] Respiratory infectious diseases refer to infectious diseases caused by pathogens invading the human body's nasal cavity, throat, trachea and bronchus. The main pathogens are viruses, bacteria, mycoplasma and chlamydia. For example, influenza virus, measles virus, meningococcus, tuberculosis bacillus, etc., are mainly transmitted through droplets, and can also be transmitted through direct close contact or indirect contact. When the respiratory tract is connected to the outside world, there are more opportunities for invasion by various pathogens, which can easily cause the occurrence of respiratory infectious diseases. Therefore, the most direct preventive measure is to disinfect pathogens in the air and block pathogens from entering the respiratory tract. At present, the personal protective equipment that can be carried with you is mainly masks and protective clothing. These protective equipment only play the role of filtering and blocking pathogens from entering the respiratory tract, and have no effect on disinfecting pathogens. Moreover, most of them are disposable and cannot be reused, and they do not meet the requirements of wearing comfort for the human body. Summary of the invention

[0003] The purpose of the present invention is to solve the defects that personal protective equipment does not have the function of disinfecting pathogens, is not comfortable to wear and cannot be reused, and to provide a protective disinfection device that is easy to wear, can disinfect pathogens and can be reused.

[0004] To this end, the present invention adopts the following technical scheme: a protective disinfection device, characterized in that the protective disinfection device includes a neck ring and a breathing mask, the neck ring and the breathing mask are both provided with a cavity surrounded by a shell, the front end of the neck ring and the bottom end of the breathing mask are connected by a connecting part, and the two connecting parts are provided with a connecting through hole connected to the cavity, and the two connecting through holes are connected to each other; the shape of the inner shell of the breathing mask corresponds to the shape of the human face, and the edge of the breathing mask is provided with a sealing ring that can fit the human face to ensure that the nose and mouth can only exchange air with the breathing mask Breathing exchange; an air inlet is provided on the shell of the neck ring, and a breathing vent corresponding to the nostrils and mouth of the human body is provided on the inner shell of the breathing mask, and a disinfection mechanism is contained in the cavity between the air inlet and the breathing vent; an exhaust through hole is provided on the outer shell of the breathing mask, and a one-way valve is installed in the exhaust through hole. The gas exhaled by the human body can enter the cavity of the breathing mask and be discharged outward through the one-way valve. The outside air must enter from the air inlet of the neck ring and be disinfected by the disinfection mechanism to become non-toxic clean air before reaching the breathing vent of the breathing mask.

[0005] As a supplement and improvement to the above technical solution, the present invention also includes the following technical features.

[0006] The disinfection mechanism is an ultraviolet sterilization lamp.

[0007] A fan is arranged in the cavity between the air inlet and the breathing vent, and air is blown toward one side of the breathing vent by the fan to increase the air circulation speed, thereby ensuring that the airflow quickly reaches the human breathing port and meets the oxygen content demand of the human body.

[0008] The connecting part between the neck ring and the breathing mask is a cylinder, and the neck ring and the breathing mask are connected in a plug-in manner through the cylinder, so that the breathing mask can rotate around the center line of the cylinder, and the breathing mask can better cooperate with the rotation of the human head; the fan is accommodated in the inner cavity of the cylinder of the breathing mask, the air inlet end of the fan is connected to the cavity of the neck ring, and the air outlet end of the fan is connected to the cavity of the breathing mask.

[0009] The breathing mask protrudes forwardly in an inclined manner corresponding to the nose of the human body, and the breathing vent is provided on the inner shell at the bottom of the protruding portion. The bottom of the protruding portion faces the air outlet of the fan, so that the clean air flow blown out by the fan can directly pass through the breathing vent.

[0010] The cavity of the collar contains a filter and purifier mechanism, the air input end of the filter and purifier mechanism is connected to the air inlet, and the air output end is connected to the cavity, and the air input from the air inlet is preliminarily purified by the filter and purifier mechanism.

[0011] The fan and disinfection mechanism are powered by batteries or by an external power source through a power cord; the battery is accommodated in the cavity of the neck ring, or is separately arranged outside the neck ring and connected to the neck ring through a wire.

[0012] The protective disinfection device also includes a controller accommodated in the cavity of the neck ring, and an oxygen content gas sensor is accommodated in the cavity of the breathing mask. The oxygen content gas sensor and the fan are connected to the controller. The controller controls the operation of the fan according to the set oxygen content solubility and the real-time oxygen content solubility sensed by the oxygen content gas sensor, thereby realizing automatic control and better meeting the comfort requirements.

[0013] A soft clamping ring is fixed on the inner side of the neck ring. When worn, the soft clamping ring is supported between the neck ring and the human neck, which plays a good supporting and fixing role for the neck ring, reduces the friction damage of the hard neck ring to the neck, and improves wearing comfort.

[0014] The soft collar is a thin-walled soft body with an air cavity inside. When the air cavity is filled with gas, it bulges for support. When it is deflated, it can increase the inner ring space of the neck ring, making it convenient to put it on the neck. After putting it on the neck, the air cavity is inflated.

[0015] The neck ring includes two half circles, the rear ends of the two half circles are connected by a soft connector, and a half cylinder is arranged at the front end of each half circle. The half cylinders are fixed together to form the cylindrical body. When worn, the front end can be opened to be clamped on the neck, and the front end is fixed together by the elastic restoring force of the soft connector, which is convenient to wear.

[0016] The respirator can also be provided with goggles, which are mounted on the respirator shell through a bendable support frame. The position of the goggles can be adjusted so that the frame of the goggles fits tightly against the human eye socket, forming a barrier between the eyes and the external environment, thereby preventing pathogens from invading the human body through the eyes.

[0017] When in use, first disinfect the inner shell surface of the respirator. When wearing it, put the neck ring around the neck so that the sealing ring on the edge of the respirator fits the face. Turn on the power switch to start the disinfection mechanism and the fan. The outside air enters the filtration and purification mechanism through the air inlet, and enters the cavity after filtration and purification. The disinfection mechanism kills the pathogens in the cavity. The clean air after disinfection is blown into the cavity of the respirator by the fan, and is dissipated to the nasal cavity or oral cavity of the human respiratory port through the breathing vent, completing the respiratory gas exchange, and the exhaled turbid air is discharged to the external environment from the one-way valve in the breathing vent and the exhaust hole.

[0018] The present invention can achieve the following beneficial effects: gas exchange is formed by providing a breathing mask with a cavity that can be sealed and fitted with the human face, and the breathing mask is supported by a neck ring with a cavity, and a disinfection mechanism and a filtering and purification mechanism are provided in the cavity of the neck ring to disinfect and purify the air, thereby achieving wearable personal protection and reusability, and easy to carry.
