Description

This application is based upon and claims priority to Chinese Patent Application No. 202210246625.0, filed on Mar. 14, 2022, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present invention relates to the field of life-saving articles and in particular to a vehicle-carried first aid kit. BACKGROUND Vehicle-carried first aid kit is a bag provided with medical first aid equipment and medications on a vehicle, which can be used to carry out self-rescue upon occurrence of deaths or injuries caused by traffic accidents and therefore can be regarded as one of major approaches to effectively reduce the death toll of traffic accidents. But, the vehicle-carried first aid kits on the current market are only applicable to the problems of minor abrasions or bleeding arising from traffic accidents and cannot cope with a severe circumstance of a vehicle running across water, bringing limitations to use of the vehicle-carried first aid kit. Therefore, it is urgent to need a vehicle-carried first aid kit which can not only handle the common problems of abrasions or bleeding but also carry out emergency oxygen inhalation for a drowning person in time during an accident of a vehicle running across water. SUMMARY In order to address the above technical problems, the present invention provides a vehicle-carried first aid kit which is provided with a portable respirator and oxygen inhalation goggles to carry out emergency respiration treatment for a drowning person in different conditions. The present invention adopts the following technical solution. A vehicle-carried first aid kit is provided, which comprises a first aid kit body. The first aid kit body is internally provided with a portable respirator, oxygen inhalation goggles, a floating rope, a first aid bracelet, a military shovel, cut-resistant gloves, a multifunctional tool bag and a medical supply bag. The portable respirator comprises a main valve body and a gas cylinder. A pressure relief diaphragm is mounted inside the main valve body. An outer side of the pressure relief diaphragm is in communication with the atmospheric environment and an inner side of the pressure relief diaphragm forms a low-pressure compartment with an inner wall of the main valve body. The low-pressure compartment is in communication with a gas outlet of a gas outlet end of the gas cylinder through an inlet gas channel. A pressure relief valve is disposed inside the main valve body. A pressure relief channel in communication with the inlet gas channel and the low-pressure compartment is disposed in a valve body of the pressure relief valve. A pressure relief opening is disposed on the valve body of the pressure relief valve. The pressure relief diaphragm is linked with the pressure relief valve through a pressing mechanism. The main valve body is provided with an inflation opening in communication with the inlet gas channel and a mouthpiece interface in communication with the low-pressure compartment. An exhaust opening in communication with the low-pressure compartment is disposed at the bottom of the main valve body, and the exhaust opening is provided with a one-way exhaust diaphragm. The oxygen inhalation goggles comprise a goggle frame fitted with lenses and a flexible skirt edge disposed around the goggle frame to form a respiratory chamber. An inlet gas tube is inserted into the flexible skirt edge. One end of the inlet gas tube communicates with the respiratory chamber and extends to a nose part, where the end is provided with nose plugs for ease of inhalation; and the other end of the inlet gas tube is connected with a portable oxygen cylinder. The goggle frame is provided with a binding strap fixed to a head part, and the binding strap is provided with an elastic strap for detachably mounting the portable oxygen cylinder to the binding strap. With the above structure, the present invention has the following advantages: the floating rope, the first aid bracelet, the military shovel, the cut-resistant gloves, a multifunctional tool bag and a medical supply bag can satisfy regular on-water emergency requirements and the portable respirator and the oxygen inhalation goggles can be used to carry out emergency respiration rescue for a drowning person. Especially in an emergency of hypoxia, the portable respirator and the oxygen inhalation goggles can be quickly applied due to their portability and light weight. When inhalation is performed using the portable respirator, the pressure relief diaphragm in the low-pressure compartment deforms downwardly to push the pressing mechanism to press down, thus pushing a piston of the pressure relief valve to run downwardly. In this way, the pressure relief channel is communicated with the inlet gas channel to enable gas in the inlet gas channel to enter the low-pressure compartment for inhalation by a user. When exhalation is performed, the pressure relief diaphragm deforms upwardly to loosen the pressing mech
