Technical Field

[0001] The utility model belongs to the technical field of breathing tubes, and in particular relates to a filtering breathing tube set. Background Art

[0002] During the replacement and installation process of the breathing tube of conventional respiratory equipment, there is a dangerous situation that contaminants contacted by the operator through the ventilator connection parts directly enter the breathing tube and are inhaled by the wearer. Conventional respiratory equipment basically does not take this problem into consideration, or if it is considered, it uses an additional set of filtering equipment to be installed between the ventilator and the breathing tube, which increases the cost investment, increases the difficulty of installation during use, and also increases the wear weight of the equipment.

[0003] The existing authorized public number is CN 212232212U, which discloses a breathing tube with a self-contained filtering function, including: a breathing tube body, a filtering device and a joint, wherein the filtering device includes a flared pipe fitting and a filter layer filled in the flared pipe fitting, wherein one end of the flared pipe fitting is integrally formed with the breathing tube body, and the other end is integrally formed or assembled with the joint. In the utility model, the filter layer filled in the filtering device is directly filled at the air inlet end of the breathing tube to form a filtering and purification space, and the breathing tube body, the filtering device and the joint are used in an integral or integral assembly without adding additional parts. The breathing tube with a self-contained filtering function provided by the utility model is used as a breathing tube part that needs to be replaced and used in conjunction with a commonly used respirator, and no other parts are required during use to assist in achieving the effect of filtering and purifying the breathing air. However, the above-mentioned breathing tube with a self-contained filtering function has a relatively simple structure, so that both exhalation and inhalation pass through the filtering structure, which easily causes the exhaled air to condense into water droplets and affect the filtering effect. Therefore, it is necessary to provide a filtering type breathing tube set to solve the above problems. Utility Model Content

[0004] The technical content of the utility model is to provide a filtering type breathing tube set.

First, the device is connected to a suitable pipeline. When the user inhales, the one-way air inlet valve is opened, and air enters from the air inlet pipe. When the user exhales, the one-way air outlet valve is opened, and the gas is discharged from the air outlet pipe, thereby separating the paths of exhalation and inhalation. During the inhalation process, impurities and dust particles in the air can be filtered through the filter layer to ensure that the air entering the breathing tube is free of impurities, while also avoiding the secondary inhalation of exhaled saliva during inhalation. During the inhalation process, with the assistance of the activated carbon layer, the odor in the gas can be adsorbed to improve the quality of inhalation.

[0006] As a further solution of the present invention, the diversion assembly includes a connecting tube, which is fixedly connected to one end of the connecting sleeve away from the breathing tube, and the bottom of the connecting sleeve is fixedly connected to an exhaust pipe. During use, air enters the breathing tube from the connecting tube when inhaling, and the gas is discharged from the exhaust pipe when exhaling, thereby realizing the diversion of the exhalation and inhalation paths.

[0007] As a further solution of the utility model, a one-way air intake valve is fixedly connected to the interior of the connecting tube. When inhaling, the one-way air intake valve opens, allowing air to enter the interior of the breathing tube from one end of the connecting tube.

[0008] As a further solution of the utility model, a one-way air outlet valve is fixedly connected to the inside of the air outlet pipe. When exhaling, the one-way air outlet valve opens to ensure that the exhaled air is discharged from the air outlet pipe, thereby realizing the diversion of the exhalation and inhalation paths and avoiding the secondary inhalation of exhaled saliva when inhaling.

[0009] As a further solution of the utility model, a filter capsule is fixedly connected to the interior of the air outlet pipe, and filter cotton is sleeved inside the filter capsule. The filter cotton can filter sputum or mist moisture during exhalation.

[0010] As a further solution of the present invention, one end of the connecting tube away from the connecting sleeve is fixedly connected to a filter cartridge, and the outside of the filter cartridge is fixedly connected to an air intake pipe, and the filter cartridge can filter foreign particles in the air.

[0011] As a further solution of the present invention, two filter layers are fixedly connected inside the filter cartridge, and both filter layers are made of high-density filter mesh materials. The filter layers can filter particulate impurities in the air.

[0012] As a further solution of the utility model, an activated carbon layer is fixedly connected to the interior of the filter cartridge, and the activated carbon layer is located in the middle of the two filter layers. The activated carbon layer can filter odors in the inhaled air and improve the air inhalation quality.

[0013] In summary, the present invention includes at least the following beneficial technical effects:

[0014] First, the utility model records that the device is first connected to a suitable pipeline. When the user inhales, the one-way air inlet valve opens, and air enters from the air inlet pipe. When the user exhales, the one-way air outlet valve opens, and the gas is discharged from the air outlet pipe, thereby separating the exhalation and inhalation paths.

[0015] Second, the utility model records a filtering breathing tube set, which records that during the inhalation process, impurities and dust particles in the air can be filtered through the filter layer to ensure that the air entering the breathing tube is free of impurities. During the inhalation process, with the assistance of the activated carbon layer, the odor in the gas can be adsorbed to improve the quality of inhalation.

[0016] Third, the utility model records a filtering breathing tube set, which records the combined use of an air inlet tube and an air outlet tube, so that during the inhalation process, the secondary inhalation of exhaled saliva can be avoided, thereby improving the quality of use.
