[0001] The utility model relates to the technical field of oxygen enrichment devices, in particular to an engine oxygen enrichment device for vehicles traveling in plateau environments. Background Art

[0002] When a vehicle is driving in a plateau environment, the engine will be affected to a certain extent due to the unique climatic conditions of the plateau, such as high altitude, low air pressure, low temperature and thin air.

[0003] In order to solve the oxygen deficiency problem of the car engine when it can be used normally in the plateau environment, an oxygen concentrator is usually installed on the car, and the rich oxygen produced by the oxygen concentrator is used to increase the power output of the engine, making the vehicle more powerful when driving in the plateau area. However, the oxygen concentrator is installed on the car. Although it is protected by the outer shell, a large amount of dust and impurities will still be inhaled when the air is drawn in, which accelerates the service life of the filter element in the oxygen concentrator. In addition, some of the produced oxygen contains water vapor, which causes damage to the engine when it inhales rich oxygen.

[0004] Therefore, the present invention provides an engine oxygen enrichment device for vehicles traveling in plateau environments to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The utility model provides an engine oxygen enrichment device for vehicles traveling in plateau environments, such as Figure 1-5 As shown, the pipette rack includes an air compressor 2 fixedly installed inside the oxygen concentrator housing 1 and an air guide pipe 5 installed on the front of the oxygen concentrator housing 1. A molecular sieve cartridge is provided at the tail end of the air compressor 2, and a filtering mechanism 3 is provided at the air compressor 2.

[0032] The filtering mechanism 3 includes a fixing base 32 mounted on the front side of the oxygen concentrator housing 1, an air duct 5 mounted on the upper end of the fixing base 32, two sets of empty slots are provided at the air duct 5, an installation box 31 is provided on the upper end of the fixing base 32, and two sets of sealing rings 33 are equidistantly installed at the lower end of the installation box 31. The sealing ring 33 close to the oxygen concentrator housing 1 is detachably connected to a high-efficiency filter element 34, and the sealing ring 33 away from the oxygen concentrator housing 1 is detachably connected to an activated carbon filter element 35.

[0033] Specifically, the fixing seat 32 is a base for supporting the air duct 5, and the fixing seat 32 is fixed to the front of the oxygen concentrator housing 1. The two rough slots opened on the air duct 5 are used to assemble the sealing rings 33. The high-efficiency filter element 34 and the activated carbon filter element 35 on the two sets of sealing rings 33 are used to filter impurities and dry the produced oxygen respectively. After the installation box 31 is pushed from top to bottom to the fixing seat 32, the sealing rings 33 fit into the slots and seal. The sealing ring 33 close to the sealing ring of the oxygen concentrator housing 1 is installed with the activated carbon filter element 35, and the other set of sealing rings 33 is installed with the high-efficiency filter element 34, so that the oxygen is first dehumidified and then filtered. Both the high-efficiency filter element 34 and the activated carbon filter element 35 can be removed separately.

[0034] It should be noted that the oxygen concentrator is a common oxygen production equipment in life, and its working system and oxygen production principle are both existing technologies.

[0035] A guide rail 45 is installed on the upper end of the fixing seat 32, and a slide groove 38 is provided on the back of the installation box 31. The slide groove 38 provided on the installation box 31 is slidably connected to the guide rail 45. A slot 42 is symmetrically provided on the upper end of the fixing seat 32, and a plug-in plate 36 is symmetrically provided on the lower end of the installation box 31. A limiting groove 37 is provided on the end of the two sets of plug-in plates 36 away from the oxygen concentrator housing 1. A quick-release component 4 is provided on the front of the fixing seat 32.

[0036] Furthermore, the guide rail 45 installed on the fixed seat 32 guides the sliding groove 38 opened on the installation box 31 to slide up and down. The slot 42 opened on the fixed seat 32 is used for the installation box 31 to move downward, and is connected by the plug-in plate 36, so that the installation box 31 and the fixed seat 32 can be assembled into one.

[0037] The quick-release assembly 4 includes a limit rod 44 fixedly installed at both ends of the pull rod 41, and a movable groove 43 is symmetrically opened on the front of the fixed seat 32, and the movable groove 43 is communicated with the slot 42. The limit rod 44 is slidably connected to the movable groove 43, and a partition is installed on the inner side of the limit rod 44. The partition is installed with a spring 46. The tail end of the spring 46 is fixedly connected to the front of the fixed seat 32. The front end of the limit rod 44 is chamfered, and the limit rod 44 is adapted to the limit groove 37 opened by the plug plate 36.

[0038] Furthermore, the limit rods 44 at both ends of the pull rod 41 slide and penetrate the two movable grooves 43 opened in the fixing seat 32 respectively, and rely on the cooperation of the spring 46 and the partition to limit the position, so that the limit rod 44 is always located inside the movable groove 43. When the installation box 31 moves downward to make the sealing ring 33 seal the air guide tube 5, the plug-in plate 36 is plugged into the inside of the slot 42, and the plug-in plate 36 will squeeze the limit rod 44 outward. When the limit groove 37 and the limit rod 44 are in the same horizontal position, and the spring 46 cooperates to make the limit rod 44 plugged into the limit groove 37 to form a fixed position, so that even when the car is driving on a bumpy road, the installation box 31 can still be kept in a fixed position.

[0039] During use, the device is installed on the car by supplying water into the water tank, and the air outlet of the air duct 5 is connected to the interface for introducing engine gas with a hose. When driving to a plateau area, the oxygen generator housing 1 is started, and the air compressor 2 inside the oxygen generator housing 1 is used to inhale air from the outside, and the nitrogen atoms in the air are stripped off through the molecular sieve cartridge, so that the oxygen atoms are introduced into the air duct 5 through the trachea and discharged to the outside. The oxygen passes through the activated carbon filter element 35 and the high-efficiency filter element 34 on the installation box 31, and the oxygen is dehumidified and dried and impurities are filtered out respectively. Finally, the oxygen enters the engine to prevent moist oxygen from entering the engine and causing damage to the engine. At the same time, after a period of use, the installation box 31 is disassembled from the fixing seat 32, and the high-efficiency filter element 34 and the activated carbon filter element 35 are replaced or cleaned in turn.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
