[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1-4 , a pressure swing adsorption nitrogen generator, comprising a main body component 1; the main body component 1 comprises a nitrogen generator body 11, whose outer side wall is fixedly connected to a support frame 12; a cooling component 2 is arranged on the nitrogen generator body 11, and the cooling component 2 comprises: an insulation shell 21, fixedly connected to the outer side wall of the nitrogen generator body 11; a mounting plate 22, fixedly connected to the outer side wall of the insulation shell 21; a water tank 23, fixedly connected to the top of the mounting plate 22; a water pump 24, fixedly connected to the top of the mounting plate 22, and the water inlet end is inserted into the water tank 23; a cooling pipe 25, fixedly connected to the water outlet end of the water pump 24, inserted into the insulation shell 21, and the other end is inserted into the water tank 23; a water injection pipe 26, inserted into the water tank 23; a heat dissipation port is opened at the top of the water tank 23, and a dustproof plate 4 is fixedly connected to the inner side wall of the water tank 23; a temperature sensor 5 is fixedly connected to the inner side wall of the insulation shell 21.

[0028] When ready for use, the operator places the nitrogen generator body 11 at a designated position through the support frame 12. When the nitrogen generator body 11 is used for a long time and causes the device to overheat, the operator injects cooling water into the water tank 23 through the water injection pipe 26, and then the operator turns on the water pump 24 on the mounting plate 22. At this time, the water pump 24 pumps the cooling water in the water tank 23 into the cooling pipe 25, so that the cooling water flows through the entire cooling pipe 25. Then, through heat transfer, the cooling pipe 25 absorbs the heat from the inner side of the insulation shell 21 and the surface of the nitrogen generator body 11, thereby cooling the nitrogen generator body 11 and keeping it warm through the insulation shell 21, ensuring the normal use of the device, thereby improving the device Practicality; a heat dissipation port is provided on the top of the water tank 23, and a dustproof plate 4 is fixedly connected to the inner wall of the water tank 23, so that the water tank 23 can cool the circulating cooling water through the top heat dissipation port, and the top dustproof plate 4 prevents external dust and other impurities from entering the cooling water during heat dissipation, thereby improving the stability of the device; a temperature sensor 5 is fixedly connected to the inner wall of the insulation shell 21. When the internal temperature of the insulation shell 21 is too high, the temperature sensor 5 transmits an electrical signal to the distribution box, and then transmits the electrical signal to the controller through the distribution box, and then transmits the electrical signal to the water pump 24 through the controller, so that the water pump 24 is automatically turned on without the need for manual operation by the operator, thereby improving the convenience of the device.

[0029] Embodiment 2

[0030] See also Figure 1-4 , based on the first embodiment, a heat dissipation function is added;

[0031] The nitrogen generator body 11 is provided with a heat dissipation assembly 3, which includes: a mounting shell 31 inserted into the heat-insulating shell 21; a filter screen 32 fixedly connected to the inner wall of the mounting shell 31; a heat dissipation fan 33 arranged inside the mounting shell 31; the heat dissipation assembly 3 is evenly arranged in multiple groups; the inner bottom surface of the water tank 23 is set as an inclined surface.

[0032] When the device is cooling, the operator turns on the cooling fan 33 in the mounting shell 31, so that the cooling fan 33 dissipates heat on the surface of the nitrogen generator body 11. At the same time, the external dust can be filtered out through the filter 32 to prevent dust from entering the insulation shell 21, which makes it inconvenient for the operator to clean. At the same time, the cooling fan 33 can dissipate heat for the cooling pipe 25 to ensure the cooling effect of the cooling pipe 25, thereby improving the practicality of the device; the heat dissipation components 3 are evenly arranged in multiple groups, so that the operator can use multiple groups of heat dissipation components 3 to increase the heat dissipation efficiency of the device and improve the heat dissipation effect of the device; the inner bottom surface of the water tank 23 is set as an inclined surface, so that when the device is not in use, the operator can let the cooling water in the water tank 23 flow completely out of the device through the inclined surface of the inner bottom surface of the water tank 23, so as to prevent the cooling water from deteriorating due to long-term non-use, corroding the device and causing damage to the device, thereby improving the safety of the device.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
