Description

TECHNICAL FIELD

[0001] The present application relates to air sterilizers, in particular to a high-pressure high-speed flow type air sterilizer. BACKGROUND

[0002] Air sterilizers are machines that sterilize air through filtration, purification, sterilization, and other principles. In addition to killing bacteria, viruses, molds, spores, and other so-called sterilization, some models can also remove formaldehyde, phenol, and other organic pollutants from indoor air, and can also kill or filter allergens such as pollen. At the same time, it can effectively remove smoke and odor produced by smoking, unpleasant odors in the bathroom, and body odor. The sterilization effect is reliable and can be performed in the presence of people.

[0003] The sterilization means of existing air sterilizers mainly includes ultraviolet sterilization, ozone sterilization, photocatalyst sterilization, and negative ion sterilization. Among them, ultraviolet sterilization mainly achieves the inactivation of bacteria in the air. The closer the ultraviolet lamp tube is to the object being sterilized, the more and faster the bacteria are killed. Within the range of ultraviolet radiation, the bacterial mortality rate can be guaranteed to be close to 100%, so it is widely used in various sterilization fields, such as medical sterilization.

[0004] Existing ultraviolet air sterilizers, such as the invention application with the application publication number CN112283857A, disclose an air flow sterilization mechanism and an air flow sterilization machine. The air flow sterilization machine sterilizes air by setting ultraviolet lamps in the sterilization cavity and passing air into the sterilization cavity. The structure is simple and the sterilization effect is good. However, the existing flow air sterilizer still has the following shortcomings:

[0005] The existing flow air sterilizer is only suitable for sterilizing low-flow air. For high-flow air, due to its high speed and the fact that it moves in groups and bundles, the ultraviolet light cannot fully irradiate the flowing air, resulting in poor instant killing effect and the need for improved sterilization effect. It cannot be used in air compressor gas matching sterilization occasions. SUMMARY

[0006] The purpose of the present application is to overcome the above-mentioned problems, and to provide a high-pressure high-speed flow type air sterilizer that can fully and completely sterilize high-speed flowing air, effectively improve the sterilization rate and sterilization speed, and achieve a sterilization rate of 99%. It is especially suitable for use in air compressor gas matching sterilization occasions.

[0007] The purpose of the present application is achieved by the following technical solutions:

[0008] A high-pressure high-speed flow type air sterilizer, comprising a sterilization shell, a pressure reduction and shunt structure arranged in the sterilization shell, and a ultraviolet generating module.

[0009] The disinfection shell is provided with an air inlet and an air outlet;

[0010] The decompression and shunting structure comprises a first decompression and shunting member and a second shunting member; the first decompression and shunting member is arranged between the second shunting member and the air inlet, and a plurality of first decompression and shunting holes are arranged on the side wall of the first decompression and shunting member; the second shunting member is arranged between the first decompression and shunting member and the ultraviolet generating module, and a plurality of second shunting holes are arranged on the bottom of the second shunting member;

[0011] The space between the ultraviolet generating module and the second shunting member forms a disinfection cavity, and the ultraviolet generating module comprises a mounting seat, an ultraviolet lamp and a glass cover plate; the mounting seat is fixedly arranged in the inner cavity of the disinfection shell, and a plurality of air flow communication holes are arranged on the mounting seat and communicate between the disinfection cavity and the air outlet; the ultraviolet lamp is arranged on the mounting seat and faces the second shunting holes in the bottom of the second shunting member; the glass cover plate separates the ultraviolet lamp from the disinfection cavity; in the working state, the high-speed airflow enters from the air inlet, is decompressed, and then is first shunted from the first decompression and shunting holes into the inner cavity of the second shunting member, and then is second shunted from the second shunting holes into the disinfection cavity, and after being disinfected by ultraviolet irradiation, the airflow enters the air flow communication holes and finally flows out from the air outlet.

[0012] The working principle of the high-pressure high-speed airflow type air disinfection device is as follows:

[0013] When working, the high-speed airflow is introduced from the air inlet of the disinfection shell, and the high-speed airflow first hits the bottom of the first decompression and shunting member, at this time the air pressure of the airflow is reduced, and then the airflow is preliminarily shunted from the first decompression and shunting holes around; the airflow that has been preliminarily shunted enters the inner cavity of the second shunting member, and under the guidance of the inner side wall of the second shunting member, the airflow is further shunted from the second shunting holes in the bottom of the second shunting member to the disinfection cavity; at this time, the airflow is fully dispersed and uniformly flows towards the direction of the ultraviolet lamp, and in this process, the ultraviolet light emitted by the ultraviolet lamp irradiates the air in the disinfection cavity without dead angle, so that the cell chains of the bacteria in the air are broken and die, effectively improving the disinfection rate and disinfection speed, and especially suitable for the disinfection of compressed gas. Then, since the ultraviolet lamp is arranged towards the second shunting holes in the bottom of the second shunting member, the airflow that is second shunted directly hits the ultraviolet lamp, and under the blockage of the glass cover plate, the airflow that has been disinfected enters the air flow communication holes and finally passes through the air outlet of the disinfection shell.

[0014] In one preferred embodiment of the present application, the air inlet and the air outlet of the disinfection shell are each provided with a plug, an air nozzle and a nut; the plug is threadedly connected to the end of the disinfection shell; the air nozzle is fixed in the inner cavity of the plug; and the nut is locked to the outer end of the air nozzle.

[0015] In one preferred scheme of the present application, the bottom of the primary pressure-reducing flow distributor is provided with a partial spherical flow guiding boss, which is directed towards the air inlet. After the high-speed airflow is injected, it directly hits the flow guiding boss, and under the guidance of the flow guiding boss, the airflow is evenly submerged and dispersed in all directions, which not only improves the uniformity of the airflow dispersion, but also effectively ensures the smoothness of the airflow and improves the efficiency of the flow.

[0016] In one preferred scheme of the present application, a plurality of primary pressure-reducing flow holes are uniformly arranged on the side wall of the primary pressure-reducing flow distributor along the circumferential direction.

[0017] In one preferred scheme of the present application, the inner wall of the secondary flow distributor is in a tapered structure that gradually narrows towards the bottom surface, and the upper end of the inner wall is opposite to the primary pressure-reducing flow hole of the primary pressure-reducing flow distributor. In this way, the airflow from all the primary pressure-reducing flow holes is uniformly guided downwards to the secondary flow hole, so that the secondary flow hole further distributes the airflow on the basis of the primary pressure-reducing flow hole. The front and rear structures are mutually corresponding and related, and the levels are progressive, which not only has a good effect on the dispersion of the airflow, but also has a very compact and ingenious structure.

[0018] In one preferred scheme of the present application, the outer wall surface of the secondary flow distributor is provided with an electroplated light-reflecting layer, which is used to reflect ultraviolet light to increase the sterilization effect.

[0019] In one preferred scheme of the present application, the mounting seat is connected to the inner wall of the sterilization shell through a threaded structure.

[0020] In one preferred scheme of the present application, a plurality of secondary flow holes are uniformly arranged on the outer side wall of the mounting seat along the circumferential direction, and the ultraviolet lamp is located in the middle of the plurality of secondary flow holes. In this way, the air that has been distributed by the secondary flow flows towards the ultraviolet lamp along the middle position, is blocked by the glass cover plate, and then is dispersed to the plurality of secondary flow holes.

[0021] In one preferred scheme of the present application, the mounting seat is provided with a first mounting groove at one end close to the sterilization cavity, the ultraviolet lamp and the glass cover plate are arranged in the first mounting groove, a clamping spring is arranged at the opening of the first mounting groove to press and fix the glass cover plate, and a sealing gasket is arranged between the glass cover plate and the mounting seat.

[0022] Further, the mounting seat is provided with a second mounting groove at one end away from the sterilization cavity.

[0023] The ultraviolet generating module further comprises a driving power supply, which is arranged in the second mounting groove and is electrically connected to the ultraviolet lamp.

[0024] Further, the sterilization shell is provided with a power supply inlet, which is used to connect the power supply line to the driving power supply.

[0025] Compared with the prior art, the present application has the following advantages:

[0026] 1. The high-pressure high-speed flow type air sterilizer has one-stage pressure reduction and flow division member and two-stage flow division member, which can reduce the pressure of the high-speed airflow, divide the airflow in one stage and two stages, fully disperse the airflow, and irradiate the airflow without dead angle, so that the cell chains of the bacteria in the air are broken and die, the sterilization rate and sterilization speed are effectively improved, the sterilization rate reaches 99%, and the sterilizer is especially suitable for the sterilization of compressed gas.

[0027] 2. The airflow from the two-stage flow division member directly hits the ultraviolet lamp, on the one hand, the air can be in close contact with the ultraviolet light, and the sterilization intensity of each air is the same, so that the sterilization effect is further improved; on the other hand, the flow direction of the airflow is opposite to the emission direction of the ultraviolet light, that is, the ultraviolet light is in contact with the airflow more quickly, so that the sterilization efficiency is further improved.

[0028] 3. The ultraviolet light irradiates the bacteria to break the cell chains and die, and the sterilization is physical, without adding other chemical sterilization factors, so that the sterilization is safer and more reliable. BRIEF DESCRIPTION OF DRAWINGS
