[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6 A hanging air sterilizer for clinical use in hospitals includes a housing 1, an air duct 4 on the inner side of the top of the housing 1, an air inlet 2 on one side of the housing 1, the air inlet 2 being connected to the air duct 4, and a dustproof plate 3 being fixed to the top of the air inlet 2 by bolts.

[0026] A circuit board is installed inside the casing 1. A cross-flow fan 8 is rotatably connected to the inside of the casing 1. The cross-flow fan 8 has a rated air volume of 800-1200m³ / h and a noise level of ≤45dB(A).

[0027] The bottom of the housing 1 has a first opening, and a mounting bracket 11 is inserted into the first opening. A pre-filter 12, an activated carbon fiber filter 13, and a HEPA filter 14 are sequentially inserted through one side of the mounting bracket 11.

[0028] The primary filter 12 can be made of G4 grade non-woven fabric, which can intercept large particles of dust and other pollutants. It can be disassembled, washed with water, and reused. The activated carbon fiber filter 13 can adsorb harmful gases and odors such as formaldehyde and benzene. The HEPA filter 14 is at least H13 grade or higher. The HEPA filter 14 can further filter fine solid pollutants.

[0029] A differential pressure sensor is fixed inside the mounting bracket 11 by bolts. The differential pressure sensor model can be selected as 26P110CLD11A1G. The differential pressure sensor is located between the primary filter screen 12 and the activated carbon fiber filter screen 13. An LED warning light is installed on one side of the outer wall of the housing 1. The LED warning light is electrically connected to the differential pressure sensor. When the filter screen resistance reaches twice the initial value, the LED replacement prompt is triggered.

[0030] The top of the housing 1 has a second opening, and a cover 6 is inserted into the second opening. A protective net 5 is fixed to the bottom of the cover 6 by bolts. The protective net 5 can prevent large pollutants from entering the air duct 4 and blocking the cross-flow fan 8. The two sides of the cover 6 are inserted with locking pins 7, which are engaged with the top of the housing 1.

[0031] The inner wall of the casing 1 is fixed with a plasma module 24 by bolts. The plasma module 24 is mainly composed of a high-voltage electrode group and an ionization chamber. It generates plasma through high-frequency discharge and releases high-energy electrons, positive and negative ions and other active particles. These particles react with the protein shells of bacteria, viruses and other microorganisms, destroying their cell structure and causing them to die. The plasma module 24 has an operating voltage of 5-8kV, an ion concentration of ≥1×10^6 ions / cm³, and an ozone release of <0.05ppm.

[0032] The mounting bracket 11 has two rotating seats 15 welded to its bottom, and the inner wall of the rotating seat 15 is rotatably connected to the same rotating shaft 16. A torsion spring 17 is sleeved on the outer surface of the rotating shaft 16. A mounting seat 18 and a handle 19 are welded to the outer surface of the rotating shaft 16 respectively. One end of the torsion spring 17 is fixedly connected to the mounting bracket 11, and the other end of the torsion spring 17 is fixedly connected to the mounting seat 18. The two ends of the rotating shaft 16 are integrally formed with snap-fit ​​pieces 20.

[0033] The bottom of the housing 1 is fixed with two card holders 21 by bolts, and each card holder 21 has a circular card hole 22 and a plug-in gap 23 on one side, and the circular card hole 22 and the plug-in gap 23 are connected.

[0034] An electrical slot 9 is provided on one side of the casing 1, and a motor 10 and a plasma generator 25 are fixed inside the electrical slot 9 by bolts. The output shaft of the motor 10 is keyed to one end of the cross-flow fan 8. The plasma generator 25 is connected to the plasma module 24. The negative ion generator 25 can enhance the sedimentation of particulate matter. A maintenance cover plate 29 is fixed on one side of the electrical slot 9 by bolts.

[0035] The bottom side of the housing 1 has an air outlet, and the inner wall of the air outlet is welded with multiple guide plates 26. The torsion spring 17, the mounting base 18 and the handle 19 are all located between two rotating seats 15. An electric push rod 27 is rotatably connected in the electrical slot 9, and the electric push rod 27 passes through the housing 1 and is rotatably connected to a dust cover 28. The dust cover 28 can adjust the airflow direction and position. The dust cover 28 can be fixed to a suspension bracket 30 on one side of the housing 1 by bolts. The suspension bracket 30 has an L-shaped structure.

[0036] The circuit board is electrically connected to the cross-flow fan 8, differential pressure sensor, LED warning light, plasma module 24, motor 10, plasma generator 25 and electric push rod 27.

[0037] The working principle of this embodiment is as follows: When in use, the air sterilizer is first connected to the power supply, and then the motor 10 drives the cross-flow fan 8 to rotate. During operation, the cross-flow fan 8 draws in external air through the air inlet 2 and the air duct 4, and passes it through the pre-filter 12, activated carbon fiber filter 13, HEPA filter 14 and plasma module 24 in sequence to filter and disinfect harmful substances in the air. The filtered air is discharged along the guide plate 26 on the air outlet. The electric push rod 27 can control the dust cover 28 to open, thereby adjusting the airflow direction.

[0038] When the air purifier needs maintenance, the filter needs to be replaced regularly. The operator only needs to turn the handle 19 90 degrees, which will cause the rotating shaft 16 to deflect. The locking pieces 20 at both ends of the rotating shaft 16 will deflect along the circular locking holes 22, changing from horizontal to vertical, and thus disengaging from the mounting bracket 21 along the insertion gap 23. The mounting bracket 11 can then be removed. Then, the pre-filter 12, activated carbon fiber filter 13, and HEPA filter 14 on the mounting bracket 11 can be replaced and cleaned. After replacement and cleaning, turn the handle 19 again, so that the locking pieces 20 change from horizontal to vertical and are inserted into the circular locking holes 22 along the insertion gap 23. At this time, release the handle 19. Under the action of the torsion spring 17, the rotating shaft 16 and the locking pieces 20 will rotate, thus locking them together and completing the installation.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
