Description

Technical Field

[0001] This utility model relates to the field of ultraviolet germicidal lamp technology, specifically a retractable ultraviolet germicidal lamp for surgical clean rooms. Background Technology

[0002] Ultraviolet germicidal lamps in operating cleanrooms are devices used to disinfect the operating room environment. They utilize the strong bactericidal effect of ultraviolet light to effectively kill bacteria, viruses, molds, and other microorganisms in the air, thereby reducing the risk of surgical infection and ensuring surgical safety.

[0003] Ultraviolet germicidal lamps are usually installed on the ceiling or walls of operating rooms. They are turned on at regular intervals to circulate and disinfect the indoor air. The working principle is that ultraviolet rays destroy the DNA structure of microorganisms, causing them to lose their ability to reproduce. During use, care should be taken to avoid direct exposure of the human body to ultraviolet rays to prevent damage to the skin and eyes. At the same time, the surface of the lamp tube should be cleaned regularly to ensure effective emission of ultraviolet rays and maintain good disinfection effect.

[0004] Ultraviolet germicidal lamps installed on the ceiling of surgical clean rooms are generally installed and fixed by hanging in actual use. During the sterilization and disinfection of the operating room, there are blind spots at the top of the ultraviolet germicidal lamp due to the angle of ultraviolet irradiation. Therefore, to address the above problem, a retractable ultraviolet germicidal lamp for surgical clean rooms is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a retractable ultraviolet germicidal lamp for surgical clean rooms, in order to solve the problem that ultraviolet germicidal lamps installed on the roof of surgical clean rooms are generally installed and fixed by hanging in actual use. During the sterilization and disinfection of the inside of the operating room, there are dead corners at the top of the ultraviolet germicidal lamp due to the angle of ultraviolet germicidal lamp irradiation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A retractable ultraviolet germicidal lamp for a surgical cleanroom includes an ultraviolet germicidal lamp body for disinfection of the surgical cleanroom. Both ends of the ultraviolet germicidal lamp body are connected to guide units via a drive unit and a driven unit.

A first tooth is fixedly connected at equal intervals in a ring at one end of the connecting shaft, and an adapter groove is provided at equal intervals in a ring at the other end of the connecting shaft. The striking unit includes a fixing frame with a protrusion fixedly connected to one side of its upper end. The driven unit includes a rotating shaft with a second tooth distributed at equal intervals in a ring on its outer side.

[0008] As a further optimization of this utility model, the guide plate engages with the first tooth that is fixedly connected to the outside of the connecting shaft via a tooth groove, the first slide groove is adapted to the positioning slide plate, and the second slide groove is adapted to the square plate disposed inside the drive component.

[0009] As a further optimization of this utility model, the positioning slide and the connecting shaft are rotatably connected, and the vertical projection of the positioning slide is a cross shape.

[0010] As a further optimization of this utility model, the end of the square plate away from the stepper motor is rotatably connected to the rotating shaft, and the center points of the square plate, the rotating shaft, and the connecting shaft are set on the same horizontal plane.

[0011] As a further optimization of this utility model, the connecting shaft is disposed inside the second slide groove, and the connecting shaft is in close contact with the fixing frame.

[0012] As a further optimization of this utility model, the lateral projection of the adapter groove is a triangle, and the lateral projection of the protrusion is a semicircle.

[0013] As a further optimization of this utility model, the second tooth meshes with the toothed plate, the rotating shaft is fixedly connected to the body of the ultraviolet germicidal lamp, and the toothed plate is L-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, through the setting of a guide unit, a toothed plate, a drive unit, and a driven unit, the ultraviolet germicidal lamp can be raised and lowered during the sterilization and disinfection of the surgical clean room by moving up and down. During the raising and lowering process, the toothed plate controls the rotation of the ultraviolet germicidal lamp, thereby changing the irradiation angle of the ultraviolet germicidal lamp body and effectively increasing the irradiation and sterilization range of the ultraviolet germicidal lamp. At the same time, during the rotation of the ultraviolet germicidal lamp body, the connecting shaft is vibrated by the fixing frame, which effectively removes some of the dust attached to the surface of the ultraviolet germicidal lamp body, ensuring the maximum emission efficiency of ultraviolet rays.

[0033] Please see Figures 1-8 This utility model provides a technical solution:

[0034] A retractable ultraviolet germicidal lamp for a surgical cleanroom includes an ultraviolet germicidal lamp body 1 for disinfection of the surgical cleanroom. Both ends of the ultraviolet germicidal lamp body 1 are connected to guide units 2 via a drive unit 4 and a driven unit 5. A toothed plate 3 adapted to the driven unit 5 is installed on one side of the lower end of the guide unit 2. The guide unit 2 includes a guide plate 21, which has a toothed groove 22, a first sliding groove 23, and a second sliding groove 24 inside. The drive unit 4 includes a positioning slide plate 41, with a drive component 42 installed inside the positioning slide plate 41 and a knocking mechanism installed on the side of the positioning slide plate 41. The striking unit 43 and the driving component 42 include a square plate 421. A stepper motor 422 is fixedly connected to the inner side of one end of the square plate 421. A connecting shaft 424 is fixedly connected to the top of the main shaft of the stepper motor 422. A first tooth 423 is fixedly connected to one end of the outer side of the connecting shaft 424 in an annular shape at equal intervals. An adapter groove 425 is opened in an annular shape at equal intervals at the other end of the connecting shaft 424. The striking unit 43 includes a fixing frame 431. A protrusion 432 is fixedly connected to one side of the upper end of the fixing frame 431. The driven unit 5 includes a rotating shaft 51. A second tooth 52 is distributed in an annular shape at equal intervals on the outer side of the rotating shaft 51.

[0035] As a further implementation of this solution, the guide plate 21 engages with the first tooth 423 fixedly connected to the outside of the connecting shaft 424 through the tooth groove 22, the first slide groove 23 is adapted to the positioning slide plate 41, and the second slide groove 24 is adapted to the square plate 421 provided inside the drive component 42. Through the above settings, the positioning slide plate 41 and the square plate 421 can be stably limited to ensure their stability during the up and down movement.

[0036] As a further implementation of this solution, the positioning slide plate 41 and the connecting shaft 424 are rotatably connected, and the vertical projection of the positioning slide plate 41 is a cross shape. Through the above settings, the rotational stability of the connecting shaft 424 can be further improved.

[0037] As a further implementation of this solution, the end of the square plate 421 away from the stepper motor 422 is rotatably connected to the rotating shaft 51. The center points of the square plate 421, the rotating shaft 51, and the connecting shaft 424 are set on the same horizontal plane. Through the above arrangement, the overall stability of the equipment during operation can be further improved.

[0038] As a further implementation of this solution, the connecting shaft 424 is disposed inside the second slide groove 24, and the connecting shaft 424 is in close contact with the fixing frame 431. With the above arrangement, the fixing frame 431 can be stably struck while the connecting shaft 424 is positioned.

[0039] As a further implementation of this solution, the lateral projection of the adapter slot 425 is a triangle, and the lateral projection of the protrusion 432 is a semicircle. Through the above settings, the problem of jamming between the protrusion 432 and the adapter slot 425 can be prevented.

[0040] As a further implementation of this solution, the second tooth 52 meshes with the tooth plate 3, and the rotating shaft 51 is fixedly connected to the ultraviolet germicidal lamp body 1. The tooth plate 3 is L-shaped. Through the above arrangement, the ultraviolet germicidal lamp body 1 can rotate during the up and down movement, thereby improving the irradiation and sterilization range of the ultraviolet germicidal lamp.

[0041] Workflow: During operation, the ultraviolet germicidal lamp and stepper motor 422 are powered by an external power source. When disinfection is required, the ultraviolet germicidal lamp is powered on. After the ultraviolet germicidal lamp has been running for a period of time, the stepper motor 422 will drive the connecting shaft 424 to rotate. During the rotation of the connecting shaft 424, the first tooth 423 and the tooth groove 22 cooperate with each other to move the ultraviolet germicidal lamp body 1 upward. During the upward movement of the ultraviolet germicidal lamp body 1, the tooth plate 3, in cooperation with the second tooth 52, causes the ultraviolet germicidal lamp body 1 to rotate, thereby changing the irradiation angle of the ultraviolet germicidal lamp body 1 and effectively improving the irradiation and sterilization range of the ultraviolet germicidal lamp.

[0042] During this process, when the connecting shaft 424 rotates, the protrusion 432 will jump in the annularly distributed adapter groove 425 inside it, which will cause the fixing bracket 431 to tap the top of the connecting shaft 424 slightly. The vibration generated during the tapping process can remove some of the dust attached to the surface of the ultraviolet germicidal lamp body 1, which can ensure the maximum emission efficiency of ultraviolet rays.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
