Description

Technical Field

[0001] This utility model belongs to the field of ultraviolet lamp timing technology, specifically relating to a timing device for the use of ultraviolet lamps. Background Technology

[0002] Ultraviolet (UV) lamp irradiation disinfection is widely used, especially in medical institutions, where UV lamps are required for disinfection of air and object surfaces in examination rooms, treatment rooms, pharmacies, and wards. A commonly used 30W straight-tube UV lamp in clinical practice should have an intensity of ≥70μW / cm². 2 Only in this way can disinfection requirements be met. According to the standards of the Health Supervision Association, ultraviolet lamps should be replaced in batches after 1000 hours of use in clinical settings to ensure disinfection effectiveness. Therefore, most medical institutions keep statistics on the cumulative usage time of ultraviolet lamps and replace them promptly to ensure the intensity of irradiation.

[0003] The existing ultraviolet lamps do not have a corresponding timing device for coordinated use. The usage time of the ultraviolet lamps is manually counted or detected by using an ultraviolet lamp intensity detector or an ultraviolet intensity test card. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a timing device for the use of ultraviolet lamps, so as to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A timing device for ultraviolet lamps includes an ultraviolet lamp, with connectors at both ends of the ultraviolet lamp. A brightness sensor is mounted on each connector. When the ultraviolet lamp is on, the brightness sensor receives a signal. The signal output of the brightness sensor is connected to a power-on timer. The output of the power-on timer is connected to a photoelectric alarm. A blocking assembly for blocking the ultraviolet lamp is mounted on the two connectors. A control assembly is mounted on the blocking assembly to control the blocking assembly's operation of the ultraviolet lamp.

[0007] Further specifying, the shielding assembly includes a take-up drum, in which a light-blocking cloth is wound up, the take-up drum has an outlet for the light-blocking cloth, the light-blocking cloth is wound around a rotating drum, and coil springs are assembled and connected to both ends of the rotating drum.

[0009] Furthermore, a positioning rod is connected between one end of the light-blocking cloth and the connecting rope, and the positioning rod is fixedly connected to the edge of the light-blocking cloth.

[0010] Further specifying, the connector has an annular groove, the annular groove of the connector is on the outer ring of the ultraviolet lamp tube, and the end of the positioning rod slides in the annular groove.

[0011] Further specifying, the driving mechanism includes a rotating rod, which is fixedly connected to the lower end of the connecting rope, and the rotating rod is rotatably connected to the two connecting members. A motor is assembled and connected to one end of the rotating rod.

[0030] like Figure 1-5 As shown, a timing device for ultraviolet lamp tube usage includes an ultraviolet lamp tube 1. Connectors 2 are provided at both ends of the ultraviolet lamp tube 1. A brightness sensor 3 is assembled and connected to the connector 2. When the ultraviolet lamp tube 1 is in the on state, the brightness sensor 3 receives a signal. The signal output terminal of the brightness sensor 3 is connected to a power-on timer 4. The output terminal of the power-on timer 4 is connected to a photoelectric alarm 5. A blocking component 6 for blocking the ultraviolet lamp tube 1 is assembled and connected to the two connectors 2. A control component 7 is assembled and connected to the blocking component 6. The control component 7 is used to control the blocking component 6 to block and open the ultraviolet lamp tube 1.

[0031] In this embodiment, the ultraviolet lamp 1 emits ultraviolet light to sterilize and disinfect the room. The connector 2 is used to install the ultraviolet lamp 1. Two brightness sensors 3 are used to detect whether the ultraviolet lamp 1 is turned on. When the ultraviolet lamp 1 is turned on, the brightness sensors 3 receive a signal, which is transmitted to the power-on timer 4. The power-on timer 4 calculates the power-on time. When the cumulative power-on time of the ultraviolet lamp 1 reaches 1000 hours, the photoelectric alarm 5 receives a signal and emits a flashing signal, so that staff can promptly detect that the ultraviolet lamp 1 has reached the designated time of use, facilitating... When replacing the ultraviolet lamp 1, the brightness sensor 3 can detect the change in brightness when the shielding component 6 blocks the ultraviolet lamp 1, thereby sensing the usage status of the ultraviolet lamp 1. By setting the shielding component 6, the shielding component 6 can block the ultraviolet lamp 1 when it is not in use, reducing the dust falling on the outside of the ultraviolet lamp 1. Before using the ultraviolet lamp, the staff can open the shielding component 6 to put the ultraviolet lamp in a blocked state, reducing the harm of the ultraviolet lamp to the staff. The connector 2 on one side is fixedly connected to the support base, so that the ultraviolet lamp 1 is at a certain height.

[0032] Reference Figure 2 and Figure 4 The shielding assembly 6 includes a take-up drum 61, in which a light-shielding cloth 62 is wound up. The take-up drum 61 has an outlet for the light-shielding cloth 62. The light-shielding cloth 62 is wound around a rotating drum 63, and coil springs are fitted to both ends of the rotating drum 63. In this embodiment, the light-shielding cloth 62 is located inside the take-up drum 61, and the coil springs are used to keep the rotating drum 63 wound around the light-shielding cloth 62 when the lower end of the light-shielding cloth 62 is not subjected to external force.

[0033] Reference Figure 2-3 The control component 7 includes a connecting rope 71, the upper end of which is connected to the lower end of the light-shielding cloth 62. The lower end of the connecting rope 71 is connected to a drive mechanism 72 that causes the light-shielding cloth 62 to cover the ultraviolet lamp tube 1. In this embodiment, the control component 7 is used to control the light-shielding cloth 62 to move downward. The connecting rope 71 is connected to the lower end of the light-shielding cloth 62. The drive mechanism 72 can be a rope winder to wind up the connecting rope 71, or it can be a lifting mechanism to drive the lower end of the connecting rope 71 to move downward.

[0034] Reference Figure 1-2 A positioning rod 621 is connected between one end of the light-blocking cloth 62 and the connecting rope 71, and the positioning rod 621 is fixedly connected to the edge of the light-blocking cloth 62. In this embodiment, the positioning rod 621 is provided to keep the edge of the light-blocking cloth 62 flat, thereby preventing gaps from being left between the two light-blocking cloths 62 after the light-blocking cloth 62 is pulled down.

[0035] Reference Figure 2 The connector 2 has an annular groove on its outer ring around the ultraviolet lamp tube 1, and the end of the positioning rod 621 slides within the annular groove. In this embodiment, the annular groove is used to limit the movement path of the positioning rod 621, preventing it from contacting the ultraviolet lamp tube 1 during downward movement and causing damage to the ultraviolet lamp tube 1.

[0036] Reference Figure 2 The drive mechanism 72 includes a rotating rod 721, which is fixedly connected to the lower end of the connecting rope 71. The rotating rod 721 is rotatably connected to two connecting pieces 2, and a motor 722 is mounted on one end of the rotating rod 721. In this embodiment, the drive mechanism 72 is connected to a remote control device, thereby enabling remote control of the drive mechanism 72. When the rotating rod 721 rotates, it winds up the connecting rope 71, causing the lower end of the light-shielding cloth 62 to move downwards and cover the ultraviolet lamp tube 1. The motor 722 controls the rotation of the rotating rod 721.

[0037] The shielding component 6 comprises two sets, which are arranged symmetrically. By setting two sets of shielding components 6, the ultraviolet lamp tube is shielded from all directions, effectively reducing the adhesion of dust. When there is only one set of shielding components 6, it can block the light source on one side, reducing the damage of ultraviolet rays to medical staff when they leave after turning on the ultraviolet lamp tube.

[0038] Reference Figure 1 The two take-up drums 61 are arranged adjacent to each other. In this embodiment, the two take-up drums 61 are arranged adjacent to each other, which reduces the gap between the two take-up drums 61, thereby effectively reducing light output.

[0039] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
