[0002] Hospital consulting rooms, treatment rooms, infectious disease wards and other spaces often need to be disinfected to kill pathogenic microorganisms remaining on indoor items to prevent the spread of germs and the occurrence of hospital-acquired infections. Ultraviolet light disinfection is currently a commonly used indoor disinfection method in hospitals. When the room is vacated and the doors and windows are closed, the ultraviolet lamp hanging on the roof or placed indoors is turned on to irradiate the room. Ultraviolet rays can destroy the DNA structure of microorganisms and thus exert a disinfection effect. However, the irradiation intensity of the ultraviolet lamp will decrease with the extension of the use time, which will affect the disinfection effect. Therefore, the ultraviolet disinfection lamp has a set service life when it leaves the factory. When the lamp reaches its service life, it should be replaced in time.

[0003] At present, the statistics of the use time of ultraviolet disinfection lamps are generally recorded through paper registration books, and the start and end time of the ultraviolet lamps are manually recorded, so as to calculate the total use time of the lamps, and replace them when the lamps reach the end of their service life. However, manual registration of the use time of ultraviolet lamps is time-consuming and laborious, and it is easy to miss or make mistakes, which affects the estimation of the lamp use time. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an ultraviolet disinfection lamp with a timing function, which solves the problem of time-consuming and laborious manual counting of the use time of the ultraviolet disinfection lamp.

[0031] 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.

[0032] See also Figure 1-Figure 6 The utility model discloses an ultraviolet disinfection lamp with a timing function, comprising:

[0033] A lamp holder 1, wherein an ultraviolet lamp tube 2 is installed inside the lamp holder 1, and a notch 11 is provided on one side of the lamp holder 1 for installation, removal and lighting of the ultraviolet lamp tube 2;

[0034] The timer 3 is slidably mounted inside one end of the lamp holder 1, and the timer 3 and the power supply section of the lamp holder 1 are energized through the contact electrode 5;

[0035] The limiting sheath 4 is sleeved on the outside of one end of the lamp holder 1 where the timer 3 is installed, and after the limiting sheath 4 is installed, it covers the ultraviolet lamp 2 to limit the removal of the ultraviolet lamp 2;

[0036] A limiting structure 12 is provided inside one end of the lamp holder 1 to limit the position of the timer 3 to keep the contact electrodes 5 in contact or separation, and a pushing structure 41 is provided inside the limiting sheath 4 to push out the timer 3 and separate the contact electrodes 5 when pulled out.

[0037] In this embodiment, the contact electrode 5 is divided into two groups and respectively installed at the opposite end of the timer 3 and the lamp holder 1. The contact electrode 5 includes an inner electrode sheet and an outer electrode sheet that do not contact each other. The inner electrode sheet and the outer electrode sheet on the lamp holder 1 are connected by an insulating sheet 13. The inner electrode sheet and the outer electrode sheet are divided into inner and outer circles, and can also be set as two unconnected electrode sheets in other forms. When the contact electrode 5 is in contact, the timer 3 is connected in parallel with the ultraviolet lamp 2, and the timer 3 is powered on and works synchronously when the ultraviolet lamp 2 is powered on.

[0038] In this embodiment, the timer 3 includes a timer body 31, and a reset switch 32 is installed at the other end of the timer body 31. By pressing the reset switch 32, the time measured by the timer body 31 is reset to zero. A memory is provided in the timer body 31. Each time it is turned on, the timer continues to measure the time measured last time, and is reset only after the reset switch 32 is pressed.

[0039] One end of the lamp holder 1 for mounting the timer 3 is an elastic metal tube, the limiting structure 12 is a concave ring arranged in the middle of the elastic metal tube, and a through groove 14 is provided in the elastic metal tube at a position corresponding to the pushing structure 41, and a convex ring 33 is provided in the middle of the timer body 31. When the convex ring 33 of the timer 3 is located on both sides of the concave ring, the two groups of contact electrodes 5 are respectively in contact and separation states. In the separation state, the convex ring 33 is pushed over the concave ring by pressing the reset switch 32.

[0040] In this embodiment, the pushing structure 41 is a bent spring piece with one end fixed to the inner surface of the limiting sheath 4 and the other end tilted. When the pushing structure 41 is pulled outward, the tilted section of the bent spring piece pushes the convex ring 33. When the pushing structure 41 is pushed inward, the tilted section of the bent spring piece is pressed by the convex ring 33 and moves closer to the inner surface of the limiting sheath 4. In order to facilitate the removal of the pushed out timer 3 from the limiting sheath 4, the convex ring 33 on the side of the timer 3 is intermittently arranged. The timer 3 can be taken out by rotating the timer 3 so that the interrupted part of the convex ring 33 is aligned with the bent spring piece.

[0041] In this embodiment, an indicator light 34 is installed on one side of the timer body 31. The indicator light 34 is divided into a working indication state and a warning state according to the color of the light. When the indicator light 34 is in the warning state, the ultraviolet lamp 2 needs to be replaced. The green light is on in the working indication state and the red light is on in the warning state. A through hole 15 is provided in the elastic metal tube part of the lamp holder 1 corresponding to the position of the indicator light 34, and a lens 42 is provided on the limiting sheath 4 corresponding to the through hole 15. In order to accurately position the angle of the timer body 31 so that the indicator light 34 is aligned with the through hole 15 and the lens 42, a positioning edge 35 is provided on one side of the timer body 31, and a positioning groove 16 corresponding to the positioning edge 35 is provided at one end of the elastic metal tube of the lamp holder 1.

[0042] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0043] When installing the ultraviolet lamp 2, first remove the limiting sheath 4, use the tilted pushing structure 41 to push the convex ring 33, and then push the timer 3 to break through the limit of the limiting structure 12 and take it out together, then turn the limiting sheath 4 upside down, turn the timer 3 so that the discontinuous part of the convex ring 33 on it is aligned with the limiting structure 12, and then the timer 3 can be turned out. At this time, install the ultraviolet lamp 2, put the timer 3 into the lamp holder 1, and then power on the lamp holder 1, press the reset switch 32 to push the timer 3 so that the convex ring 33 breaks through the limiting structure 12, until the contact electrode 5 on the timer body 31 is aligned with the contact electrode on the lamp holder 1. The electrode 5 is in contact and energized. At this time, since the reset switch 32 is pressed, the count of the timer 3 is reset, and then the lamp holder 1 is powered off, and the ultraviolet lamp 2 is installed. Then, the lens 42 is kept aligned with the angle of the indicator light 34 and the limiting sheath 4 is put on until the pushing structure 41 breaks through the convex ring 33 of the timer 3. The convex ring 33 is used to limit the limiting sheath 4 from sliding out by itself. At this time, the lamp holder 1 is powered on, the ultraviolet lamp 2 and the timer 3 work at the same time, the timer 3 starts timing and the indicator light 34 lights up green. When the time counted by the timer 3 reaches the expected normal working life of the ultraviolet lamp 2, the indicator light 34 lights up red to remind.
