Referring to fig. 1 to 3, an ultraviolet germicidal lamp for a locker according to some embodiments of the present utility model includes a housing 100, a lamp tube 120, a ballast 130, a control board, and a gate switch 140. The housing 100 has an inner cavity, and the upper side, the front side, and the rear side of the housing 100 are provided with through holes 110. Lamp 120 is located within housing 100, and lamp 120 is configured to emit ultraviolet light for sterilization. A ballast 130 is located in the housing 100, the ballast 130 being electrically connected to the lamp 120. A control board is located within the housing 100, the control board being electrically connected to the ballast 130. The door control switch 140 is used to detect the open and closed states of the cabinet doors of the locker.

When a user opens the locker, the door control switch 140 detects that the cabinet door of the locker is turned from the closed state to the open state, the door control switch 140 feeds back an electric signal to the control board, and the control board receives the signal from the door control switch 140 and then controls the ballast 130 to be powered off, so that the lamp tube 120 is controlled to be extinguished, and ultraviolet rays emitted by the lamp tube 120 are prevented from injuring a human body accidentally.

When the user closes the locker, the door control switch 140 detects that the cabinet door of the locker is changed from the open state to the closed state, the door control switch 140 feeds back an electric signal to the control board, and the control board receives the signal from the door control switch 140 and then controls the ballast 130 to be electrified, so that the lamp tube 120 is controlled to be opened, and the lamp tube 120 emits ultraviolet rays to sterilize objects in the locker.

It should be noted that, in the present embodiment, the housing 100 is a cuboid, and may be adjusted to a sphere, a prism, etc. according to the requirement; the number of lamps 120 may be adjusted as desired.

It should be noted that, the lamp 120 in this embodiment adopts short wave UVC with a wavelength of 200-275 nm, which is also called short wave sterilization ultraviolet. It has the weakest penetration ability and cannot penetrate most transparent glass and plastics. Short wave ultraviolet rays contained in sunlight are almost completely absorbed by the ozone layer, and are absorbed by the ozone layer before reaching the ground. Degree of injury to human body: UVC in nature is absorbed by ozone layer without reaching the ground, and has negligible effect on skin, but short wave ultraviolet rays are harmful to human body, and can not directly irradiate human body. If the irradiation is direct, the skin can be burned by short-time irradiation, and skin cancer can be caused by long-term or high-intensity irradiation. UVC application field: the ultraviolet lamp 120130 emits ultraviolet rays of UVC short wave. Short wave ultraviolet rays are widely used in hospitals, air conditioning systems, sterilizing cabinets, water treatment facilities, water dispensers, sewage treatment plants, swimming pools, food and beverage processing and packaging facilities, food factories, cosmetic factories, dairy factories, breweries, beverage factories, bakeries, refrigerating rooms, and the like.

Further, the ultraviolet sterilizing lamp for the locker further comprises a timing switch 150, the timing switch 150 is electrically connected with the control board, and the timing switch 150 is used for controlling the working time of the lamp tube 120. The user can control the working time of the lamp 120 after lighting through the timing switch 150, for example, when the user closes the locker, the gating switch 140 detects that the cabinet door of the locker is turned from the open state to the closed state, the gating switch 140 feeds back an electric signal to the control board, the control board controls the ballast 130 to be electrified after receiving the signal from the gating switch 140, thereby controlling the lamp 120 to be started, the lamp 120 emits ultraviolet rays to perform sterilization treatment on objects in the locker, and when the working time of the lamp 120 reaches the time designated by the timing switch 150, the control board controls the ballast 130 to be powered off, thereby controlling the lamp 120 to be extinguished.

According to some embodiments of the utility model, the gate switch 140 is a door magnetic switch or a pressure switch.

The door magnetic switch mainly comprises a switch part and a magnet part, wherein the switch part is mainly a normally open reed switch; the magnet part is mainly a permanent magnet with a permanent magnet inside, and is used for providing a stable magnetic field. When the switch portion is very closely spaced from the magnet portion, i.e., the door or window is in a closed state; and when the switch portion is spaced farther from the magnet portion, i.e., the door or window is in an open state.

It should also be noted that the working principle of the pressure switch is as follows: when the pressure in the system is higher than or lower than rated safety pressure, the disc in the sensor instantaneously moves, the switch connector is pushed to be switched on or off through the connecting guide rod, when the pressure is reduced to or increased to a rated recovery value, the disc instantaneously resets, and the switch automatically resets, or simply, when the measured pressure exceeds the rated value, the free end of the elastic element generates displacement, and the switch element is pushed directly or after comparison, so that the on-off state of the switch element is changed, and the aim of controlling the measured pressure is fulfilled. The elastic element adopted by the pressure switch comprises a single-ring spring tube, a diaphragm capsule, a corrugated tube and the like.

According to some embodiments of the present utility model, the structure of the through hole 110 is a mesh structure, which can allow the ultraviolet rays irradiated by the lamp 120 to pass through the housing 100 smoothly, and prevent external impact from damaging the lamp 120.

According to some embodiments of the present utility model, the hidden slot 160 is provided inside the housing 100, and the hidden slot 160 is convenient for accommodating wires, so as to avoid the wires blocking ultraviolet rays.

According to some embodiments of the utility model, the outer wall of the housing 100 is provided with lifting lugs 170, the lifting lugs 170 being used to secure the housing 100 within a locker.

In the description of the present specification, reference to the term "some embodiments" means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the utility model. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples.
