Description

The present invention relates to a portable ultraviolet germicidal lamp, and more particularly, to an ultraviolet germicidal lamp that is provided with a safety switch to prevent ultraviolet rays from being irradiated upward.

A general portable ultraviolet germicidal lamp has a structure in which a power supply unit, a control circuit, and an ultraviolet lamp, which are electrically connected to each other, are usually installed in a single housing. The lamp is controlled to be turned on and off, and an opening corresponding to the ultraviolet lamp is provided in the housing so as to irradiate ultraviolet rays, thereby providing a sterilizing action to the user.

This kind of portable UV germicidal lamp is mainly carried by users and is used for public sanitation facilities (public toilets, etc.)
Before use, the surface of related equipment (such as toilet seats) can be sterilized with ultraviolet rays to prevent the transmission of disease. It can also be used to sterilize food, hands, etc. at any location.
Alternatively, it can be used to sterilize vomit in a room or public place.

Although the ultraviolet rays emitted by UV lamps are harmful if directly irradiated to the human body, this type of portable UV lamp does not have a safety design for this, and the user carelessly irradiates the UV rays directly upward to the head of the human body. Irradiation causes unnecessary injury and needs to be improved.

Furthermore, there is a possibility that the portable UV germicidal lamp may accidentally touch the switch when it is carried (such as when it is in a bag). If the UV germicidal lamp is taken out without the user's knowledge, the ultraviolet light is directly emitted. The human body may be irradiated, and there is a need to improve the switch part. .

JP 2005-323654 A Japanese Patent Laid-Open No. 11-188081 Registered Utility Model No. 3041156 Japanese Utility Model Publication No. 6-75500 Japanese Utility Model Publication No. 1-90544

This invention makes it a main subject to provide the portable ultraviolet germicidal lamp which can prevent that an ultraviolet-ray is irradiated upwards.

Another object of the present invention is to provide a portable ultraviolet lamp capable of preventing the switch from being accidentally turned on when being carried.

In order to solve the above problems, a portable ultraviolet lamp provided with the safety switch of the present invention accommodates and installs a power supply unit, a control circuit and an ultraviolet lamp which are electrically connected to each other in a hollow housing, The on / off of the ultraviolet light is controlled by a switch provided in the control circuit with electric power provided by the power supply unit, and an opening is provided on the bottom of the housing corresponding to the ultraviolet lamp so that the ultraviolet light is irradiated downward. Furthermore, a safety switch is fixed in the housing, and the safety switch is electrically connected to the control circuit. When the housing is tilted at a certain angle, the safety switch shuts off the circuit and turns off the UV lamp, and the UV light is irradiated upward. Do not be.

In order to prevent the portable ultraviolet germicidal lamp from being erroneously operated when being carried, the present invention further provides an indicator lamp in the control circuit, and the indicator lamp is turned on when the switch is on, and the indicator lamp is in the on state. Only when the switch is turned on again can the UV lamp be activated. Accordingly, it is possible to prevent the user from inadvertently touching the switch and starting the ultraviolet germicidal lamp when carrying the ultraviolet germicidal lamp.

When the portable ultraviolet germicidal lamp of the present invention is tilted at a certain angle, the safety switch cuts off the circuit and turns off the ultraviolet lamp, so that the ultraviolet light is not irradiated upward. In addition, the indicator light is turned on when the switch is on, and the ultraviolet light is activated only when the switch is turned on again with the indicator light on, so the user inadvertently touches the switch when carrying the UV germicidal lamp. The problem of starting the UV germicidal lamp can be prevented.

As shown in FIGS. 1 to 4, a portable ultraviolet germicidal lamp having a safety switch according to the present invention includes a power supply unit 2, a control circuit 3 and an ultraviolet lamp 4 which are electrically connected to each other in a hollow housing 1. The power supply unit 2 supplies power, and the on / off state of the ultraviolet lamp 4 is controlled by a switch 31 provided in the control circuit 3.

An opening 11 corresponding to the ultraviolet lamp 4 is provided at the bottom of the housing 1, and when the ultraviolet lamp 4 is activated, ultraviolet rays are irradiated downward, and a grip 12 is provided at a portion away from the opening 11 of the housing 1. Allow the user to grip.

In this embodiment, the power supply unit 2 is a battery unit, and the above-described switch 31 is provided in the housing 1.
It is installed at a location close to the grip 12 on one surface (that is, the upper surface) away from the opening 11 so that the user can easily operate it.

An indicator lamp 32 is further provided in the control circuit 3. The indicator lamp 32 is installed at a location close to the switch 31. The indicator lamp 32 is activated only when the switch 31 is turned on by the control of the control circuit 3. The ultraviolet lamp 4 is activated only when the switch 31 is turned on again in the activated state.

The safety switch 5 is further fixed inside the housing 1 and connected to the control circuit 3. When the housing 1 is inclined at a certain angle, the safety switch 5 shuts off the circuit and turns off the ultraviolet lamp 4, and the ultraviolet rays are upward. To prevent irradiation.

As shown in FIG. 3, the safety switch selected and used in this embodiment is a ball switch.
ch), two electrodes 52, 53 are installed at the bottom of the hollow case 51, and the two electrodes 52,
When a conductive sphere 54 such as a steel ball is installed between 53 and normally, the conductive sphere 54 comes into contact with the two electrodes 52 and 53 and becomes conductive, and when the case 51 is inclined to a certain angle, The conductive sphere 54 separates between the two electrodes 52 and 53 to form a circuit interruption, thereby turning off the ultraviolet lamp 4.

As shown in FIG. 4, when the user uses the ultraviolet germicidal lamp, the user grips the grip 12 and holds the housing 1 with the opening 11 facing downward. Although the user's hand may move in the process of use or the angle may change to some extent depending on the external environment, the state in which the ultraviolet rays emitted from the ultraviolet lamp 4 are generally irradiated downward is maintained. The installation of the safety switch 5 of the present invention can maintain the conduction state even in such a use state, and the ultraviolet germicidal lamp is normally used.

However, when the inclination angle of the ultraviolet germicidal lamp is too large (exceeds the α angle shown in FIG. 4), there is a possibility that the ultraviolet light emitted from the ultraviolet lamp 4 may be irradiated upward, and thus the safety switch 5 used in the present invention. At this angle, a conductive sphere 5 such as a steel ball in the safety switch 5
4 was designed to roll out from between the two electrodes to form a circuit break and turn off the ultraviolet lamp 4. By doing so, it can be ensured that the ultraviolet rays emitted from the ultraviolet lamp 4 are not irradiated upward, and the possibility of causing damage to the human body can be prevented.

Since the UV germicidal lamp of the present invention is a portable design, there is a possibility that the user may carry the UV germicidal lamp in a bag when carrying it. These items may hit the switch 31 of the ultraviolet germicidal lamp. In order to prevent the UV germicidal lamp from being accidentally activated in the bag, the design of the present invention is such that the indicator lamp 32 is activated only when the switch 31 is turned on under the control of the control circuit 3, and the indicator lamp 32 is not activated. The ultraviolet lamp 4 can be activated only when the switch 31 is turned on again in the activated state, thereby preventing the ultraviolet germicidal lamp from being activated by careless contact when carrying the ultraviolet germicidal lamp.
