Abstract

An ultraviolet ray detector, comprising a casing and a circuit board. A light sensor and a light intensity indicator are provided on the circuit board. Since the light sensor capable of sensing external ultraviolet ray intensity is provided on the circuit board, during use, the light sensor senses external ultraviolet ray intensity, and the external ultraviolet ray intensity is visually reported to a user via the light intensity indicator.

Description

Ultraviolet detector

[Technical Field]

The present invention relates to the field of daily necessities, and more particularly to an ultraviolet detector. 【Background technique】

With the development of science and technology and the improvement of living standards, people's requirements for beauty are getting higher and higher. Due to the increasingly severe destruction of the ozone layer, the amount of ultraviolet radiation received by the ground increases. When people go out, they usually use sunscreen to reduce ultraviolet radiation. The sunscreen effect of sunscreen is graded. Different UV intensity uses different grades of sunscreen. Frost, people usually measure the intensity of external ultraviolet light according to their life experience, so they can apply different levels of sunscreen. Because different people have different experiences, if the intensity of external ultraviolet light is too low, the sunscreen with lower sunscreen level will cause skin. Sunburn, if it is too high, it measures the intensity of ultraviolet rays outside the sun. It is also harmful to the user's skin.

[Summary of the Invention]

The technical problem to be solved by the present invention is to provide an ultraviolet detector capable of automatically detecting the intensity of ultraviolet rays from the outside.

The object of the present invention is achieved by the following technical solutions:

An ultraviolet detector includes a housing, a circuit board, and a light sensor and a light intensity indicator are disposed on the circuit board.

Preferably, the light sensor is a photoresistor. Photoresistors are a specific implementation of a light sensor.

Preferably, the light intensity indicator is an ultraviolet intensity indicator. By setting the UV intensity indicator, the user can easily know the current UV intensity.

Preferably, there are five ultraviolet intensity indicator lights, and each of the ultraviolet intensity indicators represents different ultraviolet intensity.

Preferably, the power board indicator is further disposed on the circuit board. Preferably, the circuit board is provided with a button switch, and the button switch is located at one side of the ultraviolet intensity indicator.

Preferably, an intensity mark is provided on the housing at a position corresponding to the ultraviolet intensity indicator. Set the intensity mark to make it easy for the user to know the intensity of the UV light.

Preferably, the ultraviolet detector further comprises a speaker. When the external UV intensity is at the highest level, the speaker alarms.

Preferably, the speaker is soldered to the circuit board. This is the specific installation method of the speaker.

Preferably, the housing is provided with a sound hole. A sound hole is provided in the housing to make the sound of the speaker brighter.

In the invention, since the light sensor capable of sensing the intensity of the external ultraviolet light is disposed on the circuit board, the light sensor senses the external ultraviolet light intensity, and intuitively tells the user the intensity of the ultraviolet light through the light intensity indicator.

【detailed description】

The invention will now be further described with reference to the drawings and preferred embodiments.

As shown in FIG. 1 and FIG. 2, the ultraviolet detector of the embodiment includes a casing and a circuit board, and the circuit board is provided with a light sensor and a light intensity indicator. The circuit board is disposed inside the casing, and the light sensor can receive external light through the through hole provided in the casing, wherein the light sensor is a photoresistor. The light intensity indicator is an ultraviolet intensity indicator. Photosensitive resistors are a specific embodiment of a light sensor. By setting the UV intensity indicator, the user can easily know the current UV intensity. In the invention, since the light sensor capable of sensing the intensity of the external ultraviolet light is disposed on the circuit board, the light sensor senses the external ultraviolet light intensity when used, and intuitively tells the user the intensity of the ultraviolet light through the light intensity indicator. The housing of the ultraviolet detector of this embodiment includes an upper case 1 and a lower case 2, and the upper case and the lower case are fixed by heat fusion. There are five UV intensity indicators (not shown), each of which represents a different UV intensity. There are five indicator holes on the housing, and the indicator holes correspond to the positions of the indicators. A power indicator light is also provided on the board. A button switch 3 is disposed on the circuit board, and the button switch is located at one side of the ultraviolet intensity indicator. The ultraviolet detector of this embodiment further includes a speaker. When the external UV intensity is at the highest level, the speaker alarms. The speaker is soldered to the board. This is the specific installation method of the speaker. A sound hole is provided on the housing. A sound hole 4 is provided in the casing to make the sound of the speaker brighter. The power source for ultraviolet detection of the present embodiment comes from a battery provided on the casing.

An intensity mark (not shown) is provided on the housing at a position corresponding to the ultraviolet intensity indicator. Set the intensity mark to make it easy for the user to know the intensity of the UV light. Among them, 5 UV intensity indicators are Level 1, 2, 3, 4, and 5, of which Level 1 represents: It has almost no effect on human skin, it is a safe radiation range, and no special precautions are required when going out (1) The level indicator also serves as a power indicator. Level 2 representative: A slight influence on the human skin, but still a safer range of radiation, no special precautions are required. Level 3: It has a certain influence on the skin of the human body. For outdoor activities, apply sunscreen, sun hat and sun mirror to avoid prolonged exposure. Level 4 representative: The skin is prone to burns. When going out, pay attention to the sunscreen that lasts longer. Wear a sun hat and sunglasses. Try to walk in a cool place to avoid burning the skin. Level 5 Representative: It will burn the skin. Try to avoid outdoor activities and avoid direct sunlight.

When using, press the button switch to place the UV detector outside, and the UV intensity indicator will show the current UV intensity. If the external UV intensity is at the highest level, the speaker alarms. When the level 1 indicator light dims, or the alarm sound becomes light, the battery set on the housing should be replaced.

The above is a further detailed description of the present invention in conjunction with the specific preferred embodiments. It is not intended that the specific embodiments of the invention are limited to the description. It will be apparent to those skilled in the art that the present invention can be made without departing from the spirit and scope of the invention.
