Abstract

A negative ion liquid crystal television is a liquid crystal television, and a negative ion generator is arranged inside the liquid crystal television. The negative ion generator body is a specially designed DC-AC-DC boost circuit, and its DC power input end is connected to the DC power output end of the power converter (AC-DC power frame) of the standard component in the liquid crystal television, and its output end is a metal tip, and the metal tip is placed outside the liquid crystal television casing. This device can purify and refresh the air, so that people watching TV around can keep a happy mood at any time and improve fatigue.

Description

A Negative Ion LCD TV

technical field

The utility model relates to a liquid crystal television, in particular to a liquid crystal television with a negative ion generator.

Background technique

Recently, with the improvement of people's living standards, health-oriented products are becoming more and more diversified. In terms of air purification, there are special negative ion air purifiers, and there are also small negative ion air purifiers connected to the USB port of the computer, all of which use high-voltage discharge to generate negative ions. Existing negative ion air purifiers are all machines that operate independently, so they take up a lot of space when used, and users often forget to turn on the air purifier, resulting in poor air quality in the living room or room. The existing high-voltage discharge anion air purifier cannot be installed in the LCD TV due to insufficient stability of the high-voltage module and too large size. In addition, South Korea's Samsung Group has introduced an anion liquid crystal display combined with a liquid crystal display in recent years, but the anion generation method in this anion liquid crystal display is to utilize the light of the cathode lamp tube to irradiate the photocatalyst coated on the liquid crystal screen, and after receiving the light by the photocatalyst, Negative ions are produced by energy excitation, but the disadvantage is that there are very few negative ions per unit volume. If a large amount of negative ions are needed, the characteristics of the photocatalyst must be improved or the energy of irradiation must be enhanced, which will inevitably waste a lot of resources.

Utility model content

The utility model provides a negative ion liquid crystal television.

The utility model adopts the following technical scheme: a negative ion liquid crystal television, which is a liquid crystal television, and is characterized in that: the interior of the liquid crystal television is provided with a negative ion generator, and the body of the negative ion generator is a specially designed DC-AC-DC boosting circuit, Its DC power input terminal is connected to the DC power output terminal of the standard component power converter (AC-DC power frame) in the LCD TV. The output terminal is a metal tip, and the metal tip is placed outside the LCD TV casing. .

In order to prevent the metal tip from electric shock to the user, its outer side can be covered with a fence type cover.

After the TV is powered on, the booster circuit of the negative ion generator converts the input direct current (DC) voltage into alternating current (AC) high voltage and then rectifies it to direct current (DC) -4.0kv~-4.5kv, and then the booster circuit The metal tip at the output discharges. The metal tip will generate a large amount of negative ions. After the negative ions are released by the discharge tip, they will scatter around the LCD TV, neutralize the positive ions in the air, purify and freshen the air, so that people around watching TV can maintain a happy mood at any time and improve fatigue. .

Because the negative ion generator is small in size, it can be installed by LCD TV manufacturers as they like, and it is not limited to the existing negative ion generators on the market, so it has a broad market prospect.

Detailed ways

Below with reference to Fig. 1, Fig. 2, Fig. 3 describe in detail the specific embodiment of the present utility model.

A kind of negative ion liquid crystal television, is a liquid crystal television, it is characterized in that: liquid crystal television interior is provided with negative ion generator 1, negative ion generator 1 body is a specially designed DC-AC-DC step-up circuit, its direct current (DC) power supply The input terminal 2 is connected with the direct current (DC) power output terminal 5 or 6 or 7 of the standard component power converter (AC-DC power frame) 4 in the LCD TV, and its output terminal is a metal tip 3, and the metal tip 3 is placed in the LCD TV Outside the casing 8.

In order to avoid the metal tip 3 from electric shock to the user, its outer side can be covered with a fence type cover 9 .

After the TV is powered on, the booster circuit of the negative ion generator 1 converts the input direct current (DC) voltage into alternating current (AC) high voltage and then rectifies it to direct current (DC) -4.0kv~-4.5kv, and then the booster circuit The metal tip 3 at the output end discharges. The metal tip 3 will generate a large amount of negative ions. After the negative ions are released, they will scatter around the LCD TV, neutralize the positive ions in the air, purify and freshen the air, so that people watching TV around can maintain a happy mood at any time and improve fatigue.

The above is a specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, any insubstantial modification of the utility model using this concept is an act of violating the protection scope of the utility model.

Claims (2)
