Description

Built-in air purifier

This creation is related to air purifiers, especially a built-in air purifier.

Press, with the rapid development of industrial technology, haze and air pollution have become extremely serious in recent years, and suspended particles in the air have caused great impact and harm to human health. Therefore, air purifiers have become one of the essential products in many places. ; The main working principle of the conventional air purifier is to use the motor to drive the fan to attract external air into the body. The air sucked into the body passes through the pre-filter, powerful filter and activated carbon filter in sequence. It filters the air layer by layer to achieve the effect of air purification. Depending on the installation location, it is mainly divided into floor-standing type and square grille type. Among them, although the floor-standing type has the advantage of being easy to install, its disadvantage is that it is large in size and The air inlet of the filter is easily blocked by objects around the environment. The HEPA filter is a consumable material. If the filter is too dense, the motor will not be able to absorb air and the noise will be too loud. As for the square grille type, as shown in Figure 1, it is installed on the ceiling. The light steel frame 100 includes an air inlet device 1 and an air outlet device 2. The air inlet device 1 is composed of a coarse filter and an exhaust motor, and the air outlet device 2 is composed of a fan and a filter device. The air inlet device 1 and the air outlet device 2 are connected by an air duct 3, thereby achieving the effect of circulating filtration and purifying the air. Although the traditional square grille type air purifier has It has the advantage of not occupying space, but its disadvantage is that the installation cost is too high. The air inlet device 1 and the air outlet device 2 need to be equipped with a sealed air duct 3, which makes the construction cost and installation cost too high. In addition, whether it is floor-standing or square For grille-type air purifiers, the internal filters need to be frequently disassembled, cleaned or replaced in order to maintain the filtering effect of the air purifier at its best and reduce energy consumption. However, frequent disassembly, cleaning or replacement of the filters is not practical. It is quite troublesome, extremely time-consuming and labor-intensive, and inconvenient to use.

Therefore, after observing the above shortcomings, the creator of this case believed that there was a need to improve the existing air purifiers, and thus the invention came into being.

The main purpose of this invention is to provide a built-in air purifier that can avoid occupying indoor floor space and has the advantages of convenient construction. It can also effectively achieve dust removal and sterilization, and has the effect of purifying indoor air.

In order to achieve the above purpose, the built-in air purifier provided by this invention has a body, the body has a closed cavity with an opening in the front, so that an accommodation space is formed inside the body, and the body is on both sides. Each has a fixed elastic piece to fix the main body on the hole in the ceiling; an air guide plate is fixed in front of the main body, and a receiving seat is protruding from the inner surface of the air guide plate so that the air guide plate can The seat is located in the accommodation space of the main body, wherein the air guide plate is provided with a plurality of air inlet holes on the outer periphery of the accommodation seat, and the air guide plate is provided with a plurality of air outlet holes on the inside of the accommodation seat; 1. A circulation fan is fixedly installed in the accommodation base, and the positions of the air outlets correspond exactly to the circulation fan; a circuit board is installed in the accommodation space of the body, and the circuit board includes a main Control circuit and a negative high-voltage circuit, the negative high-voltage circuit can provide negative high voltage; at least one high-voltage discharge needle plate is installed in the receiving seat of the air guide plate and is located in front of the circulation fan, the high-voltage discharge needle The board is respectively provided with a discharge pin corresponding to the air outlet holes, and the discharge pin is electrically connected to the circuit board.

A decorative cover 70 is provided in front of the air guide plate 20 . The decorative cover 70 is a hollow cover body, so that the circulating air can pass through the decorative cover 70 smoothly.

In order to further understand the structural characteristics, technical means and expected effects of this creation, the working principle of this creation is described here. I believe that this will lead to a more in-depth and specific understanding of this creation, as follows:

Please refer to Figure 6, which is a circuit block diagram of a preferred embodiment of the present invention. When the present invention is powered on, the air guide plate 20 is provided with an air inlet 22 and passes through the air inlets 22 in the body 10. The air duct is formed, so the indoor air can be sucked into the main body 10 through the built-in circulation fan 30, introduced into the high-voltage discharge needle plate 60 through the air duct, and finally released to the air outlet hole 23 of the air guide plate 20. Since the high-voltage discharge needle plate 60 generates a fixed-frequency switching signal by the MCU, and adjusts the voltage of the output high voltage in a PWM manner, it converts DC 5V to AC high voltage through the MOS tube under the isolation transformer, and then goes through a multi-stage voltage doubling method. The needle tip on the high-voltage discharge needle plate 60 generates high-voltage plasma. The high-voltage discharge needle plate 60 provides a discharge path, thereby generating high-concentration nanoscale negative oxygen ions. The high-voltage plasma plasma generates high-concentration negative oxygen ions. Negative oxygen ions are at the nanometer level and are extremely easy to completely cover dust. Starting from PM1.0, the coating reaction begins. The dust snowballs and gets bigger and bigger, and finally falls to the ground. The dust reaction sequence is PM1.0→ PM2.5→PM10, in addition, negative oxygen ions have a negative charge, while the surface of bacteria usually has a positive charge. This results in a charge interaction between the negative oxygen ions and the bacteria, causing them to attach to the bacterial surface. This will interfere with the structure and function of bacteria, thereby inhibiting their growth and reproduction. Therefore, the circulation fan 30 continuously circulates the indoor air through the air duct formed in the body 10 and the high-voltage discharge needle plate 60, and the high-voltage plasma is generated High-concentration nano-negative oxygen ions coat indoor dust and bacteria and destroy cell walls. The high-concentration negative oxygen ions generated by the high-voltage plasma plasma will coat dust PM2.5 and bacteria in the indoor air. It is destroyed and eliminated, and finally falls on the floor, thereby achieving dust removal and sterilization, and has the effect of purifying indoor air.

After actual testing by the Guangdong Provincial Microbial Testing Center in Mainland China, this product's dust removal rate and bacteriostatic rate can reach over 99%.

Hereby, the characteristics of this creation and the expected effects it can achieve are stated as follows:

1. Easy to install.

2. The air inlet and outlet are both in the same device, so the cost is low.

3. Electronic filter method, using plasma for sterilization and dust removal, no consumables.

4. The size of the device is the same as that of the LED lamp and can be interchanged with the LED lamp at any time, eliminating the need for digging holes again.

5. Low cost.

6. Does not occupy ground space.

7. The installation quantity can be appropriate according to the size of the square footage, without space restrictions.

To sum up, this invention has excellent practicality among similar products. At the same time, after searching the technical information about this type of structure at home and abroad, no similar structure has been found in the literature. Therefore, This invention has indeed met the requirements for a new patent, and an application must be filed in accordance with the law.

However, the above is only one of the best possible embodiments of this invention. Therefore, all equivalent structural changes made by applying the description of this invention and the patent application scope should be included in the patent scope of this invention.
