Some embodiments of the present disclosure provide an air conditioning device. As shown in FIG. The shell 2000, the air conditioning device 1 realizes the air purification function through the negative ion generator 1000.

The present disclosure does not limit the installation position of the negative ion generator 1000 on the air conditioning device 1 , as long as the air purification function can be realized.

Referring to FIGS. 1 and 3 , the negative ion generator 1000 includes an emitter electrode part 100 , a driving part 200 and a power supply part 300 .

For the convenience of description, the components are mainly described in the orientations shown in FIG. 1 below. The orientation of the drive unit 200 is at the top, the orientation of the power supply unit 300 is at the bottom, the orientation of the main controller 400 is at the left, and the orientation of the emitter electrode unit 100 is at right.

As shown in FIG. 6 , the emitter electrode part 100 includes an end cap 140 and a plurality of emitter electrodes 110 . The end cap 140 and the plurality of emitter electrodes 110 are connected to the driving unit 200 . The emitter electrode 110 includes an emitter electrode body 112 , and the emitter electrode body 112 is in the shape of a fan blade. For example, a plurality of emitter electrodes 110 are arranged counterclockwise around the central axis of the driving part 200 to form a fan structure.

The material of the emitter electrode 110 is metal conductive material, such as copper, aluminum alloy and the like. The number of emitter electrodes 110 is set according to actual needs, and may be 2 to 6 pieces.

The emitter electrode 110 includes an emitter electrode body 112 and a plurality of first emitter tips 120 connected to the emitter electrode body 112 . Each blade of the emitter electrode body 112 has a first side 1121, a second side 1122 and a third side 1123, the first side 1121 and the second side 1122 are opposite in the direction of rotation, and the third side 1123 is The free end of the fan blade. The plurality of first emitter tips 120 are located on at least one of the first side 1121 , the second side 1122 and the third side 1123 of the emitter electrode body 112 . For example, as shown in FIG. 6, the first emitter tip 120 is located on the first side 1121 (such as the leeward side) of the emitter electrode body 112, and as shown in FIG. On the side 1123, in this way, when the emitter electrode part 100 rotates in a predetermined direction (such as counterclockwise), the first emitter tip 120 can effectively ionize with the air to ensure the generation of negative ions, which are located on different emitter electrode bodies 112 The multiple first emitting tips 120 can ionize different parts of the gas to generate negative ions, so that the negative ions can be distributed evenly.

The emitter electrode part 100 combines the emitter electrode that produces negative ions and the fan system that provides wind power into one, and the emitter electrode part 100 that generates negative ions is designed as a fan structure, releasing a large amount of negative ions into the air in the form of corona discharge. With the wind force generated by the high-speed operation of the electrode part 100, the negative ions will not accumulate around the emitter electrode part, but will be directed to a farther place, thereby increasing the production of negative ions and improving the air purification effect.

In addition, since the ions are negatively charged by obtaining excess electrons to form negative ions, when the emitter electrode part 100 operates at a high speed, a strong centrifugal force is generated, and strong frictional contact occurs between the first emitter tip 120 and the air, which reduces the flow of electrons from the first emitter tip 120 to the air. The work function released by the first emitting tip 120 makes it easier for electrons to be released from the first emitting tip 120, increasing the amount of negative ions released. The emitter electrode part 100 is a unipolar negative high-voltage emitter without a ground electrode, so the ozone content is extremely low.

As shown in FIG. 1 , FIG. 3 and FIG. 5 , the driving unit 200 is connected to the emitter electrode unit 100 and configured to drive the emitter electrode unit 100 to rotate. The driving part 200 includes a motor 210 , a force transmission part 270 , a first power source 240 and a housing 250 .

The motor 210 is coupled to a first power source 240 (such as the power source V1 in FIG. 1 ), and the power of the motor 210 is provided by the first power source 240 . The output shaft 211 of the motor 210 is sequentially connected to the force transmission part 270 and the emitter electrode part 100 . The output shaft 211 of the motor 210 transmits the power of the motor 210 to the emitter electrode part 100 through the force transfer part 270 to drive the emitter electrode part 100 to rotate.

For example, according to the room size and usage requirements, the rotation speed of the emitter electrode part 100 can be adjusted through the rotation speed of the motor 210 to adjust the transmission distance of negative ions. When the rotating speed of the emitter electrode part 100 was high, the wind force generated by the emitter electrode part 100 was relatively large, so that the transmission distance of negative ions was longer; when the rotating speed of the emitter electrode part 100 was low, the wind force generated by the emitter electrode part 100 was smaller Make the transmission distance of negative ions shorter.

The drive unit 200 includes a multi-speed adjustable speed mode to adjust the speed of the emitter electrode unit 100 in multiple levels. stalls. For example, the driving part 200 can provide high, medium and low speeds to make the emitter electrode part 100 move at different speeds, so as to transmit negative ions to three different distances: far, middle and near.

In some embodiments, the driving part 200 also includes a stepless adjustment mode, that is, the driving part 200 has no gear limit, and for any attainable rotating speed of the driving part 200, the rotating speed of the emitter electrode part 100 can be adjusted arbitrarily through a switch such as a knob .

As shown in FIG. 5 , the force transmission part 270 includes a conductive part 261 and an insulating bearing 230 .

The conductive part 261 includes a conductive connecting rod 220, the material of the conductive connecting rod 220 is a metal conductive material, the first end of the conductive connecting rod 220 (as shown in the right end in Figure 5) is fixedly connected with the end cover 140, and the material of the end cover 140 is insulating Material.

The second end of the conductive connecting rod 220 (the left end in FIG. 5 ) is connected to the first end of the insulating bearing 230 . The second end of the insulating bearing 230 is connected with the output shaft 211 of the motor. The material of the insulating bearing 230 is an insulating material. Since the material of the output shaft 211 of the motor is metal conductive material, the insulating bearing 230 can prevent the negative high voltage on the conductive connecting rod 220 from causing damage to the motor 210 . By providing the force transmission part 270 , the emitter electrode part 100 can release negative ions during rotation, and blow the negative ions to a distance corresponding to the rotation speed of the driving part 200 .

The material of the housing 250 is insulating material. The inside of the casing 250 defines an accommodating space 251, the motor 210 and the insulating bearing 230 are arranged in the accommodating space 251 of the casing 250, and the first end of the casing 250 (as shown in the right end in FIG. The first through hole 252 and the second end of the casing 250 (the left end in FIG. 5 ) are open for the power line to pass through to provide power to the motor 210 .

The power supply part 300 is coupled to the emitter electrode part 100 , and the power supply part 300 is configured to provide negative voltage (eg, negative high voltage) to the emitter electrode part 100 . As shown in FIGS. 1 and 5 , the power supply unit 300 includes a transformer 310 , a second power supply 320 (such as the power supply V2 in FIG. 1 ), connection terminals 330 and conductive bearings 340 . A first end of the transformer 310 (for example, a horizontal output transformer) is coupled to the second power supply 320 , and a second end of the transformer 310 is coupled to the connection terminal 330 . The transformer 310 is configured to step up the negative voltage of the second power source 320 .

The output negative voltage of the transformer 310 can be a DC negative high voltage to increase the amount of negative ions released; it can also be a high-frequency DC pulse negative high voltage. Under the high-frequency DC pulse negative high voltage, the negative ion generation of the emitting electrode part 100 is higher.

The second power supply 320 can be commercial power or low-voltage direct current. For example, after the second power supply 320 supplies power to the transformer 310, the transformer 310 converts the voltage of the second power supply 320 into a negative high voltage of 3KV to 10KV.

The conductive bearing 340 is disposed in the first through hole 252 , the conductive bearing 340 includes a second through hole 341 , the conductive connecting rod 220 passes through the second through hole 341 , and the conductive connecting rod 220 is coupled to the conductive bearing 340 . The conductive bearing 340 is coupled with the connection terminal 330 . The transformer 310 is coupled to the conductive bearing 340 through the terminal 330 , for example, the terminal 330 is coupled to the conductive bearing 340 by soldering. The conductive link 220 transmits the negative high voltage of the transformer 310 to the emitter electrode part 100 . That is, the conductive connecting rod 220 also plays the role of transmitting negative high voltage while transmitting power.

As shown in FIG. 1 , FIG. 3 and FIG. 4 , the connection terminal 330 includes a horizontal portion 331 and a vertical portion 332 connected to the horizontal portion, and the horizontal portion 331 is substantially perpendicular to the vertical portion 332 . The horizontal portion 331 is connected to the circumferential surface of the conductive bearing 340 , and the connection terminal 330 is coupled to the transformer 310 through the vertical portion 332 .

The negative high voltage generated by the transformer 310 is transmitted to the emitter electrode 110 through the connection terminal 330 , the conductive bearing 340 and the conductive connecting rod 220 , and finally a corona discharge occurs from the first emitter tip 120 to generate negative ions.

As shown in Figure 1, Figure 2 and Figure 5, the working process of the negative ion generator 1000 is: the second power supply 320 supplies power to the transformer 310, the transformer 310 loads the negative high voltage onto the emitter electrode 110, and the first power supply 240 supplies power to the motor 210 , the motor 210 drives the emitter electrode 110 to rotate, and the air around the emitter electrode 110 begins to flow from the emitter electrode part 100 near the motor 210 to the side away from the motor 210, for example, in FIG. 2, it flows from left to right, and the air on the left side The air has no charge, and when the air flows through the emitting electrode 110, the radius of curvature at the first emitting tip 120 is relatively small, causing the electric field intensity around the first emitting tip 120 to be relatively high, and the electrons escape from the first emitting tip 120 and are connected with the first emitting tip 120. The left side moves to the air around the first emitting tip 120 and collides to generate negative ions. Since the emitting electrode 110 is rotating at a high speed, the air can be driven to flow rapidly to the right, and the generated negative ions are quickly transported to the predetermined distance on the right. , the uncharged air on the left is continuously replenished, thus forming a cycle and continuously releasing negative ions.

In some embodiments, as shown in FIG. 1 , the main controller 400 is coupled to the driving unit 200 and the power unit 300 respectively. For example, the main controller 400 is coupled with the first power supply 240 to control the conduction or disconnection between the first power supply 240 and the motor 210; the main controller 400 is coupled with the second power supply 320 to control the second power supply 320 Conduction or disconnection with the transformer 310.

After the main controller 400 receives the first instruction (for example, an air purification instruction), the main controller 400 controls the first power supply 240 and the second power supply 320 to supply power to the motor 210 and the transformer 310 respectively, thereby realizing the rotation of the emitter electrode part 100. At the same time release negative ions.

After the main controller 400 receives the second instruction (for example, stop the air purification instruction), the main controller 400 controls the first power supply 240 and the second power supply 320 to stop supplying power to the motor 210 and the transformer 310 respectively, and the emitter electrode part 100 stops rotating. , and at the same time, the emitter electrode part 100 stops releasing negative ions. The above-mentioned first instruction and second instruction may be issued by a control device such as a remote controller of the air conditioning device 1 .

In some embodiments, the same air conditioning device 1 can be provided with multiple emitter electrode parts 100, and the main controller 400 controls the multiple emitter electrode parts 100 to be energized according to air quality conditions and the number of people. The worse the air quality is, the more the main controller 400 controls the number of emitter electrode units 100 to be activated, so as to improve the purification efficiency. When the number of people is smaller, the main controller 400 controls the output voltage of the power supply unit 300 to increase to increase the amount of negative ions and ozone generated by the emitter electrode unit 100 .

For example, if the pollution in the room is serious, or the room needs to be cleaned quickly, the main controller 400 can control multiple emitter electrode parts 100 to be energized at the same time to improve the purification efficiency; if the pollution in the room is relatively light, the main controller 400 can A part of the emitter electrode portions 100 in the plurality of emitter electrode portions 100 is controlled to be energized so as to reduce energy consumption while ensuring the purification effect.

The air supply direction of each emitter electrode part 100 can be adjusted. For example, the emitter electrode part 100 is turned from one wall in the room to another wall, so as to deliver negative ions to different areas in the room according to needs, and improve the effective utilization of negative ions. .

Each emitter electrode unit 100 can be equipped with a drive unit 200 and a power supply unit 300 respectively, each emitter electrode unit 100 is independent of each other, and the rotation speed and negative high voltage of each emitter electrode unit 100 can be controlled separately according to requirements. Alternatively, a plurality of emitter electrode parts 100 share a set of driving part 200 and power supply part 300, so that the structure and control logic of the air conditioning device 1 can be simplified and the cost can be reduced.

In some embodiments, the output voltage of the power supply unit 300 is controlled by the main controller 400 to adjust the amount of negative ions and ozone generated by the emitter electrode unit 100 .

When there is no one in the room, the main controller 400 adjusts the output voltage of the power supply unit 300 to a high level (that is, the output voltage of the power supply unit 300 is relatively large), and the amount of ozone generated by the emitter electrode unit 100 is greater than the amount of negative ions at this time, which improves the room temperature. The effect of internal microbial purification.

When there are people in the room and the air needs to be sterilized, the main controller 400 adjusts the output voltage of the power supply unit 300 to a mid-range (that is, the output voltage of the power supply unit 300 is medium). The amount of ozone and negative ions play a major role in air purification. The amount of ozone is within the range that does not affect human health. Ozone assists negative ions in air purification.

When the user needs to promote blood circulation, the main controller 400 adjusts the output voltage of the power supply unit 300 to a low level (that is, the output voltage of the power supply unit 300 is relatively small), at this moment, the voltage intensity is not enough to generate ozone, and the emitter electrode unit 100 only produces negative ions .

In some embodiments, as shown in FIG. 7 , the negative ion generator 1000 further includes a ground electrode part 500 .

Referring to FIG. 11 , the ground electrode part 500 is provided around the outer periphery of the emitter electrode part 100 .

A plurality of first emitter tips 120 are located on the third side 1123 of the emitter body 112 , the ground connection terminal 520 is disposed on the outer wall of the ground electrode body 530 , and the ground electrode part 500 is grounded through the ground connection terminal 520 .

When the driving part 200 drives the emitter electrode part 100 to rotate, the ground electrode part 500 is fixed.

Of course, the ground electrode part 500 can also be rotated and the emitter electrode part 100 is fixed, as long as the relative movement between the ground electrode part 500 and the emitter electrode part 100 can be realized.

In some embodiments, referring to FIG. 9 and FIG. 15 , the driving part 200 further includes an installation stand 260 . The material of the mounting table 260 is an insulating material.

The mounting table 260 also includes a ventilation hole 263, and the ventilation hole 263 is arranged through the mounting table body 264 along the thickness direction of the mounting table body 264.

When the emitter electrode part 100 rotates relative to the ground electrode part 500, the distance between the first emitter tip 120 and the second emitter tip 510 changes continuously to form a high-frequency pulsed electric field between the emitter electrode part 100 and the ground electrode part 500 The emitter electrode part 100 is the negative pole of the high-frequency pulsed electric field, and the ground electrode part 500 is the positive pole of the high-frequency pulsed electric field.

In this way, negative ions can be released while rotating the emitter electrode part 100 .

Step 200, when the main controller 400 receives the second instruction (for example, stop the air purification instruction), the main controller 400 controls the driving part 200 to stop driving the emitter electrode part 100 and controls the power supply part 300 to stop supplying negative energy to the emitter electrode part 100. pressure. In this way, the rotation of the emitter electrode part 100 can be stopped and the release of negative ions can be stopped.

In some embodiments, as shown in FIG. 17 , step 100 includes step 110 .

Step 110, after the main controller 400 receives the first instruction (for example, an air purification instruction), the main controller 400 controls the first power supply 240 and the second power supply 320 to supply power to the motor 210 and the transformer 310 respectively. In this way, negative ions can be released while rotating the emitter electrode part 100 .

In some embodiments, step 200 includes step 210 .

Step 210, when the main controller 400 receives the second instruction (for example, stop air purification instruction), the main controller 400 controls the first power supply 240 and the second power supply 320 to stop supplying power to the motor 210 and the transformer 310 respectively. In this way, the emitter electrode part 100 stops rotating, and at the same time, the emitter electrode part 100 stops releasing negative ions.
