Some embodiments of the present disclosure provide an air conditioning apparatus, as shown in fig. 1, the air conditioning apparatus 1 may be an air conditioner, a purifier, a fresh air fan, etc., the air conditioning apparatus 1 includes a negative ion generator 1000, a main controller 400, and a casing 2000, and the air conditioning apparatus 1 implements an air purifying 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 apparatus 1 as long as the air purifying function can be achieved.

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

For convenience of description, the following description will mainly be made with respect to the orientation shown in fig. 1, in which the driving unit 200 is located above, the power unit 300 is located below, the main controller 400 is located left, and the emitter electrode unit 100 is located 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 part 200. The emitter electrode 110 includes an emitter electrode body 112, and the emitter electrode body 112 has a fan blade shape, for example, a plurality of emitter electrodes 110 are arranged counterclockwise around a central axis of the driving part 200, so as to form a fan structure.

The material of the emitter electrode 110 is a metal conductive material such as copper, aluminum alloy, etc. The number of the emitter electrodes 110 may be 2 to 6 sheets according to actual needs.

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 fan 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 being opposite in the rotation direction, and the third side 1123 being the free end of the fan blade. The plurality of first emitter tips 120 are located on at least one of the first, second and third sides 1121, 1122 and 1123 of the emitter electrode body 112. For example, as shown in fig. 6, the first emission tip 120 is located on a first side 1121 (e.g., leeward side) of the emission electrode body 112, and as shown in fig. 11, the first emission tip 120 is located on a third side 1123 of the emission electrode body 112, so that when the emission electrode part 100 rotates in a predetermined direction (e.g., counterclockwise), the first emission tip 120 can effectively ionize with air, ensuring the generation amount of negative ions, and the plurality of first emission tips 120 located on different emission electrode bodies 112 can ionize different portions of gas to generate negative ions, so that the negative ions are uniformly distributed.

The emission electrode part 100 combines an emission electrode generating negative ions and a fan system providing wind power, the emission electrode part 100 generating negative ions is designed into a fan structure, a large amount of negative ions are released into air in a corona discharge mode, and along with the wind power generated by high-speed operation of the emission electrode part 100, the negative ions are not accumulated around the emission electrode part, but are directionally transmitted to a farther place, so that the generation amount of the negative ions is improved, and the air purification effect is improved.

In addition, since ions are negatively charged by obtaining surplus electrons to form negative ions, when the emitter electrode part 100 is operated at high speed, a strong centrifugal force is generated, and a strong frictional touch occurs between the first emitter tip 120 and air, a work function of electrons escaping from the first emitter tip 120 is reduced, electrons are more easily released from the first emitter tip 120, and the amount of negative ions released is increased. The emitter electrode part 100 is a monopolar negative high-voltage emitter, and has no ground electrode, so the ozone content is extremely low.

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

The motor 210 is coupled to a first power source 240 (e.g., power source V1 of fig. 1), and power for the motor 210 is provided by the first power source 240. The output shaft 211 of the motor 210 is connected to the force transmission portion 270 and the emitter electrode portion 100 in this order. The output shaft 211 of the motor 210 transmits power of the motor 210 to the emitter electrode part 100 through the force transmission part 270 to drive the emitter electrode part 100 to rotate.

For example, the rotation speed of the emitter electrode part 100 is adjusted by the rotation speed of the motor 210 according to the room size and the use requirement to adjust the transmission distance of the negative ions. When the rotation speed of the transmitting electrode part 100 is high, the wind power generated by the transmitting electrode part 100 is high, so that the transmission distance of negative ions is long; when the rotation speed of the emitter electrode 100 is low, the wind power generated by the emitter electrode 100 is small, so that the transmission distance of negative ions is short.

The driving part 200 includes a multi-gear rotation speed adjustable mode to perform multi-gear adjustment on the rotation speed of the transmitting electrode part 100, that is, several rotation speeds are preset for the driving part 200 in the multi-gear rotation speed adjustable mode, corresponding to different gears of the driving part 200. For example, the driving part 200 may provide three speeds of high, medium and low, so that the emitter electrode part 100 moves at different speeds, thereby transmitting negative ions to three different distances of far, medium and near.

In some embodiments, the driving part 200 further includes a stepless adjustment mode, that is, the driving part 200 has no gear limitation, and any available rotation speed of the driving part 200 can be adjusted arbitrarily by a switch such as a knob.

As shown in fig. 5, the force transmitting portion 270 includes a conductive portion 261 and an insulating bearing 230.

The conductive portion 261 includes a conductive link 220, a material of the conductive link 220 is a metal conductive material, a first end (e.g., a right end in fig. 5) of the conductive link 220 is fixedly connected to the end cover 140, and a material of the end cover 140 is an insulating material. The portion of the conductive link 220 adjacent to the end cap 140 is connected to the plurality of emitter electrodes 110. A second end (e.g., the left end in fig. 5) of the conductive link 220 is connected to a first end of the insulated bearing 230. A second end of the insulated bearing 230 is connected to the output shaft 211 of the motor. The material of the insulating bearing 230 is an insulating material, and since the material of the output shaft 211 of the motor is a metal conductive material, the insulating bearing 230 can avoid damage to the motor 210 caused by negative high voltage on the conductive connecting rod 220. By providing the force transmitting 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 an insulating material. The housing 250 defines an accommodating space 251 therein, the motor 210 and the insulating bearing 230 are disposed in the accommodating space 251 of the housing 250, a first end (e.g., right end in fig. 5) of the housing 250 is provided with a first through hole 252 through which the conductive link 220 passes, and a second end (e.g., left end in fig. 5) of the housing 250 is opened to pass a power supply line to supply power to the motor 210.

The power supply part 300 is coupled with the emitter electrode part 100, and the power supply part 300 is configured to supply negative pressure (e.g., negative high pressure) to the emitter electrode part 100. As shown in fig. 1 and 5, the power supply part 300 includes a transformer 310, a second power supply 320 (e.g., a power supply V2 in fig. 1), a connection terminal 330, and a conductive bearing 340. A first end of the transformer 310 (e.g., a row 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 boost the negative pressure of the second power source 320.

The output negative voltage of the transformer 310 can be direct current negative high voltage, so that the negative ion release amount is improved; the negative high voltage may be a high-frequency direct current pulse, and the negative ion generation amount of the emitter electrode unit 100 may be higher in the pulse of the high-frequency direct current pulse negative high voltage.

The second power source 320 may be a power frequency commercial power or a low voltage dc, for example, after the second power source 320 supplies power to the transformer 310, the transformer 310 converts the voltage of the second power source 320 into a negative high voltage of 3KV to 10 KV.

The conductive bearing 340 is disposed in the first through hole 252, the conductive bearing 340 includes a second through hole 341, the conductive link 220 is disposed in the second through hole 341, and the conductive link 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 by the connection terminal 330, for example, the connection 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 link 220 functions to transmit negative high voltage while transmitting power.

As shown in fig. 1, 3 and 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.

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 corona discharge is generated by the first emitter tip 120 to generate negative ions.

As shown in fig. 1, 2 and 5, the negative ion generator 1000 operates as follows: the second power supply 320 supplies power to the transformer 310, the transformer 310 loads negative high voltage to the emitter electrode 110, the first power supply 240 supplies power to the motor 210, the motor 210 drives the emitter electrode 110 to rotate, air around the emitter electrode 110 starts to flow from one side of the emitter electrode part 100 close to the motor 210 to one side far away from the motor 210, for example, air on the left side flows from left to right in fig. 2, the air on the left side is uncharged, when the air flows through the emitter electrode 110, the radius of curvature of the first emitter tip 120 is smaller, the intensity of an electric field around the first emitter tip 120 is higher, electrons escape from the first emitter tip 120 and collide with air moving from the left side to the periphery of the first emitter tip 120 to generate negative ions, and because the emitter electrode 110 rotates at a high speed, air can be driven to flow to the right rapidly, the generated negative ions are rapidly transmitted to the position on the right side by a preset distance, and the air on the left side is continuously supplemented by the uncharged air, so that circulation is formed, and the negative ions are continuously released.

In some embodiments, as shown in fig. 1, the master 400 is coupled with the driving part 200 and the power part 300, respectively. For example, the master 400 is coupled to the first power source 240 to control on or off between the first power source 240 and the motor 210; the master 400 is coupled to the second power source 320 to control the connection or disconnection between the second power source 320 and the transformer 310.

When the main controller 400 receives a first instruction (for example, an air purifying 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, so as to realize the rotation of the transmitting electrode part 100 and release negative ions.

When the main controller 400 receives a second instruction (for example, an air purifying stopping 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, the emitter electrode part 100 stops rotating, and the emitter electrode part 100 stops releasing negative ions. The first command and the second command may be issued by a control device such as a remote controller of the air conditioning apparatus 1.

In some embodiments, the same air conditioning apparatus 1 may be provided with a plurality of emitter electrode sections 100, and the main controller 400 controls the plurality of emitter electrode sections 100 to be energized according to the air quality condition and the number of persons. The worse the air quality condition is, the more the main controller 400 controls the number of the starting of the emitter electrode part 100 to improve the purifying efficiency. When the number of persons is smaller, the main controller 400 controls the output voltage of the power supply part 300 to be larger to increase the amount of negative ions and the amount of ozone generated by the emitter electrode part 100.

For example, if the pollution in the room is serious or the room needs to be quickly purified, the main controller 400 can control the plurality of transmitting electrode parts 100 to be simultaneously electrified, so as to improve the purifying efficiency; if the pollution in the room is light, the main controller 400 may control some of the plurality of emitter electrode sections 100 to be energized so that the energy consumption is reduced while the purification effect is ensured.

The direction of the air supply to each emitter electrode segment 100 may be adjusted, for example, the emitter electrode segment 100 may be turned from one wall to another wall in the room, so as to directionally deliver negative ions to different areas in the room as needed, thereby improving the effective utilization of the negative ions.

Each emitter electrode 100 may be respectively provided with a driving part 200 and a power supply part 300, and each emitter electrode 100 is independent from each other, and the rotation speed and the magnitude of the negative high voltage of each emitter electrode 100 are respectively controlled according to the requirement. Or the plurality of emitter electrode units 100 share one set of the driving unit 200 and the power supply unit 300, so that the structure and control logic of the air conditioning apparatus 1 can be simplified and the cost can be reduced.

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

When no one is in the room, the main controller 400 adjusts the output voltage of the power supply part 300 to a high level (i.e., the output voltage of the power supply part 300 is large), and at this time, the amount of ozone generated by the emitter electrode part 100 is greater than the amount of negative ions, thereby improving the effect of purifying microorganisms in the room.

When a person in the room needs to sterilize and disinfect air, the main controller 400 adjusts the output voltage of the power supply part 300 to a middle level (i.e., the output voltage of the power supply part 300 is middle), at this time, the amount of negative ions generated by the emitter electrode part 100 is larger than the amount of ozone, the negative ions play a main role in purifying air, and the ozone amount assists the negative ions in purifying air in a range where the health of the person is not affected.

When the user needs to promote blood circulation, the main controller 400 adjusts the output voltage of the power supply part 300 to a low level (i.e., the output voltage of the power supply part 300 is small), at which time the voltage intensity is insufficient to generate ozone, and the emitter electrode part 100 generates only negative ions.

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

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

Referring to fig. 10 and 11, the ground electrode part 500 includes a ground electrode body 530, a ground connection terminal 520, and a plurality of second emission tips 510, the ground connection terminal 520 and the plurality of second emission tips 510 being connected to the ground electrode body 530, the ground electrode body 530 being of a hollow cylindrical structure. The emitter electrode part 100 is located in the cavity 531 of the ground electrode body 530, the plurality of second emitter tips 510 are disposed on the inner wall surface of the ground electrode body 530 at intervals, and the ends of the plurality of first emitter tips 120 and the ends of the plurality of second emitter tips 510 are disposed correspondingly. The plurality of first emitter tips 120 are located on the third side 1123 of the emitter electrode body 112, the ground connection terminal 520 is disposed on the outer wall surface of the ground electrode body 530, and the ground electrode portion 500 is grounded through the ground connection terminal 520.

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

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

In some embodiments, referring to fig. 9 and 15, the drive section 200 further includes a mounting stage 260. The material of the mounting table 260 is an insulating material. A mounting block 260 is coupled to the first end of the housing 250. The mount 260 includes a mount body 264 and a third through hole 265. The third through hole 265 is provided through the mount body 264 in the thickness direction of the mount body 264. The first end of the conductive link 220 passes through the first through hole 252, the third through hole 265 to a side of the mounting stage 260 remote from the motor 210, and the emitter electrode part 100 is located at a side of the mounting stage 260 remote from the motor 210.

The mount 260 further includes a vent hole 263, and the vent hole 263 is provided through the mount body 264 in the thickness direction of the mount body 264. When the emitter electrode assembly 100 rotates, air around the emitter electrode assembly 100 begins to flow from the side of the mounting table body 264 that is closer to the motor 210 to the side that is farther from the motor 210 through the vent 263.

The ground electrode portion 500 is fixed to the mounting table 260. For example, as shown in fig. 15, the mounting table 260 further includes an annular flange 267 connected to the mounting table body 264, the mounting table body 264 is disc-shaped, the annular flange 267 is coaxial with the mounting table body 264, the ground electrode portion 500 is fixed (e.g., abutted) on the annular flange 267, and the ground electrode portion 500 is coaxial with the emitter electrode portion 100.

The fitting portion 266 includes a fitting hole 262, and the fitting hole 262 is provided through the fitting portion 266 in the thickness direction of the fitting portion 266. The negative ion generator 1000 is easily mounted to the air conditioning apparatus 1 through the fitting hole 262.

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 is continuously changed to form a high-frequency pulse electric field between the emitter electrode part 100 and the ground electrode part 500, the emitter electrode part 100 is a negative electrode of the high-frequency pulse electric field, the ground electrode part 500 is a positive electrode of the high-frequency pulse electric field, and electrons are more easily excited by the high-frequency pulse electric field to be released from the electrode tips, so that the generation amount of negative ions is increased, and the air purifying effect is improved.

The distance between the first and second emission tips 120 and 510 varies as follows:

Referring to fig. 12, when the emitter electrode part 100 and the ground electrode part 500 are relatively rotated and the ends of the first emitter tip 120 and the second emitter tip 510 are facing each other, the electrode distance is a first distance d1, at which the distance between the positive and negative electrodes is the smallest, at which the electric field strength between the emitter electrode part 100 and the ground electrode part 500 is a first electric field strength E1, and the electric field strength between the emitter electrode part 100 and the ground electrode part 500 is the highest.

Referring to fig. 13, the emitter electrode part 100 and the ground electrode part 500 continue to rotate relatively, and the end of the second emitter tip 510 is aligned with the junction of two adjacent first emitter tips 120, the electrode distance is the second distance d2, at which time the distance between the positive and negative electrodes is the largest, the electric field strength between the emitter electrode part 100 and the ground electrode part 500 is the second electric field strength E2, and the electric field strength between the emitter electrode part 100 and the ground electrode part 500 is the lowest.

As the transmitting electrode part 100 and the ground electrode part 500 are continuously rotated relatively, the electric field strength between the transmitting electrode part 100 and the ground electrode part 500 is pulsed back and forth between the first electric field strength E1 and the second electric field strength E2, as shown in fig. 14, generating a pulsed electric field generated by the relative movement between the transmitting electrode part 100 and the ground electrode part 500. In some embodiments, when both the first and second emission tips 120 and 510 are of a saw tooth structure, the generation of negative ions is easily excited.

The size and number of the first and second emission tips 120 and 510 may be set according to actual needs.

In some embodiments, the number of second electrode tips 510 is 2 to 16, for example, the ground electrode portion 500 includes 2, 6, 10, or 16 second electrode tips 510.

As shown in fig. 8, the flow path and the air purifying principle of the air in the negative ion generator 1000 provided with the ground electrode part 500 are similar to those described above, and are not repeated here.

As shown in fig. 16, some embodiments of the present disclosure further provide a method for dynamically generating negative ions of an air conditioning apparatus, including steps 100 and 200.

In step 100, when the main controller 400 receives a first instruction (for example, an air purifying instruction), the main controller 400 controls the driving portion 200 to drive the emitter electrode portion 100 to rotate and controls the power supply portion 300 to provide a negative pressure to the emitter electrode portion 100. In this way, negative ions can be released while rotating the emitter electrode part 100.

In step 200, when the main controller 400 receives the second instruction (for example, the air purifying instruction is stopped), 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 the negative pressure to the emitter electrode part 100. In this way, the emitter electrode segment 100 can be stopped from rotating and releasing negative ions can be stopped.

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

In step 110, after the master controller 400 receives the first instruction (e.g., the air purifying instruction), the master 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.

In step 210, when the main controller 400 receives the second instruction (for example, the air purifying stopping instruction), the main controller 400 controls the first power source 240 and the second power source 320 to stop supplying power to the motor 210 and the transformer 310, respectively. In this way, the emitter electrode segment 100 stops rotating, while the emitter electrode segment 100 stops releasing negative ions.

The foregoing is merely a specific embodiment of the disclosure, but the protection scope of the disclosure is not limited thereto, and any person skilled in the art who is skilled in the art will recognize that changes or substitutions are within the technical scope of the disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
