Background

At present, sterilization, disinfection and air purification are more and more paid more attention by people, and nanometer water ions are more and more paid more attention by people due to the advantages of small particle size, stable performance, weak acidity, sterilization, peculiar smell removal, no consumable material and the like.

The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.

The present embodiment provides an air conditioner that performs a cooling and heating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The cooling and heating cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

The low-temperature and low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas in a high-temperature and high-pressure state, and the compressed refrigerant gas is discharged. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve, and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat exchange with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor, an outdoor heat exchanger, and an outdoor fan, the indoor unit of the air conditioner includes a portion of an indoor heat exchanger and an indoor fan, and a throttling device (e.g., a capillary tube or an electronic expansion valve) may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The air conditioner performs a heating mode when the indoor heat exchanger serves as a condenser, and performs a cooling mode when the indoor heat exchanger serves as an evaporator.

The indoor heat exchanger and the outdoor heat exchanger are switched to be used as a condenser or an evaporator, a four-way valve is generally adopted, and specific reference is made to the arrangement of a conventional air conditioner, which is not described herein again.

The refrigeration working principle of the air conditioner is as follows: the compressor works to enable the interior of the indoor heat exchanger (in the indoor unit, the evaporator at the moment) to be in an ultralow pressure state, liquid refrigerant in the indoor heat exchanger is rapidly evaporated to absorb heat, air blown out by the indoor fan is cooled by the coil pipe of the indoor heat exchanger to become cold air which is blown into a room, the evaporated and vaporized refrigerant is compressed by the compressor, is condensed into liquid in a high-pressure environment in the outdoor heat exchanger (in the outdoor unit, the condenser at the moment) to release heat, and the heat is dissipated into the atmosphere through the outdoor fan, so that the refrigeration effect is achieved by circulation.

The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the indoor heat exchanger (the condenser at this time), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, thereby achieving the purpose of increasing the indoor temperature. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at this time), is evaporated, gasified and absorbs heat to form gas, absorbs heat of outdoor air (the outdoor air becomes cooler), becomes a gaseous refrigerant, and enters the compressor again to start the next cycle.

Because the air conditioner is operated, the indoor is usually closed to reduce energy consumption, the closed time is long, the indoor air quality is difficult to avoid to be influenced, and in order to purify the indoor air, the following embodiment discloses an air purification device.

As shown in fig. 2 to fig. 4, the high voltage power module 300 specifically includes a high voltage package 310 and a power PCB 320, a high voltage line of the high voltage package 310 is connected to the emitter electrode 210 by way of clamping connection of a high voltage electrode 330, and in this embodiment, is specifically connected to the water absorption portion 211, the high voltage electrode 330 is positioned in the space 400 in the housing and is clamped at a position approximately at the height center of the water absorption portion 211, the high voltage package 310 applies negative high voltage to the high voltage electrode 330, and excites water in micropores on the surface of the water absorption portion 211 by high voltage ionization, so as to generate nano water ions with negative electricity; the high voltage pack 310 and the power supply PCB 320 can be an integrated structure, embedded in the space 400 in the shell, connected with a power supply by arranging a wiring groove and supplying high voltage to the transmitting electrode 210; the high-voltage package 310 and the power supply PCB 320 are filled with the pouring sealant, the pouring sealant can protect electrical components such as the high-voltage package 310 and the power supply PCB 320, the electrical components cannot invade even if water or moisture is met in the use process of the air conditioner, the use safety of an electrical appliance is guaranteed, and in addition, the electrical appliance can achieve the shockproof effect after the pouring sealant is used, and the electrical appliance is prevented from falling off.

Because the water absorption part 211 is made of water absorption material, the strength of the water absorption part is limited, so that the structural strength of the emission electrode 210 is limited, and in order to enhance the structural strength of the emission electrode 210, in this embodiment, the emission electrode 210 further comprises a hard supporting part 213, the supporting part 213 is located at the bottom end of the water absorption part 211 and is connected with the water absorption part 211 to fix the water absorption part 211, and the supporting part 213 plays a skeleton role for the water absorption part 211 to prevent the water absorption part 211 from deforming to influence the point discharge effect; in order to prevent the effective water absorption area of the water absorption portion 211 from being affected as much as possible, the supporting portion 213 is selected to be a needle-like structure, as shown in fig. 2 and 9, the bottom end of the water absorption portion 211 is inserted into the water absorption portion 211 to support the water absorption portion 211, which may be made of a hard material such as plastic or metal, and the supporting portion 213 may be integrally formed with the housing 100 or may be a separate component and fixed in the housing 100.
