Description

Air conditioners and air purification devices

[0001] This application claims priority to Chinese Patent Application No. 202411218942.7, filed on August 30, 2024; and Chinese Patent Application No. 202422139449.8, filed on August 30, 2024; Chinese Patent Application No. 202422137063.3, filed on August 30, 2024; and Chinese Patent Application No. 202422217859.X, filed on September 10, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of air purification technology, and in particular to an air conditioner and an air purification device. Background Technology

[0003] As living standards improve, people's demand for indoor odor purification is constantly increasing. Currently, the commonly used odor removal technology is mainly based on adsorption, which has problems such as unsatisfactory adsorption effect and easy saturation of adsorption materials.

[0004] Dual-dielectric low-temperature plasma discharge technology has a good deodorization effect. This technology can directly break down the molecular chains of odor molecules and ultimately oxidize them into carbon dioxide and water under the action of the generated plasma. However, a major problem that currently limits the application of this technology is that a large amount of ozone is inevitably generated during the dielectric barrier discharge process. Summary of the Invention

[0005] This disclosure aims to solve the problem of ozone removal and energy consumption reduction.

[0006] According to some embodiments of this disclosure, an air conditioner is provided, including a casing, a heat exchange duct, an air supply device, and an air purification device; the casing has a return air section and an air outlet section formed thereon; the heat exchange duct is formed between the return air section and the air outlet section for airflow; the air supply device is disposed in the heat exchange duct for driving airflow to circulate within the heat exchange duct; a refrigerant circulation loop is formed by connecting a compressor, a main expansion valve, a condenser, and an evaporator through refrigerant pipelines; the air purification device is disposed in the return air section or the heat exchange duct, and the air purification device includes a plasma generator and an ozone decomposition device; the plasma generator is used to purify the gas flowing through it; the ozone decomposition device is connected to the refrigerant circulation loop, and the ozone decomposition device is configured such that at least the refrigerant diverted to its interior through the refrigerant circulation loop can heat and decompose the ozone generated by the plasma generator.

[0007] The air conditioner disclosed herein uses a plasma generator to purify the airflow. The plasma generator breaks down odor molecules by generating high-voltage discharge, and the plasma reacts with the broken molecules to produce carbon dioxide and water, resulting in a good odor removal effect. At the same time, the air conditioner is equipped with an ozone decomposition device, which is connected to the refrigerant circulation loop of the air conditioner. The refrigerant in the air conditioner flows into the ozone decomposition device to heat it, providing heat for the decomposition of ozone and accelerating the decomposition rate and efficiency. By utilizing the refrigerant inside the air conditioner, there is no need to set up a separate heating element, which reduces energy consumption and manufacturing costs. Attached Figure Description

[0077] The following description, in conjunction with the accompanying drawings, clearly and completely describes some embodiments of this disclosure. Obviously, the described embodiments are merely some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0078] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples," etc., are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0079] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0080] In describing some embodiments, the terms "coupled" and "connected," and their derivative expressions, may be used. The term "connected" should be interpreted broadly; for example, a "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. The term "coupled" indicates that two or more components have direct physical or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that do not have direct contact with each other but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content of this document.

[0081] "At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

[0082] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0083] The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.

[0084] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0085] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0086] The ozone produced is beneficial for odor control and can improve purification efficiency, but excess ozone released into the air is harmful to the human body. Although there are catalysts on the market specifically designed to decompose ozone, their effectiveness is not ideal.

[0087] There are two main methods for removing ozone: one is to use a catalyst to decompose ozone, and the other is to remove ozone by heating it up. When the temperature reaches 60°C, ozone can decompose rapidly. However, heating is usually achieved through electric heating, which is very energy-intensive.

[0088] To address the aforementioned problems, in some embodiments of this disclosure, an air conditioner is proposed, as shown in Figures 1 and 2. The air conditioner may include a housing 100. The housing 100 constitutes the outer casing of the indoor unit of the air conditioner. A heat exchange air duct 130 may be formed inside the housing 100.

[0089] In some embodiments, as shown in FIG1, a return air section 110 may be formed on the housing 100. The return air section 110 may be a return air inlet formed on the housing 100 so that external airflow can enter the interior of the housing 100.

[0090] In some embodiments, as shown in FIG1, an air outlet 120 may be formed on the housing 100. The air outlet 120 may be an air vent formed on the housing 100 for discharging the heat-exchanged airflow.

[0091] In some embodiments, as shown in FIG1, a heat exchange duct 130 may be formed between the return air section 110 and the outlet air section 120. The heat exchange duct 130 can be used to circulate airflow, which enters from the return air section 110, flows through the heat exchange duct 130, and then flows out from the outlet air section 120. The airflow flowing into the heat exchange duct 130 undergoes heat exchange within it.

[0092] In some embodiments, as shown in FIG1, the air conditioner may include an evaporator 240. The evaporator 240 may be arranged within a heat exchange duct 130, and the evaporator 240 may be used to exchange heat with the airflow flowing through the heat exchange duct 130. Through heat exchange between the evaporator 240 and the airflow within the heat exchange duct 130, the airflow can be heated or cooled, thereby ensuring that the airflow blown out from the air outlet 120 is heated or cooled, thus achieving the cooling or heating effect of the air conditioner.

[0093] In some embodiments, as shown in FIG1, the air conditioner may include an air supply device 140. The air supply device 140 may be disposed within the heat exchange duct 130. The air supply device 140 may be used to drive airflow to circulate within the heat exchange duct 130 and control the flow rate of the airflow within the heat exchange duct 130. The air supply device 140 can draw airflow from the return air section 110 into the heat exchange duct 130, exchange heat with the evaporator 240, and then deliver the airflow from the air outlet section 120, thereby providing the power for the airflow circulation.

[0094] In some embodiments, as shown in Figures 3 and 4, the air conditioner may include a refrigeration cycle loop. The refrigeration cycle loop may be formed by connecting a compressor 210, a main expansion valve 230, a condenser 220, and an evaporator 240 via refrigerant piping. The refrigeration cycle of the air conditioner is executed by using the compressor 210, condenser 220, main expansion valve 230, and evaporator 240. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat the indoor space.

[0095] In some embodiments of this disclosure, as shown in Figures 1 and 2, a plasma generator 40 can be installed at a location in the airflow path, such as the return air section 110 or the heat exchange duct 130 of the air conditioner, so that the gas flowing through it can be purified.

[0096] The main function of the low-temperature plasma generator 40 is to break down the molecular chains of odor molecules into small molecular fragments. At the same time, it generates a large amount of highly active plasma during the ionization of air. The plasma reacts further with the molecular fragments to produce harmless substances such as carbon dioxide and water, thereby eliminating the odor.

[0097] The plasma generator 40 removes odors by breaking down the molecular chains of odor molecules using a high-voltage electric field. The plasma method can completely destroy the odor molecular chains, resulting in more thorough and effective odor removal. Compared with the adsorption method of odor removal in related technologies, there is no problem of odor molecules saturating and volatilizing.

[0098] However, during the process of high-voltage ionization of air by the plasma generator 40, a large amount of ozone will also be generated. An appropriate amount of ozone can achieve the effect of eliminating odors and sterilizing, but the large amount of excess ozone generated by the plasma generator 40 and released into the air will be harmful to the human body. Therefore, when the plasma generator 40 is used, it is also necessary to decompose and eliminate the ozone it generates.

[0099] In some embodiments of this disclosure, as shown in FIG2, an ozone decomposition device 70 may be provided in the airflow path of the air conditioner. The ozone decomposition device 70 is mainly used to decompose the ozone generated by the plasma generator 40.

[0100] In some embodiments, as shown in Figures 1 and 2, the plasma generator 40 and the ozone decomposition device 70 can be arranged sequentially along the airflow direction of the air conditioner to ensure that the ozone decomposition device 70 can effectively decompose the ozone generated from the plasma generator 40.

[0101] In some embodiments of this disclosure, as shown in Figures 3 and 4, the ozone decomposition device 70 can be connected to a refrigerant circulation loop. The ozone decomposition device 70 can be configured to heat and decompose the ozone generated by the plasma generator 40 by at least diverting the refrigerant inside it through the refrigerant circulation loop.

[0102] By diverting the refrigerant inside the air conditioner to the ozone decomposition device 70, the ozone generated by the plasma generator 40 is decomposed, eliminating the need for a separate electric heating element and reducing energy consumption.

[0103] The air conditioner has a plasma generator 40 installed in the airflow path. When in use, the electric field discharge of the plasma generator 40 can break down odor molecules, achieving a good odor removal effect.

[0104] Meanwhile, an ozone decomposition device 70 is configured and connected to the refrigeration cycle circuit of the air conditioner. The refrigerant in the refrigeration cycle circuit is diverted to the ozone decomposition device 70. The ozone generated from the plasma generator 40 is heated by the ozone decomposition device 70 to decompose the ozone. There is no need to set up a separate electric heating element for heating, which reduces energy consumption. Energy consumption is reduced while ensuring good odor removal effect.

[0105] In some embodiments, as shown in Figures 1 and 2, the air conditioner may include an air purification device. The air purification device may be located within the return air section 110 or the heat exchange duct 130. The air purification device may include a plasma generator 40 and an ozone decomposition device 70.

[0106] In some embodiments of this disclosure, as shown in Figures 5 and 6, the ozone decomposition device 70 may include an ozone generator 710. An ozone decomposition catalyst 720 may be coated on the ozone generator 710. The ozone decomposition catalyst 720 can be used to catalytically decompose ozone flowing through the ozone generator 710.

[0107] In some embodiments, as shown in Figures 5 and 6, the ozone decomposition catalyst 720 can be coated on the ozone matrix 710, and the ozone matrix 710 can constitute a support for the ozone decomposition catalyst 720. When the gas flow passes through the ozone matrix 710, it passes through the ozone decomposition catalyst 720 coated on it, and the ozone is decomposed and catalyzed by the ozone decomposition catalyst 720.

[0108] In some embodiments of this disclosure, as shown in Figures 7 and 8, the ozone decomposition device 70 may include an ozone heating element 730. The ozone heating element 730 may be mounted on an ozone source 710, and a refrigerant channel 731 connected to a refrigerant pipeline may be formed inside the ozone heating element 730. The refrigerant channel 731 may be configured to heat the ozone by exchanging heat with the ozone flowing through the ozone source 710.

[0109] In some embodiments of this disclosure, both the ozone generator 710 and the ozone heating element 730 may be thermally conductive to facilitate rapid heat transfer.

[0110] In some embodiments of this disclosure, the ozone generator 710 can be a metallic material such as copper or aluminum, or a ceramic material such as alumina or silicon nitride.

[0111] In some embodiments of this disclosure, the ozone heating element 730 may be a component made of thermally conductive materials such as copper or aluminum.

[0112] The ozone generator 710 is thermally conductive. When high-temperature refrigerant flows into the ozone heating element 730 mounted above it, heat is transferred to the ozone generator 710, and then to the ozone decomposition catalyst 720 above it, thereby increasing the activity of the ozone decomposition catalyst 720 and improving the ozone decomposition rate.

[0113] In some embodiments, as shown in FIG8, the refrigerant channel 731 can be connected to the refrigerant circulation loop and can be used to introduce the refrigerant medium in the refrigerant circulation loop into its interior. The ozone flowing through the ozone gas 710 will exchange heat with the refrigerant medium introduced into the refrigerant channel 731, thereby heating the ozone through the refrigerant medium, improving the decomposition rate and efficiency of ozone, and realizing the rapid decomposition of ozone.

[0114] In some embodiments, as shown in Figures 6 and 8, when the ozone decomposition device 70 is configured, an ozone decomposition catalyst 720 can be coated on the ozone matrix 710. A refrigerant channel 731 for guiding air conditioner refrigerant is provided inside the ozone heating element 730. Through the combined heat generation of the ozone decomposition catalyst 720 and the refrigerant medium within the refrigerant channel 731, ozone is decomposed simultaneously, improving ozone decomposition efficiency and speed, resulting in a good ozone decomposition effect.

[0115] In some embodiments of this disclosure, as shown in FIG6, an airflow channel 711 penetrating the ozone matrix 710 may be formed on the ozone matrix 710, and an ozone decomposition catalyst 720 is coated on the inner wall of the airflow channel 711.

[0116] In some embodiments of this disclosure, as shown in Figures 5 and 6, the ozone generator 710 may include a first adsorption frame 712 and a body component 713 assembled within the first adsorption frame 712. An airflow channel 711 may be provided on the body component 713, penetrating the body component 713.

[0117] In some embodiments of this disclosure, as shown in Figures 5 and 6, the ozone generator 710 may include a first adsorption frame 712 and a body component 713 assembled within the first adsorption frame 712. The body component 713 may have a substrate surface 714 located in the airflow path of the ozone generator 710, and an ozone decomposition catalyst 720 is coated on the substrate surface 714.

[0118] In some embodiments of this disclosure, as shown in Figures 7 and 8, the ozone generator 710 may include a second adsorption frame 715 and sub-components 716. Multiple sub-components 716 may be provided. Sub-components 716 may be mounted on the second adsorption frame 715. Multiple sub-components 716 may be parallel to each other and connected. An airflow channel 711 is formed between adjacent sub-components 716. An ozone decomposition catalyst 720 may be coated on the outer wall of the sub-component 716 constituting the airflow channel 711.

[0119] In some embodiments of this disclosure, as shown in FIG8, an ozone decomposition catalyst 720 may be coated on the ozone heating element 730, which can increase the area of ​​the ozone decomposition catalyst 720, increase the contact area with the airflow, and improve the ozone decomposition effect.

[0120] In some embodiments of this disclosure, as shown in Figures 7 and 8, the ozone generator 710 may include a second adsorption frame 715 and sub-components 716. Multiple sub-components 716 may be provided and may be assembled on the second adsorption frame 715. Multiple sub-components 716 are parallel to each other and connected in series by a bent ozone heating element 730.

[0121] In some embodiments of this disclosure, the ozone heating element 730 may also be attached to the outer surface of the ozone matrix 710, which can transfer heat to the ozone decomposition catalyst 720 coated on the ozone matrix 710.

[0122] In some embodiments of this disclosure, the refrigeration cycle loop may include a refrigerant heating line 26. The ozone heater 730 can be connected to the refrigeration cycle loop via the refrigerant heating line 26.

[0123] In some embodiments of this disclosure, as shown in Figures 3 and 4, the refrigerant heating line 26 may include a first line 260. The first line 260 may be connected in parallel on both sides of the evaporator 240, and an ozone decomposition device 70 is provided on the first line 260. The first line 260 may be used to divert refrigerant to the ozone decomposition device 70 when the air conditioner is heating.

[0124] In some embodiments of this disclosure, as shown in Figures 3 and 4, the refrigerant heating line 26 may include a second line 270. One end of the second line 270 may be connected to the first line 260, and the other end of the second line 270 may be connected between the four-way valve 250 and the condenser 220. The second line 270 may be used to divert refrigerant to the ozone decomposition device 70 during air conditioning cooling.

[0125] In some embodiments, as shown in Figures 3 and 4, the refrigeration cycle loop may include an ozone control valve assembly. The ozone control valve assembly may be arranged on the first pipe 260 and the second pipe 270, and the ozone control valve assembly may be configured to control the refrigerant flow path and refrigerant flow rate in the heated refrigerant pipe 26 by switching on and off and by switching the opening degree.

[0126] In some embodiments of this disclosure, as shown in Figures 3 and 4, the ozone control valve assembly may include a first throttling component 281 and a second throttling component 282. The first throttling component 281 may be arranged on the first conduit 260. The second throttling component 282 may be arranged on the second conduit 270.

[0127] In some embodiments of this disclosure, the first throttling component 281 is a first electronic expansion valve, and the second throttling component 282 is a second electronic expansion valve.

[0128] In some embodiments, when the air conditioner is cooling or heating, the connection or disconnection of the first pipe 260 and the second pipe 270 with the ozone decomposition device 70 can be controlled by switching the opening and closing of the first throttling component 281 and the second throttling component 282, so as to ensure that the refrigerant enters the ozone decomposition device 70.

[0129] In some embodiments, the temperature of the refrigerant flowing into the ozone decomposition device 70 can be controlled by controlling the opening degree of the first throttling component 281 or the second throttling component 282, thereby controlling the ozone decomposition rate.

[0130] In some embodiments, when the opening degree of the first throttling component 281 or the second throttling component 282 is reduced, the refrigerant temperature can be lowered; when the opening degree of the first throttling component 281 or the second throttling component 282 is increased, the refrigerant temperature can be raised.

[0131] In some embodiments, during the cooling operation of the air conditioner, as shown in Figure 3, the first throttling component 281 is closed. Under the action of the compressor 210, the low-pressure, low-temperature gaseous refrigerant is compressed into a high-temperature, high-pressure gaseous refrigerant. Part of the high-temperature, high-pressure refrigerant from the compressor 210 enters the condenser 220, where it is cooled by the outdoor unit fan. The other part enters the second pipe 270, and the refrigerant flow rate is adjusted by the second throttling component 282. As the opening increases, the flow rate increases, and the refrigerant then flows into the first pipe 260 and into the ozone decomposition device 70, where it releases heat. At this time, the temperature of the ozone decomposition device 70 rises, and the refrigerant, after heat exchange, flows out, mixing with the refrigerant from the condenser 220. It then passes through the main expansion valve 230, becoming a low-temperature, low-pressure state, and enters the evaporator 240 to absorb heat, thereby lowering the indoor temperature and achieving the cooling effect.

[0132] In some embodiments, during air conditioning heating operation, as shown in Figure 4, the second throttling component 282 is closed. Under the action of the compressor 210, the low-pressure, low-temperature gaseous refrigerant is compressed into a high-temperature, high-pressure gaseous refrigerant. Then, after passing through the four-way valve 250 to change the flow direction, part of it enters the evaporator 240 to dissipate heat to the room, and the other part enters the ozone decomposition device 70 through the first throttling component 281. At this time, the first throttling component 281 is opened, and the refrigerant flow rate is adjusted by controlling its opening degree. After the high-temperature refrigerant flows through the ozone decomposition device 70, its temperature rises. After the refrigerant flows out, it mixes with the refrigerant coming out of the evaporator 240 and returns to the outdoor unit condenser 220 to absorb heat.

[0133] In some embodiments, as shown in FIG3, during cooling, the ozone decomposition device 70 can be connected in parallel with the condenser 220 to heat the ozone using the high-temperature refrigerant flowing out of the compressor 210.

[0134] In some embodiments, as shown in FIG4, when heating, the ozone decomposition device 70 can be connected in parallel with the evaporator 240 to heat the ozone using the high-temperature refrigerant flowing out of the compressor 210. This enables the use of the air conditioner refrigerant to heat the ozone whether cooling or heating, thus ensuring the ozone removal effect.

[0135] In some embodiments of this disclosure, as shown in Figures 1 and 2, the air conditioner includes an adsorption device 80. The adsorption device 80 may be arranged between the plasma generator 40 and the ozone decomposition device 70.

[0136] The main function of the low-temperature plasma generator 40 is to break down odor molecular chains into small molecular fragments. At the same time, a large amount of highly active plasma is generated during the ionization of air. The plasma can further react with the small molecular fragments, but this reaction requires a certain reaction time.

[0137] The adsorption device 80 is arranged behind the plasma generator 40. It can adsorb the broken molecular fragments onto its surface, providing a buffer and reaction bed for further plasma reactions, enabling them to undergo fractional reactions.

[0138] Meanwhile, the adsorption device 80 can also re-adsorb the odor molecules that escaped from the plasma generator 40 and were not broken down, thereby improving the purification efficiency.

[0139] By combining the adsorption device 80 and the plasma generator 40, the removal effect of odor analysis is improved.

[0140] The adsorption device 80 is positioned opposite the plasma generator 40. The plasma generated by the plasma generator 40 can also oxidize and decompose the substances adsorbed by the adsorption device 80, thereby regenerating the adsorption and purification module.

[0141] The ozone generated by the plasma generator 40 can also decompose pollutants on the adsorption device 80, and at the same time play a role in sterilization and disinfection, preventing the growth of bacteria in the adsorption device 80. The adsorption device 80 consumes a portion of the ozone, reducing the amount of ozone emitted.

[0142] Excess ozone after being used by the adsorption device 80 will further enter the ozone decomposition device 70 located behind the adsorption device 80, where the ozone will be decomposed.

[0143] The ozone generated by the plasma generator 40 is gradually removed by the adsorption device 80 and the ozone decomposition device 70 working together, ensuring the decomposition and removal effect of ozone.

[0144] In some embodiments of this disclosure, as shown in FIG11, the adsorption device 80 may include an adsorption component 81. An adsorption coating 811 may be coated on the adsorption component 81. The adsorption coating 811 is used to purify the airflow passing through it.

[0145] In some embodiments of this disclosure, the adsorption coating 811 may be an adsorption coating 811 composed of porous adsorption materials such as activated carbon, molecular sieve or graphene, with micropores on the surface, through which the airflow passing through it can be adsorbed and purified.

[0146] In some embodiments, as shown in FIG11, the adsorption device 80 may include a temperature control component 82. The temperature control component 82 may be mounted on the adsorption component 81 and may be connected to a refrigerant circulation loop. The temperature control component 82 may be able to exchange heat between the refrigerant diverted to its interior through the refrigerant circulation loop and the adsorption coating 811.

[0147] The temperature regulating component 82 is connected to the refrigeration cycle loop, enabling it to divert part of the refrigerant in the refrigeration cycle loop. The refrigerant flowing in the refrigeration cycle loop flows into the heat exchange channel inside the component 82 to exchange heat with the adsorption coating 811 on the adsorption component 81, thereby regulating the temperature of the adsorbed substance in the adsorption coating 811.

[0148] In some embodiments, as shown in FIG11, when the temperature of the refrigerant flowing into the temperature regulating component 82 is low, the low-temperature refrigerant exchanges heat with the adsorption component 81 and the adsorption coating 811, thereby reducing the temperature of the adsorption component 81 and the adsorption coating 811 above it, which in turn reduces the temperature of the adsorbed substance in the adsorption coating 811, improves the adsorption performance, makes the adsorption more complete, and improves the adsorption efficiency and adsorption capacity.

[0149] When adsorption is saturated, a high-temperature refrigerant can be introduced into the temperature control component 82. The high-temperature refrigerant will exchange heat with the adsorption component 81 and the adsorption coating 811, causing the temperature of the adsorption coating 811 to rise. After the adsorption coating 811 rises to a certain temperature, desorption and regeneration can be achieved.

[0150] The material of the adsorption component 81 can be a thermally conductive material to improve the heat exchange effect.

[0151] The adsorption component 81 can be made of metal materials such as copper and aluminum, or ceramic materials such as alumina and silicon nitride.

[0152] The structure of the adsorption component 81 can be the same as that of the ozone generator 710, and the structure of the temperature regulating component 82 can be the same as that of the ozone heating element 730. The connection and cooperation between the adsorption component 81 and the temperature regulating component 82 can be the same as the connection and cooperation between the ozone heating element 730 and the ozone generator 710, which will not be described in detail here.

[0153] In some embodiments of this disclosure, as shown in Figures 9 and 10, the refrigerant circulation loop may include a temperature-regulating refrigerant line 290. The temperature-regulating refrigerant line 290 may be arranged in parallel on both sides of the evaporator 240. A temperature-regulating component 82 is connected to the temperature-regulating refrigerant line 290, which can be used to introduce refrigerant from the refrigerant circulation loop into the temperature-regulating component 82.

[0154] In some embodiments, as shown in Figures 9 and 10, the temperature control valve 291 can be connected to the temperature-controlled refrigerant line 290. The temperature of the refrigerant flowing through the temperature-controlled component 82 is controlled by switching the opening degree of the temperature control valve 291; when the opening degree is smaller, the refrigerant temperature decreases, and when the opening degree is larger, the refrigerant temperature increases.

[0155] In some embodiments of this disclosure, the temperature control valve 291 may be a third throttling component. The temperature control valve 291 may be connected to the side near the condenser 220. The third throttling component may be a third electronic expansion valve.

[0156] In some embodiments, as shown in FIG9, when the air conditioner is running in cooling mode, the first throttling component 281 is closed, the main expansion valve 230 and the third throttling component are opened, and the refrigerant is compressed by the compressor 210 into a high-temperature and high-pressure gaseous refrigerant under the action of the compressor 210.

[0157] Part of the high-temperature, high-pressure refrigerant from compressor 210 enters condenser 220, while the other part enters second pipe 270 and first pipe 260 before entering ozone decomposition device 70. The refrigerant releases heat upon entering ozone decomposition device 70, causing its temperature to rise. After heat exchange, the refrigerant flows out. Part of the refrigerant flowing out from condenser 220 and ozone decomposition device 70 enters evaporator 240 to absorb heat, while part enters adsorption device 80 to absorb heat, thus lowering the indoor temperature and achieving a cooling effect. The refrigerant also absorbs heat in adsorption device 80, lowering its temperature and improving its adsorption performance.

[0158] By connecting the adsorption device 80 to the refrigerant circulation loop of the air conditioner, the adsorption capacity can be improved by cooling the refrigerant flowing into its interior.

[0159] In some embodiments of this disclosure, as shown in Figures 1 and 12, the plasma generating apparatus 40 may consist of a grounding portion 400, a power supply portion 500, and an emission electrode assembly laterally connected between the grounding portion 400 and the power supply portion 500.

[0160] In some embodiments of this disclosure, as shown in Figures 1 and 12, the grounding portion 400 is connected to the ground to perform a grounding function. The power supply portion 500 can be used to supply power to the transmitting electrode assembly electrically connected thereto.

[0161] In some embodiments of this disclosure, as shown in FIG12, the transmitting electrode assembly may include a plurality of electrode components 600, which may be arranged side by side.

[0162] During connection, one end of some of the multiple electrode components 600 can be electrically connected to the power supply unit 500, and the other end of the electrode component 600 can be mechanically connected to the grounding unit 400. The two ends of the electrode component 600 are supported and fixed by the power supply unit 500 and the grounding unit 400, respectively.

[0163] Another part of the multiple electrode components 600 can be grounded to the grounding part 400. The other end of the electrode component 600 can be mechanically assembled to the power supply part 500. The two ends of the electrode component 600 are supported and fixed by the power supply part 500 and the grounding part 400, respectively.

[0164] After the connection is completed, among the adjacent electrode components 600, one electrode component 600 is electrically connected to the power supply unit 500 at one end and is mounted to the grounding unit 400 at the other end. The other electrode component 600 is connected to the grounding unit 400 at one end for grounding and is mounted to the power supply unit 500 at the other end.

[0165] The electrode component 600 electrically connected to the power supply unit 500 can form a high-voltage electrode component 600. The electrode component 600 groundedly connected to the grounding unit 400 can form a grounded electrode component 600.

[0166] The high-voltage electrode component 600 is connected to the power supply unit 500, and the grounding electrode component 600 is connected to the grounding unit 400. The high-voltage electrode component 600 and the grounding electrode component 600 correspond to different voltages. Therefore, a potential difference can be created between adjacent high-voltage electrode components 600 and grounding electrode components 600, forming a high-frequency, high-voltage electric field. This high-frequency, high-voltage electric field can break down the molecular chains of odor molecules into small molecular fragments.

[0167] In some embodiments of this disclosure, as shown in Figures 13 and 14, a discharge gap 601 may be formed between two adjacent electrode components 600. The distance of the discharge gap 601 between the two electrode components 600 can be 2 to 5 mm.

[0168] The grounding part 400 and the power supply part 500 are respectively arranged at both ends of the transmitting electrode assembly. During connection, one end of a portion of the electrode component 600 is electrically connected to the power supply part 500, and the other end is mounted to the grounding part 400. Alternatively, one end of the portion of the electrode component 600 is electrically connected to the grounding part 400 for grounding, and the other end is mounted to the power supply part 500.

[0169] The above connection method not only supports and fixes the electrode component 600, but also integrates multiple electrode components 600 with the grounding part 400 and the power supply part 500. The entire connection structure is not only compact but also simpler, making it easier to assemble into the return air part 110 or the air outlet part 120 of the air conditioner during use, which facilitates assembly and installation.

[0170] In some embodiments, as shown in Figures 16, 17 and 18, the electrode component 600 may include an insulating dielectric shell 610 and internal conductive components.

[0171] In some embodiments of this disclosure, the insulating dielectric shell 610 may be a tubular component, and the material of the insulating dielectric shell 610 may be quartz glass, ceramic, PTFE or nylon.

[0172] In some embodiments of this disclosure, as shown in Figures 14 and 16, the insulating dielectric shell 610 may be provided with a limiting protrusion 612 and a threaded connection 611 at both ends for connection with the grounding part 400 or the power supply part 500.

[0173] In some embodiments of this disclosure, as shown in Figures 16 and 17, the conductive component may include a conductive element 620. The conductive element 620 is hollow. A notch 621 extending axially may be formed on the sidewall of the conductive element 620. The notch 621 may be configured to radially deform the conductive element 620 fitted into the insulating dielectric shell 610, so as to fit snugly against the inner wall of the insulating dielectric shell 610.

[0174] During processing, wire cutting technology is used to extend the conductive component 620 axially to create a notch 621. This allows the conductive component 620 to undergo elastic deformation in the radial direction under internal stress, increasing its diameter. At this point, the conductive component 620 with the notch exhibits a certain elastic deformation in the diameter direction.

[0175] When the actual inner diameter of the insulating dielectric shell 610 is larger than the reference inner diameter due to processing deviation, the conductive component 620 will expand radially to ensure that the outer wall of the conductive component 620 matches the inner diameter of the insulating dielectric shell 610 and remains in contact with the inner wall of the insulating dielectric shell 610.

[0176] Conversely, if the actual inner diameter of the insulating dielectric shell 610 is smaller than the reference inner diameter due to processing deviation, the conductive component 620 inserted inside it will be compressed radially and deformed due to the squeezing force of the inner wall of the insulating dielectric shell 610, thus reducing its size. This ensures a tight fit with the inner wall of the insulating dielectric shell 610, thereby guaranteeing the parallelism and installation accuracy of the plasma electrode.

[0177] In some embodiments of this disclosure, the conductive element 620 is a metal element that is conductive and can be used to ensure that the electrode component 600 conducts electricity normally.

[0178] In some embodiments of this disclosure, the outer diameter of the conductive element 620 is 5% to 8% smaller than the inner diameter of the insulating dielectric shell 610, and the wall thickness is <0.7mm, so that the deformation in the diameter direction after processing can meet the processing error requirements of the insulating dielectric shell 610.

[0179] When in use, the conductive component 620 should not expand too much, which would prevent it from being effectively inserted into the insulating dielectric shell 610, nor should it expand too little, which would cause the conductive component 620 to wobble inside the insulating dielectric shell 610. The diameter of the conductive component 620 should be set such that its inner diameter is 5% to 8% smaller than the outer diameter of the insulating dielectric shell 610 to ensure that the conductive component 620 deforms within a suitable size range.

[0180] In some embodiments of this disclosure, as shown in Figures 16, 17, and 18, the conductive component may include a conductive connector 630. The conductive connector 630 may be disposed within an insulating dielectric housing 610. One end of the electrical connector 333 may be connected to the conductive component 620. One end of the electrical connector 333 may extend from the insulating dielectric housing 610. An external thread 631 is provided on the extended end of the electrical connector 333.

[0181] In some embodiments of this disclosure, the conductive connector 630 may be a conductive post, and the conductive connector 630 may be welded and fixed to the conductive component 620.

[0182] In some embodiments of this disclosure, as shown in FIG16, a sealing element 650 may be provided at the connection position between conductive connector 630 and conductive element 620. The sealing element 650 may be a sealing rubber plug. The insulating medium shell 610 area where conductive connector 630 is located is filled with potting resin.

[0183] In some embodiments of this disclosure, as shown in FIG16, a raised positioning protrusion 613 may be formed on the inner wall of the insulating dielectric shell 610. The positioning protrusion 613 can be used within the insertion notch 621 to guide and position the installation of the conductive element 620.

[0184] By setting the positioning protrusion 613, the notch 621 can be oriented in one direction after all conductive parts 620 are installed in place, reducing the impact on the discharge effect of electrode parts 600.

[0185] In some embodiments of this disclosure, as shown in Figures 14 and 15, the power supply unit 500 may include an insulating power supply housing 510 and a high-voltage power supply unit 520 and an electrical connection assembly assembled within the insulating power supply housing 510.

[0186] In some embodiments of this disclosure, as shown in Figures 14 and 15, a first flange portion 512 may be provided on the insulating power supply housing 510. A first mounting hole may be provided on the first flange portion 512, which can be used to assemble the plasma generator 40 onto an air conditioner.

[0187] In some embodiments of this disclosure, as shown in Figures 14 and 15, a first insertion hole 514 may be formed on the insulating power housing 510. The first insertion hole 514 can be used to insert one end of the high-voltage electrode component 600 that has a limiting protrusion 612, so that the high-voltage electrode component 600 can be quickly inserted into place and its end can be supported.

[0188] In some embodiments of this disclosure, as shown in Figures 14 and 15, a first threaded connection hole 515 may be formed on the insulating power supply housing 510. The first threaded connection hole 515 is used to cooperate with the threaded connection portion 611 on the grounding electrode component 600. The grounding electrode component 600 is screwed into the first threaded connection hole 515 through the threaded connection portion 611 to achieve connection and fixation with the insulating power supply housing 510, and the insulating power supply housing 510 provides support for one end of it.

[0189] In some embodiments of this disclosure, as shown in Figures 13 and 14, the high-voltage power supply unit 520 may include a high-voltage transformer 521 and a PCB board 522 electrically connected to the high-voltage transformer 521. The PCB board 522 is connected to a power line 501, which is connected to an external power source.

[0190] In some embodiments of this disclosure, an electrical connection assembly can connect the electrode component 600 and the high-voltage power supply unit 520, and the electrical connection assembly can be used to transmit power from the high-voltage power supply unit 520 to the electrode component 600.

[0191] In some embodiments of this disclosure, as shown in FIG14, the electrical connection assembly includes a first connector 531. The first connector 531 is conductive, and a plurality of first insertion portions and electrical connection portions 5312 are formed on the first connector 531. The first insertion portions may be first insertion holes, and the first insertion portions may be used to insert conductive connectors 630 corresponding to a plurality of electrode components 600.

[0192] The electrical connection part 5312 can be used for electrical connection with the high-voltage power supply unit 520, and the electrical connection part 5312 can be used for connection with the high-voltage transformer 521 via a wire. The electrical connection part 5312 can be an electrical connector lug.

[0193] In some embodiments of this disclosure, as shown in FIG14, the electrical connection assembly may include a second connector 532. The second connector 532 may be screwed onto the conductive connector 630 and fit against the first connector 531, pressing and fixing the conductive connector 630 to the end face of the insulating dielectric shell 610.

[0194] In some embodiments of this disclosure, as shown in FIG14, the second connector 532 may include a plastic housing 5321. An insertion channel may be formed inside the plastic housing 5321, extending from one end to the other along the axial direction of the plastic housing 5321. The placement of the second connector 532 within the plastic housing 5321 primarily facilitates twisting operations by the operator without the risk of electric shock.

[0195] In some embodiments of this disclosure, as shown in FIG14, the second connector 532 may include a conductive kit 5322. The conductive kit 5322 may be fitted into the insertion channel.

[0196] The contour of the conductive kit 5322 can be adapted to the insertion channel so that it can be inserted into the insertion channel to achieve the corresponding power transmission and conduction functions.

[0197] In some embodiments of this disclosure, as shown in Figures 14 and 18, an internal thread may be formed on the conductive fitting 5322. This internal thread can be used to lock into the external thread 631 on the conductive connector 630.

[0198] In some embodiments of this disclosure, as shown in Figures 13 and 14, a conductive flange 5323 may be formed on the conductive kit 5322. The conductive flange 5323 may be formed around the end of the conductive kit 5322. The conductive flange 5323 may be disposed in contact with the end face of the plastic shell 5321. The conductive flange 5323 may be used to conduct electricity in contact with the first connector 531.

[0199] The second connector 532 is pressed against the first connector 531 and locked in place with the conductive connector 630. The first connector 531 is connected to the high-voltage transformer 521. The electricity transmitted from the high-voltage transformer 521 is transmitted to the first connector 531. The first connector 531 and the second connector 532 are pressed together, and the electricity is transmitted to the second connector 532. The second connector 532 is threadedly connected to the conductive connector 630, and the electricity is finally transmitted to the conductive connector 630.

[0200] In some embodiments of this disclosure, as shown in Figures 12 and 13, the grounding portion 400 may include an insulating grounding housing 410 and a grounding connection assembly 420 assembled within the insulating grounding housing 410, the grounding connection assembly 420 being connected to the grounding wire 401.

[0201] In some embodiments of this disclosure, as shown in Figures 12 and 13, a second flange portion 412 may be extended from the insulating grounding shell. A second mounting hole may be provided on the second flange portion 412, through which the plasma generator 40 and the air conditioner can be assembled and connected.

[0202] The structure of the grounding connection component 420 is the same as that of the electrical connection component. The connection method between the grounding connection component 420 and the electrode component 600 is the same as that between the electrical connection component and the electrode component 600, and will not be described in detail here.

[0203] In some embodiments of this disclosure, as shown in FIG19, the air conditioner may include a first odor concentration sensor, which is arranged at the return air section 110 and is used to detect the odor concentration at the air outlet section 120.

[0204] In some embodiments of this disclosure, as shown in FIG19, the air conditioner may include an ozone concentration sensor arranged at the return air section 110, which is used to detect the concentration of ozone.

[0205] In some embodiments of this disclosure, as shown in FIG19, the air conditioner may include a temperature sensing element arranged on the ozone decomposition device 70, the temperature sensing element being used to detect the temperature of the ozone decomposition device 70.

[0206] In some embodiments of this disclosure, as shown in FIG19, the air conditioner may include a controller that communicates with the first odor concentration sensor, ozone concentration sensor and temperature detection element.

[0207] The controller communicates with the first odor concentration sensor, the ozone concentration sensor, and the temperature detection element to detect and acquire the first odor concentration value, the ozone concentration value, and the temperature value of the ozone decomposition device 70 in real time.

[0208] After the air conditioner is turned on, the system automatically detects the first odor concentration value, ozone concentration, and temperature of the ozone decomposition device 70 at the air outlet 120, and transmits the above detection values ​​to the controller in real time.

[0209] In the initial stage of startup, the first throttling component 281, the second throttling component 282 and the plasma generator 40 are all turned off, and the adsorption device 80 is turned on. Adsorption and purification are carried out through the adsorption device 80. When the odor concentration is low, there is no need to turn on the plasma generator 40. If the plasma generator 40 is not turned on, no ozone is generated, so the ozone decomposition device 70 also does not need to be turned on.

[0210] When the controller detects that the concentration of the first odor is less than the first preset value, it determines that the concentration of the odor after purification is low and meets the usage requirements, and can control the adsorption device 80 to maintain this state of operation.

[0211] As the air conditioner runs for a long time, pollutants accumulate on the adsorption device 80, causing the concentration of the first odor to gradually increase.

[0212] During operation, the controller acquires the first odor concentration value in real time and controls the opening and closing of the plasma generator 40 according to the magnitude of the first odor concentration.

[0213] When the air conditioner detects that the concentration of the first odor is greater than the first preset value but less than the second preset value, it determines that the purification capacity of the adsorption device 80 is starting to weaken, and starts to control the low-temperature plasma generator 40 to ionize and break down the odor molecules.

[0214] When the detected first odor concentration value is less than the first preset value, the adsorption device 80 can be controlled to continue operating.

[0215] After the plasma generator 40 is turned on, the controller acquires the first odor concentration value, the temperature of the ozone decomposition device 70, and the ozone concentration value. When the first odor concentration is between the first preset value and the second preset value, the temperature of the ozone decomposition device 70 is lower than the preset temperature, and the ozone concentration is lower than the first ozone concentration, the controller adjusts the power of the plasma generator 40 according to the magnitude of the first odor concentration.

[0216] After the plasma generator 40 is turned on, ozone will be generated. It is necessary to monitor the ozone concentration and the temperature of the ozone decomposition device 70 in real time to avoid the ozone concentration exceeding the limit and causing harm to the human body.

[0217] Therefore, when making adjustments, if it is determined that the ozone concentration has not reached the first ozone concentration value, the power of the plasma generator 40 can be increased according to the magnitude of the first odor concentration, as shown in Figure 19.

[0218] When adjusting the power of the plasma generator 40 according to the concentration of the first odor, the following control is executed cyclically until the concentration of the first odor is less than the first preset value or the power of the plasma generator 40 is increased to the preset power.

[0219] The control steps for cyclic execution are as follows:

[0220] After a preset time has elapsed, the first odor concentration is obtained. When the first odor concentration is between a first preset value and a second preset value, the power of the plasma generator 40 is increased.

[0221] In the initial operating state, the plasma generator 40 is turned on and operates at the first power.

[0222] After a preset time, such as 5-10 minutes, the concentration of the first odor is detected, and if the concentration of the first odor is less than the first preset value, the plasma generator 40 is controlled to continue operating at the first power.

[0223] When the first odor concentration is detected to be between the first preset value and the second preset value, the power of the plasma generator 40 is increased to the second power, which is greater than the first power. This operation is repeated until the first odor concentration is less than the first preset value and meets the odor concentration requirement, or the power of the plasma generator 40 is increased to the maximum operating power, i.e., the preset power.

[0224] In some embodiments of this disclosure, as shown in FIG19, the controller can be configured to: when the odor concentration is between a first preset value and a second preset value, the temperature of the ozone decomposition device 70 is less than a preset temperature, and the ozone concentration is greater than or equal to the first ozone concentration, adjust the temperature of the ozone decomposition device 70 according to the ozone concentration.

[0225] Before the ozone decomposition device 70 reaches its maximum temperature (i.e., the preset temperature), the ozone concentration can be reduced by controlling the temperature of the ozone decomposition device 70 to accelerate ozone decomposition.

[0226] The controller controls the ozone decomposition device 70 to cyclically perform the following controls to reduce ozone concentration:

[0227] Ozone concentration values ​​are acquired at preset intervals. When the detected ozone concentration is greater than or equal to the first ozone concentration, the ozone decomposition device 70 is heated until the ozone concentration is less than the first ozone concentration or the ozone decomposition device 70 is heated to the preset temperature.

[0228] The preset time can be 5-10 minutes. The preset time is mainly to ensure that the ozone decomposition device 70 has been running stably for a period of time after the last temperature adjustment, in order to check whether the ozone decomposition device 70 at this temperature can reduce the ozone concentration to below the first ozone concentration.

[0229] During control, the ozone decomposition device 70 is heated to different temperatures by opening the first throttling component 281 or the second throttling component 282.

[0230] In the initial state, adjust the opening of the first throttling component 281 or the second throttling component 282 to raise the temperature of the ozone decomposition device 70 to the first temperature. After running for a preset time, detect the ozone concentration again. If the ozone concentration is less than the first ozone concentration, then operate in this state.

[0231] If the ozone concentration is greater than or equal to the first ozone concentration, the opening of the first throttling component 281 or the second throttling component 282 is controlled to raise the temperature of the ozone decomposition device 70 to the second temperature, which is greater than the first temperature.

[0232] This cycle continues until the ozone concentration is less than the first ozone concentration, meeting the ozone concentration requirement, or until the temperature of the ozone decomposition device 70 rises to the preset temperature, i.e., the maximum temperature, and can no longer be increased.

[0233] In some embodiments of this disclosure, as shown in FIG19, the controller may be configured to: when the ozone module temperature reaches a preset temperature and the ozone concentration is greater than or equal to a first ozone concentration, adjust the power of the plasma generator 40 according to the ozone concentration.

[0234] Specifically, when the temperature of the ozone decomposition device 70 reaches the preset temperature and the ozone concentration is greater than or equal to the first ozone concentration, the power of the plasma generator 40 is reduced until the ozone concentration is less than the first ozone concentration.

[0235] If the ozone concentration is higher than the first ozone concentration, it means that the ozone release is excessive and will cause harm to the human body. At this time, it is necessary to ensure that the ozone concentration does not exceed the standard before controlling the odor concentration. Therefore, it is necessary to control and continuously reduce the power of the plasma generator 40 to reduce the ozone release concentration.

[0236] In some embodiments of this disclosure, as shown in FIG19, the control unit may be configured as follows:

[0237] When the concentration of the first odor is detected to be greater than the second preset value and the ozone concentration is less than the first ozone concentration, the plasma generator 40 is controlled to operate at a preset power and the ozone decomposition device 70 is controlled to operate at a preset temperature.

[0238] If the ozone concentration is less than the first ozone concentration, it means that the ozone concentration has not exceeded the limit. When the first odor concentration is large, the plasma generator 40 can be controlled to operate at the maximum power, i.e., the preset power, and the ozone decomposition device 70 can operate at the highest temperature.

[0239] When the concentration of the first odor is detected to be greater than the second preset value and the ozone concentration is greater than or equal to the first ozone concentration, the ozone decomposition device 70 is controlled to operate at a preset temperature, and the plasma generator 40 is controlled to reduce its power until the ozone concentration is less than the second ozone concentration.

[0240] When the ozone concentration is greater than or equal to the first ozone concentration, it means that the ozone concentration has reached or exceeded the limit. At this time, the ozone decomposition device 70 can be controlled to operate at the highest preset temperature to accelerate ozone decomposition. At the same time, the power of the plasma generator 40 can be continuously reduced from the preset power to reduce the ozone release. The ozone decomposition device 70 accelerates decomposition at high temperature and the reduction of ozone release by reducing the power of the plasma generator 40 can be combined to achieve the effect of rapidly reducing the ozone concentration.

[0241] In some embodiments of this disclosure, the air conditioner may include a second odor concentration sensor, which is arranged at the return air section 110 and is used to detect the second odor concentration at the return air section 110.

[0242] When the difference between the concentration of the second odor and the concentration of the first odor is detected to be greater than the set value, the adsorption device 80 is controlled to maintain its original operation.

[0243] If the difference in odor concentration between the return air section 110 and the outlet air section 120 is greater than the set value, it indicates that the purification performance is good under the current condition. The main reason for the high outlet concentration is that the odor concentration at the inlet is too high, exceeding the purification capacity of the adsorption device. Under this condition, the system will maintain the current operating state and continue to operate.

[0244] If the difference between the concentration of the second odor and the concentration of the first odor is less than the set value, a saturation desorption prompt will be issued to the user.

[0245] When the difference in odor concentration between the two is less than the set value, it is determined that the adsorption capacity of the current adsorption device 80 has been saturated. The adsorption saturation reminder can be issued to the user, and a prompt can be sent to the user to replace the adsorption device 80. If the user does not agree, the current operating state will be maintained, and a reminder will be sent the next time the device is turned on.

[0246] In some embodiments of this disclosure, if the first odor concentration is still greater than the second preset value after the plasma generator 40 has reached the preset power and the ozone decomposition device 70 has reached the preset temperature, and after running for a period of time, the temperature of the adsorption device 80 is controlled to be reduced to improve its adsorption capacity, thereby reducing the first odor concentration value.

[0247] The controller controls the cooling of the adsorption device 80 mainly by controlling the opening of the temperature control valve 291.

[0248] The opening of the temperature control valve 291 is reduced to lower the temperature of the refrigerant flowing into the adsorption device 80, thereby increasing the adsorption performance of the adsorbent material coated on the adsorption component 81 and improving the adsorption effect.

[0249] Air conditioners can not only use ozone decomposition devices and plasma generators together to filter and purify the air, but they can also use plasma generators alone to filter and purify the air, for example, by using a dual-dielectric plasma discharge device.

[0250] As living standards improve, people's demand for indoor odor purification is constantly increasing. Currently, the commonly used odor removal technology is mainly based on adsorption, which has problems such as unsatisfactory adsorption effect and easy saturation of adsorption materials.

[0251] With continuous development, dual-dielectric plasma discharge devices have emerged that use plasma discharge devices to remove odors.

[0252] Dual-dielectric low-temperature plasma discharge technology can directly break down the molecular chains of odor molecules, and under the action of the generated plasma, they are ultimately oxidized into carbon dioxide and water, resulting in a good odor removal effect.

[0253] However, the dual-dielectric low-temperature plasma discharge technology is mainly used in the treatment of industrial organic waste gas. The discharge device has a large power, up to 2kW. The power supply and the dual-dielectric low-temperature plasma generator are set as separate structures. The entire plasma generator has a complex structure and cannot be assembled into an air conditioner.

[0254] To address the aforementioned issues, in some embodiments of this disclosure, an air conditioner is proposed. As shown in FIG20, the air conditioner may include a housing 100, which constitutes the outer shell of the indoor unit of the air conditioner. A heat exchange duct 130 is formed inside the housing 100.

[0255] In some embodiments, as shown in FIG20, a return air section 110 may be formed on the housing 100. The return air section 110 may be an air inlet formed on the housing 100 so that external airflow can enter the interior of the housing 100.

[0256] In some embodiments, as shown in FIG20, an air outlet 120 may be formed on the housing 100. The air outlet 120 may be an air vent formed on the housing 100 and may be used to discharge the heat-exchanged airflow.

[0257] In some embodiments, as shown in FIG20, a heat exchange duct 130 may be formed between the return air section 110 and the return air section 110. The heat exchange duct 130 can be used to circulate airflow, which enters from the return air section 110, flows through the heat exchange duct 130, and then flows out from the return air section 110. The airflow flowing into the heat exchange duct 130 undergoes heat exchange within it.

[0258] In some embodiments, as shown in FIG20, the air conditioner may include an evaporator 240. The evaporator 240 may be arranged within a heat exchange duct. The evaporator 240 may be used to exchange heat with the airflow flowing through the heat exchange duct 130. Through heat exchange between the evaporator 240 and the airflow within the heat exchange duct 130, the airflow can be heated or cooled, thereby ensuring that the airflow blown out from the return air section 110 is heated or cooled, thus achieving the cooling or heating effect of the air conditioner accordingly.

[0259] In some embodiments, as shown in FIG20, the air conditioner may include an air supply device 140. The air supply device 140 may be disposed within the heat exchange duct 130. The air supply device 140 may be used to drive airflow to circulate within the heat exchange duct 130 and control the flow rate of the airflow within the heat exchange duct 130. The air supply device 140 can draw airflow from the return air section into the heat exchange duct 130 to exchange heat with the evaporator, and then deliver the airflow from the return air section 110. The air supply device 140 provides the power for the airflow circulation.

[0260] In some embodiments, the refrigeration cycle loop is formed by connecting a compressor, a main expansion valve, a condenser, and an evaporator 240 via refrigerant piping. The refrigeration cycle of the air conditioner is executed using the compressor, condenser, main expansion valve, and evaporator 240. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat the indoor space.

[0261] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0262] The main expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant that expanded in the main expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0263] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0264] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0265] In some embodiments, an air purification device may be installed in the airflow path of the air conditioner. The air purification device is arranged in the return air section and is used to purify the air exhausted into the room.

[0266] In some embodiments, an air purification device may be arranged at the return air section 110. The air purification device purifies the airflow as it is discharged into the room.

[0267] In some embodiments, the air purification device can be arranged inside the heat exchange duct 130 to purify the airflow passing through the heat exchange duct 130, thus ensuring that the air entering the room is purified clean air.

[0268] In some embodiments, as shown in FIG21, the air purification device may consist of a grounding part 400, a power supply part 500, and a transmitting electrode assembly laterally connected between the grounding part 400 and the power supply part 500.

[0269] In some embodiments, as shown in FIG21, the grounding part 400 can be connected to the ground, and the grounding part 400 can be used to implement the grounding function.

[0270] In some embodiments, as shown in FIG21, the power supply unit 500 can be used to supply power to the transmitting electrode assembly electrically connected thereto.

[0271] In some embodiments, as shown in FIG21, the transmitting electrode assembly may be connected between the grounding portion 400 and the power supply portion 500. The transmitting electrode assembly may include a plurality of electrode components 600, which may be arranged side by side.

[0272] In some embodiments, as shown in Figures 20 and 21, a plurality of electrode components 600 arranged side by side are arranged to extend laterally along the direction from the power supply portion 500 to the ground portion 400.

[0273] In some embodiments, as shown in FIG21, the plurality of electrode components 600 may be parallel to each other and the structures of the plurality of electrode components 600 may be identical.

[0274] In some embodiments, as shown in FIG22, during connection, one end of some electrode components 600 can be electrically connected to the power supply unit 500, and the other end of the electrode component 600 can be mechanically connected to the grounding unit 400. The two ends of the electrode component 600 are supported and fixed by the power supply unit 500 and the grounding unit 400, respectively. Another portion of electrode components 600 can have one end connected to the grounding unit 400 for grounding, and the other end of the electrode component 600 can be mechanically assembled to the power supply unit 500. The two ends of the electrode component 600 are supported and fixed by the power supply unit 500 and the grounding unit 400, respectively.

[0275] In some embodiments, as shown in Figures 21 and 22, a plurality of electrode components 600 electrically connected to the power supply unit 500 and a plurality of electrode components 600 electrically connected to the grounding unit 400 may be arranged alternately in sequence.

[0276] After the connection is completed, one end of one of the adjacent electrode components 600 can be electrically connected to the power supply unit 500, and the other end can be mounted to the grounding unit 400. One end of the other electrode component 600 can be connected to the grounding unit 400 for grounding, and the other end can be mounted to the power supply unit 500.

[0277] In some embodiments, as shown in FIG21, the electrode component 600 electrically connected to the power supply unit 500 forms a high-voltage electrode component 600, and the electrode component 600 connected to the grounding unit 400 forms a grounding electrode component 600.

[0278] The high-voltage electrode component 600 is connected to the power supply unit 500, and the grounding electrode component 600 is connected to the grounding unit 400. The high-voltage electrode component 600 and the grounding electrode component 600 correspond to different voltages. Therefore, a potential difference can be created between adjacent high-voltage electrode components 600 and grounding electrode components 600, forming a high-frequency, high-voltage electric field. This high-frequency, high-voltage electric field can break down the molecular chains of odor molecules into small molecular fragments.

[0279] In some embodiments, as shown in FIG23, a discharge gap 601 for gas molecules to flow through can be formed between two adjacent electrode components 600. The distance of the discharge gap 601 between the two electrode components 600 is 2-5 mm.

[0280] When setting up, the number of electrode components 600 can be set to different numbers according to actual usage requirements. The number of electrode components 600 can be 4, 6 or 8, etc.

[0281] When indoor polluted air passes through the discharge gap 601 formed between the two electrode components 600, the molecular chains of harmful gases are directly broken under the action of the high-frequency high-voltage electric field.

[0282] Meanwhile, plasma is generated during the ionization of air by the electrode component 600. The plasma reacts with the broken small molecules to generate harmless substances such as carbon dioxide and water, thus eliminating odor molecules. At the same time, bacteria and viruses are also killed by the high voltage electric field when passing through the discharge gap 601, which directly destroys their cell walls and RNA, thus achieving a good odor removal and purification effect.

[0283] The airflow entering the air conditioner casing 100 from the return air section will pass through the air purification device arranged in the return air section 110, heat exchange air duct 130 or air outlet 120. When odor molecules in the airflow pass through the discharge gap 601, they will be broken and react with plasma to be eliminated, thus achieving a good odor removal effect on the air conditioner.

[0284] In some embodiments, as shown in FIG21, in terms of structural arrangement, the grounding part 400 and the power supply part 500 are respectively arranged at both ends of the emitting electrode assembly. During connection, one end of a portion of the electrode component 600 is electrically connected to the power supply part 500, and the other end is assembled to the grounding part 400; one end of a portion of the electrode component 600 is connected to the grounding part 400 for grounding, and the other end is assembled to the power supply part 500. This not only achieves the support and fixation of the electrode component 600, but also achieves the integrated connection and assembly of multiple electrode components 600, the grounding part 400, and the power supply part 500. The entire connection structure is not only compact but also simpler, making it easier to assemble into the return air section or return air section 110 of the air conditioner during use, facilitating assembly and installation.

[0285] The electrode component 600 has terminals for electrical connection wiring. During connection, some terminals of the electrode component 600 are connected to the power supply unit 500, and some terminals of the electrode component 600 are connected to the grounding unit 400.

[0286] In some embodiments of this disclosure, as shown in Figures 24, 32 and 33, the electrode component 600 may include an insulating dielectric shell 610 and internal conductive components.

[0287] In some embodiments, the insulating medium shell 610 can be an insulating medium shell with a certain length. In some embodiments, the insulating medium shell 610 is made of a quartz glass tube with good insulation properties.

[0288] In some embodiments, the outer diameter of the insulating dielectric shell 610 is between 10 and 20 mm.

[0289] In some embodiments, the insulating dielectric shell 610 may be made of materials such as ceramic, PTFE or nylon.

[0290] In some embodiments, as shown in Figures 32 and 33, the insulating dielectric shell 610 may have a port 616 through which conductive components are easily assembled into the interior.

[0291] In some embodiments, as shown in Figures 32 and 33, the conductive component may include a conductive element 620. The conductive element 620 may be inserted into the interior of the insulating dielectric housing 610 through the port 616 along the axial direction of the insulating dielectric housing 610. During insertion, the conductive element 620 may be inserted at a position away from the port 616.

[0292] In some embodiments, as shown in Figures 34, 35, and 36, the conductive element 620 is hollow. A notch 621 extending axially may be provided on the sidewall of the conductive element 620. The notch 621 may be configured to radially deform the conductive element 620 assembled inside the insulating dielectric shell 610 so as to fit snugly against the inner wall of the insulating dielectric shell 610.

[0293] The insulating dielectric shell 610 has poor dimensional accuracy during high-temperature manufacturing. Therefore, when the internal dimensions of the insulating dielectric shell 610 are too small, the conductive component 620 will be difficult to insert into the glass tube if the dimensional accuracy of the conductive component 620 remains unchanged.

[0294] Furthermore, because low-temperature plasma electrodes have strict requirements for the parallelism between electrodes, non-parallelism will cause uneven discharge between the electrodes. When the inner wall size of the insulating dielectric shell 610 is too large, the conductive element 620 will wobble inside the insulating dielectric shell 610, causing the conductive element 620 to not be completely attached to the inner wall of the insulating dielectric shell 610, resulting in non-parallelism of the electrodes.

[0295] By providing a notch 621 along the axial direction of the conductive element 620, the notch 621 can communicate with the internal space of the conductive element 620, thereby allowing the conductive element 620 to deform through the notch 621.

[0296] During processing, wire cutting technology is used to extend the conductive component 620 axially to create a notch 621, so that the conductive component 620 will undergo elastic deformation in the radial direction under internal stress, thereby increasing the diameter of the conductive component 620. At this time, the conductive component 620 with the notch has a certain elastic deformation in the diameter direction.

[0297] When the actual inner diameter of the insulating dielectric shell 610 is larger than the reference inner diameter due to processing deviation, the conductive component 620 will expand radially to ensure that the outer wall of the conductive component 620 matches the inner diameter of the insulating dielectric shell 610 and remains in contact with the inner wall of the insulating dielectric shell 610.

[0298] Due to processing deviations, the actual inner diameter of the insulating dielectric shell 610 is smaller than the reference inner diameter. The conductive component 620 inserted inside it is compressed and deformed radially by the squeezing force of the inner wall of the insulating dielectric shell 610, resulting in a smaller size. This ensures a tight fit with the inner wall of the insulating dielectric shell 610, thereby guaranteeing the parallelism and installation accuracy of the plasma electrode.

[0299] In some embodiments, the conductive element 620 may be a metal element, and the conductive element 620 may be conductive. The conductive element 620 may be used to ensure that the electrode conducts normal electricity.

[0300] The conductive component 620 can be made of iron, copper, or stainless steel, ensuring not only conductivity but also a certain degree of rigidity. During assembly, it can be quickly and easily inserted into the insulating dielectric shell 610 for convenient installation.

[0301] In some embodiments, the outer diameter of the conductive element 620 may be 5% to 8% smaller than the inner diameter of the insulating dielectric shell 610, and the wall thickness of the conductive element 620 may be less than 0.7 mm, so that the deformation in the diameter direction after processing can meet the processing error requirements of the insulating dielectric shell 610.

[0302] In some embodiments, the outer diameter of the conductive element 620 may be less than 5%, 6%, or 8% of the inner diameter of the insulating dielectric shell 610. The wall thickness of the conductive element 620 may be 0.1 mm, 0.3 mm, 0.5 mm, or 0.6 mm.

[0303] .

[0304] The conductive component 620 should not expand too much during use, which would prevent it from being effectively inserted into the insulating dielectric shell 610; nor should it expand too little, which would cause the conductive component 620 to wobble inside the insulating dielectric shell 610. The diameter of the conductive component 620 is set such that its inner diameter is 5% to 8% smaller than the outer diameter of the insulating dielectric shell 610 to ensure that the conductive component 620 deforms within a suitable dimensional range.

[0305] In some embodiments, as shown in Figures 33, 35, and 36, the conductive component may include a conductive connector 630. The conductive connector 630 may be disposed within an insulating dielectric shell 610, with one end of the conductive connector 630 connected to a conductive element 620 and the other end of the conductive connector 630 extending out of the insulating dielectric shell 610.

[0306] The conductive connector 630 is mainly used to realize electrical wiring connection. The conductive connector 630 can be used to connect to the power supply part 500 or to the grounding part 400.

[0307] In some embodiments, the conductive connector 630 can be a conductive post, and the conductive connector 630 and the conductive element 620 are arranged side by side in the insulating medium shell 610, extending outward from the port 616.

[0308] In some embodiments, as shown in Figures 33 and 35, an external thread 631 may be provided on the protruding section of the conductive connector 630, which facilitates subsequent wiring operations.

[0309] In some embodiments of this disclosure, as shown in FIG34, the conductive element 620 may have a first end 623 and a second end 624 located at both ends thereto. A notch 621 may extend along the axial direction of the conductive element 620 from the first end 623 to the second end 624.

[0310] In some disclosed embodiments, as shown in FIG34, the notch 621 can be an elongated notch formed along the overall length of the conductive member 620. The elongated opening can be used to ensure that the conductive member 620 can deform radially at various positions along its entire length, ensuring that each position of the conductive member 620 remains in contact with the inner wall of the insulating dielectric shell 610, and ensuring the parallelism and installation accuracy of the electrode component 600.

[0311] In some embodiments, the conductive element 620 can be a conductive sleeve, and the two ends of the conductive element 620 are formed with a first through-hole and a second through-hole, and the notch 621 can extend from the first through-hole to the position of the second through-hole.

[0312] In some embodiments, the two ends of the conductive element 620 may not be continuous. Hollowed-out portions may be formed on the end faces of the two ends of the conductive element 620 at positions corresponding to the notches 621, so as to ensure that the conductive element 620 can undergo normal radial deformation.

[0313] In some embodiments of this disclosure, as shown in FIG34, the conductive element 620 may have a first end 623 and a second end 624 disposed opposite to the first end 623.

[0314] In some embodiments, as shown in FIG38, the notch 621 may include a first deformable opening 6211. The first deformable opening 6211 may extend from the first end 623 of the conductive member 620 along the axial direction of the conductive member 620 toward the second end 624.

[0315] In some embodiments, as shown in FIG38, the notch 621 may include a second deformable opening 6212. The second deformable opening 6212 and the first deformable opening 6211 may be arranged staggered in the circumferential direction of the conductive member 620. The second deformable opening 6212 may extend from the second end 624 of the conductive member 620 toward the first end 623 in the axial direction of the conductive member 620. The end of the second deformable opening 6212 away from the second end 624 may be flush with the end of the first deformable opening 6211 away from the first end 623.

[0316] The first deformation opening 6211 and the second deformation opening 6212, which are arranged in a staggered manner, form a notch 621 arranged along the axial direction of the conductive member 620.

[0317] The first deformation opening 6211 causes the conductive element 620 to deform on the conductive element 620 segment corresponding to the first deformation opening. The second deformation opening causes the conductive element 620 to deform on the conductive element 620 segment corresponding to the second deformation opening 6212. The cooperation of the two ensures that the entire conductive element 620 deforms in the radial direction to fit snugly against the inner wall of the insulating dielectric shell 610.

[0318] In some embodiments of this disclosure, as shown in FIG34, the conductive member 620 may include a sleeve body. A first through portion 625 and a second through portion 626 may be formed at both ends of the sleeve body. The first through portion 625 and the second through portion 626 may communicate with the internal space of the sleeve body. The first through portion 625 is closer to the conductive connector 630 than the second through portion 626.

[0319] In some embodiments of this disclosure, as shown in FIG34, the first through portion 625 can be a first through opening, and the second through portion 626 can be a second through opening. Both are connected to the internal space of the sleeve body to form a conductive kit.

[0320] In some embodiments of this disclosure, as shown in Figures 34 and 37, a connecting portion 627 may be formed around the first through portion 625. The connecting portion 627 may extend axially along the insulating dielectric shell 610 to the conductive connector 630 and connect to it. The first through portion 625 is close to the conductive connector 630, and by forming the connecting portion 627 around the first through portion 625, a connection with the conductive connector 630 can be achieved at a relatively short distance. The connection between the connecting portion 627 and the conductive connector 630 ensures the continuity of the electrical transmission path and guarantees electrical transmission.

[0321] In some embodiments of this disclosure, as shown in Figures 34 and 37, multiple connecting portions 627 may be provided. These multiple connecting portions 627 may be arranged circumferentially along the first through portion 625. The connection between the multiple connecting portions 627 and the conductive connector 630 ensures a robust connection.

[0322] During molding, a portion of the conductive part 620 can be cut off from the middle using wire cutting at one end, leaving a connecting part 627 on each side. The two connecting parts 627 are symmetrically distributed on both sides of the notch 621.

[0323] In some embodiments, as shown in Figures 34 and 35, the connection portion 627 may include an inclined connecting arm 6271. The inclined connecting arm 6271 may be inclined from the conductive member 620 to the conductive connector 630, and the inclined connecting arm 6271 may be used to realize the transition of the connection from the conductive member 620 to the conductive connector 630.

[0324] In some embodiments, as shown in Figures 34 and 35, the connecting portion 627 may include a straight connecting arm 6272, which may be connected to an inclined connecting arm 6271. The straight connecting arm 6272 may conform to the outer wall of the conductive connector 630 and be welded to it. The straight connecting arm 6272 can be welded to the outer wall of the conductive connector 630 to achieve connection with the conductive connector 630.

[0325] During connection, the conductive connector 630 is inserted into the middle position of the multiple connecting parts 627, and the multiple connecting parts 627 can be welded to the conductive connector 630 at the same time by spot welding.

[0326] In some embodiments of this disclosure, a raised positioning protrusion 613 may be formed on the inner wall of the insulating dielectric shell 610. The positioning protrusion 613 may be used within the insertion notch 621 to guide and position the installation of the conductive element 620.

[0327] After the conductive component 620 is machined with a notch 621, there is no conductive material at the notch 621. Therefore, plasma discharge cannot occur at the notch 621. When arranging multiple plasma electrode components 600, the notch 621 cannot be aligned with another plasma electrode component 600; therefore, the notch 621 needs to be positioned.

[0328] By using the positioning protrusion 613 designed at a specific position inside the insulating dielectric shell 610, when installing the conductive component 620, the notch 621 is aligned with the positioning protrusion 613, and the conductive component 620 is inserted into the insulating dielectric. The positioning protrusion 613 guides the notch 621, so that all the notches 621 are inserted into the insulating dielectric shell 610 in the same direction, and the notches 621 of the multiple electrode components 600 all face the same direction.

[0329] In some embodiments of this disclosure, as shown in FIG33, the insulating dielectric shell 610 may have a first connection end 614, and a limiting protrusion 612 may be provided on the insulating dielectric shell 610 near the first connection end 614 for positioning its position when assembled to the power supply part 500 or the grounding part 400.

[0330] During assembly, the insulating dielectric shell 610 is inserted into the power supply section 500 or the grounding section 400. The insertion position of the insulating dielectric shell 610 can be limited by the limiting protrusion 612, so that the insulating dielectric shell 610 can be quickly assembled into place.

[0331] In some embodiments of this disclosure, as shown in FIG33, the insulating dielectric shell 610 may include a second connecting end 615. A threaded connecting portion 611 is formed at the second connecting end 615 to connect and mate with the grounding portion 400 or the power supply portion 500. The threaded connecting portion 611 may be a threaded connecting hole, and the threaded connecting portion 611 is used to be screwed into the power supply portion 500 or the grounding portion 400 for fixation.

[0332] In some embodiments of this disclosure, as shown in FIG33, the insulating dielectric shell 610 may include a fixed sealing assembly. The fixed sealing assembly may include a blocking component 640. The blocking component 640 may be assembled inside the insulating dielectric shell 610, and the blocking component 640 may be located between the second connecting end 615 and the conductive element 620.

[0333] The blocking component 640 can be a plug, mainly serving a sealing function. The plug has a certain length, which increases the creepage distance of the electrode component 600 during use, improving safety. The wall of the insulating dielectric shell 610 and the plug are connected by high-temperature welding. The wall thickness should be between 1 and 1.5 mm.

[0334] During assembly, the conductive component 620 is inserted into the insulating medium shell 610 through the port 616 until the conductive component 620 contacts the bottom plug.

[0335] In some embodiments of this disclosure, as shown in FIG33, the insulating dielectric shell 610 may include a sealing member 650, which may be inserted into the insulating dielectric shell 610. The sealing member 650 may be sleeved at the connection position between the conductive member 620 and the conductive connector 630. The sealing member 650 may be a sealing rubber plug.

[0336] After inserting the conductive component 620 into the bottom of the insulating medium component, the sealing component 650 is pushed into the insulating medium shell 610 using a ring tool until it reaches the welding position of the conductive component 620 and the conductive connector 630. Its main function is to prevent the sealant from the subsequent process from flowing into the interior of the conductive component 620.

[0337] In some embodiments of this disclosure, as shown in FIG33, a sealing filler may be filled inside the insulating medium shell 610, and the sealing filler is filled in the area between the seal 650 and the first connection end 614.

[0338] In some embodiments of this disclosure, the sealing filler can be epoxy resin sealant. The epoxy resin sealant is poured into the remaining space of the insulating medium shell 610 and level with the opening 616. After curing, the assembly of the electrode component 600 is completed.

The PCB board 522 is connected to a power line 501, which is connected to an external power source. After the power line 501 is connected to the external power source, electricity is transmitted to the PCB board 522 and the high-voltage transformer 521.

[0348] In some embodiments of this disclosure, as shown in Figures 25 and 26, the electrical connection component 530 can connect the electrode component 600 and the high-voltage power supply unit 520. The electrical connection component 530 can be used to transmit power from the high-voltage power supply unit 520 to the electrode component 600, which can be a high-voltage electrode component 600.

[0349] The electricity transmitted from the outside to the high voltage transformer 521 will be transmitted to the high voltage electrode component 600 connected to it through the first conductive component, and finally the high frequency and high voltage electricity will be transmitted to the high voltage electrode component 600.

[0350] In some embodiments of this disclosure, as shown in FIG29, the electrical connection assembly 530 may include a first connector 531. The first connector 531 is conductive, ensuring that it can perform the conductive function.

[0351] In some embodiments, as shown in FIG29, the first connector 531 may be a metal part or a first connecting piece.

[0352] In some embodiments, as shown in Figures 26 and 29, a plurality of first insertion portions 5311 may be formed on the first connector 531. The plurality of first insertion portions 5311 are used to insert conductive connectors 630 corresponding to a plurality of electrode components 600.

[0353] In some embodiments, as shown in Figures 26 and 29, the first insertion part 5311 can be a first insertion hole formed on the first connector 531, which is provided through the first connector 531. Multiple first insertion holes can be provided to insert conductive connectors 630 of multiple high-voltage electrode components 600 respectively, so as to realize electrical connection between one and multiple high-voltage electrode components 600.

[0354] In some embodiments, as shown in Figures 26 and 29, an electrical connection portion 5312 may be formed on the first connector 531, which can be used to electrically connect with the high-voltage power supply unit 520.

[0355] In some embodiments, as shown in Figures 26 and 29, the electrical connection portion 5312 may be an electrical connection nose extending from the first connector 531. The electrical connection nose has a connection hole for connecting to the high-voltage transformer 521 via a wire.

[0356] In some embodiments, as shown in Figures 25 and 30, the first conductive component may include a second connector 532. The second connector 532 is screwed onto the conductive connector 630 and fits against the first connector 531, pressing and fixing it to the end face of the insulating dielectric shell 610, forming a first conductive path between the conductive connector 630, the first connector 531, and the second connector 532.

[0357] During assembly, the insulating dielectric shell 610 and the conductive connector 630 extend through the first insertion hole 514 into the assembly space 511, and the second connector 532 is screwed onto the conductive connector 630 located in the assembly space 511.

[0359] The screwing arm continuously screws onto the conductive connector 630 and applies force to the first connector 531, pressing the first connector 531 toward the insulating dielectric shell 610 side, and finally pressing the first connector 531 tightly onto the end face of the insulating dielectric shell 610 to firmly fix the first connector 531.

[0360] In some embodiments, as shown in Figures 25 and 30, the second connector 532 can be pressed against the first connector 531 and locked and fixed with the conductive connector 630. The first connector 531 is connected to the high-voltage transformer 521, and the electricity transmitted from the high-voltage transformer 521 is transmitted to the first connector 531. The first connector 531 and the second connector 532 are pressed together, and the electricity is transmitted to the second connector 532. The second connector 532 is threadedly connected to the conductive connector 630, and finally the electricity is transmitted to the conductive connector 630.

[0361] After the high-voltage power supply unit 520 and the first conductive component and electrode component 600 are connected, the assembly space 511 inside the entire insulating power supply shell 510 can be filled with power potting resin. After curing, it can achieve the functions of moisture protection and structural reinforcement.

[0362] When the electrode component 600 is connected to the power supply unit 500, the electrode component 600 is inserted into the first insertion hole 514 of the power supply insulating shell until the limiting protrusion 612 abuts against the outer side wall of the insulating power supply shell 510. Then, the first connector 531 is sleeved on the conductive connector 630, and the second connector 532 is screwed to press the first connector 531 to the end position of the electrode component 600. Finally, the first connector 531 is connected to the high voltage transformer 521 to realize the connection with the high voltage transformer 521.

[0363] In some embodiments of this disclosure, as shown in FIG30, the second connector 532 may include a plastic housing 5321. An insertion channel 5322 may be formed inside the plastic housing 5321. The insertion channel 5322 may extend from one end to the other along the axial direction of the plastic housing 5321. The second connector 532 is housed within the plastic housing 5321 primarily to facilitate twisting operations by the operator without the risk of electric shock.

[0364] In some embodiments, as shown in FIG30, an annular protrusion may be formed on the plastic housing 5321 to facilitate operation.

[0365] In some embodiments, as shown in FIG30, the second connector 532 may include a conductive kit 5323, which can be fitted into the insertion channel 5322. The contour of the conductive kit 5323 can be adapted to the insertion channel 5322 so that it is inserted into the insertion channel 5322, thereby realizing the corresponding power conduction and electrical conduction functions.

[0366] In some embodiments, as shown in FIG30, an internal thread may be formed on the conductive fitting 5323. The internal thread can be used for connection and engagement with the conductive connector 630. An external thread 631 is formed on the conductive connector 630. During engagement, the conductive fitting 5323 is screwed onto the external thread 631 of the conductive connector 630 via the internal thread.

[0367] In some embodiments, as shown in FIG30, a conductive flange 5324 may be formed on the conductive kit 5323. The conductive flange 5324 may be formed around the end of the conductive kit 5323. The conductive flange 5324 may be disposed in contact with the end face of the plastic shell 5321. The conductive flange 5324 may be used to be in contact with the first connector 531 for conductive bonding.

[0368] In some embodiments, as shown in FIG30, the conductive flange 5324 may be an annular flange formed along the end of the conductive kit 5323 away from the annular protrusion. The conductive flange 5324 may be attached to the end face of the plastic housing 5321 away from the annular protrusion. The conductive flange 5324 may be used to attach to the first connector 531 to achieve the conductive function.

[0369] During assembly, the second connector 532 is screwed onto the external thread 631 of the conductive connector 630 via the internal thread of the conductive kit 5323, and then attached to the first connector 531 via the conductive flange 5324, so that high-voltage and high-frequency electricity can be transmitted between the first connector 531, the second connector 532 and the conductive connector 630.

[0370] In some embodiments of this disclosure, as shown in FIG28, the grounding portion 400 may include an insulating grounding shell 410, and an accommodating space 411 may be formed inside the insulating grounding shell 410.

[0371] In some embodiments of this disclosure, the insulating grounding shell 410 can be injection molded from insulating materials, such as PP, ABS and other plastics.

[0373] In some embodiments, as shown in Figures 28 and 33, a second insertion hole 414 may be formed on the insulating grounding shell 410. The second insertion hole 414 can be used to insert one end of the grounding electrode component 600 that has a limiting protrusion 612, so that the grounding electrode component 600 is inserted above it and the end of the grounding electrode component 600 is supported.

[0374] In some embodiments, as shown in Figures 28 and 33, a second threaded connection hole 415 is formed on the insulating grounding shell 410. The second threaded connection hole 415 can be used to cooperate with the threaded connection portion 611 of the high-voltage electrode component 600. The high-voltage electrode component 600 can be screwed into the second threaded connection hole 415 through the threaded connection portion 611 to achieve connection and fixation with the insulating grounding shell 410, and the insulating grounding shell 410 provides support for one end of it.

[0375] In some embodiments, as shown in Figures 22 and 28, the grounding connection assembly 420 can be assembled into the receiving space 411, and the grounding connection assembly 420 can connect the electrode component 600 and the grounding wire 401. The grounding connection of the electrode component 600 is achieved through the grounding connection assembly 420.

[0376] In some embodiments, potting filler is filled within the receiving space 411 to seal the insulating ground housing 410.

[0377] In some embodiments, as shown in Figures 22 and 28, the potting filler can be a potting filling resin. After the second connecting component and the electrode component 600 are connected and fixed, the accommodating space 411 is filled with the potting filler, which can achieve the functions of moisture protection and structural reinforcement.

[0378] In some embodiments of this disclosure, as shown in FIG31, the grounding connection assembly 420 may include a third connector 421, which is conductive.

[0379] In some embodiments of this disclosure, as shown in FIG31, a plurality of second insertion portions 4211 may be formed on the third connector 421, the plurality of second insertion portions 4211 being used to insert conductive connectors 630 corresponding to a plurality of electrode components 600.

[0380] In some embodiments of this disclosure, as shown in FIG31, a grounding connection portion 4212 may be formed on the third connector 421, the grounding connection portion 4212 being used to connect with the grounding wire 401.

[0381] In some embodiments of this disclosure, as shown in FIG31, the second insertion part 4211 can be a second insertion hole, which is used to insert and cooperate with the conductive connector 630 to realize the connection with multiple electrode components 600 at one time.

[0382] In some embodiments, the grounding connection part 4212 can be a grounding connection nose, used to connect with the grounding wire 401 to realize the grounding function.

The fourth connector 422 may have the same structure as the second connector 532, and the cooperation method between the fourth connector and the third connector 421 is the same as the cooperation method between the second connector 532 and the first connector 531, which will not be described in detail here.

[0384] Plasma generators can be used not only in air conditioners, but also in other air purification devices or air handling equipment.

[0385] Among the air purification devices that utilize related technologies and achieve good purification effects, low-temperature plasma generators are the most common. The outer layer of the emitting electrode structure is generally a highly insulating quartz glass tube, but the internal electrodes vary considerably, mainly including the following:

[0386] The advantage of this structure is that the carbon powder can completely fill the quartz tube. However, the disadvantage is also obvious: the graphite powder is light and difficult to fill in the slender glass tube. It requires a continuous vibration filling process, which causes graphite dust, which has a serious adverse effect on the health of the operators.

[0387] Alternatively, metal powder can be directly filled into the glass tube. While this structure solves the problem of difficulty in filling due to its light weight, it also significantly increases the weight of the electrode structure. Furthermore, the particle size of the metal powder has a significant impact on the filling quality. Uneven filling will affect the parallelism of the electrode and the discharge effect. In addition, metal powder is expensive and not suitable for mass production.

[0388] To address the aforementioned issues, in some embodiments of this disclosure, an air purification device is proposed. This air purification device can be installed on an air conditioner to purify the airflow within the air conditioner.

[0389] In some embodiments of this disclosure, the air purification device may be a plasma generator, which is disposed in the airflow path of the air conditioner, such as in the return air section, the air outlet section, or inside the heat exchange duct of the air conditioner.

[0390] In some embodiments of this disclosure, as shown in FIG39, the air purification device may consist of a grounding part 400, a power supply part 500, and a transmitting electrode assembly laterally connected between the grounding part 400 and the power supply part 500.

[0391] In some embodiments of this disclosure, as shown in FIG39, the grounding part 400 can be connected to the ground, and the grounding part 400 can be used to realize the grounding function.

[0392] In some embodiments of this disclosure, as shown in FIG39, the power supply unit 500 can be electrically connected to the transmitting electrode assembly to provide high-frequency high-voltage electricity to the generating electrode assembly.

[0393] In some embodiments of this disclosure, as shown in FIG39, the transmitting electrode assembly is connected between the grounding part 400 and the power supply part 500. The transmitting electrode assembly may include electrode components 600, and multiple electrode components 600 are provided and arranged side by side.

[0394] In some embodiments of this disclosure, as shown in Figures 39 and 40, a plurality of side-by-side electrode components 600 are arranged to extend laterally along the direction from the power supply portion 500 to the ground portion 400.

[0395] In some embodiments of this disclosure, as shown in Figures 39 and 40, a plurality of electrode components 600 are parallel to each other and the plurality of electrode components 600 have identical structures.

[0396] During connection, among the multiple electrode components 600, one end of some electrode components 600 can be electrically connected to the power supply unit 500, and the other end of the electrode component 600 can be mechanically connected to the grounding unit 400. The two ends of the electrode component 600 are supported and fixed by the power supply unit 500 and the grounding unit 400, respectively. Another group of electrode components 600 can be connected to the grounding unit 400 to achieve grounding, and the other end of the electrode component 600 can be mechanically assembled to the power supply unit 500. The two ends of the electrode component 600 are supported and fixed by the power supply unit 500 and the grounding unit 400, respectively.

[0397] In some embodiments of this disclosure, as shown in Figures 39 and 40, a plurality of electrode components 600 electrically connected to the power supply unit 500 and a plurality of electrode components 600 electrically connected to the grounding unit 400 may be arranged alternately in sequence.

[0398] After the connection is completed, one end of one of the adjacent electrode components 600 can be electrically connected to the power supply unit 500, and the other end of the electrode component 600 can be mounted on the grounding unit 400. One end of the other electrode component 600 can be connected to the grounding unit 400 for grounding, and the other end of the electrode component 600 can be mounted on the power supply unit 500.

[0399] In some embodiments of this disclosure, as shown in Figures 39 and 40, the electrode component 600 electrically connected to the power supply unit 500 can form a high-voltage electrode component 600, and the electrode component 600 connected to the grounding unit 400 can form a grounding electrode component 600.

[0400] The high-voltage electrode component 600 is connected to the power supply unit 500, and the ground electrode component 600 is connected to the grounding unit 400. The high-voltage electrode component 600 and the ground electrode component 600 have different voltages. Therefore, there is a potential difference between adjacent high-voltage electrode components 600 and ground electrode components 600, and a high-frequency high-voltage electric field is formed. The high-frequency high-voltage electric field can break the molecular chains of odor molecules into small molecular fragments.

[0401] In some embodiments of this disclosure, as shown in Figures 40 and 41, a discharge gap 601 for gas molecules to flow through can be formed between two adjacent electrode components 600. The distance of the discharge gap 601 between the two electrode components 600 can be 2 to 5 mm.

[0402] When setting up, the number of electrode components 600 can be set to different numbers according to actual usage requirements. The number of electrode components 600 can be 4, 6 or 8, etc.

[0403] When indoor polluted air passes through the discharge gap 601 formed between the two electrode components 600, the molecular chains of harmful gases are directly broken under the action of the high-frequency high-voltage electric field.

[0404] Meanwhile, plasma is generated during the ionization of air by the electrode component 600. The plasma reacts with the broken small molecules to generate harmless substances such as carbon dioxide and water, thus eliminating odor molecules. At the same time, bacteria and viruses are also killed by the high voltage electric field when passing through the discharge gap 601, which directly destroys their cell walls and RNA, thus achieving a good odor removal and purification effect.

[0405] In some embodiments, as shown in Figures 39 and 40, in terms of structural arrangement, the grounding part 400 and the power supply part 500 are respectively arranged at both ends of the emitting electrode assembly. During connection, one end of a portion of the electrode component 600 is electrically connected to the power supply part 500, and the other end is assembled to the grounding part 400; one end of a portion of the electrode component 600 is connected to the grounding part 400 for grounding, and the other end is assembled to the power supply part 500. This not only achieves the support and fixation of the electrode component 600, but also achieves the integrated connection and assembly of multiple electrode components 600, the grounding part 400, and the power supply part 500. The entire connection structure is not only compact but also simpler, making it easier to assemble into the return air section or air outlet section of the air conditioner during use, facilitating assembly and installation.

[0406] The electrode component 600 has terminals for electrical connection wiring. During connection, some terminals of the electrode component 600 are connected to the power supply unit 500, and some terminals of the electrode component 600 are connected to the grounding unit 400.

[0407] In some embodiments of this disclosure, as shown in Figures 43, 44 and 50, the electrode component 600 may include an insulating dielectric shell 610 and a conductive component located inside the insulating dielectric shell.

[0408] In some embodiments of this disclosure, the insulating dielectric shell 610 may be an insulating dielectric shell with a certain length. In some embodiments of this application, the insulating dielectric shell 610 is a quartz glass tube with good insulation properties.

[0409] In some embodiments of this disclosure, the outer diameter of the insulating dielectric shell 610 is between 10 and 20 mm.

[0410] In some embodiments of this disclosure, the insulating dielectric shell 610 may be made of materials such as ceramic, PTFE or nylon.

[0411] In some embodiments of this disclosure, the insulating dielectric shell 610 may be an insulating dielectric tube with a port 616, through which conductive components are easily assembled into the tube.

[0412] In some embodiments of this disclosure, as shown in Figures 44, 50, and 51, the conductive component may include a conductive element 620. The conductive element 620 can be inserted into the interior of the insulating dielectric shell 610 from the port 616 along the axial direction of the insulating dielectric shell 610, making assembly convenient and quick.

[0413] In some embodiments of this disclosure, the conductive element 620 is hollow. The hollow interior of the conductive element 620 reduces material usage, resulting in a lighter overall weight, which in turn reduces the overall weight of the electrode component 600 and lowers production costs.

[0414] In some embodiments of this disclosure, as shown in Figures 51 and 52, a notch 621 extending axially may be provided on the sidewall of the conductive element 620. The notch 621 may be configured to radially deform the conductive element 620 assembled inside the insulating dielectric shell 610 so as to fit snugly against the inner wall of the insulating dielectric shell 610.

[0415] The insulating dielectric shell 610 has poor dimensional accuracy during high-temperature manufacturing. Therefore, when the internal dimensions of the insulating dielectric shell 610 are too small, the conductive component 620 will be difficult to insert into the insulating dielectric shell 610 if the dimensional accuracy of the conductive component 620 remains unchanged.

[0416] Furthermore, because low-temperature plasma electrodes have strict requirements for the parallelism between electrodes, non-parallelism will cause uneven discharge between the electrodes. When the inner wall size of the insulating dielectric shell 610 is too large, the conductive element 620 will wobble inside the insulating dielectric shell 610, causing the conductive element 620 to not be completely attached to the inner wall of the insulating dielectric shell 610, resulting in non-parallelism of the electrodes.

[0417] By providing a notch 621 along the axial direction of the conductive element 620, the notch 621 can communicate with the internal space of the conductive element 620, thereby allowing the conductive element 620 to deform through the notch 621.

[0418] During processing, wire cutting technology is used to extend the conductive component 620 axially to create a notch 621, so that the conductive component 620 will undergo elastic deformation in the radial direction under internal stress, thereby increasing the diameter of the conductive component 620. At this time, the conductive component 620 with the notch has a certain elastic deformation in the diameter direction.

[0419] When the actual inner diameter of the insulating dielectric shell 610 is larger than the reference inner diameter due to processing deviation, the conductive component 620 will expand radially to ensure that the outer wall of the conductive component 620 matches the inner diameter of the insulating dielectric shell 610 and remains in contact with the inner wall of the insulating dielectric shell 610.

[0420] Due to processing deviations, the actual inner diameter of the insulating dielectric shell 610 is smaller than the reference inner diameter. The conductive component 620 inserted inside it is compressed and deformed radially by the squeezing force of the inner wall of the insulating dielectric shell 610, resulting in a smaller size. This ensures a tight fit with the inner wall of the insulating dielectric shell 610, thereby guaranteeing the parallelism and installation accuracy of the plasma electrode.

[0421] In some embodiments of this disclosure, the conductive element 620 may be a metal element, the conductive element 620 may be conductive, and the conductive element 620 may be used to ensure that the electrode conducts normal electricity.

[0422] The conductive component 620 can be made of iron, copper, or stainless steel, which not only ensures conductivity but also a certain degree of hardness. During assembly, it can be quickly and easily inserted into the insulating dielectric shell 610 to achieve quick and convenient installation.

[0423] In some embodiments of this disclosure, the outer diameter of the conductive element 620 is 5% to 8% smaller than the inner diameter of the insulating dielectric shell 610, and the wall thickness is less than 0.7 mm, so that the deformation in the diameter direction after processing can meet the processing error requirements of the insulating dielectric shell 610.

[0424] In some embodiments of this disclosure, the outer diameter of the conductive element 620 may be less than 5%, 6%, or 8% of the inner diameter of the insulating dielectric shell 610. The wall thickness of the conductive element 620 may be 0.1 mm, 0.3 mm, 0.5 mm, or 0.6 mm.

[0425] The conductive component 620 should not expand too much during use, which would prevent it from being effectively inserted into the insulating dielectric shell 610; nor should it expand too little, which would cause the conductive component 620 to wobble inside the insulating dielectric shell 610. The diameter of the conductive component 620 is set such that its inner diameter is 5% to 8% smaller than the outer diameter of the insulating dielectric shell 610 to ensure that the conductive component 620 deforms within a suitable dimensional range.

[0426] In some embodiments of this disclosure, as shown in Figures 44, 51 and 53, the conductive component may include a conductive connector 630, which may be disposed within an insulating dielectric shell 610. One end of the conductive connector 630 may be connected to a conductive component 620, and the other end of the conductive connector 630 extends out of the insulating dielectric shell 610.

[0427] The conductive connector 630 is mainly used to realize electrical wiring connection. The conductive connector 630 can be used to connect to the power supply part 500 or to the grounding part 400.

[0428] In some embodiments of this disclosure, the conductive connector 630 may be a conductive post. The conductive connector 630 and the conductive member 620 are arranged side by side in the insulating medium shell 610 and extend outward from the port 616.

[0429] In some embodiments of this disclosure, as shown in Figures 51 and 53, an external thread 631 is provided on the protruding section of the conductive connector 630 to facilitate subsequent wiring operations.

[0430] In some embodiments of this disclosure, as shown in Figures 50, 51 and 52, the conductive element 620 may have a first end 623 and a second end 624 located at both ends thereon, and a notch 621 may extend from the first end 623 to the second end 624 along the axial direction of the conductive element 620.

[0431] In some embodiments of this disclosure, as shown in Figures 51 and 52, the notch 621 can be an elongated notch formed along the overall length of the conductive member 620. The elongated notch ensures that the conductive member 620 can deform radially at various points along its length, ensuring that each point of the conductive member 620 remains in contact with the inner wall of the insulating dielectric shell 610, and ensuring the parallelism and installation accuracy of the electrode component 600.

[0432] In some embodiments of this disclosure, the conductive element 620 may be a conductive sleeve, and the two ends of the conductive element 620 are formed with a first through-hole and a second through-hole, and the notch 621 may extend from the first through-hole to the position of the second through-hole.

[0433] In some embodiments of this disclosure, the two ends of the conductive element 620 may not be continuous. Hollowed-out portions may be formed on the end faces of the two ends of the conductive element 620 at positions corresponding to the notches 621, so as to ensure that the conductive element 620 can undergo normal radial deformation.

[0434] In some embodiments of this disclosure, as shown in FIG52, the conductive element 620 has a first end 623 and a second end 624 disposed opposite to the first end 623.

[0435] In some embodiments of this disclosure, as shown in FIG56, the notch 621 may include a first deformable opening 6211, which may extend from the first end 623 of the conductive member 620 along the axial direction of the conductive member 620 toward the second end 624.

[0436] In some embodiments of this disclosure, as shown in FIG56, the notch 621 may include a second deformable opening 6212, and the second deformable opening 6212 and the first deformable opening 6211 may be arranged staggered in the circumferential direction of the conductive member 620. The second deformable opening 6212 may extend from the second end 624 of the conductive member 620 toward the first end 623 in the axial direction of the conductive member 620. The end of the second deformable opening 6212 away from the second end 624 may be flush with the end of the first deformable opening 6211 away from the first end 623.

[0437] The first deformation opening 6211 and the second deformation opening 6212, which are arranged in a staggered manner, form a notch 621 arranged along the axial direction of the conductive member 620.

[0438] The first deformation opening 6211 causes the conductive element 620 to deform on the conductive element 620 segment corresponding to the first deformation opening. The second deformation opening causes the conductive element 620 to deform on the conductive element 620 segment corresponding to the second deformation opening 6212. The cooperation of the two ensures that the entire conductive element 620 deforms in the radial direction to fit snugly against the inner wall of the insulating dielectric shell 610.

[0439] In some embodiments of this disclosure, as shown in FIG52, the conductive member 620 may include a sleeve body. A first through portion 625 and a second through portion 626 are formed at both ends of the sleeve body. The first through portion 625 and the second through portion 626 can communicate with the internal space of the sleeve body. The first through portion 625 is closer to the conductive connector 630 than the second through portion 626.

[0440] In some embodiments of this disclosure, as shown in FIG52, the first through portion 625 can be a first through opening, and the second through portion 626 can be a second through opening. Both are connected to the internal space of the sleeve body to form a conductive kit 5323.

[0441] In some embodiments of this disclosure, as shown in Figures 52 and 53, a connecting portion 627 may be formed around the first through portion 625. The connecting portion 627 extends axially along the insulating dielectric shell 610 to the conductive connector 630 and connects to it. The first through portion 625 is close to the conductive connector 630, and by forming the connecting portion 627 around it, a connection with the conductive connector 630 can be achieved at a relatively short distance. The connection between the connecting portion 627 and the conductive connector 630 ensures the continuity of the electrical transmission path and guarantees electrical transmission.

[0442] In some embodiments of this disclosure, multiple connecting portions 627 may be provided, and these multiple connecting portions 627 may be arranged circumferentially along the first through portion 625. The connection between the multiple connecting portions 627 and the conductive connector 630 ensures a robust connection.

[0443] During molding, a portion of the conductive part 620 can be cut off from the middle using wire cutting at one end, leaving a connecting part 627 on each side. The two connecting parts 627 are symmetrically distributed on both sides of the notch 621.

[0444] In some embodiments of this disclosure, as shown in Figures 52 and 53, the connecting portion 627 may include an inclined connecting arm 6271. The inclined connecting arm 6271 may be inclinedly arranged from the conductive member 620 to the conductive connector 630. The inclined connecting arm 6271 may be used to realize the transition of the connection from the conductive member 620 to the conductive connector 630.

[0445] In some embodiments of this disclosure, as shown in Figures 52 and 53, the connecting portion 627 may include a straight connecting arm 6272, which may be connected to an inclined connecting arm 6271. The straight connecting arm 6272 may conform to the outer wall of the conductive connector 630 and be welded to it. The straight connecting arm 6272 can be welded to the outer wall of the conductive connector 630 to achieve connection with the conductive connector 630.

[0446] During connection, the conductive connector 630 is inserted into the middle position of the multiple connecting parts 627, and the multiple connecting parts 627 can be welded to the conductive connector 630 at the same time by spot welding.

[0447] In some embodiments of this disclosure, as shown in Figures 54 and 55, a raised positioning protrusion 613 may be formed on the inner wall of the insulating dielectric shell 610. The positioning protrusion 613 may be used in the insertion notch 621 to guide and position the installation of the conductive element 620.

[0448] After the conductive component 620 is machined with a notch 621, there is no conductive material at the notch 621. Therefore, plasma discharge cannot occur at the notch 621. When arranging multiple plasma electrode components 600, the notch 621 cannot be aligned with another plasma electrode component 600; therefore, the notch 621 needs to be positioned.

[0449] By using the positioning protrusion 613 designed at a specific position inside the insulating dielectric shell 610, when installing the conductive component 620, the notch 621 is aligned with the positioning protrusion 613, and the conductive component 620 is inserted into the insulating dielectric. The positioning protrusion 613 guides the notch 621, so that all the notches 621 are inserted into the insulating dielectric shell 610 in the same direction, and the notches 621 of the multiple electrode components 600 all face the same direction.

[0450] In some embodiments of this disclosure, as shown in Figures 44 and 51, the insulating dielectric shell 610 may have a first connection end 614, and a limiting protrusion 612 may be provided on the insulating dielectric shell 610 near the first connection end 614 for positioning its position when assembled to the power supply part 500 or the grounding part 400.

[0451] During assembly, the insulating dielectric shell 610 is inserted into the power supply section 500 or the grounding section 400. The insertion position of the insulating dielectric shell 610 can be limited by the limiting protrusion 612, so that the insulating dielectric shell 610 can be quickly assembled into place.

[0452] In some embodiments of this disclosure, as shown in FIG51, the insulating dielectric shell 610 may include a second connecting end 615, at which a threaded connecting portion 611 may be formed for connection and engagement with the grounding portion 400 or the power supply portion 500. The threaded connecting portion 611 is a threaded connecting hole, and the threaded connecting portion 611 is used to be screwed into the power supply portion 500 or the grounding portion 400 for fixation.

[0453] In some embodiments of this disclosure, as shown in FIG50, the insulating medium shell 610 may include a fixed sealing assembly, which may include a blocking component 640. The blocking component 640 may be assembled inside the insulating medium shell 610 and may be located between the second connecting end 615 and the conductive element 620.

[0454] The blocking component 640 can be a plug, mainly serving a sealing function. The plug also has a certain length to increase the creepage distance of the electrode component 600 during use, thus improving safety. The insulating dielectric shell 610 and the plug are connected by high-temperature welding. The wall thickness should be between 1 and 1.5 mm.

[0455] During assembly, the conductive component 620 is inserted into the insulating medium shell 610 through the port 616 until the conductive component 620 contacts the bottom plug.

[0456] In some embodiments of this disclosure, as shown in FIG50, the insulating dielectric shell 610 may include a sealing member 650, which may be inserted into the insulating dielectric shell 610. The sealing member 650 may be sleeved at the connection position between the conductive member 620 and the conductive connector 630. The sealing member 650 may be a sealing rubber plug.

[0457] After inserting the conductive component 620 into the bottom of the insulating medium component, the sealing component 650 is pushed into the insulating medium shell 610 using a ring tool until it reaches the welding position of the conductive component 620 and the conductive connector 630. Its main function is to prevent the sealant from the subsequent process from flowing into the interior of the conductive component 620.

[0458] In some embodiments of this disclosure, as shown in FIG50, a sealing filler may be filled inside the insulating medium shell 610, and the sealing filler may be located in the region between the seal 650 and the first connection end 614.

[0459] In some embodiments of this disclosure, as shown in FIG50, the sealing filler can be epoxy resin sealant. The epoxy resin sealant is poured into the remaining space of the insulating medium shell 610 and flush with the opening 616. After curing, the assembly of the electrode component 600 is completed.

[0460] In some embodiments of this disclosure, the power supply unit 500 includes an insulating power supply housing 510 and a high-voltage power supply unit 520 and an electrical connection assembly 530 assembled within the insulating power supply housing 510.

[0462] The insulating power supply housing 510 can be injection molded from insulating materials such as PP, ABS and other plastics. The main function of the insulating power supply housing 510 is to provide support for the installation of the electrode components 600 of the plasma generator. At the same time, the insulating power supply housing 510 is also used to encapsulate electrical components such as the high-voltage power supply unit 520 assembled inside it.

[0463] In some embodiments of this disclosure, as shown in Figures 43, 44 and 45, a first flange portion 512 may be extended from the insulating power housing 510, and a first mounting hole 513 may be provided on the first flange portion 512.

[0464] During connection, the insulating power housing 510 can be locked and fixed to the air conditioner by passing a locking screw through the first mounting hole 513.

The electrical connection component 530 can be used to transmit power from the high-voltage power supply unit 520 to the electrode component 600, which can be a high-voltage electrode component 600.

[0470] The electricity transmitted from the outside to the high voltage transformer 521 will be transmitted to the high voltage electrode component 600 connected to it through the first conductive component, and finally the high frequency and high voltage electricity will be transmitted to the high voltage electrode component 600.

A connection hole is provided on the electrical connection nose for connecting to the high-voltage transformer 521 via a wire.

[0477] In some embodiments of this disclosure, as shown in Figures 43 and 48, the first conductive component may include a second connector 532, which is screwed onto the conductive connector 630 and fits against the first connector 531 to press and fix it to the end face of the insulating dielectric shell 610.

[0495] In some embodiments of this disclosure, as shown in Figures 40 and 46, a second threaded connection hole 415 may be formed on the insulating grounding shell 410. The second threaded connection hole 415 can be used to cooperate with the threaded connection portion 611 of the high-voltage electrode component 600.

[0504] In some embodiments of this disclosure, as shown in FIG40, the fourth connector 430 may have the same structure as the second connector 532, and the cooperation method between the fourth connector 430 and the third connector 421 may be the same as the cooperation method between the second connector 532 and the first connector 531, which will not be described in detail here.

[0505] Air handling equipment of related technologies purifies the air flowing through it to obtain clean and fresh air by installing an air purification device to remove odors at the return air section.

[0506] Air purification devices based on related technologies include adsorption devices with adsorption functions. They achieve the effect of adsorbing and removing odors by coating the top with an adsorbent material. However, this method of adsorbing odors cannot continue to adsorb once the adsorption is saturated.

[0507] With continuous development, plasma generators have emerged. These generators generate electricity to break down and remove odor molecules. However, plasma generators produce a large amount of ozone during use, and excessive ozone content can be harmful to the human body.

[0508] In some applications, plasma generators and ozone decomposition filters are used together. During assembly, the plasma generator and ozone decomposition filter are installed onto the fixed frame from top to bottom. When the ozone decomposition filter becomes saturated, it needs to be removed and replaced. Since the plasma generator is fixed to the front of the ozone decomposition filter, the plasma generator needs to be removed and replaced when the ozone decomposition filter is replaced. The replacement operation remains the same.

[0509] To address the aforementioned problems, in some embodiments of this disclosure, an air conditioner is proposed, as shown in Figures 20 and 57. The air conditioner may include a housing 100. The housing 100 constitutes the outer casing of the indoor unit of the air conditioner, and a heat exchange air duct 130 is formed inside the housing 100.

[0510] In some embodiments, as shown in FIG57, a return air section 110 may be formed on the housing 100. The return air section 110 is an air inlet formed on the housing 100 so that external airflow can enter the interior of the housing 100.

[0511] In some embodiments, as shown in FIG57, an air outlet 120 may be formed on the housing 100. The air outlet 120 is an air outlet formed on the housing 100 and is used to discharge the heat-exchanged airflow.

[0512] In some embodiments, as shown in FIG57, a heat exchange duct 130 may be formed between the return air section 110 and the outlet air section 120. The heat exchange duct 130 can be used to circulate airflow. The airflow enters from the return air section 110, flows through the heat exchange duct 130, and then flows out from the outlet air section 120. The airflow flowing into the heat exchange duct 130 undergoes heat exchange inside it.

[0513] In some embodiments, as shown in FIG57, the air conditioner may include an evaporator 240. The evaporator 240 may be arranged in the heat exchange duct 130 for heat exchange with the airflow flowing through the heat exchange duct 130. Through heat exchange between the evaporator 240 and the airflow in the heat exchange duct 130, the airflow can be heated or cooled, thereby making the airflow blown out from the air outlet 120 a heated or cooled airflow, so as to achieve the cooling or heating effect of the air conditioner accordingly.

[0514] In some embodiments, as shown in FIG57, the air conditioner may include an air supply device 140. The air supply device 140 may be disposed within the heat exchange duct 130 for driving airflow to circulate within the heat exchange duct 130 and controlling the flow rate of the airflow within the heat exchange duct 130. The air supply device 140 draws airflow from the return air section 110 into the heat exchange duct 130 to exchange heat with the evaporator, and then delivers the airflow from the air outlet section 120, thus providing the power for the airflow circulation.

[0515] In some embodiments, the air conditioner may include a refrigeration cycle loop. The refrigeration cycle loop may be formed by connecting a compressor, a main expansion valve, a condenser, and an evaporator via refrigerant piping. The refrigeration cycle of the air conditioner is executed by using the compressor, condenser, main expansion valve, and evaporator 240. The refrigeration cycle may include a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0516] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0517] The main expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant that expanded in the main expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0518] In some embodiments, the outdoor unit of an air conditioner refers to the portion of the refrigeration cycle that includes a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in either the indoor or outdoor unit.

[0519] In some embodiments, the indoor heat exchanger and the outdoor heat exchanger serve as either a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger serves as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0520] In some embodiments, the air conditioner may include an air purification device for purifying the airflow passing through the air conditioner.

[0521] In some embodiments, as shown in Figures 57 and 58, the air purification device may include a base frame 300, which may be assembled inside the return air section 110 or the heat exchange air duct 130, and may be connected and fixed to the housing 100.

[0522] In some embodiments, as shown in Figures 57, 58, and 59, the air purification device may include a plasma generator 30 and an ozone adsorption and decomposition component 50. The plasma generator 30 and the ozone adsorption and decomposition component 50 may be sequentially disposed on the substrate frame 300 along the airflow direction.

[0523] In some embodiments, as shown in Figures 57, 58 and 59, the plasma generator 30 can be fixedly connected to the substrate frame 300 for purifying the airflow flowing through it.

[0524] When the plasma generator 30 discharges, it can form a high-frequency, high-voltage electric field. This high-frequency, high-voltage electric field can break down the molecular chains of odor molecules into small molecular fragments.

[0525] During the ionization of air by the plasma generator 30, plasma is also generated, which reacts with the broken small molecular fragments to produce harmless substances such as carbon dioxide and water, thus achieving the effect of completely eliminating odor molecules. It has a good effect on removing odors and purifying the air.

[0526] However, during the use of the plasma generator 30, a large amount of ozone will be generated. In order to prevent a large amount of ozone from flowing into the room with the air conditioner and causing harm to the human body, it is necessary to install corresponding components for ozone adsorption and decomposition to eliminate ozone.

[0527] In some embodiments, as shown in Figures 57, 58 and 59, an ozone adsorption and decomposition component 50 is provided on the substrate frame 300. The ozone adsorption and decomposition component 50 is located downstream of the airflow path and can at least adsorb and decompose the ozone generated by the plasma generator 30 located upstream.

[0528] In some embodiments, as shown in Figures 57 and 59, the ozone adsorption and decomposition component 50 is removably mounted on the base frame 300. By making the ozone adsorption and decomposition component 50 removably mounted on the base frame 300, the ozone adsorption and decomposition component 50 can be easily replaced.

[0529] During assembly and fixing, the plasma generator 30 is fixed on the base frame 300, and the ozone adsorption and decomposition component 50 is removable and mounted on the base frame 300. In this way, when the ozone adsorption and decomposition component 50 is saturated and needs to be replaced, it is not necessary to disassemble the plasma generator 30 for replacement. Only the ozone adsorption and decomposition component 50 needs to be pulled out, making the replacement and disassembly more convenient and quick.

[0530] In some embodiments, as shown in Figures 59, 63 and 64, a limiting stop 600 may be provided on the base frame 300, the limiting stop 600 may have a locking position and an unlocking position.

[0531] When the limiting stop is in the locked position, the ozone adsorption and decomposition component 50 assembled in the base frame 300 can be limited, thus ensuring that the ozone adsorption and decomposition component 50 assembled in the base frame 300 will not fall out of the base frame 300.

[0532] When the limiting stop is in the unlocked position, the limiting stop 600 can be released from the ozone adsorption and decomposition component 50 assembled in the base frame 300. Adjusting the limiting stop 600 to the unlocked position allows for easy pulling and pulling of the ozone adsorption and decomposition component 50 for replacement.

[0533] In some embodiments of this disclosure, as shown in FIG58, the base frame 300 may include a first side portion 310 disposed along a first direction and a second side portion 320 disposed along a second direction.

[0534] In some embodiments of this disclosure, as shown in FIG58, the first side portion 310 can be the first side of the base frame 300. The first side portion 310 can extend along the length direction of the base frame 300. There can be two first side portions 310, and the two first side portions 310 can be arranged opposite to each other.

[0535] In some embodiments of this disclosure, as shown in FIG58, the second side portion 320 may be connected to the first side portion 310, and the second side portion 320 may be disposed along a second direction, which is perpendicular to the first direction.

[0536] In some embodiments of this disclosure, as shown in FIG58, the second side portion 320 can be the second side of the base frame 300. The second side portion 320 can extend along the width direction of the base frame 300, and its two ends are respectively connected to the two ends of the first side portion 310. There can be two second side portions 320, and the two second side portions 320 can be arranged opposite to each other.

[0537] In some embodiments of this disclosure, as shown in FIG57, when the base frame 300 is assembled onto the air conditioner, the base frame 300 can be arranged laterally in the return air section 110 or heat exchange air duct 130 of the air conditioner. The width direction of the base frame 300 is in the same direction as the height direction of the air conditioner casing 100, that is, the width direction corresponds to the up and down direction, and the length direction corresponds to the left and right direction.

[0538] In some embodiments, as shown in Figures 57 and 59, the ozone adsorption and decomposition component 50 can slide relative to the substrate frame 300 along the direction of the first side portion 310. That is, the ozone adsorption and decomposition component 50 is slidably inserted into the substrate frame 300 along the length direction of the substrate frame 300. In other words, the ozone adsorption and decomposition component 50 can be inserted into the substrate frame 300 along the left or right side direction.

[0539] In some embodiments, the limiting stop 600 can be positioned on the left or right side to limit the ozone adsorption and decomposition component 50.

[0540] In some embodiments, as shown in Figures 57 and 59, the ozone adsorption and decomposition component 50 can slide relative to the substrate frame 300 along the direction of the second side portion 320. That is, the ozone adsorption and decomposition component 50 can be slidably inserted into the substrate frame 300 along the width direction, i.e., the ozone adsorption and decomposition component 50 can be inserted into the substrate frame 300 along the vertical direction.

[0541] When the air conditioner is installed on the indoor ceiling, most of its casing 100 is embedded inside the ceiling. The ozone adsorption and decomposition component 50 is designed to be pulled out in the left and right direction, so the ceiling needs to be disassembled for replacement.

[0542] By configuring the ozone adsorption and decomposition component 50 to slide and insert into the base frame 300 along the height direction of the housing 100, the ozone adsorption and decomposition component 50 can be pulled down from the bottom of the base frame 300 for replacement, without the need to disassemble the ceiling, making the replacement operation convenient.

[0543] In some embodiments of this disclosure, as shown in FIG59, the ozone adsorption and decomposition assembly 50 may include a first adsorption and decomposition mesh 51. The first adsorption and decomposition mesh 51 may be provided with ozone adsorption and decomposition substances, and the first adsorption and decomposition mesh 51 is retractably disposed within the substrate frame 300.

[0544] In some embodiments, the first adsorption and decomposition mesh 51 can be a catalytic oxidation filter, which can be used to adsorb or catalytically oxidize and decompose ozone; or, the first adsorption and decomposition mesh 51 can be an adsorption filter, which can not only adsorb ozone, but also adsorb other odor molecules to achieve the deodorization effect of adsorbing ozone and odor molecules and removing odors.

[0545] In some embodiments, the first adsorption and decomposition mesh 51 is removably disposed within the substrate frame 300, and can be disassembled and replaced after the first adsorption and decomposition mesh 51 is saturated.

[0546] In some embodiments, as shown in FIG59, the ozone adsorption and decomposition assembly 50 may include a second ozone decomposition net 52, which is removably disposed within the substrate frame 300 and is capable of decomposing ozone in the airflow after passing through the first adsorption and decomposition net 51.

[0547] In some embodiments, an ozone decomposition catalyst may be coated on the second ozone decomposition mesh 52. The second ozone decomposition mesh 52 can be used to further adsorb and decompose the ozone that has been deodorized by the first adsorption and decomposition mesh 51, so as to assist the first adsorption and decomposition mesh 51 in decomposing the residual ozone molecules, reducing the ozone concentration, and ensuring the safety of the airflow blown out by the air conditioner.

[0548] In addition, the plasma generated by the plasma generator 30 can decompose the odor molecules adsorbed in the first adsorption and decomposition net 51, thereby regenerating them.

[0549] In some embodiments, as shown in Figures 60 and 61, a first sliding track portion 371 may be formed on the substrate frame 300. Two first sliding track portions 371 may be provided, arranged opposite to each other on the substrate frame 300. The first sliding track portions 371 may extend along the direction of the second side portion 320, and both sides of the first adsorption and decomposition mesh 51 may be inserted into the two first sliding track portions 371 respectively, and inserted into the substrate frame 300 along the first sliding track portions 371.

[0550] In some embodiments, as shown in Figures 60 and 61, a second sliding track portion 372 may be formed on the base frame 300. Two second sliding track portions may be provided, and the two second sliding track portions may be arranged opposite to each other on the base frame 300. The second sliding track portions 372 may extend along the direction of the second side portion 320. The two sides of the second ozone decomposition net 52 may be respectively inserted into the two second sliding track portions 372, and inserted into the base frame 300 along the second sliding track portions 372.

[0551] The first sliding track 371 can guide the assembly of the first adsorption and decomposition net 51 to ensure that the first adsorption and decomposition net 51 can be quickly and accurately assembled into place.

[0552] The second sliding track 372 can guide the assembly of the second ozone decomposition net 52 to ensure that the second ozone decomposition net 52 can be assembled quickly and accurately.

[0553] In some embodiments of this disclosure, as shown in Figures 57 and 59, an insertion portion 330 for inserting an ozone adsorption and decomposition component 50 may be formed on the substrate frame 300. The insertion portion 330 can be used to insert the ozone adsorption and decomposition component 50.

[0554] In some embodiments, as shown in Figures 57 and 59, the insertion part 330 can be an insertion port for inserting the first adsorption decomposition net 51 and the second ozone decomposition net 52.

[0555] In some embodiments, as shown in Figures 57 and 59, the limiting stop 370 may be located at a peripheral position of the insertion portion 330, and the ozone adsorption and decomposition assembly 50 inserted into the base frame 300 may be limited by abutting against the insertion portion 330.

[0556] In some embodiments, as shown in Figures 59, 63 and 64, during connection, the limiting stop 600 can be rotatably connected to the base frame 300 via a locking member 3701 screwed into the base frame 300.

[0557] In some embodiments, the locking member 3701 may be a locking screw. A threaded hole may be provided in the base frame 300, and after the locking member 3701 passes through the limiting stop member 600, it is locked and fixed in the threaded hole of the base frame 300.

[0558] In some embodiments, the locking member 3701 has a locked state and a loosened state. When the locking member 3701 is in the locked state, the limiting stop member 600 is pressed at the locked position and abuts against the insertion portion 330, thereby limiting the ozone adsorption and decomposition assembly 50 inserted into the base frame 300.

[0559] When the locking member 3701 is in the loosened state, the limiting stop member can rotate relative to the base frame 300 to be in the unlocked position, thereby releasing the limitation on the ozone adsorption and decomposition component 50.

[0560] When using it, first loosen the locking part 3701, then rotate the limiting stop 600 and insert the ozone adsorption and decomposition component 50. After it is inserted into place, rotate the limiting stop 600 to the insertion part 330 position, and then tighten the locking part 3701.

[0561] When disassembly is required, loosen the locking part 3701, rotate the limiting stop 600 away from the insertion part 330, and then pull out the ozone adsorption and decomposition component 50.

[0562] In some embodiments, as shown in Figures 63 and 64, the limiting stop 370 may include a stop body portion and side wings located on both sides thereon. The limiting stop 370 can be easily rotated via the side wings.

[0563] In some embodiments of this disclosure, as shown in FIG62, a power supply receiving portion is formed on one side of the base frame 300. The power supply receiving portion can be a power supply receiving shell, and a cavity can be formed inside the power supply receiving portion.

[0564] In some embodiments of this disclosure, as shown in Figures 62 and 65, a support member 810 may be provided inside the power supply housing, and the support member 810 may protrude from the bottom wall of the power supply housing.

[0565] In some embodiments of this disclosure, as shown in Figures 62 and 65, a power supply component 820 may be provided within the power supply housing, and the power supply component 820 may be fixedly assembled within the support component 810. Specifically, the power supply component 820 is fixedly secured within the support component 810 by screws.

[0566] In some embodiments, the support member 810 may be a support plate, which is locked and fixed to the bottom wall of the power supply housing. A boss is formed on the top of the support member 810 for mounting the power supply component 820 to avoid direct contact between the power supply component 820 and the bottom wall of the power supply housing.

[0567] In some embodiments of this disclosure, as shown in Figures 65 and 66, the base frame 300 may include a frame body and a frame extension.

[0568] In some embodiments of this disclosure, as shown in Figures 65 and 66, an airflow passage 340 is formed on the frame body to facilitate airflow.

[0569] In some embodiments of this disclosure, as shown in Figures 65 and 66, the frame body may include a first frame member 381 and a second frame member 382, ​​wherein the second frame member 382 may be disposed opposite to the first frame member 381.

[0570] The first frame member 381 can be the top plate of the first frame, and the second frame member 382 can be the bottom plate of the second frame, with the two arranged opposite each other.

[0571] In some embodiments of this disclosure, as shown in Figures 65 and 66, the frame body may include a third frame member 383, which may be connected to one end of the first frame member 381 and the second frame member 382. The third frame member 383 may be a third frame side plate, and may be vertically arranged between the first frame member 381 and the second frame member 382 and connect the two.

[0572] In some embodiments of this disclosure, as shown in Figures 65 and 66, the frame body may include a frame extension 384, which may extend from the first frame member 381 to the position of the second frame member 382 and be disposed opposite to the third frame member 383. The frame extension 384 may be a frame extension plate formed by bending from the first frame member 381.

[0573] In some embodiments of this disclosure, as shown in Figures 65 and 66, the first frame member 381, the second frame member 382, ​​the third frame member 383 and the frame extension 384 may be provided with an airflow passage 340 to facilitate airflow. The airflow passage 340 can be an airflow passage hollow area to facilitate airflow.

[0574] In some embodiments, as shown in Figures 65 and 66, a housing component may be provided on the frame body, and the housing component is connected to the frame body to form a power supply housing.

[0575] During the molding process, the frame body can be directly integrally formed from sheet metal parts, and the shell components can be connected to the frame body, which simplifies the manufacturing process.

[0576] In some embodiments, as shown in Figures 58, 65, and 66, the housing assembly may include a cover member 830 and a base plate member 840. The frame body may include a fourth frame member 385. The fourth frame member 385 may be connected between the first frame member 381 and the second frame member 382, ​​and is disposed opposite to the third frame member 383. The fourth frame member 385 may be a fourth frame side plate, and the fourth frame member 385 may be disposed opposite to the third frame side plate.

[0577] A surrounding panel member is formed by connecting the housing member 830, the frame extension 384, the first frame member 381, the second frame member 382, ​​and the fourth frame member 385 to form the periphery of the power supply receiving part. The housing member 830 is connected to the top position of the surrounding panel member to achieve sealing of the top position.

[0578] The base plate component 840 is connected to the bottom of the enclosure component to achieve a seal at the bottom, ultimately forming a completely enclosed power supply housing to seal the power supply placed inside and prevent moisture or dust from entering.

[0579] In some embodiments of this disclosure, as shown in Figures 58 and 59, the plasma generating apparatus 30 may include a first insulator portion 910. The plasma generating apparatus 30 may include a second insulator portion 920. The plasma generating apparatus 30 may include an electrode component 930 connected between the first insulator portion 910 and the second insulator portion 920.

[0580] In some embodiments of this disclosure, the first insulator portion 910 may be assembled onto the frame body.

[0581] The first insulating part 910 can be a first insulating block. The first insulating part 910 can be injection molded from insulating material, such as PP, ABS and other plastics. The main function of the first insulating part 910 is to provide support for the installation of the electrode component 930 of the plasma generator 30.

[0582] A first insertion portion 911 and a first threaded connection portion 912 may be provided on the first insulator portion 910.

[0583] The first insertion part 911 is a first insertion hole, and the first threaded connection part 912 is a first threaded connection hole. The first insertion hole and the first threaded connection hole are used to connect with the electrode component 930.

[0584] In some embodiments of this disclosure, as shown in Figures 58 and 59, the plasma generating apparatus 30 may include a second insulator portion 920, which may be mounted on the frame body and may be arranged opposite to the first insulator portion 910 on both sides of the airflow passage 340.

[0585] The second insulating part 920 can be a second insulating block. The second insulating part 920 can be injection molded from insulating material, such as PP, ABS and other plastics. The main function of the second insulating part 920 is to provide support for the installation of the electrode component 930 of the plasma generator 30.

[0586] In some embodiments, a second insertion portion and a second threaded connection portion may be provided on the second insulator portion 920. The second insertion portion may be a second insertion hole, and the second threaded connection portion may be a second threaded connection hole. The second insertion hole and the second threaded connection hole are used to connect with the electrode component 930.

[0587] In some embodiments, as shown in Figures 58 and 59, multiple electrode components 930 can be provided, and these multiple electrode components 930 can be arranged in parallel between the first insulator portion 910 and the second insulator portion 920. During installation, the number of electrode components 930 can be set differently according to actual usage requirements; four, six, or eight electrode components 930 are all acceptable.

[0588] The electrode component 930 can be sealed at the airflow passage 340, and a discharge gap 940 can be formed between adjacent electrode components 930. The distance of the discharge gap 940 between the two electrode components 930 is 2 to 5 mm.

[0589] Multiple electrode components 930 are arranged side by side and sealed at the airflow passage 340. When the airflow of the air conditioner passes through the electrode components 930, it will pass through the discharge gap 940 between the two electrode components 930. Under the action of the high-frequency high-voltage electric field, the molecular chains of harmful gases are directly broken.

[0590] Meanwhile, plasma is generated during the ionization of air by the electrode component 930. The plasma reacts with the broken small molecules to generate harmless substances such as carbon dioxide and water, thus eliminating odor molecules. At the same time, when bacteria and viruses pass through the discharge gap 940, their cell walls and RNA are directly destroyed by the high-voltage electric field and killed, thus achieving a good odor removal and purification effect.

[0591] In some embodiments of this disclosure, as shown in FIG69, the electrode component 930 may include an insulating dielectric tube and a conductive component disposed within the insulating dielectric tube, the conductive component being used to realize the conductive function of the electrode component 930.

[0592] In some embodiments, as shown in FIG69, the insulating dielectric tube is provided with limiting protrusions 9311 and connecting threads 9312 at both ends for connecting and engaging with the first insulator portion 910 and the second insulator portion 920. The limiting protrusions 9311 can position the electrode component 930 during assembly, allowing it to be quickly inserted into place.

[0593] During assembly, one end of the electrode component 930 is inserted into the first insertion hole or the second insertion hole, and the other end of the electrode component 930 is screwed into the second threaded connection hole or the first threaded connection hole through the connecting thread 9312, so that the electrode component 930 is supported and fixed by the first insulating part 910 and the second insulating part 920 at both ends.

[0594] By configuring each of the multiple electrode components 930 to be inserted into and threadedly connected to the first insulator portion 910 and the second insulator portion 920, each electrode component 930 can be easily disassembled and replaced. If one of the electrode components 930 is damaged during transportation, it can be replaced individually without replacing the entire plasma generator 30, thus reducing maintenance costs.

[0595] In some embodiments of this disclosure, as shown in FIG69, the conductive component may include a conductive element 932 and a conductive connector 933. The conductive connector 933 may extend from the insulating dielectric tube 931, and the extended end of the conductive connector 933 is provided with an external thread.

[0596] In some embodiments of this disclosure, as shown in Figures 59 and 67, after multiple electrode components 930 are connected to the first insulator portion 910 and the second insulator portion 920, one end of one of the adjacent electrode components 930 can pass through the second insulator portion 920 and be electrically connected to the power supply component 820 through the electrical connection assembly 950, while the other end of the electrode component 930 is assembled onto the first insulator portion 910.

[0597] The electrode component 930, which is electrically connected to the power supply component 820, forms a first electrode component 930, which can receive high-frequency high-voltage electricity from the power supply component 820.

[0598] In some embodiments of this disclosure, as shown in Figures 59 and 68, in adjacent electrode components 930, one end of another electrode component 930 passes through the first insulator portion 910 and is connected to the base frame 300 through the grounding connection assembly 960, and the other end is assembled onto the second insulator portion 920. The electrode component 930 connected to the base frame 300 forms the second electrode component 930.

[0599] In some embodiments, as shown in FIG59, the first electrode component 930 passes through the second insulator portion 920 and is connected to the power supply component 820, and the second electrode component 930 is mounted on the second insulator portion 920 and connected to the substrate frame 300 to achieve grounding. The first electrode component 930 and the second electrode component 930 have different voltages. Therefore, a potential difference can exist between adjacent first electrode components 930 and second electrode components 930, forming a high-frequency, high-voltage electric field.
