For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] The air treatment device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0051] like Figure 1-Figure 4 As shown, an air treatment device 100 according to an embodiment of the present invention includes a housing 1, a pulse lamp module 2 and a plasma module 3. The housing 1 has an air duct 11 and an air inlet 12 and an air outlet 13 connected to the air duct 11. It can be understood that when the air treatment device 100 is running, the air in the space where the air treatment device 100 is located enters the air duct 11 from the air inlet 12, flows in the air duct 11, and finally blows to the space where the air treatment device 100 is located through the air outlet 13. At the same time, the setting of the housing 1 can realize the protection of the components in the air duct 11 to avoid damage caused by exposure, which is conducive to extending the service life of the air treatment device 100 and has a better appearance effect.

[0052] The pulse lamp module 2 and the plasma module 3 are both arranged in the air duct 11. The pulse lamp module 2 is used to emit pulse light into the air duct 11, and the plasma module 3 is used to generate plasma in the air duct 11, so as to kill the bacteria in the air duct 11 by pulse light and plasma, so that the airflow entering the air duct 11 from the air inlet 12 is killed and sterilized by the pulse lamp module 2 and the plasma module and then blown to the space where the air treatment device 100 is located through the air outlet 13, thereby improving the cleanliness of the air and improving the air quality of the space where the air treatment device 100 is located.

[0053] Specifically, the pulse lamp module 2 uses an inert gas lamp (such as a xenon lamp) to emit pulsed light from ultraviolet to infrared regions, and the spectrum of the pulsed light is similar to the strong pulse flash of the solar spectrum, so the pulsed light can kill microorganisms on solid surfaces, in liquids and gases. Specifically, the main band of the pulsed light emitted by the pulse lamp module 2 is the ultraviolet band, which uses photochemical reactions to form thymine dimers, causing damage to bacterial DNA, leading to cell death or spore passivation. At the same time, the visible light and infrared light output by the pulse lamp module 2 can also be combined with high-energy pulsed strong light to kill microorganisms, that is, the flash thermal effect is used to cause the passivation of enzymes and other cell components, and the pulse effect is used to damage the cell wall and other cell components, resulting in bacterial death.

[0054] The plasma module 3 discharges to ionize the air to generate plasma. The plasma is mainly composed of electrons, positive ions, negative ions, active free radicals, etc. These components have strong physical and chemical activity, thereby quickly degrading toxic and harmful gases and living viruses, bacteria, etc., achieving efficient disinfection, sterilization, deodorization, smoke elimination, and dust removal, and no toxic and harmful substances are produced. Specifically, under the action of the asymmetric plasma electric field formed by high-voltage and high-frequency pulse discharge, the plasma module 3 causes a large number of plasmas in the air to collide step by step, thereby generating an electrochemical reaction, and then hits the virus near the electric field, and kills the virus through high-speed breakdown of the ion group. The charged particles hit the virus at a speed of 2000 meters per second, and the etching and breakdown effects generated by high-kinetic energy electrons and particles are used to make the images of the virus particles after the plasma collision appear to be riddled with holes, and the virus killing effect is good. And negative ions are captured by oxygen to generate negative oxygen ions, and the excess negative oxygen ions generated quickly oxidize the virus: a variety of highly active free radicals kill the virus, and the plasma excites a large number of active oxygen ions, high-energy free radicals and other components, thereby destroying the virus's envelope, and reacting with bacteria, spores, molds and nucleic acid substances in viruses to cause the denaturation and death of various viruses. At the same time, what flows in the space where the plasma module 3 is located is not molecules but ion wind, that is, the molecules are ionized by pulsed high voltage and present an ionic state, and there are positively charged ions and negatively charged ions. Therefore, when the surface of the object is negatively charged, it will attract the positive charge in the airflow, and when the surface of the object is positively charged, it will attract the negative charge in the airflow, so that the static electricity on the surface of the object is neutralized, achieving the effect of eliminating static electricity and dust removal.

[0055] Thus, the pulse light module 2 emits pulse light into the air duct 11, thereby killing bacteria in the air duct 11 through the pulse light, so that the airflow entering the air duct 11 from the air inlet 12 is killed and sterilized by the pulse light module 2 and then blown to the space where the air treatment device 100 is located through the air outlet 13, and the pulse light module 2 has high energy conversion efficiency and does not need to be preheated when used, meeting the user's requirement to turn it on at any time. At the same time, plasma is generated in the air duct 11 through the plasma module 3, so that viruses, bacteria, etc. in the air duct 11 are killed by the plasma, and the static electricity with positive or negative charges on the surface of the object is neutralized by the plasma, thereby achieving dust removal and purification of the air duct 11, so that the airflow entering the air duct 11 from the air inlet 12 is killed, sterilized and dust-removed by the plasma sub-module and then blown to the space where the air treatment device 100 is located through the air outlet 13.

[0056] Therefore, the pulse lamp module 2 and the plasma module 3 are both arranged in the air duct 11, so that the air flow entering the air duct 11 from the air inlet 12 is blown toward the space where the air treatment device 100 is located through the air outlet 13 after being sterilized and purified by the pulse lamp module 2 and sterilized and dust-removed by the plasma module, thereby realizing that the air treatment device 100 has the dual disinfection and sterilization functions of surface sterilization by the pulse lamp module 2 and space sterilization by the plasma module 3, so as to achieve efficient disinfection and sterilization effect, thereby effectively improving the cleanliness of the air and improving the air quality of the space where the air treatment device 100 is located.

[0057] When the air treatment device 100 is turned off and the sterilization mode is turned on, the pulse lamp module 2 and the plasma module 3 run at the same time, or one of the pulse lamp module 2 and the plasma module 3 runs; when the air treatment device 100 is turned on and the sterilization mode is turned on, the pulse lamp module 2 and the plasma module 3 run at the same time, or one of the pulse lamp module 2 and the plasma module 3 runs, so that the air treatment device 100 has different sterilization modes to meet the different needs of users.

[0058] For example, when the air treatment device 100 is turned on and the sterilization mode is turned on, plasma is generated in the air duct 11 through the plasma module 3, so that the viruses, bacteria, etc. in the air duct 11 are killed by the plasma, and the static electricity with positive or negative charges on the surface of the object is neutralized by the plasma, so as to achieve dust removal and purification of the air duct 11, so that the airflow entering the air duct 11 from the air inlet 12 is sterilized and dust-purified by the plasma submodule and then blown to the space where the air treatment device 100 is located through the air outlet 13. And when the air treatment device 100 is turned off and the sterilization mode is turned on, pulse light is emitted into the air duct 11 through the pulse lamp module 2, so that the bacteria in the air duct 11 are killed by the pulse light, and a specific sterilization mode of the air treatment device 100 is achieved.

[0059] It should be noted that the air treatment device 100 of the present application can be applied to an air conditioner, which includes a wind wheel 5, which is arranged in the air duct 11. The wind wheel 5 is used to drive the airflow from the air inlet 12 to the air outlet 13. In the process of the wind wheel 5 driving the airflow to flow in the air duct 11, the airflow is sterilized and sterilized by the pulse lamp module 2 and the plasma module and then flows to the room through the air outlet 13. Among them, the air conditioner can be an integrated machine or a split machine. For an integrated machine, the air conditioner can be a window machine or a mobile air conditioner. For a split machine, the air conditioner can be a wall-mounted machine, a cabinet machine, a duct machine or a ceiling machine, etc. The wall-mounted machine can be a wall-mounted machine or a ceiling-mounted indoor machine.

[0060] According to the air treatment device 100 of the embodiment of the present invention, the shell 1 has an air duct 11 and an air inlet 12 and an air outlet 13 connected to the air duct 11. The shell 1 is arranged in the air duct 11 through a pulse lamp module 2. The pulse lamp module 2 is used to emit pulse light into the air duct 11, so as to kill the bacteria in the air duct 11 through the pulse light, and generate plasma in the air duct 11 through the plasma module 3, so as to kill the viruses, bacteria, etc. in the air duct 11 through the plasma, and the static electricity with positive or negative charges on the surface of the object is neutralized by the plasma, so as to realize dust removal and purification of the air duct 11, so that the airflow entering the air duct 11 from the air inlet 12 is sterilized and sterilized by the pulse lamp module 2 and sterilized and dust-removed and purified by the plasma module, and then blown to the space where the air treatment device 100 is located through the air outlet 13, so as to realize that the air treatment device 100 has a dual disinfection and sterilization function, so as to achieve a high-efficiency disinfection and sterilization effect, thereby effectively improving the cleanliness of the air and improving the air quality of the space where the air treatment device 100 is located.

[0061] In some embodiments of the present invention, Figure 5-Figure 11 As shown, the pulse lamp module 2 includes a first base 21 and a pulse lamp 22. The first base 21 is arranged on the housing 1, and the pulse lamp 22 is arranged on the first base 21. The pulse lamp 22 is used to emit pulse light into the air duct 11. Therefore, the pulse lamp module 2 is arranged in the air duct 11 through the first base 21, so that the pulse lamp 22 emits pulse light into the air duct 11 to kill bacteria in the air duct 11.

[0062] Further, the first base 21 includes a first base 21 body and a first connecting portion that are connected to each other, the first base 21 body has a mounting groove for accommodating the pulse lamp 22, and the first connecting portion has a first fixing portion 212 connected to the housing 1, thereby, the pulse lamp 22 is arranged on the first base 21 through the mounting groove, and the first base 21 is arranged on the housing 1 through the first fixing portion 212, so that the pulse lamp module 2 is arranged in the air duct 11 and the pulse lamp 22 is used to emit pulse light into the air duct 11. It should be noted that the structure of the first fixing portion 212 is not limited here, the first fixing portion 212 can be a first fixing hole, and the first connecting portion is connected to the housing 1 by penetrating the first fixing hole with a fastener, and the first fixing portion 212 can also be a first protrusion, and the housing 1 has a first groove, and the first connecting portion is detachably connected to the housing 1 through the cooperation of the first protrusion and the first groove.

[0063] It should be noted that the position where the first base 21 is arranged on the shell 1 is not limited here, as long as the pulse lamp module 2 is arranged in the air duct 11. For example, when the air treatment device 100 is applied to an air conditioner, the air conditioner includes a wind wheel 5, and the first base 21 is arranged on one of the two opposite side walls of the shell 1 along the axial direction of the wind wheel 5, or the first base 21 is arranged on the opposite side wall of the shell 1 perpendicular to the axial direction of the wind wheel 5. In a specific embodiment of the present invention, the first base 21 is arranged on one of the two opposite side walls of the shell 1 along the axial direction of the wind wheel 5, and the first base 21 extends along the axial direction of the wind wheel 5, so that the pulse lamp 22 extends along the axial direction of the wind wheel 5. Thus, the irradiation area of ​​the pulse light is increased by such an arrangement, thereby increasing the range of sterilization and further improving the air quality.

[0064] In some embodiments of the present invention, Figure 5-Figure 11 As shown, the pulse lamp module 2 also includes a first refractor 23. The first refractor 23 is connected to the first base 21, the pulse lamp 22 is located between the first base 21 and the first refractor 23, and the first refractor 23 is covered outside the pulse lamp 22. Therefore, through the refraction effect of the first refractor 23, the pulse light emitted by the pulse lamp 22 can be refracted to an area where the pulse light cannot reach directly, thereby expanding the sterilization area of ​​the pulse lamp module 2, avoiding the problem that the pulse light cannot be irradiated to the designated sterilization area due to the blocking of the irradiation path, reducing the energy loss of the pulse light, and making the pulse light more concentratedly irradiate the designated sterilization area, thereby improving the utilization rate of the pulse light and the sterilization effect of the pulse lamp module 2. At the same time, the first refractor 23 plays a role in protecting the pulse lamp 22 to a certain extent, thereby improving the reliability of the air treatment device 100.

[0065] Furthermore, the first refractor 23 includes any one of a prism and a lens. Specifically, the prism includes a triangular prism, a quadrangular prism or a prism of any other shape; the lens includes at least a convex lens and a concave lens. In a specific embodiment of the present invention, Figure 3 As shown, when the air handling device 100 is applied to an air conditioner, it also includes a heat exchanger 6 disposed in the air duct 11. Along the air flow direction, the pulse lamp module 2 is located downstream of the heat exchanger 6. Through the refraction of the first refractor 23, the pulse light emitted by the pulse lamp 22 is not only refracted into the air duct 11, but also directly refracted onto the heat exchanger 6, thereby achieving sterilization of the heat exchanger 6 and further improving the sterilization effect of the pulse lamp module 2. At the same time, by setting the first refractor 23 as a prism, a certain water guiding and water-draining function is generated for the condensed water generated by the heat exchanger 6, so that the condensed water generated by the heat exchanger 6 flows along the outer wall of the prism to the water receiving tray located at the lower side of the heat exchanger 6 for collecting the condensed water, and the water accumulation on the first refractor 23 is minimized to ensure the refraction effect of the first refractor 23 on the pulse light and the sterilization effect of the pulse lamp module 2.

[0066] Furthermore, since low-borosilicate glass has the advantages of being resistant to high temperatures above 400°C, explosion-proof, and resistant to temperature differences of 120°C, the first refractor 23 is made of low-borosilicate glass, which can expand the sterilization area of ​​the pulse lamp module 2 while improving the reliability of the pulse lamp module 2.

[0067] In some embodiments of the present invention, Figure 6 , Figure 7 and Fig. 9 As shown, the first base 21 has a support plate 213 on one side facing the pulse lamp 22, and one end of the first refractor 23 close to the pulse lamp 22 is embedded in the support plate 213. Thus, the first refractor 23 is fixed by the support plate 213, so as to avoid displacement of the first refractor 23 during operation or transportation of the air treatment device 100, further protect the pulse lamp 22, and improve the overall reliability.

[0068] In some embodiments of the present invention, Figure 5 and Figure 8 As shown, the pulse lamp module 2 also includes two protective covers 25. The two protective covers 25 and the first refractor 23 are located on the same side of the first base 21 and are connected to the first base 21. Along the length direction of the first base 21, the first refractor 23 is located between the two protective covers 25, and the first refractor 23 is respectively connected to the two protective covers 25. It can be understood that since the first refractor 23 is more fragile than the protective cover 25, the first refractor 23 is further fixed by the two protective covers 25, and the displacement of the first refractor 23 during the operation or transportation of the air treatment device 100 is further avoided. The protective cover 25 plays a certain protective role on the pulse lamp 22, and the overall reliability is further improved.

[0069] In some embodiments of the present invention, Figure 12-Figure 17 As shown, the position on the first base 21 opposite to the pulse lamp 22 is provided with a light-transmitting hole 211, and the pulse lamp module 2 further includes a second refractor 24. The second refractor 24 is located on the side of the first base 21 away from the pulse lamp 22 and is connected to the first base 21, and the second refractor 24 is covered at the light-transmitting hole 211. As a result, the pulse light emitted by the pulse lamp 22 is projected onto the second refractor 24 through the light-transmitting hole 211, and the pulse light emitted by the pulse lamp 22 can be refracted to a larger area through the refraction effect of the second refractor 24, further expanding the sterilization area of ​​the pulse lamp module 2, further avoiding the problem that the pulse light cannot be irradiated to the designated sterilization area due to the blocking of the irradiation path, thereby further reducing the energy loss of the pulse light, and improving the utilization rate of the pulse light and the sterilization effect of the pulse lamp module 2.

[0070] Furthermore, the second refractor 24 includes any one of a prism and a lens. Specifically, the prism includes a triangular prism, a quadrangular prism or a prism of any other shape; the lens includes at least a convex lens and a concave lens. In a specific embodiment of the present invention, Figure 3 As shown, when the air handling device 100 is applied to an air conditioner, it also includes a heat exchanger 6 disposed in the air duct 11. Along the air flow direction, the pulse lamp module 2 is located downstream of the heat exchanger 6. Through the refraction of the second refractor 24, the pulse light emitted by the pulse lamp 22 is not only refracted into the air duct 11, but also directly refracted onto the heat exchanger 6, thereby achieving sterilization of the heat exchanger 6 and further improving the sterilization effect of the pulse lamp module 2. At the same time, by setting the second refractor 24 as a prism, a certain water guiding and water-draining function is generated for the condensed water generated by the heat exchanger 6, so that the condensed water generated by the heat exchanger 6 flows along the outer wall of the prism to the water receiving tray, and the water accumulation on the second refractor 24 is minimized, so as to ensure the refraction effect of the second refractor 24 on the pulse light and the sterilization effect of the pulse lamp module 2.

[0071] Furthermore, since low-borosilicate glass has the advantages of being resistant to high temperatures above 400°C, explosion-proof, and resistant to temperature differences of 120°C, the second refractor 24 is made of low-borosilicate glass, which can expand the sterilization area of ​​the pulse lamp module 2 while improving the reliability of the pulse lamp module 2.

[0072] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the plasma module 3 includes a second base 31 and a plasma emission component 32. The second base 31 is arranged on the housing 1, and the plasma emission component 32 is arranged on the second base 31, and is used to generate plasma in the air duct 11. Therefore, the plasma module 3 is arranged in the air duct 11 through the second base 31, so that the plasma emission component 32 generates plasma in the air duct 11 to kill bacteria in the air duct 11.

[0073] Further, the second base 31 includes a second fixing portion connected to the housing 1, whereby the second base 31 is arranged on the housing 1 through the second fixing portion, so that the plasma module 3 is arranged in the air duct 11 and the plasma emission assembly 32 generates plasma in the air duct 11. It should be noted that the structure of the second fixing portion is not limited here, and the second fixing portion can be a second fixing hole, and the second connection portion is connected to the housing 1 by penetrating the second fixing hole with a fastener, and the second fixing portion can also be a second protrusion, and the housing 1 has a second groove, and the second connection portion is detachably connected to the housing 1 through the cooperation of the second protrusion and the second groove.

[0074] It should be noted that the position where the second base 31 is arranged on the housing 1 is not limited here, as long as the plasma module is arranged in the air duct 11. For example, when the air treatment device 100 is applied to an air conditioner, the air conditioner includes a wind wheel 5, and the second base 31 is arranged on one of the two opposite side walls of the housing 1 along the axial direction of the wind wheel 5, or the second base 31 is arranged on the opposite side wall of the housing 1 perpendicular to the axial direction of the wind wheel 5.

[0075] Meanwhile, the positional relationship between the first base 21 and the second base 31 is not limited here, as long as the plasma module and the pulse lamp module 2 are both arranged in the air duct 11. For example, the first base 21 and the second base 31 are respectively connected to the housing 1, the first base 21 includes a first fixing portion 212 connected to the housing 1, and the second base 31 includes a second fixing portion connected to the housing 1, so that the plasma module and the pulse lamp module 2 are both arranged in the air duct 11; or, the first base 21 includes a first fixing portion 212 connected to the housing 1, and the first base 21 and the second base 31 are connected, so that the plasma module and the pulse lamp module 2 are both arranged in the air duct 11.

[0076] Furthermore, if Figure 6 and Figure 7 As shown, the plasma emission assembly 32 includes two electrode plates 321 and a discharge needle 322, and the discharge needle 322 is located between the two electrode plates 321. The electrode polarities of the two electrode plates 321 and the discharge needle 322 are opposite. Therefore, by passing positive electricity to one of the two electrode plates 321 and the discharge needle 322 and passing negative electricity to the other, an asymmetric plasma electric field is formed between the two electrode plates 321 and the discharge needle 322, so that a large amount of plasma in the air collides step by step, generating an electrochemical reaction, and rapidly degrading toxic and harmful gases and living viruses, bacteria, etc., so as to efficiently kill viruses, sterilize, remove odors, eliminate smoke, and remove dust, and no toxic and harmful substances are generated, thereby achieving sterilization of the air duct 11 by the plasma emitted by the plasma module 3.

[0077] Specifically, the two electrode plates 321 are positively charged, and the discharge needle 322 is negatively charged. The charged bacteria are easily attracted to the two electrode plates 321, and the positive ions gather in large quantities on the bacterial cell membrane. As the concentration of positive ions increases, the potential difference on the cell membrane gradually increases. When the potential difference reaches a certain value, the cell membrane will be broken down, resulting in the destruction of the electrolyte in the cell, thereby exterminating the bacteria in the air duct 11. At the same time, the discharge needle 322 generates negative ions twice the number of positive ions, and the negative ions and positive ions are neutralized, and high energy is released instantly to destroy the bacterial structure. The remaining negative ions are captured by oxygen to generate negative oxygen ions. Since negative oxygen ions have strong oxidizing properties, they can oxidize the nucleic acid and protein structure in bacteria, and negative oxygen ions can also react with odor molecules such as formaldehyde to generate harmless and odorless components such as water. Negative ions are vitamins in the air, which can refresh the air and improve human immunity. In addition, when the air treatment device 100 is used in an air conditioner, excess negative ions are adsorbed by the fins of the heat exchanger 6, thereby adsorbing some positively charged dust on the outer surface of the heat exchanger 6, and the heat exchanger 6 is cleaned through the self-cleaning mode of the air conditioner, so that the dust adsorbed on the outer surface of the heat exchanger 6 is sterilized through self-cleaning technologies such as frosting, defrosting and high-temperature baking, and then discharged to the air conditioner with condensed water, thereby further purifying and removing dust from the air duct 11.

[0078] In some embodiments of the present invention, Figure 5 As shown, the plasma module 3 further includes a protective cover 33. The protective cover 33 is disposed on the second base 31 and connected to the second base 31, and the plasma emission assembly 32 is located between the second base 31 and the protective cover 33. The protective cover 33 has an emission hole 331. Thus, the plasma generated by the plasma module 3 is emitted through the emission hole 331 of the protective cover 33, and the protective cover 33 plays a certain protective role on the plasma emission assembly 32, thereby improving the reliability of the plasma module.

[0079] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, the air treatment device 100 also includes a power supply device 4. The power supply device 4 is arranged on the housing 1, and is electrically connected to the pulse lamp module 2 and the plasma module 3, and is used to supply power to the pulse lamp module 2 and the plasma module 3. Thus, through such a setting, the pulse lamp module and the plasma module 3 are located in the air duct 11, and the pulse lamp module 2 is supplied with power through the power supply device 4, so that the pulse lamp module 2 emits pulse light into the air duct 11, thereby killing bacteria in the air duct 11 through the pulse light, and the plasma module 3 is supplied with power through the power supply device 4, so that the plasma module 3 generates plasma in the air duct 11, thereby killing bacteria in the air duct 11 and purifying and removing dust through the pulse light.

[0080] In some embodiments of the present invention, Figure 6 As shown, the housing of the power supply device 4 is an integral part with the first base 21 of the pulse lamp module 2 and the second base 31 of the plasma module 3. It can be understood that since the power supply device 4 is arranged on the housing 1, and the housing is an integral part with the first base 21 and the second base 31, thus, through such an arrangement, the first base 21 and the second base 31 are indirectly arranged on the housing 1 through the housing, so that the pulse lamp module 2 and the plasma module 3 are both arranged in the air duct 11. At the same time, through such an arrangement, the integration of the pulse lamp module 2 and the plasma module 3 is realized, and the area of ​​the air duct 11 occupied by the pulse lamp module 2 and the plasma module 3 is reduced.

[0081] Furthermore, the power supply device 4 also includes a first wire 41, a second wire and a third wire. The pulse lamp 22 is electrically connected to the power supply device 4 through the first wire 41, the two electrode plates 321 are electrically connected to the power supply device 4 through the second wire, and the discharge needle 322 is electrically connected to the power supply device 4 through the third wire.

[0082] It should be noted that the position where the housing is disposed on the housing 1 is not limited, as long as the pulse lamp module 2 and the plasma module 3 are both disposed in the air duct 11. For example, when the air treatment device 100 is applied to an air conditioner, the air conditioner includes a wind wheel 5, and the housing is disposed on one of the two opposite side walls of the housing 1 along the axial direction of the wind wheel 5, or the housing is disposed on the opposite side wall of the housing 1 perpendicular to the axial direction of the wind wheel 5.

[0083] Meanwhile, the power supply device 4 can be located in the air duct 11 or outside the air duct 11, as long as the power supply device 4 is arranged on the housing 1 and the pulse lamp module 2 and the plasma module 3 are arranged in the air duct 11. For example, the housing is arranged on one of the two opposite side walls of the housing 1 along the axial direction of the wind wheel 5, and the power supply device 4, the pulse lamp module 2 and the plasma module 3 are all arranged in the air duct 11, or the housing is arranged on one of the two opposite side walls of the housing 1 along the axial direction of the wind wheel 5, the power supply device 4 is located on the side of the side wall connected to the housing away from the air duct 11, and the pulse lamp module 2 and the plasma module 3 are arranged in the air duct 11. Different layout modes of the power supply device 4 can be satisfied.

[0084] In a specific embodiment of the present invention, Figure 6As shown, the shell of the power supply device 4 is an integrated part with the first base 21 of the pulse lamp module 2 and the second base 31 of the plasma module 3. The first base 21 is located between the shell and the second base 31. The shell is arranged on one of the two side walls of the shell 1 opposite to each other in the axial direction of the wind wheel 5. The first base 21 has a first fixing portion 212. The side wall connected to the shell is located between the shell and the first base 21 and has a through hole for the first base 21 to pass through and an assembly portion matched with the first fixing portion 212. The fastener passes through the first fixing portion 212 and the assembly portion. The first base 21 and the second base 31 are located in the air duct 11. The power supply device 4 is located on the side of the side wall connected to the shell that is away from the air duct 11, thereby realizing that the pulse lamp module 2 and the plasma module 3 are arranged in the air duct 11.

[0085] In some embodiments of the present invention, the power supply device 4 includes a first power supply device 4 and a second power supply device 4, the first power supply device 4 is connected to the pulse lamp module 2, and is used to supply power to the pulse lamp module 2, and the second power supply device 4 is connected to the plasma module 3, and is used to supply power to the plasma module 3. Thus, the first power supply device 4 is provided on the housing 1, and the first power supply device 4 is connected to the pulse lamp module 2, so that the pulse lamp module 2 is indirectly provided on the housing 1, so that the pulse lamp module 2 is located in the air duct 11, and the second power supply device 4 is provided on the housing 1, and the second power supply device 4 is connected to the plasma module 3, so that the plasma module 3 is indirectly provided on the housing 1, so that the plasma is located in the air duct 11.

[0086] Furthermore, the first power supply device 4 can output signals and energy to control the emission frequency of the pulse light in the pulse lamp module 2 to meet different usage requirements; the second power supply device 4 can select a DC high-voltage power supply, a pulse high-voltage power supply or an AC high-voltage power supply and other devices to increase the amount of plasma generated and improve the disinfection effect.

[0087] Furthermore, the first power supply device 4 also includes a first wire 41, and the second power supply device 4 also includes a second wire and a third wire. The pulse lamp 22 is electrically connected to the first power supply device 4 through the first wire 41, the two electrode plates 321 are electrically connected to the second power supply device 4 through the second wire, and the discharge needle 322 is electrically connected to the second power supply device 4 through the third wire.

[0088] In some embodiments of the present invention, the first power supply device 4 and the second power supply device 4 are arranged at intervals, and the pulse lamp module 2 and the plasma module 3 are arranged at intervals. Thus, through such an arrangement, the pulse lamp module 2 and the plasma module 3 are arranged at intervals in the air duct 11, expanding the range of dual sterilization of the pulse lamp module 2 and the plasma module 3, and meeting different needs of users.

[0089] In some embodiments of the present invention, Figure 3 As shown, the air treatment device 100 also includes a wind wheel 5 and a heat exchanger 6. Among them, the wind wheel 5 is arranged in the air duct 11, and is used to drive the air flow from the air inlet 12 to the air outlet 13. The heat exchanger 6 is arranged in the air duct 11. Along the air flow direction, the heat exchanger 6 is located upstream of the wind wheel 5, and the pulse lamp module 2 and the plasma module 3 are both located downstream of the heat exchanger 6. It can be understood that the airflow outside the air treatment device 100 enters the air duct 11 from the air inlet 12 through the wind wheel 5. After the airflow in the air duct 11 exchanges heat with the heat exchanger 6, it is sterilized and sterilized by the pulse lamp module 2 and the plasma module 3 and then blown into the room through the air outlet 13, thereby achieving the effect of adjusting the indoor temperature and meeting the user's use needs.

[0090] Furthermore, the air treatment device 100 further includes an electric auxiliary heating component 7, which is arranged in the air duct 11, and along the air flow direction, the electric auxiliary heating component 7 is located upstream of the pulse lamp module 2 and the plasma module 3. Therefore, when the air treatment device 100 is in the heating mode, the airflow entering the air duct 11 from the air inlet 12 is first heat-exchanged by the heat exchanger 6, and then the airflow is released into the air through the electric auxiliary heating component 7 to further increase the temperature of the airflow, and then the airflow is sterilized and sterilized by the pulse lamp module 2 and the plasma module 3 and then blown into the room through the air outlet 13, thereby realizing the indoor heating of the air treatment device 100, and the airflow blown into the room has high cleanliness, thereby improving the indoor air quality.

[0091] At the same time, through the pulse lamp module 2, the first refraction mirror 23 is covered on the pulse lamp 22, and through the refraction effect of the first refraction mirror 23, the pulse light emitted by the pulse lamp 22 is not only refracted into the air duct 11, but also directly refracted onto the heat exchanger 6 and the electric auxiliary heating component 7, thereby achieving the sterilization of the heat exchanger 6 and further improving the sterilization effect of the pulse lamp module 2.

[0092] In some embodiments of the present invention, Figure 3 As shown, along the flow direction of the airflow, the pulse lamp module 2 and the plasma module 3 are both located between the heat exchanger 6 and the wind wheel 5. Thus, through such an arrangement, the airflow in the air duct 11 exchanges heat with the heat exchanger 6, and then flows to the wind wheel 5 after being sterilized by the pulse lamp module 2 and the plasma module 3, and flows into the room from the air outlet 13. At the same time, such an arrangement facilitates the integration of the pulse lamp module 2 and the plasma module 3, reducing the space occupied by them in the air duct 11. In addition. By shielding the wind wheel 5, the pulse light emitted by the pulse lamp module 2 is avoided as much as possible from being exposed from the air outlet 13, and the pulse light is avoided as much as possible from directly shining into the user's eyes when the user looks directly at the air outlet 13, thereby improving the safety of the air treatment device 100.

[0093] In some embodiments of the present invention, along the airflow direction, the pulse lamp module 2 is located between the heat exchanger 6 and the wind wheel 5, and the plasma module 3 is located downstream of the wind wheel 5. Thus, through such a setting, the airflow in the air duct 11 exchanges heat with the heat exchanger 6, is sterilized by the pulse lamp module 2, and then is sterilized by the plasma module 3 before flowing into the room from the air outlet 13. At the same time, such a setting expands the dual sterilization area of ​​the pulse lamp module 2 and the plasma module 3, further improving the sterilization effect of the air treatment device 100. In addition, the wind wheel 5 is shielded to avoid the pulse light emitted by the pulse lamp module 2 from being exposed from the air outlet 13 as much as possible, and the pulse light is avoided from directly hitting the user's eyes when the user looks directly at the air outlet 13, thereby improving the safety of the air treatment device 100.
