The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0047] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0048] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0049] According to the air conditioner 100 of the embodiment of the present utility model, Figure 1-Figure 3As shown, the air conditioner 100 includes: a heat exchange duct component 1, an air outlet frame component 2 and a negative ion component 3, an air supply duct 11 is formed in the heat exchange duct component 1, an air outlet duct 21 is formed in the air outlet frame component 2, and the air outlet frame component 2 cooperates with the heat exchange duct component 1 so that the inlet of the air outlet duct 21 is connected to the outlet of the air supply duct 11 to form the duct 101. The negative ion component 3 is installed on the top of the heat exchange duct component 1, and the release end 31 of the negative ion component 3 extends downward to the outlet of the air supply duct 11, so as to release negative ions to the duct 101.

[0050] The heat exchange duct component 1 plays the role of regulating the air flow temperature and providing air flow. The air flow provided by the heat exchange duct component 1 flows out from the air supply duct 11, flows into the air outlet duct 21, and then is guided through the air outlet duct 21 to be sent out from the air conditioner 100 to supply air to the room and regulate the temperature of the indoor space.

[0051] The negative ion component 3 can release negative ions through the release end 31. The negatively charged negative ions undergo electrostatic adsorption with pollutants such as dust in the air, causing the pollutants to condense into larger particles and settle on the ground, thereby purifying the air; the negative ions combine with bacteria in the air to destroy the bacterial structure and have a bactericidal effect.

[0052] By installing the negative ion component 3 on the top of the heat exchange air duct component 1, and the release end 31 of the negative ion component 3 extends downward into the outlet of the air supply air duct 11, the negative ion component 3 releases negative ions to the upper part of the air duct 101. On the one hand, the negative ions can purify and sterilize the air supply of the air conditioner 100, so that the air conditioner 100 provides clean temperature-controlled air to the room; on the other hand, the negative ions are sent to the indoor space with the outlet air to purify and sterilize the indoor air and maintain the indoor environment. And because the negative ions are released at the top of the air duct 101, the negative ions flow a long distance with the air flow, and the negative ions naturally settle from top to bottom with the air flow, the negative ions cover a wide area and are evenly released in the indoor space, which can improve the sterilization and purification effects.

[0053] In addition, by installing the negative ion component 3 inside the air conditioner 100 and arranging it on the heat exchange air duct component 1, compared with arranging the negative ion generator at the air outlet of the air conditioner, the negative ion component 3 can be protected and the integrity of the air conditioner 100 can be improved. Compared with the air outlet frame component 2, the structure of the heat exchange air duct component 1 is relatively simple, and the space for arrangement is larger. Installing the negative ion component 3 on the top of the heat exchange air duct component 1 can effectively utilize the space, which is conducive to the installation and arrangement of the negative ion component 3.

[0054] According to the air conditioner 100 of the embodiment of the utility model, by installing the negative ion component 3 on the top of the heat exchange air duct component 1, the negative ion component 3 releases negative ions to the upper part of the air duct 101, which is conducive to the negative ions being evenly delivered to the indoor space along with the outlet air. The negative ions naturally settle from top to bottom, which can enhance the sterilization and purification effects of the negative ions.

[0055] In some embodiments of the present invention, Figure 1 As shown, the axial direction of the air supply duct 11 is vertically arranged, and a cross-flow fan 15 extending vertically is arranged in the air supply duct 11. The air outlet duct 21 is connected with the air supply duct 11 to form an air duct 101 for supplying air to the room. The air duct 101 has a large size in the vertical direction, which can increase the air supply range of the air conditioner 100 in the vertical direction and the air supply distance of the air conditioner 100, which is conducive to quickly adjusting the room temperature.

[0056] By releasing negative ions at the upper part of the outlet of the vertically extending air supply duct 11, it is more conducive to the natural sedimentation of negative ions from top to bottom, which can enhance the sterilization and purification effect of negative ions.

[0057] In other embodiments of the utility model, the air supply duct 11 extends horizontally, or the air supply duct 11 is arranged obliquely, and the negative ion component 3 is arranged at the top of the heat exchange duct component 1 to release negative ions to the top of the outlet of the air supply duct 11.

[0058] In some embodiments of the present invention, Figure 4-Figure 6 As shown, the negative ion component 3 includes an extension portion 32 , the extension portion 32 is located on a side of the heat exchange air duct component 1 close to the air outlet frame component 2 , and the release end 31 is located at the lower end of the extension portion 32 .

[0059] The extension portion 32 is located between the heat exchange air duct component 1 and the air outlet frame, and the extension portion 32 extends downward to extend the release end 31 into the outlet of the air supply air duct 11 .

[0060] The negative ion component 3 is installed on the top of the heat exchange air duct component 1, and the release end 31 extends from top to bottom into the air duct 101. The installation of the negative ion component 3 does not require drilling holes inside the heat exchange air duct component 1, which can improve the sealing performance of the heat exchange air duct component 1.

[0061] In some embodiments of the present invention, Figure 14-16 As shown, the side of the air outlet frame component 2 facing the heat exchange air duct component 1 has a avoidance portion 22 for avoiding the negative ion component 3, and the avoidance portion 22 is sealed with the heat exchange air duct component 1 through a sealing member.

[0062] The air outlet frame component 2 is connected to the heat exchange air duct component 1 and is located between the heat exchange air duct component 1 and the air outlet frame. The negative ion mounting member 3 is installed on the heat exchange air duct component 1, and the negative ion component 3 protrudes toward the direction of the air outlet frame component 2. Therefore, a side of the air outlet frame component 2 facing the heat exchange air duct component 1 is provided with a avoidance portion 22. The avoidance portion 22 plays a role in avoiding the negative ion component 3, which is conducive to the arrangement of the negative ion component 3 and improves the working stability of the negative ion component 3. The air supply duct 11 formed in the heat exchange air duct component 1 and the air outlet duct 21 formed in the air outlet frame component 2 are connected to form the air duct 101. Therefore, the avoidance portion 22 and the heat exchange air duct 101 are sealed and matched by a sealing member, which can prevent the airflow in the air duct 101 from escaping from the avoidance portion 22, thereby ensuring the air output of the air conditioner 100.

[0063] Optionally, the sealing member is a sealing foam, which contacts the negative ion component 3 . The sealing foam has good sealing performance and can prevent airflow from leaking from the avoidance portion 22 . On the other hand, the sealing foam has strong deformability and will not damage the negative ion component 3 .

[0064] In some embodiments of the present invention, Figure 4-Figure 6 As shown, the negative ion component 3 includes a mounting portion 33, and the mounting portion 33 is engaged with the top of the heat exchange air duct component 1. The mounting portion 33 is located at the upper portion of the negative ion component 3, and the extension portion 32 is located below the mounting portion 33.

[0065] The installation and removal of the negative ion component 3 are facilitated by the snap-fit, which can reduce the difficulty of maintaining the negative ion component 3. Compared with using fasteners such as screws to install the negative ion component 3 on the heat exchange air duct component 1, the installation cost can be saved, and the structure of the heat exchange air duct component 1 will not be changed, and drilling is not required, thereby ensuring the sealing of the heat exchange air duct component 1.

[0066] In some embodiments of the present invention, Figure 4 As shown, a mounting structure 12 extending upward is provided on one side of the top of the heat exchange air duct component 1 close to the air outlet frame component 2 , and the mounting structure 12 is snap-fitted with the mounting portion 33 .

[0067] By providing the upwardly extending mounting structure 12, a stable mounting platform can be provided for the installation of the negative ion component 3, thereby improving the mounting stability of the negative ion component 3. In addition, the upwardly extending mounting structure 12 is provided at a position close to the air outlet frame component 2, so as to facilitate the structural improvement and processing of the heat exchange air duct component 1, and the structure of the air supply air duct 11 in the heat exchange air duct 101 will not be damaged, thereby ensuring the working stability of the heat exchange air duct component 1.

[0068] In some embodiments of the present invention, Figure 4 and Figure 7As shown, the mounting structure 12 is a mounting plate 121 , one side of the mounting plate 121 in the wall thickness direction faces the air outlet frame component 2 , and the thickness direction of the mounting plate 121 is the direction from the heat exchange air duct component 1 to the air outlet frame component 2 .

[0069] like Figure 7 and Figure 8 As shown, the mounting portion 33 includes a first portion 331, a second portion 332 and a third portion 333, the second portion 332 and the first portion 331 are spaced apart along the wall thickness direction of the mounting plate 121, and the upper end of the second portion 332 is connected to the first portion 331 through the third portion 333 to form a bottom-open slot 334 between the first portion 331, the second portion 332 and the third portion 333, the mounting plate 121 is inserted into the slot 334, and the third portion 333 stops at the upper end of the mounting plate 121.

[0070] The mounting portion 33 defines a slot 334 that is open downward, and the negative ion component 3 is mounted on the mounting plate 121 from top to bottom. The mounting portion 33 is inserted into the slot 334, and the third portion 333 abuts against the upper end of the mounting plate 121. The mounting plate 121 can limit the negative ion component 3, and the mounting plate 121 abuts against the third portion 333, which can limit the negative ion component 3 from moving downward.

[0071] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the first portion 331 is located on the side of the mounting plate 121 facing the air outlet frame component 2, and the second portion 332 is located on the side of the mounting plate 121 away from the air outlet frame component 2, as shown in FIG. Figure 5 As shown, the extension portion 32 and the release end 31 are connected below the first portion 331 .

[0072] In other embodiments of the present invention, the first portion 331 is located on a side of the mounting plate 121 away from the air outlet frame component 2, the second portion 332 is located on a side of the mounting plate 121 facing the air outlet frame component 2, and an extension portion 32 and a release end 31 are connected below the second portion 332.

[0073] In some embodiments of the present invention, Figure 8 and Fig.15 As shown, the third portion 333 has downwardly extending flanges 3331 on both sides along the extension direction of the mounting plate 121 , and the lower ends of the flanges 3331 abut against the upper end of the mounting plate 121 .

[0074] The extension direction of the mounting plate 121 is perpendicular to the wall thickness direction of the mounting portion 33, the first portion 331 and the second portion 332 are spaced apart along the wall thickness direction of the mounting plate 121, the third portion 333 is connected between the first portion 331 and the second portion 332, the third portion 333 extends along the wall thickness direction of the mounting plate 121 and the third portion 333 has downwardly extending flanges 3331 on both sides of the direction perpendicular to the wall thickness direction of the mounting plate 121.

[0075] The third part 333 is in contact with the upper end of the mounting plate 121 through the flange 3331. The third part 333 and the mounting plate 121 are in contact through line contact. Compared with the contact of the bottom wall of the third part 333 as a whole with the upper end of the mounting plate 121, the horizontality of the lower end of the flange 3331 is easier to control than the horizontality of the bottom wall of the entire third part 333. By the flange 3331 and the upper end of the mounting plate 121, the spacing difference between the third part 333 and the mounting plate 121 can be reduced, and the shaking caused by the negative ion component 3 being installed on the mounting plate 121 can be reduced, thereby improving the installation stability of the negative ion component 3.

[0076] In some embodiments of the present invention, Figure 8 As shown, the thickness direction of the mounting plate 121 is the front-to-back direction, and the mounting plate 121 extends in the left-to-right direction. The above orientation is described based on the coordinate system of the accompanying drawings, which is only for the convenience of describing and understanding the present invention, and cannot be understood as a limitation of the present invention.

[0077] In some embodiments of the present invention, Figure 9-11 As shown, the upper end of the mounting plate 121 has a protruding portion 1211 protruding upward, and there are two protruding portions 1211 that are respectively stopped at two sides of the third portion 333 along the extension direction of the mounting plate 121 .

[0078] The two protrusions 1211 sandwich the third part 333. The protrusions 1211 can limit the negative ion component 3. The protrusions 1211 are stopped on both sides of the third part 333, which can limit the movement of the negative ion component 3 toward the extension direction of the mounting plate 121, thereby improving the installation stability of the negative ion component 3.

[0079] In some embodiments of the present invention, Figure 8 As shown, the thickness direction of the mounting plate 121 is the front-to-back direction, and the mounting plate 121 extends in the left-right direction. By providing the protrusion 1211, the movement of the negative ion component 3 in the left-right direction is limited, thereby improving the installation stability of the negative ion component 3.

[0080] In some embodiments of the present invention, Fig.10As shown, the height of the side of the protrusion 1211 facing the third part 333 is higher, and the height of the side of the protrusion 1211 away from the third part 333 gradually decreases along the extension direction, and the arc transition between the protrusion 1211 and the top wall of the mounting plate 121 can reduce the stress concentration of the protrusion 1211 and improve the structural stability of the protrusion 1211.

[0081] In some embodiments of the utility model, the third part 333 has downwardly extending flanges 3331 on both sides along the extension direction of the mounting plate 121, and the upper end of the mounting plate 121 has an upwardly protruding protrusion 1211, and there are two protrusions 1211 that are respectively stopped on the outer sides of the flanges 3331 along the extension direction of the mounting plate 121.

[0082] By providing the flange 3331 , the contact area between the third portion 333 and the protrusion 1211 can be increased, and the limiting effect of the protrusion 1211 on the negative ion component 3 can be further enhanced.

[0083] In some embodiments of the present invention, Figure 8 and Fig.10 As shown, the mounting plate 121 has a locking hole 1212 , and the second portion 332 has a locking buckle 3321 protruding toward the first portion 331 . The locking buckle 3321 is locked into the locking hole 1212 to prevent the mounting portion 33 from moving upward relative to the heat exchange air duct component 1 .

[0084] Through the snap fit between the buckle 3321 and the snap hole 1212, on the one hand, the fit stability between the mounting portion 33 and the mounting plate 121 can be improved; on the other hand, the snap hole 1212 can limit the upward movement of the buckle 3321. After the buckle 3321 is snapped into the snap hole 1212, the upper surface of the buckle 3321 abuts against the hole wall of the snap hole 1212. The fit between the snap hole 1212 and the buckle 3321 can limit the upward movement of the negative ion component 3, thereby improving the installation stability of the negative ion component 3.

[0085] The third part 333 stops at the upper end of the mounting plate 121, and the mounting plate 121 can limit the negative ion component 3 and restrict the negative ion component 3 from moving downward; the cooperation between the buckle 3321 and the card hole 1212 can restrict the negative ion component 3 from moving upward, so the movement of the negative ion component 3 in the up and down directions is limited.

[0086] In some embodiments of the present invention, Figure 6 and Figure 8 As shown, the second part 332 has a protrusion 3322 protruding toward the first part 331, the protrusion 3322 is located above the buckle 3321, the protrusion height of the protrusion 3322 is less than the protrusion height of the buckle 3321, and the protrusion 3322 abuts against a side surface of the mounting plate 121 facing away from the first part 331.

[0087] The first part 331 and the second part 332 are disposed on both sides of the thickness direction of the mounting plate 121, so the mounting plate 121 can limit the movement of the negative ion component 3 along the wall thickness direction of the mounting plate 121. By providing a protrusion 3322 protruding toward the first part 331 on the second part 332, the protrusion 3322 abuts against the surface of the mounting plate 121, and the movement of the negative ion component 3 from the second part 332 to the first part 331 in the thickness direction of the mounting plate 121 can be reduced.

[0088] In some embodiments of the present invention, Figure 6 As shown, there are two protrusions 3322, which are arranged at intervals along the extension direction of the mounting plate 121. By arranging the two protrusions 3322 to abut against a surface of the mounting plate 121 facing away from the first portion 331, the arrangement stability of the second portion 332 can be improved.

[0089] In some embodiments of the present invention, Figure 8 As shown, the mounting plate 121 has a first support rib 122 protruding in a direction away from the first portion 331 , the first support rib 122 is located below the card hole 1212 , and the first support rib 122 abuts against a side surface of the second portion 332 facing the mounting plate 121 .

[0090] By providing a first supporting rib 122 protruding toward the second part 332 on the mounting plate 121, the first supporting rib 122 abuts against the surface of the second part 332, which can reduce the movement of the negative ion component 3 from the second part 332 to the first part 331 in the thickness direction of the mounting plate 121.

[0091] In some embodiments of the present invention, Figure 8 and Fig.12 As shown, the second part 332 has a protrusion 3322 protruding toward the first part 331, the protrusion 3322 is located above the buckle 3321, and the protrusion 3322 abuts against the surface of the mounting plate 121; the mounting plate 121 has a first support rib 122 protruding toward the second part 332, the first support rib 122 is located below the buckle 3321, and the first support rib 122 abuts against the surface of the second part 332.

[0092] The upper side of the second part 332 is in contact with the mounting plate 121 through the protrusion 3322, the middle part of the second part 332 is in contact with the clamping hole 1212 through the buckle 3321, and the lower side of the second component is in contact with the mounting plate 121 through the first supporting rib 122. The rotation of the second part 332 relative to the mounting plate 121 can be limited by multi-point limiting, reducing the shaking of the negative ion component 3, and further improving the installation reliability of the negative ion component 3.

[0093] In some embodiments of the present invention, Fig.11 and Fig.12 As shown, the third part 333 includes stop portions 3332 respectively located on both sides of the second part 332 along the extension direction of the mounting plate 121, and the mounting plate 121 has a second support rib 123 protruding in the direction away from the first part 331. There are two second support ribs 123 and they are respectively located on both sides of the second part 332 along the extension direction of the mounting plate 121. The upper end of the second support rib 123 extends to be higher than the mounting plate 121 to stop at the side of the stop portion 3332 away from the first part 331.

[0094] In the extension direction of the mounting plate 121, the size of the third portion 333 is larger than the size of the second portion 332. The portion of the third portion 333 protruding from the second portion 332 in the extension direction of the mounting plate 121 is a stopper 3332. The third portion 333 protrudes from both sides of the second portion 332. There are two stoppers 3332. A second support rib 123 is provided on one side of the mounting plate 121 away from the first portion 331 in the thickness direction. Fig.10 As shown, the second support rib 123 is higher than the mounting plate 121 , and the second support rib 123 is arranged in one-to-one correspondence with the stopper 3332 . After the mounting portion 33 is engaged with the mounting plate 121 , the stopper 3332 stops on the second support rib 123 .

[0095] By providing the second supporting rib 123 and the abutment between the second supporting rib 123 and the abutment portion, the movement of the negative ion component 3 from the first portion 331 to the second portion 332 in the thickness direction of the mounting plate 121 can be reduced.

[0096] The upper side of the second part 332 is abutted against the mounting plate 121 through the protrusion 3322, the middle part of the second part 332 is clamped with the clamping hole 1212 through the buckle 3321, and the lower side of the second part is abutted against the mounting plate 121 through the first supporting rib 122, which can limit the movement of the negative ion component 3 from the second part 332 to the first part 331 in the thickness direction of the mounting plate 121; the stopper 3332 of the third part 333 is abutted against the second supporting rib 123, which can limit the movement of the negative ion component 3 from the first part 331 to the second part 332 in the thickness direction of the mounting plate 121, so the movement of the negative ion component 3 in the thickness direction of the mounting plate 121 is limited. Through the structural design of the mounting plate 121 and the mounting part 33, the multi-directional freedom of the negative ion component 3 can be limited, and the installation stability of the negative ion component 3 can be improved.

[0097] In some embodiments of the present invention, Figure 8As shown, the thickness direction of the mounting plate 121 is the front-to-back direction, and the mounting plate 121 extends in the left-right direction. By designing the mounting plate 121 and the mounting portion 33, the movement of the negative ion component 3 in the up-down direction, the left-right direction, and the front-to-back direction can be restricted, thereby improving the installation stability of the negative ion component 3.

[0098] In some embodiments of the present invention, Figure 8 and Fig.12 As shown, the heat exchange air duct component 1 includes a top plate 13 , the mounting plate 121 extends upward from the top plate 13 , and the lower end of the second supporting rib 123 extends to the top plate 13 .

[0099] The second supporting ribs 123 are connected between the top plate 13 and the mounting plate 121 . The second supporting ribs 123 can also improve the structural strength of the mounting plate 121 , which is beneficial to improving the installation stability of the negative ion component 3 .

[0100] In some embodiments of the present invention, Fig.17 The air conditioner shown, Figure 1 As shown, the heat exchange air duct component 1 includes: an air duct assembly 1a, the air duct assembly 1a includes a crossflow volute 14 and a crossflow fan 15, the crossflow volute 14 defines an air supply duct 11, and the negative ion component 3 is installed on the top of the crossflow volute 14.

[0101] The air duct component 1a is used to provide flowing airflow, and the crossflow fan 15 is a component for generating airflow. The crossflow fan 15 is arranged in the crossflow volute 14, and the crossflow volute 14 defines the air supply duct 11. Therefore, the negative ion component 3 is installed at the top of the crossflow volute 14, so that negative ions can be released to the top of the outlet of the air supply duct 11.

[0102] In some embodiments of the present invention, Figure 1 and Fig.13 As shown, the heat exchange air duct component 1 also includes a heat exchange assembly 1b, which includes a heat exchanger bracket 16 and a heat exchanger 17, and the heat exchanger 17 is installed on the heat exchanger bracket 16. The heat exchanger 17 is used to exchange heat with the airflow flowing through, so that the air conditioner 100 can send out a temperature-controlled airflow. The heat exchanger bracket 16 cooperates with the crossflow volute 14 to define an air inlet duct 102 that is connected to the inlet of the crossflow fan 15 and is located downstream of the heat exchanger 17.

[0103] The crossflow fan 15 in the crossflow volute 14 is started, and the airflow is sucked into the crossflow volute 14. The heat exchange component 1b is located upstream of the airflow direction of the air duct component 1a, that is, the intake airflow first flows through the heat exchange component 1b for heat exchange, and then flows into the crossflow fan 15, and then flows along the air supply duct 11 to the air outlet duct 21 under the action of the crossflow fan 15. The heat exchanger bracket 16 and the crossflow volute 14 jointly define an air inlet duct 102, which is located downstream of the heat exchanger 17 and upstream of the crossflow fan 15. The airflow that has undergone heat exchange in the heat exchanger 17 flows into the air inlet duct 102.

[0104] In some embodiments of the present invention, Figure 1 and Fig.13 As shown, the air conditioner 100 also includes: a pulse sterilization component 4, which is arranged on the top of the heat exchanger bracket 16, and includes a pulse power supply module 41 and a pulse lamp tube 42, the pulse lamp tube 42 is connected to the air inlet duct 102 and is electrically connected to the pulse power supply module 41, and the negative ion component 3 is electrically connected to the pulse power supply module 41.

[0105] The pulse sterilization component 4 includes a pulse power supply module 41 and a pulse lamp 42. The pulse power supply module 41 provides energy to the pulse lamp 42. The pulse lamp 42 can emit high-energy pulse light. For example, the sterilization lamp emits high-intensity ultraviolet pulses. The pulse light irradiates the surface of the microorganism, which can change the substances in the microorganism and inactivate it, killing bacteria and viruses in the air, thereby achieving the purpose of sterilization. In addition, some harmful gases in the air, such as VOC gases, can also be decomposed under the irradiation of the pulse light, thereby achieving the purpose of purifying the air.

[0106] The pulse lamp tube 42 is connected to the air inlet duct 102 , and the pulse lamp tube 42 sterilizes and purifies the air after heat exchange by the heat exchanger 17 , so that the heat exchange airflow flowing into the room is clean, thereby improving the cleanliness of the air supply of the air conditioner 100 .

[0107] It is worth noting that the heat exchanger 17 has a complex structure and is prone to accumulation of pollutants such as dust and bacteria on the heat exchanger 17. Therefore, a pulse lamp 42 is provided to sterilize and purify the airflow of the air inlet duct 102, thereby maintaining the cleanliness of the crossflow fan 15 and improving the cleanliness of the heat exchange airflow of the air conditioner 100. Compared with providing a pulse lamp 42 at the air inlet of the air conditioner 100 to sterilize and purify the airflow before it flows into the heat exchanger 17, the arrangement of the pulse lamp 42 in the embodiment of the utility model can improve the cleanliness of the heat exchange airflow.

[0108] In some embodiments of the present application, the pulse power supply module 41 includes a box body and a first circuit board and a second circuit board that are independent of each other and are arranged in the box body. The first circuit board is electrically connected to the pulse lamp tube 42, and the second circuit board is electrically connected to the release end 31 of the negative ion component 3.

[0109] The pulse power supply module 41 not only provides energy for the pulse lamp 42, but is also electrically connected to the negative ion component 3, and also supplies energy to the negative ion component 3. Integrating the power supply modules of the pulse lamp 42 and the negative ion component 3 into one can save the installation space of the pulse power supply module 41 and simplify the installation method.
