[0077] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0078] Reference below Figures 1-19 A charging module 100 according to an embodiment of the present invention is described.

[0079] Reference Figure 2-Figure 4 According to the charging module 100 of the first embodiment of the present invention, the charging module 100 includes a mounting frame 1 and a discharge assembly 2. The mounting frame 1 is an insulating member and has a vent 11 formed thereon. The vent 11 is along a first direction (e.g., Figure 1The discharge assembly 2 is mounted on the mounting frame 1 and includes a metal frame 21 and at least one discharge needle 22. The metal frame 21 has at least one opening 211, which extends through the metal frame 21 along a first direction and communicates with the vent 11. The number of discharge needles 22 is the same as the number of openings 211, and the discharge needles 22 correspond one-to-one with the openings 211. The tips of the discharge needles 22 face the corresponding openings 211, and an electric field is formed between the metal frame 21 and the discharge needles 22. When the charging module 100 is energized, a strong electric field is formed between the metal frame 21 and the discharge needles 22. This ionizes the air as it flows through the opening 211, facilitating subsequent collection and processing.

[0080] The mounting frame 1 is formed with a vent 11 extending through the mounting frame 1, facilitating airflow through the mounting frame 1 through the vent 11 and ensuring that airflow can only pass through the mounting frame 1 through the vent 11. A through-hole 211 extends through the metal frame 21 in a first direction, and the through-hole 211 is in communication with the vent 11, allowing airflow to pass through the metal frame 21 and the mounting frame 1 relatively smoothly through the through-hole 211 and the vent 11.

[0081] The tip of the discharge needle 22 is opposite to the corresponding opening 211 and the tip of the discharge needle 22 is spaced apart from the inner wall of the opening 211. For example, the discharge needle 22 extends along the first direction, and the inner wall of the opening 211 can form a metal ring structure on the outer peripheral side of the discharge needle 22 so as to form an electric field between the inner wall of the opening 211 and the discharge needle 22. In this way, when air flows through the opening 211, the ions generated by the electric field can adsorb microorganisms and particulate matter in the air, which is convenient for subsequent purification treatment, thereby achieving an air purification effect.

[0082] Since the metal frame 21 has at least one opening 211, the number of discharge needles 22 is the same as the number of openings 211 and the discharge needles 22 correspond to the openings 211 one-to-one. This ensures that a local strong electric field is formed between the needle tip of the discharge needle 22 in each opening 211 and the metal frame 21, ensuring that the airflow can pass through the electric field when passing through each opening 211, so that the ions can effectively adsorb microorganisms and particulate matter in the air, thereby improving the purification effect of the air.

[0083] In addition, at least one opening 211 is formed on the metal frame 21, and the number of discharge needles 22 is the same as the number of the openings 211, and the discharge needles 22 correspond to the openings 211 one-to-one. In this way, multiple local electric fields can be formed on the same metal frame 21 to effectively improve the air purification effect of the charging module 100, and the overall structure of the charging module 100 can be simplified, the number of components used can be reduced, and it is beneficial to reduce manufacturing costs.

[0084] For example, an electrostatic adsorption module 200 is provided on the downstream side of the charging module 100. When the charging module 100 and the electrostatic adsorption module 200 are powered on, a strong electric field will be generated between the metal frame 21 and the discharge needle 22. Under the action of this electric field, the molecules in the air will be ionized. When the airflow flows through the charging module 100, the ions can adsorb microorganisms and particulate matter in the air. Then, when the airflow flows through the electrostatic adsorption module 200, the electrostatic adsorption module 200 can adsorb microorganisms and particulate matter with ions, thereby achieving the effect of purifying the air.

[0085] The first conductive wire 3 is used to connect the high-voltage transformer 6 and the discharge needle 22. At least a portion of the first conductive wire 3 is located on a side of the mounting frame 1 along the first direction away from the metal frame 21. The first conductive wire 3 provides an electrical connection between the high-voltage transformer 6 and the discharge needle 22, facilitating the high-voltage transformer 6 to transmit high voltage electricity to the discharge needle 22. By having at least a portion of the first conductive wire 3 located on a side of the mounting frame 1 along the first direction away from the metal frame 21, the creepage distance between the first conductive wire 3 and the metal frame 21 can be extended, thereby improving the electrical safety of the charging module 100.

[0086] Among them, at least part of the first conductive line 3 is located on the side of the mounting frame 1 away from the metal frame 21 along the first direction, which may include the following situations: for example, part of the first conductive line 3 may be located on the side of the mounting frame 1 away from the metal frame 21 along the first direction; for another example, the entire first conductive line 3 may be located on the side of the mounting frame 1 away from the metal frame 21 along the first direction.

[0087] For example, if the first conductive wire 3 is located on the side of the mounting frame 1 close to the metal frame 21, the distance between the first conductive wire 3 and the metal frame 21 is too small, which may easily lead to an excessively high electric field strength between the first conductive wire 3 and the metal frame 21. Due to the excessively high electric field strength, the air is broken down and discharge occurs. By locating at least a portion of the first conductive wire 3 on the side of the mounting frame 1 away from the metal frame 21 along the first direction, the creepage distance between the first conductive wire 3 and the metal frame 21 can be effectively extended.

[0088] According to the charging module of the embodiment of the present invention, the discharge needle 22 and the metal frame 21 are both mounted on the mounting frame 1. The discharge needle 22 and the metal frame 21 form an electric field. At least one opening 211 is formed on the metal frame 21. The number of discharge needles 22 is the same as the number of openings 211, and the discharge needles 22 and the openings 211 correspond one-to-one. In this way, multiple local electric fields can be formed on the same metal frame 21 to effectively improve the air purification effect of the charging module 100. The overall structure of the charging module 100 can also be simplified, reducing the number of components used, which is conducive to reducing manufacturing costs. In addition, the first conductive wire 3 can facilitate the electrical connection between the high-voltage coil 6 and the discharge needle 22. Since at least a portion of the first conductive wire 3 is located on the side of the mounting frame 1 away from the metal frame 21 along the first direction, the creepage distance between the first conductive wire 3 and the metal frame 21 can be effectively increased, which is conducive to improving the overall electrical safety of the charging module 100.

[0089] Reference Figure 3 、 Figure 6 and Figure 17 According to some embodiments of the present invention, the metal frame 21 has a first surface, which is located on one side of the metal frame 21 along the first direction. The direction of the first surface is opposite to the direction of the needle tip, and the end point of the needle tip and the first surface are located in the same plane. In this way, the distance between the end point of the needle tip and the inner wall of the through opening 211 of the metal frame 21 can be as small as possible, thereby improving the purification effect.

[0090] Reference Figure 3 、 Figure 6 and Figure 17 According to some embodiments of the present invention, the discharge needle 22 extends along a first direction, and the tip of the discharge needle 22 is directed toward the upstream side of the charging module 100. The tip of the discharge needle 22 can generate a large number of ions. With the tip of the discharge needle 22 directed toward the upstream side of the charging module 100, these ions can better adsorb microorganisms and particulate matter in the air to improve the purification effect.

[0091] It should be explained that the upstream side is relative to the direction of the airflow passing through the charging module 100 .

[0092] Reference Figure 15-17 According to some embodiments of the present invention, the tip of the discharge needle 22 is located on the center line of the corresponding through-hole 211. This can improve the uniformity of the electric field distribution formed between the tip of the discharge needle 22 and the inner wall of the corresponding through-hole 211, and can make the ion distribution in the electric field more uniform, so that the ions can adsorb more microorganisms and particulate matter in the air, thereby improving the air purification effect.

[0093] Reference Figure 10 、 Figure 15 and Figure 16 According to some embodiments of the present invention, the projection of the tip of the discharge needle 22 on the reference plane is the first projection, and the corresponding projection of the opening 211 on the reference plane is the second projection. The first projection is located within the second projection, and the distance w1 between the contour lines of the first projection and the second projection ranges from 15 mm to 25 mm. The reference plane is perpendicular to the first direction. For example, the spacing w1 between the contour lines of the first projection and the second projection can be 15 mm, 18 mm, 20 mm, 23 mm, 25 mm, etc. By ensuring that the spacing w1 between the contour lines of the first projection and the second projection is not less than 15 mm, the number of discharge needles 22 can be reduced within the effective discharge range of the needle tip of the discharge needle 22, which is beneficial to reducing costs, and can also make the electric field distribution more uniform, reduce the unevenness of local discharge, and improve the discharge effect; by ensuring that the spacing w1 between the contour lines of the first projection and the second projection is not greater than 25 mm, it can be ensured that a sufficiently strong electric field is formed between the needle tip of the discharge needle 22 and the inner wall of the through-port 211. The stronger electric field helps to form a higher ion concentration in the through-port 211, so as to have better purification and sterilization effects on the air.

[0094] The distance w1 between the contour lines of the first projection and the second projection is in the range of 15 mm to 25 mm. Within the effective discharge range of the needle tip of the discharge needle 22, the number of discharge needles 22 can be reduced, and the ion concentration formed in the opening 211 can be ensured to be high, so as to have better purification and sterilization effects on the air.

[0095] Reference Figure 10 、 Figure 15 and Figure 16 According to some embodiments of the present invention, the opening 211 is rectangular. Since a plurality of openings 211 are formed on the metal frame 21, the openings 211 are rectangular. While ensuring the structural strength of the metal frame 21, the spacing between adjacent openings 211 can be made smaller, thereby increasing the area of ​​the openings 211, thereby effectively reducing the area of ​​the airflow blocked by the metal frame 21 in the airflow flow section, thereby reducing the resistance of the airflow when flowing through the metal frame 21, and allowing the airflow to flow more smoothly through the openings 211.

[0096] In the description of the present invention, “plurality” means two or more.

[0097] Reference Figure 10 、 Figure 15 and Figure 16According to some embodiments of the present invention, the four corners of the opening 211 are rounded to reduce or avoid ion accumulation. For example, if the four corners of the opening 211 are all right angles, then these areas are prone to electric field concentration, causing ion accumulation.

[0121] Reference Figure 15-17 According to some embodiments of the present invention, there are multiple openings 211 and discharge needles 22, and the multiple openings 211 are distributed on a plane perpendicular to the first direction, which can increase the ventilation area to reduce the area of ​​the airflow blocked by the metal frame 21 on the flow cross section, so that the airflow flows more smoothly through the charging module 100 and ensures that the airflow can be affected by the electric field at multiple positions on the flow cross section.

[0122] Reference Figure 15 and Figure 16 According to some embodiments of the present invention, the plurality of openings 211 are arranged in multiple rows and columns, ensuring that the airflow is affected by the electric field at multiple locations, thereby improving the uniformity and efficiency of ionization.

[0123] Reference Figure 17-Figure 19According to some embodiments of the present invention, the endpoints of the needle tips of the plurality of discharge needles 22 are located in the same plane, which ensures the consistency of discharge and thus improves the purification effect.

[0124] Reference Figure 3 、 Figure 5 and Figure 10 According to some embodiments of the present invention, the number of ventilation openings 11 is the same as the number of through-holes 211 and they correspond one to one. Each through-hole 211 is opposite to and connected to the corresponding ventilation opening 11, which can ensure that the airflow can only flow through these ventilation openings 11 and flow out through the through-holes 211, so as to ensure that the airflow flowing through the charging module 100 can be affected by the electric field at the through-holes 211, and ensure that the gas flowing through the through-holes 211 can pass through the electric field so that impurities such as dust in the air can be adsorbed as charged ions, thereby improving the purification effect.

[0125] Reference Figure 3-Figure 5 According to some embodiments of the present invention, the projection of each opening 211 on the reference plane is located within the projection of the corresponding ventilation opening 11 on the reference plane, and the reference plane is perpendicular to the first direction. In this way, the outer peripheral side of the needle tip of the discharge needle 22 is closer to the inner wall of the opening 211, which can reduce the influence of the insulation of the mounting frame 1 between the needle tip and the inner wall of the opening 211.

[0126] For example, if the inner wall of the vent 11 of the mounting frame 1 is located between the needle tip and the inner wall of the through-port 211, this will increase the creepage distance between the needle tip and the inner wall of the through-port 211, thereby affecting the electric field strength between the needle tip and the through-port 211, thereby affecting the purification effect of the charging module 100. By locating the projection of each through-port 211 on the reference plane within the projection of the corresponding vent 11 on the reference plane, the inner wall of the through-port 211 can be directly surrounded by the needle tip, thereby avoiding this unnecessary increase and improving the purification effect of the charging module 100.

[0127] Reference Figure 3 、 Figure 4 and Figure 13According to some embodiments of the present invention, the mounting frame 1 includes a frame body 16 and cantilever beams 17. Ventilation openings 11 are formed on the frame body 16. The number of cantilever beams 17 is the same as the number of vents 11, and each cantilever beam 17 corresponds to each vent 11. Each cantilever beam 17 is located within a corresponding vent 11. The two ends of the cantilever beam 17 in the longitudinal direction are a fixed end and a free end, respectively. The fixed end is connected to the frame body 16. The number of cantilever beams 17 is the same as the number of discharge needles 22, and each cantilever beam 17 corresponds to each discharge needle 22. Each discharge needle 22 is mounted at the free end of a corresponding cantilever beam 17. The fixed end is connected to the frame body 16. The frame body 16 can support and secure the cantilever beams 17, and the cantilever beams 17 can also support and secure the discharge needles 22. By installing the discharge needle 22 at the free end of the corresponding cantilever beam 17 , the tip of the discharge needle 22 can be located in the corresponding through opening 211 , so that an electric field is formed between the tip of the discharge needle 22 and the inner wall of the through opening 211 .

[0128] Reference Figure 3 、 Figure 4 and Figure 13 According to some embodiments of the present invention, a fixing hole 171 is provided at the free end of the cantilever beam 17, and the discharge needle 22 is passed through the fixing hole 171. The fixing hole 171 can facilitate the discharge needle 22 to pass through it, making the assembly of the discharge needle 22 on the cantilever beam 17 more convenient and making the overall structure of the discharge needle 22 and the cantilever beam 17 compact.

[0129] Reference Figure 11-13 According to some embodiments of the present invention, the free end of the cantilever beam 17 is semicircular, which can reduce the area of ​​airflow blocked on the flow cross section to reduce the resistance of the airflow; and, compared with a rectangle, the free end of the cantilever beam 17 is semicircular, which can avoid ion accumulation due to overly sharp corners.

[0130] Reference Figure 7 、 Figure 11 and Figure 13 According to some embodiments of the present invention, the cantilever beam 17 has a second surface and a third surface arranged opposite to each other along a first direction, wherein, in the direction from the fixed end to the free end, at least a portion of the second surface and / or the third surface extends obliquely toward a direction close to the center plane of the frame body 16, the center plane of the frame body 16 passes through the center of the frame body 16 and the center plane of the frame body 16 is perpendicular to the first direction. By extending at least a portion of the second surface and / or the third surface obliquely toward a direction close to the center plane of the frame body 16 in the direction from the fixed end to the free end, the space occupied by the cantilever beam 17 after deformation along the first direction can be reduced or avoided.

[0131] Among them, at least part of the second surface and / or the third surface extending obliquely toward the direction close to the center plane of the frame body 16 may include the following situations: for example, part of the second surface or the third surface may extend obliquely toward the direction close to the center plane of the frame body 16, or part of the second surface and the third surface may extend obliquely toward the direction close to the center plane of the frame body 16; for another example, the entire second surface or the third surface may extend obliquely toward the direction close to the center plane of the frame body 16, or the entire second surface and the third surface may extend obliquely toward the direction close to the center plane of the frame body 16.

[0132] For example, the cantilever beam 17 may be made of plastic to provide insulation. The free end of the cantilever beam 17 is more easily deformed along the first direction. If the free end of the cantilever beam 17 is deformed toward the side of the mounting frame 1 away from the metal frame 21 along the first direction, the deformed cantilever beam 17 is likely to occupy more external space on the side of the mounting frame 1 away from the metal frame 21 along the first direction. For example, the electrostatic adsorption module 200 is installed on the side of the mounting frame 1 away from the metal frame 21 along the first direction. If the cantilever beam 17 occupies more external space on the side of the mounting frame 1 away from the metal frame 21 along the first direction after deformation, the cantilever beam 17 is likely to interfere with the electrostatic adsorption module 200, making it difficult to assemble the electrostatic adsorption module 200 on the mounting frame 1. By extending at least a portion of the second surface and / or the third surface in an inclined manner toward the direction close to the central plane of the frame body 16 in the direction from the fixed end to the free end, the space occupied by the cantilever beam 17 after deformation in the first direction can be effectively reduced, thereby facilitating the assembly of the electrostatic adsorption module 200 on the mounting frame 1.

Multiple branch lines 33 are led out from the main line 32 . Each branch line 33 is routed along a corresponding cantilever beam 17 and connected to the discharge needle 22 . The cantilever beam 17 can guide the branch lines 33 to be arranged along a set path.

[0134] Moreover, since the mounting frame 1 is an insulating part, the main line body 32 and the plurality of branch line bodies 33 are all located on the side of the mounting frame 1 away from the metal frame 21 along the first direction, which can serve as insulation between the main line body 32 and the branch line body 33 and the metal frame 21, and can increase the creepage distance between the main line body 32 and the branch line body 33 and the metal frame 21, thereby helping to improve the overall electrical safety of the charging module 100.

Because the two discharge needle groups 221 are arranged along the second direction, the presence of at least portions of the main wires 32 of the two first conductive wires 3 at opposite ends of the frame body 16 along the second direction can reduce interference between the main wires 32 of the two first conductive wires 3 and facilitate connection between the main wires 32 and the corresponding discharge needle groups 221. Furthermore, since both first conductive wires 3 are routed along the third direction, connection can be achieved between the main wires 32 and the multiple discharge needles 22 of the corresponding discharge needle groups 221 arranged at intervals along the third direction.

In addition, since the second wire segment 322 is located at one end of the frame body 16 along the third direction and the second wire segment 322 is arranged along the second direction, the connection between the first wire segment 321 and the second wire segment 322 can be realized and the main wire body 32 of one of the first conductive wires 3 can be arranged along the frame body 16.

[0144] Reference Figure 4 、 Figure 5 and Figure 10 According to some embodiments of the present invention, the first conductive wire 3 also includes an extension section 34. One end of the extension section 34 of the two first conductive wires 3 is connected to the corresponding main wire body 32, and the other end of the extension section 34 of the two first conductive wires 3 is connected as a whole through the conductive terminal 31. The connection between the two first conductive wires 3 and the conductive terminal 31 can be achieved through the extension section 34. For example, the charging module 100 includes a first connecting wire, and the first connecting wire connects the conductive terminal 31 and the positive electrode of the high-voltage package 6. In this way, the connection between the first conductive wire 3 and the positive electrode of the high-voltage package 6 can be achieved.

[0145] Reference Figure 2 、 Figure 4 and Figure 11 According to some embodiments of the present invention, a wire hole 161 is formed in the frame body 16, and the extension section 34 extends to the outer periphery of the frame body 16 through the wire hole 161. The wire hole 161 facilitates the passage of the extension section 34, thereby facilitating the assembly of the first conductive wire 3 on the frame body 16 and making the overall structure of the extension section 34 and the frame body 16 more compact.

[0146] Reference Figure 2 、 Figure 4 and Figure 11According to some embodiments of the present invention, insulating ribs 162 are provided on the frame body 16. The insulating ribs 162 and the metal frame 21 are located on the same side of the frame body 16 along the first direction. The insulating ribs 162 are located on the outer periphery of the frame body 16 and between the metal frame 21 and the extension section 34. The insulating ribs 162 can enhance the overall structural strength of the mounting frame 1 to a certain extent. By locating the insulating ribs 162 between the metal frame 21 and the extension section 34, electrical isolation between the metal frame 21 and the extension section 34 can be ensured. Furthermore, by locating the insulating ribs 162 on the outer periphery of the frame body 16, the creepage distance between the metal frame 21 and the extension section 34 can be increased.

[0147] Reference Figure 2 、 Figure 4 and Figure 11 According to some embodiments of the present invention, the cross-section of the insulating rib 162 is L-shaped, which can further extend the creepage distance between the metal frame 21 and the extension section 34. The L-shaped cross-section allows the insulating rib 162 to better fit the outer periphery of the frame body 16, thereby enhancing the stability of the insulating rib 162 on the frame body 16. The cross-section of the insulating rib 162 is L-shaped, which can further extend the contact path between the metal frame 21 and the extension section 34, thereby effectively increasing the creepage distance between the metal frame 21 and the extension section 34, thereby improving the electrical safety of the charging module 100.

[0148] Reference Figure 3 、 Figure 6 and Figure 10 According to some embodiments of the present invention, a high-voltage transformer 6 is included. The high-voltage transformer 6 is mounted on one side of the frame body 16 along the third direction. The main line body 32 is connected to the positive electrode of the high-voltage transformer 6, and the metal frame 21 is connected to the negative electrode of the high-voltage transformer 6. The space of the mounting frame 1 along the third direction is fully utilized to arrange the high-voltage transformer 6, the main line body 32, and the metal frame 21 in an orderly manner. Because each discharge needle group 221 includes a plurality of discharge needles 22 spaced apart along the third direction, the high-voltage transformer 6 is mounted on one side of the frame body 16 along the third direction. This shortens the distance between the high-voltage transformer 6 and the metal frame 21 and the main line body 32 located on opposite sides of the frame body 16 along the first direction. This reduces the length of the first connecting line between the high-voltage transformer 6 and the main line body 32 and the second connecting line 5 between the high-voltage transformer 6 and the metal frame 21, thereby reducing energy transmission losses to a certain extent.

[0149] Reference Figure 4 、 Figure 5 and Figure 11According to some embodiments of the present invention, a deflector plate 7 and a temperature sensing wire 8 are further included. The deflector plate 7 is connected to the outer periphery of the mounting frame 1, and the temperature sensing wire 8 is mounted on the deflector plate 7 and is used to detect the inlet air temperature. The deflector plate 7 can guide the airflow so that the airflow flows along the direction in which the deflector plate 7 extends. By mounting the temperature sensing wire 8 on the deflector plate 7, the inlet air temperature passing through the deflector plate 7 can be detected.

[0150] For example, the air conditioner includes a casing assembly and a purification assembly 1000. The casing assembly is formed with an air inlet. The purification assembly 1000 is arranged inside the casing assembly and close to the air inlet. When the charging module 100 is used for the purification assembly 1000 of the air conditioner, it is installed on the guide plate 7 through the temperature sensing line 8. The temperature sensing line 8 can detect the inlet air temperature. If the inlet air temperature is detected to be low, it means that the indoor temperature is low and condensation may occur. When the inlet air temperature is low, the temperature of the air conditioner can be controlled to increase to reduce the generation of condensation.

[0151] Reference Figure 4 、 Figure 5 and Figure 11 According to some embodiments of the present invention, an air hole 71 is formed on the guide plate 7, and the air hole 71 penetrates the guide plate 7 along a first direction. The temperature sensing line 8 includes a temperature sensing head 81 and a temperature sensing line body 82 connected to the temperature sensing head 81. The temperature sensing head 81 is opposite to the air hole 71. The guide plate 7 is penetrated along the first direction through the air hole 71, and the temperature sensing head 81 is opposite to the air hole 71. The temperature sensing head 81 can be in direct contact with at least part of the incoming air flow, which can improve the accuracy of the detected incoming air temperature.

[0152] Reference Figure 4 、 Figure 5 and Figure 11 According to some embodiments of the present invention, the air holes 71 are multiple and spaced apart along the length direction of the temperature sensing head 81, which can increase the contact area between the temperature sensing head 81 and the airflow, thereby further improving the accuracy of the detected inlet air temperature.

[0153] Reference Figure 4 and Figure 5 According to some embodiments of the present invention, the length direction of each air hole 71 intersects with the length direction of the temperature sensing head 81. In this way, when subjected to external impact or vibration, the temperature sensing head 81 is not likely to fall into the air hole 71, thereby ensuring the overall stability and reliability of the charging module 100.

The first limit buckle 72 cooperates with the temperature sensing head 81 to limit the temperature sensing head 81, and the second limit buckle 73 cooperates with the temperature sensing line 82 to limit the temperature sensing line 82. The first limit buckle 72 can limit the temperature sensing head 81 to ensure that the assembly position of the temperature sensing head 81 on the guide plate 7 is accurate, and can reduce or prevent the temperature sensing head 81 from loosening or moving due to external impact or vibration. The second limit buckle 73 can limit the temperature sensing line 82 to ensure that the temperature sensing line 82 is routed according to the set path, and can reduce or prevent the temperature sensing line 82 from loosening or moving due to external impact or vibration.

[0155] Reference Figure 11-13 According to some embodiments of the present invention, at least some of the retaining buckles have openings in opposite directions, perpendicular to the extension direction of the temperature-sensing cable 8. Having at least some of the retaining buckles open in opposite directions can disperse stress, reduce the force applied to individual retaining buckles, and thereby improve the overall retaining effect on the temperature-sensing cable 8. The retaining buckles have openings perpendicular to the extension direction of the temperature-sensing cable 8, making it easier to insert the temperature-sensing cable 8 through the retaining buckle openings during installation and allowing the temperature-sensing cable 8 to be stably secured within the retaining buckle after installation.

[0156] Among them, the opening directions of at least some of the limiting buckles are opposite, which may include the following situations: for example, the opening directions of some of the limiting buckles are opposite; for another example, the opening directions of all the limiting buckles are opposite.

[0157] Reference Figure 4 、 Figure 5 and Figure 11 According to some embodiments of the present invention, the temperature sensing wire 82 is provided with a retaining ring 821, which is located between the temperature sensing head 81 and the second retaining buckle 73. The retaining ring 821 prevents the temperature sensing wire 82 from being overstretched during installation or use, thereby reducing or avoiding damage to the temperature sensing wire 82. The retaining ring 821 also serves as a reference point, helping the installer to more accurately secure the temperature sensing wire 82 to the deflector 7, ensuring that the temperature sensing wire 82 is correctly positioned.

[0158] Optionally, the guide plate 7 is further provided with a limiting rib 74, which is used to limit the temperature sensing wire 82. The limiting rib 74 can enhance the overall structural strength of the guide plate 7. By limiting the temperature sensing wire 82 with the limiting rib 74, the temperature sensing wire 82 can be more stably fixed on the guide plate 7, reducing or avoiding the temperature sensing wire 82 from detaching from the guide plate 7.
