[0001] The present invention relates to the technical field of air purification, and in particular to an electric purification device and an air purifier. Background Art

[0002] With improved living standards and heightened health awareness, people are increasingly interested in various health-related devices. For example, air purifiers have gradually become a necessity in recent years. Traditional air purifiers are primarily categorized by technology: filter-based and electric-based. Both require a motor to generate air flow, drawing outside air into the unit for purification before exhaust. Consequently, traditional air purifiers generate high levels of noise and vibration, and consume high amounts of energy. Summary of the Invention

[0003] Based on this, it is necessary to provide an electric purification device and an air purifier to address the problems of large noise and vibration and high energy consumption of traditional air purifiers.

[0007] A discharge component is at least partially disposed in the discharge channel and spaced apart from an inner sidewall of the discharge channel, so that the discharge component can discharge to the inner sidewall of the discharge channel.

[0008] The technical solution is further described below:

[0009] In one embodiment, the discharge assembly includes a discharge needle having a discharge tip and a mounting base for mounting the discharge needle. The discharge tip is disposed in the discharge channel so that the discharge tip can discharge to the inner wall of the discharge channel.

[0010] In one embodiment, there are at least two discharge needles, and each of the discharge needles is disposed on the mounting seat at intervals around the first direction.

[0012] In one embodiment, the electrical purification device further includes a second conductive body arranged in the discharge channel, the second conductive body is spaced apart from the inner wall of the discharge channel, the diameter of the second conductive body tends to increase along the first direction, and the discharge tip is spaced apart between the inner wall of the discharge channel and the outer wall of the second conductive body, so that the discharge tip can discharge both the inner wall of the discharge channel and the outer wall of the second conductive body.

[0013] In one embodiment, a mounting channel connected to the discharge channel is further provided in the first conductive body, the discharge channel and the mounting channel are arranged along the first direction, the mounting seat is provided in the mounting channel, the mounting seat is connected to the second conductive body, and the discharge needle is insulated from the second conductive body.

[0014] In one embodiment, the second conductive body is provided with a first through hole arranged along the first direction, a second through hole connected to the first through hole is provided in the mounting seat, a mounting hole connected to the second through hole is opened on the outer wall of the mounting seat, and the end of the discharge needle away from the discharge tip passes through the mounting hole and is penetrated into the second through hole.

[0015] In one embodiment, the electric purification device further includes a power supply and a controller electrically connected to the power supply, the controller is electrically connected to the inner wall of the discharge channel and the discharge component, and the controller is used to control the discharge component to discharge the inner wall of the discharge channel.

[0016] In one embodiment, the controller is provided with a high-voltage electrode and a ground electrode, the high-voltage electrode is electrically connected to the discharge assembly, and the ground electrode is electrically connected to the first conductive body.

[0017] In one embodiment, the number of the first conductive bodies and the number of the discharge components are at least two, and an air inlet end and an air outlet end connected to the discharge channel are formed on the first body. The air inlet end, the discharge channel, and the air outlet end are arranged in sequence along the first direction, the air outlet end of the discharge channel is connected to the air inlet end of the adjacent discharge channel, and one discharge component is arranged corresponding to one first conductive body.

[0018] In one embodiment, the electric purification device further includes a flow guide assembly, which is located in the two outermost first conductive bodies, and an air inlet connected to the discharge channel is opened on the outer wall of the air inlet end of one of them, and the flow guide assembly is provided on the air outlet end of the other, and the air inlet, each first conductive body and the flow guide assembly are arranged sequentially along the first direction.

[0019] In one embodiment, the electrical purification device further includes a base, and the first conductive body and the discharge component are both disposed on the base.

At the same time, when the charged pollutant particles move toward the inner wall of the discharge channel, since the diameter of the discharge channel tends to decrease along the first direction, the charged pollutant particles can move in the discharge channel to form an ion wind flowing along the first direction, thereby enabling the air to be inhaled from the end with a larger diameter of the discharge channel under the drive of the ion wind for purification, sterilization and disinfection, and the purified air is discharged from the end with a smaller diameter of the discharge channel, so that the electric purification device can stably and continuously purify the air. In addition, because the diameter of the discharge channel tends to decrease along the first direction, the flow rate of air in the discharge channel along the first direction tends to increase, thereby improving the purification efficiency of the electric purification device. Compared with traditional air purifiers, the electric purification device in this application can circulate and purify air without requiring a motor, resulting in a smaller and quieter electric purification device and greater energy efficiency.

[0032] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1 to 5 As shown, in one embodiment, an electric purification device 10 is provided, comprising a first conductive body 100 and a discharge assembly 200. The first conductive body 100 is provided with a discharge channel 110, and the diameter of the discharge channel 110 is along a first direction (such as Figure 4 The discharge assembly 200 is at least partially disposed in the discharge channel 110 and spaced apart from the inner sidewall of the discharge channel 110 so that the discharge assembly 200 can discharge the inner sidewall of the discharge channel 110 .

[0034] When the electric purification device 10 in the above embodiment is used, the discharge component 200 is energized to form an electric field between the discharge component 200 and the inner wall of the discharge channel 110, so that the discharge component 200 can discharge the inner wall of the discharge channel 110, thereby enabling the pollutant particles (such as dust, etc.) in the discharge channel 110 to be induced to be charged, so that the charged pollutant particles move toward the inner wall of the discharge channel 110 and are adsorbed on the inner wall of the discharge channel 110 under the action of the interaction force between the charges, so as to purify the air in the discharge channel 110. At the same time, when the charged pollutant particles move toward the inner side wall of the discharge channel 110, since the diameter of the discharge channel 110 tends to decrease along the first direction, the charged pollutant particles can move within the discharge channel 110 to form an ion wind flowing along the first direction, thereby allowing the air to be inhaled from the end with a larger diameter of the discharge channel 110 under the drive of the ion wind for purification, sterilization, and the purified air is discharged from the end with a smaller diameter of the discharge channel 110, thereby enabling the electric purification device 10 to purify the air stably and continuously. In addition, since the diameter of the discharge channel 110 tends to decrease along the first direction, the flow rate of the air in the discharge channel 110 along the first direction tends to increase, thereby improving the purification efficiency of the electric purification device 10. Compared with traditional air purifiers, the electric purification device 10 in this application does not require a motor to circulate and purify the air, which reduces the volume and noise of the electric purification device 10 and is more energy-efficient (compared with traditional air purifiers, the electric purification device 10 in this application can reduce energy consumption by about 80%).

[0035] The first direction is the same as the flow direction of the airflow in the discharge channel 110 .

[0036] The electric purification device 10 can be used to purify air, oxygen or other gases, which is not specifically limited here. In this application, the electric purification device 10 is used to purify air as an example for description.

[0037] The first conductive body 100 may be cylindrical, strip-shaped, or in other shapes. The first conductive body 100 may be configured as an integral conductive structure (e.g., the first conductive body 100 may be made of a conductive material such as aluminum or stainless steel), or may be configured as a structure where only the inner sidewall of the discharge channel 110 is conductive (e.g., the inner sidewall of the discharge channel 110 is coated with a conductive coating or film). This is sufficient so that the discharge assembly 200 can discharge the inner sidewall of the discharge channel 110.

[0038] The diameter of the discharge channel 110 tends to decrease along the first direction. The diameter of the discharge channel 110 may be linearly gradually decreased along the first direction, for example, the inner sidewall of the discharge channel 110 is set as a conical surface, etc., or the diameter of the discharge channel 110 tends to decrease nonlinearly along the first direction, for example, the inner sidewall of the discharge channel 110 is set as a curved surface with a certain curvature, etc.

[0039] Optionally, the inner sidewall of the discharge channel 110 is configured as a conical surface, so that air flows more smoothly in the discharge channel 110 .

[0040] The discharge assembly 200 may discharge through a discharge needle, a discharge wire plate, or other discharge structures.

[0041] like Figures 2 to 4 As shown, in one embodiment, the discharge assembly 200 includes a discharge needle 210 having a discharge tip 211 and a mounting base 220 for mounting the discharge needle 210. The discharge tip 211 is disposed within the discharge channel 110 so that the discharge tip 211 can discharge the inner wall of the discharge channel 110. In this way, the discharge tip 211 discharges the inner wall of the discharge channel 110, thereby enhancing the electric field within the discharge channel 110 and improving the purification effect of the electrical purification device 10. Furthermore, the discharge needle 210 is mounted on the mounting base 220, which improves the ease of assembly of the electrical purification device 10.

[0042] The discharge needle 210 is mounted on the mounting base 220 by means of snap connection, plug connection, screw connection or other fixed connection methods.

[0043] The number of the discharge needles 210 can be flexibly adjusted according to actual needs, for example, the number of the discharge needles 210 can be one, four, or eight.

[0044] like Figure 3 and Figure 6 As shown, further, there are at least two discharge needles 210, and each discharge needle 210 is arranged on the mounting base 220 at intervals around the first direction. In this way, each discharge needle 210 can be evenly distributed in the discharge channel 110, so as to ensure that the pollutant particles in the discharge channel 110 can be induced to be charged and adsorbed on the inner wall of the discharge channel 110, thereby improving the purification effect of the electric purification device 10.

[0045] like Figure 6 As shown, optionally, eight discharge needles 210 are provided, and the eight discharge needles 210 are evenly spaced around the first direction and arranged on the mounting base 220. In this way, the purification effect of the electric purification device 10 is better.

[0046] The discharge tip 211 may be arranged parallel to the first direction, perpendicular to the first direction, or at an angle to the first direction.

[0047] like Figure 4 As shown, optionally, the discharge tip 211 is arranged along the first direction. In this way, the discharge uniformity of the discharge tip 211 on the inner wall of the discharge channel 110 is increased, so that the pollutant particles in the discharge channel 110 can be evenly adsorbed on the inner wall of the discharge channel 110, thereby improving the purification effect of the electric purification device 10.

[0048] like Figures 2 to 4 As shown, in one embodiment, the electrical purification device 10 further includes a second conductive body 300 disposed within the discharge channel 110. The second conductive body 300 is spaced apart from the inner sidewall of the discharge channel 110. The diameter of the second conductive body 300 tends to increase along a first direction. The discharge tip 211 is spaced apart between the inner sidewall of the discharge channel 110 and the outer sidewall of the second conductive body 300, so that the discharge tip 211 can discharge both the inner sidewall of the discharge channel 110 and the outer sidewall of the second conductive body 300. In this way, the discharge tip 211 can discharge both the inner sidewall of the discharge channel 110 and the outer sidewall of the second conductive body 300, thereby increasing the area of the electrical purification device 10 used to adsorb pollutant particles and improving the purification efficiency of the electrical purification device 10.

[0049] The second conductive body 300 can be configured as an integral conductive structure (for example, the second conductive body 300 is made of a conductive material such as aluminum or stainless steel), or can be configured as a structure in which only the outer wall of the second conductive body 300 is conductive (for example, the outer wall of the second conductive body 300 is coated with a conductive paint or a conductive film, etc.). It is only necessary to enable the discharge component 200 to discharge the outer wall of the second conductive body 300.

[0050] Among them, the diameter of the second conductive body 300 tends to increase along the first direction. The diameter of the second conductive body 300 can be linearly gradually reduced along the first direction, for example, the outer wall of the second conductive body 300 is set to a conical surface, etc., or the diameter of the second conductive body 300 tends to decrease nonlinearly along the first direction, for example, the outer wall of the second conductive body 300 is set to a curved surface with a certain curvature, etc.

[0051] like Figure 3 and Figure 4As shown, further, a mounting channel 120 is provided within the first conductive body 100 and is connected to the discharge channel 110. The discharge channel 110 and the mounting channel 120 are arranged along a first direction. The mounting seat 220 is disposed within the mounting channel 120. The mounting seat 220 is connected to the second conductive body 300, and the discharge needle 210 and the second conductive body 300 are insulated and matched. In this way, the discharge needle 210 and the second conductive body 300 can both be disposed within the first conductive body 100, so that the discharge needle 210 and the second conductive body 300 are both isolated from the outside, thereby improving the safety and service life of the electric purification device 10. In addition, the discharge needle 210, the mounting seat 220, and the second conductive body 300 can cooperate to form a whole, improving the stability of the electric purification device 10 and the ease of assembly.

[0052] The mounting base 220 and the second conductive body 300 may be connected by snapping, plugging, screwing or other connection methods.

[0053] The discharge needle 210 and the second conductive body 300 are insulated and matched, which means that direct electrical conduction is not possible between the discharge needle 210 and the second conductive body 300 (ie, the mounting base 220 is made of an insulating material).

[0054] The mounting base 220 may be made of plastic, ceramic or other insulating materials.

[0055] like Figure 4 As shown, in one embodiment, the second conductive body 300 is provided with a first through-hole 221 arranged along a first direction, the mounting base 220 is provided with a second through-hole 310 communicating with the first through-hole 221, and the outer wall of the first conductive body 100 is provided with a mounting hole 320 communicating with the second through-hole 310. The end of the discharge needle 210, away from the discharge tip 211, passes through the mounting hole 320 and is inserted into the second through-hole 310. In this way, the first through-hole 221 and the second through-hole 310 cooperate to form a wiring channel for accommodating electrical wires, improving the convenience and safety of connecting the discharge needle 210 to electricity.

[0056] like Figure 2 and Figure 4As shown, in one embodiment, the electric purification device 10 includes a power supply 400 and a controller 500 electrically connected to the power supply 400. The controller 500 is electrically connected to the inner wall of the discharge channel 110 and the discharge assembly 200. The controller 500 is used to control the discharge assembly 200 to discharge the inner wall of the discharge channel 110. In this way, by controlling whether the power supply 400 is electrically connected to the discharge assembly 200 and the inner wall of the discharge channel 110 by the controller 500, the controller 500 can control whether the discharge assembly 200 discharges the inner wall of the discharge channel 110 and the strength of the discharge of the discharge assembly 200 on the inner wall of the discharge channel 110, thereby improving the intelligence and applicability of the electric purification device 10.

[0057] The power supply 400 may be a battery, a storage battery, or other power source. The controller 500 may be a single-chip microcomputer, a programmable logic controller, or other control structure. The controller 500 is electrically connected to the discharge assembly 200 and the inner wall of the discharge channel 110 via wires, conductors, or other conductive structures.

[0058] like Figure 2 As shown, the controller 500 is further provided with a high-voltage electrode and a ground electrode. The high-voltage electrode is electrically connected to the discharge assembly 200, and the ground electrode is electrically connected to the inner wall of the first conductive body 100. In this way, the inner wall of the first conductive body 100 is grounded, so that when the electric purification device 10 is in use, the first conductive body 100 is not charged, thereby improving the safety of the electric purification device 10.

[0059] In other embodiments, the ground electrode can also be electrically connected to the outer wall of the second conductive body 300. In this way, the purification effect of the electrical purification device 10 is improved.

[0060] like Figure 2 As shown, the electrical purification device 10 optionally further includes an electric wire, one end of which is electrically connected to the high-voltage electrode of the controller 500, and the other end of which passes through the first through-hole 221 and is electrically connected to the discharge needle 210 in the second through-hole 310. In this way, the mounting base 220 and the second conductive body 300 can cooperate to separate the discharge tip 211 from the electric wire, thereby preventing interference between the electric wire and the discharge tip 211, thereby improving the reliability and safety of the electrical purification device 10.

[0061] The number of the first conductive body 100, the discharge assembly 200 and the second conductive body 300 can be flexibly adjusted according to actual needs. For example, the number of the first conductive body 100, the discharge assembly 200 and the second conductive body 300 can be one, two or three.

[0062] like Figures 1 to 5As shown, in one embodiment, the number of first conductive bodies 100 and discharge assemblies 200 is at least two. The first conductive body 100 is formed with an air inlet 111 and an air outlet 112 that communicate with the discharge channel 110. The air inlet 111, the discharge channel 110, and the air outlet 112 are arranged sequentially along a first direction. The air outlet 112 of a discharge channel 110 communicates with the air inlet 111 of an adjacent discharge channel 110. One discharge assembly 200 is provided corresponding to one first conductive body 100. In this way, by increasing the number of first conductive bodies 100 and discharge assemblies 200, the electric purification device 10 can purify air multiple times, thereby improving the purification effect of the electric purification device 10. In addition, by providing multiple discharge channels 110, the air within the discharge channel 110 can be accelerated multiple times, thereby increasing the flow rate of the air within the electric purification device 10, thereby improving the purification efficiency of the electric purification device 10.

[0063] Each first conductive body 100 can be electrically connected to the ground electrode of the controller 500 , and each discharge assembly 200 can be electrically connected to the high-voltage electrode of the controller 500 .

[0064] like Figure 2 and Figure 4 As shown, further, there are at least two second conductive bodies 300, one second conductive body 300 corresponding to one discharge channel 110, and the mounting base 220 and the second conductive bodies 300 are arranged sequentially along the first direction. Thus, by increasing the number of second conductive bodies 300, the area of the electric purification device 10 for adsorbing pollutant particles is increased, thereby improving the purification effect of the electric purification device 10. Furthermore, the mounting base 220 and the second conductive bodies 300 are arranged sequentially along the first direction, allowing each discharge assembly 200 and each second conductive body 300 to be assembled into a single unit, thereby improving the stability and assembly convenience of the electric purification device 10.

[0065] Each second conductive body 300 can be electrically connected to the ground electrode of the controller 500 .

[0066] like Figure 4 As shown, optionally, each first through hole 221 is correspondingly connected to each second through hole 310. In this way, the convenience of connecting the discharge needle 210 to electricity is improved.

[0067] like Figure 2 and Figure 4As shown, in one embodiment, the electric purification device 10 further includes a flow guide assembly 700, which is located in the two outermost first conductive bodies 100. An air inlet 130 connected to the discharge channel 110 is provided on the outer wall of the air inlet end 111 of one of the first conductive bodies, and a flow guide assembly 700 is provided on the air outlet end 112 of the other. The air inlet 130, each first conductive body 100, and the flow guide assembly 700 are arranged sequentially along the first direction. In this way, air enters the discharge channel 110 through the air inlet 130 and is purified, and then discharged through the flow guide assembly 700, so that the flow guide assembly 700 can guide the air flowing out of the air outlet 130 to adjust the outflow angle or outflow position of the purified air, thereby improving the applicability of the electric purification device 10. In addition, the flow guide assembly 700 can prevent foreign objects from passing through the air outlet end 112 and moving into the discharge channel 110, thereby improving the safety of the electric purification device 10.

[0068] like Figure 2 and Figure 4 As shown, further, there are at least two air outlets 130, each of which is spaced apart around the first direction on the outer wall of one of the air inlet ends 111. In this way, air can be evenly drawn into the discharge channel 110 through each air inlet 130, making the air distribution in the discharge channel 110 more uniform, thereby improving the air purification effect of the electric purification device 10.

[0069] The number of the air inlets 130 can be flexibly adjusted according to actual needs. For example, the number of the air inlets 130 can be sixteen, twenty, or twenty-four.

[0070] The guide assembly 700 may be a guide plate, a grille or other guide structures.

[0071] The flow guide assembly 700 may be made of non-conductive materials such as plastic or ceramic, thereby improving the reliability and safety of the electric purification device 10.

[0072] like Figure 2 and Figure 4 As shown, optionally, the guide assembly 700 includes a guide grille 720 and a cover 710 having a third through hole 711. The cover 710 is disposed on one side of the first conductive body 100 so that the third through hole 711 is in communication with the discharge channel 110. The guide grille 720 is disposed at an end of the third through hole 711 away from the discharge channel 110. In this way, the purified air in the discharge channel 110 flows out through the third through hole 711 and is guided by the guide grille 720.

[0073] The cover 710 is covered on one side of the first conductive body 100 , and the guide grid 720 is disposed at the end of the third through hole 711 away from the discharge channel 110 , and both can be connected by snapping, plugging, screwing or other fixed connection methods.

[0074] like Figure 2 and Figure 4 As shown, in one embodiment, the power supply 400 and the controller 500 are both disposed in the third through hole 711. In this way, the power supply 400 and the controller 500 do not require additional storage space, thereby reducing the volume of the electric purification device 10 and facilitating storage and transportation of the electric purification device 10.

[0075] like Figure 2 and Figure 4 As shown, further, the power supply 400 is disposed on the controller 500, and the electric purification device 10 further includes a locking member 600, which is used to lock the controller 500 with the inner wall of the third through hole 711. In this way, both the controller 500 and the power supply 400 can be stably and reliably fixed in the third through hole 711, thereby improving the stability and reliability of the electric purification device 10.

[0076] The locking member 600 may be a screw, a latch, or other locking structures. The number of the locking members 600 may be flexibly adjusted according to actual use needs. For example, the number of the locking members 600 may be three, four, or six.

[0077] Optionally, the locking member 600 is configured as a screw, the controller 500 is provided with a through hole, and the inner wall of the third through hole 711 is provided with a threaded hole corresponding to the through hole, and the screw passes through the through hole and is locked with the threaded hole. In this way, the stability and reliability of the fixed connection between the controller 500 and the cover 710 are improved.

[0078] like Figures 2 to 4 As shown, in one embodiment, the electrical purification device 10 further includes a base 800, and the first conductive body 100 and the discharge assembly 200 are both disposed on the base 800. In this way, the base 800, the first conductive body 100, and the discharge assembly 200 can be assembled to form a whole, so that the position of the discharge assembly 200 relative to the first conductive body 100 remains fixed, thereby improving the reliability and stability of the electrical purification device 10.

[0079] The first conductive body 100 and the discharge assembly 200 are both disposed on the base 800 and can be connected by screwing, plugging, clamping or other means.

[0080] The base 800 may be made of non-conductive materials such as plastic or ceramic, thereby improving the reliability and safety of the electric purification device 10.

[0081] In one embodiment, an air purifier is provided, comprising the electric purification device 10 in any one of the above embodiments.

[0082] When the electric purification device 10 in the above embodiment is used, the discharge component 200 is energized to form an electric field between the discharge component 200 and the inner wall of the discharge channel 110, so that the discharge component 200 can discharge the inner wall of the discharge channel 110, thereby enabling the pollutant particles (such as dust, etc.) in the discharge channel 110 to be induced to be charged, so that the charged pollutant particles move toward the inner wall of the discharge channel 110 and are adsorbed on the inner wall of the discharge channel 110 under the action of the interaction force between the charges, so as to purify the air in the discharge channel 110. At the same time, when the charged pollutant particles move toward the inner side wall of the discharge channel 110, since the diameter of the discharge channel 110 tends to decrease along the first direction, the charged pollutant particles can move within the discharge channel 110 to form an ion wind flowing along the first direction, thereby allowing the air to be inhaled from the end with a larger diameter of the discharge channel 110 under the drive of the ion wind for purification, sterilization and disinfection, and the purified air is discharged from the end with a smaller diameter of the discharge channel 110, thereby enabling the electric purification device 10 to purify the air stably and continuously. In addition, since the diameter of the discharge channel 110 tends to decrease along the first direction, the flow rate of the air in the discharge channel 110 along the first direction tends to increase, thereby improving the purification efficiency of the electric purification device 10. Compared with traditional air purifiers, the electric purification device 10 in the present application can circulate and purify the air without a motor, which reduces the volume and noise of the electric purification device 10 and is more energy-efficient.

[0083] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. The term "and / or" used in the present invention includes any and all combinations of one or more of the relevant listed items.

[0084] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0085] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0086] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0087] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0088] It should also be understood that when explaining the connection relationship or positional relationship of elements, even if not explicitly described, the connection relationship and positional relationship should be interpreted as including a range of error, which should be within the acceptable deviation range of the specific value determined by those skilled in the art. For example, "approximately," "approximately," or "substantially" can mean within one or more standard deviations, which is not limited here.

[0089] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
