Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a wiper device and cleaning equipment. Background Art

[0002] With the development of science and technology and social progress, more and more families have begun to use floor cleaning machines instead of traditional mops for cleaning. In order to collect water stains on the floor, a scraper strip is generally provided on the roller brush of the floor scrubber to keep close to the ground, so as to reduce the residual water stains on the ground. The floor scrubber in the prior art has a soft rubber scraper strip on the rear side of the roller brush. When the roller brush moves forward, the scraper strip is turned back under the friction of the ground and scrapes water close to the ground to reduce the residual water stains on the ground. When users mop the floor for small area stains, they tend to push and pull back and forth to clean. For large spaces such as the entire room and living room, the overall trend is to clean backwards, but after pulling back, the roller brush with water wets the ground again, and the residual water stains on the ground are not reduced, resulting in poor cleaning effect. Utility Model Content

[0003] Based on this, it is necessary to provide a wiper device and a cleaning device to address the problem that the roller brush with water wets the ground again after the floor scrubber is pulled back in the prior art, the residual water stains on the ground cannot be reduced, and the cleaning effect is poor.

[0004] The technical solution is as follows:

[0005] In one aspect, a wiper device is provided, which is applied to a cleaning device having a cleaning body, and the wiper device comprises:

[0006] A mounting bracket, the mounting bracket being used to be mounted on the front end of the cleaning body;

[0007] a wiper member, the wiper member being movably engaged with the mounting bracket;

[0008] A driving mechanism is installed on the mounting bracket and is drivingly connected to the wiper element so that the length of the wiper element extending from the bottom of the mounting bracket is adjustable.

[0009] In the wiper device of the above embodiment, when the cleaning body is pushed forward, the driving mechanism drives the wiper element to rise relative to the mounting bracket, so that the length of the wiper element extending from the bottom of the mounting bracket is reduced, the wiper element is away from the ground, and no wiping is achieved. When the cleaning body is pulled back, the driving mechanism drives the wiper element to descend relative to the mounting bracket, so that the length of the wiper element extending from the bottom of the mounting bracket is increased, and the wiper element contacts the ground, ensuring that the wiper element can effectively wipe away the water stains generated when the cleaning body is pulled back, and ensuring the cleaning effect of the cleaning device while satisfying the user's habit of cleaning backwards as a whole.

[0010] The technical solution is further described below:

[0011] In one embodiment, the driving mechanism includes a driving member and a transmission assembly. The driving member is mounted on the mounting bracket and is in transmission connection with the transmission assembly, and the transmission assembly is in transmission connection with the wiper member.

[0012] In one embodiment, the mounting bracket is provided with a mounting hole, and the driving member is mounted in the mounting hole. With such a design, the mounting hole can play a positioning role to ensure that the driving member can be quickly and accurately mounted at a preset position on the mounting bracket, so as to precisely control the length of the wiper member extending from the bottom of the mounting bracket, and improve the reliability of the wiper device.

[0013] In one embodiment, the driving member is provided with a telescopic end, the transmission assembly includes a transmission rope, one end of the transmission rope is connected to the telescopic end, and the other end is connected to the wiper member.

[0014] In one embodiment, the moving direction of the wiper member relative to the mounting bracket is set as a first direction, the telescopic end of the driving member is telescopically arranged along a second direction intersecting with the first direction, the transmission assembly further includes a rolling member, the rolling member is rotatably mounted on the mounting bracket and is located between the telescopic end of the driving member and the wiper member along the first direction, and the transmission rope between the telescopic end and the wiper member is tensioned and wound around the rolling member, so that the transmission rope between the rolling member and the wiper member is tensioned along the first direction instead of the original second direction. With such a design, the driving member can be installed at different positions according to space requirements, improving the adaptability of the wiper device. In addition, the transmission rope between the rolling member and the wiper member is arranged along the first direction, so that the transmission rope exerts a driving force along the first direction on the wiper member, ensuring that the transmission rope can pull the wiper member upward and improving the reliability of the wiper device.

[0015] In one embodiment, the wiper device further includes an elastic member. The elastic member is mounted between the mounting bracket and the wiper member and is used to be compressed when the length of the wiper member extending from the bottom of the mounting bracket decreases, and to rebound and reset when the length of the wiper member extending from the bottom of the mounting bracket increases. With such a design, when the cleaning body is pushed forward, the push-pull electromagnet is energized, the push-pull electromagnet is in a pulling state, the telescopic end is compressed to lift the steel wire, the elastic member is compressed, the wiper member is lifted upward and moves to the lifted position, and the wiper member is away from the ground, so that wipering is not realized. When the cleaning body is pulled backward, the push-pull electromagnet is powered off, the push-pull electromagnet is in a pushing state, the telescopic end extends and restores, the steel wire is lowered, the elastic member rebounds and resets to push the wiper member downward and move to the lowered position, and the wiper member contacts the ground to realize wipering during the backward pulling process, improving the practicability of the wiper device.

[0016] In one embodiment, the moving direction of the wiper relative to the mounting bracket is set as the first direction. The mounting bracket is provided with at least one limiting portion, and each of the limiting portions extends along the first direction and is spaced apart in a direction perpendicular to the first direction. The elastic member is set as a spring, and the number of the springs is the same as the number of the limiting portions. One end of each spring is correspondingly sleeved on each of the limiting portions, and the other end of each spring is in contact and cooperation with the wiper. With such a design, the limiting portion can limit and guide the spring, ensuring that the spring expands and contracts along the first direction to correspondingly apply a restoring force along the first direction to the wiper, thereby ensuring that the wiper contacts the ground for water wiping and improving the reliability of the water wiping device.

[0017] In one embodiment, there is at least one driving mechanism, and each of the driving mechanisms is spaced apart and installed on the mounting bracket and is in transmission connection with the wiper. With such a design, by increasing the number of driving mechanisms, the driving force received by the wiper is more evenly distributed, ensuring that the wiper can move smoothly along the first direction relative to the mounting bracket and improving the reliability of the water wiping device.

[0018] In one embodiment, the mounting bracket is provided with at least one mounting portion, and each of the mounting portions is used for detachably connecting with the cleaning body. With such a design, the cleaning body can flexibly replace the water wiping device according to actual usage needs, improving the practicability of the cleaning equipment.

[0019] In one embodiment, the mounting bracket is provided with at least one first sliding portion extending along the first direction, and the wiper is provided with at least one second sliding portion, and each of the second sliding portions is in sliding cooperation with each of the first sliding portions correspondingly. With such a design, the mounting bracket can guide the wiper through the first sliding portion and the second sliding portion, ensuring that the wiper reciprocates along the first direction relative to the mounting bracket and improving the reliability of the water wiping device.

[0020] On the other hand, a cleaning equipment is provided, including a cleaning body and the water wiping device as described above, and the water wiping device is installed at the front end of the cleaning body.

[0021] For the cleaning equipment in the above embodiments, when the cleaning body is pushed forward, the driving mechanism drives the wiper to rise relative to the mounting bracket, so that the length of the wiper extending from the bottom of the mounting bracket is reduced, and the wiper is away from the ground, and water wiping is not realized. When the cleaning body is pulled backward, the driving mechanism drives the wiper to descend relative to the mounting bracket, so that the length of the wiper extending from the bottom of the mounting bracket is increased, and the wiper contacts the ground, ensuring that the wiper can effectively wipe the water stains generated when the cleaning body is pulled backward, and ensuring the cleaning effect of the cleaning equipment while meeting the user's overall habit of cleaning backward.

[0022] In one embodiment, the cleaning body includes a rotary brush and a top shell. The top shell covers the upper part of the rotary brush, and the water scraping device is installed at the front end of the top shell. Description of the Drawings

DETAILED DESCRIPTION

[0036] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, a wiper device 10 is provided, which is applied to a cleaning device 30 having a cleaning body 20. The wiper device 10 includes a mounting bracket 100, a wiper element 200 and a driving mechanism 300. The mounting bracket 100 is used to be mounted on the front end of the cleaning body 20. The wiper element 200 is movably matched with the mounting bracket 100. The driving mechanism 300 is mounted on the mounting bracket 100 and is in transmission connection with the wiper element 200, so that the length of the wiper element 200 extending from the bottom of the mounting bracket 100 is adjustable.

[0038] In the wiper device 10 of the above embodiment, when the cleaning body 20 is pushed forward, the driving mechanism 300 drives the wiper member 200 to rise relative to the mounting bracket 100, so that the length of the wiper member 200 extending from the bottom of the mounting bracket 100 is reduced, and the wiper member 200 is away from the ground, and no wiping is achieved. When the cleaning body 20 is pulled back, the driving mechanism 300 drives the wiper member 200 to descend relative to the mounting bracket 100, so that the length of the wiper member 200 extending from the bottom of the mounting bracket 100 is increased, and the wiper member 200 contacts the ground, ensuring that the wiper member 200 can effectively wipe off the water stains generated when the cleaning body 20 is pulled back, and ensuring the cleaning effect of the cleaning device 30 while satisfying the user's habit of cleaning backwards as a whole.

[0039] Among them, the wiper member 200 can be set as a wiper blade, a wiper strip or other wiper structures. The mounting bracket 100 can be mounted on the front end of the cleaning body 20 by means of snap connection, plug connection, screw connection or other connection means.

[0040] As Figure 5 shown, optionally, the mounting bracket 100 is provided with at least one mounting portion 130, and each mounting portion 130 is used for detachably connecting with the cleaning body 20. In this way, the cleaning body 20 can be flexibly replaced for the wiper device 10 according to actual usage needs, improving the practicability of the cleaning device 30.

[0041] Among them, the number of the mounting portions 130 can be flexibly adjusted according to actual usage needs. Specifically in this embodiment, the number of the mounting portions 130 is three, and the three mounting portions 130 are spaced along the length direction of the mounting bracket 100 (such as Figure 2 the direction shown by E in the figure). The mounting portion 130 can be set as a card slot, and the cleaning body 20 is provided with a buckle 202. The number of the buckles 202 is the same as the number of the card slots, and each buckle 202 is in corresponding snap-fit connection with each card slot.

[0042] Among them, the driving mechanism 300 can be any one of the existing technologies that can drive the wiper member 200 to move linearly relative to the mounting bracket 100. For example, a gear-rack driving structure, a lead screw-nut driving structure, or a telescopic driving structure, etc.

[0043] As Figure 1 and Figure 3 shown, in one embodiment, the driving mechanism 300 includes a driving member 310 and a transmission assembly 320. The driving member 310 is mounted on the mounting bracket 100 and is in transmission connection with the transmission assembly 320, and the transmission assembly 320 is in transmission connection with the wiper member 200.

[0044] As Figure 1 and Figure 3 shown, optionally, the mounting bracket 100 is provided with a mounting hole 110, and the driving member 310 is mounted in the mounting hole 110. In this way, the mounting hole 110 can play a positioning role to ensure that the driving member 310 can be quickly and accurately mounted at a preset position on the mounting bracket 100, so as to precisely control the length of the wiper member 200 extending from the bottom of the mounting bracket 100, improving the reliability of the wiper device 10.

[0045] Specifically in this embodiment, the driving member 310 is embedded in the mounting hole 110.

[0046] As Figure 1 and Figure 3As shown, in one embodiment, the driving member 310 is provided with a telescopic end 311. The transmission assembly 320 includes a transmission rope 321. One end of the transmission rope 321 is connected to the telescopic end 311, and the other end is connected to the wiper member 200.

[0047] Wherein, one end of the transmission rope 321 can be connected to the telescopic end 311 by means of clamping, plugging or other fixed assembly methods, and the other end of the transmission rope 321 can be connected to the wiper member 200 by means of clamping, plugging or other fixed assembly methods.

[0048] Such as Figure 1 and Figure 3 As shown, in one embodiment, the moving direction of the wiper member 200 relative to the mounting bracket 100 is set as the first direction (such as Figure 3 the direction shown as D in the figure), and the telescopic end 311 of the driving member 310 is telescopically arranged along a second direction intersecting the first direction. The transmission assembly 320 further includes a rolling member 322. The rolling member 322 is rotatably mounted on the mounting bracket 100 and is located between the telescopic end 311 of the driving member 310 and the wiper member 200 along the first direction. The transmission rope 321 located between the telescopic end 311 and the wiper member 200 is tensioned and wound around the rolling member 322, so that the transmission rope 321 between the rolling member 322 and the wiper member 200 is tensioned and arranged along the first direction instead of the original second direction. That is, the rolling member 322 can change the extension direction of the transmission rope 321 between it and the wiper member 200. In this way, the driving member 310 can be installed at different positions according to space requirements, improving the adaptability of the wiper device 10. In addition, the transmission rope 321 between the rolling member 322 and the wiper member 200 is arranged along the first direction, so that the transmission rope 321 exerts a driving force along the first direction on the wiper member 200, ensuring that the transmission rope 321 can pull the wiper member 200 to rise and improving the reliability of the wiper device 10.

[0049] Wherein, the first direction can be the vertical direction or an inclined direction set at an angle to the vertical direction, as long as it is ensured that when the length of the wiper member 200 extending from the bottom of the mounting bracket 100 decreases, the wiper member 200 is away from the ground, and when the length of the wiper member 200 extending from the bottom of the mounting bracket 100 increases, the wiper member 200 contacts the ground for wiping.

[0050] Specifically in this embodiment, the driving member 310 can be set as a push-pull electromagnet. The rolling member 322 can be set as a roller or a roller shaft. The transmission rope 321 can be set as a steel wire.

[0051] Such as Figure 1 、 Figure 3 、 Figure 6 and Figure 7As shown, optionally, the wiper device 10 further includes an elastic member 400. The elastic member 400 is installed between the mounting bracket 100 and the wiper member 200, and is configured to be compressed when the length of the wiper member 200 extending from the bottom of the mounting bracket 100 decreases, and to rebound and reset when the length of the wiper member 200 extending from the bottom of the mounting bracket 100 increases. Thus, when the cleaning body 20 is pushed forward, the push-pull electromagnet is energized, the push-pull electromagnet is in a pulling state, the telescopic end 311 is compressed to lift the steel wire, the elastic member 400 is compressed, the wiper member 200 is lifted upward, and moves to the lifted position (as Figure 4 shown), the wiper member 200 is away from the ground and does not perform wipering. When the cleaning body 20 is pulled backward, the push-pull electromagnet is de-energized, the push-pull electromagnet is in a pushing state, the telescopic end 311 extends and restores, the steel wire is lowered, the elastic member 400 rebounds and resets, so as to push the wiper member 200 downward, and move to the lowered position (as Figure 2 shown), the wiper member 200 contacts the ground, and wipering during the backward pulling process is realized, improving the practicability of the wiper device 10.

[0052] As Figure 1 , Figure 3 , Figure 6 and Figure 7 shown, optionally, the moving direction of the wiper member 200 relative to the mounting bracket 100 is set as the first direction. The mounting bracket 100 is provided with at least one limiting portion 120. Each limiting portion 120 extends along the first direction and is spaced apart along a direction perpendicular to the first direction. The elastic member 400 is set as a spring, and the number of springs is the same as the number of limiting portions 120. One end of each spring is correspondingly sleeved on each limiting portion 120, and the other end of each spring is in contact and cooperation with the wiper member 200. Thus, the limiting portion 120 can limit and guide the spring, ensuring that the spring expands and contracts along the first direction to correspondingly apply a restoring force along the first direction to the wiper member 200, thereby ensuring that the wiper member 200 contacts the ground for wipering, and improving the reliability of the wiper device 10.

[0053] Wherein, the number of the springs and the limiting portions 120 can both be flexibly adjusted according to actual use requirements. Specifically in this embodiment, the limiting portion 120 can be set as a limiting rib, and the number of limiting ribs is two. The two limiting ribs are spaced apart along the length direction of the mounting bracket 100. A gap is maintained between the limiting rib and the wiper member 200. One end of the spring away from the limiting rib is in contact and cooperation with the top wall of the wiper member 200.

[0054] As Figure 1 and Figure 3As shown, in one embodiment, there is at least one driving mechanism 300. Each driving mechanism 300 is spaced apart and installed on the mounting bracket 100, and is in transmission connection with the wiper member 200. In this way, by increasing the number of driving mechanisms 300, the driving force received by the wiper member 200 is more evenly distributed, ensuring that the wiper member 200 can move smoothly relative to the mounting bracket 100 in the first direction and improving the reliability of the wiper device 10.

[0055] Among them, the number of driving mechanisms 300 can be flexibly adjusted according to actual usage needs. Specifically in this embodiment, the number of driving mechanisms 300 is two. The two driving mechanisms 300 are both located on the side of the mounting bracket 100 close to the cleaning body 20, and are symmetrically arranged on the left and right sides of the mounting bracket 100 along the length direction of the mounting bracket 100.

[0056] As Figure 4 and Figure 8 shown, in one embodiment, the mounting bracket 100 is provided with at least one first sliding portion 140 extending in the first direction, and the wiper member 200 is provided with at least one second sliding portion 210. Each second sliding portion 210 is in sliding fit with each first sliding portion 140. In this way, the mounting bracket 100 can guide the wiper member 200 through the first sliding portion 140 and the second sliding portion 210, ensuring that the wiper member 200 reciprocates relative to the mounting bracket 100 in the first direction and improving the reliability of the wiper device 10.

[0057] Among them, the number of the first sliding portion 140 and the second sliding portion 210 can both be flexibly adjusted according to actual usage needs. Specifically in this embodiment, the first sliding portion 140 is set as a first guiding chute, and the first guiding chute extends to the bottom wall of the mounting bracket 100. The second sliding portion 210 is set as a first guiding rib. The number of the first guiding chutes is three, and the three first guiding chutes all extend in the first direction and are spaced apart along the length direction of the mounting bracket 100. The number of the first guiding ribs is the same as that of the first guiding chutes, and the three first guiding ribs are in sliding fit with the three first guiding chutes correspondingly.

[0058] As Figure 8 and Figure 9 shown, optionally, the wiper member 200 is further provided with at least one third sliding portion 220, and the cleaning body 20 is further provided with at least one fourth sliding portion 201 extending in the first direction. Each third sliding portion 220 is in sliding fit with each fourth sliding portion 201. In this way, the cleaning body 20 can guide the wiper member 200 through the third sliding portion 220 and the fourth sliding portion 201, ensuring that the wiper member 200 reciprocates relative to the mounting bracket 100 in the first direction and improving the reliability of the wiper device 10.

[0059] Among them, the numbers of the third sliding part 220 and the fourth sliding part 201 can both be flexibly adjusted according to actual usage needs. Specifically in this embodiment, the fourth sliding part 201 is set as a second guiding chute, and the second guiding chute extends to the bottom wall of the top shell 22. The third sliding part 220 is set as a second guiding rib. The number of the second guiding chutes is three, and the three second guiding chutes all extend in the first direction and are arranged at intervals along the length direction of the mounting bracket 100. The number of the second guiding ribs is the same as that of the second guiding chutes, and the three second guiding ribs are slidably matched with the three second guiding chutes correspondingly.

[0060] As Figure 8 shown, optionally, the bottom of the wiper 200 is provided in a pointed shape. In this way, the bottom of the wiper 200 is prone to elastic deformation to keep in contact with the ground, ensuring that the wiper 200 effectively wipes water and improving the reliability of the wiper device 10.

[0061] As Figure 2 and Figure 4 shown, in one embodiment, a cleaning device 30 is provided, which includes a cleaning body 20 and the wiper device 10 in any of the above embodiments, and the wiper device 10 is installed at the front end of the cleaning body 20.

[0062] For the cleaning device 30 in the above embodiment, when the cleaning body 20 is pushed forward, the driving mechanism 300 drives the wiper 200 to rise relative to the mounting bracket 100, so that the length of the wiper 200 extending from the bottom of the mounting bracket 100 is reduced, and the wiper 200 is away from the ground, and water wiping is not achieved. When the cleaning body 20 is pulled backward, the driving mechanism 300 drives the wiper 200 to descend relative to the mounting bracket 100, so that the length of the wiper 200 extending from the bottom of the mounting bracket 100 is increased, and the wiper 200 contacts the ground, ensuring that the wiper 200 can effectively wipe dry the water stains generated when the cleaning body 20 is pulled backward, and ensuring the cleaning effect of the cleaning device 30 while meeting the user's overall habit of cleaning backward.

[0063] It should be noted that in this application, the cleaning device 30 is taken as an example of a floor washer for detailed description. In other embodiments, the cleaning device 30 can also be set as a sweeper or a mopping machine, etc.

[0064] As Figure 2 、 Figure 4 and Figure 7 shown, further, the cleaning body 20 includes a rolling brush 21 and a top shell 22, the top shell 22 covers the upper part of the rolling brush 21, and the wiper device 10 is installed at the front end of the top shell 22. In this way, the wiper device 10 is located at the front end of the rolling brush 21, ensuring that the wiper 200 can effectively wipe dry the water stains generated when the rolling brush 21 retreats when the cleaning body 20 is pulled backward, and improving the cleaning effect of the cleaning device 30.

[0065] Specifically in this embodiment, the fourth sliding part 201 and the buckle 202 are both arranged at the front end of the top shell 22.

[0066] As Figure 2 and Figure 4 shown, optionally, the cleaning body 20 further includes an upper shell 23, a lower shell 24, a front push wiper 25, a power assist wheel 26 and a sewage suction port. The upper shell 23 and the lower shell 24 are detachably connected, the front end of the top shell 22 is detachably connected to the upper shell 23, the roller brush 21 is located at the front end of the lower shell 24, the power assist wheel 26 is located at the rear end of the lower shell 24, and the front push wiper 25 is installed at the front end of the lower shell 24 and is used to scrape dry the water stains on the ground. The working principle of the cleaning device 30 is as follows: the vacuum motor generates suction force, the clean water in the clean water tank is sprayed onto the roller brush 21 by the water pump. Driven by the roller brush motor, the roller brush 21 starts to rotate, generates friction with the ground, scrapes up the dust and dirt on the ground, dissolves them in water to become sewage, and sucks them away through the sewage suction port. At the same time, the wiper parts 200 on both the front and rear sides of the roller brush 21 and the front push wiper 25 scrape dry the water stains on the ground. The power assist wheel 26 can rotate forward and backward during the cleaning process to make the forward push and backward pull more labor-saving. Thus, a cleaning is completed.

[0067] To facilitate further understanding of the structure of the wiper device 10, the present application takes one of the ways of assembling the wiper device 10 to the cleaning body 20 as an example for detailed description:

[0068] During assembly, first, after connecting one end of the transmission rope 321 to the wiper part 200, the wiper part 200 is installed at the bottom of the mounting bracket 100 by means of the first sliding part 140 and the second sliding part 210. Secondly, the roller is installed at the axle of the mounting bracket 100, the spring is correspondingly installed into the limiting part 120, the driving part 310 is correspondingly installed in the mounting hole 110, and the other end of the transmission rope 321 is connected to the telescopic end 311 of the driving part 310 to form the wiper device 10. Finally, the wiper device 10 is detachably installed at the front end of the top shell 22 in the cleaning body 20 through the mounting part 130 to complete the assembly of the wiper device 10.

[0069] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0070] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0071] In this application, unless otherwise clearly specified and limited, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0072] In this application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher horizontal level than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower horizontal level than the second feature.

[0073] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it may be directly on the other element or there may also be an intermediate element. If 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 at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0074] It should also be understood that when interpreting the connection relationship or position relationship of elements, although not explicitly described, the connection relationship and position relationship are interpreted to include an error range, and this error range should be within the acceptable deviation range of a specific value determined by those skilled in the art. For example, "about", "approximate" or "substantially" may mean within one or more standard deviations, which is not limited here.

[0075] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, 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, it should be considered as the scope recorded in this specification.

[0076] The above embodiments only express several implementation manners of the present application, and their descriptions are relatively specific and detailed. However, it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
