Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a floor brush assembly and cleaning equipment. Background Technology

[0002] A floor scrubber is an intelligent cleaning device that combines vacuuming, mopping, and self-cleaning functions. It is widely used for deep cleaning of hard floors in homes, commercial spaces, and other locations.

[0003] In related technologies, one of the core components of a floor scrubber is the floor brush assembly, which includes a base, a roller brush, a drive mechanism, and a floor brush squeegee. The roller brush is mounted on the base, and the floor brush squeegee is mounted on the base and located behind the roller brush. Both the roller brush and the floor brush squeegee can make frictional contact with the ground. The base also has a suction port, which is located in the sealed space formed by the roller brush and the floor brush squeegee. Air intake channels connected to the suction port are formed on both the left and right sides of the base. The drive mechanism is used to drive the roller brush to rotate around its own axis. In this way, through the rotation of the roller brush and the negative pressure of the suction port, particulate matter and sewage on the ground are sucked into the sewage tank inside the floor scrubber.

[0004] However, in related technologies, the air intake area and stroke of the left and right air intake channels in the floor brush assembly are different, which causes the airflow of the left and right air intake channels to collide at the dust inlet and generate vortices, resulting in dust particles easily accumulating near the dust inlet and failing to be effectively sucked in. Utility Model Content

[0005] In view of the above problems, this application provides a floor brush component and cleaning device, which aims to solve the problem that particles such as rice tend to accumulate near the suction port, thereby improving the effective suction of particles such as rice at the suction port and thus improving the user's experience.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] The first aspect of this application provides a floor brush assembly, including: a base and a roller brush, wherein the roller brush is rotatably mounted on the base, and a portion of the structure of the roller brush extends out of the bottom of the base;

[0008] The base has a dust suction chamber inside, and a dust suction port is provided at one end of the dust suction chamber facing the roller brush. The base has a first air duct and a second air duct that are respectively connected to the dust suction port. The first air duct and the second air duct are arranged side by side on both sides of the dust suction port along the axial direction of the roller brush.

[0009] The roller brush has a first bristle area and a second bristle area located on both sides of the first bristle area along its axial direction. The first bristle area is disposed opposite to the dust suction port. Along the radial direction of the roller brush, the contour surface of the first bristle area protrudes beyond the contour surface of the second bristle area.

[0010] In the floor brush assembly provided in this application embodiment, a first bristle area and a second bristle area are provided on the roller brush. The first bristle area is located opposite the suction port, and the second bristle area is located on both sides of the first bristle area. Both the first bristle area and the second bristle area extend circumferentially along the roller brush, and along the radial direction of the roller brush, the contour surface of the first bristle area protrudes beyond the contour surface of the second bristle area. In this way, the first bristle area can effectively sweep particles such as rice accumulated in front of the suction port to the suction port, and the negative pressure of the suction port will adsorb the particles such as rice into the suction chamber, thereby solving the problem of the accumulation of particles such as rice in front of the suction port, and thus improving the user experience.

[0011] In some alternative implementations, the stiffness of the bristles in the first bristle region is greater than that of the bristles in the second bristle region.

[0012] This improves the cleaning power of the first brush area and enhances its wear resistance.

[0013] In some alternative implementations, the bristles in the first bristle area are plastic bristles.

[0014] In this way, the cost is reduced while ensuring the wear resistance of the first bristle area.

[0015] In some alternative embodiments, the contour surface of the first bristle area protrudes 1 mm to 5 mm beyond the contour surface of the second bristle area.

[0016] This ensures the reliability of the first brush zone in sweeping particles such as rice from the front of the suction port to the suction port.

[0017] In some alternative embodiments, the width of the first bristle area along the axial direction of the roller brush is 5 mm to 35 mm.

[0018] This ensures that the width of the first brush bristle area covering the accumulation area of ​​rice and other particles is covered along the roller brush axis, thereby improving the reliability of the first brush bristle area in sweeping the rice and other particles accumulated in front of the suction port to the suction port.

[0019] In some alternative implementations, the contour surface of the first bristle area protrudes 2 mm beyond the contour surface of the second bristle area;

[0020] Along the axial direction of the roller brush, the width of the first bristle area is 10 mm.

[0021] This further ensures the reliability of the first brush zone in sweeping particles such as rice from the front of the suction port to the suction port.

[0022] In some optional embodiments, the floor brush assembly further includes a roller brush strip mounted inside the base and located behind the roller brush and above the suction port. The roller brush strip is configured to directly contact the roller brush, and has an avoidance recess at a position corresponding to the first bristle area, such that the distance between the bottom wall of the avoidance recess and the outer surface of the first bristle area is greater than or equal to 0.

[0023] In this way, airflow can not only enter the suction port from the first and second air ducts, but also from the gaps between the bristles in the first bristle area and from the position of the roller brush bar opposite to the first bristle area. This effectively prevents the airflow in the first and second air ducts from colliding at the suction port, thereby improving the phenomenon of vortex formation near the suction port.

[0024] In some alternative embodiments, the depth of the avoidance recess is 1 mm to 5 mm.

[0025] This ensures that the airflow enters the suction port from the position opposite to the first brush bristle area, thus reducing the vortex phenomenon near the suction port.

[0026] In some optional embodiments, the first bristle area includes a guide section and a cleaning section arranged back and forth along the rotation direction of the roller brush, the guide section being located on the front side of the rotation direction, and the bristles of the guide section being inclined towards the front side of the rotation direction of the roller brush.

[0027] The cleaning section is located behind the guide section, and the bristles of the cleaning section are arranged along the radial direction of the roller brush.

[0028] In this way, during the cleaning process, the first part of the first brush section that comes into contact with the ground is the guide section, which directs the airflow towards the suction port and disturbs the airflow. This effectively prevents the airflow between the first and second air ducts from colliding and creating eddies near the suction port. Afterward, the brushes of the cleaning section can sweep particles such as rice in front of the suction port to the suction port, where the negative pressure will draw the particles into the suction chamber, thus avoiding the problem of particles such as rice accumulating near the suction port.

[0029] In some alternative embodiments, the floor brush assembly further includes a floor brush squeegee disposed on the rear side of the roller brush and connected to the base, the floor brush squeegee having an air inlet notch at a position opposite to the dust suction port.

[0030] In this way, the airflow can also enter the dust suction port from the rear through the air intake opening at the floor brush blade, so as to further generate vortex phenomenon by colliding the airflow in the first and second air ducts at the dust suction port.

[0031] A second aspect of this application provides a cleaning device, including: a body and a floor brush assembly provided in the first aspect, wherein the body is disposed on the floor brush assembly.

[0032] The cleaning equipment provided in this application embodiment has the same beneficial effects as the floor brush assembly described above, and will not be repeated here.

[0033] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the floor brush components and cleaning equipment provided by the embodiments of this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation methods.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0051] A floor scrubber is an intelligent cleaning device that combines vacuuming, mopping, and self-cleaning functions. It is widely used for deep cleaning of hard floors in homes, commercial spaces, and other locations.

[0052] In some embodiments, one of the core components of the floor scrubber is a floor brush assembly, which includes a base, a roller brush, a drive mechanism, and a floor brush squeegee. The roller brush is rotatably mounted on the base, i.e., along the axial direction of the roller brush, with both ends of the roller brush rotatably mounted on the base. The drive mechanism is used to drive the roller brush to rotate around its own axis. The floor brush squeegee is mounted on the base and located behind the roller brush. The roller brush includes a circular cross-section roller core and bristles surrounding the outer peripheral wall of the roller core and extending circumferentially along the roller core. The bristles have a certain length in the radial direction of the roller core, and the bristles are usually made of fiber material. In this way, the bristles can dry mop or wet mop the floor.

[0053] In addition, a first air duct (e.g., the left air inlet duct) and a second air duct (e.g., the right air inlet duct) are arranged in parallel along the axis of the roller brush and the floor brush shavings. The base has a dust suction chamber inside, and the end of the dust suction chamber facing the roller brush has a dust suction port. Along the axis of the roller brush, the dust suction port is located between the first air duct and the second air duct and is connected to the first air duct and the second air duct respectively. In this way, when cleaning the floor, the rotation of the roller brush and the negative pressure of the dust suction port suck the particles and sewage on the floor into the sewage tank inside the floor scrubber.

[0054] However, in the floor brush assembly, the roller brush, brush blades, drive mechanism, and water pump that supplies water to the roller brush are mounted on the base. The drive mechanism, for example, includes a drive motor. Due to the layout of each component on the base, the air intake area and formation of the first and second air ducts are different, resulting in different airflow speeds and flow rates in the first and second air ducts. For example, the drive mechanism is usually located in the second air duct (i.e., the right-side air intake channel) and connected to the roller brush to drive the roller brush to rotate around its own axis. This causes the airflow speed and flow rate of the first air duct to be greater than that of the second air duct. As a result, the airflows flowing towards the suction port through the first and second air ducts will collide with each other in the upper right of the suction port, and a vortex will appear directly in front of and below the suction port. This causes particles such as rice to be unable to be sucked into the suction port due to the vortex phenomenon, resulting in the accumulation of particles such as rice in front of the suction port, affecting the cleaning effect and the user experience.

[0055] To overcome the above-mentioned defects, this application provides a floor brush assembly and cleaning device, which aims to solve the problem that particles such as rice tend to accumulate near the suction port, thereby improving the effective suction of particles such as rice at the suction port and thus enhancing the user's experience.

[0056] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0057] This application provides a cleaning device, which includes, but is not limited to, a floor scrubber. Taking a floor scrubber as an example, the cleaning device includes a body and a floor brush assembly. The body is mounted on the floor brush assembly. The main control circuit board, dust cup, and other structures can be installed inside the body. In addition, the user can push and pull the cleaning device by the body, so that the user can operate the cleaning device while standing, which improves the user's comfort when operating the cleaning device.

[0058] Please refer to Figure 1 As shown, the floor brush assembly 10 includes a base 100 and a roller brush 200, along the length direction of the base 100 (e.g., ...). Figure 1In the X direction, the two ends of the roller brush 200 are rotatably mounted on the base 100, and part of the structure of the roller brush 200 extends out of the bottom of the base 100 so that the bristles on the roller brush 200 can directly contact the ground to clean the ground.

[0059] Please refer to Figure 2 As shown, the base 100 has a dust suction chamber 110 inside, and the end of the dust suction chamber 110 facing the roller brush 200 has a dust suction port 111. The base 100 has a first air duct 400 and a second air duct 500 that are respectively connected to the dust suction port 111. The first air duct 400 and the second air duct 500 are arranged side by side on both sides of the dust suction port 111 along the X direction (such as the axial direction of the roller brush 200).

[0060] For example, the floor brush assembly 10 also includes a floor brush squeegee 300, which is disposed on the rear side of the roller brush 200 and connected to the base 100, for example, in Figure 1 In the middle, along the Y direction, the floor brush squeegee 300 is located behind the roller brush 200. For example, the floor brush squeegee 300 is usually made of rubber, and the bristles of the roller brush 200 are usually made of fiber. A first air duct 400 and a second air duct 500 are formed between the floor brush squeegee 300 and the roller brush 200, which are arranged side by side and connected along the axial direction of the roller brush 200. That is, the first air duct 400 and the second air duct 500 are arranged side by side and connected along the X direction.

[0061] In addition, the floor brush assembly 10 also includes a negative pressure device, which is used to generate negative pressure in the suction chamber 110 so that dust particles near the suction port 111 can be adsorbed into the suction chamber 110 by the negative pressure. In this way, when the cleaning equipment is running, the external airflow can flow towards the suction port 111 through the first air duct 400 and the second air duct 500 under the action of negative pressure. The airflow can bring particles such as rice and dust into the suction port 111.

[0062] For example, in Figure 2 and Figure 3 In the middle, the air intake channel formed between the floor brush strip 300 and the roller brush 200 on the right side of the suction port 111 is the second air duct 500. Figure 3 In the middle, the air intake channel formed between the floor brush strip 300 and the roller brush 200 on the left side of the suction port 111 is the first air duct 400, such as... Figures 1 to 4 As shown, along the X direction, the left end of the first air duct 400 is connected to the outside air, and the right end of the second air duct 500 is connected to the outside air.

[0063] Because the airflow speed and flow rate differ in the first air duct 400 and the second air duct 500, a vortex is formed in front of the suction port 111, making it difficult for particles such as rice to be sucked into the suction port 111. Therefore, in this embodiment of the application, as... Figure 1 and Figure 6 As shown, the roller brush 200 has a first bristle area 210 and a second bristle area 220 located on both sides of the first bristle area 210. The first bristle area 210 is located opposite to the suction port 111, and the second bristle area 220 is located on both sides of the first bristle area 210. Both the first bristle area 210 and the second bristle area 220 extend circumferentially along the roller brush 200. Along the radial direction of the roller brush 200, the contour surface of the first bristle area 210 protrudes from the contour surface of the second bristle area 220. That is, the bristles of the first bristle area 210 are longer than the bristles of the second bristle area 220.

[0064] Understandably, by setting a first bristle area 210 and a second bristle area 220 on the roller brush 200, with the first bristle area 210 located opposite the suction port 111 and the second bristle area 220 located on both sides of the first bristle area 210, and both the first bristle area 210 and the second bristle area 220 extending circumferentially along the roller brush 200, and with the radial direction of the roller brush 200, the contour surface of the first bristle area 210 protruding beyond the contour surface of the second bristle area 220, the first bristle area 210 can effectively sweep rice and other particles accumulated in front of the suction port 111 to the suction port 111, and through the negative pressure of the suction port 111, adsorb the rice and other particles into the suction chamber 110, thereby solving the problem of rice and other particles accumulating in front of the suction port 111, and thus improving the user experience.

[0065] For example, the bristles of the first bristle area 210 are made of the same material as the bristles of the second bristle area 220, such as fibers. The bristle length of the first bristle area 210 is greater than that of the bristles of the second bristle area 220. In this way, as the bristles of the first bristle area 210 rotate with the roller brush 200, the longer bristles can sweep particles such as rice in front of the suction port 111 toward the suction port 111.

[0066] In another example, the bristles of the first bristle area 210 are harder than the bristles of the second bristle area 220. This can improve the cleaning power of the first bristle area 210 and enhance its wear resistance.

[0067] Understandably, since the bristles of the first bristle area 210 are longer than those of the second bristle area 220, the bristles of the first bristle area 210 experience more wear. To improve the wear resistance of the bristles of the first bristle area 210, the material of the bristles of the first bristle area 210 is plastic bristles, for example, nylon bristles, while the bristles of the second bristle area 220 are, for example, fiber bristles. In this way, the fiber bristles of the second bristle area 220 can improve the cleaning effect on the floor, while the bristles of the first bristle area 210 can improve the force of sweeping particles such as rice accumulated in front of the suction port 111 to the suction port 111, and at the same time improve the wear resistance of the bristles of the first bristle area 210, thereby increasing the service life of the roller brush 200 and reducing costs.

[0068] In addition, when the bristles of the first bristle area 210 are made of a relatively hard material such as plastic, there are gaps between the bristles in the first bristle area 210. In this way, in addition to entering the suction port 111 from the first air duct 400 and the second air duct 500, the airflow can also enter the suction port 111 from the front side of the roller brush 200 through the gaps between adjacent bristles in the first bristle area 210. This allows the airflow entering the suction port 111 through the first bristle area 210 to effectively prevent the airflow in the first air duct 400 and the second air duct 500 from colliding with each other at the suction port 111 and generating vortices. Furthermore, the airflow entering through the first bristle area 210 can also carry particles such as rice accumulated on the front side of the suction port 111 towards the suction port 111, thereby further preventing the accumulation of particles such as rice on the front side of the suction port 111, improving the cleaning effect and the user experience.

[0069] The contour surface of the first brush area 210 protrudes 1mm to 5mm beyond the contour surface of the second brush area 220. This ensures the reliability of the first brush area 210 in sweeping particles such as rice from the front of the suction port 111 to the suction port 111.

[0070] For example, such as Figure 6 As shown, the height by which the contour surface of the first bristle area 210 protrudes above the contour surface of the second bristle area 220 is, for example, represented by 'a'. The height 'a' of the first bristle area 210 protruding above the contour surface of the second bristle area 220 is 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm, to ensure the reliability of the first bristle area 210 in sweeping particles such as rice accumulated in front of the suction port 111 towards the suction port 111.

[0071] In addition, along the axial direction of the roller brush 200, the width of the first bristle area 210 is 5mm to 35mm. This ensures that the first bristle area 210 covers the width of the rice and other particle accumulation area along the axial direction of the roller brush 200, thereby improving the reliability of the first bristle area 210 in sweeping the rice and other particles accumulated in front of the suction port 111 to the suction port 111.

[0072] like Figure 6 As shown, the width of the first brush area 210 is represented by b, for example. The width b of the first brush area 210 is 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, etc. This ensures that the width of the first brush area 210 can effectively cover the width of rice and other particles accumulated in front of the suction port 111 in the axial direction of the roller brush 200, thereby improving the cleaning reliability of the first brush area 210.

[0073] For example, the contour surface of the first bristle area 210 protrudes 2 mm beyond the contour surface of the second bristle area 220; along the axial direction of the roller brush 200, the width of the first bristle area 210 is 10 mm, thus further ensuring the reliability of the first bristle area 210 in sweeping particles such as rice in front of the suction port 111 to the suction port 111.

[0074] Please refer to Figure 1 and Figure 5 As shown, the floor brush assembly 10 also includes a roller brush scraper 600, which is installed inside the base 100 and located behind the roller brush 200 and above the suction port 111. When the roller brush 200 is driven by the drive motor to rotate around its own axis, the roller brush scraper 600 and the bristles of the roller brush 200 are press-fitted to scrape and squeeze the sewage and debris and other particles on the bristles, so that the sewage and debris and other particles fall into the suction port 111 and are sucked into the suction chamber 110.

[0075] To further improve the cleaning effect of the cleaning equipment and avoid the accumulation of rice particles and other debris in front of the suction port 111, in this embodiment of the application, such as Figure 7 and Figure 8As shown, the roller brush 600 has a relief recess 610 at the position corresponding to the first bristle area 210, so that the distance between the relief recess 610 and the first bristle area 210 is greater than or equal to 0. For example, when the distance between the roller brush 600 and the first bristle area 210 is 0, the roller brush 600 scrapes away sewage and other substances on the first bristle area 210. When the distance between the roller brush 600 and the first bristle area 210 is greater than 0, the airflow can not only enter the suction port 111 from the first air duct 400 and the second air duct 500, but also from the gaps between the bristles in the first bristle area 210 and the position opposite to the first bristle area 210, so as to effectively prevent the airflow in the first air duct 400 and the second air duct 500 from colliding at the suction port 111, thereby improving the phenomenon of vortex generation near the suction port 111.

[0076] Please continue to refer to Figure 8 As shown, the depth of the avoidance recess 610 is 1mm to 5mm. For example, if the depth of the avoidance recess 610 on the roller brush 600 is represented by c, then the depth c of the avoidance recess 610 is 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm. In this way, the airflow can be ensured to enter the suction port 111 from the position opposite to the first brush bristle area 210, so as to improve the phenomenon of vortex formation near the suction port 111.

[0077] Please refer to Figure 7 and Figure 8 As shown, in order to improve the cleaning power of the roller brush squeegee 600, in this embodiment of the application, the side of the roller brush squeegee 600 that contacts the bristles of the roller brush 200 has comb teeth. In this way, when scraping the bristles, the comb teeth on the roller brush squeegee 600 can comb the bristles to improve the cleanliness of the bristles and the cleaning effect.

[0078] In order to ensure the structural strength of the roller brush scraper 600, the roller brush scraper 600 can be made of metal materials such as iron, copper, aluminum alloy, and stainless steel.

[0079] To further improve the cleaning effect, in this embodiment, the first bristle area 210 includes a guide section and a sweeping section arranged front and back along the rotation direction of the roller brush 200. The guide section is located on the front side of the rotation direction, and the bristles of the guide section are inclined towards the front side of the rotation direction of the roller brush 200. The sweeping section is located on the rear side of the guide section, and the bristles of the sweeping section are arranged along the radial direction of the roller brush 200.

[0080] In this way, during the cleaning process, the first part of the first brush bristle area 210 that comes into contact with the ground is the guide section, which directs the airflow toward the suction port 111 and disturbs the airflow. This can effectively prevent the airflow between the first air duct 400 and the second air duct 500 from colliding and generating eddies near the suction port 111. Afterward, the bristles of the cleaning section can sweep particles such as rice in front of the suction port 111 to the suction port 111, so that the negative pressure of the suction port 111 can adsorb the particles such as rice into the suction chamber 110, thereby avoiding the problem of the accumulation of particles such as rice near the suction port 111.

[0081] For example, the guide section is located at the front end of the rotation direction and has a certain tilt angle towards the front, such as 45° or an approximately 45° tilt angle. That is, when the roller brush 200 rotates, the oblique bristles of the guide section are the first to contact the ground; while the brush of the sweeping section follows the guide section and is located at the rear end of the rotation direction. The brush of the sweeping section contacts the ground later, and the brush of the sweeping section has vertical bristles that extend radially along the roller to sweep the rice and other particle areas in front of the suction port 111 to the suction port 111.

[0082] In some embodiments, the floor brush 300 has an air inlet at the position opposite to the dust suction port 111. For example, the floor brush 300 has an air inlet at the position directly opposite to the dust suction port 111. In this way, the airflow can also enter the dust suction port 111 from the rear through the air inlet at the floor brush 300, so as to further prevent the airflow in the first air duct 400 and the second air duct 500 from colliding at the dust suction port 111 and generating a vortex.

[0083] In summary, the floor brush assembly provided in this application embodiment has a first bristle area and a second bristle area on the roller brush. The first bristle area is located opposite the suction port, and the second bristle area is located on both sides of the first bristle area. Both the first and second bristle areas extend circumferentially along the roller brush, and the contour surface of the first bristle area protrudes from the contour surface of the second bristle area along the radial direction of the roller brush. In this way, the first bristle area can effectively sweep particles such as rice accumulated in front of the suction port to the suction port, and the negative pressure of the suction port will adsorb the particles such as rice into the suction chamber, thereby solving the problem of the accumulation of particles such as rice in front of the suction port and improving the user experience.

[0084] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0085] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0086] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0087] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
