[0003] In related technologies, integrated cooktops include a head unit, a cooktop body, and a lower unit. The head unit has an air inlet duct, and the lower unit has a flue. The air inlet duct and the flue are connected. During cooking, the fumes generated by the cooktop body are discharged to the outside through the air inlet duct and the flue.
[0004] With the increasing demands for integrated cooktop performance, there is an urgent need for an integrated cooktop that can efficiently remove cooking fumes. Summary of the Invention
[0005] This application provides a head assembly and an integrated stove that can improve the efficiency and effectiveness of fume extraction, and further enhance the fume exhaust performance of the integrated stove.
[0006] To achieve the above objectives, this application adopts the following technical solution:
[0007] In a first aspect, this application provides a head assembly, including: a smoke collection hood and a smoke baffle disposed above the smoke collection hood, the smoke collection hood having a smoke collection cavity extending in a vertical direction, and the front side of the smoke baffle having an air inlet communicating with the smoke collection cavity;
[0008] The smoke collection chamber has a flow guiding structure at a position opposite to the air inlet. The flow guiding structure is configured to guide and gather the oil fumes entering through the air inlet into the smoke collection chamber.
[0009] In some embodiments, along the transverse cross section, the flow guiding structure includes at least two flow guiding sections connected in sequence, with adjacent flow guiding sections having different profile shapes; the two ends of the flow guiding structure are respectively connected to the two sides of the air inlet.
[0010] In some embodiments, at least two of the guide sections have curved profiles, and adjacent guide sections have different bending directions and different radii of curvature.
[0011] In some embodiments, along the direction from the front to the rear of the smoke collection chamber, the distance between the two sides of the flow guiding structure and the air inlet is less than the distance between the flow guiding structure near the middle area and the air inlet.
[0012] In some embodiments, the smoke collection chamber has a smoke gathering structure on the side opposite to the air inlet. The smoke gathering structure is connected to the smoke baffle and forms a smoke gathering area between the smoke baffle and the smoke gathering area. The smoke gathering area is located between the air inlet and the smoke collection chamber. The smoke gathering area is configured to gather the oil fumes entering through the air inlet and allow them to enter the smoke collection chamber.
[0013] In some embodiments, the lowest position of the smoke collection structure is higher than the highest position of the air inlet, or is level with the highest position of the air inlet.
[0014] In some embodiments, along the transverse section, the cross-sectional area of the smoke collection zone is larger than the cross-sectional area of the smoke collection chamber on the side closer to the air inlet.
[0015] In some embodiments, the smoke-collecting structure is a curved structure extending in a vertical direction, the curved structure bending toward the side away from the air inlet.
[0016] In some embodiments, the smoke collection hood includes a first hood and a second hood, the first hood and the second hood together forming a smoke collection cavity, the smoke gathering structure is disposed on the second hood and connected to the second hood, and the second hood has a planar structure.

The smoke collection hood has a smoke collection chamber, and the front side of the smoke baffle plate has an air inlet communicating with the smoke collection chamber. A flow guiding structure is located opposite the air inlet in the smoke collection chamber. This flow guiding structure guides the oil fumes entering through the air inlet, causing the oil fumes to quickly and evenly gather within the smoke collection chamber and then be discharged through the flue under the action of a negative pressure fan. This allows the range hood to improve its oil fume removal efficiency and effect under the same power, while reducing its power consumption. During the flow of oil fumes, the flow guiding structure creates a certain flow resistance, reducing the pressure of the oil fumes before they enter the range hood, reducing the impact of oil fumes on the range hood, improving the stability of the integrated cooktop, and reducing the operating noise of the integrated cooktop.

[0037] 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.
[0038] First, see Figure 1 Define the length direction of the integrated stove 10 as the X direction, the width direction of the integrated stove 10 as the Y direction, and the height and vertical directions of the integrated stove 10 as the Z direction.
[0039] Firstly, see... Figure 1 This application provides a cooktop assembly 100, applied to an integrated stove 10. The integrated stove 10 includes a lower unit 200, a stove body 300, and the cooktop assembly 100. The lower unit 200 mainly provides storage cabinet space and space for installing the range hood, while the stove body 300 mainly provides the cooktop for cooking. The cooktop assembly 100 is mainly used in conjunction with the range hood to generate negative pressure to remove cooking fumes. It is easy to understand that the cooktop assembly 100, stove body 300, and lower unit 200 are arranged sequentially along the Z-direction and relatively fixedly connected to improve the stability of the integrated stove 10.
[0040] In some embodiments, the head assembly 100 includes a fume hood 110, which has a fume collection chamber 111 and an air inlet 121 communicating with the fume collection chamber 111. The fume collection chamber 111 is connected to the flue of the range hood installed in the lower unit 200. In this way, the fumes generated during cooking can enter the fume collection chamber 111 along the air inlet 121 under the negative pressure of the range hood and are finally discharged through the flue.
[0041] In some embodiments, along the Z direction, the air inlet 121 is located on the side of the head assembly 100 away from the stove body 300. In this way, the wall surface of the smoke collection hood 110 of the head assembly 100 extending along the Z direction prevents the flame of the stove body 300 from being directly sucked into the air inlet. At the same time, the wall surface of the smoke collection hood 110 facing the stove body 300 guides the flow of oil fumes, causing the oil fumes to rise along the wall surface of the smoke collection hood 110 and then be sucked into the receiving space of the smoke collection hood 110.
[0042] With the changes in the function and appearance of the integrated stove 10, in some embodiments, the head assembly 100 also includes a smoke baffle 120. The smoke baffle 120 is disposed on the top of the smoke collection hood 110. At least part of the smoke baffle 120 and the stove body 300 are opposite each other in the Z direction to block and guide the oil fumes generated during cooking, reduce the dispersion of oil fumes, make the oil fumes accumulate, and suck away the oil fumes under the negative pressure of the range hood.
[0043] It should be noted that the smoke baffle 120 and the smoke collection hood 110 can be an integral independent component, or the smoke baffle 120 and the smoke collection hood 110 can be two separate components, which are fixedly connected to each other. In this way, the air inlet 121 can be set on the smoke baffle 120 or the integrated hood.
[0044] See Figure 1 , Figure 2 , Figure 3 In one specific embodiment, the air inlet 121 is located on the smoke baffle 120, and the air inlet 121 is located on the front side of the smoke baffle 120, that is, the air inlet 121 is located on the wall surface of the smoke baffle 120 facing the stove body 300 along the Y direction.
[0045] In some embodiments, the smoke baffle 120 is inclined relative to the side of the smoke collection hood 110 facing the stove body 300. In this way, the wall surface of the smoke baffle 120 facing the stove body 300 along the Z direction forms a blocking and gathering effect on the oil fumes. The oil fumes are further drawn into the smoke collection chamber 111 through the air inlet 121 by the range hood.
[0046] The structure of the smoke collection chamber 111 affects the effectiveness of fumes extraction. In related technologies, the cross-sectional shape of the smoke collection chamber 111 is often square. This allows the fumes to flow along the chamber wall as they enter, meaning the chamber wall guides the flow of fumes. However, after the fumes enter the smoke collection chamber 111 through the air inlet 121, they cannot be collected, resulting in a decrease in the efficiency and effectiveness of the fume extraction by the head assembly 100.
[0047] To address this technical deficiency, in one embodiment of this application, the smoke collection chamber 111 has a flow guiding structure 112. The flow guiding structure 112 is positioned in the smoke collection chamber 111 along the Y-direction opposite to the air inlet 121, guiding and concentrating the fumes entering from the air inlet 121. After entering the smoke collection chamber 111 through the air inlet 121, the fumes are concentrated at a specific location within the smoke collection chamber 111 under the action of the flow guiding structure 112, and then discharged through the flue under the action of a negative pressure fan. This allows the range hood to improve its fume removal efficiency and effectiveness at the same power level, further reducing the power consumption of the range hood. During the flow of fumes, the flow guiding structure 112 generates a certain flow resistance, further reducing the pressure of the fumes before they enter the air inlet 121 of the range hood, reducing the impact of fumes on the range hood, improving the stability of the integrated stove 10, and reducing the operating noise of the integrated stove 10.
[0048] See Figure 4 In some embodiments, along the transverse cross-section, the flow guiding structure 112 includes at least two flow guiding sections connected in sequence. The cavity walls of the flow guiding sections guide the oil fumes, causing them to flow along the cavity walls of the flow guiding sections and gather in the smoke collection chamber 111, and then continue to flow along the smoke collection chamber 111 to the flue. At the same time, the flow guiding sections create a certain resistance to the flow of oil fumes, thereby reducing the flow pressure of the oil fumes flowing along the smoke collection chamber 111 and further reducing the power consumption of the integrated stove 10.
[0049] It should be noted that, in this embodiment, there can be two guide segments, connected sequentially along the X direction. Alternatively, there can be three or more guide segments, connected sequentially along the X direction. This embodiment does not specify the number of guide segments. Furthermore, in this embodiment, the transverse cross-section is parallel to the horizontal plane.
[0050] In some implementations, the outlines of two adjacent guide sections are different to adjust the flow path of the fumes, making it easier for the fumes to gather after flowing along the guide sections.
[0051] For example, along the transverse cross-section, the outline shape of the guide section can be a straight line, a curve, or a combination of both, etc., and this application embodiment does not require this. In two adjacent guide sections, the outline shape of one guide section can be a straight line, and the outline shape of the other guide section can be a curve.
[0052] In some embodiments, the two ends of the flow guiding structure 112 are connected to the two sides of the air inlet 121, so that the fumes enter the smoke collection chamber 111 through the air inlet 121 and gradually gather under the guidance of the flow guiding structure 112 after entering the air inlet 121.
[0053] See Figure 4 In one specific embodiment, there are three guide sections, namely a first guide section 1121, a second guide section 1122 and a third guide section 1123. The first guide section 1121, the second guide section 1122 and the third guide section 1123 are connected sequentially along the X direction. One end of the first guide section 1121 is connected to the air inlet 121 and one end of the third guide section 1123 is connected to the air inlet 121.
[0054] In some implementations, at least two guide sections have curved profiles, and adjacent guide sections have different bending directions and different radii of curvature.
[0055] In the transverse cross section, the outlines of the first guide section 1121, the second guide section 1122, and the third guide section 1123 are all curves.
[0056] Specifically, the first guide section 1121 and the third guide section 1123 are bent relative to the air inlet 121 along the Y direction toward the air inlet 121, while the second guide section 1122 is bent relative to the air inlet 121 along the Y direction away from the air inlet 121. That is to say, the bending directions of the first guide section 1121 and the second guide section 1122 are different, and the bending directions of the second guide section 1122 and the third guide section 1123 are different.
[0057] See Figure 4 The curvature of the first guide section 1121 is greater than that of the second guide section 1122, and the curvature of the third guide section 1123 is greater than that of the second guide section 1122. That is, the radius of curvature of the second guide section 1122 is greater than that of the first guide section 1121 and the third guide section 1123, respectively.
[0058] This embodiment of the application uses such a flow guide structure 112 to control the flow path of the oil fumes, so as to guide the oil fumes and enable them to quickly gather. At the same time, the different bending directions and radii of curvature of adjacent flow guide sections help to break the turbulence formed by the oil fumes during flow, further reducing the impact of oil fumes on the smoke collection chamber 111, thereby reducing the operating noise of the head assembly 100 and the integrated stove 10.
[0059] In some embodiments, along the Y-direction from the front to the rear of the smoke collection chamber 111, the distance between the two sides of the guide structure 112 and the air inlet 121 is smaller than the distance between the guide structure 112 near the middle area and the air inlet 121. Thus, due to the smaller distance between the two sides of the guide structure 112 and the air inlet 121, the flow velocity of the oil fumes on both sides of the guide structure 112 increases, as does the air intake volume of the air inlet 121. Simultaneously, the oil fumes can be evenly distributed in the middle area of the guide structure 112 under its influence, reducing uneven flow of oil fumes and minimizing diffusion of oil fumes inside and outside the smoke collection chamber 111, thereby improving the efficiency and effectiveness of oil fume removal.
[0060] For example, see Figure 4 The first guide section 1121 and the third guide section 1123 are located on both sides of the second guide section 1122 along the X direction. The second guide section 1122 is located in the middle region of the guide structure 112 relative to the guide structure 112.
[0061] Along the Y direction, the distance between the first guide section 1121 and the air inlet 121 is less than the distance between the second guide section 1122 and the air inlet 121; the distance between the third guide section 1123 and the air inlet 121 is also less than the distance between the second guide section 1122 and the air inlet 121.
[0062] Along the X direction, the distance between the portion of the first guide section 1121 near the air inlet 121 and the air inlet 121 is less than the distance between the portion of the first guide section 1121 near the second guide section 1122 and the air inlet 121; the distance between the portion of the third guide section 1123 near the air inlet 121 and the air inlet 121 is less than the distance between the portion of the third guide section 1123 near the second guide section 1122 and the air inlet 121; the distance between the portion of the second guide section 1122 near the first guide section 1121 and the air inlet 121 is less than the distance between the central area of the second guide section 1122 near the guide structure 112 and the air inlet 121; the distance between the portion of the second guide section 1122 near the third guide section 1123 and the air inlet 121 is less than the distance between the central area of the second guide section 1122 near the guide structure 112 and the air inlet 121. In this way, the profile of the guide structure 112 in the cross-section forms a trumpet shape, which helps to gather the oil fumes.
[0063] In some embodiments, the smoke collection chamber 111 has a smoke gathering structure 113 on the side opposite to the air inlet 121. The smoke gathering structure 113 is connected to the smoke baffle 120 and forms a smoke gathering area 1131 between the smoke baffle 120 and the smoke collection chamber 111. The smoke gathering area 1131 is located between the air inlet 121 and the smoke collection chamber 111. The smoke gathering area 1131 can gather the oil fumes entering from the air inlet 121 and put them into the smoke collection chamber 111.
[0064] See Figure 5 Along the Y-direction, the smoke-collecting structure 113 is located on the side of the smoke baffle 120 facing away from the main body 300 of the stove. The smoke-collecting structure 113 is connected to the air inlet 121 and the smoke collection chamber 111 to form a flow path for oil fumes within the head assembly 100. The inner wall of the smoke-collecting structure 113 and the wall surface of the smoke baffle 120 facing the smoke-collecting structure 113 together form the smoke-collecting area 1131. Oil fumes enter the smoke-collecting area 1131 through the air inlet 121 and flow under the guidance of the inner wall of the smoke-collecting area 1131, forming a vortex to drive the oil fumes from the air inlet 121 into the smoke-collecting area 1131. At the same time, it can gather the oil fumes at various locations, so that the oil fumes can be relatively concentrated and then discharged through the smoke collection chamber 111 and the flue in sequence. In this way, the efficiency and effect of the head assembly 100 in absorbing oil fumes can be improved.
[0065] The cooking fumes enter the smoke collection area 1131 through the air inlet 121. Due to their high temperature, the fumes flow upwards and accumulate within the smoke collection area 1131. Simultaneously, they continuously flow along the inner wall of the smoke collection area 1131, forming a vortex to draw more fumes into the area, thus improving the smoke collection effect. In this embodiment, the combined action of the smoke collection structure 113 and the flow guiding structure 112 promotes the accumulation of cooking fumes, further enhancing the efficiency and effectiveness of fume removal.
[0066] In some embodiments, the lowest point of the smoke-collecting structure 113 is higher than the highest point of the air inlet 121. Alternatively, the lowest point of the smoke-collecting structure 113 is flush with the highest point of the air inlet 121. In this way, the smoke-collecting area 1131 formed by the smoke-collecting structure 113 can gather more oil fumes, further preventing the gathered oil fumes from flowing back through the air inlet 121, so that the gathered oil fumes are discharged as much as possible, improving the oil fume removal effect.
[0067] See Figure 5 Along the Z-direction, the lowest position of the smoke collection structure 113 can be the upper edge of the air inlet 121. Alternatively, the lowest position of the smoke collection structure 113 can be higher than the upper edge of the air inlet 121.
[0068] See Figure 5 In some embodiments, along the transverse section, the cross-sectional area of the smoke collection area 1131 is larger than the cross-sectional area of the smoke collection chamber 111 on the side near the air inlet 121.
[0069] In this embodiment, the transverse cross-section is parallel to the horizontal plane. The larger cross-sectional area of the smoke collection area 1131 can more effectively draw the oil fumes into the smoke collection area 1131 through the air inlet 121, and under the action of the flow guiding structure 112, the oil fumes will continue to flow and gather. In this way, the smoke collection structure 113 can collect more oil fumes, further improving the efficiency and effect of the head assembly 100 in removing oil fumes.
[0070] The cross-sectional area of the smoke collection chamber 111 near the air inlet 121 is relatively small. As the oil fumes flow along the air inlet 121, the smoke collection area 1131, and the smoke collection chamber 111, the flow area at each location is different. Furthermore, as the oil fumes flow from the smoke collection area 1131 to the smoke collection chamber 111, the cross-sectional area of the oil fume flow decreases, and the flow velocity of the oil fumes increases, thereby improving the efficiency and effectiveness of the head assembly 100 in removing oil fumes.
[0071] In some embodiments, the smoke-collecting structure 113 is a curved structure extending vertically, and the curved structure bends away from the air inlet 121. By setting the curved structure, the surface area of the smoke-collecting area 1131 is increased, meaning the overall space ratio of the smoke-collecting area 1131 is increased, allowing for the collection of more cooking fumes. Furthermore, the smoke-collecting area 1131, while collecting cooking fumes, also creates a certain resistance to the flow of cooking fumes, reducing the pressure of cooking fumes entering the smoke collection chamber 111, thereby reducing the impact of cooking fumes on the range hood and further reducing the noise of the integrated stove 10 during operation.
[0072] It should be noted that the curved surface structure in this embodiment is curved as a whole, and its surface can be uneven or smooth. This embodiment does not make specific requirements in this regard.
[0073] See Figure 5 In one specific embodiment, the smoke collection structure 113 is an arc-shaped curved surface structure extending vertically. The arc-shaped curved surface structure is easy to process. At the same time, the oil fumes condense on the arc-shaped curved surface, which is also easy for the user to clean. In this embodiment, the arc-shaped curved surface structure facilitates the flow of oil fumes, and the condensed oil fumes will flow along the arc-shaped curved surface to the bottom of the head assembly 100.
[0074] In some embodiments, the radius of curvature of the arc-shaped surface structure is 60-80 mm. For example, the radius of curvature of the arc-shaped surface structure can be 60 mm, 65 mm, 69 mm, 70 mm, 73 mm, 76 mm, 78 mm, 80 mm, etc. This application does not impose specific requirements on this.
[0075] Combination Figure 3 , Figure 4 and Figure 6 In this embodiment of the application, the smoke hood 110 includes a first hood 114 and a second hood 115. The first hood 114 and the second hood 115 together form a smoke collection cavity 111. The smoke gathering structure 113 is disposed on the second hood 115 and connected to the second hood 115. The second hood 115 is a planar structure.
[0076] It is easy to understand that the connection between the separately configured first cover 114 and second cover 115 forms the smoke collection chamber 111, facilitating the installation of the smoke collection hood 110. The second cover 115 is located along the Y-direction on the side opposite to the main cooktop 300, ensuring the integrated cooktop 10 fits snugly against the wall during installation, resulting in a smooth overall appearance for the smoke collection hood 110. Furthermore, the planar structure of the second cover 115 provides support for the connection to the smoke collection structure 113, offering good structural stability and strength, ensuring the entire smoke collection hood 110 remains stable and is not easily deformed during operation.
[0077] It should be noted that the second hood 115 and the smoke collection structure 113 are an integrated structure. Thus, the second hood 115 and the smoke collection structure 113 are a single, independent component, with no gaps between them, preventing oil fume leakage. This also reduces the number of connecting parts between the second hood 115 and the smoke collection structure 113, lowering the assembly difficulty of the smoke hood 110 and reducing production and installation time and costs.
[0078] In some implementations, see Figure 5 and Figure 6 The smoke-collecting structure 113 has a connecting portion 1132 at one end opposite to the second cover 115. The connecting portion 1132 bends toward the side opposite to the first cover 114 and is detachably connected to the smoke baffle 120. In this way, the connecting portion 1132 of the smoke-collecting structure 113 provides support and connection for the smoke baffle 120, thereby stabilizing the connection between the smoke baffle 120 and the smoke collection cover 110.
[0079] The head assembly 100 provided in this application embodiment includes: a smoke collection hood 110 and a smoke baffle 120 disposed above the smoke collection hood 110. The smoke collection hood 110 has a smoke collection chamber 111 extending in a vertical direction. The front side of the smoke baffle 120 has an air inlet 121 communicating with the smoke collection chamber 111. The smoke collection chamber 111 has a flow guiding structure 112 at a position opposite to the air inlet 121. The flow guiding structure 112 guides the oil fumes entering through the air inlet 121, and makes the oil fumes quickly and evenly gather in the smoke collection chamber 111 and then discharge them through the flue under the action of the negative pressure fan. In this way, the range hood can improve the oil fume removal efficiency and effect under the same power, and further reduce the power consumption of the range hood. During the flow of oil fumes, the guide structure 112 generates a certain flow resistance to the flow of oil fumes, further reducing the pressure of oil fumes before entering the air inlet 121 of the range hood, reducing the impact of oil fumes on the range hood, improving the stability of the integrated stove 10, and reducing the working noise of the integrated stove 10.
[0080] Additionally, see Figure 7 and Figure 8Researchers conducted fluid field analysis on the head assembly 100 without the flow guide structure 112 and the head assembly 100 with the flow guide structure 112, and obtained the following results: Under the same conditions, the head assembly 100 in this embodiment of the application has increased oil fume volume and improved oil fume extraction efficiency, and the performance of the head assembly 100 is better than that of the head assembly 100 without the flow guide structure 112. Meanwhile, through... Figure 7 and Figure 8 As can be seen, the oil fumes are more evenly distributed in the smoke collection chamber.
[0081] See Figure 9 and Figure 10 Researchers conducted fluid field analysis on the head assembly 100 without the smoke collection structure 113 and the head assembly 100 with the smoke collection structure 113, and obtained the following results: Under the same conditions, the amount of oil smoke in the head assembly 100 in this embodiment of the application increases, the oil smoke extraction efficiency is improved, and the performance of the head assembly 100 is better than that of the head assembly 100 without the smoke collection structure 113.
[0082] After measuring the oil fume pressure drop at the air inlet 121 and the bottom of the smoke collection chamber 111, the pressure drop of the head assembly 100 without the smoke collection structure 113 is 61.1 Pa, while the pressure drop of the head assembly 100 in this embodiment is 56.5 Pa. The reduced pressure drop of the head assembly 100 can reduce the energy consumption of the integrated stove 10 and improve the overall performance of the integrated stove 10.
[0083] In addition, this application embodiment may also provide an integrated stove 10, including the head unit 100 in any of the above embodiments.
[0084] The integrated stove 10 in this embodiment includes the head assembly 100 in the aforementioned embodiments, which improves the efficiency and effect of oil fume extraction.
[0085] 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.
[0086] 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.
[0087] 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 something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).
[0088] 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.
[0089] 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.
