Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, specifically to a fan support column and a fan. Background Technology

[0002] The support column of an electric fan is typically manufactured using a single-piece injection molding process. However, due to limitations in the mold's demolding angle, the support column must be divided into two independent parts, which are then assembled and fixed together via a snap-fit ​​method. However, in existing technology, there are noticeable installation gaps and seams at the connection point between the two parts, affecting the overall aesthetics of the product. Furthermore, dust easily accumulates in these gaps after prolonged use, making cleaning difficult. Some products have attempted to conceal the installation gaps and seams by molding the support column into a single piece, but this method presents challenges such as difficult maintenance, inconvenient demolding, and large transport volume. Utility Model Content

[0003] In view of this, the present invention provides a fan support column and a fan to solve the problem that the assembly gap of the assembled fan support column in the prior art is exposed, which easily accumulates dust and affects the overall aesthetics of the product.

[0004] In a first aspect, this utility model provides a fan support column, comprising:

[0005] The main body is connected between the fan head and the base, and an opening is provided on the upper side of the main body near the fan head;

[0006] The mating parts are detachably installed at the opening;

[0007] The fan head has a clearance portion at the position of the mating component. The clearance portion can accommodate the mating component and block at least part of the assembly gap between the mating component and the main body component.

[0008] Beneficial effects: This application disseminates the fan support column into two independent parts: a main body component and a mating component. The main body component serves as the primary load-bearing element, supporting and connecting the fan head and the base. The mating component provides auxiliary support and is detachably installed at the opening of the fan support column. The mating component facilitates demolding and maintenance of the fan support column mold. The disassembly of the main body component and mating component is not even; instead, the portion of the fan support column near the fan head is designated as the mating component, while the remaining portion remains as the main body component. A clearance portion on the fan head accommodates the mating component and at least partially conceals the assembly. The gap allows the side splitting points to be completely concealed within the fan head, avoiding or reducing the exposure of assembly gaps between the main body and mating components. Structurally, this hides the mating components within the clearance section of the fan head. Visually, the final assembled fan product is almost invisible from the main view, with only a small portion of the mating components visible from the side view. This significantly improves the product's aesthetics and effectively solves the problem in existing technologies where the assembly gaps of the assembled fan support columns are exposed, easily accumulating dust and affecting the overall appearance of the product.

[0009] In one alternative embodiment, the length of the opening is less than the length of the main component, and the mating component is a cover structure that snaps onto the opening, and the length of the mating component is less than the length of the main component.

[0010] Beneficial effects: The mating component adopts a cover structure design that snaps onto the opening, which is convenient for disassembly and assembly. Moreover, the length of both the opening and the mating component is less than the length of the main component, which makes it easy to hide the mating component and the assembly part between the mating component and the main component.

[0011] In one alternative embodiment, the clearance portion is formed by an inward recess from the fan head, and the width of the clearance portion is greater than the width of the mating component.

[0012] Beneficial effects: The clearance part adopts a design formed by the inward indentation of the fan head, which has a simple structure and is easy to process and form. The width of the clearance part is greater than the width of the mating part, ensuring that the mating part can be embedded in the clearance part.

[0013] In one alternative embodiment, the clearance portion is a groove structure formed on the rear grille of the fan, and the mating component is an arc-shaped cover structure that matches the curvature of the rear grille.

[0014] Beneficial effects: The rear grille of the fan is recessed inward towards the fan blades at the position corresponding to the mating parts, thereby creating space to accommodate the mating parts. The mating parts are designed as an arc-shaped cover structure with the same curvature as the rear grille, which allows the mating parts and the clearance parts to fit more closely, thereby improving the compatibility between the fan support column and the fan head and increasing the overall aesthetics of the machine.

[0015] In one optional embodiment, the wall thickness of the main component is d1, and the wall thickness of the mating component is d2, where 20% ≤ (d1-d2) / d2 ≤ 60%.

[0016] Beneficial effects: By adopting the above-mentioned thickness ratio design for the main body and mating parts, the strength of the main body can be increased, ensuring the stability of the whole machine.

[0017] In one optional embodiment, the mating component and the main body component enclose each other to form a wiring channel through which the connection line between the fan head and the base can pass. The upper end of the mating component is provided with a wire hole for the connection line to extend out, and the clearance part is provided with a clearance opening corresponding to the wire hole.

[0018] Beneficial effects: The wire-passing holes facilitate the connection of wires through the wiring channel to the motor inside the fan head, avoiding wire compression during assembly. Furthermore, by placing the wire-passing holes on the mating components and at the top of the components, the wires can directly enter the fan head through the clearance opening of the clearance part after exiting the wire-passing holes, without being exposed. The concealment of the wires further improves the overall aesthetics and effectively avoids the safety hazards associated with exposed wires.

[0019] In one alternative implementation, the mating component is snapped into and fixed to the main component.

[0020] Beneficial effects: The main components of the mating parts are fixed together by snap-fit, which can be used to assemble and disassemble them without the need for auxiliary tools, making it convenient and quick.

[0021] In one optional embodiment, the mating component is provided with snap-fit ​​fixing parts on both sides, and the main body component is provided with corresponding snap-fit ​​mating parts on both sides.

[0022] There are multiple snap-fit ​​fixing parts, which are spaced apart along the length of the mating parts. There are multiple snap-fit ​​mating parts, and the multiple snap-fit ​​mating parts are snap-fitted into each other in a one-to-one correspondence with the multiple snap-fit ​​fixing parts.

[0023] Beneficial effects: By providing corresponding snap-fit ​​fixing parts and snap-fit ​​mating parts on both sides of the mating parts and the main body, the fixing effect is better than that of a single-sided arrangement. Furthermore, by adopting a design that provides multiple snap-fit ​​fixing parts and snap-fit ​​mating parts at intervals along the length direction, the stability of the entire fan support column structure after assembly can be further improved.

[0024] In one optional embodiment, a positioning part is provided on the mating component, and a corresponding positioning mating part is provided on the main body component, wherein the positioning part and the positioning mating part are positioned and limited together.

[0025] Beneficial effects: By providing corresponding positioning parts and positioning mating parts on the mating parts and the main body, pre-positioning can be achieved during assembly, allowing the snap-fit ​​fixing parts and snap-fit ​​mating parts to accurately align, further improving the assembly efficiency of the mating parts and the main body and reducing the assembly difficulty.

[0026] In one optional embodiment, the positioning part is a hook plate disposed at the lower end of the mating component, and the positioning mating part is a rib structure that positions and mates with the hook plate.

[0027] Beneficial effects: The positioning part and the positioning mating part adopt a structure of hook plate and rib, which is simple in structure and easy to process and form.

[0028] In one alternative embodiment, the lower end face of the mating component is constructed as a bevel with an opening that is a beveled cut. During assembly, the beveled surface of the mating component slides into the opening of the main component along the beveled cut at the bottom of the beveled cut.

[0029] Beneficial effects: The lower edge of the beveled cut is a beveled surface. During assembly, the beveled surface of the mating parts slides along this beveled surface to guide the mating parts into the opening of the main body part along the preset assembly direction, thereby improving assembly efficiency. Moreover, the design of the beveled surface can also meet the actual production needs and facilitate mold release.

[0030] Secondly, this utility model also provides a fan, including a fan head, a base, and a fan support column according to any of the above embodiments, wherein the fan support column is disposed between the fan head and the base.

[0031] Beneficial effects: The assembly structure between the main body and mating parts of the fan support column, as well as the cable hole, are hidden in the fan head. The assembly gap is limited to an area not visible from a vertical perspective, greatly reducing the exposed part of the assembly gap. Users can hardly see the assembly parts of the main body and mating parts from the outside, which greatly improves the overall aesthetics of the product and effectively avoids the problem of dust accumulation and inconvenience in cleaning caused by exposed assembly gaps, thus affecting the overall appearance of the machine.

[0056] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0057] The following is combined Figures 1 to 14 The following describes embodiments of the present invention.

[0058] According to an embodiment of the present invention, in one aspect, the present invention provides a fan support column 10, including a main body component 11 and a mating component 12: the main body component 11 is connected between a fan head 20 and a base 30, and an opening is provided on the upper side of the main body component 11 near the fan head 20; the mating component 12 is detachably installed at the opening; the fan head 20 is provided with a clearance portion 201 corresponding to the position of the mating component 12, the clearance portion 201 can accommodate the mating component 12 and block at least part of the assembly gap between the mating component 12 and the main body component 11.

[0059] The above embodiment provides a concealed design for the fan support column, which is divided into two independent parts: a main component 11 and a mating component 12. The main component 11 serves as the primary load-bearing element, supporting and connecting the fan head 20 and the base 30. The mating component 12 provides auxiliary support and is detachably installed at the opening of the fan support column 10. The mating component 12 facilitates demolding and disassembly / maintenance of the fan support column 10. The separation of the main component 11 and the mating component 12 in this application is not an equal division, but rather a partial division of the fan support column 10... The portion near the fan head 20 above the 0 is divided into a mating component 12, while the remaining portion is the main body component 11. A clearance portion 201 provided on the fan head 20 can accommodate the mating component 12 and conceal the assembly gap between the mating component 12 and the main body component 11. This ensures that the entire side splitting point is contained within the fan head 20, minimizing or avoiding exposure of the assembly gap between the main body component 11 and the mating component 12. Structurally, this hides the mating component 12 within the clearance portion of the fan head. Visually, the final assembled fan product, from the main viewing angle (i.e.,...),... Figure 2 From the perspective of the main body, the mating parts and the assembly points between the mating parts and the main body are almost invisible. From the side view (i.e., Figure 3 From the perspective of the camera, only a small portion of the mating parts can be seen, which greatly improves the aesthetics of the product and effectively solves the problem that the assembly gap of the fan support column 10 formed by assembly in the prior art is exposed, which easily accumulates dust and affects the overall aesthetics of the product.

[0060] In some embodiments, combined with Figure 7 , Figure 8 , Figure 11 , Figure 12 As shown, the length of the opening is less than the length of the main component 11, and the mating component 12 is a cover structure that is fastened to the opening, and the length of the mating component 12 is less than the length of the main component 11.

[0061] In the above embodiments, the mating component 12 adopts a cover structure design that snaps onto the opening, which is convenient for disassembly and assembly. Furthermore, the lengths of both the opening and the mating component are less than the length of the main component, which facilitates the concealment of the mating component and the assembly part between the mating component and the main component.

[0062] Specifically, in combination Figure 9 , Figure 11 , Figure 12 The main body component 11 has an opening on its top side for mounting the mating component 12. The length of the mating component 12 is the same as the length of the opening. Figure 12 L1 represents the opening length. The opening is located in the upper half of the main body component 11. The opening is a strip-shaped opening, and the length of the opening is less than the length of the main body component 11. The length of the mating component 12 is less than the length of the main body component 11. Preferably, the length of the opening is less than two-thirds of the length of the main body component 11, and the length of the mating component 12 is less than two-thirds of the length of the main body component 11.

[0063] More preferably, the length of the opening is less than half the length of the main body 11, and the length of the mating part 12 is less than half the length of the main body 11.

[0064] Furthermore, the main body component 11 is divided into two parts by an opening. The upper part with the opening is a semi-cylindrical structure with a U-shaped or C-shaped cross-section, while the lower part without the opening is a circumferentially closed cylindrical structure. The main body component 11 is integrally injection molded. After the mating component 12 is installed at the opening of the main body component 11, it can form a circumferentially closed wiring channel with the main body component 11, which allows the connection lines between the fan head 20 and the base 30 to pass through. The opening on the main body component 11 is located on the front side, that is, the side facing the fan head 20. The mating component 12 is installed on the front side of the main body component 11, and the mating component 12 and the main body component 11 are arranged front and rear, with the assembly gap between the mating component 12 and the main body component 11 located on the left and right sides.

[0065] It should be noted that in this embodiment, the mating component 12 and the main body component 11 can be fixed by snap-fit ​​or bolts for easy assembly and disassembly. Currently, most products on the market have their support columns divided into two parts: a front support column and a rear support column. In this way, the assembly gap between the two parts is inevitably exposed. This application designs the front support column (matting component 12) as a small part, and the rear support column (main body component 11) as the main support component. The mating component 12 is equivalent to a cover for the side opening of the main body component 11. Through the above design, the mating component 12 can be hidden, avoiding or reducing the exposure of the mating gap between the mating component 12 and the main body component 11, and improving the overall aesthetics.

[0066] Furthermore, combined Figure 1 , Figures 3 to 8 As shown, the clearance part 201 has a receiving space for accommodating the mating component 12. The clearance part 201 can be formed by the recess of the fan head 20 or by the notch of the fan head 20. After the whole machine is assembled, the mating component 12 is embedded in the receiving part to achieve concealment. The two sides of the clearance part 201 can block the assembly gap between the mating component 12 and the two sides of the main body component 11.

[0067] In some embodiments, the clearance portion 201 is formed by an inward recess from the fan head 20; the width of the clearance portion 201 is greater than the width of the mating member 12, and the projection of the mating member 12 in the depth direction of the clearance portion 201 falls within the clearance portion 201. Figure 7 The direction indicated by the middle arrow W is the width direction of the avoidance part 201, the direction indicated by the arrow D is the depth direction of the avoidance part 201, and the direction indicated by the arrow L is the length direction of the avoidance part 201.

[0068] In the above embodiment, the clearance part 201 adopts a groove structure design formed by the inward recess of the fan head 20. The structure is simple and easy to process and form. The groove width of the clearance part 201 is greater than the width of the mating part 12, ensuring that the mating part 12 can be embedded in the clearance part 201. The projection of the mating part 12 in the depth direction of the clearance part 201 falls in the clearance part 201, ensuring that the clearance part 201 can block the assembly gap between the mating part 12 and the main body part 11.

[0069] In some embodiments, the clearance portion 201 is a groove structure formed on the rear grille 21 of the fan; the mating component 12 is an arc-shaped cover structure that matches the curvature of the rear grille 21, and the length of the clearance portion 201 matches the length of the mating component 12.

[0070] In the above embodiment, the position of the rear grille 21 of the fan corresponding to the mating component 12 is recessed towards the fan blade 26, thereby creating space to accommodate the mating component 12. The mating component 12 is set as an arc-shaped cover structure with the same curvature as the rear grille 21, which makes the mating component 12 fit more closely with the clearance part 201, thereby improving the compatibility between the fan support column 10 and the fan head 20 and increasing the overall aesthetics of the machine.

[0071] In some preferred embodiments, the length of the clearance portion 201 is the same as or greater than the length of the mating component 12, and the clearance portion 201 covers all the assembly gaps between the mating component 12 and the main body component 11. Of course, depending on the actual assembly requirements, the length of the clearance portion 201 can also be set to be slightly less than the length of the mating component 12, and the clearance portion 201 can cover most of the assembly gaps. This embodiment does not specifically limit this.

[0072] In some embodiments, such as Figure 9 , Figure 11 , Figure 14 As shown, the upper end of the mating component 12 is provided with a wire hole 123 for the connection line to extend out, and the clearance part 201 is provided with a clearance opening corresponding to the wire hole 123.

[0073] In the above embodiment, the wire through hole 123 facilitates the connection of the wires through the wiring channel to connect with the motor 23 inside the fan head 20, avoiding wire compression during assembly. Furthermore, by setting the wire through hole 123 on the mating component 12 and at the upper end of the mating component 12, the connection wires can directly enter the fan head 20 through the clearance opening of the clearance part 201 after exiting the wire through hole 123, without being exposed. The concealment of the wires can further improve the overall aesthetics, and at the same time effectively avoid the related safety hazards caused by exposed wires.

[0074] Specifically, in this embodiment, the fan head 20 includes a front grille 22, a rear grille 21, a motor assembly, and a fan blade 26. The motor assembly and fan blade 26 are disposed within the installation space enclosed by the front grille 22 and the rear grille 21. The motor assembly includes a motor 23 and a motor housing. The motor housing includes a motor cover 25 disposed on the front side of the motor 23 and a motor cover 24 disposed on the rear side of the motor 23. The motor cover 25 and the motor cover 24 are detachably connected to enclose an installation space for mounting the motor 23. A clearance structure is also provided on the motor cover 24 at the position corresponding to the clearance part 201. A controller board is disposed inside the base 30. The connection line includes a wire connecting the controller board and the motor 23. The wire passes through the wiring channel inside the main body component 11 and the mating component 12, and then extends out from the wire hole 123 on the mating component 12 to connect with the motor 23.

[0075] In some preferred embodiments, the mating component 12 and the main body component 11 enclose a wiring channel through which the connection line between the fan head 20 and the base 30 can pass. The wire hole 123 is an opening slot opened on the upper edge of the mating component 12. Compared with the conventional circular hole, the opening slot design of the wire hole 123 makes it easier for the wire to be inserted into or removed from the mating component 12.

[0076] In some embodiments, the mating component 12 is snapped together with the main component 11.

[0077] In the above embodiments, the main components 11 of the mating component 12 are fixed together by a snap-fit ​​method, which can achieve the assembly and disassembly of the two without the need for auxiliary tools, which is convenient and quick.

[0078] In some embodiments, such as Figures 11 to 14As shown, the mating component 12 is provided with snap-fit ​​fixing parts 121 on both sides, and the main body component 11 is provided with snap-fit ​​mating parts 111 on both sides. There are multiple snap-fit ​​fixing parts 121, which are spaced apart along the length direction of the mating component 12. There are multiple snap-fit ​​mating parts 111, and the multiple snap-fit ​​mating parts 111 are snap-fit ​​mated with the multiple snap-fit ​​fixing parts 121 in a one-to-one manner.

[0079] In the above embodiments, the snap-fit ​​fixing part 121 and snap-fit ​​mating part 111 provided on both sides of the mating part 12 and the main part 11 respectively have a better fixing effect than a single-sided arrangement. Furthermore, by adopting a design in which multiple snap-fit ​​fixing parts 121 and snap-fit ​​mating parts 111 are arranged at intervals along the length direction, the stability of the entire fan support column 10 structure after assembly can be further improved.

[0080] In some specific embodiments, the snap-fit ​​fixing part 121 and the snap-fit ​​mating part 111 are respectively represented by a snap fastener and a slot. Of course, in other alternative embodiments, the snap-fit ​​fixing part 121 and the snap-fit ​​mating part 111 can also be represented by a claw and a snap-fit ​​rib, etc. In the accompanying drawings of this embodiment, the snap-fit ​​fixing part 121 is shown as a snap fastener and the snap-fit ​​mating part 111 is shown as a slot.

[0081] In some specific embodiments, the mating component 12 includes a strip-shaped main body. The two sides of the strip-shaped main body are bent and extended towards the main body component 11 to form flanges. Multiple buckles are provided at intervals on the inner side of the flanges. Two fastening edges are provided on both sides of the opening of the main body component 11. Multiple slots are provided at intervals on the fastening edges. During assembly, the two flanges on both sides of the mating component 12 are pressed and fastened on the two fastening edges. The buckles on the flanges are engaged in the slots of the fastening edges, thereby fixing the mating component 12 to the main body component 11.

[0082] In some embodiments, the mating component 12 is provided with a positioning part 122, and the main body component 11 is provided with a corresponding positioning mating part 112, and the positioning part 122 and the positioning mating part 112 are positioned and limited together.

[0083] In the above embodiments, by providing positioning parts 122 and positioning mating parts 112 on mating parts 12 and main body parts 11 respectively, during assembly, positioning parts 122 and positioning mating parts 112 can be pre-positioned so that snap-fit ​​fixing parts 121 and snap-fit ​​mating parts 111 can be accurately connected, thereby improving the assembly efficiency of mating parts 12 and main body parts 11 and reducing assembly difficulty.

[0084] For example, the positioning part 122 and the positioning mating part 112 are connected by insertion positioning mating and hook positioning mating.

[0085] In some specific embodiments, the positioning part 122 is a hook plate provided at the lower end of the mating part 12, and the positioning mating part 112 is a rib structure that positions and mates with the hook plate.

[0086] In the above embodiments, the positioning part 122 and the positioning mating part 112 adopt a structure of hook plate and rib, which is simple in structure and easy to process and form.

[0087] Specifically, the hook plate is set on the lower inner side of the mating component 12. Optionally, the hook plate is formed by bending the bottom edge of the mating component 12 inward. During assembly, the hook plate at the lower end of the mating component 12 is first hooked onto the rib structure of the main body component 11 for pre-positioning, and then the mating component 12 is fastened onto the main body component 11 as a whole to achieve fixation.

[0088] Furthermore, the rib structure is a strip-shaped rib along the length of the main component 11. The length of the strip-shaped rib matches the length of the opening. The rib structure includes a hook portion 1121 and a reinforcing portion 1122. The hook portion 1121 is used to engage with the hook plate, and the reinforcing portion 1122 is used to increase the strength of the main component 11. Specifically, the hook portion 1121 is constructed as a longitudinal plate-like structure, and the reinforcing portion 1122 is a strip-shaped reinforcing rib. The height of the hook portion 1121 is greater than the height of the reinforcing portion 1122 to facilitate engagement with the hook plate. Figure 12 As shown, the height of the reinforcing part 1122 is H2, and the height of the hook part 1121 is H1, where H1 > H2.

[0089] Preferably, the hook plate is an inclined hook plate, and the angle between the hook plate and the strip body of the mating component 12 is less than 90°. The rib structure has an inclined hook edge that engages with the hook plate. The mating component 12 and the main body component 11 engage with the hook plate, which facilitates hooking and provides better anti-detachment effect.

[0090] More preferably, the rib structure has two ribs, and the two rib structures are spaced apart along the width direction of the opening. By setting two rib structures, the stability of the hook can be improved on the one hand, and the structural strength of the main component 11 can be further enhanced on the other hand.

[0091] In some embodiments, such as Figures 10 to 14 As shown, the lower end face of the mating component 12 is constructed as a bevel 120 with an opening that is a bevel. During assembly, the bevel 120 of the mating component 12 slides into the opening of the main component 11 along the bevel 110 at the bottom of the bevel.

[0092] In the above embodiment, the lower edge of the bevel is a bevel surface 110. During assembly, the bevel surface 120 of the mating component 12 slides along the bevel surface 110 to guide the mating component 12 to slide into the opening of the main component 11 along the preset assembly direction, thereby improving assembly efficiency. Moreover, the design of the bevel surface 110 can also meet the actual production needs and facilitate mold demolding.

[0093] Specifically, the lower edge of the strip-shaped main body of the mating component 12 and the bottom surface of the hook plate are both inclined to form a slope 120, and the bottom of the opening is a beveled surface 110.

[0094] In some embodiments, the wall thickness of the main component is d1, and the wall thickness of the mating component is d2, where 20% ≤ (d1-d2) / d2 ≤ 60%. By adopting the above-mentioned thickness ratio design for the main component and the mating component, the strength of the main component can be increased, ensuring the stability of the entire machine.

[0095] In this embodiment, the fan support column 10 is not divided evenly. Instead, a small portion near the fan head 20 is divided into mating parts 12, while the remaining portion forms the main body 11. Furthermore, the side splitting points are all located within the fan head 20 as much as possible, significantly reducing the problem of exposed mating gaps. Since the main body 11 serves as the primary load-bearing component, supporting the connection between the fan head 20 and the base 30, its strength must be ensured. Therefore, in this embodiment, the main body 11 is 20%-60% thicker than the mating parts 12, and is reinforced internally with reinforcing ribs. Preferably, the main body 11 is 40% thicker than the mating parts 12.

[0096] In some embodiments, in order to make the support column match and fit the fan head so that the assembly gap between the main body component and the mating component is hidden inside the fan head, the support column in this embodiment is set to a backward-inclined arc shape, and the inclination angle of the support column is less than 30°, so as to avoid the problem of unstable center of gravity and easy tipping due to the excessive inclination angle of the support column.

[0097] In some embodiments, the weight of the fan head 20 is 900g ± 10g to avoid the fan tipping backward due to excessive weight. The tilt angle of the fan head 20 does not exceed 45°, which further reduces the risk of the fan tipping backward.

[0098] According to an embodiment of the present invention, in another aspect, a fan is provided, including a fan head 20, a base 30, and a fan support column 10 of any of the above embodiments, wherein the fan support column 10 is disposed between the fan head 20 and the base 30.

[0099] In this embodiment, the assembly structure between the main body component 11 and the mating component 12 of the fan support column 10, as well as the wire hole 123, are hidden in the fan head 20. The assembly gap is limited to an area not visible from a vertical viewing angle, which greatly reduces the exposed part of the assembly gap. Users can hardly see the assembly part of the main body component 11 and the mating component 12 from the front and side, which greatly improves the overall aesthetics of the product and effectively avoids the problem of dust accumulation and inconvenience in cleaning caused by exposed assembly gaps, which affects the overall aesthetics of the machine.

[0100] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
