Description

Technical Field

[0001] The utility model belongs to daily necessities, and relates to a comb for combing hair and massaging skin, in particular to a building block combined comb. Background Art

[0002] For a long time, combs used for hair and body massage have been made from a single piece of wood or multiple pieces of wood with interwoven textures. These combs maintain their integrity and cannot be replaced. If any of the teeth break, they must be discarded.

[0003] In order to solve the technical problem of non-interchangeable combinations of traditional plate-like combs and improve the flexibility of combs in use, the industry has developed various combs similar to building block combinations, such as the technology disclosed in the Chinese patent document named "Comb", publication number CN 101803820 B, publication date May 15, 2013, and the technology named "A Comb", publication number CN102525083 B, publication date August 19, 2015.

[0004] For example, the technology disclosed in publication number CN 101803820 B utilizes a cross-shaped first connector and multiple T-shaped second connectors, with adjacent connectors sequentially plugged in to connect the comb teeth in series. This technology involves numerous connectors, resulting in a complex overall structure and cumbersome assembly. Furthermore, because the connectors serve as raised sections separating adjacent comb teeth, they create gaps between adjacent teeth. Consequently, the resulting comb structure contains numerous gaps running along the combing direction, making it prone to hair entrapment during combing, impacting normal use.

[0005] For example, the technology in publication number CN 102525083 B connects adjacent comb teeth and the partitions arranged between them into a single unit using a connecting shaft and a positioning shaft, solving the technical problems of looseness and deformation associated with the technology in publication number CN 101803820 B. However, this technology still suffers from the excessive number of separate partitions (i.e., spacers), which complicates the overall molding structure and makes assembly cumbersome. It also suffers from the problem of gaps between the partitions and adjacent comb teeth, which can trap hair. Utility Model Content

[0006] The technical purpose of the present utility model is to provide a modular comb with a regular and simple structure that is conducive to eliminating the gaps along the combing direction of the comb teeth, in view of the particularity of the above-mentioned replaceable combined plate comb and the shortcomings of the existing technology.

[0007] The technical purpose of the utility model is achieved through the following technical solution: a building block combined comb, having at least two independent comb tooth units, each comb tooth unit having at least one comb tooth;

[0008] Each comb tooth unit is connected at a set comb beam position to form a comb;

[0009] At the joint portion of the comb beams of two adjacent comb tooth units, a concave plugging groove is provided on the joint end surface of one comb tooth unit, and a convex plugging protrusion is provided on the joint end surface of the other comb tooth unit, and only a single plugging groove and / or plugging protrusion is provided on the same comb tooth unit;

[0010] Two adjacent comb tooth units are formed into a whole by inserting the concave-convex plug-in protrusions on the butt end surfaces into the plug-in grooves, and the exposed parts of the plug-in protrusions that are not fully inserted constitute the tooth gap separation structure between the adjacent comb tooth units.

[0011] Furthermore, the comb tooth unit is a single tooth structure;

[0012] The comb composed of the comb tooth unit has auxiliary teeth 1 and 2 at both ends, and a plurality of main teeth between the auxiliary teeth 1 and 2.

[0013] One end of the main tooth has a concave plug-in groove on its butt joint surface, and a convex plug-in protrusion on its other end. Two adjacent main teeth are assembled as a whole by inserting the concave and convex plug-in protrusions on the butt joint surface into the plug-in groove. The exposed portion of the plug-in protrusion in the current position that is not fully inserted constitutes a tooth gap separating structure between adjacent main teeth.

[0014] The mating end face of the auxiliary tooth 1 has an inserting groove with an inwardly concave structure. The auxiliary tooth 1 is assembled with the inserting protrusion of the adjacent main tooth through its own inserting groove. The inserting protrusion in the current position is not fully inserted and is exposed to form a tooth gap separation structure between the auxiliary tooth 1 and the adjacent main tooth;

[0015] The docking end face of the auxiliary tooth 2 is provided with an inserting protrusion with an external convex structure. The auxiliary tooth 2 is assembled together with the inserting groove of the adjacent main tooth through its own inserting protrusion. The inserting protrusion in the current position is exposed in the part that is not fully inserted, forming a tooth gap separation structure between the auxiliary tooth 2 and the adjacent main tooth.

[0016] As one of the preferred technical solutions, the plug-in groove has a plug-in limiting section and a plug-in countersunk section that are formed through-molded. The profile structure of the plug-in countersunk section is larger than the plug-in limiting section and covers the plug-in limiting section in the axial direction. The entire plug-in groove is a stepped structure.

[0017] The plug-in groove matches the inserted plug-in protrusion.

[0018] Furthermore, the surrounding contour of the plug-in limiting section is any one of a circular structure, an elliptical structure, a polygonal structure or an arc-shaped curved lace structure.

[0019] As one of the preferred technical solutions, the plug-in protrusion has an integrally formed tooth gap positioning section and a plug-in protrusion section. The profile structure of the tooth gap positioning section is larger than the plug-in protrusion section and covers the plug-in protrusion section in the axial direction. The entire plug-in protrusion is a stepped structure and matches the plug-in groove.

[0020] In the plug-in combination structure with the plug-in groove, the plug-in protrusion section is inserted into the plug-in limiting section of the plug-in groove, and the tooth gap positioning section adjacent to the end of the plug-in protrusion section is inserted into the plug-in countersunk section, and there is no combined gap along the comb teeth direction at each docking point.

[0021] Furthermore, the plug-in protrusion has at least one plug-in protrusion segment;

[0022] When there are multiple plug-in protrusion sections on the plug-in protrusion, they are spaced apart within the axial coverage range of the tooth gap positioning section;

[0023] Correspondingly, the plug-in limiting section in the plug-in groove matches each of the plug-in protrusion sections.

[0024] As one of the preferred technical solutions, the plug-in combination structure in which the plug-in protrusion is inserted into the plug-in groove is fixed into a whole in any one of a snap-fit ​​manner and a magnetic attraction manner.

[0025] As one of the preferred technical solutions, the comb tooth unit where the plug-in protrusion is located has a rod hole passing through the plug-in protrusion;

[0026] The comb tooth unit where the plug-in groove is located has a rod hole passing through the plug-in groove;

[0027] The plug-in combination structure is formed by plugging the plug-in protrusion into the plug-in groove to form a through-rod hole;

[0028] The combs are assembled into a whole and are locked in series by connecting ribs passed through the rod holes.

[0029] Furthermore, the connecting ribs are bolt structures.

[0030] Furthermore, the ends of the connecting ribs protrude from the auxiliary teeth at the corresponding ends, and the corresponding auxiliary teeth are connected to a head that covers the protruding ends of the connecting ribs;

[0031] Alternatively, the end of the connecting rib is hidden in the auxiliary tooth at the corresponding end.

[0032] The beneficial technical effect of the present invention is as follows: the above technical measures are aimed at the particularity of the above-mentioned replaceable and combined plate-like comb, and plug-in protrusions and plug-in grooves are formed on the comb tooth units except for a single auxiliary tooth, which are separated on the docking end faces on both sides, so that when adjacent comb tooth units are combined in series, the plug-in protrusions at the same docking position are inserted into the relative plug-in grooves to form a building block-type combined assembly structure, and the exposed portion of the plug-in protrusion that is not fully inserted into the plug-in groove forms a tooth gap separation structure - that is, a partition - between adjacent comb tooth units. It can be seen that in the above technical measures, the plug-in protrusions integrally formed on the corresponding comb tooth units not only assume the plug-in function but also the partition function between adjacent comb teeth, thereby simplifying the components constituting the entire comb, and the molding structure of each comb tooth unit is regularized, and further, during the assembly process of the entire comb, there is no need to be limited to the specific placement position of a certain comb tooth unit (except for the auxiliary teeth or the comb tooth unit containing auxiliary teeth), the assembly relationship is clear, and the assembly operation is simple and easy.

[0033] At the same time, in the above-mentioned technical measures, the plug-in protrusion, which functions as a plug, also takes on the function of partitioning. Therefore, the plug-in relationship between the plug-in protrusion and the corresponding plug-in groove forms an assembly structure with a countersunk head and a hidden gap (the gap refers to the gap along the combing direction of the comb teeth). As a result, the resulting comb has no joint gap along the combing direction of the comb teeth. This effectively eliminates the technical problem of hair entrapment during combing, which has always existed in the technologies of the above-mentioned publications No. 101803820 B and CN 102525083 B. This is particularly prominent in the matching structure of the stepped plug-in groove and the plug-in protrusion. Therefore, the comb of the above-mentioned technical measures can meet the technical requirements of flexible and interchangeable combinations without affecting normal use.

[0047] Although other embodiments are not separately drawn in the drawings, their main structures can still refer to the drawings of Example 1, Example 2, Example 5, Example 8, Example 9, Example 10, Example 11, Example 12, and Example 13.

[0048] It should be noted that the drawings of the present invention are schematic and have been simplified to clarify the technical objectives of the present invention, without necessarily obscuring the technical contribution of the present invention over the prior art. Furthermore, expressions such as "approximately" and "substantially" regarding quantities or fitting relationships below are intended to allow for reasonable assembly and processing errors within the industry, and do not literally represent absolute quantities or fitting relationships.

[0049] Example 1

[0050] See also Figure 1 、 Figure 2 and Figure 3 As shown, the utility model is a building block assembly comb having a plurality of independent comb tooth units, each comb tooth unit having one comb tooth, corresponding to the structure of a plate-shaped comb seen in daily life, and each comb tooth unit corresponds to the auxiliary tooth 1 and the auxiliary tooth 2 5 at both ends of the comb, and corresponds to each main tooth 2 between the auxiliary tooth 1 and the auxiliary tooth 2 5.

[0051] The root of each comb tooth serves as the comb beam position of the entire comb, and the middle and tip of the comb teeth serve as the combing area of ​​the entire comb. The independent comb teeth are connected at the set comb beam position to form a comb.

[0052] The plate-shaped comb is formed by the sequentially mating arrangement of the auxiliary tooth 1, each main tooth 2, and the auxiliary tooth 2 5. Thus, there are mating areas between the auxiliary tooth 1 and the adjacent main tooth 2, between adjacent main teeth 2, and between the auxiliary tooth 2 5 and the adjacent main tooth 2. Each main tooth 2 has a concave insertion groove 4 on one mating end surface and a convex insertion protrusion 3 on the other mating end surface. The mating end surface of the auxiliary tooth 1 has a concave insertion groove 4, and the mating end surface of the auxiliary tooth 2 5 has a convex insertion protrusion 3.

[0053] The insertion grooves 4 on each comb tooth have the same structure. They have a through-molded insertion stop section 41 and a countersunk insertion section 42. The countersunk insertion section 42 is larger than the insertion stop section 41 and axially overlaps it. The entire insertion groove 4 has a stepped structure. The insertion grooves mate with the inserted insertion protrusions.

[0054] In other words, the plug-in protrusion 3 comprises an integrally formed tooth gap positioning section 32 and a plug-in protrusion section 31. The tooth gap positioning section 32 is larger than the plug-in protrusion section 31 and axially overlaps the plug-in protrusion section 31. The entire plug-in protrusion 3 has a stepped structure and matches the inserted plug-in groove 4. In order for the plug-in protrusion 3 to form a tooth gap partition between adjacent comb teeth after completing the plugging function, the length of the plug-in protrusion 3 must be greater than the depth of the plug-in groove 4.

[0055] The comb teeth of the above structure are connected in a modular manner as follows:

[0056] Two adjacent main teeth 2 are formed into a whole by inserting the concave-convex plug-in protrusions 3 on the butt end surfaces into the plug-in grooves 4. The plug-in protrusion 3 at each plug-in position, where it is not fully inserted and is exposed (i.e., the tooth gap positioning section 32, the same below), forms a tooth gap separation structure between adjacent main teeth 2.

[0057] The mating end face of the auxiliary tooth 1 has an inwardly concave insertion groove 4. The auxiliary tooth 1 is assembled with the insertion protrusion 3 of the adjacent main tooth 2 through its own insertion groove 4. The insertion protrusion 3 in the current position is not fully inserted and is exposed, forming a tooth gap separation structure between the auxiliary tooth 1 and the adjacent main tooth 2.

[0058] The mating end face of the auxiliary tooth 2 5 has an integrated plug-in protrusion 3 with an external convex structure. The auxiliary tooth 2 5 is assembled together with the plug-in groove 4 of the adjacent main tooth 2 through its own plug-in protrusion 3. The plug-in protrusion 3 in the current position is exposed in the part that is not fully inserted to form a tooth gap separation structure between the auxiliary tooth 2 5 and the adjacent main tooth 2.

[0059] In the above-mentioned plug-in assembly structure of each comb tooth, in order to improve or eliminate the joining gap between the plug-in protrusion 3 and the inserted comb teeth, the tooth gap positioning section 32 of the plug-in protrusion 3 is close to the end of the plug-in protrusion section 31 and is inserted into the plug-in countersunk section 42 of the corresponding plug-in groove 4 in a countersunk manner. Therefore, the plug-in protrusion 3 forms a countersunk hidden seam assembly structure at the corresponding plug-in groove 4, and there is no combined gap along the direction of the comb teeth at each docking point, so that there is no phenomenon of hair being clamped during use.

[0060] As can be seen from the above structure, at the joint portion of the comb beams of two adjacent comb teeth, the mating end surface of one comb tooth has a concave insertion groove 4, and the mating end surface of the other comb tooth has a convex insertion protrusion 3. Furthermore, the same main tooth 2 has only a single insertion groove 4 and insertion protrusion 3, while the auxiliary tooth 1 2 has only a single insertion groove 4, and the auxiliary tooth 2 5 has only a single insertion protrusion 3. The two adjacent comb teeth are assembled together by inserting the concave and convex insertion protrusion 3 on the mating end surfaces into the insertion groove 4. The exposed portion of the insertion protrusion 3, which is not fully inserted, constitutes the tooth gap separating the adjacent comb teeth.

[0061] To prevent circumferential rotation of adjacent comb teeth during insertion and assembly, the surrounding contour of the insertion limit section 41 of the insertion groove 4 is formed with a non-circular structure, such as a rectangular structure, which is one of the polygonal structures. Of course, to increase the bonding surface between the insertion groove 4 and the insertion protrusion 3 and enhance the force, the surrounding contour of the insertion limit section 41 of the insertion groove 4 is formed with an arc-shaped lace structure, that is, an arc-shaped lace structure is formed on the basis of the main rectangular structure. Of course, the insertion protrusion 3 and the insertion groove 4 have a concave-convex matching structure, so the outer contour of the insertion protrusion 3 is consistent with that of the insertion groove 4.

[0062] In the above-mentioned plug-in combination structure of each comb tooth, in order to prevent the comb teeth that are plugged together from loosening at will, it is best to form an interference fit between the plug-in protrusions and the plug-in grooves that are plugged together, or to reinforce them with a snap combination or a magnetic combination.

[0063] Example 2

[0064] The rest of the content of this embodiment is the same as that of embodiment 1, except that (see Figure 4 shown):

[0065] A through-rod hole is provided between the bottom of the insertion groove on each main tooth 2 and the end of the insertion protrusion 3;

[0066] Similarly, there is a through-rod hole between the bottom and the outer side of the insertion groove of the auxiliary gear 1;

[0067] There is a through rod hole between the end of the plug-in protrusion 3 of the auxiliary tooth 2 5 and the outer side;

[0068] The rod holes between the comb teeth that are sequentially inserted and assembled are connected.

[0069] The comb, assembled into a single piece, is locked in series by connecting ribs 6 threaded through the rod holes. These ribs are bolted, with auxiliary teeth 1 and 2 5 protruding from their ends. Connecting ribs 6 are attached to the corresponding auxiliary teeth with caps that cover the protruding ends of the ribs 6. These caps have non-sharp edges, forming convex cones (or massage teeth) at the ends of the corresponding auxiliary teeth, which can massage acupuncture points. The end caps of the ribs 6 constitute the massage teeth.

[0070] Example 3

[0071] The other structures of this embodiment are the same as those of embodiment 2, except that:

[0072] The rod-penetrating holes formed on the auxiliary teeth 1 and 2 are respectively blind hole structures and not through-holes;

[0073] The end of the connecting rib is hidden in the auxiliary tooth at the corresponding end and does not emerge. As for the fastening structure of the end of the connecting rib in the corresponding auxiliary tooth, it can be assisted by a snap combination method or a magnetic combination method.

[0074] Example 4

[0075] The rest of this embodiment is the same as that of embodiment 2, except that:

[0076] Due to the locking connection relationship between the connecting ribs at both ends of the auxiliary teeth, the problem of relative looseness between the comb teeth basically does not exist, so the outer contours of the plug-in grooves and the plug-in protrusions can also adopt a circular structure.

[0077] Example 5

[0078] The rest of the content of this embodiment is the same as that of embodiment 1, except that (see Figure 5 shown):

[0079] The comb teeth that make up the comb are massage teeth, and the tooth tips have spherical crown-shaped massage heads, and the gaps between the comb teeth are relatively sparse.

[0080] Example 6

[0081] The rest of this embodiment is the same as that of embodiment 1, except that:

[0082] The outer contours of the plug-in groove and the plug-in protrusion adopt an elliptical structure.

[0083] Example 7

[0084] The rest of this embodiment is the same as that of Embodiment 1, 2, 3, 4, 5 or 6, except that:

[0085] There are two plug-in limit sections in the plug-in groove (of course, there can be other numbers) arranged at intervals, and are within the axial coverage range of the same plug-in countersunk section;

[0086] Correspondingly, there are two plug-in protrusion sections on the plug-in protrusion arranged at a distance, and the two plug-in protrusion sections are within the axial coverage range of the same tooth gap positioning section.

[0087] Example 8

[0088] See also Figure 6 As shown, the utility model is a building block assembly comb having a plurality of independent comb tooth units, each comb tooth unit having one comb tooth, corresponding to the structure of a plate-shaped comb seen in daily life, and each comb tooth unit corresponds to the auxiliary tooth 1 and the auxiliary tooth 2 5 at both ends of the comb, and corresponds to each main tooth 2 between the auxiliary tooth 1 and the auxiliary tooth 2 5.

[0089] The root of each comb tooth serves as the comb beam position of the entire comb, and the middle and tip of the comb teeth serve as the combing area of ​​the entire comb. The independent comb teeth are connected at the set comb beam position to form a comb.

[0090] The plate-shaped comb is formed by the sequential docking combination of the auxiliary tooth 1, each main tooth 2, and the auxiliary tooth 2 5. Therefore, there are docking locations between the auxiliary tooth 1 and the adjacent main tooth 2, between the adjacent main teeth 2, and between the auxiliary tooth 2 5 and the adjacent main tooth 2. Each main tooth 2 has a plug-in groove 4 with an inwardly concave structure on its docking end surface, and a plug-in protrusion 3 with an outwardly convex structure on its docking end surface. A through-rod hole is provided between the bottom of the plug-in groove 4 and the end of the plug-in protrusion 3 on the same main tooth 2. The docking end surface of the auxiliary tooth 1 has a plug-in groove with an inwardly concave structure, and a through-rod hole is provided between the bottom of the plug-in groove of the auxiliary tooth 1 and the outer side. The docking end surface of the auxiliary tooth 2 5 has a plug-in protrusion with an outwardly convex structure, and a through-rod hole is provided between the end of the plug-in protrusion of the auxiliary tooth 2 5 and the outer side.

[0091] The structure of the plug-in groove 4 on each comb tooth is identical. The plug-in groove 4 has a plug-in convex head section 31 for plugging in the matching plug-in protrusion 3, and the plug-in groove 4 is matched with the plug-in convex head section 31.

[0092] The plug-in protrusion 3 has an integrally formed tooth gap positioning section 32 and a plug-in protrusion section 31. The contour structure of the tooth gap positioning section 32 is larger than the plug-in protrusion section 31 and covers the plug-in protrusion section 31 in the axial direction. The entire plug-in protrusion 3 is a step structure, and the plug-in protrusion section 31 of the plug-in protrusion 3 matches the plug-in groove 4.

[0093] The comb teeth of the above structure are connected in a modular manner as follows:

[0094] Two adjacent main teeth 2 are formed into a whole by inserting the plug-in protrusion section 31 with a concave-convex fit on the butt end surface into the plug-in groove 4. The plug-in protrusion 3 at each plug-in position forms a tooth gap separation structure between adjacent main teeth 2 at the part that is not fully inserted (i.e., the tooth gap positioning section 32, the same below). The end surface of the tooth gap positioning section 32 abuts against the butt end surface of the main tooth 2 where the plug-in groove 4 is located, and the rod hole between the two adjacent main teeth 2 is connected.

[0095] The mating end face of the auxiliary tooth 1 has a recessed insertion groove 4. The auxiliary tooth 1 is assembled with the insertion protrusion section 31 of the adjacent main tooth 2 through its own insertion groove 4. The insertion protrusion 3 in the current position, which is not fully inserted and is exposed, forms a tooth gap separating structure between the auxiliary tooth 1 and the adjacent main tooth 2. The end face of the tooth gap positioning section 32 in the current position abuts against the mating end face of the auxiliary tooth 1, and the rod hole on the auxiliary tooth 1 is connected to the rod hole of the adjacent main tooth 2.

[0096] The butt-jointed end face of the auxiliary tooth 2 5 has an integrated plug-in protrusion 3 with an externally convex structure. The auxiliary tooth 2 5 is assembled and inserted into the plug-in groove 4 of the adjacent main tooth 2 through its own plug-in protrusion section 31. The plug-in protrusion 3 in the current position, which is not fully inserted and is exposed, forms a tooth gap separating structure between the auxiliary tooth 2 5 and the adjacent main tooth 2. The end face of the tooth gap positioning section 32 in the current position abuts against the butt-jointed end face of the adjacent main tooth 2, and the rod hole on the auxiliary tooth 2 5 is connected to the rod hole of the adjacent main tooth 2.

[0097] In the above-mentioned plug-in assembly structure of each comb tooth, the through-rod holes between the comb teeth that are plugged in and assembled together in sequence are connected; in order to improve the engagement gap between the end face of the tooth gap positioning section 32 of the plug-in protrusion 3 and the inserted comb teeth, the comb assembled into a whole is locked in series by the connecting rib 6 passed through the through-rod hole; the connecting rib 6 is a bolt structure, and the auxiliary tooth 1 and the auxiliary tooth 2 5 are correspondingly protruding from both ends. The connecting rib 6 is connected to the corresponding auxiliary tooth with a head covering the end of the connecting rib 6, and the head adopts a non-sharp edge structure, so that a convex cone (or massage tooth) that can massage acupuncture points is formed at the end of the corresponding auxiliary tooth of the entire comb, that is, the massage tooth is constituted by the end head of the connecting rib 6.

[0098] In the above-mentioned modular plug-in structure, the serial locking force of the connecting ribs 6 is used to improve the phenomenon of hair being stuck during use.

[0099] As can be seen from the above structure, at the joint portion of the comb beams of two adjacent comb teeth, the mating end surface of one comb tooth has a concave insertion groove 4, and the mating end surface of the other comb tooth has a convex insertion protrusion 3. Furthermore, the same main tooth 2 has only a single insertion groove 4 and insertion protrusion 3, while the auxiliary tooth 1 2 has only a single insertion groove 4, and the auxiliary tooth 2 5 has only a single insertion protrusion 3. The two adjacent comb teeth are assembled together by inserting the concave and convex insertion protrusion 3 on the mating end surfaces into the insertion groove 4. The exposed portion of the insertion protrusion 3, which is not fully inserted, constitutes the tooth gap separating the adjacent comb teeth.

[0100] To prevent circumferential rotation between adjacent teeth when inserted and assembled, the periphery of the insertion groove 4 is formed in a non-circular configuration, such as a rectangular configuration, which is a polygonal configuration. Of course, the insertion protrusion section 31 of the insertion protrusion 3 and the insertion groove 4 have a concave-convex matching structure, so the outer contour of the insertion protrusion section 31 of the insertion protrusion 3 is consistent with that of the insertion groove 4.

[0101] Example 9

[0102] The rest of the content of this embodiment is the same as that of embodiment 1, except that (see Figure 7 shown):

[0103] The teeth that make up the comb are massage teeth, the tips of the teeth have spherical crown-shaped massage heads, and the gaps between the teeth are relatively sparse;

[0104] The tooth gap positioning section of the plug-in protrusion is directly formed by the streamlined bending and convex shape of the contour of the comb tooth root.

[0116] The rest of the content of this embodiment is the same as that of embodiment 8, except that (see Figure 11 shown):

[0117] The middle part of each comb tooth serves as a butt joint to form the comb beam of the formed comb;

[0118] One side of the comb has dense teeth for combing hair, while the other side has sparse teeth for massaging. The structure of the entire comb is similar to a comb.

[0119] In the comb structure of this embodiment, if it is a comb with a massage function, one comb tooth unit corresponds to one comb tooth; if it is a combing function, one comb tooth unit corresponds to multiple comb teeth arranged at intervals.

[0120] The above embodiments are only used to illustrate the present invention, rather than to limit it.

[0121] Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the above embodiments or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the present invention.
