Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and particularly to a sliding door structure and a cabinet body. Background Art

[0002] A sliding door is characterized in that it realizes opening and closing by means of horizontal pushing and pulling, rather than the traditional inward or outward rotation. This design makes the space utilization more efficient and improves the utilization rate of the indoor space. Since the existing sliding doors are usually vertically arranged, the upper track, upper pulley, lower track and lower pulley of the sliding door will also be correspondingly vertically arranged. With the development of sliding door products, nowadays, not only vertically arranged sliding doors are needed, but also the demand for inclined sliding doors has emerged. However, the existing vertically arranged sliding doors cannot be directly well adapted to an inclined application environment.

[0052] Embodiment 1 - Sliding Door Structure

[0053] An embodiment of the present invention discloses a sliding door structure. The mentioned sliding door structure realizes opening and closing by means of horizontal pushing and pulling. For example, it may specifically include a door frame, a door leaf 1, a slide rail, and pulleys and other specific components. The door leaf 1 slides on the track through the pulleys to realize opening and closing. Moreover, in order to be well applied to an inclined environment, the structure of the sliding door in this application has been improved. And this sliding door structure can be specifically applied to a cabinet body or a building wall.

[0054] The following is combined with the attached Figures 1-11 to describe the sliding door structure of this application.

[0055] Since the existing sliding doors are usually vertically arranged and cannot be well directly adapted to an inclined application environment, one of the purposes of this application is to design a sliding door structure that can be well applied to an inclined application environment.

[0056] In a specific embodiment, this sliding door structure may specifically include:

[0057] Door assembly, including a door leaf 1, an upper frame 11 fixed to the top of the door leaf 1, and a lower frame 12 fixed to the bottom of the door leaf 1. An upper pulley assembly is provided at the upper frame 11, and a lower pulley assembly is provided at the lower frame 12. An upper track 2, the upper pulley assembly is slidably arranged with the upper track 2, and the upper track 2 and the upper pulley assembly are arranged vertically. A lower track 3, the lower pulley assembly is slidably arranged with the lower track 3, and the door leaf 1, the upper frame 11, the lower frame 12, and the lower pulley assembly are arranged obliquely. The upper pulley assembly includes an upper bracket 21 and an upper pulley 22 rotatably arranged with the upper bracket 21. The upper frame 11 is fixed with an upper connecting piece 13, and a rotating shaft 4 is arranged between the upper connecting piece 13 and the upper bracket 21 and can rotate relative to the rotating shaft 4 as the center. A fastening member is arranged between the upper connecting piece 13 and the upper bracket 21 to lock the upper connecting piece 13 and the upper bracket 21 in place after rotation.

[0058] In the sliding door structure of the present application, it can not only be well applied to inclined environments, but also be adapted to scenarios with multiple different inclined angles. The specific principle is as follows:

[0059] In the actual inclined application scenario, when assembling the sliding door structure of the present application, since the overall height of the actual sliding door is relatively determined, after determining the specific assembly positions of the upper track 2 and the lower track 3 in the sliding door structure of the present application, the inclined angle of the sliding door structure of the present application can be determined. Therefore, in actual assembly, the assembly positions of the upper track 2 and the lower track 3 can be determined according to the overall height of the sliding door, so that the sliding door structure of the present application can finally be placed obliquely.

[0060] Therefore, for different inclined application scenarios, different assembly positions of the upper track 2 and the lower track 3 can be determined, so that the inclined angles at which the sliding door structure of the present application can finally be placed obliquely are also different. In this regard, in order to be adapted to scenarios with multiple different inclined angles, through research and development and design, a rotating shaft 4 is arranged between the upper bracket 21 of the upper pulley assembly and the upper connecting piece 13 of the upper frame 11 of the door leaf 1 in the sliding door structure of the present application. By setting the rotating shaft 4, the upper connecting piece 13 and the upper bracket 21 can rotate relative to the rotating shaft 4 as the center, thereby adjusting the angle of the included angle between the upper connecting piece 13 and the upper bracket 21. Overall, it is equivalent to adjusting the overall inclined angle of the door leaf 1, the upper frame 11, the lower frame 12, and the lower pulley assembly. Therefore, the sliding door structure of the present application can be well adapted to scenarios with multiple different inclined angles.

[0061] It should be noted that after the upper connecting piece 13 and the upper bracket 21 rotate in place with the rotating shaft 4 as the center, a fastening member can be specifically used to lock the upper connecting piece 13 and the upper bracket 21 in place after rotation, so as to ensure that the preset inclined angle can be stably maintained and the overall structural stability can be improved.

[0062] In summary, the sliding door structure of the present application, by specifically setting the upper connecting member 13 and the upper bracket 21 that can rotate relative to each other and can be locked and fixed relative to each other, can not only be well applied to an inclined environment, but also be adapted to scenarios with multiple different inclined angles.

[0063] In a specific embodiment, the upper bracket 21 has an arcuate kidney-shaped through hole 51, and the upper connecting member 13 has an upper assembly through hole 52. The arcuate center of the kidney-shaped through hole 51 coincides with the center of relative rotation of the upper connecting member 13 and the upper bracket 21; the fastener includes a fixing bolt 61 and a fixing nut 62 threadedly connected to the fixing bolt 61. After the fastener passes through the kidney-shaped through hole 51 and the upper assembly through hole 52, it is locked with the fixing nut 62. In the sliding door structure of the present application, when it is necessary to adjust other different inclined angles, the fixing nut 62 can be loosened first. Due to the provision of the arcuate kidney-shaped through hole 51, the fixing bolt 61 can move within the kidney-shaped through hole 51, which is equivalent to forming an avoidance channel to prevent interference and jamming when the upper connecting member 13 and the upper bracket 21 rotate relative to each other. Moreover, the overall structure will be compact, and at the same time, it is also convenient to loosen the upper connecting member 13 and the upper bracket 21 for relative rotation, and to lock the upper connecting member 13 and the upper bracket 21.

[0064] Of course, in other embodiments, the connection structure between the upper connecting member 13 and the upper bracket 21 can also be, for example, the upper connecting member 13 has an arcuate kidney-shaped through hole 51, and the upper bracket 21 has an upper assembly through hole 52. The arcuate center of the kidney-shaped through hole 51 coincides with the center of relative rotation of the upper connecting member 13 and the upper bracket 21; the fastener includes a fixing bolt 61 and a fixing nut 62 threadedly connected to the fixing bolt 61. After the fastener passes through the kidney-shaped through hole 51 and the upper assembly through hole 52, it is locked with the fixing nut 62. The difference from the previous embodiment is that the positions of the kidney-shaped through hole 51 and the upper assembly through hole 52 are interchanged, and the locking function can also be achieved on the basis of preventing rotation jamming.

[0065] In a specific embodiment, the upper connecting member 13 and the upper bracket 21 each have a rotating through hole 53 and the two rotating through holes 53 are aligned for the detachable insertion of the rotating shaft 4. Such a setting facilitates the more rapid assembly of the rotating shaft 4 between the upper connecting member 13 and the upper bracket 21, improving the assembly efficiency.

[0066] More importantly, due to the specific use of the detachable rotating shaft 4 structure and the cooperating structure of the detachable fixing bolts 61 and fixing nuts 62, the upper connecting member 13 and the upper bracket 21 are specifically detachably connected. Such a setting aims to greatly facilitate the assembly of the sliding door structure of the present application. It can be seen that when assembly is required, other workpieces can be first assembled to appropriate positions. For example, the overall height of the sliding door structure of the present application is calculated in advance, and based on this overall height, the specific assembly positions of the upper track 2 and the lower track 3 are determined, and the upper track 2 and the lower track 3 are specifically assembled to appropriate positions on the cabinet body or the wall. The upper pulley assembly is specifically assembled into the upper track 2, and the lower pulley assembly is assembled into the lower frame 12. At this time, the door leaf 1 can be placed obliquely. First, the lower pulley 32 is specifically installed at the lower track 3. With the contact area between the lower pulley 32 and the lower track 3 as the rotation point, the door leaf 1 is rotated upward until the rotation through holes 53 of the upper connecting member 13 and the upper bracket 21 are aligned with each other. Then the rotating shaft 4 is assembled into the two rotation through holes 53, and finally the fixing nut 62 on the fixing bolt 61 is tightened to complete the assembly.

[0067] It should be noted that by using the above assembly method, after the upper track 2 and the lower track 3 are specifically assembled in place, in fact, the inclination angle of the door leaf 1 can be determined. At the same time, after the rotation through holes 53 of the upper connecting member 13 and the upper bracket 21, as well as the waist-shaped through holes 51 and the upper assembly through holes 52 are assembled in place, they will directly correspond and align with each other, so as to facilitate the assembly of the rotating shaft 4 and the fixing bolt 61, and can improve the overall assembly efficiency.

[0068] In a specific embodiment, the upper pulley assembly is specifically assembled in the upper track 2, that is, the upper bracket 21 and the upper pulley 22 are slidably arranged in the upper track 2, which effectively reduces the overall occupied space, makes the overall structure more compact, and at the same time the sliding is more smooth.

[0069] Specifically, the upper bracket 21 and the upper pulley 22 are slidably arranged in the upper track 2. The upper bracket 21 includes a transverse bracket section 211 and vertical bracket sections 212 fixed to both sides of the transverse bracket section 211. The upper pulley 22 is horizontally arranged and rotatably arranged on the transverse bracket section 211. The upper connecting member 13 includes a transverse connecting section 131 and vertical connecting sections 132 fixed to both sides of the transverse connecting section 131. A rotating shaft 4 and a fastener are arranged between one vertical bracket section 212 and one vertical connecting section 132. It should be noted that the transverse bracket section 211 extends along the pushing and pulling direction, and both sides of the transverse bracket section 211 refer to both sides along the pushing and pulling direction. The transverse connecting section 131 extends along the pushing and pulling direction, and both sides of the transverse connecting section 131 refer to both sides along the pushing and pulling direction. With such an arrangement, the overall shape of the upper bracket 21 will specifically be in a concave shape, and the overall shape of the upper connecting member 13 will also specifically be in a concave shape. After assembling the upper bracket 21 and the upper connecting member 13 together, an assembly space for the upper pulley 22 will be formed between the upper bracket 21 and the upper connecting member 13, making the structure more compact.

[0070] Specifically, one vertical connecting section 132 has a kidney-shaped through hole 51 in an arc shape, and one vertical bracket section 212 has an upper assembly through hole 52. The structure is simple, facilitating manufacturing and production, and reducing the manufacturing difficulty.

[0071] Specifically, one vertical connecting section 132 and one vertical bracket section 212 each have a rotating through hole 53. The structure is simple, facilitating manufacturing and production, and reducing the manufacturing difficulty.

[0072] In a specific embodiment, an assembly hanging block 24 is fixed to the top of the upper bracket 21 for hanging in the upper track 2. In actual application, the upper track 2 will specifically include an upper track section one 201 and an upper track section two 202 arranged vertically. The width of the upper track section one 201 is greater than the width of the upper track section two 202, and the width of the assembly hanging block 24 is greater than the width of the upper track section two 202. The purpose of such an arrangement is that since the upper pulley assembly will be specifically assembled in the upper track 2 during actual assembly, in order to prevent the upper pulley assembly from falling off the upper track 2, the assembly hanging block 24 is fixed to the upper bracket 21. The assembly hanging block 24 will be hung in the upper track section one 201 of the upper track 2, and the upper pulley assembly can be stably hung in the upper track 2 by using the assembly hanging block 24 to prevent the upper pulley assembly from falling off.

[0073] It should be noted that when the upper bracket 21 in the upper pulley assembly is not assembled with the upper connecting member 13, the upper pulley assembly will hang in the upper track 2 until the upper bracket 21 and the upper connecting member 13 are assembled and fixed through the rotating shaft 4 and the fastener; at this time, the assembly hanging block 24 will be pushed up and will not contact the upper rail section 201 of the upper track 2, so as to improve the smoothness during pushing and pulling and reduce the sliding friction force.

[0074] It should also be noted that the upper pulley 22 will be specifically assembled to roll within the upper rail section 2020 of the upper track 2.

[0075] In a specific embodiment, the lower pulley assembly is specifically assembled in the lower frame 12. The lower pulley assembly includes a lower bracket 31 fixed in the lower frame 12 and a lower pulley 32 rotatably arranged with the lower bracket 31. The lower track 3 is provided with an inclined lower rail section 33, and the lower pulley 32 is slidably arranged on the lower rail section 33. With such a setting, it can be seen that the assembly position of the lower pulley assembly is different from that of the upper pulley assembly. The upper pulley assembly is specifically assembled in the upper track 2, while the lower pulley assembly is specifically assembled in the lower frame 12. The purpose of such a setting is that by assembling the lower pulley assembly in the lower frame 12, the supporting effect of the lower frame 12 can be well utilized for load-bearing, improving the strength and safety of the sliding structure, and at the same time facilitating the assembly of this sliding door structure.

[0076] In a specific embodiment, multiple door body structures can be provided. There are two spaced upper rail grooves 23 in the upper track 2, and there are two spaced lower rail sections 33 in the lower track 3. For one of the adjacent two door body structures, the upper pulley assembly is slidably arranged in one of the upper rail grooves 23 of the upper track 2 and the lower pulley assembly is slidably arranged in one of the lower rail sections 33 of the lower track 3. For the other, the upper pulley assembly is slidably arranged in the other upper rail groove 23 of the upper track 2 and the lower pulley assembly is slidably arranged in the other lower rail section 33 of the lower track 3. With such a setting, a structure in which two adjacent door body structures are stacked and staggered can be formed to realize the opening and closing of multiple door body structures.

[0077] Embodiment Two - Cabinet

[0078] The embodiment of the present invention also discloses a cabinet, including the above-mentioned sliding door structure, and specifically further includes a main body 7, and the main body 7 has an assembly port 71 for assembling the sliding door structure. It should be noted that the mentioned cabinet can specifically be cabinets such as refrigerators, freezers or display cabinets.

[0079] In a specific embodiment, a card slot 34 is recessed at the bottom of the lower rail 3, and the card slot 34 extends to both sides of the lower rail 3 along the pushing and pulling direction at the bottom of the lower rail 3; a limiting block 8 is clamped in the card slot 34, and the limiting block 8 is fixed at the bottom of the assembly port 71 of the main body 7. In actual assembly, since it is necessary to calculate in advance the height in the vertical direction and the length in the horizontal direction of the two points at the top and bottom of the sliding door structure of the present application, and reasonably assemble the specific positions of the upper rail 2 and the lower rail 3, the assembly structure of the lower rail 3 specifically adopts the limiting block 8 and the card slot 34 to achieve. That is, after determining the assembly position of the lower rail 3, the limiting block 8 can be first fixed at the bottom of the assembly port 71 of the main body 7, and then the card slot 34 of the lower rail 3 is assembled to the position of the limiting block 8, and the limiting and fixing of the lower rail 3 is realized by the clamping action of the limiting block 8 and the card slot 34.

[0080] It should be noted that the above-mentioned limiting and fixing of the lower rail 3 can essentially specifically use the limiting block 8 to adjust the specific assembly position of the lower rail 3, that is, the position of the lower rail 3 along the left and right directions at the main body 7 can be specifically adjusted. The left and right directions of the main body 7 can be referred to Figure 9 .

[0081] Specifically, for the fixing structure between the limiting block 8 and the assembly port 71 of the main body 7, it can be specifically, for example, that the limiting block 8 and the assembly port 71 of the main body 7 can be specifically connected by screws or bolts, or can also be bonded by adhesives, etc.

[0082] In a specific embodiment, an assembly groove 72 is recessed at the top of the assembly port 71 of the main body 7, and the upper rail 2 is connected with an upper bracket 9, and the upper bracket 9 is fixed in the assembly groove 72. The assembly structure of the upper rail 2 specifically adopts the upper bracket 9 and the assembly groove 72 to achieve. That is, after determining the assembly position of the upper rail 2, the upper bracket 9 can be first assembled on the upper rail 2, and then the upper bracket 9 is fixed in the assembly groove 72 of the main body 7. The purpose of such a setting is, firstly, the upper bracket 9 can be specifically hidden in the assembly groove 72, and the overall structure will be more compact, further reducing the occupied space; secondly, the force-bearing and pressure-bearing can be transferred to the upper bracket 9 and the assembly groove 72 of the main body 7, reasonably sharing the force and extending the service life; thirdly, since the assembly groove 72 itself has a certain depth, the upper bracket 9 can be fixed at different depth positions of the assembly groove 72. Therefore, in the actual assembly process, the height of the upper bracket 9 can be adjusted to adjust the height difference to overcome the tolerance, that is, to adjust the height position of the upper bracket 9 along the up and down directions at the main body 7. The up and down directions of the main body 7 can be referred to Figure 9 .

[0083] It should be noted that since the upper track 2 is specifically assembled on the upper frame 9, adjusting the vertical height position of the upper frame 9 is equivalent to adjusting the vertical height of the upper track 2. After determining the specific assembly positions of the upper track 2 and the lower track 3 in this sliding door structure, the inclination angle of this sliding door structure can be determined. However, in actual production and manufacturing, there may be certain tolerances for the same type of cabinet body. Therefore, the lower track 3 can be adjusted left and right specifically by using the limit block 8, and the upper track 2 can be adjusted up and down by using the height of the upper frame 9 in the assembly groove 72, which can not only well overcome the tolerances, but also better adapt and assemble with the cabinet body after adjustment.

[0084] Another point that needs to be explained is that since the sliding door structure of this application can adapt to scenarios with multiple different inclination angles, cabinets with different inclination angle requirements can be produced and manufactured in actuality. Therefore, the lower track 3 can also be specifically adjusted left and right by using the limit block 8, and the upper track 2 can be adjusted up and down by using the height of the upper frame 9 in the assembly groove 72. After adjustment, it can well adapt and assemble with cabinets with different inclination angle requirements.

[0085] In a specific embodiment, the bottom of the upper track 2 does not protrude from the bottom of the assembly groove 72. With this setting, the upper frame 9 and the upper track 2 can be hidden in the assembly groove 72 at the same time, and the overall structure is more compact, further reducing the occupied space.

[0086] It also should be noted that, overall, the use of fastening workpieces such as screws or bolts can be effectively reduced. The reason is that when the upper frame 9 is assembled into the assembly groove 72, the inclined overall structure itself will form a good self-locking structure. At the same time, since the main load of the overall sliding door structure is at the lower pulley assembly, the manufacturing cost can be reduced while ensuring normal pushing and pulling.

[0087] Specifically, for the fixing structure between the upper frame 9 and the assembly groove 72 of the main body 7, it can be specifically, for example, the upper frame 9 and the assembly groove 72 of the main body 7 can be specifically connected by screws or bolts, or can also be bonded by adhesives, etc.

[0088] Specifically, the upper frame 9 and the upper track 2 can be specifically fixed by screws or bolts.

[0089] Embodiment Three - Assembly Method

[0090] The embodiment of the present invention also discloses an assembly method, which can be specifically applied to the above-mentioned sliding door structure. This assembly method specifically includes the following steps:

[0091] Based on the overall height of the door body structure, determine the assembly positions of the upper track 2 and the lower track 3, and perform the assembly;

[0092] Assemble the upper pulley 22 assembly into the upper track 2;

[0093] Assemble the lower pulley 32 assembly into the lower frame 12 of the door structure;

[0094] Place the door structure obliquely. First, assemble the lower pulley 32 of the door leaf 1 structure at the lower track 3. After adjusting to the preset inclination angle, assemble and fix the upper bracket 21 of the upper pulley 22 assembly and the upper connecting member 13 of the upper frame 11 through the rotating shaft 4 and fasteners.

[0095] It should be noted that when assembling this sliding door structure, since the overall height of the sliding door in practice is relatively determined, after determining the specific assembly positions of the upper track 2 and the lower track 3 in this sliding door structure, the inclination angle of this sliding door structure can be determined. Therefore, in actual assembly, the assembly positions of the upper track 2 and the lower track 3 can be determined according to the overall height of the sliding door, so that this sliding door structure can finally be placed obliquely.

[0096] Therefore, for different inclined application scenarios, different assembly positions of the upper track 2 and the lower track 3 can be determined, so that the finally inclined placement angles of this sliding door structure are also different. At the same time, for the convenience of assembly, a specifically detachable rotating shaft 4 structure and a matching structure of detachable fixing bolts 61 and fixing nuts 62 are adopted, which will make the connection between the upper connecting member 13 and the upper bracket 21 specifically detachable. When assembly is required, other workpieces can be assembled to the appropriate positions first. For example, calculate in advance the overall height of the sliding door structure of this application, determine the specific assembly positions of the upper track 2 and the lower track 3 based on this overall height, specifically assemble the upper track 2 and the lower track 3 to the appropriate positions on the cabinet body or the wall, specifically assemble the upper pulley assembly into the upper track 2, and assemble the lower pulley assembly into the lower frame 12. At this time, the door leaf 1 can be placed obliquely. First, specifically install the lower pulley 32 at the lower track 3. Taking the contact area between the lower pulley 32 and the lower track 3 as the rotation point, rotate the door leaf 1 upward until the rotation through holes 53 of the upper connecting member 13 and the upper bracket 21 of the door leaf 1 are aligned, assemble the rotating shaft 4 into the two rotation through holes 53, and finally tighten the fixing nut 62 on the fixing bolt 61 to complete the assembly.

[0097] The embodiment of the present invention also discloses an assembly method, which can be specifically applied to the above-mentioned sliding door structure. This assembly method specifically includes the following steps:

[0098] Determine the assembly positions of the upper track 2 and the lower track 3 based on the overall height of the door structure;

[0099] Assemble the upper track 2 and the upper frame 9 into the assembly groove 72 of the cabinet body;

[0100] Place the lower track 3 at the bottom of the assembly opening 71 of the cabinet body through the limit block 8;

[0101] Assemble the upper pulley 22 assembly into the upper track 2;

[0102] Assemble the lower pulley 32 assembly into the lower frame 12 of the door structure;

[0103] Place the door structure obliquely. First, assemble the lower pulley 32 of the door leaf 1 structure at the lower track 3. After adjusting to the preset inclination angle, assemble and fix the upper bracket 21 of the upper pulley 22 assembly and the upper connecting piece 13 of the upper frame 11 through the rotating shaft 4 and fasteners.

[0104] It should be noted that when assembling this sliding door structure, since the overall height of the sliding door in reality is relatively determined, only after determining the specific assembly positions of the upper track 2 and the lower track 3 in this sliding door structure can the inclination angle of this sliding door structure be determined. Therefore, in actual assembly, the assembly positions of the upper track 2 and the lower track 3 can be determined according to the overall height of the sliding door so that this sliding door structure can finally be placed obliquely.

[0105] For the assembly of the upper track 2, the upper track 2 can be specifically assembled on the upper frame 9. Since the assembly groove 72 itself has a certain depth and the upper frame 9 can be fixed at different depth positions of the assembly groove 72, adjusting the up and down height position of the upper frame 9 is to adjust the up and down height of the upper track 2. The up and down position of the upper track 2 can be adjusted up and down by using the height of the upper frame 9 in the assembly groove 72. For the assembly of the lower track 3, the limit block 8 can be specifically used for assembly, which can be specifically adjusted left and right for the lower track 3 by using the limit block 8. Therefore, through the upper frame 9 and the limit block 8, the upper track 2 can have the function of adjusting the up and down height, and the lower track 3 can have the function of adjusting the left and right position, which can be adapted to different inclined application scenarios. Therefore, for different inclined application scenarios, the different assembly positions of the upper track 2 and the lower track 3 can be adjusted through the upper frame 9 and the limit block 8.

[0106] Meanwhile, for the convenience of assembly, a detachable rotating shaft 4 structure and a matching structure of detachable fixing bolts 61 and fixing nuts 62 are specifically adopted, which makes the connection between the upper connecting member 13 and the upper bracket 21 specifically detachable. When assembly is required, other workpieces can be assembled to appropriate positions first. For example, calculate in advance the overall height of the sliding door structure of the present application, and determine the specific assembly positions of the upper track 2 and the lower track 3 based on this overall height, and specifically assemble the upper track 2 and the lower track 3 to appropriate positions on the cabinet body or the wall, specifically assemble the upper pulley assembly into the upper track 2, and assemble the lower pulley assembly into the lower frame 12. At this time, the door leaf 1 can be placed obliquely. First, specifically install the lower pulley 32 at the lower track 3. Taking the contact area between the lower pulley 32 and the lower track 3 as the rotation point, rotate the door leaf 1 upward until the rotation through holes 53 of the upper connecting member 13 and the upper bracket 21 of the door leaf 1 are aligned with each other, assemble the rotating shaft 4 into the two rotation through holes 53, and finally tighten the fixing nut 62 on the fixing bolt 61 to complete the assembly.

[0107] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
