Description

Technical Field

[0001] This utility model relates to the field of tea conveying, specifically a tea conveying mechanism. Background Technology

[0002] my country is the origin of tea, and its annual tea production is enormous. Traditional manual harvesting can no longer meet the demand, leading to the increasing use of mechanized tea-picking equipment. While the harvesting speed is getting faster, existing tea-picking machines do not prioritize the protection of tea leaves during the picking process. Currently, most tea-picking machines have a blower in front of the cutting shears to blow the cut tea leaves into a collection bin, or a conveyor belt below the shears where the cut tea leaves fall and are transported. Alternatively, the machine can be moved quickly to allow the cut tea leaves to roll naturally into the collection bin.

[0003] For example, the tea-picking machine disclosed in CN104335765A includes a frame with a handle, a tea-absorbing pipe with multiple air inlets horizontally placed on the frame, the tea-absorbing pipe being connected to a tea storage bag via a suction fan; a tea-picking pipe fitted with driven gears is inserted into each air inlet, a synchronous belt is wrapped around these driven gears, and a drive gear connected to a diesel engine via a flexible shaft is provided on the frame to drive the synchronous belt to rotate; a bushing supporting the tea-picking pipe is provided below the air inlet of the tea-absorbing pipe on the frame.

[0004] For example, the tea-picking machine disclosed in CN109661901A includes a housing, a feeder, a tea-picking motor, and a cutting arm. The housing has a collection chamber, with a picking opening and a discharge opening on opposite sides of the collection chamber. The feeder is rotatably mounted within the collection chamber and connected to the tea-picking motor. The cutting arm is elastically oscillating within the picking opening, oscillating upon contact with the feeder. The machine also includes an air supply system comprising a fan and an air duct assembly. The fan has an inlet and an outlet, the outlet communicating internally with the air duct assembly. The air duct assembly has a blowing nozzle located within the collection chamber and pointing inwards towards the picking opening. The fan and tea-picking motor are located at opposite ends of the housing. This tea-picking machine has a built-in air supply system that blows the tea leaves picked into the collection chamber out of the discharge opening.

[0005] The aforementioned technical solutions all result in tea leaves being impacted, leading to damage and reduced quality. Furthermore, these solutions do not effectively manage the unified feeding, cutting, and transportation of tea leaves requiring trimming. Therefore, a tea conveying structure is needed to prevent damage during harvesting and to better centrally feed, cut, and transport tea leaves requiring trimming, thereby solving the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a tea conveying mechanism that can avoid damage to tea leaves during tea picking and transportation, and can complete the feeding, picking and transportation of tea leaves in a more centralized manner, so as to improve the efficiency of tea picking and transportation, and solve the existing technical defects and unmet technical requirements.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a tea conveying mechanism, comprising at least one feeding unit, wherein the feeding unit comprises a first conveying component and a second conveying component, wherein a conveying channel and a feed inlet are formed between the first conveying component and the second conveying component, the feed inlet gradually narrows from the front end of the feeding unit to the conveying channel, and the feed inlet is formed by at least two inclined surfaces, wherein the tea branches and leaves are gathered from the feed inlet into the conveying channel, and are transported to a preset position by being clamped by the first conveying component and the second conveying component.

[0008] In this application, it is necessary to further explain that the feed inlet is located at the front end of the conveying channel, while the discharge outlet is located at the rear end of the conveying channel, and the three are connected in sequence. From the two inclined surfaces mentioned above, it can be reasonably understood that the discharge outlet is located between the first conveying component and the second conveying component, and the two inclined surfaces are respectively located on the first conveying component and the second conveying component. In addition, the reference standard for front and rear in this application is: the part that comes into contact with the tea leaves first is the front, and the part that comes into contact with the tea leaves last is the rear.

[0009] Preferably, the adjacent feeding units are symmetrically arranged, and the conveying channels in each feeding unit are parallel to each other. The front ends of the two adjacent first conveying components and the two adjacent second conveying components are provided with leaf-picking mechanisms. The leaf-picking mechanisms can swing to comb the tea leaves to both sides, assisting the tea leaves to enter the conveying channels.

[0010] In this application, the above content can be understood as follows: the leaf-picking mechanism is rotatably connected to the base, and one end of it extends forward at an angle to the front of each pair of adjacent and identical conveying components.

[0011] Preferably, both the first conveying assembly and the second conveying assembly include a conveyor belt and a plurality of pulleys. The conveyor belt is sleeved around the pulleys to form a loop. The outer side wall of the pulleys is provided with a plurality of protrusions to prevent the conveyor belt from falling off the pulleys.

[0012] Preferably, it also includes a base for mounting each pulley, the pulley being rotatably connected to the base.

[0013] Preferably, the first conveying assembly includes: a first pulley, a second pulley, a third pulley, and a first conveyor belt. The first pulley is located at the front end of the base, the third pulley is located at the rear end of the base, the second pulley is located between the first pulley and the third pulley, and the first conveyor belt is sleeved on the first pulley, the second pulley, and the third pulley.

[0014] The second conveying assembly includes a fourth pulley, a fifth pulley, a sixth pulley, and a second conveyor belt. The fourth pulley is located at the front end of the base, the sixth pulley is located at the rear end of the base, the fifth pulley is located between the fourth and sixth pulleys, and the second conveyor belt is sleeved over the fourth, fifth, and sixth pulleys.

[0015] The conveyor belt between the first and second pulleys forms an inclined surface around the feed inlet, and the conveyor belt between the fourth and fifth pulleys forms another inclined surface around the feed inlet. A conveying channel is formed between the first conveyor belt between the second and third pulleys and the second conveyor belt between the fifth and sixth pulleys.

[0016] Preferably, the front end of the first conveying component is located on the side rear of the front end of the second conveying component to form a discharge port that is wider at the front and narrower at the back.

[0017] In this application, regarding the above content, firstly, the horizontal position refers to the position in the horizontal direction. The reference standard for the horizontal direction in this application is the left-right direction. The above content can be understood as the projection of the second pulley on the second conveyor belt being located between the projections of the fifth pulley and the sixth pulley on the second conveyor belt, and the projection of the first pulley on the second pulley being located between the projections of the fourth pulley and the fifth pulley on the second pulley. This can be understood as the front ends of the first conveying component and the second conveying component being staggered.

[0018] Preferably, the third pulley is located at a forward position on the side of the sixth pulley, forming a discharge port connected to the rear end of the conveying channel;

[0019] Alternatively, the third pulley may be located at a rearward position on the side of the sixth pulley, forming a discharge port connected to the rear end of the conveying channel.

[0020] In this application, the above content can be understood as follows: the rear ends of the first conveying component and the second conveying component are set at different lengths. The staggered distribution of the first conveying component and the second conveying component at the discharge port does not necessarily correspond to the staggered distribution of the first conveying component and the second conveying component at the feed port. That is, it can be understood that if the front end of the first conveying component at the feed port is to the side and in front of the front end of the second conveying component, that is, the first feed component is further forward at the feed port, then at the discharge port, either the rear end of the first conveying component is behind or the second conveying component is behind. The situation at the discharge port is the opposite. Of course, this also includes the case where the rear ends of the first conveying component and the second conveying component are flush.

[0021] Preferably, the width of the conveying channel is no more than 5 mm.

[0022] Preferably, the included angle between the two inclined surfaces on the feed inlet is in the range of 2° to 179°.

[0023] In this application, the above content can be understood as the bending angle formed by the second belt between the fourth and fifth pulleys and the second conveyor belt between the fifth and sixth pulleys being 91° to 179°. Similarly, the bending angle formed by the second belt between the first and second pulleys and the second conveyor belt between the second and third pulleys is also 90° to 150°. Therefore, the angle between the inclined surface of the first conveyor belt between the first and second pulleys and the inclined surface of the second conveyor belt between the fourth and fifth pulleys is 2° to 179°. However, it needs to be further explained that although the angle range of the first conveying component and the second conveying component in the above content is 2° to 179°, although the angle range is the same, the angles are not necessarily the same. That is, they can be the same or different, as long as the angle range of the discharge port is within 2° to 179°.

[0024] Preferably, the second and fifth pulleys can move back and forth to adjust the opening angle of the feed inlet and the length of the conveying channel;

[0025] The second and fifth pulleys can move left and right to adjust the opening angle of the feed inlet and the width of the conveying channel.

[0026] Preferably, the front ends of the two adjacent first conveying components and the two adjacent second conveying components are provided with leaf-picking mechanisms. The leaf-picking mechanisms can swing to comb the tea leaves to both sides, assisting the tea leaves to enter the conveying channel.

[0027] Specifically, the leaf-picking mechanism is provided with a rotating end and a free end. The rotating end is rotatably connected to the top of the base 8 located above the pulley, and the free end extends out of the base in a direction away from the base.

[0028] Both the second and fifth pulleys are equipped with eccentric wheel portions (cams);

[0029] The leaf-dispensing mechanism is equipped with a driven member located between the free end and the rotating end of the mechanism. The driven member above the first conveying assembly simultaneously abuts against the eccentric wheel portions of two symmetrically arranged second pulleys on its base, and the driven member above the second conveying assembly simultaneously abuts against the eccentric wheel portions of two symmetrically arranged fifth pulleys on its base. The two second pulleys on the same base rotate synchronously, and the two fifth pulleys on the same base also rotate synchronously, allowing the free end to swing. It should be emphasized that the symmetrical arrangement of the eccentric portions on the second and fifth pulleys refers to positional symmetry and identical shapes, but the rotational... The states are the same (the eccentric wheel parts with the same radius all face the same direction when rotating). That is, if the eccentric wheel part on one of the second pulleys (or the eccentric wheel part on the fifth pulley) abuts against the driven part at the position with the smallest radius, then the eccentric wheel part on the other second pulley (or the eccentric wheel part on the fifth pulley) abuts against the driven part at the position with the largest radius, and so on. Only in this way can the driven part complete the displacement of left and right movement, thereby realizing the swing of the oscillating blade, instead of abutting against the driven part at the same radius position at the same time. This obviously does not meet the assembly requirements. The eccentric wheel part and the corresponding pulley rotate coaxially, which can be understood as the eccentric wheel part rotating with the pulley.

[0030] This can be understood as two symmetrically arranged first conveying components or two symmetrically arranged second conveying components being installed on each set of bases.

[0031] Alternatively, the second pulley may have an eccentric wheel portion, with the driven member abutting against the eccentric wheel portion;

[0032] An elastic element is provided on the base. One end of the elastic element is connected to the base, and the other end abuts against the side of the driven element away from the position where the driven element abuts against the eccentric wheel.

[0033] In this application, the above content can be understood as follows: from an overall perspective, the eccentric wheel part that abuts against the driven part and the elastic element are located on both sides of the leaf-dispensing mechanism.

[0034] Compared with the prior art, the beneficial effects of this utility model are:

[0035] 1. This application uses a pulley to drive the belt to rotate, forming a conveying assembly. Two belts are close to each other to form a conveying channel for clamping and conveying tea leaves. Tea leaves entering from the feed inlet are clamped by the close belts and transported to a designated collection location. The conveying channel between the belts can be adjusted to accommodate different types of tea leaves. While ensuring stable clamping of tea leaves, it can avoid squeezing and damaging the tea leaves. Moreover, the belts move at a consistent speed, avoiding friction damage to the tea leaves. At the same time, multiple feeding units are set up to feed together, which can improve the speed and efficiency of clamping and conveying tea leaves. The staggered arrangement of the first and second conveying assemblies also saves space, and the formed feed inlet is also convenient for feeding.

[0036] 2. By setting protrusions, this application makes the connection between the conveyor belt and the pulley more stable when the conveyor belt is sleeved on the pulley, and prevents the conveyor belt from falling off the pulley during operation.

[0037] 3. The top of each of the two adjacent first conveyor belt assemblies and the two adjacent second conveyor belt assemblies in this application is provided with a leaf-picking mechanism; the leaf-picking mechanism is used to assist in sorting the tea leaves. When the tea leaves are very dense and complex, the leaf-picking mechanism can help the tea leaves enter the conveying channel better. Attached Figure Description

Detailed Implementation

[0046] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0048] Please see Figure 1-7 Embodiments of this utility model:

[0049] Example 1:

[0050] like Figure 1-2 As shown: A tea conveying mechanism includes at least one feeding unit, which includes a first conveying component 1 and a second conveying component 2. A conveying channel 3 and a feed inlet 4 are formed between the first conveying component 1 and the second conveying component 2. The feed inlet 4 gradually narrows from the front end of the feeding unit to the conveying channel 3, and the feed inlet 4 is formed by at least two inclined surfaces. The tea branches and leaves are gathered into the conveying channel 3 from the feed inlet 4 and transported to a preset position by the first conveying component 1 and the second conveying component 2.

[0051] Specifically, the adjacent feeding units are symmetrically arranged, and the conveying channels 3 in each feeding unit are parallel to each other. In this embodiment, the feed inlet 4 is composed of two inclined surfaces and a plane 20, namely, the first inclined surface 18, the second inclined surface 19 and the plane 20 are arranged. The first inclined surface 18 is disposed on the first conveying component, and the second inclined surface 19 and the plane 20 are located on the second conveying component 2.

[0052] In this embodiment, by setting a first conveying component 1 and a second conveying component 2, a conveying channel for clamping and conveying tea leaves is formed. Tea leaves entering from the feed inlet 4 are clamped by belts that are close to each other and transported to a designated location for collection. The conveying channel between the belts can be adjusted to accommodate different types of tea leaves. While ensuring stable clamping of tea leaves, it can avoid squeezing and damaging the tea leaves. Moreover, the belts move at the same speed, avoiding friction damage to the tea leaves. At the same time, multiple feeding units are set up to feed together, which can improve the speed and efficiency of clamping and conveying tea leaves. The staggered arrangement of the first conveying component and the second conveying component also helps to save space, and the feed inlet 4 formed is also convenient for feeding.

[0053] like Figure 1 As shown: The first conveying component 1 and the second conveying component 2 both include a conveyor belt and a plurality of pulleys. The conveyor belt is sleeved on the outside of the pulleys to form a loop. The outer side wall of the pulleys is provided with a plurality of protrusions 6 to prevent the conveyor belt from falling off the pulleys.

[0054] In this embodiment, the protrusion 6 can make the conveyor belt and the pulley more stable during transmission in the vertical direction, preventing the conveyor belt from falling off the pulley. In addition, in the horizontal direction, it can increase the contact force between the conveyor belt and the pulley, further increasing the stability of their transmission. Furthermore, the protrusion 6 also increases the contact area between the pulley and the conveyor belt, enhancing the contact stability between the pulley and the conveyor belt.

[0055] like Figure 3-4 As shown: It also includes a base 8, which is respectively disposed on the upper end of a plurality of pulleys, and the pulleys are rotatably connected to the base 8.

[0056] In this embodiment, it can be understood that the upper end of the pulley is set on the base 8, and each feeding unit is provided with a base 8.

[0057] like Figure 1-2 As shown: The first conveying assembly 1 includes: a first pulley 9, a second pulley 10, a third pulley 11, and a first conveyor belt 12. The first pulley 9 is located at the front end of the base 8, the third pulley 11 is located at the rear end of the base 8, the second pulley 10 is located between the first pulley 9 and the third pulley 11, and the first conveyor belt 12 is sleeved on the first pulley 9, the second pulley 10, and the third pulley 11. The distance between the third pulley 11 and the second pulley 10 is greater than the distance between the first pulley 9 and the second pulley 10. The distance from the rotation axis of the second pulley 10 and the rotation axis of the third pulley 11 to the conveying channel 3 is the same, and this distance is less than the distance from the rotation axis of the first pulley 9 to the conveying channel 3.

[0058] The second conveying assembly 2 includes a fourth pulley 13, a fifth pulley 14, a sixth pulley 15, and a second conveyor belt 16. The fourth pulley 13 is located at the front end of the base 8, the sixth pulley 15 is located at the rear end of the base 8, and the fifth pulley 14 is located between the fourth pulley 13 and the sixth pulley 15. The second conveyor belt 16 is sleeved on the fourth pulley 13, the fifth pulley 14, and the sixth pulley 15. The distance between the sixth pulley 15 and the fifth pulley 14 is greater than the distance between the fourth pulley 13 and the fifth pulley 14. The distance from the rotation axis of the fifth pulley 14 and the rotation axis of the sixth pulley 15 to the conveying channel 3 is the same, and this distance is less than the distance from the rotation axis of the fourth pulley 13 to the conveying channel 3.

[0059] The conveyor belt between the first pulley 9 and the second pulley 10 forms an inclined surface surrounding the feed inlet 4, and the conveyor belt between the fourth pulley 13 and the fifth pulley 14 forms another inclined surface surrounding the feed inlet 4. The first conveyor belt 12 between the second pulley 10 and the third pulley 11 and the second conveyor belt 16 between the fifth pulley 14 and the sixth pulley 15 form a conveying channel 3.

[0060] like Figure 1-2 As shown: the front end of the first conveying component 1 is located on the side and rear of the front end of the second conveying component 2; the horizontal position of the rotation center of the second pulley 10 is located between the rotation center of the fifth pulley 14 and the rotation center of the sixth pulley 15; and the horizontal position of the rotation center of the first pulley 9 is located between the rotation center of the fourth pulley 13 and the rotation center of the fifth pulley 14, so as to form a feed inlet 4 that is wider at the front and narrower at the back.

[0061] In this embodiment, as can be seen from the above, the three surfaces of the discharge port 17 are: the first inclined surface 18 is a section of the first conveyor belt 12 inclined between the first pulley 9 and the second pulley 10; the second inclined surface 19 is a section of the second conveyor belt 16 inclined between the fourth pulley 13 and the fifth pulley 14; and the plane 20 is the second pulley 10 between the second pulley 10 and the fifth pulley 14.

[0062] like Figure 2 As shown: The third pulley 11 is located at a rearward position on the side of the sixth pulley 15, forming a discharge port 17 connected to the rear end of the conveying channel 3.

[0063] In this embodiment, the specifications of the first conveying component 1 and the second conveying component 2 are set to be the same, except that the position of the first conveying component is moved backward, so that the front end of the first conveying component 1 at the discharge port 17 is at the rear, and the rear end of the first conveying component 1 at the discharge port 17 is also relatively at the rear.

[0064] The width of the conveying channel 3 is 5mm.

[0065] The included angle between the two inclined surfaces on the feed inlet 4 ranges from 2° to 179°.

[0066] The second pulley 10 and the fifth pulley 14 can move back and forth to adjust the opening angle of the feed inlet 4 and the length of the conveying channel 3.

[0067] The second pulley 10 and the fifth pulley 14 can move left and right to adjust the opening angle of the feed inlet 4 and the width of the conveying channel 3.

[0068] like Figure 3-6 As shown: The front ends of the two adjacent first conveying components 1 and the two adjacent second conveying components 2 are provided with leaf-picking mechanisms 5. The leaf-picking mechanisms 5 can swing to comb the tea leaves to both sides and help the tea leaves enter the conveying channel 3.

[0069] Specifically, the leaf-picking mechanism 5 is provided with a rotating end 22 and a free end 21. The rotating end 22 is rotatably connected to the top of the base 8 located above the pulley, and the free end 21 extends out of the base 8 in a direction away from the base 8.

[0070] Both the second pulley 10 and the fifth pulley 14 are provided with an eccentric wheel portion (cam);

[0071] The leaf-dispensing mechanism 5 is provided with a follower 23, which is located between the free end 21 and the rotating end 22 of the leaf-dispensing mechanism 5. The follower 23 above the first conveying component 1 abuts against the eccentric wheel portions of the two symmetrically arranged second pulleys 10 on the base 8. The follower 23 above the second conveying component 2 abuts against the eccentric wheel portions of the two symmetrically arranged fifth pulleys 14 on the base 8. The two second pulleys 10 on the same base 8 rotate synchronously, and the two fifth pulleys 14 on the same base 8 also rotate synchronously, so that the free end 21 can swing.

[0072] A comb leaf portion 24 is provided on the free end 21. One end of the comb leaf portion 24 is connected to the free end 21, and the other end is inclined downward away from the base 8. The width of the comb leaf portion 24 gradually decreases along the inclined direction. The width of the comb leaf portion gradually decreases along the inclined direction. In this sentence, the inclined direction consists of two directions, namely the vertical direction and the horizontal direction (the horizontal direction from the front end to the rear end). Therefore, the above-mentioned width gradually changes along the inclined direction means that the width changes in both the horizontal and vertical directions. That is, it can be understood as the width gradually decreases from top to bottom and from back to front.

[0073] This can be understood as two symmetrically arranged first conveying components 1 or two symmetrically arranged second conveying components 2 being installed on each set of bases 8.

[0074] In this embodiment, taking the first conveying component 1 as an example, the follower 23 abuts against the middle of the eccentric wheel portion on the two second pulleys on the same base 8. Because the two first conveying components 1 are symmetrically arranged, this symmetry is both positional and overall shape symmetry. Specifically, the positions of the two eccentric wheel portions are symmetrical, but the eccentric wheel portions deflect in the same direction. Therefore, when the two eccentric wheel portions rotate synchronously, taking the extreme position as an example, when one side of the follower 23 abuts against the most protruding position (largest radius) of the eccentric wheel portion, the other side abuts against the least protruding position (smallest radius) of the other eccentric wheel portion, and vice versa. Therefore, under the relative abutment of the rotational cooperation of the two, the follower 23 can complete the reciprocating offset, i.e., swing. As for the two first conveyor belts 12 on the adjacent base 8 that can form the conveying channel 3, under the abutment of the synchronously rotating eccentric wheel portions, the two first conveyor belts 12 move in the same direction (left and right), so that the width of the conveying channel 3 remains unchanged, avoiding the influence of the eccentric wheel portion arrangement on the tea transportation.

[0075] Furthermore, in this embodiment, it is necessary to further explain that, as mentioned above, the driven member 23 needs to abut against the eccentric wheel portion of the second pulley in each of the two symmetrically arranged first conveying components 1, and these two second pulleys also need to abut against their respective corresponding first conveyor belts 12. Therefore, in order to ensure that the eccentric wheel portion can complete the above connection, in this embodiment, the abutment position of the eccentric wheel portion and the driven member 23 is set at a different height from the abutment position of the second pulley and the first conveyor belt 12. That is, in this embodiment, the abutment position of the eccentric wheel portion and the driven member 23 is set above the abutment position of the second pulley and the first conveyor belt 12.

[0076] Based on the arrangement of the leaf-picking mechanism 5 in this embodiment, the protrusion 6 can further ensure the realization of the above content.

[0077] In this embodiment, the leaf-picking mechanism 5 swings to comb and move the tea leaves to both sides, which helps the tea leaves enter the conveying channel 3 more effectively along the feeding port during tea picking, thus improving the efficiency of tea picking and sorting. Furthermore, with the assistance of the leaf-picking mechanism 5, when the equipment moves forward during use, it prevents the tea leaves from being pushed over or bent, which would make it difficult for the tea leaves to be held by the conveying components, thereby affecting the harvesting and cleaning rate.

[0078] Example 2:

[0079] The difference between this embodiment and Embodiment 1 is that the oscillation of the leaf-picking mechanism is achieved.

[0080] like Figure 7 As shown: In this embodiment, the second pulley is provided with an eccentric wheel portion, and the driven member abuts against the eccentric wheel portion;

[0081] An elastic element 25 is provided on the base. One end of the elastic element 25 is connected to the base, and the other end abuts against the side of the driven member away from the position where the driven member abuts against the eccentric wheel.

[0082] In this application, the above content can be understood as follows: from an overall perspective, the eccentric wheel part that abuts against the driven part and the elastic element 25 are located on both sides of the leaf-pulling mechanism.

[0083] When the eccentric wheel rotates with the second pulley 10, it abuts against the driven member 23 with different radii. When it abuts against the driven member 23 with a larger radius, the front end (free end) of the leaf-pulling mechanism can move away from the rotation center of the second pulley 10 where the eccentric wheel is located, thereby squeezing the elastic member 25. When it abuts against the driven member 23 with a smaller radius, the driven member moves towards the rotation center of the second pulley 10 under the elasticity of the elastic member 25, until it resets and completes the swing.

[0084] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0085] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
