Candle cotton swab feeding mechanism with anti-blocking structure

Abstract

The utility model discloses a candle cotton swab feeding mechanism with a material blocking prevention structure, and relates to the technical field of candle cotton swab forming. An arc-shaped material blocking prevention element is arranged above a feeding gear, and the material blocking prevention element and the feeding gear are coaxially arranged; the distance between the bottom face of the arc-shaped plate and the root circle of the feeding gear is larger than the diameter of the bamboo core and smaller than two times of the diameter of the bamboo core, so that after the bamboo core is rolled up by the feeding gear and enters the position between the anti-blocking element and the feeding gear, the redundant bamboo core can be extruded out of the feeding gear by the anti-blocking element, and therefore the feeding efficiency of the bamboo core is improved. Therefore, only a single bamboo core can be contained between every two teeth of the feeding gear, and the situation that the bamboo cores are stuck during transferring is prevented.

Description

Technical Field

[0001] This utility model belongs to the field of candle swab forming technology, specifically relating to a candle swab feeding mechanism with an anti-jamming structure. Background Technology

[0002] The applicant filed a utility model patent application on February 6, 2023, with patent number ZL202320179440.2, which discloses a candle cotton swab. This utility model candle cotton swab uses wax liquid to replace the paste layer. The wax liquid is solid at room temperature, which makes it easier to cool and set, and is more suitable for automated production.

[0003] In the process of forming candle cotton swabs, the bamboo cores in the hopper need to be transferred to the feeding mechanism via gears. However, the existing feeding gears are prone to jamming multiple bamboo cores at the same time within the distance between the root circle and the tip circle of the gears, which makes it easy for the feeding gears to jam during the transfer process. Utility Model Content

[0004] In order to solve the problem that the existing bamboo core is prone to material accumulation and jamming during the feeding gear transmission process, the purpose of this utility model is to provide a candle cotton swab feeding mechanism with an anti-jamming structure.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A candle swab feeding mechanism with an anti-jamming structure is disclosed. The automated candle swab forming device includes a feeding mechanism, a core-filling mechanism, a waxing mechanism, and a cooling mechanism. The feeding mechanism includes a feeding gear, a transport gear, and a transmission chain. The transport gear drives the transmission chain to rotate. The feeding gear transfers the bamboo core to the transmission chain, allowing the bamboo core to pass through the core-filling mechanism, the waxing mechanism, and the cooling mechanism. An anti-piling element is provided above the feeding gear. The anti-piling element is an arc-shaped plate coaxial with the feeding gear. The distance between the bottom surface of the arc-shaped plate and the root circle of the feeding gear is greater than the diameter of the bamboo core but less than twice the diameter of the bamboo core.

[0007] Optionally, the feeding mechanism also includes a friction drive rod, a transport gear for driving the transmission chain to rotate, and several limiting elements on the conveying surface of the transmission chain, forming a groove between two adjacent limiting elements that can only accommodate a single bamboo core. A friction drive rod is arranged parallel above the transmission surface of the transmission chain, and a flexible contact layer is provided at the bottom of the friction drive rod to contact and drive the bamboo core to rotate. Optionally, the feeding mechanism also includes a hopper and a feeding gear; the hopper contains a material pile consisting of several bamboo cores stacked horizontally; the feeding gear is located at the outlet end of the hopper, and the height of the feeding gear shaft is lower than the height of the hopper outlet, with the transport gear and the feeding gear arranged alternately.

[0008] Optionally, a wetting mechanism is provided between the feeding mechanism and the core feeding mechanism. The wetting mechanism includes a water inlet pipe and a wet wipe located above the transmission chain. The top of the wet wipe is fixed, and its bottom end contacts the end of the bamboo core away from the transmission chain, thereby wetting one end of the bamboo core. The water inlet pipe is used to replenish the moisture of the wet wipe.

[0009] Optionally, the core-adding mechanism includes a fabric breaking element and a negative pressure traction chamber. The fabric breaking element is installed directly above the negative pressure traction chamber. A first grid plate is provided at the bottom of the fabric breaking element, and a second grid plate is provided at the top of the negative pressure traction chamber. The fabric breaking element is used to break the fabric into flocculent material, and the negative pressure traction chamber is used to create negative pressure and pull the flocculent fabric through the first and second grid plates into the negative pressure traction chamber. One end of the bamboo core passes through the gap between the first and second grid plates and is wrapped with flocculent fabric.

[0010] Optionally, the waxing mechanism includes a wax tray and a pressure plate; the top surface of the wax tray is provided with a wax inlet pipe and a wax accumulation tank, the wax inlet pipe is used to input wax into the wax accumulation tank; the pressure plate is movably installed above the wax accumulation tank, the pressure plate is used to press down one end of the bamboo core, so that the flexible fabric core of the bamboo core enters the wax accumulation tank and is coated with wax.

[0011] Optionally, the wax tray is also connected to a wax discharge pipe, which is used to collect and discharge the wax flowing out of the wax tray.

[0012] Optionally, a first heating element is provided on the bottom surface of the wax tray; a second heating element is provided on the pressure plate.

[0013] Alternatively, the pressure plate may be arc-shaped, with the protruding part of the bottom surface of the pressure plate sinking into the wax accumulation groove.

[0014] Alternatively, the cooling mechanism is an air-cooled mechanism, which includes several fans arranged along the length of the feeding mechanism, and the fans are positioned directly above the outer dense layer of the bamboo core.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model provides a candle swab feeding mechanism with an anti-jamming structure. By setting an arc-shaped anti-jamming element above the feeding gear, the anti-jamming element is coaxially arranged with the feeding gear. The distance between the bottom surface of the arc-shaped plate and the root circle of the feeding gear teeth is greater than the diameter of the bamboo core but less than twice the diameter of the bamboo core. This ensures that after the bamboo core is rolled up by the feeding gear and enters between the anti-jamming element and the feeding gear, the excess bamboo core is squeezed out of the feeding gear by the anti-jamming element. Thus, only a single bamboo core can be accommodated between each two teeth of the feeding gear, thereby preventing the bamboo core from jamming during transmission. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] In this embodiment, as Figure 1 The candle swab feeding mechanism shown has an anti-jamming structure. The automated candle swab forming device includes a feeding mechanism 2, a core-adding mechanism 3, a waxing mechanism 4, and a cooling mechanism 5. The feeding mechanism 2 is used to separate the bamboo core 6 from the material pile, and to allow the bamboo core 6 to pass through the core-adding mechanism 3, the waxing mechanism 4, and the cooling mechanism 5 in sequence. The core-adding mechanism 3 is used to cover one end of the bamboo core 6 with a flexible fabric core. The waxing mechanism 4 is used to cover the flexible fabric core of the bamboo core 6 with wax to form an outer dense layer. The cooling mechanism 5 is used to rapidly cool the outer dense layer at one end of the bamboo core 6. Bamboo cores 6 are conveyed to the core-adding mechanism 3 via the feeding mechanism 2. The feeding mechanism 2 feeds bamboo cores 6 one at a time into the core-adding mechanism 3, where a flexible fabric core is covered on the outer surface of one end of the bamboo core 6. Then, the feeding mechanism 2 conveys the bamboo cores 6 with the flexible fabric core to the waxing mechanism 4, where the surface of the flexible fabric core is coated with a layer of wax liquid, which penetrates into the interior of the flexible fabric core. Next, the feeding mechanism 2 carries the bamboo cores 6 with their outer dense layer into the cooling mechanism. After passing through the cooling mechanism, the outer dense layer of the bamboo core 6 is rapidly cooled and shaped. The feeding mechanism 2 then conveys the bamboo cores 6 out of the cooling mechanism 5 and collects them in the receiving device (not shown in the figure) at the outlet of the cooling mechanism 5. Because the wax liquid has strong adhesion and a fast cooling speed, the cooling method can be air cooling, natural cooling, or temperature-controlled cooling. This invention can quickly attach a flexible fabric core and an outer dense layer to the bamboo core 6 and rapidly cool and shape it, making the entire production process of candle swabs shorter and more efficient. At the same time, this invention has a high degree of automation, reducing the amount of manual labor in the candle swab forming process and saving labor costs.

[0032] In this embodiment, as Figures 1-6 As shown, the feeding mechanism 2 includes a hopper 22, a feeding gear 23, a transport gear 24, and a transmission chain 25. The hopper 22 contains a material pile consisting of several bamboo cores 6 stacked horizontally. The feeding gear 23 is located at the outlet end of the hopper 22, and the height of the shaft of the feeding gear 23 is lower than the height of the outlet of the hopper 22. The transport gear 24 is used to drive the transmission chain 25 to rotate, and the transport gear 24 and the feeding gear 23 are arranged alternately. Several limiting elements 251 are provided on the conveying surface of the transmission chain 25, and a groove that can only accommodate a single bamboo core 6 is formed between two adjacent limiting elements 251.

[0033] Specifically, the feeding mechanism 2 also includes a mounting groove 21. The rotating shaft of the feeding gear 23 is installed across the mounting groove 21, and at least one end of the rotating shaft of the feeding gear 23 passes through the side wall of the mounting groove 21 and is connected to the drive motor, thereby driving the feeding gear 23 to rotate through the drive motor. At the same time, multiple sets of feeding gears 23 can be set according to actual conditions. Each set of feeding gears 23 includes at least two identical gears arranged coaxially. Both identical gears are located on one side of the mounting groove 21, so that the two gears of the feeding gear 23 simultaneously support the end of the bamboo core 6 that does not need to be waxed. The two force points support the bamboo core 6, which can effectively prevent the bamboo core 6 from tilting or falling during feeding.

[0034] In this embodiment, as Figures 2-4 As shown, an anti-stacking element 231 is provided above the feeding gear 23. By setting an arc-shaped anti-jamming element 231 above the feeding gear 23, the anti-jamming element 231 is coaxially arranged with the feeding gear 23, and the distance between the bottom surface of the arc plate and the root circle of the tooth of the feeding gear 23 is greater than the diameter of the bamboo core 6 and less than twice the diameter of the bamboo core 6, after the bamboo core 6 is rolled up by the feeding gear 23 and enters between the anti-jamming element 231 and the feeding gear 23, the excess bamboo core 6 will be squeezed out of the feeding gear 23 by the anti-jamming element 231. Thus, the feeding gear 23 can only accommodate a single bamboo core 6 between each two teeth, thereby preventing the bamboo core 6 from jamming during transmission.

[0035] In this embodiment, as Figure 4 As shown, the two ends of the arc-shaped plate are slightly upturned. The upturn of the two ends of the arc-shaped plate is conducive to the bamboo core 6 entering between the feeding gear 23 and the anti-jamming element 231.

[0036] In this embodiment, the anti-jamming element 231 is fixedly mounted on the positioning shaft 232, and the two ends of the positioning shaft 232 are mounted across the two side walls of the mounting groove 21. The positioning shaft 232 is also arranged parallel to the rotating shaft of the feeding gear 23.

[0037] In this embodiment, the present invention also includes a support mechanism 1 (such as...). Figures 1-7 As shown, the support mechanism 1 includes a base frame 11, a vertical support frame 12, and a top mounting frame 13 placed sequentially from bottom to top. The core-adding mechanism 3, the waxing mechanism 4, and the cooling mechanism 5 are arranged sequentially along the length of the base frame 11, and the feeding mechanism 2 is arranged across one side of the core-adding mechanism 3, the waxing mechanism 4, and the cooling mechanism 5.

[0038] In this embodiment, the cooling mechanism 5 is an air-cooling mechanism, which includes several fans arranged along the length of the feeding mechanism 2. Specifically, the fans are installed on the top mounting bracket 13 and located directly above the outer dense layer of the bamboo core 6. Since the outer dense layer of the bamboo core 6 is wax liquid, the wax liquid can solidify quickly when it is cooled, and the wax liquid will penetrate into the interior of the flexible fabric core. The fans will not damage the outer dense layer when cooling, so that the outer dense layer can be cooled and shaped quickly.

[0039] In this embodiment, the receiving device can be a frame-type container, and the receiving device can be placed below the end of the cooling mechanism 5 of the transmission chain 25.

[0040] In this embodiment, the mounting groove 21 is located at one end of the base frame 11, the transport gear 24 and the transmission chain 25 are located on one side of the width direction of the base frame 11, and a set of transport gears 24 is also provided at the end of the base frame 11 away from the mounting groove 21. The transmission chain 25 is connected to the transport wheels 24 at both ends of the base frame 11, thereby realizing the transport of bamboo core 6 from the hopper 22 to the end where the cooling mechanism 5 is located.

[0041] In this embodiment, two parallel transmission chains 25 are provided on the base frame 11. The two transmission chains 25 together support one end of the bamboo core 6 and drive one end of the bamboo core 6 to move, so that the other end of the bamboo core 6 passes through the core-adding mechanism 3, the waxing mechanism 4 and the cooling mechanism 5 in sequence.

[0042] In this embodiment, the hopper 22 is located at the top of one end of the mounting groove 21, and the bottom plate of the hopper 22 is arc-shaped. Bamboo cores 6 are stacked inside the hopper 22 along the width of the mounting groove 21. The bamboo cores 6 automatically accumulate towards the lowest point of the hopper 22 due to gravity. The height of the shaft of the feeding gear 23 is lower than the height of the outlet of the hopper 22 (e.g., ...). Figure 3 As shown, when the feeding gear 23 rotates, the portion of the tooth profile of the feeding gear 23 located inside the hopper 22 will lift upwards and drive the bamboo core 6 away from the hopper 22.

[0043] In this embodiment, as Figure 2 As shown, there are two sets of feeding gears 23, which are staggered and have overlapping tooth profiles. The transport gear 24 is staggered with the nearest feeding gear 23, and its tooth profile also overlaps. During feeding, the feeding gear 23 at the end of the hopper 22 rotates counterclockwise, which lifts the bamboo core 6 in the hopper 22 by the tooth groove of the feeding gear 23. When it rotates to the part that overlaps with the other set of feeding gears 23, the other feeding gear 23 transfers the bamboo core 5 to the transmission chain 25 on the transport gear 24, so that the bamboo core 6 enters the groove formed between two adjacent limiting elements 251 on the transmission chain 25.

[0044] In this embodiment, the space of the tooth groove of the feeding gear 23 and the groove formed by two adjacent limiting elements 251 on the transmission chain 25 can only accommodate a single bamboo core 6 at a time (e.g., Figure 6 (As shown). This effectively prevents multiple bamboo cores 6 from being transmitted at once, thereby preventing a single bamboo core 6 from entering the core-adding mechanism 3 and the waxing mechanism 4, and effectively ensuring that the flexible fabric layer and the outer dense layer on the bamboo core 6 are completely and evenly covered.

[0045] In this embodiment, in order to prevent the bamboo core 6 from breaking due to jamming when the two adjacent sets of feeding gears 23 are transmitting bamboo core 6, the edges of the teeth of the feeding gear 23 and the limiting element 251 of the transmission chain 25 that contact the bamboo core 6 should be rounded.

[0046] In this embodiment, as Figures 4-6 As shown, a friction transmission rod 26 is arranged parallel above the transmission surface of the transmission chain 25. A flexible contact layer 261 is provided at the bottom of the friction transmission rod 26. The flexible contact layer 261 is used to contact and drive the bamboo core 6 to rotate.

[0047] Specifically, the friction drive rod 26 is installed below the top mounting bracket 13, and the distance between the flexible contact layer 261 and the drive chain 25 is less than the diameter of a single bamboo core 6. This allows the bamboo core 6 to come into close contact with the flexible contact layer 261 after entering below the friction drive rod 26, thereby generating friction. As the drive chain 25 continues to drive the bamboo core 6 linearly, the friction of the flexible contact layer 261 causes the bamboo core 6 to roll on the drive chain 25. This allows the other end of the bamboo core 6 to be more evenly covered by the flexible fabric layer in the core-upper mechanism 3, and the bamboo core 6 to be more evenly coated with wax liquid in the dense layer inside and outside the waxing mechanism 4. At the same time, it allows the bamboo core 6 to be cooled more evenly and faster in the cooling mechanism 5.

[0048] In this embodiment, the end of the friction transmission rod 26 should be provided with a guide structure, such as a rounded corner or a wedge-shaped surface, so that the bamboo core 6 can normally enter below the flexible contact layer 261.

[0049] In this embodiment, the flexible contact layer 261 is made of a material that is softer and more wear-resistant than the bamboo core 6, such as silicone or rubber. This allows the flexible contact layer 261 to press against the bamboo core 6 by generating elastic deformation, while not hindering the bamboo core 6 from rolling in the groove formed between two adjacent limiting elements 251.

[0050] In this embodiment, as Figure 4 and Figure 5As shown, the upper core mechanism 3 includes a fabric breaking element and a negative pressure traction chamber 34. The fabric breaking element is installed directly above the negative pressure traction chamber 34. A first mesh plate 321 is provided at the bottom of the fabric breaking element, and a second mesh plate 341 is provided at the top of the negative pressure traction chamber 34. The fabric breaking element is used to break the fabric into flocculent material, and the negative pressure traction chamber 34 is used to create negative pressure and pull the flocculent fabric through the first mesh plate 321 and the second mesh plate 341 into the negative pressure traction chamber 34. The end of the bamboo core 6 away from the transmission chain 25 passes through the gap between the first mesh plate 321 and the second mesh plate 341 and is wrapped with flocculent fabric.

[0051] In this embodiment, the flexible fabric core covering the surface of the bamboo core 6 is made of cotton. Correspondingly, the fabric crushing element is a cotton crusher, which should at least include a feed inlet 31, a crushing chamber 32, and crushing blades 33. The crushing chamber 32 is located on the top surface of the base frame 11 near the mounting groove 21, and is situated on one side of the transmission chain 25. A funnel-shaped feed inlet 31 is provided at the top of the crushing chamber 32. A clump of cotton fabric is fed into the crushing chamber 32 through the feed inlet 31. The crushing blades 33 are located inside the crushing chamber 32, breaking the clump of cotton into fine flocs, allowing the cotton to pass through the mesh holes on the first mesh plate 321 and the second mesh plate 341.

[0052] It should be noted that cotton crushers and other fabric crushing mechanisms are commercially available products, and their specific structures and working principles will not be elaborated here (the structure of crushing blades, etc., can be referred to, for example, the utility model patent with publication number CN 111545309 A).

[0053] In this embodiment, an air outlet pipe 342 is provided at the bottom of the negative pressure traction chamber 34, and a negative pressure fan (not shown in the figure) is provided at the other end of the air outlet pipe 342. The air pressure fan continuously discharges air from the negative pressure traction chamber 34 through the air outlet pipe 342, making the air velocity in the negative pressure traction chamber 34 greater than that in the crushing chamber 32, and making the air pressure in the negative pressure traction chamber 34 lower than that in the crushing chamber 32. This allows the flocculent fabric in the crushing chamber 32 to be drawn through the first mesh plate 321 and the second mesh plate 341. When one end of the bamboo core 6 passes between the first mesh plate 321 and the second mesh plate 341, the flocculent fabric covers and adheres to the bamboo core 6. Since the bamboo core 6 rotates during movement, the flexible fabric layer covering the circumference of the bamboo core 6 can be made more uniform.

[0054] Meanwhile, in order to ensure that the fabric can adhere to the bamboo core 6, in this embodiment, a wetting mechanism is provided between the feeding mechanism 2 and the core loading mechanism 3.

[0055] like Figure 4 and Figure 5As shown, the wetting mechanism includes a water inlet pipe 14 and a wet wipe 15 mounted on the top mounting bracket 13, both located above the transmission chain 25. The top of the wet wipe 15 is fixed, and its bottom end contacts the end of the bamboo core 6 furthest from the transmission chain 25. When the transmission chain 25 moves the bamboo core 6, the end of the bamboo core 6 furthest from the transmission chain 25 contacts the wet wipe 15, thus wetting one end of the bamboo core 6. This allows the fuzzy fabric in the upper core mechanism 3 to better adhere to the bamboo core 6 when it comes into contact with it. The water inlet pipe 14 is connected to an external water source and water replenishment is controlled by a solenoid valve. Since the water requirement for wetting the bamboo core 6 is small, the wet wipe 15 can be continuously replenished with moisture by dripping a measured amount of water. Furthermore, the other end of the bamboo core 6 only contacts the wet wipe 15 when one end of the bamboo core 6 enters between the friction transmission rod 26 and the transmission chain 25.

[0056] In this embodiment, as Figures 1-11 As shown, the waxing mechanism 4 includes a wax tray 41 and a pressure plate 42; the top surface of the wax tray 41 is provided with a wax inlet pipe 411 and a wax accumulation tank 413, the wax inlet pipe 411 is used to input wax into the wax accumulation tank 413; the pressure plate 42 is movably installed above the wax accumulation tank 413, and the pressure plate 42 is used to press down one end of the bamboo core 6, so that the flexible fabric core of the bamboo core 6 enters the wax accumulation tank 413 and is coated with wax.

[0057] Specifically, the wax inlet pipe 411 is located on the side of the wax tray 41 near the upper core mechanism 3, and the wax inlet pipe 411 has several wax outlets 412, which are evenly distributed along the length of the wax accumulation tank 413. The inlet end of the wax inlet pipe 411 is connected to a liquid pump (not shown in the figure), which is used to transport liquid wax into the wax accumulation tank 413.

[0058] In this embodiment, the wax tray 41 is also connected to a wax discharge pipe 43. The wax discharge pipe 43 is used to collect the wax flowing out of the wax tray 41 and discharge it. The wax discharge pipe 43 is a semi-circular pipe with its top surface flush with the bottom surface of the wax accumulation tank 413, so that the wax in the wax accumulation tank 413 can flow normally into the wax discharge pipe 43, so that the wax can be collected by the wax discharge pipe 43 and guided to the liquid pump for recycling.

[0059] In other embodiments, the wax discharge tube 43 can be a complete circular tube with a notch on the side near the wax accumulation tank 413, so that the interior of the wax discharge tube 43 is connected to the wax accumulation tank 413. The circular tube can avoid the problem of excessive wax overflow compared to the semi-circular tube.

[0060] In this embodiment, as Figures 8-11As shown, the pressure plate 42 has an arc shape, and a mounting shaft 421 is provided on the side of the pressure plate 42 near the upper core mechanism 3. Both ends of the mounting shaft 421 are rotatably mounted in the mounting arm 422. The top end of the mounting arm 422 is mounted on the top mounting bracket 13, and the bottom end of the mounting arm 422 is hinged to the mounting shaft 421, so that the pressure plate 42 can rotate around the mounting shaft 421.

[0061] Meanwhile, the protruding part of the bottom surface of the pressure plate 42 sinks into the wax accumulation tank 413, so that the bottom of the pressure plate 42 will also be covered with wax. When the end of the bamboo core 6 with the flexible fabric core is transmitted to the position of the pressure plate 42 by the transmission chain 25, the bamboo core 6 will be slightly deformed and bent at the end away from the transmission chain 25 under the action of the gravity of the pressure plate 42 and the guiding action of the arc bottom surface. This allows the flexible fabric core of the bamboo core 6 to be immersed in the wax in the wax accumulation tank 413. The bamboo core 6 will rotate under the action of friction between the transmission rod 26 and the transmission chain 25, so that the surface of the flexible fabric core on the bamboo core 6 can fully contact the wax, making the waxing more uniform. Furthermore, since the mounting shaft 421 of the pressure plate 42 can rotate, the pressure plate 42 can rotate around the mounting shaft 421 when the bamboo core 6 passes its bottom end, thereby preventing the bamboo core 6 from breaking.

[0062] In this embodiment, a first heating element 414 is provided on the bottom surface of the wax tray 41; a second heating element 423 is provided on the pressure plate 42. The first heating element 414 keeps the wax in the wax accumulation tank 413 in a liquid state and prevents it from solidifying by heating. At the same time, the pressure plate 42 is provided with the second heating element 423, which prevents wax from solidifying and adhering to the pressure plate 42.

[0063] In this embodiment, the first heating element 414 and the second heating element 423 are both metal blocks with mounting holes. The mounting holes of the metal blocks are used to install electric heating tubes. The metal blocks are welded to the bottom of the wax liquid support plate 41 and the top of the pressure plate 42.

[0064] Since the bamboo core 6 is usually a long strip of bamboo product, in order to prevent the bamboo core 6 from breaking when passing through the wax accumulation groove 413 because it cannot lift the pressure plate 42, the size and material of the pressure plate 42 and the second heating element 423 should be appropriately selected; at the same time, a bearing can also be set at the connection between the mounting shaft 421 and the mounting arm 422, so that the rotation of the pressure plate 42 is more sensitive.

[0065] It should be noted that in this utility model, the material of the bamboo core 6 is not limited to bamboo products, and other conventional replacements should also be within the protection scope of this utility model.
