Description

Technical Field

[0001] The utility model relates to the technical field of liquor brewing, in particular to a combined liquor mash sampler. Background Art

[0002] In the process of liquor brewing, in order to accurately control the quality of liquor and deeply study the changes in the physical and chemical properties of fermented mash samples during the brewing process (such as physical and chemical indicators such as moisture, acidity, reducing sugar, starch, etc.), as well as the dynamic evolution of flavor components and microbial communities, it is necessary to implement precise sampling at a fixed time, fixed point, and fixed depth. However, the sampling tools currently widely used, such as soil drills or electric soil drills, all adopt a layer-by-layer collection method from the outside to the inside to reach the preset depth of the pile. This sampling method may result in low sampling accuracy and difficulty in achieving true in-situ sampling. In addition, the existing soil samplers are mainly designed for soil characteristics, and fermented mash, as a unique medium, has internal structure, surface friction, and easy collapse properties that are completely different from soil, which further affects the accuracy of sampling and the convenience of operation. A new type of fermented mash sampling device is urgently needed to solve such technical problems.

[0003] The patent document of CN116539349A proposes a white wine mash sampler, which includes a central shaft, a spiral blade, a sleeve, a fixed disc, a handle, a temperature probe, a wire, a sawtooth structure, and a temperature display. The characteristics are as follows: the spiral blade is fixed on the lower side of the central shaft, the fixed disc is fixed on the upper side of the central shaft, the upper end of the central shaft is located above the fixed disc and connected to the handle, the top of the central shaft is connected to the temperature display, the sleeve and the fixed disc are screwed together by internal and external threads; the central shaft is a hollow structure, the lower end is a closed tip, a temperature probe is arranged in the cavity of the lower tip, the temperature probe is connected to the temperature display through a wire, the bottom end of the sleeve is a sawtooth structure, the upper end of the sleeve is connected to the fixed disc by internal and external threads, and the tip is located below the sawtooth structure. The mash sampler aims to increase the amount of mash collected in a single time through the synergistic effect of the spiral blade and the sleeve. However, in actual operation, when the sampler gradually penetrates into the mash pile, the reaction force generated by the mash on the spiral blade significantly increases the difficulty of manual operation, making the insertion process laborious. In addition, since some non-target mash has been mixed into the gap between the sleeve and the spiral blade before the sampler reaches the predetermined sampling point, this phenomenon seriously interferes with the sampler's in-situ precise sampling function, resulting in deviations in the sampling results.

[0004] In addition, on the one hand, there are differences in understanding among technical personnel in this field; on the other hand, the applicant studied a large number of documents and patents when making the present utility model, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present utility model does not have the characteristics of these prior arts. On the contrary, the present utility model already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application proposes a combined liquor lees sampler, in particular, a combined liquor lees sampler that can realize multiple precise point sampling, aiming to solve one or more technical problems in the prior art.

[0006] The mash samplers in the prior art have a relatively simple sampling tool and are limited by the structure of the tool itself, resulting in insufficient sampling accuracy, which to a certain extent affects the analysis and research of mash samples. In addition, the existing samplers mostly use soil drills or electric soil drills, and the adaptability of such tools to the characteristics of mash is not ideal. As a unique substance, mash has obvious differences in properties and characteristics from other soils. Therefore, in practical applications, the existing mash samplers are often difficult to meet the sampling needs. In addition, the existing mash samplers are directly inserted into the mash for sampling, and may encounter greater resistance when entering the mash, especially if the mash is relatively dry, hard or sticky. This will require the operator to apply more force to sample, which is time-consuming and laborious.

[0007] In order to facilitate the sampling of solid mash at a specific location, a liquor solid mash sampling device with a sleeve structure has appeared in the prior art. For example, the patent document with the publication number CN215065366U discloses a liquor solid mash sampling device, including a sleeve, a matching component that can be inserted into the sleeve, and a sampling component. The matching component has a matching body that matches the inner diameter of the sleeve, so that when the sleeve is inserted into the mash, the lower end of the sleeve is blocked by the matching body, and the sampling component is used to pass through the sleeve to sample the mash at the lower end of the sleeve. The liquor solid mash sampling device of this technical solution can be easily drilled into the mash part that needs to be sampled, and during the sampling process, mash from other parts will not be mixed, making the sampling structure more accurate. However, the sleeve structure in this technical solution does not have a breakthrough structure that allows it to be inserted into the interior of the mash. Especially when the solid mash is highly viscous and has less water, the insertion of the sleeve structure itself will result in great resistance at its front end, making the sampling process of the sleeve structure also time-consuming and laborious.

[0008] Therefore, in order to solve the above-mentioned technical problems, the utility model proposes a combined white wine mash sampler, which includes: an outer rod, an inner rod and a sampling rod. The outer rod is placed in the mash pile in combination with the inner rod, and the sampling rod takes out the mash sample from the mash pile in the form of replacing the inner rod and the outer rod in combination. The surface of the outer rod is provided with a rotating support, and the rotating support can move on the surface of the outer rod to partially insert into the mash pile after the outer rod is placed in the mash pile and prevent the outer rod from continuing to move.

[0009] In order to improve the efficiency of the sampling device inserted into the fermented grains sample, a drilling device with a twist drill bit has appeared in the prior art. For example, the patent document with publication number CN201876372U discloses a wine lees sampler, including a drilling rod and a sampling rod, wherein the drilling rod includes a twist drill bit and a drilling rod rotating handle connected to the tail of the twist drill bit, and the sampling rod includes a U-shaped groove drill bit and a sampling rod rotating handle connected to the tail of the U-shaped groove drill bit, and the outer diameters of the drilling rod rotating handle and the sampling rod rotating handle are both less than or equal to the corresponding drill bit outer diameter. The technical solution first drills a hole through the drilling rod, and then samples through the sampling rod. The drill bit has a small outer diameter, which can avoid bringing a large amount of air and bacteria into the cellar when entering the cellar, causing infection of the wine lees. However, the thread-like structure in the technical solution is only arranged at the end of the drilling rod, so it can only be used to push the fermented grains away from its path of travel, so that the drilling rod can easily move along its axial direction, thereby improving the efficiency of the drilling rod entering the fermented grains. Since the outer wall of the drilling rod is a smooth surface, its stability in the mash is poor and it cannot provide stable support for mash sampling in a specific area. Compared with the above-mentioned prior art, the outer wall surface of the outer rod in the utility model is configured with a rotating support with an adjustable position. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to improve the stability of the outer rod after it enters the mash, so as to prevent the end of the outer rod from being displaced inside the mash and causing inaccurate sampling. Specifically, the rotating support configured on the outer wall surface of the outer rod can move toward the surface of the mash pile after the outer rod enters the mash, and provide an auxiliary fixing effect for the outer rod by being inserted into the mash pile, thereby improving the accuracy of the sampling position.

[0010] According to a preferred embodiment, the outer rod is provided with a hollow tubular first rod body with both ends open and a first handle arranged at the proximal end of the first rod body, and the surface of the first rod body is provided with an external thread for conveniently screwing the outer rod into the mash pile, and a threaded connection is formed between the rotating support and the external thread. The rotating support comprises a threaded sleeve sleeved on the first rod body, and the inner wall of the threaded sleeve is provided with an internal thread meshed with the external thread, so that the rotating support can make a spiral motion with the first rod body as the axis to approach or move away from the first handle. The configured first handle can be convenient for the operator to grasp, and is convenient for the outer rod to be rotated into and out of the mash pile. The outer wall surface of the outer rod is provided with external threads, and these thread designs make it easier for the first rod body to be screwed into the mash pile, and can also be easily detached from the mash pile by reverse rotation. The mash pile is usually composed of fermented materials, and has a certain viscosity and consistency, and the existence of the external threads increases the friction between the outer rod and the mash pile, so that the outer rod can be more stably fixed in the mash pile, and is not easy to slip or loosen. The external thread on the surface of the outer rod not only improves the stability of the outer rod after it is screwed into the mash pile, but can also be connected with the thread of the rotating support so that the rotating support can move with the help of the external thread. The movement of the rotating support toward the mash pile can make it partially immersed in the mash pile, which provides further guarantee for the fixed position of the outer rod.

[0011] According to a preferred embodiment, the rotating support includes a plurality of legs connected to the circumferential outer wall of the threaded sleeve, the legs are bent away from the ends of the threaded sleeve to form a needle, and the needle has an orientation that conforms to the rotation direction of the threaded sleeve when the rotating support moves toward the distal end of the outer rod, so that it can be immersed in the surface of the mash pile. The legs provide a stable structural foundation to ensure that the rotating support can stably establish a fixed relationship with the mash pile. In addition, because the orientation of the needles is consistent with the moving direction of the rotating support, they can cut through the surface of the mash pile when rotating in, rather than simply pushing. This cutting and insertion method greatly reduces the pressure and damage caused to the mash pile, while improving the insertion efficiency and accuracy.

[0012] According to a preferred embodiment, a magnetic patch is disposed at one end of the threaded sleeve close to the first handle, so that the rotating support can be maintained in the initial position by magnetically adsorbing the first handle. The adsorption connection achieved by the magnetic patch allows the rotating support to be easily connected to or separated from the first handle. The operator does not need to physically lock the rotating support through a complex mechanical structure, which simplifies the operation of keeping the rotating support in the initial position before it is actively moved, and at the same time avoids the movable rotating support from affecting the process of placing the outer rod into the mash pile.

[0013] According to a preferred embodiment, the rotating support is detachably mounted on the first rod body, and a buffer zone without threads is arranged near the distal end of the first rod body at the position of the external thread, so as to reduce the impact force when the rotating support is separated from the distal end of the first rod body. When the rotating support is separated from the first rod body, the force required to be applied by the operator is reduced due to the non-threaded arrangement of the buffer zone, so that the rotating support can slide over the last distance more easily, thereby reducing the physical labor of the operator.

[0014] According to a preferred embodiment, the inner rod is detachably connected to the outer rod. When the inner rod is connected to the outer rod, the inner rod blocks the distal end of the outer rod to prevent the mash from entering the outer rod; when the inner rod is pulled out of the outer rod, the sampling rod is inserted into the outer rod to obtain the mash sample through the sampling channel formed by the outer rod. The utility model provides a stable and reliable sampling channel for the sampling process by placing the outer rod into the mash pile, so that when the operator performs multiple samplings on the same sampling point, it is not necessary to frequently pull out and plug the entire sampler, and the sampling rod can be completed by reciprocating in the sampling channel, thereby avoiding the collapse of the mash. In addition, the detachable connection design between the inner rod and the outer rod enables the inner rod to effectively block the opening of the outer rod when the outer rod is placed into the mash pile, preventing non-target mash from entering the outer rod. This design ensures that each sampling only involves samples of the target sampling point, thereby significantly improving the purity of the sample.

[0015] According to a preferred embodiment, the inner rod includes a second rod body and a second handle located at the proximal end of the second rod body and connected to the second rod body. When the inner rod is connected to the outer rod, a threaded drill bit arranged at the distal end of the second rod body extends out of the opening at the distal end of the first rod body. Compared with the above-mentioned prior art, the inner rod structure in the utility model is provided with a threaded drill bit for blocking the distal opening of the first rod body. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to provide guidance for the drilling of the outer rod and improve its efficiency of entering the interior of the mash. Specifically, the threaded drill bit on the second rod body of the utility model is roughly conical, and this design plays a guiding role when the outer rod is placed in the mash pile. The conical shape can reduce the resistance during placement, making it easier for the outer rod to be screwed into the mash pile. At the same time, the threaded drill bit can provide additional support and guidance when the outer rod rotates, which helps the stable placement of the outer rod. When the inner rod is rotatably connected with the outer rod, the threaded drill bit can tightly block the distal opening of the first rod body (outer rod). This design can prevent the mash other than the sampling point from entering the inner tube, ensuring that only the sample at the target sampling point is taken out. This arrangement can improve the purity and accuracy of the sample and avoid contamination of the sample by other non-target mash. Preferably, the tail thread of the threaded drill bit on the second rod body away from its tip matches the external thread on the outer rod. Through the above arrangement, the mash drilled by the threaded drill bit can be seamlessly connected along the external thread on the outer rod, thereby improving the integrity of the mash during the drilling process, preventing the accumulation of mash due to inconsistent threads, and stirring the mash to affect the accuracy of its initial distribution.

[0016] According to a preferred embodiment, the sampling rod includes a third rod body and a third handle located at the proximal end of the third rod body and connected to the third rod body, and the distal end of the third rod body is provided with a sampling drill bit for sampling the mash, and the sampling drill bit is provided with a sampling groove for accommodating the mash sample. With the aid of the sampling drill bit, the third rod body can be more easily inserted into the mash pile, thereby facilitating the acquisition of samples from the target sampling point. The design of the sampling groove allows the acquired samples to be conveniently transferred from the sampling drill bit to other containers or equipment for subsequent analysis or processing.

[0017] According to a preferred embodiment, the rod surfaces of the first rod body and the third rod body have a scale indicating the depth of the sampling point, and the zero scale of the scale is located at the opening at the distal end of the first rod body and the tip of the sampling drill at the distal end of the third rod body. The existence of the scale allows the operator to intuitively understand the depth of the sampling point. By observing the reading on the scale, the operator can accurately know the depth to which the sampling drill has penetrated into the mash pile, which is particularly suitable for application scenarios where the sampling depth needs to be precisely controlled.

DETAILED DESCRIPTION

[0027] The utility model is described in detail below in conjunction with the accompanying drawings.

[0028] Definition of orientation: The end of the sampler that is closer to the operator during use is the proximal end, and the end that is farther away from the operator is the distal end.

[0029] like Figure 1 , Figure 4 and Figure 5As shown, the utility model relates to a combined white wine lees sampler, which aims to provide an efficient, convenient, accurate and labor-saving lees sampling tool, which includes an outer rod 100 for being placed in a lees pile to provide a stable sampling channel, an inner rod 200 for being inserted into the outer rod 100 to assist the placement of the outer rod 100, and a sampling rod 300 for taking out a lees sample from a sampling point of the lees pile. In the actual process of sampling the lees pile, the outer rod 100 and the inner rod 200 can be assembled to form a complete rod-shaped component that reaches the target sampling point inside the lees pile. When the depth of the rod-shaped component inserted into the lees pile meets the sampling requirements, the inner rod 200 is taken out of the outer rod 100, and the sampling rod 300 is extended into the stable sampling channel formed by the outer rod 100 to scrape or dig the lees sample at the sampling point, and then the sample can be taken out of the lees pile.

[0030] Preferably, if Figure 2 As shown, the outer rod 100 includes a first rod body 110 and a first handle 120. The first rod body 110 is designed as a hollow tube with openings at both ends. Such a design not only ensures that it can be inserted into the mash pile and take out samples, but also provides space for the insertion of the inner rod 200. The first handle 120 is arranged at the proximal end of the first rod body 110, which is convenient for users to hold and operate. Preferably, a hole is left on the first handle 120 that runs through itself, and the hole is connected to the opening at the proximal end of the first rod body 110, so that the inner rod 200 or the sampling rod 300 can be extended into the outer rod 100 from the hole. In addition, in order to facilitate the first rod body 110 to be placed in the mash pile, the outer wall surface of the hollow tube is configured with external threads 130, which not only facilitate the screwing of the first rod body 110, but also enhance the friction between it and the mash pile, preventing it from sliding or loosening during the sampling process.

[0031] Preferably, if Figure 2 , Figure 3 As shown, the inner rod 200 includes a second rod body 210 and a second handle 220, wherein the second handle 220 is disposed at the proximal end of the second rod body 210, and the distal end of the second rod body 210 is provided with a threaded drill bit 230 for blocking the distal end opening of the first rod body 110. When the inner rod 200 is connected to the outer rod 100, the threaded drill bit 230 disposed at the distal end of the second rod body 210 extends out of the distal end opening of the first rod body 110. The second handle 220 is convenient for the user to hold and operate, and the threaded drill bit 230 can use its conical bottom to fit the distal end opening of the first rod body 110 to seal the internal space of the first rod body 110, thereby preventing the mash from entering. In addition, the threaded drill bit 230 can provide additional support and guidance when the first rod body 110 rotates, which helps to stably place the outer rod 100.

[0032] Preferably, if Figure 2 , Figure 3As shown, the inner wall of the opening near the distal end of the first rod body 110 is provided with a socket thread 140, which can be engaged with a socket thread 240 provided on the second rod body 210 near the threaded drill bit 230. The detachable connection between the first rod body 110 and the second rod body 210 is achieved by the mutual cooperation of the socket thread 140 and the socket thread 240. Threaded connection is a commonly used connection method, which has high connection strength and stability. Such a design enables the inner rod 200 to be firmly inserted and connected to the outer rod 100.

[0033] Preferably, if Figure 1 , Figure 2 As shown, a rotating support 150 threadedly connected to the external thread 130 on the surface of the outer rod 100 is provided. After the outer rod 100 is screwed into the mash pile, the rotating support 150 is located outside the mash pile. The rotating support 150 includes a threaded sleeve 151 and a plurality of legs 152 connected to the circumferential outer wall of the threaded sleeve 151. The circumferential inner wall of the threaded sleeve 151 is provided with an internal thread engaged with the external thread 130. The legs 152 are bent away from the ends of the threaded sleeve 151 to form a thorn 153. The thorn 153 has an orientation that conforms to the rotation direction of the threaded sleeve 151 when the rotating support 150 moves toward the distal end of the outer rod 100, so that it can be immersed in the surface of the mash pile. "Conforming to" the rotation direction does not mean that it is exactly the same as the rotation direction, but that the thorn 153 can be fixed in accordance with the rotation direction of the threaded sleeve 151 to cooperate with the rotating support 150. Exemplarily, when the rotating support 150 rotates clockwise, it can move toward the distal end of the outer rod 100 (i.e., away from the first handle 120), and the direction of the needle 153 of the support leg 152 is also approximately clockwise. Since the rotating support 150 can move along the surface of the outer rod 100, after the outer rod 100 is screwed into the mash pile, the needle 153 of the support leg 152 can be inserted into the mash pile to prevent the outer rod 100 from moving further. The direction of the needle 153 allows it to be rotated and inserted into the mash pile in the form of a certain inclination angle with the surface of the mash pile. Compared with inserting in a vertical form, such a setting can significantly reduce the impact of the unstable fixation of the needle 153 due to the possible presence of voids on the surface of the mash pile.

[0034] Preferably, a magnetic patch is provided at one end of the threaded sleeve 151 close to the first handle 120, so that the threaded sleeve 151 of the rotating support 150 can be magnetically connected to the first handle 120 when the outer rod 100 is idle or is being screwed into the mash pile to maintain a stable position. The rotating support 150 is connected to the first handle 120 by adsorption through the magnetic patch, so that the rotating support 150 can be easily connected to or separated from the first handle 120. The operator does not need to physically lock it through a complex mechanical structure, thereby simplifying the operation of keeping the rotating support 150 in the initial position (i.e., the rotating support 150 is magnetically adsorbed to the position of the first handle 120) before it is actively moved, and at the same time avoiding the movable rotating support 150 from affecting the process of placing the outer rod 100 into the mash pile.

[0035] Preferably, the rotating support 150 is detachably mounted on the first rod 110, and a buffer zone without threads is arranged near the distal end of the first rod 110 of the external thread 130, so as to reduce the impact force when the rotating support 150 is separated from the distal end of the first rod 110. The setting of the buffer zone can reduce the damage to the rotating support itself and the first rod caused by the impact force generated when the rotating support is separated from the distal end of the first rod, thereby extending the service life of the equipment. In addition, when the rotating support is separated from the first rod, the force required to be applied by the operator will be reduced due to the non-threaded setting form of the buffer zone, so that the rotating support can slide through the last distance more easily, thereby reducing the physical labor of the operator. Preferably, the external thread 130 and the socket thread 240 have opposite screwing directions, ensuring that the rotation direction of the first rod 110 screwed into the mash pile is opposite to the rotation direction when the second rod 210 and the first rod 110 are threadedly connected. This design takes into account the mechanical factors in actual operation, that is, under the condition of the same travel distance, the forward rotation force required for the outer rod 100 to penetrate into the mash pile is significantly greater than the reverse rotation force required for it to retreat from the mash pile. If the rotation direction of the threaded connection between the second rod body 210 and the first rod body 110 is the same as the rotation direction of the first rod body 110 screwed into the mash pile, then when the threaded connection between the two is released, the reverse rotation of the second rod body 210 may drive the first rod body 110 to rotate together. Since the resistance that the mash pile can apply to the external thread 130 of the outer wall of the first rod body 110 in the reverse rotation direction of the first rod body 110 is relatively small, the first rod body 110 is more easily driven by the second rod body 210 to rotate and retreat from the mash pile, thereby affecting the stability of the first rod body 110 in the mash pile. On the contrary, if the rotation direction of the threaded connection between the second rod body 210 and the first rod body 110 is set to be opposite to the rotation direction of the first rod body 110 screwing into the mash pile, when the second rod body 210 is screwed out, the mash pile in the positive rotation direction of the first rod body 110 can exert a greater resistance on the outer thread 130 of the outer wall of the first rod body 110, so that the first rod body 110 is more difficult to be driven by the second rod body 210 to rotate and penetrate into the mash pile, thereby maintaining stability and avoiding position fluctuations. In addition, the rotating support 150 provides an additional fixing effect in this process, so that when the second rod body 210 is disconnected from the first rod body 110, unnecessary rotation or displacement of the first rod body 110 is avoided, thereby ensuring the integrity and accuracy of the sampling. This design ensures that the depth of the first rod body 110 in the mash pile is stable, thereby improving the accuracy of the sampling point.

[0036] Preferably, if Figure 2 , Figure 3As shown, the sampling rod 300 includes a third rod body 310 and a third handle 320 located at the proximal end of the third rod body 310 and connected to the third rod body 310. The distal end of the third rod body 310 is provided with a sampling drill bit 330 for sampling fermented grains, and the sampling drill bit 330 is provided with a sampling groove for accommodating the fermented grains sample. With the aid of the sampling drill bit 330, the third rod body 310 can be more easily inserted into the fermented grains pile, so as to facilitate obtaining samples from the target sampling point. The design of the sampling groove allows the obtained samples to be conveniently transferred from the sampling drill bit 330 to other containers or equipment for subsequent analysis or processing. Preferably, the sampling rod 300 can directly select the sampler commonly used in the existing fermented grains sampling tool, and only needs to meet the length and diameter required by the utility model. Preferably, the inner diameter of the first rod body 110 is greater than the outer diameters of the second rod body 210 and the third rod body 310 , so that the inner rod 200 and the sampling rod 300 can be inserted into or removed from the outer rod 100 .

[0037] Preferably, the rod surfaces of the first rod body 110 and the third rod body 310 have a scale indicating the depth of the sampling point, and the zero mark of the scale is located at the opening at the distal end of the first rod body 110 and the tip of the sampling drill bit 330 at the distal end of the third rod body 310. Such a design allows the operator to intuitively understand the depth of the sampling point by observing the readings on the scale, which is particularly suitable for application scenarios where the sampling depth needs to be accurately controlled.

[0039] S1, insert the inner rod 200 into the outer rod 100, so that the threaded drill bit 230 at the distal end of the inner rod 200 extends out of the distal end opening of the outer rod 100;

[0040] S2, screwing the inner rod 200 so that it is threadedly connected with the outer rod 100 to form a combined rod;

[0041] S3, rotating the combined rod at a suitable angle and placing it in the mash pile, observing the scale on the outer rod 100 to make the distal end of the rod reach the sampling point at a predetermined depth of the mash pile, and rotating the rotating support 150 toward the mash pile so that the support leg 152 is immersed in the mash pile;

[0042] S4, rotating the inner rod 200 to remove the outer rod 100, and leaving the outer rod 100 in the mash pile;

[0043] S5, inserting the sampling rod 300 into the mash pile through the hollow channel of the outer rod 100, observing the scale on the sampling rod 300 to make the sampling drill bit 330 of the sampling rod 300 reach the sampling point at a predetermined depth of the mash pile, and scraping or digging the mash sample;

[0044] S6, taking out the sampling rod 300, and removing the fermented grains sample from the sampling drill bit 330 (steps S5 and S6 may be performed multiple times according to the required number of fermented grains samples);

[0045] S7, rotating the rotating support 150 and the outer rod 100 in the opposite direction to withdraw from the grains of mash.

[0046] It should be noted that the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model.
