Description

Technical Field

[0001] This utility model relates to the field of food testing devices, and more specifically, to a food testing sampler. Background Technology

[0002] When conducting random inspections of food quality, it is usually necessary to use a sampler to collect a portion of the food for testing.

[0003] A search revealed that Chinese patent CN222671489U discloses a "food testing sampler" comprising a sampling tube, a push tube, a push ring, a collar, an adjusting column, and a sampling spoon. The push ring is slidably fitted within the groove, and the inner side of the push ring is connected to the outer wall of the push tube. A collar is fitted onto the outer wall of the sampling tube near the needle tube. An adjusting column is rotatably mounted on the collar, and a sampling spoon is fitted onto the adjusting column. The user can hold the sampling tube with one hand, pressing their thumb against the push ring, allowing precise control of the push ring's movement via the thumb. This enables the push tube and piston head to slide synchronously, achieving convenient single-handed sampling of fluid foods. The sampling spoon is easy to use and its foldable design prevents interference during use, further enhancing convenience for food sampling. However, the following drawbacks remain: (1) The push ring needs to be pressed and slid back and forth with the thumb. If the viscosity of the fluid food is high (such as honey or sauce), a large force is required. Long-term use can easily cause fatigue.

[0004] (2) During the sampling process, the sampling spoon is prone to unexpected flipping due to external force collision, which affects the stability of solid sample collection. At the same time, the sampling spoon is easily contaminated when exposed to the outside, which leads to distorted test results.

[0005] Therefore, a food testing sampler is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a food testing sampler that addresses the problem that the push ring requires pressing and sliding with the thumb, which is necessary for high-viscosity fluid foods (such as honey and sauces) and can lead to fatigue with prolonged use.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a food testing sampler, including a mounting ring, one end of which is fixedly mounted with a liquid extraction component for extracting and testing liquid food, and the other end of which is threadedly mounted with a sampling component for sampling and testing solid food. The liquid extraction assembly includes a push tube fixedly connected to an mounting ring, a push rod fixedly installed at the other end of the push tube, a piston head fixedly connected at the other end of the push rod, a spring provided on the inner side of the piston head, the spring located on the outer side of the push rod and the push tube, a sealing cap fixedly connected at the other end of the spring, a liquid extraction tube fixedly installed on the outer side of the sealing cap, the outer side wall of the piston head sliding against the inner side wall of the liquid extraction tube, and an anti-slip groove provided on the outer side of the liquid extraction tube.

[0008] As a preferred technical solution of this utility model, the sampling component includes a limiting block located on one side of the mounting ring, a sliding rod fixedly connected to one end of the limiting block, a pushing block provided on the sliding rod, a limiting groove opened on the pushing tube, the pushing block sliding through the pushing tube along the limiting groove, and a sampling spoon fixedly installed at the other end of the limiting block.

[0009] As a preferred technical solution of this utility model, a guide tube is provided through the liquid extraction tube, and the other end of the guide tube is connected to a liquid storage tube by a thread. The outer side of the liquid storage tube is provided with scale lines, and one end of the liquid storage tube is connected to a sampling needle tube by a thread.

[0010] As a preferred technical solution of this utility model, a locking block is fixedly installed on the liquid storage tube, and a protective sleeve is movably installed on the locking block, with the protective sleeve located outside the sampling needle tube.

[0011] As a preferred technical solution of this utility model, a protective cover is sleeved on one side of the mounting ring, and the protective cover is located on the outside of the sampling spoon.

[0012] As a preferred technical solution of this utility model, a solid collection box is installed at the other end of the protective cover by a thread, the push tube and the sealing cover are connected through each other, the inside of the push tube is hollow and the slide rod is located inside the push tube.

[0013] As a preferred technical solution of this utility model, the pushing block is located in the middle position between the mounting ring and the sealing cover, and a one-way valve is provided on the guide tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When sampling liquid food, push the push rod to move the piston head inside the liquid extraction tube, compressing the spring and creating a negative pressure inside the tube. The liquid food is then drawn in through the tube. After sampling, release the push rod, the spring returns to its original shape, and the piston head is pushed back to its original position, reducing the need for continuous force. The combination of the spring and the piston head enables rapid extraction and sealing of the liquid. The anti-slip groove design makes it easy for operators to hold the liquid extraction tube, improving sampling stability. 2. When sampling solid food, the operator only needs to push the push block to make it slide smoothly along the limiting groove. The push block will drive the slide rod and the limiting block to move synchronously. As the limiting block moves, the sampling spoon will extend, thus successfully completing the sampling of solid food. After sampling, push the push block in the opposite direction to make the slide rod and the limiting block move in the opposite direction, thereby retracting the sampling spoon into the sampler. This can effectively prevent the sampling spoon from coming into contact with the external environment and becoming contaminated, ensuring the accuracy of subsequent test results.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0018] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] like Figures 1-5 As shown, this embodiment proposes a food testing sampler, including a mounting ring 1. One end of the mounting ring 1 is fixedly mounted with a liquid extraction component 2 for extracting and testing liquid food, and the other end of the mounting ring 1 is threadedly mounted with a sampling component 3 for sampling and testing solid food. The liquid extraction assembly 2 includes a push tube 201 fixedly connected to the mounting ring 1. A push rod 202 is fixedly installed at the other end of the push tube 201. A piston head 203 is fixedly connected to the other end of the push rod 202. A spring 204 is provided on the inner side of the piston head 203. The spring 204 is located on the outer side of the push rod 202 and the push tube 201. A sealing cap 205 is fixedly connected to the other end of the spring 204. A liquid extraction tube 206 is fixedly installed on the outer side of the sealing cap 205. The outer side wall of the piston head 203 slides against the inner side wall of the liquid extraction tube 206. An anti-slip groove 207 is provided on the outer side of the liquid extraction tube 206. When sampling liquid food, pushing the push rod 202 causes the piston head 203 to slide inside the suction tube 206, compressing the spring 204 and creating a negative pressure inside the suction tube 206. The liquid food is then drawn in through the suction tube 206. After sampling, releasing the push rod 202 allows the spring 204 to return to its original shape, pushing the piston head 203 back to its original position, reducing the need for continuous force. The cooperation between the spring 204 and the piston head 203 enables rapid extraction and sealing of the liquid. The anti-slip groove 207 design facilitates the operator's grip on the suction tube 206, improving sampling stability.

[0022] like Figures 1-3 and Figure 5As shown, the sampling component 3 includes a limiting block 301 located on one side of the mounting ring 1. One end of the limiting block 301 is fixedly connected to a slide rod 302. A pushing block 303 is provided on the slide rod 302. A limiting groove 304 is provided on the push tube 201. The pushing block 303 passes through the push tube 201 and slides along the limiting groove 304. A sampling spoon 305 is fixedly installed on the other end of the limiting block 301. When sampling solid food, the operator only needs to push the push block 303 to make it slide smoothly along the limiting groove 304. The push block 303 will drive the slide rod 302 and the limiting block 301 to move synchronously. As the limiting block 301 moves, the sampling spoon 305 extends, thus successfully completing the sampling of solid food. After sampling, push the push block 303 in the opposite direction to make the slide rod 302 and the limiting block 301 move in opposite directions, thereby causing the sampling spoon 305 to retract into the sampler. This can effectively prevent the sampling spoon 305 from coming into contact with the external environment and becoming contaminated, ensuring the accuracy of subsequent test results.

[0023] like Figures 3-5 As shown, a guide tube 208 is threaded through the extraction tube 206, and the other end of the guide tube 208 is connected to a storage tube 209 via a thread. A scale line 210 is provided on the outside of the storage tube 209, and a sampling needle tube 211 is threaded to one end of the storage tube 209. The sampling needle tube 211 draws liquid food, which flows into the storage tube 209 through the guide tube 208. The scale line 210 on the storage tube 209 facilitates observation of the liquid collection volume. After collection, the storage tube 209 can be disassembled and stored separately or sent for testing.

[0024] like Figures 1-4 As shown, a locking block 4 is fixedly installed on the liquid storage tube 209, and a protective sleeve 5 is movably installed on the locking block 4, with the protective sleeve 5 located outside the sampling needle tube 211. When the sampling needle tube 211 is not in use, the protective sleeve 5 is placed on the sampling needle tube 211 to prevent the sampling needle tube 211 from being contaminated or accidentally punctured.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, a protective cover 6 is fitted onto one side of the mounting ring 1, and the protective cover 6 is located on the outside of the sampling spoon 305. When the sampling spoon 305 is not in use, the protective cover 6 is put on to prevent the sampling spoon 305 from being contaminated or damaged, thereby improving the sampling quality.

[0026] like Figures 1-3 and Figure 5As shown, a solid collection box 7 is threaded onto the other end of the protective cover 6. A push tube 201 and a sealing cover 205 are connected through the solid collection box 7. The push tube 201 is hollow, and a sliding rod 302 is located inside the push tube 201. The solid collection box 7 is used to collect solid food samples retrieved by the sampling spoon 305, preventing them from scattering or being contaminated by external factors. The sliding rod 302 can slide within the push tube 201, greatly saving space and making it more convenient to use.

[0027] like Figures 1-5 As shown, the push block 303 is located between the mounting ring 1 and the sealing cover 205, and a one-way valve 8 is installed on the guide pipe 208. The one-way valve 8 can effectively prevent liquid backflow, ensure the accuracy and purity of the sampled liquid, and improve the reliability of the test results.

[0028] Specifically, when using this food testing sampler: When sampling liquid food, pushing the push rod 202 causes the piston head 203 to slide within the extraction tube 206, compressing the spring 204 and creating a negative pressure within the extraction tube 206. The liquid food is then drawn in through the extraction tube 206. After sampling, releasing the push rod 202 allows the spring 204 to return to its original shape, pushing the piston head 203 back to its original position, reducing continuous force. The cooperation between the spring 204 and the piston head 203 enables rapid extraction and sealing of the liquid. The anti-slip groove 207 design facilitates the operator's grip on the extraction tube 206, improving sampling stability. The sampling needle 211 extracts the liquid food, which flows into the storage tube 209 through the guide tube 208. The scale line 21 on the storage tube 209... The liquid collection volume is easily observed. After collection, the liquid storage tube 209 can be disassembled and stored or sent for testing separately. When sampling solid food, the operator only needs to push the push block 303 to make it slide smoothly along the limiting groove 304. The push block 303 will drive the slide rod 302 and the limiting block 301 to move synchronously. As the limiting block 301 moves, the sampling spoon 305 extends, thus successfully completing the sampling of solid food. After sampling, push the push block 303 in the opposite direction to make the slide rod 302 and the limiting block 301 move in opposite directions, thereby causing the sampling spoon 305 to retract into the sampler. This can effectively prevent the sampling spoon 305 from contacting the external environment and being contaminated, ensuring the accuracy of subsequent test results.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
