Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a sampling and storage device for food testing. Background Technology

[0002] As is well known, food testing sampling and storage devices are specialized devices used in the field of food testing to collect different types of food samples (such as solid, liquid, and semi-solid foods) on-site or in the laboratory, and to provide a storage environment that meets testing standards (such as temperature control, sealing, and prevention of contamination) to maintain the original properties and composition of the samples before submission and testing, thereby ensuring the accuracy of subsequent test results. Structurally, they typically include sampling components, storage containers, sealing components, and auxiliary fixing or temperature control components.

[0003] Existing sampling devices can only use sampling blades to sample solid food, and cannot sample liquid food, so their effectiveness is not good. An existing patent (publication number: CN220508430U) discloses a sampling device for food inspection, including a sealed container and a sealing cap used in conjunction with the sealed container. The sealed container has a rotatable test tube rack inside, on which several storage test tubes are placed around the center point of the sealed container for storing food samples. The storage test tubes are arranged vertically, and each storage test tube has a stopper at its opening. Some stoppers have a solid sampling mechanism for picking up solid food, while others have a liquid sampling mechanism for absorbing liquid food. This invention, through the action of the solid and liquid sampling mechanisms, enables the sampling device to sample both solid and liquid foods, thereby improving sampling efficiency.

[0004] To address the aforementioned issues, existing patents have provided solutions. However, when sampling fluid and semi-solid foods, the lack of a structure for quantitative sampling and storage of fluid and semi-solid foods makes it impossible to quantitatively sample them, thus reducing the flexibility in sampling and storing fluid and semi-solid foods.

[0005] Therefore, a sampling and storage device for food testing is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a sampling and storage device for food testing, which can solve the problem that existing sampling devices for fluid and semi-solid foods lack a structure for quantitative sampling and storage of fluid and semi-solid foods, thus reducing the flexibility of sampling and storing fluid and semi-solid foods.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampling and storage device for food testing, comprising a sampling cylinder and a sampling mechanism, wherein the sampling mechanism is located at the bottom of the sampling cylinder; the sampling cylinder comprises a storage tank, a sampling base, a one-way cover, a sampling tube, a sampling needle tube, and a perforated top plate, wherein the sampling base is installed at the bottom of the inner side of the storage tank, the one-way cover is rotatably connected to the output port at the bottom of the inner side of the sampling base, the sampling tube is connected to the input port at the bottom of the sampling base, the sampling needle tube is welded to the bottom of the sampling tube, and the perforated top plate is welded to the top of the storage tank.

[0008] Preferably, the sampling mechanism includes an inhalation component and a pressure control component, wherein the inhalation component is located at the top of the perforated top plate and the pressure control component is located at the bottom of the inhalation component.

[0009] Preferably, the inhalation assembly includes an air cylinder, a piston rod, and a handle. The air cylinder is welded to the top of a perforated top plate, the piston rod is slidably connected to the top of the inner side of the air cylinder, and the handle is welded to the top of the piston rod.

[0010] Preferably, the pressure control assembly includes a rubber plug, an air hole, and a one-way air plate. The rubber plug is bolted to the bottom of the piston rod, the air hole is opened at the top of the rubber plug and penetrates through the rubber plug, and the one-way air plate is rotatably connected to the top of the rubber plug near the air hole. The bottom of the one-way air plate contacts the output port at the top of the air hole.

[0011] Preferably, a threaded cylinder is welded to the top of the sampling chassis, and the surface of the threaded cylinder is threadedly connected to the bottom of the inner side of the storage tank.

[0012] Preferably, the surface of the storage tank is fitted with an observation window, which is made of tempered glass.

[0013] Preferably, the top of the rear side of the air cylinder is provided with an opening, and a sealing sleeve is adhered to the top of the air cylinder. The sealing sleeve is made of rubber material, and the inner side of the sealing sleeve is in contact with the surface of the piston rod.

[0014] Preferably, a reinforcing sleeve is welded to the top of the rubber stopper, and the inner side of the reinforcing sleeve is engaged with the bottom of the piston rod surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, by setting up a sampling tube, allows the storage tank to form a temporary storage structure for sampled products together with the sampling base and the perforated top plate. The sample can be temporarily stored. The one-way sample delivery structure formed by the one-way cover and the sampling base allows the sample to enter the storage tank through the one-way cover and automatically close. The sampling tube can form a sampling structure for semi-solid and liquid foods together with the sampling needle. By inserting the sampling needle into the semi-solid food, the semi-solid food can be cut into its own inner wall and sent into the storage tank through the sampling tube. Since the perforated top plate and the sampling needle are tubular structures, liquid foods can also be collected, improving the flexibility of collecting semi-solid and liquid foods. 2. This application, by setting up a sampling mechanism, allows the suction component to form a pressure control structure within the storage tank in conjunction with the pressure control component. The pressure adjustment structure, consisting of a handle, piston rod, and rubber stopper, allows the pressure inside the storage tank to become negative as the user pulls the handle to move the piston rod. This negative pressure is achieved when the rubber stopper moves away from the perforated top plate, enabling the collection of food samples. The air path control structure, consisting of an air vent and a one-way air plate, allows air inside the storage tank to enter through the air vent and open the one-way air plate when the rubber stopper approaches the perforated top plate. This discharges excess air from the storage tank, achieving a sealing effect and improving the stability of the storage tank for food sample storage. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A sampling and storage device for food testing includes a sampling cylinder 1 and a sampling mechanism 2, with the sampling mechanism 2 located at the bottom of the sampling cylinder 1. The sampling cylinder 1 includes a storage tank 11, a sampling base 12, a one-way cover 13, a sampling tube 14, a sampling needle tube 15, and a perforated top plate 16. The sampling base 12 is installed at the bottom inside the storage tank 11. The one-way cover 13 is rotatably connected to the output port at the bottom inside the sampling base 12. The sampling tube 14 is connected to the input port at the bottom of the sampling base 12. The sampling needle tube 15 is welded to the bottom of the sampling tube 14. The perforated top plate 16 is welded to the top of the storage tank 11.

[0020] In this embodiment: by setting up the sampling tube 1, the storage tank 11 can form a temporary storage structure for the sampled samples together with the sampling base 12 and the perforated top plate 16. The collected samples can be temporarily stored. The one-way sample delivery structure formed by the one-way cover plate 13 and the sampling base 12 allows the sample to enter the storage tank 11 through the one-way cover plate 13 and automatically close. The sampling tube 14 can form a sampling structure for semi-solid and liquid foods together with the sampling needle tube 15. By inserting the sampling needle tube 15 into the semi-solid food, the semi-solid food can be cut on its own inner wall and sent into the storage tank 11 through the sampling tube 14. Since the perforated top plate 16 and the sampling needle tube 15 are tubular structures, liquid foods can also be collected, which improves the flexibility of collecting semi-solid and liquid foods.

[0021] Specifically, such as Figure 3 As shown, the sampling mechanism 2 includes a suction assembly 21 and a pressure control assembly 22. The suction assembly 21 is located on the top of the perforated top plate 16, and the pressure control assembly 22 is located at the bottom of the suction assembly 21.

[0022] Specifically, such as Figure 4 As shown, the inhalation assembly 21 includes an air pump 211, a piston rod 212, and a handle 213. The air pump 211 is welded to the top of the perforated top plate 16, the piston rod 212 is slidably connected to the top of the inner side of the air pump 211, and the handle 213 is welded to the top of the piston rod 212.

[0023] Specifically, such as Figure 5As shown, the pressure control assembly 22 includes a rubber plug 221, an air hole 222, and a one-way air plate 223. The rubber plug 221 is bolted to the bottom of the piston rod 212. The air hole 222 is opened at the top of the rubber plug 221 and passes through the rubber plug 221. The one-way air plate 223 is rotatably connected to the top of the rubber plug 221 near the air hole 222. The bottom of the one-way air plate 223 contacts the output port at the top of the air hole 222.

[0024] In this embodiment: by setting up the sampling mechanism 2, the suction component 21 can form a structure for controlling the pressure inside the storage tank 11 with the pressure control component 22. Through the pressure adjustment structure composed of the handle 213, piston rod 212 and rubber stopper 221, when the user pulls the handle 213 to move the piston rod 212, the rubber stopper 221 moves with the piston rod 212 in the air cylinder 211. When the rubber stopper 221 moves away from the perforated top plate 16, the pressure inside the storage tank 11 becomes negative pressure, thereby allowing the collection of food samples. Through the air path control structure composed of the air hole 222 and the one-way air plate 223, when the rubber stopper 221 approaches the perforated top plate 16, the air inside the storage tank 11 is allowed to enter through the air hole 222 and open the one-way air plate 223, which can discharge excess air inside the storage tank 11, achieving a sealing effect inside the storage tank 11 and improving the stability of the storage tank 11 when storing food samples.

[0025] Specifically, such as Figure 2 As shown, a threaded cylinder 17 is welded to the top of the sampling chassis 12, and the surface of the threaded cylinder 17 is threadedly connected to the bottom of the inner side of the storage tank 11.

[0026] Specifically, such as Figure 2 As shown, an observation window 18 is snapped onto the surface of the storage tank 11, and the observation window 18 is made of tempered glass.

[0027] In this embodiment: by setting a threaded cylinder 17 and an observation window 18, the threaded cylinder 17 is an auxiliary structure for connecting the sampling base 12 and the storage tank 11. It can increase the stability when connecting the sampling base 12 and the storage tank 11 by utilizing its own threaded structure, thereby improving the stability of temporary storage of food samples. The observation window 18 is a structure that facilitates the user to observe the food samples in the storage tank 11. Through the transparency of its own tempered glass material, the user can directly observe the food storage status in the storage tank 11 through the observation window 18.

[0028] Specifically, such as Figure 4 As shown, the top of the rear side of the air cylinder 211 has an opening, and a sealing sleeve 214 is bonded to the top of the air cylinder 211. The sealing sleeve 214 is made of rubber material, and the inner side of the sealing sleeve 214 is in contact with the surface of the piston rod 212.

[0029] Specifically, such as Figure 5As shown, a reinforcing sleeve 224 is welded to the top of the rubber stopper 221, and the inner side of the reinforcing sleeve 224 is engaged with the bottom of the surface of the piston rod 212.

[0030] In this embodiment: by setting a sealing sleeve 214 and a reinforcing sleeve 224, the sealing sleeve 214 is a sealing structure at the connection between the piston rod 212 and the air cylinder 211, which can seal the gap between the air cylinder 211 and the piston rod 212, and increase the airtightness when the piston rod 212 moves in the air cylinder 211. The reinforcing sleeve 224 is a reinforcing structure at the connection between the rubber stopper 221 and the piston rod 212, which can further increase the stability when the piston rod 212 is connected to the rubber stopper 221 by snapping the piston rod 212.

[0031] Working principle: First, when food samples need to be collected, the user holds the sampling tube 1 and inserts the sampling needle 15 into the food sample. Then, the user holds the handle 213 with the other hand and pulls it upward. The handle 213 will drive the piston rod 212 to move the rubber stopper 221 upward. At this time, the pressure inside the air cylinder 211 will decrease, thus turning into negative pressure. Due to the negative pressure, the sampling needle 15 will transport the food sample upward along the sampling tube 14 to the sampling base 12. Then, the one-way cover 13 will open due to the pushing force of the food, and the food will enter the storage tank 11 for temporary storage. At this time, the one-way cover 13 will automatically close due to the continuous accumulation of food. Then, the user presses the handle 213 down, and the piston rod 212 will push the rubber stopper 221 down. Since the storage tank 11 is already filled with food samples, the air inside will be squeezed into the air hole 222 by the food sample. Then, the one-way air plate 223 will open and enter the air cylinder 211 above the rubber stopper 221, and be discharged from the opening, thus emptying the air in the sampling tube 1. The one-way air plate 223 will automatically close due to the loss of air thrust, and finally the food sample can be collected.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
