Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a sampling device for fluid food detection. Background Technique

[0002] Due to the wide variety and complex composition of foods, the attention to food safety is also increasing. In order to ensure the safety of food quality, all foods of different varieties in the same batch will be monitored to ensure the quality and safety of food. During the detection of fluid food, a sampling device will be used. Sampling is the process of extracting samples from the population, and then the process of conducting tests or observations on the population, using the sample to reflect the quality of the population.

[0003] For example, a sampling device for fluid food detection with the publication number CN214621861U, which relates to the technical field of food detection, includes a cylinder body, and a side plate is installed on one side of the cylinder body. In the utility model, by setting a baffle, a groove, a discharge port, a second spring, a sleeve and a movable rod, through the threaded connection between the sampling bottle and the cylinder body, when the sampling bottle rotates at the discharge port, the movable rod is driven to push the baffle upwards, and at the same time, the second spring is driven to stretch, so that the baffle opens the discharge port, and then the first push rod is pushed to squeeze the extracted fluid food into the sampling bottle. When it is necessary to replace the sampling bottle after the fluid food collected by the sampling bottle meets the requirements, the sampling bottle can be rotated, so that the second spring generates a contracting force after being stretched, which drives the baffle and the sleeve to move downwards, so that the baffle closes the discharge port, effectively avoiding the outflow of fluid food.

[0004] To sum up, it can be seen that the following technical problems exist in the prior art: when the existing device samples the fluid, one hand needs to hold the cylinder body, and then the other hand needs to pull the pull rod to drive the piston to generate negative pressure inside the cylinder body to suck the fluid, so as to sample the fluid food detection. Two hands need to be operated simultaneously, which is inconvenient to use. Therefore, we design a sampling device for fluid food detection to provide another technical solution for the above technical problems. Content of the Utility Model

[0005] Based on this, it is necessary to provide a fluid food detection sampling device for the above-mentioned technical problems. By pressing the push handle, the push rod and the piston are driven to move downward, and the first spring is compressed by the button. The push rod is limited by the limiting mechanism to prevent the piston from rebounding. During sampling, the staff inserts the sampling tube into the fluid, then presses the button, operates the limiting mechanism to release the limit on the push rod, and drives the piston to move upward through the elastic action of the first spring, so that a negative pressure is generated inside the cylinder body, and the sample is thus sucked into the sampling bottle body through the sampling tube, enabling the staff to operate with one hand during sampling, which is beneficial to improving the convenience of using the device.

[0027] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other

[0028] Please refer to Figures 1-6 ,

[0029] It includes a cylinder body 1 and a sampling bottle body 3. The sampling bottle body 3 is made of transparent plastic. A housing 2 is fixed at the bottom of the cylinder body 1. One end of the sampling bottle body 3 is fixed with a sampling bottle mouth 24, and the sampling bottle mouth 24 is used to be inserted on one side of the housing 2. A material taking pipe 4 is fixed at the bottom of the housing 2. A push rod 7 is slidably connected inside the cylinder body 1. A push handle 6 is arranged at the top of the cylinder body 1, and the push handle 6 is fixed at one end of a U-shaped frame 17. The other end of the push rod 7 is fixed with a piston 15, and the piston 15 is slidably connected inside the cylinder body 1. A first spring 16 is arranged on the side of the piston 15 away from the push rod 7, and the first spring 16 is located at the bottom inside the cylinder body 1. A button 5 is arranged on one side of the cylinder body 1, and a limiting mechanism is arranged at the top inside the cylinder body 1. Before sampling, the staff presses the push handle 6 to drive the push rod 7 and the piston 15 to move downward, and compresses the first spring 16 through the button 5, and limits the push rod 7 through the limiting mechanism to prevent the piston 15 from rebounding. When sampling, the staff inserts the material taking pipe 4 into the fluid, then presses the button 5, operates the limiting mechanism to release the limit on the push rod 7, and drives the piston 15 to move upward through the elastic action of the first spring 16, so that negative pressure is generated inside the cylinder body 1, and thus the sample is sucked into the sampling bottle body 3 through the material taking pipe 4, enabling the staff to operate with one hand during sampling, which is beneficial to improving the convenience of using the device;

[0030] The limiting mechanism includes an avoidance groove 14 opened inside the push rod 7. A clamping groove 20 is opened at the top of the push rod 7 and inside the avoidance groove 14. A clamping plate 19 is slidably connected inside the cylinder body 1, and the clamping plate 19 is located inside the avoidance groove 14. Two guide rods 13 are symmetrically fixed inside the cylinder body 1, and the two guide rods 13 are respectively slidably connected with both ends of the clamping plate 19. The guide rods 13 are used to guide and limit the clamping plate 19. A second spring 18 is arranged on one side of the clamping plate 19 and on the surface of the guide rod 13. A U-shaped frame 17 is fixed on the other side of the clamping plate 19. A transmission rod 12 is fixed at the side of the U-shaped frame 17 away from the clamping plate 19. The end of the transmission rod 12 away from the U-shaped frame 17 is fixed with the button 5, and the transmission rod 12 is slidably connected with the cylinder body 1. Specifically, when the staff presses the push handle 6, the push rod 7 moves downward. When the clamping groove 20 moves to the position of the clamping plate 19, the clamping plate 19 is driven by the second spring 18 to be clamped into the inside of the clamping groove 20, thereby limiting the push rod 7. The staff presses the button 5 to drive the transmission rod 12, the U-shaped frame 17 and the clamping plate 19 to move in a direction away from the button 5, so that the clamping plate 19 is disengaged from the inside of the clamping groove 20, thereby releasing the limit on the push rod 7;

[0031] A ventilation hole 23 is opened at the top of the cylinder body 1, and the ventilation hole 23 is used to balance the air pressure inside the cylinder body 1;

[0032] Inside the housing 2, a fixed partition 11 is fixedly installed. At the bottom of the cylinder 1 and inside the housing 2, an air suction pipe 10 is fixedly installed. Both the air suction pipe 10 and the material taking pipe 4 penetrate through the fixed partition 11 and are fixed to the fixed partition 11. One end of the air suction pipe 10 is located inside the housing 2, and one end of the material taking pipe 4 extends out of the housing 2. At one end of the sampling bottle mouth 24, jacks 9 are symmetrically fixedly installed. One ends of the material taking pipe 4 and the air suction pipe 10 are respectively inserted into the inside of the sampling bottle body 3 through the jacks 9. Specifically, the fixed partition 11 is used to fix the air suction pipe 10 and the material taking pipe 4. When negative pressure is generated inside the cylinder 1, the inside of the sampling bottle body 3 is sucked through the air suction pipe 10 to generate negative pressure inside the sampling bottle body 3, so that the fluid food is sucked into the inside of the sampling bottle body 3 through the material taking pipe 4. The fluid sample inside the sampling bottle body 3 should avoid submerging one end of the air suction pipe 10;

[0033] On one side of the sampling bottle mouth 24, an anti-fooling groove 21 is provided. Inside the housing 2, an anti-fooling protrusion 22 is fixedly installed. The anti-fooling protrusion 22 is used to be inserted into the anti-fooling groove 21. When inserting the sampling bottle mouth 24 into the inside of the housing 2, by aligning the anti-fooling groove 21 with the anti-fooling protrusion 22, the positions of the material taking pipe 4 and the air suction pipe 10 and the jack 9 are aligned, so that the material taking pipe 4 and the air suction pipe 10 can accurately be inserted into the inside of the sampling bottle body 3 through the jacks 9;

[0034] Inside the jack 9, a valve 8 is fixedly installed. The valve 8 is made of rubber. When the air suction pipe 10 and the material taking pipe 4 are pulled out of the jack 9, the valve 8 can scrape the fluid food adhered to the surfaces of the air suction pipe 10 and the material taking pipe 4, and close the channel of the jack 9 in time after the air suction pipe 10 and the material taking pipe 4 are pulled out, preventing the liquid inside the sampling bottle body 3 from spilling out or being contaminated, and improving the use effect of the device.

[0035] The use process of a fluid food detection sampling device provided by the present utility model is as follows:

[0036] Technical principle: The staff presses the push handle 6, causing the push rod 7 to move downward. When the clamping groove 20 moves to the position of the clamping plate 19, the second spring 18 drives the clamping plate 19 to be clamped into the inside of the clamping groove 20, thereby limiting the push rod 7 and preventing the piston 15 from rebounding. During sampling, the staff inserts the material taking pipe 4 into the fluid, and then presses the button 5, driving the transmission rod 12, U-shaped frame 17 and clamping plate 19 to move away from the button 5, causing the clamping plate 19 to disengage from the inside of the clamping groove 20, thus releasing the limit on the push rod 7. The elastic action of the first spring 16 drives the piston 15 to move upward, generating negative pressure inside the cylinder body 1. The inside of the sampling bottle body 3 is sucked through the air suction pipe 10, generating negative pressure inside the sampling bottle body 3. Thus, the fluid food is sucked into the sampling bottle body 3 through the material taking pipe 4, enabling the staff to operate with one hand during sampling, which is beneficial to improving the convenience of using the device.
