Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically a testing device for detecting temperature and humidity in the inner packaging of food. Background Technology

[0002] Food packaging temperature and humidity detection devices are used to measure and monitor temperature and humidity changes within food packaging. They work by using built-in sensors to measure and record temperature and humidity data. These sensors detect changes in temperature and humidity within the packaging and convert them into electrical signals for transmission and processing. For on-site food inspection, handheld thermometers and hygrometers are typically used.

[0003] Currently, to prevent probe damage, handheld thermometers and hygrometers use a breathable protective cover to protect the probe. However, when testing granular or small food items, the food can easily pass through or block the vents, reducing the breathability of the protective cover and leading to inaccurate test results. Furthermore, the protective cover needs to be manually cleaned after it becomes clogged before testing can continue, which seriously affects the efficiency of temperature and humidity testing of food packaging.

[0004] Therefore, it is necessary to provide a detection device for detecting temperature and humidity in the inner packaging of food to solve the problems mentioned in the background art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detection device for detecting temperature and humidity in food inner packaging, comprising a base, a fixed head, a probe, a protective mechanism, a display screen, and a handle, wherein the fixed head is fixedly mounted on the base, the output end of the fixed head is provided with a probe and a protective mechanism for protecting the probe, the top of the base is fixedly mounted with a display screen, and the bottom of the base is fixedly mounted with a handle.

[0006] Furthermore, as a preferred embodiment, the protective mechanism includes an outer protective cover and an inner protective cover, wherein the outer protective cover is fixedly mounted on the fixed head, the inner protective cover is rotatably mounted on the fixed head, and the inner protective cover and the outer protective cover are rotatably sleeved together.

[0007] Furthermore, as a preferred embodiment, the protective cover has a plurality of through holes evenly spaced around its circumference;

[0008] The inner protective cover has multiple through holes 2 evenly distributed around its circumference. Multiple spacers are fixedly arranged around the inner protective cover. The spacers are located in the middle of the through holes 2. The other end of the spacers is attached to the inner wall of the outer protective cover. The through hole 1 is located between two adjacent spacers.

[0009] Furthermore, as a preferred embodiment, a discharge hole is provided between the protective cover and the fixing head.

[0010] Furthermore, as a preferred embodiment, the protective inner cover has multiple vent slits evenly spaced around its circumference, and the positions of the vent slits correspond to the positions of the second through hole.

[0011] Furthermore, as a preferred embodiment, the protective inner cover is symmetrically fixed with support rods at one end near the fixed head, and an adjustment ring is fixedly mounted on the support rods;

[0012] The fixed head is symmetrically provided with deflection grooves, and the two support rods slide along the two deflection grooves respectively. The deflection range of the deflection grooves is 175°. The adjusting ring is attached to the outer surface of the fixed head and rotates along the outer surface of the fixed head.

[0013] Furthermore, preferably, the diameter of the first through hole is larger than the diameter of the second through hole.

[0014] Compared with the prior art, this utility model provides a detection device for detecting temperature and humidity in the inner packaging of food, which has the following beneficial effects:

[0015] In this invention, the protective mechanism is configured as a double-layer structure consisting of an inner protective cover and an outer protective cover. This allows food particles entering through the through-hole on the outer protective cover to be isolated in the interlayer space between the inner and outer protective covers. Subsequently, the rotation of the inner protective cover and the spacer plate fixedly installed on the inner protective cover can effectively discharge the food particles from the through-hole and discharge hole at the bottom of the outer protective cover. This prevents food from clogging the protective mechanism and causing air circulation problems, thereby effectively improving the accuracy and efficiency of the detection results.

[0022] Please see Figures 1-5 In this embodiment of the present invention, a detection device for detecting temperature and humidity in food inner packaging includes a base 1, a fixing head 2, a probe head 3, a protective mechanism 4, a display screen 5, and a handle 6. The fixing head 2 is fixedly mounted on the base 1, and the output end of the fixing head 2 is provided with a probe head 3 and a protective mechanism 4 for protecting the probe head 3. The display screen 5 is fixedly mounted on the top of the base 1, and the handle 6 is fixedly mounted on the bottom of the base 1.

[0023] The protective mechanism 4 includes an outer protective cover 41 and an inner protective cover 42. The outer protective cover 41 is fixedly mounted on the fixed head 2, and the inner protective cover 42 is rotatably mounted on the fixed head 2. The inner protective cover 42 and the outer protective cover 41 are rotatably sleeved together.

[0024] The protective outer cover 41 has multiple through holes 411 evenly distributed around its circumference;

[0025] The inner protective cover 42 is provided with a plurality of through holes 421 evenly distributed around its circumference. A plurality of spacers 422 are fixedly arranged around its circumference. The spacers 422 are located in the middle of the through holes 421. The other end of the spacers 422 is attached to the inner wall of the outer protective cover 41. The through hole 411 is located between two adjacent spacers 422.

[0026] A discharge hole 412 is provided between the protective cover 41 and the fixing head 2;

[0027] The protective inner cover 42 has a plurality of ventilation slits 423 evenly distributed around its circumference, and the positions of the ventilation slits 423 correspond to the positions of the through holes 421.

[0028] Specifically, the spacer plate 422 is positioned in the middle of the second through hole 421 so that the spacer plate 422 can separate the second through hole 421, thereby reducing its aperture size and preventing granular food from passing through the second through hole 421. In addition, the ventilation seam 423 can further improve the ventilation of the protective inner cover 42 and ensure the accuracy of the test results.

[0029] The protective inner cover 42 is symmetrically fixed with support rods 424 at one end near the fixed head 2, and an adjustment ring 425 is fixedly installed on the support rods 424;

[0030] The fixed head 2 is symmetrically provided with deflection grooves 21, and the two support rods 424 slide along the two deflection grooves 21 respectively. The deflection range of the deflection grooves 21 is 175°. The adjusting ring 425 is attached to the outer surface of the fixed head 2 and rotates along the outer surface of the fixed head 2.

[0031] It should be noted that the deflection range of the deflection groove 21 is 175°. This arrangement allows the support rod 424 to deflect at an angle of 175° in the deflection groove 21. That is, the inner protective cover 42 can rotate 175° along the outer protective cover 41, thereby ensuring that the partition plate 422 at the top of the inner protective cover 42 can rotate the bottom of the inner protective cover 42, thus effectively conveying the food that enters from the through hole 411 out through the through hole 411 and the arrangement hole 412 at the bottom of the outer protective cover 41.

[0032] The diameter of the first through hole 411 is larger than the diameter of the second through hole 421.

[0033] During implementation, the probe 3 is inserted into the inner packaging of the food for temperature and humidity detection. During this process, the protective mechanism 4 enters the inner packaging along with the probe. Air in the inner packaging is then detected by the probe 3 through vent 411 and through-hole 421, thus detecting the temperature and humidity within the packaging. Simultaneously, if granular or other small food items are present in the inner packaging, they enter through through-hole 411 and are then isolated in the space between the outer protective cover 41 and the inner protective cover 42 by the partition plate 422. Rotating the adjusting ring 425 causes the inner protective cover 42 to rotate, causing the partition plate 422 to rotate along with it and push the granular food items to rotate. This allows the granular food items to exit through through-hole 411 and discharge hole 412 at the bottom of the outer protective cover 41, ensuring that the air permeability of through-hole 411 and through-hole 421 is not affected, effectively preventing food from clogging the protective mechanism 4 and improving the accuracy of the detection results.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
