Description

Technical Field

[0001] This utility model relates to the field of self-heating pack technology, and in particular to a self-heating pack heat detection device. Background Technology

[0002] In recent years, self-heating foods have become increasingly popular due to their convenience and speed in heating food quickly without the need for an external heat source, leading to a continuously expanding market. Furthermore, as a core component of self-heating foods, the quality and heating performance of the self-heating pack directly impact the quality of the food and the consumer experience. Therefore, during the production of self-heating packs, it is necessary to test their heat output to ensure they meet the required standards.

[0003] The existing testing method involves completely immersing the self-heating pack in a certain amount of water to directly test the water temperature. This method easily overlooks the heat generated by the steam, and the results obtained by this method differ significantly from the actual temperature, which is not conducive to ensuring the accuracy of the test results. Utility Model Content

[0004] In view of this, the present invention aims to provide a self-heating pack heat detection device to help ensure the accuracy of test results.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A self-heating pack heat detection device includes a support, a detection box mounted on the support, a cover plate sealing the top of the detection box, a clamping assembly for clamping the self-heating pack slidably disposed in the detection box, and an exhaust hole opened on the cover plate. The cover plate is provided with a first temperature sensor for detecting the temperature at the exhaust hole. The detection box is provided with a second temperature sensor for detecting the temperature of the water in the detection box. The detection box is provided with a controller, and the first temperature sensor and the second temperature sensor are connected to the controller.

[0007] Furthermore, a sealing element is provided between the cover plate and the detection box, and the detection box and / or the cover plate are provided with grooves for fixing the sealing element.

[0008] Furthermore, the detection box is provided with a placement slot, and a heating chamber is formed between the placement slot and the bottom of the detection box, and the second temperature sensor can detect the temperature of the water in the heating chamber.

[0009] Furthermore, the clamping assembly includes two sliders arranged at intervals in the heating cavity along the width direction of the detection box, and clamping units disposed on each of the sliders, and each clamping unit slides on the inner wall of the heating cavity through the corresponding slider.

[0010] Furthermore, the inner wall of the heating chamber is provided with a first sliding groove adapted to each of the sliders. Each first sliding groove extends along the height direction of the detection box, and each first sliding groove is provided with an electric push rod for driving the corresponding slider to slide.

[0011] Furthermore, each of the clamping units includes two clamping plates arranged at intervals along the height direction of the detection box on the corresponding slider, and an elastic member disposed between the two clamping plates, the elastic member being used to drive the two clamping plates closer together.

[0012] Furthermore, each of the sliders is provided with a second slide groove extending along the height direction of the detection box, and each of the clamps is provided with a protrusion extending into the corresponding second slide groove, and each of the clamps slides in the second slide groove through the corresponding protrusion.

[0013] Furthermore, each of the second slide grooves is provided with a slide post extending along the height direction of the detection box, each clamping plate slides on the corresponding slide post, and each elastic element is sleeved on the corresponding slide post, with both ends of each elastic element connected to the corresponding two protrusions.

[0014] Furthermore, the bottom of the detection box is provided with a recycling component, which is used to recycle the wastewater generated in the heating chamber; the recycling component includes a detachable recycling box located at the bottom of the detection box, a connecting pipe with one end connected to the recycling box and the other end connected to the heating chamber, and a solenoid valve located at one end of the connecting pipe.

[0015] Furthermore, the support is equipped with a water tank, and the water tank is equipped with a metering pump that controls the amount of water delivered to the heating chamber, and the metering pump is connected to the heating chamber through a water supply pipe; and / or, the water tank is equipped with a water volume monitoring window.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] The self-heating pack heat detection device of this utility model, under the action of the clamping component, clamps the self-heating pack and slides it to the bottom of the detection box, and injects water into the detection box. The steam generated by the self-heating pack is detected by the first temperature sensor, and the heat absorbed by the water in the detection box is detected by the second temperature sensor. The test results are transmitted to the controller for collection, thereby improving the accuracy of the test results.

[0018] Secondly, by installing a seal between the cover and the testing chamber, the sealing effect between the cover and the testing chamber can be ensured, preventing heat loss and reducing the error of the test results. A placement slot is set inside the testing chamber, forming a heating cavity between the placement slot and the bottom of the testing chamber. This allows it to simulate the structure of a self-heating food container, thereby simulating heat loss such as heat conduction and convection in an actual self-heating food container. This provides a more realistic simulation of the self-heating pack's heating state, ensuring the accuracy of the test results.

[0019] Furthermore, the clamping assembly consists of a slider and a clamping unit. The slider and clamping unit clamp the self-heating pack and cause it to slide up and down, ensuring stable placement of the pack and preventing scalding to operators when handling it. The first groove guides the slider's movement and provides installation space for the electric push rod, which, under its influence, causes the slider to slide within the corresponding first groove.

[0020] The clamping unit consists of two clamping plates and an elastic element. Driven by the elastic element, the two clamping plates move closer together to clamp the self-heating pack. The structure is simple and easy to design and implement. The second sliding groove and protrusions allow each clamping plate to slide along the second sliding groove via corresponding protrusions, ensuring the stability of the clamping plate sliding. The sliding column restricts the clamping plates, allowing them to slide along the axial direction of the column, preventing the two clamping plates from tilting during sliding. The elastic element is fitted onto the sliding column, with its two ends connected to the two clamping plates respectively, driving the two clamping plates closer together to clamp the self-heating pack.

[0021] Furthermore, by incorporating a recycling component, wastewater in the heating chamber can be recycled, preventing environmental pollution. This component consists of a recycling tank, connecting pipe, and solenoid valve. The recycling tank is detachably located at the bottom of the testing chamber for easy cleaning, improving operational convenience. The water tank, metering pump, and water supply pipe ensure water is supplied to the heating chamber, with the metering pump controlling the consistent water volume each time, reducing variability and resulting in more accurate test results. A water level detection window monitors the remaining water level in the tank, ensuring sufficient water supply. Attached Figure Description

[0039] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Example 1

[0041] This embodiment relates to a self-heating pack heat detection device, which can simultaneously detect the heat of steam and the heat absorbed by water, thus ensuring the accuracy of the test results.

[0042] In terms of overall structure, combined Figures 1 to 5 As shown, the self-heating pack heat detection device of this embodiment includes a support 1, a detection box 2 disposed on the support 1, a cover plate 21 covering the top of the detection box 2, a clamping assembly 3 slidably disposed in the detection box 2 for clamping the self-heating pack, and an exhaust hole 211 opened on the cover plate 21. The cover plate 21 is provided with a first temperature sensor 41 for detecting the temperature at the exhaust hole 211. The detection box 2 is provided with a second temperature sensor 42 for detecting the temperature of the water in the detection box 2. The detection box 2 is provided with a controller 43, and the first temperature sensor 41 and the second temperature sensor 42 are connected to the controller 43.

[0043] At this point, as can be seen from the above, under the action of the clamping component 3, the self-heating pack is clamped and slid to the bottom of the test box 2, and water is injected into the test box 2. The steam generated by the self-heating pack is detected by the first temperature sensor 41, and the heat absorbed by the water in the test box 2 is detected by the second temperature sensor 42. The test results are then transmitted to the controller 43 for collection, thereby improving the accuracy of the test results.

[0044] In practice, the self-heating pack is clamped by the clamping assembly 3 and slid to the bottom of the testing chamber 2. Water is injected into the testing chamber 2, and the cover plate 21 is closed. At this time, the steam generated by the self-heating pack will be discharged from the vent 211. The temperature of the steam is detected by the first temperature sensor 41, and the temperature of the water in the testing chamber 2 is detected by the second temperature sensor 42. The test results are transmitted to the controller 43 for collection. In a specific structure, the first temperature sensor 41 can be inserted into the testing chamber 2 through the vent 211 to avoid heat damage caused by additional openings in the top cover.

[0045] Based on the above overall introduction, in this embodiment, as a preferred implementation, such as Figure 2 and Figure 3 As shown, a sealing element 22 is provided between the cover plate 21 and the test chamber 2, and the test chamber 2 is provided with a groove 23 for fixing the sealing element 22. Here, by providing a sealing element 22 between the cover plate 21 and the test chamber 2, the sealing effect between the cover plate 21 and the test chamber 2 can be guaranteed, heat loss can be avoided, and the error of the test results can be reduced.

[0046] It should be noted that the sealing element 22 in this embodiment can be a sealing product well known to those skilled in the art, such as a sealing strip. In the specific structure, the groove 23 in this embodiment can be set as a dovetail shape. Of course, the shape of the groove 23 can also be designed and adjusted according to the actual situation, as long as the stability of the sealing element 22 can be guaranteed.

[0047] In practice, the sealing element 22 is placed in the groove 23, and the cover plate 21 is placed on top of the test chamber 2. During testing, this prevents heat loss due to poor sealing, which could lead to inaccurate test results. It should be understood that the groove 23 can also be formed on the cover plate 21, or the groove 23 can be formed on both the cover plate 21 and the test chamber 2.

[0048] Furthermore, in order to simulate a real environment, this embodiment, as a preferred implementation, includes... Figure 2 As shown, the detection box 2 is provided with a placement slot 24, and a heating chamber 26 is formed between the placement slot 24 and the bottom of the detection box 2. The second temperature sensor 42 can detect the temperature of the water in the heating chamber 26.

[0049] Here, a placement slot 24 is set inside the test chamber 2, so that a heating cavity 26 is formed between the placement slot 24 and the bottom of the test chamber 2, which can simulate the structure of a self-heating food container, thereby simulating the heat loss such as heat conduction and heat convection in an actual self-heating food container, so as to obtain a more realistic heating state of the self-heating pack and ensure the accuracy of the test results.

[0050] In the specific structure, the inner wall of the testing box 2 is provided with a protrusion 25. The placement slot 24 is placed on the protrusion 25, so that a heating cavity 26 is formed between the placement slot 24 and the bottom of the testing box 2. Food such as rice can be placed in the placement slot 24, thereby simulating the structure of a real self-heating meal box and ensuring the accuracy of the test results. Furthermore, the second temperature sensor 42 is located on the inner wall of the heating cavity 26. After the self-heating pack is submerged in water, the second temperature sensor 42 measures the temperature of the water in the heating cavity 26 and transmits the result to the controller 43.

[0051] In addition, in this embodiment, as a preferred implementation, such as Figure 2 and Figure 4 As shown, the clamping assembly 3 includes two sliders 31 arranged at intervals along the width direction of the detection box 2 in the heating cavity 26, and clamping units 32 provided on each slider 31, and each clamping unit 32 slides on the inner wall of the heating cavity 26 through the corresponding slider 31.

[0052] Understandably, the clamping assembly 3 consists of a slider 31 and a clamping unit 32. The slider 31 and the clamping unit 32 clamp the self-heating pack and drive the self-heating pack to slide up and down, which can ensure the stable placement of the self-heating pack and prevent the operator from being scalded by water when picking up the self-heating pack.

[0053] In the specific structure, two clamping units 32 are arranged opposite to each other. After the two clamping units 32 clamp the self-heating pack, they slide to the bottom of the heating chamber 26 through the corresponding slider 31 and inject water into the heating chamber 26 so that the water overflows the self-heating pack to detect the heat of the self-heating pack.

[0054] Specifically, in this embodiment, as a preferred implementation, such as Figure 4 As shown, the inner wall of the heating chamber 26 is provided with a first slide groove 261 that is adapted to each slider 31. Each first slide groove 261 extends along the height direction of the detection box 2, and each first slide groove 261 is provided with an electric push rod 262 for driving the corresponding slider 31 to slide.

[0055] Here, the first groove 261 provides guidance for the sliding of the slider 31 and also provides installation space for the electric push rod 262. Under the action of the electric push rod 262, the slider 31 slides in the corresponding first groove 261.

[0056] In specific implementation, two first slide grooves 261 are formed on the inner wall of the heating chamber 26, and electric push rods 262 are set in each first slide groove 261. Each slider 31 is set on the driving end of the corresponding electric push rod 262. Under the drive of each electric push rod 262, the corresponding slider 31 slides along the corresponding first slide groove 261.

[0057] Furthermore, in this embodiment, as a preferred implementation, such as Figure 4 and Figure 5 As shown, each clamping unit 32 includes two clamping plates 321 arranged at intervals along the height direction of the detection box 2 on the corresponding slider 31, and an elastic member 322 disposed between the two clamping plates 321. The elastic member 322 is used to drive the two clamping plates 321 closer together.

[0058] Here, the clamping unit 32 consists of two clamping plates 321 and an elastic element 322. Under the drive of the elastic element 322, the two clamping plates 321 can move closer to each other to clamp the self-heating pack. The structure is simple and easy to design and implement.

[0059] In practice, the two clamping plates 321 in each clamping unit 32 are driven to move away from each other, and the side of the self-heating pack is placed between the two clamping plates 321. Under the drive of the elastic member 322, the two clamping plates 321 are brought closer together to clamp the side of the self-heating pack. Subsequently, each electric push rod 262 drives each slider 31 to slide the self-heating pack.

[0060] It should be noted that the elastic element 322 in this embodiment can be an elastic product well known to those skilled in the art, such as a tension spring.

[0061] Furthermore, in this embodiment, as a preferred implementation, such as Figure 5 As shown, each slider 31 is provided with a second slide groove 311 extending along the height direction of the detection box 2, and each clamping plate 321 is provided with a protrusion 3211 extending into the corresponding second slide groove 311. Each clamping plate 321 slides in the second slide groove 311 through the corresponding protrusion 3211.

[0062] Therefore, by setting the second slide groove 311 and the protrusion 3211, each clamping plate 321 can slide along the second slide groove 311 through the corresponding protrusion 3211, ensuring the stability of the sliding of the clamping plate 321. In specific implementation, each clamping plate 321, driven by the corresponding elastic element 322, slides in the corresponding second slide groove 311 through the corresponding protrusion 3211 to clamp the self-heating pack.

[0063] Meanwhile, in this embodiment, as a preferred implementation, it is still as follows: Figure 5 As shown, each of the second slide grooves 311 is provided with a slide post 312 extending along the height direction of the detection box 2. Each clamping plate 321 slides on the corresponding slide post 312, and each elastic element 322 is sleeved on the corresponding slide post 312. The two ends of each elastic element 322 are respectively connected to the two corresponding protrusions 3211.

[0064] Here, the sliding column 312 restricts each clamping plate 321, allowing it to slide along the axial direction of the sliding column 312, preventing the two clamping plates 321 from tilting during sliding. The elastic element 322 is sleeved on the sliding column 312, with its two ends connected to the two clamping plates 321 respectively, driving the two clamping plates 321 closer together to clamp the self-heating pack.

[0065] In practice, each clamping plate 321 is fitted onto the corresponding sliding post 312 via a protrusion 3211, and an elastic element 322 is fitted onto the corresponding sliding post 312, so that the two ends of each elastic element 322 are respectively connected to the bottom of one clamping plate 321 and the top of the other clamping plate 321.

[0066] Furthermore, in this embodiment, as a preferred implementation, such as Figure 1 and Figure 2 As shown, the bottom of the detection box 2 is equipped with a recycling component 5, which is used to recycle the wastewater generated in the heating chamber 26. Here, by setting up the recycling component 5, the wastewater in the heating chamber 26 can be recycled, preventing it from polluting the environment.

[0067] The recycling assembly 5 includes a detachable recycling box 51 located at the bottom of the detection box 2, a connecting pipe 52 with one end connected to the recycling box 51 and the other end connected to the heating chamber 26, and a solenoid valve 53 located at one end of the connecting pipe 52. The advantage of this arrangement is that the recycling assembly consists of the recycling box 51, the connecting pipe 52, and the solenoid valve 53. The detachable location of the recycling box 51 at the bottom of the detection box 2 facilitates cleaning of the recycling box 51 and improves operational convenience.

[0068] It should be noted that the recycling bin 51 and the detection bin 2 in this embodiment can be connected by screws. Of course, in addition to screws, other common detachable connection methods, such as snap-fit, can also be used.

[0069] In practice, when water is injected into the heating chamber 26, the solenoid valve 53 is in the closed state. After the self-heating pack finishes heating, the water in the heating chamber 26 will contain impurities. At this time, the solenoid valve 53 is opened, and the water in the heating chamber 26 will flow into the recycling tank 51 through the connecting pipe 52 for centralized recycling. After collection, the recycling tank 51 is removed, and the collected wastewater is treated to prevent it from polluting the environment.

[0070] In addition, in this embodiment, as a preferred implementation, such as Figure 2 As shown, a water tank 6 is provided on the bracket 1, and a metering pump 61 is provided in the water tank 6 to control the amount of water delivered to the heating chamber 26. The metering pump 61 is connected to the heating chamber 26 through a water supply pipe 62.

[0071] By setting up the water tank 6, the metering pump 61 and the water supply pipe 62, water can be delivered into the heating chamber 26, and the metering pump 61 controls the water delivery volume to be the same each time, reducing variables and making the test results more accurate.

[0072] Furthermore, the water tank 6 is equipped with a water level monitoring window 63. The advantage of this design is that the remaining water level in the water tank 6 can be monitored through the water level monitoring window to ensure that the water tank 6 has sufficient water.

[0073] In practice, after each clamping unit 32 clamps the self-heating pack and drives it to slide to the bottom of the heating chamber 26, water is injected into the heating chamber 26 through the metering pump 61 and the water supply pipe 62 until it overflows the self-heating pack, and then the supply is stopped.

[0074] In this embodiment, the self-heating pack heat detection device clamps the self-heating pack under the action of the clamping plates 321 and elastic members 322 in each clamping unit 32. The slider 31 is pushed by each electric push rod 262, causing the self-heating pack to slide to the bottom of the heating chamber 26. Next, water is supplied to the heating chamber 26 through the metering pump 61 and water pipe 62. After the water has overflowed the self-heating pack, the placement slot 24 is placed in the detection box 2, and the cover plate 21 is closed. The heat of the generated steam is detected by the first temperature sensor 41, and the water in the heating chamber 26 is detected by the second temperature sensor 42. The detection results are transmitted to the controller 43 for collection, allowing the experimenter to obtain the heat data of the self-heating pack more intuitively.

[0075] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
