[0003] For example, when a transport box is used in the takeout industry, it needs to have the functions of insulation, refrigeration and heating. However, traditional takeout boxes generally achieve insulation through simple insulation paper and cannot achieve true refrigeration and heating, which affects the taste of the food and even causes food to spoil.

In order to ensure the accuracy of the test results, many requirements are put forward for transportation.

[0052] Example 1

[0053] This embodiment provides a temperature adjustment device, such as Figure 1-18 As shown, the temperature regulating device includes a magnetic field component 1, a magnetic regenerative body component 2, a driving component 3 and a temperature extraction component 5. The magnetic regenerative body component 2 is filled with gadolinium element 4. One end of the magnetic regenerative body component 2 is located in the magnetic field component 1. The driving component 3 is connected to the magnetic regenerative body component 2 for driving the magnetic regenerative body component 2 to rotate, so that the end of the magnetic regenerative body component 2 located in the magnetic field component 1 forms a hot end 21, and the end located outside the magnetic field component 1 forms a cold end 22; the temperature extraction component 5 has a first static end and a first dynamic end connected to the hot end 21, and a second static end and a second dynamic end connected to the cold end 22. The first dynamic end rotates with the magnetic regenerative body component 2 and can be connected to the first static end or the second static end. The second dynamic end rotates with the magnetic regenerative body component 2 and can be connected to the second static end or the first static end.

[0054] The molecular formula of gadolinium is Gd. It is a rare earth element and also a magnetic material. As a magnetic material, gadolinium has a magnetocaloric effect. The magnetocaloric effect refers to the phenomenon that the magnetization and demagnetization of gadolinium are accompanied by temperature changes. Specifically, when gadolinium is magnetized in a magnetic field, its internal magnetic moment becomes ordered, such as Figure 2 As shown, the magnetic entropy of the material decreases and heat is released to the outside. On the contrary, when the magnetic field is removed and the gadolinium element is demagnetized, the magnetic moment becomes disordered, as shown in Figure 1As shown, the magnetic entropy increases and the gadolinium element absorbs heat from the outside, thus achieving a cooling effect.

[0055] In this embodiment, the magnetic field component 1 can be a permanent magnet, which is used to provide excitation and form a magnetic field environment; the magnetic regenerator component 2 is used to place the gadolinium element 4, which is in granular form and can be wrapped by a high and low temperature resistant packaging material and placed in the magnetic regenerator component 2; the driving component 3 is used to drive the magnetic regenerator component 2 to rotate.

[0056] For better explanation, it is assumed that the magnetic regenerative body component 2 includes a first part and a second part. In the initial state, the first part is located in the magnetic field formed by the magnetic field component 1, and the second part is located outside the magnetic field. Then in the specific implementation process, the driving component 3 drives the magnetic regenerative body component 2 to rotate. At a certain moment, the second part is located in the magnetic field, and the first part is located outside the magnetic field. Because the first part and the second part have gadolinium elements 4, when the second part enters the magnetic field, the gadolinium elements set in the second part will release heat to the outside world, so that the second part forms a hot end 21, and when the first part leaves the magnetic field, the gadolinium elements 4 set in the first part will absorb heat from the outside world, so that the first part forms a cold end 22. After that, the driving component 3 continues to work. At a certain moment, the second part is located outside the magnetic field and the first part is located in the magnetic field. At this time, the second part is the cold end 22 and the first part is the hot end 21. In this way, under the action of the driving component 3, the first part and the second part repeatedly enter and exit the magnetic field respectively, ensuring that the cold end 22 and the hot end 21 always exist.

[0057] From the above description, it can be seen that the hot end at different times corresponds to different parts of the magnetic heat recovery body assembly 2, but no matter how it changes, the hot end 21 is always the end located inside the magnetic field assembly 1, and the cold end 22 is always the end located outside the magnetic field assembly 1. In other words, the relative positions of the hot end 21 and the cold end 22 are fixed. In the specific use process, the cold end 22 can be corresponding to a certain space to adjust the temperature in the space, and the hot end 21 can be corresponding to another space to adjust the temperature of the space.

[0058] This embodiment cleverly utilizes the magnetocaloric effect of gadolinium element 4, which can heat and cool a specific space. After applying it in a transport box, it can transport items with specific needs, solving the technical problem that traditional transport boxes cannot be refrigerated or heated, and thus the transported items cannot meet the requirements.

[0059] In addition, in order to dissipate cold and heat into the required space, the temperature regulating device provided in this embodiment also includes a temperature extraction component 5, which has a first static end and a first dynamic end connected to the hot end 21 and a second static end and a second dynamic end connected to the cold end 22. That is to say, in one state, the first static end and the first dynamic end are connected to realize the transfer of cold, and the second static end and the second dynamic end are connected to realize the transfer of heat; and as the magnetic heat recovery body component 2 rotates, the first dynamic end and the second dynamic end follow the rotation. At this time, in another state, the first dynamic end is connected to the second static end, and the second dynamic end is connected to the first static end. This setting method avoids the rotation of the magnetic heat recovery body component 2 causing the heat and cold to be unable to be transferred.

[0060] In a specific embodiment, Figure 3 As shown, the driving assembly 3 includes a driving member 31 and a transmission unit 32 , the output end of the driving member 31 is connected to one end of the transmission unit 32 , and the other end of the transmission unit 32 is connected to the magnetic heat recovery body assembly 2 .

[0061] Specifically, in order to realize the rotation of the magnetic heat recovery body component 2, an external force needs to be applied to it. Since the magnetic heat recovery body component 2 is dynamic, it is difficult to drive it directly through the driving member 31, so a transmission unit 32 is added to transmit the driving force. The traditional driving member is generally a motor, but in this embodiment, considering the application of the temperature adjustment device, since the motor has a large noise, it is excluded to provide the driving force through the motor.

[0062] In a specific embodiment, Figure 3 As shown, Figure 6 as well as Figure 7 As shown, the driving member 31 is a quartz crystal oscillator 311, and one end of the quartz crystal oscillator 311 has a first S pole 312 and a first N pole 313; the transmission unit 32 includes a gear 321, one end of the gear 321 is meshed with the magnetic heat recovery body component 2, and the other end of the gear 321 has a second S pole 322 and a second N pole 323, and the second S pole 322 and the second N pole 323 are located in the space formed by the first S pole 312 and the first N pole 313;

[0063] The quartz crystal oscillator 311 can change the relative positions of the first S pole 312 and the first N pole 313 to drive the gear 321 to rotate through the repulsion of like poles with the second S pole 322 and the second N pole 323, thereby driving the magnetic heat recovery body assembly 2 to rotate.

[0064] The magnetic heat recovery body component 2 is a circular structure, with a protruding hollow columnar structure in the middle. The inner surface of the columnar structure has a toothed structure 23, and the toothed structure 23 meshes with the gear 321 to achieve the transmission of driving force.

[0065] The quartz crystal oscillator 311, also known as a quartz resonator, is made of a quartz crystal with a piezoelectric effect. This quartz crystal sheet will generate mechanical vibrations under the action of an external alternating electric field. Specifically, the voltage effect phenomenon is generated by the extension and contraction of the quartz tuning fork in the quartz transistor. When a voltage is applied to the tuning fork, the tuning fork extends and bends. In the opposite direction, the voltage is interrupted and the tuning fork returns to its original state. The back-and-forth deformation generates positive and negative voltages, which can create a vibration mode. Through the integrated circuit of the inverter on the micro-circuit board, a feedback circuit is formed with two capacitors to assist the voltage from the inverter and the feedback circuit to be timed, thereby generating a resonant motion in the crystal. After a series of controls, the oscillation frequency of the quartz crystal tuning fork reaches the required value, and then this signal will be sent to the controller of the electromagnet, which will have the direction of the magnetic field reversal of the electromagnet, that is, the above-mentioned quartz crystal oscillator 311 can change the relative position of the first S pole 312 and the first N pole 313.

[0066] During operation, when the magnetism of the first S pole 312 and the first N pole 313 and the second S pole 322 and the second N pole 323 at the corresponding positions is the same, due to the repulsion of like poles, the second S pole 322 and the second N pole 323 need to change positions. At this time, the second S pole 322 and the second N pole 323 will drive the gear 321 to rotate until the magnetism of the first S pole 312 and the first N pole 313 and the second S pole 322 and the second N pole 323 at the corresponding positions are opposite; then the quartz crystal oscillator 311 changes the position of the first N pole 313 and the second S pole 322. At this time, the magnetism of the first S pole 312 and the first N pole 313 and the second S pole 322 and the second N pole 323 at the corresponding positions are the same again, and the gear 321 continues to rotate.

[0067] Compared with the traditional motor, the quartz crystal oscillator 311 used in this embodiment has the advantages of stable vibration and low power consumption, and it can easily achieve the 180° rotation requirement of the magnetic heat recovery body component 2.

[0068] In a specific embodiment, Figure 8 As shown, the temperature regulating device also includes a temperature extraction component 5, and the temperature extraction component 5 includes a heat extraction unit 51 and a cold extraction unit 52, one end of the heat extraction unit 51 is connected to the hot end 21, and the other end of the heat extraction unit 51 is used to dissipate heat to the first space, one end of the cold extraction unit 52 is connected to the cold end 22, and the other end of the cold extraction unit 52 is used to absorb heat from the second space.

[0069] The heat extraction unit 51 in the temperature extraction component 5 is mainly used to dissipate the heat generated by the hot end 21 to the first space, so that the first space has a heating function; the cold extraction unit 52 is mainly used to absorb the heat in the second space through the cold generated by the cold end 22, so that the second space has the function of refrigerating items.

[0070] In a specific embodiment, Figure 9-12 As shown, the heat extraction unit 51 includes a first inlet pipe 511, a first outlet pipe 512, a hot end pump body 513 and a radiator 514. The hot end pump body 513 is located on the first inlet pipe 511 or the first outlet pipe 512. One end of the first inlet pipe 511 is used for heat exchange medium to enter. The other end of the first inlet pipe 511 is connected to the hot end 21 and connected to one end of the first outlet pipe 512. The other end of the first outlet pipe 512 is connected to the first space through the radiator 514. The heat exchange medium is water or refrigerant.

[0071] The heat extraction unit 51 mainly takes out the heat through the heat exchange medium and then dissipates it into the first space, thereby heating the first space. Specifically, a portion of the first inlet pipe 511 and the first outlet pipe 512 are both inserted into the gadolinium element 4 of the magnetic regenerative body component 2; the heat exchange medium enters from one end of the first inlet pipe 511 and then flows to the other end. Since the other end is located in the hot end 21, the heat exchange medium absorbs heat at this time and flows into one end of the first outlet pipe 512 in the gadolinium element 4 of the magnetic regenerative body component 2, and flows into the radiator 514 through the other end of the first outlet pipe 512, and then the heat exchange medium with heat dissipates the heat into the first space through the radiator 514.

[0072] In addition, in this embodiment, the hot end pump body 513 can be arranged on the first inlet pipe 511 or the first outlet pipe 512, and is mainly used to drive the flow of the heat exchange medium.

[0073] In a specific embodiment, the cold extraction unit 52 includes a second inlet pipe 521, a second outlet pipe 522, a cold end pump body 523 and a heat exchanger 524. The cold end pump body 523 is located on the second inlet pipe 521 or the second outlet pipe 522. One end of the second inlet pipe 521 is used for heat exchange medium to enter. The other end of the second inlet pipe 521 is connected to the cold end 22 and connected to one end of the second outlet pipe 522. The other end of the second outlet pipe 522 is connected to the second space through the heat exchanger 524. The heat exchange medium is water or a refrigerant.

[0074] The cold extraction unit 52 mainly absorbs the heat in the second space through the heat exchange medium to achieve cooling of the second space. Specifically, the second inlet pipe 521 and the second outlet pipe 522 are partially inserted into the gadolinium element 4 of the magnetic regenerative body component 2; the heat exchange medium enters from one end of the second inlet pipe 521 and then flows to the other end. Since the other end is located in the cold end 22, the heat exchange medium releases heat at this time and flows into one end of the second outlet pipe 522 in the gadolinium element 4 of the magnetic regenerative body component 2, and is connected to the heat exchanger 524 through the other end of the second outlet pipe 522, and then absorbs the heat of the second space through the heat exchanger 524.

[0075] In addition, in this embodiment, the cold-end pump body 523 can be arranged on the second inlet pipe 521 or the second outlet pipe 522, and is mainly used to drive the flow of the heat exchange medium.

[0076] In a specific embodiment, the first inlet pipe 511 and the first outlet pipe 512 both include the first static end and the first dynamic end connected to each other, at least a portion of the first dynamic end is inserted into the magnetic heat recovery body component 2, and it can rotate with the magnetic heat recovery body component 2; the second inlet pipe 521 and the second outlet pipe 522 both include the second static end and the second dynamic end connected to each other, at least a portion of the second dynamic end is inserted into the magnetic heat recovery body component 2, and it can rotate with the magnetic heat recovery body component 2; when the first dynamic end rotates to the outside of the magnetic heat recovery body component 2, it can be connected to the second static end; when the second dynamic end rotates to the inside of the magnetic heat recovery body component 2, it can be connected to the first static end.

[0077] Since the magnetic heat recovery body component 2 is dynamic, in order to achieve the coordination between the cold extraction unit 52 and the magnetic heat recovery body component 2, the first inlet pipe 511 and the first outlet pipe 512 must have a static end and a dynamic end, namely the above-mentioned first static end and first dynamic end, and at the same time, the second inlet pipe 521 and the second outlet pipe 522 must also have a static end and a dynamic end, namely the above-mentioned second static end and second dynamic end.

[0078] For better explanation, assuming that the first dynamic end is located in the magnetic regenerative body component 2 in the magnetic field component 1 in the current state, the first dynamic end is connected to the first static end for heat transfer, and the second static end and the second dynamic end are used to transfer cold. When the magnetic regenerative body component 2 rotates 180°, the first dynamic end and the second dynamic end swap positions, and the second dynamic end is located in the magnetic regenerative body component 2 in the magnetic field component 1, while the first static end and the second static end maintain their original positions. At this time, the second dynamic end is located in the magnetic regenerative body component 2 in the magnetic field component 1, and the second dynamic end is connected to the first static end for heat transfer, while the first dynamic end is connected to the second static end for cold transfer.

[0079] That is to say, this embodiment divides each pipeline into a dynamic end and a static end, so that after the magnetic regenerative body component 2 rotates 180 degrees, the pipeline (dynamic end) inside the magnetic regenerative body component 2 can still be connected to the corresponding pipeline (static end). Of course, in order to achieve this function, the first inlet pipe 511 and the second inlet pipe 521 should be symmetrically arranged about the center of the magnetic regenerative body component 2, and the first outflow pipe 512 and the second outflow pipe 522 should also be symmetrically arranged about the center of the magnetic regenerative body component 2.

[0080] In a specific embodiment, Figure 8 and Fig.11 As shown, the temperature extraction component 5 also includes a distribution valve 53, which is arranged on the magnetic heat recovery body component 2 and is located between the first static end and the first dynamic end, and between the second static end and the second dynamic end; the distribution valve 53 is provided with a hot end connection hole 531 and a cold end connection hole 532, as shown in FIG. Fig.13 As shown, the hot end connecting hole 531 is used to connect the first static end and the first dynamic end or the second dynamic end located inside the magnetic heat recovery body component 2, and the cold end connecting hole 532 is used to connect the second static end and the second dynamic end or the first dynamic end located outside the magnetic heat recovery body component 2.

[0081] In order to avoid excessive leakage of heat exchange medium during the docking of the static end and the dynamic end, a distribution valve 53 is provided in this embodiment. During the rotation of the magnetic heat recovery body assembly 2, the distribution valve 53 is fixed. The hot end connection hole 531 and the cold end connection hole 532 on the distribution valve 53 penetrate the thickness of the distribution valve 53. The end of the first static end close to the distribution valve 53 is inserted into the hot end connection hole 531, and the end of the second static end close to the distribution valve 53 is inserted into the cold end connection hole 532, while the ends of the first dynamic end and the second dynamic end are as close to the distribution valve 53 as possible, and are located directly below the hot end connection hole 531 and the cold end connection hole 532 of the distribution valve 53, so as to achieve docking with the corresponding static end.

[0082] In a specific embodiment, a plurality of first dynamic ends of the first inlet pipe 511 and a plurality of second dynamic ends of the second inlet pipe 521 are provided, and the inlets of the plurality of first dynamic ends are connected to the corresponding first static ends after being collected together, and the inlets of the plurality of second dynamic ends are connected to the corresponding second static ends after being collected together.

[0083] The first dynamic end of the first inlet pipe 511 and the second dynamic end of the second inlet pipe 521 are both provided in plurality, so that the heat exchange medium can absorb the heat or cold generated by the gadolinium element 4 more uniformly and quickly.

[0084] Assuming that two first dynamic ends of the first inlet pipe 511 and two second dynamic ends of the second inlet pipe 521 are provided, the first dynamic end of the first outlet pipe 512 is provided between the two first dynamic ends, and the first dynamic end of the second outlet pipe 522 is provided between the two second dynamic ends. In this way, there are three dynamic ends in both the hot end 21 and the cold end, and the three dynamic ends are preferably evenly distributed, so that the heat or cold generated by the gadolinium element 4 can be better taken away.

[0085] In addition, multiple inlets of the first dynamic ends are connected to the corresponding first static ends after being gathered together, and multiple inlets of the second dynamic ends are connected to the corresponding second static ends after being gathered together, that is, no matter how many first dynamic ends of the first inlet pipe 511 and how many second dynamic ends of the second inlet pipe 521 are set, there is only one corresponding static end.

[0086] In a specific embodiment, Fig.14 As shown, the magnetic field component 1 is an arc-shaped permanent magnet with an opening on one side, the magnetic regenerative body component 2 is a circular ring with an opening on one side and a cavity, the gadolinium element 4 is filled in the cavity, and one end of the magnetic regenerative body component 2 is located in the arc-shaped permanent magnet through the opening.

[0087] Specifically, the magnetic regenerative body component 2 is open on one side and sealed on the other side, and the gadolinium element 4 is filled into the cavity through the opening. In order to better fix the gadolinium element 4, the cavity can be divided into several parts. The magnetic field component 1 is a permanent magnet, which can be one-third of a circle or one-half of a circle, and is not specifically limited here. The magnetic regenerative body component 2 is open on three sides and has a certain thickness. One end of the magnetic regenerative body component 2 can be located in the permanent magnet through the opening, so that the magnetic field generated by the permanent magnet acts on the gadolinium element.

[0089] This embodiment provides a transport box, which includes a box assembly 6 and the temperature adjustment device described in Embodiment 1, and the temperature adjustment device is arranged in the box assembly.

[0090] In a specific embodiment, Fig.19 As shown, the box assembly 6 includes a box body 61 and a box cover 62 movably arranged on the box body 61, and the box body 61 has a partition 63, and the partition 63 divides the space in the box body 61 into a heat-insulating space and a refrigerated space. The hot end 21 is located in the heat-insulating space, and the cold end 22 is located in the refrigerated space.

[0091] In this embodiment, the transport box can be a take-out box for delivering take-out food, or a medicine box for transporting human body fluids, tissue specimens or medicines. When it is a take-out box, the heat preservation space can keep the food warm, and the refrigeration space can be used to place some ice drinks and other foods that need to be refrigerated. When it is used as a medicine box, the refrigeration space generally has a higher utilization rate, and human body fluids, tissue specimens or medicines that need to be refrigerated can be placed in the refrigeration space.

[0092] The transport box provided in this embodiment adopts the temperature regulating device in Example 1, so that the transport box can move any items that need to be heated or refrigerated. Compared with the traditional method of insulation or refrigeration with a layer of insulation paper, this embodiment obviously has better effect.
