Description

Technical Field

[0001] This invention relates to the field of medical hot and cold compress devices, and more specifically, to a vehicle-mounted semiconductor temperature-controlled hot and cold compress therapy device. Background Technology

[0002] Soldiers are prone to acute closed injuries such as bone and joint injuries or soft tissue damage in field conditions. These injuries require prompt treatment to prevent further harm. When joints or soft tissues are injured, swelling occurs at the site of injury, causing severe pain. To stop bleeding, relieve pain, and reduce swelling, cold or hot compresses should be applied to the injured area as soon as possible. The more timely the treatment, the better the outcome and the shorter the treatment time.

[0003] However, in the wild, it is difficult to equip oneself with hot and cold compress therapy devices. Current technology usually only uses simple methods such as ice cubes or hot water bottles to achieve hot or cold compresses. These simple methods are not only less effective and the temperature is uncontrollable, but also have a short duration, making it impossible to achieve continuous hot or cold compress therapy. Medical staff need to frequently replace ice cubes or hot water bottles, which increases the workload of medical staff and is inconvenient to use. On the other hand, some devices that can achieve hot and cold compress therapy are large and inconvenient to carry, which greatly reduces their portability in the wild. Therefore, most injured people in the wild miss the best time for treatment because they cannot receive timely treatment. Summary of the Invention

[0016] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0017] In the above solution, by setting up a hot and cold compress component, firstly, compared with the existing technology of simply using ice cubes or hot water bottles for hot and cold compresses, its hot and cold compress effect is better, the temperature of the hot and cold compresses is controllable, and it can be used for a long time without medical staff having to frequently replace ice cubes or hot water bottles, thus reducing the labor intensity of medical staff and making it more convenient to use. At the same time, this device can be mounted on a vehicle, and can be easily transported to field rescue points using ambulances, greatly improving its portability and reducing the occurrence of most field injured people missing the best time for treatment due to the inability to receive timely treatment under the current conditions.

[0018] By incorporating an energy recovery component, when the PN junction heating and cooling generator is operating, the energy released at its lower end is transferred through the heating and cooling component to a semi-elliptical heat conductor on the energy recovery component. The semi-elliptical heat conductor is shaped to fit the heating and cooling component, allowing for better transfer of cold or heat to the thermoelectric generator. The thermoelectric generator receives the transferred cold or heat and begins to operate, outputting electrical energy. After being inverted by the inverter, the electrical energy is stored in the battery. This electrical energy can power the motor for switching operations and other electrical applications on the equipment, thus utilizing the energy dissipated from the non-operating end of the PN junction heating and cooling generator and reducing energy waste.

[0019] By setting up a clamping component, when the motor flips to switch between hot and cold compresses, the rotation of the shaft will drive the rotating drum to rotate, and the rotation of the drum will drive the elliptical protrusion fixed to it to rotate. During the 180-degree rotation, since the return spring is set to be in a stretched state throughout the process, except when the two ends of the elliptical protrusion are pressed against the top rod, the return spring will drive the telescopic rod to retract when rotating in other positions, and drive the PN junction hot and cold generating component and the hot and cold compress support to rise to a certain height, so as to ensure the smooth flipping of the hot and cold compress support and not be blocked by the semi-elliptical heat conductor. When the two ends of the elliptical protrusion are pressed against the top rod, the combination of the PN junction hot and cold generating component and the hot and cold compress support is exactly in a vertical position, thereby squeezing the semi-elliptical heat conductor and ensuring the power generation effect of the energy recovery component.

[0020] By setting up a hot and cold compress support section, firstly, according to the limb part that the patient needs to apply hot and cold compresses to, the adjustment handle is rotated to drive the bidirectional screw to rotate. The two ends of the bidirectional screw are symmetrically connected to ball nut seats. When the bidirectional screw rotates, the two ball nut seats will move closer to each other or further away from each other inside the adjustment groove, thereby driving the left half support body and the right half support body to move closer to each other or further away from each other. This achieves the adjustment of the opening size of the hot and cold compress support section, so as to ensure that different limb parts can be placed, thus improving the applicability of the device.

[0041] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should also be noted that, to make the embodiments more comprehensive, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0042] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0043] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0044] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0045] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0046] like Figures 1 to 10 As shown, this embodiment of the invention provides a vehicle-mounted semiconductor temperature-controlled hot and cold compress therapy device, including a device housing 1; a reclining pad 4 is provided on the upper end of the device housing 1, and a hot and cold compress component 5 for providing hot and cold compress energy is provided on one side of the upper surface of the device housing 1 near the reclining pad 4; a control console 2 is also provided on one end of the upper surface of the device housing 1, and a fixing bolt 3 for connecting and fixing the device housing 1 to the vehicle is fixedly installed on one side of the control console 2; the hot and cold compress component 5 includes a motor 51 provided on the front side of the device housing 1, and a rotating shaft 52 is fixedly connected to the output end of the motor 51; a PN junction hot and cold compress generating component 57 is fixedly provided at the middle position of the outer circular surface of the rotating shaft 52; hot and cold compress support parts 56 are provided at both the upper and lower ends of the PN junction hot and cold compress generating component 57.

[0047] like Figure 6 As shown, the PN junction cooling and heating generation component 57 includes a housing 571 fixed to the outer circular surface of the rotating shaft 52. The upper and lower ends of the housing 571 are respectively provided with a cold end 573 and a hot end 572. Several sets of cold end metal sheet conductors 574 are provided inside the housing 571 in close contact with the cold end 573, and several sets of hot end metal sheet conductors 575 are provided inside the housing 571 in close contact with the hot end 572. Multiple sets of N-type semiconductors 576 and P-type semiconductors 577 are electrically connected between the cold end metal sheet conductors 574 and the hot end metal sheet conductors 575. The PN junction cooling and heating generation component 57 also includes an energy recovery component 54 fixed to the inner wall of the equipment housing 1.

[0048] The number of cold-end metal sheet conductors 574 is greater than the number of hot-end metal sheet conductors 575, and the cold-end metal sheet conductors 574 and hot-end metal sheet conductors 575 are arranged symmetrically about both sides of the rotating shaft 52. Two adjacent N-type semiconductors 576 and P-type semiconductors 577 electrically connected to the same cold-end metal sheet conductor 574 form a PN junction. The lower ends of the N-type semiconductors 576 and P-type semiconductors 577 in the PN junction are electrically connected to the two adjacent sets of hot-end metal sheet conductors 575, so that the entire N-type semiconductor 576 and P-type semiconductor 577, cold-end metal sheet conductors 574 and hot-end metal sheet conductors 575 together form a series circuit, and are electrically connected to the vehicle power supply through the two sets of hot-end metal sheet conductors 575 at both ends.

[0049] Both the cold end 573 and the hot end 572 are made of insulating ceramic sheets.

[0050] When using the hot and cold compress device, firstly, move the device into the ambulance using rollers and fix it with fixing bolts 3. After the ambulance moves and arrives at the field rescue location, move the patient onto the hot and cold compress device. If the patient has a soft tissue injury to the head and neck, place the patient on the lying mat 4 and place the neck on the hot and cold compress support 56 for treatment. If the patient has a soft tissue injury to the limbs, choose a suitable position and place the injured parts of the limbs on the hot and cold compress support 56 for hot and cold compress treatment.

[0051] During treatment, the motor 51 is controlled by the console 2 to rotate the shaft 52, thereby causing the PN junction hot / cold generating component 57 and its upper and lower hot / cold compress support parts 56 to rotate, allowing for the selection of hot / cold compresses. Figure 4 Under these conditions, the upper hot and cold compress support 56 is the cold end and can provide cold compress, while the lower hot and cold compress support 56 is the hot end and can provide hot compress; (It should be noted that the maximum rotation angle of the PN junction hot and cold compress generating component 57 and the hot and cold compress support 56 installed at its upper and lower ends is 180 degrees. When the hot and cold compress is replaced later, it will return to its original position, so the wires connected to the PN junction hot and cold compress generating component 57 will not get tangled or anything like that).

[0052] When the PN junction thermal generator 57 is in operation, the circuit connected to the PN junction thermal generator 57 is energized via the control console 2, and the current is sequentially... Figure 8The described path begins with current flowing into the hot-end metal conductor 575, passing through the N-type semiconductor 576 and being guided to the upper cold-end metal conductor 574. It then flows into the P-type semiconductor 577, which is electrically connected to the cold-end metal conductor 574, and from there into another set of hot-end metal conductors 575. This current flow path is repeated, the specific number of times determined by the number of PN junctions. After completing the circuit flow, the current exits through the hot-end metal conductor 575 at the end. During this process, according to the Peltier effect, the specific details are as follows:

[0053] The Peltier effect is the phenomenon where, when an electric current flows through the junction of two different metals, one junction absorbs heat while the other releases heat. This phenomenon was first discovered by the French physicist Franz Peltier in 1834, hence its name. In semiconductors, N-type and P-type semiconductors can be formed by doping with different impurity elements. N-type semiconductors conduct electricity primarily through free electrons, while P-type semiconductors conduct electricity primarily through holes. When these two types of semiconductors combine to form a PN junction, the flow of current will produce heat absorption or release at the PN junction. Specifically, when current flows from an N-type semiconductor to a P-type semiconductor, one junction absorbs heat, resulting in cooling; conversely, when current flows from a P-type semiconductor to an N-type semiconductor, the junction releases heat, resulting in heating.

[0054] It can be seen that, in Figure 8 As shown in the figure, the upper cold end 573 will achieve the cooling effect, while the lower hot end 572 will achieve the heating effect. The degree of cooling and heating can be controlled by controlling the current. The outer shell 571 is made of thermally conductive material. The cold energy of the cold end 573 will be transferred to the hot and cold compress support part 56 through the outer shell 571 to apply cold compress to the patient. If hot compress is to be achieved, the motor 51 will be started to rotate the shaft 52.

[0055] This application, by incorporating a hot and cold compress component 5, offers several advantages. Firstly, compared to existing technologies that simply use ice or hot water bottles for hot and cold compresses, this component provides a more effective and controllable hot and cold compress. It can also be used for extended periods without requiring frequent replacement of ice or hot water bottles by medical personnel, thus reducing their workload and making it more convenient to use. Secondly, this device can be mounted on a vehicle, allowing for easy access to field rescue points via ambulance. This significantly improves portability and reduces the likelihood of most injured individuals in the wild missing their optimal treatment window due to the inability to receive timely medical care under current conditions.

[0056] like Figure 7As shown, the energy recovery component 54 includes a fixing plate 541 fixedly installed on the inner wall of the equipment housing 1. A battery 542 is provided on one side of the upper end of the fixing plate 541. An inverter 543 is also provided on the upper end of the fixing plate 541. A thermoelectric generator 545 is fixedly connected to the end of the fixing plate 541. A semi-elliptical heat conductor 544 is fixedly connected to the upper surface of the thermoelectric generator 545.

[0057] When the PN junction heat generator 57 is working, only the upper end is the working end. The cold or heat released from the lower end cannot be utilized and can only diffuse into the air, resulting in energy waste. In this application, by setting up an energy recovery component 54, when the PN junction heat generator 57 is working, the energy released from the lower end is transferred through the heat-cooling support 56 to the semi-elliptical heat conductor 544 on the energy recovery component 54. The shape of the semi-elliptical heat conductor 544 fits the heat-cooling support 56, which can better transfer the cold or heat to the thermoelectric generator 545. The thermoelectric generator 545 receives the transferred cold or heat and starts to work, and outputs electrical energy. After being inverted by the inverter 543, the electrical energy is stored in the battery 542. This electrical energy can be used to power the motor 51 for switching operations and other electrical applications on the equipment, so that the energy emitted from the non-working end of the PN junction heat generator 57 is utilized, reducing energy waste.

[0058] The thermoelectric generator 545 is existing technology, which mainly uses temperature difference to generate electricity, and will not be elaborated here. It should be noted that when the cold end 573 is in contact with the semi-elliptical heat conductor 544, the temperature of the upper surface of the thermoelectric generator 545 is lower, and a temperature difference is generated between the upper surface of the thermoelectric generator 545 and the lower surface (in contact with the air), thereby generating electricity. At this time, the air is equivalent to the heat source. When the hot end 572 is in contact with the semi-elliptical heat conductor 544, the temperature of the upper surface of the thermoelectric generator 545 is higher, and a temperature difference is generated between the upper surface of the thermoelectric generator 545 and the lower surface (in contact with the air), thereby generating electricity. At this time, the air is equivalent to the cold source.

[0059] like Figure 4 and Figure 8As shown, both ends of the rotating shaft 52 are provided with pressing components 55, which can drive the PN junction hot and cold generation component 57 and the hot and cold compress support part 56 to press down and press against the semi-elliptical heat conductor 544; the pressing component 55 includes a rotating cylinder 551 fixedly sleeved on the outer circular surface of the rotating shaft 52. Both ends of the outer circular surface of the rotating cylinder 551 are provided with annular grooves 553. Sliding sliders 554 are slidably connected inside the two annular grooves 553. One end of the slider 554 is fixedly connected to a telescopic rod 555, and the upper end of the telescopic rod 555 is fixedly connected to the top wall of the equipment housing 1. The bottom of the telescopic rod 555 is fixedly connected to a return spring 557, and the top of the return spring 557 is fixedly connected to the top wall of the equipment housing 1; an elliptical protrusion 552 is fixedly connected to the middle position of the outer circular surface of the rotating cylinder 551, and a top rod 556 is fixedly connected to the top wall of the equipment housing 1 at the position corresponding to the elliptical protrusion 552.

[0060] The clamping assembly 55 also includes a movable groove 53 opened on the front side of the equipment housing 1. Both sides of the movable groove 53 are fixedly connected to slide rods 58. The outer surfaces of the two slide rods 58 slide together to engage with the sliding mounting body 59. The motor 51 is fixedly installed on the sliding mounting body 59, and the rotating shaft 52 is rotatably installed through the sliding mounting body 59.

[0061] When the energy recovery component 54 is working, the hot and cold compress support 56 needs to press against the semi-elliptical heat conductor 544 to generate sufficient pressure on the thermoelectric generator 545, ensuring the power generation effect of the thermoelectric generator 545 (pressure is one of the key factors affecting the power generation effect of the thermoelectric generator 545; the greater the pressure, the greater the power generation). This application, by setting up the pressing component 55, ensures that when the motor 51 flips to switch between hot and cold compress, the rotation of the shaft 52 will drive the rotating drum 551 to rotate. Because the rotating drum 551 and the telescopic rod 555 are rotatably connected through the annular groove 553 and the slider 554, the telescopic rod 555 will not rotate accordingly. However, the rotation of the rotating drum 551 will drive the elliptical protrusion 552 fixed to it to rotate. After a 180-degree rotation... During the process, since the return spring 557 is set to be in a stretched state throughout the entire process, except when the two ends of the elliptical protrusion 552 are pressed against the top rod 556, when rotating in other positions, the return spring 557 will drive the telescopic rod 555 to retract, and drive the PN junction heat generation component 57 and the heat and cold compress support 56 to rise to a certain height, so as to ensure that the heat and cold compress support 56 can be flipped smoothly and will not be blocked by the semi-elliptical heat conductor 544. When the two ends of the elliptical protrusion 552 are pressed against the top rod 556, the combination of the PN junction heat generation component 57 and the heat and cold compress support 56 is exactly in a vertical position, thereby achieving the compression of the semi-elliptical heat conductor 544 and ensuring the power generation effect of the energy recovery component 54.

[0062] like Figure 3 and Figure 10As shown, the hot and cold compress support 56 includes an adjustment groove 561 formed on the outer shell 571. A bidirectional lead screw 563 is rotatably connected inside the adjustment groove 561, and one end of the bidirectional lead screw 563 extends to the outside of the outer shell 571 and is fixedly connected to an adjustment handle. Two sets of ball nut seats 562 are symmetrically slidably connected to both sides of the outer circular surface of the bidirectional lead screw 563, and the two sets of ball nut seats 562 slide inside the adjustment groove 561. The upper ends of the two sets of ball nut seats 562 are respectively fixedly connected to the left half support body 5610 and the right half support body 569. A gap filling component and a gas encapsulation layer component are also provided between the right half support body 569 and the left half support body 5610.

[0063] The height of the ball nut seat 562 is flush with the height of the adjusting groove 561 to ensure that the bottom of the left half support 5610 and the right half support 569 are in contact with the outer shell 571, so as to facilitate the smooth transmission of energy.

[0064] By setting up the hot and cold compress support part 56, when in use, first, according to the limb part that needs hot and cold compress, rotate the adjustment handle to drive the bidirectional screw 563 to rotate. The two ends of the bidirectional screw 563 are symmetrically connected to the ball nut seats 562. When the bidirectional screw 563 rotates, the two ball nut seats 562 will move closer to each other or further away from each other inside the adjustment groove 561, thereby driving the left half support body 5610 and the right half support body 569 to move closer to each other or further away. This achieves the adjustment of the opening size of the hot and cold compress support part 56 to ensure that different limb parts can be placed, thus improving the applicability of the device. In addition, the right half support body 569 and the left half support body 5610 are both made of heat-conducting metal, which can transfer heat and cold.

[0065] like Figure 10 As shown, the gap filling assembly includes a medium water storage box 564 fixedly connected to one side of the right half support body 569, a medium water storage cavity 566 provided in the middle of the left half support body 5610 and the right half support body 569, and a flow channel 565 provided inside the right half support body 569 for the medium water storage box 564 and the medium water storage cavity 566 to communicate with each other; the medium water storage cavity 566 is composed of the middle cavity of the left half support body 5610 and the right half support body 569 and a closed rubber diaphragm 567 fixedly connected around the middle cavity by the left half support body 5610 and the right half support body 569.

[0066] After adjusting the opening size of the left half-support body 5610 and the right half-support body 569 in the hot and cold compress support section 56, a gap appears between the left half-support body 5610 and the right half-support body 569. When a limb is placed inside, some areas may not be able to receive cold or hot compresses. To address this issue, this application provides a gap-filling component. When the left half-support body 5610 and the right half-support body 569 move away from each other, the medium water storage chamber 566 opens. Because the volume of the medium water storage box 564 is twice the maximum volume of the medium water storage chamber 566 (the maximum opening angle of the left half-support body 5610 and the right half-support body 569), and the height of the medium water storage box 564 is greater than that of the medium water storage chamber 566, the medium water storage box 564, under the influence of gravity, allows the medium water storage chamber 569 to open. The medium water flows from the medium water storage box 564 into the medium water storage cavity 566 through the flow channel 565 and fills the medium water storage cavity 566. At this time, the left half support body 5610 and the right half support body 569 will be filled with medium water. Water can act as a good heat and cold conduction medium, which can transfer heat and cold to the limbs, ensuring that there will be no problem of some limbs being unable to accept cold or hot compresses after adjustment. When the left half support body 5610 and the right half support body 569 approach each other, the medium water inside the medium water storage cavity 566 will be squeezed and return to the medium water storage box 564 through the flow channel 565, ensuring that the left half support body 5610 and the right half support body 569 can close normally.

[0067] like Figure 10 As shown, the gas encapsulation layer assembly includes a blower 568 fixedly connected to the outside of the left half support 5610 and the right half support 569. S-shaped heat exchange channels 5611 are provided inside both the left half support 5610 and the right half support 569, and the blower 568 is interconnected with the S-shaped heat exchange channels 5611. Dispersion shells 5612 are fixedly connected to the top of both the left half support 5610 and the right half support 569. Dispersion chambers 5613 are provided inside each of the dispersion shells, and uniformly distributed hot and cold air outlets 5614 are provided on the opposite sidewalls of the two dispersion shells. The two dispersion chambers 5613 are interconnected with the two S-shaped heat exchange channels 5611 through channels provided inside the left half support 5610 and the right half support 569, respectively.

[0068] When in use, the hot and cold compress support 56 cannot achieve a wrap-around cold or hot compress on soft tissue because its upper opening is unobstructed. Therefore, by setting up a gas wrapping layer component, the battery 542 can power the blower 568 to blow outside air into the S-shaped heat exchange channel 5611. After exchanging cold or heat with the left half support body 5610 and the right half support body 569, the air becomes cold or hot air and is blown out from the cold or hot air outlet 5614 through the dispersion chamber 5613. This achieves the wrap-around blowing of cold or hot air on the upper opening of the hot and cold compress support 56, thus enabling cold or hot compress on the soft tissue of the limb, improving the practicality of the hot and cold compress support 56. In addition, the cold or hot air outlet 5614 can be designed as a downward-sloping through hole to improve the wrap-around effect.

[0069] The working process of the technical solution provided by this invention is as follows:

[0070] In use, the device is first moved into the ambulance by rollers and fixed with fixing bolts 3. After the ambulance moves and arrives at the field rescue location, the patient is moved onto the hot and cold compress device. If the patient has a soft tissue injury to the head and neck, the patient is placed on the lying mat 4 and the neck is placed on the hot and cold compress support 56 for treatment. If the patient has a soft tissue injury to the limbs, a suitable position is selected and the injured parts of the limbs are placed on the hot and cold compress support 56 for hot and cold compress treatment.

[0071] During treatment, the motor 51 is controlled by the console 2 to rotate the shaft 52, thereby causing the PN junction hot / cold generating component 57 and its upper and lower hot / cold compress support parts 56 to rotate, allowing for the selection of hot / cold compresses. Figure 4 Under these conditions, the upper hot and cold compress support part 56 is the cold end and can provide cold compress, while the lower hot and cold compress support part 56 is the hot end and can provide hot compress.

[0072] When the PN junction heat generation component 57 is working, the energy released at the lower end is transferred through the heat and cold support 56 to the semi-elliptical heat conductor 544 on the energy recovery component 54. The shape of the semi-elliptical heat conductor 544 fits the heat and cold support 56, which can better transfer cold or heat to the thermoelectric generator 545. The thermoelectric generator 545 receives the transferred cold or heat and starts to work, and outputs electrical energy. After being inverted by the inverter 543, the electrical energy is stored in the battery 542. This electrical energy can be used to power the motor 51 for switching operations and other electrical applications on the equipment, so that the energy emitted from the non-working end of the PN junction heat generation component 57 is utilized, reducing energy waste.

[0073] By setting the clamping component 55, when the motor 51 flips to switch between hot and cold compress, the rotation of the rotating shaft 52 will drive the rotating drum 551 to rotate. Since the rotating drum 551 and the telescopic rod 555 are rotatably connected through the annular groove 553 and the slider 554, the telescopic rod 555 will not rotate with it. However, the rotation of the rotating drum 551 will drive the elliptical protrusion 552 fixed to it to rotate. During the 180-degree rotation, since the return spring 557 is set to be in a stretched state throughout the process, except when the two ends of the elliptical protrusion 552 are pressed against the top rod 556, the rotation will not be affected. When rotating to other positions, the return spring 557 will cause the telescopic rod 555 to retract, and cause the PN junction hot and cold generation component 57 and the hot and cold support part 56 to rise to a certain height, so as to ensure that the hot and cold support part 56 can be rotated smoothly and will not be blocked by the semi-elliptical heat conductor 544. When the two ends of the elliptical protrusion 552 are pressed against the top rod 556, the combination of the PN junction hot and cold generation component 57 and the hot and cold support part 56 is exactly in a vertical position, thereby squeezing the semi-elliptical heat conductor 544 and ensuring the power generation effect of the energy recovery component 54.
