Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to a vacuum energy-saving conductor. Background Technology

[0002] Among the current types of heating devices, superconducting heating devices are taking up an increasingly larger market share. Given that the vacuum heating method they use is a globally recognized environmentally friendly and energy-saving heating technology, superconducting heating devices have huge market potential.

[0003] In residential heating applications, superconducting heating devices often achieve heating by contacting heated circulating water. Especially in northern regions during winter, superconducting heating devices are often installed on the circulating water pipes of centralized heating systems. However, the location of the water pipes in contact with the superconducting heating devices means that their installation location cannot be adjusted, limiting their application scenarios.

[0004] Therefore, how to provide a vacuum energy-saving conductor that facilitates the adjustment of the setting position of superconducting heating devices to adapt to more application scenarios is an urgent technical problem to be solved. Utility Model Content

[0005] This invention provides a vacuum energy-saving conductor, which solves the problem that the setting position of superconducting heating devices cannot be adjusted and the application scenarios are limited.

[0006] This utility model provides a vacuum energy-saving conductor, comprising: a device body, the interior of which is a vacuum cavity, the device body including a heating tube, a heat source column and a connecting frame, the heat source column being two, the two heat source columns being respectively connected to the heating tube through the connecting frame, the connecting frame being two sets, each set of the connecting frame being evenly arranged between the heating tube and the heat source column;

[0007] A superconducting medium, wherein the superconducting medium is located at the bottom of the vacuum cavity;

[0008] The base has casters at its bottom and an internal space for holding the device body and heating element. A locking assembly is provided on the base, and the base is connected to the device body via the locking assembly.

[0009] In one possible implementation, the connecting frame includes an upper connecting frame and a lower connecting frame, the upper connecting frame being disposed on the heating tube, the lower connecting frame being disposed on the heat source column, and the connection between the upper connecting frame and the lower connecting frame having a bend.

[0010] In one possible implementation, the top wall of the base is provided with a first through hole, the size of which corresponds to the size of the heat source column. An abutment plate is provided on the connecting lower frame. When the heat source column is located in the accommodating space, the bottom surface of the abutment plate abuts against the outer side of the top wall of the base.

[0011] In one possible implementation, the locking assembly includes a limiting block disposed on the outer side of the top wall of the base, and the limiting block is provided with a first limiting groove. When the heat source column is located in the accommodating space, the first limiting groove engages with the abutment plate.

[0012] In one possible implementation, the locking assembly further includes a cover plate with a sliding groove, and a slider on the outer side of the top wall of the base. The sliding groove cooperates with the slider so that the cover plate slides on the top wall of the base. The cover plate is provided with a second limiting groove, which engages with the abutment plate when the heat source column is located in the accommodating space.

[0013] In one possible implementation, the top wall of the base is provided with a second through hole, the second through hole is connected to the first through hole, the size of the second through hole is smaller than that of the first through hole, the limiting block is provided on the outer side of the top wall of the base and close to the side of the second through hole, and the cover plate is provided on the outer side of the top wall of the base and close to the side of the first through hole.

[0014] In one possible implementation, the locking assembly further includes a limiting rod, on which a first return spring and a first limiting stop are provided. The limiting rod is disposed on the cover plate, and the limiting block is provided with a limiting hole. When the first limiting stop passes through the limiting hole, the first limiting stop prevents the limiting rod from retracting.

[0015] In one possible implementation, the limiting rod is provided with a second return spring and a second limiting stop, wherein when the first limiting stop passes through the limiting hole, the second limiting stop prevents the limiting rod from advancing.

[0016] In one possible implementation, the heating component includes a heating plate and an electric heating tube. The heating plate is disposed at the bottom of the accommodating space and is used to heat the water in the accommodating space so that the water transfers heat to the heat source column. The electric heating tube is disposed below the heating plate and provides heat to the heating plate.

[0017] One possible implementation further includes a temperature sensor and a controller. The temperature sensor is disposed within the accommodating space and connected to the controller, which is disposed on the device body. The controller is used to control the energizing state of the heating element.

[0018] The beneficial effects of this invention are as follows: First, the device body is fixed to the base by the locking assembly. The heating assembly is then activated, transferring heat to the heat source column. The heat source column activates the superconducting medium within the vacuum chamber, causing the superconducting medium to heat up and rapidly vaporize, moving from the heat source column to the heating tube. Then, the high-temperature superconducting medium gas radiates heat outwards through the surface of the heating tube, transferring heat to the indoor environment for heating. Subsequently, as the heat from the high-temperature superconducting medium gas dissipates, it gradually cools and condenses into a superconducting liquid, flowing back to the bottom of the heat source column under gravity. Finally, the condensed superconducting medium is reactivated by the heat source. This process of vaporization, heat dissipation, condensation, and recirculation repeats, forming a continuous cycle that continuously transfers heat for sustained heating. The combination of the device body, locking assembly, base, and heating assembly forms an integrated, movable superconducting heat dissipation device, solving the problems of the inability to adjust the location of superconducting heating devices and their limited application scenarios.

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] See Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 9 This utility model provides a technical solution: a vacuum energy-saving conductor, comprising: a device body 1, the interior of which is a vacuum cavity 2, the device body 1 including a heating tube 101, a heat source column 102 and a connecting frame 103, two heat source columns 102, the two heat source columns 102 being connected to the heating tube 101 respectively through the connecting frame 103, two sets of connecting frames 103 being evenly arranged between the heating tube 101 and the heat source column 102, a superconducting medium 3, the superconducting medium 3 being located at the bottom of the vacuum cavity 2, a base 4, the bottom of the base 4 being provided with a pulley 22, the base 4 having an accommodating space 5, the accommodating space 5 being used to place the device body 1 and the heating component 6, the base 4 being provided with a locking component 7, the base 4 being connected to the device body 1 through the locking component 7.

[0035] The heating element 101 is interconnected with the connecting frame 103, and the heat source column 102 is interconnected with the connecting frame 103. Preferably, each set of connecting frames 103 has three columns and each set of heat source columns 102 has two columns. The two sets of connecting frames 103 and the two heat source columns 102 are arranged symmetrically about the vertical cross-section of the center of the heating element 101. The heating element 101 is cylindrical, and the heat source column 102 is prism, preferably a quadrangular prism. The cylindrical shape of the heating element 101 helps to increase the contact area between the heating element 101 and the superconducting medium 3, thereby improving the heat exchange efficiency and allowing heat to be transferred more quickly from the superconducting medium 3 to the outside of the heating element 101, thus accelerating the heating rate of the room.

[0036] Specifically, firstly, the device body 1 is fixed to the base 4 by the locking assembly 7. Then, the heating assembly 6 is activated, transferring heat to the heat source column 102. The heat source column 102 activates the superconducting medium 3 within the vacuum chamber 2. The superconducting medium 3 heats up and rapidly vaporizes, moving from the heat source column 102 to the heating tube 101. Then, the high-temperature superconducting medium 3 gas radiates heat outwards through the surface of the heating tube 101, transferring heat to the indoor environment to achieve the purpose of heating. Afterwards, as the heat of the high-temperature superconducting medium 3 gas dissipates, it gradually cools and condenses into a superconducting medium 3 liquid, flowing back to the bottom of the heat source column 102 under the influence of gravity. The pulleys 22 on the base 4 increase the ease of movement of the base 4.

[0037] It should be noted that the superconducting medium 3 is a specially prepared composite chemical liquid, preferably a mixture of potassium sulfate (chemically pure), potassium dichromate (chemically pure) and double-distilled water. This application does not limit or improve the superconducting medium 3.

[0038] See Figure 2 In some embodiments, the connecting frame 103 includes an upper connecting frame 1031 and a lower connecting frame 1032. The upper connecting frame 1031 is disposed on the heating tube 101, and the lower connecting frame 1032 is disposed on the heat source column 102. The connection between the upper connecting frame 1031 and the lower connecting frame 1032 has a bend. The bend design reduces the height of the device body 1, making the placement of the base 4 and the device body 1 more flexible, better matching the indoor layout, and avoiding conflicts with the building structure or other furniture.

[0039] In some embodiments, the top wall of the base 4 is provided with a first through hole 8, the size of which corresponds to the size of the heat source column 102. A connecting lower frame 1032 is provided with an abutment plate 9. When the heat source column 102 is located in the accommodating space 5, the bottom surface of the abutment plate 9 abuts against the outer side of the top wall of the base 4. The size of the first through hole 8 corresponds to the size of the horizontal cross section of the heat source column 102. The heat source column 102 can pass vertically through the first through hole 8 to enter the accommodating space 5. There are two first through holes 8, and the distance between the two first through holes 8 is slightly smaller than the distance between the two heat source columns 102.

[0040] In some embodiments, the locking assembly 7 includes a limiting block 701 disposed on the outer side of the top wall of the base 4. The limiting block 701 is provided with a first limiting groove 10. When the heat source column 102 is located in the accommodating space 5, the first limiting groove 10 engages with the abutment plate 9. Further, the locking assembly 7 also includes a cover plate 702. The cover plate 702 is provided with a sliding groove 11. A slider 12 is provided on the outer side of the top wall of the base 4. The sliding groove 11 cooperates with the slider 12 so that the cover plate 702 slides on the top wall of the base 4. The cover plate 702 is provided with a second limiting groove 13. When the heat source column 102 is located in the accommodating space 5, the second limiting groove 13 engages with the abutment plate 9.

[0041] Specifically, the heat source column 102 is aligned with the position of the first through hole 8, and then the device body 1 is moved down, the heat source column 102 enters the accommodating space 5, and then the device body 1 is moved towards the limiting block 701, so that the bottom surface of the abutment plate 9 abuts against the outer side of the top wall of the base 4. The cover plate 702 is moved towards the limiting block 701, and the first limiting groove 10 and the second limiting groove 13 respectively engage the two ends of the abutment plate 9.

[0042] See Figure 6 and Figure 7 In some embodiments, the top wall of the base 4 is provided with a second through hole 14, which is connected to the first through hole 8. The size of the second through hole 14 is smaller than that of the first through hole 8. The limiting block 701 is provided on the outer side of the top wall of the base 4 and close to the side of the second through hole 14. The cover plate 702 is provided on the outer side of the top wall of the base 4 and close to the side of the first through hole 8.

[0043] When the heat source column 102 enters the accommodating space 5 and moves the device body 1 towards the limiting block 701, the connecting lower frame 1032 enters the second through hole 14, the abutment plate 9 covers the second through hole 14, and the cover plate 702 covers the first through hole 8, which increases the sealing of the accommodating space 5 of the base 4 and reduces the heat loss in the accommodating space 5.

[0044] See Figure 7 and Figure 8 In some embodiments, the locking assembly 7 further includes a limiting rod 703, on which a first return spring 16 and a first limiting stop plate 17 are provided. The limiting rod 703 is disposed on the cover plate 702, and a limiting hole 15 is provided on the limiting block 701. When the first limiting stop plate 17 passes through the limiting hole 15, the first limiting stop plate 17 prevents the limiting rod 703 from retracting. Furthermore, the limiting rod 703 is provided with a second return spring 18 and a second limiting stop plate 19. When the first limiting stop plate 17 passes through the limiting hole 15, the second limiting stop plate 19 prevents the limiting rod 703 from advancing.

[0045] The first limiting baffle 17 and the second limiting baffle 19 are used to restrict the movement of the limiting rod 703 and the cover plate 702. When the cover plate 702 moves towards the limiting block 701, the limiting rod 703 passes through the limiting hole 15, and the first limiting baffle 17 retracts under force. When the first limiting baffle 17 passes through the limiting hole 15, the force of the first limiting baffle 17 return spring extends, and the first limiting baffle 17 and the second limiting baffle 19 respectively engage with the two opposite side walls of the limiting block 701.

[0046] When the device body 1 is separated from the base 4, the cover plate 702 moves towards the limiting block 701, pinches the second limiting baffle 19, and makes the second limiting baffle 19 pass through the limiting hole 15, so that the cover plate 702 covers the first through hole 8 and the second through hole 14, preventing water in the accommodating space 5 from splashing when the base 4 moves.

[0047] In some embodiments, the heating component 6 includes a heating plate 601 and an electric heating tube 602. The heating plate 601 is disposed at the bottom of the accommodating space 5 and is used to heat the water in the accommodating space 5 so that the water transfers heat to the heat source column 102. The electric heating tube 602 is disposed below the heating plate 601 and provides heat to the heating plate 601.

[0048] The heating element 602 is connected to an external power source. When the heating element 602 is powered on, it generates heat and then transfers the heat to the heating plate 601. The heating plate 601 then transfers the heat to the water in the containment space 5, forming a heat source.

[0049] It should be noted that the heating element 602 and the heating plate 601 are known devices, and this application has not made any improvements or limitations to them.

[0050] In some embodiments, the vacuum energy-saving conductor further includes a temperature sensor 20 and a controller 21. The temperature sensor 20 is disposed in the accommodating space 5 and connected to the controller 21. The controller 21 is disposed on the device body 1 and is used to control the power-on state of the heating element 602.

[0051] The temperature sensor 20 is used to detect the water temperature within the accommodating space 5 and sends a signal to the microcontroller 21. The microcontroller 21 adjusts the energizing state of the heating element. Preferably, the temperature sensor 20 is a DS18B20, and the microcontroller 21 is a KSD301 bimetallic strip limit thermostat. It should be noted that the information transmission and signal flow involved in the detection of the water temperature within the accommodating space 5 by the temperature sensor 20 and the sending of the signal to the microcontroller 21 are well-known to those skilled in the art and will not be elaborated upon here. Furthermore, this application does not make any improvements or limitations to the temperature sensor 20 or the microcontroller 21 themselves.

[0052] Work process

[0053] First, place the device body 1 on the base 4, with the heat source column 102 passing through the first through hole 8, and the bottom surface of the abutment plate 9 abutting the outer side of the top wall of the base 4.

[0054] Then, the device body 1 is moved toward the limiting block 701, the lower frame 1032 is connected to the second through hole 14, one end of the abutment plate 9 is engaged with the first limiting groove 10 of the limiting block 701, and the bottom surface of the abutment plate 9 covers the second through hole 14.

[0055] Next, the cover plate 702 is moved toward the limiting block 701, the slide groove 11 slides on the slider 12, one end of the limiting rod 703 enters the limiting hole 15, the first limiting baffle 17 is retracted by force and continues to move. When the first limiting baffle 17 passes through the limiting hole 15, the force of the first limiting baffle 17 return spring extends, and the first limiting baffle 17 and the second limiting baffle 19 respectively engage with the two opposite side walls of the limiting block 701.

[0056] Simultaneously, the second limiting groove 13 on the cover plate 702 engages with the other end of the abutment plate 9, and the cover plate 702 covers the first through hole 8.

[0057] Finally, the heating element 602 is energized, generating heat that is then transferred to the heating plate 601. The heating plate 601 then transfers the heat to the water in the containment space 5, forming a heat source. This heat source activates the superconducting medium 3 within the vacuum chamber 2, causing it to heat up and rapidly vaporize, moving from the heat source column 102 to the heating element 101. The high-temperature superconducting medium 3 gas then radiates heat outwards through the surface of the heating element 101, transferring heat to the indoor environment to achieve the purpose of heating.

[0058] During this process, the temperature sensor 20 is used to detect the water temperature in the container space 5 and send a signal to the microcontroller 21. The microcontroller 21 adjusts the power supply status of the heating element 602 to ensure that the water in the container space 5 is at a suitable temperature, avoids repeated heating of boiling water, and reduces the waste of power resources.
