Description

Technical Field

[0001] This invention relates to the field of temperature control technology, specifically to a constant temperature system for preventing dry burning. Background Technology

[0002] With societal progress and the accelerating pace of life, many people are seeking hobbies that can relax their minds and bodies, decorate their spaces, and improve their quality of life. Keeping aquatic life is one such hobby. Aquariums with constant temperature functions are favored by many fish enthusiasts because they can meet the needs of both tropical and cold-water fish. Therefore, many people choose aquariums with constant temperature functions when keeping fish. Currently, most aquariums on the market are square. These aquariums not only take up a lot of space but are also extremely inconvenient to change the water and clean. As aquariums develop towards miniaturization and desktop designs, more and more people hope to have aquariums that take up little space, are easy to change the water and clean, and have a constant temperature function, such as small round aquariums or tall cylindrical aquariums. However, existing small aquariums on the market usually achieve constant temperature by placing a heater at the opening. This design not only involves wires that affect the use of the lid but also takes up space for the aquatic creatures, thus affecting the overall aesthetics of the aquarium. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides an anti-dry-burning constant temperature system. Specifically, the technical solution adopted is as follows: An anti-dry-burning constant temperature system includes a container and a constant temperature system. The container has a through hole, and the constant temperature system includes a temperature regulating element and a temperature control element. The temperature regulating element is used for heating or cooling, and the temperature control element is used for measuring the temperature and controlling the operating state of the temperature regulating element according to the temperature. The temperature regulating element and the temperature control element are spaced apart inside the container and extend to the outside of the container through the through hole. When the temperature measured by the temperature control element reaches a threshold, the operation of the temperature regulating element is controlled to maintain a constant temperature inside the container.

[0004] Furthermore, when there is no liquid in the container, the temperature control device measures the temperature around the temperature control element and controls the operation of the temperature control element to prevent dry burning.

[0005] Furthermore, at least a portion of the temperature control element or temperature control device is located inside the container.

[0006] Furthermore, the temperature control group and / or temperature control device are spaced apart at the bottom or side of the container to reduce the impact on the activity space of aquatic organisms and improve the aesthetics.

[0007] Furthermore, the container is provided with at least one through hole, which is used to allow part of the body or wires of the temperature control element or temperature control device to extend outside the container.

[0008] Furthermore, the temperature regulating element can be a cooling element or a heating element to meet different temperature requirements.

[0009] Furthermore, the method for controlling the temperature regulating component using the temperature control device includes: relay control, solid-state relay, pulse width modulation, analog voltage control, current regulation, and circuit control.

[0010] Furthermore, the container has a base at its bottom, which is connected to the bottom of the container. The base can accommodate part of the main body or wires of the temperature control component and temperature control device, preventing damage caused by squeezing and friction, and protecting the container from bumps and knocks during daily placement.

[0011] Furthermore, the base is equipped with a power interface, which allows for quick connection or disconnection of the external power supply to the power interface when the aquarium needs to be cleaned or moved, facilitating operation.

[0012] By adopting the above technical solution, the beneficial effects of the present invention are: It features a simple structure and low cost, requiring only a temperature control element and a temperature control device to achieve a constant temperature effect. The temperature control device can control the operation of the temperature control element according to the ambient temperature to prevent dry burning. It solves the problem of small aquariums having anti-dry burning and constant temperature functions while occupying little space, reducing the impact on the activity space of aquatic organisms, not affecting the use of the tank lid, and improving the overall appearance of the aquarium. When the aquarium needs to be changed or moved, it can be quickly disconnected from the external power source through the power interface, making it easy to operate. In addition, the built-in temperature control element and temperature control device contribute to the miniaturization and desktop development of aquariums. Attached Figure Description

[0023] Reference Figures 1 to 4 This embodiment provides an anti-dry burning constant temperature system, including a container 6 and a temperature control system. The constant temperature system includes a temperature regulating component 1 and a temperature control component 2. The temperature regulating component 1 and the temperature control component 2 are spaced apart at the bottom of the container. In this embodiment, the container 6 is a circular cylinder with a through hole at the bottom.

[0024] In this embodiment, the temperature regulating component 1 is a ceramic heating element with a central hole for heating water. The temperature regulating component 1 is located at the bottom of the container 6 by a fixing component 3 and a fixing ring 4. The fixing component 3 is a cylindrical silicone material with elasticity and an annular flange at its upper end. The fixing ring 4 is annular with an inner diameter that matches the main body of the fixing component 3, allowing it to be fitted onto the main body of the fixing component 3 to fix the temperature regulating component 1 between the annular flange and the fixing ring 4. A temperature control device 2 is provided on the side of the fixing ring 4, spaced 1mm apart below the temperature regulating component 1 to facilitate the measurement of the temperature around the temperature regulating component 1. The lower end of the fixing component 3 is fixed at the through hole. Due to the elasticity of the fixing component 3, the wires of the temperature regulating component 1 and the temperature control device 2 can extend to the outside of the container 6 through the gap between the fixing component 3 and the through hole. In this embodiment, the fixing is done by adhesive bonding, ensuring airtightness while fixing.

[0025] In this embodiment, the temperature control device 2 is a normally closed KSD9700H temperature control switch with a temperature of 30 degrees Celsius. It has the characteristics of power-off when the temperature is too high and automatic power-on when the temperature drops by 5 degrees Celsius. Its surface is covered with insulating material to ensure insulation in water. The temperature control device 2 can react according to the measured temperature, disconnecting or connecting the circuit connected to the temperature control component 1, thereby controlling the operation of the temperature control component 1 and maintaining a constant water temperature.

[0026] The temperature control component 1 and the temperature control device 2 each have two wires. One of the wires of the temperature control device 2 is connected to one of the wires of the temperature control component 1. The other wire of the temperature control device 2 and the temperature control component 1 extends to the outside of the container 6 through the through hole at the bottom of the container 6. In this embodiment, the wiring points or gaps in the through holes inside the container 6 are coated with waterproof glue to ensure insulation and sealing in water.

[0027] A base 5 is provided at the bottom outside the container 6. The base 5 is a hollow cylinder that can accommodate wires. One end of the base 5 is glued to the bottom of the container 6. A power interface 7 is provided on the side of the base 5. In this embodiment, the power interface 7 is a DC female socket, which can be quickly connected or disconnected from an external DC male power supply, making it convenient to move or clean the container 6. The positive and negative terminals of the power interface 7 are respectively connected to the wires of the temperature control 2 and the temperature regulating component 1 extending to the outside of the container 6. In this embodiment, the wiring of the temperature regulating component 1 and the temperature control 2 has no distinction between positive and negative terminals.

[0028] When heating occurs in container 6 when there is no water, temperature control 2 can measure the temperature around temperature control component 1. When the measured temperature is higher than 30 degrees, temperature control 2 will automatically disconnect the circuit and stop the operation of temperature control component 1 to prevent dry burning. When heating occurs in container 6 when there is water, the heat from temperature control component 1 will be absorbed by the water. Temperature control 2 measures the temperature of the water. When the water temperature is higher than 30 degrees, temperature control 2 will disconnect the circuit and stop heating to maintain a constant water temperature. Example 2

[0029] Reference Figures 5 to 7 This embodiment provides an anti-dry burning constant temperature system, including a container 6 and a temperature control system. The constant temperature system includes a temperature regulating component 1 and a temperature control component 2. The temperature regulating component 1 and the temperature control component 2 are spaced apart at the bottom of the container. In this embodiment, the container 6 is a circular cylinder with a square through hole smaller than the size of the temperature regulating component 1 at the bottom, as well as a small through hole for fixing the temperature control component 2.

[0030] In this embodiment, the temperature regulating element 1 is a square semiconductor cooling chip that can cool the water. The temperature regulating element 1 is located outside the square through hole at the bottom of the container 6. When the temperature regulating element 1 is running, it cools and heats up simultaneously. The cooling surface of the temperature regulating element 1 faces the inside of the container. The size of the temperature regulating element 1 is larger than the square through hole, so the edges of the cooling surface of the temperature regulating element 1 can be fitted and fixed to the square through hole. The fitting is fixed and sealed with glue. The heating surface of the temperature regulating element 1 faces the outside of the container, and a small fan is provided on its heating surface as a heat dissipation component 10 for heat dissipation.

[0031] At the bottom of the container 6, there is a base 5 with open sides for ventilation. The base 5 is a hollow column. One end of the bottom surface of the base 5 is bonded to the bottom of the container 6. On the rear side of the base 5, there is a power interface 7 with a DC female connector. The power interface 7 can be quickly connected or disconnected from an external DC male connector, which facilitates the movement or cleaning of the container 6.

[0032] In this embodiment, the temperature control device 2 is a temperature probe with a connecting wire at one end. The temperature control device 2 is connected to a temperature control module 8 with a temperature display screen 9. The temperature control device 2 measures the temperature and feeds it back to the temperature control module 8 to control the operation of the temperature regulating component 1. The temperature control module 8 is located inside the base 5. The temperature control module 8 is provided with a power terminal 11, a temperature terminal 12, and a temperature regulating terminal 13. The power terminal 11 is connected to the power interface 7. The temperature terminal 12 is connected to the temperature control device 2. The temperature regulating terminal 13 is connected to both the temperature regulating component 1 and the heat sink 10 to ensure the synchronous operation of the temperature regulating component 1 and the heat sink 10. The temperature display screen 9 is located on the front side of the base 5 and can display the measured temperature.

[0033] The temperature control device 2 is vertically installed at the small through hole of the container 6, with one end of the connecting wire located outside the container 6 and the other end located inside the container 6. The temperature control device 2 and the temperature regulating component 1 are spaced apart so that the temperature control device 2 can measure the temperature around the temperature regulating component 1. When the temperature measured by the temperature control device 2 is higher than the rated value, the temperature regulating component 1 is controlled to start running. During the cooling process, the heat generated by the heating surface is discharged through the heat dissipation component 10.

[0034] When there is no water in container 6, the temperature is lowered. Since the cooling surface of the temperature regulating component 1 is in contact with the square through hole of container 6, the cold generated by the cooling surface will be conducted to the bottom of container 6. The temperature control device 2 controls the operation of the temperature regulating component 1 based on the measured temperature at the bottom of container 6. When the measured temperature is lower than the rated value, the temperature regulating component 1 is controlled to stop operating to prevent dry burning. When there is water in container 6, the water body will contact the cooling surface of the temperature regulating component 1 through the square through hole. At this time, the temperature regulating component 1 will cool the water body. Since the water body surrounds the temperature control device 2, the water body temperature is measured at this time. When the water body temperature is lower than the rated value, the operation of the temperature regulating component 1 is stopped. When the water body temperature is higher than the rated value, the operation of the temperature regulating component 1 is resumed.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
