[0023] To illustrate the technical solutions described in this application, specific embodiments are provided below, showing only the parts related to the embodiments of this application.

[0024] like Figures 1 to 2 As shown, this application provides a constant temperature system 1 for a fish tank 2, which may include:

[0025] The thermostat 10, the temperature control host 20, and the external water pipe 30 are included. The thermostat 10 may include a first temperature sensor 11 and a temperature control component 12. The temperature control host 20 may include a temperature control device 21, a control board 23, and a water tank 24.

[0026] In some embodiments, the first temperature sensor 11 and the thermostat assembly 12 can be placed in the fish tank 2 and in contact with the water; the thermostat assembly 12 is connected to the water tank 24 via an external water pipe 30, and the first temperature sensor 11 and the temperature control device 21 are both connected to the control board 23. For example, communication can be achieved via wired or wireless means. The thermostat assembly 12 can be a thermostat tube or a thermostat plate.

[0027] In some embodiments, the control board 23 can drive the temperature control device 21 to heat or cool the heat transfer medium in the temperature control device 21 or the heat transfer medium in the water tank 24 based on the temperature information obtained by the first temperature sensor 11. The treated heat transfer medium flows from the water tank 24 through the external water pipe 30 to the thermostatic component 12, and then flows back to the temperature control device 21 to maintain the temperature of the water in the fish tank 2. The temperature information obtained by the first temperature sensor 11 can refer to the temperature of the water in the fish tank 2. The heat transfer medium can be a coolant, a heat transfer fluid, or a cold transfer agent, etc. The thermostatic component 12 and the external water pipe 30 can be titanium alloy water pipes. The thermostatic component 12 and the external water pipe 30 can be an integrated structure or can be formed by splicing.

[0028] In some embodiments, the temperature control host 20 may further include a water pump 25 and a second temperature sensor 22. The external water pipe 30 includes a heat transfer medium supply pipe 31 and a heat transfer medium return pipe 32. One end of the heat transfer medium supply pipe 31 is connected to the water tank 24, one end of the heat transfer medium return pipe 32 is connected to one end of the water pump 25, and the other end of the water pump 25 is connected to the temperature control device 21 or the water tank 24. The other ends of the heat transfer medium supply pipe 31 and the other ends of the heat transfer medium return pipe 32 are both connected to the constant temperature component 12. The second temperature sensor 22 may be located in the water tank 24 and is connected to the control board 23. Specifically, the processed heat transfer medium starts from the water tank 24, enters the constant temperature component 12 through the heat transfer medium supply pipe 31, then flows from the constant temperature component 12 to the heat transfer medium return pipe 32 and the water pump 25, and finally returns to the temperature control device 21 or the water tank 24. This can be understood as one cycle, wherein the water pump 25 can be used to drive the circulation of the heat transfer medium. The second temperature sensor 22 can be used to obtain the temperature information of the heat transfer medium in the water tank 24. The control board 23 can drive the temperature control device 21 to heat up or cool down the heat transfer medium in the temperature control device 21 or the heat transfer medium in the water tank 24 based on the temperature information obtained by the first temperature sensor 11 and the second temperature sensor 22.

[0029] In some embodiments, an insulation layer 40 may be provided around the outer periphery of the external water pipe 30, and a protective layer 50 may also be provided around the outer periphery of the insulation layer 40. Both the insulation layer 40 and the protective layer 50 are tubular structures.

[0030] In some embodiments, such as Figure 1As shown, the temperature control device 21 includes a water-cooled plate 210, a thermoelectric cooler 211, and a heat sink 212. The water-cooled plate 210 can be connected to both the water pump 25 and the water tank 24. The water-cooled plate 210 is located on the cold side of the thermoelectric cooler 211, and the heat sink 212 is located on the hot side of the thermoelectric cooler 211. The thermoelectric cooler 211 is connected to the control board 23. The water-cooled plate 210 contains the heat transfer medium to be processed.

[0031] Specifically, the heat transfer medium to be processed flows back from the heat transfer medium return pipe 32 to the water-cooled plate 210 via the water pump 25. After the thermoelectric cooler 211 heats or cools the heat transfer medium, the processed heat transfer medium returns to the water tank 24. When the water temperature in the aquarium 2 is higher or lower than the preset temperature, the control board 23 can switch the current direction of the thermoelectric cooler 211 to be positive or negative to achieve the cooling or heating of the heat transfer medium to be processed in the water-cooled plate 210. The thermoelectric cooler 211 can be used to draw heat from the heat transfer medium in the water-cooled plate 210 to the heat sink 212, and the heat sink 212 can be used to diffuse the heat from the hot surface of the thermoelectric cooler 211, facilitating heat dissipation.

[0032] In some embodiments, the temperature control device 21 may further include a cooling fan 213, the air outlet of which may be directed toward the heat sink 212. This can further reduce the temperature of the heat sink 212.

[0033] In some embodiments, the thermostat 10 may further include a protective housing 13, with the first temperature sensor 11 and the thermostat component 12 located inside the protective housing 13. The protective housing 13 is provided with a water passage hole (not shown). This allows the first temperature sensor 11 and the thermostat component 12 to be protected, while the water from the aquarium 2 can enter the protective housing 13 through the water passage hole and come into contact with the thermostat component 12.

[0034] In some embodiments, such as Figure 2 As shown, the temperature control device 21 may include an evaporator 214, a compressor 215, a condenser 216, and a throttle valve 217. The evaporator 214 is located inside the water tank 24. The compressor 215 is connected to the evaporator 214, the condenser 216, and the control board 23. The condenser 216 is connected to the evaporator 214 through the throttle valve 217.

[0035] In some embodiments, the evaporator 214 can be used to evaporate the heat-carrying liquid inside the evaporator 214 to obtain a heat-carrying gas and send it to the compressor 215; the compressor 215 can be used to compress the heat-carrying gas to obtain a compressed heat-carrying gas and send it to the condenser 216; the condenser 216 can be used to cool and condense the compressed heat-carrying gas to obtain a heat-carrying liquid and send it to the throttle valve 217; the throttle valve 217 can be used to throttle and reduce the pressure of the heat-carrying liquid from the condenser 216 and then send it back to the evaporator 214.

[0036] Specifically, the heat transfer liquid inside the evaporator 214 evaporates and absorbs heat, which can be used to absorb heat from the heat transfer medium inside the water tank 24, thereby reducing the temperature of the heat transfer medium. Subsequently, the low-temperature, low-pressure heat transfer gas is sent from the evaporator 214 to the compressor 215, which compresses the low-temperature, low-pressure heat transfer gas into a high-temperature, high-pressure heat transfer gas, providing power for the refrigeration cycle by increasing the pressure and temperature. The high-temperature, high-pressure heat transfer gas is then sent from the compressor 215 to the condenser 216, which cools and condenses the high-temperature, high-pressure heat transfer gas into a heat transfer liquid, thereby releasing heat into the air or sending heat to the water tank 24 to regulate the temperature of the heat transfer medium. The high-pressure heat transfer liquid is sent from the condenser 216 to the throttling valve 217, which throttles and reduces the pressure of the high-pressure heat transfer liquid from the condenser 216 to obtain a low-temperature, low-pressure heat transfer liquid, which is then sent back to the evaporator 214.

[0037] In some embodiments, the temperature control host 20 may further include a wireless module 26 and a display screen 27, both of which are connected to the control board 23. When abnormal temperature information occurs, such as when the water temperature in the fish tank 2 is abnormal, the control board 23 can drive the wireless module 26 to send warning information to external terminal devices, such as users' mobile phones, tablets, and other terminal devices. The display screen 27 can be used to display the real-time temperature information of the water in the fish tank 2.

[0038] In some embodiments, the temperature control unit 20 may further include a power supply 28 for providing electrical power. The water tank 24 may also be provided with a water inlet 240. The temperature control device 21 may further include a fan 218.

[0039] In some embodiments, the protective housing 13 may house a water separation detection detector (not shown). Specifically, the water separation detection detector may be located on the top of the protective housing 13, that is, at the end of the protective housing 13 closest to the water surface. This allows for monitoring of the operating status of the thermostat 10, such as monitoring for a drop in water level or the thermostat 10 detaching from the water.

[0040] The temperature control system 1 for aquarium 2 of this application includes a first temperature sensor 11 and a temperature control component 12 in the water body of aquarium 2. The temperature control component 12 is connected to the water tank 24 via an external water pipe 30. The control board 23 drives the temperature control device 21 to heat or cool the heat transfer medium based on the acquired temperature information. This heat transfer medium flows from the water tank 24 through the external water pipe 30 and the temperature control component 12 back to the temperature control device 21. In this configuration, this application can regulate the temperature of the water body in aquarium 2 by adjusting the temperature of the heat transfer medium, allowing it to circulate between the water tank 24, the external water pipe 30, the temperature control component 12, and the temperature control device 21 without contacting the water body. This solves the problems of pipe blockage and bacterial contamination of the water body in aquarium 2. The heat transfer medium in this application is completely isolated from the water body in aquarium 2, preventing external impurities from entering the device and avoiding contamination of the water body by the heat transfer medium.

[0041] The above description is merely a preferred embodiment of this application. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this application. Furthermore, under the teachings of this application, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this application. Therefore, this application is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this application.
