[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Below, the present invention is further described with reference to the accompanying drawings and specific embodiments:

[0034] like Figure 1-3 As shown, a temperature and power controllable fish tank heating rod includes a temperature control device 1 and a heating element 2, and also includes a power supply module 3 electrically connected to the temperature control device 1 and the heating element 2;

[0035] The temperature control device 1 includes a host part 100 and a slave part 200 that are electrically connected;

[0036] The host part 100 includes a main control module 4, and a power gear adjustment button 5, a temperature adjustment button 6, a water separation detection unit 10 and an adjustable heating module 8 electrically connected to the main control module 4. The heating element 2 is electrically connected to the power module 3 through the adjustable heating module 8;

[0037] The slave part 200 is provided on the heating element 2, and includes a slave control module 17 electrically connected to the main control module 4, and a second temperature detection unit 9 and a first temperature detection unit 7 electrically connected to the slave control module 17;

[0038] The adjustable heating module 8 is used to control the heating element 2 to automatically perform variable frequency heating on the fish tank according to the maximum heating power set by the power gear adjustment button 6;

[0039] The second temperature detection unit 9 and the first temperature detection unit 7 are used to monitor the temperature of the fish tank water in real time;

[0040] The host portion 200 also includes a display module 11 electrically connected to the main control module 4. The host portion 100 and the heating element 2 are two independent components. In this embodiment, the temperature control device 1 is composed of a host portion 100 and a slave portion 200, both of which are independently controlled by power supplies. The main control module 4 of the host portion 100 is electrically connected to the slave control module 17 of the slave portion 200. The slave control module 17 can transmit the temperature values ​​detected by the second temperature detection unit 9 and the first temperature detection unit 7, as well as the power value output by the thyristor 81 in real time, to the main control module 4. Compared with the existing technology, the host portion 100 and the heating element 2 are arranged in a separate structure, which is convenient for users to view and set the temperature and power, and is more practical.

[0041] In this embodiment, by setting two temperature detection units, the current water temperature value can be detected by the two temperature detection units. When the temperature difference detected by the two temperature detection units does not exceed the set value, it indicates that the two temperature detection units are functioning normally. At this time, the average value of the two temperature values ​​is taken as the current water temperature; when the temperature difference detected by the two temperature detection units exceeds the set value, it indicates that one of the temperature detection units is damaged. At this time, the abnormal fault display unit 116 displays and alarms, so that the water temperature can be accurately detected.

[0042] In addition, in this embodiment, when the water temperature of the fish tank needs to be heated to 28 degrees, the power set at this time is 100W; when the water temperature detected by the two temperature detection units has not reached 28 degrees within the set time, it proves that the set power is too low; at this time, the abnormal fault display unit 116 displays and alarms, and it is necessary to manually increase the power level through the power level adjustment button 5, or automatically adjust the power level until the water temperature reaches the set temperature value within the set time; thereby achieving high-precision energy-saving temperature control.

[0043] Further, such as Figure 1 、 2 As shown in FIG. 3 , the display module 11 includes a current water temperature display unit 111 , a set temperature display unit 112 , a real-time power display unit 113 , a water-off power-off display unit 114 , a current gear position display unit 115 and an abnormal fault display unit 116 .

[0044] Further, such as Figure 1 As shown, the adjustable heating module 8 includes a thyristor 81, a safety relay 82 and a protection relay 83. The input end of the thyristor 81 is electrically connected to the power module 3 through the safety relay 82, and the output end is electrically connected to the heating element 2. The input end of the protection relay 83 is electrically connected to the power module 3, and the output end is electrically connected to the heating element 2.

[0045] In this embodiment, when the thyristor 81 is normal, when the current water temperature is lower than the set temperature, the protection relay 83 works first, and then the safety relay 82 and the thyristor 81 also work at the same time, so that the heating element 2 starts to heat; when the water temperature reaches the set temperature, the thyristor 81 and the safety relay 82 are disconnected first, and then the protection relay 83 is disconnected, and the heating element 2 stops heating, thereby realizing automatic variable frequency heating.

[0046] In this embodiment, when the thyristor 81 is damaged, the heating may fail or the temperature may overheat. At this time, under the action of the main control module 4, the safety relay 82 is disconnected, and then the double relay operation is switched to enable the heating element 2 to continue to work to heat the water and control the temperature.

[0047] Compared with the existing technology, the above structure controls the heating of the heating element 2 by adopting a multi-way mechanism formed by the combination of a double relay and a thyristor 81. In the event of a failure of the thyristor 81, the temperature of the fish tank can be effectively and stably controlled, thereby avoiding the water temperature being too low or too high due to the failure of the thyristor 81.

[0048] Further, such as Figure 1 、 2 As shown, the temperature adjustment button 6 includes a temperature increase button 61 and a temperature decrease button 62 electrically connected to the main control module 4 .

[0049] In this embodiment, the set temperature can be adjusted by the temperature increase button 61 and the temperature decrease button 62 according to actual use requirements, thereby achieving the adjustment of the set temperature by manual button input during initial use or in specific circumstances.

[0050] The button controls of the temperature increase button 61 and the temperature decrease button 62 are as follows: the current water temperature display unit 111 flashes to enter the setting mode, displaying the last temperature setting value. Press the temperature increase button 61 to increase or press the temperature decrease button 62 to decrease to adjust the set temperature. The adjustment range of the set temperature is 16-34 degrees in a cyclic setting. The set temperature value will be automatically saved after 3 seconds without any button operation.

[0051] Further, such as Figure 1 、 2 As shown in Figure 3, the power gear adjustment button 5 includes a power gear increase button 51 and a power gear decrease button 52 electrically connected to the main control module 4. Three or more power gears are set in the power gear adjustment button 5, and the power gear is adjusted by the power gear increase button 51 and the power gear decrease button 52.

[0052] In this embodiment, when the power gear is adjusted, the real-time power display unit 113 displays and the current gear display unit 115 displays the last set value and flashes. Pressing the power gear increase button 51 to increase or pressing the power gear decrease button 52 to decrease the power gear, the real-time power display unit 113 displays the set power value of the corresponding power gear;

[0053] The set power value increases as the power level increases. For example, there are three power levels: F01, F02, and F03. F01 is 50W. For each additional level, the power increases by 25W, 50W, and 100W, respectively. After 3 seconds without any key operation, the set power value will be automatically saved and exited. The real-time power display unit 113 displays the real-time heating power.

[0054] Further, such as Figure 1As shown, the temperature control device 1 also includes a power collection module 12 electrically connected to the slave control module 17, the other end of the power collection module 12 is electrically connected to the output end of the adjustable heating module 8, and the power collection module 12 is used to collect the power value output by the thyristor 81 in real time.

[0055] In this embodiment, since there will be deviations in the current collected by the power resistor and the calculation of the power chip, resulting in a deviation between the displayed power and the actual output power, the actual power value output by the thyristor 81 is collected in real time by the power collection module 12 and sent back to the slave control module 17, and then sent to the main control module 4 for comparison between the actual output power value and the displayed power value, and calibration adjustment is performed when a deviation occurs.

[0056] Further, such as Figure 1 、 2 As shown in , 3 , the temperature control device 1 further includes an alarm 13 electrically connected to the main control module 4 .

[0057] In this embodiment, for example, when the power value is set to be heated at full power for 3 hours, the water temperature drops by more than 3 degrees. At this time, the abnormal fault display unit 116 flashes, the current water temperature display unit 111 displays the current water temperature, and the alarm 13 is controlled by the main control module 4 to prompt the user to handle it in time.

[0058] Furthermore, the alarm 13 is a buzzer or a flashing light.

[0059] For those skilled in the art, various other corresponding changes and deformations can be made based on the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of this utility model patent.
