Description

Technical Field

[0001] This utility model relates to the technical field of aquarium heating rods, and in particular to a heating rod with controllable temperature and power. Background Technology

[0002] Existing aquarium heaters have the following problems due to structural limitations:

[0003] 1. The power is rated but there are not many adjustable levels. When the water temperature fails to reach the set temperature within the set time, the power will not be automatically adjusted or an alarm will be triggered to manually adjust the power level.

[0004] 2. Variable frequency heating is achieved by directly controlling the heating rod through a silicon controlled rectifier (SCR). However, SCRs are prone to damage. When damaged, they may fail to heat or become uncontrollable and overheat, resulting in water temperatures that are too low or too high, making it impossible to effectively and stably control the water temperature.

[0005] Therefore, it is necessary to develop a heating rod with controllable temperature and power to solve the above problems. Utility Model Content

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A temperature and power controllable heating rod includes a temperature control device and a heating element, characterized in that it further includes a power module electrically connected to the temperature control device and the heating element;

[0008] The temperature control device includes a main unit and a slave unit that are electrically connected;

[0009] The main unit includes a main control module, as well as a power level adjustment button, a temperature adjustment button, and an adjustable heating module electrically connected to the main control module. The heating element is electrically connected to the power supply module through the adjustable heating module.

[0010] The adjustable heating module is used to control the heating element to automatically and variable-frequency heat the fish tank according to the maximum heating power set by the power level adjustment button.

[0011] The slave unit is located on the heating element. The slave unit includes a second temperature detection unit, a first temperature detection unit, and a water separation detection unit that are electrically connected to the main control module. The first temperature detection unit and the second temperature detection unit are used to monitor the temperature of the aquarium water in real time.

[0012] It also includes a display module electrically connected to the main control module. The display module includes a current water temperature display unit, a set temperature display unit, a real-time power display unit, a power-off display unit when the water is removed, a current gear display unit, and an abnormal fault display unit.

[0013] Preferably, the adjustable heating module includes a silicon controlled rectifier (SCR), a fuse relay, and a protection relay. The input terminal of the SCR is electrically connected to the power module through the fuse relay, and the output terminal is electrically connected to the heating element. The input terminal of the protection relay is electrically connected to the power module, and the output terminal is electrically connected to the heating element.

[0014] Preferably, the temperature adjustment buttons include a temperature increase button and a temperature decrease button that are electrically connected to the main control module.

[0015] Preferably, the power level adjustment button includes a power level increase button and a power level decrease button electrically connected to the main control module. The power level adjustment button has three or more power levels, and the power level can be adjusted by using the power level increase button and the power level decrease button.

[0016] Preferably, the temperature control device further includes a power acquisition module electrically connected to the main control module, the other end of which is electrically connected to the output end of the adjustable heating module, and the power acquisition module is used to acquire the power value output by the thyristor in real time.

[0017] Preferably, the temperature control device further includes an alarm that is electrically connected to the main control module.

[0018] Preferably, the alarm is either a buzzer or a flashing light.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, if the water temperature does not reach the set temperature within the set time, an alarm will be triggered to prompt the user to manually increase the power by adjusting the power level, or the power level will be automatically increased until the water temperature reaches the set temperature, thereby ensuring that the water temperature is maintained at the set temperature and achieving energy-saving temperature control.

[0021] 2. A multi-channel mechanism consisting of dual relays and a silicon controlled rectifier (SCR) is used to control the heating element. When the water temperature reaches the set temperature, if the SCR fails and cannot stop working, the safety relay will disconnect, and then the dual relays will switch to work, allowing the heating element to continue heating the water. This achieves effective and stable temperature control for the aquarium and effectively avoids water temperature that is too low or too high due to SCR failure.

[0022] 3. The power level adjustment button has three or more power levels. Each additional level increases the power according to the set requirements. The heating power is set by adjusting the power level through the power level adjustment button, which is more convenient than existing technologies. Attached Figure Description

Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0030] like Figure 1-2 As shown, a temperature and power controllable 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.

[0031] The temperature control device 1 includes a main unit 100 and a slave unit 200 that are electrically connected;

[0032] The main unit 100 includes a main control module 4, a power level adjustment button 5, a temperature adjustment button 6 and an adjustable heating module 8 electrically connected to the main control module 4, and the heating element 2 is electrically connected to the power module 3 through the adjustable heating module 8.

[0033] The adjustable heating module 8 is used to control the heating element 2 to automatically perform frequency conversion heating on the fish tank according to the maximum heating power set by the power level adjustment button 5.

[0034] The slave unit 200 is disposed on the heating element 2. The slave unit 200 includes a second temperature detection unit 9, a first temperature detection unit 7 and a water separation detection unit 10 that are electrically connected to the main control module 4. The second temperature detection unit 9 and the first temperature detection unit 7 are used to monitor the temperature of the aquarium water in real time.

[0035] It also includes a display module 11 electrically connected to the main control module 4. 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 power-off display unit 114 when the water is removed, a current gear display unit 115, and an abnormal fault display unit 116.

[0036] In this embodiment, the user first sets the maximum heating power using the power adjustment button 5 according to the size of the fish tank or the amount of water, and sets the required water temperature value for the fish tank using the temperature adjustment button 6. Then, under the action of the main control module 4, the adjustable heating module 8 controls the heating element 2 to automatically perform frequency conversion heating on the fish tank according to the set maximum heating power, so that the water temperature in the fish tank is maintained at the set temperature.

[0037] 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 means 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 means that one of the temperature detection units is damaged. At this time, the abnormal fault display unit 116 displays and alarms, thereby enabling accurate detection of water temperature.

[0038] In addition, in this embodiment, when the water temperature in the fish tank needs to be heated to 28 degrees, the power is set to 100W. If 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 the power level needs to be increased manually by pressing the power level adjustment button 5, or the power level can be automatically adjusted until the water temperature reaches the set temperature value within the set time. This achieves high-precision energy-saving temperature control.

[0039] Furthermore, such as Figure 1 As shown, the adjustable heating module 8 includes a silicon controlled rectifier (SCR) 81, a fuse relay 82, and a protection relay 83. The input terminal of the SCR 81 is electrically connected to the power supply module 3 through the fuse relay 82, and the output terminal is electrically connected to the heating element 2. The input terminal of the protection relay 83 is electrically connected to the power supply module 3, and the output terminal is electrically connected to the heating element 2.

[0040] In this embodiment, when the thyristor 81 is functioning normally, if the current water temperature is lower than the set temperature, the protection relay 83 will work first, followed by the fuse relay 82 and the thyristor 81 working simultaneously, causing the heating element 2 to start heating. When the water temperature reaches the set temperature, the thyristor 81 and the fuse relay 82 will disconnect first, followed by the protection relay 83 disconnecting, and the heating element 2 will stop heating, thereby achieving automatic frequency conversion heating.

[0041] In this embodiment, when the thyristor 81 is damaged, there will be a situation where it cannot heat up or overheats out of control. At this time, under the action of the main control module 4, the safety relay 82 is disconnected, and then the dual relays are switched to work, so that the heating element 2 can still work to heat and control the water temperature.

[0042] Compared with existing technologies, the above structure uses a multi-channel mechanism formed by the combination of dual relays and a silicon controlled rectifier 81 to control the heating of the heating element 2. This can effectively and stably control the temperature of the aquarium in the event of a silicon controlled rectifier 81 failure, thus avoiding excessively low or high water temperatures caused by the failure of the silicon controlled rectifier 81.

[0043] Furthermore, such as Figure 1 , 2 As shown, the temperature adjustment button 6 includes a temperature increase button 61 and a temperature decrease button 62 that are electrically connected to the main control module 4.

[0044] In this embodiment, the set temperature can be adjusted by using the temperature increase button 61 and the temperature decrease button 62 according to actual usage requirements, thereby enabling the set temperature to be adjusted by manual button input during initial use or under specific circumstances.

[0045] The temperature increase button 61 and temperature decrease button 62 are controlled as follows: The current water temperature display unit 111 flashes to enter the setting mode, displaying the previous temperature setting value. Pressing the temperature increase button 61 to increment or pressing the temperature decrease button 62 to decrement adjusts the set temperature. The set temperature can be adjusted in a cyclical manner from 16 to 34 degrees. The set temperature value will be automatically saved after 3 seconds of no button operation.

[0046] Furthermore, such as Figure 1 , 2 As shown, the power level adjustment button 5 includes a power level increase button 51 and a power level decrease button 52 that are electrically connected to the main control module 4. The power level adjustment button 5 has three or more power levels, and the power level can be adjusted by using the power level increase button 51 and the power level decrease button 52.

[0047] In this embodiment, when adjusting the power level, the real-time power display unit 113 and the current level display unit 115 display the previous setting value and flash. Pressing the power level increase button 51 to increment or pressing the power level decrease button 52 to decrement adjusts the power level. The real-time power display unit 113 displays the set power value of the corresponding power level.

[0048] The set power value increases with the power level. 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 of no button operation, the set power value will be automatically saved and the set power value will be exited. The real-time power display unit 113 displays the real-time heating power.

[0049] Furthermore, such as Figure 1 As shown, the temperature control device 1 also includes a power acquisition module 12 electrically connected to the main control module 4. The other end of the power acquisition module 12 is electrically connected to the output end of the adjustable heating module 8. The power acquisition module 12 is used to acquire the power value output in real time by the thyristor 81.

[0050] In this embodiment, since the current collected by the power resistor and the calculation by the power chip will both have deviations, the displayed power will deviate from the actual output power. Therefore, the power acquisition module 12 collects the actual power value output by the thyristor 81 in real time and sends it back to the main control module 4. Then, the main control module 4 compares the actual output power value with the displayed power value and performs calibration and adjustment when a deviation occurs.

[0051] Furthermore, such as Figure 1 As shown, the temperature control device 1 also includes an alarm 13 that is electrically connected to the main control module 4.

[0052] In this embodiment, for example, if the water temperature drops by more than 3 degrees when the set power value is used for full power heating for 3 hours, the abnormal fault display unit 116 will flash, the current water temperature display unit 111 will display the current water temperature, and the alarm 13 will be controlled by the main control module 4 to promptly prompt the user to handle the situation.

[0053] Furthermore, the alarm 13 is either a buzzer or a flashing light.

[0054] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
