Description

Technical Field

[0001] The utility model belongs to the technical field of aquarium heating rods, and particularly relates to a heating rod with independent control of multiple heating tubes. Background Art

[0002] The working principle of an aquarium heating rod is as follows: The heating rod is placed in an aquarium device, and the heat generated by the energized heating rod is dissipated in the water of the aquarium device, so that the water temperature of the aquarium device rises or is maintained at a constant temperature. At present, most aquarium heating rod products are configured with a single heating tube or multiple heating tubes connected to a single heating control circuit. When one of the heating tubes or the control circuit fails, the heating rod will malfunction, resulting in problems such as the heating rod not heating or heating out of control. For a heating rod with only one heating tube, when the heating tube fails, it will directly lead to the loss of the heating function of the aquarium device, which has a great impact on the temperature of the living organisms and easily causes the living organisms to get sick or die. Therefore, the use of heating rod products with a single heating tube has great limitations. For a heating rod with multiple heating tubes configured to be connected to a single heating control circuit, since multiple heating tubes are simultaneously controlled by a single heating control circuit, the working switches of multiple heating tubes are synchronized. When one of the heating tubes or the heating control circuit fails, multiple heating tubes will be affected simultaneously, and it is also impossible to control one or more heating tubes to heat independently according to the heating needs. The flexibility of heating tube control is low, and flexible regulation of multiple heating modes cannot be achieved. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a heating rod with independent control of multiple heating tubes.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A heating rod with independent control of multiple heating tubes includes an installation housing, a heating circuit board, and multiple groups of heating tubes. The installation housing includes a first area for installing the heating tubes and a second area for installing the heating circuit board. The first area and the second area are spaced apart. Multiple groups of heating tubes are arranged at intervals in the first area, and the heating circuit board is encapsulated in the second area. The heating circuit board is provided with multiple independently controlled heating control circuits, and multiple groups of the heating tubes and multiple heating control circuits are respectively connected in one-to-one correspondence through circuits.

[0006] In the utility model, the heating circuit board is further provided with multiple detection circuits. Multiple detection circuits are respectively connected in one-to-one correspondence through circuits with multiple groups of heating tubes. The detection circuits are connected to the corresponding heating control circuits and feedback detection signals to the heating control circuits that control the corresponding heating tubes to work.

[0007] In the present utility model, a temperature sensor is further included. The temperature sensor is electrically connected to the heating circuit board. The temperature sensor is used to detect the water temperature, and the heating tube is controlled to work according to the temperature signal detected by the temperature sensor.

[0008] In the present utility model, the first interval and the second interval are separated by a partition board. A fixed horizontal board is further provided in the installation housing. The fixed horizontal board is arranged in the first interval and is opposite to the partition board. Both the partition board and the fixed horizontal board are provided with connection holes for fixedly connecting the ends of the heating tubes. The two ends of the heating tube are respectively fixedly installed in the connection hole of the partition board and the connection hole of the fixed horizontal board through a sealed heat insulation ring.

[0009] The beneficial effects of the present utility model are as follows: By configuring multiple groups of heating tubes in the heating rod, and each group of heating tubes is controlled by an independent heating control circuit. When one group of heating tubes fails, the power supply of this group of heating tubes can be cut off through the heating control circuit connected to it, so that this group of heating tubes is powered off, while other heating tubes can heat normally, thus avoiding the problem that the failure of one group of heating tubes affects all heating tubes; The heating rod can set multiple different heating modes according to different heating requirements, control multiple groups of heating tubes to work simultaneously or take turns to heat, and realize the flexible regulation of multiple heating modes; At the same time, because the number of heating tubes increases, the heating surface area increases, and the heating power is dispersed among multiple groups of heating tubes, the power density is reduced; Therefore, in the same temperature control process, multiple groups of heating tubes work together, and the surface temperature of a single group of heating tubes decreases, which can reduce the scale deposition on the surface of the heating tubes and extend the service life of the heating tubes.

[0020] Such as Figures 1 to 7As shown, this embodiment discloses a heating rod with independent control of multiple heating tubes, which includes an installation housing 1, a heating circuit board 2, and multiple groups of heating tubes 3. The installation housing 1 includes a first section 11 for installing the heating tubes 3 and a second section 12 for installing the heating circuit board 2. The first section 11 and the second section 12 are spaced apart. Multiple groups of heating tubes 3 are arranged at intervals and installed in the first section 11, and the heating circuit board 2 is encapsulated in the second section 12. The heating circuit board 2 is provided with multiple independently controlled heating control circuits 21, and multiple groups of heating tubes 3 and multiple heating control circuits 21 are respectively connected in one-to-one correspondence through circuits. In this embodiment, by configuring multiple groups of heating tubes 3 in the heating rod, and each group of heating tubes 3 is controlled by an independent heating control circuit 21. When a certain group of heating tubes 3 fails, the working power supply of this group of heating tubes 3 can be cut off through the heating control circuit 21 connected to it, so that this group of heating tubes 3 is powered off, while other heating tubes 3 can still heat normally, thus avoiding the problem that the failure of one group of heating tubes 3 affects all heating tubes 3. Since the heating tubes 3 in this embodiment are connected by independent heating control circuits 21, the heating rod can set multiple different heating modes according to different heating requirements, control multiple groups of heating tubes 3 to work simultaneously or take turns to heat, and realize flexible regulation of multiple heating modes. At the same time, because the number of heating tubes 3 increases, the heating surface area increases, and the heating power is dispersed among multiple groups of heating tubes 3, the power density decreases. Therefore, during the same temperature control process, multiple groups of heating tubes 3 work together, and the surface temperature of a single group of heating tubes 3 decreases, which can reduce the scale deposition on the surface of the heating tubes 3 and extend the service life of the heating tubes 3.

[0021] As a preferred embodiment, the heating circuit board 2 is further provided with a plurality of detection circuits 22. The plurality of detection circuits 22 are respectively connected to a plurality of groups of heating tubes 3 in a one-to-one correspondence through circuits. The detection circuits 22 are connected to the corresponding heating control circuits 21, and feedback detection signals to the heating control circuits 21 that control the operation of the corresponding heating tubes 3. The detection circuits 22 are used to detect whether the heating tubes 3 are faulty. When the detection circuit 22 detects that one of the groups of heating tubes 3 is faulty, the detection circuit 22 will send a fault signal to the corresponding heating control circuit 21 to cut off its working power supply, so that the heating tube 3 is powered off, while the other heating tubes 3 can heat normally. Specifically, the detection circuit 22 is a current detection circuit 22. The heating control circuit 21, the detection circuit 22, and the heating tube 3 are connected in series. The detection circuit 22 monitors the working current of the heating tube 3 in real time. When the detection circuit 22 detects that the current of the heating tube 3 is abnormal, it is determined that the group of heating tubes 3 has a leakage, short circuit, or open circuit. The detection circuit 22 feeds back the detection signal to the corresponding heating control circuit 21, thereby controlling the faulty heating tube 3 to cut off the working power supply, thus ensuring the safety of the heating rod during operation. Specifically, the detection circuit 22 can calculate the normal current of the heating tube 3 based on the working power input by the heating control circuit 21 and the resistance of the heating tube 3. The detection circuit 22 compares the actual current actually detected with the normal current. If the difference between the actual current and the normal current is too large, it is determined that the heating tube 3 is faulty; otherwise, the heating tube 3 is normal.

[0022] As a preferred embodiment, the heating rod further includes a temperature sensor 4. The temperature sensor 4 is electrically connected to the heating circuit board 2. The temperature sensor 4 is used to detect the water temperature of the aquarium equipment, and controls the operation of the heating tube 3 through the temperature signal detected by the temperature sensor 4. The working mode of the heating rod is set as follows: before reaching the set temperature, all the heating tubes 3 heat simultaneously; after reaching the set temperature, a timed rotation heating mechanism can be adopted to maintain the temperature. When the heating tubes 3 rotate and heat, the non-working heating tubes 3 are in a cooling state. Therefore, the working time of each heating tube 3 is shortened, effectively reducing the energy consumption of the heating rod and extending the service life of the heating tube 3. For example, in this embodiment, the heating tube 3 is provided with four groups. When the water temperature in the aquarium equipment is lower than the set temperature, the four groups of heating tubes 3 heat simultaneously to quickly raise the water temperature to the set temperature; when the water temperature reaches the set temperature, a timed rotation heating mechanism is adopted to maintain the temperature. The specific method can be:

[0023] As Figure 4 shown, each time a group of heating tubes 3 is set to heat and maintain the temperature, and the other heating tubes 3 do not work. After each group of heating tubes 3 heats for a specified time, the next heating tube 3 is switched to heat and work, and the other heating tubes 3 do not work, and so on for timed rotation heating;

[0024] As Figure 5As shown in the figure, each time two groups of heating tubes 3 are set to heat and maintain the temperature, and the remaining heating tubes 3 do not work. After the two groups of heating tubes 3 have heated and worked for a specified time, another two groups of heating tubes 3 are switched to heat and work, and the remaining heating tubes 3 do not work. By analogy, heating is carried out in a timed and alternating manner;

[0025] As Figure 6 shown in the figure, each time three groups of heating tubes 3 are set to heat and maintain the temperature, and the remaining one group of heating tubes 3 does not work. When the three groups of heating tubes 3 have heated and worked for a specified time, another group of heating tubes 3 is switched to not work, and the remaining three groups of heating tubes 3 are heated and worked for a specified time. By analogy, heating is carried out in a timed and alternating manner;

[0026] As Figure 7 shown in the figure, each time four groups of heating tubes are set to heat and maintain the temperature. When the four groups of heating tubes have heated and worked for a specified time, the four groups of heating tubes stop heating simultaneously. After another specified time, the four groups of heating tubes heat simultaneously again. By analogy, heating is carried out in a timed and alternating manner.

[0027] In addition, the heating tube 3 of this embodiment is also connected with a thyristor, and the heating power of the heating tube is adjusted through the thyristor. And each group of heating tubes is independently connected with a thyristor, so that the heating power of each group of heating tubes can be independently adjusted, with higher flexibility in adjustment and more precise power control. The method of adjusting the heating power of the heating tube through the thyristor can be combined with the above-mentioned timed and alternating heating mechanism to realize the multi-functional control heating of the heating rod.

[0028] As a preferred embodiment, the first interval 11 and the second interval 12 are separated by a partition 13. A fixed horizontal plate 14 is also provided in the installation housing 1. The fixed horizontal plate 14 is arranged in the first interval 11 and is opposite to the partition 13. The partition 13 and the fixed horizontal plate 14 are both provided with connection holes for fixedly connecting the ends of the heating tubes 3. The two ends of the heating tube 3 are respectively fixedly installed in the connection holes of the partition 13 and the fixed horizontal plate 14 through the sealing and heat-insulating rings 5. The sealing and heat-insulating rings 5 play a role in fixing, sealing and waterproofing the ends of the heating tubes 3 and blocking the heat transfer, making the installation of the heating tubes 3 stable, and being able to block the heat generated by the heating tubes 3 from being transferred to the partition 13 and the fixed horizontal plate 14, avoiding the partition 13 and the fixed horizontal plate 14 from being overheated and melted and deformed due to high temperature.

[0029] The above are only the preferred embodiments of the present invention. As long as the technical solutions that achieve the purpose of the present invention by basically the same means fall within the protection scope of the present invention.
