Description

Technical Field

[0001] This utility model relates to the field of aquarium supplies technology, specifically to a heating rod with a split-type circuit board. Background Technology

[0002] When keeping tropical fish, a heater is needed in the aquarium to heat the water and ensure the water temperature is suitable for the fish's growth. Existing heaters typically contain a heating element, a temperature sensor, a temperature display board, and a circuit control board. The temperature sensor detects the water temperature and sends the signal to the circuit control board, which then controls whether to maintain or stop the heating element. Currently, the electronic components are generally concentrated together above the heating element, as shown in Chinese Patent Publication No. CN212993871U for aquariums. However, this structure is generally suitable for heaters with lower heating element temperatures. When the heating element temperature is higher, the rising heat can damage the circuit control board, leading to decreased performance and a shorter lifespan. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments: In the embodiments, such as Figure 1 , Figure 2 , Figure 3As shown, a heating rod with a split-type circuit board includes a housing, within which a heating element, a temperature display board 1, and a circuit control board 2 are disposed, and further includes: Heating chamber 3 is located in the middle of the shell and is used to install the heating element. The outer walls on the left and right sides of the heating chamber 3 are provided with a gap 4 between them and the inner wall of the shell. Mounting column 5 is positioned above heating chamber 3 and is used to mount temperature display panel 1; Mounting column 6, located below heating chamber 3, is used to mount circuit control board 2; Temperature control chamber 7 is located below mounting column 6 and is used to install temperature sensors.

[0019] Both mounting posts 5 and 6 are made of plastic. The distance 4 between the outer walls of the left and right sides of the heating chamber 3 and the inner wall of the shell forms a wiring channel. The circuit control board 2 is located below the heating chamber 3 and is fixed by melting mounting post 6 with a soldering iron. The wires connect the circuit control board 2 to the temperature display board 1 through the wiring channel. At the same time, the circuit control board 2 is connected to the temperature sensor in the temperature control chamber 7. When the heating element is heated at high temperature, it will not affect the circuit control board 2, thus ensuring the accuracy and life of the circuit control board 2.

[0020] In the embodiments, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the housing includes a front housing 8, a rear housing 9, and a connecting plate 10. The outer circumferential wall of the front housing 8 has a groove 11. The rear housing 9 has corresponding slots 12 on its surfaces. The connecting plate 10 mates with the groove 11.
