[0018] Figure 2 It is an exploded view of the present utility model. [Specific Embodiments]

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings.

[0020] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, the descriptions involving "preferred", "sub-preferred", etc. in the present utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0021] As Figure 1-2 shown, a fish tank heating rod with an external probe includes a control box 1 and a heating box 2 through which water can pass. A heating tube 3 is provided in the heating box 2, and a temperature measuring and water-off induction probe 4 for water temperature detection and power-off induction when off the water extends from the side of the heating box 2 at the upper end. A control circuit board 5 for controlling the heating of the heating tube 3, detecting the water temperature, and powering off after the temperature measuring and water-off induction probe 4 is off the water is provided in the control box 1. The control circuit board 5 in the control box 1 is connected to the heating tube 3 and the temperature measuring and water-off induction probe 4 in the heating box 2 through a power cord. In this case, the control box 1 and the heating box 2 are separately arranged, which can keep the control box 1 away from the fish tank, effectively prevent water vapor from leaking into the control box 1, and play a role in protecting the control circuit board 5 in the control box 1.

[0022] As Figure 1-2 shown, a display component 51 for displaying temperature and fault information, an indicator light for indicating the working state, an alarm for the temperature measuring and water-off induction probe 4 to give an alarm, and a temperature adjustment button component for adjusting the heating temperature are provided on the control circuit board 5; the temperature adjustment button component includes a temperature adjustment button 52 provided on one side of the control circuit board 5 and a silicone button 53 provided on the side of the control box 1 corresponding to the temperature adjustment button 52 for pressing the temperature adjustment button 52. By pressing the silicone button 53, the temperature adjustment button 52 is triggered to input a temperature adjustment signal to the control circuit board 5, and the external temperature adjustment button structure is more convenient to use.

[0023] As Figure 1-2As shown in the figure, the heating box 2 includes an assembly box 21. A locking member 6 is provided inside the assembly box 21. The power cord passes through the heating box 2 and is snap-connected to the locking member 6. The lower end of the temperature measurement and water separation induction probe 4 is snap-fitted on the locking member 6. The heating tube 3 extends out from the lower end of the assembly box 21. An earthing probe connected to the power cord and used to cut off the power supply after contacting the water body is provided inside the assembly box 21. When the water body enters the assembly box 21 and the earthing probe detects the current in the water body after contacting the water body, once the leakage current value in the water body exceeds the rated limit current value, the leakage protector immediately shuts off the output power supply to prevent electric shock danger and improve the use safety performance. On the other hand, the temperature measurement and water separation induction probe 4 extends out and is exposed from the square hole of the assembly box 21 to contact the water body, and can more accurately detect the water temperature information, so as to achieve accurate temperature control; at the same time, the temperature measurement and water separation induction probe 4 detects the water level information. Once it detects that the water level drops and the temperature measurement and water separation induction probe 4 leaves the water, it transmits the water separation information to the control circuit board 5. The control circuit board 5 receives the information, processes it and issues an instruction to immediately shut off the output power supply and stop heating, preventing accidents caused by dry burning due to water shortage. At the same time, the display component 51 displays a fault code, and the alarm buzzer sounds an alarm, which is convenient for customers to handle and maintain in time.

[0024] As Figure 1-2 shown in the figure, a sheath housing 22 is sleeved outside the heating tube 3. The outer shell of the sheath housing 22 is detachably connected to the assembly box 21. Among them, the sheath housing 22 and the assembly box 21 are tightly snap-fitted; a sealing silica gel sleeve 7 that sleeved on the upper end of the heating tube 3 and fixes the upper end of the heating tube 3 inside the assembly box 21 is provided. The upper end of the heating tube 3 is tightly fitted and sealed at the lower end of the assembly box 21 through the sealing silica gel sleeve 7; the assembly box 21 is filled with waterproof glue. An assembly box through hole 211 is provided on the upper side of the assembly box 21, and a detachable box cover 212 covers the assembly box through hole 211. After the sealing silica gel sleeve 7 is installed, the circuit in the accommodation space of the assembly box 21 is fully potted and sealed, and then the assembly box cover 212 is installed to prevent water vapor from penetrating into the interior, so as to better protect the circuit and the probe.

[0025] As Figure 1-2 shown in the figure, a bottom silica gel sleeve 8 that fixes the lower end of the heating tube 3 inside the assembly box 21 is sleeved on the lower end of the heating tube 3 to prevent the heating tube 3 from being damaged during transportation or collision.

[0026] As Figure 1-2 shown in the figure, a sheath housing through hole 221 is provided on the side of the sheath housing 22 to prevent the tortoise's toes from stepping on the heating tube 3 or small fish from swimming in and causing scalding. The densely and evenly distributed small round holes enable the heat of the heating tube 3 to be better dispersed into the water body.

[0027] As Figure 1-2As shown, a silica gel suction cup 9 is sleeved outside the sheath housing 22. The silica gel suction cup 9 is a suction cup with a ring, which can rotate 360 degrees freely to adjust the angle, and the bottom suction and side suction can be changed at will, making the placement more convenient. The rod body has a design of routing the wire upward and lying flat for installation, which is more concise and beautiful. At the same time, the temperature measurement and water-off induction probe 4 always keeps upward, ensuring that once the water level in the fish tank drops, it first passes through the temperature measurement and water-off induction probe 4, triggering the water-off power-off protection alarm to prevent accidents caused by dry burning due to water shortage and improving the safety performance of use.

[0028] The above is only the preferred embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or directly or indirectly applied to other related technical fields, is included in the patent protection scope of the present utility model.
