Description

Technical Field

[0001] This utility model belongs to the field of heating rod technology, specifically referring to an adjustable heating rod. Background Technology

[0002] Electric heating rods are tools used to heat solutions and other materials. Because they can meet complex heating tasks with simple heating, they are widely used in various fields.

[0003] However, when existing heating rods are inserted into liquids, the main body of the heating rod is exposed to the air and burns dry, causing the temperature of the heating rod to be too high in some areas, which affects its service life. At the same time, the lack of dry burning overheat protection can easily lead to safety accidents. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model proposes an adjustable heating rod, which effectively solves the problem that when the heating rod is inserted into the liquid, the main body of the heating rod is exposed to the air and burns dry, causing the local temperature of the heating rod to be too high, affecting its service life. At the same time, the lack of dry burning overheat protection can easily lead to safety accidents.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes an adjustable heating rod, including a heating power controller and a safety adjustment structure. The safety adjustment structure is disposed on the heating power controller and includes a lifting heating unit and a protection unit. The lifting heating unit is disposed below the heating power controller and the protection unit is disposed below the lifting heating unit.

[0006] The lifting and heating unit includes a socket, a fixed base, a limiting rod, a lifting base, a motor, a threaded rod, a first heating rod, a second heating rod, and a liquid level monitor. The socket is located at the bottom of the heating power controller. The fixed base is fixedly mounted on the bottom of the heating power controller and electrically connected to it. The limiting rod slides through the fixed base. The lifting base is fixedly mounted at the bottom of the limiting rod. The motor is fixed inside the fixed base. The threaded rod passes through the lifting base and is threadedly mounted on the motor. The first heating rod is fixedly mounted on the fixed base and electrically connected. The second heating rod is fixedly mounted on the fixed base and electrically connected. The liquid level monitor is fixedly mounted on the fixed base and electrically connected.

[0007] Preferably, the protection unit includes a protective shell, a circuit breaker, and a high-temperature monitor. The protective shell is fixedly disposed at the bottom of heating rod one and heating rod two. The circuit breaker is fixedly disposed inside the protective shell and disposed at the bottom of heating rod one and heating rod two respectively. The high-temperature monitor is fixedly disposed above the circuit breaker and electrically connected to it.

[0008] To better achieve the lifting and adjusting effect, the limiting rod can be retracted into the socket, and the lifting seat is raised and lowered below the fixed seat.

[0009] To achieve heating more quickly, the lower part of heating rod one and heating rod two are spirally structured, and heating rod one and heating rod two are electrically connected through a circuit breaker.

[0010] Furthermore, the heating power controller is equipped with a rotary temperature adjustment knob, a power adjustment resistor, and a temperature control circuit board, thereby achieving precise temperature regulation.

[0011] To achieve the effect of monitoring high temperature, the high temperature monitor is set between the spiral positions of heating rod one and heating rod two.

[0012] The beneficial effects of this utility model using the above structure are as follows: The adjustable heating rod proposed in this solution detects the liquid level through a liquid level monitor, controls the motor to drive the screw rod to rotate and push the heating rod one and heating rod two on the motor downward into the liquid. At this time, the liquid level monitor reaches the liquid level. If dry burning or excessive temperature occurs, the high temperature monitor detects the abnormal temperature and controls the circuit breaker to disconnect the circuit between heating rod two and heating rod one, thereby avoiding dry burning and causing safety accidents.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes an adjustable heating rod, including a heating power controller 1 and a safety adjustment structure 2. The safety adjustment structure 2 is disposed on the heating power controller 1. The heating power controller 1 is provided with a rotary temperature adjustment knob, a power adjustment resistor and a temperature control circuit board, thereby realizing precise temperature adjustment. The safety adjustment structure 2 includes a lifting heating unit 3 and a protection unit 4. The lifting heating unit 3 is disposed below the heating power controller 1 and the protection unit 4 is disposed below the lifting heating unit 3.

[0021] The lifting heating unit 3 includes a socket 5, a fixed base 6, a limiting rod 7, a lifting seat 8, a motor 9, a threaded rod 10, a first heating rod 11, a second heating rod 12, and a liquid level monitor 13. The socket 5 is located at the bottom of the heating power controller 1. The fixed base 6 is fixedly installed at the bottom of the heating power controller 1 and electrically connected to it. The limiting rod 7 slides through the fixed base 6. The lifting seat 8 is fixedly installed at the bottom of the limiting rod 7, and the limiting rod 7 can be retracted into the socket 5. The lifting seat 8 is raised and lowered below the fixed base 6. The motor 9 is fixedly installed inside the fixed base 6. The threaded rod 10 is threaded through the lifting seat 8 and fixedly installed on the motor 9. The first heating rod 11 is fixedly installed on the fixed base 6 and electrically connected. The second heating rod 12 is fixedly installed on the fixed base 6 and electrically connected. The first heating rod 11 and the second heating rod 12 have a spiral structure at the bottom. The liquid level monitor 13 is fixedly installed on the fixed base 6 and electrically connected.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the protection unit 4 includes a protective shell 14, a circuit breaker 15, and a high-temperature monitor 16. The protective shell 14 is fixedly installed at the bottom of heating rod 11 and heating rod 2 12. The circuit breaker 15 is fixedly installed inside the protective shell 14 and is respectively installed at the bottom of heating rod 11 and heating rod 2 12. Heating rod 11 and heating rod 2 12 are electrically connected through the circuit breaker 15. The high-temperature monitor 16 is fixedly installed above the circuit breaker 15 and electrically connected. The high-temperature monitor 16 is located in the middle of the spiral position of heating rod 11 and heating rod 2 12.

[0023] In practical use, first insert the heating rod 11 and heating rod 12 below the heating power controller 1 into the liquid to be heated. Fix the fixing base 6 below the heating power controller 1 to the container opening. Then connect the heating power controller 1 to the power supply. The liquid level cannot be observed in the container. At this time, the liquid level monitor 13 cannot detect the liquid. At this time, the motor 9 drives the threaded rod 10 to rotate, thereby driving the lifting seat 8 to move downward. At the same time, the upper limit rod 7 of the lifting seat 8 passes through the fixing base 6 to play a limiting role until the liquid level monitor 13 detects the liquid. When the motor 9 stops rotating, it controls the heating rods 11 and 12 below the lifting seat 8 to move downwards. The heating temperature and power are then adjusted via heating rod 11. Heating rods 11 and 12 are connected via circuit breaker 15 for heating. If there is no liquid in the container or the liquid temperature is abnormal, the high-temperature monitor 16 detects an excessively high temperature and controls circuit breaker 15 to disconnect heating rods 11 and 12, thus preventing further heating and potential safety accidents. This is the entire process of using the adjustable heating rods.
