Description

Technical Field

[0001] This utility model relates to heating rod technology, and in particular to a heating rod equipped with an adjustable water-sensing probe. Background Technology

[0002] Existing horizontal and vertical heating rods all have their power-off modules fixedly installed on the heating rod body when they are out of water, so they can only be used in a single horizontal or vertical manner.

[0003] Because the power-off module probe of some heating rods is integrated inside the heating rod housing, when the heating rod is placed horizontally, the probe's actual position is lower than the main body of the heating rod due to the fixed installation position of the probe inside the housing. When the heating rod enters the "initial dry-burning state" due to reasons such as water level drop, the main body of the heating rod has been removed from the water, but the probe is still immersed in the water and cannot detect the "water-off" state in time, resulting in the heating rod continuing to dry-burn.

[0004] Therefore, it is necessary to develop a heating rod that can cover both horizontal and vertical usage scenarios. When used horizontally or vertically, the heating rod's power-off module when it leaves the water should be in a position that takes precedence over the heating rod leaving the water. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this invention is to propose a heating rod equipped with an adjustable water-removal sensing probe. When the device is used horizontally or vertically, the water-removal power-off module of the heating rod is positioned in a position that prioritizes the heating rod's detachment from the water.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A heating rod with an adjustable water-free sensing probe includes a housing and a heating element installed inside the housing, and also includes a water-free sensing probe.

[0008] The water separation sensor is mounted on the housing via a displacement assembly, which adjusts the water separation sensor to the top or side of the housing.

[0009] It also includes a control module, wherein the water separation sensor probe is connected to the control module via signal, and the heating element is connected to the control module via power supply;

[0010] The water-off sensing probe is used in conjunction with the control module to establish a power-off function when the device is out of water.

[0011] Preferably, the displacement assembly includes a rotary assembly cavity and a rotary block;

[0012] The rotary assembly cavity is recessed at the intersection of the upper end and the side of the outer shell, forming a receiving position on the outer shell that connects the upper end and the side. The opening of the rotary assembly cavity connects from the upper end of the outer shell to the side.

[0013] The water separation sensor is mounted on the upper part of the rotating block, the lower part of the rotating block is rotatably mounted in the rotating assembly cavity, and the upper part of the rotating block moves relative to the rotating assembly cavity to the upper end or side of the outer shell.

[0014] Preferably, the upper part of the rotating block extends out of the rotating assembly cavity, and the water separation sensor is installed at a position where the rotating block extends beyond the rotating assembly cavity.

[0015] Preferably, the rotating block is a hollow structure, and the water separation sensor probe is installed inside the rotating block;

[0016] The rotating block has a hollow shaft, and the rotating assembly cavity has a wire hole corresponding to the hollow shaft at the rotating shaft mounting position. There is a rotating waterproof sealing structure between the rotating block's rotating shaft and the rotating assembly cavity's rotating shaft mounting position to prevent water from entering the rotating block's rotating shaft and the rotating assembly cavity's rotating shaft mounting position.

[0017] The wire of the water separation sensor is connected to the control module inside the housing via the rotating shaft of the rotating block and the wire hole of the rotating assembly cavity.

[0018] Furthermore, the upper end of the outer casing is provided with a waterproof space, and the control module is located in the waterproof space;

[0019] The waterproof space is connected to the rotating block via the rotating shaft and the wire hole of the rotating assembly cavity.

[0020] Furthermore, it also includes a temperature measurement module, which is installed on one side of the water-free sensing probe;

[0021] The temperature measurement module and the control module are connected by signals, and the temperature measurement module is a non-contact temperature sensor.

[0022] One of the above technical solutions includes the following beneficial effects: This solution adjusts the probe to the top or side using the displacement component, which can cover the horizontal or vertical usage scenarios of the heating rod, so that when the heating rod is used horizontally or vertically, the water-removal power-off module of the heating rod is in a position that takes precedence over the heating rod leaving the water.

[0027] The components include: outer shell 100, heating element 200, displacement assembly 300, rotary assembly cavity 310, rotating shaft mounting position 311, rotating block 320, rotating shaft 321, and control module 400. Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figure 1-2 As shown, a heating rod with an adjustable water-free sensing probe includes a housing 100 and a heating tube 200 installed in the housing 100, and also includes a water-free sensing probe.

[0030] The water-free sensing probe is mounted on the housing 100 via a displacement assembly 300, and the displacement assembly 300 is used to adjust the water-free sensing probe to the top or side of the housing 100.

[0031] It also includes a control module 400, the water separation sensor probe is connected to the control module 400 via signal, and the heating element 200 is connected to the control module 400 via power supply;

[0032] The water-off sensing probe is used in conjunction with the control module 400 to form a water-off power-off function.

[0033] This solution uses displacement component 300 to adjust the probe to the top or side, covering both horizontal and vertical usage scenarios for the heating rod. This ensures that, regardless of whether the heating rod is used horizontally or vertically, the water-removal power-off module is positioned before the heating rod itself leaves the water. The water-removal sensing probe, along with the control module 400, forms the water-removal power-off function; the water-removal sensing probe is a separate liquid level sensor.

[0034] like Figure 2 As shown, the displacement assembly 300 includes a rotary assembly cavity 310 and a rotary block 320;

[0035] The rotary assembly cavity 310 is recessed at the junction of the upper end and the side of the outer shell 100, forming a receiving position on the outer shell that connects the upper end and the side. The opening of the rotary assembly cavity 310 connects from the upper end of the outer shell 100 to the side.

[0036] The water separation sensor is mounted on the upper part of the rotating block 320, the lower part of the rotating block 320 is rotatably mounted on the rotating assembly cavity 310, and the upper part of the rotating block 320 moves relative to the rotating assembly cavity 310 to the upper end or side of the outer shell 100.

[0037] The rotating assembly cavity 310 is a recessed rather than an external protruding structure. The lower part of the rotating block 320 is embedded in the assembly cavity, and only the upper part where the probe is installed is exposed. Whether used horizontally or vertically, when the rotating block 320 is set upward, the overall structure does not increase the radial dimension of the heating rod, avoiding installation inconvenience (such as inability to fit into a narrow corner of the aquarium) or interference caused by the protrusion of the rotating block 320.

[0038] The upper part of the rotating block 320 extends out of the rotating assembly cavity 310, and the water separation sensor is installed at the position where the rotating block 320 extends beyond the rotating assembly cavity 310.

[0039] When the rotating block 320 drives the probe to the top of the housing 100, the extended probe can be higher than the top plane of the heating rod. Even if the heating rod is in shallow water, the probe can be removed from the water first, triggering power off in advance. The distance from the upper part of the rotating block 320 extending out of the rotating assembly cavity 310 is in the range of 0.5cm to 3cm.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the rotating block 320 is a hollow structure, and the water separation sensor is installed inside the rotating block 320;

[0041] The rotating shaft 321 of the rotating block 320 is a hollow shaft, and the rotating shaft mounting position 311 of the rotating assembly cavity 310 is provided with a wire hole corresponding to the hollow shaft. The rotating shaft 321 of the rotating block 320 and the rotating shaft mounting position 311 of the rotating assembly cavity 310 are a rotating waterproof sealing structure to prevent water from entering the rotating shaft of the rotating block 320 and the rotating shaft mounting position of the rotating assembly cavity 310.

[0042] The wire of the water separation sensor is connected to the control module 400 inside the housing 100 via the rotating shaft of the rotating block 320 and the wire hole of the rotating assembly cavity 310.

[0043] The rotating waterproof sealing structure, usually a rotating sealing ring, can fill the gap between the rotating shaft and the mounting position, while allowing the rotating shaft to rotate freely. The seal fits tightly against the outer wall of the rotating shaft and the inner wall of the assembly cavity to form a rotating sealing structure. Even if the heating rod is immersed for a long time, it can prevent water from seeping into the inside of the rotating shaft and the wire hole channel, ensuring the dryness and safety of electrical components from the source.

[0044] The upper part of the outer shell 100 is provided with a waterproof space, and the control module 400 is located in the waterproof space;

[0045] The waterproof space is connected to the rotating block 320 via the rotating shaft of the rotating block 320 and the wire hole of the rotating assembly cavity 310.

[0046] The connection between the waterproof space and the rotating block 320 ensures that the wire transmission path is completely in a waterproof environment, and the wire does not come into contact with external water throughout its entire journey.

[0047] As a supplement to the above technology, a temperature measuring module is also included, which is installed on one side of the water-free sensing probe;

[0048] The temperature measurement module and the control module 400 are connected by a signal, and the temperature measurement module is a non-contact temperature sensor.

[0049] The water level can be detected at the same time as the temperature.

[0050] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
