The embodiments described herein are specific embodiments of the present application and are presented to illustrate the concepts of the present application; the description is illustrative and exemplary in nature and is not to be construed as limiting the embodiments of the application and the scope of the application. In addition to the embodiments described herein, those skilled in the art will be able to employ other technical solutions which are obvious based on the disclosure of the claims and the specification thereof, and these technical solutions include technical solutions which make any obvious replacement or modification of the embodiments described herein.

The drawings in the present specification are schematic views to assist in explaining the concept of the present application, and schematically show the shapes of respective portions and their interrelationships. It should be understood that the drawings are not necessarily to scale, the same reference numerals being used to identify the same elements in the drawings in order to clearly show the structure of the elements of the embodiments of the present application.

Without limitation, the term water as used herein refers broadly to any liquid that may be used for fish farming and should not be construed narrowly as pure water or tap water, etc. to limit the scope and/or application of the present application.

As shown in fig. 1 and 2, which illustrate, without limitation, an aquarium heating rod 1000 comprising: a heating device 2, a sensing device 4, a control device 6, a housing 10,

cables

7, 8, 9; the sensing device 4, formed in a monolithic sheet, comprises a first sensor 401 and a second sensor 402, or at least a first sensor 401, the first sensor 401 being intended to detect the presence of water and the second sensor 402 being intended to detect the temperature; the control device 6 is respectively connected with the heating device 2 and the sensing device 4 and controls the operation of the heating device 2; the heating device 2 is arranged inside the shell 10; in the aquarium 100, the sensor 4 is disposed above the heating device 2, so that once the sensor 4 is pulled out of the water/aquarium 100 by mistake, the control device 6 can determine whether heating needs to be stopped and prompt an alarm according to the water level information (whether the first sensor 401 detects water) and the temperature information. For example, when the first sensor 401 detects that the sensing device 4 is out of the liquid 3 in the aquarium 100, the control device 6 immediately stops the operation of the heating device 2 and gives an alarm, such as a flashing light, a ringing sound, etc., to alert the user that an excessive heating "water-boiled fish" is likely to occur. On the other hand, as the sensing device 4 is positioned at a position higher than the heating device 2, once the water level is lowered to the position that the detection device is exposed out of the water surface, the control device 6 can be timely sent out related detection information at the first time to stop the heating device 2 from working and give an alarm; on the contrary, if the sensing device 4 is arranged at the same height as the heating device 2 or lower than the heating device 2, the early warning and timely warning cannot be realized.

Therefore, without limitation, the sensing device 4 can be fixed to the aquarium 100 at a position higher than the heating device 2 by the first fixing device 5 such as a suction cup, which has a height difference from the heating device 2 of not less than 1mm, and preferably not less than 2 mm.

Furthermore, the sensor device 4 is connected to the controller 6 through a separate cable 8 and the heating device 2 is connected to the controller 6 through a separate cable 9, which on the one hand facilitates maintenance and increases adaptability of the sensor device 4 to different application scenarios, in other words, the sensor device 4 can be either disposed on the surface of the wall of the aquarium through a fixing device 5 such as a suction cup, can be freely placed in the aquarium or the aquarium, can be clamped or embedded on the upper surface of the housing 10 of the aquarium heating rod 1000 or other positions higher than the heating device 2 in the manner shown in fig. 3, and generally speaking, unless otherwise specified, the heating device 2 described in this application refers specifically to the rod core of the heating rod 1000.

Preferably, but not limitatively, the sensor device 4 is packaged as a rectangular sheet with the second sensor 402 located at the distal end, i.e. the left side in fig. 2, and the first sensor 401 located at the proximal end, i.e. the right side in fig. 2, so that the first sensor 401 can quickly and sensitively detect whether the sensor device 4 is out of water for the first time when the sensor device 4 is pulled out of water by mistake.

According to another aspect of the present application, the sensing device 4 integrally packages the first sensor 401 and the second sensor 402 to form a rectangular sheet, which can be formed to be square, oval, circular, or other shapes that are easily embedded in the groove, but the thickness of the rectangular sheet is preferably 0.5mm to 4mm, and the area of the rectangular sheet is not more than 400mm²The thin sheet is made of a PCB board integrating the two sensors, wherein the sensing board required by the first sensor 401 can be made of copper foil of the PCB or a separate metal sheet, and the area of the sensing board is not less than 20mm 2. The outside is poured into a required shape by using materials such as ABS engineering plastics and the like, and the waterproof and protective functions are realized. The benefits of such a monolithic/integrated package include:

(1) the ornamental fish needs to be frequently changed, and many users often forget that the heating rod is changed after being powered off in advance, so that the heating rod is dried. Because the heating rod has large power and small volume, the fish tank is easy to be cracked and exploded, and even a fire disaster is caused. Therefore, a large number of heating rods with the function of water leaving and power off appear on the market. However, the water level detectors are arranged at a certain position inside the heater of the heating rods, and due to the very complicated application scenes of the heating rods, such as collision of fish or improper installation, the postures of the heating rods in the water body are different, and when the water level is not guaranteed to be reduced, the corresponding position of the water level detector is firstly exposed out of the water surface, and if the heating body is firstly exposed out of the water surface, the danger still exists.

This application is external with water/water level detector, can guarantee that detector mounted position obviously is higher than the heating member, and during the water level reduction, the sensor can expose the surface of water at first, guarantees in time to detect the lack of water to can take through heating controller and cut off the heating member power, measure such as compulsory stop heating and acousto-optic warning.

(2) The traditional heating rod with the heating rod probe externally connected with the temperature probe is easy to be dragged out of the water surface due to misoperation of a user or separated from the water surface due to the falling of an evaporation water level because the probe is light and small, so that the heater is heated ceaselessly, and the phenomenon of 'fish filets in hot water' occurs.

The invention integrates temperature measurement and water level detection, and when the sensor leaves the water surface, the heater can sense the water leaving state in time, thereby cutting off the power supply of the heater and giving an alarm to avoid the accident of 'fish filets in hot chili oil'.

(3) The aquarium heating rod according to the embodiment of the application has the advantages that the sensor device which is integrally packaged and is used for detecting water and temperature is connected with the control device through an independent cable, and the heating device is connected with the controller through an independent lead, so that only two independent cables are needed, and the maintenance and the repair are convenient; in contrast, if one cable is used, the risk of failure and the maintenance and replacement cost of the independent multi-core cable are increased, and if three independent cables are used, other problems such as winding are easily caused.

The advantages mentioned in this application are not limitative but should be understood and explained in connection with the technical solutions of the present application.

The water boiling fish water level sensor creatively integrates temperature measurement and water level detection, and when the sensor leaves the water level, the heater can timely sense the water leaving state, so that the power supply of the heater is cut off, an alarm is given, and the accident of 'water boiling fish' is avoided.

As another preference of the embodiment of the present application, without limitation, fig. 3 and 5 show another configuration of the aquarium heating rod 1000 according to the embodiment of the present application. Wherein, the fixing

devices

11A and 11B such as suction cups for fixing the heating rod 1000 should be selected according to the use situation, and for the large heating rod core/heating device 2 with large self-weight, it can be settled and fixed on the bottom of the aquarium 100 by gravity, but for the heating rod 1000 with small volume and weight, at least 1 fixing device is needed on the bottom to prevent it from being dragged or bumped and moved.

As shown in fig. 3 and 5, the sensor device 4 integrated with the sensor 401 and/or the temperature sensor 402 is formed as a rectangular thin sheet and is clamped into a groove 12 formed on the surface of the housing 10 of the heating rod 1000 by a fixing pin 13, wherein the groove 12 is provided on the upper surface of the housing 10 on the right side of the heating device 2 such that, on the one hand, the height thereof is at least 0.5mm higher than the heating device 2, preferably 2mm or more higher than the same, and, on the other hand, since it is closer to the cable 8 and the cable 9, it detects a state of absence of water prior to the heating device 2 and a dangerous state of leaving water earlier when leaving water due to dragging.

Further, a step structure 1202 is disposed in the groove 12 to prevent the direct adhesion of the detection device 4 to the surface of the housing 10 from affecting the contact between the bottom surface of the detection device 4 and water and thus affecting the detection accuracy and sensitivity thereof, and a water leakage structure/hollow-out structure 1201 is further disposed on the bottom surface and/or the side surface (i.e., the portion of the housing 10 forming the groove) of the groove 12 to make the bottom surface of the detection device 4 sufficiently contact with liquid/water of different sources as much as possible, thereby increasing the sensitivity of the detection device 4, and wherein the height of the step structure 1202 is greater than or equal to 1mm, and preferably greater than or equal to 2mm, so that at least a gap of 1-2mm is formed between the bottom surface of the detection device 4 and the upper surface of the housing 10 to prevent water from residing by capillary action.

More importantly, the aquarium heating rod according to the embodiment of the application has the advantages that due to the adoption of the integrated sensing device 4 which is packaged integrally and the arrangement of the proper fixing structure at the heating device 2, the requirement of a supplementary scene for heating aquarium tanks with different shapes or different structures can be met, for example, for an aquarium with a smooth inner peripheral wall, the sensing device can be arranged on the surface of the peripheral wall of the aquarium through fixing pieces such as suckers according to the actual requirement of water depth; however, for a fish bowl such as a round goldfish bowl, the fixing structure (the groove 12) can be used to fix the sensing device 4 and the heating device 2 together, so as to prevent the sensing device 4 from being moved freely due to small volume and light weight.

In order to prevent water from residing in the grooves 12 and/or the hollow structures 1201 due to capillary effect, the hollow structures 1201 may be formed as a plurality of strip-shaped hollow strip-shaped through holes as shown in fig. 5 or through hole structures with other shapes, as long as it can facilitate the detection device 4 to detect water on the lower surface thereof, which meets the spirit and gist of the present application, in order to increase the water leakage and water guiding effect of the hollow structures 1201, the hollow area of the hollow structures should be greater than or equal to 30% of the bottom area of the sensing device, and the width of each independent hollow strip should be greater than or equal to 1mm and preferably greater than or equal to 2mm, so as to ensure that liquid such as water can smoothly flow through the hollow structures 1201 and be detected by the sensing device 4.

Preferably, under the action of the step structure 1202, since the thickness of the sheet of the detection device 4 is preferably 0.3mm to 4mm, in order to reduce the contact of the detection device with other substances except water and increase the water contact area of the detection device 4, the upper surface of the detection device 4 is preferably higher than the upper surface of the surrounding housing 10 by 0.5mm or more, and preferably higher than the upper surface of the surrounding housing 10 by 1mm or more, and further preferably higher than the upper surface of the entire housing 10 by 1mm or more, so as to prevent the water forming water film from staying on or covering the surface of the detection structure 4 by surface tension to cause misjudgment of water. Further, the surface of the detecting means 4 formed as a thin sheet is formed to be hydrophobic to prevent the detection of remaining or staying water, and alternatively, it is also possible to adopt a structure in which the detecting means 4 is obliquely installed (not shown) to be inclined with respect to the surface of the housing to prevent the staying water. The hydrophobicity may be obtained by a surface treatment process such as polishing or coating or by directly manufacturing the outer surface of the detecting unit 4 using a hydrophobic material. It should be particularly noted that the above-mentioned protrusion type mounting, hydrophobic treatment, and inclined type mounting can be used in combination, as long as they can make the sensing device 4 detect the presence of water as sensitively as possible and reduce the false alarm rate, which belongs to the spirit and gist of the present application.

Alternatively, in order to enhance the fixing of the detecting device 4, a fixing member 13 formed in a rectangular, trapezoidal or cylindrical shape may be additionally provided so that the detecting device 4 is properly fixed in the groove 12 by the step and the fixing member 13.

Fig. 4 shows one of the constituents of the water sensor 401 according to one of the embodiments of the present application, wherein the chip U1, the capacitors C1, C2, C3, the resistor R1, and the sensing piece J1 form a water level monitoring circuit to realize the detection of water/water level by the sensor 401. When the liquid level covers the integrated sensor 4, the U1 detects that the capacitance value of a TCH pin is larger than that of the C3 through the sensing piece J1, and the OUT pin of the U1 outputs effective (high level); when the liquid level is lower than the detection plate of the integrated sensor 4, and the capacitance value of the TCH pin is detected to be smaller than the CREF reference capacitance value by the U1, the output of the OUT pin of the U1 is invalid (low level). U1 can be selected from water level detection chips of JMAWS01, SC01A, SC01, XW01D, APS0141, etc. U2 is a temperature measuring sensor, and U2 and R2 form a temperature measuring circuit. U2 can select conventional temperature measurement technology such as thermistor or semiconductor temperature measurement chip, JP1 is the interface of integrated sensor and MCU; a large-area copper foil is used for manufacturing the induction sheet J1, and a USB interface shown in figure 2 is welded in JP 1.

It is further preferred that the end of said recess 12 close to the cable 9 may be provided with a wire groove 14 so that the cable 8 for linking the detection means 4 and the control means 6 may be embedded therein to prevent bending or damage of the cable from affecting the detection of the sensing means 4.

Furthermore, although the embodiment of the present application shows the integrated detecting means 4, it should be understood that a sensor for detecting temperature may be separately provided at other positions inside or outside the housing 10, and the detecting means 4 is only used for detecting the presence of water (detecting water level), such a heating rod 1000 capable of preventing the boiled fish from being dried belongs to the variation of the embodiment of the present application, without departing from the spirit and gist of the present application.

As shown in fig. 6, when the heating rod 1000 according to the embodiment of the present application is in operation, the control device 6 makes a judgment based on information detected by the water level sensor 401 (first sensor) and the temperature sensor 402 (second sensor), and performs heating if and only if water can be detected and the temperature is not higher than a threshold value; the heating is stopped, the power is cut off and an alarm is given whether no water is detected or overheating is detected, so that double safety protection is realized.
