Description

Technical Field

[0001] The utility model belongs to the technical field of liquid heating rods, and particularly relates to a heating rod capable of sensing posture. Background Art

[0002] At present, the design of preventing dry burning of aquarium heating rod products is mainly achieved by adding a water level sensor. As shown in the Chinese utility model patent with the patent application number 202021558281.X, it discloses a heating rod for aquarium, including a housing. A temperature control chamber and a heating chamber are arranged in the housing, and a water level sensor connected to a temperature control board is installed in the temperature control chamber. The water level sensor is a capacitive water level sensor. When the water level sensor is above the water surface, the load is cut off to stop heating, which is beneficial to protecting the heating rod and ensuring personal safety.

[0003] During the use of the heating rod, due to factors such as the placement angle or the impact of fish, the heating rod may be inclined. The water level sensor in the heating rod is often located on one side of the heating rod. When the heating rod is in an inclined state, the water level sensor may be underwater while part of the heating element is above the water surface. The water level sensor does not sense that part of the heating element has left the water surface, and the heating rod continues to heat and work, resulting in dry burning and damage to the heating rod, and there is also a certain risk to personal safety. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a heating rod capable of sensing posture.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A heating rod capable of sensing posture includes a heating element, a housing, a heating circuit board, a posture sensor and a water level sensor. The heating element is installed on the housing and is electrically connected to the heating circuit board. The water level sensor is fixedly installed on one side of the housing for detecting whether the heating rod is underwater, and the water level sensor is electrically connected to the heating circuit board. The posture sensor is used for detecting the position and posture of the heating rod, and the posture sensor is electrically connected to the heating circuit board.

[0007] In the utility model, the housing includes a first section for installing the heating element and a second section for installing the heating circuit board. The outside of the heating element is fixedly installed naked in the first section, and the heating circuit board is encapsulated in the second section.

[0008] In the utility model, the posture sensor is welded on the heating circuit board and is encapsulated in the second section together with the heating circuit board.

[0009] In the present utility model, a sealing and heat-insulating ring is provided at the connection between the heating element and the housing, and the heat energy generated by the heating element is blocked from being transmitted to the housing through the sealing and heat-insulating ring.

[0010] In the present utility model, the heating circuit board is further connected with a temperature sensor, and the temperature sensor is used to detect the temperature underwater. The heating circuit board controls the operation of the heating element according to the temperature signal detected by the temperature sensor.

[0011] The beneficial effects of the present utility model are as follows: By arranging an attitude sensor in the heating rod, the power supply is cut off when the attitude of the heating rod is incorrect, avoiding the defects of the dry-burning prevention design of the heating rod in the current prior art; when the attitude of the heating rod is correct, it is detected by a water level sensor whether the heating rod is working underwater. When the water level sensor detects that the heating rod is underwater, the heating rod works normally; when the water level sensor detects that the heating rod is exposed above the water surface, the heating circuit board controls the heating element to cut off the power supply and send out an alarm signal outward, enabling the manager to know in time and avoiding the occurrence of damage and accidents caused by the dry burning of the heating element.

[0017] It should be noted that if there are directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...) involved in the embodiments of the present utility model, then the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific attitude (as shown in the drawings). If this specific attitude changes, then the directional indications will also change accordingly.

[0018] In addition, if the descriptions such as "first" or "second" are involved in the embodiments of the present utility model, the descriptions of "first" or "second" etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0019] Such as Figures 1 to 4As shown in the figure, this embodiment discloses a heating rod capable of sensing its posture, which includes a heating element 1, a housing 2, a heating circuit board 3, a posture sensor 4, and a water level sensor 5. The housing 2 includes a first section 21 for installing the heating element 1 and a second section 22 for installing the heating circuit board 3. The outer side of the heating element 1 is fixedly installed naked in the first section 21, and the heating circuit board 3 is encapsulated in the second section 22, so that when the heating rod is in use, the heating circuit board 3 is isolated from water; the water level sensor 5 is fixedly installed on one side of the housing 2 and is used to detect whether the heating rod is underwater. The water level sensor 5 is electrically connected to the heating circuit board 3; the posture sensor 4 is used to detect the position posture of the heating rod, and the posture sensor 4 is electrically connected to the heating circuit board 3. According to the positional relationship between the water level sensor 5 and the heating element 1 in the overall structure of the heating rod, the placement posture that can effectively detect and prevent the heating rod from dry burning due to water separation is determined, and the detection signal value range of the posture sensor 4 in this determined placement posture is pre-loaded into the heating circuit board 3. When the heating rod is heating and working underwater, both the water level sensor 5 and the posture sensor 4 perform detection work and feedback signals to the heating circuit board 3. When the signal data detected by the posture sensor 4 is not within the detection signal value range pre-loaded into the heating circuit board 3, it indicates that the current placement posture of the heating rod is not the placement posture that the water level sensor 5 can effectively detect and prevent the heating rod from dry burning due to water separation. At this time, the heating circuit board 3 controls the heating element 1 to cut off the power and sends out an alarm signal to enable the manager to know in time. The manager can judge whether the water level sensor 5 can effectively detect and prevent the heating rod from dry burning by observing the placement posture of the heating rod. The specific judgment method is as follows: when the heating rod is in the current posture, if the water level drops or the heating rod leaves the water surface during the power-on working state, whether the water level sensor 5 leaves the water before the heating element 1, so as to normally trigger the power-off protection mechanism and prevent the heating rod from dry burning. If the water level sensor 5 cannot effectively detect and prevent the heating rod from dry burning due to water separation, the heating rod is placed in the correct posture to restore normal operation; if the water level sensor 5 can effectively prevent the heating rod from dry burning due to water separation, the detection signal value range of the posture sensor 4 in this placement posture can be loaded into the heating circuit board 3 through an external terminal device such as a controller or a mobile phone as the correct placement posture signal value. When the signal data detected by the posture sensor 4 is within this range the next time, it is judged that the heating rod is in the normal placement posture and continues to work normally without controlling the heating element 1 to cut off the power and sending out an alarm signal, so that the heating rod has an extended function, continuously improves the detection signal value range of the posture sensor 4 in the correct placement posture, and reduces the false alarm situation of the heating rod.When the signal data detected by the attitude sensor 4 is within the range of the detected signal values pre-loaded into the heating circuit board 3, it indicates that the current placement attitude of the heating rod is the placement attitude that the water level sensor 5 can effectively detect to prevent the heating rod from dry burning out of water. At this time, the placement attitude of the heating rod is normal. The water level sensor 5 is used to detect whether the heating rod is working underwater. When the water level sensor 5 detects that the heating rod is underwater, the heating rod works normally; when the water level sensor 5 detects that the heating rod is exposed above the water surface, the heating circuit board 3 controls the heating element 1 to cut off the power and send out an alarm signal outward, enabling the manager to know in time and avoiding damage and accidents caused by the dry burning of the heating element 1.

[0020] As a preferred embodiment, the attitude sensor 4 is welded to the heating circuit board 3 and is encapsulated in the second interval 22 together with the heating circuit board 3, so that both the attitude sensor 4 and the heating circuit board 3 are waterproofed.

[0021] As a preferred embodiment, a sealing and heat-insulating ring 6 is provided at the connection between the heating element 1 and the housing 2. The heat energy generated by the heating element 1 is blocked from being transferred to the housing 2 through the sealing and heat-insulating ring 6, avoiding the housing 2 from melting and deforming due to high-temperature heating.

[0022] As a preferred embodiment, the heating circuit board 3 is further connected to a temperature sensor 7. The temperature sensor 7 is used to detect the temperature underwater, and the heating circuit board 3 controls the operation of the heating element 1 through the temperature signal detected by the temperature sensor 7.

[0023] The above is only the preferred embodiment of the present invention. As long as the technical solutions that achieve the purpose of the present invention by basically the same means fall within the protection scope of the present invention.
