DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] like Figure 1-4 As shown, this embodiment provides an aquarium heating device, including a heating body 1, the outer periphery of the heating body 1 is covered with an inner shell 2, and the outer periphery of the inner shell 2 is covered with an outer shell 3. The upper opening of the outer shell 3 is sealed by a sealing component made of soft rubber material, and the bus 18 passes through the sealing component. In addition, an upper cover 4 is provided on the periphery of the sealing component to fix the sealing component.

[0037] Specifically, the sealing component includes an upper sealing assembly 5, which is sealed at the top of the outer shell 3, and the upper cover 4 is pressed on the periphery of the upper sealing assembly 5 and connected to the outer shell 3, and the upper sealing assembly 5 is pressed and fixed by the upper cover 4. The upper sealing assembly 5 is provided with a wire outlet hole 7, and the bus 18 passes through the wire outlet hole 7. In this embodiment, the top of the upper cover 4 extends a certain width toward the inner circle, so as to be pressed on the upper outer edge of the upper sealing assembly 5, and the inner side surface of the upper cover 4 is screwed and connected with the outer edge of the top of the outer shell 3 by threads, so that the upper cover 4 and the upper sealing assembly 5, and the upper end surface of the outer shell 3 and the upper sealing assembly 5 form a sealed assembly, which plays a waterproof role.

[0038] In this embodiment, the lower end of the upper sealing assembly 5 extends a length to form a cavity structure, the edge of the upper sealing assembly 5 is pressed on the top of the outer shell 3, and the lower end extends a section that fits the inner wall of the outer shell 3, so that the upper sealing assembly 5 and the inner wall of the outer shell 3 also form a sealing relationship, greatly improving the waterproof performance. In addition, a support member 8 is provided in the cavity, and the bus 18 passes through the support member 8. The support member 8 made of hard material serves as a skeleton support to ensure that the upper sealing assembly 5 will not affect the sealing effect due to deformation.

[0039] The sealing assembly further includes a lower sealing sleeve 6, which is located at the periphery of the outer shell 3 and is sealed in the gap between the upper cover 4 and the outer shell 3. A sealing relationship is formed between the lower sealing sleeve 6, the outer shell 3, and the upper cover 4, which plays a waterproof role. The lower sealing sleeve 6 is provided with a protrusion 12, and the upper cover 4 is provided with a groove 13 extending upward from the bottom end. When the upper cover 4 is installed downward, the protrusion 12 is stuck in the groove 13, and the two form a positioning relationship, which plays a positioning role for the lower sealing sleeve 6 and the upper cover 4, and prevents the upper cover 4 from being loosened and affecting the sealing effect.

[0040] The periphery of the inner shell 2 is fixed to the outer shell 3 via a fixing ring 14 .

[0041] The cavity of the outer shell 3 is also provided with a water-off power-off sensor 15, a cavity temperature probe 17 and a heat insulation ring 16. The water-off power-off sensor 15 is close to the inner wall of the outer shell 3 to prevent dry boiling without water. The cavity temperature probe 17 detects the temperature inside the cavity of the outer shell 3. When the temperature reaches a certain value, the power is cut off to ensure safety. A circuit board is installed inside the outer shell 3, and the heat insulation ring 16 can block the heat generated by the heating body 1 from being conducted to the circuit board in the outer shell 3 to a certain extent, thereby preventing the circuit board area on the top of the outer shell 3 from overheating.

[0042] The upper sealing assembly 5 is provided with a pressure relief hole 9. Since the gas inside the cavity will collide when heated, if the control system fails or other reasons cause the heating body to continue to heat, the internal gas pressure will continue to increase. Therefore, the pressure relief hole 9 is provided. When a certain pressure is reached in the cavity, the soft rubber at the pressure relief hole 9 can be pushed open by the pressure to relieve the pressure, thereby improving the safety in an emergency state.

[0043] The upper sealing assembly 5 is provided with a probe hole 10, and a water temperature probe 11 is installed in the probe hole 10, which can more sensitively detect the water temperature of the aquarium. In addition, the bus 18 and the outlet hole 7 are integrally formed; the water temperature probe 11 and the probe hole 10 are integrally formed. In this embodiment, an integral injection molding process is adopted to make the fixing strength of the bus 18 and the water temperature probe 11 higher, and also improve the waterproof effect of the upper sealing assembly 5.

[0044] The bus 18 is equipped with an external control system 19, through which a certain heating temperature is set, and the water temperature probe 11 detects the water temperature of the aquarium. When the water temperature of the aquarium reaches the set temperature, heating is stopped; when the water temperature of the aquarium is lower than the set temperature, heating is started. This cycle repeats.

[0045] The heating device of the present embodiment can form multiple seals on the heating body 1 to prevent the heating body 1 from getting wet, greatly increasing the service life of the heating device and having high safety. In addition, the upper cover 4 and the outer shell 3 are detachable, which facilitates the maintenance of the heating device and reduces the maintenance cost.

For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in this application.
