Description

Technical Field

[0001] This utility model relates to the technical field of heating devices, and more specifically, to a heating device. Background Technology

[0002] A bathroom heater, a common heating device in modern bathrooms, has a thermostat as one of its core components. This thermostat monitors and controls the temperature of the heater's heating element (such as a PTC heater) to ensure safe and efficient operation. Thermostats can be broadly classified into two categories: automatic reset and manual reset. An automatic reset thermostat immediately cuts off the power supply when it detects that the PTC temperature is too high. When the PTC temperature drops to a safe range, it automatically restores the current path, allowing the PTC to reheat. This mechanism simplifies operation to some extent, but in certain environments or situations, automatic reset may lead to frequent starting and stopping of the PTC, affecting the lifespan and safety of the bathroom heater.

[0003] Manual reset thermostats differ from traditional thermostats. While they also cut off power when the PTC temperature is too high, they don't automatically restore the circuit; instead, the user must manually reset them. This design avoids frequent PTC activation, thus protecting both the bathroom heater and the user's safety. However, traditional manual reset thermostats are usually located inside the bathroom heater, requiring the user to disassemble the heater's casing to access the reset button or use a special tool to trigger the reset from the outside. This process is not only complex but also poses certain safety hazards in the humid bathroom environment, reducing the user experience of the bathroom heater.

[0004] As can be seen from the above, current heating devices suffer from the inconvenience of manually resetting the thermostat. Utility Model Content

[0005] The main purpose of this utility model is to provide a heating device to solve the problem that the manual reset thermostat is inconvenient to operate in existing heating devices.

[0006] To achieve the above objectives, according to one aspect of the present invention, a heating device is provided, comprising a housing, a thermostat, and a button structure. The thermostat is disposed inside the housing and has a manual reset button. The button structure is movably disposed on the housing and is disposed opposite to the reset button. The button structure can abut against and drive the reset button to reset or be disposed at an interval from the reset button.

[0007] Furthermore, the outer casing has a hole structure opposite to the reset button. The first end of the button structure is connected to the edge of the hole in the hole structure, and the second end of the button structure either blocks the hole structure or can move through the hole structure to abut against the reset button.

[0008] Furthermore, the first end of the button structure is integrally molded onto the outer casing.

[0009] Furthermore, the button structure is made of elastic material, and the second end of the button structure abuts against the reset button through elastic deformation.

[0010] Furthermore, the heating device also includes a reset component, one end of which is fixed inside the housing, and the other end of which is connected to the second end of the button structure. The reset component provides a driving force for the button structure to move toward the side away from the reset button.

[0011] Furthermore, the interior of the casing has an air duct, and the perforated structure is located on the side of the casing near the air outlet of the air duct.

[0012] Furthermore, the heating device also includes a heating element, which is located inside the air duct. The end of the thermostat away from the button structure passes through the side wall of the air duct and engages with the heating element.

[0013] Furthermore, the heating device also includes a heating element. Along the length of the outer casing, a thermostat is located on one side of the heating element for temperature sensing. A reset button is located on the surface of the thermostat facing away from the heating element. The button structure is located on the side of the thermostat facing away from the heating element.

[0014] Furthermore, the reset button has an extended position and a reset position. When the reset button is in the extended position, there is a first distance between the reset button and the button structure. When the reset button is in the reset position, there is a second distance between the reset button and the button structure. The first distance is smaller than the second distance, and the button structure can drive the reset button to move from the extended position toward the reset position.

[0015] Furthermore, the heating device also includes a bracket and a heating element, which are mounted on the bracket to form a mounting structure, and the mounting structure is located inside the outer casing.

[0016] Applying the technical solution of this utility model, the heating device of this application includes a shell, a thermostat, and a button structure. The thermostat is located inside the shell and has a manual reset button. The button structure is movably mounted on the shell and is arranged opposite to the reset button. The button structure can abut against and drive the reset button to reset or be spaced apart from the reset button.

[0017] As can be seen from the above, the heating device of this application adopts a button structure on the outer shell that is opposite to the reset button of the thermostat. When it is necessary to trigger the manual reset button of the thermostat during use, the reset button can be driven by pressing the button structure to complete the reset action of the thermostat. There is no need to disassemble the outer shell to reset the thermostat or operate the reset button inside the outer shell with tools. The structure of this application is simple to operate and avoids the risk of electric leakage, thus improving the convenience and safety of use. Attached Figure Description

[0034] To address the problem of inconvenient manual reset of the thermostat in existing heating devices, this invention provides a heating device.

[0035] The heating device is a bathroom heater.

[0036] like Figures 1 to 10 As shown, the heating device includes a housing 10, a thermostat 30, and a button structure 20. The thermostat 30 is located inside the housing 10 and has a manual reset button 40. The button structure 20 is movably mounted on the housing 10 and is positioned opposite to the reset button 40. The button structure 20 can abut against the reset button 40 to reset or be spaced apart from the reset button 40.

[0037] In this application, the temperature controller 30 is a manually reset temperature controller 30. To reset the temperature controller 30, the reset button 40 needs to be actively triggered. The temperature controller 30 is reset by using the reset button 40.

[0038] Specifically, the heating device of this application has a button structure 20 on the outer casing 10 that is opposite to the reset button 40 of the thermostat 30. When it is necessary to trigger the manual reset button 40 of the thermostat 30 during use, the reset button 40 can be driven to reset by pressing the button structure 20, thus completing the reset action of the thermostat 30. It is not necessary to disassemble the outer casing 10 to reset the thermostat 30 or to operate the reset button 40 inside the outer casing 10 with tools. The structure of this application is simple to operate and avoids the risk of electric leakage, thus improving the convenience and safety of use.

[0039] In this embodiment, the outer casing 10 has a hole structure 110 that is disposed opposite to the reset button 40. The first end of the button structure 20 is connected to the edge of the hole of the hole structure 110, and the second end of the button structure 20 blocks the hole structure 110 or can move through the hole structure 110 to abut against the reset button 40.

[0040] In this embodiment, the hole structure 110 is configured to provide an installation position for the button structure 20. In this application, the first end of the button structure 20 is connected to the edge of the hole, and the second end of the button structure 20 is formed as a free end, so that the second end of the button structure 20 can move toward the reset button 40 and drive the reset button 40 to trigger it. The cooperative design of the button structure 20 and the hole structure 110 not only ensures the normal operation of the thermostat 30 and simplifies the operation, but also effectively prevents foreign objects from entering the interior, thereby improving the safety and reliability of the heating device.

[0041] Specifically, the hole structure 110 of this application is roughly rectangular opening structure. The button structure 20 is connected to one edge of the hole structure 110, and the button structure 20 is spaced apart from the other three edges of the hole structure 110, so that the button structure 20 can pass through the hole structure 110 to drive the reset button 40. When the button structure 20 is not under force, it can block the hole structure 110, thereby achieving a protective function.

[0042] It is understood that the button structure 20 of this application is generally a rectangular plate structure corresponding to the hole structure 110, so as to cover the hole structure 110 in a conformal manner.

[0043] In this embodiment, the first end of the button structure 20 is integrally formed on the outer casing 10. This integral forming of the outer casing 10 and the button structure 20 helps ensure the installation strength of the button structure 20, thereby improving the overall strength of the heating device and reducing the risk of component loosening or damage due to prolonged use. The overall structure of this application is simple and easy to operate, facilitating rapid triggering of the reset button 40.

[0044] In one specific embodiment of this example, the button structure 20 is made of elastic material, and the second end of the button structure 20 abuts against the reset button 40 through elastic deformation.

[0045] Specifically, the first end of the button structure 20 is integrally formed with the outer shell 10, and the second end of the button structure 20 can undergo elastic deformation so that when pressed by an external force, the second end of the button structure 20 moves toward the reset button 40 and triggers the reset button 40. After the external force is released, the second end of the button structure 20 resets the blocking hole structure 110 under the action of elastic force.

[0046] The reset button 40 can be triggered by the elastic deformation of the button structure 20 itself, or it can be restored to the shielding hole structure 110. This is conducive to further realizing the rapid triggering of the reset button 40. The structure is simple and has high installation strength. No additional structure is required, which helps to improve assembly efficiency.

[0047] In another specific embodiment of this invention, the heating device further includes a reset member, one end of which is fixed inside the housing 10, and the other end of which is connected to the second end of the button structure 20. The reset member provides a driving force for the button structure 20 to move toward the side away from the reset button 40.

[0048] Specifically, the reset element can be a spring. After the button structure 20 is subjected to external force, the second end moves toward the reset button 40. The second end of the button structure 20 drives the reset element to compress. After the second end of the button structure 20 triggers the reset button 40, the external force is released, and the button structure 20 is reset under the action of the reset force of the reset element.

[0049] The reset element in this application helps to ensure that the button structure 20 can switch between abutting the reset button 40 and being spaced apart from the reset button 40, thereby improving the stability of the button structure 20 in use.

[0050] In this embodiment, the interior of the outer casing 10 has an air duct, and the perforation structure 110 is provided on the side of the outer casing 10 near the air outlet of the air duct.

[0051] The air duct is formed inside the outer shell 10 to realize gas flow. The gas enters through the air inlet of the air duct, is heated inside the air duct, and then flows out through the air outlet of the air duct.

[0052] It is understandable that the outer casing 10 has an integrally formed sidewall that forms an air duct. The heating device also includes a heating element 50, which is located inside the air duct. The end of the thermostat 30 away from the button structure 20 passes through the sidewall of the air duct and engages with the heating element 50. This engagement can be either the thermostat 30 directly contacting the heating element 50 to sense its temperature, or a gap forming between the thermostat 30 and the heating element 50, with the thermostat 30 sensing the temperature of the heating element 50 through the gap.

[0053] In this embodiment, the temperature controller 30 is located on the side near the air outlet of the air duct. The temperature controller 30 is configured to work in conjunction with the heating element 50 located inside the air duct, which can more accurately sense the temperature of the air outlet and thus more accurately sense the working status of the heating element 50. The heating element 50 is located inside the air duct on the side near the air outlet to heat the gas facing the air outlet, which helps to improve heating efficiency and ensure the uniformity of gas heating.

[0054] like Figure 5 and Figure 10 As shown, the heating device also includes a heating element 50, and a thermostat 30 is used to sense the temperature of the heating element 50. The heating element 50 is disposed inside the outer casing 10 for heating gas.

[0055] The heating element 50 is a PTC, and it is installed inside the air duct to heat the gas.

[0056] Specifically, along the length of the outer casing 10, the thermostat 30 is disposed on one side of the heating element 50 for temperature sensing, the reset button 40 is disposed on the surface of the thermostat 30 away from the heating element 50, and the button structure 20 is disposed on the side of the thermostat 30 away from the heating element 50.

[0057] The length direction of the outer casing 10 is Figure 1 and Figure 6 The X direction is shown.

[0058] In this embodiment, the button structure 20, the thermostat 30 and the heating element 50 are arranged along the length of the outer shell 10, which makes reasonable use of the internal space of the outer shell 10 and facilitates the triggering of the reset button 40 through the button structure 20, thus improving the convenience of operation.

[0059] In this embodiment, as Figure 5 and Figure 10 As shown, the reset button 40 has an extended position and a reset position. When the thermostat 30 is working normally, the reset button 40 is in the reset position. When the temperature of the heating element 50 is too high, the reset button 40 of the thermostat 30 will extend to the extended position and stop working. At this time, the reset button 40 needs to be triggered to switch the reset button 40 to the reset position, and the thermostat 30 resumes working to sense the temperature of the heating element 50.

[0060] Specifically, such as Figure 10 As shown, when the reset button 40 is in the extended position, there is a first distance between the reset button 40 and the button structure 20; as Figure 5 As shown, when the reset button 40 is in the reset position, there is a second distance between the reset button 40 and the button structure 20. The first distance is smaller than the second distance, and the button structure 20 can drive the reset button 40 to move from the extended position toward the reset position.

[0061] When the temperature of the heating element 50 is too high, causing the reset button 40 to extend to the extended position, this application moves the button pressing structure 20 toward the reset button 40 and drives the reset button 40 to move, thereby driving the reset button 40 to switch from the extended position to the reset position, so that the temperature controller 30 can work again.

[0062] In this embodiment, during the assembly process of the heating device, the heating element and thermostat 30 can be installed first, and then the whole device can be installed inside the outer casing 10, which helps to improve the overall installation efficiency and ensure installation accuracy.

[0063] Specifically, the heating device also includes a bracket, and the heating element 50 and the thermostat 30 are mounted on the bracket to form a mounting structure, which is located inside the outer casing 10.

[0064] In this embodiment, the bracket and the outer shell 10 can be connected by a detachable structure, such as fasteners or snap-fit ​​structures to install the bracket. This application uses a bracket to preposition the heating element 50 and the thermostat 30, which facilitates the positioning and installation of the heating element 50 and the thermostat 30. At the same time, using a bracket inside the outer shell 10 helps to improve the installation strength and stability of the thermostat 30 and the heating element 50.

[0065] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0066] The heating device of this application has a button structure 20 on the outer casing 10 that is opposite to the reset button 40 of the thermostat 30. When it is necessary to trigger the manual reset button 40 of the thermostat 30 during use, the reset button 40 can be driven by pressing the button structure 20 to complete the reset action of the thermostat 30. There is no need to disassemble the outer casing 10 to reset the thermostat 30 or to operate the reset button 40 inside the outer casing 10 with tools. The structure of this application is simple to operate and avoids the risk of leakage, thus improving the convenience and safety of use.

[0067] The button structure 20, the thermostat 30 and the heating element 50 are arranged along the length of the outer casing 10, which makes reasonable use of the internal space of the outer casing 10 and facilitates the triggering of the reset button 40 through the button structure 20, thus improving the convenience of operation.

[0068] The first end of the button structure 20 is integrally formed with the outer shell 10, and the second end of the button structure 20 can undergo elastic deformation. The button structure 20 itself can trigger the reset button 40 or return to the shielding hole structure 110 through its own elastic deformation. This is conducive to quickly triggering the reset button 40, and the structure is simple and has high installation strength. No additional structure is required, which is conducive to improving assembly efficiency.
