Description

Technical Field

[0001] This utility model relates to the field of gas water heater technology, and in particular to a gas water heater electrical connection structure and a gas water heater. Background Technology

[0002] Existing gas water heaters typically use either batteries or AC power via a plug-in socket. For battery-powered water heaters, the limited battery capacity necessitates battery replacement after a period of use, and battery levels are difficult to monitor. If the battery runs out and the user hasn't purchased replacements, the water heater becomes unusable, severely impacting usability and reducing user experience. As for AC-powered water heaters, the plug extends from inside the unit via a wire. Regardless of whether the water heater is in use, the wire and plug are constantly exposed, making them susceptible to aging or accidental damage from the external environment. This also affects the normal operation of the water heater and reduces user experience. Utility Model Content

Compared with the power supply method of leading the wires and plugs out of the shell to achieve AC power supply, the gas water heater power connection structure of this utility model embodiment only exposes the plug part, while the other parts are built into the shell. Therefore, it can reduce the impact of external environment on the aging or damage of the power connection device, which is conducive to improving the service life of the gas water heater power connection structure.

[0007] According to some embodiments of this utility model, the power supply interface is a TYPE-C interface.

In the axial direction of the power receiving device, the distance between the first guide surface and the outer peripheral wall of the power receiving device gradually increases along the direction away from the limiting portion, and the distance between the second guide surface and the outer peripheral wall of the power receiving device gradually decreases along the direction away from the limiting portion.

[0010] According to some embodiments of the present invention, the snap-fit ​​portion is provided with a relief hole arranged radially along the power connection device, and the snap-fit ​​portion can deform toward the relief hole when subjected to pressure.

[0011] According to some embodiments of the present invention, the first guide surface is provided with at least two abutting portions arranged sequentially along the axial direction of the power connection device, one of which abuts against the inner periphery of the mounting hole.

[0012] According to some embodiments of the present invention, a flexible gasket is provided on the outer periphery of the power connection device, and the flexible gasket is sandwiched between the limiting part and the outer periphery of the mounting hole.

[0013] According to some embodiments of the present invention, the flexible gasket is rotatably connected to a protective cover, the protective cover being able to rotate relative to the flexible gasket to approach or move away from the power receiving device, and a protective plug adapted to the power supply interface is provided on one side surface of the protective cover; when the protective cover rotates relative to the flexible gasket to approach the power receiving device, the protective cover can cover the power receiving device, and the protective plug is embedded in the power supply interface.

[0014] According to some embodiments of the present invention, the protective cover is rotatably connected to the flexible gasket via a flexible connector. The flexible connector has a groove on its surface near the power supply interface. When the protective cover rotates relative to the flexible gasket, the flexible connector can bend and deform at the groove.

[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0034] Reference Figures 1 to 6This utility model provides an embodiment of a gas water heater electrical connection structure, including a housing 100 and an electrical connection device 200. The housing 100 has a mounting hole 110, and an electrical control device for controlling the operation of the gas water heater is installed inside the housing 100. The electrical connection device 200 is installed in the mounting hole 110 and has an electrical connection terminal 210 located inside the housing 100. The electrical connection terminal 210 is electrically connected to the electrical control device, and a power supply interface 220 for supplying power to the electrical connection terminal 210 is provided on the outer surface of the electrical connection device 200.

[0035] By adopting the gas water heater power connection structure of this utility model embodiment, the power supply interface 220 can be used to directly supply power to the electrical control device of the gas water heater, thereby controlling the operation of the gas water heater. Compared with the battery power supply method, the power connection device 200 is less likely to cause the gas water heater to malfunction due to insufficient power. Compared with the power supply method of leading the wire 280 and plug out from the housing 100 to realize AC power supply, the gas water heater power connection structure of this utility model embodiment only exposes the plug part, while the other parts are built into the housing 100. Therefore, it can reduce the impact of the external environment on the aging or damage of the power connection device 200, which is conducive to improving the service life of the gas water heater power connection structure.

[0036] In some embodiments, a battery electrically connected to the electronic control device may be provided inside the housing 100. When the user does not use the power supply interface 220, the electronic control device can be powered by the battery. When the user uses the power supply interface 220, the electrical connection between the battery and the electronic control device can be disconnected. Thus, the battery can be used as a backup. When the power supply device is damaged or cannot be used, the gas water heater can be powered by the battery, thereby ensuring the normal use of the gas water heater.

[0037] Understandably, referring to Figures 1 to 6 A wire 280 is provided between the power terminal 210 located inside the housing 100 and the power receiving device 200, that is, the power receiving device 200 and the power terminal 210 are electrically connected through the wire 280.

[0038] Reference Figures 1 to 7 In some embodiments, the power supply interface 220 is a TYPE-C interface.

[0039] In the above structure, by setting the power supply interface 220 as a TYPE-C interface, users can plug the TYPE-C connector into the power supply interface 220 to supply power to the gas water heater. The TYPE-C connector is common in daily life, so it can be convenient for users to use and improve the convenience of using the gas water heater.

[0040] It is understood that the power supply interface 220 can be set as a TYPE-C interface, or it can be set as a USB interface or other interfaces. This utility model does not make any specific limitation on this.

[0041] Reference Figures 1 to 7 In some embodiments, the outer end of the power receiving device 200 has a limiting portion 230 extending radially outward along the mounting hole 110. The outer peripheral wall of the power receiving device 200 is provided with two outwardly protruding snap-fit ​​portions 240. The two snap-fit ​​portions 240 are correspondingly disposed on opposite sides of the power receiving device 200. The snap-fit ​​portions 240 are at least partially located inside the housing 100 and abut against the inner periphery of the mounting hole 110. The snap-fit ​​portions 240 and the limiting portion 230 cooperate to clamp the periphery of the mounting hole 110.

[0042] In the above structure, by providing a limiting part 230 and a locking part 240, the limiting part 230 can abut against the outer periphery of the mounting hole 110, thereby preventing the power receiving device 200 from coming out of the mounting hole 110 into the housing 100, that is, preventing the power receiving device 200 from completely falling into the housing 100 through the mounting hole 110. The locking part 240 abuts against the inner periphery of the mounting hole 110, thereby preventing the power receiving device 200 from coming out of the housing 100 through the mounting hole 110, that is, preventing the power receiving device 200 from coming out of the housing 100 through the mounting hole 110. Thus, the limiting part 230 and the locking part 240 can cooperate with each other to limit the installation of the power receiving device 200, making the installation of the power receiving device 200 more stable.

[0043] Reference Figures 5 to 7 In some embodiments, in order to position and install the power receiving device 200, the cross-section of the power receiving device 200 can be set to be non-circular, and the mounting hole 110 can be designed to fit the shape of the power receiving device 200. The cross-sectional shape of the power receiving device 200 can be set to elliptical, rectangular, or other shapes, and this utility model does not specifically limit it.

[0044] Reference Figures 3 to 7 In some embodiments, the snap-fit ​​portion 240 has a first guide surface 241 and a second guide surface 242. The first guide surface 241 abuts against the inner periphery of the mounting hole 110, and the second guide surface 242 is connected to the first guide surface 241 and located on the side of the first guide surface 241 away from the limiting portion 230. In the axial direction of the power receiving device 200, the distance between the first guide surface 241 and the outer peripheral wall of the power receiving device 200 gradually increases along the direction away from the limiting portion 230, and the distance between the second guide surface 242 and the outer peripheral wall of the power receiving device 200 gradually decreases along the direction away from the limiting portion 230.

[0045] By adopting the above structure, the second guide surface 242 can guide the power connection device 200 from the outside of the housing 100 into the mounting hole 110. During this process, the snap-fit ​​portion 240 can deform and retract inward so that the guide portion can be embedded in the mounting hole 110. When the power connection device 200 is installed in place, the snap-fit ​​portion 240 can deform outward, so that the first guide surface 241 can abut against the inner periphery of the mounting hole 110 and cooperate with the limiting portion 230 to clamp the periphery of the mounting hole 110. In addition, the first guide surface 241 can also guide the power connection device 200 from the mounting hole 110 to the outside of the housing 100 when it is necessary to remove the power connection device 200, thereby facilitating disassembly, repair or replacement when the power connection device 200 is damaged.

[0046] It is understood that the snap-fit ​​part 240 and the power receiving device 200 are integrally formed. The snap-fit ​​part 240 and the power receiving device 200 can be integrally formed plastic parts or plastic parts, and this utility model does not make specific limitations in this regard.

[0047] It is understood that the first guide surface 241 and the second guide surface 242 can be guide slopes or curved surfaces, and this utility model does not specifically limit them.

[0048] Reference Figures 3 to 7 In some embodiments, the snap-fit ​​portion 240 has a relief hole 243 arranged radially along the power connection device 200, and the snap-fit ​​portion 240 can deform into the relief hole 243 when under pressure.

[0049] By adopting the above structure, during the installation or disassembly of the power connection device 200, the snap-fit ​​portion 240 will deform inward when squeezed by the inner wall of the mounting hole 110. The provision of the clearance hole 243 can provide deformation space when the snap-fit ​​portion 240 is under pressure, thereby reducing the pressure required for the snap-fit ​​portion 240 to deform, thus making the installation and disassembly of the power connection device 200 easier and less strenuous, and facilitating the installation and disassembly of the power connection device 200.

[0050] Reference Figures 3 to 7 In some embodiments, the first guide surface 241 is provided with at least two abutment portions 244 arranged sequentially along the axial direction of the power connection device 200, one of which abutment portion 244 can abut against the inner periphery of the mounting hole 110.

[0051] In the above structure, each abutment portion 244 is arranged sequentially along the axial direction of the power connection device 200. Therefore, along the direction away from the limiting portion 230, the distance between each abutment portion 244 and the limiting portion 230 gradually increases, thereby enabling the power connection device 200 to adapt to housings 100 of different thicknesses. When facing housings 100 of different thicknesses, the corresponding abutment portion 244 can abut against the inner periphery of the mounting hole 110 and cooperate with the limiting portion 230 to clamp the periphery of the mounting hole 110. This can improve the installation stability of the power connection device 200 and improve the applicability of the power connection device 200.

[0052] Reference Figures 2 to 6 In some embodiments, a flexible gasket 250 is provided around the outer periphery of the power connection device 200, and the flexible gasket 250 is sandwiched between the limiting part 230 and the outer periphery of the mounting hole 110.

[0053] By adopting the above structure, the limiting part 230 can abut against the outer periphery of the mounting hole 110 through the flexible gasket 250 and cooperate with the snap-fit ​​part 240 to clamp the periphery of the mounting hole 110. The setting of the flexible gasket 250 can make the installation between the power connection device 200 and the mounting hole 110 more secure and tight, thereby improving the installation stability of the power connection device 200.

[0054] Reference Figures 1 to 6 In some embodiments, the flexible gasket 250 is rotatably connected to a protective cover 270. The protective cover 270 can rotate relative to the flexible gasket 250 to move closer to or away from the power receiving device 200. A protective plug 271 adapted to the power supply interface 220 is provided on one side surface of the protective cover 270. When the protective cover 270 rotates relative to the flexible gasket 250 to move closer to the power receiving device 200, the protective cover 270 can cover the power receiving device 200, and the protective plug 271 is embedded in the power supply interface 220.

[0055] By adopting the above structure, the protective cover 270 can effectively protect the electrical device 200. When the gas water heater is not in use, the protective cover 270 can be placed on the electrical device 200, and the power supply interface 220 can be sealed by the protective plug 271. This prevents external liquids, dust, insects, etc. from entering the power supply interface 220 and causing damage or aging to the electrical device 200, thus protecting the electrical device 200 and extending its service life. When the gas water heater needs to be used, the protective cover 270 can be rotated away from the electrical device 200, so that the protective plug 271 is removed from the power supply interface 220. The operation is simple and convenient.

[0056] Reference Figures 2 to 6In some embodiments, the protective cover 270 is rotatably connected to the flexible pad 250 via a flexible connector 260. The flexible connector 260 has a groove 261 on its surface near the power supply interface 220. When the protective cover 270 rotates relative to the flexible pad 250, the flexible connector 260 can bend and deform at the groove 261.

[0057] By adopting the above structure, the protective cover 270 is connected to the flexible pad 250 via the flexible connector 260, which facilitates the movement of the protective cover 270, increases its degree of freedom of movement, and makes it more convenient for users. Furthermore, by providing a groove 261 for bending deformation on the flexible connector 260, the flexible connector 260 can easily bend at the groove 261 when the protective cover 270 is rotated, and it is less prone to rebound. This prevents the protective cover 270 from rebounding or the protective plug 271 from detaching from the power supply interface 220 during the process of placing the protective cover 270 on the power connection device 200, making the rotation and closing of the protective cover 270 more convenient and effortless. It also improves the connection stability between the protective plug 271 and the power supply interface 220, facilitating the protection of the power connection device 200.

[0058] An embodiment of this utility model also proposes a gas water heater, which is provided with the gas water heater power connection structure of any of the above embodiments.

[0059] In the gas water heater of this utility model embodiment, by adopting the gas water heater power connection structure of any of the above embodiments, the gas water heater can be powered through the power supply interface 220 on the power connection device 200. This abandons the traditional power supply methods of only using batteries or AC power supply through a plug. It can provide timely power to the gas water heater, making it less likely to run out of power. It can also reduce the impact of the external environment on the power connection device 200, which is conducive to ensuring the normal use of the gas water heater and improving the user experience.

[0060] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
