Description

Technical Field

[0001] This application relates to the field of electricity meter technology, specifically to a waterproof button structure and an electricity meter. Background Technology

[0002] An electricity meter, also known as an energy meter, watt-hour meter, or kilowatt-hour meter, is a specialized instrument used to measure the amount of electrical energy consumed in a circuit. Its core function is to record the cumulative value of electrical energy within a certain period of time, and it is a basic component of electricity metering devices.

[0003] As a core device for measuring electricity consumption, the electricity meter's button waterproof design must meet a specific protection level.

[0004] For example, the patent with publication number CN222546172U discloses a waterproof button structure and an energy meter. This patent completely isolates the tactile switch from the external pressing component by setting a diaphragm inside the sealing sleeve, forming a physical barrier and effectively ensuring the waterproof sealing effect of the tactile switch.

[0005] However, in humid environments or rainy / snowy weather, when the waterproof cover forms a sealed protective space, there is a difference in heat exchange between the internal air and the external environment. At this time, the metal parts of the button area will produce a condensation effect on the air contact surface, and water vapor will condense on the button surface to form tiny water droplets. These tiny water droplets can easily seep into the meter through the button gaps, causing short circuits or button malfunctions.

[0006] Therefore, it is necessary to provide a waterproof button structure and an energy meter to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0008] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a waterproof button structure and an energy meter, which solves the problem that when there is a difference in heat exchange between the inside of the waterproof cover and the external environment, water vapor will condense on the surface of the button to form tiny water droplets. At this time, the tiny water droplets can easily seep into the meter through the gaps in the button, causing short circuits or button malfunctions.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] like Figures 1-2 As shown, this application provides a waterproof button structure and an energy meter, including an energy meter 1, which is mainly installed in an electricity meter box to record the consumption of energy. The energy meter 1 has a display section 10 for displaying electricity consumption information, and a button section 11 is provided at the lower end of the energy meter 1 for operating and setting the parameters of the energy meter 1.

[0038] In order to waterproof the button part 11, a waterproof mechanism 2 is provided at the lower end of the electricity meter 1 at the position of the button part 11. The waterproof mechanism 2 achieves the purpose of waterproofing by covering the button part 11.

[0039] The waterproof mechanism 2 includes a waterproof cover 20 hinged to the lower end of the electricity meter 1, and a slot 22 is provided at the lower end of the electricity meter 1. The size of the slot 22 matches the size of the edge of the waterproof cover 20 so that when the waterproof cover 20 covers the button part 11, it can be fixed by inserting the edge into the slot 22, thereby achieving the effect of covering the button part 11.

[0040] To prevent the formation of tiny water droplets on the button area 11, a water-removing component 21 is provided on one side inside the waterproof cover 20, such as... Figures 1-4 As shown, the dehumidification component 21 prevents water vapor from condensing on the button part 11 inside the waterproof cover 20 by blowing on the surface of the button part 11.

[0041] The dewatering assembly 21 includes a housing 210 fixedly disposed inside one side of the waterproof cover 20, and a mounting bracket 211 fixedly disposed inside the housing 210. A motor 213 is fixedly disposed on one side of the mounting bracket 211. The output end of the motor 213 passes through the mounting bracket 211 and is fixedly connected to a blade 214. Thus, starting the motor 213 can drive the blade 214 to rotate on the mounting bracket 211, thereby generating an air source.

[0042] Furthermore, an air outlet 217 is provided on one side of the cover 210. It should be noted that this air outlet 217 is located when the waterproof cover 20 is closed (see reference). Figure 1 The design is coaxial with the button section 11, so that when the motor 213 starts and drives the blade 214 to rotate and generate air, the air source can be guided to the button section 11 through the air outlet 217 so as to blow away the water droplets that appear on the button section 11.

[0043] When the waterproof cover 20 needs to be defogged, the motor 213 is started to drive the blades 214 to rotate and generate air source, which is then guided to the button part 11 through the air outlet 217, thereby achieving the effect of preventing water droplets from forming on the button part 11 to varying degrees.

[0044] Meanwhile, heat dissipation windows 216 are provided at both ends of the cover 210. These heat dissipation windows 216 are used to exhaust excess hot air inside the waterproof cover 20, thereby achieving the purpose of maintaining a balanced working temperature.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
