[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1: Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a moisture-proof and anti-theft electricity meter, including an electricity meter body 1, a housing 2 on one side of the electricity meter body 1, a ventilation component 3 on one side of the electricity meter body 1, and a protective component 4 at the bottom of the electricity meter body 1.

[0023] The main body 1 of the electricity meter is the core part, used to measure the consumption of electricity and realize basic functions such as measuring, processing and displaying electricity data. The housing 2 protects the main body 1 of the electricity meter, preventing external dust, moisture, foreign objects and other objects from entering the electricity meter. It can also prevent human damage and electricity theft to a certain extent. The ventilation component 3 is used to ventilate the main body 1 of the electricity meter, improve the moisture-proof performance and prevent the accumulation of moisture inside. The protective component 4 is used to protect the cable interface at the bottom of the main body 1 of the electricity meter.

[0024] The ventilation assembly 3 includes multiple sets of vertical slots 31 opened on the inner wall of the electricity meter body 1. A frame 32 is fixed to the inner wall of the electricity meter body 1, and an exhaust fan 33 for exhaust ventilation is fixed to the inner wall of the frame 32.

[0025] The vertical slot 31 provides a channel for air circulation, allowing the airflow driven by the exhaust fan 33 to flow better within the electricity meter body 1, thus facilitating heat dissipation and accelerating moisture removal. The frame 32 is used to fix the exhaust fan 33 and also provides mounting support for the adsorption plate 14. The exhaust fan 33 promotes airflow inside the electricity meter body 1 through its operation, preventing the performance of the electricity meter body 1 from being affected by internal moisture, achieving a moisture-proof effect. When ventilation is needed, the exhaust fan 33 is turned on, allowing air to circulate through the airflow. Figure 2 Air enters through the vertical slot 31 shown and is then exhausted through the exhaust fan 33. The air passes through the interior of the electricity meter body 1, providing ventilation and moisture protection for its interior.

[0026] The protective component 4 includes a protective frame 41 installed at the bottom of the electricity meter body 1. A magnet 42 is fixedly connected to the inner wall of the protective frame 41. An iron block 43 is magnetically connected to one side of the magnet 42, and the top of the iron block 43 is fixedly connected to the bottom of the electricity meter body 1.

[0027] The protective frame 41 is installed at the bottom of the electricity meter body 1 to protect the wire interface at the bottom of the electricity meter body 1. The magnet 42 is connected to the iron block 43 by magnetism, so that the protective frame 41 can be firmly installed at the bottom of the electricity meter body 1, which is convenient for disassembly and installation. The iron block 43 cooperates with the magnet 42 to provide a magnetic connection point, so that the protective frame 41 is stably connected to the bottom of the electricity meter body 1.

[0028] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] Specifically, a pressure sensor body 5 is fixedly connected to the bottom of the electricity meter body 1, and the bottom of the pressure sensor body 5 is inserted into the inner wall of the protective frame 41.

[0030] The pressure sensor body 5 is installed at the bottom of the electricity meter body 1 and can detect pressure changes between the protective frame 41 and the electricity meter body 1. If someone attempts to illegally disassemble the protective frame 41, the pressure will change, and the pressure sensor body 5 can transmit the signal to the alarm light on one side of the electricity meter body 1 to realize the alarm function. It should be noted that the pressure sensor body 5 is based on the same principle as the micro-fusible pressure sensor in the electricity meter with the authorized application number CN202222677637.7 entitled "Anti-theft Electricity Protection". At the same time, the pressure sensor body 5 can transmit the signal to the control circuit inside the electricity meter body 1. The control circuit drives the alarm light and buzzer on one side to realize the audible and visual alarm function.

[0031] Specifically, the bottom of the electricity meter body 1 is fixedly connected to the first vertical plate 6 and the second vertical plate 7, and the protective frame 41 is inserted between the first vertical plate 6 and the second vertical plate 7.

[0032] The first vertical plate 6 and the second vertical plate 7 are inserted into the top of the protective frame 41 to limit the horizontal movement of the protective frame 41, ensuring that the protective frame 41 is installed in place and preventing it from moving horizontally, thereby enhancing the stability of the installation of the protective frame 41.

[0033] Specifically, the bottom of the electricity meter body 1 is fixedly connected to a first horizontal plate 8 and a second horizontal plate 9, and the protective frame 41 is inserted between the first horizontal plate 8 and the second horizontal plate 9.

[0034] The protective frame 41 is inserted between the first horizontal plate 8 and the second horizontal plate 9 to limit the horizontal movement of the protective frame 41, prevent the protective frame 41 from shaking in the horizontal direction, and further fix the position of the protective frame 41.

[0035] Specifically, the inner wall of the protective frame 41 is provided with a through groove 10, and a handle 11 is fixedly connected to the bottom of the protective frame 41.

[0036] The through slot 10 is used to pass cables through, allowing for better wiring of the electricity meter body 1. The handle 11 provides a point of leverage when opening or closing the protective frame 41, making it easy to operate.

[0037] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0038] Specifically, a rain guide plate 12 is fixed to the inner wall of the frame 32, and a rain shield plate 13 is fixed to one side of the frame 32.

[0039] The rain guide plate 12 is tilted downward at 45° to change the direction of rainwater flow and prevent rainwater from directly entering the inside of the electricity meter body 1 through the ventilation opening on one side of the frame 32, which could damage the internal electrical components. The rain shield plate 13 further blocks rainwater from the outside, making it difficult for it to approach the ventilation area and strengthening the protection against rainwater intrusion. It should be noted that the rain guide plate 12 and the rain shield plate 13 are set as two sets, which are respectively set at the air inlet and the air outlet.

[0040] Specifically, the inner wall of the frame 32 is bolted with an adsorption plate 14 for absorbing water vapor in the air.

[0041] The adsorption plate 14 can absorb water vapor in the air, thereby reducing the humidity inside the electricity meter body 1 and playing a moisture-proof role. The adsorption plate 14 is made of polyester fiber non-woven fabric. It should be noted that there are two sets of adsorption plates 14, and the other set is set as follows: Figure 3 As shown, one side of the rain guide plate 12 is installed on the air inlet side of the ventilation path, and a set is also provided at the outlet, so that the air is dehumidified before entering the electricity meter body 1 and then ventilated.

[0042] In use, the exhaust fan 33 is first turned on. External air enters the meter body 1 through the vertical groove at one end of the frame 32 and the adsorption plate 14. During this process, the air first flows through the adsorption plate 14 installed on the air inlet side. Its polyester fiber non-woven fabric structure adsorbs water vapor in the air, reducing humidity. Subsequently, the dry air is driven by the exhaust fan 33 and discharged from the meter body 1, carrying away heat and residual moisture through the vertical groove 31. At the same time, the rain guide plate 12 and the rain shield 13 prevent external rainwater from entering, avoiding the adsorption plate 14 from becoming damp and failing. Finally, the hot and humid air is discharged through multiple sets of vertical grooves 31 on one side of the meter body 1, forming a continuous moisture-proof circulation. The protective frame 4 is then installed. At time 1, the magnet 42 on the inner wall of the meter body 1 is brought close to the iron block 43 at the bottom of the meter body 1, and the connection is made by magnetic attraction. At the same time, the top of the protective frame 41 is inserted between the first vertical plate 6 and the second vertical plate 7, and the two sides are inserted between the first horizontal plate 8 and the second horizontal plate 9, so as to achieve multi-directional limiting, prevent the protective frame 41 from moving, firmly protect the bottom wiring interface of the meter body 1, and prevent illegal touch and wiring modification. If someone attempts to illegally disassemble the protective frame 41, the pressure of the pressure sensor body 5 will change after the protective frame 41 is disassembled. The pressure sensor body 5 will transmit the signal to the alarm light on one side of the meter body 1, triggering the alarm to alert the management personnel, so as to promptly detect and stop the theft of electricity.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
