[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] Example

[0020] Please refer to the accompanying drawings in the specification. In this embodiment of the present invention, a static electricity removal device for a vacuum cleaner includes:

[0021] Electrostatic discharge assembly: The electrostatic discharge assembly includes an electrostatic discharge circuit and a conductive metal. The electrostatic discharge circuit is located on a circuit board, which is located inside the electrical box 2. The conductive metal is located on the same surface as the vacuum cleaner 1. The conductive metal is connected to the electrostatic discharge circuit via a wire.

[0022] Grounding device: includes electrostatic chain 3 and connector 4, the connector 4 is a metal connector, the connector 4 is mounted on the metal frame of the vacuum cleaner 1, and the electrostatic chain 3 is mounted on the connector 4;

[0023] Electric field detection sensor: The electric field detection sensor is installed inside the vacuum cleaner and in the pipes inside the vacuum cleaner;

[0024] Conductive material covering layer: The conductive material covering layer is disposed on the inner wall of the pipe and the surface of the filter element of the vacuum cleaner 1.

[0025] Furthermore, the housing of the vacuum cleaner 1 is made of metal.

[0026] Furthermore, the bottom end of the electrostatic chain 3 is in contact with the ground.

[0027] Furthermore, the conductive material covering layer uses conductive rubber or metal foil, which are common materials that are easy to process and install. It can meet the requirements for conductivity and static electricity removal, and can also adapt to the complex shape and structure of the vacuum cleaner, ensuring a good covering effect.

[0028] Furthermore, the electric field detection sensor has a monitoring accuracy of ±50V / m and a detection range of 100-500V / m. It can accurately capture the static electricity status at each stage of equipment operation, allowing users to understand the static electricity level in a timely manner and take corresponding measures in case of abnormalities, ensuring stable equipment operation and improving safety.

[0029] Furthermore, the conductor is a multi-strand copper core conductor with a cross-sectional area of ​​0.5 square millimeters, and both ends of the conductor are equipped with waterproof and oxidation-resistant metal connectors.

[0030] Furthermore, the circuit board is equipped with overload protection and leakage protection modules, which can prevent abnormal current during the electrostatic discharge process from causing equipment failure or even safety accidents, and extend the service life of the equipment. The conductors are multi-strand copper core conductors with a cross-sectional area of ​​0.5 square millimeters, and both ends are equipped with waterproof and anti-oxidation metal connectors, which ensures the stability and durability of the electrostatic conduction circuit and reduces the risk of circuit aging and damage.

[0031] Working Principle: After the vacuum cleaner generates static electricity during operation, it is distributed throughout the vacuum cleaner surface, the inner wall of the pipes, and the filter. Conductive metal surfaces on the same surfaces collect this static electricity, which then travels along wires into the electrostatic discharge circuit. Simultaneously, the conductive material covering the inner wall of the pipes and the surface of the filter also guides the static electricity to the electrostatic discharge assembly for centralized collection. The static electricity collected by the electrostatic discharge assembly is then conducted to the grounding device via wires. The electrostatic chain, a key component of the grounding device, is mounted on the vacuum cleaner's metal frame using connectors. Because the bottom end of the electrostatic chain is in contact with the ground, the static electricity is continuously released into the earth along this path, achieving the purpose of eliminating static electricity. Throughout the process, an electric field detection sensor monitors the electric field strength inside the vacuum cleaner and in the pipes in real time. If the detected static electricity level exceeds the normal range (100-500V / m), the user can troubleshoot the anomaly based on the monitoring data and, in conjunction with overload protection and leakage protection modules, maintain the stability of the electrostatic discharge system, ensuring the safe and efficient operation of the vacuum cleaner.

[0032] In the above process, the electrostatic discharge component of this utility model, combined with a grounding device, forms a complete electrostatic discharge path. The electrostatic discharge circuit is connected to the conductive metal on the surface of the vacuum cleaner, which can quickly collect the static electricity generated during the operation of the vacuum cleaner, and then conduct the static electricity to the ground through the electrostatic chain, completely eliminating the potential risks caused by static electricity accumulation and avoiding dust adsorption due to static electricity during vacuuming, which would affect the cleaning effect. The conductive material covering layer covers the inner wall of the vacuum cleaner pipe and the surface of the filter element, further expanding the range of static electricity discharge, reducing dust adhesion to these key parts due to static electricity, and maintaining the stable and efficient vacuuming ability of the equipment.
