Problems solved by technology

For this problem, the solution is also different. The blower and suction fan disclosed in the Chinese patent CN103382708 discloses a solution that introduces static electricity into the cloth bag and then releases static electricity when the cloth bag touches the ground. And release static electricity, but not completely, there are hidden dangers, because cloth bags are generally not used as grounding objects
In addition, the cloth bag cannot be in contact with the ground in actual use, otherwise it will cause inconvenient use and friction damage to the cloth bag. If the operator is taller, the dust bag will be far away from the ground, and the static electricity will not be released. The risk of static electricity still exists

Embodiment 1

[0020] Example 1, such as Figure 1 to Figure 4 As shown, an electrostatic discharge structure of a blower fan includes a casing 1 provided with an air outlet 12 and a dust bag 7 connected to the air outlet 12. The casing 1 is provided with a main handle 11, and the dust bag 7 is A ground wire 6 is provided, and the casing 1 and the dust bag 7 are electrically connected through a conductive device. The casing 1 is laid with a conductive wire 15 for guiding the static electricity on the casing 1. The conductive wire 15 and the grounding wire 6 are connected to the conductive device. Discharged into the earth, the harm of static electricity to machines and operators is completely solved.

[0021] Further, the ground end of the ground wire 6 is provided with a metal ground component 9 . The purpose of installing the metal grounding part 9 is to increase the weight of the grounding wire 6 to prevent the grounding wire 6 from being blown up, and at the same time increase the cont...

Embodiment 2

[0027] Example 2, such as Figure 1 to Figure 4 As shown, on the basis of Embodiment 1, the grounding wire 6 is fixed on the dust bag 7. Specifically, a strip-shaped hidden belt 71 can be sewn on the dust bag 7, and the grounding wire 6 is removed from the hidden belt 71. Passing through, not only hides the grounding wire 6, but also avoids the potential safety hazard caused by the exposure of the wire. The ground end passes through the drag strip 8, so that the ground wire 6 is hidden as a whole.

[0028] Specifically, the length of the towing belt 8 beyond the dust bag 7 is greater than 40 millimeters, a part of the grounding wire 6 is hidden in the hidden belt 71, and the remaining part is hidden in the towing belt 8, so that the fixed frame 4, the metal conductive rod 5, the dust bag 7, The grounding wire 6, the drag strip 8 and the metal grounding part 9 are combined into an integral part, which can be disassembled from the casing, which is convenient for the operator to...

Abstract

The invention discloses an electrostatic discharge structure of a blow and suction ventilator. The electrostatic discharge structure comprises a case, a dust collection device and a conducting device, wherein an air outlet is formed in the case; the dust collection device is connected with the air outlet; the conducting device is arranged on the case; the electrostatic discharge structure is also provided with a ground lead which is electrically connected with the conducting device; and a ground terminal of the ground lead is in direct contact with the ground. According to the electrostatic discharge structure, the ground terminal of the ground lead is in direct contact with the ground, so that static electricity is directly discharged into the earth; the harm of the static electricity to a machine and an operator is thoroughly eliminated; and meanwhile, the problem that a dust collection bag must be in contact and rubbed with the ground in use is solved.

Description

technical field [0001] The invention relates to garden machinery, in particular to a blower and suction fan. Background technique [0002] Static electricity generated by friction is an objective natural phenomenon. At present, when gasoline and DC blowers in the domestic and foreign markets are sucking dry leaves and fine dust, relatively strong static electricity will be generated on the surface of the shell under the high-speed rotation of the fan blades. Because the casing of the blower is non-metallic and not grounded, the static electricity generated cannot be effectively released, and it usually accumulates on the metal parts and the outer surface. When the static electricity accumulates to a certain extent, it will damage the internal electronic components of the machine and cause electric shock Operator's risk. For this problem, the solution is also different. The blower and suction fan disclosed in the Chinese patent CN103382708 discloses a solution that introduce...
