Description

Technical Field

[0001] This application belongs to the field of antistatic structures for industrial vacuum cleaners, and specifically relates to an antistatic structure for a vacuum cleaner. Background Art

[0002] This technical solution is an optimized improvement based on the patent with the patent number 2023110095331 and the name: A self-cleaning system for a vacuum cleaner. When a pneumatic tool is working, such as a pneumatic grinder, it is necessary to suck away the dust generated during grinding in a timely manner to avoid serious environmental pollution of the working environment. However, the grinding time is intermittent. When not grinding, it is necessary to turn off the vacuum cleaner, and when grinding, it is necessary to turn on the vacuum cleaner separately, which increases the usage burden. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide an antistatic structure for a vacuum cleaner, which can solve the problem of the frequent manual startup steps of the vacuum cleaner.

[0004] The embodiments of this application provide an antistatic structure for a vacuum cleaner, including: a connecting clip, which is located at the air inlet of the vacuum cleaner; and the connecting clip is connected to the suction pipe at the air inlet of the vacuum cleaner;

[0005] The connecting clip is connected to the grounding structure through a wire. The connecting clip is provided with an end part, a first end rod, a groove part, a second end rod, a third end rod and a connecting base. The connection between the end part and the first end rod is a bent structure, and an obtuse angle is formed between the end part and the first end rod; the first end rod and the second end rod form the groove part; the second end rod is perpendicular to the third end rod, the connecting base is fixedly connected to the third end rod, and a through hole is provided on the connecting base; the connecting clip is integrally formed. The first end rod and the second end rod are parallel to each other or form a certain acute angle, which is convenient for clamping on the suction pipe at the air inlet of the vacuum cleaner, and the length of the first end rod is greater than that of the second end rod. A through hole with a width corresponding to the cross-section of the first end rod is provided on the suction pipe at the air inlet of the vacuum cleaner, which is convenient for the first end rod to pass through. The first end rod and the second end rod are clamped on the suction pipe, and the first end rod is located inside the suction pipe. Preferably, a number of bumps are provided on the first end rod to increase the surface area of the first end rod, which can better remove the charge carried by the dust in the suction pipe.

[0006] The connecting clip is located between a first fixing plate and a second fixing plate, and the first fixing plate and the second fixing plate are fixedly connected by screws. The first fixing plate is a symmetric structure, and the first fixing plate is fixedly connected to the ground wire through a fastener. The grounding structure is a flexible structure and has electrical conductivity. The grounding structure is an iron chain. There are at least two connecting clips. If the number of connecting clips is only one, the antistatic effect is not good. It is optimal that the connecting clips are evenly distributed circumferentially around the air inlet of the vacuum cleaner to balance the removal of charge.

[0007] This technical solution mainly achieves the purpose of removing static electricity by setting a static-conducting connecting card at the air inlet of the vacuum cleaner, and then transporting the charge on the connecting card to the ground through a wire and a grounding structure. It conducts static electricity at the air inlet to prevent charged dust from adhering to the inner cavity of the vacuum cleaner, thereby protecting the safety of the inside of the vacuum cleaner.

DETAILED DESCRIPTION

[0014] Example

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0016] In the following, in combination with the accompanying drawings, a vacuum cleaner static electricity removal structure provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0017] refer to Figures 1-4 , a vacuum cleaner static removal structure provided in an embodiment of the present application may include:

[0018] The connecting clip 250 is located at the air inlet 110 of the vacuum cleaner; and the connecting clip 250 is connected to the suction pipe 300 at the air inlet 110 of the vacuum cleaner; the connecting clip 250 is connected to the grounding structure 220 through a wire 240, and the charge collected by the connecting clip 250 is led to the ground through the grounding structure 220, thereby realizing the transfer of charge.

[0019] The connecting clip 250 is provided with an end portion 251, a first end rod 252, a groove portion 253, a second end rod 254, a third end rod 255 and a connecting base 256. The connection between the end portion 251 and the first end rod 252 is a bent structure. As Figure 4 shown, the bent structure at the connection between the end portion 251 and the first end rod 252 can enhance the stability of the end portion 251. The bent structure can provide a certain elastic force to buffer a part of the vibration force of the wind speed between the end portion 251 and the first end rod 252 on the end portion 251.

[0020] Preferably, an obtuse angle is formed between the end portion 251 and the first end rod 252; the closer the end portion 251 and the first end rod 252 are to being parallel, and the closer the angle between the two is to a flat angle, the less the end portion 251 blocks the dusty wind in the pipeline. The first end rod 252 and the second end rod 254 form a groove portion 253; the groove portion 253 is mainly for clamping on the suction pipe. The second end rod 254 is perpendicular to the third end rod 255, which is convenient for installation. The connecting base 256 is fixedly connected to the third end rod 255, and the connecting base 256 is provided with a through hole to facilitate the passing of screws for fixing; preferably, the connecting clip 250 is an integral sheet metal part and is integrally formed.

[0021] As Figure 4 shown, the first end rod 252 and the second end rod 254 are parallel to each other, and the length of the first end rod 252 is greater than the length of the second end rod 254. The longer length of the first end rod 252 can increase the length of the first end rod 252 in the pipeline, and then increase the contact area between the first end rod 252 and the dust in the pipeline, and can effectively absorb the charge in the pipeline of the suction pipe 300 and transfer the charge to the ground.

[0022] As Figure 3 shown, the connecting clip 250 is located between the first fixing plate 230 and the second fixing plate 260. Preferably, there are at least two connecting clips 250, and they are evenly distributed circumferentially around the air inlet 110 of the vacuum cleaner.

[0023] The distance between the first fixing plate 230 and the second fixing plate 260 is close, so that the connecting clip 250 fits tightly against the first fixing plate 230, ensuring good electrical conductivity. The first fixing plate 230 and the second fixing plate 260 are fixedly connected by screws.

[0024] The first fixing plate 230 is of a symmetric structure, which can more conveniently facilitate the installation and connection of the clamping member 250, enabling uniform force on both sides of the suction pipe 300. The first fixing plate 230 is fixedly connected to the ground wire 270 through the fastener 280. The tip of the fastener 280 abuts against the first fixing plate 230. There is also a ground wire 270 inside the vacuum cleaner. If there is a ground wire on the socket, the charge on the clamping member 250 can also be conducted out through the ground wire 270. If there is no ground wire on the socket, the ground wire 270 can conduct the possible leakage current inside the vacuum cleaner through the first fixing plate 230, the wire 240 and the grounding structure 220, protecting the electrical safety of the vacuum cleaner.

[0025] The grounding structure 220 is a flexible structure and has good electrical conductivity. Generally, it is an iron chain. However, there is a relatively large friction noise between the iron chain and the ground. Preferably, the grounding structure 220 is a hose or a rubber part with good electrical conductivity to reduce the noise.

[0026] Through the above technical solution, it is possible to avoid the accumulation of charged dust inside the vacuum cleaner, thereby preventing the breakdown of internal electronic components of the vacuum cleaner and avoiding danger.

[0027] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
