Description

1. TECHNICAL FIELD

The invention belongs to the technical field of deicing tools, and particularly relates to an electric defroster.

2. BACKGROUND ART

When the temperature is lower in winter, the automobile glass, the sentry glass observation window and the like are prone to freeze or form frost, influencing normal use of automobiles. In order to remove the ice, silicone scraper or hard utensil is usually adopted for manual scraping, the efficiency of which is low and unable to completely scraping the ice; besides, it is difficult to control the scraping strength as too light strength is difficult to scrap the ice and too strong force tends to scratch the glass, wasting time and labor.

3. SUMMARY OF THE INVENTION

In order to overcome shortcomings in prior art, the invention provides an electric defroster with convenience, high efficiency, and wide applicability.

The technical scheme adopted by the invention is an electric defroster, comprising

• • a housing with a handle;
  • a working wheel rotatably connected with the housing and at least partially protrudes out of the surface of the housing, scraping pieces extending along the axial direction is arranged on the surface of the working wheel;
  • a power mechanism is used for driving the working wheel to rotate relative to the housing;
  • the power mechanism drives the working wheel to rotate relative to the housing; the scraping pieces rotate in the circumferential direction to scrape ice.

The invention utilizes the working wheel to roll and deice the glass surface; compared with scraping ice with whole bottom surface stick to the glass surface, the flexibility of the position for scraping ice of the invention is higher and the ice at the corner can be effectively scraped; the scraped ice is discharged outward rather than in all directions and does not adversely affect continuous scraping; in addition, the working wheel can contact with the glass surface line to scrape ice with smaller contact area, or there are more contact surface can be selected, which makes ice scraping more flexible.

Furthermore, the working wheel is cylindrical, and the scraping pieces protrude outwards from the surface of the working wheel. The working wheel is cylindrical, and the ice can be uniformly scraped at the periphery after rolling; the scraping pieces protrude from the surface of the working wheel, so that the scraping efficiency for freezing is higher.

Furthermore, there are a plurality of scraping pieces extend spirally, and are distributed at intervals along the circumferential direction of the working wheel. The spiral design ensures that the working wheel can realize ice scraping not necessarily being contacted with the surface of the glass in the whole axial direction, and only the working wheel partially contacted with the glass can realize ice scraping, so it is more flexible in use; the scraped ice is quickly discharged from the space between the adjacent scraping pieces, ensuring the ice scraping efficiency.

Furthermore, the height of the scraping pieces protruding from the surface of the working wheel is gradually increased along the direction in which the wheel is rotated, avoiding the ice being accumulated between the adjacent scraping pieces, meanwhile, the protruding height of the contact point between the scraping piece and the glass surface can be increased, thus having better ice scraping effect is and the ice scraping operation is more labor-saving.

Furthermore, the power mechanism comprises a power source, a speed reduction unit connected with the output shaft of the power source, and a conveyor belt connected with the speed reduction unit and the working wheel. The load for the conveyor belt is great, even slipping happens in the course of the work, which can not lead to the damage of power source, and further extend power mechanism's using life.

Furthermore, the speed reduction unit comprises the first speed reduction gear and the second speed reduction gear which are in meshing transmission; the power source is a motor which is arranged in parallel with the working wheel. The layout is reasonable, and the output efficiency of the power source is more matched with the rotating speed of the working wheel.

Furthermore, tooth is provided on the rotation shaft of working wheel, said first speed reduction gear is coaxially provided with a first auxiliary gear, said second speed reduction gear is coaxially provided with a second auxiliary gear, wherein said first auxiliary gear is in mesh transmission with the second speed reduction gear, and said second auxiliary gear and the tooth are connected by conveyor belt.

Furthermore, on said housing is provided with a protective cover at the position corresponding to the working wheel; on said housing is provided with an auxiliary illuminating lamp. The protective cover guides the scraped object in the target direction and avoids injury to the user due to splashing of the ice removed by rolling of the scraping piece; the auxiliary illuminating lamp is convenient for use at night.

Furthermore, said housing is connected to an extension bar, said handle is connected to the end of the extension bar, which is convenient for deicing at high or distant place and more flexible in use.

Furthermore, said working wheel is covered with a working layer on the outside. The working layer can be used for sticking hair, or for cleaning, or for removing rust, or for polishing.

The advantageous effects obtained by the invention is as follow: the invention utilizes the working wheel to roll and deice the glass surface, the flexibility of the position for scraping ice is higher and the ice at the corner can be effectively scraped; there are more contact surface can be selected, which makes ice scraping more flexible; the scraped ice is quickly discharged from the space between the adjacent scraping pieces, ensuring the ice scraping efficiency; the invention can not only be used for scraping ice, but also can be used for cleaning and removing rust.
