Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a dry and wet dual-purpose vacuum cleaner box structure. Background Art
[0002] As people's environmental awareness increases, the requirements for vacuum trucks are getting higher and higher. Customers not only require vacuum trucks to have a higher primary suction rate, higher working speed, lower noise, lower fuel consumption, and absolutely no secondary dust pollution, but also require them to be able to work all-weather in spring, summer, autumn, winter, rainy and sunny days.
[0003] The existing wet and dry vacuum cleaner trucks are only equipped with one switching door in the compartment. The switching door is controlled to be opened or closed as needed during dry suction or wet suction. Switching between the two vacuuming modes by only one switching door may easily cause dust during wet suction to enter the filter device. During wet suction, due to the high moisture content, the filter device may be easily damaged, which is not conducive to extending its service life. Summary of the invention
[0004] In order to overcome the deficiencies in the prior art, the utility model provides a dry and wet dual-purpose vacuum cleaner box structure, which comprises a box body, wherein the space inside the box body is divided into a primary filtration area and a fine filtration area by a partition, a dust suction pipe is arranged in the primary filtration area, a dry suction door and a wet suction door with the same structure are respectively arranged on the partition, the wet suction door is connected to the air suction port of the fan through an air duct, a filtering device is arranged in the fine filtration area, an air outlet connected to the air duct is arranged on the top of the filtering device, a dry suction air outlet door is installed at the air outlet, a filter screen is fixedly installed on the partition, and the filter screen encloses the dry suction door and the wet suction door therein.
[0005] In order to facilitate the opening and closing of the dry suction door and the wet suction door, the dry suction door includes a mounting plate 1, and a connecting seat 1 and a connecting seat 2 are respectively provided at both ends of the mounting plate 1. An oil cylinder 1 is movably mounted on the connecting seat 1, and the connecting seat 2 is movably connected to a fixed seat 1, and the fixed seat 1 is fixedly connected to a door panel 1, and the other end of the oil cylinder 1 is movably connected to the fixed seat.
[0006] In order to operate the opening and closing of the dry suction air outlet door, the dry suction air outlet door includes a mounting plate 2, and the two ends of the mounting plate 2 are respectively movably connected to an oil cylinder 2 and a fixing seat 2, the fixing seat 2 is fixedly connected to the door panel 2, and the other end of the oil cylinder 2 is movably connected to the fixing seat 2.
[0007] The beneficial effect of the utility model is that the utility model corresponds to two different dust suction states and sets different dust suction doors. By opening or closing the dry suction door and the wet suction door, different dust suction purposes are achieved. Especially during wet suction, it directly enters the fan suction port from the air duct, and will no longer cause damage to the filter device, which is beneficial to extending the service life of the filter device.
