Description

A kind of domestic suction cleaner

Technical field

The utility model relates to a kind of domestic suction cleaner, particularly relates to a kind of vacuum cleaner that can conveniently remove machine inner product dirt.

Background technology

Along with the raising of people's living standard, the continuous improvement of living conditions, people more and more pay attention to the cleaning of living environment, and domestic suction cleaner is now a large amount of enters family.

Existing domestic suction cleaner usually with the storage dirt bag that is provided with in the machine, uses as the rubbish filtering device, and therefore, storage dirt bag just plays air filtration and collects the dual-use function of rubbish.

The material of storage dirt bag generally all adopts cotton-spinning fiber to make, and therefore, use repeatedly after storage dirt bag can clean, but the laying dust cleaning work is simultaneously also unhygienic than trouble; The storage dirt bag that adopts the paper fiber to make is also arranged, and it can only disposablely use, and is simple to the cleaning work of machine.Disposable storage dirt bag made of paper has consumed a large amount of wood fibres, and also with unfavorable, user's cleaning cost is also high simultaneously to the forest tree resource protection.

In addition, existing dust catcher when a spot of laying dust is adsorbed in the storage dirt bag, will store up the fiber hair hole plug on the dirt bag easily after use, filter effect is obviously descended.Therefore, people wish to have a kind of efficiency of dust collection height, and the cleaning work of soaking is simple, and the domestic vacuum cleaners that cleaning cost is cheap occur.

Summary of the invention

The purpose of this utility model provides a kind of air filtration performance of having improved, and improves efficiency of dust collection, and can conveniently remove the domestic suction cleaner of machine inner product dirt.

The technical solution of the utility model is: a kind of domestic suction cleaner, comprise the casing housing, the dust absorption passage and the dust absorption fan that constitute by inlet scoop, air outlet, flexible pipe socket, induced duct, airflow duct, also include the disposal box of forming by casing and case lid, casing is provided with airflow duct, and duct entry docks with induced duct on being installed in the casing housing.In the disposal box casing, be provided with anti-misuse device,, be provided with anti-misuse inserted sheet in the corresponding position of case lid.In the disposal box casing, also be provided with the dust filter, this device is propped up by guard, filter core, guard and is configured to, in the guard support, be provided with ventilating duct, ventilating duct one end docks with filter core, the other end docks with motor room's air inlet, filter core is placed in the guard, and together is integrated with the installation of guard support.The guard surface is provided with reticular fibre and closes helical form keel skeleton.Cartridge surface is for filtering extra large handkerchief, folding shape hollow structure.

Guard surface in the dust filter of vacuum cleaner of the present utility model is provided with reticular fibre and helical form keel skeleton, and dust-absorbing airflow is flowed along the keel skeleton, forms spiral air flow, and the rubbish that quality is big carries out centrifugation; And cartridge surface folds the shape hollow structure for filtering extra large handkerchief, and air-flow is carried out secondary filter, has improved the air filtration performance.And the dust filter has adopted separable structural design scheme, and guard, filter core, guard support can take out in disposal box easily, are convenient to cleaning.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described further.

As shown in the figure, a kind of domestic suction cleaner, comprise the casing housing, dust absorption passage and dust absorption fan (3) by inlet scoop (1), air outlet (2), flexible pipe socket (6), induced duct (7), airflow duct (8) formation, also include the disposal box of forming by casing (4) and case lid (5), casing (4) is provided with airflow duct (8), and duct entry docks with induced duct (7) on being installed in the casing housing.Be provided with anti-misuse device (14) in disposal box casing (4), the corresponding position in case lid (5) is provided with anti-misuse inserted sheet (15).In disposal box casing (4), also be provided with dust filter (9), this device is made of guard (10), filter core (11), guard support (12), in guard support (12), be provided with ventilating duct (13), ventilating duct (13) one ends dock with filter core (11), the other end docks with motor room's air inlet, filter core (11) is placed in the guard (10), and together is integrated with guard support (12) installation.
