Technical field

The utility model relates to cleaner technology field more particularly to a kind of dust catchers that can cut silk thread.

Background technique

Dust catcher is common cleaning equipment now.Dust catcher drives dust suction blade high-speed rotation by motor, thus Air negative pressure is generated in the shell of sealing, absorbs extraneous dust clast, Small-sized suction cleaner is due to taking conveniently, the scope of application Extensively, it is more and more used in today's society.

Authorization Notice No. is CN 205458418U in Chinese patent literature, and authorized announcement date is on August 18th, 2016 open Entitled " a kind of portable whirlwind dust exhaust apparatus " utility model patent, this application discloses a kind of portable whirlwind dust suctions to fill It sets, including main machine body, dust suction floor mop, main machine body is equipped with handle, dirt cup, fuselage blast pipe, induced-draught electric motor, and dust suction floor mop includes Floor mop matrix, insertion pipe, insertion pipe lower end are connected to air duct in floor mop, and insertion pipe upper end is clamped and is connected to fuselage blast pipe, Filtering net cylinder is equipped in dirt cup, dirt cup is equipped with tangent air inlet, upper end exhaust outlet, and filtering net cylinder is equipped with multiple filter hole, Tangent air inlet is connected to fuselage blast pipe, and upper end exhaust outlet is connected to the air intake of induced-draught electric motor, the outlet air end of induced-draught electric motor It is connected to the outer exhaust outlet being located in main machine body.Disadvantage is that: dust catcher is easy when absorbing the silk thread or the scraps of paper of agglomerate Block the air duct inside dust catcher, although the suction of dust catcher can by the silk thread of agglomerate and scraps of paper inspiration to dust catcher, But when blocking air flue inside dust catcher due to silk thread and the scraps of paper, can in dust catcher motor and air flue cause stress, influence The service life of dust catcher reduces the stability of dust catcher dust suction.

Therefore design a kind of dust catcher that can cut agglomerate silk thread and the scraps of paper just it is necessary to.

Utility model content

The silk thread or the scraps of paper that the utility model will overcome dust catcher in the prior art that cannot be cut into inside dust catcher, Lead to the susceptible to plugging deficiency in air duct inside dust catcher, provides a kind of dust catcher that can cut silk thread, dust suction can be cut into Silk thread and the scraps of paper inside device improve the stability of dust catcher dust suction air pressure.

To achieve the goals above, the utility model adopts the following technical solution.

A kind of dust catcher that can cut silk thread, including main machine body, floor mop and dirt cup, dirt cup are located at the lower end of main machine body, dirt Blast pipe is equipped between cup and floor mop, the upper end of dirt cup is equipped with induced-draught electric motor, filtering screen is equipped between induced-draught electric motor and dirt cup, The downside of floor mop is equipped with the suction inlet that be connected to blast pipe, is equipped with cutting blade in suction inlet, the both ends of cutting blade equipped with The connector of floor mop connection, floor mop are equipped with the interface of cooperation connector, connector and interface gaps cooperation, and connector, which is externally provided with, can experience pressure The sealing shroud of power deformation.

By the way that the cutting blade of suction inlet, the sealing shroud material softer using quality, due in dust catcher is arranged in By external pressure creeping deformation can be occurred for outer draught head, caused the change in location of cutting blade, be drawn onto dust catcher big When rubbish, there is instantaneous variation in the pressure in air duct inside dust catcher, causes sealing shroud to deform, causes the vibration of cutting blade, energy Enough significantly improve the cutting effect of cutting blade, guarantee the reliability of cutting blade cutting, when dust catcher dust suction can for into The bulk rubbish, paper scrap, silk thread etc. for entering dust catcher carry out cutting the airflow channel prevented from blocking in dust catcher, reduce in dust catcher The pressure that induced-draught electric motor and other parts are subject to when portion channel is plugged enhances the service life of dust catcher；Prevent dust catcher Air flue is plugged, the stability of stream pressure when improving dust catcher dust suction.

Preferably, cutting blade is strip, the both ends of cutting blade are fixed on the opposite two sidewalls of floor mop.Cutting Blade is across the cutting efficiency in floor mop, improving cutting blade.

Preferably, the radial section of cutting blade is shuttle shape broad in the middle pointed at both ends, the connector on cutting blade is Prismatic.The connector of prismatic facilitates the blade of cutting blade to position, and enables the blade face suction inlet of cutting blade, improves cutting The cutting power of blade；The twice cutting edge of cutting blade is sharp, ensure that the cutting sharpness of cutting blade, intermediate sizes It is larger, the intensity of cutting blade can be enhanced, improve the service life and non-deformability of cutting blade；The radial direction of cutting blade Section is shuttle shape, can reduce the air drag that cutting blade is subject to, and while guaranteeing that dust catcher dust suction effect is stablized, is improved Cutting efficiency.

Preferably, sealing shroud includes sealing ring and diaphragm seal, seal ring set is located at connector side, and diaphragm seal can cover in On the outside of interface.Sealing shroud completes the sealing of connector and interface, prevents the junction gas leakage of connector and interface, prevents connector and connects The dust removal ability of dust catcher is influenced at mouthful there are gap.

Preferably, sealing shroud is made of silica gel material.The quality of silica gel is more soft, can be used as connector and interface The buffering of connection reduces the rigid impact of connector and interface；The quality of silica gel is more soft, in dust catcher work, dust catcher Internal pressure is lower, and extraneous air pressure can pull sealing shroud to the inside of dust catcher, so as to enhance connector and The sealing performance of interface.

Preferably, the axis of induced-draught electric motor is parallel with the axis of dirt cup or is overlapped, the axis of filtering screen and air draught electricity Axis where machine forms angle.The axis of induced-draught electric motor and the axis of dirt cup it is parallel or be overlapped, improve the aeolian currents of dust catcher To enhancing the suction of dust catcher；The axis of filtering screen and the axis where induced-draught electric motor form angle, increase on filtering screen Filtering surface area, improve dirt cup in poly- dirt effect.

The utility model has the beneficial effect that the silk thread and the scraps of paper that can be cut into inside dust catcher, improves dust suction The stability of device dust suction；And the axis of dirt cup is parallel or coincidence, the wind-force for improving dust catcher flow to, enhancing for the axis of induced-draught electric motor The suction of dust catcher；There are angles for filtering screen and induced-draught electric motor axis, increase the area of filtering surface on filtering screen, improve dirt Poly- dirt effect in cup.
