Description

Mini dust catcher of column of filter inversion

Technical Field

The utility model relates to a dust catcher technical field specifically says a mini dust catcher of column of filter inversion.

Background

The mini dust collector is one kind of dust collector, and its main characteristic lies in that the volume is less, it is easy to take in, it is good to carry the performance, the mini dust collector includes the body, the body installs the electric motor, the wind wheel, the filter mainly in, after the electricity, the electric motor drives the wind wheel to rotate, the wind wheel rotates to produce the suction, the air sucks from one end, the other end discharges at a high speed, therefore the air of the dust collection part (formed by the suction nozzle and the dust storehouse) of the front end of the mini dust collector is sucked constantly, cause the inside of the mini dust collector to produce the instantaneous vacuum, and the external atmospheric pressure forms the negative pressure, in the process that the air is sucked constantly, debris such as the dust are detained in the dust storehouse, the air is discharged by the tail of the mini dust collector after the filter filters, the dust storehouse is the trade term, and does not mean that can only store the dust.

We exemplify several mini-cleaners that have been disclosed, illustrating the difficulties and deficiencies found by the applicant:

1. the patent document, entitled multipurpose mini vacuum cleaner under utility model No. CN 202341943U, describes that it includes a cylindrical housing 1, and the housing 1 is composed of two halves 2 which are split and folded together and a rear cover 3 which is installed behind the two halves 2. The front part of a shell 1 is provided with an air suction cover 4, an air blade cavity 5 is arranged in the air suction cover 4, filter screens 6 are arranged around the air blade cavity 5, an air blade 7 is arranged in the air blade cavity 5, an air suction opening 8 is arranged at the front end of the air suction cover 4, the air suction opening 8 is communicated with the air blade cavity 5, a motor 9 is arranged in the shell 1, a rotating shaft 10 of the motor 9 is connected with the air blade 7, a battery box 12 for installing a dry battery 11 is arranged in the shell l, a sliding plate switch assembly 13 for controlling the motor 9 to rotate is arranged on the shell 1, and brushes 14 are arranged around the air suction opening 8 on the front end surface. An air outlet 150 communicated with the fan blade cavity 5 is arranged on the shell 1 opposite to the fan blade cavity 5, and a protective cover 16 covering the air suction cover 4 can be arranged at the front end of the air suction cover 4 and covers when not used.

2. No. CN 208590990U, utility model name is a vehicle-mounted vacuum cleaner, this patent document describes, including casing 1, fan 2, filter 3, casing 1 is the cartridge type structure, casing 1 front end is provided with inhales grey mouth 4 and inside coaxial setting gradually to the back by preceding filter 3, fan 2, filter 3 will casing 1 is by the dust separation of front end opening entering and messenger fan 2 produced air current by filter 3 passes through, inhale grey mouth 4 is the cavity suction nozzle structure, inhale grey mouth 4 the cavity with form confined ash storehouse 5 between the filter 3, casing 1 rear end is provided with power module 7.

The shell l, the fan 2 and the filter 3 are arranged from front to back and form an internal cavity, and the suction nozzle 4 is of a streamline structure and is used for sucking ash. The filter blocks dust in the dust bin 5, and the structure is a base for mounting the power module 7 at the rear, and is different from a traditional common vehicle-mounted dust collector. The rear part of the general vehicle-mounted dust collector is not provided with the power supply module 7, so that the wind resistance is smaller, an air outlet is arranged, and the design of a simple shell is not needed.

3. The utility model is a mini-sized dust collector with the name of 92214546.6, which is described in the patent document, a cylindrical shell (1) is made of engineering plastics, and the interior of the shell is divided into two grids, wherein one grid is a battery box (2) which can be used for accommodating two batteries No. 1, and the structure of the shell is similar to that of a common flashlight; the other grid is a motor room (3), a motor (4) provided with fan blades and an arc streamline surface is pushed along a guide edge of the inner wall of the shell (a certain gap is reserved between the motor and the shell), and a screw pin (6) positioned on the shell is screwed in after the motor is in place, so that the motor is fixed on the shell. Uncovering the movable block (6) at the joint of the motor and the battery box, connecting the motor wire end into the three-position contact switch (7), and then installing the movable block (6). Four fixing holes (8) are drilled on the shell at the joint part of the fan case, and the fan case plays a role in ventilating and cooling the motor. This assembles the axial flow fan. Then the horn mouth of the horn-shaped connector (9) with the fabric filter screen (10) is connected with the shell mouth by a hook (11) and a button (12), and an elastic sealing ring (13) is padded at the interface. The small-diameter end of the connector is tapped with threads and is connected with an elbow suction brush (14) or a straight extension suction brush (15). The elbow suction brush has 150 degrees of curvature, and the brush head is triangular, so that dust on small areas and small corners can be adsorbed. The straight-extending suction brush (15) has a rod diameter reduced to an ellipse (the major diameter is 1.2cm, the minor diameter is O.8cm), the length is about 25cm, the brush head is also elliptical, five claw teeth (16) at the brush end are about lmm lower than the brush hair, and the brush can be used for scratching except absorbing dust in tiny spaces.

From the above, we can find that 1) the mini dust collector is small, but the related parts are more, so that the further improvement is difficult; 2) in the prior art of mini dust collectors, the research on the relation between the shell and other components is not enough, the main research content is still in the component part, and the shell mainly adapts to the design of the component part.
