Description

Pumping equipment

The present invention relates to a kind of pumping equipment.

Known pumping equipment, as vacuum cleaner, comprise the motor that has fan, fan produces swabbing action and is assemblied in the downstream that a mixture with air and chip aspirates into the collecting chamber in it, and is positioned at the filter that collecting chamber is used to purify the air that is aspirated.

Thereby the air that fan aspirated surrounds motor in the downstream of filter and cools off it, turns back in the environment afterwards.Provide a device that is used as the carrier pipe of air and crumb mixture in the collecting chamber, this carrier pipe has one day end and to the outside to put in opposed end in the collecting chamber.

Collecting chamber has an opening that it is connected with the outer shell base of filter, successively, the outer shell base of this filter also has an opening that it is connected with the assembling stand of motor, and is last, the assembling stand of motor have an opening towards outside so that make the air that purifies from box shape body, draw.

First shortcoming of known this pumping equipment is the operating period pump unit, and promptly motor and fan have produced significant noise.

Another shortcoming is that the cooling effect of motor is unsatisfactory, because air effect can be overheated at the too short motor that consequently causes when service time is long relatively of the time interval of motor outer surface.Purpose of the present invention will be improved prior art exactly.

An object of the present invention is to make pumping equipment to reduce operation noise significantly.

This aspirator comprises motor 106, and the motor effect makes in first chamber device, the 3 inner vacuum that produce and aspirates the air that is full of dust, and wherein air is being drawn dust.

Be provided with labyrinth sealing (labyrinth) device 7 between the aspirator 6 and second outlet 5, it is used to reduce described aspirator 6, the i.e. operation noise of motor 106.

According to the preferred embodiment of pumping equipment 1, housing 2 comprises housing lower half 102 and upper half-shell 202, and upper half-shell 202 is by using jockey and housing lower half 102 crossovers.

First chamber device 3 and first inlet 4 in housing lower half 102 and second outlet 5 in upper half-shell 202.

At length, first chamber device 3 comprises first collecting chamber 8, and the dust of suction leaves in this first collecting chamber; The bracing or strutting arrangement 9 of motor 106, it is placed in the lane device 10 of first collecting chamber 8 and air, and air is drawn into second outlet 5 by bracing or strutting arrangement 9 from first collecting chamber 8.

The latter comprises container body 11, and container body 11 comprises shaping veil 12, and this veil is closed housing lower half 102 at the top and extended in first collecting chamber 8.

There are a series of openings 13 in the lower area of container body 11, and these openings are included in the lane device 10 of suction air.

Labyrinth sealing device 7 comprises other chamber device, be to disclose more specifically below, this chamber device be placed on first collecting chamber 8 and second the outlet 5 between and this device is connected with the latter and they between have connection opening, formed the labyrinth sealing in so a kind of mode, by the sealing of this labyrinth can make the air of suction after cooling motor 106, force by.

Other chamber device comprises second Room 14, and it is in bracing or strutting arrangement 9, more properly around the motor in container body 11 106; The 3rd Room 15, it is positioned at above second Room 14 in upper half-shell 202; Fourth ventricle 16, it is in upper half-shell 202, on the 3rd Room 15; And the 5th Room 17, it is in upper half-shell 202 and surround fourth ventricle 16.

Second Room 14 has almost surrounded whole motor 106 and comprised that first inlet, 18, the first inlets 18 of suction air communicate with first collecting chamber 8 on the latter's bottom and by opening 13; And first outlet, 19, the first outlets 19 communicate with the 3rd Room 15 in the top of second Room 14.

The 3rd Room 15 has second inlet of suction air in the bottom, this second inlet perpendicular positioning is so that corresponding with first outlet 19; The 3rd Room 15 also has the 3rd outlet 20, the three outlets 20 and places the latter's top and communicate with fourth ventricle 16.

Fourth ventricle 16 has the 3rd inlet of suction air, and the 3rd inlet perpendicular location is so that corresponding with the 3rd outlet 20; Fourth ventricle 16 also is equipped with the 4th outlet 21, the four outlets 21 around annular wall (perimeter walls) 116, and annular wall 116 is determined it and with communicating with the 5th Room 17 that its is provided with.

The latter has the 4th inlet of suction air; the 4th inlet is corresponding with the 4th outlet 21; and the 5th outlet 22, the five outlets 22 put in the 6th other Room 23, and the 6th Room 23 is equipped with and is used to be communicated with the 6th outside opening 24 and protected by grid 25.

Contain second filter 28 in the inside of the 6th Room 23, this second filter 28 has micropipe, if require, also can be activated carbon structure.

Fourth ventricle 16 made be suitable as housing seat shape, to hold first filter 26, in a preferred embodiment, first filter 26 comprises with the self-contained porous body 27 of sponge kind material.

The operation of pumping equipment is as follows: the air and the dust of suction enter in first collecting chamber 8 by first inlet 4 by motor 106 actions, and first inlet 4 can be equipped with the crooked pipe that extends.

The suction action of motor 106 causes the formation of circular flow in first collecting chamber 8, this circular flow surrounded container body 11 and it rises to second Room 14 by opening in before, be released in first collecting chamber 8 by gravity and centrifugal force dust that will collect, that remarkable weight is arranged.
