Description

Hand filter

Technical field

The utility model relates to a kind of filter, particularly relates to a kind of hand filter.

Background technology

General hand filter, such as the disclosed a kind of portable type water treatment facilities of TWM442873 Patent Case, comprise the second filter that first filter with a water inlet, inflator, one have a delivery port, one and be arranged at the first non-return valve between this first filter and this inflator, second non-return valve that is arranged between this inflator and this second filter, and a pressure accumulation cylinder that is arranged between this second non-return valve and this second filter.

When on when drawing this inflator, can produce negative pressure is pulled a fluid and flows into this inflator after entering this first filter by this water inlet, when pressing down this inflator, thereby the fluid that is positioned at this inflator can be stopped by this first non-return valve and enter this second filter by this second non-return valve and flows out in this delivery port.

Although seeing through this inflator of operation, above-mentioned composition carries out piston movement to filter, but this inflator is drawing water at every turn and is sending that to have the regular hour between water poor, in order to keep sending differential water pressures and to alleviate the operation power, must add to arrange this pressure accumulation cylinder, the complicated integral structure degree is high and bulky.

The specific embodiment

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

Consult Fig. 1, Fig. 2 and Fig. 3, the preferred embodiment of the hand filter of the utility model is applicable to filter a fluid, and comprises a housing unit 1, a filter core 2 and a pump unit 3.

This housing unit 1 comprises a lid 11 and a housing 12.

This lid 11 has a room 111, and is communicated with respectively a pod apertures 112 and a first flow 113 of this room 111.This housing 12 has the filter chamber 121 and second runner 122 that are communicated with this pod apertures 112.

This filter core 2 is arranged at this filter chamber 121 and intercepts this filter chamber 121 and this second runner 122, and in the present embodiment, this filter core 2 comprises one near the coarse filtration section 21 of this lid 11, and one in contrast to this coarse filtration section 21 and be close to the fine filtering section 22 of this second runner 122.

This pump unit 3 comprises that one is the separation group 32 that eccentric setting is embedded in this rotating shaft 31 in this room 111 and the rotating shaft 31 that can rotate around self axis, energy along radially sliding of this rotating shaft 31 and fits in these lid 11 inner peripheral surfaces with respect to this lid 11, and one is fixedly arranged on this rotating shaft 31 and exposes to this housing unit 1 and can drive the rocking handle 33 that this rotating shaft 31 is rotated.

This rotating shaft 31 has an axle body 311, and a slideway 312 that radially runs through this axle body 311.

This separation group 32 has two and is slidedly arranged on respectively the shim 321 of this slideway 312, a limit shaft 322 that is arranged in described shim 321 and is extended through this slideway 312, reaching one is sheathed on this limit shaft 322 and provides elastic force that described shim 321 is abutted against in the elastic component 323 of this lid 11 inner peripheral surfaces, in the present embodiment, this elastic component 323 is Compress Spring.

This rotating shaft 31 is divided into mutually disconnected first a chamber section 114 and second a chamber section 115 with this separation group 32 with this room 111.

This first chamber section 114 is communicated with this first flow 113, and this second chamber section 115 is communicated with this pod apertures 112.

Consult Fig. 2, Fig. 3 and Fig. 4, rotate this rocking handle 33 drive these rotating shafts 31 along a first direction R1 when self axis rotates, this separation group 32 can be by interlock and along with these rotating shaft 31 starts, and that described shim 321 can be subject to this elastic component 323 is butted and fit in this lid 11 inner peripheral surfaces, thereby increase gradually the volume of this first chamber section 114, and reduce the volume of this second chamber section 115, and then make this fluid (shown in arrow among Fig. 2 and Fig. 4) flow into this room 111 because this first chamber section 114 presses to change by this first flow 113 with the chamber of this second chamber section 115, and via these pod apertures 112 these filter chambers 121 of inflow, thereby the coarse filtration section 21 that enters this filter core 2 filters with this fine filtering section 22, and this fluid after the filtration will be flowed out in this housing unit 1 by this second runner 122.

It is worth mentioning that because filter core of the present utility model 2 adopts the design of tool filtering direction, preferably, the ratchet structure that can also add one way engagement can only rotate this rocking handle 33 along this first direction R1 with restriction.

But, when this filter core 2 is not had a filtering direction or when having rightabout, also can rotate this rocking handle 33 drives these rotating shafts 31 and rotates around self axis along one in contrast to the second direction R2 of this first direction R1, and drive this separation group 32 with the volume that reduces this first chamber section 114 and the volume that increases this second chamber section 115, and then make this fluid enter this this filter chamber 121 of filter core 2 rear inflows because the chamber pressure changes by this second runner 122, and flowed out in this housing unit 1 by this first flow 113 via this room 11.

By above composition, advantage of the present utility model and effect can be summarized as follows:

One, is installed on rotating shaft 31 in this room 111 by rotation, just can drive this separation and organize 32 starts, utilize this first chamber section 114 to press to change to reach with the chamber of this second chamber section 115 and take out the function of drawing this fluid, unidirectional complication system compared to known the utlity model has simplified structure, reduces part and dwindles the advantages such as overall volume.

Two, utilize this pump unit 3 can reach the function of two-way pump, can be used in neatly various occasions for different filtration needs and application target, also have the effect that increases product applying flexible degree.
