Abstract

The utility model discloses a filter, comprising a filter vat, a cylinder, a piston and a filter layer. A water inlet is arranged at the bottom end surface of the filter vat and a check valve is arranged at the water inlet. The filter layer is located in the filter vat and the cross section of the filter layer is same with that of the inner cavity of the filter vat in size. The piston is located in the filter vat and placed above the filter layer. The cross section of the piston is same with that of the inner cavity of the filter vat in size. The piston is sealed by a sealing ring. The piston is provided with a through hole which communicates the upper and lower spaces of the filter vat separated by the piston. A stopping structure that prevents water from flowing back from the upper part of the piston to the lower part of the piston is arranged on the through hole. A connecting rod of the cylinder penetrates through the top end surface of the filter vat and is connected with the piston. The filter layer at least comprises a filter screen layer and an active carbon layer. A water outlet is arranged above the filter vat. The filter provided by the utility model has a simple structure, is simple to operate and labor saving and can be used by many people, thereby, the filter is an indispensable device for people attending outdoor activities and ensures that people can drink water safely when emergency happens.

Description

A kind of filter

Technical field

The utility model relates to a kind of open-air convenient and fast filter that is applicable to.

Background technology

Along with the continuous aggravation of environmental pollution, people often are difficult to find the water source of quoting of cleaning in outdoor sports such as tourism, field construction, march, exploration, very inconvenience.Municipal water facilities is perhaps thought in war, malignant pollution accident etc. in natural calamities such as experience earthquake, tsunami, floods disaster can't provide the water supply of cleaning in a short time to the resident.At present in face of natural calamities such as earthquake, tsunami, flood; The government that has has to use the mode of helicopter air-drop pure water to the victims of the disaster water to be provided; Therefore, people need a kind of portable, can help people to tackle the purifier of the water supply crisis of various bursts.

The utility model content

Goal of the invention: in order to overcome the deficiency that exists in the prior art, it is a kind of portable that the utility model provides, and can help people to tackle the filter of the water supply crisis of various bursts.

Technical scheme: for solving the problems of the technologies described above, the technical scheme of the utility model sampling is:

A kind of filter comprises filter vat, cylinder, piston, filter course, is provided with water inlet at the bottom face of filter vat, is provided with check valve in the water inlet; Filter course is positioned at filter vat, and its cross section and filter vat inner chamber shape of cross section are measure-alike; Piston is positioned at filter vat; Place the top of filter course; The cross section of piston and filter vat inner chamber shape of cross section are measure-alike; And, on piston, be provided with filter vat that connection separated by the piston through hole in space up and down through sealing ring sealing, flow back to the non-return structure below the piston above the piston being provided with anti-sealing on the through hole; The top end face that the connecting rod of cylinder passes filter vat is connected with piston; Said filter course comprises filter mesh layer and active carbon layer at least; Above the side of filter vat, be provided with delivery port.

After water got into from water inlet, through the reciprocating motion of cylinder and the control of check valve, water was inhaled into filter vat, and passes the through hole on filter course and the piston, flows out delivery port.

Beneficial effect: the filter that the utility model provides, simple in structure, simple to operate laborsaving, can supply many people to use, be the outdoorsman indispensable devices of the people, in the time of can guaranteeing people's solution of emergent event, safty of drinking water.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done explanation further.

Be depicted as a kind of filter like accompanying drawing 1, comprise filter vat 3, cylinder 7, piston 5, filter course 11, be provided with water inlet 1 at the bottom face of filter vat 3,1 place is provided with check valve 2 at water inlet; Filter course 11 is positioned at filter vat 3, and its cross section and filter vat 3 inner chamber shape of cross sections are measure-alike; Piston 5 is positioned at filter vat 3; Place the top of filter course 11; The cross section of piston 5 and filter vat 3 inner chamber shape of cross sections are measure-alike; And, on piston 5, be provided with the through hole 10 in filter vat space 3 about that connection separated by piston 5 through sealing ring 4 sealing, prevent that sealing flows back to the non-return structure 12 below the piston 5 above the piston 5 being provided with on the through hole 10; The top end face that the connecting rod of cylinder 7 passes filter vat 3 is connected with piston 5; Said filter course 11 comprises filter mesh layer and active carbon layer at least; Above the side of filter vat 3, be provided with and blow the mouth of a river 9.

The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
