Abstract
The utility model relates to a filter sealing structure which comprises a cover body, a filter casing arranged on the cover body and a filter core arranged in the filter casing; an elastic element and a piton connected with the elastic element are arranged in the cover body. The piston is composed of a water feeding piston and a water discharging piston, the water feeding piston is supported by the end part of the filter casing, and the water discharging piston is supported by head restraint at the end part of the filter core. When the filter core is installed, the filter casing and the filter core push the piston upwards, and the elastic element is compressed to conduct a water channel. When the filter core is detached, the piston moves downwards simultaneously under the actions of the elastic element and the water pressure to cause a sealing element on the piston to be compressed so that the water channel is broken. Thus, without shutting down the water supply of a water purifying device, water can not leak when the filter core is detached.
Description
Technical field
The utility model relates to a kind of water sealing structure of filter.
Background technology
Along with improving constantly of people's living standard, to the attention of health, people are also more and more higher to the requirement of drinking water, and the product of purifying waste water is subjected to consumers in general's approval gradually.The filter of establishing in the water purification product generally is made up of filter housing and filter core.When this filter needs more renew cartridge, must close the water source, turning on the nipple of filter and purifier dismantles filter housing, turn on lid older filter core is dismantled, replace with new filter core, tighten filter housing then, filter core is fixed, tighten the hickey of filter and purifier at last, could open the water source, make filter enter duty.Must close the water source earlier before this filter renew cartridge, stop the work of filter, after to be replaced the finishing, could open the water source, increased the more operating procedure of renew cartridge, and reduce the efficient that filter carries out tap water filter.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of good leak-proof effect is provided, simple in structure and also when renew cartridge more the water source can be in the water sealing structure of the filter of opening.
Goal of the invention of the present utility model is achieved in that a kind of water sealing structure of filter, comprises lid, is located at the filter housing on the lid and is installed on the interior filter core of filter housing, it is characterized in that: be provided with elastic component and the piston that is connected with elastic component in the described lid.
Described piston is water inlet plug and water outlet plug.
Described water inlet plug is by the filter housing end portion supports, and the water outlet plug is supported by the dop of filter core end.
Described water inlet plug and water outlet are provided with seal beyond the Great Wall.
Described elastic component is a spring.
The utility model improves the water sealing structure of the filter of prior art, is provided with elastic component in lid, and is provided with piston in the bottom of elastic component, and elastic component is connected with piston.Piston is made up of water inlet plug and water outlet plug, and the water inlet plug is by the filter housing end portion supports, and the water outlet plug is supported by the dop of filter core end.When loading onto the state of filter core, filter housing and the filter core jack-up piston plug that makes progress makes elastic component be in compressive state, makes the water route conducting.When pulling down the state of filter core, piston moves down under elastic component and hydraulic pressure effect simultaneously, makes the seal on the piston be in impaction state, and the water route disconnects.So just realized, when the dismounting filter core, need not close the water source of purifier, also do not had water and spill.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
With reference to the accompanying drawings shown in 1, the water sealing structure of filter of the present utility model, comprise lid 1, filter housing 2 and filter core 3, wherein lid 1 is provided with water inlet and delivery port, filter housing 2 is located on the lid 1, is provided with seal 7 in the junction of filter housing 2 and lid 1, and filter core 3 is installed in the filter housing 2, filter core 3 is provided with seal 7 equally with lid 1 junction, guaranteed the sealing that lid 1 and filter housing 2 are connected with filter core 3.Be provided with elastic component 4 in lid 1, this elastic component 4 is a spring.Elastic component 4 comprises into water elastic component and water outlet elastic component, also is provided with piston in the lid 1, and piston is made up of water inlet plug 5 and water outlet plug 6, and the water source flows to into water plug 5 and water outlet plug 6 from water inlet and the delivery port on the lid 1.Water inlet plug 5 is connected with filter housing 2 ends with the water inlet elastic component respectively, and water outlet plug 6 is connected with the dop of water outlet elastic component with filter core 3 ends respectively.Filter housing 2 is connected with elastic component 4 by the piston of establishing in the lid 1 with filter core 3.Be equipped with seal 7 on water inlet plug 5 and the water outlet plug 6, sealing part 7 can be made into sealing ring.
Under the state of loading onto filter core 3, filter housing 2 is jack-up water inlet plug 5 upwards, and the filter core 3 dops jack-up water outlet plug 6 that makes progress makes into that water spring, water outlet spring are in compressive state, and the water source circulation is freely suitable; Pulling down under the state of filter core, water inlet plug 5 is under the elastic force and hydraulic pressure effect of water inlet spring, and water outlet plug 6 simultaneously to bottom offset, makes the sealing ring 7 on into the water plug 5 and water outlet plug 6 be in impaction state under the elastic force and hydraulic pressure effect of water outlet spring, and the water source is fractureed.So just realized, when dismounting filter core 3, do not closed the water source of purifier, also drainage can not occur.The water sealing structure of filter of the present utility model by changing the internal structure of lid 1, does not more influence the normal operation of purifier renew cartridge 3 time.
