Description

A kind of half deserted filter element structure of water purifier

Technical field

A kind of water purifier is the utility model is related to, especially a kind of half deserted filter element structure of water purifier.

Background technology

As the improvement of people's living standards, people gradually step up to the quality requirement of drinking water, the quality of water is directly closed It is the health to human body.

In order to obtain clean drinking water, occur many water purifiers now, these water purifiers generally by filter core, filter housing and Upper lid is formed, and filter core is wrapped in filter housing, and upper lid is arranged at the top of filter housing, after long-time uses or filter core fails, by upper lid Taken apart with filter housing, filter core is taken out and changed.It is a kind of as disclosed in the Chinese patent of Application No. 200910034256.3 Water purification catridge, including housing, hollow fiber film assembly and sorbing material layer, housing are made up of upper shell and lower house, hollow fibre Dimension membrane module is located at centre position in housing, and sorbing material layer is located on the water inlet of housing and hollow fiber film assembly Under entrance and around the space being full of between housing and hollow fiber film assembly, when the hollow fiber membrane surface covering in filter core When having the adsorbent failure in more dirt or adsorption piece, filter core upper shell and lower house can also be turned on, can be by adsorption piece Replacing is taken out, hollow fiber film assembly cleaning can be taken out after taking out adsorption piece；And for example Application No. 201620101562.X Chinese patent disclosed in a kind of filter core, including casing assembly and filter element body, casing assembly include filter core bucket and filter element upper cover, Filter core bucket is removably mounted on filter core bucket in open upper end and the tubbiness of lower end closed, filter element upper cover, filter element upper cover installation The open end of filter core bucket to be closed when on filter core bucket and limits filter space, filter element body can be arranged in filter space, when When need to change filter core, whole filter core can need not be changed, and only needs to disassemble filter element upper cover from filter core bucket, takes out filter core sheet Body, then new filter element body is arranged in filter core bucket, and filter element upper cover lid is located on filter core bucket and closes filter space, you can Complete the replacing of filter core.

These above-mentioned half deserted filter element of water purifier, when changing core, inner core is only changed, retains filter housing, filter housing is through long The work of time, has been heavily polluted, and is difficult to clean up although can be cleaned when core is changed.Therefore it is net The filter core that hydrophone is newly changed is not started working also and has just been contaminated, and so brings hidden danger to filter element filtering effect；And if Filter housing is changed while filter core is changed, then can be caused not environmentally, in particular for short using replacement cycles such as PP cottons, activated carbons Filter core.

Utility model content

Technical problem to be solved in the utility model is in view of the above-mentioned problems of the prior art, providing a kind of improve Filter housing cleannes, the half deserted filter element structure of water purifier for avoiding secondary pollution.

Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of half deserted filter element of water purifier knot Structure, including filter housing exist with its components being arranged in filter housing, inner core of its components including being used for water purification, its feature In：The inner core periphery is provided with the film shell of tubular, and the film shell will be isolated by the water route of inner core and filter housing.

Further, for ease of water route and filter housing are isolated, the first joint, the filter housing bottom are provided with the top of the filter housing The second joint is provided with portion, the first end cap being connected with the first joint, the inner core are provided with the top of its components The bottom of component is provided with the second end cap of closing, and the 3rd end being connected with the second joint is provided with below second end cap Lid.

Further, for ease of water route and filter housing are isolated, the upper end of the film shell is fixed with the first end cap, described thin The lower end of putamina is fixed with the 3rd end cap.

Preferably, the film shell and the first end cap, the second end cap are respectively adopted ultrasonic bonding and fixed.

Further, to avoid long-time rear film shell breed bacteria from polluting inner core, the film shell, which uses, to be added It is made added with the food-grade PE of antibacterial material.

Compared with prior art, the utility model has the advantage of：By setting the film shell for isolating filter housing and water route, So that film shell contacts with current, and filter housing only undertakes the effect of pressure-bearing, so as to change filter housing when changing core, saves material Material, avoids causing secondary pollution to current.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

Referring to Fig. 1~Fig. 5, a kind of half deserted filter element structure of water purifier, including filter housing 1, the inner core that is arranged in filter housing 1 Component 2 and the first joint 3 for being arranged on the top of filter housing 1.First joint 3 is used to filter cartridge construction and water source being attached, its It can be connected with the screw top of filter housing 1.

Its components 2 include inner core 21, the first end cap 22, the second end cap 23, the 3rd end cap 24 and film shell 25.Inner core 21 Such as can be PP cottons, activated carbon for being filtered to the water of entrance.First end cap 22 and the second end cap 23 are separately positioned on The upper/lower terminal of inner core 21.First end cap 23 is used to its components 2 are in fluid communication with the first joint 3, and the second end cap 23 Lower section is additionally provided with the 3rd above-mentioned end cap 24, and the second joint 11 is provided with the bottom of filter housing 1, and the 3rd end cap 24 is used to make Obtain its components 2 and the second joint 11 of the bottom of filter housing 1 is in fluid communication.

Film shell 25 is cylindrical in shape, and is arranged on the periphery of inner core 21, so as to be isolated by the water route of inner core 21 and filter housing 1, Filter housing 1 is avoided to touch water.The upper end of film shell 25 is fixed with the first end cap 22, and the lower end of film shell 25 is solid with the 3rd end cap 24 Fixed, fixed mode can use ultrasonic welding process, so that by the end cap 22 of film shell 25 and first, film shell 25 and the 3rd End cap 24 is separately fixed at together.Thus, inner core 21 is completely enclosed between the first end cap 22 and the 3rd end cap 24.Film shell 25 can be made of food-grade PE, to reduce film shell 25 after a certain period of use time to caused by inner core 21 and the current passed through Pollution, can add antibacterial material in PE.

Referring to the arrow in Fig. 5, the flow direction for filter core current at work that shows passes through from the first joint 3 The water that one end cap 22 enters, such as running water, is filtered by inner core 2, due to the bottom of the second end cap 23 closing inner core 21 so that Perisporium of the current direction periphery along film shell 25 and is discharged to flowing down by the second joint 11 of the 3rd end cap 23 and filter housing 1. During this, film shell 25 is contacted with by the current of inner core 21 instead of filter housing 1, and filter housing 1 then not with the water by inner core 21 Stream contact, only undertakes pressure-bearing function.

, can be by the integral replacing of its components 2 when needing to change filter core, and filter housing 1 need not be changed, and due to filter housing 1 Do not contacted in use with current, therefore secondary pollution will not be also caused even if filter housing 1 is changed without, inner core group can be improved The filter effect of part 2.
