Description

A kind of fast disassembly type filter core capable of washing

Technical field

The present invention relates to water purifier filter core field more particularly to a kind of fast disassembly type filter cores capable of washing.

Background technique

Filter core used in existing water purifier is all outer cylinder and the filter assemblies composition that outer cylinder is arranged in, and filter assemblies is placed in outer Outer cylinder is integrally formed using thermoplastic processes after in cylinder, filter core is made into disposable products to reach good water-stop effect.

Existing filter assemblies are typically all to use filtrate, active carbon and the one such or a variety of combination of PP cotton. In addition, in order to obtain the water of high-quality, filter assemblies generally comprise the filter material layer, active carbon layer and PP set gradually from inside to outside Cotton layer.

Such filter assemblies, on the one hand, since the PP cotton filter element service life is 6 months, and active carbon filter core is 12 months, because Under normal circumstances for two kinds of materials, it using the time for reaching the service life at first as replacing construction, since filter core is integral type product, uses The filter core that family can only more renew uses, therefore 12 months service life of script active carbon were shorter by 6 months；On the other hand, outer cylinder is PC material, service life are 1 year or more, and the design of integrated filter core also virtually reduces the service life of outer cylinder.

Summary of the invention

To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of fast disassembly type filter core capable of washing, the filter core it is outer Cylinder is that detachable design can quickly split out filter assemblies while guaranteeing water-stop, is carried out to filter assemblies quick Cleaning and replacement.

To achieve the above object, the invention adopts the following technical scheme:

Specific embodiment

The present invention is described in further details below in conjunction with the drawings and specific embodiments:

As shown in Figure 1 to Figure 3, a kind of fast disassembly type filter core capable of washing, including outer cylinder and the filter assemblies being arranged in outer cylinder 1；

The outer cylinder includes cylinder 2 and the cover 3 that is detachably connected on cylinder 2；

2 lower part of cylinder is provided with bulge loop 21, and bulge loop 21 plays position-limiting action to entire cover 3, and to outer cylinder and cylinder Lid plays the role of tentatively sealing.It is arranged fluted 22 in the lower section of bulge loop 21, in the top of the bulge loop 21 or bulge loop 21 It is provided with card slot 23, in the present embodiment, is uniformly arranged that there are four card slots 23 on bulge loop 21.

The lower outside of the cylinder 2 is provided with sealing ring 34, and the lower section of groove 22 is arranged in sealing ring 34, it is preferred that The Basolateral of cylinder 2 is arranged in sealing ring 34；Further, as shown in figure 4, being provided with an annular in the sealing ring 34 The seal chamber 341 of labyrinth type, sealing ring 34 are provided with communicating pipe 342 outside, communicating pipe 342 are connected to outer cylinder and filtering by a channel Intake antrum between component 1；In intake antrum when water inlet, internal pressure is increased, and water is entered in sealing ring 34 by communicating pipe 342 Seal chamber 341 increase the expansion of sealing ring 34, generation throttle effect reaches Drain Resistance when water passes through the gap in tortuous labyrinth Purpose reinforces sealing function；When disassembly, cleaning filter assemblies 1, water is discharged, the water in the seal chamber 341 of sealing ring 34 can pass through Communicating pipe 342 flows out, and sealing ring 34 reduces, convenient for the disassembly of cylinder 2 and cover 3.

The cover 3 includes cutting ferrule 31 and is movably set in the lock tube 32 that can freely up and down move on cutting ferrule 31；The card Set 31 on be provided with groove 22 cooperate ball 33, ball 33 cutting ferrule 31 radially have certain free travel, i.e., Offset can be radially controlled in cutting ferrule 31；Specifically, being uniformly arranged on the cutting ferrule 31 of annular, there are four stroke holes (in figure It is not shown), stroke hole is embedded to be cased with four balls 33, and the partial size for the ball 33 that the aperture in stroke hole is slightly larger than, stroke hole both limited Made the position of ball 33, but guarantee ball 33 can in stroke hole radial deflection.

The top of the lock tube 32 is provided with the fastener 321 cooperated with card slot 23, in the present embodiment, annular lock tube 32 Top be uniformly arranged there are four fastener 321, cooperate respectively with the card slot 23 of cylinder 2；The lower part of lock tube 32 is provided with to hold The grip part 322 held.

Elastic component 35 is provided between the lock tube 32 and cutting ferrule 31, lock tube 32 can make ball 33 inside by elastic component 35 It rolls and engages ball 33 closely with groove 22, in the present embodiment, the elastic component 35 is spring.By grip part 322 to Lower slider lock tube 32 makes ball 33 be in free state, and cylinder 2 can cover in lock tube 32, pushes down on cylinder 2 up to cylinder 2 Groove 22 reaches at the ball 33 of cutting ferrule 31, and sliding lock set 32, lock tube 32 promote ball 33 to move inward, make lock tube then up 32 entire cards reach preload effect in groove 22, to lock tube 32 and cylinder 2, then rotate lock tube 32, the fastener of lock tube 32 again 321 are caught in the card slot 23 of cylinder 2, fixed lock tube 32 and cylinder 2.When opening outer cylinder, needs first to rotate lock tube 32, make fastener 321 are detached from card slot 23, then sliding lock set 32, make ball 33 again in free state, then in extraction cylinder 2, pass through two The operation of step can be such that cylinder 2 separates with cover 3, prevent old man or the direct down operation of child, accidentally open outer cylinder, cause Water in filter core sprays.

The filter assemblies 1 include filter material layer 11, filter bed of essence 12 and the coarse filtration layer 13 set gradually from inside to outside, the filter The bed of material 11 and the non-dismountable connection of filter bed of essence 12, the coarse filtration layer 13 are detachably connected on outside filter bed of essence 12, the coarse filtration layer 13 It is made of multilayer sublayer, the inner and outer wall of every sublayer is provided with connection screw thread；In the present embodiment, the filter bed of essence 12 is Active carbon layer, the filter bed of essence 12 are PP cotton layer, and the coarse filtration layer 13 includes multilayer PP cotton layer, and PP cotton layer inner and outer wall is all provided with It is equipped with connection screw thread.

When the filter core needs to clean filter assemblies 1 when using by 6 months, internal water is emptied, rotates cover 3, and downwards Sliding lock set 32 dismantles cover 3, splits out filter assemblies 1, using ultrasonic wave or high-pressure cleaning device cleaning PP cotton layer, if clearly It is undesirable to wash effect, PP cotton layer outside replaceable.

The foregoing is merely a specific embodiment of the invention, are not intended to limit the scope of the invention, all benefits The equivalent structure transformation made by description of the invention and accompanying drawing content is applied directly or indirectly in other relevant technology necks Domain is included within the scope of the present invention.
