Abstract
A sealing cover for filtering element mainly comprises a seal gasket and a plastic ring and is characterized in that: the bottom end of the seal gasket is provided with an inner lip rim and a groove beneficial to compression deformation; the plastic ring is provided with an outer lip rim and a member propping up against the seal gasket; the inner lip rim of the seal gasket and the outer lip rim of the plastic ring form a corresponding groove embedded into the top end of a filtering element with the outer lip rim of the plastic ring adhered to the filtering element, thereby a rubber gasket, the plastic ring and the filtering element are combined together. Through adopting the product, filtering elements of identical specification and axial size can be used in water purifier of different specifications, and the seal gasket can not fall into filtering machine.
Description
The utility model relates to the filter core fixed part of water purifier, refers to a kind of filter core seal cover that can enlarge filter core axial dimension range of application especially.
The present water purifier that uses, the seal cover bottom surface on its filter core is the plane, does not have elasticity after being fastened on the filter core, in case the size of water purifier changes slightly, just must select else and purchase filter core and supporting with it seal cover, causes waste economically.Such as: the specification of the water purifier that hospital's haemodialysis is used has multiple, the size of import water purifier has 245mm-254mm, homemade 242mm and 250mm is arranged, because the difference of water purifier specification, select filter core to bring many troubles to the user, the choosing of filter core size is long, and the water purifier body seal is bad to leak, and the choosing of filter core size is short, cause by the short circuit of filtrate body, do not reach filter effect; And after filter core used, when renew cartridge, seal cover often dropped in the filter, results in hand cramps to work.
The purpose of this utility model be to provide a kind of can finely tune the filter core axial dimension, it can be long because of filter core size choosing, seal bad leaking; Can be not short because of the choosing of filter core size yet, cause by the filter core seal cover of filtrate body short circuit.
The purpose of this utility model also is: after providing a kind of filter core to use, when renew cartridge, seal cover can not drop in the filter, thus the filter core seal cover that makes troubles to work.
The purpose of this utility model is achieved in that a kind of filter core seal cover, mainly comprise sealing gasket, plastic ring, it is characterized in that: the sealing gasket bottom is provided with the epipharynx limit and is beneficial to the groove of compression, plastic ring is to have the outer lip limit and be pressed on member on the sealing gasket, the epipharynx limit of sealing gasket and the outer lip limit of plastic ring formation one are embedded in the respective slot on filter core top, and the outer lip limit of plastic ring is bonded on the filter core, makes rubber blanket, plastic ring, filter core triplicity together.
The utility model also can be realized by following technical measures: described sealing gasket is the rubber with big compression ratio; Described plastic ring is the duroplasts goods that cross section is the Г type.
Concrete structure of the present utility model is described further by following examples and accompanying drawing:
Fig. 1, be schematic sectional view of the present utility model.
Fig. 2, be vertical view of the present utility model.
Referring to Fig. 1,2, a kind of filter core seal cover mainly is made up of sealing gasket 1, plastic ring 3 two parts; Wherein sealing gasket 1 is the rubber with big compression ratio, and the bottom is provided with epipharynx limit 5 and is beneficial to the groove 2 of compression, but the axial dimension of sealing gasket 1 is pressed filter core 4 axial dimension mark shelves, as: 250mm, 254mm etc., to enlarge the range of application of filter core 4.
Advantage of the present utility model is: because the baseplane of rubber blanket 1 is provided with a circle groove 2, can enlarge the scope of application of filter core axial dimension, increase the elasticity of filter core axial dimension, so a kind of filter core 4 of size is applicable to the water purifier of several different specification sizes, for example: the filter core of 246mm is applicable to the water purifier of 242mm-246mm specification, the filter core of 250mm is applicable to the water purifier of 246mm-250mm specification, and the filter core of 254mm is applicable to the water purifier of 250mm-254mm specification.
Again because this filter core seal cover, after adopting plastic ring 3 that rubber blanket 1 is pushed down, plastic ring 3 and filter core 4 are bonded as the characteristics of one, the trouble of having avoided rubber blanket 1 to drop and salvage rubber blanket 1 in filter, and overall appearance is attractive in appearance, extremely agent's favor.
Claims (3)
1, a kind of filter core seal cover, mainly comprise sealing gasket, plastic ring, it is characterized in that: the sealing gasket bottom is provided with the epipharynx limit and is beneficial to the groove of compression, plastic ring is to have the outer lip limit and be pressed on member on the sealing gasket, the epipharynx limit of sealing gasket and the outer lip limit of plastic ring formation one are embedded in the respective slot on filter core top, and the outer lip limit of plastic ring is bonded on the filter core, makes rubber blanket, plastic ring, filter core triplicity together.
2, filter core seal cover according to claim 1 is characterized in that: described sealing gasket is the rubber with big compression ratio.
