Abstract
The utility model provides a support-free filtering device, which is characterized in that the filtering device is formed by an upper layer of filtration permeable materials and a lower layer of filtration permeable materials, activated carbon felts or activated carbon fibers are attached between the two layers of the filtration permeable materials, and the rim of the filtering device is formed by ultrasonic treatment. The filtering device has the advantages of simple structure, convenient use and low production and assembly costs.
Description
Technical field
The utility model relates to the utensil that is used for filter liquide, relates to a kind of filter of exempting from support particularly.
Background technology
Existing filter generally comprises filter core and filter holder, filter holder is fixedly mounted in the equipment that need filter, because filter need be changed or be cleaned in use for some time, so need filter holder together to be disassembled replacing or clean, thereby use the production maintenance cost height of inconvenience and product.
Existing material for core commonly used has: the grains of sand, medical stone, filter paper and active carbon etc., wherein active carbon not only can filter micro dust particle, also has deodorizing, the effect of sterilization, thereby be widely used in filtering in the utensil, existing filter such as the patent 200720127817.0 that adopts activated carbon felt or NACF, its structure chart is referring to accompanying drawing 1, on activated carbon felt or NACF the upper surface or lower surface attached to the saturating property material of filter, and then filter property material is fixed in the bracing frame, be provided with groove in the bracing frame, realize seamless the connection by groove with the saturating property edge of materials of filter, to prevent that activated carbon felt or NACF break away from, its shortcoming is the support frame structure complexity, production assembly cost height.
The utility model content
The utility model is the shortcoming that overcomes above-mentioned existing filter, and a kind of support filter of exempting from is provided.
The utility model realizes that the technical scheme that goal of the invention adopts is: a kind of support filter of exempting from, described filter is made up of the saturating property of two metafiltration material up and down, be attached with activated carbon felt or NACF between the saturating property of the described two metafiltration material, the peripheral part of described filter is bonded to compact texture.
Better, the peripheral part of described filter is bonded to compact texture through ultrasonic processing.
Better, the peripheral part of described filter also can be bonded to compact texture by glue.
Better, the saturating property of described filter material is filter paper or filter cotton or nonwoven.
Better, the saturating property of described filter material is a degradable plant fiber.
Better, described filter is circular or square.
The beneficial effects of the utility model are: simple in structure, easy to use, the production assembly cost is low.
Description of drawings
The structure chart of Fig. 1, existing filter.
Fig. 2, structure chart of the present utility model.
Among the figure, the saturating property material of 1 filter, 2 activated carbon felts or NACF layer, 3 peripheral bonding parts.
The specific embodiment
Referring to accompanying drawing 2, a kind of support filter of exempting from, comprise the saturating property material 1 of two-layer circular filter, activated carbon felt or NACF layer 2, peripheral bonding part 3, described activated carbon felt or NACF are attached between the two-layer nonwoven 1, and described peripheral bonding part 3 forms through ultrasonic processing bonding.
According to application need, the saturating property of described filter material 1 can adopt nonwoven or filter paper or filter cotton, based on requirement on environmental protection, also can adopt degradation material fibre and soya, zein fiber etc. as the saturating property material 1 of filter.
This is exempted from the support filter and can be applicable to the coffee machine filtration, directly filter is fixed on coffee machine during use and filters mouth, because the saturating property material of filter itself has mechanical strength preferably, the whole filter in fixing back can bear bigger pressure, simultaneously, because the filter periphery has passed through ultrasonic bonding, can prevent effectively that activated carbon felt or NACF from taking place to slide and break away from, both guaranteed that mid portion activated carbon felt or NACF had the saturating property of loose preferably filter, can guarantee the isolation of whole filter again, prevent that outside micronic dust from entering the active carbon filtering layer.
The described support filter of exempting from of present embodiment also can be applicable to as in the food-grade filters such as making tea machine, domestic filtered device, and not only filter property well can effectively be adsorbed again and removed various impurity, has advantages such as nontoxic, environmental protection, production cost be low.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, it will be understood by those of skill in the art that still and can make amendment or be equal to replacement the utility model although this specification has been described in detail the utility model with reference to each above-mentioned embodiment; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (6)
1. exempt from the support filter for one kind, it is characterized in that: described filter is made up of the saturating property of two metafiltration material up and down, is attached with activated carbon felt or NACF between the saturating property of the described two metafiltration material, and the peripheral part of described filter is bonded to compact texture.
2. a kind of support filter of exempting from according to claim 1, it is characterized in that: the peripheral part of described filter is bonded to compact texture through ultrasonic processing.
