Description
Technical field
The utility model belongs to a kind of drinking-water apparatus, especially refer to a kind of in water tumbler the filter of filtering tea or coffee.
Background technology
After in make tea device or coffee pot, adding tealeaves or coffee bean, put into filter, pour boiling water then because the filtration of filter, make we drink Shi Buhui with tealeaves or coffee grain drink inlet in.Existing a kind of water tumbler filter comprises circular screen pack, goes up compressing tablet, lower sheeting, cushion rubber and pull bar, and last compressing tablet and lower sheeting are clipped in the middle screen pack regularly, and cushion rubber is positioned at the excircle of compressing tablet and lower sheeting.The filter effect of this filter is better, and still, if when the water tumbler internal diameter has fine difference in the vertical, there are some difficulties in cushion rubber with cooperating of wall of cup.
The utility model content
A purpose of the present utility model is to solve weak point of the prior art, and a kind of filter that better cooperates with the water tumbler inwall that has is provided.
For achieving the above object, water tumbler filter of the present utility model comprises compressing tablet, lower sheeting, screen pack and pull bar, screen pack is between last compressing tablet and lower sheeting, also be provided with silica gel circle and plastic tube between last compressing tablet and lower sheeting, plastic tube is positioned at the periphery of silica gel circle, and the circle body of plastic tube has fracture, one end of fracture is provided with the fluting of strip, the other end of fracture is provided with and the corresponding protuberance of slotting, and protuberance is arranged in fluting, and the thickness of plastic tube is less than the thickness of silica gel circle.
Preferably, the inside circumference of plastic tube is provided with a plurality of gap.
Preferably, described gap evenly distributes along inside circumference.
The utility model is simple in structure, and outward appearance is beautiful, and when there was minor variations in the water tumbler internal diameter, filter had preferably with the water tumbler inwall and cooperates.

The specific embodiment
Fig. 1 is the parts view sub-anatomy of water tumbler filter described in the utility model, and with reference to Fig. 1, water tumbler filter of the present utility model comprises circular screen pack 1, goes up compressing tablet 2, lower sheeting 3, silica gel circle 4, plastic tube 5, swivel nut 6, nut 7 and pull bar 8.Nut 7 passes the center of compressing tablet 2, lower sheeting 3 and filter screen 1, and pull bar is threaded with swivel nut 6 and nut 7.Last compressing tablet 2 and lower sheeting 3 are clipped in the middle screen pack 1, silica gel circle 4 and plastic tube 5.Screen pack 1 is positioned at the below of silica gel circle 4 and plastic tube 5, has a circle first boss 21 in the bottom of last compressing tablet, and the silica gel snare is in the periphery of first boss 21, and plastic tube 5 is positioned at the periphery of silica gel circle 4.Referring to Fig. 2, screen pack 1 also can be positioned at the top of silica gel circle 4 and plastic tube 5, at this moment, has a circle second boss 31 on the top of lower sheeting, and the silica gel snare is in the periphery of second boss 31, and plastic tube 5 is positioned at the periphery of silica gel circle 4.
Fig. 3 looks perspective view for the master of water tumbler filter plastic tube described in the utility model.Fig. 4 is the vertical view of water tumbler filter plastic tube described in the utility model.With reference to Fig. 3 and Fig. 4, the circle body of plastic tube 5 has fracture, and an end of fracture is provided with the fluting 9 of strip, and the other end of fracture is provided with and the corresponding protuberance 10 of slotting, and protuberance 10 is arranged in fluting 9, and the thickness of plastic tube is less than the thickness of silica gel circle.The inside circumference of plastic tube is provided with a plurality of gap 11, and gap 11 evenly distributes along circle body.
When the water tumbler filter was placed in the water tumbler, the outer of plastic tube contacted with the water tumbler inwall.Because plastic tube has said structure, makes the diameter of plastic tube to change within the specific limits.When plastic tube when water tumbler inwall than minor diameter contacts, described protuberance 10 moves in fluting, and the plastic tube diameter is diminished.Gap 11 helps plastic tube and becomes big and diminish.
The utility model is simple in structure, and outward appearance is beautiful, and when there was minor variations in the water tumbler internal diameter, filter had preferably with the water tumbler inwall and cooperates.Has better filter effect.
