On the other hand, fixed as described above, hollow fiber membrane bundle 10 is bent to U-shaped by generally hollow Fibrous membrane filtration core
The both ends of the hollow fiber membrane bundle 10 and bonding paste first top cover 110 after bonding, thus in completing on cut surface
Empty fiber membrane filtration core.
Here, traditional way mainly uses adhesive, such as polyurethane binder, pastes the first top cover 110, then uses
Supercritical ultrasonics technology is pasted.
In this case, the risk that the impacts such as vibration cause hollow-fibre membrane to rupture caused by ultrasonic wave is higher, if not
The careful binder amount used is too many, then the adhesive blocking that the stomata of hollow fiber membrane bundle 10 may can outflow.Separately
Outside, in order to prevent this problem and when using a small amount of amount of binder, then first top cover 110 cannot be enough strong
The lower bonding of degree, occurs leak when to being likely to result in using hollow-fibre membrane filtration core.
Therefore, the present invention provides a kind of technical ideas, i.e., make hollow fiber membrane bundle 10 and outer by the adhesive portion 200
Shell 100 is bonded with polyurethane binder simultaneously, while making in the adhesive portion 200 shell 100 and hollow fiber membrane bundle 10
Both ends are physically separated, so as to thoroughly prevent polyurethane binder from infiltrating through 10 side of hollow fiber membrane bundle.
According to one embodiment, first top cover 110 may include that end is bent to the shell 100 and is formed outer
Side fixed part is separated by the inside fixed part for being formed in 110 inside of the first top cover of pre-determined distance with the outside fixed part
111,
Also, using the space between the outside fixed part and inside fixed part 111, it can operate and complete the shell
Engagement (bonding) between 100 and the adhesive portion 200.For example, can be in the outside fixed part and the inside fixed part
Space coating between 111 can make to fix positioned at the outside for being bonded the adhesive 30 of first top cover 110
The medial surface of first top cover 110 in space between portion and inside fixed part 111 and the part side of the adhesive portion 200
Face can be bonded, combine.
The outside fixed part is fitted closely with the side of the shell 100 or the side surface part of the adhesive portion 200, with institute
The engagement of the first top cover 110 is stated, at this point, the inside fixed part 111 is inserted into the adhesive portion 200, first top can be made
The engagement of lid 110 is stronger.This example is as shown in Figure 2.
Fig. 2 is the explanatory diagram of the top cover connected structure for the Water purifier filter core that one embodiment of the present of invention is related to.
With reference to Fig. 2, groove 210 can be formed in the adhesive portion 200.
When first top cover 110 engagement, the groove 210 may be formed at corresponding with the inside fixed part 111
Position, when first top cover 110 engagement after, the inside fixed part 111 can be plugged into the groove 210.
Also, the medial surface of the inside fixed part 111, i.e., between the described outside fixed part and the interior fixed part 111
Space in coating adhesive 30, make the shell 100 being located in the space and first top cover 110 or described
A part of adhesive portion 200 is Nian Jie with first top cover 110.According to embodiment, the shell 100 and the adhesive portion 200
A part can also be Nian Jie with first top cover 110.
In view of this, the beneficial effect when forming inside fixed part 111 in first top cover 110 is: first top cover
110 by the engagement of spaces between outside fixed part and the inside fixed part 111, is coated with adhesive 30 within this space not
The other parts of the adhesive portion 200 can be leaked into, that is, the fixed part in end of the hollow fiber membrane bundle 10, thus
It can fundamentally prevent the hollow fiber membrane bundle 10 from being blocked by described adhesive 30, the water purification flow path 60 can also be prevented
The water purification 21 of middle flowing is polluted by adhesive 30.
On the other hand, according to another embodiment of the invention, when engaging first top cover 110, O can also be used
Shape ring combines.As shown in Figure 3.
Fig. 3 is the signal of the top cover connected structure for the Water purifier filter core being related to according to another embodiment of the invention
Figure.
With reference to Fig. 3, the Water purifier filter core 1 that another embodiment of the invention is related to substantially can have and scheme before
1 described constitutes identical configuration.
