Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
Please refer to Fig. 1, Fig. 1 be one of the present invention preferred embodiment, this irrigator comprises top cover 1, base 3, top cover 1 is provided with water inlet 102, base 3 is provided with runner, filter element group is provided with between top cover 1 and base 3, in this embodiment, filter element group comprises 3 pieces of filter elements 2, and the shape of this filter element 2 and the mating shapes of top cover 1 and base 3, each filter element 2 is provided with the filter bores 4 of some, the material of filter element 2 is water swelling rubber (WSR), and expansion rate of water absorption is 40%-70%.
Filter element 2, when processing, is first pressed clockwise or counterclockwise, processes filter bores, then cut out the size of filter element 2 according to actual needs with arbitrarily angled on bulk water swelling rubber.Time some filter elements 2 superposes and forms filter element group, can ensure that filter bores 4 on adjacent filter elements 2 is random and be overlapping together.
Filter bores 4 is communicated with by the hole of some the polygonal formed successively, and shown in Fig. 5 is a kind of embodiment of filter bores 4, and its polygonal filter bores formed comprises 7 angles, and the angle at each angle is 30 °.In figure, dash area is depicted as the net shape of filter bores 4, and each hole all has one fixed width, and each bar hole head and the tail are communicated with, and form polygonal Openworks shape.
In a preferred embodiment, the head and the tail of initial hole 401 and terminal hole 402 do not connect.
This irrigator is that interior edge is SMD, during use, it is bonded in hollow billet inwall by hot melting cohesion technique, and the course of work of this irrigator is:
Start drip irrigation system, irrigation water enters in drip irrigation pipe, by water inlet and the filter element comes in contact of top cover, filter element is made up of water swelling rubber (WSR), when WSR contacts with water, hydrone can by diffusion, the physical action such as capillary and adsorption enters in WSR, and then form extremely strong affinity with the hydroaropic substance (group) in rubber, hydroaropic substance constantly absorbs water, cause rubber generation deformation, when resistance to deformation power and permeable pressure head reach balance, keep relative stability, when the imbibition of filter element group and top cover, base inner wall fits tightly, play the effect of sealing, simultaneously filter element obtains reaction force resistance to deformation that irrigator inwall and each element provide mutually and inwardly extrudes, polygonal filter bores on such filter element expands at material self and deforms under mutual squeezing action, pore shape and size change, size significantly reduces, transfer of shapes is layer after layer gap, such filter element becomes miniature well strainer, play the effect of end-filtration.Therefore, because filtering not thorough, the impurity such as organic matter, inorganic matter, microorganism (as algae, bacterium) entered in drip irrigation pipe can be increased substantially by the dimensional requirement of end-filtration element, the corresponding decline of the possibility that results in blockage on the one hand; On the other hand, when due to system Long-Time Service, the intrapore impurity of filtration being attached to filter element group increases gradually, causes filter bores to block, block even completely when the filtration hole blocked is more and more, be reduced to no longer water outlet by filtration hole by the water of irrigator.Now filter element group release water (after irrigator placement certain hour), distortion retraction, pore-size increases, and impurity is washed away outflow irrigator by pressure water, and irrigator recovers normally work.
In a kind of embodiment be more preferably, the conveniently assembling of irrigator each several part, top cover 1 is provided with socket 101, filter element 2 is arranged the trepanning 201 matched with socket, base 3 is provided with the plug 301 matched with socket 101 and trepanning 201, three is plugged in together.
In a kind of embodiment be more preferably, the runner on base 3 is divided into inner flow passage and outer flow passage, and near filter element 4 side is inner flow passage 5, and what be positioned at inner flow passage opposite side is outer flow passage 6, is communicated with therebetween by a communicating passage 302.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
