Description
Technical Field
The utility model belongs to the water purification field, in particular to a filter core improves structure for in water purifier.
Background
The most important part of water purification is exactly the filter core, the good or bad direct influence water purification effect of filter core, the filter core mainly includes the body, upper cover and lower cover, with regard to present filter core, its body is fixed through screw thread fastening connection and screw thread with the upper cover, upper cover and external cup base seal through ordinary O type circle simultaneously, it is exactly that the upper cover directly packs into the lower cover again, it prevents kick-backing not to set up the buckle, certain user demand can be satisfied to this kind of traditional filter core structure, but also there is great defect, the body is fixed with upper cover threaded connection and screw thread, the troublesome inefficiency is changed in the filter core dismantlement, it is inconvenient to use, ordinary O type circle is sealed, the magnitude of interference is difficult to control, the not good easy water that leaks of leakproofness, difficult piston extrusion water, upper cover and lower cover do not have the buckle to be connected, the filter core easily kick-back, the leak the yields is low.
The to-be-solved technical problem of the utility model is to provide a bump is connected with the draw-in groove cooperation, dismantles to change simple efficient, convenient to use, heterotypic O type circle leakproofness are good, the magnitude of interference is easily controlled and is difficult for leaking, be convenient for extrude water, take the difficult resilience of buckle filter core to leak, the filter core improvement structure that the yields is high.
SUMMERY OF THE UTILITY MODEL
For solving above-mentioned prior art threaded connection and the fixed filter core of spiro union dismantle change troublesome inefficiency, use inconvenient, ordinary O type circle sealing magnitude of interference is wayward, the leakproofness is not good easily to leak, difficult piston extrusion goes out water, the upper cover does not have the buckle with the lower cover and is connected the easy resilience of filter core and leak, the yields hangs down the scheduling problem, the utility model discloses a following technical scheme:
the utility model provides a filter core improves structure, including body, filter core upper cover and filter core lower cover, the inboard bottom of body evenly is equipped with three spacing bump, the outside upside of filter core upper cover evenly is equipped with three spacing draw-in groove, spacing draw-in groove matches completely with spacing bump one-to-one and structure, position, size, filter core upper cover lower part has been seted up and has been placed the recess, it is provided with heterotypic O type circle in the recess to place, the transversal M shape of personally submitting of heterotypic O type circle, the filter core upper cover is connected with external cup base interference fit through heterotypic O type circle, filter core upper cover bottom evenly is equipped with the three buckle bump that prevents to kick-back, it has a plurality of to cross the water tank to cover under the filter core, the buckle bump matches completely.
The beneficial effects of the utility model reside in that: the body upper cover adopts bump and draw-in groove cooperation to be connected, dismantles and change simple efficient, convenient to use, heterotypic O type circle leakproofness is good, the magnitude of interference is easily controlled and is difficult for leaking, be convenient for extrude water, upper and lower lid is connected the difficult resilience of filter core through the buckle and is leaked, the yields is high.
Drawings
Fig. 1 is an exploded schematic view of an embodiment of the present invention.
Fig. 2 is a schematic view of the overall structure of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, an improved filter element structure comprises a body 1, an upper filter element cover 2 and a lower filter element cover 3, wherein three limit protrusions 11 are uniformly arranged at the bottom of the inner side of the body 1, three limit slots 21 are uniformly arranged at the upper side of the outer part of the upper filter element cover 2, the limit slots 21 and the limit protrusions 11 are in one-to-one correspondence, the structure, the position and the size are completely matched, the body and the upper cover are fixed through the protrusion slots, the disassembly and the replacement are simpler and more convenient, a placing groove is arranged at the lower part of the upper filter element cover 2, a special-shaped O-ring 22 is arranged in the placing groove, the cross section of the special-shaped O-ring 22 is M-shaped, the upper filter element cover 2 is in interference fit connection with an external cup base through the special-shaped O-ring 22, the interference of the special-shaped O-ring is easy to, it has a plurality of to cross water tank 31 to open on filter core lower cover 3, buckle bump 23 with cross water tank 31 complete matching, can prevent through the buckle bump that the filter core kick-backs and leaks.
The beneficial effects of the utility model reside in that: the body upper cover adopts bump and draw-in groove cooperation to be connected, dismantles and change simple efficient, convenient to use, heterotypic O type circle leakproofness is good, the magnitude of interference is easily controlled and is difficult for leaking, be convenient for extrude water, upper and lower lid is connected the difficult resilience of filter core through the buckle and is leaked, the yields is high.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
