Description
Technical field
The utility model is related to stabilized pressure pump field, specifically a kind of pump head for improving water leak preventing structure.
Background technology
Currently, with the improvement of people ' s living standards, the development of water purification technology, water health has become heat of people's attention
Point, more and more water purifiers come into average family, critical component of the stabilized pressure pump as water purifier, but due to diaphragm and pump head
The connection sealing structure problem of lid is easy to user brings stabilized pressure pump to leak, service life is short, faults frequent puzzlement.
Utility model content
Utility model aims to solve above-mentioned existing problem, a kind of one kind simple and reasonable for structure is provided and is changed
Into the pump head of water leak preventing structure, effect is to solve the problems such as diaphragm is sealed with pump head lid.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of pump head improving water leak preventing structure, including pump head lid and bottom cover, coordinate successively between pump head lid and bottom cover
Flutter board, diaphragm, pump head seat and balance wheel seat are installed, it is parallel right that diaphragm neighboring top surface is equipped with two circles
The outer bulge loop and internal projecting ring set constitute diaphragm film trap between outer bulge loop and internal projecting ring, the outer peripheral edge of flutter board extends downwardly
There is a sidewall portion in embedded diaphragm film trap, the bottom margin that pump head lid corresponds to internal projecting ring is extended with and compresses flutter board top edge
Crimping bulge loop, crimping bulge loop and pump head lid side wall, which are constituted, is suitable for the compression seal groove that outer bulge loop extending end compresses sealing.
The pump case sealing structure, when pump head lid and the fixed installation of pump head seat, flutter board is pressed on diaphragm by pump head lid
It is upper, since diaphragm is semi-rigid elastic material, the sidewall portion of flutter board is squeezed between outer bulge loop and internal projecting ring simultaneously
The bottom of diaphragm film trap is compressed, which constitutes the first seal structures, in addition, when pump head lid and pump head seat are fixedly mounted,
Outer bulge loop grafting enters to compress seal groove, and since outer bulge loop is similarly semi-rigid elastic material, outer bulge loop extending end elasticity compresses
In the top surface for compressing seal groove, which constitutes the second seal structures, and double sealing structure is under stabilized pressure pump longtime running, energy
It enough realizes long term seal, can achieve the effect that long-term seal, to improve the sealing reliability of stabilized pressure pump, reduce voltage stabilizing
The probability leaked is pumped, and then extends the service life of stabilized pressure pump.
The pump head lid inner wall is equipped with inclined side, and inclined side constitutes compression seal groove, inclined side with bulge loop is crimped
When being fixedly mounted convenient for pump head lid and pump head seat, outer bulge loop can be close to inclined side and slide into compression seal groove, avoid out
The problem of existing gap leads to leakage.
Diaphragm top surface central position has given off a plurality of reinforcing rib, the end of a plurality of reinforcing rib and convex outward
Mutually in succession, reinforcing rib avoids internal projecting ring for a long time using deforming to ring, and internal projecting ring is caused gap occur with sidewall portion.
The diaphragm is semi-rigid elastic material, and semi-rigid elastic material has more preferably sealing performance.
The utility model has the beneficial effects that：
A kind of pump head improving water leak preventing structure of the utility model, which constitute the second seal structures, dual-seal
Structure can realize long term seal under stabilized pressure pump longtime running, can achieve the effect that long-term seal, to improve voltage stabilizing
The sealing reliability of pump reduces the probability that stabilized pressure pump leaks, and then extends the service life of stabilized pressure pump.

Fig. 2 is the diaphragm structural schematic diagram of the utility model.
Fig. 3 is the plate structure schematic diagram of fetching water of the utility model.
Fig. 4 is the pump head lid structural schematic diagram of the utility model.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figures 1 to 4, a kind of pump head improving water leak preventing structure, including pump head lid 1 and bottom cover 2, pump head lid 1
Cooperation is equipped with flutter board 3, diaphragm 4, pump head seat 5 and balance wheel seat 6,4 outer periphery of the diaphragm successively between bottom cover 2
Edge top surface is equipped with two circles parallel opposed outer bulge loop 7 and internal projecting ring 8, and diaphragm is constituted between outer bulge loop 7 and internal projecting ring 8
Film trap 9, the outer peripheral edge of flutter board 3 extend downwardly the sidewall portion 10 in embedded diaphragm film trap 9, and pump head lid 1 corresponds to internal projecting ring 8
Bottom margin be extended with the crimping bulge loop 11 for compressing 3 top edge of flutter board, crimping bulge loop 11 constitutes suitable with 1 side wall of pump head lid
The compression seal groove 12 of sealing is compressed in 7 extending end of outer bulge loop.
The pump case sealing structure, when pump head lid 1 and pump head seat 5 are fixedly mounted, pump head lid 1 by flutter board 3 be pressed on every
Diaphragm 4 it is upper, since diaphragm 4 is semi-rigid elastic material, the sidewall portion 10 of flutter board 3 is squeezed into outer bulge loop 7 and interior
Between bulge loop 8 and the bottom of diaphragm film trap 9 is compressed, which constitutes the first seal structures, in addition, in pump head lid 1 and pump head
When seat 5 is fixedly mounted, 7 grafting of outer bulge loop enters to compress seal groove 12, since outer bulge loop 7 is similarly semi-rigid elastic material, evagination
7 extending end elasticity of ring is pressed against the top surface for compressing seal groove 12, and which constitutes the second seal structures, double sealing structure
Under stabilized pressure pump longtime running, long term seal can be realized, can achieve the effect that long-term seal, to improve stabilized pressure pump
Sealing reliability reduces the probability that stabilized pressure pump leaks, and then extends the service life of stabilized pressure pump.
1 inner wall of pump head lid is equipped with inclined side 13, and inclined side 13 constitutes compression seal groove 12 with bulge loop 11 is crimped,
When inclined side 13 is fixedly mounted convenient for pump head lid 1 with pump head seat 5, outer bulge loop 7 can be close to inclined side 13 and slide into compression
In seal groove 12, the problem of gap leads to leakage is avoided the occurrence of.
4 top surface central position of the diaphragm has given off a plurality of reinforcing rib 14, the end of a plurality of reinforcing rib 14 outward
In succession with 8 phase of internal projecting ring, reinforcing rib 14 avoids energy internal projecting ring for a long time using deforming, and causes internal projecting ring 8 and sidewall portion
10 there is gap.
The diaphragm 4 is semi-rigid elastic material, and semi-rigid elastic material has more preferably sealing performance.
