Main part 100 is specifically described:
As shown in Fig. 2, main part 100 includes: fixing axle 110, coil 120, iron core 130, piston 140.Coil 120 is wound
In outside fixing axle 110, for iron core 130 by 150 reciprocating movement of elastic component in fixing axle 110, piston 140 is fixed on iron core 130
On, piston 140 is abutted or is separated with the notch of pump slot 233.In the present embodiment, elastic component 150 is spring.In other embodiments
In, elastic component 150 is elastic rubber.
In the present embodiment, water inlet tap 210 and faucet 220 have back-off, and fixing axle 110 has catching groove, shunting disk 230
It is fastened by back-off and catching groove and water inlet tap 210 and faucet 220.
The working principle for the electromagnetic pump 20 for improving discharge stability is illustrated:
Coil 120, which is powered, generates south, the arctic；
Iron core 130 is moved back and forth in fixing axle 110 under the action of electromagnetic force by elastic component 150；
Iron core 130 is abutted or is separated with the notch of pump slot 233 with piston 140 in turn；
The reciprocating motion of piston 140 generates positive and negative pressure in fixing axle 110, when water inlet tap 210 is intake, non-return of intaking
Plug 240 is opened, and water outlet backflow preventing mouth plug 250 is closed, and when faucet 220 is discharged, water inlet backflow preventing mouth plug 240 is closed, and is discharged backflow preventing mouth plug 250
It opens；
Water flow is entered by water inlet tap 210, is entered by the first intake tunnel 211 and the second intake tunnel 231 of perforation
In cavity 300, then passes through pump slot 233 and flowed by the first exhalant canal 221 penetrated through and the second exhalant canal 232 from faucet 220
Out.
The above-mentioned analysis to Inlet and outlet water structural portion 200 is it is found that be split type due to being discharged backflow preventing mouth plug 250 and faucet 220
The pressed end 251 of structure, water outlet backflow preventing mouth plug 250 is the extruding force by shunting disk 230 and is fixed on faucet 220, water flow
It realizes and pumps under the action of main part 100, and flowed out incessantly by water outlet backflow preventing mouth plug 250 and by faucet 220, water flow
Meeting generate certain impact force to water outlet backflow preventing mouth plug 250, and if things go on like this, water outlet backflow preventing mouth plug 250 can occur to loosen unavoidably, deviate now
As, and then affect the stability of flow.
To prevent water outlet backflow preventing mouth plug 250 from loosening, shift phenomenon occurs under long-term water flow impact pressure effect, to improve water
The stability of stream is provided with flexible positioning rubber plug especially in the first exhalant canal 221 and the second exhalant canal 232
400.Crushing block 410 squeezes the pressed end 251 of water outlet backflow preventing mouth plug 250 under the action of shunting disk 230, due to squeezing
A degree of elastic deformation can occur for crushing block 410 under the action of power, to further enhance squeezing to pressed end 251
Pressure, allowing water outlet, backflow preventing mouth plug 250 is more stable is fixed on faucet 220, while also improving the air-tightness of connection.
Locating piece 420 is arranged in check cavity 252, and the edge of locating piece 420 and the cavity wall of check cavity 252 are formed and be interference fitted, locating piece
420 pairs of water outlet backflow preventing mouth plugs 250 play the role of positioning, prevent water outlet backflow preventing mouth plug 250 from shifting under the influence of the impact force
Phenomenon, even if small offset has occurred in water outlet backflow preventing mouth plug 250, the elastic force of locating piece 420 can also be carried out shift phenomenon
It corrects.In addition, the assembly of water outlet backflow preventing mouth plug 250 is also helped by setting positioning rubber plug 400, for example, first by crushing block 410
It is embedded on shunting disk 230, is then again pressed on water outlet backflow preventing mouth plug 250 on locating piece 420 by check cavity 252, will finally divide
Flow table 230, positioning rubber plug 400 and water outlet backflow preventing mouth plug 250 are formed by entirety and are assemblied on faucet 220, in this way can be very big
The efficiency for promoting assembly, improves the stability of assembly.
It should also be noted that and moved back and forth with piston 140 along the central axis of fixing axle 110 due to iron core 130, shunted
The center of disk 230 offers pump slot 233 corresponding with piston 140, can just be conducive to iron core 130 in this way with piston 140
The balance and stability realized and pumped are moved back and forth along the central axis of fixing axle 110.Therefore, to better conform to above structure,
Structure improvement is carried out to the second exhalant canal 232, that is, the central axis of the first exhalant canal 221 and the second exhalant canal 232
Central axis forms angle, and the second exhalant canal 232 is penetrated through by the cell wall of pump slot 233 to the first exhalant canal 221, so that second
The channel design of the formation tilting of exhalant canal 232.When piston 140 pushes to water flow to pump slot 233, the second water outlet of tilting
Channel 232 is conducive to guide the water flow pumped at slot 233 into first exhalant canal 221, improves the stability and smoothness of water outlet.
Further, water outlet backflow preventing mouth plug 250 has notch 253, notch 253 and pressed end far from one end of pressed end 251
It is connected between 251 by training wall 254.Pressed end 251 is connected at the access port of the first exhalant canal 221, and 253, notch
In in the first exhalant canal 221, training wall 254 extends to another tunnel ends by an access port of the first exhalant canal 221
Mouthful, training wall 254 is tightly attached to the conduit wall of the first exhalant canal 221.Since water outlet backflow preventing mouth plug 250 is soft colloform texture,
When crushing block 410 squeezes the pressed end 251 of water outlet backflow preventing mouth plug 250 under the action of shunting disk 230, pressed end 251 is not
Exempt from that a degree of deformation can occur, the deformation meeting of pressed end 251 is so that the training wall 254 contacted also occurs to a certain degree
Deformation, the deformation of training wall 254 can make notch 253 that a degree of deformation occur again, and the notch 253 of deformation can make to obtain
The function of water backflow preventing mouth plug 250 is lost.By compared with the traditional water outlet backflow preventing mouth plug 15 of Fig. 1 it is found that water outlet backflow preventing mouth plug of the invention
250 want longer in the length of training wall 254, so, even if the deformation of pressed end 251 has influenced training wall 254, by
Longer in the length of training wall 254, longer training wall 254 can gradually eliminate the deformation of generation, so that deformation cannot reach
At notch 253, to not impact to notch 253, and then the stability of water flow is improved.
A kind of electromagnetic pump 20 of raising discharge stability of the invention connects by setting main part 100 and with main part 100
The Inlet and outlet water structural portion 200 connect, the setting positioning rubber plug 400 especially in the first exhalant canal 221 and the second exhalant canal 232,
It prevents water outlet backflow preventing mouth plug from loosening, shift phenomenon occurs under the action of for a long time by water flow impact pressure, improves water flow
Stability.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
