Background technique
Generally speaking, Miniature liquid pump is all widely used on the products such as coffee machine, water purifier, household electric appliance, in order to carry fluid or gas, and carries out topping up work, replaces with manual labor by this, and saves time and muscle power.The working principle of existing liquid pump: the circular movement of motor, the barrier film of pump inside is made to do reciprocatory motion by mechanical device, thus the air in the pump chamber of fixed volume is compressed, draw stretch formed vacuum (malleation/negative pressure), pressure difference is produced at pump pump mouth place and external atmosphere pressure, under the effect of pressure difference, by valve, liquid pressure (suction) is entered pump chamber, then discharge from water outlet.Claimant in actual use, find that existing Miniature liquid pump is for discharge liquid uninterrupted, certain proportional relation is there is with product design volume, the fluid flow that Miniature liquid pump (same volume is compared) is discharged is less, and the noise ratio that large discharge liquid pump produces is larger, for the small household appliances industry articles for use that current noise requirements is higher, low noise product just can not disturb life at home, therefore need to provide a and can provide large discharge, the Miniature liquid pump of noise can be reduced again.
Model utility content
The utility model provides a kind of Miniature liquid pump, reduces noise, effectively reduces leak of liquid, improves flow, reduces the load of machine itself, finally increases the service life.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Miniature liquid pump, this Miniature liquid pump comprises the upper cover, valve plate, umbrella fourth, leather cup, cylinder body, rocker, eccentric wheel, bottom and the motor that pass through long screw and be fixedly connected with, it is characterized in that: described eccentric wheel and motor shaft are assembled, bottom and motor upper end are threaded connection, eccentric wheel top is provided with steel bead groove, steel ball in draw point bottom and steel bead groove is slidably connected, and draw point top is inserted and is connected in the middle part of rocker; Described rocker and leather cup are assembled in cylinder body, and the groove on the pendulum tooth of rocker and leather cup abuts against, and the bottom of described umbrella fourth is embedded in leather cup, and the top of umbrella fourth and valve plate are assembled; Also be provided with valve block in described valve plate inside, be provided with sealing gasket between valve plate and upper cover, described valve block, formation import and export sealing and pipe passage between valve plate and upper cover, described upper tops is provided with liquid entering hole and liquid outlet.
Described valve block is provided with multiple liquid outlet opening, and liquid outlet opening is sector structure, and upper cover liquid entering hole and liquid outlet adopt large aperture design.
Compared with prior art, the utility model at least has the following advantages:
By above-mentioned the technical solution of the utility model, in reduction noise, first on eccentric wheel, a steel ball is increased, reduced the metal friction of draw point by steel ball, secondly valve block designs for absolute construction, has multiple liquid outlet opening, liquid outlet opening is sector structure, liquid, for the impact of valve block fan-shaped outlet and closed, can play the requirement reducing noise, and the backflow of inside design also contributes to reducing feed liquor flow noise; In increase flow, valve block adopts Seal Design that the sealing of Miniature liquid pump is improved, effective minimizing leak of liquid, thus improve flow, upper cover liquid entering hole and liquid outlet are for strengthening design simultaneously, and make turnover liquid increased flow capacity, interior leather cup is designed to multiple liquid storage capacity, during machine run, the liquid entered and the fluid flow of discharge larger; In addition, upper cover liquid entering hole and liquid outlet adopt large aperture design, reduce the load of machine itself, extension device working life.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of a kind of Miniature liquid pump that the utility model embodiment provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technological scheme in the utility model, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, for a kind of Miniature liquid pump that the utility model embodiment proposes, this Miniature liquid pump comprises the upper cover 1, valve plate 2, umbrella fourth 3, leather cup 4, cylinder body 5, rocker 6, eccentric wheel 7, bottom 8 and the motor 9 that pass through long screw and be fixedly connected with, it is characterized in that: eccentric wheel 7 and motor shaft are assembled, bottom 8 and motor 9 upper end are threaded connection, eccentric wheel 7 top is provided with steel bead groove, steel ball 11 in draw point 10 bottom and steel bead groove is slidably connected, and draw point 10 top is inserted and is connected in the middle part of rocker 6; Rocker 6 and leather cup 4 are assembled in cylinder body 5, and the groove on the pendulum tooth of rocker 6 and leather cup 4 abuts against, and the bottom of umbrella fourth 3 is embedded in leather cup 4, and top and the valve plate 2 of umbrella fourth 3 are assembled; Also be provided with valve block 12 in valve plate 2 inside, be provided with sealing gasket 13 between valve plate 2 and upper cover 1, valve block 12, formed to import and export seal and pipe passage between valve plate 2 and upper cover 1, upper cover 1 top is provided with liquid entering hole 14 and liquid outlet 15.
