Pipe plunger displacement pump is connected；Described second ratchet mechanism includes the second ratchet and the second ratchet matched, the second ratchet
Suitable with driving gear, the second ratchet is connected by the second crank and the second slide block, and the second slide block is with corresponding
Corrugated tube plunger displacement pump is connected.Wherein, the internal structure of corrugated tube plunger displacement pump such as spring structure, enough resiliences, stretch
Contracting freely, uses corrugated tube plunger displacement pump can reduce friction, increases sealing, additionally can also reduce structural member,
Simplify the structure.
Further, described motor is driven by the first the most reverse ratchet mechanism and the second ratchet mechanism respectively
Two corrugated tube plunger displacement pumps: when motor rotates forward, the first ratchet mechanism runs and drives corresponding ripple tubing string
Plug pump work, the second ratchet mechanism is in the corrugated tube plunger air pump inoperative of idling conditions and its correspondence；Work as electricity

Further, described frame structure includes upper cover and lower cover, and motor is arranged on the outside of upper cover.
Work, the first described ratchet and the second ratchet during in order to ensure two bellows structure plunger displacement pump differences
Profile of tooth is in opposite direction, the first ratchet and the second ratchet towards on the contrary；First ratchet mechanism and the second ratchet mechanism
It is symmetrically arranged at the both sides of driving gear.
Beneficial effect: this utility model uses the plunger displacement pump of two-chamber bellows structure, by by two groups of pumps integrated
Body, is used in washing machine, and the structure making product is smaller and more exquisite, cost is cheaper, install and more may be used
Lean on, it is possible to extracting two kinds of different liquid detergents, function is more comprehensively.
It is mounted with that washing machine of the present utility model has only to utilize a motor just can extract two or more liquid
Body, greatly reduces cost.

Detailed description of the invention
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model not office
It is limited to described embodiment.
As shown in Figure 1 to Figure 3, the two-chamber bellows structure plunger displacement pump of a kind of washing machine of the present utility model, bag
Include frame structure (including upper cover 14 and lower cover 2), and 13, two types of the motor being installed in frame structure
Chamber 7, driving gear the 12, first ratchet mechanism and the second ratchet mechanism, motor 13 drives driving gear 12,
Driving gear 12 drives the first ratchet mechanism and the second ratchet mechanism, two die cavities 7 to be respectively arranged in frame respectively
Top within shelf structure, and die cavity 7 are equipped with corrugated tube plunger displacement pump 15, two corrugated tube plunger displacement pumps 15
Top double with two of frame structure top respectively import and export 1 and be connected, the end of two corrugated tube plunger displacement pumps 15
End is connected with the first ratchet mechanism and the second ratchet mechanism by the first slide block 8 and the second slide block 3 respectively；First
Ratchet mechanism includes the first ratchet 10 and the first ratchet 11 matched, the first ratchet 11 and driving gear 12
Suitable, the first ratchet 10 is connected with the first slide block 8 by the first crank 9, and the first slide block 8 is with corresponding
Corrugated tube plunger displacement pump 15 is connected；Second ratchet mechanism includes the second ratchet 5 and the second ratchet 6 matched,
Second ratchet 6 is suitable with driving gear 12, and the second ratchet 5 is by the second crank 4 and the second slide block 3 phase
Even, the second slide block 3 is connected with corresponding corrugated tube plunger displacement pump 15.In order to ensure two bellows structure plungers
Working during pump difference, the profile of tooth of the first ratchet 11 and the second ratchet 6 is in opposite direction, the first ratchet 10 and second
Ratchet 5 towards on the contrary；First ratchet mechanism and the second ratchet mechanism are symmetrically arranged at driving gear 12
Both sides.
Specific works principle of the present utility model is:
Motor 13 drives two corrugated tubes by the first the most reverse ratchet mechanism and the second ratchet mechanism respectively
