Abstract
The utility model discloses a detergent storage device with a one-way valve, wherein the detergent storage device comprises a storage device, a sealing cover, a fluid delivery unit and a pipeline, wherein the storage device is used for storing a detergent; the sealing cover is used for sealing the storage device; the fluid delivery unit is communicated with the storage device; the pipeline is connected with the fluid delivery unit; the storage device or the sealing cover is provided with a first one-way valve which is communicated with the inside and outside of the storage device; the conduction direction of the first one-way valve is from the outside of the storage device to the inside of the storage device; the first one-way valve can be used for balancing the pressures inside and outside of the storage device, thus the liquid detergent can be delivered smoothly; and the pipeline is connected with a second one-way valve, the conduction direction of the second one-way valve is from the inside of the pipeline to the outside of the pipeline, and the second one-way valve can prevent impurities outside the pipeline from backflow to cause detergent pollution.
Description
Technical field
The utility model relates to a kind of washing agent storage device, especially a kind of washing agent storage device that improves structure.
Background technology
The liquid type washing agent storage device of prior art has comprised memory, liquid supply unit and the inlet pipeline of liquid type washing agent.Said inlet pipeline connects the washtub of washing machine.
Wherein, the memory of prior art is to comprise an input port and outlet, input port fitting tight lid.Said liquid supply unit can controlling liquid class washing agent input, the outlet of an end connected storage, the other end directly connect washtub.
But by the memory that seal cover seals fully, outside air can't get into memory, and when liquid level in the liquid use descended, the upper strata air space was easy to form negative pressure, and liquid can not be thrown in smoothly.And the material in the washtub gets into liquid type washing agent storage device from the liquid supply unit easily, makes it diluted or contaminated.
So, need a kind of new technical scheme to address the above problem.
The utility model content
The purpose of the utility model is the deficiency that exists to prior art, provides a kind of and prevents that washing agent is contaminated in the washing agent storage device, and the washing agent storage device with check valve that washing agent is thrown in smoothly.
For realizing above-mentioned purpose, the washing agent storage device that the utlity model has check valve can adopt following technical scheme:
A kind of washing agent storage device with check valve, comprise memory, be sealed in seal cover on the memory in order to the storage washing agent, with the liquid supply unit of memory connection and the pipeline that is connected with the liquid supply unit; Said memory is provided with and is communicated with the first inside and outside check valve of memory, and the conducting direction of this first check valve is a direction in the export-oriented memory of memory; Said pipeline is connected with second check valve, and the conducting direction of this second check valve be in pipeline outside pipeline direction.
Compare with background technology, the washing agent storage device that the utlity model has check valve is provided with and is communicated with the first inside and outside check valve of memory, and the conducting direction of this first check valve is a direction in the export-oriented memory of memory.The effect of this first check valve is that when pressure reduced in memory, inside and outside differential pressure made first one-way valve opens, ambient atmos entering memory, the negative pressure that balance descends and produced owing to liquid level, the continuous delivery of realization liquid type washing agent; And when stopping to deliver the liquid type washing agent; Memory inside pressure no longer changes, when inside and outside pressure equates, and first closed check valve; Outside air stops to get into memory, stops owing to liquid type washing agent contact outside air causes volatilization to be gone bad in the memory, evaporation becomes dry and the smell diffusion.Said pipeline is connected with second check valve, and the conducting direction of this second check valve be in pipeline outside pipeline direction.The effect of this second check valve is that during the action of liquid supply unit, this second check valve is opened under the effect of ducted gas or fluid pressure, the discharge of liquid type washing agent; And when the liquid supply unit stops, second closed check valve, the outer material adverse current of pipeline is gone in the pipeline, is polluted by external substance to avoid the washing agent in the liquid type washing agent storage device.
For realizing above-mentioned purpose, the washing agent storage device that the utlity model has check valve also can adopt following technical scheme:
A kind of washing agent storage device with check valve, comprise memory, be sealed in seal cover on the memory in order to the storage washing agent, with the liquid supply unit of memory connection and the pipeline that is connected with the liquid supply unit; Said seal cover is provided with and is communicated with the first inside and outside check valve of memory, and the conducting direction of this first check valve is a direction in the export-oriented memory of memory; Said pipeline is connected with second check valve, and the conducting direction of this second check valve be in pipeline outside pipeline direction.
Compare with background technology, the washing agent storage device that the utlity model has check valve is provided with and is positioned on the seal cover and is communicated with the first inside and outside check valve of memory, and the conducting direction of this first check valve is a direction in the export-oriented memory of memory.The effect of this first check valve is that when pressure reduced in memory, inside and outside differential pressure made first one-way valve opens, ambient atmos entering memory, the negative pressure that balance descends and produced owing to liquid level, the continuous delivery of realization liquid type washing agent; And when stopping to deliver the liquid type washing agent; Memory inside pressure no longer changes, when inside and outside pressure equates, and first closed check valve; Outside air stops to get into memory, stops owing to liquid type washing agent contact outside air causes volatilization to be gone bad in the memory, evaporation becomes dry and the smell diffusion.Said pipeline is connected with second check valve, and the conducting direction of this second check valve be in pipeline outside pipeline direction.The effect of this second check valve is that during the action of liquid supply unit, this second check valve is opened under the effect of ducted gas or fluid pressure, the discharge of liquid type washing agent; And when the liquid supply unit stops, second closed check valve, the outer material of pipeline can not flow ipe in, polluted by external substance to avoid the washing agent in the liquid type washing agent storage device.
