In the second state, the liquid collecting unit extends out, and one end of the ejector pin 3 is located in the liquid collecting unit, so that the liquid collecting unit can receive the additive outside the ejector pin 3.
In detail, a check valve (not shown in the figure) is arranged at the liquid outlet of the additive liquid storage box, and the check valve comprises a valve body and a spring for enabling the valve body to contract. When the additive liquid storage box is placed into the cavity 1, the thimble 3 pushes the valve body of the one-way valve open, so that the liquid outlet of the additive liquid storage box is opened and can be communicated with the flow guide channel 4 of the flow guide pipe 2. Meanwhile, the liquid outlet of the additive liquid storage box drives the liquid collection unit to shrink, so that one end of the ejector pin 3 can be exposed out of the liquid collection unit and is used for jacking up the liquid outlet of the additive liquid storage box, and the flow guide channel 4 is communicated with the additive liquid storage box. When the additive liquid storage box is drawn out from the cavity 1, the spring of the one-way valve pushes the valve body out, so that the liquid outlet of the additive liquid storage box is closed. Meanwhile, the liquid collection unit extends out, the ejector pin 3 is covered in the liquid collection unit and is filled with the additive outside the ejector pin 3.
In a preferable scheme, the liquid collecting unit covers the end part of the thimble 3 used for jacking one end of the liquid outlet of the additive liquid storage box when extending out. In the above-mentioned scheme, can be used for ejecting the one end cover of additive stock solution box liquid outlet with thimble 3 when liquid collecting unit stretches out, make the additive of the outside adhesion of thimble 3 can all drip to liquid collecting unit in, further promote leak protection liquid effect.
In a preferred scheme, the cross section of the thimble 3 is provided with a center and a plurality of flow guide parts which are radially arranged outwards along the center; the space between the flow guide part and the inner wall of the flow guide pipe 2 forms the flow guide channel 4.
In a further scheme, the cross section of the thimble 3 is in a cross shape.
Above-mentioned scheme can increase the intensity of thimble 3, promotes 3 backs down the stability of check valve of thimble when additive stock solution box is put into cavity 1.
In a further scheme, one end of the thimble 3, which is used for jacking the one-way valve of the additive liquid storage box, is set to be of a conical structure, so that the thimble 3 can conveniently extend into a liquid outlet of the additive liquid storage box. And a notch is formed in the outward side of the valve body of the one-way valve and used for enabling the thimble 3 to extend into the notch.
In a further aspect, as shown in fig. 3 and 4, the liquid collection unit comprises a sleeve 5 and an elastic member 6.
The sleeve 5 is sleeved outside the flow guide pipe 2 and the ejector pin 3, and a space allowance is formed between the ejector pin 3 and the inner wall of the sleeve 5 to form a liquid collection cavity 7 of the liquid collection unit for containing additives outside the ejector pin 3. The elastic element 6 is sleeved outside the draft tube 2 and arranged between the sleeve 5 and the chamber 1, so that the sleeve 5 keeps extending trend.
In the above-mentioned scheme, utilize elastic component 6 to make sleeve pipe 5 keep stretching out the trend, can realize that sleeve pipe 5's automation stretches out, and when additive stock solution box took out from cavity 1, elastic component 6 can make sleeve pipe 5 have fine followability to thimble 3, and the terminal surface of the liquid outlet of additive stock solution box is hugged closely to the terminal surface of sleeve pipe 5, makes the outside additive of thimble 3 can all drip to in the sleeve pipe 5.
In a further scheme, when the liquid collecting unit is in a contracted state, the distance between one end of the sleeve 5 far away from the elastic piece 6 and one end of the ejector pin 3 is smaller than the distance between one end of the draft tube 2 far away from the elastic piece 6 and one end of the ejector pin 3.
Specifically, a space allowance is formed between the thimble 3 and the inner wall of the sleeve 5 to form a liquid collecting cavity 7, and the liquid collecting cavity 7 and the flow guide channel 4 are matched to form an additive channel from the additive liquid storage box to the water feeding and discharging channel 14.
In detail, as mentioned above, the length of the thimble 3 is greater than the length of the draft tube 2, and therefore, a part of the thimble 3 is disposed in the draft tube 2 and a part thereof is exposed to the draft tube 2.
