Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

Example one

As shown in fig. 1-2, the utility model discloses a tea tray drainage device, including the drainage main part 1 that link up from top to bottom, the upper end and the lower extreme of drainage main part 1 are provided with the joint 2 of being connected with drain pipe 8, connect 2 middle parts to be provided with the well cavity 3 that link up with drainage main part 1, the inside diaphragm 4 that is provided with of drainage main part 1, diaphragm 4 is separated into upper and lower two cavitys with drainage main part 1 is inside, and diaphragm 4 middle part is provided with through-flow hole 7 and makes upper and lower two cavitys communicate. The drain body 1 and the membrane 4 are made of an elastic material. The elastic material is foamed EVA or nitrile rubber or silicon rubber, and the drainage main body 1 is football-shaped or cylindrical.

In the embodiment, the joint 2, the drainage body 1 and the diaphragm 4 are integrally formed, and the forced demolding process is adopted in the production process.

As shown in fig. 2, the diaphragm 4 gradually increases in thickness from the central axis of the through-flow hole 7 along the outer end. The diaphragm 4 is provided with a structure with a thin middle part and a thick outer end, so that the diaphragm 4 extrudes towards the middle part to close the through-flow hole 7 when being held and pressed. If the thickness of the diaphragm 4 is set to be uniform, the folding and the distortion are easily produced at the time of gripping, and the effect of closing the through-flow hole cannot be achieved.

Dimension H for setting through-flow hole 7₁Larger than the dimension H of the hollow bore of the joint₂So that the sucked tea leaves do not gather at the diaphragm and can pass through the through-flow hole 7 and flow into the drain barrel.

As shown in figures 3 and 4, when in use, the tea tray drainage device is arranged in the middle of the drainage pipe 8, one end of the drainage pipe 8 is connected with the drainage port 9 of the tea tray, and the other end of the drainage pipe extends into the bottom end of the tea water barrel 10. Under the normal condition without blockage of the water outlet 9, the tea liquid directly flows into the tea tray drainage device through the drainage pipe 8 and then sequentially flows into the tea water barrel 10 through the hollow hole 3 of the upper end connector, the through hole 7 and the hollow hole 3 of the lower end connector. The tea liquid in the tea tray is discharged completely through the siphon force formed by natural flow.

The utility model discloses tea tray drainage device has three kinds and holds the method of pressing, holds through three kinds and presses the method, reaches different supplementary effects. The details are as follows:

1. repeatedly holding and pressing and releasing drainage main body at upper cavity

As shown in fig. 5, three processes are involved:

firstly, the upper cavity deforms after the upper cavity 5 is held and pressed, at the moment, the through-flow hole 7 is basically in a closed state under the action of holding pressure, the upper cavity 5 exhausts air upwards, and tea leaves at a water outlet of the tea tray are pushed out.

Secondly, after the upper cavity 5 is released, the upper cavity 5 is quickly and elastically restored, partial vacuum is formed at the moment, the upper cavity 5 sucks tea liquid and part of tea dust, and the through hole 7 is gradually opened in the elastic restoration process.

And thirdly, when the upper cavity 5 is completely restored to the original state, the through hole 7 is completely opened, and the tea liquid and the tea dust enter the lower cavity 6 through the through hole 7 and are discharged from the hollow hole 3 of the lower end connector 2.

And repeating the three processes, and continuously draining water to form siphon suction force so as to drain the tea liquid in the tea tray.

2. Repeatedly holding and pressing and releasing the drainage body at the lower cavity

When no tea liquid exists in the tea liquid barrel, the lower cavity 6 only sucks air when the lower cavity 6 is held and pressed, and formed siphon assisting force is small. When there is more tea liquid in the tea liquid, as shown in fig. 6, the drain pipe 8 is immersed in the tea liquid, and three processes of this state are as follows:

after the lower cavity 6 is pressed, the lower cavity 6 is deformed, at the moment, the through-flow hole 7 is basically in a closed state under the action of the holding pressure, and the lower cavity 6 exhausts air downwards.

Secondly, after the lower cavity 6 is released, the lower cavity 6 is quickly and elastically restored, partial vacuum is formed at the moment, the lower cavity 6 sucks tea liquid, and the through hole 7 is gradually opened in the elastic restoration process.

And thirdly, when the lower cavity 6 is completely restored to the original state, the through-flow hole 7 is completely opened, and the lower cavity 6 provides secondary siphon assistance, so that the upper cavity 5 forms vacuum force to suck tea liquid, and the tea liquid flows out from the drain pipe 8 through the through-flow hole 7.

And repeating the three processes, and continuously draining water to form siphon suction force so as to drain the tea liquid in the tea tray.

3. Repeated holding and releasing of the drainage body in the position of the membrane

As shown in fig. 7, three processes are involved:

firstly, the position of the middle diaphragm 4 is held and pressed, the through-flow hole 7 is closed, at the moment, the upper cavity 5 and the lower cavity 6 work independently, the upper cavity 5 exhausts air upwards, tea leaves at the water outlet of the tea tray are pushed out, and the lower cavity 6 exhausts air downwards.

Secondly, the drainage main body 1 is released, the upper cavity 5 and the lower cavity 6 elastically recover, the upper cavity 5 sucks upper air, and the lower cavity 6 sucks lower air and tea liquid in the drainage barrel 10. The throughflow orifice 7 opens gradually during the elastic return.

And thirdly, when the upper cavity 5 and the lower cavity 6 are completely restored to the original state, the through-flow hole 7 is completely opened, and the lower cavity 6 provides secondary siphon assistance, so that the upper cavity 5 forms vacuum force to suck tea liquid, and the tea liquid flows out from the drain pipe 8 through the through-flow hole 7.

And repeating the three processes, and continuously draining water to form siphon suction force so as to drain the tea liquid in the tea tray. The utility model discloses a setting of upper and lower cavity for go up cavity 5 and separate with lower cavity 6 when upwards exhausting air, through the time difference that elasticity resumes, go up cavity 5 and delayed switching on with lower cavity 6, thereby make cavity 5 can effectually inhale the tea liquid of tea tray when elasticity resumes.

When the tea leaves are gathered in the tea tray water outlet 9, the process of pushing the tea leaves in the water outlet 9 for draining liquid can be realized by repeatedly holding and pressing and releasing the upper cavity body 5 of the drainage main body 1 or the diaphragm part of the drainage main body 1. The diaphragm position of repeatedly holding pressure and releasing drainage main part 1 both can realize pushing away the tea grounds, and the local vacuum that cavity 6 provided down simultaneously inhales again, can provide stronger suction, and required holding pressure number of times is few, can produce effectual vacuum and carry out quick drainage, and drainage effect is good.
