[0037] First embodiment, refer to Figures 1-2 .

[0038] The present embodiment provides a tea tray drainage accessory for realizing drainage of a tea tray device. The tea tray drainage accessory comprises a hollow elastic ball 1 and a first drainage channel 3 and a second drainage channel 4, one end of the first drainage channel 3 is communicated with a water inlet end of the hollow elastic ball 1, and one end of the second drainage channel 4 is communicated with a water outlet end of the hollow elastic ball 1. The tea tray device comprises a tea tray provided with a drainage port and a tea tray drainage device, and the tea tray drainage device comprises a sewage bucket or a sewer. One end of the first drainage channel 3 is communicated with the water inlet end of the hollow elastic ball 1, and the other end is communicated with the drainage port of the tea tray; one end of the second drainage channel 4 is communicated with the water outlet end of the hollow elastic ball 1, and the other end is communicated with the sewage bucket or the sewer. The first drainage pipe 31 and the second drainage pipe 41 are drainage hoses, the hollow elastic ball 1 can be integrally provided with the drainage hose, or one end of the first drainage pipe 31 is communicated with the water inlet end of the hollow elastic ball 1 through a first pipe joint 32, and one end of the second drainage pipe 41 is communicated with the water outlet end of the hollow elastic ball 1 through a second pipe joint 42.

[0039] The tea tray drainage accessory is provided with a valve assembly air vent 2 at the first pipe joint 32 of the first drainage channel 3 (as shown in Figure 1 ). The valve assembly air vent 2 is normally open, and in the natural state, the air vent 2 is in the open state.

[0040] In this embodiment, the valve assembly air vent 2 is normally open, and when the tea tray is normally draining, the valve assembly air vent 2 is used to achieve the intercommunication between the hollow elastic sphere 1 and the atmosphere, so that the drainage is more smooth.

[0041] The valve assembly air vent 2 is set to be closed when the hollow elastic sphere 1 is squeezed, and the valve assembly air vent 2 is closed and does not vent; when the hollow elastic sphere 1 is full of water to the valve assembly air vent 2, the valve assembly air vent 2 is closed and does not leak water. When the hollow elastic sphere 1 is squeezed, the water and gas in the sphere will not overflow through the air vent 2.

[0042] Specifically, the structure of the valve assembly air vent 2 is set as follows: the air vent 2 includes an air path channel 21, the valve assembly includes a lightweight sphere 22 and a supporting member 23, the supporting member 23 allows air or water to pass through, and the supporting member 23 is placed in the air path channel 21 and supports the lightweight sphere 22. The lightweight sphere 22 can float on water, and when the water in the hollow elastic sphere 1 fills the air path channel 21, the water can lift the lightweight sphere 22 to close the air vent 2, achieving the effect of preventing water overflow.

[0043] When normally draining, the lightweight sphere 22 falls on the supporting member 23 (as shown in Figure 1 ), the air vent 2 is opened, the inside of the hollow elastic sphere 1 is communicated with the atmosphere, and the drainage is more smooth. When the first drainage channel 3 or the second drainage channel 4 is blocked by tea residue or foreign matter during the drainage process, in order to achieve better unblocking effect, the second drainage channel 4 or the first drainage channel 3 at the other end of the hollow elastic sphere 1 which is not blocked can be artificially blocked (the drainage hose at the other end of the hollow elastic sphere 1 which is not blocked can be pinched or folded to close), and then the hollow elastic sphere 1 is squeezed to generate a large positive pressure in the hollow elastic sphere 1 to impact the tea residue and foreign matter, and the unblocking is performed. As the hollow elastic sphere 1 is squeezed, the lightweight sphere 22 closes the air vent 2 under the action of the positive pressure (as shown in Figure 2), so that the water or gas in the hollow elastic ball 1 does not leak through the vent hole 2, and the effect of pressure increase is achieved. When the squeezed hollow elastic ball 1 is released, the air pressure in the ball is less than the outside, and the light ball 22 is opened under the action of the external air pressure or gravity, and the air outside the ball is sucked into the ball through the vent hole 2 to make the ball rebound and restore, so as to squeeze the hollow elastic ball 1 again, so as to realize continuous and multiple squeezing actions for unblocking, without the need for left and right hand coordination to achieve continuous squeezing and releasing of the hollow elastic ball 1 for effective unblocking until the blockage is removed or dispersed. Compared with the traditional tea tray drainage accessory, it is more convenient and effective to dredge, and the structure is simple and convenient for production.

[0044] In order to achieve better unblocking force, and the generated positive pressure can act on the tea dregs and foreign matter, prevent water or gas from leaking from the drainage channel of the unblocked end, when the hollow elastic ball 1 is squeezed to unblock, the drainage channel of the unblocked end needs to be blocked, so that water or gas cannot pass through. The unblocked end of the drainage hose can be manually bent to block it, or a switch valve can be provided on the first drainage channel 3 and the second drainage channel 4 to close the drainage channel of the unblocked end during unblocking operation.

[0045] Second embodiment, refer to Figures 3-4 .

[0046] A different setting method of the vent hole 2 provided with a valve assembly in the first embodiment is provided.

[0047] In this embodiment, based on the structure of the vent hole 2 provided with a valve assembly in the first embodiment, the vent hole 2 provided with a valve assembly is arranged on the hollow elastic ball 1. The vent hole 2 provided with a valve assembly is arranged on the upper half of the hollow elastic ball 1, close to the water inlet end. Under the premise of the normally open vent hole, when the water in the hollow elastic ball 1 fills the air passage 21, the water can lift the light ball 22 to close the vent hole 2, achieving the effect of preventing water overflow.

[0048] When the drainage is normal, the light ball 22 falls on the support 23 (such as Figure 3 ), the vent hole 2 is opened, so that the inside of the hollow elastic ball 1 and the drainage channel are in communication with the atmosphere, and the drainage is smoother. When the first drainage channel 3 or the second drainage channel 4 is blocked by tea dregs or foreign matter during the drainage process, the second drainage channel 4 or the first drainage channel 3 of the other end of the hollow elastic ball 1 which is not blocked can be manually blocked (the drainage hose of the other end of the hollow elastic ball 1 which is not blocked can be pinched or folded to close), and then the hollow elastic ball 1 is squeezed, so that a large positive pressure is generated in the hollow elastic ball 1 to impact the tea dregs and foreign matter, and the unblocking is achieved. With the hollow elastic ball 1 being squeezed, the light ball 22 closes the vent hole 2 under the action of the positive pressure (such as Figure 4), so that the water or gas in the hollow elastic ball 1 does not leak from the vent hole 2, and the effect of pressure increase is achieved. When the squeezed hollow elastic ball 1 is released, the air pressure in the ball is less than the outside, and the light ball 22 is opened under the action of external air pressure or gravity, and the air outside the ball is sucked into the ball through the vent hole 2 to make the ball rebound and restore, so as to squeeze the hollow elastic ball 1 again. Without the coordination of the left and right hands, the hollow elastic ball 1 can be squeezed and released continuously many times to effectively dredge until the blockage is discharged or dispersed. Compared with the traditional tea tray drainage accessory, the tea tray drainage accessory is more convenient and effective.

[0049] In a third embodiment, with reference to Figures 5-6 .

[0050] The embodiment provides a tea tray drainage accessory for realizing drainage of a tea tray device. The tea tray drainage accessory comprises a hollow elastic ball 1 and a first drainage channel 3 and a second drainage channel 4. One end of the first drainage channel 3 is communicated with a water inlet end of the hollow elastic ball 1, and one end of the second drainage channel 4 is communicated with a water outlet end of the hollow elastic ball 1. The tea tray device comprises a tea tray provided with a drainage port and a tea tray drainage device, and the tea tray drainage device comprises a sewage bucket or a sewer. One end of the first drainage channel 3 is communicated with the water inlet end of the hollow elastic ball 1, and the other end is communicated with the drainage port of the tea tray. One end of the second drainage channel 4 is communicated with the water outlet end of the hollow elastic ball 1, and the other end is communicated with the sewage bucket or the sewer. The first drainage pipe 31 and the second drainage pipe 41 are drainage hoses. The hollow elastic ball 1 can be integrally arranged with the drainage hose, or one end of the first drainage pipe 31 is communicated with the water inlet end of the hollow elastic ball 1 through a first pipe joint 32, and one end of the second drainage pipe 41 is communicated with the water outlet end of the hollow elastic ball 1 through a second pipe joint 42.

[0051] The tea tray drainage accessory is provided with a vent hole 2 (such as Figure 5 ) provided with a valve assembly at the first pipe joint 32 of the first drainage channel 3. The vent hole 2 provided with the valve assembly is normally closed. In a natural state, the valve assembly closes the vent hole 2. When the hollow elastic ball 1 is squeezed, the vent hole 2 is also in a closed state. When the hollow elastic ball 1 is released after being squeezed, the hollow elastic ball 1 rebounds and restores, and when the negative pressure in the ball reaches a certain degree, the valve assembly opens the vent hole 2, so that the air outside the ball is sucked into the inside of the ball through the vent hole 2.

[0052] Specifically, the vent hole 2 comprises an air passage 21, and the valve assembly is a one-way air nozzle valve 24 arranged at an air inlet of the air passage 21. When normally draining, the vent hole 2 is closed (such as Figure 5), when the first drainage channel 3 or the second drainage channel 4 is blocked by tea dregs or foreign matters during the drainage process, the other end of the drainage hose not blocked can be squeezed or folded to close the drainage channel of the end not blocked, the hollow elastic ball 1 is squeezed, a larger positive pressure is generated in the hollow elastic ball 1 to impact the tea dregs or foreign matters, the blockage is removed, during the squeezing process of the hollow elastic ball 1, the vent hole 2 is always closed, and the water or air in the hollow elastic ball 1 cannot leak through the vent hole 2. When the squeezed hollow elastic ball 1 is released, the one-way air nozzle valve 24 is opened (for example Figure 6 ), the air outside the ball is sucked into the ball through the vent hole 2 to make the ball rebound and restore, so as to squeeze the hollow elastic ball 1 again, the hollow elastic ball 1 can be continuously squeezed to remove the blockage for multiple times, the hollow elastic ball 1 can be continuously squeezed and released to effectively dredge for multiple times without the coordination of the left and right hands, until the blockage is removed or dispersed, and the traditional tea tray drainage accessory is more convenient and effective to dredge.
