Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] like Figure 1~4 Shown is a preferred embodiment of the present invention.
[0026] A joint installed on the water tank seat of the coffee machine, including a joint body for connecting with the water outlet of the water tank, the water tank is not shown in the drawings. The joint body in this embodiment includes a sleeve 1, a socket 2 and a sealing ring 3. The cross section of the sleeve 1 is roughly circular, and the upper part of the inner peripheral wall of the sleeve 1 has an annular stop extending inward. 11. The lower end surface of the sleeve 1 has four elastic clips 12 extending downward and arranged at intervals.
[0027]The shape of the connector 2 matches the sleeve 1 and can be inserted into the sleeve 1 . The connector 2 has mounting parts 10 extending outward on both sides, and mounting holes 101 are opened on the mount...

The invention relates to a connector installed on a water tank seat of a coffee machine. The connector comprises a connector body which is provided with a cavity. A top pillar is arranged in the middle of the cavity. A water outlet channel and a water return channel are formed in a connector clip. The connector is characterized in that a filtering piece provided with filtering holes is further arranged in the cavity, the filtering piece is sleeved on the top pillar, the cavity is divided into an upper cavity and a lower cavity by the filtering piece, the water outlet channel and the water return channel are independent, an inlet of the water outlet channel is communicated with the lower cavity of the cavity, the water return channel extends upwards into the top pillar, and an outlet of the water return channel is formed in the side wall of the top pillar and is communicated with the upper cavity of the cavity. Return water flows out from the water return channel arranged on the top pillar and enters into the upper cavity of the cavity, certain surface tension is formed in the filtering holes of the filtering piece by the water flow, if flow of the return water is not big enough for passing through the filtering piece, the return water can be prevented from passing through a flow meter directly, the flow meter can sense water shortage, and then the machine is immediately stopped so as to avoid pumping of a water pump.
Description
technical field [0001] The invention relates to a joint, in particular to a joint installed on a water tank seat of a coffee machine. Background technique [0002] As a beverage extraction device, a coffee machine generally includes a water supply part and an extraction part, and the water supply part is used to provide hot water for the extraction part. The water supply part mainly includes a water tank and a water tank seat. The water tank is a container for holding water. The water tank is placed on the water tank seat. There is a water outlet at the bottom of the water tank. Non-return valve for closing outlet tendency. [0003] A joint with a water outlet channel is installed in the water tank seat, and the middle part of the joint has a top column extending upwards. When the water tank is installed on the water tank seat, the top post in the middle of the joint pushes up the water tank valve, allowing the water in the water tank to be connected to the water tank seat....
