Description

[Technical field]

[0001] The present invention relates to the technical field of coffee drip pots and teapots, and in particular to a water flow control valve for the pot. [Background technology]

[0002] When brewing hand drip coffee and tea leaves, there are certain requirements for the amount of water flow, so it is extremely important to have a pot that can adjust the amount of water flow.

[0003] For example, the teapot disclosed in the Chinese Utility Model No. 201620539259.8 has an existing teapot structure including a teapot body and a fixed base. The teapot body has a spout and a handle on both sides, a lid and a handle on the top of the teapot body, and a teapot base on the bottom of the teapot body. The teapot base is provided with an automatic temperature control system, which includes a temperature control device, a heating device, and a switch, and a metal heat-conducting plate on the top of the automatic temperature control system. The teapot base has a locking piece on both sides of its edge, and a locking groove is provided in the fixed base to lock with the locking piece. A support is provided on the bottom of the fixed base, and a vacuum suction cup is provided at the end of the support. In use, the automatic temperature control system can ensure that the tea in the teapot is always in a relatively high temperature state, and when the temperature control device detects that the temperature of the tea in the teapot body is relatively low, the temperature control device controls the heating device to continue heating. When the temperature rises to a certain value again, the temperature control device controls the heating device to stop heating, and so the cycle repeats.

[0004] However, the existing coffee drip pots and teapots on the market cannot adjust the water flow rate when brewing hand drip coffee or tea with tea leaves, and the water flow rate is controlled by adjusting the tilt angle of the pot body. It is difficult for beginners to control the water flow rate when brewing coffee or tea. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] China Utility Model No. 201620539259.8 Specification Summary of the Invention [Problem to be solved by the invention]

The fixing mechanism is attached to the pot to prevent the device from flooding, the control mechanism is attached to the fixing mechanism to move the closing mechanism, the adjustment mechanism is attached to the control mechanism to rotate the control mechanism, and the closing mechanism is attached to the fixing mechanism to control the outflow rate. When a user needs to pour, he rotates the adjustment mechanism, which rotates the control mechanism, and the control mechanism moves the closing mechanism to adjust the closing area of ​​the closing mechanism, which makes it convenient to adjust the outflow rate. The installation of the fixing mechanism prevents the water flow from affecting the control mechanism, and extends the service life of the device.

The water flow adjustment knob is fitted to the sealing base fixing nut, and the water flow adjustment knob metal case is fitted to the outside of the water flow adjustment knob. When a user twists the water flow adjustment knob metal case, the water flow adjustment knob metal case rotates the sealing ring 2 and the sealing base fixing nut, and the sealing base fixing nut rotates the adjustment shaft. The installation of the gasket and the sealing ring 2 enhances the waterproof sealing effect.

[0012] Preferably, the closing mechanism includes a driven gear shaft, a driven gear, and a water flow adjustment piece. The driven gear shaft is rotatably mounted on the fixed base, and the driven gear is mounted on the driven gear shaft to mesh with the driving gear to transmit. The water flow adjustment piece is slidably mounted in the slide groove of the pouring pipe sealing silicone rubber, and a tooth groove is provided at the top of the water flow adjustment piece to mesh with the driven gear. The driving gear rotates the driven gear and the driven gear shaft, and the driven gear moves the driven gear shaft up and down. This adjusts the area where the water flow adjustment piece closes the through hole of the pouring pipe sealing silicone rubber, thereby realizing the control of the water outflow rate. Furthermore, the transmission ratio is changed by adjusting the gear ratio of the driven gear and the driving gear. The water flow adjustment knob metal case can be rotated one revolution to adjust the water outflow rate from minimum to maximum. Effect of the Invention

[0013] The beneficial effects of the present invention compared with the existing technology are as follows: When the user needs to pour, he rotates the adjustment mechanism, which rotates the control mechanism, which moves the closing mechanism to adjust the closing area of ​​the closing mechanism, which is convenient for adjusting the water flow rate; the installation of the fixing mechanism prevents the water flow from affecting the control mechanism, which extends the service life of the device.
