[0002] A coffee machine is a household appliance or commercial appliance that automatically makes coffee, including the entire process of grinding, pressing, filling, brewing, and removing residues. Some of these coffee machines are equipped with a hot water steam function, and the hot water steam is switched on and off through a steam control switch on one side of the machine body. For example, the application number 201020514285.8 disclosed in the Chinese patent literature, the authorization announcement date 2011.04.20, the utility model name "coffee machine steam volume adjustable conversion valve", the coffee machine steam volume adjustable conversion valve includes a steam valve body, a steam valve cover and a knob switch assembly, the knob switch assembly is sealed and connected to the steam valve body, a steam regulating component is provided between the steam valve cover and the knob switch assembly, and the knob switch assembly is rotatably connected to the steam regulating component. However, when the steam switching valve or steam switch knob of the above-mentioned product and similar products is rotated for use, it is difficult to trigger the corresponding micro switch to realize real-time monitoring of the switch state; at the same time, the method of using a water pump inner push rod to realize the above switch state monitoring and micro switch triggering is rarely used. Summary of the invention

[0003] In order to overcome the above shortcomings, the purpose of the utility model is to provide a coffee machine steam control switch valve device to the art, so as to solve the technical problem that the steam switching valve or steam switch knob of the existing similar products is difficult to trigger the corresponding micro switch to achieve real-time monitoring of the switch state when rotating; at the same time, it is less likely to use the push rod inside the water pump to achieve the above switch state monitoring and micro switch triggering. The purpose is achieved through the following technical solutions.

[0004] A coffee machine steam control switch valve device, a valve frame and a pump frame are provided on one side of the bottom frame of the device, one end of the knob switch is arranged on one side of the valve frame of the bottom frame for rotation, a water pump is fixedly arranged on the outside of the pump frame of the bottom frame, a steam pipe interface and a steam inlet are arranged in the pump frame of the bottom frame, and a valve plug of the water pump is arranged between the steam pipe interface and the steam inlet to realize switch switching through a spring. The key points of its structural design are that a push rod is provided in a channel on one side of the valve plug of the water pump, one end of the push rod extends out of the water pump and the pump frame of the bottom frame, and a sealing ring is provided on the outer diameter of the push rod in the water pump; when the push rod abuts against one end of the arc rib protruding at one end of the valve frame of the knob switch, the other end of the arc rib of the knob switch abuts against the spring of the micro switch at the same time and triggers the micro switch. Therefore, when the knob switch is turned on to use steam hot water, the push pin is pushed out and the knob switch triggers the micro switch; when the knob switch is turned off to turn off steam hot water, the push pin is reset and the knob switch does not trigger the micro switch.

[0005] The valve plug and the push rod of the water pump are integrally formed, so that the pipeline at the water pump of the device adopts a three-way structure design.

[0006] The arc rib of the knob switch is an eccentric cam edge protruding on one side of the outer diameter of the bottom of the knob switch, so as to facilitate the arrangement of another micro switch.

[0007] The bottom sleeve of the rotary switch is symmetrically provided with raised limit ribs on both sides of the ring, and the limit ribs are respectively aligned with the two sides of the micro switch or the inner limit column to be against and limited, and the inner limit column is arranged on one side of the housing of the micro switch or the bottom frame of the micro switch, and the bottom sleeve of the rotary switch rotates synchronously with the rotary switch. Therefore, when the push rod abuts against one end of the arc rib raised at one end of the valve frame of the rotary switch, and the other end of the arc rib of the rotary switch abuts against the spring of the micro switch and triggers the micro switch, the limit rib on one side of the rotary switch abuts against one side of the micro switch for limit; on the contrary, when the push rod falls off the arc rib of the rotary switch, the limit rib on the other side of the rotary switch abuts against the other side of the micro switch for limit.

[0008] The pump frame of the base frame is arranged on one side of the valve frame and connected at a right angle, thereby facilitating the utilization and reduction of the overall space of the device.

[0009] The utility model has reasonable structural design, small volume, convenient production, installation and use, good stability, and convenient real-time monitoring of switches; it is suitable for use as a steam control switch valve device for coffee machines, as well as a structural improvement of similar products.
