Problems solved by technology

[0004] However, due to the frequent switching of the liquid / vapor circuit in the beverage machine, there are high requirements for the wear resistance and rigidity of the valve for liquid / vapor circuit switching. In response to these requirements, combined with Malta's own cross drive structure characteristics , the driving pin in the device is made of metal material as the driving pin shaft, and the base is made of plastic parts. Reduce the cost of materials, but the requirements for the production process will be correspondingly improved, and the corresponding production process will be more complicated; in addition, due to the frequent switching of the waterway in the beverage machine, the beginning and end of the drive pin rotation, Acceleration changes greatly, there is flexible impact, and it is prone to wear, and this wear will increase exponentially with the generation of wear, which cannot meet the high-frequency use scenarios and long-term life requirements; in addition, due to the Maltese cross The cooperation between the drive pin and the sheave in the disk, one is made of metal material, and the other is made of plastic material, the strength of the two materials is not consistent, when there is a gap due to wear, it is easier to generate noise when the meshing and meshing impact occurs, which affects the experience of using the beverage machine sense

specific Embodiment 1

[0033] This embodiment provides a diverter valve, including a diverter valve assembly, a diverter valve transmission member, a drive motor and a control device for controlling the drive motor, and the drive motor drives the drive motor under the control of the control device. The transmission of the diverter valve transmission assembly, and then drives the gradual positioning of the diversion valve assembly. It is characterized in that, the said diversion valve transmission assembly is an intermittent gear transmission assembly, and the intermittent gear transmission assembly is driven by the drive motor. Every transmission at least once, the control device will control the driving motor to stop driving.

[0034] The intermittent gear transmission assembly includes a driving wheel and a transmission wheel meshing with each other, the driving wheel is connected to the driving assembly, the transmission wheel is connected to the diverting valve assembly, and each time the driving...

specific Embodiment 2

[0055] The difference between this embodiment and the specific embodiment 1 lies in that the structure and transmission mode of the driving wheel and the transmission wheel in the intermittent gear transmission assembly in this embodiment are different.

[0056] In this embodiment, the disc-shaped boss area on the driving wheel is at the same height as the driving teeth in the driving tooth area. The drive gears are gear teeth meshing with the drive gears. After the drive gears on the drive wheel have driven their corresponding set of drive teeth, the drive gears continue to idle until they return to their original positions.

[0057] Specifically, such as Figure 7 As shown in (a) and 7(b), the intermittent gear transmission assembly in this embodiment includes a driving wheel 21', a split wheel fixing seat 22' and a transmission wheel 23', wherein the split wheel fixing seat 22' is the same as the split wheel fixing seat 22 in the specific embodiment 1, and will not be desc...

specific Embodiment 3

[0065] This embodiment also provides another exemplary scheme of the intermittent gear transmission assembly.

[0066] In this embodiment, there are a plurality of driving tooth areas on the driving wheel, and the plurality of driving tooth areas are arranged at intervals, and the disc-shaped boss area is intermittently set at the interval between the two driving tooth areas. Inside.

[0067] Specifically, such as Figure 9 As shown in , it is different from the driving wheel 21 in the intermittent gear transmission assembly in the specific embodiment 1, and the driving wheel is the same. The driving wheel in this embodiment is provided with two driving tooth areas, each driving There is one driving tooth in the tooth area, and two intermittent disc-shaped boss areas are arranged between the two driving tooth areas; in detail, the driving wheel 21" in this embodiment is provided with two driving teeth. Teeth 212"a and 212"b, the two driving teeth 212"a and 212"b are opposite...

Abstract

The invention provides a diverter valve which comprises a diverter valve assembly, a diverter valve transmission assembly, a driving motor and a control device for controlling the driving motor. The driving motor drives the diverter valve transmission assembly to transmit under the control of the control device, and then the diverter valve assembly is driven to be positioned step by step; the diverter valve transmission assembly is an intermittent gear transmission assembly, and the control device can control the driving motor to stop driving when the intermittent gear transmission assembly is driven by the driving motor to transmit at least once; and the intermittent gear transmission assembly adopted in the diverter valve is used for transmission in a gear meshing manner, due to the fact that the contact area is large and pressure is small when gears are meshed, transmission is stable and reliable in the action process, abrasion resistance is enough under the high-frequency use condition, and the requirement for long-time work consumption of a beverage machine can be met.

Description

technical field [0001] The invention relates to the technical field of steam / liquid splitting in a beverage machine, in particular to a splitting valve. Background technique [0002] In the prior art, in the field of beverage machines, especially in the field of coffee machines, it is usually necessary to prepare different beverages such as different flavors or types of coffee, and to use different liquids or gases such as milk, milk froth, etc. , hot water or steam, etc. In order to achieve the above purpose, a plurality of one-way valves will be installed inside the ordinary beverage machine, and the one-way valves and functional components such as hot water generators, steam generator hot water outlet nozzles or steam outlet nozzles are controlled manually or automatically by programs. When the function element needs to be used, the one-way valve corresponding to the function element is controlled to open, but the disadvantage of this method is that the number of parts u...
