Description

[0002] In traditional water dispensers, the high water pressure of raw water needs to be converted into low water pressure or no water pressure. Usually, the following two methods are used: 1. Water supply from a water tank; 2. Water supply from a mechanical negative pressure valve.

[0003] Among them, the water tank water supply method is difficult to use in commercial occasions due to the small capacity of the water tank; at the same time, it is necessary to set up additional one-way valves, water pumps and other accessories to cooperate with liquid level switches or float valves to control the water level height, temperature, and flow rate, which has a complex structure and high cost;

[0004] The mechanical negative pressure valve water supply is a mechanical negative pressure valve and a water pump working together. The water pump generates negative pressure at the water outlet of the mechanical negative pressure valve to open the mechanical negative pressure valve, thereby realizing the water supply of the water dispenser; when the water pump stops working, the negative pressure disappears, the mechanical negative pressure valve closes, and stops supplying water to the water dispenser, playing a role of intercepting flow. However, the switching action of the mechanical negative pressure valve in the prior art is affected by water pressure and flow, and has disadvantages such as large jitter, large noise, and current limitation.

[0005] Both of the above methods involve water connection of multiple modules. Too many connection positions not only complicate the assembly process of the water purifier, but also reduce the assembly efficiency.

[0044] The valve chamber includes a first flow channel 11 and a second flow channel 13 connected to each other, and a constant pressure and constant current component is arranged between the first flow channel 11 and the second flow channel 13.

[0045] The valve body 1 is provided with a water outlet seat 14 , which is provided with a first flow inlet 141 connected to the second flow channel 13 and a flow outlet connected to the water outlet. The water outlet seat 14 is connected to a flow regulating module for regulating the outflow flow of the flow outlet.

[0046] Through this arrangement, a flow detection component is arranged at the water inlet of the valve body to monitor the water inlet flow in real time, a constant pressure and constant current component is arranged in the valve cavity of the valve body to realize a second flow channel, and a flow regulating module for regulating the outlet outflow flow is arranged on the water outlet seat.

The magnet 62 is installed on the impeller and rotates synchronously with the impeller. The electromagnetic induction element 63 is installed on one side of the flow meter installation channel and obtains a fluid flow signal by rotating the induction magnet 62.

[0050] Through this setting, the purpose of real-time and accurate detection of the flow rate at the water inlet of the valve body can be achieved. In this embodiment, the electromagnetic induction element 63 is specifically selected as a Hall sensor, and the electromagnetic induction element can be connected to the control element by electrical signals.

[0052] Through this arrangement, the center limit shaft has a positioning effect on the impeller, which not only improves the stability of the connection between the impeller and the flow meter installation channel, but also realizes the easy disassembly and assembly of the two. At the same time, the magnet is installed on the rotating seat located away from the end of the center limit shaft. This position makes the magnet less susceptible to the impact of water flow, improves its service life, and shortens its distance from the electromagnetic induction element, further improves the accuracy of the induction, and the overall volume of the flow detection assembly. In this embodiment, two magnets are specifically provided and are respectively located on both sides of the rotation center of the rotating seat.

[0055] The second flow inlet 811 corresponds to the axis of the rotating disk 82. A radial communication groove 821 is provided on a surface of the rotating disk 82 that is in contact with the fixed seat 81, one end of which is located at the rotation center of the rotating disk 82 and is radially arranged.

[0056] The flow regulating groove 812 extends circumferentially along the first direction A and its radial width gradually increases. The depth of the flow regulating groove 812 is consistent at all locations. The first communication port 8121 is located at the end of the flow regulating groove 812 in the first direction A.

[0057] Through this arrangement, the flow rate of the first water outlet can be adjusted steplessly, which improves the flexibility of the combined valve in adjusting the flow rate. In this embodiment, the flow regulating groove is specifically in the shape of a water droplet, with a smooth transition at the end, which reduces ditch siltation and resistance to the fluid.

[0060] The flow regulating module further includes a driving motor 91 disposed on the valve body 1 and a transmission mechanism connected between the driving motor 91 and the flow regulating component.
