Description

Technical Field

[0001] The invention relates to the field of sanitary ware, in particular to a flow regulating valve core that is easy to use. Background Art

[0002] At present, products in the field of bathroom, such as showers, shower faucets, etc., generally use valve cores to control water channels, and the valve cores are usually divided into valve cores according to user needs and functions, including valve cores for turning water on and off, valve cores for adjusting flow, valve cores for adjusting temperature, valve cores for switching water channels, etc.; however, a set of shower products requires multiple valve cores, and the water channel structure of the main body matched with the valve core is also complicated and large in size, which increases the cost of the product accordingly; therefore, a valve core with multiple functions is needed, such as a valve core that turns water on and off and adjusts flow; however, even if the existing flow regulating valve core can achieve very precise flow adjustment, it only adjusts the flow from small to large. When the user needs to adjust the flow rate to a smaller level, such as when washing with hand soap and need to reduce the water flow, he must adjust it back in the opposite direction. In this way, if the user happens to use his non-dominant hand to adjust the flow rate, it is easy to make an error. Even if he uses his dominant hand, he cannot adjust the flow rate by rotating it clockwise or counterclockwise as he wishes. Or, when the flow regulating valve core is used in the shower, it can only adjust the flow from small to large without obvious gears. If the user wants a small water level for children to play in the water, or a medium flow rate for a softer and more comfortable flush, or a large flow rate for a comfortable flush, it is difficult to control it properly. Obviously, the flow regulation function of the existing flow regulating valve core is very inhumane. Summary of the Invention

[0068] The working principle of the present invention is briefly described as follows:

[0069] When the pressure regulating member 2 is rotated within the limited range, the regulating member 2 is rotated until the water inlet 71 and the regulating hole 21 generate an overlapping flow cross-sectional area, and water can flow through the regulating member 2. When the pressure regulating member 2 is rotated further toward the middle of the limited range, the overlapping flow cross-sectional area continues to increase linearly, and the water flow increases with the pressure regulating member 2. The linear increase is convenient for user use and flow adjustment; when the adjusting member 2 is continued to be rotated, the flow cross-sectional area becomes smaller, and the water flow decreases linearly accordingly; at one end of the limited range, the water flow cross-sectional area is the smallest, the middle section is the largest, and the other end is the smallest or half of the maximum water flow cross-sectional area or other flow rate, which is subject to the setting of each embodiment, but the range of each water flow cross-sectional area is the scope protected by the present invention; when the valve core is opened and the water flow cross-sectional area is just at the maximum, the adjusting member 2 can be rotated in either direction to reduce the flow rate; when the limited range is 360 degrees, when the water flow cross-sectional area is just at the minimum flow rate, the adjusting member 2 can be rotated in either direction to increase the flow rate; when it is determined that no water is needed, the valve core can be closed; the operation of closing the valve core has been stated above; and when the valve core switch is turned on and a quantitative water discharge is required, it only needs to be rotated left or right to the end to achieve blind adjustment.

[0070] The water flows through the overlapping flow cross-sectional area generated by the adjusting hole 21 on the adjusting member 2 and the water inlet hole 71 on the base 7, and the flow cross-sectional area generated by the adjusting hole 21 and the water inlet hole 71 is gradually enlarged and then continuously reduced by rotating the adjusting member 2, thereby achieving precise adjustment of the water flow rate. In addition to being able to adjust the flow rate from small to large, the user can also rotate the direction of the adjusting member at will to change the flow rate from large to small; the fixed values ​​of the flow cross-sectional area at the initial end and the flow cross-sectional area at the end make it easy for the user to control the water-saving gear or the comfort gear, And when the regulating part is rotated to the middle section, it is easy to obtain a large flow of water for flushing; when the user is in use, he turns on the water inlet, but the water outlet position is not fixed each time and can stay at any position. At this time, it is not easy for the user to adjust the flow rate he wants to use. However, when using the flow regulating valve core of the present invention, there is no need to look at the adjustment mark. When it is rotated to the left or right to the end, water will be discharged in a quantitative manner, realizing blind adjustment, which is very suitable for user needs; the present invention has a simple structure and will not be stuck due to wear of various components, which will make the valve core unable to realize the adjustable function of the flow rate.
