Ceramic valve with intermediate section for full cold water function

The present invention relates to a ceramic valve, and more particularly to an inventor of an innovative ceramic valve structure having an intermediate section for supplying full cold water.

According to the recent years, the safety of cold and hot double-temperature faucets (hereinafter referred to as dual-temperature faucets) has been highly concerned and valued by relevant industries and consumers. The most important point in its safety appeal project is “anti-scalding”. In view of this, in recent years, related industries have developed a variety of dual-temperature faucet structure types with anti-scalding functions.

The conventional double-temperature faucet structure is generally designed. When the handle is placed in the middle position, if the user raises the handle up at this position, the preset temperature of the water supply is not cold water but mixed with cold and hot water. State, this state of use has been in the design of the dual-temperature faucet product structure for a long time, but we have found that there are some problems in this type of structure; the reason is that if the double-temperature faucet is to be supplied when the handle is pulled In the cold water state, the user can of course achieve this by first turning the handle to the position where the cold water is facing the position and then pulling it up. However, the design consideration of the anti-scalding function obviously has to consider more possibility of scalding. Assume that the user raises the conventional double-temperature faucet handle in the middle position in the case of inadvertent or uninformed (such as children, the elderly, etc.), which is supposedly the warm water state of the cold and hot water. However, there are unstable factors in actual use. For example, if the water supply pressure at the cold water end is weak, it will actually become a hot water mode, and thus there will be burns. The danger of the user exists; in addition, the warm water mode and the hot water mode of the double-temperature faucet are only a few degrees apart from the swinging angle of the handle, and the user turns into hot water when moved slightly or hits. Mode, this is also one of the reasons that may cause burns; on the other hand, when the user raises the handle in the middle position, since the cold and hot water inlet channels are only partially opened, this may also be because of the hot water part. The water pressure is insufficient to reach the standard for igniting gas in the water heater, which is liable to cause gas leakage.

In addition, when the handle of the conventional double-temperature faucet is returned to the position, the user may of course return the cold water to the position facing the side, so that the handle is directly pulled up in the cold water supply state in the next use; However, considering the current situation of use, based on the consideration and cognition of visual aesthetic balance, most users will habitually return it to the middle position after closing the handle of the faucet. This seems to be more pleasing to the eye, especially for For business places such as hotels and homestays that pay attention to service quality and customer perception, when the housekeeping staff sorts the room and bathroom equipment, they are often required to return the handle of the double-temperature faucet to the middle position, so it is necessary to change people. It is quite difficult to return the habit of a pair of warm faucets. Therefore, if the improved design of the internal ceramic valve structure of the double-temperature faucet can be used to overcome the aforementioned problems, it should be an ideal and feasible solution.

Therefore, in view of the problems existing in the above-mentioned two-temperature faucet structure, how to develop an innovative structure that is more ideal and practical, and the users are looking forward to the relevant industry to strive to develop breakthrough goals and directions.
