Ceramic valve with intermediate section for supplying cold water

This creation is about a ceramic valve, especially an innovative structural type revealer of a ceramic valve with a middle section supplying cold water.

In recent years, the relevant industry and consumers have paid great attention to the safety of the use of cold and hot double-temperature faucets (hereinafter referred to as double-temperature faucets), and in the safety appeals, "anti-scalding" is very important among them. Based on this, the related industry has developed a variety of dual-temperature faucet structure types with anti-scalding function, such as setting a blocking structure on the cold and hot water temperature switching path, so that the user wants to switch to the hot water mode. It is necessary to apply a large force to achieve the type design.

At present, the conventional double-temperature faucet structure design visible on the market, when the handle is placed in the middle position, if the user raises the handle upward at this position, the preset temperature of the water supply is not cold water, but A state in which cold and hot water are mixed. When the handle is cocked up in the middle section, it is a mixed water supply state of cold and hot water. Although the structure design and practical application of the dual-temperature faucet have been going on for quite a long time, we have found that this type of structure actually There are some problems and hidden dangers in use. The reason is that if the double-temperature faucet is to supply cold water when the handle is pulled, the user can of course operate by first turning the handle to the position where the cold water is facing the position and then cocked. Ways to achieve, but the design considerations of the anti-scalding function, obviously must be more intimate to consider the possibility of more scald, assuming the user in the middle of the casual or uninformed (such as children, the elderly, etc.) Position up the conventional double-temperature faucet handle, which should be cold The hot water is mixed with the average warm water state, but there are unstable factors in actual use. For example, when the water supply pressure at the cold water end is weak, it will directly become the hot water mode. In this case, there is a scald user. Moreover, 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 may become a hot water mode after slightly moving or hitting, which is also possible. One of the causes of burns; on the other hand, when the user raises the handle in the middle position, the cold and hot water inlet channels are only partially opened, so for the hot water part, it may also be due to insufficient water pressure. It is impossible to reach the standard of igniting gas in the water heater, and thus it is easy to cause the problem of gas leakage.

From another point of view: when the handle of the conventional double-temperature faucet is returned to the position, the user can of course return it to the side of the cold water toward the position, so that the next time it is used, directly upward The handle is the cold water supply state; however, considering the current use situation, based on the consideration and awareness of visual aesthetic balance, most users will habitually return it to the middle position after closing the faucet handle. At this point, it seems to be more pleasing to the eye, especially for hotels, hotels and other commercial establishments 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. In the middle section, it is actually quite difficult to change the habit of locating the pair of warm faucets. Therefore, if the design can be improved from the internal ceramic valve structure of the double-temperature faucet to overcome the above problems. Should be an ideal and feasible solution.

Therefore, in view of the problems existing in the above-mentioned conventional ceramic valve structure, how to develop an innovative structure that is more ideal and practical, is expected by users, and is also related to the industry's efforts to develop breakthrough goals and directions.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

With this innovative and unique design, this creation is compared to the prior art. In other words, an offset type portion of the fulcrum is formed between the rotating driving seat and the connecting seat, and when the brake valve lever is swung to the inclined angle water supply mode at a set intermediate position, the lower end of the brake valve stem is toggled. The end will linearly move the driven groove, and the rotating seat and the rotating valve piece will generate a rotational displacement by using the offset rotary point unit as a pivot point, thereby forming a supply cold water mode in which the water flow control groove system only communicates with the cold water perforation. This allows the ceramic valve to reach the middle section to supply cold water, which is anti-scalding and more in line with the user's practical progress in accommodating the double-temperature faucet handle.
