Description

Gas safety switch

This creation is related to a safety switch, especially a gas safety switch installed on the gas pipeline to provide intelligent automatic blocking and closing gas function.

Gas appliances (gas stoves, gas water heaters, etc.) are the necessary cooking or heating appliances for the general family. Although they bring great convenience to people, they often occur after cooking food, because they are not negligent, they do not turn off the fire. Run to deal with other things or go out, causing the food in the pot to dry, become empty and super hot, and lead to fire. In addition, it often happens when the bath suddenly becomes unwell or forgets to shut off the water, causing the gas water heater to continue burning. Not only wastes gas and water resources, but also easily releases a large amount of gasified carbon and causes poisoning.

Therefore, in recent years, the industry has developed a gas timing switch, such as Announcement No. M255379 "Gas Furnace Time Switch" Announcement No. 553361 "Gas Furnace Automatic Shutdown Timer", Announcement No. 529699 "Self-assemblable Gas Furnace Switch Timing Device", Announcement No. 344444 "Safe Gas Burner with Timed Music Alert", Announcement No. 353510 "Mechanical Timing Control Device for Gas Burning Furnace", Announcement No. 433439 "Safe Gas Burner with Timing" and Announcement No. 443474 The new patent case, such as "Gas Furnace Timing Valve Device Structure Improvement", is used to provide timing control to automatically shut off gas. However, these conventional gas timing switches, whether integrated with the fire switch or separate structural design, must be shipped by the manufacturer before the gas stove is shipped. It has been assembled by professionals. Therefore, the gas burner switch originally used by consumers does not have a timing function. If the gas stove is equipped with the function of automatically shutting down the furnace timing, it is necessary to discard the existing gas furnace and replace it with another one. The new gas stove that automatically turns off the fire, this way is a waste for consumers. Secondly, some of the conventional gas-timed gas-fired furnace switches are combined with one-piece linkage, and do not have the structure of the clutch control, that is, the user does not set the furnace closing time, and only operates the gas furnace switch to control the gas furnace fire, the gas timing The switch will also be activated at the same time, and since people cook the food during this time, they only work in the kitchen, or simply heat the leftovers, and do not need to be specially set. Therefore, the gas timing switch is The start-up causes great inconvenience to the user, and the gas-fired switch and the size knob of the gas furnace are often rotated, so that the gas timing switch is driven to perform unnecessary actions, which makes the components in the gas timing switch easy. Loss, but there is a short service life, in addition, some of the known gas timing relationship is set by independent individuals, allowing the user to choose whether to turn off the fire regularly, thereby reducing the gas timing switch is driven. Make unnecessary actions, but do lose the automatic function, but still prone to cooking after cooking, due to negligence, not closed The fire will go out or deal with other things, lead to the pot boil dry food, become super-heated air burning, causing a fire, poor practicality.

The creator has a gas safety switch, which can only be installed by a professional in a specific gas furnace, and does not have the function of intelligent automatic control, which causes inconvenience and limitation in use. The idea, after many discussions and trial sample tests, and many revisions and improvements, 遂 launched this creation.

This creation provides a gas safety switch for installation on a gas pipeline. The utility model comprises: a channel, an opening and closing valve, a detecting device, a controller and a timer, wherein the channel has an inlet connected to the gas source and an outlet connected to the gas conveying destination, and the opening and closing valve is used To open or block the channel, the detecting device is configured to detect a gas change of the channel, and the gas change may be a change of various data such as a gas flow rate and a flow rate, and the controller and the opening and closing valve and the detecting device The electrical connection is configured to receive the signal transmitted by the detecting device and the feedback signal to the opening and closing valve, and is configured to set a set time, and the timer is electrically connected to the controller for providing a timing function, the timer Another time can be electrically connected to a time display and a time setter; thereby, when the gas change through the channel remains unchanged until the set time, the controller immediately controls the opening and closing valve to close the channel, automatically blocking the closing of the gas, and During the timing, when the gas passing through the channel changes in flow rate or flow rate, it is re-timed.

The main purpose of this creation is that it is assembled on the gas pipeline and is easy to assemble, and can be assembled and used by itself and applied to any gas appliance, and the scope of use and ease of use are improved.

The second purpose of this creation is to provide a smart automatic blocking and shutting off gas by detecting gas changes, which has better practical effects.
