摘要： A gas valve (122) for a gas appliance of a gas burner system. The gas valve (122) is connected to a gas source (G) via a gas pipe. The gas valve (122) is disposed with a check valve body (30), wherein the check valve body (30) allows gas in the gas pipe to flow into the gas valve (122) and prohibits the gas in the gas valve (122) to flow into the gas pipe. With such design, the check valve body (30) could prevent the gas in the gas valve (122) from flwoing back to the gas pipe. When gas in the gas pipe flows to to another gas appliance of the gas burner system, the gas flowing to another gas appliance does not mix with air in the gas appliance, thereby reducing the iginition time and enhacing the combustion efficiency.

摘要： A gas switching device (1) includes a valve body (10), a switching assembly (28), and a manipulating member (46). The valve body (10) has an inlet portion (12) having an inlet passage (124) and an outlet portion (14) having an outlet port (142) and a receiving chamber having a side opening (202) communicating with the inlet passage (124). The switching assembly (28) includes a plug member (30) located in the receiving chamber. The manipulating member (46) connected to the outlet port (142) via the connecting end (462) drives the plug member (30) to turn between first and second positions (PI, P2). A gas passage (48) of the connecting end (462) communicates with an axial hole (32) of the plug member (30). When at the first position(P1), the plug member (30) closes the side opening (202). When at the second position(P2), the through hole (34) communicates with the side opening (202).

摘要： A combustion device includes a first cover (10), a second cover (20), an infrared generating mesh (30), and a gas burner assembly (40), wherein the first cover (10) has a plurality of through holes (12a). A first half portion (202) of the second cover (20) has at least one hollow portion (22a). A second half portion (204) of the second cover (20) is closed. The infrared generating mesh (30) is disposed between the first cover (10) and the second cover (20). A flame outlet (422) of the gas burner assembly (40) is located within a projection area of the second half portion (204). In this way, the intensity of the infrared rays generated by the combustion device could be increased and could be uniform.

摘要： A method of extending RF signals in a wireless control system which includes a first electronic device (10), a second electronic device (20), and an RF signal extender (30). RF signal coverage areas of the electronic devices partially overlap, and each of the electronic devices is out of the RF signal coverage area of the other one. The RF signal extender (30) is in an overlapping area between the RF signal coverage areas, and the electronic devices are in an RF signal coverage area of the RF signal extender (30). The method includes the steps of: receiving an RF signal with the RF signal extender (30); analyzing the received RF signal to retrieve the data carried therein; and compiling the data into an RF signal for transmission if the retrieved data follows an RF communication protocol of the wireless control system. Whereby, a total RF signal coverage area can be expanded, and interferences can be reduced.
