| 20090027216 | OXYGEN SENSING DEVICE - The oxygen sensing device contains a power circuit supplying the electricity required, an oxygen sensor for detecting the oxygen concentration in the atmosphere, an alarm system issuing an audible or visual alarm signal, and a controller. The controller is a computing device having a preset threshold value that continuously obtains the current oxygen concentration from the oxygen sensor. The controller then can calculate and obtain the variation rate of the oxygen concentration in a unit time. If the controller detects that the current oxygen concentration is about to drop below the threshold value, it will activate the alarm system to issue an alarm to alert people to take immediate and proper action. | 01-29-2009 |
| 20090206291 | GAS FLOW RATE CONTROL VALVE - A gas flow rate control valve includes a lower valve block defining a gas flow passage, and an upper valve block having a tube disposed ill communication with the gas flow passage, and a solenoid coil assembly surrounding the tube for generating a magnetic field. A magnetic column has a magnetic portion inserted into the tube and axially movable by the magnetic field generated by the solenoid coil assembly, and a stopper movable with the magnetic portion to change the open cross-sectional area of the gas flow passage so as to control the flow rate of the fuel gas passing through the gas flow passage. A spring member is provided at one of the top and bottom sides of the magnetic column to keep the magnetic column in balance and to provide a return force to the magnetic column after displacement of the magnetic column. | 08-20-2009 |
| 20090272448 | VALVE OF GAS STOVE - A valve of a gas stove includes a valve member and a first sealing member. The valve member is an integral body having a left tube, a right tube, and a connection tube between the left tube and the right tube in a single member. The valve member further has a gas channel therein extended from the left tube, the connection tube to the right tube in sequence and a first bore on the left tube to be communicated with the gas channel. The connection tube has an inlet to be connected to an external gas supply. The first sealing member may be moved to seal the first bore of the gas channel. The present invention has many advantages including strong structure, high precision, and easy for fabrication and assembly. | 11-05-2009 |
| 20110067650 | WATER HEATER MODULE HAVING DETACHABLE HEAT EXCHANGER - A water heater module of the present invention includes a water heater and an extra heat exchanger. The extra heat exchanger has a spiral pipe and is detachably connected to the water heater. The spiral pipe is heated by high temperature gas from the water heater to pre-heat cold water in the pipe, and then the water is sent to the water heater for further heating that the temperature of the water will be raised within a short time. | 03-24-2011 |
| 20110256490 | COMBUSTOR ASSEMBLY OF WATER HEATER - A combustor assembly of a water heater, which is provided between an air blower and a burner set to guide air from the air blower to the burner set, includes a first board, a second board and a third board stacked in sequence. Between the first board and the second board there is a first chamber and a first port, and between the second board and the first board there is a second chamber and a second port. The second board and the third board both have apertures. These boards restrict and divide an air flow of the air blower to flow along several paths to increase heat efficiency. | 10-20-2011 |
| 20110306000 | COMBUSTOR OF WATER HEATER - A combustor of a water heater includes a burner member and a flame cover. The burner member has a passageway therein with an inlet and an outlet. The flame cover has a plurality of flame holes. The character of the present invention is that the burner member is provided with a room at a top thereof communicated with the passageway. A separating device is put in the room, and the flame cover is connected to the burner member to cover the separating device The separating device has a main outlet and two side outlets right under the flame holes of the flame cover to generate main flames and side flames respectively. | 12-15-2011 |
