Abstract:
The present invention provides a pressure gauge for measuring a pressure of a source. The pressure gauge includes a case, a flexible film, a magnetic device, a coil, a processor, and a screen. The case has a bore connecting the source. The coil is provided in the case. The flexible film is provided on an inner side of the case to cover the bore that the flexible film is expandable by the pressure of the source. The magnetic device is received in the case to be moved relative to the coil by the flexible film. The movement of the magnetic device causes the coil to generate an induced electromotive force, and the processor may find the gas pressure according to the induced electromotive force, and show it on the screen.
Abstract:
A water heater includes a combustor, a gas valve, a blower, a detector, and an operating device. The detector senses a speed of a motor of the blower. The operating device is stored with reference speed ranges under various gas supplies to control the gas valve to cut off the gas supply when the detector senses that the speed of the motor of the blower is beyond the reference speed range
Abstract:
An enclosure structure of water heater is disclosed, which is readily assembled/disassembled and has an enhanced structural strength, including two opposite side panels having front and rear edges along which aluminum-extruded channels are integrally fixed to respectively receive opposite edges of a front panel and an opposite base plate and top and bottom cover boards respectively attached to upper and lower edges of the side panels to secure the front panel and the base plate in the channels of the side panels. Such a structure enhances simplification of assembling/disassembling the water heater enclosure and provides flexibility in modification of overall outside appearance of the water heater by replacing the side panels and the front panel to thereby eliminate troubles and inconveniences that are encountered in the conventional water heater enclosures.

Abstract:
The present invention provides a method of detecting water heater safety, wherein the water heater includes a blower and a combustor. The method includes starting the blower and detecting blower speed after a certain amount of time; comparing the blower speed with a first speed range, and then supplying gas to the combustor when the speed of the blower is within the first speed range, or providing an alarm when the blower speed is beyond the first speed range; detecting the speed of the blower again after the combustor heats water for a time; comparing blower speed with a second first speed range, and then supplying gas to the combustor when the blower speed is within the second speed range, or stopping gas when the blower speed is beyond the second speed range.
Abstract:
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.
Abstract:
A lamp with heat conducting structure includes a lamp cover made of heat dissipating material. The lamp cover has a hollow configuration therein. An interlayer is horizontally arranged in the lamp cover. The lamp cover is divided into a first space and a second space therein by the interlayer. A LED lamp assembly is disposed in the first space of the lamp cover. A power plug is disposed in the second space of the lamp cover. The power plug has a control circuit board in the second space. The control circuit board has an electronic element disposed thereon. A heat conducting tab protrudes from the interlayer of the lamp cover towards the second space. The heat conducting tab has a heat conducting surface corresponding to the electronic element to thermally contact with the electronic element.

Abstract:
A control valve structure of a gas burner includes a female base, a top base, and a coil base. The control panel energizes the coil base to generate a magnetic field, whereby the magnetic column is displaced upward by the magnetic force of the coil base, so that the main fire electromagnetic valve is acted to let the gas flow into a main fire gas vent, so that the main fire is ignited. The control panel stops energizing the coil base when not in use, whereby the magnetic column is displaced downward to press the push pin, so that the gas cannot enter the main fire gas vent. The displacement can be adjusted finely during the use process, thereby achieving a gas flow rate control with a high safety.
