This invention relates to a sort of intellective gas oven, it consists of the head oven, the control plate, the control keyboard, the portfire and the intellective control valve which is made up of the one that the gas valve and the valve drive the electric engine. The gas valve of the intellective control valve in this invention connects with the head oven and the gas pipe. The gas valve drives in this invention drives this gas valve in this invention which is connects with the electric engine. The control plate connects with the control keyboard and the valve by electricity in order to drive the electric engine. It is characterized in that: this gas valve is a sort of multichanne valve which has an admitting pipe and several escape pipes. The several escape pipes connect respectively with each fire loop of the head oven having several fire loops. The several escape pipes in this invention distribute to each other along the spool arbor of the gas valve, the spool of the gas valve hasthe spool bore which can alter aperture along the circle in turn related to each center of the escape pipe. It has this excellence in that: firepower accommodation with six sects in order to satisfy different require of the cooking method, safe when using, simple and convenient operation, high ignition frequency, no impulse noise when igniting.

The invention provides a radial carbonaceous commutator and a manufacturing method thereof. The radial carbonaceous commutator comprises a cylindrical insulating supporter, a plurality of metal conductor connecting pieces and the same amount of carbonaceous arc-shaped bodies, wherein the carbonaceous arc-shaped bodies enclose to form a carbonaceous cylinder having a plurality of second cutting grooves, the axial end surface on which the plurality of carbonaceous arc-shaped bodies and the plurality of metal conductor connecting pieces are in conductive connection is a closed end surface, the other end of the carbonaceous cylinder is open, an empty cup cavity used for accommodating the supporter is formed between the opening and the closed end surface, a through hole with the diameter less than the inner diameter of the empty cup cavity is formed in the center of the closed end surface, and the plurality of metal conductor connecting pieces are welded and fixed on the closed end surface, in which the through hole is formed, of the carbonaceous cylinder and form a plurality of fan-shaped welding connection surfaces, thereby increasing the welding area between the carbonaceous cylinder and the metal conductor connecting pieces, improving the strength stability of assembly in the axial direction, and guaranteeing the strength requirements required for injection-molding the supporter inside the carbonaceous cylinder.

The invention discloses a protection type frequency converter suitable for new energy main power supply, belonging to the field of frequency converters. The access plug, the left end of the access plug is fixedly connected with the access protection shell located inside the inverter body, the left inner wall of the access protection shell is fixedly connected with the temperature-sensing heat collector, and the access protection shell is fixedly connected with the temperature-sensing heat collector. The temperature-sensing magnetic variable magnetic block on the right side of the chip can be matched with the temperature-sensing heat collector, the temperature-sensing magnetic variable magnetic block, the electrical stability induction component and the fan-type access protection component. The temperature change of the inverter generates induction action, which effectively assists the inverter body to judge the voltage status of the main power supply, improves the functionality and intelligence of the inverter body, effectively reduces the failure rate of various electrical components on the circuit, and promotes new energy. development of.

The invention relates to a power supply pull-board switch, which comprises a switch box, a box cover, a first terminal, a second terminal, a spring leaf and a telescopic mechanism. The spring leaf is in contact with one end of the telescopic mechanism through the second terminal; the telescopic mechanism comprises a guide shell body, a guide pipe, a guide sleeve, a thimble, a compression shaft head, a reset spring, a universal compression cap, a compression spring and a reset spring; the cap edge of the universal compression cap is in contact with the inner wall of the guide shell body; and the cap body thereof is positioned outside the guide shell body. In the invention, the direct contact of a pull wire of the switch with the spring leaf is replaced by the manner that the pull wire is led out of one end of the telescopic mechanism or the universal compression cap is directly turned to control the expansion of the telescopic mechanism, thereby achieving the pulling and turning purposes and solving a series of problems caused by the easy breaking of the power supply pull wire, and the like. In addition, the telescopic mechanism is perpendicular to the spring leaf, so as to ensure the on-off status of the spring leaf and the terminals; when the thimble pushes against the spring leaf or is released, thereby enabling the switch to be operated normally and stably in more complex environment.
