The components of the furnace burner are conveniently assembled and designed, so that the burner head is positioned inside the sealing front cover, a good windproof protection effect is achieved, meanwhile, a multi-stage rotational flow structure is designed, air and fuel gas respectively generate strong rotational motion through the multi-stage rotational flow blades after entering the burner, and the burner head is prevented from being blocked by the multi-stage rotational flow blades. Air and fuel gas can be mixed more sufficiently, the combustion efficiency is improved, the flame stabilizing disc is arranged in the combustor, combustion of flames can be stabilized, flame blow-off or backfire is prevented, and stability and safety in the combustion process are ensured.

The invention relates to a high-reliability ignition control system based on a dual-detection dual-drive mechanism, and belongs to the technical field of hardware circuit design. The test system receives a data stream signal sent by the PC monitoring system through a serial port cable and then sends a response data transmission signal to the high-reliability ignition control system through a communication cable; the high-reliability ignition control system carries out power supply identification signal detection and state identification signal detection, if the high-reliability ignition control system supplies power to a battery and is in a release state, an ignition control process is started, and an ignition voltage signal is fed back to the test system through a communication cable; otherwise, ignition control is not carried out; the test system processes the ignition voltage signal to obtain an ignition voltage value, and inputs the ignition voltage value to the PC monitoring system for display; and the ignition control adopts a double-switch control mode of an electromagnetic relay and a solid relay to realize short circuit and disconnection of an ignition circuit so as to ensure accurate control and high reliability of ignition. The device has the advantages of high safety, high reliability, multi-path ignition control, mistaken ignition prevention and the like.

This invention provides a combustion device, its ignition control method, and a readable storage medium. The ignition control method includes: acquiring a fan power-speed curve and the actual fan speed under constant airflow conditions, and obtaining a target fan power based on the curve and the actual fan speed; acquiring the actual fan power and actual temperature, and obtaining a fan compensation power based on the actual fan power and actual temperature; comparing the target fan power and the compensation power, and adjusting the fan speed when there is a deviation between the target power and the compensation power; and performing an ignition operation when the deviation between the target power and the compensation power is within a predetermined range. This method can improve the ignition success rate.

This invention provides a safe automatic injection pen, including a pen body sleeve, an actuator, an activation sleeve, and a push rod. A button is located at the distal end of the pen body sleeve, and a needle cover is located at the proximal end. The actuator is disposed within the pen body sleeve, with one end connected to the button and the other end having a protrusion. The activation sleeve is fitted over the actuator, and the push rod is disposed inside the actuator, with an annular groove on its outer wall engaging with the protrusion of the actuator. When the needle cover presses against the injection site, the activation sleeve moves a first displacement H1 relative to the actuator in a direction away from the needle. When the button is pressed, the actuator moves a second displacement H2 relative to the activation sleeve in the direction of the needle. When both the first displacement H1 and the second displacement H2 occur, the protrusion separates from the annular groove to release the plunger spring, allowing the push rod to drive the rubber stopper to move towards the needle to complete the injection. This effectively reduces the risk of accidental injection due to accidental button press, accidental impact, or unintended user operation.

The utility model provides a burner for a stove, and belongs to the technical field of gas stoves. The burner comprises a small fire hole channel used for fire outlet, the small fire hole channel is designed to comprise a first small fire hole channel body serving as an air inlet section and a second small fire hole channel body serving as an air outlet section, and the sectional area of the first small fire hole channel body is designed to be smaller than that of the second small fire hole channel body; in this way, the problem of fire blow-off during fire outlet of the soft fire hole channel can be prevented.

The application relates to a gas stove and a burner thereof. The burner comprises an ejector pipe group and a damper end plate. The ejector pipe group has an air inlet end and an air outlet end, and a booster hole is arranged in the side wall of the ejector pipe group close to the air inlet end; the damper end plate is arranged at the air inlet end of the ejector pipe group, and a primary air inlet hole and a gas hole are arranged in the damper end plate. External air can be sucked into the ejector pipe group through the booster hole and the primary air inlet hole at the same time, the booster hole is used for increasing the air intake amount, facilitating further promotion of combustion, improving the combustion efficiency and reducing the CO emission amount. The booster hole is arranged in the side wall of the ejector pipe group close to the air inlet end, and the primary air inlet hole is arranged on the damper end plate, that is, the air flow direction of the air entering from the booster hole is different from the air flow direction of the air entering from the primary air inlet hole. Therefore, when the two air flows flow into the ejector pipe group at the same time, the two air flows collide and mix, the air and the gas are fully mixed, the combustion efficiency is improved, and the CO emission amount is reduced.
