Abstract: A valve cartridge may include an outer cylindrical body and an inner cylindrical body disposed in a channel formed by the outer cylindrical body. The outer cylindrical body may include a wall that defines the channel. The outer cylindrical body may include a ramped slot. The ramped slot may extend angularly from a first angular position on the wall to a second angular position. The ramped slot may extend longitudinally from a first longitudinal position on the wall to a second longitudinal position. The inner cylindrical body may include a handle interface approximate to a first end of the inner cylindrical body. The inner cylindrical body may include a pin extending radially from the inner cylindrical body and into the ramped slot. The inner cylindrical body may include a valve seat at a second end of the inner cylindrical body.

Abstract: A method is provided for producing a biochar solution. The method comprises the steps of collecting biochar particles, dispersing the biochar particles in a liquid solution and adding a stabilizing agent to keep the biochar in flowable suspension. The stabilizing agent may be added to the liquid solution or to the biochar prior to placing the biochar in solution.

Abstract: A lamp assembly installed to a ceiling fan includes a heat dissipation module and a lamp. The heat dissipation module has a heat dissipation body. The heat dissipation body is mounted to a connecting seat of the ceiling fan. The heat dissipation body includes a plurality of heat dissipation units on one side of the heat dissipation body adjacent to the connecting seat. The heat dissipation units have an axis. The heat dissipation units are sequentially arranged from inside to outside relative to the axis. The heat dissipation units each have at least one heat dissipation fin relative to the axis. The lamp is fixedly connected to another side of the heat dissipation body. The lamp assembly has a better heat dissipation effect and can be installed quickly.

Abstract: A brushless DC motor control device for a ceiling fan is electrically connected to a brushless DC motor and includes at least one switch, a processor, and a driving module. The processor includes at least one detection module and a processing module. The switch transmits a switch signal to the detection module for detection. After the detection module detects an operating electric potential and a normal electric potential of the switch signal, the detection module outputs a detection signal to the processing module. The processing module outputs a control signal to the driving module, so that the driving module transmits a driving signal to the brushless DC motor to control the rotational speed, stop and rotational direction of the brushless DC motor.

Abstract: A fryer includes: an oil tank; and a heater, the fryer being configured to heat a frying oil stored in the oil tank by the heater so as to fry a food material put into the oil tank, the oil tank including an upper oil tank in which the heater is arranged and the food material is to be fried, and a lower oil tank provided below the upper oil tank so as to be continuous with the upper oil tank, and configured to sink and collect moisture and fried scraps released from the food material into the upper oil tank, the heater including a side heater partitioning an inside of the upper oil tank into one or a plurality of cooking areas, and surrounding the one or the plurality of cooking areas, and a lower heater provided at a bottom of the one or the plurality of cooking areas.
