Abstract: A temperature control system for appliances, such as an electric grill, air fryer, vacuum blender, convection oven, induction cooker (e.g., wok), coffeemaker, etc. The control system comprises digital circuitry for controlling temperature of the appliance, and includes a first safety component in the circuitry for stopping the heating function at a threshold parameter, such as a maximum temperature, and a second safety component in the circuitry for stopping the heating function at a second threshold temperature if the first safety component fails at the first threshold temperature. The first and second safety components, preferably switches or fuses, are connected in series to establish a redundant safety mechanism.

Abstract: A liftable and adjustable shower device, that includes: an outer tube, an inner tube, an upper fixing seat, and a liftable tube. The outer tube is disposed in the shower device; and the inner tube is disposed in the outer tube. The upper fixing seat is disposed around an upper end of the outer tube. The liftable tube is sleeved around the inner tube, the liftable tube is insertable from an upper end of the upper fixing seat, to sleeve around outside the outer tube.

Abstract: An air purifying system having a series of specific filters stacked to facilitate removal of particles from the air. Removable filters include a pre-filter, a HEPA electrostatic filter, an activated carbon filter and a cold catalyst filter. Additional filters or alternate filters may be used, so long as there is no negative impact on the system efficiency and effectiveness.

Abstract: A cooking control system having a temperature probe and a cooking appliance is described for permitting temperature target cooking of foods. The probe includes a metallic insertable portion with a sheathed tip and a temperature sensor positioned therein, a flexible heat-resistant wire coupled to the temperature sensor, and a jack coupled to the flexible, heat-resistant wire opposite the metallic insertable portion. The cooking appliance includes a heating unit, an housing, a temperature reader, and an alpha-numerical display. In use, the temperature sensor produces a signal in response to a temperature sensed at the sheathed tip and the heat-resistant wire and jack transmit the signal produced by the temperature sensor to the port of the cooking appliance. The temperature reader within the housing is coupled to the port and configured to accept and accurately convert the signal produced by the temperature sensor to a number representing the temperature sensed by the sensor and display the number for the user.

Abstract: A direct action solenoid valve includes: a valve body, on the valve body is disposed a water inlet port and two water outlet ports, the two water outlet ports are a first water outlet port and a second water outlet port respectively; a first water passage channel, formed between the water inlet port and the first water outlet port, and a second water passage channel, formed between the water inlet port and the second water outlet port; a chamber, formed between the first water passage channel and the second water passage channel; a control piece, disposed in the chamber, to control the first water outlet port to open; a solenoid valve head, disposed in the valve body; and a hydroelectric generator, disposed in the valve body to supply power to the solenoid valve head.

Abstract: A push button switching spool includes a switching body. The switching body includes a housing, a water inlet and a water outlet, wherein the housing comprises an upper casing and a lower casing with a gap for passing water. A mandrel is disposed in the housing, and the mandrel axially moved within the housing. The mandrel comprises a plurality of grooves with sealing rings. And, a left protrusion and a right protrusion are formed on each groove, wherein a diameter of the left protrusion is the same as a diameter of the right protrusion. The push button switching spool can normally switch water paths at high water pressure.

Abstract: A system and method for induction cooking using an induction cooking unit, an interface adapted to receive, store, and execute a plurality of instructions of a multistage programmable recipe using the induction cooking unit, a power supply, a controller coupled to said power supply, said interface, and said induction cooking unit.

Abstract: An electrical dispensing assembly for a shower sprinkler having a body provided with multiple first outlets includes a dispensing disk having multiple second outlets communicating with the first outlets of the body, a rotation disk rotatably mounted on top of the dispensing disk and having at least two third outlets each alternately communicating with one of the second outlets so as to change water output pattern from the body and a driving device mounted on a side of the rotation disk to drive the rotation disk for a predetermined period of time.

Abstract: A method of making an article coated with DLC, includes providing a substrate; depositing a transition layer on the substrate by means of magnetron sputter deposition (MSD); depositing a DLC layer without hydrogen (H) on the transition layer by means of filtered cathodic vacuum arc (FCVA); and doping a fluorine-doping (F-doping) layer on the DLC layer. The article has good film bonding force, high hardness, good wear resistance, good hydrophobicity and oleophobicity and high light transmittance, and the DLC layer has no H included.
