The present invention relates to an e-cigarette with a plurality of heating components. The e-cigarette with a plurality of heating components is designed in the present invention, where the plurality of heating components are disposed in the atomization core, so that the e-cigarette produces more aerosol and meets user requirements; in addition, a plurality of liquid inlet holes are disposed in the atomization core, so that the e-liquid comes into contact fully with the heating components. This prevents the heating components from scorching due to insufficient e-liquid.

An apparatus for heating plastic preforms with a transport device which includes holding devices for holding the plastic preforms and wherein the transport path has at least one heating portion inside which the plastic preforms are heated, and with a heating device arranged stationary at least in portions along the transport path and which heats the plastic preforms transported by the transport device during their transport through the heating portion, wherein the heating device has at least one in particular stationary applicator device which is configured for bombarding the plastic preforms with microwaves to heat them. In the heating portion, the transport device is arranged relative to the applicator device such that at least parts of the holding devices are arranged outside the applicator device, wherein the applicator device is configured to receive several plastic preforms simultaneously for at least some of the time.

A portable food and beverage heating device including an elongated heating element designed to be immersed in a substance and to radiate heat to increase the temperature of the substance. The device further including a removable cap designed to act as an intermediary between a power supply and the elongated heating element, such that in one embodiment the heating element can only receive power from the power supply when the removable cap is secured to a second end of a housing. Additionally, the device includes several safety features like a non-conductive heat-resistant tip, a burn guard, a non-conductive fastener, and optional foldability or removability of the heating element all of which are designed to safeguard against personal injury to a user, or damage to a container holding the substance being heated.

A glass-tube heater includes a glass tube, a cap, and a temperature display unit. The glass tube is provided therein with an off-water protection sensor or a tipping switch, a control circuit board, one of a TRIAC and a relay, and a heating element. The control circuit board includes a control unit (which is an MCU or a comparator). All the components that are disposed in the glass tube are electrically connected to form a control circuit. Devices for temperature control, detection, and heating are all disposed inside the glass tube. The off-water protection sensor is operable to detect if being removed out of water for controlling the heating element to carry out heating or not, thereby ensuring quick termination of heating upon removal out of water. The tipping switch is operable to control the heating element from heating in case of excessive tipping of the heater.

An off-water shutdown protection mechanical heater includes a tube and a cap mounted to an end of the tube. The tube includes therein an off-water protection transducer, one of a relay and a TRIAC, a circuit board including a bimetal plate, and a heating element. When he off-water protection transducer detects a situation of being immersed in water, the one of the relay and the TRIAC turns on to conduct electricity and the bimetal plate detects a temperature of water and undergoes deformation by the temperature to control the heating element to generate heat or not; and when the off-water protection transducer detects a situation of being removed out of water, the one of the relay and the TRIAC turns off to cut off electricity, making the heating element not generating heat. The off-water protection transducer ensures that electricity is quickly cut off upon removal out of water.

An off-water protection heater with controller includes a controller, a tube, and a cap mounted to an end of the tube. The controller includes a control circuit and one of a relay and a TRIAC. The control circuit includes a control unit (an MCU or a comparator). The tube is provided, in an interior thereof, with an off-water protection transducer and a heating element. The off-water protection transducer is electrically connected to the control unit or is electrically connected, together with the control unit, to the one of relay and TRIAC. By using the off-water protection transducer to detect a situation of being removed out of water or not, the heating element is controlled to generate heat or not in order to ensure electricity being quickly cut off upon removal out of water thereby saving energy and preventing excessively high temperature and unloaded heating as being removed out of water.

A heating apparatus according to the present disclosure maintains the temperature of water in a trough. The heating apparatus comprises a body configured to be submerged in the trough, the body having a pump and a heating element affixed in the body, the pump configured to draw water into an intake port at a first end of the body past the heating element to heat the water and return the water through an outlet port at a second end of the body; a sensor monitoring the temperature of the water in the trough; and a control module. The control module is configured to activate either the pump or the heating element when the temperature of the water is less than a predetermined low temperature. The control module is configured to deactivate the pump or the heating element when the temperature of the water is greater than a predetermined high temperature.
