A switch-cycle current limiting protection circuit for output short circuit includes diodes D6, D5, D2, D9, D4, and D3, drive windings T2-2 and T2-3, resistors R4 and R7, transistors Q2 and Q1. This circuit prevents transistors Q2 and Q1 in the half-bridge circuit of the electronic transformer from being deeply saturated and burning out due to excessive current, thus achieving switch-cycle current limiting protection. Therefore, an electronic transformer with an output short circuit switch-cycle current limiting protection circuit can also achieve switch-cycle current limiting protection.

This utility model discloses an atomizer and an electronic cigarette using the same. The atomizer includes an oil storage body and an atomizing body. The oil storage body has an oil storage chamber and a receiving chamber that are isolated from each other. The atomizing body is located in the receiving chamber. An oil guide hole is provided on the corresponding chamber wall of the receiving chamber for guiding the e-liquid from the oil storage chamber into the receiving chamber. The atomizing body has an atomizing channel, within which are arranged an electric heating element, an oil-absorbing element wrapped around the electric heating element, and an oil guide element made of a material with good adsorption and permeability wrapped around the oil-absorbing element. An oil inlet hole corresponding to the oil guide element is provided on the atomizing body. This utility model, by adopting the above technical solution, solves the problem that existing electronic cigarette atomizers have multiple layers of oil-absorbing elements wrapped around the electric heating element. This not only increases the cost of several layers of oil-absorbing elements but also slows down the oil absorption speed. Furthermore, impurities mixed in the e-liquid can deposit on the outer layer of the oil-absorbing element, preventing e-liquid from entering the inner layer and causing the oil-absorbing element to burn.

This invention discloses a deposition apparatus based on diamond semiconductor wafers, relating to the field of diamond deposition technology. In this invention, a waveguide channel is provided within the waveguide assembly. A cavity wall assembly one is mounted on top of the cavity bottom assembly and includes a cutoff plate and a gas supply pipe assembly. A cavity wall assembly two is sealed to cavity wall assembly one to form an anti-wave cavity and a resonant cavity. When cavity wall assembly two is sealed to cavity wall assembly one, the cutoff plate is located within the resonant cavity. The deposition substrate is located within the anti-wave cavity and directly below the cutoff plate. Microwaves generate a resonant wave between the cutoff plate and the deposition substrate. This resonant wave is used to resonate with the mixed gas to generate a plasma ball. This invention uses a hydraulic rod to ensure the movement control of the lower cavity wall assembly two, allowing cavity wall assembly two to achieve tight docking or separation from cavity wall assembly one. This enables rapid loading and unloading of the deposition substrate after diamond deposition, preventing burns caused by the internal temperature of the deposition cavity and facilitating efficient diamond removal.
