Filed: 2019-06-22
Abstract: The present invention relates to a vehicle stabilizer. According to the present invention, wheels are allowed to be maximally independently moved when a vehicle travels straight at constant speed such that a flexible response is performed when the wheels are impacted by a road obstacle. In addition, inclination of the vehicle due to a roll or a pitch is reduced or the vehicle is inclined in an opposite direction by strengthening or elongating a spring of a wheel which greatly receives centrifugal or inertial force by twisting a stabilizer bar during curving or acceleration/deceleration. The stabilizer according to the present invention has a feature for adjusting elasticity of the stabilizer if necessary. In addition, a stabilizer fixing device according to the present invention uses the spring and thus, does not fundamentally generate noise, lubricating and slipping problems. The stabilizer can be used between left and right wheels in preparation for curving of the vehicle, and can be used between front and rear wheels in preparation for acceleration/deceleration. Furthermore, the stabilizer can contribute to improvement of riding comfort of the vehicle.

Title: Over-temperature protection structure and hair drying apparatus
Inventor: CHEN XU
IPC: H05B1/02
Filed: 2019-08-14
Abstract: The present invention belongs to the technical field of a handheld device and particularly relates to an overheating protection structure and a hair drying device. The overheating protection structure includes a main body, a heater, and a first overheating protection member. The heater includes an inner layer and a heating element. The inner layer is placed inside the heating element and configured to support the heating element. The first overheating protection member is installed inside the heating element. Therefore, when the temperature of the heater is relatively high, the heater and the power will be turned off, and the heater will stop working to prevent the damage to the heater and surrounding elements due to overheating, thereby protecting the whole hair drying device. Compared to an overheating protection member installed outside the heater, the first overheating protection member of the hair drying device is installed inside the heater. Therefore the temperature standard, in which the first overheating protection member cuts off the power, becomes the temperature inside the heater to more intuitively reflect the temperature of the heater, thereby improving the safety performance and the use performance of the hair drying device.
