5results about How to "Avoid finding" patented technology

The invention relates to the technical field of household appliances, particularly provides a household appliance and a control method thereof, and aims to solve the problem of inconvenient operation caused by the fact that a user cannot accurately find the position of a power key in the prior art. In order to achieve the purpose, the control method comprises the steps that when the household electrical appliance is in a power-off state, whether a human body enters a preset range of the household electrical appliance or not is judged; when the human body enters the preset range, acquiring the height of the human body; obtaining the staying duration of the human body in a preset range; and selectively waking up the power key based on the height and the staying duration. When the user tends to use the household electrical appliance, the power key is awakened and lightened in time, so that the user can conveniently find the power key and turn on the household electrical appliance for use, and the user experience can be effectively improved.

The utility model discloses an intelligent key with a waterproof soft key structure, which comprises an intelligent key shell and a top shell, the top shell is arranged at the top end of the intelligent key shell, a first key is arranged at the front end of the intelligent key shell, a second key is arranged at the bottom end of the first key, and a third key is arranged at the bottom end of the second key. A protection structure is arranged outside the intelligent key shell and comprises a protection shell, a fixing groove, a first reserved groove and a fixing shaft, and the first reserved groove is formed in one side of the bottom end of the front end of the intelligent key shell. According to the intelligent key with the waterproof soft key structure, by arranging the protective shell and other parts, when the intelligent key is not used, the protective shell can be driven to rotate due to the fact that the fixing groove is connected to the outer portion of the fixing shaft in a sleeving mode and can rotate, and therefore the protective shell can be overturned upwards to cover the shell of the intelligent key, and the intelligent key is more suitable for use; the problem that no anti-abrasion and anti-falling protection exists outside is solved.

The utility model discloses a full-automatic yarn twisting machine, which relates to the technical field of full-automatic yarn twisting equipment, and comprises a box body, a mounting plate is fixedly mounted in the box body, a switching mechanism is arranged in the box body and is used for realizing the replacement of twisting degrees of various yarns, and the switching mechanism comprises a rotating unit which is arranged at the top of the mounting plate and is used for driving the mounting plate to rotate; comprising a rotating shaft rotationally mounted at the top of a box body, and an intermittent turntable is fixedly mounted on the outer ring of the rotating shaft; the kinetic energy unit and the driving motor operate to drive the linkage rotating disc to rotate, the linkage rotating disc drives the positioning arc-shaped disc and the sliding column to synchronously rotate, the sliding column slides into the rectangular groove to enable the rectangular groove to rotate, the rectangular groove drives the rotating mounting disc and the mounting column to rotate, at the moment, the sliding column slides out of the rectangular groove, and the arc-shaped end of the positioning arc-shaped disc rotationally slides into the arc-shaped groove. And the rotation of the intermittent turntable is positioned, so that the conversion among various yarns is realized, and the working efficiency is improved.

The utility model discloses a marine methanol engine fuel leakage monitoring devices, including connecting channel block, two -way electromagnetic valve and methanol concentration sensor, and the methanol double -walled common rail pipe is fixed between the connection of a plurality of connecting channel blocks respectively. Two -way electromagnetic valve body embeds and fixes in the big end sink hole of connecting channel block rear side ladder sink hole, and the valve core of two -way electromagnetic valve embeds the small end sink hole in the ladder sink hole, and the small end sink hole is perpendicular with the intercommunication hole vertical intersection. The outside of connecting channel block front end center observation window sink hole is equipped with installed transparent observation window, and the one end of detection channel hole is communicated with observation window sink hole respectively, and the other end is perpendicular with the corresponding several outer tube lead -through hole vertical intersection respectively. Methanol concentration sensor lower end is fixed in the upper end of sensor screw hole. The utility model discloses can find the leakage point of methanol double -walled common rail pipe in time fast accurately, and the user is convenient for timely maintenance, thereby has improved the security in the use process of marine methanol engine significantly.
