The embodiment of the invention relates to the technical field of wearable devices, and discloses a voice wake-up method and system based on a bone conduction earphone, and the bone conduction earphone. The method comprises the following steps: when the bone conduction earphone starts a voice wake-up function, detecting whether the bone conduction earphone receives a voice command used for waking up the bone conduction earphone; if the bone conduction earphone receives the voice command, waking up the bone conduction earphone; identifying whether the voice command is matched with any preset voice command used for waking up a wearable device connected with the bone conduction earphone; and if so, sending the voice command to the wearable device through the Bluetooth of the bone conduction earphone so as to wake up the wearable device. By implementation of the embodiment of the invention, the voice wake-up function with low power consumption can be realized in the wearable device, and the cruising ability of the battery of the wearable device is improved.

The invention discloses a thermal-insulation fireproof steel structure. A steel structure body (1) is a square steel tube or a round steel tube, multiple hollow tubes (2) with two closed ends are arranged inside the steel structure body (1), and the upper portion of an inner cavity of the steel structure body (1) is connected with an exhaust pipe (3); the lower end of the inner cavity of the steel structure body (1) is connected with a water inlet pipe (4), the upper end of the same side is connected with a water outlet tube (5), a water source sequentially passes through a water pump (6) and a one-way valve (7) to enter the inner cavity of the steel structure body, a starting switch of the water pump (6) is connected with an electromagnetic valve (8), and the other end of the electromagnetic valve (8) is connected with a temperature sensor (9). The interior of a steel structure building can be kept at constant temperature for a long time, and meanwhile fireproofness can be achieved effectively at a low cost.

The invention provides a heat-sensitive ticket printer preventing local overheating. According to the ticket printer, a forward paper feeding direction and a reverse paper feeding direction are provided, and the positions of common heating elements in a printing head are judged according to heating records; next, under the condition of possible local overheating, the bitmap of a ticket to be printed currently is analyzed so as to determine the time sequence distribution of print points when the ticket is printed in the forward paper feeding direction and the reverse paper feeding direction; and then, the heating time intervals of the common heating elements in the forward paper feeding direction and the reverse paper feeding direction are respectively determined through matching operation, the paper feeding direction in which the heating time interval can be delayed is selected from the two paper feeding directions, and a corresponding time sequence scheme is selected.

The invention provides an electric fan. The electric fan comprises a supporting column, a lifting structure, a clamping structure and a fan head, wherein the lifting structure is movably arranged on the supporting column, the clamping structure is arranged on the lifting structure and can be matched with the supporting column in a clamping mode, and the fan head is arranged on the lifting structure. According to the electric fan, the clamping structure is arranged to clamp the supporting column, and after height adjustment of the fan head is completed, continuous work of a motor is avoided through clamping between the clamping structure and the supporting column, so that damage to the motor is avoided, and the precision and reliability of height adjustment of the fan head are guaranteed; and meanwhile, through rotation of a fan head fixing frame and a reset mechanism, a clamping groove fixing plate can clamp the supporting column according to needs, so that the reliability of height adjustment of the fan head is guaranteed.

The invention discloses a double transfer bucket garbage transferring and storing method and device for an electric sweeping vehicle. An intermittent cycle operation mode is adopted in the double transfer bucket garbage transferring and storing method. The double transfer bucket garbage transferring and storing method is characterized by comprising the steps that garbage swept into a transition drum through a rolling brush is pushed to a left transfer bucket and a right transfer bucket through a left transition push plate and a right transition push plate which are arranged in the drum respectively; the left transfer bucket and the right transfer bucket simultaneously rise to an entrance of a lateral dumping slideway, and the garbage in the transfer buckets is pushed out of the transfer buckets through left-and-right motion of electric push rods, the garbage is dumped into a standard garbage can through the lateral dumping slideway; the left transfer bucket and the right transfer bucket simultaneously fall to a left port and a right port of the transition drum. The double transfer bucket garbage transferring and storing device comprises a transition device arranged behind a rolling brush device, lifting devices arranged in the middle of the sweeping vehicle and the lateral dumping slideway arranged on the upper portion of the standard garbage can, wherein the transition device is provided with a left transition drum pushing mechanism and a right transition drum pushing mechanism which are used for pushing the garbage, and the lifting devices are provided with the left transfer bucket and the right transfer bucket which can rise and fall. The device is easy to run and operate, high in reliability and capable of replacing a high-power fan dust suction device for the sweeping vehicle and effectively reducing battery energy consumption.
