This utility model discloses a novel double-buffered hinge, comprising a hinge cup, a hinge arm, a first buffer assembly disposed within the hinge arm, and a second buffer assembly disposed on the hinge cup. A rocker arm assembly is provided between the hinge cup and the hinge arm to achieve hinged opening and closing. The rocker arm assembly includes an outer rocker arm and an inner rocker arm. The first buffer assembly includes a first damper and a first drive block, the first drive block being convexly connected to the inner rocker arm. The second buffer assembly includes a second damper and a second drive block, the second drive block being convexly connected to the outer rocker arm. When the hinge cup is opened or closed, the outer and inner rocker arms can be oscillated synchronously. The inner rocker arm can drive the first drive block to drive the first damper to achieve buffering, and the outer rocker arm can drive the second drive block to drive the second damper to achieve buffering. Therefore, the hinge of this utility model has a double-buffered function, and its safety, protection, quietness, and durability are all good, making it of great market value.

An aerated concrete blank cutting line cleaning tool comprises a cleaning mechanism, the cleaning mechanism is provided with a supporting shaft rotationally arranged in a first inner cavity and permeable cleaning cotton located on the supporting shaft, and the supporting shaft is provided with a through hole assembly for inputting water into the cleaning cotton; the wax dipping mechanism is provided with a heat conducting plate which hermetically slides to divide the second inner cavity into an upper part and a lower part, and a suspension block of which the peripheral side is matched with the inner wall of the upper part of the second inner cavity and the density is smaller than that of the wax liquid; an injection hole connected with a water pressure source is formed in the upper part of the second inner cavity and is sealed through a suspension block; the suspension block is provided with a hole assembly connected with the lower portion of the second inner cavity, and when the suspension block descends by a certain height, one end of the hole assembly is connected with the injection hole. The device is simple and compact in structure, different cleaning modes of disintegrating slag on a cutting line are achieved, excessive water consumption and large noise are avoided, the height of the liquid level of wax liquid is adjusted under the conditions that non-electric equipment is adopted and the detection precision is not affected, and the device is more convenient to use.

The application provides a heat dissipation assembly and a wearable device, wherein the heat dissipation assembly comprises: a main shell configured in a flat shape, the main shell being provided with an air flow channel penetrating along the length direction thereof, an inner wall of the air flow channel being provided with a blowing port for blowing air towards an air outlet end of the air flow channel, and the air flow blown by the blowing port being used for sucking air from an air inlet end of the air flow channel towards the air outlet end of the air flow channel; a heat dissipation fan arranged on one side of the main shell in the width direction thereof, an air outlet end of the heat dissipation fan being communicated with the blowing port to convey air to the blowing port; and a heat dissipation piece arranged at the air outlet end of the air flow channel.

This utility model provides an elevator air conditioner, relating to the field of air conditioning technology. The elevator air conditioner includes: a housing with a return air vent; a partition for dividing the internal space of the housing into a first cavity and a second cavity; an evaporator disposed in the first cavity and near the return air vent; a condenser disposed in the second cavity; an axial fan disposed in the second cavity; a water tray defining a water trough located below the evaporator and condenser; a water level detection device for detecting the water level in the water trough; a water pump assembly for drawing condensate from the water trough to the condenser for evaporation; and a water agitator installed on the outer edge of the axial fan, with the bottom of the water agitator not lower than the preset high water level of the water trough. The water agitator of the axial fan serves as a backup and auxiliary means. At a preset low water level, only the water pump draws water; if the water pump is clogged, the water agitator can be used to evaporate the condensate. At a preset high water level, the water pump and water agitator work together to improve the condensate evaporation efficiency.
