The utility model relates to the technical field of sound wave skin care equipment, in particular to mask type air coupling ultrasonic infiltration promotion equipment, which comprises a mask body and a wearing structure connected with the mask body, a visible window is arranged on the mask body corresponding to eye sockets, and a plurality of air coupling transducers are arranged on the surface, facing the wearing structure, of the mask body; the edge of the visible window is provided with a supporting body facing the wearing structure, through the supporting body arranged on the edge of the visible window, an air gap is formed between the air coupling transducer and the face of a user in the wearing process of the user, the air coupling transducer acts on the face of the user or a skin care product in a spaced mode, operation is easy and convenient, safety is higher, and the user experience is improved. The percutaneous penetration of the medicine or the skin care product can be realized without tightly attaching the equipment to the skin, the safety and the penetration effect are improved, the applicability is wide, the percutaneous penetration device can adapt to different types of skin care products, and the penetration promotion effect is improved.

This utility model discloses a constant temperature heating coaster, including a coaster body; the coaster body consists of an outer shell and a holding plate, with a protective shell installed at the bottom of the holding plate, the bottom end of the protective shell extending into the outer shell, a weighing sensor installed between the bottom end of the protective shell and the interior of the outer shell, a controller installed at the front end of the outer shell, and a voice recognition module installed on the other side of the front end of the outer shell. A heating element is installed inside the bottom end of the holding plate, and a temperature sensor is installed inside the protective shell. The temperature sensor, heating element, weighing sensor, and voice recognition module are connected to the controller via wires. This utility model uses voice control to start, stop, and adjust the heating temperature. Simultaneously, the weighing sensor stores the weight of the cup, and by comparing the weight with the water level in the cup, the controller automatically determines whether to continue heating based on the water level, avoiding heating an empty cup and preventing heating from continuing when there is no cup on the holding plate.

The utility model belongs to cable traction device technical field provides a traction equipment for cable, include: rack, traction mechanism, its setting on the rack and including opposite setting first conveyer belt and second conveyer belt on the rack, first conveyer belt and second conveyer form the traction space of traction cable movement, drive mechanism, its setting on the rack, control mechanism, traction mechanism includes the state of entering material and traction state. Compared with prior art, the utility model through setting switchable " the state of entering material " with " traction state " has realized under the partial clamping condition to complete the threading operation of big outer diameter cable. Especially under the state of entering material, allows one side conveyer belt to keep clamping (such as clamping traction rope), the other side loosens for cable to enter, thereby realizes " new mode of threading while traction ", has improved the operation convenience, threading efficiency and production continuity of equipment significantly, has laid the foundation for subsequent intelligent control.

The invention discloses an efficient and energy-saving fuel gas complete combustion method, which ensures that fuel gas is completely combusted at a high temperature of 800-1000 DEG C by accurately controlling fuel gas flow and combining secondary combustion and optical reflection technologies. Firstly, fuel gas is subjected to primary combustion through a tiny discharge port, the flame size and the fuel gas flow are controlled through an electronic igniter, and sufficient primary combustion is ensured. And then, the gas which is not completely combusted is guided to a fire gathering combustor, and flame and heat are focused to the bottom of the pot for secondary combustion by utilizing a light reflection principle. A traditional pot support is omitted, a fire gathering burner is adopted for supporting, the equipment structure is simplified, and attractiveness and stability are improved. The gas stove is suitable for household and commercial gas equipment, is widely applied to gas stoves, water heaters, warmers and the like, and has remarkable energy-saving and environment-friendly effects.

The utility model discloses a raisin careful selection and stone removal device which comprises a positioning frame, the positioning frame is used for supporting and positioning the raisin careful selection and stone removal device, a careful selection and stone removal mechanism is fixedly arranged in the positioning frame, and a careful selection adjusting mechanism is fixedly arranged on the inner wall of the careful selection and stone removal mechanism. The fine selecting and stone removing mechanism comprises a separation frame, and a stone receiving frame is arranged on one side of the separation frame in a sliding mode; the output end of the vibration motor drives the feeding guide frame to perform vibration feeding, and the stone removing induced draft fan performs blowing work, so that raisins deviate from the original track due to wind resistance and enter the inner wall of the collecting frame through separation of the separation frame; and meanwhile, light impurities guided out through air flow are filtered and collected through a filter screen, so that the raisins are carefully selected and subjected to stone removal, the problem that the outer skins of the raisins are damaged is avoided, meanwhile, the impurities in the raisins are removed, and the use convenience of the raisin carefully selecting and stone removing device is improved.
