The invention discloses a urine sampler for nephrology urine test, relates to the technical field of nephrology urine test sampling, comprising a sampling cup, a sampling tube horizontally arranged on one side of the sampling cup, and a circular tube screwed to the liquid inlet end of the sampling tube A cylinder connector, the air in the sampling tube is drawn out, and the cylinder connector is blocked at the liquid inlet end of the sampling tube, so that the inside of the sampling tube is in a state of negative pressure and vacuum. The beneficial effects of the present invention are: when the urine sample in the sampling cup is introduced into the sampling tube, there is no need to tilt the sampling cup, and only the sampling tube and the cylindrical connecting piece on it need to be rotated until the connecting tube in the piercing piece of the sealing cap is pierced. When the sealing cap in the cylindrical connecting piece is worn, and the liquid outlet hole on the connecting pipe is located in the sampling pipe, the urine sample in the sampling cup will be automatically sucked into the sampling pipe.

The invention discloses a device for removing excrement at the bottom of a fish tank, comprising a fish tank, a partition net is laid in the fish tank, a device plate is fixedly connected between the partition net and the inner bottom of the fish tank, and an oxygen pump is placed on the upper end of the partition net Air stone, the device plate is provided with a device chamber, the inner bottom of the device chamber is rotatably connected with a rotating shaft, the lower end of the rotating shaft is fixedly connected with a cam, and the upper end of the rotating shaft penetrates through the partition net and the oxygen pump air stone and is fixed An impeller is connected, and the impeller is located directly above the gas stone of the oxygen pump. A cavity is provided on one side of the device cavity, and the cavity is divided into a first cavity and a second cavity by a piston. The piston The side wall of the side wall is fixedly connected with a resisting rod extending into the device cavity, and the end side wall of the resisting rod is fixedly connected with a limiting plate. The invention has a reasonable structure and can cleverly use the power of the oxygen pump as a driving source to automatically realize the cleaning of pollutants at the bottom of the fish tank.

The invention relates to a splash-proof micro-nano bubble toilet accessory device. The water inlet pipeline is connected to the flush valve through the micro-nano bubble generator, and the flush valve is connected to the toilet bowl through the flush pipeline; a water inlet electromagnetic valve is arranged on the water inlet pipeline , the control part is respectively connected with the solenoid valve and the sensor signal; the sensor receives the signal generated when the user approaches, and feeds back to the control part, and the control part controls the opening and closing of the water inlet solenoid valve. The micro-nano bubble water produced by the present invention directly enters the toilet bowl without passing through the water tank, thereby ensuring the maximum bubble concentration of the micro-nano bubble water entering the bowl; the micro-nano bubble water is prepared immediately for immediate use, preventing it from being used before the next use It disappears completely; a layer of ultra-dense foam layer floating above the water surface is formed in the toilet, which plays the role of anti-splash and odor isolation, and at the same time, it can form a layer of dense nano-bubble interface water on the inner wall of the bowl before and after each use film, thereby improving the anti-fouling ability of the inner wall.

The present invention relates to the technical field of hair removal equipment for cleaning peaches, in particular to a reciprocating hair removal device for cleaning peaches; the electric push rod stretches and moves with the No. 1 rack, so that the No. 1 gear and the No. 1 rotating shaft reciprocate and rotate On the one hand, through gear transmission, the No. 2 rotating shaft and the No. 1 take-up wheel are reciprocated to rotate, and the No. 1 pull rope is released. The No. 1 slider is pulled by the No. 1 take-up wheel and the recovery of the No. 1 spring. Force, so as to achieve reciprocating movement on the No. 1 slide rail, and carry the scrubbing assembly through the No. 1 support rod to perform brushing and hair removal actions; on the other hand, the No. 1 rotating shaft rotates by itself, and the No. Cooperate with the brushing component to expand and ensure the effective area of ​​brushing and hair removal.

The invention provides an automatic air-breathing prop structure applied to a small waterplane area catamaran, and the atmosphere at the air inlet is a standard atmospheric pressure. The air inlet duct connects the air inlet with the air outlet, and the air outlet is located in the volume collapse area behind the sudden shrinkage section. When the hull is in operation, a low-pressure area will be formed at the air outlet, and the outside atmosphere will be sucked under the liquid surface and discharged from the air outlet, so as to realize the automatic suction of the pillar. The gas is discharged from the diversion surface backwards, evenly and quickly diverted to both sides of the pillar, and mixed with the incoming flow to form a gas-water mixture, covering the surface of the rear underwater part of the pillar. The invention solves the problems that the structure of the artificial ventilation device is complicated, and the power required for ventilation is relatively large, and a flow regulating device is needed to assist the ventilation, etc., the ventilation structure is simplified, and the energy saving of the ship is realized.
