4results about How to "Improve deodorization function" patented technology

The invention relates to a preparation method of polyester yarn with a deodorization function, which comprises the following steps: putting a solvent-free bi-component deodorization finishing agent into an oil bath tank, and keeping the temperature at 40-50 DEG C to enable the viscosity to be 200-400 mPa.s; a product is prepared by a spinning process of melting a polyester raw material, metering, spinning, cooling, passing through an oil bath tank, stretching, thermocuring and winding and forming. The solvent-free bi-component deodorization finishing agent is obtained by uniformly mixing a component A and a component B at room temperature, the component A is a deodorization modifier and bio-based macromolecular polyol subjected to vacuum dehydration, and the component B is a curing agent and a catalyst; the synthesis method of the deodorizing modifier comprises the following steps: mixing 90-95 parts by mass of epoxy modified montmorillonite, 5-10 parts by mass of zinc diricinoleate and 200 parts by mass of ethanol, adjusting the pH value of the system to 3-4, and reacting at 40-50 DEG C to obtain the deodorizing modifier. According to the invention, the polyester yarn is endowed with an efficient and lasting deodorization function.

The invention discloses a sock deodorization finishing device, and relates to the technical field of articles for daily use, the sock deodorization finishing device comprises a finishing cabinet and a placing drawer, the back of the finishing cabinet is provided with a ventilation fan, the bottom surface of the inner side of the placing drawer is provided with a placing plate, and the placing plate is in a criss-cross grid shape; the placing plate comprises a plurality of air cavities which are formed in the placing plate, the cross section of each air cavity is smaller than that of the placing plate, the air cavities are communicated with one another in a criss-cross manner, and at least one air cavity is communicated to the air inlet end of the ventilation fan; according to the sock drying device, air can be evenly guided to the bottoms of socks to be blown out through a ventilation fan, a placement plate, an air cavity and blowing holes, peculiar smells emitted by the socks are effectively taken away, the socks are kept in a good ventilation environment, the problem that the socks are smelly due to peculiar smell accumulation is solved, meanwhile, the growth environment conditions of microorganisms such as bacteria and fungi are destroyed, and the sock drying effect is improved. The phenomenon that the socks are smelly due to the fact that some odorous substances are generated in the metabolism process of microorganisms is prevented.

This utility model relates to the field of odorless toilet technology, specifically to a suction and discharge device and a toilet incorporating the device. The device includes a suction and discharge connector for installation on the toilet. The connector has an air intake channel and a drainage channel. The air intake channel has an air intake port and an exhaust port at its two ends, respectively. The exhaust port is connected to a fan, and the negative pressure generated by the fan's rotation draws air from the toilet body into the air intake port. The drainage channel has a spray outlet and a water inlet at its two ends, respectively. The water inlet is connected to a water inlet pipe, and the spray outlet sprays water from the water inlet pipe onto the toilet's drain surface to flush it. This utility model combines deodorization and flushing by integrating the air intake and drainage channels at the suction and discharge connector. Furthermore, the spray outlet sprays water onto the drain surface, reducing water loss during flow and improving flushing efficiency.

The utility model provides a drainage device facilitating bladder pressure measurement, and relates to the field of medical instruments. The drainage device facilitating bladder pressure measurement comprises a drainage bag, a drainage tube and a branch tube connected with the drainage tube, the top of the drainage bag is connected with a first flow guide tube, the top of the first flow guide tube is fixedly connected with a fixing cylinder with the interior communicated, and the inner wall of the fixing cylinder is slidably connected with a sealing plug used for sealing the top end of the first flow guide tube; two fixing rods are symmetrically and fixedly connected to the side, close to the first flow guide pipe, of the sealing plug, clamping plates are jointly and fixedly connected to the ends of the fixing rods, and connecting rods extending to the outer sides of the fixing cylinders are fixedly connected to the outer sides of the clamping plates; a through groove is formed in the top of the fixing cylinder, and a second flow guide pipe extending into the first flow guide pipe is inserted into the through groove in a penetrating mode. According to the drainage apparatus convenient for measuring the bladder pressure, the drainage bag can be cleaned, so that the drainage bag can be recycled while the sanitary use of the drainage bag is ensured, the use cost is reduced, and the practicability is high.
