This utility model belongs to the field of toilet cleaning technology, specifically a slow-release structure for toilet water cleaner, including a placement cylinder; a cap is detachably installed at the end of the placement cylinder via threads; a spring is fixedly connected to the side wall of the cap; a rubber block is fixedly connected to the other end of the spring; a release hole is fixedly connected to the middle of the rubber block; a first through hole is opened in the middle of the cap; an installation block is provided on the outside of the placement cylinder; a pair of circular cavities are opened in the middle of the installation block; a suction cup is fixedly connected to the end of the circular cavity; a pull rod is fixedly connected to one side of the suction cup located in the circular cavity; the pull rod is slidably connected to the middle of the installation block; with the above structure, after the block cleaner is placed into the toilet tank, the water liquid can come into contact with a small amount of block cleaner surface, thereby reducing the release rate of the block cleaner, and even when the block cleaner shrinks due to gradual release, the block cleaner can still come into contact with a small amount of water liquid and be slowly released.

This invention discloses a method for releasing cotton aphid parasitic wasps. By releasing the wasps at three different stages of cotton growth—from the three-leaf stage to the budding stage, the boll-forming stage, and the cotton boll-opening stage—and using a specific wasp-to-aphid ratio, the control effect on cotton aphids is stable and does not rebound. Simultaneously, it reduces pesticide use and residues, improves cotton quality and market competitiveness, protects farmland biodiversity and the ecological environment, and reduces the frequency of pesticide exposure for cotton farmers, thus mitigating the impact of pesticides on human health. The technical solution provided in this application is conducive to achieving green and sustainable development of the cotton industry.

This application relates to an automated carrying system for a chemical sample transfer device, belonging to the field of chemical production equipment. It includes a transfer cylinder and a transfer system. The transfer system includes a transfer frame and a transfer rope. The transfer rope circulates on the transfer frame, with the production area and testing area located at opposite ends along its direction of travel. The transfer cylinder is suspended from the transfer rope, with openings at both its upper and lower ends. A material discharge component is provided on the transfer cylinder to control the opening and closing of its lower opening. A sealing cap is movably connected to the transfer cylinder, used to close the upper opening. An automatic cap-opening mechanism is provided at the production area to control the movement of the sealing cap relative to the transfer cylinder to open its upper opening. In this application, the transfer cylinder can automatically open its upper opening at the production area, allowing the operator to place samples into it. During transport, both the upper and lower openings of the transfer cylinder remain closed, and its internal space is almost unaffected by external environmental factors.
