The application discloses an oxygen-increasing and current-creating device, and belongs to the technical field of water oxygen-increasing and current-creating equipment. The device comprises an oxygen-increasing assembly and a current-creating assembly. The oxygen-increasing assembly comprises a high-pressure water flow pushing device. The water outlet end of the high-pressure water flow pushing device is connected with a micro-nano bubble generator. The water outlet end of the micro-nano bubble generator is connected with a micro-nano bubble releaser. The micro-nano bubble generator is connected with an air pipe. The air inlet end of the air pipe is located on the water surface. A plurality of driving paddle wheels are uniformly arranged on the middle part of the driving shaft along the circumferential direction of the driving shaft, so that the high-pressure water flow passing through the micro-nano bubble releaser is sprayed to the plurality of driving paddle wheels in sequence. The structure of the micro-nano bubble generator and the micro-nano bubble releaser is adopted to realize the efficient dissolution of air and high-pressure water flow. The driving paddle wheels are driven to rotate the driven paddle wheels, centrifugal force is formed to drive the water body to rotate, the backflow effect of the backflow cover is coordinated, the surrounding water body is driven to form an overall circulation, and the water body is activated uniformly.

The invention provides a PVA (Polyvinyl Alcohol) film toilet seat cushion as well as a production method and equipment. The production method of the PVA film toilet seat cushion specifically comprises the following steps: S1, preparing a modified PVA film; s2, unwinding is carried out; s3, preheating the PVA film; s4, the PVA film is atomized; s5, covering is carried out; s6, on-line pressure detection is carried out; s7, atomization of the toilet seat cushion; and S8, rolling is conducted. And the like. After the PVA film is modified, the plasticizing and moisturizing properties of the PVA film are realized, so that the PVA film has the function of an adhesive when being coated with water and heated, good bonding strength can be obtained without additionally adding an adhesive in the process of coating paper on the PVA film, and the antibacterial and bacteriostatic effects of the product are improved; the produced PVA film toilet seat cushion product has the advantages of no chemical adhesive, excellent antibacterial and bacteriostatic performance, comfort in use (skid resistance and flexibility), capability of being quickly dissolved in water, environment friendliness and stable and reliable production quality.
