The utility model relates to female sanitary product technical field discloses a sanitary tampon of instantaneous suction and lock of cotton core, including cotton core, the wrapping layer of wrapping in cotton core outside, the pull line of connecting in cotton core one end and setting in the insertion head of cotton core other end, the cotton core has three -dimensional intercommunication network structure, the cotton core includes instantaneous suction layer, flow guide layer, liquid storage lock layer and protection layer gradually from inside to outside, the porosity of instantaneous suction layer, flow guide layer, liquid storage lock layer gradually reduces. The utility model discloses through setting the cotton core of multilayer structure, and the porosity of each layer gradually reduces from inside to outside, instantaneous suction layer can rapidly absorb menstrual blood, flow guide layer guides menstrual blood to the penetration of instantaneous suction layer and prevents reverse penetration, liquid storage lock layer stores a large amount of menstrual blood and locks and prevents side leakage, and protection layer prevents the exosmosis of menstrual blood from the outside of cotton core, and the overall improvement of sanitary tampon's absorption speed, absorption capacity and side leakage prevention performance.

The utility model relates to a kind of flat mop cleaning tools, including cleaning bucket and mop, mop includes mop head, mop head is equipped with wiping article;Cleaning bucket has the clean water area, washing area and sewage area independent of each other, the outlet end of water supply channel and the bottom between washing area have a height distance, cleaning bucket is equipped with for the first water squeezing component and second water squeezing component for squeezing water to wiping article on mop head, first water squeezing component corresponds with washing area, and it is located above water supply channel, second water squeezing component is located outside washing area, and wiping article is squeezed to the mop head moving up and down, it further includes first drainage channel for the water that wiping article is squeezed down by first water squeezing component is transferred to sewage area and second drainage channel for the water that wiping article is squeezed down by second water squeezing component is transferred to sewage area. Advantage lies in: can ensure that mop is clean water each time, avoid pollution.

The utility model relates to a dehumidification device and electrical equipment, and belongs to the technical field of electrical equipment, the dehumidification device is applied to the electrical equipment, the dehumidification device comprises a radiator, the radiator is provided with a first flow channel and a second flow channel, and the first flow channel is used for being communicated with the interior of a box body of the electrical equipment; the second flow channel is provided with a first port and a second port, the first port is communicated with the first flow channel, the second port is used for being communicated with the external environment of the box body, and the second flow channel is configured to enable a medium to circulate from the first port to the second port; according to the invention, dehumidification is realized through cooperation of airflow circulation and condensation of wet air by the radiator, and the second flow channel is used for discharging condensed water and passively preventing reverse osmosis of external high-humidity air, so that the safety and the service life of electrical equipment are guaranteed; the first flow channel and the second flow channel are integrated on the radiator, so that the occupied space of an additional pipeline or an independent flow channel structure is reduced, the whole structure of the dehumidification device is compact, and the occupied space is reduced.
