as shown in fig. 1-10, the paper towel dispenser of the present embodiment comprises:

The paper towel dispenser comprises a shell 1, a paper towel storage cavity 11 and a paper towel dispenser, wherein the shell is provided with the storage cavity 11 for containing paper towels 100;

A dispensing mechanism 2 mounted on the housing 1 and located at one side of the storage cavity 11 and used for outputting the paper towel in the housing 1 to the outside of the housing 1;

And a humidifying mechanism 3 configured with a nozzle 31 for spraying water outwards, wherein the nozzle 31 is positioned at the side of the paper outlet of the dispensing mechanism 2 and is used for humidifying the paper towel output from the dispensing mechanism 2.

specifically, the housing 1 of the tissue dispenser of the present embodiment is used for storing tissues, and the tissues stored in the housing 1 are supplied to the outside through the dispensing mechanism 3, and in case that the user needs to humidify the tissues, the nozzles 31 of the humidifying mechanism 3 spray water onto the tissues to humidify the tissues. And because nozzle 31 is located the outside of the outside play paper zone of distribution device 2, like this, can ensure that the paper handkerchief that the distribution device 2 carried keeps dry and comfortable state, avoid wet paper handkerchief to glue on distribution device 2 and break down, simultaneously, to the paper handkerchief from the output of distribution device 2, can be more quick effectual humidify through nozzle 31, simultaneously, the paper handkerchief that is humidified directly exports from shell 1 and makes the user obtain more comfortable use experience, and, the paper handkerchief is directly exported by the humidification and is more favorable to reducing the water consumption, avoid the paper handkerchief after the humidification to produce the problem that moisture scatters and disappears through the output of distribution device 3. Wherein the paper towel dispenser is provided with an electric control board 10, and the operation of the dispensing mechanism 2 and the humidifying mechanism 3 is controlled by the electric control board 10.

In order to enable smooth fixed length delivery of the paper towel 100, the dispensing mechanism 2 of the paper towel dispenser of the present embodiment includes: the conveying component 21 is used for driving the paper towels to be output to the outside of the shell 1; a cutting unit 22 for cutting the paper towel output by the conveying unit 21; and a driving mechanism 23 for providing a driving force to the conveying assembly 21 and the cutting assembly 22. Specifically, the tissues stored in the housing 1 are transported outward by the transport unit 21, and after a certain length of tissue is transported, it can be automatically cut by the cutting unit 22 for the convenience of the user.

in order to improve the convenience of the user, the user can conveniently place the tissues in the conveying assembly 21 for conveying, and a cover plate 12 for opening and closing the storage cavity 11 is arranged on the housing 1; the conveying assembly 21 comprises a conveying main shaft 211 and a conveying pressing shaft 212, the conveying main shaft 211 is rotatably mounted on the housing 1 and located outside the storage cavity 11, the conveying main shaft 211 is in driving connection with the driving mechanism 23, and the conveying pressing shaft 212 is rotatably mounted on the cover plate 12; when the cover 12 closes the storage cavity 11, the transfer pressing shaft 212 presses against the transfer main shaft 211. Specifically, the driving mechanism 23 provides power to the transmission main shaft 211 to make it actively rotate, when in actual use, a user opens the cover plate 12 to put the roll paper wound with the paper towel into the storage cavity 11, draws out one end of the paper towel and bypasses the transmission main shaft 211, then closes the cover plate 12, at this time, the transmission pressing shaft 212 presses the paper towel onto the transmission main shaft 211, after the driving mechanism 23 drives the transmission main shaft 211 to rotate, the transmission pressing shaft 212 and the transmission main shaft 211 clamp the paper towel to output the paper towel outwards, wherein, two side parts of the cover plate 12 are provided with strip-shaped holes (not marked), the end part of the transmission pressing shaft 212 is inserted into the corresponding strip-shaped holes, a pressing spring (not shown) is further arranged between the end part of the transmission pressing shaft 212 and the cover plate, after the transmission pressing shaft 212 presses the transmission main shaft 211, the pressing spring is compressed at the same time, the pressing spring provides spring force to the transmission pressing shaft 212, so that the conveying pressing shaft 212 is tightly pressed against the conveying main shaft 211, thereby ensuring smooth and smooth output of the paper towel, wherein the pressing spring can be in a torsion spring or compression spring structure.
