[0006] A casing with a paper outlet at the bottom, and a cutter is provided at the paper outlet;

[0007] A paper outlet module, including a paper outlet mold shell, a paper outlet roller installed in the paper outlet mold shell, and a paper outlet power group. The paper outlet power group is used to drive the paper outlet roller to rotate. The paper outlet mold shell is detachably installed in the casing so that the paper outlet roller is located on one side of the paper outlet;

[0008] A paper pressing module, including a paper pressing mold shell, a paper pressing roller rotatably installed in the paper outlet mold shell, and an elastic mechanism acting between the paper pressing roller and the paper pressing mold shell. The paper pressing mold shell is detachably installed in the casing so that the paper pressing roller is located on the other side of the paper outlet. The elastic mechanism is used to elastically abut the paper pressing roller against the outer periphery of the paper outlet roller.

[0009] The beneficial effect of the utility model is:

[0010] During use, the paper roll is installed in the casing. After the roll paper passes through the paper pressing roller and the paper outlet roller, it extends out from the paper outlet. Under the action of the elastic mechanism, the paper pressing roller presses the roll paper tightly against the outer periphery of the paper outlet roller. When paper needs to be taken out, the paper outlet power group drives the paper outlet roller to rotate to drive the roll paper to extend out of the paper outlet according to a preset length, and then the roll paper is pulled to make the cutter cut the roll paper to realize automatic hand wiping paper. In this technology, both the paper pressing module and the paper outlet module are installed in the casing in a modular installation manner, which is convenient for production and manufacturing.

The utility model realizes an increase in driving force through the planetary gear set 240 to achieve a strong rotation of the paper outlet roller 220, so as to quickly take out the roll paper.

[0045] As Figure 7 shown, the paper pressing module 300 of this embodiment includes a paper pressing housing 310, a paper pressing roller 320, and an elastic mechanism. The paper pressing roller 320 also extends horizontally. The paper pressing roller 320 is rotatably installed in the paper pressing housing 310. The elastic mechanism acts between the paper pressing roller 320 and the paper pressing housing 310. The paper pressing housing 310 is detachably installed in the housing 100. The paper pressing roller 320 is disposed on the other side inside the paper outlet 110. The elastic mechanism is used to elastically abut the paper pressing roller 320 against the outer circumference of the paper outlet roller 220.

[0046] During use, the paper roll is installed in the housing 100. After the roll paper passes through the paper pressing roller 320 and the paper outlet roller 220, it extends out from the paper outlet 110. Under the action of the elastic mechanism, the paper pressing roller 320 presses the roll paper tightly against the outer circumference of the paper outlet roller 220.

An induction port 170 corresponding to the first induction sensor 250 is provided at the bottom of the machine shell 100. The induction port 170 is located beside the paper outlet 110. When the first induction sensor 250 senses an external hand movement, the motor 230 starts, driving the paper outlet roller 220 to rotate. At this time, the roll paper extends out according to a preset length.

[0054] When it is sensed that there is a roll of paper extending outside the paper outlet 110 and staying for a period of time, the motor 230 is started at this time and driven in reverse to roll the extended roll of paper back, so as to avoid having too long a roll of paper outside the paper outlet 110 and prevent the roll of paper from staying for too long and affecting the next use.

[0055] In some other solutions, the first induction sensor 250 can control the start and stop of the motor 230 according to the induction time. It can be understood that when the first induction sensor 250 continuously senses the external hand movement, the motor 230 remains in the starting state, and at this time, paper is continuously discharged. When the first induction sensor 250 does not sense the external hand movement, the motor 230 stops operating.

[0056] In this embodiment, a supporting wheel 122 is provided at the bottom of the paper roll placement position 120. The supporting wheel 122 of this embodiment is installed on the paper outlet mold shell 210.

The cutter 130 is detachably installed on the paper outlet mold shell 210 through the tool holder 131, improving the modular effect.

[0059] Moreover, the cutter 130 of this embodiment is arranged on the front side inside the paper outlet 110. When tearing off the roll of paper, only need to pull the roll of paper forward. At this time, the roll of paper contacts the cutter 130, and continue to pull forward to cut off the roll of paper, which is convenient for the paper cutting operation. The cutter 130 adopts a serrated knife.

[0060] A plurality of friction sleeves 221 are sleeved on the outer periphery of the paper outlet roller 220 of this embodiment. The paper outlet roller 220 contacts the roll of paper through the plurality of friction sleeves 221. The friction sleeves 221 can improve the contact friction force between the paper outlet roller 220 and the roll of paper, making the paper discharge more smooth and avoiding the phenomenon of slipping.

[0061] As Figure 2 and Figure 3 shown, the paper outlet 110 is provided with a paper outlet guiding cover 111, and the roll of paper extends along the paper outlet guiding cover 111.
