[0036] like Figure 1-11 As shown, a wet wipes machine according to an embodiment of the first aspect of the present invention includes a shell 100 and a paper feeding module. The shell 100 is provided with a storage cavity 110 for placing paper towels and a first paper outlet 120. The wall of the storage cavity 110 is provided with a second paper outlet 130. The paper feeding module is arranged in the shell 100 and the paper feeding module is located between the first paper outlet 120 and the second paper outlet 130. The paper feeding module can transport the paper towels in the storage cavity 110 from the second paper outlet 130 to the first paper outlet 120. The paper feeding module includes at least one first roller assembly 200. The first roller assembly 200 is rotatably arranged in the shell 100. The outer wall of the first roller assembly 200 can contact the paper towel. A first liquid storage cavity 230 is provided in the first roller assembly 200. A plurality of seepage ports 240 are arranged on the outer wall of the first roller assembly 200 along the rotation circumference of the first roller assembly. The seepage ports 240 are connected to the first liquid storage cavity 230.

[0037] Among them, the shell 100 is provided with an installation port connected to the storage cavity 110, so that the user can load the roll of paper into the installation port. Specifically, the shell 100 can also be provided with a pillar in the storage cavity 110, and the roll of paper can be installed on the pillar. During the process of the roll of paper outputting paper towels, the roll of paper can rotate on the pillar.

[0038] On the transmission path of the paper towels, the shell 100 can define a transmission channel by setting up multiple guide plates. The paper feeding module can be partially located in the transmission channel and in contact with the paper towels, so that the paper towels can be transported in an orderly manner in the transmission channel.

[0039] In some embodiments of the present invention, a cutting mechanism may be provided in the shell 100. After the roll of paper has output a specific length, it may be switched by the cutting mechanism, which is convenient to use and reduces waste. Alternatively, a roll of paper with a breakpoint may be used, and the user applies force on the paper towel to cause the roll of paper to tear at the breakpoint.

[0040] In the wet wipe machine of the present invention, the roll of paper can be placed in the storage chamber 110, and one end of the roll of paper can be moved out from the second paper outlet 130 to the paper feeding module. The paper feeding module can transport one end of the roll of paper toward the first paper outlet 120. The outer wall of the first roller assembly 200 can contact the paper towel. During the transportation of one end of the roll of paper, the first roller assembly 200 will also rotate. The diameter of the seepage port 240 is generally small. Under the action of water tension, the liquid in the first liquid storage chamber 230 can seep out from the seepage port 240. A plurality of seepage ports 240 are arranged in the rotating circumference of the first roller assembly, which can make the water fall evenly on the surface of the paper towel during the transportation of one end of the roll of paper, thereby forming the roll of paper into a wet paper towel and outputting it from the first paper outlet 120 for user use. It is convenient and quick to use.

[0041] It should be noted that the first roller assembly 200 in the above paper feeding module or the second roller assembly 300, the third roller assembly 400 and the fourth roller assembly 500 proposed below can all be used as active rollers or driven rollers. The active roller contacts the surface of the paper towel and rotates on its own to drive the paper towel forward. The driven roller contacts the surface of the paper towel during the transmission process, so that the paper towel can drive the driven roller to rotate.

[0042] In some embodiments of the present invention, Figure 3 、 4 As shown in Figure 7, the paper feeding module also includes a second roller assembly 300, which is rotatably arranged on the shell 100. The outer wall of the second roller assembly 300 can contact the paper towel. A first heating element 310 is arranged in the second roller assembly 300, and the first heating element 310 can heat the paper towel through the second roller assembly 300.

[0043] During the transmission of the paper towel, the first roller assembly 200 can release liquid to moisten the paper towel, while the second roller assembly 300 can heat the paper towel to provide warm wet paper towel for user convenience.

[0044] In some embodiments of the present invention, Figure 3 As shown, the first roller assembly 200 and the second roller assembly 300 are arranged front to back in the conveying direction of the paper towels, and the first roller assembly 200 is closer to the second paper outlet 130 than the second roller assembly 300 .

[0045] In the conveying direction of the paper towel, the paper towel is output from the second paper outlet 130. The first roller assembly 200 first moistens the paper towel, and then the second roller assembly 300 contacts the moistened paper towel to heat the moistened paper towel, making it safer and more reliable to use.

[0046] In some embodiments of the present invention, Figure 3As shown, the paper feeding module also includes at least one third roller assembly 400, which is rotatably arranged on the shell 100. The outer wall of the third roller assembly 400 can contact the paper towel, and the third roller assembly 400 and the first roller assembly 200 respectively contact the two side surfaces of the paper towel one by one, and the first roller assembly 200 and the third roller assembly 400 are arranged opposite to each other to convey the paper towel.

[0047] The third roller assembly 400 can cooperate with the first roller assembly 200 to define an area allowing paper towels to pass through, so that the outer wall of the first roller assembly 200 can be better pressed against the surface of the paper towels, and liquid can better penetrate the paper towels.

[0048] In some embodiments of the present invention, the paper feeding module also includes at least one fourth roller assembly 500, which is rotatably arranged on the shell 100. The outer wall of the fourth roller assembly 500 can contact the paper towel, and the fourth roller assembly 500 and the second roller assembly 300 respectively contact the two side surfaces of the paper towel one by one, and the second roller assembly 300 and the fourth roller assembly 500 are arranged opposite to each other to convey the paper towel.

[0049] Similarly, the fourth roller assembly 500 can cooperate with the second roller assembly 300 to define an area allowing the paper towel to pass through, so that the outer wall of the second roller assembly 300 can be better pressed against the surface of the paper towel, so that the second roller assembly 300 can better transfer heat to the paper towel.

[0050] In some embodiments of the present invention, Figure 4 As shown, the first roller assembly 200 and the second roller assembly 300 are in contact with two sides of the paper towel in a one-to-one correspondence, and the first roller assembly 200 and the second roller assembly 300 are arranged opposite to each other to convey the paper towel.

[0051] The first roller assembly 200 and the second roller assembly 300 cooperate to define an area allowing the paper towel to pass through, so that the outer wall of the first roller assembly 200 and the outer wall of the second roller assembly 300 can both be pressed against the surface of the paper towel well. While the first roller assembly 200 humidifies the paper towel, the second roller assembly 300 can heat the humidified position.

[0052] In some embodiments of the present invention, Figure 6As shown, the first roller assembly 200 includes an end cover 210 and a first set of rollers 220. A water storage tank is provided in the first set of rollers 220. One end of the first set of rollers 220 is provided with an opening connected to the water storage tank. The end cover 210 is provided at the opening and the first set of rollers 220 is rotatably mounted on the end cover 210 to define a first water storage chamber. The seepage port 240 is circumferentially arranged on the outer wall of the first set of rollers 220. The first set of rollers 220 is rotatably set on the shell 100, and the end cover 210 can be fixed to the shell 100. The end cover 210 is provided with a liquid inlet connected to the first water storage chamber, and the liquid inlet can be connected to the water supply source through a water pipe. Thus, the first roller assembly 200 can rotate to humidify the paper towels while supplying water to the first water storage chamber.

[0053] In some embodiments of the present invention, Figure 7 As shown, the first heating element 310 is rod-shaped and is disposed on the housing 100 . The second roller assembly 300 is rotatably sleeved on the first heating element 310 . The second roller assembly 300 is in thermal contact with the first heating element 310 .

[0054] The first heating element 310 is fixedly arranged on the shell 100, and the power supply can be connected to the first heating element 310 through a wire to supply power to the first heating element 310. The first heating element 310 will not rotate relative to the shell 100, so the power supply is more stable and reliable. Specifically, the first heating element 310 can be a resistive heating rod, or a resistance wire or a semiconductor heating sheet arranged on a rod-shaped bracket. The second roller assembly 300 can also include a second set of rollers 320, which are rotatably mounted on the first heating element 310. The second set of rollers 320 can be made of a heat-conductive metal material. The heat emitted by the first heating element 310 can be transferred to the paper towel through the second set of rollers 320.

[0055] In some embodiments of the present invention, Figure 8 、 9 As shown in FIG. 10 , the first roller assembly 200 is provided with a liquid absorbing member 260 at the liquid seepage port 240 . The liquid absorbing member 260 can absorb the liquid in the first liquid storage chamber 230 and can release the liquid when the liquid absorbing member 260 is under pressure.

[0056] It should be noted that the two ends of the liquid-absorbing member 260 protrude from the outer wall of the first liquid storage chamber 230 and the first roller assembly 200 respectively. The liquid in the first liquid storage chamber 230 can be absorbed by the liquid-absorbing member 260. Then, when the paper towel is pressed against the liquid-absorbing member 260, the liquid-absorbing member 260 can precipitate liquid to humidify the paper towel. Therefore, the liquid in the first liquid storage chamber 230 is not easy to leak in large quantities from the liquid seepage port 240, and the liquid-absorbing member 260 can precipitate liquid more evenly. At the same time, the liquid-absorbing member 260 can be made of materials such as sponge, cotton cloth, and non-woven fabric, which can play a buffering role, thereby reducing the noise caused by the first roller assembly 200 and the paper towel during humidification.

[0057] In some embodiments of the present invention, Figure 9 、 10 As shown, the first roller assembly 200 is provided with an absorbent core 250 in the first liquid storage chamber 230, and there are multiple absorbent parts 260, and the multiple absorbent parts 260 are connected to the absorbent core 250. The absorbent core 250 can absorb the liquid in the first liquid storage chamber 230 and then transfer it to each absorbent part 260, reducing the liquid flowing in the first liquid storage chamber 230, thereby further reducing the noise emitted by the first roller assembly 200.

[0058] In some embodiments of the present invention, the housing 100 is further provided with a driving module (not shown in the figure), which is connected to the first roller assembly 200 to drive the first roller assembly 200 to rotate.

[0059] Among them, the driving module drives the first roller assembly 200 to rotate, so that the first roller assembly 200 can drive the paper towel forward. Of course, in some embodiments of the present invention, the driving module can also drive any one of the second roller assembly 300, the third roller assembly 400 and the fourth roller assembly 500 to rotate.

[0060] Specifically, the driving module may include a motor and a planetary gear structure coordinated with the motor, thereby driving the paper feeding module to operate.

[0061] In some embodiments of the present invention, the user can also draw out a paper towel from the first paper outlet 120. Since the first roller assembly 200, the second roller assembly 300, etc. are in contact with the paper towel, the movement of the paper towel will also drive the first roller assembly 200 to rotate, thereby humidifying the paper towel. This process does not require an additional drive module to drive the first roller assembly 200 and the second roller assembly 300.

[0062] In some embodiments of the present invention, Figure 2 、 11 As shown, the shell 100 is also provided with a liquid supply module 600, which is connected to the first liquid storage chamber 230 to supply liquid to the first liquid storage chamber 230, so that a certain amount of liquid can be stored in the liquid supply module 600 to be provided to the first liquid storage chamber 230, thereby improving the endurance of the humidification function of the wet wipes machine.

[0063] In some embodiments of the present invention, the liquid supply module 600 includes a second heating element 620 and an infusion component 610. The shell 100 is provided with a second liquid storage chamber 640. The second heating element 620 is arranged in the shell 100 so as to be able to heat the liquid in the second liquid storage chamber 640. The infusion component 610 is respectively connected to the second liquid storage chamber 640 and the first liquid storage chamber 230 so as to be able to transfer the liquid in the second liquid storage chamber 640 to the first liquid storage chamber 230. Therefore, this design does not require the addition of a second roller assembly 300 and a first heating element 310. The second heating element 620 directly heats the liquid in the second liquid storage chamber 640, and then the heated liquid is used to humidify the paper towel to form a warm wet paper towel. The structure is simple and practical and convenient.

[0064] In some embodiments of the present invention, Figure 11 As shown, the shell 100 is provided with a partition 630 to separate the second liquid storage chamber 640 into a first chamber 641 and a second chamber 642. The second chamber 642 is located below the first chamber 641. The infusion component 610 is connected to the second chamber 642. The partition 630 is provided with at least one leakage hole 631 respectively connecting the first chamber 641 and the second chamber 642. The second heating element 620 can heat the liquid in the second chamber 642.

[0065] Specifically, the infusion component 610 can be composed of a liquid pump, and the liquid inlet end of the liquid pump is connected to the second cavity 642 through an infusion tube. It should be noted that the port where the infusion tube is connected to the second cavity 642 is generally located relatively below the second cavity 642. There are multiple leakage holes 631, and the aperture of the leakage holes 631 is relatively small. Under the action of water tension, the water in the hole forms a diaphragm, and liquid is added to the first cavity 641. The second cavity 642 is relatively sealed and the air pressure of the second cavity 642152 is roughly the same as that of the outside world. The liquid in the first cavity 641 is not easy to leak into the second cavity 642. When the liquid pump is running and the liquid or part of the air in the second cavity 642 is extracted, a negative pressure is formed in the second cavity 642 to break the balance, and the liquid in the first cavity 641 can fall from the leakage hole 631 into the second cavity 642 for replenishment.

[0066] The second heating element 620 can heat the liquid in the second cavity 642 in a targeted manner without affecting the liquid in the first cavity 641, thereby achieving calibrated and quantitative heating, improving heating efficiency, and saving energy.

[0067] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
