[0028] Please see Figures 1 to 6This utility model provides a tissue vending machine 100, which includes a housing 1 with a paper outlet 2. The vending machine also includes a helical spring 3 housed within the housing 1, one end of which is connected to a drive mechanism 4. The helical spring 3 comprises several coils 31, with tissues 32 placed between the coils 31. The tissues 32 are small packs of tissues for easy carrying. The vending machine also includes an upper baffle 5 positioned above the helical spring 3 to prevent the tissues 32 from moving upwards and to prevent the tissues 32 from being moved above the coils 31 during rotation of the helical spring 3. The vending machine 100 also includes a lower baffle 6, which is disposed below the helical spring 3 to prevent the tissue paper 32 from moving downward and to prevent the tissue paper 32 from being moved out of the area below the coil 31 during the rotation of the helical spring 3. The vending machine 100 also includes a front baffle 7, which is disposed in front of the helical spring 3 to prevent the tissue paper 32 from moving forward and to prevent the tissue paper 32 from being moved out of the area in front of the coil 31 during the rotation of the helical spring 3. The vending machine 100 also includes a rear baffle 8, which is disposed behind the helical spring 3 to prevent the tissue paper 32 from moving backward and to prevent the tissue paper 32 from being moved out of the area behind the coil 31 during the rotation of the helical spring 3.

[0029] In one embodiment, the housing 1 includes a rear housing 11, the rear baffle 8 is the rear housing 11, and the helical spring 3 is disposed adjacent to the rear housing 11 with a spacing greater than 0 between the helical spring 3 and the rear housing 11. This arrangement allows the helical spring 3 to rotate normally, while the spacing between the helical spring 3 and the rear housing 11 is less than 4cm. This arrangement also prevents the paper towel 32 from moving behind the coil 31 during the rotation of the helical spring 3.

[0030] In one embodiment, the housing 1 further includes a front housing 12, which is disposed opposite to the rear housing 11. An upper baffle 5 is disposed on the front housing 12 and connected to it, for example, in a fixed configuration. The distance between the helical spring 3 and the upper baffle 5 is greater than zero, allowing the helical spring 3 to rotate normally. However, the distance between the helical spring 3 and the upper baffle 5 is less than 4 cm, preventing the paper towel 32 from moving above the coil 31 during rotation.

[0031] In one embodiment, the lower baffle 6 is disposed on the rear housing 11, and the lower baffle 6 is connected to the rear housing 11, for example, by a fixed connection. The distance between the helical spring 3 and the lower baffle 6 is greater than zero. This arrangement allows the helical spring 3 to rotate normally. The distance between the helical spring 3 and the lower baffle 6 is less than the height of the tissue 32. This arrangement prevents the tissue 32 from moving below the coil 31 during the rotation of the helical spring 3.

[0032] In one embodiment, the front baffle 7 can be connected to the front housing 12, for example, by being fixedly connected. The front baffle 7 can also be connected to the lower baffle 6, for example, by being fixedly connected, or the front baffle 7 and the lower baffle 6 can be integrated into one unit.

[0033] In one embodiment, the drive mechanism 4 includes a support member 41, which is connected to one end of the helical spring 3. The helical spring 3 is sleeved on the outer surface of the support member 41 so that the helical spring 3 is fixedly connected to the support member 41. The drive mechanism 4 drives the support member 41 to rotate, thereby driving the helical spring 3 to rotate.

[0034] In one embodiment, the drive mechanism 4 includes a motor 42, a primary gear 43, a secondary gear 44, a tertiary gear 45, a first transmission wheel 46, a second transmission wheel 47, and a third transmission wheel 48. The first transmission wheel 46 is connected to the motor 42. The motor 42 includes a rotating shaft. The first transmission wheel 46 is sleeved on the outer surface of the rotating shaft to achieve connection between the motor 42 and the first transmission wheel 46. The first transmission wheel 46 is connected to the primary gear 43. The first transmission wheel 46 includes several gears, and the primary gear 43 also includes several gears. The first transmission wheel 46 and the primary gear 43 are connected by gear meshing. The primary gear 43 and the secondary gear 44 are connected by the second transmission wheel 47. The primary gear 43 and the second transmission wheel 47 are coaxially connected. The rotation of the primary gear 43 drives the rotation of the second transmission wheel 47. The secondary gear 44 and the second transmission wheel 47 are connected by gear meshing. The rotation of the first-stage gear 43 drives the second transmission wheel 47 to rotate, which in turn drives the second-stage gear 44 to rotate. The second-stage gear 44 and the third-stage gear 45 are connected by a third transmission wheel 48. The second-stage gear 44 and the third transmission wheel 48 are coaxially connected. The rotation of the second-stage gear 44 drives the third transmission wheel 48 to rotate. The third-stage gear 45 and the third transmission wheel 48 are connected by gear meshing. The rotation of the second-stage gear 44 drives the third transmission wheel 48 to rotate, which in turn drives the third-stage gear 45 to rotate. The third-stage gear 45 and the support member 41 are connected by a rotating member 49. One end of the rotating member 49 is connected to the third-stage gear 45, and the other end of the rotating member 49 is connected to the support member 41. The support member 41 is connected to the helical spring 3. The rotation of the third-stage gear 45 drives the support member 41 to rotate through the rotating member 49, which in turn drives the helical spring 3 to rotate, thereby causing the paper towel 32 to move forward and fall into the paper outlet 2.

[0035] Through the structure of the drive mechanism 4 described above, the spiral distance of the spiral spring 3 can be precisely controlled, so that the paper towel 32 can fall accurately into the paper outlet 2.

[0036] In one embodiment, the first-stage gear 43 and the second-stage gear 44 have the same diameter and number of teeth, and the parameters and specifications of the first-stage gear 43 and the second-stage gear 44 are approximately the same. The diameter and number of teeth of the first-stage gear 43 and the second-stage gear 44 are smaller than the diameter and number of teeth of the third-stage gear 45, which can precisely control the spiral distance of the helical spring 3, so that the paper towel 32 can fall accurately into the paper outlet 2.

[0037] In one embodiment, the number of teeth of the primary gear 43 and the secondary gear 44 is 30-50, and the number of teeth of the primary gear 43 and the secondary gear 44 can be 30, 40, or 50. The number of teeth of the tertiary gear 45 is 60-100, and the number of teeth of the tertiary gear 45 can be 60, 80, or 100. By setting the number of teeth of the primary gear 43, the secondary gear 44, and the tertiary gear 45, the spiral distance of the helical spring 3 can be precisely controlled, so that the paper towel 32 can fall accurately into the paper outlet 2.

[0038] In one embodiment, the first transmission wheel 46, the second transmission wheel 47, and the third transmission wheel 48 have the same diameter and number of teeth, which makes the first transmission wheel 46, the second transmission wheel 47, and the third transmission wheel 48 more stable when driving the first-stage gear 43, the second-stage gear 44, and the third-stage gear 45.

[0039] In one embodiment, the tissue vending machine 100 further includes a lithium battery 9 comprising four cells, which is electrically connected to the motor 42 to drive the motor 42 to rotate.

[0040] In this utility model, unless otherwise explicitly specified or limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a mechanical connection or an electrical connection; they can be a direct connection or an indirect connection through an intermediate medium; they can be a connection within two components, or merely surface contact, or a surface contact connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
