[0016] 1. A vertical liquid storage tank body is provided with a rotating mechanism. When a driving motor drives a driving screw to rotate on a bearing, under the action of a planetary gear, the sun gear on the bearing rotates in opposite directions to the gear sleeve.

[0018] 3. This vertical liquid storage tank body is provided with bearings, and the bearings provide load-bearing fulcrums for the driving screw and the sliding rod on the gear sleeve. Under the action of the bearings, the bottom of the driving screw is stabilized to rotate at the bottom of the liquid storage tube body, thereby preventing the driving screw from shaking during rotation, which would cause the brush on the sliding rod to have insufficient contact with the inner wall of the liquid storage tube body. This achieves the purpose of stabilizing the rotation of the driving screw and making the brush fully contact with the inner wall of the liquid storage tube body, thereby improving the cleaning efficiency and reducing harm to the human body.

At this time, the screw sleeve 1103 on the screw and the slider 1110 on the sliding rod 1109 can slide on the screw and the sliding rod 1109 respectively, thereby achieving the purpose of automatically cleaning the tank body and improving the cleaning efficiency.

[0032] A slider 1110 is slidably connected to one side of the slide rod 1109, and the slider 1110 can slide freely on the slide rod 1109. A connecting rod 1111 is fixedly connected to one side of the slider 1110, and one end of the connecting rod 1111 is fixedly connected to the screw sleeve 1103. The slider 1110 is fixedly connected to the screw sleeve 1103 through the connecting rod 1111. When the screw sleeve 1103 moves on the driving screw 1101, the screw sleeve 1103 drives the slider 1110 to slide on the slide rod 1109.

[0033] The cleaning mechanism includes a brush 1201, one side of the brush 1201 is fixedly connected to a brush plate 1202, the shape of the brush plate 1202 is set to be triangular, one end of the brush plate 1202 is fixedly connected to a fixed rod 1203, and the center position of one end of the fixed rod 1203 is fixedly connected to a rotating rod 1204.

[0034] One end of the rotating rod 1204 is movably connected to a support rod 1205, the support rod 1205 and the connecting rod 1111 are respectively located on both sides of the slider 1110, the upper end of one side of the support rod 1205 is fixedly connected to a rotating motor 1206, the left and right ends of the rotating motor 1206 are welded to the support rod 1205, one side of the rotating motor 1206 is fixedly connected to a rotating shaft 1207, and the center position of one end of the rotating shaft 1207 is fixedly connected to a rotating gear 1208.

[0035] One end of the support rod 1205 is fixedly connected to a first clamping plate 1209, one side of the first clamping plate 1209 is fixedly and movably connected to a passive gear 1210, one side of the passive gear 1210 is fixedly connected to a second clamping plate 1211, the first clamping plate 1209 and the second clamping plate 1211 are set to be cylindrical with the same radius and the thickness of the first clamping plate 1209 is greater than the thickness of the second clamping plate 1211, the radius of the first clamping plate 1209 is greater than the radius of the passive gear 1210, one side of the passive gear 1210 is meshed and connected with the rotating gear 1208, the first clamping plate 1209 and the second clamping plate 1211 clamp the passive gear 1210 between the first clamping plate 1209 and the second clamping plate 1211, increase the contact area between the passive gear 1210 and the rotating gear 1208, and ensure the operation between the passive gear 1210 and the rotating gear 1208.

[0036] By setting the first clamping plate 1209, when the rotating gear 1208 drives the passive gear 1210 to rotate, under the action of the first clamping plate 1209 and the second clamping plate 1211, the bottom of the rotating gear 1208 is restricted between the first clamping plate 1209 and the second clamping plate 1211, so as to avoid the shaking of the rotating gear 1208 during rotation, resulting in incomplete contact between the rotating gear 1208 and the passive gear 1210, thereby achieving the purpose of stabilizing the rotation of the rotating gear 1208 and making the rotating gear 1208 and the passive gear 1210 effectively contact.

[0037] The first clamping plate 1209 is internally slidably connected to a rotating block 1212, the outer side of the rotating block 1212 is completely consistent with the inner wall of the first clamping plate 1209, the center position of one side of the rotating block 1212 is fixedly connected to the rotating rod 1204, one side of the rotating rod 1204 is fixedly connected to the passive gear 1210, and the other side of the rotating rod 1204 is slidably connected to the second clamping plate 1211.

[0038] By setting the rotating block 1212, when the rotating gear 1208 drives the passive gear 1210 on the rotating rod 1204 to rotate, the rotating rod 1204 drives the rotating block 1212 to rotate inside the first clamping plate 1209. Under the action of the rotating block 1212, the rotating rod 1204 on the rotating block 1212 is prevented from falling out of the first clamping plate 1209, thereby achieving the purpose of stabilizing the rotation of the rotating rod 1204.

[0039] The working principle of this embodiment is as follows: close the liquid inlet valve 4 on one side of the liquid storage tube body 1 to drain the liquid inside the liquid storage tube body 1, turn on the drive motor 2, the drive motor 2 drives the drive screw 1101 to rotate on the bearing 1106, the drive screw 1101 drives the screw sleeve 1103 to move on the drive screw 1101, the drive screw 1101 drives the sun gear 1105 to rotate on the bearing 1106, the sun gear 1105 drives the planetary gear 1107 to rotate on the bearing 1106, the planetary gear 1107 drives the gear sleeve 1108 to rotate on the bearing 1106, and the rotation direction of the gear sleeve 1108 is completely opposite to the rotation direction of the sun gear 1105, so the slide bar 1109 on the gear sleeve 1108 can rotate around the center of the drive screw 1101, and the rotation direction of the slide bar 1109 is opposite to the rotation direction of the drive screw 1101. At this time, the screw sleeve 1103 can drive The slider 1110 on the connecting rod 1111 slides on the slide rod 1109 to turn on the rotating motor 1206 on the supporting rod 1205. The rotating motor 1206 drives the rotating shaft 1207 to rotate. The rotating shaft 1207 drives the rotating gear 1208 to rotate between the first clamping plate 1209 and the second clamping plate 1211. The rotating gear 1208 drives the passive gear 1210 to rotate. The passive gear 1210 drives the rotating rod 1204 to rotate inside the second gear. The rotating rod 1204 drives the rotating block 1212 to rotate inside the first clamping plate 1209. The rotating rod 1204 drives the fixed rod 1203 to rotate. The fixed rod 1203 drives the brush plate 1202 to rotate. The brush plate 1202 drives the brush 1201 to rotate on the inner wall of the liquid storage tube body 1 to clean the residual liquid on the inner wall of the liquid storage tube body 1, so as to achieve the purpose of automatically cleaning the tank body, improving the cleaning efficiency and reducing harm to the human body.

[0040] Example 2

[0041] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 5 A fixing sleeve 13 is fixedly connected to the upper end of the first clamping plate 1209 , and the interior of the fixing sleeve 13 is movably connected to the rotating shaft 1207 . The rotating shaft 1207 can rotate freely in the fixing sleeve 13 , and one side of the fixing sleeve 13 is movably connected to the rotating gear 1208 .

[0042] The working principle of this embodiment is as follows: when the rotating motor 1206 drives the rotating gear 1208 on the rotating shaft 1207 to rotate, since the length of the rotating shaft 1207 is too long and the rotating shaft 1207 follows the fixed rod 1203 to rotate around the driving screw 1101, it is easy for the rotating shaft 1207 to swing left and right, resulting in insufficient contact between the rotating gear 1208 and the passive gear 1210, and a poor cleaning effect. This problem can be solved by setting a fixed sleeve 13. By setting the fixed sleeve 13, when the rotating motor 1206 drives the rotating gear 1208 on the rotating shaft 1207 to rotate, the fixed sleeve 13 fixes one side of the rotating shaft 1207 on the first clamping plate 1209 to avoid the problem of shaking of the rotating shaft 1207, thereby achieving the purpose of stabilizing the rotation of the rotating shaft 1207, making the rotating gear 1208 fully contact with the passive gear 1210, and improving the cleaning effect.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
