[0002] As a container for holding liquids, cups play an important role in people's daily lives. However, people are not always able to clean the stains inside the cups after daily use. Existing cups are slender in structure, and most cups have small radial dimensions. Manual cleaning is difficult to achieve good cleaning effects, and prolonged use of cups with debris inside can affect people's health. The traditional way to clean cups is by hand. When the internal curves of the cup are complex, the cup mouth is small, and the bottom is deep, manual cleaning is time-consuming and laborious, and the cleaning effect is difficult to guarantee. At the same time, prolonged contact of hands with detergent can cause certain damage to the hands. On the other hand, with the development of society, manual cleaning no longer meets the pursuit of high-quality life for modern people. With the advent of the smart home era, automatic cleaning of cups will be an inevitable trend. The existing cup washers on the market are of few types, single functions, rough designs, poor cleaning effects, low popularity, and poor user experience. Therefore, people have made cup washers for cleaning the bottom or the lower inner wall of a cup. However, existing cup washers mainly include a long handle with a sponge or bristles disposed at one end of the handle. The sponge or bristles of such cup washers are fixed in size and are difficult to adapt to the cleaning of cups with complex inner curved surfaces. In addition, existing electric cup washers can only rotate to clean the bottom or inner wall of the cup, and cannot move up and down to clean the inner wall and bottom of the cup.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2As shown, the cup washer of the present invention is characterized by comprising a driver 1, a main shaft 2, and a brush rod 5. The driver 1 is connected to one end of the main shaft 2 and drives the main shaft 2 to rotate. The other end of the main shaft 2 is slidably connected to one end of the brush rod 5, and the brush rod 5 can rotate with the main shaft 2. The other end of the brush rod 5 is provided with a brush head 15. The device also includes a sliding controller, which allows the brush rod 5 to slide back and forth along the axis of the main shaft 2. As will be understood by those skilled in the art, the device connects one end of the main shaft 2 to the driver 1 and the other end to the brush rod 5, ensuring that the brush rod 5 rotates with the main shaft 2. Simultaneously, the brush rod 5 can slide along the axis of the main shaft 2 via the sliding controller. The combined motion of these two motions causes the brush head 15 to move in a helical motion. In actual use, the back-and-forth sliding of the brush rod 5 can simultaneously clean the cup wall and bottom, eliminating the need for manual up and down movement, making it easier to use.

[0020] Preferably, the above device further comprises an outer cylinder 12, a partition 121 is radially provided on the inner wall of the upper portion of the outer cylinder 12, a through hole is provided in the middle of the partition 121, and the main shaft 2 can be fixed on the partition 121 and is rotatably connected to the partition 121. It will be understood by those skilled in the art that the present device preferably further comprises an outer cylinder 12, and the outer cylinder 12 is used to position the main shaft 2, so that the main shaft 2 can be suspended on the partition on the upper portion of the outer cylinder 12, and the main shaft 2 can be rotatably connected to the partition. Preferably, the partition is radially arranged with the outer cylinder 12 to ensure that the axes of the main shaft 2 and the outer cylinder 12 coincide with each other, thereby preventing the main shaft 2 from swinging when rotating.

[0021] Preferably, the sliding controller in the above device includes a planetary gear set 8, an inner cylinder 4 and a support plate 6, the planetary gear set 8 is arranged in the upper inner part of the outer cylinder 12, and the outer cylinder 12 can rotate with the main shaft 2 through the planetary gear set 8, the inner cylinder 4 is sleeved on the main shaft 2 and can slide axially along the main shaft 2; the inner cylinder 4 is a hollow box structure, the upper end of the brush rod 5 is flanged to form a flange connection plate 51, and the lower bottom inner side surface of the inner cylinder 4 is located below the flange connection plate 51 and is in contact with it; the support plate 6 is obliquely arranged at the inner lower part of the outer cylinder 12 and is connected to the outer cylinder 12, and a spherical head cylinder 11 is provided on the outer side of the lower bottom surface of the inner cylinder 4, and the lower end of the spherical head cylinder 11 is in contact with the upper end surface of the support plate 6. Those skilled in the art will appreciate that the present device further defines the specific structure of the sliding controller, which primarily includes a planetary gear set 8, an inner cylinder 4, and a support plate 6. The planetary gear set 8 is disposed in the upper inner portion of the outer cylinder 12, so that the outer cylinder 12 can rotate with the spindle 2 through the planetary gear set 8, which in turn causes the outer cylinder 12 to rotate. Preferably, the inner cylinder 4 is a hollow box structure, and more preferably, a cylindrical box structure with sealed ends. A spherical cylinder 11 is disposed on the outer side of the lower bottom surface of the inner cylinder 4, and the spherical cylinder 11 can preferably be disposed parallel to the spindle 2. The support plate 6 is disposed obliquely in the lower inner portion of the outer cylinder 12 and connected to the outer cylinder 12, so that the support plate 6 can rotate with the outer cylinder 12 along with the spindle 2. The lower end of the spherical cylinder 11 is in contact with the upper end surface of the support plate 6. Due to the oblique arrangement of the support plate 6, the contact point between the spherical cylinder 11 and the support plate 6 changes as the support plate 6 rotates, thereby enabling the inner cylinder 4 to slide back and forth up and down along the axial direction of the spindle 2. The upper end of the brush rod 5, which is close to the end face of the main shaft 2, is flanged to form a flange connection plate 51. The inner side surface of the lower bottom of the inner cylinder 4 is located below the flange connection plate 51 and is in contact with it. The brush rod 5 is actually prevented from sliding down by the inner cylinder 4. When the inner cylinder 4 slides up and down along the axis of the main shaft 2, the brush rod 5 will also slide up and down along the axis of the main shaft 2, so that the bristle head at the lower end of the brush rod 5 moves in a spiral, thereby achieving the purpose of automatically cleaning the bottom and inner wall of the cup. Since the brush rod 5 rotates with the main shaft 2, in order to reduce the friction between the contact side of the connecting flange 51 and the inner cylinder 4, the device can preferably set a ball at the contact point between the connecting flange 51 and the inner cylinder 4, so that the connecting flange 51 and the inner cylinder 4 are in rolling contact to reduce friction, thereby reducing wear on the contact side.The planetary gear set 8 is of existing technology, and may preferably specifically include a support cover plate 81, a driving gear 82, a driven gear 83 and an annular rack 84. The annular rack 84 is arranged on the inner wall of the upper part of the outer cylinder 12, and the driving gear 82 is arranged on the main shaft 2 through the shaft shoulder and the support cover plate 81, and can rotate with the main shaft 2. The support cover plate 81 is set on the main shaft 2 through a bearing sleeve, and the lower end of the support cover plate 81 is symmetrically provided with a driven gear 83 fixed shaft. The driven gear 83 is suspended below the support cover plate 81 through a fixed shaft, and the two sides of the driven gear 83 are kept engaged with the driving gear 82 and the annular rack 84 respectively, so that the actual main shaft 2 rotates, the driving gear 82 rotates accordingly, thereby driving the driven gear 83 to rotate, and finally driving the annular rack 84 to rotate. Since the annular rack 84 is fixedly connected to the outer cylinder 12, the outer cylinder 12 also rotates accordingly, causing the support plate 6 to rotate together. Since the diameter of the annular rack 84 is much larger than the driving gear 82 and the driven gear 83, the actual operating speed of the outer cylinder 12 is much lower than the speed of the main shaft 2 to achieve a speed reduction function, so that the axial sliding speed of the brush rod 5 is not too fast.

[0022] Preferably, in the above-mentioned device, at least one chute 21 is provided on the outer wall of the lower end of the main shaft 2 and arranged axially along the main shaft 2.

It will be understood by those skilled in the art that, in this device, the brush rod 5 and the main shaft 2 are preferably connected by the clamping block 52 and the chute 21, so that the brush rod 5 and the main shaft 2 can rotate synchronously and the brush rod 5 can slide along the chute 21. It is preferred that the chute 21 is two symmetrical ones, and the upper part of the brush rod 5 is symmetrically provided with an adaptive blind hole with a clamping block 52. In actual use, the lower end of the main shaft 2 needs to be inserted into the blind hole, and the clamping block 52 is located in the chute 21, so that the main shaft 2 and the brush rod 5 can be slidably connected.

[0023] Preferably, the tilt angle of the support plate 6 in the above device is adjustable. Those skilled in the art will appreciate that, since cups vary in depth, the present device is designed to accommodate cups of varying depths.

To facilitate the insertion of the brush rod 5, the device is preferably provided with through holes in the lower cover plate 18 and the support plate 6. The diameter of the through holes should be larger than the diameter of the brush rod 5 to prevent the brush rod 5 from contacting the support plate 6 and affecting its use. The adjusting screw 13 extends into the threaded hole and is threadedly connected to the lower cover plate 18, and the lower wall of the inclined upper end is in contact with the inserted end of the adjusting screw 13. The purpose of changing the inclination angle of the support plate 6 is achieved by twisting the adjusting screw 13.

[0025] Preferably, the device further includes at least two guide posts 17 having an inverted T-shaped structure. The guide posts 17 are parallel to the axis of the main shaft 2.
