Detailed Description

The following describes in detail specific embodiments of the present invention. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.

The greatest innovation point of the invention is that water is used as power to provide a power source for the pot brushing device, and the traditional electric mode is replaced. As shown in fig. 1, the hydraulic drive pot brushing device comprises a power assembly 1, a brush part 2 and a supporting assembly 3 for supporting the power assembly 1 and the brush part 2. The power assembly 1 is connected to the brush part 2 and can drive the brush part 2 to move.

As shown in fig. 2 and 3, the power assembly 1 is a schematic structural diagram, and the power assembly 1 includes a water inlet pipe 11, a reversing valve 12, a first water pipe 13, a second water pipe 14, a hydraulic cylinder 15, a rack 16, a water outlet pipe 17, and a power transmission mechanism 18. The hydraulic cylinder 15 is connected with the reversing valve 12 through the first water pipe 13 and the second water pipe 14, one end of the water inlet pipe 11 and one end of the water outlet pipe 17 are both connected with the reversing valve 12, and the reversing valve 12 preferably adopts a two-position two-way reversing valve. The hydraulic cylinder 15 is connected with the power transmission mechanism 18 through the rack 16, and the rack 16 is fixedly connected with a piston rod 151 of the hydraulic cylinder 15 and is arranged parallel to the piston rod 151.

The hydraulic drive pot brushing device inputs water with enough water pressure into the power assembly 1 from the water inlet pipe 11, specifically, the water enters the hydraulic cylinder 15 through the reversing valve 12, pushes the piston rod 151 to move, so as to drive the rack 16 to move, then transmits the motion of the rack 16 to the power transmission mechanism 18, and the power transmission mechanism 18 transmits power to the brush part 2 after power conversion, so as to realize the cleaning function. Therefore, the hydraulic drive pot brushing device replaces the traditional pot brushing device taking electricity as a power source, and can ensure that the pot brushing process is safer and more energy-saving on the basis of automatically brushing the pot and liberating labor force. The hydraulic drive pot brushing device is not only suitable for brushing a pot, but also suitable for brushing a bowl, a basin and the like.

Preferably, a detergent container 19 is disposed at the other end of the water outlet pipe 17, and a water spray head 20 is disposed on the detergent container 19. The cleaning agent container 19 can be added with a proper amount of cleaning solution, so that the cleaning effect is enhanced by the detergent mixed solution sprayed from the water spray head 20.

Further preferably, the power transmission mechanism 18 includes a power transmission head 184, a transmission shaft 181, a gear 183 disposed at one end of the transmission shaft 181, and a gear plate 182 disposed at the other end of the transmission shaft 181, wherein the gear 183 is engaged with the rack 16, and the gear plate 182 is engaged with the power transmission head 184. This enables the power of the power assembly 1 to be transmitted to the brush portion 2.

In theory, the reversing valve 12 can be manually reversed. In order to facilitate the operation and realize the automatic reversing of the reversing valve 12, a reversing mechanism is arranged for the reversing valve 12. Specifically, the reversing mechanism comprises two groups of reversing components, a reversing groove 37, a reversing shifting block 33 and a rod 35, and the two groups of reversing components are arranged in a bilateral symmetry mode and are located in the reversing groove 37. The reversing shifting block 33 is located between the two groups of reversing components, and the reversing components can move along the axial direction of the rod 35 under the driving of external force so as to alternately shift the reversing shifting block 33. Further, the reversing assembly comprises a spring block hook 31, a spring block 32, a compression spring 34, a stop 36 and a tension spring 38. The spring block 32, the compression spring 34 and the stopper 36 are all sleeved on the rod 35 and can move along the axial direction of the rod 35. The compression spring 34 is located between the bullet piece 32 and the dog 36, one end of the compression spring is connected with the bullet piece 32, the other end of the compression spring is connected with the dog 36, one end of the tension spring 38 is connected with the hook part of the bullet piece hook 31, the other end of the tension spring is connected with the reversing groove 37, and the tension spring 38 and the bullet piece hook 31 are used for providing certain resistance for the movement of the bullet piece 32 (the tension spring 38 has a tendency that the bullet piece hook 31 hooks the bullet piece 32). The reversing shifting block 33 is positioned between the two groups of reversing components. The stop 36 is fixedly connected to the piston rod 151, so that the stop 36 can move along with the movement of the piston rod 151.

The reversing of the reversing mechanism is achieved in such a way that, as shown in fig. 2 and 4, when the piston rod 151 starts moving to the right, the rack 16 and the stopper 36 also start moving, and at this time, due to the action of the block hook 31, the block 32 cannot move to the right, and the compression spring 34 therebetween is compressed. When the stop 36 continues to move to the right until it contacts the bullet block hook 31 and pushes it, the bullet block hook 31 will release the restriction on the bullet block 32, so that it will be ejected by the compression spring 34 and push the reversing block 33 to shift to the right to complete the reversing. After the reversing assembly on the left side finishes reversing, the piston rod 151 moves in the opposite direction, that is, to the left, and the reversing assembly on the right side finishes reversing according to the above steps (the reversing shifting block 33 is shifted to the left) while the elastic block 32 is pulled to the left to reset. The above steps are alternately performed, and the direction change is performed circularly, so that the rack 16 continuously moves left and right back and forth, and the continuous forward and reverse rotation of the brush part 2 is realized. The above-mentioned "left" and "right" refer to the orientations in the state of fig. 4.

Of course, if it is desired to omit the reversing mechanism, an automatic reversing valve, such as a solenoid reversing valve, may be substituted for the reversing valve 12 described above.

In the present invention, the brush part 2 may have various options, and a specific structure of the brush part 2 is provided herein. The brush part 2 is different from the existing brush part in that the movement is a compound movement during brushing, namely, the brush part performs an expansion and contraction movement while performing a rotation movement. The pot surface cleaning device has the advantages that the pot surface can be cleaned to every place as much as possible, the specific internal structure is shown in figure 5, and the brush part 2 comprises a main rotating shaft 21, an expansion rod 22, a brush head 23, a sleeve 24, an extension spring 25, a nut sleeve 26 and a central brush shaft 28; the main rotating shaft 21 is partially provided with a thread 27, one end of the thread 27 is connected with the power transmission mechanism 18, the other end of the thread is connected with the central brush shaft 28, the main rotating shaft 21 and the central brush shaft 28 are coaxial, the brush head 23 is arranged at the tail end of the central brush shaft 28, and the nut sleeve 26 is sleeved on the main rotating shaft 21 and can move back and forth along the axial direction of the main rotating shaft 21 within the length region range of the thread 27; the sleeve 24 is sleeved on the central brush shaft 28 and can slide back and forth along the axis direction of the central brush shaft 28, one end of the telescopic rod 22 is hinged to the sleeve 24, the other end of the telescopic rod is provided with the brush head 23, one end of the extension spring 25 is connected to the middle part of the telescopic rod 22, and the other end of the extension spring is connected to the main rotating shaft 21. Preferably, the brush head 23 may be made of sponge. Further preferably, three telescopic rods 22 are provided, and the three telescopic rods 22 are rotationally symmetrical with the central brush shaft 28 as an axis.

According to the invention, the brush head 23 on one of the central brush shafts 28 is fixedly connected or hinged with the central brush shaft 28, and the brush head 23 is hinged with the telescopic rod 22.

The contraction and expansion movement of the telescopic shaft 22 is performed such that the hydraulic cylinder 15 starts to move after water having a certain water pressure is supplied, and then the main rotating shaft 21 starts to rotate. The nut sleeve 26 will move along its axial direction with the rotation of the main shaft 21, and when it moves to the left, it will spread the telescopic rod 22 to increase the brushing radius. Conversely, the telescopic rod 22 is moved closer to the central brush axis 28, and the brush radius is reduced. The whole pot surface can be cleaned by the circulation.

The rotation of the telescopic rod 22 is achieved in that the rack 16 moves to rotate the main shaft 21, and the nut sleeve 26 can move back and forth along the axial direction of the main shaft 21 due to the threaded connection of the nut sleeve 26 with the thread 27 area on the main shaft 21.

In order to make the hydrodynamic force pot brushing machine more stable in work, the supporting component is provided with a base which is of a sucker structure and consists of a plurality of small suckers. This configuration is more stable than a single large suction cup.

During the use, as shown in fig. 6, buckle 5 fixes pot 4 on the wall of the water tank with certain angle to this can make the water that flows into in pot 4 flow out by oneself, has avoided water to persist in pot 4, splashes everywhere in the in-process of brushing.
