The whole operation is simple, and multiple brushes can be cleaned at the same time, saving time and effort.

[0004] However, in actual use, it is found that the cleaning method of simply rotating the brush by the motor has the problem of low efficiency. This is because during rotation, the brush pushes the water flow, so that the bristles cannot fully contact the water, resulting in poor cleaning effect, which cannot meet the user's demand for efficient and clean brush cleaning. Therefore, the present application proposes a picture brush cleaning device to solve the above problems. UTILITY MODEL CONTENTS

[0005] In view of the deficiencies of the prior art, the utility model aims to provide a picture brush cleaning device.

This increases the contact area and frequency of the bristles and water, allowing the brush bristles to fully contact the water. This improves the cleaning effect and efficiency, solving the problems raised in the background art.

[0006] The present application specifically adopts the following technical solutions to achieve the above-mentioned purposes:

[0016] 1、By designing the brush rotating assembly and the cleaning assembly, the quality and efficiency of brush cleaning can be greatly improved. When the brush is installed in the multiple conical sleeves, the rotating plate starts to rotate under the driving of the power, and drives the multiple brushes to rotate in the inner rotating cylinder. At the same time, under the driving of the second motor, the inner rotating cylinder and the rotating brush rotate in the opposite direction. The helical guide vanes on the inner wall of the inner rotating cylinder promote the formation of a spiral water flow in the inner rotating cylinder during rotation. This spiral water flow can impact the brush bristles, increasing the contact area and frequency of the bristles and water, so that the brush bristles can be fully contacted with water.

[0017] 2、By designing the through hole, the hexagonal block and the second hexagonal groove, after the cleaning process is completed, the inner rotating cylinder immediately enters a centrifugal rotating state. In this process, the water in the cylinder is discharged outward through the through holes distributed on the cylinder wall under the action of centrifugal force. At the same time, these through holes can filter the impurities such as pigment particles generated during the cleaning of the brush, which are effectively intercepted and remain in the inner rotating cylinder, avoiding the blockage of the drain pipe caused by the overflow of impurities with the water flow. After the drainage process is completed, the second hexagonal groove at the bottom of the inner rotating cylinder will be separated from the hexagonal block at the bottom of the cleaning cylinder. After separation, the user can conveniently take out the inner rotating cylinder from the cleaning cylinder, and then easily pour out the impurities accumulated in it, fully preparing for the next brush cleaning.

[0026] like Figures 1 to 5 As shown: A paintbrush cleaning device includes: a cleaning mechanism 1, including a paintbrush rotating assembly 11, a cleaning assembly 12, and a cleaning cylinder 10 for storing cleaning water. The cleaning assembly 12 includes a rotatable inner rotating cylinder 121. The inner wall of the inner rotating cylinder 121 is provided with a spiral guide vane 122 for rotatably forming a spiral water flow.

A base 13 is installed below the cleaning drum 10, and a second motor 124 is installed inside the base 13. A second hexagonal groove is opened on the lower surface of the inner rotating drum 121, and a hexagonal block 126 is provided in the second hexagonal groove. The output shaft of the second motor 124 is fixedly connected to the hexagonal block 126.

[0028] like Figure 3 As shown: A drain valve 125 is installed on one side of the base 13, and the drain valve 125 is connected to the inside of the cleaning cylinder 10.

[0029] like Figure 1 , Figure 2 , Figure 3 as well as Figure 5As shown: The rotating plate 21 is located above the cleaning cylinder 10, and a set of side blocks 118 are installed around the rotating plate 21. A set of universal balls 119 are installed below each set of side blocks 118. An annular groove 117 is opened on the upper surface of the cleaning cylinder 10, and the rolling part of the universal ball 119 is located in the annular groove 117.

[0030] like Figure 3 As shown: There are multiple sets of conical sleeves 22, and the multiple sets of conical sleeves 22 are installed in a ring at equal intervals. The lower end of the conical sleeve 22 is made of rubber. A set of fixing plates 23 is installed on the upper part of the multiple sets of conical sleeves 22. The fixing plate 23 has an installation hole 24 in the center. The lower end of the conical sleeve 22 is made of rubber, which has good friction, so that the pen barrel is not easy to fall off after installation.

[0031] like Figure 2 As shown: A crossbar 111 is provided above the rotating plate 21, a first motor 112 is installed on the upper surface of the crossbar 111, and a transmission rod 114 is provided below the crossbar 111, and the transmission rod 114 is fixedly connected to the output shaft of the first motor 112.

[0032] like Figure 2 As shown: A hexagonal rod 115 is installed at the lower end of the transmission rod 114. A hexagonal groove 116 is opened in the middle of the upper surface of the rotating plate 21, and the position of the hexagonal groove 116 corresponds to the position of the hexagonal rod 115. When the transmission rod 114 rotates, it can drive the hexagonal rod 115 to rotate in the hexagonal groove 116, thereby driving the rotating plate 21 to rotate.

[0033] like Figure 2 As shown: A set of positioning rods 113 are installed on both sides below the horizontal bar 111. A set of side rods 1110 is provided below the two sets of positioning rods 113. The side rods 1110 are fixedly connected to the cleaning cylinder 10. A docking hole 1111 is opened in the side rod 1110. The positioning rods 113 are inserted into the docking hole 1111 to complete the installation of the paintbrush rotating assembly 11.

[0034] In practical use, the working principle of this utility model is as follows:

[0035] In actual use, first pick up the rotating plate 21 and inject cleaning water into the cleaning cylinder 10. Next, insert the pen barrel through multiple sets of conical sleeves 22 from below the rotating plate 21, so that the upper end of the pen barrel passes through the mounting hole 24. Then, place the rotating plate 21 stably on the cleaning cylinder 10, ensuring that the universal ball 119 accurately falls into the slip ring groove 117. At this time, the brush bristles are immersed in water and located inside the inner rotating cylinder 121. Then pick up the crossbar 111, align the hexagonal rod 115 on the crossbar 111 with the first hexagonal slot 116 and insert it, and insert the positioning rod 113 into the docking hole 1111 to complete the installation of the pen rotating assembly 11. Start the first motor 112 to drive the transmission rod 114 to rotate. The transmission rod 114 drives the rotating plate 21 to rotate through the hexagonal rod 115, and the pen rotates accordingly to begin cleaning. During the rotation of the rotating plate 21, the side block 118 drives the omnidirectional ball 119 to slide smoothly along the path of the annular groove 117. At the same time, the second motor 124 is activated, and the second motor 124 drives the inner rotating cylinder 121 to rotate in the opposite direction to the paintbrush through the hexagonal block 126. When the inner rotating cylinder 121 rotates, the spiral guide vanes 122 inside the cylinder cause the formation of a spiral water flow inside, which impacts the brush bristles rotating in the opposite direction, greatly increasing the contact area and contact frequency between the bristles and the water, allowing the pigment and dirt deep in the bristles to be fully removed, significantly improving the cleaning efficiency.

[0036] After the brushes are cleaned, remove the brush rotating assembly 11 and the rotating plate 21, and take out the cleaned brushes. Next, open the drain valve 125 and simultaneously rotate the inner rotating drum 121. Water in the cleaning drum 10 is discharged through the drain valve 125, and water inside the inner rotating drum 121 is flung out through the through holes 123 on the drum wall. These through holes 123 effectively intercept impurities such as pigment particles generated during cleaning, keeping them inside the inner rotating drum 121 to prevent impurities from overflowing with the water and causing blockage of the drain valve 125 or its connected drain pipe. After the drainage process is complete, lift the inner rotating drum 121 upwards, and the second hexagonal groove at the bottom of the inner rotating drum 121 will smoothly detach from the hexagonal block 126 at the bottom of the cleaning drum 10. After detachment, the user can easily remove the inner rotating drum 121 completely from the cleaning drum 10 and empty the accumulated impurities inside.
