Description

[Technical Field]

[0001] FIELD OF THE INVENTION The present invention relates to cleaning tools, and more particularly to hydraulic rotary cleaning brushes. [Background technology]

[0002] Many people use brushes, which accelerate cleaning while showering due to the friction of the brush and the increased contact area, and also brush away dead skin and secretions, thereby saving a certain amount of labor and time. However, the back-and-forth motion required is time-consuming and tiring, and brushing the back in particular can be difficult. Most people use towels to dry their backs during the shower, and even towel exercises have been developed, but they are inconvenient and time-consuming, so they have not become widespread.

[0003] In light of this, some manufacturers have developed brushes that use a rotating motor to rotate the brush head to accelerate cleaning, but the drawbacks of this are that adding a battery to the motor makes it quite heavy, and it must be constantly charged. In addition, the motor parts can be damaged if they are exposed to water or water vapor. Furthermore, the strong motor torque after deceleration causes the rotating brush head to slide due to the reaction force, making operation unstable.

[0004] Although the above method can save time and effort, the water pours down from the shower head, spreading over a large area and not concentrating on the area to be brushed. The brush head or towel further impedes the flow of water, and the brush can only be done with the water that hits the higher parts of the body and runs down. This concentrates the cleansing power and makes it impossible to wash away the remaining bath salts, and it is not possible to quickly remove the scrubbed secretions and dead skin. Repeated washing ends up wasting more water resources.

[0005] Some manufacturers have also developed brushes that use water to rotate the brush head without using a motor, but as the water rotates the brush head, it loses energy, the water pressure is insufficient, and the water column is weak and difficult to wash away dirt.However, the brush may not have enough rotational force to maintain a certain amount of water pressure, and when it hits the object being cleaned, it cannot rotate, so the amount of water must be increased, which leads to a waste of water resources.

[0006] To increase torque, a method can be used in which the flow of water drives a combination of an Archimedes screw and a bevel gear set, but this method has an insufficient reduction ratio and the rotation speed of the brush is too high, which makes the user feel uncomfortable when used for brushing the user's body, and the volume of the Archimedes screw is too large, so the rotation speed cannot be further reduced by installing multiple sets.

[0007] In light of this, finding new solutions has clearly become an urgent challenge for the industry. [Prior art documents] [Patent documents]

The partition plate 12 protrudes toward the first space 111 and forms a central bearing portion 122.

[0030] As shown in Figures 2, 8, and 9, the sealing lid of the top cover 13 is provided at the top opening 113, and in this embodiment, the top cover 13 protrudes toward the partition plate 12 to form a top bearing portion 131, but this is not limited to this.

[0031] 2 and 10 to 12, the bottom cover 14 is connected to the ring wall 11, a sealed cover is provided at the bottom opening 114, the bottom cover 14 is recessed away from one surface of the partition plate 12 toward the second space 112 to form an installation groove 141, and a plurality of drainage holes 142 are formed through the bottom cover 14, and each drainage hole 142 communicates with the second space 112. In this embodiment, the bottom cover 14 protrudes toward one surface of the partition plate 12 to form a bottom bearing portion 143, and the reduction mechanism 40 is rotatably mounted on the bottom bearing portion 143, but this is not limiting.

[0032] As shown in FIGS. 2 and 13 to 16 , in this embodiment, the bottom cover 14 is provided with a seal brush member 15 having a packing 151 and multiple rod-shaped portions 152. The packing 151 is hermetically installed between the bottom cover 14 and the annular wall 11, and one end of each rod-shaped portion 152 is connected to the packing 151. The multiple rod-shaped portions 152 are installed at intervals from one another, so that the multiple rod-shaped portions 152 together form a brush. Each rod-shaped portion 152 penetrates the bottom cover 14, and the other end of each rod-shaped portion 152 extends in a direction away from the second space 112. The seal brush member 15 can be made of a silica gel material and seals the gap between the bottom cover 14 and the annular wall 11, but this is not limiting, and the seal brush member 15 may be omitted.

[0033] As shown in Figures 1 and 2, the ring wall 11 may further have an installation section 116 that protrudes from the outer wall surface of the ring wall 11 and surrounds the water inlet hole 115, thereby forming an installation space 1161 inside the installation section 116 and connecting the installation space 1161 and the water inlet hole 115, but this is not limited to this and in other embodiments the installation section 116 may not be provided.

[0034] The handle 20 is connected to the main body 10, and in this embodiment, the handle 20 is a tubular body with a passage 21 formed therethrough in the longitudinal direction. The handle 20 is closely attached to the installation portion 116 of the annular wall 11, and the passage 21 of the handle 20 is interconnected with the water inlet hole 115 via the installation space 1161, but this is not limiting, and the handle 20 does not have to be tubular.

[0035] As shown in Figures 1 to 3 and 17 to 19, the water wheel 30 is rotatably mounted in the first space 111. Specifically, the water wheel 30 includes a runner 31 and a plurality of blades 32. Opposing sides of the runner 31 are respectively mounted on the central bearing portion 122 of the partition plate 12 and the top bearing portion 131 of the upper cover 13, thereby restricting the position of the runner 31 to prevent misalignment. The runner 31 is rotatable around a rotation axis M, has an outer peripheral surface 311 surrounding the rotation axis M, and a plurality of blades 32 are connected to the outer peripheral surface 311, with each blade 32 inclined with respect to the rotation axis M, so that the water flow entering from the water inlet hole 115 is guided to the partition plate 12 when rotating the blades 32, but is not limited to this.

[0036] 1 and 2, the reduction mechanism 40 is rotatably installed in the second space 112, and the reduction mechanism 40 passes through the partition plate 12 and is connected to the water wheel 30, so that the water wheel 30 drives and rotates the reduction mechanism 40. In the first embodiment, the reduction mechanism 40 is a cycloid pinwheel reduction mechanism 40, and may include an eccentric crank 41, a plurality of needle teeth 42, two cycloid gears 43, and a driven rotor 44.

[0037] As shown in Figures 2 and 21 to 23, the eccentric crank 41 has a connection part 411 and two eccentric disks 412. The connection part 411 is an axial lever that passes through the partition plate 12 and is connected to the runner 31 of the water turbine 30, thereby allowing the water turbine 30 to rotate and drive the eccentric crank 41. Both eccentric disks 412 are provided eccentrically to the connection part 411. In this embodiment, the eccentric disks 412 are disk-shaped, and the connection part 411 eccentrically connects both eccentric disks 412 in the axial direction. Specifically, as shown in Figures 21 and 23, both eccentric disks 412 are provided symmetrically with respect to the connection part 411, but this is not limiting. In other embodiments, only one eccentric disk 412 may be provided.

[0038] 2 and 6, the needle teeth 42 are located in the second space 112, and one end of each needle tooth 42 is connected to the partition plate 12 and the other end extends toward the bottom opening 114. The needle teeth 42 surround the eccentric crank 41, and the needle teeth 42 are spaced apart.

[0039] As shown in Figures 1, 2, 4, and 20, the two cycloid gears 43 are mounted on the eccentric disk 412 and positioned between the needle teeth 42. The periphery of each cycloid gear 43 is recessed to form a plurality of cycloid grooves 431, and the periphery of the cycloid gear 43 where the cycloid grooves 431 are located is formed in a hypotrochoidal shape. The cycloid gear 43 is recessed toward one side of the bottom opening 114 to form a plurality of drive grooves 432. The eccentric crank 41 can rotate the cycloid gear 43, and as the cycloid gear 43 rotates, the periphery of the cycloid gear 43 selectively contacts each of the needle teeth 42. In this embodiment, the number of cycloid grooves 431 is nine and the number of needle teeth 42 is ten, thereby achieving a reduction ratio of 9:1, but this is not limited thereto.

[0040] 1, 2, and 4, the driven rotor 44 connects the cycloid gear 43 and the rotary brush head 50, whereby the cycloid gear 43 rotates and drives the rotary brush head 50. As shown in FIGS. 24 to 26, the driven rotor 44 has a plurality of drive rods 441 and an output shaft 442. The drive rods 441 are respectively inserted through the transmission grooves 432 of the cycloid gear 43, and one end of the output shaft 442 is connected to the drive rods 441. In this embodiment, the driven rotor 44 is rotatably mounted relative to the bottom bearing portion 143 of the bottom cover 14 to prevent misalignment.

[0041] As shown in Figures 1, 2, and 27 to 29, the rotary brush head 50 is rotatably installed in the installation groove 141, and the rotary brush head 50 is connected to the reduction mechanism 40. In this embodiment, the rotary brush head 50 has a rotating disk 51 and a plurality of brush bristles 52. The rotating disk 51 has two opposing disk surfaces, and one disk surface of the rotating disk 51 is connected to the driven rotor 44 of the reduction mechanism 40, specifically, connected to the other end of the output shaft 442 relative to the pair of drive rods 441. One end of each brush bristles 52 is connected to the disk surface at the other end of the rotating disk 51, and the other end of each brush bristles 52 extends in a direction away from the second space 112. In this embodiment, as shown in Figure 27, multiple brush bristles 52 are arranged in a cross shape on the rotating disk portion 51, but as shown in Figure 30, multiple brush bristles 52A of the rotating brush head 50A may also be arranged in multiple spiral lines extending outward from the center of the rotating disk portion 51A, but are not limited to these two arrangement patterns.

[0042] When applying the present invention, the handle 20 can be connected to a water pipe. Water flows along the passage 21 in the handle 20 and enters the first space 111 of the main body 10 through the water inlet hole 115, striking the blades 32 of the water wheel 30 and causing it to rotate. The inclined blades 32 of the water wheel 30 guide the water to the partition plate 12, then through the communication holes 121 in the partition plate 12 into the second space 112, and finally through the drain hole 142 on the bottom cover 14. When the water wheel 30 rotates, the reduction mechanism 40 is rotated, which in turn rotates the rotary brush head 50. The reduction principle of the cycloid pinwheel increases the rotational torque of the rotary brush head 50.

[0043] In the first embodiment, the present invention directly installs the needle teeth 42 on the partition plate 12, eliminating the need for a separate, fixed pinwheel as in the conventional cycloid pinwheel mechanism, thereby reducing the volume and realizing a structure in which the cycloid pinwheel mechanism is applied to the hydraulic rotary cleaning brush.It also makes the device lighter, making it easier for users to hold in their hands.

[0044] Next, as shown in FIGS. 31 and 32, a second embodiment of the present invention is almost the same as the first embodiment, except that a reduction mechanism 40B in this embodiment uses a harmonic reduction mechanism.

[0045] Specifically, in this embodiment, the internal tooth groove 123B is recessed into the surface of the partition plate 12B facing the second space 112, and the internal tooth groove 123B and the second space 112 are in communication with each other. Meanwhile, the reduction gear mechanism 40B includes an internal tooth portion 45B, a wave generator 46B, a flexible gear 47B, and a driven rotor 44B. The internal tooth portion 45B protrudes inward in the radial direction of the internal tooth groove 123B and is provided on the inner annular wall surface of the internal tooth groove 123B. The wave generator 46B is rotatably provided in the internal tooth groove 123B. The wave generator 46B penetrates the partition plate 12B and is connected to the water turbine 30, thereby enabling the wave generator 46B to be rotationally driven.

[0046] The flexible gear 47B is disposed in the internal tooth groove 123B and meshes with the internal tooth portion 45B, and the wave generator 46B is located radially inside the flexible gear 47B. The flexible gear 47B can elastically deform in the radial direction, and when the wave generator 46B rotates, the flexible gear 47B can simultaneously elastically deform. Specifically, the flexible gear 47B deforms into a substantially elliptical shape, which causes the flexible gear 47B to mesh with different portions of the internal tooth portion 45B, thereby performing forward movement. The driven rotor 44B connects the flexible gear 47B to the rotary brush head, which causes the flexible gear 47B to rotate the rotary brush head.

[0047] In the second embodiment, the present invention directly forms an internal tooth groove 123B on the partition plate 12B, eliminating the need for a fixed internal gear as in the conventional harmonic reduction mechanism, further reducing the volume, realizing the combination of the harmonic reduction mechanism and the hydraulic rotary cleaning brush, which also reduces the weight and makes it easier to hold.

[0048] When using a water heater, the power of the water heater varies from family to family, and the pipe diameter of a low-power water heater is small, resulting in low water pressure. However, the present invention requires sufficient water pressure to operate. Otherwise, even if the rotating brush head 50 can rotate, it may stop rotating due to increased friction when it comes into contact with an external object, causing inconvenience to the user or causing the user to mistakenly believe it is malfunctioning. In this case, the third embodiment of the present invention can be applied.

[0049] 33 to 36, the third embodiment of the present invention is substantially similar to the first embodiment, but differs mainly in that the third embodiment further comprises a pressure valve 60C that is provided in installation space 1161 within installation section 116 and communicates with water inlet hole 115. In this embodiment, pressure valve 60C is located between water inlet hole 115 and handle 20, and passage 21 of handle 20 and water inlet hole 115 communicate with pressure valve 60C.

[0050] Specifically, the pressure valve 60C includes a valve body 61C, a valve passage 62C, a closing member 63C, and an elastic member 64C. In this embodiment, the valve body 61C is a silica gel column whose outer periphery is in close contact with the inner periphery of the mounting portion 116. The valve passage 62C penetrates opposite ends of the valve body 61C to form a valve inlet 621C and a valve outlet 622C. The valve passage 62C communicates with the water inlet 115. The valve body 61C protrudes inward at the valve outlet 622C to form a flange 623C. The closing member 63C is disposed within the valve passage 62C and selectively closes the valve inlet 621C. The elastic member 64C is disposed within the valve passage 62C and is extendable and retractable along the valve passage 62C. One end of the elastic member 64C is connected to the closing member 63C, and the other end of the elastic member 64C is fixed to a flange 623C of the valve body 61C. In this embodiment, the elastic member 64C is a tower-type compression spring having one end tapered relative to the other end, and a spherical closing member 63C connected to the narrow end of the elastic member 64C. The elastic member 64C tends to push the closing member 63C toward the valve inlet 621C to block the valve inlet 621C. However, the pressure valve 60C is not limited to this configuration, and other types of pressure valves can be selected according to actual needs.

[0051] In the third embodiment of the present invention, when water flows into valve inlet 621C, it is blocked by closing member 63C. If the water pressure is sufficient to push compressible elastic member 64C of closing member 63C, valve inlet 621C is not blocked, allowing water to flow into valve passage 62C. Conversely, if the water pressure is insufficient, closing member 63C continues to close valve inlet 621C, preventing water from entering water inlet 115 through pressure valve 60C. By installing pressure valve 60C and using elastic member 64C with a specific elastic modulus, it is possible to check whether the water pressure of the water flow is sufficient to rotate rotary brush head 50 of the present invention. This prevents the rotary brush head 50 from becoming unable to rotate due to insufficient water pressure, or the rotary brush head 50 from stopping rotation when it comes into contact with an external object, which may lead the user to believe the present invention is malfunctioning. This also allows the user to detect and adjust the water pressure to ensure smooth operation of the present invention. However, the present invention can be used without pressure valve 60C.

[0052] As described above, the present invention uses the water wheel 30 to hydraulically drive the rotary brush head 50. Normal tap water pressure can be converted into rotational energy for the rotary brush head 50 using the water wheel 30, eliminating the need for a separate rotating electric motor, reducing weight, and reducing the risk of malfunctions and electrical leakage. The addition of the speed reduction mechanism 40 increases the torque of the rotary brush head 50, preventing it from stopping rotation due to friction, consuming less water energy, maintaining the water pressure to produce a weak, steady water column, and reducing the amount of water required to rotate the rotary brush head 50, thereby reducing waste. The present invention employs a plastic water wheel 30 and speed reduction mechanism 40, which are slightly heavier than typical shower heads. Furthermore, the speed reduction mechanism 40 of the present invention is simpler and easier to assemble than a rotating electric motor or a combination of an Archimedes screw and a bevel gear set.

[0053] According to the present invention, rinsing can be combined with the rotation of the rotary brush head 50, allowing rinsing and brushing to be completed simultaneously, saving water, time, and effort. In addition to the rotary brush head 50, a brush consisting of the rod portion 152 of the seal brush member 15 can also be used for brushing the area to be brushed, and the static rod portion 152 and the dynamic rotary brush head 50 can be used together to brush more thoroughly. The present invention can also be used for washing faces, washing dishes, washing fruits and vegetables, washing cars, or cleaning floors, and can complete rinsing and brushing simultaneously, and is not limited to bathing applications.
