Description

[0001] This application is a divisional application of application number 201810032292.5, filed on January 12, 2018, entitled "A novel transmission mechanism and an inlet valve and water tank fitting having the same," the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to a novel transmission mechanism and an inlet valve and water tank fittings having the same. Background Technology

[0003] Traditional gear meshing transmission methods generally employ transmission structures such as gear-to-gear, gear-to-chain, and gear-to-pulley. However, on the one hand, gear-to-gear transmission has disadvantages: it occupies a large space, and when the distance between the driving and driven gears is large, several intermediate gears are needed to assist in the transmission, which also affects transmission efficiency when there are many intermediate gears. On the other hand, gear-to-chain and gear-to-pulley transmissions have disadvantages: chains and pulleys can only transmit power on a plane.

[0004] Due to the limited space in toilet tanks, a larger tank component footprint results in a correspondingly smaller water storage capacity. Traditional gear-driven transmission methods significantly impact the structural layout of tank components and the utilization rate of tank space. Summary of the Invention

[0005] To solve the above problems, the present invention provides a novel transmission mechanism and inlet valve and water tank accessories having the same, which has a simple and compact structure and a more flexible spatial layout.

[0006] One of the objectives of this invention is to provide a novel transmission structure, including a driving member (10) and a driven member (20), and further including a plurality of balls (30) disposed between the driving member (10) and the driven member (20), the balls (30) being arranged on a preset track (31); wherein, the driving member (10) is provided with a driving tooth groove (11) that meshes and drives with the balls (30), and the driven member (20) is provided with a driven tooth groove (21) that meshes and drives with the balls (30); the driving member (10) moves and drives the balls (30) to move along the preset track (31) through the driving tooth groove (11), and then drives the driven member (20) to move through the driven tooth groove (21).

[0007] Preferably, the preset track (31) is a planar track or a three-dimensional track.

[0008] Preferably, the active member (10) rotates and drives the ball (30) to circulate along the preset track (31) through the active tooth groove (11), and then drives the driven member (20) to rotate through the driven tooth groove (21).

[0009] Preferably, the active tooth groove (11) and the driven tooth groove (21) are arc-shaped grooves that match the size and curvature of the ball (30).

[0010] Preferably, the preset track (31) is provided with notches (32) corresponding to the positions of the driving member (10) and the driven member (20), and the driving tooth groove (11) and the driven tooth groove (21) are engaged with the ball (30) through the notches (32).

[0013] Preferably, the water inlet valve includes a water inlet body (53), a water stop cup (51) mounted on the water inlet body (53), and an adjusting rod (52) rotatably mounted on the water stop cup (51). The driven member (20), ball bearing (30), and preset track (31) are arranged at the bottom of the water stop cup (51). The driving member (10) is circumferentially limited to the adjusting rod (52). The water inlet body (53) is provided with a second adjusting tooth (55) arranged longitudinally. The driven member (20) is provided with a first adjusting tooth (22) that is helically engaged with the second adjusting tooth (55). Operating the adjusting rod (52) drives the driving member (10) to rotate. The driven member (20) rotates accordingly and moves up and down along the second adjusting tooth (55) of the water inlet body (53) through the first adjusting tooth (22), thereby realizing the height adjustment of the water stop cup (51).

[0014] The third objective of this invention is to provide a water tank accessory, including a first adjusting member and a second adjusting member. The first adjusting member is sleeved outside the second adjusting member and can move axially relative to the second adjusting member.

Due to the spherical structure of the ball, the driving and driven parts can be embedded and meshed with the ball from any angle, making the structure simple and compact, the spatial layout more flexible, and the application field wider. In particular, when applied to water tank accessories such as inlet valves and drain valves, it can break through the traditional structural limitations. Attached Figure Description

[0036] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0037] First embodiment (the preset track of the transmission structure is a planar track)

[0038] like Figure 1 and Figure 2As shown, a novel transmission structure in this embodiment includes a driving member 10 and a driven member 20, and further includes a plurality of balls 30 disposed between the driving member 10 and the driven member 20, the balls 30 being arranged on a preset track 31; wherein, the driving member 10 is provided with a driving tooth groove 11 that meshes and drives with the balls 30, and the driven member 20 is provided with a driven tooth groove 21 that meshes and drives with the balls 30; the driving member 10 moves and drives the balls 30 to move along the preset track 31 through the driving tooth groove 11, and then drives the driven member 20 to move through the driven tooth groove 21.

[0039] In this embodiment, the driving member 10 and the driven member 20 can be toothed components such as gears or racks. In this embodiment, the driving member 10 and the driven member 20 are gears. The driving member 10 rotates and drives the ball 30 to circulate along the preset track 31 through the driving tooth groove 11, and then drives the driven member 20 to rotate through the driven tooth groove 21.

[0040] In this embodiment, the driving member 10, the driven member 20, the ball bearing 30, and the preset track 31 are all disposed within a base 40; it also includes a driving handle 41 for driving the driving member 10 and a driven shaft 42 for outputting the motion of the driven member 20. The driving handle 41 is connected to the driving member 10 and one end extends out of the base 40 for operation. Operating the driving handle 41 causes the driving member 10 to rotate, thereby driving the driven member 20 and outputting motion through the driven shaft 42.

[0041] In this embodiment, the predetermined track 31 is a planar track with a racetrack-shaped structure. Multiple balls 30 are arranged sequentially on the predetermined track 31. Preferably, the predetermined track 31 has notches 32 corresponding to the positions of the driving member 10 and the driven member 20, respectively. The driving tooth groove 11 and the driven tooth groove 21 engage with the balls 30 through the notches 32. Specifically, the driving tooth groove 11 is arranged around the outer circumferential surface of the driving member 10, and the driven tooth groove 21 is arranged around the outer circumferential surface of the driven member 20. Furthermore, since the balls 30 are spherical, the driving tooth groove 11 and the driven tooth groove 21 preferably adopt arc-shaped grooves that match the size and curvature of the balls 30; that is, the inner diameter of the arc-shaped groove matches the outer diameter of the balls 30.

[0042] Second embodiment (output angle of transmission structure is variable)

[0043] like Figure 3 and Figure 4As shown, the main difference between this embodiment and the first embodiment is that in this embodiment, the preset track 31 is a three-dimensional track, the active tooth groove 11 is arranged around the outer peripheral surface of the active member 10, and the driven tooth groove 21 is arranged around the outer peripheral surface of the driven member 20; since the ball is spherical, the output angle of the mating driven member can vary over a large range. Figure 3 As shown, the output angle of the driven member 20 is the same as the input angle of the driving member 10; as Figure 4 As shown, the driven tooth groove 21 of the driven member 20 can rotate around the ball 30, so that the output angle of the driven member 20 is 90 degrees from the input angle of the driving member 10; due to the use of a three-dimensional track, the output angle of the driven member 20 and the input angle of the driving member 10 are not on the same plane.

[0044] Third embodiment (the driven tooth groove of the transmission structure is an end face tooth groove)

[0045] like Figure 5 and Figure 6 As shown, the main difference between this embodiment and the first embodiment is that in this embodiment, the active tooth groove 11 is arranged around the outer peripheral surface of the active member 10, and the driven tooth groove 21 is arranged around the lower end surface of the driven member 20, which can also realize the change of the output angle of the driven member 20.

[0046] In addition, the active tooth groove 11 can be arranged around the outer peripheral surface, upper end surface, or lower end surface of the active member 10; the driven tooth groove 21 can be arranged around the outer peripheral surface, upper end surface, or lower end surface of the driven member 20. Users can combine and match these according to the actual spatial layout requirements. For example, the active tooth groove 11 on the outer peripheral surface can be matched with the driven tooth groove 21 on the outer peripheral surface, the active tooth groove 11 on the outer peripheral surface can be matched with the driven tooth groove 21 on the upper end surface, the active tooth groove 11 on the lower end surface can be matched with the driven tooth groove 21 on the upper end surface, and so on. This is not a limitation.

[0047] Fourth embodiment (water inlet valve stop cup height adjustment mechanism)

[0048] like Figure 7 and Figure 8 As shown, this embodiment provides a water inlet valve, which is equipped with a novel transmission structure as described in any one of the first, second, and third embodiments above.

[0049] In this embodiment, the water inlet valve includes a water inlet body 53, a water stop cup 51 mounted on the water inlet body 53, and an adjusting rod 52 rotatably mounted on the water stop cup 51. The driven member 20, the ball bearing 30, and the preset track 31 are arranged at the bottom of the water stop cup 51. The driving member 10 is circumferentially limited to the adjusting rod 52. The water inlet body 53 is provided with a second adjusting tooth 55 arranged longitudinally, and the driven member 20 is provided with a first adjusting tooth 22 that is helically engaged with the second adjusting tooth 55. By operating the adjusting rod 52, the driving member 10 is rotated, and the driven member 20 rotates accordingly and moves up and down along the second adjusting tooth 55 of the water inlet body 53 through the first adjusting tooth 22, thereby realizing the height adjustment of the water stop cup 51.

[0050] In this embodiment, the active tooth groove 11 is arranged around the outer peripheral surface of the active member 10, the driven tooth groove 21 is arranged around the lower end surface of the driven member 20, and the first adjusting tooth 22 is a helical tooth and is arranged on the outer peripheral surface of the driven member 20.

[0051] Fifth Embodiment (Water Tank Accessory Telescopic Length Adjustment Mechanism)

[0052] like Figures 9 to 11 As shown, this embodiment provides a water tank accessory, including a first adjusting member and a second adjusting member. The first adjusting member is sleeved outside the second adjusting member and can move axially relative to the second adjusting member. It also includes a novel transmission structure as described in any one of the first, second, and third embodiments. The novel transmission structure is disposed on the first adjusting member for adjusting the telescopic length between the first adjusting member and the second adjusting member. The outer wall of the second adjusting member is provided with a second adjusting tooth 55', and the driven member 20 is provided with a first adjusting tooth 22' that is helically engaged with the second adjusting tooth 55'. When the driving member 10 is rotated, the driven member 20 rotates accordingly and moves up and down along the second adjusting tooth 55' of the second adjusting member through the first adjusting tooth 22', thereby realizing the adjustment of the telescopic length of the first adjusting member and the second adjusting member.

[0053] The water tank accessories can be inlet valves or drain valves, etc. In this embodiment, the water tank accessories take the inlet valve as an example. The first adjusting component is the inlet body 53 of the inlet valve, and the second adjusting component is the inlet pipe 54 of the inlet valve. The height of the inlet valve is adjusted by adjusting the telescopic length between the inlet body 53 and the inlet pipe 54 through the novel transmission structure. The driving component 10 is an adjusting cap set on the top of the first adjusting component, and the driving tooth groove 11 is arranged around the lower end face of the driving component 10. The driven component 20 is a collar set at the bottom of the first adjusting component, and the driven tooth groove 21 is arranged around the upper end face of the driven component 20. The first adjusting tooth 22' is a helical tooth and is set on the inner circumferential surface of the driven component 20. The preset track 31 is set on the outer wall of the inlet body 53.
