[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] Please refer to Figures 1 to 8 A water outlet device with adjustable water outlet swing amplitude according to an embodiment of the present invention comprises a housing 10, a water outlet member 20, an impeller 30 and an amplitude modulation mechanism, etc. The water outlet device of the present invention can be various water outlet devices such as a shower, a faucet or a spray gun.

[0049] The housing 10 of the water outlet device has a receiving chamber 11 and a water inlet channel 12 connected to the receiving chamber 11; the water outlet 20 has a water outlet 21 connected to the receiving chamber 11, and the water outlet 20 is swingably arranged on the housing 10, and the water flow of the water inlet channel 12 flows out from the water outlet 21 of the water outlet 20 after passing through the receiving chamber 11. The impeller 30 is arranged in the receiving chamber 11 and cooperates with the water outlet 20. The impeller 30 rotates under the water flow pressure of the water inlet channel 12 to drive the water outlet 20 to swing; the amplitude modulation mechanism is installed on the housing 10 and is used to adjust the swing amplitude of the water outlet 20.

[0050] By setting up an amplitude modulation mechanism and utilizing the amplitude modulation mechanism to adjust the swing amplitude of the water outlet part 20, the swing amplitude of the water outlet flow can be adjusted, thereby improving the user experience of the product, increasing the added value of the product, and filling the gap that the water outlet flow of the water outlet device on the market cannot adjust the swing amplitude.

[0051] The water outlet device of this embodiment also includes a connecting member 50 and an eccentric shaft 40. The eccentric shaft 40 is eccentrically fixed on the impeller 30. The impeller 30 rotates around the rotating shaft 31 fixedly arranged in the accommodating chamber 11 and drives the eccentric shaft 40. The first end of the connecting member 50 cooperates with the eccentric shaft 40, and the second end of the connecting member 50 cooperates with the water outlet member 20. When the eccentric shaft 40 rotates with the impeller 30, the water outlet member 20 is driven to swing through the connecting member 50. The impeller 30 drives the water outlet member 20 to swing through the eccentric shaft 40 and the connecting member 50, and the structure is simple and reliable.

[0052] In the water outlet device of this embodiment, a support point is formed between the water outlet member 20 and the housing 10, and the water outlet member 20 swings back and forth around the support point. The amplitude modulation mechanism adjusts the length of the driving force arm driving the water outlet member 20 by adjusting the matching position between the second end of the connecting member 50 and the water outlet member 20, thereby adjusting the swing amplitude of the water outlet member 20. The design is ingenious, the structure is simple, and the adjustment is convenient.

[0053] In the water outlet device of this embodiment, the water outlet member 20 is provided with a linkage part 22, the second end of the connecting member 50 is movably connected to the linkage part 22, a slide groove 23 is provided on the linkage part 22, the second end of the connecting member 50 is a circular shaft, and the position of the circular shaft in the slide groove 23 is the connection position, and the amplitude modulation mechanism adjusts the length of the driving force arm that drives the water outlet member 20 by adjusting the position of the second end of the connecting member 50 in the slide groove 23, so as to adjust the length of the driving force arm that drives the water outlet member 20, and the structure is simple and compact.

[0054] In the water outlet device of this embodiment, the eccentric shaft 40 is eccentrically fixed on the impeller 30, and the eccentric shaft 40 extends axially along the rotation axis of the impeller 30. Specifically, the eccentric shaft 40 is fixedly connected with the impeller 30 in an integrally formed manner, and of course the two can also be formed separately and then fixedly connected together. A waist-shaped hole 51 is provided at the first end of the connecting member 50, and the eccentric shaft 40 is passed through the waist-shaped hole 51. The connecting member 50 is movably connected to the eccentric shaft 40 through the waist-shaped hole 51, and the transmission structure is simple, reliable and stable.

[0055] In the water outlet device of this embodiment, the amplitude modulation mechanism includes a driving member 61 and a limiting member 62. The driving member 61 can be rotatably limited on the housing 10. The driving member 61 is threadedly connected to the limiting member 62. The connecting member 50 and the limiting member 62 are limited in the movable direction of the limiting member 62. When the driving member 61 is rotated, the limiting member 62 is displaced relative to the driving member 61, and the limiting member 62 then drives the connecting member 50 to be displaced relative to the water outlet. The position of the connecting member 50 is adjusted by adjusting the position of the limiting member 62. Of course, in other embodiments, the position of the connecting member 50 can also be adjusted directly, or the driving member 61 and the limiting member 62 are not connected by threads but are replaced by a snap connection with multiple adjustment gears.

[0056] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 Specifically, the connecting member 50 is a plate-like structure, and the limiting member 62 also includes a limiting groove 621. The connecting member 50 can be slidably inserted into the limiting groove 621, and the two ends of the connecting member 50 respectively extend out of the limiting groove 621. Through the limiting groove 621, the connecting member 50 and the limiting member 62 are limitedly matched in the movable direction of the limiting member 62.

[0057] In the water outlet device of this embodiment, the driving member 61 includes a knob portion 611 and a first threaded portion 612 connected to each other. The knob portion 611 is located outside the accommodating chamber 11, so that the knob portion 611 can be directly driven. Of course, in other embodiments, the driving member 61 can also be completely arranged in the accommodating chamber 11. The first threaded portion 612 is located inside the accommodating chamber 11. The second threaded portion 622 provided on the limiting member 62 is threadedly connected with the first threaded portion 612. A clamping groove 613 is provided between the knob portion 611 and the first threaded portion 612. A clamping ring 63 that is clamped and matched with the clamping groove 613 is also included. The clamping ring 63 enables the driving member 61 to be limited and matched with the housing 10. The driving member 61 is limited on the housing 10 by the clamping and matching of the clamping ring 63 and the clamping groove. The structure is simple and the installation between the driving member 61 and the housing 10 is easy.

[0058] Please refer to Figure 4 , Figure 5 , Figure 7 and Figure 8 In the water outlet device of this embodiment, the water outlet member 20 includes a spherical portion, and the housing 10 is provided with a spherical groove 13 that matches the spherical portion 23. The spherical portion 23 rotates in the spherical groove 13. The water outlet member 20 is rotatably attached to the housing 10 through the spherical portion, and the swinging movement of the water outlet member 20 is smoother, more stable, and more reliable.

[0059] When water enters the water inlet channel 12, the water flow of the water inlet channel 12 drives the impeller 30 to rotate, flows to the water outlet 20 through the accommodating chamber 11, and flows out from the water outlet 21. The impeller 30 drives the eccentric shaft 40 to move, and the eccentric shaft 40 further drives the water outlet 20 through the connecting member 50. Since the eccentric shaft 40 moves back and forth between approaching the water outlet 20 and away from the water outlet 20 when following the movement of the impeller 30, the connecting member 50 slides back and forth under the drive of the eccentric shaft 40, and then drives the water outlet 20 to swing back and forth, thereby achieving the swing effect of the water flow.

[0060] Please refer to Figure 7 When the swing amplitude of the water outlet needs to be adjusted to a larger value, the driving member 61 is rotated to make the limit member 62 move downward relative to the driving member 61, and the limit member 62 drives the connecting member 50 to move downward, so that the position of the second end of the connecting member 50 in the slide groove 23 moves downward, that is, the driving force arm of the water outlet member 20 is shorter, so that the swing amplitude α of the water outlet can be adjusted to a larger value, and the angle range of the swing amplitude is α at this time.

[0061] Please refer to Figure 8 When the swing amplitude of the water flow needs to be adjusted to a smaller value, the driving member 61 is rotated to make the limit member 62 move upward relative to the driving member 61, and the limit member 62 drives the connecting member 50 to move upward, so that the second end of the connecting member 50 moves upward in the slide groove 23, that is, the driving force arm of the water outlet member 20 is longer, so that the swing amplitude of the water flow can be adjusted to a smaller value. At this time, the angle range of the swing amplitude is β, α>β.

[0062] In other embodiments, the water outlet device may further include a gear set reduction mechanism, the impeller 30 is linked to the water outlet member through the gear set reduction mechanism, and the eccentric shaft 40 is linked to the final gear of the gear set reduction mechanism. By providing a gear set reduction mechanism, the water outlet swing frequency of the water outlet device is reduced, which can further improve the user experience of the product.

[0063] In other embodiments, the eccentric shaft 40 may also be replaced by an eccentric wheel (not shown), and a return spring may be added, so that the connecting member 50 moves back and forth under the action of the eccentric wheel and the return spring, thereby controlling the reciprocating swing of the water outlet member 20.

[0064] It can be understood that the amplitude modulation mechanism of the present invention is not limited to the above preferred embodiments, as long as the amplitude modulation mechanism can adjust the swing amplitude of the water outlet member 20.

[0065] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
