[0001] The present invention relates to the technical field of water outlet devices, and more particularly, to a swinging water outlet device. Background Art

[0002] Water outlet devices are a type of equipment commonly used in daily life, including water outlet devices such as shower heads and ceiling sprays.

[0003] Currently, there are some water outlet devices that can achieve swinging water outlet by relying on water outlet pressure. For example: a patent with the Chinese patent application number CN201510522819.9 and the name of a dynamic water outlet nozzle; another example: a patent with the Chinese patent application number CN201621485442.0 and the name of a shower head swinging water outlet structure. However, in the prior art, some of these water outlet devices have too small a swinging angle of the water outlet, and some have the problem that the water outlet member 9 is easily stuck, resulting in inability to swing. In view of this, the inventor has put forward this application after studying the existing technologies. Summary of the Invention

[0004] The present invention provides a swinging water outlet device, aiming to improve the problems of the existing water outlet devices, such as too small a swinging angle of the water outlet or being easily stuck during swinging.

[0005] To solve the above technical problems, the present invention provides a swinging water outlet device, including:

[0006] A housing mechanism, which includes a body provided with an installation cavity, and the installation cavity is provided with an annular gear portion and a guiding portion;

[0007] A driving mechanism, which includes a driving component, a gear meshed with the gear portion, and a movable member supported by the body and provided with a mating groove and a sliding groove, the sliding groove is adapted to the guiding portion, the driving component is eccentrically connected to the gear, the gear has a pushing portion eccentrically arranged and connected to the mating groove, and the number of teeth of the gear is less than the number of teeth of the gear portion;

[0008] A water outlet mechanism, which includes a water outlet member provided with water outlet holes, and the water outlet member is substantially perpendicular to the guiding portion and rotatably arranged on the body;

[0009] The driving component can drive the gear to rotate according to the incoming water, drive the movable member to move back and forth along the guiding portion, so as to drive the water outlet member to rotate forward and backward.

[0010] As a further optimization, the driving component includes an inclined water member provided with inclined water holes and an impeller, the impeller is eccentrically connected to the gear, and the inclined water member can drive the impeller to rotate.

[0011] As a further optimization, the guiding portion is a strip-shaped protrusion provided on the bottom wall of the installation cavity and protruding upward.

[0012] As a further optimization, the fitting groove is an elliptical groove or a rectangular groove with chamfered corners.

[0013] As a further optimization, the water outlet mechanism includes a connecting member for connecting the movable member and the water outlet member, and the connecting member is provided with a connecting groove; the movable member is provided with a driving section extending outward and inserted into the connecting groove.

[0014] As a further optimization, the number of teeth of the gear is less than that of the gear portion by one tooth.

[0015] As a further optimization, the water outlet member is a columnar geometric body with a water passage therein, and the water outlet member is provided with a plurality of water outlet holes respectively communicating with the water passage and arranged in a straight line.

[0016] As a further optimization, the diameter of the driving section is smaller than that of the connecting groove.

[0017] As a further optimization, the pushing portion is a protrusion eccentrically provided on the gear and extending outward.

[0018] As a further optimization, the housing mechanism includes an upper cover disposed on the body, the upper cover is provided with a water inlet communicating with the installation cavity, and the inclined water member and the upper cover are of an integral structure.

[0019] By adopting the above technical solutions, the following technical effects can be achieved by the present invention:

[0020] 1. The water outlet device of the present invention can utilize the pressure of the inlet water to achieve reliable water outlet and large-amplitude swing. Specifically, the driving assembly eccentrically drives the gear to mesh with the gear portion to rotate at a reduced speed, and the gear drives the movable member to move relative to the guiding portion through the pushing portion. Since the guiding portion restricts the moving direction of the movable member, the gear can reliably push the movable member to move back and forth relative to the guiding portion. The movable member moving back and forth can drive the water outlet member to rotate forward and backward, thereby realizing the forward and backward swing of the water outlet.

[0021] 2. In the present invention, the fitting groove is an elliptical groove or a rectangular groove with chamfered corners. Therefore, during the process of the pushing portion driving the movable member to move through the fitting groove, since the pushing portion can move unobstructed in the length direction of the fitting groove, the movable member will not move significantly left and right. And since the pushing portion cannot move unobstructed in the width direction of the fitting groove, the movable member will be forced to move in the front and back directions, thereby realizing the forward and backward rotation of the water outlet member.

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0037] As Figures 1 to 5 shown, this embodiment provides a swinging water outlet device, comprising: a housing mechanism 1, a driving mechanism, and a water outlet mechanism. Specifically:

[0038] As Figure 3 and Figure 4 shown, the housing mechanism 1 includes an upper cover 2 and a body 7 provided with an installation cavity 11. The installation cavity 11 is provided with an annular gear portion 12 and a guiding portion 14, and the upper cover 2 is provided with a water inlet communicating with the installation cavity 11. Among them, the installation cavity 11 is generally a circular groove provided in the body 7, the gear portion 12 is a gear 5 annularly provided on the side wall of the installation cavity 11, the guiding portion 14 is a strip-shaped protrusion provided on the bottom wall of the installation cavity 11 and protruding upward, and the upper cover 2 is connected to the body 7 by screws.

[0039] As Figure 2 , Figure 3 , Figure 5 and Figure 7 shown, the driving mechanism includes a driving component, a gear 5 meshing with the gear portion 12, and a moving member 6 supported on the body 7 and provided with a fitting groove 17 and a sliding groove 18. The sliding groove 18 is adapted to the guiding portion 14, the gear 5 has a pushing portion 16 eccentrically provided and connected to the fitting groove 17, and the gear 5 has one less tooth than the gear portion 12.

[0040] Among them, the bracket driving assembly includes an inclined water member 3 provided with inclined water holes 10 and an impeller 4. The impeller 4 is eccentrically connected to a gear 5. The inclined water holes 10 are through holes obliquely provided in the inclined water member 3. When the water from the outside passes through the inclined water holes 10 through the water inlet, a water flow that is obliquely ejected onto the impeller 4 will be generated, thereby driving the impeller 4 to rotate. The rotating impeller 4 will drive the gear 5 to rotate. Since the gear 5 is internally meshed with the gear portion 12 and the number of teeth of the gear 5 is one less than that of the gear portion 12, the impeller 4 can drive the gear 5 to perform a deceleration motion. In addition, it should be noted that in this embodiment, the inclined water member 3 and the upper cover 2 are of a split structure, while in another embodiment, the inclined water member 3 and the upper cover 2 are of an integral structure.

[0041] Among them, the pushing portion 16 is a cylindrical protrusion eccentrically provided on the gear 5. In addition, the gear 5 is also provided with a water passing hole 15 for water to pass through.

[0042] Among them, a mating groove 17 is provided on the upper surface of the movable member 6, and a sliding groove 18 is provided at the bottom. Specifically, the mating groove 17 is a rectangular groove with rounded corners at the four corners, and the sliding groove 18 is a gap clamped by a pair of ribs. The pushing portion 16 of the gear 5 extends into the mating groove 17, and the pushing portion 16 moves along the side wall of the mating groove 17. In another embodiment, the sliding groove 18 can be a groove provided at the bottom of the movable member 6, and the mating groove 17 can be an elliptical groove, which will not be elaborated here.

[0043] As shown by Figure 2 and Figure 3 the water outlet mechanism includes a water outlet member 9 provided with water outlet holes 13 and a connecting member 8 for connecting the movable member 6 and the water outlet member 9. The movable member 6 can drive the water outlet member 9 to rotate forward and backward through the connecting member 8. The water outlet member 9 is substantially perpendicular to the guiding portion 14 and is rotatably arranged on the main body 7. Among them, the water outlet member 9 is a columnar geometric body with a water passing channel inside. The water outlet member 9 is provided with a plurality of water outlet holes 13 that are respectively connected to the water passing channel and arranged in a straight line. Of course, in another embodiment, the water outlet holes 13 can be of other shapes and arrangements, which will not be elaborated here.

[0044] In the specific operation of the swing water outlet device of this case, the rotating impeller 4 can drive the movable member 6 to swing back and forth through the pushing portion 16. Specifically, since the mating groove 17 is a rectangular groove with rounded corners at the four corners, during the process that the pushing portion 16 drives the movable member 6 to move through the mating groove 17, the pushing portion 16 can move unobstructed in the length direction of the mating groove 17. Therefore, the movable member 6 will not move significantly left and right. And since the pushing portion 16 cannot move unobstructed in the width direction of the mating groove 17, the movable member 6 will be forced to move in the front-back direction, thereby realizing the forward and backward rotation of the water outlet member 9.

[0045] As shown by Figure 2 and Figure 6As shown, in this embodiment, the connecting member 8 is provided with a connecting groove 20, and the movable member 6 is provided with a driving section 19 that extends outward and is inserted into the connecting groove 20. Among them, the connecting groove 20 is arranged at the upper part of the connecting member 8, and the water outlet member 9 is connected to the lower part of the connecting groove 20. Specifically, the connecting member 8 is provided with a connecting hole adapted to the water outlet member 9 at its lower part, and the water outlet member 9 is provided with a limiting protrusion that restricts its relative rotation with the connecting hole. Of course, in another embodiment, the water outlet member 9 and the connecting member 8 can be in interference fit. In addition, in this embodiment, the diameter of the driving section 19 is smaller than the diameter of the connecting groove 20, and the rotation amplitude of the water outlet member 9 can be adjusted through the gap between the connecting groove 20 and the driving section 19. For example, by increasing the gap between the connecting groove 20 and the driving section 19, the rotation amplitude of the water outlet member 9 can be reduced; by reducing the gap between the connecting groove 20 and the driving section 19, the rotation amplitude of the water outlet member 9 can be increased.

[0046] Of course, the rotation amplitude of the water outlet member 9 in this embodiment can also be adjusted by the width dimension of the mating groove 17. The larger the width dimension of the mating groove 17, the smaller the rotation amplitude of the water outlet member 9, and vice versa, the smaller the width dimension of the mating groove 17, the larger the rotation amplitude of the water outlet member 9.

[0047] In addition, it should be noted that annular seals are provided between the upper cover 2 and the body 7, and between the water outlet member 9 and the body 7 for sealing, which will not be elaborated here.

[0048] Through the above scheme of this embodiment, the water outlet device of this case can utilize the pressure of the incoming water, and finally drive the water outlet member 9 to rotate forward and backward through the inclined water member 3, the impeller 4, the gear 5, the movable member 6 and the connecting member 8, so that the water outlet member 9 forms a front-back swinging water outlet. Since the water outlet member 9 rotates forward and backward by the front-back swing of the movable member 6, the reliability of the forward and backward rotation of the water outlet member 9 is high, and the problem of being stuck will not occur. In addition, the water outlet member 9 of this embodiment can set the forward and backward rotation angles of the water outlet member 9 through the clearance between the connecting groove 20 and the driving section 19, and the width dimension of the mating groove 17, etc. The rotation angle of the water outlet member 9 can be increased reliably and conveniently as required, and then the water outlet swing angle of the water outlet member 9 can be increased to achieve a better shower effect.

[0049] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
