[0038] Example 1

[0039] refer to Figure 1-Figure 12 This embodiment provides an intermittent water outlet device, including: a housing 1, and an intermittent water outlet mechanism composed of an inclined water body 2, a small-tooth difference reduction mechanism 3, a water diversion plate 4 and a water diversion body 5; wherein the small-tooth difference reduction mechanism 3 is provided with a rotor 33 as an input component, an external gear 31 as an output component, and a linkage mechanism 32; the direction of water inflow is changed through the inclined water holes 21 of the inclined water body 2, so that the outflow water flow in each inclined water hole 21 can hit the rotor 33 along the same rotation direction, driving the rotor 33 to rotate. The rotor 33 then drives the external gear 31 to rotate through the linkage mechanism 32, and then the external gear 31 drives the water diversion plate 4 to rotate relative to the water diversion body 5, so that the water diversion plate 4 can connect the water outlet holes 51 in different areas on the water diversion body 5, and realize the switching of the water outlet holes 51.

[0040] Therefore, the shell 1 is provided with a water inlet 11 and a chamber for accommodating the intermittent water outlet mechanism, and the intermittent water outlet mechanism can be installed in the shell 1, and the water inlet 11 of the shell 1 is connected to an external water supply pipe to complete a complete water outlet device.

[0041] In this embodiment, the water distribution plate 4 is to connect the water outlet holes 51 in different areas of the water distribution body 5 during the rotation process. The water distribution plate 4 is provided with water holes 41, and the number of the water holes 41 is less than the number of the water outlet holes 51, so that the water distribution plate 4 intermittently connects the water outlet holes 51 in area A or area B of the water distribution body 5 during the rotation process. In this embodiment, there are 12 water outlet holes 51 and 6 water holes 41; thus, there are 6 water outlet holes 51 in area A and 6 water outlet holes 51 in area B. Moreover, the water outlet holes 51 in area A and the water outlet holes 51 in area B are arranged at intervals to form two adjacent ones. Figure 4 Two different areas are indicated in the figure and separated by a line. It should be noted that this line is only used to distinguish different areas and does not exist on the actual product.

[0042] The water outlet device in this embodiment further includes a surface cover 6 , and the surface cover 6 is arranged downstream of the water diversion body 5 along the water outlet direction.

[0043] Since this intermittent water outlet device is mainly used to achieve the effect of massage by having water flow intermittently hit a certain part of the user. If the water outlet angles of all the water outlet holes 51 are the same, due to the different positions of the water outlet holes 51, the areas covered by the water outlets of different water outlet holes 51 will inevitably be different, that is, the positions hit by different water outlet holes are different. In this way, when water is discharged from area A and area B, the areas of the user's body hit by the water are not the same. The user feels that the water outlet hitting point is always changing, which makes the user feel bad. Therefore, in this embodiment, two adjacent water outlet holes 51 are arranged as a group, and the water outlet angles of the water outlet nozzles 62 on the face cover 6 corresponding to the same group of water outlet holes 51 are different, so that the water outlet directions of the water outlet nozzles 62 corresponding to a group of two adjacent water outlet holes 51 are arranged facing each other, such as Fig.10 As shown. To achieve such a water outlet effect, the two water outlets 62 corresponding to a group of water outlet holes 51 can be set to be symmetrical, and the two water outlets 62 are respectively inclined toward the axis of symmetry. In this way, there is an intersection in the water outlet paths of the two water outlets 62. By adjusting the inclination angle so that this intersection is located exactly on the user's body, the striking areas of the two water outlets 62 can be made roughly the same. Thereby, at different time points, the positions struck by the two adjacent water outlets 62 are the same. In this way, when water is discharged from area A and area B, the position on the human body hit by the water flow is roughly the same, which can bring a better massage effect to the user. And since only one area of ​​the water outlet holes 51 is discharging water at any time, this can also achieve the effect of saving water.

[0044] The function of the speed reduction mechanism 4 is to slow down the rotation speed of the water diversion plate 4, so that the water outlet intervals of the water outlet holes 51 in the A area and the B area are lengthened, and the effect of intermittent massage is more obvious. The rotor 33 in the small-tooth difference speed reduction mechanism 3 in this embodiment is arranged in the chamber through the pin shaft 3, and the rotating shaft 33 can rotate around the pin shaft 34, and the water diversion plate 4 is connected to the outer gear 31 in a circumferential swinging manner. The linkage mechanism 32 is a fixed gear ring arranged on the inner wall of the water diversion body 5; the outer gear 31 is meshed with the fixed gear ring. The transmission ratio of the speed reduction mechanism 4 can be set as needed, so that the intermittent time can be adjusted to adapt to different needs.

[0045] Specifically, the outer gear 31 is arranged between the rotor 33 and the water separation plate 4, and a clearance hole 311 is arranged at the axis of the outer gear 31 for the pin shaft 34 to pass through. In addition, the rotor 33 in this embodiment is an eccentric impeller, and the eccentric impeller achieves eccentric cooperation with the clearance hole 311 during the eccentric rotation process, thereby driving the outer gear 31 to rotate eccentrically.

[0046] A fixing column 42 is extended axially from one side of the water-dividing plate 4 toward the external gear 31, and the external gear 31 is provided with a yaw hole 312 plugged with the fixing column 42. In this embodiment, the yaw holes 312 are distributed in an equilateral triangle, and the center of the equilateral triangle coincides with the axis of the water-dividing plate 4. Specifically, the yaw hole 312 is larger than the fixing column 42 by 2 eccentricities. In this way, the eccentric rotation of the external gear 31 causes the yaw hole 312 to also rotate eccentrically relative to the fixing column 42, thereby driving the water-dividing plate 4 to rotate.

[0047] In order to assemble the housing 1 and the intermittent water outlet mechanism, the inner wall of the chamber is provided with an internal thread 12, and the outer wall of the water diversion body 5 is provided with an external thread 52 that matches the internal thread 12. In this way, the water diversion body 5 can be fixed in the chamber, and the inclined water body 2 and the small-tooth difference speed reduction mechanism 3 are respectively arranged in the water diversion body 5.

[0048] In addition, in order to fix the surface cover 6 , a slot hole 53 is provided on the lower surface of the water diversion body 5 , and the surface cover 6 is provided with an insert rib 61 that is plugged and matched with the slot hole 53 .

[0049] Example 2

[0050] refer to Fig.13 The difference between this embodiment and embodiment 1 is that the water outlet device in this embodiment is specifically a shower head. Since the water outlet area of ​​the shower head is relatively large, compared with the single-circle structure of the water outlet holes 51 in embodiment 1, the water outlet holes 51 in this embodiment are arranged in concentric circles, and the water outlet holes 51 in area A and the water outlet holes 51 in area B are arranged at intervals on the same circumference to form pairs of adjacent ones.

[0051] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
