Technical Field

The utility model relates to the technical field of bathroom equipment, in particular to a water outlet device and a shower head.

Background

There is the gondola water faucet that can produce the galloping spray on the market, and the galloping spray can bring better visual experience for the user. However, in the prior art, such a shower head capable of generating a waving spray has a small coverage area of the waving spray. For example, the nozzle of the shower can swing back and forth to realize the waving of the water flow, however, the track formed by the swing of the tail end of the waving spray is a straight line, the coverage area of the waving spray is relatively slender, and the coverage area of the waving spray is smaller. For example, the nozzle of the shower can rotate to realize the waving of the water flow, however, the track formed by the rotation of the tail end of the waving spray is a circle, the area in the middle of the circle cannot be contacted with the waving spray, and the coverage area of the waving spray is smaller. The smaller area of coverage of the galloping spray means that in the case where the user holds the shower head in his hand and keeps the shower head stationary, the area where the user's skin can contact the galloping spray is smaller and the user's shower experience is poor.

Fig. 1 shows a water outlet device 100 according to an embodiment of the present utility model, and fig. 2 is an exploded view of the water outlet device 100 of fig. 1. Referring to fig. 1 and 2, the water outlet device 100 includes a housing 101, a driving mechanism 215, a water outlet nozzle 210, a first transmission member 213, a second transmission member 206, a rotation member 211, and a swing member 208.

Referring to fig. 1, a housing 101 has a water inlet 102, and water can enter the water outlet device 100 from the water inlet 102. The spout 210 has a water outlet 103, and the dashed path in fig. 3 represents the flow path of water in the shower head, as shown in fig. 3, from which water can flow out of the water outlet 103 and out of the water outlet device 100. In order to avoid that the housing 101 blocks water from flowing out of the water outlet 103, the housing 101 is provided with a first avoiding hole 106, and an end of the water outlet nozzle 210 provided with the water outlet 103 is arranged in the first avoiding hole 106. The housing 101 may be assembled from a plurality of components, for example, in fig. 1, the housing 101 includes an upper shell 104 and a lower shell 105. The upper case 104 and the lower case 105 may be coupled together by screw coupling; alternatively, the upper shell 104 and the lower shell 105 are connected together in a clamping manner; alternatively, the upper case 104 and the lower case 105 are coupled together by screws. Accordingly, the water inlet 102 is provided at the top of the upper case 104, and the first escape hole 106 is provided at the bottom of the lower case 105.

Referring to fig. 2 and 3, the first transmission member 213 and the second transmission member 206 are connected to a driving mechanism 215, the rotation member 211 and the swinging member 208 are connected to the water outlet nozzle 210, and the rotation member 211 is connected to the first transmission member 213 and the swinging member 208 is connected to the second transmission member 206. The driving mechanism 215 is capable of driving the first transmission member 213 to rotate, thereby rotating the rotation member 211 and the water nozzle 210 relative to the housing 101 about the first axis 301. The driving mechanism 215 is also capable of driving the second transmission member 206 to rotate so as to rotate the swinging member 208 relative to the rotating member 211, thereby driving the water outlet nozzle 210 to swing about the second axis 302 relative to the rotating member 211. As shown in fig. 3, the first axis 301 and the second axis 302 are not parallel and are not collinear; more specifically, in fig. 3, the first axis 301 and the second axis 302 are perpendicular to each other.

Fig. 4 shows a coverage area 403 of a spray of a single nozzle 210 of the water outlet device 100 in the present utility model, and the coverage area 403 of the spray of the water outlet device 100 of the present utility model is large because the nozzle 210 can rotate while swinging. The coverage area 403 of the water bloom is explained here. As shown in fig. 4, assuming that the water outlet device 100 is fixed relative to a water receiving surface 401, the end of the water outlet stream 402 emitted from the water outlet device 100 contacts the water receiving surface 401, and the area on the water receiving surface 401 that can contact the water outlet stream 402 is the coverage area 403 of the water spray of the water nozzle 210. In a practical use scenario, the water receiving surface 401 may be the surface of some articles to be rinsed with water, or may be the skin of the user.

Fig. 5 shows a water spray coverage area 403 of a water outlet device in the prior art, a water outlet nozzle of the water outlet device is rotatable, a track formed by a tail end of a water outlet water flow 402 sprayed by a single water outlet nozzle on a water receiving surface 401 is a circle (or a circular ring), and a region surrounded by the circle in the water receiving surface 401 is not in contact with water flow in practice, so that the water spray coverage area 403 of the single water outlet nozzle is smaller, and the water spray coverage area 403 of the whole water outlet device is smaller. Fig. 6 shows a coverage area 403 of a spray of another water outlet device in the prior art, a water outlet nozzle of the water outlet device can swing, a track formed by a tail end of a water outlet flow 402 sprayed by a single water outlet nozzle on a water receiving surface 401 is a straight line, and the straight line is relatively slender, so that the coverage area 403 of the spray of the single water outlet nozzle is smaller, and the spray coverage area 403 of the whole water outlet device is smaller.

With the water outlet device 100 of the present utility model, since the water outlet nozzle 210 can swing, the end of the water outlet flow 402 reciprocates along a straight line on the water receiving surface 401; at the same time, the water outlet nozzle 210 can also rotate with respect to the water receiving surface 401, and the end of the water outlet flow 402 can also rotate with respect to the water receiving surface 401. Therefore, the coverage area 403 of the water spray of the single water nozzle 210 of the water outlet device 100 of the present utility model is a circular area, and the circular area is not an internal hollow circular area, and the water spray coverage area 403 of the water outlet device 100 of the present utility model is larger.

In order to make the swing direction and the rotation direction of the water outlet nozzle 210 different, the first axis 301 and the second axis 302 do not have to be perpendicular, and it is only necessary to ensure that the first axis 301 and the second axis 302 are not collinear and not parallel, and an included angle between the first axis 301 and the second axis 302 may be an acute angle or an obtuse angle.

In one embodiment, the drive mechanism 215 is powered by the flow of water into the water outlet apparatus 100. Referring to fig. 7, the drive mechanism 215 includes a body of diagonal water 204 and an impeller 202. Referring to fig. 3, the oblique water body 204 is installed inside the upper case 104, and the oblique water body 204 is fixed relative to the upper case 104. As shown in fig. 7, the diagonal water body 204 has a water passing chamber 501 and diagonal water ports 502 penetrating through both ends, and the diagonal water ports 502 are provided on the wall surface of the water passing chamber 501. The inclined water gap 502 is communicated with the water inlet 102, and the water passing cavity 501 is communicated with the water outlet 103. The water entering the water outlet device 100 from the water inlet 102 may then flow through the inclined water gap 502, the water passing chamber 501 and the water outlet 103 in this order. The impeller 202 is rotatably disposed in the water passage chamber 501. For example, as shown in fig. 3, the driving mechanism 215 further includes a mandrel 203 and a water diversion cover 201, the water diversion cover 201 is connected to the top of the oblique water body 204 to cover the top opening of the water passing cavity 501, two ends of the mandrel 203 are fixedly connected with the water diversion cover 201 and the lower shell 105 respectively, the mandrel 203 penetrates through the impeller 202, and the impeller 202 can rotate around the mandrel 203. The first transmission member 213 and the second transmission member 206 are both connected to the impeller 202, and when the impeller 202 rotates, the impeller 202 can rotate the first transmission member 213 and the second transmission member 206. As shown in fig. 7, the central axis of the inclined water port 502 is disposed along the tangential direction of the impeller 202, and when water enters the water passing cavity 501 from the inclined water port 502, the water can push the impeller 202 to rotate. The advantage of using the water flow to drive the impeller 202 and thus the first and second transmission members 213, 206 to rotate is that: the water outlet device 100 does not need to be provided with a motor, the power consumption of the water outlet device 100 in the using process is low, and the energy conservation of the water outlet device 100 is better; in addition, the water outlet device 100 has fewer charged components, and the water outlet device 100 has high safety in use.

In another embodiment, the beveled gate 502 may be positioned elsewhere in order to allow the water flow to drive the impeller 202 in rotation. For example, based on fig. 3, the inclined nozzle 502 is disposed on the water diversion cover 201 of the driving mechanism 215, and a projection of the central axis of the inclined nozzle 502 on a reference plane is disposed along a tangential direction of the impeller 202, wherein the reference plane is a plane perpendicular to the central axis of the mandrel 203. Furthermore, in some embodiments, the impeller 202 is fixedly connected to the first transmission member 213 and the impeller 202 is fixedly connected to the second transmission member 206, the first transmission member 213, the second transmission member 206, and the impeller 202 being capable of synchronous rotation.

Referring to fig. 14 and 15, the eccentric protrusion 614 is provided in the abutment groove 612, and when the swing member 208 rotates relative to the rotation member 211, the eccentric protrusion 614 rotates about the first axis 301, and the eccentric protrusion 614 abuts against a wall surface of the abutment groove 612, thereby pushing the water nozzle 210 to swing about the second axis 302. For example, referring to fig. 14 and 15, the second axis 302 extends in the left-right direction, and when the swinging member 208 rotates counterclockwise (based on a top view angle) with respect to the rotating member 211, the eccentric protrusion 614 may push against the front side wall surface of the groove 612, thereby swinging the end (bottom end) of the spout 210 provided with the water outlet 103 backward, and the eccentric protrusion 614 may also push against the rear side wall surface of the groove 612, thereby swinging the end of the spout 210 provided with the water outlet 103 forward.

Therefore, when the rotator 211 rotates relative to the housing 101, the wall surface of the abutment groove 612 abuts the swing shaft 611, and the rotator 211 pushes the water outlet nozzle 210 to rotate around the first axis 301; when the swinging member 208 rotates relative to the rotating member 211, the eccentric protrusion 614 pushes the water nozzle 210 to swing around the second axis 302. Thus, the tap 210 can be swung and rotated simultaneously with respect to the housing 101.

Referring to fig. 13, the swing member 208 includes a first sleeve portion 613, the third teeth 605 are disposed on the outer periphery of the first sleeve portion 613, and the first sleeve portion 613 is disposed around the eccentric protrusion 614. Referring to fig. 11, the rotation member 211 includes a second sleeve portion 608, the fourth tooth 606 is coupled to an outer side of the second sleeve portion 608, and the mounting groove 607 is provided at an inner side surface of the second sleeve portion 608. The first sleeve portion 613 and the second sleeve portion 608 are each cylindrical. The structure formed after the swing member 208, the rotation member 211 and the water outlet nozzle 210 are assembled is shown in fig. 14 and 15. The first sleeve portion 613 is rotatably fitted over the second sleeve portion 608, and the first sleeve portion 613 is fitted over the outer portion of the end (tip) of the nozzle 210 where the abutment groove 612 is provided. The assembly structure of the water outlet nozzle 210, the swinging piece 208 and the rotating piece 211, which are sleeved layer by layer, is beneficial to improving the compactness among all parts in the water outlet device 100, thereby being beneficial to reducing the volume of the water outlet device 100.

As shown in fig. 14, the bottom end of the first sleeve portion 613 is also pressed against the swing shaft 611; as can be seen from fig. 11 and 14, the bottom end of the first sleeve portion 613 can prevent the swing shaft 611 from being separated from the mounting groove 607, thereby improving the positional stability of the swing shaft 611. As shown in fig. 15, the first sleeve portion 613 is provided with a second escape hole 615, and in combination with fig. 3 and 15, water leaving the water passing chamber 501 flows to the second escape hole 615, then enters the water outlet nozzle 210 from openings at both left and right ends of the abutment groove 612, and finally flows out from the water outlet 103 at the bottom of the water outlet nozzle 210.

If the water outlet device 100 is used on a shower, the end of the water outlet stream 402 can massage the skin of the user as the water outlet nozzle 210 oscillates back and forth. If the frequency of the swing of the water outlet nozzle 210 is increased, the massage effect of the water outlet flow 402 is enhanced. Thus, to increase the oscillation frequency of the spout 210, in some embodiments, the ratio of the number of fourth teeth 606 to the number of first teeth 604 is a, and the ratio of the number of third teeth 605 to the number of second teeth 601 is b,0 < b < a. Since the first transmission member 213 and the second transmission member 206 are coaxial and relatively fixed, the rotational speeds of the first transmission member 213 and the second transmission member 206 are the same; on the basis of this, 0 < b < a, the rotational speed of the swinging member 208 can be made higher than the rotational speed of the rotating member 211, thereby increasing the swinging frequency of the water outlet nozzle 210.

Still further, a >1 and 0 < b < 1 may be provided, which may accelerate the oscillating member 208 relative to the driving mechanism 215 and decelerate the rotating member 211 relative to the driving mechanism 215. The advantage of this arrangement is that, on the one hand, the speed difference between the swinging member 208 and the rotating member 211 can be increased, and the swinging frequency of the water outlet nozzle 210 can be increased; on the other hand, the rotation speed of the rotation member 211 and the nozzle 210 can be reduced, so that the rotation speed of the water outlet flow 402 of the water outlet device 100 is reduced, and the visual effect of the water outlet flow 402 is improved.

For example, in a particular embodiment, the number of fourth teeth 606 is 30, the number of first teeth 604 is 22, a = 30/22; the number of third teeth 605 is 28 and the number of second teeth 601 is 80, b=28/80.

In one embodiment, it is contemplated that the speed of the first and second transmission members 213, 206 relative to the impeller 202 may be slowed, thereby reducing the speed of the rotation member 206. Reducing the rotational speed of the rotating member 211 is beneficial to slowing down the rotational speed of the outlet water flow of the outlet nozzle 210 and improving the visual effect of the outlet water flow 402.

Specifically, referring to fig. 16, the water outlet device 100 further includes a differential gear 205, wherein the differential gear 205 is fixed relative to the impeller 202, the differential gear 205 is eccentrically disposed relative to the impeller 202, and a central axis of the differential gear 205 is parallel to a rotation axis of the impeller 202. The inner periphery of the oblique water body 204 is provided with a plurality of first decelerating teeth 701, and the central axis of the oblique water body 204 is collinear with the rotation axis of the impeller 202. The outer periphery of the difference gear 205 has a plurality of second reduction teeth 702, the number of the second reduction teeth 702 being smaller than the number of the first reduction teeth 701, the second reduction teeth 702 being meshed with the first reduction teeth 701. In fig. 16, the number of second reduction teeth 702 is 42, and the number of first reduction teeth 701 is 43. The second transmission member 206 has a water passing hole 503, and the water passing hole 503 is communicated with the water passing cavity 501; more specifically, the second transmission member 206 includes ribs 603, where the ribs 603 are spaced apart along the circumference of the mandrel 203, and two adjacent ribs 603 together define a water through hole 503. The differential gear 205 has an abutment post 703, and the abutment post 703 is provided in the water passing hole 503. The water exiting from the water chamber 501 may then flow through the water passage 503, the second relief hole 615, the abutment groove 612, and the water outlet 103 in that order.

When the impeller 202 rotates, the differential gear 205 rotates in synchronization with the impeller 202, and the rotation of the differential gear 205 relative to the diagonal body 204 can be approximately regarded as the rolling of the differential gear 205 along the inner wall surface of the diagonal body 204; when the differential gear 205 rotates, the abutment post 703 abuts against the wall surface of the water passing hole 503, thereby pushing the second transmission member 206 to rotate. In this arrangement, the body of water 204 and the differential gear 205 together form a planetary reduction mechanism with little tooth difference. In other embodiments, the speed reduction mechanism may be replaced by a planetary gear speed reduction mechanism, a worm gear speed reduction mechanism, or the like.

Referring to fig. 2, the water outlet device 100 further includes a fixing member 207, a bracket 209, a first sealing ring 214, and a second sealing ring 212. Both the mount 207 and the bracket 209 are fixed relative to the housing 101. Referring to fig. 3, the swinging member 208 is rotatably sleeved outside the cylindrical protrusion of the fixing member 207, and the swinging member 208 penetrates the bracket 209, thereby achieving a rotational connection between the swinging member 208 and the housing 101. The first seal 214 is clamped between the upper and lower cases 104 and 105, the second seal 212 is clamped between the spout 210 and the lower case 105, and the first and second seals 214 and 212 serve to prevent water from flowing out from a position other than the water outlet 103.
