Description

Technical Field

[0001] The utility model relates to the technical field of water outlet devices, in particular to a water outlet device. Background Art

[0002] With technological advancements and rising living standards, bathroom products are becoming increasingly intelligent, health-conscious, and comfortable. In the water distribution sector, traditional faucets and showers are no longer able to meet modern consumers' pursuit of a high-quality lifestyle. Consumers demand not only basic water delivery functions but also additional health benefits and comfort features, such as massage functions, to alleviate daily fatigue and enhance enjoyment while bathing or cleaning.

[0003] However, the functional design of water dispensers currently on the market still has many shortcomings. For one thing, some products, despite their simple design, have limited functionality and can only provide basic water delivery services. They lack innovation and personalization, making it difficult to meet consumers' growing demand for diversified and healthy water treatments.

[0004] On the other hand, although some high-end water outlet devices integrate multiple functions, such as massage effects, these products are often complex in structure, high in manufacturing cost, and difficult to maintain and service on a daily basis, which brings inconvenience to consumers. Utility Model Content

[0005] The purpose of the utility model is to provide a water outlet device, which, through the clever cooperation of two impellers, can adjust the water output and impact force of different water outlets to achieve the effect of pulse water outlet, thereby meeting consumers' demand for massage function and maintaining the simplicity of the device's structure and cost-effectiveness.

[0006] To achieve the above-mentioned purpose, the solution of the present invention is: a water outlet device, comprising a body, a first impeller and a second impeller;

[0007] The body has an inner cavity, and is provided with at least one water inlet and two water outlets communicating with the inner cavity;

[0008] The first impeller and the second impeller are both rotatably disposed in the inner cavity of the body, with their rotation axes being parallel but not overlapping, the first impeller being provided with a driving member for driving the second impeller, and the second impeller being provided with a water diversion portion;

[0009] Water flows into the inner cavity from the water inlet of the main body, driving the first impeller to rotate. The driving member on the first impeller drives the second impeller to rotate. The water diversion part on the second impeller rotates to gradually reduce the water flow area of one water inlet and gradually increase the water flow area of the other water outlet.

[0010] Furthermore, the two water outlets on the main body are arranged at intervals along the rotation direction of the second impeller, and the water flow surface of the water outlet is parallel to the plane of the second impeller.

[0011] Furthermore, a water diversion hole is provided on the water diversion part of the second impeller. The rotation of the second impeller drives the water diversion hole and one water outlet to be gradually misaligned to reduce the water flow area of the water outlet. At the same time, the water diversion hole and the other water outlet gradually overlap to increase the water flow area of the water outlet.

[0012] Furthermore, the second impeller is a groove wheel with pin grooves formed between adjacent blades. A round pin is radially provided on the first impeller. During the rotation process, the round pin enters the pin groove of the groove wheel and drives the groove wheel to rotate intermittently.

[0013] Furthermore, the outer periphery of the blades of the second impeller is in an arc shape that gives way to the rotation axis of the first impeller.

[0014] Furthermore, the water inlet is arranged obliquely on the main body, and forms an angle with the blades of the first impeller for driving the first impeller to rotate.

[0015] Furthermore, there are multiple water inlets, which are spaced apart on the main body to form a uniform layout surrounding the outer periphery of the first impeller.

[0016] Furthermore, the inner side wall of the body is provided with an arc-shaped rib, and the surface of the first impeller is supported on the arc-shaped rib.

[0017] Furthermore, the body includes a front cover and a rear cover, which are buckled together to form the inner cavity.

[0018] Furthermore, the water inlet is arranged on the top of the rear cover, and the water outlet is arranged on the side of the rear cover.

[0019] After adopting the above solution, the beneficial effects of the utility model are:

[0020] The utility model proposes a water outlet device, which forms a transmission structure through two impellers. The first impeller is driven to rotate by the water flow entering the water inlet, and the power is transmitted to the second impeller. The second impeller controls the water outlet state after the water is discharged, thereby realizing the dynamic change of the water flow at the water outlet, that is, the adjustment of the water outlet volume and impact force, so as to achieve the effect of pulsed water discharge. When the large and small forces are switched to impact the user's body, a massage effect is simulated, bringing a comfortable experience to the user.

[0021] In addition, the water outlet device can achieve the above-mentioned pulsed water outlet effect only through the clever design of two impellers and the water inlet and outlet. It has a simple structure, saves costs, and is easy to maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] The utility model provides a water outlet device, the water inlet end of which is connected to an external water source, and the water outlet end is connected to a shower head 4, a faucet and other water-using equipment. Figures 1 to 8 As shown, the water outlet device mainly includes a body 1, a first impeller 2 and a second impeller 3.

[0038] like Figure 1 As shown, the body 1 has an inner cavity 13 for accommodating the remaining components and for passing water. The body 1 is provided with a water inlet 121 communicating with the inner cavity 13 and two independent water outlets: a first water outlet 122 and a second water outlet 123. Water enters the inner cavity 13 through the water inlet 121 and flows out through the two water outlets to the water-using equipment connected to the water outlet.

[0039] like Figure 2 and Figure 3 As shown, the first impeller 2 and the second impeller 3 are both rotatably disposed within the inner cavity 13 of the main body 1, and their rotation axes are parallel but do not overlap, that is, they are not coaxially disposed. The first impeller 2 is driven by the water flow entering from the water inlet 121 of the main body 1. That is, when the water flow enters from the water inlet 121, it will impact the blades of the first impeller 2 in one direction, thereby driving the first impeller 2 to rotate. In this embodiment, the water inlet 121 is located at the top of the main body 1 and is tilted on the main body 1, forming a certain angle with the blades of the first impeller 2. This angle ensures that the water flow entering from the water inlet 121 can accurately impact the blades, converting its own kinetic energy into the rotational energy of the first impeller 2, thereby driving the first impeller 2 to rotate.

[0040] The number of water inlet 121 is at least one, and may be multiple, such as Figure 3 As shown, multiple water inlets 121 are spaced apart on the body 1, forming a uniform layout around the periphery of the first impeller 2. Each water inlet 121 has an equal angle with its corresponding blade. This allows the water flow from each water inlet 121 to exert the same, uniform impact force on the corresponding blade, ensuring the smooth rotation of the first impeller 2.

[0041] like Figure 2 and Figure 3As shown, a transmission relationship is formed between the first impeller 2 and the second impeller 3, that is, the first impeller 2 will drive the second impeller 3 to rotate during the rotation process. In this embodiment, the second impeller 3 is a groove wheel, and a pin groove 31 is formed between adjacent blades of the groove wheel. A round pin 21 is radially provided on the first impeller 2, and the round pin 21 extends toward the second impeller 3. The first impeller 2 and the groove wheel partially overlap in different planes, so that the round pin 21 on the first blade can achieve the driving of the groove wheel. During the rotation of the first impeller 2, the round pin 21 on it gradually enters the pin groove 31 of the groove wheel and continues to rotate, driving the groove wheel and the first impeller 2 to rotate in the opposite direction. Here, the outer periphery of the blades of the groove wheel presents an arc shape that gives way to the rotation axis of the first impeller 2, avoiding possible collision or interference between the two during high-speed rotation.

[0042] like Figure 5 and Figure 6 As shown, after the first impeller 2 rotates to a certain angle, the round pin 21 will disengage the pin groove 31 of the sheave, thus entering an intermittent non-transmission phase. During this phase, the sheave loses the direct driving force from the first impeller 2 and temporarily stops rotating until the round pin 21 completes its circular motion and re-engages the pin groove 31 of the sheave, at which point the sheave will rotate again. This means that intermittent transmission exists between the first impeller 2 and the second impeller 3. During the period when the sheave stops rotating, water continues to flow into the water inlet 121, so the water outlet maintains its current state and continues to discharge water.

[0043] like Figure 1 As shown, two water outlets of equal size are located on the side wall of the body 1. The water flow surface of the water outlet is parallel to the plane of the second impeller 3, that is, perpendicular to the rotation axis of the second impeller 3. In addition, the two water outlets are spaced and symmetrically arranged on the body 1 along the direction of rotation of the second impeller 3. The rotation of the second impeller 3 is to switch the water discharge state of the water outlet. Therefore, the second impeller 3 is provided with a water diversion part 32, refer to Figure 1 A water diversion hole 33 is provided on the water diversion part 32, and a reinforcing rib 34 is provided in the middle of the water diversion hole 33. The rotation of the second impeller 3 drives the water diversion hole 33 to coincide with, partially coincide with, or stagger with the water outlet, thereby achieving different water outlet states.

[0044] It should be noted that the surface of the water diversion part 32 fits tightly against the inner wall of the shell at the water outlet to ensure that it forms a completely sealed contact surface, thereby effectively preventing water from flowing to the water outlet through any tiny pores or gaps outside the water diversion port, thereby ensuring the accuracy of the water flow path.

[0045] In order to improve the stability of the structure, an arc-shaped rib 124 is provided on the inner wall of the body 1 in contact with the first impeller 2. Figure 3After the first impeller 2 is mounted on the body 1, its surface is supported by the arcuate rib 124. This design balances the first impeller 2 and effectively prevents it from tilting or shaking during rotation. Simultaneously, the second impeller 3 is located on the side of the first impeller 2 away from the arcuate rib 124, creating a rational spatial layout that not only ensures the two impellers operate independently without interfering with each other, but also optimizes the water flow path and improves overall hydraulic performance.

[0046] As a further improvement of the structure, the body 1 is designed as a split structure that is easy to disassemble and assemble. Specifically: Figure 1 As shown, the body 1 includes a front cover 11 and a rear cover 12. The front cover 11 and the rear cover 12 can be interlocked by any structure, forming an inner cavity 13 therebetween. In this embodiment, the water inlet 121 and the water outlet are both located on the rear cover 12, with the water inlet 121 located at the top of the rear cover 12 and the water outlet located on the rear side wall of the rear cover 12. The top of the front cover 11 is also provided with a water inlet port 113 for connecting to an external water source, which is connected to the water inlet 121 of the rear cover 12.

[0047] like Figure 2 As shown, the inner side wall of the front cover 11 is provided with a first connecting post 111 and a second connecting post 112 at positions corresponding to the rotation axes of the first impeller 2 and the second impeller 3; Figure 1 As shown, the inner side wall of the rear cover 12 is provided with a first connecting groove 125 and a second connecting groove 126 at positions corresponding to the rotation axes of the first impeller 2 and the second impeller 3. The rotation axis of the first impeller 2 is connected to the first connecting column 111 and the first connecting groove 125 respectively. Similarly, the rotation axis of the second impeller 3 is connected to the second connecting column 112 and the second connecting groove 126 respectively, thereby realizing their rotational connection on the main body 1.

[0048] The joints of the various components described in this case are reasonably provided with seals to ensure that fluid leakage can be effectively prevented in various working environments.

[0049] The water outlet state switching process of the water outlet device of the utility model is as follows:

[0050] In a certain state, such as Figure 3 and Figure 4 As shown, water flows into the inner cavity 13 from the water inlet 121 of the body 1, driving the first impeller 2 to rotate, and then driving the second impeller 3 to rotate. At this time, the overlapping area between the water diversion hole 33 on the first impeller 2 and the first water outlet 122 gradually increases, while the overlapping area with the second water outlet 123 gradually decreases, that is, the water flow area of the first water outlet 122 is relatively increased, and the water flow becomes softer, while the water flow area of the second water outlet 123 is relatively reduced, the water flow is compressed and accelerated, and the impact force is enhanced.

[0051] The first impeller 2 continues to rotate until the round pin 21 is out of the pin groove 31 of the second impeller 3. Figure 5 and Figure 6 At this time, the intermittent stage is entered, the second impeller 3 stops rotating, the water inlet 121 continues to take in water, and the water outlet maintains the current state and continues to discharge water.

[0052] The first impeller 2 continues to rotate, driving the round pin 21 to complete the circular motion and re-engage the pin groove 31 of the second impeller 3, thus driving the second impeller 3 to rotate again. Figure 7 As shown, at this time, the relationship between the water flow area of the first water outlet 122 and the second water outlet 123 is reversed, and the water flow of the first water outlet 122 becomes strong and powerful, while the water flow of the second water outlet 123 becomes soft, and this cycle repeats, forming a dynamic and balanced massage rhythm, which effectively promotes blood circulation, relieves muscle tension, and brings benefits to users.

[0053] Figure 8 It shows a wide application scenario of the water outlet device in daily life, that is, its application on the shower head 4, which can improve the water outlet performance of the traditional shower head 4, including the intensity, distribution uniformity and dynamic changes of the water flow, and bring a massage experience to the user when bathing.
