Description

Technical Field

[0001] This application relates to, but is not limited to, the field of bathroom fixtures technology, specifically to a jet water generator and a water outlet device. Background Technology

[0002] Among related technologies, devices with pulsed water flow massage function are widely favored because they can bring a soothing and relaxing effect. However, when the daily water supply pressure is low or the water pressure fluctuates during peak water usage, the pulse effect of such devices will be greatly reduced, failing to achieve the expected massage effect and making it difficult to meet the user's needs under different water pressure conditions. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a jet water flow generator and a water outlet device, which is beneficial to meeting the user's needs for pulse water flow under different water pressure conditions.

[0004] This application provides a jet water generator, comprising: a housing with a water storage chamber inside; a power turntable rotatably disposed within the water storage chamber, configured to drive water to flow from the inlet end of the housing to the outlet end of the housing through its own rotation, thereby increasing the water pressure at the outlet end; and a water outlet assembly disposed downstream of the power turntable, the water outlet assembly having a first water passage that can be intermittently opened and closed, so that the jet water generator can intermittently jet water.

[0005] After entering the water storage chamber, the water is first pressurized by the power turntable. The pressurized water is then transported to the downstream water outlet component. When the first water passage of the water outlet component opens, the high-pressure water jet is quickly ejected. When the first water passage of the water outlet component closes, the power turntable continues to store power, ultimately achieving a cycle of storage and jetting. In this way, even under low water pressure conditions, the power turntable can store power to form a pulsed water jet with strong impact, achieving a stable and uniform massage impact without the need for additional high-pressure water supply equipment. At the same time, it effectively improves the energy utilization rate of the water flow, which helps to ensure the stability and continuity of the intermittent jetting effect, meets the user's needs under different water pressure conditions, and improves the user experience.

Detailed Implementation

[0022] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0023] like Figures 1-3 As shown, this application embodiment provides a jet water generator 100, including a housing 1, a power turntable 2, and a water outlet assembly 3.

[0024] like Figures 10-12 As shown, the outer casing 1 is provided with a water storage cavity 121, and the power turntable 2 is rotatably disposed in the water storage cavity 121. It is configured to drive water to flow from the water inlet end of the outer casing 1 to the water outlet end of the outer casing 1 through its own rotation, so as to increase the water pressure at the water outlet end.

[0025] The water outlet assembly 3 is located on the downstream side of the power turntable 2. The water outlet assembly 3 is provided with a first water passage that can be opened and closed intermittently so that the jet water generator 100 can intermittently spray water.

[0026] After the water flows into the water storage chamber 121, it is first pressurized by the power turntable 2. The pressurized water is then transported to the downstream water outlet component 3. When the first water passage of the water outlet component 3 is opened, the high-pressure water jet is quickly ejected. When the first water passage of the water outlet component 3 is closed, the power turntable 2 continues to store power, ultimately achieving a cycle of storage and jetting. In this way, even under low water pressure conditions, the power turntable 2 can store power to form a pulsed water jet with strong impact force, ensuring a stable and uniform massage impact without the need for additional high-pressure water supply equipment. At the same time, it effectively improves the energy utilization rate of the water flow, ensuring the stability and continuity of the intermittent jetting effect, and meeting the user's needs under different water pressure conditions.

[0027] In one exemplary embodiment, the power turntable 2 includes a rotating shaft 21 and power blades 22. The rotating shaft 21 extends along a direction from the water inlet end of the housing 1 to the water outlet end. The power blades 22 are connected to the rotating shaft 21 and include a plurality of helical blades 221 arranged axially along the rotating shaft 21, such as... Figure 4 As shown, in this embodiment of the application, there are 3 spiral blades 221. Of course, the number of spiral blades 221 can also be selected according to specific needs.

[0028] Thus, the spiral blade 221 rotates coaxially with the rotating shaft 21. The contact between the spiral surface of the spiral blade 221 and the water flow converts the torque of the rotating shaft 21 into a thrust that propels the water flow. Through the rotation direction of the spiral surface of the spiral blade 221 and the force of the water flow, a thrust is applied to the water flow from the inlet end to the outlet end, increasing the pressure of the water flow.

[0029] In one exemplary embodiment, a plurality of helical blades 221 are interconnected to form an integral structure.

[0030] In this way, the helical blade 221 with its integrated structure has good guidance and structural stability. When rotating, it can apply continuous and uniform thrust to the water flow, effectively avoiding thrust fluctuations and water backflow, and reducing pressure loss.

[0031] In one exemplary embodiment, combined with Figures 10-12 As shown, the water outlet component 3 includes a first water control element 31 and a second water control element 32. The second water control element 32 is located upstream of the first water control element 31. The first water control element 31 is provided with a first water passage, and the second water control element 32 is provided with a second water passage. The first water passage can communicate with the second water passage to form a first water passage.

[0032] The second water control element 32 is configured to rotate relative to the first water control element 31, so that the first water passage is connected to or disconnected from the second water passage, thereby causing the first water passage to open and close intermittently.

[0033] Thus, when the second water passage of the second water control component 32 rotates to connect with the first water passage of the first water control component 31, the first water passage is opened, and the water flow pressurized by the power turntable 2 is ejected from the first water passage to form a pulsed water flow with impact force. When the second water passage of the second water control component 32 rotates to be misaligned with the first water passage of the first water control component 31, the first water passage is closed, and the power turntable 2 stores power in preparation for the next ejection.

[0034] In one exemplary embodiment, one of the first water control element 31 and the second water control element 32 is connected to the power turntable 2 and rotates synchronously with the power turntable 2, so that the second water control element 32 can rotate relative to the first water control element 31. For example, the rotation shaft 21 of the power turntable 2 is connected to the second water control element 32 to drive the second water control element 32 to rotate. In this case, the second water control element 32 is the rotor and the first water control element 31 is the stator.

[0035] This configuration eliminates the need for an additional structure to control the rotation of the second water control element 32 in the jet water generator 100. This not only helps to reduce the size of the jet water generator 100 and achieve a compact design, but also reduces the cost of adding an extra structure.

[0036] Of course, the rotational power for controlling the second water control element 32 can also be provided by other structures, such as by driving the second water control element 32 to rotate through an additional drive device, which can be a motor, pneumatic device, hydraulic device, etc. In other embodiments, the second water control element 32 can also be a stator and the first water control element 31 can be a rotor, in which case the rotation shaft 21 of the power turntable 2 is connected to the first water control element 31 to drive the first water control element 31 to rotate.

[0037] In one exemplary embodiment, combined with Figure 5 , Figure 6 as well as Figures 10-12 As shown, the first water passage includes several water holes 311, and the second water passage is an arc-shaped groove 321, which extends circumferentially along the power turntable 2.

[0038] The water passage 311 can be, but is not limited to, a circular hole. The width of the arc-shaped groove 321 can be adapted to the diameter of the water passage 311. The dimension of the arc-shaped groove 321 along the circumference of the second water control element 32 is smaller than the interval dimension of the adjacent water passage 311 along the circumference of the first water control element 31. Thus, the second water control element 32 can rotate to a position that covers the water passage 311 or to a position that opens the water passage 311. As the second water control element 32 rotates, the water passage 311 cycles between covering and opening, while the power turntable 2 also cycles between water flow storage and pulse impact. Only when the arc-shaped groove 321 on the second water control element 32 connects with the water passage 311 on the first water control element 31 will the pressure be released, causing the water to jet out. Figure 17 As shown. The arc-shaped groove 321 has a certain length and can maintain a certain duration of communication with the water passage 311 to avoid the water jet duration being too short.

[0039] In an exemplary embodiment, a first flow gap 14 is provided between the power blade 22 and the sidewall of the water storage chamber 121, and a second flow gap 15 is provided between the first water control element 31 and the second water control element 32, as shown below. Figure 13 As shown.

[0040] In some embodiments, the second water control element 32 is provided with second support protrusions 322 spaced circumferentially, such as... Figure 6 As shown, the second water control element 32 abuts against the first water control element 31 through the second support protrusion 322, and a third flow gap 323 is formed between adjacent second support protrusions 322. The first flow gap 14 is connected to the second flow gap 15 through the third flow gap 323.

[0041] In this way, when the first water passage and the second water passage are misaligned, some water will flow through the first flow gap 14 and then through the third flow gap 323 to the second flow gap 15, and then flow out through the first water passage to discharge, thereby ensuring that the power turntable 2 can rotate normally and store power when the first water passage and the second water passage are misaligned without being blocked.

[0042] Moreover, the setting of the second support protrusion 322 reduces the contact area between the first water control element 31 and the second water control element 32, thereby reducing the frictional resistance when the power turntable 2 drives the second water control element 32 to rotate, and reducing the consumption of water flow energy.

[0043] In one exemplary embodiment, such as Figure 9As shown, the jet water generator 100 also includes a drive wheel 5, which is rotatably mounted inside the housing 1 and connected to the power turntable 2 to drive the power turntable 2 to rotate.

[0044] The rotating shaft 21 of the power turntable 2 can cooperate with the drive wheel 5, enabling the drive wheel 5 to drive the power turntable 2 to rotate. The drive wheel 5 is provided with multiple drive blades 51, which are spaced apart along the circumference of the drive wheel 5.

[0045] Thus, when the water flows through the drive wheel 5, the water flow will impact the drive blades 51 to provide driving power to drive the drive wheel 5 to rotate, and in turn drive the power turntable 2 to rotate.

[0046] In one exemplary embodiment, such as Figures 11-12 As shown, the outer casing 1 is also provided with a water passage cavity 111, which is located on the upstream side of the water storage cavity 121. The drive wheel 5 is installed in the water passage cavity 111. A partition 13 is provided between the water passage cavity 111 and the water storage cavity 121. The partition 13 is provided with a first water passage 131 connecting the water passage cavity 111 and the water storage cavity 121.

[0047] In this way, while the water flows into the upstream water passage 111 to drive the drive wheel 5 to rotate, it also enters the water storage chamber 121 from the water passage 111 via the first water outlet 131 to provide power-storing water flow for the power turntable 2. Furthermore, this arrangement can prevent the water inlet of the water storage chamber 121 from being completely open, which is beneficial to improving the power storage effect of the water flow in the water storage chamber 121.

[0048] In an exemplary embodiment, the water passage cavity 111 is provided with first support protrusions 132 spaced circumferentially along the power turntable 2, and the drive wheel 5 is rotatably supported on the first support protrusions 132.

[0049] The first support protrusion 132 can be disposed on the partition 13 between the water passage cavity 111 and the water storage cavity 121. In this way, the contact area between the drive wheel 5 and the partition 13 is reduced, thereby reducing the frictional resistance of the drive wheel 5 during rotation, reducing the loss of force of water flow acting on the drive wheel 5, and further ensuring the smoothness of the rotation of the drive wheel 5. In addition, a fourth flow gap can be formed between the drive wheel 5 and the partition 13, which communicates with the first water passage 131, so as to facilitate the rapid entry of water flow into the water storage cavity 121.

[0050] In an exemplary embodiment, the water outlet assembly 3 is further provided with a second water passage. The cavity wall of the water passage chamber 111 is provided with a water passage hole 1111. The water passage hole 1111 is separated from the water storage chamber 121 and connected to the second water passage, so that some water in the water passage chamber 111 can flow into the second water passage through the water passage hole 1111 and the water passage channel 203 outside the water storage chamber 121 as described below. Figure 16 As shown.

[0051] In this way, even when the first water passage is closed, some water can still flow out continuously from the second water passage, ensuring the continuity of the water flow. When the first water passage is open, the jet water generator 100 has an intermittent pulse water jet effect while the water flow is continuous.

[0052] In some embodiments, the diameter of the water passage cavity 111 is larger than the diameter of the water storage cavity 121, and the water passage hole 1111 is located at the connection between the side wall of the water passage cavity 111 and the partition plate 13. The second water passage includes a plurality of second water passage ports 312 disposed on the side wall of the first water control element 31. The outer side wall of the first water control element 31 is flush with the outer side wall of the outer casing 1. In this way, the structure of the jet water generator is relatively regular, which is convenient for both processing and assembly in the water outlet device.

[0053] The first water control component 31 can be fixedly connected to the outer shell 1 by means of screwing, snapping, or bonding, or it can simply abut against the outer shell 1. When the first water control component 31 abuts against the outer shell 1 at one end, the first water control component 31 and the outer shell 1 can be limited in the axial and circumferential directions by means of other structures that cooperate with it, thereby indirectly achieving the fixed connection between the first water control component 31 and the outer shell 1.

[0054] In one exemplary embodiment, such as Figure 7 , Figure 8 , Figure 10 As shown, the jet water generator 100 also includes a guide vane 4, which is located upstream of the drive wheel 5 and has a guide channel 41 that communicates with the water passage 111. The guide channel 41 supplies water to the drive wheel 5 to drive the drive wheel 5 to rotate.

[0055] Thus, the water flows into the guide vane 4, and through the guide channel 41 into the water passage 111. The water flowing into the water passage 111 impacts the drive blades 51 of the drive wheel 5, thereby driving the drive wheel 5 to rotate.

[0056] In an exemplary embodiment, the flow channel 41 is provided with a first inclined flow guide surface 411 and a second inclined flow guide surface 412 that are relatively spaced apart along the circumference of the drive wheel 5. Along the direction from the flow guide plate 4 to the drive wheel 5, the first inclined flow guide surface 411 and the second inclined flow guide surface 412 both extend obliquely along the circumference of the drive wheel 5.

[0057] Thus, when the water enters the guide channel 41, it will flow out along the direction of the first inclined guide surface 411 and the second inclined guide surface 412, thereby generating a rotational driving force on the drive wheel 5 to drive the drive wheel 5 to rotate, and thus the water flow can be guided into a directional flow.

[0058] In an exemplary embodiment, along the rotation direction of the drive wheel 5, the first inclined guide surface 411 is located upstream of the second inclined guide surface 412. The inlet end of the guide channel 41 is provided with a first drop step 413, which is located on the side of the second inclined guide surface 412 away from the drive wheel 5 and connected to it. The outlet end of the guide channel 41 is provided with a second drop step 414, which is located on the side of the first inclined guide surface 411 near the drive wheel 5 and connected to it. The guide vane 4 is located at the end of the water passage cavity 111 away from the water storage cavity 121.

[0059] In this way, the first drop step 413 increases the water inlet area of ​​the guide channel 41, thus increasing the amount of water entering the guide channel 41. The second drop step 414 increases the water outlet area of ​​the guide channel 41, thus increasing the amount of water flowing out of the guide channel 41. This increases the contact area between the water flow and the drive blades 51 of the drive wheel 5, and correspondingly increases the driving power of the drive wheel 5.

[0060] This application embodiment also provides a water outlet device, including: a water outlet body 200 and a jet water generator 100 as described in any of the above embodiments, wherein the jet water generator 100 is disposed within the water outlet body 200, such as... Figures 14-15 As shown.

[0061] The water outlet device provided in this application embodiment has all the above-mentioned beneficial effects because it includes the jet water generator 100 of any of the above embodiments, and will not be described again here.

[0062] In one exemplary embodiment, combined with Figure 1 , Figure 11 , Figure 12 , Figure 15 as well as Figure 16 As shown, the outer shell 1 includes a first tube shell 11 and a second tube shell 12 connected to the first tube shell 11. The first tube shell 11 is provided with a water passage cavity 111, and the second tube shell 12 is provided with a water storage cavity 121. The first tube shell 11 is attached to the inner wall of the water outlet body 200, and a water passage channel 203 is formed between the second tube shell 12 and the inner wall of the water outlet body 200.

[0063] The water passage connects the water hole 1111 to the second water passage. In this way, water enters the water passage 111, passes through the water hole 1111, the water passage 203, and the second water passage in sequence, and then flows out. Even if the first water passage is closed, water can still flow out continuously from the second water passage, ensuring the continuity of the water flow.

[0064] In one exemplary embodiment, such as Figures 15-16As shown, the water outlet body 200 includes a handle 201 and a shower head water outlet body 202 connected to the handle 201. The jet water generator 100 is entirely built into the handle 201, overcoming the problems of low space utilization, large size, and inability to disassemble and maintain caused by the traditional pulse device being built into the water path of the shower head water outlet body 202. The handle 201 is provided with a limiting step 2011, and the guide vane 4 is in a stop-fitting engagement with the limiting step 2011. The water outlet component 3 is in a stop-fitting engagement with the shower head water outlet body 202, and the first water passage and the second water passage of the water outlet component 3 are both connected to the water inlet of the shower head water outlet body 202.

[0065] In this way, the jet water generator 100 can be installed as an independent module in the water outlet device without the need for additional water flow boosting equipment. This modular design not only simplifies the assembly process of the water outlet device and the difficulty of subsequent inspection and maintenance, but also makes it easier to upgrade or replace the jet water generator 100. It can also be flexibly combined according to different usage scenarios, improving the versatility of the product. At the same time, modular mass production reduces the overall manufacturing cost.

[0066] In summary, the jet water generator and water outlet device of this application achieve a cycle of power storage and jetting through a power turntable rotatably located in the water storage chamber. In this way, even under low water pressure conditions, a pulse water flow with strong impact force can be generated, significantly improving the experience of water splash impact and meeting the user's needs under different water pressure conditions. Moreover, the jet water generator adopts a modular design, which is characterized by being detachable for cleaning, easy to replace and maintain. It is convenient to upgrade or replace the jet water generator or adapt it to different needs. It can also be flexibly combined according to different usage scenarios, improving the versatility of the product. At the same time, modular mass production reduces the overall manufacturing cost.
