It includes an inlet chamber, a flow chamber, an impeller, and an outlet hole. The inlet chamber and the outlet hole are connected via the flow chamber. The flow chamber has an inclined water channel. The impeller is disposed within the flow chamber and rotates due to the impact of the inclined water flow formed by the inclined water channel. The impeller has a water-blocking part and a pressure-bearing part. The water-blocking part is configured to intermittently block the outlet hole as the impeller rotates.

Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and more specifically, to a pulse water outlet structure and water outlet device. Background Technology

[0002] Most existing pulse-jet showerheads, such as the one disclosed in Chinese patent CN106733255A, include, from top to bottom, an upper plate with a water inlet, a water distribution plate with a water outlet, and a water outlet panel with spray nozzles. The water distribution plate has an impeller rotatably connected to it and intermittently blocks the water outlet by rotating. This creates a pulsed water flow at the outlet, providing a massage effect to the user. This type of design is simple and widely used in pulse-jet showerheads. However, in this structure, the impeller rotates faster with increasing water pressure, leading to an unstable pulse-jet frequency. The faster the pulse-jet frequency, the weaker the massage effect. Utility Model Content

[0003] This utility model discloses a pulse water outlet structure, which aims to improve the problem that the water outlet frequency of existing pulse water structures is easily affected by changes in water pressure.

[0004] The present invention adopts the following solution:

[0005] A pulsed water outlet structure includes an inlet chamber, a flow chamber, an impeller, and an outlet. The inlet chamber and the outlet are connected via the flow chamber. The flow chamber has an inclined water channel. The impeller is disposed within the flow chamber and rotates due to the impact of the inclined water flow formed by the inclined water channel. The impeller has a water-blocking part and a pressure-bearing part. The water-blocking part is configured to intermittently block the outlet as the impeller rotates. The pressure-bearing part is at least partially exposed in the inlet chamber, so that the rotational resistance experienced by the impeller within the flow chamber is positively correlated with the water flow pressure.

[0006] As a further improvement, the impeller is configured such that the frictional force between it and the water passage cavity increases with the increase of water flow pressure.

[0007] As a further improvement, the top of the water inlet chamber is provided with a water inlet channel, and the pressure-bearing part is located on the top surface of the impeller and below the water inlet channel.

[0008] As a further improvement, both the water-blocking part and the pressure-bearing part are integrally formed with the impeller.

[0009] As a further improvement, it includes an inlet component, an outlet component, and a water passage component. The inlet component and the outlet component are connected to form the inlet cavity. The water passage component is disposed in the inlet cavity to form the water passage cavity with the outlet component. The outlet hole is disposed on the outlet component and located at the bottom of the water passage cavity.

[0010] As a further improvement, the bottom inner side of the water outlet component is provided with a mounting part, the impeller is sleeved on the mounting part, and the pressure-bearing part extends into the mounting hole of the water passage component.

[0011] As a further improvement, the impeller is provided with a rotating shaft, one end of which is sleeved on the mounting part, and the other end forms the pressure-bearing part.

[0012] As a further improvement, a seal is fitted onto the shaft to seal with the mounting hole.

[0013] As a further improvement, the cross-sectional shape of the water passage component is annular, and multiple inclined water channels are arranged in an array along the circumference of the water passage component.

[0014] Another water outlet device is provided, including a water outlet body and a pulse water outlet structure as described in any of the preceding claims disposed on the water outlet body.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. In this application's pulse water outlet structure, water enters from the inlet chamber, flows through the inclined water channel into the through-chamber, and finally sprays out from the outlet hole. After entering through the inclined water channel, the water impacts the blades on the impeller, causing it to rotate. This intermittently blocks the outlet hole, creating a pulsed water flow. The pressure-bearing part ensures that as the water pressure in the inlet chamber increases, the pressure on the pressure-bearing part also increases, correspondingly increasing the rotational resistance on the impeller. This reduces the impeller's rotational speed when the water impacts the blades. This also means that under the same water pressure, the pulse water outlet structure of this application has a lower pulse frequency compared to existing technologies, resulting in a better pulsed water massage effect. The rotational resistance on the impeller can be the friction between the impeller and the through-chamber. As the water pressure increases, the friction between the impeller and the through-chamber also increases, thus reducing the impact of water pressure on the impeller's rotational speed, ensuring the stability of the pulse water outlet frequency, and improving the user experience.

[0017] 2. Both the water-blocking part and the pressure-bearing part are integrally formed with the impeller, which can reduce assembly and lower the precision requirements of parts, thereby reducing costs. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0033] Combination Figures 1 to 6 This embodiment provides a pulsed water outlet structure, including an inlet chamber 1, a water passage chamber 2, an impeller 3, and an outlet hole 4. Specifically, the inlet chamber 1 and the outlet hole 4 are connected through the water passage chamber 2. The water passage chamber 2 is provided with an inclined water groove 21. The impeller 3 is disposed in the water passage chamber 2 and rotates due to the impact of the inclined water flow formed by the inclined water groove 21. The impeller 3 is provided with a water-blocking part 31 and a pressure-bearing part 32. The water-blocking part 31 is configured to intermittently block the outlet hole 4 as the impeller 3 rotates. The pressure-bearing part 32 is at least partially exposed in the inlet chamber 1 so that the rotational resistance experienced by the impeller 3 in the water passage chamber 2 is positively correlated with the water flow pressure.

[0034] It should be noted that in this embodiment, water enters from the inlet chamber 1, flows into the through chamber 2 via the inclined water channel 21, and finally sprays out from the outlet hole 4. After entering from the inclined water channel 21, the water impacts the blades 33 on the impeller 3, causing the impeller 3 to rotate. This causes the water-blocking part 31 to intermittently block the outlet hole 4, thus forming a pulsed water flow. The setting of the pressure-bearing part 32 means that when the water pressure in the inlet chamber 1 increases, the pressure on the pressure-bearing part 32 also increases, correspondingly increasing the rotational resistance of the impeller 3. This reduces the rotational speed of the impeller 3 when the water impacts the blades 33. This also means that under the same water pressure, the pulsed water flow structure of this embodiment has a lower pulse frequency compared to the prior art, resulting in a better pulsed water massage effect. The rotational resistance experienced by the impeller 3 can be the friction between the impeller 3 and the through chamber 2. When the water pressure increases, the friction between the impeller 3 and the through chamber 2 also increases, thereby reducing the impact of water pressure on the rotational speed of the impeller 3, ensuring the stability of the pulsed water flow frequency, and improving the user experience.

[0035] In a preferred embodiment, the top of the water inlet chamber 1 is provided with a water inlet channel, and the pressure-bearing part 32 is provided on the top surface of the impeller 3 and located below the water inlet channel to ensure that the water flow pressure can act on the pressure-bearing part 32. Preferably, both the water-blocking part 31 and the pressure-bearing part 32 are integrally formed with the impeller 3, which can reduce assembly, reduce the precision requirements of parts, and thus reduce costs. The water-blocking part 31 is formed on the bottom surface of the impeller 3 and is connected to at least two blades 33.

[0036] Based on the above embodiments, in an optional embodiment of this utility model, the pulse water outlet structure includes an inlet component 5, an outlet component 6, and a water passage component 7. The inlet component 5 and the outlet component 6 are connected to form an inlet cavity 1. The water passage component 7 is disposed in the inlet cavity 1 to form a water passage cavity 2 with the outlet component 6. The outlet hole 4 is disposed on the outlet component 6 and located at the bottom of the water passage cavity 2. Exemplarily, the inlet component 5 and the outlet component 6 are connected by threads to facilitate the assembly and disassembly of the pulse structure. The water passage component 7 and the outlet component 6 can be fixed by welding to reduce the assembly of the sealing component 35 and ensure the water flow direction between the inlet cavity 1 and the water passage cavity 2, so that the oblique water flow formed by the oblique water tank 21 can drive the impeller 3 to rotate. Multiple outlet holes 4 are arranged in an array along the center of the outlet component 6. During the rotation, the water blocking part 31 sequentially blocks each outlet hole 4, so that the blocked outlet hole 4 stops water discharge, while the unblocked outlet hole 4 discharges water. It should be mentioned that the bottom of the water passage chamber 2 is provided with a clearance groove 22 to avoid excessive friction between the impeller 3 and the water passage chamber 2, which would cause the water output frequency to be too slow.

[0037] In one embodiment, the inner bottom of the water outlet 6 has a protruding mounting portion 61, the impeller 3 is sleeved on the mounting portion 61, and the pressure-bearing portion 32 extends into the mounting hole 71 of the water passage component 7. Specifically, the impeller 3 is provided with a rotating shaft 34, one end of which is sleeved on the mounting portion 61, and the other end forms the pressure-bearing portion 32. The pressure-bearing portion 32 is preferably flat, with a simple structure and convenient disassembly and assembly. Preferably, the rotating shaft 34 is recessed with an assembly groove, on which a sealing element 35 is sleeved for sealing with the mounting hole 71. The sealing element 35 is preferably a V-ring or a Y-ring to enhance the sealing performance between the sealing element 35 and the inner wall of the mounting hole 71.

[0038] In other embodiments, the cross-sectional shape of the water-passing component 7 is annular, and multiple inclined water grooves 21 are arranged in an array along the circumference of the water-passing component 7 to ensure the water flow rate entering the water-passing cavity 2. At the same time, the arrangement of multiple inclined water grooves 21 can also ensure that the impeller 3 can be driven to rotate smoothly. The inclination direction of the inclined water grooves 21 can be the tangential direction of the water-passing component 7, but is not limited to this and is not specifically limited.

[0039] This utility model also provides a water outlet device, including a water outlet body 8 and a pulse water outlet structure as described in any of the above embodiments, disposed on the water outlet body 8. The water outlet body 8 can be a shower head, spray gun, bidet, faucet, or other device with a water outlet function. By providing a pulse water outlet structure on the water outlet body 8, the water outlet device can generate pulsed water with a stable frequency.

[0040] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
