Description

TECHNICAL FIELD

[0001] The present application relates to a water outlet device. BACKGROUND

[0002] Shower is a kind of shower equipment widely used in life. When the shower is used for a long time or in a place with poor water quality, the hole wall of the water outlet hole on the water outlet surface cover is easy to attach scale. After accumulation for a long time, the scale will block the water outlet hole, resulting in that the shower cannot be used normally. Therefore, there are many showers with descaling function on the market. Generally, a descaling plate with a plurality of descaling needles arranged on the bottom surface is movably arranged in the shower, and the descaling plate is driven to move by manual or water flow. In the existing descaling products, the descaling plate moves along the axial direction. In order to ensure that the descaling plate can move smoothly, a certain gap must be left between the top pin and the inner wall of the water outlet hole, otherwise the descaling plate cannot move normally due to the excessive friction between the top pin and the inner wall of the water outlet hole. However, after the gap is left between the top pin and the inner wall of the water outlet hole, the scale attached to the inner wall of the water outlet hole cannot be completely removed, resulting in that the water spray is easy to be obliquely shot, and the purpose of cleaning the scale cannot be achieved. SUMMARY

[0003] The main technical problem to be solved by the present application is to provide a self-cleaning water outlet device. During the water outlet process, the top pin swings around the axis in the water outlet hole of the water outlet surface cover, so that the scale attached to the inner wall of the water outlet hole is automatically removed.

[0004] Another main technical problem to be solved by the present application is to provide a self-cleaning water outlet device, which comprises a body, a descaling needle plate arranged in the body, and a rotating member driven to rotate around the axis.

[0005] The descaling needle plate and the water outlet surface cover are coaxially arranged along the axial direction, and the descaling needle plate has a plurality of top pins. The descaling needle plate is swing-connected with the rotating member.

[0006] When the water outlet device is filled with water, the water flow drives the rotating member to rotate, and the rotating member further drives the top pin to swing around the axis in the water outlet hole of the water outlet surface cover. During the swinging process of the top pin, the scale attached to the inner wall of the water outlet hole is top-pressed and rubbed, so that the scale attached to the inner wall of the water outlet hole is removed with the swinging of the top pin.

[0016] In a preferred embodiment: the end of the movable member located in the chamber is a water storage end. When no water flows into the chamber from the inlet, the reset member drives the descaling needle plate to move upward along the axial direction, thereby causing the water storage end to move upward along the axial direction to the inlet.

[0017] The present invention also provides a swing water outlet device, comprising: a main body, a water flow reversing component placed inside the main body, and a rotating component that is driven by water flow to rotate about an axial direction;

[0018] The water flow reversing component and the water outlet cover are coaxially arranged along the axial direction, and the water flow reversing component has a plurality of reversing units; the water flow reversing component is oscillatingly connected to the rotating component;

[0019] When water enters the water outlet device, the water flow drives the rotating component to rotate, and the rotating component in turn drives the reversing unit to swing around the axial direction in the water outlet hole of the water outlet cover, so that the direction of water flow in the water outlet hole changes with the swing of the reversing unit.

[0020] In a preferred embodiment: the body contains an inclined water body, the inclined water body has a chamber, one end of the chamber is provided with an inlet arranged along the axial direction, and the side wall of the chamber is provided with a plurality of inclined outlets along the circumferential direction.

[0021] In a preferred embodiment: the rotating component is an impeller, which is disposed outside the chamber side wall of the inclined water body; the water flow enters the impeller from the inclined outlet and impacts the blades of the impeller, causing the impeller to rotate.

[0029] In a preferred embodiment: the end of the movable member located in the cavity is a water storage end.

[0030] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0031] 1. This invention provides a self-cleaning water outlet device. The impeller rotation drives a descaling needle plate to oscillate, thereby achieving the purpose of the needle oscillating axially within the water outlet hole of the outlet cover. During the oscillation, the needle abuts and rubs against the inner wall of the water outlet hole, causing the scale adhering to the inner wall of the water outlet hole to fall off with the oscillation of the needle. Compared with the traditional method of the needle moving axially, the method of this invention allows for more thorough removal of scale adhering to the inner wall of the water outlet hole, making the water spray less oblique and achieving a very good descaling effect.

[0032] 2. The self-cleaning water outlet device provided by this invention has a descaling needle plate that moves axially upward when the water is turned off and downward along the axial direction when the water is turned on. Therefore, when the water is turned off, the needle will not be inserted into the water outlet hole, and there will be no residual water at the water outlet hole. This eliminates the possibility of residual water and bacterial growth between the water outlet hole and the needle.

[0033] 3. The self-cleaning water outlet device provided by this invention allows for continuous descaling throughout the entire water outlet process, whereas in traditional methods, descaling is completed instantaneously when water is turned on or off, resulting in a very short descaling time. Undoubtedly, the solution of this invention provides a longer descaling time and therefore a better descaling effect.

[0034] 4. The self-cleaning water outlet device provided by this invention seals the water inlet at one end of the moving part when the water is off. Therefore, when water is supplied, this water storage end has a certain water storage function. Only when the water pressure reaches a certain value will the moving part move downward along the axis to fully open the water inlet. This results in a relatively fast initial water flow velocity into the chamber, and a relatively fast initial rotation speed of the impeller. Consequently, the oscillation speed of the ejector pin increases, the friction between the ejector pin and the inner wall of the water outlet increases, and the descaling force increases accordingly.

[0035] 5. The present invention provides a swinging water outlet device. When water is flowing through it, a rotating component drives a reversing unit to swing axially within the water outlet hole of the outlet cover. During the swinging process, the reversing unit abuts against the inner wall of the water outlet hole, partially sealing the outlet hole, causing the water flow direction in the outlet hole to change with the swinging of the reversing unit. This can form large water droplets with a conical swinging effect, resulting in a more uniform water droplet distribution, a large coverage area, and a pulsating effect, providing an excellent showering experience.

[0045] To better understand the technical content of this invention, specific implementation methods are described below in conjunction with the accompanying drawings.

[0046] refer to Figures 1-9 A self-cleaning water outlet device is provided. In this embodiment, the water outlet device is preferably, but not limited to, a shower head. The shower head includes: a body 1, a descaling needle plate 2 disposed within the body 1, and a rotating component 3 that is driven by water flow to rotate about an axial direction.

[0047] The descaling needle plate 2 and the water outlet cover 11 are coaxially arranged along the axial direction, and the descaling needle plate 2 has a plurality of pins 21; the descaling needle plate 2 is oscillatingly connected to the rotating component 3.

[0048] When water enters the water outlet device, the water flow drives the rotating component 3 to rotate. The rotating component 3 then causes the ejector pin 21 to swing axially within the water outlet hole 111 of the water outlet cover 11. During this swinging motion, the ejector pin 21 rubs against the scale adhering to the inner wall of the water outlet hole 111, causing the scale to detach as the ejector pin 21 swings. Compared to the traditional method of the ejector pin moving axially, this descaling method allows for more thorough removal of scale from the inner wall of the water outlet hole, resulting in a much better descaling effect. This solves the problem of traditional descaling methods where scale between the ejector pin and the inner wall of the water outlet hole cannot be removed.

[0049] To achieve the above structure, in this embodiment, the main body 1 has an inclined water body 12, which has a chamber 121. One end of the chamber 121 is provided with an axially oriented water inlet 122, and the sidewall of the chamber 122 is provided with a plurality of circumferentially oriented water outlets 123. The inclined water body 12 converts the axial water inlet into an inclined water outlet.

[0050] The rotating component 3 is an impeller, which is located outside the side wall of the chamber 121 of the inclined water body 12; the water flows into the impeller from the inclined outlet 123, impacting the blades of the impeller and driving the impeller to rotate.

[0051] To enable the impeller to drive the descaling needle plate 2 to swing, a cam 31 extends axially downward from the side of the impeller facing the descaling needle plate 2, and a connector 22 extends axially upward from the side of the descaling needle plate 2 facing the inclined water body 12. The cam 31 is inserted into the connector 22 and the side wall of the cam 31 abuts against the side wall of the connector 22. When the impeller rotates, the cam rotates within the connector 22, and the abutting force between the inner wall of the cam and the connector 22 drives the descaling needle plate 2 to swing.

[0052] Meanwhile, in order for the shower head to function properly, the water flowing into the impeller also needs to flow out normally from the outlet holes 111 of the outlet cover 11. For this purpose, the impeller has an outlet 32 ​​at its lower end along the axial direction. Water enters the impeller through the inclined outlet 123 and then flows from the outlet 32 ​​to the descaling needle plate 2. The descaling needle plate 2 has an axially arranged flow passage 23, through which water flows into the outlet holes 111 of the outlet cover 11, thus forming the normal shower head water flow.

[0053] This achieves the goal of normal water flow from the showerhead and descaling during water flow. However, the above technical solution requires the ejector pin 21 to remain inside the water outlet hole 111 at all times. After the water is turned off, residual water will remain in the gap between the ejector pin 21 and the water outlet hole 111. If this residual water cannot be completely drained, bacteria can easily grow between the ejector pin 21 and the water outlet hole 111. Therefore, a more reasonable technical solution would be one where the ejector pin 21 enters the water outlet hole 111 for descaling during water flow and is removed from the water outlet hole 111 when the water is turned off, allowing the residual water in the water outlet hole 111 to be completely drained.

[0054] To achieve the above-mentioned effect, in this embodiment, the main body 1 further includes a movable component 4 that moves axially driven by water flow; the descaling needle plate 2 and the movable component 4 are connected axially; therefore, when water enters the shower head, the water flow drives the movable component 4 to move the descaling needle plate 2 downward along the axial direction, causing the pin 21 to move into the water outlet hole 111 of the water outlet cover 11. This achieves the goal of the pin 21 entering the water outlet hole 111 for descaling when water is flowing through it.

[0055] To further facilitate the removal of the pin 21 from the water outlet 111 when the water is turned off, a reset member 5 is provided between the descaling pin plate 2 and the water outlet cover 11; when the descaling pin plate 2 moves downward along the axial direction, the reset member 5 accumulates elastic reset force. Therefore, when the water is turned off, this elastic reset force drives the descaling pin plate 2 to move upward along the axial direction to reset.

[0056] To facilitate the installation of the movable component 4, the end of the chamber 121 away from the inlet 122 is provided with an axial through hole 124. One end of the movable component 4 passes through the through hole 124 and is connected to the descaling needle plate 2. The other end of the movable component 4 is located inside the chamber 121. When water flows into the chamber 121 from the inlet 122, the water flow collides with the movable component 4, causing the movable component 4 to move downward along the axial direction.

[0057] The cam 31 is provided with a relief hole 33 along the axial direction. The moving part 4 is inserted into the connector 22 through the relief hole 33 and abuts against the bottom end face of the connector 22 along the axial direction.

[0058] In this embodiment, in order to further optimize the descaling efficiency, one end of the moving part 4 located in the chamber 121 is a water storage end 41. When no water flows into the chamber 121 from the water inlet 122, the reset part 5 drives the descaling needle plate 2 to move upward along the axial direction, thereby causing the water storage end 41 to move upward along the axial direction to the water inlet 122.

[0059] The purpose of this design is to ensure that the water storage end 41 has a certain water storage function during water flow. Only when the water pressure reaches a certain value will the moving part 4 move downward along the axial direction to fully open the water inlet 122. This results in a relatively fast initial water flow velocity into the chamber 121, and a relatively fast initial speed of the impeller. Consequently, the oscillation speed of the ejector pin 21 increases, the friction between the ejector pin 21 and the inner wall of the water outlet 111 increases, and the descaling force is thus enhanced.

[0060] Finally, because the ejector pin 21 oscillates axially within the outlet hole 111 during water discharge, it objectively affects the direction of water flow within the outlet hole 111. Therefore, for the water spray, the ejector pin 21 acts as a reversing unit, and the entire descaling needle plate 2 acts as a water flow reversing component. The reversing unit's oscillation causes the water flow direction in the outlet hole 111 to change accordingly. This creates large water droplets with a conical oscillation effect, resulting in a more uniform water droplet distribution, a wider coverage area, and a pulsating effect, providing an excellent shower experience.

[0061] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
