Description

Technical Field

[0001] This invention relates to the field of sanitary ware, and in particular to a water outlet device with descaling function. Background Technology

[0002] In daily life, due to the small diameter of showerhead nozzles, impurities often clog the nozzles. In areas with hard water, scale often builds up at the nozzles, causing water flow to become skewed, flow to decrease, or even completely blocking the nozzles. To address this, current showerhead technology often uses a descaling rack to remove scale from the nozzles. Specifically, the descaling needles on the rack move relative to the nozzles to remove scale. Currently, showerheads with descaling functions use only one descaling rack, with each descaling needle corresponding to a specific nozzle. Therefore, high precision is needed to ensure the coaxiality of the descaling needles and nozzles to prevent them from getting stuck and malfunctioning. When the showerhead is large, the descaling rack also needs to be larger. However, since the descaling rack is an injection-molded part, the larger the injection molded part, the greater its tolerance, making it difficult to accurately ensure the coaxiality of the descaling needles and nozzles, significantly increasing the manufacturing difficulty of the descaling rack. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a water outlet device with descaling function, which adopts a zoned descaling method, thus solving the problem that the prior art cannot produce large-area descaling racks.

[0004] The technical solution adopted by this invention to solve its technical problem is: a water outlet device with descaling function, comprising a device body, the device body having a water inlet and multiple water outlet holes; and further comprising:

[0005] Multiple descaling racks are arranged inside the device body, and each descaling rack is equipped with multiple descaling needles, which correspond one-to-one with the water outlet holes within the range of the descaling rack.

[0006] A drive mechanism is provided on the main body of the device and works in conjunction with the plurality of descaling racks to drive the plurality of descaling racks to move synchronously in a direction away from the water outlet or in a direction that allows the descaling needle to be inserted into the water outlet.

[0007] Furthermore, the driving mechanism includes a water distribution plate and multiple movable units. The water distribution plate is provided with a water inlet structure and multiple water distribution sections connected to the water inlet structure. The water distribution plate is disposed within the main body of the device, and the water inlet structure is connected to the water inlet sections. The driving mechanism also includes movable units respectively provided for each water distribution section. Each movable unit is linked and cooperates with a descaling rack, so that the movable unit drives the descaling rack to move in a direction away from the water outlet by receiving water flow from the water distribution section.

[0008] Furthermore, the water distribution section includes a water distribution cavity, and the movable unit includes at least one slider, which is slidably disposed along the side of the water distribution section, and the slider and the corresponding descaling rack form an inclined surface engagement.

[0009] Furthermore, the surrounding walls of the water distribution chamber are provided with drainage holes corresponding to the positions of the slider, and the slider is provided with an impact surface facing the drainage holes and used to receive water flow.

[0010] Furthermore, the water distribution cavity is equipped with a driving component, which forms an inclined surface with the slider so that the driving component drives the slider to slide when driven by the water flow; the top of the driving component is provided with a water inlet groove, and the side wall of the driving component is provided with at least one water passage hole communicating with the water inlet groove. As the driving component is driven by the water flow, the water passage hole gradually protrudes outside the water distribution cavity.

[0011] Furthermore, there are multiple sliders arranged circumferentially along the water distribution cavity; the descaling rack has a vertically penetrating accommodating cavity in the middle, the surrounding walls of the water distribution cavity extend into the accommodating cavity, the slider of the movable unit is located in the accommodating cavity and forms an inclined surface cooperation with the protrusion provided in the accommodating cavity; the slider is provided with a water passage groove.

[0012] Furthermore, it also includes a guide bracket provided for each active unit, and the slider of the active unit is slidably connected to the guide bracket using a sliding guide structure; the guide bracket is provided with at least one drain hole, and the corresponding descaling needle of the descaling rack located above the guide bracket passes through the drain hole.

[0013] Furthermore, it also includes at least one reset member provided for each descaling rack, the reset member being used to reset the descaling rack in the direction in which its descaling needle is inserted into the water outlet hole; the reset member includes an elastic element and / or a magnetic assembly.

[0014] Furthermore, the device body includes a shell and a water outlet cover. The shell is provided with the water inlet, and the water outlet cover is provided with the plurality of water outlet holes. The shell and the water outlet cover are fixedly connected, and the two together form the inner cavity of the device body. The water distribution plate is fixedly connected with the water outlet cover, and the two together form a water outlet cavity that connects the water outlet holes and the water distribution section. The descaling rack and the movable unit are located in the water outlet cavity.

[0015] Furthermore, the water inlet includes a water inlet ball head and a water inlet component. The water inlet ball head is connected to the top of the outer shell, and the water inlet component is located inside the outer shell. The water outlet end of the water inlet ball head is connected to the water inlet structure through the water inlet component. The water inlet structure is a water inlet cavity. The water outlet cover is equipped with a water outlet sleeve.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Because this invention uses multiple descaling racks arranged in a way that each descaling rack is responsible for the descaling function of the water outlet within its corresponding range, achieving multi-area descaling, this invention ensures that the area of ​​each descaling rack is not too large while the total area of ​​the multiple descaling racks is relatively large. This meets the precision requirements of injection molding production, ensures the coaxiality of the descaling needle and the water outlet, and prevents the descaling needle from getting stuck and failing. This solves the problem that existing technologies cannot produce large-area descaling racks.

[0018] 2. The driving mechanism includes the water distribution plate and multiple movable units, enabling the present invention to use water flow to provide driving force to drive the synchronous movement of each descaling rack. This makes the present invention more convenient to use, and also enables the present invention to achieve synchronous movement of multiple descaling racks with a simple structure and fewer parts, thereby making the product easier to achieve a thinner profile.

[0019] 3. This invention uses a guide bracket to guide the movement of the slider, ensuring smooth and fixed movement. Specifically, the guide bracket has at least one drain hole, through which the corresponding descaling needle of the descaling rack located above the guide bracket passes. This allows for the appropriate arrangement of water outlets within the guide bracket's range, resulting in a relatively uniform distribution of the water outlets and improving upon the problem in existing descaling showerheads where water outlets cannot be arranged due to internal structural obstructions.

[0047] Example 1

[0048] Please see Figures 1-15As shown, a water outlet device with descaling function according to the present invention includes a device body, multiple descaling racks 6, and a drive mechanism. The device body has a water inlet 2 and multiple water outlet holes 91. The multiple descaling racks 6 are arranged in the device body, and each descaling rack 6 is provided with multiple descaling needles 61. The multiple descaling needles 61 correspond one-to-one with the water outlet holes 91 within the range of the descaling rack 6. Specifically, the number of descaling racks 6 is two, but not limited to this. The number of descaling racks 6 can be set more according to the size of the water outlet device, such as three or four. The two descaling racks 6 are arranged along the length direction of the device body. The drive mechanism is disposed in the device body and works in conjunction with the multiple descaling racks 6 to drive each descaling rack 6 to move synchronously in a direction away from the water outlet holes 91 or in a direction that inserts the descaling needles 61 into the water outlet holes 91. The descaling needles 61 are generally tapered structures that are wider at the top and narrower at the bottom.

[0049] The driving mechanism specifically includes a water distribution plate 4, which has a water inlet structure and multiple water distribution sections connected to the water inlet structure. The water distribution plate 4 is disposed within the main body of the device, and its water inlet structure is connected to the water inlet section 2. The driving mechanism also includes movable units corresponding to each water distribution section. Each movable unit is linked with a descaling rack 6, so that the movable unit is driven by the water flow from the water distribution section to drive the descaling rack 6 to move in a direction away from the water outlet 91. The movable units correspond one-to-one with the descaling rack 6. Since there are two descaling racks 6, there are also two movable units. In other embodiments, the driving mechanism is a manual driving mechanism. When descaling is required, the manual driving mechanism can be manually operated to drive each descaling needle to move synchronously in a direction away from the water outlet or to insert the descaling needle into the water outlet.

[0050] The water inlet structure of the water distribution plate 4 includes an inlet cavity 41, and each water distribution section includes a water distribution cavity 42. The movable unit includes at least one slider 7, which is slidably arranged along the side of the water distribution section (i.e., the water distribution cavity 42). The slider 7 and the corresponding descaling frame 6 form an inclined surface cooperation. Specifically, the slider 7 is provided with a first inclined surface 71, and the descaling frame 6 is provided with a second inclined surface 641. The first inclined surface 71 and the second inclined surface 641 are in contact and can slide relative to each other. There are multiple sliders 7, which are arranged circumferentially along the water distribution cavity 42. Specifically, there are two sliders 7, which are arranged approximately symmetrically. There are also two water distribution cavities 42, which are arranged along the sliding direction of the sliders 7. The water inlet cavity 41 includes a central water inlet area and two diversion areas that are interconnected. The central water inlet area is circular, and the two diversion areas are distributed on opposite sides of the central area. The two diversion areas are elongated and extend radially along the central water inlet area. The middle water inlet area of ​​the water inlet chamber 41 is opposite to the water inlet section 2, and the ends of the two diversion areas that are away from the middle water inlet area are respectively connected to the upper ends of the two diversion chambers 42.

[0051] The surrounding walls of the water distribution cavity 42 are provided with drainage holes 421 corresponding to the positions of the slider 7. The slider 7 has an impact surface 72 facing the drainage holes 421 and used to receive water flow. The impact surface 72 is an arc surface, corresponding to the circular outer side surface of the surrounding walls of the water distribution cavity 42. The impact surface 72 and the first inclined surface 71 of the slider 7 are located on two opposite sides of the slider 7. Figure 8 As shown. The slider 7 is provided with a water passage groove 73. Specifically, the water passage groove 73 is located on the top surface of the slider 7 and extends along the sliding direction of the slider 7. The end of the water passage groove 73 near the impact surface 72 is closed, while the end away from the impact surface 72 is open. There are multiple water passage grooves 73 arranged side by side. Specifically, there are two water passage grooves 73, but it is not limited to this. The purpose of providing the water passage groove 73 on the slider 7 is to provide a larger flow space for water between the slider 7 and the descaling rack 6, and to avoid the gap between the slider 7 and the descaling rack 6 being too small, which would affect the smooth flow of water.

[0052] The descaling rack 6 has a through-cavity 63 in its center. The walls of the water distribution cavity 42 extend into the cavity 63. Each slider 7 of the movable unit is located within the cavity 63 and forms an inclined surface engagement with the protrusions 64 within the cavity 63. Specifically, the protrusions 64 have a second inclined surface 641. Since there are two sliders 7, there are also two protrusions 64, which are arranged approximately symmetrically. Figure 4 As shown.

[0053] As a preferred embodiment, the present invention further includes a guide bracket 8 corresponding to each active unit, wherein each slider 7 of the active unit is slidably connected to the guide bracket 8 by a sliding guide structure. (See example 9.) Figure 10 As shown, the sliding guide structure specifically includes two parallel limiting ribs 81, each extending along the sliding direction of the slider 7. The slider 7 fits between the two limiting ribs 81 and can slide along their extension directions. The guide bracket 8 has at least one drain hole 82. The corresponding descaling needle 61 of the descaling rack 6 located above the guide bracket 8 passes through the drain hole 82, and the descaling needle 61 is clearance-fitted with the drain hole 82. Specifically, the guide bracket 8 has two drain holes 82, arranged perpendicular to the sliding direction of the slider 7. The arrangement of the drain holes 82 allows for the appropriate arrangement of water outlet holes 91 within the guide bracket 8, resulting in a relatively uniform arrangement of the water outlet holes 91 and improving the problem of not being able to arrange water outlet holes 91 when there is structural obstruction inside the existing descaling shower head.

[0054] The water distribution cavity 42 of the water distribution plate 4 has a bottom wall, making the bottom of the water distribution cavity 42 closed. A limiting protrusion 422 is provided in the middle of the outer end face of the bottom wall of the water distribution cavity 42. The guide bracket 8 is fitted below the water distribution cavity 42, and a limiting hole 83 is provided in the middle of the guide bracket 8. The limiting protrusion 422 is adapted to be inserted into the limiting hole 83 to provide a limit for the guide bracket 8. The shape of the limiting protrusion 422 and the limiting groove are both flat, specifically square, but not limited to this.

[0055] As a preferred embodiment, the present invention further includes at least one reset member corresponding to each descaling rack 6. This reset member is used to reset the descaling rack 6 in the direction in which its descaling needle 61 inserts into the water outlet 91. The reset member specifically includes an elastic element 5, which is specifically a spring, but not limited thereto. The elastic element 5 can be replaced by a magnetic assembly, or the reset member can include both the elastic element 5 and a magnetic assembly. Alternatively, the present invention may omit the reset member, allowing the descaling rack 6 to reset directly under its own weight.

[0056] The device body specifically includes an outer shell 1 and a water outlet cover 9. The outer shell 1 is provided with the water inlet 2, and the water outlet cover 9 is provided with multiple water outlet holes 91, and a water outlet sleeve is installed on the water outlet cover 9. The outer shell 1 and the water outlet cover 9 are fixedly connected (specifically by ultrasonic welding or screw fixing, etc.), and the two together form the inner cavity of the device body. The water distribution plate 4 is fixedly connected with the water outlet cover 9, and the two together form a water outlet cavity that connects the water outlet holes 91 and the water distribution part (i.e., the water distribution cavity 42). The descaling rack 6, the movable unit, the guide bracket 8, and the elastic element 5 are respectively located in the water outlet cavity. The water distribution plate 4 and the water outlet cover 9 are specifically fixed by multiple screws 3 (the water distribution plate 4 is provided with screw holes 44 corresponding to the screws 3), and the four edges of the water distribution plate 4 are snap-fitted to the water outlet cover 9. The bottom of the water distribution plate 4 is provided with water sealing ribs 46. The water distribution plate 4 and the outlet cover 9 are connected by a snap-fit ​​mechanism: multiple snap holes 45 are arranged around the perimeter of the water distribution plate 4, and snap fasteners 92 are provided on the outlet cover 9 corresponding to each snap hole 45. The snap fasteners 92 engage with the snap holes 45 one by one. This reduces the number of screws 3 used to fix the water distribution plate 4 and the outlet cover 9, thereby reducing production costs. Each descaling rack 6 has multiple elastic elements 5, specifically four, but not limited to this. The four elastic elements 5 are distributed at the four corners. The descaling rack 6 has a limiting post 62 at the position corresponding to the elastic element 5, and the water distribution plate 4 has a limiting groove 43 at the position corresponding to the elastic element 5. The upper end of the elastic element 5 is placed in the limiting groove 43, and the lower end of the elastic element 5 is sleeved on the limiting post 62, thereby limiting the elastic element 5.

[0057] The water inlet section 2 includes a water inlet ball head 21 and a water inlet component 23. The water inlet ball head 21 is connected to the top of the outer casing 1, and the water inlet component 23 is located inside the outer casing 1. The water outlet end of the water inlet ball head 21 is connected to the water inlet structure (i.e., the water inlet cavity 41 of the water distribution plate 4) through the water inlet component 23. The water inlet component 23 is roughly inverted T-shaped in the front view, with its upper end fitted over the ball head portion of the water inlet ball head 21, and a sealing ring 22 fitting between the two. The lower end of the water inlet component 23 connects to the water inlet cavity 41 of the water distribution plate 4. Therefore, the present invention constitutes a head shower, but is not limited thereto. In other embodiments, the present invention is a handheld shower, etc.

[0058] The working principle of this invention is as follows:

[0059] Its water shut-off status is as follows Figure 12 , Figure 13 As shown, at this time, the descaling rack 6 descends to its lowest position under the combined action of its own weight and the elastic element 5. Each descaling needle 61 of the descaling rack 6 is inserted into the corresponding water outlet hole 91. The first inclined surface 71 of the slider 7 is in complete contact with the second inclined surface 641 of the descaling rack 6. The impact surface 72 of the slider 7 is close to the drain hole 421.

[0060] When water is supplied, water enters the inlet ball head 21, is divided into two streams by the water distribution plate 4, and each stream enters the water distribution chamber 42. The water then exits from the drain hole 421 of the water distribution chamber 42 and impacts the slider 7, causing the slider 7 to slide away from the drain hole 421. Simultaneously, the first inclined surface 71 of the slider 7 pushes against the second inclined surface 641 of the descaling frame 6, causing the descaling frame 6 to rise against its own weight and the force of the elastic element 5. The descaling needle 61 also rises and moves away from the outlet hole 91, causing water to spray out from each outlet hole 91. Figure 14 , Figure 15 As shown in the diagram, the arrows indicate the direction of water flow.

[0061] When the water supply is stopped, the water pressure acting on the slider 7 disappears, and the descaling frame 6 returns to its original position under its own weight and the combined action of the elastic element 5, so that the descaling needle 61 can be inserted into the water outlet 91 again for descaling. As the descaling frame 6 descends, its second inclined surface 641 pushes against the first inclined surface 71 of the slider 7, causing the slider 7 to slide towards the drain hole 421, preparing the slider 7 for the next impact of water flow.

[0062] Because this invention employs a multi-area descaling rack 6 arrangement, each rack is responsible for descaling the corresponding area of ​​the water outlet 91, thus achieving multi-area descaling. Therefore, while the total area of ​​the multiple racks 6 is relatively large, the area of ​​each rack is not excessively large, meeting the precision requirements of injection molding production and ensuring the coaxiality of the descaling needle 61 and the water outlet 91, preventing the needle from jamming and failing. This solves the problem of existing technologies being unable to produce large-area descaling racks. The driving mechanism preferably includes the water distribution plate 4 and multiple movable units, allowing the invention to directly utilize water flow to provide driving force to synchronously move each descaling rack 6. This makes the invention more convenient to use and allows for synchronous movement of multiple racks 6 with a simple structure and fewer parts, making the product easier to make thinner.

[0063] Example 2

[0064] Please see Figures 16-23 As shown, the water outlet device with descaling function of the present invention differs from the above-described embodiment 1 in that: a driving member 20 is installed inside the water distribution chamber 42, and the driving member 20 forms an inclined surface engagement with the slider 7, so that the driving member 20 drives the slider 7 to slide when driven by water flow. Specifically, the slider 7 is provided with a third inclined surface 74, and the bottom of the driving member 20 is provided with a fourth inclined surface 201. The third inclined surface 74 and the fourth inclined surface 201 are in contact and can slide relative to each other. The third inclined surface 74 and the first inclined surface 71 of the slider 7 are located on opposite sides of the slider 7. Since each movable unit includes two sliders 7, the bottom of the driving member 20 is provided with two fourth inclined surfaces 201 to engage with the third inclined surfaces 74 of the two sliders 7 respectively. The two fourth inclined surfaces 201 are arranged opposite to each other at the bottom of the driving member 20. The top periphery of the driving member 20 is in a gap engagement with the periphery of the water distribution chamber 42. The bottom of the water distribution chamber 42 is open, that is, the bottom of the water distribution chamber 42 is not provided with a bottom wall, so that the bottom of the driving member 20 can be exposed and engage with the slider 7.

[0065] The drive component 20 has a water inlet groove 202 on its top and at least one water passage hole 203 communicating with the water inlet groove 202 on its side wall. As the drive component 20 is driven by water flow, the water passage hole 203 gradually protrudes outside the water distribution chamber 42. Specifically, there are two water passage holes 203 on the drive component 20, located on the side of the drive component 20 facing the slider 7 and above the bottom of the drive component 20. The slider 7 also has a water passage groove 73, which is approximately L-shaped.

[0066] The working principle of this invention is as follows:

[0067] Its water shut-off status is as follows Figure 20 , Figure 21As shown, at this time, the descaling rack 6 descends to its lowest position under the combined action of its own weight and the elastic element 5. Each descaling needle 61 of the descaling rack 6 is inserted into the corresponding water outlet hole 91. The first inclined surface 71 of the slider 7 is in complete contact with the second inclined surface 641 of the descaling rack 6. The driving element 20 is in a higher position, and its water passage hole 203 enters the water distribution chamber 42. Its fourth inclined surface 201 is in partial contact with the third inclined surface 74 of the slider 7.

[0068] When water is supplied, water enters the inlet ball head 21 and is divided into two streams by the water distribution plate 4. Each stream enters the water distribution chamber 42 and impacts the sliding drive component 20, causing it to move downwards. The water passage hole 203 of the drive component 20 gradually protrudes from the water distribution chamber 42, allowing water entering the inlet tank of the drive component 20 to drain into the outlet chamber through the water passage hole 203. Simultaneously, the fourth inclined surface 201 of the drive component 20 pushes the third inclined surface 74 of the slider 7, thus pushing the slider 7 to slide. The first inclined surface 71 of the slider 7 then pushes the second inclined surface 641 of the descaling frame 6, causing the descaling frame 6 to rise against its own weight and the force of the elastic element 5. The descaling needle 61 also rises and moves away from the outlet hole 91, causing water to spray out from each outlet hole 91. Figure 22 , Figure 23 As shown in the diagram, the arrows indicate the direction of water flow.

[0069] When the water supply stops, the water pressure acting on the drive unit 20 disappears, and the descaling rack 6 returns to its original position under its own weight and the combined action of the elastic element 5, so that the descaling needle 61 can be inserted into the water outlet 91 again for descaling. As the descaling rack 6 descends, its second inclined surface 641 pushes the first inclined surface 71 of the slider 7, causing the slider 7 to slide. The third inclined surface 74 of the slider 7 pushes the fourth inclined surface 201 of the drive unit 20, causing the drive unit 20 to rise to the initial position, preparing the drive unit 20 for the next impact of the water flow.

[0070] The present invention provides a water outlet device with descaling function. The parts not described herein are the same as or can be implemented using existing technologies.

[0071] The above embodiments are only used to further illustrate a water outlet device with descaling function according to the present invention.
