Description

Technical Field

[0001] This invention relates to the field of water-dispensing products, specifically to a water-dispensing component and a shower head. Background Technology

[0002] During daily use, the water outlet may become clogged with sediment due to the presence of silt in the water. This affects the water flow. To solve this problem, a filter screen is installed inside the water circuit to filter the water flowing to the outlet and intercept the sediment. Although this method prevents the outlet from becoming clogged by sediment, the filter holes on the screen can still become clogged. Therefore, the screen needs to be disassembled and cleaned to solve the problem. Frequent disassembly can damage the connection structure and increase the frequency of maintenance and the user's workload. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems existing in the prior art or to provide a material basis for overcoming the aforementioned defects or problems existing in the prior art, and to provide a water outlet component and a shower head.

[0017] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means: A water outlet component includes a water passage body and a filter screen. The water passage body has a first water passage chamber, a sand discharge hole, a water passage hole, a second water passage chamber, and a water outlet hole; the first water passage chamber and the sand discharge hole are connected in sequence, and the first water passage chamber, the water passage hole, the second water passage chamber, and the water outlet hole are connected in sequence; the filter screen is placed in the first water passage chamber and covers the water passage hole to prevent sediment from passing directly through the water passage hole, and the filter screen has a plurality of filter holes that connect the water passage hole and the first water passage chamber to achieve the filtration function. Therefore, the water outlet has two water channels. One is a filtration water channel, which connects the first water passage chamber, filter hole, water passage hole, second water passage chamber, and water outlet in sequence. This filters out sediment and improves the cleanliness of the effluent. The filtered sediment adheres to the surface of the filter screen away from the water passage hole or falls into the first water passage chamber, preventing the water outlet from becoming clogged. The other is a sand discharge water channel, which connects the first water passage chamber and sand discharge hole in sequence. This allows the sediment adhering to the surface of the filter screen or the sediment in the first water passage chamber to be discharged through the sand discharge hole with the water flow. This removes impurities from the filter screen and prevents sediment from clogging the filter holes, ensuring normal water output from the water outlet. At the same time, this cleaning method is achieved by hydraulic power, eliminating the need for frequent disassembly of the main water channel body to clean the filter screen, which is more convenient and extends the service life of the water outlet. By actively blocking the pressure difference and reconstructing the flow channel, all incoming water is forced to impact the water-facing surface of the filter screen at a high flow rate, thereby 'stripping off the attached sediment in situ, carrying it, and discharging it in a directional manner'. This breaks through the limitations of traditional filter screens that rely on manual disassembly and washing or static self-cleaning, and achieves a truly one-button, tool-free, consumable-free, closed-loop internal sediment discharge function.

[0025] The main waterway includes a water passage body 1, a first sealing element 2, a second sealing element 3, a water distribution element 4, and an elastic element 5.

[0026] The water passage body 1 includes a first shell 11, a second shell 12, a water distribution plate 13, a fixing ring 14, and a mounting bracket 15.

[0027] refer to Figure 9 The first housing 11 includes the water outlet portion of the shower head. The first housing 11 has a clearance hole 111 and a mounting cavity 112 communicating with the clearance hole 111. The mounting cavity 112 extends along a first direction 8 and is used for mounting the water distribution plate 13, the rotary disc 71 of the switching component 7, the elastic element 5, the first seal 2, the second seal 3, and the retaining ring 14. (Referring to...) Figure 10 The retaining ring 14 is engaged with the mounting cavity 112 to achieve fixation. (Reference) Figure 9 The clearance hole 111 extends in a direction perpendicular to the first direction 8, and its transverse cross-section is arc-shaped, for allowing the connecting rod 72 of the switching member 7 to extend and rotate. (See reference) Figure 11 The clearance hole 111 is provided with a first limiting surface 1111 and a second limiting surface 1112. (Reference) Figure 7 , Figure 9The first shell 11 is also provided with a water outlet 113 and a sand discharge hole 114, which are used for normal water discharge and impurity removal, respectively.

[0028] The second shell 12 is fitted onto the first shell 11 and is detachably connected to the first shell 11. In this embodiment, the second shell 12 is threadedly connected to the first shell 11. (See reference) Figure 2 and Figure 9 The second shell 12 is provided with a handle part 121. The handle part 121 is provided with a water passage cavity 1211 and a water inlet hole 1212. One end of the water passage cavity 1211 is connected to the water inlet hole 1212, and the other end is open on the surface of the second shell 12.

[0029] refer to Figure 4 The mounting bracket 15 is T-shaped for mounting the filter screen 6. The mounting bracket 15 has a column 151 and a contact portion 152 protruding radially outward along the column 151. The column 151 has a water passage hole 1511 extending perpendicular to the first direction 8 and a second water passage cavity 1512 extending along the first direction 8. The contact portion 152 has a water passage hole 1521 extending along the first direction 8. (Reference) Figure 7 The mounting bracket 15 is installed inside the water passage cavity 1211, so that the column 151 and the water passage cavity 1211 enclose to form the first water passage cavity 16. After the second shell 12 and the first shell 11 are installed, the column 151 abuts against the fixing ring 14, the abutting part 152 abuts against the bottom end of the water passage cavity 1211, and the water passage hole 1521 connects the water inlet hole 1212 and the first water passage cavity 16.

[0030] refer to Figure 3 The water distribution plate 13 is provided with a third water distribution hole 131 and a fourth water distribution hole 132 extending along the first direction 8. The water distribution plate 13 is provided with a mounting post 133, which extends along the first direction 8. The water distribution plate 13 is fixedly connected to the first shell 11.

[0031] refer to Figure 5 The water distribution component 4 is provided with an installation groove 41, and the installation column 133 extends into the installation groove 41 after passing through the installation hole 712 of the switching component 7. The water distribution component 4 is provided with a first water distribution hole 42 and a second water distribution hole 43, for reference. Figure 8 The first water distribution hole 42 connects the first water passage cavity 16 and the sand discharge hole 114, for reference. Figure 7 The second water distribution hole 43 connects the second water passage chamber 1512 and the water outlet hole 113. (Reference) Figure 7 The water distribution component 4 has a water-passing hole in the middle. The water outlet end of the hole is connected to the second water distribution hole 43, and the water inlet end is connected to the second water passage cavity 1512. The middle part of the water distribution component 4 is suitable for insertion into the second water passage cavity 1512.

[0032] The filter screen 6 is located inside the handle part 121. Preferably, the filter screen 6 is sleeved on the column 151 and placed in the first water passage cavity 16. The filter screen 6 covers the water passage hole 1511. The filter screen 6 is provided with a plurality of filter holes, which are connected to the water passage hole 1511 and the first water passage cavity 16.

[0033] The switching element 7 is installed on the main body of the water system and moves relative to the main body of the water system so that the first water passage cavity 16 communicates only with the sand discharge hole 114 or only with the water outlet hole 113. In this embodiment, the switching element 7 is rotatably connected to the main body of the water system about an axis parallel to the first direction 8. Specifically, refer to... Figure 6 , Figure 10 The switching component 7 includes a turntable 71, a connecting rod 72, and a knob 73. The turntable 71 is installed in the mounting cavity 112 and has a water passage hole 711 extending along the first direction 8. When the turntable 71 rotates, the water passage hole 711 communicates with the first water distribution hole 42 or the second water distribution hole 43. The two ends of the turntable 71 abut against the water distribution plate 13 and the water distribution component 4, respectively. The middle part of the turntable 71 has a mounting hole 712 for the mounting post 133 to pass through. The turntable 71 also has a insertion hole 713 extending in a direction perpendicular to the first direction 8. When the water passage hole 711 communicates with the third water distribution hole 131, the third water distribution hole 131 is connected to the water passage hole 711 and the sand discharge hole 114; when the water passage hole 711 communicates with the fourth water distribution hole 132, the fourth water distribution hole 132 is connected to the water passage hole 711 and the water outlet hole 113.

[0034] The connecting rod 72 passes through the clearance hole 111 and is connected to the turntable 71 and the knob 73 to prevent rotation and rotate synchronously. The connecting rod 72 is adapted to abut against the first limiting surface 1111 and the second limiting surface 1112. Specifically, the connecting rod 72 passes through the clearance hole 111, thereby abutting against the first limiting surface 1111 and the second limiting surface 1112. When the switching member 7 abuts against the first limiting surface 1111, the water passage hole 711 communicates with the first water distribution hole 42. When the switching member 7 abuts against the second limiting surface 1112, the water passage hole 711 communicates with the second water distribution hole 43.

[0035] refer to Figure 2 , Figure 10The knob 73 is fitted onto the outer side of the main body of the water system. The knob 73 has a socket 731 extending along the first direction 8. The socket 731 opens onto the surface of the knob 73 along the first direction 8. During installation, the knob 73 is fitted onto the outer wall of the first housing 11 and slides along the first direction 8, so that the connecting rod 72 is inserted into the socket 731 through the opening of the socket 731 and engages with the socket 731 to prevent rotation. At the same time, the other end of the connecting rod 72 is inserted into the insertion hole 713 of the turntable 71 to engage with the turntable 71 to prevent rotation, thereby achieving synchronous rotation of the three. Of course, in order to make the connection between the knob 73 and the connecting rod 72 more stable, it is preferable that an elastic protrusion is provided in the socket 731. After the connecting rod 72 passes over the elastic protrusion, it is clamped between the elastic protrusion and the socket 731 along the first direction 8, which further increases the fixing strength. Based on the socket 731, the connecting rod 72 only needs to overcome the deformation force of the elastic protrusion to achieve installation. Compared with the method of only setting the elastic protrusion, the installation is easier and can also achieve the anti-rotation effect.

[0036] refer to Figure 7 The first shell 11 and the second shell 12 are clamped on both sides of the knob 73 along the first direction 8, thereby preventing the knob 73 from disengaging from the connecting rod 72.

[0037] The first sealing element 2 is arranged around the first water distribution hole 42 and the second water distribution hole 43. The number of the first sealing element 2 is one or more, so as to seal the first water distribution hole 42 and the second water distribution hole 43 respectively.

[0038] The second seal 3 is arranged around the third water distribution hole 131 and the fourth water distribution hole 132. Similarly, the number of the second seal 3 is one or more.

[0039] The two ends of the elastic element 5 act on the fixing ring 14 of the water passage body 1 and the water distribution element 4, respectively, and apply a force to the water distribution element 4 to make it move towards the switching element 7, so that the first sealing element 2 is clamped between the switching element 7 and the water distribution element 4, and the second sealing element 3 is clamped between the switching element 7 and the water distribution plate 13 of the water passage body 1. In this embodiment, the elastic element 5 is a spring.

[0040] When in use, rotating the switching component 7 to the water outlet mode causes the water inlet 1212, water passage 1521, first water passage 16, filter hole of filter screen 6, water passage 1511, second water passage 1512, second water distribution hole 43 of water distribution component 4, water passage 711 of switching component 7, fourth water distribution hole 132, and water outlet 113 to be connected in sequence, so as to achieve normal filtered water outlet. The sediment will be blocked by filter screen 6 and will adhere to the surface of filter screen 6 away from water passage 1511 or fall into the first water passage 16.

[0041] When the switching component 7 is rotated to the sand discharge mode, the second water distribution hole 43 is no longer connected to the water passage hole 711, and the water outlet hole 113 cannot discharge water. At this time, the water inlet hole 1212, the water passage hole 1521, the first water passage cavity 16, the first water distribution hole 42 of the water distribution component 4, the water passage hole 711 of the switching component 7, the third water distribution hole 131, and the sand discharge hole 114 are connected in sequence, and the mud and sand attached to the surface of the filter screen 6 or the mud and sand in the first water passage cavity 16 are discharged through the sand discharge hole 114 with the water flow.

[0042] In this embodiment, there are two water passage holes 711 arranged opposite each other, two first water distribution holes 42 arranged opposite each other, two second water distribution holes 43 arranged opposite each other, two third water distribution holes 131 arranged opposite each other (corresponding one-to-one with the first water distribution holes 42), and two fourth water distribution holes 132 arranged opposite each other (corresponding one-to-one with the second water distribution holes 43). Of course, in other embodiments, this number is not limited.

[0043] Compared with the prior art, this embodiment has the following beneficial effects: In one exemplary embodiment, a water outlet includes a water channel body and a filter screen 6.

[0044] The main waterway is provided with a first water passage chamber 16, a sand discharge hole 114, a water passage hole 1511, a second water passage chamber 1512, and a water outlet hole 113; the first water passage chamber 16 and the sand discharge hole 114 are connected in sequence. The first water passage chamber 16, the water passage hole 1511, the second water passage chamber 1512 and the water outlet hole 113 are connected in sequence; The filter screen 6 is placed inside the first water passage chamber 16 and covers the water passage hole 1511 to prevent mud and sand from passing directly through the water passage hole 1511. The filter screen 6 is provided with several filter holes, which are connected to the water passage hole 1511 and the first water passage chamber 16 to achieve the filtration function.

[0045] Therefore, the water outlet has two water channels. One is a filtration water channel that connects the first water passage chamber 16, filter hole, water passage hole 1511, second water passage chamber 1512, and water outlet hole 113 in sequence, thereby filtering out sediment and improving the cleanliness of the water. The filtered sediment adheres to the surface of the filter screen 6 away from the water passage hole 1511 or falls into the first water passage chamber 16, preventing the water outlet hole 113 from becoming clogged. The other is a sand discharge water channel that connects the first water passage chamber 16 and sand discharge hole 114 in sequence, which is used to discharge the sediment on the surface of the filter screen 6 or the sediment in the first water passage chamber 16 with the water flow through the sand discharge hole 114, thereby removing impurities from the filter screen 6 and preventing sediment from clogging the filter hole, ensuring normal water output from the water outlet hole 113. At the same time, this cleaning method is achieved by hydraulic power, eliminating the need for frequent disassembly of the main water channel body to clean the filter screen 6, which is more convenient and extends the service life of the water outlet. The pressure difference and flow channel reconstruction formed by active blocking force all the incoming water to impact the water-facing surface of the filter screen 6 at a high flow rate, thereby removing the attached sediment in situ, carrying it, and discharging it in a directional manner. This breaks through the limitations of traditional filter screen 6 which relies on manual disassembly and washing or static self-cleaning, and realizes a truly one-button, tool-free, consumable-free, closed-loop internal sediment discharge function.

[0046] In one exemplary embodiment, a switching component 7 is further included. The switching component 7 is installed on the main body of the water system and moves relative to the main body of the water system so that the first water passage 16 is connected only to the sand discharge hole 114 or only to the water outlet hole 113. On the one hand, the switching component 7 installed on the main body of the water system can be directly operated to switch the water system without operating the external water system switching components of the water outlet, which is more convenient. On the other hand, being connected to only one water system ensures the water volume and water pressure when water is discharged from the water outlet hole 113, which is convenient for bathing, and the water pressure and water volume when water is discharged from the sand discharge hole 114, which ensures the sand discharge effect.

[0047] In one exemplary embodiment, the main body of the water system is provided with a first water distribution hole 42 and a second water distribution hole 43. The first water distribution hole 42 connects to the first water passage chamber 16 and the sand discharge hole 114, and the second water distribution hole 43 connects to the second water passage chamber 1512 and the water outlet hole 113. The switching component 7 is provided with a water passage hole 711. The switching component 7 moves relative to the main body of the water system, so that the water passage hole 711 connects with the first water distribution hole 42 or the second water distribution hole 43, that is, the first water passage chamber 16, the first water distribution hole 42, the water passage hole 711, and the sand discharge hole 114 are connected in sequence to achieve sand discharge, or the first water passage chamber 16, the filter hole of the filter screen 6, the water passage hole 1511, the second water passage chamber 1512, the second water distribution hole 43, the water passage hole 711, and the water outlet hole 113 are connected in sequence to achieve water discharge.

[0048] In one exemplary embodiment, the water passage body 1 includes a water distribution plate 13, which is provided with a third water distribution hole 131 and a fourth water distribution hole 132. By setting the water distribution plate 13, the corresponding water hole settings can be realized.

[0049] In one exemplary embodiment, the water-passing body 1 includes a second shell 12 and a mounting bracket 15. The second shell 12 is provided with a water passage cavity 1211 and a water inlet hole 1212. One end of the water passage cavity 1211 communicates with the water inlet hole 1212, and the other end opens onto the surface of the second shell 12. The mounting bracket 15 is provided with a column 151 and an abutment portion 152 protruding radially outward along the column 151. The column 151 is provided with a water passage hole 1511 and a second water passage cavity 1512. The abutment portion 152 is provided with a water passage hole 1521 extending along a first direction 8. Since the water passage hole 1521 is located radially protruding from the column 1511... The abutment portion 152 of 51 is designed to form a water hole that is not directly connected to the water passage hole 1511 or the second water passage cavity 1512, which facilitates the design of the water passage. The mounting bracket 15 is installed in the water passage cavity 1211 to realize the installation and protection of the mounting bracket 15, and to make the column 151 and the water passage cavity 1211 enclose to form the first water passage cavity 16. Since the mounting bracket 15 is installed in the water passage cavity 1211, the water passage hole 1511 is also connected to the first water passage cavity 16. The water passage hole 1521 connects the first water passage cavity 16 and the water inlet hole 1212. It is manufactured separately to form the corresponding water passage.

[0050] In one exemplary embodiment, the switching component 7 is rotatably connected to the water channel body about an axis parallel to the first direction 8, so that the water passage 711 is connected to the first water distribution hole 42 or the second water distribution hole 43. The switching is achieved by rotation, which is less likely to be accidentally touched. Moreover, the structure of rotation switching does not protrude on the outer surface compared with the structure of pressing switching, which is better in appearance.

[0051] In one exemplary embodiment, since water is only discharged through the water passage 711 connected to the first water distribution hole 42 and the second water distribution hole 43, to prevent water leakage from the inlet and outlet ends of the water passage 711, which would cause cross-flow between the two water paths, the water path body includes a water passage body 1, a first sealing element 2, a second sealing element 3, a water distribution element 4, and an elastic element 5. The water passage body 1 is provided with a first water passage cavity 16, a sand discharge hole 114, a water passage hole 1511, a second water passage cavity 1512, and a water outlet hole 113; the water distribution element 4 is provided with a first water distribution hole 42 and a second water distribution hole 43, which correspond to the water passage holes. At the water inlet end of 711, the first sealing element 2 is arranged around the first water distribution hole 42 and the second water distribution hole 43, thereby achieving a seal at the water inlet end of the water passage hole 711; the water passage body 1 is provided with a third water distribution hole 131 and a fourth water distribution hole 132. The third water distribution hole 131 is connected to the water passage hole 711 and the sand discharge hole 114, and the fourth water distribution hole 132 is connected to the water passage hole 711 and the water outlet hole 113. The third water distribution hole 131 and the fourth water distribution hole 132 correspond to the water outlet end of the water passage hole 711. The second sealing element 3 is arranged around the third water distribution hole 131 and the fourth water distribution hole 132, thereby achieving a seal at the water outlet end of the water passage hole 711. The two ends of the elastic element 5 act on the water passage body 1 and the water distribution element 4 respectively, and apply a force to the water distribution element 4 so that it is directed toward the switching element 7, so that the first sealing element 2 is clamped between the switching element 7 and the water distribution element 4, and the second sealing element 3 is clamped between the switching element 7 and the water passage body 1. Through the elastic force of the elastic element 5, the first sealing element 2 and the second sealing element 3 are deformed and tightly attached to the corresponding parts, thereby improving the sealing effect. At the same time, under slight shaking, the force of the elastic element 5 can keep the first sealing element 2 and the second sealing element 3 in a sealed state or restore them to a sealed state to prevent water leakage.

[0052] In one exemplary embodiment, the water passage 1 is provided with a mounting post 133, the switching component 7 is provided with a mounting hole 712, and the water distribution component 4 is provided with a mounting groove 41. The mounting post 133 extends into the mounting groove 41 after passing through the mounting hole 712, so that the water passage 1, the switching component 7 and the water distribution component 4 are in a stable position along the direction perpendicular to the first direction 8 and will not generate relative movement, thereby ensuring the rotation accuracy of the switching component 7 and the switching effect after rotation (ensuring the alignment accuracy of the water passage hole 711 and each water distribution hole).

[0053] In one exemplary embodiment, the water channel body is provided with a first limiting surface 1111 and a second limiting surface 1112. When the switching member 7 abuts against the first limiting surface 1111, the water passage 711 communicates with the first water distribution hole 42. When the switching member 7 abuts against the second limiting surface 1112, the water passage 711 communicates with the second water distribution hole 43. By setting the limiting position, rapid switching can be achieved and the switching can be ensured to be in place.

[0054] In one exemplary embodiment, the switching component 7 includes a turntable 71, a connecting rod 72, and a knob 73. The water circuit body is provided with a clearance hole 111 and a mounting cavity 112 communicating with the clearance hole 111. The clearance hole 111 is provided with a first limiting surface 1111 and a second limiting surface 1112. The connecting rod 72 passes through the clearance hole 111 and is connected to the turntable 71 and the knob 73 to prevent rotation, so as to achieve synchronous rotation. The connecting rod 72 is adapted to abut against the first limiting surface 1111 and the second limiting surface 1112 to achieve corresponding limiting. The turntable 71 is installed in the mounting cavity 112 to protect the main components of the corresponding switching. The turntable 71 is provided with a water passage hole 711 for water passage. The knob 73 is sleeved on the outside of the water circuit body, and the external knob 73 is convenient for operation.

[0055] In one exemplary embodiment, the water system body includes a first shell 11 and a second shell 12. A turntable 71 has a insertion hole 713 extending in a direction perpendicular to a first direction 8, and a connecting rod 72 is adapted to be inserted into the insertion hole 713. A knob 73 has an insertion hole 731 extending in the first direction 8, opening onto the surface of the knob 73 along the first direction 8. During installation, the knob 73 is adapted to slide along the first direction 8 to allow the connecting rod 72 to be inserted into the insertion hole 731. This method ensures a non-rotating connection even when the turntable 71, connecting rod 72, and knob 73 are all rigid components, facilitating installation and improving strength. The first shell 11 and the second shell 12 are detachably connected and clamped on both sides of the knob 73 along the first direction 8, thereby preventing the knob 73 from shaking along the first direction 8 and causing the connecting rod 72 to exit the insertion hole 731.

[0056] In one exemplary embodiment, the water channel body is provided with a column 151, the column 151 is provided with a water passage hole 1511 and a second water passage cavity 1512, and the filter screen 6 is sleeved on the column 151, thereby restricting the position of the filter screen 6 and preventing positional changes that would prevent the water flowing through the water passage hole 1511 from being filtered.

[0057] In one exemplary embodiment, a shower head includes the aforementioned water outlet component. The shower head has a handle portion 121, and a filter screen 6 is located inside the handle portion 121. The handle portion 121 is used for gripping and water flow. Installing the filter screen 6 at the handle portion 121 facilitates the design of complex water circuit structures in the shower head's water outlet section, thereby improving the water flow effect.
