[0018] 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:

[0019] 1. In Scheme 1 and its preferred embodiments, a water outlet component includes a body, a needle plate, and a reset component.

[0020] The main body is equipped with a water inlet and several water passage holes;

[0021] The needle plate comprises a plate body and several descaling needles protruding from the plate body. The plate body has water passage holes connecting the inlet and outlet holes, and / or a water passage gap connecting the inlet and outlet holes is provided between the plate body and the main body to allow water to pass through. The water passage holes compensate for insufficient water passage in the water passage gap. The needle plate is adapted to move to a first position under hydraulic drive when water enters through the inlet hole, so that the descaling needles are inserted into the outlet holes to remove impurities. Several filter holes are formed between the descaling needles and the hole walls of the outlet holes to perform filtration and rectification functions during use.

[0022] The reset component acts on the plate and the main body respectively at both ends. When the water inlet is stopped, the needle plate moves to the second position so that the descaling needle is further away from the water passage than in the first position. This increases the water passage area of ​​the water passage, and the impurities above the water passage will be discharged with the residual water. This allows the impurities to be discharged without causing blockage, and it is more convenient as there is no need for regular cleaning.

[0023] 2. In Scheme 2 and its preferred embodiments, the main body is also provided with a water outlet hole, and a water straightening channel is provided between the water passage hole and the water outlet hole to prevent the water from flowing directly into the water outlet hole at the bottom, which would cause the water pattern to become chaotic, which would be inconvenient to use and unsightly.

[0024] 3. In Scheme 3 and its preferred embodiments, the rectifying water channel is composed of multiple water channels with different water flow directions, or the rectifying water channel is provided with several rectifying water holes to achieve the function of rectifying the flow. Among them, the rectifying water channel is composed of multiple water channels with different water flow directions, which makes it less prone to accumulation of dirt.

[0025] 4. In Scheme 4 and its preferred embodiments, a filter screen is also included. The filter screen is located in the rectifier channel and has several filter holes and impurity discharge holes. The inner wall size of the filter screen gradually decreases towards the impurity discharge holes, so that under the action of water, impurities are guided down the inner wall of the filter screen and flow to the impurity discharge holes, which facilitates impurity discharge. The filter holes serve the functions of filtration and rectification.

[0026] 5. In Scheme 5 and its preferred embodiments, a filter screen is also included. The main body is also provided with a water outlet. The filter screen is located between the water inlet and the water outlet. The filter screen has several filter holes and impurity discharge holes. The inner wall size of the filter screen gradually decreases along the direction close to the impurity discharge holes, so that under the action of water, impurities are guided down through the inner wall of the filter screen and flow to the impurity discharge holes, which is conducive to impurity discharge. The filter holes play the role of filtration and rectification.

[0027] 6. In Scheme 6 and its preferred embodiments, the water passage hole includes a guide hole and a first hole communicating with the guide hole. The descaling needle is suitable for insertion and withdrawal from the first hole. The guide hole is closer to the plate body than the first hole. The size of the guide hole gradually decreases along the direction close to the first hole to have a certain guiding effect, preventing the descaling needle from being difficult to insert into the first hole, resulting in failure of impurity removal, reducing manufacturing precision and manufacturing cost. Furthermore, under the action of the guide hole, impurities are also easy to flow out of the water passage hole with the residual water.

[0028] 7. In Scheme 7 and its preferred embodiments, the body is provided with a first limiting surface, the needle plate is provided with a hook, the hook is adapted to deform to cross the first limiting surface, and a second limiting surface is provided opposite to the first limiting surface. The reset member is adapted to apply a force to the needle plate to make the second limiting surface approach the first limiting surface, so as to prevent the needle plate from detaching from the body under the action of the reset member.

[0029] 8. In Scheme 8 and its preferred embodiments, the main body is further provided with a water passage hole, which is located around the water passage hole and communicates with the hole wall of the water passage hole to increase the water passage volume and assist in the discharge of impurities in the residual water.

[0030] 9. In Scheme 9 and its preferred embodiments, a sealing ring is also included. The sealing ring is installed on the body and located on the side of the body with the water inlet hole, so as to achieve the sealing effect when the water outlet component is connected with other products, and prevent water leakage at the connection point.

[0031] 10. In Scheme 10 and its preferred embodiments, a water outlet device includes a water passage assembly and the aforementioned water outlet component. The water outlet component is installed on the water passage assembly and connects the water inlet to the water passage of the water passage assembly, thus having the beneficial effects brought about by the aforementioned water outlet component.

[0046] refer to Figures 1-6A water outlet component includes a body 1, a needle plate 2, a reset component 3, a filter screen 4, and a sealing ring 5. This water outlet component can be an aerator, shower head, or other similar product.

[0047] The main body 1 includes a filter component 11, an upper outer shell 12, and a lower outer shell 13.

[0048] refer to Figures 4-6 The filter component 11 is provided with a water inlet 111, a plurality of water passage holes 112, and water through holes 113. Each water passage hole 112 includes a guide hole 1121 and a first hole 1122 communicating with the guide hole 1121. The guide hole 1121 is closer to the plate 22 of the needle plate 2 (described below) than the first hole 1122. The size of the guide hole 1121 gradually decreases along the direction closer to the first hole 1122, while the size of the first hole 1122 remains constant along its water passage direction. The water through holes 113 are located around the water passage holes 112 and communicate with the hole walls of the water passage holes 112. In this embodiment, there are four water through holes 113 evenly surrounding the water passage holes 112. The filter component 11 is also provided with mounting holes 114 around its water passage area (water passage holes 112 and water through holes 113). The filter component 11 is also provided with a first limiting surface 115 facing the lower outer casing 13.

[0049] refer to Figures 5-6 The upper outer shell 12 is fitted onto the outside of the filter component 11. The upper outer shell 12 is elastically engaged with the outer wall of the filter component 11 and with the top of the lower outer shell 13. The upper outer shell 12 is provided with a first water channel 121. The top of the first water channel 121 communicates with the water passage hole 112 and the water through hole 113. The water inlet direction and the water outlet direction of the first water channel 121 intersect each other. In this embodiment, it is in the form of water inlet at the top and water outlet at all four sides. The top is the location of the water inlet hole 111.

[0050] The lower outer casing 13 is provided with a water outlet 133 and a mounting cavity communicating with the water outlet 133. When the lower outer casing 13 is connected to the upper outer casing 12, the mounting cavity is divided into a second water channel 131 and a third water channel 132. Both the second water channel 131 and the third water channel 132 are communicating with the water outlet 133. The water inlet end of the second water channel 131 is connected to the water outlet end of the first water channel 121. The second water channel 131 surrounds the outside of the third water channel 132. When water is discharged, there are two water discharge paths: one is water discharge from the second water channel 131, the third water channel 132, and the water outlet 133 in sequence, and the other is water discharge from the second water channel 131 and the water outlet 133 in sequence. In other embodiments, the water outlet 133, the second water channel 131, and the third water channel 132 may not be provided. In this case, the water passage 112 is used as the water outlet end of the water outlet component. The water flowing out through the water passage 112 directly enters the usage environment for user use.

[0051] In this embodiment, the first waterway 121, the second waterway 131, and the third waterway 132 constitute a rectifying waterway consisting of multiple waterways with different flow directions. This rectifying waterway is located between the water passage 112 and the water outlet 133 and is used for rectification. In other embodiments, the rectifying waterway is provided with several rectifying water holes to achieve rectification; this is prior art and will not be described in detail.

[0052] The filter screen 4 is located between the water passage hole 112 and the water outlet hole 133. Specifically, the filter screen 4 is placed inside the mounting cavity and located in the rectifier water channel. The filter screen 4 is provided with several filter holes and a debris discharge hole 41. The debris discharge hole 41 is located in the middle of the filter screen 4, and the filter holes are arranged around the debris discharge hole 41. The inner wall size of the filter screen 4 gradually decreases along the direction close to the debris discharge hole 41.

[0053] refer to Figure 3 The needle plate 2 has a plate body 22 and a plurality of descaling needles 23 protruding from the plate body 22. A hook 21 is provided around the periphery of the needle plate 2. The hook 21 is adapted to deform when it abuts against the main body 1 and passes through the mounting hole 114 to cross the first limiting surface 115. The hook 21 has a second limiting surface 211 opposite to the first limiting surface 115. When the hook 21 crosses the first limiting surface 115, it returns to its original position, and the second limiting surface 211 is opposite to the first limiting surface 115. The plate body 22 has a water passage hole 221 connecting the water inlet hole 111 and the water passage hole 112, and / or a water passage gap connecting the water inlet hole 111 and the water passage hole 112 is provided between the plate body 22 and the filter component 11 of the main body 1. In this embodiment, there are both water passage holes 221 and water passage gaps. The needle plate 2 is adapted to move to the first position by hydraulic drive when water enters through the inlet hole 111, so that the descaling needle 23 is guided through the guide hole 1121 and inserted into the first hole 1122 of the water passage hole 112, and a plurality of filter holes 6 are formed between the needle plate 2 and the hole wall of the water passage hole 112. In this embodiment, since the descaling needle 23 is inserted into both the guide hole 1121 and the first hole 1122 at the same time, the filter hole 6 is formed by the gap between the hole wall of the guide hole 1121, the hole wall of the first hole 1122 and the descaling needle 23.

[0054] refer to Figures 5-6 The two ends of the reset member 3 act on the plate 22 and the body 1 respectively, so that when the water inlet hole 111 is stopped, the needle plate 2 moves to the second position, so that the descaling needle 23 is further away from the water passage hole 112 than in the first position. In this embodiment, the descaling needle 23 is withdrawn from the first hole 1122. The fact that the descaling needle 23 is further away from the water passage hole 112 than in the first position can be understood as the descaling needle 23 inserting a smaller distance into the water passage hole 112 in the second position compared to the first position, thus increasing the water passage area of ​​the water passage hole 112. In this embodiment, the reset member 3 is a spring; in other embodiments, it can also be rubber, etc. In this embodiment, the reset member 3 is adapted to apply a force to the needle plate 2 to bring the second limiting surface 211 closer to the first limiting surface 115.

[0055] The sealing ring 5 is installed on the body 1 and is located on the side of the body 1 with the water inlet hole 111. In this embodiment, the body 1 is installed on the upper end face of the upper outer shell 12.

[0056] Initially, the needle plate 2 is in the second position under the action of the reset member 3, at which time the descaling needle 23 is withdrawn from the first hole 1122. When water enters through the inlet hole 111, water force acts on the plate body 22, and the needle plate 2 is driven by water force to move to the first position, so that the descaling needle 23 is guided through the guide hole 1121 and inserted into the first hole 1122 of the water passage hole 112 to remove impurities (during use, the impurities will flow out with the water from the outlet hole 133). Several filter holes 6 are formed between the descaling needle 23 and the hole wall of the water passage hole 112 to play a role in filtration and rectification during use. During this process, the reset member 3 stores energy. The water outlet path mainly consists of the inlet hole 111, filter holes 6 (water passage hole 112) and / or water passage hole 113, first water channel 121, second water channel 131, third water channel 132, water passage hole 221 and / or water passage gap, and outlet hole 133.

[0057] When the inlet hole 111 is stopped, the reset member 3 releases energy, causing the needle plate 2 to move to the second position. This allows the descaling needle 23 to be further away from the first hole 1122 of the water passage hole 112 compared to the first position, increasing the water passage area of ​​the water passage hole 112. Impurities above the water passage hole 112 will be discharged with the residual water, thus allowing the impurities to be discharged without causing blockage and eliminating the need for regular cleaning, making it more convenient. The sludge discharge path mainly consists of the inlet hole 111, filter hole 6 (water passage hole 112) and / or water passage hole 113, first water channel 121, second water channel 131, third water channel 132, water passage hole 221, and outlet hole 133.

[0058] Compared with the prior art, this embodiment has the following beneficial effects:

The needle plate 2 has a plate body 22 and several descaling needles 23 protruding from the plate body 22. The plate body 22 has water passage holes 221 communicating with the inlet hole 111 and the through holes 112, and / or a water passage gap communicating with the inlet hole 111 and the through holes 112 is provided between the plate body 22 and the body 1 to allow water to pass through. The water passage holes 221 compensate for insufficient water passage in the water passage gap. The needle plate 2 is adapted to move to a first position when water enters through the inlet hole 111, so that the descaling needles 23 are inserted into the through holes 112 to remove impurities. Several filter holes 6 are formed between the descaling needles 23 and the hole walls of the through holes 112 to perform filtration and rectification during use. The reset member 3 acts on the plate 22 and the body 1 respectively at both ends. When the water inlet hole 111 is stopped, the needle plate 2 moves to the second position so that the descaling needle 23 is further away from the water passage hole 112 than in the first position. This increases the water passage area of ​​the water passage hole 112, and the impurities above the water passage hole 112 will be discharged with the residual water. This allows the impurities to be discharged without causing blockage, and it is more convenient as there is no need for regular cleaning.

[0060] In one exemplary embodiment, the main body 1 is further provided with a water outlet 133. The main body 1 is also provided with a straightening water channel between the water passage 112 and the water outlet 133 to prevent the water from flowing directly into the water outlet 133 at the bottom, which would cause the water pattern to become chaotic, which would be inconvenient to use and unsightly.

[0061] In one exemplary embodiment, the rectifier channel consists of multiple channels with different water flow directions, or the rectifier channel is provided with several rectifier holes to achieve the function of rectification. The fact that the rectifier channel consists of multiple channels with different water flow directions makes it less prone to accumulation of debris.

[0062] In one exemplary embodiment, a filter screen 4 is also included. The filter screen 4 is located in the rectifier channel. The filter screen 4 is provided with a plurality of filter holes and impurity discharge holes 41. The inner wall size of the filter screen 4 gradually decreases along the direction close to the impurity discharge holes 41, so that under the action of water, impurities are guided down through the inner wall of the filter screen 4 and flow to the impurity discharge holes 41, which is conducive to impurity discharge. The filter holes serve the functions of filtration and rectification.

[0063] In one exemplary embodiment, a filter screen 4 is also included. The body 1 is further provided with a water outlet 133. The filter screen 4 is located between the water passage 112 and the water outlet 133. The filter screen 4 is provided with a plurality of filter holes and impurity discharge holes 41. The inner wall size of the filter screen 4 gradually decreases along the direction close to the impurity discharge holes 41, so that under the action of water, impurities are guided down through the inner wall of the filter screen 4 and flow to the impurity discharge holes 41, which is conducive to impurity discharge. The filter holes play the role of filtration and rectification.

[0064] In one exemplary embodiment, the water passage 112 includes a guide hole 1121 and a first hole 1122 communicating with the guide hole 1121. The descaling needle 23 is adapted to be inserted into and withdrawn from the first hole 1122. The guide hole 1121 is closer to the plate 22 than the first hole 1122. The size of the guide hole 1121 gradually decreases along the direction close to the first hole 1122 to have a certain guiding effect, preventing the descaling needle 23 from being difficult to insert into the first hole 1122, resulting in failure of descaling, reducing manufacturing precision and manufacturing cost. Furthermore, under the action of the guide hole 1121, impurities are also easily discharged from the water passage 112 with the residual water.

[0065] In one exemplary embodiment, the body 1 is provided with a first limiting surface 115, the needle plate 2 is provided with a hook 21, the hook 21 is adapted to deform to pass over the first limiting surface 115, and is provided with a second limiting surface 211 opposite to the first limiting surface 115. The reset member 3 is adapted to apply a force to the needle plate 2 to bring the second limiting surface 211 closer to the first limiting surface 115, so as to prevent the needle plate 2 from detaching from the body 1 under the action of the reset member 3.

[0066] In one exemplary embodiment, the body 1 is further provided with a water passage hole 113, which is located around the water passage hole 112 and communicates with the hole wall of the water passage hole 112 to increase the water flow and assist in the discharge of impurities in the residual water.
