The air outlet end of the air inlet channel is located between the water inlet and the water outlet holes and is connected with the water outlet cavity. The air inlet channel is suitable for taking in air when water is taken in by the water inlet. When the gas bursts in the water outlet cavity, micro vibration is generated to reduce the adhesion of impurities in the water outlet cavity, so that impurities in the non-working area of ​​the descaling needle can be discharged without causing accumulation.

[0026] The needle plate is provided with a plate body and a descaling needle protruding from the plate body. The needle plate is located in the water outlet cavity.

[0027] The two ends of the reset member act on the plate body and the main body respectively. When the needle plate is in the first position, the reset member stores energy. When the water inlet stops water, the needle plate moves to the second position, so that the descaling needle is farther away from the water outlet than in the first position, so that the water flow area of ​​the water outlet becomes larger, and impurities above the water outlet will be discharged with the residual water, so that the impurities can be discharged without causing blockage, and there is no need for regular cleaning, which is more convenient.

[0028] 2. Option 2 and its preferred embodiment also include a filter screen, which is provided with a plurality of filter holes and is located in the air inlet passage. By utilizing the thickness of the filter screen itself, the thickness of the air inlet passage can be accurately determined during assembly, thereby preventing other substances from entering and causing blockage of the air inlet passage. The filter screen can also cut the air during inhalation to form tiny bubbles that are more easily broken.

[0029] 3. In scheme three and its preferred embodiment, a tapered section with a gradually decreasing water flow area is provided between the water inlet and the air outlet of the air inlet channel to generate negative pressure when water flows (the tapered section can accelerate the water flow speed and generate negative pressure through the Bernoulli principle) to realize air intake in the air inlet channel.

[0030] 4. In scheme 4 and its preferred embodiments, the water outlet hole includes a guide hole and a first hole connected to the guide hole. The guide hole is closer to the plate body than the first hole. The size of the guide hole gradually decreases in the direction approaching the first hole. The descaling needle is suitable for inserting into and withdrawing from the first hole to have a certain guiding effect, thereby preventing the descaling needle from being difficult to insert into the first hole, resulting in impurity removal failure, and reducing manufacturing accuracy and manufacturing cost. In addition, under the action of the guide hole, impurities are also easy to flow out of the water outlet hole along with residual water.

[0031] 5. In the fifth scheme and its preferred embodiment, a rectifying water channel is provided between the outlet end of the air inlet channel and the water outlet hole, and the rectifying water channel is composed of a plurality of water channels with different water flow directions to achieve the effect of rectifying, and is less likely to accumulate impurities, preventing impurities from failing to reach the water outlet hole and failing to be discharged. Alternatively, the rectifying water channel is provided with a plurality of rectifying holes to achieve the effect of rectifying and prevent the water pattern from being chaotic.

[0032] 6. Option 6 and its preferred embodiment further include a sealing ring, which is installed on the main body and located on the side of the main body with the water inlet to achieve a sealing effect when the water outlet is connected to other products to prevent water leakage at the connection point.

[0034] 8. In scheme eight and its preferred embodiment, the water outlet cavity is further provided with a water outlet through hole, which is located around the water outlet hole and connected with the hole wall of the water outlet hole to increase the water output and assist in discharging impurities under residual water.

[0035] 9. In the ninth solution and its preferred embodiment, a water hole connecting the water inlet and the water outlet is provided on the plate body and / or a water gap connecting the water inlet and the water outlet is provided between the plate body and the cavity wall of the water outlet cavity to achieve water flow. If both are provided, the water flow rate can be increased. The water hole is also used for impurities to pass through.

[0036] 10. In scheme 10 and its preferred embodiment, the air inlet channel has a portion whose air flow size gradually decreases along the direction close to the air outlet end of the air inlet channel, so that the size of the bubbles entering the water outlet cavity is smaller and easier to break.

[0037] 11. In scheme 11 and its preferred embodiments, a water hole connecting the water inlet and the water outlet is provided on the plate body. When the needle plate is in the first position, a water gap connecting the water inlet and the water outlet is provided between the plate body and the wall of the water outlet cavity. When it is in the second position, the water gap is closed to prevent debris from clogging the water gap, resulting in the inability to pass water through the water gap, or the needle plate is not easily slid by water force.

[0038] 12. In Scheme 12 and its preferred embodiment, no filter screen is provided at the water inlet, which can ensure that impurities directly enter the water outlet and are then discharged through the descaling needle and water flow without the need for cleaning.

[0039] 13. In the thirteenth scheme and its preferred embodiment, the main body includes a shell, and a first air suction component and a second air suction component mounted on the shell.

The second surface faces the first surface, and the size of the second conical surface gradually decreases along the direction away from the second surface. The first surface and the second surface are enclosed to form an enlarged section with a gradually increasing air flow size, so as to have a larger air flow volume. The first conical surface and the second conical surface are enclosed to form an air passage with a gradually decreasing air flow size. The air inlet, the enlarged section, and the air passage are connected in sequence to form an air inlet channel. The air flow size of the air passage is gradually reduced to accelerate the air flow and make the size of the bubbles entering the water outlet cavity smaller and easier to break.

[0040] 14. In Scheme 14 and its preferred embodiment, the air outlet end of the air inlet channel is closer to the water inlet than the needle plate, so that impurities whose adhesion is reduced due to the air inlet channel can flow to the needle plate and be discharged with the assistance of the needle plate.

[0064] The filter screen 4 is sleeved outside the first conical surface 114 of the first air intake component 11, and the filter screen 4 is provided with a plurality of filter holes. The filter screen 4 is located in the air passage 162 of the enlarged section 161.

[0065] The upper shell 13 is provided with an air inlet hole 131, and the air inlet hole 131, the enlarged section 161, and the air passage 162 are connected in sequence to form the air inlet channel 16. The air inlet hole 131 is the air inlet end of the air inlet channel 16, and the air outlet end of the air passage 162 is the air outlet end of the air inlet channel 16, and the air outlet end of the air inlet channel 16 is closer to the water inlet 111 relative to the needle plate 2. The upper shell 13 is sleeved on the outside of the first air suction component 11 and the second air suction component 12. The upper shell 13 is provided with a first water channel 132, and the water inlet end of the first water channel 132 is connected to the tapered section 112. The water inlet direction and the water outlet direction of the first water channel 132 intersect with each other. In this embodiment, water is inletted from the top and water is discharged in the circumferential direction.

[0066] refer to Figure 3 , Figure 5 , Figure 6 The lower shell 14 is provided with a plurality of water outlet holes 141, water outlet through holes 142 and an installation cavity connected to both the water outlet holes 141 and the water outlet through holes 142. The installation cavity is open at the top and connected to the water outlet holes 141 and the water outlet through holes 142 at the bottom, wherein the top is the position where the water inlet 111 is located. The installation cavity is provided with a first limiting surface 143 facing the water outlet hole 141. When the lower shell 14 is connected to the bottom of the upper shell 13, the installation cavity is divided into a second water channel 144 and a third water channel 145, the second water channel 144 is connected to the water outlet end of the first water channel 132, and the second water channel 144 surrounds the outer side of the third water channel 145. The second water channel 144 and the third water channel 145 are both connected to the water outlet hole 141. The water outlet hole 141 includes a guide hole 1411 and a first hole 1412 connected to the guide hole 1411. The size of the guide hole 1411 gradually decreases in the direction close to the first hole 1412. The water outlet through holes 142 are located around the water outlet hole 141 and communicated with the hole wall of the water outlet hole 141 . In this embodiment, there are four water outlet through holes 142 surrounding the water outlet hole 141 .

[0067] The water inlet 111, the tapered section 112, the first water channel 132, the second water channel 144, the third water channel 145, and the water outlet hole 141 enclose a water outlet cavity 15. The first water channel 132, the second water channel 144, and the third water channel 145 form a rectifying water channel consisting of a plurality of water channels with different water flow directions, and the rectifying water channel is located between the air outlet end of the air inlet channel 16 and the water outlet hole 141. In other embodiments, the rectifying water channel can also be configured to be formed by a plurality of rectifying holes to achieve the purpose of rectification. After the main body 1 is installed, the air outlet end of the air inlet channel 16 is located between the water inlet 111 and the water outlet hole 141. In this embodiment, the air outlet end of the air inlet channel 16 is located between the first water channel 132 and the tapered section 112 and is connected to the water outlet cavity 15. The tapered section 112 is located between the water inlet 111 and the air outlet end of the air inlet channel 16. The air inlet channel 16 is suitable for taking in air when water enters the water inlet 111, and bubbles burst in the water to form micro vibrations to reduce the adhesion of impurities.

[0068] The needle plate 2 is provided with a plate body 21 and a plurality of descaling needles 22 protruding from the plate body 21 . A clamping portion 211 is provided on the periphery of the needle plate 2 . The clamping portion 211 or the lower shell 14 of the main body 1 is suitable for deformation so that the clamping portion 211 passes over the first limiting surface 143 . The clamping portion 211 is provided with a second limiting surface 2111 opposite to the first limiting surface 143 . The plate body 21 is provided with a water hole 212 connecting the water inlet 111 and the water outlet hole 141, and / or a water gap 7 connecting the water inlet 111 and the water outlet hole 141 is provided between the plate body 21 and the lower shell 14 of the main body 1. In this embodiment, there are both water holes 212 and water gap 7. Moreover, when the needle plate 2 is in the first position, a water gap 7 connecting the water inlet 111 and the water outlet hole 141 is provided between the plate body 21 and the cavity wall of the water outlet cavity 15. The water gap 7 is formed by the space between the first limiting surface 143 and the second limiting surface 2111, and the space between the circumference of the plate body 21 and the side wall of the water outlet cavity 15. When in the second position, the first limiting surface 143 and the second limiting surface 2111 are in contact with each other, so that the water gap 7 is closed.

[0069] The guide hole 1411 is closer to the plate body 21 than the first hole 1412. The needle plate 2 is adapted to move between the first position and the second position. When water enters the water inlet 111, the needle plate 2 is adapted to be driven by hydraulic force to move to the first position, so that the descaling needle 22 is guided through the guide hole 1411 to be inserted into the first hole 1412 of the water outlet hole 141, and a plurality of filter holes 6 are formed between the hole wall of the guide hole 1411, the hole wall of the first hole 1412 and the outer wall of the descaling needle 22. When in the second position, the needle plate 22 exits the first hole 1412 to facilitate impurities removal.

[0070] The two ends of the reset member 3 act on the plate body 21 and the main body 1 respectively, so that when the water inlet 111 stops water, the needle plate 2 moves to the second position, so that the descaling needle 22 is further away from the water outlet 141 than when it is in the first position. So that the descaling needle 22 is further away from the water outlet 141 than when it is in the first position, it can be understood that the descaling needle 22 is inserted into the water outlet 141 at a smaller distance in the second position than in the first position, so that the water flow area of ​​the water outlet 141 becomes larger. In this embodiment, the reset member 3 is a spring, and in other embodiments, it can also be rubber or the like.

[0071] The sealing ring 5 is mounted on the body 1 and is located on a side of the body 1 having the water inlet 111 . In this embodiment, the body 1 is mounted on the upper end surface of the first air suction component 11 .

[0072] Initially, the needle plate 2 is located at the second position under the action of the reset member 3, the first limit surface 143 and the second limit surface 2111 are against each other, the water gap 7 is closed, and the descaling needle 22 withdraws from the first hole 1412. When water enters the water inlet 111, the hydraulic force acts on the plate body 21, and the needle plate 2 is driven by the hydraulic force to move to the first position, so that the descaling needle 22 is inserted into the first hole 1412 of the water outlet 141 to achieve the effect of removing impurities (during use, the impurities will flow out of the water outlet 141 with water), and a plurality of filter holes 6 are formed between the descaling needle 22 and the hole wall of the water outlet 141 to play a role of filtering and rectifying when in use. In this process, the reset member 3 stores energy. At the same time, due to the acceleration of the tapered section 112, negative pressure is generated in the water outlet chamber 15. Under the action of atmospheric pressure, the air inlet channel 16 begins to take in air. The air is cut into smaller pieces after passing through the filter screen 4, so that it is easier to explode in the water to form micro-vibration to reduce the adhesion of impurities. Impurities that cannot be removed by the descaling needle 22 in the previous round will also stay above the water outlet hole 141. When the water is turned on next time, the descaling needle 22 will move down and bring out these impurities again, or these impurities are more easily brought out under the action of residual water. The waterway path is that water flows out from the water inlet 111, the tapered section 112, the first water channel 132, the second water channel 144, the water gap 7, the filter hole 6 and / or the water outlet hole 142 in sequence, or water flows out from the water inlet 111, the tapered section 112, the first water channel 132, the second water channel 144, the water hole 212, the filter hole 6 and / or the water outlet hole 142 in sequence.

[0073] When the water inlet 111 stops water, the reset member 3 releases energy to move the needle plate 2 to the second position, so that the descaling needle 22 is further away from the first hole 1412 of the water outlet 141 than in the first position, so that the water flow area of ​​the water outlet 141 becomes larger, and the impurities above the water outlet 141 will be discharged with the residual water, so that the impurities can be discharged. Specifically, at this time, the first limit surface 143 and the second limit surface 2111 are offset, and the water flow gap 7 is closed. The impurities flow from the water inlet 111 to the water through hole 212 and then flow out from the water outlet 141 and / or the water outlet through hole 142. Impurities will not cause blockage, and regular cleaning is not required, which is more convenient.

[0074] Compared with the prior art, this embodiment has the following beneficial effects:

[0075] In an exemplary embodiment, a water outlet component includes a main body 1 , a needle plate 2 and a reset component 3 .

[0076] The body 1 is provided with a water outlet chamber 15 and an air inlet channel 16. The water outlet chamber 15 is provided with a water inlet 111 and a plurality of water outlet holes 141. The air outlet end of the air inlet channel 16 is located between the water inlet 111 and the water outlet holes 141 and is communicated with the water outlet chamber 15. The air inlet channel 16 is suitable for taking in air when water enters the water inlet 111. When the gas bursts in the water outlet chamber 15, micro vibration will be generated to reduce the adhesion of impurities in the water outlet chamber 15, so that impurities in the non-working area of ​​the descaling needle can be discharged without causing accumulation.

[0077] The needle plate 2 is provided with a plate body 21 and a descaling needle 22 protruding from the plate body 21. The needle plate 2 is located in the water outlet chamber 15. The needle plate 2 is adapted to be driven by hydraulic force to move to the first position when water enters the water inlet 111, so that the descaling needle 22 is inserted into the water outlet hole 141, thereby achieving the function of discharging impurities in the water outlet hole 141. At this time, a plurality of filter holes 6 are formed between the descaling needle 22 and the hole wall of the water outlet hole 141, so as to play the role of filtering and rectifying when the water is discharged normally.

[0078] The two ends of the reset member 3 act on the plate body 21 and the main body 1 respectively. When the needle plate 2 is in the first position, the reset member 3 stores energy. When the water inlet 111 stops water, the needle plate 2 moves to the second position, so that the descaling needle 22 is farther away from the water outlet 141 than in the first position, so that the water flow area of ​​the water outlet 141 becomes larger, and the impurities above the water outlet 141 will be discharged along with the residual water, so that the impurities can be discharged without causing blockage, and there is no need for regular cleaning, which is more convenient.

[0079] In an exemplary embodiment, a filter screen 4 is further included. The filter screen 4 is provided with a plurality of filter holes and is located in the air intake passage 16. By utilizing the thickness of the filter screen 4 itself, the thickness of the air intake passage 16 can be accurately determined during assembly, thereby preventing other substances from entering and causing blockage of the air intake passage 16, and cutting the air during inhalation to form tiny bubbles that are more easily broken.

[0080] In an exemplary embodiment, a tapered section 112 with a gradually decreasing water flow area is provided between the water inlet 111 and the air outlet of the air inlet channel 16 to generate negative pressure when water flows through, thereby achieving air intake in the air inlet channel 16 .

[0081] In an exemplary embodiment, the water outlet 141 includes a guide hole 1411 and a first hole 1412 connected to the guide hole 1411. The guide hole 1411 is closer to the plate body 21 than the first hole 1412. The size of the guide hole 1411 gradually decreases in the direction approaching the first hole 1412. The descaling needle 22 is suitable for inserting into and withdrawing from the first hole 1412 to have a certain guiding effect, thereby preventing the descaling needle 22 from being difficult to insert into the first hole 1412, resulting in impurity removal failure, and reducing manufacturing accuracy and manufacturing cost. In addition, under the action of the guide hole 1411, impurities are also easy to flow out of the water outlet 141 along with the residual water.

[0082] In an exemplary embodiment, a rectifying water channel is provided between the air outlet end of the air inlet channel 16 and the water outlet hole 141, and the rectifying water channel is composed of a plurality of water channels with different water flow directions to achieve the effect of rectifying, and is less likely to accumulate impurities, preventing impurities from failing to reach the water outlet hole 141 and failing to be discharged. Alternatively, the rectifying water channel is provided with a plurality of rectifying holes to achieve the effect of rectifying and prevent the water pattern from being chaotic.

[0083] In an exemplary embodiment, a sealing ring 5 is further included. The sealing ring 5 is installed on the body 1 and is located on the side of the body 1 having the water inlet 111 to achieve a sealing effect when the water outlet is connected to other products to prevent water leakage at the connection point.

[0084] In an exemplary embodiment, the water outlet chamber 15 is also provided with a first limiting surface 143, and the needle plate 2 is provided with a clamping portion 211. The clamping portion 211 or the main body 1 is suitable for deformation so that the clamping portion 211 passes over the first limiting surface 143. The clamping portion 211 is provided with a second limiting surface 2111 opposite to the first limiting surface 143 to prevent the needle plate 2 from separating from the main body 1 under the action of the reset member 3.

[0085] In an exemplary embodiment, the water outlet cavity 15 is further provided with a water outlet through hole 142, which is located around the water outlet hole 141 and communicated with the hole wall of the water outlet hole 141 to increase the water output and assist in discharging impurities under residual water.

[0086] In an exemplary embodiment, a water hole 212 connecting the water inlet 111 and the water outlet 141 is provided on the plate body 21, and / or a water gap 7 connecting the water inlet 111 and the water outlet 141 is provided between the plate body 21 and the wall of the water outlet chamber 15 to achieve water flow. If both are provided, the amount of water flow can be increased. The water hole 212 is also used for impurities to pass through. When the needle plate 2 is in the first position, a water gap 7 connecting the water inlet 111 and the water outlet 141 is provided between the plate body 21 and the wall of the water outlet chamber 15. When it is in the second position, the water gap 7 is closed to prevent debris from clogging the water gap 7, resulting in the inability of the water gap 7 to pass water, or the needle plate 2 is not easily slid by water force.

[0087] In an exemplary embodiment, the air inlet channel 16 has a portion whose air passing size gradually decreases in a direction close to the air outlet end of the air inlet channel 16, so that the size of the bubbles entering the water outlet cavity 15 is smaller and easier to break.

[0088] In an exemplary embodiment, no filter screen is provided at the water inlet 111, which can ensure that impurities directly enter the water outlet and are then discharged through the descaling needle 22 and the water flow without the need for cleaning.

[0089] In an exemplary embodiment, the body 1 includes a shell, and a first air intake component 11 and a second air intake component 12 installed on the shell, the shell is provided with an air inlet 131, the first air intake component 11 is provided with a first surface 113 facing the second air intake component 12 and a first conical surface 114 protruding from the first surface 113, the size of the first conical surface 114 gradually decreases in the direction away from the first surface 113, the second air intake component is provided with a second surface 121 and a second conical surface 122 protruding from the second surface 121, the second surface 121 faces the first surface 113, and the size of the second conical surface 122 gradually decreases in the direction away from the second surface 121; the first surface 113 and the second surface 121 enclose an enlarged section 161 with a gradually increasing air passing size to facilitate a larger air passing amount, the first conical surface 114 and the second conical surface 122 enclose an air passage 162 with a gradually decreasing air passing size, the air inlet 131, the enlarged section 161, and the air passage 162 are connected in sequence to form an air inlet channel. The air passage size of the air passage 162 is gradually reduced to accelerate the air flow and make the bubbles entering the water outlet cavity smaller and easier to break.

[0090] In an exemplary embodiment, the air inlet channel 16 is closer to the water inlet 111 than the needle plate 2 , so that impurities whose adhesion is reduced by the air inlet channel 16 can flow to the needle plate 2 and be discharged with the assistance of the needle plate 2 .
