Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a spray arm structure. Background Technology

[0002] In the existing technology, for rotatable spray arm structures, there is usually a dedicated switch for controlling the water flow of the spray arm. This results in a large number of parts in the spray arm structure. When using the spray arm structure, the user not only needs to rotate the spray arm from the retracted state to the working state, but also needs to operate the switch for controlling the water flow of the spray arm. This makes the operation of the user more complicated and there is room for further improvement. Utility Model Content

[0003] In view of this, this application provides a spray arm structure that allows the user to rotate the spray arm structure from the storage turntable to the working state with only one rotation, and at the same time the water flow of the spray arm is switched from the closed state to the open state, thus making the spray arm structure more convenient and the usage steps of the spray arm structure more convenient.

[0004] In summary, in order to optimize the simplification of the spray arm structure and improve its ease of use, this application proposes a spray arm structure.

[0005] The spray arm structure provided in this application adopts the following technical solution:

[0006] A spray arm structure includes a water distributor and a spray arm. The water distributor has a first water outlet, and the spray arm has a second water inlet. The spray arm is rotatably connected to the water distributor, and the spray arm can achieve the connection or blockage of the first water outlet and the second water inlet by rotation.

[0007] By adopting the above technical solution, the water distributor is fixed in position, and the spray arm can rotate around the water distributor. The difference in the rotation angle of the spray arm around the water distributor allows the spray arm to be divided into a retracted state and a working state. When the spray arm is in the retracted state, the first water outlet and the second water inlet are not connected. When the spray arm is in the working state, the first water outlet and the second water inlet are connected. Thus, when the user needs to clean the spray arm structure, the user only needs to rotate the spray arm structure from the retracted state to the working state to achieve the cleaning work, without having to turn on the switch. For some irregularly shaped spray arms, such as horizontal "L" shaped spray arms or "Y" shaped spray arms, the user can more conveniently adjust the spray arm to the working state with one rotation, improving the ease of use of the spray arm structure. At the same time, the switch structure of the existing technology is omitted, making the overall spray arm structure more streamlined, optimizing the production process of the spray arm structure, and reducing the production cost of the spray arm structure.

[0008] Preferably, the water distributor has a first channel and a rotating cavity. The first channel is connected to the rotating cavity. The first outlet is located at the end of the first channel near the rotating cavity. The spray arm is located inside the rotating cavity, and the second inlet is also located inside the rotating cavity.

[0009] By adopting the above technical solution, when the user rotates the spray arm to the working position, the first water outlet and the second water inlet are connected. Water from the external water source enters the water distributor through the first channel on the water distributor, and then enters the second water inlet through the first water outlet connected to the first channel, thereby allowing water to enter the spray arm. When the user rotates the spray arm to the storage position, the second water inlet and the first water outlet are not connected, and water cannot enter the spray arm from the water distribution pipe. At this time, the spray arm cannot perform cleaning work. At the same time, since both the first water outlet and the second water inlet are located inside the water distributor, the water flow channel between the first water outlet and the second water inlet can be well isolated from the outside, thus having good sealing performance.

[0010] Preferably, the rotation center axis of the spray arm is perpendicular to the axis of the first water outlet; the rotation center axis of the spray arm is perpendicular to the axis of the second water inlet.

[0011] By adopting the above technical solution, the first outlet and the second inlet can be connected or blocked by rotating the spray arm around its own rotation center axis. The structure is simple and convenient, which is conducive to the simplification of the spray arm structure and the production of the spray arm structure.

[0012] Preferably, the water distributor has a rotating cavity, the water distributor includes a first water distribution part and a second water distribution part, the first water distribution part is connected to the second water distribution part, the first water distribution part has a rotating port, the rotating cavity is connected to the rotating port, the spray arm includes a main spray arm, the main spray arm includes an arm body and an arm end, the arm end is located at the rotating cavity and the rotating port, and the arm end is connected to the arm body at the rotating port.

[0013] By adopting the above technical solution, during the production and assembly process of the spray arm structure, the user first passes one end of the arm end through the rotating port and places the other end in the rotating cavity. Then, the first water distribution part and the second water distribution part are connected to form a sealed water channel. Then, the arm body is connected to the arm end located at the rotating port, so that the arm body can rotate with the rotation of the arm end. Thus, the user can achieve the connection or blockage of the second water inlet and the first water outlet by rotating the arm body.

[0014] Preferably, the water distributor has a first groove in the rotating cavity, the first groove being a quarter circle, and a first protrusion is also provided on the end of the arm, the axis of the first protrusion being perpendicular to the rotation center axis of the end of the arm, and the first protrusion being located in the first groove.

[0015] By adopting the above technical solution, the first protrusion restricts the rotation range of the spray arm, so that the spray arm can only rotate around the water distributor within a certain range, which can be 0-90°, just enough to make the spray arm rotate from the storage position to the working position.

[0016] Preferably, it also includes a fixed bracket, which is disposed at the end of the spray arm away from the water distributor, and the fixed bracket is rotatably connected to the spray arm.

[0017] By adopting the above technical solution, the spray arm is located between the water distributor and the fixed bracket, making the position of the spray arm relatively stable and preventing it from shaking. This makes it more convenient for users to rotate the spray arm without having to consider the shaking of the spray arm in other directions, or the force exerted by the user on the rotation of the spray arm being converted into force in other directions to affect the rotation effect of the spray arm.

[0018] Preferably, it also includes a basket, the water distributor is connected to the basket, the fixed bracket is connected to the basket, one end of the spray arm is rotatably connected to the water distributor, and the other end is rotatably connected to the fixed bracket.

[0019] By adopting the above technical solution, the basket facilitates the storage of the water dispenser, spray arm, and fixed bracket, effectively utilizing kitchen space.

[0020] Preferably, the spray arm includes a main spray arm and an auxiliary spray arm. The main spray arm is rotatably connected to the water distributor, and the auxiliary spray arm is connected to the main spray arm. The upper part of the vertical cross-section of the main spray arm is half a circle, and the lower part is rectangular. The auxiliary spray arm includes an upper part and a lower part. The upper part and the lower part of the auxiliary spray arm are connected. The outer diameter of the lower part of the auxiliary spray arm is larger than that of the upper part of the auxiliary spray arm. A cleaning hole is provided on the upper part of the auxiliary spray arm.

[0021] By adopting the above technical solution, external water flows into the second inlet of the main spray arm through the first outlet of the water distributor, then into the auxiliary spray arm, and finally sprays out from the cleaning hole of the auxiliary spray arm. The shape of the main spray arm allows the lower, left, and right sides of the main spray arm to fit against the installation surface of the water distributor, so that the main spray arm can stably fit against the installation surface of the water distributor whether it is rotated to the storage state or the working state, thus ensuring the stability of the storage state or the working state. The larger outer diameter of the lower part of the auxiliary spray arm makes it easier for the auxiliary spray arm to stand up stably, and the upper part of the lower part of the auxiliary spray arm is convenient for the deep cup to be placed upside down, so that the upper part of the upper part of the auxiliary spray arm can rinse the inner end of the deep cup.

[0022] Preferably, the first water outlet is arc-shaped, and the second water inlet is also arc-shaped.

[0023] By adopting the above technical solution, when the spray arm is in the retracted position, the first water outlet and the second water inlet are not connected, and the spray arm cannot perform water spraying cleaning work at this time. When the user gradually rotates from the retracted position to the working position, the arc-shaped second water inlet and the arc-shaped first water outlet gradually overlap, and the water flow from the auxiliary spray arm gradually increases. When the arc-shaped second water inlet and the arc-shaped first water outlet completely overlap, the water flow is at its maximum.

[0024] Preferably, the first water outlet is teardrop-shaped, and the second water inlet is also teardrop-shaped.

[0025] By adopting the above technical solution, when the spray arm is in the retracted position, the first water outlet and the second water inlet are not connected, and the spray arm cannot perform water spraying cleaning work at this time. When the user gradually rotates from the retracted position to the working position, the teardrop-shaped second water inlet and the teardrop-shaped first water outlet gradually overlap, and the water flow from the spray arm has a significant difference in flow rate. When the teardrop-shaped second water inlet and the teardrop-shaped first water outlet completely overlap, the water flow is at its maximum.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The water distributor is fixed in position, and the spray arm can rotate around the water distributor. By varying the rotation angle of the spray arm around the water distributor, the spray arm can be divided into a retracted state and a working state. When the spray arm is in the retracted state, the first water outlet and the second water inlet are not connected. When the spray arm is in the working state, the first water outlet and the second water inlet are connected. This allows users to easily clean the spray arm by simply rotating it from the retracted state to the working state, without needing to turn on a switch. This makes it easier for users to adjust the spray arm to a working state with a single rotation, such as horizontal "L" shaped spray arms or "Y" shaped spray arms, improving the ease of use of the spray arm structure. It also eliminates the need for the existing switch structure, making the overall spray arm structure more streamlined, optimizing the production process, and reducing the production cost of the spray arm structure.

[0028] 2. During the production and assembly of the spray arm structure, the user first passes one end of the arm through the rotating port and places the other end in the rotating cavity. Then, the first water distribution part and the second water distribution part are connected to form a sealed water channel. Then, the arm body is connected to the arm end located at the rotating port, so that the arm body can rotate with the rotation of the arm end. Thus, the user can achieve the connection or blockage of the second water inlet and the first water outlet by rotating the arm body.

[0029] 3. External water flows into the second inlet of the main spray arm through the first outlet of the water distributor, then into the auxiliary spray arm, and finally sprays out from the cleaning hole of the auxiliary spray arm. The shape of the main spray arm allows the lower, left, and right sides of the main spray arm to fit against the installation surface of the water distributor. This ensures that the main spray arm can stably fit against the installation surface of the water distributor whether it is rotated to the storage state or the working state, thus guaranteeing the stability of the storage state or the working state. The larger outer diameter of the lower part of the auxiliary spray arm makes it easier for the auxiliary spray arm to stand up stably. On the other hand, the upper part of the lower part of the auxiliary spray arm is convenient for the deep cup to be placed upside down, so that the upper part of the upper part of the auxiliary spray arm can rinse the inner end of the deep cup.

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a spray arm structure.

[0037] Reference Figures 1-4 It includes a water distributor 1 and a spray arm 2. The spray arm 2 includes a main spray arm 3 and a secondary spray arm 4. One end of the main spray arm 3 is rotatably connected to the water distributor 1. The secondary spray arm 4 is integrally formed with the main spray arm 3, so that the axis of the secondary spray arm 4 is perpendicular to the axis of the main spray arm 3.

[0038] The water distributor 1 has a first channel 7, with a first inlet 25 at the end of the first channel 7 away from the main spray arm 3 and a first outlet 5 at the end of the first channel 7 near the main spray arm 3. The axis of the first outlet 5 is perpendicular to the rotation center axis of the main spray arm 3. The main spray arm 3 also has a second channel, with a second inlet 6 on the outer wall of the main spray arm 3 near the first outlet 5. The second inlet 6 is connected to the second channel, and the center axis of the second inlet 6 is perpendicular to the center axis of the second channel, so that when the main spray arm 3 rotates at a certain angle, the second inlet 6 on the main spray arm 3 is connected to the first outlet 5 on the water distributor 1. The auxiliary spray arm 4 has a third channel, which is also connected to the second channel. The auxiliary spray arm 4 also has a cleaning hole 22 for cleaning deep cups.

[0039] During use, the water distributor 1 is in a fixed position, and the spray arm 2 can rotate around the water distributor 1. When the user rotates the auxiliary spray arm 4, the main spray arm 3 rotates on the water distributor 1 accordingly. When the auxiliary spray arm 4 on the spray arm 2 is in contact with the mounting surface of the water distributor 1, the first water outlet 5 and the second water inlet 6 are separated, the water channel is blocked, and the spray arm 2 is in the retracted position. When the auxiliary spray arm 4 rotates 0-17° from the mounting surface of the water distributor 1, the water channel is still not connected, and the spray arm 2 is in the non-working position. The auxiliary spray arm 4 continues to rotate away from the mounting surface of the water distributor 1. In particular, when the angle between the auxiliary spray arm 4 and the mounting surface of the water distributor 1 is 17°-90°, the first water outlet 5 and the second water inlet 6 are connected, the water channel is connected, and the spray arm 2 is in the working state of spraying water. In practical use, the user first rotates the auxiliary spray arm 4 0-17° from its position against the mounting surface of the water dispenser 1. Then, the deep-mouthed cup to be cleaned is placed on the auxiliary spray arm 4, and the spray arm 2 is rotated further until the angle between the spray arm 2 and the mounting surface of the water dispenser 1 is between 17° and 90°, opening the water channel. The spray arm 2 then sprays water to clean the cup. Especially when the auxiliary spray arm 4 is vertically upward, the balance between the deep-mouthed cup and the spray arm 2 is optimal, ensuring the cup remains stable and does not wobble during the cleaning process. After cleaning, the user slightly rotates the auxiliary spray arm 4 to the non-working state, removes the cup, and then rotates the auxiliary spray arm 4 back to its position against the mounting surface of the water dispenser 1. In summary, the process of cleaning deep-mouthed cups is convenient, requiring no special operation. The steps of using the spray arm structure are simple, and the rotatable spray arm 2 allows it to be stored against the mounting surface of the water dispenser 1, resulting in a smaller overall height and making it suitable for use in storage spaces such as cupboards.

[0040] Furthermore, in this embodiment, the water distributor 1 includes a first water distribution section 19 and a second water distribution section 20. The first water distribution section 19 has a water distribution trough 21 for forming the first channel 7 and a rotating cavity 8. The first water outlet 5 is located at one end of the water distribution trough 21 near the rotating cavity 8. The first water distribution section 19 also has a rotating opening at the rotating cavity 8. The second water distribution section 20 also has a water distribution trough 21 for forming the first channel 7 and a rotating cavity 8. The first water distribution section 19 and the second water distribution section 20 are bolted together.

[0041] The main spray arm 3 includes an arm body 23 and an arm end 24. The arm body 23 and the arm end 24 are sealed and inserted together. The arm end 24 is located in the rotating cavity 8 of the water distributor 1. The second water inlet 6 is opened on the outer wall of the arm end 24. The end of the arm end 24 used to connect to the arm body 23 is located at the rotating cavity, so that the arm end 24 and the arm body 23 are inserted at the rotating cavity. The arm end 24 can rotate in the rotating cavity 8. The auxiliary spray arm 4 is integrally formed on the outer wall of the arm body 23.

[0042] During the assembly of the spray arm structure, the operator first places the arm end 24 at the rotating cavity 8 of the first water distribution section 19, then inserts the arm end 24 and the arm body 23 into the rotating port of the first water distribution section 19, and finally bolts the first water distribution section 19 and the second water distribution section 20 together. During use, when the user rotates the spray arm 2 to the working position, the first water outlet 5 connects with the second water inlet 6. Water from an external source enters the water distributor 1 through the first channel 7 on the water distributor 1, and flows through the first channel 7. Water enters the second inlet 6 at the end of the arm 24 through the outlet 5, thus allowing water to enter the second channel of the spray arm 2. When the user rotates the spray arm 2 to the storage position or the non-working position, the second inlet 6 is not connected to the first inlet 25, and water cannot enter the spray arm 2 from the water distribution pipe. At this time, the spray arm 2 cannot clean the deep cup. Meanwhile, since the first outlet 5 and the second inlet 6 are both located inside the water distributor 1, the water flow channel between the first outlet 5 and the second inlet 6 can be well isolated from the outside, thus having good sealing performance.

[0043] Furthermore, in this embodiment, the arm end 24 has a first protrusion 10 integrally formed radially at the end away from the arm body 23, that is, the axis of the first protrusion 10 is perpendicular to the rotation center axis of the main spray arm 3. The first water distribution part 19 has a first groove 9 at the position relative to the first protrusion 10. The first groove 9 is quarter-circle in shape. The first protrusion 10 is located in the first groove 9. The rotation range of the spray arm 2 is restricted by the first protrusion 10, so that the spray arm 2 can only rotate around the water distributor from 0-90°, so that the spray arm 2 can rotate around the water distributor 1 by 90°, just so that the auxiliary spray arm 4 rotates from the position of being in contact with the mounting surface of the water distributor 1 to the position of the auxiliary spray arm 4 being perpendicular to the mounting surface of the water distributor 1.

[0044] Furthermore, in this embodiment, the arm end 24 has a third protrusion 16 integrally formed at the end away from the arm body 23. Part of the third protrusion 16 is an arc that mates with the rotating cavity 8, and the other part is a protrusion. The third protrusion 16 can ensure the tightness of the fit between the arm end 24 and the rotating cavity 8, and will not affect the rotation of the arm end 24 in the rotating cavity 8.

[0045] Furthermore, in this embodiment, the arm end 24 is fitted with two sealing rings 11 inside the rotating cavity 8, and the second water inlet 6 on the arm end 24 is located between the two sealing rings 11. The first water outlet 5 on the inner wall of the rotating cavity 8 is also located between the two sealing rings 11, so that the first water outlet 5 and the second water inlet 6 are isolated from other parts of the rotating cavity 8, so that the water flow path is through the first channel 7, the rotating cavity 8 part between the two sealing rings 11, and the second channel, reducing water leakage and affecting use.

[0046] Furthermore, in this embodiment, the auxiliary spray arm 4 includes an upper part 17 and a lower part 18. The upper part 17 and the lower part 18 are integrally formed. The outer diameter of the lower part 18 is larger than that of the upper part 17. The cleaning hole 22 is opened on the upper part 17. The larger outer diameter of the lower part 18 makes it easier for the auxiliary spray arm 4 to stand up stably. On the other hand, the upper side of the lower part 18 is convenient for the deep cup to be placed upside down, so that the upper end of the upper part 17 can rinse the inner end of the deep cup.

[0047] Furthermore, in this embodiment, the vertical cross-sectional shape of the main spray arm 3 is partly a half-circle and partly a rectangle. (When the main spray arm 3 is rotated to the retracted state, the right part of the vertical cross-sectional shape of the main spray arm 3 is a half-circle and the left part is a rectangle.) When the main spray arm 3 is rotated to the working state, the upper part of the vertical cross-sectional shape of the main spray arm 3 is a half-circle and the lower part is a rectangle, so that the lower, left and right sides of the main spray arm 3 can fit against the mounting surface of the water distributor 1. Thus, the main spray arm 3 can stably fit against the mounting surface of the water distributor 1 whether it is rotated to the retracted state or the working state, thereby ensuring the stability of the retracted state or the working state.

[0048] Furthermore, in this embodiment, the first outlet 5 is arc-shaped, and the second inlet 6 is also arc-shaped. When the auxiliary spray arm 4 is in contact with the mounting surface of the water distributor 1, the second inlet 6 and the first outlet 5 are not completely overlapping. At this time, the water distributor 1 and the spray arm 2 are not connected. When the auxiliary spray arm 4 gradually rotates 0-17° away from the mounting surface of the water distributor 1, the spray arm 2 is in a non-working position. When the auxiliary spray arm 4 continues to rotate away from the mounting surface of the water distributor 1, the angle between the auxiliary spray arm 4 and the mounting surface of the water distributor 1 gradually increases from 17° to 90°. At this time, the arc-shaped second inlet 6 and the arc-shaped first outlet 5 gradually overlap, and the water flow from the auxiliary spray arm 4 gradually increases. When the arc-shaped second inlet 6 and the arc-shaped first outlet 5 completely overlap, the water flow is at its maximum, and the auxiliary spray arm 4 has just rotated 90°.

[0049] Furthermore, in this embodiment, a fixed bracket 12 is also included. The fixed bracket 12 is rotatably connected to the end of the main spray arm 3 away from the water distributor 1. The spray arm 2 is located between the water distributor 1 and the fixed bracket 12, making the position of the spray arm 2 relatively stable and preventing it from shaking. This makes it more convenient for the user to rotate the auxiliary spray arm 4 without having to consider the shaking of the spray arm 2 in other directions, or the force exerted by the user on the rotation of the spray arm 2 being converted into a force in other directions that affects the rotation effect of the spray arm 2.

[0050] Furthermore, in this embodiment, the fixed bracket 12 has a second protrusion 13 integrally formed at the end away from the main spray arm 3. The second protrusion 13 has a second groove 14, and the second protrusion 13 has a slope 15 near the second groove 14. The second protrusions 13 are mirror images of each other on the fixed bracket 12, so that the user can use the second groove 14 on the second protrusion 13 to lock the fixed bracket 12 into the storage structure with a strip structure, such as a basket or bracket. The slope 15 facilitates the removal of the fixed bracket 12 from the strip structure.

[0051] Furthermore, in this embodiment, a basket is also included. The water dispenser 1 is connected to the basket, and the fixing bracket 12 is engaged with the basket through the second protrusion 13 to fix the water dispenser 1 on the basket. The fixing bracket 12 is also located on the basket. The spray arm 2 is rotatably connected to the water dispenser 1 and the fixing bracket 12. By storing the water dispenser 1 and the spray arm 2 on the basket, it is convenient to clean and store the deep cup, and the overall space is used efficiently.

[0052] Furthermore, in this embodiment, when the user installs the spray arm structure on the basket, the water distributor 1 is positioned front and back inside the basket, and the water distributor 1 is attached to the left end of the basket, thereby reducing the division of the basket's internal space by the water distributor 1, which has a certain volume. At the same time, the spray arm 2 is located to the right of the water distributor 1, and the fixing bracket 12 is located to the right of the spray arm 2, so that when the spray arm 2 is in the storage position, the upper part 17 of the auxiliary spray arm is located in front of the basket, and the lower part 18 of the auxiliary spray arm is located in the rear of the basket, making it convenient for the user to stand in front of the basket and rotate the auxiliary spray arm 4.

[0053] Furthermore, in this embodiment, the left and right ends of the basket are bent inward to form a recess, and the front end of the water distributor 1 is also bent inward, so that the front end of the water distributor 1 is shaped like a "7". The first water inlet 25 of the water distributor 1 is located at the recessed position of the basket, and the shape of the water distributor 1 fits the left end of the basket, so that the recessed position of the basket can accommodate a pipe for connecting to the first water inlet 25.

[0054] Furthermore, in this embodiment, the horizontal height of the front end of the fixed bracket 12 is less than the horizontal height of the rear end of the fixed bracket 12. The rear end of the fixed bracket 12 is used to rotate and cooperate with the right end of the main spray arm 3. The lower end of the fixed bracket 12 is provided with a bracket groove for cooperating with the basket. The second protrusion 13 is located at the left end of the fixed bracket 12. The bracket groove of the fixed bracket 12 allows the fixed bracket 12 to be partially set outside the lower side of the basket. At the same time, the left end of the fixed bracket 12 cooperates with the basket, so that the fixed bracket 12 has a small volume while satisfying the requirement of stably limiting the spray arm 2. This allows the entire water distributor 1, spray arm 2 and fixed bracket 12 to occupy a small volume inside the basket. Moreover, the fixed bracket 12 will not divide the volume inside the basket, causing unnecessary occupation of additional volume inside the basket due to space division. This allows the volume inside the basket to be used more efficiently.

[0055] Furthermore, in this embodiment, the main spray arm 3 has an integrally formed protrusion at the position between the secondary spray arm 4 and the secondary spray arm 4, which strengthens the main spray arm 3.

[0056] Furthermore, in this embodiment, the lower side of the first water distribution part 19 is integrally formed with a first hook for hooking with the basket, and the first hook is bent forward. The left end of the second water distribution part 20 is integrally formed with a second hook, and the second hook is bent forward. The left end of the second water distributor 1 is integrally formed with a third hook, and the third hook is bent backward. The bending position of the third hook is on the same vertical line as the bending position of the second hook. Thus, when the user rotates the auxiliary spray arm 4, the first hook can prevent the water distributor 1 from moving backward. The second hook and the third hook cooperate to connect with the basket, thereby preventing the water distributor 1 from moving back and forth.

[0057] Furthermore, in this embodiment, the present invention does not impose any particular limitation on the angle between the axis of the auxiliary spray arm 4 and the axis of the main spray arm 3. Any method known to those skilled in the art can be used to ensure that the auxiliary spray arm 4 can stably hold the deep cup when the main spray arm 3 is rotated to a non-working position or working position, and that the auxiliary spray arm 4 can fit against the mounting surface of the water distributor 1 when the main spray arm 3 is rotated to a retracted state. Those skilled in the art can select and adjust according to specific application conditions and product requirements.

[0058] Furthermore, in this embodiment, the present invention does not particularly limit the non-working position range and working position range of the spray arm 2. It can be implemented in a way that is well known to those skilled in the art, which allows the spray arm 2 to fit the cup in the non-working range, and the spray arm 2 with the cup fitted in the working range to be stable in shape and operation. Those skilled in the art can select and adjust according to specific application conditions and product requirements. Preferably, the non-working range is the auxiliary spray arm rotating 0-17° from the water distributor mounting surface; preferably, the working range is the auxiliary spray arm rotating 17°-90° from the water distributor mounting surface.

[0059] Furthermore, in this embodiment, the present invention does not impose any particular limitation on the specific shape of the first channel 7, the second channel, and the third channel. Any shape known to those skilled in the art that enables water to flow from the water distributor 1 to the cleaning hole 22 can be used. Those skilled in the art can select and adjust the shape according to the specific application and product requirements.

[0060] Furthermore, in this embodiment, the present invention does not particularly limit the specific shape of the first outlet 5 and the second inlet 6. Any shape known to those skilled in the art that enables water to flow from the first outlet 5 to the second inlet 6 can be used. Those skilled in the art can select and adjust the shape according to the specific application and product requirements. The shape is preferably circular, more preferably arc-shaped, and more preferably teardrop-shaped.

[0061] Furthermore, in this embodiment, the present invention does not impose any particular limitation on the specific shape or structure of the spray arm 2. It can be any shape or structure of the spray arm 2 with a storage state and a working state that is well known to those skilled in the art.
