Description

Technical Field

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

[0002] In the prior art, there are usually two ways for the spray arm structure to clean deep-mouth glass cups. One is to fix the spray arm structure on the tabletop and wash the deep-mouth cups by placing them on the spray arm structure. This cleaning method has a relatively fixed floor area and is not convenient for storage. The other way is to clean the deep-mouth cups through a rotatable spray arm structure. Since the spray arm structure can be rotated for storage, it saves space, but the user still needs to operate the switch to start the water flow, so there is room for further improvement. Summary of the Invention

[0003] In view of this, this application provides a spray arm structure for cleaning glass cups. When the user needs to clean a deep-mouth cup, the user can sleeve the deep-mouth cup on the secondary spray arm and then rotate the secondary spray arm to achieve the flushing of the deep-mouth cup without deliberately turning on the switch. This not only makes the spray arm structure storable but also makes the steps for the user to use the spray arm structure relatively simple.

[0004] In summary, in order to optimize the convenience of the spray arm structure for cleaning glass cups, this application proposes a spray arm structure for cleaning glass cups.

[0005] The spray arm structure for cleaning glass cups provided by this application adopts the following technical solutions:

[0006] A spray arm structure for cleaning glass cups includes a water distributor and a spray arm. The spray arm includes a main spray arm and a secondary spray arm. The main spray arm is rotatably connected to the water distributor. The secondary spray arm is connected to the main spray arm and is in communication with the main spray arm. The water distributor is provided with a first water outlet near the main spray arm. The axis of the rotation center of the main spray arm is perpendicularly arranged to the axis of the first water outlet. The main spray arm is provided with a second water inlet. The axis of the second water inlet is perpendicularly arranged to the axis of the rotation center of the main spray arm, so that the rotation of the main spray arm realizes the connection or disconnection between the first water outlet and the second water inlet.

[0007] By adopting the above technical solution, the position of the water distributor is fixed, and the spray arm can rotate around the water distributor. When the user rotates the secondary spray arm, the main spray arm rotates on the water distributor accordingly. When the secondary spray arm on the spray arm fits the installation surface of the water distributor, the first water outlet and the second water inlet are cut off, and at this time the water channel is blocked, and the spray arm is in the storage position. When the secondary spray arm rotates 0 - 17° from the installation surface of the water distributor, the water channel is still not connected at this time, and the spray arm is in the non-working position; the secondary spray arm continues to rotate away from the installation surface of the water distributor. In particular, when the angle between the secondary spray arm and the installation surface of the water distributor is 17° - 90°, the first water outlet and the second water inlet are connected, and the water channel is connected. At this time, the spray arm is in the working state of spraying water. In actual use, the user first rotates the secondary spray arm 0 - 17° from the position where it fits the installation surface of the water distributor, then sleeks the deep-mouth cup to be cleaned on the secondary spray arm, and continues to rotate the spray arm so that the angle between the spray arm and the installation surface of the water distributor ranges from 17° to 90°. The water channel is opened, and then the spray arm sprays water to clean the cup. Especially when the secondary spray arm is vertically upward, at this time, the balance between the deep-mouth cup and the spray arm is the best, making the deep-mouth cup more stable during the cleaning process and not shaking. After the cleaning is completed, the user slightly rotates the secondary spray arm to the non-working state, then removes the cup, and finally continues to rotate the secondary spray arm until it fits the installation surface of the water distributor. In summary, the process of the user cleaning the deep-mouth cup is relatively convenient, without the need to deliberately turn on the switch. The steps of using the spray arm structure are relatively simple, and the rotatable spray arm enables the spray arm to be stored by fitting the installation surface of the water distributor, making the entire spray arm structure occupy a relatively small space height, and thus facilitating the spray arm structure to be adapted to storage spaces such as cupboards.

[0008] Preferably, a first channel is opened in the water distributor, a rotation cavity is also opened in the water distributor, the first channel is communicated with the rotation cavity, the first water outlet is located at one end of the first channel close to the rotation cavity, one end of the main spray arm is rotatably connected with the rotation cavity, a second channel is opened in the main spray arm, the second water inlet is communicated with the second channel, and the second water inlet is located in the rotation cavity.

[0009] By adopting the above technical solution, when the user rotates the secondary spray arm to the working position, the first water outlet and the second water inlet are connected, and the water from the external water source enters the water distributor through the first channel on the water distributor, and enters the second water inlet through the first water outlet communicated with the first channel, thereby realizing the water entering the second channel in the spray arm; when the user rotates the spray arm to the storage position or the non-working position, the second water inlet and the first water inlet are not connected, and the water cannot enter the spray arm from the water distribution pipe. At this time, the spray arm cannot clean the deep-mouth cup. At the same time, since both the first water outlet and the second water inlet are located in the water distributor, the water flow channel between the first water outlet and the second water inlet can better isolate the outside world and has good sealing performance.

[0010] Preferably, the water distributor is provided with a first groove on the rotating cavity. The first groove is a quarter circle. The main spray arm is further provided with a first protrusion. The axis of the first protrusion is perpendicular to the rotation center axis of the main spray arm. The first protrusion is located in the first groove.

[0011] By adopting the above technical solution, the rotation range of the spray arm is limited by the first protrusion, so that the spray arm can only rotate around the water distributor within a certain range. The rotation range can be 0-90°, just making the secondary spray arm rotate from the position where it fits the installation surface of the water distributor to the position where the secondary spray arm is perpendicular to the installation surface of the water distributor.

[0012] Preferably, 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 main spray arm includes an arm body part and an arm end part. The arm end part is sealed and rotatably connected to the first water distributor. At least part of the arm end part is located outside the water distributor. The end of the arm end part located outside the water distributor is connected to the arm body part.

[0013] By adopting the above technical solution, during the production and assembly process of the spray arm structure, the user first rotatably connects the arm end part to the first water distribution part, so that the arm end part can rotate within the water distributor. Then the first water distribution part and the second water distribution part are connected to form a sealed water channel. Then, through the connection between the arm end part located outside the water distribution part and the arm body part, the water flow enters the arm end part from the first water distribution part and the second water distribution part, and then enters the arm body part from the arm end part.

[0014] Preferably, rotating cavities are provided on both the first water distribution part and the second water distribution part. The first water outlet is located on the side wall of the rotating cavity. The first water distribution part is further provided with a rotating opening. Part of the arm end part is located in the rotating cavity, and the other part is located at the rotating opening.

[0015] 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 part through the rotating opening, and places the other end in the rotating cavity of the first water distribution part. Secondly, the first water distribution part and the second water distribution part are connected to form a sealed water channel. Then the arm body part is connected to the arm end part located at the rotating opening, so that the secondary spray arm on the arm body part can rotate with the rotation of the arm end part. Thus, the user can realize the conduction or blockage of the second water inlet and the first water outlet by rotating the secondary spray arm.

[0016] Preferably, it further includes a fixing bracket. The fixing bracket is arranged at one end of the main spray arm far from the water distributor. The fixing bracket is rotatably connected to the main 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 without shaking. As a result, it is more convenient for the user to rotate the secondary spray arm without having to consider the shaking of the spray arm in other directions, nor having to consider the conversion of the force applied by the user to rotate the spray arm into a force in other directions that may affect the rotation effect of the spray arm.

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

[0019] By adopting the above technical solution, the water distributor, the spray arm and the fixed bracket are arranged on the basket. When the user does not need the spray arm to clean cups or bowls, the user rotates the secondary spray arm to the storage position. At this time, the secondary spray arm is arranged in contact with the bottom of the basket. When the user needs the spray arm to clean a deep-mouth cup, the user rotates the secondary spray arm to the non-working position, and the secondary spray arm is arranged at an angle with the bottom of the basket. Then the user sleeved the deep-mouth cup to be cleaned on the secondary spray arm, and then continues to rotate the secondary spray arm to the working position. The secondary spray arm sprays water to clean the deep-mouth cup. After the cleaning is completed, the user rotates the secondary spray arm to the non-working position, removes the deep-mouth cup, and continues to rotate the spray arm to the storage position in contact with the bottom of the basket. By storing the water distributor and the spray arm on the basket, it is not only convenient for the cleaning and storage of the deep-mouth cup, but also can store the secondary spray arm used for cleaning the deep-mouth cup, reducing the space occupied by the secondary spray arm in the kitchen, and thus making efficient use of the overall kitchen space.

[0020] Preferably, the fixed bracket is provided with a second protrusion. A second groove is opened on the second protrusion. The second protrusion is provided with an inclined surface near the second groove.

[0021] By adopting the above technical solution, the user can fix the fixed bracket in a storage structure with a strip structure, such as a basket, a bracket, etc., through the second groove on the second protrusion, and the inclined surface facilitates the removal of the fixed bracket from the strip structure.

[0022] Preferably, the secondary spray arm includes an upper part of the secondary spray arm and a lower part of the secondary spray arm. The upper part of the secondary spray arm is connected to the lower part of the secondary spray arm. The outer diameter of the lower part of the secondary spray arm is larger than that of the upper part of the secondary spray arm. Cleaning holes are opened on the upper part of the secondary spray arm.

[0023] By adopting the above technical solution, the larger outer diameter of the lower part of the secondary spray arm is convenient for the secondary spray arm to stand stably on one hand, and on the other hand, the upper side of the lower part of the secondary spray arm is convenient for the deep-mouth cup to be placed upside down, so that the upper end of the upper part of the secondary spray arm can wash the inner end of the deep-mouth cup.

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

[0025] By adopting the above technical solution, when the secondary spray arm is attached to the installation surface of the water distributor, the second water inlet and the first water outlet do not coincide at all. At this time, the water distributor and the spray arm are not connected. When the secondary spray arm gradually rotates 0 - 17° away from the installation surface of the water distributor, the spray arm is in a non-working position. When the secondary spray arm continues to rotate away from the installation surface of the water distributor and the angle formed between the secondary spray arm and the installation surface of the water distributor gradually changes from 17° to 90°, the arc-shaped second water inlet and the arc-shaped first water outlet gradually coincide, and the water flow sprayed by the secondary spray arm gradually increases. When the arc-shaped second water inlet and the arc-shaped first water outlet completely coincide, the water flow is the largest at this time, and the secondary spray arm just rotates 90°.

[0026] Preferably, the upper part of the vertical cross-section of the main spray arm is a semi-circle, and the lower part is a rectangle.

[0027] By adopting the above technical solution, the lower side, left side, and right side of the main spray arm can all be attached to the installation surface of the water distributor, so that the main spray arm can be stably attached to the installation surface of the water distributor whether it rotates to the storage state or the working state, thus ensuring the stability of the storage state or the working state.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The position of the water distributor is fixed, and the spray arm can rotate around the water distributor. When the user rotates the secondary spray arm, the main spray arm rotates on the water distributor accordingly. When the secondary spray arm on the spray arm fits the installation surface of the water distributor, the first water outlet and the second water inlet are cut off, and the water channel is not connected at this time, and the spray arm is in the storage position. When the secondary spray arm rotates 0-17° from the installation surface of the water distributor, the water channel is still not connected at this time, and the spray arm is in the non-working position; the secondary spray arm continues to rotate away from the installation surface of the water distributor. In particular, when the angle between the secondary spray arm and the installation surface of the water distributor is 17°-90°, the first water outlet and the second water inlet are connected, and the water channel is connected. At this time, the spray arm is in the working state of spraying water. In actual use, the user first rotates the secondary spray arm 0-17° from the position where it fits the installation surface of the water distributor, then sleeved the deep-mouth cup to be cleaned on the secondary spray arm, and continues to rotate the spray arm so that the angle between the spray arm and the installation surface of the water distributor is in the range of 17°-90°. The water channel is opened, and then the spray arm sprays water to clean the cup. In particular, when the secondary spray arm is vertically upward, at this time, the balance between the deep-mouth cup and the spray arm is the best, so that the deep-mouth cup is relatively stable during the cleaning process and will not shake. After the cleaning is completed, the user slightly rotates the secondary spray arm to the non-working state, then removes the cup, and finally continues to rotate the secondary spray arm until it fits the installation surface of the water distributor. In summary, the process of the user cleaning the deep-mouth cup is relatively convenient, without deliberately turning on the switch. The steps of using the spray arm structure are relatively simple, and the rotatable spray arm enables the spray arm to be stored by fitting the installation surface of the water distributor, making the overall space height occupied by the spray arm structure smaller, and thus facilitating the spray arm structure to be adapted to storage spaces such as cupboards;

[0030] 2. During the production and assembly process of the spray arm structure, the user first passes one end of the arm end through the rotation port, and places the other end in the rotation cavity of the first water distribution part. Secondly, the first water distribution part and the second water distribution part are connected to form a sealed water channel. Then, the arm body part is connected to the arm end at the rotation port, so that the secondary spray arm on the arm body part can rotate with the rotation of the arm end, thereby enabling the user to realize the conduction or blocking of the second water inlet and the first water outlet by rotating the secondary spray arm;

[0031] 3. Set the water distributor, spray arm and fixed bracket on the basket. When the user does not need the spray arm to clean cups or bowls, the user turns the secondary spray arm to the storage position. At this time, the secondary spray arm is arranged to fit the bottom of the basket. When the user needs the spray arm to clean deep-mouthed cups, the user rotates the secondary spray arm to the non-working position. The secondary spray arm is arranged at an angle with the bottom of the basket. Then the user sleeved the deep-mouthed cup to be cleaned on the secondary spray arm, and then continues to rotate the secondary spray arm to the working position. The secondary spray arm sprays water to clean the deep-mouthed cup. After the cleaning is completed, the user rotates the secondary spray arm to the non-working position, removes the deep-mouthed cup, and continues to rotate the spray arm to the storage position where it fits the bottom of the basket. By storing the water distributor and the spray arm on the basket, it is not only convenient for the cleaning and storage of deep-mouthed cups, but also can store the secondary spray arm used for cleaning deep-mouthed cups, reducing the occupancy of the secondary spray arm in the kitchen space, and thus making efficient use of the overall kitchen space;

[0032] 4. Both the first water outlet and the second water inlet are arc-shaped. When the secondary spray arm fits the installation surface of the water distributor, the second water inlet and the first water outlet do not coincide at all. At this time, the water distributor and the spray arm are not connected. When the secondary spray arm gradually rotates 0 - 17° away from the installation surface of the water distributor, the spray arm is in the non-working position at this time. When the secondary spray arm continues to rotate away from the installation surface of the water distributor, and the angle formed by the secondary spray arm and the installation surface of the water distributor gradually changes from 17° to 90°, the arc-shaped second water inlet and the arc-shaped first water outlet gradually coincide, and the water flow sprayed by the secondary spray arm gradually increases. When the arc-shaped second water inlet and the arc-shaped first water outlet completely coincide, the water flow is the largest at this time, and the secondary spray arm just rotates 90°.

Detailed implementation mode

[0038] The following will further elaborate on this application in conjunction with the attached Figures 1-4 drawings for a more detailed description.

[0039] The embodiment of this application discloses a spray arm structure for cleaning glass cups.

[0040] Referring to 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, and the secondary spray arm 4 is integrally formed with the main spray arm 3, such that the axis of the secondary spray arm 4 is perpendicular to the axis of the main spray arm 3.

[0041] A first channel 7 is provided in the water distributor 1. The end of the first channel 7 far from the main spray arm 3 is a first water inlet 25, and a first water outlet 5 is provided at the end of the first channel 7 close to the main spray arm 3. The axis of the first water outlet 5 is perpendicular to the rotation center axis of the main spray arm 3; a second channel is also provided in the main spray arm 3. A second water inlet 6 is provided on the outer wall of the main spray arm 3 close to the first water outlet 5. The second water inlet 6 is communicated with the second channel, and the central axis of the second water inlet 6 is perpendicular to the central axis of the second channel, such that when the main spray arm 3 rotates by a certain angle, the second water inlet 6 on the main spray arm 3 is communicated with the first water outlet 5 on the water distributor 1; a third channel is provided in the secondary spray arm 4, and the third channel is also communicated with the second channel. The secondary spray arm 4 is also provided with cleaning holes 22 for cleaning deep-mouth cups.

[0042] During use, the water distributor 1 is fixed in position, and the spray arm 2 can rotate around the water distributor 1. When the user rotates the secondary spray arm 4, the main spray arm 3 rotates on the water distributor 1 accordingly. When the secondary spray arm 4 on the spray arm 2 fits against the mounting surface of the water distributor 1, the first water outlet 5 is blocked from the second water inlet 6, and at this time the water channel is blocked, and the spray arm 2 is in the retracted position. When the secondary spray arm 4 rotates 0 - 17° from the mounting surface of the water distributor 1, the water channel is still not connected at this time, and the spray arm 2 is in the non - working position; the secondary spray arm 4 continues to rotate away from the mounting surface of the water distributor 1. In particular, when the angle between the secondary spray arm 4 and the mounting surface of the water distributor 1 is 17° - 90°, the first water outlet 5 is connected to the second water inlet 6, and the water channel is connected. At this time, the spray arm 2 is in the working state of spraying water. In actual use, the user first rotates the secondary spray arm 4 0 - 17° from the position where it fits against the mounting surface of the water distributor 1, then sleeks the deep - mouth cup to be cleaned onto the secondary spray arm 4, and continues to rotate the spray arm 2 so that the angle between the spray arm 2 and the mounting surface of the water distributor 1 is in the range of 17° - 90°. The water channel is opened, and then the spray arm 2 sprays water to clean the cup. Especially when the secondary spray arm 4 is vertically upward, at this time, the balance between the deep - mouth cup and the spray arm 2 is the best, so that during the cleaning process, the position of the deep - mouth cup is relatively stable and does not shake. After the cleaning is completed, the user slightly rotates the secondary spray arm 4 to the non - working state, then removes the cup, and finally continues to rotate the secondary spray arm 4 until it fits against the mounting surface of the water distributor 1. In summary, the process for the user to clean the deep - mouth cup is relatively convenient, without the need to deliberately turn on the switch. The steps of using the spray arm structure are relatively simple, and the rotatable spray arm 2 enables the spray arm 2 to be retracted against the mounting surface of the water distributor 1, making the overall height of the spray arm structure occupy less space, and thus facilitating the spray arm structure to be adapted to storage spaces such as cupboards.

[0043] Further, in this embodiment, the water distributor 1 includes a first water distribution part 19 and a second water distribution part 20. The first water distribution part 19 is provided with a water distribution groove 21 for forming a first channel 7, and the first water distribution part 19 is also provided with a rotation cavity 8. The first water outlet 5 is opened at one end of the water distribution groove 21 close to the rotation cavity 8. The first water distribution part 19 is also provided with a rotation opening at the rotation cavity 8. The second water distribution part 20 is also provided with a water distribution groove 21 for forming a first channel 7, and the second water distribution groove 21 is also provided with a rotation cavity 8. The first water distribution part 19 and the second water distribution part 20 are bolt - connected.

[0044] The main spray arm 3 includes an arm body part 23 and an arm end part 24. The arm body part 23 and the arm end part 24 are hermetically inserted. The arm end part 24 is located at the rotation cavity 8 of the water distributor 1. The second water inlet 6 is opened on the outer wall of the arm end part 24. One end of the arm end part 24 for connecting the arm body part 23 is just located at the rotation opening, so that the arm end part 24 and the arm body part 23 are inserted at the rotation opening. The arm end part 24 is rotatable in the rotation cavity 8, and the secondary spray arm 4 is integrally formed on the outer wall of the arm body part 23.

[0045] During the assembly process of the spray arm structure, the staff first place the arm end 24 at the rotation cavity 8 of the first water distribution part 19, then insert the arm end 24 and the arm body part 23 into the rotation port of the first water distribution part 19, and finally bolt-connect the first water distribution part 19 and the second water distribution part 20; during use, when the user rotates the spray arm 2 to the working position, the first water outlet 5 communicates with the second water inlet 6, and the water from the external water source enters the water distributor 1 through the first channel 7 on the water distributor 1, and enters the second water inlet 6 of the arm end 24 through the first water outlet 5 communicating with the first channel 7, thereby realizing the water entering the second channel of the spray arm 2; when the user rotates the spray arm 2 to the storage position or non-working position, the second water inlet 6 is not communicated with the first water inlet 25, and the water cannot enter the spray arm 2 from the water distribution pipe. At this time, the spray arm 2 cannot clean the deep cup. At the same time, since both the first water outlet 5 and the second water inlet 6 are located in the water distributor 1, the water flow channel between the first water outlet 5 and the second water inlet 6 can better isolate the outside world and has good sealing performance.

[0046] Further, in this embodiment, a first protrusion 10 is integrally formed in the radial direction at one end of the arm end 24 away from the arm body part 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 is provided with a first groove 9 at a position relative to the first protrusion 10. The shape of the first groove 9 is a quarter circle. The first protrusion 10 is located in the first groove 9. The rotation range of the spray arm 2 is limited by the first protrusion 10, so that the spray arm 2 can only rotate around the water distributor by 0-90°, and the spray arm 2 can rotate around the water distributor 1 by 90°, just making the auxiliary spray arm 4 rotate from the position where it fits the installation surface of the water distributor 1 to the position where the auxiliary spray arm 4 is perpendicular to the installation surface of the water distributor 1.

[0047] Further, in this embodiment, a third protrusion 16 is integrally formed at one end of the arm end 24 away from the arm body part 23. A part of the third protrusion 16 is an arc that cooperates with the rotation cavity 8, and the other part is a protrusion. The third protrusion 16 can not only ensure the tightness of the cooperation between the arm end 24 and the rotation cavity 8, but also does not affect the rotation of the arm end 24 in the rotation cavity 8.

[0048] Further, in this embodiment, two sealing rings 11 are sleeved in the rotation cavity 8 of the arm end 24, 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 rotation cavity 8 is also located between the two sealing rings 11, so that the first water outlet 5, the second water inlet 6 are isolated from other parts of the rotation cavity 8, and the water flow path is through the first channel 7, the part of the rotation cavity 8 between the two sealing rings 11, and the second channel, reducing the influence of water leakage on use.

[0049] Further, in this embodiment, the secondary spray arm 4 includes an upper part 17 and a lower part 18 of the secondary spray arm. The upper part 17 and the lower part 18 of the secondary spray arm are integrally formed. The outer diameter of the lower part 18 of the secondary spray arm is larger than that of the upper part 17 of the secondary spray arm. The cleaning holes 22 are opened in the upper part 17 of the secondary spray arm. The larger outer diameter of the lower part 18 of the secondary spray arm facilitates the stable standing of the secondary spray arm 4 on the one hand, and on the other hand, the upper side of the lower part 18 of the secondary spray arm is convenient for the inverted placement of the deep cup, so that the upper end of the upper part 17 of the secondary spray arm can wash the inner end of the deep cup.

[0050] Further, in this embodiment, a part of the vertical cross-sectional shape of the main spray arm 3 is a semi-circle, and the other part is a rectangle. (When the main spray arm 3 rotates to the storage state, the right part of the vertical cross-sectional shape of the main spray arm 3 is a semi-circle, and the left part is a rectangle; ) When the main spray arm 3 rotates to the working state, the upper part of the vertical cross-sectional shape of the main spray arm 3 is a semi-circle, and the lower part is a rectangle, so that the lower side, the left side and the right side of the main spray arm 3 can all be attached to the mounting surface of the water distributor 1. Therefore, no matter whether the main spray arm 3 rotates to the storage state or the working state, it can be stably attached to the mounting surface of the water distributor 1, thus ensuring the stability of the storage state or the working state.

[0051] Further, in this embodiment, the first water outlet 5 is arc-shaped, and the second water inlet 6 is also arc-shaped. When the secondary spray arm 4 is attached to the mounting surface of the water distributor 1, the second water inlet 6 and the first water outlet 5 do not coincide completely at this time, and at this time, the water distributor 1 and the spray arm 2 are not connected. When the secondary 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 at this time. When the secondary spray arm 4 continues to rotate away from the mounting surface of the water distributor 1, and the angle formed by the secondary spray arm 4 and the mounting surface of the water distributor 1 gradually changes from 17° to 90°, at this time, the arc-shaped second water inlet 6 and the arc-shaped first water outlet 5 gradually coincide, and the water flow sprayed by the secondary spray arm 4 gradually increases. When the arc-shaped second water inlet 6 and the arc-shaped first water outlet 5 coincide completely, the water flow is the largest at this time, and the secondary spray arm 4 just rotates 90°.

[0052] Further, in this embodiment, it further includes a fixed bracket 12. The fixed bracket 12 is rotatably connected to one 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, so that the position of the spray arm 2 is relatively stable and will not shake. Therefore, it is more convenient for the user to rotate the secondary spray arm 4 without considering the shaking of the spray arm 2 in other directions, nor considering that the force applied by the user to rotate the spray arm 2 is converted into force in other directions to affect the rotation effect of the spray arm 2.

[0053] Further, in this embodiment, a second protrusion 13 is integrally formed at one end of the fixing bracket 12 away from the main spray arm 3. A second groove 14 is formed in the second protrusion 13. An inclined surface 15 is formed in the second protrusion 13 near the second groove 14. The second protrusions 13 are arranged in a mirror-image staggered manner on the fixing bracket 12, so that the user can engage the fixing bracket 12 in a storage structure with a strip-shaped structure through the second groove 14 on the second protrusion 13. The strip-shaped structure can be a basket, a bracket, etc. The inclined surface 15 facilitates the disassembly of the fixing bracket 12 from the strip-shaped structure.

[0054] Further, in this embodiment, a basket is further included. The water distributor 1 is connected to the basket. The fixing bracket 12 is clamped to the basket through the second protrusion 13 to fix the water distributor 1 on the basket. The fixing bracket 12 is also located on the basket. The spray arm 2 is rotatably connected to the water distributor 1 and the fixing bracket 12. By storing the water distributor 1 and the spray arm 2 on the basket, it is not only convenient for cleaning and storing the deep cup, but also effectively utilizes the overall space.

[0055] Further, in this embodiment, when the user installs the spray arm structure on the basket, the water distributor 1 is arranged front and back in the basket and is in contact with the left end of the basket, thereby reducing the division of the space in the basket by the water distributor 1 with a certain volume. At the same time, the spray arm 2 is located on the right side of the water distributor 1, and the fixing bracket 12 is located on the right side of the spray arm 2. When the spray arm 2 is in the storage position, the upper part 17 of the auxiliary spray arm is located in the front of the basket, and the lower part 18 of the auxiliary spray arm is located in the back of the basket, facilitating the user to rotate the auxiliary spray arm 4 in front of the basket.

[0056] Further, in this embodiment, the left and right ends of the basket are bent inward to form depressions. The front end of the water distributor 1 is also bent inward, so that the front end of the water distributor 1 is in a "7" shape, and the first water inlet 25 of the water distributor 1 is just located at the depression of the basket. Moreover, the shape of the water distributor 1 fits the left end of the basket, so that the pipeline for connecting to the first water inlet 25 can be placed at the depression of the basket.

[0057] Further, in this embodiment, the horizontal height of the front end of the fixed bracket 12 is less than that of the rear end of the fixed bracket 12. The rear end of the fixed bracket 12 is used for rotational cooperation with the right end of the main spray arm 3. A bracket groove for cooperation with the basket is provided at the lower end of the fixed bracket 12. The second protrusion 13 is located at the left end of the fixed bracket 12. The bracket groove of the fixed bracket 12 enables the fixed bracket 12 to be partially arranged 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 smaller volume on the basis of being able to stably limit the spray arm 2. Furthermore, the entire water distributor 1, spray arm 2, and fixed bracket 12 can occupy a smaller volume inside the basket, and the fixed bracket 12 does not divide the volume inside the basket, causing unnecessary additional volume inside the basket due to space division. Thus, the volume inside the basket can be utilized more efficiently.

[0058] Further, in this embodiment, a protrusion is integrally formed at the position of the main spray arm 3 between the secondary spray arms 4. The protrusion strengthens the strength of the main spray arm 3.

[0059] Further, in this embodiment, a first hook member for connecting with the basket is integrally formed on the lower side of the first water distribution part 19, and the first hook member bends forward. A second hook member is integrally formed at the left end of the second water distribution part 20, and the second hook member bends forward. A third hook member is integrally formed at the left end of the second water distributor 1, and the third hook member bends backward. The position where the third hook member bends is on the same vertical line as the position where the second hook member bends. Thus, when the user rotates the secondary spray arm 4, the first hook member can prevent the water distributor 1 from moving backward, and the second hook member and the third hook member cooperate to connect with the basket, thereby preventing the front-back movement of the water distributor 1.

[0060] Further, in this embodiment, the present invention does not particularly limit the angle formed between the axis of the secondary spray arm 4 and the axis of the main spray arm 3. It is sufficient that those skilled in the art are familiar with the fact that when the main spray arm 3 rotates to the non-working position or the working position, the secondary spray arm 4 can stably place a deep cup, and when the main spray arm 3 rotates to the storage state, the secondary spray arm 4 can fit the installation surface of the water distributor 1. Those skilled in the art can select and adjust according to the specific application situation and product requirements.

[0061] Further, in this embodiment, the present invention does not particularly limit the non-working position range and the working position range of the spray arm 2. It is sufficient that those skilled in the art are familiar with the fact that the spray arm 2 can sleeve a cup in the non-working range, and the spray arm 2 sleeving the cup can work stably with a stable form in the working range. Those skilled in the art can select and adjust according to the specific application situation and product requirements. Preferably, the non-working range is that the secondary spray arm rotates 0 - 17° from the installation surface of the water distributor; preferably, the working range is that the secondary spray arm rotates 17° - 90° from the installation surface of the water distributor.

[0062] Furthermore, in this embodiment, the present invention does not particularly limit the specific shapes of the first channel 7, the second channel, and the third channel, as long as those well-known to those skilled in the art can achieve the water flow from the water distributor 1 to the cleaning holes 22. Those skilled in the art can make selections and adjustments according to specific application scenarios and product requirements.

[0063] It should be noted that, in cases where the embodiments of the present application do not conflict with each other and the technical solutions can coexist, they can be arbitrarily combined into new embodiments.

[0064] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
