[0054] Embodiment 1

[0055] like Figures 1 to 14 As shown, this embodiment provides an auxiliary spray arm assembly, which can adjust the position of enhanced washing according to user needs, improve the washing effect, and provide a good user experience. The auxiliary spray arm assembly includes a first mounting seat 1 and a spray pipe 2.

[0056] Among them, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The first mounting base 1 is arranged on the water collection tank 100 of the dishwasher, and a first water outlet channel 11 is arranged on the first mounting base 1, and the first water outlet channel 11 is communicated with the water outlet of the water collection tank 100. The first end of the spray pipe 2 is rotatably connected to the first water outlet channel 11, and the rotation angle of the spray pipe 2 is adjustable. The second end of the spray pipe 2 is provided with a spray head assembly, and the spray head assembly is provided with a water spray hole.

[0057] Figure 5 FIG. 2 is a schematic diagram of a first rotation range of the spray pipe. The spray pipe 2 can rotate around the axis O of the first water outlet channel 11. Figure 5 The area shown by the middle dotted line is the rotation range of the spray pipe 2. By rotating the spray pipe 2, the spray head assembly can be adjusted to different positions at the bottom of the inner tank 200, thereby changing the enhanced flushing position.

[0058] The auxiliary spray arm assembly provided in this embodiment is used when the dishwasher is performing a washing program, after the water diversion valve 400 is connected to the water diversion port (such as Fig. 9 As shown), water flows through the water diversion port, the first water outlet channel 11 and the spray pipe 2 in sequence to reach the nozzle assembly, and the water flows through the water spray hole to the tableware to be washed, so as to achieve the purpose of enhanced flushing. By adjusting the rotation angle of the spray pipe 2 relative to the first mounting seat 1, the placement position of the nozzle assembly in the inner tank 200 can be adjusted, thereby adjusting the flushing position of the nozzle assembly to enhance the flushing of tableware at different positions and eliminate the cleaning dead corners of the dishwasher. In other words, the auxiliary spray arm assembly can adjust the placement position of the nozzle assembly according to the placement position of the tableware and the washing requirements, so as to locally enhance the flushing of the tableware that needs enhanced washing, so as to make the cleaning mode of the nozzle assembly more diversified, and effectively improve the user experience of the dishwasher.

[0059] In this embodiment, refer to Figure 3 , Figure 4 and Fig. 9 The water collection tank 100 is provided with three water outlets, and the first mounting seat 1 is also provided with a third water outlet channel 14 connected to the bottom spray arm of the dishwasher and a fourth water outlet channel 15 connected to the inner water pipe 300. The inner water pipe 300 is used to connect the middle spray arm and the top spray arm of the dishwasher. The three water outlets are connected to the first water outlet channel 11, the third water outlet channel 14 and the fourth water outlet channel 15 in a one-to-one correspondence. After the washing pump of the dishwasher is started, the water collected in the water collection tank 100 can be passed into the valve cavity of the water outlet valve 400, and then the water outlet valve 400 distributes it to each spray arm and the nozzle assembly through the water outlet to achieve cyclic flushing.

[0060] Furthermore, the water diversion port connected to the bottom spray arm is connected to the water diversion port connected to the first water outlet channel 11. When the water diversion valve is connected to the water diversion port connected to the bottom spray arm, the first water outlet channel 11 conducts water flow, so that the nozzle assembly can spray washing water simultaneously with the bottom spray arm.

[0061] Optionally, see Figure 3 , Figure 7 and Figure 8 The first end of the spray pipe 2 is bent to form a plug-in portion 21, which is inserted into the water outlet end of the first water outlet channel 11 and rotatably matched with the first water outlet channel 11. That is, the spray pipe 2 is L-shaped, and the short end of the L-shaped spray pipe 2 is the above-mentioned plug-in portion 21. In this way, the plug-in portion 21 of the spray pipe 2 is coaxial with the first water outlet channel 11, so that the spray pipe 2 can rotate around the axis of the first water outlet channel 11, which is convenient for adjusting the rotation angle of the spray pipe 2 and can ensure the connection stability between the spray pipe 2 and the first mounting seat 1.

[0062] Continue reading Figure 3 , Figure 7 and Figure 8 , the auxiliary spray arm assembly also includes a flexible seal 6, which is sealed and filled between the outer peripheral wall of the plug-in portion 21 and the inner wall of the first water outlet channel 11, and the plug-in portion 21 is rotatably matched with the flexible seal 6. In this embodiment, the flexible seal 6 is interference-fitted with the plug-in portion 21 and the inner wall of the first water outlet channel 11 to ensure the stability of the rotational connection between the spray pipe 2 and the first mounting seat 1 and prevent the plug-in portion 21 from being separated from the first water outlet channel 11. At the same time, the provision of the flexible seal 6 can make the spray pipe 2 and the first water outlet channel 11 sealed and connected to prevent water leakage and ensure sufficient water pressure at the spray head assembly. In addition, when the spray pipe 2 is rotated, the flexible seal 6 can produce a certain deformation to adapt to the rotation of the spray pipe 2, ensure that the spray pipe 2 is always in flexible contact with the inner wall of the first water outlet channel 11, and avoid interfering with the rotation of the spray pipe 2.

[0063] Exemplarily, the flexible sealing member 6 is a rubber sleeve, which is sleeved on the plug-in portion 21 . During assembly, the rubber sleeve is inserted into the first water outlet channel 11 together with the plug-in portion 21 , and the rubber sleeve is interference fit with the inner wall of the first water outlet channel 11 .

[0064] Optionally, a preset gap is maintained between the outer peripheral wall of the plug-in portion 21 and the inner wall of the first water outlet channel 11, so that the spray pipe 2 can rotate by a preset angle in a preset plane, and the preset plane is perpendicular to the plane where the first mounting seat 1 is located. That is, the spray pipe 2 can rotate in a plane parallel to the first mounting seat 1 (such as Figure 5 ), and can rotate a certain angle (as shown) in a preset plane perpendicular to the first mounting base 1. Figure 6As shown). Since the bottom wall of the inner tank 200 of the dishwasher usually has a certain slope, so that the washing water is collected in the water collection tank 100 in the middle of the inner tank 200, when the spray pipe 2 is rotated and adjusted, the second end of the spray pipe 2 (i.e., the end where the spray head assembly is installed) will have a certain upward and downward displacement relative to the first end. By reserving a preset gap between the plug-in portion 21 and the inner wall of the first water outlet channel 11, the spray pipe 2 can be rotated up and down within a preset plane by a certain angle ( Figure 6 The direction indicated by the middle arrow is the rotation direction of the spray pipe 2 within the preset plane), thereby adapting to the slope design of the bottom of the inner tank 200 and ensuring smooth adjustment of the rotation angle of the spray pipe 2.

[0065] In this embodiment, the flexible seal 6 seals and fills the above-mentioned preset gap, so that when the spray pipe 2 rotates in the preset plane, the plug-in portion 21 can squeeze the flexible seal 6 to produce deformation, thereby preventing the plug-in portion 21 from interfering with the inner wall of the first water outlet channel 11, thereby ensuring good sealing. Figure 7 As shown in FIG. 1 , it is a schematic diagram of the spray pipe 2 rotating to the first state, that is, when the spray pipe 2 is lifted up to a certain angle, the flexible seal 6 is deformed under the extrusion of the plug-in portion 21. Figure 8 , which is a schematic diagram of the spray pipe 2 rotating to the second state, that is, when the spray pipe 2 rotates downward by a certain angle, the flexible sealing member 6 is deformed under the extrusion of the plug-in portion.

[0066] Exemplarily, the above-mentioned preset angle is designed according to the slope of the bottom of the inner tank 200. For example, if the slope of the inner tank 200 is 3°, the range of the preset angle can be 3° to 5°. The preset gap is adaptively designed according to the slope of the bottom of the inner tank 200 and the diameter size of the plug-in portion 21. For example, the preset gap is 3mm to 6mm. It should be noted that the specific values ​​of the above-mentioned preset angle range and preset gap size are adaptively adjusted and set according to parameters such as the size specifications of the inner tank 200 and the spray pipe 2, and are not limited to the numerical range listed in this embodiment.

[0067] Optionally, the nozzle assembly is rotatably connected to the second end of the spray pipe 2, and the rotation angle of the nozzle assembly relative to the spray pipe 2 is adjustable. That is, the nozzle assembly can rotate with the spray pipe 2 as the rotation axis, and the direction of the water flow sprayed from the water spray hole can be changed by adjusting the rotation angle of the nozzle assembly, thereby adjusting the flushing angle of the nozzle assembly, so that the flushing mode of the nozzle assembly is more diverse.

[0068] Optionally, see Figure 2 and Figure 3The nozzle assembly includes an auxiliary nozzle 3 and a second mounting seat 4. The auxiliary nozzle 3 is provided with a water spray hole. The second mounting seat 4 is provided with a second water outlet channel 41. The second end of the spray pipe 2 is connected to the water inlet end of the second water outlet channel 41. The auxiliary nozzle 3 is installed on the second mounting seat 4, and the water spray hole can be connected to the water outlet end of the second water outlet channel 41. The second mounting seat 4 is provided so that the spray pipe 2 and the auxiliary nozzle 3 are detachably installed. The spray pipe 2 can be processed and manufactured separately. In the later stage, only the two ends of the spray pipe 2 need to be assembled with the first mounting seat 1 and the second mounting seat 4 respectively, which reduces the processing difficulty of the spray pipe 2 and lowers the maintenance cost. The first end and the second end mentioned above refer to the two ends of the spray pipe 2 respectively.

[0069] In an optional embodiment, the second mounting seat 4 of the spray head assembly is rotatably connected to the second end of the spray pipe 2, that is, the second end of the spray pipe 2 is inserted into the second water outlet channel 41 and rotatably cooperates with the second water outlet channel 41 to achieve an adjustable rotation angle of the second mounting seat 4 relative to the spray pipe 2, thereby adjusting the water spraying direction of the water spray hole on the auxiliary spray head 3.

[0070] For example, the second end of the spray pipe 2 is covered with a rubber sleeve, which is inserted into the second water outlet channel 41 together with the second end of the spray pipe 2. The spray pipe 2 and the rubber sleeve are rotatably matched, and the rubber sleeve is interference-fitted with the inner wall of the second water outlet channel 41, ensuring that the spray pipe 2 and the second water outlet channel 41 are in flexible contact, which is conducive to adjusting the rotation angle of the spray head assembly. At the same time, the rubber sleeve can make the spray pipe 2 and the second water outlet channel 41 well sealed to prevent water leakage.

[0071] In another optional embodiment, the spray head assembly can also be fixedly connected to the spray pipe 2. Figure 3 The second end of the spray pipe 2 is detachably fixed to the water inlet end of the second water outlet channel 41 by a fastener 7, see Fig.11 and Fig.12 The second mounting base 4 is provided with a connecting column 42, and a connecting hole 421 communicating with the second water outlet channel 41 is opened on the connecting column 42. The fastener 7 is passed through and connected to the connecting hole 421, and is pressed against the spray pipe 2. The spray pipe 2 is limited to the second water outlet channel 41 by the fastener 7 pressing, and is firmly fixed. There is no need to open a hole on the spray pipe 2, which simplifies the processing procedure of the spray pipe 2 and reduces the processing cost.

[0072] Exemplarily, the fastener 7 is a screw, and the connecting hole 421 is a threaded hole. The screw is screwed into the threaded hole until the end of the screw presses against the spray pipe 2, and the disassembly and assembly operations are simple.

[0073] Optionally, the tightening direction of the fastener 7 is perpendicular to the extension direction of the spray pipe 2. That is, the force direction of the fastener 7 is perpendicular to the length direction of the spray pipe 2. Such a setting can firmly tighten the spray pipe 2 in the second water outlet channel 41, thereby improving the fixing reliability of the spray pipe 2.

[0074] Optionally, an adsorbent is provided on the second mounting seat 4, and the adsorbent is configured to be detachably adsorbed on the inner wall of the inner tank 200 of the dishwasher. The second mounting seat 4 is fixed at a designated position of the inner tank 200 by the adsorbent, which can ensure the installation stability of the auxiliary nozzle 3 and improve the enhanced flushing effect of the auxiliary nozzle 3.

[0075] In an alternative embodiment, see Figure 3 and Fig.10 The adsorption member includes a magnetic member 5 disposed on the second mounting seat 4. The inner container 200 is made of a magnetic material, and the magnetic member 5 can be magnetically attracted to the inner wall of the inner container 200. The second mounting seat 4 and the auxiliary nozzle 3 are fixed by magnetic attraction, and the position adjustment is convenient, and the second mounting seat 4 and the auxiliary nozzle 3 can be firmly fixed in the inner container 200. The magnetic material can be stainless steel, as long as it can achieve magnetic attraction with the magnetic member 5.

[0076] For example, see Fig.10 and Fig.11 , the magnetic attraction member 5 is a bar magnet, the cross section of the bar magnet is U-shaped, so as to form a slot on the bar magnet; the second mounting seat 4 is provided with a receiving slot 43, and the side wall of the receiving slot 43 is provided with a bar through hole 431, so as to form a clamping rib 432 matching the size of the slot on the second mounting seat 4, the slot of the bar magnet is engaged with the clamping rib 432, and one side of the bar magnet is clamped into the bar through hole 431, so as to realize the clamping of the bar magnet on the second mounting seat 4, which is convenient for disassembly and assembly. Further, referring to Fig.10 In the middle position, the bottom surface of the bar magnet is flush with the bottom surface of the second mounting base 4, so that the bar magnet can directly contact the inner wall of the inner liner 200 to ensure firm magnetic attraction.

[0077] In another optional embodiment, the adsorbent includes a suction cup disposed on the second mounting seat 4, and the suction cup can be adsorbed on the inner wall of the inner liner 200. That is, the position of the second mounting seat 4 is fixed by adsorbing the suction cup, so that the placement position of the auxiliary nozzle 3 can be adjusted. When the adsorbent is a suction cup, the inner liner 200 can be made of metal material or plastic material.

[0078] Optionally, the auxiliary nozzle 3 is rotatably mounted on the second mounting seat 4, and a plurality of water spray holes are provided on the auxiliary nozzle 3, and the plurality of water spray holes have a plurality of water outlet modes. By rotating the auxiliary nozzle 3 to make a certain water spray hole connected to the water outlet end of the second water outlet channel 41, the water outlet mode of the auxiliary nozzle 3 can be adjusted, so that the flushing function of the auxiliary nozzle 3 is more diversified to meet the different washing needs of users.

[0079] In this embodiment, refer to Fig.10 and Fig.12 , a mounting groove 44 is provided on the second mounting seat 4, and a rotating portion 33 is provided on the auxiliary nozzle 3, and the rotating portion 33 is inserted into the mounting groove 44 and rotatably cooperates with the mounting groove 44. The rotational cooperation between the rotating portion 33 and the mounting groove 44 realizes the rotation of the auxiliary nozzle 3 relative to the second mounting seat 4, so that any one of the water spray holes is connected to the second water outlet channel 41 on the second mounting seat 4. The position of the water spray hole on the auxiliary nozzle 3 is adjusted by rotation, and the operation is simpler and more convenient. Exemplarily, the rotating portion 33 is set at the center position of the auxiliary nozzle 3, so that the rotation of the auxiliary nozzle 3 is more stable.

[0080] Further, see Fig.10 and Fig.13 The rotating part 33 includes a rotating pin 331 disposed on the auxiliary nozzle 3 and a plurality of elastic clamping parts 332. The plurality of elastic clamping parts 332 are circumferentially arranged around the outer periphery of the rotating pin 331. Fig.10 and Fig.12 A hollow plug post 45 is convexly arranged in the middle of the mounting groove 44, and the rotation pin 331 is inserted into the cavity of the hollow plug post 45 and rotates with the cavity. A plurality of elastic clamping parts 332 are hooked and clamped on the edge of the notch of the mounting groove 44 and rotate with the mounting groove 44 to realize the rotation connection between the auxiliary nozzle 3 and the second mounting seat 4. Each elastic clamping part 332 includes a connected elastic cantilever 3321 and a hooking part 3322. During the process of inserting the elastic clamping part 332 into the mounting groove 44, the elastic cantilever 3321 is elastically deformed. After being inserted into place, the hooking part 3322 is hooked and clamped on the edge of the notch of the mounting groove 44. The hooking part 3322 can limit the rotation pin 331 axially in the mounting groove 44, prevent the rotation pin 331 from being separated from the cavity of the hollow plug post 45, and ensure the rotation stability of the auxiliary nozzle 3.

[0081] For example, the outer wall of each hook portion 3322 is designed as a conical surface, which facilitates the insertion of the elastic clamping portion 332 into the installation groove 44 and simplifies assembly. Fig.10 and Fig.12 As shown, the slot opening of the installation slot 44 is circular, and the cross-sectional dimension of the inner space of the installation slot 44 is larger than the slot opening dimension so as to accommodate the hook portions 3322 of the plurality of elastic clamping portions 332 .

[0082] Optionally, the rotating pin 331 and the multiple elastic clamping parts 332 are all integrally formed on the auxiliary nozzle 3. When the rotating pin 331 and the multiple elastic clamping parts 332 are inserted into the installation slot 44, the elastic cantilevers 3321 of the multiple elastic clamping parts 332 can be elastically deformed in the direction close to the rotating pin 331. After the rotating pin 331 and the multiple elastic clamping parts 332 are inserted into place, the elastic cantilever 3321 returns to its original state, so that the hook part 3322 is clamped on the edge of the slot of the installation slot 44 (such as Fig.10 shown).

[0083] In this embodiment, Fig.10 , Fig.11 and Fig.12 As shown, a water outlet nozzle 46 is convexly provided on the second mounting seat 4, and the water outlet end of the second water outlet channel 41 is the water outlet channel of the water outlet nozzle 46. The plurality of water spray holes include a water spray hole 1 31 and a water spray hole 2 32, the water spray hole 1 31 has a first water outlet mode, the water spray hole 2 32 has a second water outlet mode, and the water spray hole 1 31, the water spray hole 2 32 and the water outlet nozzle 46 are all located on a circumference with the rotating pin 331 as the center. Since the auxiliary nozzle 3 rotates with the rotating pin 331 as the central axis, the water spray hole 1 31, the water spray hole 2 32 and the water outlet nozzle 46 are arranged on the same circumference, so that the water spray hole 1 31 and the water spray hole 2 32 can automatically align with the water outlet nozzle 46 after the auxiliary nozzle 3 rotates, ensuring that the water spray hole 1 31 and the water spray hole 2 32 spray water normally. The water spray hole 1 31 and the water spray hole 2 32 are designed as different first water outlet modes and second water outlet modes, and water can be discharged from the water spray hole 1 31 or the water spray hole 2 32 according to user needs.

[0084] For example, the first water spray hole 31 is a straight spray hole, and the water flow it sprays is a straight spray flow, and the second water spray hole 32 is a shower hole, and the water flow it sprays is a scattered water flow. In other embodiments, the number of water spray holes and the water outlet mode of the water spray holes can be adaptively increased or decreased as needed, and are not limited to the number and type of water spray holes listed in this embodiment.

[0085] Optionally, see Fig.13 and Fig.14, the auxiliary nozzle 3 is recessed with a first limiting groove 34, a second limiting groove 35 and a third limiting groove 36 on one side facing the second mounting seat 4. The first limiting groove 34, the second limiting groove 35 and the third limiting groove 36 are spaced apart and distributed on the same circumference. The water outlet 46 can selectively be inserted into one of the first limiting groove 34, the second limiting groove 35 and the third limiting groove 36. The water inlet end of the water spray hole 1 31 is located in the first limiting groove 34, and the water inlet end of the water spray hole 2 32 is located in the second limiting groove 35. When the auxiliary nozzle 3 is rotated until the water outlet 46 is inserted into the third limiting groove 36, the auxiliary nozzle 3 does not discharge water. The provision of the first limiting groove 34, the second limiting groove 35 and the third limiting groove 36 can enable the auxiliary nozzle 3 to stay stably in the corresponding position, ensuring that the gear adjustment of the auxiliary nozzle 3 is more precise. Specifically, when the water outlet 46 is inserted into the first limiting groove 34 (such as Fig.10 As shown in the figure, the second water outlet channel 41 is connected to the water spray hole 1 31, and the water spray hole 1 31 can discharge water; when the water outlet nozzle 46 is inserted into the second limiting groove 35, the second water outlet channel 41 is connected to the water spray hole 2 32, and the water spray hole 2 32 can discharge water. When the water outlet nozzle 46 is inserted into the third limiting groove 36, the third limiting groove 36 can block the second water outlet channel 41, and the auxiliary nozzle 3 cannot discharge water at this time, that is, the enhanced flushing function of the dishwasher is turned off.

[0086] Optionally, a guide surface is provided at the end of the water outlet 46, and when the auxiliary nozzle 3 rotates, the water outlet 46 slides through the guide surface to get into or out of one of the first limiting groove 34, the second limiting groove 35, and the third limiting groove 36. The provision of the guide surface enables the water outlet 46 to smoothly get into or out of the first limiting groove 34 (the second limiting groove 35 or the third limiting groove 36), thereby preventing interference with the rotation of the auxiliary nozzle 3. Exemplarily, the guide surface is a chamfered surface or an arc surface processed at the end of the water outlet 46.

[0087] Optionally, see Fig.10 and Fig.13 A support portion 37 is provided on one side of the auxiliary nozzle 3 facing the first mounting seat 1. The support portion 37 is located on the periphery of the plurality of elastic clamping portions 332. The support portion 37 is used to support and contact with the top surface of the second mounting seat 4. The provision of the support portion 37 can make the auxiliary nozzle 3 more balanced in force, prevent the auxiliary nozzle 3 from being displaced when rotating, and improve the rotation stability. The protruding height of the support portion 37 is less than the height of the water outlet 46, so that the water outlet 46 can be effectively inserted into the first limiting groove 34 (the second limiting groove 35 or the third limiting groove 36), ensuring that the water outlet of the water spray hole 1 31 (the water spray hole 2 32) is normal, and ensuring that the third limiting groove 36 can seal the water outlet 46 tightly.

[0088] In this embodiment, the mounting groove 44 and the water outlet nozzle 46 are located in the same plane on the second mounting seat 4, the first limiting groove 34, the second limiting groove 35 and the third limiting groove 36 have the same recessed depth, and the difference between the raised height of the water outlet nozzle 46 and the recessed depth of the first limiting groove 34 is the same as the raised height of the support portion 37. This ensures that the auxiliary nozzle 3 is placed horizontally relative to the second mounting seat 4 after installation, and the auxiliary nozzle 3 is evenly stressed and rotates stably.

[0089] Exemplarily, the support portion 37 is annular, coaxially and spaced apart from the periphery of the rotating pin 331 , and provides stable support. In other embodiments, the support portion 37 may also be two semi-annular structures symmetrically disposed on both sides of the rotating pin 331 .

[0090] Optionally, see Fig.13 and Fig.14 A plurality of contact protrusions 38 are arranged at intervals along the circumference of the auxiliary nozzle 3, see Fig.11 and Fig.12 An elastic arm 47 is provided on the second mounting seat 4. When the auxiliary nozzle 3 rotates, the elastic arm 47 can elastically contact with any contact protrusion 38. With such a configuration, during the rotation of the auxiliary nozzle 3, the contact protrusion 38 contacts the elastic arm 47 to elastically deform the elastic arm 47. When the elastic arm 47 slides away from the previous contact protrusion 38 and is stuck in the groove between the two adjacent contact protrusions 38, the elastic arm 47 rebounds and touches the auxiliary nozzle 3 to generate vibration, thereby providing contact feedback to the user to prompt the user of the rotation position of the auxiliary nozzle 3, so that the gear adjustment of the auxiliary nozzle 3 is more precise.

[0091] Further, see Fig.10 , Fig.11 and Fig.12 The elastic arm 47 is provided with an indicating protrusion 471, which is configured to indicate the current position of the auxiliary nozzle 3, so that the user can judge which gear the auxiliary nozzle 3 is currently in, thereby accurately adjusting the water outlet mode. Fig.10 and Fig.14,, the side of the auxiliary nozzle 3 facing away from the second mounting seat 4 is divided into a first area, a second area and a third area, and the three areas correspond one by one to the first limiting groove 34, the second limiting groove 35 and the third limiting groove 36 below the auxiliary nozzle 3, the water outlet end of the water spray hole 1 31 is located in the middle position of the first area, the water outlet end of the water spray hole 2 32 is located in the middle position of the second area, and an indicator mark 30 is set in the middle position of the third area, and the indicator mark 30 is used to indicate the closed position of the auxiliary nozzle 3 assembly. Stop slots 39 are provided on the edge of the auxiliary nozzle 3 at the middle position corresponding to the first area, the middle position corresponding to the second area, and the middle position corresponding to the third area. When the auxiliary nozzle 3 rotates until the water outlet 46 is inserted into the first limiting slot 34 (the second limiting slot 35, the third limiting slot 36), the elastic arm 47 is inserted into the corresponding stop slot 39. In this way, the auxiliary nozzle 3 can be limited from rotating in the absence of external force or accidental touch, thereby ensuring that the water outlet 46 is accurately aligned with the first limiting slot 34 (the second limiting slot 35 or the third limiting slot 36).

[0092] In this embodiment, the elastic arm 47 and the water outlet 46 are located on the same straight line. In this arrangement, when the elastic arm 47 is inserted into the stop slot 39 corresponding to the water spray hole 1 31 (water spray hole 2 32, indicator mark 30), the indicator protrusion 471 just points to the water spray hole 1 31 (water spray hole 2 32, indicator mark 30), which can more intuitively indicate the specific gear position of the auxiliary nozzle 3, and the user experience is good. For example, the indicator mark 30 is an "OFF" mark.

[0093] Furthermore, the raised surface of the contact protrusion 38 is a smooth transition surface, and the smooth transition between two adjacent contact protrusions 38 is conducive to the separation of the contact protrusion 38 and the elastic arm 47, thereby improving the smoothness of the rotation of the auxiliary nozzle 3.

[0094] See also Fig.10 When the auxiliary nozzle 3 stops rotating, the elastic arm 47 is stuck in a certain stop slot 39, and the indicating protrusion 471 is hooked on the side of the auxiliary nozzle 3 facing away from the second mounting seat 4, so that the auxiliary nozzle 3 can be further restricted from rotating accidentally.

[0095] Optionally, see Fig.11 and Fig.12 A reinforcing rib 472 is provided at the connection between the elastic arm 47 and the second mounting seat 4. The provision of the reinforcing rib 472 can increase the connection strength between the elastic arm 47 and the second mounting seat 4 and prevent the elastic arm 47 from breaking. Exemplarily, the reinforcing rib 472 is a triangular plate connected between the second mounting seat 4 and the elastic arm 47, and the connection is more stable.

[0096] In this embodiment, the auxiliary nozzle 3 is a nearly circular structure, and the outer circumference of the circular structure is sequentially concave and convex to form the above-mentioned multiple contact protrusions 38. In other embodiments, the auxiliary nozzle 3 can also be designed as a triangle or other polygonal structure.

The plurality of limit slots 1321 are distributed at intervals on a preset circumference with the rotation center of the spray pipe 2 as the center, and the spray pipe 2 can be selectively inserted into any limit slot 1321. After the rotation angle of the spray pipe 2 is adjusted, the position of the spray pipe 2 can be fixed by simply inserting the spray pipe 2 into the limit slot 1321 corresponding to the angle, so that the position adjustment of the auxiliary nozzle 3 is convenient and quick.

[0100] The method of fixing the spray pipe 2 by the support frame 13 and the limiting slot 1321 in this embodiment can be applicable to the inner liner 200 of any material. The inner liner 200 can be made of non-magnetic material, so that the auxiliary spray arm assembly has a wider application range.

[0101] Optionally, the support frame 13 is a support plate 131 cantilevered from the first mounting seat 1 , a support rib 132 is protruded from the support plate 131 , and a plurality of the above-mentioned limiting slots 1321 are spaced apart from each other on the support rib 132 .

[0102] For example, four limit slots 1321 are provided on the support ribs 132 of the support frame 13, which can realize four-level angle adjustment of the spray pipe 2. In other embodiments, the number of limit slots 1321 can be adaptively increased or decreased according to actual needs, and the distance between two adjacent limit slots 1321 can be adjusted to change the angle of each level of adjustment of the spray pipe 2.
