Description

Technical Field

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

[0002] In the existing technology, the spray arm structure used for cleaning cups is basically only suitable for cleaning specific types of cups, and cannot cope with cleaning cups of various sizes and shapes. In addition, the existing spray arm structure is relatively complex and inconvenient to assemble, which not only affects the production of the spray arm structure, but also affects the maintenance or replacement of the spray arm structure. Therefore, there is room for further improvement. Utility Model Content

[0003] In view of this, this application provides a spray arm structure for cleaning cups, which can adapt to cleaning cups of different depths and irregular shapes, and its structure is simple, easy to assemble, and convenient for production and maintenance.

[0004] In summary, to broaden the range of cup sizes and types that can be cleaned using the spray arm structure and to optimize the simplicity of the spray arm structure, this application proposes a spray arm structure for cup cleaning.

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

[0006] A spray arm structure for cleaning cups includes a spray pipe and a nozzle assembly. The spray pipe has a spray port, and the nozzle assembly includes a nozzle limiting member and a nozzle. The nozzle portion is located inside the spray port. The nozzle limiting member has a first through hole, and the nozzle limiting member is connected to the spray pipe, such that the nozzle is located between the nozzle limiting member and the spray pipe.

[0007] By adopting the above technical solution, during the assembly process, the user first inserts the nozzle into the spray nozzle, and then connects the nozzle limiting component to the spray pipe, thus completing the assembly. The nozzle is confined between the nozzle limiting component and the spray pipe. The nozzle limiting component restricts the tightness of the connection between the nozzle and the spray nozzle downwards, allowing the nozzle to rotate while preventing water leakage between the nozzle and the spray nozzle. This achieves the simplicity of the spray arm structure, facilitating its production, maintenance, or replacement. At the same time, since the nozzle assembly is directly connected to the spray pipe, and the nozzle is confined between the nozzle limiting component and the spray pipe, the height of the nozzle assembly is limited. This limited height allows the cup to not only fit onto the nozzle assembly but also to contact the mounting surface of the spray pipe, ensuring the cup is securely fixed to the nozzle assembly. This results in a wide range of cup sizes and shapes that can be fitted or placed on the spray arm structure, preventing situations where the cup can only fit onto the nozzle and thus avoids insecure or wobbly connections.

[0008] Preferably, the nozzle includes a mounting part and a nozzle head. The mounting part is connected to the nozzle head. The mounting part has a first channel, and the nozzle head has a second channel. The second channel is arc-shaped. The first channel and the second channel are connected, and a spray hole is formed at the end of the second channel away from the first channel. The position of the first through hole corresponds to the position of the spray hole.

[0009] By adopting the above technical solution, after the water flows into the spray pipe, it enters the second channel of the spray head through the first channel of the installation part, and then sprays out from the spray hole of the spray head. The arc-shaped second channel allows the spray head to rotate continuously under the impact of the water flow. At the same time, the arc-shaped second channel also makes the water flow sprayed from the spray head inclined, that is, the water flow expands outward, thereby making the inner diameter range of the cup that the spray head can clean larger.

[0010] Preferably, the spray pipe is provided with a water outlet pipe at the spray port, and the spray head is located inside the water outlet pipe.

[0011] By adopting the above technical solution, the length of the connection between the nozzle and the water outlet pipe is longer and the contact surface between the nozzle and the water outlet pipe is larger, which is beneficial to the sealing effect of the connection between the nozzle and the water outlet pipe. At the same time, the installation location of the nozzle is far away from the sprinkler pipe, which helps to improve the strength of the sprinkler pipe.

[0012] Preferably, the nozzle has a first protrusion at one end near the mounting portion, and a sealing ring is provided on the water outlet pipe, such that the sealing ring is located between the first protrusion and the water outlet pipe.

[0013] By adopting the above technical solution, the first protrusion makes one end of the spray head relatively flat, which is conducive to the stability of the sealing ring position between the first protrusion and the water outlet pipe. In addition, the first protrusion also increases the contact area between the sealing ring and the spray head, which is conducive to improving the sealing effect.

[0014] Preferably, the nozzle has a second groove at its axis, and the nozzle limiting member has a second protrusion corresponding to the second groove, the second protrusion being located within the second groove.

[0015] By adopting the above technical solution, the position of the nozzle is relatively fixed when the nozzle rotates within the nozzle limiting component. At the same time, the contact area between the nozzle and the nozzle limiting component is reduced, thus reducing the interference of the nozzle limiting component on the rotation of the nozzle.

[0016] Preferably, the nozzle has a second protrusion at its axis, and the nozzle limiting member has a second groove corresponding to the second protrusion, with the second protrusion located in the second groove.

[0017] By adopting the above technical solution, the position of the nozzle is relatively fixed when the nozzle rotates within the nozzle limiting component. At the same time, the contact area between the nozzle and the nozzle limiting component is reduced, thus reducing the interference of the nozzle limiting component on the rotation of the nozzle.

[0018] Preferably, the second groove is conical in shape; the second protrusion is conical in shape.

[0019] By adopting the above technical solution, the nozzle rotates better within the nozzle limiting component, and the force is evenly distributed.

[0020] Preferably, the spray pipe is provided with a snap fastener, and the nozzle limiting component is provided with a snap fastener, and the snap fastener cooperates with the snap fastener.

[0021] By adopting the above technical solution, the nozzle limiting component and the spray pipe can be quickly installed through snap-fit ​​parts and snap-fit ​​parts, which facilitates the production of the spray arm structure and also facilitates the maintenance or replacement of the spray arm structure.

[0022] Preferably, the vertical cross-section of the buckle component is approximately a right triangle, the buckle component has a first inclined surface, the buckle mother component is "7" shaped, the buckle mother component has a second through hole for cooperating with the buckle component, and one end of the buckle mother component also has a second inclined surface, the second inclined surface being parallel to the first inclined surface.

[0023] By adopting the above technical solution, users only need to press down on the nozzle limiting component to complete the installation of the nozzle limiting component and the spray pipe, and only need to pry the nozzle limiting component outward to complete the disassembly of the nozzle limiting component and the spray pipe.

[0024] Preferably, it also includes a water inlet pipe, which is connected to the spray pipe and is arranged vertically upward.

[0025] By adopting the above technical solution, when the spray arm structure is installed in the basket, the water in the upper basket can be accurately entered into the spray pipe through the water inlet pipe, thereby achieving efficient utilization of water resources.

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

[0027] 1. During assembly, the user first inserts the nozzle into the spray nozzle, then connects the nozzle limiting component to the spray pipe to complete the assembly. The nozzle is confined between the nozzle limiting component and the spray pipe. The nozzle limiting component restricts the tightness of the connection between the nozzle and the spray nozzle, allowing the nozzle to rotate while preventing water leakage between the nozzle and the spray nozzle. This achieves the simplicity of the spray arm structure, facilitating its production, maintenance, and replacement. At the same time, because the nozzle assembly is directly connected to the spray pipe and the nozzle is confined between the nozzle limiting component and the spray pipe, the height of the nozzle assembly is limited. This limited height allows the cup to not only fit onto the nozzle assembly but also to contact the mounting surface of the spray pipe, ensuring the cup is securely fixed to the nozzle assembly. This results in a wide range of cup sizes and shapes that can be fitted or placed on the spray arm structure, preventing situations where the cup can only fit onto the nozzle and thus avoids insecure or wobbly connections.

[0028] 2. After the water enters the spray pipe, it passes through the first channel of the installation part and enters the second channel of the spray head, and then sprays out from the spray hole of the spray head. The arc-shaped second channel allows the spray head to rotate continuously under the impact of the water flow. At the same time, the arc-shaped second channel also makes the water flow sprayed from the spray head inclined, that is, the water flow expands outward, thus making the inner diameter range of the cup that the spray head can clean larger.

[0029] 3. The second groove and the second protrusion make the position of the nozzle relatively fixed when the nozzle rotates within the nozzle limiting component, and at the same time reduce the contact area between the nozzle and the nozzle limiting component, thereby reducing the interference of the nozzle limiting component on the rotation of the nozzle.

[0030] 4. This allows water from the upper basket to be precisely fed into the spray pipe through the inlet pipe when the spray arm structure is installed in the basket, thereby achieving efficient utilization of water resources. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] This application discloses a spray arm structure for cleaning cups.

[0041] Reference Figures 1-7 It includes a spray pipe 1 and a nozzle assembly 2. The spray pipe 1 has a spray port on its upper side. The nozzle assembly 2 includes a nozzle limiting member 3 and a nozzle 4. The nozzle 4 is connected to the spray port, and the nozzle limiting member 3 is connected to the spray pipe 1, so that the nozzle 4 is located between the nozzle limiting member 3 and the spray pipe 1.

[0042] The nozzle 4 includes a mounting part 6 and a nozzle head 7. The mounting part 6 is cylindrical, and the nozzle head 7 is approximately an inverted frustum shape. The upper end of the mounting part 6 and the lower end of the nozzle head 7 are integrally formed. The mounting part 6 has a first channel 8 at its axis, and the nozzle head 7 has an arc-shaped second channel 9. One end of the second channel 9 is connected to the first channel 8, and the other end is located at the upper edge of the nozzle 4. The end of the second channel 9 away from the first channel 8 becomes a spray hole 10.

[0043] The upper part of the nozzle limiting member 3 is an inverted circular cup shape. The nozzle limiting member 3 has a second through hole 19 at its upper corner. The position of the second through hole 19 corresponds to the nozzle 10, so that the water flow sprayed from the nozzle 10 can not only be sprayed from the upper side of the nozzle limiting member 3, but also sprayed from the outer wall of the nozzle limiting member 3.

[0044] During the assembly of the spray arm structure, the user first inserts the nozzle 4 into the spray port of the spray pipe 1, and then connects the nozzle limiting member 3 to the spray pipe 1, thus completing the assembly. The nozzle 4 is confined between the nozzle limiting member 3 and the spray pipe 1. The nozzle limiting member 3 downward restricts the tightness of the connection between the nozzle 4 and the spray port, allowing the nozzle 4 to rotate while preventing water leakage between the nozzle 4 and the spray port. After the water flows into the spray pipe 1, it passes through the first channel 8 of the mounting part 6 and enters the second channel 9 of the nozzle head 7, and then sprays out from the spray hole 10 of the nozzle head 7. The arc-shaped second channel 9 allows the nozzle 4 to rotate continuously under the impact of the water flow. At the same time, the arc-shaped second channel 9 also makes the water flow sprayed from the nozzle 4 inclined, that is, the water flow expands outward. This allows the nozzle 4 to clean a wider range of cups with different inner diameters, thus achieving a simpler spray arm structure, facilitating its production, maintenance, and replacement. Furthermore, since the nozzle assembly 2 is directly connected to the spray pipe 1, and the nozzle 4 is confined between the nozzle limiting member 3 and the spray pipe 1, both the heights of the nozzle assembly 2 and the nozzle 4 are limited. Consequently, the cup can not only be fitted onto the nozzle assembly 2 but also contact the mounting surface of the spray pipe 1, ensuring a stable fixation. This results in a wider range of cup sizes and shapes that can be fitted or placed on the spray arm structure, preventing insecure or wobbly fits caused by cups only being able to fit onto the nozzle 4.

[0045] Furthermore, in this embodiment, the spray pipe 1 has an integrally formed water outlet pipe 11 at the spray nozzle. The water outlet pipe 11 minimizes the height of the mounting surface between the nozzle 4 and the spray pipe 1, which not only allows smaller cups to be directly fitted onto the nozzle 4 and the water outlet pipe 11, but also results in a longer insertion length between the nozzle 4 and the water outlet pipe 11 and a larger contact surface between the nozzle 4 and the water outlet pipe 11. This is beneficial to the sealing effect of the connection between the nozzle 4 and the water outlet pipe 11. At the same time, it keeps the mounting point of the nozzle 4 away from the spray pipe 1, reducing the stress on the spray pipe 1 and facilitating the improvement of the strength of the spray pipe 1.

[0046] Furthermore, in this embodiment, the nozzle 7 has a first protrusion 12 integrally formed on the outer wall of one end near the mounting part 6. The end face of the first protrusion 12 is flush with the end face of the water outlet pipe 11. A sealing ring 13 is fitted on the nozzle 4, so that when the nozzle 4 is inserted into the water outlet pipe 11, the sealing ring 13 is located between the first protrusion 12 and the water outlet pipe 11, which increases the sealing stability between the first protrusion 12 and the water outlet pipe 11 and improves the sealing effect at the connection between the first protrusion 12 and the water outlet pipe 11.

[0047] Furthermore, in this embodiment, the nozzle 4 has a second groove 14 on the upper axis of the nozzle head 7, and a second protrusion 15 is integrally formed on the axis of the inner end of the nozzle limiting member 3 (i.e., corresponding to the second groove 14). The second protrusion 15 is located in the second groove 14, and only the second protrusion 15 contacts the nozzle 4 at the inner end of the nozzle limiting member 3. This makes the position of the nozzle 4 relatively fixed when the nozzle 4 rotates within the nozzle limiting member 3, and also reduces the contact area between the nozzle 4 and the nozzle limiting member 3, thereby reducing the interference of the nozzle limiting member 3 on the rotation of the nozzle 4.

[0048] Furthermore, in this embodiment, the second groove 14 can also be formed on the nozzle limiting member 3, and the second protrusion 15 is integrally formed on the nozzle head 7.

[0049] Furthermore, in this embodiment, the second groove 14 is conical in shape; the second protrusion 15 is conical in shape, so that the nozzle 4 rotates better within the nozzle limiting member 3 and the force is evenly distributed; the second protrusion 15 may also be cylindrical in the upper part and conical in the lower part.

[0050] Furthermore, in this embodiment, snap fasteners 16 are integrally formed on both sides of the spray pipe 1, and snap fasteners 17 are integrally formed on both sides of the lower part of the nozzle limiting member 3. The snap fasteners 16 and snap fasteners 17 cooperate to allow the nozzle limiting member 3 and the spray pipe 1 to be quickly installed through the snap fasteners 16 and snap fasteners 17, which facilitates the production of the spray arm structure and also facilitates the maintenance or replacement of the spray arm structure; the positions of the snap fasteners 16 and snap fasteners 17 can also be interchanged.

[0051] Furthermore, in this embodiment, the vertical cross-section of the snap fastener 16 is approximately a right triangle. The snap fastener 16 has a first inclined surface 18, and the snap fastener 17 is shaped like a "7". The upper end of the snap fastener 17 is integrally formed with the two sides of the upper part of the nozzle limiting member 3. A second through hole 19 for cooperating with the snap fastener 16 is provided at the corner of the snap fastener 17. A second inclined surface 20 is also provided on the inner side of the lower end of the snap fastener 17. The second inclined surface 20 is parallel to the first inclined surface 18. The user only needs to press down on the nozzle limiting member 3 to complete the installation of the nozzle limiting member 3 and the spray pipe 1. At the same time, the user only needs to pry open the nozzle limiting member 3 outward to complete the disassembly of the nozzle limiting member 3 and the spray pipe 1.

[0052] Furthermore, in this embodiment, the spray pipe 1 has a square base 22 integrally formed around the water outlet pipe 11. The square base 22 is shaped like a tray. The water outlet pipe 11 is located inside the square base 22, and the sealing ring 13 is also located inside the square base 22. The nozzle limiting member 3 has a sealing protrusion 23 integrally formed on the upper side of the snap-fit ​​female member 17, so that the sealing protrusion 23 and the upper part of the snap-fit ​​female member 17 cover the square base 22 and seal the square base 22.

[0053] Furthermore, in this embodiment, the spray arm structure also includes a water inlet pipe 21, which is connected to the spray pipe 1. The water inlet pipe 21 is set vertically upward, so that when the spray arm structure is installed in the basket, the water in the upper basket can be accurately entered into the spray pipe 1 through the water inlet pipe 21, thereby achieving efficient utilization of water resources.

[0054] Furthermore, in this embodiment, the present invention does not impose any particular restrictions on the specific structure and number of the nozzle 4. Any nozzle 4 that can achieve the rotation function, as well known to those skilled in the art, can be used. Those skilled in the art can select and adjust according to the specific application and product requirements.

[0055] Furthermore, in this embodiment, the present invention does not impose any particular restrictions on the connection structure between the nozzle 4 and the spray port of the spray pipe 1. Any structure known to those skilled in the art that enables the nozzle 4 to rotate on the spray port of the spray pipe 1 can be used. Those skilled in the art can select and adjust the connection structure according to the specific application and product requirements.

[0056] Furthermore, in this embodiment, the present invention does not impose any particular restrictions on the connection structure between the nozzle limiting component 3 and the spray pipe 1. Any structure known to those skilled in the art that can achieve a stable connection between the nozzle limiting component 3 and the spray pipe 1 is acceptable. Those skilled in the art can select and adjust the structure according to the specific application and product requirements.

[0057] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
