[0008] In the preferred embodiment of the above-mentioned spraying device, the main body is provided with a self-locking structure, the self-locking structure abuts against the second end of the first hole structure along the first direction, and the connecting part abuts against the second end of the second hole structure along the first direction.

[0009] In the preferred embodiment of the above-mentioned spraying device, the two sides of the connecting part abut against the two inner walls of the second hole structure that are opposite to each other along the second direction.

[0010] In the preferred embodiment of the above-mentioned spraying device, the main body includes a plate-shaped body and a handle disposed on the plate-shaped body. The handle is located on the side of the plate-shaped body away from the snap-fit ​​portion. The snap-fit ​​portion is connected to the plate-shaped body through the connecting portion and forms the snap-fit ​​groove between the plate-shaped body and the plate-shaped body.

[0011] In the preferred embodiment of the above-mentioned spraying device, the connecting part is arranged perpendicularly to the plate-shaped body, and the snap-fit ​​part is arranged parallel to the plate-shaped body; and / or

The limiting part can cooperate with the limiting structure to fix the water inlet pipe in the mounting hole.

[0016] In the preferred embodiment of the above-mentioned spraying device, an annular limiting platform is provided on the inner wall of the mounting hole in the circumferential direction. The limiting structure is an annular limiting plate provided on the water inlet pipe. The annular limiting platform abuts against one side of the annular limiting plate, and the limiting part abuts against the other side of the annular limiting plate.

[0017] In addition, the present invention also provides a dishwasher including the spray device described above.

[0018] Those skilled in the art will understand that the technical solution of the present invention provides a spraying device, including a spraying arm and a water inlet pipe connected to the spraying arm. The spraying device also includes a mounting base and a locking member detachably connected to the mounting base. The mounting base has a mounting hole, one end of the water inlet pipe is inserted into the mounting hole, the mounting base is also provided with a first snap-fit ​​structure, and the locking member is provided with a second snap-fit ​​structure. The first snap-fit ​​structure and the second snap-fit ​​structure engage to fix the locking member to the mounting base, thereby fixing the water inlet pipe in the mounting hole through the locking member. With the above technical solution, the present invention makes the installation and removal of the water inlet pipe of the spraying device more convenient. Specifically, the present invention adds a locking member, which is fixed to the mounting base through a simple snap-fit ​​engagement of the first snap-fit ​​structure and the second snap-fit ​​structure. The locking member enables quick connection and separation between the water inlet pipe and the mounting base, greatly simplifying the installation and removal process and improving the efficiency of maintenance and replacement. In addition, the snap-fit ​​structure design of the present invention also ensures the stability of the water inlet pipe after installation. Through the interlocking of the first and second snap-fit ​​structures, the water pipe can be firmly fixed in the installation hole, thereby effectively preventing loosening or falling off due to water flow impact or machine vibration during use, and ensuring the stable operation of the sprinkler system.

[0019] Furthermore, the mounting base of the present invention is also provided with a snap-fit ​​hole, at least a portion of the edge of the snap-fit ​​hole forming a first snap-fit ​​structure, and a second snap-fit ​​structure being a slot provided on the locking member. The locking member is installed in the snap-fit ​​hole, and at least a portion of the edge of the snap-fit ​​hole is located within the slot, so as to fix the locking member in the snap-fit ​​hole. Through this arrangement, the locking member can be firmly fixed in the snap-fit ​​hole of the mounting base. Due to the tight fit between the slot and the edge of the snap-fit ​​hole, the water pipe is also firmly fixed in the mounting hole, thereby ensuring the stability and reliability of the sprinkler device during use. Therefore, this embedded snap-fit ​​fit not only ensures the stability of the locking member on the mounting base, but also makes the disassembly and assembly process smoother and more reliable.

[0020] Furthermore, the snap-fit ​​hole of the present invention includes a first hole structure and a second hole structure distributed along a first direction. A first end of the first hole structure along the first direction communicates with a first end of the second hole structure along the first direction. The dimension of the first hole structure along the second direction is larger than the dimension of the second hole structure along the second direction. The second direction is perpendicular to the first direction. The locking member includes a body portion, a snap-fit ​​portion, and a connecting portion. The body portion and the snap-fit ​​portion are connected by the connecting portion, and a slot is formed between the body portion and the snap-fit ​​portion. The first hole structure allows the snap-fit ​​portion and the connecting portion to pass through. The connecting portion is located within the second hole structure, and the edge of the second hole structure is located in the slot. This design not only ensures the stability of the locking member on the mounting base but also provides flexibility and tolerance during installation through the ingenious cooperation of the first hole structure, the second hole structure, and the slot. Users can more easily align and insert the locking member during installation without worrying about installation failure due to minor deviations.

[0021] Furthermore, the main body of the present invention is provided with a self-locking structure, which abuts against the second end of the first hole structure along the first direction, and the connecting part abuts against the second end of the second hole structure along the first direction. This double abutment mechanism not only enhances the stability of the locking member on the mounting base, but also restricts the movement of the locking member in the first direction through physical contact, thereby ensuring that the water pipe will not loosen or fall off, ensuring the normal operation of the equipment and the safety of the user.

[0022] Furthermore, the two sides of the connecting portion of the present invention abut against the two inner walls of the second hole structure that are opposite each other along the second direction. This arrangement effectively prevents the connecting portion from shaking or shifting within the second hole structure, thereby further improving the stability of the locking component installation.

[0036] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although the following embodiments are described in conjunction with a dishwasher, the spray device provided by the present invention is equally applicable to other products that need to address the problem of inconvenient disassembly and assembly of water pipes.

[0037] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] As noted in the background section, existing sprinkler systems suffer from inconvenient assembly and disassembly of their water inlet pipes. This invention provides a sprinkler system that utilizes a locking mechanism. This locking mechanism connects to a mounting base via a snap-fit ​​method, securing the water inlet pipe to the mounting base. This achieves convenient assembly and disassembly of the water inlet pipe and ensures a secure connection, providing users with a more convenient and efficient user experience.

[0039] First refer to Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the spray device of the present invention; Figure 2 This is an assembly diagram of the mounting base and locking component of the present invention.

[0040] like Figure 1 and Figure 2 As shown, the present invention provides a spraying device, including a spraying arm (not shown in the figure) and a water inlet pipe 1 connected to the spraying arm. The spraying device also includes a mounting base 2 and a locking member 3 detachably connected to the mounting base 2. The mounting base 2 has a mounting hole 21, and one end of the water inlet pipe 1 is inserted into the mounting hole 21. The mounting base 2 is also provided with a first snap-fit ​​structure, and the locking member 3 is provided with a second snap-fit ​​structure. The first snap-fit ​​structure and the second snap-fit ​​structure are snap-fitted together to fix the locking member 3 to the mounting base 2, thereby fixing the water inlet pipe 1 in the mounting hole 21 by the locking member 3.

[0041] The spraying device provided by this invention mainly consists of a spray arm, a water inlet pipe 1, a mounting base 2, and a locking component 3. These components work together to achieve stable installation of the spray arm and effective water delivery. Specifically, the spray arm, as the core component of the spraying system, is responsible for evenly spraying water to a designated area. The water inlet pipe 1 connects to the water source and the spray arm, guiding the water flow from the water source to the spray arm. One end of the water inlet pipe 1 is inserted into the mounting hole 21 on the mounting base 2, ensuring smooth water flow. The mounting base 2 serves as a support and fixing component for the water inlet pipe 1 and the spray arm. It has a mounting hole 21 for inserting one end of the water inlet pipe 1, ensuring a secure connection between the water inlet pipe 1 and the mounting base 2.

[0042] The locking element 3 is detachably connected to the mounting base 2, enabling convenient installation and removal of the water pipe 1. Users can easily complete the installation or removal process without the need for special tools, greatly saving time and labor costs. The mounting base 2 has a first snap-fit ​​structure, and the locking element 3 has a second snap-fit ​​structure. The two are tightly connected by a snap-fit ​​mechanism, ensuring that the water pipe 1 is securely fixed in the mounting hole 21. This design is not only simple in structure but also provides a firm connection, effectively preventing the water pipe 1 from loosening or falling off during use.

[0043] Furthermore, thanks to the snap-fit ​​structure, users can easily connect or disconnect the locking piece 3 from the mounting base 2 when installing or removing the water pipe 1. This achieves quick connection and disconnection between the water pipe 1 and the mounting base 2, greatly simplifying the assembly and disassembly process. This intuitive and easy-to-understand operation allows even first-time users to quickly get started. The convenient assembly and disassembly process not only improves equipment maintenance efficiency but also reduces user dissatisfaction caused by difficulties in assembly and disassembly. At the same time, the robust connection method ensures the stability and safety of the equipment during use.

[0044] Preferably, such as Figure 3 , Figure 4 and Figure 6As shown, the mounting base 2 is also provided with a snap-fit ​​hole 22. At least a portion of the edge of the snap-fit ​​hole 22 forms a first snap-fit ​​structure. The second snap-fit ​​structure is a slot 31 provided on the locking member 3. The locking member 3 is installed in the snap-fit ​​hole 22, and at least a portion of the edge of the snap-fit ​​hole 22 is located in the slot 31, so as to fix the locking member 3 in the snap-fit ​​hole 22.

[0045] When the locking member 3 is installed into the snap-fit ​​hole 22, at least a portion of the edge of the snap-fit ​​hole 22 will naturally embed into the slot 31 of the locking member 3. This embedded snap-fit ​​not only ensures the stability of the locking member 3 on the mounting base 2, but also makes the assembly and disassembly process smoother and more reliable. Thus, through the above-mentioned snap-fit, the locking member 3 is firmly fixed in the snap-fit ​​hole 22 of the mounting base 2. Due to the tight fit between the slot 31 and the edge of the snap-fit ​​hole 22, the water pipe 1 is also firmly fixed in the mounting hole 21, thereby ensuring the stability and reliability of the sprinkler device during use.

[0046] Preferably, such as Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the snap-fit ​​hole 22 includes a first hole structure 221 and a second hole structure 222 distributed along a first direction. The first end of the first hole structure 221 along the first direction is connected to the first end of the second hole structure 222 along the first direction. The size of the first hole structure 221 along the second direction is larger than the size of the second hole structure 222 along the second direction. The second direction is perpendicular to the first direction. The locking member 3 includes a body part 32, a snap-fit ​​part 33 and a connecting part 34. The body part 32 and the snap-fit ​​part 33 are connected by the connecting part 34. A groove 31 is formed between the body part 32 and the snap-fit ​​part 33. The first hole structure 221 allows the snap-fit ​​part 33 and the connecting part 34 to pass through. The connecting part 34 is located inside the second hole structure 222. The edge of the second hole structure 222 is located in the groove 31.

[0047] In this invention, the snap-fit ​​hole 22 is designed to include two first hole structures 221 and second hole structures 222 distributed along a first direction. The first ends of these two parts are connected in the first direction, but their dimensions differ in the second direction (perpendicular to the first direction). The first hole structure 221 is larger than the second hole structure 222 in the second direction. This design allows for easier and more gradual positioning and stabilization of the locking member 3 during insertion into the first hole structure 221. The locking member 3 consists of three parts: a body part 32, a snap-fit ​​part 33, and a connecting part 34. These three parts are tightly connected by the connecting part 34. A slot 31 is formed between the body part 32 and the snap-fit ​​part 33. Furthermore, in this invention, the shape and size of the slot 31 in the locking member 3 match the second hole structure 222 and its edges of the snap-fit ​​hole 22, thereby improving the fixing effect on the locking member 3.

[0048] For example, during installation, the locking member 3's snap-fit ​​portion 33 and connecting portion 34 first pass through the first hole structure 221. Since the first hole structure 221 is relatively large in the second direction, this process is relatively easy. Subsequently, the connecting portion 34 enters the second hole structure 222. Because the second hole structure 222 is smaller, the connecting portion 34 is confined within it and cannot easily retract. At this point, the edge of the second hole structure 222 naturally embeds into the slot 31, forming a secure snap-fit. Therefore, this design not only ensures the stability of the locking member 3 on the mounting base 2, but also provides flexibility and tolerance during installation through the ingenious cooperation of the first hole structure 221, the second hole structure 222, and the slot 31. Users can more easily align and insert the locking member 3 during installation without worrying about installation failure due to minor deviations.

[0049] Preferably, such as Figure 6 As shown, a self-locking structure 35 is provided on the main body 32. The self-locking structure 35 abuts against the second end of the first hole structure 221 along the first direction, and the connecting part 34 abuts against the second end of the second hole structure 222 along the first direction.

[0050] In this invention, a self-locking structure 35 is provided on the main body 32. The main function of this structure is to provide additional locking force after the locking member 3 is installed in place, ensuring that the locking member 3 will not accidentally loosen or fall off due to external factors (such as vibration, water pressure, etc.). The self-locking structure 35 is designed to abut against the second end of the first hole structure 221 along the first direction, and at the same time, the connecting part 34 also abuts against the second end of the second hole structure 222 along the first direction. This double abutment mechanism not only enhances the stability of the locking member 3 on the mounting base 2, but also restricts the movement of the locking member 3 in the first direction through physical contact. This ensures that the water pipe 1 will not loosen or fall off, guaranteeing the normal operation of the equipment and the safety of the user.

[0051] It should be noted that the present invention does not limit the structural form of the self-locking structure 35. For example, the self-locking structure 35 can be set as a self-locking rib or a self-locking block, etc.

[0052] Preferably, the two sides of the connecting portion 34 abut against the two inner walls of the second hole structure 222 that are opposite each other along the second direction.

[0053] The two sides of the connecting part 34 are designed to abut tightly against the two inner walls of the second hole structure 222 along the second direction (i.e., perpendicular to the first direction). This design effectively prevents the connecting part 34 from shaking or shifting within the second hole structure 222, enhancing its stability and positioning accuracy. Specifically, because both sides of the connecting part 34 abut against the inner walls, it effectively prevents shaking or shifting within the second hole structure 222. This stable connection not only improves the overall structural strength of the spray device but also ensures the secure fixing of the water pipe 1 in the mounting hole 21, reducing the risk of loosening due to vibration or water pressure fluctuations. When installing the locking part 3, the user can also determine whether the locking part 3 is correctly installed by observing the contact between the connecting part 34 and the inner wall. This intuitive positioning method simplifies the installation process and reduces installation difficulty.

[0054] Preferably, such as Figures 3 to 5 As shown, the second hole structure 222 is a strip-shaped hole extending along the first direction.

[0055] The second hole structure 222 is designed as a strip-shaped hole extending along the first direction. This design allows the connecting part 34 a certain degree of freedom during insertion, making it easy for the user to adjust the position of the locking member 3 to ensure its correct installation. At the same time, the strip-shaped hole also provides additional space to accommodate the slight displacement that the connecting part 34 may undergo when subjected to external forces, thereby enhancing the stability of the locking member 3.

[0056] Preferably, such as Figure 6 and Figure 7 As shown, the main body 32 includes a plate-shaped body 321 and a handle 322 disposed on the plate-shaped body 321. The handle 322 is located on the side of the plate-shaped body 321 away from the latching part 33. The latching part 33 is connected to the plate-shaped body 321 through the connecting part 34 and forms a slot 31 between the latching part 33 and the plate-shaped body 321.

[0057] The main body 32 is designed to include a plate-shaped body 321 and a handle 322 disposed on the plate-shaped body 321. This design not only makes the main body 32 more robust and durable, but also improves the ease of operation for the user through the addition of the handle 322. The handle 322 is located on the side of the plate-shaped body 321 away from the locking part 33. This layout allows the user to easily apply force to the locking member 3 when operating the handle 322 without worrying about causing unnecessary interference to the locking part 33 or the connecting part 34. The locking part 33 is tightly connected to the plate-shaped body 321 through the connecting part 34, forming a groove 31 between them. This groove 31 is the key part of the locking engagement between the locking member 3 and the mounting base 2. It ensures that the locking member 3 can be firmly fixed on the mounting base 2, further ensuring the secure fixation of the water pipe 1 in the mounting hole 21.

[0058] Preferably, such as Figure 6 and Figure 7 As shown, the connecting part 34 is arranged perpendicularly to the plate-shaped body 321, and the snap-fit ​​part 33 is arranged parallel to the plate-shaped body 321.

[0059] The connecting part 34 is designed to be perpendicular to the plate-shaped body 321. This layout not only enhances the stability of the connecting part 34, but also allows the locking member 3 to pass through the first hole structure 221 and enter the second hole structure 222 more smoothly during installation. The snap-fit ​​part 33 is arranged parallel to the plate-shaped body 321. This design makes the shape of the slot 31 more regular, which facilitates snap-fit ​​with the edge of the second hole structure 222. At the same time, it also ensures that the locking member 3 can be firmly fixed on the mounting base 2 after installation.

[0060] Preferably, such as Figure 6 and Figure 7 As shown, the snap-fit ​​part 33 has a block-shaped structure or a plate-shaped structure.

[0061] The snap-fit ​​part 33 can be a block structure or a plate structure. The block structure provides a larger contact area and stronger structural strength, while the plate structure is thinner and easier to install and disassemble.

[0062] Preferably, such as Figure 6 and Figure 7 As shown, the connecting part 34 is a columnar structure or a plate-like structure.

[0063] The connecting part 34 can also be either a columnar structure or a plate structure. The columnar structure provides better support in the vertical direction, while the plate structure is easier to process and install.

[0064] It should be noted that the specific shapes of the snap-fit ​​part 33 and the connecting part 34 can be set according to the actual working conditions, as long as they can facilitate the installation of the locking part 3 and provide a good fixing effect for the water pipe 1. The present invention does not specifically limit the shapes of the snap-fit ​​part 33 and the connecting part 34.

[0065] Preferably, such as Figure 6 and Figure 7 As shown, the locking member 3 is provided with a limiting part 36, and the water pipe 1 is provided with a limiting structure. The limiting part 36 can cooperate with the limiting structure to fix the water pipe 1 in the mounting hole 21.

[0066] By providing a limiting part 36 on the locking member 3 and a limiting structure on the water pipe 1, the limiting structure and the limiting part 36 can fit tightly together after the water pipe 1 is inserted into the mounting hole 21. This not only limits the range of movement of the water pipe 1 in the mounting hole 21, but also provides additional fixing force through physical contact, firmly fixing the water pipe 1 in the mounting hole 21, and maintaining stability even in the face of high-intensity spraying operations.

[0067] It should be noted that the limiting part 36 in this invention is a baffle plate disposed on the edge of the plate-shaped body 321. When the locking member 3 is installed in place, the baffle plate can cooperate with the limiting structure on the water inlet pipe 1 to prevent the water inlet pipe 1 from coming out of the installation hole 21. Furthermore, the limiting part 36 can also be a block, a rib, etc. This invention does not limit the specific structural form of the limiting part 36, as long as it can cooperate with the limiting structure on the water inlet pipe 1 to limit the water inlet pipe 1.

[0068] Preferably, such as Figure 3 , Figure 4 and Figure 8 As shown, an annular limiting platform 211 is provided on the inner wall of the mounting hole 21 along the circumferential direction. The limiting structure is an annular limiting plate 11 provided on the water pipe 1. The annular limiting platform 211 abuts against one side of the annular limiting plate 11, and the limiting part 36 abuts against the other side of the annular limiting plate 11.

[0069] In this invention, an annular limiting platform 211 is provided circumferentially on the inner wall of the mounting hole 21. This limiting platform provides a stable support point for the water pipe 1 and restricts its movement within the mounting hole 21. The limiting structure is an annular limiting plate 11 mounted on the water pipe 1, which matches the annular limiting platform 211. When the water pipe 1 is inserted into the mounting hole 21, the annular limiting plate 11 naturally contacts the annular limiting platform 211, providing additional fixing force through physical contact. After the water pipe 1 and the locking member 3 are installed in place, on the one hand, the annular limiting platform 211 abuts against one side of the annular limiting plate 11, restricting the downward movement of the water pipe 1 within the mounting hole 21; on the other hand, the limiting part 36 on the locking member 3 abuts against the other side of the annular limiting plate 11, further enhancing the fixing effect. This double abutment mechanism makes the position of the water pipe 1 in the mounting hole 21 more stable, reducing the risk of loosening due to vibration or water pressure fluctuations.

[0070] It should be noted that the limiting structure can also be a block, a rib, etc., arranged at intervals along the circumference of the water pipe 1. The present invention does not limit the specific structural form of the limiting structure, as long as it can cooperate with the annular limiting platform 211 and the limiting part 36 to fix the water pipe 1.

[0071] In addition, the present invention also provides a dishwasher including the spray device described above.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
