Description

Technical Field

[0001] This utility model relates to the technical field of dishwashers, and in particular to a spherical pressurized spray device. Background Technology

[0002] Dishwashers are kitchen helpers for homes and businesses, automatically washing dishes, chopsticks, plates, dishes, knives, forks, and other tableware to help people reduce their housework burden.

[0003] As dishwasher technology matures, modular dishwashers have emerged. The increasingly competitive market requires continuous innovation to attract consumers, and innovations in everything from the exterior to the internal dish rack and spray arms are what customers perceive most directly. Various spray arm designs are constantly being developed, but most remain based on the most efficient 'straight-line' and 'cross-shaped' spray arms; other shapes are mostly auxiliary washing spray arms.

[0004] In existing dishwashers, the spray arm and nozzle are mostly designed as a single unit, making it difficult to disassemble and replace the nozzle if it is damaged.

[0005] In summary, there is a need for a spherical pressurized spray device that is easy to assemble and disassemble and allows for quick nozzle replacement. Utility Model Content

[0006] This invention aims to overcome the shortcomings of existing technologies where the spray arm and nozzle are mostly designed as a single unit, making it difficult to disassemble and replace the nozzle after damage. It provides a spherical pressurized spray device that is easy to assemble and disassemble and allows for quick nozzle replacement.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A spherical pressurized spray device includes a water connector and a nozzle body. The nozzle body includes a water guide pipe and a spray head. Both ends of the water guide pipe are provided with connecting caps. The ends of the water guide pipe are mounted on the bottom surface of the connecting caps and the two are connected. The water connector is provided with a first connecting nozzle. The cap opening of one of the connecting caps matches the first connecting nozzle and the two are threaded together. One end of the spray head is provided with a second connecting nozzle. The cap opening of the other connecting cap matches the second connecting nozzle and the two are threaded together.

[0009] When installing the spray head, align the second connector of the spray head with the cap on the other connector, and then tighten the second connector to the cap. When installing the spray head body, align the cap of one connector with the first connector, and then tighten the cap to the first connector. The connection method is simple and easy to operate, facilitating installation and disassembly, allowing for quick spray head replacement, reducing the difficulty of later maintenance and repair, and providing good sealing. Water flowing from the first connector can flow to the spray head through the water guide pipe.

[0010] Preferably, the spray head consists of a symmetrical left and right half-shell, which are fixed together by ultrasonic welding. This design is simple in structure and easy to manufacture.

[0011] Preferably, the bottom surface of the connecting cap has a connecting cap through hole, and the end of the water guide pipe passes through the connecting cap through hole and is placed inside the connecting cap. A sealing gasket is also provided inside the connecting cap, and the sealing gasket is installed between the end of the water guide pipe and the connecting cap through hole. During installation, the end of the water guide pipe is passed through the connecting cap through hole and placed inside the connecting cap. Then, the sealing gasket is installed between the end of the water guide pipe and the connecting cap through hole, thus wrapping around the end of the water guide pipe. The sealing gasket not only provides a seal but also wraps around the end of the water guide pipe and provides a limiting and fixing function.

[0012] Preferably, the end of the water guide pipe is spherical. This spherical design serves two purposes: firstly, it pressurizes the water flow, increasing cleaning power; secondly, the spray head can rotate omnidirectionally using the spherical end of the water guide pipe, changing the spray direction and adjusting the cleaning angle.

[0013] Preferably, the surface of the spray head is provided with several spray holes, which are located at the other end of the spray head. An adjusting cover is provided on the outer side of the spray head, and is rotatably connected to the other end of the spray head. The adjusting cover has adjusting holes that match the spray holes. Users can rotate the adjusting cover on the outer side of the spray head according to actual needs, so that some adjusting holes and some spray holes are staggered or overlapped, thereby controlling the opening or closing of spray holes at different positions. The operation is simple and convenient. Water is pressurized once at the water guide tube of the double-ball head, and then pressurized again at the spray holes, resulting in better cleaning effects for deep cups and other tableware.

[0014] Preferably, the outer surface of the spray head is provided with a ball-ring buckle movable groove. A ball-ring buckle is movably connected to the opening of the ball-ring buckle movable groove. One side of the ball-ring buckle and the bottom surface of the ball-ring buckle movable groove are connected by a spring. The adjusting cover is provided with several ball-ring buckle slots. The ball-ring buckle slots are arranged in an arc shape on the inner wall of the adjusting cover, and the center of the arc coincides with the rotation center of the adjusting cover. The ball-ring buckle is located on the rotation trajectory of the ball-ring buckle slot, and the other side of the ball-ring buckle slot and the ball-ring buckle are engaged and matched. Several ball-ring buckle slots correspond to several different spray hole adjustment positions. When the user rotates the adjusting cover to a certain position, the ball-ring buckle slot on the adjusting cover also moves to the ball-ring buckle on the spray head. At this time, the ball-ring buckle at the opening of the ball-ring buckle movable groove will automatically engage with the ball-ring buckle slot under the elastic force of the second spring, thereby completing the relative fixation between the spray head and the adjusting cover. The structure is simple, the operation is convenient, and the fixing effect is good.

[0015] The beneficial effects of this utility model are: the nozzle is easy to disassemble and assemble, and the nozzle can be quickly replaced, reducing the difficulty of later maintenance and repair; it can pressurize the water circuit and improve the cleaning power; the spray direction can be changed and the cleaning angle can be adjusted; the nozzles at different positions can be controlled to open or close, which is simple to operate and convenient to control; and it improves the fixing effect between the spray head and the adjusting cover.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , Figure 2 and Figure 3 In the embodiments described, a spherical pressurized spray device includes a water connector 1 and a nozzle body 2. The nozzle body 2 includes a water guide pipe 3 and a spray head 4. Both ends of the water guide pipe 3 are provided with connecting caps 5. The ends of the water guide pipe 3 are mounted on the bottom surface of the connecting caps 5 and the two are connected. The water connector 1 is provided with a connecting nozzle 6. The cap opening of one of the connecting caps 5 matches the connecting nozzle 6 and the two are threaded together. One end of the spray head 4 is provided with a connecting nozzle 7. The cap opening of the other connecting cap 5 matches the connecting nozzle 7 and the two are threaded together.

[0024] like Figure 4 As shown, the water nozzle 4 is composed of a left half shell 8 and a right half shell 9 that are symmetrical to each other. The left half shell 8 and the right half shell 9 are fixed together by ultrasonic welding.

[0025] like Figure 2 As shown, the bottom surface of the connecting cap 5 is provided with a connecting cap through hole 10. The end of the water guide pipe 3 passes through the connecting cap through hole 10 and is placed inside the connecting cap 5. The inner side of the connecting cap 5 is also provided with a sealing gasket 11, which is installed between the end of the water guide pipe 3 and the connecting cap through hole 10.

[0026] like Figure 2 As shown, the end of the water pipe 3 is spherical.

[0027] like Figure 2 As shown, the surface of the spray head 4 is provided with a number of spray holes 12. The spray holes 12 are located at the other end of the spray head 4. An adjustment cover 13 is provided on the outside of the spray head 4. The adjustment cover 13 is installed on the other end of the spray head 4 and is rotatably connected to it. The adjustment cover 13 is provided with adjustment holes 14 that match the spray holes 12.

[0028] like Figure 2 As shown, a ball buckle movable groove 15 is provided on the outer surface of the spray head 4. A ball buckle 16 is movably connected to the opening of the ball buckle movable groove 15. One side of the ball buckle 16 and the bottom surface of the ball buckle movable groove 15 are connected by a spring 17. A number of ball buckle slots 18 are provided on the adjusting cover 13. The ball buckle slots 18 are arranged in an arc shape on the inner wall of the adjusting cover 13, and the center of the arc coincides with the rotation center of the adjusting cover 13. The ball buckle 16 is located on the rotation trajectory of the ball buckle slot 18, and the other side of the ball buckle slot 18 and the ball buckle 16 are engaged and matched.

[0029] When installing the nozzle body 2, pass the end of the water guide pipe 3 through the connecting cap through hole 10 and place it inside the connecting cap 5. Then, install the sealing gasket 11 between the end of the water guide pipe 3 and the connecting cap through hole 10, and wrap the end of the water guide pipe 3. Next, align the second connecting nozzle 7 of the spray head 4 with the cap opening on the other connecting cap 5, and then tighten the second connecting nozzle 7 to the cap opening. Finally, align the cap opening of one of the connecting caps 5 with the first connecting nozzle 6, and then tighten the cap opening to the first connecting nozzle 6 to complete the installation. The end of the water guide pipe 3 adopts a ball-shaped design, which can pressurize the water path and improve the cleaning power. On the other hand, the spray head 4 can rotate omnidirectionally with the ball end of the water guide pipe 3 to change the spray direction and adjust the cleaning angle.

[0030] The water is pressurized once at point 3 of the double-ball head water guide pipe, and then pressurized again at point 12 of the spray nozzle, which makes it more effective for cleaning tableware such as deep cups.

[0031] Users can rotate the adjustment cover 13 on the outside of the spray head 4 according to actual needs, so that some adjustment holes 14 and some spray holes 12 are staggered or overlapped, thereby controlling the opening or closing of spray holes 12 at different positions. Several ball buckle slots 18 correspond to several different spray hole adjustment positions. When the user rotates the adjustment cover 13 to a certain position, the ball buckle slot 18 on the adjustment cover 13 also moves to the ball buckle 16 on the spray head 4. At this time, the ball buckle 16 at the opening of the ball buckle movable groove 15 will automatically lock into the ball buckle slot 18 under the elastic force of the spring 17, completing the fixation between the spray head 4 and the adjustment cover 13.

[0032] like Figure 5 As shown, the surface of the spray head 4 is provided with 4 inner ring spray holes and 8 outer ring spray holes. The outer ring spray holes are located outside the inner ring spray holes and the diameter of the outer ring spray holes is larger than that of the inner ring spray holes. The 4 inner ring spray holes and 8 outer ring spray holes are evenly distributed in a ring on the outer side of the rotation center of the adjusting cover 13. The adjusting cover 13 is provided with 4 inner ring adjusting holes and 8 outer ring adjusting holes that correspond one-to-one.

[0033] When the adjusting cover 13 is rotated 45°, the spray head 4 and the adjusting cover 13 engage once. At this time, the outer ring spray hole opens, while the inner ring spray hole is offset from the inner ring adjusting hole, and the inner ring spray hole closes. When the adjusting cover 13 is rotated 90°, the spray head 4 and the adjusting cover 13 engage a second time. At this time, the outer ring spray hole opens, and the inner ring spray hole coincides with the inner ring adjusting hole, and the inner ring spray hole also opens.
