Abstract
Description
Technical Field
[0001] This utility model belongs to the field of washing machine technology, specifically relating to a nozzle assembly for a washing machine. Background Technology
[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. It is classified into two categories based on its rated washing capacity: household and commercial. The washing machine nozzle is a key component installed inside the washing machine, commonly referred to as the washing spray head or shower nozzle. Its main function is to rinse and wash clothes by spraying water.
[0003] Patent CN212983363U discloses "a water-saving spray head for a washing machine, including a connecting pipe, a water pipe, a main body, and spray holes. The spray holes are evenly arranged at the bottom of the main body, and an adjustment structure is provided inside the main body. A toggle block is fixed at the bottom of the slider, and a pre-drilled hole is evenly distributed inside the baffle. This utility model, by providing an adjustment structure, allows for the adjustment of the water output by holding the toggle block and rotating the baffle through the slider in the slide groove when adding water to the washing machine. This causes the baffle to block the spray holes, making the water output more convenient and effectively improving the practicality and water conservation of the spray head."
[0004] Although the water output of the nozzle can be adjusted using the existing technology, it cannot adjust the rinsing range of the nozzle. Because it has multiple nozzles, the rinsing water flow is relatively dispersed, making it difficult to concentrate the rinsing water flow into a single direct jet, resulting in poor rinsing effect on heavy clothes. In this regard, this application proposes a nozzle assembly for a washing machine. Utility Model Content
[0005] The purpose of this invention is to provide a nozzle assembly for a washing machine in order to solve the above-mentioned problems.
[0006] This utility model achieves the above objectives through the following technical solutions:
[0007] A nozzle assembly for a washing machine includes a nozzle body and a water flow adjustment mechanism installed on the outside of the nozzle body. The nozzle body has a spray hole at its bottom. The water flow adjustment mechanism includes a miniature electric push rod rotatably disposed on the outside of the nozzle body, a movable rod fixedly disposed at the bottom end of the miniature electric push rod, and a conical block disposed at the bottom end of the movable rod and located directly below the spray hole. A first triangular plate is fixedly disposed on the outer wall of the bottom end of the nozzle body, and a second triangular plate is fixedly disposed on the outer wall of the movable rod. The inclined surfaces of the first and second triangular plates abut against each other.
[0008] As a further optimization of this utility model, a threaded groove is provided inside the top of the nozzle body, a fixing ring is fixedly provided on the outer wall of the nozzle body, and the miniature electric push rod is rotatably connected to the bottom edge of the fixing ring.
[0009] As a further optimization of this utility model, a first connecting rod is fixedly provided on the outer wall of the bottom end of the movable rod, and the conical block is fixedly connected to one end of the first connecting rod.
[0010] As a further optimization of this utility model, a second connecting rod is fixedly provided on the outer wall of the top end of the movable rod, and an iron half-ring is fixedly provided at one end of the second connecting rod.
[0011] As a further optimization of this utility model, a cleaning component is fixedly provided on the inner side of the iron semi-ring, and the cleaning component is fitted against the outer wall of the nozzle body.
[0012] As a further optimization of this utility model, a groove is provided on the outer wall of the nozzle body, and a magnet block that is magnetically attracted to an iron semi-ring is fixed in the groove of the nozzle body, and one side of the cleaning component abuts against the outer wall of the magnet block.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The extension and retraction of the miniature electric push rod drives the cone block to move up and down. When the cone block moves up, it gets closer to the nozzle and disperses the water flow discharged from the nozzle, thereby expanding the rinsing range of the water flow and making it easier to wash thin clothes. As the cone block and other components continue to move down, with the guidance of the first and second triangular plates, the cone block can be pushed open from below the nozzle, so that the nozzle can spray directly onto thick clothes. Overall, by adjusting the rinsing range of the nozzle, more precise cleaning can be performed on different types and materials of clothes, improving the cleaning effect.
[0015] 2. The magnetic attraction between the magnet and the iron half-ring limits the movement of components such as the movable rod and the cone block, facilitating the vertical movement of these components. After the movable rod and other components move up and down, the cleaning component partially cleans the surface of the magnet and the nozzle body, improving the cleanliness of the magnet surface and thus not affecting the magnetic attraction between the magnet and the iron half-ring.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0021] Example
[0022] like Figure 1-3 As shown, the nozzle assembly for a washing machine includes a nozzle body 1 and a water flow adjustment mechanism. The water flow adjustment mechanism is installed on the outside of the nozzle body 1 and can adjust the rinsing range of the water flow sprayed from the bottom of the nozzle body 1.
[0023] like Figure 1-2 As shown, the nozzle body 1 has a spray hole 11 at the bottom and a threaded groove 12 at the top. A fixing ring 13 is fixed on the outer wall of the nozzle body 1. The nozzle body 1 is installed vertically inside the washing machine so that the spray hole 11 of the nozzle body 1 faces downward. The nozzle body 1 can spray water through the spray hole 11. An external water pipe can be threadedly connected to the threaded groove 12 of the nozzle body 1 for easy disassembly and assembly of the nozzle.
[0024] like Figure 1-2 As shown, the water flow adjustment mechanism includes a miniature electric push rod 2 rotatably mounted on the outside of the nozzle body 1, a movable rod 21 fixedly mounted on the bottom end of the miniature electric push rod 2, and a conical block 23 located at the bottom end of the movable rod 21 and directly below the nozzle hole 11. A threaded groove 12 is provided inside the top of the nozzle body 1, and a fixing ring 13 is fixedly mounted on the outer wall of the nozzle body 1. The miniature electric push rod 2 is rotatably connected to the bottom edge of the fixing ring 13. A first connecting rod 22 is fixedly mounted on the outer wall of the bottom end of the movable rod 21. The conical block 23 is fixedly connected to one end of the first connecting rod 22. The fixing ring 13 can connect the nozzle body 1 and the miniature electric push rod 2, and the first connecting rod 22 can connect the movable rod 21 and the conical block 23.
[0025] The extension and retraction of the micro electric push rod 2 can drive the cone block 23 to move up and down. When the cone block 23 moves up, it can get closer to the nozzle 11 and disperse the water flow discharged from the nozzle 11. When the cone block 23 moves down, it will move away from the nozzle 11, thereby reducing the rinsing range of the water flow. This can adjust the rinsing range of the water flow sprayed from the nozzle. When the rinsing range of the nozzle increases, the rinsing force on the clothes will decrease, making it easier to wash thin clothes.
[0026] like Figure 1-2 As shown, a first triangular plate 24 is fixedly provided on the outer wall of the bottom end of the nozzle body 1, and a second triangular plate 25 is fixedly provided on the outer wall of the movable rod 21. The inclined surfaces of the first triangular plate 24 and the second triangular plate 25 are engaged and abutted. When the cone block 23 continues to move downward, it will drive the second triangular plate 25 to move downward. At this time, under the guidance of the inclined surface between the first triangular plate 24 and the second triangular plate 25, the miniature electric push rod 2, the movable rod 21 and the cone block 23 connected to the bottom of the fixed ring 13 will be pushed to the side away from the nozzle body 1, so that the movable rod 21 and other components are tilted. At this time, the cone block 23 will be pushed open from below the nozzle 11, so that the nozzle 11 can directly spray water onto the clothes. Since the force of the single-hole direct spray of the nozzle 11 is relatively large, the water flow can penetrate into the thick clothes, making it easier to wash away the thick foreign objects.
[0027] like Figure 1 and Figure 3 As shown, a second connecting rod 3 is fixedly provided on the outer wall of the top of the movable rod 21. An iron half-ring 31 is fixedly provided on one end of the second connecting rod 3. A cleaning component 32 is fixedly provided on the inner side of the iron half-ring 31. The cleaning component 32 abuts against the outer wall of the nozzle body 1. The second connecting rod 3 can connect the movable rod 21 and the iron half-ring 31. The iron half-ring 31 and the cleaning component 32 abut against the outer side of the nozzle body 1, which can limit the movement of the movable rod 21 and the conical block 23 and other components. The cleaning component 32 can be a cleaning sponge or other object with cleaning effect.
[0028] like Figure 1 and Figure 3 As shown, a groove 14 is provided on the outer wall of the nozzle body 1. A magnet block 15 that is magnetically attracted to the iron half-ring 31 is fixed in the groove 14 of the nozzle body 1. One side of the cleaning component 32 is engaged with the outer wall of the magnet block 15. The nozzle body 1 can hide and fix the magnet block 15 through the groove 14. Through the magnetic attraction between the magnet block 15 and the iron half-ring 31, the movable rod 21 and the conical block 23 and other components can be limited, so that the conical block 23 and other components can move vertically.
[0029] After the miniature electric push rod 2 extends and retracts, it drives the movable rod 21 and cleaning component 32 to move up and down. The moving cleaning component 32 will partially clean the surface of the magnet block 15 and the nozzle body 1, improving the cleanliness of the surface of the magnet block 15 and the nozzle body 1. This prevents foreign objects such as laundry detergent from adhering to the surface of the magnet block 15 and affecting the magnetic attraction between the magnet block 15 and the iron half ring 31.
[0030] It should be noted that, when using the nozzle assembly for the washing machine, firstly, the external water pipe can be threadedly connected to the threaded groove 12 of the nozzle body 1, and then the nozzle body 1 is vertically installed inside the washing machine so that the spray hole 11 of the nozzle body 1 faces downward. The nozzle body 1 can spray water through the spray hole 11 to wash the clothes inside the washing machine.
[0031] Furthermore, controlling the extension and retraction of the micro electric push rod 2 can drive the cone block 23 to move up and down. After the cone block 23 moves up, it can approach the nozzle 11 and disperse the water flow discharged from the nozzle 11. After the cone block 23 moves down, it will move away from the nozzle 11, thereby reducing the rinsing range of the water flow. This allows the rinsing range of the water flow sprayed from the nozzle to be adjusted. After the rinsing range of the nozzle increases, the rinsing force on the clothes will decrease, making it easier to wash thin clothes. At this time, under the magnetic attraction of the magnet block 15 and the iron half ring 31, the vertical movement of the cone block 23 can be guaranteed, thereby limiting the position of the cone block 23 and other components.
[0032] As the cone block 23 continues to move downward, it will drive the second triangular plate 25 to move downward. At the same time, under the guidance of the inclined surface between the first triangular plate 24 and the second triangular plate 25, the miniature electric push rod 2, movable rod 21, iron half ring 31 and cone block 23 connected to the bottom of the fixed ring 13 will be pushed to the side away from the nozzle body 1, so that the iron half ring 31 and the cleaning part 32 can be separated from the outside of the nozzle body 1. At this time, the movable rod 21 and other components will tilt, so that the cone block 23 will be pushed open from below the nozzle 11, making it easier for the nozzle 11 to spray directly onto the clothes. Because the spray force of the nozzle 11 is relatively large, the water flow can penetrate into the thick clothes, making it easier to wash away the thick foreign objects.
[0033] Overall, by adjusting the rinsing range of the nozzle, it is possible to perform more precise cleaning on different types and materials of clothing, thereby improving the cleaning effect.
[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
