Description

Technical Field

[0001] This utility model belongs to the field of cleaning machine technology, specifically relating to a quick-connect rotary adjustable nozzle. Background Technology

[0002] Spray guns are frequently used in industrial cleaning, garden maintenance, and other fields. Quick-connect rotary adjustable nozzles are widely used due to their advantages such as convenient spray flow adjustment and easy connection to spray guns.

[0003] Currently, the most common quick-connect adjustable nozzles on the market are the duckbill rotary quick-connect adjustable nozzle and the gear-shifting rotary quick-connect adjustable nozzle. The duckbill rotary adjustable nozzle has a symmetrical pressure plate inside. By rotating the nozzle shell, the distance between the tops of the pressure plates is adjusted, thus changing the spray flow rate. The gear-shifting rotary adjustable nozzle has a rotating wheel at the nozzle outlet. Multiple nozzles of different sizes are evenly distributed on the wheel. Adjustment is achieved by rotating the wheel to align the corresponding nozzle with the water channel, thereby changing the spray flow rate or angle. Because the different nozzle sizes are arranged on the rotating wheel, the overall size of this nozzle is relatively large, and the axes of the nozzles are parallel to but not coincident with the axis of the quick-connect plug, resulting in higher water resistance.

[0004] Both of the aforementioned quick-connect adjustable nozzles are adjusted by rotation. However, the axis of the adjustment knob is parallel to the axis of the quick-connect direction of the spray gun nozzle, causing slippage at the quick-connect connection point during rotation adjustment (slippage between the nozzle and the spray gun body), resulting in a poor user experience. Adding a limiting mechanism at the nozzle-gun body connection could solve the slippage problem, but it would complicate the structure and prevent compatibility with common quick-connect couplings on the market. Summary of the Invention

[0005] This invention addresses the shortcoming of existing quick-connect adjustable nozzles, where the axis of adjustment rotation is parallel to the axis of the quick-connect direction, causing the nozzle to slip easily during rotation adjustment. It provides a quick-connect rotary adjustable nozzle that changes the water outlet adjustment structure to prevent the nozzle from slipping during adjustment.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a quick-connect rotary adjustable nozzle, wherein the quick-connect rotary adjustable nozzle comprises:

[0007] Quick plug;

[0008] The outer casing is fixed to the quick-connect plug and has a water outlet hole.

[0009] The adjustment component is oscillatingly housed within the casing;

[0010] The control component, which is linked to the adjustment component, has a control part located outside the housing;

[0011] The regulating component has multiple water flow channels that can communicate with the water outlet of the shell, and at least some of the water flow channels have different water outlets.

[0012] In this device, all water flow channels of the quick-connect plug are straight, the water outlet of the housing is coaxial with the water flow channels of the quick-connect plug, and the rotation axis of the control component is perpendicular to the axis of the water outlet of the housing.

[0013] This utility model discloses a quick-connect rotary adjustable nozzle, in which the rotation axis of the control component is perpendicular to the axis of the water outlet of the outer shell. When operating the control component, the quick-connect plug will not rotate; it features a quick-connect plug for rapid insertion; the entire nozzle emits water in a straight line (without bends). Different outlets may be due to variations in the diameter and / or number and / or shape of the water outlet holes.

[0014] As an improvement, the regulating assembly includes an regulating member and multiple nozzles, each nozzle being fixedly connected to the regulating member, and the aforementioned water outlet is formed on the nozzle.

[0015] As an improvement, the adjusting component is spherical; multiple mounting slots of the same size are opened on the adjusting component, and the nozzle is installed in the mounting slot, with the outer end face of each mounting slot being flat.

[0016] As an improvement, the outer shell is fitted over the quick plug. The outer shell is cylindrical and has an end wall with the aforementioned water outlet hole. A first sealing ring is provided between the adjusting component and the end wall of the outer shell, and a second sealing ring is provided between the adjusting component and the end face of the quick plug. The first sealing ring seals the adjusting component and the outer shell, and the second sealing ring seals the adjusting component, the outer shell, and the quick plug.

[0017] As an improvement, the housing is threadedly connected to the quick-connect plug; the quick-connect plug includes a quick-connect portion and a threaded connection portion, the radial dimension of which is larger than that of the quick-connect portion.

[0018] As an improvement, a linkage groove is opened on the adjustment component, and the control component forms a linkage block that cooperates with the linkage groove.

[0019] As an improvement, the outer shell extends radially to form a control mounting part. The control component includes a control member and a third sealing ring that seals the control member and the control mounting part. The inner and outer ends of the control member respectively form the aforementioned linkage block and control part. The control member forms a sealing ring mounting part, and a sealing ring mounting groove is provided on the sealing ring mounting part.

[0020] As an improvement, the adjustment component swings relative to the housing, and the swing angle of the adjustment component is less than 180°.

[0021] As an improvement, a swing angle limiting structure and a positioning structure are formed between the control component and the control mounting part. The swing angle limiting structure includes a limiting groove opened on the control mounting part and a limiting part formed on the control component. The positioning structure includes a positioning groove opened on the control mounting part and a positioning rib formed on the control component. The positioning groove is located on the circumferential bottom wall of the limiting groove.

[0022] As an improvement, all water flow channels of the regulating component are straight.

[0023] As an improvement, the water outlet includes several water outlet holes, and the water outlets are different in that the diameter and / or number and / or shape of the water outlet holes are different.

[0024] The beneficial effects of this utility model's quick-connect rotary adjustable nozzle are: the rotation axis of its control component is perpendicular to the axis of the water outlet hole of the outer shell, so the quick-connect plug will not rotate when the control component is operated; the quick-connect plug enables rapid insertion.

[0044] This utility model discloses a quick-connect rotary adjustable nozzle, in which the rotation axis of the control component is perpendicular to the axis of the water outlet hole of the outer shell. When operating the control component, the quick-connect plug will not rotate; the quick-connect plug allows for rapid insertion. Different water outlets may have different outlet hole diameters and / or numbers and / or shapes.

[0045] Example 1

[0046] See Figures 1 to 9The quick-connect rotary adjustable nozzle of Embodiment 1 of this utility model includes:

[0047] Quick plug 1;

[0048] The outer casing 2 is fixedly connected to the quick plug 1, and has a water outlet hole 221.

[0049] Adjustment component 3 is oscillatingly disposed within housing 2;

[0050] The control component 4, which is linked to the adjustment component 3, has a control part 412 located outside the housing 2;

[0051] The regulating component 3 has multiple water flow channels that can communicate with the water outlet 221 of the shell, and at least some of the water flow channels have different water outlets.

[0052] In this device, each water flow channel of the quick plug 1 is straight, the water outlet 221 of the housing is coaxial with the water flow channel of the quick plug 1, and the rotation axis of the control component 4 is perpendicular to the axis of the water outlet 221 of the housing.

[0053] In this embodiment, the quick-connect plug 1 includes a quick-connect portion 11 and a threaded connection portion 12, wherein the radial dimension of the threaded connection portion 12 is larger than the radial dimension of the quick-connect portion 11. The quick-connect plug 1 also includes an abutment portion 13, and when the housing 2 abuts against the abutment portion 13 of the quick-connect plug 1, it indicates that the housing 2 and the quick-connect plug 1 have been rotated into place.

[0054] In this embodiment, the outer shell 2 is threadedly connected to the quick-connect plug 1. The outer shell 2 is fitted over the quick-connect plug 1. The quick-connect plug 1 has external threads, and the outer shell 2 has internal threads.

[0055] In this embodiment, the adjustment assembly 3 includes an adjustment member 31 and a plurality of nozzles 32. Each nozzle 32 is fixedly connected to the adjustment member 31, and the aforementioned water outlet is formed on the nozzle 32. It is preferable that the nozzles 32 and the adjustment member 31 are threadedly connected, which not only ensures a firm connection but also makes it easy to replace the nozzles 32.

[0056] In this embodiment, the adjusting member 31 is spherical; multiple mounting slots 312 of the same size are formed on the adjusting member 31, and the nozzle 32 is installed in the mounting slots 312. The mounting slots 312 are T-shaped, and the nozzle 32 is T-shaped, thereby ensuring that the nozzle 32 will not fall off the adjusting member 31 with the water flow.

[0057] In this embodiment, there are two water flow channels, and two mounting slots 312 and two nozzles 32. At any given time, only one water flow channel communicates with the water outlet 221 of the shell. In other embodiments, there may be more water flow channels.

[0058] In this embodiment, the outer end face of each mounting slot 312 is a plane.

[0059] In this embodiment, the water flow channel includes a large-diameter section and a small-diameter section, with an installation groove 312 formed on the small-diameter section. The central cavity of the adjusting member 31 forms a common part of the two water flow channels.

[0060] In this embodiment, the outer shell 2 includes a cylindrical portion 21 and an end wall 22. The cylindrical portion 21 includes an internally threaded section and a smooth section, and the end wall 22 has the aforementioned shell water outlet hole 221.

[0061] In this embodiment, a first sealing ring 33 is provided between the adjusting member 31 and the end wall 22 of the outer shell 2, and a second sealing ring 34 is provided between the adjusting member 31 and the end face of the quick plug 1. The first sealing ring 33 seals the adjusting member 31 and the outer shell 2, and the second sealing ring 34 seals the adjusting member 31, the outer shell 2 and the quick plug 1.

[0062] In this embodiment, the adjustment component 3 has a linkage groove 311, and the control component 4 forms a linkage block 411 that cooperates with the linkage groove 311. Both the linkage groove 311 and the linkage block 411 have two parallel planes.

[0063] In this embodiment, the outer shell 2 extends radially outward to form a cylindrical control mounting portion 23. The control component 4 includes a control member 41 and a third sealing ring 42 that seals the control member 41 and the control mounting portion 23. The inner and outer ends of the control member 41 respectively form the aforementioned linkage block 411 and control portion 412. The control member 41 also forms a sealing ring mounting portion 413, and a sealing ring mounting groove 312 is provided on the sealing ring mounting portion 413.

[0064] In this embodiment, the adjusting component 3 swings relative to the outer casing 2, and the swing angle of the adjusting component 3 is less than 180°. Specifically, the swing angle of the adjusting component 3 is 90°.

[0065] In this embodiment, a swing angle limiting structure and a positioning structure are formed between the control member 41 and the control mounting part 23. The swing angle limiting structure restricts the swing angle of the control member 41, and the positioning structure positions the control member 41 to prevent movement. The positioning structure also enhances the operating feel.

[0066] In this embodiment, the swing angle limiting structure includes a limiting groove 231 on the control mounting part 23 and a limiting part 414 formed on the control member 41. The positioning structure includes a positioning groove 232 on the control mounting part 23 and a positioning rib formed on the control member 41. The positioning groove 232 is located on the circumferential bottom wall of the limiting groove 231. There are two limiting grooves 231 and two limiting parts 414. There are two sets of four positioning grooves 232 and two positioning parts 415. When the positioning part 415 enters the positioning groove 232, the user can clearly perceive it, thus accurately sensing that it has rotated to the correct position. Existing nozzles determine the gear position by different rotation feel, which is not easy to grasp.

[0067] In this embodiment, the different water outlets refer to differences in the diameter and / or number and / or shape of the water outlet holes. The required water output can be met by replacing different nozzles 32.

[0068] In this embodiment, the control part 412 of the control member 41 is flat and its length is greater than the diameter of other parts, so as to facilitate the observation of the angle of the control member 41 and the water output.

[0069] In this embodiment, the control component 41 is integrally formed. In other embodiments, the control component 41 can also be a component, such as the control part 412 of the control component 41 being detachably connected to other parts, thereby allowing the control part 412 to be removed, resulting in a smaller radial dimension of the nozzle and thus adapting to more scenarios.

[0070] In this embodiment, the control part 412 of the control member 41 is located radially, is relatively large, and is flat, making it easier to observe. Existing nozzles often use side markings when adjusting to the design setting; however, due to the small size of the nozzles, side markings are not easily observed.

[0071] The beneficial effects of the quick-connect rotary adjustable nozzle of Embodiment 1 of this utility model are as follows: the rotation axis of its control component 4 is perpendicular to the axis of the water outlet 221 of the outer shell 2, so the quick plug 1 will not rotate when the control component 4 is operated; the quick plug 1 enables quick connection; the entire nozzle outputs water in a straight line with low water resistance; the control part 412 of the control component 41 is located radially, is relatively large and flat, making it easier to observe; and the positioning part 415 and positioning groove 232 are provided, so that the rotation can be accurately sensed when it is in position.

[0072] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
