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.

[0005] To address the nozzle slippage problem, the applicant designed a structure with an adjustment component containing multiple different water flow channels within the casing. The water flow rate is adjusted by rotating this component. However, this structure has two drawbacks: 1. When the nozzle inlet is not closed, the water jets from the water flow channels will spray onto the nozzles in the casing during the rotation of the adjustment component, causing erratic water flow; 2. It cannot shut off the nozzle's water flow. Summary of the Invention

[0006] This invention addresses the shortcomings of existing quick-connect adjustable nozzles, where the axis of adjustment rotation is parallel to the axis of the quick-connect direction, making the nozzle prone to slippage during rotation adjustment or causing water to splatter erratically during adjustment. It provides a quick-connect rotary adjustable nozzle that alters the water outlet adjustment structure to prevent nozzle slippage during adjustment and avoid erratic water flow.

[0007] 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:

When operating the control component, the quick-connect plug will not rotate, thus avoiding slippage. The nozzle is always fixed in the shell water outlet channel of the shell, and there will be no water spraying during the adjustment process. It can achieve simultaneous closure of both shell water outlet channels.

[0018] As an improvement, the two ends of the plug abut against the nozzle and the quick connector respectively, and the plug forms a connected axial hole and a radial hole. The axial hole connects to the nozzle, and the radial hole connects to the radial hole of the nozzle assembly mounting part.

[0019] As an improvement, a plug sealing ring is provided between the plug and the axial hole of the nozzle assembly mounting part; the nozzle is T-shaped with a smaller outer end and a larger inner end, and the axial hole of the nozzle assembly mounting part is a stepped hole.

[0048] The quick-connect rotary adjustable nozzle of this invention has a shell water inlet channel and a shell water outlet channel that are parallel (usually also parallel to the channel in the quick-connect plug). The rotation axis of the control component is perpendicular to the axis of the shell water inlet channel.

It can achieve simultaneous closure of both shell water outlet channels.

[0049] Example 1

[0050] See Figures 1 to 9 The quick-connect rotary adjustable nozzle of Embodiment 1 of this utility model includes:

[0051] The outer shell 1 has a shell water flow channel, which includes a shell water inlet channel and two shell water outlet channels;

[0052] Quick connector 2 is fixedly connected to the water inlet channel of the housing;

[0053] Nozzle assembly 3 includes two different nozzles, which are located in two shell water outlet channels respectively;

[0054] Adjustment component 4 is rotatably disposed in housing 1;

[0055] The control component 5 is linked to the adjustment component 4 and has a control part located outside the housing 1;

[0056] Among them, the shell inlet channel and the shell outlet channel are parallel, and the rotation axis of the control component 5 is perpendicular to the axis of the shell inlet channel.

[0057] Among them, the adjustment component 4 has an adjustment channel, which is always connected to the shell inlet channel, and the adjustment channel is connected to the two shell outlet channels respectively by rotation.

[0058] In this embodiment, the two nozzles are a direct spray nozzle 31 and a fan spray nozzle 32. In other embodiments, the number of water outlet channels and nozzles can be even greater.

[0059] In this embodiment, since there are only two nozzles, the adjusting component 4 needs to rotate 180° for each adjustment. In other embodiments, when there are three nozzles, the adjusting component 4 rotates 90°, 180°, and 270° respectively to switch the nozzle from being connected to the first nozzle, the second nozzle, the third nozzle, or neither nozzle is connected.

[0060] In this embodiment, the outer casing 1 includes an axial portion 11 and an adjustment assembly mounting portion 12. The outlet end of the axial portion 11 forms a sealing portion 13, and the sealing portion 13 extends towards the inlet end of the axial portion 11 to form a nozzle assembly mounting portion 14. The nozzle assembly mounting portion 14 has two axial holes 141 and a radial hole 142 connecting the axial holes 141, forming the aforementioned casing water outlet channel. The axial portion 11 is tubular, and the inlet end of the axial portion 11 forms the aforementioned casing water inlet channel. The outer casing 1 is generally T-shaped.

[0061] In this embodiment, the two axial holes 141 of the nozzle assembly mounting part 14 are connected. The nozzle is installed at the outlet end of the nozzle assembly mounting part 14 from the water inlet direction to the water outlet direction. A plug 33 is provided at the end of the two axial holes 141 near the quick connector 2, and the end of the plug 33 near the quick connector 2 is closed. The two axial holes 141 of the nozzle assembly mounting part 14 are connected, so that the nozzle can be installed at the outlet end of the nozzle assembly mounting part 14 from the water inlet direction to the water outlet direction, instead of from the water outlet direction to the water inlet direction. After the axial holes 141 are connected, it is necessary to close the non-outlet end, so the plug 33 is used to close this end.

[0062] In this embodiment, the two ends of the plug 33 abut against the nozzle and the quick-connect plug 2, respectively. A axial hole 331 and a radial hole 332 are formed in the plug 33, with the axial hole 141 connecting to the nozzle and the radial hole 332 connecting to the radial hole 142 of the nozzle assembly mounting part 14. Because the plug 33 is not reliably fixed, its two ends abut against the nozzle and the quick-connect plug 2, thus requiring the formation of a water flow channel within the plug 33.

[0063] In this embodiment, a plug sealing ring 34 is provided between the plug 33 and the axial hole 141 of the nozzle assembly mounting part 14 to prevent water from flowing back into the shell water inlet channel.

[0064] In this embodiment, the upper part of the nozzle assembly mounting part 14 is integrated with the axial part 11. A process groove 131 is provided at the sealing part 13 to prevent shrinkage marks from occurring when the mold is processed into the outer shell 1.

[0065] In this embodiment, the outer shell 1 is integrally formed.

[0066] In this embodiment, the nozzle is T-shaped with a smaller outer end and a larger inner end. The axial hole 141 of the nozzle assembly mounting part 14 is a stepped hole, which prevents the nozzle from falling out.

[0067] In this embodiment, the axis of the radial hole 142 is parallel to the axis of the adjustment assembly mounting part 12.

[0068] In this embodiment, an interference rib 144 extends into the axial hole 142, causing the nozzle to be in an interference fit with the axial hole 142. The interference rib 144 is located adjacent to the water outlet end of the axial hole 142.

[0069] In this embodiment, the two axial holes 331 connecting the two nozzles are different. To avoid installation errors, the inlet ends of the two plugs 33 in the nozzle assembly mounting part 14 are connected as one unit and extended to form a foolproof part 333. A foolproof rib 145 is formed on the nozzle assembly mounting part 14. That is, a U-shaped plug 33 is used to simultaneously block the two axial holes 141 of the nozzle assembly mounting part 14. In other embodiments, other foolproof structures may also be used.

[0070] In this embodiment, the adjustment component 4 includes a rotating adjustment member 41, which includes a circular portion 411. An adjustment water hole 412 is formed on the circular portion 411, creating the aforementioned adjustment channel. The rotating adjustment member 41 is sealed to the radial hole 142 of the nozzle assembly mounting portion 14, preventing water from flowing simultaneously from the rotating adjustment member 41 and the nozzle assembly mounting portion 14 to both radial holes 142 and the shell inlet channel. The size of the adjustment water hole 412 is the same as the size of the radial hole 142 of the nozzle assembly mounting portion 14.

[0071] In this embodiment, an adjustment sealing groove 143 is provided on the outer surface of the two radial holes 142 of the nozzle assembly mounting part 14, and an adjustment sealing ring 42 is provided in the adjustment sealing groove 143; the adjustment assembly mounting part 12 includes a threaded hole post, and a pressure ring 43 is provided in the threaded hole post and threadedly connected thereto. The pressure ring 43 abuts against the circular part 411 of the rotating adjustment member 41, and the pressure ring 43 and the threaded hole post are sealed.

[0072] In this embodiment, the inner end of the pressure ring 43 is an incomplete circular ring, and the water flows through the gap in the incomplete circular ring into the adjusting water hole 412 of the rotating adjusting member 41. Specifically, the incomplete circular ring has four protrusions and four notches.

[0073] In this embodiment, a pressure ring sealing ring 44 is provided between the pressure ring 43 and the threaded hole of the adjustment component mounting part 12 of the outer shell 1.

[0074] In this embodiment, the rotating adjustment component 41 further includes a columnar portion 413. A ring hole is formed at the center of the pressure ring 43, which is located within the ring hole. A rotating sealing ring 45 is provided between the columnar portion 413 and the ring hole. The outer end of the columnar portion 413 is located outside the ring hole, and the outer end of the columnar portion 413 is connected to the anti-rotation connection of the control component 5. There are two rotating sealing rings 45.

[0075] In this embodiment, the control component 5 includes a control member 51 and a screw 52. The screw 52 passes through the control member 51 and is screwed into the rotation adjustment member 41. The cross-section of the outer end of the columnar part 413 is a large cut circle, and the control member 51 has a large cut circle groove.

[0076] In this embodiment, a sealing ring is also provided between the quick connector 2 and the outer shell 1. The structure of the quick connector 2 can refer to the prior art, and will not be described in detail here.

[0077] In this embodiment, during assembly, the two nozzles are first pressed into the two axial holes 141 of the housing 1 by interference fit, the plug 33 with the plug sealing ring 34 is inserted into the two axial holes 141 of the housing 1, and the quick plug 2 is screwed into the water inlet end of the housing 1. Then, the adjusting sealing ring 42 is placed in the two adjusting sealing grooves 143 of the adjusting component mounting part 12 of the housing 1, the rotating adjusting member 41 with the rotating sealing ring 45 pre-installed is placed on the adjusting sealing ring 42, and then the pressure ring 43 with the pressure ring sealing ring 44 pre-installed is screwed into the threaded hole post of the adjusting component mounting part 12 of the housing 1. Finally, the operating member is sleeved on the outer end of the rotating adjusting member 41 and the operating member and the rotating adjusting member 41 are fastened with screws 52.

[0078] The water flow adjustment process in this embodiment is as follows: Initially, the adjusting water hole 412 of the rotating adjusting member 41 is located at the position connecting to the fan nozzle 32. At this time, the operating part of the operating member is aligned with the axial direction of the outer casing 1. During adjustment, the operating member is rotated, and the rotating adjusting member 41 rotates with the operating member. After rotating 180°, the adjusting water hole 412 of the rotating adjusting member 41 reaches the position connecting to the direct spray nozzle 31. Throughout the adjustment process, the nozzle remains fixed, thus preventing water from spraying erratically. (See also...) Figure 9 When the adjusting water hole 412 of the rotating adjusting hole is completely misaligned with the two radial holes 142 of the nozzle assembly mounting part 14, the water flow channel inside the nozzle is basically closed, and the nozzle will basically not emit water (the angle at which water will basically not emit is greater than 90°). When the adjusting water hole 412 of the rotating adjusting hole is located outside the highest point (circumferential center line) of the adjusting sealing ring 42, the nozzle will not emit water (the angle at which water will not emit at all is about 60°). Therefore, the nozzle will not emit water without closing the main body of the cleaning machine.

[0079] The beneficial effects of the quick-connect rotary adjustable nozzle of Embodiment 1 of this utility model are as follows: the water inlet channel and the water outlet channel of the shell are parallel (usually also parallel to the channel in the quick-connect plug 2), the rotation axis of the control component 5 is perpendicular to the axis of the water inlet channel of the shell, and the quick-connect plug 2 will not rotate when the control component 5 is operated, thus avoiding slippage; the nozzle is always fixed in the water outlet channel of the shell 1, and there will be no water spraying during the adjustment process; both water outlet channels of the shell can be closed at the same time, and the nozzle will not spray water without closing the main body of the cleaning machine; assembly is easy and maintenance is convenient.

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.
