DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0027] The purpose of this specific embodiment is to provide a water-gas integrated cantilever device, which integrates an air supply passage and a water supply passage, and has two functions of water spraying and blowing. It can be used at will, thereby improving the convenience of operation and ease of use, and can save time to a certain extent and improve overall efficiency.

[0028] The following embodiments are described in detail with reference to the accompanying drawings. Furthermore, the embodiments described below do not limit the invention as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the invention as set forth in the claims.

[0029] Please refer to the attached Figure 1-7 , this embodiment provides a water-gas integrated cantilever device, including at least one cantilever, a water inlet 502 for communicating with a water source, and an air inlet 501 for communicating with an air source. The at least one cantilever is tubular and has an outlet connected to the tube cavity. The water inlet 502 can be directly opened on the cantilever or opened on other pipelines connected to the cantilever. The water inlet 502 connects the water source with a cantilever through a pipeline and forms a water supply passage for water to flow through; the air inlet 501 can also be directly opened on the cantilever or opened on other pipelines connected to the cantilever. The air inlet 501 connects the air supply device or the air source with a cantilever through a pipeline and forms an air supply passage for gas to pass through. When only one cantilever is provided, the cantilever can be shared by both the water supply passage and the air supply passage, with the air inlet 501 and the water inlet 502 respectively connected to the cantilever. When two cantilever arms are provided, one serves as a water supply cantilever 1 connected to the water inlet 502 and forming a water supply passage, and the other serves as a ventilation cantilever 2 connected to the air inlet 501 and forming an air supply passage. When a water supply device, such as a water pump, connecting the water inlet 502 to a water source is activated, a water spraying operation can be performed for watering or cleaning. When an air supply device connected to the air inlet 501 or an air supply device connecting the air inlet 501 to an air source is activated, a blowing operation can be performed for drying, etc.

[0030] With such an arrangement, the water-gas integrated cantilever device provided in this embodiment integrates two types of passages, namely water supply and air supply, and can perform both water spraying and air blowing operations for optional use, and can be completed by a single person in a single sequence, which significantly improves the convenience of operation and ease of use, and can save overall work time to a certain extent, thereby improving overall efficiency.

[0031] Furthermore, when the air inlet 501 is connected to a hot air blower, hot air can be blown to speed up the drying process. By adjusting the heating and cooling modes of the hot air blower, the user can choose to blow hot or cold air, thereby enhancing convenience.

[0032] like Figure 1 As shown, in this embodiment, two cantilevers are provided, one of which is configured as a water-passing cantilever 1 connected to the water inlet 502 for spraying water, and the other is configured as a ventilation cantilever 2 connected to the air inlet 501 for blowing air. This configuration prevents the two passages from interfering with each other, ensuring the dryness of the air supply passage, and allows the water spraying and blowing operations to be performed simultaneously, further improving convenience and overall efficiency.

[0033] The water-flow cantilever 1 and the ventilation cantilever 2 can be angled to facilitate independent operation without interference. In a preferred embodiment, the integrated water-gas cantilever assembly further includes an adjustment mechanism for adjusting the angle between the water-flow cantilever 1 and the ventilation cantilever 2. This arrangement allows the angle of the water-flow cantilever 1 and the ventilation cantilever 2 to be adjusted, as well as the distance between the two cantilever outlets, allowing for simultaneous operation of different objects. Alternatively, the two cantilever arms can be brought closer together, taking up less space and making them easier to store.

[0034] Specifically, the integrated water-gas cantilever assembly also includes a core shaft 5. One end of the water-flow cantilever 1 and / or the ventilation cantilever 2 is provided with a connecting sleeve fixedly connected to the cantilever itself. The one or both connecting sleeves are rotatably connected to the core shaft 5. Rotating the rotatably connected cantilever allows adjustment of the angle between the two cantilever arms and the spacing between the two cantilever outlets. In a preferred embodiment, both the water-flow cantilever 1 and the ventilation cantilever 2 are rotatably connected to the core shaft 5 via the connecting sleeve.

[0035] The connecting sleeve is arranged coaxially with the core shaft 5, and the ends of the water-passing cantilever 1 and the ventilation cantilever 2 can be connected to the peripheral side wall of the connecting sleeve. In order to prevent the two cantilevers from falling or falling off, or axially dislocated with the core shaft 5, an anti-slip structure is provided between the ventilation cantilever 2 and the water-passing cantilever 1 and the core shaft 5 to prevent axial dislocation and movement.

[0036] The air inlet 501 and the water inlet 502 can be directly opened on the corresponding ventilation cantilever 2 and water cantilever 1 respectively. Figure 4 and Figure 6 As shown, the water-gas integrated cantilever device also includes a water channel connecting pipe 52 and an air channel connecting pipe 51. The first end of the water channel connecting pipe 52 is set to the above-mentioned water inlet 502, and the second end is connected to the water cantilever 1. The first end of the air channel connecting pipe 51 is set to the above-mentioned air inlet 501, and the second end is connected to the ventilation cantilever 2.

[0037] The water channel connecting pipe 52 and the air channel connecting pipe 51 can be hoses or telescopic pipes. After being directly connected to the cantilever, their lengths can be adjusted accordingly when the cantilever rotates.

[0038] Alternatively, the core shaft 5 is a tubular structure, and the water channel connecting pipe 52 and the air channel connecting pipe 51 are both arranged in the tubular cavity of the connecting sleeve or the core shaft 5; at the same time, either the second ends of the two connecting pipes are connected to the corresponding cantilevers, and the first ends are coaxially arranged with the core shaft 5, that is, the two connecting pipes include a pipe section coaxially arranged with the core shaft 5 and a pipe section facing the cantilever, such as an L-shape, the air inlet 501 or the water inlet 502 is located in the axial direction of the core shaft 5, and the first end of the connecting pipe is rotatably connected to the pipe connected to the air source or water source, then, when the cantilever rotates, the connecting pipe rotates accordingly. Alternatively, at least one connecting tube is coaxially fixedly connected to the core shaft 5, and the cantilever corresponding to the connecting tube is rotatably connected to the connecting tube via a pipe joint 8, that is, one end of the pipe joint 8 is relatively fixedly connected to the corresponding cantilever, and the other end is rotatably connected to the second end of the connecting tube. The pipe joint 8 includes a pipe section coaxially arranged with the core shaft 5 and a pipe section facing the cantilever, such as an L-shaped or T-shaped pipe. The peripheral wall of the core shaft 5 is provided with an escape space for one end of the pipe joint 8 to rotate circumferentially. With such an arrangement, the cantilever can be rotated at any angle relative to the core shaft 5, and the various sections of the pipeline between the cantilever and the water source or gas source do not need to be arranged as hoses or telescopic tubes, and will not affect the rotation of the cantilever. The structure is simple, occupies little space, and is convenient for rotation operation.

[0039] In the preferred embodiment, the water cantilever 1 and the ventilation cantilever 2 are both rotatable relative to the core shaft 5. Figure 4 As shown, specifically, the water connection pipe 52 and the air connection pipe 51 can be a nested structure, and the two nested connection pipes are relatively fixed and form the main shaft section 511 of the core shaft 5. In this way, there is no need to provide an additional shaft pipe to wrap the two connection pipes, simplifying the structure. At the same time, the outer tube of the nested water connection pipe 52 and the air connection pipe 51 is used to be rotatably connected to the connecting sleeve, and the second end of the inner tube is rotatably connected to the corresponding cantilever through the pipe joint 8, that is, the pipe joint 8 is rotatably connected to the inner tube and relatively fixedly connected to the corresponding cantilever, so that the pipe joint 8 rotates with the cantilever.

[0040] For sealing considerations, the cantilever connected to the inner tube can be located above the cantilever connected to the outer tube and closer to the inner tube. Figure 5 and Figure 6As shown, the core shaft 5 also includes a reference section 512 spaced apart from the main shaft section 511. The connecting sleeve of one of the water-passing cantilever 1 and the ventilation cantilever 2 is rotatably sleeved on the main shaft section 511 and sleeved with one end of the reference section 512. The connecting sleeve of the other is rotatably sleeved on the reference section 512. The reference section 512 is a tubular structure and connects the outer tube with the other. The interval space between the reference section 512 and the main shaft section 511 is located in the tube cavity of the connecting sleeve and forms a rotation avoidance space 9 for the pipe joint 8 rotatably connected to the inner tube.

[0041] In order to facilitate sealing, the water connection pipe 52 is located in the tube cavity of the air connection pipe 51, that is, the water connection pipe 52 forms the above-mentioned inner tube, and the water-passing cantilever 1 is located above the ventilation cantilever 2 and closer to the water connection pipe 52. The connecting sleeve of the water-passing cantilever 1 is set as the first connecting sleeve 3, and the first connecting sleeve 3 is rotatably mounted on the air connection pipe 51 through a bearing. At the same time, the end of the first connecting sleeve 3 close to the pipe joint 8 is mounted on the reference section 512, and the reference section 512 is connected to the first connecting sleeve 3 through a fastener. The interval space between the reference section 512 and the main shaft section 511, that is, the rotation avoidance space 9, is located in the tube cavity of the first connecting sleeve 3. A first connecting hole 302 communicating with the pipe mouth of the water-passing cantilever 1 is opened on the tube wall of the first connecting sleeve 3. One end of the pipe joint 8 is rotatably and sealedly connected to the water connection pipe 52, and the other end is sealedly connected to the first connecting hole 302. The other end of the pipe joint 8 can be completely within the rotational clearance space 9, or partially within the rotational clearance space 9 and partially extend into the lumen of the reference section 512. The reference section 512 has a clearance hole in its wall. A sealing member, such as an annular sealing ring, can be provided between the pipe joint 8 and the first communication hole 302. When the water-passing cantilever 1 rotates, the first connecting sleeve 3, the reference section 512, and the pipe joint 8 rotate synchronously.

[0042] The reference section 512 is tubular and located below the second end of the air duct connecting tube 51. The connecting sleeve of the ventilation arm 2 is configured as the second connecting sleeve 4, and the wall of the second connecting sleeve 4 is provided with a second connecting hole 402 that connects to the pipe opening of the ventilation arm 2. The end of the reference section 512 near the air duct connecting tube 51 is open, allowing the tube lumen to communicate with the lumen of the air duct connecting tube 51 through the rotational escape space 9. A bearing located above the rotational escape space 9 and between the first connecting sleeve 3 and the air duct connecting tube 51 seals this side of the rotational escape space 9. Alternatively, the end of the first connecting sleeve 3 near the air inlet 501 can be sealed. Thus, after gas flowing out of the second end of the air duct connecting tube 51 enters the rotational escape space 9, it enters the lumen of the reference section 512 below, with the rotational escape space 9 sealed above and the first connecting hole 302 sealed. This arrangement provides a reasonable and simple structure and effectively prevents gas leakage.

[0043] The end of the reference section 512 away from the air path connecting pipe 51 can be in a closed state, and a through hole connected to the second connecting sleeve is provided on the pipe wall of the reference section 512. Alternatively, the end of the reference section 512 away from the air path connecting pipe 51 can also be open, such as Figure 5 and Figure 7 As shown, the integrated water-gas cantilever device also includes a bottom plug 7 spaced apart from the reference section 512. The bottom plug 7 comprises a plug ring 71 and a plug cap 72 capping one end of the plug ring 71. One end of the second connecting sleeve 4 on the ventilation cantilever 2 is sleeved around the plug ring 71 and capped by the plug cap 72. The other end is rotatably sleeved and connected to the reference section 512 via a bearing or sleeve. The space between the bottom plug 7 and the reference section 512 is connected to the second connecting hole 402. Gas enters this space through the lumen of the reference section 512 and then enters the ventilation cantilever 2 through the second connecting hole 402.

[0044] In order to prevent the bottom plug 7 from falling and to enhance the connection stability between the bottom plug 7 and the second connecting sleeve 4, a snap-fit ​​protrusion 701 is provided on the outer peripheral wall of the plug ring 71, and a snap-fit ​​groove 401 for the snap-fit ​​protrusion 701 to be embedded in the inner wall of the second connecting sleeve 4 is provided. The second connecting sleeve 4 is made of a rigid metal material, and the plug ring 71 can be provided with an elastic opening structure that can adjust the diameter of the plug ring 71 opening. Figure 7 As shown, the elastic opening structure can be configured as follows: the plug ring 71 includes multiple spaced segments along the circumference. The circumferential spacing between adjacent segments can form an elastic space for tightening or resetting the plug ring 71. The ends of each segment near the ring opening can also be tapered, with the outer peripheral wall of the end forming an inclined slope. The bottom plug 7 can be made of plastic.

[0045] Some ring segments are provided with a locking protrusion 701, located at the end of the ring segment near the ring opening. The sidewall of the locking protrusion 701 near the ring opening is also inclined, further connecting with the inclined surface at the end of the ring segment to form a single unit. This facilitates the insertion and engagement of the bottom plug 7 with the second connecting sleeve 4. The sidewall of the locking protrusion 701 near the plug cap 72 extends radially to form a stepped surface. The groove wall of the locking groove 401 also extends radially to form a stepped surface. When the locking protrusion 701 is inserted into the locking groove 401, the two stepped surfaces abut against each other, enhancing the connection stability.

[0046] After the air connection pipe 51 and the water connection pipe 52 are nested together, their second ends are connected to the cantilever through the pipe joint 8 and the reference section 512, respectively. The first end is used to connect to the air or water source. To avoid interference, the first end of the water connection pipe 52 is arranged radially along the air connection pipe 51 and penetrates the pipe wall of the air connection pipe 51 to form the water inlet 502. The air connection pipe 51 is a straight pipe with an axially open first end forming the air inlet 501. A connecting rib 53 extending axially and connecting the outer circumferential wall of the water connection pipe 52 and the inner circumferential wall of the air connection pipe 51 can be provided between the water connection pipe 52 and the air connection pipe 51 to secure the water connection pipe 52.

[0047] The water inlet 502 of the water connection pipe 52 is connected to the water pipe and connected to the pressurized water flow. The air inlet 501 of the air connection pipe 51 can be connected to the air pipe and connected to the pressurized air source, or the air inlet 501 of the air connection pipe 51 is directly connected to the fan. In this embodiment, the water-gas integrated cantilever device also includes a support plate 6 connected to the first end of the air connection pipe 51. The support plate 6 can be arranged along the radial direction of the air connection pipe 51 and can be sleeved on the air connection pipe 51. The first end of the air connection pipe 51 passes through the support plate 6. The air inlet 501 is located on the side of the support plate 6 away from the cantilever, so that the fan can be placed on the support plate 6, and the air inlet 501 is convenient for connecting to the air outlet end of the fan. Furthermore, the water-gas integrated cantilever device also includes a hot air blower placed and connected to the support plate 6, and the support plate 6 is also provided with a connection hole for the hot air blower to be connected; the hot air blower can blow hot air to speed up the drying rate, and the hot air blower itself has two modes of heating and cooling, so that the water-gas integrated cantilever device can blow both hot air and cold air, with strong operational options, multiple modes, and strong convenience.

[0048] The air channel connecting pipe 51 , the water channel connecting pipe 52 , the connecting ribs 53 and the supporting plate 6 may be integrally formed by injection molding.

[0049] The anti-slip structure between the core shaft 5 and the first connecting sleeve 3 and the second connecting sleeve 4 can be configured as follows: a retaining ring is provided between the air duct connecting pipe 51 and the first connecting sleeve 3, the retaining ring being sleeved on the air duct connecting pipe 51, and a first groove 301 for the radially outer end of the retaining ring to be inserted into is provided on the inner tube wall of the first connecting sleeve 3, and the retaining ring is rotatable relative to the first connecting sleeve 3 or the air duct connecting pipe 51; similarly, the same structure is provided between the second connecting sleeve 4 and the reference section 512, and the two are also axially positioned by the retaining ring. Furthermore, a second groove 503 for the retaining ring to be inserted into is provided on the outer tube wall of the air duct connecting pipe 51, and the second groove 503 is provided with two, one located at the two axially outer ends of each bearing corresponding to the first connecting sleeve 3.

[0050] Both the ventilation cantilever 2 and the water-passing cantilever 1 can be straight tube structures, with the outlet ends forming an air outlet or a water outlet, respectively; alternatively, one or both outlet ends can be connected to a hose and / or a spring tube, with the nozzle at the end of the pipe forming the air outlet or the water outlet. This arrangement facilitates adjustment of the angle and position of the air outlet and the water outlet without moving the cantilever, requiring only adjustment of the hose and / or spring tube. The hose and / or spring tube can be rotatably connected to the outlet end, or can be detachably connected to the outlet end by means of a snap connection or a threaded connection.
