Description

Technical Field

[0001] This disclosure relates to the field of stage technology, and more specifically, to a spraying device. Background Technology

[0002] Currently, during stage performances, it is common practice to use spray equipment to create mist on the stage in order to enhance the performance effect.

[0003] However, actors may experience discomfort from holding the spray device for extended periods during the spraying process, which can negatively impact the stage performance.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this disclosure is to provide a spraying device that, through a designed grip structure, facilitates the user's gripping of the spraying device.

[0006] According to one aspect of this disclosure, a spraying device is provided, the spraying device comprising:

[0007] A pressure pipe, wherein a gripping structure is provided on the pressure pipe, and the surface of the gripping structure protrudes from the surface of the pressure pipe along the radial direction of the pressure pipe;

[0008] Multiple nozzles are connected to the pressure conduit, and the gripping structure is located between two adjacent nozzles along the axial direction of the pressure conduit.

[0009] In one exemplary embodiment of this disclosure, the gripping structure includes a sleeve that is fitted and fixed onto the pressure pipe.

[0010] In one exemplary embodiment of this disclosure, the gripping structure includes a first clamping portion and a second clamping portion, the first clamping portion and the second clamping portion being radially connected and clamped on the pressure pipe, and the first clamping portion and the second clamping portion being detachably connected.

[0011] In one exemplary embodiment of this disclosure, the inner diameter of the pressure pipe is 7 mm to 9 mm.

[0012] In one exemplary embodiment of this disclosure, the nominal diameter of the pressure pipe is 9 mm to 10 mm.

[0013] In one exemplary embodiment of this disclosure, the spray setting further includes:

[0014] A connector, which is connected to the plurality of nozzles and is spaced apart from the pressure conduit in the radial direction of the pressure conduit.

[0015] In one exemplary embodiment of this disclosure, the connector is detachably connected to the plurality of nozzles.

[0016] In one exemplary embodiment of this disclosure, the plurality of nozzles are distributed along the axial direction of the pressure conduit and are located at the same position in the circumferential direction of the pressure conduit.

[0017] In one exemplary embodiment of this disclosure, the spraying device further includes:

[0018] Multiple connecting pipes are provided, each corresponding to one of the multiple nozzles, and each nozzle is connected to the pressure pipeline through one of the connecting pipes.

[0019] In one exemplary embodiment of this disclosure, the inner diameter of the connecting pipe is less than or equal to the inner diameter of the pressure pipe.

[0020] The spraying device disclosed herein, by employing a thinner pressure pipe, can increase the water pressure per unit time within the pressure pipe, thereby generating a larger pressure difference at the nozzle. This results in a better atomization effect for the water mist sprayed from the nozzle, enhancing the stage effect. However, a thinner pressure pipe is not conducive to the actor's grip. By incorporating a thicker grip structure on the pressure pipe, ergonomic principles can be better utilized, making it more comfortable for the actor to hold the spraying device.

[0021] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0027] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0028] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0029] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0030] This disclosure provides a spraying device, such as... Figure 1 and Figure 2 As shown, the spraying device includes a pressure pipe 10 and multiple nozzles 20, with the nozzles 20 connected to the pressure pipe 10. After the pressure pipe 10 is connected to the liquid supply device, water at a preset pressure can be injected into the pressure pipe 10. When the water at the preset pressure in the pressure pipe 10 is sprayed out through the nozzles 20, it can form a water mist, thereby achieving the purpose of creating water mist in target scenes such as stages.

[0031] Among them, such as Figure 1 and Figure 2As shown, multiple nozzles 20 are distributed along the axial direction X of the pressure pipe 10 and are located at the same position in the circumferential direction of the pressure pipe 10. By simultaneously generating mist with multiple nozzles 20, the misting efficiency can be improved and the coverage area of ​​the water mist can be increased. Of course, the multiple nozzles 20 can be located at different positions in the circumferential direction of the pressure pipe 10 to form multi-angle misting.

[0032] In this configuration, multiple nozzles 20 are evenly distributed along the axial direction X of the pressure pipe 10, meaning that the gaps between adjacent nozzles 20 are the same or substantially the same, in order to improve the uniformity of mist generation. Of course, the gaps between adjacent nozzles 20 may also be different, meaning that the multiple nozzles 20 are not evenly distributed along the axial direction X of the pressure pipe 10, and this disclosure does not impose any restrictions on this.

[0033] Specifically, the nominal diameter DN of the pressure pipe 10 can be 9mm to 10mm, such as 9mm, 9.1mm, 9.2mm, 9.3mm, 9.4mm, 9.5mm, 9.6mm, 9.7mm, 9.8mm, 9.9mm, 10mm, etc., which will not be listed here. By allowing the inner diameter of the pressure pipe 10 to be relatively small, while keeping the supply pressure of the connected liquid supply equipment constant, using a smaller pressure pipe 10 can increase the water outlet pressure per unit time of the pressure pipe 10, thereby generating a larger pressure difference at the nozzle 20. This results in better atomization of the water mist sprayed from the nozzle 20, thus enhancing the stage effect.

[0034] In cases where the nominal diameter of the pressure pipe 10 can be 9mm to 10mm, the inner diameter of the pressure pipe 10 can be 7mm to 9mm, such as 7mm, 7.2mm, 7.5mm, 7.8mm, 8mm, 8.2mm, 8.5mm, 8.5mm, and 9mm, which will not be listed here. The pressure pipe 10 with an inner diameter of 7mm to 9mm is relatively thin. With the supply pressure of the connected liquid supply equipment remaining constant, using a 7mm to 9mm pressure pipe 10 can increase the water outlet pressure per unit time, thereby generating a larger pressure difference at the nozzle 20. This results in better atomization of the water mist sprayed from the nozzle 20, enhancing the stage effect.

[0035] like Figure 1 and Figure 2 As shown, the spray setup also includes multiple connecting pipes 30, each corresponding to a single nozzle 20. Each nozzle 20 is connected to the pressure pipe 10 via a connecting pipe 30. The connecting pipes 30 facilitate the connection between the nozzles 20 and the pressure pipe 10, and also facilitate the placement of the multiple nozzles 20 on the pressure pipe 10.

[0036] The connecting pipe 30 and the pressure pipe 10 can be fixedly connected together by welding, and the nozzle 20 and the corresponding connecting pipe 30 can be fixedly connected together by threaded connection. The threaded connection between the nozzle 20 and the connecting pipe 30 facilitates the assembly of the nozzle 20; it also facilitates the replacement and maintenance of the nozzle 20 when it malfunctions due to long-term use or storage; and it facilitates the replacement of the nozzle 20 when the atomization effect needs to be adjusted, i.e., when replacing it with a nozzle 20 with a better atomization effect, thus achieving modularity of the spraying equipment. Of course, the nozzle 20 and the connecting pipe 30 can also be connected by welding, and this disclosure does not impose any restrictions on this.

[0037] It is understood that the nozzle 20 can also be directly connected to the pressure pipe 10, that is, the nozzle 20 can be directly connected to the pressure pipe 10 by means of threaded connection, welding, bonding, etc., and this disclosure does not limit this.

[0038] The inner diameter of the connecting pipe 30 is less than or equal to the inner diameter of the pressure pipe 10. By making the inner diameter of the connecting pipe 30 less than or equal to the inner diameter of the pressure pipe 10, the water pressure of the connecting pipe 30 per unit time can be greater than or equal to the water pressure of the pressure pipe 10 per unit time. This ensures a greater pressure difference at the nozzle 20, resulting in better atomization of the water mist sprayed from the nozzle 20 and enhancing the stage effect.

[0039] The nominal diameter DN of the connecting pipe 30 can be 9mm to 10mm, such as 9mm, 9.1mm, 9.2mm, 9.3mm, 9.4mm, 9.5mm, 9.6mm, 9.7mm, 9.8mm, 9.9mm, 10mm, etc., which are not listed here. When the nominal diameter of the connecting pipe 30 is 9mm to 10mm, the inner diameter of the connecting pipe 30 can be 7mm to 9mm, such as 7mm, 7.2mm, 7.5mm, 7.8mm, 8mm, 8.2mm, 8.5mm, 8.5mm, 9mm, which are not listed here.

[0040] The connecting pipe 30 can be the same as the pressure pipe 10, meaning that the same material can be used to cut both pipes during manufacturing. This improves manufacturing efficiency and reduces the manufacturing cost of the spraying equipment. It also helps control the dimensional consistency of the connecting pipe 30 and the pressure pipe 10, ensuring the atomization effect of the water mist sprayed from the nozzle 20. Furthermore, using the same material to cut the connecting pipe 30 and the pressure pipe 10 facilitates welding. Welding a connecting pipe 30 and a pressure pipe 10 made of the same material results in a stronger connection, extending the service life of the spraying equipment. Of course, the connecting pipe 30 and the pressure pipe 10 can also be made of different materials; this disclosure does not impose any restrictions on this.

[0041] For example, such as Figure 1 and Figure 2 As shown, six nozzles 20 can be connected to the pressure pipe 10. Each of the six nozzles 20 is connected to the pressure pipe 10 through a connecting pipe 30, meaning there are six connecting pipes 30 on the pressure pipe 10. The number of nozzles 20 on the pressure pipe 10 can be adjusted as needed, for example, three, four, five, seven, eight, or more can be provided, and this disclosure does not impose any limitations on this.

[0042] It should be noted that the pressure pipe 10 and connecting pipe 30 mentioned above are circular pipes, and the inner hole they form is a circular hole. They can also be replaced with elliptical pipes, square pipes, or irregularly shaped pipes. When the shape of their inner hole matches their outer shape, it is sufficient to ensure that the cross-sectional area of ​​their inner hole is the same as the cross-sectional area of ​​the inner hole of the circular pipe as specified above.

[0043] like Figure 1 and Figure 2 As shown, the spray setup also includes a connector 40, which connects to multiple nozzles 20 and is radially spaced from the pressure conduit 10. The connector 40, in conjunction with the pressure conduit 10, positions the multiple nozzles 20 between the connector 40 and the pressure conduit 10, thus protecting the nozzles 20 and preventing them from being accidentally stepped on and damaged when placed on the stage. Simultaneously, the connector 40 prevents actors or staff from stepping on the nozzles 20 and injuring them, thus providing protection for the actors and staff.

[0044] Among them, such as Figure 1 and Figure 2 As shown, the connector 40 includes a first connecting structure 410 and a second connecting structure 420. The first connecting structure 410 is funnel-shaped, with a smaller size near the nozzle 20 and a larger size away from the nozzle 20. This design avoids excessive interference between the first connecting structure 410 and the spray from the nozzle 20, facilitating the dispersion of water mist. Each nozzle 20 is connected to a first connecting structure 410, providing protection for each nozzle 20. The second connecting structure 420 connects multiple first connecting structures 410 together to form an integrated frame structure, thereby improving the structural strength of the connector 40.

[0045] The second connecting structure 420 is detachably connected to the nozzle 20 or the connecting pipe 30 to facilitate the assembly of the connector 40 and its disassembly when replacing the nozzle 20. In other words, the connector 40 is detachably connected to multiple nozzles 20. The second connecting structure 420 can be detachably connected to the nozzle 20 or the connecting pipe 30 using fasteners 50, such as set screws. The second connecting structure 420 forms an annular sleeve structure that can be fitted onto the nozzle 20 or the connecting pipe 30. Then, the set screw passes through the threaded hole in the sleeve structure and abuts against the nozzle 20 or the connecting pipe 30 to form a fixed connection. Multiple set screws can be provided and distributed circumferentially along the nozzle 20 or the connecting pipe 30 to improve the reliability of the connection.

[0046] The first connecting structure 410 further includes a connecting ring and first connecting rods. The connecting ring is connected to the annular sleeve structure via multiple first connecting rods, which are radially distributed to form a flared structure with an enlarged opening. The first connecting structures 410 connected to multiple nozzles may be identical or different. The connecting ring and the first connecting rods can be fixed together by welding, snap-fit, threaded connection, or other methods.

[0047] The second connecting structure 420 includes a second connecting rod, which connects to connecting rings of multiple first connecting structures 410 to form a single frame structure. The extension direction of the second connecting rod can be parallel or substantially parallel to the extension direction of the pressure pipe 10. Two second connecting rods can be provided, distributed on both sides of the connecting ring to enhance the connection strength. The second connecting rod and the connecting ring can be fixed together by welding, snap-fit, threaded connection, or other methods.

[0048] like Figure 1 and Figure 2 As shown, the connector 40 also includes a third connecting structure 430, which connects multiple second connecting rods to further enhance the structural strength of the overall frame structure.

[0049] The third connecting structure 430 may include a third connecting rod, which connects two adjacent second connecting rods to enhance the structural strength between the second connecting rods. The third connecting rod and the second connecting rods may be fixed together by welding, snap-fitting, threaded connection, or other methods.

[0050] In particular, a third connecting rod can be provided between adjacent nozzles 20 along the axial X of the second connecting rod to further enhance the structural strength of the connecting member 40 of the frame structure.

[0051] The structural components in connector 40 can be made of metal, possessing high structural strength and facilitating welding connections between them. The first, second, and third connecting rods can be formed from the same metal rod, improving manufacturing efficiency and reducing equipment manufacturing costs. Alternatively, the components in connector 40 can be made of composite or non-metallic materials, and the materials used for each component can be the same or different; this disclosure does not impose any limitations in this regard.

[0052] Specifically, the pressure pipe 10 is equipped with a grip structure, the surface of which protrudes from the surface of the pressure pipe 10 along its radial direction. Using a thinner pressure pipe 10 increases the water pressure per unit time, thereby generating a larger pressure difference at the nozzle 20. This results in better atomization of the water mist sprayed from the nozzle 20, enhancing the stage effect. However, a thinner pressure pipe 10 is not conducive to the actor's grip. By providing a thicker grip structure on the pressure pipe 10, ergonomic principles can be better utilized, making it more comfortable for the actor to hold the spraying device.

[0053] The gripping structure may include a sleeve, which is fitted and fixed onto the pressure pipe 10. During the manufacturing of the spraying equipment, a sleeve with a larger diameter can be fitted onto the pressure pipe 10, allowing the actor to control the posture of the spraying equipment by gripping the sleeve, thus facilitating the actor's grip. The sleeve can be connected to the pressure pipe 10 by welding, bonding, snap-fitting, or other methods.

[0054] The gripping structure includes a first clamping part and a second clamping part. During assembly, the first and second clamping parts are radially connected and clamped onto the pressure pipe 10. The first and second clamping parts are detachably connected, facilitating assembly. This also facilitates replacement of the gripping structure after prolonged use of the spraying equipment, reducing maintenance costs.

[0055] The first clamping part and the second clamping part can be connected together by a threaded part or by a snap-fit ​​structure. The first clamping part and the second clamping part can be made of wood or plastic. Ergonomic structures can be set on the first clamping part and the second clamping part to improve the feel of the actor's grip and reduce fatigue during long-term gripping.

[0056] The grip structure can be positioned where the actor typically holds the cleaning equipment, such as near the first end 110 of the pressure pipe 10, or in the middle of the pressure pipe 10. The position of the grip structure on the pressure pipe 10 is adjustable; it can be disassembled and reinstalled to meet different gripping requirements.

[0057] The second end 120 of the pressure pipe 10 can be quickly connected to the interface of the liquid supply equipment on the stage. When the spraying equipment is needed, the actor connects the second end 120 of the spraying equipment to the interface on the stage using a plug-in quick-connect method, starts the liquid supply equipment to inject water at a preset pressure into the pressure pipe 10, and then sprays water through the nozzle 20. After the spraying equipment is used, the actor can disconnect the second end 120 of the pressure pipe 10 from the interface on the stage and place the spraying equipment horizontally on the stage for the next use. Because the spraying equipment is equipped with a connector 40, it protects the nozzle 20, preventing it from being accidentally stepped on and damaged when placed on the stage; at the same time, it prevents actors or staff from stepping on the nozzle 20 and getting injured, thus protecting the actors and staff and improving the safety of the spraying equipment.
