Description

Technical Field

[0001] This utility model relates to the field of spray technology, and in particular to a detachable external spray device and fan. Background Technology

[0002] In high-temperature environments, misting devices are typically clipped to the fan shroud. The misting device sprays water mist, which the fan amplifies and increases airflow, thus lowering the ambient temperature. Figure 1 As shown, the fan shroud 2 generally includes a concentric circular circumferential frame 201 with a diameter gradually increasing from the inside to the outside, and several radial frames 202 radiating radially from the center of the shroud. The prior art spray device 1 includes a spray pipe, an input pipe, and an annular housing. The spray pipe converts water introduced from the input pipe into a spray and sprays it into the environment. The spray pipe is fixed to the annular housing. The annular housing is also provided with a fixing member that can slide circumferentially along its circumference. The annular housing is fixed to the circumferential frame 201 or radial frame 202 of the fan shroud 2 by the fixing member.

[0003] However, the current spray device 1 is still not flexible enough to adapt to different fans. Utility Model Content

[0004] Therefore, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide a spraying device.

[0005] A spraying device includes an annular housing; one side of the annular housing is provided with a plurality of fixing members, each fixing member including a circumferential sliding seat and a fixing clamp slidably disposed on the circumferential sliding seat, the circumferential sliding seat being slidable along the circumference of the annular housing, and the fixing clamp being slidable along the radial direction of the annular housing; the other side of the annular housing is provided with a plurality of through holes spaced apart circumferentially; a notch is provided on the outer sidewall of the annular housing; a spraying pipe is disposed inside the annular housing, and a plurality of nozzles are spaced apart on it, the position of each nozzle corresponding to a through hole on the annular housing; an input pipe is connected to the spraying pipe at the notch of the annular housing.

[0006] Compared to existing technologies, the fixing clip of this spray device can be adjusted both circumferentially and radially, making it compatible with a wider range of fan covers.

[0007] In some embodiments, the annular housing has a circumferential guide rail on one side where the fixing member is located; the circumferential sliding seat of the fixing member has a circumferential sliding groove, and the circumferential sliding seat is fixed to the annular housing by the snap-fit ​​of the circumferential sliding groove and the circumferential guide rail and slides along the circumference of the annular housing.

[0008] In some embodiments, the circumferential sliding seat of the fixing member is provided with a radial guide rail on the side surface away from the annular shell, and the extension direction of the radial guide rail is parallel to the diameter direction of the annular shell; the bottom of the fixing clamp is provided with a radial groove that matches the radial guide rail of the circumferential sliding seat, and the fixing clamp is engaged with the circumferential sliding seat through the radial groove and slides radially along the annular shell.

[0009] In some embodiments, the radial guide rails on the circumferential sliding seat are double guide rails, including two parallel radial sub-guide rails; each radial sub-guide rail includes a guide portion perpendicular to the surface of the circumferential sliding seat and a locking portion extending vertically from the top of the guide portion away from the central axis of the circumferential sliding seat; the fixing clamp is provided with two radial sliding grooves, each radial sliding groove being adapted to one radial sub-guide rail. The cross-sections of the two radial sub-guide rails in this structure are two back-to-back inverted "L" shapes, the guide portion is used to guide the fixing clamp to slide radially, and the locking portion is used to engage the fixing clamp to prevent it from falling out of the radial guide rails.

[0010] In some embodiments, the radial guide rail on the circumferential slide seat is a single guide rail, including a guide portion perpendicular to the surface of the circumferential slide seat, and engaging portions extending vertically to both sides from the top of the guide portion. In this embodiment, the radial guide rail has a T-shaped cross-section.

[0011] In some embodiments, each end of the radial guide rail is provided with a limiting protrusion, which is located between the two radial sub-guide rails and perpendicularly connected to both radial sub-guide rails. The limiting protrusion prevents the fixing clamp from sliding off the radial guide rail from both ends. This structure is the limiting protrusion structure in this embodiment when the radial guide rail is a double guide rail.

[0012] In some embodiments, limiting protrusions are provided at both ends of the radial guide rail, and the limiting protrusions extend perpendicularly from the radial guide rail to both sides of the radial guide rail. This structure is the structure of the limiting protrusions in this embodiment when the radial guide rail is a single guide rail.

[0013] In some embodiments, the radial guide rail has anti-slip protrusions on the surface that contacts the radial groove, and / or the radial groove has anti-slip protrusions on the surface that contacts the radial guide rail. These anti-slip protrusions prevent the clamp from sliding too freely while ensuring radial sliding, thus preventing an appearance of instability in the clamp's fixation.

[0014] In addition, the present invention also provides a fan, including a fan cover, the fan cover including a plurality of circumferential frames arranged in concentric circles and a plurality of radial frames radiating radially from the center, and the aforementioned spray device is detachably mounted on the fan cover.

[0015] In some embodiments, the top of the fixing clamp is provided with at least two clamping arms, and a skeleton slot is formed between two adjacent clamping arms. The skeleton slot can detachably engage the radial skeleton or circumferential skeleton of the fan cover.

[0016] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0025] The applicant observed that when the spray device 1 cannot be adapted to various fans, it is usually because the position of the fixing clip of the spray device 1 is incompatible with the position of the fan shroud frame. When the fixing clip of the spray device 1 is fixed to the radial frame 202 of the fan shroud 2, it may not be able to engage with the radial frame because the fixing clip is located exactly around one circumferential frame 202. When the fixing clip is set to be fixed to the circumferential frame 201 of the fan rib, it may not be able to engage with the fan shroud 1 because it is located exactly between two circumferential frames 201. Analysis shows that the reason for the above incompatibility is that the fixing clip of the spray device 1 cannot be radially adjusted. Therefore, this utility model provides a novel spray device whose fixing clip can be radially adjusted to adapt to more different fan shrouds.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 2 As shown, the spray device of Embodiment 1 of this utility model includes an annular outer shell 10, an annular spray pipe 21 disposed inside the annular outer shell 10, an input pipe 22 for supplying water to the spray pipe 21, and a fixing member 40 disposed on the annular outer shell 10 and capable of fixing the annular outer shell 10 to the fan shroud. The fixing member 40 can be adjusted circumferentially or radially.

[0029] Specifically, the annular outer shell 10 includes a first cover plate 11 and a second cover plate 12. Both the first cover plate 11 and the second cover plate 12 are semi-enclosed structures and are annular. The second cover plate 12 is fixed to the opening of the first cover plate 11 by screws, and the two are fastened together to form an internally hollow annular shell. The spray pipe 21 is fixed within the semi-enclosed space of the first cover plate 11, that is, fixed inside the annular outer shell 10.

[0030] The first cover plate 11 is located on the side of the annular outer shell 10 away from the fan shroud. A plurality of through holes are evenly spaced circumferentially on its panel facing away from the fan shroud. A plurality of nozzles 30 are circumferentially spaced on the annular spray pipe 21, each nozzle 30 corresponding to a through hole in the first cover plate 11, allowing water in the spray pipe 21 to be sprayed to the outside through the nozzle 30. Preferably, the nozzles 30 are fixed to the spray pipe 21 by a T-joint connector, and the nozzles 30 and the T-joint are detachably connected by threads. Each nozzle 30 protrudes from the first cover plate 11, facilitating quick and convenient replacement of nozzles 30 with different spray specifications.

[0031] The outer sidewall of the first cover plate 11 has a notch. The input pipe 22 is connected to the spray pipe 21 inside the annular shell 10 at the notch via a quick-connect tee connector, allowing water to be introduced into the spray pipe 21. One end of the input pipe 22 is the water inlet end of the spray pipe 21, and a valve is provided on the water inlet end to control the flow of water. Preferably, the outer sidewall of the first cover plate 11 extends outward at the notch, so that the tee connector between the input pipe 22 and the spray pipe 21 is covered and protected by the first cover plate 11.

[0032] The second cover plate 12 is located on the side of the annular outer shell 10 facing the fan shroud. The two sides of its panel facing the fan shroud protrude from the inner and outer annular sidewalls of the second cover plate 12, forming a circumferential guide rail 121. The fixing member 40 is slidably connected to the circumferential guide rail 121 and can slide along the circumference of the annular outer shell 10. Specifically, the fixing member 40 includes a circumferential sliding seat 41 and a fixing clip 42 detachably and slidably connected to the circumferential sliding seat 41. The circumferential sliding seat 41 is C-shaped, with both ends of the C-shape inwardly forming circumferential sliding grooves 411, which engage with the circumferential guide rail 121 on the second cover plate 12 of the annular outer shell 10, so that the circumferential sliding seat 41 is engaged on the annular outer shell 10 and can slide along the circumferential guide rail 121.

[0033] A radial guide rail 412 is provided on the surface of the circumferential sliding seat 41 away from the annular outer shell 10. The extending direction of the radial guide rail 412 is parallel to the radial direction of the annular outer shell 10. In this embodiment, the radial guide rail 412 is a double guide rail, that is, the radial guide rail 412 includes two mutually parallel radial sub-guide rails. Each radial sub-guide rail includes a guide portion 412a and an engaging portion 412b. The guide portion 412a is perpendicular to the surface of the circumferential sliding seat 41 away from the annular outer shell 10. The engaging portion 412b extends from the top of the guide portion 412a in a direction away from the central axis of the circumferential sliding seat 41 and is perpendicular to the guide portion 412a, for engaging with the fixing clamp 42. In this way, the cross-section of the two radial sub-guide rails is an inverted "L" shape facing away from each other. Furthermore, the radial guide rail 412 is provided with limiting protrusions 413 at both ends. The limiting protrusions 413 are located between the two radial sub-guide rails and are perpendicularly connected to the two radial sub-guide rails to prevent the fixing clamp 42 from sliding out from both ends of the radial guide rail 412.

[0034] The bottom surface of the fixing clamp 42 facing the annular outer shell 10 has two radial grooves that mate with the radial guide rails 412. Each radial groove includes a guide groove and a locking groove. The guide groove extends vertically inward from the bottom surface of the fixing clamp 42 and mates with the guide portion 412a of the radial guide rail 412. The locking groove extends vertically from the top of the guide groove in a direction away from the central axis of the fixing clamp 42 and mates with the locking portion 412b of the radial guide rail 412. The top of the fixing clamp 42 has three clamping arms 421 spaced circumferentially along the annular outer shell 10. A skeleton locking groove is formed between two adjacent clamping arms 421, allowing it to be locked onto the radial skeleton of the fan shroud. Preferably, the fixing clip 42 is made of elastic rubber material, the clamping arm 421 is thickest at the top and the top is arc-shaped, so the width of the opening of the frame slot is smaller than the width at the bottom. When the fan shroud frame enters the frame slot, it first pushes the tops of the two adjacent clamping arms 421 to the sides, passes through the opening and enters the frame slot to be clamped, and at the same time the opening returns to its original width for limiting.

[0035] Furthermore, the radial guide rail 412 has anti-slip protrusions (not shown in the figure) on the contact surface with the radial slide groove, and / or the surface of the radial slide groove that contacts the radial guide rail 412. Specifically, these can be rubber protrusions or strips, which increases the sliding resistance of the fixing clamp 42 on the circumferential sliding seat 41 while maintaining the radial sliding capability, so that it does not slide too freely and prevents the fixing clamp from appearing unstable.

[0036] In some alternative embodiments, the top of the retaining clip 42 may have only two clamping arms 421 to accommodate fan shrouds with sparser radial skeletons. In contrast, the retaining clip 42 with three clamping arms 421 is more suitable for fan shrouds with denser radial skeletons. Alternatively, the clamping arms 421 of the retaining clip 42 may be arranged radially spaced along the annular housing 10, forming a skeleton slot that can be used to snap onto the circumferential skeleton of the fan shroud. In a spray device product, there may be retaining clips 42 with three clamping arms 421 and retaining clips 42 with two clamping arms 421 for clamping onto the radial skeleton, and retaining clips 42 with three clamping arms 421 and retaining clips 42 with two clamping arms 421 for clamping onto the circumferential skeleton. The user can select the appropriate retaining clip 42 to install onto the radial guide rail 412 of the circumferential sliding seat 41 according to the actual situation.

[0037] In this way, the position of the fixing member 40 can be adjusted circumferentially via the circumferential sliding seat 41, and the radial position of the fixing clip 42 of the fixing member 40 can also be adjusted. After being adjusted to a suitable position, the spraying device can be installed on the fan shroud via the fixing member 40. Open the valve at the water inlet end of the input pipe 22 to allow water to flow in. The water flows into the spray pipe 21 and sprays water mist outward through the nozzle 30. Combined with the fan's airflow, a cooling effect can be achieved. When changing to a different fixing clip 42, first remove the spraying device from the fan shroud. Pinch the two clamping arms 421 of the fixing clip 42 towards the middle. The radial groove will also deform under the deformation of the clamping arms 421, and the inner space of the radial groove will increase. Then the fixing clip 42 can be removed from the radial guide rail 412 of the circumferential sliding seat 41. Alternatively, you can directly pry the bottom of the fixing clip 42 with your fingers to disengage the radial groove from the radial guide rail 412 on the circumferential sliding seat 41. Conversely, when installing the retaining clip 42, its elasticity is also used to slightly deform it so that it engages with the radial guide rail 412 of the circumferential sliding seat 41.

[0038] Compared to existing technologies, the fixing member 40 of this invention can be adjusted both circumferentially and radially, allowing for the use of different fan covers. Furthermore, the fixing clip 42 can be detached from the circumferential sliding seat 41 and replaced with various styles of fixing clips 42, further enabling it to adapt to different fan covers.

[0039] Example 2

[0040] The structure of the fan spray device in Embodiment 2 of this utility model is basically the same as that in Embodiment 1, the only difference being:

[0041] The fixing clip 42 of the fixing member 40 is provided with two clamping arms 421', which can be clamped onto the radial frame of the fan shroud. The radial guide rail 412' on the surface of the circumferential sliding seat 41 of the fixing member 40 is a single guide rail. The cross-section of the radial guide rail 412' is "T"-shaped, including a guide portion 412a' and an engaging portion 412b'. The guide portion 412a' is perpendicular to the surface of the circumferential sliding seat 41 away from the annular outer shell 10. The engaging portion 412b' extends from the top of the guide portion 412a' to both sides away from the central axis of the circumferential sliding seat 41 and is perpendicular to the guide portion 412a', for engaging with the fixing clip 42. Correspondingly, the bottom surface of the fixing clip 42 is provided with a groove that matches the "T"-shaped radial guide rail 412'. The fixing clip 42 is engaged with the radial guide rail 412' of the circumferential sliding seat 41 through the groove and slides along the radial guide rail 412'.

[0042] The radial guide rail 412 has limiting protrusions 413 at both ends, which extend vertically from the radial guide rail 412' to both sides of the radial guide rail 412. This prevents the fixing clip 42 from sliding off the ends of the radial guide rail 412'. The contact surfaces of the radial guide rail 412' and the radial groove, and / or the contact surfaces of the radial groove and the radial guide rail 412', are provided with anti-slip protrusions, specifically rubber protrusions, to prevent the fixing clip 42 from sliding too freely on the circumferential sliding seat 41.

[0043] When the retaining clip 42 needs to be replaced, the tops of the two clamping arms 421' on both sides of the retaining clip 42 are pinched towards the middle. The radial groove deforms under the deformation of the clamping arms 421', increasing the space inside the radial groove, allowing the retaining clip 42 to be removed from the radial guide rail 412 of the circumferential sliding seat 41. Alternatively, the bottom of the retaining clip 42 can be pried open with a finger to deform the radial groove and disengage it from the radial guide rail 412 of the circumferential sliding seat 41. Conversely, when installing the retaining clip 42, its elasticity is used to slightly deform the retaining clip 42 to engage it with the radial guide rail 412 of the circumferential sliding seat 41.
