Abstract
Description
Technical Field
[0001] This utility model relates to the field of fountain-related technology, and in particular to a fountain device. Background Technology
[0002] With the rapid development of musical fountain technology, its application scenarios have covered various places such as squares, commercial centers, villa courtyards, and residential communities. Currently, existing fountain devices adjust the relative position between the baffle plate and the nozzle through the extension and retraction of the tie rod shaft, thereby changing the water pattern of the nozzle.
[0003] To ensure the stability of the tie rod shaft's extension and retraction, fountain devices typically require the installation of bushings within the housing to guide the shaft's movement. However, the installation of bushings increases the housing's height, leading to a larger overall size of the fountain device. This makes it difficult for the fountain to adapt to on-site conditions with limited water levels and confined spaces, thus restricting its application range. Utility Model Content
[0004] In view of this, it is necessary to provide a fountain device with a smaller overall size.
[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0006] A fountain device, comprising:
[0007] Box;
[0008] The water outlet mechanism includes a water outlet cylinder, a pull rod shaft, and a baffle plate. The pull rod shaft is telescopically mounted on the housing, and the baffle plate is mounted on the pull rod shaft at the end away from the housing, for controlling the water outlet pattern of the water outlet cylinder.
[0009] A bushing is housed within the water outlet cylinder and connected to the housing. The bushing is also fitted onto the pull rod shaft and slidably connected to the pull rod shaft, serving to guide the pull rod shaft in its telescopic movement relative to the housing.
[0010] A transmission mechanism, housed within the housing and connected to the pull rod shaft, is used to drive the pull rod shaft to perform telescopic movement relative to the housing.
[0011] A rotary drive mechanism is connected to the transmission mechanism and is used to provide a power source for the transmission mechanism.
[0012] Understandably, using a bushing installed outside the housing to guide the extension and retraction of the tie rod shaft avoids designing the bushing inside the housing. This reduces the height dimension of the housing, thereby miniaturizing the overall size of the fountain device and making it suitable for applications in situations with limited water level and confined space.
[0013] In one embodiment, the water outlet cylinder includes a three-way connector and a nozzle. The three-way connector is disposed on the housing and connected and sealed to the housing. The nozzle is disposed on the end of the three-way connector away from the housing and connected and sealed to the three-way connector.
[0014] The bushing is housed within the tee connector; and a guide vane is installed inside the nozzle, allowing the medium introduced through the tee connector to flow towards the baffle plate via the guide vane.
[0015] It is understandable that the guide vane is used to guide the medium passing through the bushing, thus avoiding any impact of the bushing design on the final water outlet pattern.
[0016] In one embodiment, the guide vane is fitted onto the pull rod shaft, and a cavity is formed between the guide vane and the pull rod shaft;
[0017] The guide vane abuts against the inner peripheral wall of the nozzle and is connected to the nozzle.
[0018] In one embodiment, the transmission mechanism includes a pull rod, a first cam, and a second cam. The first cam and the second cam are disposed on opposite sides of the pull rod and are respectively connected to one end of the pull rod in a transmission manner; the other end of the pull rod is connected to the pull rod shaft in a hinged manner.
[0019] The first cam is connected to the rotary drive mechanism, and the second cam is rotatably connected to the housing.
[0020] In one embodiment, the transmission mechanism further includes a connecting rod pin, which passes through the first cam, the pull rod, and the second cam in sequence, and the two ends of the connecting rod pin extending out of the first cam and the second cam are respectively limited by locking nuts;
[0021] The pull rod is fitted with a bearing, and the pull rod can be rotatably mounted on the connecting rod pin via the bearing; and the bearing is respectively abutted and limited by retaining rings fitted on the connecting rod pin.
[0022] In one embodiment, the second cam has a first rotational central shaft that is rotatably mounted on the housing via a self-aligning bearing.
[0023] It is understandable that self-aligning bearings are used to support the second cam on the housing. This ensures the smooth operation of the second cam and prevents jamming, thereby increasing the service life of the fountain device.
[0024] In one embodiment, the housing is fitted with a bearing seat by a plug-in connection, and the portion of the bearing seat located on the outside of the housing is connected to the housing by a connector.
[0025] The self-aligning bearing is installed on the bearing housing within the housing.
[0026] Understandably, the housing uses a bearing housing to support the self-aligning bearing, which facilitates the assembly of the second cam on the housing.
[0027] In one embodiment, the rotary drive mechanism includes a rotary motor, a worm, a worm wheel, and a worm wheel shaft, wherein the worm meshes with the worm wheel and is drively connected to the rotary motor;
[0028] The worm gear shaft passes through the worm gear and engages with the worm gear keyway, wherein a portion of the worm gear shaft extends into the housing and is connected to the transmission mechanism for transmission.
[0029] In one embodiment, a trigger is mounted on one end of the worm gear shaft away from the transmission mechanism, and the trigger can rotate with the worm gear shaft and change the position of the trigger;
[0030] The fountain device also includes a detection sensor, which can be triggered by the triggering element to generate a feedback signal.
[0031] It is understandable that placing the detection sensor on the outside of the housing facilitates its installation and ensures good consistency in speed adjustment and zeroing.
[0032] In one embodiment, the rotary motor is at least partially located within the area along the height of the water outlet cylinder.
[0033] Due to the application of the above solution, this application has the following advantages compared with the prior art:
[0034] The fountain device for which this application seeks protection uses a bushing mounted outside the housing to guide the extension and retraction of the tie rod shaft. This avoids designing the bushing inside the housing, thereby reducing the height dimension of the housing and achieving a miniaturization of the overall size of the fountain device. This makes the fountain device suitable for use in field conditions where the water level is high and the space is narrow. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0047] like Figures 1 to 5As shown, the fountain device 100 claimed in this application includes a housing 10, a water outlet mechanism, a bushing 30, a transmission mechanism, and a rotary drive mechanism. The water outlet mechanism includes a water outlet cylinder 21, a pull rod shaft 22, and a baffle plate 23. The pull rod shaft 22 is telescopically mounted on the housing 10, and the baffle plate 23 is mounted on the pull rod shaft 22 at the end away from the housing 10, for controlling the water pattern of the water outlet cylinder 21. The bushing 30 is housed in the water outlet cylinder 21 and connected to the housing 10. The bushing 30 is fitted onto the pull rod shaft 22 and slidably connected to the pull rod shaft 22, for guiding the telescopic movement of the pull rod shaft 22 relative to the housing 10. The transmission mechanism is housed in the housing 10 and is drive-connected to the pull rod shaft 22, for driving the pull rod shaft 22 to telescopically move relative to the housing 10. The rotary drive mechanism is drive-connected to the transmission mechanism, for providing a power source to the transmission mechanism.
[0048] As can be seen from the above, the bushing 30 installed outside the housing 10 guides the extension and retraction of the tie rod shaft 22. This avoids designing the bushing 30 inside the housing 10, thereby reducing the height dimension of the housing 10 and achieving the miniaturization of the overall size of the fountain device 100. This makes the fountain device 100 suitable for application in field conditions where the water level is limited and the space is narrow.
[0049] like Figure 2 , Figure 3 As shown, in one embodiment, the water outlet cylinder 21 includes a three-way connector 211 and a nozzle 212. The three-way connector 211 is disposed on the housing 10 and connected and sealed to the housing 10. The nozzle 212 is disposed on the end of the three-way connector 211 away from the housing 10 and connected and sealed to the three-way connector 211. A bushing 30 is housed within the three-way connector 211. Furthermore, a guide vane 24 is installed inside the nozzle 212, and the medium introduced through the three-way connector 211 can flow through the guide vane 24 to the baffle plate 23. That is, the guide vane 24 guides the medium passing through the bushing 30, thus preventing the bushing 30 within the three-way connector 211 from affecting the final water outlet pattern. Here, the three-way connector 211 has a water inlet end 2111, which is connected and communicates with an external water pipe (not shown).
[0050] like Figure 2 , Figure 5 As shown, in one embodiment, the guide vane 24 is fitted onto the pull rod shaft 22, and a cavity 201 is formed between the guide vane 24 and the pull rod shaft 22; the guide vane 24 abuts against the inner peripheral wall of the nozzle 212 and is connected to the nozzle 212.
[0051] In this embodiment, a gap 202 is formed between the baffle plate 23 and the inner peripheral wall of the nozzle 212. The medium introduced by the tee connector 211 can be sprayed outward through the cavity 201 and the gap 202 in sequence. During this process, the bottom inclined surface 231 of the baffle plate 23 can be used to block the water sprayed through the gap 202, thereby creating a water pattern. When the baffle plate 23 moves in a telescoping motion relative to the nozzle 212 along the axial direction, the size of the gap 202 between the baffle plate 23 and the nozzle 212 changes accordingly, thereby adjusting the water flow through the gap 202 and ultimately changing the water pattern of the nozzle 212.
[0052] like Figure 2 , Figure 5 As shown, in one embodiment, the transmission mechanism includes a pull rod 41, a first cam 42 and a second cam 43. The first cam 42 and the second cam 43 are disposed on two opposite sides of the pull rod 41 and are respectively connected to one end of the pull rod 41 in a transmission manner. The other end of the pull rod 41 is connected to the pull rod shaft 22 in a hinged manner. The first cam 42 is connected to the rotary drive mechanism in a transmission manner, and the second cam 43 is rotatably connected to the housing 10.
[0053] like Figure 2 , Figure 5 As shown, in one embodiment, the transmission mechanism further includes a connecting rod pin 44, which passes through the first cam 42, the pull rod 41, and the second cam 43 in sequence. The two ends of the connecting rod pin 44 that extend out of the first cam 42 and the second cam 43 are respectively limited by locking nuts 45. The pull rod 41 is fitted with a bearing 46, and the pull rod 41 is rotatably mounted on the connecting rod pin 44 through the bearing 46. The bearing 46 and the first cam 42 and the second cam 43 are respectively abutted and limited by retaining rings 47 fitted on the connecting rod pin 44.
[0054] like Figure 2 , Figure 5 As shown, in one embodiment, the second cam 43 has a first rotational central shaft 431, which can be rotatably mounted on the housing 10 via a self-aligning bearing 48. That is, the self-aligning bearing 48 is used to support the second cam 43 on the housing 10, thus ensuring the smooth operation of the second cam 43 without jamming, thereby increasing the service life of the fountain device 100.
[0055] like Figure 2 , Figure 3As shown, in one embodiment, the housing 10 is fitted with a bearing seat 49 via a plug-in connection, and the portion of the bearing seat 49 located on the outside of the housing 10 is connected to the housing 10 via a connector 491; the self-aligning bearing 48 is mounted on the portion of the bearing seat 49 located inside the housing 10. That is, the housing 10 uses the bearing seat 49 to support the self-aligning bearing 48, thus facilitating the assembly of the second cam 43 onto the housing 10. In this embodiment, the connector 491 passes through the bearing seat 49 and is screwed to the housing 10, thereby achieving the assembly connection between the bearing seat 49 and the housing 10. Here, the connector 491 can be a screw, bolt, etc.
[0056] like Figure 5 As shown, in one embodiment, the rotary drive mechanism includes a rotary motor 51, a worm 52, a worm wheel 53, and a worm wheel shaft 54. The worm 52 meshes with the worm wheel 53 and is drive-connected to the rotary motor 51. The worm wheel shaft 54 passes through the worm wheel 53 and engages with the keyway 541 of the worm wheel 53. A portion of the worm wheel shaft 54 extends into the housing 10 and is drive-connected to the transmission mechanism. In this embodiment, the worm wheel shaft 54 extends into the housing 10 and is drive-connected to the second rotation center shaft 421 of the first cam 42 via a coupling 55. Thus, when the rotary motor 51 drives the worm wheel 53 to rotate via the worm 52, it can also drive the first cam 42 to rotate via the coupling 55.
[0057] like Figure 4 As shown, in one embodiment, a trigger 60 is mounted on the end of the worm gear shaft 54 away from the transmission mechanism, and the trigger 60 can rotate with the worm gear shaft 54 and change its position. The fountain device 100 also includes a detection sensor 70, which can be triggered by the trigger 60 to generate a feedback signal. That is, the detection sensor 70 is positioned on the outside of the housing 10, which facilitates its installation and ensures good consistency in speed regulation and zeroing.
[0058] like Figure 4 , Figure 5 As shown, in this embodiment, the fountain device 100 also includes a housing 80, and a rotary drive mechanism is installed in the housing 80 and disposed on one side of the housing 10; wherein, the worm 52 and the worm wheel 53 are disposed inside the housing 80, the worm wheel shaft 54 passes through the housing 80, and the end portion of the worm wheel shaft 54 away from the first cam 42 extends out of the housing 80.
[0059] In this embodiment, the detection sensor 70 is fixedly mounted outside the housing 80 via a fixing plate 90; the trigger 60 includes a sensing base 61 and a sensing screw 62. The sensing base 61 is fitted onto the portion of the worm gear shaft 54 that extends outside the housing 80, and the sensing screw 62 is mounted on the sensing base 61 and positioned directly opposite the detection sensor 70, so that the sensing base 61 can rotate relative to the housing 80 along with the worm gear shaft 54 and be detected by the detection sensor 70. It should be noted that the detection sensor 70 described above can be a proximity switch, photoelectric switch, etc.
[0060] like Figure 3 As shown, in one embodiment, the rotary motor 51 is at least partially disposed in the region along the height direction of the water outlet cylinder 21.
[0061] When the fountain device 100 of this application is working, when the rotary motor 51 drives the worm wheel 53 to rotate through the worm 52, the worm wheel 53 drives the worm wheel shaft 54 to rotate. At the same time, the first cam 42 is driven to rotate through the coupling 55. The connecting rod pin 44 locks and limits the two ends of the first cam 42 and the second cam 43, so that the second cam 43 rotates synchronously with the first cam 42. During this process, the pull rod 41 reciprocates along the axial direction of the pull rod shaft 22 under the drive of the first cam 42 and the second cam 43, thereby driving the pull rod shaft 22 to perform telescopic movement relative to the housing 10.
[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
