Description

Technical Field

[0001] This invention relates to the field of bathroom product testing technology, and specifically discloses an online testing device for the water output effect of a shower head. Background Technology

[0002] The shower head is a core component of shower equipment, and its water output directly determines the user experience. After assembly and before leaving the factory, shower heads must undergo water output testing to prevent substandard products with defects such as blockages or uneven water flow from entering the market.

[0003] Currently, there are several shower head water flow testing devices on the market. For example, utility model patent application number 202020082481.6 discloses a shower head testing device. This device mainly includes a base, a water storage box, a first support rod, a second support rod, a water pump, a water pump pipe, a water injection pipe, a fixing plate, a fixing clamp, and a testing device composed of a fixing frame, a carrying frame, a mounting plate, multiple sliders, multiple fixing sleeves, and multiple water receiving cylinders. In use, the shower head is first clamped and fixed by the fixing clamp. Then, the water injection pipe is manually screwed onto the threaded sleeve of the shower head handle. Finally, the water pump pumps water from the water storage box into the shower head through the water injection pipe. The shower head sprays water downwards, and the multiple water receiving cylinders in the carrying frame collect the water flow from different areas, thereby determining whether the water flow is uniform in each area.

[0004] However, the aforementioned existing technology has the following three shortcomings in practical use. First, the water injection pipe and the shower head inlet end in this testing device use a traditional threaded connection. For each shower head tested, the operator needs to manually screw the water injection pipe onto the shower head handle, and then manually loosen and disassemble it after the test. This repetitive manual operation is time-consuming and labor-intensive. In production scenarios where a large number of shower heads need to be tested one by one, the disassembly and assembly of the water injection pipe and the shower head becomes a bottleneck in the entire testing process, preventing the device from being integrated into an automated production line and making it difficult to achieve high-efficiency online testing. Second, the water injection pipe and the shower head inlet end rely on the pressure of the threaded end face to achieve a seal. The sealing effect is highly dependent on the tightening force of the operator each time. If the connection is too loose, leakage may occur at the threaded connection under water pressure, causing the actual water flow and pressure entering the shower head to be lower than the set value, thus affecting the accuracy of the water output test. Thirdly, most showerheads on the market currently have multiple water flow settings, each corresponding to a different water flow pattern. During factory testing, the water flow effect of each setting needs to be verified separately. However, the existing devices can only test the water flow of a single showerhead setting. When testing other water flow settings, the operator must manually operate the shift lever or knob on the showerhead, making it impossible to complete the comprehensive testing of all water flow modes of a multi-setting showerhead in a single setup. Therefore, this application proposes a newly designed online showerhead water flow effect testing device to address the technical problems and shortcomings of existing testing devices in terms of automation, testing efficiency, sealing reliability, and multi-setting testing capability. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing shower head testing devices and provide a rotary online shower head water output effect testing device. This device can achieve automatic docking and sealing between the water supply pipeline and the shower head inlet, eliminating the need for manual screwing and disassembly. At the same time, it can automatically complete the continuous testing of various water output modes of multiple shower heads in a single clamping, thereby significantly improving the automation level, testing efficiency and testing accuracy of shower head water output effect testing.

[0006] This invention is achieved through the following technical solution: An online shower head water output performance testing device includes a base assembly, a shower head carrier rotor, a water injection mechanism, a water receiving mechanism, and a testing unit. Wherein: The stand assembly has a shower carrier rotor that is driven by a power unit to rotate intermittently on it. The shower carrier rotor has multiple stations evenly arranged around its circumference for positioning the shower head. The water injection mechanism is located below the shower carrier rotor and is used to supply test water to the shower head located at the water outlet test station. A water receiving mechanism is located around the shower carrier rotor and corresponds to the water outlet detection station, used to collect the test water sprayed from the shower head; The detection unit is located above the water receiving mechanism and is used to visually detect and judge the water output effect of the shower head. The upper and lower ends of the support assembly are respectively provided with roller pressing lifting ring and push ring groove; The lower end of the rotor of the shower carrier is provided with a handle insertion stepped hole for inserting the shower handle at each station. Above each handle insertion stepped hole is a liftable shower head positioning block. The shower head positioning block cooperates with the roller pressing lifting ring through the first guide component to press the shower head down at the water outlet detection station and release the shower head at the loading and unloading station. The water injection mechanism is equipped with a liftable sealing plug for each station. The sealing plug is connected to the water injection mechanism through a pipe assembly. The sealing plug rises at the water outlet detection station and seals with the lower end of the shower handle through the second guide assembly, and falls down at the loading and unloading station to separate from the shower handle.

[0007] As a further provision of the above solution, the support assembly includes a water collection tray base, a cylindrical body is fixedly disposed at the center of the water collection tray base, and the push-ring groove is opened on the outer circular surface of the cylindrical body; a column extending upward and used for rotatably installing the shower carrier rotor is concentrically fixed inside the cylindrical body, a top plate is installed on the top of the column, and the roller pressing lifting ring is concentrically disposed on the lower surface of the top plate.

[0008] As a further feature of the above scheme, the top-pushing ring groove includes a lower arc groove, an upper arc groove, and a transition connecting groove connecting the lower arc groove and the upper arc groove; the roller pressing lifting ring includes an upper ring section, a lower ring section, and a transition connecting section connecting the upper ring section and the lower ring section; the lower arc groove is aligned with the upper ring section and corresponds to the loading and unloading station, and the upper arc groove is aligned with the lower ring section and corresponds to the water outlet detection station.

[0009] As a further feature of the above scheme, the shower carrier rotor includes a rotor body, with an upper disc and a lower disc respectively provided at the upper and lower ends of the rotor body; a plurality of the handle insertion stepped holes are evenly opened circumferentially on the outer edge of the lower disc, and the upper disc is provided with guide holes aligned vertically with each handle insertion stepped hole. The first guide assembly includes a guide rod that is vertically inserted through a guide hole. The top end of the guide rod is provided with a first roller that acts to press against the lifting ring with a roller. The lower end of the guide rod is connected to the shower head positioning block, and a spring is connected between the shower head positioning block and the upper disc.

[0010] As a further provision of the above scheme, the water injection mechanism includes a sealing ring sleeve that is rotatably and sealingly connected to the lower end of the outer circular surface of the column, and multiple sealing plugs are connected to the sealing ring sleeve through a pipe assembly; a water storage cavity is opened inside the lower end of the column, and a connecting hole that communicates with the inside of the sealing ring sleeve is opened at the upper end of the water storage cavity. The water injection mechanism also includes a water tank and a water pump connected to the water tank, and the water storage chamber and the water pump are connected by a water supply pipe.

[0011] As a further provision of the above scheme, the pipeline assembly includes a radial water pipe connected to the sealing ring sleeve, and a solenoid valve is provided on the radial water pipe. The end of the radial water pipe is connected to a vertically arranged telescopic pipe, and the upper end of the telescopic pipe is connected to a connector pipe. The sealing plug is located at the top of the connector pipe and directly below the handle insertion stepped hole of the corresponding work position.

[0012] As a further feature of the above solution, the sealing plug includes a head with a frustum-shaped top, and an end ring with a diameter larger than the outer diameter of the threaded sleeve at the lower end of the shower handle is provided below the head. The upper surface of the end ring is provided with a rubber sealing ring.

[0013] As a further provision of the above scheme, the lower surface of the lower disc is uniformly fixed with L-shaped connecting strips corresponding to each of the radial water pipes. The second guide assembly includes a pusher bar vertically inserted into the L-shaped connecting strip. The upper end of the pusher bar is fixedly connected to the sealing plug, and the lower end of the pusher bar is provided with a second roller that interacts with the pusher ring groove. A vertical groove is opened on the pusher bar, and a slider fixedly connected to the radial water pipe is slidably arranged in the vertical groove.

[0014] As a further provision of the above scheme, the detection unit includes a CCD camera mounted on the water receiving mechanism. The CCD camera is positioned to target the shower head at the water outlet detection station and is used to continuously capture images of the shower head's water outlet process. The CCD camera is electrically connected to a host computer, which analyzes and processes the captured images to determine whether the shower head's water outlet effect is qualified.

[0015] As a further feature of the above scheme, at least two CCD cameras are provided, and a shift adjustment mechanism is provided on the water receiving mechanism between the two CCD cameras. The shift adjustment mechanism automatically switches the water output level of the shower head during the detection process. The shift adjustment mechanism includes a splined hollow cylinder that is rotatably mounted on the water receiving mechanism in a radial direction, and a rotary transmission assembly for driving the splined hollow cylinder to rotate. A splined shaft is inserted into the inner end of the splined hollow cylinder, and a toggle part is provided at the inner end of the splined shaft. A telescopic drive is fixedly installed at the outer end of the splined hollow cylinder, and the telescopic end of the telescopic drive is connected to the splined shaft.

[0016] The core technology of the online shower head water output effect detection device disclosed in this invention lies in the use of rollers set at the upper and lower ends of the base assembly to press against the lifting ring and the pushing ring groove, thereby synchronously converting the rotational motion of the shower head carrier rotor into the clamping / releasing action of the shower head and the docking / disconnecting action of the water supply pipeline, thus realizing a purely mechanical linkage automated detection process.

[0017] Specifically, as the shower head carrier rotor carries the shower head under test from the loading / unloading station to the water outlet testing station, the first roller on the shower head positioning block gradually enters the lower ring section along the transition connection section of the roller pressing and lifting ring, driving the shower head positioning block to slide downwards and press the shower head from above. Simultaneously, the second roller at the lower end of the push bar in the water injection mechanism climbs from the lower arc groove to the upper arc groove along the transition connection groove of the push ring groove, driving the sealing plug to rise and insert into the threaded sleeve at the lower end of the shower head handle, completing automatic centering and end-face sealing. When the shower head reaches the water outlet testing station, it has been reliably pressed, and the water supply pipeline has been sealed and connected. At this time, the solenoid valve opens, the shower head sprays water, and the testing unit performs visual inspection. After the inspection is completed, the shower head carrier rotor continues to rotate. During the return to the loading / unloading station, the two sets of rollers reset along their respective tracks, the shower head positioning block rises and releases, and the sealing plug descends and disengages, achieving fully automatic reset.

[0018] In addition, for shower heads with multiple water output functions, the present invention also provides a shift adjustment mechanism between two adjacent testing stations. Through a radially extendable spline shaft and a rotating actuating part, the shift paddle of the shower head is automatically actuated during the testing process to achieve automatic switching of the gear, thereby completing continuous testing of all water output modes in one clamping.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The online shower head water flow effect testing device disclosed in this invention utilizes a linkage structure between the shower head positioning block and the roller pressing and lifting ring, and between the sealing plug and the pushing ring groove. This synchronously transforms the rotational motion of the shower head carrier rotor into the clamping / releasing action of the shower head and the docking / disconnecting action of the water supply pipeline, achieving full automation of water supply docking and disconnection. Throughout the testing process, the shower head only needs to be installed and removed once at the loading and unloading station. Subsequent actions such as clamping and fixing, sealing and docking, water flow testing, and loosening and resetting are all automatically driven during rotation, requiring no manual intervention. This design completely eliminates the repetitive labor of manually screwing and disassembling the water supply pipe for each shower head tested under traditional threaded connection methods. The testing cycle is significantly shortened, and the testing device can be seamlessly integrated into automated production lines, truly achieving continuous online testing and significantly improving batch testing efficiency.

[0020] The sealing plug in this invention automatically inserts into the threaded sleeve of the shower handle under the action of the push-ring groove. Simultaneously, through its unique structural design, during its ascent, the frustum-shaped head first extends into the threaded sleeve at the lower end of the shower handle for centering and guidance. Subsequently, the rubber sealing ring on the end ring adheres to the end face of the threaded sleeve with a constant clamping force, forming an end face seal. This sealing method is unaffected by human operation, ensuring consistent and reliable sealing force each time. It fundamentally eliminates the leakage problem caused by insufficient tightening force in traditional manual threaded connections, effectively preventing poor shower water output due to leakage at the connection point and greatly ensuring the accuracy of shower water output performance testing.

[0021] The testing device disclosed in this invention, for showerheads with multi-level water output functions, incorporates a shift adjustment mechanism between two adjacent testing stations. After the showerhead completes the first stage of water output testing, the showerhead carrier rotor moves it to the shift station, where the shift adjustment mechanism actuates the shift paddle to switch the water output level. After switching, the mechanism resets and disengages. During multi-level water output function testing of the showerhead, there is no need for reassembly; the device can continue rotating to the next testing station within the same testing process to test the water output effect of another level, achieving complete testing coverage of all water output modes of multi-level showerheads.

[0022] This invention also includes a water collection tray base and a water receiving arc groove. The water receiving arc groove is arranged around the shower carrier rotor and directly opposite the water outlet testing position. During the water flow testing process, all the test water sprayed by the shower falls into the water receiving arc groove and returns to the water tank for recycling via the return pipe. This water circulation system avoids water waste and can significantly reduce water costs in batch continuous testing scenarios, while keeping the testing site dry and clean.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-10 This application will be described in detail with reference to the embodiments. Example 1

[0027] Example 1 discloses an online detection device for the water output effect of a shower head, such as... Figure 1 and Figure 2 As shown, the main body of the device includes a stand assembly 10, on which a shower carrier rotor 20 for positioning the shower head is rotatably mounted. Below the shower carrier rotor 20, a water injection mechanism 30 for injecting water into the shower head 100 is provided. A water receiving mechanism 40 is provided around the shower carrier rotor 20 located at the water spraying position, and a detection unit 50 for visually inspecting the water output effect of the shower head is provided at the upper end of the water receiving mechanism 40.

[0028] like Figure 3 and Figure 4As shown, the support assembly 10 includes a water collection tray base 11. A cylindrical body 12 is fixedly installed at the center of the water collection tray base 11. A push-ring groove 121 is formed on the outer circumference of the cylindrical body 12. The push-ring groove 121 includes an upper arc groove, a lower arc groove, and a transition connecting groove for connecting the two ends of the upper and lower arc grooves. Inside the cylindrical body 12, a column 13 extending upward is concentrically fixed. A top plate 14 is installed on the top of the column 13, and a roller pressing lifting ring 15 is concentrically arranged on the lower surface of the top plate 14. The roller pressing lifting ring 15 includes an upper ring section, a lower ring section, and a transition connecting section connecting the two ends of the upper and lower ring sections. It should be noted that the push-ring groove 121 and the roller pressing lifting ring 15 independently control the movement of the water injection mechanism 30 and the shower head positioning pressure block 25, and the two form the following cooperative relationship in the working position. At the water outlet testing station, the upper arc groove of the push ring groove 121 lifts the water injection mechanism 30, achieving water supply connection; simultaneously, the roller presses down the lower ring section of the lifting ring 15, pressing down the shower head positioning block 25 to lock and fix the shower head. At the loading and unloading station, the lower arc groove of the push ring groove 121 lowers the water injection mechanism 30 to disengage; simultaneously, the roller presses down the upper ring section of the lifting ring 15, causing the shower head positioning block 25 to rise and loosen, facilitating the loading and unloading of the shower head.

[0029] like Figure 5 and Figure 6 As shown, the shower carrier rotor 20 includes a regular polygonal prism-shaped rotor body 21. The upper and lower ends of the rotor body 21 are respectively provided with an upper disc 22 and a lower disc 23 extending radially outward. Multiple guide holes 221 are evenly arranged circumferentially on the outer edge of the upper disc 22, and a handle insertion stepped hole 231 aligned vertically with each guide hole 221 is provided on the outer edge of the lower disc 23. Each set of vertically aligned guide holes 221 and handle insertion stepped holes 231 corresponds to one side of the rotor body 21, and a vertically arranged vertical slide rail 24 is fixed on this side. A shower head positioning block 25 is slidably connected to each vertical slide rail 24. The upper end of the shower head positioning block 25 is connected to a guide rod 26 that vertically penetrates the corresponding guide hole 221. The top of the guide rod 26 is equipped with a first roller 261 that acts to press against the lifting ring 15. Springs 27, with their upper and lower ends respectively connected to the upper disc 22 and the shower head positioning block 25, are also fitted onto the guide rod 26. Furthermore, through holes rotatably connected to the column 13 are opened at the center of the shower carrier rotor 20, the upper disc 22, and the lower disc 23. A convex ring 28 with a driven gear 29 on its outer surface extends from the upper end of the through hole. A power device for driving the shower carrier rotor 20 to perform intermittent rotational motion is provided on the upper surface of the top plate 14. This power device includes a power motor 16, and a drive gear 17 meshing with the driven gear 29 is provided at the lower end of the motor shaft of the power motor 16.

[0030] like Figure 4 , Figure 7 and Figure 8 As shown, the water injection mechanism 30 includes a sealing ring 31 rotatably connected to the lower end of the outer circumference of the column 13. Multiple radial water pipes 32 are evenly arranged circumferentially on the outer circumference of the sealing ring 31. Each radial water pipe 32 corresponds to one side of the rotor body 21, and a solenoid valve 33 for controlling water flow is installed on each radial water pipe 32. A vertically arranged telescopic pipe 34 is connected to the radial outer end of each radial water pipe 32. A connector pipe 35 is connected to the upper end of the telescopic pipe 34. A sealing plug 36 is located directly below the stepped hole 231 of the handle insertion at the upper end of the connector pipe 35. When the sealing plug 36 moves upward and is inserted into the threaded sleeve at the lower end of the shower head 100 handle, a sealed connection is achieved. Specifically, the sealing plug 36 includes a head 361 with a frustum-shaped top. An end ring 362 with a diameter larger than the outer diameter of the threaded sleeve is located at the lower end of the head 361. A rubber sealing ring 363 is then provided on the upper surface of the end ring 362.

[0031] L-shaped connecting strips 37, corresponding to each radial water pipe 32, are uniformly fixedly arranged circumferentially on the lower surface of the lower disc 23. A pusher strip 38 is vertically inserted into the L-shaped connecting strip 37. The upper end of the pusher strip 38 is fixedly connected to the connector pipe 35 or the sealing plug 36. A second roller 39 is rotatably arranged at the lower end of the pusher strip 38. The second roller 39 interacts with the pusher ring groove 121 on the outer circumference of the cylindrical body 12. In addition, a vertical slot 381 is opened on the pusher strip 38. A slider 382, ​​which is fixedly connected to the radial water pipe 32, is slidably arranged in the vertical slot 381.

[0032] The water injection mechanism 30 also includes a water tank 301, to which a water pump 302 is connected. A water storage chamber 131 is formed inside the lower end of the column 13, and a water supply pipe 303 is connected between the water storage chamber 131 and the water pump 302. In addition, a connecting hole 132 is formed at the upper end of the water storage chamber 131, which communicates with the inside of the sealing ring 31. Water in the water tank 301 enters the water storage chamber 131 under the action of the water pump 302 and the water supply pipe 303, then enters the sealing ring 31 through the connecting hole 132, and flows outward along the open radial water pipe 32.

[0033] like Figure 9 As shown, the water receiving mechanism 40 includes a water receiving arc groove 41 arranged in a ring around the shower carrier rotor 20 and corresponding to the water outlet detection station. The lower end of the water receiving arc groove 41 is stably supported on the ground by several legs 42. A return pipe 43 is also provided between the water receiving arc groove 41 and the top of the water tank 301, so that the spray water can return to the water tank 301 through the return pipe 43 for recycling, thereby reducing the amount of water used for testing.

[0034] Finally, the detection unit 50 includes a CCD camera positioned at the upper end of the water receiving arc groove 41. This CCD camera is designed to continuously capture images of the water flow pattern at the water outlet detection station. Furthermore, the CCD camera is electrically connected to a host computer (not shown in the figure). The host computer integrates a control module and a storage module for image processing and comparison. The images captured by the CCD camera are comprehensively evaluated by the control module to determine whether the water flow effect of the shower head is qualified. The detection results are then stored for later review by staff.

[0035] The online shower head water output effect detection device disclosed in Embodiment 1 has the following working process: Step 1: When the device is started, the shower head carrier rotor 20 rotates intermittently under the drive of the power motor 16. When an unloaded positioning station rotates to the loading / unloading station, the handle of the shower head 100 to be tested is inserted into the handle insertion stepped hole 231 by a person or an external robot, keeping the shower head facing outward. At this time, the station is in the loading / unloading position. The roller presses against the upper ring section of the lifting ring 15 and acts with the first roller 261. Under the action of the spring, the guide rod 26 makes the shower head positioning block 25 rise. At the same time, the lower arc groove of the push ring groove 121 makes the second roller 39 lowered and the sealing plug 36 lowered and disengaged, providing unobstructed space for the installation of the shower head 100.

[0036] Step 2: The shower carrier rotor 20 rotates, carrying the shower head 100 under test, and leaves the loading and unloading station. During its movement towards the water outlet testing station, the first roller 261 gradually moves from the lower ring section to the lower ring section along the transition connecting section of the roller pressing lifting ring 15, compressing the spring. The guide rod 26 is gradually pushed downwards, and the shower head positioning block 25 slides downwards along the vertical slide rail 24, pressing the shower head from above. Simultaneously, the second roller 39 climbs from the lower arc groove to the upper arc groove along the transition connecting groove of the push ring groove 121, gradually lifting the push bar 38 and causing the sealing plug 36 to rise. Its frustum-shaped head 361 extends into the threaded sleeve at the lower end of the shower handle to complete centering guidance, and the rubber sealing ring 363 on the end ring 362 presses against the end face of the threaded sleeve to achieve a sealing connection.

[0037] Step 3: When the shower head carrier rotor 20 delivers the shower head to the water outlet detection station, the shower head positioning block 25 has fully pressed the shower head, and the sealing plug 36 has formed a reliable seal with the shower head inlet. At this time, the solenoid valve 33 corresponding to this station opens, and the pressurized water in the water storage chamber 131 enters the shower head 100 through the sealing ring 31, radial water pipe 32, telescopic pipe 34, connector pipe 35, and sealing plug 36, and the shower head begins to spray water. The sprayed water is collected by the water receiving arc groove 41 and returned to the water tank 301 for recycling through the return pipe 43. At the same time, the CCD camera of the detection unit 50 continuously captures the water spray pattern of the shower head, and the images are transmitted to the host computer in real time for analysis and processing to determine whether the water outlet effect is qualified.

[0038] Step 4: After the inspection is completed, the solenoid valve 33 corresponding to this station closes, cutting off the water supply. The shower head carrier rotor 20 continues to rotate, sending the shower head back to the loading / unloading station. During this process, the first roller 261 rises along the roller pressing lifting ring 15 transition connection section to the upper ring section, and the shower head positioning block 25 moves up and down to disengage from the shower head; the second roller 39 descends along the push ring groove 121 transition connection groove back to the lower arc groove, and the sealing plug 36 descends to disengage from the shower head handle. After reaching the loading / unloading station, the shower head is removed manually or by an external robot according to the inspection results from the host computer and placed in the qualified or unqualified product area. At this point, a complete inspection cycle ends, and the shower head for the next station immediately enters the inspection process. Example 2

[0039] Example 2 discloses an online detection device for shower head water output effect that is further optimized based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.

[0040] like Figure 6 Appendix Figure 9 and Figure 10 As shown, in this embodiment 2, the water output detection of the shower head 100 with two-level adjustment function has been further designed. A protruding shift lever 101 is provided on the water output panel of the shower head 100. Rotating the shift lever 101 can adjust the water output level of the shower head 100.

[0041] In this embodiment, the detection unit 50 has at least two CCD cameras, which are respectively located on both sides of the upper end of the water-receiving arc groove 41. A shift adjustment mechanism 70 is provided on the water-receiving arc groove 41 between the two CCD cameras. The shift adjustment mechanism 70 includes a splined hollow cylinder 71 that is radially rotatably disposed on the outer arc surface of the water-receiving arc groove 41. A splined shaft 72 that can move radially is inserted into the radially inner end of the splined hollow cylinder 71. A prying part 73 that can act on the shift paddle 101 is fixedly connected to the inner end of the splined shaft 72. Then, a telescopic drive member 74 is fixedly installed at the radially outer end of the splined hollow cylinder 71. Specifically, the telescopic drive member 74 can be either an electric push rod or a hydraulic telescopic rod, and the telescopic end of the telescopic drive member 74 extends into the splined hollow cylinder 71 and connects to the outer end of the splined shaft 72. In addition, an adjusting motor 75 is fixedly installed on the outer arc surface of the water receiving arc groove 41. A first bevel gear is installed on the output shaft of the adjusting motor 75, and a second bevel gear 76 that meshes with the first bevel gear is installed on the spline hollow cylinder 71 located outside the water receiving arc groove 41. By adjusting the power input of the adjusting motor 75 and the meshing transmission between the bevel gears, the spline hollow cylinder 71, the spline shaft 72 and the actuating part 73 can be rotated together.

[0042] The working process of this embodiment 2 is as follows: The shower head first completes the first stage (first gear) water output test, and then the shower head carrier rotor 20 rotates it to the gear shifting position radially aligned with the gear shifting adjustment mechanism 70. At this time, the telescopic drive member 74 extends, pushing the spline shaft 72 to move along the spline hollow cylinder 71 towards the shower head until the actuating part 73 contacts and engages with the gear shifting paddle 101. Next, the adjusting motor 75 rotates at a preset angle, driving the actuating part 73 to rotate through the spline hollow cylinder 71 and the spline shaft 72, thereby actuating the gear shifting paddle 101 to complete the gear shifting. After the shifting is completed, the telescopic drive member 74 retracts, and the actuating part 73 resets and disengages. Subsequently, the shower head continues to rotate by the shower head carrier rotor 20 to the next water output test position to continue water flow, and the second CCD camera performs the second stage water output effect test.
