Description

Technical Field

[0001] This invention relates to the field of shower head life testing, and more particularly to a device for testing the life of shower head switching and ball head oscillation. Background Technology

[0002] A shower head is a type of rain shower appliance used in the bathroom. It usually has various types of small holes inside, and the water outlet is switched by rotating the adjustment dial, thereby controlling the water spray effect. In order to ensure the freedom of use of the shower head, there is a connector with a universal ball head on the market. With the cooperation of this connector, the spray angle of the shower head can be freely adjusted during the use of the shower head.

[0003] For showerheads with omnidirectional ball heads, various tests are typically conducted to assess their overall lifespan in order to ensure proper use after sale. Current showerhead oscillation tests usually involve a reciprocating mechanical structure that swings back and forth in a specific direction. Each angle change requires readjustment, resulting in a fixed-direction test. However, in daily household use, adjustments are mostly made in non-fixed directions. Therefore, while this type of test can represent the showerhead's lifespan to some extent, there is a discrepancy between the test process and actual use. It not only fails to accurately measure the showerhead's lifespan during actual use but also requires cumbersome angle adjustments. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides the following technical solution: Shower head switching and ball head swing life testing device, including: test frame and moving part sleeved on the outside of the arc frame.

[0005] Specifically, the test frame includes an arc-shaped frame and positioning rods at both ends of the arc-shaped frame. The positioning rods are axially rotatably fixed to the shower head mounting rod. The movable component moves along the arc-shaped frame. A telescopic rod is connected to the side of the movable component near the positioning rod. A positioning frame is fixed to the end of the telescopic rod. The positioning frame is filled with a positioning element made of elastic material.

[0006] As an improvement to the above technical solution, the side of the positioning member closest to the positioning rod is arc-shaped, and when the positioning member is in a vertical state, it faces the center position between the two positioning rods.

[0007] As an improvement to the above technical solution, a through air hole is provided at the center of the positioning component, and a slot connected to the air hole is provided on the surface of the positioning frame. An air pipe is provided in the slot, and the other end of the air pipe is connected to an air pump fixed on the telescopic rod.

[0008] As an improvement to the above technical solution, it includes: two sets of positioning plates arranged symmetrically, with an integrally formed fixing part in the middle of the positioning plate, the fixing part fitting the outer surface of the shower head mounting rod, and the positioning rod being detachably rotatably mounted on the outer surface of the fixing part.

[0009] As an improvement to the above technical solution, the surfaces of the two sets of fixing parts are provided with at least three mounting cavities. At least one mounting cavity is equipped with a motor, the power end of the motor is connected to a drive wheel, the end of the positioning rod is fixed with a connector, at least two mounting cavities are axially inserted and fixed with the connector, and at least one connector has a driven wheel integrally formed on its outer side. The drive wheel and the driven wheel are synchronously connected by a synchronous belt.

[0010] As an improvement to the above technical solution, the moving part includes a moving block, the middle of which has an inner cavity that fits the arc-shaped frame, the arc-shaped frame is inserted into the inner cavity, and a roller that rolls along the surface of the arc-shaped frame is provided on the side of the moving block away from the telescopic rod.

[0011] As an improvement to the above technical solution, the side of the movable block away from the telescopic rod is integrally formed with an extension portion. A through mounting groove is provided in the middle of the extension portion. The rotating wheel is disposed inside the mounting groove. A side groove communicating with the inner cavity is provided on the side of the mounting groove near the movable block. One side of the rotating wheel is embedded into the inner cavity by the side groove and fits the surface of the arc-shaped frame.

[0012] As an improvement to the above technical solution, a second motor is provided on one side of the extension, a drive wheel is fixed to the power end of the second motor, a connecting rod is integrally formed at the center of the rotating wheel, and a transmission wheel is connected to the other end of the connecting rod, the transmission wheel meshing with the drive wheel.

[0013] As an improvement to the above technical solution, the arc-shaped frame and the positioning rod are combined to form an arc-shaped structure. The arc-shaped frame and the positioning rod are made of metal materials, and the connection is arc-shaped.

[0014] The beneficial effects of this invention are: By cooperating with the curved frame and the moving parts, and combining the rotatability of the positioning rod, the free positioning of the moving parts within the spherical space can be controlled. Combined with the use of a universal ball head for fixing the shower head, it is possible to ensure that the shower head is fixed by the positioning parts and can be freely adjusted within the spherical space for testing. By simply setting a random path, the uncertainty of human operation can be simulated, thereby avoiding the testing process of a fixed path and better simulating the actual use testing process. This test result is more in line with the lifespan in actual use. Attached Figure Description

[0017] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0018] For showerheads with omnidirectional ball heads, various tests are typically conducted to assess their overall lifespan and ensure proper post-sale use. Current showerhead oscillation tests usually involve a reciprocating mechanical structure that swings back and forth in a specific direction. Each angle change requires readjustment, resulting in a fixed-direction test. However, most household adjustments are non-fixed. Therefore, while this type of test can represent the showerhead's lifespan to some extent, it differs significantly from actual use. It not only fails to accurately measure the showerhead's lifespan during real-world use but also requires cumbersome angle adjustments. To address this issue, the following embodiment is provided: Please see Figures 1 to 7A shower head switching and ball head swing life testing device is provided, including: a test frame 10 and a movable part 20 sleeved on the outside of the arc frame 11.

[0019] Specifically, the test frame 10 includes an arc-shaped frame 11 and positioning rods 12 disposed at both ends of the arc-shaped frame 11. The positioning rods 12 are axially rotatably fixed to the shower head mounting rod. The moving part 20 moves along the arc-shaped frame 11. A telescopic rod 23 is connected to the side of the moving part 20 near the positioning rod 12. A positioning frame 24 is fixed to the end of the telescopic rod 23. The interior of the positioning frame 24 is filled with a positioning part 241 of elastic material.

[0020] The movable component 20 on the arc frame 11 can form a movement function along an arc. When the arc frame 11 can rotate with the positioning rod 12, it forms a movement function on a spherical surface. For the universal ball joint, its steering is a spherical steering, the core of which is to change the angle around a circle. Therefore, by combining the arc frame 11, the positioning rod 12 and the movable component 20, a spherical rotation form is achieved. By controlling the extension and retraction of the positioning frame 24, the function of driving the whole structure to move freely on the spherical surface through the movable component 20 can be realized. This movement state can simulate random human operation in a random movement state, thereby realizing a more reasonable swing life test scheme and more accurate test results.

[0021] In addition, to ensure the stability of the structural components, the arc-shaped frame 11 and the positioning rod 12 are combined to form an arc-shaped structure. The arc-shaped frame 11 and the positioning rod 12 are made of metal materials, and the connection is curved.

[0022] The purpose of forming the bow-shaped structure here is to ensure the stability of the arc frame 11, while the arc-shaped bend at the connection is to ensure the detachability of the moving part 20 in the later stage. Due to the bend here, in the event of damage to the structure in the later stage, the entire structure can be removed from the edge by bending.

[0023] Since the positioning element 241 is made of an elastic material, in order to ensure that the positioning element 241 can securely lock the shower head, the following design is provided in this embodiment: The side of the positioning member 241 near the positioning rod 12 is arc-shaped, and when the positioning member 241 is in a vertical state, it faces the center position between the two positioning rods 12.

[0024] The spherical positioning element 241 contacts the surface of the shower head. Under pressure, the surface of the shower head is pressed into the interior of the positioning element 241. This prevents the shower head from falling off or coming loose during rotation. However, at higher oscillation frequencies, displacement may occur, and it may still fall off if the testing time is long. Therefore, the indentation effect needs to be improved. Based on this, the following design is proposed: The positioning component 241 has a through air hole 242 at its center, and the surface of the positioning frame 24 has a slot that connects to the air hole 242. An air pipe 232 is installed in the slot, and the other end of the air pipe 232 is connected to an air pump 231 fixed on the telescopic rod 23.

[0025] The air pump 231 and air pipe 232 create a negative pressure effect. When the entire shower head is squeezed into the positioning component 241, the air pump 231 draws air, thereby creating a certain negative pressure adsorption effect. Of course, in this case, the positioning component 241 cannot be made of porous material. Instead, it can be made of materials with a certain deformation effect and a certain deformation capacity, such as rubber. Based on this, combined with the negative pressure adsorption function, it can effectively ensure that the shower head will not loosen or fall off under high frequency testing. In addition, in order to avoid the air pipe 232 and air hole 242 from twisting and clogging, springs can be added inside the air pipe 232 and air hole 242. The springs ensure that no matter how the internal structure is twisted, there is always some space for air to pass through, ensuring that the air pump 231 can function normally.

[0026] In this embodiment, the device for fixing the shower head mounting rod includes two sets of symmetrically arranged positioning plates 14, specifically designed as follows: The positioning plate 14 has an integrally formed fixing part 141 in the middle. The fixing part 141 fits the outer surface of the shower head mounting rod, and the positioning rod 12 is detachably rotatably mounted on the outer surface of the fixing part 141.

[0027] The shower head mounting rod is fixed by two positioning plates 14 and bolts, ensuring that the entire device can be positioned on the outside of the shower head mounting rod. At this point, only the position and distance of the overall structure need to be adjusted to ensure that the test can start normally. Based on this, in order to further improve the structural design, the following embodiment is given: The surfaces of the two sets of fixing parts 141 are provided with at least three mounting cavities 142. At least one mounting cavity 142 is provided with a motor 143. The power end of the motor 143 is connected to a drive wheel 144. The end of the positioning rod 12 is fixed with a connector 13. At least two mounting cavities 142 are axially inserted and fixed with the connector 13. At least one connector 13 has a driven wheel 131 integrally formed on its outer side. The drive wheel 144 and the driven wheel 131 are synchronously connected by a timing belt 15.

[0028] The motor 143 drives the drive wheel 144 to rotate, and the synchronous belt 15 drives the driven wheel 131 to rotate. Since the two connectors 13 use an insert-type fixing method, they are combined... Figure 2 and Figure 5As can be seen from the pattern, the connector 13 can rotate, so the rotation of the driven wheel 131 will drive the entire positioning rod 12 to rotate, thereby realizing the free adjustment of the moving part 20 on the spherical surface. The motor 143 and the connector 13 are fixed by the mounting cavity 142 respectively. The motor 143 is fixed by auxiliary bolts, while the connector 13 is positioned by adding auxiliary parts such as bearings inside to lock and maintain rotation.

[0029] In one embodiment, the movable member 20 includes a movable block 21, the middle of which has an inner cavity 211 that fits the arc frame 11, the arc frame 11 is inserted into the inner cavity 211, and a roller 222 that rolls along the surface of the arc frame 11 is provided on the side of the movable block 21 away from the telescopic rod 23.

[0030] The rolling of the roller 222 on the surface of the arc-shaped frame 11 drives the entire moving block 21 to move on the arc-shaped frame 11. Combined with the rotation of the positioning rod 12, it can move to any point on the spherical surface, perfectly matching the rotation of the universal ball joint. Figure 1 The rotation of the sphere is given as a semicircle, but those skilled in the art should know that the moving surface of the moving block 21 can be increased by using a larger angle and more flexible turning, instead of just moving on the hemisphere.

[0031] To further improve the structural design of the rotor 222, the following design is given in this embodiment: The movable block 21 has an integrally formed extension 22 on the side away from the telescopic rod 23. The extension 22 has a through mounting groove 221 in the middle. The rotating wheel 222 is disposed inside the mounting groove 221. The mounting groove 221 has a side groove 212 that communicates with the inner cavity 211 on the side near the movable block 21. One side of the rotating wheel 222 is embedded into the inner cavity 211 by the side groove 212 and fits against the surface of the arc frame 11.

[0032] The rotating wheel 222 is mounted on the outside of the arc frame 11 via the mounting slot 221 to avoid interference during testing. It engages with the arc frame 11 via an internal side slot 212, allowing the rotating wheel 222 to rotate within the extension 22 and confined within the mounting slot 221. The communication of the side slot 212 enables the entire moving block 21 to move on the arc frame 11. Furthermore, the rotation of the rotating wheel 222 is achieved in the following manner: A second motor 224 is provided on one side of the extension 22. A drive wheel 225 is fixed to the power end of the second motor 224. A connecting rod is integrally formed at the center of the rotating wheel 222, and a transmission wheel 223 is connected to the other end of the connecting rod. The transmission wheel 223 meshes with the drive wheel 225.

[0033] Power is provided by a motor 224 located on the side, which drives the transmission wheel 223 to rotate via the drive wheel 225, thereby driving the rotating wheel 222 to rotate synchronously.

[0034] Since the connector 13 is added here, the previously designed movable part 20 will be blocked from being directly removed. Based on this, it is possible to consider making the structure of the movable block 21 a combination of two shells, which can then be fixed with bolts. In this way, the entire movable block 21 can be disassembled into two parts and the structure can be removed directly.

[0035] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Anyone skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
