Description

Technical Field

[0001] This utility model relates to a shampoo head pad adjusting water spray structure, and belongs to the technical field of shampoo machine accessories. Background Technology

[0002] Existing shampoo machines require the head to enter the shampoo chamber for support via a built-in head cushion. However, these cushions typically lack a water spray function and cannot provide stable support to the back of the head simultaneously. Furthermore, because existing head cushions are fixed, their angle cannot be flexibly and stably adjusted for support. For example, our company's independently developed double-layer inflatable water-spraying soft cushion (Chinese patent application number 202521434441.2) consists of a lower air bladder and an upper water bladder, which are designed as separate parts. The combination of the air and water bladders improves the support comfort of the head cushion and allows adjustment of the water spray angle from the upper water bladder, thus simultaneously providing support and rinsing the bottom of the head, improving overall user comfort. However, after testing, it was found that while the inflation and deflation of the lower air bladder allows for adjustment of the water spray angle, the precision of this adjustment needs improvement, and the overall support stability also needs strengthening. Therefore, our company proposes an improved shampoo machine head cushion water spray adjustment structure. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shampoo head pad adjusting water spray structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a shampoo head pad adjustment spray structure, including a fixed support plate, on which a rubber spray pad is movably disposed, and a mechanical drive unit for driving the rubber spray pad to rotate is installed on one side of the fixed support plate.

[0005] A further improvement is that the mechanical drive unit includes an adjusting movable plate and a telescopic push rod. The adjusting movable plate is hinged to the upper side of the fixed support plate, and the telescopic push rod is vertically inclined and installed on the lower side of the fixed support plate. The telescopic end of the telescopic push rod is movably connected to the lower side of the adjusting movable plate.

[0006] A further improvement is that the telescopic push rod is equipped with a pin shaft at its telescopic end, and a lower protrusion is integrally provided on the lower side of the adjusting movable plate, with a movable groove in the middle of the lower protrusion for the pin shaft to pass through and move.

[0007] A further improvement is that the rubber spray pad includes an upper flexible spray cover and a lower protective shell. The upper flexible spray cover and the lower protective shell are integrally molded or bonded together as a whole. A water cavity is provided between the lower side of the upper flexible spray cover and the upper side of the lower protective shell, and the lower protective shell has a water inlet communicating with the water cavity. The upper side of the upper flexible spray cover has multiple water spray holes communicating with the water cavity.

[0008] A further improvement is that the mechanical drive unit is located inside the lower protective shell and is surrounded by the lower protective shell, and the adjusting movable plate is fixedly connected to the top of the inner side of the lower protective shell.

[0009] A further improvement is that a water pipe is connected to the top of the inner side of the lower protective shell. This water pipe is connected to a water inlet and is distributed through the middle of the adjusting movable plate.

[0010] Compared with the prior art, the present invention has the following advantages: This invention mainly uses the top of the rubber spray pad to flexibly support the head, and sets a water cavity between the upper flexible spray cover and the lower protective shell to increase the space distance between them. Combined with the elasticity of rubber, it reduces the pain of supporting the head and improves comfort. The entire rubber spray pad is mounted on the mechanical drive unit, which improves the support stability of the rubber spray pad. Furthermore, the rotation angle of the flexible spray cover on the top of the rubber spray pad can be adjusted by the telescopic push rod and the adjusting movable plate of the mechanical drive unit. This allows for stable support of the head while adjusting the rotation angle of the flexible spray cover for water spraying, greatly improving the overall performance. The lower protective shell is designed around the adjustment plate, pin shaft, and telescopic push rod of the mechanical drive unit. This reduces the direct contact of liquid with the parts, providing waterproof protection and thus extending the service life of the parts. Attached Figure Description

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Please see Figures 1-4 This utility model provides a technical solution for adjusting the water spray structure of a shampoo head pad: it includes a fixed support plate 1, on which a rubber water spray pad 2 is movably mounted. A mechanical drive unit for rotating the rubber water spray pad 2 is installed on one side of the fixed support plate 1. The mechanical drive unit includes an adjusting movable plate 3 and a telescopic push rod 4. The adjusting movable plate 3 is hinged to the upper side of the fixed support plate 1 and is horizontally positioned towards the front. The telescopic push rod 4 is vertically inclined and installed on the lower side of the fixed support plate 1. The telescopic end of the telescopic push rod 4 is movably connected to the lower side of the adjusting movable plate 3. A pin shaft 33 is installed on the telescopic end of the telescopic push rod 4. A lower protrusion 31 is integrally provided on the lower side of the adjusting movable plate 3, and a movable groove 32 for the pin shaft 33 to pass through is opened in the middle of the lower protrusion 31. The rubber water spray pad 2 includes an upper flexible water spray cover 21 and a lower protective shell 22. The upper flexible spray cover 21 and the lower protective shell 22 are integrally molded or bonded together as a whole. A water cavity 23 is provided between the lower side of the upper flexible spray cover 21 and the upper side of the lower protective shell 22 to increase the spacing space. The lower protective shell 22 has a water inlet 24 that communicates with the water cavity 23. The upper flexible spray cover 21 has multiple water spray holes 25 that communicate with the water cavity 23 on its upper side, so that the upper flexible spray cover 21 has a water spraying function. The mechanical drive unit is located inside the lower protective shell 22 and is surrounded by the lower protective shell 22 to achieve a waterproof effect. The adjusting movable plate 3 is fixedly connected to the top of the inner side of the lower protective shell 22. Therefore, by retracting the telescopic push rod 4, the adjusting movable plate 3 can be rotated downward, which simultaneously pulls the upper flexible spray cover 21 downward and causes the lower protective shell 22 to deform. The angle and support effect of the upper flexible spray cover 21 can be precisely and stably adjusted.

[0014] The lower protective shell 22 has a water pipe 26 connected to the top of the inner side of the lower protective shell 22. The water pipe 26 is connected to the water inlet 24 and is distributed through the middle of the adjusting movable plate 3. Therefore, when the adjusting movable plate 3 rotates, it can drive the water pipe 26 to rotate at the same angle, so that it rotates synchronously with the upper flexible spray cover 21 to ensure continuity.

[0015] In actual use, the user's head and neck rest on the upper flexible spray cover 21 on the upper side of the rubber spray pad 2. Because the upper flexible spray cover 21 is made of soft rubber and has a water cavity 23 with a certain space on its lower side, it is comfortable and soft to the touch, reducing discomfort. Furthermore, since the lower protective shell 22 on the lower side of the water cavity 23 is connected to the adjusting movable plate 3 of the mechanical drive unit, and the adjusting movable plate 3 is supported by the telescopic push rod 4, the support structure of the entire rubber spray pad 2 is more stable. When water spraying is needed, the external water pump works to send liquid into the water cavity 23 through the water pipe 26. The water cavity 23 sprays water directly onto the head and neck through the various spray holes 25. Furthermore, through the telescopic action of the telescopic push rod 4, the pin shaft 33 can push and pull the movable groove 32 of the adjusting movable plate 3, allowing the adjusting movable plate 3 to rotate up and down on the fixed support plate 1. After the adjusting movable plate 3 rotates, it synchronously drives the upper flexible spray cover 21 of the rubber spray pad 2 to rotate, realizing the stable and precise adjustment of the spray angle of the rubber spray pad 2 to rinse different positions at the bottom of the head, thus improving the range of use. Moreover, during the rinsing process, the lower protective shell 22 can protect the telescopic push rod 4 and the adjusting movable plate 3 from getting wet. The lower protective shell 22 is also made of rubber, so when the telescopic push rod 4 extends and retracts, it can also adapt to the deformation of the adjusting movable plate 3, without causing mechanical interference.

The functions, components and structures not mentioned can be implemented by using existing components and structures that can achieve the corresponding functions. For example, in this embodiment, the telescopic push rod 4 is an electric push rod, or it can be replaced by accessories with telescopic functions such as pneumatic telescopic rods and hydraulic telescopic rods in the prior art.
