Description
Technical Field
[0001] The utility model relates to the technical field of daily necessities for bathing and back scrubbing, in particular to a foldable manipulator for bathing. Background Art
[0002] In northern China, scrubbing the body is an important cultural activity, and the tools used for scrubbing the body include a bath towel and a bath sponge. The applicant's previously applied-for anti-slip foldable back-scrubbing robot comprises a robot palm and a rotating arm. The robot palm comprises a palm portion and a rotating arm connecting portion, which is connected to the rotating arm via a connecting shaft. An anti-slip hook is machined on the outer side of the connecting end between the rotating arm and the robot palm. After the bath towel is put on the robot palm, the fastening ear on the bath towel is hung on the anti-slip hook. When the rotating arm is bent and unfolded, the fastening ear on the bath towel is tightened, thereby securing the bath towel. When bathing, the back-scrubbing robot can be used to clean various parts of the body independently. However, after long-term use, the back-scrubbing robot was found to still have the following defects: (1) The design of the connection structure between the robot palm and the rotating arm is not reasonable enough. The robot palm and the rotating arm are easily disengaged during scrubbing, resulting in connection failure, and the rotating arm needs to be bent again for secondary connection; (2) During bathing, the hands are wet and slippery, and the rotating arm cannot be tightly gripped, resulting in a lack of strength when scrubbing; (3) It can only fix the bath towel, but not the bath sponge.

[0036] like Figures 1 to 10As shown, in this embodiment, a foldable manipulator for bathing is provided, comprising a manipulator palm 1 and a rotating arm 2. The manipulator palm 1 comprises a palm portion 11 and a rotating arm connecting portion 12, and the rotating arm connecting portion 12 is connected to the rotating arm 2 through a connecting shaft 3; the rotating arm 2 is provided with a snap-fitting tongue 4 at one end close to the rotating arm connecting portion 12, and the snap-fitting tongue 4 protrudes from the outer side surface of the rotating arm 2 and leaves a gap with the rotating arm 2, the root of the snap-fitting tongue 4 is connected to the rotating arm 2, and the outer side surface of the snap-fitting tongue 4 is at A snap-fitting protrusion 41 is provided at one end close to the rotating arm connecting part 12; a snap-fitting groove 121 is provided on the rotating arm connecting part 12 on a side adjacent to the rotating arm 2 for cooperating with the snap-fitting protrusion 41 to achieve snap-fitting; when the rotating arm 2 is bent and unfolded, the snap-fitting protrusion 41 on the snap-fitting tongue 4 is snapped with the rotating arm connecting part 12, and at this time, the back-scrubbing robot can be used to independently clean various parts of the body; when the rotating arm 2 is bent and folded, a gap is left between the palm part 11 and the rotating arm 2 for accommodating a bath sponge.
[0037] Further, continue as Figures 1 to 9 As shown, in this embodiment, a hand-holding portion 21 is provided at the upper end of the rotating arm 2, and a thumb notch 211 is provided on the inner side of the hand-holding portion 21 at a position opposite to the thumb. When scrubbing the body, the user holds the hand-holding portion 21 with the thumb placed in the thumb notch 211, which is convenient for the user to scrub the body vigorously and can also prevent the hand from slipping.
[0038] Further, if Figures 1 to 7 As shown, in this embodiment, the palm portion 11 includes a top plate 111, multiple transverse partitions 112, and two longitudinal connecting ribs 113. The rotating arm connecting portion 12 is arranged on the top surface of the top plate 111, and multiple transverse partitions 112 are arranged on the bottom surface of the top plate 111 at horizontal intervals along the palm portion 11. The two longitudinal connecting ribs 113 are arranged on both sides close to the top plate 111, and are used to connect the multiple transverse partitions 112 together, so that a plurality of hollow grooves 115 are formed on the side of the palm portion 11 that contacts the human body. The hollow grooves 115 are used to install bath sponges. At the same time, the design of the hollow grooves 115 also achieves weight reduction and cost reduction, and is also convenient for cleaning the palm portion 11.
[0039] Further, continue as Figure 7 As shown, in this embodiment, the palm portion 11 also includes a longitudinal partition 114, and the longitudinal partition 114 is arranged in the middle of the transverse partition 112. The arrangement of the longitudinal partition 114 can form more hollow grooves 115 on the palm portion 11, so that the bath sponge and the palm portion 11 are installed more firmly; in addition, the overall strength of the palm portion 11 can also be ensured.
[0040] Further, if Figure 4 、 Figure 5As shown, in this embodiment, the palm portion 11 is located at the outer side surface of the horizontal partition 112 at the lower end, and the thumb notch 211 is a C-shaped groove. After the rotating arm 2 is bent and folded, the limiting protrusion 2111 at the lower end of the thumb notch 211 contacts the limiting groove 1121 to achieve limitation, so that the palm portion 11 remains horizontal after the manipulator is folded and a gap is left between it and the rotating arm 2.
[0041] Furthermore, the limiting groove 1121 has an inclined surface on one side adjacent to the top plate 111 and a vertical surface on the other side. The concave angle between the vertical surface and the inclined surface is an acute angle. When the palm 11 is pressed hard, the limiting protrusion 2111 at the lower end of the thumb notch is interference fit with the limiting groove 1121.
[0042] Further, if Figure 1 As shown, in this embodiment, an anti-detachment hook 5 is processed on the outer side of the connection end of the rotating arm 2 and the robotic palm 1. When the rotating arm 2 is bent to be folded or unfolded, the anti-detachment hook 5 does not interfere with the rotating arm connection part 12 of the robotic palm 1. After the bath towel is put on the robotic palm 1, the fastening ears on the bath towel are hung on the anti-detachment hook 5. When the rotating arm 2 is bent and unfolded, the fastening ears on the bath towel are tightened to fix the bath towel.
[0043] like Figure 10 As shown, in this embodiment, the bath sponge 6 is provided with a plug-in block 61 that matches the hollow groove 115. The plug-in block 61 is a variable-size structure. The size of the end of the plug-in block 61 is smaller than the size of the root. The end is clearance-fitted with the hollow groove 115, and the root is interference-fitted with the hollow groove 115, which makes it convenient to insert the plug-in block 61 into the hollow groove 115. When the bath sponge is needed, just remove the bath towel, and then align the plug-in block 61 of the bath sponge 6 with the hollow groove 115, and then press hard to complete the installation of the bath sponge 6.
[0044] Further, if Figure 8 As shown, in this embodiment, the rotating arm 2 and the robot palm 1 are an integrated structure made by 3D printing or injection molding, and a plurality of weight-reducing holes 22 are provided on the rotating arm 2, which further reduces the overall weight of the robot, saves processing materials, and reduces costs.
[0045] The above are specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
