DETAILED DESCRIPTION
[0021] The present application is described in detail below in conjunction with the drawings.
[0022] As Figures 1-17 shown, the present application provides a multifunctional bath brush, comprising: The handle 1 includes a grip portion 11, a connecting rod portion 12 connected to the grip portion 11, and a mounting end portion 13 connected to the connecting rod portion 12. The mounting end portion 13 is located at the end of the connecting rod portion 12 away from the grip portion 11, and the mounting end portion 13 has a first mating portion. Brush head 2 is mounted on the mounting end 13 of the handle 1. The brush head 2 has a brush head mounting surface 201 and a brush head working surface 202. A mounting dihedral angle α is formed between the brush head mounting surface 201 and the brush head working surface 202. The brush head mounting surface 201 has a second mating part, which is used to mate with the first mating part of the mounting end 13, so that the brush head 2 has at least three mating states relative to the connecting rod part 12. In different mating states, the brush head 2 has different orientations. The handle 1 has two connecting rod portions 12, which are arranged in a "V" or "U" shape. Each of the two connecting rod portions 12 is connected to the brush head 2 through the mounting end 13. The brush heads 2 on the two connecting rods 12 are oriented in the same or opposite directions, so that the bath brush has at least a first use state, a second use state and a third use state; Please refer to the reference. Figure 5 and Figure 6 When the bath brush is in the first use state, the brush heads 2 on the two connecting rods 12 are oriented in the same direction, and the orientation is biased towards the grip 11 (see...). Figure 5 (in the E1 direction), at this time, the orientation of the brush head 2 has an angle of 30°~70° with the length direction D of the grip, and the end faces of the two brush heads 2 are coplanar; This mode can be used to wash the back: the user holds the handle 11, the brush head 2 extends to the back, and the bath brush is slid up, down, left and right to wash the back. This mode is especially suitable for the elderly. On the one hand, the two brush heads 2 increase the washing area, which makes it easier to improve the washing efficiency. On the other hand, the brush head 2 facing the handle 11 is easier to fit the back skin, and the user does not need to push the arm back too much, resulting in a better user experience.
[0023] Please refer to the reference. Figures 7-9 When the bath brush is in the second use state, the brush heads 2 on the two connecting rods 12 are oriented opposite to each other (see...). Figure 9 (in the directions of E2 and E3), a washing dihedral angle c is formed between the working surfaces 202 of the two brush heads 2; This configuration can be used to wash the limbs (mainly the thighs and calves): The user holds the grip part 11 with their hand, places the brush head 2 on the limb, and the washing dihedral angle c formed between the working surfaces 202 of the two brush heads 2 can adapt to the circumferential curvature of the limb 3 (please refer to...). Figure 10Furthermore, the four limbs 3 can be positioned precisely between the two brush heads 2, increasing the washing area while preventing slippage. In this mode, the user has greater scrubbing angle and a larger washing area. This mode reduces the effort required for bathing and is particularly suitable for the elderly, allowing them to bathe efficiently with less body bending.
[0024] Please refer to the reference. Figure 11 and Figure 12 When the bath brush is in the third use state, the brush heads 2 on the two connecting rods 12 are oriented in the same direction, and are oriented away from the side of the grip 11 (see...). Figure 12 (in the E4 direction), at this time, the orientation of the brush head 2 has an angle of 110°~140° with the length direction D of the grip, and the end faces of the two brush heads 2 are coplanar; This state can be used to wash the instep and ankle (especially when sitting): the user holds the handle 11 and places the brush head 2 on the instep or ankle to achieve a long-distance bathing.
[0025] In one embodiment, when the bath brush is in the second use state, the working surfaces 202 of the brush heads 2 on the two mounting ends 13 have a washing dihedral angle c of 100° to 160°, preferably 120° to 130°.
[0026] Please refer to the reference. Figure 1 and Figure 2 In one embodiment, the brush head is rotatably mounted on the handle; the mounting end 13 is formed with a handle mounting surface 131, the first mating part is disposed on the surface of the handle mounting surface 131, the first mating part includes a protrusion 24, and the second mating part includes a recess 14; The concave points 14 include a first concave point 141, a second concave point 142, a third concave point 143, and a fourth concave point 144 arranged in a circumferential array. The convex points 24 respectively limit and cooperate with the first concave point 141, the second concave point 142, the third concave point 143, and the fourth concave point 144, so that the brush head 2 has four different orientations: The mounting dihedral angle a formed between the brush head mounting surface 201 and the brush head working surface 202 causes the brush head 2 to have a thick side end 223 and a thin side end 224 that are arranged oppositely. The thin side end 224 is the side end of the brush head 2 that is close to the intersection line of the mounting dihedral angle a. When the protrusion 24 and the first concave point 141 are engaged, the longitudinal section of the line connecting the thick end 223 to the thin end 224 on the brush head 2 coincides with or is parallel to the length direction D of the grip portion, and the thin end 224 of the brush head 2 is positioned closer to the grip portion 11, and the orientation of the brush head 2 is biased towards the grip portion 11 (see...).Figure 5 (Central E1 direction) When the protrusion 24 and the second concave point 142 are engaged, the longitudinal section of the line connecting the thick end 223 to the thin end 224 of the brush head 2 intersects the length direction D of the grip portion. The thin end 224 of the brush head 2 is positioned away from the grip portion 11. The orientation of the brush head 2 away from the grip portion 11 (see...) Figure 9 (Central E2 direction) When the protrusion 24 and the third concave point 143 are engaged, the longitudinal section of the line connecting the thick end 223 to the thin end 224 on the brush head 2 coincides with or is parallel to the length direction D of the grip portion, and the thin end 224 of the brush head 2 is positioned away from the grip portion 11. The orientation of the brush head 2 away from the grip portion 11 (see...) Figure 12 Center E4 direction); When the protrusion 24 and the fourth concave point 144 are engaged, the longitudinal section of the line connecting the thick end 223 to the thin end 224 of the brush head 2 intersects the length direction D of the grip portion. The thin end 224 of the brush head 2 is positioned away from the grip portion 11, and the orientation of the brush head 2 is away from the grip portion 11. Furthermore, the orientation of the brush head 2 is in a state of relative opposition to the orientation when the protrusion 24 and the second concave point 142 are engaged (see...). Figure 9 (Central E3 direction). In this application, the two orientations are specifically opposite in terms of the longitudinal section of the brush head where the line connecting the second concave point 142 and the fourth concave point 144 is located.
[0027] In actual use, the protrusion 24 of one brush head 2 is matched with the second concave point 142 for limiting, and the protrusion 24 of the other brush head 2 is matched with the third concave point 143 for limiting, so that the bath brush can be in the second use state described above.
[0028] In one specific embodiment, the first concave point 141, the second concave point 142, the third concave point 143 to the fourth concave point 144 are arranged in a cross shape, and the protrusions rotate 90° in sequence to cooperate with the next concave point.
[0029] In another embodiment, the first mating portion includes a recess, and the second mating portion includes a protrusion.
[0030] In one specific embodiment, the plane containing the handle mounting surface 131 has a handhold angle b of 5° to 7° with the length direction D of the grip portion.
[0031] In one specific embodiment, the connecting rod portion 12 is configured with an arc-shaped structure at one end for connecting to the brush head 2.
[0032] The setting of the handhold angle b, combined with the arc structure of the connecting rod 12, can balance the orientation of the brush head 2 with the user's grip direction when washing, reducing the degree of bending or folding required by the hand, thereby improving the user's bathing comfort.
[0033] In another embodiment, the plane containing the handle mounting surface 131 is parallel to the length direction D of the grip portion.
[0034] In actual use, there can be 2, 3 or 4 protrusions 24. The position of each protrusion 24 is set to correspond to each concave point 14. When one of the protrusions 24 is engaged with one of the first concave point 141, the second concave point 142, the third concave point 143 or the fourth concave point 144, the other protrusions 24 are engaged with the other concave points 14 respectively, thereby enhancing the stability of the engagement.
[0035] In actual use, provided that the number of concave points 14 does not exceed the number of convex points 24, the more convex points 24 there are, the more stable the limiting fit of the brush head 2 will be. Correspondingly, a slightly larger force is required when adjusting the orientation of the brush head 2.
[0036] In another embodiment, the brush body 21 and the brush body mounting base 22 are integrally formed.
[0037] In another embodiment, the first mating part is a buckle, and the second mating part is a locking hole. There are multiple buckles or multiple locking holes. Different buckles engage with different locking holes, or buckles engage with different locking holes, so that the brush body 21 has different orientations. In this case, the mounting shaft 15 and the mounting sleeve 23 can be omitted. Instead, the brush head 2 can be disassembled and reinstalled to adjust the orientation of the brush body 21.
[0038] In another embodiment, a motor is also included, which is fixedly mounted in the mounting end, and the output shaft of the motor forms the first mating part; The brush head mounting surface has a snap-fit structure, which is used to fix the brush head on the output shaft of the motor. The rotation of the output shaft of the motor drives the brush head to rotate, so that the brush head has different orientations.
[0039] Please refer to Figure 1 In one embodiment, the brush head 2 includes a brush body 21 and a brush body mounting base 22; The plane containing the cross-section of the brush body 21 is the working surface 202 of the brush head 2; The brush body mounting base 22 has a first surface 221 and a second surface 222, the first surface 221 being the brush head mounting surface 201, and the second surface 222 being parallel to the cross-section of the brush body 21; The brush body 21 is detachably mounted on one side of the second surface 222 of the brush body mounting base 22.
[0040] In one specific embodiment, the brush body 21 has an external thread structure, and the brush body mounting base 22 has an internal thread structure. The external thread structure and the internal thread structure cooperate to so that the brush body 21 is helically connected to the brush body mounting base 22. The external thread structure also has a locking structure 211 to prevent the brush body 21 from rotating excessively.
[0041] In another embodiment, the brush body 21 can also be snap-fitted and detachably mounted on the brush body mounting base 22.
[0042] In another embodiment, the brush body 21 and the brush body mounting base 22 are integrally formed.
[0043] Please refer to Figure 13 and Figure 14 In one embodiment, the bath brush also has a fourth usage state. When the bath brush is in the fourth usage state, the thick ends 223 of the two brush body mounting seats 22 are close to each other, and the brush heads 2 on the two connecting rod portions 12 are facing away from each other (see...). Figure 14 In the E5 and E6 directions, the working surfaces 202 of the two brush heads 2 form a back-to-back angle d of 220° to 240°. At this time, the two brush heads 2 can be set as brush heads with different structures (for example, a combination of silicone contact brush head and bristle brush head, or a combination of bath ball brush head and bath towel brush head, or a combination of silicone contact brush head and bath towel brush head). After using one type of brush head (scrubbing), the other type of brush head can be used (bathing or massage).
[0044] Please refer to Figure 1 , Figures 15-17 In one embodiment, the brush head 2 is at least one of a bath ball brush head, a silicone contact brush head, a bristle brush head, and a bath towel brush head; When the bath brush is in the first use state, the second use state, and the third use state, the brush heads 2 connected to the two connecting rods 12 through the mounting end 13 are preferably of the same type.
[0045] When the bath brush is in the fourth usage state, the two connecting rods 12 are connected to different types of brush heads 2 via the mounting end 13, such as... Figure 13 , Figure 14 The silicone contact head shown is combined with the bath towel brush head.
[0046] Correspondingly, bath sponge brush heads are mainly used for foaming baths, bristle brush heads and bath towel brush heads are mainly used for scrubbing, and silicone contact brush heads are mainly used for massage.
[0047] In actual use, different brush heads can be formed by replacing the corresponding brush body 21.
[0048] When the bath brush is equipped with multiple different types of brush heads, users can change them as needed, making the bath brush more practical and functional.
[0049] In one specific embodiment, the brush body 21 includes a mounting structure and a contact structure disposed on the mounting structure, the contact structure being used to contact the body for bathing. The brush body 21 is mounted on a brush body mounting base 22 via the mounting structure. An external thread structure is disposed on the mounting structure.
[0050] In one embodiment, the two brush heads 2 have the same installation height relative to the grip portion 11, and there is an appropriate distance (1cm~5cm) between the brush body mounting bases 22 of the two brush heads 2, so that the two brush bodies 21 are arranged in a compact interval (first use state, second use state), or the two brush bodies 21 are arranged in contact with each other (third use state).
[0051] In one embodiment, the degree of the installation dihedral angle α is 20°~50°, preferably 30°, 35° or 45°.
[0052] Please refer to the reference. Figure 1 , Figure 2 and Figure 4 In one embodiment, the mounting end 13 of the handle 1 has a mounting shaft 15, and the brush head 2 has a mounting sleeve 23. Alternatively, the mounting end 13 of the handle 1 has a mounting sleeve 23, and the brush head 2 has a mounting shaft 15. The mounting sleeve 23 is fitted over the mounting shaft 15, so that the brush head 2 is rotatably mounted on the handle 1. At the same time, the limiting flange 16 also presses the brush body mounting seat 22 tightly against the brush head mounting surface 201.
[0053] In one embodiment, the end of the mounting shaft 15 away from the connecting rod portion 12 has a limiting flange 16. When the mounting sleeve 23 of the brush body mounting base 22 is installed on the mounting shaft 15, the limiting flange 16 is used to restrict the brush head 2 from being dislodged from the mounting shaft 15.
[0054] In one embodiment, the limiting protrusion 16 and the mounting sleeve 23 of the brush body mounting base 22 are respectively formed with guide slopes 161, which are used to facilitate the assembly and disassembly of the brush body mounting base 22.
[0055] In one embodiment, the mounting shaft 15 is a hollow tubular structure with a longitudinally arranged buffer groove. The buffer groove facilitates the smooth insertion of the mounting sleeve 23 when the mounting shaft 15 deforms.
[0056] In one embodiment, the grip portion 11 is provided with a hook hole for attaching the bath brush.
[0057] In one embodiment, the grip portion 11, the connecting rod portion 12, and the mounting end portion 13 of the handle 1 are integrally formed.
