Hair washing / massage apparatus for hair washing machine

Abstract

A hair washing / massage apparatus for a hair washing machine comprises a mounting base and a hair washing hood; a buffer assembly is arranged on the mounting base and the hair washing hood. When the hair washing hood rotates relative to the mounting base, the buffer assembly pulls on the hair washing hood in the direction opposite to the direction of rotation, which causes the hair washing hood to have a tendency toward rotation in the opposite direction. The buffer assembly comprises first rotational bases, second rotational bases, and first elastic parts. When the hair washing hood rotates relative to the mounting base, the buffer assembly pulls on the hair washing hood, which causes the hair washing hood to have a tendency toward rotation in the opposite direction. Thus, when the hair washing hood rotates relative to the mounting base to wash / massage the user's head, the force applied to the head is a gentle one that resembles the rubbing force that would be used by a person, thereby improving the user experience. Because the first rotational bases are rotationally connected to the mounting base and the second rotational bases are rotationally connected to the hair washing hood, when the hair washing hood rotates relative to the mounting base, the rotation of the first elastic pieces is smooth, providing good adaptability.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Embodiment: As shown in Figure 1-12, the hair washing and massaging device used in a hair washing machine includes a mounting base 1 and a hair washing cover 2. The hair washing cover 2 is arranged on the mounting base 1 and can rotate relative to the mounting base 1. A buffer component 3 is provided on the mounting base 1 and the hair washing cover 2. When the hair washing cover 2 rotates relative to the mounting base 1, the buffer component 3 pulls the hair washing cover 2 in a direction opposite to the rotation direction of the hair washing cover 2, so that the hair washing cover 2 has a tendency to rotate in the opposite direction. Specifically, the buffer assembly 3 includes a first rotating seat 301, a second rotating seat 302 and a first elastic member 303. The first rotating seat 301 is rotatably connected to the mounting seat 1, and the second rotating seat 302 is rotatably connected to the shampooing cover 2. One end of the first elastic member 303 is connected to the first rotating seat 301 and the other end is connected to the second rotating seat 302. When the shampooing cover 2 rotates relative to the mounting seat 1, the first rotating seat 301 rotates relative to the mounting seat 1, the second rotating seat 302 rotates relative to the shampooing cover 2, and the first elastic member 303 rotates with the shampooing cover 2 and elastically stretches. When the shampooing cover 2 rotates relative to the mounting seat 1, the first elastic member 303 elastically stretches, causing the shampooing cover 2 to have a tendency to rotate in the opposite direction. The present embodiment provides a shampooing and massaging device applied to a shampooing machine to solve the problem that the shampooing cover of the existing shampooing machine has too strong a force acting on the user's head and the user experience is poor. The main method is to configure a buffer component 3 on the mounting base 1 and the shampooing cover 2. When the shampooing cover 2 rotates relative to the mounting base 1, the buffer component 3 pulls the shampooing cover 2 in the direction opposite to the rotation direction of the shampooing cover 2, so that the shampooing cover 2 has a tendency to rotate in the opposite direction. Since the buffer component 3 pulls the shampooing cover 2 in the direction opposite to the rotation direction of the shampooing cover 2 when the shampooing cover 2 rotates relative to the mounting base 1, the force acting on the user's head when the shampooing cover 2 rotates relative to the mounting base 1 to wash / massage the user's head is softened, close to the force of manual kneading, and the user's experience is improved. Furthermore, since the buffer assembly 3 includes a first rotating base 301, a second rotating base 302 and a first elastic member 303, the first rotating base 301 is rotatably connected to the mounting base 1, and the second rotating base 302 is rotatably connected to the shampooing cover 2, the first elastic member 303 rotates smoothly when the shampooing cover 2 rotates relative to the mounting base 1, and the adaptability is good.

[0032] In the embodiment of the present invention, the mounting base 1 includes a first connecting base 101, which includes a first accommodating cavity (not shown in the figure), and a first rotating base 301 including a first ball seat 304 and a first hook 305. The first ball seat 304 is accommodated in the first accommodating cavity, and the first hook 305 is connected to the first ball seat 304 and to the first elastic member 303. When the shampoo cover 2 rotates relative to the mounting base 1, the first ball seat 304 rotates relative to the first connecting base 101 with its ball center as the axis. Because the first rotating base 301 includes the first ball seat 304, the first ball seat 304 rotates relative to the first connecting base 101 with the ball center of the first ball seat 304 as the axis when the shampoo cover 2 rotates relative to the mounting base 1, thereby allowing the first rotating base 301 to rotate smoothly and provide excellent adaptability.

[0033] In the embodiment of the present invention, the shampoo cover 2 has a second connecting seat 201, which has a second accommodating cavity (not shown in the figure). The second rotating seat 302 has a second ball seat 306 and a second hook 307. The second ball seat 306 is accommodated in the second accommodating cavity. The second hook 307 is connected to the second ball seat 306 and is connected to the first elastic member 303. When the shampoo cover 2 rotates relative to the mounting seat 1, the second ball seat 306 rotates relative to the second connecting seat 201 with its center as the axis. Because the second rotating seat 302 has the second ball seat 306, the second ball seat 306 rotates relative to the second connecting seat 201 with its center as the axis when the shampoo cover 2 rotates relative to the mounting seat 1. This allows the second rotating seat 302 to rotate smoothly and provide excellent adaptability.

[0034] In the embodiment of the present invention, the first elastic member 303 is a rubber band with one end hung on the first rotating base 301 and the other end hung on the second rotating base 302 , and there are a plurality of rubber bands.

[0035] In this embodiment of the present invention, there are multiple buffer assemblies 3, spaced apart in the rotational direction of the shampoo hood 2. Specifically, there are two buffer assemblies 3. This ensures that the pulling force acting on the shampoo hood 2 is evenly distributed, resulting in a gentle and comfortable rubbing effect on the user's head, similar to manual rubbing, providing a pleasant user experience.

[0036] In an embodiment of the present invention, a first drive assembly 4 is further included. The first drive assembly 4 includes a first motor 401 provided on the mounting base 1 and a turntable 402 connected to the output shaft of the first motor 401. The shampooing hood 2 is connected to the turntable 402. The connection between the shampooing hood 2 and the turntable 402 deviates from the axis of the output shaft of the first motor 401. The shampooing hood 2 is driven by the first drive assembly 4 and rotates relative to the mounting base 1 with the connection between the turntable 402 and the output shaft of the first motor 401 as the axis. The shampooing hood 2 is connected to the turntable 402 through a connecting rod 5. The axis of the connecting rod 5 is parallel to the axis of the shampooing hood 2. The axis of the output shaft of the first motor 401 is parallel to the axis of the turntable 402. The connecting rod 5 is tilted inward so that its axis forms an angle θ with the axis of the turntable 402, where θ is an acute angle. Since the connection between the shampoo hood 2 and the turntable 402 deviates from the axis of the output shaft of the first motor 401, the connecting rod 5 is tilted inward so that its axis forms an angle θ with the axis of the turntable 402. The shampoo hood 2 rotates relative to the mounting base 1 with the connection between the turntable 402 and the output shaft of the first motor 401 as the axis, so that the shampoo hood 2 covers the user's head at a certain angle, that is, the shampoo hood 2 rubs the user's head at a certain angle, so that the force exerted by the shampoo hood 2 on the user's head is closer to manual rubbing, and the user experience is good.

[0037] In this embodiment of the present invention, the line L connecting the first and second rotating bases 301, 302 forms an acute angle α with the axis of the connecting rod 5. Because the angle α is formed between the line L connecting the first and second rotating bases 301, 302 and the axis of the connecting rod 5, the traction force exerted by the first elastic member 303 on the shampooing hood 2 when the shampooing hood 2 rotates relative to the mounting base 1 forms an angle with the rotational direction of the shampooing hood 2. This results in a force on the user's head that is closer to that of manual kneading, providing a better user experience.

[0038] In the embodiment of the present invention, the shampooing cover 2 has an open state and a closed state. The shampooing cover 2 includes a base 203 and a plurality of shampooing claws 204. The plurality of shampooing claws 204 are sequentially arranged in the circumferential direction of the base 203 and are respectively hinged to the base 203. The plurality of shampooing claws 204 can rotate about the hinged joints with the base 203 to switch the shampooing cover 2 between the open state and the closed state. In the closed state, any shampooing claw 204 is abutted against the adjacent shampooing claws 204, so that the plurality of shampooing claws 204 are enclosed to form a shampooing chamber 205; in the open state, any shampooing claw 204 is separated from the adjacent shampooing claws 204. The shampooing claws 204 have inner walls 206. When the shampooing claws 204 are combined to form a shampooing chamber 205, the inner walls 206 form the walls of the shampooing chamber 205. At least some of the shampooing claws 204 have massage rods 207 on the inner walls 206. The massage rods 207 extend from the inner walls 206 toward the geometric center of the shampooing chamber 205. Since the shampooing cover 2 can be opened and closed, it is convenient for the shampooing cover 2 to surround and massage the user's head.

[0039] In this embodiment of the present invention, the base 203 has a third accommodating cavity 208, within which a second drive assembly 209 and a third drive assembly 210 are disposed. The shampooing claw 204 has a rotating lever 211. One longitudinal end of the shampooing claw 204 is fixedly connected to the shampooing claw 204, while the other longitudinal end extends into the third accommodating cavity 208. The longitudinal middle portion is hinged to the base 203.

[0040] The second drive assembly 209 is used to push against the end of the toggle lever 211 extending into the third accommodating chamber 208, causing the toggle lever 211 to rotate about its hinged connection with the base 203, thereby driving the shampooing claws 204 to rotate and switch the shampooing cover 2 from the closed state to the open state. Specifically, the second drive assembly 209 includes a second motor 212, a screw rod 213, and a push plate 214. The second motor 212 is fixedly connected to the third accommodating chamber 208, the screw rod 213 is transmission-connected to the output shaft of the second motor 212, and the push plate 214 is slidably connected to the screw rod 213 to push against the end of the toggle lever 211 extending into the third accommodating chamber 208, causing the toggle lever 211 to rotate about its hinged connection with the base 203, thereby driving the shampooing claws 204 to rotate and switch the shampooing cover 2 from the closed state to the open state. Since the second driving assembly 209 adopts a screw wheel structure, the push plate 214 pushes the end of the dial rod 211 extending into the third accommodating chamber 208, so that the multiple shampooing claws 204 are synchronously turned outward to realize the opening of the shampooing cover 2, which has the advantages of simple structure and stable driving.

[0041] The third driving assembly 210 is used to push against the end of the toggle lever 211 extending into the third accommodating chamber 208, causing the toggle lever 211 to rotate about its hinged connection with the base 203, thereby driving the shampooing claw 204 to rotate and switch the shampooing cover 2 from the open state to the closed state. Specifically, the third driving assembly 210 includes a first connecting member 215, a second connecting member 216, and a second elastic member 217. The first connecting member 215 is fixed to the base 203, the second connecting member 216 is fixed to the end of the toggle lever 211 extending into the third accommodating chamber 208, and one end of the second elastic member 217 is connected to the first connecting member 215 and the other end to the second connecting member 216. The direction of the first connecting member 215 toward the second connecting member 216 is defined as the first direction. When the second driving assembly 209 switches the shampooing cover 2 to the open state, the second elastic member 217 is elastically compressed, causing the toggle lever 211 to have a tendency to flip in the first direction, causing the shampooing cover 2 to switch to the closed state. Because the third drive assembly 210 utilizes an elastic compression drive structure, the second elastic member 217 drives the plurality of shampooing claws 204 inwardly when the toggle lever 211 disengages the push plate 214, thereby closing the shampooing cover 2. This provides advantages of a simple structure and stable drive. Furthermore, because the third drive assembly 210 utilizes an elastic compression drive structure, the plurality of shampooing claws 204 automatically adapt to the user's head when they are inwardly rotated to cover the user's head.

[0042] In this embodiment of the present invention, the base 203 has a toggle slot 218, and the toggle lever 211 is hinged within the toggle slot 218 and extends from the toggle slot 218 into the third accommodating chamber 208. When the shampooing hood 2 is switched to the closed state, the toggle lever 211 abuts against the first side wall 219 of the toggle slot 218. When the shampooing hood 2 is switched to the open state, the toggle lever 211 abuts against the second side wall 220 of the toggle slot 218. The first side wall 219 and the second side wall 220 are disposed opposite each other. Because the base 203 has the toggle slot 218 and the toggle lever 211 is hinged within the toggle slot 218 and extends from the toggle slot 218 into the third accommodating chamber 208, when the shampooing hood 2 is switched to the closed state or the open state, the toggle lever 211 abuts against the wall of the toggle slot 218, thereby limiting the rotation range of the toggle lever 211 and ensuring precise operation.

[0043] It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information. In addition, the terms "center of a circle", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.
