Description

Technical Field

[0001] This invention relates to the field of shampoo machine technology that is easy to position, and more specifically, to a shampoo machine that is easy to position. Background Technology

[0002] Dust in the air mixes with oil secreted by the scalp's sebaceous glands and adheres to the hair. The hair cuticle produces dandruff due to metabolism. This dirt and dandruff can cause itching and affect appearance. Therefore, washing hair is an essential part of our daily hair cleaning routine. Shampoo machines replace manual washing, providing a cleaner and more hygienic experience. Automated and easily positioned shampoo machines are suitable for salons, beauty parlors, nursing homes, hospitals, and other places where manual washing is inconvenient. They offer healthy hair washing, prevent infection, and solve labor shortages.

[0003] Existing easy-to-position shampoo machines can cause uneven washing because of differences in body shape and posture. This can result in the user's head being positioned incorrectly after being placed into the machine. Furthermore, the washing mechanism of these machines is fixed, leading to uneven washing.

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0035] Example:

[0036] See Figures 1 to 3This invention discloses a shampoo machine with easy positioning, comprising a bed 100 and a washing structure 400. The bed 100 is provided with a face basin 200 and shoulder positioning blocks 300 for positioning the user's body. The washing structure 400 includes a drive assembly 420 and a washing assembly 410. The drive assembly 420 can move the washing assembly 410 above the face basin 200 to wash the user's head.

[0037] The shampoo machine disclosed in this embodiment is equipped with a sliding shoulder positioning block 300. Before cleaning the head, the user first puts the head into the wash basin 200 and rests the shoulders against the shoulder positioning block 300. Then, by moving the shoulder positioning block 300, the head of each user is placed exactly within the working range of the washing structure 400. This ensures that when the washing structure 400 is used to clean the user's head, it can be cleaned more thoroughly and evenly.

[0038] See Figure 1 The shoulder positioning block 300, the face basin 200, and the cleaning structure 400 are arranged sequentially along the length of the bed body 100. The cleaning structure 400 includes a drive assembly 420 and a cleaning assembly 410. The bed body 100 includes a first table 110 and a second table 120, which are arranged along the length of the bed body 100, with the first table 110 being higher than the second table 120. The face basin 200 is installed on the second table 120.

[0039] See Figure 2The cleaning assembly 410 includes a sliding plate 411, a first connecting rod 412, a second connecting rod 413, a mounting plate 414, and a cleaning head 415. The sliding plate 411 is slidably connected to the bed 100, and the direction of movement of the sliding plate 411 is parallel to the length direction of the bed 100. The first connecting rod 412 is rotatably connected to the sliding plate 411, one end of the second connecting rod 413 is rotatably connected to the first connecting rod 412, and the other end of the second connecting rod 413 is rotatably connected to the bed 100. The rotation axes of the first connecting rod 412 and the second connecting rod 413 are parallel to each other, and their rotation axes are both parallel to the bed 100 and arranged along the width direction of the bed 100. Mounting plate 414 is mounted on second connecting rod 413 and is located at sink 200. Washing head 415 is mounted on mounting plate 414. Drive assembly 420 is used to drive slide plate 411 to move closer to or further away from sink 200. When slide plate 411 moves, it drives washing head 415 to move back and forth along an arc above sink 200 via first connecting rod 412 and second connecting rod 413 to wash user's head. Drive assembly 420 is mounted on first tabletop 110. The end of second connecting rod 413 opposite to first connecting rod 412 is rotatably connected to second tabletop 120. This allows first connecting rod 412 to be higher than second connecting rod 413, so that when second connecting rod 413 drives mounting plate 414 and washing head 415 to move, it can better conform to the contour of user's head.

[0040] The mounting plate 414 is arc-shaped, with its inner side facing the washbasin 200. Multiple cleaning heads 415 are provided, each mounted on the inner side of the washbasin 200 and slidably connected to the mounting plate 414. The cleaning heads 415 can move radially along the mounting plate 414. Since everyone's head size is different, adjusting the position of each cleaning head 415 can accommodate different head sizes, ensuring good contact between the cleaning head 415 and the user's head without causing excessive pressure, thus guaranteeing effective cleaning.

[0041] The cleaning head 415 can be connected to the mounting plate 414 by bolts. The bolts can be arranged radially along the mounting plate 414, and the cleaning head 415 can be moved radially along the mounting plate 414 by tightening the bolts. Of course, using bolts to connect and control the cleaning head 415 is only one implementation method in this embodiment, and other connection methods are also possible in other embodiments.

[0042] The drive assembly 420 includes a motor 421, a lead screw 422, a first contact switch 423, a second contact switch 424, and a safety switch.

[0043] Motor 421 is mounted on bed 100 and is driven by lead screw 422. Lead screw 422 is rotatably connected to bed 100 and is arranged along the length of bed 100. Slide plate 411 is threadedly connected to lead screw 422. First contact switch 423 and second contact switch 424 are spaced apart along the length of lead screw 422, located on opposite sides of slide plate 411, and both are located on the moving path of slide plate 411, so that slide plate 411 can trigger first contact switch 423 or second contact switch 424 respectively when moving. First contact switch 423 and second contact switch 424 are both electrically connected to motor 421, and triggering first contact switch 423 or second contact switch 424 will change the rotation direction of motor 421.

[0044] The safety switch is electrically connected to the motor 421. When the safety switch is on, the motor 421 can be energized normally and will operate normally. When the safety switch is off, the motor 421 cannot be energized; that is, even if the start switch for the motor 421 is turned on, the motor 421 will not operate. The safety switch works in conjunction with the head positioning structure 600 to prevent accidental activation of the motor 421 during user position adjustments, thereby preventing accidental injury to the user during position adjustments caused by the cleaning structure 400 operating.

[0045] See Figure 1 The face basin 200 is positioned in front of the washing structure 400, and the shoulder positioning block 300 is positioned in front of the face basin 200. During use, the user's shoulder is always against the shoulder positioning block 300 to ensure that the user's position is always in the correct position, thereby facilitating the washing structure 400 to wash the user's head.

[0046] A forehead support 500 is installed inside the washbasin 200. The forehead support 500 is slidably connected to the washbasin 200 and can move along the height direction of the washbasin 200. By adjusting the forehead support 500 up and down and adjusting each washing head 415, it can be ensured that the predetermined area can be cleaned when each washing head 415 moves.

[0047] See Figure 1 and Figures 3 to 9 A head positioning structure 600 is also provided in the sink 200. The head positioning structure 600 can control the position of the user's head in the sink 200. It works in conjunction with the shoulder positioning block 300 to better confirm the position of the user's head, thereby improving the washing effect.

[0048] Specifically, referring to 1 and 3, the shoulder positioning block 300 is slidably connected to the bed 100, and the shoulder positioning block 300 can move closer to or further away from the face pool 200 along the length direction of the bed 100. The head positioning structure 600 includes a head positioning plate 610, a connecting frame 620, a first control rod 650, a second control rod 630, a friction block 640, and an elastic element.

[0049] The connecting frame 620 slides with the face basin 200, and the connecting frame 620 can move along the height direction of the face basin 200. The head positioning plate 610 is installed on the top of the connecting frame 620 and is located inside the face basin 200. When the connecting frame 620 drives the head positioning plate 610 to rise, the height of the head positioning plate 610 will exceed the forehead support 500. At this time, the user only needs to move forward and make the top of their head contact the head positioning plate 610, and then move the shoulder positioning block 300 until it just contacts their shoulder to complete the positioning. After positioning, the connecting frame 620 drives the head positioning plate 610 to move downward. At this time, the height of the head positioning plate 610 will be lower than the forehead support 500, so as to avoid the head positioning plate 610 affecting the operation of the washing structure 400.

[0050] A first limiting part 621 is provided on the connecting frame 620. A limiting block 700 and a second elastic member are provided below the bed body 100. The limiting block 700 is slidably engaged with the bed body 100, and the sliding direction of the limiting block 700 is parallel to the sliding direction of the shoulder positioning block 300. A second limiting part 710 is provided on the limiting block 700 for engaging with the first limiting part 621. The second limiting part 710 engages with the first limiting part 621 to fix the head positioning structure 600. The two ends of the second elastic member are respectively connected to the bed body 100 and the limiting block 700, indicating that the second elastic member causes the limiting block 700 to tend to move towards the head positioning structure 600. When the connecting frame 620 lifts the head positioning plate 610 and makes the head positioning plate 610 higher than the forehead support frame 500, the limiting block 700, under the elastic force of the second elastic member, drives the second limiting part 710 to press tightly against the bottom of the connecting frame 620; after positioning is completed, when the connecting frame 620 moves the head positioning plate 610 downward, the first limiting part 621 on the connecting frame 620 and the second limiting part 710 on the limiting block 700 cooperate to make the limiting block 700 overcome the elastic force of the second elastic member and move backward, thereby allowing the head positioning plate 610 to press tightly against the forehead support frame 500. When the first limiting part 621 moves below the second limiting part 710, the limiting block 700 moves again under the elastic force of the second elastic member until it is close to the connecting frame 620. However, at this time, the second limiting part 710 is located above the first limiting part 621. By using the restriction of the first limiting part 621 by the second limiting part 710, the connecting frame 620 can be restricted, preventing the connecting frame 620 from driving the head positioning plate 610 to move upward again, thereby avoiding affecting the operation of the cleaning structure 400.

[0051] Specifically, the top of the first limiting part 621 can be set as a flat surface, and the bottom of the first limiting part 621 can be set as a slope. Then, the top of the second limiting part 710 can be set as a slope, and the bottom of the second limiting part 710 can be set as a flat surface. In this way, when the first limiting part 621 is below the second limiting part 710, the flat surface of the bottom of the second limiting part 710 can cooperate with the flat surface of the top of the first limiting part 621 to restrict the first limiting part 621. When the first limiting part 621 is above the second limiting part 710 and it is necessary to push the first limiting part 621 downward, the slope of the bottom of the first limiting part 621 can cooperate with the slope of the top of the second limiting part 710 to push the second limiting part 710 and the limiting block 700 to move backward against the elastic force of the second elastic member.

[0052] The first end of the limiting block 700 extends to engage with the connecting frame 620, and the second end of the limiting block 700 extends below the shoulder positioning block 300. Both the first and second ends of the limiting block 700 are slidably connected to the bed frame 100. This makes the limiting block 700 more stable and facilitates the installation of the second elastic element. When the shoulder positioning block 300 needs to be repositioned, simply push the limiting block 700 to release the restriction of the second limiting part 710 on the first limiting part 621. At this time, the connecting frame 620 can drive the head positioning plate 610 to move upward.

[0053] The shoulder positioning block 300 has an extension 310 at its bottom, which extends along the length of the bed 100 and extends below the head positioning structure 600. A first control lever 650 is mounted on the bottom of the connecting frame 620, and a second control lever 630 is slidably engaged with the first control lever 650, with the second control lever 630 positioned towards the extension 310 of the shoulder positioning block 300. A friction block 640 is mounted on one end of the second control lever 630 facing the shoulder positioning block 300. Two ends of a first elastic member 660 are connected to the first control lever 650 and the second control lever 630, respectively, and the first elastic member 660 causes the second control lever 630 to tend to move towards the extension 310 of the shoulder positioning block 300. When the connecting frame 620 moves the head positioning plate 610 upward, the connecting frame 620 will simultaneously move the first control rod 650 and the second control rod 630 upward. At this time, the friction block 640 is basically separated from the extension 310 of the shoulder positioning block 300, and the shoulder positioning block 300 can move freely along the length of the bed 100. When the connecting frame 620 descends to the lowest position, the second control block moves the friction block 640 to abut against the extension 310 of the shoulder positioning block 300. The huge friction between the friction block 640 and the extension 310 of the shoulder positioning block 300 can be used to fix the shoulder positioning block 300.

[0054] Furthermore, in this embodiment, the safety switch is installed below the bed body 100 and below the head positioning structure 600. When the connecting frame 620 moves downward and causes the second limiting part 710 to restrict the first limiting part 621, the connecting frame 620 can just turn on the safety switch; when the connecting frame 620 drives the head positioning plate 610 to a position higher than the forehead support 500, the connecting frame 620 turns off the safety switch, at which time the motor 421 cannot start, thereby ensuring that the user's position can be adjusted in a safe environment.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
