Description
Technical Field
[0001] This utility model relates to the field of hair washing and care technology, and in particular to a flip-up cover structure. Background Technology
[0002] Head therapy, as a relaxation and wellness method, is becoming increasingly popular among consumers. Existing head therapy basins typically come with a head cover, which is used to close and cover the head during specific therapeutic processes (such as steaming or heating) to create a sealed environment and enhance the therapeutic effect. After use, the cover is opened without obstructing head movement. However, the head cover of existing head therapy basins requires manual opening and closing, which is inconvenient, especially when the user is lying down. Those skilled in the art desire a flip-up structure that allows the head cover to open and close automatically. Utility Model Content
[0003] The main purpose of this invention is to propose a flip-up hood structure, which aims to solve the technical problem that the hood in the prior art needs to be opened and closed manually, which is inconvenient to operate.
[0004] To achieve the above objectives, this utility model proposes a flip-up structure, comprising:
[0005] A basin body, wherein the basin body is provided with a care tank for care;
[0006] A cover body is provided on the upper rear side of the nursing tank. The cover body includes cover side plates located on the left and right sides. The nursing tank is located between the two cover side plates. The cover side plates are rotatably connected to the basin body.
[0007] The flipping drive mechanism includes a drive motor and a transmission shaft. The drive motor is fixed relative to the basin body and is located between the two cover side plates. The transmission shaft is fixedly connected to the cover side plates and is drively connected to the drive motor. The drive motor can drive the cover body to rotate forward to close to the upper side of the nursing groove or rotate backward to open the nursing groove.
[0008] The drive motor drives the cover to rotate via the transmission shaft, which can automatically rotate the cover forward to close it to the top of the nursing tank or rotate it backward to open the nursing tank. This eliminates the need for manual opening and closing, making operation more convenient. The drive motor is located between the two side plates of the cover, which can effectively utilize the space of the left and right width of the basin and the cover, making the equipment space more compact.
[0009] Preferably, there are two drive shafts, which are fixedly connected to the two side plates of the cover, respectively. The drive motor is located between the two drive shafts, and output shafts are provided on both the left and right sides of the drive motor. The two drive shafts are fixedly connected to the two output shafts respectively.
[0010] The drive motor drives the two sides of the cover to rotate via transmission shafts located on both sides, ensuring more even force distribution on the cover and effectively avoiding twisting or uneven stress that may occur with single-axis drive, thus guaranteeing the synchronicity and stability of the cover's rotation. The use of a dual-output shaft drive motor positioned between the two transmission shafts allows for a more compact structure.
[0011] Preferably, the flipping drive mechanism further includes a position sensor and a sensing block. The position sensor is fixed relative to the drive motor, the sensing block is fixedly connected to the transmission shaft, the sensing block is positioned to match the position sensor, and the position sensor is signal-connected to the drive motor.
[0012] The position of the positioning sensor can be set to correspond to the position where the cover is closed and / or opened. When the drive motor rotates the cover to the position where it is closed and / or opened, the positioning sensor detects the sensing block, and the drive motor stops driving, improving the accuracy of the cover's positioning and preventing the cover from rotating in the wrong position or rotating too much, which could cause an impact.
[0013] Preferably, a first clamping ring and a second clamping ring are sleeved on the drive shaft, and the first clamping ring or the second clamping ring is fixedly connected to the drive shaft. The cover side plate is disposed between the first clamping ring and the second clamping ring, the first clamping ring is disposed on the outside of the cover side plate, the first clamping ring is provided with a first clamping through hole, the second clamping ring is provided with a second clamping screw hole, and the cover side plate is provided with a third clamping through hole. The first clamping through hole, the third clamping through hole and the second clamping screw hole are arranged opposite each other. The flipping drive mechanism also includes a clamping screw, which passes through the first clamping through hole and the third clamping through hole and is threadedly connected to the second clamping screw hole.
[0014] By passing the clamping screw through the first clamping through hole of the first clamping ring and the third clamping through hole of the cover, and locking it with the second clamping screw hole of the second clamping ring, the first and second clamping rings can clamp and fix the cover side plate, increasing the contact surface with the cover and avoiding loosening or damage caused by insufficient strength when directly drilling threads on the cover. This achieves an effective fixed connection of the cover. At the same time, the clamping screw can also drive the cover to rotate through the third clamping through hole, enhancing the overall stability, torsional resistance and reliability of the connection.
[0015] Preferably, the basin body is provided with a support hole, and the second clamping ring passes through the support hole, and the second clamping ring is rotatably connected to the support hole. The rotatable connection between the cover side plate and the basin body is achieved through the rotatable connection of the second clamping ring and the support hole, resulting in a relatively simple structure.
[0016] Preferably, a decorative cover is provided on the outer side of the first clamping ring, which covers the first clamping ring and the clamping screw. The decorative cover can cover the first clamping ring and the clamping screw, improving the aesthetics.
[0017] Preferably, a counterweight is fixedly connected to the drive shaft, and the center of gravity of the counterweight and the center of gravity of the cover are respectively located on the radial sides of the drive shaft.
[0018] The counterweight effectively balances the gravitational torque generated by the weight of the enclosure itself by shifting the system's center of gravity and generating a balancing torque. This significantly reduces the torque that the drive motor needs to overcome when rotating the enclosure, compensating for any potential torque deficiency in the drive motor and allowing the use of a relatively smaller drive motor. Simultaneously, the counterweight improves the smoothness of the enclosure's rotation, reduces system vibration, helps extend the lifespan of the drive motor, and enhances response speed.
[0019] Preferably, the drive motor is located on the outer side of the rear side of the nursing tank, and the basin body also includes a baffle plate, which is located on the rear side of the nursing tank and on the upper side of the drive motor.
[0020] The drive motor and its related transmission components are installed on the outside of the nursing tank and the bottom of the baffle. The rear side wall of the nursing tank and the baffle can isolate the drive motor from the space inside the nursing tank, effectively avoiding the risk of liquid splashing, water mist erosion or external water flow scouring, greatly reducing the probability of components getting damp and corroded, ensuring the long-term stable operation of the equipment, extending its service life and improving safety.
[0021] Preferably, the drive motor is a stepper motor. Due to the characteristics of stepper motors, the cover can be rotated manually, improving the flexibility of the equipment and the ease of operation for users in special circumstances. Attached Figure Description

[0035] like Figures 1 to 7 As shown, a flip-cover structure includes a basin 1, a cover 2, and a flipping drive mechanism.
[0036] The basin 1 is equipped with a care tank 11 for care, and the person's body is placed on the care tank 11 with the head on the back side for care.
[0037] The cover 2 is located on the upper rear side of the nursing tank 11. The cover 2 includes cover side plates 21 located on the left and right sides. The nursing tank 11 is located between the two cover side plates 21. The cover side plates 21 are rotatably connected to the basin 1.
[0038] The flipping drive mechanism includes a drive motor 31 and a transmission shaft 32. The drive motor 31 is fixed relative to the basin 1 and is located between the two cover side plates 21. The transmission shaft 32 is fixedly connected to the cover side plate 21 and is connected to the transmission shaft 32. The drive motor 31 can drive the cover 2 to rotate forward to close to the upper side of the nursing tank 11 or rotate backward to open the nursing tank 11.
[0039] The drive motor 31 drives the cover 2 to rotate via the transmission shaft 32, enabling the cover 2 to automatically rotate forward and close to the upper side of the nursing tank 11. (Refer to...) Figure 2 Or rotate backward to open the nursing tank 11, as shown in the following figure. Figure 1 It eliminates the need for manual opening and closing, making operation more convenient; the drive motor 31 is located between the two side plates 21 of the cover 2, which can effectively utilize the space of the left and right widths of the basin 1 and the cover 2, making the equipment space more compact.
[0040] In some specific embodiments, reference is made to Figure 4 There are two drive shafts 32, which are fixedly connected to two side plates 21 respectively. The drive motor 31 is located between the two drive shafts 32. The drive motor 31 has output shafts on both the left and right sides, and the two drive shafts 32 are fixedly connected to the two output shafts respectively.
[0041] The drive motor 31 drives the two sides of the cover 2 to rotate via the transmission shafts 32 located on both sides, so that the cover 2 is subjected to more force and effectively avoids the twisting or uneven stress that may be caused by single-axis drive, ensuring the synchronicity and stability of the cover 2's rotation. The drive motor 31 with dual output shafts is set between the two transmission shafts 32, which makes the structure more compact. Preferably, the output shafts are connected to the corresponding transmission shafts 32 via couplings.
[0042] In some specific embodiments, the flipping drive mechanism further includes a position sensor 33 and a sensing block 34. The position sensor 33 is fixed relative to the drive motor 31, the sensing block 34 is fixedly connected to the transmission shaft 32, the sensing block 34 and the position sensor 33 are matched and set, and the position sensor 33 is signal connected to the drive motor 31.
[0043] The position of the positioning sensor 33 can be set to correspond to the position where the cover 2 is closed and / or fully opened. When the drive motor 31 rotates the cover 2 to the position where it is closed and / or fully opened, the positioning sensor 33 senses the sensing block 34, and the drive motor 31 stops driving, improving the accuracy of the cover 2's positioning and preventing the cover 2 from rotating out of position or rotating too much, thus avoiding impact. The positioning sensor can be a photoelectric, magnetic, or mechanical sensor, etc.
[0044] In some specific embodiments, reference is made to Figure 7 A first clamping ring 35 and a second clamping ring 36 are fitted on the drive shaft 32. The first clamping ring 35 or the second clamping ring 36 is fixedly connected to the drive shaft 32. The cover side plate 21 is located between the first clamping ring 35 and the second clamping ring 36. The first clamping ring 35 is located on the outside of the cover side plate 21. The first clamping ring 35 is provided with a first clamping through hole 351. The second clamping ring 36 is provided with a second clamping screw hole 361. The cover side plate 21 is provided with a third clamping through hole 211. The first clamping through hole 351, the third clamping through hole 211 and the second clamping screw hole 361 are arranged opposite each other. The flipping drive mechanism also includes a clamping screw 37. The clamping screw 37 passes through the first clamping through hole 351 and the third clamping through hole 211 and is threadedly connected to the second clamping screw hole 361.
[0045] By passing the clamping screw 37 through the first clamping through hole 351 of the first clamping ring 35 and the third clamping through hole 211 of the cover 2, and locking it with the second clamping screw hole 361 of the second clamping ring 36, the first clamping ring 35 and the second clamping ring 36 can clamp and fix the cover side plate 21, increasing the contact surface with the cover 2 and avoiding loosening or damage caused by insufficient strength when directly drilling threads on the cover 2. This achieves an effective fixed connection of the cover 2. At the same time, the clamping screw 37 can also drive the cover 2 to rotate through the third clamping through hole 211, enhancing the overall stability, torsional resistance and reliability of the connection. Preferably, the first clamping ring 35 can be locked and fixed with the drive shaft 32 by a radially arranged locking screw.
[0046] Furthermore, the basin body 1 is provided with a support hole (not shown in the attached figure), and the second clamping ring 36 passes through the support hole and is rotatably connected to the support hole. The rotatable connection between the cover side plate 21 and the basin body 1 is achieved by the second clamping ring 36 and the support hole, which is a relatively simple structure.
[0047] Furthermore, a decorative cover 38 is provided on the outer side of the first clamping ring 35, which covers the first clamping ring 35 and the clamping screw 37. The decorative cover 38 can cover the first clamping ring 35 and the clamping screw 37, improving the aesthetics. Preferably, the decorative cover 38 can be interference-fitted onto the outer periphery of the first clamping ring 35 for fixation.
[0048] In some specific embodiments, a counterweight 39 is fixedly connected to the drive shaft 32, and the center of gravity of the counterweight 39 and the center of gravity of the cover 2 are respectively located on the radial sides of the drive shaft 32. When the cover 2 closes forward, refer to... Figure 6 The counterweight rotates upwards at the rear; when cover 2 opens backwards, refer to... Figure 5 The counterweight rotates downwards at the rear.
[0049] The counterweight 39 effectively balances the gravitational torque generated by the weight of the cover 2 itself by changing the system's center of gravity and generating a balancing torque. This significantly reduces the torque that the drive motor 31 needs to overcome when it rotates the cover 2, compensating for any potential torque deficiency in the drive motor 31 and allowing the use of a relatively smaller drive motor 31. Simultaneously, the counterweight 39 also improves the smoothness of the cover 2's rotational movement, reduces system vibration, helps extend the lifespan of the drive motor 31, and improves response speed.
[0050] In some specific embodiments, the drive motor 31 is located on the outer side of the rear side of the nursing tank 11, and the basin body 1 also includes a baffle plate 12, which is located on the rear side of the nursing tank 11 and on the upper side of the drive motor 31.
[0051] The drive motor 31 and its related transmission components are installed on the outside of the nursing tank 11 and the lower side of the baffle plate 12. The rear side wall of the nursing tank 11 and the baffle plate 12 can isolate the drive motor 31 from the space inside the nursing tank 11, effectively avoiding the risk of liquid splashing, water mist erosion or external water flow scouring, greatly reducing the probability of components getting damp and corroded, ensuring the long-term stable operation of the equipment, extending its service life and improving safety.
[0052] In some specific embodiments, the drive motor 31 is a stepper motor. Due to the characteristics of stepper motors, the cover 2 can also be rotated manually, which improves the flexibility of the equipment and the ease of operation for users in special situations.
[0053] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
