Description

Technical Field

[0001] The utility model relates to the technical field of beauty equipment, in particular to a power transmission mechanism and a microcrystal handle device for a beauty instrument. Background Art

[0002] Microcrystalline hydration device is a commonly used beauty device. Its principle is to use the extremely fine needles on the microcrystalline head to penetrate the stratum corneum on the surface of the human body, open corresponding channels on the epidermis without damaging the epidermis of the skin, and allow the active ingredients of the nutrient solution to effectively penetrate the skin, thereby promoting the skin's absorption of the beauty solution to achieve skin repair, whitening, tightening, wrinkle reduction and other effects.

[0003] In this type of device, the movement of the microcrystal head is usually achieved by utilizing a power transmission mechanism to drive the microcrystal head to vibrate, and the microcrystal head moves rapidly back and forth relative to the epidermis of the skin. In the currently common devices of this type, the power transmission mechanism used is generally a cam mechanism, which uses the movement of the cam mechanism to drive the microcrystal head to vibrate rapidly back and forth. However, in actual applications, since the cam in the cam mechanism needs to be in continuous dynamic contact with the telescopic component used for its power transmission (that is, the telescopic component is driven to perform linear telescopic movement through the rotation of the cam), after long-term use, it is easy to cause wear inside the power transmission mechanism and affect the normal operation of the device, resulting in a short service life of the beauty device; at the same time, due to the continuous friction between the cam and the telescopic component, the beauty device will also generate a lot of noise during use, which is easy to bring a bad user experience. Utility Model Content

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a power transmission mechanism for a beauty instrument, which can effectively reduce wear inside the power transmission mechanism and also reduce noise during use of the beauty device.

[0005] Another object of the present invention is to provide a microcrystal handle device having the above-mentioned power transmission mechanism.

[0006] The technical solution of the present utility model is as follows: A power transmission mechanism for a beauty instrument, comprising a power driving member, an inclined shaft member, a bearing, a swinging member, a first telescopic guide rod, a second telescopic guide rod and a sliding assembly. The middle part of the inclined shaft member is an inclined shaft hole, and the power output shaft of the power driving member is connected to the shaft hole of the inclined shaft member. The outer periphery of the inclined shaft member is connected to the swinging member through a bearing. The first telescopic guide rod and the second telescopic guide rod are respectively arranged in the sliding assembly. One end of the first telescopic guide rod extends out of the sliding assembly and is connected to the swinging member, and one end of the second telescopic guide rod extends out of the sliding assembly and is connected to the movable seat of the end consumable of the beauty instrument. During use, the power driving member provides power to drive the inclined shaft member to rotate. Since the shaft hole of the inclined shaft member is inclined, under the action of the bearing, it will drive the swinging member to swing back and forth along the axis direction, thereby pushing the first telescopic guide rod and the second telescopic guide rod to move back and forth along the sliding assembly, and finally driving the movable seat and the end consumable of the beauty instrument to perform rapid back-and-forth movement, so as to form a vibrating effect on the skin epidermis layer.

[0007] The sliding assembly includes a matching slide base and a slider. A channel for the slider to slide is provided in the slide base. The first telescopic guide rod and the second telescopic guide rod are respectively fixedly installed on the slider. One end of the first telescopic guide rod extends out from one side of the slide base and is connected to the swinging member. The other end of the first telescopic guide rod is located in the channel of the slide base. One end of the second telescopic guide rod extends out from the other side of the slide base and is connected to the movable seat of the end consumable of the beauty instrument. The other end of the second telescopic guide rod is located in the channel of the slide base. Among them, both the first telescopic guide rod and the second telescopic guide rod are fixedly connected to the slider, and the three move back and forth together. The first telescopic guide rod follows the movement during the back-and-forth swing of the swinging member, driving the slider to slide along the channel in the slide base. The second telescopic guide rod follows the movement of the slider and transmits the power to the movable seat of the end consumable through its end.

[0008] In the channel of the slide base, a first compression spring is further provided between the slide base and the slider. The setting of the first compression spring can make the operation of the slider in the slide base more stable. At the same time, by using its elastic force, it can ensure that the first telescopic guide rod is always connected to the swinging member.

[0009] In the slide base, the channel is in the shape of a cylinder with a core in the center, and the slider is in the shape of a disc with a through hole in the middle. The through hole on the slider is matched with the core on the slide base. The first compression spring is sleeved on the core, and both ends of the first compression spring are respectively pressed against the slide base and the slider. Among them, when the slider drives the first telescopic guide rod and the second telescopic guide rod to slide in the channel, the cooperation between the through hole and the core forms a guiding part. The first compression spring can play a role in quickly resetting the slider, ensuring its stable operation, and at the same time making the first telescopic guide rod always connected to the swinging member.

[0010] One end of the power driving member is further provided with a fixing member. The inclined shaft member, the bearing and the swinging member are arranged inside the fixing member. The power output shaft of the power driving member passes through the fixing member and is connected to the inclined shaft member. One end of the fixing member is connected to the outer periphery of the sliding seat. Among them, the fixing member serves as the installation base for components such as the power driving member, the inclined shaft member, the bearing and the swinging member, and is fixedly connected to the sliding seat, which can make the entire power transmission mechanism form a stable connection structure.

[0011] The swinging member is integrally in the shape of a cylinder with a through hole in the middle. The bearing is connected to the inner wall of the swinging member. A guide groove is provided on one side of the swinging member facing the sliding assembly. One end of the first telescopic guide rod extends out of the sliding assembly and is inserted into the guide groove on the swinging member.

[0012] The power driving member is a motor.

[0013] One side of the movable seat is further provided with a consumable sleeve for installing the end consumable. A second compression spring is further provided on one side of the movable seat facing the consumable sleeve. The middle part on the other side of the movable seat is connected to the second telescopic guide rod. Among them, driven by the second telescopic guide rod, the movable seat will drive the consumable sleeve and the end consumable installed in the consumable sleeve to move synchronously and quickly. The second compression spring can play a role in quickly resetting the movable seat, ensuring its stable operation, and at the same time making the movable seat always connected to the second telescopic guide rod.

[0014] The end consumable of the beauty instrument is a microcrystalline head.

[0015] A microcrystalline handle device of the present utility model having the above power transmission mechanism includes a handle housing, a microcrystalline head, a consumable sleeve, a movable seat and a power transmission mechanism. The consumable sleeve, the movable seat and the power transmission mechanism are arranged inside the handle housing. The consumable sleeve is fixedly connected to the movable seat. The power output end of the power transmission mechanism is connected to the movable seat. The microcrystalline head is arranged at one end of the handle housing, and one end of the microcrystalline head is embedded and installed on the consumable sleeve.

[0016] After applying the above power transmission mechanism to the microcrystalline handle device, its principle is as follows: The power driving member provides power to drive the inclined shaft member to rotate. Since the shaft hole of the inclined shaft member is inclined, under the action of the bearing, it will drive the swinging member to swing back and forth along the axis direction, thereby pushing the first telescopic guide rod to move back and forth. Under the cooperation of the slider and the sliding seat, the second telescopic guide rod also follows to move back and forth. The end of the second telescopic guide rod pushes the movable seat to move. The movable seat drives the consumable sleeve and the microcrystalline head installed in the consumable sleeve to move synchronously and quickly, so as to form a vibrating effect on the skin epidermis layer.

[0017] The present utility model has the following beneficial effects compared with the prior art:

[0018] This power transmission mechanism utilizes an oblique shaft to convert the rotational motion of the power transmission mechanism into a linear swing of the rocking member, and then drives the end consumables of the beauty instrument (i.e., consumable components such as the microcrystalline head that need to move back and forth quickly) to vibrate rapidly through the cooperation of the first telescopic guide rod, the second telescopic guide rod, the sliding assembly and other components. There is no need for dynamic contact between the first telescopic guide rod and the rocking member in the power transmission mechanism, which can effectively reduce the wear inside the power transmission mechanism and reduce the noise during the use of the beauty equipment, thereby greatly improving the user experience.

[0019] The power transmission mechanism has a simple and compact structure. When applied to a microcrystal handle device, the power transmission is stable, the microcrystal handle device is light and easy to operate, and is convenient for wide-scale promotion and use in beauty equipment.

DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below with reference to the embodiments, but the embodiments of the present invention are not limited thereto.

[0027] Example

[0028] This embodiment provides a power transmission mechanism and a microcrystal handle device for a beauty instrument.

[0029] like Figures 1 to 3As shown in the figure, the power transmission mechanism includes a power driving member 1, an inclined shaft member 2, a bearing 3, a swing member 4, a first telescopic guide rod 5, a second telescopic guide rod 6 and a sliding assembly. The middle part of the inclined shaft member has an inclined shaft hole. The power output shaft of the power driving member is connected to the shaft hole of the inclined shaft member. The outer periphery of the inclined shaft member is connected to the swing member through a bearing. The first telescopic guide rod and the second telescopic guide rod are respectively arranged in the sliding assembly. One end of the first telescopic guide rod extends out of the sliding assembly and is connected to the swing member. One end of the second telescopic guide rod extends out of the sliding assembly and is connected to the movable seat 9 of the end consumable of the beauty instrument. During use, the power driving member provides power to drive the inclined shaft member to rotate. Since the shaft hole of the inclined shaft member is inclined, under the action of the bearing, it will drive the swing member to swing back and forth along the axis, thereby pushing the first telescopic guide rod and the second telescopic guide rod to move back and forth along the sliding assembly, and finally driving the movable seat and the end consumable of the beauty instrument to perform rapid back-and-forth movement, so as to form a vibrating effect on the skin epidermis layer.

[0030] Among them, the sliding assembly includes a matched sliding seat 7 and a slider 8. As Figure 2 shown, a channel 7-1 for the slider to slide is provided in the sliding seat. The first telescopic guide rod and the second telescopic guide rod are respectively fixedly installed on the slider. One end of the first telescopic guide rod extends out of one side of the sliding seat and is connected to the swing member. The other end of the first telescopic guide rod is located in the channel of the sliding seat. One end of the second telescopic guide rod extends out of the other side of the sliding seat and is connected to the movable seat 9 of the end consumable of the beauty instrument. The other end of the second telescopic guide rod is located in the channel of the sliding seat. Among them, the first telescopic guide rod and the second telescopic guide rod are both fixedly connected to the slider, and the three move back and forth together. The first telescopic guide rod follows the movement during the back-and-forth swing of the swing member, driving the slider to slide along the channel in the sliding seat. The second telescopic guide rod follows the movement of the slider and transmits power to the movable seat of the end consumable through its end. In the channel of the sliding seat, a first compression spring 10 is also provided between the sliding seat and the slider. The setting of the first compression spring can make the operation of the slider in the sliding seat more stable. At the same time, using its elastic force, it can ensure that the first telescopic guide rod is always connected to the swing member. In the sliding seat, the channel is in a cylindrical shape with a core 7-2 in the center. The slider is in a disc shape with a through hole 8-1 in the middle. The through hole on the slider is matched with the core on the sliding seat. The first compression spring is sleeved on the core, and both ends of the first compression spring are respectively pressed against the sliding seat and the slider. Among them, when the slider drives the first telescopic guide rod and the second telescopic guide rod to slide in the channel, the cooperation between the through hole and the core forms a guiding part. The first compression spring can play a role in quickly resetting the slider, ensuring its stable operation, and at the same time making the first telescopic guide rod always connected to the swing member.

[0031] A fixed member 11 is provided at one end of the power drive. The oblique shaft, bearing, and rocking member are housed within the fixed member. The power output shaft of the power drive passes through the fixed member and connects to the oblique shaft. One end of the fixed member is connected to the outer periphery of the slide. The fixed member serves as a mounting base for the power drive, the oblique shaft, the bearing, the rocking member, and other components, and is fixedly connected to the slide, forming a stable connection structure for the entire power transmission mechanism.

[0032] The rocking member is cylindrical in shape with a through hole in the middle, and the bearing is connected to the inner wall of the rocking member. Figure 3 As shown, a guide groove 4-1 is provided on the side of the rocking member facing the sliding assembly, and one end of the first telescopic guide rod extends out of the sliding assembly and is inserted into the guide groove on the rocking member.

[0033] In this embodiment, the power driving component is a motor.

[0034] One side of the movable base is equipped with a consumable sleeve 12 for mounting the terminal consumable. A second compression spring 13 is also installed on the side of the movable base facing the consumable sleeve. The middle portion of the other side of the movable base is connected to the second telescopic guide rod. Driven by the second telescopic guide rod, the movable base drives the consumable sleeve and the terminal consumable installed in the sleeve to move synchronously and rapidly. The second compression spring quickly resets the movable base, ensuring smooth operation and maintaining a constant connection between the movable base and the second telescopic guide rod. The terminal consumable of the beauty instrument is a microcrystalline head 14.

[0035] This embodiment also provides a microcrystalline handle device having the above-mentioned power transmission mechanism, such as Figure 4 As shown, it includes a handle shell 15, a microcrystal head 14, a consumable sleeve 12, a movable seat 9 and a power transmission mechanism. The consumable sleeve, the movable seat and the power transmission mechanism are arranged in the handle shell. The consumable sleeve is fixedly connected to the movable seat. The power output end of the power transmission mechanism is connected to the movable seat. The microcrystal head is arranged at one end of the handle shell, and one end of the microcrystal head is embedded and installed on the consumable sleeve. After the above-mentioned power transmission mechanism is applied to the microcrystal handle device, its principle is as follows: the power driving member provides power to drive the inclined shaft member to rotate. Since the shaft hole of the inclined shaft member is inclined, under the action of the bearing, it will drive the rocking member to swing back and forth along the axis direction, thereby pushing the first telescopic guide rod to move back and forth. Under the action of the slider and the sliding seat, the second telescopic guide rod also follows to move back and forth. The end of the second telescopic guide rod pushes the movable seat to move. The movable seat drives the consumable sleeve and the microcrystal head installed in the consumable sleeve to move synchronously and rapidly, thereby forming a vibration effect on the epidermis of the skin.
