Description

Technical Field

[0001] This invention relates to the field of beauty equipment technology, and in particular to a beauty handle and skin care device. Background Technology

[0002] Currently, many skin beauty devices on the market use a handpiece to apply various functional serums to the user's skin, then use technologies such as radio frequency or ultrasound to promote absorption, and finally initiate a cleansing process. During use, the handpiece typically needs to simultaneously supply the serum and collect any remaining waste liquid. However, the layout design of the supply and collection structures in existing beauty handpieces is not ideal, and the two structures can easily interfere with each other during operation, resulting in the inefficient collection of residual waste liquid that has not been absorbed by the skin. This not only reduces the waste liquid collection effect but also easily causes residual liquid to spread along the surface of the handpiece, increasing the risk of device contamination and affecting the user experience. Summary of the Invention

[0003] Therefore, it is necessary to address the problem that the liquid supply and recovery paths of some skin beauty device handles on the market are not designed reasonably, and the cleaned liquid is prone to splashing or flow deviation in open spaces, resulting in low waste liquid recovery efficiency. In this regard, a beauty handle and skin care device should be provided.

[0004] A beauty device handle includes: a mounting body having a mounting cavity, a mounting groove at the top of the mounting body, and a first through hole at the bottom of the mounting groove communicating with the mounting cavity; a liquid guiding component, at least a portion of which is disposed within the mounting groove, having a liquid supply channel extending along its length, a first liquid outlet at one end of the liquid guiding component near the groove opening communicating with the liquid supply channel, and the other end of the liquid guiding component extending through the first through hole into the mounting cavity and having a liquid inlet, the liquid inlet communicating with the liquid supply channel and a liquid supply module of the beauty device; a return channel having a first return port at one end of the return channel near the first liquid outlet, and the other end of the return channel communicating with a negative pressure recovery module of the beauty device; and a care component disposed on the mounting body and / or the liquid guiding component, the care component having a second liquid outlet coaxially disposed with and communicating with the first liquid outlet.

[0005] This application provides a beauty handle, including a mounting body, a liquid guiding component, and a care component. The mounting body has a mounting groove on its top, into which the liquid guiding component is inserted. The liquid guiding component has a liquid supply channel extending along its length. This channel connects to the liquid supply module of the beauty device via an inlet, and its first outlet guides the liquid to a second outlet of the care component for application onto the user's skin. The mounting body has a return channel. One end of the return channel near the first outlet has a first return port, and the other end connects to the negative pressure recovery module of the beauty device. The first return port can quickly draw back residual waste liquid that has not been absorbed by the skin and discharge it to the negative pressure recovery module through the return channel. This solution, by setting up independent liquid supply and return channels, ensures that the liquid supply and recovery operations do not interfere with each other, effectively preventing the mixing of fresh liquid and recycled waste liquid within the channels. Simultaneously, by placing the first return port close to the first outlet, excess waste liquid that is not absorbed after contact with the skin during use can be drawn into the first return port more promptly, improving the timeliness and thoroughness of waste liquid recovery, reducing the possibility of residual liquid spreading along the handle surface, thereby lowering the risk of equipment contamination and improving the user experience.

[0006] In one embodiment, the reflux channel includes a first reflux channel and a second reflux channel. One end of the first reflux channel is provided with a first reflux port, and the other end of the first reflux channel is connected to the second reflux channel. The second reflux channel is used to connect to the negative pressure recovery module of the beauty device. There are at least two first reflux channels, and at least two first reflux ports are arranged circumferentially around the first liquid outlet. By adopting the above structure, residual waste liquid in all directions around the first liquid outlet can be drawn into the reflux channel nearby. Regardless of the direction in which the handle moves back and forth on the skin, it is beneficial to improve the timeliness and uniformity of waste liquid recovery and reduce the possibility of liquid spreading and overflowing along the surface of the handle.

[0007] In one embodiment, each of the first return channels extends along the length of the central axis of the first outlet. The return channel further includes an annular channel, which is coaxially arranged with the first outlet and located below each of the first return channels. The end of each first return channel away from the first return outlet is connected to the annular channel, and the bottom wall of the annular channel is provided with a recovery port connecting to the second return channel. By setting the annular channel, the waste liquid collected in each of the first return channels is concentrated and guided to the recovery port, avoiding the complexity of the pipeline caused by the independent extension of each return channel. The annular channel is coaxially arranged with the first outlet, which helps to optimize the internal space layout of the handle, making the return path more compact and regular, facilitating processing and forming, and reducing manufacturing costs.

[0008] In one embodiment, an annular gap exists between the outer wall of the liquid guide and the inner wall of the mounting groove, separating the first liquid outlet from the first return port. By setting the annular gap to separate the first liquid outlet from the first return port, interference between liquid supply and return is avoided, and fresh liquid is prevented from being directly sucked into the return channel before use, ensuring orderly liquid discharge and recovery operations and improving the usage effect.

[0009] In one embodiment, the peripheral wall of the mounting groove is provided with a first limiting hole, and the outer peripheral wall of the liquid guide is provided with a second limiting hole opposite to the first limiting hole. The first limiting hole and the second limiting hole are connected to each other by a limiting rod. By providing limiting holes corresponding to the peripheral wall of the mounting groove and the outer peripheral wall of the liquid guide respectively, and using the limiting rod for lateral insertion and fixation, mechanical locking between the liquid guide and the mounting body is achieved. This enables bidirectional limiting of the liquid guide in both the circumferential and axial directions, preventing it from rotating or moving within the mounting groove, ensuring that the nursing component is always aligned with the correct liquid outlet direction, and effectively maintaining the annular gap of the return channel.

[0010] In one embodiment, the inner peripheral wall of the mounting groove is provided with a positioning groove extending along the length of the liquid guide, and the outer peripheral wall of the liquid guide is provided with a positioning rib. The positioning rib and the positioning groove form a sliding fit to restrict the circumferential rotation of the liquid guide relative to the mounting groove. By adopting the above structure, the sliding fit between the positioning groove and the rib locks the circumferential rotation of the liquid guide, ensuring that the liquid supply channel and return channel are always precisely aligned with the pre-embedded pipeline in the handle. This avoids pipeline twisting, bending, or interface misalignment caused by rotation, ensuring a smooth liquid transmission path in the narrow cavity, while preventing damage to the flexible tube due to torsional fatigue, thus improving the reliability of the pipeline layout and the durability of the system.

[0011] In one embodiment, the care component includes a first care head and a second care head. The first care head is adapted to be installed at the first liquid outlet. The first care head has a second liquid outlet, and its outer surface has cleaning protrusions or massage protrusions. The second care head is disposed on the mounting body and sleeved on the outer periphery of the first care head. An annular second return port is formed between the second care head and the first care head, and the second return port communicates with the first return port. The second care head is at least one of a microcurrent probe, an ultrasonic probe, a radio frequency heating head, or a massage roller head. By integrating the first care head with protrusions with the functional second care head sleeved on its outer periphery, simultaneous synergy between application cleansing and energy care is achieved. While the second liquid outlet of the first care head outputs the care liquid to the user's skin, its protruding structure simultaneously acts on the user's skin to enhance the physical cleansing effect. The second care head provides deep treatment functions such as microcurrent and radio frequency. At the same time, the annular second return port between the two ensures that excess liquid is promptly recovered on the outer periphery to avoid contamination, achieving an integrated and compact design of liquid supply, care, and recovery.

[0012] In one embodiment, the care assembly includes a first care head and an annular cap. The first care head is adapted to be installed at the first liquid outlet and has a second liquid outlet. The outer surface of the first care head has cleaning or massage protrusions. The annular cap is disposed on the mounting body and fits around the outer periphery of the first care head. An annular second return port is formed between the annular cap and the first care head, and the second return port communicates with the first return port. By utilizing the annular second return port formed between the annular cap and the first care head, excess liquid can be effectively collected and guided into the internal recovery channel, preventing liquid leakage, fulfilling basic liquid supply and recovery functions, and facilitating daily maintenance.

[0013] In one embodiment, the care component includes a first care head adapted to be installed at the first liquid outlet, the first care head having a second liquid outlet, and a vibration mechanism disposed within the mounting cavity. The vibration end of the vibration mechanism is drively connected to the end of the liquid guide member away from the first care head, so as to drive the first care head to vibrate through the liquid guide member. This design places the vibration mechanism within the mounting cavity, with its vibration end drively connected to the end of the liquid guide member away from the first care head. Therefore, the vibration mechanism does not need to directly contact the care head, but instead uses the liquid guide member as a transmission medium, achieving high-frequency vibration drive of the first care head to improve the cleaning or massage effect while maintaining the integrity of the liquid supply channel.

[0014] In one embodiment, the mounting body includes a handle and an elastic seal. The handle has the mounting cavity, and the top of the handle has a limiting portion recessed into the mounting cavity. The limiting portion has a third limiting hole extending along its length. The elastic seal covers one end of the limiting portion near the mounting cavity. The elastic seal and the inner wall of the third limiting hole form the mounting groove. The elastic seal has a first through hole. The elastic seal is sleeved on the outside of the liquid guide through the first through hole and is tightly connected to the outer wall of the liquid guide. By setting an elastic seal to cooperate with the limiting part to form an installation groove, and making the elastic seal fit on the outer peripheral wall of the liquid guide, a sealing interface can be formed between the installation groove and the installation cavity, effectively preventing waste liquid falling into the installation groove from further seeping into the installation cavity and protecting electrical components such as the vibration mechanism from corrosion. On the other hand, the elastic seal can serve as a flexible connection medium between the liquid guide and the limiting part. Its elastic deformation capability allows the liquid guide to swing slightly relative to the limiting part under the drive of the vibration mechanism, which not only ensures the efficient transmission of vibration energy to the first nursing head, but also avoids rigid friction and noise, improving the reliability of the handle and the comfort of use.

[0015] In one embodiment, the limiting portion has a first flange extending radially outward from the third limiting hole at one end near the mounting cavity and a first flange extending radially outward from the end away from the limiting portion and near the mounting cavity at the other end. The elastic sealing element includes a first sealing ring, an elastic structural element, and a second sealing ring arranged radially from the inside out. The first sealing ring is connected to the second sealing ring through the elastic structural element. The first sealing ring has a first through hole and is sleeved on the outer peripheral wall of the liquid guiding element. The second sealing ring abuts and seals with the first flange. The elastic structural element can elastically deform with the vibration of the liquid guiding element, allowing the first sealing ring to move with the liquid guiding element. By adopting the above structure, the elastic structural element acts as a flexible connecting bridge between the first and second sealing rings, so that while the second sealing ring abuts and is fixed with the first flange of the limiting portion, the first sealing ring can be sleeved on the liquid guiding element and move synchronously with it. The elastic structural element absorbs vibration displacement through its own elastic deformation, ensuring that the liquid guiding element is not rigidly locked under vibration drive, and maintaining the sealing interface between the mounting groove and the mounting cavity, thus improving the sealing reliability under vibration conditions.

[0016] In one embodiment, the elastic structural member is annular and extends in a wavy shape along its thickness direction. The first sealing ring and the second sealing ring are respectively connected to both ends of the elastic structural member in the thickness direction, with the first sealing ring located at the end of the elastic structural member away from the limiting portion. By setting the elastic structural member to extend in a wavy shape along the thickness direction, the deformable range of the elastic structural member is increased, allowing it to absorb displacement more fully when the liquid guiding component vibrates. At the same time, the wavy structure has sufficient structural strength while ensuring flexibility, making it less prone to fatigue fracture due to frequent vibration, further improving the sealing reliability and service life under vibration conditions.

[0017] In one embodiment, the elastic structural member is connected to the first sealing ring and / or the second sealing ring via an arc-shaped transition section. The arc-shaped section provides greater elastic deformation margin in both the radial and axial directions, making the deformation of the elastic structural member smoother and more stable, avoiding tearing or detachment of the connection interface due to sudden stress changes, and ensuring structural integrity under long-term vibration conditions.

[0018] In one embodiment, the mounting body further includes a mounting bracket disposed within the mounting cavity. One end of the mounting bracket is fixedly connected to the inner wall of the mounting cavity, and the other end of the mounting bracket forms a second flange, which is disposed opposite to the first flange. The second sealing ring is clamped and fixed between the first flange and the second flange. By adopting the above structure, the mounting bracket is fixedly connected to the inner wall of the mounting cavity, providing a rigid support foundation for the entire elastic seal, ensuring that the second sealing ring always maintains a tight contact with the first flange under long-term vibration conditions, and avoiding seal failure due to loosening.

[0019] In one embodiment, the vibration mechanism is mounted on the mounting bracket.

[0020] In one embodiment, a liquid supply tube is also included, which is disposed in the mounting cavity and extends along the length of the mounting cavity. One end of the liquid supply tube is connected to the liquid inlet, and the other end of the liquid supply tube is used to connect to the liquid supply module of the beauty device.

[0021] In one embodiment, a return pipe is also included, which is disposed in the mounting cavity and extends along the length of the mounting cavity. One end of the return pipe is connected to the return channel, and the other end of the return pipe is used to connect to the negative pressure recovery module of the beauty device.

[0022] In one embodiment, the mounting bracket is provided with a locking position, and the liquid supply pipe and / or the liquid return pipe is locked into the locking position.

[0023] In one embodiment, the vibration mechanism includes a drive motor and a tapping wheel. The drive motor is fixed within the mounting cavity by a mounting bracket. The tapping wheel is eccentrically positioned on the output end of the drive motor. Driven by the drive motor, the outer peripheral wall of the tapping wheel periodically pushes against the end of the liquid guide component away from the first treatment head, thereby driving the liquid guide component to vibrate. This design uses an eccentric tapping wheel in conjunction with a drive motor. The periodic pushing of the outer peripheral wall of the tapping wheel against the end of the liquid guide component generates high-frequency vibrations, which are then transmitted to the first treatment head via the liquid guide component, thus enhancing the cleaning or massage function.

[0024] A second aspect of this application provides a skin management device.

[0025] A skin care device includes: the aforementioned beauty handle; and a beauty instrument comprising a main unit, a liquid supply module, and a negative pressure recovery module. The liquid supply module and the negative pressure recovery module are mounted on the main unit. The liquid supply module is connected to the liquid inlet to deliver care solution to the care components, and the negative pressure recovery module is connected to the return channel to recover used waste liquid. The skin management device provided in the second aspect of this application, by employing any of the aforementioned beauty handles, in conjunction with the liquid supply module and negative pressure recovery module of the beauty instrument, enables the device to continuously supply beauty solution or cleansing solution to the care components at the handle end through the liquid supply module, while simultaneously generating negative pressure in the return channel through the negative pressure recovery module to immediately draw away and recover used waste liquid. The parallel and coordinated operation of the liquid supply and recovery pathways achieves closed-loop fluid management during the care process, ensuring that the skin surface continuously receives clean care solution while preventing waste liquid residue accumulation inside the handle or on the skin surface, effectively improving the hygiene, comfort, and ease of operation of the care process.

[0026] In one embodiment, the liquid supply module includes a pump assembly and a liquid storage tank. The pump assembly is connected to a pipeline between the liquid storage tank and the liquid inlet, and the pump assembly is used to drive the nursing liquid in the liquid storage tank to flow to the first liquid outlet.

[0027] In one embodiment, the negative pressure recovery module includes a waste liquid tank and a negative pressure component, both of which are mounted on the main body. The two ends of the negative pressure module are respectively connected to the reflux channel and the waste liquid tank. The negative pressure module is used to generate negative pressure in the reflux channel to draw waste liquid from the first reflux port into the reflux channel and discharge it into the waste liquid tank.

[0042] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0044] The beauty handle of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0045] like Figures 1 to 7 As shown, this embodiment discloses a beauty handle, including: a mounting body 1, the mounting body 1 having a mounting cavity 101, a mounting groove 102 at the top of the mounting body 1, and a first through hole communicating with the mounting cavity 101 at the bottom of the mounting groove 102; a liquid guiding component 2, at least a portion of which is disposed within the mounting groove 102, the liquid guiding component 2 having a liquid supply channel 201 extending along its length, a first outlet 202 communicating with the liquid supply channel 201 at one end of the liquid guiding component 2 near the opening of the mounting groove 102, and the other end of the liquid guiding component 2 extending through the first through hole into... The mounting cavity 101 is provided with a liquid inlet 203, which is used to connect the liquid supply channel 201 with the liquid supply module of the beauty device. The mounting body is provided with a return channel 204. One end of the return channel 204 near the first liquid outlet 202 is provided with a first return port 205. The other end of the return channel 204 is used to connect to the negative pressure recovery module of the beauty device. The care component 3 is set on the mounting body 1 and / or the liquid guide 2. The care component 3 has a second liquid outlet 301 coaxially arranged with the first liquid outlet 202 and connected to the first liquid outlet 202.

[0046] This application provides a beauty handle, including a mounting body 1, a liquid guide 2, and a care component 3. The mounting body 1 has a mounting groove 102 at its top, into which the liquid guide 2 is inserted. The liquid guide 2 has a liquid supply channel 201 extending along its length. This channel 201 is connected to the beauty device's liquid supply module via an inlet 203, and its first outlet 202 at its end guides the liquid to the second outlet 301 of the care component 3 for application onto the user's skin. The mounting body 1 has a return channel 204. One end of the return channel 204 near the first outlet 202 has a first return port 205, and the other end is connected to the beauty device's negative pressure recovery module. The first return port 205 can quickly draw back residual waste liquid that has not been absorbed by the skin and discharge it to the negative pressure recovery module through the return channel 204. This solution, by setting up independent liquid supply channels 201 and return channels 204, ensures that the liquid supply and recovery operations do not interfere with each other, effectively preventing the mixing of fresh liquid and recovered waste liquid in the channels. At the same time, by setting the first return port 205 close to the first liquid outlet 202, excess waste liquid that is not absorbed after contact with the skin during use can be drawn into the first return port 205 more promptly, improving the timeliness and thoroughness of waste liquid recovery, reducing the possibility of residual liquid spreading along the handle surface, thereby reducing the risk of equipment contamination and improving the user experience.

[0047] like Figure 2 and 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the return channel 204 includes a first return channel 2041 and a second return channel 2042. One end of the first return channel 2041 is provided with a first return port 205, and the other end of the first return channel 2041 is connected to the second return channel 2042. The second return channel 2042 is used to connect to the negative pressure recovery module of the beauty device. The number of first return channels 2041 is at least two, and at least two first return ports 205 are arranged circumferentially around the first liquid outlet 202. By adopting the above structure, residual waste liquid in all directions around the first liquid outlet 202 can be drawn into the return channel nearby. Regardless of the direction in which the handle moves back and forth on the skin, it is beneficial to improve the timeliness and uniformity of waste liquid recovery and reduce the possibility of liquid spreading and overflowing along the surface of the handle.

[0048] like Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: each first return channel 2041 extends along the length of the central axis of the first outlet 202; the return channel 204 also includes an annular channel 2043, which is coaxially arranged with the first outlet 202 and located below each first return channel 2041. The end of each first return channel 2041 away from the first return outlet 205 is connected to the annular channel 2043, and the bottom wall of the annular channel 2043 is provided with a recovery port 2044 connecting to the second return channel 2042. By setting the annular channel 2043, the waste liquid collected by each first return channel 2041 is concentrated and guided to the recovery port 2044, avoiding the complexity of the pipeline caused by the independent extension of each return channel; the annular channel 2043 is coaxially arranged with the first outlet, which is conducive to optimizing the internal space layout of the handle, making the return path more compact and regular, facilitating processing and forming, and reducing manufacturing costs.

[0049] like Figure 2 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: an annular gap 206 is provided between the outer wall of the liquid guide 2 and the inner wall of the mounting groove 102, and the annular gap 206 separates the first liquid outlet 202 from the first return port 205. By setting the annular gap 206 to separate the first liquid outlet 202 from the first return port 205, interference between liquid supply and return is avoided, fresh liquid is prevented from being directly sucked into the return channel before use, ensuring that liquid discharge and recovery operations are carried out in an orderly manner, and improving the usage effect.

[0050] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the peripheral wall of the mounting groove 102 is provided with a first limiting hole 103, and the outer peripheral wall of the liquid guide 2 is provided with a second limiting hole 207 opposite to the first limiting hole 103. The first limiting hole 103 and the second limiting hole 207 are connected to each other by a limiting rod. By providing limiting holes corresponding to the peripheral wall of the mounting groove 102 and the outer peripheral wall of the liquid guide 2 respectively, and using limiting rods for lateral insertion and fixation, mechanical locking between the liquid guide 2 and the mounting body 1 is achieved. This enables bidirectional limiting of the liquid guide 2 in both the circumferential and axial directions, preventing it from rotating or moving within the mounting groove 102, ensuring that the nursing component 3 is always aligned with the correct liquid outlet direction, and effectively maintaining the annular gap 206 of the return channel 204.

[0051] In addition to the features of the above embodiments, this embodiment further specifies that: the inner peripheral wall of the mounting groove 102 is provided with a positioning groove, which extends along the length of the liquid guide 2; the outer peripheral wall of the liquid guide 2 is provided with a positioning rib, which forms a sliding fit with the positioning groove to restrict the circumferential rotation of the liquid guide 2 relative to the mounting groove 102. By adopting the above structure, the sliding fit between the positioning groove and the rib locks the circumferential rotation of the liquid guide 2, ensuring that the liquid supply channel 201 and the return channel 204 are always precisely connected with the pre-embedded pipeline in the handle, avoiding pipeline twisting, bending or misalignment caused by rotation, ensuring smooth liquid transmission path in the narrow cavity, and preventing the flexible tube from breaking due to torsional fatigue, thereby improving the reliability of the pipeline layout and the durability of the system.

[0052] like Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the nursing component 3 includes a first nursing head 31 and a second nursing head 32. The first nursing head 31 is adapted to be installed at the first liquid outlet 202. The first nursing head 31 has a second liquid outlet 301, and the outer surface of the first nursing head 31 is formed with cleaning protrusions or massage protrusions. The second nursing head 32 is disposed on the mounting body 1. The second nursing head 32 is sleeved on the outer periphery of the first nursing head 31, and an annular second return port 302 is formed between the second nursing head 32 and the first nursing head 31. The second return port 302 communicates with the first return port 205. The second nursing head 32 is at least one of a microcurrent probe, an ultrasonic probe, a radio frequency heating head, or a massage ball head. By integrating the first treatment head 31 with protrusions with the functional second treatment head 32 fitted around its periphery, simultaneous and synergistic application of cleansing and energy care are achieved. While the second outlet 301 of the first treatment head 31 delivers the care liquid to the user's skin, its protruding structure simultaneously acts on the user's skin to enhance the physical cleansing effect. The second treatment head 32 provides deep treatment functions such as microcurrent and radiofrequency. At the same time, an annular second return port 302 is formed between the two to ensure that excess liquid is promptly recovered around the periphery to avoid contamination, achieving an integrated and compact design for liquid supply, care, and recovery.

[0053] In addition to the features of the above embodiments, this embodiment further specifies that: the nursing component 3 includes a first nursing head 31 and an annular cover. The first nursing head 31 is adapted to be installed at the first liquid outlet 202. The first nursing head 31 has a second liquid outlet 301, and the outer surface of the first nursing head 31 is formed with cleaning protrusions or massage protrusions. The annular cover is disposed on the mounting body 1 and is sleeved on the outer periphery of the first nursing head 31. An annular second return port 302 is formed between the annular cover and the first nursing head 31, and the second return port 302 communicates with the first return port 205. By utilizing the annular second return port 302 formed between the annular cover and the first nursing head 31, excess liquid can be effectively collected and guided into the internal recovery channel, preventing liquid leakage, satisfying the basic liquid supply and recovery function, and facilitating daily maintenance.

[0054] like Figures 3 to 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the nursing component 3 includes a first nursing head 31, which is adapted to be installed at the first liquid outlet 202. The first nursing head 31 has a second liquid outlet 301. It also includes a vibration mechanism 4, which is disposed in the mounting cavity 101. The vibration end of the vibration mechanism 4 is connected to the end of the liquid guide 2 away from the first nursing head 31, so as to drive the first nursing head 31 to vibrate through the liquid guide 2. This solution sets the vibration mechanism 4 in the mounting cavity 101, and its vibration end is connected to the end of the liquid guide 2 away from the first nursing head 31. Thus, the vibration mechanism 4 does not need to directly contact the nursing head, but uses the liquid guide 2 as a transmission medium, which not only realizes high-frequency vibration drive of the first nursing head 31 to improve the cleaning or massage effect, but also maintains the integrity of the liquid supply channel 201.

[0055] like Figures 3 to 6As shown, in addition to the features of the above embodiments, this embodiment further defines: the mounting body 1 includes a handle 11 and an elastic seal 12. The handle 11 is provided with a mounting cavity 101. The top of the handle 11 is provided with a limiting part 111 recessed into the mounting cavity 101. The limiting part 111 is provided with a third limiting hole 104 extending along its length direction. The elastic seal 12 covers one end of the limiting part 111 near the mounting cavity 101. The elastic seal 12 and the inner wall of the third limiting hole 104 surround to form a mounting groove 102. The elastic seal 12 is provided with a first through hole. The elastic seal 12 is sleeved on the outside of the liquid guide 2 through the first through hole and is tightly connected to the outer wall of the liquid guide 2. By setting the elastic seal 12 to cooperate with the limiting part 111 to form the mounting groove 102, and making the elastic seal 12 sleeve on the outer peripheral wall of the liquid guide 2, a sealing interface can be formed between the mounting groove 102 and the mounting cavity 101, effectively preventing waste liquid falling into the mounting groove 102 from further seeping into the mounting cavity 101, and protecting electrical components such as the vibration mechanism 4 from corrosion; on the other hand, the elastic seal 12 can serve as a flexible connection medium between the liquid guide 2 and the limiting part 111. Its elastic deformation capability allows the liquid guide 2 to swing slightly relative to the limiting part 111 under the drive of the vibration mechanism 4, which not only ensures the efficient transmission of vibration energy to the first nursing head 31, but also avoids rigid friction and noise, improving the reliability of the handle and the comfort of use.

[0056] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting part 111 is provided with a first flange 1111 extending radially outward along the third limiting hole 104 at one end near the mounting cavity 101; the elastic sealing member 12 includes a first sealing ring 121, an elastic structural member 122 and a second sealing ring 123 arranged radially from the inside to the outside; the first sealing ring 121 is connected to the second sealing ring 123 through the elastic structural member 122; the first sealing ring 121 is provided with a first through hole and is sleeved on the outer peripheral wall of the liquid guiding member 2; the second sealing ring 123 abuts and seals with the first flange 1111; the elastic structural member 122 can undergo elastic deformation with the vibration of the liquid guiding member 2 to allow the first sealing ring 121 to move with the liquid guiding member 2. By adopting the above structure, the elastic structural member 122 serves as a flexible connecting bridge between the first sealing ring 121 and the second sealing ring 123. This allows the second sealing ring 123 to abut and be fixed against the first flange 1111 of the limiting part 111, while the first sealing ring 121 can be sleeved on the liquid guide member 2 and move synchronously with it. The elastic structural member 122 absorbs vibration displacement through its own elastic deformation, ensuring that the liquid guide member 2 is not rigidly locked under vibration drive, and maintaining the sealing interface between the mounting groove 102 and the mounting cavity 101, thereby improving the sealing reliability under vibration conditions.

[0057] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the elastic structural member 122 is annular and extends in a wavy shape along its thickness direction; the first sealing ring 121 and the second sealing ring 123 are respectively connected to the two ends of the elastic structural member 122 in the thickness direction; the first sealing ring 121 is located at the end of the elastic structural member 122 away from the limiting part 111. By setting the elastic structural member 122 to extend in a wavy shape along the thickness direction, the deformable range of the elastic structural member 122 is increased, allowing it to absorb displacement more fully when the liquid guiding member 2 vibrates. At the same time, the wavy structure still has sufficient structural strength while ensuring flexibility, and is not prone to fatigue fracture due to frequent vibration, further improving the sealing reliability and service life under vibration conditions.

[0058] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the elastic structural member 122 is connected to the first sealing ring 121 and / or the second sealing ring 123 through an arc-shaped transition section. The arc-shaped section can provide a larger elastic deformation margin in both the radial and axial directions, making the deformation of the elastic structural member 122 more stable and smooth, avoiding tearing or separation of the connection interface due to sudden stress changes, and ensuring the structural integrity under long-term vibration conditions.

[0059] like Figures 3 to 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting body 1 also includes a mounting bracket 13, which is disposed within the mounting cavity 101. One end of the mounting bracket 13 is fixedly connected to the inner wall of the mounting cavity 101, and the other end of the mounting bracket 13 forms a second flange 131, which is disposed opposite to the first flange 1111. The second sealing ring 123 is clamped and fixed between the first flange 1111 and the second flange 131. By adopting the above structure, the mounting bracket 13 is fixedly connected to the inner wall of the mounting cavity 101, providing a rigid support foundation for the elastic seal 12 as a whole, ensuring that the second sealing ring 123 always maintains a tight contact with the first flange 1111 under long-term vibration conditions, and avoiding sealing failure due to loosening.

[0060] like Figures 3 to 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the vibration mechanism 4 is mounted on the mounting bracket 13.

[0061] like Figures 3 to 5 As shown, in addition to the features of the above embodiments, this embodiment further includes a liquid supply pipe 5, which is disposed in the mounting cavity 101.

One end of the liquid supply pipe 5 is connected to the liquid inlet 203, and the other end of the liquid supply pipe 5 is used to connect to the liquid supply module of the beauty device.

[0062] like Figures 3 to 6 As shown, in addition to the features of the above embodiments, this embodiment further includes: a return pipe 6, which is disposed in the mounting cavity 101 and extends along the length of the mounting cavity 101. One end of the return pipe 6 is connected to the return channel 204, and the other end of the return pipe 6 is used to connect to the negative pressure recovery module of the beauty device.

[0063] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting bracket 13 is provided with a locking position 105, and the liquid supply pipe 5 and / or the liquid return pipe 6 are locked in the locking position 105.

[0064] like Figures 4 to 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the vibration mechanism 4 includes a drive motor 41 and a tapping wheel 42. The drive motor 41 is fixed in the mounting cavity 101 by a mounting bracket 13. The tapping wheel 42 is eccentrically disposed on the output end of the drive motor 41. Under the drive of the drive motor, the outer peripheral wall of the tapping wheel 42 periodically pushes the end of the liquid guide 2 away from the first treatment head 31, thereby driving the liquid guide 2 to vibrate. This scheme uses an eccentric tapping wheel 42 in cooperation with the drive motor 41. The outer peripheral wall of the tapping wheel 42 periodically pushes the end of the liquid guide 2 to generate high-frequency vibration, which is then transmitted to the first treatment head 31 through the liquid guide 2, thereby enhancing the cleaning or massage function.

The skin management device provided in the second aspect of this application, by employing any of the aforementioned beauty handles, in conjunction with the liquid supply module and the negative pressure recovery module of the beauty instrument, enables the device to continuously supply beauty solution or cleansing solution to the care component 3 at the handle end via the liquid supply module, while simultaneously generating negative pressure in the return channel 204 via the negative pressure recovery module to immediately draw and recover used waste liquid. The parallel and coordinated operation of the liquid supply and recovery pathways achieves closed-loop fluid management during the care process, ensuring that the skin surface continuously receives clean care solution while preventing waste liquid residue accumulation inside the handle or on the skin surface, effectively improving the hygiene, comfort, and ease of operation of the care process.

[0067] In addition to the features of the above embodiments, this embodiment further specifies that: the liquid supply module includes a pump body assembly and a liquid storage tank, the pump body assembly is connected to the pipeline between the liquid storage tank and the liquid inlet 203, and the pump body assembly is used to drive the nursing liquid in the liquid storage tank to flow to the first liquid outlet 202.
