Description

Technical Field

[0001] This invention relates to the field of medical aesthetics, and more specifically to a beauty device. Background Technology

[0002] In the field of cosmetic medicine, cleansing and wrinkle-removing medical devices are becoming increasingly popular, especially among women. These devices can use pressurized gas to evenly apply beauty products, such as serums, to the areas of the body to be treated, such as the face, hands, and abdomen. This not only smooths out wrinkles on the treated areas but also aims to provide a pleasant experience.

[0003] However, current medical aesthetic devices, based on the ejection of pressurized gas, often generate significant noise, negatively impacting the user experience. The ejection pressure of this gas also needs improvement. Furthermore, the current structure of medical aesthetic devices is uniform, making it difficult to achieve consistently optimal application results when using different beauty products. For example, a device structure suitable for applying serums may not be as effective when applying cleansing solutions. In addition, because pressurized gas flows through the device, the external sealing of the device structure is crucial and requires further improvement. Summary of the Invention

[0004] Therefore, the present invention aims to provide a beauty device that can solve at least one of the aforementioned technical problems existing in the prior art.

[0005] According to one aspect of the present invention, a beauty device is provided, characterized in that the beauty device includes a device body and a device head connected to the distal end of the device body, the device body having a housing and a pressurized gas supply assembly and a beauty product supply assembly disposed in the housing, the pressurized gas supply assembly and the beauty product supply assembly being capable of supplying pressurized gas and beauty product to the device head respectively, the device head having a first cavity, a second cavity and a third cavity adjacent to each other for at least pressurized gas to flow through sequentially, the radial dimensions of the first cavity, the second cavity and the third cavity being designed such that the pressurized gas undergoes radial expansion when entering the second cavity from the first cavity, and then undergoes radial compression when entering the third cavity from the second cavity.

[0006] The advantages of the beauty device of the present invention include, but are not limited to, the following: the design of the three cavities can achieve a very favorable noise reduction effect, which can greatly enhance the user's pleasant experience of the beauty device.

[0007] Advantageously, the average radial dimension of the first cavity is smaller than that of the second cavity, and the average radial dimension of the second cavity is larger than that of the third cavity. The average radial dimension of a cavity can be understood as the average of the radial dimensions of the cavity at different locations along the axial direction; for example, the average radial dimension of a conical cavity is the radial dimension at its axial midpoint.

[0008] Advantageously, the first and second cavities have a cylindrical structure, the third cavity has a conical structure, and the diameter of the first cavity is smaller than the diameter of the second cavity, and the third cavity tapers toward the distal end of the beauty device.

[0009] Advantageously, the distal outlet of the third chamber is open to the external environment, and the device head is provided with a cosmetic product output tube. This cosmetic product output tube extends through the distal outlet of the third chamber and forms a radial gap therebetween, through which pressurized gas and cosmetic products can be ejected into the external environment. Here, because the cosmetic product output tube extends through the distal outlet of the third chamber, pressurized gas can only be ejected through the radial gap, rather than the entire distal outlet. This further enhances the ejection pressure of the pressurized gas, further improving the user's experience. Especially as the beauty process progresses, the pressurized gas in the pressurized gas container decreases, and the pressure drops, yet this design still maintains a relatively high ejection pressure.

[0010] Advantageously, the device head is detachably connected to the device body. The distal outlet of the third chamber and the cosmetic product output tube are configured such that pressurized gas and cosmetic product can be ejected in a direction parallel to the longitudinal axis of the device, or in a direction inclined to the longitudinal axis of the device. The former configuration facilitates the application of the serum to be absorbed by the skin to the area to be treated, while the latter configuration facilitates the cleansing of the area to be treated with a cleansing solution. Because the device head is detachably connected to the device body, device bodies with different configurations can be mounted on the device head according to actual cosmetic needs.

[0011] Advantageously, the beauty device is equipped with at least two types of device heads, each detachably connected to the device body. The distal outlet of the third cavity of the first device head and the beauty product output tube are configured such that pressurized gas and beauty product can be ejected in a direction parallel to the longitudinal axis of the device. Conversely, the distal outlet of the third cavity of the second device head and the beauty product output tube are configured such that pressurized gas and beauty product can be ejected in a direction inclined to the longitudinal axis of the device. Based on the different device heads provided with the beauty device, a single beauty device can be endowed with multiple beauty functions to meet different beauty needs, such as serum application and rinsing functions.

[0012] Advantageously, the device head includes a proximal first portion and a distal second portion, the first and second portions being designed to be independently constructed and connectable to each other.

[0013] Advantageously, the first portion forms the first cavity, and the second portion forms the second cavity and the third cavity.

[0014] Advantageously, the beauty device has a pressurized gas supply assembly within the housing of its main body, the pressurized gas supply assembly having a connection module, a solenoid valve distal to the connection module, and a heating module distal to the solenoid valve.

[0015] Advantageously, the connection module has a connection base having a central channel through which pressurized gas flows.

[0016] Advantageously, the connecting base has a double-step portion at its proximal end, namely a first step portion near the central channel and a second step portion away from the central channel, wherein the diameter of the circumferential surface of the first step portion is larger than the diameter of the central channel, and the diameter of the circumferential surface of the second step portion is larger than the diameter of the circumferential surface of the first step portion.

[0017] Advantageously, the connecting module has a needle mechanism that is housed in the first stepped portion with its base and extends proximally beyond the second stepped portion with its needle.

[0018] Advantageously, the connecting module has a first sealing ring that is received in the second stepped portion, and the outer diameter of the first sealing ring is larger than the diameter of the base of the needle mechanism and the inner diameter of the first sealing ring is smaller than the diameter of the base of the needle mechanism.

[0019] Advantageously, the connecting module has a first fixing plate that can be fixed to the proximal end of the connecting base. The first fixing plate has a through hole with a diameter smaller than the diameter of the circumferential surface of the second step and smaller than the outer diameter of the first sealing ring, such that the first fixing plate at least partially stops the first sealing ring in the axial direction.

[0020] Advantageously, the connecting base has a receiving recess at its distal end, and the connecting module has a second sealing ring that surrounds the proximal port of the solenoid valve and is received therewith in the receiving recess.

[0021] Advantageously, the receiving recess has an annular groove on its inner peripheral wall, the annular groove being shaped to accommodate the second sealing ring.

[0022] Advantageously, the connecting module has a second fixing plate that can be fixed to the distal end of the connecting base. The second fixing plate has a slot that opens radially to one side, the width of which is smaller than the outer diameter of the second sealing ring.

[0023] Advantageously, the connecting module has a solenoid valve clamping mechanism, which includes two screws fixed in the connecting base. The solenoid valve clamping mechanism includes a U-shaped clamping plate that acts on the solenoid valve on one hand and passes through the two screws through through holes on its two U-legs on the other hand. The solenoid valve clamping mechanism also includes at least two positioning nuts that are screwed on the screws and can stop the clamping plate.

[0024] Advantageously, there are two pairs of four positioning nuts, which are screwed onto the screw on both sides of the clamping plate and can stop the clamping plate on both sides.

[0025] Advantageously, the heating module is fitted onto the distal port of the solenoid valve. The heating module has a proximal heating portion and a distal support portion. The heating portion is surrounded by a resistance wire in its circumferential direction, and the support portion extends distally from the bottom wall of the heating portion and is in fluid communication with the heating portion.

[0026] Advantageously, the heating element forms a heating chamber for heating pressurized gas between its bottom wall and the solenoid valve. The heating element has a branch pipe on its peripheral wall, with one end of the branch pipe extending into the heating chamber through the peripheral wall and the other end extending out of the heating chamber.

[0027] Advantageously, the beauty device has a beauty product supply assembly with an interface for a beauty product container, the interface having two hollow needles for inserting into the interior of the beauty product container.

[0028] Advantageously, the head of the device is provided with a cosmetic product output tube, a first flexible tube connects one of the needles to the branch tube, and a second flexible tube connects the other of the needles to the cosmetic product output tube.

[0029] Advantageously, the housing is provided with two opposing operating buttons, and the beauty device can be put into operation by keeping at least one of the operating buttons pressed.

[0059] Next, combine Figures 1a to 10c An exemplary embodiment of the beauty device 1 of the present invention is described. This beauty device 1 can be used to apply beauty products to areas of the body to be treated, such as the face, hands, and abdomen, under certain pressure and low temperature, to smooth wrinkles, moisturize, or cleanse the areas. Therefore, the beauty products can be serums (such as ethanol mixtures), cleansing solutions, etc. The beauty device 1 can be configured to be operated by another person, such as a beautician, or it can be configured to be operated independently by the user.

[0060] In this article, the distal / distal end of the beauty device 1 and its components refers to the end / side facing the area of ​​the body to be treated under normal use, while the proximal / proximal end of the beauty device 1 and its components refers to the end / side away from the area to be treated during use.

[0061] Figures 1a to 1c as well as Figures 8a to 8b The overall appearance of an embodiment of the beauty device 1 is shown.

[0062] The beauty device 1 may include a device body 2 and a device head 3 at its front or distal side. The device body 2 may have a housing 4 for easy gripping, which may be formed by two opposing housing parts or half-shells, for example, screwed together (see...). Figure 3 A user interface 5, including a display screen and buttons, can be provided on the housing 4. The display screen can show operating information to the user. The buttons allow the user to input operating commands. Furthermore, two opposing operating buttons 6 can be provided on the housing 4, specifically on the two half-shells. By holding down at least one of them, the beauty device 1 can be put into operation. The design of the operating buttons 6 is not only ergonomic but also redundant, so that if one malfunctions, the beauty device 1 can still be operated by the other. See also Figure 2a A power cord interface 100 can be provided on the back of the main body 2 of the device, which can be used to connect a power cord to a power source, which can be connected to a standard 220V voltage. The power source can have a voltage regulation function to convert the external voltage into the voltage required by the beauty device 1.

[0063] The device head 3 can be detachably or replaceably connected to the device body 2 or its housing 4. Therefore, the device head 3 in different embodiments ( Figures 1a to 7b The first embodiment of the device head 3 is shown, while Figures 8a to 10c (A second embodiment of the device head 3 is shown) can be selectively mounted on the beauty device 1 to achieve different beauty effects, which will be described in detail below.

[0064] A cosmetic product container 7 and a pressurized gas container 8 can be detachably mounted on the beauty device 1, each containing a cosmetic product and a pressurized gas (e.g., CO2 at 50 bar pressure), respectively. When the beauty device 1 is in operation, the cosmetic product and pressurized gas can be mixed into an atomized gas-liquid mixture and applied to the area of ​​the body to be treated to achieve the desired beauty effect.

[0065] Next, combine Figures 2a to 7c The specific structure and working principle of the beauty device 1 are described herein, which has a device head 3 according to a first embodiment.

[0066] The beauty device 1 may have a pressurized gas supply assembly 9 inside the housing 4 of its main body 2, the perspective view and exploded view of which are respectively shown in Figure 5 and Figure 6 As shown in the diagram, the pressurized gas supply assembly 9 can supply pressurized gas from the pressurized gas container 8 to the device head 3. The pressurized gas supply assembly 9 may have a connection module 10, a solenoid valve 11 distal to the connection module 10, and a heating module 12 distal to the solenoid valve 11.

[0067] The connection module 10 can be used to detachably connect to an external pressurized gas container 8, and can also be connected to a solenoid valve 11, which can be used to block or release the pressurized gas flow. The connection module 10 can connect the pressurized gas container 8 and the solenoid valve 11 to each other.

[0068] Specifically, see Figure 2c and Figure 6 The connection module 10 may have a generally cylindrical connection base 13, which may have a centrally located central channel 14 through which pressurized gas flows.

[0069] The connecting base 13 may have a double-stepped portion coaxial with the central channel 14 at its proximal end, namely a first stepped portion 15 near the central channel 14 and a second stepped portion 16 away from the central channel 14. The first stepped portion 15 and the second stepped portion 16 may each have a radially extending radial surface and an axially extending circumferential surface. The diameter of the circumferential surface of the first stepped portion 15 is larger than the diameter of the central channel 14, and the diameter of the circumferential surface of the second stepped portion 16 is larger than the diameter of the circumferential surface of the first stepped portion 15.

[0070] The connecting module 10 may have a piercing mechanism 17 for puncturing the rubber stopper of the pressurized gas container 8 to release the pressurized gas therein. The piercing mechanism 17 may have a disc-shaped base and a piercing needle centrally connected to the base. The piercing mechanism 17 may be housed in the first stepped portion 15 of the connecting base 13 with its base and abut against the radial and circumferential surfaces, and the piercing mechanism 17 may extend proximally beyond the connecting base 13, or its second stepped portion 16, with its piercing needle.

[0071] The connecting module 10 may have a first sealing ring 18, which may be accommodated in the second stepped portion 16 of the connecting base 13. The outer diameter of the first sealing ring 18 may be larger than the diameter of the base of the needle mechanism 17 and the inner diameter of the first sealing ring 18 may be smaller than the diameter of the base of the needle mechanism 17, such that the first sealing ring 18 can axially compress the base of the needle mechanism 17 to prevent the needle mechanism 17 from moving axially toward the proximal side.

[0072] The connecting module 10 may have a first fixing plate 19, the outer contour of which may correspond to the outer contour of the connecting base 13, and its distal end face may press against the proximal end face of the connecting base 13. The first fixing plate 19 may be fixed to the proximal end of the connecting base 13 by means of screws. The first fixing plate 19 may have a centrally located internally threaded through hole 20. See also Figure 2c The diameter of the through hole 20 can be smaller than the diameter of the circumferential surface of the second step portion 16 connecting the base 13 and smaller than the outer diameter of the first sealing ring 18, so that the first fixing plate 19 can axially compress the first sealing ring 18, and thus the first sealing ring 18 can axially compress the needle mechanism 17 to prevent the first sealing ring 18 and the needle mechanism 17 from moving axially toward the proximal side. The pressurized gas container 8 can be inserted into the through hole 20 with its container opening after passing through the receiving recess 21 on the device body 2 and threaded thereto. This achieves a detachable connection between the pressurized gas container 8 and the device body 2.

[0073] Based on the needle mechanism 17 and the first sealing ring 18, fluid communication between the pressurized gas container 8 and the connecting base 13 can be achieved, ensuring a seal against external contamination.

[0074] See Figure 2c The connecting base 13 may have a receiving recess 22 coaxial with the central channel 14 at its distal end, and the diameter of the receiving recess 22 may be larger than the diameter of the central channel 14. The receiving recess 22 can accommodate the proximal port of the solenoid valve 11.

[0075] The connecting module 10 may have a second sealing ring 23, which may be disposed around the proximal port of the solenoid valve 11 and may be received together in the receiving recess 22. The receiving recess 22 may further have an annular groove 24 on its inner peripheral wall to form-fit the second sealing ring 23. This enhances the sealing effect and prevents the solenoid valve 11 from being excessively pressed against the bottom surface of the receiving recess 22 of the connecting base 13, thus preventing damage to the proximal port of the solenoid valve 11, when it is installed on the connecting base 13.

[0076] The connecting module 10 may have a second fixing plate 25, the outer contour of which may substantially correspond to the outer contour of the connecting base 13 and can press its proximal end face against the distal end face of the connecting base 13. The second fixing plate 25 may be fixed to the distal end of the connecting base 13 by means of screws. The second fixing plate 25 may have an orientation towards one side ( Figure 6The lower side of the second sealing ring 23 has an open groove 26. The width of the groove 26 can be smaller than the outer diameter of the second sealing ring 23, so that the second fixing plate 25 can axially compress the second sealing ring 23 to prevent the second sealing ring 23 from moving axially away from the receiving recess 22. When installing the solenoid valve 11 onto the connecting base 13, the distal port of the solenoid valve 11, together with the second sealing ring 23 fixed thereon, can first be inserted into the receiving recess 22 of the connecting base 13, and then the second fixing plate 25 is installed laterally onto the solenoid valve 11 with its groove 26 and is axially fixed to the connecting base 13 by means of screws.

[0077] The connecting module 10 may include a solenoid valve clamping mechanism 27 for axially clamping the solenoid valve 11 into the connecting base 13. The solenoid valve clamping mechanism 27 may include two screws 28, which pass through a second fixing plate 25 and are fixed in the connecting base 13. The solenoid valve clamping mechanism 27 may include a U-shaped clamping plate 29, which passes through the two screws 28 via through holes at the free ends of its two U-legs, allowing the clamping plate 29 to move axially along the screws 28. The clamping plate 29 engages with the solenoid valve 11 at its lower part (e.g., in a corresponding slot), so that when the clamping plate 29 moves axially along the screws 28, it can drive the solenoid valve 11 to move axially as well. The solenoid valve clamping mechanism 27 may include two pairs of four positioning nuts 30, which are screwed onto the screws 28 on both sides of the clamping plate 29. Therefore, after the solenoid valve 11 is inserted into the connecting base 13, the four positioning nuts 30 are tightened on both sides toward the clamping plate 29 to fix the clamping plate 29 and thus the solenoid valve 11 on both sides, preventing axial movement of the solenoid valve 11. Furthermore, the solenoid valve clamping mechanism 27 can also ensure that the solenoid valve 11 is collinear with the connecting base 13 based on the radial constraint of its clamping plate 29 on the solenoid valve 11. Additionally, the degree of clamping of the solenoid valve 11 in the connecting base 13 can be finely adjusted by finely adjusting the positioning nuts 30.

[0078] The solenoid valve 11 may have a wire inlet 31 for controlling the opening and closing of the solenoid valve 11. When the solenoid valve 11 is open, pressurized gas entering the proximal port of the solenoid valve 11 from the pressurized gas container 8 via the connecting base 13 can flow through the solenoid valve 11 under its own pressure and out from its distal port. When the solenoid valve 11 is closed, pressurized gas is not allowed to flow through the solenoid valve 11 and out from its distal port.

[0079] refer to Figure 2aThe heating module 12 of the pressurized gas supply assembly 9 can be fitted onto the distal port of the solenoid valve 11. The heating module 12 can be used to heat the pressurized gas exiting from the solenoid valve 11. The heating module 12 can be made of ceramic and can have a proximal heating portion 32 and a distal support portion 33. The heating portion 32 can be surrounded by a resistance wire in its circumferential direction. For this purpose, the heating portion 32 can have multiple annular grooves 34 on its outer circumferential surface to accommodate the resistance wire. The heating portion 32 can be sleeve-shaped and can be fitted onto the distal port of the solenoid valve 11. The support portion 33 can extend distally from the bottom wall 35 of the heating portion 32 and is in fluid communication with the heating portion 32 through a through hole in the bottom wall 35. The heating portion 32 forms a heating cavity 36 for heating the pressurized gas between its bottom wall 35 and the distal end face of the solenoid valve 11. The heating portion 32 can have a branch pipe 37 on its peripheral wall, with one end extending into the heating cavity 36 through the peripheral wall and the other end extending out of the heating cavity 36. Thus, a portion, or most, of the heated pressurized gas can enter the support portion 33 through the through-hole on the bottom wall 35, while another portion, or a small portion, can exit the heating chamber 36 through the branch pipe 37. See also Figure 4 The support portion 33 can be inserted and supported in the first through hole 38 formed at the far end of the housing 4.

[0080] See Figure 3 and Figure 6 The beauty device 1 may have a control module 39, such as a circuit board, which controls the operation of the beauty device 1 according to the operator's input information. For example, when receiving the corresponding input information from the operator, the control module 39 can control the heating module 12 of the pressurized gas supply component 9 and the opening and closing of the solenoid valve 11.

[0081] See Figure 2a and Figure 3 The beauty device 1 may have a beauty product supply assembly 40, which may have an interface 41 for a beauty product container 7, which may be fixed to the housing 4. The interface 41 may have a receiving portion 101 for receiving the container opening of the beauty product container 7. This receiving portion 101 may have two hollow needles (not shown) on the side facing the beauty product container 7 to pierce its rubber stopper and extend into the container's interior when the beauty product container 7 is installed. The two needles are respectively connected to two hoses 42 and 43 outside the interface 41, wherein the first hose 42 is connected to a branch pipe 37 of the heating module 12 of the pressurized gas supply assembly 9, so that a portion of the heated pressurized gas can enter the interior of the beauty product container 7 through the first hose 42, and this portion of pressurized gas can then carry the beauty product inside the beauty product container 7 out through the second hose 43. See also Figure 4The second flexible tube 43 can be inserted and fixed in the second through hole 44 formed at the distal end of the housing 4. The second through hole 44 can be arranged parallel to the first through hole 38, see [reference]. Figure 2b and Figure 4 .

[0082] The following describes different embodiments of the device head 3 with reference to the accompanying drawings.

[0083] The first embodiment of the device head 3 is composed of Figure 2b and Figures 7a to 7c Clearly visible. The device head 3 may include a proximal first portion 45 and a distal second portion 46. The first portion 45 and the second portion 46 may be designed to be manufactured independently of each other and can be connected to each other, such as by snap-fit ​​or screw connection. The two-part device head 3 facilitates its manufacture. See also Figure 2b The first part 45 can be fitted onto the distal end of the device body 2 at its proximal end and can be sealed by means of a sealing ring. The first part 45 may have a front wall 47 extending perpendicular to the longitudinal axis of the beauty device 1 (here, the longitudinal axis of the pressurized gas supply assembly, or the direction along which the pressurized gas flows through the pressurized gas supply assembly). A cylindrical first cavity 48 may be provided in the front wall 47. The diameter of the first cavity 48 is substantially equal to the diameter of the first through hole 38 at the distal end of the housing 4, and is aligned with the first through hole 38 in the installed state, so that the pressurized gas flowing out from the support portion 33 of the heating module 12 can enter the first cavity 48. The second part 46 of the device head 3 may form a generally cylindrical second cavity 49 at its proximal end and a generally conical third cavity 50 at its distal end. The second cavity 49 and the third cavity 50 are arranged substantially coaxially with the first cavity 48.

[0084] Here, the diameter of the second cavity 49 is larger than that of the first cavity 48, for example, 1.5 to 3 times larger. The conical third cavity 50 tapers distally, with its proximal end adjacent to the second cavity 49 and its distal end open to the external environment, ending with a circular outlet 51. The diameter (far) of the circular outlet 51 is smaller than that of the first cavity 48. This design of the three cavities 49, 50, and 51 achieves a very favorable noise reduction effect. The pressurized gas is relatively noisy when it enters the first cavity 48 after leaving the heating module 12. The pressurized gas then enters the second cavity 49 and can rapidly expand radially within it. The pressurized gas then enters the third cavity 50 and is compressed due to its conical structure. This process of expansion followed by compression of the pressurized gas results in a significant reduction in noise. In practice, the noise of the beauty device 1 can cause discomfort to the user, and this noise is mainly generated by the pressurized gas flowing out of the circular outlet 51. However, the noise is significantly reduced after being processed by the device head 3 in this way. Tests have shown that noise can be reduced by about 10dB, which greatly enhances the user experience.

[0085] The device head 3 may also be equipped with a cosmetic product output tube 52, which may be configured as a metal bend 52. See also Figure 7b The metal bend 52 may include a proximal section 102 and a distal section 104 extending parallel to the longitudinal axis of the device, and a connecting section 103 connecting the two and inclined to the longitudinal axis of the device. See also Figure 2b The bend 52, with its proximal section 102 passing through the front wall 47, is fixed in the front wall 47 by means of a fixing block 53 fitted thereon, and communicates with the second through hole 44 at the distal end of the housing 4. Its distal section 104 passes centrally through the circular outlet 51 of the second portion 46, communicating with the external environment. The distal end face of the bend 52 extends beyond or is flush with the end face of the circular outlet 51 (in this embodiment). Thus, pressurized gas flowing from the second hose 43, along with the cosmetic product, can be delivered through the bend 52 to the external environment adjacent to the circular outlet 51. See also... Figure 2b An annular gap 54 can be formed between the peripheral wall of the curved tube 52 and the circular outlet 51, through which pressurized gas can flow from the third chamber 50 into the environment. The pressurized gas flowing out of the annular gap 54 can surround the cosmetic product flowing out of the curved tube 52 and further break it into a mist in the external environment, which is beneficial for the even application to the area to be treated.

[0086] Due to the smaller size of the annular gap 54, the pressure of the pressurized gas after passing through it can be significantly increased. Tests have shown that the pressure can increase by approximately 30%, which further enhances the user's comfort experience.

[0087] Therefore, the device head 3 design of the present invention can reduce noise on the one hand, and increase the pressure of pressurized gas flowing out of the beauty device 1 on the other. This can greatly enhance the user experience of the beauty device 1 and bring a huge competitive advantage to the product itself.

[0088] In the first embodiment, the circular outlet 51 and the curved tube outlet 52 of the device head 3 are configured or oriented such that the pressurized gas flowing from the circular outlet 51 and the cosmetic product (specifically, the pressurized gas-cosmetic product mixture) flowing from the curved tube outlet 52 can both flow towards the front of the beauty device 1, i.e., in a direction parallel to the longitudinal axis of the device. Therefore, in the normal vertical positioning of the beauty device 1 relative to the area to be treated, the mixture formed by the pressurized gas and the cosmetic product can be applied to the area to be treated substantially perpendicularly. Here, the cosmetic product can be a serum. The serum sprayed from the device head 3 with this vertical orientation can be better applied to the area to be treated and absorbed by the skin.

[0089] The second embodiment of the device head 3 can be made by Figures 8a to 10cAs can be seen, similarly, the device head 3 may include a proximal first portion 45 and a distal second portion 46. The difference between the device head 3 in the second embodiment and the device head 3 in the first embodiment lies in the inclined orientation design of the circular hole outlet 51 and the bent tube outlet 52 on the second portion 46. That is, unlike the orientation of the circular hole outlet 51 and the bent tube outlet 52 parallel to the longitudinal axis of the device in the first embodiment, in the second embodiment, see... Figure 10b The circular outlet 51 and the outlet of the bent tube 52 (and therefore the annular gap 54) are inclined to the longitudinal axis of the device, for example, forming an acute angle with it, such as 45 degrees. That is, in the second embodiment, the circular outlet 51 and the outlet of the bent tube 52 of the device head 3 are constructed or oriented such that the pressurized gas flowing out of the circular outlet 51 or the annular gap 54 and the pressurized gas-cosmetic mixture flowing out of the outlet of the bent tube 52 can be ejected at an angle. Here, the metal bent tube 52 may have an inclined portion 105 at the distal end of the distal section 104.

[0090] Therefore, in the normal vertical positioning of the beauty device 1 relative to the area to be treated, the mixture formed by pressurized gas and beauty product can be applied to the area at an angle. Here, the beauty product can be a cleansing solution, which can be used to clean dirt from the skin. The cleansing solution sprayed from the device head 3 with this angled orientation can better flush out dirt from the skin.

[0091] Since the device head 3 is detachably connected to the device body 2, different device heads 3 in the first and second embodiments can be selectively installed on the device body 2 to achieve different cosmetic purposes. For example, if the skin needs to be cleansed first during the cosmetic process, the device head 3 of the second embodiment can be installed along with the cleansing liquid container 7 to achieve the cleansing purpose. However, if, after cleansing, a serum needs to be applied to the area to be treated to remove wrinkles, the device head 3 and serum container 7 of the first embodiment can be used instead.

[0092] This invention may include any feature or combination of features or generalization thereof implied or expressly disclosed herein, and is not limited to any of the defined scopes listed above. Any elements, features and / or structural arrangements described herein may be combined in any suitable manner.

[0093] The specific embodiments disclosed above are merely exemplary, and it will be apparent to those skilled in the art, upon which the teachings herein will be adapted and implemented in different but equivalent ways. Therefore, it is evident that changes and modifications can be made to the specific embodiments disclosed above, and all such variations are considered to fall within the scope and spirit of the invention.
