Description

Technical Field

[0001] This invention relates to a suction head and a skin care device equipped with the suction head, and more particularly to a suction head that can prevent the airflow path from being blocked by therapeutic cream during vacuum suction and a skin care device equipped with the suction head. Background Technology

[0002] Generally speaking, skin beauty devices that utilize negative pressure work by placing the suction head on a specific area of ​​the patient's skin and then using a pump to apply negative pressure to the skin to achieve a therapeutic effect. Currently, with the diversification of skin treatments, its use is showing a gradual increasing trend.

[0003] Medical devices that utilize negative pressure include, for example, massage devices that utilize vacuum, fat-decomposing devices that use vacuum to adsorb onto the patient's skin and decompose fat by irradiating the inhalation site with ultrasound, and cupping devices that achieve traditional Chinese medicine therapeutic effects by adsorbing onto the skin.

[0004] In addition, the suction head may include RF electrodes to achieve a massage effect using negative pressure and a skin beautification effect using RF electrodes.

[0005] RF electrodes (radio frequency) can heat the skin and subcutaneous tissue for therapeutic purposes. They can be used to restore the skin by raising its temperature after cooling fat breakdown treatment in obesity treatment, and in skin treatments that promote collagen contraction or induce wound healing by heating the skin and subcutaneous tissue.

[0006] Specifically, RF electrodes can promote collagen contraction or wound healing responses in the lower dermis by applying electrical signals, and are thus widely used for purposes such as skin resurfacing, wrinkle removal, treatment of sebaceous glands and hair follicle fat tissue, and spider veins.

[0007] The suction head is connected to a vacuum device via a suction tube to create negative pressure inside it, and negative and positive pressure are alternately and repeatedly created in the negative pressure space in contact with the skin via the suction tube.

[0008] Furthermore, the suction head may apply a therapeutic cream to the skin during treatment to enhance the therapeutic effect. In this case, there is a problem that the therapeutic cream applied to the skin is suctioned by negative pressure during treatment and drawn into the airflow path of the suction tube through the suction port along the inner side of the negative pressure space.

[0009] In particular, for suction heads equipped with RF electrodes, in order to reduce pain when applying electrical stimulation to the skin via the RF electrodes and minimize side effects, a therapeutic cream must be applied. As a result, the therapeutic cream is frequently drawn into the airflow path of the suction tube through the suction port along the inner side of the negative pressure space during treatment.

[0010] When the therapeutic cream is drawn into the airflow path of the inhalation tube, the therapeutic effect may decrease due to the inability to apply negative pressure evenly. Furthermore, the therapeutic cream remaining in the airflow path may solidify, causing blockage of the inhalation tube.

[0011] Furthermore, the therapeutic cream inhaled into the airflow path can reduce the durability of the vacuum device, and in the event of blockage of the inhalation tube, it can cause treatment interruption, resulting in problems that require time and expense to resolve.

[0012] For existing suction heads equipped with RF electrodes, a replaceable filter is installed at the suction inlet to prevent the therapeutic cream from being drawn into the airflow path during treatment. However, this has the inconvenience of needing to replace the filter periodically, and the filter may cause a drop in negative and positive pressure. When foreign objects are stuck in the filter, the negative and positive pressures may drop further, making it difficult to maintain the set pressure stably.

[0013] Prior patents related to the invention in this case include Korean Patent Publication No. 2021-0147811, “Therapeutic Device Using a Vacuum Cup” (published on December 7, 2021). Summary of the Invention

[0014] Technical issues

[0015] The purpose of this invention is to provide a suction head that can prevent therapeutic cream from being drawn into the airflow path by negative pressure during treatment without a filter, and a skin beauty device equipped with the suction head.

[0016] Another object of the present invention is to provide a suction head that can effectively generate negative and positive pressure within a negative pressure forming space, and a skin beauty device equipped with said suction head.

[0017] Technical solution

[0018] To achieve the objectives of the present invention as described above, an embodiment of the suction head according to the present invention is characterized by comprising: a head body portion equipped with a negative pressure forming space open to a surface in contact with the skin; an air negative pressure tube component located within the head body portion, connecting the suction port of the negative pressure forming space to a vacuum device of the control body portion; and a cream movement guiding component installed within the negative pressure forming space at the suction port, guiding the flow of therapeutic cream moving along the inner side of the negative pressure forming space toward the suction port side to the lower side, thereby preventing it from flowing into the suction port.

[0019] In this invention, the cream movement guide can be detachably attached to the suction port.

[0020] In this invention, a connecting tube is formed in the upper part of the negative pressure forming space, which protrudes from the suction port to allow the cream movement guide to be connected in a separable manner.

[0021] In this invention, the cream movement guide may include: a connecting protrusion that connects to the suction port; and a cream receiving portion formed around the outer side of the connecting protrusion, such that a therapeutic cream moving downward along the outer side of the connecting protrusion rests on the upper portion.

[0022] In this invention, a connecting tube is formed protruding from the suction port at the upper part of the negative pressure forming space, which allows the cream movement guide to be connected in a separable manner. The cream movement guide causes the connecting tube to be embedded inside the connecting protrusion and connected.

[0023] In this invention, the end of the connecting protrusion can be positioned at a point that abuts against the upper surface of the negative pressure forming space.

[0024] In this invention, the upper surface of the cream receiving portion can be inclined downward from the end side to form a first inclined surface that allows the therapeutic cream to move downward.

[0025] In this invention, the lower surface of the cream receiving portion can be formed by a second inclined surface that causes air to converge toward the inlet side.

[0026] In this invention, the upper surface of the cream receiving portion may be formed by a first inclined surface that is inclined downward from the end side to allow the therapeutic cream to move downward, and the lower surface may be formed by a second inclined surface that allows air to converge toward the inhalation port side.

[0027] In this invention, a cream storage section may be provided on the upper surface of the cream receiving portion for storing surgical cream that moves downward along the connecting protrusion.

[0028] In this invention, the upper end of the connecting protrusion may be equipped with an inclined surface for guiding the therapeutic cream, which moves upward along the inner side of the negative pressure forming space, to the outer side of the connecting protrusion.

[0029] In this invention, the cream movement guide component is attached to the upper side of the negative pressure forming space in a way that allows it to move up and down and is elastically supported by a spring component, thereby moving up and down when alternating between negative and positive pressure within the negative pressure forming space.

[0030] In this invention, the cream moving guide component allows the connecting protrusion to penetrate the upper surface of the negative pressure forming space and be connected in a way that allows it to move up and down. A spring support portion is provided on the inner side of the connecting protrusion to provide elastic support for the spring component. The spring component can be disposed between the spring support portion and the upper surface of the negative pressure forming space, thereby providing elastic support for the cream moving guide component.

[0031] In this invention, the spring support portion can be provided on the lower end side of the inner side of the connecting protrusion and is equipped with a spring insertion groove for inserting the spring component, so that when the cream moving guide component is raised and lowered, the upper end side is supported by the upper surface of the negative pressure forming space and thereby restricts the range of raising and lowering movement.

[0032] In this invention, the upper surface of the negative pressure forming space allows the connecting protrusion to pass through and connect, and a lifting guide tube is provided to guide the up and down movement of the connecting protrusion. On the upper end side of the connecting protrusion, a limiting protrusion is provided that is snapped onto the upper end side of the lifting guide tube.

[0033] In this invention, an O-ring for preventing the flow of therapeutic cream located on the outer side of the connecting protrusion may be provided on the inner side of the lifting guide tube.

[0034] In order to achieve the objectives of the present invention as described above, an embodiment of a skin beauty device according to the present invention is characterized by comprising: a suction head; and a control body connected to the suction head and equipped with a vacuum device connected to the negative pressure forming space of the suction head; the suction head is an embodiment of a suction head according to the present invention.

It can also improve the durability of the vacuum device and save the cost and time required to repair the airflow path blocked by therapeutic cream.

[0037] This invention can prevent therapeutic cream from being drawn into the airflow path by negative pressure during treatment without a filter, thereby stabilizing the negative and positive pressures at the set pressures during treatment and improving the treatment effect. Moreover, it eliminates the need to replace or manage filters, thus significantly saving the cost and time required for equipment management. Attached Figure Description

[0049] Figure 1 This is a schematic diagram illustrating a skin beauty device equipped with a suction head 10 according to the present invention. Figure 2 This is a cross-sectional view illustrating an embodiment of the suction head 10 according to the present invention.

[0050] Next, please refer to Figure 1 as well as Figure 2 A detailed description will be given of one embodiment of the suction head 10 and the skin beauty device equipped with the suction head according to the present invention.

[0051] The skin beauty device equipped with a suction head 10 according to the present invention includes a suction head 10 according to the present invention and a control body 20 connected to the suction head 10 and equipped with a vacuum device connected to the negative pressure forming space 100a of the suction head 10.

[0052] The suction head 10 according to the present invention is equipped with a negative pressure forming space 100a that is placed on the skin and opens to the surface in contact with the skin, and may include an RF electrode part 400 that is in contact with the skin and applies RF electrical signals to the skin.

[0053] The control unit 20 is connected to the suction head 10 via a head cable body 30, which includes control cables and suction and exhaust pipes, and includes a vacuum device that can repeatedly generate negative and positive pressure within the negative pressure forming space 100a of the suction head 10.

[0054] The control cable is used to control the operation of the RF electrode section 400. The intake and exhaust pipe includes a pipe component that is connected to the vacuum device of the control main body section 20 and draws in or supplies air to the negative pressure forming space 100a.

[0055] It should be noted that since the control unit 20 and the head cable 30 can be implemented in various modifications according to known examples in known negative pressure therapy devices that control the operation of the suction head 10 equipped with RF electrodes, detailed descriptions will be omitted.

[0056] Furthermore, one embodiment of the suction head 10 according to the present invention includes a head body 100 equipped with a negative pressure forming space 100a open to the surface in contact with the skin.

[0057] The main body 100 of the machine head is equipped with a negative pressure forming space 100a that is open to the contact surface that contacts the lower part.

[0058] As an example, the head body 100 includes a cup portion 110 inside which a negative pressure forming space 100a is formed. The cup portion 110 has a shape including a dome 111 in the shape of a hemispherical dome and a cylindrical portion 112 in the shape of a cylinder located on the lower side of the dome 111. The lower end of the cylindrical portion 112 is connected to the lower surface of the head body 100, i.e., the contact surface, and has a structure that is in contact with the skin.

[0059] In addition, the negative pressure forming space 100a can also be implemented in various modifications according to the known shape of the suction head 10, so detailed descriptions will be omitted.

[0060] In addition, an intake port 100b is provided in the negative pressure forming space 100a for forming negative pressure by drawing in internal air or forming positive pressure by supplying internal air.

[0061] As an example, the intake port 100b is located at the center of the negative pressure forming space 100a, that is, at the center of the dome 111. By being located at the center of the dome 111, air in the negative pressure forming space 100a can be drawn in evenly and supplied evenly to the negative pressure forming space 100a.

[0062] The inlet 100b is connected to the vacuum device of the control body 20 via an air intake pipe component 200 provided in the main body 100 of the machine head.

[0063] The air intake pipe component 200 can be integrated with the intake and exhaust pipe of the head cable body 30 to form a single pipe, or it can be detached from the intake and exhaust pipe of the head cable body 30.

[0064] Furthermore, as an example, multiple RF electrode portions 400 are provided on the contact surface of the head body portion 100, and as an example, an annular electrode shape is adopted around the entrance of the negative pressure forming space 100a.

[0065] Furthermore, the RF electrode section 400 is located at a position spaced apart from the contact surface of the head body section 100, and may include a plurality of annular RF electrodes.

[0066] As an example, multiple RF electrode sections 400 are annular electrodes with different diameters, and can have the same width or different widths, so that they are positioned at intervals between each other on the contact surfaces of the head body section 100.

[0067] Although not shown in the figure, the RF electrode part 400 may also be located on the inner side of the negative pressure forming space 100a, so as to contact the skin part that protrudes into the negative pressure forming space by means of negative pressure.

[0068] In summary, the RF electrode 400 is disposed in the head body 100 at a position in contact with the skin, thereby applying an RF electrical signal to the skin in contact.

[0069] The RF electrode 400 is a well-known RF electrode that promotes collagen contraction or wound healing response in the lower dermis by applying an electrical signal. Therefore, detailed descriptions will be omitted.

[0070] The head body 100 is equipped with a control wire section (not shown) that controls the operation of the RF electrode section 400 by connecting the RF electrode section 400 to the control body 20.

[0071] The control cable section can be integrated with the control cable of the machine head cable body 30 to form a conduit, or it can be a structure that can be separated from the control cable of the machine head cable body 30.

[0072] A cream movement guide 300 is installed in the suction port 100b of the negative pressure forming space 100a to prevent the therapeutic cream from flowing into the suction port 100b by guiding it downward along the inner side of the negative pressure forming space 100a toward the suction port 100b.

[0073] The cream movement guide component 300 allows the therapeutic cream applied to the skin during treatment to move along the inner side of the negative pressure forming space 100a toward the suction port 100b formed on the upper surface, and then downward to the skin.

[0074] The cream movement guide 300 is provided at the suction port 100b located on the upper side of the negative pressure forming space 100a, so that the therapeutic cream moving upward along the negative pressure forming space 100a flows downward along the outer side, thereby preventing it from being sucked into the suction port 100b.

[0075] The therapeutic cream can be a negative pressure therapy cream used during negative pressure therapy, or an RF therapy cream used during RF therapy.

[0076] Generally speaking, in order to reduce pain and minimize side effects during RF treatment, RF treatment cream must be applied. As a result, during the treatment, the RF treatment cream may flow into the inhalation port 100b as it moves along the inner side of the negative pressure forming space 100a toward the inhalation port 100b.

[0077] As an example, in the suction head 10 that performs RF therapy and negative pressure therapy in parallel, the cream movement guide component 300 can prevent RF therapy cream that moves along the inner side of the negative pressure forming space 100a towards the suction port 100b during treatment from flowing into the suction port 100b.

[0078] The cream movement guide component 300 includes a connecting protrusion 310 that is connected to the suction port 100b and a cream receiving portion 320 formed around the outer side of the connecting protrusion 310 and allowing the therapeutic cream to be placed on the upper surface for downward movement along the outer side of the connecting protrusion 310.

[0079] As an example, the protrusion 310 adopts a tubular shape with a central hole extending along the length direction, and has a structure that can be easily separated by being embedded inside or outside the suction port 100b.

[0080] More specifically, as an example, at the upper part of the negative pressure forming space 100a, a connecting tube 120 is formed protruding from the suction port 100b, which can be detachably connected to the cream movement guide member 300, and the cream movement guide member 300 can be embedded and connected to the interior of the connecting protrusion 310 by the connecting tube 120.

[0081] Furthermore, the end of the connecting protrusion 310 is positioned to abut against the upper surface of the negative pressure forming space 100a, i.e., the upper surface of the cup portion 110, thereby preventing the therapeutic cream from flowing in and remaining between the end of the connecting protrusion 310 and the negative pressure forming space 100a.

[0082] The connecting tube 120 is designed to be inserted into and connected to the hollow portion of the connecting protrusion 310 without reducing the diameter of the suction port 100b. Furthermore, the end of the connecting protrusion 310 is positioned to abut against the upper surface of the negative pressure forming space 100a. This prevents the therapeutic cream from remaining between the end of the connecting protrusion 310 and the negative pressure forming space 100a as it moves downward along the outer periphery of the connecting protrusion 310 when it moves to the upper surface of the negative pressure forming space 100a. Instead, it moves downward smoothly.

[0083] That is, the cream movement guide component 300 includes a connecting protrusion 310 that is attached to the suction port 100b and protrudes downward toward the suction port 100b, thereby causing the therapeutic cream that has moved to the upper surface of the negative pressure forming space 100a to move downward along the outer surface.

[0084] Furthermore, a cream receiving portion 320 is provided around the outer side of the connecting protrusion 310, on which a therapeutic cream can be placed on the upper side for downward movement.

[0085] The cream receiving portion 320 can expand the end cross-sectional area of ​​the connecting protrusion 310 that allows the therapeutic cream to move in the downward direction, thereby preventing the therapeutic cream from flowing into the hollow portion of the connecting protrusion 310 when air is drawn in from the end of the connecting protrusion 310 through the suction port 100b.

[0086] The cream receiving portion 320 forms an area that can prevent the therapeutic cream located on the outer periphery from flowing back into the inlet 100b side under the suction pressure of the inlet 100b.

[0087] As an example, the cream receiving portion 320 has a diameter that is at least twice the diameter of the connecting protrusion 310 or the diameter of the suction port 100b, thereby preventing the therapeutic cream from flowing back into the suction port 100b side.

[0088] As an example, the cream receiving portion 320 is formed in the shape of a disc surrounding the outer side of the connecting protrusion 310.

[0089] Furthermore, the upper surface of the cream receiving portion 320 is formed by an inclined surface that slopes downward from the end side, thereby guiding the therapeutic cream placed on the upper side to move towards the end side.

[0090] Furthermore, the lower surface of the cream receiving portion 320 is formed by an inclined surface with a shape that gradually extends outward from the suction port 100b side to the end side.

[0091] That is, as an example, the cream receiving part 320 is formed by a first inclined surface 320a, the upper surface of which is inclined downward from the end side so that the therapeutic cream can move downward, and the lower surface is formed by a funnel shape by a second inclined surface 320b that causes air to gather towards the inlet 100b side.

[0092] The cream receiving part 320 can guide the air in the negative pressure forming space 100a to the suction port 100b side of the second inclined surface 320b on the lower side when a negative pressure is formed, thereby ensuring that it is smoothly sucked in. When a negative pressure is formed, the air supplied to the negative pressure forming space 100a is diffused in a wider direction, thereby maximizing the preset negative pressure and positive pressure when negative pressure and positive pressure are repeatedly generated, thereby shortening the cycle of positive pressure and negative pressure.

[0093] Furthermore, the cream receiving portion 320 can guide the therapeutic cream that has moved along the connecting protrusion 310 to the upper surface to move downward along the inclined first inclined surface 320a and fall to the end side.

[0094] The cream receiving part 320 can allow the therapeutic cream to move smoothly downward and fall back onto the skin to return to its original position through the first inclined surface 320a on the upper side, thereby minimizing the amount of therapeutic cream replenished during the treatment process and minimizing the amount of therapeutic cream remaining in the negative pressure forming space 100a after treatment.

[0095] In summary, the therapeutic cream applied to the skin can move along the inner side of the negative pressure forming space towards the suction port 100b located on the upper surface of the negative pressure forming space 100a during the treatment process when negative and positive pressure are alternately generated in the negative pressure forming space 100a.

[0096] Furthermore, the therapeutic cream can be guided downward along the outer side of the connecting protrusion 310 protruding from the suction port 100b after being moved to the suction port 100b side, thereby moving to the cream receiving portion 320, and then moving downward along the first inclined surface 320a on the upper surface of the cream receiving portion 320 and falling onto the skin again.

[0097] Figure 3 as well as Figure 4 This is a cross-sectional view illustrating another embodiment of the suction head 10 according to the present invention, see reference. Figure 3 as well as Figure 4 A cream storage section 321 is provided on the upper side of the cream receiving section 320 to store the therapeutic cream that descends along the connecting protrusion 310. This stores and preserves the therapeutic cream that rises along the inner side of the negative pressure forming space 100a after use in the cream storage section 321, thereby preventing it from flowing into the suction port 100b.

[0098] For treatments that remove metabolic waste from the skin, since the therapeutic cream contains metabolic waste from the skin, it is possible to prevent the therapeutic cream containing metabolic waste from falling back onto the skin and being reused. Instead, it can be stored and kept in the cream storage section 321 formed on the upper side of the cream receiving section 320. After treatment, the cream moving guide 300 can be separated from the suction port 100b and reused after washing.

[0099] Cream movement guide component 300 Figure 3 As shown, a funnel shape with a diameter that gradually increases towards the upper side can be adopted to form a cream storage section 321 within the funnel.

[0100] In addition, the cream movement guide component 300, such as Figure 4 As shown, a cream storage portion 321 with a shape that is recessed along the outer periphery of the connecting protrusion 310 can be adopted on the upper side.

[0101] On the upper side of the cream movement guide member 300, a cream storage section 321 can be formed in various forms to store the therapeutic cream that descends along the outer side of the connecting protrusion 310.

[0102] Furthermore, the cream movement guide component 300 can be manufactured into various appropriate shapes according to the treatment requirements and can be detachably attached to the inhalation port 100b, thereby allowing the appropriate shape to be attached to the inhalation port 100b for use according to the treatment.

[0103] The therapeutic cream applied to the skin can move along the inner side of the negative pressure forming space 100a towards the suction port 100b located on the upper surface of the negative pressure forming space 100a during the treatment process when negative pressure and positive pressure are alternately generated in the negative pressure forming space 100a.

[0104] Furthermore, the therapeutic cream can be guided downward along the outer side of the connecting protrusion 310 protruding from the suction port 100b after being moved to the suction port 100b side, thereby moving to the cream receiving portion 320, and then moving downward along the first inclined surface 320a on the upper surface of the cream receiving portion 320 and falling onto the skin again.

[0105] Furthermore, the upper end of the connecting protrusion 310 is provided with an inclined surface 323 for guiding the therapeutic cream that rises along the negative pressure forming space 100a to the outer side of the connecting protrusion 310.

[0106] The inclined surface 323 for guiding cream movement is formed in a tapered shape with a diameter that gradually increases from the upper end of the connecting protrusion 310, thereby surrounding the outer side of the suction port 100b and adhering to the upper surface of the negative pressure forming space 100a.

[0107] The inclined surface 323 for guiding the movement of the cream can guide the therapeutic cream, which rises along the inner side of the negative pressure forming space 100a toward the suction port 100b, to the outer side of the connecting protrusion 310, thereby preventing the therapeutic cream from being stuck in a specific part during movement.

[0108] also, Figure 5 This is a cross-sectional view illustrating another embodiment of the suction head 10 according to the present invention, see reference. Figure 5 The cream movement guide component 300 is attached to the upper side of the negative pressure forming space 100a in a way that allows it to move up and down and is elastically supported by the spring component 500, thereby moving up and down when negative pressure and positive pressure are alternately and repeatedly formed in the negative pressure forming space 100a.

[0109] More specifically, the cream movement guide component 300 can be coupled to the upper surface of the negative pressure forming space 100a through the connecting protrusion 310 and can be moved up and down. A spring support part 311 is provided on the inner side of the connecting protrusion 310 to provide elastic support for the spring component 500. The spring component 500 can be disposed between the spring support part 311 and the upper surface of the negative pressure forming space 100a, thereby providing elastic support for the cream movement guide component 300.

[0110] The spring support 311 can be provided on the lower end side of the inner side of the connecting protrusion 310 and is equipped with a spring insertion groove into which the spring component 500 can be inserted. This serves as a limiter that supports the upper end side by the upper surface of the negative pressure forming space 100a when the cream moving guide component 300 is raised or lowered, thereby limiting the range of raising and lowering movement.

[0111] Furthermore, the upper surface of the negative pressure forming space 100a is provided for the connecting protrusion 310 to pass through and connect, and a lifting guide tube 130 is provided to guide the up and down movement of the connecting protrusion 310. On the upper end side of the connecting protrusion 310, a limiting protrusion 312 is provided to be snapped into the upper end side of the lifting guide tube 130.

[0112] When the cream movement guide component 300 descends, the upper end of the limiting protrusion 312 is engaged with the upper end of the lifting guide tube 130, thereby acting as a limiter to restrict the descent movement range.

[0113] The cream moving guide component 300 rises and falls repeatedly when negative pressure and positive pressure alternate, and rises and falls between the position where the spring support part 311 is engaged with the upper surface of the negative pressure forming space 100a during the rising and falling and the position where the limiting protrusion 312 is engaged with the rising and falling guide tube part 130 during the falling.

[0114] In addition, an O-ring 600 for preventing the flow of therapeutic cream located on the outer side of the connecting protrusion 310 is provided on the inner side of the lifting guide tube 130.

[0115] An O-ring 600 for preventing inflow is provided on the lower end side of the inner side of the lifting guide tube 130, thereby preventing the therapeutic cream from flowing into the inner side of the lifting guide tube 130.

[0116] When negative pressure is generated in the negative pressure forming space 100a, the cream moving guide component 300 will rise with the help of the drawn-in air, i.e., negative pressure, and when negative pressure is generated, it will fall with the help of the air discharged through the suction port 100b, i.e., positive pressure.

[0117] When the cream moving guide component 300 is raised and lowered, the therapeutic cream moving along the outer side of the connecting protrusion 310 will be pushed from the upper side of the negative pressure forming space 100a to the lower side and thereby move more quickly toward the cream receiving part 320.

[0118] After the therapeutic cream is moved to the outer side of the bonding protrusion 310, it can move downward more quickly and smoothly when the cream moving guide 300 is raised and lowered, thereby preventing the problem of stopping and solidifying in a certain part.

[0119] Furthermore, by means of the lifting and lowering movement of the cream moving guide component 300, vibration will occur in the cream receiving portion 320. Therefore, the therapeutic cream that is moving on the upper surface of the cream receiving portion 320, i.e. the first inclined surface 320a, can be moved quickly downward along the first inclined surface 320a by means of vibration and fall back onto the skin.

[0120] The cream movement guide component 300 can move up and down when negative pressure and positive pressure are generated, so that the therapeutic cream that rises along the inner side of the negative pressure forming space 100a toward the suction port 100b can be quickly moved down again and resupplied to the skin. This achieves rapid circulation of the therapeutic cream within the forming space 100a during treatment, so that treatment can be performed without replenishing the therapeutic cream due to loss.

[0121] This invention can prevent therapeutic cream from being sucked into the airflow path by negative pressure during treatment, thereby preventing accidents caused by blockage of the airflow path and ensuring operational stability, as well as the durability of the vacuum device, and saving the cost and time required to repair the airflow path blocked by therapeutic cream.

[0122] This invention can prevent therapeutic cream from being drawn into the airflow path by negative pressure during treatment without a filter, thereby stabilizing the negative and positive pressures at the set pressures during treatment and improving the treatment effect. Moreover, it eliminates the need to replace or manage filters, thus significantly saving the cost and time required for equipment management.

[0123] In the foregoing, the present invention has been described in detail using preferred embodiments; however, the scope of the invention is not limited to the specific embodiments, but should be interpreted in accordance with the appended claims. Furthermore, it should be understood that those skilled in the art can make various modifications and variations without departing from the scope of the invention.
