Abstract

This utility model discloses a beauty component and a beauty device. The beauty component includes: a main body with a liquid outlet channel inside, and a positioning recess on one side wall of the main body for accommodating an external container; and a pin disposed in the positioning recess, the pin having an air inlet and an outlet communicating with one end of the liquid outlet channel on its surface. The height of the air inlet is higher than the height of the outlet in the height direction of the pin. The beauty component of this utility model engages with the external container via its pin.

Description

Technical Field

[0001] This utility model relates to the field of beauty instrument technology, and in particular to a beauty component and a beauty instrument. Background Technology

[0002] Aqua-light beauty devices are beauty devices that use microneedling or high-pressure jet technology to precisely deliver beauty ingredients such as hyaluronic acid, vitamins, and collagen to the deep layers of the skin. The core mechanism is to use microneedles to break through the skin barrier, allowing nutrients to act directly on the dermis, thereby achieving effects such as deep hydration, anti-aging repair, and brightening of skin tone, significantly improving skin hydration and radiance.

[0003] In related technologies, one type of beauty device adopts a modular design, with its main structure equipped with a needle that fits into a vial (a typical serum container). This needle integrates a dual-path structure of liquid outlet and air inlet channels. When the vial is installed on the main body of the beauty device, the needle penetrates the stopper to form a physical connection, simultaneously facilitating the liquid outlet and air inlet paths between the vial's inner cavity and the device's interior. During operation, the device is driven by an air pressure control system (positive or negative pressure), causing the serum in the vial to be exported through the needle's outlet channel and directed to the beauty head equipped with a microneedle array or jet component, completing the ingredient introduction.

[0004] However, in actual use, due to factors such as hand-held operation shaking, vibration of the instrument's own power system, and the composition of the essence, air bubbles are easily generated in the vial during the air intake and liquid output process. These air bubbles can easily cover the outlet and air inlet on the needle, causing abnormal conduction of the originally independent air-liquid pathway. At this time, the air pressure applied by the air pressure control system cannot effectively act on the liquid medium, causing the air pressure to fail, which in turn leads to poor or even interrupted essence delivery, affecting the use of the instrument. Utility Model Content

[0005] The main purpose of this utility model is to propose a beauty component for a beauty device, which aims to solve to some extent the technical problem of poor or even interrupted delivery of essence caused by air bubbles in the essence bottle in current beauty device equipment.

[0006] To achieve the above objectives, this utility model proposes a beauty component for a beauty device, the beauty component of which includes:

[0007] The main body has a liquid outlet channel inside, and a positioning recess for accommodating an external container is provided on one side wall of the main body.

[0008] The insertion pin is disposed in the positioning recess. The surface of the insertion pin is provided with an air inlet and an outlet communicating with one end of the liquid outlet channel. In the height direction of the insertion pin, the height of the air inlet is higher than the height of the outlet.

[0009] Optionally, the pin includes a pointed cone portion, and the air inlet is formed on the pointed cone portion.

[0010] Optionally, the outlet is located near the bottom surface of the pointed cone.

[0011] Optionally, the pointed cone has a beveled surface, the beveled surface forming a notch from top to bottom, and the outlet is located on the bottom surface of the notch.

[0012] Optionally, the pin further includes a column, the pointed portion is connected to one end of the column, and the other end of the column is connected to the bottom surface of the positioning recess.

[0013] Optionally, the number of air inlets is provided to be at least two, and the at least two air inlets and the outlet are arranged around the central axis of the pin.

[0014] Optionally, the inner wall of the positioning recess is provided with a boss, which is used to restrict the external container from detaching from the positioning recess.

[0015] Optionally, the beauty components of the beauty device further include:

[0016] A beauty head is located at one end of the main body and is used for skin care. The side of the beauty head facing the skin has a liquid outlet, which is connected to the other end of the liquid outlet channel.

[0017] Optionally, a negative pressure space is formed on the side of the beauty head facing the skin, and the negative pressure space is in communication with the liquid outlet.

[0018] The beauty device includes a negative pressure mechanism, and the main body is also provided with an air intake channel. One end of the air intake channel is connected to the negative pressure space, and the other end is connected to the negative pressure mechanism. The air inlet is connected to the atmosphere.

[0019] This utility model also proposes a beauty device, which includes a beauty device body and beauty components as described above, wherein the beauty components are disposed at one end of the beauty device body.

[0020] The beauty component of this utility model of a beauty device accommodates an external container through a positioning recess on its main body. The pin in the positioning recess forms an insertion fit with the external container. There is a height difference between the outlet and the air inlet on the pin in the height direction of the pin. Even if the container generates air bubbles due to various factors, the existence of this height difference reduces the probability that the outlet and the air inlet will be covered by air bubbles at the same time. This reduces the probability of abnormal conduction between the liquid outlet channel and the air inlet channel affecting the liquid outlet, thereby improving the stability of the liquid flow through the outlet when the air pressure control system is working. This greatly solves the problem of air pressure liquid conduction failure caused by abnormal conduction of the gas-liquid passage, and realizes stable liquid delivery. Attached Figure Description

[0031] This utility model embodiment proposes a beauty component 100 for a beauty device, referring to... Figures 1 to 4 The beauty components 100 of the beauty device include:

[0032] The main body 110 has a liquid outlet channel inside, and a positioning recess 110Q for accommodating an external container 200 is provided on one side wall of the main body 110.

[0033] The pin 120 is disposed in the positioning recess 110Q. The surface of the pin 120 is provided with an air inlet 1201 and an outlet 1202 that communicates with one end of the liquid outlet channel. In the height direction of the pin 120, the height of the air inlet 1201 is higher than the height of the outlet 1202.

[0034] The beauty component 100 involved in this embodiment is applied to a beauty device. That is, the beauty component 100 is a component of the beauty device's structure. It can be integrated into the beauty body of the beauty device (non-removable and replaceable), or it can be detachably connected to the beauty body of the beauty device (removable and replaceable) for repair or replacement. The beauty device involved can be a water-light beauty device, including but not limited to this.

[0035] In some embodiments, the beauty component 100 comprises a main body 110 and a pin 120. The main body 110 may be elongated, but is not limited to this shape. Depending on the structural design, when the beauty component 100 is detachable in the beauty device, the main body 110 may be a component existing independently of the main body of the beauty device; when the beauty component 100 is non-detachable in the beauty device, a component in the main body of the beauty device may be used as the main body 110, such as the shell of the beauty device. The main body 110 has a liquid outlet channel inside, which is used to transfer liquids such as beauty essence. One side wall of the main body 110 has a positioning recess 110Q, which may be formed by a partial recess of one side wall of the main body 110. The inner wall shape of the recess matches the outer wall shape of the outer container 200, such as the cylindrical mouth of a vial. The positioning recess 110Q may be a cylindrical groove. The positioning recess 110Q is used to receive the outer container 200, which is inserted into the positioning recess 110Q through its bottle mouth end to achieve positioning and installation on the main body 110. The outer container 200 can be a common serum container 200 such as a vial, including but not limited to this.

[0036] In some embodiments, the pin 120 is disposed in the positioning recess 110Q, specifically on the bottom surface of the positioning recess 110Q. The surface of the pin 120 is provided with an air inlet 1201 and an outlet 1202. The outlet 1202 communicates with one end of the liquid outlet channel inside the main body 110, allowing the liquid in the external container 200 to enter the liquid outlet channel through the outlet 1202 and then be delivered to subsequent components of the beauty device, such as the beauty head 130, for application to the skin via the beauty head 130. The air inlet 1201 is used for air intake; gas enters the container 200 through the air inlet 1201 to act on the liquid, causing the liquid to flow out through the outlet 1202. The air pressure control system of the beauty device can be a negative pressure system or a positive pressure system. When a negative pressure system is used, the negative pressure system is connected to the liquid outlet channel, while the air inlet 1201 is connected to the atmosphere. By drawing negative pressure, the liquid in the container 200 is drawn out through the outlet 1202. When a positive pressure system is used, the positive pressure system is connected to the air inlet 1201. By applying positive pressure, the liquid in the container 200 is squeezed out through the outlet 1202. Both air pressure systems mentioned above are compatible with the beauty component 100 of this solution, and this embodiment does not limit them.

[0037] When the external container 200 (such as a vial) is installed in the positioning recess 110Q of the main body 110, the pin 120 penetrates the stopper of the container 200, forming a physical connection with the inside of the container 200, thereby opening the liquid outlet channel and air inlet path between the inner cavity of the container 200 and the inside of the main body 110.

[0038] Under normal operating conditions, the liquid in container 200 is at the bottom, and the gas is at the top. When bubbles are generated in container 200 due to hand-held shaking, vibration of the instrument's power system, or the composition of the essence, the bubbles will float upwards because their density is less than that of the liquid. Since the height of the air inlet 1201 is higher than that of the outlet 1202, the outlet 1202 is at a relatively lower position and the air inlet 1201 is at a relatively higher position along the height direction of the needle 120. As a result, even if bubbles are generated, they tend to accumulate in the area above the needle 120, near the air inlet 1201, while the area below the outlet 1202 remains covered by liquid. Therefore, the probability of both the outlet 1202 and the air inlet 1201 being covered by bubbles simultaneously is reduced, thereby reducing the possibility of abnormal connection between the liquid outlet channel and the air inlet channel.

[0039] When the pneumatic control system is working, whether positive or negative pressure is applied, the gas entering the container 200 through the inlet 1201 can effectively act on the liquid. Under positive pressure, the gas pushes the liquid through the outlet 1202 into the liquid outlet channel; under negative pressure, the liquid is drawn into the liquid outlet channel through the outlet 1202 under the action of the pressure difference, thereby achieving stable liquid delivery, avoiding situations where liquid delivery is obstructed or even interrupted, and ensuring the normal operation of the instrument.

[0040] In some embodiments, refer to Figure 5 The insert 120 includes a pointed cone portion 121, and an air inlet 1201 is formed in the pointed cone portion 121. In this embodiment, the insert 120 has a structural design with a pointed cone portion 121, and the air inlet 1201 is cleverly arranged in the pointed cone portion 121. The pointed cone portion 121 has a sharp shape that is narrow at the top and wide at the bottom. Its tip can concentrate force with a small contact area, which greatly reduces the resistance when penetrating the bottle stopper. At the same time, the inclined sidewall of the pointed cone portion 121 can guide the bottle stopper material to be evenly distributed in all directions during the insertion process, avoiding problems such as bottle stopper breakage and debris falling off due to excessive local stress, and ensuring the cleanliness and sealing of the container 200. The air inlet 1201 is set in the pointed cone portion 121, which matches the trajectory of the rising air bubbles, making it easier for the air bubbles to gather in the air inlet 1201 area, further increasing the spatial distance between the air inlet and outlet 1202, reducing the probability that both are covered by air bubbles at the same time, ensuring the stability and independence of the gas-liquid passage, and improving the efficiency and stability of gas pressure liquid conduction.

[0041] In some embodiments, refer to Figure 5The outlet 1202 is located near the bottom surface of the cone portion 121. The bottom surface of the cone portion 121 serves as the area where the needle 120 contacts the liquid inside the container 200 and is relatively close to the lower end. The outlet 1202 is located here, allowing the liquid outlet to be positioned lower. This ensures that even in the later stages of liquid use, when a small amount of liquid remains in the container 200, the outlet 1202 remains submerged in the liquid, maintaining a stable liquid output, reducing liquid residue, and improving liquid utilization. Simultaneously, the outlet 1202, located near the bottom surface, forms a larger vertical distance from the air inlet 1201, which is located higher on the cone portion 121, further reducing the possibility of abnormal gas-liquid passage flow.

[0042] In some embodiments, refer to Figure 5 The pointed cone portion 121 has a beveled surface, forming a notch 121K from top to bottom. The outlet 1202 is located on the bottom surface of the notch 121K. In this embodiment, the pointed cone portion 121 of the insert 120 is specially designed to have a beveled surface. This beveled surface extends from the top of the pointed cone portion 121 to the bottom, forming a notch 121K structure. The outlet 1202 is precisely positioned on the bottom surface of the notch 121K. The presence of the beveled surface changes the outer contour of the pointed cone portion 121, allowing the beveled surface to slide and compress more smoothly with the stopper material when the insert 120 is inserted into the stopper of the container 200. At the same time, the notch 121K structure creates a relatively independent liquid gathering area in the pointed cone portion 121, facilitating the stable flow of liquid into the outlet 1202. In addition, the edge of the notch 121K is formed with a corresponding ridge. When the pin 120 is inserted into the stopper of the container 200, the ridge acts as a cutting edge to further break the structure at the stopper, making the breaking action simpler and more efficient.

[0043] In some embodiments, refer to Figure 5 The needle 120 also includes a column 122, with a pointed cone 121 connected to one end of the column 122, and the other end of the column 122 connected to the bottom surface of the positioning recess 110Q. The column 122 and the pointed cone 121 can be manufactured using an integral molding process. When the needle 120 is inserted into the stopper of the container 200, the pointed cone 121 penetrates the stopper, while the circumferential side of the column 122 is press-fitted with the stopper hole wall, effectively sealing the gap between the needle 120 and the stopper, preventing liquid leakage and the entry of outside air into the container 200, ensuring the normal operation of the beauty device. In this embodiment, the column 122 makes the structure of the needle 120 more complete, better supporting the pointed cone 121, ensuring the relative position stability of the air inlet 1201 and the outlet 1202, further optimizing the structure of the gas-liquid passage, and improving the efficiency and stability of liquid delivery.

[0044] In some embodiments, refer to Figure 5The device has at least two air inlets 1201, and these two air inlets 1201 and outlets 1202 are arranged around the central axis of the pin 120. In this embodiment, the arrangement of multiple air inlets 1201 increases the channels for gas to enter the container 200, allowing gas to enter the container 200 more quickly and evenly, improving the response speed and efficiency of the air pressure control system, and ensuring that the liquid can be stably and continuously discharged. Furthermore, the surrounding layout ensures that the air inlets 1201 and outlets 1202 are evenly distributed around the circumference of the pin 120, forming a multi-channel gas-liquid transport structure. Specifically, the multiple air inlets 1201 are arranged in a ring array around the central axis of the pin 120, which can create a uniform air pressure distribution within the container 200, avoiding unstable liquid flow caused by excessively high or low local air pressure, further improving the stability and uniformity of the essence delivery. The outlets 1202 are also arranged in appropriate positions around the central axis, ensuring that the gas-liquid pathways operate independently and efficiently.

[0045] In some embodiments, refer to Figure 2 The inner wall of the positioning recess 110Q is provided with a boss 110T, which is used to prevent the outer container 200 from disengaging from the positioning recess 110Q. The boss 110T is arranged circumferentially along the positioning recess 110Q and can be a ring-shaped protrusion, multiple spaced block protrusions, or other limiting structures. The position of the boss 110T corresponds to the bottle mouth end of the outer container 200, and its height and shape are adapted to the outer wall contour of the container 200 to prevent the container 200 from disengaging from the positioning recess 110Q, ensuring that the container 200 is stably connected to the pin 120 after installation.

[0046] In some embodiments, refer to Figure 1 The beauty components 100 of the beauty device also include:

[0047] A beauty head 130 is located at one end of the main body 110 and is used for skin care. The side of the beauty head 130 facing the skin has a liquid outlet 131, which is connected to the other end of the liquid outlet channel.

[0048] The beauty head 130 is located at one end of the main body 110. As a key component that directly contacts the skin and performs skincare, it has a liquid outlet 131 on the side facing the skin. The liquid outlet 131 is connected to the other end of the liquid outlet channel inside the main body 110, thus forming a complete essence delivery path. The beauty head 130 may have a guide channel inside, connecting the liquid outlet channel and the liquid outlet 131, to ensure that the essence delivered from the liquid outlet channel can be evenly and smoothly discharged from the liquid outlet 131 and applied to the skin surface.

[0049] Specifically, when the air pressure control system is working, gas enters the container 200 through the air inlet 1201. Under the action of air pressure, the essence in the container 200 flows into the liquid outlet channel of the main body 110 through the outlet 1202 of the needle 120, and then is transported to the inside of the beauty head 130 along the liquid outlet channel. Guided by the flow channel inside the beauty head 130, the essence is evenly discharged from the liquid outlet 131 facing the skin. The beauty head 130, in conjunction with its own care functions (such as microneedling, vibration massage, radio frequency heating, etc.), accurately delivers the essence into the deep layers of the skin to achieve skin care.

[0050] In some embodiments, the liquid outlet channel inside the main body 110 includes an integrated pipe structure designed as a single unit with the main body 110, or an independent pipe structure assembled inside the main body 110, or a combination of both.

[0051] In some embodiments, refer to Figure 1 A negative pressure space 132 is formed on the side of the beauty head 130 facing the skin, and the negative pressure space 132 is connected to the liquid outlet 131.

[0052] The beauty device includes a negative pressure mechanism, and the main body 110 is also equipped with an air intake channel. One end of the air intake channel is connected to the negative pressure space 132, and the other end is connected to the negative pressure mechanism. The air inlet 1201 is connected to the atmosphere.

[0053] When the negative pressure mechanism is working, it draws air from the negative pressure space 132 through the suction channel, creating a negative pressure environment in the negative pressure space 132. Under this negative pressure, the liquid in the container 200 flows into the liquid outlet channel of the main body 110 through the outlet 1202 of the needle 120, and then is transmitted to the beauty head 130 along the liquid outlet channel. It is then discharged into the negative pressure space 132 through the liquid outlet hole 131 and applied to the skin. At the same time, the air inlet 1201, which is connected to the atmosphere, introduces air into the container 200 to ensure the stable balance of air pressure in the container 200 and to avoid abnormal air pressure in the container 200 due to the operation of the negative pressure mechanism, which would affect the normal delivery of the essence.

[0054] In some embodiments, the air intake channel inside the main body 110 includes an integrated pipe structure designed as a single unit with the main body 110, or an independent pipe structure assembled inside the main body 110, or a combination of both.

[0055] In some embodiments, the main body 110 is hollow inside, and a through hole communicating with the atmosphere is opened on any wall of the internal space of the main body 110, and the air inlet 1201 communicates with the atmosphere through the internal space of the main body 110. Alternatively, by providing an integrated pipe or an independent pipe communicating with the atmosphere in the main body 110, the air inlet 1201 communicates with the atmosphere through the integrated pipe or the independent pipe.

[0056] This utility model embodiment also proposes a beauty device, see reference Figure 6 The beauty device includes a beauty device body 300 and a beauty component 100 as described in the foregoing embodiments. The beauty component 100 is disposed at one end of the beauty device body 300. The specific structure of the beauty component 100 is as described in the foregoing embodiments. Since this beauty device adopts all the technical solutions of all the foregoing embodiments, it has at least all the technical effects brought about by the technical solutions of the foregoing embodiments, and will not be described in detail here. In this embodiment of the beauty device, the beauty component 100 and the beauty device body 300 have two implementation forms in terms of the setting method. One is a detachable connection. The beauty component 100, as an independent module, can be quickly installed and removed from the beauty device body 300 through connection structures such as threads, buckles, and magnetic attraction. This makes it convenient for users to replace different types of beauty components 100 according to different skin care needs, or to perform deep cleaning and maintenance on the beauty component 100, such as... Figure 6 As shown, one end of the beauty device body 300 is provided with an installation cavity. The beauty component 100 is inserted into the installation cavity through its main body 110 and is detachably connected to the beauty device body 300. Furthermore, one side of the beauty device body 300 is provided with a clearance opening communicating with the installation cavity. This clearance opening is aligned with a positioning recess 110Q on the main body 110. The external container 200 passes through this clearance opening and is inserted into the positioning recess 110Q on the main body 110. Secondly, it is an integrated unit. The main body 110 of the beauty component 100 and the beauty device body 300 are formed into a non-detachable integral structure through injection molding, welding, and other processes, ensuring the structural stability and sealing of the beauty device during use. Beauty devices come in a variety of types, with typical applications including hyaluronic acid injection devices, but they are also suitable for other beauty devices requiring serum infusion functions.
