[0006] This invention provides a microneedle application head and beauty device to solve the problem of unstable liquid output in the prior art.

[0007] To achieve the above objectives, the first aspect of this utility model provides a microneedle application head, which adopts the following technical solution:

[0008] A microneedle liquid application head for applying liquid under negative pressure conditions includes a base, the base having a front end face and a liquid outlet channel, the front end face having a protruding ridge and a first liquid outlet hole communicating with the liquid outlet channel, the first liquid outlet hole being disposed adjacent to the protruding ridge, and the area of ​​the front end face excluding the first liquid outlet hole having microneedles.

[0009] Preferably, the protruding ridge includes a straight section or an arc section.

[0010] Preferably, the protruding ridge is composed of multiple segments connected in sequence, and any two adjacent segments of the protruding ridge form an included angle, with the first liquid outlet located within the included angle.

[0011] Preferably, when the protruding ridge is a straight segment, the protruding ridge includes four straight segments connected end to end in sequence, forming four included angles, and the first liquid outlet hole is respectively provided in the four included angles.

[0012] Preferably, when the convex ridge is an arc segment, the arc segment is a closed loop contour with the beginning and end connected, and the first liquid outlet is located within the closed loop area of ​​the arc segment.

[0013] Preferably, the protrusion height of the convex ridge is 0.5mm-0.6mm.

[0014] Preferably, it also includes a second liquid outlet, which is located in the middle of the front end face. The base is provided with a support part, and the second liquid outlet is disposed adjacent to the support part.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The microneedle application head and beauty device provided by this utility model address the issue that, due to differences in skin type and softness among users, some users' skin may become clogged with the first liquid outlet under negative pressure during device use. The negative pressure chamber in this application functions to absorb the skin, while the microneedles pierce the skin. By connecting the liquid outlet channel to the first liquid outlet, the liquid dispensing function is achieved. Furthermore, by providing a raised ridge on the base and placing the first liquid outlet adjacent to the raised ridge, the raised ridge effectively supports the skin during absorption, dispensing, and needle puncture, preventing the skin from clogging the first liquid outlet due to negative pressure. This ensures smooth dispensing and allows different users to receive a uniform liquid volume, thus solving the problem of unstable liquid dispensing.

[0035] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0037] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0038] The following is in conjunction with the appendix Figure 1-10 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0039] Example 1:

[0040] Please refer to Figure 1 This utility model embodiment provides a microneedle application head for applying liquid under negative pressure conditions. It is understood that some beauty devices have a negative pressure adsorption function to adsorb the skin to improve the accuracy of serum application. Specifically, one end of such a beauty device is provided with a negative pressure chamber 1001, and the beauty device is also provided with a negative pressure mechanism 1002. The negative pressure mechanism 1002 usually includes a negative pressure pump and a negative pressure pipe. One end of the negative pressure pipe is connected to the negative pressure pump, and the other end is connected to the negative pressure chamber 1001. The negative pressure pump draws air from the negative pressure chamber 1001 through the negative pressure pipe, thereby adsorbing the skin. The microneedle application head is located in the negative pressure chamber 1001 and accurately applies serum under negative suction conditions.

[0041] Reference Figure 2 and Figure 3 Specifically, the microneedle application head includes a base 1. In this embodiment, the base 1 is generally cylindrical in shape and is installed on the body of the beauty device. One end of the base 1 is exposed outside the body of the beauty device and is used to contact the skin to apply the essence to the skin. For ease of description, the end of the base 1 used for applying the essence is defined as the front end face.

[0042] Meanwhile, to better apply the essence, the base 1 also has a liquid outlet channel 11, and a first liquid outlet hole 12 is provided on the front end face. In addition, the beauty device body has a liquid storage cavity (not shown in the figure) for containing the essence. The liquid outlet channel 11 can adopt a pipe structure. In this case, the interior of the base 1 is hollow, and the liquid outlet channel 11 is located inside the base 1. One end of the liquid outlet channel 11 is connected to the liquid storage cavity, and the other end is connected to the first liquid outlet hole 12. At this time, because the microneedle application head is located in the negative pressure cavity 1001, under the action of negative pressure adsorption, the essence is drawn out from the liquid storage cavity and finally flows out from the first liquid outlet hole 12 through the liquid outlet channel 11, realizing the spray liquid effect. The spray liquid method can make the essence evenly applied to the skin, which is conducive to promoting the absorption of the essence.

[0043] Based on this, since the microneedle applicator needs to apply liquid under negative pressure, and since different users have different skin types, such as some users with softer skin, the first liquid outlet 12 may be blocked by the skin during the process of negative pressure adsorption of the skin, resulting in unstable liquid output of the essence.

[0044] Based on this, continue to refer to Figure 2 and Figure 3 The front surface is also provided with a raised ridge 2, and the first liquid outlet 12 is arranged adjacent to the raised ridge 2. The raised ridge 2 can support the skin under negative suction conditions to prevent it from blocking the first liquid outlet 12, thereby avoiding unstable liquid output. At the same time, in order to facilitate better absorption of the essence by the skin, the area of ​​the front surface excluding the first liquid outlet 12 is provided with microneedles (not shown in the figure). The microneedles can perform microneedling treatment on the skin, thereby bringing the essence into the deeper layers of the skin to promote the absorption of the essence.

[0045] The above-described embodiment solves the problem of unstable liquid output by setting a protruding ridge 2 at the front end of the base 1, which makes the first liquid outlet 12 less likely to be blocked during the application of essence by the microneedle liquid application head under negative pressure. Furthermore, the microneedle's piercing action can further promote the skin's absorption of the essence, thus optimizing and improving the skincare effect.

[0046] Reference Figure 3 In this embodiment, the convex ridge 2 is provided with a straight profile, which is defined here as the straight section 21 of the convex ridge 2. The straight convex ridge 2 structure has a large support profile, which can effectively support the skin and achieve the anti-blocking effect.

[0047] Furthermore, the protruding ridge 2 consists of multiple segments connected sequentially, and the protruding ridge 2 is located at the edge of the front face. For example, the protruding ridge 2 can specifically be two, three, or four segments, and different numbers of protruding ridges 2 can form different overall contours. For example, three straight segments 21 can form a triangular contour, and four straight segments 21 can form a rectangular contour or a trapezoidal contour. The specific number of protruding ridges 2 can be adjusted according to actual needs, and no specific limitation is made here. In this embodiment, four segments of protruding ridge 2 are selected as an example, and the four segments of protruding ridge 2 form a rectangular contour. Here, by setting multiple segments of protruding ridge 2, the support range can be further expanded and the support effect on the skin can be optimized.

[0048] It should be explained that in one embodiment, the multiple convex ridges 2 may not be connected end to end, while in another embodiment, the multiple convex ridges 2 are connected end to end in sequence to form a closed convex ridge 2 outline. Both can provide support, but the closed convex ridge 2 outline can not only provide support for the skin, but also retain the essence between the closed loop of multiple convex ridges 2 to avoid the essence overflowing and being wasted.

[0049] Correspondingly, when there are multiple protrusions 2, the number of first liquid outlet holes 12 can also be set to multiple, and the first liquid outlet holes 12 can be respectively set at adjacent positions of multiple protrusions 2. At this time, by setting multiple first liquid outlet holes 12, the flow rate of essence can be increased, and the uniformity of essence flow can also be improved. The specific number of first liquid outlet holes 12 can be adjusted according to actual needs, and there is no limitation on the specific number of first liquid outlet holes 12.

[0050] In this embodiment, four first liquid outlet holes 12 are specifically provided, and the four first liquid outlet holes 12 are respectively located on the sides of the four protruding ridges 2 to form a rhomboid arrangement outline, thereby improving the liquid output and the uniformity of liquid output. It is understood that in practical applications, multiple first liquid outlet holes 12 can also be provided on the side of the same straight section 21. The number of first liquid outlet holes 12 is not limited here, nor is the specific arrangement method limited. Regardless of the specific combination of the number and arrangement of the protruding ridges 2 and the first liquid outlet holes 12, they should all be included in the scope of interpretation of this application.

[0051] Furthermore, the protrusion height of the ridge 2 is 0.5mm-0.6mm. It is understood that when the height of the ridge 2 is higher than 0.6mm, the microneedles may not be able to effectively stimulate the skin, while when the height of the ridge is less than 0.5mm, the skin may easily block the first fluid outlet 12. Therefore, when the height of the ridge is 0.5mm-0.6mm, better fluid flow and better microneedle puncture effect can be obtained. For example, the specific protrusion height of the ridge 2 can be 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm or 0.6mm. The specific setting range of the ridge 2 can also be limited to any two of the above parameter points. Here, the protrusion height of the ridge 2 is not limited.

[0052] Additionally, refer to Figure 4 To further enhance the application effect of the serum, the microneedle application head also includes a second liquid outlet 3, which is located in the middle of the front end face and is connected to the liquid outlet channel 11. At this time, the second liquid outlet 3 located in the middle of the front end face can further increase the liquid outlet area, and because it is located in the middle of the front end face, it can also apply the serum from the middle of the treatment area to the skin, making the application action more uniform.

[0053] Based on this, to prevent the second liquid outlet 3 from being blocked, the base 1 is also provided with a support part 4, and the second liquid outlet 3 is arranged adjacent to the support part 4. In one embodiment, the support part 4 can also adopt the same structure as the protruding ridge 2, thus providing support for the second liquid outlet 3; in another embodiment, refer to Figure 5 The support part 4 can also be configured as a column structure, and multiple support parts 4 can be configured to surround the second liquid outlet 3. The column structure can also achieve the support function. The specific structure of the support part 4 is not limited here. Regardless of the structural form of the support part 4, the shape and structure that can provide support for the second liquid outlet 3 should be included in the interpretation of the support part 4.

[0054] It should be noted that the microneedles provided in this embodiment are nanoscale microneedle structures, not medical microneedle structures used in acupuncture treatments.

[0055] In one embodiment, the microneedle is fixedly mounted on the base 1. Typically, the microneedle and the base 1 are integrally connected, see reference... Figure 6 Alternatively, mounting holes can be made on the base 1, and one end of the microneedle can be inserted into the mounting hole to achieve fixed installation. There are no restrictions on the specific installation method of the microneedle. By fixing the microneedle on the base 1, it can maintain good connection stability during multiple microneedle treatments.

[0056] Reference Figure 7 In this embodiment, since the number of microneedles is set to multiple, in order to facilitate the fixed installation of multiple microneedles, the base 1 also includes a microneedle chip 5. The microneedle chip 5 is fixed at the front end face, and the microneedles at this time are the microneedles on the microneedle chip 5. Based on the above structural setting, by directly adopting the microneedle chip 5 structure, the difficulty of setting up multiple microneedles is greatly reduced, and the production and assembly are more efficient and convenient.

[0057] It is understood that when the microneedle chip 5 structure is adopted, the first liquid outlet 12 and the second liquid outlet 3 mentioned above can be disposed on the microneedle chip 5. In this case, the microneedle chip 5 should be understood as part of the base 1 and included in the scope of this solution. It is also understood that when the microneedle liquid application head further includes the second liquid outlet 3, the support part 4 can be disposed on the microneedle chip 5, or the support part 4 can be disposed on the base 1, and the microneedle chip 5 is correspondingly provided with clearance holes or clearance grooves to avoid the support part 4.

[0058] Example 2:

[0059] Based on Embodiment 1, features not explained in this embodiment will be explained using the methods described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the arrangement of the first liquid outlet hole 12 is different.

[0060] Reference Figure 8 and Figure 9 In this embodiment, the protruding ridge 2 consists of multiple segments connected in sequence, and any two adjacent protruding ridge segments 2 form an included angle, with the first liquid outlet hole 12 located within the included angle.

[0061] Based on the above structural configuration, the two adjacent protrusions 2 form an angle that can prevent skin from entering. By placing the first liquid outlet 12 within the angle, it provides bilateral support to the skin. Compared with the single-sided support formed by the adjacent protrusions 2 of the first liquid outlet 12 in Embodiment 1, it can better prevent the skin from clogging the first liquid outlet 12, and the anti-clogging effect is further optimized and improved.

[0062] Furthermore, in this embodiment, when the protruding ridge 2 is a straight segment 21, the protruding ridge 2 includes four straight segments 21 connected end to end in sequence, forming four included angles, and a first liquid outlet hole 12 is provided in each of the four included angles; based on the above configuration, a uniform liquid outlet layout can be formed, and the liquid outlet effect is optimized and improved.

[0063] Example 3:

[0064] Based on Embodiment 1, features not explained in this embodiment will be explained using the methods in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the shape of the convex ridge 2 is different.

[0065] Reference Figure 10 Specifically, the convex ridge 2 includes an arc segment 22. The arc segment 22 also has a relatively long support contour, which can also support the skin and achieve an anti-clogging effect.

[0066] Furthermore, when the protruding ridge 2 is an arc segment 22, the arc segment 22 is a closed loop contour with the beginning and end connected. For example, it can be an elliptical contour or a circular contour. In this embodiment, a circular contour is used as an example, and the first liquid outlet 12 is located within the closed loop area of ​​the arc segment 22.

[0067] Based on the above configuration, the closed-loop arc segment 22 is also difficult to be penetrated by the skin. By setting the first liquid outlet 12 within the closed-loop area of ​​the arc segment 22, an anti-clogging effect can be achieved.

[0068] It is understandable that when there are multiple first liquid outlet holes 12, closed-loop arc segments 22 can be respectively provided for each of the multiple first liquid outlet holes 12 to provide anti-clogging support for the multiple first liquid outlet holes 12. Similarly, the support part 4 of the above-mentioned second liquid outlet hole 3 can also be provided as multiple arc segments, or as a closed-loop arc segment.

[0069] Example 4:

[0070] This invention provides a beauty device, including a microneedle liquid application head as described in Embodiment 1, Embodiment 2, or Embodiment 3, and a beauty device body. The microneedle liquid application head is disposed on the beauty device body, resulting in a beauty device with smooth liquid dispensing.

[0071] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
