[0032] Example 1

[0033] like Figures 1 to 9 As shown, the utility model provides a nano-chip for nano-infiltration promotion, including a hollow substrate 1, wherein the bottom array of the hollow substrate 1 has multiple groups of guide sliding cavities 4, and the inner wall of the guide sliding cavity 4 is slidably plugged with a mobile microneedle 7, and the mobile microneedle 7 is penetrated through the bottom of the hollow substrate 1, and the top of the mobile microneedle 7 is connected to a limited pressing block 9, and the top of the limited pressing block 9 is provided with a baffle 10 connected to the inner wall of the hollow substrate 1, and the side wall of the mobile microneedle 7 is provided with a penetration groove 8, and the inner wall of the guide sliding cavity 4 is connected with a sealing plate 6 plugged with the penetration groove 8, and the top of the guide sliding cavity 4 is provided with a conveying chute 5 communicated with the inside of the guide sliding cavity 4, and a quantitative liquid storage space is formed between the conveying chute 5, the upper part of the penetration groove 8 and the sealing plate 6.

[0034] A liquid adding plug 2 is inserted into the side of the hollow substrate 1 . This arrangement facilitates the replenishment of essence liquid to the hollow substrate 1 and can effectively improve the working efficiency of the hollow substrate 1 .

[0035] The side of the hollow substrate 1 is provided with a mounting groove 3 , which makes it easy for the hollow substrate 1 to be connected to external devices and can effectively improve the installation efficiency of the hollow substrate 1 .

[0036] The hollow substrate 1, the guide sliding cavity 4 and the sealing plate 6 are made in one piece. Such a configuration can effectively improve the tightness among the hollow substrate 1, the guide sliding cavity 4 and the sealing plate 6 and can effectively prevent the occurrence of breakage.

[0037] The bottom surface of the guide slide cavity and the bottom surface of the hollow substrate are in the same plane. This arrangement can facilitate the insertion of the mobile microneedle 7 into the skin and can effectively improve the working efficiency and working effect of the mobile microneedle 7.

[0038] The cross-sectional area of ​​the movable microneedle is smaller than that of the limiting pressing block. This arrangement can facilitate the limiting pressing block 9 to seal the opening at the top of the conveying chute 5, effectively improving the working effect of the limiting pressing block 9.

[0039] The working principle of the utility model is as follows: firstly, the hollow substrate 1 is installed on the use device, and then when the nano wafer is used, the essence is first added into the hollow substrate 1, and then the mobile microneedle 7 is inserted into the skin. During the insertion process of the mobile microneedle 7, the mobile microneedle 7 can slide in the guide sliding cavity 4, so that the mobile microneedle 7 is slowly inserted into the stratum corneum of the skin, and the user will not feel pain;

[0040] like Figure 8As shown, the essence in the hollow substrate 1 flows into the quantitative liquid storage space through the top opening of the delivery chute 5. When the moving microneedle 7 contacts the skin, the moving microneedle is forced to slide upward, and the essence in the quantitative liquid storage space flows into the lower space of the penetration groove 8 through the gap between the sealing plate 6 and the penetration groove 8 and flows along the plug-in end of the moving microneedle 7 to the plug-in point of the skin; when the limiting pressing block 9 is separated from the guide sliding cavity 4, the penetration groove 8 moves upward, and the limiting pressing block 9 touches the baffle 10, the essence in the lower space of the penetration groove 8 is inserted into the skin by the moving microneedle 7, and the liquid infiltration is completed.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
