[0021] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0022] See also Figures 1 to 4 The split multi-needle injection device of the present invention comprises a base 20 and a needle table 10. The base 20 and the needle table 10 are split in design. A receiving groove 21 is provided at one end of the base 20. The needle table 10 is inserted into the receiving groove 21 and is fixed to the receiving groove 21 by glue encapsulation. A plurality of parallel needle grooves 11 are provided on the side of the needle table 10. Needles are fixed in the needle grooves 11 by glue. The other end of the base 20 is connected to the syringe, and the syringe is connected to the needle.

[0023] The split multi-needle injection device of the present invention changes the traditional method of directly vertically inserting and assembling needles through the split design of the base 20 and the needle table 10. The required number of needles are first assembled on the side of the needle table 10, and then the needle table 10 is packaged on the base 20 at one time, which can greatly improve the needle assembly efficiency and assembly accuracy; and the gaps between the needles can be more refined, the spacing between the needles can be shortened, and the pain of injection can be reduced; the number of needles can be adjusted according to the number of needle slots 11, and injection devices with different requirements for the number of needles in different usage scenarios can be produced on demand, which is flexible in production and easy to adapt, thereby improving the applicability of the product.

[0024] A clamping table 23 is provided in the receiving groove 21, and the needle table 10 is supported and positioned on the clamping table 23, which is conducive to the initial positioning and support of the needle table 23 in the receiving groove 21, and is convenient for subsequent fixing with glue. A liquid guide hole 22 is provided in the receiving groove 21, and one end of the needle tube is connected to the liquid guide hole 22, and the other end is exposed in the receiving groove 21. The liquid in the syringe enters the needle tube from the liquid guide hole 22 and is ejected from the other end of the needle tube. The end of the needle tube exposed in the receiving groove 21 is provided with a needle mouth bevel, and the needle mouth bevel of each needle tube is consistent, which is conducive to reducing the pain of injection.

[0025] Specifically, the needle table 10 may be provided with a plurality of parallel needle grooves 11 on only one side, a clamping table 23 is provided on one side of the receiving groove 21, and a liquid guide hole 22 is provided on one side of the clamping table 23. The structure of the needle table 10 having the needle grooves 11 provided on one side is relatively simple, which is conducive to improving production efficiency and has low production cost. The needle table 10 may be provided with a plurality of parallel needle grooves 11 on both sides, a clamping table 23 is provided in the middle of the receiving groove 21, and liquid guide holes 22 are provided on both sides of the clamping table 23. The needle table 10 having the needle grooves 11 provided on both sides can realize the simultaneous assembly of more needle tubes on the same injection device, with a higher density of needle tubes, which can meet more usage scenarios requiring needle tubes.

[0026] The needle groove 11 adopts a V-shaped slope design, and the needle tube can be automatically initially positioned when it falls into the needle groove 11, which can effectively reduce the difficulty of needle tube assembly and improve assembly efficiency and positioning accuracy.

[0027] A glue groove 12 is also provided in the middle of the side of the needle table 10. The glue groove 12 and the needle groove 11 are located on the same side, and the glue groove 12 is connected to the needle groove 11. On the one hand, it is beneficial to increase the bonding area between the needle table 10 and the inner wall of the accommodating groove 21 when the needle table 10 is fixed to the accommodating groove 21, thereby improving stability. On the other hand, it is beneficial to strengthen the fixation of the needle tube to the needle table 10.

[0028] The shape and size of the needle table 10 match those of the receiving groove 21 , which is beneficial for the needle table 10 to be inserted into the receiving groove 21 for initial positioning and clamping, so as to facilitate the subsequent glue dispensing and fixing to proceed more smoothly.

[0029] The needle tubes are arranged parallel to the needle table 10, and the length of each needle tube exposed from the needle table 10 is equal, and the length of each needle tube exposed from the receiving groove 21 is equal, and the length of the needle tube exposed from the receiving groove 21 is 0.5mm-5mm, so as to reduce the pain of injection.

[0030] The needle table 10 is completely sunken into the receiving groove 21 and is fixed to the receiving groove 21 by glue packaging. An auxiliary groove 24 is formed between the glue packaging plane 241 and the outlet of the receiving groove 21 to assist in raising the skin bump. The skin is directly raised by squeezing the skin through the auxiliary groove 24, which reduces the labor intensity and pain of injection and improves the user experience of the injection operator.

[0031] Two symmetrical side surfaces of the base 20 are provided with two flying wings 26, and the other side surface is provided with a central indicator plate 25 for touching and locating the direction of the needle tube.

[0032] Compared with the prior art, the split multi-needle injection device of the present invention has changed the traditional process of directly inserting and assembling needles vertically through the split design of the base 20 and the needle table 10. The required number of needles are first assembled on the side of the needle table 10, and then the needle table 10 is packaged on the base 20 at one time, which can greatly improve the needle assembly efficiency and assembly accuracy, greatly change the traditional injection molding method of ultra-fine deep hole injection molds, and avoid the problem of broken needles in ultra-fine deep hole injection molds; and the gaps between the needles can be more refined, the spacing between the needles can be reduced, the liquid output per unit area can be increased under the same pressure, and the injection pain can be reduced; the number of needles can be adjusted according to the number of needle slots 11, and injection devices with different requirements for the number of needles in different usage scenarios can be produced on demand, which is flexible in production and easy to adapt. Improve product applicability; the needle groove 11 adopts a V-shaped slope design, and the needle tube can be automatically initially positioned when it falls into the needle groove 11, which can effectively reduce the difficulty of needle tube assembly and improve assembly efficiency and positioning accuracy; the length of each needle tube exposed from the accommodating groove 21 is equal, and the length of the needle tube exposed from the accommodating groove 21 is 0.5mm-5mm, which is conducive to reducing injection pain; an auxiliary groove 24 is formed between the glue packaging plane 241 and the mouth of the accommodating groove 21 to assist in skin bump formation. The skin is squeezed by the auxiliary groove 24 to directly form a skin bump, which reduces the labor intensity and pain of injection and improves the user experience of the injection operator.
