Description
本发明涉及无针注射技术领域，尤指一种无针水光注射装置。
在将药物、美容产品等导入人体时，一般分为有针注射和无针注射，其中，在美容行业，若注射时产生破皮，风险很大，所以都采用无针导入技术。无针注射是一种没有传统毛细管针头的注射方式，它不需要通过针头扎入肉体，而是由无针注射推动器产生一定的压力，在压力作用下推动药液，弥散注入患者的皮下组织，因此也会一定程度上减少患者针扎肉刺的痛苦与恐惧。
但是，现有的用于美容行业的无针注射器大多只有产生高压气流的注射结构，很难做到精密的定量注射，且无法精准的在真皮层深下定点、定位，不利于药液的渗透，影响美容的效果，同时，现有的无针注射器只能一定程度上减少用户的疼痛，并不能较大的缓解注射疼痛，影响用户的使用体验。因此，需要一种能够较好的缓解注射疼痛，且能够精准的在真皮层深下定点、定位，实现定量注射的无针水光注射装置，以提高注射液体的美容效果和用户的使用体验。
发明内容
本发明的目的是提供一种无针水光注射装置，该无针注射器能够较好的缓解注射疼痛，且能够精准的在真皮层深下定点、定位，有利于药液的渗透，实现定量注射，从而提高注射液体的美容效果和用户的使用体验。
本发明提供的技术方案如下：
本发明提供一种无针水光注射装置，包括：
枪体，所述枪体内设置有容纳腔；
注射管，设置在所述枪体的前端，用于存储待注射液体；
注射驱动结构，设置在所述容纳腔内，并通过推液杆与所述注射管连接，用于注射所述注射管内的待注射液体；
负压冷冻结构，套设在所述注射管的前端，用于在所述注射管的注射口和人体皮肤之间形成负压并降温；
敲击破壁结构，设置在所述容纳腔内，并与所述注射管的管壁连接，用于通过所述注射管和所述负压冷冻结构向人体皮肤传递低频振动。
通过在枪体的前端设置注射管，在枪体的容纳腔内设置注射驱动结构，能够实现注射管内待注射液体的注射；通过在注射管的前端设置负压冷冻结构，能够在注射时，在注射口和人体皮肤之间形成负压环境并降温，从而便于皮肤的吸附和液体的注射，同时，低温也能够较好的缓解注射疼痛，避免影响使用者的使用体验；此外，通过在容纳腔内设置敲击破壁结构，能够在注射前，以特定频率向人体皮肤传递低频振动，有利于精准的在真皮层深下定点、定位，有利于药液的渗透，实现药液的定量注射，从而提高注射液体的美容效果。
具体的，装置在使用时，首先在注射管内注入待注射液体，如玻尿酸等；之后将负压冷冻结构套设在注射管的前端，并将负压冷冻结构的端口紧贴人体皮肤；然后便可以通过敲击破壁结构进行敲击破壁，以及通过负压冷冻结构使射管的注射口和人体皮肤之间形成负压并降温；最后便可以通过注射驱动结构进行待注射液体的注射，完成无针注入过程。
进一步地，所述敲击破壁结构包括固定在所述容纳腔内的第一驱动装置，
所述第一驱动装置的输出端连接有锤体，所述锤体的侧方设置有固定在所述容纳腔侧壁上的振动块，
所述枪体和所述注射管之间设置有固定块，所述固定块固定在所述枪体的前端面；
