Description

Technical Field

[0001] The utility model relates to the technical field of introducers, in particular to a novel handle structure of a microcurrent introducer. Background Art

[0002] In the existing introducer, essence flows from a syringe to an introduction head through an external tube. The disadvantages of this solution are as follows:

[0003] 1. A considerable part of the essence will remain in the tube, resulting in waste of the essence, and the essence remaining in the introduction head and the tube is prone to breeding bacteria;

[0004] 2. Since the external tube and the introduction head are integrated, and the electrodes in the introduction head are integrally injection-molded with the introduction head, the service life of the introduction head is very short, and the introduction head needs to be frequently replaced, which is not conducive to environmental protection;

[0005] 3. The external tube will block the operator's line of sight during actual operation, and there is a certain probability of contacting the customer's skin, bringing a bad experience to the customer and causing trouble to the operator;

[0006] For the above reasons, we propose a novel handle structure of a microcurrent introducer. Content of the Utility Model

[0007] The purpose of the utility model is to provide a novel handle structure of a microcurrent introducer to solve the problems raised in the above background art.

[0008] To achieve the above purpose, the utility model provides the following technical solution: A novel handle structure of a microcurrent introducer, including a syringe, a handle shell, a propulsion motor and an introduction head. The handle shell is composed of a lower handle shell and an upper handle shell, and the lower handle shell and the upper handle shell are snap-fitted and installed together. A propulsion motor is arranged in the middle of the handle shell, and an installation groove is arranged between the lower handle shell and the upper handle shell, and the propulsion motor is fixed therein through the installation groove;

[0009] The syringe is snap-fitted in the front side of the inner cavity of the handle shell, and the rear end of the syringe is connected to the transmission end of the propulsion motor; The front end of the handle shell is snap-fitted and fixed with an insulating flange, a silica gel sealing tube is inserted through the middle of the insulating flange, and conductive spring pins are symmetrically installed on the left and right sides of the insulating flange from back to front;

[0010] A leading head is provided on the front side of the insulating flange. The leading head includes an electrode circuit board, a leading head housing, and a leading head electrode. Five mounting holes are provided on the front side of the leading head housing. Leading head electrodes are provided in the four outer mounting holes, and a liquid outlet head is provided in the middle mounting hole. The liquid outlet head communicates with a silica gel sealing tube at the back, and the silica gel sealing tube communicates with a syringe at the back.

[0011] Furthermore, a ring-shaped mounting head is provided at the front end of the insulating flange, and a sealing gasket is provided on the mounting head. The leading head housing is plugged into the mounting head at the back and is friction-fixed by the sealing gasket.

[0012] Furthermore, the electrode circuit board is installed in the inner cavity of the leading head housing from back to front, and fixing screws are provided between the four corners of the electrode circuit board and the inner cavity of the leading head housing for fixation.

[0013] Furthermore, the four fixing screws fix the electrode circuit board and the leading head electrodes on the leading head housing from back to front and form the leading head. When installed, the leading head housing is sleeved on the insulating flange at the back. After the sleeved installation, the conductive spring pins are electrically connected to the electrode circuit board and the leading head electrodes, and the liquid outlet head communicates with the syringe.

[0014] Furthermore, a control host is connected to the outside of the handle housing. A motor control line is connected between the control host and the propulsion motor, and an energy output line is connected between the control host and the two conductive spring pins.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1) The excellent sealing design enables the essence liquid in the syringe to directly flow to the liquid outlet of the leading head through the silica gel sealing tube. The left end of the silica gel sealing tube is flexibly combined with the leading head housing. The conductive spring pins are connected to the micro-current of the control host through the energy output line, and can continuously and stably supply power to the leading head electrodes. Almost no residue remains in the entire essence liquid channel, and there is almost no delay during the liquid outlet process.

[0017] 2) The structure is simple and easy to use. For the leading head, only plugging and unplugging actions are required to connect or disconnect the conductive spring pins from the electrode circuit board, realizing flexible micro-current access. Moreover, as long as the consumable electrode circuit board is replaced occasionally, the leading head can be reused, avoiding waste of consumables and reducing the later use cost.

[0018] 3) Since there are no external tubes, the overall consistency of the handle is very good, there is no problem of blocking the line of sight, and the handle is more beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Embodiment:

[0027] Please refer to Figures 1-4 , the present utility model provides a technical solution for a new handle structure of a microcurrent introduction instrument: including a syringe 1, a handle shell, a propulsion motor 14 and an introduction head. The handle shell is composed of a lower handle shell 2 and an upper handle shell 11. The lower handle shell 2 and the upper handle shell 11 are buckled and installed inwardly together. A propulsion motor 14 is arranged in the middle of the handle shell. An installation groove is arranged between the lower handle shell 2 and the upper handle shell 11, and the propulsion motor 14 is fixed therein through the installation groove;

[0028] The front side of the inner cavity of the handle shell is clamped with a syringe 1, and the rear end of the syringe 1 is connected to the transmission end of the propulsion motor 14; the front end of the handle shell is clamped and fixed with an insulating flange 3. A silicone sealing tube 10 is inserted through the middle of the insulating flange 3. Conductive spring needles 4 are symmetrically installed on the left and right sides of the insulating flange 3 from back to front;

[0029] An introduction head is provided on the front side of the insulating flange 3. The introduction head includes an electrode circuit board 5, an introduction head housing 6, and an introduction head electrode 7. Five mounting holes are provided on the front side of the introduction head housing 6. The introduction head electrodes 7 are provided in the four outer mounting holes, and a liquid outlet head 8 is provided in the middle mounting hole. The liquid outlet head 8 communicates with the silica gel sealing tube 10 at the back, and the silica gel sealing tube 10 communicates with the syringe 1 at the back.

[0030] The front end of the insulating flange 3 is provided with an annular mounting head, and a sealing washer is provided on the mounting head. The introduction head housing 6 is plugged into the mounting head at the back and is friction-fixed through the sealing washer. Grasp the introduction head housing 6 and pull it forward, and the introduction head can be separated from the insulating flange 4 to achieve flexible disassembly.

[0031] The electrode circuit board 5 is installed in the inner cavity of the introduction head housing 6 from the back to the front, and fixing screws 9 are provided between the four corners of the electrode circuit board 5 and the inner cavity of the introduction head housing 6 for fixing.

[0032] The four fixing screws 9 fix the electrode circuit board 5 and the introduction head electrode 7 on the introduction head housing 6 from the back to the front and form the introduction head. Removing the introduction head housing 6 can quickly complete the replacement of the electrode circuit board 5 without replacing the entire introduction head, saving the waste of consumables and reducing the use cost.

[0033] During installation, the introduction head housing 6 is sleeved on the insulating flange 3 at the back. After the sleeve installation, the conductive spring needle 4 is electrically connected to the electrode circuit board 5 and the introduction head electrode 7, and the liquid outlet head 8 communicates with the syringe 1.

[0034] A control host is connected outside the handle housing. A motor control line 13 is connected between the control host and the propulsion motor 14, and an energy output line 12 is connected between the control host and the two conductive spring needles 4. Controlling the propulsion motor 14 to push the syringe 1 forward at a constant speed can push the essence liquid in the syringe 1 forward.

[0035] When this solution is in use, the front end of the insulating flange 3 is combined with the introduction head housing 6, the silica gel sealing tube 10 is combined with the syringe 1 to form an essence liquid channel. The conductive spring needle 4 is made of metal, and the micro-current access between the control host and the introduction head is completed through flexible plugging. When installed forward, it forms an electrical connection relationship with the electrode circuit board 5 and the introduction head electrode 7 to access the micro-current for the introduction head electrode 7.

[0036] The electrode circuit board 5 and the conductive spring needle 4 form a current channel, and the silica gel sealing tube 10 and the syringe 1 form an essence liquid channel. The two channels intersect within the introduction head housing 6. The electrode circuit board 5 utilizes the principle that like charges repel and opposite charges attract. When the essence liquid with active particle components encounters an electrode with the same polarity as it, its movement speed will increase and intensify, so that it can penetrate into the skin faster through the pores, sweat glands and cell gaps of the skin; promoting skin absorption, thus achieving a better beauty effect.

[0037] Preferably, the electrode circuit board 5 is installed inside the introduction head housing 6. When replacing, only the electrode circuit board 5 needs to be disassembled and replaced separately, without replacing the entire introduction head, which is very convenient.
