[0026] Embodiment 1

[0027] As Figures 1 - 2 shown, in this embodiment, an applicator is provided, which mainly includes an extrusion cylinder body, an extrusion mechanism, and an extrusion head 8. A storage cavity 5 is arranged inside the extrusion cylinder body, and the storage cavity 5 is used to store ointment. The extrusion head 8 is arranged at one end of the extrusion cylinder body and is communicated with the storage cavity 5. The extrusion mechanism is arranged at the end of the extrusion cylinder body far from the extrusion head 8 and can push the ointment in the storage cavity 5 to extrude the ointment from the extrusion head 8. Among them, a transparent part is further arranged on the storage cavity 5, and the transparent part extends along the length direction of the storage cavity 5 to facilitate observing the storage amount of the ointment in the storage cavity 5. And a scale ruler 6 is arranged on the transparent part to facilitate observing the extrusion amount of the ointment. An application nozzle 9 is further arranged on the extrusion head 8. A ointment outlet is arranged on the application nozzle 9 for extruding the ointment, and the application nozzle 9 can apply the ointment.

[0028] In this embodiment, a transparent part is arranged on the storage cavity 5, the transparent part extends along the length direction of the storage cavity 5, and a scale ruler 6 is arranged on the transparent part to facilitate observing the storage amount of the ointment in the storage cavity 5 and the extrusion amount of the ointment, so as to facilitate accurately controlling the extrusion amount of the ointment by controlling the extrusion mechanism. Further, an application nozzle 9 is further arranged on the extrusion head 8. A ointment outlet is arranged on the application nozzle 9 for extruding the ointment, and the application nozzle 9 can apply the ointment, which is convenient for evenly applying the ointment.

[0029] In this embodiment, the extrusion mechanism includes a threaded piston rod 2, a nut 3, and a piston 4. The nut 3 is fixed to the inner wall of the extrusion cylinder. The threaded piston rod 2 is threadedly connected to the nut 3. The piston 4 is disposed on one side of the threaded piston rod 2 close to the storage cavity 5. By rotating the threaded piston rod 2, it can move axially along the extrusion cylinder, thereby driving the piston 4 to move axially along the extrusion cylinder and pushing the ointment out.

[0030] Further, a handwheel 1 is also provided at one end of the threaded piston rod 2 away from the piston 4. The threaded piston rod 2 can be driven to rotate through the handwheel 1; alternatively, a driving device such as a motor or a motor can also be provided at one end of the threaded piston rod 2 away from the piston 4, and the threaded piston rod 2 can be driven to rotate through the driving device.

[0031] In this embodiment, the handwheel 1 is also connected to the extrusion cylinder through a one-way ratchet assembly, so that the handwheel 1 can only drive the threaded piston rod 2 to rotate unidirectionally. Specifically, the handwheel 1 can only drive the threaded piston rod 2 to rotate clockwise. When the threaded piston rod 2 rotates clockwise, it can push the piston 4 towards the extrusion head to extrude the ointment.

[0032] In this embodiment, the one-way ratchet assembly mainly includes a one-way ratchet and a pawl. The handwheel 1 is rotatably connected to the extrusion cylinder, and the one-way ratchet is connected to the handwheel 1. The pawl is disposed on the extrusion cylinder. The handwheel 1 can only rotate clockwise unidirectionally. When the handwheel 1 rotates counterclockwise, the pawl is engaged into the teeth of the one-way ratchet to limit its rotation.

[0033] In this embodiment, the diameter of the piston 4 matches the inner diameter of the extrusion cylinder (i.e., the diameter of the storage cavity 5), and a sealing ring is embedded on the side wall of the piston 4 to achieve sealing with the extrusion cylinder, facilitating the pushing of the ointment.

[0034] In this embodiment, a one-way valve 7 is also provided on the extrusion head 8. The one-way valve 7 enables the ointment to be extruded only unidirectionally, preventing the ointment that has been extruded onto the application nozzle 9 from flowing back into the storage cavity 5, playing an isolation role and preventing the mixing and contamination of the ointments.

[0035] In this embodiment, a flat portion is also provided at one end of the application nozzle 9 away from the extrusion head 8. The flat portion is made of a flexible material such as silicone. The ointment can be evenly applied through the flat portion, and the ointment outlet is provided at one end of the flat portion away from the extrusion head 8.

[0036] In this embodiment, the extrusion cylinder body is made of a transparent material such as transparent plastic or glass to form the transparent part, which facilitates observing the storage amount of the ointment. Moreover, a plurality of the scale rulers 6 are uniformly arranged on the extrusion cylinder body along its circumferential direction, so that the extrusion amount of the ointment can be observed at different angles. As a preferred implementation manner, the scale rulers 6 are arranged on both sides of the extrusion cylinder body, and the scale rulers 6 on both sides are arranged opposite to each other.

[0037] Alternatively, other transparent parts can also be selected according to needs. For example, a long strip-shaped observation window made of a transparent material can be arranged on the extrusion cylinder body along its length direction as the transparent part, and a plurality of the transparent parts can be evenly distributed along the circumferential direction of the extrusion cylinder body, which can more easily observe the storage amount and extrusion amount of the ointment in the storage cavity 5.

[0038] In this embodiment, the applicator further includes a sealing cover 10. When the applicator is not working, the sealing cover 10 can be buckled on the extrusion head 8 for protection.

[0039] In the present invention, specific examples are used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. At the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
