Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1 to 5, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

Referring to fig. 1, the applicator device of this embodiment comprises a loading container 1, an applicator pad 2, and a squeezer 3. The loading container 1 is used for loading ointment, and the squeezer 3 is used for squeezing the ointment in the loading container 1 to the applicator pad 2, and the applicator pad 2 is used for contacting with the skin to apply the ointment.

In detail, as shown in fig. 2 to 5, the loading container 1 has a liquid storage space 11, a front liquid outlet 12 at the front end of the liquid storage space 11, and a rear opening 13 at the rear end of the liquid storage space 11; the applicator pad 2 is obliquely connected and fixed with the front end of the loading container 1, and the applicator pad 2 is communicated with the front liquid outlet 12 to allow the ointment in the liquid storage space 11 to flow to the applicator pad 2; the squeezer 3 is connected with the tail end of the loading container 1, the squeezer 3 comprises a shell 31 fixedly connected with the tail end of the loading container 1, the housing 31 has a receiving cavity communicating with the open rear opening 13, a screw 32 is provided in the receiving cavity, the screw 32 has a first thread on the periphery, the front end of the screw 32 extends to the liquid storage space 11 and is connected with a piston part 33, the piston part 33 is located in the liquid storage space 11 and is connected with the side wall of the liquid storage space 11 in a sealing and sliding way, a rotating shell 34 capable of rotating in the same plane is sleeved on the outer side of the shell 31, a connection portion 341 is formed inside the rotary shell 34, the connection portion 341 has a socket hole 342 coaxially disposed with the rotary shell 34, the socket hole 342 is provided with an internal thread, and the internal thread of the socket hole 342 is connected with the first thread of the screw rod 32 to drive the screw rod 32 to move in the axial direction when the rotary shell 34 is rotated.

When the medical ointment extruding device is used, the loading container 1 and/or the shell 31 are held, then the rotating shell 34 is rotated by fingers to control the rotation of the screw rod 32, the screw rod 32 can move along the axial direction while rotating, ointment can be extruded in the moving process, the medical ointment extruding device is very convenient to use, the stroke control is realized by adopting the threaded connection of the screw rod 32 and the rotating shell 34, the rotating shell 34 rotates for one circle to correspond to the axial displacement of the screw rod 32 to be one thread pitch in the actual control process, and therefore the control precision can be improved, and the extruding amount can be conveniently controlled.

In detail, in this embodiment, the loading container 1 has a cylindrical structure, and the liquid storage space 11 also has a cylindrical structure. The reservoir 11 can be sized as needed to accommodate loading of different amounts of ointment for a particular application.

In order to realize the rotation of the rotating shell 34 in the same plane, an inward-recessed limiting ring groove 311 is formed in the outer side of the tail end of the outer shell 31, and a groove 312 formed in the axial direction is formed in the part, where the limiting ring groove 311 is located, of the outer shell 31; the inner side of the rotating case 34 has an annular protrusion 343, and the annular protrusion 343 is engaged with the stopper ring groove 311 and is rotatable in the same plane along the stopper ring groove 311. Specifically, during assembly, the rotating shell 34 is pressed in from the tail end of the outer shell 31 to the direction of the limiting ring groove 311, because the inner diameter of the annular protrusion 343 is smaller than the size of the tail end of the outer shell 31, the tail end of the outer shell 31 is elastically deformed during pressing in until the tail end of the outer shell 31 recovers after the annular protrusion 343 is inserted into the limiting ring groove 311, at this time, the rotating shell 34 is rotatably assembled at the tail part of the outer shell 31, so that when the rotating shell 34 is rotated, the rotating shell 34 rotates around the limiting ring groove 311 in the same surface, and the rotating shell 34 cannot be separated from the tail part of the outer shell 31 during rotation.

Specifically, the connection portion 341 is fixed on the inner side of the rotary shell 34, when the rotary shell 34 rotates, the connection portion 341 rotates, the sleeve hole 342 of the connection portion 341 is connected with the first thread of the screw rod 32, when the rotary shell 34 rotates, the screw rod 32 rotates, and meanwhile, the screw rod 32 also moves in the axial direction, so that the ointment can be extruded in the moving process. In a specific application, the first thread is a thread with a square cross section. In order to prevent the slip, it is convenient to rotate the rotating shell 34, and the outer side of the rotating shell 34 has a convex line, thereby increasing the friction force.

In order to ensure the stability of the screw rod 32 during sliding and rotating, a sliding ring 321 is provided on the outer side of the screw rod 32 to engage with the inner wall of the housing 31. When the screw 32 rotates and slides, the slip ring 321 contacts the inner wall of the housing 31, which ensures that no oscillation occurs in the radial direction.

Further, the tail end of the rotating shell 34 is also matched with a top cover 4, and the rotating shell 34 is positioned between the top cover 4 and the shell 31; the top cover 4 has a receiving space for enclosing a screw 32 rotated to the outside of the housing 31. When the loading container 1 is filled with ointment, a large portion of the screw 32 is located outside the housing 31, and this portion of the screw 32 will be housed inside the cap 4, which does not affect the appearance of the entire applicator and protects the screw 32.

In detail, in this embodiment, the top cover 4 is connected to the housing 31 in a snap-fit manner, which is beneficial to facilitating the assembly and disassembly.

In some embodiments, the loading container 1 has a cylindrical shape, and for easy handling, finger-like grips are provided around the periphery of the loading container 1. The applicator can be held by holding the hand on the finger-like gripping portion while holding the applicator.

In a word, the technical scheme of the utility model is holding the back of medicator and rotating rotatory shell 34 with the finger and can realizing extruding of ointment, can conveniently grip like this and extrude the ointment.

Variations and modifications to the above-described embodiments may occur to those skilled in the art, in light of the above teachings and teachings. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
