DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 and Figure 4, the present utility model provides a technical solution: an automatic metering device suitable for small-area application, including a storage cylinder 1, a cylinder cover 2 is arranged at the upper end of the storage cylinder 1. The setting of the cylinder cover 2 can close the storage cavity 8 in the storage cylinder 1, avoiding the internal liquid medicine from being contaminated and facilitating the cleaning of the storage cavity 8. A thumb ring 3 is arranged on one side of the storage cylinder 1. Through the setting of the thumb ring 3, it is more convenient for the user to pick up the storage cylinder 1 for applying medicine. A metering cylinder 4 is fixedly connected to the lower end of the storage cylinder 1, a connecting block 5 is fixedly connected to the lower end of the metering cylinder 4, and a discharging mechanism 6 is fixedly connected to the lower end of the connecting block 5. A metering mechanism 7 is embedded in the bottom wall of the inner cavity of the storage cylinder 1, a storage cavity 8 is embedded in the inner wall of the storage cylinder 1, a metering cavity 9 is embedded in the inner wall of the metering cylinder 4, and a discharging port 10 is opened on the bottom wall of the storage cylinder 1. The discharging mechanism 6 includes a liquid down pipe 61, the upper end of the liquid down pipe 61 is fixedly connected to the lower end of the connecting block 5, a liquid inlet groove 62 is arranged on the inner wall of the liquid down pipe 61, a liquid storage groove 63 is arranged in the middle of the liquid down pipe 61, a sliding rod 64 is inserted in the middle of the liquid storage groove 63, and a spring 65 is sleeved on the outer wall of the sliding rod 64. Under the elastic action of the arranged spring 65, it is convenient to reset the sliding rod 64 and the plug 66, and the opening on the top wall of the ball groove 67 can be sealed. A plug 66 is fixedly connected to the lower end of the sliding rod 64, a ball groove 67 is opened at the lower end of the liquid down pipe 61, and a massage ball 68 is embedded in the inner wall of the ball groove 67. Since the outer diameter of the massage ball 68 is smaller than the inner diameter of the ball groove 67, the liquid medicine can flow out through the gap between the ball groove 67 and the massage ball 68 and contact the skin. And multiple massage balls 68 can be set in different diameters, so as to control the flow rate of different flows. The outer wall of the cylinder cover 2 is threadedly connected to the top of the inner wall of the storage cylinder 1, and one side of the thumb ring 3 is fixedly connected to one side of the storage cylinder 1.

[0024] Please refer to Figure 2 , in order to quickly discharge and apply the liquid medicine in the metering cavity 9, the inner wall of the liquid down pipe 61 is embedded with the outer wall of the liquid inlet groove 62, the outer wall of the liquid storage groove 63 is embedded with the inner wall of the liquid down pipe 61, and a sealing gasket is wrapped on the outer side wall surfaces of the sliding rod 64 and the plug 66. The sealing gasket enhances the sealing performance and prevents the liquid medicine from leaking out.

[0025] Please refer to Figure 3, in order to quickly open and close the discharge port 10, the metering mechanism 7 includes a transverse groove 71. The outer wall of the transverse groove 71 is inlaid and connected with the inner wall bottom of the storage cylinder 1. A switching plate 72 is arranged on the inner wall of the transverse groove 71. A transverse groove 71 is opened at the discharge port 10 on the lower side of the storage cylinder 1. The switching plate 72 is slidably sealed in the transverse groove 71 and its length is half of that of the transverse groove 71. A communication port 75 matching the discharge port 10 is opened at the upper side part of the switching plate 72. Two pull rods 73 are symmetrically slidably arranged in the storage cylinder 1 and extend into the transverse groove 71 to be connected with the switching plate 72. A pull rod 73 is arranged on one side of the switching plate 72. A pull plate 74 is fixedly connected to the side of the pull rod 73 away from the switching plate 72. A communication port 75 is penetrated and opened on one side of the switching plate 72. The inner wall of the transverse groove 71 is slidably connected with the outer wall of the switching plate 72. One side of the switching plate 72 is fixedly connected with one side of the pull rod 73. The same pull rods 73 and pull plates 74 are opened on both sides of the switching plate 72, and the pull rod 73 and the pull plate 74 are of an integral structure.

[0026] Working principle: First, the user preloads the liquid medicine to be applied into the storage cylinder 1, and then pulls the pull plate 74 to move to one side. The two pull rods 73 on both sides are red and green respectively. When the red pull rod 73 is attached to the storage cylinder 1, it is in the open state, that is, the red pull rod 73 pushes the switching plate 72 to move in the transverse groove 71, so that the communication port 75 of the switching plate 72 corresponds to the discharge port 10 of the storage cylinder 1, enabling the liquid medicine in the storage cylinder 1 to flow into the metering cavity 9 in the metering cylinder 4;

[0027] Then, when the communication port 75 of the on-off plate 72 corresponds to the discharge port 10 of the storage cylinder 1, when pharmaceutical application is required, the upper end of the sliding rod 64 is located between the liquid inlet groove 62 and the liquid storage groove 63. When not in use, the sliding rod 64 fits against the bottom wall of the liquid inlet groove 62. Then, the massage ball 68 is forced to be squeezed upward, pushing up the plug 66, creating a gap between the plug 66 and the ball groove 67. The liquid medicine can flow into the ball groove 67 and flow onto the skin surface along the surface of the rolling massage ball 68. Since the capacity of the metering chamber 9 is fixed, the quantitative outflow of the liquid medicine is achieved, and it is more convenient and effective to cover the massage ball 68 with the liquid medicine. When the liquid medicine gradually covers the massage ball 68, the position where the user needs to apply the medicine can be selected, and then the massage ball 68 is repeatedly rolled and pressed for application. In this way, the rolling of the massage ball 68 can more effectively apply the liquid medicine, improving the uniformity and coverage. When only the liquid medicine needs to be applied, first, the liquid medicine in the storage chamber 8 flows into the metering chamber 9, and then the pull rod 73 is pulled to close the discharge port 10 with the on-off plate 72, which can prevent the liquid medicine in the storage cylinder 1 from being automatically extruded. This makes the application of the liquid medicine more convenient and fast. Further, in the non-use state, under the action of the self-weight of the sliding rod 64 and the spring 65, the sliding rod 64 drives the plug 66 to move downward, and the plug 66 blocks the opening at the top wall of the ball groove 67. At this time, the cylinder cover 2 can be opened to add liquid medicine inside. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
