Description

Automatic accurate medicine discharging device

Technical Field

The invention relates to a medicine discharging device, in particular to an automatic accurate medicine discharging device.

Background

With the development of science and technology and the improvement of medical treatment level, the average life of old people is greatly improved, the aging degree of the population in China is more and more obvious, however, most of the old people have some chronic diseases and need to take medicines on time every day, and the medicines which need to be taken at different time are different, but as the old people age, the memory is reduced, the old people often forget to take medicines and forget to take medicines, so that the problem that the old people take medicines is always troubled for children. Although there are a lot of intelligent medicine boxes in the existing market, most of medicine boxes only remind the old man to eat the medicine, can accomplish to help the old man to prepare the medicine automatically seldom, and automatic medicine box of dispensing in the existing market is too expensive because the price, also is not suitable for most ordinary families to use, so to these problems, has designed an automatic accurate medicine device of simple structure relatively.

Disclosure of Invention

The invention aims to provide an automatic accurate medicine discharging device which can discharge a set amount of medicines in a set time, remind the old people of taking the medicines on time and achieve the purposes of dispensing medicines and reminding the old people of taking the medicines.

In order to achieve the purpose, the invention designs an automatic accurate medicine discharging device which comprises a box body, a front cover, a rear cover, an upper cover, a grooved wheel, a stepping motor, a stepped shaft, a battery box, a button battery, a brush, a groove type photoelectric sensor, a two-door transmission type photoelectric sensor, an lcd screen, a battery box cover, a funnel, a drawer, a control unit, a bearing, a spline and a key. The device is characterized in that a stepping motor is adopted to drive a sheave mechanism to rotate, a medicine storage bin is arranged above a sheave and directly pours medicine into the sheave, the medicine is directly contacted with the sheave, a groove corresponding to the size and shape of the medicine is formed in the sheave, the medicine directly contacts with the sheave, so when the sheave rotates, the medicine can fall into the groove, only one medicine can be placed in one groove, a brush is also arranged on the sheave and can block redundant medicine without damaging the medicine, in order to increase the probability that the medicine falls into the groove, the shape of the groove is the same as the shape of the medicine, the size of the groove is larger than that of one medicine, but two medicines cannot be placed, the medicine falling into the groove rotates along with the sheave, when the medicine falls from the groove to a certain degree, a funnel is arranged below, a groove-type photoelectric sensor is arranged at the outlet of the funnel, and the falling medicine can directly pass through a detection port of the sensor along the funnel, therefore, accurate counting is realized, in order to improve the counting precision and prevent the phenomenon that the hopper is blocked due to excessive medicines, the grooved wheel rotates by a certain angle at every time by utilizing a program and is stopped, and the grooved wheel rotates slowly as much as possible, so that the medicine box dispensing accuracy is greatly improved. In order to solve the problem that medicines with different models are difficult to distinguish and different families need to take medicines with different quantities, the modular structure is adopted, different modules are provided with grooved wheels with grooves with different sizes, and one grooved wheel can adapt to several medicines with slightly different sizes, so that each family can select the quantity and the type of the required modules according to the quantity and the model of the medicines taken by the old people at home, and unnecessary waste is avoided. The medicine box is provided with two indicating lamps, one red light and one green light, only when dispensing is correct, the green light is on, if dispensing is more, the red light can be on, after the old man sees, the old man can pour the medicine back to the medicine storage bin, presses the temporary dispensing button on the medicine box, and the medicine box can dispense medicine again, so that the accuracy of taking medicine by the old man at every time is ensured. A two-door transmission type photoelectric sensor is arranged behind the drawer and used for detecting whether the old people take medicines or not, and when the drawer is taken out, the sensor cannot detect things, and the buzzer stops giving an alarm. The modular design is adopted, one device represents one module, different grooved wheels are arranged on different modules, different medicines are dispensed, the different modules are matched at will, and multiple dispensing functions are achieved.

The invention has the beneficial effects that: the grooved wheel, the brush, the groove-shaped photoelectric sensor, the funnel and the stepping motor are matched to realize the accurate medicine discharging function; through adopting the modularized design, the modules provided with different grooved wheels are mutually matched, so that the distribution of different types of medicines is realized, and the requirements of different families are met. The device has the advantages of relatively simple structure, relatively low manufacturing cost, smaller volume and space saving, and is more suitable for common families.

Detailed Description

The invention is further explained below with reference to the figures and examples.

Referring to fig. 1, 2 and 3, the present invention includes a drawer 1, a groove type photoelectric sensor 2, a funnel 3, a grooved wheel 4, a brush 5, a key 6, a stepped shaft 7, a bearing 8, a box 9, a two-door transmission type photoelectric sensor 10, a control unit 11, a stepping motor 12, a battery box 13, a battery box cover 14, a diode 15, an lcd screen 16, a key 17, a rear cover 18, an upper cover 19, and a front cover 20. The stepping motor 12 directly contacts with the stepped shaft 7 to drive the stepped shaft 7 and the grooved pulley 4 to rotate, the brush 5 can block redundant medicine, and the medicine falling into the groove falls into the funnel 3 and falls into the drawer 1 along the outlet through the groove-shaped photoelectric sensor 2. The two-door transmission type photoelectric sensor 10 can detect whether the drawer 1 is taken out or not and control the buzzer to be closed. One module is provided with a grooved wheel 4, and different modules can be spliced together through connecting structures on two sides, so that the modules suitable for different types of medicines can be combined at will, and the requirements of different families can be met. Aiming at the medicine with smaller size, the grooved wheel is provided with two rows of grooves, and all the grooves are arranged at equal intervals, so that the positions of the grooves are distributed, the probability of the medicine falling into the grooves is increased, the medicine can fall sequentially, and the dispensing precision is improved. The rotation of the stepping motor 12 is controlled by the single chip microcomputer, so that the stepping motor stops for a certain time when rotating for a certain angle, and by adopting the mode, the phenomena that the medicine drops too fast, the outlet of the funnel 3 is blocked and the medicine is discharged and made mistakes can be effectively reduced. Two diodes 15 are used for showing whether the medicine is correct, and the correct green light that goes out the medicine is bright, and it is bright to go out the red light more of medicine, ensures the exactness that the old man took medicine, if go out the medicine and make mistakes, the old man falls the medicine back to the storage bin, presses interim medicine key, goes out the medicine again. The modular design is adopted, one device represents one module, different grooved wheels are arranged on different modules, different medicines are dispensed, the different modules are matched at will, and multiple dispensing functions are achieved.

The embodiment is only an illustration of the concept and implementation of the present invention, and is not a limitation, and technical solutions without substantial changes are still within the protection scope under the inventive concept.
