[0022] Embodiment 1: The present embodiment provides a medicament intelligent spraying system, comprising a bearing structure for accommodating functions, a medicament storage structure for storing medicaments, a control and monitoring structure for control and monitoring, an induction trigger structure for induction trigger, and a spraying structure for spraying medicaments.

[0023] The medicament storage structure is in communication with the spraying structure, so that the medicaments in the medicament storage structure can smoothly enter the spraying structure to provide a basis for subsequent spraying.

[0024] The control and monitoring structure is electrically connected with the induction trigger structure and the medicament storage structure, so that the control and monitoring structure can receive the signal of the induction trigger structure and control the medicament storage structure at the same time.

[0025] The induction trigger structure is arranged in cooperation with the medicament storage structure to sense the action of the medicament storage structure and transmit a signal to the control and monitoring structure, so that the control and monitoring structure can timely know the state of the medicament storage structure; the control and monitoring structure controls and monitors the spraying of the medicaments according to the signal, so as to realize precise spraying management of the medicaments; the spraying structure is used for spraying the medicaments in the medicament storage structure outward to complete the delivery of the medicaments. Through the synergistic effect of each structure, intelligent control and monitoring of medicament spraying are realized, and the convenience and accuracy of medicament use are improved.

[0026] In the embodiment, further, the induction trigger structure comprises an induction component for inducing the action of the medicament storage structure and a trigger component for cooperating with the induction component, the trigger component is arranged on the medicament storage structure and moves with the medicament storage structure; the induction component is arranged on the control and monitoring structure and is in a fixed position to receive the signal of the trigger component. When the trigger component moves with the medicament storage structure, the relative position or the magnetic field state of the induction component changes, the induction component senses the change and transmits a signal to the control and monitoring structure, thereby realizing the monitoring of the action state of the medicament storage structure, providing a basis for subsequent control and monitoring, and ensuring the timeliness and accuracy of the action monitoring of the medicament storage structure.

[0027] In the embodiment, further, the trigger component is two magnets arranged axially adjacent to each other and having opposite polarities, so that the magnetic field change of the two magnets is more obvious when the medicament storage structure moves; the induction component is an induction switch adapted to the two magnets, which can accurately induce the magnetic field change of the two magnets. When the medicament storage structure moves, the relative position of the two magnets changes synchronously with the medicament storage structure, so that the induction switch senses the magnetic field change and generates a corresponding signal. The induction switch can only induce a magnet with one polarity, and the two magnets have a boundary line. When the boundary line passes through the induction area of the induction switch, the next magnet induces the induction switch, and the induction switch makes a logical count. Compared with the prior art which uses only one two-polarity counting magnet, this arrangement makes the induction of the induction switch and the trigger component more sensitive, can more accurately induce the action of the medicine bottle 2, and improves the accuracy of the induction of the action of the medicament storage structure, thereby laying a foundation for the subsequent accurate control of the medicament spraying.

[0028] In this embodiment, further comprising a magnetic control switch structure for controlling the on-off of the circuit, the magnetic control switch structure comprises a first magnet, a second magnet and a magnetic sensitive element, the first magnet is connected with the cover 6 for covering the spraying structure and moves with the opening and closing of the cover 6; the second magnet is arranged on the bearing structure and is fixed in position; the magnetic sensitive element is electrically connected with the control monitoring structure and serves as a key element of the circuit on-off. When the cover 6 covers the spraying structure, the relative position of the first magnet and the second magnet makes them form an interference magnetic circuit which acts on the magnetic sensitive element, so that the same-pole repulsion force is generated in the internal pin of the magnetic sensitive element, thereby breaking the circuit in which the magnetic sensitive element is located, at this time the system is in a non-working state, unnecessary power consumption and misoperation are avoided; when the cover 6 is opened, the first magnet moves with the cover 6, the magnetic circuit of the first magnet and the second magnet changes, this change makes the internal pin of the magnetic sensitive element be attracted under the action of the magnetic force, thereby connecting the circuit in which the magnetic sensitive element is located, at this time the system switches to the working state, the intelligent switching of the system working state is realized, manual operation of the complex mechanical switch is not needed, the convenience and intelligent degree of use are improved.

[0029] In this embodiment, further, the control monitoring structure can display the dose or the change of the remaining amount of the medicament in the medicament storage structure in real time according to the signal of the induction trigger structure, so that the user can clearly know the use of the medicament and avoid overuse or insufficient use; and the medicament spraying action is automatically stopped after the single use process is completed, so as to prevent repeated spraying of the medicament; and an alarm prompt is issued to timely inform the user that the use is completed, so as to realize the intelligent monitoring and prompting of the use process, and improve the safety and convenience of the use of the medicament.

[0030] The embodiment 2 is a medicine intelligent sprayer which is made by using the medicine intelligent spraying system. The medicine intelligent sprayer comprises a shell 1, a medicine bottle 2, a circuit board 3, a reed tube 4, a panel 5, a cover 6, a first magnet 7, a nozzle 8, a display screen 9, a switch 10, a second magnet 11, a single-pole Hall switch 12 and a spray pipe 13. The shell 1 is internally formed with a cavity to provide accommodation space for the internal structures. The cavity is communicated with the nozzle 8 to ensure that the medicine can be sprayed out of the cavity through the nozzle 8. The medicine bottle 2 and the circuit board 3 are fixed side by side and adjacent to each other in the cavity of the shell 1. The two are close to each other in position to facilitate electrical connection and signal transmission. The reed tube 4 is fixed on the surface of the circuit board 3 and serves as a magnetic sensitive element to participate in the circuit on-off control. The panel 5 is covered on one side of the shell 1 and corresponds to the position of the circuit board 3 to play a protective and cooperative role. The nozzle 8 is integrally formed on the end of the shell 1 and is the outlet for spraying the medicine. The cover 6 is hingedly covered on the nozzle 8 to control the opening and closing of the nozzle 8. The first magnet 7 is fixed on the side of the cover 6 facing the nozzle 8 and moves with the cover 6. The second magnet 11 is fixed on the outer surface of the medicine bottle 2 close to the pressing end and moves with the medicine bottle 2. The second magnet 11 is two magnets with opposite polarities and arranged adjacent to each other along the axis of the medicine bottle 2 to enhance the inductive effect of the magnetic field change. The single-pole Hall switch 12 is fixed on the circuit board 3 and corresponds to the position of the second magnet 11 to form an inductive adaptation and accurately induce the magnetic field change of the second magnet 11. There is a boundary line between the two second magnets 11, and the single-pole Hall switch 12 can only induce one of the second magnets 11. After the medicine bottle 2 is pressed, the second magnet 11 is induced by the single-pole Hall switch 12 after the boundary line enters the induction area of the single-pole Hall switch 12, and a counting logic is generated. The spray pipe 13 is integrally formed on the bottom of the cavity of the shell 1. One end of the spray pipe 13 corresponds to the nozzle 8 and is communicated with the nozzle 8 to ensure that the medicine can flow from the spray pipe 13 to the nozzle 8. The other end of the spray pipe 13 is inserted and adapted with one end of the medicine bottle 2 to enable the medicine in the medicine bottle 2 to enter the spray pipe 13. The display screen 9 and the switch 10 are respectively fixed on the side of the circuit board 3 facing the panel 5. The display screen 9 is used to display the medicine information, and the switch 10 is used for operation control. The panel 5 is provided with a third magnet corresponding to the position of the first magnet 7. The third magnet can form an interference magnetic circuit with the first magnet 7 to participate in the circuit on-off control. The connection relationship between the components is clear, the position cooperation is accurate, the stable operation of the sprayer is ensured, and the reliability of the overall structure is improved.

[0031] In this embodiment, further, when the cover 6 is closed on the nozzle 8, the relative position of the first magnet 7 on the cover 6 and the third magnet on the panel 5 makes them form a closed interference magnetic circuit, which acts on the reed switch 4 to generate a same-pole repulsion force between the two pins inside the reed switch 4, thereby breaking the circuit in which the reed switch 4 is located, at which time the medicine sprayer is in a non-working state, avoiding accidental spraying of the medicine; when the cover 6 is moved away from the nozzle 8, the first magnet 7 moves synchronously with the cover 6, the relative position of the first magnet 7 and the third magnet changes, and the interference magnetic circuit formed by the first magnet 7 and the third magnet disappears, and the magnetic circuit of the third magnet alone acts on the reed switch 4, causing the two pins inside the reed switch 4 to be attracted under the action of the magnetic force, thereby connecting the circuit in which the reed switch 4 is located, at which time the medicine sprayer switches to a working state, realizing automatic switching of the working state of the medicine sprayer and improving the convenience of use.

[0032] In this embodiment, further, when the pressing end of the medicine bottle 2 is pressed, the medicine bottle 2 moves downward in the axial direction under the pressure, and the movement of the medicine bottle 2 drives the two second magnets 11 fixed on the medicine bottle 2 to move synchronously, the movement of the two second magnets 11 makes the polarity boundary line between the two second magnets 11 pass through the sensing area of the single-pole Hall switch 12, and the single-pole Hall switch 12 generates an electrical signal after sensing the change in the magnetic field and transmits it to the circuit board 3, which processes the signal after receiving it and then controls the display screen 9 to display the real-time dose or the percentage change in the remaining amount of the medicine in the medicine bottle 2, allowing the user to have real-time knowledge of the medicine; at the same time, the medicine in the medicine bottle 2 is sprayed out of the nozzle 8 through the spray pipe 13 under the action of the pressure generated by the pressing, completing the spraying of the medicine. This process realizes the synchronization of medicine spraying and dose display, improving the accuracy and visibility of medicine use.

[0033] In this embodiment, further, the single-pole Hall switch 12 only has sensing ability for magnets of a specific polarity, and can accurately generate a sensing signal when the part of the second magnet 11 with the specific polarity passes through the sensing area of the single-pole Hall switch 12; while the part of the second magnet 11 with another polarity passes through, the single-pole Hall switch 12 does not generate a sensing signal. This feature enables the single-pole Hall switch 12 to accurately identify the movement of the second magnet 11, thereby accurately identifying the movement stroke of the medicine bottle 2 and providing an accurate basis for subsequent accurate control of medicine spraying.

[0034] Further, when the single-dose process is completed, i.e. the pressing action of the medicine bottle 2 is ended and reset, the circuit board 3 judges that the medicine has been used according to the signal transmitted by the single-pole Hall switch 12, and then automatically controls the relevant components to stop the medicine spraying action, preventing the medicine from continuing to spray and causing waste or overuse of medicine; at the same time, the alarm device on the circuit board 3 emits a beeping sound alarm to timely prompt the user that the single-dose use has been completed, avoiding repeated use of medicine, and improving the safety and standardization of medicine use.

[0035] In addition, the dry reed 4 can also be provided in the form of being provided with a magnet on the end face, and a magnetic circuit loop is formed between the first magnet 7 and the magnet, so as to reduce the suction force of the two poles inside the dry reed 4, so that the pins of the dry reed 4 repel each other, and the same function is realized.

[0036] The medicine sprayer, as a specific carrier of the system, first realizes the working state switching through the magnetic control on-off structure. When the cover 6 covers the nozzle 8, the first magnet 7 on the cover 6 and the third magnet on the panel 5 form an interference magnetic circuit, so that the pins of the dry reed 4 on the circuit board 3 repel and break the circuit, and the medicine sprayer is in a non-working state. When the cover 6 is turned away, the interference magnetic circuit disappears, the pins of the dry reed 4 attract and connect the circuit, and the circuit board 3 enters a standby working state. Then, when the user presses the pressing end of the medicine bottle 2, the medicine bottle 2 moves axially and synchronously moves the two second magnets 11 with opposite polarities on it, so that the polarity boundary line between the two magnets passes through the sensing area of the single-pole Hall switch 12 on the circuit board 3. After the single-pole Hall switch 12 (only sensing a specific polarity) senses the change of the magnetic field, an electric signal is generated and transmitted to the circuit board 3. After receiving the signal, the circuit board 3 controls the display screen 9 to display the real-time dose or the percentage of the remaining medicine in the medicine bottle 2, and on the other hand, the medicine in the medicine bottle 2 is sprayed from the nozzle 8 through the spray pipe 13 under the action of the pressing force. When the single-dose use is completed and the medicine bottle 2 is reset, the polarity boundary line of the second magnet 11 leaves the sensing area, the single-pole Hall switch 12 stops signaling, the circuit board 3 judges that the medicine has been used, and automatically stops the medicine spraying and controls the alarm device to emit a beeping sound to prompt. The whole process realizes the intelligent operation of the whole process from state recognition to precise spraying, monitoring and prompting.

[0037] The embodiments of the present application are described above in combination with the drawings, and the embodiments and features in the embodiments of the present application can be combined with each other without conflict, and the present application is not limited to the above specific embodiments. The above specific embodiments are only illustrative, not limiting, and those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope protected by the claims.

The display screen and the switch are respectively fixed on the side of the circuit board facing the panel. The panel is provided with a third magnet corresponding to the position of the first magnet. The third magnet can form an interfering magnetic circuit with the first magnet.

7. The intelligent pesticide sprayer according to claim 6, characterized in that, When the cover is closed on the nozzle, the first magnet on the cover and the third magnet on the panel form a closed interference magnetic circuit. This magnetic circuit acts on the reed switch, causing the two pins inside the reed switch to repel each other, thereby disconnecting the circuit where the reed switch is located. At this time, the sprayer is in a non-working state. When the cover is opened from the nozzle, the first magnet moves synchronously with the cover, causing the interference magnetic circuit formed by the first magnet and the third magnet to disappear. The magnetic circuit of the third magnet acts solely on the reed switch, causing the two pins inside the reed switch to attract under the action of magnetic force, thereby connecting the circuit where the reed switch is located. At this time, the sprayer switches to the working state.

8. The intelligent pesticide sprayer according to claim 6, characterized in that, When the pressing end of the medicine bottle is pressed, the medicine bottle moves downward along the axis, causing the two second magnets fixed on the medicine bottle to move synchronously. This causes the polarity boundary line between the two second magnets to pass through the sensing area of ​​the unipolar Hall switch. After sensing the change in the magnetic field, the unipolar Hall switch generates an electrical signal and transmits it to the circuit board. After receiving the signal, the circuit board controls the display screen to show the real-time dosage or remaining percentage of the medicine in the medicine bottle. At the same time, the medicine in the medicine bottle is sprayed out from the nozzle through the spray pipe under pressure.

9. The intelligent pesticide sprayer according to claim 6, characterized in that, The unipolar Hall switch only senses magnets of a specific polarity. When the portion of the second magnet with that specific polarity passes through the sensing area of ​​the unipolar Hall switch, the unipolar Hall switch generates a sensing signal. When the portion of the second magnet with the other polarity passes through, the unipolar Hall switch does not generate a sensing signal, thereby achieving accurate identification of the movement of the medicine bottle.

10. The intelligent pesticide sprayer according to claim 6, characterized in that, Once a single medication administration is completed, i.e., the pressing action on the medicine bottle ends and it resets, the circuit board determines that the medication administration is complete based on the signal transmitted by the single-pole Hall switch, automatically stops the medication spraying action, and simultaneously controls the alarm device on the circuit board to emit a buzzer alarm.
