Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medicine sprayers, and particularly relates to a medicine intelligent spraying system and a medicine intelligent sprayer. BACKGROUND

[0002] In the medical field, a medicine inhaler is a key medical device for helping patients with respiratory system diseases such as asthma and chronic obstructive pulmonary disease to accurately inhale treatment medicine into the body. The traditional medicine inhaler has obvious technical defects: on the one hand, the sensing trigger structure thereof is mostly composed of a single piece of double-face polarity magnet matched with a sensing element, the change amplitude of the magnetic field generated when the single piece of magnet moves is small, the recognition sensitivity of the sensing element to the pressing action of the medicine bottle (medicine storage structure) is low, the moving stroke of the medicine bottle cannot be accurately captured, and thus the single medicine spraying dose cannot be accurately judged, and the patient is prone to the problems of overuse (causing side effects) or insufficient use (affecting the treatment effect) of the medicine due to inaccurate dose control; on the other hand, the traditional inhaler does not clearly define the specific installation positions of the sensing component and the trigger component, the magnetic field sensing adaptation mode, and the like, so that the system cannot stably realize the complete logic of "medicine bottle action sensing-signal transmission to the control structure-accurate control of spraying", and the intelligent degree is low, and it is difficult to meet the clinical use requirements for the accuracy and reliability of medicine inhalation. SUMMARY

[0003] The purpose of the present application is to provide a medicine intelligent spraying system and a medicine intelligent sprayer to solve the problems in the background art.

[0004] Therefore, the present application provides a medicine intelligent spraying system and a medicine intelligent sprayer, which comprises a bearing structure for accommodating function, a medicine storage structure for storing medicine, a control and monitoring structure for control and monitoring, a sensing trigger structure for sensing trigger, and a spraying structure for spraying medicine. The medicine storage structure is in communication with the spraying structure, the control and monitoring structure is electrically connected with the sensing trigger structure and the medicine storage structure, the sensing trigger structure comprises a sensing component and two trigger magnets with opposite polarity arranged axially adjacent to the medicine storage structure, the sensing component is an inductive switch adapted to the two trigger magnets, the sensing component is arranged on the control and monitoring structure, and the two trigger magnets are arranged on the medicine storage structure. The sensing trigger structure is arranged in cooperation with the medicine storage structure to sense the action of the medicine storage structure and transmit signals to the control and monitoring structure. The control and monitoring structure controls and monitors the spraying of medicine according to the signals, and the spraying structure is used for spraying the medicine in the medicine storage structure outward.

[0005] In a further embodiment of the present invention, the sensing component of the induction triggering structure is used to sense the action of the drug storage structure. The triggering component consists of two trigger magnets with opposite polarities that cooperate with the sensing component. The triggering component is fixedly disposed on the outer surface of the drug storage structure, and the sensing component is fixedly disposed at the corresponding position of the control and monitoring structure. When the triggering component moves axially with the drug storage structure, the relative positions of the two trigger magnets change synchronously, so that the sensing component senses the change in magnetic field and transmits a signal to the control and monitoring structure, thereby realizing the monitoring of the action status of the drug storage structure.

[0006] In a further embodiment of the present invention, the triggering component is two magnets that are adjacent to each other and closely arranged along the axial direction of the drug storage structure, and the two magnets have opposite polarities. The sensing component is an inductive switch adapted to the two magnets. The inductive switch can detect the change in magnetic field polarity generated when the two magnets move. When the drug storage structure moves along the axial direction, the two magnets move synchronously with the drug storage structure, so that the polarity boundary line between the two magnets passes through the sensing area of ​​the inductive switch. After sensing the change in magnetic field, the inductive switch generates a corresponding electrical signal and transmits it to the control and monitoring structure.

[0007] A further embodiment of the present invention includes a magnetically controlled switching structure for controlling the on / off state of the circuit. The magnetically controlled switching structure includes a first magnet, a second magnet, and a magnetically sensitive element. The first magnet is connected to a cover for closing the spraying structure, the second magnet is disposed on the supporting structure, and the magnetically sensitive element is electrically connected to the control and monitoring structure. When the cover closes the spraying structure, the first magnet and the second magnet form an interfering magnetic circuit, causing the like poles of the internal pins of the magnetically sensitive element to repel each other to disconnect the circuit. When the cover is opened, the change in the magnetic circuit of the first magnet and the second magnet causes the internal pins of the magnetically sensitive element to magnetically attract each other to connect the circuit, thereby realizing the switching of the system's operating state.

[0008] In a further embodiment of the present invention, the control and monitoring structure can display the changes in dosage or remaining amount of medicine in the medicine storage structure in real time according to the signal of the sensing and triggering structure, and automatically stop the medicine spraying action and issue an alarm prompt after a single medication process is completed, so as to realize intelligent monitoring and prompting of the medication process.

[0009] A smart pesticide sprayer, manufactured using a smart pesticide spraying system, includes a housing, a pesticide bottle, a circuit board, a reed switch, a panel, a cap, a first magnet, a nozzle, a display screen, a switch, a second magnet, a unipolar Hall effect switch, and a spray nozzle. The housing has an internal cavity connected to the nozzle. The pesticide bottle and the circuit board are fixed side-by-side and adjacent within the cavity of the housing. The reed switch is fixed to the surface of the circuit board. The panel covers one side of the housing and corresponds to the position of the circuit board. The nozzle is integrally formed at one end of the housing. The cap is closable and can be opened and closed over the nozzle. The first magnet is fixed to the... The cap faces the nozzle. The second magnet is fixed to the outer surface of the medicine bottle near the pressing end. The second magnet consists of two magnets with opposite polarities arranged adjacent to each other along the axial direction of the medicine bottle. The unipolar Hall switch is fixed on the circuit board and forms an inductive adaptation corresponding to the position of the second magnet. The nozzle is integrally formed in the bottom of the cavity of the outer shell, and one end of the nozzle is connected to the nozzle and the other end is inserted into one end of the medicine bottle. 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.

[0010] In a further embodiment of the present invention, 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 generate a repulsive force, 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.

[0011] In a further embodiment of the present invention, when the pressing end of the medicine bottle is pressed, the medicine bottle moves downward along the axial direction, causing the two second magnets fixed on the medicine bottle to move synchronously, so that the polarity boundary line between the two second magnets passes 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 display the real-time dosage or remaining percentage change 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.

[0012] In a further embodiment of the present invention, the unipolar Hall switch only generates a sensing capability for 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, so as to achieve accurate identification of the movement of the medicine bottle.

[0013] In a further embodiment of the present invention, when a single medication process is completed, that is, after the pressing action of the medicine bottle ends and it is reset, the circuit board determines that the medication is completed based on the signal transmitted by the single-pole Hall switch, automatically stops the medication spraying action, and at the same time controls the alarm device on the circuit board to emit a buzzer alarm.

[0014] The beneficial effects of this invention are:

[0015] Significantly improves the accuracy of medication dosage: The inductive triggering structure adopts a technical solution of "two trigger magnets with opposite polarities set adjacent to each other along the axis of the medicine bottle + an adapted inductive switch". When the two magnets with opposite polarities move, they generate a significant change in magnetic field, which enables the inductive switch to accurately identify the pressing stroke of the medicine bottle. This provides an accurate signal for the control and monitoring structure, effectively avoiding medication dosage deviations caused by insensitive sensing, ensuring clinical treatment effects and reducing the risk of side effects.

[0016] To ensure the reliability of inhaler operation: Clarify the specific cooperation relationship between the sensing component (sensor switch) located in the control and monitoring structure and the trigger magnet located in the medicine bottle, clearly define the collaborative logic of "medicine bottle motion sensing - signal transmission - control spraying", reduce operational failures caused by unclear structural cooperation, and ensure that the inhaler can stably achieve intelligent spraying and monitoring functions every time the patient uses it, thereby improving the reliability of medical use.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

They are only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a preset orientation or be constructed and operated in a preset orientation. Therefore, they should not be construed as limiting the scope of protection of this application. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0025] It should be noted that, in this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, it should be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.

[0026] Example 1: This example provides a smart pesticide spraying system, including a support structure for accommodating functions, a pesticide storage structure for storing pesticides, a control and monitoring structure for control and monitoring, a sensor triggering structure for induction triggering, and a spraying structure for spraying pesticides.

[0027] The agent storage structure is connected to the spraying structure, so that the agent in the agent storage structure can smoothly enter the spraying structure, providing a basis for subsequent spraying.

[0028] The control and monitoring structure is electrically connected to the induction trigger structure and the drug storage structure, so that the control and monitoring structure can receive signals from the induction trigger structure and control the drug storage structure at the same time.

[0029] The sensing trigger structure works in conjunction with the drug storage structure to sense the movement of the drug storage structure and transmit signals to the control and monitoring structure, allowing the control and monitoring structure to promptly know the status of the drug storage structure. The control and monitoring structure controls and monitors the drug spraying based on the signals, thereby achieving precise drug spraying management. The spraying structure is used to spray the drug from the drug storage structure outwards, completing the drug delivery. Through the synergistic effect of these structures, intelligent control and monitoring of drug spraying are achieved, improving the convenience and accuracy of drug use.

[0030] In this embodiment, the sensing triggering structure further includes a sensing component for sensing the movement of the drug storage structure and a triggering component for cooperating with the sensing component. The triggering component is disposed on the drug storage structure and moves together with it. The sensing component is disposed on the control and monitoring structure and is in a fixed position to receive signals from the triggering component. When the triggering component moves with the drug storage structure, it changes its relative position or magnetic field state with the sensing component. The sensing component senses this change and transmits a signal to the control and monitoring structure, thereby monitoring the movement state of the drug storage structure and providing a basis for subsequent control and monitoring, ensuring the timeliness and accuracy of monitoring the movement of the drug storage structure.

[0031] In this embodiment, the triggering component further comprises two magnets with opposite polarities arranged adjacent to each other along the axial direction of the drug storage structure. This makes the magnetic field change of the two magnets more pronounced when the drug storage structure is activated. The sensing component is an inductive switch adapted to the two magnets, capable of accurately sensing the magnetic field changes of the two magnets. When the drug storage structure is activated, the relative position of the two magnets changes synchronously with the drug storage structure, causing the inductive switch to sense the magnetic field change and generate a corresponding signal. The inductive switch can only sense a magnet of one polarity. There is a dividing line between the two magnets. When the dividing line passes through the sensing area of ​​the inductive switch, the next magnet senses the inductive switch, and the inductive switch performs a count. Compared to the prior art that uses only one bipolar counting magnet, this configuration makes the inductive switch and triggering component more sensitive and can more accurately sense the movement of the medicine bottle 2, improving the accuracy of sensing the movement of the drug storage structure and laying the foundation for subsequent precise control of drug spraying.

[0032] In this embodiment, a magnetic control switching structure for controlling the on / off state of the circuit is further included. The magnetic control switching structure includes a first magnet, a second magnet, and a magnetic sensitive element. The first magnet is connected to the cover 6 for closing the spraying structure and moves with the opening and closing of the cover 6. The second magnet is disposed on the bearing structure and is fixed in position. The magnetic sensitive element is electrically connected to the control and monitoring structure and serves as a key component for the on / off state of the circuit. When the cover 6 closes the spraying structure, the relative positions of the first magnet and the second magnet create an interfering magnetic circuit. This magnetic circuit acts on the magnetic sensitive element, causing the like poles of the internal pins of the magnetic sensitive element to repel each other, thereby disconnecting the circuit where the magnetic sensitive element is located. At this time, the system is in a non-working state, avoiding unnecessary power consumption and misoperation. When the cover 6 is opened, the first magnet moves with the cover 6, and the magnetic circuit between the first magnet and the second magnet changes. This change causes the internal pins of the magnetic sensitive element to attract under the action of magnetic force, thereby connecting the circuit where the magnetic sensitive element is located. At this time, the system switches to the working state, realizing intelligent switching of the system's working state. There is no need to manually operate complex mechanical switches, improving the convenience and intelligence of use.

[0033] In this embodiment, the control and monitoring structure can further display the dosage or remaining amount of medicine in the medicine storage structure in real time according to the signal of the sensing and triggering structure, so that the user can clearly know the usage of the medicine and avoid overdosing or underdosing; and automatically stop the medicine spraying action after a single medication process is completed to prevent repeated spraying of medicine; and issue an alarm prompt to inform the user in a timely manner that the medication is completed, thereby realizing intelligent monitoring and prompting of the medication process and improving the safety and convenience of medicine use.

[0034] Example 2: A smart pesticide sprayer, manufactured using a smart pesticide spraying system, includes a housing 1, a pesticide bottle 2, a circuit board 3, a reed switch 4, a panel 5, a cap 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 housing 1 has an internal cavity to provide space for the internal structures. The cavity is connected to the nozzle 8, ensuring that the pesticide can be sprayed from the cavity through the nozzle 8. The pesticide bottle 2 and the circuit board 3 are fixed side-by-side and adjacent to each other within the cavity of the housing 1, their close proximity facilitating electrical... Connection and signal transmission; the reed switch 4 is fixed to the surface of the circuit board 3 and participates in circuit on / off control as a magnetic sensitive element; the panel 5 covers one side of the outer shell 1 and corresponds to the position of the circuit board 3, serving as protection and cooperation; the nozzle 8 is integrally formed at the end of the outer shell 1 and is the outlet for the medicine to be sprayed; the cover 6 can be opened and closed to cover the nozzle 8, controlling the opening and closing of the nozzle 8; the first magnet 7 is fixed to the side of the cover 6 facing the nozzle 8 and moves with the cover 6; the second magnet 11 is fixed to the outer surface of the medicine bottle 2 near the pressing end and moves with the medicine bottle 2. The second magnet 11 consists of two magnets with opposite polarities arranged adjacent to each other along the axial direction of the medicine bottle 2, enhancing the sensing effect of magnetic field changes. The unipolar Hall switch 12 is fixed on the circuit board 3 and corresponds to the position of the second magnet 11 to form a sensing adaptation, accurately sensing the magnetic field changes of the second magnet 11. There is a dividing line between the two second magnets 11, and the unipolar Hall switch 12 can only sense one second magnet 11. After pressing the medicine bottle 2, the dividing line enters the sensing area of ​​the unipolar Hall switch 12, and the second second magnet 11 is sensed by the unipolar Hall switch 12, generating a counting logic. The nozzle 13 is integrally formed at the bottom of the cavity of the outer shell 1, and one end of the nozzle 13 is connected to the nozzle 8 to ensure that the agent can flow from the nozzle 13 to the nozzle 8. The other end is inserted and fitted to one end of the medicine bottle 2 so that the agent in the medicine bottle 2 can enter the nozzle 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 agent 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 and participate in the circuit on / off control. The connection relationship between each component is clear and the position matching is precise, which ensures the stable operation of the sprayer and improves the reliability of the overall structure.

[0035] In this embodiment, furthermore, when the cover 6 is closed on the nozzle 8, the relative positions of the first magnet 7 on the cover 6 and the third magnet on the panel 5 form a closed interference magnetic circuit. This magnetic circuit acts on the reed switch 4, causing the two pins inside the reed switch 4 to generate a repulsive force between their like poles, thereby disconnecting the circuit where the reed switch 4 is located. At this time, the sprayer is in a non-working state, avoiding accidental spraying of pesticide. When the cover 6 is opened from the nozzle 8, the first magnet 7 moves synchronously with the cover 6, and the relative positions of the first magnet 7 and the third magnet change, causing the interference magnetic circuit formed by the first magnet 7 and the third magnet to disappear. The magnetic circuit of the third magnet acts solely on the reed switch 4, causing the two pins inside the reed switch 4 to attract under the action of magnetic force, thereby connecting the circuit where the reed switch 4 is located. At this time, the sprayer switches to the working state, realizing the automatic switching of the sprayer's working state and improving the convenience of use.

[0036] In this embodiment, furthermore, when the pressing end of the medicine bottle 2 is pressed, the medicine bottle 2 moves downward along the axial direction under pressure. The movement of the medicine bottle 2 causes the two second magnets 11 fixed on the medicine bottle 2 to move synchronously. The movement of the two second magnets 11 causes the polarity boundary line between the two second magnets 11 to pass through the sensing area of ​​the unipolar Hall switch 12. After sensing the change in the magnetic field, the unipolar Hall switch 12 generates an electrical signal and transmits it to the circuit board 3. The circuit board 3 receives the signal, processes it, and then controls the display screen 9 to display the real-time dosage or remaining percentage change of the medicine in the medicine bottle 2, allowing the user to monitor the medicine status in real time. At the same time, under the pressure generated by pressing, the medicine in the medicine bottle 2 is sprayed out from the nozzle 8 through the nozzle 13, completing the medicine delivery. This process realizes the synchronization of medicine delivery and dosage display, improving the accuracy and visibility of medicine use.

[0037] In this embodiment, the unipolar Hall switch 12 further senses only magnets of a specific polarity. When the portion of the second magnet 11 with that specific polarity passes through the sensing area of ​​the unipolar Hall switch 12, the unipolar Hall switch 12 accurately generates a sensing signal; however, when the portion of the second magnet 11 with the other polarity passes through, the unipolar Hall switch 12 does not generate a sensing signal. This characteristic allows the unipolar Hall switch 12 to accurately identify the movement of the second magnet 11, thereby achieving accurate identification of the movement of the medicine bottle 2 and providing an accurate basis for subsequent precise control of the medicine spraying.

[0038] In this embodiment, further, when a single medication application is completed, that is, after the pressing action of the medicine bottle 2 ends and it resets, the circuit board 3 determines that the medication application has been completed based on the signal transmitted by the single-pole Hall switch 12, and then automatically controls the relevant components to stop the medication spraying action to prevent the medication from continuing to spray out and causing waste or overdose; at the same time, the alarm device on the control circuit board 3 emits a buzzer alarm to promptly remind the user that the single medication application has been completed, avoid repeated medication, and improve the safety and standardization of medication use.

[0039] In addition, the reed switch 4 can also be configured to have a magnet on its end face. A magnetic circuit is formed between the first magnet 7 and the magnet, which reduces the attraction between the two poles inside the reed switch 4, thereby causing the pins of the reed switch 4 to repel each other and achieve the same function.

[0040] The sprayer, as the specific carrier of the system, first achieves working state switching through a magnetic control on / off structure. When the cap 6 closes the nozzle 8, the first magnet 7 on the cap 6 and the third magnet on the panel 5 form an interfering magnetic circuit, causing the reed switch 4 pins on the circuit board 3 to repel each other and disconnect the circuit, and the sprayer is in a non-working state. When the cap 6 is opened, the interfering magnetic circuit disappears, the reed switch 4 pins are attracted and the circuit is connected, and the circuit board 3 enters a standby state. Subsequently, when the user presses the pressing end of the medicine bottle 2, the medicine bottle 2 moves axially and drives the two second magnets 11 with opposite polarities on it to move synchronously, so that the polarity boundary line between the two magnets passes through the sensing area of ​​the unipolar Hall switch 12 on the circuit board 3, and the single-pole Hall switch 12 is activated. The Hall effect switch 12 (which only senses a specific polarity) generates an electrical signal after sensing a change in the magnetic field and transmits it to the circuit board 3. After receiving the signal, the circuit board 3 controls the display screen 9 to display the real-time dosage or remaining percentage of the medicine in the medicine bottle 2. On the other hand, it causes the medicine in the medicine bottle 2 to be sprayed out from the nozzle 8 through the nozzle 13 under the pressure of pressing. When the medicine bottle 2 is reset after a single dose, the polarity boundary line of the second magnet 11 leaves the sensing area, the Hall effect switch 12 stops sending signals, the circuit board 3 determines that the dose has been administered, automatically stops the medicine spraying, and controls the alarm device to emit a buzzer sound. The whole process realizes intelligent operation of the entire process from status recognition to precise spraying and monitoring prompts.

[0041] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.

When the cover is opened, the change in the magnetic circuit of the first magnet and the second magnet causes the internal pins of the magnetically sensitive element to magnetically attract each other and connect the circuit, thereby realizing the switching of the system's working state. The control and monitoring structure can display the changes in dosage or remaining amount of medicine in the medicine storage structure in real time according to the signal of the sensing and triggering structure, and automatically stop the medicine spraying action and issue an alarm prompt after a single medication process is completed, so as to realize intelligent monitoring and prompting of the medication process.

2. A smart pesticide sprayer, manufactured from the smart pesticide spraying system of claim 1, the smart pesticide sprayer comprising a housing, characterized in that, It also includes a medicine bottle, circuit board, reed switch, panel, cap, first magnet, nozzle, display screen, switch, second magnet, unipolar Hall switch, and nozzle; the housing has an internal cavity that communicates with the nozzle; the medicine bottle and circuit board are fixed side-by-side and adjacent to each other within the cavity of the housing; the reed switch is fixed to the surface of the circuit board; the panel covers one side of the housing and corresponds to the position of the circuit board; the nozzle is integrally formed at the end of the housing; the cap is closable and covers the nozzle; the first magnet is fixed to the side of the cap facing the nozzle; and the second magnet is fixed to... On the outer surface of the medicine bottle near the pressing end, the second magnet consists of two magnets with opposite polarities arranged adjacent to each other along the axial direction of the medicine bottle. The unipolar Hall switch is fixed on the circuit board and forms an inductive adaptation corresponding to the position of the second magnet. The nozzle is integrally formed at the bottom of the cavity of the outer shell, and one end of the nozzle is connected to the nozzle and the other end is inserted into one end of the medicine bottle. 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.

3. The intelligent pesticide sprayer according to claim 2, 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.

4. The intelligent pesticide sprayer according to claim 3, 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.

5. The intelligent pesticide sprayer according to claim 4, 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.

6. The intelligent pesticide sprayer according to claim 5, 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.
