At the same time, the existing spray device only uses an ordinary spray head, and the spray effect is poor. The alcohol capacity in the storage bottle is also difficult to detect, and the user cannot quickly understand the remaining alcohol capacity in the storage bottle. Therefore, it is necessary to design a multifunctional disinfection device to overcome the above difficulties. Summary of the invention

[0004] The inventive objective of the present invention is achieved through the following technical solutions: a multifunctional disinfection device, comprising a base, wherein a power source assembly and a liquid storage bottle detachably connected thereto are arranged in the base, the power source assembly comprising a main control circuit board, a drive motor and a transmission assembly, a pump body is arranged on the liquid storage bottle, and when the drive motor is working, the drive transmission assembly is driven to squeeze and contact the pump body; the transmission assembly comprises an induction magnet, and a plurality of Hall sensors are arranged on the power source assembly; a plurality of negative ion generators electrically connected thereto are arranged on the main control circuit board; a liquid outlet assembly is arranged below the base, and the liquid outlet assembly is connected to the pump body; a liquid level detection assembly is arranged in the liquid storage bottle, and an induction circuit board is arranged below the liquid storage bottle.

[0005] Preferably, the power source assembly also includes a movement lower cover and a movement upper cover, which are fixedly connected; a transmission assembly is provided between the movement lower cover and the movement upper cover, and the transmission assembly includes an extrusion piece, on which is provided an induction magnet, and when the drive motor is working, it drives the extrusion piece to squeeze and contact the pump body; a plurality of Hall sensors paired with the induction magnets are provided on the movement upper cover; a trigger sensor is provided at a position of the base near the liquid outlet assembly, and the trigger sensor is electrically connected to the main control circuit board.

[0006] Preferably, the transmission assembly includes a gear plate, a main gear, a first driven gear and a second driven gear; the gear plate is installed on the driving motor, and the main gear is connected to the driving motor; the first driven gear, the second driven gear and the extrusion piece are all rotatably connected to the gear plate; the main gear is meshed with the first driven gear, and the first driven gear is meshed with the second driven gear; the second driven gear is meshed with the extrusion piece; an arc groove is provided in the extrusion piece, and an induction magnet is provided in the arc groove; the induction magnet is arranged close to the meshing teeth on the extrusion piece, and the movement cover is provided with an arc mounting strip, and Hall sensors are respectively provided at both ends of the arc mounting strip, and the Hall sensors are distributed on the rotation track of the induction magnet; the Hall sensor is electrically connected to the main control circuit board.

[0007] In the default state, the pump body is not squeezed, at which time the squeezing end of the squeezing piece is away from the pump body, and the Hall sensor at the lower position is aligned with the inductive magnet; when the user approaches the trigger sensor, the trigger sensor sends an electrical signal to the main control circuit board, so that the main control circuit board will control the drive motor to rotate; when the drive motor rotates, it drives the main gear to rotate, the main gear rotates to drive the first driven gear to rotate, and the first driven gear rotates to drive the second driven gear to rotate; when the second driven gear rotates, it drives the squeezing piece to rotate, and after the squeezing piece rotates, it squeezes and contacts the pump body; when the squeezing piece rotates, it drives the inductive magnet to rotate, and when the squeezing end of the squeezing piece squeezes the pump body, the inductive magnet is aligned with the Hall sensor at the higher position; then the Hall sensor at the higher position will send an electrical signal to the main control circuit board, and the main control circuit board will control the drive motor to rotate in the opposite direction; then the squeezing piece will also rotate in the opposite direction, so that the inductive magnet approaches the Hall sensor at the lower position, and the Hall sensor at the lower position will send an electrical signal to the main control circuit board, so that the drive motor rotates in the opposite direction; therefore, by setting the Hall sensor and the inductive magnet, the forward and reverse rotation of the squeezing piece can be accurately controlled, and the pump body can be continuously squeezed when the squeezing piece is reversed. Because the meshing teeth of the main gear, the first driven gear, the second driven gear and the extrusion piece cooperate with each other, the rotation of the extrusion piece is more accurate, and the alcohol can be accurately sucked out after the pump body is squeezed. At the same time, the drive motor can rotate forward and reverse in time, thereby well protecting the meshing teeth on the extrusion piece and the pump body, and the service life of the extrusion piece and the pump body is longer. After the pump body is repeatedly squeezed, the alcohol can be quantitatively extracted from the liquid storage bottle into the liquid outlet component, and then sprayed out through the liquid outlet component; a delay switch is provided on the main control circuit board, and the main control circuit board can automatically power off.

[0009] When the trigger sensor sends an electrical signal to the main control circuit board, the main control circuit board and the first circuit board work synchronously, so that the negative ion generator starts to work; the negative ion generator generates positive ions and negative ions when working, and releases huge energy at the moment of neutralization of positive and negative charges in the air, which causes changes in the structure of bacteria around it and transfers energy, thereby causing the bacteria to die and achieve the effect of sterilization. Negative ion generators are set on both sides of the base, so that the coverage area is wider. The sterilization and disinfection effect is better through the combination of negative ion generators and alcohol.

[0010] Preferably, the movement lower cover is installed on the base, and a limit slot is provided on the edge of the base, and the edge of the movement lower cover is arranged in the limit slot; a liquid storage bottle is provided directly below the movement lower cover and the movement upper cover, and the liquid storage bottle is fitted with the movement upper cover, and a limit stop bar is provided on the base, and the liquid storage bottle is fitted with the limit stop bar; a battery seat is provided on the movement lower cover, and a battery cover is provided at the open end of the battery seat with a snap connected to it; a limit protrusion is provided on the battery seat, and an elastic snap is provided on the battery cover with an elastic snap elastically connected to it; when the battery cover and the battery seat are covered, the elastic snap is installed on the limit protrusion; a power adapter is also provided on the movement lower cover, and the power adapter is electrically connected to the main control circuit board.

By setting the battery cover and battery holder, it is convenient to replace the battery; the elastic buckle is stuck on the limit protrusion in the default state, and the elastic buckle is disengaged from the limit protrusion when the elastic buckle is pressed, so that the battery cover can be opened, thereby facilitating battery replacement.

[0013] Preferably, the first float is provided with a first slot, and the second float is provided with a first protrusion, and the first protrusion and the contour of the first slot are mutually adapted; when the first float and the second float are installed in a close relationship, the first protrusion is arranged in the first slot; the second float is provided with a recessed portion, and the first strip protrusion is stuck on the recessed portion, and the contour of the first strip protrusion and the contour of the recessed portion are mutually adapted; the main control circuit board is provided with an LED sensor lamp, the liquid storage bottle is detachably mounted on the base, and the base is provided with a surface cover detachably connected thereto; an LED light guide column is provided at the end of the base close to the LED sensor lamp; the liquid storage bottle is transparent, and the surface cover is provided with a transparent liquid level observation strip, and the liquid level observation strip extends along the axial direction of the liquid storage bottle.

[0014] The first float is provided with a first slot, and the second float is provided with a first protrusion, and the first protrusion and the first slot are adapted to each other, so that it is convenient to install the liquid level detection component on the guide column; by setting the first strip protrusion and the inner concave part, the liquid level detection component can only move up and down along the guide column; the liquid level detection component will not rotate, ensuring that the first magnet is always facing the reed switch sensor; when the remaining alcohol capacity in the liquid storage bottle is not much, the liquid level detection component is set close to the bottom of the liquid storage bottle; in this way, the first magnet will be synchronously close to the reed switch sensor, and the reed switch sensor will send an electrical signal to the main control circuit board through the induction circuit board when it is induced, so that the LED induction light will be in a flashing state, thereby reminding the user to add alcohol. By setting the LED light guide column, the flashing of the LED induction light is more obvious and intuitive. When alcohol is added to the liquid storage bottle again, the liquid level detection component floats synchronously with the alcohol liquid level, so that the LED induction light will stop flashing. The remaining alcohol capacity in the liquid storage bottle can also be observed through the liquid level observation bar, and the LED induction light flashes, so that the alcohol capacity monitoring is safer and more reliable.

[0015] Preferably, the liquid outlet assembly comprises a nozzle mounting plate, a pipe connector, a nozzle main body and a disinfecting nozzle; the nozzle mounting plate is mounted on a base; the bottom of the disinfecting nozzle is mounted on the nozzle mounting plate, the top of the disinfecting nozzle is extended and mounted in the nozzle main body, the edge of the nozzle main body is mounted on the base, and the nozzle main body is snap-connected to the disinfecting nozzle; the liquid inlet end of the nozzle main body is connected to the pipe connector, and a disinfecting connecting pipe is provided between the pipe connector and the pump body; a mounting sleeve is provided in the disinfecting nozzle, a movable plug is provided between the mounting sleeve and the nozzle main body, and a spring is provided between the movable plug and the mounting sleeve.

[0017] In the default state, the spring is in a compressed state, and the movable plug rests on the liquid flow channel, so that the alcohol in the liquid flow channel cannot overflow. When the pump body is working, alcohol enters the liquid flow channel through the disinfection connecting tube; the alcohol will push the movable plug, so that the liquid flow channel will automatically open; then the alcohol flows into the spiral flow channel along the gap between the second strip protrusions; because the spiral flow channel is distributed along the circumference of the liquid outlet, the alcohol can be sprayed out of the liquid outlet in a better spray shape and have a better spray effect. When the pump body stops working, the movable plug automatically rests on the liquid flow channel under the action of the spring, so that the liquid flow channel is in a closed state and the alcohol cannot overflow.

When the cover needs to be opened, the lock cylinder is turned with the key, so that the lock cylinder rotates relative to the locking seat; when the lock cylinder rotates, the lock hook is stuck, so that the lock cylinder can synchronously drive the lock hook to rotate, so that the lock hook is disengaged from the locking slot. At the same time, when the cover needs to be locked, the lock cylinder is turned in the opposite direction, so that the lock hook is stuck in the locking slot again.

[0027] The specific operation process of this embodiment is as follows: in the default state, the pump body 4 is not squeezed, at this time, the squeezing end of the squeezing piece 232 is away from the pump body 4, and the Hall sensor 24 which is lower than the pump body 4 is aligned with the induction magnet 231; when the user approaches the trigger sensor 10, the trigger sensor 10 sends an electrical signal to the main control circuit board 21, so that the main control circuit board 21 will control the drive motor 22 to rotate; when the drive motor 22 rotates, it drives the main gear 234 to rotate, and the main gear 234 rotates to drive the first driven gear 235 to rotate, and the first driven gear 235 rotates to drive the second driven gear 236 to rotate; when the second driven gear 236 rotates, it drives the squeezing piece 232 to rotate, and when the squeezing piece 232 rotates, it will squeeze and contact the pump body 4; the squeezing piece 232 rotates When the pump body 4 is pressed, the induction magnet 231 is driven to rotate, and when the extrusion end of the extrusion piece 232 squeezes the pump body 4, the induction magnet 231 is aligned with the Hall sensor 24 at a high position; then the Hall sensor 24 at a high position will send an electrical signal to the main control circuit board 21, and the main control circuit board 21 will control the drive motor 22 to rotate in the opposite direction; then the extrusion piece 232 will also rotate in the opposite direction, so that the induction magnet 231 is close to the Hall sensor 24 at a low position, and the Hall sensor 24 at a low position will send an electrical signal to the main control circuit board 21, so that the drive motor 22 rotates in the opposite direction; therefore, by setting the Hall sensor 24 and the induction magnet 231, the positive and negative rotation of the extrusion piece 232 can be accurately controlled, and the extrusion piece 232 can continuously squeeze the pump body 4 when it is positive and negative. Because the meshing teeth of the main gear 234, the first driven gear 235, the second driven gear 236 and the extrusion piece 232 cooperate with each other, the rotation of the extrusion piece 232 is more accurate, and the alcohol can be accurately sucked out after the pump body 4 is squeezed. At the same time, the driving motor 22 can rotate forward and reverse in time, thereby well protecting the meshing teeth on the extrusion member 232 and the pump body 4, and the service life of the extrusion member 232 and the pump body 4 is longer. After the pump body 4 is repeatedly squeezed, the alcohol can be quantitatively extracted from the liquid storage bottle 3 into the liquid outlet component 6, and then sprayed out through the liquid outlet component 6; the main control circuit board 21 is provided with a delay switch 211, and the main control circuit board 21 can automatically cut off the power. When the trigger sensor 10 sends an electrical signal to the main control circuit board 21 again, the main control circuit board 21 can work immediately again.

[0028] When the trigger sensor 10 sends an electrical signal to the main control circuit board 21, the main control circuit board 21 and the first circuit board 12 work synchronously, so that the negative ion generator 5 starts to work; the negative ion generator 5 generates positive ions and negative ions when working, and releases huge energy at the moment of neutralization of positive and negative charges in the air, thereby causing changes in the structure of bacteria around it and energy transfer, thereby causing the death of bacteria and achieving the effect of sterilization. Negative ion generators 5 are provided on both sides of the base 1, so that the coverage area is wider. The negative ion generator 5 and alcohol are used in combination for sterilization and disinfection, and the effect is better.

[0029] The working principle of the liquid level detection assembly 7 is as follows: the first float 71 is provided with a first slot 74, and the second float 72 is provided with a first protrusion 75; the first protrusion 75 and the first slot 74 are adapted to each other, so that it is convenient to install the liquid level detection assembly 7 on the guide column 31; by setting the first strip protrusion 32 and the inner recess 76, the liquid level detection assembly 7 can only move up and down along the guide column 31; the liquid level detection assembly 7 will not rotate, ensuring that the first magnet 73 is always facing the reed switch sensor 81; when the alcohol remaining capacity in the liquid storage bottle 3 is not much, the liquid level detection assembly 7 is set close to the bottom of the liquid storage bottle 3; in this way, the first magnet 73 will synchronously approach the reed switch sensor 81, and the reed switch sensor 81 will be induced to send an electrical signal to the main control circuit board 21 through the induction circuit board 8, so that the LED sensor light 17 will be in a flashing state, thereby reminding the user to add alcohol. By setting the LED light guide column 18, the flashing of the LED sensor light 17 is more obvious and intuitive. When alcohol is added to the liquid storage bottle 3, the liquid level detection component 7 rises synchronously with the alcohol level, so that the LED sensor lamp 17 stops flashing. The remaining alcohol capacity in the liquid storage bottle 3 can also be observed through the liquid level observation bar 19, and the LED sensor lamp 17 flashes, so that the alcohol capacity monitoring is safer and more reliable.

[0030] In the default state, the spring 68 is in a compressed state, and the movable plug 67 rests on the liquid flow channel 69, so that the alcohol in the liquid flow channel 69 cannot overflow. When the pump body 4 is working, the alcohol enters the liquid flow channel 69 through the disinfection connecting tube 65; the alcohol will push the movable plug 67, so that the liquid flow channel 69 will automatically open; then the alcohol flows along the gap between the second strip protrusions 611 into the spiral flow channel 614; because the spiral flow channel 614 is distributed along the circumference of the liquid outlet 613, the alcohol can be sprayed out from the liquid outlet 613 in a better spray shape, and the spraying effect is better. When the pump body 4 stops working, the movable plug 67 automatically rests on the liquid flow channel 69 under the action of the spring 68, so that the liquid flow channel 69 is in a closed state, and the alcohol cannot overflow.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
