Description

Technical Field

[0001] The present invention belongs to the technical field of disinfection devices, and particularly relates to a multifunctional disinfection device. Background Art

[0002] Alcohol disinfection is usually used in public health places, which is relatively convenient and safe. The existing publication number CN112704066B discloses an alcohol disinfection spray and its preparation method. The alcohol disinfection spray includes an alcohol disinfectant solution and a spray device for storing the alcohol disinfectant solution. The spray device compresses the air in the storage bottle through an air pump, so as to continuously spray the misty alcohol disinfectant solution. One side of the top cover is provided with a side pipe, the inside of the side pipe is provided with a universal groove, and a universal head is rotatably connected inside the universal groove. The universal head is used to facilitate the adjustment of the spraying angle of the spray head. The spray head is threadedly connected to the external thread two, so it is convenient to replace and clean the spray head. The existing disclosed spray device controls the spraying of alcohol through air pressure, and it is not easy to control the spraying volume of the alcohol, and the spraying accuracy is relatively low. At the same time, the existing spray device only uses an ordinary spray head, and the spraying effect is poor. It is also not easy to detect the alcohol volume in the storage bottle, and users cannot quickly understand the remaining alcohol volume in the storage bottle. Therefore, it is necessary to design a multifunctional disinfection device to overcome the above difficulties. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention designs a multifunctional disinfection device. The present invention squeezes the pump body through a transmission component, and precisely controls the squeezing position of the transmission component through the cooperation of an induction magnet and a Hall sensor. The negative ion generator and the alcohol in the liquid storage bottle are used for synchronous disinfection, and the spraying effect of the liquid outlet component is better. At the same time, the remaining amount of alcohol in the liquid storage bottle is reliably detected through a liquid level detection component.

[0004] The invention object of the present invention is achieved through the following technical solutions: A multifunctional disinfection device, including a base, a power source component and a liquid storage bottle detachably connected to the base are arranged inside the base. The power source component includes a main control circuit board, a driving motor and a transmission component. A pump body is arranged on the liquid storage bottle. When the driving motor works, it drives the transmission component to squeeze and contact the pump body. The transmission component includes an induction magnet, and a plurality of Hall sensors are arranged on the power source component. A plurality of negative ion generators electrically connected to the main control circuit board are arranged on the main control circuit board. A liquid outlet component is arranged below the base, and the liquid outlet component is connected to the pump body. A liquid level detection component is arranged inside the liquid storage bottle, and an induction circuit board is arranged below the liquid storage bottle.

[0005] Preferably, the power source assembly further includes a movement bottom cover and a movement top cover, which are fixedly connected; a transmission assembly is provided between the movement bottom cover and the movement top cover. The transmission assembly further includes an extrusion member, and an induction magnet is provided on the extrusion member. When the drive motor works, it drives the extrusion member to squeeze and contact the pump body; a plurality of Hall sensors paired with the induction magnet are provided on the movement top cover; a trigger sensor is provided at a position of the base close to the liquid outlet assembly, and the trigger sensor is electrically connected to the main control circuit board.

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

[0007] In the default state, the pump body is not squeezed. At this time, the squeezing end of the squeezing part is far from the pump body, and the Hall sensor at a lower position is aligned with the induction magnet. When the user approaches and triggers the sensor, the trigger sensor sends an electrical signal to the main control circuit board, so that the main control circuit board will control the driving motor to rotate. When the driving motor rotates, it drives the main gear to rotate. The rotation of the main gear drives the first driven gear to rotate, and the rotation of the first driven gear drives the second driven gear to rotate. When the second driven gear rotates, it drives the squeezing part to rotate. After the squeezing part rotates, it will squeeze and contact the pump body. When the squeezing part rotates, it drives the induction magnet to rotate. When the squeezing end of the squeezing part squeezes the pump body, the induction magnet is aligned with the Hall sensor at a higher position. Then the Hall sensor at a higher position will send an electrical signal to the main control circuit board, and the main control circuit board will thus control the driving motor to rotate in the reverse direction. Then the squeezing part will also rotate in the reverse direction, so that the induction magnet approaches the Hall sensor at a lower position, and the Hall sensor at a lower position will send an electrical signal to the main control circuit board, so that the driving motor rotates in the reverse direction. Therefore, by setting the Hall sensor and the induction magnet, the forward and reverse rotation of the squeezing part can be accurately controlled. When the squeezing part rotates forward and backward, it can continuously squeeze the pump body. Because by setting the meshing teeth of the main gear, the first driven gear, the second driven gear and the squeezing part to cooperate with each other, the rotation of the squeezing part is more accurate. After the pump body is squeezed, it can accurately suck out alcohol. At the same time, the driving motor can rotate forward and backward in time, thus well protecting the meshing teeth on the squeezing part and the pump body, and the service life of the squeezing part 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 assembly and then sprayed out through the liquid outlet assembly. A delay switch is provided on the main control circuit board, and the main control circuit board can automatically cut off the power. When the trigger sensor sends an electrical signal to the main control circuit board again, the main control circuit board can work immediately.

[0008] Preferably, a main control circuit board is provided on the lower cover of the movement. Several negative ion generators electrically connected thereto are provided on the side of the main control circuit board. A first circuit board is provided at the end of the lower cover of the movement far from the main control circuit board. The first circuit board is electrically connected to the main control circuit board. Several negative ion generators electrically connected thereto are also provided on the first circuit board. Several installation card slots are provided at the edges of the lower cover and the upper cover of the movement. The negative ion generators are all arranged in the installation card slots. The negative ion generators extend along the installation card slots towards the edge of the base.

[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 generators start to work. When the negative ion generators work, they generate positive ions and negative ions. When the positive and negative charges are neutralized in the air, a huge amount of energy is released instantly, which causes the change of the bacterial structure and the transfer of energy around them, resulting in the death of bacteria and achieving the sterilization effect. Negative ion generators are provided on both the left and right sides of the base, so that the coverage area is wider. The sterilization and disinfection effect is better by cooperating with alcohol with the negative ion generators.

[0010] Preferably, the lower cover of the movement is mounted on the base. A limit card slot is provided at the edge of the base, and the edge of the lower cover of the movement is arranged in the limit card slot. A liquid storage bottle is provided directly below the lower cover of the movement and the upper cover of the movement. The liquid storage bottle is arranged in a fitting manner with the upper cover of the movement. A limit retaining strip is provided on the base, and the liquid storage bottle is arranged in a fitting manner with the limit retaining strip. A battery holder is provided on the lower cover of the movement. An opening end of the battery holder is provided with a battery cover which is connected to the battery holder in a snap-fit manner. A limit projection is provided on the battery holder, and an elastic snap is provided on the battery cover which is elastically connected to the limit projection. When the battery cover is closed with the battery holder, the elastic snap is mounted on the limit projection. A power adapter is further provided on the lower cover of the movement, and the power adapter is electrically connected to the main control circuit board.

[0011] By providing the limit card slot and the limit retaining strip, it is convenient to disassemble and assemble the power source assembly and the liquid storage bottle, which is convenient for adding new alcohol into the liquid storage bottle. By providing the battery cover and the battery holder, it is convenient to replace the battery. In the default state, the elastic snap is stuck on the limit projection. When the elastic snap is pressed, the elastic snap disengages from the limit projection, so that the battery cover can be opened, thus facilitating the replacement of the battery. By providing the power adapter, it is convenient to connect to an external power socket.

[0012] Preferably, a guide post perpendicular to the liquid storage bottle is provided in the liquid storage bottle. A first strip-shaped protrusion is provided on the guide post. The liquid level detection assembly includes a first float and a second float, and the first float and the second float are connected in a snap-fit manner. The first float and the second float are sleeved and mounted on the guide post. A first magnet is provided at the bottom of the first float, and a reed switch sensor electrically connected to the first magnet is provided on the induction circuit board. The reed switch sensor is arranged facing the first magnet, and the induction circuit board is electrically connected to the main control circuit board.

[0013] Preferably, a first card slot is provided on the first float, and a first protrusion is provided on the second float. The contour of the first protrusion is mutually adapted to the contour of the first card slot. When the first float and the second float are fitted and mounted, the first protrusion is arranged in the first card slot. A concave portion is provided on the second float, and the first strip-shaped protrusion is stuck in the concave portion. The contour of the first strip-shaped protrusion is mutually adapted to the contour of the concave portion. An LED induction lamp is provided on the main control circuit board. The liquid storage bottle is detachably mounted on the base, and a face cover detachably connected to the base is provided on the base. An LED light guide column is provided at the end of the base close to the LED induction lamp. The liquid storage bottle is transparent, and the face cover is provided with a transparent liquid level observation strip which extends along the axial direction of the liquid storage bottle.

[0014] The first float is provided with a first card slot, and the second float is provided with a first protrusion. The contour of the first protrusion is adapted to that of the first card slot, which facilitates the installation of the liquid level detection component onto the guide post. By providing the first strip-shaped protrusion and the concave portion, the liquid level detection component can only move up and down along the guide post; the liquid level detection component will not rotate, ensuring that the first magnet always faces the reed switch sensor. When the remaining alcohol volume in the liquid storage bottle is small, the liquid level detection component is arranged close to the bottom of the liquid storage bottle at this time; in this way, the first magnet will approach the reed switch sensor synchronously, and when the reed switch sensor is induced, it will send an electrical signal to the main control circuit board through the induction circuit board, so that the LED induction lamp will be in a flashing state, thereby reminding the user to add alcohol. By providing the LED light guide column, the flashing of the LED induction lamp is more obvious and intuitive. After alcohol is re-added to the liquid storage bottle, the liquid level detection component floats synchronously with the alcohol liquid level, so that the LED induction lamp will stop flashing. The remaining alcohol volume in the liquid storage bottle can also be observed through the liquid level observation strip. In combination with the flashing of the LED induction lamp, the alcohol volume monitoring is safer and more reliable.

[0015] Preferably, the liquid outlet component includes a nozzle mounting plate, a pipeline connector, a nozzle main body part and a disinfection nozzle; the nozzle mounting plate is mounted on the base; the bottom of the disinfection nozzle is mounted on the nozzle mounting plate, and the top of the disinfection nozzle extends and is mounted inside the nozzle main body part. The edge of the nozzle main body part is mounted on the base, and the nozzle main body part is snap-connected to the disinfection nozzle; the liquid inlet end of the nozzle main body part is connected to the pipeline connector, and a disinfection connecting pipe is provided between the pipeline connector and the pump body; an installation bushing is provided inside the disinfection nozzle, and a movable plug is provided between the installation bushing and the nozzle main body part, and a spring is provided between the movable plug and the installation bushing.

[0016] Preferably, a liquid flow channel is provided inside the nozzle main body part, and a movable plug is provided between the end of the liquid flow channel and the installation bushing; a first step is provided inside the installation bushing, one end of the spring abuts against the first step, and the other end of the spring abuts against the protrusion of the movable plug; by default, the spring is in a compressed state and the protrusion of the movable plug blocks the liquid flow channel; a number of uniformly distributed second strip-shaped protrusions are provided on the outer wall of the installation bushing, and the second strip-shaped protrusions abut against the inner wall of the disinfection nozzle; a gap for liquid flow is formed between any two of the second strip-shaped protrusions; a second step is provided on the disinfection nozzle, and the bottom of the installation bushing abuts against the second step; a liquid outlet is provided at the bottom of the disinfection nozzle, and a number of spiral flow channels are provided on the inner wall of the second step. The spiral flow channels are circumferentially arranged along the liquid outlet and the spiral flow channels communicate with the liquid outlet.

[0017] In the default state, the spring is in a compressed state, and the movable plug abuts against the liquid flow channel, so that the alcohol in the liquid flow channel cannot overflow. When the pump body works, the alcohol enters the liquid flow channel through the disinfection connecting pipe; 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-shaped protrusions; because the spiral flow channels are distributed in a circumferential array along the liquid outlet, the alcohol can present a better spray shape when spraying out from the liquid outlet, and the spraying effect is better. When the pump body stops working, the movable plug automatically abuts against 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.

[0018] Preferably, a face cover detachably connected to the base is provided on the base, and a locking assembly is provided between the face cover and the base; the locking assembly includes a locking seat, a lock core and a lock hook, and the locking seat is snap-fitted on the face cover; a lock core rotatably connected to the locking seat is provided in the locking seat, and a lock hook is sleeved and installed on the outer layer of the lock core; a locking slot for installing the lock hook is provided on the base, and the end of the lock hook faces the locking slot.

[0019] In the default state, the lock hook is stuck in the locking slot, so that the locking assembly is in a locked state, and the face cover cannot be disassembled from the base, thereby protecting the components inside the base and the face cover. When the face cover needs to be opened, the lock core is rotated by a key, so that the lock core rotates relative to the locking seat; when the lock core rotates, it will catch the lock hook, so that the lock core can drive the lock hook to rotate synchronously, so that the lock hook is disengaged from the locking slot. At the same time, when the face cover needs to be locked, the lock core is rotated in the reverse direction, so that the lock hook is re-stuck in the locking slot.

[0020] Compared with the prior art, the present invention has the following beneficial effects: 1. The gear on the transmission component drives the extrusion part to rotate, so as to repeatedly extrude the pump body; the extrusion synchronization of the pump body is good, so that the capacity of the alcohol extracted by the pump body is more accurate, the extraction accuracy is better, and the alcohol spraying amount can be controlled according to the use space, and the versatility is better; 2. The alcohol and the negative ion generator cooperate with each other for sterilization and disinfection, and the disinfection effect is better and reliable; 3. The liquid outlet component enables the alcohol to be sprayed in a mist shape, and the alcohol spraying effect is good, and the use environment is quickly covered by the mist-shaped alcohol; 4. The liquid level detection component is convenient for detecting the remaining capacity of the alcohol in the liquid storage bottle and automatically reminding the user to add alcohol; 5. The base and the face cover are locked by the locking component, and the use is safer and more reliable. The liquid storage bottle with alcohol can only be taken out and replaced by the user's key.

When the second driven gear 236 rotates, it drives the squeezing member 232 to rotate. After the squeezing member 232 rotates, it will squeeze and contact the pump body 4. When the squeezing member 232 rotates, it drives the induction magnet 231 to rotate. When the squeezing end of the squeezing member 232 squeezes the pump body 4, the induction magnet 231 is aligned with the Hall sensor 24 in the upper position. Then the Hall sensor 24 in the upper position will send an electrical signal to the main control circuit board 21, and the main control circuit board 21 will thus control the driving motor 22 to rotate in the reverse direction. Then the squeezing member 232 will also rotate in the reverse direction, so that the induction magnet 231 approaches the Hall sensor 24 in the lower position. The Hall sensor 24 in the lower position will send an electrical signal to the main control circuit board 21, so that the driving motor 22 rotates in the reverse direction. Therefore, by setting the Hall sensor 24 and the induction magnet 231, the forward and reverse rotation of the squeezing member 232 can be accurately controlled. When the squeezing member 232 rotates forward and backward, it can continuously squeeze the pump body 4. Because by setting the meshing teeth of the main gear 234, the first driven gear 235, the second driven gear 236 and the squeezing member 232 to cooperate with each other, the rotation of the squeezing member 232 is more accurate. After the pump body 4 is squeezed, it can accurately suck out the alcohol. At the same time, the driving motor 22 can rotate forward and backward in time, thus well protecting the meshing teeth on the squeezing member 232 and the pump body 4, and the service life of the squeezing 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 assembly 6 and then sprayed out through the liquid outlet assembly 6. A delay switch 211 is provided on the main control circuit board 21, 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.

[0042] 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. When the negative ion generator 5 works, it generates positive ions and negative ions. When the positive and negative charges are neutralized in the air, a huge amount of energy is released instantly, which causes the change of the bacterial structure and the transfer of energy around it, resulting in the death of bacteria and achieving the sterilization effect. Negative ion generators 5 are provided on both the left and right sides of the base 1, so that the coverage area is wider. The combination of the negative ion generator 5 and alcohol for disinfection has a better effect.

[0043] The working principle of the liquid level detection component 7 is as follows. A first card slot 74 is provided on the first float 71, and a first protrusion 75 is provided on the second float 72; the contour of the first protrusion 75 is adapted to that of the first card slot 74, which facilitates the installation of the liquid level detection component 7 onto the guide post 31; by providing the first strip-shaped protrusion 32 and the concave portion 76, the liquid level detection component 7 can only move up and down along the guide post 31; the liquid level detection component 7 will not rotate, ensuring that the first magnet 73 always faces the reed switch sensor 81; when the remaining alcohol volume in the liquid storage bottle 3 is small, at this time the liquid level detection component 7 is arranged close to the bottom of the liquid storage bottle 3; in this way, the first magnet 73 will approach the reed switch sensor 81 synchronously, and when the reed switch sensor 81 is induced, it will send an electrical signal to the main control circuit board 21 through the induction circuit board 8, so that the LED induction lamp 17 will be in a flashing state, thereby reminding the user to add alcohol. By providing the LED light guide column 18, the flashing of the LED induction lamp 17 is more obvious and intuitive. When alcohol is re-added to the liquid storage bottle 3, the liquid level detection component 7 floats synchronously with the alcohol liquid level, so that the LED induction lamp 17 will stop flashing. The remaining alcohol volume in the liquid storage bottle 3 can also be observed through the liquid level observation strip 19. Cooperating with the flashing of the LED induction lamp 17, the alcohol volume monitoring is safer and more reliable.

[0044] Under the default state, the spring 68 is in a compressed state, and the movable plug 67 abuts against the liquid flow channel 69, so that the alcohol in the liquid flow channel 69 cannot overflow. When the pump body 4 works, alcohol enters the liquid flow channel 69 through the disinfection connecting pipe 65; the alcohol will push the movable plug 67, so that the liquid flow channel 69 will automatically open; then the alcohol flows into the spiral flow channel 614 along the gap between the second strip-shaped protrusions 611; because the spiral flow channel 614 is circumferentially arranged around the liquid outlet 613, the alcohol can present a better spray shape when spraying out from the liquid outlet 613, and the spraying effect is better. When the pump body 4 stops working, the movable plug 67 automatically abuts against 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.
