Therefore, car vacuum cleaners and car sterilizers are usually installed in cars. The car vacuum cleaner is used for vacuuming, and the car sterilizer is used for disinfection. In the current technology, car vacuum cleaners and car sterilizers are usually set up as two separate devices. On the one hand, they take up space in the car, and on the other hand, they increase the cost of use. Moreover, after long-term use, the filter of the car vacuum cleaner will accumulate a lot of dust and bacteria. If it needs to be cleaned and disinfected, the filter needs to be removed, which is quite cumbersome. Summary of the Invention

Furthermore, after long-term use, the filter of the vehicle vacuum cleaner will accumulate a lot of dust and bacteria, and if it needs to be cleaned and disinfected, the filter needs to be removed, which is quite cumbersome.
[0004] A vehicle interior cleaning and disinfection device includes a cleaning component and a disinfection component. The cleaning component includes a fixed cylinder, a cleaning cylinder, a reversible fan, and a filter screen. The reversible fan is fixedly connected inside the fixed cylinder. A filter screen is rotatably connected inside the fixed cylinder, and the filter screen has a flow guiding structure that allows the filter screen to rotate. The edge of the filter screen is in contact with the inner wall of the fixed cylinder. The cleaning cylinder is detachably fixedly connected to one end of the fixed cylinder, and the cleaning cylinder has a dust suction port at one end. The other end of the fixed cylinder has a vent. The disinfection component includes... The device includes a disinfection tank and an atomizer fixed to the disinfection tank. The disinfection tank is detachably fixed to a fixed cylinder, and the air outlet of the atomizer extends into the fixed cylinder. The air outlet of the atomizer is located between the filter screen and the forward and reverse rotating fan, and the atomizer is provided with a pressure structure corresponding to the flow guiding structure. When the forward and reverse rotating fan rotates forward, the cleaning component performs dust suction, and the pressure structure presses against the flow guiding structure to fix the filter screen to filter particulate matter. When the forward and reverse rotating fan rotates in reverse, the disinfection component performs disinfection, and the blowing guide mechanism drives the filter screen to rotate to remove and disinfect the dust on the surface of the filter screen.
[0005] Preferably, the lower side of the fixed cylinder is provided with a threaded interface, the top of the disinfection tank is provided with a fixed connector, the edge thread of the atomizer engages with the inner wall of the fixed connector, and the outer wall of the fixed connector engages with the threaded interface.
[0006] Preferably, the flow guiding structure includes a flow guiding arc plate, the pressing structure includes a pressure plate, a flow guiding arc plate is fixedly connected to each side of the filter screen, and the protruding end of the flow guiding arc plate extends above the threaded interface. A pressure plate is fixedly connected to the air outlet of the atomizer along its circumference. During cleaning, the disinfection water tank is rotated, which moves the atomizer and the pressure plate into the fixed cylinder and presses the pressure plate against the bottom of the flow guiding arc plate. The pressure plate is between the bottom wall of the fixed cylinder and the bottom wall of the fixed cylinder. During disinfection, the disinfection water tank is rotated, which moves the atomizer and the pressure plate outward and moves the pressure plate away from the flow guiding arc plate.
[0007] Preferably, the inner wall of the fixed cylinder has a rotating groove, and the edge of the filter screen has a protrusion that is inserted into the rotating groove and rotatably connected to the rotating groove. A torsion spring is fixedly connected between the protrusion and the rotating groove.
[0008] Preferably, the atomizer includes a piezoelectric ceramic plate and a fixed shell. The piezoelectric ceramic plate is disposed inside the fixed shell. The air outlet is opened at the top of the fixed shell. The cotton strip is provided at the bottom of the fixed shell, with one end of the cotton strip attached to the piezoelectric ceramic plate and the other end of the cotton strip extending out of the fixed shell and inserted into the disinfection water tank. The outer wall of the fixed shell is engaged with the inner wall of the fixed connector by threads.

[0011] The present invention has the following advantages:
[0012] (1) This invention includes a cleaning component and a disinfection component. During cleaning, the forward and reverse fan rotates forward to draw air from the outside into the fixed cylinder, and then discharges it from the vent. During the air intake process, dust or dirt is drawn into the fixed cylinder from the suction port. Since the fixed cylinder is equipped with a filter screen, large dust particles will be blocked inside the cleaning cylinder. The dust inside the cleaning cylinder can then be emptied directly. During disinfection, the forward and reverse fan rotates in reverse to draw air from the vent into the fixed cylinder, and then discharges it from the suction port. During the rotation of the forward and reverse fans, the atomizer atomizes the disinfectant solution inside the disinfectant tank and delivers it to the fixed cylinder. Under the blowing of the forward and reverse fans, the atomized disinfectant solution is delivered to the external environment through the suction port. The suction port can be aimed at any corner inside the vehicle, including the edges of the seat cushions and floor mats, as needed, so that the disinfection effect is better and more comprehensive. This invention integrates the disinfection component and the suction component into one device, which can both vacuum and disinfect, has a lower operating cost, and does not take up too much space inside the vehicle.
[0013] (2) When the atomized disinfectant is discharged from the dust suction port, the disinfectant will also come into contact with the inner wall of the cleaning cylinder, thus disinfecting the cleaning cylinder. Furthermore, under the blowing of the forward and reverse fan, the guide structure will drive the filter screen to rotate. During the rotation, the filter screen will fully come into contact with the atomized disinfectant. There is no need to disassemble and clean the filter screen afterward, making the use process more convenient. Attached Figure Description

[0019] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention.
[0020] like Figure 1-4 As shown, this invention provides a vehicle interior cleaning and disinfection device, including a cleaning component and a disinfection component. The cleaning component includes a fixed cylinder 1, a cleaning cylinder 2, a forward and reverse fan 3, and a filter screen 4. The forward and reverse fan 3 is fixedly connected inside the fixed cylinder 1. A filter screen 4 is rotatably connected inside the fixed cylinder 1, and the filter screen 4 has a flow guiding structure that allows the filter screen 4 to rotate. The edge of the filter screen 4 is in contact with the inner wall of the fixed cylinder 1. The cleaning cylinder 2 is detachably fixedly connected to one end of the fixed cylinder 1, and the end of the cleaning cylinder 2 has a dust suction port. The other end of the fixed cylinder 1 has a vent 16. The disinfection component includes a disinfection water tank 8 and a disinfection water tank 8 fixed to the cleaning cylinder 2. The atomizer 11 is detachably fixed to the fixed cylinder 1, and the air outlet of the atomizer 11 extends into the fixed cylinder 1. The air outlet of the atomizer 11 is located between the filter screen 4 and the forward and reverse fan 3. The atomizer 11 is provided with a pressure structure corresponding to the flow guiding structure. When the forward and reverse fan 3 rotates forward, the cleaning component performs dust suction and the pressure structure presses against the flow guiding structure to fix the filter screen to filter particulate matter. When the forward and reverse fan 3 rotates in reverse, the disinfection component performs disinfection and blows the filter screen 4 to rotate to remove and disinfect the dust on the surface of the filter screen 4.
[0021] The lower side of the fixed cylinder 1 is provided with a threaded interface 9, and the top of the disinfection tank 8 is provided with a fixed connector 10. The edge thread of the atomizer 11 engages with the inner wall of the fixed connector 10, and the outer wall of the fixed connector 10 engages with the threaded interface 9. The engagement of the atomizer 11 with the internal thread of the fixed connector 10 enables the detachable fixing of the atomizer 11. If the atomizer 11 is damaged, it can be repaired or replaced. The engagement of the outer wall of the fixed connector 10 with the threaded interface 9 enables the detachable fixing of the disinfection tank 8, so as to replenish the disinfectant solution in a timely manner.
[0022] The flow guiding structure includes a flow guiding arc plate 6, and the pressing structure includes a pressure plate 7. The filter screen 4 is fixedly connected to both sides of the flow guiding arc plate 6, and the extended end of the flow guiding arc plate 6 extends above the threaded interface 9. The atomizer 11 is fixedly connected to a pressure plate 7 along its circumference at the air outlet. During cleaning, the disinfection water tank 8 is rotated, which moves the atomizer 11 and the pressure plate 7 into the interior of the fixed cylinder and presses the pressure plate 7 against the bottom of the flow guiding arc plate 6. The pressure plate 7 is between the bottom wall of the fixed cylinder 1 and the bottom wall of the fixed cylinder 1. During disinfection, the disinfection water tank is rotated, which moves the atomizer 11 and the pressure plate 7 outward and moves the pressure plate 7 away from the flow guiding arc plate 6. During cleaning, the atomizer 11 and the pressure plate 7 move into the fixed cylinder. Since the extended end of the guide arc plate 6 extends above the threaded interface 9, the pressure plate 7 presses against the bottom of the guide arc plate 6, providing a resistance to the guide arc plate 6 and preventing it from rotating. This prevents the filter screen 4 from rotating when the forward and reverse fan 3 rotates, thus filtering dust. During disinfection, rotating the disinfection tank causes the atomizer 11 and the pressure plate 7 to tighten outwards and move the pressure plate 7 away from the guide arc plate 6. This way, the guide arc plate 6 is not under pressure, and the forward and reverse fan 3 blows the guide arc plate 6, causing the filter screen 4 to rotate. This ensures that both sides of the filter screen 4 fully contact the disinfectant during rotation, eliminating the need to disassemble the filter screen 4 for disinfection.
[0023] The shape of the guide arc plate 6 can be set to resemble the structure of a rotating blade in a vertical blade wind turbine. Driven by the wind, the blade can rotate around the central axis. In this invention, the guide arc plate 6 will also rotate under the blowing of the forward and reverse wind turbines, rotating around the central axis of the filter screen 4.
[0024] The inner wall of the fixed cylinder 1 has a rotating groove, and the edge of the filter screen 4 has a protrusion 20. The protrusion 20 is inserted into the rotating groove and is rotatably connected to the rotating groove. A torsion spring 21 is fixedly connected between the protrusion 20 and the rotating groove. When the filter screen 4 is rotated by the forward and reverse fan, the torsion spring 21 stores energy. When the forward and reverse fan 3 stops rotating, the torsion spring 21 releases energy, causing the filter screen 4 to return to its initial state. This allows the guide arc plate 6 to also move to its initial position, so that the pressure plate 7 can press against the surface of the guide arc plate 6 during subsequent use.
[0025] The atomizer 11 includes a piezoelectric ceramic plate 12 and a fixed shell 13. The piezoelectric ceramic plate 12 is disposed inside the fixed shell 13. The fixed shell 13 has an air outlet 14 at its top. The fixed shell 13 has a cotton strip 15 at its bottom, with one end of the cotton strip 15 attached to the piezoelectric ceramic plate 12 and the other end of the cotton strip 15 extending out of the fixed shell 13 and inserted into the disinfection water tank 8. The outer wall of the fixed shell 13 is engaged with the inner wall of the fixed connector 10 by threads. The tampon uses capillary action to draw the disinfectant solution inside the disinfection tank to the bottom of the piezoelectric ceramic plate 12. The piezoelectric ceramic plate 12 converts electrical energy into ultrasonic energy. At room temperature, the ultrasonic energy can atomize water-soluble drugs into tiny droplets of 1µm to 5µm. Using water as a medium, the water-soluble drug solution is sprayed into a mist using ultrasonic directional pressure. The mist is then discharged into the fixed cylinder 1 through the air outlet 14. Under the blowing of the forward and reverse fan 3, the atomized disinfectant solution is sprayed into the vehicle.
[0026] The other end of the fixed cylinder 1 is provided with a handle 17, which has two control switches. Both control switches are electrically connected to the forward and reverse fan 3. The bottom of the handle 17 is also fixedly connected to a vehicle power cord 19. The two control switches are electrically connected to the forward and reverse fan 3 to realize the forward and reverse rotation of the fan, thereby realizing the functions of dust suction or spraying. The piezoelectric ceramic plate 12 of the atomizer 11 is generally connected to a conductive post. Conductive points can also be set on the inner wall of the threaded interface 9. When installing the disinfection water tank 8, the conductive post of the atomizer 11 can be made to contact the conductive point to enable the atomizer 11 to be powered on. There is no need to set a power supply on the atomizer 11. The control switch that controls the reverse rotation of the forward and reverse fan 3 can also control the atomizer 11 to be powered on or off, thereby completing the function of atomizing disinfectant.
[0027] A narrow-mouth suction pipe 5 is detachably and fixedly connected to the suction port. The narrow-mouth suction pipe 5 can be connected to the suction port by means of thread, snap-fit, or plug-in. When not in use, the narrow-mouth suction pipe 5 can be removed without taking up too much space in the vehicle. In this way, the narrow-mouth suction pipe 5 can be inserted into places with small gaps in the vehicle, resulting in better cleaning effect and also enabling targeted disinfection.
[0028] In use, the cleaning cylinder 2 is first installed on the fixed cylinder 1, followed by the disinfection tank 8. When installing the disinfection tank 8, it is first rotated to connect the fixed connector 10 to the threaded interface 9. During the rotation of the disinfection tank 8, the atomizer 11 and the pressure plate 7 continuously move into the fixed cylinder 1. Since the extended end of the guide arc plate 6 extends above the threaded interface 9, the pressure plate 7 presses against the bottom of the guide arc plate 6, preventing the filter screen 4 from moving. Then, the operation can begin. The forward and reverse fan 3 is rotated to the forward direction, drawing air from the suction port into the fixed cylinder 1 and then expelling it through the vent. During the air suction process, dust or grit will be drawn into the fixed cylinder 1 from the suction port. Since the filter screen 4 is fixed, large dust particles will be blocked in the cleaning cylinder 2. The dust inside the cleaning cylinder 2 can be emptied directly afterward. During disinfection, the dust or grit inside the cleaning cylinder 2 is emptied first, and then the disinfection tank 8 is rotated outward slightly, causing the atomizer 11 and the pressure plate 7 to move outward from the fixed cylinder 1. This will move the pressure plate 7 away from the guide arc plate 6, and the guide arc plate 6 will not be under pressure. The forward and reverse fan 3 reverses and blows the guide arc plate 6, causing the filter screen 4 to rotate. At the same time, the atomizer 11 is powered on, atomizing the disinfectant in the disinfection tank 8 and discharging it into the fixed cylinder 1 through the air outlet 14. This ensures that both sides of the filter screen 4 are fully in contact with the disinfectant during the rotation, without the need to disassemble the filter screen 4 for disinfection. This invention can both vacuum and disinfect the vehicle interior, and disinfect the filter screen 4 during the disinfection process, so the filter screen 4 does not need to be disassembled for disinfection afterward.
[0029] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
