Description

Technical Field

[0001] The present application relates to the field of vehicle-mounted air purification, and in particular to a vehicle-mounted air disinfection and sterilization device. Background Art

[0002] As people's health awareness increases, the issue of air quality in cars is receiving increasing attention. The closed car environment is prone to breeding bacteria, viruses and odors.

[0003] Traditional in-car air purifiers primarily remove particulate matter and harmful gases through filtration and adsorption, but their effectiveness against bacteria and viruses is limited. In recent years, photocatalytic oxidation and negative ion technologies have been increasingly adopted in vehicles. By installing a filter element made of photocatalytic material into the cylindrical housing of a vehicle purifier, these devices facilitate disinfection and filtration of the in-car air, maintaining cleanliness.

[0004] At present, in the traditional method, a mounting groove is usually opened at the upper end of the shell, and the filter element is fully inserted into the mounting groove to achieve the installation of the filter element. However, when the filter element needs to be replaced after reaching the end of its service life, the user needs to reach into the mounting groove and then pull out the filter element, which makes the replacement of the filter element inconvenient. Summary of the Invention

[0005] In order to facilitate the replacement of the filter element, the present application provides a vehicle-mounted air disinfection and sterilization device.

[0006] The present application provides a vehicle-mounted air disinfection and sterilization device, which adopts the following technical solutions:

[0007] A vehicle-mounted air disinfection and sterilization device includes a shell, an upper cover is installed on the shell, and a purification module, a pumping module and a power supply module are provided in the shell. The pumping module is located in the upper cover of the shell, and the purification module and the power supply module are both located below the upper cover. The purification module includes a filter element and a lifting mechanism, and the filter element and the lifting mechanism are both installed in the shell and located above the power supply module. The lifting mechanism is used to lift the filter element, and the lifting mechanism is also connected to the upper cover. The pumping module is used to suck air outside the shell to the filter element in the shell, and the pumping module is connected to the power supply module.

[0008] By adopting the above technical solution, a purification module, a pumping module, and a power supply module are arranged in the housing, and power is supplied to the pumping module and the purification module via the power supply module. As a result, the pumping module pumps air outside the housing to the filter element in the purification module for purification, and the purified air is then sent out of the housing, thereby achieving the purpose of purifying and disinfecting the air inside the vehicle. When the filter element needs to be replaced, the lifting mechanism is activated by opening the upper cover, so that the lifting mechanism lifts the filter element from the housing, making it convenient for the user to replace the filter element.

[0009] In a specific feasible implementation scheme, the lifting mechanism includes a lifting assembly, a limiting assembly and an unlocking assembly, the lifting assembly includes a lifting rod and a lifting spring, a support rod is provided in the shell, the lifting rod is slidably installed in the support rod, and the lifting rod is located below the filter element, and one end of the lifting rod is used to lift the filter element, the lifting spring is installed in the support rod, and the lifting spring is also connected to the lifting rod, a push rod is installed on the side wall of the lifting rod, and a lifting groove for the push rod to slide is provided on the side wall of the support rod, the limiting assembly is installed on the support rod, and the limiting assembly is also connected to the push rod, the unlocking assembly is installed in the shell, and the limiting assembly and the upper cover are both connected to the unlocking assembly.

[0010] By adopting the above technical solution, when the filter element is installed in the housing, the filter element presses down the lifting rod, causing the lifting rod to compress the lifting spring, and the lifting rod is limited by the limit assembly to keep the lifting spring in a compressed state. When the upper cover is removed, the upper cover drives the unlocking assembly to move, so that the unlocking assembly drives the limit assembly to release the lock on the lifting rod, thereby causing the lifting spring to push the lifting rod to move upward, thereby lifting the filter element, thereby facilitating the removal of the filter element.

[0011] In a specific possible implementation scheme, the lifting trough includes a vertical section and a spiral section, the vertical section extends downward from the upper end of the support rod along the axial direction of the support rod, one end of the spiral section is connected to the lower end of the vertical section, and the other end extends downward in a spiral along the circumferential direction of the support rod.

[0012] By adopting the above technical solution, when the filter element presses the lifting rod downward, the lifting rod drives the push rod to slide along the vertical section and the spiral section of the lifting groove in sequence, so that when the push rod slides to the spiral section, the push rod drives the lifting rod to rotate, thereby facilitating crossing the limit assembly, so that the limit assembly can limit the lifting rod by limiting the push rod.

[0013] In a specific feasible implementation scheme, the limiting assembly includes a limiting ring and a limiting torsion spring, the limiting ring is sleeved on the outside of the support rod, and the limiting ring is located above the lower end of the lifting groove, and a space for storing the push rod is left between the limiting ring and the lower end of the lifting groove, and an unlocking groove for sliding the push rod is opened on the side wall of the limiting ring, the unlocking groove passes through the limiting ring, and the unlocking groove is staggered with the lower end of the lifting groove, the limiting torsion spring is installed in the shell, and the limiting torsion spring is also connected to the limiting ring, and the limiting ring is also connected to the unlocking assembly.

[0014] By adopting the above technical solution, when the lifting rod drives the push rod to slide from the vertical section of the lifting groove to the spiral section, the push rod is also inserted into the unlocking groove of the limit ring, and as the lifting rod continues to move downward, the push rod continues to slide along the spiral section, so that the push rod rotates while also pushing the limit ring to rotate. When the push rod slides to the lower end of the spiral section, the push rod separates from the unlocking groove, so that the limit ring rotates and resets under the drive of the limit torsion spring, so that the unlocking groove and the push rod are staggered, thereby achieving the limitation of the push rod.

[0015] In a specific possible implementation scheme, the unlocking assembly includes a push rod, an unlocking rod, an unlocking spring and a return spring. The push rod is installed in the shell, and one end of the push rod extends upward to the upper end of the shell, and the other end extends downward to the limit ring. The end of the push rod close to the upper end of the shell is used to contact the upper cover. The return spring is installed on the push rod, and the return spring is also connected to the shell. One end of the unlocking rod is installed on the side wall of the push rod, and the other end extends toward the limit ring. A deflection groove for sliding the unlocking rod is provided on the side wall of the limit ring. The unlocking rod drives the limit ring to rotate through the deflection groove. The unlocking spring is installed on the push rod, and the unlocking spring is also connected to the unlocking rod.

[0016] When the filter element is installed and the upper cover is closed, the upper cover presses the push rod downward, causing the push rod to drive the unlocking rod to move downward, so that the unlocking rod is away from one end of the push rod and hits the top wall of the limit ring and rotates in the direction of the push rod, so that the end of the unlocking rod can slide downward along the side wall of the limit ring until the upper cover is completely installed on the shell. The push rod drives the unlocking rod downward to pass the limit ring, so that the unlocking rod is driven by the unlocking spring to rotate downward and reset, and align with the lower end of the deflection groove on the limit ring, so that after the upper cover is removed, the push rod moves upward under the drive of the reset spring, driving the unlocking rod to insert upward into the deflection groove and slide along the deflection groove, thereby driving the limit ring to rotate, so that the lower end of the unlocking groove on the limit ring is aligned with the push rod again, thereby facilitating the push rod to be reinserted into the unlocking groove and upward over the limit ring, thereby facilitating the lifting rod to lift the filter element.

[0017] In a specific possible implementation manner, the purification module further includes a fill light, which is installed in the housing and located below the filter element, and is used to illuminate the filter element.

[0018] By adopting the above technical solution and setting a fill light, a light source of a specific wavelength is provided for filtering and disinfecting the filter element.

[0019] In a specific possible implementation scheme, the suction module includes a suction fan, which is installed in the upper cover and is used to suck air outside the shell into the shell from the purification module and send the air out of the shell from the upper cover.

[0020] By adopting the above technical solution and setting up an exhaust fan, the exhaust fan can be used to conveniently suck air from the lower end of the shell into the filter element for filtering and disinfection, and the purified air is sent out from the upper cover to achieve air circulation purification.

[0021] In a specific possible implementation scheme, a detection module is also provided in the shell, and the detection module includes a formaldehyde detection component and a PM2.5 detection component. The formaldehyde detection component and the PM2.5 detection component are both installed in the shell and located below the purification module, and the formaldehyde detection component and the PM2.5 detection component are both connected to the power supply module, and the formaldehyde detection component and the PM2.5 detection component are both used to detect air quality.

[0022] By adopting the above technical solution and setting up a detection module, it is convenient to monitor the external air quality through the formaldehyde detection element and PM2.5 detection element in the detection module, so that when the ambient air quality is poor, the purification device can be operated in time to purify the air in the car.

[0023] In a specific embodiment, the power supply module includes a battery assembly, which is installed in the housing and is used to supply power to the detection module, the purification module and the pumping module.

[0024] By adopting the above technical solution, a battery assembly is provided to power the detection module, the purification module and the pumping module, thereby conveniently maintaining the normal operation of the purification device.

[0025] In a specific embodiment, an air inlet is provided on the side wall of the shell, and an air outlet is provided on the side wall of the upper cover.

[0026] By adopting the above technical solution, by setting the air inlet, it is convenient for external air to enter the shell from the air inlet for purification, and by setting the air outlet, it is convenient to send the purified air back to the external environment, so as to achieve air circulation.

[0027] In summary, this application has at least one of the following beneficial effects:

The lifting mechanism 7 includes a lifting component 71, a limit component 72 and an unlocking component 73. The lifting component 71 includes a lifting rod 711 and a lifting spring 712. The interior of the support rod 16 is hollow, and a through hole is opened on the top wall of the support plate 13 at the axis of the connecting sleeve 15. The through hole passes through the support plate 13 and passes through the connecting sleeve 15. A lifting rod 711 is slidably mounted in the support rod 16 along the axis of the support rod 16. One end of the lifting rod 711 extends upward into the through hole of the support plate 13. The upper end of the lifting rod 711 is used to abut the bottom wall of the filter element 41. A lifting spring 712 is mounted in the support rod 16. One end of the lifting spring 712 abuts the connection between the support rod 16 and the base 12, and the other end abuts the lower end of the lifting rod 711. The elastic force of the lifting spring 712 is greater than the gravity of the filter element 41. A push rod 713 is fixedly mounted on the side wall of the lifting rod 711. The axis of the push rod 713 is perpendicular to the axis of the lifting rod 711. The push rod 713 passes through the connecting sleeve 15 and the support rod 16. The side wall of the connecting sleeve 15 is provided with an avoidance groove for the push rod 713 to slide. The avoidance groove is arranged in the vertical direction.

When the locking cam 721 is unlocked, the locking cam 721 is unlocked and the locking cam 722 is unlocked, and the winch 720 is locked. When the filter element 41 is at the lower end, the upper end of the lifting rod 711 is pressed into the through hole on the support plate 13 by the filter element 41, and the push rod 713 slides out from the lower end of the unlocking groove 7211 of the limiting ring 721, so that the push rod 713 is separated from the limiting ring 721, so that the limiting ring 721 rotates counterclockwise to reset under the drive of the limiting torsion spring 722, so that the unlocking groove 7211 on the limiting ring 721 is staggered with the push rod 713, so that the bottom wall of the limiting ring 721 limits the push rod 713, thereby keeping the push rod 713 in the current position.

[0050] Reference Figure 4 and Figure 8 The unlocking assembly 73 includes a push rod 731, an unlocking rod 732, an unlocking spring 733, and a return spring 734.

[0052] Reference Figure 2 and Figure 9 When the filter element 41 is installed, the upper cover 2 is installed on the upper end of the shell 1, so that the bottom wall of the upper cover 2 contacts the upper end of the push rod 731 and presses the push rod 731 downward, so that the push rod 731 is gradually pressed into the top wall of the shell 1, so that the push rod 731 drives the unlocking rod 732 to move downward and drives the baffle 735 to compress the return spring 734, so that the unlocking rod 732 contacts the top wall of the limit ring 721, and the unlocking rod 732 rotates in the direction of the push rod 731 and compresses the unlocking spring 733, so that the end of the unlocking rod 732 slides downward along the side wall of the limit ring 721. When the upper end of the push rod 731 is completely pressed into the top wall of the shell 1, the unlocking rod 732 moves downward to the bottom of the limit ring 721. At this time, the unlocking rod 732 rotates and resets in the direction away from the push rod 731 under the action of the unlocking spring 733, so that the end of the unlocking rod 732 away from the push rod 731 moves toward the square of the limit ring 721 and aligns with the lower end of the deflection groove 7212 on the limit ring 721.
