DETAILED DESCRIPTION
[0025] The specific embodiments of the present application will be further described in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.
[0026] In the description of the present application, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.
[0027] As Figs. 1-3As shown, a dust removal device for an automobile interior of a preferred embodiment of the present invention includes a dust collector 1, a dust storage container 2, an air inlet and outlet regulator 3 and a blower 4. The dust collector 1 includes a dust collecting bin 11, a dust collecting channel 12 and an air intake grille 13. The air intake grille 13 is arranged on the top of the inner cavity of the dust collecting bin 11, and the air intake grille 13 is located on the floor of the automobile compartment. The dust storage container 2 includes a movable baffle 21, a plug 22, a dust storage bin 23 and a dust storage pipe 24. The outlet at the bottom of the dust collecting bin 11 is connected to the dust storage bin 23 through the dust collecting channel 12, the outlet of the dust collecting channel 12 faces the inlet of the dust storage pipe 24, and the end of the dust storage pipe 24 is a closed end. The movable baffle 21 is rotatably connected to the outlet end face of the dust collecting channel 12. The bottom of the inner cavity of the dust storage bin 23 is connected with a dust exhaust port 25. The plug 22 can In cooperation with the dust exhaust port 25, the inlet and outlet air regulator 3 includes an inlet and outlet air duct 31, a dust filter 32 and a first air door 33. The inlet and outlet air duct 31 includes a dust filter section 311 and an inlet and outlet air section 312. The dust filter 32 is arranged between the dust filter section 311 and the inlet and outlet air section 312. The dust filter section 311 is communicated with the top of the dust storage bin 23. The first air door 33 is arranged at the end of the inlet and outlet air duct 31. The inlet and outlet air section 312 is provided with an air outlet channel 313 and an air inlet channel 314 both of which are communicated with the dust filter section 311. The inlet and outlet air duct 31 is connected to the air inlet 41 of the blower 4 through a connecting pipe 43, and the air outlet 42 of the blower 4 is connected to the connecting pipe 43 through an outlet pipe 44. The air inlet 41 of the blower 4 is provided with a second air door 45, and the air outlet pipe 44 is provided with a third air door 46.
[0028] like Fig. 1 As shown, when the dust collection mode is turned on, the movable baffle 21 is opened, the plug 22 blocks the dust discharge port 25, and the first damper 33 opens the air outlet channel 313 and closes the air inlet channel 314, the second damper 45 is opened and the third damper 46 is closed, so that the air outlet channel 313 is connected to the air inlet of the blower 4; in this way, when the dust collection mode is turned on, the blower 4 drives the dust collector 1 to inhale air so that the air inlet grille 13 absorbs the air in the car interior, so that the dust-containing Dust-laden air is drawn into dust collection bin 11. Sand and dust in dust collection bin 11 are drawn into the dust-laden air and carried along dust collection duct 12 into dust storage 2. Due to the varying masses of air, sand, and dust particles, resulting in varying inertia, the sand and dust with greater inertia enters dust storage duct 24, where all the sand and some dust are separated from the air. The air then enters air inlet and outlet duct 31, where it is filtered by dust filter 32 to ensure clean air. The clean air then enters the air inlet of blower 4 through outlet duct 313 and connecting pipe 43. The direction of the arrow indicates the direction of the air flow.
[0029] like Fig. 2As shown, when the dust removal mode is activated, the movable baffle 21 blocks the outlet of the dust collection channel 12, the plug 22 moves away from the dust discharge port 25, and the dust discharge port 25 is opened. The first damper 33 opens the air inlet channel 314 and closes the air outlet channel 313. The second damper 45 is closed and the third damper 46 is opened, so that the air inlet channel 314 is connected to the air outlet 42 of the blower 4. In this way, when the dust removal mode is activated, the airflow from the air outlet 42 of the blower 4 enters the air inlet channel 314 through the cooperation of the air outlet pipe 44 and the connecting pipe 43. The airflow passes through the dust filter 32 and removes dust attached to the filter paper to prevent the dust filter 32 from clogging. The airflow entrained with dust and sand and dust in the dust container 2 is discharged from the dust discharge port 25. The direction of the arrow indicates the direction of the air flow.
[0030] Exemplarily, the inlet and outlet air ducts 31 are arranged upwardly, the outlet channel 313 is arranged on the upper side of the inlet channel 314, and the dust storage pipe 24 is arranged on the lower side of the dust filter section 311. This ensures that the dust storage pipe 24 is inclined upwardly, so as to ensure that the airflow from the dust collection channel 12 can carry dust into the dust storage pipe 24. The airflow from the dust collection channel 12 forms a partially stable airflow at the top of the dust storage pipe 24. The dust entering the dust storage pipe 24 with the airflow can gather there due to its greater inertia than the air, and does not reach the dust filter 32 with the airflow. Furthermore, a partition is provided in the inlet and outlet section 312 to divide its inner cavity into the outlet channel 313 and the inlet channel 314, and there is a certain distance between the partition and the dust filter 32, so as to ensure that the airflow entering from the inlet channel 314 can sweep the entire surface of the dust filter 32.
[0031] Furthermore, a vent 241 is provided on the connecting partition between the dust storage pipe 24 and the dust filtering section 311, and the vent 241 is located at the upper part of the connecting partition, and the bottom surface of the connecting partition is provided with a baffle 242 for blocking the vent 241, and the baffle 242 is hingedly connected to the connecting partition and the hinge is located on the side close to the dust storage bin 23; in the dust suction mode, the baffle 242 blocks the vent 241 under the suction of the air flow; in the dust removal mode, the baffle 242 droops under the action of gravity and then opens the vent 241, and part of the air flow in the dust filtering section 311 enters the dust storage pipe 24 through the vent 241, thereby blowing away the dust in the dust storage pipe 24 to ensure its internal cleanliness.
[0032] Exemplarily, a connecting rope 26 is connected between the bottom of the movable baffle 21 and the plug 22, the plug 22 is spherical, and the dust outlet 25 matches the shape of the plug 22, and the movable baffle 21 is hingedly connected to the dust collection channel 12 to realize the linkage between the movable baffle 21 and the plug 22. In this way, when the dust suction mode is turned on, the movable baffle 21 opens toward one end of the air inlet of the blower 4 under the action of the pressure difference generated by the flowing air, and the plug 22 simultaneously blocks the dust outlet 25; after the dust suction mode is turned off, the movable baffle 21 is closed under the action of its own gravity and the pulling force of the plug 22, and the plug 22 is separated from the dust outlet 25 and is located below the dust outlet 25, and then the dust outlet 25 is opened.
[0033] Exemplarily, a dust outlet pipe 27 is connected to the bottom of the dust outlet 25. Specifically, the dust outlet pipe 27 includes a vertical section and an outlet section that are interconnected. The vertical section is connected to the dust outlet 25, and the outlet section is tilted downward from the front of the vehicle to the rear of the vehicle. The dust outlet pipe 27 provides a stable airflow environment for the dust outlet 25, reducing interference from external airflow on the discharge of sand, gravel, and dust from the dust outlet 25 after the vehicle is in motion, and preventing external airflow from providing resistance to the exhaust airflow.
[0034] Exemplarily, when the movable baffle 21 is opened, the movable baffle 21 is arranged opposite to the entrance of the dust filter section 311, thereby preventing the dust coming out of the dust collecting channel 12 from directly entering the dust filter 32 in the dust filter section 311, thereby reducing the accumulation of dust on the dust filter 32.
[0035] Exemplarily, the bottom wall of the inner cavity of the dust collecting bin 11 is tilted downward toward the center, and the outlet at the bottom of the dust collecting bin 11 is located at the center of the bottom wall of the inner cavity of the dust collecting bin 11, so that the sand, gravel and dust falling into the dust collecting bin 11 enter the dust collecting channel 12 under the action of gravity.
[0036] Exemplarily, the bottom wall of the inner cavity of the dust storage bin 23 is tilted downward toward the center on all sides, and the outlet at the bottom of the dust storage bin 23 is located at the center of the bottom wall of the inner cavity of the dust storage bin 23. The dust exhaust port 25 is connected below the outlet at the bottom of the dust storage bin 23, so as to ensure that sand, gravel and dust falling into the dust storage bin 23 cannot accumulate and are quickly discharged from the dust exhaust port 25.
[0037] Preferably, the air blower 4 is an air conditioning air blower 4, a plurality of air inlets 41 and a plurality of air outlets 42 are arranged on the air conditioning air blower 4, one air inlet 41 on the air conditioning air blower 4 is connected with the air inlet and outlet pipe 31 through the connecting pipe 43, one air outlet 42 on the air conditioning air blower 4 is connected with the connecting pipe 43 through the air outlet pipe 44, the air conditioning air blower 4 is a power source for air circulation in the vehicle, the air of the air conditioning air blower 4 is derived from the air entering the dust collector 1 or from other places in the vehicle, in the dust collection mode, the clean air sent out by the air outlet channel 313 is sent to the air conditioning air blower 4, and finally to the air conditioning air outlet; in the dust removal mode, the air flow from the air conditioning air blower 4 reversely cleans the dust on the dust filter sheet 32, and finally carries the dust to the dust storage device 2 and discharges the dust together with the sand outside the vehicle. Thus, the air conditioning circulation mode and the pipeline of the existing vehicle can be fully utilized, the structure of the vehicle does not need to be greatly changed, and the development investment is reduced. Preferably, after the vehicle is started, the air conditioning system automatically enters the dust collection mode, and when the passenger considers that the sand and dust need to be discharged outside the vehicle, the dust removal mode is switched.
[0038] In summary, the dust collector 1 is used for preliminarily collecting the sand and dust in the vehicle when the passenger enters the vehicle and the soles of the passenger's shoes rub against the air inlet grille 13, and the sand and dust adhered to the soles of the shoes enters the dust collecting bin 11 under the action of gravity; through the circulation of the dust collection mode and the dust removal mode, the dust and sand just entering the vehicle can be timely cleaned and discharged, the dust can be timely and comprehensively removed, the dust in the vehicle room is ensured to be clean; meanwhile, the dust collection mode and the dust removal mode are switched with each other, so that the air inlet and outlet adjuster can realize that the air flow reversely passes through the dust filter sheet 32, the dust on the dust filter sheet 32 is automatically cleaned to avoid blockage, manual replacement is not needed, a clean and clean vehicle environment is provided for the passenger, and the time or money for cleaning the vehicle is saved; and the motion mechanism basically relies on the air flow and the gravity, electrical use is reduced, the structure is simple and reliable, and the failure is low.
