[0035] The passenger car provided in this embodiment has a cleaning device 1 built into the air duct. The cleaning motor 13 drives the cleaning component. At the same time, the slide 121 drives the cleaning mechanism 12 to reciprocate on the slide rail 11. Through a simple structural design, the air duct of the air conditioning system is automatically cleaned without manual assistance, and the degree of automation is high. At the same time, the entire cleaning mechanism 12 is detachable, and the cleaning brush head can be cleaned and replaced.

[0036] To achieve better cleaning results, Figure 2 As shown, in the preferred embodiment of the cleaning mechanism 12, the cleaning component includes a first cleaning component, and the first cleaning component includes a rotating shaft 122 and a first brush head fixed at one end of the rotating shaft 122, wherein the other end of the rotating shaft 122 is connected to the driving shaft of the cleaning motor 13, and when the cleaning mechanism 12 is driven by the slide 121 to reciprocate along the slide rail 11, the cleaning component is driven by the cleaning motor 13 to clean the inner wall of the air duct, and the rotating shaft 122 of the first brush head is axially perpendicular to the moving direction of the cleaning mechanism 12. In this embodiment, the structure of the first brush head is also optimized, preferably, as shown in FIG. Figure 4 As shown, the first brush head is a centrifugal brush head 123, which is a curlable brush 1231 and is fixed to the rotating shaft 122 by a Velcro 1232. It not only has a strong cleaning ability but is also easy to replace.

[0037] The centrifugal brush head 123 is mainly used to clean the upper and lower side walls of the air duct. In order to achieve a cleaning effect without dead corners on the inner wall of the air duct, Figure 5As shown, the preferred cleaning component of this embodiment also includes a second cleaning component, and the second cleaning component includes a turntable and a second brush head 125. The turntable is rotatably arranged on the axial side of the first brush head, and the second brush head 125 is rollably arranged on the inner wall side of the air duct of the turntable facing away from the first brush head. The first brush head and the second brush head 125 jointly form the cleaning end face of the inner wall of the air duct. The cleaning motor 13 is arranged on the slide 121, and its rotating shaft 122 passes through the slide 121 and drives the second cleaning component to rotate relative to the inner wall of the air duct through the coupling 124, and the second cleaning component slides relative to the inner wall of the air duct with the slide 121. Further preferably, the second brush head 125 is detachably mounted on the dust shield 126. In order to optimize the mechanical structure of the cleaning device 1, preferably, the turntable is fixed to the rotating shaft 122 of the cleaning motor 13 through the coupling 124, and the second brush head 125 is arranged on the turntable and the cleaning surface of the second brush head 125 faces the inner wall of the air duct. Not limited to the above solution, in this embodiment, the second brush head 125 can also be preferably spherical, with multiple spherical brush heads 125, all of which are movable and compressibly connected to the turntable. When the turntable rotates to drive the second brush head 125 to clean, the second brush head 125 itself can move to improve the cleaning efficiency and effect. In order to save space, the second brush head 125 is preferably installed in such a way that the second brush head 125 is arranged on the turntable through an elastic member.

[0038] Considering that the first brush head and the second brush head 125 will generate dust during the cleaning process, the diffusion of dust will affect the cleanliness of the cleaning. In this embodiment, preferably, the cleaning component also includes a dust baffle 126, which is arranged between the turntable and the coupling 124, and the turntable is fixed on the dust baffle 126. The dust baffle 126 can prevent the dust generated during the cleaning process of the first brush head and the second brush head 125 from interfering with each other. Further preferably, the dust baffle 126 is semicircular, and the lower edge of the dust baffle 126 extends toward the setting direction of the second brush head 125 to form an extension edge, and the extension edge is enclosed below the lower edge of the dust baffle 126. Not only does it prevent the dust generated by the high-speed rotation of the first and second brush heads 125 from splashing and affecting the cleaning effect during the cleaning process, but the groove formed by the overall extension edge can also collect dust, achieving a better dust blocking effect.

[0039] In order to improve the stability of the cleaning device 1 during operation, it is preferred in this embodiment that the slide rail 11 includes a first slide rail 11 and a second slide rail 11 arranged opposite to each other; the slide 121 includes a first slide rail 121 and a second slide rail 121 arranged opposite to each other, wherein the first slide rail 121 slidably cooperates with the first slide rail 11, and the second slide rail 121 slidably cooperates with the second slide rail 11; the cleaning motor 13 includes a first cleaning motor 13 and a second cleaning motor 13 arranged opposite to each other, the first cleaning motor 13 is arranged on the first slide rail 121, and the second cleaning motor 13 is arranged on the second slide rail 121; the cleaning component includes a first cleaning component, the first cleaning component includes a rotating shaft 122 and a first brush head fixed on the rotating shaft 122, wherein both ends of the rotating shaft 122 are respectively connected to the driving shafts of the first cleaning motor 13 and the second cleaning motor 13, and under the common drive of the first cleaning motor 13 and the second cleaning motor 13, the first brush head rotates around an axial direction perpendicular to the direction of the slide rail 11.

[0040] To further improve the cleaning ability of the device, the cleaning component preferably also includes two second cleaning components, each of which includes a turntable and a second brush head 125, and the second brush head 125 is arranged on a side of the turntable facing away from the first brush head.

[0041] There are many ways to achieve reciprocating motion of the cleaning mechanism 12 on the slide rail 11. In this embodiment, the slide rail 11 is preferably an electric guide rail, and a set of limit switches are provided on the electric guide rail to make the cleaning mechanism 12 reciprocate within a preset range on the guide rail. The electric guide rail is connected to the internal circuit of the bus for power supply, and the limit switch prevents the slide 121 from sliding out of the electric guide rail.

[0042] When receiving the cleaning instruction and starting work, Figure 3 As shown, under the rotation of the cleaning motor 13, the first brush head, i.e., the centrifugal brush head 123, completes the cleaning work on the upper and lower surfaces of the air duct under the action of centrifugal force. At the same time, the second brush head 125 connected to the cleaning motor 13 starts to clean the left and right surfaces of the air duct under the drive of the coupling 124. The slide 121 reciprocates on the electric guide rail, so that the cleaning mechanism 12 performs reciprocating cleaning work in the air duct. The limit switches are set at both ends of the electric guide rail. When the cleaning mechanism 12 runs to the extreme positions on both sides of the guide rail, it touches the limit switches to prevent the cleaning mechanism 12 from moving beyond the guide rail. At the same time, according to the program requirements, the next step of instructions is performed to return to the initial position or stop running, thereby achieving all-round cleaning of the air duct.

[0043] like Figure 6 As shown, preferably, the air conditioning duct 2 system of the vehicle is provided with two side-by-side air conditioning ducts 2, each of which is provided with the above-mentioned cleaning device 1, which is coaxially and synchronously driven. Further preferably, a filtering device is provided at the air inlet of the two side-by-side air conditioning ducts 2, which can effectively prevent the entry of dust and foreign matter, and the prevention and control are combined to improve the cleanliness of the duct.

[0044] In summary, the present invention provides a cleaning device built into the air duct, which includes a slide rail, a cleaning mechanism and a cleaning motor, wherein the slide rail is arranged on the inner wall of the air duct along the air flow direction of the air duct; the cleaning mechanism includes a slide frame slidably matched with the slide rail, a cleaning component fixed on the slide frame, and a cleaning motor driving the cleaning component to perform a cleaning action, so that the cleaning mechanism as a whole can be slidably arranged on the slide rail; the cleaning motor is fixed on the slide frame and is connected to the cleaning component by driving; when the cleaning mechanism is driven by the slide frame to reciprocate along the slide rail, the cleaning component is driven by the cleaning motor to perform a cleaning action on the inner wall of the air duct.
