[0027] In order to clarify the objective, technical solutions and advantages of the present invention, the technical solutions of embodiments of the present invention are described clearly and completely below in conjunction with the drawings accompanying particular embodiments of the present invention. Unless otherwise specified, the terms used herein have common meanings in the art. In the drawings, identical reference numerals denote identical components.
[0028] Figs. 1 and 2 respectively show a 3D view and a top view of a cleaning device 100 according to an embodiment of the present invention; the cleaning device 100 mainly comprises a blower 110, a connecting member 120 and a nozzle 130, wherein the connecting member 120 is arranged between the blower 110 and the nozzle 130, and the blower 110 is connected to the nozzle 130; an airflow that is generated by the blower 110 flows to the nozzle 130 via a fluid passage 121 in the connecting member 120 (as shown in Figs. 3 and 4, arrows indicate the flowing direction of the airflow) , then sprays out from a nozzle outlet 134 of the nozzle 130 to perform a cleaning operation (for example, an airflow sprayed out from the nozzle 130 is used to perform a cleaning operation on a component such as a sensor) . It should be understood that the blower 110 acting as a component that generates an airflow is merely an example; the present invention does not intend to limit the specific type of airflow-generating component, rather any other suitable component that is able to generate a cleaning airflow, or even cleaning liquid, may be chosen (for example, a pump is used to deliver a cleaning liquid to perform a cleaning operation) . When the blower 110 acts as a fluid source, the generated fluid is an airflow; when a pump is the fluid source, the generated fluid is a cleaning liquid. The fluid generated by the fluid source may be used for cleaning a surface of a sensor of a motor vehicle. It should be understood that the present invention does not intend to limit the cleaning target of the cleaning device 100; besides sensors, the cleaning device 100 may also be used for cleaning any other suitable component.
[0029] Under certain specific application conditions, the blower 110 and the nozzle 130 must be positioned in advance, and then the connecting member 120 is further mounted between the blower 110 and the nozzle 130, such that it is difficult to adaptively connect the connecting member 120 between the blower 110 and the nozzle 130, and in particular it is possible for there to be a problem of poor sealing between the connecting member 120 and the nozzle 130 due to fitting tolerance. A decline in sealing performance causes a decline in flow rate of the airflow sprayed out from the cleaning device 110, which negatively affects the cleaning performance of the cleaning device 100, while also possibly causing other harm due to unwanted leakage of cleaning gas or cleaning liquid.
[0030] To mitigate the above defects, the present invention uses a flexible fit between the connecting member 120 and the nozzle 130 (rather than a conventional rigid fit) to enable the connecting member 120 and the nozzle 130 to connect to each other with a better fit, thereby improving the sealing performance between the connecting member 120 and the nozzle 130. Specifically, the connecting member 120 comprises a first portion 126 that is arranged near the blower 110 and a second portion 128 that is arranged near the nozzle 130; the first portion 126 has a connecting member inlet 122 that is connected to the blower 110, and the second portion 128 has a connecting member outlet 124 that is connected to the nozzle 130. The airflow that is generated by the blower 110 flows into the connecting member 120 from the connecting member inlet 122, then flows to the connecting member outlet 124 via the fluid passage 121 between the connecting member inlet 122 and the connecting member outlet 124, and further flows out of the connecting member 120 from the connecting member outlet 124, to flow into the nozzle 130 from a nozzle inlet 132. The first portion 126 is made of a rigid material to provide sufficient strength to the connecting member 120, and the second portion 128 may be made of a flexible material to enable the second portion 128 to flexibly fit with the nozzle inlet 132 of the nozzle 130, and the flexible fit between the second portion 128 and the nozzle inlet 132 is able, by means of deformation of a flexible component, to compensate for the fitting tolerance between the blower 110 and the nozzle 130 when positioned in advance.
[0031] Optionally, the second portion 128 may be made of a flexible material, with the nozzle inlet 132 being made of a rigid material; alternatively, the second portion 128 may be made of a rigid material, with the nozzle inlet 132 being made of a flexible material. In summary, one of the second portion 128 and the nozzle inlet 132 is made of a flexible material, and the other of the second portion 128 and the nozzle inlet 132 is made of a rigid material.
[0032] Optionally, the nozzle inlet 132 may be inserted into the second portion 128; that is, the connecting member 120 may act as a female connector. Alternatively, the second portion 128 may be inserted into the nozzle inlet 132 (as shown in Figs. 5 and 6) ; that is, the connecting member 120 may act as a male connector.
[0033] Preferably, when the second portion 128 is made of a flexible material, the first portion 126 and the second portion 128 may be dual-material injection moulded together. It should be understood that the present invention does not intend to limit the specific connection means of the first portion 126 and the second portion 128; the first portion 126 and the second portion 128 may also be connected together by means of bonding or any other suitable means, and in addition, the first portion 126 and the second portion 128 may also be designed separately and then fitted and connected together.
[0034] Preferably, the connecting member 120 may gradually narrow in a first direction (the vertical direction in Fig. 3) from the connecting member inlet 122 to the connecting member outlet 124, which is able to achieve a faster flowing airflow at the nozzle 130, thereby further improving the cleaning performance of the cleaning device 100.
[0035] Preferably, the connecting member 120 may gradually widen in a second direction (the vertical direction in Fig. 2) , which is perpendicular to the first direction, from the connecting member inlet 122 to the connecting member outlet 124, which is able to enlarge the range of the airflow that is sprayed out from the nozzle outlet 134. thereby enlarging the cleaning range of the cleaning device 100.
[0036] When the second portion is made of a flexible material, preferably, the second portion 128 may be made of a rubber material, and more preferably, the second portion 128 may be made of a rubber material with a Shore hardness of less than 80. It should be understood that the present invention does not intend to limit the specific component materials of the nozzle inlet 132 and / or second portion 128 made of flexible material, rather any other suitable flexible material may be used, for example, foam or any flexible material with a Shore hardness of greater than 40 and less than 80. In the present application, the rigid material may be plastic, for example, but the present application is not limited to this.
[0037] According to another aspect of the present invention, a motor vehicle is proposed, comprising the cleaning device 100 according to any one of the embodiments above.
[0038] Multiple exemplary embodiments of the present invention have been described in detail herein with reference to preferred embodiments. However, those of ordinary skill in the art will understand that, without departing from the concept of the present invention, various alterations and modifications may be made to the specific embodiments described above, and that combinations of the various technical features and structures proposed by the present invention may be made without exceeding the scope of protection of the present invention; the scope of protection of the present invention is defined by the attached claims.
