Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
Shown in composition graphs 3-4, the utility model provides a kind of resuscitation apparatus suction tude assembly of automobile, comprise connecting tube 10, one end of connecting tube 10 connects the first flexible pipe 20, the other end connects the second flexible pipe 30, first flexible pipe 20 is communicated to the crankcase of resuscitation apparatus and automobile, second flexible pipe 30 is communicated to the turbosupercharger of resuscitation apparatus and automobile, connecting tube 10 is provided with extension mouth 11 near the end of the first flexible pipe 20, the inwall of the interior connecting tube without leave 10 of extension mouth 11 also increases gradually along its axial direction, and at the large end of extension mouth 11, the inwall of connecting tube 10 and outer wall form horn structure 12.Adopt this technological scheme, due to the setting of extension mouth, the internal diameter of connecting tube end is increased, inwall and outer wall form horn structure, after the first flexible pipe is installed on connecting tube, the inwall of the first flexible pipe connects with the inwall of extension mouth, provides guiding for oily vapour enters connecting tube swimmingly from the first flexible pipe, decrease that oily vapour is piled up herein, the phenomenon such as to freeze, reduce the infringement to turbosupercharger.
And further, connecting tube 10 comprises the first diameter section 12 near the first flexible pipe 20, with the Second bobbin diameter section 13 near the second flexible pipe 30, the diameter of the first diameter section 12 is less than the diameter of Second bobbin diameter section 13, according to pneumatic theory, when flow is certain, the area of gas flow through this cross section is less, the flow velocity of gas is larger, therefore, at the inlet end of connecting tube, the setting of the first diameter section is to reduce gas flow area, thus increase the flow velocity of gas, pile up herein and the defect such as to freeze to improve oily vapour, and larger-diameter Second bobbin diameter section, even if oily vapour has slight icing phenomenon, oily vapour passing through in Second bobbin diameter section is not hindered yet, it can not cause the reduction of circulation area owing to freezing and block.
In order to ensure the sealing of connecting tube 10 and the first flexible pipe 20 and the second flexible pipe 30, also the preferred two ends at connecting tube 10 are equipped with seal convexity 14, it is outer to form the sealing configuration of binding type that first flexible pipe 20 and the second flexible pipe 30 are all set in seal convexity 14, in this structure, seal convexity 14 is preferably along the annular protrusion that the circumference of connecting tube 10 extends, because the first flexible pipe and the second flexible pipe have elasticity, after the setting of seal convexity 14 can make two flexible pipes be installed on connecting tube, amount of deformation is larger, combination force is between the two larger, thus realizes sealing reliably.
Further, in order to ensure that connecting tube 10 is consistent with the connecting length of the first flexible pipe 20, second flexible pipe 30, preferably also be provided with positioning convex 15 in the intermediate portion of connecting tube 10, positioning convex 15 is preferably along the annular protrusion that the circumference of connecting tube 10 extends, the side of positioning convex 15 and the end of the first flexible pipe 20 against, the opposite side of positioning convex 15 and the end of the second flexible pipe 30 against, this positioning convex achieves the assembling and positioning with the first flexible pipe and the second flexible pipe, avoids occurring installing defect not in place.
The resuscitation apparatus suction tude assembly that the utility model provides, preferred connecting tube adopts integral structure, integrated injection molding and shaping, and its processing technology is simple, and processing cost is low.
Below be only preferred implementation of the present utility model, it is to be noted, these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model, and, after having read content of the present utility model, relevant technical staff in the field can make various change or amendment to the utility model, and these equivalent form of values fall into the application's appended claims limited range equally.
