Locking mechanism and joint element will be described in further detail now.The function of locking mechanism can be illustrated best with reference to Fig. 9 to Figure 11.For simplicity, locking mechanism and the joint element at the left side place of fresh air valve as illustrated in the drawing will be only discussed.But the locking mechanism and the joint element that are positioned at the right side place of fresh air valve are identical.
Joint element 41 is the form from outstanding " hook " in the bottom of cover component.This hook comprises from the first outstanding elongated, flexible portion of the bottom of cover plate.Protuberance is formed in the end of this flexible part.This hook also can be described to leg or L shape component.Locking mechanism in present embodiment is the button 4 of the injection molding be arranged in a movable manner in the recess 26 of shell 2 or the form of active element.This button is arranged to move along the axis almost parallel with the air-flow through through-flow openings.Alternatively, this button is arranged to move along the axis vertical with the transverse cross-sectional area of through-flow openings.
In Fig. 9 to Figure 11, can observe, this button comprises two " legs " 42,43 extended from the bottom of button.Each leg is all formed as from the outstanding elongated, flexible protuberance in the bottom of button.A leg 42 is provided with protuberance 44, and protuberance 44 extends outwardly through the little opening 45 in the end wall 22 of through-flow openings.But leg 42 is arranged to flexible, and by bending leg 42, protuberance 44 can be regained from little opening 45.As observed in Fig. 9 to Figure 11, the basal surface of protuberance is formed with inclined surface 46, the EDGE CONTACT of inclined surface 46 and the little opening 45 in end wall 22.Due to the inclined surface of protuberance, when button is pressed downwardly onto in recess, protuberance is forced to regain from little opening, thus leg 42 is bent.When button is released, the hardness of leg 42 makes leg want to turn back to its normal position, thus makes protuberance again extend outwardly through little opening, and thus button moves up again due to inclined surface.
Can also observe from Fig. 9 to Figure 11, the basal surface 47 of joint element is also formed with tilting bottom.Like this, when joint element be pushed down and the basal surface engagement edge of joint element time, or this edge be pushed to left side (orientation according in figure), or this joint element be pushed to right side.Figure 9 illustrates this situation.
Fig. 9 to Figure 11 also show the second leg 43.This second leg is also formed as hook element.The hook element of this second leg allows button to be inserted in recess, and subsequently, the hook element of this second leg engages with slit 48.When button moves up and down in recess, the hook element of the second leg slides up and down in slit 48, but hook element prevent button to move up too far away and drop out recess.This button is also formed with two and guides leg 49 (not shown in Fig. 9 to Figure 11, but illustrating in figures 4 and 5).These two guide leg be arranged perpendicular to the upper surface of button and be arranged in the slit 50 in recess.Slit and guiding leg ensure that button moves up and down in recess.
Generally, the figures illustrate a detailed description of the invention of locking mechanism.But, it should be understood that locking mechanism can perform identical function to those skilled in the art, but there is different forms.Such as, in the present embodiment, leg is guided to have the function guaranteeing that button slides up and down along the path limited by recess.Can say that the second leg 43 has and guarantee that button does not drop out recess and has the function of the tip position limited by recess.First leg 42 has the function that guiding boss passes in and out little opening.Therefore, can say that locking mechanism has three major functions: guiding function, tip position attributive function and protuberance locomotive function.These three functions can be arranged by the physics mode except the physics mode used in the embodiment illustrated.
Fig. 9 shows situation about occurring when cap member moves to its fastening position from its open position.When cap member is pushed downwards in shell, the basal surface 47 of joint element comes in contact with the top of protuberance 44.When cap member is further pushed down, protuberance 44 is pushed further in little opening 45.Joint element 41 also can be promoted a certain amount of according to the intensity difference between the first leg 42 of button and joint element 41 to the right.Be pushed in little opening once protuberance, joint element just can through protuberance always.Joint element is firm through protuberance, and this protuberance will eject (as shown in Figure 10) again because of the elasticity of the first leg 42.Joint element is held in place by protuberance subsequently, and cover plate is held in place in its fastening position.
Figure 11 shows when cover plate is in its fastening position, situation about occurring when button is pushed in recess.In this case, the inclined surface 46 of protuberance 44 is pushed against on the edge of little opening 45.This forces protuberance to be recovered in recess.Once protuberance is regained abundant, joint element just will depart from protuberance, and the bias voltage due to spring is forced outwardly and enters into its open position by cover plate.
Do not drop out shell in order to ensure cover plate, each end of cover plate is provided with two stable elements 60.These stable elements are similarly the form of hook and are hooked in the open position of cover plate on the basal surface 61 of the shoulder 30 of through-flow openings.This basal surface 61 can be observed in Fig. 9 to Figure 11.Owing to there are two stable elements in each end of cover plate, respectively there is a stable element in each corner, and therefore stable element contributes to preventing cover plate from reversing in the opening.
It should be noted that the joint element be arranged on the basal surface of cover plate is arranged on the inner side of through-flow openings, and locking mechanism is arranged on the outside of through-flow openings.Like this, locking mechanism keeps separating with through-flow openings.Interaction between locking mechanism and joint element is occurred by the little opening in end wall.
