The covering means that the contact surface between the cap 30 and the outer peripheral surface of the pipe 10 is tightly sealed, and air cannot enter the cap 30 through the contact surface between the cap 30 and the outer peripheral surface of the pipe 10.
Because the blocking member 20 is fixedly arranged on the cover member 30 and the cover member 30 is made of flexible deformable material, the blocking member 20 can be controlled to move relative to the pipeline 10 through the cover member 30 (the cover member 30 can be directly controlled by an operator or can be controlled through other structure relays), in the process, the cover member 30 can be deformed to a certain extent, and when the operator does not apply force to the cover member 30 any more, the cover member 30 can be restored under the action of self elasticity and drives the blocking member 20 to restore;
therefore, the suction valve can realize automatic resetting of the blocking piece 20 without arranging an additional resetting component, the number of parts is further reduced on the premise of ensuring that the suction valve is simple and convenient to operate, and the production and assembly costs are reduced.
In the present application, the cover 30 is provided on the outer peripheral surface of the pipe 10 and is provided with the non-suction inlet 31, and in the non-suction state, the outside air enters the cover 30 through the non-suction inlet 31 and flows along the through groove 12, the suction passage 11 and the suction outlet 111 in this order;
and under the suction state, the cover-shaped piece 30 can deform to close the non-suction inlet 31, at the moment, the outside air can not enter into the cover-shaped piece 30, the cover-shaped piece 30 can realize primary sealing, and meanwhile, the blocking piece 20 can block the through groove 12 to realize secondary sealing, so that the sealing effect is improved through two-section sealing, and air leakage is avoided.

Specifically, the side surface of the blocking member 20, which is close to the suction inlet 112, is tightly attached to the inner wall of the notch 121, and a gap exists between the side surface of the blocking member 20, which is close to the suction outlet 111, and the inner wall of the notch 121; so that in the non-suction state, the stopper 20 blocks the suction inlet 112 and the notch 121 while the suction outlet 111 and the notch 121 communicate through the above gap; in the suction state, the suction through hole 211 moves to be opposite to the suction passage 11 with the movement of the stopper 20, and at this time, the suction through hole 211 communicates with the suction passage 11, that is, the suction inlet 112 communicates with the suction outlet 111.
Through the sliding connection of the blocking piece 20 and the through groove 12, the suction through hole 211 which is matched with the blocking piece 20 is formed, so that the suction valve can be switched between a non-suction state and a suction state only by pressing the blocking piece 20, and the operation is simple.
In some embodiments, the blocking member 20 may also be configured to switch the suction valve between the non-suction state and the suction state by using a design similar to a three-way valve or other corresponding structural design for the blocking member 20 and the through slot 12, and the application is not limited thereto.
Referring to fig. 3 and 4, in some embodiments, the barrier 20 further includes a pressing portion 22; in the suction state, the pressing portion 22 is closely attached to the outer peripheral surface of the pipe 10 to close the notch 121.
Specifically, in the non-suction state, the outside air enters the notch 121 through the gap between the pressing portion 22 and the outer peripheral surface of the duct 10, passes through the suction passage 11, and then flows out from the suction outlet 111; in the suction state, the pressing portion 22 is tightly sealed with the outer peripheral surface of the tube 10 to close the notch 121, so that external air cannot enter the tube 10 through the notch 121, and at this time, blood clots, tissues, secretions and the like in the human body are sucked out along the suction inlet 112, the suction channel 11 and the suction outlet 111 under the negative pressure action at the position of the suction outlet 111.
In some embodiments, the extruding portion 22 is made of a flexible material such as silica gel, rubber, or a rigid material with an outer surface coated with a flexible material, so that when the extruding portion 22 is attached to the outer peripheral surface of the pipe 10, the extruding portion 22 can be deformed to ensure complete attachment to the outer peripheral surface of the pipe 10, so as to increase the sealing performance between the extruding portion 22 and the outer peripheral surface of the pipe 10.
Referring to fig. 3 and 4, in some embodiments, the outer peripheral surface of the pipe 10 is provided with a sleeve-joint portion 13, and the pressing portion 22 is stepped to be respectively attached to the outer peripheral surface of the pipe 10 and the sleeve-joint portion 13 in a suction state.

Since the projection of the blocking portion 212 in the axial direction of the through groove 12 is located within the projection of the plunger 23, that is, the cross-sectional area of the plunger 23 is larger than that of the blocking portion 212, the notch 121 is not blocked when the blocking portion 212 is located at the notch 121, but can be closely attached to the inner wall of the notch 121 when the plunger 23 is inserted into the notch 121, thereby blocking the notch 121.
In some embodiments, the plunger 23 is a flexible material such as silicone, rubber, or a rigid material with an outer surface coated with a flexible material to ensure that the plunger 23 is able to fully conform to the inner wall of the slot 121 to increase the sealing performance between the plunger 23 and the outer circumference of the pipe 10.
