Technical Field

The utility model belongs to the technical field of the suction head technique and specifically relates to a prevent wall built-up suction head is related to.

Background

The suction head is made of polypropylene materials of medical institutions and has good hydrophobicity. In some suction heads made of hydrophobic materials, the phenomenon of medium wall hanging can occur when the suction head is used, so that the capacity required by the extracted medium is inconsistent with the actual extraction, the working efficiency is reduced, and the phenomenon of front-back cross contamination can also occur.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to solve the problems that in some suction heads made of hydrophobic materials, the phenomenon of medium wall hanging occurs when the suction heads are used, so that the capacity required by the extracted medium is inconsistent with the actual extraction, the working efficiency is reduced, and the phenomenon of front-back cross contamination also occurs, a wall hanging prevention suction head is provided.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a prevent hanging wall suction head, includes the suction head body, the transfer passage who is used for carrying the medium is offered along its axial to the suction head body, it is provided with the guide block to spiral on transfer passage's the internal perisporium, the one end that is close to medium output direction on the guide block is provided with a plurality of drainage pieces, and is a plurality of drainage piece sets up along the guide block direction, the cross sectional area of drainage piece along medium direction is for increasing gradually.

The utility model discloses a spiral and set up the guide block on transfer passage's internal perisporium to set up a plurality of drainage pieces at one side interval of guide block, play the guide effect to the medium when the transport medium fast at the drainage, when the output medium, guide the medium by the guide block, and make the medium can not the wall built-up.

In order to better prevent the medium from hanging on the wall, the inner peripheral wall of the conveying channel is a conical surface, and the large end of the conical surface is located at the output end of the conveying channel. The inner peripheral wall of the conveying channel is provided with the conical surface, and the conical surface plays a role in guiding the medium, so that the phenomenon of medium wall hanging is effectively prevented.

In order to prevent the medium from being clamped between the drainage block and the guide block, the drainage block is further obliquely arranged between two radial sides of the suction head body and the radial central line of the suction head body. The two side plates of the flow guide block are obliquely arranged, so that the oblique surfaces at the two sides of the oblique arrangement have a guiding effect on the medium.

In order to increase the friction force during contact, a plurality of convex strips are further arranged on the outer peripheral surface of the suction head body. Through set up the sand grip on the suction head body, the sand grip has increased the frictional force when the contact.

The utility model has the advantages that: the utility model discloses prevent wall built-up suction head when using, set up the guide block through circling round on transfer passage's internal perisporium, and set up a plurality of drainage pieces in one side interval of guide block, play the guide effect to the medium when the transport medium soon at the drainage, when the output medium, guide the medium by the guide block, and make the medium can not hang the wall, avoided at some suction heads for using hydrophobic material to make, the phenomenon of medium wall built-up will appear when using, the capacity that will lead to the extraction medium requirement like this is inconsistent with the actual extraction, thereby reduce work efficiency, the problem of front and back cross contamination phenomenon also can appear.
