Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an intelligent liquid pump for taking purified water in a laboratory comprises a housing 1, an air cavity 2 is formed in the housing 1, a piston 3 is slidably connected in the air cavity 2, a diaphragm 4 is fixedly connected to the left side of the air cavity 2, a buzzer 5 is arranged in the housing 1, a plugging ball 6 is arranged on the side surface of the housing 1, a metal ball 7 is fixedly connected in the plugging ball 6, a receiving box 8 is arranged in the housing 1 and on the left side of the diaphragm 4, a guide rod 15 is inserted and arranged on the right side of the receiving box 8, the side surface of the guide rod 15 is connected with the side surface of the receiving box 8 through a return spring, when the diaphragm 4 does not extrude the baffle 14, the guide rod 15 is driven to automatically reset through the return spring, a baffle 14 is fixedly connected to the right side of the guide rod 15, a push rod 16 is fixedly connected to the left side of the guide rod 15, and a receiving frame 17 is arranged on the left side of the push rod 16, the right side of the bearing frame 17 is provided with a pressure switch connected with the buzzer 5, the left side of the bearing frame 17 is slidably connected with a screw 12, the screw 12 and a one-way meshing plate 18 are in one-way right meshing transmission, the speed of right movement of the screw 12 is delayed, the situation that the ejector rod 16 cannot extrude the bearing frame 17 is avoided, the bearing frame 17 already extrudes the pressure switch, the side surface of the screw 12 is meshed and connected with the one-way meshing plate 18, the left side of the screw 12 is rotatably connected with a bearing plate 11, the side surface of the bearing plate 11 is fixedly connected with a magnetic plate 13, the left side of the bearing plate 11 is provided with a rotating shaft 9, the side surface of the rotating shaft 9 is provided with a throwing rod 10 in an inserting way, the throwing rod 10 is connected with the side surface of the rotating shaft 9 through a tension spring, when the rotating shaft 9 rotates, the throwing rod 10 is thrown out and moves towards the direction far away from the rotating shaft 9, the magnetic separation sheet 19 is arranged on the right side of the rotating shaft 9, a magnetic channel is formed in the side face of the magnetic separation sheet 19, and magnetic force is blocked between the magnetic plate 13 and the metal ball 7 when the liquid pump is normally used.

The working principle is that when the liquid pump is used, a motor is started, a piston 3 reciprocates in an air cavity 2 to enable a diaphragm 4 to expand and contract continuously, liquid is pumped through the movement of a blocking ball 6, a rotating shaft 9 rotates to throw a throwing rod 10 out in normal liquid pumping, the throwing rod 10 moves far away from the rotating shaft 9, a bearing plate 11 is extruded through an arranged roller, the bearing plate 11 drives a screw rod 12 to move rightwards, the screw rod 12 needs to be meshed with a one-way meshing plate 18 for transmission when moving, when the screw rod 12 drives a bearing frame 17 to extrude a pressure sensitive switch on the right side, the diaphragm 4 extrudes a baffle 14, the baffle 14 drives a guide rod 15 to move leftwards, the guide rod 15 extrudes the bearing frame 17 to move leftwards through an ejector rod 16, the bearing frame 17 drives the screw rod 12 to move leftwards and cannot be meshed with the one-way meshing plate 18 for transmission, so the screw rod 12 can move quickly, then get rid of pole 10 and extrude the accepting board 11 once more, screw rod 12 can move right once more, and when diaphragm 4 is lax, just can't cause the extrusion to baffle 14 after the expansion of diaphragm 4 again, consequently accept frame 17 and can move right smoothly and cause the extrusion to the pressure sensitive switch for buzzer 5 can sound automatically and remind the user to change, thereby reached when lax in the inside diaphragm 4 of drawing liquid pump, remind the user to change automatically and avoid influencing the effect of experiment.

After diaphragm 4 relaxes, baffle 14 drives magnetic sheet 13 and removes and makes magnetic sheet 13 reach the magnetic force passageway within range of magnetism piece 19, lead to appearing the magnetic force effect between magnetic sheet 13 and the metal ball 7, so under the effect of magnetic force, metal ball 7 drives blocking ball 6 and removes to being close to magnetic sheet 13 direction, make blocking ball 6 also mouthful shutoff with the business turn over of shell 1, the liquid is taken out in the pause, thereby reached and taken out the liquid when diaphragm 4 relaxes and avoided taking out the liquid measure to appear great difference and cause troublesome effect to the experimenter.

To sum up, this an intelligent drawing liquid pump that pure water was taken for laboratory uses through bee calling organ 5 and pivot 9's cooperation, when using the drawing liquid pump, the starter motor, piston 3 is at the inside reciprocating motion of air cavity 2 for diaphragm 4 is the inflation and contraction constantly, realizes the drawing liquid through shutoff ball 6, when diaphragm 4 appears relaxing, bee calling organ 5 can sound automatically and remind the user to change, thereby reached when relaxing appearing in drawing liquid pump inside diaphragm 4, remind the user to change automatically and avoid influencing the effect of experiment. This an intelligent drawing liquid pump for pure water of laboratory is taken, cooperation through shutoff ball 6 and magnetic sheet 13 is used, after diaphragm 4 relaxes, baffle 14 drives magnetic sheet 13 and removes the magnetic force passageway within range that makes magnetic sheet 13 reach magnetism-isolating piece 19, lead to appearing magnetic action between magnetic sheet 13 and the metal ball 7, the event is under the effect of magnetic force, metal ball 7 drives shutoff ball 6 and removes to being close to magnetic sheet 13 direction, make 6 business turn over also mouthful shutoff with shell 1 of shutoff ball, the liquid pumping of suspending, thereby reached and suspended the liquid pumping and avoided the liquid pumping volume to appear great difference and lead to the fact troublesome effect to the experimenter when diaphragm 4 relaxes. The application range is wider.
