[0011] The beneficial effects of a dripping rate monitor disclosed by the utility model are as follows: a proximity switch is connected to an external time relay, which is connected to an alarm, and a time parameter is preset. After a drop of liquid enters from a liquid inlet of a dripping shell, it drops on one end of a swinging piece. Since the middle of the swinging piece is supported by a support block, the drop of liquid affects the balance of the swinging piece. One end of the swinging piece dripping with the drop of liquid swings downward, while the other end naturally tilts upward, triggering the proximity switch. The proximity switch triggers the time relay. When the dripping rate is normal, the time relay will not trigger the alarm. When the dripping rate is too fast or too slow and does not conform to the preset time parameter, the time relay triggers the alarm and sounds an alarm. The monitoring is accurate, human misjudgment is avoided, and an alarm can be issued in time to prevent accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0016] Please refer to Figure 1 and Figure 2 A dripping rate monitor comprises a dripping shell 10, wherein the upper and lower ends of the dripping shell 10 are respectively provided with a liquid inlet 11 and a liquid outlet 12, a monitoring shell 20 is provided on the peripheral wall of the dripping shell 10, and the monitoring shell 20 is open near one end of the dripping shell 10, and a notch 13 is provided on the peripheral wall of the dripping shell 10 corresponding to the position of the monitoring shell 20, and the open end of the monitoring shell 20 is communicated with the interior of the dripping shell 10 through the notch 13, and a swing piece 30 is in the monitoring shell 20, and the swing piece has a symmetrical structure, and a support block 21 is provided at a position corresponding to the middle of the swing piece 30 in the interior of the monitoring shell 20, and the top of the support block 21 is movably connected with the middle of the swing piece 30, and one end of the swing piece 30 extends through the notch 13 to directly below the liquid inlet 11, and a proximity switch 40 is provided at a position corresponding to the other end of the swing piece 30 at the top of the monitoring shell 20, and the proximity switch 40 is controlled to open and close by the swing piece 30.

[0017] In the above scheme, the proximity switch 40 is connected to an external time relay, the time relay is connected to the alarm, and the time parameters are preset. The liquid drops enter from the liquid inlet 11 of the liquid drop shell 10 and drip on one end of the swing piece 30. Since the middle part of the swing piece 30 is supported by the support block 21, the liquid drops affect the balance state of the swing piece 30. One end of the swing piece 30 dripping with liquid swings downward, while the other end naturally tilts upward, triggering the proximity switch 40. The proximity switch 40 triggers the time relay. When the dripping speed is normal, the time relay will not trigger the alarm. When the dripping speed is too fast or too slow and does not meet the preset time parameters, the time relay triggers the alarm and sounds an alarm. The monitoring is accurate, human misjudgment is avoided, and the alarm can be issued in time to prevent accidents.

[0018] Please refer to Figure 2 A protrusion 31 is provided in the middle of the swing piece 30 , and the protrusion 31 is in an inverted U shape. The protrusion 31 covers the top of the supporting block 21 .

[0019] In the above scheme, the swing piece 30 is placed inside the monitoring housing 20 through the cooperation between the protrusion 31 and the support block 21, and remains in a balanced state when not working. When the dripping liquid falls, the balanced state is broken, thereby triggering the proximity switch 40.

[0020] Please refer to Figure 1 The open end of the monitoring housing 20 is sealed and connected to the dripping housing 10. Specifically, the monitoring housing 20 and the dripping housing 10 are integrally formed.

[0021] In the above scheme, the monitoring shell 20 and the drip shell 10 are integrally formed and manufactured, with a stable structure and low cost. At the same time, the monitoring shell 20 and the drip shell 10 maintain a sealed connection, which can meet special usage requirements, such as medical infusion, to prevent external debris from contaminating the drip.

[0022] Please refer to Figure 2 The monitoring housing 20 is made of plastic, and the swinging piece 30 is made of metal.

[0023] In the above solution, the proximity switch 40 triggers the switch by inducing the metal swing piece 30, thereby triggering the time relay.

[0024] Please refer to Figure 1 A card seat 50 is provided at the top of the monitoring housing 20 , and a level bubble 51 is provided on the card seat 50 .

[0025] In the above solution, by observing the level bubble 51, it is possible to confirm whether the monitor is installed in a horizontal position, thereby improving the installation accuracy and convenience.

[0026] The utility model provides a dripping speed monitor, wherein a proximity switch is connected to an external time relay, the time relay is connected to an alarm, and a time parameter is preset. After a drop of liquid enters from a liquid inlet of a liquid dripping shell, it drops on one end of a swinging piece. Since the middle part of the swinging piece is supported by a supporting block, the drop of liquid affects the balance state of the swinging piece, and one end of the swinging piece dripping with the drop of liquid swings downward, while the other end naturally tilts upward to trigger the proximity switch, and the proximity switch triggers the time relay. When the dripping speed is normal, the time relay will not trigger the alarm. When the dripping speed is too fast or too slow and does not meet the preset time parameter, the time relay triggers the alarm to sound an alarm. The monitoring is accurate, artificial misjudgment is avoided, and an alarm can be sounded in time to prevent accidents.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model.
