Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A filter socket for a pneumoperitoneum machine is shown in figures 1-4 and comprises a base 1, a micro switch 2, a liquid level sensing device 3 and a locking mechanism 4, wherein a cavity matched with a filter is arranged in the base 1, the micro switch 2 is arranged at the bottom of the cavity, the micro switch 2 is touched by the bottom of the filter, and when the filter is installed in place, the micro switch 2 at the bottom is triggered to indicate that the filter is installed in place. The liquid level sensing device 3 and the locking mechanism 4 are arranged on the side wall of the base 1, and the liquid accumulation amount in the filter is monitored through the liquid level sensing device 3; and the filter is removably mounted in the cavity by means of a locking mechanism 4.

In one embodiment, as shown in fig. 1-4, two microswitches 2 are provided at intervals, so as to improve the accuracy of in-place detection.

In one embodiment, as shown in fig. 1-4, the liquid level sensing device 3 includes a mounting plate 31 and an infrared sensor 32, the mounting plate 31 is provided with a mounting position, and the mounting position is arranged eccentrically. Preferably, two liquid level sensing devices 3 are arranged, and the filter socket is in a horizontal inclined state when in use; the liquid level sensing devices 3 are respectively arranged below and at the side edges of the base; the infrared sensors have transmission and reception terminals through each infrared sensor. The infrared emission head emits infrared rays, the infrared rays pass through the filter, and the receiving end receives the reflected infrared rays. When no liquid exists in the filter, the reflected intensity is strong, the received reflected intensity is weak when liquid exists in the filter, and whether liquid enters the filter or not is judged according to the intensity difference.

In one embodiment, as shown in fig. 1-4, the locking mechanism 4 includes a locking bracket 41, a locking block 42, a torsion spring 43 and a transmission rod 44, the locking bracket 41 is fixed on the side wall of the base 1, a slot is provided on the base 1 for allowing the locking block to pass through, the locking block 42 is rotatably provided on the locking bracket 41, the transmission rod 44 is slidably provided on the locking bracket 41, and one end of the transmission rod acts on the locking block 42, and the locking block 42 is provided with a locking portion 45 for fastening the filter. When the transmission lever 44 is pressed to apply a pressing force to the locking block 42, the rotating block 42 rotates about its rotation point, so that the locking portion 45 moves into the groove to effect separation from the filter; at the same time, the torsion spring 43 accumulates restoring force. When the transmission lever 44 is released, the locking block 42 is moved into the cavity of the base 1 by the restoring force of the torsion spring 43.

In the above embodiment, as shown in fig. 1-4, the lock block 42 is extended with a lifting portion 46, and the lifting portion 46 is located at the bottom of the base 1.
