Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0019] An electronic filter element blockage transmitter, comprising a filter element seat 1, the bottom end of a transmitter 2 is inserted into the top side of the filter element seat 1, the bottom end of the transmitter 2 is connected with the filter element upstream pressure taking hole 4 and the inner cavity of the filter element seat 1 through the filter element downstream pressure taking hole 3, the transmitter 2 is provided with a sensing piston 5, the top side of the sensing piston 5 is provided with a sensing spring 6, the top end of the sensing spring 6 is fixedly connected with a trigger switch 9, and the top side of the trigger switch 9 is fixedly connected with a signal line 12;

[0020] Among them, the electronic filter element blockage transmitter, through the arrangement of the components on the inner side of the transmitter 2, when the inner side of the filter element seat 1 is blocked, the change in the pressure difference between the downstream pressure-taking hole 3 of the filter element and the upstream pressure-taking hole 4 of the filter element drives the sensing piston 5 to move upward, thereby triggering the trigger switch 9 in the switch seat 10, and synchronously outputting an abnormal signal upward through the signal line 12, thereby achieving the effect of sending a blockage signal, with a high degree of automation, solving the problem of low precision and accuracy in the existing manual visual monitoring of the filter element blockage status. Example 2

[0021] The top of the signal line 12 is connected to the controller through a wire; wherein, the setting of the signal line 12 can send out an abnormal signal to the outside, thereby achieving the effect of accurately monitoring the blockage of the filter element seat 1.

[0022] A switch seat 10 located above the induction spring 6 is fixedly installed on the top of the transmitter 2, and a trigger switch 9 is arranged in the switch seat 10; wherein, the switch seat 10 is arranged so as to be able to assemble the trigger switch 9 inside thereof, and the trigger switch 9 is driven by the induction piston 5 below, and then an abnormal signal is sent out using the signal line 12.

[0023] An intermediate joint 7 is arranged between the top of the induction spring 6 and the switch seat 10 , an end joint 8 is fixedly installed on the top side of the intermediate joint 7 , a signal line 12 is arranged on the inner side of the end joint 8 , and a retaining ring 11 is arranged on the inner side of the end joint 8 .

[0024] Preferably, a breathing hole 13 is provided on the outer wall of the transmitter 2 , which is connected to the inner side thereof and is located outside the sensing piston 5 .

[0025] Preferably, sealing rings are provided between the filter element seat 1 and the transmitter 2, between the transmitter 2 and the middle joint 7 on the top side thereof, and between the end joint 8 on the top side.

[0026] The working principle and use process of the utility model are as follows: when the filter element seat 1 is in an unblocked state, the inner side thereof is flowing normally, the pressure difference between the downstream pressure-taking hole 3 of the filter element and the upstream pressure-taking hole 4 of the filter element is small, and the sensing piston 5 does not move under the action of the sensing spring 6. At this time, the trigger switch 9 is not triggered and it is in a disconnected state, and the signal line 12 has no electrical signal output. When the filter element seat 1 is in a blocked state, the gas inside it is blocked, and at the same time, the pressure between the downstream pressure-taking hole 3 of the filter element and the upstream pressure-taking hole 4 of the filter element increases. When the force acting on the sensing piston 5 exceeds the preset force of the sensing spring 6, the sensing piston 5 moves upward, triggering the trigger switch 9, and the switch contacts inside it are closed. At this time, the signal line 12 outputs an electrical signal, which is electrified and automated control with high efficiency and high precision, ensuring the signal triggering effect.
