[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0027] like Figure 1 - Figure 3 As shown, in one embodiment, a droplet sensor includes:

[0028] The sensor body 1 has a hollow structure inside, and a negative electrode line 4 is connected to its surface. The sensor body 1 can be a four-way aluminum gas distributor block.

[0029] The probe piece 2 is inserted into the interior of the sensor body 1, and one end of the probe piece 2 is connected to the positive line 3;

[0030] The inflow pipeline and the outflow pipeline are respectively connected to the sensor body 1 , and both of them and the inner cavity of the sensor body 1 form a medium flow loop, wherein the inflow pipeline and the outflow pipeline are respectively connected to the sensor body 1 through the pipeline connector 5 .

[0031] Through the above technical solution, when the gas generated by the gas generator enters the sensor body 1 through the pipe joint 5, if the moisture in the gas accumulates in the sensor body 1 to a certain extent, the probe body 24 at the end of the probe part 2 will come into contact with the water, so that the positive line 3, the probe part 2, the negative line 4, and the metal shell of the sensor body 1 form a closed passage. The probe body 24 can generate a feedback signal and transmit it to the outside through the line. The structure of the present application is simple, and compared with the existing complex structure, the cost is lower, and the installation and maintenance are simpler and more convenient.

[0032] Furthermore, the bottom of the sensor body 1 is detachably connected with a maintenance plug 6. Preferably, the maintenance plug 6 and the opening at the bottom of the sensor body 1 can be fixed by a threaded connection, which is more versatile and quicker and more convenient to connect. When impurities appear inside the sensor body 1, the maintenance plug 6 can be opened to clean the impurities inside to ensure that the entire droplet sensor can be used normally. Furthermore, the bottom of the maintenance plug 6 is a hexagon socket bolt, and a sealing ring is provided at the connection position between the maintenance plug 6 and the sensor body 1.

[0033] Furthermore, fixing screws 7 are installed on both sides of the sensor body 1, so that the entire droplet sensor can be stably installed in the use position, and the negative electrode line 4 is fixed to the surface of the sensor body 1 through one of the fixing screws 7. Since the sensor body 1 is metal and is part of the entire closed path, the fixing screw 7 not only fixes the sensor body 1, but also connects the negative electrode line 4 to the sensor body 1.

[0034] Furthermore, the size of the droplet sensor is 40*30*90mm, and the size of the entire droplet sensor is smaller, easier to install, and more suitable for narrow spaces.

[0035] Furthermore, the probe member 2 includes a fixing nut 21 for fixing the positive line 3, a sealing nut 22 is sleeved in the middle of the probe member 2, the sealing nut 22 is connected to the sensor body 1, the outside of the probe member 2 includes a sealing rubber sleeve 23, and the bottom of the probe member 2 protrudes from the bottom of the sealing rubber sleeve 23, the sealing rubber sleeve 23 can be used to protect the probe body 24 to avoid the problem of rust of the probe body 24 caused by too much exposure of the probe body 24, and in order to further avoid the rust of the probe body 24, the material of the probe body 24 can be selected from 304 stainless steel.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
