[0031] In this embodiment, the pre-filter includes a filter bottle 1, a chamber is provided in the filter bottle 1, and a filter element 14 is installed in the chamber to play a filtering role. The filter bottle 1 is the core component of the pre-filter.

[0032] Furthermore, the pre-filter also includes a seal 2, an adapter 3 and a thermometer and pressure gauge 4; the seal 2 is installed at the sewage outlet of the filter bottle 1. During the filtration process, the filter bottle 1 will produce impurities, and the impurities in the filter bottle 1 can be discharged from the sewage outlet by flushing; the adapter 3 is sleeved on the seal 2, and the adapter 3 can be a metal part with high strength and easy processing; the thermometer and pressure gauge 4 can be connected to the adapter 3 through a threaded structure. Specifically, the thermometer and pressure gauge 4 is installed on the side wall of the adapter 3, which is conducive to the arrangement of space; a water flow groove 31 is provided on the inner wall of the adapter 3, and a through hole 21 is provided on the periphery of the seal 2 for the water in the filter bottle 1 to flow to the water flow groove 31.

The water in the filter bottle 1 flows into the water flow groove 31 through the through hole 21, and then flows into the thermometer and pressure gauge 4 through the water flow groove 31. The thermometer can obtain the temperature and pressure signals in the filter bottle 1, and then feed back to the user, so that the use status of the pre-filter can be obtained in time, and the problems such as bottle explosion, rupture, and water leakage caused by temperature and pressure exceeding the normal use range can be avoided. The pre-filter provided by the utility model can timely obtain the temperature and pressure signals in the filter bottle 1 through the setting of the thermometer and pressure gauge 4. Through the cooperation of the sealing member 2 and the adapter, the normal function of the filter bottle 1 can be maintained without affecting the normal installation of the thermometer and pressure gauge 4; the assembly is convenient, the cost is low, and the detection effect is good.

[0035] In some embodiments, the sealing member 2 is provided with a first annular groove 22 and a second annular groove 23 for mounting a sealing ring.

The first annular groove 22 and its sealing ring are used to seal the gap between the filter bottle 1 and the sealing member 2, and the second annular groove 23 and its sealing ring are used to seal the gap between the adapter 3 and the sealing member 2. Because water flows between the through hole 21 and the water flow groove 31, the through hole 21 is disposed between the first annular groove 22 and the second annular groove 23 to improve the sealing effect.

[0036] In some embodiments, an annular clamping platform 24 is provided at the first end of the seal 2, and the first end of the seal 2 is placed in the filter bottle 1 so that the annular clamping platform 24 is clamped with the filter bottle 1. The annular clamping platform 24 can prevent the seal 2 from being removed from the filter bottle 1, thereby ensuring the stability of the connection between the seal 2 and the filter bottle 1.
