Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1: referring to fig. 1 and 2, a water pump housing is disclosed.
The device comprises a shell body 1, wherein a circulation cavity for liquid circulation is arranged on the shell body 1, and the circulation cavity comprises a water inlet 11, a water outlet 13 and an impeller cavity 12. The water inlet 11 and the water outlet 13 are communicated with the impeller cavity 12. When in use, the impeller of the water pump is positioned in the impeller cavity 12, water enters from the water inlet 11, is pressurized by the impeller cavity 12 and then is discharged from the water outlet 13.
The shell body 1 is also provided with a detection hole 4, and a temperature sensor 2 is arranged in the detection hole 4. The detection hole 4 penetrates the housing body 1 and communicates with the impeller chamber 12. The detection hole 4 comprises a detection hole 42 and a mounting hole 41 which are communicated, the detection hole 42 is communicated with the impeller cavity 12 to accommodate a detection part of the temperature sensor 2, and the mounting hole 41 is used for being connected with the shell 21 of the temperature sensor 2. In the present embodiment, the temperature sensor 2 is a probe-type temperature sensor, but in other embodiments, it may be a temperature sensor of other types.
The probe 22 type temperature sensor 2 includes a probe 22 for detecting a water temperature and a housing 21 connected to the probe 22. In the present embodiment, the probe 22 is located in the detection hole 42, and the housing 21 and the mounting hole 41 can be screwed together. The mounting hole 41 is a stepped hole, the casing 21 is further sleeved with a sealing element 5, and the sealing element 5 is abutted to the casing 21 of the temperature sensor 2 and the hole wall of the mounting hole 41. In the present embodiment, the seal 5 is a seal ring, and the seal ring also abuts against the stepped surface of the mounting hole 41. In other embodiments, the sealing member 5 may also be a raw material tape, and the raw material tape is wound on the thread of the temperature sensor 2, so that when the temperature sensor 2 is screwed with the mounting hole 41, the raw material tape can achieve a better sealing effect.
Still be equipped with the fixed subassembly that is used for fixed temperature sensor 2 on the casing body 1, fixed subassembly includes can dismantle the fixed plate 3 of connection with casing body 1, and the lower surface of fixed plate 3 offsets with the surface of temperature sensor 2's casing 21 and is used for pushing down temperature sensor 2.
