[0026] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the embodiments and the accompanying drawings.
[0027] See also Figures 2 to 7 The filling port magnetic adapter 200 of the utility model includes a mounting seat 1, a magnetic member 2 and a filter assembly 3. The mounting seat 1 is used to connect with the filling port. The mounting seat 1 is provided with through holes 11 arranged along the up and down directions thereof. The bottom of the mounting seat 1 is provided with a mounting groove 12 with an opening facing downwards. The side wall of the mounting seat 1 is provided with a leak detection hole 13 connected with the mounting groove 12. The magnetic member 2 is arranged in the mounting groove 12. The top of the filter assembly 3 is sealed and connected with the bottom of the mounting seat 1 and closes the opening of the mounting groove 12. Among them, the magnetic member 2 is used to conduct the urea filling gun, and the magnetic member 2 can adopt the existing magnet structure; the filter assembly 3 is used to filter urea impurities. The specific structure and principle of the filter assembly 3 are well known to technicians in the relevant field, so it is not repeated here.
[0028] Since the mounting groove 12 is located at the bottom of the mounting seat 1 and the opening faces downward, after the magnetic member 2 is assembled in the mounting groove 12, the top of the filter assembly 3 is sealed and connected to the bottom of the mounting seat 1, thereby closing the opening of the mounting groove 12. When performing side leakage detection, the gas source can enter the mounting groove 12 through the leak detection hole 13. If leakage occurs, it can be directly determined that there is a problem with the sealing between the top of the filter assembly 3 and the bottom of the mounting seat 1. If there is no leakage, it proves that the sealing between the top of the filter assembly 3 and the bottom of the mounting seat 1 is qualified.
[0029] See also Figure 2 and Figure 3In one embodiment, the top of the filter assembly 3 is welded to the bottom of the mounting seat 1 as a whole.

[0032] Alternatively, if Figure 3 As shown, a plurality of partitions 121 are provided in the installation groove 12 along the circumferential direction of the through hole 11 to form a plurality of positioning grooves 122 inside the installation groove 12, and each positioning groove 122 is provided with a corresponding magnetic part 2. After the air source enters the installation groove 12 through the leak detection hole 13, it can flow into each positioning groove 122 respectively, so as to perform air tightness detection on each assembly position of the magnetic part 2. Among them, the positioning groove 122 can be used for the magnetic part 2 of the conversion formula, but it is not limited thereto.
[0033] See also Figure 2 and Figure 3 The filling port magnetic adapter 200 of the utility model further includes a plug 4, which is detachably disposed in the leak detection hole 13 and is used to block the leak detection hole 13. After the sealing test of the filling port magnetic adapter 200 is qualified, the leak detection hole 13 is blocked with the plug 4. On the one hand, dust can be prevented from entering the installation groove 12 through the leak detection hole 13, thereby avoiding the performance of the magnetic component 2 from being affected.
