[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5The utility model provides a technical solution: a sealed and drip-proof filling gun, including a filling gun body 1, a connecting head 2, a filling gun barrel 3, a filter plate 4, a movable rod 5, a sealing ring 6, a mounting sleeve 7, a bearing plate 8, a sealing gasket 9, a worm gear 10, a worm 11, a fixing block 12, an exhaust fan 13, a purification plate 14, a limiting strip 15, a battery 16 and a controller 17. The upper end of the filling gun body 1 is equipped with a connecting head 2 and a filling gun barrel 3 and a mounting sleeve 7 arranged above the connecting head 2. The filling gun barrel 3 is threadedly connected to the connecting head 2, and a detachable filter structure is provided on the inner side of the upper end of the filling gun barrel 3, wherein the detachable filter structure includes a filter plate 4 and an movable rod. The movable rod 5, and the filter plate 4 is nested and fits on the inner side of the upper end of the filling barrel 3, and the lower side of the filling barrel 3 is fixedly connected with a sealing ring 6 connected thereto, and an adjustable sealing structure is provided on the outer side of the upper end of the filling barrel 3, wherein the adjustable sealing structure includes a mounting sleeve 7, a supporting plate 8, a sealing gasket 9, a worm gear 10, a worm 11 and a fixing block 12, and the mounting sleeve 7 is threadedly connected to the outside of the filling barrel 3, and a suction purification structure is provided on the inner side of the middle part of the supporting plate 8, wherein the suction purification structure includes an exhaust fan 13, a purification plate 14, a limiting strip 15, a battery 16 and a controller 17, and the exhaust fan 13 is installed on the inner side of the middle part of the supporting plate 8. Specific embodiment 1

[0028] In order to solve the problem that the prior art generally does not have a filtering structure and is not convenient for sealing and preventing dripping of the upper end of the filling barrel 3, this embodiment adopts the following technical solutions, such as Figure 1 、 Figure 3 and Figure 4 First, the filling gun barrel 3 can be threadedly connected to the connector 2 installed on the filling gun body 1 to make it connected, and the sealing ring 6 can be pasted and fixed under the filling gun barrel 3 to ensure the sealing of the connection between the filling gun body 1, the connector 2 and the filling gun barrel 3. Then, the mounting sleeve 7 can be nested and threadedly connected to the outer side of the lower end of the filling gun barrel 3 until the sealing gasket 9 fixed on the lower side of the upper left end of the supporting plate 8 is tightly fitted on the filling gun barrel 3, so that the sealing gasket 9 can block the upper end of the filling gun barrel 3 to seal and prevent dripping;

[0029] like Figure 1 、 Figure 2 and Figure 3Before using the filling gun, the worm 11 that is engaged with the fixed block 12 outside the mounting sleeve 7 can be rotated. Since the right side of the worm 11 is engaged with the worm wheel 10 fixed to the carrier plate 8, the carrier plate 8 is rotatably connected to the inner side of the right upper end of the mounting sleeve 7. Therefore, through the rotation of the worm 11, it is convenient to make the worm wheel 10 drive the carrier plate 8 to rotate under the limit of the mounting sleeve 7, thereby facilitating the disconnection of the fixed sealing gasket 9 on the carrier plate 8 and the filling gun barrel 3, so that the filling gun can be used. The gun performs a filling operation. During the use of the filling gun for filling, a filter plate 4 limited by a movable rod 5 is nested and fitted on the inner side of the upper end of the filling gun barrel 3. The outer end of the movable rod 5 is threadedly connected to the filling gun barrel 3, so it is convenient to set the filter plate 4 so that the filling gun has a filtering structure, and the movable rod 5 can be rotated to disconnect the threaded connection between it and the filling gun body 1, so that the filter plate 4 can be taken out from the filling gun barrel 3 for cleaning to prevent the filter plate 4 from being blocked and affecting the filling. Specific embodiment 2

[0030] In order to solve the problem in the prior art that it is inconvenient to extract and purify the gas emitted by the filling liquid and it is difficult to keep the workers in a good environment, this embodiment adopts the following technical solutions, such as Figure 1 、 Figure 4 and Figure 5 When the filling gun is in use, the battery 16 embedded in the inner side of the right front lower end of the carrier plate 8 can be used to power the controller 17 embedded in the inner side of the right front lower end of the carrier plate 8 and the exhaust fan 13 fixedly installed on the inner side of the middle part of the carrier plate 8, so that the controller 17 controls the operation of the exhaust fan 13. Since the interior of the carrier plate 8 under the exhaust fan 13 is a hollow structure, a purification plate 14 is fitted on the outside of the exhaust fan 13 and is nested with the carrier plate 8. A limiting strip 15 is fitted on the outer side of the middle part of the purification plate 14. The upper end of the limiting strip 15 is connected to the carrier plate 8 for damped rotation. Therefore, through the operation of the exhaust fan 13, the gas emitted by the filling liquid is easily sucked into the carrier plate 8 and discharged after purification by the purification plate 14, thereby making it easier for the operator to be in a good environment. After long-term use, the limiting strip 15 can be rotated to disconnect its fitting limit on the purification plate 14 so that the purification plate 14 can be taken out for replacement. The above electrical components are all existing technologies and will not be described in detail here.
