The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This utility model provides an automatic ammonia filling device, such as... Figure 1-5 As shown, it includes: a base plate 1, a support plate 2 on the upper end of the base plate 1, and a filling assembly 3 on the upper end of the support plate 2; the filling assembly 3 includes a storage tank 8 on one side of the upper end of the support plate 2, a water inlet pipe 9 connected to one side of the upper end of the storage tank 8, a sealing cap 10 sealed to the water inlet pipe 9, extension plates 4 fixedly connected to the front and rear ends of the support plate 2 respectively, and support seats 5 fixedly connected to the upper ends of the two extension plates 4 on the sides away from each other; electric telescopic rods 6 fixedly connected to the sides of the two support seats 5 on the sides close to each other, and arc-shaped positioning seats 7 fixedly connected to the telescopic ends of the two electric telescopic rods 6 respectively, and the two arc-shaped positioning seats 7 are located at the front and rear ends of the storage tank 8 respectively and are in contact with the front and rear ends of the storage tank 8.
