DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0020] A pressure storage type sprayer, comprising a barrel body 1, a screw-type locking manual supercharging air pump is arranged inside the barrel body 1, the top of the barrel body 1 is provided with a bottle mouth 11, a connecting part 12 is arranged on the bottle mouth 11, a bowl mouth 2 is arranged on the connecting part 12, the bowl mouth 2 is fixedly connected with the bottle mouth 11 through the connecting part 12, a limiting part 3 is arranged on the inner wall of the bowl mouth 2, a convex structure 31 which is in limiting cooperation with the screw-type locking manual supercharging air pump is formed on the limiting part 3, and the limiting part 3 is welded and fixed on the inner wall of the bowl mouth 2. The inner wall of the bowl mouth 2 is recessed outwards to form a sealed installation part 21. The sealed installation part 21 means that there is only one opening formed due to the recess in the recessed part, and the inner wall of the recessed part is a continuous and non-broken surface.
