It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be obtained from these drawings without inventive effort.

For the sake of simplicity, only the parts related to the utility model are schematically shown in the drawings, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this document, "one" means not only "only one" but also a case of "more than one".

According to the utility model provides an embodiment, as shown in fig. 1 and fig. 2, a push type dry powder atomizer, its characterized in that includes:

an inner bottle body 10, wherein an inner cavity 11 for storing dry powder is arranged in the inner bottle body 10, and a user can place dry powder (not shown in the figure) to be sprayed in the inner bottle body 10 according to the requirement; the inner bottle body 10 is provided with a powder spraying pipeline 12, one end of the powder spraying pipeline 12 is arranged at the outer side of the inner bottle body 10, and the other end of the powder spraying pipeline 12 is arranged in the inner cavity 11 of the inner bottle body 10; therefore, the dry powder in the inner cavity 11 can be transmitted to the outside through the powder spraying pipeline 12; in this embodiment, the powder spraying pipe 12 is horizontally disposed at the upper end of the inner bottle body 10.

An outer body 20 in which one end of the inner body 10 is inserted into the outer body 20, and the inner body 10 can be inserted into the outer body 20 from the upper end of the outer body 20, so that the lower end of the inner body 10 is positioned inside the outer body 20; the position of the inner body 10 inside the outer body 20 is adjustable along the axial direction of the outer body 20, i.e., along the vertical direction; that is, the inner body 10 can be slid up and down at the upper end inside the outer body 20.

An adjustable cavity 30 and an inflation cavity 50 are formed between the inner bottle body 10 and the outer bottle body 20, and the inflation cavity 50 is communicated with the outside; specifically, the inner body 10 can abut against the inner wall of the outer body 20, and thus the outer wall of the inner body 10 and the bottom end of the outer body 20 can form a closed space, i.e., the adjustable cavity 30 in this embodiment, specifically, the adjustable cavity 30 is the region formed between the lower side of the inner body 10 and the upper side of the bottom of the outer body 20; a certain gap exists between the sidewall of the inner bottle body 10 and the inner wall of the outer bottle body 20 until the inner bottle body 10 abuts against the inner wall portion of the outer bottle body 20, the gap between the outer wall of the inner bottle body 10 and the inner wall of the outer bottle body 20 is the inflation chamber 50 in this embodiment, and the inflation chamber 50 is communicated with the outside.

When the inner body 10 moves in a direction approaching the outer body 20, that is, when the inner body 10 moves downward, the volume of the adjustable cavity 30 is reduced, the air pressure in the adjustable cavity 30 can be increased, and then the adjustable cavity 30 can be independently communicated with the inner cavity 11, so that the air in the adjustable cavity 30 can be transferred into the inner cavity 11.

When the inner bottle body 10 moves upwards, the volume of the adjustable cavity 30 is increased, the air pressure in the adjustable cavity 30 is reduced, and then the adjustable cavity 30 can be independently communicated with the inflating cavity 50, so that the external air can enter the adjustable cavity 30 through the inflating cavity 50, and the recovery of the air environment in the adjustable cavity 30 is realized.

When a user presses the inner bottle body 10 downwards, the gas in the adjustable cavity 30 can be transmitted to the inner cavity 11, and because the inner cavity 11 is communicated with the outside, in order to keep the inner cavity 11 still in a normal pressure state, the gas flow in the inner cavity 11 can be sprayed outwards along the powder spraying pipeline 12; because the dry powder in the inner cavity 11 can be mixed with the air just introduced to form powder mist, the powder mist can be sprayed outwards along the powder spraying pipeline 12 along with the air flow, and the powder spraying effect is realized.

When the user lifts the inner bottle body 10 upward, the external air can be transmitted to the adjustable cavity 30 through the inflating chamber 50, so that the air can be refilled into the adjustable cavity 30; when the user stops lifting the inner bottle body 10 upwards, the external air is not injected into the adjustable cavity 30 any more, and the adjustable cavity 30 is closed until the user presses the inner bottle body 10 again; when the user continuously presses and lifts the inner bottle body 10, the inner bottle body 10 can continuously spray powder.

In this embodiment, the inner cavity 11 and the adjustable cavity 30 of the inner bottle body 10 are separated by the arrangement of the inner bottle body 10 and the outer bottle body 20, so that the powder spraying action can be simultaneously realized in the air inlet process of the inner cavity 11, the possibility of dry powder remaining in the inner cavity 11 is reduced, and the utilization rate of the dry powder sprayer is increased.
