Abstract
The utility model discloses a liquid drug accommodating chamber structure for a micro atomization device, comprising a main body and an atomization component, wherein the main body is provided with a sprayer, the sprayer is internally provided with a liquid drug container chamber, the front end of the liquid drug container chamber is connected with a spray orifice via the atomization component, the liquid drug container chamber is internally provided with an arc wall surface or a curve wall surface, and the bottom end of the arc wall surface or the curve wall surface is parallel to or slightly lower than the spray orifice. When a liquid drug flows to the spray orifice of the atomization component and then enters the oral cavity of a user, the effect of reducing drug residue is realized, drug liquid is further saved, and waste is reduced because the bottom of the arc wall surface or the curve wall surface is very close to the spray orifice of the atomization component. The liquid drug accommodating chamber structure for the micro atomization device can be widely applied in medical treatment.

Accompanying drawing 1 is the liquid pharmaceutical accommodation chamber section side-looking structural representation of known micro-atomizing device; the liquid pharmaceutical accommodation chamber 1 of this micro-atomizing device is a square cavity 11; at this square cavity 11 spray orifice 13 is set again; and spray orifice 13 is near square cavity bottom 12; spray orifice 13 is the outlet of supply of chemical; the outlet of this medicinal liquid offers the input of atomizing element medicinal liquid; above-mentioned existing technology; because bottom 12 is the plane; usually have between the bottom 12 and spray orifice 13 that the part medicinal liquid remains in square cavities 11, cause the waste of medicinal liquid.
The utility model content
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of liquid pharmaceutical accommodation chamber structure that can reduce the micro-atomizing device of liquid waste.
The technical scheme that its technical problem that solves this utility model adopts is:
The liquid pharmaceutical accommodation chamber structure of micro-atomizing device, comprise main body and atomizing element, described main body is provided with shower nozzle, be provided with the liquid pharmaceutical vessel in the described shower nozzle, described liquid pharmaceutical vessel front end is connected with spray orifice by the atomizing element, be provided with curved wall or curve wall in the described liquid pharmaceutical vessel, the least significant end of described curved wall or curve wall is equal with spray orifice or more lower slightly than spray orifice.
Be further used as preferred embodiment, also be provided with button on the described main body.
Be further used as preferred embodiment, described atomizing element is a piezoelectric element.
Be further used as preferred embodiment, described piezoelectric element is a ceramic sheet.
The beneficial effects of the utility model are: this utility model flows to atomizing element spray orifice when entering in the user oral cavity when liquid pharmaceutical, because the curved wall of this liquid pharmaceutical accommodation chamber or curve wall bottom are near atomizing element spray orifice, therefore has the residual effect of the medicinal liquid of minimizing, further save medicinal liquid, cut the waste.

The specific embodiment
With reference to Fig. 4, the liquid pharmaceutical accommodation chamber structure of micro-atomizing device, comprise main body 4 and atomizing element 35, described main body 4 is provided with shower nozzle 3, be provided with liquid pharmaceutical vessel 31 in the described shower nozzle 3, described liquid pharmaceutical vessel 31 front ends are connected with spray orifice 34 by atomizing element 35, are provided with curved wall 32 or curve wall in the described liquid pharmaceutical vessel 31, and the least significant end of described curved wall 32 or curve wall is equal or more lower slightly than spray orifice 34 with spray orifice 34.
Be further used as preferred embodiment, also be provided with button 41 on the described main body 4.
Be further used as preferred embodiment, described atomizing element 35 is a piezoelectric element.
Be further used as preferred embodiment, described piezoelectric element is a ceramic sheet.
See also shown in Figure 4ly, be the shower nozzle and the agent structure sketch map of this utility model micro-atomizing device.Wherein, micro-atomizing device includes shower nozzle 3 and 4 two parts of main body, include liquid pharmaceutical accommodation chamber 31, curved wall 32, liquid pharmaceutical 33 and spray orifice 34 in this shower nozzle 3, this spray orifice 34 is connected with atomizing element 35, and main body 4 utilizes button 41 to control the action that shower nozzle 3 produces little atomizing, this atomizing element 35 is to be made of piezoelectric element, and this piezoelectric element is that a ceramic sheet constitutes.
See also Fig. 2 and Fig. 3; be the liquid pharmaceutical accommodation chamber front sectional structure sketch map of this utility model micro-atomizing device and the liquid pharmaceutical accommodation chamber section side-looking structure chart of micro-atomizing device; the liquid pharmaceutical accommodation chamber 2 that wherein is arranged at shower nozzle inside has a cavity 21; and liquid pharmaceutical accommodation chamber 2 is from the extreme higher position to the extreme lower position; be curved wall 22 or curve wall (not shown) structure; because curved wall 22 or curved wall mask have the function near vertical water conservancy diversion liquid pharmaceutical; so this utility model is specifically designed to those structures; reach the shortcoming of improving known structure; and this curve wall can be rule or irregular, all in protection domain of the present utility model.
According to said structure, when liquid pharmaceutical flow to atomizing element (as shown in Figure 4) spray orifice 23 and enters the user oral cavity, because the bottom of this liquid pharmaceutical accommodation chamber 2 is very near this atomizing element spray orifice 23, even but design bottom and spray orifice 23 be co-altitude, therefore has and can reduce the residual effect of medicinal liquid.
More than be that preferable enforcement of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of this utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
