In this way, the external screw thread 140 and the internal screw thread 240 are screwed together, so that the dosing mechanism 200 can be integrally connected with the container body 100, and the movement of the dosing mechanism 200 relative to the container body 100 along the axial direction of the container body 100 can be restricted, thereby improving the reliability and stability of the dosing device 10. In addition, the external thread 140 is disposed on the side of the first positioning portion 130 away from the accommodating cavity 120, and the internal thread 240 is disposed on the side of the second positioning portion 210 close to the bottom wall of the connecting slot 230, so that the first positioning portion 130 and the second positioning portion 210 can not interfere with the internal thread 240 or the external thread 140, and the reliability and convenience of assembling the quantitative distribution device 10 are improved.

The first positioning portion 130 may be a positioning protrusion 131, a positioning post, or other positioning structures. The second positioning portion 210 may be a positioning block 211, a positioning groove 212 or other positioning structures.

Specifically, the elastic restoring member may be elastically deformed in a sliding direction of the sliding member 260, and when the sliding member 260 moves from the first position to the second position, the sliding member 260 presses the elastic restoring member, so that the elastic restoring member is compressively deformed to store elastic potential energy; when the external force acting on the slider 260 is removed, the elastic restoring member restores its shape, so that the slider 260 can be pushed to automatically restore to the first position. Thus, the automatic resetting function of the sliding member 260 can be realized, and the convenience of use can be further improved.

The elastic restoring member may be a compression spring, an elastic sheet or other elastic member. Of course, in other embodiments, the slider 260 may be manually reset without providing a resilient reset member.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

In the present utility model, unless expressly stated or limited otherwise, a first feature "up" or "down" a second feature may be the first and second features in direct contact, or the first and second features in indirect contact via an intervening medium. Moreover, a first feature being "above," "over" and "on" a second feature may be a first feature being directly above or obliquely above the second feature, or simply indicating that the first feature is level higher than the second feature. The first feature being "under", "below" and "beneath" the second feature may be the first feature being directly under or obliquely below the second feature, or simply indicating that the first feature is less level than the second feature.

It will be understood that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

It will be further understood that when interpreting the connection or positional relationship of elements, although not explicitly described, the connection and positional relationship are to be interpreted as including the range of errors that should be within an acceptable range of deviations from the particular values as determined by those skilled in the art. For example, "about," "approximately," or "substantially" may mean within one or more standard deviations, and is not limited herein.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
