Description

An accelerated rotating quantitative cover structure

technical field

The utility model belongs to the technical field of daily necessities, and relates to an accelerated rotation type quantitative cover structure.

Background technique

For liquid or semi-liquid consumer products such as laundry detergents, mouthwashes, oral medicaments, or medicinal products, it is usually contained in a container such as a bottle, and such product is poured into the container for use At times, there is a need to meter the poured product so that the user can obtain the appropriate usage amount.

It is more common in the market to provide an additional measuring cup, and the user can pour the product into the measuring cup for measurement when using. However, the problems of this solution are also obvious. First of all, the measuring cup is additionally attached to the container and the container cover, so the number of product parts increases, which increases the complexity of the user's operation; moreover, the use of the measuring cup for measuring is very important for the user. The operation requirements are also relatively high, and the product is sometimes easily poured into the hands of the user. For corrosive chemicals, this will affect the safety of the user to a certain extent.

In order to overcome the above defects, those skilled in the art have developed a variety of quantitative cover structures. Patent CN 109649818 A discloses a quantitative cover structure. The closure device of the specific structure is arranged in linkage with the cover. Simply by operating the cover, The communication between the cup-shaped body and the interior of the container can be realized, so that the product in the container can be conveniently injected into the cup-shaped body in a predetermined amount. Although its structure has been greatly simplified compared with the existing technology, its structure is still relatively complicated and its cost is high. At the same time, it can only weigh a certain amount of liquid at a time, and cannot fully realize continuous weighing. Large weighing requires multiple operations, and the operation is complicated.

Therefore, it is of great practical significance to develop an accelerated rotating quantitative cover structure that is simple in structure, simple in operation and labor-saving, and which can realize continuous weighing.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art that the structure is complex, the cost is high, the operation is complicated, and the continuous weighing cannot be truly realized, and an accelerated rotating type which is simple in structure, low in cost, simple in operation and labor-saving and can realize continuous weighing is provided. Quantitative lid structure.

To achieve the above object, the utility model provides the following technical solutions:

An accelerated rotation type quantitative cover structure, comprising a lower cover, an upper cover and a sleeve located between the upper and lower covers;

The lower cover is provided with a structure that is fixedly connected to the bottle body on the side away from the upper cover, the lower cover is provided with a ring-shaped groove I on the side close to the upper cover, and the lower cover is located on the side close to the upper cover. , a gear is installed on the boss, the part of the lower cover that is located in the annular groove I near the upper cover side is provided with a liquid inlet hole, and the middle of the lower cover is connected with an inner rod that is perpendicular to the lower cover and extends in the direction of the upper cover. The top of the inner rod extends radially to form a closing plate;

After the lower cap is fixedly connected to the bottle body, the bottle body is turned over so that the accelerated rotating quantitative cap structure faces downward, and the liquid in the bottle body enters the sleeve through the liquid inlet hole. , Driven by the inner gear, the gear and the outer gear, the sleeve and the lower cover rotate relative to each other, and the liquid in the sleeve is squeezed downward under the drive of the threaded structure I on the inner wall of the sleeve, and at the same time, the upper cover It also rotates relative to the lower cover, and the relative position of the closing plate and the eccentric liquid outlet changes. The closing plate does not block the eccentric liquid outlet, and the liquid in the sleeve is squeezed out from the eccentric liquid outlet. The amount of liquid poured out can be controlled by controlling the number of turns, so as to realize continuous quantitative pouring.

Its operation process is as follows:

After connecting the bottle body and the lower cover, turn the bottle body so that the continuous quantitative cover structure faces downwards. At this time, the liquid with a certain viscosity in the bottle body will slowly enter the sleeve through the liquid inlet hole, and the upper cover is in the stuck state ( That is, the closing plate blocks the eccentric liquid outlet), and the upper cover is rotated to get out of the card position (the upper cover rotates, driving the inner gear to rotate, and then the gear rotates, and the outer ring gear, that is, the sleeve rotates under the drive of the gear), At the same time, the relative position of the closing plate and the eccentric liquid outlet hole changes, and the eccentric liquid outlet hole is opened. In addition, due to the existence of the gear rotation ratio, the sleeve will rotate several times for each turn of the upper cover (2 turns or even more), there has been a relatively fast axial relative movement between the inner thread structure I of the sleeve and the inner rod, so that the liquid with a certain viscosity between the inner thread structure I of the sleeve is extruded through the eccentric liquid outlet hole, and at the same time due to the thread Structure I is a double-ended thread structure. When rotating, the feed will be accelerated twice. After the upper cover rotates for one turn, the quantitative completion is completed. At this time, it will encounter obstacles. Use a relatively larger force again to restore the upper cover to the card position. (that is, the eccentric liquid outlet hole is blocked by the closing plate), the bottle mouth is sealed again, and the liquid will not flow out. If it is necessary to continue to quantify, the upper cover can be rotated again. The amount of liquid poured out can be controlled by controlling the number of rotations, thereby realizing continuous quantitative pouring.

The accelerated rotating quantitative cover structure of the utility model is particularly suitable for continuously quantitatively weighing liquids with a certain viscosity, such as condensed milk, etc. After the sleeve is rotated, the axial relative motion generated between the inner thread structure I and the inner rod of the sleeve extrudes the content in the thread structure I. Since the liquid extruded by one rotation is constant, by controlling the number of rotations, that is, The amount of liquid poured out can be controlled, thereby realizing continuous quantitative weighing of liquids with relatively high viscosity. The structure is used as the cover of yogurt bottles, etc., which provides a new idea for completely solving the problem of continuous quantitative extrusion of liquid.
