Description

An accelerated rotation quantitative cover structure

technical field

The invention belongs to the technical field of daily necessities, and relates to an accelerated rotation quantitative cap structure.

Background technique

For liquid or semi-liquid daily consumer products or pharmaceutical products such as laundry detergent, mouthwash, oral medicaments, which are usually contained in containers such as bottles, and poured out for use after filling such products When , there is a need to measure the poured product so that the user can obtain an 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 it. But, the problem of this solution is also obvious, at first, measuring cup is additional additional outside container and container lid, so product parts increase, increase the complexity of user's operation; 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 closing device of its specific structure is set in linkage with the cover. Simply by operating the cover, the 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 prior art, 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. Multiple operations are required for large weighing, and the operation is complicated.

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

Contents of the invention

The purpose of the present invention is to overcome the defects of complex structure, high cost, complicated operation and inability to truly realize continuous weighing in the prior art, and provide an accelerated rotary quantitative meter with simple structure, low cost, simple and labor-saving operation, and capable of continuous weighing. cover structure.

To achieve the above object, the present invention provides the following technical solutions:

An accelerated rotation quantitative cap structure, comprising a lower cap, an upper cap and a sleeve between the upper and lower caps;

The side of the lower cover away from the upper cover is provided with a structure fixedly connected with the bottle body, the side of the lower cover close to the upper cover is provided with a circle of annular groove I, and the side of the lower cover close to the upper cover is located outside the annular groove I and is symmetrically provided with two bosses , gears are installed on the boss, and the part of the lower cover that is located in the annular groove I near the upper cover side has 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 closed plate;

There is an eccentric liquid outlet hole on the upper cover (that is, the center of the liquid outlet hole is not on the symmetrical axis of the upper cover), and the upper cover is provided with a circle of annular groove II near the lower cover side, and the inner wall of the upper cover is provided with an inner ring gear matching the gear;

The sleeve is a hollow cylindrical structure, one end of which is fixed in the annular groove I, and the other end is fixed in the annular groove II. The inner wall of the sleeve is provided with a thread structure I, and the outer wall of the sleeve is provided with a gear matching the outer ring gear;

After the lower cover is fixedly connected with the bottle body, the bottle body is turned over so that the structure of the accelerated rotating quantitative cap faces downward, and the liquid in the bottle enters the sleeve through the liquid inlet hole. At this time, the closing plate blocks the eccentric liquid outlet hole, and the upper cover is rotated , driven by the inner ring gear, the gear and the outer ring gear, the sleeve and the lower cover rotate relatively, and the liquid in the sleeve is extruded downward under the drive of the thread structure I on the inner wall of the sleeve, and at the same time, the upper cover The relative rotation with the lower cover also occurs, 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, because the volume of the sleeve is It is certain, that is, the liquid squeezed out by one rotation is certain. By controlling the number of rotations, the amount of liquid poured out can be controlled, and continuous quantitative pouring can be realized.

Its operation process is as follows:

After connecting the bottle body with the lower cover, turn the bottle body so that the continuous quantitative cap structure is facing down. At this time, the liquid with a certain viscosity in the bottle body will slowly enter the sleeve through the liquid inlet hole. At this time, the upper cover is in a locked state ( That is, the closing plate blocks the eccentric liquid outlet), rotate the upper cover, and it is out of the clamping state (the upper cover rotates, drives the inner ring gear to rotate, and then the gear rotates, and the outer ring gear, which 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 changes, and the eccentric liquid outlet is opened. In addition, due to the existence of the gear rotation ratio, the sleeve will rotate several times for each revolution of the upper cover (2 revolutions or even More), the sleeve internal thread structure I and the inner rod have always produced relatively fast axial relative movement, so that the liquid with a certain viscosity between the sleeve internal thread structure I is extruded through the eccentric liquid outlet, and at the same time due to the thread Structure I is a double-threaded structure. When rotating, it will double the speed of feeding. After the upper cover rotates a circle, the quantification is completed. At this time, there will be obstacles, and a relatively larger force will be used again to restore the upper cover to the locked state. (that is, the closing plate blocks the eccentric liquid outlet hole), the bottle mouth is sealed again, and the liquid will not flow out. If it is necessary to continue to measure, just rotate the upper cover again, because the liquid squeezed out by one rotation is certain. By controlling the number of rotations, the amount of liquid poured out can be controlled, thereby realizing continuous quantitative pouring.

The accelerated rotation quantitative cover structure of the present invention is especially suitable for continuous quantitative weighing of liquids with a certain viscosity such as condensed milk. After the rotation, the axial relative movement between the internal thread structure I of the sleeve and the inner rod extrudes the content in the thread structure I. Since the liquid extruded by one rotation is constant, it can be controlled by controlling the number of rotations. The amount of liquid poured out, and then realized the continuous quantitative weighing of liquid with higher viscosity, although it can not realize the continuous quantitative weighing of liquid with less viscosity such as water at present, but the continuous quantitative cover structure of the present invention can be used as The caps of yogurt bottles provide a brand-new idea for completely solving the problem of continuous quantitative extrusion of liquids.
