[0062] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings. These embodiments are only for illustrating this application and are not intended to limit the scope of this utility model.

[0063] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description.

[0064] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0065] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0066] like Figure 1-11 A drip pump device, comprising a protective component and a press-to-spray component;

[0067] The press-spray component is equipped with a spray pipe. The inlet of the spray pipe of the press-spray component is connected to the piston assembly of the drip pump, so that the pressurized fluid flows out through the outlet of the spray pipe of the press-spray component, and a spray port is provided at the outlet.

[0068] A rotary joint and a sliding joint are provided between the protective component and the press-spray component;

[0069] In the initial position, the protective component blocks the nozzle of the press-spray component. The protective component is provided with a limit part I, and the press-spray component is provided with a limit part II. Limit part I and limit part II block the press-spray component, thus locking its pressing stroke.

[0070] After the protective component rotates at a specified angle relative to the press-spray component via the rotary joint, the limiting part I and the limiting part II are misaligned, so that the press-spray component unlocks the pressing stroke via the moving joint, and after the spraying of the press-spray component is started during the pressing stroke, the protective component does not block the spray nozzle of the press-spray component.

[0071] When implementing this application, the key points of implementation are as follows: it can be implemented by combining various types of pumping piston assemblies. The core of this application is to lock and unlock the movement stroke of the press-spray component, thereby achieving the corresponding locking to prevent press-spraying and unlocking to allow press-spraying, as well as controlling the size of the movement stroke of the press-spray component to correspond to the spray dosage.

[0072] And by rotating to unlock, the spray nozzle is further hidden or blocked to prevent contamination;

[0073] The working principle or process of this application is as follows:

[0074] By using rotary joints and prismatic joints, along with multiple limiting structures, a finite number of rotation angles can be achieved, corresponding to the stroke of one prismatic joint. There can be one or more prismatic joints, depending on the groove structure of the prismatic joints; because only the rotation of the protective cover relative to the press-spray component needs to be achieved.

[0075] The pressing and moving of the press-spray component is achieved through the stroke of the sliding pair. This depends on the pressing and moving of the press-spray component relative to the bottle or the target liquid. The press-spray component is used to drive the piston to achieve the purpose of compressing the chamber and expanding the chamber to draw in fluid. The sliding pair can be implemented relative to the protective component or relative to the bottle, which can meet the pumping drive requirements for compression and expansion.

[0076] Specifically, in one embodiment of this application, the movable pair is provided with a stroke limiting part, so that the press spray component performs the corresponding target stroke. By limiting the structure of the movable pair, the corresponding movement stroke is realized to achieve spraying, which is feasible after the cavity is filled with liquid.

[0077] There are two scenarios:

[0078] A single chamber can correspond to more than one injection dose, depending on product requirements. After the chamber is filled with liquid, multiple compression and expansion reciprocating strokes can be used. This is because before activation, the air in the chamber is usually air, and the target fluid being drawn is generally liquid. Therefore, it is necessary to first compress and vent the air, and then fill the chamber with liquid. Atmospheric pressure and the siphon principle can be used to draw in the liquid. At this time, complete compression is not required. If the pressure is sufficient, the chamber can be sealed and unidirectionally drawn in through a one-way valve. When the pressure in the chamber is sufficient to prevent one piston I from descending, the other piston II will press down and disengage from piston I, which can also achieve the purpose of unlocking the injection.

[0079] The injection dose for a single cavity can be directly determined according to product requirements, using the corresponding dose and stroke.

[0080] Specifically, in one embodiment of this application, the protective component is rotated relative to the press-spray component by a specified angle, including at least two specified angles, via a rotary joint;

[0081] The protective components at each specified angle do not obstruct the spray nozzle of the press-to-spray component;

[0082] Each specified angle is equipped with a moving pair to make the pressing stroke of the press-spray component different, so as to execute different target pumping doses;

[0083] To achieve multiple doses of spray, the stroke of the press-and-spray component is controlled at multiple positions, and corresponding spray windows that allow spraying are set.

[0084] Specifically, in one embodiment of this application, the protective component is provided with a limiting part Ⅲ, and the press spray component is provided with a limiting part IX. The pressing stroke of the press spray component is achieved by limiting the limiting part Ⅲ and the limiting part IX. This limiting method is convenient for manufacturing, reliable, and easy to control in terms of accuracy.

[0085] Specifically, in one embodiment of this application, the protective component is provided with a spray window to prevent obstruction of the spray nozzle of the press spray component; the spray window can be implemented by slotting or opening, and its shape is matched with the spatial shape required for spraying.

[0086] Specifically, in one embodiment of this application, the protective component rotates relative to the press-spray component, including clockwise rotation and counterclockwise rotation.

[0087] Specifically, in one embodiment of this application, spray windows are provided on both sides of the limiting part I. This symmetrical arrangement is only symmetrical in position and does not need to be completely mirrored. It can be achieved by matching the dosage and the movement stroke.

[0088] Specifically, in one embodiment of this application, a pressing notch is provided on the protective component to provide space for pressing operation. In order to facilitate pressing the spray component and moving it after pressing, it is necessary to avoid the operator's fingers, so the notch is provided.

[0089] Specifically, in one embodiment of this application, the pressing working surface of the press spray component is provided with anti-slip texture, which is beneficial to the force during the pressing operation;

[0090] Specifically, in one embodiment of this application, the limiting part I is a raised rib on the inner wall, and the limiting part II is a raised injection port.

[0091] Specifically, in one embodiment of this application, the protective component partially surrounds the press-to-spray component, which is suitable for retrofitting existing structures.

[0092] Specifically, in one embodiment of this application, the spray window is arranged along the pressing stroke direction of the press spray component.

[0093] Specifically, in one embodiment of this application, a support member is included, which may be a dropper container connector, a dropper container extension, or a connector for a dropper pump piston assembly.

[0094] Specifically, in one embodiment of this application, the protective component is disposed on the support member and is provided with a rotary joint with the support member, so that the protective component can be rotatably disposed.

[0095] Specifically, in one embodiment of this application, a sliding pair is provided between the press-spray component and the support component, so that the press-spray component has only one degree of freedom of movement relative to the support component.

[0096] Specifically, in one embodiment of this application, a drip pump is provided. The piston assembly of the drip pump includes a piston and a cavity for pumping fluid and compressing the fluid for inputting it into the injection line of the press-to-spray component. The piston assembly includes piston I and piston II. Piston II is disposed in the middle of piston I.

[0097] When piston I and piston II compress the chamber, after piston I reaches the end of the compression stroke, piston II continues to compress so that the chamber is connected to the injection pipe of the press spray component;

[0098] During the expansion stroke, the compressed cavity is in a sealed state. The reset of piston I and piston II creates a negative pressure in the cavity, and the target fluid is drawn into the cavity. A one-way valve is installed at the target fluid inlet of the cavity to allow the target fluid to flow into the cavity in one direction.

[0099] Specifically, in one embodiment of this application, a dropper pump spray bottle includes a container and a suction line, the dropper pump and the container are sealed together, and an atmospheric pressure equalization passage is provided; the dropper pump draws fluid from the container through the suction line.

[0100] For example, a seal is formed between the gasket 3, the snap cap 2, and the snap bottle 4;

[0101] Specifically, in one embodiment of this application, a drip pump includes: a protective cover with anti-opening function, a nozzle, a snap-on cap, a pump core, and a snap-on bottle;

[0102] The design features a childproof cover to prevent accidental opening. The nozzle is locked by the internal structure of the cover, and the medication cannot be delivered normally without rotating the nozzle.

[0103] When the nozzle is rotated to the opening of the protective cover, the nozzle can be pressed to administer the drug.

[0104] Its dosage is controlled by a limiting device on the snap cap, which can achieve precise administration of large doses such as 0.5ml / spray, 1ml / spray, 2ml / spray, and 3ml / spray.

[0105] This application solves the problems of inconvenient quantitative dispensing of commercially available oral liquid medications and the lack of child-protected operation, making medication administration convenient and improving patient compliance;

[0106] This application designs a device that can quantitatively drip and spray medication for oral liquid preparations, which can achieve precise quantitative drug delivery;

[0107] This application features a nozzle protective cover designed to prevent accidental opening by children.

[0108] The protective components include a protective cover 1; the press-to-spray component includes a nozzle 5; and the suction pipe includes a suction tube 12.

[0109] Reset component I9 and reset component II10 can be springs;

[0110] like Figure 1-11 The operation process is as follows:

[0111] 1. Before application, the nozzle of the spray head 5 is in the shielded position of the protective cover 1, and the spray head 5 is locked by the internal structure of the protective cover 1 and cannot be pressed.

[0112] 2. Rotate the protective cover 1, the nozzle turns to the opening of the protective cover 1, and at the same time the height limiting structure fails, the nozzle 5 returns to the pressable state;

[0113] 3. The nozzle 5 drives the main column 6, auxiliary piston 7, and piston 8 downward, overcoming the resistance of the reset part II 10, compressing the cavity space, and the steel ball 11 seals the lower end of the body; until the piston 8 is limited by the body; the main column 6 and auxiliary piston 7 continue to move downward over the resistance of the reset part I 9, the main column 6 and auxiliary piston 7 open, and the gas is released through the channel and nozzle.

[0114] 4. Stop pressing the nozzle 5. Reset parts I 9 and II 10 reset. The main column 6 and the auxiliary piston 7 are closed. During the further reset process, the piston 8 and the auxiliary piston 7 move upward, and a negative pressure is formed in the cavity. The steel ball 11 opens with the lower end of the body, and the liquid medicine is drawn into the cavity as the piston 8 moves upward. After several cycles, the cavity is filled with liquid medicine.

[0115] 5. When piston 8 descends to the bottom, outside gas enters the bottle through the gap between the snap cap 2 and the main column 6, the gap between piston 8 and the body, and the body hole to compensate for the pressure difference;

[0116] 6. Press nozzle 5 again to generate pressure in the chamber, which opens the channel and releases the liquid from the nozzle. When nozzle 5 returns to its original position, the liquid is refilled into the main body chamber for the next application.

[0117] 7. After completing the application, rotate the protective cover 1 to hide the nozzle and lock the nozzle 5 to prevent accidental spraying.

[0118] In summary, this utility model aims to solve the problems of existing drip pumps, which cannot adjust the pump volume, cannot meet different application needs, and have exposed nozzles, making it impossible to lock the pump when pressed, leading to misoperation and safety hazards. By setting a rotary joint, a sliding joint, a limit rotation angle, and a sliding stroke, the pumping dosage can be adjusted and locked.

[0119] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
