1. Field of the Invention
The present invention relates to the field of containers with the effect of nebulizing a solution, and more particularly to an electronic spray cap applicable for all containers available in the market and capable of performing an electronic spray of a constant quantity of the nebulized solution.
2. Description of the Related Art
Containers for containing solutions such as perfume, medicine, or cleaning solution to be nebulized are common in the market. To facilitate the use of the container, a nozzle is generally installed at a bottle mouth of the container for sucking the solution to be nebulized from the container and spraying the nebulized solution out from the nozzle for its use.
Most nozzles of this sort come with a rotary screw thread design or a snap-in design for fixing a nozzle at the bottle mouth of the container, and a leak-proof rubber ring is added and installed to provide a good leak-proof effect. The nozzle of this sort adopts the design of a mechanical press button plus a straw, and the press button is pressed to reduce the interior space of the straw to suck and store the liquid to be nebulized into the straw for use. When the press button is pressed again, the liquid to be nebulized is squeezed out from a nozzle hole to achieve the nebulization effect. Since the nebulization effect is not too good, and the quantity of consumption varies with the pressing force or the pressing depth applied to the press button. Even worse, the nebulization sometimes fails at the final stage of the pressing process and gives rise to the problem of leakage.
However, the quantity of consumption of the solution to be nebulized depends on the designed volume of a liquid storage space inside the nozzle which is restricted by the volume of the nozzle and cannot be expanded too much. Therefore, if the quantity of consumption is insufficient, then it will be necessary for the users to press the press button repeatedly. Even worse, the nebulization may fail, and the nozzle of this sort cannot be used for controlling the quantity of consumption of the solution to be nebulized accurately.
At present, there is an electronic nozzle structure available in the market, but it is limited by the principle of nebulization, so that the electronic nozzle structure cannot be installed to a general container as the mechanical nozzle structure does, and the use of the electronic nozzle structure is inconvenient and the scope of its applicability is limited. Therefore, it is an important subject for related manufacturers to overcome the drawbacks of the conventional mechanical nozzle structure and electronic nozzle structure.
In view of the problems of the prior art, it is a primary objective of the present invention to provide an electronic spray cap combined with an electronic nebulization module and a mechanical power extraction module in a casing, wherein a cap corresponding to different containers available in the market is installed on a side of the casing and the cap is applicable to be installed at a bottle mouth of different containers, so as to broaden the scope of applicability and improve the convenience of use.
Another objective of the present invention is to provide an electronic spray cap having a liquid storage space with a predetermined volume inside the casing for controlling the quantity of consumption accurately. Further, a viewing window is designed on an external wall of the casing and provided for users to observe the volume of the liquid to be nebulized in the liquid storage space.
To achieve the aforementioned objectives, the present invention provides an electronic spray cap installed onto a bottle mouth of a container, and the container contains a solution to be nebulized. The electronic spray cap comprises: a cap, having a set interface with a diameter falling within a range of 5 mm-50 mm, for sealing the bottle mouth; a casing, installed on a side of the cap and connected to the cap, and the casing having a liquid storage space formed therein, and the liquid storage space having a predetermined volume, and an opening formed on the casing being interconnected to the liquid storage space; an nebulization module, installed at the opening and interconnected to the liquid storage space; a power supply, electrically coupled to the nebulization module, for supplying electric power to drive the nebulization module to operate; and a power extraction module, installed in the casing and penetrated through the cap, and an end of the power extraction module extending to the bottom inside the container; when use, the power extraction module sucks the liquid to be nebulized inside the container into the liquid storage space, and then operates the nebulization module to release, nebulize and spray the liquid to be nebulized in the liquid storage space.
In a preferred embodiment, the electronic spray cap of the present invention further comprises a containing space defined in the casing and disposed at a position with a gap from the liquid storage space, and the power supply is disposed in the containing space, and a first switch is installed on a surface of the casing. The power supply comes with a swappable design and has an insert part, and the containing space has an insert hole corresponding to the insert part, and the insert hole is electrically coupled to the first switch and the nebulization module. In another preferred embodiment, the power supply is installed on an external side of the container and electrically coupled to the nebulization module through an appropriate circuit layout.
In a preferred embodiment, the electronic spray cap of the present invention further comprises a viewing window formed on a surface of the casing, connected to the liquid storage space, and provided for a user to observe the volume of the liquid to be nebulized in the liquid storage space, so that the user can control the quantity of consumption of the solution to be nebulized more easily. Alternatively, the power extraction module has an extraction volume corresponding to the liquid to be nebulized, so that a single operation can suck the required quantity of consumption.
In a preferred embodiment, the electronic spray cap of the present invention further comprises a rotary ring covered around the periphery of the casing, and the rotary ring has an opening corresponding to the nebulization module. After the rotary ring is rotated, the opening can be precisely aligned or misaligned with the nebulization module to serve as a first safety switch to prevent the liquid to be nebulized from being released, nebulized and sprayed. In addition, the rotary ring includes an actuating part disposed on inner side of the rotary ring, and the nebulization module has a first switch, and the actuating part is installed at a position corresponding to the first switch. After turning, the first switch is turned on or off. Such arrangement can serves as the first safety switch for the operation.
In addition, the power extraction module comprises a main body, a press portion, an elastic element, a stopper ball and a straw, wherein the main body is installed in the penetrating hole of the casing and passed through the penetrating hole of the cap, and the main body has a flow outlet corresponding to the liquid storage space, and the electric pump is installed in the main body and connected to the straw, and the second switch is electrically coupled to the power supply and the electric pump, and the bottom end of the straw is extended to the bottom inside the container.
