1. Field of the Invention
The present invention relates to the field of liquid nebulization devices, and more particularly to a rotary nebulization device that switches the supply of a liquid to be nebulized and operates a power supply of the rotary nebulization device by a rotating method.
2. Description of the Related Art
In recent years, various different kinds of nebulization devices are used extensively in the areas of medical healthcare and cosmetics. For example, a liquid such as the medicine or cosmetic solution is nebulized to form gas molecules which are used for maintaining or curing respiratory tract, improving human immunity, softening pores for easy removal of dead skin cells and dirt, and supplementing water quickly to maintain skin smooth, clean and exquisite.
The operation principle of the nebulization devices is to generate vibration energy by a piezoelectric device, and then transmit the vibration energy to a spray orifice plate through a conduction plate to nebulize a liquid passing through the spray orifice plate and spray the nebulized liquid to the outside. Therefore, the liquid including the medicine and cosmetic solutions can be nebulized to form small gaseous molecules that can be absorbed by human body easily. Particularly, it is necessary to control the consumption of a medicine for a specific medical treatment effectively and avoid overdose and underdose that may affect the efficacy of the medical treatment.
To facilitate users to carry and operate the nebulization device, a vast majority of the present nebulization devices are designed with a small volume, and the most common design is in a circular cylindrical shape or a lipstick-like shape and includes a liquid storage space, an nebulization module and a power supply therein, and the liquid to be nebulized is filled into the liquid storage space, and the built-in power supply is provided for driving the nebulization module to release, nebulize and spray the liquid, so that users can carry the device with them and operate the device anytime, anywhere. Since the liquid to be nebulized flows into the liquid storage space gradually by the gravity, therefore there is still a portion of the liquid overflowing or permeating to the outside from the nebulization module after use, and thus not only contaminating the nebulization device, but also contaminating other objects around the nebulization device. Therefore, most nebulization devices available in the market come with a slide bracket covered onto the front side of the nebulization module to avoid the overflow of the liquid to be nebulized when the nebulization device is not in use.
However, the switches of the slide bracket and the nebulization device are installed separately, so that two steps are required for the operation and cause inconvenience to users. Furthermore, the liquid to be nebulized must be packaged into a container in advance to facilitate a direct installation of the container into the liquid storage space. During use, the container is rotated and combined with the nebulization device or operated in an operation habit contrary to the original design of the slide bracket, so that the problem of unsmooth operations often occurs. Obviously, the conventional nebulization device requires improvements.
In view of the problems of the prior art, it is a primary objective of the present invention to provide a rotary nebulization device having an electric connection ring, an nebulization ring and a rotary ring. After the rotary ring is rotated with respect to the electric connection ring and the nebulization ring, a liquid to be nebulized can be interconnected with the nebulization ring and electrically drives the nebulization ring to release, nebulize and spray the liquid to be nebulized, characterized in that a rotation method is used to carry out the operation that fits a user's operation habit and improves the convenience of use.
Another objective of the present invention is to provide a rotary nebulization device having a safety ring for temporarily locking the rotary ring to avoid the overflow caused by an erroneous operation, so as to improve the practicability and the convenience of use of the nebulization device.
To achieve the aforementioned objectives, the present invention provides a rotary nebulization device installed to a container that contains a liquid to be nebulized and has a seal film covered onto an opening of the container, comprising: a main body, having a containing space formed therein and provided for installing a power supply; an electric connection ring, fixed onto a side of the main body and electrically coupled to the power supply, and the electric connection ring having a pair of first contacts disposed thereon; an nebulization ring, fixed to a side of the electric connection ring, and having an nebulization module interconnected to the outside and electrically coupled to the first contact; and a rotary ring, movably mounted onto the nebulization ring, and having a second contact corresponding to the electric connection ring, and an opening portion and a liquid storage slot corresponding to the container, and the opening portion having a film breaking structure corresponding to the seal film, such that when the container is installed to the rotary ring, the film breaking structure scratches or cuts the seal film to let the liquid to be nebulized flow into the liquid storage slot, and the liquid storage slot being normally staggered with the nebulization module to define a closed status, and after the rotary ring is turned, the liquid storage slot is aligned precisely with the nebulization module, and the second contact and the first contact are electrically conducted to define an open status that releases, nebulizes and sprays the liquid to be nebulized.
In a preferred embodiment of the present invention, the rotary nebulization device further comprises a safety ring movably sheathed on the main body, the electric connection ring, the nebulization ring and the rotary ring. In addition, the rotary ring has at least one first position-limiting portion disposed on an external wall of the rotary ring, and the electric connection ring has at least one bump disposed on an external wall of the electric connection ring, and the safety ring has a second position-limiting portion and a stop portion disposed on internal walls of the safety ring corresponding to the first position-limiting portion and the bump respectively for limiting the slide of the safety ring to a position outside the main body, the electric connection ring, the nebulization ring and the rotary ring to prevent the safety ring from falling off. When the safety ring is situated outside the rotary ring, the position-limiting portions can be used for locking the rotary ring to prevent the rotary ring from being rotated by an erroneous operation.
In addition, the rotary nebulization device of the present invention further comprises a water sealing plate installed on a side of the liquid storage slot corresponding to the internal wall of the nebulization ring and tightly coupled to the internal wall of the nebulization ring. Further, the water sealing plate has a circular protruding ring installed on a side corresponding to the nebulization module. The water sealing plate is provided to avoid the occurrence of overflow or leakage of the liquid to be nebulized.
To facilitate the assembling process and limiting the rotation angle of the rotary ring, the nebulization device of the present invention has an elastic snap-in portion disposed on a side proximate to the liquid storage slot, and the internal wall of the nebulization ring has a position-limiting arc slot corresponding to the elastic snap-in portion, and the elastic snap-in portion is movably snapped into the position-limiting arc slot, such that the rotary ring can be rotated with respect to the nebulization ring within a restricted angular range.
To facilitate the assembling process, the electric connection ring has a snap-in portion disposed on a side of the first contact, and the nebulization ring has a snap-in hole corresponding to the snap-in portion, such that the snap-in portion can be snapped into the snap-in hole for the installation.
In a preferred embodiment of the present invention, the rotary nebulization device further comprises a sealing rubber ring installed in the opening portion and disposed at the external periphery of the film breaking structure, and the sealing rubber ring is tightly coupled to an opening of the container.
Wherein, the rotary ring has an anti-slip portion disposed on an external wall of the rotary ring for increasing the friction for the operation and improving the user's operation feel to facilitate the rotation of the rotary ring.
Wherein, the nebulization ring has a first indicating portion disposed on the external wall of the nebulization ring and corresponding to the nebulization module, and the rotary ring has a second indicating portion disposed on the external wall of the rotary ring and corresponding to the first indicating portion.
