The present invention is related to a liquid mixing apparatus convenient to use and facilitated to control the amount of mixture with a greater variation range.
A known fluid type of fragrance device comprises a housing, a container space inside the housing, a channel opening formed on the housing and connected to the container space and a fragrance material received inside the container space. During the use of such known fluid type of fragrance device, the device is installed on the flowing path of the fluid used for washing or flushing, such as the installation on the (shower head) water supply pipe or (toilet) reservoir tank, in order to allow the fluid to contact with the fragrance material for mixing with each other such that fragrance can be introduced into the fluid.
However, through actual experiments, it is found that since there is no special structure provided to increase the fluid pressure before the direct contact between the fluid and the fragrance material, the pressure of the fluid before contacting the fragrance material is close to the pressure of the fluid after contacting the fragrance material. As a result, the flowing pressure of fluid being controlled is insufficient such that interference occurs, leading to the drawback of improper flow of the fluid and, consequently, the drawback of unstable amount of mixture of the fragrance with the flowing fluid. In addition, due to the issue of insufficient pressure of the flowing fluid in the known fluid type of fragrance device, the amount of the flow of the fluid in contact with the fragrance material cannot be controlled and increased. If the amount is increased forcefully, it can lead to more adverse effect of improper fluid flow and unstable mixture amount, or the situation where a portion of the fluid is accumulated at the area of the fragrance material without flowing. Since most of the flowing fluid actually flows out without contacting with the fragrance, the flow rate of the fluid with the use of such known fluid type of fragrance device is limited and cannot be increased effectively.
An objective of the present invention is to facilitate users' use of a fragrance apparatus.
Another objective of the present invention is to allow the arbitrary change of the dimensions of the apparatus during the production of the apparatus in order to control the amount of mixture thereof.
To achieve the aforementioned objectives, the apparatus of the present invention comprises a connecting device having one side formed of a fluid inlet and another side formed of a fluid outlet, and a flowing passage portion is formed inside the connecting device and connected to the fluid inlet and the fluid outlet. In addition, the internal of the connecting device is formed of a branch passage portion connected to the flowing passage portion. The branch passage portion comprises a branch flow space and a branch flow opening connected to the branch flow space and the flowing passage portion. In addition, the internal of the connecting device is formed of a return passage portion connected to the flowing passage portion. In addition, the return passage portion comprises a return flow space and a return flow opening connected to the return flow space and the flowing passage portion. Furthermore, the connecting device includes a lifting assembly moveably arranged thereon, and the lifting assembly includes a piercing assembly moveably arranged thereon. In addition, the piercing assembly comprises a first piercing member selectively connected to the branch passage portion and a second piercing member selectively connected to the return passage portion. The connecting device further includes an adapter arranged at a location corresponding to the piercing assembly.
When the apparatus is not in use, the fluid is able to flow from the fluid inlet to the fluid outlet via the flowing passage portion.
When the apparatus is in use, the user can simply install the liquid container onto the adapter; therefore, the apparatus is facilitated for use. In addition, the liquid container is able to naturally trigger the lifting assembly to allow the first piercing member and the second piercing member of the piercing assembly to protrude out of the lifting assembly and to pierce into the liquid container; thereby allowing the first piercing member to connect to the branch passage portion and the second piercing member to connect to the return passage portion. As a result, the fluid flowing into the flowing passage portion via the fluid inlet can have a portion of the fluid flowing into the branch flow space via the branch flow opening, and it is also able to enter into the liquid container via the first piercing member in order to increase the pressure of the fluid flowing toward the liquid container. Consequently, the flow of the fluid is smooth and is able to mix with the fragrance inside the liquid container; following which it is able to exit from the fluid outlet via the second piercing member, the return flow space, the return flow opening and the flowing passage portion.
When it is not in use or during the replacement of the liquid container, the liquid container can be directly removed from the adapter, and the lifting assembly is able to return to its original position automatically and drive the piercing assembly together in order to allow the first piercing member and the second piercing member to retract back into the lifting assembly as well as sealing the branch passage portion and the return passage portion.
When there I a need for the flow rate of the fluid for mixing, since the structural design of the branch passage portion allows the pressure of the fluid flowing toward the liquid container to increase, the dimensions of the branch passage portion and the return passage portion can be increased under the condition of maintaining the pressurization in order to increase the flow rate. In addition, the range of increase of the dimension is relatively large. With the aforementioned technique, the drawback of the known fluid type of fragrance device can be overcome while achieving the effects of convenience use, facilitated control of amount of mixture and relatively large of variable range.

Furthermore, the structure of the liquid mixing apparatus of the present invention has the pressurization effect capable of generating the physical property of a high-pressure fluid to flow toward the direction of a low-pressure fluid naturally. Consequently, the fluid (high-pressure fluid) at the branch passage portion 114 is able to flow smoothly toward the fluid outlet 112 (low-pressure fluid). Moreover, with the pressurization effect generated by the present invention, the dimensions of the branch passage portion 114 and the return passage portion 115 can be increased in range while maintaining the pressurization effect. When there is a need on the change of the flow rate of the fluid for mixing, the dimensions of the branch passage portion 114 and the return passage portion 115 can be increased depending upon the needs in order to achieve the advantages of controllable amount of mixture for greater variation range.
In view of the above, when the liquid container 5 of the liquid mixing apparatus of the present invention is not installed, the piercing assembly 3 is able to allow the first through hole 311 an the second through hole 321 to be maintained under the sealed state. Consequently, the apparatus of the present invention is still allow the fluid to directly flow therethrough in order to maintain the normal use of the user (for example, the normal opening of shower head for shower, or normal opening of faucet for washing etc.) In addition, once the liquid mixing apparatus of the present invention is installed with the liquid container 5 and after the fluid switch (such as faucet etc.) is closed, since the fluid stops to flow into the branch passage portion 114 and the aforementioned fragrant fluid remains inside the return passage portion 115 without flowing out, the amount of mixture of the fluid with the fragrant material is then stopped, consequently, there is no need to remove the liquid container 5 immediately, and the mixing between the fluid and the fragrance material is stopped naturally such that unnecessary consumption of the fragrance material be reduced. When the fluid switch is turned on again, the flowing fluid is then re-mixed with the fragrance material. Therefore, regardless whether the fluid switch is under the closed state or opened state, the liquid container 5 can always be removed at any time without affecting the use of the fluid switch and the flowing fluid.
