Liquid mixing apparatus

Abstract

During the use of a liquid mixing apparatus, a liquid container can be installed onto an adapter. The liquid container drives a lifting assembly to allow a piercing assembly to pierce through the adapter. Once a fluid flows into a flowing passage portion via a fluid inlet, a portion of the fluid is pressurized via a branch passage portion with easy control and further flows into the liquid container to mix with a fragrance material inside the liquid container. The mixed fragrant liquid then flows out of a fluid outlet from the piercing assembly via the return passage portion and the flowing passage portion. With the pressurization design of the branch passage portion, the apparatus allows the increase of dimension to increase the flow rate while maintaining the pressurized liquid, which is convenient to use and facilitated for the control of the mixture amount with greater variation range.

(12) The adapter 4 is arranged on the connecting device and at a location corresponding to the piercing assembly 3. The adapter 4 comprises at least one receiving portion 41, at least one pressing portion 42 formed at a side area of the receiving portion 41. The receiving portion 41 includes at least one liquid container formed thereon; and the pressing portion 42 is configured to exert a pressure onto the liquid container and the lifting assembly 2. The liquid container comprises at least one container housing, a flexible portion formed at a side portion of the container housing and provided for the first piercing member 31 and the second piercing member 32 to selectively pierce therethrough as well as a container pace defined between the container housing and the flexible portion. The container space is stored with at least one fragrance material. In addition, it can be understood that the aforementioned structure is only a possible embodiment of the present invention, and the present invention is not limited to such embodiment only.

(13) As shown in FIG. 1 to FIG. 7, it can be understood that during the installation of the liquid mixing apparatus of the present invention, the connecting device 1 installed on a fluid pipe in order to allow the fluid to enter into the flowing passage portion 113 via the fluid inlet 111 of the connecting main body 11 and to exit via the fluid outlet 112. At this time, since the first through hole 311 and the second through hole 321 are blocked by the connecting cover 12 along with the enhanced sealing effect of the sealing unit 34, the fluid cannot flow to the branch passage portion 114, the return passage portion 115, the first piercing member 31 or the second piercing member 32. In addition, the first piercing member 31 and the second piercing member 32 are received inside the piercing portion 23 of the second abutment member 22 of the lifting assembly 2 in order to prevent accidental injuries of the user etc.

(14) Please refer to FIG. 5 and FIG. 6, when the user wishes to use the liquid mixing apparatus of the present invention, the liquid container 5 can be installed onto the receiving portion 41 of the adapter 4. Then, the pressing portion 42 can be used to exert a pressure onto the container housing 51 in order to allow it to press onto the lifting assembly 2 (the example of threaded fastening method for pressure exertion in this embodiment is used for illustration) in order to allow the second abutment 22 to move and to expose the first piercing member 31 and the second piercing member 32. The first piercing member 31 and the second piercing member 32 are able to naturally pierce through the flexible portion 52 to connect to the container space 53; in addition, the first abutment 21 is caused to move to press against the elastic unit 24 to store elastic energy. Next, the second abutment 22 is able to push the carrier 33 to drive the first piercing member 31 and the second piercing member 32 in order to allow the first through hole 311 to connect with the branch flow space 1141 of the branch passage portion 114. At the same time, the second through hole 321 is able to connect to the return flow space 1151 of the return passage portion 115. In addition, when the fluid switch (such as a faucet etc.) is turned on and the fluid inside the liquid mixing apparatus of the present invention starts to flow toward the direction of the fluid outlet 112, a portion of fluid inside the flowing passage portion 113 is able to flow into the branch flow space 1141 via the branch flow opening 1142 and to further flow toward the first through hole 311 of the first piercing member 31 in order to generate the pressurization effect. The pressurized fluid then flows into the container space 52 via the first piercing member 31 to contact with the fragrance material in order to generate a fragrant fluid. The fragrant fluid is able to flow toward t the flowing passage portion 113 via the second through hole 321, the return flow space 1151 and the return flow opening 1152 of the return passage portion 115, followed by exiting from the fluid outlet 112 for uses. Therefore, the apparatus is able to achieve the effect of deodorization, relaxation and increasing the living pleasure.

(15) Please refer to FIG. 7. When the liquid container is removed from the adapter 4 during replacement after use, the elastic unit 24 then restores to push the first abutment member 21, the second abutment member r22 and the piercing assembly 3 in order to allow the piercing portion 23 to receive the first piercing member 31 and the second piercing member 32 again to prevent accidental injuries of the user. Next, a brand new liquid container 5 can be installed onto the adapter 4; therefore, the liquid mixing apparatus of the present invention is extremely safe and convenient to use.

(16) 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.

(17) 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.
