The present invention relates to a mixing device, and more particularly, to a mixing device for individual hydration unit, two different liquids can be adjustably mixed before served by the user.
A conventional mixing device for individual hydration unit generally includes a bag with two storage chambers in which two different liquids are received, a first hose and a second hose are connected with the two chambers and communicate with a “Y” shaped connector which is connected to a third hose. The first and second hoses each have a recessed regulator so as to regulate the volume through the hoses. The drawback is that the adjustment is complicated and not easy to control. Another conventional mixing device for individual hydration unit generally includes a bag with a box, and a mixing unit. There are two inlets defined in the top of the mixing unit, wherein a first inlet for introducing water to the bag, a second inlet for introducing material to the box. An outlet is connected with a mouthpiece. The water is mixed with the material in a space at least 5 ml and the mixture is served via the mouthpiece. By the specific arrangement, a desired mixture can be obtained and the operation is easy for the users. However, the user can only control the volume of the material rather than the volume of the water, so that the users cannot have the desired ratio of the mixture of the material and the water.
The present invention intends to provide a mixing device which can mix different liquids with multiple options of mixing ratio.
The present invention relates to an individual hydration unit and comprises a bag having a first chamber and a second chamber defined therein. The first chamber has a first outlet connected thereto which is connected to a first hose, and the second chamber has a second outlet connected thereto which is connected to a second hose. A regulator is connected to the first and second hoses and a third hose is connected to the regulator and located in opposite to the first and second hoses. A mouthpiece is connected to a distal end of the third hose. The regulator has a cylindrical body which has a first passage, a second passage and a third passage. A restriction ring is connected to an end of the body and an index is marked on an outside of the body. An operation rod is rotatably inserted in the body and a knob is connected to an end of the operation rod. A marker extends inward and radially from the knob and has a hook portion which is engaged with the restriction ring. Two first paths, two second paths, a third path and two fourth paths are defined through the operation rod. The first, second, third and fourth paths are in communication with each other. A connection assembly is attached to the body and includes a connection piece and a connection member, wherein the connection piece has a rectangular protrusion extending from a mediate portion thereof. An adjustment slit is defined in the protrusion. The connection member has a rectangular engaging hole which has an adjustment slot. The protrusion is engaged with the engaging hole.
An alternative embodiment of the present invention provides the operation rod that includes first slot and a second slot defined therein, wherein the first and second slots are wedge-shaped slots and orientated in opposite directions. A third slot is defined in the operation rod and located in opposite to the first and second slots. The third slot is located corresponding to the third passage of the body. A curved engaging member has two holes and two one-direction valves are engaged with the two holes. A groove is defined in an end of the engaging member and a seal ring is engaged with the groove. The engaging member is received in the operation rod so that when rotating the operation rod, the third slot communicates with the third passage, the first and second slots communicate with the first and second passages in opposite proportional change.
The primary object of the present invention is to provide a mixing unit for an individual hydration device which is attached to the user's belt or the backpack. By rotating the operation rod, the two different liquids can be served in desired mixture ratio.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The regulator 2 includes a cylindrical body 21, an operation rod 22 and a connection assembly 23. The body 21 has a restriction ring 214 is connected to an end of the body 21 and of indexes 215 are marked on an outside of the body 21. An operation rod 22 is rotatably inserted in the body 21 and a knob 221 is connected to an end of the operation rod 22. A marker 2211 extends inward and radially from the knob 221 and has a hook portion 22111 which is engaged with the restriction ring 214. Two first paths 222A, two second paths 222B, a third path 222C and two fourth paths 222D are defined through the operation rod 22 and located at four directions such as 0 degree position, 90 degree position, 180 degree position and 270 degree position. The first, second, third and fourth paths are in communication with each other. A first, second and fourth pads 222A1, 222B1, 222D1 are respectively engaged with the first, second and fourth paths 222A, 222B, 222D, while the third path 222C is engaged with a third pad 222C1 which includes a one-direction valve with a slits 222C2. There are two separated openings defined in the third pad 222C1. The operation rod 22 has a groove 223 defined in an end thereof and a seal ring 2230 is engaged with the groove 223.
The connection assembly 23 is attached to the body and includes a connection piece 231 and a connection member 232, wherein the connection piece 231 has a clip member 2311 which is fixed to the root portion of the third connection tube 213 and the other end has a hook 2312 engaged between the first connection tube 211 and the second connection tube 212. The connection piece 231 includes a rectangular protrusion 2313 protruding from a mediate portion thereof and an adjustment slit 2314 is defined in the protrusion 2313. The connection member 232 has a rectangular engaging hole 2321 which has an adjustment slot 2322. The protrusion 2313 engaged with the engaging hole 2321.
