Abstract
Description
- Disclosed is a liquid dispensing mechanism, wherein the rollers provided on a planet device push the liquid stored in a transmitting hose, thereby transmitting the liquid from the supplying end to the user's end such that the invention is adapted to automatic liquid dispensers.
- For example, generally, a liquid soap dispenser for dispensing cleanser/hand cleanser installed in bathrooms or washing rooms is mechanically operated by hand or presents as an electronic sensing type. As the former would dispense a predetermined amount of liquid at each press, the user must further press the button to require more liquid; whereas the later can use an electric-eye sensor to control the liquid dispensed though, the liquid dispensing mechanism should rely on the traditional mechanical structure. A liquid dispensing mechanism is shown in
FIG. 1 , wherein through aspeed reducer 12, the power of amotor 11 drives arotating plate 13 which is axially connected to a connectingbar 14 and apiston 15, thereby thepiston 15 can repeat an up-and-down movement in acylinder 16, and the liquid stored in the storage tank (not shown) can be sucked into ainlet 18 on thecylinder 16 wall and subsequently be pushed out of anotheroutlet 19 to the user's hand. - The
speed reducer 12 is provided on a side thereof amaximum switch 20. On an end of themaximum switch 20 is provided aspring 21 which can activate or shut down the operation of themotor 11 by the contact of the left and right extrudingpoints 22 on the surrounding of the rotatingplate 13 during the operation of therotating plate 13, thereby thepiston 15 pushes the liquid soap out, and sucks and stores an amount of liquid soap for the next dispense. - Although an automatic soap dispenser can avoid the users from the trouble of manually or overly push the button, there still exist some disadvantages in the use thereof, e.g.:
- 1. As the automatic soap dispenser is driven by a motor, a speed reducer, a connecting rod and a piston, the breakdown rate of the entire mechanism is relatively high in view of the numerous transmitting units.
- 2. By way of the push by the piston, each piston stroke can only provide a limited amount of liquid soap. As the amount of the soap dispensed cannot be increased in the form of consequent dispenses, there is difficulty in overcoming the various users' needs for different amount of liquid soap.
- 3. The piston type soap dispense may render the actions of sucking and pushing the liquid soap by the up-and-down piston stroke. However, as the liquid soap is sucked by way of siphon, the form of the liquid soap is preferably limited to well floating liquids, rather than those in the form of toothpaste or those containing scrubbing particles, which would be stocked in the inlet.
- Means of Solving
- To improve the disadvantages of the traditional automatic soap dispensers, the invention provides a soap dispensing mechanism which is different from piston type soap dispenser. The invention primarily provides a planet device which is a plate provided with a number of axles on the surface thereof. Each axle is axially connected to a roller. The planet device is mounted in a housing. A hose in the form an arc is provided in-between the inner rim of the housing and the outer surface of the rollers of the planet device. The above mechanisms are driven by a motor. The axis of the motor passes through the plate surface and a side of the housing, whereas the surrounding of the motor contacts with the outer surface of each roller, thereby transmitting the rotating power of the motor to each roller, and activating every roller to rotate and sequentially rotate the whole plate. The rotation of the rollers driven by the rotating plate generates a circular pushing power to the hose surface, and the liquid soap carried in the hose is pushed out sequentially, thereby the liquid soap is socked into another inlet.
- The primary object of the invention is to provide a sequentially rotating liquid dispensing mechanism, the operation of which can be freely determined to timely adjust the amount of the liquid dispensed, thereby satisfying various needs for liquid amount in different environments.
- The secondary object of the invention is to provide a hose which can supply a greater space and section for the liquid float such that substances as toothpaste, or liquid containing scrubbing particles, tomato juice, soybean sauce, juice, coffee and mineral water can be adapted in the invention as well.
- A further object of the invention is to provide a motor powder which can directly drive the rollers of the planet device to rotate, and the rollers can directly press the hose to operate the soap dispense. As the mechanisms involved in the invention are simple, the power needed and the costs for designing the integral mechanism can be decreased, and the maintenance of the mechanism is rather convenient.
- As shown in
FIGS. 2 a and 3, the preferred embodiment of the invention includes aplanet device 3, ahose 4 and ahousing 5, wherein theplanet device 3 is placed in the bottom of thehousing 5 and provided with arotating plate 31. A number ofaxles 32 extrude from the plate surface, each of theaxles 32 is sheathed by aroller 33, and the outer surface of therollers 33 is distanced from each other. Thehose 4 is in the form of an arc provided in-between the inner rim of thehousing 5 and the outer surface of eachroller 33 of theplanet device 3. Twoopposite extrusions 40 are provided on the hose and engaged in thegrooves 50 in the left and right ends of thehousing 5, thereby avoiding thehose 4 from sliding axially. - Now refer to
FIGS. 2 b and 3 for the operation of the invention. The motor 6 is positioned in an outer side of thehousing 5, and theaxis 60 of the motor passes through the center of therotating plate 31 of theplanet device 3, and then is positioned among therollers 33 such that theaxis 60 is in contact with the outer surface of eachroller 33. As theaxis 60 of the motor rotates clockwise, therollers 33 directly contacted thereby are activated to rotate counterclockwise and touch the surface of thehose 4. Since thehose 4 is fixed in the housing, through theaxles 32, therotating plate 31 which bears therollers 33 rotates clockwise to activate the rollers borne by theaxles 32 to rotate together. Meanwhile, the surface of thehose 4 is pushed by the force of its self-rotation and the rotation of therollers 33 driven by therotating plate 31, a sequential pushing force generates along the direction of the hose axis, thereby air is pushed and transmitted from aninlet end 41 to anoutlet end 42. Likewise, when theinlet end 41 is inserted into a liquid soap storage tank (or tomato juice, soybean sauce, juice, coffee or mineral water storage tank ) (not shown), theliquid soap 7 will be sequentially socked from the storage tank and transmitted to theoutlet end 42 for users' dispense. The above structure may provide a desired amount of liquid by simply adding a control circuit to control the operating time of the motor 6. -
