BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to toothpaste dispensing pen style toothbrush and, more particularly, to a toothpaste dispensing pen style toothbrush that is battery powered.
2. Description of the Related Art
Several designs for toothpaste dispensing pen style toothbrush have been designed in the past. None of them, however, include a battery to power the distribution of toothpaste.
Applicant believes that a related reference corresponds to U.S. Pat. No. 4,408,920 issued for a pocket carried toothpaste dispensing toothbrush. Applicant believes another related reference corresponds to U.S. Pat. No. 2,053,145. None of these references, however, teach of a pen style toothbrush including a pen cap and battery.
Other documents describing the closest subject matter provide for a number of more or less complicated features that fail to solve the problem in an efficient and economical way. None of these patents suggest the novel features of the present invention.
SUMMARY OF THE INVENTION
It is one of the objects of the present invention to provide a toothpaste dispensing pen style toothbrush that is modular.
It is another object of this invention to provide a toothpaste dispensing pen style toothbrush that is battery powered.
It is still another object of the present invention to provide a toothpaste dispensing pen style toothbrush that includes a pen top cover.
It is yet another object of this invention to provide such a device that is inexpensive to implement and maintain while retaining its effectiveness.
Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
BRIEF DESCRIPTION OF THE DRAWINGS
With the above and other related objects in view, the invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:
FIG. 1 includes dashed lines that represent an internal view of a toothbrush head assembly 20 mounted to the housing assembly 40.
FIG. 2 shows a rear internal view of the head assembly 20. Wherein the channel 48 is shown to connect with the rear of outlet 28A.
FIG. 3 shows the housing assembly 40 with a cap 48 mounted thereon.
FIG. 4 illustrates an overview of electrical assembly 60.
DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION
Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it basically includes a toothbrush head assembly 20, a housing assembly 40, and an electrical assembly 60.
Best illustrated in FIG. 1 housing assembly 40 may include a housing 42. The housing 42 may be a hollow cylindrical tube with a rounded bottom portion and an open top portion. The housing 42 includes an interior that may serve as a storage compartment for toothpaste, gels, or other viscous fluids. The housing 42 may further include a screw rod 44. In one embodiment the screw rod 44 may be a threaded member longitudinally disposed about an interior of the housing 42. The screw rod 44 may include a screw cap 46 mounted thereon. The screw cap 46 may include a central threaded opening to facilitate the screw cap 46 traveling along a length of the screw rod 44. It may be suitable for the screw rod 44 to include a screw rod head 44A. The screw rod head 44A may be a flattened cylindrical member with a diameter greater than that of the screw rod 44. The screw rod head 44A may prevent the screw cap 46 from traveling past a distal end of the screw rod 44. In one embodiment a user may manually rotate the rounded bottom portion of the housing 42 about the axis of the screw rod 44. The rotation of the rounded bottom portion, and by extension the screw rod 44, may allow for the upward and downward movement of the screw cap 46.
In an alternate embodiment, best shown in FIGS. 1 and 4, the housing 42 may include a motor 66 that rotates the screw rod 44 when the power button 62 is pressed. The power button 62 may actuate the motor 66 using a battery 64 as a power source. The housing 42 may include a threaded portion about an interior top edge. The interior top edge of the housing 42 may receive a threaded bottom portion of the toothbrush head assembly 20.
Best illustrated in FIG. 1 toothbrush head assembly 20 may include a toothbrush head 22. The toothbrush head 22 may include a head portion. Wherein the head portion of the toothbrush head 22 may include bristles 24 disposed about a flat oblong portion mounted thereon. As the screw cap 46 travels the length of the screw rod 44 the contents of the housing 42 are forced upward toward the top end of said housing 42. When the contents of the housing 42 arrive at the top end they are funneled through a neck 26 of the toothbrush head assembly 20. It may be suitable for the flat oblong portion of the toothbrush head 22 to further include an outlet 28A. The outlet 28A is an opening by which the contents of the housing 42 may be dispensed after traversing the channel 28. The channel 28 may be a cylindrical longitudinal pathway extending from the bottom end of the neck 26 up to the outlet 28A. Referring now to FIG. 3, it may be suitable for the toothbrush head assembly 20 to be covered by a cap 48. The cap 48 may include a hollow cylindrical interior capable of encompassing the toothbrush head assembly 20. The cap 48 may further include a clip mounted to a lateral top end. Wherein said cap 48 may engage with an exterior of the top end of the housing 42 via pressure. The cap 48 may help create a more sanitary environment for the toothbrush head 22 by maintaining said toothbrush head 22 covered while not in use. The cap 48 also has the benefit of protecting a user from incidental spilling of the contents of the housing 42 via the outlet 28A.
The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
