Description: BACKGROUND OF THE INVENTION 1. Field of the Invention This invention is related to an improved tooth cleaning assembly. 2. Description of the Prior Art Generally, the toothbrush, toothpaste and tooth mug are separately placed on a vanity cabinet in the bathroom. When desired to brush teeth, it is necessary to hold the toothpaste with one hand, open the cap of the toothpaste with another hand, hold the toothbrush with the another hand, squeeze the toothpaste on to the toothbrush, and then put the toothpaste back to the vanity cabinet, thereby causing much inconvenience in use. Hence, various kinds of toothpaste squeezers have been developed to attempt to eliminate this drawback, but it is still necessary to align the toothpaste with the toothbrush and squeeze the toothpaste onto the toothbrush in use thus making them unsatisfactory and unfit for practical use. A device for providing toothpaste is disclosed in document DE 44 30 313 A1 Therefore, it is an object of the present invention to provide a tooth cleaning assembly which can obviate and mitigate the above-mentioned drawbacks.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates. With reference to the drawings and in particular to FIG. 1 thereof, the tooth cleaning assembly according to the present invention generally comprises toothpaste squeezing assemblies 10 and 10M, tooth brushes 40 and 40M, spring mugs 60 and 60M, and a rack 70. Referring now to FIGS. 2, 3 and 4, the toothpaste squeezing assembly 10 includes caps 12, tubular necks 14A, 14B, 14C and 14D, toothpaste cylinders 19, an annular member 32 with slots 33, a cover 30, a base 34 and a movable knob 37. The caps 12, tubular necks 14A, 14B, 14C and 14D and toothpaste cylinders 19 are joined together forming a toothpaste squeezer. The movable knob 37 is engaged with the base 34. The toothpaste cylinder 19 is fitted in the hole 36 of the base 34 and kept in place by the hooks 35. The upper end of the toothpaste cylinder 19 is engaged with the cover 30 which is in turn kept in place by the annular member 32. The outlet 21 at the top of the toothpaste cylinder 19 is connected with the lower end of the tubular neck to form a toothpaste squeezer. As shown in FIGS. 3 and 4, the toothpaste squeezer assembly 10 includes a cap 12 having a bottom connected with the outer upper tubular neck 14B. The inner upper tubular neck 14A is slidably fitted within the outer upper tubular neck 14B and provided with a projection 20 at the lower end. A spring 18 is fitted between the inner and outer upper tubular necks 14A and 14B. The lower end of the outer upper tubular neck 14B is slidably fitted in the outer lower tubular neck 14D which is formed integrally with the cover 30. The inner lower tubular neck 14C is slidably fitted within the outer lower tubular neck 14D and engaged with the outlet 21 of the toothpaste cylinder 19 through threads 25 or conical circular portions (not shown). The annular member 32 is mounted on the outer edge of the cover 30. A piston 20A is fitted inside the lower end of the toothpaste cylinder 19 thereby forming a chamber for receiving toothpaste 22. The piston 20A is provided with a non-return member 23 and a bottom cover 24. The toothpaste squeezer is fitted in the hole 36 of the base 34, with the hooks 35 supporting the toothpaste cylinder 19. The movable knob 37 has an engaging member 38 engaged with the engaging member 35A of the base 34. When in use, it is only necessary to press the front portion of the cap 12 so that the lugs 15 of the outer upper tubular neck 14B acts as a main axle for the interior and the axle hole 16B of the outer upper tubular neck 14B is lowered to open the cap 12 to expose the outlet 13, keep on pressing the cap 12 so that the piston 20A is blocked by the non-return member 23 thereby squeezing toothpaste 22 out of the outlet 13 and applying it to the head of the tooth brush, and then remove the tooth brush 40 and/or 40M for use. Meanwhile, the spring 18 forces the tubular necks 14A and 14B and the cap 12 to return to their original positions. Then, the cap 12 is moved by the upward force of the axle 15A to close the outlet 13. As the tubular necks are smaller than the toothpaste cylinder 19, the toothpaste will be adhesive to the tubular necks than the toothpaste cylinder 19 so that the piston 20A and the non-return member 23 will move upwardly to wait for next use. The lower end of the outer upper tubular neck 14B, the inner lower end of the outer lower tubular neck 14D, the inner upper end of the cover 30, and the upper end of the toothpaste cylinder 19 are formed with conical circular portions 26, 26A and 26B and the latter is provided with two conical circular portions 26B so that when only one conical circular portion is engaged, the spring 18 will be compressed thereby reducing the space for facilitating transmission. Then, the cover 30 is pressed to make the two conical circular portion of the latter engage with each other and the conical circular portion of the former will be disengaged for use. The upper end of the outlet 21 and the lower end of the outer upper tubular neck 14B are formed with engaging threads 27 so that the toothpaste cylinder 19 can be replaced. In addition, the cap 12 may be provided with a resiliently closed air whistle (not shown) or a music integrated circuit so that when the cap 12 is opened, music will be sent out to make it become interesting. Furthermore, the tubular necks 14C and 14D, the cover 30, the toothpaste cylinder 19 and the base 34 may be partially or all formed integrally, but the hook 35 must be made as a single component so as to enable it to replace the toothpaste cylinder 19 from the bottom. FIG. 5A is a sectional view showing the engagement between the cover 30 and the annular member 32. FIG. 5B is a sectional view illustrating the engagement between the base 34 and the movable detachable knob 37. FIGS. 6A and 6B illustrate a second preferred embodiment of the annular member, the cover and the base of the toothpaste squeezing assembly, wherein the annular member 32A, the cover 30A and the base 34A are formed with two holes and the annular member 32A may be wavy in shape. In addition, the toothpaste squeezer may be directly engaged with the detachable movable knob 37 at the bottom and with a single-hole annular member 32B at the top. Further, as shown in FIGS. 7A, 7B, 7C, 7D, 7E and 7F, the slots 33, or lugs 33A and 33B of the annular members 32, 32A and 32B may be of different types so as to be adapted for use with different types of toothbrushes 40, 40M and hook 42, thereby increasing the practicality and beauty. In other words, the present invention may be provided with one or more toothpaste squeezers to form a desired toothpaste squeezing assembly 10. The small lug 33C is a hook used for hanging long-handled dental mirror (not shown). FIGS. 8A and 8B illustrate the engagement between a toothbrush 40M with a small toothpaste squeezing assembly 10M. FIG. 9A and 9B illustrate how the toothbrush 40M is folded in a small toothpaste squeezing assembly 10M. As shown, the small toothpaste squeezing assembly 10M includes a seat 51, a spring 52, and a toothpaste squeezer. A short-handled toothbrush 40M is pivotally connected with the seat 51 at an axle 43. The toothbrush 40M is normally disposed in a straight position so that its hook 42 may be hanged on the annular member 32. When desired to carry the toothbrush 40M outside, it is only necessary to rotate the toothpaste squeezing assembly 10M through an angle of 180 degrees toward the bristles of the toothbrush 40M so that the hook 57 engages with the hole 44 of the hook 42 of the brush handle (see FIG. 10). Referring to FIG. 10, when in use, the cap 12A is depressed to squeeze the toothpaste 22 to get out of the tubular neck 14A from the toothpaste cylinder 19A and coming out of the outlet 13A and then the protuberance 58 of the hook 57 is pressed to disengage the hook 42 from the hook 57 thus causing the toothbrush 40M to a straight position for use. The toothbrush 40M may be folded after use thereby making it convenient to carry outside. The toothbrush 40M, the axle 43 and the seat 51 can be connected together by connecting plate and partially or wholely made by injection molding. The tubular neck 14C may be connected to the toothpaste cylinder 19A to make it disposable after use. Referring to FIGS. 1, 8A, 8B, 9A, 9B and 10, each of the toothbrushes 40 and 40M is provided with a hook 42 for hanging on the lug 33A of the annular member 32A and an axle 43 for engaging with the seat 51 of the toothpaste squeezing assembly. The hook 42 and the axle 43 are designed for making the bristles of the toothbrush align with the outlet 13. However, for electric toothbrushes, the hook 42 may be provided on a detachable power handle. The toothbrush 40 may be made of resilient foam plastic. FIGS. 11 and 12 are a perspective view and an exploded view of the spring mug 60, respectively. As shown, the spring mug 60 is made of a body 61, a bottom member 64, a ring member 63, a spring 67 and a handle 62. The body 61 has an annular groove 66 formed with three cavities 661 in one of which is fitted the spring 67. The bottom member 64 has a flange 65 formed with three projections 651. The bottom-member 64 is engaged with the body 61 with the projections 651 slidably fitted in the cavities 661. The ring member 63 is sleeved over the bottom member 64 to be fixedly mounted with the body 61 thereby preventing the bottom member 64 to get out of the body 61. Normally, the spring 67 forces the bottom member 64 to be located at an inclined position and the recesses portion 69 is engaged with the ring member 63 so that the spring mug 60 can be fitted into the lower portion of the rack 70. When the spring mug 60 is removed from the rack 70, the protuberances 73 at two sides of the rack 70 will adjust the position of the bottom member 64 thereby causing the spring 67 to force the bottom member 64 to go outwardly thereby increasing the capacity of the spring mug 60. The annular groove 66 with three cavities 661 may be replaced with a larger circular groove adapted to receive a single spring. Referring to FIG. 13, the upper portion of the rack 70 is formed with a hole 71 adapted to engage with a ball-shaped end 39 at the lower end of the toothpaste squeezing assembly 10. The interior of the rack 70 is divided by two partitions into three chambers for receiving spring mugs 60. The rack 70 has two holes 74 for hanging on the wall and is provided with hook plates at the bottom. The above-mentioned component parts form the tooth cleaning assembly according to the present invention. On the rack 70 is mounted toothpaste squeezing assembly 10 on which are hanged toothbrushes 40 and 40M. Spring mugs 60 or 60M are fitted within the rack 70. Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
