Description

Piston like toothbrush with tooth-paste supply function

The present invention relates to a kind of piston like toothbrush, more particularly relate to a kind ofly can store toothbrush inside to toothpaste, discharge an amount of piston like toothbrush that uses toothpaste on demand with functions of physical supply with tooth-paste supply function.

In general, the structure of ordinary toothbrush and using method as shown in Figure 1, its handle 11 is connected by connecting portion 12 with toothbrush head 13, there is bristles 14 toothbrush head 13 upper ends.Its using method is, earlier toothpaste squeezed on bristles 14, and the user catches handle 11, brushes teeth with the bristles 14 of toothbrush head then.

But such toothbrush has several places shortcoming, must squeeze toothpaste on bristles 14 when brushing teeth at every turn, therefore can bring a lot of inconvenience and agitation.Also have, therefore careless can drop to the ground toothpaste or squeeze too many of user waste toothpaste or the like sometimes.

In order to overcome above shortcoming, the purpose of this invention is to provide a kind of piston like toothbrush, be stored in toothbrush inside squeezing the toothpaste that on bristles, uses in the past, it is extruded in the bristles in right amount uses again.

In order to achieve the above object, the present invention proposes a piston like toothbrush with tooth-paste supply function, comprise toothbrush handle, have the toothbrush head of bristle and the coupling part that the two is continuous, it is characterized in that, toothbrush handle portion within it has the filler opening that is used for filling toothpaste, be provided with reciprocating plunger in this filler opening, have the toothpaste bullport in the inside of toothbrush head and coupling part, this toothpaste bullport communicates with the toothpaste filler opening.

Advantageously, above-mentioned toothbrush handle and toothbrush head are dismountable.

Advantageously, have in the above-mentioned toothpaste bullport and prevent to be extruded into the toothpaste of bristles and the check valve of the filthy adverse current in the oral cavity.

Advantageously, the shell of above-mentioned toothbrush handle is transparent.

Advantageously, above-mentioned plunger has hermetic unit, and the end has increased pressure board thereafter.

As described abovely can know, toothbrush head is connected by the coupling part with handle, there is the filler opening of depositing toothpaste handle inside and toothpaste is guided to toothpaste bullport in the bristles, when advancing plunger, exist the toothpaste in the toothbrush to be extruded, this toothpaste can be removed us from and brush teeth at every turn and will squeeze toothpaste out of a tube, or less or many, or the like trouble because handle casing is transparent, we can adjust use amount of paste ourselves.Therefore, also needn't waste unnecessary toothpaste.It is toothbrush and Toothpaste integrated novel toothbrush.

Toothbrush outward appearance with toothpaste functions of physical supply also with some difference of toothbrush in the past, has feeling of freshness, and uniqueness is arranged, and therefore the curiosity that can inspire children allows them brush teeth of one's own accord, form one regular, the tooth-brushing habit of validity.

For a person skilled in the art, by with reference to the accompanying drawings and read following detailed description, can be expressly understood these and other characteristics of the present invention.

Below, will be further described explanation to the present invention in conjunction with the accompanying drawings and embodiments.

Shown in Fig. 2 and 3, the structure of an embodiment of the piston like toothbrush with tooth-paste supply function of the present invention comprises, toothbrush handle 110 and the toothbrush head 120 that has bristles 122, the two connects by coupling part 130, there is the toothpaste filler opening 111 of depositing toothpaste handle 110 inside,

toothbrush head

120 and 130 inside, coupling part have toothpaste that handlebar leaves filler opening 111 in and are extruded into passage on the bristles 122 by toothpaste bullport 131, when advancing toothbrush plunger 200, during toothpaste that the toothpaste filler opening in the extrusion handle 111 is 111 li, toothpaste will squeeze on the bristles 122 by toothpaste bullport 131.In order to confirm the amount of paste of 111 li of toothpaste filler openings in handle 110, handle should be transparent, and the shell of handle should have been shown graduation mark 112 expression amount of paste, also has the rearward end of handle 110 should form the support sector 113 that supports finger.

As shown in Figure 4, handle 110 and toothbrush head 120 can separately be made.Because the coupling part of handle 110 and toothbrush head 120 has external screw thread 114 and internal thread 115 respectively, so, can connect them or separate.For toothpaste is evenly distributed, discharge opening communicates with toothpaste bullport 131.

Shown in Fig. 5,6, to stay the dirt in the oral cavity and be discharged to the dirt adverse current that toothpaste and toothbrush brushed in the bristles in toothbrush in order not allow from 111 li of toothpaste filler openings, so a check valve 140 is arranged, above-mentioned check valve comes out to connect together with toothpaste bullport 131 with the semi-spherical shape projection, established in above-mentioned protruding 142 the inside and opened and closed thing 143 to open and close the toothpaste bullport 131 that connects together with it, making under above-mentioned protruding 142 spring action, above-mentioned switching thing 143 opens and closes the toothpaste bullport 131 that connects together with it.

Above-mentioned plunger has hermetic unit 210 to flow out between toothpaste pack hole 111 inner surfaces and plunger 200 outer surfaces to prevent toothpaste for 200 li.There is increased pressure board 220 in plunger back-end portion, so that finger or palm advance plunger.Also have the messenger wire 230 that is used to hang toothbrush on the increased pressure board 220.

Shown in Fig. 7 a, when inserting toothpaste, can take off the plunger 200 that is contained in 111 li of toothpaste filler openings.After toothpaste pot mouth and toothpaste pack hole 111 coincide toothpaste is extruded into 111 li of the toothpaste filler openings of plunger 200, again the plunger 200 that takes out is put into 111 li of toothpaste pack holes.

Shown in Fig. 7 b, when using piston like toothbrush, advance plunger 200 with hand push, the toothpaste that leaves 111 li of toothpaste pack holes in just is extruded on the bristles 122 by toothpaste bullport 131.

Because handle 110 shells are transparent, can know the amount of paste that the user extrudes.
