Figure 16 shows brush body 1 view, is convenient to the understanding to brush body itself.View A looks up from below, and view B looks down from above, and view C is that view D can see the inside of brush body 1 from brush one end.

The utility model provides, and a kind of novel to have toothpaste container and toothpaste basic element of character of extrusion device in toothpaste container is arranged be exactly brush body 1 Fig. 1, itself has multiple function, it is toothpaste container, provide toothpaste by check valve, be again the support of bristle 9, its function is identical with general toothbrush.

Shape in visible its body of B-B section shown in Figure 3 is the circle on band plane, both sides, and piston guide is made on the plane of both sides.

From Fig. 1 as seen, a check valve of being made up of double end nonreturn valve core 8 (Fig. 8) and butterfly spring 7 (Fig. 9) is arranged below the bristle 9 of brush body 1.From the D position enlarged drawing of Fig. 1 and D-D section (Fig. 5) as seen, as Fig. 9 the butterfly spring of shape after doing bending slightly therein the heart elastic force that makes progress is arranged to stop its whereabouts.The microcephaly of double end check valve spool 8 is buckled in the center of butterfly spring 7, also is subjected to an elastic force that makes progress; And the major part of spool has just covered the outlet of toothpaste.The function of check valve is dual: at first, when enough pressure acted on the toothpaste passage, pressure had overcome elastic force, and toothpaste just flows out from opening part; And when outside air pressure and internal pressure balance, the effect of butterfly spring makes closed check valve, thereby stops the water and air etc. of outside to enter toothpaste container, so just prevents that toothpaste is rotten, oxidation or dehydration etc.The check valve that double end check valve spool 8 and butterfly spring 7 are formed is contained in below the bristle 9.

In addition, shown also that from Fig. 5 and the local F ' that amplifies how protected by bristle over cap 10 bristle 9 is.Bristle after this protection just can not damage or by contaminating impurity.

Fig. 2 shows to be added in how the pressure on the toothpaste obtains by the hand-screw spiral cover in the container.Rotation spiral cover (Fig. 6) makes the corresponding rotation of piston guide rod 4 (Figure 10), and when piston just pushed away forward, the toothpaste cavity volume reduced just to produce into pressure, and this pressure makes one-way valve opens.For spiral cover is rotated smoothly, between spiral cover and brush body, add slip ring 5 (Fig. 7).The partial enlarged drawing of Fig. 2 has shown that one of spiral cover 2 and piston guide rod 4 is how to rivet together (seeing Fig. 2 and partial enlarged drawing E ') as one.Just slip ring is added in when assembling between spiral cover and the brush, the toothbrush that increases is attractive in appearance on the one hand, has also reduced the friction between spiral cover 2 and the brush body 1 simultaneously.In addition, piston guide rod 4 is connected on the brush body 1 by screw 11 elasticity, and fixing by reinforcement 12, (see figure 4).

In order to give the canned toothpaste of toothbrush, the structure of piston 3 is absolute important.Structure of piston is corrected disk, as Figure 11 both sides three symmetrical smooth flat is arranged, and stops the piston rotation, and the centre has individual tapped through hole and piston guide rod to match.Except above-mentioned tapped through hole, this piston also has another through hole to be used for canned toothpaste, the facet on piston both sides play the guiding role in order to avoid piston rotation all produces the pressure variation and do not produce possible idle running in order to guarantee each rotation of changeing spiral cover, and this guide surface is absolute important.

Mention above, the whole assembling process of the utility model before this with Fig. 1

middle part part

7,8,9 and 10 and brush body be assembled together.Second step was that piston guide rod 4 and piston 3 are packed in the brush body, was connected on the brush body with screw, and during connection, piston is in toothpaste capacity maximum position again toward position (peak) that outward turning 1 to 1.5 is changeed.Piston guide rod just becomes elasticity to be connected with screw like this.

Piston has the part 13 of a particular design, the tubule of in fact Here it is a suitable diameter, when canned by tubule can insert one with brush body 1 similar long jet pipe.Use the device of a particular design toothpaste constant speed is filled with the brush tail from brush always.The piston position that will be at the highest notch during perfusion, whole brush body will constantly shake, and make toothpaste can be full of whole space in the brush body, and remaining air also can be run away fully.Having poured into rear jet will pull out, and perfusing hole 13 is sealed with welding, bonding or other ways according to the material of piston.

Sword type toothpick shown in Figure 12 is also very important.The sword type shape of toothpick can be placed in spiral cover and the piston guide rod it reliably, and shown in the partial enlarged drawing A and B-B section of Fig. 1, the frictionally toothpick can take out or replace easily.Dove tail line the contacting of spiral cover and finger when increase rotating spiral cover arranged on the spiral cover.

From the above mentioned, toothpaste in the band toothpaste container toothbrush that the utility model provides is by the rotation spiral cover, make and then rotation of piston guide rod, thereby promote piston-advance and produce pressure, this pressure is expressed into toothpaste to toothpaste from the opening part of check valve the bristle part of toothbrush, when brushing teeth and the back of brushing teeth being by closing of check valve and stop water, air and other impurity to enter toothpaste container, thereby also avoided toothpaste to play bad chemical reaction and go bad, and also provides sanitary condition for toothbrush.
