Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
Referring to Fig.1-9, the toothpaste conveying assembly of the electric toothbrush of the embodiment of the present invention, including pipeline 1, brush teeth device 2 with
And the toothpaste box 3 for containing toothpaste.Specifically, pipeline 1 includes hose 11 and hard tube 12,11 one end of hose and toothpaste box 3 connect
Logical, 11 other end of hose is connect with one end of hard tube 12；Device 2 of brushing teeth is equipped with through-hole 220, the other end and through-hole of hard tube 12
220 connections, so that the toothpaste in toothpaste box 3 is followed by hose 11, hard tube 12, and flow to device 2 of brushing teeth via through-hole 220
On.
The toothpaste conveying assembly of above-mentioned electric toothbrush and electric toothbrush, the pipe formed by being provided with hose 11 and hard tube 12
Road 1, toothpaste box 3 are connect by pipeline 1 with device 2 of brushing teeth, and wherein 11 both ends of hose are connect with toothpaste box 3 and hard tube 12 respectively,
And hard tube 12 is connect with device 2 of brushing teeth again, the toothpaste in such toothpaste box 3 can be flowed to and be brushed teeth by hose 11 and hard tube 12
On device 2, in order to user of toothbrushing, since what is be directly connected to toothpaste box 3 is hose 11, softness of the hose 11 due to itself
Controllability, the more convenient adjusting when installing to toothpaste box 3 and hose 11 will not generate internal stress due to bending,
Preferably protect the other component inside electric toothbrush.
In the present embodiment, pipeline 1 is made up of hose 11 and hard tube 12, and the length of hard tube 12 is equal to or more than hose
11 length；In this way can be too long to avoid hose 11 and there is bending deformation, and then influence toothpaste smooth conveying.
Referring to Fig.1, Fig. 9, it is preferred that toothpaste mouth 31 is convexly equipped on toothpaste box 3,11 one end of hose is connect with toothpaste mouth 31.
Wherein, toothpaste mouth 31 can be the projection structure formed at the surface that toothpaste box 3 is recessed, be also possible to not have in toothpaste box 3
The projection structure formed on the end face of recess, can also be other specific set-up modes or shapes, in present embodiment, specifically
, toothpaste mouth 31 is convexly equipped in toothpaste box 3 and is not recessed close to one end of hose 11, and at setting.By being protruded above in toothpaste box 3
Toothpaste mouth 31 is set, on the one hand can guarantee the use that the toothpaste in toothpaste box 3 is maximized, avoids toothpaste is excessive from remaining in
In toothpaste box 3, another aspect toothpaste box 3 is docked with hose 11, the more convenient operation in installation and replacement new toothpaste box 3.
Referring to Fig. 2, Fig. 9, specifically, hose 11 includes main part 111 and first connecting portion 112, first connecting portion 112 is set
In main part 111 close to one end of toothpaste box 3, first connecting portion 112 is connect with toothpaste mouth 31.In the present embodiment, main part
111 be round tube shape structure, and first connecting portion is cylindrical, and first connecting portion 112 is convexly equipped in one end of main part 111, and first connects
The internal diameter of socket part 112 is greater than the internal diameter of main part 111.During installation, the toothpaste mouth 31 on toothpaste box 3 and first connecting portion 112
The connection to realize toothpaste box 3 Yu hose 11 is docked, the toothpaste in toothpaste box 3 can flow into first connecting portion from toothpaste mouth 31
112, and then flow into main part 111, it is flowed into hard tube 12 again via main part 111, that realizes toothpaste stablizes conveying.At it
In his embodiment, the junction of first connecting portion 112 and main part 111 is internal diameter gradual change type structure.
Referring to Fig. 9, in one embodiment, toothpaste mouth 31 includes lug boss 311 and docking section 312, and lug boss 311 is convexly equipped in
3 one end face of toothpaste box, docking section 312 are set to the one end of lug boss 311 far from toothpaste box 3, first connecting portion 112 and docking section
312 connections.Specifically, in the present embodiment, docking section 312 is cylindrical, it is formed between docking section 312 and lug boss 311
Step, the outer diameter of docking section 312 are equal to or more than internal diameter (the i.e. docking section 312 and first connecting portion 112 of first connecting portion 112
Between be similar to interference fit), docking section 312 is inserted in first connecting portion 112, and first connecting portion 112 is far from main part
111 one end is connected to step.In this way when realizing that toothpaste box 3 is connected to hose 11, only cylindrical shape need to be inserted into docking section 312
First connecting portion 112 in；Docking section 312 is cylindrical, is to collect toothpaste out of, cylinder hole on docking section 312
Middle outflow；First connecting portion 112 is cylindrical, convenient for docking section 312 and 112 abutting joint of first connecting portion, simplifies installation behaviour
Make, improves installation effectiveness；Further, the outer diameter of docking section 312 is made to be equal or slightly larger than the internal diameter of first connecting portion 112,
It can make docking section 312 and the closer connection of first connecting portion 112, go out after avoiding docking section 312 from being inserted into first connecting portion 112
Show gap and toothpaste is caused to be revealed, and the elasticity of hose 11 itself, it is also possible that above-mentioned docking section 312 is smoothly inserted into first
Interconnecting piece 112.
