The object of the present invention is achieved like this:
A kind of dental floss comprises a dental floss holder (20) and a handle (30).Described dental floss holder (20), comprise a base portion (22) and from the extended a pair of pillar that separates each other of base portion (22) (23), and comprise one section dental floss (21), the two ends of described dental floss (21) are separately fixed at two tops of described pillar (23).Described handle (30) comprises a handle body (31) that is used for grasping, and comprises that is arranged at a handle body head one end, that be used for fixing dental floss holder (32).It is characterized in that:
The head (32) of described handle (30) has been constructed the insertion groove (33) of a perforation; First end of described insertion groove (33) forms a unlimited insertion mouth (33A), and second end of described insertion groove (33) forms a unlimited afterbody opening (33B); Described insertion groove (33) comprises a first side wall (33D) and one second sidewall (33E); Described the first side wall (33D) has been constructed a protrusion (33C) in afterbody opening (33B) position near described insertion groove;
The base portion of described dental floss holder (22) extends one downwards and inserts piece (24); Described insertion piece comprises one first side (24A) and one second side (24B); Minimum one first bogging down area (24D) of having constructed in described first side (24A), and, in the lower end of described bogging down area (24D), the minimum protrusion (24C) of having constructed.
Feature of the present invention also is:
One second bogging down area (24E) has been constructed in the lower end of described protrusion (24C) in first side (24A) of the insertion piece (24) of described dental floss holder (20).
Minimum one first bogging down area (24D) of having constructed in second side (24B) of the insertion piece (24) of described dental floss holder (20), and, in the lower end of described bogging down area, the minimum protrusion (24C) of having constructed.
One second bogging down area (24E) has been constructed in the lower end of described protrusion (24C) in second side (24B) of the insertion piece (24) of described dental floss holder (20).
First bogging down area (24D) of first side (24A) structure of the insertion piece (24) of described dental floss holder (20) and protrusion (24C) and second bogging down area (24E), with first bogging down area (24D) and protrusion (24C) and second bogging down area (24E) of described second side (24B) structure, be symmetric arrays along the axis of first side (24A) and second side (24B).
The length of second sidewall (33E) of the insertion groove of the head (32) of described handle (30) is shorter than the length of the first side wall (33D).
Usually, the shape of the thickness of described insertion groove (33) and width and insertion groove (33), adapt with the thickness of the insertion piece (24) of described dental floss holder (20) and width and shape, make described insertion groove (33) just can hold the insertion portion of described dental floss holder (20).
Untapped the time, dental floss holder (20) and handle (30) are normally isolating.Often several dental floss holders (20) are packaged in together.When needs use, get a dental floss holder (20), make the insertion mouth (33A) of bottom alignment handle head of the insertion piece (24) of dental floss holder; Then the insertion piece (24) of dental floss holder is inserted in the insertion groove (33); And continue firmly inwardly to insert; Constantly enter in the process of insertion groove (33) at insertion piece (24), the lateral protrusion (24C) that inserts piece will move down gradually, finally surmount the protrusion (33C) of the sidewall of insertion groove.At this moment, the sidewall that the base portion of dental floss holder (22) just is inserted into mouthful (33A) stops, makes dental floss holder (20) and inserts piece (24) and can not move down again.Simultaneously, the protrusion (33C) that the lateral protrusion (24C) of insertion piece also is inserted into the sidewall of groove stops, makes dental floss holder (20) and inserts piece (24) and can not move up.Dental floss holder (20) thereby be fixed.After dental floss holder (20) was fixed, user thereby can control crank (30) utilized dental floss (21) cleaning teeth on the dental floss holder.
Usually, the top of the protrusion of the sidewall of insertion groove (33C) and the bottom of inserting the lateral protrusion (24C) of piece are configured to cambered surface; The bottom of the protrusion of the sidewall of insertion groove (33C) and the top of inserting the lateral protrusion (24C) of piece are configured to the plane.Constantly enter in the process of insertion groove (33) at insertion piece (24), the lateral protrusion (24C) that inserts piece will move down gradually.When the top of protrusion (33C) of the sidewall of insertion groove was run in the bottom of the lateral protrusion (24C) that inserts piece, the protrusion (33C) that will be inserted into the sidewall of groove stopped.Because these two faces that are in contact with one another are globoidal structure, in the time produced a thrust laterally.In the upper end of the lateral protrusion (24C) that inserts piece, constructed one first bogging down area (24D).This subregion of inserting piece (24) is thinner, adds that the material that inserts piece (24) use has elasticity, thereby is easy to distortion.When laterally the thrust of the protrusion (33C) of the sidewall that is subjected to insertion groove, lateral first bogging down area (24D) position, place of inserting piece can be suitably crooked, part below lateral first bogging down area (24D) of drive insertion piece is to external rotation, thereby the protrusion (33C) that the lateral protrusion (24C) of piece surmounts the sidewall of insertion groove is inserted in permission.
The lateral protrusion (24C) that inserts piece surmounts after the protrusion (33C) of the sidewall of insertion groove, under the elastic force effect of inserting piece (24) self (elastomeric material), the following part of lateral first bogging down area (24D) of inserting piece will return to the preceding position of rotation.At this moment, the bottom of the protrusion of the sidewall of insertion groove (33C) contacts with each other with the top of the lateral protrusion (24C) that inserts piece.Because these two faces that are in contact with one another all are the planes, therefore, dental floss holder (20) can not produce thrust laterally even be subjected to pulling force upwards yet; At this moment, the protrusion of the sidewall of insertion groove (33C) will stop the lateral protrusion (24C) that inserts piece to move up.Insert piece (24) thereby be locked.
After the lateral protrusion (24C) that inserts piece surmounted the protrusion (33C) of the sidewall of insertion groove, the protrusion of the sidewall of insertion groove (33C) was accommodated in lateral first bogging down area (24D) that inserts piece.
Dental floss holder (20) has cleaned after some teeth, and its dental floss can fluff, rupture.At this moment, dental floss holder (20) just can not re-use, and need take off exhausted dental floss holder (20), changes original dental floss holder (20).In order to take off dental floss holder (20), need press...with one's finger and press the bottom of inserting piece (24), so that the bottom of inserting piece (24) is applied upwards and pressure laterally simultaneously.In the process of inserting piece (24) insertion insertion groove (33), after the lateral protrusion (24C) that inserts piece surmounts the protrusion (33C) of the sidewall of insertion groove, the bottom of inserting piece (24) can pass the afterbody opening of insertion groove (33), and stays the outside of afterbody opening (33B).This structure makes finger be easy to be pressed into the bottom of inserting piece (24).
When finger presses is inserted the bottom of piece (24), when the bottom of inserting piece (24) is applied laterally pressure, inserted the following part of first bogging down area (24D) of piece and will rotate laterally; This rotation will drive the lateral protrusion (24C) that inserts piece and move laterally, and walk around the protrusion (33C) of the sidewall of insertion groove; Insert the lateral protrusion (24C) of piece and walk around after the protrusion (33C) of the sidewall of insertion groove, insert piece (24) and be subjected to pointing the traction that upwards pressure that applies, will move up.Insert piece (24) thereby be released.After insertion piece (24) is released, can take out dental floss holder (20), it is thrown aside; And then insert original dental floss holder (20).
In the process of inserting dental floss holder (20), and in the process of taking out dental floss holder (20), inserting the following part of first bogging down area (24D) of piece will rotate laterally, so that allow the lateral protrusion (24C) that inserts piece walk around the protrusion (33C) of the sidewall of insertion groove.Usually, the length of second sidewall (33E) of insertion groove is shorter than the length of the first side wall (33D).Like this, when the part below first bogging down area (24D) that inserts piece was rotated laterally, the sidewall that just can not be inserted into groove (33) stopped.In fact, also can suitably increase the distance between second sidewall (33E) and the first side wall (33D) inserting this segment space that piece (24) need rotate, like this, the sidewall that insertion piece (24) can not be inserted into groove (33) yet stops.In this case, the length of second sidewall (33E) of insertion groove needn't be shorter than the length of the first side wall (33D).
Usually, the head of handle (32) is formed by the end extension of the handle body (31) of handle.The insertion groove of handle head (33) is " T shape " arrangement in the axis longitudinally with the handle body (31) of handle.Perhaps, the insertion groove of handle head (33) is " parallel " arrangement in the axis longitudinally with the handle body (31) of handle.
As can be seen from the above description, use method of the present invention very simple: the insertion piece (24) of dental floss holder is inserted the insertion groove (33) of the head of handle, can be with dental floss holder (20) fastening and fixing.When taking out dental floss holder (20), only with hand refers to push the bottom of inserting piece (24), and dental floss holder (20) will be released.With other disclosed dental floss relatively, it is more convenient that the present invention changes the mode of dental floss holder (20).
