Abstract

The utility model relates to a breathing mask nasal line supply mechanism. A photoelectric switch is utilized to cooperate with the angular adjustment of two fanning strips in order to control the length of the conveying nasal line. The nasal lines are combined with breathing masks with different sizes to obtain the easily adjustable controlling effect. The assembly of the cutting transfusion is in no need of replacing to obtain the progressive requirement.

Description

A kind of De Salle's line feed mechanism of mouth mask

Technical field

The utility model is the structure that provides the mouth mask De Salle's line about a kind of, can change its length easily, adapts to the mouth mask of various sizes, promotes its practical value.

Background technology

Generally when making the adhesive-bonded fabric mouth mask, to add the De Salle's line that can change fixed angle usually in the inboard of mouth mask upper limb with one, provide the user to put on mouth mask after, with defeating, it is fitted on the bridge of the nose by the De Salle's line position, reach effective driving fit purpose.As illustrated in fig. 1 and 2, it is the maker installation drawing of general mouth mask, and its De Salle's line feed mechanism 1 comprises two groups of relative rubber wheels 11, and establishes with cutting wheel 2 at rear side, utilizes its cutting knife 21 to cut off De Salle's line 3, and the combination of carrying out with the mouth mask adhesive-bonded fabric is provided.Known cutting wheel 2 mainly is to utilize inner cam to drive, and makes it when rotating a circle, and just can cut De Salle's line 3 once, the De Salle's line 3 of regular length is provided, when the size of mouth mask or size not simultaneously, just must change inner cam or cutting wheel 2, palpus to adapt to.The mode of this kind replacing quite bothers, and must prepare many group spare parts, just can provide the De Salle's line of cutting different length, therefore rather inconvenience.

Summary of the invention

The purpose of this utility model is the defective that overcomes above-mentioned prior art, a kind of De Salle's line feed mechanism of mouth mask of improvement is provided, utilizes single modular construction, cooperate optoelectronic switch, get final product the sequential that simple and easy setting cutting wheel rotates, finish the effect of the De Salle's line of cutting different length.

The purpose of this utility model provides that following technical proposals realizes, the De Salle's line feed mechanism of mouth mask provided by the utility model comprises two groups of relative rubber wheels, and establish with cutting wheel at rear side, utilize its cutting knife to cut off De Salle's line, the combination of carrying out with the mouth mask adhesive-bonded fabric is provided; Its feature mainly is to establish with two coaxial fanning strips in the inside of mouth mask maker, can adjust and change both relative angles, make the angle difference of its breach, be provided with two optoelectronic switches in the side of two fanning strips, control the activation of rubber wheel respectively and close, in addition the opposite side at internal body is provided with another optoelectronic switch, and the inner, cutting wheel axle center is provided with one and can controls the induction rod that cutting wheel stops.

Above-mentioned explanation only is the general introduction of the utility model Partial Feature, for making the professional person who reads specification, can clearer understanding technological means of the present utility model, and can implement according to this according to this description, so cooperate diagram to be illustrated to the utility model, and the following stated is not that the utility model is done any pro forma restriction only in order to explain preferred embodiment of the present utility model.

Description of drawings

Fig. 1 is the structural representation of the mouth mask maker of general prior art;

Fig. 2 is the outside drawing of the De Salle's line feed mechanism of general prior art;

Fig. 3 and 4 is respectively the utility model fanning strip controlling organization stereogram;

Fig. 5 to 7 is respectively the action cooperation figure that De Salle's line internal control mechanism was supplied with and cut to the utility model.

The figure number explanation:

1 De Salle's line feed mechanism; 11 rubber wheels; 2 cutting wheels; 21 cutting knifes; 22 induction rods; 3 De Salle's lines; 4,4 ' fanning strip; 51,52,53 optoelectronic switches.

The specific embodiment

Referring to Fig. 3 and shown in Figure 4, the utility model is mainly established in the inside of mouth mask maker with two coaxial fanning strips 4,4 ', can simple and easy adjustment and change the two relative angle, make the angle difference of its breach.Please consult shown in Figure 5 again, be provided with two

optoelectronic switches

51,52 in the side of two fanning strips, control the activation of rubber wheel 11 respectively and close, the opposite side at internal body is provided with another optoelectronic switch 53 in addition, and the inner, cutting wheel 2 axle center is provided with an induction rod 22, can control stopping of cutting wheel 2.

See also shown in Fig. 5 to 7, when fanning strip 4 turns to electric switch 51, promptly activate rubber wheel 11 drive De Salle's lines 3 and advance, and when fanning strip 4 ' leaves optoelectronic switch 52, rubber wheel 11 just stops, activate cutting wheel 2 simultaneously and rotate, and turn around, when 22 pairs of induction rods arrive optoelectronic switch 53 when cutting wheel 2 revolves with cut-out De Salle's line 3, cutting wheel 2 just stops, to treat the cutting rotation of next time, circulate by this, the De Salle's line that can supply with equal length is combined in mouth mask.

When desire change to be supplied with the length of De Salle's line 3, as long as adjust two fanning strips 4,4 ' relative angle, can control the supply length of De Salle's line 3, just activate cutting wheel 2 then and cut off.Like this, the utility model obviously can with single component, be finished the De Salle's line of control different length under simple the adjustment, adapting to different mouth masks, thereby has practicality and progressive.

Above-listed detailed description is specifying at a possible embodiments of the present utility model, and this embodiment is not in order to limit claim of the present utility model, all do not break away from the utility model skill spirit institute for it equivalence implement or change, all should be contained in the claim that the application asks.

Claims
