Specific embodiment:

The utility model is further described with specific embodiment below, referring to Fig. 1-Fig. 5:

A kind of back suction pulsating respirator, including being worn on facial masks 1 and for providing the box body 2 of purification air, The mask 1 and box body 2 are connect by tracheae 3, box body 1 can the gas in forced air enter, to provide gas in mask 1 Body, the tracheae 3 are connect with mask 1 by connector 4, and upper plenum 41 and lower cavity 42, upper plenum 41 are formed in the connector 4 It is communicated with mask 1, lower cavity 42 is communicated with tracheae 3, offers through-hole 43 between upper plenum 41 and lower cavity 42,43 energy of through-hole Upper and lower two cavity gas is enough allowed to circulate, so that box body 2 is supplied gas to mask 1.It is hinged in the upper plenum 41 for stopping The side wall of the metal cover board 44 of 43 outlet of through-hole, upper plenum 41 is equipped with for driving the metal cover board 44 to resist the through-hole 43 The spring 45 of outlet, under normal condition, spring 45 is constantly in the state for resisting metal cover board 44, make the gas of lower cavity 42 without Method is transported in upper plenum 41, and the upper plenum 41 is provided with the conducting wire A46 and conducting wire B47 whether control box body 2 works, conducting wire A46 and conducting wire B47 sequentially passes through the lower cavity 42 and tracheae 3 and is ultimately attached to box body 2, conducting wire A46 and the metal Cover board 44 is connected, and conducting wire B47 is placed in 41 cavity of upper plenum, when rotating metal cover board 44, the conducting wire B47 and metal cover Plate 44 contacts, and conducting wire A and conducting wire B is in a kind of state of open circuit in upper plenum 41, and lower end passes through lower cavity 42 and finally in box Forming circuit in vivo, when user wears the respirator, box body 2 is in following two state:

When user exhales, normally breathed out normal through the exhalation vents on conventional mask, it is worth mentioning at this point that, exhaling on mask Port often all using unidirectional design, i.e. only export but no import, ensures that toxic gas cannot be sucked out of mask；

When user's air-breathing, the upper and lower cavity in connector 4 can generate draught head, using suction, overcome the bullet of spring 44 at this time Power, the metal cover board 44 can be rotated along articulated shaft, and metal cover board 44 is contacted with conducting wire B47 at this time, so that off state disappears It loses, motor works in box body at this time, provides purification gas for user, it is worth mentioning at this point that, the end of conducting wire B47 and metal cover board When 44 contact, the sense object that end uses is metal, such as: copper, aluminium or iron.

Structure in above-mentioned connector 4 can allow respirator more humane, will supply gas, exhale when making to really need air-breathing It is not had when gas and persistently supplies gas and cause the phenomenon that having difficulty in breathing, meet human body pulsation.It is noted that connector 4 It is interior that the cost calibrated when production can be reduced using mechanical design, metal cover board can be controlled with the mode of photosensitive sensors It is freely rotated, but precision is affectedly bashful difficulty, and higher cost.

The utility model is further arranged to, and 2 lower end of box body is hinged with box cover 21, if offering on the box cover 21 Dry air inlet 22 is provided with the purify cavity 23 communicated with the tracheae 3 in box body 2, is provided with filter screen 24 in purify cavity 23, should Purify cavity 23 can place such as activated charcoal, and active powdered carbon is prevented in box, play gas defence, anti-formaldehyde, paint and other effects, while mistake Strainer can further allow impurity barrier in purify cavity 23, prevent it from entering in mask, the lower end of purify cavity 23 is provided with dynamic Power device 25, power device 25 include power supply and blower, and power supply is that blower is powered, and the forced motor of operating allows the gas in air It flows into box body 2, by purify cavity 23,22 energy of several air inlets that will be opened up on the air delivery of purification to mask and box cover The air in air is enough facilitated to enter in box body 2.

The utility model is further arranged to, and the front end of the purify cavity 23 offers mounting hole 231, the box cover 21 with It is provided with filter cotton frame 26 between purify cavity 23, mounting portion 261 is provided on filter cotton frame 26, mounting portion 261 is plugged in described In mounting hole 231, mounting portion 261 is communicated with purify cavity 24, and 261 upper end cover of mounting portion is equipped with filter cotton, filter cotton frame benefit With the molding mounting portion 261 in one side, purify cavity 23 is become could be by the closed of entrance after must first go through filter cotton frame 26 Cavity, and using the filter cotton on filter cotton frame 26, effectively prevent granule foreign present in air.

The utility model is further arranged to, and 26 side of filter cotton frame, which is movably hinged with, presses the filter cotton for covering Body cradle 27, the other side of filter cotton frame 26 is provided with the buckle 271 for fixed hinge frame 27.Filter cotton passes through body cradle 27 withhold, and facilitate the replacement of filter cotton, and it is more secured to be capable of fixing filter cotton, it is worth mentioning at this point that, the mistake Filter pulp can be easy to clean, recycling and reusing.

The utility model is further arranged to, the hinge buckle and the box that the box cover 21 is arranged by 21 two sides of box cover Body 2 fastens.When box cover 21 is opened from box body 2, the hinge buckle on box body two sides is released, box cover 21 is turned over downwards at this time, To achieve the purpose that opening, and make above-mentioned filter cotton more convenient when replacing.

The utility model is further arranged to, and 2 upper end of box body is hinged with control box 28, and control box 28 passes through hinge card Button fastens with the box body 2, and the control box 28 connects the power supply and blower by conducting wire, includes in the control box 28 There are temperature control module, voltage display screen and electricity alarm device.Controlling is some common circuit assurance modules in box 28,

Such as: temperature control module, the display screen of front end shows human body temperature in normal use process, and one end is more than normal Body temperature can generate buzzing alarm, effectively prevent user's heatstroke；

Voltage display screen is mainly to show battery level information, and display rotation speed of fan and human body temperature are shown etc.；

Electricity alarm, primarily to when the intracorporal battery capacity of display box is too low, warning note effect.

The utility model is further arranged to, and the connector 4 is connect in such a way that spiral is clamped with mask 1.Which Connector 4 and mask 1 can be facilitated to install.

The utility model is further arranged to, and the rear side of the box body 2 is fixed with the clamping plate for being clipped in user's waist. For some professional demand, waist, which presss from both sides, can be placed at the behind of user, and comparison is put in front of waist, behind bring it is more clean Gas reduces damage of the pernicious gas to user.

Working principle: the mask of respirator is worn on face by user, and box body is worn on waist, user's air-breathing, by overhead The conducting wire A of chamber is contacted with metal cover board, and conducting wire A and conducting wire B are successfully formed circuit, and motor starts operation in box body at this time, will Gas in air is forced into box body, into box body in after, first pass through filter cotton and carry out simple contaminant filter, enter back into Purify cavity, by the filtering material in purify cavity, then the filter screen by being arranged on rear side of purify cavity, finally entered again by tracheae Mask provides good gas for user, avoids conventional ventilators from being continuously user and supplies gas, causes to have difficulty in breathing.

Above-described embodiment is only one of preferred embodiment of the utility model, and the implementation of the utility model is not limited with this Range, therefore: the equivalence changes that all shape, structure, principles according to the utility model are done should all be covered by the guarantor of the utility model Within the scope of shield.
