Abstract
The invention discloses a fireplace outdoor air intaking device which comprises an air intaking box at the bottom of a fireplace. An outer air intaking pipe is connected to the rear side of the air intaking box. An outer air inlet communicated with the outer air intaking pipe is formed on the rear side of the air intaking box. The sectional area of the outer air inlet is smaller than the cross sectional area of the outer air intaking pipe. An air retaining plate matched with the outer air inlet in size is disposed at the outer air inlet. The front end of the air retaining plate is connected with an adjusting plate through a connecting rod. The adjusting plate is connected with a push-pull rod. The front end of the push-pull rod extends out of the air intaking box. The fireplace outdoor air intaking device is reasonable in design, simple in structure and applicable to fireplace outdoor air intaking, outdoor air intaking and indoor air intaking can be switched, good indoor air can be kept according to actual conditions, and physical and psychological heath of people can be guaranteed.
Description
Technical field
The present invention relates to a kind of fireplace, relate in particular to the outdoor air-intake device of a kind of fireplace.
Background technology
At present, fireplace burning air inlet system both domestic and external is generally the room air adopted, it is combustion-supporting that the air inlet structure of air bottom fireplace directly extracts room air, this defect of the combustion system existence of indoor air intake that only adopts is: indoor in winter is generally all airtight, indoor air capacity can be because the burning of fireplace reduces, indoor oxygen content tails off, thereby has influence on the normal living environment of people, and people's health is damaged.In addition, reaching now Foreign Architecture standard in the future also all requires the fireplace burning to use outdoor air.Therefore, fireplace only utilizes the mode of indoor air intake burning to need badly to be improved.
Summary of the invention
The present invention, in order to solve weak point of the prior art, provides a kind of outdoor air-intake device of fireplace that can maintain indoor good air ambient.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the outdoor air-intake device of fireplace, comprise the inlet box that is located at the fireplace bottom, the rear side of inlet box is connected with the external air inlet pipe, the inlet box rear side offers the external air inlet mouth be communicated with the external air inlet pipe, the sectional area of external air inlet mouth is less than the cross-sectional area of external air inlet pipe, external air inlet mouth place is provided with the deep bead adaptive with external air inlet mouth size, the front end of deep bead is connected with adjustable plate by connecting rod, and adjustable plate is connected with the pull bar that front end stretches out inlet box.
The described adjustable plate trench structure that front transverse slat, middle stringer board and rear transverse slat form of serving as reasons, the rear end of connecting rod is threaded on rear transverse slat, the deep bead rear side is provided with link, the bending of connecting rod rear end is articulated on link, middle stringer board and pull bar are connected by screw, and the front end of inlet box is provided with the guide pad moved forward and backward for limiting pull bar.
Described inlet box bottom offers interior air inlet, interior air inlet place is provided with the cover plate for air inlet in shutoff, front transverse slat front side is connected with transverse vertical plate, transverse vertical plate front surface top is provided with upper flat plate, the cover plate upper surface is provided with limited post, and the limited post upper sleeve through has the Compress Spring between upper flat plate and cover plate; Promote backward pull bar, driving deep bead by adjustable plate moves forward in the external air inlet pipe, the external air inlet mouth is opened, adjustable plate drives cover plate and moves forward to interior air inlet place by the air inlet shutoff, pull forward pull bar, deep bead is during by the shutoff of external air inlet mouth, and cover plate leaves interior air inlet, and interior air inlet is opened.
Described pull bar front end is provided with balanced handle.
Adopt technique scheme, the air inlet of external air inlet pipe is connected to outdoor, and hand-held balanced handle promotes pull bar can make the external air inlet mouth open, realize that outdoor air intake is combustion-supporting, pull pull bar can make deep bead that the external air inlet mouth is closed, interior air inlet is opened, and realizes that indoor air intake is combustion-supporting.The sectional area of external air inlet mouth is less than the cross-sectional area of external air inlet pipe, can guarantee that like this deep bead is pushed in the external air inlet pipe, and external air inlet mouth and external air inlet pipe are penetrating.The rear end of connecting rod is threaded on rear transverse slat, can regulate like this position of deep bead.Compress Spring plays holddown plate, the effect that cover plate is contacted with inlet box bottom surface inwall all the time.
The present invention is reasonable in design, simple in structure, for fireplace provides a kind of structure of outdoor air intake, can make outdoor air intake and indoor air intake change simultaneously, like this can be according to air ambient good in the actual conditions holding chamber, for people's physical and mental health provides safeguard.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is top view of the present invention in Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the outdoor air-intake device of fireplace of the present invention, comprise the inlet box 2 that is located at fireplace 1 bottom, the open top of inlet box 2, inlet box 2 top are fixedly connected with fireplace 1 bottom, the rear side of inlet box 2 is connected with external air inlet pipe 3, inlet box 2 rear sides offer the external air inlet mouth 4 be communicated with external air inlet pipe 3, the sectional area of external air inlet mouth 4 is less than the cross-sectional area of external air inlet pipe 3, external air inlet mouth 4 places are provided with the deep bead 5 adaptive with external air inlet mouth 4 sizes, the front end of deep bead 5 is connected with adjustable plate by connecting rod 6, adjustable plate is connected with the pull bar 7 that front end stretches out inlet box 2.
The adjustable plate trench structure that front transverse slat 8, middle stringer board 9 and rear transverse slat 10 form of serving as reasons, the rear end of connecting rod 6 is threaded on rear transverse slat 10, deep bead 5 rear sides are provided with link 11, connecting rod 6 rear end bendings are articulated on link 11, middle stringer board 9 is connected by screw 12 with pull bar 7, and the front end of inlet box 2 is provided with the guide pad 13 moved forward and backward for limiting pull bar 7.
When the present invention uses in work, promote backward pull bar 7, driving deep bead 5 by adjustable plate moves forward in external air inlet pipe 3, external air inlet mouth 4 is opened, adjustable plate drives cover plate 15 and moves forward to interior air inlet 14 places by the air inlet shutoff, pulls forward pull bar 7, and deep bead 5 is during by 4 shutoff of external air inlet mouth, cover plate 15 leaves interior air inlet 14, and interior air inlet 14 is opened.So just can realize the conversion of outdoor air intake and indoor air intake.
