Abstract

The utility model discloses a rotary chimney cover which comprises a cylindrical type cover body, a round plate type cover, a deceleration motor and a travel switch, wherein an annular baffle plate is fixedly arranged at the middle part of the outer side of the cylindrical type cover body; a motor seat for supporting the deceleration motor is fixedly arranged at the upper part of the outer side of the cylindrical type cover body; a motor output shaft transversely penetrates through the upper part of the cylindrical type cover body; a round plate cover of which the inner diameter is slightly smaller than the inner diameter of the cover body is fixedly arranged on the output shaft; the travel switch is arranged on the motor seat; and a touch point on the travel switch is arranged corresponding to a switch touch point on the output shaft. According to the rotary chimney cover, the round plate cover is automatically controlled through the travel switch so as to achieve the purpose of closing or opening a chimney and ultimately preserve heat inside a heated brick bed, so that the heat loss of the heated brick bed is effectively reduced, and the heat utilization rate is improved.

Description

The rotary type tobacco cover

Technical field

The utility model relates to a kind of rotary type tobacco cover.

Background technology

At present, at China rural area wide geographic area, particularly northern China, also generally adopt the form of heated kang to warm oneself, cook.After the burning such as the comburant in kitchen range top burner hearth such as wooden stick, stalk, hay, also there is amount of heat for later use, but because flue is in and extraneous opening state all the time, particularly smoke tube mouth is in the higher position, because pressure reduction produces suction, make also to have a large amount of indoor heats and be sucked out outside the chimney, cause in vain the loss of heat; Simultaneously, the heat in the heated kang also is difficult for preserving utilizing, and outside flue is discharged chimney, causes thermal loss.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiency of prior art, and a kind of simple in structure, rotary type tobacco cover of reducing thermal loss is provided.

The purpose of this utility model is achieved in that

A kind of rotary type tobacco cover, include drum type brake lid, circular plate type lid, reducing motor and travel switch, middle side part is fixedly installed ring baffle outside described drum type brake lid, drum type brake lid outer upper is fixed with the motor cabinet of supporting reducing motor, motor output shaft crosses drum type brake lid top, be fixed with the plectane lid that is slightly less than the lid internal diameter at output shaft, be provided with travel switch on the motor cabinet, the contact on the trip switch and the corresponding setting of the switch contact on the output shaft.

Described drum type brake lid outer upper is fixed with lock, is provided with alignment pin on the lock, this alignment pin and the corresponding bond-allocating of output shaft one end that crosses lid.

Be provided with pillar at described annular plate washer, the pillar other end extends to drum type brake lid upper space, is connected with rain-proof cover.

Be covered with safety guard on the described reducing motor, have output shaft hole on the safety guard.

Owing to adopt said structure, the lid bottom of drum type brake can coincide and place in the chimney of house owed by a citizen outside, automatically controls the circular plate type lid by travel switch, reach to chimney closing or open, finally preserve the heat in the heated kang.The utility model is simple in structure, and is easy to use, and it is few effectively to reduce heated kang heat damage, improves heat utilization efficiency.

Description of drawings

Fig. 1 is the utility model structural representation.

The specific embodiment

A kind of rotary type tobacco cover, include drum type brake lid 6, circular plate type lid 2, reducing motor 12 and travel switch 13, be fixedly installed ring baffle 7 at described drum type brake lid 6 outer middle side parts, be provided with 3 pillars 14 at described annular plate washer 7, every pillar 14 other ends extend to drum type brake lid 6 upper spaces, and are connected with rain-proof cover 1; Drum type brake lid 6 outer upper are fixed with the motor cabinet 11 of supporting reducing motor 12, be covered with safety guard 9 on the reducing motor 12, have output shaft hole 8 on the safety guard 9, motor output shaft 3 prolongs drum type brake lid 6 horizontal center lines and crosses drum type brake lid 6 tops, be fixed with the plectane lid 2 that its diameter is slightly less than lid 6 internal diameters at output shaft 3, be provided with travel switch 13 on the motor cabinet 11, the switch contact 10 corresponding settings on the contact on the trip switch 13 and the output shaft 3; Be fixed with lock 5 in drum type brake lid 6 outer upper, be provided with alignment pin 4 on the lock 5, this alignment pin 4 and the corresponding bond-allocating of output shaft 3 one ends that crosses lid 6.

During concrete the use, drum type brake lid 6 bottoms place in the smoke tube of outside, house, and ring baffle 7 guarantees the settling position that drum type brake lid 6 is on the smoke tube.When chimney covers under open and-shut mode, in the time of need to opening, by indoor switch connection power supply, reducing motor 12 work, output shaft 3 begins rotation, and circular plate type on the output shaft 3 lid 2 is in lid 6 interior rotations, when rotating to 90 when spending, complete open cylinder formula lid 6 inner spaces, reach the smoke evacuation purpose, simultaneously, travel switch 13 contacts on the motor cabinet 11 contact with the switch contact 10 on the output shaft, stop reducing motor 12 work, output shaft 3 also stops the rotation.When needs are closed chimney, plugged, reducing motor 12 work, output shaft 3 begins counter-rotating, 2 rotations of circular plate type lid, during to horizontal level, the final plant closure chimney, simultaneously, travel switch 13 contacts of motor cabinet 11 contact with the switch contact on the output shaft 3, stop reducing motor 12 work, output shaft 3 also stops the rotation, and returns to the state that original chimney lid is closed.Circular plate type lid 2 is being closed or during wide-open state, alignment pin 4 guarantees that output shafts 3 at a stable state, even strong wind weather occurs, also can keep the resistance to overturning of rotary type tobacco cover fully.
