Abstract

The utility model relates to a non-back-flowing smoke type mouth cap of a flue. A plurality of partition boards are uniformly arranged in a space layer formed between an upper and a lower wind shielding curved plates with a narrow middle part and wide circumference on the non-back-flowing smoke type mouth cap of a flue, and the space layer is divided into a plurality of funnel-shaped air ducts. A chimney plug is inserted in the middle part of the lower wind shielding curved plate, one end of a supporting lath is connected with the lower wind shielding curved plate, and the other end of the supporting lath is connected with the chimney via a fastening ring. The non-back-flowing smoke type mouth cap of a flue having the structure can prevent the back flow of smoke and have the advantages of better smoke exhaust capability, simple structure and convenient installation.

Description

The reversing smoke free blast cap
The utility model relates to a kind of reversing smoke free blast cap.
At present, existing anti-down cigarette turncap is in many styles, sum up and get up to mainly contain four types, that is: upright hat type, upright three way type, keep flat hat type and keep flat threeway (cap) formula (respectively shown in Figure of description 1-4).These anti-down cigarette blast caps all exist certain defective: (1) has the limitation of wind direction, can not all play good anti-down cigarette effect in 360 ° of wind direction scopes; (2) all hamper the unimpeded of distinguished and admirable and plume, particularly cap structure to some extent, force drift tiltedly to descend direction to discharge, resistance obviously strengthens, and has reduced suction cigarette ability.
The purpose of this utility model provides a kind of reversing smoke free blast cap that can solve the many deficiencies of above-mentioned turncap.
The technical solution of the utility model is following realization: keep out the wind on the reversing smoke free blast cap that curved slab is narrow with the centre that the curved slab that keeps out the wind down forms, some dividing plates be set equably in the space layer of Zhou Biankuan, the upper and lower curved slab that keeps out the wind is connected as a single entity, and this space layer is separated into several funnel-form ventilating ducts, on the circular hole that the chimney plug is connected down in the middle of the curved slab that keeps out the wind and the chimney plug is isometrical, one end of some support battens with under the curved slab that keeps out the wind be connected, the other end links to each other with the chimney plug by dead ring.
Because some dividing plates of reversing smoke free blast cap will be gone up, the space of keeping out the wind and forming between the curved slab down, be separated into several funnel-form ventilating ducts, when distinguished and admirable when entering this reversing smoke free blast cap porch, draught area is bigger, and when distinguished and admirable when entering this reversing smoke free blast cap centre position, ventilation section is long-pending to diminish, wind speed must be accelerated, thereby the centre position at the reversing smoke free blast cap forms a low-pressure area, like this, it is additional to force plume constantly to rise, thereby has improved suction cigarette ability, simultaneously, accelerate the additional speed of burning indoor oxygen, helped the abundant burning of fuel, saved fuel, alleviated the harm of flue dust, reduced because of the pollution level of imperfect combustion to atmosphere to human body.
Below in conjunction with accompanying drawing reversing smoke free blast cap described in the utility model further is described in detail.
Fig. 1 is the upright hat type schematic diagram of existing anti-down cigarette blast cap;
Fig. 2 is the upright three way type schematic diagram of existing anti-down cigarette blast cap;
Fig. 3 be existing anti-down cigarette blast cap keep flat the hat type schematic diagram;
Fig. 4 is threeway (cap) formula that the keeps flat schematic diagram of existing anti-down cigarette blast cap;
Fig. 5 is a reversing smoke free blast cap partial cutaway vertical view described in the utility model;
Fig. 6 is that the A-A of reversing smoke free blast cap shown in Figure 5 is to cutaway view.
With reference to Fig. 5, Fig. 6, the curved slab 2 that keeps out the wind on the reversing smoke free blast cap is narrow with the centre that the curved slab 3 that keeps out the wind down forms, 4 dividing plates 1 are set in the space layer of Zhou Biankuan equably, to go up, under the curved slab that keeps out the wind be connected as a single entity, and this space layer is separated into 4 funnel-form ventilating ducts, on the circular hole that chimney plug 6 is connected down in the middle of the curved slab 3 that keeps out the wind and the chimney plug is isometrical, 4 ends that support battens 4 with under the curved slab 3 that keeps out the wind be connected, the other end that supports batten 4 is " U " type, dead ring 5 is stuck in gripper shoe 4 " U " the type groove, respectively there is an aperture at the two ends of dead ring 5, the aperture that screw 7 passes on the binding 5 is connected with nut 8, lowest part at the last curved slab 2 that keeps out the wind has two little dewatering orifice M1 symmetrically, M2, like this, rainwater will along on keep out the wind curved slab 2 through curved slab 3 outflows of keeping out the wind down, avoid because of accumulating rainwater curved slab 2 corrosions of keeping out the wind on causing.
The end that chimney plug 6 is connected with chimney has several slits, can pass through dead ring 5, screw 7 and nut 8 as required and adjust its breathing, is connected reliably to reach with the chimney of multiple diameter.

Claims (2)

1, a kind of reversing smoke free blast cap, it is characterized in that: in the space layer of, Zhou Biankuan narrow with the centre that the curved slab (3) that keeps out the wind down forms some dividing plates (1) are being set equably at the last curved slab that keeps out the wind (2), the upper and lower curved slab that keeps out the wind is connected as a single entity, on the circular hole that chimney plug (6) is connected down in the middle of the curved slab that keeps out the wind (3) and the chimney plug is isometrical, one end of plurality of support (4) with under the curved slab (3) that keeps out the wind be connected, the other end links to each other with chimney plug (6) by dead ring (5).
2, according to the described reversing smoke free blast cap of claim 1, it is characterized in that: dividing plate (1) is 4, the end that chimney plug (6) links to each other with chimney has the slit, on the keep out the wind lowest part of curved slab (2) have the dewatering orifice, gripper shoe (4) is 4, the two ends of dead ring (5) have aperture, and the aperture that screw (7) passes on the binding (5) is connected with nut (8).
