Description
Technical field
The utility model relates to pipe ventilated technical field, in particular to a kind of modified rainhat.
Background technique
Currently, with the development of industry, also more frequent for the use of ventilation field, some ventilation shafts need to carry out
Still after going out roofing due to pipeline, there is roof leaking in outdoor air draft, cause to corrode to pipeline inside, pipeline is caused to use
Service life is reduced, and the rainhat of traditional handicraft easily leads to corrosion inside pipeline there are numerous roof leaking hidden danger.For this purpose, needing to existing
Rainproof hat for exhaust duct improve.Such as China Patent No.: CN201320425695.9 discloses a kind of exhaust duct use
Rainhat solves the problems, such as that existing apparatus water blocking effect is poor, the Rainproof hat for exhaust duct include cooperation rainhat top,
Rainhat lower part, the rainhat top and rainhat lower part are mutually matched cone cylinder；It is equipped with water-collecting tray in rainhat, catchments
Pan bottom is equipped with the drainpipe led to outside rainhat；Rainhat lower base is socketed in outside water blocking short tube, and water blocking short tube protrudes into anti-
In rain cap lower part, catch basin is formed between water blocking short tube and rainhat lower part, the row of being equipped on the rainhat lower part wall of catch basin
Water hole.But its upper opening is easy to be blown into rainhat upper inside wall and then fair current to pipeline because of rainwater inclination, while rain-proof
Cap upper opening also has that water goes downstream along inner wall, so that the rainhat waterproof effect is undesirable, using depositing
In defect, there are water inlet hidden danger.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes it is a kind of it is simple and reasonable, water blocking air permeability effect is good, dimension
Protect modified rainhat easy to use.
To solve this technical problem, the utility model takes following scheme: a kind of modified rainhat, including is up and down
It is open and in the upper housing and lower case, water-collecting tray and drainpipe of cone barrel, the big disc opening of the upper housing and lower case
Cooperate connection, support frame is equipped in the lower case, the water-collecting tray is set on support frame and pan bottom of catchmenting is equipped with row
The mouth of a river, described drainpipe one end are connected with the discharge outlet of water-collecting tray, and the free end of the drainpipe, which tilts down, is pierced by lower casing
Body is drained, and it is equal up and down that the upper housing top opening extends composition in the middle part of upper housing towards central axis inwardly downward
For the trapezoidal cylinder wide at the top and narrow at the bottom of opening, the opening bore of the trapezoidal cylinder is less than the upper opening bore of water-collecting tray.
Further to improve, further include is the waterproof and breathable film layer of trapezoidal tubular of being open, the waterproof and breathable up and down
Film layer lower end is sheathed on water-collecting tray upper opening, and waterproof and breathable film layer top extends to inner wall or extension in the middle part of upper housing
To the trapezoidal cylinder lower part of cladding.
Further to improve, the lower case bottom opening extends downwardly composition connecting tube, on the free end of the connecting tube
It is connected equipped with flange and by flange with exhaust pipe.
By using preceding solution, the beneficial effects of the utility model are: by prolonging in upper housing opening setting one
The opening bore for extending to the trapezoidal cylinder in the middle part of upper housing, and trapezoidal cylinder being arranged is less than the opening bore of water-collecting tray, so that rainwater
When inclination is blown into upper housing upper inside wall along trapezoidal cylinder inner wall fair current to water-collecting tray, while the water of upper housing upper opening inner wall
Also it can go downstream along trapezoidal cylinder inner wall to water-collecting tray, water is effectively avoided to enter the water inlet hidden danger of exhaust pipe, waterproof effect
It is good, while not influencing to be vented, by being further arranged, i.e. the setting of waterproof and breathable film layer, so that the water inlet of upper housing opening
Completely into being discharged in water-collecting tray, while the vented exhaust function of entire rainhat is not influenced, further increase entire rainhat
Performance, structure is simple, safeguard it is easy to use, can wide popularization and application.
Detailed description of the invention
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
With reference to Fig. 1, the modified rainhat of preferred the utility model, including being up and down opening and being in the upper of cone barrel
Shell 1 and lower case 2, water-collecting tray 3, drainpipe 4 and waterproof and breathable film layer 5, the upper housing 1 and the big disc of lower case 2 are opened
Mouth, which cooperates, to be connected, and is equipped with support frame 6 in the lower case 2,2 bottom opening of lower case extends downwardly composition connecting tube
21, the free end of the connecting tube 21 is equipped with flange 22 and is connected by flange 22 with exhaust pipe, and the water-collecting tray 3 is set to
On support frame 6 and 3 bottom of water-collecting tray is equipped with discharge outlet, and the 3 bottom discharge mouth of water-collecting tray is connected with drainpipe 4, the row
The free end of water pipe 4, which tilts down, to be pierced by lower case 2 and is drained, and 1 top opening of upper housing is inside towards central axis
Extend downwardly the trapezoidal cylinder 11 wide at the top and narrow at the bottom that composition in the middle part of upper housing is opening up and down, the opening mouth of the trapezoidal cylinder 11
Diameter is less than the upper opening bore of water-collecting tray 3, and it is the trapezoidal tubular moulding of opening, institute that the waterproof and breathable film layer 5, which is upper and lower,
It states 5 lower end of waterproof and breathable film layer to be sheathed on 3 upper opening of water-collecting tray, 5 top of waterproof and breathable film layer extends to upper housing 1
Middle part inner wall extends to the trapezoidal cylinder lower part of cladding.
Waterproof and breathable film layer top also may extend to the trapezoidal cylinder lower part setting of cladding and also may be used in the utility model.
The utility model is arranged trapezoidal by extending to the trapezoidal cylinder in the middle part of upper housing in upper housing opening setting one
The opening bore of cylinder is less than the opening bore of water-collecting tray, so that along trapezoidal cylinder inner wall when rainwater inclination is blown into upper housing upper inside wall
In fair current to water-collecting tray, while the water of upper housing upper opening inner wall can also go downstream along trapezoidal cylinder inner wall to water-collecting tray, have
The water inlet hidden danger for avoiding water from entering exhaust pipe imitated, good water-proof effect, while not influencing to be vented, by being further arranged,
That is the setting of waterproof and breathable film layer so that the water inlet of upper housing opening is in water-collecting tray completely into being discharged, while not influencing entire
The vented exhaust function of rainhat, further increases the performance of entire rainhat, and structure is simple, and maintenance is easy to use, can be extensive
It promotes and applies.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
