Abstract
A variable-air-output dustproof ventilating fan belongs to the technical field of ventilating equipment and is used for indoor-outdoor ventilation. According to the technical scheme, the variable-air-output dustproof ventilating fan comprises a ventilating fan frame, fan blades, fan blade cover, blind baffles and a seal cover. The seal cover is a square board with a perpendicularly-downward peripheral circular edge. The seal cover is provided with a round hole at the center. The diameter of the round hole is equal to that of each fan blade. The rim of the circular edge is detachably connected with the fan blade cover. The upper portion and the lower portion of the surface of the seal cover are provided with transverse clamping grooves respectively, and seal sheets capable of moving left and right are inserted into the clamping grooves. By the aid of the seal cover added to the ventilating fan, the seal sheets can be closed to seal the fan blade side of the ventilating fan and prevent dust entry. The seal sheets can be adjusted in the clamping grooves to adjust volume of air blown by the fan blades. The seal cover is detachably connected the ventilating fan and can be taken down and mounted conveniently. The variable-air-output dustproof ventilating fan is simple in structure, convenient to use and low in cost and has the functions of air input adjusting and dust proofing.
Description
Technical field
The utility model relates to a kind of ventilation fan that can carry out the indoor and outdoor ventilation, belongs to the air regenerating device technical field.
Background technology
In commercial production and daily life, carry out indoor and outdoor ventilation and be keeping indoor air clean, fresh requisite measure.Particularly in indoor environment because activity in production dust is more, more need at any time pernicious gas to be discharged to outdoor when perhaps producing some pernicious gases, introduce outdoor live gas indoor, carry out air exchange, with the health of assurance human body.At present, general ventilation fan generally can carry out two-way air draft, both can discharge air, also can use easily to indoor blowing.The outside of this ventilation fan also has the blinds baffle plate simultaneously, and the blinds baffle plate hangs down when ventilation fan does not start, and prevents dust, mosquitos and flies etc. through in the flabellum place inlet chamber, and the blinds baffle plate is opened when ventilation, lets air pass through.But find that in use this ventilation fan also has some shortcomings, the one, the dustproof effect of blinds baffle plate is not ideal enough, still has in the dust inlet chamber; The 2nd, the intake of ventilation fan is unadjustable, and this shortcoming needs less air quantity show obviously especially to indoor introducing air the time.At present, it is to change motor speed through arrangements for speed regulation that general electric fan is regulated air quantity, reaches the effect of regulating air quantity.If ventilation fan also adopts this method, just need to increase cover arrangements for speed regulation, therefore can increase the cost of ventilation fan.But the price of general ventilation fan is very low, and particularly the low power ventilation fan turnover rate of family's use is very high, and the price of the price of ventilation fan being brought up to the common electrical fan obviously is worthless.Therefore be necessary to design and a kind ofly both can keep cheap price, can regulate the ventilation fan of intake simultaneously again, to satisfy the needs in market.
The utility model content
The utility model technical problem to be solved provides a kind of good dustproof effect, intake and can regulate, cheap can regulate intake and dustproof ventilation fan.
The technical scheme that solves the problems of the technologies described above is:
A kind ofly can regulate intake and dustproof ventilation fan, it comprises ventilation fan framework, flabellum, flabellum cover, blinds baffle plate, and flabellum is installed on the ventilation fan framework; It is inboard that the flabellum cover is installed in the ventilation fan framework, and the blinds baffle plate is installed in the outside of ventilation fan framework, and its improvements are; It has also increased seal closure, and seal closure is a square plate, and periphery has annular edge vertically downward; The center of seal closure is a circular hole, and the diameter and the flabellum of circular hole are complementary, and the edge of annular edge and flabellum cover are for removably connecting; The both sides up and down on seal closure surface have horizontal draw-in groove respectively, but are inserted with the diaphragm seal of move left and right in the draw-in groove.
Above-mentionedly can regulate intake and dustproof ventilation fan; The upper and lower of said flabellum cover is flexible card respectively; Elastic card and the stressed joint of seal closure edge card; Or the both sides of flabellum cover are fixed with small magnet, are fixed with iron plate on the annular edge of seal closure, and the position of iron plate is corresponding with the position of small magnet.
Above-mentionedly can regulate intake and dustproof ventilation fan, the said diaphragm seal that is inserted in the seal closure draw-in groove is two, lays respectively at the both sides of seal closure, and the last lower limb of diaphragm seal is embedded in the draw-in groove, and the outward flange of diaphragm seal has the flanging that upwards bends.
The usefulness of the utility model is:
After having increased seal closure on the ventilation fan, close the sealing that diaphragm seal just can be realized flabellum one side of ventilation fan, prevent that dust from getting into; Regulate the left and right sides position of diaphragm seal in draw-in groove and can regulate the air quantity that flabellum is blown into; Seal closure and ventilation fan can take off and install for removably connecting easily.The utility model is simple in structure, easy to use, cheap, has the intake of adjusting and dustproof function simultaneously.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the side view of the utility model;
Fig. 3 is the vertical view of the utility model.
Mark is following among the figure: ventilation fan framework 1, flabellum 2, flabellum cover 3, blinds baffle plate 4, seal closure 5, annular edge 6, elastic card 7, diaphragm seal 8, draw-in groove 9, flanging 10.
The specific embodiment
The utility model is made up of ventilation fan framework 1, flabellum 2, flabellum cover 3, blinds baffle plate 4, seal closure 5.Flabellum 2 is installed on the ventilation fan framework 1, and flabellum cover 3 is installed in the inboard of ventilation fan framework 1, and blinds baffle plate 4 is installed in the outside of ventilation fan framework 1, and this structure is identical with general ventilation fan, and its improvements are to have increased seal closure 5.
Show among the figure that seal closure 5 is a square plate, make by plastic plate or iron sheet.The center of seal closure 5 is a circular hole, and the diameter of circular hole and flabellum 2 are complementary, and can let air from circular hole, pass.The square plate periphery of seal closure 5 has annular edge 6 vertically downward, and the edge of annular edge 6 and flabellum cover 3 are for removably connecting.Connected mode has multiple, and wherein a kind of is that elastic card 7 connects, and promptly flexible card 7 is distinguished in the upper and lower of flabellum cover 3, and elastic card 7 blocks clamping with seal closure 5 two ends; It can also be magnet pasting; Promptly both sides or the upper and lower side at flabellum cover 3 is fixed with small magnet, is fixed with iron plate on the annular edge 6 of seal closure 5, and iron plate adsorbs with small magnet mutually; If seal closure 5 adopts iron sheet to make with annular edge 6, then annular edge 6 just can directly be inhaled with small magnet mutually.
