Description

Every the glass type ventilation fan

The utility model relates to ventilation equipment, especially the room ventilation air regenerating device.

As the room ventilation air regenerating device, ventilation fan is simple in structure small and exquisite, cheap for manufacturing cost with it, ventilation effect is favored by people well and quite, and it is installed in the place that kitchen, toilet, parlor, computer room etc. need ventilation, for people create a living environment with fresh air.Ventilation fan is made up of protecgulum, master frame, impeller, bonnet etc., the bonnet of general ventilation fan is a venetian blind, open and close by blast and the control of other method, the structure that a kind of bonnet openable is also arranged, bonnet is hinged on the master frame, open and close by backguy control, the backguy knotting is stuck in the groove of master frame, the position of " knot " in the backguy must be very accurate, otherwise cause that easily bonnet closes tight or be difficult to close, and the big palpulus of " knot " is suitable, too small just card incessantly, also to increase by one " tiltedly drawing " action during operation, very sense inconvenience, and appearance and modeling is unsatisfactory.

The purpose of this utility model is to overcome the defective of prior art and provides a kind of easy and simple to handle, bonnet to open and close freely, close firm is first purpose every the glass type ventilation fan; It is second purpose that a kind of appearance and modeling ventilation fan attractive in appearance is provided.

The purpose of this utility model realizes by following technical proposal: comprise protecgulum fastened to each other and master frame, master frame internal fixation has the motor of band sensitive switch, fixing impeller on the output shaft of motor, bonnet is connected with torsion spring by inserting of both sides with the master frame, torsion spring acts on the bonnet inwall makes it have opening force, the bonnet inwall is provided with the projection that is cut-off by backguy control power supply at the corresponding site at sensitive switch, it is characterized in that being provided with between described bonnet and the master frame lock construction that opens and closes bonnet, it comprises and is arranged on the bonnet inwall, both sides have the dead bolt and the door lock of relative set in the master frame of recessed circular groove, door lock comprises and has the lock body of buckleing lobe, it snaps in the hole slot of master frame by the button lobe, be provided with in the lock body by dead bolt and promote can slide up and down, have the slide block that clamps spring, there is a cross groove slide block below, be provided with steel ball in the groove, be provided with stage clip below the slide block, the cover plate inwall of sealing lock body has the triangular cam chute that the steel ball clockwise direction slides, and has the steel ball locating slot in the middle of the chute.

The moulding of circle rear, arc transition before the profile of protecgulum adopts is to increase overall appearance.

The utility model has the advantages that: the directly keying of control lock structure of pulling backguy, draw, bonnet is opened, and the running of ventilation fan electric motor starting is drawn again, the ventilation fan stall, bonnet is closed auto lock, need not tiltedly spur work, and is easy and simple to handle, opens and closes freely; Rationally lock construction is closed firmly bonnet reliably, has avoided backguy to beat " knot " existing all disadvantages.

Remake below in conjunction with above-mentioned accompanying drawing embodiment and to elaborate.

Shown in Fig. 1～7, directly be inlaid on the Window Glass every the glass type ventilation fan, so be named it, it comprises protecgulum fastened to each other (1) and master frame (2), the protecgulum profile is preceding round rear, and arc transition.The downside of protecgulum has a backguy breach (5).

Master frame (2) internal fixation has the motor (7) of band sensitive switch (10), and motor is inlaid in the muscle seat (8), is fixing impeller (6) on its output shaft, also is provided with inserting (11) and the door lock (9) of the bonnet that locks of location bonnet on the master frame.

Bonnet (3) is made by transparent plastic, its both sides, top have little axle (12) can be shelved in the groove of insert (11), and form with torsion spring (16) and to be rotatably connected, torsion spring one end acts on master frame inwall, one end interts the hole slot of bonnet and acts on the inwall, the effect that bonnet is connected and can not break away from automatically because of torsion spring makes bonnet have opening force, the bonnet inwall is provided with the projection (13) that is cut-off by backguy (4) control power supply at the corresponding site at sensitive switch, the bottom is provided with the dead bolt (14) and the backguy seat (15) of closing bonnet and auto lock, one end ligation of backguy (4) is on the backguy seat, and the other end is drawn by the backguy breach (5) of protecgulum through the master frame.

Be provided with lock construction between bonnet and the master frame, it comprises the dead bolt (14) that is located at the bonnet inwall, and the dead bolt both sides have recessed circular groove.The corresponding door lock (9) that is provided with in the master frame, door lock comprise and have the lock body (18) of buckleing lobe (20), and the button lobe is to snap in the master frame hole slot usefulness that is located by connecting.Be provided with in the lock body by dead bolt and promote can slide up and down slide block (19), two clamped spring (17) about slide block had, recessed circular groove on clamping spring and the dead bolt matches and promptly is locked, there is a cross groove (23) the slide block below, be provided with sheet spring (27) and steel ball (22) in the groove, be provided with the stage clip (21) of the usefulness that resets in the following and lock body of slide block at the end, in cover plate (25) is enclosed in other part in the lock body, the cover plate inwall has the triangular cam chute (24) that steel ball slides, this chute degree of depth from shallow to steel ball (22) can only be slided in the direction of the clock, the locating slot (26) of doing the steel ball location is arranged in the middle of the chute, be recessed circle.
