Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 6, the window sash convenient to adjust comprises a housing, fan blades 7 and a motor 9, wherein the fan blades 7 are driven by the motor 9, the housing is provided with air inlets 3.5 for air inlet and air outlet, and the fan blades 7 are arranged in an air duct which leads from one air inlet 3.5 to the other air inlet 3.5 in the housing. The casement still includes flexible subassembly 14, at least one end of casing is equipped with the confession the opening that flexible subassembly 14 passed, and is preferred, and both ends all are equipped with the opening about the casing, the inside locating part 3.2 that is equipped with of opening. The telescopic assembly 14 comprises a moving member 4 and a telescopic plate 13, the moving member 4 is slidably arranged in the shell, the inner end of the telescopic plate 13 is fixed in the shell, and the other end of the telescopic plate is fixed on the moving member 4; the moving piece 4 is provided with sawtooth structures 4.1 distributed along the extending and contracting direction, and the sawtooth structures 4.1 can form limiting matching with the limiting piece 3.2 to adjust the moving distance of the moving piece 4.

When using, if the window frame size is great, then outwards pull out moving member 4 can, at the pull-out in-process, the tip of locating part 3.2 forms sliding fit with sawtooth structure 4.1's inclined plane, consequently makes outwards pulling out that moving member 4 can relax. When the moving member 4 stops moving, the stop surface of the sawtooth structure 4.1 and the limiting member 3.2 form limiting constraint, and the moving member 4 cannot be easily retracted inwards at this time. When needs retract the moving member 4 into the casing, only need hit the outer end of moving member 4 hard, because the casing is made for the plastics material, consequently has certain elastic deformation ability, thereby the spacing restraint between sawtooth structure 4.1 and the locating part 3.2 takes place to break away from and makes the moving member 4 retract in to the casing under great exogenic action this moment. At the in-process of moving member 4 outside removal, because expansion plate 13 is because one end is fixed, one end removes, consequently expandes gradually along with moving member 4 receives the tractive of moving member 4 and in order to adapt to the requirement of size change, and expansion plate 13 can be the stereoplasm plate body that has beta structure, also can be the soft plate body that has deformability, as long as satisfy can play the effect of the interior outer space of isolation window frame and move along with moving member 4 and the requirement of size change can.

In order to improve the firmness of the telescopic assembly 14 and avoid the phenomenon of looseness under the effect of multiple times of telescopic action, the telescopic assembly 14 comprises two moving members 4, and the upper side and the lower side of the outer end of the telescopic plate 13 are fixedly connected with the outer ends of the two moving members 4 through bolts. The two moving members 4 are slidably disposed at the top and the bottom of the housing, respectively.

In order to enable the moving member 4 to move along a straight line, a sliding groove 3.1 for the sliding installation of the moving member 4 is arranged in the shell. The moving member 4 is a strip-shaped structure, and thus can be used as a frame. The sawtooth structure 4.1 is provided on the front or rear side of the moving member 4.

In order to facilitate manufacturing and mounting of internal components, the shell comprises two parts with the same structure, the shell comprises two split bodies 3 which are fixedly connected front and back through screws 2 to form an internal accommodating space, and the surface of each split body 3 is provided with at least one air opening 3.5, preferably two symmetrical air openings 3.5 to improve ventilation. The left end and the right end of the split body 3 are respectively provided with a notch 3.6, after the two split bodies 3 are connected, the two notches 3.6 on the same side form the opening, and the inner wall of the split body 3 is provided with the limiting part 3.2. Similarly, the chute 3.1 is also formed by the crosspiece and its peripheral side rail members inside the split body 3.

In order to facilitate carrying of the window sash, a handle part 3.4 for being gripped by hands is formed on the shell, and the specific forming mode of the handle part 3.4 is as follows: the top of the split body 3 is also provided with a hollow-out part 3.3 and a handle part 3.4 formed by the hollow-out part 3.3.

Because the formation of fretwork portion 3.3 has produced great space, consequently for the optimal arrangement, the casing is in the bottom of fretwork portion 3.3 is equipped with adjust knob 6, be equipped with controller 5 and temperature controller 15 in the casing, controller 5 locates the inside top of casing, and temperature controller 15 locates the central authorities in the casing. As shown in fig. 6, the controller 5 is electrically connected to the motor 9, the temperature controller 15 is electrically connected to the controller 5, and the adjusting knob 6 is connected to the controller 5 to control the start/stop and the rotation speed of the motor 9; when the room temperature is lower than the set value of the temperature controller 15, the temperature controller 15 outputs a speed reduction signal or a stop signal to the motor 9, and when the room temperature is higher than the set value of the temperature controller 15, the temperature controller 15 outputs a speed increase signal or a start signal to the motor 9. The whole power supply of the window sash is realized by connecting a power line and a plug 12 into commercial power.

The number of the air ports 3.5 on the split body 3 is two, and the number of the motor 9 and the number of the fan blades 7 are also two.

The size of components of a whole that can function independently 3's horizontal direction is greater than its vertical direction's size, and whole casing is the cuboid structure, and length direction's both ends are located to the opening.

In order to fix and protect the motor 9, the window sash further comprises a motor casing 10, the motor casing 10 is fixed in the casing through a screw 11, and the motor 9 is fixedly accommodated in the motor casing 10.

In order to meet the requirement that the window sash is used indoors, the bottom of the shell is also provided with a base 1, the window sash is taken down from a window frame, and the window sash can be placed on the plane such as the ground, a table top and the like after the base 1 is installed.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
