Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides an embodiment:

the utility model provides a fresh air handling unit with insulation construction prevents frostbite, includes chassis body 1, and chassis body 1's front fixed mounting has control panel 2, and chassis body 1's left side fixed mounting has out tuber pipe 3, and chassis body 1's right side fixed mounting has air-supply line 4, and chassis body 1's bottom all evenly articulates there is hinge bar 13, and the quantity of a set of hinge bar 13 is two.

The right-hand member of air-supply line 4 cup joints installs filter screen 5, and the quantity of filter screen 5 is two, utilizes filter screen 5 to carry out the first time with a large amount of dust of outside and filters, because the change of the inside filtration of machine case main part 1 washs too troublesome, increases the life of inside filtration through the filtration of filter screen 5, reduces the change and the washing to inside filtration, and the work loaded down with trivial details degree that the staff saves labour.

All movable mounting has mounting structure 8 in the mounting hole 9 on two filter screens 5, the equal fixed mounting in one side of filter screen 5 inside has slide rail 11, slide rail 11 inscription slidable mounting has slider 7, one side fixed mounting that two sliders 7 are close to each other has sealing plug 6, the one end fixed mounting of sealing plug 6 has first pull ring 12, when this fresh air unit that has the insulation structure that prevents frostbite passes through control panel 2 stop work, inwards push away first pull ring 12 and make sealing plug 6 plug up air-supply line 4, prevent outside cold wind to enter into the inside that has the fresh air unit of the insulation structure that prevents frostbite, and then play and prevent that the heater pipeline from being split and the heat preservation effect to inside.

The front and the back of filter screen 5 all fixed mounting have mounting panel 10, mounting hole 9 has all been seted up on mounting panel 10, mounting hole 9 comprises a cross-cut hole and a spacing groove, cross-cut hole and spacing groove through mounting hole 9 mutually support with mounting structure 8, second pull ring 81 through the tensile upside of mounting structure 8 with mounting hole 9 inside makes limiting plate 82 remove spacing groove in the middle of rotatory messenger limiting plate 82 and the parallel second pull ring 81 of pulling down the downside of cross-cut hole can take out mounting structure 8 and dismantle and wash filter screen 5.

Mounting structure 8 includes second pull ring 81, limiting plate 82, reset spring 83 and third telescopic link 84, and the upper and lower both ends of third telescopic link 84 are all fixed mounting has limiting plate 82, and the equal fixed mounting in one side that two limiting plates 82 kept away from each other has second pull ring 81, and reset spring 83 has been put to the outside cover of third telescopic link 84, and mounting structure 8's simple structure, the mounting means is swift to the firm of connection installation of little structure.

All fixed mounting have the second telescopic link 18 in the middle part of a set of hinge bar 13, first buffer spring 15 has all been set in the second telescopic link 18 outside, hinge bar 13's bottom slidable mounting has buffering bottom plate 14, the all fixed mounting in both sides of 1 bottom of machine case main part has first telescopic link 17, second buffer spring 16 has been set in the outside cover of first telescopic link 17, and the bottom of first telescopic link 17 is installed on buffering bottom plate 14, because the too big long-time vibrations of vibrations that the centrifugal fan produced of heater pipeline by the frost crack inside can damage the part of 1 insides of machine case main part not hard up, prevent the condition that the part dropped through the fastening that is provided with buffer structure protection internals, influence the life of device.

The working principle is as follows: when the fresh air handling unit with the anti-freezing and heat-insulating structure is used in winter, firstly, the sealing plug 6 at the rear side of the air inlet pipe 4 is pulled out through the first pull ring 12, the device is opened through the control panel 2 to work, when the dust on the filter screen 5 is too much due to long-term work, the mounting structure 8 can be taken out to disassemble and clean the filter screen 5 by pulling the second pull ring 81 at the upper side by stretching the mounting structure 8 in the mounting hole 9 to remove the limiting plate 82 from the limiting groove to rotate so that the limiting plate 82 is parallel to the transverse through hole and the second pull ring 81 at the lower side is pulled downwards, parts in the case body 1 can be damaged and loosened due to overlarge vibration generated by a centrifugal fan in a frost crack of a heater pipeline for a long time, the tightness of the parts in the case body can be protected by the buffering structure to prevent the parts from falling, the service life of the device is influenced, and when the fresh air handling unit with the anti-, the first pull ring 12 is pushed inwards to enable the sealing plug 6 to block the air inlet pipe 4, so that external cold air is prevented from entering the interior of the fresh air handling unit with the anti-freezing and heat-insulating structure, the functions of preventing a heater pipeline from being frozen and insulating the interior are achieved, the filter screen 5 is arranged, a large amount of external dust is filtered for the first time by the filter screen 5, due to the fact that the filter structure inside the case main body 1 is troublesome to replace and clean, the service life of the internal filter structure is prolonged through the filtering of the filter screen 5, the replacement and cleaning of the internal filter structure are reduced, the work complexity of labor personnel is saved, when the fresh air handling unit with the anti-freezing and heat-insulating structure stops working through the control panel 2, the first pull ring 12 is pushed inwards to enable the sealing plug 6 to block the air inlet pipe 4, and the external cold air is prevented from entering the interior of the fresh air handling unit with the anti-freezing and heat-insulating structure, and then play and prevent that the heater pipeline from being split by the frost and the heat preservation effect to inside, through being provided with mounting structure 8 and mounting hole 9, make limiting plate 82 remove the second pull ring 81 of the tensile upside of mounting structure 8 inside mounting hole 9 and rotate in the middle of the spacing groove through making limiting plate 82 and the second pull ring 81 that the cross-cut hole is parallel to in the downside that pulls down and can take out mounting structure 8 and dismantle and wash filter screen 5.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
