Description

Technical Field

[0001] The utility model relates to a fresh air controller, in particular to a fresh air controller with a protective structure. Background Art

[0002] The fresh air fan is an effective air purification device that can circulate indoor air. On the one hand, it discharges the polluted air indoors to the outside, and on the other hand, it inputs the fresh air outdoors into the room after sterilization, disinfection and filtration, so that the room is filled with fresh and clean air at all times. The fresh air controller is the intelligent control device of the fresh air fan.

[0003] The fresh air controller includes a control base box and a control screen, which are generally installed on the wall. At present, the fresh air controller basically uses the control screen to control the fresh air fan. If the control screen is hit during normal use, it is easy to cause damage. For example, when carrying items, if the items collide with the control screen by accident, the control screen will be damaged. Once damaged, the control screen cannot be used. If the control screen cannot be used, the operator cannot operate the fresh air fan and can only replace it. Therefore, a fresh air controller with a protective structure is proposed.

[0017] Next, we will further explain the fresh air controller with a protective structure described in the present invention in conjunction with the accompanying drawings.

[0018] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0019] In the present invention, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense; for example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] See also Figure 1-4 As shown in the figure, a fresh air controller with a protective structure includes a control base box 1 and a control screen 2 installed on the control base box 1; it is characterized in that it also includes a protective structure arranged on the control base box 1 for protecting the control screen 2, the protective structure includes a protective shell 3 slidably installed on the control base box 1, the control base box 1 is provided with a slide groove 11 for guiding the movement of the protective shell 3, and the two sides of the protective shell 3 are provided with sliders 31 adapted to the slide groove 11;

[0021] The protection structure is provided to protect the control panel 2, thereby preventing the control panel 2 from being damaged by accidental collision when carrying items or other situations, thereby increasing the service life;

[0022] The slide groove 11 and the slider 31 are provided to limit and guide the movement of the protective shell 3 on the control base box 1.

[0023] In one embodiment, it also includes an elastic switch 4 arranged on the control base box 1 and the protective shell 3 for limiting the position of the protective shell 3; through the setting of the elastic switch 4, the position of the protective shell 3 on the control base box 1 is limited, including the limit when the protective shell 3 is opened and closed. When operating the control screen 2, there is no need to hold the protective shell 3 with one hand to avoid the problem of interference with the operation of the control screen 2 due to the falling of the protective shell 3.

[0024] In one embodiment, the elastic switch 4 comprises a mounting slot 41 provided on the control bottom box 1, a locking block 42 slidably installed in the mounting slot 41, a baffle 43 installed at the rear side of the mounting slot 41, a spring 44 installed in the mounting slot 41 and between the locking block 42 and the baffle 43, and a top block 5 slidably installed on the protective shell 3;

[0025] The locking block 42 is also provided with a contact end 45, which penetrates the control bottom box 1 and contacts the top block 5;

[0026] When the elastic switch 4 locks the protective shell 3, the elastic force of the spring 44 pushes the locking block 42 forward, so that the contact end 45 on the locking block 42 extends out of the control base box 1 and partially enters the T-shaped groove of the protective shell 3 to define the position of the protective shell 3 on the control base box 1. The contact end 45 enters the T-shaped groove of the protective shell 3 and pushes the top block 5 forward at the same time, so that the protruding end of the top block 5 extends out of the protective shell 3.

[0027] In one embodiment, the top block 5 is arranged in a T-shape, and a T-slot 51 adapted to the top block 5 is provided on the protective shell 3; by setting the top block 5 in a T-shape and providing a T-slot 51 on the protective shell 3, the movement of the top block 5 in the protective shell 3 is limited, thereby preventing the top block 5 from escaping from the protective shell 3.

[0028] In one embodiment, a guide slope 52 is further provided on the contact end 45; through the setting of the guide slope 52, when the protective shell 3 moves downward, the bottom of the protective shell 3 contacts the contact end 45 and pushes the locking block 42 to move inward along the guide slope 52, thereby preventing the locking block 42 from interfering with the movement of the protective shell 3.

[0029] When the utility model is in use: when opening the protective shell 3, the operator presses the top blocks 5 on both sides with his fingers, and the top blocks 5 push the contact ends 45 to move inwards, and the contact ends 45 drive the locking blocks 42 to move inwards and squeeze the springs 44. At this time, the contact ends 45 retract into the control bottom box 1, and then the operator keeps pressing the top blocks 5 while pushing the protective shell 3 upwards, and the protective shell 3 moves upwards along the slide slots 11. At this time, the top blocks 5 can be released, and when the protective shell 3 moves upwards, the top blocks 5 are driven to move to the position of the locking blocks 42 on the upper side, and the locking blocks 42 are pushed forward by the elastic force of the springs 44, and the locking blocks 42 drive the contact ends 45 to extend out of the control bottom box 1 into the T-slots 51 and squeeze the top blocks 5, so that the protruding end of the top blocks 5 protrudes out of the protective shell 3. At this time, the position of the protective shell 3 is locked, and the operator can operate the control screen 2;

[0030] When closing the protective shell 3, the operating heat source presses the top blocks 5 on both sides at the same time again in the same way, and then drives the protective shell 3 to move downward. During the downward movement of the protective shell 3, the bottom of the protective shell 3 contacts the contact end 45 on the lower side, and the contact end 45 is pushed inward along the guide slope 52 during the continuous downward pushing process. After the top block 5 is in the locking block 42, the spring 44 drives the contact end 45 to extend out of the control bottom box 1 to be in the T-slot 51, and at the same time pushes the protruding end of the top block 5 to protrude out of the protective shell 3, and the closing of the protective shell 3 is completed at this time.

[0031] The protection scope of the present utility model is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present utility model.
