[0002] A fresh air air conditioner is an air conditioner with a fresh air system function. The fresh air system refers to an indoor air circulation system and an outdoor air circulation system, the fresh air system. The main function of the fresh air system of an air conditioner is to achieve the circulation and ventilation of indoor air and outdoor air, and also has the function of purifying air. By discharging the turbid air in the room to the outside through the fresh air system pipeline, an indoor and outdoor air pressure difference is formed to complete the air exchange between indoor and outdoor. All fresh air air conditioners are equipped with special fresh air controllers to control the core components to achieve temperature adjustment and air flow conversion.

[0003] The existing air conditioner fresh air controller lacks a mechanism that can effectively protect the screen and buttons on the panel. When used in an environment with children, it causes children to easily operate the buttons or screen on the panel of the air conditioner fresh air controller out of curiosity, resulting in the change of the temperature or air outlet mode originally set by adults. Sometimes, even the screen or buttons are damaged due to violent operation by children.

[0004] Therefore, it is necessary to provide a new fresh air controller for an air conditioner with a protection mechanism to solve the above technical problems. Content of the Utility Model

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and implementation manners.

[0027] Please refer to Figures 1 - 8 , where Figure 1 is the schematic diagram of a preferred embodiment of an air conditioner fresh air controller with a protection mechanism provided by the present utility model; Figure 2 For Figure 1 Enlarged schematic diagram of part A shown; Figure 3 For Figure 1 Enlarged schematic diagram of part B shown; Figure 4 For Figure 1 Exploded schematic diagram of the protective cover shown; Figure 5 Schematic diagram of the structure of the air conditioner fresh air controller with a protection mechanism provided by the present utility model after removing the cover plate;Figure 6 is Figure 5 the enlarged schematic view of part C shown in Figure 7 is Figure 5 the structural schematic view of the protective box shown in Figure 8 is Figure 7 the exploded schematic view of the protective box shown in. The air conditioner fresh air controller with a protection mechanism includes: the air conditioner fresh air controller body 1, and the composition of the air conditioner fresh air controller body 1 adopts the conventional design of the existing technology air conditioner fresh air controller. Two fixing blocks 2 are fixedly installed on the panel of the air conditioner fresh air controller body 1 and close to the top position. Fixed shafts 3 are fixedly installed on the outer walls of the two fixing blocks 2 close to each other. Connecting blocks 4 are rotatably sleeved on the two fixed shafts 3. Torsion springs 5 are sleeved on the two fixed shafts 3. One ends of the two torsion springs 5 close to each other are fixedly connected to the corresponding connecting blocks 4 respectively, and the other ends of the two torsion springs 5 away from each other are fixedly connected to the corresponding fixing blocks 2 respectively. Limiting pieces are fixedly installed at one ends of the two fixing shafts 3 close to each other for preventing the connecting blocks 4 from slipping off the fixed shafts 3. The same protective cover 6 is fixedly installed at the bottom of the two connecting blocks 4. The protective cover 6 is used to isolate and protect the keys and display screen on the panel of the air conditioner fresh air controller body 1 to prevent being accidentally touched by children. The protective cover 6 includes a frame body 61 and a cover plate 62. The cover plate 62 is fixedly installed on the frame body 61. A notch 611 is provided at the bottom of the frame body 61. Sockets are opened on the inner walls of both sides of the notch 611. A protective box 7 located in the notch 611 is fixedly installed on the panel of the air conditioner fresh air controller body 1. The protective box 7 includes two side plates 71 and a box body 72. The box body 72 is fixedly installed between the two side plates 71. In order to limit the protective cover 6 and prevent the protective cover 6 from being easily opened, insertion blocks 8 penetrate through and are slidably installed on the two side plates 71 respectively. One ends of the two insertion blocks 8 away from each other extend into the corresponding sockets respectively. End plates 9 are fixedly installed at one ends of the two insertion blocks 8 close to each other. Return springs 10 are sleeved on the two insertion blocks 8 respectively. One ends of the two return springs 10 close to each other are fixedly connected to the corresponding end plates 9 respectively, and the other ends of the two return springs 10 away from each other are fixedly connected to the corresponding side plates 71 respectively. L-shaped hand blocks 11 are fixedly installed on the two end plates 9 respectively. The two L-shaped hand blocks 11 are both slidably connected to the box body 72. Specifically, two limiting sliding openings are opened at the bottom of the box body 72. The two L-shaped hand blocks 11 both penetrate through the corresponding limiting sliding openings and are slidably connected to the inner walls of the corresponding limiting sliding openings.

[0028] In the process of closing the protective cover 6 downward, in order to enable the two plug blocks 8 to be automatically inserted into the corresponding sockets, in this embodiment, the ends of the two plug blocks 8 that are away from each other are provided with an inclined sliding surface 81. In the process of closing the protective cover 6, the inclined sliding surface 81 of the two plug blocks 8 will be abutted. Under the action of the horizontal component of the abutting force, the two plug blocks 8 will automatically move toward each other, and the two return springs 10 will be stretched first. When the protective cover 6 is closed in place, the two plug blocks 8 will be axially aligned with the corresponding sockets. Under the pull of the two return springs 10, the two plug blocks 8 will move back to back, and the end with the inclined sliding surface 81 will be automatically inserted into the corresponding socket.

[0029] In this embodiment, in order to further increase the operating steps for opening the protective cover 6 and increase the difficulty for children to open the protective cover 6, a limiting plate 12 is slidably installed on the cover plate 62. The limiting plate 12 is made of stainless steel. The bottom of the limiting plate 12 extends between the two L-shaped hand blocks 11. A magnet block 13 is fixedly installed on the cover plate 62 and is located above the L-shaped hand block 11.

[0030] In this embodiment, in order to allow the limiting plate 12 to enter between the two L-shaped hand blocks 11 more smoothly, the two corners of the bottom of the limiting plate 12 are both rounded.

[0031] In this embodiment, in order to facilitate the user to operate the limiting plate 12 , a toggle bar is fixedly mounted on the limiting plate 12 .

[0032] The working principle of the air conditioning fresh air controller with a protective mechanism provided by this utility model is as follows:

[0033] In the initial state, the protective cover 6 is in the closed state. When the air-conditioning fresh air controller body 1 needs to be operated, the limiting plate 12 is first pushed upward until the limiting plate 12 contacts the magnet block 13. The magnet block 13 can adsorb the limiting plate 12 and prevent it from falling. Then, the index finger and thumb are used to respectively buckle the two L-shaped hand blocks 11 so that the two move toward each other. The two L-shaped hand blocks 11 respectively drive the two plug blocks 8 to move accordingly, so that the two plug blocks 8 exit the corresponding sockets. In this way, the frame 61 loses its restriction. Under the torsion of the two torsion springs 5, the protective cover 6 will automatically rotate upward, that is, the opening of the protective cover 6 is realized. Then the relevant user can operate the buttons on the panel of the air-conditioning fresh air controller body 1;

[0034] When there are children at home, in order to prevent children from accidentally operating the buttons on the air-conditioning fresh air controller body 1 due to curiosity, after the parents have completed the settings, they can press the protective cover 6 downward with a little force. During the downward rotation of the protective cover 6 (i.e. the closing process), it will contact the inclined sliding surfaces 81 of the two plug blocks 8. Under the action of the horizontal component of the resistance force, the two plug blocks 8 will automatically move toward each other, and the two return springs 10 will be stretched first. When the protective cover 6 is closed in place, the two plug blocks 8 will be axially aligned with the corresponding sockets. Under the pull of the two return springs 10, the two plug blocks 8 will move back to back, and the end with the inclined sliding surface 81 will automatically insert into the corresponding socket, thereby preventing The protective cover 6 is reset upward, so that the buttons and display screen on the panel of the air-conditioning fresh air controller body 1 are completely covered by the protective cover 6 to prevent them from being accidentally touched by children. Then, the limiting plate 12 is pushed downward with a little force to separate it from the magnet block 13. The limiting plate 12 will eventually enter between the two L-shaped hand blocks 11. Due to the blocking effect of the limiting plate 12, the two L-shaped hand blocks 11 cannot be pressed to move toward each other. The limiting plate 12 needs to be pushed upward first before the two L-shaped hand blocks 11 can be operated. Therefore, it is relatively difficult for children to open the protective cover 6. For adults, it is relatively simple to first push the limiting plate 12 upward and then press the two L-shaped hand blocks 11 to move toward each other.

[0035] Compared with the related art, the air conditioner fresh air controller with a protective mechanism provided by the present invention has the following beneficial effects:

[0036] The utility model provides an air-conditioning fresh air controller with a protective mechanism. Through the arrangement of components such as the protective cover 6, the fixed block 2, the fixed shaft 3, the connecting block 4, the torsion spring 5, the protective box 7, the plug block 8, the end plate 9, the return spring 10, and the L-shaped hand block 11, the protective cover 6 can be restricted after being closed, and the panel of the air-conditioning fresh air controller body 1 can be reliably isolated and protected to prevent children from accidentally touching the screen and buttons on the panel. At the same time, through the arrangement of the limiting plate 12, the two L-shaped hand blocks 11 can be restricted after the protective cover 6 is closed, which increases the operating steps for opening the protective cover 6, so that children cannot easily open the protective cover 6, while the operation is relatively simple for adults, thereby increasing the reliability of the panel protection of the air-conditioning fresh air controller body 1.
