[0002] The fresh air controller is a device that can control the fresh air system. It can directly adjust the indoor air conditions by adjusting the control panel to keep the indoor air clean and easy to operate. The installation process of the fresh air controller is to first drill a hole in the wall, assemble the shell on the wall and fix it with mortar, and finally install the control panel on the shell with bolts. When the control panel is installed on the shell, it is impossible to observe with the naked eye whether the bolts are aligned with the connecting holes, and the position needs to be constantly adjusted. The installation process is more troublesome and the construction efficiency is low. Therefore, it is necessary to propose a fresh air controller that is easy to install. Utility Model Content

DETAILED DESCRIPTION

[0023] Below we further illustrate the conveniently installed fresh air controller described in the present invention through embodiments and in conjunction with the accompanying drawings.

[0024] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention 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.

[0025] In the present invention, unless otherwise clearly specified or limited, the terms "connected", "fixed" and the like should be understood in a broad sense.

[0026] For example, "fixed" can be fixed connection, detachable connection, or integrated; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium, 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.

[0027] See also Figures 1 to 7As shown, the utility model proposes a fresh air controller that is easy to install, including a shell 1 and a controller 2 installed on the shell 1, which is characterized in that it includes a quick-install structure arranged to connect and fix the controller 2 to the shell 1 and a reinforcing structure installed on the shell 1 to strengthen the connection strength between the shell 1 and the wall. The quick-install structure includes a base 21 arranged on the controller 2, a shaft rod 22 movably installed on the base 21, and a positioning pin 23 movably installed on the base 21 and contact-connected with the shaft rod 22. The controller 2 is provided with a through hole 24 that facilitates the movement of the shaft rod 22, an eccentric wheel 25 that matches the positioning pin 23 is installed on the shaft rod 22, a sealing head 30 is also installed on the through hole 24, the eccentric wheel 25 is provided with a fitting surface 26 that matches the positioning pin 23, the positioning pin 23 is provided with a boss 27, the positioning pin 23 is also provided with a spring 28, and the shell 1 is provided with a spring 29 that matches the positioning pin 23. The housing 1 is provided with a positioning hole 11, the controller 2 is provided with a positioning column 12 which matches the positioning hole 11, the housing 1 is also provided with a winding column 13, the winding column 13 is provided with an anti-slipping plate 14, and the housing 1 is also provided with a threading hole 15; through the setting of the quick-install structure, the trouble of traditionally fixing the controller 2 with bolts is changed, the positioning column 12 and the positioning hole 11 are used to position the controller 2, and then the positioning pin 23 is inserted into the locking hole 29 by rotating the shaft 22, so as to realize quick installation and improve the construction efficiency; through the setting of the fitting surface 26, the contact area between the eccentric wheel 25 and the end face of the positioning pin 23 is increased when the positioning pin 23 is locked, thereby ensuring that the positioning pin 23 cannot be detached from the lock 29 hole, thereby improving the installation stability of the controller 2; through the setting of the anti-slipping plate 14, the cable is limited on the winding column 13 to prevent it from spreading, and the cable is managed in order.

[0028] The reinforcement structure includes a slide seat 31 arranged on the shell 1, and a limit platform 32 slidably installed on the slide seat 31 and can pass through the shell 1. The slide seat 31 is provided with a screw rod 33 movably connected to the limit platform 32 through a threaded connection, and the limit platform 32 is provided with barbs 34. Through the setting of the reinforcement structure, by rotating the screw rod 33, the screw rod 33 pushes the limit platform 32 along the slide seat 31 to extend out of the shell 1 to both sides, so that the barbs 34 are inserted into the wall, thereby enhancing the connection strength between the shell 1 and the wall, preventing the shell 1 from being pulled out of the wall, and improving the stability of the installation of the shell 1.

[0029] When the utility model is used, the shell 1 is placed in a wall with a hole, the cable is passed through the shell 1 from the threading hole 15, the cable is wound on the winding post 13 for multiple turns and then connected to the controller 2, the positioning post 12 is aligned with the positioning hole 11, and the controller 2 is pushed toward the shell 1 so that the positioning post 12 is inserted into the positioning hole 11 until the controller 2 is tightly attached to the shell; at this time, the shaft rod 22 is rotated left or right by a tool, and the shaft rod 22 drives the eccentric wheel 25, and the eccentric wheel 25 pushes the positioning pin 23 to move outward and compresses the spring 28 during the rotation, until the eccentric wheel 25 rotates 180 degrees so that one end of the positioning pin 23 is tightly attached to the fitting surface 26, and at this time the positioning pin 23 extends out of the base 21 and is inserted into the lock hole 29, so that the controller 2 is quickly assembled on the shell 1, and finally the sealing head 30 is installed on the through hole 24.

[0030] When disassembling the controller 2, first take out the sealing head 30 and rotate it 180 degrees to the left or right. The fitting surface 26 will disengage from the positioning pin 23 during the rotation. At this time, the positioning pin 23 will retract into the base 21 under the rebound force of the spring 28, so that the positioning pin 23 will leave the lock hole 29, so that the controller 2 can be disengaged from the shell 1, which is convenient for subsequent maintenance.

[0031] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
