CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202321555806.8, filed on Jun. 16, 2023, which is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the technical field of cameras, and particularly relates to a hidden bidirectional rotary camera with a temperature and humidity sensing function.

BACKGROUND

Existing cameras are basically characterized in that a ball-head part only realizes an up-down angle rotation function under the control of a motor, a base part and a ball-head realize a left-right rotation function together, and the ball-head part needs to be wrapped with a shell, so that a motor shaft may be fixed to the shell to realize the up-down rotation function of the ball-head. Although such solution realizes the up-down and left-right rotation function of the camera, but also has the following defects: 1, the appearance is limited, namely, the ball-head part needs to be wrapped with the shell, and the ball-head part needs to rotate at an angle up and down by taking the shell as a rotary supporting point, so the appearance cannot be diversified; 2, a necessary component of the shell is added, so the product cost is increased; and 3, vertical and horizontal rotation motion of only the ball-head part cannot be realized.

According to this solution, the overall shape of the streamline of the base in design is more similar to that of baby products. The appearance design of a traditional ball-head machine structure is abandoned, and horizontal and vertical rotation angles are realized on one ball-head. The traditional ball-head machine can only realize vertical rotation of the ball-head, and horizontal rotation can be realized only by combining the base and the ball-head.

Moreover, a temperature and humidity sensing module of the existing camera product needs to be separated from the camera, so as to better contact and sense the temperature and humidity of the external air; and although the temperature and humidity of the external air can be sensed through such solution, but it has the following defects: 1, the appearance is limited, an independent temperature and humidity sensing module needs to be made, which is not matched with the shape of the camera product; and 2, a shell needs to be additionally arranged to wrap the temperature and humidity sensor when the independent temperature and humidity sensing module is made, which causes the increase of the product cost.

The application number CN201710566376.2 discloses a camera; a horizontal rotating mechanism is arranged in a base of the camera; a main body is connected to a rotating shaft of the horizontal rotating mechanism, so that the main body may rotate in the horizontal direction; a vertical rotating mechanism and a camera assembly are arranged in a ball-head, and the ball-head is rotationally connected to the body; and the ball-head is fixed in a ball-head cavity through a rotating shaft of the vertical rotating mechanism, so that the ball-head vertically rotates in the ball-head cavity. According to the above patent, only vertical rotation of the ball-head can be realized, and horizontal rotation can be realized only by combining the base and the ball-head, which causes the limitation on the appearance and the increase of the product cost.

The utility model patent with the application number CN201621456808.1 discloses a household multi-functional network monitoring camera based on safety; and a temperature and humidity sensor of the camera is arranged on the side surface of a base and is in direct contact with external air, so that the structural volume of the base is increased, the shape of the base is limited, and the manufacturing cost of the camera is increased.
