Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.
Example 1
The present embodiment relates to a freely rotatable intelligent gas sensor, as shown in fig. 1, including: shell 1, gas sensor body 7, mark gas cover 2 and air cock 3.
Wherein, the gas sensor body 7 is assembled in the housing 1 at one end of the housing 1. The side of the air faucet cover 2 is symmetrically provided with two mounting holes for installing the air faucet 3, and one end of the air faucet 3 penetrates through the mounting holes to be assembled on the air faucet cover 2, so that the air is collected in the horizontal direction. In other embodiments, a mounting hole is provided at the bottom of the target gas cover 2, and one end of the gas nozzle 3 is fitted to the target gas cover 2 through the mounting hole to facilitate gas collection in the longitudinal direction. The gas marking cover 2 is connected with the shell 1 in a threaded manner. Specifically, be provided with first screw thread 4 on the mark gas cover 2, 1 one end of shell is provided with the second screw thread 5 with 4 adaptations of first screw thread, marks gas cover 2 and realizes being connected with shell 1 through first screw thread 4 and second screw thread 5.
In order to adjust the collecting direction of the standard gas cover 2 and the gas nozzle 3, the requirement on the collecting direction of the gas is met. The first thread 4 is an internal thread and the second thread 5 is an external thread. Be close to first screw thread 4 on the mark gas cover 2, and keep away from its bead department and be provided with 5 spacing grooves of second screw thread, 5 spacing grooves of second screw thread are used for supplying 5 holding of second screw thread so that mark gas cover 2 can carry out 360 degrees rotations for shell 1 to it is adjustable to realize the collection direction of mark gas cover 2 and air cock 3.
In order to avoid the air leakage phenomenon when the standard gas cover 2 and the air nozzle 3 rotate, a first accommodating groove b is arranged on the shell 1 and close to the edge of the standard gas cover 2, and a sealing piece 6 is assembled in the first accommodating groove b.
