At this time, the connection seat 6 and the high-strength glass tube 9 can be pulled out horizontally, which is convenient for the later inspection and maintenance of the functional assembly seat 2 and the high-strength glass tube 9.

[0040] In this embodiment: according to the use of the wireless remote control shell 1, it can be determined whether to install the functional assembly seat 2, and whether to install one or two functional assembly seats 2. When the functional assembly seat 2 and the wireless remote control shell 1 are installed, the two positioning blocks 4 of the functional assembly seat 2 are first inserted into the two positioning holes 3 of the wireless remote control shell 1 for preliminary positioning, and then the functional assembly seat 2 and the wireless remote control shell 1 are fixedly connected by screws. When the wireless remote control shell 1 normally remotely controls the mechanical equipment, as the operator moves away from the remote control receiver of the mechanical equipment, the positioning sensing module 27 senses the relative distance position in real time. When the distance is within the safe range, the warning light group 13 displays a green light. At a longer distance but without affecting safety, the warning light group 13 displays a yellow light.

[0041] Embodiment 2: On the basis of embodiment 1, when the wireless remote control housing 1 is used in a cold environment, the wireless remote control housing 1 can be subjected to a constant temperature treatment, a power chamber 21 is provided on one side of the functional assembly seat 2 close to the circulating return air outlet 10, a driving motor 22 is horizontally installed in the power chamber 21, a fan blade 23 is provided on one side of the output shaft of the driving motor 22, an input air hole 24 is provided on one side of the power chamber 21 connected to the assembly slot 7, an air inlet pipe 25 is integrally provided on one side of the high-strength glass tube 9 located at the circulating return air outlet 10, after the circulating return air outlet 10 is plugged into the docking slot of the functional assembly seat 2, the air inlet pipe 25 is connected and docked with the input air hole 24, when the driving motor 22 drives the fan blade 23 to rotate, the fan blade 23 blows the air in the high-strength glass tube 9 through the air inlet pipe 25, at this time, the air in the high-strength glass tube 9 enters and exits the high-strength glass tube 9 from the circulating return air outlet 10 and the circulating air outlet 11 respectively, at this time, the air circulation is the self-circulation of the air in the wireless remote control housing 1;

[0042] The warning light group 13 is arranged on one side of the high-strength glass tube 9 close to the air inlet pipe 25. The air inlet pipe 25 and the middle section of the high-strength glass tube 9 are on the same virtual axis. A spiral heating wire 26 is horizontally arranged on one side of the middle section of the high-strength glass tube 9 away from the air inlet pipe 25. The spiral heating wire 26 does not contact the inner wall of the high-strength glass tube 9, and the two sides of the spiral heating wire 26 respectively penetrate the high-strength glass tube 9 and one side of the power receiving seat 6 and are electrically connected to the control circuit board 12. When the wireless remote control housing 1 is used outdoors in a cold area, the spiral heating wire 26 is energized to generate heat that is not hot to the touch. At this time, the wind blown into the high-strength glass tube 9 by the fan blades 23 is heated after contacting the spiral heating wire 26. At this time, the hot wind enters the wireless remote control housing 1 The air in the high-strength glass tube 9 and the wireless remote control housing 1 circulates in the air, which helps to increase the temperature in the wireless remote control housing 1 in cold weather. When the hot air passes through the high-strength glass tube 9, the operator holding the wireless remote control housing 1 needs to contact the high-strength glass tube 9, which can warm the operator's hands and prevent the operator from freezing his fingers during long-term outdoor operations, which affects the remote control operation. Similarly, in hot summer, when the remote control is performed outdoors, the spiral heating wire 26 is not started, and the wind blown into the high-strength glass tube 9 by the fan blades 23 can dissipate heat to a certain extent for the electrical components in the wireless remote control housing 1.

[0043] In addition, a rechargeable battery can be provided in the positioning sensing module 27 to provide power to the spiral heating wire 26 and the warning light group 13. When the battery in the wireless remote control housing 1 is out of power, an adapter structure can also be designed to provide a backup power supply for the wireless remote control housing 1.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
