[0043] The specific embodiments shown below are intended to be descriptions of various configurations of the subject technology of the present invention, and are not intended to represent the only configuration in which the subject technology of the present invention can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and obvious to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be practiced without these specific details.

[0044] Reference Figures 1 to 7 As shown, the wireless room temperature collector comprises a shell 1, wherein the shell 1 is provided with a mounting cavity 11;

[0045] The shell 1 is further provided with a cover 2, and the cover 2 closes the installation cavity 11; the shell 1 can be made of plastic material, and the shell 1 and the cover 2 can also be made of other insulating materials.

[0046] The shell 1 is provided with a plug 12 electrically connected to a power source; the plug 12 can be matched with a socket, and the socket is provided with a jack matched with the plug 12, and the socket is usually connected to the mains.

[0047] A heat insulation board 13 is arranged in the installation cavity 11, and the heat insulation board 13 divides the installation cavity 11 into a power cavity 14, a circuit cavity 15 located below the power cavity 14, an expansion cavity 16 located below the circuit cavity 15, and a collection cavity 17 located below the expansion cavity 16. The heat insulation board 13 can be made of wood material, or the heat insulation board 13 can also be made of other materials with heat insulation capabilities.

[0048] The power cavity 14 is provided with an adapter 141, which is electrically connected to the plug 12. The power cavity 14 is also provided with a battery 142, which is electrically connected to the adapter 141. The circuit cavity 15 is provided with a circuit board 151, which is electrically connected to the adapter 141. The circuit board 151 can be powered by the adapter 141, or by the battery 142. When the socket can provide power, the power is adjusted to reasonable parameters by the adapter 141 and directly supplied to the circuit board 151. At the same time, the power output by the adapter 141 can charge the battery 142. When the socket cannot provide power, since the adapter 141 cannot output power, the battery 142 can supply power to the circuit board 151. A control chip can be integrated on the circuit board 151 to control the working status of the adapter 141 and the battery 142.

[0049] An expander 161 is disposed in the expansion cavity 16 . The expander 161 includes a high-voltage socket 162 and a low-voltage socket 163 . The high-voltage socket 162 is electrically connected to the plug 12 , and the low-voltage socket 163 is electrically connected to the adapter 141 .

[0050] The power output by the strong current interface has the same parameters as the power output by the socket, so the strong current interface can be connected in parallel with the adapter 141 to the plug 12. The strong current interface is used to increase the functions of the wireless room temperature collector so that the socket can output power through the strong current socket 162. The weak current interface can be a USB interface, and the weak current interface is provided with power by the adapter 141 or the battery 142. The weak current interface is electrically connected to the adapter 141 and the battery 142 through the circuit board 151.

[0051] The collection chamber 17 is provided with a temperature collector 171, and the temperature collector 171 is electrically connected to the adapter 141 through the circuit board 151;

[0052] The temperature collector 171 may be a temperature sensor in the prior art and may be powered by the adapter 141 or the battery 142 .

[0053] A heat sink 164 is disposed in the expansion cavity 16 .

[0054] An alarm may also be provided on the housing 1, and the alarm is used to send an alarm signal when the temperature collected by the temperature collector 171 is too high or too low. The alarm may be a sound alarm, a light alarm, or an audible and visual alarm. The alarm is controlled by the circuit board 151, and the alarm may be powered by the adapter 141 or the battery 142.

[0055] Exemplarily, the alarm is a display, which is controlled by the circuit board 151 and powered by the adapter 141 or the battery 142. The display will emit a certain amount of heat during operation, so the display should be arranged at a position away from the temperature collector 171, for example, it can be arranged at a position where the cover 2 faces the power cavity 14.

[0056] Configuration in this article refers to installing one component on another component. Configuration can be achieved by fixing one component on another component in a detachable or non-detachable manner. The detachable connection can be achieved by screw connection, etc., and the non-detachable connection can be achieved by bonding, etc.

[0057] The heat sink 164 is a common heat dissipation structure in the prior art. The main function of the heat sink 164 is to dissipate the temperature in the circuit cavity 15 or the power cavity 14 to prevent the heat in the circuit cavity 15 and / or the power cavity 14 from entering the collection cavity 17, so that the temperature collector in the collection cavity 17 is not easily disturbed, and the temperature collector 171 can work in a better environment and is not easily damaged.

[0058] After absorbing heat, the heat sink 164 usually needs to dissipate the absorbed heat into the air to achieve natural heat dissipation. Of course, the heat sink 164 can also use a semiconductor cooling sheet to achieve the heat dissipation function. Taking natural heat dissipation as an example, the use cost of the wireless room temperature collector can be reduced by using natural heat dissipation. To this end, in some embodiments, the high-voltage socket 162 is connected to the expansion cavity 16.

[0059] The low-voltage socket 163 is communicated with the expansion cavity 16 .

[0060] The heat absorbed by the heat sink 164 can be dissipated into the air through the weak current socket 163 and / or the strong current socket 162, so that the heat sink 164 has better heat dissipation performance. The cover 2 is equipped with a hole 21 that matches the weak current socket 163 and the strong current socket 162.

[0061] Reference Figures 3 to 7As shown, in some embodiments, the heat insulation board 13 is provided between the power cavity 14 and the circuit cavity 15, between the circuit cavity 15 and the extension cavity 16, and between the extension cavity 16 and the collection cavity 17, and each of the heat insulation boards 13 is provided with a wire groove 131 passing through the heat insulation board 13. The wire groove 131 is used to lay wires, and the electrical connection between the electronic components of the wireless room temperature collector can be achieved by wires.

[0062] The upper end of the heat sink 164 contacts the heat insulation plate 13 between the extension cavity 16 and the circuit cavity 15, and the lower end of the heat sink 164 does not contact the heat insulation plate 13 between the extension cavity 16 and the collection cavity 17, thereby preventing heat from entering the collection cavity 17 through the heat sink 164 and the heat insulation plate 13.

[0063] There are a plurality of heat sinks 164, and a wire passing space is formed between two adjacent heat sinks 164 for the wires to pass through. The wire passing space is formed between the heat sinks 164, which can reduce the volume of the shell 1. Heat sinks 164 are provided on both sides of the expander 161, and at least two heat sinks 164 can be provided on each side of the expander 161.

[0064] In some embodiments, the wire groove 131 is in a long strip shape, and the wire groove 131 is arranged along the depth direction of the installation cavity 11 .

[0065] Reference Figures 3 to 7 As shown, in some embodiments, the adapter 141 and the battery 142 will generate a large amount of heat energy during operation. Therefore, it is necessary to further improve the heat dissipation capacity of the power cavity 14. To this end, the upper end of the shell 1 is provided with heat dissipation holes 18, and the heat dissipation holes 18 are communicated with the power cavity 14. The upper end of the shell 1 is also provided with a plate 19 covering all the heat dissipation holes 18, and the plate 19 is fixed to the upper end of the shell 1 through the thermal extension column 182.

[0066] A groove body 181 is provided at the upper end of the shell 1, and the groove body 181 cooperates with the plate 19. The depth of the groove body 181 is not less than the thickness of the plate 19. The groove body 181 is located outside the installation cavity 11, and the groove body 181 is connected to the power cavity 14 through the heat dissipation hole 18. The lower end of the thermal extension column 182 is bonded to the bottom wall of the groove body 181, and the upper end of the thermal extension column 182 is bonded to the plate 19.

[0067] The plate 19 is mainly used to cover and close the heat dissipation hole 18. When the adapter 141 and the battery 142 are not working, the heat dissipation hole 18 can be closed to prevent dust from entering the power cavity 14. When the adapter 141 and the battery 142 are not working, the temperature in the power cavity 14 is not high. At this time, the length of the thermal extension column 182 is shortened, and the plate 19 enters the slot 181. When the adapter 141 and / or the battery 142 are working, the temperature of the power cavity 14 rises, the length of the thermal extension column 182 increases, the plate 19 leaves the slot 181, and the heat dissipation hole 18 can perform normal heat dissipation.

[0068] The heat-extending column 182 is used to control the plate 19 to enter or leave the slot 181, which further simplifies the structure of the shell 1.

[0069] In some embodiments, the weak current socket 163 is located within the circumscribed circle of the strong current socket 162. The weak current socket 163 and the strong current socket 162 are respectively matched with different connectors, so the weak current socket 163 and the strong current socket 162 cannot be used at the same time. When there is a connector in the strong current socket 162, the weak current socket 163 is covered 2, and when there is a connector in the weak current socket 163, a part of the strong current interface is covered 2, which improves the safety characteristics of the wireless room temperature collector.

It can be understood that the above introduction is only some implementation plans of the subject technical solution of the utility model, and some details can be omitted during the specific implementation.
