[0033] like Figures 2 to 5 As shown, the housing 1 includes a first shell 11 and a second shell 12 , and the first shell 11 and the second shell 12 cover each other to form a receiving cavity 13 .

[0034] Specifically, Figure 6 and Figure 7 As shown, the second shell 12 is provided with a connection block 121 and a connection column 122.

[0035] like Figure 5 , Figure 8 and Fig. 9 As shown, the first shell 11 is provided with a groove 110, a block 111, a support column 112, a limit block 113 and a magnetic plate 114.

The other end of the support column 112 is provided with an annular step 1120. The support column 112 is used to pass through the main circuit board 2 and then be plugged into the connection hole 1220 of the connection column 122, thereby strengthening the fixed connection between the first shell 11 and the second shell 12. In addition, the annular step 1120 abuts against the main circuit board 2 to support the main circuit board 2. The limit block 113 is arranged around the groove 110, and the limit block 113 is used to limit the power supply module 7 and the detection module 3. The magnetic plate 114 is located in the groove 110 , and the magnetic plate 114 is used to be magnetically fixed to an external metal part or magnetic part, so that the housing 1 is fixed to the metal part or magnetic part.

[0036] In some embodiments, a clamp 115 is further provided on the outer side of the bottom surface of the first shell 11, and the clamp 115 is used to clamp the shell 1 to an external object, etc. The clamp 115 can realize convenient fixing and removal of the shell 1 from the outside. The clamp 115 can be detachably connected to the first shell 11.

[0037] In some embodiments, the connection between the bottom surface and the side surface of the first shell 11 is arranged in an arc-shaped chamfer. Compared with a right-angle connection, the arc-shaped chamfer is more beautiful.

[0038] In some embodiments, the first shell 11 or the second shell 12 of the housing 1 is further provided with a lanyard through hole 116, and the lanyard through hole 116 is used for a lanyard to pass through so as to carry the housing 1 or hang it fixedly.

[0039] like Figure 4 , Figure 5 , Fig.10 and Fig.11As shown, the main circuit board 2 is arranged in the accommodating cavity 13, and the main circuit board 2 has a first surface 21 and a second surface 22. The first surface 21 and the second surface 22 are arranged opposite to each other along the thickness direction of the main circuit board 2, the first surface 21 faces the bottom surface of the first shell 11, and the second surface 22 faces the bottom surface of the second shell 12. The main circuit board 2 is passed through by the support column 112, the first surface 21 is supported by the annular step 1120 of the support column 112, and the second surface 22 abuts against the end surface of the other end of the connecting column 122, and the annular step 1120 and the connecting column 122 clamp and fix the main circuit board 2.

[0040] like Figure 4 , Fig.11 and Fig.12 As shown, the detection module 3 is disposed on the first surface 21 of the main circuit board 2 and is disposed close to one side of the first surface 21. The detection module 3 includes a detection element 31 and a mounting circuit board 32, the mounting circuit board 32 is disposed on the first surface 21 of the main circuit board 2, and the detection element 31 is disposed on the mounting circuit board 32 and is disposed upright relative to the first surface 21. In some embodiments, the mounting circuit board 32 is plugged into the main circuit board 2.

[0041] Typically, the mounting circuit board 32 is vertically disposed on the first surface 21, and the detection element 31 is disposed on the mounting circuit board 32 in a flat state, so that the detection element 31 is vertically disposed relative to the first surface 21. In some embodiments, the thickness direction of the detection element 31 is parallel to the first surface 21, and the thickness direction of the mounting circuit board 32 is also parallel to the first surface 21. In some embodiments, the detection element 31 is disposed on the mounting circuit board 32 using surface mounting technology.

[0042] The shielding cover 9 is arranged on the first surface 21, and covers the detection module 3. The shielding cover 9 plays an electromagnetic shielding role on the detection module 3 to prevent other electronic components from generating electromagnetic interference to the detection module 3, wherein the shielding cover 9 is made of metal material. Of course, the shielding cover 9 can also be made of other materials with electromagnetic shielding function.

[0043] In some embodiments, Fig.13 As shown, the detection element 31 includes a radiation absorption layer 311 and an electronic device layer 312, and the radiation absorption layer 311 and the electronic device layer 312 are both made of semiconductor materials. The radiation absorption layer 311 and the electronic device layer 312 are stacked. The radiation absorption layer 311 is arranged vertically relative to the first surface 21. In some embodiments, the thickness direction of the radiation absorption layer 311 and the thickness direction of the electronic device layer 312 are both parallel to the thickness direction of the mounting circuit board 32. The radiation absorption layer 311 is used to absorb radiation to generate an electrical signal, and the electronic device layer 312 is used to process the electrical signal generated by the radiation absorption layer 311 and generate a radiation signal.

[0044] It should be noted that when a user uses the radiation detection device 1000 to detect radiation, the first surface 21 of the main circuit board 2 is usually facing the radiation source. If the detection element 31 is directly arranged on the main circuit board 2 in a flat state, the radiation is usually incident from the surface of the radiation absorption layer 311, that is, it is roughly incident along the thickness direction of the radiation absorption layer 311, resulting in a shorter path for the radiation to travel in the radiation absorption layer 311. Since radiation usually has strong penetrability, the radiation absorption layer 311 absorbs radiation for a shorter time at this time, resulting in the radiation absorption layer 311 responding to the radiation. The ability is weak, resulting in low sensitivity of the radiation detection device 1000; in comparison, when the radiation absorbing layer 311 is arranged upright relative to the first surface 21 of the main circuit board 2, the radiation is usually incident from the side of the radiation absorbing layer 311, that is, roughly along the length direction or width direction of the radiation absorbing layer 311, which greatly prolongs the path of the radiation traveling in the radiation absorbing layer 311, thereby prolonging the time for the radiation absorbing layer 311 to absorb radiation, improving the response ability of the radiation absorbing layer 311 to radiation, and thus improving the sensitivity of the radiation detection device 1000.

[0045] In addition, since the mounting circuit board 32 is vertically arranged on the first surface 21, compared with directly arranging the detection element 31 in a flat state on the main circuit board 2, the area occupied by the detection module 3 on the first surface 21 of the main circuit board 2 is smaller, so the size of the main circuit board 2 can be reduced, which is conducive to the miniaturization of the radiation detection device 1000 and improves the portability.

[0046] Please continue reading Fig.11 The wireless communication module 5 and the power supply module 7 are both disposed on the first surface 21 of the main circuit board 2. In some embodiments, the wireless communication module 5 is a Bluetooth module, and the power supply module 7 is a battery.

[0047] The wireless communication module 5 is plugged into the main circuit board 2 and is disposed close to the other side of the first surface 21 away from the detection module 3 .

[0048] The power supply module 7 is arranged in the central area of ​​the first surface 21. In the direction parallel to the first surface 21, the power supply module 7 and the detection module 3 are arranged side by side and spaced apart. The power supply module 7 is located between the wireless communication module 5 and the detection module 3. The thickness direction of the power supply module 7 is perpendicular to the first surface 21. When the power supply module 7 is installed in the receiving cavity 13, the power supply module 7 partially extends into the space surrounded by the limiting column 113, and the limiting column 113 plays a role in limiting the power supply module 7.

[0049] It should be noted that the detection module 3 and the power supply module 7 are arranged side by side and spaced apart on the same surface of the main circuit board 2, and the power supply module usually has a considerable thickness. Therefore, compared with directly arranging the detection element 31 in a flat state on the main circuit board 2, the space between the first shell 11 and the first surface 21 for accommodating the detection module 3 can be reduced, and the internal structure of the radiation detection device 1000 is more compact, and the utilization rate of the internal space is higher. The wireless communication module 5 and the detection module 3 are arranged at the two side edges of the first surface 21 relative to each other, reducing the signal interference to each other, and the wireless communication module 5 and the detection module 3 are both arranged at the corners of the main circuit, with fewer electronic devices around, reducing the signal interference of electronic devices to wireless communication and radiation detection.

[0050] In some embodiments, the radiation detection device 1000 further includes a key module 10, which includes a first key 101, a second key 102, a third key 103 and a key cover 104. One end of each key is disposed on the main circuit board 2, and the other end of each key is nested in the key cover 104. The first key 101 is used for power on / off and returning to the main interface, the second key 102 is used for setting functions, and the third key 103 is used for switching display interfaces. The surface of the key cover 104 does not protrude from the side surface of the housing 1, making the appearance of the housing 1 more beautiful. The key cover 104 is provided with an arc frame, which matches the shape of the inner wall of the second housing 12. The setting of the arc frame increases the force application area, so that when the user uses the key function, the key will not be over-pressed, thereby extending the service life of the key.

[0051] It is understandable that the number and functions of the buttons are not limited to the above, and can be specifically set according to actual applications.

[0052] Please refer to Fig.10 The processor 4, the display module 6 and the speaker 8 are all arranged on the second surface 22 of the main circuit board 2, and the display module 6 and the speaker 8 are both connected to the processor 4 in communication. The display module 6 is arranged corresponding to the translucent plate 123 of the second shell 12. When the detection element 31 detects radiation and generates a radiation signal, the processor 4 determines the radiation dose according to the radiation signal, and then displays the radiation dose on the display module 6. The user can visually observe the radiation dose through the translucent plate 123. In addition, when the radiation dose exceeds the preset threshold, the processor 4 controls the speaker 8 to sound an alarm to remind the user that the current radiation exceeds the standard.

[0053] In some embodiments, Fig.11 and Fig.12As shown, the main circuit board 2 is also provided with a connector 23, which is arranged at one end of the first surface 21. The processor 4 and the power supply module 7 are both electrically connected to the connector 23. The connector 23 is used to connect to an external power supply to charge the power supply module 7 or to realize a wired communication connection between the radiation detection device 1000 and an external device.

[0054] In the embodiment of the utility model, the radiation detection device 1000 includes a housing 1, a main circuit board 2, a detection module 3, a processor 4, a wireless communication module 5, a display module 6, a power supply module 7 and a speaker 8. The housing 1 is provided with a receiving cavity 13, the main circuit board 2 is arranged in the receiving cavity 13, and the detection module 3, the processor 4, the wireless communication module 5, the display module 6, the power supply module 7 and the speaker 8 are all arranged on the main circuit board 2. The main circuit board 2 includes a first surface 21 and a second surface 22 arranged opposite to each other. The detection module 3 includes a detection element 31 and a mounting circuit board 32. The mounting circuit board 32 is vertically arranged on the first surface 21. The detection element 31 is arranged on the mounting circuit board 32 in a flat state, so that the detection element 31 is arranged vertically relative to the first surface 21. Compared with the detection element 31 being directly arranged on the main circuit board 2 in a flat state, the path of radiation traveling in the detection element 31 is greatly extended, thereby extending the time for the detection element 31 to absorb radiation, and improving the response ability of the detection element 31 to radiation, thereby improving the sensitivity of the radiation detection device 1000. Moreover, the vertically arranged mounting circuit board 32 makes the area occupied by the detection module 3 on the first surface 21 of the main circuit board 2 smaller, so that the size of the main circuit board 2 can be reduced, which is conducive to the miniaturization of the radiation detection device 1000 and improves the portability.
