[0033] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1 and Figure 5 , Figure 1 A schematic diagram of the detector structure of some embodiments of the present disclosure is shown; Figure 5 Shown Figure 1 A partial enlarged schematic diagram of section A in the middle. In some embodiments of the present disclosure, a detector 100 is provided, which may include: an upper housing 101, wherein the edge of the upper housing 101 includes a downwardly protruding upper flange 111; a lower housing 102, wherein the edge of the lower housing 102 includes an upwardly protruding lower flange 112, wherein the upper flange 111 and the lower flange 112 are interlocked, and a glue-containing space is defined between the upper flange 111 and the lower housing 102, and the glue-containing space is filled with a sealing adhesive; and an electronic component 103, which is disposed between the upper housing 101 and the lower housing 102.

[0035] Specifically, in some embodiments, the upper shell 101 and the lower shell 102 can be made of an engineering plastic material with high hardness and good processability, such as polycarbonate. The upper shell 101 and the lower shell 102 can be formed into a generally flat sheet shape, wherein the edge portion of the upper shell 101 protrudes toward one end surface thereof as a whole to form an upper flange 111. Similarly, the circumferential edge of the lower shell 102 protrudes relative to the upper flange 111 to form a lower flange 112. After the upper shell 101 and the lower shell 102 are relatively buckled together, the end surfaces of the upper flange 111 and the lower flange 112 contact each other. The radial inner portion of the upper flange 111 and the lower flange 112 encloses and defines a placement space 110 for placing the electronic component 103 and providing waterproof protection for the electronic component 103.

[0036] In some embodiments, the upper flange 111 of the upper housing 101 and the lower flange 112 of the lower housing 102 are engaged, and a space for sealing adhesive is defined between the upper flange 111 and the lower housing 102. This space is filled with a sealing adhesive to seal the placement space 110 and provide waterproof protection for the electronic components 103 within the placement space 110. Specifically, for example, the upper flange 111 of the upper housing 101 can partially cover the bottom surface of the lower housing 102 along the direction of engagement, and the space between the upper flange 111 and the lower housing 102 can be isolated, with the sealing adhesive disposed within this isolated space. Alternatively, the shape of the end of the lower flange 112 facing the upper housing can be configured so that, after engagement with the upper flange 111, a space for accommodating the sealing adhesive is formed between the lower flange 111 and the lower end of the upper flange 111. The sealing adhesive filled within the space for sealing adhesive can be a material having a sealing function, such as a sealant. The electronic component 103 may be a PCB board, a sensor or other electronic device, which is not specifically limited in some embodiments of the present disclosure. The detector 100 may be any device that requires built-in electronic components for detection functions, such as a detector for detecting human physiological indicators.

[0037] Furthermore, in some embodiments disclosed herein, the radially inner side of the lower end surface of the upper flange 111 has a first sealing groove 111a that is vertically recessed, and the radially inner side of the upper end surface of the lower flange 112 has a first sealing ring 112a that is vertically protruding. The first sealing ring 112a at least partially extends into the first sealing groove 111a, and the two are vertically spaced apart, defining a first adhesive space 120a therebetween. This allows the first adhesive space 120a to be filled with a sealing filler material. This arrangement isolates the placement space 110 formed by the engagement of the upper and lower flanges 111, 112 from the engagement surface between the upper and lower flanges 111, 112, preventing liquids or other contaminants from entering the placement space 110 through the engagement surface between the upper and lower flanges 111, 112. This provides waterproof protection for the electronic components 103 within the placement space 110, enhancing the waterproof performance of the detector 100.

[0038] In some embodiments, the upper flange 111 of the upper housing 101 may further include a sealing lip 111b radially outwardly contacting the end surface of the lower flange 112 of the lower housing 102. The sealing lip 111b may be attached to the upper end surface 112b of the lower flange 112, thereby forming a sealed placement space 110 between the upper housing 101 and the lower housing 102. The radially outwardly contact between the sealing lip 111b and the upper end surface 112b of the lower housing 102 further enhances the waterproof performance of the detector 100.

[0039] In some embodiments, the radial inner side surface of the first sealing groove 111a includes a first bevel 111c, and the first bevel 111c and the radial outer side surface of the first sealing ring 112a jointly define a second glue-containing space 120b, and the second glue-containing space 120b can be connected to the first glue-containing space 120a. As a result, the axial end and the radial outer side of the first sealing ring 112a can be sealed by sealant, thereby greatly increasing the sealing area, thereby further improving the sealing performance. By adding sealant to the first glue-containing space 120a or the second glue-containing space 120b, the added sealant can be squeezed into the other glue-containing space when the upper and lower shells are buckled together. Thus, the sealing of multiple bevels can be completed with one injection, which simplifies the production process and reduces the probability of bubble generation through the natural flow of sealant. It is not only convenient to fill the second glue-containing space 120b and the first glue-containing space 120a with a sealing adhesive having a sealing function, but also can further enhance the waterproof performance of the detector.

[0040] See also Figure 5 , in some embodiments. The first inclined surface 111c can be inclined radially outward from top to bottom, so as to be opposite to the radial outer side surface of the first sealing ring 112a, avoid mutual contact, and jointly define the second glue-containing space 120b, and the second glue-containing space 120b is connected to the first glue-containing space 120a. Some embodiments of the present disclosure do not specifically limit the formation method and specific shape of the second glue-containing space 120b. For example, in some other embodiments, the first inclined surface 111c can also be inclined radially inward from top to bottom, so as to be opposite to the radial outer side surface of the first sealing ring 112a, and jointly define the second glue-containing space 120b, and the second glue-containing space 120b is connected to the first glue-containing space 120a. In this setting, the first inclined surface 111c inclined inward can make the lower end surface of the sealing edge 111b have a larger area, thereby increasing its contact area with the upper end surface 112b of the lower flange 112, and further improving the sealing effect.

[0041] See also Figure 2 and Figure 6 , Figure 2 Schematic diagram of the detector structure of some embodiments of the present disclosure is shown. Figure 6 Shown Figure 2A partially enlarged schematic diagram of portion B in the middle. In some embodiments of the present disclosure, the edge of the upper shell 201 includes an upper flange 211 protruding downward, and the edge of the lower shell 202 includes a lower flange 212 protruding upward. The upper flange 211 and the lower flange 212 are interlocked, and the electronic component 203 is disposed between the upper shell 201 and the lower shell 202. The edge portion of the upper shell 201 protrudes toward one side of its end surface as a whole to form the upper flange 211. Similarly, the circumferential edge of the lower shell 202 protrudes relative to the upper flange 211 to form the lower flange 212. The radial inner side of the lower end surface of the upper flange 211 has a first sealing groove 211a formed by being recessed upward in the vertical direction, and the radial inner side of the upper end surface of the lower flange 212 has a first sealing ring 212a formed by protruding upward in the vertical direction. The radial inner side surface of the first sealing groove 211a includes a first inclined surface 211c, and the radial outer side of the first sealing ring 212a further includes a second inclined surface 212c. The second inclined surface 212c is parallel to the first inclined surface 211c and spaced apart.

[0042] In some embodiments of the present disclosure, the radial outer side surface of the first sealing ring 212a is set as a second inclined surface 212c, and the second inclined surface 212c is parallel to and spaced apart from the first inclined surface 211c, and the two together define a second glue-containing space 220b. The second glue-containing space 220b is connected to the first glue-containing space 220a, which not only facilitates filling the second glue-containing space 220b and the first glue-containing space 220a with a sealing adhesive with a sealing function, but also can further enhance the waterproof performance of the detector.

[0043] In some embodiments of the present disclosure, the radial outer corner of the first sealing groove 211a can be an arc-shaped corner, and the radial outer corner of the first sealing ring 212a can also be an arc-shaped corner. In this way, the sealant in the adjacent glue-containing space can pass more smoothly, and the risk of cracks and breakage can be reduced, thereby improving the service life.

[0044] In some embodiments of the present disclosure, the outer edge of the edge of the upper shell 201 is an arc surface, which is relatively smooth and can reduce the risk of injury caused by sharp angles, thereby preventing users from being scratched when touching it and improving the safety of the detector.

[0045] See also Figure 3 and Figure 7 , Figure 3 Schematic diagram of the detector structure of some embodiments of the present disclosure is shown. Figure 7 Shown Figure 3A partially enlarged schematic diagram of section C in the middle. In some embodiments of the present disclosure, the radially outer side surface of the electronic assembly 303 is spaced apart from the radially inner side of the lower flange 312 and, together with the bottom inner wall of the lower housing 302, forms a groove to define a third adhesive space 330, which is filled with a sealing adhesive. The radially inner side of the upper housing 301 protrudes downward to form a sealing flange 311d, which protrudes downward so that its bottom surface at least partially covers the third adhesive space 330. This provides a two-layer waterproof protective structure between the upper housing 301 and the lower housing 302, further enhancing the detector's waterproof performance.

[0046] In some embodiments, the radially inner side of the lower flange 312 is greater than the radially outer side of the electronic component 303, thereby forming a third adhesive space 330 with different heights on both sides. The third adhesive space 330 can be filled with a sealing adhesive so that the surface of the recessed portion of the third adhesive space 330 is horizontally aligned with the radially outer side of the electronic component 303, while the radially outer side of the sealing flange 311d can be in contact with the radially inner side of the lower flange 312. The bottom surface of the sealing flange 311d can partially cover the third adhesive space 330 while being radially spaced from the outer side of the electronic component 303. Specifically, the width of the sealing flange 311d of the upper housing 301 can be set to be less than the width of the recessed portion of the third adhesive space 330, so that the bottom surface of the sealing flange 311d can partially cover the third adhesive space 330 and be radially spaced from the outer side of the electronic component 303. In some other embodiments, the bottom surface of the sealing flange 311 d may also be configured to at least partially cover the upper surface of the electronic component 303 .

[0047] See also Figure 4 and Figure 8 , Figure 4 Schematic diagram of the detector structure of some embodiments of the present disclosure is shown. Figure 8 Shown Figure 4A partially enlarged schematic diagram of portion D in the middle. In some embodiments of the present disclosure, the radially outer side surface of the electronic component 403 is spaced apart from the radially inner side surface of the lower flange 412 and, together with the bottom inner wall of the lower housing 402, forms a groove to define a fourth adhesive space 430a. The fourth adhesive space 430a is filled with a sealing adhesive, and the bottom surface of the upper flange 411 at least partially covers the third adhesive space 430a. The radially outer side of the upper flange 411 is provided with a sealing surface 411a facing the lower housing 402. This sealing surface 411a abuts the upper end surface of the lower flange 412, and the radially inner side of the sealing surface 411a protrudes downward to form a sealing flange 411b. The radially outer side surface of the sealing flange 411b is spaced apart from the radially inner side surface of the lower flange 412 and, together with the sealing surface 411a, encloses a fifth adhesive space 430b. Thus, the fourth adhesive storage space 430 a and the fifth adhesive storage space 430 b may be configured to communicate with each other, and the communicating spaces may be filled with a sealing adhesive.

[0048] The bottom surface of the sealing flange 411b can at least partially cover the fourth adhesive space 430a, while its radially outer side is adjacent to the fifth adhesive space 430b. As a result, a two-layer waterproof protective structure is provided between the upper shell 401 and the lower shell 402 to further enhance the waterproof performance of the detector. Moreover, by filling the fourth adhesive space 430a or the fifth adhesive space 430b with sealing adhesive, the flow of the sealing adhesive can be used to fill the other adhesive space, further improving the gluing efficiency, simplifying the production process, and reducing the probability of bubble generation through the natural flow of the sealing adhesive.

[0049] In some embodiments, the radially inner side of the lower flange 412 is greater than the radially outer side of the electronic component 403, thereby forming four adhesive spaces 430a with different heights on either side. The fourth adhesive space 430a can be filled with a sealing adhesive, so that the surface of the recessed portion of the fourth adhesive space 430a is horizontally aligned with the radially outer side of the electronic component 403. The lower end surface of the sealing flange 411b can be set flush with the upper surface of the electronic component 403, or slightly lower than the upper surface to extend into the fourth adhesive space 430a. Thus, the lower end surface of the sealing flange 411b at least partially vertically covers the fourth adhesive space 430a, and its radially outer side abuts the fifth adhesive space 430b. This allows the sealing flange 411b to be directly bonded to the sealant between the radially outer side of the electronic component 403 and the radially inner side of the lower flange 412, thereby enhancing the connection strength and sealing effect.

[0050] In some embodiments, the bottom surface of the sealing flange 411b can partially cover the fourth adhesive space 430a, while the radially inner side of the sealing flange 411b is spaced apart from the radially outer side of the electronic component 403. This provides a release opening for the sealing adhesive in the fourth adhesive space 430a and the fifth adhesive space 430b to release excess sealing adhesive or gas within the adhesive space, thereby reducing the possibility of the connector being squeezed out or mixed with bubbles.

[0051] Therefore, because the lower flange 412 no longer needs to have a stepped setting for forming a glue-containing space in the direction of the upper and lower shells being fastened, and the edge of the electronic component 403 is used to form the side wall of the glue-containing space, the height of the lower flange 412 can be reduced, and the electronic component is further fixed by bonding, so that the detector has an increased structural strength while being thinner and more miniaturized overall.

[0052] In some embodiments, the end of the downwardly extending portion of the sealing flange 411b can also be provided with a sealing edge 411c protruding toward the lower shell 402. The protruding sealing edge 411c can, for example, extend into the fourth adhesive space 430a to further increase the contact area between the upper flange 411 and the sealing adhesive, thereby further improving the connection strength and sealing effect.

[0053] Those skilled in the art will appreciate that, although some embodiments have been described above in which a sealing adhesive is used to fill the adhesive space to simultaneously seal the interior and bond the upper and lower shells, the present disclosure does not limit the specific form of the contents of the adhesive space. For example, in some embodiments, the adhesive space described above may be provided with not only a sealing adhesive but also a solid or liquid sealing material such as a sealing ring to further enhance the sealing or connection performance.

[0054] Although a plurality of embodiments of the present disclosure have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Those skilled in the art may conceive of many modifications, changes, and alternatives without departing from the ideas and spirit of the present disclosure. It should be understood that in practicing the present disclosure, various alternatives to some of the embodiments of the present disclosure described herein may be adopted. The appended claims are intended to define the scope of protection of the present disclosure and therefore cover equivalents or alternatives within the scope of these claims.
