[0038] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0039] For the purpose of clear description and easy understanding, in the following description, the side of the detector in contact with the human body is regarded as the vertical lower side of the detector, the side of the detector away from the human body is regarded as the vertical upper side of the detector, the direction parallel to the surface of the detector in contact with the human body is regarded as the horizontal direction, the direction along the horizontal direction towards the detection needle of the detector is regarded as the radial direction inwards, and the direction along the horizontal direction away from the center of the detection needle of the detector is regarded as the radial direction outwards. The position of other related components is described based on the above description, unless otherwise specified. The above description is only used for providing a reference direction for describing the relative position relationship of the structures, and is not a limitation on the actual arrangement of the structures of the embodiments of the present disclosure.

[0040] Referring to FIG. 1 and FIG. 5, FIG. 1 shows a schematic diagram of the structure of the detector according to some embodiments of the present disclosure, and FIG. 5 shows a partial enlarged schematic diagram of part A in FIG. 1. In some embodiments of the present disclosure, a detector 100 is provided, which can include an upper shell 101, a lower shell 102, and a bottom surface 105. The bottom surface 105 is the surface in contact with the human body (user). The edge of the upper shell 101 includes an upper flange 111 protruding downward, and the edge of the lower shell 102 includes a lower flange 112 protruding upward. The upper flange 111 is engaged with the lower flange 112, and a sealing space is formed between the upper flange 111 and the lower shell 102, which is filled with a sealing material. A detection circuit 103 is arranged between the upper shell 101 and the lower shell 102.

[0041] In the embodiments described in FIG. 1 and FIG. 5, the upper shell 101 and the lower shell 102 can be made of engineering plastic materials with high hardness and good processability, such as polycarbonate. The upper shell 101 and the lower shell 102 are both substantially flat and plate-shaped, for example, and the edge of the upper shell 101 is integrally protruded towards the end surface thereof (i.e. towards the bottom surface 105, or downwards) to form the upper flange 111. Similarly, the circumferential edge of the lower shell 102 is protruded opposite to the upper flange 111 to form the lower flange 112, i.e. the lower flange 112 extends upwards away from the bottom surface 105. After the upper shell 101 and the lower shell 102 are engaged with each other, the end surfaces of the upper flange 111 and the lower flange 112 are in contact with each other. After the upper flange 111 and the lower flange 112 are coupled, a placement space 110 is formed along the radial direction of the upper shell 101 and the lower shell 102 for placing the detection circuit 103, which is waterproofed.

[0042] In some embodiments, the upper flange 111 of the upper housing 101 is buckled with the lower flange 112 of the lower housing 102, and a sealing space is formed between the upper flange 111 of the upper housing 101 and the lower housing 102, which is filled with a sealing material for sealing the placement space 110 and waterproofing the detection circuit 103 in the placement space 110. Specifically, the upper flange 111 of the upper housing 101 covers the bottom surface of the lower housing 102 partially along the buckling direction and is isolated therefrom to form a sealing space for the sealing material. Optionally, the end of the lower flange 112 towards the upper housing is shaped such that, after buckling with the upper flange 111, a filling space for the sealing material is formed between the outer wall of the lower flange 112 and the inner wall of the upper flange 111 (e.g., the inner wall of the lower end). The sealing material in the sealing space is a sealing adhesive. The sealing adhesive can be any material that can seal and waterproof the upper flange 111 and the lower flange 112, and embodiments of the present disclosure do not make specific limitations thereon. For example, the sealing adhesive can be a sealant, a gasket, a seal ring, hot melt adhesive, or any other material with sealing function.

[0043] The detection circuit 103 can be a PCB board, a sensor, or any other electronic device, and embodiments of the present disclosure do not make specific limitations thereon. The detector 100 can be any device that needs to have a built-in detection circuit for detection function, such as a detector for detecting physiological indicators of the human body. Preferably, the detection circuit 103 is provided with a sensor and a processor. Optionally, the detection circuit 103 is further provided with an antenna or any other wireless transceiver device. In addition, the detector 100 can further include a detection needle assembly 150. The detection needle assembly 150 passes through the upper housing 101 and the lower housing 102 in the up-down direction. The detection needle assembly 150 includes a detection needle 152. In use, the bottom surface of the detector 100 is attached to the skin of a user, and the detection needle 152 penetrates the skin to collect physiological information of the human body. Preferably, the physiological information is blood glucose information. Optionally, the physiological information can be at least one of blood glucose information, adrenaline information, cholesterol information, muscle electricity information, or temperature information. The detection needle 152 is connected to the detection circuit 103. The sensor of the detection circuit 103 converts the physiological information into corresponding physiological signals / data, and the processor processes the physiological data and obtains corresponding physiological indicators (e.g., blood glucose indicators, adrenaline indicators in blood, cholesterol indicators in blood, muscle electricity indicators, temperature indicators, etc.) based on the physiological data. Optionally, the detection circuit 103 can send the physiological indicators to an external receiving device through the transceiver device.

[0044] Optionally, in some embodiments of the present disclosure, the radially inner side of the lower end surface of the upper flange 111 has a first sealing groove 111a formed by being concave upward in the vertical direction, and the radially inner side of the upper end surface of the lower flange 112 has a first sealing ring 112a formed by being convex upward in the vertical direction. The first sealing ring 112a at least partially extends into the first sealing groove 111a, and the two are spaced apart in the vertical direction, and a first sealing space 120a is defined between the two, so that the first sealing space 120a can be filled with a sealing material having a sealing function. According to such an arrangement, the placement space 110 formed after the upper flange 111 and the lower flange 112 are buckled can be isolated from the buckling contact surface of the upper flange 111 and the lower flange 112, so that liquid or other contaminants cannot enter the placement space 110 from the buckling contact surface of the upper flange 111 and the lower flange 112, thereby being able to waterproof the detection circuit 103 in the placement space 110 and enhancing the waterproof performance of the detector 100.

[0045] The upper flange 111 of the upper shell 101 can further include a sealing edge 111b in contact with the end surface of the lower flange 112 of the lower shell 102 on the radially outer side. The sealing edge 111b can be attached to the upper end surface 112b of the lower flange 112, so that the upper shell 101 and the lower shell 102 form a sealed placement space 110. The radially outer side of the upper shell 101 and the lower shell 102 is also sealed by the sealing edge 111b and the upper end surface 112b of the lower shell 102, to further enhance the waterproof performance of the detector 100.

[0046] The radially inner side of the first sealing groove 111a includes a first inclined surface 111c, which cooperates with the radially outer side of the first sealing ring 112a to define a second sealing space 120b, which can be in communication with the first sealing space 120a. Thus, the axial end and the radially outer side of the first sealing ring 112a can be sealed by the sealant, thereby greatly increasing the sealing area and further improving the sealing performance. By filling the sealant into one of the first sealing space 120a or the second sealing space 120b, the filled sealant can be squeezed into the other sealing space when the upper and lower shells are buckled, thereby enabling the sealing of multiple inclined surfaces to be completed by a single injection of sealant, simplifying the production process and reducing the probability of air bubbles. Not only is it convenient to fill the second sealing space 120b and the first sealing space 120a with a sealing material having a sealing function, but it also further enhances the waterproof performance of the detector.

[0047] Referring to FIG. 5, in some embodiments, the first inclined surface 111c can be inclined from top to bottom to the radial outer side, so as to be opposite to the radial outer side of the first sealing ring 112a, and to jointly define the second sealing space 120b which is in communication with the first sealing space 120a. The present disclosure does not make specific limitation to the forming manner and specific shape of the second sealing space 120b. For example, in some embodiments, the first inclined surface 111c can also be inclined from top to bottom to the radial inner side, so as to be opposite to the radial outer side of the first sealing ring 112a, and to jointly define the second sealing space 120b which is in communication with the first sealing space 120a. In this arrangement, the first inclined surface 111c which is inclined to the inner side can make the lower end surface of the sealing rib 111b have a larger area, so as to increase the contact area between the lower end surface 112b of the lower flange 112, and to further improve the sealing effect.

[0048] FIG. 2 shows a schematic diagram of a detector structure according to another embodiment of the present disclosure, and FIG. 6 shows a partial enlarged schematic diagram of part B in FIG. 2. The detector 200 in FIG. 2 comprises a bottom surface 205, an upper housing 201, a lower housing 202, a detection circuit 203, and a detection needle assembly 250.

[0049] The detection circuit 203 can be a PCB board, a sensor, or other electronic device, and the embodiments of the present disclosure do not make specific limitation thereto. The detector 200 can be various devices which need to be built-in with a detection circuit for detection function, such as a detector for detecting physiological indexes of a human body, etc. Preferably, the detection circuit 203 is provided with a sensor and a processor. Optionally, the detection circuit 203 is further provided with an antenna or other wireless transceiving device. In addition, the detector 200 can further comprise the detection needle assembly 250. The detection needle assembly 250 passes through the upper housing 201 and the lower housing 202 in the up-down direction. The detection needle assembly 250 comprises a detection needle 252. In use, the bottom surface of the detector 200 is attached to the skin of a user, and the detection needle 252 pierces into the subcutaneous tissue to collect physiological information of the human body. Preferably, the physiological information is blood glucose information. Optionally, the physiological information can also be at least one of blood glucose information, adrenaline information, cholesterol information, muscle electricity information, or temperature information of the user. The detection needle 252 is connected to the detection circuit 203. The sensor of the detection circuit 203 converts the above-mentioned physiological information into corresponding physiological signals / data, and then the processor processes the physiological data, and obtains corresponding physiological indexes (such as blood glucose index, adrenaline index in blood, cholesterol index in blood, muscle electricity index, temperature index, etc.) based on the physiological data. Optionally, the detection circuit 203 can also send the above-mentioned physiological indexes to an external receiving device through the transceiving device.

[0050] The edge of the upper shell 201 comprises an upper flange 211 protruding downward, the edge of the lower shell 202 comprises a lower flange 212 protruding upward, the upper flange 211 and the lower flange 212 are buckled, and the detection circuit 203 is arranged between the upper shell 201 and the lower shell 202. The edge portion of the upper shell 201 protrudes integrally to the side of the end face to form the upper flange 211, and similarly, the circumferential edge of the lower shell 202 protrudes opposite to the upper flange 211 to form the lower flange 212. The radially inner side of the lower end face of the upper flange 211 has a first sealing groove 211a formed by being concave upward in the vertical direction, and the radially inner side of the upper end face of the lower flange 212 has a first sealing ring 212a formed by being convex upward in the vertical direction. The radially inner side of the first sealing groove 211a comprises a first inclined surface 211c, and the radially outer side of the first sealing ring 212a further comprises a second inclined surface 212c, which is parallel to and spaced apart from the first inclined surface 211c.

[0051] In FIG. 2, the radially outer side of the first sealing ring 212a is provided with a second inclined surface 212c, which is parallel to and spaced apart from the first inclined surface 211c, and together defines a second sealing space 220b between the two, which is in communication with the first sealing space 220a. Not only is it convenient to fill the second sealing space 220b and the first sealing space 220a with sealing material having sealing function, but it can also further enhance the waterproof performance of the detector.

[0052] In FIG. 2, the corner of the radially outer side of the first sealing groove 211a can be an arc-shaped corner, and the corner of the radially outer side of the first sealing ring 212a can also be an arc-shaped corner. In this way, the sealing glue in the adjacent sealing space can pass more smoothly, and the risk of cracking and breaking can be reduced, and the service life can be improved.

[0053] 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 corners, thereby avoiding scratches when the user touches it and improving the safety of the detector.

[0054] The structures not introduced in FIG. 2 and FIG. 6 are the same as the corresponding structures in FIG. 1 and FIG. 5, and will not be described here.

[0055] FIG. 3 shows a schematic diagram of the structure of a detector according to another embodiment of the present disclosure, and FIG. 7 shows a partially enlarged schematic diagram of part C in FIG. 3. The detector 300 in FIG. 3 comprises a bottom surface 305, an upper shell 301, a lower shell 302, a detection circuit 303, and a detection needle assembly 350.

[0056] The detection circuit 303 can be a PCB board, a sensor, or other electronic device, and embodiments of the present disclosure do not make specific limitations thereon. The detector 300 can be various devices that need to be equipped with a built-in detection circuit for detection functions, such as a detector for detecting physiological indicators of a human body, and the like. Preferably, the detection circuit 303 is provided with a sensor and a processor. Optionally, the detection circuit 303 is further provided with an antenna and other wireless transceiving devices. In addition, the detector 300 can further include a detection needle assembly 350. The detection needle assembly 350 penetrates the upper housing 301 and the lower housing 302 in the up-down direction. The detection needle assembly 350 includes a detection needle 352. In use, the bottom surface of the detector 300 is attached to the skin of a user, and the detection needle 352 penetrates the skin to collect physiological information of the human body. Preferably, the physiological information is blood glucose information. Optionally, the physiological information can also be at least one of blood glucose information, adrenaline information, cholesterol information, muscle electricity information, or temperature information of the user. The detection needle 352 is connected to the detection circuit 303. The sensor of the detection circuit 303 converts the physiological information into corresponding physiological signals / data, and then the processor processes the physiological data and obtains corresponding physiological indicators (such as blood glucose indicators, adrenaline indicators in blood, cholesterol indicators in blood, muscle electricity indicators, temperature indicators, and the like) based on the physiological data. Optionally, the detection circuit 303 can also send the physiological indicators to external receiving devices through the transceiving devices.

[0057] In some embodiments of the present disclosure, the side surface of the detection circuit 303 radially outward is spaced apart from the radially inner side of the lower flange 312 and cooperates with the inner wall of the bottom of the lower housing 302 to form a groove to define a third sealed space 330, and the third sol space 330 is filled with a sealing material; the radially inner side of the upper housing 301 is downwardly protruding to form a protrusion 311d, and the protrusion 311d is downwardly protruding so that its bottom surface can at least partially cover the third sealed space 330. In this way, two layers of waterproof protection structures can be provided between the upper housing 301 and the lower housing 302 to further enhance the waterproof performance of the detector.

[0058] In some embodiments, the height of the radially inner side of the lower flange 312 is greater than the height of the side radially outside the detection circuit 303, thus forming two portions of the third sealed space 330 with different heights. The third sealed space 330 can be filled with a sealing material to make the surface of the recessed portion of the third sealed space 330 horizontally aligned with the side radially outside the detection circuit 303, and the radially outer side of the convex portion 311d can be attached to the radially inner side of the lower flange 312. The bottom surface of the convex portion 311d can partially cover the third sealed space 330 and be spaced apart from the outer side of the detection circuit 303 in the radial direction. Specifically, the width of the convex portion 311d of the upper housing 301 can be set to be less than the width of the recessed portion of the third sealed space 330, so that the bottom surface of the convex portion 311d can partially cover the third sealed space 330 and be spaced apart from the outer side of the detection circuit 303 in the radial direction. In some other embodiments, the bottom surface of the convex portion 311d can also be set to at least partially cover the upper surface of the detection circuit 303.

In addition, the detector 400 can further include a detection needle assembly 450. The detection needle assembly 450 penetrates the upper housing 401 and the lower housing 402 in the up-down direction. The detection needle assembly 450 includes a detection needle 452. In use, the bottom surface of the detector 400 is attached to the skin of a user, and the detection needle 452 penetrates the skin to collect physiological information of the human body. Preferably, the physiological information is blood glucose information. Optionally, the physiological information can also be at least one of blood glucose information, adrenaline information, cholesterol information, muscle electrical information, or temperature information of the user. The detection needle 452 is connected to the detection circuit 403. The sensor of the detection circuit 403 converts the physiological information into corresponding physiological signals / data, and then the processor processes the physiological data and obtains corresponding physiological indicators (such as blood glucose indicators, adrenaline indicators in blood, cholesterol indicators in blood, muscle electrical indicators, temperature indicators, and the like) based on the physiological data. Optionally, the detection circuit 403 can also transmit the physiological indicators to an external receiving device through the transceiver.

[0062] In some embodiments of the present disclosure, the side surface of the detection circuit 403 radially outward is spaced apart from the radially inner side of the lower flange 412 and cooperates with the inner wall of the bottom of the lower housing 402 to form a groove to define a fourth sealed space 430a, the fourth sol space 430a is filled with a sealing material, and the bottom surface of the upper flange 411 at least partially covers the third sol space 430a; and the radially outer side of the upper flange 411 is provided with a sealing surface 411a facing the lower housing 402, the 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 protrusion 411b. The radially outer side surface of the protrusion 411b is spaced apart from the radially inner side of the lower flange 412 and cooperates with the sealing surface 411a to define a fifth sealed space 430b. Thus, the fourth sealed space 430a and the fifth sealed space 430b can be arranged to be in communication with each other, and the communication space can be filled with a sealing material.

[0063] The bottom surface of the convex portion 411b can at least partially cover the fourth sealing space 430a, and the radially outer side surface thereof can abut the fifth sealing space 430b. In this way, two layers of waterproof protection structures are arranged between the upper housing 401 and the lower housing 402, so as to further enhance the waterproof performance of the detector. By filling the fourth sealing space 430a or the fifth sealing space 430b with the sealing material, the sealing material can be filled into the other sealing space by means of the flow of the sealing material, so as to further improve the gluing efficiency, simplify the production process, and reduce the probability of air bubbles by means of the natural flow of the sealing material.

[0064] In some embodiments, the radially inner side surface of the lower flange 412 has a height greater than that of the radially outer side surface of the detection circuit 403, so that the two side portions of the fourth sealing space 430a formed thereby have different heights. The fourth sealing space 430a can be filled with the sealing material to make the surface of the recessed portion of the fourth sealing space 430a horizontally aligned with the side surface of the radially outer side of the detection circuit 403. The lower end surface of the convex portion 411b can be arranged to be flush with the upper surface of the detection circuit 403 or slightly lower than the upper surface to extend into the fourth sealing space 430a. In this way, the lower end surface of the convex portion 411b at least partially covers the fourth sealing space 430a in the vertical direction, and the radially outer side surface thereof abuts the fifth sealing space 430b. The sealing glue between the convex portion 411b and the radially outer side of the detection circuit 403 and the radially inner side of the lower flange 412 is directly bonded and connected, so as to increase the connection strength and the sealing effect.

[0065] In some embodiments, the bottom surface of the convex portion 411b can partially cover the fourth sealing space 430a, and the radially inner side of the convex portion 411b is arranged to be spaced apart from the radially outer side of the detection circuit 403. In this way, a release opening can be provided for the sealing material in the fourth sealing space 430a and the fifth sealing space 430b to release the excess sealing material or the gas in the sealing space, so as to reduce the situation of the connection agent being extruded out or mixed with air bubbles.

[0066] In this way, because the lower flange 412 no longer needs to have a stepped arrangement for forming the sealing space in the direction of the upper and lower housings being buckled, and the edge of the detection circuit 403 is used to constitute the side wall of the sealing space, the height of the lower flange 412 can be reduced, and the detection circuit is further fixed by bonding, so that the detector has increased structural strength while being thinner and more miniaturized as a whole.

[0067] In some embodiments, the end portion of the downwardly extending portion of the convex portion 411b can further be provided with a convex sealing edge 411c facing the lower housing 402, which can extend into the fourth sealing space 430a, for example, so as to further increase the contact area of the upper flange 411 with the sealing material, thereby further improving the connection strength and the sealing effect.

[0068] The structures not introduced in FIGS. 4 and 8 that are the same as the corresponding structures in FIGS. 1, 2, 3, 5, 6, and 7 are not described here again.

[0069] Those skilled in the art can understand that, although some of the above describes filling the sealing space with sealing material to simultaneously play the effect of internal sealing and bonding the upper and lower housings, the present disclosure does not limit the specific form of the content in the sealing space. For example, in some embodiments, not only can the sealing material be arranged in the sealing space described above, but also solid or liquid sealing substances such as sealing rings can be arranged to further enhance the sealing or connection performance.

[0070] Although the embodiments of the present disclosure have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Many changes, modifications, and alternatives will be apparent to those skilled in the art without departing from the spirit and scope of the present disclosure. It should be understood that various alternatives to the embodiments of the present disclosure described herein can be employed in practicing the present disclosure. The appended claims are intended to define the scope of the present disclosure and thus cover any equivalents or alternatives within the scope of these claims.
