[0037] Please see Figure 1 , Figure 3 and Figure 5 The first embodiment of this utility model provides a mobile phone case 1, including a body 2 and a functional module 3. The body 2 has a through hole 21 and a receiving groove 22 on one side of the body 2. The through hole 21 passes through the body 2, and the receiving groove 22 has a mounting groove 221 around the through hole 21. The functional module 3 includes a shell 31. The shell 31 is recessed towards the through hole 21 and forms a placement groove 311 corresponding to the through hole 21. The edge of the placement groove 311 extends outward and forms a mounting part 312 corresponding to the mounting groove 221. The placement groove 311 is embedded in the through hole 21, and the mounting part 312 is embedded in the mounting groove 221. The functional module 3 is mounted on the body 2, and the side away from the receiving groove 22 is exposed through the through hole 21.

[0038] Understandably, when the phone is installed inside the phone case 1, the phone is placed in the receiving slot 22.

[0039] Understandably, the abutting fit between the mounting part 312 and the mounting groove 221 facilitates the fixing of the housing 31 to the side of the body 2 near the receiving groove 22. Since the phone is installed in the receiving groove 22 during the use of the phone case 1, the end of the housing 31 exposed in the receiving groove 22 is abutted by the back cover of the phone, preventing the functional module 3 from moving towards the side of the body 2 near the receiving groove 22 during the use of the phone case 1 and slipping out of it.

[0040] Understandably, the through hole 21 and the mounting groove 221 provide sufficient space for the installation of the functional module 3, preventing the functional module 3 from protruding from the bottom wall of the receiving groove 22. This avoids the extra protrusion thickness from partially lifting the phone placed in the receiving groove 22, causing the phone case 1 to not fit completely with the phone, misaligning the button holes and charging holes around the perimeter, making it difficult for the user to press the buttons or plug in the charging cable, and reducing the protective effect of the phone case 1 on the phone.

[0041] Understandably, some functional modules 3, such as decorative modules, aromatherapy modules, and NFC modules, need to be at least partially external to the main body 2 to achieve better functional effects. The through hole 21 is set through the main body 2, so that the side of the functional module 3 away from the receiving groove 22 is exposed through the through hole 21, which is conducive to the functional module 3 that meets the above conditions to achieve better functional effects and improves the practicality of the phone case 1.

[0042] More specifically, in this embodiment, the through hole 21 is a circular hole and the mounting groove 221 is a circular groove, which improves the integrity and aesthetics of the phone case 1 when the functional module 3 is installed on the body 2.

[0043] Furthermore, the functional module 3 is bonded to the main body 2.

[0044] Understandably, the adhesive connection method improves the tightness of the connection between the functional module 3 and the body 2, reduces the possible shaking of the functional module 3 in the through hole 21 and the mounting groove 221, thereby avoiding abnormal noise caused by the shaking of the functional module 3 when the user uses the phone case 1, which would affect the user's experience.

[0045] Please see Figures 1-4 Furthermore, the functional module 3 includes a sealing cover 32, which covers the mounting groove 221 and the through hole 21.

[0046] Understandably, the sealing cover 32, the through hole 21 and the mounting groove 221 together isolate the functional module 3 in a space that does not come into contact with the mobile phone, preventing the functional module 3 installed on the body 2 from making direct contact with the back cover of the mobile phone, avoiding possible mutual friction between the back cover of the mobile phone and the functional module 3, thereby reducing the scratches or damage that may occur to the back cover of the mobile phone during the use of the mobile phone case 1.

[0047] More specifically, in this embodiment, when the sealing cover 32 is closed, the inner wall of the sealing cover 32 abuts against the edge of the mounting part 312, and the outer wall of the sealing cover 32 abuts against the inner wall of the mounting groove 221, which enhances the tightness of the sealing cover 32 and the body 2, and further enhances the stability of the functional module 3 installed on the body 2.

[0048] Please see Figures 1-5 Furthermore, the depth of the mounting groove 221 is the sum of the thickness of the mounting part 312 and the thickness of the sealing cover 32.

[0049] Understandably, when the phone is placed in the receiving slot 22, if the depth of the mounting slot 221 is large, there will be a gap between the phone back cover and the sealing cover 32. The housing 31 or the sealing cover 32 may wobble during use due to this gap, resulting in abnormal noise or positional displacement. If the depth of the mounting slot 221 is small, the functional module 3 will protrude from the plane of the inner wall of the receiving slot 22 and partially lift the phone, which may cause damage to the phone back cover or misalignment of the holes in the phone case 1 with the phone.

[0050] Understandably, due to the thickness relationship between the mounting groove 221, the mounting part 312 and the sealing cover 32, when the sealing cover 32 covers the mounting groove 221, the side of the sealing cover 32 away from the placement groove 311 and the side of the inner wall of the receiving groove 22 where the mounting groove 221 is provided are on the same plane. This ensures that the area of ​​the inner wall of the receiving groove 22 that the phone back cover contacts when it is placed is a flat plane, avoiding partial lifting of the phone or gaps between the phone and the sealing cover 32.

[0051] Furthermore, a vent hole 313 is provided on the side of the housing 31 away from the placement groove 311; the functional module 3 also includes a fragrance sachet 33, which is installed in the placement groove 311.

[0052] Understandably, functional module 3 is an aromatherapy module that can release fragrance while the user is using the phone case 1, thereby improving the air quality around the phone case 1 and enhancing the user experience.

[0053] Understandably, the vent 313 facilitates the release of the fragrance from the scented sachet 33 into the air, thereby increasing the fragrance diffusion rate.

[0054] Understandably, since the fragrance sachet 33 contains additional chemical components, the sealing cover 32 also prevents the volatile chemicals in the fragrance sachet 33 from remaining on the back of the phone, thus avoiding stains, discoloration, or even partial corrosion on the back of the phone near the functional module 3, thereby improving the safety of the phone case 1.

[0055] Furthermore, the through hole 21 is opened in the middle region of the body 2, and the functional module 3 is correspondingly set in the middle of the body 2.

[0056] When a user holds the phone case 1 that is attached to the phone, their hand usually grips the end of the body 2 closest to the phone's charging port. Understandably, the fact that the through hole 21 is located in the middle area of ​​the body 2 helps to reduce the occurrence of the user's hand blocking the through hole 21.

[0057] Understandably, when functional module 3 is a module with aesthetic function or a module that needs to avoid obstruction in order to achieve its function, the position design of the through hole 21 improves the usability of functional module 3.

[0058] More specifically, in this embodiment, since the fragrance sachet 33 in the functional module 3 needs to release fragrance through the vent 313, the arrangement of the functional module 3 and the through hole 21 in the middle of the body 2 helps to reduce the user's hand from blocking the vent 313, thereby avoiding the situation where the fragrance sachet 33 has difficulty dissipating.

[0059] Furthermore, the central area of ​​the placement groove 311 protrudes towards the sealing cover 32 and forms a mounting post 3111; the incense sachet 33 is provided with a mounting hole 331 corresponding to the mounting post 3111, and the incense sachet 33 is fitted onto the mounting post 3111 through the mounting hole 331.

[0060] Understandably, the mounting post 3111, through its cooperation with the mounting hole 331, fixes the fragrance sachet 33, which is inserted into the placement groove 311, in the exact center of the placement groove 311, so as to prevent the fragrance sachet 33 from shifting in position within the placement groove 311 due to shaking during the use of the phone case 1, thereby preventing abnormal noises from occurring inside the functional module 3.

[0061] More specifically, in this embodiment, the end of the mounting post 3111 that is exposed on the side of the body 2 away from the functional module 3 abuts against the inner wall of the sealing cover 32 to prevent the incense slab 33 from slipping out of the gap between the mounting post 3111 and the inner wall of the sealing cover 32. This would cause the mounting post 3111 to lose its fixing effect on the incense slab 33, and the incense slab 33 would shake in the placement groove 311 and move away from the bottom wall of the placement groove 311, thereby causing abnormal noise or a decrease in the gas diffusion effect of the incense slab 33.

[0062] Furthermore, vent holes 313 are opened around mounting posts 3111.

[0063] Understandably, since the incense slab 33 is fixed in the center of the placement groove 311 by the mounting post 3111, the ventilation holes 313 opened around the mounting post 3111 are conducive to the simultaneous diffusion of the gas of the incense slab 33 from the complete circumference, avoiding excessively high local volatile concentration in one direction or the formation of local gas diffusion dead zones, effectively improving the diffusion uniformity and diffusion efficiency of the gas of the incense slab 33.

[0064] Understandably, the surrounding arrangement of the ventilation holes 313 creates a ring-shaped distribution, forming a decorative ring in visual effect and enhancing the aesthetics of the phone case 1.

[0065] Furthermore, the shell 31 is a transparent shell.

[0066] Understandably, since the side of the functional module 3 away from the receiving slot 22 is exposed to the main body 2, the transparent housing 31 makes its interior visible, and the user can directly observe the items placed in the placement slot 311 from the other side of the main body 2 where the receiving slot 22 is opened.

[0067] Understandably, when decorative items are placed in the slot 311, the transparent shell 31 makes it easy to fully display the decorations to improve the aesthetics of the phone case 1; when items that allow for a direct assessment of the real-time status are placed in the slot 311, such as the air freshener 33 whose remaining amount can be observed with the naked eye, the user can determine whether the air freshener 33 needs to be replaced without removing it, thus improving the usability of the phone case 1.

[0068] Furthermore, a magnetic absorbing element 23 is provided on the side of the main body 2 away from the mounting groove 221. The magnetic absorbing element 23 is a ring-shaped magnetic absorbing element, and the exposed part of the functional module 3 is located inside the ring of the magnetic absorbing element 23.

[0069] More specifically, in this embodiment, the magnetic element 23 is a MagSafe magnetic ring.

[0070] Understandably, the magnetic attachment 23 adds magnetic functionality to the phone case 1, improving its practicality; at the same time, the positioning of the magnetic attachment 23 and the functional module 3 enhances the overall visual appeal of the phone case 1, improving its aesthetics.

[0071] Compared with the prior art, the mobile phone case of this utility model has the following advantages: 1. The mobile phone case of this utility model includes a body and a functional module.
