[0002] In existing refrigerators, one or more lights are typically installed on the top or side of the inner liner. However, due to the obstruction of items on the shelves, there are areas inside the inner liner that are not illuminated by these lights. Related technologies often incorporate lights on the shelves themselves. The electrical connection between the lights on the shelves and the power electrodes on the inner liner can utilize contact-based methods such as plugging and unplugging, or contactless methods such as wireless power supply. Since the shelves are usually removable and adjustable, they can move slightly within the inner liner. For wireless power supply connections, this movement can alter the transmit / receive distance, resulting in energy loss and affecting the illumination of the lights on the shelves.

[0043] This utility model proposes a refrigerator.

[0044] Please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 In one embodiment of the present invention, the refrigerator includes:

[0045] The shell (not shown) and the inner liner 100 are disposed in the shell and the inner liner 100 includes a plurality of vertically extending inner walls 130.

[0046] Shelf 200, detachably connected to inner wall 130 via a limiting structure, and equipped with lighting module 230; and

[0047] A wireless power supply device (not shown in the figure) includes a transmitting module 300 and a receiving module 400. The transmitting module 300 is located on the inner wall 130, and the receiving module 400 is located on the shelf 200 and is opposite to the transmitting module 300 in a first direction. The receiving module 400 is electrically connected to the lighting module 230.

[0048] Among them, the shelf 200 and the inner wall 130 are fixed together in the first direction by a limiting structure.

[0049] The technical solution of this utility model involves setting a transmitting module 300 on the inner wall 130 of the inner liner 100 and a receiving module 400 on the shelf 200, with the transmitting module 300 and the receiving module 400 facing each other in a first direction. Simultaneously, the shelf 200 is detachably connected to the inner wall 130 via a limiting structure, which maintains a fixed relationship between the shelf 200 and the inner wall 130 in the first direction. Since the inner wall 130 is part of the inner liner 100, and the transmitting module 300 is mounted on the inner wall 130, the inner wall 130 can remain stable relative to the transmitting module 300. Combined with the shelf 200 and the inner wall 130 remaining fixed in the first direction, at least the shelf 200 is prevented from swaying in the first direction within the inner liner 100. This ensures the stability of the gap between the transmitting module 300 and the receiving module 400, reduces energy loss during wireless power supply, ensures the efficiency and stability of wireless power supply, and further guarantees the lighting effect of the lighting module 230 on the shelf 200.

[0050] It should be noted that the shelf 200 and the transmitting module 300 can be connected to the same or two parallel inner walls 130. In this case, the first direction is understood as the distribution direction of the shelf 200 and the inner wall 130 it is connected to, which is also the distribution direction of the transmitting module 300 and the receiving module 400. The limiting structure keeps the shelf 200 fixed relative to the inner liner 100 in the direction of assembly / disassembly of the shelf 200, i.e., the first direction. Alternatively, the shelf 200 and the transmitting module 300 can also be connected to two intersecting inner walls 130. In this case, the first direction is only understood as the distribution direction of the transmitting module 300 and the receiving module 400. The limiting structure keeps the shelf 200 fixed relative to the inner liner 100 in the direction of intersection or even perpendicular to the direction of assembly / disassembly of the shelf 200, i.e., the first direction. Furthermore, the transmitting module 300 is electrically connected to an external power source through the housing. This connection can be independent or achieved through the refrigerator's existing electrical connection structure.

[0051] In one embodiment, please refer to Figure 1 and Figure 2The inner liner 100 has an opening 120 on one side. The inner wall 130 includes a bottom wall 132 opposite to the opening 120 and side walls 131 on the left and right sides of the opening 120. The transmitting module 300 is disposed on the side wall 131, and the shelf 200 is detachably connected to the bottom wall 132 through a limiting structure. It can be understood that the left and right sides of the opening 120, with reference to the use state of the inner liner 100, are adjacent to and connected to the inner wall 130 of the opening 120. The first direction is the distribution direction of the two side walls 131. The disassembly and assembly directions of the shelf 200 intersect or are even perpendicular to the first direction. The limiting structure can avoid excessive limiting and fixing of the shelf 200 in the disassembly and assembly directions, which is convenient for users to disassemble and assemble the shelf 200, and also helps to ensure the stability of the shelf 200 relative to the side wall 131 in the first direction. Furthermore, the shelf 200 is connected to the bottom wall 132, which allows for more space for disassembly and assembly using the inner liner 120, reducing the difficulty of disassembling and assembling the shelf 200. The two side walls 131, located opposite each other along the first direction, are configured as the left and right side walls of the inner liner 100. Of course, in other embodiments, the shelf 200 can also be detachably connected to the side walls 131 via a limiting structure, and the launching module 300 can also be located on the bottom wall 132, in which case the first direction is configured as the distribution direction of the inner liner 120 and the bottom wall 132.

[0052] It should be noted that the bottom wall 132 intersects the side wall 131, either directly or indirectly, resulting in the plane containing the side wall 131 and the plane containing the bottom wall 132 intersecting. Furthermore, the shape of the shelf 200 is adapted to the distribution of the walls, including the side wall 131 and bottom wall 132, within the inner liner 100. The shelf 200 is placed horizontally on the inner liner 100, which has an opening 120. The side wall 131 can be located adjacent to the periphery of the opening 120, while the bottom wall 132 faces the opening 120 directly or at an angle. Alternatively, the side wall 131 may face the opening 120 directly or at an angle, while the bottom wall 132 may be adjacent to the opening 120.

[0053] In one embodiment, please refer to Figure 2 , Figure 7 and Figure 9The limiting structure includes a hook 500 disposed on the bottom wall 132 and a hook portion 240 disposed on the shelf 200, with the hook portion 240 hooked to the hook 500. It can be understood that the shelf 200 is connected to the bottom wall 132 by hooking, improving the ease of installation of the shelf 200. Furthermore, when the side wall 131 and the bottom wall 132 are configured as the inner wall 130 of the inner liner 100 extending vertically, the hook portion 240 is vertically hooked to the hook 500, adapting the shelf 200 to the shape of the inner liner 100 in the horizontal direction, and facilitating installation operations using the vertical space of the inner liner 100, further improving the ease of installation of the shelf 200. Since the shelf 200 and the side wall 131 are fixed relative to each other in a first direction, the hook-on part 240 and the hook-on piece 500 also need to be fixed relative to each other in a first direction. This first direction intersects with or is even perpendicular to the hook-on direction of the shelf 200, thereby ensuring that the shelf 200 can be fixed relative to the side wall 131 in the first direction after hooking. Please refer to [link / reference here]. Figure 1 and Figure 5 The first direction is set to horizontal. Of course, in other embodiments, the shelf 200 can also be connected to the inner liner 100 by means of snap-fit, plug-in or other detachable methods.

[0054] Furthermore, in this embodiment, please refer to Figure 1 , Figure 4 and Figure 9The mounting member 500 is provided with a mounting hole 510, and the mounting part 240 abuts against at least a portion of the hole wall of the mounting hole 510 in a first direction. It is understood that the mounting hole 510 can extend in a direction intersecting the first direction, so that the mounting part 240 can abut against the hole wall of the mounting hole 510 on the opposite side in the first direction, thereby limiting the stability of the mounting part 240 relative to the mounting member 500 in the first direction, thereby ensuring the stability of the shelf 200 in the inner liner 100 along the first direction, and thereby ensuring the stability of the gap between the receiving module 400 and the transmitting module 300 on the shelf 200. Specifically, when the shelf 200 is vertically attached to the bottom wall 132, after the attachment part 240 is attached to the attachment hole 510, the upper part of the attachment part 240 may abut against the wall of the attachment hole 510 in the first direction, or the lower part of the attachment part 240 may abut against the wall of the attachment hole 510 in the first direction, or the attachment part 240 may abut against the corresponding wall of the attachment hole 510 in the first direction at all points in the vertical direction. Of course, in other embodiments, the mounting member 500 may have an abutment portion provided at the position of the mounting hole 510. After the mounting part 240 is mounted on the mounting hole 510, the abutment portion abuts against the opposite sides of the mounting part 240 or the shelf 200 in the first direction to ensure the stability of the shelf 200 in the first direction, thereby ensuring the stability of the gap between the transmitting module 300 and the receiving module 400; or, the shelf 200 may have a mounting hole 510, the mounting part 240 may be provided on the bottom wall 132, and at least a portion of the hole wall of the mounting part 240 and the mounting hole 510 may abut against each other in the first direction.

[0055] Regarding the shape of the mounting hole 510, in one embodiment, please refer to... Figures 4 to 6 , Figure 9The mounting hole 510 includes a snap-in section 511 and a mounting section 512 distributed sequentially from top to bottom. In the first direction, the width of the snap-in section 511 is greater than the width of the mounting section 512. The larger width of the snap-in section 511 allows the mounting part 240 to be smoothly inserted at a certain angle or deviation, and can guide the mounting part 240 to be mounted on the mounting section 512, reducing the difficulty for the user to adjust the position of the shelf 200. As for the mounting section 512, after the mounting part 240 slides into the mounting section 511, referring to the above-mentioned at least part of the hole wall of the mounting part 240 and the mounting hole 510 abutting in the first direction, it can be seen that the mounting section 512 can abut the mounting part 240 in the first direction. On the one hand, this allows the mounting part 240 to remain stable within the mounting hole 510, thus ensuring the stability of the shelf 200. On the other hand, it also ensures the stability of the gap between the transmitting module 300 and the receiving module 400 on the shelf 200. In this embodiment, at the connection between the snap-in section 511 and the hook-up section 512, the width of the hook-up hole 510 gradually decreases from top to bottom, reducing the abruptness of the hook-up part 240 sliding from the snap-in section 511 into the hook-up section 512. Of course, in other embodiments, the widths of the snap-in section 511 and the hook-up section 512 may be equal, but the snap-in section 511 and the hook-up section 512 may be vertically misaligned, so that one side of the hole wall of the snap-in section 511 abuts against one side of the hook-up part 240 in the first direction, and the other side of the hole wall of the hook-up section 512 abuts against the other side of the hook-up part 240 in the first direction.

[0056] In one embodiment, please refer to Figure 5 , Figure 6 , Figure 8 and Figure 9The limiting structure also includes a balance hole 520 provided on the hanger 500 and an insertion protrusion provided on the shelf 200. The balance hole 520 is located below the hanger 510, and the insertion protrusion 250 is located below the only hanger 240 and inserted into the balance hole 520. It is understood that the shelf 200 has a hanging part 240 on one side opposite the bottom wall 132, so that one side of the shelf 200 is hung on the bottom wall 132, and the rest is suspended. In this way, after the insertion protrusion 250 is inserted into the balance hole 520, it forms a second support for the shelf 200. Together with the hanging hole 510 and the hanging part 240, it forms a double-support limit structure. On the one hand, when the shelf 200 is subjected to external force and vibrates, the two support points formed by the hanging part 240 and the insertion protrusion in the vertical direction work together to prevent the shelf 200 from tilting or swaying, further improving the stability of the shelf 200, thereby ensuring the gap stability between the transmitting module 300 and the receiving module 400. On the other hand, the lower insertion protrusion 250 is located on the lower side of the upper partition 220 of the shelf 200, providing lower support for the shelf 200 and improving the load-bearing capacity of the shelf 200. In this embodiment, the wall of the balancing hole 520 in the first direction abuts against the opposite side of the insertion protrusion 250 in the first direction. Of course, in other embodiments, another hanging structure can also be provided above the hanging hole 510, and the shelf 200 can be provided with a corresponding hanging structure above the hanging part 240. The hanging structure of the shelf 200 is connected to the hanging structure on the bottom wall 132, so that the shelf 200 forms a double hanging force receiving point in the vertical direction, thereby improving the stability of the shelf 200.

[0057] Furthermore, in this embodiment, please refer to Figure 1 , Figure 4 and Figure 9The mounting holes 510 and balancing holes 520 form a group. The mounting component 500 includes multiple groups of mounting holes 510 and balancing holes 520 distributed vertically at intervals. It can be understood that one group of mounting holes 510 and balancing holes 520 corresponds to one shelf 200. The multiple groups of mounting holes 510 and balancing holes 520 distributed vertically at intervals provide connection points for adjusting the vertical position of the shelf 200, thereby meeting the needs of adjusting the shelf 200's position. Combined with the mounting holes 510, the shelf 200 and the bottom wall 132 can be relatively fixed in the first direction, thereby ensuring a stable gap between the receiving module 400 and the corresponding transmitting module 300 on the shelf 200. This ensures that the wireless power supply device generates only low energy loss in any position of the shelf 200, guaranteeing the lighting effect of the lighting module 230. In this design, for different sets of mounting holes 510 and balancing holes 520, the straight lines formed by their vertical distribution are perpendicular to the first direction. This ensures that the gaps between the receiving module 400 and the transmitting module 300 in any vertical shelf 200 are approximately equal, thereby guaranteeing the uniformity of the lighting effect on different shelves 200 on the inner liner 100. Alternatively, depending on the different lighting requirements, such as a higher lighting brightness in the vertical center and a lower brightness on the sides, the mounting holes 510 and balancing holes 520 in the vertical center are positioned closer to the side wall 131 along the first direction. In other embodiments, only one set of mounting holes 510 and balancing holes 520 may be provided, and a lighting module 230 and a receiving module 400 may be provided on the shelf 200 corresponding to this set of mounting holes 510 and balancing holes 520. By setting the illumination range of the lighting module 230, the central part of the inner liner 100 can be illuminated.

[0058] Regarding the arrangement of multiple sets of mounting holes 510 and balancing holes 520, please refer to the following in this embodiment: Figures 1 to 3The transmitting module 300 includes multiple transmitting units 301, which are distributed vertically at intervals. The receiving module 400 selects one transmitting unit 301 to be adjacent to it. The spacing between the mounting holes 510 and the balancing holes 520 of two adjacent groups is adapted to the spacing between the two adjacent transmitting units 301. It can be understood that the distance between two adjacent sets of hanging holes 510 and balance holes 520 is: the distance between one set of hanging holes 510 and balance holes 520 and the adjacent set of hanging holes 510 and balance holes 520. When any shelf 200 is adjusted to any layer, the receiving module 400 on it can be aligned with a specific transmitting unit 301. The multiple transmitting units 301 of the transmitting module 300 can independently complete wireless power supply with the receiving module 400, presenting multiple wireless power supply transmitting positions vertically distributed by the transmitting module 300 with multiple transmitting units 301. This ensures that any shelf 200 can achieve wireless lighting through the wireless power supply device. When multiple shelves 200 are set in the inner liner 100, the brightness of the inner liner 100 is ensured, or it is convenient to adjust the position of the shelf 200. In this design, different transmitting units 301 on the transmitting module 300 can have different power outputs, resulting in varying power supplies to the lighting modules 230 on the shelves 200 at different vertical positions. This allows for targeted adjustment of the brightness and lighting effect of the lighting modules 230 on different shelves 200. Furthermore, by electrically connecting a single transmitting module 300 to the circuit board on the housing, the circuit structure is simplified compared to using multiple transmitting modules 300 each containing only one transmitting unit 301, facilitating the assembly of the transmitting module 300. Of course, in other embodiments, multiple transmitting modules 300 can be arranged at vertical intervals, with the spacing between two adjacent transmitting modules 300 adapted to the spacing between two adjacent sets of mounting holes 510 and balancing holes 520.

[0059] Referring to the above description regarding the multiple transmission units 301 provided in the transmission module 300, referring to... Figure 2 and Figure 3 In one embodiment, the transmitting module 300 includes multiple transmitting units 301, which are distributed vertically at intervals. The receiving module 400 selects one transmitting unit 301 adjacent to it. In this embodiment, the multiple transmitting units 301 allow different transmitting units 301 to achieve different power supply efficiencies with the receiving module 400. The structure of the bottom wall 132 for connecting the shelf 200 can be a hanging hole 510 or a balance hole 520 as in the above embodiment, or it can be a plug-in structure or a magnetic structure, etc. It only requires that the bottom wall 132 has multiple mounting positions distributed vertically at intervals. One shelf 200 is connected to one mounting position, and the distance between adjacent mounting positions is equal to the distance between adjacent transmitting units 301, so as to ensure that any shelf 200 or any position of the shelf 200 can be adjusted to make the lighting module 230 light up through the wireless power supply device.

[0060] In the case where the transmitting module 300 has multiple transmitting units 301, the multiple transmitting units 301 can be electrically connected in parallel or series according to the different power levels corresponding to the transmitting units 301. For example, in the series connection, one transmitting circuit board 310 is used, and multiple transmitting units 301 are connected in series sequentially. In the parallel connection, two or more transmitting circuit boards 310 are used, with at least one transmitting unit 301 on each transmitting circuit board 310, and the two or more transmitting circuit boards 310 are connected in parallel. In this embodiment, the transmitting module 300 has two transmitting circuit boards 310, and each transmitting circuit board 310 has two transmitting units 301. The input or output terminals of the two transmitting circuit boards 310 are connected in parallel. The parallel connection of the input or output terminals of the two transmitting circuit boards 310 is understood as: the input terminals of the two transmitting circuit boards 310 are connected in parallel, and the output terminals of the two transmitting circuit boards 310 are connected in parallel. The main path formed by the parallel connection is on one of the transmitting circuit boards 310, and then electrically connected to the second plug-in terminal (not shown in the figure) on the housing through the first plug-in terminal (not shown in the figure). In this way, the transmitter circuit board 310 with two transmitter units 301 can be formed into a module. By assembling multiple transmitter circuit boards 310 arranged in a modular manner, a transmitter module 300 with multiple transmitter units 301 can be formed, which reduces the design and production cost of the transmitter module 300.

[0061] Furthermore, in this embodiment, please refer to Figure 2 and Figure 3 The transmitting module 300 also includes a transmitting base 330 and a transmitting cover 320. The transmitting base 330 and the transmitting cover 320 are closed to form a receiving cavity for accommodating the transmitting circuit board 310. The transmitting base 330 is provided with a terminal hole 340 for exposing the first plug-in terminal of the transmitting module 300. The first plug-in terminal is located at the lower part of the transmitting module 300. The first plug-in terminal at the lower part of the transmitting module 300 is electrically connected to the second plug-in terminal in the refrigerator circuit structure by plugging in, realizing the electrical connection to the wireless power supply device. The terminal hole 340 exposed at the lower part of the transmitting base 330 can be tilted upward to avoid condensation water that may be generated in the receiving cavity by the refrigerator on the transmitting cover 320, thereby reducing the probability of short circuit damage to the transmitting unit 301. In addition, protective adhesive (not shown in the figure) can be filled into the receiving cavity to cover the transmitting unit 301, preventing condensation water droplets generated by the refrigerator from accumulating on the transmitting circuit board 310, thereby preventing short circuits and other adverse effects on the transmitting circuit board 310. The protective adhesive can be an insulating colloid such as epoxy resin adhesive, acrylic adhesive, or silicone polyurethane adhesive.

[0062] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 8The bottom wall 132 is provided with a hanging member 500 at a position adjacent to the two side walls 131, and / or, the bottom wall 132 is provided with a hanging member 500 at the middle position in the first direction and a hanging member 500 at a position adjacent to one side wall 131. The shelf 200 includes two hanging parts 240 distributed at intervals along the first direction, and the two hanging members 500 and the two hanging parts 240 are hung one-to-one. It is understandable that when the bottom wall 132 is provided with a hanging piece 500 near the two side walls 131, the two hanging parts 240 of the shelf 200, which are spaced apart in the first direction, are respectively provided near the two side walls 131. At this time, the shelf 200 fills or nearly fills the space of the inner liner 100 in the horizontal direction, which is a full-width shelf 200. When the bottom wall 132 is provided with a hanging piece 500 in the middle position in the first direction and a hanging piece 500 is provided near one side wall 131, one of the two hanging parts 240 of the shelf 200, which are spaced apart in the first direction, is provided near the side wall 131, and the other hanging part 240 is provided near the hanging piece 500 in the middle position. At this time, the shelf 200 half-fills or nearly half-fills the space of the inner liner 100 in the horizontal direction, which is a half-width shelf 200. Thus, for either half-width or full-width shelves 200, the receiving module 400 can wirelessly power the lighting module 230 via the transmitting module 300 on the side wall 131, thereby adapting to refrigerators of different widths. Furthermore, by utilizing the fixed relationship between the hanging part 240 and the hanging piece 500 in the first direction, the stability of any shelf 200 in the first direction can be maintained, thereby ensuring the lighting effect of the lighting module 230 on any shelf 200 and improving the flexibility of the wireless power supply device in this solution. Specifically, for the full-width shelf 200, both side walls 131 can be equipped with transmitting modules 300, and correspondingly, both sides of the full-width shelf 200 can be equipped with receiving modules 400 in the first direction. In this case, according to the horizontal width of the refrigerator liner 100, the lighting module 230 on the full-width shelf 200 can be equipped with two lighting units, which are electrically connected to the receiving modules 400 on both sides respectively; or, the transmitting module 300 can be equipped on one side wall 131, and the full-width shelf 200 is equipped with a receiving module 400 on one side in the first direction, so that the wireless power supply device is set on one side of the liner 100.

[0063] In one embodiment, please refer to Figure 7 and Figure 8The shelf 200 includes a partition 220 and a cantilever 210. The cantilever 210 is disposed on the side of the partition 220 distributed along a first direction and opposite to the side wall 131. The partition 220 is installed on the upper side of the cantilever 210. A receiving module 400, or a hanging part 240, or a receiving module 400 and a hanging part 240 are disposed on the cantilever 210. It should be noted that the cantilever 210 supports the partition 220. By placing the hanging part 240 on the cantilever 210, the weight of the items carried on the partition 220 can be transferred to the bottom wall 132 through a shorter path, thereby ensuring the stability of the shelf 200. The position where the hanging part 240 is located on the cantilever 210 can be thickened vertically to accommodate the hanging part 240 and the insertion protrusion 250, and to adapt to different stress positions of the cantilever 210, thereby improving the structural stability of the cantilever 210. The receiving module 400 is mounted on the cantilever 210. This arrangement utilizes the proximity of the cantilever 210 and the side wall 131 to ensure a smaller gap between the receiving module 400 and the transmitting module 300. Furthermore, it utilizes the space within the cantilever 210 to install the receiving module 400, reducing the space occupied by a separate mounting and thus lowering the structural complexity of the shelf 200. Alternatively, in other embodiments, a reinforcing strip can be provided on the side of the shelf 200 facing the bottom wall 132, with the hanging part 240 mounted on the reinforcing strip. Or, the receiving module 400 can be mounted on a partition 220.

[0064] In one embodiment, please refer to Figure 1 and Figure 2The inner wall 130 has a recessed mounting groove 110. The transmitting module 300 is installed in the mounting groove 110, and the receiving module 400 is positioned opposite the transmitting module 300 at the opening of the mounting groove 110. The transmitting module 300 is embedded in the mounting groove 110, avoiding direct exposure to the inner liner 100 and reducing the space occupied by the transmitting module 300 within the inner liner 100. This ensures efficient space utilization within the inner liner 100, allowing for the storage of more items and reducing the risk of damage to the transmitting module 300 during item access or shelf position adjustments. It also minimizes visual impact on the user, enhancing the simplicity and aesthetics of the inner liner 100. Simultaneously, the receiving module 400 is positioned directly opposite the transmitting module 300 at the opening of the mounting groove 110, forming the shortest and most perpendicular energy transmission path, avoiding electromagnetic loss or misalignment issues associated with traditional side or angled placement. The side wall 131 is positioned adjacent to the inlet 120, and the bottom wall 132 is positioned opposite the inlet 120. The transmitter module 300 is positioned on the side wall 131, thus avoiding direct contact between the wireless power supply device and the inlet 120, reducing the field of view occupied by the wireless power supply device, and improving the user's viewing experience. Furthermore, mounting the transmitter module 300 into the recessed mounting groove 110 in the inner wall 130 not only facilitates stable installation and improves stability, but also allows the transmitter module 300 to be closer to the housing, reducing the distance between the transmitter module 300 and the power connection structure on the housing. Of course, in other embodiments, the transmitter module 300 can also be directly mounted on the flat inner wall 130.

[0065] Furthermore, in this embodiment, please refer to Figures 1 to 3The transmitting module 300 is mounted in the mounting slot 110. The transmitting module 300 is provided with a first plug-in terminal, and the housing is provided with a second plug-in terminal. The first plug-in terminal is exposed outside the bottom of the mounting slot 110 and is electrically connected to the second plug-in terminal. It should be noted that the bottom of the mounting slot 110 is provided with a clearance opening (not shown in the figure), which allows the first plug-in terminal to be exposed outside the clearance opening for electrical connection with the second plug-in terminal. It can be seen that when the transmitter module 300 is snapped into the mounting slot 110 via a snap-fit ​​or sliding rail, the first plug-in terminal on the transmitter module 300 and the second plug-in terminal on the housing are simultaneously plugged in. Thus, the installation of the transmitter module 300 and the electrical connection between the transmitter module 300 and the power supply can be completed in a single installation step, simplifying the installation operation of the transmitter module 300. Alternatively, the transmitter module 300 can be first snapped into the mounting slot 110, and during the installation of the inner liner 100 into the housing, the first and second plug-in terminals are electrically plugged in, achieving simultaneous electrical connection of the transmitter module 300 and the power supply's electrical contact points during the installation of the inner liner 100, thereby simplifying the electrical connection operation between the transmitter module 300 and the power supply. Furthermore, the first and second plug-in terminals are plugged into each other at the bottom of the mounting slot 110, and the gap between the transmitter module 300 and the slot wall of the mounting slot 110 effectively isolates any condensation that may occur in the inner liner 100, thereby reducing the probability of poor contact caused by vibration, temperature changes, etc. Of course, in other embodiments, the transmitter module 300 can also be electrically connected to the power supply via terminal contact.
