[0030] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0031] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0034] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0035] According to one embodiment of the present application, an adapter is provided. The adapter includes an adapter unit 1 and a connecting unit 2. The adapter unit 1 includes an adapter portion 11, wherein the adapter portion 11 has a connecting cavity 111 therein, and the adapter portion 11 is provided with connecting ports 112 in different orientations, wherein a plurality of connecting ports 112 are connected to the connecting cavity 111. The connecting unit 2 includes a connecting portion 21, wherein the connecting portion 21 has a flow cavity 211, and the connecting portion 21 is detachably connected to the optional connecting port 112. When the connecting portion 21 is connected to the connecting port 112, the flow cavity 211 is connected to the connecting cavity 111. The connecting portion 21 has opposite ends connected to the connecting port 112 and a drying rod 3, respectively. When the adapter portion 11, the connecting portion 21, and the drying rod 3 are connected, the connecting cavity 111, the flow cavity 211, and the drying rod 3 remain connected.

[0036] like Figures 1 to 5 As shown, the adapter 11 is in the shape of a rectangular block. A connecting cavity 111 is provided within the rectangular block. The cavity can be rectangular, spherical, or other shapes. A connecting port 112 is provided on each end face of the rectangular block, allowing the connecting cavity 111 to communicate with the outside through the connecting port 112, facilitating the passage of a heating medium or heating wire or other medium or component through the adapter.

[0037] Of course, in the embodiment of the present application, the adapter portion 11 is not limited to the above structure, and those skilled in the art can configure it according to actual needs. For example, the adapter portion 11 can also be spherical, cylindrical, etc.

[0038] The connecting unit 2 includes a connecting portion 21, which is tubular, and the opposite ends of the connecting portion 21 can be detachably connected to the adapter 112 and the drying rod 3 respectively, and the detachable connection can be achieved by snap connection, interference fit or threaded connection.

[0039] By opening a plurality of adapter ports 112 with different directions in the adapter portion 11 and connecting the connecting portion 21 to the adapter ports 112, the plurality of adapter ports 112 are interconnected through the connecting cavity 111, so that a suitable adapter port 112 can be selected according to actual usage, so that the heating medium or element changes the flow direction or extension direction along the connecting channel to perform operations such as heating a plurality of drying rods.

[0040] For example, Figure 5 As shown, when the device connected to the adapter needs to be placed in a corner, a connecting portion 21 can be set at the adapter interface 112 adjacent to the adapter portion 11. The adapter portion 11 is used to give the device a bending structure, which can adapt to the position requirements of different scenes such as corners, thereby effectively improving the adaptability of the device.

[0041] The flow cavity 211 of the connecting portion 21 is in communication with the communication cavity 111 of the adapter portion 11. The connecting portion 21 connects the adapter portion 11 to the drying rod 3 to be connected, thereby guiding the heating medium used to heat the drying rod 3, or guiding the heating wire to bend and protecting the bent portion of the heating wire.

[0042] Of course, in the embodiment of the present application, the functions of the materials in the circulation cavity 211 and the communication cavity 111 are not limited. They can be heating media, heating wires, cooling media, etc. Those skilled in the art can set them according to actual needs.

[0043] The adapter portion 11 and the connecting portion 21 can be made of materials such as metal or plastic.

[0044] The adapter part 11 is provided with a plurality of adapter interfaces 112 facing different directions. By selecting the adapter interfaces 112 facing different directions and connecting them to one end of the connecting part 21, and setting the end of the drying rod on the other end of the connecting part 21, drying racks of different shapes can be assembled to adapt to different scene requirements.

[0045] The shape of the adapter is related to the position and number of the adapter interfaces selected for the connection part.

[0046] The adapter ports 112 with different orientations are selected and connected to the connecting part 21, so that the flow cavities 111 of multiple adapter parts 21 are respectively connected to the connecting cavity 111, so that the heating medium or heating wire and other media or elements can flow into the flow cavity to change direction when passing through the connecting cavity 111 in the adapter part 11, so that the heating medium or element can perform heating, drying, sterilization and other operations on drying racks of different shapes.

[0047] In an embodiment of the present application, a plurality of adapter ports 112 are provided on the adapter portion 11 and connected to the connecting cavity 111, so that the connecting portion 21 can be installed on the corresponding adapter port 112 according to the requirements of different scenarios, so that various shapes can be changed according to space requirements during the assembly process, thereby improving the adaptability of the equipment to be assembled. Moreover, the adapter portion 11 and the connecting portion 21 are detachably connected, so that the volume of the equipment to be assembled can be reduced during operations such as transportation, which not only facilitates packaging and transportation and reduces packaging and transportation costs, but also facilitates the replacement of local parts of the equipment to be assembled, effectively reducing maintenance and replacement costs.

[0048] In one example, the adapter portion 11 has at least two end faces, each of which is provided with an adapter port 112. At least two of the adapter ports 112 are connected to the connecting portion 21, and a blocking piece 113 is provided in the other adapter ports 112. The blocking piece 113 is detachably connected to the adapter port 112.

[0049] like Figures 1 to 5 As shown, the adapter portion 11 is rectangular. It has six end faces, each with a circular adapter port 112. Each adapter port 112 communicates with a communication cavity 111 within the rectangular block. This allows the connection portion 21 connected to the adapter port 112 to communicate with the communication cavity 111, allowing the heating medium or heating wire to pass through the communication cavity 111 and enter the flow cavity 211 of the connection portion 21.

[0050] For example, Figure 6 As shown, the adapter is assembled into a drying rack. The adapter port 112 of the adapter portion 11 is connected to the connecting portion 21, and the ends of the drying rods 3 are sleeved on the connecting portion 21, so that multiple drying rods 3 are connected through the adapter portion 11 and the connecting portion 21, so as to facilitate operations such as heating the drying rods 3. In addition, the detachable connection between the adapter portions 11 and the adapter portions 11 allows for various shapes to be changed according to space requirements during the assembly process, which has strong applicability.

[0051] In the embodiment of the present application, the outer wall of the blocking member 113 has an external thread, which matches the internal thread of the inner wall of the adapter 112. The blocking member 113 and the adapter 112 are detachably connected by a threaded seal. By detachably setting the blocking member 113 in the adapter 112, it is convenient to adjust the direction of passage of the heating medium or the heating wire. When the blocking member 113 is embedded in the adapter 112, the adapter 112 of the adapter 11 is in a closed state. When the blocking member 113 is detached from the adapter 112, the connection portion 21 is connected to the adapter 112, thereby achieving conduction between the adapter 11 and the connection portion 21.

[0052] In one example, the adapter part 11 has a limiting groove 114 extending along the radial direction of the adapter interface 112, and the connecting part 21 has a limiting protrusion 115 adapted to the limiting groove 114. When the connecting part 21 is connected to the adapter interface 112, the limiting protrusion 115 forms a limiting fit with the limiting groove 114; and / or, the adapter interface 112 is provided with a cover plate 12, and the cover plate 12 is detachably connected to the adapter interface 112.

[0053] like Figures 1 to 5 As shown, the adapter portion 11 is in a rectangular block shape and has six end faces. Each end face is provided with a circular adapter port 112 , and the adapter port 112 is used to connect to the connecting portion 21 .

[0054] A plurality of limiting grooves 114 are formed on each end surface of the adapter portion 11 . The limiting grooves 114 are arranged along the circumferential direction of the adapter port 112 and are in communication with the adapter port 112 .

[0055] The end of the connecting portion 21 connected to the adapter 112 has a limiting protrusion 115 arranged along the circumferential direction, and the limiting protrusion 115 is adapted to the limiting groove 114. When the connecting portion 21 is connected to the adapter 112, the limiting protrusion 115 is embedded in the limiting groove 114, and a limiting fit is formed by the limiting protrusion 115 and the limiting groove 114 to limit the position of the connecting portion 21 and the adapter 112 in the circumferential direction, thereby improving the connection stability between the connecting portion 21 and the adapter 11.

[0056] Of course, in the embodiment of the present application, the adapter portion 11 is not limited to the above structure, and those skilled in the art can configure it according to actual needs. For example, the adapter portion 11 can also be spherical.

[0057] like Figures 1 to 5As shown, the adapter portion 11 is rectangular, and the adapter port 112 is a circular opening formed on the end surface of the adapter portion 11. The adapter port 112 communicates with the communication cavity 111 within the adapter portion 11. The inner wall of the adapter port 112 is provided with an internal thread. When the adapter port 112 is not connected to the connecting portion 21, a sealing member 113 can be threadedly connected to the adapter port 112 to seal the adapter port 112 and adjust the delivery direction of the heating medium or heating wire.

[0058] A cover plate 12 can be provided at the adapter port 112 where the blocking member 113 is provided, and patterns, logos, etc. can be printed on the cover plate 12. Providing the cover plate 12 not only reduces the difficulty of cleaning, prevents dust, liquids and other impurities from accumulating there, but also improves the aesthetics of the adapter.

[0059] The cover plate 12 is in the shape of a circular plate, and a plurality of limiting protrusions 115 are provided along the outer circumference of the cover plate 12 . The number and size of the limiting protrusions 115 are adapted to the number and size of the limiting grooves 114 , which can improve the connection strength between the cover plate 12 and the adapter 11 .

[0060] In one example, the connecting unit 2 includes a first sealing portion 22 , which is sleeved on the connecting portion 21 , and the first sealing portion 22 and the connecting portion 21 are detachably connected.

[0061] like Figures 1 to 5 As shown, the connecting unit 2 further includes a first sealing portion 22. The first sealing portion 22 is made of plastic or other materials and is tubular and sleeved on the outside of the metal connecting portion 21. The inner diameter of the first sealing portion 22 matches the outer diameter of the connecting portion 21.

[0062] By detachably connecting the connecting portion 21 and the first sealing portion 22, the first sealing portions 22 of different outer diameters can be replaced, and the first sealing portions 22 of different outer diameters can be selected according to the drying rods 3 of different inner diameters, so that the connecting portion 21 can be adapted to the drying rods 3 of different diameters through the first sealing portion 22, thereby effectively improving the adaptability of the connecting portion 21 and improving the connection strength between the connecting portion 21 and the drying rod 3.

[0063] In one example, the connecting unit 2 further includes a second sealing portion 24 and a third sealing portion 25; the second sealing portion 24 is arranged between the connecting portion 21 and the first sealing portion 22; the third sealing portion 25 is sleeved on the connecting portion 21, and when the connecting portion 21 is connected to the drying rod 3, the third sealing portion 25 abuts between the connecting portion 21 and the drying rod 3; wherein, the side of the third sealing portion 25 facing away from the connecting portion 21 has a plurality of recessed portions 251 opened in the axial direction.

[0064] like Figures 1 to 5 As shown, a second sealing portion 24 is provided between the connecting portion 21 and the first sealing portion 22. The second sealing portion 24 is a sealing ring. By providing the sealing ring, the sealing effect between the first sealing portion 22 and the connecting portion 21 can be enhanced to prevent the heating medium and the like from flowing through the gap between the first sealing portion 22 and the connecting portion 21 during the use of the adapter, resulting in liquid leakage and the like.

[0065] like Figures 1 to 5 As shown, the third sealing portion 25 is a square sleeve, which can be made of materials such as rubber and silicone. Multiple recessed portions 251 are formed on the side of the third sealing portion 25 that contacts the drying rod 3. These recessed portions 251 are arranged layer by layer along the axial direction. This multi-layer arrangement of recessed portions 251 not only effectively increases the ease with which liquids, such as a heating medium, can flow through the gap between the third sealing portion 25 and the drying rod 3, thereby strengthening the seal between the third sealing portion 25 and the drying rod 3, but also reduces the contact area between the third sealing portion 25 and the inner wall of the drying rod 3, effectively simplifying the assembly of the third sealing portion 25 and the drying rod 3.

[0066] The third sealing portion 25 is sleeved on the outside of the first sealing portion 22. By setting the third sealing portion 25 on the outside of the first sealing portion 22, it can not only tighten the first sealing portion 22 to enhance the connection strength between the first sealing portion 22 and the connecting portion 21, but also can achieve interference fit with the drying rod 3 through the protrusion adjacent to the recessed portion 251. The inner wall of the drying rod 3 and the protrusion of the third sealing portion 25 are abutted against each other, thereby increasing the friction between the third sealing portion 25 and the inner wall of the drying rod 3, thereby effectively enhancing the connection strength between the drying rod 3 and the adapter.

[0067] In one example, the connecting unit 2 further includes a fastener 23 , one end of which passes through the first sealing portion 22 along a radial direction of the first sealing portion 22 and is detachably connected to the connecting portion 21 .

[0068] like Figures 1 to 5 As shown, the connecting unit 2 further includes a fastener 23, which is a bolt. The end of the bolt passes through one side of the first sealing portion 22 along the radial direction of the first sealing portion 22 and is connected to the side wall of the connecting portion 21, so that the bolt fixes the first sealing portion 22 to the connecting portion 21.

[0069] The bolts fix the first sealing part 22 to the connecting part 21, which can limit the axial direction of the first sealing part 22 in the connecting part 21 and prevent the first sealing part 22 from moving along the axial direction of the connecting part 21, causing the first sealing part 22 to fall off the connecting part 21, and then causing the drying rod 3 to be separated from the connecting part 21, affecting the connection strength between the connecting part 21 and the drying rod 3.

[0070] The bolts fix the first sealing part 22 to the connecting part 21, which can limit the circumferential position of the first sealing part 22 in the connecting part 21 and prevent the first sealing part 22 from rotating around the axis of the connecting part 21, affecting the connection stability between the drying rod 3 and the adapter.

[0071] According to another embodiment of the present application, a drying rack is provided. The drying rack includes a plurality of drying rods 3 and the adapter as described above, wherein the drying rods 3 are detachably connected to the adapter.

[0072] like Figures 1 to 6 As shown, the adapter is suitable for a drying rack. The drying rack includes multiple drying rods 3 and multiple adapters. The multiple drying rods 3 are connected via the adapter. By providing multiple adapter ports 112 on the adapter portion 11, and by providing detachable connectors between the adapter portion 11, the connecting portion 21, and the drying rods 3, the drying rods 3 can be connected to corresponding adapter ports 112 according to space requirements. This allows the drying rack to be transformed into various shapes to suit different scenarios.

[0073] In one example, the drying rod 3 is tubular, the adapter 11 is embedded in the drying rod 3 , and the drying rod 3 is communicated with the circulation cavity 211 and the communication cavity 111 .

[0074] like Figures 1 to 6 As shown, the drying rod 3 can be hollow cylindrical or square. An adapter is connected to each end of the drying rod 3. Another drying rod 3 is connected to the other connecting portion 21 of the adapter, allowing the desired drying rack shape to be assembled based on space requirements. The drying rod 3 is connected to the other drying rod 3 via the adapter. Heating wires and other components can be installed within the drying rack to heat the rack and sterilize towels.

[0075] The shape of the drying rack is related to the position and number of the connecting parts set on the adapter part. The connecting part 21 is equipped with adapters of different numbers and directions to form adapters of different shapes. The drying racks of different shapes can be assembled by connecting the drying rods and the adapters.

[0076] In one example, the drying rack further includes a leg 4 , one end of which is provided with a support platform 41 , and the end of the leg 4 facing away from the support platform 41 is embedded in the adapter 112 , and the leg 4 is detachably connected to the adapter 11 .

[0077] like Figures 1 to 6As shown, the leg 4 is rod-shaped, and one end of the leg 4 has an external thread. The external thread of the leg 4 is compatible with the internal thread of the adapter 112. The leg 4 and the adapter 112 are fixed by a threaded connection, so that the support platform 41 can support the drying rack, so that a certain space is suspended between the drying rack and the wall, so that towels, clothes, etc. can be placed, and towels, clothes, etc. can be prevented from sticking to the wall and getting wet.

[0078] The supporting legs 4 are detachably connected to the adapter portion 11, so that the position of the supporting legs 4 on the drying rack is adjustable, so that adjustments can be made according to actual needs, thereby improving the adaptability of the drying rack.

[0079] In one example, the drying rack also includes a water inlet pipe 5 and a water outlet pipe 6, the water outlet pipe 6 is connected to the adapter port 112 of one of the adapter parts 11, and the water outlet pipe 6 is connected to the connecting cavity 111, the water inlet pipe 5 is connected to the adapter port 112 of another adapter part 11, and the water outlet pipe 6 is connected to the connecting cavity 111, and the water outlet pipe 6 is connected to the water inlet pipe 5.

[0080] like Figures 1 to 6 As shown, the drying rack is connected to a water outlet pipe 6 and a water inlet pipe 5. The water outlet pipe 6, the adapter, the drying rod 3 and the water inlet pipe 5 are connected so that the heating medium can flow in the drying rack, so that the drying rack can be heated evenly, which speeds up the drying and sterilization efficiency.

[0081] Of course, the present invention is not limited to the above drying method, and those skilled in the art can configure it according to actual needs. For example, the outlet pipe 6, the adapter, the drying rod 3 and the water inlet pipe 5 are connected so that the heating wire can be laid in the drying rack.

[0082] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
