Description

Technical Field

[0001] This application relates to the cross-technical field of home decoration and aromatherapy products, and in particular to biomimetic PU crafts with built-in aromatherapy devices. Background Technology

[0002] In the home decor and aromatherapy products sector, aromatherapy ornaments and PU simulation crafts are two common product categories, but both suffer from the drawback of limited functionality: On the one hand, ordinary aromatherapy ornaments are mostly simple columnar or bottle-shaped, lacking creativity and artistry in design, and can only achieve the function of fragrance emission, with insufficient decorative value, making it difficult to meet consumers' demand for aesthetic enhancement of their home environment; on the other hand, exquisite biomimetic PU crafts on the market (such as PU fruits, PU flowers, etc.), although becoming popular decorative items due to their highly realistic appearance and soft texture, only have a decorative function and cannot be supplemented with other practical functions, resulting in low added value and limited usage scenarios. Furthermore, existing aromatherapy carriers (such as aromatherapy stones and scented cotton pads) in aromatherapy ornaments are mostly fixedly connected to the ornament itself, requiring disassembly of the entire ornament for replacement, which is cumbersome. Meanwhile, PU simulated crafts, due to their mostly solid internal structure, cannot be functionally expanded and are difficult to adapt to aromatherapy components. To solve these problems, a product that combines high decorative appeal with practical aromatherapy functionality needs to be designed. This would integrate the aesthetic advantages of biomimetic PU crafts with aromatherapy functionality, while optimizing the ease of replacing aromatherapy components, thereby enhancing the product's practicality and added value. Therefore, a biomimetic PU craft with a built-in aromatherapy device is proposed. Utility Model Content

[0003] The purpose of this application is to provide biomimetic PU handicrafts with built-in aromatherapy devices, which solves the problem that ordinary aromatherapy ornaments have a single shape and PU handicrafts can only be used for decoration. This allows for the combination of decoration and aromatherapy functions, thereby increasing the added value of the product and expanding its usage scenarios. Moreover, the operation requires no tools, which solves the problem of cumbersome replacement of aromatherapy components and improves the convenience of taking out and putting away aromatherapy components.

[0004] The biomimetic PU craft with built-in aromatherapy device provided in this application adopts the following technical solution: it includes a biomimetic PU body and an aromatherapy component. The biomimetic PU body is a highly realistic fruit shape, and the biomimetic PU body is divided into a detachably connected upper body and a lower body along the axial direction. A hollow cavity is opened inside the biomimetic PU body, and the hollow cavity passes through the mating surface of the upper body and the lower body. The aromatherapy component is detachably installed in the hollow cavity. The aromatherapy component includes an aromatherapy evaporator holder and an aromatherapy evaporator body, and the aromatherapy evaporator body is inserted into the aromatherapy evaporator holder. Several microscopic vent holes are opened on the top or side of the upper body of the biomimetic PU body. The microscopic vent holes are connected to the hollow cavity, and the microscopic vent holes are distributed along the natural texture of the biomimetic PU body. By adopting the above technical solution, a biomimetic PU body with a highly realistic fruit shape, detachable upper and lower bodies, a hollow cavity, aromatherapy components, and microscopic ventilation holes are set up. During operation, the aromatherapy components can be inserted into the hollow cavity by separating the upper and lower bodies. The fragrance of the aromatherapy diffuser is evenly diffused through the microscopic ventilation holes, and the biomimetic PU body also serves a decorative function. This solves the problem of ordinary aromatherapy ornaments having a single shape and PU handicrafts being only decorative, and achieves a combination of decoration and aromatherapy functions, thereby increasing the added value of the product and expanding its usage scenarios.

[0005] Preferably, the upper body and the lower body are detachably connected by a threaded structure; the lower outer side of the upper body is provided with an internal thread, and the upper inner side of the lower body is provided with an external thread adapted to the internal thread, and the internal thread and the external thread are engaged.

[0006] By adopting the above technical solution, an internal thread is provided on the outer side of the lower end of the upper body and an external thread is provided on the inner side of the upper end of the lower body. During operation, the threads can be engaged or disengaged by rotating the upper or lower body, thus completing the assembly and disassembly of the body. No tools are required, simplifying the operation of taking out and putting in the aromatherapy components, solving the problem of cumbersome replacement of existing aromatherapy carriers, and improving the convenience of use.

[0007] Preferably, the upper body and the lower body can also be detachably connected by a hidden magnetic attraction structure; a first magnetic block is embedded at the lower end of the upper body, and a second magnetic block is embedded at the upper end of the lower body, which is magnetically attracted to the first magnetic block, and the magnetic poles of the first magnetic block and the second magnetic block are opposite.

[0008] By adopting the above technical solution, a first magnetic block is embedded at the lower end of the upper body and a second magnetic block is embedded at the upper end of the lower body; during operation, the upper body and the lower body can be fixed by magnetic attraction, and can be separated by applying external force; there are no obvious connection marks, maintaining the integrity of the appearance of the biomimetic PU body, while further simplifying the disassembly and assembly steps, and adapting to users with different operating habits.

[0009] Preferably, the aroma diffuser stick holder includes a fixing base and several fixing holes; the fixing base is a columnar structure adapted to the hollow cavity, and the outer side wall of the fixing base is in contact with the inner side wall of the hollow cavity; the fixing holes are evenly opened at the top of the fixing base, and the lower end of the aroma diffuser stick body is inserted into the fixing hole and is interference-fitted with the fixing hole.

[0010] By adopting the above technical solution, the aroma diffuser holder has a fixing seat and a fixing hole. During operation, the fixing seat fits into the hollow cavity, and the aroma diffuser body is inserted into the fixing hole with an interference fit. This prevents the aroma diffuser body from shaking inside the cavity, ensuring the stability of the aroma diffuser assembly. At the same time, the aroma diffuser body can be inserted and removed separately for replacement, improving replacement efficiency.

[0011] Preferably, the outer surface of the biomimetic PU body is coated with a wear-resistant and waterproof coating, which completely covers the outer surface of the biomimetic PU body without blocking the microscopic pores.

[0012] By adopting the above technical solution, a wear-resistant and waterproof coating is applied to the outer surface of the biomimetic PU body. During operation, the coating isolates the body from external wear and moisture, protecting its appearance. This prevents the PU body from being worn or deformed due to daily use or moisture, extending the product's lifespan. Furthermore, it does not block the microscopic pores and does not affect the aromatherapy function.

[0013] Preferably, a moisture-proof pad is also provided inside the hollow cavity; the moisture-proof pad is laid at the bottom of the hollow cavity of the lower body, the area of ​​the moisture-proof pad is the same as the cross-sectional area of ​​the bottom of the hollow cavity, and the lower end of the aroma diffuser stick holder is in contact with the moisture-proof pad.

[0014] By adopting the above technical solution, a moisture-proof pad is laid at the bottom of the hollow cavity. During operation, the moisture-proof pad absorbs the moisture in the cavity, and the lower end of the aromatherapy vaporizer holder is in contact with the moisture-proof pad. This prevents the aromatherapy vaporizer body from getting moldy due to moisture, ensuring the hygiene of the aromatherapy. At the same time, it buffers the collision between the holder and the lower body, reducing wear on the parts.

[0015] Preferably, the aroma diffuser body is made of porous ceramic or wood, and the length of the aroma diffuser body is less than the depth of the hollow cavity.

[0016] By adopting the above technical solution, the aromatherapy diffuser stick body is made of porous ceramic or wood material, and its length is less than the depth of the hollow cavity. During operation, the porous material can fully absorb and slowly evaporate the aromatherapy essential oil, prolonging the aromatherapy duration. The length-adaptive design avoids squeezing and damaging the aromatherapy diffuser stick body during assembly, ensuring safety in use.

[0017] Preferably, the outer wall of the fixing seat of the aroma diffuser stick is provided with a plurality of elastic protrusions; the elastic protrusions are evenly distributed along the circumference of the fixing seat, and the elastic protrusions elastically abut against the inner wall of the hollow cavity.

[0018] By adopting the above technical solution, an elastic protrusion is provided on the outer wall of the fixing seat; during operation, the elastic protrusion elastically abuts against the inner wall of the hollow cavity; the fit between the fixing seat and the cavity wall is enhanced, further preventing the aroma diffuser stick holder from shifting, and the elastic protrusion can be deformed during disassembly and assembly, without affecting the removal and placement of the holder, thus balancing stability and convenience.

[0019] In summary, this application includes at least one of the following beneficial technical effects: This biomimetic PU craft with a built-in aromatherapy device features a highly realistic fruit-shaped biomimetic PU body, detachable upper and lower bodies, a hollow cavity, aromatherapy components, and microscopic ventilation holes. In operation, the upper and lower bodies are separated, and the aromatherapy components are placed in the hollow cavity. The fragrance emitted by the aromatherapy diffuser overflows through the microscopic ventilation holes, while the biomimetic PU body also serves a decorative function. This addresses the limitations of ordinary aromatherapy ornaments with their monotonous designs and PU crafts that are merely decorative, combining decoration and aromatherapy functions to enhance product value and expand usage scenarios. The upper body has internal threads on its lower outer side, and the lower body has external threads on its upper inner side. During operation, rotating either the upper or lower body engages or disengages the internal and external threads, allowing for easy disassembly and assembly. Operation requires no tools, eliminating the cumbersome process of replacing aromatherapy components and improving the convenience of accessing and placing them. Attached Figure Description

The length-adaptive design prevents damage to the diffuser body 22 during assembly, ensuring safety. An elastic protrusion 213 is provided on the outer wall of the holder 211. During operation, the elastic protrusion 213 elastically abuts against the inner wall of the hollow cavity 13, enhancing the fit between the holder 211 and the cavity wall, further preventing displacement of the diffuser holder 21. The elastic protrusion 213 can deform during disassembly and assembly without affecting the placement and removal of the holder, balancing stability and convenience.

[0027] In this embodiment, a highly realistic fruit-shaped biomimetic PU body 1, a detachable upper body 11 and lower body 12, a hollow cavity 13, an aromatherapy component 2, and microscopic ventilation holes 14 are provided. During operation, the upper body 11 and lower body 12 are separated, and the aromatherapy component 2 is placed into the hollow cavity 13. The fragrance emitted by the aromatherapy diffuser body 22 overflows through the microscopic ventilation holes 14, while the biomimetic PU body 1 also serves a decorative function. This solves the problem of ordinary aromatherapy ornaments having a single shape and PU handicrafts only being decorative, achieving a combination of decoration and aromatherapy functions, increasing the added value of the product, and expanding the usage scenarios. By providing an internal thread 111 on the outer side of the lower end of the upper body 11 and an external thread 121 on the inner side of the upper end of the lower body 12, during operation, the upper body 11 or the lower body 12 is rotated to engage or disengage the internal thread 111 and the external thread 121, thus completing the disassembly and assembly of the body. The operation requires no tools, solving the problem of cumbersome replacement of the aromatherapy component 2 and improving the convenience of taking out and putting in the aromatherapy component 2.

[0028] The implementation principle of this application embodiment is as follows: First, the moisture-proof mat 3 is laid at the bottom of the hollow cavity 13 of the lower body 12; the aroma diffuser rod body 22 is taken and its lower end is inserted into the fixing hole 212 of the aroma diffuser rod holder 21, and the aroma diffuser component 2 is assembled by interference fit; then the aroma diffuser component 2 is placed into the hollow cavity 13 of the lower body 12, so that the lower end of the fixing seat 211 is in contact with the moisture-proof mat 3, and the elastic protrusion 213 on the outer side wall of the fixing seat 211 elastically abuts against the inner side wall of the hollow cavity 13, thus initially fixing the aroma diffuser component 2; If a threaded connection is used, align the inner thread 111 on the outer side of the lower end of the upper body 11 with the outer thread 121 on the inner side of the upper end of the lower body 12, and rotate the upper body 11 or the lower body 12 to make the threads fully engage, thus completing the body assembly; if a magnetic connection is used, align the first magnetic block 112 at the lower end of the upper body 11 with the second magnetic block 122 at the upper end of the lower body 12, and use magnetic attraction to fix the upper body 11 and the lower body 12 together; add aromatherapy essential oil to the aromatherapy diffuser body 22, which is made of porous material. After absorbing essential oils, the diffuser 22 begins to release its fragrance, completing the aromatherapy activation. The highly realistic fruit-shaped biomimetic PU body 1 can be used directly as a home decoration, serving a decorative purpose. The fragrance emitted from the diffuser 22 slowly diffuses through the microscopic vents 14 on the top or side of the upper body 11, achieving the aromatherapy function. The wear-resistant and waterproof coating 15 on the outer surface of the biomimetic PU body 1 isolates it from external wear and moisture, protecting its appearance without affecting fragrance release. When the aromatherapy scent fades and needs replacement, if it has a threaded connection, reverse the direction... Rotate the upper body 11 and the lower body 12 to separate the internal thread 111 from the external thread 121; if it is a magnetic connection, apply external force to separate the upper body 11 and the lower body 12; take out the aromatherapy component 2 from the hollow cavity 13, pull out the old aromatherapy vaporizer body 22, replace it with a new aromatherapy vaporizer body 22 and add essential oil, put the aromatherapy component 2 back into the hollow cavity 13, and then reassemble the upper body 11 and the lower body 12; if the hollow cavity 13 is too humid, the moisture-proof pad 3 can be replaced to ensure that the aromatherapy component 2 is dry before use.
