Such toys have the characteristics of realistic and cute shapes, soft touch, not afraid of extrusion, convenient cleaning, strong decorative properties, high safety and a wide range of applicable populations;

[0003] In the prior art, specific spices or fragrances are usually added inside plush toys so that the plush toys can emit scents when in use. The spices or fragrances are in powder or solid form. After the powder materials are in contact with air for a long time, they may agglomerate due to the humid use environment, and moisture or stains may also adhere to the surface of the solid materials, thereby affecting the scent emission effect. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the present invention provides a scented plush toy and a manufacturing method thereof to solve the above technical problems that the spices or fragrances are in powder or solid form, and after the powder materials are in contact with air for a long time, they may agglomerate due to the humid use environment, and moisture or stains may also adhere to the surface of the solid materials, thereby affecting the scent emission effect.

[0006] (2) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solutions: A scented plush toy, comprising: a plush outer shape part and a scent volatilization mechanism. The scent volatilization mechanism is assembled inside the plush outer shape part. The scent volatilization mechanism includes a first return airbag, a second return airbag and a spice box, and the first return airbag, the second return airbag and the spice box are connected through a hose. A box cover is installed outside the spice box, and the box cover is connected to the spice box through a hinge and a buckle to achieve the sealing and opening of the spice box, facilitating the replacement of the internal spice materials. The box cover is exposed on the outer surface of the plush outer shape part. A whistle mechanism is inserted through the middle of the box cover. The inner cavity of the whistle mechanism is communicated with the inner cavity of the spice box, and a diversion block is provided in the cavity of the whistle mechanism. Sound holes are opened on the outside of the whistle mechanism. A sealing cover is screwed on the outer side of the inner cavity of the whistle mechanism.

[0008] Preferably, the spice box is connected to the first return airbag, the number of second return airbags is four, and they are all connected to the first return airbag, and the second return airbags are assembled at the four inner corners of the plush shape part. The design of the second return airbag and the first return airbag allows the four corners and the middle of the plush shape part to generate gas when squeezed.

[0009] Preferably, the plush appearance part includes a plush leather layer and a soft colloid, the interior of the soft colloid is filled with textiles, the plush leather layer outside the plush appearance part is arranged on the outside of the soft colloid through a zipper, and the plush leather layer can be disassembled and cleaned, thereby keeping the plush appearance part clean and tidy.

[0010] Preferably, the backs of the first return airbag and the second return airbag are both equipped with connecting blocks, and the connecting blocks are connected to the plush shape part. The connecting blocks can fix the second return airbag inside the plush shape part. The connecting blocks can be hidden buckles or Velcro stickers, etc.

[0011] Preferably, the bottom of the first return airbag is connected to a one-way air intake valve tube, which is a one-way tube valve commonly seen in the prior art. The one-way air intake valve tube can only intake air in one direction but cannot exhaust air. It cooperates with the square plate, the sealing baffle and the return spring to prevent the spice box from sucking external airflow into the interior of the first return airbag through the whistle mechanism, thereby avoiding affecting the diffusion of the fragrance and then sucking it in again after it is discharged.

[0012] Preferably, a square plate is movably placed inside the spice box, and a flow channel is left between the square plate and the inner wall of the spice box, and obliquely arranged sealing baffles are installed on the upper and lower sides of the air inlet of the spice box, a reset spring is connected between the square plate and the spice box, and a crushing arm is connected to the outside of the square plate, and spices are placed in the external space of the crushing arm. The square plate cooperates with the sealing baffle and the reset spring to form a simple one-way valve, so that the spice box can only exhaust air in one direction but cannot take in air, thereby avoiding gas backflow. At the same time, the crushing arm can squeeze, drive and crush the spices inside the spice box, thereby improving the fragrance diffusion effect of the spices.

[0013] Preferably, a vibration block is installed on the top of the spice box, and a spring vibration switch and a power supply module are installed on the back of the first return airbag. The spring vibration switch, the power supply module and the vibration block are all connected by wires, and a delay circuit is provided inside the spring vibration switch. When the user picks up or shakes the plush toy, the spring vibration switch is triggered to vibrate, causing it to start and drive the vibration block with an eccentric design to vibrate. This vibration is then transmitted to the spice box, causing the spices in the box to emit fragrance more effectively due to the vibration. In addition, this mechanism also assists the timely fall of the spice block on the crushing arm and enters the circulation path, thereby enhancing the effect of fragrance dissemination.

[0014] It also includes a manufacturing method for a plush toy, which is applied to the scented plush toy described above. The manufacturing method includes the following steps:

[0015] S1 Prepare materials:

[0016] Select high-quality plush fabric as the main material for the plush outer shape part, and at the same time prepare all components for manufacturing the scent volatilization mechanism, including a first return airbag, a second return airbag, a spice box, a hose, a one-way intake valve pipe, a square plate, a crushing arm, a return spring, a sealing baffle, a box cover, a whistle mechanism and its internal flow guide block, sound holes, a sealing cover, a connecting block, a vibration block, a spring vibration switch and a power supply module.

[0017] S2 Assemble the scent volatilization mechanism:

[0018] First, connect the first return airbag and the second return airbag through a hose to ensure that gas can flow freely between the airbags. Then, install the spice box in place and connect it to the first return airbag through a hose, and the connection ends of the hose are all processed into corrugated telescopic structures. Place a square plate inside the spice box and ensure that there is enough flow channel between the square plate and the inner wall of the spice box. Install the sealing baffle and the return spring to ensure that the square plate can move normally. Connect the crushing arm to the outside of the square plate and place an appropriate amount of spices in the external space of the crushing arm.

[0019] S3 Install the whistle mechanism:

[0020] Insert the whistle mechanism into the middle of the box cover and ensure that the inner cavity of the whistle mechanism is connected to the inner cavity of the spice box. Install a flow guide block in the cavity of the whistle mechanism and adjust its position to ensure smooth gas flow. Open sound holes at the top of the inner cavity of the whistle mechanism and install a sealing cover by screwing.

[0021] S4 Connect the airbag to the plush outer shape part:

[0022] Install connecting blocks on the back of the first return airbag and the second return airbag, and fix the airbags to the inside of the plush outer shape part through these connecting blocks. Ensure that the airbags are evenly distributed around the plush toy so that uniform gas flow can be generated when squeezed.

[0023] S5 Install the vibration mechanism and the power supply module:

[0024] Install a vibration block on the top of the spice box, and install a spring vibration switch and a power supply module on the back of the first return airbag. First, wind the wire in a spiral, and then connect the spring vibration switch, the power supply module and the vibration block through the wire to ensure that when the spring vibration switch is triggered, it can drive the vibration block to vibrate. At the same time, set a delay circuit inside the spring vibration switch to control the duration and frequency of the vibration.

[0025] S6 Sew the plush exterior and stuff with materials:

[0026] Cut the plush fabric according to the design pattern and sew it into the shape of the plush toy. During the sewing process, ensure that all components are properly fixed. Finally, stuff the plush toy with an appropriate amount of stuffing material to give it a soft feel and a good appearance, obtaining a completed and shaped plush toy.

[0027] S7 Test and debug:

[0028] Conduct functional and performance tests on the completed plush toy to test whether the fragrance volatilization mechanism, vibration mechanism, and whistle mechanism can work properly. If problems or defects are found, promptly debug and repair them to ensure that the fragrance volatilization mechanism can work properly and the vibration mechanism and whistle mechanism can respond to corresponding actions.

[0029] Preferably, in the step S2 of assembling the fragrance volatilization mechanism, the pipe body parts of the hose connected to the first return airbag, the second return airbag, and the spice box all undergo a rolling forming operation to form a telescopic corrugated pipe structure, also avoiding the influence of pipe body pulling on the connection between the vibration mechanism and the spring vibration switch, preventing the spring vibration switch from being accidentally touched, and further avoiding the influence of the vibration mechanism on the spring vibration switch during vibration.

[0030] Preferably, in the step S3 of installing the whistle mechanism, a sealing gasket layer is also installed outside the plug-in part of the whistle mechanism, and there are no less than three groups of whistle mechanisms, and the aperture of the sound emitting holes and the shape of the internal flow guiding blocks of each group of whistle mechanisms are all different, facilitating the replacement of different whistle mechanism components according to usage requirements so that the toy can emit whistles with different tones or timbres.

[0031] Preferably, in the step S5 of installing the vibration mechanism and the power supply module, the wire is installed in a way that closely adheres to the surface of the hose connecting the spice box and the first return airbag, and the wire is in a spiral spring shape, enabling the wire to have elastic contraction and extension properties, avoiding the influence of wire pulling on the connection between the vibration mechanism and the spring vibration switch, and further reducing the influence of the vibration mechanism on the spring vibration switch during vibration.

[0032] Preferably, in the step S5, the vibration mechanism and the power supply module are installed, and the delay circuit includes a triode as a switch tube and a charge and discharge capacitor, the triode is connected to the spring electrode assembly of the spring vibration switch, the capacitor is connected to the triode, and the outside of the capacitor is also connected to a field effect tube. The spring vibration delay switch contains a spring electrode inside. When the external vibration is triggered, the electrode will generate a signal, and this signal will trigger the triode to turn on, and then charge a capacitor. The voltage formed by the capacitor will maintain a field effect tube to turn on, so that the vibration block works. When the vibration stops, the capacitor will gradually discharge. When the discharge is completed, the field effect tube enters a cut-off state, and the vibration block stops working, thereby achieving a delay effect.

[0033] (III) Beneficial effects

[0034] Compared with the prior art, the present invention provides a scented plush toy and a manufacturing method thereof, which has the following beneficial effects:

[0035] The scented plush toy can generate airflow by pressing the airbag and drive the spices in the spice box to emit fragrance outwards. A movable square plate is added inside the spice box, which cooperates with the elastic reset structure and the sealing baffle to achieve the effect of a simple one-way check valve to prevent airflow backflow. At the same time, when the square plate is moved by the impact of the airflow, it will drive the movement of the external breaking arm, so as to impact and break the spices placed inside the box body, and turn out the internal effective ingredients of the agglomerated powder spices or the solid spices stained due to surface moisture, so as to improve the fragrance diffusion effect. The added whistle mechanism is connected to the spice box, and can generate airflow in the spice box by pressing the airbag to make a whistle sound, thereby improving the fun of the toy.

[0036] When the scented plush toy of the present invention is manufactured, the connection parts between the hose and the airbag and the fragrance box are processed to form a telescopic bellows structure, thereby improving the firmness and flexibility of the connection. At the same time, the structure cooperates with the wire in a spiral telescopic structure to avoid the connection between the vibration mechanism and the spring vibration switch being affected by the pulling of the wire or the pipe, thereby reducing the influence of the vibration mechanism on the spring vibration switch during vibration.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The present invention provides a technical solution, please refer to Figure 1 and Figure 2 A scented plush toy comprises a plush outer shape part 1, wherein a scent volatilization mechanism 2 is arranged inside the plush outer shape part 1.

[0044] The fragrance volatilization mechanism 2 includes a first return airbag 21, a second return airbag 22 and a spice box 23, and the first return airbag 21, the second return airbag 22 and the spice box 23 are connected by a hose 24. A box cover 27 is installed on the outside of the spice box 23, and the box cover 27 is exposed on the outer surface of the plush appearance part 1. A whistle mechanism 28 is inserted through the middle of the box cover 27. The whistle mechanism 28 is square as a whole and has a cavity inside. The cavity is connected to the inner cavity of the box cover 27. A guide block 281 is provided in the cavity of the whistle mechanism 28, and a sound hole 283 is provided on the outside of the whistle mechanism 28.

[0045] A sealing cap 282 is screwed onto the outer side of the inner cavity of the whistle mechanism 28. Gas is generated when the first return airbag 21 and the second return airbag 22 are squeezed. Memory foam and a return spring are also installed inside the second return airbag 22 and the first return airbag 21, so as to improve the return performance of the second return airbag 22 and the first return airbag 21. The interior of the spice box 23 can be filled with spices, and the box cover 27 can seal the spice box 23 to facilitate the replacement of the spices inside the spice box 23.

[0046] The inner cavity of the whistle mechanism 28 communicates with the inner cavity of the spice box 23. The whistle mechanism 28 and the diversion block 281 cooperate to enable the fragrance air flow entering the inside of the whistle mechanism 28 to be discharged through the sound generating holes 283, thereby generating a whistle. The added cover 282 is a threaded detachable structure. Removing the cover 282 can expose the inner cavity of the whistle mechanism 28, and the air flow can be discharged normally without passing through the sound generating holes 283, thereby avoiding the generation of a whistle. The setting of whether to generate a whistle can be adjusted according to actual needs. The design is reasonable and highly practical.

[0047] Please refer to Figure 3 and Figure 4 , the second return airbag 22 is assembled at the four corners inside the plush outer part 1, and the first return airbag 21 is assembled at the central abdomen of the plush outer part 1. The design of the second return airbag 22 and the first return airbag 21 enables the four corners and the middle part of the plush outer part 1 to discharge gas when being squeezed, improving the odor diffusion effect of the spice.

[0048] The plush skin layer outside the plush outer part 1 is sleeved outside the soft colloid through a zipper. The plush skin layer can be disassembled and cleaned, thereby keeping the plush outer part 1 clean. The plush outer part 1 includes a plush skin layer and a soft colloid, and the inside of the soft colloid is filled with textiles such as cotton wadding and velvet.

[0049] Connection blocks 26 are assembled on the back surfaces of both the first return airbag 21 and the second return airbag 22, and the connection blocks 26 are connected to the plush outer part 1. The connection blocks 26 can be snap fasteners or magic tape, etc., for firmly connecting the second return airbag 22 to the plush outer part 1. A one-way intake valve tube 25 is connected to the bottom of the first return airbag 21. The one-way intake valve tube 25 is a common one-way tube valve in the prior art. The one-way intake valve tube 25 can only intake air unidirectionally and cannot exhaust air. Cooperating with the square plate 29, the sealing baffle 291 and the return spring 293 can prevent the spice box 23 from sucking the external air flow into the inside of the first return airbag 21 through the whistle mechanism 28, thereby avoiding being sucked in again after the fragrance diffuses and is discharged, and reducing the fragrance diffusion effect.

[0050] Inside the spice box 23, a square board 29 is placed movably, and an overflow channel is provided between the square board 29 and the inner wall of the spice box 23. On both lower sides inside the upper air inlet of the spice box 23, inclined sealing baffles 291 are installed. In the initial state, under the pressing action of the return spring 293, the sealing baffles 291 are in close contact with the square board 29, so that the air inlet between the sealing baffles 291 can be closed. A return spring 293 is connected between the square board 29 and the spice box 23. A crushing arm 292 is connected to the outside of the square board 29. Spices are placed in the outer space of the crushing arm 292. Blades can be provided outside the crushing arm 292 to divide the spices, avoiding the spices from agglomerating. The square board 29 cooperates with the sealing baffle 291 and the return spring 293 to form a simple one-way valve, enabling the spice box 23 to only exhaust air unidirectionally and not intake air. At the same time, the crushing arm 292 can squeeze, drive, and crush the spices inside the spice box 23, improving the fragrance diffusion effect of the spices.

[0051] A vibration block 3 is installed on the top of the spice box 23. The vibration block 3 has a structure similar to that of a mobile phone vibration motor and will undergo eccentric vibration after being turned on and off. A spring vibration switch 4 and a power supply module 5 are installed on the back of the first return airbag 21. The spring vibration switch 4, the power supply module 5, and the vibration block 3 are all connected by wires. A delay circuit is provided inside the spring vibration switch 4. When the user picks up or shakes the plush toy, it will drive the vibration of the spring vibration switch 4, that is, turn on the spring vibration switch 4, drive the vibration block 3 with an eccentric structure to start vibrating, thereby driving the vibration of the spice box 23, enabling the spices in the box to better release the fragrance due to the vibration, and at the same time also helping the spice blocks adhering to the crushing arm 292 to fall into the overflow channel in due course, further improving the fragrance diffusion effect. And due to the addition of the delay circuit, after a period of time, the vibration will naturally stop, that is, it avoids wasting electricity and prolongs the working life of the electronic components. The wire part of the vibration assembly is closely attached to the outside of the hose 24, making the wiring beautiful and also avoiding the wire from being broken due to accidental touch. At the same time, the vibration assembly and the spring switch assembly are installed separately. The end of the hose 24 connecting the spice box 23 and the first return airbag 21 is of a corrugated structure, with elasticity and having a certain energy dissipation effect, avoiding interference between the vibration assembly and the spring switch assembly during vibration, resulting in continuous vibration.

[0052] The operating principle of the spring vibration delay switch in this solution is mainly based on spring force and vibration conduction. When a certain vibration or impact force is applied to the switch from the outside, the spring will generate corresponding vibrations. Such vibrations will trigger the mechanical or electronic components inside the switch, thereby changing the state of the circuit. Specifically, the spring vibration delay switch contains a spring electrode inside. When triggered by an external vibration, the electrode will generate a signal, which will trigger the conduction of a triode, and then charge a capacitor. The voltage formed by the capacitor will maintain the conduction of a field effect transistor, enabling the vibration block 3 to work. When the vibration stops, the capacitor will gradually discharge. After the discharge is complete, the field effect transistor enters the cut-off state, and the vibration block 3 stops working, thus achieving the delay effect.

[0053] First, in this solution, the lid 27 at the nose of the plush outer part 1 is opened, and spices or solid perfume is placed inside the spice box 23 for storage. Every time the user squeezes the plush outer part 1, the gas inside the second return airbag 22 or the first return airbag 21 will be discharged into the spice box 23, driving the spices inside the spice box 23 to diffuse, and finally discharged from the sound hole 283 of the whistle mechanism 28, so that the plush outer part 1 emits fragrance and produces a whistling sound effect.

[0054] Specifically, when the gas is squeezed into the spice box 23, it will lift and drive the square plate 29 to move horizontally. The return spring 293 is compressed, the square plate 29 is separated from the sealing baffle 291, and the crushing arm 292 is driven to move, and the spices are squeezed and crushed. The air flow will fully contact the spice material through the flow channel. After the air flow is discharged, the square plate 29 will reset under the action of the return spring 293 and return to the state of contacting the sealing baffle 291, thereby closing the air inlet between the sealing baffles 291 and preventing the gas from flowing back.

[0055] The gas enters the whistle mechanism 28 after passing through the spice box 23. The gas is guided and accelerated by the guide block 281 and finally discharged through the sound hole 283. During this process, the speed and path of the air flow change significantly at the air inlet, forming a vortex that triggers vibration, so that the whistle mechanism 28 produces a whistling sound, improving the attractiveness and interest of the plush toy. At the same time, if the cover 282 is removed, the inner cavity of the whistle mechanism 28 can be exposed, and the air flow can be discharged without passing through the sound hole 283, thus avoiding the generation of whistling sound and disturbing the residents.

[0056] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
