[0030] 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.

[0031] The purpose of the present invention is to provide a projection device that can be built into an inflatable product to solve the problems existing in the prior art.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Embodiment 1:

[0034] This embodiment provides a projection device that can be built into an inflatable product, such as Figure 1-3 , 6-9, comprising an inflatable cloth cover 1, a projection device 2 and an audio playback device are fixed inside the inflatable cloth cover 1, an imaging space is provided between the front end of the projection device 2 and the inflatable cloth cover 1, and the projection device 2 and the audio playback device are wirelessly connected to the smart terminal.

[0035] As an implementation mode, the audio playback device includes at least a control panel, a speaker, a microphone, an audio playback module, and a Bluetooth module. When in use, the audio can be recorded through the microphone or sent through a smart terminal, and processed by the audio playback module, such as changing the voice, adjusting the speed, reducing the noise, etc. of the recorded or uploaded audio, and then played through the speaker, thereby improving the interactive display effect.

[0036] As an implementation mode, the inflatable cloth cover 1 is provided with an air charging and discharging port, and the inflatable cloth cover can be inflated by connecting an air pump. The air charging and discharging port is externally connected to a DC blower, thereby avoiding or reducing air leakage, so that the inflatable cloth cover can remain inflated for a long time.

[0037] As an implementation mode, the inflatable cloth cover 1 adopts a cartoon-shaped structure. In the present embodiment, the inflatable cloth cover 1 adopts a pumpkin shape. Of course, in other embodiments, cartoon shapes such as cartoon characters may also be adopted.

[0038] As an embodiment, the projection device 2 includes a shell 21, a mounting base 29 is provided on the outside of the shell 21, and a heat sink, a built-in fan, a main control system IC22, a grating generator 23, a video screen 24, and a lens imaging lens 25 are provided in the shell 21 from back to front. The main control system IC22 is connected to an external power cord 26. After power is connected, the main control system IC22 controls the grating generator 23 to generate a grating, and after passing through the shielded video screen 24 and the lens imaging lens 25, the video or image is projected in front, so that the surface of the cloth cover has an image display effect, and the built-in fan can quickly transfer the heat generated by the light source to the heat sink, and then discharge it to the outside to prevent the projection device from overheating.

[0039] As an implementation method, Fig.10 As shown, a temperature control switch is provided on the heat sink, which can control the light source to cut off the power when the temperature is higher than 85°C, thereby avoiding equipment damage or fire caused by overheating. After the temperature drops to 65°C, the power supply is restored, so that the projection device 2 can operate stably and safely.

[0040] As an implementation method, the video screen 24 is an LCD screen.

[0041] As an implementation manner, the imaging lens 25 is provided with a focus adjustment component 27, so as to facilitate the adjustment of the focus to make the picture clear.

[0042] As an implementation mode, in addition to playing video images, the projection device 2 can also be used as a light, by emitting multi-color light to flicker and pulsate, thereby improving the display effect.

[0043] As an implementation mode, the projection device 2 is provided with a control button, which can be controlled when the control button is exposed. Of course, if the projection device 2 is completely hidden in the inflatable cloth cover 1, an infrared remote control sensing module, a Bluetooth module, a WiFi module and an APP module can be used for remote control or network control. When Bluetooth is used for connection control, the user can speak or play remotely through the mobile phone, thereby effectively improving the functionality.

[0044] As an implementation method, multiple projection devices in different inflatable products can also be interconnected to achieve a linkage effect. The control module of one of the projection devices controls the other projection devices to alternately change or cooperate with each other in expression to achieve an interactive animation effect. The interactive forms include sound and animation video; for example, if one of the inflatable pumpkin models sings or makes an animated expression, the three inflatable doll models next to it will sing duet or make echoing expressions, thereby realizing an interactive linkage scene.

[0045] As an implementation mode, the mounting seat 29 is disposed at the rear end of the shell 21, and the edge of the mounting seat 29 is connected to the inflatable cloth cover 1 through the snap 28 to achieve a stable connection between the two.

[0046] Embodiment 2:

[0047] As a variation of Example 1, this embodiment provides a new installation method, such as Figure 4 As shown, the mounting seat 29 is arranged in the middle of the shell 21, and the edge of the mounting seat 29 is connected to the inflatable cloth cover 1 through the snap button 28, so that the rear end of the shell 21 can be exposed to the outside, which is convenient for setting interfaces, buttons and other components.

[0048] Except for the above-mentioned installation method which is different from that of Example 1, the rest of the structures and principles are the same as those of Example 1.

[0049] Embodiment 3:

[0050] As a variation of Example 1, this embodiment provides a new installation method, such as Figure 5 As shown, a mounting plate 3 is suspended in the middle of the inflatable cloth cover 1. The mounting plate 3 can be integrally provided with the inflatable cloth cover 1 or independently connected. The mounting seat 29 is provided at the bottom of the shell 21. The edge of the mounting seat 29 is connected to the mounting plate 3 through a snap 28. In this way, the projection device 2 can be installed in the middle of the inflatable cloth cover 1, thereby achieving better protection.

[0051] It should be noted that, since the mounting plate 3 is suspended, the mounting plate 3 will inevitably tilt after the projection device 2 is installed. In this case, the projection device 2 can be propped up by providing an inclined pad to ensure a good projection effect.

[0052] Except for the above-mentioned installation method which is different from that of Example 1, the rest of the structures and principles are the same as those of Example 1.

[0053] The present invention provides a projection device that can be built into an inflatable product. By combining the projection device with the inflatable cloth cover, the projection device has a larger imaging distance and a wider imaging range, and the video picture is dynamically displayed on the surface of the inflatable cloth cover, thereby improving the display effect of the inflatable cloth cover. At the same time, the projection device has a variety of installation and connection methods, which can meet different installation requirements.

[0054] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
