Description

Technical Field

[0001] The invention relates to the technical field of odor playing equipment, in particular to a digital odor capsule. Background Art

[0002] Traditional scent boxes and other scent materials all utilize the principle of gas diffusion to release scent into indoor or outdoor spaces, or enhance the speed and concentration of scent release by heating or increasing air flow.

[0003] With the continuous development of virtual reality technology, people's requirements for immersive experience are getting higher and higher. In a virtual environment, vision, hearing, touch, can not replace the role of smell, olfactory perception is an indispensable and important part of the virtual reality system. In the experience of movies and advertisements, the addition of smells that match the scene can make people feel more immersive.

[0004] The equipment used for playing smells generally includes an air pump and an air circuit. A storage device for smell raw materials is arranged on the air circuit. The smell emitted by the smell raw materials is carried by the gas flowing through the surface of the smell raw materials, and the smell is spread out by the diffusion of the gas in the external environment. The storage device for smell raw materials is very important. It needs to be able to store the smell raw materials for a long time, and also be able to control the gas flow that enters and flows out. The air circuit needs to be closed when the smell does not need to be emitted, and the air circuit needs to be opened when the smell is emitted. Summary of the invention

[0005] The present invention aims to solve the problems that the gas raw material storage device in the existing odor playing equipment needs to store the odor raw materials for a long time to ensure that the odor is not lost, and also needs to control the on-off of the gas path to ensure that the odor is emitted on demand. The present invention provides a digital odor capsule with a reasonable structure, which can seal and store the odor raw materials when not in use, can safely connect the gas path when in use, and can accurately play the odor.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A digital odor capsule comprises a box body, wherein an odor raw material capable of emitting an odor is stored in the box body, the box body is provided with a first through hole and a second through hole, the box body is provided with a silo and a circuit board, the silo stores the odor raw material, the silo is provided with a first solenoid valve and a second solenoid valve, the first solenoid valve and the second solenoid valve are respectively provided with an air inlet and an air outlet, the air outlet of the first solenoid valve and the air inlet of the second solenoid valve are respectively connected to the interior of the silo, the first through hole allows the air inlet of the first solenoid valve to pass through, the second through hole allows the air outlet of the second solenoid valve to pass through, the first solenoid valve and the second solenoid valve are respectively electrically connected to the circuit board, and the circuit board is provided with a data plug and an indicator light.

[0008] Preferably, the box body is cylindrical, and is provided with a main body bracket. The main body bracket is provided with a head end having the same outer contour as the box body, and the main body bracket is also provided with a cylindrical bracket body that can be extended into the box body. The silo, circuit board, first solenoid valve, and second solenoid valve are all fixed in the bracket body. One end of the box body can accommodate the bracket body for insertion, and the other end of the box body is provided with a closed box cover. The head end is provided with a first through hole and a data hole for accommodating a data plug to pass through, and the closed box cover is provided with a second through hole and a lamp hole for accommodating an indicator light to pass through.

[0009] Preferably, the first solenoid valve and the second solenoid valve have the same structure, including a magnetizable iron shell, the iron shell including a coil, the coil being electrically connected to the circuit board, an air inlet end and an air outlet end being respectively arranged at both ends of the iron shell, the air inlet end being provided with an air inlet, the air outlet end being provided with an air outlet, a moving iron and a spring being arranged inside the iron shell, one end of the spring being fixed to the air inlet end or the air outlet end, the other end of the spring being fixed to the moving iron, and the moving iron being arranged between the air inlet end and the air outlet end.

[0010] Preferably, the air inlet end is pluggably connected to the iron shell, one end of the air inlet end extends into the iron shell, and a sealing ring is provided between the outer side of the extended end of the air inlet end and the inner wall of the iron shell.

[0011] Preferably, the iron shell is cylindrical, the air inlet and the air outlet are circular through holes coaxial with the iron shell, and the air inlet end surface is also provided with a radial guide groove connected to the air inlet.

[0012] Preferably, rubber pads are provided on the end surfaces of the moving iron that contact the air inlet end and the air outlet end.

[0013] Preferably, a sealing plug is provided on the air inlet of the first solenoid valve and the air outlet of the second solenoid valve respectively, and the sealing plug comprises a sealing section and a hand-held section.

[0014] Preferably, the shape of the hand-held section of the sealing plug is the same as that of the box body.

[0015] Preferably, the box body is cylindrical, and box covers are respectively provided at both ends of the box body. The first through hole and the second through hole are respectively located on the box covers at both ends of the box body. Among the two box covers, one box cover is provided with a data hole for allowing a data plug to pass through, and the other box cover is provided with a lamp hole for allowing an indicator light to pass through.

[0016] This solution consists of a control module (circuit board, solenoid valve) and an odor module (silo, odor raw materials in the silo). When working, the capsule-like odor container (capsule) of this solution is installed on the host, connected to the host circuit board through a data plug, and the host controls the solenoid valve in the capsule to open. The air pump air enters the odor capsule from the air inlet, and the air flow flows through the odor raw materials in the silo to bring out the odor and blow it out from the air outlet. This solution pioneered the use of the sealing performance of the solenoid valve when it is closed to preserve the odor raw materials, reducing the loss of odor raw materials in the non-working state, making the odor raw materials have a longer shelf life, a higher degree of odor restoration, and a longer life.

[0017] When the solenoid valve coil wire of this scheme is energized, the coil generates a magnetic field to magnetize the iron shell and attract the moving iron. At this time, the rubber pad at the air inlet end fits with the air inlet end, the rubber pad at the air outlet end opens, and the gas fluid flows to the air outlet end through the guide groove to realize the gas fluid passage; when the solenoid valve coil wire is de-energized, the spring makes the moving iron fit with the air outlet end, and the rubber pad at the air outlet end closes to realize the gas fluid circuit break. The advantages of the solenoid valve of this scheme are that the diameters of the air inlet and air outlet ports are large, the gas fluid resistance is small, the gas fluid pressure loss is small, and the rubber pads at both ends of the moving iron can effectively reduce the noise generated by the moving iron hitting the two ends when the solenoid valve is working.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The sealing performance of the solenoid valve when closed is used to preserve the odor raw materials, which reduces the loss of odor raw materials in the non-working state, making the odor raw materials have a longer shelf life, a higher odor restoration degree, and a longer life.

[0020] 2. The solenoid valve is easy and accurate to control. When multiple digital odor capsules storing different odor materials work together, it is convenient to control the designated digital odor capsule to connect or disconnect the gas path, so as to emit the required odor.
