Liquid Diffusing System

Technical Field of the Invention

The present invention relates to the field of spraying mist, and more particularly, to a system for dispensing mist bearing substances including scent, nutraceutical, pharmaceutical, flavoring, medicine, and the wireless control of the dispensation in the air.

Background of the Invention

Traditional liquid dispensing systems often use other materials to aid in the dispensation of the liquid, including water, solvent and heat. A breakdown of commonly found diffusers are explained below:

1. Evaporative Diffuser

Examples of this type of diffuser are reed diffusers, or diffusers that use scented beads. Most evaporative diffusers need extra materials such as the reed or beads, which influence liquid purity and in some cases may interact with the chemical components of the liquid. Some reed diffusers also add extra chemicals so that the liquid can travel up the reed sticks more quickly. Without the help of fan or sufficient air flow, it is hard for the liquid to be dispersed in the room.

2. Heat Diffuser

Examples of this type are burning diffusers, or candle diffusers that heat up the liquid. This type of diffuser is dangerous because it involves open fire, and the heat may also change the molecular makeup of the liquid to be diffused.

3. Humidifying/Ultrasonic Diffuser

Ultrasonic diffusers use water as medium for the desired liquid to be dispensed. Ultrasonic diffusers add humidity into the air, making them the perfect choice for dry regions or constant users of air conditioning. However, this added humidity can also cause problems starting from moldy furniture, wet stains and clammy feeling especially for regions with humidity. This type of diffuser also needs frequent water refill and cleaning. With the high volume of water needed, usually ultrasonic diffusers have a larger size, and can spill easily.

4. Nebulizing Diffuser

Nebulizing diffusers follow the Bernoulli theorem, where pumped air blows and transforms the desired liquid into micro-particles. It does not require the addition of other materials, allowing nebulizing diffusers to preserve the purity of the liquid to be dispensed. This is why nebulizing diffuser method is this diffusion method of choice for as the basis of this invention. Most nebulizing diffusers use a nozzle that helps to transform the liquid into micro-particles, that is attached to the body of the diffuser. With prolonged usage, this can create clogging and sanitary problem which requires frequent cleaning of the diffusers, so there is a need to separate the nozzle from the diffuser body. Some nebulizing diffusers also require users to screw in liquid containers into the diffuser, often causing in leakage and also consumes time, thus it is more preferable if liquid containers do not need to be screwed in yet can be sealed tightly.

Moreover, liquid that is dispensed for the benefit of inhalation is not suitable for prolonged inhalation. For example, inhalation of Lavandula angustifolia vapor is suitable for evenings as it lowers anxiety and promotes restful sleep. However, it is not suitable for mornings or when users want to concentrate. Therefore, more than one liquid container is necessary inside one diffuser. Furthermore, it is important to be able to schedule different liquid to be dispensed at different times, based on the needs of the user.

In addition, traditional diffusers do not have monitoring properties. It is unable to track the environmental condition, usage of the liquid, behavior of the user when using the dispenser, or the status of the diffuser (e.g. working properly, broken, clogged).

Traditional art also do not collect data from the diffusers or user behavior, which could be analyzed to create insights about the interaction between users and the system or the liquid in the system. For example, through data tracking and analysis it could be discovered that palliative care patients who have difficulty sleeping prefer Citrus sinensis vapor, and further analysis could lead to the discovery that the said vapor reduces the feeling of pain for the users that allow them to sleep better.

Therefore, it is critical to improve the existing traditional diffusers commercially available so as to obtain new liquid diffusion system for users that can provide clean mist with remote control of various liquid containers and a plurality of diffusers.

Summary of the Invention

The base 10 with opening at upper end has a cavity therein for accommodating a liquid container 150, the platform 20 is configured to connect the liquid container 150 and be subject to external force from one end of the platform 20. The diffuser can be shaped differently to accommodate different design of the container 150, if desired. The container 150 is located in the cavity of the base 10 for containing liquid, including but not limited to scent, nutraceutical, pharmaceutical, flavoring, medicine. Preferably, the container 150 can be an aluminum, plastic or glass bottle.

One end of the chamber 130 is connected to the nozzle 140 and the other end of which is connected to the platform 20. The nozzle 140 is connected with the chamber 130 for flowing air in the chamber 130 into the container 150 and sucking up liquid from the container 150. By this structure, liquid flows into the nozzle 140, and the nozzle 140 turns the liquid into micro-particle by Bernoulli’s principle. Thus micro-particle of liquid is dispensed in the chamber 130 and inside container 150 that is filled with air, but liquid itself flows back to liquid part of the container 150 and the tube 141 connected to the nozzle 140.

A sealing member engaged with the chamber 130 for sealing the chamber 130 and the nozzle 140 is also provided.

When air current is supplied, difference in pressure causes suction of the liquid from liquid container 150; and liquid that is sucked meets pressurized air in chamber 130 is dispensed the liquid into micro-particles. Further, remaining liquid in the chamber 130 is returned into the liquid container 150 via the nozzle 140.

And accordingly, the system further comprises a trigger like a motor for triggering the locking member to change the state between the chamber 130 and the nozzle. For example, it can change the state between the chamber 130 and the nozzle 140 from releasing to sealing, and vice versa; it can also change the state between the chamber 130 and the nozzle 140 from sealing to releasing.

In another embodiment of the present invention, the liquid diffusing system of the present invention is further provided with a tray 160 located in the cavity of the base 10 for receiving a plurality of containers 150.
