As shown in FIGS. 3 and 4, a container 206 as a container or can of a chemical can include a conduit 208 that is configured to extend to an opening 210 in the housing 102. This has the advantage that the housing 102 does not need to be removed to open the container 206, thereby reducing the time and effort required to refill the container 206. As shown in FIG. 5, the catheter 208 is sealed by a piston-type plug 214 inserted into the catheter 208 to seal the container 206. The piston-type plug 214 is also pivotally coupled to the opening 210 such that when the opening is rotated upwardly, the piston-type plug 214 is lifted from the conduit to open the container 206. To seal the container 206, the piston-type plug 214 is inserted into the conduit 208 by a pivoting action of the opening 210 and pushed down into the conduit 208.

Preferably, the apparatus 100 also includes a weighted base 110 made of a heavier material such as metal, stone, or ceramic, the base 110 being disposed below the container 206. The base 110 provides stability to the device 100 and reduces the likelihood of tipping of the device 100 as the container 206 approaches empty. As shown in this example, the air outlet 108 is also disposed at an angle relative to the base 110, that is, at an angle from a vertical axis extending from the base 110. Preferably, the angle is relative to the base 110 At about 45°, the air within the chamber 104 can be expelled in a generally lateral and upward profile while the operation and the weighted base 110 assist in stabilizing the device 100 on a surface.

In the present embodiment, the device 100 is powered by an external power source that is coupled to a power port 402 disposed within the device 100 adjacent to the base 110. It will be understood by one of ordinary skill in the art that the power port 402 can be placed anywhere on the device 100.

In other embodiments, the housing 102 can also include a solar panel to provide a power to operate some or all of the components of the device 100.

An advantage of an embodiment of the apparatus 100 is that the apparatus 100 can be utilized in a more efficient manner to spread chemicals, particularly in large spaces, such as in the lobby or lobby. The chemical substance can be more efficiently diffused by using a controlled heating diffusion member and a fan member, and providing the diffusion member between the air inlet and the air outlet to approach or be adjacent to the position where the air flows. For example, compounds for aromatherapy. In addition, the heated diffusion member also helps to destroy pathogens in the air, so the device can also provide cleaning or antibacterial benefits, thereby enhancing the comfort of the environment in which the device is operated.

Referring to Figures 6 through 10, there is shown an apparatus 200 in accordance with another implementation of the present invention. As shown, the device 200 includes a housing 220 having an air inlet 222 and an air outlet 224. The device 200 has a fan 226 configured to drive air from the air inlet 222 and then through a diffusing member 232 disposed between the air inlet 222 and the air outlet 224 disposed within the chamber. The air is mixed with the diffused material and further discharged to the periphery via the gas outlet 224.

In the present embodiment, the apparatus 200 also includes a container 230 positioned in the lower portion of the apparatus 200 and having a conduit 234 extending to an opening 236 that is configured to act as a housing on the housing. A button, in turn, provides an access opening through which the container is refilled with chemicals. A base 240 supports the device, and the base 240 is disposed below the container 230. A power port 260 is configured adjacent to the base 240 to connect to an external power source. This power 埠 can also be configured anywhere in the device 200.

As shown in Figures 8 through 10, the fan 226 is coupled to a rotatable ball bearing assembly 228 to provide a movable engagement for engaging the fan to the device. Thus, in this example, the fan 226 is movable such that the direction of the air flowing from the device 200 is adjustable. This has the advantage that the adjustable fan allows the scented air discharged from the air outlet 224 to diffuse better to the surrounding air.

In the present embodiment, the air inlet 222 is directly positioned behind the air outlet 224, and the diffusion member 232 is disposed between the air inlet 222 and the air outlet 224 in the chamber. This configuration allows air driven by the fan 226 to flow directly from the air inlet 222, through the diffusing member 232, and exit through the air outlet 224. An advantage of this configuration is that most of the air can pass through the diffusing member 232 before the air is discharged through the air outlet 224, thereby allowing the chemical to diffuse well into the air.

Preferably, the opening 226 of the container 230 is configured to act as a button on the housing 220. The opening 226 includes a spring (not shown) such that when the button is depressed, the conduit 234 can be opened to refill the container 230 with chemicals. This has the advantage that this configuration reduces the force of opening the catheter for ease of operation.

Referring to Figures 11 through 12, there is shown another apparatus for diffusing a chemical according to the present invention, comprising: a chamber, a diffusion member and an ionization member, the diffusion member being configured to chemically The substance diffuses into the air in the chamber, the ionization member being configured to ionize air within the chamber; wherein the chamber is in communication with an air inlet and an air outlet, the air inlet being configured to Air is received from outside the chamber, the air outlet being configured to vent air from the chamber.

In this embodiment, the apparatus 400 for diffusing chemicals includes a housing 401 having a chamber 404 having an air inlet 406 and an air outlet 408. The device is configured in chamber 404 with a diffusing member 410, an ionizing member 412, and a fan 414 that is configured to drive air from the inlet 406 and then pass through the inlet 406 and the The chamber 404 between the air outlets 408, the air passes through the diffusing member 410 and the ionizing member 412 disposed in the chamber 404, and is then further discharged to the periphery via the air outlet 408. The air inlet 406 and the air outlet 408 are positioned such that most of the air flowing from the air inlet 406 and the air outlet 408 passes through the diffusion member 410 of the chamber 404 and the ionization member 412. Preferably, the air outlet 406 is configured to vent air at an angle relative to an axis of a base 422, and the angle is an acute angle.

The device 400 further includes a container 416 for storing chemicals therein, the container 416 having a conduit 420 extending to an opening 418 as described above, the opening 418 being configured as a member on the housing The button, in turn, provides an accessible opening 418 that can include a spring (not shown) such that when the button is depressed, the catheter 420 can be opened. Thus, the container 416 is refilled with chemicals by the accessible opening 418. The device 400 is supported by a base 422 below the container 416, while a power port 424 is configured adjacent to the base 422 for connection to an external power source. The power port 424 can also be configured anywhere in the device 400.

As shown in FIG. 12, in the present embodiment, the chamber includes a passage 434 configured to receive at least a portion of the diffusion member 410 and the ionization member 412, and the passage 434 and the intake port 406 and the air outlet 408 are in fluid communication. The diffusion member 410 can be disposed adjacent to the ion The member 412 is opposite the ionization member 412 and/or is in the same plane as the ionization member 412. In the present embodiment, the diffusion member 410 is disposed opposite the ionization member 412, that is, the outlet of the diffusion member 410 faces a surface of the ionization member 412. While the device 400 is in operation, air enters the chamber 404 through the air inlet 406 and flows through a passage 434 that houses a portion of the diffusing member 410 and the ionizing member 412. In channel 434, air is mixed with and/or ionized by chemicals diffused into the channel, and then air with diffused chemicals and/or ions is expelled through the gas outlet 408 to the periphery. Without wishing to be bound by theory, it is believed that the arrangement of the channel 434 allows the driven air to be more concentrated, effectively and quickly spreading most of the chemical material diffused in the channel to the surrounding space, reducing chemical waste and reducing Condensation in undesired places and reducing the chance of contamination. Also, the ionized air can be effectively delivered to the surrounding area, reducing backflow to other parts of the chamber to cause waste.

It can be understood that the position of the diffusion member and the ionization member in the chamber can be adjusted according to actual needs by those skilled in the art.

In the present embodiment, the diffusion member 410 has a heating element 426 and a wick 428, and the wick 428 transfers the chemical to the heating element 426 by capillary action for corresponding heating, optionally, the wick 428 can be a mechanical pump or an electric pump. The heating element can be selected from any of an electric heater, a catalytic burner, and the like. Preferably, the heating element 426 is also provided with a heat shield 430 to separate the heating element from the adjacent component or device structure, and the heating temperature may be as described above, ie, heating to a temperature of 50 degrees Celsius to Between 90 degrees. When the chemical is heated accordingly, the chemical diffuses into the air in chamber 404 or channel 434.

As shown, the diffusion member 410 is configured with a sensor 432 to sense the amount of liquid carried within the container 416. The sensor 432 is attached to the wick 428 to sense the extent of residual chemicals in the container 416 to transfer residual chemicals to the diffusion member 410 and/or controller coupled thereto. The amount of information. The controller can operate as in the previously described embodiment, 302 as shown in Figures 1-4, and interacts with the sensor 432, such as when the amount of liquid in the container 416 is near insufficient or insufficient for use. A notification is sent to remind the user to refill the container 416; and/or to automatically adjust parameters of the diffusion chemistry, such as temperature, fan turnover, and the like. Without wishing to be bound by theory, it is believed that this arrangement is particularly advantageous. When the liquid is to be depleted or depleted, the sensor 432 feeds the data back to the controller, and the controller can issue an instruction to stop the operation of the diffusion member 410. Thereby, the device 400 is reduced or prevented from consuming energy, idling, overheating, etc. in the absence of chemicals.

In this particular embodiment, the ionization member 412 further enhances the usability of the device 400. The ionization member 412 is a member capable of generating negative ions and positive ions, and is preferably a member that generates negative ions. The ionization member 412 can be formed by an energized negative ion needle, a negative ion ring, and/or a conductive surface or the like. Specifically, the ionization member 412 disposed in the chamber 400 ionizes the air particles in contact with the ionized surface through its ionized surface to cause the air particles to carry positive ions or negative ions. Alternatively, other components that can produce positive or negative ions in the art can be used. The provision of the ionizing member improves the effect of improving the ambient air quality. This is because pollutants, dust, bacteria, pathogens, etc. usually carry positive ions, and ionized air particles usually have negative ions, which can further combine with pollutants and pathogens in the surrounding air to increase their weight and decrease. On the ground or attached to a wall or object, reduce the presence of pollutants, pathogens, etc. in the surrounding air, thereby improving air quality. The creators believe that a device having a diffusing member 410 and an ionizing member 412 can achieve a double gain effect in improving air quality.

Moreover, when the device 400 is in operation, the diffusion member 410 and the ionization member 412 can be operated in a synchronized or asynchronous mode of operation. Diffusion member 410 and ionization member 412 in a synchronized mode of operation Simultaneously operating to diffuse chemicals into the chamber 404 or channel 434 and ionizing the flowing air, the treated air is then discharged from the gas outlet 408, diffusing well to the surrounding air.

In the preferred embodiment, the diffusing member 410 and the ionizing member 412 are operated in an asynchronous mode of operation, i.e., when the device 400 is in operation, only one of them operates. Without being bound by theory, it is believed that the user can select a suitable mode of operation according to environmental needs, and to maximize the diffusion effect and/or ionization effect, it is preferred that both the diffusion member 410 and the ionization member 412 operate alternately. Specifically, a corresponding period of time may be pre-set, for example, a period of about 5 minutes to about 3 hours, and the diffusion member 410 and the ionization member 412 are sequentially operated in accordance with a preset or user-selected period of time. Alternatively, the user may select only the diffusion member 410 or the ionization member 412 for a corresponding diffusion or ionization operation.

Further, in the present embodiment, the device 400 is provided with various sealing tapes and/or sealing rings to reduce unnecessary leakage of chemicals (especially highly volatile chemicals such as aromatic compounds) outside the container 416. Or unnecessary leakage at the joint between different parts. As shown in FIG. 12, for example, a seal ring 436 is disposed between the container 416 and the chamber 404; seal rings 438, 440 are disposed on different members of the diffusion member 410; and a seal at the junction of the diffusion member 410 and the chamber 404 Ring 442; and sealing ring 444 at opening 418.

It will be understood by those skilled in the art that many variations and/or modifications of the specific embodiments shown in the present invention are not departing from the spirit or scope of the invention. Therefore, all the examples are to be considered as illustrative and not limiting.
