Therefore, in this example, the fan 226 is movable so 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 to the surrounding air better.

In this embodiment, the air inlet 222 is positioned directly behind the air outlet 224, and the diffusion member 232 is configured to be located 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, pass through the diffusion member 232, and exit through the air outlet 224. The advantage of this configuration is that before the air is discharged through the air outlet 224, most of the air can pass through the diffusion member 232, thereby allowing the chemical substances to diffuse well into the air.

Preferably, the opening 226 of the container 230 is configured as a button on the housing 220. The opening 226 contains a spring (not shown) so that when the button is pressed, the catheter 234 can be opened to refill the container 230 with chemicals. This has the advantage that the configuration reduces the force to open the catheter and facilitates operation.

In this embodiment, the device 400 for diffusing chemical substances includes a housing 401 having a chamber 404 having an air inlet 406 and an air outlet 408. The device is configured with a diffusion member 410, an ionization member 412, and a fan 414 in the chamber 404, the fan 414 is configured to drive air from the air inlet 406, and then pass through the air inlet 406 and the In the chamber 404 between the air outlets 408, air passes through the diffusion member 410 and the ionization member 412 provided in the chamber 404, and then is further discharged to the surroundings through the air outlet 408. The air inlet 406 and the air outlet 408 are positioned so that most of the air flowing from the air inlet 406 and the air outlet 408 passes through the chamber 404 The diffusion member 410 and the ionization member 412. Preferably, the air outlet 406 is configured to discharge 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 in the lower part. The container 416 has a conduit 420 that extends to an opening 418, which is configured to serve as a The button, in turn, provides an accessible opening 418 which may contain a spring (not shown) so that when the button is pressed, the catheter 420 can be opened. Thus, the container 416 is refilled with chemicals through the accessible opening 418. The device 400 is supported by a base 422 below the container 416, and at the same time, a power port 424 is configured adjacent to the base 422 to connect an external power source. The power port 424 can also be configured anywhere in the device 400.

As shown in FIG. 12, in this embodiment, the chamber includes a channel 434 configured to accommodate at least part of the diffusion member 410 and the ionization member 412, and the channel 434 and the air inlet 406 and the air outlet 408 are in fluid communication. The diffusion member 410 may be disposed adjacent to the ionizing member 412, opposite to the ionizing member 412, and/or in the same plane as the ionizing member 412. In this embodiment, the diffusion member 410 is configured to face the ionization member 412, that is, the outlet of the diffusion member 410 faces a surface of the ionization member 412. When the device 400 is in operation, air enters the chamber 404 through the air inlet 406 and flows through the channel 434 that houses a portion of the diffusion member 410 and the ionization member 412. In the channel 434, air is mixed with the chemical substance diffused into the channel and/or ionized by the ionization member 412, and then, the air with the diffused chemical substance and/or ion is discharged to the surroundings through the air outlet 408. Without wishing to be bound by theory, it is believed that the setting of the channel 434 makes the driven air flow more concentrated, and can effectively and quickly spread most of the chemical substances diffused in the channel to the surrounding space, reducing the waste of chemical substances and reducing Condensation in undesirable places and reduce the probability of pollution. Moreover, the ionized air can be effectively transferred to the surroundings, reducing the backflow to other parts of the chamber to cause waste.

It is understandable that those skilled in the art can adjust the positions of the diffusion member and the ionization member in the chamber according to actual needs.

In this embodiment, the diffusion member 410 has a heating element 426 and a liquid wick 428. The liquid wick 428 transfers chemicals to the heating element 426 by capillary action for corresponding heating. Optionally, the liquid wick 428 may be a mechanical pump or an electric pump. The heating element may be selected from any electric heater, catalytic burner, etc. Preferably, the heating element 426 is also provided with a heat insulation plate 430 to separate the heating element from the adjacent member or device structure, and the heating temperature may be the aforementioned temperature, that is, if it is heated to 50 degrees Celsius to Between 90 degrees. After the chemical substance is heated correspondingly, the chemical substance diffuses into the air in the chamber 404 or the channel 434.

As shown, the diffusion member 410 is configured with a sensor 432 to sense the amount of liquid carried in the container 416. The sensor 432 is attached to the wick 428 to sense the degree of residual chemicals in the container 416, thereby transmitting information about the amount of residual chemicals to the diffusion member 410 and/or controller connected thereto. The controller can operate as in the previously described embodiment, such as 302 shown in FIGS. 1 to 4, and interact with the sensor 432, for example, when the amount of liquid in the container 416 is nearly insufficient or is insufficient to use A notification is issued to remind the user to refill the container 416; and/or to automatically adjust the parameters of the diffusion chemical substance, such as temperature, fan rotation rate, etc. Without wishing to be bound by theory, it is believed that this arrangement is particularly advantageous. When the liquid is to be depleted or has been depleted, the sensor 432 feeds back the data to the controller, and the controller can issue an instruction to stop the operation of the diffusion member 410 In order to reduce or prevent the device 400 from consuming energy, idling, overheating, etc. without chemicals.

In this particular embodiment, the ionization member 412 further enhances the usability of the device 400. The ionizing member 412 is a member capable of generating negative ions and positive ions, and is preferably a member generating negative ions. The ionizing member 412 may be constituted by an energized negative ion needle, negative ion coil, and/or conductive surface. Specifically, the ionizing member 412 provided in the chamber 400 ionizes air particles in contact with the ionized surface through one of its ionized surfaces, so that the air particles carry positive ions or negative ions. Optional Ground, other members that can generate positive or negative ions in the art can be used. The arrangement of the ionizing member improves the effect of improving the surrounding air quality. This is because pollutants, dust, bacteria, pathogens, etc. usually carry positive ions, and ionized air particles usually carry negative ions. They can further combine with pollutants, pathogens, etc. in the surrounding air to increase or decrease their weight. On the ground or attached to walls or objects, reduce the presence of pollutants, disease sources, etc. in the surrounding air, thereby improving air quality. The inventor believes that the device having the diffusion member 410 and the ionization member 412 can achieve a double-gain effect in improving air quality.

Furthermore, during the operation of the apparatus 400, the diffusion member 410 and the ionization member 412 may be operated in a synchronized or asynchronous mode. In the synchronous working mode, the diffusion member 410 and the ionization member 412 operate simultaneously to diffuse the chemical substance into the chamber 404 or the channel 434, and ionize the air passing through, and the treated air is then from the air outlet 408 Discharge and spread well to the surrounding air.

In a preferred embodiment, the diffusion member 410 and the ionization member 412 operate in an asynchronous operation mode, that is, when the device 400 is operating, only one of them operates. Without being limited by theory, it is believed that the user can select an appropriate working mode according to the needs of the environment, and in order to maximize the diffusion effect and/or the ionization effect, it is preferable that both the diffusion member 410 and the ionization member 412 operate alternately. Specifically, a corresponding time period may be preset, for example, a time period of about 5 minutes to about 3 hours, and the diffusion member 410 and the ionization member 412 sequentially run in turn according to the preset or user-selected time period. Alternatively, the user may select only the diffusion member 410 or the ionization member 412 to perform the corresponding diffusion or ionization operation.

Further, in this embodiment, the device 400 is equipped with various sealing tapes and/or sealing rings to reduce unnecessary leakage of chemicals (especially highly volatile chemicals such as aromatic compounds) to the outside of the container 416 Or unnecessary leakage at the connection between different parts. As shown in FIG. 12, for example, a seal ring 436 is arranged between the container 416 and the chamber 404; seal rings 438, 440 are arranged on different parts 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.
