A scent device comprises a container defining a volume and configured to hold a fill material, which may include one or more chemical compounds, natural formulations, or both configured to absorb odor and/or moisture, and/or emit a scent. The scent device includes a vented cap reversibly coupled to the container via a connection mechanism, and a breathable insert sandwiched between the container and the cap. The breathable insert may comprise a non-woven fabric supported along its perimeter by a structural mount. Methods of manufacturing the scent device involve cutting a mount from a support material, attaching a breathable material to the mount to form a breathable insert, depositing a scent-controlling material within a container, and sandwiching the breathable insert between the container and a cap upon coupling the cap with the container.

The present invention discloses a dehumidification bag capable of being placed in multiple forms, having a bag body and a moisture absorbing medium placed in the bag body, wherein the surface of the bag body is provided with a gas permeable zone, the rest is a sealing zone except for the gas permeable zone, and the moisture absorbing medium absorbs moisture in air through the gas permeable zone; and the bottom of the bag body is provided with an expanding portion that allows the bag body to be placed upright. The present invention has the following beneficial technical effects: the present invention is simple in structure and convenient to use; the present invention not only reduces the use of space, but also maximizes the applicable range; secondly, since the present invention is suitable for different placement postures, it can be placed freely on the premise of ensuring that the gas permeable zone is not blocked; thirdly, the present invention minimizes the impact on the environment and has a beneficial environment-friendly effect; and finally, the sealing zone is printable with patterns or is provided with shapes such that the friendliness to end consumers is greatly improved and the product is no longer monotonous, and the bag body can be of any shape to meet the needs of different consumers.

A refrigerating and freezing device comprises a box body, a modified atmosphere film assembly and a suction pump. The box body has an inner container, a casing and a heat insulation layer; the inner container is internally provided with a storage space; the modified atmosphere film assembly is configured in such a way that more oxygen, relative to nitrogen, of a gas flow in a space around the modified atmosphere film assembly penetrates a modified atmosphere film and enters a rich-oxygen gas collecting cavity; and the suction pump is provided in the heat insulation layer, and an inlet end of the air extracting pump, through a pipeline, is in communication with the oxygen-rich gas collecting cavity of the modified atmosphere film assembly to pump and discharge the gas penetrated into the oxygen-rich gas collecting cavity out of a storage container.

A method for recovering hydrogen which is capable of efficiently recovering high concentration hydrogen gas by adsorbing and removing hydrocarbon gas such as carbon dioxide from biomass pyrolysis gas under a relatively low pressure, and also capable of storing the recovered high concentration hydrogen gas, preferably, in a cartridge type container that can be used as is as a hydrogen storing container for an apparatus equipped with a fuel cell. The method includes a first purifying stare of purifying biomass pyrolysis gas and a second purifying stage of purifying the obtained purified gas under a pressure equal to or less than the pressure in the first purifying stage to recover gas that contains hydrogen, and further includes a hydrogen storing stage of feeding the gas containing hydrogen recovered in the second purifying stage into the container filled with a hydrogen storage alloy and storing high purity hydrogen.

High-capacity dispensable moisture and hydrogen getter to be used as sealant and/or to control the level of these substances in electronic or optoelectronic sensitive devices, its use for the hermetic sealing or semi-hermetic sealing of such electronic or optoelectronic sensitive devices and a method to control the level of contaminants within them.

Systems for atmospheric water generation are disclosed. An illustrative system may comprise an atmospheric water generator, and a wireless communications device communicatively coupled to the atmospheric water generator. The wireless communications device may be configured to receive and display status information associated with the atmospheric water generator, and to provide operating instructions to the atmospheric water generator. The wireless communications device may be further configured to display an outside temperature, an outdoor humidity, a water level, an indoor temperature, an indoor humidity, and a dew point. The wireless communications device may be further configured to receive control instructions, and wherein the wireless communications device is further configured to communicate the control instructions to the atmospheric water generator.

A compressed air drying system is provided for removing moisture from compressed air. The system includes multiple air dryers that each remove moisture from a portion of the compressed air. The air dryers share a reservoir of liquid coolant that is used to cool the compressed air in each of the drying units. The reservoir has inlets for each of the drying units for the liquid coolant to return from the respective unit to the reservoir. The inlets are arranged in the reservoir to mix the incoming liquid coolant from the inlets to ensure that warm coolant from one of the inlets does not flow directly to an outlet of the reservoir.

The present invention describes the process of preparing ceramic materials for absorption of acidic gases, mainly carbon dioxide, in exhaust systems and/or present indoors. Ceramic materials are formed by a mixture of alkali carbonate with alkaline earth metal oxide/hydroxide associated with a binding component, but non-limiting. The alkali carbonate comprises sodium, potassium carbonate, or a mixture of both. The alkaline earth metal oxide/hydroxide may be formed from magnesium oxide or magnesium hydroxide as well as calcium oxide and/or calcium hydroxide.

A refrigerator comprises a refrigerator body, an air-conditioning membrane assembly and an air pump assembly. The refrigerator body defines a storage space and a compressor chamber therein, a storage container is arranged in the storage space, and a freshness-keeping space is defined inside the storage container. The air-conditioning membrane assembly is configured to allow more oxygen than nitrogen in airflow in a surrounding space of the air-conditioning membrane assembly to pass through the air-conditioning membrane and enter an oxygen-rich gas collection chamber. An inlet end of the air pump is communicated with the oxygen-rich gas collection chamber in a controlled manner via a pipeline and a pipeline switching mechanism, for pumping gas in the oxygen-rich gas collection chamber to the outside of the freshness-keeping space, such that the actual content of oxygen in the freshness-keeping space is in a range of 2% to 19%.

A tablet having a deliquescent desiccant and a fragrance encapsulated on or within a binding agent. The tablet is in a pressed form. A method of making a tablet involves providing a deliquescent desiccant, encapsulating a fragrance by spray drying the fragrance on a carbohydrate, combining the deliquescent desiccant and the carbohydrate encapsulated fragrance, and pressing the combination into the tablet.
