This application provides a decorative member, a housing assembly, and an electronic device. In the decorative member, a plurality of balance holes and balance valves covering the balance holes are arranged on a support, including at least two first balance holes arranged at intervals on a main board portion of the support and first balance valves covering the first balance holes. In addition, a plurality of vent channels in communication with each other are formed in a region on the main board portion where a first adhesive layer is not arranged, and an end of each of the vent channels extends to an edge of the main board portion and is in communication with a first vent gap formed between a cover plate and a decorative ring.

A valve includes: (i) a valve seat; (ii) a guide assembly including a check portion, the guide assembly being configured to move between a first closed position where the check portion contacts the valve seat and a first open position where the check portion is spaced apart from the valve seat; (iii) a plurality of guides that are sized and configured to contact an outer perimeter of the guide assembly to axially align the guide assembly at least when (a) the guide assembly is in the first closed position and (b) the guide assembly is in the first open position; (iv) a plurality of channels, each of the plurality of channels being located between at least two of the plurality of guides.

An electronic cigarette vaporizer system including a cartridge designed to provide a liquid or other substance for the electronic vaporizer system, the cartridge including a chip that stores data related to the batch number of the substance stored in the cartridge, and the cartridge being adapted to be inserted into or form an integral part of the electronic vaporizer system. The electronic vaporizer system reads the data from the chip and compares that data with stored data and, depending on the result of that comparison, either prevents or permits use of that substance.

A flushometer system having an integrated control stop and three ports. The piston or flush control device is accessible through an actuation opening. The flushometer system may be utilized in a behind-the-wall installation with a face plate exterior for user interaction. The interior of the flushometer may be accessed through the actuation opening behind the face plate.

A shutoff vent is disclosed. A main body has a first end and a second end. The main body defines a first opening towards the first end, a second opening towards the second end, and a mating port between the first opening and the second opening. The first opening and the second opening are in communication through the mating port to define a gas passageway. A translatable plug is disposed within the main body, and the gas passageway extends past the translatable plug. The translatable plug is configured to reversibly translate towards the second end to sealably obstruct the mating port. In some examples, the translatable plug is configured to translate towards the second end when force is applied to the translatable plug from the first end.

An electronic cigarette vaporizer is not dis-assembled for filling with e-liquid, but is instead filled from a user-replaceable e-liquid cartridge. The vaporizer includes a front section comprising a wick and heating assembly but no e-liquid cartridge, the front section being removably fitted to a body of the vaporizer to enable a replacement front section to be used once the original wick or heating element starts to degrade, that replacement front section being supplied to the end-user with no e-liquid in it.

The invention is an electronic cigarette vaporizer system operable in a discrete mode to reduce the amount of vapor produced by a vaporizer that forms part of the system, compared to a normal mode. The discrete mode causes the vapor produced to be less visible or noticeable, compared to a normal mode.

An electronic cigarette vaporizer that includes a heating element and further includes or co-operates with an electronics module that (i) detects characteristics of the delivery of power, current or voltage to the heating element and (ii) determines if those characteristics are associated with degradation of the heating element. A characteristic that is associated with degradation of the heating element is an increase or other change in the heating element resistance. The heating element resistance can be established by the electronics module sending a test current through the heating element that is sufficient to enable a measurement of resistance to be made.
