Abstract: A funnel storage device is provided, wherein the funnel storage device includes: a tubular member including a first end portion and a second end portion; a receiving member connected to the first end portion, in communication with an interior of the tubular member, and tapering in a direction toward the first end portion; and a base connected to the second end portion, not in communication with the interior of the tubular member, and expanding in a direction away from the second end portion.

Abstract: A fluid filling device is provided, including: a covering unit, a quick-connecting unit and a base. The covering unit is configured to cover an opening portion. The covering unit includes a first flow channel, and the first flow channel is configured to be communicated with an interior of the opening portion. The quick-connecting unit is disposed on the covering unit and communicated with the first flow channel. The base includes at least one joint, a second flow channel and a connection portion. The at least one joint is configured to be assembled with at least one pipe. The second flow channel is communicated respectively with the at least one joint and the connection portion. The connection portion is detachably and communicatedly connected with the quick-connecting unit.

Abstract: An oil filling device is provided, including: a main body, configured to cover an open end portion of an oil pot, including at least one first sliding portion and a channel; a control member, rotatably disposed on the main body; two clamping members, at least one of the two clamping members including a second sliding portion slidably mounted to the at least one first sliding portion; at least one guiding unit, each of the at least one guiding unit including a guiding groove and an assembly portion; at least one positioning member, connected to the assembly portion and slidably disposed within the guiding groove, wherein rotation of the control member operates to control at least one of the two clamping members to move relative to the main body so that the two clamping members relatively approach to or distance away from each other.
