The broadband switched capacitor CMOS circulator comprises a switched capacitor network structure with N paths of same branches, a switch group on each side is controlled by a non-overlapping square wave modulation signal, and an inductor L is arranged on each side of the switched capacitor network structure; a group of switches are arranged at a central capacitor node of a switched capacitor network structure to form a three-port circulator, each layer of switch of the three-port circulator is controlled in a rotating mode, a central capacitor of each layer is charged from one port, and then charges are released to the next port; when the central capacitor of the first layer discharges through the port 3, the central capacitor of the second layer discharges through the port 2; a part of the discharge current of the second-layer center capacitor is fed into the first-layer center capacitor through the transformer in a reverse-phase mode, and the isolation degree from the first port to the third port is improved. The isolation degree and the working bandwidth can be improved, and the noise coefficient, the circuit complexity and the chip power consumption can be reduced.

This invention belongs to the field of end-face sealing technology, specifically relating to a combined corrugated groove end-face sealing device consisting of a rotating ring and a stationary ring. The invention includes a rotating ring and a stationary ring that cooperate with each other through sealing end faces. The sealing end faces are respectively provided with corrugated grooves and notched grooves. The ring containing the corrugated groove is a wide ring, and the ring containing the notched groove is a narrow ring. The sealing end face width of the wide ring is greater than that of the narrow ring, and the notched groove is located on the outer ring surface of the narrow ring. The rotation path of the corrugated groove intersects with the cavity of the notched groove. This invention achieves an effective balance between sealing leakage and end-face lubrication, thereby providing continuous and effective lubrication and cooling for the friction pair of the end-face seal.

The utility model provides a soft rubber panel for a remote control device and the remote control device, and belongs to the technical field of structural parts of electric equipment. The remote control device comprises an elastic sheet type instantaneous switch, hard rubber keys and an installation limiting structure for installing and limiting the hard rubber keys, the installation limiting structure is a soft rubber panel, the soft rubber panel comprises force transmission parts in one-to-one correspondence with triggering parts of the elastic sheet type instantaneous switch, the force transmission parts are in contact with the hard rubber keys, and the hard rubber keys are arranged on the elastic sheet type instantaneous switch. Mounting grooves in one-to-one correspondence with the hard rubber keys are formed in the soft rubber panel, blocking edges are arranged on the edges of the hard rubber keys, limiting flanges in blocking fit with the blocking edges are arranged at notches of the mounting grooves, and moving spaces for the hard rubber keys to move are formed in the mounting grooves. According to the utility model, the soft rubber panel is adopted to replace an installation limiting structure in the prior art, and the installation and the limiting of the hard rubber key can be realized only by assembling the hard rubber key and the soft rubber panel during assembly, so that the assembly is convenient. And the hard rubber keys are convenient to replace, so that the appearance configuration of each remote control device can be changed at the lowest cost.

The application belongs to the technical field of electric heating sucking device structure, and particularly relates to an independent automatic oil guiding electronic atomizer, which comprises an oil storage bin, a mounting seat, an atomization assembly and a smoke outlet pipeline. The oil storage bin comprises a shell which is provided with an oil guiding hole. One end of the shell is sealed by sealing elastic silica gel. The sealing elastic silica gel is provided with a weak part corresponding to the oil guiding hole. The atomization assembly is provided with a sealing column corresponding to the weak part. The sealing column is used for breaking the weak part when the oil storage bin is lowered, so that the oil storage bin is connected with the atomization assembly, and the normal use of the electronic atomizer is ensured. In actual application, the oil storage bin is an independent part, the sealing elastic silica gel ensures the sealing property of the oil storage bin, transportation is facilitated, and safety is improved. In use, the communication between the oil storage bin and the atomization assembly can be completed by only pressing the oil storage bin, automatic oil guiding is realized, and the operation is simple and convenient.
