The present application provides an ejector, a processing device, and a cleaning device, which can suppress a decrease in suction force in a case where liquid intrudes into the inside of the ejector and inexpensively perform processing or cleaning of an object to be processed. The ejector generates a suction force, the ejector having: an inflow pipe having a plurality of openings formed at a front end thereof from which a drive fluid is ejected; an outflow pipe having a receiving port that receives the drive fluid ejected from the openings at a position opposite to the front end of the inflow pipe; and a main body portion that surrounds around the openings and the receiving port, having a suction passage that suctions an external fluid to the inside.

This utility model provides a multi-channel urinary system stone removal device, which includes an insertion part and an operating part. The insertion part is continuously provided with a front end, a bending part and a tube body from the distal to the proximal side. The front end of the insertion part is provided with a camera element for imaging the cavity. The insertion part is provided with at least one first tube and at least one second tube. The first tube is used to deliver liquid or energy device into the human body, and the second tube is used to expel liquid from the body. The operating part is located at the base end of the insertion part. The operating part includes a gripping part, a bending operating part, a first connector and a second connector. The gripping part is for the user to hold and use. The first connector is connected to the first tube, and the second connector is connected to the second tube. The first connector is suitable for connection with an external irrigation device, and the second connector is suitable for connection with a negative pressure suction device.

The application provides a virtual resource pushing method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: obtaining a current geographical text message initiated by a user of a virtual resource to be pushed; obtaining a target geographical text information set matched with the current geographical text message based on query keyword information and current position information issued by the user for describing the virtual resource contained in the current geographical text message; updating the target geographical text information set by using the message; obtaining a virtual resource set matched with the updated target geographical text information set; and pushing the virtual resource contained in the virtual resource set to a target user issuing information in the target geographical text information set. The method can consider regional influencing factors, improve the timeliness of virtual resource pushing, and mine potential users.

The application relates to a device for attracting fish and continuously circulating and lifting fish in a ring-shaped track, and relates to the technical field of fish passing through a high dam of a hydropower station. The device comprises a fish-attracting channel, a fish deflecting weir and a fish lifting assembly. The fish-attracting channel is located downstream of the high dam. The fish deflecting weir is arranged in the fish-attracting channel. The fish lifting assembly comprises fish conveying boxes, a track and a power unit. The track is arranged on the high dam and downstream of the high dam, the track is ring-shaped and extends downwards along the high dam to the fish-attracting channel, at least two fish conveying boxes are arranged and used for conveying fish entering the fish-attracting channel, each fish conveying box is hung below the track, and the power unit is used for driving the fish conveying boxes to move along the track. The device has the effects of continuously circulating and lifting fish and improving the fish passing efficiency.
