An upright vacuum cleaner is provided. Thanks to a mini nozzle seat formed by subsiding in a front side on an upper portion of the vacuum cleaner, a mini nozzle can be received in a stable and solid manner when the mini nozzle is not in use, whereby convenience in use can be enhanced.

Mechanisms are provided for automatically removing tips from a pipette nozzle and / or for detecting the type of tip mounted to the nozzle. For detipping, mechanical energy is stored when the tip is mounted to the nozzle and is released when the tip is to be removed to facilitate removal thereof. A mechanism is preferably provided which limits the force with which the tip is mounted to the nozzle and an overforce mechanism may be provided to facilitate removal of a stuck tip. For detecting tip type, each tip type has a different base configuration which results in a different relative displacement between the nozzle and a surrounding component as a result of the tip contacting both during tip mounting, the difference in relative displacement being detected to identify tip type.

The invention discloses the electrotome handle, lighting electrotome handle, vacuum suction tube, vacuum pump of an attraction electrotome. In the hollow electrotome handle, a power circuit of the electrotome is arranged in the electrotome handle or the wall of the electrotome handle; an attraction opening is formed the tail of the electrotome handle; a conducting blank pipe is provided with a hollow channel, and the rear end of the conducting blank pipe is arranged in the front of the electrotome handle; and the rear end of the conducting blank pipe is connected with the power circuit of theelectrotome, and the front end of the conducting blank pipe extrudes out of the electrotome handle and forms a thin tip suction inlet forward. The electrotome provided by the invention absorbs smoke generated in the process of operation uninterruptedly, and during the operation on a narrow and deep area, the electrotome can penetrate into the area to absorb the generated smoke, liquid impurities and the like close to the electrotome completely in time and discharge the smoke, the liquid impurities and the like to the outside or a sterilizer without blocking the negative pressure suction pipe and the negative pressure pump; and in an operation area of a narrow dark area, an illuminating lamp on the electrotome can also illuminate conveniently and clearly. In addition, an electrotome head, the electrotome handle and the negative pressure pump can be disassembled conveniently and quickly to be replaced and disinfected, and a filter screen and a filter can be replaced conveniently.

Provided is a suction device for a vacuum cleaner having a small-size nozzle with superior attachment / detachment performance and to provide a vacuum cleaner.This suction device is provided with the small-size nozzle 11 having a suction head 10 which is formed with a tip suction port 18, a small-size nozzle storage recess 16 detachably storing the small-size nozzle 11, and a floor nozzle 12 provided in the small-size nozzle storage recess 16 and having a projection part 23. When the small-size nozzle 11 is stored in the small-size nozzle storage recess 16, the projection part 23 is inserted in the tip suction port 18, so that the tip suction port 18 of the small-size nozzle 11 is guided by the projection part 23 and surely installed therein.

Contemplated within the scope of the invention are Yankauer suction systems having clog removal functionality and related methods. Specifically, the system, for use with a Yankauer suction tip, includes a medial tube that is hollow and has a coupling end and a distal outlet. The coupling end is connectable to a Yankauer suction tip and the distal outlet is in fluid communication with each of a flow pump and a suction source. Also included are systems having a medial tube that is hollow and comprises a coupling end, wherein the coupling end is connectable to a Yankauer suction tip; a suction conduit that extends distally from the medial tube to a suction source, wherein the suction conduit is in fluid communication with the suction source and the coupling end; and a flow conduit that extends distally from the medial tube and is in fluid communication with a flow pump and the coupling end.

The invention relates to a suction pen with double suction heads, which comprises a first airbag and a second airbag which are independent of each other, a first suction cup and a second suction cup which are mutually independent and arranged at intervals, a first air duct and a second air duct which are independent of each other, Both the first airbag and the second airbag are made of elastic materials, and can generate negative pressure under the action of elastic recovery after being squeezed; the first suction cup is used to absorb the first workpiece, and the second suction cup is used to absorb the second workpiece. The second workpiece is located on the first workpiece; the first air duct is used to communicate with the first air bag and the first suction cup, and the second air duct is used to communicate with the second air bag and the second suction cup. For the double-head suction pen of the present invention, when the second suction cup breaks the vacuum due to reasons such as the suction position or the shape of the second workpiece, it will not affect the vacuum adsorption of the first suction cup to the first workpiece, and because the second workpiece is located at the first On a workpiece, the double-ended suction pen of the present invention greatly reduces the probability of the workpiece falling.

The invention relates to a method for adhesion of film and an apparatus thereof, wherein flake film of the same size of adhesive substrate adhere to the substrate.Above the substrate 2, the film 1 isslanted, sucked, and held on the opposite surface side to a protective film 7 by a suction plate 33 and a tip suction plate 34. An adhesive tape 55 is stuck on the protective film 7, and the adhesivetape 55 is moved reversely at the tip of the film 1 to peel the tip of the protective film 7. A tip suction plate 34 is made to recede from the tip of the film. The tip of the film which peeled the tip of the protective film is joined to the tip of the substrate 2, and they are pressed by a press roller 46. The suction / holding of the film by the suction plate 33 is released. While the substrate 2is moved with the tip side of the film 1 made a head, the protective film 7 is peeled by the movement of the adhesive tape 55, the film 1 is supplied to the substrate 2, and the film 1 is stuck on thesubstrate 2 by the press roller 46. According to the invention, the delicate and complicated control of the adsorption and retention capacity is unnecessary, and it is simple and reliable that the film adheres to the substrate without dropping the film on the substrate.
