Pressure equalizing device for dental cleaning equipment

Abstract

The invention belongs to the technical field of medical appliance manufacture, and discloses a pressure equalizing device for dental cleaning equipment, the pressure equalizing device includes a water supply port 11, an upper cover 18, a pressure equalizing tube, a pressure equalizing plate 13 and a water supply pipe 14, the water supply port 11 is connected with a pressure equalizing casing 23, the pressure equalizing tube 12, the pressure equalizing plate 13 and the water supply pipe 14 are arranged in the pressure equalizing casing 23, a cavity formed by the pressure equalizing casing 23 and the upper cover 18 is divided into a first-stage pressure equalizing chamber 22 and a second-stage pressure equalizing chamber 20 by the pressure equalizing plate 13, the pressure equalizing tube 12 is communicated with the first-stage pressure equalizing chamber 22 by a plurality of flow guiding ports 21 arranged at the bottom of the first-stage pressure equalizing chamber 22, the apertures of the flow guiding ports 21 are different in size, the aperture of the flow guiding port nearest to the water supply port 11 is smallest, the apertures of the flow guiding ports are in turn increased, and with the aid of fluid characteristics, water supply pressure at the water supply port and the end of the pressure equalizing tube can be effectively reduced, and the physical pressure equalizing of a cleaning fluid can be realized.

Description

technical field [0001] The invention relates to the technical field of medical device manufacturing, in particular to a pressure equalizing device for dental cleaning equipment. Background technique [0002] In recent years, oral health has attracted more and more attention, and the use of dental handpieces has been increasing. At present, the cleaning of dental handpieces generally uses a spray washer-disinfector. Cleaning is carried out on the cleaning equipment, but this cleaning will cause poor cleaning effect on various parts of the dental handpiece due to the spray cleaning device. For example, the automatic three-dimensional cleaning of the dental handpiece cannot be realized. Inconsistencies in the spraying intensity of the parts cause problems such as incomplete cleaning or waste of resources. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a pressure equalization device for dental cleani...
