摘要： The present invention relates to a dental water heater. The water heater has a columnar body, and the body includes heating means extending in the axial direction of the body, and a plurality of layers of water channel sections arranged around the heating means. Each of the water channel sections spirally extends in the axial direction of the body. The adjacent pairs of the water channel sections are communicated either at upper or lower end portions thereof so as to together form a whole water channel. The whole water channel has an inlet and an outlet for water to be heated, so that water is supplied through the inlet, passed through the entire length of the whole water channel, and taken out as warmed water through the outlet.

摘要： An exchangeable cartridge for a dental handpiece includes first dust-proofing members for preventing foreign matter from being intruded into an upper bearing and second dust-proofing members for preventing foreign matter from being intruded into a lower bearing. The first dust-proofing members have an upper rotational partitioning member and an upper fixed partitioning member. The upper rotational partitioning member has a protrusion provided above the upper bearing and protruding radially outwardly. The upper fixed partitioning member has a radially inwardly protruding portion lying adjacent and parallel to the protrusion of the upper rotational partitioning member to define a first interstice leading to the upper bearing. The second dust-proofing members have a lower rotational partitioning member and a lower fixed partitioning member. The lower rotational partitioning member has a protrusion provided below the lower bearing and protruding radially outwardly. The lower fixed partitioning member has a radially inwardly protruding portion lying adjacent and parallel to the protrusion of the lower rotational partitioning member to define a second interstice leading to the lower bearing.
