Referring to fig. 1-2, a heat shield 5 is disposed in the liquid containing assembly 1, in this embodiment, a first connection portion 511 is disposed at the top of the heat shield 5, and the first connection portion 511 is detachably connected to the bottom of the head assembly 2, so that, after a period of use, the heat shield 5 can be detached from the bottom of the head assembly 2, thereby facilitating cleaning of the heat shield 5 and the heating assembly 3, and avoiding bacteria breeding. When the heat shield 5 is installed on the liquid containing assembly 1, the liquid storage space in the liquid containing assembly 1 is divided into a first space 11 positioned in the heat shield 5 and a second space 12 positioned outside the heat shield 5, and the heating assembly 3 is positioned in the first space 11; a first flow channel (not shown in the figure) for the liquid flowing from the first space 11 to the second space 12 is provided between the first space 11 and the second space 12, and as a preferred option, a through hole may be provided at the bottom of the heat shield 5 to connect the first space 11 and the second space 12, and of course, a communicating structure may also be provided on the liquid containing assembly 1, which may be specifically set as needed, and will not be described herein. The heat shield 5 is arranged in the liquid containing component 1, so that the heating component 3 does not need to heat all liquid in the liquid containing component 1, only the liquid in the first space 11 needs to be heated, the heating efficiency is improved, the outside can be humidified in a shorter time when a user just starts up for use, and the using effect of the humidifier is improved.

Based on this, referring to fig. 1, the heat shield 5 is of a hollow structure, the hollow structure is vacuumized to form a vacuum chamber 53, and the vacuum chamber 53 is disposed along the mist flowing direction. The vacuum cavity 53 is arranged on the heat shield 5, when noise propagates in the heat shield 5, the propagation of the noise along the side wall direction of the heat shield 5 is prevented by the vacuum cavity 53, so that the outward propagation of the noise along the heat shield 5 and the liquid containing assembly 1 is prevented, and the noise reduction effect of the humidifier is improved. In addition, the vacuum chamber 53 can perform a heat insulating function for the liquid in the first space 11 and the second space 12, thereby reducing heat loss of the liquid in the first space 11 and further improving heating efficiency of the liquid in the first space 11.

In addition, the bottom end of the upper heat shield 51 extends to the upper end of the heat conducting member 33, that is, the top end of the lower heat shield 52 is higher than the upper end of the heat conducting member 33, so that the lower heat shield 52 can fix the first noise reduction member 6, and the first noise reduction member 6 is tightly attached to the heat conducting member 33 to reduce noise (which will be described below), and in addition, when the heat conducting member 33 needs to be cleaned, the heat conducting member 33 can be exposed only by detaching the lower heat shield 52, and the upper heat shield 51 does not need to be detached, so that the problem of unstable connection between the heat shield 5 and the handpiece assembly 2 caused by detaching the whole heat shield 5 for multiple times is avoided.

Example 2

The embodiment provides a vacuum noise reduction type heating humidifier. Most of the structure of the humidifier is the same as that of embodiment 1, and the same structure is not described in detail, and the differences are specifically described below.

Referring to fig. 3, a first noise reduction member 6 located below the liquid level is fixedly connected in the lower heat shield, the first noise reduction member 6 is in a U shape, the arc surface of the U shape is coated and attached to the surface of the heat conduction member 33, and a fog outlet hole through which air bubbles penetrate is formed in the first noise reduction member 6. When the humidifier is in an operating state, the temperature of the heat conducting member 33 is transferred to the first noise reducing member 6, so that the liquid adsorbed by the first noise reducing member 68 is heated, and smaller bubbles are generated after the liquid is heated, so that large bubbles generated on the surface of the heat conducting member 33 are avoided from the source, and the noise reducing effect is ensured. In addition, the first noise reduction piece 6 also has the noise reduction effect, and noise reduction is achieved from the source, so that the noise reduction effect of the humidifier is guaranteed.

The first noise reduction member 6 is fixed in the lower heat shield 52, which may be fixed by a tie, or by other conventional fixing means, which will not be described in detail herein. The first noise reduction piece 6 is fixed in the lower heat shield 52, so that the first noise reduction piece 6 can be stably connected, the first noise reduction piece 6 can be stably wrapped on the surface of the heat conduction piece 33, meanwhile, when the first noise reduction piece 6 needs to be disassembled and replaced, the lower heat shield 52 can be directly disassembled from the upper heat shield 51, the first noise reduction piece 6 is disassembled, the whole heat shield is not disassembled, and the first noise reduction piece 6 is disassembled again, so that the disassembly is simple and convenient for a user to use. Of course, the first noise reduction member 6 with a density smaller than that of the liquid may be selected, the shape of the U-shaped arc surface of the first noise reduction member 6 is adapted to the surface shape of the heat conducting member 33, the size of the arc surface is slightly smaller than that of the heat conducting member 33, the outer wall of the first noise reduction member 6 is tightly attached to the inner wall of the lower heat insulating cover 52, and when assembled, the first noise reduction member 6 is tightly sleeved on the surface of the heat conducting member 33, and the outer wall of the first noise reduction member is tightly attached to the inner wall of the lower heat insulating cover 52, so that the connection between the first noise reduction member 6 and the heat conducting member 33 is realized. When the liquid containing component 1 contains liquid, under the action of the buoyancy of the liquid, the first noise reduction piece 6 floats upwards, so that the first noise reduction piece 6 is more firmly sleeved on the surface of the heat conduction piece 33, and the stability of connection is ensured.

Referring to fig. 4, the second noise reduction member 7 is provided in the mist outlet passage 4, and includes an integrated immersion portion 71 and an exposed portion 72 provided above the immersion portion 71, the immersion portion 71 being located below the liquid surface L1 of the liquid, and the exposed portion 72 being located above the liquid surface L1 of the liquid. The second noise reduction member 7 is provided with a fog outlet (not shown in the figure) through which the air bubbles pass. When in use, the second noise reduction piece 7 is installed in the liquid containing assembly 1, the immersion part 71 of the second noise reduction piece 7 is positioned below the liquid, the exposure part 72 of the second noise reduction piece 7 is positioned above the liquid, when large bubbles generated by the heating assembly 3 or large bubbles formed by fusion of the bubbles in the rising process reach the bottom surface of the immersion part 71, the bubbles are divided into tiny bubbles, the tiny bubbles pass through the immersion part 71, and then burst in the process of penetrating out of the exposure part 72. Compared with the explosion of big bubbles, the explosion of small bubbles produces less noise, so that the larger noise caused by the explosion of big bubbles is avoided, and the noise is effectively reduced. In addition, the noise generated by the small bubbles in the blasting process is partially absorbed and counteracted by the second noise reduction piece 7, so that the noise reduction effect of the humidifier is further improved.

Wherein the immersion part 71 is suspended in the liquid, i.e. the entire second noise reduction member 7 floats on the liquid. When the humidifier is used, the liquid level of liquid can drop in the working process of the humidifier, and at the moment, the second noise reduction piece 7 moves downwards along with the drop of the liquid level, so that the humidifier is simple in structure, meanwhile, the problem that the liquid level is separated from the immersion part 71 due to the drop of the liquid level is skillfully avoided, the second noise reduction piece 7 cannot reduce noise on bubbles at the liquid level, and the noise reduction effect at the liquid level is guaranteed. It will be appreciated that the outer side wall of the second noise reduction member 7 is not in contact with other side walls, such as the inner wall of the heat shield, and there is a first distance, and the first distance not only enables the second noise reduction member 7 to slide smoothly up and down, but also enables large bubbles to burst into small bubbles within the first distance, so as to avoid noise caused by large bubble burst.

Referring to fig. 4, the middle position of the second noise reduction member 7 is provided with a hole structure so as to be slidably sleeved on the first bracket 31, when the liquid level of the liquid rises or falls, the second noise reduction member 7 moves up and down along the first bracket 31, the first bracket 31 not only guides the second noise reduction member 7 to move up and down, but also assist the first bracket 31 in fixing the second noise reduction member 7 to float on the liquid level of the liquid, so that the second noise reduction member 7 is prevented from rolling.

Referring to fig. 1, 3 or 4, the heat conducting member 33 includes a side heat conducting section 331, an end heat conducting section 332, and a transition section 333 connecting the side heat conducting section 331 and the end heat conducting section 332, the cross-sectional shape of the side heat conducting section 331 and/or the transition section 333 is arc-shaped, in this embodiment, the cross-sectional shape of the side heat conducting section 331 and the transition section 333 is arc-shaped, and the end heat conducting section 332 is a plane. By setting the cross-sectional shapes of the side heat conducting sections 331 and the transition sections 333 to be arc-shaped, when the heating component 3 heats, the distance between the bubbles on the surface of the arc-shaped heat conducting piece 33 is larger than the distance between the bubbles on the surface of the plane heat conducting piece 33, and the bubbles are not easy to fuse on the surface of the arc-shaped heat conducting piece 33, so that the problem that large noise is caused due to large bubbles generated on the surface of the heat conducting piece 33 is effectively solved.

In other alternative embodiments, the heat conducting member 33 is in a spherical or oblate spherical shape, and of course, other spherical (cambered surface) structures are also possible, so that the heat conducting member 33 has no plane, and the problem of bubble fusion on the surface is the lowest. Further, the arc-shaped cross sections of the upper side heat conduction section 331 and the transition section 333 are convex arc-shaped, and of course, they may be concave arc-shaped, and convex arc-shaped is preferable in this embodiment. The convex arc and the concave arc can both relieve the problem that bubbles are fused into large bubbles on the surface of the heat conducting piece, and the difference is that after the small bubbles leave the surface of the heat conducting piece 33 with the section of the concave arc, the small bubbles rise in an aggregated state, and the small bubbles are easy to fuse to form large bubbles; and after the small bubbles leave the surface of the heat conducting piece 33 with the cross section being in the convex arc shape, the small bubbles rise in a diffused state, and the small bubbles are dispersed and are not easy to fuse, so that the problem that large bubbles are fused in the rising process of the bubbles and large noise is caused is effectively solved.

In order to further reduce the problem of fusion of bubbles during the rising process, in this embodiment, the outline of the end of the side heat conduction segment 331 far away from the end heat conduction segment 332 is circular, the outline of the end of the side heat conduction segment far away from the end heat conduction segment is circular on the section passing through the circle center of the circle, the chord length AB corresponding to the arc is between 15 and 180mm on the section passing through the circle center of the circle, and the distance from the circle center to the side heat conduction segment or the end heat conduction segment is between 16 and 200mm. Based on this, when the small air bubbles leave the surface of the heat conducting member 33, the small air bubbles are diffused in different directions, so that the air bubbles are uniformly raised in all directions (compared with the air bubbles generated by the heat conducting member 33 with the convex arc-shaped cross section, the air bubbles are more dispersed and uniform), and the problem that the large air bubbles are fused into large air bubbles in the raising process of the small air bubbles, so that large noise is caused is further alleviated.

The heat conducting piece 33 with the convex arc-shaped cross section and the heat conducting piece 33 with the specific arc length and size relationship are arranged above, and small bubbles generated by the heat conducting piece 33 reach the bottom of the immersion part 71 of the second noise reduction piece 7, then part of the small bubbles directly pass through the mist outlet holes of the small bubbles and then burst, and part of the small bubbles burst at the bottom of the immersion part 71 and are divided into smaller air holes so as to pass through the mist outlet holes. Because the bubbles are smaller and distributed uniformly, after the bubbles burst, the immersion part 71 of the second noise reduction piece 7 is suspended in the liquid, and the noise reduction effect of the second noise reduction piece 7 is basically not affected, so that the immersion part 71 is effectively prevented from exposing to the liquid surface due to the burst of the large bubbles at the bottom of the immersion part 71, the noise reduction effect of the second noise reduction piece 7 is reduced, or the immersion part 71 is exposed to the liquid surface due to the concentrated burst of the bubbles at a certain position at the bottom of the immersion part 71, and the noise reduction effect of the second noise reduction piece 7 is reduced.
