The humidifier has a reservoir 40 and an atomizer, the reservoir 40 being adapted to hold a liquid, such as water, to be atomized. The atomizer is disposed in the water to atomize the water, and for example, the atomizer may generate ultrasonic waves to atomize the water by high frequency oscillation. The mist is ejected along the spray opening through the humidifier, thereby increasing the ambient humidity.

In the embodiment of the present invention, as shown in fig. 1 to 4, the silencer includes: the outer silencing cover 10 is provided with a flow passage which is opened towards the top and the bottom; the inner silencing cover 20 is arranged in the overflowing channel, a water falling space 11 is formed between the inner silencing cover 20 and the overflowing channel, a fog inlet is formed at the bottom end of the inner silencing cover 20, a fog outlet 21 is formed at the top end of the inner silencing cover, a water retaining edge 22 extending along the circumferential direction is convexly arranged on the outer circumferential wall of the inner silencing cover 20, the outer circumferential edge of the water retaining edge 22 abuts against the inner circumferential wall of the outer silencing cover 10, and a water drainage hole 221 is formed in the outer circumferential edge of the water retaining edge 22.

In this embodiment, the outer muffling cover 10 is disposed in a cylindrical shape with openings at the upper and lower ends and covers the inner muffling cover 20, the muffler is disposed in the water tank 40 and above the atomizer, water columns and water mist during atomization will enter the flow passage from the bottom opening of the outer muffling cover 10, and the water mist will flow upward after flowing out from the top opening until flowing out of the atomizing nozzle. The water column and the water mist can pass through the mist inlet and the mist outlet 21 of the inner muffler cover 20 after entering the overflowing channel, then the water mist can continuously rise, and the water column can fall back under the action of gravity. The falling water column part enters the water falling space 11 between the inner muffling cover 20 and the outer muffling cover 10 and is caught by the water retaining rim 22 which blocks the water falling space 11. The water flows to the water discharge hole 221 after falling on the water blocking rim 22, and the water discharge hole 221 penetrates the periphery of the water blocking rim 22, so that the water flowing through the water discharge hole 221 adheres to the inner wall surface of the outer noise canceling cover 10, and flows down along the inner wall surface of the outer noise canceling cover 10 into the water tub 40.

The inner silencing cover 20 and the outer silencing cover 10 can be connected in a clamping mode or can be connected through a fastening piece, and the connection is not limited, and only the requirement that the inner silencing cover 20 and the outer silencing cover 10 can be relatively fixed is met. The water retaining edge 22 is annularly arranged, the water retaining edge 22 can be arranged in the middle of the inner silencing cover 20 or close to the bottom of the inner silencing cover 20, and the water retaining edge 22 is not limited herein and only needs to partition the water falling space 11; in practical application, the water retaining rim 22 is connected to the bottom end of the inner muffler cover 20 to shorten the distance from the water surface, so that the water received by the water retaining rim 22 can flow into the water tank 40 more quickly. The number of the drainage holes 221 may be one or more; in practical applications, the number of the drainage holes 221 is multiple, and the multiple drainage holes 221 are arranged at intervals along the circumferential direction of the water retaining rim 22 to improve drainage efficiency.

The utility model discloses the muffler can be installed above the atomizer in the humidifier, and the water smoke that the atomizer produced can flow to the fog nozzle of humidifier through fog outlet 21, and the water column that the atomizer arouses also can pass after fog outlet 21 and then fall simultaneously; the water retaining edge 22 is convexly arranged on the outer peripheral wall of the inner silencing cover 20, so that a water column passing through the mist outlet 21 enters the water falling space 11 and then is firstly received by the water retaining edge 22, then flows to the water discharging hole 221 adjacent to the outer silencing cover 10, and finally flows back to the water tank 40 along the inner peripheral wall of the outer silencing cover 10, therefore, the kinetic energy of the water falling back to the water tank 40 can be reduced, the impact of the water falling on the water surface is weakened, the noise generated by the humidifier is reduced, and the user experience is improved.

As shown in fig. 2, the top surface of the water blocking edge 22 forms a diversion inclined surface 222, and the diversion inclined surface 222 inclines downward in a direction from the inner muffling cover 20 to the outer muffling cover 10. The diversion inclined plane 222 is a plane for receiving water, and the diversion inclined plane 222 can be formed by the water retaining edge 22 itself in an inclined manner, so that the structure of the water retaining edge 22 is simplified, and the processing difficulty is reduced. Since the drainage hole 221 is located at a side of the water blocking edge 22 adjacent to the outer muffler shell 10, water falling to the water blocking edge 22 can flow to the drainage hole 221 more quickly and sufficiently under the action of the diversion slope 222, and the water is prevented from accumulating at the water blocking edge 22.

As shown in fig. 2, the inner noise canceling cover 20 is formed to be flared from the top toward the bottom so that the outer wall surface of the inner noise canceling cover 20 may be inclined upward. The water column excited by the atomizer can be dispersed all around and fall under the inertia effect, and the falling water can contact the outer wall surface of the inner muffler cover 20 which is inclined upwards firstly and then flows to the water retaining edge 22 along the outer wall surface, so that the falling water can be prevented from directly impacting the water retaining edge 22 to generate noise, and the noise of the humidifier is further reduced. In practical application, the outer wall surface of the inner muffling cover 20 is further convexly provided with the drainage ribs, and the drainage ribs extend along the axial direction of the inner muffling cover 20 so as to drain water falling on the outer wall surface of the inner muffling cover 20 to the water retaining edge 22, so that the backflow efficiency of the water is improved.

As shown in fig. 1 and 3, the inner muffler cover 20 has through holes 23 formed in a peripheral wall thereof to increase the amount of water mist passing therethrough and improve the spraying efficiency. The through hole 23 can extend along the axial direction of the inner muffler cover 20 to increase the flow area; the number of the through holes 23 may be plural, and the plural through holes 23 are provided at intervals in the circumferential direction to further increase the amount of the mist passing therethrough. In addition, the through hole 23 can avoid rising water columns, and the water columns can avoid impacting the inner wall surface of the inner sound attenuation cover 20, so that noise is further reduced. The rising height of the water column is gradually reduced from the middle to the periphery, and in combination with the embodiment in which the inner muffler cover 20 is formed in the shape of a flared opening, the water column with a lower height can more quickly contact the inclined outer wall surface of the inner muffler cover 20 after passing through the through hole 23, so that the time for acceleration in the air is reduced, and the impact on the inner muffler cover 20 is reduced.

As shown in fig. 1 and 3, a flow guiding rib 223 is protruded on a top surface of the water blocking edge 22, and the flow guiding rib 223 extends along an edge of the water discharge hole 221 close to the inner muffling cover 20 and is spaced from an inner circumferential wall of the outer muffling cover 10. The flow guiding rib 223 can prevent the water flow from falling from the side of the water discharge hole 221 away from the outer noise reduction cover 10, and can guide the water flow to the inner wall surface of the outer noise reduction cover 10, so as to ensure that the water can be left along the inner wall surface of the outer noise reduction cover 10, and thus, the sound of the water flow impacting the water surface can be effectively reduced.

As shown in fig. 2 and 5, the bottom end of the outer muffling cover 10 protrudes from the bottom end of the inner muffling cover 20 to extend the path of water flowing along the outer muffling cover 10, so that the water can enter the water more quickly after leaving the outer muffling cover 10. In practical application, the bottom end of the outer muffling cover 10 is immersed in the water, so that the water flowing along the outer muffling cover 10 can directly flow into the water, thereby further avoiding impacting the water surface and further reducing the noise of the humidifier.

As shown in fig. 1 and 2, the silencer further includes a buffer sheet 30 movably connected to the inner silencer casing 20, and the buffer sheet 30 is located above the fog outlet 21 and at least partially shields the fog outlet 21. The buffer sheet 30 can be integrally formed with the inner muffler cover 20 to reduce the processing difficulty. The buffer sheet 30 can be connected to the periphery of the mist outlet 21 and can be moved by thin-wall connection, so as to reduce the difficulty of connecting the buffer sheet 30 and the inner muffler cover 20. The buffer surface of the buffer sheet 30 is inclined downwards, the water column passing through the mist outlet 21 pushes the buffer sheet 30 open, and the rising height of the water column is reduced under the action of the buffer sheet 30 so as to shorten the falling time in the air, thereby weakening the impact on the inner silencing cover 20 and reducing the noise. The buffer sheet 30 is elastically restored to the original position under the action of the thin wall after being pushed open, so as to keep shielding the mist outlet 21, thereby preventing water columns passing through the mist outlet 21 from falling into the water tank 40 from the mist outlet 21, and flowing to the falling space after contacting the top surface of the buffer sheet 30, so that the impact between falling water and the water surface can be further reduced, and the noise can be further reduced.

As shown in fig. 1 and 4, the peripheral wall of the outer noise reduction cover 10 is opened with an air passing hole 12 communicating with the air passing passage. In the internal structure of the humidifier, a fan blowing air upward is provided below the water tank 40 to blow the mist toward the mist outlet more quickly. Because the top opening of the outer silencing cover 10 enters the fog outlet channel for connection, the airflow of the fan needs to enter the overflowing channel first to blow the fog, and the bottom opening of the outer silencing cover faces the water surface, namely the airflow cannot directly enter the overflowing channel from bottom to top. Therefore, the air holes 12 opened in the peripheral wall of the outer noise-reduction cover 10 allow the air flow to enter the air flow passage, thereby effectively blowing the mist. The air passing holes 12 can be close to the bottom end of the outer silencing cover 10, so that the air flow can contact more water mist after entering the air passing channel, and the blowing efficiency of the water mist is improved.

The outer muffling cover 10 is made of hard materials, such as hard plastics, so that the structural strength of the integral shell of the muffler is improved, and the outer muffling cover 10 can be fixedly connected with the structure in the humidifier to improve the installation stability of the muffler. The inner silencing cover 20 is made of soft materials, such as soft silica gel, so as to reduce noise generated when the inner silencing cover collides with water, and further improve user experience. The outer muffling cover 10 and the inner muffling cover 20 are made of two materials, respectively, so that the structural stability of the muffler can be improved, and the noise reduction effect can be improved.

In practical application, the inner wall surface of the outer muffling cover 10 is convexly provided with a lug, the lug is provided with a fixing hole, the top surface of the water retaining edge 22 is convexly provided with a fixing protrusion, and the fixing protrusion is matched with the fixing hole, so that the inner muffling cover 20 is fixed in the outer muffling cover 10, the water retaining edge 22 is effectively utilized, and the matching strength of the inner muffling cover 20 and the outer muffling cover 10 is improved.
