Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and more specifically, to a low-water-noise humidifier. Background Technology

[0002] Humidifiers are widely used appliances in homes. By increasing air humidity, humidifiers can alleviate discomfort caused by dry environments to the human body, such as respiratory and skin problems. However, humidifiers inevitably generate various noises during operation, such as the mechanical sound of the fan, the high-frequency vibration of the ultrasonic transducer, and the sound of water. These noises significantly impact the user experience. The water noise primarily originates from larger water droplets carried in the mist atomized by the ultrasonic transducer. As these droplets disperse with the mist to the humidifier's outlet, they condense or collide with the internal structure of the humidifier, falling vertically and randomly splashing onto the water surface, producing a noticeable impact sound.

[0003] Currently, in the humidifier industry, with technological advancements, existing noise-reducing humidifiers can control the mechanical noise of the fan and the high-frequency vibration of the ultrasonic transducer to low levels. Against this backdrop, the noticeable impact sound of larger water droplets splashing onto the water surface has become one of the main sources of noise during humidifier operation. Especially in quiet environments such as bedrooms and studies, the continuous splashing sound directly interferes with users' sleep, rest, or concentration. However, the noise reduction effect of existing humidifiers on water noise still does not meet the needs of quiet environments; therefore, how to provide a humidifier that more effectively reduces water noise has become an urgent problem to be solved.

[0004] The purpose of this invention is to provide a low-noise humidifier to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0006] This utility model provides a low-noise humidifier, including a housing and a mist outlet disposed on the top of the housing. The housing forms an inner cavity, which includes, from top to bottom, the following components: A water storage chamber for storing water; The mist outlet chamber is equipped with a water supply component, which cooperates with the water storage chamber to transfer water in the water storage chamber to the mist outlet chamber; The configuration space is equipped with an ultrasonic module that communicates with the mist outlet cavity; The mist outlet and the mist outlet cavity are provided with a mist guiding cavity. A water baffle is provided at one end of the mist guiding cavity near the mist outlet cavity. The water baffle includes an inner cavity that runs vertically through the middle and a side wall. A mist inlet is provided at one end of the inner cavity near the mist outlet cavity. The side wall of the water baffle is also provided with a through hole facing the configuration space. Furthermore, a water droplet slow-fall portion is provided on the outer side of the side wall of the water baffle located outside the through hole.

[0007] In some embodiments of this application, there are several through holes, and the several through holes are arranged circumferentially along the side wall of the water-blocking member; there is a radial gap between the through holes and the water droplet slow-fall portion. In some embodiments of this application, there are several water droplet slow-fall portions; the several water droplet slow-fall portions are arranged circumferentially along the side wall of the water-blocking member, and there is a horizontal gap between adjacent water droplet slow-fall portions; the horizontal gap is staggered from the longitudinal projection area of ​​the through hole; the water droplet slow-fall portion has an upper surface, and the upper surface extends obliquely upward from the end of the through hole near the mist inlet in a direction gradually away from the through hole.

[0008] In some embodiments of this application, the upper surface of the water droplet slow-fall portion is an arc-shaped upper surface that extends obliquely upward from one end of the through hole near the mist inlet and gradually away from the through hole; each water droplet slow-fall portion is a curved rib, and the longitudinal projection of the curved rib overlaps with the projection area of ​​the through hole.

[0009] In some embodiments of this application, the inner cavity of the water-blocking component narrows from top to bottom; the water-blocking component includes an upper section, a lower section, and a transition section, the upper section being detachably connected to the end of the mist guiding cavity near the mist outlet cavity; the inner diameter of the upper section is larger than the inner diameter of the lower section; the side wall of the transition section is provided with the through hole, and the outer side wall of the lower section is provided with the water droplet slow-fall portion.

[0010] In some embodiments of this application, at least two locking blocks are provided on the outer side wall of the upper section, and at least two locking slots are provided at the end of the mist guiding cavity near the mist outlet cavity, and the locking blocks are engaged with the locking slots.

[0011] Some embodiments of this application also include a fan, which is disposed within the configuration space and the air outlet of the fan is aligned with the mist guiding chamber; an air inlet is provided on the side wall of the upper section.

[0012] In some embodiments of this application, the water-blocking component is integrally formed.

[0013] In some embodiments of this application, the mist guiding cavity is a conical channel, and the cross-sectional area of ​​the end of the mist guiding cavity near the mist outlet is greater than the cross-sectional area of ​​the end of the mist guiding cavity near the mist outlet.

[0014] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects: This utility model discloses a low-noise humidifier. By setting a mist guiding chamber between the mist outlet and the mist outlet cavity, it not only guides the flow of water mist generated by the vibration of the ultrasonic module, but also ensures that the falling area of ​​large water droplets generated by condensation or collision in the water mist is limited to the projection area corresponding to the mist guiding chamber. A water baffle is set at one end of the mist guiding chamber near the mist outlet cavity. The side wall of the water baffle has a through hole facing the configuration space. The through hole is used to allow some water mist that does not enter the mist guiding chamber through the mist inlet to enter the mist guiding chamber. Furthermore, the outer side wall of the water baffle also has a water droplet slow-fall section located outside the through hole, so that water droplets in the water mist can form an attached flow along the water droplet slow-fall section and slide down to the water surface when falling. Preferably, the water droplet slow-fall section is a curved rib, and the longitudinal projection of the curved rib overlaps with the longitudinal projection area of ​​the through hole. Therefore, water droplets whose falling area is opposite to the radial gap between the through hole and the water droplet slow-fall section can slide smoothly down to the water surface along the curved rib. As a result, most water droplets slide off the water surface after being buffered by the water-blocking device during their fall, effectively preventing water droplets from splashing directly onto the water surface and thus significantly reducing the water noise generated by water droplets directly hitting the water surface.

[0022] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0023] Please see Figures 1 to 3 The low-noise humidifier provided in one embodiment of the present invention mainly includes a shell 10 and a mist outlet 20 disposed on the top of the shell 10. The shell 10 forms an inner cavity, which includes, from top to bottom, a water storage cavity 1, a mist outlet 2 and a configuration space 3.

[0024] The water storage chamber 1 is used to store water.

[0025] The mist outlet chamber 2 is equipped with a water supply component, which works in conjunction with the water storage chamber 1 to transfer water from the water storage chamber 1 to the mist outlet chamber 2.

[0026] The configuration space 3 is equipped with an ultrasonic module (not shown in the figure) that communicates with the mist outlet chamber 2.

[0027] A mist guiding chamber 4 is provided between the mist outlet 20 and the mist outlet cavity 2. A water-blocking component 5 is provided at one end of the mist guiding chamber 4 near the mist outlet cavity 2. The water-blocking component 5 includes an inner cavity that runs vertically through the middle and a side wall. The side wall of the water-blocking component 5 is provided with a through hole 521 facing the configuration space 3. A mist inlet 532 is provided at one end of the inner cavity near the mist outlet cavity 2. A water droplet slow-falling part 531 is also provided on the outer side of the side wall of the water-blocking component 5, located below the through hole 521.

[0028] This utility model discloses a low-noise humidifier. By setting a mist guiding chamber 4 between the mist outlet 20 and the mist outlet chamber 2, it not only guides the flow of water mist generated by the vibration of the ultrasonic module, but also ensures that the falling area of ​​large water droplets generated by condensation or collision in the water mist is limited to the projection area corresponding to the mist guiding chamber 4. A water baffle 5 is set at one end of the mist guiding chamber 4 near the mist outlet chamber 2. The side wall of the water baffle 5 has a through hole 521 facing the configuration space 3. The through hole 521 is used to allow some water mist that does not enter through the mist inlet 532 to enter the mist guiding chamber 4. Furthermore, the outer side wall of the water baffle 5 also has a water droplet slow-fall portion 531 located outside the through hole 521, so that water droplets in the water mist can form an attached flow along the water droplet slow-fall portion 531 and slide down to the water surface when falling. Thus, it effectively avoids water droplets splashing directly onto the water surface, thereby significantly reducing the water noise generated by water droplets directly hitting the water surface.

[0029] Please see Figure 3 In a preferred embodiment, there are several through holes 521, and the several through holes 521 are arranged circumferentially along the side wall of the water-blocking member 5; there is a radial gap between the through holes 521 and the water droplet slow-fall portion 531.

[0030] Please see Figure 1 and Figure 3 In a preferred embodiment, there are several water droplet slow-fall portions 531; these portions are arranged circumferentially along the sidewall of the water-blocking member 5, and there is a horizontal gap between adjacent water droplet slow-fall portions 531; the horizontal gap between the through hole 521 and the water droplet slow-fall portions 531 is staggered from the longitudinal projection area of ​​the through hole 521. The horizontal gap between the water droplet slow-fall portions 531 and the radial gap between the through hole 521 and the water droplet slow-fall portions 531 allow the water mist generated by the mist outlet chamber 2 to rise to the through hole 521 and enter the mist guiding chamber 4.

[0031] Meanwhile, the water droplet slow-fall section 531 has an upper surface that extends obliquely upward from the end of the through hole 521 near the mist inlet 532, gradually moving away from the through hole 521. This allows water droplets that pass through the through hole 521 and fall into the water droplet slow-fall section 531 to form a smooth, wall-attached flow along the upper surface of the water droplet slow-fall section 531, before slowly sliding down through the mist inlet 532 to the water surface of the mist outlet chamber 2.

[0032] Please see Figure 1 and Figure 3 In a preferred embodiment, the upper surface of the water droplet slow-fall portion 531 is an arc-shaped upper surface that extends obliquely upward from one end of the through hole 521 near the mist inlet 532 and gradually moves away from the through hole 521. The arc-shaped upper surface of the water droplet slow-fall portion 531 can closely conform to the natural flow trajectory of the water droplet, realizing a smooth transition of the water droplet from vertical to oblique, thereby guiding the water droplet to fall slowly.

[0033] Please see Figure 3 and Figure 4 In a preferred embodiment, each of the water droplet slow-fall portions 531 is a curved rib 5311, and the longitudinal projection of the curved rib 5311 overlaps with the longitudinal projection area of ​​the through hole 521.

[0034] Please see Figure 1 , Figure 3 In a preferred embodiment, the inner cavity of the water-blocking member 5 narrows from top to bottom; the water-blocking member 5 includes an upper section 51, a lower section 53 and a transition section 52, the upper section 51 is detachably connected to the end of the mist guiding cavity 4 near the mist outlet cavity 2; the inner diameter of the upper section 51 is larger than the inner diameter of the lower section 53; the side wall of the transition section 52 is provided with the through hole 521, and the outer side wall of the lower section 53 is provided with the water droplet slow-fall portion 531.

[0035] Specifically, the upper section 51 is a cylindrical section, and the transition section 52 and the lower section 53 are frustum-shaped sections. The cylindrical upper section 51 has a regular shape and is detachably connected to the end of the mist guiding cavity 4 near the mist outlet cavity 2, providing a basis for the stable connection of the water-blocking component 5. The through hole 521 of the frustum-shaped transition section 52 and the water droplet slow-fall part 531 of the frustum-shaped lower section 53 work together to ensure that most of the water droplets generated by condensation or collision in the water mist can slide off to the water surface after being buffered by the water-blocking component 5. By dividing the water-blocking component 5 into the upper section 51, the lower section 53 and the middle transition section 52, the functional zoning of the water-blocking component 5 is realized.

[0036] In this embodiment, the upper segment 51 is a cylindrical segment, and the lower segment 53 is a frustum-shaped segment.

[0037] Please see Figure 2 , Figure 3 In a preferred embodiment, at least two locking blocks 511 are provided on the outer wall of the upper section 51, and at least two locking slots 41 are provided at the end of the mist guiding chamber 4 near the mist outlet chamber 2, with the locking blocks 511 engaging with the locking slots 41. This ensures that the water-blocking component 5 can be fixed to the end of the mist guiding chamber 4 near the mist guiding chamber via the locking structure of the locking blocks 511 and locking slots 41; simultaneously, when the water-blocking component 5 needs cleaning or replacement, the user can easily complete the disassembly and assembly operations. It is understood that the number of locking blocks 511 and locking slots 41 includes, but is not limited to, 2, 3, or 4; the shapes of the locking blocks 511 and locking slots 41 include, but are not limited to, rectangles and trapezoids.

[0038] In this embodiment, there are two card blocks 511 and card slots 41; the card blocks 511 and card slots 41 are rectangular with matching shapes, and the rectangular card blocks 511 have the same axial length as the outer side wall of the upper section 51.

[0039] Furthermore, the locking block 511 and the locking groove 41 are evenly distributed circumferentially along the outer side wall of the upper section 51 of the water-blocking component 5 and the inner side wall of the mist-guiding cavity 4, respectively. This circumferential even distribution of the locking block 511 and the locking groove 41 ensures that the water-blocking component 5 experiences balanced force in the circumferential direction after engaging with the mist-guiding cavity 4, preventing tilting or shaking of the water-blocking component 5 due to unilateral force during humidifier use.

[0040] Please see Figure 1 In a preferred embodiment, the humidifier further includes a fan 31, which is disposed within the configuration space 3, with its outlet aligned with the mist guiding chamber 4. An air inlet 512 is provided on the side wall of the upper section 51. Thus, the airflow generated by the fan 31 can smoothly enter the mist guiding chamber 4 through the air inlet 512, thereby guiding the water mist generated by the vibration of the ultrasonic module through the mist guiding chamber 4 and quickly discharging it from the humidifier. Therefore, when the water-blocking component 5 is installed on the mist guiding chamber 4, it effectively reduces the water noise of the humidifier without affecting the airflow of the humidifier.

[0041] As a preferred embodiment, the water-blocking component 5 is integrally molded. Manufacturing the integrally molded water-blocking component 5 through processes such as injection molding not only ensures efficient production and simplified installation, but also maintains the integrity and smoothness of the arc-shaped upper surface without any seams, thereby providing a reliable guarantee for the smooth flow of water droplets and ensuring that the water-blocking component 5 effectively reduces noise.

[0042] Please see Figure 1 , Figure 2 In a preferred embodiment, the mist guiding cavity 4 is a conical channel, and the cross-sectional area of ​​the end of the mist guiding cavity 4 near the mist outlet 2 is greater than the cross-sectional area of ​​the end of the mist guiding cavity 4 near the mist outlet 20.

[0043] By setting a conical mist guiding cavity 4, the water mist generated by the ultrasonic module vibration flows within the mist guiding cavity 4. As the cross-sectional area of ​​the mist guiding cavity 4 gradually decreases, the water mist naturally compresses and gathers, increasing the density of particles in the water mist and significantly shortening the contact distance between the water mist particles. This increases the probability of condensation of larger water droplets in the water mist and the probability of water droplets colliding with the inner wall of the mist guiding cavity 4, thereby promoting the formation and separation of larger water droplets in the water mist. Larger water droplets separated from the water mist detach from the flow path of the water mist under the action of gravity and slide down along the inner wall of the mist guiding cavity 4 or fall directly. When a water droplet reaches the end of the mist guiding cavity 4 near the mist outlet cavity 2, it is intercepted by a water baffle 5 located at the end of the mist guiding cavity 4 near the mist outlet cavity 2, and guided by the water baffle 5, it decelerates and slides down to the water surface. Thus, under the synergistic effect of the conical mist guiding chamber 4 and the water baffle 5, larger water droplets in the water mist are separated in advance and slowly slide down to the water surface, avoiding larger water droplets falling at a higher position, thereby reducing water noise; at the same time, the discharged water mist is finer.

[0044] For example, please refer to Figure 2 The mist outlet 20 is angled to discharge water mist and prevent external impurities from falling directly into the humidifier.

[0045] For example, please refer to Figure 1 The water supply component is a float component 21, which is used to transfer the water in the water storage chamber 1 to the mist outlet chamber 2 and maintain the water level in the mist outlet chamber 2.

[0046] For example, please refer to Figure 1 The bottom of the mist outlet chamber 2 is provided with an installation port 22, which is used to install the ultrasonic module.

[0047] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
