Description

Technical Field

[0001] This utility model relates to the field of humidifier technology, and more specifically to a humidifier with a flow guiding structure. Background Technology

[0002] In existing ultrasonic humidifiers, the atomizing plate atomizes water into fine cold mist through high-speed oscillation, and then transports the mist to the mist outlet through the mist collection chamber.

[0003] However, during operation, in addition to normal atomization and evaporation, some water droplets will form water droplets due to splashing or condensation of water vapor at the top, and drip vertically onto the high-speed atomizing plate, which can easily lead to the following problems:

[0004] 1. Unstable atomization, producing a "water droplet popping sound" or intermittent atomization interruption;

[0005] 2. The atomizing plate is subjected to water droplet impact over a long period of time, which affects its service life;

[0006] 3. Reduced fog output leads to a decreased user experience;

[0007] 4. Localized water accumulation inside the cavity can easily breed odors, mold, etc.

[0008] Most products on the market currently use sealing and hydrophobic coatings for protection, but they do not actively intervene in the movement path of condensed water droplets from a physical structure perspective, which leads to the widespread existence of the above-mentioned problems. Utility Model Content

[0009] In view of this, the present invention provides a humidifier with a flow guiding structure.

[0010] To achieve the above objectives, this utility model adopts the following technical solution: a humidifier with a flow guiding structure, comprising: a main unit, internally having an ultrasonic atomizing chamber and a water storage chamber, wherein an ultrasonic atomizer is installed in the main unit; an atomizing channel shell is provided in the main unit, the interior of the atomizing channel shell forming an atomizing channel, the atomizing channel connecting the ultrasonic atomizing chamber and a mist outlet; the lower end of the atomizing channel is located above the ultrasonic atomizer, and a flow guiding shell is provided at the lower end of the atomizing channel; the flow guiding shell comprises: a side panel and a bottom plate, the side panel having multiple air inlets connecting the ultrasonic atomizing chamber and the atomizing channel, the bottom plate being connected to the bottom of the side panel, and the upper surface of the bottom plate being gradually inclined downward from the center to the periphery.

[0011] As a preferred embodiment of the present invention, the atomizing channel shell includes: a first shell and a second shell, the first shell being tubular and having an interior forming the atomizing channel; the second shell being located below the first shell, the lower part of the second shell extending to the inner bottom wall near the ultrasonic atomizing cavity.

[0012] As a preferred embodiment of this utility model, a flow guiding gap is formed between the outer edge of the base plate and the inner side of the second shell, and the width of the flow guiding gap is 1mm-4mm.

[0013] In a preferred embodiment of this utility model, the width of the flow guiding gap is 2mm.

[0014] As a preferred embodiment of this utility model, the first shell and the second shell are integrally injection molded, and the interiors of the first shell and the second shell are connected.

[0015] As a preferred embodiment of this utility model, the flow guide shell is detachably installed at the lower end of the atomization channel by any one of the following methods: threaded connection, snap-fit ​​connection, screw-fit connection, or snap-fit ​​connection.

[0016] In a preferred embodiment of this utility model, the ultrasonic atomizer includes an ultrasonic atomizing plate; the inner bottom wall of the ultrasonic atomizing cavity is provided with a countersunk hole, and the ultrasonic atomizing plate is located in the countersunk hole.

[0017] In a preferred embodiment of this invention, the projection of the atomizing channel shell onto the inner bottom wall of the ultrasonic atomizing cavity covers the countersunk hole.

[0018] As a preferred embodiment of this utility model, the host is provided with a fan assembly.

[0020] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0021] 1. The guide shell of this utility model effectively blocks the top condensate or splashing water droplets from falling directly into the atomization area through physical shielding and guidance, preventing them from dripping directly onto the ultrasonic atomizing plate, and guiding them to flow into the return water area along the inner side of the second shell, thereby improving atomization stability, extending the life of the ultrasonic atomizing plate, and optimizing the user experience.

[0022] 2. The assembly method between the guide shell and the atomizing channel shell in this utility model is simple and easy to disassemble. The bottom plate of the guide shell is inclined, which is more conducive to guiding the water flow to the inner side of the second shell and flowing down along the inner side to return to the return water area.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] For humidifiers with a flow guiding structure, please refer to [link / reference]. Figure 1-6 As shown, it includes: a main unit 100, which has an ultrasonic atomizing chamber 101 and a water storage chamber 102 internally, and an ultrasonic atomizer 110 installed in the main unit 100; the main unit 100 is provided with an atomizing channel shell 120, and the atomizing channel shell 120 internally forms an atomizing channel 103, which connects the ultrasonic atomizing chamber 101 and the mist outlet 104.

[0037] Specifically, the main unit 100 can be an integrated structure or a split structure. The split structure can include an upper body and a base. The upper body can be installed on the base, or the upper body can be removed from the base.

[0038] Regardless of whether it is an integrated structure or a split structure, the main unit 100 contains an ultrasonic atomizing chamber 101 and a water storage chamber 102. The water storage chamber 102 is located above the ultrasonic atomizing chamber 101. The ultrasonic atomizing chamber 101 and the water storage chamber 102 are connected by a fluid channel. The fluid channel is equipped with a bidirectional flow guide valve. When the bidirectional flow guide valve controls the fluid channel to open, water from the water storage chamber 102 flows into the ultrasonic atomizing chamber 101. When the bidirectional flow guide valve controls the fluid channel to close, water from the water storage chamber 102 stops flowing into the ultrasonic atomizing chamber 101.

[0039] The lower end of the atomizing channel 103 is located above the ultrasonic atomizer 110. A guide shell 200 is provided at the lower end of the atomizing channel 103. The guide shell 200 mainly guides the condensed water to flow downward from the edge of the guide shell 200 or from the inner side 1221 of the atomizing channel shell 120, so as to prevent the condensed water from dripping directly onto the ultrasonic atomizing plate 111 of the ultrasonic atomizer 110.

[0040] Specifically, such as Figure 3 and Figure 6 As shown, the flow guide shell 200 includes: a side panel 210 and a bottom plate 220. The side panel 210 and the bottom plate 220 can be snap-fit ​​together, or the side panel 210 and the bottom plate 220 can be directly integrated into one piece to reduce assembly steps.

[0041] The side panel 210 is provided with a plurality of air inlets 211 that connect the ultrasonic atomizing chamber 101 and the atomizing channel 103. The air inlets 211 are located at the connection between the side panel 210 and the base plate 220, so that water droplets falling into the space enclosed by the side panel 210 can fall onto the base plate 220 and flow through the air inlets 211 to the periphery of the base plate 220.

[0042] Furthermore, the upper surface of the base plate 220 is inclined downward from the center to the surrounding area, which can guide water droplets to flow in all directions;

[0043] In addition, the air inlet 211 can also be used when the ultrasonic atomizing plate 111 generates water mist, and the water mist enters the atomization channel 103 through the air inlet 211 and then flows out from the mist outlet 104.

[0044] In one implementation, such as Figure 4-5 As shown, the atomizing channel shell 120 includes: a first shell 121 and a second shell 122, which are integrally injection molded and internally connected; the first shell 121 is tubular and internally forms the atomizing channel 103; the second shell 122 is located below the first shell 121, and the lower part of the second shell 122 extends to the inner bottom wall near the ultrasonic atomizing cavity 101. Water flows from the lower part of the second shell 122 and the inner bottom wall of the ultrasonic atomizing cavity 101 to the location of the ultrasonic atomizing plate 111, and the water mist generated by the operation of the ultrasonic atomizing plate 111 can be concentrated in the space enclosed by the lower part of the second shell 122, so that the water mist can be concentrated and flow upward from the atomizing channel 103 and flow out from the mist outlet 104;

[0045] Continue as Figure 4-5 As shown, the atomizing channel shell 120 further includes a third shell 123, which extends outward from the middle of the second shell 122. The third shell 123 is integrally formed with the first shell 121 and the second shell 122, reducing assembly steps; as shown Figure 2 and Figure 3 As shown, the third housing 123 can be used as a partition to divide the main unit 100 into an ultrasonic atomizing chamber 101 and a water storage chamber 102.

[0046] In one implementation, such as Figure 3 and Figure 5 As shown, a flow guiding gap 105 is formed between the outer edge of the base plate 220 and the inner side surface 1221 of the second housing 122, and the width of the flow guiding gap 105 is 1mm-4mm.

[0047] As the water mist flows upward, condensation forms on the inner wall of the mist outlet 104 and the atomization channel 103. The condensation drips downward onto the guide shell 200. When the condensation flows toward the edge of the base plate 220, due to the relatively small width of the guide gap 105, the condensation will come into contact with the inner side 1221 of the second shell 122, and then flow downward along the inner side 1221 of the second shell 122, returning to the ultrasonic atomization chamber 101.

[0048] like Figure 5 As shown, an air inlet should also be provided within the space enclosed by the second housing 122, so that the water mist can be blown out from the mist outlet 104 by airflow. Therefore, Figure 5 In the second housing 122, two protrusions 1222 are provided inside, dividing the interior of the second housing 122 into two chambers, which are connected. The guide shell 200 is installed in the first chamber, and the lower end of the atomizing channel 103 is also located in the first chamber. The second chamber is mainly configured to correspond to the air outlet duct of the fan assembly 140. The edge of the bottom plate 220 of the guide shell 200 is partially close to the inner side 1221, not the entire edge of the bottom plate 220; however, at least one-third of the edge of the bottom plate 220 is close to the inner side 1221 to ensure the guiding effect.

[0049] Preferably, the width of the flow guide gap 105 is 2 mm.

[0050] In one embodiment, the flow guide shell 200 is detachably installed at the lower end of the atomizing channel 103 by any one of the following methods: threaded connection, snap-fit ​​connection, screw-fit connection, or snap-fit ​​connection;

[0051] Specifically, the upper side of the flow guide shell 200 is provided with an insertion hole 201, and the inner top of the second shell 122 is provided with an insertion post 1223. The insertion post 1223 is inserted into the insertion hole 201, and the flow guide shell 200 is stably installed inside the second shell 122.

[0052] In one embodiment, the ultrasonic atomizer 110 includes an ultrasonic atomizing plate 111; the inner bottom wall of the ultrasonic atomizing cavity 101 is provided with a countersunk hole 1011, and the ultrasonic atomizing plate 111 is located in the countersunk hole 1011.

[0053] Furthermore, the projection of the atomizing channel shell 120 onto the inner bottom wall of the ultrasonic atomizing cavity 101 covers the countersunk hole 1011, so that the water mist generated by the operation of the ultrasonic atomizing plate 111 is concentrated and enters the atomizing channel 103.

[0054] Furthermore, the host 100 is provided with a fan assembly 140, which effectively blows water mist out from the mist outlet 104.

[0055] Furthermore, the main unit 100 is provided with a cover 130 on the top, and the cover 130 is provided with the mist outlet 104; opening the cover 130 can facilitate the replenishment of water into the water storage chamber 102; the main unit 100 is provided with an electronic board and a control board, and the humidifier is controlled by the control board.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0057] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
