Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a humidifier. Background Art

[0002] As an indispensable device in modern home and office environments, humidifiers are becoming increasingly important. Humidifiers increase the humidity in the air by releasing mist (fine water droplets), which plays a significant role in improving the indoor environment and enhancing living and working comfort. In dry seasons or environments, humidifiers can effectively relieve problems such as dry skin and sore throats, creating a more comfortable and healthy living environment for users.

[0003] During the use of the humidifier, the diffusion mode of the mist has become one of the key factors affecting the efficiency and performance of the humidifier. Traditional humidifiers generally use a vertically arranged mist outlet pipe, and the mist is directly discharged to the outside along the vertical direction of the mist outlet pipe. Although this design is simple and easy to implement, it has obvious limitations. Since the mist mainly flows in the vertical direction, it is difficult to effectively diffuse around in a short time, resulting in uneven indoor humidity distribution and reduced humidification efficiency. This not only affects the use effect of the humidifier, but may also cause damage to indoor items, such as causing books and furniture to become damp and deformed.

[0004] In order to improve this problem, the industry has proposed some solutions. Among them, a common practice is to cover the opening of the mist outlet pipe and set a mist outlet hole on the side of the cover that deviates from the central axis of the mist outlet pipe. The mist needs to bend when flowing out to reach the mist outlet hole, thereby changing the flow direction of the mist to a certain extent, allowing it to diffuse around. However, this method still has obvious shortcomings. Since the mist outlet pipe has a long length, the angle at which the mist deviates during the flow is limited, resulting in the mist not being able to diffuse evenly around, affecting the diffusion efficiency of the mist.

[0005] In addition, when the mist flows from the mist outlet pipe to the nozzle and turns at the mist outlet, its dynamic characteristics become complicated. Since the water droplets in the mist have a certain mass and speed, they will be affected by centrifugal force when they encounter the turning point of the mist outlet. This centrifugal force causes part of the water mist to separate from the main airflow and adhere to the inner wall of the mist outlet, gradually accumulating to form small water droplets. Over time, these small water droplets continue to accumulate on the inner wall of the mist outlet and eventually converge into large water droplets. These large water droplets will block the mist outlet, causing the mist to be unable to be discharged normally, thereby affecting the mist outlet efficiency of the humidifier. In some cases, the mist outlet may even be completely blocked, causing the humidifier to fail to work properly, causing inconvenience to the user. Moreover, when the mist outlet is blocked, the water pressure inside the humidifier will gradually increase, increasing the risk of damage to the humidifier. At the same time, the blocked mist outlet may also cause bacteria or mold to grow inside the humidifier, posing a potential threat to the health of users. Utility Model Content

[0006] The primary purpose of the present invention is to solve at least one of the above problems and provide a humidifier.

[0007] In order to meet the various purposes of the utility model, the utility model adopts the following technical solutions:

[0008] A humidifier is provided to meet one of the purposes of the utility model, including a main body and a mist guide assembly.

[0009] The main body is provided with an atomizing assembly and a vertically arranged mist outlet channel, and the mist outlet channel is formed with a mist outlet.

[0010] The mist guide assembly includes a mist guide cover, a spoiler and a guide plate. The mist guide cover covers the mist outlet channel and is provided with a mist outlet hole. The spoiler is disposed transversely on the mist outlet channel to form a constriction in the mist outlet channel. The guide plate is convexly disposed on the bottom surface of the mist guide cover to separate the constriction from the mist outlet hole and be disposed on both sides of the guide plate.

[0011] The mist generated by the atomizing assembly enters the mist outlet channel, passes through the turning path between the narrow passage and the mist outlet hole, and diffuses outward from the mist outlet hole.

[0012] Furthermore, when the mist flows through the narrow opening to the mist outlet hole, the angle between the flow direction of the mist and the gravity direction of the mist is less than 45°.

[0013] Specifically, the mist outlet hole is arranged opposite to the spoiler, and the spoiler is in contact with the side wall of the mist guide cover or the side wall of the mist outlet channel.

[0014] Specifically, the guide plate is arranged opposite to the spoiler, and one end of the spoiler close to the narrow passage is arranged in a staggered manner with respect to the guide plate.

[0015] In one embodiment, assuming that the ground is a reference plane, the mist outlet hole and the guide plate are arranged side by side, and one of the side edges of the mist outlet hole is arranged adjacent to the guide plate, and in the projection direction of the ground, the shape of the projection of the guide plate on the ground is substantially the same as the shape of the projection of one of the side edges of the mist outlet hole.

[0016] In one embodiment, the mist guide assembly further includes a water guide plate, which is convexly arranged on the bottom surface of the mist guide cover, and the water guide plate and the flow guide plate are respectively arranged on both sides of the mist outlet hole.

[0017] In one embodiment, the water guide plate is farther away from the narrow opening than the flow guide plate, and the water guide plate is extended to fit the other side of the mist guide hole. The ground is assumed to be a reference plane. In the projection direction of the ground, the shape of the projection of the water guide plate is substantially the same as the shape of the projection of the other side of the mist outlet hole.

[0018] In one embodiment, the height of the guide plate protruding toward the spoiler is associated with the mist outlet efficiency of the mist outlet hole.

[0019] In one embodiment, the mist guide assembly further includes a mist guide plate, which is obliquely arranged on the spoiler and the bottom of the mist guide plate is connected to the spoiler, and the bottom of the mist guide plate is arranged close to the narrow opening.

[0020] In one embodiment, the angle between the mist guide plate and the spoiler is an acute angle.

[0021] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0022] On the one hand, the humidifier of the utility model forms a bottleneck by setting a spoiler in the mist outlet channel. When the mist passes through this bottleneck, it will be disturbed, so that the flow direction of the mist changes, and then rotation or eddy current is generated. This rotation or eddy current effect helps to evenly distribute and diffuse the mist. At the same time, the setting of the guide plate forms a turning path between the bottleneck and the mist outlet. When the mist passes through this path, it will be further dispersed and guided, ensuring that the mist can cover a wider range when it diffuses outward from the mist outlet, so as to achieve even distribution of the mist.

[0023] On the other hand, during the operation of the humidifier, when the mist is disturbed and turned, the mist will be subjected to centrifugal force, and part of the mist will be converted into water droplets. However, the guide plate is convexly arranged on the bottom surface of the mist guide cover to collect water droplets. The water droplets will slide down the guide plate and will be effectively guided to the bottom of the mist outlet channel instead of being blocked on the mist outlet hole. In this way, the water droplets are prevented from blocking the mist outlet hole, ensuring that the humidifier continuously and stably provides mist. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The utility model provides a humidifier, which forms a bottleneck in the mist outlet channel through a spoiler. The bottleneck cooperates with the mist outlet hole of the mist guide cover to make the mist vapor undergo multiple turns in the channel, thereby improving the diffusion uniformity and diffusion range of the mist vapor. At the same time, the guide plate can guide water droplets to avoid clogging the mist outlet, thereby improving the reliability and humidification efficiency of the humidifier and bringing a better use experience to users.

[0040] In a typical embodiment of the present invention, Figure 1 The humidifier 100 includes a main body 110 and a mist guide component. The main body 110 includes a water storage cavity 111, a base 112, an atomization component 113, a mist outlet component and a control component. The water storage cavity 111 is located on the base 112.

[0041] Combination Figure 4An atomizing channel 114 is provided in the base 112, and a drain hole (not shown) is provided at the bottom of the water storage cavity 111. The water storage cavity 111 is connected to the atomizing channel 114 through the drain hole. Through the drain hole, the water storage cavity 111 can output liquid to the atomizing channel 114. The liquid includes but is not limited to water, essential oil, etc. The following description is based on the liquid in the water storage cavity 111, taking water as an example, to describe the present invention, but it should not be understood as a limitation to the present invention.

[0042] The atomizing assembly 113 is disposed in the atomizing channel 114, and is used to atomize the water output from the water storage chamber 111 to the atomizing channel 114 into mist. In this embodiment, it is recommended that the atomizing assembly 113 is an ultrasonic atomizing assembly 113, which atomizes the water into mist through ultrasonic vibration.

[0043] The mist outlet assembly includes a mist outlet channel 120, and the mist outlet channel 120 is connected to the atomizing channel 114, so that the mist vapor formed by atomization of the atomizing assembly 113 in the atomizing channel 114 can be discharged from the humidifier 100 through the mist outlet channel 120. In this embodiment, the mist outlet assembly also includes a fan 115, and the fan 115 is arranged in the atomizing channel 114, and wind is generated by the rotation of the fan 115 to increase the rate at which the mist vapor is discharged from the humidifier 100. The control assembly is electrically connected to the fan 115, and the control assembly controls the rotation speed of the fan 115 to control the discharge rate of the mist vapor of the humidifier 100. The control assembly includes but is not limited to a single-chip microcomputer, a control chip, and the like.

[0044] Combination Figure 3 , the mist outlet channel 120 is arranged vertically, and the mist outlet channel 120 is formed with a mist outlet 121, and the mist outlet 121 is arranged at the top of the vertical direction of the mist outlet channel 120. After the mist vapor flows into the mist outlet channel 120 from the atomization channel 114, it flows from the bottom of the mist outlet channel 120 to the mist outlet 121 arranged at the top of the mist outlet channel 120 along the vertical direction, and flows out of the humidifier 100 through the mist outlet 121 to humidify the external environment. In this embodiment, the mist outlet channel 120 is a pipeline structure, and the mist outlet channel 120 is fixedly arranged in the water storage cavity 111, and the mist outlet 121 is also opened at the top of the water storage cavity 111. Preferably, the mist outlet channel 120 and the water storage cavity 111 are integrally formed.

[0045] In a typical embodiment of the present invention, the mist guide assembly includes a mist guide cover 130 , a spoiler 140 and a guide plate 150 .

[0046] Combination Figure 2 and Figure 5, the mist guide cover 130 covers the mist outlet 121, and the mist guide cover 130 covers the entire mist outlet 121 to close the mist outlet 121. The mist guide cover 130 is provided with a mist outlet hole 131, and the mist can flow out of the mist outlet channel 120 through the mist outlet hole 131 to humidify the external environment. The mist outlet hole 131 is arranged on one side of the mist guide cover 130, deviating from the central axis of the vertical direction of the mist outlet channel 120, so that the mist cannot flow directly to the outside along the vertical direction, so as to avoid the mist from flowing in only one direction after flowing out of the mist outlet hole 131, and cannot diffuse to the surroundings, thereby causing uneven humidity distribution in the external environment.

[0047] In one embodiment, the mist guide cover 130 is integrally formed with the mist outlet channel 120. Further, the mist outlet channel 120 is integrally formed with the water storage cavity 111, and it can be understood that the mist guide cover 130 is also integrally formed with the water storage cavity 111.

[0048] Combination Figure 3 and Figure 5 The spoiler 140 is disposed horizontally in the mist outlet channel 120, and the spoiler 140 is disposed close to the mist outlet port 121. One end of the spoiler 140 is in contact with the side wall 122 of the mist outlet channel 120 or the side wall 132 of the mist guide cover 130. Since the spoiler 140 is disposed horizontally in the mist outlet channel 120 but does not close the mist outlet channel 120, a bottleneck 123 is formed between the spoiler 140 and the mist outlet channel 120, so that the mist can only bypass the bottleneck 123 to flow to the mist outlet port 131.

[0049] Specifically, the end of the spoiler 140 that is not in contact with the side wall 132 of the mist guide cover 130 or the side wall 122 of the mist outlet channel 120 is a protruding end 141, and the protruding end 141 and the mist outlet channel 120 form the bottleneck 123. The guide plate 150 is arranged opposite to the spoiler 140, and the protruding end 141 and the guide plate 150 are arranged in a staggered manner, so that after the mist flows out of the bottleneck 123, it can also bypass the guide plate 150 instead of directly flowing to the mist outlet hole 131.

[0050] In one embodiment, the spoiler 140 is an independent component, a support platform is provided in the mist outlet channel 120, and the spoiler 140 is mounted on the support platform.

[0051] In one embodiment, the spoiler 140 is connected to the side wall 122 of the mist outlet channel 120. Alternatively, the spoiler 140 is connected to the side wall 132 of the mist guide cover 130. Preferably, the spoiler 140 is integrally formed with the mist outlet channel 120. Alternatively, the spoiler 140 is integrally formed with the mist guide cover 130.

[0052] Combination Figure 5 The mist outlet hole 131 is arranged at a position directly opposite to the spoiler 140, so that the mist cannot flow to the mist outlet hole 131 along the vertical direction. The mist needs to bypass the narrow pass 123 before it can flow to the mist outlet hole 131. It can be understood that after the mist bypasses the narrow pass 123, the mist will change its flow direction, so that the mist can no longer flow out of the mist outlet hole 131 along the vertical direction, so that the mist can diffuse to the surroundings after flowing out of the mist outlet hole 131, thereby improving the uniformity of the mist distribution in the external environment.

[0053] Moreover, because the spoiler 140 is disposed transversely in the mist outlet channel 120, the area of ​​the bottleneck 123 is smaller than the cross-sectional area of ​​the mist outlet channel 120. When the mist passes through the bottleneck 123, the flow rate of the mist will be increased, and the rate at which the mist flows out of the humidifier 100 will be accelerated, thereby improving the humidification efficiency of the humidifier 100.

[0054] Combination Figure 2 and Figure 5 The guide plate 150 is convexly disposed on the bottom surface of the mist guide cover 130, and the guide plate 150 is convexly disposed toward the spoiler 140. In other words, the guide plate 150 is hung upside down on the bottom surface of the mist guide cover 130. The narrow opening 123 and the mist outlet hole 131 are disposed on both sides of the guide plate 150. It can be understood that the mist outlet channel 120 is disposed vertically relative to the ground, and the ground is used as a reference system. In the projection direction of the ground, the projection of the narrow opening 123 and the projection of the mist outlet hole 131 are disposed on both sides of the projection of the guide plate 150.

[0055] Furthermore, the guide plate 150 is disposed near the mist outlet hole 131. After the mist flows through the narrow opening 123, in the process of flowing to the mist outlet hole 131, the mist needs to bypass the guide plate 150 before flowing to the mist outlet hole 131. When the mist bypasses the guide plate 150, the mist changes its flow direction again, so that the flow direction of the mist further deviates from the vertical direction, and then the mist is dispersed to the surroundings after flowing out of the mist outlet hole 131, so as to evenly change the humidity of the external environment.

[0056] In this embodiment, the horizontal spacing between the guide plate 150 and the mist outlet hole 131 can also be adjusted to adjust the angle at which the mist flows out of the mist outlet hole 131. When the guide plate 150 is too close to the mist outlet hole 131, the mist will need to make a sharp turn after flowing to the guide plate 150, so that the flow resistance of the mist becomes larger and the amount of mist becomes smaller; when the guide plate 150 is too far from the mist outlet hole 131, the guide plate 150 cannot adjust the angle of the mist well, so that the mist cannot be well diffused around. Therefore, the horizontal spacing between the guide plate 150 and the mist outlet hole 131 is an important indicator that affects the mist outlet angle and the amount of mist. After knowing the technical solution of the utility model, those skilled in the art can reasonably adjust the horizontal spacing between the guide plate 150 and the mist outlet hole 131 according to the volume of the humidifier 100. In order to save space, it will not be repeated here. In this embodiment, it is recommended that the horizontal spacing between the guide plate 150 and the mist outlet hole 131 is 3-6 mm, but this should not be construed as a limitation to the present invention.

[0057] In one embodiment, the path of the mist flowing from the narrow pass 123 to the mist outlet hole 131 is called a turning path. By setting the guide plate 150, the mist turns again after bypassing the spoiler 140. In the projection direction of the ground, the projection of the guide plate 150 and the projection of the protruding end 141 are arranged at intervals, and the distance between the projection of the guide plate 150 and the projection of the protruding end 141 is associated with the discharge angle of the mist. The angle at which the mist flows out of the mist outlet hole 131 is changed by adjusting the distance between the projection of the guide plate 150 and the projection of the protruding end 141. After knowing the technical solution of the utility model, those skilled in the art can reasonably adjust the distance between the guide plate 150 and the protruding end 141 according to the volume of the humidifier 100 to adjust the discharge angle of the mist. In order to save space, it will not be repeated here.

[0058] In a typical embodiment of the present invention, Figure 5, because the flow direction of the mist is not parallel to the vertical direction, when the mist bypasses the guide plate 150 and flows to the mist outlet hole 131, the flow path of the mist is a curve, so that the mist will be affected by the centrifugal force, causing some tiny water droplets in the mist to separate from the mist under the action of the centrifugal force, and some tiny water droplets converge with each other to form small water droplets. Generally speaking, the small water droplets will block the mist outlet hole 131. However, in this embodiment, due to the provision of the guide plate 150, part of the mist will form small water droplets on the guide plate 150, so that the small water droplets will slide along the guide plate 150 toward the bottom of the mist outlet channel 120 under the action of their own gravity, and will drip onto the spoiler 140, and even drip onto the bottom of the mist outlet channel 120, and even flow back into the atomization channel 114, and re-atomize, so that the mist outlet hole 131 will not be blocked by the small water droplets, and the humidifier 100 can discharge the mist well.

[0059] In one embodiment, when the mist passes through the narrow pass 123 and bypasses the guide plate 150 to flow to the mist outlet 131, the mist is redirected by the spoiler 140 and the guide plate 150, so that the flow direction of the mist is inclined to the vertical direction of the mist outlet channel 120. However, since there are a number of small water droplets in the mist, the small water droplets have gravity, so that the mist has a downward gravity. There is an angle between the flow direction of the mist and the gravity direction of the mist, and the angle is less than 45°. According to mechanical analysis, since the flow direction of the mist is different from the gravity direction, the small water droplets in the mist have centrifugal force, so that the small water droplets can be separated from the mist.

[0060] Because the guide plate 150 is arranged close to the mist outlet hole 131, the small water droplets separated from the mist will gather on the guide plate 150, and the small water droplets will flow downward along the guide plate 150, so that the small water droplets will drip onto the spoiler 140 or drip to the bottom of the mist outlet channel 120, thereby preventing the small water droplets separated from the mist from clogging the mist outlet hole 131.

[0061] In one embodiment, the guide plate 150 is protruding from the bottom surface of the mist guide cover 130, and the height of the guide plate 150 protruding toward the spoiler 140 will affect the dripping of the small water droplets. Specifically, when the height of the guide plate 150 is low, the mist will give the small water droplets a lifting force along the vertical direction, that is, a lifting effect is generated, thereby preventing the small water droplets from sliding along the guide plate 150, and then causing the small water droplets to block the mist outlet 131; when the height of the guide plate 150 is high, the detour path of the mist is too long, so that the amount of mist is reduced. Therefore, the height of the guide plate 150 protruding toward the spoiler 140 is an important indicator of the humidifier 100. After knowing the technical solution of the utility model, those skilled in the art can reasonably adjust the height of the guide plate 150 protruding toward the spoiler 140 according to the volume of the humidifier 100. In order to save space, it will not be repeated here. In this embodiment, it is recommended that the height of the guide plate 150 protruding toward the spoiler 140 is 3-6 mm, but this should not be construed as a limitation to the present invention.

[0062] In a further embodiment, in combination Figure 2 , the guide plate 150 is extended along one of the side edges of the mist outlet hole 131 (the side edge is referred to as the first side edge 1311), and the shape of the guide plate 150 corresponds to the extension path of the first side edge 1311. In the projection direction of the ground, the projection shape of the guide plate 150 is substantially the same as the projection shape of the first side edge 1311. For example, the mist outlet hole 131 is an arc-shaped structure, that is, the first side edge 1311 corresponding to the guide plate 150 is an arc-shaped edge, and similarly, the guide plate 150 is also an arc-shaped structure, so that the guide plate 150 redirects the mist vapor flowing from the narrow pass 123 to the guide plate 150 and guides the water droplets. For another example, the mist outlet 131 has a rectangular structure, that is, the first side 1311 corresponding to the guide plate 150 is a straight edge. Similarly, the projection of the guide plate 150 in the ground direction is also a straight structure, so that the guide plate 150 can redirect the mist flowing from the narrow pass 123 to the guide plate 150 and guide the water droplets.

[0063] In one embodiment, in combination Figure 6 , Figure 7 and Figure 8 The mist guide assembly also includes a water guide plate 160, which is also convexly arranged on the bottom surface of the mist guide cover 130, and the water guide plate 160 and the guide plate 150 are arranged on both sides of the mist outlet hole 131. The water guide plate 160 is used to further collect small water droplets generated by the mist vapor under the action of centrifugal force to prevent the small water droplets from clogging the mist outlet hole 131.

[0064] Specifically, in the horizontal direction, the water guide plate 160 is arranged farther away from the narrow pass 123 than the guide plate 150, so that the water guide plate 160 is opposite to the mist after bypassing the guide plate 150, so that small water droplets separated by the mist due to centrifugal force gather on the water guide plate 160, and then drip onto the spoiler 140 through the water guide plate 160, and even to the bottom of the mist outlet channel 120, and even diverted to the atomization channel 114 for re-atomization.

[0065] The water guide plate 160 is extended along the side edge corresponding to the mist outlet hole 131 (the side edge is referred to as the second side edge 1312), and the water guide plate 160 is arranged in close contact with the second side edge 1312 to eliminate the horizontal gap between the water guide plate 160 and the mist outlet hole 131, so that the small water droplets separated from the mist can directly drip through the water guide plate 160 without being stored between the water guide plate 160 and the mist outlet hole 131, thereby preventing the small water droplets from clogging the mist outlet hole 131.

[0066] Furthermore, the water guide plate 160 is convexly disposed on the bottom surface of the mist guide cover 130, and the height of the water guide plate 160 protruding toward the spoiler 140 will affect the gathering of small water droplets on the water guide plate 160. The greater the height of the water guide plate 160, the more small water droplets can be gathered, thereby reducing the possibility of small water droplets blocking the mist outlet hole 131. In this embodiment, it is recommended that the height of the water guide plate 160 is 12-16 mm.

[0067] In a further embodiment, in combination Figure 6 , in the projection direction of the ground, the shape of the projection of the water guide plate 160 is substantially the same as the shape of the projection of the second side 1312. For example, the mist outlet hole 131 is an arc-shaped structure, which means that the second side 1312 corresponding to the water guide plate 160 is an arc-shaped side, and similarly, the water guide plate 160 is also an arc-shaped structure. For another example, the mist outlet hole 131 is a rectangular structure, which means that the second side 1312 corresponding to the water guide plate 160 is a straight side, and similarly, the shape of the projection of the water guide plate 160 on the ground is also a straight structure.

[0068] In another embodiment, in combination Fig. 9 , Fig.10 and Fig.11, the mist guide assembly also includes a mist guide plate 170, the mist guide plate 170 is tilted on the spoiler 140, and the mist guide plate 170 is tilted toward the mist outlet hole 131, the bottom of the mist guide plate 170 is connected to the spoiler 140, and the bottom of the mist guide plate 170 is arranged close to the pass. The mist guide plate 170 is used to guide the mist vapor flowing through the pass 123 to the mist outlet hole 131 to prevent the mist vapor from forming small water droplets on the mist outlet hole 131 and blocking the mist outlet hole 131. In this embodiment, the mist guide plate 170 is arranged at an acute angle with the spoiler 140, and it is recommended that the mist guide plate 170 and the guide plate 150 are at an angle of 30-70°. Preferably, the mist guide plate 170 and the spoiler 140 are integrally formed.

[0069] Specifically, one end of the mist guide plate 170 facing the mist outlet hole 131 is the guide end 171, and the guide end 171 is directly opposite to the mist outlet hole 131. It can be understood that in the projection direction of the ground, the projection of the guide end 171 is located within the projection of the mist outlet hole 131. After the mist flows through the narrow opening 123, the mist is guided by the mist guide plate 170 so that the mist can flow smoothly to the mist outlet hole 131 and be discharged from the humidifier 100 through the mist outlet hole 131.

[0070] Moreover, small water droplets generated by the mist under the action of centrifugal force will also gather on the mist guide plate 170, and the small water droplets will flow to the spoiler 140 through the mist guide plate 170, and even to the bottom of the mist outlet channel 120, and even flow back to the atomization channel 114. Therefore, under the action of the mist guide plate 170 and the guide plate 150, the mist outlet hole 131 will not be blocked by the small water droplets.

[0071] In the vertical direction, the guide end 171 is spaced apart from the mist outlet hole 131 to prevent small water droplets formed on the guide end 171 from blocking the mist outlet hole 131. Preferably, in the vertical direction, the distance between the guide end 171 and the mist outlet hole 131 is 3-6 mm.

[0072] In another embodiment, the mist guide assembly is provided with a water guide plate 160 and a mist guide plate 170 to further guide the mist and guide the water droplets to drip, so as to prevent the water droplets from clogging the mist outlet hole 131 .

[0073] In summary, the humidifier of the utility model changes the flow direction of the mist by setting a spoiler and a guide plate, so that the mist can be dispersed to the surrounding areas to evenly humidify the external environment, and the guide plate can also collect small water droplets, so that the small water droplets drip along the guide plate to avoid the small water droplets clogging the mist outlet.

[0074] The above description is only a preferred embodiment of the utility model and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the utility model is not limited to the technical solution formed by a specific combination of the above technical features, but also should cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the above utility model. For example, the above features are replaced with the technical features of the utility model (but not limited to) with similar functions in the utility model of the utility model to form a technical solution.

[0075] Although the subject matter has been described in language specific to structural features and / or methodological logical actions, it should be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or actions described above. On the contrary, the specific features and actions described above are merely example forms of implementing the claims.
