Description

Technical Field

[0001] The utility model relates to the field of humidifiers, in particular to an upper-water-adding humidifier. Background Art

[0002] A humidifier is a household appliance used to increase the humidity in spaces such as rooms. It mainly uses high-frequency oscillation, and through the high-frequency vibration of the atomizing sheet, the water in the humidifier is thrown off the water surface to generate floating water mist, so as to achieve the purpose of air humidification. Humidifiers are divided into upper-water-adding humidifiers and lower-water-adding humidifiers. Among them, the upper-water-adding humidifier has the advantage of convenient water addition and is deeply welcomed by consumers.

[0003] Chinese patent document with the publication number of CN220321501U discloses an upper-water-adding humidifier, which includes a base with a receiving cavity inside, an atomizing circuit board arranged in the receiving cavity, a fan arranged in the receiving cavity, a water tank detachably arranged on the base, an atomizing sheet connected to the bottom of the water tank, and an air outlet pipe arranged in the water tank, etc. When the disclosed upper-water-adding humidifier works, the atomizing sheet at the bottom of the water tank oscillates to atomize the water in the water tank. At the same time, the fan blows air into the air outlet pipe, so that the water mist in the water tank can be blown out of the humidifier.

[0004] However, during the process of the user adding water to the water tank, the water easily splashes from the air outlet of the air outlet pipe into the air outlet pipe, and then drips onto the electrical components in the receiving cavity. When the upper-water-adding humidifier works, there are relatively large potential safety hazards.

[0005] In addition, the receiving cavity is communicated with the water tank through the air outlet pipe, and the inside of the water tank is in a humid environment, which also makes the humidity in the receiving cavity high, and will shorten the service life of the electrical components therein.

[0006] It can be seen that the existing technology still needs to be improved. Summary of the Utility Model

[0007] The purpose of the utility model is to provide an upper-water-adding humidifier, which is provided with a water-blocking cover at the upper end of the air outlet pipe, can avoid the water in the water tank from splashing into the air outlet pipe, makes the product safer to use, and at the same time improves the service life of the electrical components inside the upper-water-adding humidifier.

[0041] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0042] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0043] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element present at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intermediate element present at the same time.

[0044] In addition, the descriptions involving "first", "second", etc. in the present utility model are only for descriptive purposes and cannot be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0045] Please refer to Figure 1 , the present utility model provides an upper-water adding humidifier, which includes a base 1 having a receiving cavity 101, a water tank 2 detachably disposed on the base 1, a top cover 3 detachably disposed on the top of the water tank 2, an air outlet pipe 4 vertically disposed in the water tank 2, a energy-gathering ring 5 movably sleeved on the air outlet pipe 4, an atomizing sheet 6 connected to the water outlet at the bottom of the water tank 2, a fan 7 disposed in the receiving cavity 101 and having an air outlet 413 below the air outlet pipe 4, an atomizing circuit board 8 disposed in the receiving cavity 101 and electrically connected to the atomizing sheet 6, and a water-blocking cover 9 covering the upper end of the air outlet pipe 4.

[0046] Among them, the energy-gathering ring 5 is an existing setting inside the water tank 2 of the upper-water adding humidifier. The energy-gathering ring 5 is provided with an energy-gathering channel above the atomizing sheet 6. When the upper-water adding humidifier works, the energy-gathering ring 5 gathers the high-frequency oscillation ability generated by the atomizing sheet 6, so that the water column oscillated by the atomizing sheet 6 can break through the water surface to generate water mist.

[0047] Among them, an air outlet 413 is provided on one side of the upper end surface 42 of the air outlet pipe 4 facing the inner wall of the water tank 2. When the upper-water adding humidifier works, the fan 7 discharges the inhaled air into the air outlet pipe 4 and discharges it into the water tank 2 through the air outlet 413 of the air outlet pipe 4, so that the water mist in the water tank 2 can be more easily discharged to the indoor environment through the mist outlet on the top cover 3 for humidifying the air.

[0048] Furthermore, the water baffle cover 9 includes an upper wall 91, two side walls 92, and a front wall 93. The upper wall 91, the side walls 92, and the front wall 93 can be integrally formed. Among them, the upper wall 91 simultaneously covers the upper side and the rear side 43 of the air outlet pipe 4; the two side walls 92 are respectively located on both sides of the upper wall 91 and are attached to the left side surface and the right side surface of the air outlet pipe 4; the front wall 93 is simultaneously connected to the front sides of the two side walls 92 and faces the air outlet 413, so that the air outlet 413 can be blocked by the front wall 93. During the process of the user adding water to the water tank 2, water splashing into the air outlet pipe 4 can be avoided, thereby preventing the electrical components (including the fan 7) in the accommodation cavity 101 from being immersed in water. When the top-water humidifier is working, the potential safety hazard is small, and at the same time, the service life of the electrical components can be extended.

[0049] And a first clamping plate 94 vertically arranged on the inner side of the front wall 93 abuts against the front side surface 44 of the air outlet pipe 4. Thus, an air outlet channel 95 can be formed between the front wall 93 and the front side surface 44 of the air outlet pipe 4, so that the air discharged from the air outlet pipe 4 can be discharged into the water tank 2 through the air outlet channel 95. While the water baffle cover 9 plays a role in blocking water, it will not affect the normal air outlet of the air outlet pipe 4.

[0050] In addition, in the present utility model, the air outlet 413 faces the inner wall of the water tank 2, rather than the central area inside the water tank 2 with a large amount of water mist, and the front side of the air outlet 413 is blocked by the front wall 93. Therefore, even if a small amount of water mist enters the air outlet channel 95 upward, the water mist is easily adsorbed onto the surface of the front side surface 44 of the air outlet pipe 4 and the first clamping plate 94, and thus it is difficult to deflect and cross over the air outlet 413 and enter the inside of the air outlet pipe 4. Thereby, it can prevent the water mist from entering the air outlet pipe 4 and the accommodation cavity 101 below its base 1. Therefore, the humidity in the accommodation cavity 101 will not be too high, and the electrical components inside are not easily damaged. Correspondingly, the service life of the electrical components can also be extended.

[0051] Specifically, the number of the first clamping plates 94 can be one, two, or more than two.

[0052] In a preferred embodiment of the present utility model, an opening 931 is provided on the lower side of the front wall 93, and the opening 931 is lower than the air outlet 413. Thus, not only can the air discharged from the air outlet pipe 4 be discharged into the water tank 2 through the air outlet channel 95, but also the air can laterally cross over the opening 931 and enter the water tank 2. The air discharged from the air outlet pipe 4 can easily enter the water surface inside the water tank 2, and the air outlet speed of the air outlet pipe 4 will not be affected by the setting of the water baffle cover 9.

[0053] In a preferred embodiment of the present utility model, a second clamping plate 96 is provided on the inner side of the upper wall 91 and abuts against the rear side surface 43 of the air outlet pipe 4. The second clamping plate 96 should be perpendicular to the horizontal plane. When the second clamping plate 96 and the first clamping plate 94 respectively abut against the rear side surface 43 and the front side surface 44 of the air outlet pipe 4, the water baffle 9 cannot move horizontally due to the restriction of the air outlet pipe 4, so that the water baffle 9 is not easily detached from the upper end of the air outlet pipe 4. Users do not need to frequently disassemble and assemble the water baffle 9, and the use experience of the top-water humidifier product is better.

[0054] It should be noted that the number of the second clamping plates 96 in this embodiment is not limited. It can be one, two, or even more than two.

[0055] In a preferred embodiment of the present utility model, a third clamping plate 97 extends from the front side of the side wall 92 towards the inner wall of the water tank 2. The third clamping plate 97 can abut against the inner wall of the water tank 2. When the third clamping plate 97 abuts against the inner wall of the water tank 2, it can prevent the air outlet pipe 4 from tilting towards the inner wall of the water tank 2, thereby ensuring that the air outlet pipe 4 is not easily deformed during use and the air outlet pipe 4 has a stable verticality.

[0056] In a preferred embodiment of the present utility model, a step 41 is provided on one side of the upper end surface 42 of the air outlet pipe 4 towards the inner wall of the water tank 2; the air outlet 413 is simultaneously provided on the horizontal step surface 411 and the vertical step surface 412 of the step 41, thereby improving the air outlet efficiency of the air outlet pipe 4 and promoting the air flow in the water tank 2, which helps the water mist to be blown out of the humidifier.

[0057] In a preferred embodiment of the present utility model, the upper end surface 42 of the air outlet pipe 4 is arc-shaped, and the upper end surface 42 of the air outlet pipe 4 extends downward to connect with the rear side surface 43 of the air outlet pipe 4. The upper wall 91 has an arc-shaped portion 912 corresponding to the upper end surface 42 of the air outlet pipe 4 and a horizontal portion 911 connected to the arc-shaped portion 912.

[0058] Since a second clamping plate 96 is provided on the inner side of the upper wall 91 and abuts against the rear side surface 43 of the air outlet pipe 4, a gap 10 will be left between the inner side of the upper wall 91 and the rear side surface 43 of the air outlet pipe 4. This gap 10 can accommodate the water mist. Based on this, in this preferred embodiment, the upper end surface 42 of the air outlet pipe 4 is designed to be arc-shaped, and the upper wall 91 has an arc-shaped portion 912 corresponding to the upper end surface 42 of the air outlet pipe 4. Thus, when the water mist enters the gap 10, the liquid water adsorbed on the upper end surface 42 of the air outlet pipe 4 and the inner side surface of the upper wall 91 can flow downward back into the water tank 2, making it difficult for the water mist entering the gap 10 to enter the side of the air outlet pipe 4 where the air outlet 413 is provided.

[0059] In a preferred embodiment of the present utility model, a water-blocking rib 11 is formed between the vertical step surface 412 of the step 41 extending upward and the upper end surface 42 of the air outlet pipe 4. The water-blocking rib 11 contacts the upper wall 91. When water mist enters the aforementioned gap 10, the water-blocking rib 11 blocks the water mist from entering the side of the air outlet pipe 4 where the air outlet 413 is provided, so that the water mist will not enter the air outlet 413.

[0060] In a preferred embodiment of the present utility model, an L-shaped reinforcing rib 12 connected to the horizontal step surface 411 and the vertical step surface 412 of the step 41 is provided at the air outlet 413. Since the water tank 2 and the air outlet pipe 4 are integrally formed of polypropylene material, by providing the L-shaped reinforcing rib 12, after the water tank 2 is demolded, the air outlet 413 of the air outlet pipe 4 will not be deformed due to the polypropylene material not being cooled and shaped yet, which is beneficial to improving the qualified rate of the water tank 2.

[0061] In the top-water adding humidifier provided by the present utility model, a protective box 13 is further provided at the bottom of the water tank 2. The protective box 13 covers the atomizing sheet 6. A male connector 14 is provided at the bottom of one side of the protective box 13. The upper end of the male connector 14 has a terminal that can be electrically connected to the atomizing sheet 6 by means of a cable. The upper part of the base 1 has a receiving recess that cooperates with the protective box 13, and a female connector 15 is provided in the concave surface of the receiving recess. The water tank 2 is placed on the base 1, and the male connector 14 and the female connector 15 can be connected to realize the electrical connection between the atomizing sheet 6 and the atomizing circuit board 8. This connection method enables the water tank 2 to be independently separated from the base 1, facilitating the user to clean the water tank 2 alone.

[0062] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or any direct / indirect application in other related technical fields shall be included in the patent protection scope of the present utility model.
