Description

Technical Field

[0001] The utility model belongs to the technical field of humidifiers, and in particular relates to a humidifier capable of preventing water from overflowing. Background Art

[0002] As a product that increases the humidity in a space, a humidifier has a mist outlet channel connecting its atomization space and the outside world. The atomized water flows to the outside world through the mist outlet channel. However, if the humidifier is tipped over during use, the water inside it is easy to spill to the outside world through the mist outlet channel, causing inconvenience; if the humidifier is a heating humidifier, the water is at a high temperature and spills on the human body, causing scalding and harm to the user.

[0003] For this purpose, the prior art has a blocking structure set in the mist outlet channel. When the humidifier falls over, the blocking structure blocks the mist outlet channel to prevent water from flowing to the outside through the mist outlet channel. For example, US Patent US20070176306A1 discloses a safety device for a humidifier. The device sets a ball holder between the water tank and the nozzle, a ball is set on the ball holder, and a cushion made of silicon dioxide is installed on the periphery of the nozzle. When the humidifier falls over, water pushes the ball to move toward the cushion, and finally gets stuck on the cushion to block the nozzle, preventing the water in the water tank from overflowing. However, in actual use, since the water and the ball move together, before the ball completely blocks the nozzle, some water will still flow out of the nozzle faster than the ball, and the effect of preventing water from overflowing is poor.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] A humidifier that prevents water from overflowing, see Figure 1-Figure 2 , including a humidifier base 1, a cover body 2 covering the humidifier base 1, and an atomizing device 3.

[0036] In this embodiment, a buckle 21 is provided at the edge of the cover 2, and a rotation buckle position 11 cooperating with the buckle 21 is provided at the top of the humidifier base 1. When the cover 2 is covered on the humidifier base 1, the buckle 21 is locked in the rotation buckle position 11; the cover 2 is rotated, and the buckle 21 is screwed into the rotation buckle position 11, thereby fixing the cover 2 on the humidifier base 1. It can be understood that the rotation buckle position 11 can also be set on the cover 2, and the buckle 21 is set on the humidifier base 1.

[0037] An atomizing space is provided in the humidifier base 1, and an opening 22 is provided on the cover body 2, which is connected to the atomizing space of the humidifier base 1 to form a mist outlet channel 4. The atomizing device 3 is used to atomize the water in the atomizing space, and the atomized water flows to the outside through the mist outlet channel 4. In this embodiment, the atomizing device 3 is a heating component for heating water to evaporate, and the structure of the heating component adopts the existing heating structure, which will not be repeated here. In other embodiments, the atomizing device 3 can also be an ultrasonic generating device.

[0038] In this embodiment, see Figure 3 The humidifier also includes a blocking component 5, which includes a support 51, a valve body 52, a moving block 53 and an elastic member 54. Among them, the support 51 is fixed in the mist outlet channel 4, and the valve body 52 can be slidably arranged on the support 51 up and down to block the mist outlet channel 4; the moving block 53 is movably arranged above the valve body 52. ​​When the humidifier is in an upright state, the moving block 53 moves to press down the valve body 52 under the action of its own gravity, thereby opening the mist outlet channel 4, and the atomized water in the humidifier flows to the outside through the mist outlet channel 4. When the humidifier is tilted, the moving block 53 no longer presses the valve body 52, and the valve body 52 returns to the state of blocking the mist outlet channel 4 under the resetting action of the elastic member 54 (see the state diagram). Figure 4 ), at this time, the water in the humidifier is blocked inside and cannot flow to the outside through the mist outlet channel 4, so as to avoid water spilling to the outside and causing inconvenience to the user and also avoid causing harm to the user. When the above humidifier is tipped over, the force of the moving block 53 on the valve body 52 changes immediately, and the valve body 52 can block the mist outlet channel 4 in time under the action of the elastic member 54, effectively alleviating the problem in the prior art that some water still flows out when the humidifier is tipped over.

[0039] In this embodiment, a liquid holding part 12 is provided in the humidifier base 1, and the internal space of the liquid holding part 12 is an atomization space; the support 51 is installed in the liquid holding part 12, and accordingly, the valve body 52 and the elastic member 54 are also located in the liquid holding part 12. Since the space in the liquid holding part 12 is relatively large, installing the support 51 in the liquid holding part 12 facilitates maintenance of the support 51, the valve body 52, and the elastic member 54. For details, see Figure 2-Figure 3 The liquid holding part 12 is connected to a heat-insulating cover 6 having a first mist outlet 61. The heat-insulating cover 6 is used to separate the internal space of the liquid holding part 12 into a first space 121 located inside the liquid holding part 12 and a second space 122 located outside the liquid holding part 12. The first space 121 is an atomizing space. The atomizing device 3 only heats and atomizes the water in the first space 121. This improves the heating and atomizing efficiency of the water when the machine is just turned on, shortens the heating and atomizing time, and improves the use effect of the humidifier. The above-mentioned support 51 is fixed in the heat-insulating cover 6. Since the heat-insulating cover 6 is a structure relatively independent of the humidifier base 1 and the cover 2, and its size is relatively small, it is convenient to form a support 51 with a stable structure.

[0040] like Figure 2-Figure 3 As shown, the support 51 is specifically fixed to the first mist outlet 61 of the heat insulation cover 6. Since the cross-sectional size of the first mist outlet 61 is smaller than the cross-sectional size of the internal space of the heat insulation cover 6, fixing the support 51 to the first mist outlet 61 can just enable the valve body 52 to cooperate with the first mist outlet 61 and the internal space of the heat insulation cover 6. Specifically, when the humidifier is in an upright state, the valve body 52 extends into the heat insulation cover 6, and the first mist outlet 61 is in an open state. When the humidifier is tilted, the valve body 52 moves upward under the action of the elastic member 54 to block the first mist outlet 61, so that there is no need to set other sealing structures to cooperate with the valve body 52, and the structure is simple.

[0041] In other embodiments, the support 51 may also be fixed in the opening 22 of the cover body 2 .

[0042] In this embodiment, the opening 22 of the cover body 2 includes a mist inlet 221, an active cavity 222, and a second mist outlet 223 which are connected in sequence from bottom to top. The mist inlet 221 is connected to the atomization space, specifically connected to the first mist outlet 61 of the heat insulation cover 6, and the second mist outlet 223 is connected to the outside world. The movable block 53 is movably arranged in the active cavity 222. When the cover body 2 is covered on the humidifier base 1, the movable block 53 moves to the middle position at the bottom of the active cavity 222 under the action of its own gravity. This position is opposite to the valve body 52. ​​During the covering process, the movable block 53 presses down the valve body 52, and the valve body 52 moves downward to open the first mist outlet 61. When the humidifier is tilted, the movable block 53 moves sideways under the action of its own gravity and no longer presses down the valve body 52. ​​At this time, the valve body 52 moves upward under the action of the elastic member 54, thereby blocking the first mist outlet 61.

[0043] In this embodiment, if Figure 2-Figure 3 As shown, the wall surface of the movable chamber 222 is an arc surface or an inclined surface that gradually shrinks downward. With such an arrangement, when the humidifier is restored to an upright state, the moving block 53 can move along the arc surface or the inclined surface to above the valve body 52 .

[0044] Furthermore, in the height direction of the humidifier, the highest position of the valve body 52 does not exceed the center position of the moving block 53 in the upright state. In this way, when the humidifier is restored to the upright state, the moving block 53 can move smoothly to the top of the valve body 52, avoiding the valve body 52 from being stuck on the side of the valve body 52 and unable to press down the valve body 52 to open the mist outlet channel 4.

[0045] Furthermore, the moving block 53 is preferably a rolling ball, which makes the moving block 53 move more smoothly in the active cavity 222.

[0046] See also Figure 2-Figure 3 A limit plate 224 is provided in the active cavity 222, which can limit the movement range of the moving block 53 in the active cavity 222 and improve the user experience. Furthermore, a guide structure is formed in the active cavity 222 just above the space formed by the limit plate 224. The guide structure protrudes downward to guide the discharge of water vapor. In addition, the guide structure cooperates with the limit plate 224 to prevent the moving block 53 from moving out of the space of the limit plate 224.

[0047] In this embodiment, see Figure 2-Figure 3 The valve body 52 includes a valve stem 521 and a valve core 522 arranged on the valve stem. The valve stem 521 is slidably arranged on the support 51. In the upright state, the moving block 53 presses down the top of the valve stem 521. The valve core 522 is used to block the mist outlet channel 4 when the humidifier is tilted.

[0048] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
