Description

Technical Field

[0001] The present invention relates to the technical field of humidifiers, and in particular to a water ingress prevention structure for an air outlet of a pop-up humidifier. Background Art

[0002] With the improvement of living conditions, people have higher and higher requirements for the comfort of their living environment. In northern regions and places where air conditioners are used for a long time, the air is relatively dry. Humidifiers can vibrate water into mist and blow it into the air through the blower in the humidifier, effectively increasing the air humidity and improving the comfort of the living environment.

[0003] Traditional humidifiers currently on the market generally include a housing, water tank, electronic control assembly, atomizer, atomization chamber, mist cover, and fan assembly. The water tank assembly, atomizer assembly, and fan assembly are located inside the housing assembly, with the mist cover located at the top. The electronic control assembly can be used to adjust the size of the mist, the humidification time, and the start and stop of the motor. The water tank assembly is connected to the atomizer assembly, and water flows from the water tank to the atomizer assembly. The atomizer oscillates at high frequency to atomize the water. The fan assembly blows air to spray the mist from the air cover assembly out of the machine, realizing the humidification function. The fan assembly generally consists of a fan and an air outlet assembly. The air outlet assembly is generally located on the base of the humidifier, below the water tank assembly, and is used to blow the atomized water vapor toward the mist outlet of the mist cover to spray water mist. Since the air outlet assembly is located on the lower side of the water tank and is directly connected to the fan, when the humidifier is used for a long time, a certain amount of water droplets will accumulate at the bottom of the water tank. Since there is no longitudinal and transverse shielding structure at the air outlet of the traditional humidifier, the accumulated water droplets can easily fall into the air outlet and then enter the fan, causing the motor to short circuit and burn.

[0004] To solve this problem, humidifiers on the market have made certain improvements to the air outlet structure, setting the top of the opening in an arc shape and extending it outward for a certain distance, and setting horizontal cross ribs on the side walls of the opening to prevent water droplets from falling into the air outlet along the arc-shaped side walls. This structure is only applicable to traditional humidifiers with an integrated water tank and base, where water is added from the top. For humidifiers with detachable water tanks, during the disassembly and assembly of the water tank, due to operational shaking, water droplets at the bottom of the water tank may still fall into the air outlet, causing safety accidents. In addition, in order to enhance the sealing of the air outlet, some humidifiers on the market often have a manually operated capping structure at the air outlet, but the manually operated capping structure is not simple enough, which affects the user experience.

[0005] Therefore, the structure of the air outlet needs to be further improved, and it must be able to take into account both waterproof and easy operation functions. When the water tank is filled with water, the air outlet is closed. When the water is added and the system is working normally, the air outlet remains open normally without the need for additional operation. Summary of the Invention

[0006] In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a waterproof device capable of covering the air outlet of the humidifier, so that the air outlet remains closed when water is added to the water tank of the humidifier.

[0007] In order to solve the above technical problems, the present invention provides a waterproof structure for the air outlet of a pop-up humidifier, comprising a base, a fan and an air outlet pipe arranged on the base, the fan being installed in the base and corresponding to the position of the air outlet pipe, the air outlet pipe having an air outlet, and also comprising a spring and a protective cover fixed on the air outlet pipe, the protective cover being able to move up and down with the air outlet pipe, the spring being arranged between the protective cover and the air outlet pipe, the spring lifting the protective cover and blocking the air outlet, when the humidifier is working normally, the spring will be subjected to downward pressure from the bottom of the water tank, driving the protective cover to move downward, the air outlet being open, and normal ventilation, through this technical solution, when the water tank is lifted, the spring is in a state of not being squeezed, and the spring returns to its original state under the action of the restoring force, the top of the protective cover and the top of the air outlet pipe are restored to be combined and are in a sealed state.

[0008] Furthermore, the protective cover includes a cover body, and a step portion is provided on the outer wall of the cover body. The radius of the cover body on the lower side of the step portion is larger than the radius of the cover body on the upper side. The cover body can be mounted on the air outlet pipe and can be displaced up and down under the elastic force of the spring, thereby achieving the opening and closing of the air outlet.

[0009] Furthermore, the bottom of the spring abuts against the bottom of the air outlet pipe, and the top abuts against the top of the step. The step acts as a limiter for the spring, so that when the cover moves downward, the spring is squeezed by the step, generating an elastic force. When there is no pressure, the spring will not pop out due to excessive elastic force when it returns.

[0010] Furthermore, a side plate is vertically provided on the side wall of the cover body. When the humidifier is in working state, the side plate is against the bottom of the humidifier, so that the cover body of the protective cover is subjected to downward pressure, so that the air outlet of the air outlet pipe is in an open state and air is discharged normally.

[0011] Furthermore, a stop plate is provided along the edge of the inner wall of the cover, and the stop plate extends toward the center of the cover. The stop plate is in the shape of two steps, and the bottom of the stop plate extends to a greater extent than the top of the stop plate.

[0012] Furthermore, the top of the stopper plate engages with the air outlet, while the bottom of the stopper plate contacts the air outlet. When the water tank is lifted, the protective cover is not subjected to the pressure of the water tank, and the upper portion of the stopper plate can cooperate to cover the air outlet at the top of the air outlet pipe. The top of the cover body tightly engages with the top of the air outlet pipe to achieve a sealed cover for the air outlet. At the same time, since the bottom portion of the stopper plate extends further than the top portion, it can contact the top of the air outlet pipe, acting as a position limiter for the cover body. When the cover body is lifted up by the spring, it prevents the cover body from being lifted up due to excessive elastic force.

[0013] The invention also provides a humidifier including the anti-water inflow structure, including a water tank, the atomization chamber is arranged on the bottom cover, the water tank is detachably installed on the base, and the bottom cover of the water tank is provided with an interference structure that cooperates with the protective cover.

[0014] Furthermore, the bottom cover is provided with an atomizing chamber, and the abutting connection comprises a partition provided in the atomizing chamber, and the side panels abutting against the partition when the water tank is fixed to the base. This structure allows the humidifier to operate normally when the bottom of the water tank abuts against the partition on the protective cover, squeezing the protective cover downward, driving the protective cover downward, and the cover portion moves downward, leaving the air outlet partially open and allowing normal air flow. When the water tank is lifted to add water, the protective cover is no longer under pressure and is pushed upward by the restoring force of the spring to cover the air outlet.

[0015] Furthermore, the pressing structure is in a cross pressing shape. The cross pressing structure enables the water tank to exert positive downward pressure during installation, pressing the protective cover downward, so that the gap at the top of the air outlet pipe is opened, and normal air outlet is achieved.

[0016] The interference structure includes a partition plate arranged in the atomization chamber and a side plate arranged on the side wall of the protective sleeve. The interference structure is in a cross-pressure shape.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the waterproof structure of the air outlet of the humidifier provided by the present invention is a protective cover that can be displaced relative to the air outlet pipe is set on the air outlet pipe, and a spring is set in the protective cover, and an interference structure is set on the protective cover and the bottom cover of the water tank, and the up and down movement of the protective cover can be controlled by the installation state of the water tank. When the water tank is filled with water and installed on the base, the bottom cover of the water tank applies downward pressure on the protective cover, causing the protective cover to move downward, the air outlet of the air outlet pipe is opened, and air is discharged normally. When the water tank is detached from the base to add water, the protective cover is not under pressure, and the restoring force of the spring will The protective cover is lifted up and the air outlet is sealed again, which effectively prevents water droplets at the bottom of the water tank from falling into the air outlet and burning the fan. The present invention can automatically realize the automatic opening and closing of the air outlet according to the installation status of the water tank. Without additional operation, the opening and closing of the air outlet can be controlled according to the use status of the humidifier. When it is lifted to add water, the air outlet remains sealed to prevent water, dust and other impurities from falling into the air outlet, causing the risk of water ingress or blockage of internal components, affecting the normal operation of the humidifier. After water adding is completed, the air outlet can be kept open when the humidifier is working normally to achieve normal blowing and spraying. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific embodiments of the present invention are further described below with reference to the accompanying drawings:

[0024] See also Figures 1 to 5 The present invention discloses a waterproof structure for a humidifier's air outlet, applicable to humidifiers with a detachable water tank and independent water supply. The humidifier comprises a top cover 1, a water tank 2, and a base 4. The water tank 2 is mounted on top of the base 4. To add water, the water tank is pulled upward, flipped over, and water is added through the water inlet 212 at the bottom of the water tank 2. A fan assembly is disposed within the base 4, and an air outlet duct 314 is disposed above the fan assembly. The top of the air outlet duct extends through the base 4. Under the action of the fan assembly, atomized water vapor passes through the air outlet duct and is finally sprayed out from the spray port in the top cover 1.

[0025] The waterproof structure includes a protective cover 31 and a spring 313. The protective cover 31 is sleeved on the air outlet pipe 314. The protective cover includes a cover body 311. The cover body is a hollow sleeve, including but not limited to a cylindrical, elongated, or prismatic shape. The outer wall of the cover body 311 is provided with a step portion 311c. The radius of the cover body of the lower part of the step portion 311c is larger than that of the upper part. The spring 313 is provided between the protective cover 31 and the air outlet pipe 314. The top of the spring 313 conflicts with the step portion 311c. The protective cover 31 can move up and down relative to the air outlet pipe 314 under the elastic force of the spring 313. The side wall of the air outlet pipe is provided with an air outlet 31 2, is a U-shaped notch, the protective cover 31 also includes a cover body 311, and a stop plate 311a is provided on the top of the cover body 311. The stop plate extends toward the center of the circle along the edge of the top of the cover body 311, and the stop plate 311a is stepped, consisting of an upper and lower layer, and the lower layer extends to a greater extent toward the center of the circle than the upper layer. In the initial state, the upper layer of the stop plate 311a can completely fit the arc notch formed by the U-shaped air outlet 312 at the top of the air outlet pipe 314 to achieve a cover, and the lower layer is against the top of the air outlet pipe. A side plate 311b is provided on the side wall of the cover body 311, and a side plate 311b is also provided on the side wall of the cover body 311. The atomizing chamber 211 of the bottom cover of the humidifier is provided with a partition 211a, which is arranged in the atomizing chamber 211 formed by the U-shaped groove of the bottom cover 21 of the humidifier water tank. When the water tank is installed on the base 4, the partition 211 and the side plate 311b cross and press each other to form a resistance structure. When the water tank 2 is filled with water and installed, the partition 211a on the bottom cover 211 of the water tank cross and press the side plate 311b of the cover body 311, driving the protective cover 31 to move downward, and the air outlet 312 at the top of the air outlet pipe 314 is opened. The air flow can be discharged through the air outlet 312, blowing the atomized water in the atomizing chamber 211. The spring 313 is in a state of not being squeezed, and the spring 313 returns to its original shape under the action of the restoring force, and the top of the protective cover 31, the stop plate of the cover body and the top of the air outlet 312 are restored to the closed state. Through this technical solution, the air outlet 312 is closed when the water tank is added with water, and the water on the outer wall of the water tank 2 is prevented from falling into the fan and other devices in the base through the air outlet 312 during installation, causing damage. In addition, the air outlet 312 can also be prevented from being blocked by dust. After the water is added and the water tank is assembled, the air outlet 312 is opened normally to ensure the normal ventilation of the humidifier.

[0026] Preferably, a stop plate 311a is provided along the edge of the inner wall of the cover 311. The stop plate 311a extends toward the center of the cover 311 and is stepped in two layers. The bottom of the stop plate 311a extends further than the top of the stop plate 311a. The top of the stop plate 311a engages with the air outlet 312, while the bottom of the stop plate 311a abuts against the air outlet 312. When the water tank is lifted, the protective cover 31 is not subjected to the pressure of the water tank, and the upper part of the stop plate 311a can cooperate to cover the air outlet 312 at the top of the air outlet pipe 314. The top of the cover body 311 is tightly connected with the top of the air outlet pipe 314 to achieve the sealing of the air outlet 312. At the same time, since the bottom of the stop plate 311a extends further than the top, it can conflict with the top of the air outlet pipe 314, playing a role in limiting the cover body 311. When the cover body 311 is lifted up by the spring, it can prevent the cover body 311 from being pushed up due to excessive elastic force.

[0027] Preferably, the stop plate 311a of the cover body 311 is stepped, and its lower layer extends toward the center of the circle to a greater extent than the upper layer. When the water tank 2 is lifted and the side plate 311b is not under pressure, the spring 313 pushes the protective cover 31 upward under the action of the restoring force. The lower layer of the stop plate 311a can rest against the top of the air outlet pipe 314 to prevent the cover body 311 from being pushed away due to the excessive restoring force of the spring 313.

[0028] Preferably, the protective cover 31 also includes a cover body 311, and the outer wall of the cover body 311 is provided with a step portion 311c. The radius of the cover body 311 on the lower side of the step portion 311c is larger than the radius of the cover body 311 on the upper side. The cover body 311 can be mounted on the air outlet pipe and achieve up and down displacement under the elastic force of the spring 313, thereby achieving the opening and closing of the air outlet 312.

[0029] Preferably, the bottom of the spring 313 abuts against the bottom of the air outlet duct 314, and the top abuts against the top of the step 311c. The step 311c acts as a limiter for the spring 313, so that when the cover 311 moves downward, the spring 313 is squeezed by the step 311c, generating an elastic force. When there is no pressure, the spring 313 will not pop out due to excessive elastic force when it returns.

[0030] Preferably, a side panel 311b is vertically provided on the side wall of the cover body 311. When the humidifier is in working state, the side panel 311b is against the bottom of the humidifier, so that the cover body 311 of the protective cover 31 is subjected to downward pressure, so that the air outlet 312 of the air outlet pipe 314 is in an open state and air is discharged normally.

[0031] The invention also provides a humidifier including the anti-water inflow structure, including a water tank 2, a bottom cover 21, and a base 4. The water tank 2 is detachably mounted on the base 4 through the bottom cover 21. The bottom cover is provided with an atomization chamber 211. An interference structure cooperating with the protective cover 31 is provided between the bottom cover 4 and the protective cover 31.

[0032] Furthermore, the interference structure includes a partition 211a provided in the atomizing chamber, and a side plate 311b that presses against the partition 211a when the water tank 2 is fixed to the base 4. This structure allows the humidifier to operate normally when the bottom of the water tank 2 presses against the partition 211a on the protective cover 31, squeezing the protective cover 31 downward, driving the protective cover 31 downward, and the stop plate 311a at the top of the cover body 311 moves downward, partially opening the air outlet 312 and allowing normal air discharge. When the water tank is lifted to add water, the protective cover 31 is no longer under pressure and is pushed upward to cover the air outlet 312 under the restoring force of the spring 313.

[0033] Furthermore, the cross-pressing structure can make the water tank 2 exert positive downward pressure during installation, pressing the protective cover 31 downward, so that the gap at the top of the air outlet pipe 314 is opened, and normal air outlet is achieved.
