Referring to fig. 1, a humidifier provided in an embodiment of the present application includes a housing 10 and an electrically controlled valve assembly 20.

Wherein, the shell 10 plays a role of bearing the water body, the electric control valve assembly 20 and other elements, and the electric control valve assembly 20 is used for realizing the automatic circulation and atomization of the water body.

Specifically, the housing 10 includes a water storage chamber 10a, an atomizing chamber 10b, and a receiving chamber 10c sequentially disposed from top to bottom, the water storage chamber 10a is communicated with the atomizing chamber 10b, and the atomizing chamber 10b is communicated with the receiving chamber 10c. Here, it should be explained that, after the housing 10 is manufactured and molded, the water storage chamber 10a and the atomizing chamber 10b are in a normally open state so that water can enter the atomizing chamber 10b from the water storage chamber 10a; the atomizing chamber 10b and the accommodating chamber 10c are in a normally open state to satisfy the respective component arrangement.

The electric control valve assembly 20 comprises an electric control main body 21 arranged in the accommodating cavity 10c, an ejector 22 for blocking the communication position of the atomizing cavity 10b and the accommodating cavity 10c in real time, and a blocking piece 23 for realizing the communication or closing of the water storage cavity 10a and the atomizing cavity 10 b. Here, the electric control main body 21 needs to supply power during operation, so the electric control main body 21 is arranged in the accommodating space in the sewage state, so that the electric control main body 21 can work normally. The ejector 22 seals the communicating atomizing chamber 10b and the accommodating chamber 10c, so that the accommodating chamber 10c is in a liquid-free state. Simultaneously, under the up-and-down pushing action of the pushing piece 22, the blocking piece 23 can realize the communication or the closing of the water storage cavity 10a and the atomization cavity 10 b.

Specifically, when the electric control main body 21 is electrified, the ejector 22 is pushed to lift up, and the blocking piece 23 is driven to lift up, so that the water storage cavity 10a and the atomization cavity 10b are in a communication state, and then water can enter the atomization cavity 10b for atomization; and when the electric control main body 21 is powered off, the ejector 22 and the blocking piece 23 move downwards to reset under the action of water pressure, so that the water storage cavity 10a and the atomizing cavity 10b are in a non-communication state.

The humidifier provided by the utility model divides a housing 10 into a water storage cavity 10a, an atomization cavity 10b and a containing cavity 10c. Under the blocking action of the ejector 22, the atomizing chamber 10b and the accommodating chamber 10c are in a real-time non-communication state, i.e., the electric control main body 21 requiring energization is disposed in the accommodating chamber 10c. Specifically, when the electric control main body 21 is in an electrified state, the ejector 22 lifts to drive the blocking piece 23 to lift, at this time, the water storage cavity 10a is communicated with the atomization cavity 10b, water in the water storage cavity 10a enters the atomization cavity 10b, and atomization is carried out in the atomization cavity 10 b; when the electric control main body 21 is in the power-off state, under the action of water pressure, the blocking piece 23 is reset, and the ejector piece 22 is driven to be reset, at the moment, the water storage cavity 10a and the atomization cavity 10b are not communicated with each other, and water in the water storage cavity 10a does not enter the atomization cavity 10 b. Thus, whether or not water enters the atomizing chamber 10b, the accommodating chamber 10c can be kept dry all the time, so that the failure probability of the electric control main body 21 caused by contacting the water is reduced, and the failure rate of the electric control main body 21 is further reduced.

Referring to fig. 1 and 4, in one embodiment, a first opening is formed in the housing 10, the atomizing chamber 10b is communicated with the accommodating chamber 10c through the first opening, the ejector 22 includes a flexible portion 221 for blocking the first opening, and an ejector portion 222 disposed on the flexible portion 221, and the ejector portion 222 is driven by the electric control main body 21 to perform an upward or downward movement.

It will be appreciated that in order to meet both the occlusion and ejection requirements, the ejector 22 should be somewhat flexible. Therefore, the atomizing chamber 10b also forms water, and thus, the flexible portion 221 is pressed against the periphery of the first opening by the water pressure to block it. Here, the flexible portion 221 may be made of a material such as silicone rubber or rubber. Meanwhile, the pushing portion 222 also moves up and down along with the flexible portion 221, which is required that the flexible portion 221 can keep blocking the first opening during the up and down process of the pushing portion 222.

Optionally, the flexible portion 221 and the pushing portion 222 are integrally formed, the flexible portion 221 is a circular sheet structure, the pushing portion 222 is a columnar structure disposed in the middle of the circular sheet structure, and the columnar structure is disposed through the circular sheet structure, so that the circular sheet structure can meet the stroke requirement required by up-and-down fluctuation of the columnar structure.

Referring to fig. 1 and 3, in one embodiment, the humidifier further includes a fixing plate 30, and the fixing plate 30 is disposed in the accommodating cavity 10c and is used to press the edge of the flexible portion 221.

As can be appreciated, the fixing plate 30 is used to fix the edge of the flexible portion 221, so as to avoid a liquid leakage gap between the edge of the flexible portion 221 and the inner wall of the housing 10.

Referring to fig. 1, in one embodiment, the pushing portion 222 at least partially extends into the accommodating cavity 10c and is used for abutting against the electronic control main body 21.

As can be appreciated, since the electronic control body 21 is disposed within the housing cavity 10c, the ejector 222 extends at least partially into the housing cavity 10c in order to be able to form a connection with the electronic control body 21.

Here, the shape of the portion of the push-up portion 222 protruding into the accommodation chamber 10c and the connection relationship with the electronic control main body 21 are not limited.

Alternatively, the push-up part 222 has no connection relation with the electric control main body 21, and force transmission is realized between the push-up part and the electric control main body by a propping mode.

Optionally, the pushing portion 222 is hinged to the electric control main body 21, and the electric control main body 21 can synchronously drive the pushing portion 222 to move up and down.

Referring to fig. 1, 3 and 5, in one embodiment, the housing 10 is provided with a second opening, the water storage chamber 10a is communicated with the atomization chamber 10b through the second opening, the plugging member 23 includes a rod 231 and a plugging head 232 disposed on the rod 231, the rod 231 is used for abutting against the ejector 22, and the plugging head 232 is used for plugging or opening the second through hole.

It can be appreciated that the rod 231 of the blocking member 23 is connected to the ejector member 22 in an abutting manner, and can drive the rod 231 to move up and down along the vertical direction. The blocking head 232 is driven by the rod body 231 to move up and down, so as to realize the opening and closing of the second opening.

Specifically, referring to fig. 1 and 5, in one embodiment, rod 231 includes first and second axially disposed rod segments 2311, 2312, the first rod segment 2311 having a larger diameter than the second rod segment 2312.

It will be appreciated that the first stem segment 2311 is configured to abut the ejector 22, and that a larger diameter increases the contact area with the ejector 22, thereby improving the accuracy of the ejector process. Second pole segment 2312 is used to connect to stopper 232. Optionally, occlusion head 232 is flexible and can be swaged into second stem segment 2312.

Referring to fig. 1 and 6, in one embodiment, a plug 232 is disposed in the water storage chamber 10a, the plug 232 having a plug taper 232a for plugging the second opening.

It can be appreciated that the plugging head 232 has a shape structure with a large top and a small bottom, so that the plugging head 232 can better plug the second opening under the action of water pressure, and the plugging effect of the plugging conical surface 232a is better. At the same time, the plugging head 232 can be reset by water pressure.

Referring to fig. 1 and 3, in one embodiment, the electric control main body 21 includes a solenoid valve body 211, a solenoid valve pull rod 212 magnetically connected to the solenoid valve body 211, a rocker 213 with one end hinged to the solenoid valve pull rod 212, and a base 214 hinged to the middle of the rocker 213, where the other end of the rocker 213 is used to abut against the ejector 22.

It can be understood that the electromagnetic valve body 211 forms a magnetic field in the energized state, and does not have a magnetic field in the de-energized state, and drives the electromagnetic valve pull rod 212 to move up and down under the action of magnetic force, so as to drive the rocker 213 to swing around the base 214, and when the rocker 213 swings around the base 214, the other end of the rocker 213 abuts against the ejector 22. The ejector 22 can drive the plugging piece 23 to lift up, so that the water storage cavity 10a is communicated with the atomization cavity 10b, and water is supplied to the atomization cavity 10 b.

Meanwhile, no matter how the atomizing cavity 10b supplies water, the ejector 22 always plugs the first opening, and water in the atomizing cavity 10b cannot enter the accommodating cavity 10c, so that the whole electric control main body 21 cannot contact the water, and the use safety of the electric control main body 21 in the electrified state is improved.

Referring to fig. 1 and 2, in one embodiment, a housing 10 includes a first housing 11 and a second housing 12 sequentially stacked from top to bottom, the first housing 11 includes a main body 111 having an open end and a cover 12 covering the main body 111, and the main body 111 and the cover 12 enclose a water storage chamber 10a; the second housing 12 has an atomizing chamber 10b and a receiving chamber 10c.
