Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, and particularly to a leak-proof humidifier. Background Art

[0002] Existing humidifiers generally include a water tank assembly and a base assembly. Among them, an atomizer is generally arranged on the base assembly, and a channel is arranged between the water tank assembly and the base assembly to enable the water in the water tank assembly to flow into the base assembly. A retaining rib is arranged inside the bottom of the water tank of the water tank assembly to divide the accommodation cavity between the base and the water tank assembly on the base surface into an inner water path and an outer water path. In order to achieve a good sealing effect, the outer peripheries of the water tank assembly and the base assembly are in full contact, and even a sealing ring is used for sealing. The gap between the retaining rib and the base surface is between 0.1 mm and 0.2 mm. During the process of the water tank getting wet or atomization, this small gap is also very easy to form a water film to seal it dead. Only a communication channel with a certain height is arranged between the inner water path and the outer water path so that the water falling from the water tank assembly into the outer water path can enter the inner water path for atomization. However, when the water inlet height exceeds the maximum height of the communication channel, the space above the outer water path is fully sealed at this time. When the water level continues to rise, the air in this accommodation space will be compressed, resulting in an increase in air pressure until the generated pressure difference is the same as the water pressure of the water tank. The water level of the outer water path will no longer be able to rise; but at this time, the surface air pressures in the inner water path and the water tank are both ambient air pressures, and the water pressure in the accommodation space is relatively large, which will cause the water level in the inner water path to continue to rise, and finally the machine will leak water from the air duct. Summary of the Utility Model

[0003] The utility model discloses a leak-proof humidifier, aiming to improve the problem that the existing humidifier is prone to water leakage during the water filling process.

[0004] The utility model adopts the following scheme:

[0005] A leak-proof humidifier includes a base assembly and a water tank assembly. A water storage cavity is formed between the base assembly and the water tank assembly. An inner water path communicated with an atomization assembly and an outer water path communicated with the water tank assembly are formed in the water storage cavity. A communication port is arranged between the inner water flow and the outer water path to communicate the outer water path with the inner water path. An air vent is arranged between the base assembly and the water tank assembly. The height position of the air vent is higher than the communication port and the highest water level in the water storage cavity, so that the surface air pressure of the outer water path is always kept consistent with the ambient air pressure when the water tank assembly fills water into the water storage cavity.

[0006] Further, the water tank assembly includes a water tank body, and the base assembly includes a base main body. A retaining rib is arranged on the bottom surface of the water tank body, and the retaining rib is adapted to divide the top surface of the base main body into the inner water path and the outer water path.

[0007] Further, a notch is formed at the bottom edge of the enclosure rib to form the communication port; the upper part of the enclosure rib is adapted to form the ventilation port with the base body.

[0008] Further, a gas pipeline is formed on the base body, a connection part is formed between the gas pipeline and the edge of the base body, and the ventilation port is formed between the enclosure rib and the top surface of the connection part.

[0009] Further, the enclosure rib is formed with a U-shaped opening adapted to cooperate with the connection part, and the ventilation port with an opening height greater than 2 mm is formed between the highest point of the U-shaped opening and the top surface of the connection part.

[0010] Further, a float assembly is arranged on the base assembly, and the float assembly is adapted to control the communication between the base assembly and the water tank assembly according to the level of the liquid level entering the water storage chamber.

[0011] Beneficial effects:

[0012] In this solution, a ventilation port higher than the communication port and the highest water level of the water storage chamber is arranged between the inner peripheral waterway and the outer peripheral waterway, so as to keep the air pressure on the upper surface of the outer peripheral waterway the same as the ambient atmosphere when filling water into the water storage chamber, that is, to keep the air pressure on the surfaces of the inner peripheral waterway and the outer peripheral waterway the same, so as to prevent the liquid level in the inner peripheral waterway from continuously rising due to the water pressure of the outer peripheral waterway being greater than that of the inner peripheral waterway and leaking from the gas pipeline. Through this solution, the problem of water leakage of the humidifier can be effectively prevented. Description of the drawings

[0018] In combination withFigures 1 to 4 As shown in the figure, this embodiment provides a leak-proof humidifier, which includes a base assembly and a water tank assembly. A water storage cavity 3 is formed between the base assembly and the water tank assembly. An inner peripheral waterway communicating with the atomization assembly 5 and an outer peripheral waterway communicating with the water tank assembly are formed in the water storage cavity 3. A communication port 13 is provided between the inner peripheral water flow and the outer peripheral waterway to communicate the outer peripheral waterway with the inner peripheral waterway. An air vent 14 is provided between the base assembly and the water tank assembly. The air vent 14 is higher than the communication port 13 and the highest water level in the water storage cavity 3, so that when the water tank assembly injects water into the water storage cavity 3, the surface air pressure of the outer peripheral waterway is always kept consistent with the ambient air pressure, thereby preventing the surface air pressure of the outer peripheral waterway from being too high and raising the liquid level of the inner peripheral waterway to the air outlet of the gas pipeline, resulting in water leakage.

[0019] In this embodiment, the humidifier includes a base assembly and a water tank assembly. The base assembly includes a base main body 2, a fan assembly 4, an atomization assembly 5, and a float assembly 6. The upper surface of the base main body 2 forms a bowl-shaped chamber to cooperate with the water tank assembly to form a water storage cavity 3. A gas pipeline 21 is formed on the base main body 2, and a connection part 22 is formed between the gas pipeline 21 and the edge of the base main body 2. The fan assembly 4 is arranged at the bottom of the gas pipeline 21.

[0020] Combined with Figures 2 to 4 As shown in the figure, the water tank assembly includes a water tank body 1. A surrounding rib 11 is provided on the bottom surface of the water tank body 1. The surrounding rib 11 forms a U-shaped opening 12 adapted to cooperate with the connection part 22. When the water tank body 1 is installed on the base main body 2, the U-shaped opening 12 of the surrounding rib 11 is inserted into the connection part 22, and the upper surface of the base main body 2 is divided into the inner peripheral waterway and the outer peripheral waterway. At this time, the surrounding rib 11 can be in direct contact with the base main body 2 or have a gap of 0.1-0.2 mm. A notch is formed at the bottom edge of the surrounding rib 11 to form the communication port 13 with the surface of the base main body, so that the water in the outer peripheral waterway can enter the inner peripheral waterway through the communication port 13. The upper part of the surrounding rib 11 is adapted to form the air vent 14 with the base main body 2; specifically, the air vent 14 can be formed between the surrounding rib 11 and the top surface of the connection part 22. For example, a gap with an opening height greater than 2 mm is formed between the highest point of the U-shaped opening 12 and the top surface of the connection part 22, and the gap and the air vent 14. It should be noted that the opening height of the air vent 14 here needs to be greater than 2 mm to prevent the formation of a water film seal. In addition, in other embodiments, the position of the air vent 14 can also be formed at other positions of the surrounding rib 11, or formed at other positions of the inner peripheral waterway and the outer peripheral waterway, and its position height should be higher than the position of the air vent 14 and the highest water level of the water storage cavity 3, so as to prevent the air vent 14 from being sealed.

[0021] In this embodiment, the atomization assembly 5 and the gas pipeline are both located within the inner peripheral water path and are surrounded by the retaining rib 11. The gas pipeline is in communication with the atomization assembly 5 and is connected to the mist outlet. A float assembly 6 is provided on the base assembly. The float assembly 6 is adapted to control the communication between the base assembly and the water tank assembly according to the level of the liquid level entering the water storage chamber 3. The structure of the float assembly 6 here is prior art and will not be elaborated. The opening and closing of the water inlet passage between the water tank body 1 and the water storage chamber 3 can be controlled by the float assembly 6, thereby controlling the highest water level of the water storage chamber 3. A wind baffle is provided at the opening of the gas pipeline, and a top block is provided at the bottom of the water tank body 1. When the water tank body 1 is installed on the base body 2, the top block can push open the wind baffle to conduct the air path.

[0022] In the solution of this embodiment, a ventilation port 14 is provided between the inner peripheral water path and the outer peripheral water path, and the position of the ventilation port 14 is higher than the communication port 13 and the highest water level of the water storage chamber 3, so as to keep the air pressure on the upper surface of the outer peripheral water path the same as the ambient atmosphere when filling water into the water storage chamber 3, that is, to keep the air pressure on the surfaces of the inner peripheral water path and the outer peripheral water path the same, so as to prevent the liquid level in the inner peripheral water path from continuously rising and leaking from the gas pipeline 21 due to the water pressure of the outer peripheral water path being greater than that of the inner peripheral water path, and the problem of water leakage of the humidifier can be effectively prevented.
