Description

Technical Field

[0001] This utility model relates to a ventilator water tank and belongs to the field of ventilator technology. Background Technology

[0002] To improve the comfort of ventilators, they are usually equipped with a water tank to increase the humidity of the inhaled air. The water tank is designed to prevent water from overflowing into the air intake or exhaust channels; in addition, the inside of the water tank needs to be cleaned regularly to keep it clean and prevent the air from being contaminated. Utility Model Content

[0003] To prevent water from overflowing into the air intake channel and to improve the ease of cleaning, this utility model provides a ventilator water tank, the specific technical solution of which is as follows.

[0004] A ventilator water tank includes a water tank upper cover and a water tank lower cover, the upper cover and the lower cover forming an inner cavity of the water tank. The upper cover is characterized in that an air inlet channel and an air outlet channel are provided on the upper cover. The air outlet end of the air inlet channel is detachably provided with a baffle cap, and the side wall of the baffle cap has an air outlet. The air inlet of the air outlet channel is located away from the air inlet channel.

[0005] By adopting the above technical solution, a baffle cap is installed at the air outlet end of the air inlet channel, which can control the shape (state) of the air entering the water and prevent the formation of huge air bubbles in the water tank, causing violent fluctuations on the water surface. This not only prevents water from overflowing into the air inlet channel, but also helps to prevent water from overflowing into the air outlet channel. At the same time, the detachable baffle cap is easy to remove and clean regularly, which helps to maintain the cleanliness of the water tank.

[0006] Furthermore, the side wall of the baffle near the air outlet channel does not have an air outlet. This arrangement ensures that the air outlet of the baffle is far from the air inlet of the air outlet channel, thus effectively and reliably increasing the humidity of the air.

[0007] Furthermore, the top plate of the baffle has a protrusion facing the outlet end of the air intake channel. The top plate of the baffle is the wall furthest from the outlet end of the air intake channel. By providing the protrusion, air can be effectively guided out of the outlet, avoiding turbulence inside the baffle.

[0008] Furthermore, the baffle cap can be detachably fixed to the air outlet end of the air intake channel by means of a snap-fit ​​mechanism.

[0009] Furthermore, the stop cap is made of silicone. Silicone stop caps are easy to manufacture, assemble, and disassemble, and are convenient to use.

[0010] Furthermore, a sealing strip is provided between the upper cover and the lower cover of the water tank. The sealing strip is used to maintain the airtightness of the water tank and prevent leakage.

[0011] Furthermore, the upper cover of the water tank is hinged to the lower cover of the water tank. This arrangement facilitates opening the upper cover of the water tank for adding water and cleaning.

[0012] Compared with the prior art, this utility model has a baffle cap at the air outlet of the air inlet channel, which can prevent liquid from overflowing into the inside or outside of the ventilator. The baffle cap is removable and easy to clean, which helps to keep the water tank clean. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] See Figures 1-4 A ventilator water tank includes a water tank upper cover 1 and a water tank lower cover 2, which form the inner cavity of the water tank. The water tank upper cover 1 is provided with an air inlet channel 3 and an air outlet channel 4. A detachable baffle 5 is provided at the air outlet end of the air inlet channel 3, and an air outlet 5.1 is located on the side wall of the baffle 5. The air inlet 4.1 of the air outlet channel 4 is located away from the air inlet channel 3. The air outlet channels 4 are all horizontally arranged, while the air inlet channels 3 are inclined in the horizontal direction close to the air outlet channels 4, with the air outlet end located close to the center of the water tank. This arrangement ensures that the gas entering the water tank is close to the center, increasing the humidification area and improving humidification efficiency.

[0020] like Figure 3 As shown, the side wall 5.3 of the baffle 5 near the air outlet 4 does not have an air outlet 5.1. The other three side walls 5.3 of the baffle 5 all have air outlets 5.1. Those skilled in the art will understand that the baffle 5... Figure 4The middle part has a cuboid structure, and the baffle 5 can also be set as a hemispherical structure. In short, the air outlet 5.1 of the baffle 5 is set away from the air outlet channel 4, which helps to increase the distance between the air outlet 5.1 and the air inlet 4.1, and can reliably increase the humidity of the air.

[0021] To better guide air from the outlet 5.1 into the water, the top plate 5.4 of the baffle 5 has a protrusion 5.2 facing the outlet end of the air intake channel 3. The top plate 5.4 of the baffle 5 is the wall furthest from the outlet end of the air intake channel 3. By setting the protrusion 5.2, air can be effectively guided out of the outlet 5.1, avoiding turbulence inside the baffle 5.

[0022] The baffle cap 5 can be detachably fixed to the air outlet end of the air intake channel 3 by snap-fit. Preferably, the baffle cap 5 is made of silicone material, which is easy to manufacture, assemble and disassemble, and convenient to use.

[0023] A sealing strip 6 is installed between the upper cover 1 and the lower cover 2 of the water tank. The sealing strip 6 is used to maintain the airtightness of the water tank and prevent water leakage. The upper cover 1 is hinged to the lower cover 2, which makes it easy to open the upper cover 1 to add water and clean the water tank.

[0024] When the water tank is in use, the water level inside the water tank is lower than the air outlet 5.1 of the baffle 5. There is space between the water level and the water tank cover 1 to accommodate air flow. The air discharged by the ventilator's fan enters the air intake channel 3, and then the air enters the space above the water level through the air outlet 5.1 of the baffle 5. The air, carrying water vapor, enters the air outlet channel 4 from the air inlet 4.1 and is finally discharged to the user end of the ventilator. When the user uses the ventilator, they can inhale humid air, which increases comfort.

[0025] In this embodiment, a baffle 5 is provided at the air outlet end of the air inlet channel 3, which can prevent water from overflowing into the air inlet channel 3 and also helps to prevent water from overflowing into the air outlet channel 4; at the same time, the detachable baffle 5 is easy to remove and clean regularly, which helps to keep the water tank clean.

[0026] The embodiments of the present invention have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention is not limited to the specific embodiments described above; these embodiments are merely illustrative and not limiting. Those skilled in the art, under the guidance of the present invention, can make many modifications without departing from the spirit and scope of the claims, and all such modifications fall within the protection scope of the present invention.
