Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, and more specifically, to a flip-type exhaust device. Background Technology

[0002] A humidifier is a household appliance that increases the humidity in a room. Humidifiers can humidify a specific room or be connected to a boiler or central air conditioning system to humidify the entire building.

[0003] Traditional solutions typically have the following shortcomings:

[0004] Mechanical valve regulation: Commonly found in humidifiers with independent adjustment knobs. Users need to manually rotate the valve to control the steam flow to different outlets. This method is relatively cumbersome, and the internal structure of the valve (such as the valve core and sealing ring) is prone to wear, jamming, or aging under long-term high temperature and high humidity conditions, leading to sealing failure, steam leakage, or irregular regulation, affecting user experience and product lifespan.

[0005] Snap-on / Limit-type reversing: Some designs force the steam passage to change through physical snap-on or limit structures. This type of structure often has high operating resistance, requiring the user to apply considerable force to complete the reversal, which is inconvenient and may lead to fatigue damage to structural components if operated frequently.

[0006] Friction and sealing issues: Regardless of the mechanical adjustment method, sliding friction between moving parts is ubiquitous. This not only increases operational difficulty, but long-term friction also accelerates component wear, compromises sealing, and ultimately affects the reliability and airtightness of directional steam discharge. Simultaneously, the high-temperature steam environment places higher demands on the lubrication of moving parts and the weather resistance of materials.

[0007] Structural complexity and cost: To achieve reliable commutation and sealing, traditional structures often require more precision components (such as springs, complex seals, linkage mechanisms, etc.), which increases manufacturing complexity and cost.

[0008] Therefore, there is an urgent need for a steam reversing device that is simple in structure, easy to operate, reliably sealed, and durable, in order to improve the user experience and lifespan of humidifiers. Utility Model Content

[0009] Therefore, in order to solve the problem of uneven adjustment of the flipping component in traditional humidifiers, this utility model provides a flipping exhaust device, the specific technical solution of which is as follows:

[0010] A tilting exhaust device includes a base and a rotating assembly. The rotating assembly includes a rotating housing, a first ball bearing, and a second ball bearing. The rotating housing is rotatably connected to the base. The rotating housing has a first sealed space and an air inlet, a first through hole, and a second through hole, all communicating with the first sealed space. The air inlet is used to allow gas to enter. The housing also has a first track and a second track, both inclined. The first ball bearing is disposed on and slidably connected to the first track, and the second ball bearing is disposed on and slidably connected to the second track. When the rotating housing is placed horizontally, the first ball bearing slides along the first track and blocks the first through hole, while the second ball bearing slides along the second track and moves away from the second through hole. When the rotating housing rotates, the second ball bearing slides along the second track and blocks the second through hole, while the first ball bearing slides along the first track and moves away from the first through hole.

[0011] The aforementioned flip-out exhaust device allows for easy switching of the steam passage simply by gently rotating the nozzle (rotating housing). The movement of the balls (first and second balls) on the inclined tracks (first and second tracks) is primarily driven by gravity. The rolling friction between the balls and tracks is significantly less than the sliding friction between moving parts in traditional designs, making it smooth and effortless for users to adjust the steam direction, requiring almost no force. When the rotating housing is at a specific angle (e.g., horizontally), the first ball slides down the first track under gravity, automatically and precisely sealing the first through-hole to form a reliable seal. Simultaneously, the second ball moves along the second track under gravity to a position away from the second through-hole, clearing the second passage. When the user rotates the nozzle angle, the direction of gravity changes relative to the tracks. The first ball bearing, under the influence of gravity, moves upward along the first track, automatically moving away from the first through-hole and releasing the blockage of the first channel. Simultaneously, the second ball bearing, under the influence of gravity, slides down the second track, automatically sealing the second through-hole. The entire process requires no additional operating force for sealing / opening; it is entirely driven by gravity and guided by the track, resulting in rapid and accurate switching. The core moving parts of this tilting exhaust device require only two balls and two matching inclined tracks. Compared to complex valves or linkage mechanisms, it has fewer parts, no complex moving pairs, fewer potential failure points, and minimal ball rolling friction wear. The tracks are typically designed inside the rotating housing, making them less prone to contamination. In high-temperature and high-humidity environments, the purely mechanical gravity-driven structure exhibits extremely high reliability and durability. This tilting exhaust device solves the problem of uneven adjustment of the tilting components in traditional humidifiers.

[0012] Furthermore, the flip-out exhaust device also includes a bellows with a conical outer contour, which is disposed on the base. One end of the bellows is a small opening, and the other end is a large opening. The large opening is used to allow gas to enter, and the small opening is connected to the air inlet.

[0013] Furthermore, the rotating assembly is also provided with an air guide, and when the rotating housing is placed horizontally, the second through hole communicates with the air guide.

[0014] Furthermore, the rotating housing is provided with a first limiting groove and a second limiting groove, and the first ball and the first track are both disposed in the first limiting groove. The first limiting groove is used to prevent the first ball from derailing from the first track.

[0015] Furthermore, both the second ball and the second track are disposed within the second limiting groove, which is used to prevent the second ball from derailing from the second track. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0027] like Figure 1 As shown in Figure 4, a flip-type exhaust device according to one embodiment of the present invention includes a base 1 and a rotating assembly. The rotating assembly includes a rotating housing 2, a first ball bearing 3, and a second ball bearing 4. The rotating housing 2 is rotatably connected to the base 1. The rotating housing 2 has a first sealing space 5 and an air inlet 6, a first through hole 7, and a second through hole 8, all of which are connected to the first sealing space 5. The air inlet 6 is used to allow gas to enter. The housing 2 also has a first track 9 and a second track 10, both of which are inclined. The first ball bearing 3 is disposed on the first track 9 and slidably connected to the first track 9, and the second ball bearing 4 is disposed on the second track 10 and slidably connected to the second track 10. When the rotating housing 2 is placed horizontally, the first ball bearing 3 slides along the first track 9 and blocks the first through hole 7, and the second ball bearing 4 slides along the second track 10 and moves away from the second through hole 8. When the rotating housing 2 rotates, the second ball bearing 4 slides along the second track 10 and blocks the second through hole 8, and the first ball bearing 3 slides along the first track 9 and moves away from the first through hole 7.

[0028] The aforementioned flip-out exhaust device allows for easy switching of the steam passage simply by gently rotating the nozzle (rotating housing 2). The movement of the balls (first ball 3, second ball 4) on the inclined tracks (first track 9, second track 10) is primarily driven by gravity. The rolling friction between the balls and tracks is significantly less than the sliding friction between moving parts in traditional designs, making it smooth and effortless for users to adjust the steam direction, requiring almost no force. When the rotating housing 2 is at a specific angle (e.g., horizontally placed), the first ball 3 slides down the first track 9 under gravity, automatically and precisely sealing the first through hole 7, forming a reliable seal. Simultaneously, the second ball 4 moves along the second track 10 under gravity to a position away from the second through hole 8, ensuring the second passage remains unobstructed. When the user rotates the nozzle angle, the direction of gravity relative to the tracks changes. The first ball bearing 3 moves upward along the first track 9 under gravity, automatically moving away from the first through hole 7 and releasing the blockage of the first channel. Simultaneously, the second ball bearing 4 slides down along the second track 10 under gravity, automatically sealing the second through hole 8. The entire process requires no additional force for sealing / opening; it is entirely driven by gravity and guided by the tracks, resulting in rapid and accurate switching. The core moving parts of this tilting exhaust device require only two balls and two matching inclined tracks. Compared to complex valves or linkage mechanisms, it has fewer parts, no complex moving pairs, fewer potential failure points, and minimal ball rolling friction wear. The tracks are typically designed within the rotating housing 2, making them less prone to contamination. In high-temperature and high-humidity environments, the purely mechanical gravity-driven structure offers extremely high reliability and durability. This tilting exhaust device solves the problem of uneven adjustment of the tilting components in traditional humidifiers.

[0029] like Figure 2 As shown in Figure 4, in one embodiment, the tilting exhaust device further includes a bellows 11 with a conical outer contour. The bellows 11 is disposed on the base 1, with one end being a small-mouth end and the other end being a large-mouth end. The large-mouth end is used for gas entry, and the small-mouth end is connected to the air inlet 6. Thus, the bellows 11 connects the air inlet 6 (large-mouth end) of the base 1 to the air inlet 6 (small-mouth end) of the rotating housing 2, providing a flexible and reliable sealed connection. The expansion and bending characteristics of the bellows 11 allow the rotating housing 2 to maintain airflow continuity and prevent leakage when tilting at an angle on the base 1, without pulling or disconnecting the airflow due to rotation. The conical shape (large-mouth inlet, small-mouth outlet) helps to collect and guide gas from the base 1 into the first sealed space 5 of the rotating housing 2 stably.

[0030] like Figure 2As shown, in one embodiment, the rotating assembly is further provided with a gas guide 12. When the rotating housing 2 is placed horizontally, the second through hole 8 communicates with the gas guide 12. Thus, when the rotating housing 2 is in a horizontal position (when the second through hole 8 is unobstructed), the gas guide 12 communicates with the second through hole 8, which can guide the gas (such as steam) flowing out of the second through hole 8 to be discharged in a predetermined direction (such as upward or at a specific angle).

[0031] like Figure 4 As shown, in one embodiment, the rotating housing 2 is provided with a first limiting groove 13 and a second limiting groove 14. The first ball 3 and the first track 9 are both disposed in the first limiting groove 13, which is used to prevent the first ball 3 from derailing from the first track 9. The second ball 4 and the second track 10 are both disposed in the second limiting groove 14, which is used to prevent the second ball 4 from derailing from the second track 10. In this way, the first ball 3 / track and the second ball 4 / track are respectively constrained in the groove by the first limiting groove 13 and the second limiting groove 14, effectively preventing the balls from accidentally derailing from the track during movement. The limiting grooves ensure that the balls move strictly along the predetermined track (first track 9, second track 10) without deviation or jamming, which is a key guarantee for achieving automatic and precise sealing / opening of through holes.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
