Description

Technical Field

[0001] The present invention relates to the technical field related to household appliances, and particularly relates to a water stop cover assembly and an atomizer to which the water stop cover assembly is applied. Background Art

[0002] An atomizer (or a humidifier) is a household appliance product that can improve the humidity and temperature of a local environment. A common atomizer product, such as the Chinese invention patent with the publication number CN103644618A, discloses a humidifier, which includes a base and a water tank. A control circuit board and a fan are provided inside the base. A water tank is provided on the base. An ultrasonic atomizer and a air supply duct communicating with the fan are installed at the bottom of the water tank. The upper end of the air supply duct has an air outlet; a water valve is provided at the bottom of the water tank. A float switch is provided below the water valve at the bottom of the water tank. The water valve can be opened or closed through the float switch, so as to fill water into the water tank or close it. The air supply duct of this humidifier structure communicates the inside of the base with the water tank. If the float switch fails or the humidifier tilts, the water in the water tank may enter the inside of the base through the air supply duct, and electrical components such as the control circuit board and the fan are likely to short-circuit, resulting in product failure or scrapping. Summary of the Invention

[0003] In order to overcome at least one of the above problems existing in the atomizer in the prior art, the present invention provides a water stop cover assembly, which includes a cap-shaped cap. The cap includes a top wall and a side wall surrounding the top wall. A side door opening is provided on the side wall at the front side of the cap; a movable member is further included. The movable member includes a plate-shaped upper baffle and a lower counterweight. The upper baffle and the lower counterweight are integrally formed. A rotating shaft portion is provided between the upper baffle and the lower counterweight. The movable member is arranged at the side door opening of the cap and is rotatably connected to the side walls on both sides of the side door opening through the rotating shaft portion. The upper baffle of the movable member extends into the inner space of the cap; when the cap is arranged upright up and down, the movable member can be turned forward, the top end of the upper baffle abuts against the inner side of the upper frame edge of the side door opening, and the lower counterweight hangs down in a counterweight manner outside the cap, so that the top end of the upper baffle stably abuts against the upper frame edge of the side door opening; when the cap tilts backward, the upper baffle turns backward, and the top end of the upper baffle leaves the inner side of the upper frame edge of the side door opening.

[0004] Among them, the cap is a cap-shaped member including a side wall and a top wall. The upper end of the side wall is connected to the top wall to achieve top covering, and the lower edge of the side wall forms an opening for sleeving on the air duct of the atomizer mentioned below. The shape of the side wall of the cap is adapted to the sleeved member. In a common implementation, the side wall includes four wall bodies, namely, a front wall, a rear wall, a left wall, and a right wall, and the four wall bodies are connected to form a square column shape to adapt to the column-shaped air duct; or the side wall is cylindrical to adapt to the cylindrical air duct, etc. However, the front side wall in the present invention does not limit that the side wall must be a four-sided square column shape. The front and rear directions here are only defined for the convenience of description. The front side refers to one side of the product in a certain specified direction, and the rear side is behind the front side. The "rear" in the "tilting backward" mentioned later refers to the rear side. As long as the connection with other components is not affected, the front side wall can be flat or arc-shaped.

[0005] Among them, the side door opening refers to an opening structure provided on the front side wall, and this opening is the position where the movable member is arranged. The specific structure of the side door opening at least includes the following two types. The first type is a through-hole structure formed on the wall body, and an annular side wall body is arranged around the side door opening; the second type is that the side door opening is in the shape of a door frame, and its lower part is communicated with the lower opening of the cap. However, regardless of the shape, left and right side wall bodies are respectively provided on the left and right sides of the side door opening, and an upper frame edge is provided on the upper side.

[0006] Among them, the movable member is a movable component movably arranged in the side door opening, and it rotates around the central axis of the rotating shaft part. Its rotation principle is that the movable member rotates around the central axis due to the offset of the center of gravity when in different arrangement postures. In order to enable the movable member to rotate better as required, the movable member includes an upper baffle and a lower counterweight arranged up and down. Among them, the upper baffle is arranged upright in the generally up and down direction, and the lower counterweight is connected to the lower end of the upper baffle and extends forward in a direction substantially perpendicular to the upper baffle. The rotating shaft part is arranged at the intersection of the upper baffle and the lower counterweight or on the upper baffle and the lower counterweight near the intersection. When the movable member is arranged upright up and down, the center of gravity of the movable member is located on one side of the lower counterweight, so that the movable member flips forward; when the movable member lies flat backward, the center of gravity of the movable member is located on one side of the upper baffle, so that the movable member flips forward.

[0007] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: First, by providing the movable member on the cap, not only can the water-stop cap assembly be stably connected to the air duct through the cap, but also the upper baffle on the movable member can be used to control the opening or closing of the air outlet on the air duct. This can not only ensure normal exhaust from the air outlet in the normal working state with the product upright, but also close the air outlet in the abnormal working state when the product is tilted backward to reduce the accidental entry of water into the product interior from the air outlet, greatly improving the service life and safety of the product. Second, the movable member is rotatably connected to one side wall of the cap. By providing the upper baffle and the lower counterweight, the movable member can perform forward or backward flipping actions due to the center-of-gravity offset in different placement states. These two actions also well adapt to the normal working state and the backward-tilted state of the product, realizing automatic adaptation control of the product through a simple structure without the need for manual or electronic control, which is very convenient.

[0008] An atomizer specifically applying the water-stop cap assembly includes a main body. A water storage tank is provided on the upper wall of the main body. An atomization device is provided at the bottom of the water storage tank for atomizing the water in the water storage tank. An upward-extending air duct is also provided in the water storage tank. An air outlet is provided at the upper end of the front side wall of the air duct. A blower and a controller are also provided in the main body. The controller is connected to and controls the blower and the atomization device. The air generated by the blower flows upward under the guidance of the air duct and is discharged from the air outlet. It also includes the above-mentioned water-stop cap assembly. The cap is sleeved on the upper end of the air duct. The upper baffle is provided outside the air outlet. When the main body is arranged upright, the upper baffle flips forward to open the air outlet. When the main body is tilted backward, the upper baffle flips backward to press and seal the air outlet.

[0009] Due to the above characteristics and advantages of the present invention, it can be applied to the water-stop cap assembly and the atomizer to which it is applied. Description of the Drawings

[0019] The following further describes the structure of the water stop cover assembly applying the technical solution of the present invention and the atomizer to which it is applied with reference to the accompanying drawings.

[0020] Except for the embodiments that are clearly stated as equivalent or alternative, the various implementation details disclosed below can be selectively applied or combined and applied in one embodiment even if there is no direct association or synergy in terms of function.

[0021] As Figures 1 to 3 shown in the figure is an atomizer. The atomizer includes a main body 1. A water storage tank 10 is provided on the upper wall of the main body 1. An atomizing device 2 is provided at the bottom of the water storage tank 10. The atomizing device 2 is used to atomize the water in the water storage tank 10. A gas guide pipe 11 extending upward is further provided in the water storage tank 10. An air outlet 12 is provided at the upper end of the wall on the front side of the gas guide pipe 11. A fan 3 and a controller 4 are further provided in the main body 1. The controller 4 is connected to the fan 3 and the atomizing device 2 and can control the operation and stop of the fan 3 and the atomizing device 2. The air generated by the fan 3 flows upward under the guidance of the gas guide pipe 11 and is discharged from the air outlet 12. The lowest point of the air outlet 12 is higher than the maximum water level height of the water storage tank 10. It further includes a water tank 5. The water tank 5 is detachably connected to the main body 1. A mist discharge pipe 51 is further provided on the water tank 5. The mist discharge pipe 51 is arranged above the water storage tank 10. In this way, the air discharged from the air outlet 12 can carry the water mist and be discharged outward through the mist discharge pipe 51.

[0022] In this embodiment, the air duct 11 is arranged on the rear side of the water storage tank 10. When the atomizer is tilted backward, the water in the water storage tank 10 will flow along the extension direction of the air duct 11. In this way, the water may flow into the interior of the main body 1 from the air outlet 12, causing electrical components such as the controller 4 and the fan 3 to short-circuit and malfunction. Therefore, in the present invention, a water stop cover assembly is further provided on the air duct 11. As Figures 4 to 9 shown, the water stop cover assembly includes a cap-shaped cap 6. The cap 6 includes a top wall 63 and a side wall 61 surrounding the top wall 63. A side door opening 62 is provided on the side wall 61 at the front side of the cap 6; it further includes a movable member 7. The movable member 7 includes a plate-shaped upper baffle 71 and a lower counterweight 72. The upper baffle 71 and the lower counterweight 72 are integrally formed. A rotating shaft portion 73 is provided between the upper baffle 71 and the lower counterweight 72. The movable member 7 is arranged at the side door opening 62 of the cap 6 and the movable member 7 is rotatably connected to the side walls 61 on both sides of the side door opening 62 through the rotating shaft portion 73, and the upper baffle 71 of the movable member 7 extends into the inner space of the cap 6; when the cap 6 is arranged upright up and down, the movable member 7 can be flipped forward, the top end of the upper baffle 71 abuts against the inner side of the upper frame edge of the side door opening 62, and the lower counterweight 72 hangs down in a counterweight manner outside the cap 6, so that the top end of the upper baffle 71 stably abuts against the upper frame edge of the side door opening 62; when the cap 6 is tilted backward, the upper baffle 71 is flipped backward, and the top end of the upper baffle 71 leaves the inner side of the upper frame edge of the side door opening 62.

[0023] Among them, the cap 6 includes a top wall 63 and a side wall 61 surrounding the top wall 63. The lower part has an opening so that it can be sleeved on the upper end of the air duct 11. The shape of the side wall 61 of the cap 6 is adapted to the sleeved air duct 11. In this embodiment, both the air duct 11 and the side wall 61 of the cap 6 are in the shape of a quadrilateral tube, that is, the side wall 61 includes a front side wall 611, a rear side wall 612, a left side wall 613 and a right side wall 614. The side door opening 62 is arranged on the front side wall 611, and the movable member 7 is arranged at the side door opening 62 of the cap 6. When the cap 6 is sleeved on the air duct 11, the side door opening 62 faces the air outlet 12. The upper baffle 71 is arranged outside the air outlet 12. When the main body 1 is placed upright, the upper baffle 71 flips forward to open the air outlet 12; when the main body 1 tilts backward, the upper baffle 71 flips backward to press against and block the air outlet 12. The beneficial technical effects of the present invention are as follows: First, by arranging the movable member 7 that can move on the cap 6, not only can the water stop cap assembly be stably connected to the air duct 11 through the cap 6, but also the upper baffle 71 on the movable member 7 can be used to control the opening or closing of the air outlet 12 on the air duct 11, reducing the probability of water entering the product interior from the air outlet 12 and greatly improving the service life and safety of the product; Second, the movable member 7 is rotatably connected to one side wall of the cap 6. By arranging the upper baffle 71 and the lower counterweight 72, the movable member 7 can perform forward or backward flipping actions due to the center of gravity offset in different placement states. These two actions also well adapt to the normal working state and the backward tilting state of the product, realizing automatic adaptation control of the product through a simple structure without the need for manual operation or electronic control, which is very convenient.

[0024] Further, the lower counterweight 72 includes a horizontal baffle 721 and a surrounding baffle 722 connected to the bottom of the horizontal baffle 721. The rear edge of the horizontal baffle 721 is connected to the lower end of the upper baffle 71 and extends forward. The surrounding baffle 722 is in the shape of a "∏" and extends downward along the left, right and front edges of the horizontal baffle 721. The surrounding baffle and the lower counterweight 72 are combined to define a baffle cavity. The advantage of such a setting is that when water rushes towards the movable member 7 along the air duct 11, the water will first rush into the baffle cavity. When the horizontal baffle 721 and the surrounding baffle 722 are subjected to the impact force, the movable member 7 flips backward, and the upper baffle 71 of the movable member 7 presses backward against the wall body around the air outlet 12, which is beneficial to improving the water blocking effect.

[0025] In order to reduce the influence of the water stop cover assembly on the air flow from the air outlet 12, the width of the upper baffle 71 is smaller than the width of the side door opening 62, and an air passing gap is formed between the upper baffle 71 and the side wall 61 on both sides of the side door opening 62. A skylight opening 64 is further provided on the top wall 63 of the cap 6, and the air output from the air outlet 12 can also be blown outwards from the skylight opening.

[0026] In order to better guide the air flow and reduce the problem that the skylight opening 64 is blocked, upper sealing ribs 65 arranged at intervals in the front and rear are further provided on the upper wall surface of the top wall 63 of the cap 6. The upper sealing ribs 65 and the top wall 63 of the cap 6 form an upper exhaust groove, and the skylight opening 64 is arranged between the two upper sealing ribs 65 and communicates with the upper exhaust groove. Further, side sealing ribs 66 arranged at intervals in the front and rear are also provided on the left side wall 61 and / or the right side wall 61. The side sealing ribs 66 and the side wall 61 form a side exhaust groove, and the side exhaust groove communicates with the upper exhaust groove.

[0027] As Figure 3 、 Figure 5 shown in Figure 9 the water stop cover assembly further includes a seal 8. The seal 8 is made of soft rubber (such as silica gel or rubber). The seal 8 is connected to the upper baffle 71, and the seal 8 at least covers the wall surface on the inner space side of the upper baffle 71 facing the cap 6. Further, a sealing rib 81 is provided on the outer surface of the seal 8 on the side facing the inner space, and the sealing rib 81 is arranged along the edge of the seal 8. The advantage of this is that when the movable member 7 is turned backwards, the upper baffle 71 can press the seal 8 backwards against the wall body around the air outlet 12, and the sealing rib 81 of the seal 8 and the wall body form a line seal, which is beneficial to further improving the sealing effect. In another equivalent embodiment, the surface of the seal 8 is a flat surface, and a rib (not shown in the figure) is further provided at the upper end of the front side wall of the air guide pipe 11. The rib is arranged along the edge of the air outlet 12. In this way, the seal 8 pressing on the rib can also form a line seal.
