Description

Technical Field

[0001] The present invention relates to the technical field of humidifiers, and particularly to a water tank structure and a humidifier. Background Art

[0002] When the air conditioner is turned on in winter or summer, the indoor air is very dry, which makes people's skin prone to chapping due to the dry air, affecting the user experience. To improve people's comfort, a humidifier is generally configured in the room to increase the room humidity.

[0003] A humidifier generally includes a water tank. An air outlet duct is generally formed inside the water tank. The air outlet end of the fan is communicated with the air inlet end of the air outlet duct to discharge the generated air flow along the air outlet duct. However, in the traditional humidifier, water easily enters the air outlet duct during the cleaning process, wetting the fan and affecting the operation of the fan. Summary of the Invention

[0004] Based on this, in view of the problem that water easily enters the air outlet duct during the cleaning process of the water tank in the traditional humidifier, wetting the fan and affecting the operation of the fan, a water tank structure and a humidifier are provided. When in use, the water tank structure and the humidifier can prevent water from entering the air outlet duct and thus damaging the fan.

[0005] The specific technical solutions are as follows:

[0006] On the one hand, the present application relates to a water tank structure, including a water tank and a switch assembly. An air outlet duct is formed on the side wall of the water tank. The air outlet duct is provided with an air outlet end, and the air outlet end is provided with an air outlet. The switch assembly includes a limiting member and a switch member. The limiting member is provided with a moving channel and an air discharge port communicated with the moving channel. The side wall of the limiting member is in a hollow shape, and a plurality of the air discharge ports are formed on the side wall. The limiting member is connected to the air outlet end, and the moving channel is communicated with the air outlet. The switch member is limit-mounted in the moving channel. Wherein, the switch member includes a first state and a second state. When the switch member is in the first state, the switch member moves relative to the moving channel under the push of the gas discharged along the air outlet duct to open the air outlet so that the gas can be discharged along the air discharge port. When the switch member is in the second state, the switch member moves along the direction close to the air outlet under the action of its own gravity to block the air outlet.

[0007] When the above-mentioned water tank structure is in use, the blower operates, and the switch member is in the first state. At this time, the switch member moves relative to the moving channel under the push of the gas discharged along the air outlet pipe, so as to open the air outlet so that the gas can be discharged along the air discharge port; when the water tank needs to be cleaned, the blower stops operating, and the switch member is in the second state. At this time, the switch member moves along the direction close to the air outlet to block the air outlet, so as to avoid water entering the air outlet pipe from the air outlet when cleaning the water tank and damaging the blower. Further, through the limiting effect of the moving channel, it is ensured that when switching between the first state and the second state, the switch member can leave the air outlet or fall to block the air outlet according to a preset path.

[0008] The technical solution will be further described below:

[0009] In one embodiment, when the switch member is in the first state, the switch member moves relative to the air outlet pipe under the push of the gas in the air outlet pipe until it abuts against the top wall of the moving channel. In this way, the moving height of the switch member is restricted.

[0010] In one embodiment, the air outlet pipe is an electromagnetic member, and the switch member is a magnetic member; when the switch member is in the first state, the air outlet pipe is powered off, and the switch member moves relative to the moving channel under the push of the gas discharged along the air outlet pipe, so as to open the air outlet so that the gas can be discharged along the air discharge port; when the switch member is in the second state, the air outlet pipe is powered on, and the switch member is magnetically coupled with the air outlet pipe, and the switch member moves along the direction close to the air outlet to block the air outlet.

[0011] In this way, the energized air outlet pipe will generate magnetism, and the switch member can be made of a magnetic material. When the energized air outlet pipe generates magnetism, it can be magnetically coupled with the switch member. When the switch member is in the first state, the air outlet pipe is powered off. At this time, there is no magnetic coupling between the air outlet pipe and the switch member, and the switch member moves relative to the moving channel under the push of the gas discharged along the air outlet pipe to open the air outlet so that the gas can be discharged along the air discharge port.

[0012] In one embodiment, the switch member is spherical, and the diameter of the switch member is larger than the diameter of the air outlet. In this way, when the switch member is in the second state, the switch member can block the air outlet when falling.

[0013] In one embodiment, the mass of the switch member is m, the gas flow velocity blown out along the air outlet pipe is V, and the diameter of the air outlet is R, where m < 1.176R 2The unit of V is m³, the unit of m is Kg, the unit of R is m, and the unit of V is m / s. Ensure that when the switch is in the first state, the switch can be pushed by the gas to leave the air outlet to open the air outlet.

[0014] In one embodiment, a limiting groove is provided at the air outlet end, and the limiting member is connected to the air outlet end by being inserted into the limiting groove.

[0015] In one embodiment, a first water outlet is further provided at the air outlet end, which penetrates through the side wall of the limiting groove. In this way, when the water in the water tank splashes onto the outer wall of the limiting member, the water will gather in the limiting groove and be discharged through the first water outlet.

[0016] In one embodiment, a storage groove is further provided at the air outlet end. The limiting groove is arranged within the area surrounded by the storage groove. The limiting groove communicates with the storage groove through the first water outlet. A second water outlet is further provided at the air outlet end, which penetrates through the side wall of the storage groove. In this way, the water splashed inside the water tank can be collected through the storage groove. In addition, the water discharged through the first water outlet can also be stored in the storage groove, and all this water can be discharged along the second water outlet.

[0017] In one embodiment, the limiting groove is a first annular groove, and the air outlet is arranged within the area surrounded by the limiting groove; the storage groove is a second annular groove, and the limiting groove is arranged within the area surrounded by the storage groove.

[0018] In one embodiment, the side wall of the limiting member is in a hollow shape.

[0019] On the other hand, the present application also relates to a humidifier, including the water tank structure in any of the above embodiments.

[0020] The humidifier includes the water tank structure in any of the above embodiments. Therefore, when the humidifier is in use, the fan operates, and the switch is in the first state. At this time, the switch moves relative to the moving channel under the push of the gas discharged along the air outlet pipe to open the air outlet so that the gas can be discharged along the air outlet; when the water tank needs to be cleaned, the fan stops operating, and the switch is in the second state. At this time, the switch moves along the direction close to the air outlet to block the air outlet, avoiding water entering the air outlet pipe from the air outlet during the cleaning of the water tank and damaging the fan. Further, through the limiting effect of the moving channel, it is ensured that when switching between the first state and the second state, the switch can leave the air outlet or fall to block the air outlet according to a preset path.

[0021] The technical solution will be further described below:

[0022] In one embodiment, the humidifier further includes a blower, the blower includes a second air outlet end, and the second air outlet end is communicated with the air inlet end of the air outlet duct. In this way, the airflow generated by the blower pushes the switch member to move relative to the moving channel, so that the switch member opens the air outlet. Description of the Drawings

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0036] This application proposes a humidifier 10, which can avoid water entering the air outlet duct 110 during use and damaging the blower 30.

[0037] Please refer to Figure 1 and Figure 2 , in one embodiment, the humidifier 10 includes a water tank structure 20, a water tank 40, and a blower 30. The water tank structure 20 includes a water tank 100. The water tank 40 is connected to the water tank 100, and the water tank 40 supplies water to the water tank 100 to ensure a constant water level in the water tank 100. During use, the user only needs to add water to the water tank 40. An air outlet duct 110 is formed on the side wall of the water tank 100. The air outlet duct 110 is provided with a first air outlet end 112. The blower 30 includes a second air outlet end, and the second air outlet end is communicated with the air inlet end of the air outlet duct 110. The first air outlet end 112 is provided with an air outlet 1122. The air flow generated by the blower 30 enters along the air inlet end of the air outlet duct 110 and is discharged along the air outlet 1122. Among them, the air outlet duct 110 can be integrally formed with the water tank 100. In other embodiments, the air outlet duct 110 and the water tank 100 can be monomeric structures and fixed by connection means such as welding.

[0038] When cleaning the water tank of a traditional humidifier, water easily enters the air outlet duct along the air outlet, thereby damaging the blower.

[0039] To solve the above problems, please refer to Figure 1 and Figure 2 In one embodiment, the water tank structure 20 further includes a switch assembly 200. The switch assembly 200 includes a limiting member 220 and a switch member 210. The limiting member 220 is provided with a moving channel 222 and an air outlet 224 communicating with the moving channel 222. The limiting member 220 is connected to the first air outlet end 112, and the moving channel 222 communicates with the air outlet 1122. The switch member 210 is limit-mounted in the moving channel 222. The switch member 210 includes a first state and a second state. The working principles of the switch member 210 in the first state and the second state are as follows:

[0040] Please refer to Figure 2 When the switch member 210 is in the first state, the switch member 210 moves relative to the moving channel 222 under the push of the gas discharged along the air outlet duct 110 to open the air outlet 1122. At this time, the gas can be discharged along the air outlet 224. Under the action of the blower 30, the gas needs to overcome the gravity of the switch member 210 itself to push the switch member 210 to move. Since the wind speed of the blower 30 is relatively low when the humidifier 10 is in use, the air resistance is relatively low and can be ignored.

[0041] Please refer to Figure 3 When the switch member 210 is in the second state, the switch member 210 moves along the direction close to the air outlet 1122 to block the air outlet 1122. At this time, the switch member 210 can rely on its own gravity to reset to block the air outlet 1122.

[0042] Further, please refer to Figure 2 In one embodiment, when the switch member 210 is in the first state, the switch member 210 moves relative to the air outlet duct 110 under the push of the gas in the air outlet duct 110 until it abuts and cooperates with the top wall of the moving channel 222. In this way, the moving height of the switch member 210 is restricted by the top wall of the moving channel 222.

[0043] Optionally, the limiting member 220 may be a cylindrical structure with one end open and the inside hollow, and the limiting member 220 is a long cylindrical shape; in order to improve the exhaust efficiency, the number of the air outlets 224 may be multiple; for example, please refer to Figure 4 In one embodiment, the side wall of the limiting member 220 is in a hollowed-out shape. At this time, a plurality of air outlets 224 are provided on the side wall of the limiting member 220 and are arranged at intervals along the circumferential direction of the limiting member 220. Please refer to Figure 4, in this embodiment, the air outlet 224 is a long strip hole, which is arranged along the depth direction of the moving channel 222.

[0044] When the above-mentioned water tank structure 20 and the humidifier 10 are in use, the fan 30 operates, and the switch 210 is in the first state. At this time, the switch 210 moves relative to the moving channel 222 under the push of the gas discharged along the air outlet pipe 110 to open the air outlet 1122, so that the gas can be discharged along the air outlet 224; when the water tank 100 needs to be cleaned, the fan 30 stops operating, and the switch 210 is in the second state. At this time, the switch 210 moves along the direction close to the air outlet 1122 to block the air outlet 1122, so as to prevent water from entering the air outlet pipe 110 through the air outlet 1122 and damaging the fan 30 when the water tank 100 is cleaned. In addition, through the limiting effect of the moving channel 222, it is ensured that when switching between the first state and the second state, the switch 210 can leave the air outlet 1122 or fall to block the air outlet 1122 according to a preset path. Further, by adopting the above method of opening or blocking the air outlet 1122, the structure is simple and the reliability is better.

[0045] Further, in order to ensure that when the switch 210 is in the first state, the switch 210 can leave the air outlet 1122 under the push of the gas to open the air outlet 1122. In one embodiment, the mass of the switch 210 is m, the gas flow velocity blown out along the air outlet pipe 110 is V, and the diameter of the air outlet 1122 is R. Among them, m < 1.176R 2 V, where the unit of m is Kg, the unit of R is m, and the unit of V is m / s.

[0046] Optionally, the switch 210 can be made of a light material, for example, rubber or plastic; the switch 210 can also be a hollow spherical structure.

[0047] In other embodiments, the air outlet pipe 110 is an electromagnetic part, the switch 210 is a magnetic attraction part, and the switch 210 can be made of a magnetic material. When the air outlet pipe 110 is electrified, it will generate magnetism, and when the air outlet pipe 110 is electrified to generate magnetism, it can cooperate magnetically with the switch 210.

[0048] When the switch 210 is in the first state, the air outlet pipe 110 is powered off. At this time, there is no magnetic attraction cooperation between the air outlet pipe 110 and the switch 210, and the switch 210 moves relative to the moving channel 222 under the push of the gas discharged along the air outlet pipe 110 to open the air outlet 1122, so that the gas can be discharged along the air outlet 224.

[0049] When the switch member 210 is in the second state, the air outlet duct 110 is electrified. At this time, the air outlet duct 110 generates magnetism when electrified, and the switch member 210 is magnetically attracted to the air outlet duct 110. The switch member 210 moves in the direction close to the air outlet 1122 to block the air outlet 1122. At this time, the switch member 210 can move and reset in the direction close to the air outlet 1122 under the combined action of its own gravity and the magnetic force generated by the air outlet duct 110 itself to block the air outlet 1122. At this time, the magnetic attraction between the switch member 210 and the air outlet duct 110 can also improve the reliability of blocking the air outlet 1122.

[0050] In another embodiment, the air outlet duct 110 is a magnetic member, and the switch member 210 is an electromagnetic member. The air outlet duct 110 is made of a magnetic material. When the switch member 210 is electrified, it generates magnetism, and when the switch member 210 generates magnetism when electrified, it can be magnetically coupled with the air outlet duct 110.

[0051] When the switch member 210 is in the first state, the switch member 210 is powered off. At this time, there is no magnetic attraction between the air outlet duct 110 and the switch member 210. The switch member 210 moves relative to the moving channel 222 under the push of the gas discharged from the air outlet duct 110 to open the air outlet 1122, so that the gas can be discharged along the air outlet 224.

[0052] When the switch member 210 is in the second state, the switch member 210 is electrified. At this time, the switch member 210 generates magnetism when electrified, and the switch member 210 is magnetically attracted to the air outlet duct 110. The switch member 210 moves in the direction close to the air outlet 1122 to block the air outlet 1122. At this time, the switch member 210 can move and reset in the direction close to the air outlet 1122 under the combined action of its own gravity and the attraction between it and the air outlet duct 110 to block the air outlet 1122. At this time, the magnetic attraction between the switch member 210 and the air outlet duct 110 can also improve the reliability of blocking the air outlet 1122.

[0053] Please refer to Figure 3 , in one specific embodiment, the switch member 210 is spherical, and the diameter of the switch member 210 is larger than the diameter of the air outlet 1122. In this way, when the switch member 210 is in the second state, the switch member 210 can block the air outlet 1122 when it falls.

[0054] To limit the moving path of the switch member 210 during rising and falling, the inner diameter of the moving channel 222 can be matched with the diameter of the switch member 210. In this way, when the gas pushes the switch member 210 to move, the switch member 210 will not float around, so that when the switch member 210 is in the second state, the switch member 210 can be reset smoothly to block the air outlet 1122.

[0055] In other embodiments, the switch member 210 may also be a square structure, or other irregular shapes, such as an ellipsoidal shape, etc. As long as it satisfies that when the switch member 210 is in the first state, the switch member 210 moves relative to the moving channel 222 under the push of the gas discharged along the air outlet duct 110 to open the air outlet 1122; and when the switch member 210 is in the second state, the switch member 210 moves in the direction close to the air outlet 1122 to block the air outlet 1122, which will not be elaborated one by one here.

[0056] Please refer to Figure 5 , in this embodiment, the first air outlet end 112 is provided with a limiting groove 1124, and the limiting member 220 is connected to the first air outlet end 112 by being inserted into the limiting groove 1124. During installation, one end of the limiting member 220 is inserted into the limiting groove 1124; the first air outlet end 112 is further provided with a first water outlet 11242 penetrating through the side wall of the limiting groove 1124. Thus, when the water in the water tank 100 splashes onto the outer wall of the limiting member 220, this water will flow down along the outer wall of the limiting member 220 and accumulate in the limiting groove 1124, and is discharged through the first water outlet 11242.

[0057] Please refer to Figure 5 , in one of the embodiments, the first air outlet end 112 is further provided with a receiving groove 1126, the limiting groove 1124 is arranged within the area surrounded by the receiving groove 1126, the limiting groove 1124 is communicated with the receiving groove 1126 through the first water outlet 11242, and the first air outlet end 112 is further provided with a second water outlet 11262 penetrating through the side wall of the receiving groove 1126. Thus, the water splashed inside the water tank 100 can be collected through the receiving groove 1126. In addition, the water discharged through the first water outlet 11242 can also be received in the receiving groove 1126, and all this water can be discharged along the second water outlet 11262.

[0058] Please refer to Figure 5 , the limiting groove 1124 is a first annular groove, and the air outlet 1122 is arranged within the area surrounded by the limiting groove 1124; the receiving groove 1126 is a second annular groove, and the limiting groove 1124 is arranged within the area surrounded by the receiving groove 1126; both the first water outlet 11242 and the second water outlet 11262 are four, and one first water outlet 11242 corresponds to one second water outlet 11262.
