Description
Technical Field
[0001] The present application relates to the technical field of humidifiers, and in particular to a water circulation system of a humidifier. Background Art
[0002] A humidifier is a household appliance used to increase the humidity in a room or specific space. It does this by adding moisture to the air, raising the humidity level and thus creating a more comfortable and healthier environment for the occupants.
[0003] The Chinese invention patent with application number CN202311498009.5 discloses a high-efficiency humidifier, which includes a water storage part and a humidifying part. The humidifying part is arranged in the water storage part and can rotate in the water storage part; the first air inlet is opened in the humidifying part, and the first air inlet is used to allow wind to enter from the middle of the humidifying part and diffuse toward the edge of the humidifying part.
[0004] In the above solution, a humidifying unit (i.e., a rotor) rotates within a water storage unit (i.e., a water tray). This rotation of the rotor draws water from the tray, which is then blown out of the humidifier by wind, achieving indoor humidification. However, as the water in the tray is constantly drawn out, the amount of water inside decreases. Users are unable to determine the amount of water in the tray and are unable to add water in a timely manner, resulting in insufficient water carried by the rotor and poor humidification. Furthermore, when the humidifier is idle, a certain amount of water remains in the tray. If this residual water is not used for an extended period, it can become moldy, bacterial, and odorous. This can affect environmental hygiene while the humidifier is still operating, significantly reducing the user's experience with the humidifier. Utility Model Content
[0005] In order to solve the problems raised in the above background technology that the water receiving tray of the existing humidifier cannot be replenished with water in time, and the residual water when idle is prone to mold, bacterial growth and odor, the present application provides a water circulation system for a humidifier.
[0006] The water circulation system of a humidifier provided in this application adopts the following technical solution:
[0007] A water circulation system for a humidifier includes a water receiving tray and:
[0008] water tank;
[0009] A water outlet pipe is connected to the water tank and the water receiving tray, and is configured to guide the liquid in the water tank into the water receiving tray;
[0010] A water return pipe is connected to the water tank and the water receiving tray, and is configured to guide the liquid in the water receiving tray into the water tank;
[0011] When the amount of liquid in the water receiving tray is lower than a threshold value, the liquid in the water tank can enter the water receiving tray through the water outlet pipe to replenish the amount of liquid in the water receiving tray.
[0012] By adopting the above technical solution, a water tank is added on the basis of the water receiving tray set inside the original humidifier, so that water can be replenished in time when the water level inside the water receiving tray is reduced, so as to avoid the problem of low water carrying capacity and poor humidification effect of the internal wheel of the humidifier during rotation; in addition, when the humidifier is idle, the water in the water receiving tray can be reintroduced into the water tank through the return pipe, so as to avoid the problem of residual water in the water receiving tray becoming moldy, bacterial growth and odor due to the humidifier not being used for a long time, which is beneficial to improving the hygiene inside the humidifier.
[0013] Optionally, a frame is further included, the water receiving tray is located inside the frame, and the water tank is fixed on the frame.
[0014] By adopting the above technical solution, the humidifier is assembled using the support members of the frame water receiving tray and the water tank.
[0015] Optionally, a concave water receiving trough is provided inside the frame, and one end of the root of the water receiving trough extends toward the water tank, so that the liquid is introduced into the water tank from the water receiving trough.
[0016] By adopting the above technical solution, during the process of returning or adding water, the water can be placed in the water receiving trough first, and then flow from the water receiving trough to the water tank, so as to avoid the problem of poor water addition or return caused by the water inlet of the water tank being too small.
[0017] Optionally, the top of the frame has a concave water inlet, which is connected to the water receiving trough.
[0018] By adopting the above technical solution, when adding water to the water tank, the user can directly pour water at the water inlet, so that the water can enter the water receiving trough and then flow into the water tank, thereby improving the convenience of adding water.
[0019] Optionally, a pumping member is provided at one end of the return water pipe close to the water receiving tray, and the pumping member is rotatably installed above the water receiving tray; the other end of the return water pipe is connected to the inner cavity of the water tank.
[0020] By adopting the above technical solution, during the water return process, water can first enter the pumping element and then enter the water return pipeline.
[0021] Optionally, the water pumping member includes a rotating shaft, which is rotatably mounted on a mounting bracket fixed inside the humidifier. A torsion spring is sleeved on the rotating shaft so that the water pumping member always flips in a specified direction when not affected by external force.
[0022] By adopting the above technical solution, the torsion spring can be used to drive the pumping part to always rotate to the specified position. When external force acts on the pumping part, the elastic force of the torsion spring can be overcome to cause the pumping part to rotate, thereby meeting the change of working state when pumping or not pumping water.
[0023] Optionally, the pumping member also includes a suction pipe fixed at one end of the rotating shaft and perpendicular to the rotating shaft, the end of the rotating shaft has a joint connected to the suction pipe, the joint is connected to the end of the return pipe, and a first limit rod and a second limit rod extending along its radial direction are provided on the outside of the rotating shaft.
[0024] By adopting the above technical solution, the water suction pipe is immersed in the water in the water receiving tray, so that water can enter the water suction pipe when pumping water, and then enter the return pipe through the structure; the first limit rod and the second limit rod mainly play the role of limiting the rotation of the rotating shaft, and the first limit rod and the second limit rod form a V-shaped structure. When the humidifier wheel is placed in the water receiving tray, the wheel can drive the pumping part to rotate so that the water suction pipe is immersed in water. When the humidifier wheel is taken out of the water receiving tray, since the pumping part is not subjected to external force, the torsion spring can drive the pumping part to rotate to the specified position. The specified position is the state where the water suction pipe port is above the outside of the water receiving tray, which can facilitate the removal of the water receiving tray from the inside of the humidifier to prevent interference.
[0025] Optionally, water pumps are installed on both the return pipe and the outlet pipe.
[0026] By adopting the above technical solution, the water pump is used as the power source for water outflow and water inflow, which can meet the needs of different working conditions.
[0027] Optionally, a visual window is provided on the outer surface of the water tank.
[0028] By adopting the above technical solution, the user can conveniently observe the water level in the water tank and replenish the water tank in time.
[0029] Optionally, a liquid level sensor is installed inside the water receiving tray.
[0030] By adopting the above technical solution, the water level inside the water receiving tray can be monitored in real time. When the liquid level drops, a signal can be transmitted to the control system of the humidifier, thereby achieving the effect of water replenishment in time.
[0031] In summary, this application includes at least one of the following beneficial technical effects:
[0032] 1. The utility model has a reasonable design structure. On the basis of the traditional humidifier having a water receiving tray, a water tank is added to effectively control the water level in the water receiving tray, so that when the humidifier is working, there is always enough water in the water receiving tray, ensuring that the water carrying capacity of the humidifier's rotor is always in a sufficient state, thereby improving the humidification efficiency.
[0033] 2. The utility model can redirect the residual water in the water receiving tray into the water tank when the humidifier is in an idle state, thereby avoiding the problem of mold and odor inside the humidifier due to the presence of residual water and improving sanitary conditions.

DETAILED DESCRIPTION
[0045] The present application is further described in detail below with reference to the accompanying drawings.
[0046] like Figure 1-8As shown, an embodiment of the present application discloses a water circulation system of a humidifier, including a water receiving tray 3. In this example, the water receiving tray 3 is a box-shaped structure with an upper opening, and a certain amount of water can be stored inside it. The lower part of the humidifier's rotor can be immersed in water. In this way, when the rotor rotates, the water can be brought up, and the humid air is blown into the outside of the humidifier (indoors) under the action of wind, thereby achieving a humidification effect. This humidification principle, the installation structure and principle of the rotor are all conventional means in the prior art, and will not be elaborated here.
[0047] In addition, the water circulation system of this humidifier also includes a water tank 2, a water outlet pipe 5 and a water return pipe 7, wherein:
[0048] The water outlet pipe 5 is connected to the water tank 2 and the water receiving tray 3 and is configured to guide the liquid in the water tank 2 into the water receiving tray 3;
[0049] The return water pipe 7 is connected to the water tank 2 and the water receiving tray 3 and is configured to guide the liquid in the water receiving tray 3 into the water tank 2;
[0050] Specifically, water pumps are installed on both the return pipe 7 and the outlet pipe 5. Figure 5 As shown, the water pump in the middle of the outlet pipe 5 is the outlet pump 4, and the water pump in the middle of the return pipe 7 is the return pump 6. The two water pumps can work independently under the control of the humidifier control system, thereby achieving different effects of the water in the water tank 2 flowing to the water receiving tray 3, and the water in the water receiving tray 3 flowing into the water tank 2. More specifically, one end of the water outlet pipe 5 close to the water tank 2 is connected to the water outlet 201 below the water tank 2, and after passing through the water outlet pump 4, the other end is placed above the water receiving pan 3; the return water pipe 7 also connects the internal cavity of the water tank 2 and the internal cavity of the water receiving pan 3. Specifically, a pumping component 8 is installed at one end of the return water pipe 7, and the water suction pipe 801 of the pumping component 8 can be immersed in the water in the water receiving pan 3. The other end of the return water pipe 7 is connected to the frame 1, and its internal cavity is connected to the internal cavity of the water receiving trough 101 on the frame 1. Since the water receiving trough 101 is connected to the internal cavity of the water tank 2, the effect of being connected to the internal cavity of the water tank 2 is achieved.
[0051] When the amount of liquid in the water receiving tray 3 is lower than a threshold value, the liquid in the water tank 2 can enter the water receiving tray 3 through the water outlet pipe 5 to replenish the amount of liquid in the water receiving tray 3 .
[0052] Specifically, it also includes a frame 1, the water receiving tray 3 is located inside the frame 1, and the water tank 2 is fixed on the frame 1. In this example, the water receiving tray 3 is installed near the bottom of the frame 1, and the water tank 2 is arranged outside the frame 1, and a visual window is provided on the outer surface of the water tank 2. In this example, the casing near the outside of the water tank 2 is set to a transparent structure, or the entire water tank 2 is made of transparent material, so that the user can observe the changes in the water level in the water tank 2 and replenish the water in time.
[0053] Specifically, a concave water receiving groove 101 is provided inside the frame 1, and one end of the root of the water receiving groove 101 extends toward the water tank 2. The liquid is introduced into the water tank 2 from the water receiving groove 101. In this example, since the overall width of the water tank 2 is small, the opening of the water tank 2 is small (this is to save space and make the humidifier structure more compact). Therefore, a water receiving groove 101 with a width greater than the width of the water tank 2 is designed on the frame 1 above the opening of the water tank 2, so that the water in the water adding and returning process can first enter the water receiving groove 101 and then flow into the water tank 2.
[0054] Specifically, the top of the frame 1 has a concave water inlet 102, which is connected to the water receiving tank 101, so that the user can add water easily.
[0055] The return water pipe 7 is provided with a pumping member 8 at one end close to the water receiving tray 3 , and the pumping member 8 is rotatably installed above the water receiving tray 3 ; the other end of the return water pipe 7 is connected to the inner cavity of the water tank 2 .
[0056] Specifically, the pumping member 8 includes a rotating shaft 802, which is rotatably mounted on a mounting bracket 9 fixed inside the humidifier. A torsion spring 10 is sleeved on the rotating shaft 802, so that the pumping member 8 always flips in a specified direction when not affected by external force.
[0057] More specifically, the water-pumping member 8 further includes a water suction pipe 801 fixed at one end of the rotating shaft 802 and perpendicular to the rotating shaft 802. The end of the rotating shaft 802 has a joint 804 connected to the water suction pipe 801. The joint 804 is connected to the end of the return pipe 7. A first limiting rod 803 and a second limiting rod 805 extending in the radial direction are provided on the outside of the rotating shaft 802. The first limiting rod 803 and the second limiting rod 805 are mainly used to limit the rotation stroke of the rotating shaft 802. In this state, the water suction pipe 801 can be placed in the water receiving tray 3. The upper portion is in a certain tilted state, so even if the water suction pipe 801 is a hose, it can prevent it from bending or folding, and will not affect the water absorption effect. Moreover, in this state, the water suction pipe 801 can touch the lowest point inside the water receiving tray 3, thereby draining the water in the water receiving tray 3 without any residual water. When the rotating shaft 802 rotates forward to the limit state, the first limiting rod 803 can contact the inner wall of the frame 1 to achieve limiting. When the rotating shaft 802 rotates reversely to the limit state, the second limiting rod 805 can contact the inner wall of the water receiving tray 3, and can also achieve a limiting effect.
[0058] In this example, the mounting bracket 9 is fixed to the frame 1 and is located above the water receiving tray 3. In a natural state, that is, when the pumping member 8 is only subjected to the force of the torsion spring 10, the suction pipe 801 of the pumping member 8 can be flipped to a position above the water receiving tray 3, that is, the suction pipe 801 is approximately parallel to the horizontal plane. In this state, there are no other parts around the water receiving tray 3 to interfere, which makes it convenient for users to disassemble or install the water receiving tray 3. When the pumping member 8 is flipped by an external force, that is, after the runner is installed inside the water receiving tray 3, the runner can apply force to the pumping member 8, causing the suction pipe 801 of the pumping member 8 to be tilted, and the end of the suction pipe 801 is submerged in water. In this way, after the return water pump 6 is started, the water in the water receiving tray 3 can be introduced into the water tank 2 through the suction pipe 801 and the return water pipeline 7.
[0059] Specifically, a liquid level sensor (not shown) is installed within the water receiving pan 3 to monitor the water level within the water receiving pan 3 in real time. This liquid level sensor is electrically connected to the humidifier's control system and generates a signal when the water level falls below a certain threshold. The control system then controls the water outlet pump 4 to promptly direct water from the water tank 2 into the water receiving pan 3 via the water outlet pipe 5, thereby replenishing the water. The structure and principle of the electrical connection between the liquid level sensor, the humidifier control system, and the water outlet pump 4 are conventional means for achieving electrical control in the prior art and will not be elaborated upon here.
[0060] This humidifier's water circulation system incorporates a water tank 2. When the water level in the water tray 3 is insufficient, water from the water tank 2 is promptly added to the water tray 3. This ensures that the water tray 3 always has a sufficient amount of water, allowing the rotor to carry sufficient water when rotating, thereby improving the humidification effect. Furthermore, when the humidifier is not in use for an extended period of time, the water in the water tray 3 can be directed into the water tank 2, eliminating any residual water in the water tray 3 and preventing mold and odor from forming inside the humidifier due to residual water.
[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
