Description

TECHNICAL FIELD

[0001] The utility model relates to humidifying fan field, concretely is a water tank connecting structure and humidifying fan. BACKGROUND

[0002] In the fan with humidifying function at present, usually including a water storage tank for storing water and a atomizing water tank for atomizing water, and the connecting structure of water storage tank and atomizing water tank is the key to realize the humidifying function. In the current structure, the inside of water storage tank is designed into a sealed cavity, when connecting with atomizing water tank, its water outlet will open to supply water to atomizing water tank, when the water level in atomizing water tank rises to the water outlet, the water outlet will be covered, preventing air from continuing to enter the water storage tank, because the inside of water storage tank is still in negative pressure state, preventing water flow from continuing to flow into atomizing water tank, so as to control the highest water level of atomizing water tank not to exceed the position of water outlet. When the water level of atomizing water tank drops, air will re-enter the water storage tank through the water outlet, so that the water in the water storage tank continues to flow into the atomizing water tank, realizing the automatic water supply process of circulation.

[0003] However, in the existing design, in order to ensure that there is enough space in the atomizing water tank for effective water atomization treatment, the water outlet structure of the water storage tank is usually designed to be long enough to penetrate into the atomizing water tank, so that the water outlet is closer to the bottom of the atomizing water tank to control the liquid level, but this will cause some problems, first, when the user needs to take out the water storage tank, the water storage tank needs to be lifted to the height where the water outlet structure completely separates from the atomizing water tank, which causes the user to lift the water storage tank to a very high position, increasing the operation difficulty and inconvenience. In addition, the too long water outlet structure not only increases the manufacturing cost, but also reduces the strength of the overall structure, when accidentally colliding with the water outlet structure, it is more likely to cause damage to the water outlet structure and thus damage the sealing problem.

[0004] Therefore, it is necessary to develop a water tank connecting structure and humidifying fan which can effectively reduce the length of the water outlet structure on the water storage tank. UTILITY MODEL CONTENTS

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1: As Figures 1-10 The diagram illustrates a water tank connection structure, including a water storage tank 1 and an atomizing water tank 2 connected to the water storage tank 1. It also includes a water outlet assembly 3 connected to the water storage tank 1. The water storage tank 1 has an inner cavity 11 and an outlet 12 communicating with the inner cavity 11. The outlet assembly 3 is used to normally close the outlet 12. The atomizing water tank 2 includes a drain assembly 4 that cooperates with the outlet assembly 3 to open the outlet 12. The drain assembly 4 has a drain pipe 41 extending into the inner cavity of the atomizing water tank 2. The drain pipe 41 has an outlet end 411 near the bottom of the atomizing water tank 2, allowing water from the water storage tank 1 to flow through the outlet assembly 3, the drain pipe 41, and the outlet end 411 into the atomizing water tank 2.

[0031] This invention replaces the prior art's requirement to lengthen the outlet assembly 3 to make it closer to the bottom of the atomizing water tank 2 by providing an extended outlet pipe 41 for inserting into the atomizing water tank 2, with the outlet end of the outlet pipe 41 close to the bottom of the atomizing water tank 2. This effectively solves the problems of inconvenience in operation, increased manufacturing costs, and reduced structural strength caused by an excessively long outlet assembly 3. By replacing part of the length of the outlet assembly 3 with the outlet pipe 41, the length of the outlet assembly 3 can be shortened while ensuring that the water level in the atomizing water tank 2 can be controlled. This not only provides sufficient atomization space for the atomizing water tank 2, but also allows users to separate the water tank 1 from the atomizing water tank 2 without lifting it much, thereby improving the convenience of operation. In addition, shortening the length of the outlet assembly 3 can also reduce manufacturing costs and enhance the strength of the outlet assembly 3, reducing the risk of damage to the seal due to collision.

[0032] Specifically, the water storage tank cavity 11 is only communicated with the outside through the water outlet 12, and the water outlet assembly 3 is sealingly connected with the water outlet 12, so that when the water outlet assembly 3 is closed or filled with liquid, the water storage tank cavity 11 is in a sealed state. When the user fills the water storage tank 1 with water, the water outlet assembly 3 of the water storage tank 1 is inserted into the drain assembly 4, so that the water outlet 12 is opened, and the water in the water storage tank cavity 11 flows through the drain pipe 41 of the water outlet assembly 3, and then flows into the atomizing water tank 2 through the water outlet end 411. At this time, the water in the water storage tank cavity 11 continues to flow into the atomizing water tank 2, and when the liquid level in the atomizing water tank 2 covers the water outlet end 411, the water storage tank cavity 11 is equivalent to being in a sealed state. At this time, the water storage tank cavity 11 is still in a negative pressure state, and the air pressure in the cavity of the atomizing water tank 2 communicated with the outside is greater than that in the water storage tank cavity 11. Therefore, the water storage tank cavity 11 stops supplying water to the atomizing water tank 2. When the water in the atomizing water tank 2 is atomized and consumed, the liquid level in the atomizing water tank 2 drops, so that air can continue to enter the water storage tank cavity 11 through the water outlet end 411, so that the water in the water storage tank cavity 11 continues to flow into the atomizing water tank 2. This process is repeated continuously, so that the water storage tank 1 automatically supplies water to the atomizing water tank 2, and the liquid level in the cavity of the atomizing water tank 2 is controlled.

[0033] Further, the utility model discloses a drain pipe 41 for guiding the water in the water storage tank cavity 11 to reach the bottom of the atomizing water tank 2, so that the water flow can flow into the atomizing water tank 2 through the water outlet end close to the bottom of the atomizing water tank 2 through the drain pipe 41, which replaces the prior art of guiding water to the bottom of the atomizing water tank 2 through a long water outlet assembly 3. This setting effectively shortens the length of the water outlet assembly 3, so that the user no longer needs to lift the water storage tank 1 to a high position when taking it out, because the length of the water outlet assembly 3 is shortened, only a small lifting is needed to complete the operation of separating from the atomizing water tank 2. Further, shortening the length of the water outlet assembly 3 can also effectively reduce the manufacturing cost, so that some precise parts in the water outlet assembly 3 can be reduced in length, and then the simple structure of the drain pipe 41 is used to prolong the flow path of the water flow, thereby reducing the production cost. Further, this setting also effectively enhances the strength of the water outlet assembly 3, avoiding the damage risk caused by collision due to the long structure. Further, the water outlet end 411 close to the bottom of the atomizing water tank 2 is arranged on the drain pipe 41 extending into the atomizing water tank 2, so as to control the liquid level in the atomizing water tank 2 at the height of the water outlet end 411, thereby controlling the liquid level in the atomizing water tank 2 and ensuring that the atomizing water tank 2 has enough space for effective water atomization treatment. Further, the water outlet assembly 3 and the water outlet 12 are detachably connected, and in the embodiment, the water outlet assembly 3 and the water outlet 12 are screw connected, so as to facilitate the user to detach the water outlet assembly 3 for cleaning.

[0050] Embodiment ten: this embodiment includes all the features of embodiments one to nine, in this embodiment, when the user fills up the water in the water storage tank 1, the water outlet assembly 3 of the water storage tank 1 is inserted into the lower water outlet assembly 4, specifically, the water outlet pipe 31 is inserted into the connecting pipe 42, the first sealing part 3111 on the water outlet pipe 31 abuts against the inner wall of the connecting pipe 42, thereby forming a seal, preventing air from entering the inner cavity 11 of the water storage tank from the connection between the water outlet pipe 31 and the connecting pipe 42, at the same time, the sliding part 322 on the water outlet pipe 31 is pushed by the push part 422 on the connecting pipe 42, the sliding part 322 drives the shielding part 321 to move towards the direction of the inner cavity 11 of the water storage tank, thereby opening the water outlet 12, allowing the water flow in the inner cavity 11 of the water storage tank to flow to the inner cavity 24 of the atomization water tank through the connecting pipe 42 and the lower water pipe 41 in turn, in the process, part of the water flow will enter and be stored in the water storage sealing groove 4211, further ensuring the sealing of the connection between the water outlet pipe 31 and the connecting pipe 42. In addition, the water storage tank 1 is installed in the mounting cavity 21 of the atomization water tank 2, thereby ensuring that the water storage tank 1 will not be displaced accidentally.

When the water in the atomizing water tank inner cavity 24 is consumed, the water level in the atomizing water tank inner cavity 24 drops, so that air can continue to enter the water tank inner cavity 11 through the water outlet end of the water outlet pipeline 41, thereby causing the water in the water tank inner cavity 11 to continue to flow into the atomizing water tank inner cavity 24. This process is repeated continuously, thereby achieving the effect of automatically supplying water from the water tank inner cavity 11 to the atomizing water tank inner cavity 24 and controlling the water level in the atomizing water tank inner cavity 24.
