DETAILED DESCRIPTION

[0027] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0028] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] like Figure 1-Figure 7 As shown, this embodiment provides a water storage structure, including: a bottom shell 1, a water tank 2, and at least two detection components 3, wherein a first outlet 101 is opened on one side of the bottom shell 1; the water tank 2 is installed inside the bottom shell 1, and the water tank 2 can slide relative to the bottom shell 1, and then slide out from the first outlet 101; the two detection components 3 are arranged at intervals along the length direction of the bottom shell 1, and are located between the bottom shell 1 and the water tank 2, the detection component 3 includes a first fixed block 301, a second fixed block 302 and a pressure sensor 303, the first fixed block 301 is abutted against the bottom of the water tank 2, the second fixed block 302 is arranged on the inner bottom surface of the bottom shell 1, and the pressure sensor 303 is arranged between the first fixed block 301 and the second fixed block 302.

[0031] Based on the above scheme, a first fixed block 301 is set at the bottom of the water tank 2, a second fixed block 302 is set on the inner bottom surface of the bottom shell 1, and then a pressure sensor 303 is set between the first fixed block 301 and the second fixed block 302. The pressure sensor 303 can detect the pressure from the water tank 2 in real time, and then calculate the amount of water. When the water level is too low, the user can be reminded to add water in time. The water tank 2 and the bottom shell 1 are slidably connected, and the water tank 2 can be pulled out by pulling to add water. The water adding method is simple and convenient. It should be noted that the first fixed block 301 and the water tank 2 are in abutment relationship, not fixed connection, so the first fixed block 301 will not move with the movement of the water tank 2, and the water tank 2 will not move with the movement of the water tank 2. The gravity of the water tank 2 can be transmitted to the pressure sensor 303 through the first fixed block 301, but the first fixed block 301 is fixed, so that the pressure sensor 303 is always in a fixed state. When the pressure sensor 303 is connected through a wiring harness, the wiring harness connecting the pressure sensor 303 does not need to be pulled to avoid damage to the wiring harness. At the same time, two pressure sensors 303 are provided, and the two pressure sensors 303 can be used to detect whether the pressure values ​​on both sides of the water tank 2 are consistent, thereby assisting in determining whether the water tank 2 is installed in place. Moreover, the method of using the pressure sensor 303 to detect the water volume is more reliable than the water level sensor, because the pressure sensor 303 does not need to be immersed in water and is not easily corroded or damaged.

[0032] Furthermore, two groups of sliding components 4 are also included. The two groups of sliding components 4 are arranged at intervals, one end of which is connected to the first fixed block 301, and the other end is connected to the bottom of the water tank 2. The water tank 2 can slide relative to the bottom shell 1 through the sliding components 4. Due to the abutment relationship between the first fixed block 301 and the water tank 2, it is necessary to ensure that the water tank 2 does not affect the first fixed block 301 when it moves, and the water tank 2 can transmit weight information through the first fixed block 301 when it is stationary, so the sliding component 4 is set. The sliding component 4 at least includes a fixed part and a sliding part. The fixed part is connected to the first fixed block 301, and the sliding part is connected to the water tank 2. In this way, it can ensure the pumping and adding of water to the water tank 2, and the fixed transmission of pressure information of the first fixed block 301 can be ensured. In addition, two sliding components 4 are provided to ensure balance during movement.

[0033] In addition, based on the scheme of providing two sliding components 4, the specific structure of the first fixed block 301 needs to be adaptively adjusted to meet the installation requirements. Specifically, the first fixed block 301 includes a protrusion 3011 and an extension portion 3012 extending from both ends of the protrusion 3011 to form two sides. The sliding component 4 is installed on the extension portion 3012. The protrusion 3011 is provided with a first installation groove 3013 for the pressure sensor 303 to be embedded. The second fixed block 302 is provided with a second installation groove 3021 for the pressure sensor 303 to be embedded. The cooperation of the first installation groove 3013 and the second installation groove 3021 can ensure the stable installation of the pressure sensor 303, and the pressure sensor 303 can stably abut against the first fixed block 301 and the second fixed block 302 to complete the transmission of pressure information.

[0034] Furthermore, the sliding assembly 4 includes a slide rail 401 and a slider 402, the slide rail 401 is arranged on the first fixed block 301, the slider 402 is installed on the bottom of the water tank 2, the slider 402 is slidably matched with the slide rail 401, and the slide rail 401 is provided with a sliding groove 403 that slides with the slider 402, and the sliding groove 403 is in a T shape. In this scheme, the slider 402 and the water tank 2 are pre-fixed, the slide rail 401 and the first fixed block 301 are also pre-fixed, and similarly the bottom shell 1 and the second fixed block 302 are pre-fixed. After the above components are fixed, the first mounting groove 3013 on the first fixed block 301 is fixed to one end of the pressure sensor 303, and the other end of the pressure sensor 303 is fixed to the second fixed block 302 through the second mounting groove, thus completing the assembly of the entire water storage structure. The pre-fixing method can be fixed by screws or welding, or it can be an integrated structure.

[0035] Preferably, a gap x is provided between the bottom of the slide rail 401 and the second fixed block 302, wherein 2mm≤x<8mm. The reason for leaving a gap x between the slide rail 401 and the second fixed block 302 is to avoid failure of the pressure sensor 303. When the slide rail 401 and the second fixed block 302 are in close contact, the pressure sensor 303 will have no detectable space, or will be continuously squeezed, so that changes in the pressure value cannot be detected.

[0036] It is worth mentioning that the working principle of the pressure sensor 303 for obtaining the water level of the water tank 2 is as follows: the mass m1 of the water tank 2 and the sliding component 4 added is a constant value, the mass m2 of the added water is a variable value, the total mass is m=m1+m2, the water density ρ, the bottom surface area of ​​the water tank 2 is S, and the water level height H changes with the consumption and increase of the water volume. The user can set the minimum water volume height H1 and the maximum H2. When it is lower than H1, the value of the pressure sensor 303 triggers the set value, and the unit reminds the user to add water. When the water is added to H2, the value of the pressure sensor 303 triggers the set value to remind the customer that the water adding is complete.

[0037] During the whole process of water shortage and water addition, the water storage structure determines that no matter how the weight and position of the water tank 2 change, gravity always acts on the pressure sensor 303. When water shortage and water addition occur, gravity changes, and its numerical sensing component can be accurate to grams. According to the weight of water, the volume V1 in the water tank 2, and the initial weight m1, the chip can calculate the current water depth H. Through the H1 and H2 values ​​set by the user, the user is reminded through lights or other voice prompts that the device is short of water or has completed water addition. The depth H satisfies the following calculation formula: H = (m-m1) / ρS.

[0038] Optionally, a humidifying filter element is further included, and the humidifying filter element is arranged in the water storage tank 2 and at least partially exposed from the water storage tank 2.

[0039] On the other hand, a humidifier is also provided, comprising a water storage structure, a box body and an airflow driving assembly as described in any of the above items, wherein the water storage tank 2 structure and the airflow driving assembly are both installed in the box body, and the airflow direction driven by the airflow driving assembly passes through the water storage structure.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
