[0023] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:

Compared with the traditional rigid contact method for electrical connection, this method is less affected by the tightness of the upper and lower shells, thus ensuring a stable electrical connection between the water level detection device and the conductive electrode. The water level detection device can then detect the water level through the conductive electrode. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] The existing water level detection devices for humidifiers have the following defects and shortcomings in actual use: When the water level sensor and the power supply or control device are installed on the upper and lower shells respectively, the upper shell needs to be opened before and after use for operations such as adding water, and it is inconvenient to open and operate by connecting cables in the traditional way; when using contact plates for connection, the tightness of the connection is affected by the degree of fit between the upper and lower shells, resulting in problems with unstable and inaccurate connection.

[0034] To address the aforementioned technical problems, this embodiment provides a humidifier. (See reference...) Figures 1 to 3 As shown, Figure 1 This is an exploded view of the humidifier in an embodiment of this application. Figure 2 This is a schematic diagram of the connection between the mounting bracket and the lower housing in an embodiment of this application. Figure 3 This is a schematic diagram of the connection between the conductive electrode and the mounting bracket in an embodiment of this application.

[0035] The humidifier provided in this embodiment includes: a water level detection device 1, a mounting bracket 2, a conductive electrode 3, an upper shell 4, and a lower shell 5.

[0036] The water level detection device 1 is connected to the upper housing 4 and is provided with a detection electrode 10 for detecting the water level. For example, the water level detection device 1 and the upper housing 4 are connected by existing connection methods such as screws or clips.

[0037] The mounting bracket 2 is connected to the lower housing 5 and has a mounting groove 21 extending along the height direction, and a clearance hole 22 communicating with the upper end of the mounting groove 21.

[0038] The conductive electrode 3 is disposed in the mounting groove 21 and connected to the mounting bracket 2. The top of the conductive electrode 3 has an elastic protrusion 31 exposed in the relief hole 22. The elastic protrusion 31 has the deformation capability of elastically restoring itself after being compressed. It is understood that the conductive electrode 3 is conductive and can be made of metal.

[0039] The upper housing 4 is detachably mounted on the lower housing 5; wherein, when the upper housing 4 is mounted on the lower housing 5, the detection electrode 10 is pressed onto the elastic protrusion 31 of the conductive electrode 3, so that the water level detection device 1 is electrically connected to the conductive electrode 3.

[0040] The humidifier installation process of this application is as follows: First, connect the water level detection device 1 to the upper housing 4, fix the water level detection device 1 in the predetermined position of the upper housing 4, and ensure that the detection electrode 10 can be correctly aligned and contact the conductive electrode 3 to be installed later. Then, install the conductive electrode 3: insert the conductive electrode 3 into the mounting groove 21 of the mounting bracket 2, and ensure that it is firmly fixed in the mounting groove 21, with the elastic protrusion 31 at the top of the conductive electrode 3 protruding from the clearance hole 22. Next, set the mounting bracket 2 and the conductive electrode 3: connect the mounting bracket 2 to the lower housing 5, and ensure that the bracket is firmly installed on the lower housing 5. Finally, assemble the upper housing 4 and the lower housing 5: align the upper housing 4 with the lower housing 5, and prepare to close the cover. During the closing process, ensure that the detection electrode 10 of the water level detection device 1 on the upper housing 4 can be accurately pressed onto the elastic protrusion 31 of the conductive electrode 3.

[0041] When the humidifier of this application is in operation, the upper and lower shells are closed, and water is injected into the humidifier. As the water level rises, the water comes into contact with the conductive electrode 3. Due to the elastic protrusion 31's ability to elastically return to its original shape after being pressed, it can maintain good contact with the detection electrode 10. Subsequently, electrical connection and signal transmission are performed: when the detection electrode 10 is pressed onto the elastic protrusion 31 of the conductive electrode 3, an electrical connection is established between the water level detection device 1 and the conductive electrode 3. As the water level changes, the state of this electrical connection also changes, thereby triggering the water level detection device 1 to send a corresponding signal. Finally, signal processing and control are performed: the humidifier's control system receives the signal from the water level detection device 1. Based on the signal changes, the control system can determine the current water level status and adjust the humidifier's operating parameters accordingly, such as the humidification amount and the switching of the water pump.

[0042] The humidifier of this application uses a water level detection device 1 in conjunction with a conductive electrode 3 to detect the water level and improves the ease of opening and closing the upper housing 4. Specifically, the water level detection device 1 is connected to the upper housing 4, and the conductive electrode 3 is connected to the lower housing 5 via a mounting bracket 2, forming two independent parts. Compared with the design of existing water level sensors, this design makes the opening and closing of the upper housing 4 much more convenient. Equally important, when the upper housing 4 is placed on the lower housing 5, the detection electrode 10 is pressed against the elastic protrusion 31 of the conductive electrode 3. Because the elastic protrusion 31 has elastic deformation capability, it can ensure full contact with the detection electrode 10, achieving a stable electrical connection between the water level detection device 1 and the conductive electrode 3, allowing the water level detection device 1 to detect the water level through the conductive electrode 3. The water level detection principle of this application is the same as that of existing electrode-type water level detection devices. Specifically, the working principle of the electrode-type water level detection device is based on the conductivity of the liquid. When the conductive electrode 3 is immersed in the liquid, a conductive path will be formed between the electrodes due to the conductivity of the liquid, thereby generating a current or voltage signal. This signal can be converted into an electrical signal and displayed through a secondary instrument or indicator light, thereby realizing the measurement and monitoring of the water level.

[0043] In one embodiment where the conductive electrode 3 is connected to the mounting bracket 2, see [reference needed]. Figure 3 As shown, the mounting bracket 2 has a horizontally extending connecting shaft 23 inside the mounting groove 21. The conductive electrode 3 has several loops 32 at the lower end of the elastic protrusion 31, and these loops are fitted onto the connecting shaft 23 to connect the conductive electrode 3 to the mounting bracket 2. When the upper housing 4 is placed on the lower housing 5, the detection electrode 10 is pressed onto the elastic protrusion 31 of the conductive electrode 3, and the conductive electrode 3 is supported on the connecting shaft 23 by the loops 32, thus ensuring the stability of the structure.

[0044] For example, see Figure 3 As shown, the conductive electrode 3 is formed into a collar 32 by spiral bending. At the end of the collar 32, the conductive electrode 3 extends outward in the spiral bending direction to form an elastic protrusion 31. That is, the elastic protrusion 31 and the collar 32 are offset from each other at a top view angle, which improves the elastic deformation capability of the connection part 27 of the elastic protrusion 31 and the collar 32, so that the elastic protrusion 31 can make more sufficient contact with the detection electrode 10 when compressed.

[0045] To further improve the structural stability of conductive electrode 3, see [reference needed]. Figure 3 As shown, see reference Figure 2 As shown, the mounting bracket 2 has a limiting post 24 directly below the connecting shaft 23. The conductive electrode 3 extends downward from the first end of the collar 32 and is positioned on the side of the limiting post 24 away from the elastic protrusion 31. The conductive electrode 3 can be limited by the limiting post 24, preventing it from deflecting or deforming in the direction of the limiting post 24.

[0046] In one embodiment where the mounting bracket 2 is connected to the lower housing 5, see [reference needed]. Figure 2 As shown, the inner side of the lower housing 5 has a slot 51 extending along the height direction, with the opening 29 of the slot 51 facing upwards. The bottom end of the mounting bracket 2 has a pin 25, which is inserted into the slot 51. The top of the lower housing 5 has a protrusion 52 protruding inwards, and the top of the mounting bracket 2 has a groove 26. The protrusion 52 is inserted into the groove 26 and connected to the groove 26 by a snap-fit. During installation, the mounting bracket 2 is first inserted into the slot 51 by the pin 25, and then pushed towards the protrusion 52, so that the protrusion 52 and the groove 26 are engaged by the snap-fit, thus fixing the mounting bracket 2. Disassembly is simply done by reversing the operation. This fixing method has the advantages of convenient assembly and disassembly and a firm connection. The cooperation between the groove 26 and the protrusion 52 can both limit the position of the mounting bracket 2 and serve as a positioning structure for the mounting bracket 2, making it easy for users to quickly find the installation position of the mounting bracket 2 on the lower housing 5.

[0047] For easier disassembly of bracket 2, please refer to... Figure 2 and Figure 3 As shown, the top of the mounting bracket 2 has two grooves 26, and a connecting portion 27 is formed between the grooves 26. The connecting portion 27 has the ability to elastically return to its original shape after being pressed. The connecting portion 27 is provided with an operating protrusion 28, which is used to press down and pull the connecting portion 27 to disengage the snap-fit ​​between the protrusion 52 and the groove 26. The cooperation of the two pairs of grooves 26 and the protrusion 52 can improve the firmness of the connection between the mounting bracket 2 and the lower housing 5. At the same time, the opening of the two grooves 26 facilitates the formation of the connecting portion 27 with elastic deformation capability, so that when the operating protrusion 28 presses down and pulls the connecting portion 27, the connecting portion 27 can generate a large deformation, making it easier to disengage the snap-fit ​​between the protrusion 52 and the groove 26. When the upper and lower housings are closed, the operating protrusion 28 also cooperates with the concave point of the upper housing 4 to realize the point-to-point cooperation between the upper and lower housings and improve the stability of the connection between the upper and lower housings.

[0048] For example, see Figure 3 As shown, there are two sets of mounting groove 21, clearance hole 22, conductive electrode 3 and detection electrode 10. The two sets of mounting groove 21, clearance hole 22, conductive electrode 3 and detection electrode 10 are symmetrically arranged with the vertical plane passing through the operation protrusion 28 as the center, so as to improve the uniformity of force on the mounting bracket 2 and conductive electrode 3.

[0049] To make full use of the space between the two mounting slots 21 of the mounting bracket 2, see [reference] Figure 2 and Figure 3As shown, the mounting bracket 2 has an opening 29 between two mounting slots 21, and a cover plate 6 is rotatably connected to the inside of the opening 29 via a pivot. The cover plate 6 is used to open and close the opening 29, and is provided with a water guide groove 60 and a handle for controlling the rotation of the cover plate 6. The water guide groove 60 is used to add water into the lower housing 5 when the cover plate 6 opens the opening 29.

[0050] For example, the water channel is formed by the cover plate 6 body and the side walls on both sides, and its cross-section has a U-shaped structure.

[0051] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
