DETAILED DESCRIPTION

[0025] The preferred embodiments of the present application will be described below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to explain and illustrate the present application, and are not used to limit the present application.

[0026] In a first aspect, the embodiments of the present application provide an electric control box assembly structure, mainly used in devices such as pump-free water circulation humidifiers, for realizing reliable connection between the electric control system and the water tank. As shown in Figures 1 to 5 , the electric control box assembly structure mainly includes a water tank 10, an electric control box 20 and an electric control board 21. The electric control box 20 has a main control board electrically connected with the electric control board 21.

[0027] Among them, the edge of the bottom surface of the water tank 10 is provided with a groove 11 recessed towards the inside of the water tank 10. The groove 11 is arranged on the outer wall of the bottom of the water tank 10 and is recessed towards the inside of the water tank 10, used for accommodating the electric control board 21 and playing a role of positioning and protecting the electric control board 21. The shape of the groove 11 can be customized according to the actual shape of the electric control board 21 to realize a tighter fit.

[0028] The electric control box 20 is fixed on the bottom of the water tank 10 for protecting the electric control board 21 and other electronic components. In the present embodiment, the electric control box 20 can be fixed on the bottom of the water tank 10 by means of screws, buckles or adhesion, and ensure that a reliable connection is formed between the electric control box 20 and the water tank 10. In an implementation, the electric control box 20 includes a bottom cover and a face cover connected with each other, and the bottom cover is buckled with the water tank 10, so that the electric control box 20 is fixed relative to the water tank 10.

[0029] The electric control board 21 is used to control the working state of the whole humidifier. In the embodiment, the electric control board 21 is vertically arranged in the groove 11. Specifically, the electric control board 21 is inserted into the groove 11 and supported by the side wall of the groove 11, which can effectively reduce the vibration of the electric control board 21 and ensure the stability of the electric control board 21. Moreover, the main extension direction of the electric control board 21 is parallel to the depth direction of the groove 11, so that the overall structure is more compact. In specific implementation, the electric control board 21 is fixed in the groove 11 by clamping, screwing or bonding.

[0030] In the embodiment, the groove 11 is arranged at the bottom of the water tank 10, and the electric control board 21 is vertically arranged in the groove 11, so that the integration of the electric control system and the water tank 10 is realized, the volume of the electric control system is effectively reduced, and miniaturization is facilitated.

[0031] In some embodiments, as shown in Figure 6 , two clamping plates 111 are arranged in the groove 11 at intervals, and the two clamping plates 111 and the groove wall of the groove 11 form a receiving groove, and the electric control board 21 is inserted and fixed in the receiving groove. This structure can make the electric control board 21 accurately inserted into the receiving groove in the groove 11 without additional alignment operation and without the use of additional connecting parts, thereby simplifying the structure design.

[0032] In some embodiments, as shown in Figure 3 , at least one protruding rib 12 is arranged on the inner wall of the groove 11 and abuts against the surface of the electric control board 21, so that at least one side of the electric control board 21 is spaced apart from the inner wall of the groove 11 to form an air gap. The air gap can be used as an air passage to facilitate heat dissipation of the electric control board 21. In some embodiments, the protruding rib 12 abuts against the side of the electric control board 21 away from the inside of the water tank 10, so that the electric control board 21 is attached to the outer wall of the water tank 10, which is conducive to heat dissipation.

[0033] In some embodiments, as shown in Figure 3 , the height of the protruding rib 12 gradually increases along the direction in which the electric control board 21 is inserted into the groove 11. In this way, the protruding rib 12 forms an inclined surface, which can guide the electric control board 21 to be smoothly inserted into the groove 11, so as to avoid the electric control board 21 from being stuck, deviated or violently collided with the inner wall of the groove 11 during the insertion process, thereby improving the smoothness of assembly.

[0034] In some embodiments, as shown in Figure 1 , Figure 3 , at least one side wall of the groove 11 and the outer wall of the water tank 10 are in an integrated structure. This makes the product appearance more integral, without too many connection traces, has good structural strength, and can improve the overall appearance of the product.

[0035] In the second aspect, as shown in Figure 2 , Figure 4 , Figure 5As shown, the embodiment of the present application provides a pump-free water circulation mechanism, which comprises the electric control box assembly structure of any one of the first aspect embodiments, the bottom surface of the water tank 10 is detachably provided with a water inlet cover 30 and a water outlet cover 40, the opening of the water inlet cover 30 is sealingly matched with the bottom surface of the water tank 10 to form a water inlet cavity, the opening of the water outlet cover 40 is sealingly matched with the bottom surface of the water tank 10 to form a water outlet cavity, the bottom surface of the water tank 10 is provided with a water inlet port 13 communicating with the water inlet cavity and a water outlet port 14 communicating with the water outlet cavity, and a heating pipe 50 is connected between the water inlet cavity and the water outlet cavity; the water inlet cover 30 and the water outlet cover 40 are spaced apart to form a space 60, and the electric control box 20 is located in the space 60.

[0036] In the working process, when the heating pipe 50 starts to work, the water in the water inlet cavity is rapidly heated to generate high-temperature and high-pressure steam, which pushes the water to flow from the water inlet cavity to the water outlet cavity. Subsequently, the water is smoothly discharged from the water outlet port 14 in the water outlet cavity and enters other components of the humidifier for humidifying the air. When the water level in the water tank 10 gradually decreases, the water flow will return to the water inlet cavity through the water inlet port 13 under the action of gravity or negative pressure, thereby forming a new cycle. This cycle does not require the participation of a water pump, and is more energy-saving and environmentally friendly. In addition, the connection between the water inlet cover 30 and the water outlet cover 40 and the bottom of the water tank 10 adopts a detachable sealing structure, which avoids complex sealing treatment inside the water tank 10, thereby greatly reducing the risk of water leakage caused by internal sealing. At the same time, the water inlet cover 30 and the water outlet cover 40 protruding from the bottom of the water tank 10 form a space 60, so that the electric control box 20 can be stably installed in the space 60 and form a compact whole with the water tank 10. This structure design not only fully utilizes the space at the bottom of the water tank, but also makes the overall structure more compact, greatly improves the space utilization rate, realizes the integration and miniaturization of components, and meets the development trend of modern home products towards miniaturization and light weight.

[0037] In some embodiments, as shown in the drawings, Figure 5 One end of the heating pipe 50 is connected with the water inlet cavity through a first elbow 51, and the other end of the heating pipe 50 is connected with the water outlet cavity through a second elbow 52; the heating pipe 50 is received in one end of the electric control box 50, and the electric control box 50 is provided with a through hole 53 for the first elbow 51 and the second elbow 52 to extend into, thereby improving the space utilization rate and effectively improving the stability of the heating pipe 50 assembly.

[0038] In some embodiments, the water tank 10 is provided with a water level detection mechanism (not shown in the figure), which is electrically connected with the electric control board 21, and is used to send the detected water level signal to the electric control board 21 to control the opening or closing of the heating pipe 50. In this way, when the water level in the water tank 10 is too low, the water level detection mechanism will send a low water level signal to the electric control board 21, and the electric control board 21 will immediately cut off the power supply of the heating pipe 50, thereby effectively preventing dry burning caused by lack of water and avoiding safety hazards.

[0039] In a third aspect, the embodiments of the present application provide a humidifier comprising the pump-free water circulation mechanism of any one of the second aspect. Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the above-mentioned humidifier can refer to the corresponding process in the foregoing pump-free water circulation mechanism embodiments, which will not be described here.
