[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0031] Refer to Figures 1 to 3As shown, the embodiment of the utility model provides a humidifying device 10 for an infant incubator, which includes a humidifying water tank 100, a float assembly 200, a water pump and a heating rod 400; the humidifying water tank 100 is provided with a connected water storage chamber 111 and a heating chamber 112, and the humidifying water tank 100 is provided with a water inlet 131 connected to the water storage chamber 111 and an air outlet 121 connected to the heating chamber 112; the float assembly 200 is suspended in the water storage chamber 111 and movably connected to the humidifying water tank 100; the water pump is connected to the water inlet 131 through a pipeline, and the conductive sheet 300 connected to the water pump is connected to the humidifying water tank 100; the float assembly 200 is used to contact the conductive sheet 300 to control the water pump; the heating rod 400 is connected to the humidifying water tank 100, and the heating rod 400 is used to heat the liquid in the heating chamber 112.

[0032] When the humidifier 10 of this embodiment is used, the float assembly 200 is matched with the conductive sheet 300 of the water pump, so that the water inlet of the water pump can be linked and controlled. Compared with the magnetic matching structure in the prior art, not only the reliability is improved, but also the manufacturing cost is low and the use effect is good.

[0033] In one embodiment, the water storage chamber 111 is used to store liquid, and the float assembly 300 can be driven by the buoyancy generated by the liquid to move relative to the humidification water tank 100; Figure 3 In the arrangement state shown, as the liquid level drops, the float assembly 300 will move in the downward direction in the figure, and the float assembly 300 is separated from the conductive sheet 300. When the liquid level rises, the float assembly 300 will move in the upward direction in the figure until it contacts the conductive sheet 300.

[0034] Specifically, the humidifying water tank 100 is provided with a guide hole 132 connected to the water storage chamber 111; the float assembly 200 includes a float member 210 and a guide rod 220, the guide rod 220 is passed through the guide hole 132 and is slidably connected to the humidifying water tank 100, the float member 210 is suspended in the water storage chamber 111, and one end of the guide rod 220 is connected to the float member 210, and the other end of the guide rod 220 is used to contact or separate from the conductive sheet 300.

[0035] With this setting, when the water flow inside the humidifying water tank 100 does not reach the preset amount, the float member 210 is separated from the conductive sheet 300. At this time, the water pump starts and pumps water into the humidifying water tank 100 through the pipeline. As the water volume in the humidifying water tank 100 increases, the float member 210 drives the guide rod 220 to move towards the conductive sheet 300 under the action of buoyancy. At this time, the cooperation between the guide rod 220 and the guide hole 132 can guide the movement of the guide rod 220 until the guide rod 220 contacts the conductive sheet 300. After the guide rod 220 contacts the conductive sheet 300, the water pump can be controlled to stop, so as to stop pumping water into the humidifying water tank 100. By driving the guide rod 220 to move relative to the humidifying water tank 100 with the float member 210, the function of controlling the start and stop of the water pump can be realized.

[0036] In an embodiment, the guide rod 220 includes a guiding portion 221 and a contacting portion 222. The guiding portion 221 is respectively connected to the float member 210 and the contacting portion 222, and the guiding portion 221 is in sliding fit with the guide hole 132; the number of conductive sheets 300 is at least two, and the contacting portion 222 is used to contact and electrically connect with at least two of the conductive sheets 300.

[0037] In this embodiment, the guiding portion 221 is used to be in sliding fit with the guide hole 132, and the diameter of the contacting portion 222 is not less than that of the guiding portion 221. Thus, the contact area of the guide rod 220 can be increased. When the number of conductive sheets 300 is two, when the water volume in the humidifying water tank 100 reaches the preset amount, the contacting portion 222 can contact the two conductive sheets 300 simultaneously to realize the function of controlling the start and stop of the water pump. At the same time, when the guiding portion 221 and the contacting portion 222 are of a split structure, or the guiding portion 221 and the float member 210 are of a split structure, the float member 210 can be first placed inside the humidifying water tank 100, and the guiding portion 221 can be inserted into the guide hole 132 and connected to the float member 210. Thus, the assembly of the float assembly 200 can be completed, with a simple structure and convenient disassembly and assembly. At the same time, the float member 210 and the guide rod 220 can also be made of different materials. For example, the float member 210 is made of plastic material to improve the buoyancy of the float member 210, and the contacting portion 222 is made of metal to realize the conductive function of the guide rod 220.

[0038] Preferably, the width of the contacting portion 222 is greater than that of the guiding portion 221, and the orthographic projection of the guide hole 132 on the contacting portion 222 is located inside the contacting portion 222.

[0039] With this setting, after the contacting portion 222 moves towards and contacts the conductive sheet 300, the contacting portion 222 can contact multiple conductive sheets 300 simultaneously, so that the multiple conductive sheets 300 are electrically connected to each other to realize the function of controlling the start and stop of the water pump.

[0040] Specifically, the number of the conductive sheets 300 is two, and the two conductive sheets 300 are respectively connected to the water pump; the two conductive sheets 300 are symmetrically arranged with respect to the central axis of the guiding hole 132.

[0041] It can be understood that the guide rod 220 can serve as the control circuit of the water pump. After the guide rod 220 contacts the conductive sheet 300, the water pump can be controlled to short-circuit. When the contact part 222 is separated from the conductive sheet 300, the water pump starts and pumps water into the water storage cavity 111. Specifically, the number of the conductive sheets 300 can also be one. In this case, the other end of the float assembly 200 needs to be connected to the background circuit board to connect the circuit after floating.

[0042] Preferably, the float member 210 is internally provided with a cavity. In this embodiment, by providing a cavity in the float member 210, the buoyancy of the float member 210 in water can be effectively improved. Of course, the interior of the float member 210 can also be a filling structure, filled with the material of the float member 210 itself, or a material with a density less than that of the float member 210, which is not uniquely limited herein.

[0043] Specifically, the humidifying water tank 100 includes a water tank body 110, an air outlet cover 120 and a water tank cover 130. The water tank cover 130 and the air outlet cover 120 are respectively detachably connected to the water tank body 110. A water storage cavity 111 and a heating cavity 112 are arranged in the water tank body 110. An accommodation cavity 133 with a width greater than that of the guiding hole 132 is further formed on one side of the water tank cover 130 facing the water storage cavity 111. The float member 210 is slidably matched with the accommodation cavity 133. The water inlet 131 and the guiding hole 132 are both arranged on the water tank cover 130, and the air outlet 121 is arranged on the air outlet cover 120.

[0044] In this embodiment, after a preset amount of water is stored in the water storage cavity 111, the water flow in the water storage cavity 111 can be heated by starting the heating rod 400 to generate steam, and the steam can be discharged through the air outlet 121 of the air outlet cover 120. During the assembly process, the water tank body 110 and the water tank cover 130 can be separated to install the float assembly 200 on the water tank cover 130. Specifically, the water tank body 110 can be made of aluminum alloy materials (such as ADC12, DM32, AL6061, Al Si 10Mg, etc.), and the surface is subjected to hard anodizing treatment, having wear resistance, corrosion resistance, weather resistance, insulation, etc. The air outlet cover 120 is made of silica gel material, and the water tank cover 130 and the float member 210 are made of high-temperature resistant plastics (such as PPSU, PSU, PEI, etc.). The guide rod 220 and the conductive sheet 300 can be made of stainless steel materials (such as 304 stainless steel, 316 stainless steel, 303 stainless steel, etc.).

[0045] Further, the float member 210 includes a limiting portion 211 and a float portion 212. The limiting portion 211 is respectively connected to the float portion 212 and the guide rod 220. The limiting portion 211 is in sliding fit with the accommodating cavity 133, and the width of the float portion 212 is greater than the width of the accommodating cavity 133.

[0046] In this embodiment, by providing the cooperation between the limiting portion 211 and the accommodating cavity 133, the accommodating cavity 133 can guide and limit the movement of the limiting portion 211 to prevent the limiting portion 211 from disengaging from the accommodating cavity 133 and affecting the movement track of the float assembly 200. Meanwhile, after the float member 210 moves to the uppermost position in the water storage cavity 111, the water tank cover 130 can abut against the limiting portion 211.

[0047] Specifically, the humidifying water tank 100 further includes a sealing member 140. The sealing member 140 is disposed around the air outlet cover 120 and is detachably connected to the humidifying water tank 100. The sealing member 140 is used to seal between the air outlet cover 120 and the water tank body 110.

[0048] In this embodiment, the sealing member 140 is preferably a hose clamp. After the water tank cover 130 is connected to the water tank body 110, by sleeving the hose clamp on the water tank cover 130 and then adjusting the hose clamp, the water tank cover 130 and the water tank body 110 can be sealed, and the disassembly and assembly are convenient.

[0049] The present utility model further provides an incubator for infants, which includes a culture container and the humidifying device 10 in any one of the above embodiments; the air outlet 121 of the humidifying device 10 is connected to the culture container.
