Description

Technical Field

[0001] This utility model relates to the field of baby care box technology, specifically to a steam humidification device and a baby care box. Background Technology

[0002] Most baby incubators on the market are equipped with humidifiers, which provide water vapor to the inside of the incubator to maintain appropriate and balanced humidity, thus ensuring a suitable environment for infants.

[0003] Existing humidifiers typically include a water tank, a heating element, and a nozzle. External water flows into the water tank through a control valve. The heating element heats the water to generate steam, which is then sprayed into the inner cavity of the incubator through the nozzle, thus achieving humidification. After prolonged use, humidifiers usually require cleaning. Existing humidifiers are mainly divided into internal and external installations. Internally installed humidifiers cannot be directly opened from the outside, making them difficult to clean. Therefore, they need to be equipped with self-cleaning devices. However, the cleaning effect of self-cleaning devices is limited and cannot effectively prevent the accumulation of dirt. For externally installed humidifiers, cleaning requires disassembling and reassembling the entire water tank, which is more cumbersome and affects cleaning efficiency. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1:

[0035] This utility model provides a steam humidification device, see reference. Figures 1 to 8 As shown, the steam humidification device includes a water tank assembly 1, a heating assembly 2, and a steam nozzle assembly 3.

[0036] The water tank assembly 1 is provided with a water storage chamber 111 for storing water. One end of the water tank assembly 1 is connected to the water storage chamber 111 and has an opening. The opening is located inside the humidification chamber of the main body of the humidification device. The heating assembly 2 is provided in the water storage chamber 111 for generating water vapor. The steam nozzle assembly 3 is detachably inserted into the water storage chamber 111 along the opening and covers the opening.

[0037] During operation, water flows into the water storage chamber 111, and the heating component 2 heats the water to generate steam. The steam is then sprayed into the humidification chamber through the steam nozzle assembly 3.

[0038] During the aforementioned humidification process, the water tank assembly 1, the heating assembly 2, and the steam nozzle assembly 3 work together to achieve a significant humidification effect.

[0039] During cleaning, the user removes the steam nozzle assembly 3 from inside the humidification chamber. After that, the water tank assembly 1 and heating assembly 2 on the main body of the equipment can be cleaned, as can the removed steam nozzle assembly 3.

[0040] During the aforementioned cleaning process, users do not need to disassemble the water tank assembly 1; they can simply remove the steam nozzle assembly 3 for cleaning. This not only makes disassembly and assembly convenient and efficient but also yields significant cleaning results.

[0041] Example 2:

[0042] Example 2 is based on Example 1:

[0043] like Figures 1 to 8 As shown, the steam humidification device includes a water level control component 4, which is installed on the water tank assembly 1 and is used for real-time control of the water level in the water storage chamber 111.

[0044] The water level control component 4 includes a water level probe. The upper water level detection end 41 and the lower water level detection end 42 of the water level probe are both disposed in the water storage chamber 111. The upper water level detection end 41 is located above the lower water level detection end 42. The upper water level detection end 41 and the lower water level detection end 42 are used for detecting the upper water level and the lower water level, respectively.

[0045] When the water level detection end 42 detects that the water storage chamber 111 is below the lower water level, water is promptly added to the water storage chamber 111.

[0046] When the upper water level detection end 41 detects that the water storage chamber 111 has reached the upper water level, the water intake stops.

[0047] The water level control component 4 can effectively control the water level inside the water storage chamber 111, so that its water capacity is always kept within a suitable range.

[0048] As an optional implementation, the steam nozzle assembly 3 includes a nozzle body 31 and a steam pipe 32.

[0049] The nozzle body 31 is connected to the first end of the steam pipe 32. The nozzle body 31 covers the opening. The nozzle body 31 serves as a nozzle for spraying steam and also functions as a water tank cover for sealing the water storage chamber 111.

[0050] The second end of the steam pipe 32 is detachably inserted into the water tank assembly 1 along the opening. The end wall of the second end of the steam pipe 32 is provided with a connecting groove 321 that communicates with the water storage chamber 111. The connecting groove 321 is a groove, and the number of such grooves is at least one.

[0051] In actual operation, the water first enters the water storage chamber 111, and then enters the steam pipe 32 through the connecting groove 321. The connecting groove 321 is located at the second end of the steam pipe 32, which is the bottom end. This effectively ensures that the water can smoothly enter the steam pipe 32.

[0052] The heating component 2 is inserted into the steam pipe 32. The heating component 2 mainly heats the water inside the steam pipe 32. The generated steam enters the nozzle body 31 through the first end and is then sprayed into the humidification chamber by the nozzle body 31.

[0053] As an optional implementation, the first end of the steam pipe 32 is provided with an end plate, which is a conical plate protruding toward the nozzle body 31. The end plate is provided with a connecting hole that communicates with the nozzle body 31, and steam enters into the nozzle body 31 through the connecting hole.

[0054] The connecting holes include a central connecting hole 3211 and an edge connecting hole 3212. The central connecting hole 3211 is located in the middle of the end plate, and the number of edge connecting holes 3212 is set to multiple, with all edge connecting holes 3212 being evenly opened along the circumferential direction at the edge of the end plate.

[0055] The combination of the porous structure and the conical plate can effectively ensure the connection effect, allowing the rising steam to smoothly enter the nozzle body 31. On the other hand, it has a guiding function, facilitating the downward flow of condensate on the end plate. At the same time, it can also puncture the water bubbles rising during the heating process, preventing water bubbles from being sprayed out of the nozzle body 31, thus ensuring the humidification effect.

[0056] As an optional implementation, the base 12 of the water tank assembly 1 is provided with a plug-in boss 121, and the second end port of the steam pipe 32 is sized to match the plug-in boss 121, and the plug-in boss 121 is inserted into the second end port of the steam pipe 32.

[0057] The steam nozzle assembly 3 can be disassembled and assembled simply by plugging and unplugging, further facilitating cleaning operations.

[0058] As an optional implementation, the first end of the steam pipe 32 is inserted into the port of the nozzle body 31; a snap-fit ​​part 323 is provided on the outer wall of the first end of the steam pipe 32, and a snap-fit ​​part 311 is provided on the inner wall of the port of the nozzle body 31, and the snap-fit ​​part 323 and the snap-fit ​​part 311 are snap-fitted together.

[0059] Specifically, the snap-fit ​​part 323 is configured as an annular snap-fit ​​protrusion, and the snap-fit ​​part 311 is configured as an annular snap-fit ​​groove. The two are compatible and adopt a snap-fit ​​structure, which makes assembly convenient.

[0060] At least one annular sealing protrusion 322 is provided on the outer peripheral wall of the first end of the steam pipe 32.

[0061] Specifically, the number of annular sealing protrusions 322 is set to multiple, and all annular sealing protrusions 322 are arranged evenly along the axial direction of steam pipe 32. In this way, multiple line seals can be formed, and the sealing effect is significant.

[0062] As an optional implementation, the water tank assembly 1 includes a water tank body 11 and a base 12.

[0063] The opening is located at one end of the water tank body 11, and the base 12 is detachably located at the other end of the water tank body 11. Specifically, the base 12 is connected to the water tank body 11 by threaded fasteners.

[0064] The water tank body 11 is provided with an inlet 112 and a drain 113 that are connected to the water storage chamber 111. The inlet 112 and the drain 113 are used for water intake and water outlet of the water storage chamber 111, respectively.

[0065] A first sealing element 13 is provided between the water tank body 11 and the base 12; a second sealing element 14 is provided between the water tank body 11 and the steam nozzle assembly 3. Both the first sealing element 13 and the second sealing element 14 are sealing rings, which cooperate with each other to further ensure the sealing effect of the water tank assembly 1.

[0066] As an optional implementation, the base 12 is provided with a mounting groove 122, which is shaped to match the heating rod 21 of the heating assembly 2.

[0067] Specifically, the mounting groove 122 is a blind groove, and an mounting sleeve is provided on the base 12 along the axial direction. The mounting sleeve is inserted into the steam pipe 32. The mounting sleeve, the steam pipe 32 and the water tank body 11 are coaxially arranged, and the mounting groove 122 is opened on the end face of the mounting sleeve along the axial direction.

[0068] The heating assembly 2 includes a heating rod 21 and a temperature control switch 22. The heating rod 21 is inserted into the mounting slot. The temperature control switch 22 is mounted on the base 12 and is electrically connected to the heating rod 21. The temperature control switch 22 is used to control the opening and closing of the heating rod 21.

[0069] In practical applications, the water tank body 11 and the base 12 can also be set as an integrated structure. Furthermore, the heating rod 21 can also be integrated onto the base 12, so that the water tank body 11, the base 12 and the heating rod 21 form a single part.
