DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] On the one hand, the utility model provides a humidifying device that can evaporate liquid into steam to humidify equipment that needs humidification. In this embodiment, humidification of infant care equipment is used as an example for explanation. In one embodiment, please refer to Figure 1 The humidifying device comprises a housing 1, a water tank assembly 3, an injection assembly 5 and a water storage assembly 2. The housing 1 is the whole of the humidifying device, and the housing 1 can be used as a supporting structure, can also play a role in protecting parts, and can also provide an assembly environment for the assembly of parts.

[0037] The water tank assembly 3 is arranged on the housing 1, and the water tank assembly 3 has a water-containing box 31 and a heating block 33. Generally, the liquid evaporated inside the humidification structure is mainly water. Of course, in some cases, the evaporated liquid can also be other liquids such as solutions with added fragrances. This application takes the water contained in the box 31 as an example for explanation. When the heating block 33 is powered on, it can heat the water in the box 31, thereby promoting the evaporation of the water.

[0038] The jet assembly 5 has a jet channel 52, one end of the jet assembly 5 is connected to the box body 31 through the jet channel 52, and the other end is connected to the equipment to be humidified. The jet channel 52 connected to the box body 31 is located on the path of steam flow, so that the steam can flow into the equipment to be humidified along the jet channel 52, thereby humidifying the equipment to be humidified.

[0039] The water storage component 2 can be installed on the box body 31, and the water storage component 2 can store a certain amount of water to continuously provide the water required for evaporation in the water tank. The water storage component 2 has a water outlet 2311, and the water storage component 2 includes a blocking structure 25, which can move toward and away from the water outlet 2311. The blocking structure 25 is elastically arranged. Under normal conditions, the blocking structure 25 can block the water outlet 2311 under the action of elastic force. When the water storage component 2 is installed on the box body 31, the position of the blocking structure 25 on the box body 31 can drive the blocking structure 25 to move away from the water outlet 2311 to open the water outlet 2311.

[0040] The water outlet 2311 can be connected to the space where the heating block 33 is located, and in the direction of gravity, the lowest water level of the water storage component 2 is higher than the lowest water level of the space where the heating block 33 is located. It should be noted that the gravity direction is the direction of gravity to which the liquid in the water storage component 2 and the box 31 is subjected when the water storage component 2 is connected to the box 31 and the entire humidifying device is installed to the equipment to be humidified.

[0041] Depend on Figure 1 It can be seen that the direction from H to L in the figure is the direction of gravity. Figure 1 It can also be seen that the dotted line A is the lowest water level of the water storage assembly 2. Generally, the position of the water outlet 2311 is flush with the lowest water level, or lower than the lowest water level (e.g. Figure 1 ), so the lowest water level is the location of the water outlet 2311. In this embodiment (such as Figure 1 ), water level line A is also the water level line of the water outlet 2311. The dotted line B in the figure is the lowest water level in the space where the heating block 33 is located.

[0042] By setting the blocking structure 25, the water outlet 2311 can be blocked under the action of elastic force, so that the liquid in the water storage component 2 is not easy to flow out. When the water storage component 2 is installed in the box body 31, the blocking structure 25 can be driven to separate from the water outlet 2311 through the driving of the internal structure of the box body 31 to open the water outlet 2311, so that the liquid inside the water storage structure can flow into the box body 31 from the water outlet 2311, so as to achieve the effect of automatically opening the water storage component 2. In addition, the lowest water level of the water storage component 2 is higher than the lowest water level of the space where the heating block 33 is located. In this way, there is a pressure difference between the space where the water storage component 2 and the heating block 33 are located, so that the liquid in the water storage component 2 can automatically flow to the area where the heating block 33 is located to achieve heating and evaporation.

[0043] When the height of the liquid in the area where the heating block 33 is located is consistent with the height of the water outlet 2311, due to the pressure balance, the liquid is stopped from being transported into the box 31. When the heating block 33 heats and evaporates the liquid in the box 31, causing the liquid level in the box 31 to be lower than the water outlet 2311, a pressure difference will be formed again, and the liquid in the water storage component 2 can flow back into the box 31 until the water level of the liquid in the box 31 is flush with the water outlet 2311 again. In this way, by setting the blocking structure 25, the water outlet 2311 can be automatically opened when the water storage component 2 is installed, so that the liquid can flow out from the water outlet 2311. By setting the water level in the water storage component 2 and the box 31, the pressure difference can be used to realize that the liquid is automatically added from the water storage component 2 to the box 31. In this way, the amount of liquid to be evaporated can be increased by the water storage component, and the liquid stored in the water storage component can automatically flow into the water tank for heating, thereby reducing the frequency of adding water to the water tank and ensuring the humidification effect.

[0044] In one embodiment, see Figure 1 and Figure 2 The water storage assembly 2 includes a water storage tank 21, and the water storage tank 21 is provided with an opening 4223, and the opening 4223 is used to pour water into or out of the water storage tank 21. The end surface of the water storage tank 21 where the opening 4223 is located is set as an inclined surface, and the position where the opening 4223 is located is lower than the other positions, so that the end surface of the water storage tank 21 is gathered toward the opening 4223, so that the liquid can fully flow out from the opening 4223. The water storage tank 21 is also provided with a screw connection portion 22 at the position of the opening 4223, and a screw cover 23 is threadedly connected to the screw connection portion 22. The screw cover 23 can cover the opening 4223 of the water storage tank 21, but the water outlet 2311 is provided on the screw cover 23, so that the water storage tank 21 can still communicate with the outside through the water outlet 2311, and the blocking structure 25 is connected to the screw cover 23, and the water outlet 2311 can be blocked under normal conditions, so that the water storage tank 21 is in a closed state with the outside under normal conditions.

[0045] In a specific embodiment, the rotary cover 23 has a cover plate 231 and a side plate 232. The side plate 232 is arranged around the peripheral wall of the cover plate 231. The inner wall of the side plate 232 has a threaded structure. The outer wall of the screw-on portion 22 is provided with a threaded structure, so that the side plate 232 can be threadedly connected with the screw-on portion 22. The cover plate 231 of the rotary cover 23 is provided with a groove 2312 in the direction facing away from the water storage tank 21. The water outlet 2311 is provided through the bottom of the groove 2312. The bottom of the groove 2312 is also provided with a plug hole 2313. The opening direction of the plug hole 2313 is consistent with the opening direction of the groove 2312. Part of the blocking structure 25 can be inserted into the insertion hole 2313, so that the blocking structure 25 can move along the opening path of the insertion hole 2313. Under normal circumstances, part of the blocking structure 25 is pressed against the opening 4223 of the groove 2312 under the action of elastic force, so as to block the groove 2312, so that the water outlet 2311 and the interior of the water storage tank 21 are separated. Under the action of external force, the blocking structure 25 can move in the direction opposite to the elastic force to open the groove 2312.

[0046] In a more specific embodiment, the sealing structure 25 includes a pin 252 and a plug 251 and a top head 2521 arranged at both ends of the pin 252. The pin 252 can be inserted into the socket 2313. At this time, the plug 251 and the top head 2521 are located on different sides of the cover plate 231, the plug 251 and the groove 2312 are located on the same side, and the top head 2521 is located on the other side. When the pin 252 moves in the socket 2313, the outer wall of the plug 251 can be attached to the edge of the opening 4223 of the groove 2312 to seal the groove 2312.

[0047] The ejector pin 252 is also sleeved with an elastic member 253, which is preferably a spring. The elastic member 253 is arranged between the top head 2521 and the cover plate 231 of the rotary cover 23. Under normal conditions, the elastic member 253 is in a compressed state, or in a state of neither stretching nor compressing. The end of the elastic member 253 abuts against the top head 2521, so that the plug 251 can abut against the opening 4223 of the groove 2312. When a force is applied to the top head 2521 to squeeze the elastic member 253 and the force is large enough, the ejector pin 252 can be moved, thereby driving the plug 251 to be separated from the groove 2312.

[0048] It should be noted that the shape of the plug 251 is not limited, and it only needs to seal the opening 4223 of the groove 2312. In this embodiment, the circumferential shape of the plug 251 is consistent with the shape of the opening 4223 of the groove 2312, and the circumferential size of the plug 251 gradually increases from the end close to the ejector pin 252 to the end away from the ejector pin 252. The size of the end of the plug 251 close to the ejector pin 252 is smaller than the size of the opening 4223 of the groove 2312, and the size of the end of the plug 251 away from the ejector pin 252 is larger than the size of the opening 4223 of the groove 2312. The plug 251 is configured in this way so that the smaller end of the plug 251 can serve as a guide, making it easier for its peripheral wall to fit at the opening 4223 of the groove 2312.

[0049] Preferably, the groove 2312 is cylindrical, the plug 251 is truncated, the plug hole 2313 is also a circular hole, the axis of the plug hole 2313 coincides with the axis of the groove 2312, and the water outlet 2311 is arranged around the plug hole 2313. A sealing member 24 is also arranged at the connection position between the cover plate 231 and the side plate 232. The sealing member 24 is preferably a sealing rubber or a silicone ring. When the side plate 232 and the screw-on part 22 are threadedly connected, the end of the screw-on part 22 can be pressed against the sealing member 24 to increase the sealing between the screw cover 23 and the screw-on part 22.

[0050] In a specific embodiment, please combine Figure 3 A surrounding plate 233 is provided at one end of the cover plate 231 facing away from the water storage tank 21, and the surrounding plate 233 encloses the water outlet 2311. A plurality of water level grooves 2331 penetrate the peripheral wall of the surrounding plate 233. The water level grooves 2331 can connect the space enclosed by the surrounding plate 233 with the space where the heating block 33 is located, and then the water outlet 2311 can be connected to the area where the heating block 33 is located through the water level grooves 2331.

[0051] It should be noted that, in the direction of gravity, the end of the water level trough 2331 close to the water storage tank 21 is higher than the lowest water level in the area where the heating block is located, and lower than the height of the water outlet 2311. In this way, the water at the water outlet 2311 can flow into the area enclosed by the enclosure 233, and then flow out from the water level trough 2331 to enter the area where the heating block 33 is located.

[0052] It is worth mentioning that the end of the water level tank 2331 close to the water storage tank 21 can be regarded as being located at the water level line C. Figure 1 The dashed line C shown is composed of Figure 1It can be seen that water level A is higher than water level C, and water level C is higher than water level B. When water is added to the box body 31 through the water tank 21, water flows out from the water outlet 2311, and then flows into the area where the heating block 33 is located through the water level groove 2331. When the water level in the water tank gradually rises to the same as the water level C, the water surface in the water tank and the water in the water tank 21 will close the area between the water level A and the water level C. The water in the water tank 21 can no longer continue to flow out from the water outlet 2311 due to the atmospheric pressure, and a balanced state is maintained at this time. When the heating block 33 in the water tank is heated, the water in the water tank evaporates and rises, and the water in the water tank decreases little by little. At this time, the water in the water tank 21 will also flow into the water tank little by little until a balanced state is reached.

[0053] In one embodiment, please combine Figures 4 to 6 The box body 31 includes an upper cover 311 and a lower cover 313, and the upper cover 311 and the lower cover 313 can be fixedly connected by buckles or screws. The upper cover 311 is provided with a first circulation groove 3113 and a second circulation groove 3114 that are connected, and the heating block 33 is located in the second circulation groove 3114, and the second circulation groove 3114 is the heating area of ​​the heating block 33. A protrusion 3112 is convexly provided at the bottom of the first circulation groove 3113. When the water storage component 2 is installed in the box body 31, the rotary cover 23 and the plugging component can be located in the first circulation groove 3113 and the plugging structure 25 can face the protrusion 3112, and the protrusion 3112 can lift up the plugging structure 25.

[0054] In order to ensure that the liquid can fully flow to the area where the heating block 33 is located, the bottom of the first circulation groove 3113 and the bottom of the second circulation groove 3114 are connected by an inclined surface. In addition, the bottom of the first circulation groove 3113 can also be inclined toward the second circulation groove 3114. In this way, the liquid in the first circulation groove 3113 can smoothly enter the second circulation groove 3114 along the slope.

[0055] The box body 31 is provided with a temperature probe 32 at the bottom of the first circulation groove 3113 or the bottom of the second circulation groove 3114. The temperature probe 32 can detect the water temperature. When the water level in the water tank is in a balanced state, the water level is higher than the temperature probe 32, so that the temperature probe 32 can test the water temperature at any time to facilitate subsequent temperature control operations on the water temperature.

[0056] In one embodiment, the humidifying device also includes an air guide component 4 installed on the box body 31, and the air guide component 4 includes an air guide shell 42. The air guide shell 42 is hollow, and one end of the air guide shell 42 can be mounted outside the heating block 33, and the other end can pass into the jet channel 52 of the jet component 5.

[0057] Specifically, the air guide assembly 4 includes a mounting seat 41 that can be used to connect to the box body 31, and the mounting seat 41 can be connected to the box body 31 by snapping, buckling, or screwing. In this embodiment, a buckling position 3115 is provided on the box body 31 at a position close to the second flow groove 3114, and the mounting seat 41 can be buckled on the buckling position 3115.

[0058] The air guide housing 42 includes a connecting portion 421 and an air outlet portion 422. The connecting portion 421 and the air outlet portion 422 can be welded or integrally formed. In this embodiment, the connecting portion 421 and the air outlet portion 422 are integrally formed. The integrally formed connecting portion 421 and the air outlet portion 422 form a whole, and the whole structure is fixedly connected to the mounting seat 41. For the convenience of manufacturing, the connecting portion 421, the air outlet portion 422 and the mounting seat 41 can also be integrally formed.

[0059] The connection part 421 is preferably a cylindrical tube structure, and the connection part 421 is sleeved outside the heating block 33, and the heating block 33 can be covered inside, and the air outlet 422 is located at the end of the connection part 421. The inner diameter of the air outlet 422 gradually decreases from the end close to the connection part 421 to the end away from the connection part 421, and the end of the air outlet 422 away from the connection part 421 is provided with an opening 4223, and the steam generated by the heating block 33 can enter the interior of the air outlet 422 from the interior of the connection part 421, and then flow out from the opening 4223, and at this time, the opening 4223 can also be regarded as the steam outlet 4221.

[0060] It is worth mentioning that the upper cover 311 is also provided with a sink 3111, and the first circulation groove 3113 and the second circulation groove 3114 are both opened at the bottom of the sink 3111. When the water storage component 2 is connected to the box body 31, the screw-on portion 22, the screw cover 23 and the blocking structure 25 of the water storage component 2 can all extend into the first circulation groove 3113, and the end face of the screw-on portion 22 on the water storage tank 21 is abutted against the bottom of the first circulation groove 3113. Similarly, when the mounting seat 41 is installed on the box body 31, the connecting portion 421 can extend into the second circulation groove 3114, and the bottom end of the mounting seat 41 abuts against the bottom of the second circulation groove 3114.

[0061] In addition, an inner plate 423 can be arranged in the space enclosed by the air outlet portion 422 and the connecting portion 421. The inner plate 423 is arranged around the central axis of the connecting portion 421 to form a cylindrical structure. The top end of the inner plate 423 is fixedly connected to the inner wall of the air outlet portion 422, and part of the space enclosed by this end of the inner plate 423 overlaps with the opening 4223. At this time, the inner plate 423 can divide the space of the air outlet portion 422 close to the opening 4223 into two areas. One is the part enclosed by the top end of the enclosing plate 233 and overlapping with the outlet, which is the steam port 4221. The other is the space enclosed between the inner wall of the air outlet portion 422 and the outer wall of the top end of the inner plate 423. This space can be used as a reflux port 4222 for the reflux of the refluxed liquid. The space enclosed by the bottom end of the inner plate 423 (the end away from the air outlet 422) can cover the heating block 33, so that the heating block 33 can heat and evaporate the liquid in the space enclosed by the inner plate 423, and the evaporated gas can flow out from the steam port 4221 and the opening 4223 in turn, and the condensed liquid can flow back to the box body 31 from the reflux port 4222.

[0062] It should also be noted that a magnet 411 is also provided on the mounting base 41. When the water tank assembly 3 is assembled, the magnet 411 can sense the Hall element of the bed body to transmit an electrical signal, transmitting a signal indicating that the water tank assembly is completed.

[0063] In a specific embodiment, a sealing ring 312 is further provided at the position where the heating block 33 is connected to the box body 31. The sealing ring 312 can increase the sealing of the connection between the heating block 33 and the box body 31, prevent liquid from entering the space with components in the box body 31, and avoid short circuit.

[0064] Specifically, the upper cover 311 of the box body 31 is mainly used to form a space for holding water and evaporating water, and the lower cover 313 is mainly used to install electrical components, mainly including an electric control board for controlling the heating block 33, etc. The space for holding water in the upper cover 311 and the space where the electrical components are located between the lower cover 313 need to be sealed to ensure that the liquid does not enter the lower cover 313. The heating part of the heating block 33 needs to enter the water holding space of the upper cover 311 to heat the liquid. At this time, by setting a sealing ring 312, the sealing ring 312 can seal the connection position between the heating block 33 and the upper cover 311, so that the liquid in the upper cover 311 will not enter the lower cover 313 from the connection position between the heating block 33 and the upper cover 311.

[0065] In addition, one end of the sealing ring 312 is arranged outside the heating block 33 and also outside the inner plate 423, and the end of the sealing ring 312 is located between the connecting portion 421 and the inner plate 423. When the air guide assembly 4 is connected to the box body 31, the end of the connecting portion 421 away from the air outlet portion 422 is arranged close to the bottom of the second circulation groove 3114 to sleeve the sealing ring 312 therein. The position of the sealing ring 312 facing the connecting portion 421 is penetrated by the first guide groove 3121, and the position of the connecting portion 421 corresponding to the first guide groove 3121 is penetrated by the second guide groove 4211. The liquid entering the second circulation groove 3114 can enter the connecting portion 421 through the second guide groove 4211 and the first guide groove 3121 respectively, and then enter the space enclosed by the inner plate 423.

[0066] It is worth mentioning that by setting the first guide groove 3121 and the second guide groove 4211, the speed at which the liquid flows into the area where the heating block 33 is located (i.e., the area surrounded by the inner plate 423) can be controlled. For example, when the first guide groove 3121 and the second guide groove 4211 are arranged opposite to each other, the two guide grooves are completely overlapped. At this time, the channel for liquid flow is the largest and the flow rate is also the largest. When the first guide groove 3121 and the second guide groove 4211 only partially overlap, the speed of liquid circulation is small. The smaller the overlapping area, the smaller the speed of liquid circulation.

[0067] In one embodiment, see Figure 5 and Figure 6 The jet assembly 5 includes a first fixing seat 53 and a second fixing seat 55. The first fixing seat 53 and the second fixing seat 55 are detachably connected, for example, the first fixing seat 53 and the second fixing seat 55 are fixedly connected by screws. The second fixing seat 55 can be fixed to the box body 31 by screws. The jet assembly 5 also includes a nozzle 51 arranged on the first fixing seat 53 and a top block 54 arranged on the second fixing seat 55. Part of the structure of the nozzle 51 can be inserted into the top block 54 to form a whole with the top block 54, and a jet channel 52 is formed between the nozzle 51 and the top block 54.

[0068] In addition, the structure in which the nozzle 51 is inserted into the top block 54 is also sleeved with a compression spring 56, which abuts between the top block 54 and the nozzle 51. When the second fixing seat 55 is fixedly connected to the box body 31, the end of the top block 54 abuts against the opening 4223 of the air outlet 422 under its own gravity and the elastic force of the compression spring 56, so that the jet channel 52 can be connected and sealed with the opening 4223, so that the steam flowing out of the air guide component 4 can enter the jet channel 52. The nozzle 51 can be connected to the device to be humidified, and the nozzle 51 can be connected to the internal humidification space of the device to be humidified through the jet channel 52, and the steam can enter the humidification space from the jet channel 52.
