DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] 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.

[0035] On the one hand, the utility model provides a humidifying device, which can evaporate liquid into water vapor to humidify or keep the environment warm. Figure 1 and Figure 2 The humidifier comprises a shell 1, a water tank assembly 2, an air guide assembly 3 and an air jet assembly 4. The shell 1 is the whole of the humidifier, and the shell 1 can be used as a supporting structure, can also protect the parts, and can also provide an assembly environment for the assembly of the parts.

[0036] The water tank assembly 2 has a water-containing box 21 and a heating block 22. 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 21 as an example for explanation. When the heating block 22 is powered on, it can heat the water in the box 21, thereby promoting water evaporation.

[0037] The air guide component 3 is installed on the box body 21 . The air guide component 3 has a steam port 331 . One end of the air guide component 3 can extend into the position where steam is formed, so that evaporated water vapor can enter the air guide component 3 and flow out through the steam port 331 .

[0038] The jet assembly 4 has a top block 43 and a nozzle 41. One end of the nozzle 41 can be connected to the top block 43, and the other end can be connected to a device that needs humidification. It should be noted here that the device that needs humidification is not limited. In the present application, the humidification device is applied to an incubator for humidifying the incubator, and one end of the nozzle 41 can be connected to the incubator.

[0039] In addition, a jet channel 414 for steam circulation runs through the nozzle 41 and the top block 43. The top block 43 is connected to the box body 21, and one end of the top block 43 can be connected to the steam port 331 through the jet channel 414, so that the steam flowing out of the steam port 331 can enter the device to be humidified from the jet channel 414. It can be seen that the nozzle 41 is not only connected to the incubator, but also needs to extend its end into the incubator. The end extending into the incubator is connected to the internal space of the incubator through the jet channel 414. For example, a jet port 4111 connected to the jet channel 414 can be opened at the end of the nozzle 41, and the steam in the jet channel 414 can enter the incubator through the jet port 4111.

[0040] It is worth mentioning that a first sealing structure 413 is provided at the connection position between the nozzle 41 and the top block 43 , a second sealing structure 4113 is provided at the connection position between the nozzle 41 and the device to be humidified, and a third sealing structure 4312 is provided between the top block 43 and the steam port 331 .

[0041] The humidifying device can be used to humidify equipment such as an incubator that needs humidification. The humidifying device uses the heating block 22 to evaporate the liquid, and then flows out from the steam port 331. The outflowing steam needs to pass through the top block 43 and the nozzle 41 before it can enter the device that needs humidification from the nozzle 41's jet port 4111. By setting the first sealing structure 413 at the connection position between the nozzle 41 and the top block 43, the sealing of the connection between the nozzle 41 and the top block 43 can be increased. The second sealing structure 4113 is set at the connection position between the nozzle 41 and the device that needs humidification. The sealing of the connection between the nozzle 41 and the device that needs humidification can be increased. The third sealing structure 4312 is set between the top block 43 and the steam port 331, which can increase the sealing of the connection between the top block 43 and the steam port 331. By setting the first sealing structure 413, the second sealing structure 4113 and the third sealing structure 4312, the sealing between the structures on the steam flow path can be increased, and steam leakage can be effectively prevented to ensure the humidification and heat preservation effect.

[0042] In one embodiment, please combine Figure 4 and Figure 5 The nozzle 41 includes a mounting portion 412 and an air jet portion 411 connected to the mounting portion 412. The air jet portion 411 is used to be connected to the device to be humidified. The air jet port 4111 is arranged at one end of the air jet portion 411 away from the mounting portion 412. The first sealing structure 413 is connected to one end of the mounting portion 412 away from the air jet portion 411. The first sealing structure 413 is a rubber hose arranged in an annular manner. The first sealing structure 413 can be plugged into one end of the top block 43 away from the steam port 331, and has an interference fit.

[0043] It should be noted that the top block 43 includes a top connection portion 431 and a sleeve connection portion 432 connected together, and the first sealing structure 413 is inserted into the sleeve connection portion 432 to realize the connection between the top block 43 and the nozzle 41. It is worth mentioning that the top block 43 is penetrated with a through hole from the end surface of the top connection portion 431 facing away from the sleeve connection portion 432 to the end surface of the sleeve connection portion 432 facing away from the top connection portion 431, and the assembly portion 412 and the jet portion 411 of the nozzle 41 are also provided with a connecting chamber, the chamber of the jet portion 411 is connected to the jet port 4111, and the chamber of the assembly portion 412 is connected to the first sealing structure 413. In this way, when the first sealing structure 413 is inserted into the sleeve connection portion 432, the through hole of the top block 43 is connected to the first sealing structure 413, and is connected to the chambers in the assembly portion 412 and the jet portion 411 to form a jet channel 414.

[0044] In a specific embodiment, the device to be humidified is provided with a connection hole (not shown in the figure), and the shape and size of the connection hole are preferably adapted to the outer dimensions of the jet part 411, so that the end of the jet part 411 can be plugged and adapted in the connection hole. The end of the jet part 411 used for connecting with the device to be humidified is ringed with two spaced connection ribs 4112, and the connection ribs 4112 are arranged around the circumference of the end of the jet part 411 and protrude from the jet part 411. The second sealing structure 4113 is a sealing ring arranged between the two connection ribs 4112. When the end of the jet part 411 is plugged into the connection hole, the structure of the device to be humidified where the connection hole is located is sandwiched between the two connection ribs 4112 together with the connection hole to prevent the jet part 411 from detaching from the device to be humidified. The inner wall of the connection hole can be interference fit with the second sealing structure 4113, which can not only increase the stability of the connection, but also increase the sealing of the connection.

[0045] In one embodiment, see Figures 1 to 3 The jet assembly 4 further includes a first fixing seat 42 and a second fixing seat 44 which can be connected together, and the second fixing seat 44 can be connected to the box body 21 to connect the entire jet assembly 4 to the box body 21. The second fixing seat 44 is preferably made of a wear-resistant material, such as POM (Polyoxymethylene, polyoxymethylene resin) material.

[0046] Please combine Figure 6 and Figure 7 The first fixing seat 42 is penetrated by a first through hole 421, and the assembly portion 412 of the nozzle 41 can be inserted into the first through hole 421, and the assembly portion 412 can be fixed in the first through hole 421. Specifically, the first fixing seat 42 is provided with a protruding block 423 on the inner wall of the first through hole 421, and the assembly portion 412 is provided with spaced convex ribs 4122. When the assembly portion 412 is inserted into the first through hole 421, the protruding block 423 can be sandwiched between two convex ribs 4122.

[0047] The first through hole 421 penetrates the first fixing seat 42 along a central axis, and the assembly portion 412 is also inserted into the first fixing seat 42 along the axis. The length of the protrusion 423 extends along the central axis of the first through hole 421, and the ribs 4122 are also arranged at intervals along the length direction of the protrusion 423, so that when the assembly portion 412 is inserted into the first through hole 421, the cooperation between the ribs 4122 and the protrusion 423 can prevent the assembly portion 412 from being separated from the first through hole 421.

[0048] It is worth noting that the outer wall of the assembly portion 412 can just abut against the surface of the protrusion 423 facing away from the first fixing seat 42, so that the side wall of the rib 4122 can abut against the side wall of the protrusion 423, and the two ribs 4122 can clamp the protrusion 423. The rib 4122 is preferably made of a material with a certain elasticity, such as rubber or elastic plastic.

[0049] In a specific embodiment, the first fixed seat 42 is preferably provided with a plurality of spaced protrusions 423, and the plurality of protrusions 423 are arranged on the inner wall of the first through hole 421 around the central axis of the first through hole 421. The assembly portion 412 is provided with positioning ribs 4121 between the spaced protrusions 4122, and the gap between two adjacent protrusions 423 forms a positioning groove 422, and the positioning rib 4121 is configured to be plugged and adapted in the positioning groove 422. By providing a plurality of protrusions 423, the gap between two adjacent protrusions 423 and the cooperation of the positioning rib 4121 can prevent the assembly portion 412 and the first fixed seat 42 from rotating relative to each other, so that the assembly portion 412 is neither easy to detach from the first fixed seat 42 nor easy to rotate, so that the connection between the entire nozzle 41 and the first fixed seat 42 is relatively stable.

[0050] It should be noted that the sizes of the positioning grooves 422 between at least two adjacent protrusions 423 are different, that is, the width of the positioning groove 422 between a pair of adjacent protrusions 423 is greater or less than the width of the positioning groove 422 between another pair of adjacent protrusions 423. At this time, the size of the positioning rib 4121 corresponding to the positioning groove 422 needs to be set according to the size of the corresponding positioning groove 422. If the positioning groove 422 is wide, the size of the positioning rib 4121 is larger, and if the positioning groove 422 is narrow, the size of the positioning rib 4121 is smaller.

[0051] Preferably, only two positioning ribs 4121 are provided on the assembly portion 412, and the widths of the two positioning ribs 4121 are different. The width here refers to the size of the positioning rib 4121 in the width direction of the positioning groove 422 when the positioning rib 4121 is inserted into the positioning groove 422. Accordingly, by reasonably arranging the positions of the protrusions 423, two positioning grooves 422 of different sizes can also be formed on the inner wall of the first perforation 421 of the first fixing seat 42, and the positions of the two positioning grooves 422 correspond to the positions of the two positioning ribs 4121, and the sizes also correspond. In this way, the only position where the two positioning ribs 4121 can be inserted is determined, and the position of the assembly portion 412 relative to the first fixing seat 42 is also determined, which means that when the second fixing seat 44 is fixed on the box body 21, the position of the jet outlet 4111 of the nozzle 41 relative to the box body 21 is also fixed, which is conducive to limiting the direction of the jet outlet 4111 in the device to be humidified, and plays a fool-proof role.

[0052] Of course, this fool-proof method of plugging the positioning rib 4121 and the positioning groove 422 can also be replaced by a positioning hole and shaft plug-in method, or other structures that can determine different connection positions according to different connection sizes, which is not limited here.

[0053] In a specific embodiment, the second fixing seat 44 includes a mounting portion 441 and a plug-in portion 442, wherein the mounting portion 441 is used to connect with the box body 21 and the first fixing seat 42. Specifically, the mounting portion 441 is provided with a mounting edge 4412 and a mounting nail 4413, wherein the mounting nail 4413 can be connected to the first fixing seat 42 by screws, and the mounting edge 4412 can be connected to the box body 21 by screws.

[0054] The second fixing seat 44 also has a second through hole 4411 that penetrates both the mounting portion 441 and the plug-in portion 442. As mentioned above, the top block 43 includes a top connection portion 431 and a sleeve connection portion 432, and the sleeve connection portion 432 can be inserted into the second through hole 4411. A positioning opening 4431 is provided at one end of the plug-in portion 442 away from the mounting portion 441, and an assembly rib 4313 that can be inserted into the positioning opening 4431 is protruded from the top connection portion 431 near the position where it is connected to the sleeve connection portion 432. When the top block 43 is plugged into the second fixed seat 44, the top connection part 431 is first plugged from one end of the mounting part 441 toward one end of the plug-in part 442. During the plug-in process, the assembly rib 4313 and the positioning opening 4431 are aligned so that the top connection part 431 can smoothly extend from the end of the plug-in part 442 facing away from the mounting part 441, and the structure between the sleeve part 432 and the plug-in part 442 is set to be able to extend from one end but not extend from the other end.

[0055] Specifically, the diameter of the second through hole 4411 is larger than the radial dimensions of the top connection portion 431 and the sleeve connection portion 432, and a circle of abutment edge 443 is protruded toward the axis of the second through hole 4411 at one end of the plug-in portion 442 away from the mounting portion 441, and the abutment edge 443 is arranged to form an annular space of the same shape as the second through hole 4411, but the size is smaller than the second through hole 4411. The size of the annular space is larger than the radial dimension of the top connection portion 431 and smaller than the radial dimension of the sleeve connection portion 432, so that the shaped end can be extended while the sleeve connection portion 432 cannot extend out of the plug-in portion 442. The positioning port 4431 is opened on the abutment edge 443.

[0056] It should be noted that a compression spring 45 that can be sleeved on the outside of the sleeve portion 432 is provided in the second through hole 4411, and the first fixed seat 42 is also provided with a contact block 424 near the position connected to the second fixed seat 44. A contact ring 4321 is protruded from the sleeve portion 432 near the top connection portion 431, and the two ends of the compression spring 45 can respectively abut on the contact ring 4321 and the abutment block 424.

[0057] After the first fixing seat 42 and the second fixing seat 44 are fixed, the first sealing structure 413 is plugged into the sleeve portion 432, which is equivalent to the first sealing member being also plugged into the plug-in end. A circle of contact ring 4321 is protruded on the peripheral wall of the sleeve portion 432 near the top portion 431, and the two ends of the compression spring 45 are respectively abutted against the contact ring 4321 and the abutment block 424, so that the assembly portion 412 can be pressed against the abutment edge 443 by the elastic action of the compression spring 45. In addition, as long as there is an external force that can overcome the elastic force of the compression spring 45, the assembly portion 412 can be moved along the central axis of the second through hole 4411 in the plug-in portion 442. This arrangement is for the convenience of matching with the air guide component 3.

[0058] For example, in one embodiment, the air guide assembly 3 includes a mounting seat 31 that can be used to connect to the box body 21, and a connecting portion 32 and an air outlet portion 33 that are connected to each other. The mounting seat 31 can be connected to the box body 21 by snapping or buckling, the latter of which is fixedly connected to the box body 21 by screws. In this embodiment, a buckling position 23 is provided on the box body 21, and the mounting seat 31 can be buckled on the buckling position 23.

[0059] The connecting portion 32 and the air outlet portion 33 can be welded or integrally formed. In this embodiment, the connecting portion 32 and the air outlet portion 33 are integrally formed. The integrally formed connecting portion 32 and the air outlet portion 33 form a whole, and the whole structure is fixedly connected to the mounting seat 31. For the convenience of manufacturing, the two are also integrally formed.

[0060] The connecting portion 32 can be in contact with the position where steam is generated in the water tank. The connecting portion 32 is preferably of a cylindrical structure and can cover the heating block 22 inside. The air outlet portion 33 is located at the end of the connecting portion 32. The inner diameter of the air outlet portion 33 gradually decreases from the end close to the connecting portion 32 to the end away from the connecting portion 32. An opening 333 is provided at the end of the air outlet portion 33 away from the connecting portion 32. The steam generated by heating by the heating block 22 can enter the interior of the air outlet portion 33 from the interior of the connecting portion 32, and then flow out from the opening 333. At this time, the opening 333 can also be regarded as a steam outlet 331.

[0061] In addition, an inner plate 34 can be arranged in the space enclosed by the gas outlet 33 and the connecting portion 32, and the inner plate 34 is arranged around the central axis of the connecting portion 32 to form a cylindrical structure, and the top of the inner plate 34 is fixedly connected to the inner wall of the gas outlet 33, and the space enclosed by this end of the inner plate 34 partially overlaps with the opening 333, and the space enclosed by the bottom end of the inner plate 34 (the end away from the gas outlet 33) can cover the heating block 22.
