[0042] Existing humidifiers usually require the use of a coupling structure to achieve electrical connection between the host and the water tank.

[0043] In the humidifier of the related art, there is a risk that impurities such as water, dust, etc. in the water tank enter the coupling structure during use, causing leakage and short circuit of the coupling structure, increasing the failure rate of the humidifier and affecting the user's experience and safety of use.

[0044] Based on this, in order to solve the problem that the coupling structure on the existing humidifier has poor waterproof and dustproof effect, see Figure 1 , Figure 2 and Figure 3 The present application provides a coupling structure, which includes an upper coupling component 100, a lower coupling component 200 and a first sealing gasket 300.

[0045] The upper coupling assembly 100 includes an upper coupling body 110 and a plug pin 120 disposed on the upper coupling body 110 .

[0046] The lower coupling assembly 200 includes a lower coupling seat 210 and a plug connector 220 for plugging and mating with the plug pin 120 . The lower coupling seat 210 is formed with a receiving cavity 211 having an opening, and the plug connector 220 is disposed in the receiving cavity 211 .

[0047] The first sealing gasket 300 is sealingly disposed at the opening of the accommodating cavity 211 . The first sealing gasket 300 is provided with an insertion slot 310 communicating with the accommodating cavity 211 . The first sealing gasket 300 is configured to be interference fit with the insertion pin 120 passing through the insertion slot 310 .

[0048] It should be noted that in the upper coupling assembly 100 of the present application, the upper coupling seat body 110 can be but not limited to a shell, a block or other structures, and the pin 120 can be understood as a copper pin, and its shape can be but not limited to a cylindrical copper pin or a square copper pin.

[0049] In the lower coupling assembly 200 of the present application, the lower coupling seat 210 can be, but is not limited to, a shell, a cover or other structures, the connector 220 can be understood as a plug spring, and the pin 120 and the connector 220 are plugged together to form an electrical connection.

[0050] The first sealing gasket 300 of the present application can be a silicone or rubber structure, that is, the first sealing gasket 300 is an elastic structure, which has the ability to elastically deform and restore deformation. The first sealing gasket 300 is sealed at the opening of the accommodating cavity 211 to seal the opening of the accommodating cavity 211. The insertion slot 310 on the first sealing gasket 300 can be, but not limited to, a circular opening, a rectangular opening, etc. When the insertion slot 310 is a rectangular opening, its width is approximately 0.1mm, that is, the diameter of the insertion slot 310 is smaller than the outer diameter of the pin 120. On the basis of allowing the pin 120 to penetrate, it can better isolate impurities such as water droplets and dust from the outside of the accommodating cavity 211.

[0051] It is understandable that when the lower coupling assembly 100 and the lower coupling assembly 200 need to be coupled, the pin 120 on the upper coupling seat body 110 can be passed through the insertion slit 310 on the first sealing gasket 300 into the accommodating cavity 211 to be plugged and matched with the connector 220 in the accommodating cavity 211 to achieve coupling.

[0052] It is not difficult to understand that when the pin 120 passes through the insertion slot 310 on the first sealing gasket 300, with the help of the elasticity of the first sealing gasket 300, the pin 120 will stretch the insertion slot 310 in the radial outward direction, and enter the accommodating cavity 211 of the lower coupling seat body 210 by squeezing and stretching the insertion slot 310. In the process of the pin 120 squeezing and stretching the insertion slot 310, the outer wall of the pin 120 and the inner wall of the insertion slot 310 are in continuous contact and friction. If there are particulate impurities such as water droplets and dust on the outer wall of the pin 120, the water droplets and dust on the pin 120 will be pushed to the outside of the first sealing gasket 300 due to the friction between the outer wall of the pin 120 and the inner wall of the insertion slot 310, thereby reducing the risk of water droplets and dust entering the accommodating cavity 211 and causing leakage and short circuit in the coupling structure.

[0053] In addition, when the pin 120 is stably plugged into the connector 220 in the accommodating cavity 211, the slot 310 on the first sealing gasket 300 recovers its deformation, and an elastic extrusion force radially inward is applied to the pin 120 at the slot 310, so that the slot 310 and the pin 120 are interference-fitted, ensuring that the slot 310 and the pin 120 are in close contact, and also reducing the risk of water droplets, dust and other impurities outside the accommodating cavity 211 entering the accommodating cavity 211 through the slot 310, causing leakage and short circuit in the coupling structure, thereby improving the overall waterproof and dustproof performance of the coupling structure.

[0054] It should also be noted that the coupling structure of the present application can be but is not limited to being configured on household appliances such as humidifiers, soymilk machines, and wall breaking machines, see Figure 6 , Figure 6 The diagram shows a humidifying device, taking the coupling structure configured on the humidifying device as an example, the humidifying device includes a main unit 400, a water tank 500 and the above coupling structure. The lower coupling component 200 is arranged on the main unit 400, the upper coupling component 100 is arranged on the water tank 500, and the lower coupling component 200 and the upper coupling component 100 are plugged and matched.

[0055] It is not difficult to understand that when the humidifying device is in normal use, the water tank 500 is assembled on the host 400 by plugging and matching the pin 120 on the upper coupling component 100 with the connector 220 on the lower coupling component 200, and the host 400 and the water tank 500 are powered on.

[0056] When the user needs to add water to the water tank 500, the water tank 500 can be directly lifted to separate the upper coupling component 100 of the water tank 500 from the lower coupling component 200 of the host 400 as a whole. The water tank 500 is separated from the host 400 and powered off. During the process of the user adding water to the water tank 500, the host 400 can remain dry due to being separated from the water tank 500, thereby preventing water droplets from falling into the host 400 and the lower coupling component 200 of the host 400 during the process of the user adding water to the water tank 500 and causing safety accidents, thereby ensuring the safety of the user adding water to the water tank 500. The coupling structure can separate the host 400 and the water tank 500 on the humidifying device from dry to wet, thereby improving the safety of the humidifying device.

[0057] When the user reassembles the water tank 500 onto the host 400, the outer wall of the pin 120 and the inner wall of the slot 310 are in continuous contact and friction during the process of the pin 120 squeezing and stretching the slot 310. If there are particulate impurities such as water droplets and dust on the outer wall of the pin 120, the water droplets and dust on the pin 120 will be pushed to the outside of the first sealing gasket 300 due to the friction between the outer wall of the pin 120 and the inner wall of the slot 310, thereby reducing the risk of water droplets and dust entering the accommodating cavity 211 and causing leakage and short circuit in the coupling structure, thereby further improving the safety of the humidifier.

[0058] Obviously, the coupling structure of the present application, through the matching arrangement of the upper coupling component 100, the lower coupling component 200 and the first sealing gasket 300, can reduce the risk of water droplets, dust and other impurities outside the accommodating cavity 211 entering the accommodating cavity 211 through the slit 310, causing leakage and short circuit in the coupling structure, and effectively enhance the overall waterproof and dustproof performance of the coupling structure.

[0059] Moreover, when the humidifier device is configured with the coupling structure of the present application, the coupling structure can separate the dry and wet parts of the main unit 400 and the water tank 500 on the humidifier device, thereby improving the safety of the humidifier device. It can also reduce the risk of water droplets, dust and other impurities on the main unit 400 or the water tank 500 entering the accommodating cavity 211 through the slot 310, causing leakage and short circuit in the coupling structure, effectively enhancing the overall waterproof and dustproof performance of the coupling structure, improving the safety of the humidifier device and enhancing the user experience.

[0060] See also Figure 2 , Figure 4 and Figure 5In some embodiments of the present application, the lower coupling assembly 200 further includes a first support 230 disposed in the accommodating cavity 211, the first support 230 divides the accommodating cavity 211 into a plurality of sub-cavities 2111, a first sealing gasket 300 is sandwiched between the first support 230 and the lower coupling seat 210 to seal and cover the openings of all the sub-cavities 2111, and a plurality of insertion slits 310 are opened on the first sealing gasket 300, and the insertion slits 310 are correspondingly connected to the sub-cavities 2111.

[0061] Specifically, the lower coupling assembly 200 is installed on the host 400 of the humidification device, and the first support 230 divides the accommodating chamber 211 into three side-by-side sub-cavities 2111, and each sub-cavity 2111 is provided with a connector 220, and the three connectors 220 can be understood as three wiring terminals. Correspondingly, the first sealing gasket 300 is provided with three side-by-side slots 310, and the slots 310 are correspondingly connected to the sub-cavities 2111. The upper coupling assembly 100 is installed on the water tank 500 of the humidification device, and the upper coupling seat 110 is provided with three side-by-side pins 120, one of the three pins 120 is used to control the power on and off of the water pump inside the water tank 500, and the other two pins 120 are used to control the power on and off of the sterilization lamp inside the water tank 500.

[0062] It is understandable that when the user couples the upper coupling component 100 with the lower coupling component 200, all the pins 120 on the upper coupling seat 110 can be passed through the corresponding insertion slits 310 on the first sealing gasket 300 into the corresponding sub-cavity 2111, so as to be plugged and matched with the connector 220 in the sub-cavity 2111. In this way, the plug-in and matching of multiple groups of pins 120 and connectors 220 can be achieved at one time, thereby improving the overall functionality and compatibility of the coupling structure and enabling the coupling structure to adapt to various types of household appliances.

[0063] Further, see Figure 2 , Figure 3 , Figure 4 and Figure 5 A plurality of assembly openings 212 are provided on the outer wall of the lower coupling seat body 210. The first sealing gasket 300 includes a main body portion 320 and a plurality of embedded portions 330 protruding from the main body portion 320. The main body portion 320 is clamped between the first support 230 and the lower coupling seat body 210. The embedded portions 330 are interference-fitted in the corresponding assembly openings 212.

[0064] Specifically, the first sealing gasket 300 is constructed as a silicone structure, the main body 320 and all the embedded parts 330 of the first sealing gasket 300 are integrally formed, the main body 320 is a rectangular block, and the embedded parts 330 are truncated. Correspondingly, the assembly opening 212 is a circular opening that is interference-fitted with the embedded parts 330.

[0065] It is easy to understand that, in the present application, the main body 320 of the first sealing gasket 300 is sandwiched between the first support 230 and the lower coupling seat body 210, so that the upper and lower end surfaces of the main body 320 are in close contact with the inner wall of the lower coupling seat body 210 and the outer wall of the first support 230 respectively, thereby improving the assembly stability of the first sealing gasket 300, reducing the probability of the first sealing gasket 300 being loose or offset, and ensuring the sealing effect of the first sealing gasket 300 on the accommodating cavity 211. At the same time, by interference-fitting the embedded portion 330 of the first sealing gasket 300 in the corresponding assembly opening 212, the first sealing gasket 300 and the lower coupling seat body 210 can be made to contact more closely, thereby improving the sealing between the first sealing gasket 300 and the lower coupling seat body 210, and further improving the waterproof and dustproof effect of the coupling structure as a whole.

[0066] Further, see Figure 2 , Figure 4 and Figure 5 The first support 230 has a plurality of protrusions 231 at one end close to the first sealing gasket 300 , and the inner wall of the embedded portion 330 is surrounded by a first groove 331 that is plugged and matched with the protrusion 231 .

[0067] Specifically, the protrusion 231 is constructed as a circular expansion at the upper end of the first support 230, and the embedded portion 330 is a hollow truncated cone. When the first sealing gasket 300 is assembled on the lower coupling seat body 210, the embedding portion 330 of the first sealing gasket 300 can be first inserted into the corresponding protrusion 231 of the first support 230, and the main body portion 320 of the first sealing gasket 300 can be flatly attached to the upper surface of the first support 230. In this way, the first sealing gasket 300 is first fixed on the first support 230, and then the first support 230 is installed as a whole in the accommodating cavity 211 of the lower coupling seat body 210 from bottom to top, and the embedding portion 330 of the first sealing gasket 300 is interference fit into the corresponding assembly opening 212 on the outer wall of the lower coupling seat body 210. In this way, the first support 230, the first sealing gasket 300 and the lower coupling seat body 210 are fixed to each other to ensure the assembly stability of the first support 230 and the first sealing gasket 300.

[0068] It can be understood that the coupling structure of the present application can provide positioning and guidance for the assembly of the first support 230 and the first sealing gasket 300 through the plug-in cooperation between the protrusion 231 of the first support 230 and the first groove 331 formed on the inner wall of the embedded portion 330, thereby facilitating the overall assembly of the first support 230 and the first sealing gasket 300 on the lower coupling seat body 210.

[0069] Further, see Figure 2 , Figure 4 and Figure 5A plurality of positioning ridges 232 are also provided on the outer wall of the first support 230, and a plurality of second grooves (not shown in the figure) are provided on the bottom of the first sealing gasket 300, and the positioning ridges 232 are plugged into and matched with the second grooves.

[0070] Specifically, the positioning rib 232 is an annular rib, and correspondingly, the second groove is an annular groove with an opening facing downward. The positioning rib 232 and the second groove are plugged in and matched to make the first sealing gasket 300 contact the first support 230 and the lower coupling seat body 210 more closely, further improving the sealing performance of the coupling structure as a whole.

[0071] See also Figure 3 In some embodiments of the present application, an anti-mistake portion 340 is provided on the first sealing gasket 300, and a mating portion (not shown in the figure) that is alignable and plugged with the anti-mistake portion 340 is provided on the first support 230.

[0072] Specifically, the anti-mistake portion 340 is a rectangular notch opened at the edge of the first sealing gasket 300, and correspondingly, the matching portion is a rectangular protrusion protruding from the outer wall of the first support 230. In this way, through the plug-in cooperation between the anti-mistake portion 340 and the matching portion, the first sealing gasket 300 can be accurately and firmly fixed on the first support 230, further facilitating the assembly of the first sealing gasket 300.

[0073] See also Figure 2 , Figure 4 and Figure 5 In some embodiments of the present application, a second support 240 is provided in the sub-cavity 2111 , and the connector 220 is fixedly mounted on the second support 240 .

[0074] Specifically, the connector 220 is a plug spring, and the second support 240 is a hollow cylindrical structure. The middle part of the second support 240 is provided for inserting the plug spring, and the two sides of the second support 240 are provided for overlapping of two clamping arms of the plug spring. In this way, the connector 220 is stably located in the sub-cavity 2111, so that the pin 120 on the upper coupling seat body 110 can be accurately and stably plugged into the connector 220.

[0075] See also Figure 2 and Figure 5 In some embodiments of the present application, the connector 220 is constructed as an elastic structure, and the connector 220 has an elastic cavity (not shown in the figure) for inserting the pin 120, and the elastic cavity can apply an elastic squeezing force to the pin 120.

[0076] Specifically, the connector 220 is a plug spring, and the maximum elastic squeezing force that the plug spring can apply to the plug pin 120 is 5 Newtons, so that the plug pin 120 is clamped by the moderate squeezing force of the connector 220, which facilitates the pull-out and separation of the plug pin 120 from the connector 220.

[0077] In some embodiments of the present application, see Figure 1 The upper coupling seat 110 includes a control board 111 and a second sealing gasket 112 . The second sealing gasket 112 is disposed on a surface of the control board 111 close to the lower coupling seat 210 . The pin 120 is fixed on the control board 111 and passes through the second sealing gasket 112 .

[0078] Specifically, the second sealing gasket 112 is constructed as a silicone structure. When the upper coupling assembly 100 is coupled with the lower coupling assembly 200, the second sealing gasket 112 is clamped between the lower coupling seat 210 and the control board 111, thereby improving the waterproof sealing between the control board 111 and the lower coupling seat 210, thereby improving the overall safety of the coupling structure. In addition, by directly fixing the plug pin 120 on the control board 111, the plug pin 120 is electrically connected to the corresponding components on the control board 111, which can save the use of wires and reduce the corresponding parts installation cost.

[0079] Also, see Figure 6 The present application also provides a humidifying device, which includes a host 400, a water tank 500 and a coupling structure of any of the above embodiments.

[0080] The lower coupling component 200 is disposed on the main unit 400 , and the upper coupling component 100 is disposed on the water tank 500 . The lower coupling component 200 and the upper coupling component 100 are plug-fitted.

[0081] It is not difficult to understand that when the humidifying device is in normal use, the water tank 500 is assembled on the host 400 by plugging and matching the pin 120 on the upper coupling component 100 with the connector 220 on the lower coupling component 200, and the host 400 and the water tank 500 are powered on.

[0082] When the user needs to add water to the water tank 500, the water tank 500 can be directly lifted to separate the upper coupling component 100 of the water tank 500 from the lower coupling component 200 of the host 400 as a whole. The water tank 500 is separated from the host 400 and powered off. During the process of the user adding water to the water tank 500, the host 400 can remain dry due to being separated from the water tank 500, thereby preventing water droplets from falling into the host 400 and the lower coupling component 200 of the host 400 during the process of the user adding water to the water tank 500 and causing safety accidents, thereby ensuring the safety of the user adding water to the water tank 500. The coupling structure can separate the host 400 and the water tank 500 on the humidifying device from dry to wet, thereby improving the safety of the humidifying device.

[0083] When the user reassembles the water tank 500 onto the host 400, the outer wall of the pin 120 and the inner wall of the slot 310 are in continuous contact and friction during the process of the pin 120 squeezing and stretching the slot 310. If there are particulate impurities such as water droplets and dust on the outer wall of the pin 120, the water droplets and dust on the pin 120 will be pushed to the outside of the first sealing gasket 300 due to the friction between the outer wall of the pin 120 and the inner wall of the slot 310, thereby reducing the risk of water droplets and dust entering the accommodating cavity 211 and causing leakage and short circuit in the coupling structure, thereby further improving the safety of the humidifier.

[0084] It is not difficult to understand that the humidifying device of the present application is equipped with the above-mentioned coupling structure, and therefore also has the same technical effect brought by the above-mentioned coupling structure, that is, the coupling structure can separate the dry and wet parts of the host 400 and the water tank 500 on the humidifying device, thereby improving the safety of the humidifying device. It can also reduce the risk of water droplets, dust and other impurities on the host 400 or the water tank 500 entering the accommodating cavity 211 through the slot 310, causing leakage and short circuit in the coupling structure, effectively enhancing the overall waterproof and dustproof performance of the coupling structure, improving the safety of the humidifying device and enhancing the user experience.

[0085] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
