Description

Technical Field

[0001] The present application relates to the technical field of air humidifiers, and in particular to a water tank and a humidifier. Background Art

[0002] A humidifier is an electrical appliance that increases the humidity of an environment. Conventional humidifiers often include a water tank and an atomizing device. The water tank is provided with a water discharge mechanism, which is used to connect the atomizing device and allow the water in the water tank to flow to the atomizing device. The existing water discharge mechanism includes a water outlet and a sealing device. The sealing device is often a sealing silicone, which is sealed and connected to the water outlet and blocks the water outlet. The sealing silicone achieves a sealed connection with the water outlet under the joint action of water pressure or a connected spring drive component. However, due to the structure of the sealing silicone itself, it is prone to slight deformation when it is subjected to uneven force, making the sealing surface connected to the water outlet uneven, thereby causing the seal to fail and causing the water tank to leak.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0034] See also Figures 1 to 6 , the embodiment of the present application provides a water tank 100 and a humidifier 200. The water tank 100 is applied to the humidifier 200, and the water tank 100 includes a box body 10, a cover body 30 and a sealing assembly 40. The sealing assembly 40 plays a sealing role to ensure that the water tank 100 inside the humidifier 200 is isolated from the external environment. The cover body 30 has a first mounting platform 31, and the first mounting platform 31 is provided with a drainage channel 311. The sealing assembly 40 includes a connector 41 and a sealing member 42, and the sealing member 42 is also provided with a deformation sealing portion 422. In this embodiment, the water tank 100 is used to store liquid water and prevent dust and impurities from contaminating the liquid water. The drainage channel 311 is used to enable the water in the water tank 100 to flow into the atomization generating device of the humidifier 200 to ensure the normal use of the humidifier 200. The deformation sealing portion 422 is used to improve the sealing performance by interference fit with the drainage channel 311.

[0035] In the present embodiment, the humidifier 200 is used to humidify the air. The humidifier 200 may include a base 210, which is used to connect the water tank 100 and to support the use place of the humidifier 200. The use place may be a desktop, a ground or other supporting plane. The base 210 may be divided into a stacked atomization generation area (not shown in the figure) and an installation area (not shown in the figure), and the atomization generation area is used to generate water mist and transport water mist. The installation area is used to install a circuit board and a wire to achieve electrical connection between the humidifier 200 and an external circuit. The base 210 is suitable for matching the outer contour and size of the water tank 100. A stabilizing member (not shown in the figure) may be provided in the installation area or bottom of the base 210, and the stabilizing member may be a counterweight. The counterweight may add weight to the base 210 to prevent the humidifier 200 from tipping over during use.

[0036] See also Figures 3 to 5 The base 210 may also include a water discharge device 220 and an atomization generating device (not shown in the figure), and the cover body 30 may also include an atomization chamber 32, which is extended toward one side of the base 210 and covers the atomization generating device. Specifically, the water tank 100 is installed on the base 210 after adding water, and the water discharge device 220 enables the water in the water tank 100 to enter the atomization generating device. As an example, the water discharge device 220 includes a floating plate 221 and a hinge seat 222, and the floating plate 221 may include a rotating arm (not shown in the figure), and a floating body portion 2212 and a pressing portion 2213 respectively arranged at both ends of the rotating arm, the rotating arm is rotatably arranged on the hinge seat 222, and the pressing portion 2213 can be abutted against one end of the connecting member 41.

[0037] The housing 10 can be located above the atomizing chamber 32 and connect the drainage channel 311 and the atomizing chamber 32, and the water in the water tank 100 can be directly discharged into the atomizing chamber 32. The mass of the floating body 2212 is greater than the mass of the pressing part 2213. When the water level in the atomizing chamber 32 is lower than the predetermined water level, the floating body 2212 is subjected to a smaller buoyancy, and the floating body 2212 sinks and causes the pressing part 2213 to tilt up. After the pressing part 2213 tilts up, it abuts against the connecting piece 41 of the water tank 100 and lifts up the sealing piece 42, so that the sealing piece 42 is released from the sealing contact with the first mounting platform 31, so that the water in the water tank 100 flows into the atomizing chamber 32 through the drainage channel 311. In the atomizing chamber 32, this process can continuously supply water to the atomizing chamber 32; when the water level in the atomizing chamber 32 rises to a predetermined water level, the buoyancy of the float 2212 is greater than its own gravity, the float 2212 floats up and causes the pressing part 2213 to fall back, so that the connecting member 41 and the sealing member 42 also fall back synchronously under the action of pressure, and the sealing member 42 falls back to the first mounting platform 31 and contacts with the first mounting platform 31 to maintain a sealed state, and at this time, the water supply to the atomizing chamber 32 is stopped. It should be noted that the pressure can be any one of the water pressure or the gravity of the sealing assembly 40 itself, or the thrust of other devices, such as the thrust of a spring.

[0038] See also Figure 4 and Figure 5 In the embodiment of the present application, the water tank 100 includes a box body 10, a cover body 30 and a sealing assembly 40. The box body 10 is provided with a receiving chamber 11 and an opening 12, and the opening 12 is located at one end of the box body 10 and communicates with the receiving chamber 11. When the water tank 100 is normally installed, the opening 12 is located at the lower end of the box body 10 in the gravity direction. The cover body 30 is arranged at the opening 12 and covers the receiving chamber 11. The cover body 30 includes a first mounting platform 31, and the first mounting platform 31 is provided with a drainage channel 311. The sealing assembly 40 is movably arranged on the first mounting platform 31, and the sealing assembly 40 includes a connecting member 41 and a sealing member 42. The sealing member 42 is arranged at one end of the connecting member 41 facing the receiving chamber 11, and the connecting member 41 is penetrated in the drainage channel 311. The sealing member 42 has a deformable sealing portion 422. Under the action of external pressure, the deformable sealing portion 422 and the first mounting platform 31 are squeezed and deformed to seal the drainage channel 311. In the embodiment of the present application, the cover 30 is connected to the box body 10, which is convenient for disassembly and installation of the internal components of the box body 10. The water tank 100 includes a sealing assembly 40, which is arranged on the first mounting platform 31. Under external pressure, the sealing member 42 of the sealing assembly 40 can be squeezed on the first mounting platform 31 and cover the drainage channel 311, so as to achieve the sealing and blocking of the sealing member 42 and the drainage channel 311, thereby improving the service life of the humidifier 100. Furthermore, the sealing member 42 also includes a deformation sealing portion 422, which can be squeezed and deformed with the wall of the first mounting platform 31 and seal the drainage channel 311, thereby further improving the sealing performance between the sealing assembly 40 and the drainage channel 311.

[0039] Next, each component of the water tank 100 and the specific structure of each component will be introduced one by one.

[0040] See also Figure 4In this embodiment, the housing chamber 11 of the housing 10 is used to accommodate liquid water and parts, and protects the liquid water and parts. The parts can be a mist guide pipe 13, which connects the atomization chamber 32 and the outside world, so that the water mist can be diffused to the outside world through the mist guide pipe 13 to humidify the air. The parts can also be a softening device (not shown in the figure) or a filtering device (not shown in the figure), which is used to pre-soften and filter the liquid water to provide good water quality conditions for the subsequent atomization process. The housing 10 can also be provided with a top cover (not shown in the figure) or a water inlet 14, which is connected to the housing chamber 11 for easy water replenishment. In order to improve the portability of the humidifier 200, the material of the housing 10 can be ABS plastic, PC plastic or other hard plastic. This can not only reduce the weight of the housing 10 to achieve lightweight and easy disassembly and installation, but also enable the housing 10 to have a certain stability, thereby effectively protecting the devices inside the housing 10. On the other hand, plastic material has the characteristics of low cost, good plasticity, easy processing, and not easy to break, which can reduce the production cost of the humidifier 100. It should be noted that the material of the box 10 can also be other metal materials such as aluminum, stainless steel, copper, etc., and this embodiment does not limit this.

[0041] See also Figures 3 to 6 In this embodiment, the cover 30 is disposed between the box 10 and the base 210, and covers the opening 12 of the box 10. The cover 30 includes a cover body 301 and a first mounting platform 31. The cover body 301 is connected to the first mounting platform 31. The cover body 301 is used to partially install the atomizing chamber 32, the mist guide pipe 13 or other devices. The first mounting platform 31 is used to install the sealing assembly 40. The first mounting platform 31 is provided with a drainage channel 311. The drainage channel 311 runs through the cover 30 and connects the water tank 100 and the base 210, so that the water in the water tank 100 can enter the atomizing chamber 32 through the drainage channel 311. As an example, the drainage channel 311 includes a first drainage section 3111 and a second drainage section 3112, and the second drainage section 3112 is arranged between the accommodating cavity 11 and the first drainage section 3111, and the inner diameter length of the first drainage section 3111 is smaller than the inner diameter length of the second drainage section 3112, so that the sealing assembly 40 can be clamped between the second drainage section 3112 and the first drainage section 3111 to achieve sealing with the drainage channel 311.

[0042] The water tank 100 may also include a filter 15, which is arranged in the accommodating chamber 11 and is used to intercept impurities in the water. Specifically, the filter 15 is arranged on the inner wall surface of the cover 30 and is covered with a sealing assembly 40 and a drainage channel 311. The filter 15 is also provided with a plurality of microporous structures (not shown in the figure), which are used to intercept fine particle impurities in the water, so that the water is further purified and the turbidity of the water is reduced. At the same time, organic matter and bacteria in the water are removed in large quantities as the turbidity is reduced, and good water quality conditions are provided for the subsequent atomization process. In addition, the filter 15 also plays a role in buffering water pressure, which can reduce the impact of the water flow at the first mounting platform 31 and improve the drainage stability. In other embodiments, the number of filter screens 15 can be a multi-layer mesh structure, and the filter apertures of different filter screens 15 can be different, so as to filter impurities in a targeted manner and improve the filtering effect.

[0043] See also Figure 5 and Figure 6 In this embodiment, the sealing assembly 40 includes a connector 41 and a sealing member 42. The sealing member 42 is at least partially disposed in the drainage channel 311. The connector 40 can drive the sealing member 42 to move in the drainage channel 311, so that the sealing assembly 40 can seal the drainage channel 311. Specifically, the connector 41 serves as a transmission member. One end of the connector 41 can be connected to the water discharge device 220. When the external water pressure and the buoyancy of the water discharge device 220 are small, one end of the water discharge device 220 sinks, thereby the connector 41 and the sealing member 42 sink. When the sealing member 42 sinks to a certain position, it can be pressed against the first mounting platform 31 and seal the drainage channel 311. As an example, water in the water tank 100 enters the base 210 through the drainage channel 311. When the water level in the base 210 rises to a preset water level, the floating body 2212 of the floating plate 221 tilts up and the pressing part 2213 falls back, so that the connecting member 41 drives the sealing member 42 to be pressed against the first mounting platform 31, thereby achieving a sealed blockage between the sealing assembly 40 and the drainage channel 311. When the water level in the base 210 drops, the buoyancy of the floating body 2212 is less than its own weight, and the floating body 2212 sinks, so that the pressing part 2213 tilts up and generates an upward thrust. At this time, the connecting member 41 is subjected to an upward thrust and drives the sealing member 42 to separate from the first mounting platform 31, thereby forming a drainage channel 311 and replenishing water to the base 210.

[0044] The sealing assembly 40 may further include an elastic member 43, which is elastically supported between the cover body 30 and the connecting member 41. The elastic member 43 may be a spring, one end of which is supported against the sealing member 42, and the other end of which is supported against the connecting member 41. Under the action of external pressure, the elastic member 43 is squeezed and generates a downward elastic force, so that the connecting member 41 moves away from the direction of the accommodating chamber 11, so that the sealing member 42 is pressed against the first mounting platform 31 and blocks the drainage channel 311. The elastic member 43 may also be a coil spring, a spring sheet, an elastic sleeve, etc., which is not limited in this embodiment. It should be noted that the external pressure may be water pressure or the elastic force of the elastic member 43 itself, or the combined effect of water pressure and elastic force.

[0045] In this embodiment, the cover body 30 is further provided with a second mounting platform 33, which is used to limit the movement path of the sealing assembly 40 and can also be used to install the elastic member 43. The second mounting platform 33 is arranged in the drainage channel 311 and is fixedly connected to the first mounting platform 31. The second mounting platform 33 has a through-hole structure 331, and the axial direction of the through-hole structure 331 is coaxially arranged with the axial direction of the drainage channel 311. The connecting member 41 of the sealing assembly 40 and the elastic member 43 are penetrated through the through-hole structure 331 of the second mounting platform 33, and one end of the elastic member 43 elastically abuts against the second mounting platform 33, and the other end abuts against the connecting member 41. Under the action of external pressure, the sealing assembly 40 can move along the axial direction of the second mounting platform 33. Specifically, the connecting member 41 has a connecting end 411 and an abutting end 412 that are separated from each other, and the connecting end 411 is used to sleeve the sealing member 42, and the sealing member 42 is arranged outside the second mounting platform 33 and is arranged toward the side of the accommodating chamber 11 of the water tank 100. The abutting end 412 is used to abut against the pressing portion 2213. The size of the abutting end 412 is larger than the inner diameter of the second mounting platform 33, so that the abutting portion can abut against the wall of the second mounting platform 33, thereby preventing the sealing assembly 40 from completely extending into the water tank 100. At the same time, the size of the abutting end 412 is smaller than the inner diameter of the first mounting platform 31, which is convenient for drainage.

[0046] By providing the second mounting platform 33, on the one hand, the movement range of the sealing assembly 40 can be limited to prevent the sealing assembly 40 from being completely separated from the first mounting platform 31; on the other hand, the movement direction of the connecting member 41 and the elastic member 43 can be limited, so that the connecting member 41 and the elastic member 43 can move along a preset trajectory, thereby avoiding shaking; in addition, the position of the elastic member 43 can also be limited, thereby reducing the risk of twisting and deformation of the elastic member 43 and ensuring that the elastic member 43 can be used normally.

[0047] See also Figure 6 and Figure 7In this embodiment, the sealing member 42 includes a sealing silicone body 421 and a deformable sealing portion 422, and the deformable sealing portion 422 is connected to the sealing silicone body 421 and protrudes relative to the sealing silicone body 421. Under the action of external pressure, the sealing silicone body 421 can be embedded in the drainage channel 311, so that the deformable sealing portion 422 and the inner wall of the drainage channel 311 are squeezed against each other. In some embodiments, the second drainage section 3112 and the first drainage section 3111 of the drainage channel 311 have different inner diameters, and a step 3113 is protruded on the cover body 30 between the two. The sealing silicone body 421 is the main part of the sealing member 42, which is superimposed on the step 3113. Since the sealing silicone body 421 is a silicone or rubber part, it has a certain deformation ability and can be in close contact with the step 3113, so the sealing effect is better.

[0048] In this embodiment, the deformable sealing part 422 is squeezed with the drainage channel 311 under the action of external force, which can improve the sealing performance between the sealing component 40 and the drainage channel 311. The external force can be the pressure of water. The water in the water tank 100 enters the atomization generating device through the water discharge device 220. When the buoyancy is greater than the self-weight of the floating body part 2212 of the floating plate 221, the floating body part 2212 floats up and the pressing part 2213 sinks. The connecting member 41 loses the support of the pressing part 2213 and moves downward under its own gravity or external water pressure, so that the sealing member 42 connected to the connecting member 41 also moves downward. The external force can also be the elastic force of the elastic member 43. The elastic member 43 is squeezed and generates a downward elastic force. The elastic force acts on the sealing member 42 and drives the sealing member 42 to move downward, so that the deformable sealing part 422 squeezes and seals the drainage channel 311. The external force can also be a combination of water pressure and spring elastic force, which is not limited in this embodiment. Furthermore, the inner wall surface of the deformable sealing portion 422 and the drainage channel 311 is an interference fit, which can further improve the sealing performance between the sealing assembly 40 and the drainage channel 311. As an example, the interference fit between the deformable sealing portion 422 and the drainage channel 311 ranges from 0.1mm to 0.15mm (including the end points). For example, the interference fit between the deformable sealing portion 422 and the drainage channel 311 can be 0.1mm, 0.11mm, 0.12mm, 0.15mm, etc. It should be noted that the interference fit between the deformable sealing portion 422 and the drainage channel 311 can also be other values, which can be set according to actual application requirements, so as to improve the sealing between the deformable sealing portion 422 and the drainage channel 311, which is not limited in this embodiment.

[0049] See also Figure 7In this embodiment, the deformable sealing portion 422 can be located at different positions of the sealing silicone body 421, thereby improving the sealing performance of different parts of the sealing assembly 40 and the drainage channel 311. As an embodiment, the deformable sealing portion 422 may include a first matching portion 423, and the first matching portion 423 surrounds the outer periphery of the sealing silicone body 421. When the sealing silicone body 421 is accommodated in the first drainage section 3111, the first matching portion 423 abuts against the inner wall surface of the first drainage section 3111, thereby further improving the sealing performance between the sealing assembly 40 and the first drainage section 3111. Specifically, the first matching portion 423 has a first end 4231 and a second end 4232, and the first end 4231 and the second end 4232 are opposite to each other. The first end 4231 is connected to the side of the sealing silicone body 421 facing the inner wall surface of the first drainage section 3111, and the second end 4232 extends toward the accommodating cavity 11. The radial dimension of the second end 4232 of the first matching portion 423 can be smaller than the radial dimension of the first end 4231, so that the first matching portion 423 is an inclined protruding portion, and the protruding direction is toward the direction where the accommodating cavity 11 is located, so that the first matching portion 423 of the sealing silicone body 421 is in a trumpet shape open toward the accommodating cavity 11. The provision of the inclined first matching portion 423 can further improve the sealing performance between the sealing assembly 40 and the first drainage section 3111, and the inclined first matching portion 423 can improve the stability during interference fit.

[0050] As another example, the deformable sealing portion 422 may also include a second matching portion 424, which is disposed around the side of the sealing silicone body 421 facing the step 3113. When the sealing silicone body 421 is superimposed on the step 3113, the second matching portion 424 is covered on the step 3113, thereby further improving the sealing between the sealing assembly 40 and the second drainage section 3112. Specifically, the second matching portion 424 has a third end 4241 and a fourth end 4242, and the third end 4241 and the fourth end 4242 are opposite to each other. The third end 4241 is connected to the side of the sealing silicone body 421 facing the step 3113, and the fourth end 4242 extends toward the side of the first drainage section 3111. The radial dimension of the fourth end 4242 of the second matching portion 424 can be smaller than the radial dimension of the third end 4241, so that the second matching portion 424 is an inclined protruding portion, and the protruding direction is toward the direction where the first drainage section 3111 is located, so that the second matching portion 424 of the sealing silicone body 421 is in a trumpet shape away from the closing of the accommodating cavity 11. The provision of the inclined second matching portion 424 can further improve the sealing performance between the sealing assembly 40 and the second drainage section 3112, and the inclined second matching portion 424 can improve the stability during interference fit.

[0051] It should be noted that the number of first matching parts 423 and the number of second matching parts 424 can be multiple, and adjacent matching parts are spaced apart from each other, and adjacent second matching parts 424 are spaced apart from each other, so as to further improve the sealing performance between the sealing assembly 40 and the drainage channel 311. This embodiment does not limit the number of the first matching parts 423 and the second matching parts 424 and the specific locations of their settings.

[0052] See also Figures 6 to 8 , since the sealing silicone body 421 is deformable, in order to prevent the sealing silicone body 421 from being prone to surface unevenness, shaking, deformation and warping during movement and extrusion, the sealing component 40 may also include a support member 44, the rigidity of which is greater than the rigidity of the sealing silicone body 421. The support member 44 may be a silicone member, a rubber member, a plastic member, etc., and is nested and connected with the sealing silicone body 421. Specifically, the nested connection may be fixed together by hot pressing or gluing. Or the support member 44 and the sealing silicone body 421 may be directly connected by insert injection molding or double injection molding during preparation or by other fastening connectors on the premise of meeting the waterproof and strength requirements. For example, a connection groove (not shown in the figure) and a connection convex portion (not shown in the figure) are respectively provided on the sealing silicone body 421 and the support member 44, and the connection convex portion protrudes from the connection groove to achieve connection and fixation. The connection method between the sealing silicone body 421 and the support member 44 is not specifically limited in this embodiment.

[0053] Please refer again Figure 7 , the support member 44 specifically improves the overall strength of the sealing assembly 40 by supporting the sealing silicone body 421. In this embodiment, the support member 44 includes a first support portion 441, and the sealing silicone body 421 includes a first sealing portion 4211, and the first support portion 441 is embedded in the first sealing portion 4211. Specifically, under the action of external force, when the sealing assembly 40 presses the sealing drainage channel 311, the first sealing portion 4211 is located in the first drainage section 3111, and the first matching portion 423 is located on the side of the inner wall surface of the first sealing portion 4211 facing the first drainage section 3111. The first support portion 441 and the inner wall surface of the first drainage section 3111 jointly clamp the first matching portion 423 and the first sealing portion 4211, thereby reducing the deformation and warping of the sealing silicone body 421 during movement. In addition, the sealing performance between the sealing assembly 40 and the drainage channel 311 can be further improved. It should be noted that when the sealing assembly 40 is in a state of not compressing the drainage channel 311 , the first sealing portion 4211 may be located in the second drainage section 3112 , or part of the structure of the first sealing portion 4211 is located in the first drainage section 3111 , and part of the structure is located in the second drainage section 3112 .

[0054] In other embodiments, the support member 44 further includes a second support portion 442, and the sealing silicone body 421 further includes a second sealing portion 4212, and the second support portion 442 is embedded in the second sealing portion 4212. Specifically, the sealing silicone body 421 is superimposed on the step 3113 of the second drainage section 3112, and the second matching portion 424 is located on the side of the second sealing portion 4212 facing the step 3113. The second support portion 442 is partially superimposed on the side of the second sealing portion 4212 away from the step 3113, so that the second matching portion 424 and the second sealing portion 4212 are clamped between the step 3113 and the second support portion 442, thereby further reducing the phenomenon of deformation and warping of the sealing silicone body 421 during movement. In addition, the sealing performance between the sealing assembly 40 and the drainage channel 311 is further improved.

[0055] In other embodiments, the sealing silicone body 421 may further include a limiting flange 4213. The limiting flange 4213 is superimposed on the side of the second support portion 442 away from the step 3113, so as to achieve the compression of the second support portion 442 to further reduce the deformation and warping of the sealing silicone body 421 during the movement, and can improve the stability of the sealing assembly 40 during the movement process, thereby ensuring the reliability of the humidifier 100.

Further, the sealing component 42 also includes a deformation sealing part 422, and the deformation sealing part 422 can be squeezed and deformed with the wall of the first mounting platform 31 and seal the drainage channel 311, so as to further improve the sealing performance between the sealing component 40 and the drainage channel 311.
