Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a humidifier with a double sealing structure. Background Art

[0002] A humidifier is a household appliance that increases the humidity of the air. It atomizes water into ultrafine particles and spreads them into the air to increase the humidity of the air, thereby increasing the ambient humidity and effectively improving the air quality. Humidifiers in the prior art usually use a single valve structure to control the water outlet of the humidifier water tank. When the water level is too low, the valve is opened, and when the water level rises to a predetermined value, the valve is closed. However, when the valve mentioned above is damaged and cannot be closed normally, it will cause the water tank to leak all the time. When the water tank is taken out, it is easy to leak water onto the ground. Therefore, some humidifier products are provided with a double valve body structure to solve the problem of water tank leakage. For example, the publication number is CN108253572B and the patent name is a humidifier with a double valve body structure. However, the double valve bodies in the humidifiers with double valve body structures mentioned above include structures such as valve seats, valve cores, water sealing parts and reset parts, which result in the double valve bodies occupying more space, thereby reducing the water tank capacity and water storage tank capacity of the humidifier to a certain extent, causing users to need to add water more times, reducing the user experience.

DETAILED DESCRIPTION

[0028] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art 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.

[0031] Some embodiments of the present utility model disclose a humidifier 100, such as Figure 1-Figure 6 As shown, the sealing structure of the humidifier 100 is more simplified than that in the prior art.

[0032] The humidifier 100 includes a water tank 10 and a water storage tank 20. The water storage chamber is arranged below the water tank 10, and the water in the water tank 10 is for users to add water, which then flows into the water storage chamber of the humidifier 100, and then flows into the atomizing chamber connected to the water storage tank 20, and is atomized by ultrasonic or heating methods, and finally the atomized water is discharged to the outside of the humidifier 100 through the fan to humidify the indoor environment.

[0033] The bottom of the water tank 10 is provided with a water outlet 11 which is arranged through the water tank 10. Water can flow into the water storage chamber through the water outlet.

[0034] The humidifier 100 also includes a double sealing structure 30, which includes a first sealing ring 31 sealed at the water outlet 11, a sealing ball 32 sealed at the top of the first sealing ring 31, a second sealing ring 35 sealed at the bottom of the water tank 10, and a sealing member 33 sealed on the second sealing ring 35, and the sealing member 33 is arranged below the sealing ball.

[0035] According to the principle of the humidifier 100, the humidifier 100 has a double sealing structure 30, one of which is a sealing ball 32 and a first sealing ring 31, and the other is a sealing member 33 and a second sealing ring. There is no need to adopt a double valve body structure as in the prior art, and the sealing structure is simplified to a sealing ball 32, a first sealing ring 31, a sealing member 33 and a second sealing ring 35. The number of sealing workpieces is reduced, and the size of the sealing ball 32 itself is also small. Therefore, the space occupied at the water outlet 11 is reduced, and the capacity of the water tank 10 and the water storage tank 20 can be increased, so that the water in the humidifier 100 is more durable, and users do not need to add water frequently, thereby improving the user experience.

[0036] In order to better understand the sealing function of the double sealing structure 30, an example is given to illustrate:

[0037] When the water level in the water tank 20 is too low, the driving end of the driving structure 300 in the humidifier 100 will drive the seal 33 to move upward in the height direction of the humidifier 100, so that the sealing contact formed between the seal 33 and the second sealing ring 35 will be opened; then, the seal 33 will drive the sealing ball 32 to move upward, so that the sealing contact formed between the sealing ball 32 and the first sealing ring 31 will be opened. In this way, the double sealing structure 30 will be opened, and the water in the water tank 10 can flow from the water outlet 11 into the water tank 20, and then into the atomization chamber.

[0038] When the water level in the water storage tank 20 rises to a predetermined value, the driving end of the driving structure 300 in the humidifier 100 will move downward, so the sealing member 33 will also move downward due to gravity, so that the seal between the sealing member 33 and the second sealing ring 35 will be restored to a seal, and the sealing ball 32 will also move downward due to gravity, so that the seal between the sealing ball 32 and the first sealing ring 31 will be restored to a seal. In this way, the double sealing structure 30 will be sealed again, and the water in the water tank 10 will not leak.

[0039] Optionally, the double sealing structure is detachably connected to the water tank 10. Therefore, the double sealing structure has another advantage in that the user can disassemble the double sealing structure for cleaning to prevent scale from affecting the sealing effect, thereby maintaining a good sealing effect.

[0040] like Figure 3As shown, optionally, there is a gap between the sealing member 33 and the sealing ball 32. In this way, when the sealing member 33 is driven to move upward by the driving end of the driving structure 300, it will not immediately abut against the sealing ball 32, but will first move upward to make up the distance between the gaps before abutting against the sealing ball 32. At this time, the sealing ball 32 can be pushed and move upward. The advantage of such a setting is that it is equivalent to setting a safe distance for delayed operation to avoid the water tank 10 filled with water from accidentally touching the sealing member 33 after being taken out, which directly causes the water tank 10 to leak. Such a setting will be safer and have better sealing performance.

[0041] like Figure 3 As shown, optionally, a first spring 34 is provided between the second sealing ring 35 and the sealing member 33. In this way, when the water level of the water storage tank 20 rises to a predetermined value, the sealing member 33 can automatically reset after there is no external force from the driving end of the driving structure 300.

[0042] like Figure 3 As shown, optionally, the sealing member 33 includes a sealing push rod 331, a sealing ring 332 arranged at the head of the sealing push rod 331, and an abutment portion 333 arranged at the tail of the sealing push rod 331, the sealing ring 332 and the second sealing ring 35 are sealingly connected, the first spring 34 is arranged between the abutment portion 333 and the second sealing ring 35, and the abutment portion 333 is used to act on the driving end of the driving structure 300 in the humidifier 100.

[0043] Optionally, the first spring 34 is sleeved on the circumferential outer side of the sealing push rod 331 .

[0044] like Figure 5 and Figure 6 As shown, optionally, the humidifier 100 also includes a driving structure 300, which includes a float 301, a connecting rod 302 arranged on one side of the float 301, and a driving protrusion 303 arranged at one end of the connecting rod 302, wherein the driving protrusion 303 serves as the driving end of the driving structure 300 and is used for acting on the abutment portion 333 of the seal 33, and the connecting rod 302 is pivotally connected to the pivot seat 21 on the inner bottom wall of the water tank 20. In this way, the driving structure 300 is equivalent to forming a lever, which uses the lever principle to drive the movement of the seal 33, that is, when the water level of the water tank 20 is too low, the float 301 will move downward, and the driving protrusion 303 will move upward, driving the seal 33 to move upward, so that the sealing contact formed between the seal 33 and the second sealing ring 35 will be opened; the seal 33 will drive the sealing ball 32 to move upward, so that the sealing contact formed between the sealing ball 32 and the first sealing ring 31 will be opened, so that the double sealing structure 30 will be opened, and the water in the water tank 10 can flow from the water outlet 11 into the water tank 20, and then into the atomization chamber.

[0045] When the water level of the water tank 20 rises to a predetermined value, the float 301 will move upward, while the driving protrusion 303 will move downward, and will move downward under the resetting action of the elastic member, so that the seal between the sealing member 33 and the second sealing ring 35 will be restored; the sealing ball 32 will move downward due to gravity, so that the seal between the sealing ball 32 and the first sealing ring 31 will be restored, so that the double sealing structure 30 will be sealed again, and the water in the water tank 10 will not leak.

[0046] like Figure 2-4 As shown, optionally, the inner bottom wall of the water tank 10 is provided with a limit cover 40 on the circumferential outer side of the water outlet 11, and the sealing ball 32 is arranged in the limit cover 40. In this way, the sealing ball 32 is prevented from moving too far upward and detaching from the water outlet 11 to cause sealing failure, thereby improving the sealing performance.

[0047] Optionally, a second spring is provided between the limit cover 40 and the top of the sealing ball 32. In this way, when the water level of the water storage tank 20 is too low, the sealing ball 32 moves upward, and the sealing ball 32 acts on the second spring and compresses the second spring; when the water level of the water storage tank 20 rises to a predetermined value, the sealing ball 32 not only moves downward due to gravity, but also the resetting of the second spring also exerts a downward force on the sealing ball 32, so that the sealing ball 32 and the first sealing ring 31 are sealed again.

[0048] like Figure 2-4 As shown, optionally, the inner bottom wall of the water tank 10 is provided with a filter cover 50 on the circumferential outer side of the limit cover 40, and the limit cover 40 is arranged in the filter cover 50. In this way, if there are foreign objects or impurities in the water tank 10, they can be prevented from entering the double sealing structure 30 and causing the sealing performance to be reduced, so as to improve the sealing performance.

[0049] Optionally, the filter cover 50 is configured as a double-layer filter structure, which can improve the filtering performance of the filter cover 50 and further improve the sealing performance.

[0050] like Figure 3 As shown, optionally, the first sealing ring 31 itself has a first sealing hole 311 sealedly connected to the sealing ball 32, the second sealing ring 35 itself is concavely formed with a sealing cavity 351, the bottom of the sealing cavity 351 has a second sealing hole 352 sealedly connected to the sealing ring 332 of the sealing member 33, and the circumferential outer side of the first sealing ring 31 is sealedly connected to the circumferential inner side of the sealing cavity 351 of the second sealing ring 35. In this way, a good sealing effect can be formed between the first sealing ring 31 and the second sealing ring 35, thereby improving the overall sealing performance.

[0051] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
