Detailed Description
The technical solutions of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. In addition, technical features involved in different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.
Some household appliances often include a water storage device, such as a humidifier, a water purifier, a steam iron, an air cooler, etc., and a water tank for storing water is disposed inside the household appliance, so that the appliance consumes the water in the water tank to realize related functions. For example, humidifiers humidify the room environment by ultrasonically atomizing water in a water tank. For these appliances including the water storage device, users are often required to pay attention to the water storage capacity of the water tank, and too low or too high water amount not only causes the related functions to be unavailable, but also causes dry burning or short circuit damage of the equipment, and seriously causes fire.
In the related art, in order to enable a user to observe the liquid level of the water storage device, a viewing hole is often formed in the equipment housing. For example, in the humidifier shown in fig. 1, a long observation hole 10 is formed in the housing, and the observation hole 10 is made of a transparent material, so that a user can observe the liquid level of the internal water tank through the observation hole 10.
However, the appearance of the device is often limited by ID (Industrial Design), the width of the observation hole 10 is narrow, the amount of light entering is small, especially in a low light environment, the liquid level height is difficult to distinguish, the visual indication effect is poor, and the user experience is greatly reduced.
Based on the above defects in the related art, the embodiments of the present disclosure provide a liquid level indicating structure, and a liquid storage device and an electrical apparatus having the liquid level indicating structure.
The embodiment of the disclosure provides a liquid level indicating structure, which can be applied to liquid storage devices such as water tanks, wherein the liquid storage devices comprise a shell, and the liquid level indicating structure is arranged on the side wall of the shell to realize liquid level indication of the liquid storage devices.
Specifically, in some embodiments, the liquid level indicating structure includes a first viewing portion disposed on a sidewall of the housing, the first viewing portion allowing light external to the housing to pass through to the interior. For example, in one example, the first observation portion is formed by integrally molding a transparent material on the housing, so that the liquid level inside the housing can be observed from the outside of the housing through the first observation portion. The length of first observation portion extends in stock solution device's stock solution direction of height, and the rectangular shape that also is first observation portion for setting up along stock solution direction of height to guarantee to instruct the liquid level position of each height of stock solution device.
And a buoy cover is arranged on the inner side wall of the shell at the position corresponding to the first observation part and is detachably connected with the shell. When buoy cover and casing assembly connection, buoy cover and the cooperation of first observation portion form one and hold the chamber, and the intercommunication that the intercommunication held chamber and casing inner chamber is seted up on the buoy cover to the feasible chamber that holds forms the linker with the stock solution device, both liquid levels keep unanimous. The buoy is freely arranged in the accommodating cavity and is suitable for floating above the liquid level under the action of liquid buoyancy, so that the liquid level in the liquid storage device can be known by observing the position of the buoy outside the shell. Meanwhile, in order to ensure that the buoy is always positioned in the accommodating cavity, the size of the buoy is larger than the communication hole.
According to the liquid level indicating structure, the buoy is arranged in the containing cavity formed by the buoy cover and the first observation part, so that the height of the buoy can be observed by the outside of the shell through the first observation part, the liquid level height can be directly observed through the first observation part, the visual effect of liquid level indication is greatly enhanced, a user can easily observe the liquid level height of the liquid storage device, and the user experience is improved.
It is worth mentioning that at least one inventive concept of the disclosed liquid level indicating structure is that: the buoy cover is detachably connected with the shell. The inventor of the present invention found through research that, for devices such as household appliances, the appearance of the devices is limited by ID, so the first observation portion is often set to be in a long strip shape, and thus the corresponding buoy cover is also in a long strip shape, and in order to make the buoy be always accurately located at the position corresponding to the first observation portion, the size difference between the buoy and the buoy cover needs to be set to be small. However, after long-term use, bacteria and algae (also called "green hair") can be attached to the inner walls of the buoy and the buoy cover, so that the buoy is clamped and cannot normally float on the liquid level, the liquid level height cannot be accurately indicated, meanwhile, water quality is affected, peculiar smell is generated, and user experience is reduced.
The inventor of the present disclosure finds the above-mentioned defect, and thus in the liquid level indicating structure of the embodiment of the present disclosure, the detachable connection between the float cover and the housing is provided, so that the user can detach and clean the float and the float cover conveniently, the float is prevented from being interfered, and the liquid level height is accurately indicated.
Fig. 2 and 3 show a specific embodiment of the liquid level indicating structure and the liquid storage device of the present disclosure, in which the liquid storage device is exemplified by a humidifier water tank, and the following detailed description is provided with reference to fig. 2 and 3.
As shown in fig. 2, the liquid storage device includes a housing 100, and a cavity for storing water is formed by a bottom wall and a side wall of the housing 100. The first observation portion 110 is disposed on a sidewall of the casing 100, and the first observation portion 110 allows light outside the casing 100 to penetrate to the inside, that is, the first observation portion 110 is made of a transparent material. In one example, the first observation portion 110 may be formed by opening an observation hole on a sidewall of the housing 100 and then sealing a transparent material in the observation hole. In another example, the first viewing portion 110 may be integrally injection molded with the housing 100 using a transparent material. Those skilled in the art will appreciate that the implementation of the first viewing portion 110 may also be in any other manner, and the present disclosure is not limited thereto.
With continued reference to fig. 2, the first observation portion 110 is an oblong shape, and a length direction thereof extends along a liquid storage height direction of the liquid storage device, that is, the length direction of the first observation portion 110 is arranged along a vertical direction, so that after liquid is added into the liquid storage device, a liquid level inside the liquid storage device can be observed from the outside of the housing 100 through the transparent first observation portion 110.
A float cover 120 is provided on an inner side wall of the housing 100 at a position corresponding to the first observation unit 110, and in the present embodiment, the float cover 120 is detachably connected to the housing 100 by a plug connection structure. Specifically, as shown in fig. 3, an insertion part 111 is fixedly disposed on an inner side wall of the housing 100 at the position of the first observation part 110, and a shape-fitting insertion groove 121 is disposed on the float cover 120. Thus, in the configuration shown in fig. 3, the float cover 120 is inserted into the insertion portion 111 of the housing 100 from top to bottom, and the assembly is completed, and the disassembly is reversed.
After the float cover 120 is assembled with the housing 100, the float cover 120 cooperates with the first observation portion 110 to form a receiving cavity, in which the float 130 is disposed, in this embodiment, the float 130 is a floating ball, and it will be understood by those skilled in the art that the float 130 may have any other structure suitable for implementation, and the disclosure is not limited thereto.
In order to ensure that the receiving chamber communicates with the inner chamber of the housing 100, a communication hole 122 is formed in the float cover 120. As shown in fig. 3, in the present embodiment, the communication hole 122 is an elongated hole extending in the vertical direction. Since the communication hole 122 is a through hole, a communicating structure is formed inside and outside the containing chamber, so that the liquid level in the containing chamber is equal to the liquid level in the inner chamber of the housing 100, thereby accurately indicating the liquid level.
It will be appreciated that, in order to ensure that the float 130 is located inside the accommodating chamber and to prevent the float 130 from falling out through the communication hole 122, the size of the float 130 should be larger than the communication hole 122.
It should be noted that the communication hole 122 is a long hole extending in the vertical direction, so that convection can be formed between the inside and the outside of the accommodating chamber, and as the liquid level in the inner cavity of the housing 100 rises, the air pressure in the accommodating chamber can be discharged from the communication hole 122 at the upper end, thereby ensuring that the accommodating chamber is level with the liquid level of the liquid storage device.
When the liquid level in the liquid storage device changes, the liquid level in the accommodating chamber changes simultaneously, so that the float 130 of the accommodating chamber changes up and down, and a user can visually observe the change of the float 130 through the transparent first observation part 110 outside the housing 100.
In this embodiment, the float 130 is a floating ball. Preferably, to further increase the visual effect of the float 130, the float ball may be set to a more striking color, such as red, yellow, green, etc. In other embodiments, the number of the floating balls is not limited to 1, and other numbers are also possible, which is not limited by the disclosure.
In some embodiments, to facilitate a user to accurately and intuitively know the current amount of the fluid stored in the fluid storage device, a scale may be provided on the transparent first observation portion 110, so as to accurately indicate the current amount of the fluid stored.
It can be understood that the liquid storage device is exemplified by a humidifier water tank, but the liquid storage device and the liquid level indication structure disclosed in the present disclosure are not limited to this example, and may also be any other application scenario suitable for liquid level indication, and meanwhile, the liquid is not limited to water, and any other liquid suitable for implementation may be used.
The liquid level indicating structure and the liquid storage device according to the present embodiment are explained above, and the assembling method and the operation principle are explained below.
The first observation portion 110 is first disposed on the side wall of the housing 100, for example, the transparent first observation portion 110 is formed on the housing 100 by injection molding, and then the float cover 120 is inserted into the insertion portion 111 on the housing 100 by using the insertion connection structure, and the float 130 is freely placed in the accommodating cavity formed by the float cover 120 and the first observation portion 110, so as to complete the assembly.
When liquid is added into the liquid storage device, the liquid level in the accommodating cavity rises along with the rise of the liquid level, and the buoy 130 floats and rises along with the liquid under the action of buoyancy of the liquid. For the user, the height of the float 130, that is, the current liquid level height, can be visually observed from the outside of the housing 100 through the first observation portion 110.
Through the above, in the embodiment, the buoy 130 is arranged in the accommodating cavity formed by the buoy cover 120 and the first observation part 110, so that the height of the buoy 130 can be observed from the outside of the shell 100 through the first observation part 110, the liquid level height can be directly observed through the first observation part, the visual effect of liquid level indication is greatly enhanced, a user can easily observe the liquid level height of the liquid storage device, and the user experience is improved. And, the plug-in connection structure of the float cover 120 and the housing 100 is provided, so that the user can conveniently detach and clean the float and the float cover, the float is prevented from being interfered, and the liquid level is accurately indicated.
On the basis of the above embodiments, the liquid level indicating structure and the liquid storage device of the present disclosure can also have other alternative embodiments.
In an alternative embodiment, the difference from the embodiment of fig. 2 is the structure of the communication hole 122. Therefore, the communicating hole 122 has the functions of enabling the accommodating cavity and the inner cavity of the shell to form a communicating device on one hand, and enabling the inside and the outside of the accommodating cavity to form convection on the other hand, so that the liquid level in the accommodating cavity is always kept level with the inner cavity of the shell when the liquid level rises. Therefore, in the present embodiment, as shown in fig. 4, the communication hole 122 includes two through holes, for example, the first through hole 123 and the second through hole 124 are shown in the drawing, and the first through hole 123 and the second through hole 124 are respectively disposed at the upper end and the lower end of the float cover 120 in the height direction, so that as the liquid level in the liquid storage device increases, the accommodating chamber can keep convection with the outside through the first through hole 123 at the upper end, so that the liquid level in the accommodating chamber is always kept level with the liquid storage device. Of course, those skilled in the art can understand that the communication hole 122 may also include other numbers of through holes, and it is only necessary to ensure that at least two through holes of the through holes are separately disposed at the upper end and the lower end, which is not described herein again.
In another alternative embodiment, the detachable connection manner of the float cover 120 and the housing 100 is not limited to the plug connection structure shown in fig. 2, and may be any other connection structure suitable for implementation, such as a snap connection structure, a screw connection structure, and the like, which can be understood and implemented by those skilled in the art, and the disclosure will not be described herein again.
In another aspect, the present disclosure provides an electrical apparatus, which may include the liquid storage device and the liquid level indicating structure in any of the above embodiments. For example, a humidifier, an air cooler, a water purifier and other household appliances are all internally provided with liquid storage devices such as a water tank and the like.

The electrical equipment of the embodiment of the present disclosure includes a body, the body refers to a main structure of the humidifier, which may include the housing 200, the water storage device and the electrical part which are disposed inside the housing 200, and the like.
As shown in fig. 5, the water storage device is disposed inside the housing 200, the second observation portion 210 is disposed at a position of the housing 200 corresponding to the first observation portion 110 of the water storage device, and the second observation portion 210 functions similarly to the first observation portion 110, so that a user can observe the first observation portion 110 inside from the outside of the housing 200 through the second observation portion 210, and further know the liquid level inside the water storage device through the float 130.
It should be noted that, since the casing 200 is an external casing structure of the device, it is not necessary to contact with the liquid in the liquid storage device, and therefore the second observation portion 210 may be a through hole opened on the casing 200. Of course, it can be understood by those skilled in the art that, in order to improve the sealing performance and appearance integrity of the device, the second observation portion 210 may also be fixed to the housing 200 by using a transparent material, which can be implemented by referring to the aforementioned embodiment of the first observation portion 110, and will not be described herein again. For example, in the embodiment shown in fig. 5, the second observation portion 210 is fixed and assembled to the housing 200 by using a transparent material.
In some embodiments, in order to allow a user to accurately and intuitively know the current water storage amount of the liquid storage device, a scale may be provided on the first observation portion 110 or the second observation portion 210, so as to accurately indicate the current water storage amount.
The assembling method of the electrical equipment of the present embodiment can be implemented by referring to the foregoing description by those skilled in the art, and details thereof are not described again. After the water is added to the liquid storage device, the height of the water level rises, and the float 130 in the liquid level indicating structure rises, so that the user can visually observe the height of the float 130, i.e., the current water level, through the second observation part 210 and the first observation part 110.
Therefore, in the embodiment, the height of the buoy 130 is observed through the second observing part 210 and the first observing part 110, and compared with the height of the liquid level, the visual effect of liquid level indication is greatly enhanced, so that a user can easily observe the liquid level of the liquid storage device, and the user experience is improved. And the liquid level indication structure is detachably connected, so that a user can conveniently detach and clean the buoy and the buoy cover, the buoy is prevented from being interfered, and the liquid level height is accurately indicated.
It should be understood that the above embodiments are only examples for clearly illustrating the present invention, and are not intended to limit the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the present disclosure may be made without departing from the scope of the present disclosure.
