1. Field of the Invention
The present invention relates to a display, especially to a display with a closed liquid-flowing device being mounted around the display panel.
2. Description of the Prior Arts
As the raise of the income in the modern society, people not only earn money to live, but also the needs for entertainment. The needs to have decorative products are also increased. One of the decorations is a conventional decorative tube. The conventional decorative tube has a tubular body and a pump. The tubular body is filled with liquid. The pump is mounted under the tubular body to pump the liquid and is connected to a power source outside the tubular body. The liquid flows in the tubular body via the pump to perform decorative appearance. However, the conventional decorative tube has numerous disadvantages as following:
1. The tubular body has an opening to allow the pump to be mounted on. To keep the liquid inside the tubular body without leaking out from the opening, the tubular body has a corresponding waterproof structure formed around the opening. Therefore, the manufacturing cost is increased to have the corresponding waterproof structure.
2. Because of the opening of the tubular body, the small objects such as dust and bugs easily get into the tubular body through the opening. The small objects can pollute the liquid inside the tubular body. The polluted liquid can effects the appearance of the conventional decorative tube and may propagate bacteria and vermin.
To overcome the shortcomings, the present invention provides a display with a closed liquid-flowing device to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a display with a closed liquid-flowing device. The display has a sealed body, a display panel, an inactive propeller, an inactive magnet and a driving assembly. The closed body has an inner cavity and liquid. The display panel is mounted around by the closed body. The inactive propeller is mounted rotatably in the inner cavity and has multiple blades to agitate the liquid. The inactive magnet is mounted securely in the inactive propeller. The driving assembly is mounted on the closed body outside the inner cavity and has a power unit, a shaft and an active magnet. The shaft is connected to and is driven by the power unit. The active magnet is attached to the shaft and corresponds to the inactive magnet. With the magnetic force between the active and inactive magnets, the power is transmitted into the closed body without any physical contact. Therefore, the closed body does not require any waterproof structures and the liquid is maintained clean and isolated from the outer environment.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The closed body (10) is tubular shape, hollow and has a rear wall, an inner cavity (12), liquid, decorative particles (13), a guiding partition (14), two channels (15), a protrusion (16) and a mounting bracket (17). The closed body (10) encloses an opening (11) and may have multiple corners. The inner cavity (12) has an outer sidewall. The liquid is filled in the inner cavity (12) and is not limited to but may be water, oil (such as mineral oil), or the mixture and the like. The decorative particles (13) are filled inside the inner cavity (12) and may be paillette, scraps of paper, toys, or the like. The guiding partition (14) is curved, is formed in the inner cavity (12) adjacent to one of the corners of the closed body (10) and has two ends. The channels (15) are formed respectively between the ends of the guiding partition (14) and the outer sidewall of the inner cavity (12). The protrusion (16) is formed on the rear wall of the closed body (10) and protrudes into the inner cavity (12). The mounting bracket (17) is formed on and protrudes out from the rear wall of the closed body (10).

With reference to
The inactive magnet (24) is mounted securely in the inactive propeller (20) and has two magnetic poles both facing to the rear surface of the inactive propeller (20).
The driving assembly (30) is mounted securely on the closed body (10) outside of the inner cavity (12), corresponds to the inactive propeller (20), may be mounted securely on the mounting bracket (17) and has a power unit (31), a shaft (32) and an active magnet (33). The power unit (31) is mounted securely on the closed body (10) outside of the inner cavity (12) and may be mounted securely on the mounting bracket (17). The shaft (32) is connected to and is driven by the power unit (31), aligns with the rotating axis of the inactive propeller (20) and has a distal end. The active magnet (33) is attached securely to the distal end of the shaft (32), corresponds to the inactive magnet (24) and has two magnet poles both facing to the rear surface (21) of the inactive propeller (20).
With further reference to
With further reference to
The monitor as described has numerous advantages. With the magnetic force between the active and inactive magnets (33, 24), the power is transmitted into the closed body (10) without any physical contacts so the closed body (10) does not need any opening. Therefore, the display as described does not have to add any waterproof structures so the manufacturing cost is reduced. Furthermore, the liquid in the inner cavity (12) of the closed body (10) has no chance to be polluted by the outer environment. Thus, the appearance of the liquid is maintained clean.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
