BACKGROUND
[0002] It can be known from the technology of Chinese Taiwan patent TW202036520 A (air conditioner) and the technology of Japanese Patent Publication No. 2010-14288 that an air conditioner can achieve the effect of cleaning the indoor heat exchanger of the air conditioner by the patent technology of refrigeration cleaning. It can provide the cleaning function of cleaning the dirt such as dust, oil, bacteria and foreign particles adhered to the indoor heat exchanger of the air conditioner through freezing and thawing without external cleaning water flow or additional cleaning agent and physical contact mechanical brushing. Therefore, the waterproof head-mounted display suitable for the utility model can achieve the function of cleaning the waterproof head-mounted display through similar water freezing and thawing operation mode after operation. SUMMARY
[0003] The head-mounted display (HMD) is a kind of goggle type display device with image components. The user can realize the effect of virtual reality (VR) visually through the image components built-in the head-mounted display, so the head-mounted display is also a kind of method that can provide VR effect for user experience at present.
[0004] The utility model can cover the head-mounted display of the foregoing prior art with a layer of transparent waterproof film, so that the head-mounted display can be processed into the waterproof head-mounted display suitable for the utility model and having water vapor and dirt isolation function. The isolation function provided by the transparent waterproof film can enable the waterproof head-mounted display to operate normally in an environment with water vapor and dirt, and the waterproof head-mounted display can be safely used and electronic and electrical operation failure can be avoided. The transparent waterproof film is fixed to the surface of the waterproof head-mounted display, and the planar image component inside the waterproof head-mounted display can output images to the direction of the user's eyes. The images can be output to the user's eyes through the transparent waterproof film, so that the waterproof head-mounted display can maintain normal operation function.
[0005] The transparent waterproof film can be made of a conventional transparent heat-shrinkable polymer material. After the transparent waterproof film is wrapped on the waterproof head-mounted display, the transparent waterproof film wrapped on the surface of the waterproof head-mounted display can be heated by a hot air gun or other heating device. The transparent waterproof film can shrink and tightly adhere to the surface of the waterproof head-mounted display due to heating, so that the waterproof head-mounted display can achieve the required waterproof protection function.
[0006] Because the volume of water expands by 9% when it freezes, dirt on the surface of an object with a water film can be separated from the surface of the object through the physical phenomenon of different expansion and contraction volume changes of different substances, so that the object can achieve the effect of surface cleaning by water. Referring to the Hitachi (Hitachi) variable frequency air conditioner (NT type cooling and heating, NJF type cooling and heating) sold in the 2022 Taiwan household appliance market, it can be known that the technology used in this series of products refers to the technology described in the prior art of this specification, and the patent technology of Japanese Patent Application No. 2010-14288 for freezing cleaning. The machine type provides a cleaning function of 2.0+ for freezing cleaning, which can clean the heat exchanger in the air conditioner through freezing and thawing actions to achieve the effect of cleaning the heat exchanger in the air conditioner. Without the need for external cleaning water flow or additional cleaning agent and physical contact mechanical brushing, the operation of the air conditioner function can provide the function of cleaning the dirt such as dust, oil, bacteria and foreign particles adhered to the heat exchanger in the air conditioner. Moreover, it can accelerate the drying of the machine body by running the hot air, thereby providing complete air conditioner cleaning and cleaning functions.
[0007] The freezing and heating box of the present application can refer to the water freezing and water thawing water cleaning technology described above, so that the sprayed water film on the surface of the waterproof head-mounted display of the present application can freeze and melt, and the subsequent cleaning function can be achieved. Moreover, the position of the water film can include all positions of the waterproof head-mounted display that are easy to adhere to dirt during operation of the waterproof head-mounted display.
[0008] The present application is an environmentally friendly cleaning device combination for a waterproof head-mounted display, which is composed of a freezing and heating box, a vacuum air extraction assembly and a water spraying assembly. The present application can achieve the goal of using only water to clean the waterproof head-mounted display after normal operation under the condition of maintaining normal operation of the waterproof head-mounted display, and it also has the characteristics of not needing mechanical brushing, which can avoid scratching the optical display assembly of the waterproof head-mounted display.
[0009] The waterproof head-mounted display provided by the utility model has isolation function, so that the waterproof head-mounted display can continue normal operation in the environment with dirt by isolating the dirt, and the utility model can play obvious industrial utilization in practice.
[0010] The utility model discloses the refrigeration heating box has the internal hollow space of accommodating waterproof head-mounted display, and the space is closed space, and the waterproof head-mounted display is placed in the space and carries out environmental protection cleaning operation.
[0011] The utility model discloses the refrigeration heating box has the internal hollow space of accommodating waterproof head-mounted display, and the space is closed space, and the waterproof head-mounted display is placed in the space and carries out environmental protection cleaning operation.
[0012] The utility model discloses the refrigeration heating box has the internal hollow space of accommodating waterproof head-mounted display, and the space is closed space, and the waterproof head-mounted display is placed in the space and carries out environmental protection cleaning operation.
[0013] The waterproof head-mounted display to which this invention applies is a three-dimensional structure with an irregular shape. Its surface has many uneven corners and spaces that can trap dirt and grime, and these corners are also covered by the transparent waterproof membrane. Therefore, dirt generated during operation of the waterproof head-mounted display will also enter these corners and spaces isolated by the transparent waterproof membrane, making cleaning the surface of the display very troublesome and difficult. Therefore, this invention proposes that a water film sprayed onto the surface of the waterproof head-mounted display can be easily injected into these corners and spaces where dirt and grime can accumulate, filling them completely and effectively covering the dirt. This allows for easier and more environmentally friendly subsequent cleaning operations.
[0014] The water spray component inside the refrigeration and heating chamber of this invention can spray water from multiple directions. Furthermore, the water film can utilize the surface tension of water to create a continuous, uninterrupted water film on the surface of the waterproof head-mounted display in a vacuum state. This increases the probability that the water film can completely cover the dirt on the surface of the waterproof head-mounted display, thus increasing the success rate of the environmentally friendly cleaning function of removing dirt from the surface of the waterproof head-mounted display as claimed in this project.
[0015] The freeze-heating chamber of this invention can cool and lower the temperature, causing the water film covering the surface of the waterproof head-mounted display to freeze into an ice film. After the freezing process is complete, the freeze-heating chamber can heat the ice film to melt it into flowing water. This melting water flows downwards due to gravity, and the surface dirt generated during normal operation of the waterproof head-mounted display can be removed and carried away by the melting water as it flows. This provides an environmentally friendly cleaning function that uses only water to remove dirt adhering to the surface of the waterproof head-mounted display, restoring the surface to a clean state after normal operation.
[0016] The freeze-heating box of this invention can heat the frozen water film to melt it into flowing water. The melted water can flow downwards under the action of gravity. Furthermore, the water spraying component inside the freeze-heating box can simultaneously spray water onto the transparent waterproof film on the surface of the waterproof head-mounted display, which can accelerate the downward flow and dripping speed of the melted water, and also accelerate the removal and removal of dirt from the surface of the waterproof head-mounted display by the water flow.
[0017] The water spraying assembly of the utility model can be a conventional electric motor pressurized water spraying device assembly, which can make water flow pressurized and quickly pass through a conventional nozzle through an electric motor, so that the water flow is sprayed and delivered in multiple directions towards the waterproof head-mounted display. If the nozzle has different diameters or shapes, the water flow can have multiple water column thicknesses, multiple water column appearances, multiple water spraying speeds and multiple water spraying distances.
[0018] The refrigeration and heating box of the utility model is a hollow container, and the space inside the refrigeration and heating box has the functions of cooling and refrigeration and heating and temperature rise. The refrigeration and heating box can have a conventional logic controller (PLC), which can follow a specific operation program according to the set operation process content of the utility model, and can automatically control the number of repeated cooling and heating water spraying cycles and the length of operation time of the refrigeration and heating box.
