[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The present invention is further described in detail below in conjunction with the embodiments.

[0019] like Figure 1-3 As shown, a specific embodiment of a mobile phone waterproof bag that can be vacuumed and has a touch screen underwater provided by the utility model:

[0020] A mobile phone waterproof bag that can be vacuumed and has a touch screen underwater, comprising a bag cover 1 and a clamping assembly 2, wherein the clamping assembly 2 is used to clamp the bag opening of the sealed bag cover 1, and the bag cover 1 is provided with an installation opening, and an air extraction valve assembly 3 is installed at the installation opening;

[0021] The exhaust valve assembly 3 includes a base 4 and an outer cover 5. The base 4 is fixed to the installation port, and the outer cover 5 is installed on the base 4 by threads. An exhaust hole 6 is opened at the bottom of the base 4, and the exhaust hole 6 is connected to the installation port. The exhaust hole 6 is used to install a one-way valve 7.

[0022] When in use, put the mobile phone into the bag cover 1, and then use the clamping assembly 2 to seal the bag mouth of the bag cover 1, and then extract the gas in the bag cover 1 through the exhaust hole 6 to form a vacuum state inside the bag cover 1. The one-way valve 7 only allows the gas to be discharged outward, and the gas cannot enter the bag cover 1 through the one-way valve 7. After exhausting the air, the sealing condition of the bag cover 1 can be known by observing whether the bag cover 1 is bulging. If it is bulging, it proves that gas has entered the bag cover 1, which proves that the sealing of the mobile phone waterproof bag is poor. The user can replace a new mobile phone waterproof bag; after vacuuming, the mobile phone can be better fixed in the bag cover 1, and the operation is more sensitive and convenient. In addition, there is no gas in the bag cover 1, which can prevent the temperature in the bag cover 1 from dropping and forming water mist, which affects the shooting of the mobile phone.

[0023] In order to facilitate the vacuuming of the bag cover 1 through the vacuum hole 6, the present embodiment also involves a press-and-pump assembly, which is arranged on the bag cover 1 and is manually operated and easy to use. The specific structure is as follows: the press-and-pump assembly includes a spring 8 and a piston button 9, both of which are located in the base 4, and the outer end of the outer cover 5 has an inner ring edge 10. The piston button 9 can move along its axial direction in the base 4, and the end of the piston button 9 passes outward from the inner ring edge 10 of the outer cover 5. The inner ring edge 10 prevents the piston button 9 from escaping from the outer cover 5. The spring 8 is installed between the bottom of the base 4 and the piston button 9, and a rubber ring 11 is installed at the end of the piston button 9 located in the base 4.

[0024] The method of using the press-to-evacuate assembly to perform vacuum operation is as follows: press the piston button 9 to squeeze out the gas in the internal cavity of the base 4, forming a negative pressure inside the base 4, compressing the spring 8, releasing the piston button 9, and the piston button 9 resets under the elastic force of the spring 8. The negative pressure can be used to extract the air inside the bag cover 1 through the one-way valve 7 and the vacuum hole 6. By repeatedly pressing the piston button 9, the inside of the bag cover 1 can be evacuated to a vacuum.

[0025] As another embodiment of the present utility model, Figure 4 As shown, the bag cover 1 is formed by pressing an upper film and a lower film together, the upper film is a transparent film, the transparent film includes an outer film layer 12, an inner film layer 13 and an intermediate film layer 14, the intermediate film layer 14 is located between the outer film layer 12 and the inner film layer 13, the intermediate film layer 14 is a non-conductive transparent gel layer or an insulating oil layer, the outer film layer 12 and the inner film layer 13 are PVC film or TPU film, and the three-layer structure of the transparent film can effectively prevent water droplets from conducting electricity, so that the mobile phone screen can be normally touched and controlled on rainy days or underwater, and is widely used in takeout, express delivery and other personnel to operate mobile phones on rainy days, as well as underwater snorkeling and taking pictures.

[0026] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
