[0018] 1. The utility model is provided with a liquid level switch device, which is conducive to automatically sending a valve closing signal according to the liquid level height, avoiding the situation that the beer concentrate is overflowed due to the manual valve closing failure in time. The floating plate is movably arranged on the upper end of the limit ring.

The rotating motor drives the rotating bevel gear and the transmission bevel gear to run, thereby driving the scratch frame to rotate. The lower end of the scratch frame is limited by the limit sleeve and the limit block, thereby realizing the limited rotation of the scratch frame. The waterproof cover can prevent the beer concentrate from adhering to the rotating bevel gear and the transmission bevel gear to cause oxidation corrosion, thereby achieving the overall effect of automatically scratching the inside of the shell.

DETAILED DESCRIPTION

[0025] 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 them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the field of beer preservation and deoxygenation without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 and 2As shown, the utility model provides a beer preservation and deoxygenation device, including a shell 1: a rotating motor 6 is fixedly provided on one side of the lower end of the shell 1 through a flange, and the output end of the rotating motor 6 passes through the outer wall of the shell 1; a limiting ring 14 is fixedly provided on the inner wall of the shell 1, and a scratch frame 13 is movably provided on the inner side of the shell 1; a feed pipe 4 is connected to the lower end of one side of the shell 1, and a first solenoid valve 5 is fixedly provided on the outer surface of the feed pipe 4; a carbon dioxide discharge pipe 11 is connected to the upper end of one side of the shell 1, and a second solenoid valve 12 is fixedly provided on the outer surface of the carbon dioxide discharge pipe 11; a vacuum pump 9 is fixedly provided on the upper end of the shell 1, and an exhaust pipe 10 is fixedly provided on the output end of the vacuum pump 9; an oxygen detector 8 and a pressure detector 7 are fixedly provided on one side of the upper end of the shell 1.

[0027] In order to avoid the situation where the original beer liquid overflows due to the manual valve not being closed in time, two liquid level switch devices 2 capable of transmitting automatic valve closing signals are respectively provided on both sides of the inner wall of the housing 1, which are used to automatically send out valve closing signals according to the liquid level height;

[0028] like Figure 3 As shown, the liquid level switch device 2 includes a floating plate 21, which is movably arranged on the inner side of the housing 1. The floating plate 21 is located at the upper end of the limit ring 14. Two sliding switch generators 22 are fixedly arranged on both sides of the inner wall of the housing 1. A switch rod 23 is movably arranged at the input end of the sliding switch generator 22. A spring 24 is movably arranged on the outer surface of the switch rod 23. The spring 24 is located at the lower end of the sliding switch generator 22 and is movably arranged at the upper end of the limit ring 14 through the floating plate 21. Therefore, when the beer concentrate is injected into the housing 1 through the feeding pipe 4, the liquid level rises, thereby driving the floating plate 21 to rise. When the floating plate 21 is rising, the two switch rods 23 on top slide upward. Therefore, the two sliding switch generators 22 send signals to the first solenoid valve 5 and the vacuum pump 9 respectively, thereby closing the first solenoid valve 5 and starting the vacuum pump 9. Therefore, the trouble of manual valve closing is reduced, and the problem of beer concentrate overflowing due to untimely manual valve closing can be prevented.

[0029] Furthermore, in order to automatically clean the inner wall of the housing 1, an inner wall cleaning device 3 capable of scraping the inner wall of the housing 1 is provided at the lower inner end of the housing 1, and is used to scrape the inner wall of the housing 1 for automatic cleaning;

[0030] like Figure 4As shown, the inner wall cleaning device 3 includes a connecting plate 36, both ends of the connecting plate 36 are fixedly connected to the inner wall of the shell 1, a waterproof cover 31 is fixedly provided at the lower end of the connecting plate 36, the output end of the rotating motor 6 passes through one side of the waterproof cover 31, and a rotating bevel gear 32 is fixedly provided at the output end of the rotating motor 6. The lower end of the scratch frame 13 passes through the upper end of the waterproof cover 31, and a limiting sleeve 35 is fixedly provided at the upper end of the connecting plate 36. The inner wall of the limiting sleeve 35 is movably connected to the outer surface of the lower end of the scratch frame 13, and two limiting blocks 34 are fixedly provided on the outer surface of the scratch frame 13, and the two limiting blocks 34 are respectively located at the limiting The upper end of the positioning sleeve 35 and the upper end of the inner wall of the waterproof cover 31, and the lower end of the scratch frame 13 are fixedly provided with a transmission bevel gear 33, and the transmission bevel gear 33 is meshingly connected with the rotating bevel gear 32, and the rotating bevel gear 32 and the transmission bevel gear 33 are driven by the rotating motor 6 to operate, thereby driving the scratch frame 13 to rotate, because the lower end of the scratch frame 13 is limited by the limiting sleeve 35 and the limiting block 34, thereby realizing the limited rotation of the scratch frame 13, and the waterproof cover 31 can prevent the beer concentrate from adhering to the rotating bevel gear 32 and the transmission bevel gear 33, causing oxidation corrosion, thereby realizing the overall effect of automatically scratching the interior of the shell 1.

[0031] The working principle is as follows: when the utility model is in use, the beer concentrate is input into the utility model through the feed pipe 4 by opening the first solenoid valve 5, the first solenoid valve 5 is automatically closed by the liquid level switch device 2, the vacuum pump 9 is started, the pressure detector 7 and the oxygen detector 8 are observed, and when the pressure detector 7 displays a negative pressure and the oxygen detector 8 detects a low oxygen content, the second solenoid valve 12 is opened, and carbon dioxide is discharged into the utility model through the carbon dioxide discharge pipe 11. Since the mass of carbon dioxide is greater than the mass of oxygen, oxygen is discharged into the upper end of the interior of the utility model and extracted by the vacuum pump 9. When the oxygen detector 8 detects that the oxygen content is 0, the vacuum pump 9 and the second solenoid valve 12 are closed, thereby achieving the beer preservation effect. When the utility model is idle, the inner wall is scratched and cleaned by the inner wall cleaning device 3, thereby reducing the trouble of manual cleaning.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
