Description

Technical Field

[0001] The utility model relates to the technical field of sterilizing kettles, in particular to a cover-opening pressure relief device for a sterilizing kettle. Background Art

[0002] The sterilization kettle, also known as the sterilization pot or sterilizer, mainly uses steam under a certain pressure as the heat source to sterilize the product. It has the characteristics of large heating area, high thermal efficiency, uniform heating, short liquid boiling time, and easy control of heating temperature. It is widely used in the food and pharmaceutical fields.

[0003] After the sterilization of the sterilizer, due to the combined effect of internal heat and steam, the internal pressure is greater than the external pressure. During the process of opening the lid of the sterilizer, the internal steam will escape and scald the staff. However, most of the existing pressure relief devices for opening the lid relieve pressure through opening holes. However, this pressure relief method still causes some steam to escape during the process of opening the lid of the sterilizer, resulting in poor use effect. Therefore, we propose a pressure relief device for opening the lid of the sterilizer to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a pressure relief device for opening the lid of a sterilizing kettle, so as to solve the problem that most of the current pressure relief devices for opening the lid proposed in the above-mentioned background technology release pressure by opening holes, but in this pressure relief method, some steam still escapes during the process of opening the lid of the sterilizing kettle, resulting in poor use effect.

[0024] See also Figure 1-4 The utility model provides a technical solution: a cover-opening pressure relief device for a sterilizing kettle, comprising: a mounting plate 1, a pressure relief box 2, a pressure relief pipe 3, a valve plate 4, a connecting rod 5, a handle 6, a rack 7, a first gear 8, a mounting box 9, a spring shaft 10, a second gear 11, a third gear 12, a fan blade 13, a connecting rope 14 and a winding roller 15;

[0025] A mounting plate 1, a pressure relief box 2 is mounted on the top of the mounting plate 1, and a pressure relief pipe 3 is fixedly connected to the top right side of the pressure relief box 2, a valve plate 4 is arranged at the bottom of the pressure relief pipe 3, and a connecting rod 5 is fixedly connected to the left end of the valve plate 4, a handle 6 is connected to the left end of the connecting rod 5, and a rack 7 is fixedly connected to the bottom of the handle 6, a first gear 8 is arranged on the left side of the mounting plate 1, and a winding roller 15 is connected to the top of the first gear 8;

[0026] The installation box 9 is arranged inside the pressure relief box 2, and a clockwork shaft 10 is arranged inside the installation box 9, the shaft end of the clockwork shaft 10 is connected to the second gear 11, and a third gear 12 is arranged on the outer side of the second gear 11, and a fan blade 13 is fixedly installed on the top of the third gear 12, the clockwork driving end of the clockwork shaft 10 is fixedly connected to a connecting rope 14, and the other end of the connecting rope 14 is connected to the winding roller 15.

[0027] like Figure 1 and Figure 2Hole structures are provided at the four corners of the middle mounting plate 1, and the mounting plate 1 and the pressure relief box 2 are integrated into an integrated structure, which is convenient for the installation of the mounting plate 1. The valve plate 4 and the pressure relief pipe 3 form a telescopic structure, and the handle 6 forms a linkage mechanism with the valve plate 4 through the connecting rod 5, which is convenient for controlling the conduction of the pressure relief pipe 3. The left end of the handle 6 passes through the left end of the pressure relief box 2, and the handle 6 is slidingly and sealingly connected to the pressure relief box 2, which is convenient for the operation of the handle 6.

[0028] like Figure 1 , Figure 3 and Figure 4 The middle rack 7 is meshedly connected with the first gear 8, and the handle 6 forms a transmission mechanism with the clockwork shaft 10 through the rack 7, the first gear 8 and the connecting rope 14, which is convenient for driving the first gear 8 to rotate. The diameter of the second gear 11 is larger than the diameter of the third gear 12, and the clockwork shaft 10 forms a transmission mechanism with the fan blades 13 through the second gear 11 and the third gear 12, and the first gear 8 and the second gear 11 are both ratchet gears, which is convenient for driving the fan blades 13 to rotate. The fan blades 13 are located inside the bottom end of the pressure relief pipe 3, and the pressure relief pipe 3 is arranged in a "convex" structure, which is convenient for driving air circulation.

[0029] Working principle: When using the opening pressure relief device of the sterilizer, Figure 1 As shown, by manually pulling the handle 6, the handle 6 drives the valve plate 4 to move through the connecting rod 5, and the opening of the pressure relief pipe 3 is opened to facilitate pressure relief. While the handle 6 moves, the rack 7 drives the first gear 8 to rotate, so that the first gear 8 drives the winding roller 15 to rotate, and the connecting rope 14 is pulled, thereby pulling the spring of the spring shaft 10, and the spring shaft 10 is tightened and charged. Since the first gear 8 and the second gear 11 are both ratchet gears, the first gear 8 and the second gear 11 are convenient for unidirectional rotation;

[0030] After the rack 7 is separated from the first gear 8, Figure 1 As shown, the spring of the clockwork shaft 10 is reset, driving the shaft of the clockwork shaft 10 to rotate, thereby driving the second gear 11 to rotate, and the second gear 11 drives the fan blade 13 to rotate through the third gear 12 to extract the steam and prevent part of the steam from leaking out from the cover door opening. While the spring of the clockwork shaft 10 is reset, the connecting rope 14 is recovered to facilitate the next use. When the handle 6 is reset, the unidirectional rotation of the first gear 8 prevents the first gear 8 from driving the winding roller 15 to rotate in the opposite direction. This is the entire working process of the opening and pressure relief device of the sterilizing kettle.
