Description

Technical Field

[0001] The utility model belongs to the technical field of pressure cookers, and in particular relates to a safe knob-opening and closing pressure cooker. Background Art

[0002] A pressure cooker, also known as a pressure cooker or pressure cooker, is a kitchen appliance. It uses the physical phenomenon that the boiling point of liquids increases under higher air pressure. By sealing and applying pressure to the water, it reaches a higher temperature without boiling, thereby speeding up the efficiency of stewing food. In this way, the pressure cooker can make the temperature of food exceed 100℃, which helps to cook food faster and more energy-efficiently. In addition, in high altitude areas, pressure cookers are particularly important because they can prevent the boiling point of water from decreasing, thereby ensuring that food can be fully cooked.

[0003] At present, the knob-type pressure cooker is generally opened by rotating the knob on the lid, which drives the clamping edge that cooperates with the pot edge to move relative to each other, thereby opening or locking the lid. However, the knob of the pressure cooker lacks safety protection, so the knob is easy to rotate when accidentally touched, and the lid is accidentally opened, causing hot steam to leak, posing a safety hazard.

DETAILED DESCRIPTION

[0021] 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.

[0022] See also Figure 1-7The utility model provides a safe knob opening and closing pressure cooker, comprising a pot body 1 and a pot cover 2, wherein the pot body 1 is provided with a pot edge 3 along the upper end thereof, and the pot cover 2 is provided with clamping edges 4 on both sides thereof which can clamp the bottom of the pot edge 3, and the pot cover 2 is provided with adjusting plates 5 respectively fixedly connected with the two clamping edges 4, and the adjusting plates 5 are hingedly connected with connecting pieces 6 above one end away from the clamping edges 4, and the ends of the two connecting pieces 6 are hingedly connected with the two ends of the connecting plate 8 through adjusting columns 7, and the pot cover 2 is provided with a cover plate 9 covering the adjusting plates 5, and the cover The center of the plate 9 is provided with a mounting groove 10, the center of the connecting piece 6 is rotatably connected with a connecting column 11, the top of the connecting column 11 passes through the mounting groove 10, a positioning frame 12 is installed in the mounting groove 10, a knob 13 rotatable outside the positioning frame 12 is installed on the mounting groove 10, a positioning hole is provided at the bottom of the knob 13 so that the top of the adjusting column 7 extends into it, a button 14 is installed on the knob 13, and a positioning convex piece 15 is provided at the bottom of the button 14, and a positioning groove adapted to the positioning convex piece 15 is provided on the cover plate 9 16, the top of the connecting column 11 is equipped with a limiting mechanism connected to the bottom of the button 14; when in use, when it is necessary to rotate the knob 13 in the mounting groove 10 of the cover plate 9, the button 14 is pressed inwardly, so that the positioning protrusion 15 is disengaged from the limit of the positioning groove 16, and then the button 14 can be rotated relative to the cover plate 9. When the knob 13 and the button 14 rotate, since the bottom of the button 14 locates the top of the adjusting column 7 through the positioning groove, the two adjusting columns 7 will be driven to rotate from the center. When the adjusting column 7 rotates, it will drive the two connecting pieces 6 to swing. The two adjusting plates 5 are driven to move relative to each other, thereby adjusting the distance between the two clamping edges 4. When the clamping edge 4 is separated from the pot edge 3, the pot cover 2 can be opened. The same principle applies to closing the pot cover 2 by rotating the knob 13 in the opposite direction. When the rotation is in place, release the pressing button 14 to reset it and make the positioning protrusion 15 clamped in the positioning groove 16 again. Due to the limitation of the positioning protrusion 15 and the positioning groove 16, when the button 14 is not pressed, the knob 13 cannot rotate relative to the cover plate 9, thereby failing to complete the rotation action, thereby improving the safety of the pressure cooker.

[0023] Specifically, a guide frame 17 is installed on the pot cover 2, and the guide frame 17 forms a guide groove in the middle through front and rear ribs so that the two adjustment plates 5 can only slide along it; in this embodiment, the adjustment plate 5 is limited so that it can only slide along the guide groove.

[0024] Specifically, the positioning frame 12 is provided with a reinforcing rib 18, a spring 19 is fixed on the reinforcing rib 18, a connecting head 20 partially inserted into the spring 19 is fixed on the button 14, and a blocking strip 21 is provided on the outer wall of the part of the connecting head 20 not inserted into the spring 19; in this embodiment, after being rotated into place, the pressing button 14 is released, and the spring 19 elastically resets itself, thereby driving the button 14 to reset through the connecting head 20, and causing the positioning protrusion 15 to be re-stuck in the positioning groove 16.

[0025] Specifically, a rotating groove 22 for the adjusting column 7 to pass through is provided in the installation groove 10, and the two adjusting columns 7 can rotate along the rotating groove 22; in this embodiment, when the knob 13 and the button 14 rotate, the bottom of the button 14 locates the top of the adjusting column 7 through the positioning groove, thereby driving the two adjusting columns 7 to rotate from the center in the rotating groove 22.

[0026] Specifically, the limiting mechanism includes an annular baffle 23 installed at the top of the connecting column 11, and a screw 24 fixing the annular baffle 23. The button 14 is provided with a groove for the connecting column 11 to pass through, and the annular baffle 23 covers the groove. The button 14 can move horizontally relative to the connecting column 11 through the groove. In this embodiment, the annular baffle 23 is used to limit the up and down movement of the button 14 so that it can only move horizontally.

[0027] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0028] Working principle: When in use, when it is necessary to rotate the knob 13 in the mounting groove 10 of the cover plate 9, the button 14 is pressed inwardly, so that the positioning protrusion 15 is disengaged from the limit of the positioning groove 16, and then the button 14 can rotate relative to the cover plate 9. When the knob 13 and the button 14 rotate, since the bottom of the button 14 locates the top of the adjustment column 7 through the positioning groove, the two adjustment columns 7 will be driven to rotate in the rotation groove 22 from the center. When the adjustment column 7 rotates, it will drive the two connecting pieces 6 to swing, thereby driving the two adjustment plates 5 to make relative movement, thereby adjusting the two The pot cover 2 can be opened by rotating the knob 13 in the opposite direction when the pot cover 2 needs to be closed. When the knob 13 is rotated to the right position, the button 14 is released. The spring 19 is reset due to its own elastic force, and the button 14 is reset through the connector 20, and the positioning protrusion 15 is re-engaged in the positioning groove 16. Due to the limitation of the positioning protrusion 15 and the positioning groove 16, when the button 14 is not pressed, the knob 13 cannot rotate relative to the cover plate 9, and the rotation action cannot be completed, thereby improving the safety of the pressure cooker.

[0029] Although 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.
