[0028] See also Figures 1 to 5 As shown, according to an embodiment of the present invention, a pot cover assembly is provided. The pot cover assembly in this embodiment includes an inner lining 10, an outer pot cover 20, an operating handle (not shown in the figure) and a detection assembly.

[0029] The outer pot cover 20 in the present embodiment has a closing position and an opening position. During actual installation, the outer pot cover 20 is rotatably mounted on the bottom of the inner liner 10, and the operating handle is mounted on the inner liner 10 and is drivingly connected to the outer pot cover 20; the outer pot cover 20 rotates at the bottom of the inner liner 10 to switch between the closing position and the opening position, and the outer pot cover 20 can be rotated at the bottom of the inner liner 10 by the driving action of the operating handle. The detection component is mounted between the inner liner 10 and the outer pot cover 20, and is used to detect whether the outer pot cover 20 is in the closing position or the opening position.

[0030] According to the above structure, it can be known that the detection component in this embodiment is installed between the inner lining 10 and the outer pot cover 20. In the process of performing its detection function, the detection object of the detection component is the position of the outer pot cover 20 rather than other structures and elements. Compared with the previous method of combining the rotating rod structure for detection, the detection element in the pot cover assembly in this embodiment can absolutely detect the closing position and opening position of the outer pot cover 20 without detecting through other intermediate structures. The structure is simple and safer and more reliable. It can be seen that when the detection component of the present invention does not detect a signal, defective products can be detected through production control, thereby ensuring that the closing of the lid will inevitably detect a signal, achieving the purpose of absolutely safe closing of the lid.

[0031] The detection component in this embodiment includes a lid closing signal sending part and a lid closing signal receiving part. When the lid closing signal receiving part receives the signal sent by the lid closing signal sending part, the outer pot cover 20 is in the lid closing position. When the lid closing signal receiving part does not receive the signal sent by the lid closing signal sending part, the outer pot cover 20 is in the lid opening position.

[0032] In one embodiment of the present invention, the cover closing signal sending part is set as the touch part, and the cover closing signal receiving part is set as the micro switch 11; in actual installation, one of the micro switch 11 and the touch part is installed on the inner lining 10, and the other of the two is installed on the outer pot cover 20. When the outer pot cover 20 rotates, if the touch part touches the micro switch 11, then the outer pot cover 20 is in the cover closing position, and if the touch part does not touch the micro switch 11, it means that the outer pot cover 20 is in the cover opening position.

[0033] Combination Figures 3 to 5 As shown, the micro switch 11 in this embodiment is arranged on the inner lining 10, and the triggering part is arranged on the outer pot cover 20. This is because the micro switch 11 itself is installed with structures such as a power cord, and the micro switch 11 is installed on the inner lining 10, which can prevent the power cord from interfering or pulling when the micro switch 11 moves, and the triggering part itself is only a structure that can trigger the micro switch 11. The triggering part is arranged on the rotatable outer pot cover 20, which is convenient for triggering the micro switch 11 when the outer pot cover 20 rotates to the closed position, and the structure is simple, which is convenient for processing and design.

[0034] Preferably, the triggering part in this embodiment is a convex bump 21 arranged on the edge of the outer pot cover 20. Of course, in other embodiments of the present invention, the triggering part can also be set as a triggering rod or other structures, as long as other deformation modes under the concept of the present invention are within the protection scope of the present invention.

[0035] In order to install the micro switch 11 , a positioning hole 12 is provided on the inner lining 10 in this embodiment. During installation, the micro switch 11 is directly installed in the positioning hole 12 , which facilitates positioning of the micro switch 11 .

[0036] The side wall of the positioning hole 12 in this embodiment is provided with an avoidance hole 13 connected with the positioning hole 12, and the contact of the micro switch 11 extends out of the avoidance hole 13. When the outer pot cover 20 rotates at the bottom of the lining 10, it is easy to drive the convex bump 21 to touch the micro switch 11. The structure is simple and easy to implement.

[0037] Preferably, in order to facilitate the triggering of the micro switch 11, a mounting hole is provided at the bottom of the inner lining 10 in this embodiment. When designed, the avoidance hole 13 horizontally connects the mounting hole and the positioning hole 12, and the convex bump 21 is provided at the outer edge of the outer pot cover 20. When the outer pot cover 20 rotates, the convex bump 21 is convenient for triggering the micro switch 11. Of course, in other embodiments of the present invention, the mounting hole may not be provided, and the avoidance hole 13 may be provided at the bottom of the positioning hole 12, and the convex bump 21 may be provided at the top of the outer pot cover 20 accordingly. As long as it is other deformation methods under the conception of the present invention, they are all within the protection scope of the present invention.

[0038] Combination Figure 1 and Figure 2 , Figure 4 and Figure 5 As shown, the pot cover assembly further includes a pressing plate 30. When installed, the micro switch 11 is pressed into the positioning hole 12 by the pressing plate 30, which is convenient for installation and positioning. Of course, in other embodiments of the present invention, the pressing plate 30 may not be provided, and the micro switch 11 may be fixed into the positioning hole 12 by a fastener, and the fastener may be a structure such as a screw, a pin or a rivet.

[0039] The convex bump 21 in this embodiment can be welded after being processed separately or fixed on the outer pot cover 20 through other fixing parts, or can be integrally formed with the outer pot cover 20. Preferably, the surface of the convex bump 21 in this embodiment is a smooth convex arc surface, which can not only rotate with the outer pot cover 20 to trigger the micro switch 11, but also prevent the convex bump 21 from interfering with the micro switch 11.

[0040] In another embodiment of the present invention that is not shown, the cover closing signal sending part is set as a magnetic element, and the cover closing signal receiving part is correspondingly set as a reed switch. In actual installation, the magnetic element is installed on the outer pot cover 20, and the reed switch is installed on the inner lining 10. When the outer pot cover 20 drives the magnetic element to move to the cover closing position, the magnetic element sends a signal to the reed switch, and the reed switch receives the signal of the magnetic element to detect that the outer pot cover 20 is in the cover closing position. When the outer pot cover 20 drives the magnetic element to move to the cover opening position, the reed switch cannot receive the signal of the magnetic element. At this time, the detection component detects that the outer pot cover 20 is in the cover opening position.

[0041] Preferably, the magnetic element in this embodiment is a magnet, which has a simple structure and is easy to implement.

[0042] Recombination Figures 1 to 5 As shown, the micro switch 11 in the present invention is assembled on the inner lining 10, the pressing plate 30 fixes the micro switch 11 on the inner lining 10, and the outer pot cover 20 is assembled on the bottom of the inner lining 10. When in use: the outer pot cover 20 rotates and has two positions, the cover-closed position and the cover-opened position. The convex bump 21 on the outer pot cover 20 gives a signal when rotating and the relative position of the micro switch 11, so as to achieve the purpose of giving a signal when the outer pot cover 20 is screwed on, and the signal can be received even when the outer pot cover 20 is not screwed on, thereby ensuring the safety of the product.

[0043] According to another aspect of the present invention, a cooking utensil is provided, and the cooking utensil is particularly an electric pressure cooker. The electric pressure cooker comprises a pot cover assembly, and the pot cover assembly is the pot cover assembly in the above embodiment.

[0044] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0045] The present invention directly assembles the magnetic parts on the outer pot cover, or gives a signal through the characteristics of the outer pot cover itself, such as a convex structure, which gives a signal when the outer pot cover is screwed into place, and a part for receiving the signal is arranged on the inner lining, which can be a reed switch, or an electrical device such as a micro switch. In this way, there will only be two results, one is that the signal is detected when the cover is closed, and the second is that the signal cannot be detected when the cover is not closed. If the signal is not detected, defective products can be detected through production control, thereby ensuring that the signal will be detected when the cover is closed, so as to achieve the purpose of absolute safety of closing the cover.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
