In addition, the terms "first" and "second" are only used for descriptive distinction and have no special meanings.

[0051] The embodiment of the present utility model discloses a sealing connection mechanism, a spraying device and a cooking appliance.

[0052] Referring to Figures 1 to 5 , the sealing connection mechanism includes a sealing component 1, a conducting pipe 2 and a connecting pipe 3. The sealing component 1 is arranged in the inner container 4 and can seal the mounting hole 41 of the inner container 4; the conducting pipe 2 passes through the sealing component 1 and is sealingly connected to the sealing component 1, and one end of the conducting pipe 2 is communicated with a liquid injection device 5; the connecting pipe 3 is sleeved on the other end of the conducting pipe 2 and is rotatably connected to the conducting pipe 2, and the end of the connecting pipe 3 away from the conducting pipe 2 is connected to a spraying part 6 inside the inner container 4 through the mounting hole 41 to divert the cleaning liquid in the conducting pipe 2 to the spraying part 6.

[0053] Specifically, the mounting hole 41 can be opened on the side wall, bottom wall or top wall of the inner container 4. In this embodiment, taking the mounting hole 41 opened at the middle position of the top wall of the inner container 4 as an example. The sealing assembly 1 is arranged on the outer top wall of the inner container 4, and it can be fixed by locking parts such as bolts, or can be fixed by a clamping structure or sealant and other means. The conduction pipe 2 passes through the sealing assembly 1, and its upper end is used to communicate with the liquid injection pipe 51 of the liquid injection device 5. The liquid injection pipe 51 can be directly inserted into the conduction pipe 2, or can be communicated with the conduction pipe 2 through a sealing joint. The lower end of the conduction pipe 2 is rotatably connected with a connecting pipe 3. The connecting pipe 3 can be located inside the inner container 4, or can partially extend into the inner container 4 or be completely located outside the inner container 4. The spraying part 6 has a threaded pipe threadedly connected with the connecting pipe 3. One end of the threaded pipe away from the connecting pipe 3 has a spray head. The inside of the spray head has a liquid storage cavity communicated with the connecting pipe 3. The connecting pipe 3 guides the cleaning liquid into the spraying part 6. When the cleaning liquid sprays out from the spraying part 6, it can generate a thrust force to push the spraying part 6 to rotate. In other embodiments, a driving structure can also be separately provided for the spraying part 6 to drive the spraying part 6 to rotate, such as motor driving, etc.

[0054] Through the setting of the sealing assembly 1, the sealing assembly 1 can seal the mounting hole 41 and at the same time form a sealed connection with the conduction pipe 2, ensuring that the steam or oil fume inside the inner container 4 will not overflow outward through the mounting hole 41. The conduction pipe 2 is rotatably connected with the connecting pipe 3, and the connecting pipe 3 is then connected with the spraying part 6, which can not only enable the spraying part 6 to have the freedom of rotation, but also ensure that during the rotation of the spraying part 6, the liquid injection device 5 can continuously input the cleaning liquid into the spraying part 6 through the conduction pipe 2 and the connecting pipe 3. In this way, when the sealed connection mechanism is in use, it can continuously provide the cleaning liquid for the rotating spraying part 6 to ensure the continuity of cleaning, and can also effectively seal the mounting hole 41 of the inner container 4 by using the sealing assembly 1 to ensure that steam and oil fume will not overflow at the mounting hole 41, thereby effectively protecting the circuit module arranged outside the inner container 4 and ensuring that the user can use it normally.

[0055] Optionally, the sealing assembly 1 includes a sealing frame 11. The sealing frame 11 is arranged on the inner container 4 and is hermetically connected with the inner container 4. The sealing frame 11 has a mounting cavity communicated with the mounting hole 41, and the conduction pipe 2 is inserted into the mounting cavity and is hermetically connected with the cavity wall of the mounting cavity.

[0056] Specifically, the sealing frame 11 is annular, and its interior is hollow to serve as an installation cavity, which corresponds to and communicates with the installation hole 41. A plurality of fixing lugs 111 are arranged at intervals in a ring on the outer side wall of the sealing frame 11. Fixing screws are inserted through the fixing lugs 111, and the fixing screws can be threadedly connected to the outer top wall of the inner tank 4 to fix the sealing frame 11 on the outer top wall of the inner tank 4. In this embodiment, two fixing lugs 111 are arranged oppositely. A surface fit is formed between the sealing frame 11 and the outer side wall of the inner tank 4 to form a sealed connection. A sealing structure can also be arranged between the sealing frame 11 and the inner tank 4 to enhance the sealing effect. Similarly, the sealed connection between the installation cavity and the conduction pipe 2 can also be achieved in the above manner.

[0057] By providing the sealing frame 11, when the sealing frame 11 is fixed to the outer top wall of the inner tank 4 by bolts, the sealing frame 11 can form a sealed connection with the inner tank 4 and the sealing frame 11, and an installation cavity is formed within the sealing frame 11 to provide an installation space for the conduction pipe 2 and to provide a guiding function for the insertion of the conduction pipe 2 into the installation hole 41. Then, through the sealed connection between the installation cavity and the conduction pipe 2, the gap between the sealing frame 11 and the inner tank 4 is closed.

[0058] Optionally, the sealing assembly 1 further includes a first sealing portion 12. One side of the first sealing portion 12 abuts against the sealing frame 11, and the other side abuts against the outer side wall of the inner tank 4 to close the installation hole 41.

[0059] The first sealing portion 12 is arranged between the bottom wall of the sealing frame 11 and the outer top wall of the inner tank 4. The first sealing portion 12 can be annular, and its shape is adapted to that of the sealing frame 11. The bottom wall of the first sealing portion 12 is attached to the outer top wall of the inner tank 4. The top wall of the first sealing portion 12 is recessed to form a first groove, and the bottom wall of the sealing frame 11 is also recessed to form a second groove. The first groove and the second groove can be inserted and matched with each other. The first sealing portion 12 can be made of elastic rubber material, or can be made of other materials that meet the sealing requirements.

[0060] Optionally, the sealing assembly 1 further includes a second sealing portion 13. The second sealing portion 13 is arranged in the installation cavity, and the conduction pipe 2 passes through the second sealing portion 13. The inner side of the second sealing portion 13 is in sealed fit with the outer side wall of the conduction pipe 2, and the outer side of the second sealing portion 13 is in sealed fit with the cavity wall of the installation cavity.

[0061] Specifically, the second sealing portion 13 can also be made of elastic rubber material. The whole of it can be embedded in the installation cavity. The outer side wall of the second sealing portion 13 abuts against the cavity wall of the installation cavity and forms an interference fit. A through hole is arranged in the middle of the second sealing portion 13 for the conduction pipe 2 to pass through. A sealed connection can also be formed between the second sealing portion 13 and the conduction pipe 2 through an interference fit.

[0062] By providing the first sealing portion 12 and the second sealing portion 13, the first sealing portion 12 can effectively strengthen the gap between the sealing frame 11 and the inner tank 4, and the second sealing portion 13 closes the gap between the conduction pipe 2 and the sealing frame 11, thereby further improving the overall sealing effect.

[0063] Optionally, the outer side surface of the conduction pipe 2 has a limiting plane 21, and the sealing frame 11 has a clamping plane 116 that fits with the limiting plane 21 to limit the rotation of the conduction pipe 2.

[0064] Specifically, the conduction pipe 2 is a circular pipe, and its outer surface is machined axially to form the limiting plane 21, so that the outer shape of the conduction pipe 2 is in a D shape. Correspondingly, a D-shaped through hole is also designed on the inner side of the installation cavity to form the clamping plane 116.

[0065] In this way, through the cooperation of the limiting plane 21 and the clamping plane 116, the rotation of the conduction pipe 2 can be effectively restricted, and there is no need to separately provide a limiting structure, effectively simplifying the complexity of the overall structure. It should be understood that in other embodiments, the conduction pipe 2 can also be a square pipe or other tubular structures with a flat outer side surface, and the shape of the installation cavity can be designed according to the outer shape of the conduction pipe 2.

[0066] Optionally, the outer side wall of the second sealing portion 13 has a limiting groove 131, and the wall of the installation cavity has a limiting block 112 that cooperates with the limiting groove 131 to limit the axial displacement of the second sealing portion 13.

[0067] Specifically, the limiting groove 131 is provided at the middle position of the outer side wall of the second sealing portion 13 along its axis. The limiting groove 131 can be annular or in the shape of a blind hole and arranged in multiple intervals in a ring shape. The wall of the installation cavity protrudes inward to form the limiting block 112, and the limiting block 112 can abut against the side wall of the limiting groove 131 to limit the displacement of the limiting block 112 in the axial direction.

[0068] Optionally, the outer side wall of the conduction pipe 2 has a clamping groove, and the sealing frame 11 further includes an installation portion 113, an installation plate 114, and a clamping portion 115. The installation cavity is opened in the installation portion 113. The installation plate 114 is arranged in the installation cavity, and the conduction pipe 2 passes through the installation plate 114; the clamping portion 115 abuts against the installation plate 114 and is clamped in the clamping groove to limit the axial displacement of the conduction pipe 2.

[0069] Specifically, the installation part 113 is in the shape of a sleeve, and its interior is hollow to serve as an installation cavity. The installation plate 114 is fixed inside the installation cavity. The installation plate 114 and the installation part 113 can be of an integral structure. The second sealing part 13 is placed on the top wall of the installation plate 114. A D-shaped through hole is provided in the middle of the installation plate 114, and the conduction pipe 2 passes through the through hole. The installation plate 114 protrudes upward at the edge position of the through hole to form a ring platform. A clamping part 115 is provided on the ring platform. The clamping part 115 abuts against the top wall of the ring platform. A clamping groove is provided at the position of the conduction pipe 2 corresponding to the clamping part 115. The clamping part 115 can be partially inserted into the clamping groove to limit the axial displacement of the conduction pipe 2. The clamping part 115 can be annular, block-shaped, or rod-shaped, and the shape of the clamping groove can be correspondingly provided.

[0070] Optionally, the conduction pipe 2 is inserted into the connecting pipe 3, and one end of the conduction pipe 2 inserted into the connecting pipe 3 has a connecting protrusion 22. A snap ring 31 is provided at the opening of the connecting pipe 3. The top wall of the connecting protrusion 22 is rotationally fitted with the bottom wall of the snap ring 31.

[0071] Specifically, an annular connecting protrusion 22 is formed by the outward protrusion of the outer side wall at the lower end of the conduction pipe 2. The upper end of the connecting pipe 3 is bent inward to form a snap ring 31 that cooperates with the connecting protrusion 22. The snap ring 31 is rotationally fitted with the connecting protrusion 22 to achieve the rotational connection between the conduction pipe 2 and the connecting pipe 3.

[0072] In this way, by extending the conduction pipe 2 into the connecting pipe 3, it is ensured that the cleaning liquid is directly injected into the connecting pipe 3, and the rotational connection between the two is achieved through the self-structures of the conduction pipe 2 and the connecting pipe 3, without the need to additionally set up a connecting structure to connect the two, which can further simplify the overall structural complexity.

[0073] Optionally, the spraying device includes a spraying part 6. The spraying part 6 is arranged inside the inner tank 4 through the sealing connection mechanism in the above embodiment.

[0074] When the spraying device is in use, it is installed inside the inner tank 4 through the sealing connection structure, so that the cleaning liquid can continuously flow to the spraying part 6 during the rotation of the spraying part 6, and it can also ensure the sealing performance at the connection between the spraying part 6 and the inner tank 4, reducing the possibility of steam and oil fume overflowing.

[0075] Optionally, the spraying part 6 has a liquid storage cavity. The surface of the spraying part 6 has cleaning holes communicating with the liquid storage cavity. In a plane perpendicular to the rotation axis of the spraying part 6, the axial projection of the cleaning holes and the radial projection of the spraying part 6 have an angle greater than zero degrees. The spraying device also includes a liquid injection device 5. The liquid injection device 5 is connected to the sealing connection mechanism to inject cleaning liquid into the liquid storage cavity of the spraying part 6, and uses the thrust generated when the cleaning liquid sprays out from the cleaning holes to push the spraying part 6 to rotate.

[0076] Specifically, the spraying part 6 can be frustum-shaped, and cleaning holes can be provided on both its top wall and side surface. The cleaning holes are arranged to extend obliquely. In this embodiment, the plane perpendicular to the rotation axis of the spraying part 6 is the horizontal plane, that is, in the horizontal plane, the axial projection of the cleaning hole and the radial projection of the spraying part 6 have an angle greater than zero degree. The liquid injection device 5 can include a centrifugal pump 52. The centrifugal pump 52 can pressurize the cleaning liquid and inject it into the liquid storage cavity inside the spraying part 6 through the liquid injection pipe 51. When the high-pressure cleaning liquid sprays out through the cleaning holes, a thrust can be generated to drive the spraying part 6 to rotate. In this way, during the cleaning process, the pressure of the cleaning liquid itself is used to drive the spraying part 6 to rotate, and there is no need to separately set a driving structure to drive the spraying part 6 to rotate, which can not only further simplify the structure, but also reduce energy consumption and improve the energy conservation and environmental protection performance during the cleaning process.

[0077] The cooking device includes an inner container 4 and the spraying device in the above embodiment. The spraying device is arranged in the inner container 4. A drain hole can also be provided at the bottom of the inner container 4, and a filtering device 7 is provided in the drain hole to timely drain the cleaning liquid.

[0078] When the cooking device is in use, since the sealed connection structure can effectively seal the connection between the spraying part 6 and the inner container 4, the possibility of steam and oil fume overflowing to the outside of the inner container 4 can be effectively reduced, the safety of the circuit module of the cooking device can be ensured, and the possibility of damage to the cooking device can be reduced to avoid affecting the normal use of the user.

[0079] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
