[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0028] This embodiment mainly describes a push-type heat-insulating teapot that is easy to clean, as follows:

[0029] like Figures 1 to 7As shown, the push-type heat-insulating teapot that is easy to clean includes a pot body 1, a tea brewing cup 2 arranged at the opening of the pot body 1 and extending into the pot body 1, and a pot lid 3 covering the tea brewing cup 2. The tea brewing cup 2 is mainly used for brewing tea, and the pot body 1 is mainly used for holding tea. When the tea leaves in the tea brewing cup 2 are brewed, the tea in the tea brewing cup 2 flows into the pot body 1 and is separated from the tea leaves in the tea brewing cup 2, so as to avoid affecting the taste of the tea due to long-term soaking of the tea leaves. The opening of the pot body 1 is provided with a spout 14 extending outward from the pot body 1, and the tea leaves in the pot body 1 can be poured out from the spout 14. The bottom of the tea brewing cup 2 is provided with several filtering holes 21 which are connected to the pot body 1. The tea in the tea brewing cup 2 can flow into the pot body 1 through the filtering holes 21. A water sealing component 4 is provided at the bottom of the tea brewing cup 2. The filtering holes 21 can be opened / closed by controlling the water sealing component 4. The water sealing component 4 has a connecting part which passes through the bottom of the filtering cup and extends into the tea brewing cup 2 and is slidably connected to the tea brewing cup 2. A detachable limiting cap 43 is provided on the connecting part. A sliding sleeve on the connecting part is provided with a reset spring 5 whose two ends are respectively connected to the tea brewing cup 2 and the limiting cap 43. A resilient pressing part 6 is provided on the pot cover 3 which pushes the connecting part to slide when pressed. There is a distance between the lower end of the water sealing component 4 and the bottom wall of the pot body 1 to facilitate the up and down movement of the water sealing component 4. When the resilient pressing member 6 is forced to slide downward, the resilient pressing member 6 slides downward, pushing the connecting portion to slide downward, thereby driving the water sealing assembly 4 to slide downward and separate from the bottom of the tea brewing cup 2, at which time the filter hole 21 is opened; when the resilient pressing member 6 loses its downward pressing force, the resilient pressing member 6 returns to its initial position, and the water sealing assembly 4 slides upward under the action of the return spring 5 to close the filter hole 21. When making tea, tea leaves and tea are placed in the tea brewing cup 2 for soaking. When the tea leaves are brewed, the resilient pressing member 6 is pressed to push the water sealing assembly 4 to slide downward and open the filter hole 21. The tea in the tea brewing cup 2 flows into the pot body 1 through the filter hole 21 to separate the tea leaves and the tea water. When the tea leaves and the tea water are separated, the resilient pressing member 6 is stopped being pressed. The water sealing assembly 4 is no longer under the pressure of the resilient pressing member 6 and slides upward under the action of the return spring 5 to close the filter hole 21. The detachable design of the limiting cap 43 in this solution facilitates the disassembly of the tea brewing cup 2 and the water sealing component 4. When the limiting cap 43 is disassembled, the connecting portion can be pulled out from the tea brewing cup 2, making it convenient to clean the water sealing component 4 and the tea brewing cup 2. This ensures that the tea brewing cup 2 can be cleaned and improves the taste of the tea.

[0030] like Figure 4 、 Figure 5 and Figure 7As shown, the water sealing assembly 4 includes a sealing cover 41, a connecting post 42, and a limiting cap 43. The connecting post 42 is fixed to the sealing cover 41 and is preferably integrally formed with the sealing cover 41. The tea brewing cup 2 has a connecting tube 22 extending from the bottom through the bottom wall of the tea brewing cup 2 into the tea brewing cup 2. The connecting tube 22 forms a channel for the connecting post 42 to pass through. The connecting post 42 passes through the connecting tube 22 and extends into the tea brewing cup 2 to form the above-mentioned connection portion. The limiting cap 43 is detachably connected to the connecting post 42. The return spring 5 is mounted on the connecting post 42. The limiting cap 43 has an internal mounting chamber 44 for mounting the return spring 5. The reset spring 5 is arranged in the mounting chamber 44 to protect the reset spring 5 and prevent tea leaves from entering the reset spring 5 during the tea brewing process, causing the reset spring 5 to fail.

[0031] Specifically, a first step 23 is provided on the connecting tube 22, one end of the return spring 5 rests on the first step 23, and the other end rests on the bottom wall of the installation chamber 44. When the resilient pressing member 6 presses the connecting column 42 downward so that the connecting column 42 drives the blocking cover 41 to slide downward, the limiting cover slides downward with the connecting column 42. At this time, the return spring 5 is squeezed by the bottom wall of the limiting cover installation chamber 44 and the first step 23 and deformed. When the resilient pressing member 6 returns to its initial state, the elastic force of the return spring 5 pushes the limiting cover to drive the blocking cover 41 to slide upward to close and seal the filter hole 21.

[0032] Specifically, a second step 24 is provided on the connecting tube 22, located below the first step 23. The second step 24 is used to limit the downward displacement of the blocking cover 41. When the resilient pressing member 6 drives the connecting post 42 to slide downward until the lower end of the limiting cap 43 abuts the second step 24, the filter hole 21 is opened. The provision of the second step 24 prevents the connecting post 42 from moving downward excessively, which could cause the lower end of the limiting cap to repeatedly squeeze the tea leaves, causing the tea leaves to break and enter the teapot body 1, affecting the taste of the tea.

[0033] like Figure 4 As shown, in order to prevent the tea in the pot body 1 from seeping into the tea brewing cup 2 through the gap between the sealing cover 41 and the tea brewing cup 2 and soaking the tea leaves, thereby affecting the taste of the tea, a protruding annular platform 411 is provided on the outer wall of the sealing cover 41 along the circumference, and a first sealing ring 412 is sleeved on the annular platform 411. A supporting ring 25 cooperating with the first sealing ring 412 is provided at the bottom end of the tea brewing cup 2. When the resilient pressing member 6 loses its force, the supporting ring 25 abuts against the first sealing ring 412. Through the cooperation of the first sealing ring 412 and the supporting ring 25, the bottom of the tea brewing cup 2 is sealed.

[0034] Specifically, the limiting cap 43 can be detachably connected to the connecting column 42 by threaded connection or clamping. This patent realizes detachability by clamping, such as Figure 5The cam 422 is engaged with the cam 423 and the cam 424 is engaged with the cam 425. The cam 422 is engaged with the cam 423 and the cam 424 is engaged with the cam 425. The vertical sliding groove 422 and the limiter mentioned above have a guiding function, which can make the limiter cover slide toward the preset track during installation and removal.

[0035] Specifically, in order to improve the stability of the limiting cover, there are two groups of vertical slide grooves 422 and limiting grooves 421, which are evenly distributed along the circumference of the outer wall of the connecting column 42. One vertical slide groove 422 and one limiting groove 421 form a group. There are two groups of limiting protrusions 432, which correspond one-to-one to each group of vertical slide grooves 422 and limiting grooves 421.

[0036] like Figure 4 and Figure 7 As shown, the resilient pressing member 6 includes a button 61, a pushing column 62 fixedly connected to the button 61 and a compression spring 63 sleeved on the pushing column 62. The pot cover 3 includes a bottom cover 31 and a top cover 32 clamped with the bottom cover 31. The top cover 32 is provided with a through hole 321 which coincides with the center of the connecting tube 22. The bottom cover 31 is provided with a connecting hole 311 which coincides with the center of the through hole 321. The pushing column 62 passes through the through hole 321 and the connecting hole 311 in sequence and extends into the pot body 1 to abut against the connecting column 42. The lower end of the button 61 has an outer edge 611 extending in the circumferential direction. The outer edge 611 abuts against the edge of the top cover 32 close to the through hole 321. The setting of the outer edge 611 limits the button 61 so that the button 61 slides between the through hole 321 and the connecting hole 311. One end of the compression spring 63 abuts against the top surface of the lower cover, and the other end abuts against the bottom surface of the button 61.

[0037] Specifically, the diameter of the connecting hole 311 matches the diameter of the push post 62. An annular groove 621 is provided on the outer wall of the lower portion of the push post 62. A second sealing ring 622 is provided in the annular groove 621. The top surface of the second sealing ring 622 abuts against the edge of the lower cover near the connecting hole 311. The provision of the second sealing ring 622 prevents heat from the teacup 2 from escaping through the gap between the push post 62 and the button 61 during tea brewing, thereby affecting the quality of the tea.

[0038] like Figure 1 、 Figure 3 and Figure 7 As shown, the kettle body 1 includes an upper kettle body 11, a lower kettle body 12 and a sleeve 13 arranged between the upper kettle body 11 and the lower kettle body 12. The sleeve 13 is clamped with the lower kettle body 12, and the upper kettle body 11 is clamped with the sleeve 13. A first annular sealing ring 8 is provided between the lower kettle body 12 and the sleeve 13, and a second annular sealing ring 9 is provided between the upper kettle body 11 and the sleeve 13. A handle 7 is provided on the sleeve 13. The tea brewing cup 2 is located at the opening of the upper kettle body 11 and extends toward the lower kettle body 12. In order to facilitate observation of the tea brewing situation in the tea brewing cup 2, the upper kettle body 11 is made of transparent glass material. In order to improve the heat preservation of the teapot, the lower kettle body 12 is a vacuumed double-layer stainless steel structure.

[0039] In order to further improve the heat preservation effect of the teapot, a third sealing ring 26 is provided on the upper side wall of the tea cup 2 and is in contact with the inner wall of the upper pot body 11. A fourth sealing ring 312 is provided on the outer side wall of the bottom cover 31 and is in contact with the side wall of the tea cup 2.
