Description

Technical Field

[0001] The utility model relates to a household electrical appliance, in particular to a liquid heater. Background Art

[0002] Liquid heaters are commonly used small household appliances for daily household needs and have a wide market. With the improvement of people's living standards, people's demand for liquid heaters is also increasing, and consumers are more willing to choose products with better user experience. However, after long-term use of liquid heaters, scale is easily accumulated in the bottom of the pot. There are two main types of liquid heaters in the prior art. One of them is that one end of the pot lid is connected to the pot body in a hinged manner, and the pot lid is triggered by a button located on the pot lid or on the handle to pop up. The user can open the lid with one hand to collect water. However, when the pot lid of this type of liquid heater is opened, the pot lid will block the pot body, thereby hindering the user from cleaning the scale in the pot body, which is not conducive to cleaning the pot body.

[0003] Another is that the lid and the body can be completely separated. For example, CN209712550U discloses a liquid heating device, including a body and a lid. A detachable inner tank assembly is provided in the body. In order to facilitate the removal and installation of the inner tank assembly, the lid and the body are also detachably connected. Therefore, when cleaning, the inner tank assembly can be removed from the body after the lid is removed. The user can directly clean the inner tank assembly, making the cleaning of the inner tank assembly more convenient. However, the lid needs to be removed during use of the above liquid heater, so the user needs to use two hands to operate, which is inconvenient to use.

[0004] For another example, CN206979347U discloses an electric kettle and a kettle lid, wherein the electric kettle comprises a kettle lid and a kettle body, the kettle lid comprises a lid body and a lid-opening connection part, one end of the lid-opening connection part is detachably connected to one side of the lid body, the other end of the lid-opening connection part is hinged to the kettle body through a rotating shaft, a first fixing part is provided on the lid body, the lid-opening connection part is provided with a second fixing part matched with the first fixing part, the first fixing part and the second fixing part are fixed by a first locking member, the first locking member comprises a first screw hole arranged on the first fixing part, a second screw hole arranged on the second fixing part and a first screw, during use of the electric kettle, the kettle lid can be opened to collect water by pressing a button to rotate the kettle lid as a whole around the axis hole, so that the user can operate it with one hand, and when it is necessary to clean the scale in the kettle body, the first fixing part and the second fixing part can be separated by removing the first screw, so that the kettle lid can be removed for cleaning the kettle body.

[0005] However, when installing and removing the kettle cover, a tool is needed to screw the first screw, which increases the difficulty of installing and removing the kettle cover and easily affects the cleaning efficiency of the kettle body. Utility Model Content

[0006] The utility model aims to provide a liquid heater, which solves the problem of inconvenient installation and disassembly of a kettle body and a kettle cover, and makes the installation and disassembly of the kettle body and the kettle cover faster and more convenient.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a liquid heater, including a kettle body and a kettle lid, the kettle body is provided with a first connecting piece, the first connecting piece is provided with a slot, the kettle lid is provided with a second connecting piece, the second connecting piece is inserted into the slot to realize the detachable connection of the kettle lid to the kettle body, the first connecting piece is hinged to the kettle body and is provided with an elastic piece that keeps the kettle lid opening, the first connecting piece is provided with an elastic protrusion extending into the slot, the second connecting piece is provided with a limiting groove, the elastic protrusion and the limiting groove cooperate to increase the resistance of the second connecting piece to separate from the first connecting piece.

[0008] After adopting the above technical solution, the utility model has the following advantages:

[0009] The kettle body described in the utility model is provided with a first connecting piece, and the kettle lid is provided with a second connecting piece. The kettle lid and the kettle body are detachably connected through the cooperation of the first connecting piece and the second connecting piece. The first connecting piece is provided with an elastic piece, and the elastic piece can make the kettle lid bounce up and then open the lid to collect water, so that the user can perform one-handed operation, which is beneficial to improving the user experience. When the kettle lid and / or the kettle body needs to be cleaned, the second connecting piece is detached from the slot of the first connecting piece to achieve complete separation of the kettle lid and the kettle body. The kettle lid can be cleaned separately, and when cleaning the kettle body, the kettle lid can be prevented from blocking the kettle body, making the cleaning of the kettle body simpler and more convenient, and can also reduce the residual amount of scale in the kettle body, which is beneficial to improving the cleanliness of the kettle body.

[0010] In addition, the first connecting member is provided with an elastic protrusion, and the second connecting member is provided with a limiting groove. After the second connecting member is inserted into the slot, the elastic protrusion is embedded in the limiting groove, thereby increasing the resistance of the second connecting member to be separated from the first connecting member, reducing the possibility of the kettle cover being separated from the kettle body at will, and improving the connection stability between the kettle cover and the kettle body. When the kettle cover needs to be removed, only a large external force is required to make the elastic protrusion separate from the limiting groove, thereby realizing the separation of the kettle cover from the kettle body. Similarly, when installing the kettle cover, the second connecting member is inserted into the slot so that the elastic protrusion is embedded in the limiting groove, so that the user can feel that the kettle cover and the kettle body are connected in place, and the installation of the kettle cover is completed. The installation and disassembly of the kettle cover are relatively simple and convenient, without the use of additional tools, which is conducive to improving the installation and disassembly efficiency of the kettle cover, and can also speed up the cleaning speed of the kettle body.

[0011] Furthermore, the elastic protrusion is arranged on the elastic member, and the first connecting member is provided with a through hole for the elastic protrusion to extend from the outside to the inside into the slot. By adopting the above technical solution, the elastic protrusion is arranged on the elastic member, which can save the need for fixing the elastic protrusion, making the installation of the elastic protrusion simpler and more convenient, and can also improve the installation stability of the elastic protrusion; in addition, the elastic protrusion extends into the slot through the through hole, which can further reduce the installation difficulty of the elastic protrusion, and is also conducive to limiting the elastic protrusion through the through hole, thereby improving the installation limiting effect of the elastic member.

[0012] Furthermore, the elastic member includes an elastic part that provides torque, a transmission part that abuts against the first connecting member to transmit torque to rotate the first connecting member, one end of the elastic part is positioned on the kettle body, and the other end is connected to the transmission part, and the elastic protrusion is arranged on the transmission part. With the above technical solution, the elastic part provides torque for the rotation of the kettle lid, thereby realizing the automatic rotation of the kettle lid, making it more convenient and labor-saving to open the lid; in addition, the transmission part abuts against the first connecting member to facilitate the torque transmission of the elastic member, ensuring that the elastic protrusion remains inserted into the slot through the through hole and abuts against the limiting groove of the second connecting member, and at the same time, the positioning stability of the elastic member can also be improved.

[0013] Furthermore, the elastic protrusion is formed by the metal body bending and extending along the first plane, and the first plane is parallel to the plug-in direction of the second connector and the first connector; or, the elastic protrusion is formed by the metal body bending and extending along the second plane, and the second plane is perpendicular to the plug-in direction of the second connector and the first connector. With the above-mentioned technical solution, the elastic protrusion is bent and extended along the first plane, and inclined surfaces are formed on both sides of the elastic protrusion, which can guide the second connector to pass over the elastic protrusion, thereby making it easier to insert the second connector into the slot or to disengage from the slot, and facilitating the installation and removal of the pot cover; in addition, when the elastic protrusion is bent and extended along the second plane, the elastic protrusion cooperates with the limiting groove to effectively increase the resistance of the second connector to disengage from the first connector, improve the connection stability of the second connector and the first connector, reduce the possibility of the second connector arbitrarily disengaging from the first connector, and make the connection between the pot cover and the pot body more firm and reliable.

[0014] Furthermore, the diameter of the metal body is D, and the height of the elastic protrusion extending into the slot is H≤D; and / or, the front end of the second connecting member is provided with a guide surface facing the elastic protrusion. By adopting the above-mentioned technical solution, the height of the elastic protrusion extending into the slot is less than the diameter of the metal body, which can effectively avoid the elastic protrusion from hindering the insertion of the second connecting member, so that the second connecting member can pass over the elastic protrusion so that the elastic protrusion can be inserted into the limiting groove; and when H>D, the height of the elastic protrusion in the slot is relatively high. After the second connecting member is inserted into the slot, the elastic protrusion will form a blockage for the second connecting member, so that the second connecting member cannot be fully inserted into the slot, thereby causing the second connecting member to be unable to be positioned, affecting the connection between the pot lid and the pot body; in addition, the guide surface can guide the second connecting member to pass over the elastic protrusion, reduce the possibility of the second connecting member and the elastic protrusion abutting against each other, and make the insertion of the second connecting member more labor-saving.

[0015] Furthermore, the through hole is provided on the bottom surface of the first connecting member, and the transmission part is bent and extended on the bottom surface of the first connecting member and abuts against the bottom surface of the first connecting member to transmit the torque for rotating the first connecting member, and limit the height of the elastic protrusion extending into the slot. With the above-mentioned technical solution, the transmission part is bent and extended on the bottom surface of the first connecting member, which can increase the contact area between the transmission part and the first connecting member, reduce the possibility of the transmission part slipping, make the fixing of the transmission part more stable, and also can stably transmit torque for the first connecting member; in addition, the bending and extension of the transmission part can provide enough space for the setting of the elastic protrusion, making the setting of the elastic protrusion more convenient, and at the same time, the transmission part abuts against the bottom surface of the first connecting member, which can effectively limit the height of the elastic protrusion extending into the slot, and reduce the possibility of the elastic protrusion forming an obstacle to the second connecting member.

[0016] Furthermore, a groove is provided on the side of the first connecting member, and the transmission part extends along the groove and transmits the torque for rotating the first connecting member through the groove. With the above technical solution, the groove can position the transmission part, reduce the possibility of the transmission part slipping, and make the torque transmission more stable and reliable.

[0017] Furthermore, the through hole is arranged in the embedding groove. With the above technical solution, the elastic protrusion extends into the through hole to form a positioning fit, and the matching relationship between the elastic protrusion and the through hole can enhance the reliability of torque transmission between the transmission part and the first connecting member.

[0018] Furthermore, the elastic part has two and is located on both sides of the first connecting member, and the transmission part is connected between the two elastic parts; and / or, the first connecting member is hinged to the kettle body through a rotating shaft, and the elastic part is a torsion spring structure formed by the spiral extension of a metal body, and the elastic part is sleeved on the rotating shaft. The above technical solution can increase the stability of the elastic part after installation, and it is not easy to separate from the first connecting member, thereby increasing the reliability of long-term use, and can evenly distribute the torque to both sides of the first connecting member, so that the rotation of the first connecting member is smoother and not easy to deflect and get stuck; the elastic part is sleeved on the rotating shaft to increase the reliability of long-term use.

[0019] Furthermore, the first connecting member is provided with an elastic arm, the elastic protrusion is provided at the free end of the elastic arm, and the elastic arm is located at the bottom or side of the slot. The above-mentioned technical solution is adopted, the elastic protrusion is provided at the free end of the elastic arm, and when the second connecting member is inserted into the slot, the elastic arm undergoes elastic deformation to allow the second connecting member to pass over the elastic protrusion, making the installation of the second connecting member more labor-saving; in addition, the elastic protrusion is located at the free end of the elastic arm, so that the elastic protrusion has a larger deformation range, avoiding the elastic protrusion from hindering the insertion of the second connecting member.

[0041] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0042] like Figure 1 As shown, the utility model provides a liquid heater, including a kettle body 1, a kettle cover 2 and a base 3, the kettle body 1 is provided with a first connecting member 14, the first connecting member 14 is provided with a slot 141, the kettle cover 2 includes an inner cover 22 and an outer cover 21 spliced ​​to each other, and the kettle cover 2 is provided with a second connecting member 23, the second connecting member 23 is inserted into the slot 141 to realize that the kettle cover 2 can be detachably connected to the kettle body 1, the first connecting member 14 is hinged to the kettle body 1 and is provided with an elastic member 4 that keeps the kettle cover 2 from opening, and the elastic member 4 can make the kettle cover 2 bounce up and The lid can be opened to collect water, so that the user can perform one-handed operation, which is beneficial to improving the user experience. When the kettle lid 2 and / or the kettle body 1 need to be cleaned, the second connecting member 23 is disengaged from the slot 141 of the first connecting member 14 to achieve complete separation of the kettle lid 2 and the kettle body 1. The kettle lid 2 can be cleaned separately, and when cleaning the kettle body 1, the kettle lid 2 can be prevented from blocking the kettle body 1, making the cleaning of the kettle body 1 simpler and more convenient, and can also reduce the amount of residual scale in the kettle body 1, which is beneficial to improving the cleanliness of the kettle body 1.

[0043] In order to facilitate the installation and disassembly of the first connecting member 14 and the second connecting member 23, in this embodiment, the first connecting member 14 is provided with an elastic protrusion 5 extending into the slot 141, and the second connecting member 23 is provided with a limiting groove 231. The elastic protrusion 5 cooperates with the limiting groove 231 to increase the resistance of the second connecting member 23 from being separated from the first connecting member 14. After the second connecting member 23 is inserted into the slot 141, the elastic protrusion 5 is embedded in the limiting groove 231, thereby increasing the resistance of the second connecting member 23 from being separated from the first connecting member 14, reducing the possibility of the pot cover 2 being separated from the pot body 1 at will, and improving the pot cover 2 and the pot body 1. The connection is stable, and when the pot cover 2 needs to be removed, only a large external force is needed to make the elastic protrusion 5 disengage from the limiting groove 231, thereby realizing the separation of the pot cover 2 and the pot body 1. Similarly, when installing the pot cover 2, the second connecting piece 23 is inserted into the slot 141 to make the elastic protrusion 5 embed into the limiting groove 231, so that the user can feel that the pot cover 2 and the pot body 1 are connected in place, and the installation of the pot cover 2 is completed. The installation and removal of the pot cover 2 are relatively simple and convenient, without the use of additional tools, which is conducive to improving the installation and removal efficiency of the pot cover 2, and also can speed up the cleaning speed of the pot body 1.

[0044] like Figure 1 and Figure 2 As shown, the kettle body 1 in this embodiment includes an inner tank for holding liquid, a heater 13 installed on the outer side of the bottom of the inner tank, and an upper connector 11 at the bottom of the kettle body 1, the upper connector 11 is electrically connected to the heater 13, and the heater 13 is electrically connected to a control switch 12, the base 3 is provided with a lower connector 31 matching the upper connector 11 and a power plug 32 electrically connected to the lower connector 31, the upper connector 11 and the lower connector 31 are plugged and electrically coupled to make the heater 13 and the power plug 32 electrically conductive.

[0045] like Figures 1 to 3 As shown, the kettle body 1 in this embodiment includes a handle 16, and the first connecting member 14 is arranged inside the top of the handle 16. The handle 16 is provided with a button 117 for controlling the opening of the kettle lid 2 and a mounting hole 161 for installing the button 117. The button 117 is hinged to the handle 16 and is provided with a compression spring 18. The compression spring 18 acts on the button 117 and makes the button 117 maintain a movement trend of partially exposing the mounting hole 161. A convex point 171 for positioning the first connecting member 14 is provided on the side of the button 117 close to the first connecting member 14. The first connecting member 14 is provided with a boss 145. When the kettle lid 2 and the kettle body 1 are closed, the convex point 171 abuts against the bottom of the boss 145 and thus overcomes the elastic force of the elastic member 4 to keep the kettle lid 2 closed. When the kettle lid 2 needs to be opened, the convex point 171 is disengaged from the boss 145 by pressing the button 117, and the first connecting member 14 rotates under the action of the elastic member 4 to rotate and open the kettle lid 2.

[0046] In this embodiment, after the first connecting member 14 is arranged on the handle 16, the thickness of the kettle body 1 can be effectively reduced, making the manufacture of the kettle body 1 simpler, and at the same time, the kettle body 1 can have a larger opening after the lid is opened, further reducing the obstruction of the kettle body 1 by the lid 2; in addition, in order to facilitate the user to press the button 117, the mounting hole 161 in this embodiment is arranged at the bend at the top of the handle 16, and the end of the button 117 close to the kettle body 1 is provided with a hinge shaft 172 hinged to the handle 16, and the compression spring 18 acts on the other end of the button 117, so that the pressing point of the button 117 is closer to the position of the user's thumb, so that the user can perform one-handed operation, which is conducive to improving the user experience.

[0047] It should be noted that, in other embodiments, the button 117 can also be arranged on the pot lid 2, and a buckle is provided on the side of the pot lid 2 away from the second connecting member 23, and the button 117 is transmission-connected with the buckle, and a slot cooperating with the buckle is provided on the inner side of the top of the kettle body 1. When the pot lid 2 is closed, the buckle cooperates with the slot to restrict the pot lid 2 from separating from the kettle body 1, thereby achieving the closure of the pot lid 2. When the pot lid 2 needs to be opened, the buckle is controlled to separate from the slot by pressing the button 117, and the pot lid 2 can be opened under the action of the elastic member 4 to complete the opening of the lid; the buckle and the second connecting member 23 are respectively located on both sides of the pot lid 2, so that the buckle and the second connecting member 23 are kept at a relatively far distance, which can reduce the force on the buckle and reduce the possibility of the buckle breaking.

[0048] like Figures 3 to 5 As shown, in this embodiment, the first connecting member 14 is hinged to the kettle body 1 through the rotating shaft 15, and the elastic member 4 includes an elastic part 41 that provides torque, and a transmission part 42 that abuts against the first connecting member 14 to transmit torque to rotate the first connecting member 14. One end of the elastic part 41 is positioned on the kettle body 1, and the other end is connected to the transmission part 42, wherein the elastic part 41 has two and is located on both sides of the first connecting member 14, and the transmission part 42 is connected between the two elastic parts 41, and the elastic protrusion 5 is provided on the transmission part 42, and the elastic part 41 is The torsion spring structure is formed by the spiral extension of the slender metal body, and the elastic part 41 is mounted on the rotating shaft 15. The elastic part 41 provides torque for the rotation of the pot cover 2, thereby realizing the automatic rotation of the pot cover 2, making it more convenient and labor-saving to open the cover; in addition, the transmission part 42 abuts against the first connecting member 14 to facilitate the torque transmission of the elastic member 4, ensuring that the elastic protrusion 5 remains through the through hole 142 to extend into the slot 141 and abuts against the limiting groove 231 of the second connecting member 23, and at the same time, the positioning stability of the elastic member 4 can also be improved.

[0049] In addition, the elastic part 41 has two parts and is located on both sides of the first connecting member 14, which can increase the stability of the elastic member 4 after installation, and is not easy to be separated from the first connecting member 14, thereby increasing the reliability of long-term use, and can evenly distribute the torque to both sides of the first connecting member 14, so that the rotation of the first connecting member 14 is smoother and not easy to deflect and get stuck; the elastic part 41 is mounted on the rotating shaft 15, which can also increase the reliability of long-term use.

[0050] like Figure 4 As shown, in this embodiment, a groove 143 is provided on the side of the first connecting member 14, and the transmission part 42 extends along the groove 143 and transmits the torque for rotating the first connecting member 14 through the groove 143. The groove 143 can position the transmission part 42, reduce the possibility of slipping of the transmission part 42, and make the torque transmission more stable and reliable. In addition, the transmission part 42 is bent and extended on the bottom surface of the first connecting member 14 and abuts against the bottom surface of the first connecting member 14, which can effectively increase the contact area between the transmission part 42 and the first connecting member 14, reduce the possibility of slipping of the transmission part 42, make the fixation of the transmission part 42 more stable, and also can stably transmit torque for the first connecting member 14; in addition, the bending and extension of the transmission part 42 can provide sufficient space for the setting of the elastic protrusion 5, making the setting of the elastic protrusion 5 more convenient.

[0051] like Figure 6 As shown, in order to further improve the stability of torque transmission by the transmission part 42, in other embodiments, the length of the transmission part 42 bending and extending on the bottom surface of the first connecting member 14 can be increased, further increasing the contact area between the transmission part 42 and the first connecting member 14, and reducing the possibility of slipping of the transmission part 42, which is beneficial to improving the positioning stability of the transmission part 42 and making the torque transmission more stable.

[0052] like Figure 3 and Figure 4 As shown, the elastic protrusion 5 described in this embodiment is arranged on the elastic member 4, and the first connecting member 14 is provided with a through hole 142 for the elastic protrusion 5 to extend from the outside to the inside into the slot 141, and the through hole 142 is arranged on the bottom surface of the first connecting member 14. The elastic protrusion 5 is arranged on the elastic member 4, which can omit the fixation of the elastic protrusion 5, make the installation of the elastic protrusion 5 simpler and more convenient, and can also improve the installation stability of the elastic protrusion 5; in addition, the elastic protrusion 5 extends into the slot 141 through the through hole 142, which can further reduce the installation difficulty of the elastic protrusion 5, and is also conducive to the formation of a limit for the elastic protrusion 5 through the through hole 142, thereby improving the installation limit effect of the elastic member 4; secondly, since the transmission part 42 is simultaneously abutted against the bottom surface of the first connecting member 14, the elastic protrusion 5 extends from the bottom surface of the first connecting member 14 from the outside to the inside into the slot 141, so the transmission part 42 can effectively limit the height of the elastic protrusion 5 extending into the slot 141, thereby reducing the possibility of the elastic protrusion 5 forming an obstacle to the second connecting member 23.

[0053] Of course, it is understandable that in other embodiments, the through hole 142 can also be arranged in the embedding groove 143, the elastic protrusion 5 can also be arranged on the transmission part 42 located in the embedding groove 143, and the corresponding limiting groove 231 can also be arranged on the side of the second connecting member 23, so that after the second connecting member 23 is inserted into the slot 141, the elastic protrusion 5 can be embedded in the limiting groove 231, thereby increasing the resistance of the second connecting member 23 to separate from the first connecting member 14; secondly, the elastic protrusion 5 extends into the through hole 142 to form a positioning fit, and the matching relationship between the elastic protrusion 5 and the through hole 142 can enhance the reliability of torque transmission between the transmission part 42 and the first connecting member 14.

[0054] In addition, in order to increase the positioning stability of the second connecting member 23, through holes 142 can be set in the two embedding grooves 143 on the first connecting member 14, and the transmission part 42 can also be provided with two elastic protrusions 5 corresponding to the two through holes 142 respectively. Similarly, the second connecting member 23 can also be provided with two limiting grooves 231. Through the cooperation of the two elastic protrusions 5 and the limiting grooves 231, resistance is formed on both sides of the second connecting member 23 respectively, so that the force on the second connecting member 23 is more balanced, the possibility of the second connecting member 23 detaching from the slot 141 is reduced, and the connection stability between the second connecting member 23 and the first connecting member 14 is improved.

[0055] like Figure 3 and Figure 5 As shown, the elastic protrusion 5 in this embodiment is formed by a slender metal body bending and extending along a first plane, the first plane is parallel to the plug-in direction of the second connecting member 23 and the first connecting member 14, and the elastic protrusion 5 is a triangle as a whole. The tip in the middle of the elastic protrusion 5 is positioned and matched with the limiting groove 231, and inclined surfaces are formed on both sides of the tip. The two inclined surfaces can guide the second connecting member 23 to pass over the elastic protrusion 5, thereby making it easier to insert the second connecting member 23 into the slot 141 or detach from the slot 141, thereby facilitating the installation and disassembly of the pot cover 2.

[0056] In order to further facilitate the installation and disassembly of the second connecting member 23, in this embodiment, the front end of the second connecting member 23 is provided with a guide surface 232 facing the elastic protrusion 5, and the guide surface 232 can guide the second connecting member 23 to pass over the elastic protrusion 5, thereby reducing the possibility of the second connecting member 23 and the elastic protrusion 5 to collide with each other, thereby making the insertion of the second connecting member 23 more labor-saving.

[0057] like Figures 7 to 10As shown, in one embodiment, the elastic protrusion 5 is formed by a slender metal body bending and extending along a second plane, and the second plane is perpendicular to the plug-in direction of the second connecting member 23 and the first connecting member 14. When the elastic protrusion 5 is bent and extended along the second plane, the elastic protrusion 5 cooperates with the limiting groove 231 to effectively increase the resistance of the second connecting member 23 from being separated from the first connecting member 14, improve the connection stability between the second connecting member 23 and the first connecting member 14, reduce the possibility of the second connecting member 23 being arbitrarily separated from the first connecting member 14, and make the connection between the pot cover 2 and the pot body 1 more firm and reliable.

[0058] like Fig. 9 As shown, the diameter of the slender metal body in this embodiment is D, and the height of the elastic protrusion 5 extending into the slot 141 is H≤D, that is, the height of the elastic protrusion 5 extending into the slot 141 is less than the diameter of the metal body, which can effectively avoid the elastic protrusion 5 from hindering the insertion of the second connecting member 23, so that the second connecting member 23 can pass over the elastic protrusion 5, so that the elastic protrusion 5 can be inserted into the limiting groove 231; and when H>D, the height of the elastic protrusion 5 in the slot 141 is higher. After the second connecting member 23 is inserted into the slot 141, the elastic protrusion 5 will form a blockage for the second connecting member 23, so that the second connecting member 23 cannot be fully inserted into the slot 141, thereby causing the second connecting member 23 to be unable to be positioned, thereby affecting the connection between the pot cover 2 and the pot body 1.

[0059] like Figures 11 to 13 As shown, in another embodiment, the first connecting member 14 is provided with an elastic arm 144, and the elastic arm 144 is located on the bottom surface of the slot 141, and the elastic protrusion 5 is provided at the free end of the elastic arm 144. The elastic protrusion 5 is set at the free end of the elastic arm 144. When the second connecting member 23 is inserted into the slot 141, the elastic arm 144 is elastically deformed to allow the second connecting member 23 to pass over the elastic protrusion 5, making the installation of the second connecting member 23 more labor-saving; in addition, the elastic protrusion 5 is at the free end of the elastic arm 144, so that the elastic protrusion 5 has a larger deformation range, thereby avoiding the elastic protrusion 5 from hindering the insertion of the second connecting member 23.

[0060] like Fig.14 and Fig.15As shown, it can be understood that in other embodiments, the elastic arm 144 can also be located on the side of the slot 141, and the corresponding limiting groove 231 can also be arranged on the side of the second connecting member 23, so that after the second connecting member 23 is inserted into the slot 141, the elastic protrusion 5 can be embedded in the limiting groove 231, thereby increasing the resistance of the second connecting member 23 to separate from the first connecting member 14; in addition, in order to increase the positioning stability of the second connecting member 23, two elastic arms 144 can be provided on the first connecting member 14 and are respectively located on both sides of the slot 141, and correspondingly, limiting grooves 231 are respectively provided on both sides of the second connecting member 23. Through the cooperation of the two elastic protrusions 5 and the limiting grooves 231, resistance is respectively formed on both sides of the second connecting member 23, so that the force on the second connecting member 23 is more balanced, the possibility of the second connecting member 23 separating from the slot 141 is reduced, and the connection stability between the second connecting member 23 and the first connecting member 14 is improved.

[0061] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
