Description

Technical Field

[0001] The utility model belongs to the field of drinking water equipment, and in particular relates to a thermos pot. Background Art

[0002] At present, most of the existing thermos kettles on the market use a button-pressing method to release water. The button drives the valve cover of the water outlet valve to move downward to open the water outlet channel on the kettle cover, so that the water in the kettle body flows out through the water outlet channel. However, when the water temperature in the thermos kettle changes, the valve cover and accessories related to the valve cover are prone to deformation due to thermal expansion and contraction. In some cases, this deformation will cause the valve cover to move downward, so that the valve cover cannot be tightly covered with the entrance of the water outlet channel, resulting in the water outlet channel being opened and causing water leakage.

[0015] The beneficial effects of the utility model are:

[0016] A thermos pot, comprising a pot cover, the pot cover comprising a cover body provided with a water outlet channel and a water outlet valve installed on the cover body, the water outlet valve comprising a valve cover, the valve cover being arranged at the bottom of the pot cover for opening and closing the water outlet channel, a first sealing ring being arranged at the bottom of the cover body, the first sealing ring comprising a connecting portion surrounding and connected to the inlet wall of the water outlet channel and a sealing lip being arranged at the bottom of the connecting portion and surrounding the water outlet channel; wherein the sealing lip extends a predetermined length along the opening direction of the valve cover, the predetermined length is less than the maximum movable distance of the valve cover along the opening direction, and the valve cover can seal and cover the inlet of the water outlet channel by squeezing the sealing lip. The technical solution has the following technical effects:

[0017] The utility model provides a first sealing ring with a sealing lip at the entrance of the water inlet channel, so that when the valve cover closes the water outlet channel, the valve cover and the sealing lip abut against each other and squeeze the sealing lip against the cover body, and the sealing lip is deformed toward one side of the cover body under the squeezing of the valve cover, and the deformed sealing lip is tightly fitted on the top surface of the valve cover under the action of elastic force, so as to achieve the sealing covering of the valve cover on the entrance of the water outlet channel, so that the valve cover has a better closing effect on the entrance of the water outlet channel; when the valve cover moves downward slightly due to the virtual position problem of the key or other reasons, the sealing lip can be reset toward the valve cover under the action of elastic force, and fills the gap generated between the valve cover and the entrance wall of the water outlet channel when the valve cover moves downward through its own deformation, so as to ensure that the sealing lip is always tightly fitted with the top surface of the valve cover, and then ensure that the valve cover is sealed and covered on the entrance of the water outlet channel, so as to prevent the entrance of the water outlet channel from being freely opened, causing the water in the thermos pot to leak out through the water outlet channel, and avoid scalding of the user by the leaked hot water, so as to make it safer to use. Because the extended length of the sealing lip is smaller than the maximum movable distance of the valve cover along the opening direction, when the user needs to pour water, he only needs to control the downward movement distance of the valve cover to be greater than the extended length of the sealing lip, so that a gap connecting the inside of the thermos pot and the water outlet channel can be formed between the sealing lip and the valve cover, so that the user can quickly pour out the water in the thermos pot through the water outlet channel, thereby improving the user experience.

[0018] The inner diameter of the sealing lip gradually increases from top to bottom, so that the sealing lip is in a trumpet shape with a small top and a large bottom. In the process of the valve cover gradually approaching the water outlet channel to close the entrance of the water outlet channel, the top surface of the valve cover directly abuts against the inner side wall of the sealing lip, and pushes the sealing lip to deform toward the outer peripheral side, so that the contact area between the top surface of the valve cover and the sealing lip gradually increases, greatly enhancing the sealing effect between the sealing lip and the valve cover, ensuring that the valve cover tightly covers the entrance of the water outlet channel, and having a good leak-proof effect.

[0019] The sealing lip includes an inner sealing lip and an outer sealing lip which are arranged concentrically. The outer sealing lip is arranged on the outer peripheral side of the inner sealing lip and forms a sealing gap with the inner sealing lip. When the valve cover gradually approaches the water outlet channel to close the entrance of the water outlet channel, the top surface of the valve cover contacts the inner sealing lip and the outer sealing lip at the same time and pushes them to deform. The sealing gap can provide space for deformation so that the deformed inner sealing lip and the outer sealing lip can fit tightly on the top surface of the valve cover under the action of elastic force. The double-layer sealing setting can complement each other, so that when one of the inner sealing lip and the outer sealing lip is damaged, the first sealing ring can still fit tightly with the valve cover.

[0020] The connecting part is a ring body arranged around the water outlet channel, and the ring body abuts against the bottom surface of the inlet wall of the water outlet channel. By abutting the ring body against the bottom surface of the inlet wall of the water outlet channel, the inlet wall of the water outlet channel and the first sealing ring can be sealed to prevent the water in the thermos pot from entering the water outlet channel through the gap between the first sealing ring and the inlet wall of the water outlet channel and causing water leakage.

[0021] The thermos pot also includes a pot body, a pot lid is covered on the pot body, a second sealing ring is also provided on the pot lid and is located above the first sealing ring, the pot lid and the pot body are sealed by the second sealing ring, and the first sealing ring and the second sealing ring are an integrated structure. By arranging the first sealing ring and the second sealing ring as one, during installation, the first sealing ring is installed on the lid body, and the first sealing ring and the second sealing ring can be installed and positioned on the lid body at the same time, and the first sealing ring can be connected to the lid body through the second sealing ring, and there is no need to fix the first sealing ring and the lid body, which simplifies the assembly steps, reduces the assembly difficulty, and improves the assembly efficiency.

[0022] The pot cover has a cylinder body surrounding the entrance of the water outlet channel, and an annular groove is provided on the outer wall of the cylinder body. The second sealing ring is partially embedded in the annular groove and abuts against the upper and lower inner walls of the annular groove. The setting of the annular groove makes it more convenient to install and position the second sealing ring. The annular groove can also be used to limit the second sealing ring in the vertical direction, so as to prevent the first sealing ring and the second sealing ring from sliding freely on the outer wall of the cylinder body, and ensure that the sealing lip is always in a position where it can stably fit with the valve cover that closes the entrance of the water outlet channel, thereby ensuring that the valve cover seals the water outlet channel.

[0023] The second sealing ring includes a sealing ring embedded in the ring groove and a sealing lip connected to the outer side wall of the sealing ring. The sealing lip extends obliquely upward from the sealing ring and abuts against the opening of the kettle body. During the closing process between the kettle lid and the kettle body, the opening of the kettle body abuts against the sealing lip. As the kettle lid continues to extend into the kettle body, the opening of the kettle body presses the sealing lip toward the sealing ring, so that the outer side wall of the sealing lip fits tightly with the opening of the kettle body, so as to achieve the sealing of the kettle lid and the kettle body. The sealing lip extending obliquely upward can be quickly deformed toward the sealing ring when it is squeezed by the kettle lid, and the contact area between it and the kettle body is increased, so as to achieve a better sealing effect.

[0024] The water outlet valve also includes a valve stem connected to the top of the valve cover. The cover body is provided with a button for pushing the valve stem downward and an elastic reset member for pushing the valve stem upward. The elastic reset member is sleeved on the outer side of the valve stem. When the user presses the button, the button rotates around the mounting end to push the valve stem downward. The valve stem squeezes the elastic reset member and drives the valve cover downward to open the entrance of the water outlet channel, which is convenient for operation. When the user releases the button, the elastic reset member pushes the valve stem upward under the action of elastic force to drive the valve cover to close the entrance of the water outlet channel. At the same time, the upward-moving valve stem pushes the button upward to reset the button. The user does not need to reset it by himself, which improves the user's experience.

[0025] The cover body is also provided with an elastic member, the upper and lower ends of which respectively abut against the button and the cover body to push the button upward to reset. The top of the elastic member abuts against the button, and the lower end of the elastic member abuts against the cover body, so that the elastic member can always push the button upward under the action of elastic force. When the user releases the pressed button, the button is reset under the push of the elastic member, ensuring that the button always remains in a position where it does not push the valve stem downward, preventing the button from freely moving downward and pushing the valve cover downward away from the cover body to cause water leakage, and ensuring that the valve cover is sealed to the water outlet channel.

[0026] A positioning groove is provided on the cover body, a positioning column is provided on the button, the upper end of the elastic member is sleeved on the positioning column, and the lower end of the elastic member is embedded in the positioning groove, which can limit the spring in the horizontal direction to ensure that the top end of the spring always contacts the bottom surface of the button to maintain the push on the button, and at the same time facilitate the rapid installation and positioning of the spring.

[0050] Embodiment 1:

[0051] A thermos pot, such as Figures 1 to 5 As shown, the kettle body 100 and the kettle cover 200 covering the kettle body 100 are included. The kettle cover 200 includes a cover body 210 and a water outlet valve 220. The cover body 210 is provided with a water outlet channel 214 which is connected with the outside and the inside of the kettle body 100 for pouring water. The water outlet valve 220 is installed on the cover body 210, and includes a valve cover 222 located at the bottom of the water outlet channel 214. The user can open and close the entrance of the water outlet channel 214 by moving the valve cover 222 up and down. A first sealing ring 300 is provided at the bottom of the cover body 210. The first sealing ring 300 includes a connecting portion and a sealing lip 320. The connecting portion surrounds and is connected to the entrance wall of the water outlet channel 214. The sealing lip 320 is provided at the bottom of the connecting portion and is arranged around the water outlet channel 214. The sealing lip 320 extends along the opening direction of the valve cover 222 (i.e., downward), as shown in FIG. Figure 5 As shown, when the sealing lip 320 is not squeezed by the valve cover 222, the extension length in the vertical direction is h, and the valve cover 222 can move downward to move in the opening direction away from the water outlet channel 214. The maximum movable distance of the valve cover 222 (i.e., the height difference when the valve cover 222 closes the water outlet channel 214 and the height difference when the valve cover 222 opens the water outlet channel 214) is H, satisfying h<H.

[0052] The utility model provides a first sealing ring 300 with a sealing lip 320 at the entrance of the water inlet channel, so that when the valve cover 222 closes the water outlet channel 214, Figure 2As shown, the valve cover 222 abuts against the sealing lip 320 and presses the sealing lip 320 against the cover body 210. The sealing lip 320 is deformed toward the side of the cover body 210 under the pressure of the valve cover 222. The deformed sealing lip 320 is tightly fitted to the top surface of the valve cover 222 under the action of elastic force, so that the valve cover 222 can seal the entrance of the water outlet channel 214, so that the valve cover 222 has a better closing effect on the entrance of the water outlet channel 214. When the valve cover 222 moves slightly downward due to the virtual position problem of the button 500 or other reasons, When the sealing lip 320 is moved downward, the sealing lip 320 can be reset to the direction of the valve cover 222 under the action of elastic force, and fill the gap between the valve cover 222 and the inlet wall of the water outlet channel 214 when the valve cover 222 moves downward by its own deformation, so as to ensure that the sealing lip 320 is always closely fitted with the top surface of the valve cover 222, thereby ensuring that the valve cover 222 seals and covers the inlet of the water outlet channel 214, preventing the inlet of the water outlet channel 214 from opening freely and causing the water in the thermos pot to leak out through the water outlet channel 214, avoiding the leaked hot water from causing scalding to the user, and making it safer to use. Because the extension length of the sealing lip 320 is less than the maximum movable distance of the valve cover 222 along the opening direction, when the user needs to pour water, it is only necessary to control the downward movement distance of the valve cover 222 to be greater than the extension length of the sealing lip 320, so that a gap connecting the inside of the kettle body 100 and the water outlet channel 214 can be formed between the sealing lip 320 and the valve cover 222, so that the user can quickly pour the water in the kettle body 100 through the water outlet channel 214, thereby improving the user's use experience.

[0053] like Figure 4 As shown, the sealing lip 320 in this embodiment is in the shape of a trumpet with a small top and a large bottom, that is, the thickness of the sealing lip 320 is kept constant from top to bottom, and the inner diameter of the sealing lip 320 gradually increases from top to bottom. In the process of the valve cover 222 gradually approaching the water outlet channel 214 to close the entrance of the water outlet channel 214, the top surface of the valve cover 222 directly abuts against the inner side wall of the sealing lip 320, and pushes the sealing lip 320 to deform toward the outer peripheral side, so that the contact area between the top surface of the valve cover 222 and the sealing lip 320 gradually increases, greatly enhancing the sealing effect between the sealing lip 320 and the valve cover 222, ensuring that the valve cover 222 tightly covers the entrance of the water outlet channel 214, and having a good leakproof effect.

[0054] The pot cover 200 in this embodiment has a cylinder 211 (i.e., the inlet wall of the water outlet channel 214) surrounding the inlet of the water outlet channel 214, and the connecting portion is a ring 310 arranged around the water outlet channel 214, and the ring 310 abuts against the bottom surface of the cylinder 211. By abutting the ring 310 against the bottom surface of the cylinder 211 on the peripheral side of the inlet of the water outlet channel 214, the bottom surface of the cylinder 211 and the first sealing ring 300 can be sealed to prevent the water flow in the pot body 100 from entering the water outlet channel 214 through the gap between the first sealing ring 300 and the cylinder 211 and causing water leakage. Of course, it can be understood that the ring 310 is only a preferred embodiment of this embodiment, and the connecting portion in this embodiment can also be a non-circular structure, and any structure that can connect the sealing lip 320 to the cylinder 211 can be realized.

[0055] A second sealing ring 400 is sleeved on the outer wall of the cylinder 211. The second sealing ring 400 is located above the first sealing ring 300 and is integrally arranged with the first sealing ring 300. When the pot cover 200 is covered on the pot body 100, the gap between the pot cover 200 and the opening of the pot body 100 is sealed by the second sealing ring 400. By integrally arranging the first sealing ring 300 and the second sealing ring 400, during installation, the first sealing ring 300 is installed on the cover body 210, and the first sealing ring 300 and the second sealing ring 400 can be installed and positioned on the cover body 210 at the same time, and the first sealing ring 300 can be connected to the cover body 210 through the second sealing ring 400, and there is no need to fix the first sealing ring 300 and the cover body 210, which simplifies the assembly steps, reduces the assembly difficulty, and improves the assembly efficiency.

[0056] like Figure 3As shown, an annular groove 212 is provided on the outer wall of the cylinder 211, and the second sealing ring 400 includes a sealing ring 410 and a sealing lip 420 connected to the outer wall of the sealing ring 410. The sealing ring 410 includes a limiting portion embedded in the annular groove 212 and a mounting portion located outside the annular groove 212. The mounting portion is connected to the ring body 310 of the first sealing ring 300, and the upper and lower ends of the limiting portion are respectively abutted against the top wall and the bottom wall of the annular groove 212. The setting of the annular groove 212 makes it more convenient to install and position the second sealing ring 400, and the annular groove 212 can also be used to limit the second sealing ring 400 in the vertical direction, so as to prevent the first sealing ring 300 and the second sealing ring 400 from sliding freely on the outer wall of the cylinder 211, and ensure that the sealing lip 320 is always in a position where it can stably fit with the valve cover 222 that closes the entrance of the water outlet channel 214, thereby ensuring that the valve cover 222 is sealed and covers the water outlet channel 214. The sealing lip 420 extends obliquely upward from the sealing ring 410. During the closing process of the pot lid 200 and the pot body 100, the opening of the pot body 100 abuts against the sealing lip 420. As the pot lid 200 continues to extend into the interior of the pot body 100, the opening of the pot body 100 squeezes the sealing lip 420 toward the sealing ring 410, so that the outer side wall of the sealing lip 420 fits tightly against the opening of the pot body 100, thereby achieving sealing between the pot lid 200 and the pot body 100. The sealing lip 420 extending obliquely upward can quickly deform toward the sealing ring 410 when squeezed by the pot lid 200, thereby increasing the contact area between it and the pot body 100 and achieving a better sealing effect.

[0057] In this embodiment, if Figure 2As shown, the water outlet valve 220 also includes a valve stem 221 connected to the top of the valve cover 222, the valve stem 221 is inserted into the cover body 210, and the cover body 210 is provided with a button 500 and an elastic reset member 600, the button 500 includes a mounting end 510 extending into the cover body 210 and an operating end 520 located outside the cover body 210, the button 500 is located above the cover body 210, the mounting end 510 is rotatably connected to the cover body 210 through a rotating shaft, and the bottom of the middle position of the button 500 is against the top of the valve stem 221 to push the valve stem 221 downward, the elastic reset member 600 is sleeved on the outside of the valve stem 221, the upper end of the elastic reset member 600 is against the valve stem 221, and the lower end of the elastic reset member 600 is against the cover body 210. When the user presses the button 500, the button 500 rotates around the mounting end 510 to push the valve stem 221 downward. The valve stem 221 squeezes the elastic reset member 600 and drives the valve cover 222 to move downward to open the entrance of the water outlet channel 214 for easy operation. When the user releases the button 500, the elastic reset member 600 pushes the valve stem 221 upward under the action of elastic force to drive the valve cover 222 to close the entrance of the water outlet channel 214. At the same time, the upwardly moved valve stem 221 pushes the button 500 upward to reset the button 500. There is no need for the user to reset it by himself, thereby improving the user experience.

[0058] An elastic member 700 is also provided on the cover body 210. The elastic member 700 is arranged side by side on one side of the valve stem 221. The top of the elastic member 700 is against the button 500, and the lower end of the elastic member 700 is against the cover body 210, so that the elastic member 700 can always push the button 500 upward under the action of elastic force. When the user releases the pressed button 500, the button 500 is reset under the push of the elastic member 700, ensuring that the button 500 always remains in a position where it does not push the valve stem 221 downward, preventing the button 500 from freely moving downward and pushing the valve cover 222 downward away from the cover body 210 to cause water leakage, thereby ensuring that the valve cover 222 is sealed and covered with the water outlet channel 214. The abutting position of the valve stem 221 on the button 500 is between the abutting position of the elastic member 700 on the button 500 and the connection position of the rotating shaft, that is, the elastic member 700 abuts on the position of the button 500 close to the operating end, so as to facilitate the assembly of the button 500 with the valve stem 221 and the top of the elastic member 700. The elastic member 700 is preferably a spring. In order to limit the spring in the horizontal direction and ensure that the top of the spring always abuts against the bottom surface of the button 500 to maintain the push on the button 500 and facilitate the rapid installation and positioning of the spring, it is preferred in this embodiment that a positioning groove 213 is provided on the cover body 210, and a positioning column 530 is provided on the button 500. The upper end of the spring is sleeved on the positioning column 530, and the lower end of the spring is embedded in the positioning groove 213.

[0059] Embodiment 2:

[0060] like Figure 6 and Figure 7 As shown, the difference between this embodiment and embodiment one is that, in this embodiment, two sealing lips are provided, and the two sealing lips are an inner sealing lip 321 and an outer sealing lip 322 respectively. The inner sealing lip 321 and the outer sealing lip 322 are concentrically arranged at the bottom of the ring body 310, and the outer sealing lip 322 is arranged on the outer peripheral side of the inner sealing lip 321, and a sealing gap 323 is formed between the inner sealing lip 321 and the outer sealing lip 322. In the process of the valve cover 222 gradually approaching the water outlet channel 214 to close the entrance of the water outlet channel 214, the top surface of the valve cover 222 contacts the inner sealing lip 321 and the outer sealing lip 322 at the same time and pushes the two to deform. The sealing gap 323 can provide space for deformation, so that the deformed inner sealing lip 321 and the outer sealing lip 322 can fit tightly on the top surface of the valve cover 222 under the action of elastic force. The double-layer sealing setting can complement each other, so that when one of the inner sealing lip 321 and the outer sealing lip 322 is damaged, the first sealing ring can still be sealed and fit with the valve cover 222.

[0061] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
