Description

Technical Field

[0001] The utility model belongs to the field of drinking water equipment, and particularly relates to a kettle. Background Art

[0002] Currently, kettles on the market usually use software to set the water-drawing time, and automatically stop adding water to the kettle when the water-drawing time is reached. When there is water in the kettle, too much water is often drawn, causing the water in the kettle to overflow, or the water flow exceeds the highest water level line. When the water boils, the boiling water can easily splash out of the kettle mouth, causing scalds to the user.

[0003] To solve this problem, some kettles are equipped with an upper liquid level electrode to detect the maximum liquid level, so that the kettle can only draw water to the maximum liquid level where the upper liquid level electrode is located. Although this prevents the water flow from exceeding the maximum liquid level, this solution requires the water flow to reach the maximum liquid level every time the kettle draws water. That is, when the user uses the kettle, the kettle needs to draw the maximum amount of water, resulting in a long waiting time for the kettle to heat up, and a single person cannot finish a kettle of hot water, resulting in waste. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a kettle to solve at least one of the above problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a kettle, comprising a kettle body, a handle, and a liquid level control assembly. The liquid level control assembly comprises a sleeve installed in the kettle body, a screw vertically extending through the sleeve, a screw nut sleeved on the screw, an electrode sheet fixed to the screw nut, and a drive mechanism for driving the screw to rotate. The sleeve is provided with a sliding hole, through which the electrode sheet passes through the sleeve and is slidably connected to the sliding hole. When the drive mechanism drives the screw in the sleeve to rotate, the screw nut drives the electrode sheet to rise and fall within the sliding hole, thereby adjusting the maximum liquid level in the kettle body through the electrode sheet. This technical solution has the following technical effects:

[0006] The present invention provides a liquid level control assembly on the kettle body, so that a drive mechanism can drive a screw to rotate within a sleeve, thereby causing a screw nut threaded onto the screw to drive an electrode plate to rise and fall within a sliding hole on the sleeve, thereby achieving the raising and lowering of the electrode plate within the kettle body. The electrode plate can detect the liquid level within the kettle body, so that when the liquid level reaches the height of the electrode plate during the water filling process, water is stopped from entering the kettle body. The liftable electrode plate allows the adjustment of the maximum liquid level when the kettle is filling. During use, the user can adjust the height of the electrode plate within the kettle body according to actual needs, thereby adjusting the amount of water the kettle can take, thereby avoiding excessive water intake and overflow, and also avoiding the water flow exceeding the maximum water intake of the kettle, resulting in boiling water splashing out of the kettle mouth and causing burns to the user. In addition, the user can take a small amount of water by lowering the height of the electrode plate within the kettle body, thereby avoiding excessive water intake and waste, while shortening the heating time of the liquid in the kettle body, thereby reducing the user's waiting time and improving the user experience.

[0007] In the aforementioned kettle, the liquid level control assembly further includes a transmission mechanism connected to the top of the screw. The drive mechanism is located outside the kettle body, and an output shaft of the drive mechanism passes through the kettle body and is connected to the transmission mechanism, thereby driving the screw to rotate via the transmission mechanism. By providing the transmission mechanism, the drive mechanism can be located outside the kettle body to drive the screw, thereby preventing water vapor within the kettle body from damaging the drive mechanism and extending the service life of the drive mechanism. Because the transmission mechanism is located at the top of the screw, it is located above the electrode sheet, so that the liquid level within the kettle body will not reach the hole in the kettle body for inserting the output shaft of the drive mechanism, thereby reducing the possibility of water leakage.

[0008] In the aforementioned kettle, the transmission mechanism includes a worm gear and a worm. The worm gear is mounted on top of the lead screw to engage with the lead screw, and the worm gear is mounted on the output shaft of the drive mechanism to engage with the output shaft. The worm gear and the worm gear mesh to transmit power. When the horizontally extending output shaft of the drive mechanism rotates, the worm gear rotates, which in turn drives the worm gear meshed with the worm gear, and ultimately drives the vertically extending lead screw. In other words, the meshing worm gear and worm gear can change the transmission direction, making it easier to install the drive mechanism on the outside of the kettle body and reducing assembly difficulty.

[0009] In the aforementioned kettle, the transmission mechanism includes a first bevel gear and a second bevel gear. The first bevel gear is mounted on top of the lead screw to interlock with the lead screw, and the second bevel gear is mounted on an output shaft of the drive mechanism to interlock with the output shaft. The first bevel gear and the second bevel gear mesh together to transmit the power. When the horizontally extending output shaft of the drive mechanism rotates, the second bevel gear rotates, which in turn rotates the first bevel gear meshed with the second bevel gear, and ultimately rotates the vertically extending lead screw. In other words, the meshed first and second bevel gears can change the transmission direction, making the coupling more stable and reliable.

[0010] In the kettle described above, a protective sleeve is provided on the top of the sleeve, and the transmission mechanism is disposed within the protective sleeve. The protective sleeve can block water vapor within the kettle body and protect the transmission mechanism, preventing water vapor from condensing on the transmission mechanism and flowing out of the kettle body along the output shaft of the drive mechanism, thereby damaging the drive mechanism and extending the service life of the drive mechanism.

[0011] In the kettle, a mounting hole is provided on the side wall of the kettle body, through which the handle extends into the kettle body and plugs into the protective cover. The handle can be used to position the protective cover, thereby reducing the difficulty of assembling the liquid level control component and improving assembly efficiency.

[0012] In the kettle described above, the drive mechanism is a motor mounted within the handle, with the motor's output shaft extending through the kettle body to connect to the transmission mechanism. The motor makes operation more convenient and labor-saving for the user. Mounting the motor within the handle protects and conceals the motor, shielding it from external impact and enhancing the kettle's aesthetics.

[0013] In the aforementioned kettle, the driving mechanism is a knob, which includes an output shaft and a knob cap for rotating the output shaft. The knob cap is mounted on the outer wall of the kettle body, and the output shaft passes through the kettle body to connect to the transmission mechanism. When a user turns the knob cap, the output shaft drives the lead screw through the transmission mechanism. The knob allows the user to control the rotation of the lead screw, thereby controlling the raising and lowering of the electrode sheet, by turning the knob. The purely mechanical structure is not easily damaged.

[0014] In the kettle described above, a base plate enclosing the sleeve is provided at the bottom of the sleeve. A support ball is disposed within the sleeve, contacting the bottom surface of the screw and the top surface of the base plate, respectively. The base of the screw and the support ball form a point contact, which prevents direct contact between the base and the base plate. This reduces wear on the base of the screw during rotation and extends the life of the screw.

[0015] In the aforementioned kettle, a screw post is provided on the outer wall of the sleeve, abutting against the inner wall of the kettle body. A locking screw extends through the side wall of the kettle body and into the screw post to secure the sleeve to the kettle body. The locking screw is threadedly connected to the screw post, securing the sleeve to the kettle body, preventing the sleeve from shaking inside the kettle body, ensuring stable raising and lowering of the electrode sheet within the kettle body, and enhancing the user experience.

DETAILED DESCRIPTION

[0027] The present invention provides a kettle, comprising a kettle body, a handle, and a liquid level control assembly. The liquid level control assembly comprises a sleeve mounted within the kettle body, a screw rod vertically inserted within the sleeve, a screw nut sleeved on the screw rod, an electrode sheet fixed to the screw nut, and a drive mechanism for driving the screw rod to rotate. The sleeve is provided with a sliding hole, through which the electrode sheet passes through the sleeve and is slidably connected to the sliding hole. When the drive mechanism drives the screw rod within the sleeve to rotate, the screw nut drives the electrode sheet to rise and fall within the sliding hole, thereby adjusting the maximum liquid level within the kettle body through the electrode sheet. The present invention provides a liquid level control assembly on the kettle body, so that the drive mechanism can drive the screw rod to rotate within the sleeve, thereby causing the screw nut threadedly connected to the screw rod to drive the electrode sheet to rise and fall within the sliding hole on the sleeve, thereby achieving the raising and lowering of the electrode sheet within the kettle body. The electrode sheet can detect the liquid level within the kettle body, so that when the water level reaches the height of the electrode sheet during the water filling process, the water supply to the kettle body stops. The liftable electrode plate realizes the adjustment of the maximum liquid level when the kettle is filled with water. When in use, the user can adjust the height of the electrode plate in the kettle body according to actual needs, and then adjust the water intake of the kettle to avoid excessive water intake and overflow of water, and also avoid the water flow exceeding the maximum water intake of the kettle, causing boiling water to splash out of the kettle mouth when the water boils and cause scalding of the user. In addition, the user can take out a small amount of water by lowering the height of the electrode plate in the kettle body to avoid waste caused by excessive water intake, and at the same time shorten the heating time of the liquid in the kettle body, thereby reducing the user's waiting time and improving the user experience.

[0033] Example 1:

[0034] A kettle, such as Figures 1 to 5 As shown, it includes a kettle body 100, a handle 200 and a liquid level control assembly 300. The handle 200 is installed on the outer wall of the kettle body 100. The liquid level control assembly 300 includes a sleeve 310, a screw rod 320, a screw nut 330, an electrode piece 340 and a driving mechanism 350. The sleeve 310 is installed in the kettle body 100 and is hollow inside. The screw rod 320 is vertically penetrated inside the sleeve 310. The sleeve 310 limits the screw rod 320 in the vertical direction. The driving mechanism 350 is installed outside the kettle body 100 and is connected to the screw rod 320 to drive the screw rod 320 to rotate. The screw nut 330 is sleeved on the screw rod 320 and is threadedly connected to the screw rod 320. The sleeve 310 can limit the screw rod 320 in the horizontal direction through the screw nut 330. The electrode piece 340 is fixed on the outer wall of the screw nut 330 to detect the highest liquid level in the kettle body 100. Figure 3When the cam 330 is in the closed position, the cam 330 can be rotated in the closed position, so that the cam 330 can be rotated in the closed position, and the cam 330 can be rotated in the open position, so that the cam 330 can be rotated in the closed position, and the cam 330 can be rotated in the closed position, so that the cam 330 can be rotated in the closed position, and the cam 330 can be rotated in the closed position, so that the cam 330 can be rotated in the closed position, and the cam 330 can be rotated in the closed position, so that the cam 330 can be rotated in the closed position, and the cam 330 can be rotated in the closed position, so that the cam 330 can be rotated in the closed position, and the cam 330 can be rotated in the closed position, so that the cam 330 can be rotated in the closed position, and the cam 330 can be rotated in the closed position,

[0035] The present invention arranges a liquid level control assembly 300 on the kettle body 100, so that the driving mechanism 350 can drive the screw rod 320 to rotate in the sleeve 310, and then the screw nut 330 threadedly connected to the screw rod 320 drives the electrode piece 340 to rise and fall in the sliding hole 311 on the sleeve 310, thereby realizing the lifting and lowering of the electrode piece 340 in the kettle body 100. The electrode piece 340 can detect the liquid level in the kettle body 100, so that when the liquid level reaches the height of the electrode piece 340 during the water intake process of the kettle, the water intake into the kettle body 100 is stopped. The liftable electrode sheet 340 realizes the adjustment of the maximum liquid level when the kettle is filled with water. When in use, the user can adjust the height of the electrode sheet 340 in the kettle body 100 according to actual needs, and then adjust the water intake of the kettle to avoid the kettle taking in too much water and causing water overflow, and also to avoid the water flow exceeding the maximum value of the water that the kettle can take out, causing boiling water to splash out of the kettle mouth when the water boils and cause scalding to the user. In addition, the user can take in a small amount of water by lowering the height of the electrode sheet 340 in the kettle body 100 to avoid waste caused by excessive water intake, and at the same time shorten the heating time of the liquid in the kettle body 100, thereby reducing the user's waiting time and improving the user's experience.

[0036] like Figure 1As shown, the liquid level control assembly 300 further includes a transmission mechanism 360, which is connected to the top of the screw rod 320. The output shaft 351 of the drive mechanism 350 passes through the kettle body 100 and is connected to the transmission mechanism 360. The transmission mechanism 360 transmits power between the drive mechanism 350 and the top of the screw rod 320, so that the output shaft 351 of the drive mechanism 350 drives the screw rod 320 to rotate through the transmission mechanism 360. By providing the transmission mechanism 360, the drive mechanism 350 can be arranged outside the kettle body 100 to drive the screw rod 320, thereby preventing water vapor in the kettle body 100 from damaging the drive mechanism 350 and extending the service life of the drive mechanism 350. Because the transmission mechanism 360 is arranged on the top of the screw rod 320, the transmission mechanism 360 is located above the electrode sheet 340. Therefore, the liquid level in the kettle body 100 will not reach the hole in the kettle body 100 for the output shaft 351 of the drive mechanism 350, thereby reducing the possibility of water leakage.

[0037] like Figure 4 and Figure 5 As shown, in this embodiment, preferably, the transmission mechanism 360 includes a worm wheel 361 and a worm 362. The worm wheel 361 is sleeved on the top of the screw 320 and is circumferentially linked with the screw 320. The worm 362 is sleeved on the output shaft 351 of the driving mechanism 350 and is circumferentially linked with the output shaft 351. The worm wheel 361 is meshed with the worm 362. When the horizontally extending output shaft 351 of the driving mechanism 350 rotates, it drives the worm 362 to rotate, and then drives the worm wheel 361 meshed with the worm 362 to rotate, and finally drives the vertically extending screw 320 to rotate. That is, the meshed worm wheel 361 and worm 362 can change the transmission direction, so that the driving mechanism 350 can be installed on the outside of the kettle body 100, reducing the difficulty of assembly.

[0038] In order to protect the transmission mechanism 360, a protective cover 312 is provided on the top of the sleeve 310 in this embodiment. The transmission mechanism 360 is arranged in the protective cover 312. The protective cover 312 and the sleeve 310 are an integral structure. The protective cover 312 can block the water vapor in the kettle body 100 to prevent the water vapor from condensing on the transmission mechanism 360 and flowing out of the kettle body 100 along the output shaft 351 of the drive mechanism 350 to damage the drive mechanism 350, thereby extending the service life of the drive mechanism 350. Figure 2 As shown, in this embodiment, the side wall of the kettle body 100 is provided with a mounting hole 110 that passes through the side wall of the kettle body 100. Figure 1As shown, the handle 200 extends into the kettle body 100 through the mounting hole 110 and is plugged into the protective cover 312. The handle 200 can be used to install and position the protective cover 312, reducing the difficulty of assembling the liquid level control assembly 300 and improving assembly efficiency. Preferably, the drive mechanism 350 is a motor, making user operation more convenient and labor-saving. The motor is installed in the handle 200, and the output shaft 351 of the motor passes through the kettle body 100 together with the handle 200 to connect with the transmission mechanism 360. By installing the motor in the handle 200, the motor is protected and hidden, preventing the motor from being impacted by external forces, while making the exterior of the kettle more beautiful.

[0039] like Figure 4 As shown, in this embodiment, a bottom plate 313 is provided at the bottom of the sleeve 310, and the bottom plate 313 seals the bottom of the sleeve 310. A support ball 314 is provided in the sleeve 310, and the support ball 314 is located between the top surface of the bottom plate 313 and the bottom surface of the screw rod 320, and abuts against the two respectively. The support ball 314 is in point contact with the bottom of the screw rod 320 and the bottom plate 313. The setting of the support ball 314 can avoid direct contact between the bottom of the screw rod 320 and the bottom plate 313, reduce the wear on the bottom of the screw rod 320 and the bottom plate 313 when the screw rod 320 rotates, and extend the service life of the screw rod 320.

[0040] In this embodiment, a screw column 315 is provided on the outer wall of the sleeve 310, and the screw column 315 is abutted against the inner wall of the kettle body 100. The locking screw 316 passes through the side wall of the kettle body 100 and extends into the screw column 315 to be threadedly connected with the screw column 315, thereby realizing locking between the sleeve 310 and the kettle body 100, preventing the sleeve 310 from shaking inside the kettle body 100, ensuring the stable lifting and lowering of the electrode sheet 340 in the kettle body 100, and thus ensuring the user experience.

[0041] Example 2:

[0042] The difference between this embodiment and the first embodiment is that, in this embodiment, the transmission mechanism includes a first bevel gear and a second bevel gear, that is, the first bevel gear and the second bevel gear are used to replace the worm gear and the worm in the first embodiment. The first bevel gear is sleeved on the top of the screw and is circumferentially linked with the screw. The second bevel gear is sleeved on the output shaft of the driving mechanism and is circumferentially linked with the output shaft of the driving mechanism. The first bevel gear and the second bevel gear are meshed so that when the horizontally extending output shaft of the driving mechanism rotates, the second bevel gear is driven to rotate, thereby driving the first bevel gear meshed with the second bevel gear to rotate, and finally driving the vertically extending screw to rotate, that is, the meshed first bevel gear and the second bevel gear can change the transmission direction, and the cooperation is more stable and reliable.

[0043] Example 3:

[0044] This embodiment differs from the first embodiment in that the drive mechanism is a knob in this embodiment. The knob includes an output shaft and a knob cap. The output shaft and the knob cap are integrally arranged for interlocking movement. The knob cap is mounted on the outer wall of the kettle body, and the output shaft passes through the kettle body to connect to the transmission mechanism. When the user turns the knob cap, the output shaft drives the lead screw through the transmission mechanism. The knob allows the user to control the rotation of the lead screw, thereby controlling the raising and lowering of the electrode sheet, by turning the knob. The purely mechanical structure is not easily damaged.

[0045] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
