Description

Magnetic ring assembly, water tank assembly and humidifier

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on October 30, 2023, with application number 202322911401.X. The entire contents of this application are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of humidifiers, and in particular to a magnetic ring assembly, a water tank assembly and a humidifier. Background Art

[0003] A humidifier is a household appliance that increases the humidity in a room. It consists of a base assembly and a water tank assembly mounted on top of it. During use, the humidifier continuously converts water into mist and emits it. To prevent internal electronic components from drying out after the water is depleted, a water level detection device is required. Furthermore, to prevent the humidifier's main unit from continuing to operate when the water tank assembly is removed for refilling, a device is also required to detect when the water tank is detached.

[0004] To achieve this function, one related solution involves a magnetic ring fixed to the bottom of the water tank and a detection component installed within the base. When the water tank is placed on the base, the detection component senses the magnetic force of the magnetic ring, connecting the entire circuit. When the water tank is removed from the base, the detection component separates from the magnetic ring, disconnecting the entire circuit. This structure causes the magnetic ring to protrude further than the existing protrusion on the bottom of the water tank, making it difficult to lay flat when the water tank is removed and easily tipping over.

[0005] Another solution in the related art is to install a water level detection device in the base to detect water level changes in the water tank. A water tank lifting and lowering status detection device is also installed. Specifically, a magnet is installed on the water tank, and a Hall effect device is added to the base to sense the lifting and lowering status of the water tank. When the water tank assembly is placed in the base assembly, the magnet and the Hall effect device are connected, connecting the entire circuit. When the water tank assembly is lifted, the Hall effect device and the magnet are separated, disconnecting the entire circuit. This structural detection device is complex and increases product cost.

[0006] Summary of the Invention

[0007] Based on the above, the purpose of this application is to provide a magnetic ring assembly, a water tank assembly and a humidifier, which can be placed stably when the water tank assembly is removed and placed separately to prevent the water tank assembly from tipping over; and can reduce the setting of detection elements and reduce costs.

[0018] In some possible embodiments, a fourth connecting wall extending downward is provided at the lower portion of the magnetic ring connecting seat, and the fourth connecting wall is located on the outer side of the second connecting wall and the inner side of the first connecting wall; when the magnetic ring assembly is in the second position, the fourth connecting wall is used to limit the upward position of the magnetic ring so that the magnetic ring is located within the detection range of the detection assembly.

[0019] In some possible embodiments, the magnetic ring connecting seat includes a fifth connecting wall, the fifth connecting wall is located on the outside of the first connecting wall, a second mounting groove is provided between the fifth connecting wall and the first connecting wall, the elastic member is sleeved on the outside of the first connecting wall, and the lower end of the elastic member is installed in the second mounting groove.

[0020] In some possible implementations, the elastic member is a compression spring.

[0021] On the other hand, the present application also provides a water tank assembly, comprising a water tank and a protruding structure provided at the bottom of the water tank. The bottom of the water tank is also installed with the magnetic ring assembly described in any of the above schemes, and the magnetic ring assembly has a first position away from the bottom of the water tank and a second position close to the bottom of the water tank. When the magnetic ring assembly is forced to move to the first position, the detection assembly in the base can pass through the first through hole and the second through hole in sequence to detect the position of the magnetic ring; when the magnetic ring assembly is forced to move to the second position, the lower end of the magnetic ring fixing seat is flush with the lower end of the protruding structure.

[0022] On the other hand, the present application also provides a humidifier, including a base assembly, the base assembly including a base and a detection assembly arranged in the base, and also including a water tank assembly as mentioned above, the water tank assembly can be detachably installed above the base assembly, when the water tank assembly is installed on the base assembly, the magnetic ring assembly is forced to move to a first position, and the detection assembly can pass through the first through hole and the second through hole in sequence to detect the position of the magnetic ring; when the water tank assembly is removed and placed on an external platform, the magnetic ring assembly is forced to move to a second position, and the lower end of the magnetic ring fixing seat is flush with the lower end of the protruding structure.

[0023] The beneficial effects of this application are:

[0024] The magnetic ring assembly provided by the present application has a magnetic ring fixing seat movably connected to the water tank through a magnetic ring connecting seat.

At this time, the magnetic ring is within the detection range of the detection assembly, the detection assembly senses the magnetic ring, and the entire machine circuit is connected; during the operation of the humidifier, the magnetic ring floats up and down with the change of the water level in the water tank to detect the water level in the water tank and prevent dry burning; when the water tank assembly is removed from the base assembly, the magnetic ring is separated from the detection assembly, and the entire machine circuit is disconnected, achieving the effect of powering off by lifting the water tank assembly; when the water tank assembly is placed alone on the desktop, the magnetic ring assembly is subjected to force (such as the force of the water tank and the desktop) to move upward to the second position. At this time, the lower end of the magnetic ring fixing seat is flush with the lower end of the protruding structure at the bottom of the water tank, so that the water tank assembly can be placed stably to prevent the water tank assembly from tipping over. In addition, compared with the solution in the related art in which a water level detection device and a water tank lifting and lowering status detection device are separately provided, the present application reduces detection devices such as Hall devices and magnets, thereby effectively reducing product costs.

[0025] The water tank assembly provided by the present application has a magnetic ring assembly that can move up and down at the bottom of the water tank. When the water tank assembly is placed alone on a table, the magnetic ring assembly moves up and retracts to a second position, so that the lower end of the magnetic ring fixing seat is flush with the lower end of the protruding structure at the bottom of the water tank. The magnetic ring assembly and the protruding structure jointly support the water tank to ensure the horizontality of the water tank, allowing the water tank assembly to be stably placed on the table. When the water tank assembly is installed in the base assembly, the magnetic ring assembly moves down and extends to the first position, so that the magnetic ring assembly cooperates with the detection assembly to detect the water level in the sink and the lifting and lowering status of the water tank. The water tank assembly has a simple structure and fewer detection components, effectively reducing costs.

[0026] The humidifier provided in the present application has a water tank assembly that is stable and not easy to tip over when placed on a table; the magnetic ring assembly cooperates with the detection assembly to simultaneously detect the water level in the water tank and the lifting and lowering status of the water tank. It is safe and reliable to use, simplifies the detection device, and reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Example 1

[0056] This embodiment provides a magnetic ring assembly 120 that can be used in a humidifier to solve the problems that the water tank assembly 100 of the existing humidifier is easy to tip over when placed independently, and the detection device of the existing humidifier has a complex structure and high product cost.

[0057] As shown in Figures 1 to 14, the magnetic ring assembly 120 provided in this embodiment is installed at the bottom of the water tank 110 of the humidifier and can move up and down relative to the bottom of the water tank 110. The magnetic ring assembly 120 can form a support for the placement of the water tank assembly 100 together with the original protruding structure 111 (such as a mist-sealing structure, etc.) at the bottom of the water tank 110. Specifically, the magnetic ring assembly 120 of this embodiment includes a magnetic ring connecting seat 121, a magnetic ring fixing seat 122, and a magnetic ring 123. The magnetic ring connecting seat 121 can be connected to the bottom of the water tank 110 so as to move up and down, for example, it can extend downward or retract upward relative to the bottom of the water tank 110 through a sliding structure. The magnetic ring holder 122 is fixedly connected to the bottom of the magnetic ring connection base 121. A cavity is provided within the magnetic ring holder 122 for accommodating the magnetic ring 123. A first through-hole 1221 is provided at the bottom of the magnetic ring holder 122 to facilitate insertion of the detection assembly 220 within the humidifier base 210. The sidewalls of the magnetic ring holder 122 also have several openings to allow water from the water tank of the base 210 to enter the magnetic ring holder 122, allowing the magnetic ring 123 to float up and down within the magnetic ring holder 122 depending on the water level. A second through-hole 1231 is provided through the magnetic ring 123. The position of the second through-hole 1231 corresponds to the position of the first through-hole 1221. The detection assembly 220 can pass through the first and second through-holes 1221, 1231, from bottom to top. Optionally, the detection assembly 220 is a Hall effect element capable of sensing the different height positions of the magnetic ring 123. The magnetic ring assembly 120 of this embodiment has a first position away from the bottom of the water tank 110 and a second position close to the bottom of the water tank 110. When the magnetic ring assembly 120 is in the first position, it can cooperate with the detection assembly 220 for detection; when the magnetic ring assembly 120 is in the second position, the lower end of the magnetic ring fixing seat 122 is flush with the lower end of the protruding structure 111.

[0058] In this embodiment, when the water tank assembly 100 is placed in the base assembly 200, the magnetic ring assembly 120 is extended downward to the first position by a force (such as its own gravity or the force of the elastic member), and the detection assembly 220 in the base 210 can pass through the first through hole 1221 and the second through hole 1231 in sequence and be inserted into the magnetic ring 123. At this time, the magnetic ring 123 is within the detection range of the detection assembly 220, and the detection assembly 220 senses the magnetic ring, and the entire circuit is connected; during the operation of the humidifier, the magnetic ring 123 floats up and down with the change of the water level in the water tank to detect the water level in the water tank and prevent Prevent dry burning; when the water tank assembly 100 is removed from the base assembly 200, the magnetic ring 123 is separated from the detection assembly 220, and the entire machine circuit is disconnected, achieving the effect of powering off by lifting the water tank assembly 100; when the water tank assembly 100 is placed alone on the desktop, the magnetic ring assembly 120 is subjected to force (such as the force of the water tank 110 and the desktop) and moves upward to the second position. At this time, the lower end of the magnetic ring fixing seat 122 is flush with the lower end of the protruding structure 111 at the bottom of the water tank 110, so that the water tank assembly 100 can be placed stably and prevent the water tank assembly 100 from tipping over. In addition, this embodiment realizes water level detection and water tank lifting and lowering status detection through the cooperation of the magnetic ring assembly 120 and the detection assembly 220. Compared with the related technology of independently setting up two sets of detection devices, the use of detection elements such as Hall devices and magnets is reduced, effectively reducing product costs.

[0059] Optionally, in order to achieve a sliding connection between the magnetic ring connecting seat 121 and the bottom of the water tank 110, this embodiment is provided with a connecting pipe 112 at the bottom of the water tank 110, and the magnetic ring connecting seat 121 is provided with an annular first connecting wall 1211, which is sleeved on the outer side of the connecting pipe 112 and can slide up and down relative to the first connecting wall 1211. Furthermore, the first connecting wall 1211 and the connecting pipe 112 are limited by a limiting assembly. Optionally, the limiting assembly includes a limiting buckle 1121 provided at the lower end of the connecting pipe 112 and a limiting platform 12111 provided on the inner side of the first connecting wall 1211. When the magnetic ring connecting seat 121 moves downward to the maximum position (i.e., the first position), the limiting buckle 1121 and the limiting platform 12111 are engaged to prevent the magnetic ring connecting seat 121 from sliding off the connecting pipe 112. In addition, in order to achieve the fixation of the magnetic ring connecting seat 121 and the magnetic ring fixing seat 122, in this embodiment, a first fixing groove is provided at the lower end of the first connecting wall 1211, and a plug-in portion is provided at the upper end of the side wall of the magnetic ring fixing seat 122. The plug-in portion is inserted into the first fixing groove and can be fixed to the first fixing groove by bonding, welding, clamping, etc.

[0060] Furthermore, to guide the movement of the magnetic ring connector 121, a downwardly extending guide post 113 is provided at the bottom of the water tank 110. The guide post 113 is located inside the connecting tube 112. The magnetic ring connector 121 is also provided with an annular second connecting wall 1212. The second connecting wall 1212 is located inside the first connecting wall 1211. The second connecting wall 1212 is sleeved outside the guide post 113 and can slide up and down along the guide post 113. The provision of the guide post 113 makes the movement of the magnetic ring connector 121 smoother and more reliable.

[0061] Optionally, the magnetic ring assembly 120 of this embodiment further includes an elastic member 124, which elastically abuts between the magnetic ring connecting seat 121 and the bottom of the water tank 110. When the water tank assembly 100 is placed on the base assembly 200, the elastic force of the elastic member 124 causes the magnetic ring assembly 120 to move downward as a whole to a first position, so that the magnetic ring 123 cooperates with the detection assembly 220 in the base 210. When the water tank assembly 100 is removed from the base assembly 200 and placed separately on a desktop, the magnetic ring assembly 120 moves upward to a second position under the combined action of the gravity of the water tank 110 and the support force of the desktop. At this time, the elastic member 124 is compressed, and the lower end of the magnetic ring fixing seat 122 is flush with the lower end of the protruding structure 111, facilitating the stable placement of the water tank assembly 100. Optionally, the elastic member 124 of this embodiment is a compression spring.

[0062] Furthermore, to facilitate installation of the elastic member 124, the upper portion of the magnetic ring connector 121 of this embodiment is further provided with an upwardly extending third connecting wall 1213. The third connecting wall 1213 is annular and located outside the second connecting wall 1212 and inside the first connecting wall 1211. A first mounting groove 1216 is formed between the third connecting wall 1213 and the second connecting wall 1212. The elastic member 124 is sleeved outside the second connecting wall 1212, with the upper end of the elastic member 124 abutting the bottom of the water tank 110 and the lower end of the elastic member 124 mounted in the first mounting groove 1216. This arrangement offers a simple structure and convenient assembly, ensuring the reliability of the elastic member 124 and preventing positional displacement of the elastic member 124.

[0063] Furthermore, to limit the maximum floating position of the magnetic ring 123 within the magnetic ring fixing seat 122, this embodiment further provides a fourth connecting wall 1214 extending downwardly at the lower portion of the magnetic ring connecting seat 121. When the water tank assembly 100 is placed on the base assembly 200, the magnetic ring assembly 120 moves downward to the first position, and the magnetic ring 123 floats upward due to the buoyancy of the water in the water tank. When the magnetic ring 123 floats up to abut against the fourth connecting wall 1214, it has reached its maximum floating position and cannot move further upward. The above arrangement limits the floating position of the magnetic ring 123 to the detection range of the detection assembly 220, preventing the detection assembly 220 from failing to detect the magnetic ring 123. It should be noted that although the magnetic ring 123 cannot move further upward when it floats to the highest position, it indicates that the water level in the water tank is not lower than the preset safety water level at this time, and the humidifier can be used normally. Optionally, the fourth connecting wall 1214 of this embodiment is also annular and is located on the outer side of the second connecting wall 1212 and the inner side of the first connecting wall 1211; the diameter of the fourth connecting wall 1214 matches the diameter of the magnetic ring 123, so that the bottom end of the fourth connecting wall 1214 can abut against the top end of the magnetic ring 123.

[0064] Example 2

[0065] As shown in Figures 15-18 , this embodiment provides another magnetic ring assembly 120, which is substantially identical in structure to the magnetic ring assembly of the first embodiment, except that the magnetic ring assembly 120 of this embodiment does not include the elastic member 124. Accordingly, the third connecting wall 1213 and the first mounting groove 1216 may also be omitted from the magnetic ring connecting seat 121.

[0066] In this embodiment, when the water tank assembly 100 is placed on the base assembly 200, the magnetic ring assembly 120 naturally falls to the bottom of the base assembly 200 under the action of its own gravity. At this time, the detection assembly 220 in the base 210 can be inserted into the magnetic ring 123, which can realize the detection of the water level in the sink and the detection of the lifting and lowering status of the water tank; when the water tank assembly 100 is taken out from the base assembly 200 and placed on the desktop, since the magnetic ring assembly 120 is movably connected to the bottom of the water tank 110 through the magnetic ring connecting seat 121, the bottom of the magnetic ring assembly 120 is flush with the bottom of the protruding structure 111 under the two-way squeezing of the water tank 110 and the desktop, thereby achieving the effect of placing the water tank assembly 100 flat on the desktop.

[0067] Example 3

[0068] As shown in Figures 19 to 24, this embodiment provides another magnetic ring assembly 120, which has basically the same structure as the magnetic ring assembly of Example 1, except that: the guide column 113 is not provided in the magnetic ring assembly 120 of this embodiment, and the second connecting wall 1212, the third connecting wall 1213, the fourth connecting wall 1214 and the first mounting groove 1216 are cancelled.

[0069] In this embodiment, the magnetic ring connector 121 includes a first connecting wall 1211 and a fifth connecting wall 1215. The inner wall of the first connecting wall 1211 is slidably connected to the outer wall of the connecting tube 112, guiding the up and down movement of the magnetic ring connector 121. This eliminates the need for a dedicated guide post 113, further simplifies the structure of the magnetic ring assembly 120, and reduces costs. The fifth connecting wall 1215 is annular and located outside the first connecting wall 1211. A second mounting groove 1217 is formed between the fifth connecting wall 1215 and the first connecting wall 1211. In this embodiment, the elastic member 124 is sleeved outside the first connecting wall 1211. The upper end of the elastic member 124 abuts the bottom of the water tank 110, and the lower end of the elastic member 124 is mounted in the second mounting groove 1217. This arrangement offers a simple structure and easy assembly, ensuring the reliability of the elastic member 124 and preventing it from shifting. Furthermore, the elastic member 124 in this embodiment is a compression spring. Further optionally, the length setting of the connecting tube 112 of this embodiment can be adapted to the lowest position of the magnetic ring 123 in the magnetic ring fixing seat 122, that is: when the magnetic ring assembly 120 moves upward to the second position, the lower end of the connecting tube 112 can abut against the upper end of the magnetic ring 123, and the magnetic ring 123 is restricted to the bottom position of the magnetic ring fixing seat 122, further ensuring the stability of the water tank assembly 100 when placed.

[0070] In addition, in order to achieve the fixation of the magnetic ring connecting seat 121 and the magnetic ring fixing seat 122, a second fixing groove is provided at the lower end of the fifth connecting wall 1215 of this embodiment, and a plug-in portion is provided at the upper end of the side wall of the magnetic ring fixing seat 122. The plug-in portion is inserted into the second fixing groove and can be fixed to the second fixing groove by bonding, welding, clamping, etc.

[0071] The working principle of this embodiment is the same as that of the first embodiment: when the water tank assembly 100 is placed on the base assembly 200, the elastic force of the elastic member 124 causes the magnetic ring assembly 120 to move downward as a whole to the first position, so that the magnetic ring 123 cooperates with the detection assembly 220 in the base 210; when the water tank assembly 100 is removed from the base assembly 200 and placed alone on the desktop, the magnetic ring assembly 120 moves upward to the second position under the action of the gravity of the water tank 110 and the supporting force of the desktop. At this time, the elastic member 124 is compressed, and the lower end of the magnetic ring fixing seat 122 is flush with the lower end of the protruding structure 111, which facilitates the stable placement of the water tank assembly 100.

[0073] The present embodiment provides a water tank assembly 100, comprising a water tank 110 and a protruding structure 111 provided at the bottom of the water tank 110. A magnetic ring assembly 120 as in any one of the schemes in Embodiments 1 to 3 is also installed at the bottom of the water tank 110. The magnetic ring assembly 120 has a first position away from the bottom of the water tank 110 and a second position close to the bottom of the water tank 110. When the magnetic ring assembly 120 is forced to move to the first position, the detection assembly 220 in the base 210 can pass through the first through hole 1221 and the second through hole 1231 in sequence to detect the position of the magnetic ring 123; when the magnetic ring assembly 120 is forced to move to the second position, the lower end of the magnetic ring fixing seat 122 is flush with the lower end of the protruding structure 111.
