Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a humidifier. Background Technology

[0002] A mist-free humidifier increases air humidity without producing visible water mist. This reduces water mist buildup on furniture, decreases bacterial growth, and prevents potential damage to furniture and floors from water mist deposits.

[0003] In related technologies, a mist-free humidifier includes a water tank, a float bottle installed inside the water tank, and a water shortage switch. The water shortage switch is located outside the water tank and is connected to the float bottle via a linkage mechanism. The float bottle can float up and down in the water tank as the water level changes. When the water tank is short of water, the float bottle moves downward to trigger the water shortage switch via the linkage.

[0004] However, among related technologies, humidifiers have poor structural compactness and high cost. Utility Model Content

[0005] In view of the above problems, this application provides a humidifier that automatically shuts off the humidifier main unit when it is short of water, while improving the humidifier's structural compactness and reducing costs.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] This application provides a humidifier, including:

[0008] Humidifier main unit;

[0009] A filter element assembly is installed on the humidifier main unit. The filter element assembly includes a filter element and a water storage tray disposed below the filter element. The water storage tray has a water storage tank.

[0010] A floating element is disposed in the water storage tank. The floating element is configured to float up and down between a first position and a second position as the height of the liquid level in the water storage tank changes. The end of the floating element facing the water storage tank has a clearance groove.

[0011] A water shortage switch is located within the clearance groove. When the floating component switches between the first position and the second position, the water shortage switch is triggered or detrimentalized to turn the humidifier main unit off or on.

[0012] The humidifier provided by the embodiments of the present application is provided with a water shortage switch, and the water shortage switch is arranged in the avoiding groove on the floating member. When the floating member floats up and down between the first position and the second position with the change of the liquid level in the water storage tank, the water shortage switch can be triggered or untriggered to turn off or turn on the humidifier host, so as to achieve the purpose of water shortage protection of the humidifier. Meanwhile, the water shortage switch is arranged in the avoiding groove on the floating member, so that the compactness of the structure of the humidifier as a whole can be improved, the overall volume of the humidifier can be reduced, and the structure is simple, so that the purpose of reducing the cost can be achieved.

[0013] In some embodiments, the water shortage switch is mounted on one of the water storage disc and the groove bottom of the avoiding groove, and the other of the water storage disc and the groove bottom of the avoiding groove is provided with a triggering part. When the triggering part triggers the water shortage switch, the water shortage switch turns off the humidifier host.

[0014] In this way, when the floating member floats up and down between the first position and the second position with the change of the liquid level in the water storage tank, the water shortage switch can be triggered or untriggered by the triggering part, so as to achieve the purpose of water shortage protection.

[0015] In some embodiments, the water storage disc has a mounting base, the water shortage switch is mounted on the mounting base, the floating member is configured to surround the outer circumferential side of the mounting base, the groove bottom of the avoiding groove is formed as the triggering part, and when the floating member descends from the first position to the second position, the groove bottom of the avoiding groove is configured to trigger the water shortage switch to turn off the humidifier host.

[0016] In this way, the water shortage switch can be prevented from being in contact with the water in the water storage tank, so as to improve the safety and reliability of the water shortage switch.

[0017] In some embodiments, the mounting base has a mounting boss, the mounting boss has a mounting cavity, the water shortage switch has a switch part, the water shortage switch is mounted in the mounting cavity, and the switch part protrudes outward from the top of the mounting cavity. When the groove bottom of the avoiding groove triggers the switch part, the humidifier host is turned off.

[0018] In this way, the protection of the water shortage switch can be further improved by the mounting boss, and the service life of the water shortage switch can be prolonged.

[0019] In some embodiments, the cavity wall of the mounting cavity has a first guide structure, the water shortage switch has a second guide structure matched with the first guide structure, and when the water shortage switch is mounted in the mounting cavity, the second guide structure is configured to move along the second guide structure.

[0020] In this way, the water shortage switch can be installed into the installation cavity smoothly and accurately.

[0021] In some embodiments, the first guide structure is a first guide plane, and the second guide structure is a second guide plane matched with the first guide plane.

[0022] In this way, the first guide structure and the second guide structure are simple in structure, easy to implement, and low in cost.

[0023] In some embodiments, the first guide structure includes one of a guide protrusion and a guide groove, and the second guide structure includes the other of the guide protrusion and the guide groove.

[0024] In this way, the installation accuracy of the water shortage switch can be improved, and the first guide structure and the second guide structure are simple in structure, easy to implement, and low in cost.

[0025] In some embodiments, the humidifier main machine has a motor, and the installation base has a space for avoiding the motor on a side away from the water shortage switch. The motor is located in the space for avoiding and connected to the water shortage switch. The water shortage switch is configured to control the opening and closing of the motor.

[0026] In this way, the structure of the humidifier can be further compact, the space utilization rate can be improved, and the overall volume of the humidifier can be reduced.

[0027] In some embodiments, the installation base has a first guide portion, and the floating member has a second guide portion matched with the first guide portion. When the floating member floats up and down with the change of the liquid level in the water storage tank, the floating member moves along the first guide portion through the second guide portion.

[0028] In this way, the floating route of the floating member can be improved in accuracy, so that the accuracy of triggering the water shortage switch can be improved, and the reliability of the water shortage protection can be improved.

[0029] In some embodiments, the first guide portion is one of a guide column and a guide hole, and the second guide portion is the other of the guide column and the guide hole.

[0030] In this way, the first guide portion and the second guide portion are simple in structure, easy to implement, and low in cost.

[0031] In some embodiments, a limiting member is further included. The limiting member is detachably connected with the first guide portion. When the floating member is floated from the second position to the first position, a part of the upper surface of the floating member abuts against the limiting member.

[0032] Therefore, the floating part is prevented from falling off, the position reliability of the floating part is improved, the disassembly difficulty of the floating part is reduced, and the user experience is improved.

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. The embodiments below and the features in the embodiments can be combined with each other without conflict.

[0056] Please refer to Figure 1As shown, the embodiment of the present application provides a humidifier 10, which can be a fog-free humidifier 10. The fog-free humidifier 10 generally comprises a humidifier main machine 100, a filter core assembly 200 and a water tank 300. The filter core assembly 200 is arranged between the humidifier main machine 100 and the water tank 300. The filter core assembly 200 comprises a filter core 210. The water tank 300 is used for storing water for humidification of the humidifier 10. The water in the water tank 300 is used for humidifying the filter core 210. The humidifier main machine 100 comprises a main machine shell, a motor 110 and an air fan 120. The main machine shell has a containing cavity. The motor 110 and the air fan 120 are located in the containing cavity. The air fan 120 is connected with the output shaft of the motor 110. The motor 110 is used for driving the air fan 120 to operate. In this way, the air fan 120 can drive the air to flow and make the flowing air flow pass through the humidified filter core 210, so that the moisture on the filter core 210 is naturally evaporated into the air, thereby increasing the humidity of the air in a manner of not generating visible water mist, reducing the deposition of visible water mist on furniture, reducing the breeding of bacteria, and also avoiding the potential damage of water mist deposition to furniture and floor.

[0057] The water in the water tank 300 can be pure water or a water solution with additives such as mixed spices, bactericides and essential oils. The embodiment of the present application does not make specific limitation on this. The liquid used for humidifying the filter core 210 is collectively referred to as water, and will not be specifically described below.

[0058] In some embodiments, please refer to Figure 1 As shown, the water tank 300 is arranged above the humidifier main machine 100. The filter core assembly 200 is arranged between the humidifier main machine 100 and the water tank 300. The bottom of the water tank 300 has a lower water hole which can be opened and closed. When the lower water hole is opened, the water in the water tank 300 can drip through the lower water hole to the filter core 210. In this way, it is not necessary to additionally arrange a water pump to pump the water in the water tank 300 to the filter core 210, thereby reducing the parts of the whole machine and reducing the cost.

[0059] In some embodiments, the filter core assembly 200 further comprises an air outlet piece 260. The air outlet piece 260 has a wind blocking part 261. The wind blocking part 261 is arranged to form a liquid containing groove 262. The filter core 210 is arranged on the outer circumferential side of the wind blocking part 261. The side wall of the liquid containing groove 262 has a water outlet along the circumference. The water in the water tank 300 drips through the lower water hole to the liquid containing groove 262. The water in the liquid containing groove 262 wets the filter core 210 through the water outlets around the liquid containing groove 262, thereby improving the uniformity of the wetting of the filter core 210.

[0060] In order to avoid the water on the filter core 210 flowing into the humidifier main machine 100, in the embodiment of the present application, please refer to Figures 2 to 7As shown, the filter core assembly 200 further comprises a water storage tray 220, which is arranged below the filter core 210 and is installed in the accommodating cavity of the main machine housing, and is located above the motor 110 and the fan 120. The water storage tray 220 has a water storage groove 221, and the lower end of the filter core 210 has a submerged part located in the water storage groove 221. In this way, the water on the filter core 210 sinks through the submerged part and accumulates in the water storage groove 221. Thus, the water on the filter core 210 can be prevented from flowing into the humidifier main machine 100 to affect the performance of the humidifier main machine 100, thereby improving the working reliability of the humidifier 10.

[0061] In some embodiments, the water storage tray 220 further has an air outlet grille 225, which is arranged around the outer circumferential side of the water storage groove 221. The side wall of the main machine housing has an air inlet hole 130. In this way, when the motor 110 drives the fan 120 to operate, the air entering through the air inlet hole 130 is blown to the filter core 210 by the fan 120, so that the airflow passes through the filter core 210, and the water on the filter core 210 is naturally evaporated, thereby achieving the purpose of humidifying the air.

[0062] In some embodiments, a switch valve 270 is arranged in the drain hole. The valve rod 271 is arranged in the drain hole. One end of the valve rod 271 located in the water tank 300 has a blocking part 272. The valve rod 271 can move in the drain hole to block or move away from the drain hole with the blocking part 272, so as to close or open the drain hole through the blocking part 272.

[0063] In some embodiments, the humidifier 10 further comprises a floating member 240 arranged in the water storage groove 221. In this way, the floating member 240 can float up and down between a first position and a second position according to the change of the liquid level (water surface) in the water storage groove 221. The first position is, for example, the highest position that the floating member 240 can reach in the water storage groove 221. The second position is that there is no water or insufficient water in the water storage groove 221, so that the generated buoyancy is not enough to make the floating member 240 float on the water surface. In addition, the humidifier 10 further comprises a driving mechanism configured to drive the movement of the valve rod 271 in the drain hole. Exemplarily, the driving mechanism comprises a lifting rod 280 and a connecting rod connected with the lifting rod 280. The lifting rod 280 penetrates the bottom wall of the liquid containing groove 262 and is connected with the valve rod 271. The first end of the connecting rod is connected with the end of the lifting rod 280 away from the valve rod 271. The second end of the connecting rod is arranged on the floating member 240. The side wall of the connecting rod is provided with a rotating shaft. The outer bottom wall of the liquid containing groove 262 has a boss. The connecting rod is rotationally connected with the boss through the rotating shaft.

[0064] In addition, the valve rod 271 has a limiting portion at the end away from the blocking portion 272, and a first elastic member is arranged between the limiting portion and the outer bottom wall of the water tank 300, and the first elastic member includes but is not limited to a spring; the top rod 280 has a first limiting structure at the end towards the valve rod 271, and the valve rod 271 has a second limiting structure at the end towards the connecting rod, and a second elastic member is arranged between the first limiting structure and the inner bottom wall of the liquid containing groove 262, and the second elastic member includes but is not limited to a spring.

[0065] When the water in the water storage groove 221 is insufficient to float the floating member 240, the connecting rod drives the valve rod 271 to move upward through the top rod 280, at this time, the blocking portion 272 opens the water outlet hole, so that the water in the water tank 300 drops into the liquid containing groove 262 through the water outlet hole, and the water in the liquid containing groove 262 flows into the filter core 210 through the four water outlets, and the excess water on the filter core 210 flows along the filter core 210 into the water storage groove 221, and as the water level in the water storage groove 221 rises, the floating member 240 moves upward, and when the upper end of the floating member 240 contacts the second end of the connecting rod, the connecting rod rotates around the rotating shaft, so that the connecting rod drives the valve rod 271 to move downward along the vertical direction through the top rod 280, and when the water level in the water tank 300 reaches a certain height, the blocking portion 272 blocks the water outlet hole, at this time, the first elastic member is in a free state, and the second elastic member is in a compressed state, and the valve rod 271 is driven to move to one side of the top rod 280 under the elastic force of the first elastic member, so as to improve the connection tightness between the blocking portion 272 and the water outlet hole, thereby improving the sealing performance of the water outlet hole, and the water tank 300 temporarily stops discharging water through the water outlet hole, and the fan 120 is driven by the motor 110 to drive air flow to blow towards the filter core 210 through the air outlet grille 225, so that the moisture on the filter core 210 is naturally evaporated into the air under the action of the air flow, thereby humidifying the air.

[0066] The blocking portion 272 can be a blocking structure formed by rubber, plastic or the like having a sealing function, and can realize the function of blocking and sealing the water outlet hole; for example, the blocking portion 272 can be sleeved on the end of the valve rod 271, so as to facilitate replacement of the blocking portion 272.

[0067] As the moisture evaporates and other factors, the water level in the water storage groove 221 decreases, and the floating member 240 moves downward as the water level in the water storage groove 221 decreases, at this time, the second end of the connecting rod is in a free state, the second elastic member is driven to move upward through the first limiting structure under the elastic force of the second elastic member, thereby driving the valve rod 271 to move upward through the top rod 280, so that the blocking portion 272 contacts the water outlet hole, and the water in the water tank 300 continues to drop downward through the water outlet hole, so as to improve the humidity of the filter core 210.

[0068] The floating member 240 includes but is not limited to a floating bottle, and the floating bottle is a hollow structure with an open bottom.

[0069] In some embodiments, referring to Figures 2 to 6 The humidifier main machine 100 further comprises a water shortage switch 230, and the floating element 240 has an avoiding groove 241 at one end facing the water storage tank 221; the water shortage switch 230 is located in the avoiding groove 241, and when the floating element 240 switches between the first position and the second position, the water shortage switch 230 is triggered or untriggered to turn off or turn on the humidifier main machine 100 through the water shortage switch 230.

[0070] For example, the water shortage switch 230 can realize the function of turning off the humidifier main machine 100 when there is a water shortage, for example, when the floating element 240 moves upward with the rising of the water level in the water storage tank 221, at this time, the water shortage switch 230 is not triggered, and the humidifier main machine 100 is in a powered-on state, and the motor 110 and the fan 120 in the humidifier main machine 100 can normally operate; when the floating element 240 moves downward with the falling of the water level in the water storage tank 221 until the water level in the water storage tank 221 reaches the lowest position (i.e. the position where the floating element 240 cannot continue to move downward), that is, the water storage tank 221 is in a water shortage state, at this time, the water shortage switch 230 is triggered, and the humidifier main machine 100 is in a powered-off state, and the motor 110 and the fan 120 cannot be started, so as to realize the function of water shortage shutdown of the humidifier main machine 100, thereby improving the water shortage protection of the humidifier 10; and by arranging the water shortage switch 230 in the water storage tank 221 of the floating element 240, the space can be saved, and the compactness of the overall structure of the humidifier 10 is improved.

[0071] Therefore, in the embodiments of the present application, by arranging a water shortage switch 230 and arranging the water shortage switch 230 in the avoiding groove 241 on the floating element 240, when the floating element 240 floats up and down between the first position and the second position with the change of the liquid level in the water storage tank 221, the water shortage switch 230 can be triggered or untriggered to turn off or turn on the humidifier main machine 100 through the water shortage switch 230, thereby realizing the purpose of water shortage protection of the humidifier 10, and at the same time, by arranging the water shortage switch 230 in the avoiding groove 241 of the floating element 240, the compactness of the overall structure of the humidifier 10 can be improved, the overall volume of the humidifier 10 can be reduced, and the structure is simple, thereby achieving the purpose of reducing the cost.

[0072] In some embodiments, the water shortage switch 230 is mounted on one of the water storage tray 220 and the groove bottom of the avoiding groove 241, and the other is provided with a trigger part, when the trigger part triggers the water shortage switch 230, the water shortage switch 230 closes the humidifier host 100, so that the floating piece 240 can trigger or release the trigger of the water shortage switch 230 when it floats up and down between the first position and the second position with the change of the liquid level in the water storage tank 221, in order to achieve the purpose of water shortage protection.

[0073] For example, as shown in Figures 2 to 7 , the water storage tray 220 has a mounting base 222, the water shortage switch 230 is mounted on the mounting base 222, the floating piece 240 is configured to surround the outer circumferential side of the mounting base 222, and the groove bottom of the avoiding groove 241 is formed as a trigger part, when the floating piece 240 is lowered from the first position to the second position, the groove bottom of the avoiding groove 241 triggers the water shortage switch 230 to close the humidifier host 100, that is, the humidifier host 100 is in a power-off state, so that the humidifier host 100 is in a water shortage shutdown state; in addition, by mounting the water shortage switch 230 on the mounting base 222, for example, as shown in Figure 7 , the mounting base 222 is a convex structure with a certain height, so that the water shortage switch 230 can be prevented from being in contact with the water in the water storage tank 221, thereby improving the safety and reliability of the water shortage switch 230.

[0074] In some embodiments, as shown in Figures 2 to 6 , the mounting base 222 has a mounting boss 223, the mounting boss 223 has a mounting cavity 224, the water shortage switch 230 has a switch part 231, the water shortage switch 230 is mounted in the mounting cavity 224, and the switch part 231 protrudes outward from the top of the mounting cavity 224, when the floating piece 240 is lowered to the second position, the groove bottom of the avoiding groove 241 triggers the switch part 231 to close the humidifier host 100, so that the humidifier host 100 is in a power-off shutdown state; when the floating piece 240 rises to the first position, the groove bottom of the floating piece 240 releases the trigger of the switch part 231, and the humidifier host 100 is in a power-on state, so that the humidifier host 100 can operate normally; in addition, by providing the mounting boss 223, the height of the water shortage switch 230 can be further increased to prevent the water shortage switch 230 from being in contact with the water in the water tank, and by providing the mounting cavity 224 on the mounting boss 223, the water shortage switch 230 is arranged in the mounting cavity 224, which can prevent accidental touching or damage to the water shortage switch 230 and prolong the service life of the water shortage switch 230.

[0075] Among them, the switch part 231 can move in the vertical direction to realize the on-off of the motor; for example, as shown in Figure 2 and Figure 3As shown in FIG. 13, the switch part 231 is in a free state, i.e. not triggered by the float 240, at this time, the motor 110 is in an energized state; while in Figure 4 and Figure 5 As shown in FIG. 13, the switch part 231 is in a free state, i.e. not triggered by the float 240, at this time, the motor 110 is in an energized state; while in

[0076] In some embodiments, the cavity wall of the mounting cavity 224 has a first guide structure 2241, and the water shortage switch 230 has a second guide structure 232 matched with the first guide structure 2241, when the water shortage switch 230 is mounted in the mounting cavity 224, the second guide structure 232 is configured to move along the second guide structure 232, which can improve the smoothness and accuracy of the installation position when the water shortage switch 230 is mounted in the mounting cavity 224.

[0077] An exemplary, please refer to Figure 8 As shown in FIG. 13, the switch part 231 is in a free state, i.e. not triggered by the float 240, at this time, the motor 110 is in an energized state; while in

[0078] In some embodiments, the cavity wall of the mounting cavity 224 has a first guide structure 2241, and the water shortage switch 230 has a second guide structure 232 matched with the first guide structure 2241, when the water shortage switch 230 is mounted in the mounting cavity 224, the second guide structure 232 is configured to move along the second guide structure 232, which can improve the smoothness and accuracy of the installation position when the water shortage switch 230 is mounted in the mounting cavity 224.

[0079] Another exemplary, the first guide structure 2241 includes one of a guide protrusion and a guide groove, and the second guide structure 232 includes the other one of the guide protrusion and the guide groove, in this way, the guide protrusion can move along the extension direction of the guide groove, thereby improving the installation accuracy of the water shortage switch 230, while the structure of the first guide structure 2241 and the second guide structure 232 is simple, easy to implement, and low in cost.

[0080] In some embodiments, please refer to Figures 2 to 5As shown, the side of the mounting base 222 away from the water shortage switch 230 has a space 2221, and the motor 110 is located in the space 2221 and connected with the water shortage switch 230, which is configured to control the opening and closing of the motor 110. In this way, the compactness of the humidifier 10 can be further improved, the space utilization can be improved, and the overall volume of the humidifier 10 can be reduced.

[0081] In some embodiments, the mounting base 222 has a first guide part 226, and the floating member 240 has a second guide part 242 matched with the first guide part 226. When the floating member 240 floats up and down with the change of the liquid level in the water storage tank 221, the floating member 240 moves along the first guide part 226 through the second guide part 242. In this way, the floating route of the floating member 240 can be improved, and the accuracy of triggering the water shortage switch 230 can be improved, thereby improving the reliability of the water shortage protection.

[0082] In some embodiments, the first guide part 226 is one of a guide column and a guide hole, and the second guide part 242 is the other one of the guide column and the guide hole.

[0083] For example, as shown in Figures 2 to 7 In some embodiments, the first guide part 226 is a guide column, and the second guide part 242 is a guide hole matched with the guide column. In this way, when the floating member 240 moves up and down along the vertical direction, the floating member 240 moves along the extension direction of the guide column, thereby improving the accuracy of the route of the floating member 240 when floating up and down. In addition, the first guide part 226 and the second guide part 242 have simple structure, are easy to implement, and have low cost.

[0084] In some embodiments, as shown in Figures 2 to 7 In some embodiments, the mounting base 222 has a first guide part 226, and the floating member 240 has a second guide part 242 matched with the first guide part 226. When the floating member 240 floats up and down with the change of the liquid level in the water storage tank 221, the floating member 240 moves along the first guide part 226 through the second guide part 242. In this way, the floating route of the floating member 240 can be improved, and the accuracy of triggering the water shortage switch 230 can be improved, thereby improving the reliability of the water shortage protection.

[0085] In some embodiments, the first guide part 226 is one of a guide column and a guide hole, and the second guide part 242 is the other one of the guide column and the guide hole.

[0086] In summary, the humidifier provided by the embodiments of the present application sets a water shortage switch, and sets the water shortage switch in the avoiding groove on the floating member. When the floating member floats up and down between the first position and the second position with the change of the liquid level in the water storage groove, the water shortage switch can be triggered or untriggered to close or open the humidifier host through the water shortage switch, so as to achieve the purpose of water shortage protection of the humidifier. At the same time, by setting the water shortage switch in the avoiding groove of the floating member, the compactness of the overall structure of the humidifier can be improved, the overall volume of the humidifier can be reduced, and the structure is simple, thereby achieving the purpose of reducing the cost.
