Description

Technical Field

[0001] The present application relates to the field of humidifiers, and in particular to a humidifier. Background Art

[0002] The humidifier assembly is a key component within the humidifier. When the humidifier is operating, air flows through it, humidifying the air. The humidifier typically consists of a water container and a filter, which is inserted into the water container. During operation, a certain amount of water accumulates in the water container, which the filter absorbs, becoming wet. The airflow is humidified as it passes through the filter.

[0003] The humidifier is also provided with a water level detection component, which is located outside the water container and detects the water level detection area near the water level detection component in the water container to determine the water level in the water container. The water level detection component is usually based on capacitance for detection. When the water level in the water level detection area is high, the capacitance value detected by the water level detection component is large. When the water level in the water level detection area is low, the capacitance value detected by the water level detection component is small. Since the filter has a relatively strong water absorption capacity, when the water level in the water container is relatively low, there is still a lot of water in the filter. The water in the filter is more likely to affect the detection of the water level detection component, so that when the water level in the water container is already relatively low, the water level detection component still detects a relatively large capacitance value, making it impossible to detect the actual water level. Utility Model Content

[0004] The embodiment of the present application provides a humidifier that can accurately detect the water level. The technical solution is as follows:

[0005] An embodiment of the present application provides a humidifier, which includes a water container, a filter and a water level detection component. The water container has a water tank, and the water tank has at least one water level detection area. The first end of the filter is inserted into the water tank, and the filter is located outside the water level detection area. The water level detection component is located outside the water tank and is used to detect the water level in the water level detection area.

[0006] In some examples, the first end of the filter has a notch, and the notch is located in the water level detection area.

[0007] In some examples, the filter screen includes at least two sub-filter screens, the at least two sub-filter screens are arranged sequentially along the water tank, and the water level detection area is located between adjacent sub-filter screens.

[0008] In some examples, the width of the water tank in the water level detection area is smaller than the width of the area outside the water level detection area.

[0009] In some examples, the width of the water tank in the water level detection area is not less than 8 mm.

[0010] In some examples, the water container includes an inner plate, an outer plate, and a bottom plate, the outer plate is sleeved outside the inner plate, the bottom plate is located between the inner plate and the outer plate, and the inner plate, the outer plate, and the bottom plate form the water tank.

[0011] In some examples, in the water level detection area, at least one of the following has a recessed portion:

[0012] the outer side plate;

[0013] The inner side panel.

[0014] In some examples, the recessed portion is lower than a side of the outer plate away from the bottom plate.

[0015] As an example, the inner plate and the outer plate are both cylindrical, and the bottom plate is annular.

[0016] In some examples, the water tank has multiple water level detection areas, and the multiple water level detection areas are arranged at equal intervals.

[0017] Optionally, the humidifier further includes a water separation tray, which is arranged opposite to the second end of the filter and connected to the water container.

[0018] In some examples, the water level detection component is located at one of the following locations:

[0019] the inner side of the water container;

[0020] the outer side of the water container;

[0021] The water container is located away from the side of the opening of the water tank.

[0022] The beneficial effects of the technical solutions provided in the embodiments of the present application include at least:

[0023] By inserting the first end of the filter into the water tank of the water container, the filter can absorb water from the water tank. Since the filter is located outside the water level detection area of ​​the water tank, and the water level detection member is located outside the water tank and is used to detect the water level in the water level detection area, the water in the filter will not affect the accuracy of the water level detection in the water level detection area, thereby making the water level detection result more accurate.

[0043] Figure 1 This is a schematic diagram of the structure of a humidifier provided in an embodiment of the present application. Figure 1As shown, the humidifier includes an air inlet housing 11, an air outlet housing 12, and a water tank assembly 40. The air outlet housing 12 is located on top of the air inlet housing 11, and the air outlet housing 12 and the air inlet housing 11 are connected to form a receiving cavity. The water tank assembly 40 is located on top of the air outlet housing 12.

[0044] Figure 2 This is a structural diagram of a humidifier provided in an embodiment of the present application. Figure 2 At least the air inlet housing 11 is omitted. Figure 2 As shown, the humidifier also includes an inner housing 21, a fan 22, and a humidifying assembly 30. The inner housing 21 is located in the accommodating chamber enclosed by the air inlet housing 11 and the air outlet housing 12. The inner housing 21 is connected to at least one of the air inlet housing 11 and the air outlet housing 12, dividing the accommodating chamber into a lower chamber and an upper chamber. A filter 111 may also be provided in the lower chamber. The fan 22 is located in the inner housing 21. The humidifying assembly 30 is located in the upper chamber.

[0045] When the humidifier is in operation, the fan 22 runs, and air is sucked into the lower cavity from the air inlet housing 11, and then enters the upper cavity through the inner housing 21. The air is humidified in the upper cavity under the action of the humidifying assembly 30, and finally discharged from the air outlet housing 12.

[0046] Figure 3 This is a schematic diagram of the structure of a humidifying component provided in an embodiment of the present application. Figure 3 As shown, the humidifying assembly 30 includes a water container 31 and a filter 32 , and the water container 31 has a water tank 31 a.

[0047] As an example, the water tank 31a may be annular and the filter screen 32 may be cylindrical. The annular shape here may refer to a shape formed by a closed shape and another closed shape located inside the closed shape, including but not limited to a circular ring, an elliptical ring, and a polygonal frame.

[0048] In the embodiment of the present application, a circular water tank 31a is used as an example. The water tank 31a has at least one water level detection area 31b. The first end of the filter 32 is inserted into the water tank 31a, and the filter 32 is located outside the water level detection area 31b. The filter 32 has a first end and a second end opposite to each other, with the second end located outside the water tank 31a.

[0049] In order to better show the water tank 31a, Figure 3 The water container 31 and the filter screen 32 are separated.

[0050] Figure 4 This is a schematic diagram of the assembly of a humidifying component provided in an embodiment of the present application. Figure 4As shown, the humidifier also includes a water level detection member 50, which is located outside the water tank 31a and is used to detect the water level in the water level detection area 31b. The water level detection member 50 is arranged adjacent to the water level detection area 31b so that the water level in the water level detection area 31b can be detected based on the capacitance.

[0051] In the embodiment of the present application, since the filter 32 is located outside the water level detection area 31b of the water tank 31a, and the water level detection component 50 is located outside the water tank 31a, the water level detection component 50 is used to detect the water level in the water level detection area 31b. Therefore, the water in the filter 32 will not affect the accuracy of the water level detection in the water level detection area 31b, making the water level detection result more accurate.

[0052] As an example, the water container 31 and the filter 32 are both annular and can be sleeved on the outer surface of the inner housing 21. The inner housing 21 has an air inlet and an air outlet. The air inlet is located at the bottom of the inner housing 21, and the air outlet is located on the side wall of the inner housing 21 and faces the filter 32.

[0053] The humidifying assembly 30 further includes a water diversion tray 33, which is located at the top of the inner housing 21 and is arranged opposite the second end of the filter 32. A plurality of water diversion holes 33a are distributed along the edge of the water diversion tray 33, and the water diversion holes 33a are directly opposite the second end of the filter 32.

[0054] Exemplarily, the water diversion tray 33 can be detachably connected to the water container 31 via a buckle, and the filter screen 32 is arranged between the water diversion tray 33 and the water container 31 .

[0055] like Figure 4 As shown, the edge of the water diversion tray 33 can be connected to a first connection portion 331, and the edge of the water container 31 can be connected to a second connection portion 314. The first connection portion 331 and the second connection portion 314 are detachably connected. As an example, the first connection portion 331 can be a buckle, and the second connection portion 314 can have a slot 312b. The buckle and the slot 312b are detachably connected, and the slot 312b can extend to the outer wall of the water container 31. The portion of the outer wall of the water container 31 corresponding to the slot 312b can be recessed into the water tank 31a, so that the slot 312b has sufficient depth to accommodate the buckle.

[0056] like Figure 2 As shown, the water tank assembly 40 includes a water tank 41 and a drain valve 42. The bottom of the water tank 41 is connected to the air outlet housing 12. The drain valve 42 connects the water tank 41 and the humidification assembly 30 located within the air outlet housing 12. For example, the water outlet of the drain valve 42 can face the water diversion tray 33. An electromagnet 23 is also provided in the inner housing 21. The electromagnet 23 is used to trigger the drain valve 42 and control the opening and closing of the drain valve 42.

[0057] During operation of the humidifier, the water tank 41 is used to supply water to the humidifying assembly 30. When the water level in the water tank 31a is lower than a preset value, it indicates that the amount of water in the humidifying assembly 30 is insufficient and water needs to be added to the water tank 31a. When the water level in the water tank 31a is lower than the preset value, the electromagnet 23 triggers the drain valve 42, causing the drain valve 42 to be turned on. The water stored in the water tank 41 flows through the drain valve 42 into the upper cavity, then flows through the water diversion hole 33a of the water diversion plate 33 into the filter 32, and then flows into the water tank 31a through the filter 32. After the water level in the water tank 31a rises to no less than the preset value, the drain valve 42 closes.

[0058] In some examples, the humidifier may further include a water pump connecting the water tank 41 and the humidifying assembly 30. During operation, the water pump pumps water from the water tank 41 and delivers it to the water distribution tray 33 of the humidifying assembly 30. In these examples, the use of the water pump allows for greater flexibility in the placement of the water tank 41. For example, the water tank 41 can be placed at the bottom of the air inlet housing 11 to lower the center of gravity of the humidifier and reduce the risk of the humidifier tipping over.

[0059] Figure 5 This is a schematic diagram of the structure of a water level detection component provided in an embodiment of the present application. Figure 5 As shown, the water level detecting member 50 may include a printed circuit board 51 and a water detecting chip 52 located on the printed circuit board 51. The water detecting chip 52 is arranged facing the water level detecting area 31b of the water tank 31a.

[0060] As an example, in an embodiment of the present application, the water level detection component 50 is located on the outside of the water holding component 31. In other possible implementations, the water level detection component 50 may also be located on the inside of the water holding component 31, or on the side of the water holding component 31 away from the opening of the water tank 31a, that is, at the bottom of the water holding component 31.

[0061] The water container 31 is annular in shape. The outer side of the water container 31 refers to the side of the water container 31 away from the center of the ring, and the inner side of the water container 31 refers to the side of the water container 31 closer to the center of the ring. When the water level detector 50 is arranged on the inner or outer side of the water container 31, water adhering to the sidewalls of the water trough 31a will fall to the bottom of the water trough 31a under the action of gravity. This can reduce the impact of water adhering to the sidewalls of the water trough 31a on the detection results, thereby improving the accuracy of the detection results.

[0062] like Figure 3 As shown, the first end of the filter screen 32 has a notch 32 a , and the notch 32 a is located in the water level detection area 31 b .

[0063] In the embodiment of the present application, a gap 32 a is provided at the first end of the filter 32 , and the gap 32 a is used to avoid the water level detection area 31 b , thereby preventing the water in the filter 32 from affecting the accuracy of the detection result of the water level detection component 50 .

[0064] In addition, the part of the filter 32 located above the notch 32a can still humidify the air, that is, the notch 32a is on the side away from the bottom of the water tank 31a, and the integrity of the filter 32 is not destroyed. It can still humidify the air flowing through, preventing the air from flowing out of the humidification component 30 without being humidified, so that the humidifier has a higher efficiency in humidifying the air.

[0065] like Figure 3 As shown, the width of the water tank 31a in the water level detection area 31b is smaller than the width of the area outside the water level detection area 31b.

[0066] The width of the water tank 31a refers to the distance between the inner wall and the outer wall of the water tank 31a. In the embodiment of the present application, the width of the water tank 31a is smaller in the water level detection area 31b, and the width of the water tank 31a is larger outside the water level detection area 31b.

[0067] The water level detector 50 determines the water level by detecting the capacitance of the water level detection area 31b. In the water level detection area 31b, the width of the water tank 31a has a certain impact on the detection accuracy of the water level detector 50. A smaller width is more conducive to detecting the capacitance, thereby more accurately determining the water level in the water tank 31a.

[0068] In the embodiment of the present application, the width of the water tank 31a in the water level detection area 31b is not less than 8 mm.

[0069] If the width of the water trough 31a in the water level detection area 31b is too small, it may also affect the accuracy of water level detection. When the width is too small, a water film may form between the two opposing walls of the water trough 31a in the water level detection area 31b due to water adhesion. This water film can cause the detected water level to be higher than the actual water level. Setting the width of the water trough 31a in the water level detection area 31b to be no less than 8mm can prevent the formation of a water film and affect the accuracy of detection results.

[0070] As an example, the width of the water tank 31a in the water level detection area 31b can be 8mm to 15mm, and the width of the area outside the water level detection area 31b can be 20mm to 40mm. For example, the width of the water tank 31a in the water level detection area 31b is 10mm, and the width of the area outside the water level detection area 31b is 25mm.

[0071] Figure 6 This is a schematic diagram of the structure of a water container provided in an embodiment of the present application. Figure 6As shown, the water container 31 includes an inner plate 311, an outer plate 312, and a bottom plate 313. The outer plate 312 is positioned over the inner plate 311, and the bottom plate 313 is positioned between the inner and outer plates 311 and 312. The inner and outer plates 311, 312, and bottom plate 313 form a water tank 31a. The inner edge of the bottom plate 313 can be connected to the inner plate 311, and the outer edge of the bottom plate 313 can be connected to the outer plate 312.

[0072] The water container 31 has a simple structure and is easy to manufacture. For example, it can be directly manufactured by injection molding. By adjusting the shape of the inner plate 311 or the outer plate 312, the width of the water tank 31a in the water level detection area 31b can be made smaller than the width of the area outside the water level detection area 31b.

[0073] In this example, the inner plate 311 and the outer plate 312 are both cylindrical, and the bottom plate 313 is annular, thereby forming a circular water tank 31a. This allows the air sent into the humidifying assembly 30 by the fan 22 to be blown out of the humidifying assembly 30 more evenly in multiple directions in the circumferential direction.

[0074] In other possible implementations, the inner plate 311 and the outer plate 312 may also be in the shape of a square tube, for example, a square tube with a quadrilateral cross section, a square tube with a pentagonal cross section, etc.

[0075] As an example, in the embodiment of the present application, in the water level detection area 31 b , the outer plate 312 has a recessed portion 312 a , and the recessed portion 312 a is located in the water level detection area 31 b .

[0076] In the embodiment of the present application, a recessed portion 312 a is provided on the outer plate 312 , so that the width of the water tank 31 a in the water level detection area 31 b is smaller than the width of the area outside the water level detection area 31 b .

[0077] In addition, the recessed portion 312a can also be used to accommodate the water level detection component 50, so as to make the internal structure layout of the humidifier more compact.

[0078] like Figure 6 As shown, the recessed portion 312a is lower than the side of the outer plate 312 away from the bottom plate 313. That is, the recessed portion 312a is not located at the side of the outer plate 312 away from the bottom plate 313, and the side of the outer plate 312 away from the bottom plate 313 is not recessed into the water tank 31a. The distance between the side of the outer plate 312 away from the bottom plate 313 and the recessed portion 312a is greater than 0.

[0079] This enables the recessed portion 312a to be used to support the filter screen 32, and the outer plate 312 is higher than the recessed portion 312a, and the higher portion can also block water flowing into the recessed portion 312a, preventing water from overflowing from the recessed portion 312a.

[0080] In the embodiment of the present application, the water tank 31a has two water level detection areas 31b, and the two water level detection areas 31b are arranged at equal angles along the circumference, that is, the two water level detection areas 31b are arranged at an interval of 180°.

[0081] Correspondingly, in the humidifier, two water level detection members 50 are provided, and the water level detection members 50 are provided in a one-to-one correspondence with the water level detection areas 31 b.

[0082] When the humidifier is tilted, the water tank 31a will be tilted, and the water level will be different at different locations in the water tank 31a. In this embodiment of the present application, by providing two water level detection areas 31b, the water level is detected from two locations in the water tank 31a, thereby more accurately determining the amount of water remaining in the water tank 31a.

[0083] For example, the average value of the water levels in the two water level detection areas 31 b may be used as the actual water level in the water tank 31 a .

[0084] In some other possible implementations, the water tank 31 a may have more water level detection areas 31 b , and the multiple water level detection areas 31 b are arranged at equal intervals.

[0085] The interval between adjacent water level detection areas 31 b may be the distance between adjacent water level detection areas 31 b along the extending direction of the water tank 31 a .

[0086] In this example, the water tank 31a is annular, and the multiple water level detection areas 31b are arranged at equal intervals, that is, the multiple water level detection areas 31b are arranged at equal angles along the circumference. For example, three, four, or more water level detection areas 31b can be provided, and a water level detection member 50 can be provided for each water level detection area 31b to more accurately determine the amount of water remaining in the water tank 31a.

[0087] In some other possible implementations, in the water level detection area 31 b , a recessed portion 312 a may be provided on the inner plate 311 . Alternatively, the recessed portion 312 a may be provided on both the outer plate 312 and the inner plate 311 .

[0088] Figure 7 This is a schematic diagram of the structure of a water container provided in an embodiment of the present application. Figure 7 As shown, in this example, the inner plate 311 is cylindrical and the cross section of the outer plate 312 is arched, that is, a portion of the outer plate 312 is flat and parallel to the tangent direction of the inner plate 311. The flat portion of the outer plate 312 is located in the water level detection area 31b.

[0089] In this example, the shape change of the overall structure of the outer plate 312 is more gradual, and it is easier to manufacture through a molding process such as injection molding.

[0090] Figure 8 This is a schematic diagram of the structure of a filter provided in an embodiment of the present application. Figure 8 As shown, in this example, the gap 32a of the filter 32 extends from the first end to the second end of the filter 32, that is, the filter 32 is C-shaped. The larger gap 32a can better avoid the water level detection area 31b, preventing the filter 32 from affecting the water level detection.

[0091] Figure 9 This is a schematic diagram of the structure of a filter provided in an embodiment of the present application. Figure 9 As shown, in this example, the filter screen 32 includes two sub-filter screens 321 , which are arranged in sequence along the water tank 31 a , and the water level detection area 31 b is located between adjacent sub-filter screens 321 .

[0092] By configuring the filter screen 32 to be two independent sub-filter screens 321 , a gap exists between adjacent sub-filter screens 321 , thereby avoiding the water level detection area 31 b .

[0093] The number of the sub-filters 321 can be set according to the number of the water level detection areas 31b that need to be avoided. Specifically, the number of the sub-filters 321 can be the same as the number of the water level detection areas 31b that need to be avoided.

[0094] Figure 10 This is a schematic diagram of the structure of a humidifying component provided in an embodiment of the present application. Figure 10 As shown, in this example, the shape of the water tank 31a of the water container 31 is a polygonal frame, specifically a rectangular frame. The water level detection area 31b can be located at a corner of the water tank 31a. The filter 32 includes four sub-filters 321.

[0095] In this example, the water level detection area 31b is positioned at a corner of the water tank 31a to ensure the integrity of the sub-filter 321. There is no need to provide openings or other structures on the sub-filter 321 to avoid the water level detection area 31b. The four sub-filters 321 are independent of each other, making them easy to disassemble and replace individually.

[0096] As an example, the water tank 31a may have four water level detection areas 31b, and one water level detection area 31b may be set at each corner of the water tank 31a. In other examples, water level detection areas 31b may be set only at some corners, for example, 1, 2, or 3 water level detection areas 31b. For another example, when two water level detection areas 31b are set, the two water level detection areas 31b may be set at two diagonally distributed corners.
