Detailed Implementation

[0028] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0029] Firstly, embodiments of this application provide a water tank assembly that can be applied to devices such as humidifiers or air purifiers with humidification functions. For example... Figure 1 As shown, the water tank assembly mainly includes a water tank 10 and a water pump assembly 20.

[0030] Specifically, such as Figure 2 As shown, the inner bottom surface of the water tank 10 is recessed to form a receiving groove 11, which can be integrally formed with the inner bottom surface of the water tank 10. Figure 5 , Figure 6 As shown, the water pump assembly 20 includes a wireless water pump 21, a water pump cover 22, and a transmitter module 23. The water pump cover 22 is detachably installed inside the water tank 10, and its periphery mates with the opening edge of the receiving groove 11 to form a receiving cavity 24. A gap can be left between one side of the water pump cover 22 and the opening edge of the receiving groove 11 to allow water to flow into the receiving cavity 24. The wireless water pump 21 is detachably installed inside the receiving cavity 24. A receiver module 211 is located at the bottom of the wireless water pump 21, and the transmitter module 23 is fixed to the outer bottom of the receiving groove 11, directly opposite the receiver module 211, to achieve wireless power supply. This internal and external isolation structure fundamentally achieves water and electricity separation, ensuring safety during use.

[0031] In some embodiments, a filter cotton (not shown) is provided at the water inlet of the wireless water pump 21 to filter impurities in the water in the accommodating cavity 24 and prevent impurities from entering the wireless water pump 21 and causing blockage or wear.

[0032] In some embodiments, such as Figure 6 , Figure 8As shown, the wireless water pump 21 is detachably fixed on the water pump cover 22, and the top surface of the water pump cover 22 is provided with an operation part 221 for facilitating the force application to detach the water pump cover 22 from the water tank 10. The operation part 221 can be, for example, a knob, a wing-shaped handle, a groove for facilitating the finger pinch, or an asymmetric protrusion, so as to facilitate the user to hold by one hand and apply a torsional force, thereby conveniently detaching or installing the water pump cover 22 together with the wireless water pump 21 fixed thereon as a whole from the water tank 10, effectively simplifying the cleaning and maintenance process.

[0033] In some embodiments, as shown in Figure 7 , Figure 8 As shown, the outer surface of the wireless water pump 21 is sleeved with a damping sleeve 212, for example, a silica gel sleeve, to alleviate the vibration generated when the wireless water pump 21 is working and reduce the noise. The bottom surface of the water pump cover 22, i.e., the surface facing the accommodating cavity 24, is provided with connecting ears 222, and the connecting ears 222 are provided with clamping holes 223. The damping sleeve 212 is provided with buckles 213 corresponding to the positions of the clamping holes 223. In specific implementation, two connecting ears 222 are oppositely arranged, and two buckles 213 are correspondingly arranged. The damping sleeve 212 is fixed on the water pump cover 22 by the buckles 213 and the clamping holes 223 of the connecting ears 222, and the connection is stable.

[0034] In some embodiments, a locking structure is arranged between the water pump cover 22 and the water tank 10, and the water pump cover 22 is switched between the locked state and the unlocked state through the locking structure. When the water pump cover 22 is in the locked state, the locking structure limits the water pump cover 22 in the axial and circumferential directions, ensuring that it is fixed relative to the water tank 10. When the water pump cover 22 is in the unlocked state, the water pump cover 22 can rotate horizontally relative to the water tank 10, so that the mechanical engagement between the two is disengaged, so that the water pump cover 22 can be detached from the water tank 10. In specific implementation, internal threads can be arranged on the inner wall of the accommodating groove 11, and external threads that cooperate with the internal threads can be arranged on the periphery of the water pump cover 22. By rotating the water pump cover 22, the switching between the locked state and the unlocked state of the water pump cover 22 is realized through the engagement of the threads. Of course, in other embodiments, a resilient clamping tongue or clamping claw can be arranged on the water pump cover 22 or the wall of the accommodating groove 11, and a clamping groove is arranged on the corresponding part. By pressing, the clamping tongue / clamping claw is elastically deformed and passes over the obstacle to enter the clamping groove, thereby achieving locking. When disassembling, the clamping tongue / clamping claw usually needs to be pressed to disengage.

[0035] In a specific embodiment, as shown in Figure 5 , Figure 7 The locking structure includes a plurality of clamping blocks 31 arranged in a ring shape and spaced apart on the groove wall of the accommodating groove 11, and a plurality of buckling blocks 32 arranged in a ring shape and spaced apart on the periphery of the bottom of the water pump cover 22. One side of the buckling block 32 is formed with a sliding groove 321 that slidably cooperates with the clamping block 31. Each clamping block 31 and each buckling block 32 are correspondingly arranged, ensuring correct alignment and uniform distribution of force during installation.

[0036] Meanwhile, as shown in Figure 7 , Figure 8 , Figure 9 , the slot wall of the accommodating groove 11 is provided with an arc-shaped protrusion 33 corresponding to the position of the clamping block 31, and the side wall of at least one of the buckling blocks 32 is provided with a first arc-shaped protrusion 322 and a second arc-shaped protrusion 323, and a locking groove 324 is formed between the first arc-shaped protrusion 322 and the second arc-shaped protrusion 323. When the arc-shaped protrusion 33 slides through the first arc-shaped protrusion 322 and enters the locking groove 324, it is elastically locked with the corresponding buckling block 32, and the water pump cover 22 is in a locked state, and the second arc-shaped protrusion 323 is used to prevent the arc-shaped protrusion 33 from continuing to slide. In this embodiment, the material of the water pump cover 22 or the water tank 10 can be plastic, which has a certain elasticity.

[0037] Specifically, referring to Figures 7 to 10 , when the water pump cover 22 is placed at the entrance of the accommodating groove 11 and rotated, the clamping block 31 first freely slides in the sliding groove 321, and as the rotation continues, the fixed arc-shaped protrusion 33 will contact the moving first arc-shaped protrusion 322. Only a slight torque needs to be applied to make the arc-shaped protrusion 33 forcibly pass over the top of the first arc-shaped protrusion 322 and fall into the locking groove 324 behind it. At this time, the arc-shaped protrusion 33 is clamped in the locking groove 324 by the first arc-shaped protrusion 322 and the second arc-shaped protrusion 323, and an elastic locking force is generated between them, effectively preventing the water pump cover 22 from being loosened by reverse rotation due to vibration or accidental touch, so that the water pump cover 22 is stably locked. In addition, the second arc-shaped protrusion 323 also plays a role in limiting the rotation end point, preventing the arc-shaped protrusion 33 from continuing to slide, and ensuring that each locking can stop at the predetermined position. This design not only connects reliably, but also provides clear tactile feedback to the user, improving the operation experience.

[0038] As shown in Figure 5 , Figure 9 , Figure 10 , the clamping block provided with the first arc-shaped protrusion 322 and the second arc-shaped protrusion 323 is provided with a second through hole 325 near the top end, and the width of the second through hole 325 is slightly smaller than the overall width of the clamping block 31. By providing the second through hole 325, the buckling block 32 has greater deformation ability, which is beneficial to the elastic locking state of the arc-shaped protrusion 33 sliding into the locking groove 324.

[0039] In some embodiments, as shown in Figure 1 , Figure 3 , Figure 6As shown, the water pump cover 22 is provided with a water inlet hole 224 which is in communication with the accommodating cavity 24, so that the water in the water tank 10 can enter the accommodating cavity 24 from the water inlet hole 224 for extraction by the wireless water pump 21. The wireless water pump 21 is provided with a water outlet pipe 214, and the water pump cover 22 is provided with a first through hole 225 through which the water outlet pipe 214 or an upper water pipe of a wet curtain assembly (not shown in the figure) of a humidifier passes, so as to form a complete water path.

[0040] As shown in the figures, Figure 9 the water pump cover 22 comprises a circular cover plate 22a and a hollow protrusion 2210 which protrudes upward from the cover plate 22a. The cover plate 22a can have a structure which is low in the middle and high around, i.e. the cover plate 22a is concave downward, guiding the water flow to converge at a low place. Figure 6 、 Figure 8 As shown, a part of the water inlet hole 224 can extend to the cover plate 22a, which is beneficial for the water in the water tank to flow rapidly from the water inlet hole 224 into the accommodating cavity 24.

[0041] In some embodiments, as shown in the figures, Figure 1 、 Figure 4 the operation part 221 is a hollow protrusion 2210 which protrudes from the top surface of the water pump cover 22 and is suitable for hand screwing. In particular implementation, as shown in the figures, Figure 3 、 Figure 9 the protrusion 2210 has opposite first and second ends 2211 and 2212, the first end 2211 of which is close to the inner side wall of the water tank 10, and the width of the protrusion 2210 gradually increases from the first end 2211 to the second end 2212, so that the protrusion 2210 can better apply torque when being screwed. The top of the protrusion 2210 can also be provided with a force application mark such as a screwing direction indicating arrow, so as to provide clear operation guidance.

[0042] In addition, the first through hole 225 is provided in the top wall of the protrusion 2210, and the water outlet pipe 214 is arranged on the top surface of the wireless water pump 21 and extends into the protrusion 2210, so that the overall structural layout is more compact and the space occupation is reduced. At the same time, the water inlet hole 224 can also be provided in the side wall of the protrusion 2210.

[0043] In some embodiments, as shown in the figures, Figure 2 、 Figure 6As shown, one side of the accommodating groove 11 is formed with a flat position 111, and the water tank 10 is provided with a fixed groove 12 corresponding to the position of the flat position 111, and the fixed groove 12 is provided with a water level detection plate 13, so that more space can be saved below the water tank 10, and the structure between each assembly component below the water tank 10 is more compact. The fixed groove 12 is provided with a float groove 14 corresponding to the position of the fixed groove 12 in the accommodating groove 11, and the float groove 14 is provided with a float 15 used in cooperation with the water level detection plate 13. With this structure design, the fixed groove 12 forms a water and electricity separated installation area, and the water level detection plate 13 is safely placed in it. Correspondingly, in the inside of the accommodating cavity 24, that is, in the water tank 10, a float groove 14 for guiding and limiting is provided, and a float 15 is contained in the float groove 14 to move up and down with the rise and fall of the water level. The float 15 cooperates with the water level detection plate 13 across the wall of the water tank 10 to realize non-contact monitoring of the water level.

[0044] As shown in Figure 10 , Figure 11 As shown, the float groove 14 is provided with a water inlet groove 141 away from one side of the water level detection plate 13, and the side wall of the float 15 is provided with a convex 151 extending into the water inlet groove 141, and the upper end of the water inlet groove 141 is provided with a connecting section 144 across the water inlet groove 141, and the inner side wall of the connecting section 144 is provided with a guide slope 142, and the thickness of the connecting section 144 corresponding to the area of the guide slope gradually increases from top to bottom. The setting of the guide slope 142 makes the connecting section 144 at the upper end of the water inlet groove 141 easy to deform, and the area of the connecting section 144 corresponding to the guide slope can form an elastic part 143 with varying thickness, and when the float 15 is installed, the force is pressed into the float groove 14, and the convex 151 on one side of the float 15 abuts against the elastic part 143, and the elastic part 143 deforms, and the float 15 can be more easily installed into the float groove 14. Compared with the existing structure of setting a reverse buckle at the upper end of the float groove, this structure improves the installation efficiency of the float, and the float cannot be pulled out of the float groove after being installed in the float groove. The setting of the guide slope 142 forms a structure that is easy to install the float 15 and can prevent the float 15 from being pulled out of the float groove 14 and causing the loss of the float 15, which is simple in structure and discards the complex structure of the existing limiting pin for preventing the float from being pulled out, thereby reducing the components and installation procedures.

[0045] In specific implementation, as shown in Figure 11As shown, the convex bump 151 is roughly in a truncated cone structure, and the diameter of the small-diameter end of the convex bump 151 is smaller than the width of the water inlet groove 141. When the float 15 is pressed into the float groove 14, the small-diameter end of the convex bump 151 will first contact the guide slope 142, and due to the smooth contact between the guide slope 142 and the convex bump 151, the elastic part 143 will be stably and controllably pushed outward, causing elastic deformation. As the float continues to be pushed in, the convex bump 151 will completely pass over the elastic part 143 and enter the water inlet groove 141. If an attempt is made to install it in reverse, the side of the float 15 without the convex bump 151 will not be able to cooperate with the guide slope 142, and the connecting section at the top end of the water inlet groove 141 will not be able to elastically deform, so the float 15 cannot be installed into the float groove 14, thereby preventing the float 15 from being installed in reverse.

[0046] In the present embodiment, the wireless water pump 21 can be a water pump with integrated water level detection function, which is used in combination with the float 15 and the water level detection plate 13 to improve the accuracy of water level detection.

[0047] As shown in Figure 5 , Figure 10 One side of the wireless water pump 21 is provided with a water level detection probe 21a. When the water level drops to a preset position, the water level detection probe 21a sends a control signal to the wireless water pump 21 to control the wireless water pump 21 to stop pumping water. This can avoid the situation where the wireless water pump 21 emits a "beep" noise due to the small amount of water in the accommodation groove 11, thereby reducing the operating noise of the equipment.

[0048] In some embodiments, as shown in Figure 2 , Figure 6 The transmitting module 23 is prone to damage due to extrusion or impact. Therefore, a protective cover 16 can be connected to the outer bottom of the accommodation groove 11, and the transmitting module 23 is arranged in the protective cover 16. One side of the protective cover 16 is provided with a wire outlet 161. In specific implementation, the protective cover 16 is connected to the outer bottom of the accommodation groove 11 by buckling or screwing, and cooperates with the outer bottom of the accommodation groove 11 to form a closed storage space, thereby preventing the transmitting module 23 from being affected by dust, splashing water or physical impact.

[0049] In a second aspect, the present application provides a humidifier comprising the water tank assembly of any one of the embodiments of the first aspect. In specific implementation, the water tank assembly is detachably mounted on the main body of the humidifier. Since the humidifier adopts the aforementioned water tank assembly, the risk of electric leakage caused by the water pump power line entering the water is fundamentally eliminated, the safety of use is ensured, and the daily cleaning and maintenance of the water pump by the user are also made simple and convenient.

[0050] In some embodiments, the electric control box of the humidifier is buckled to the bottom surface of the water tank 10. After the water level detection plate 13 is inserted into the fixing groove 12, the protrusion on one side of the electric control box abuts against the bottom surface of the water level detection plate 13, thereby preventing the water level detection plate 13 from falling off.

[0051] The water tank assembly and humidifier designed in the application realize complete physical isolation of the energy emitting end and the water using end by arranging the water pump assembly containing the wireless water pump inside the groove and arranging the emitting module outside the groove, fundamentally eliminate the risk of electric leakage, and ensure the use safety. The wireless water pump is connected with the detachable water pump cover, so that the user can take out the wireless water pump when detaching the water pump cover, effectively simplifying the cleaning and maintenance operation, and improving the convenience of use.
