[0002] At present, during the long-term operation of humidifier-type air treatment equipment, calcium and magnesium ions in water will form scale at the water inlet of the water pump. As the usage time of the air treatment equipment increases, the amount of scale will also increase, affecting the normal operation and service life of the water pump, and it needs to be cleaned in time. However, the water inlet of the water pump in the related technology is not convenient for cleaning. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the utility model is to provide a water tank assembly and an air treatment equipment, in which the cover plate of the water tank assembly is configured to be movable relative to the fixed frame, so as to open or close the cleaning port, facilitating the cleaning of the water pump of the water tank assembly.

[0004] The first aspect of the utility model discloses a water tank assembly, including:

[0005] A fixed frame, which defines an installation cavity, and one end of the fixed frame in its own height direction has a cleaning port;

[0006] A water pump, which is arranged in the installation cavity;

[0007] A cover plate, which is arranged at the cleaning port, and the cover plate is configured to be movable relative to the fixed frame to open or close the cleaning port.

[0008] For the water tank assembly of the utility model, after long-term operation, scale is formed at the water inlet of the water pump. The user moves the cover plate relative to the fixed frame to open the cleaning port and clean the water inlet of the water pump. After cleaning, the user only needs to move the cover plate to close the cleaning port. The structure is simple, and the cleaning operation of the water inlet of the water pump of the air treatment equipment is convenient, which is beneficial to improving user satisfaction.

[0009] In some embodiments, the cover plate is provided with a pivot fitting portion and a locking fitting portion distributed along its circumferential direction. The pivot fitting portion is pivotally connected to the fixed frame, and the locking fitting portion is detachably fitted with the fixed frame.

[0010] During the process of the user opening or closing the cover plate, the cover plate rotates around the pivot fitting portion, and the cover plate is opened or closed by the separation or connection between the locking fitting portion and the fixed frame. The structure is simple, and the operation of the user opening and closing the cover plate is convenient.

[0011] According to some embodiments of the present utility model, one of the fixing frame and the cover plate is provided with a pivot shaft, and the other is provided with a mating hole that cooperates with the pivot shaft. The pivot shaft passes through the mating hole, and the cover plate is rotatably arranged around the axis of the pivot shaft.

[0012] During the process of the user rotating the cover plate, the pivot shaft is located in the mating hole, and the cover plate rotates around the axis of the pivot shaft. The structure is simple, and it is convenient for the user to rotate the cover plate to open or close the cleaning port.

[0013] According to some embodiments of the present utility model, the pivot shaft is arranged on the fixing frame. The extending direction of the pivot shaft is parallel to the opening direction of the cleaning port. The mating hole is opened at the edge of the cover plate and penetrates through the cover plate along the height direction of the fixing frame. The mating hole constitutes the pivot fitting portion.

[0014] The mating hole that pivotally cooperates with the pivot shaft is opened at the edge of the cover plate. During the process of the user rotating the cover plate, the cover plate rotates around the mating hole opened at the edge of the cover plate. When the user needs to open the cleaning port to clean the water inlet of the water pump, the cross-section of the exposed cleaning port is large, which is convenient for operating to clean the water inlet of the water pump from the cleaning port.

[0015] According to some embodiments of the present utility model, an installation limiting structure is arranged at one end of the pivot shaft away from the fixing frame. The installation limiting structure cooperates with the cover plate to limit the cover plate.

[0016] Through the cooperation between the installation limiting structure and the cover plate, the cover plate is limited, avoiding the cover plate moving along the axis of the pivot shaft during the process of the user rotating the cover plate, resulting in the disconnection between the cover plate and the pivot shaft, which is beneficial to improving the structural stability.

[0017] According to some embodiments of the present utility model, the installation limiting structure includes a limiting platform. The limiting platform is located at one end of the pivot shaft away from the fixing frame. The limiting platform has a first end away from the fixing frame and a second end close to the fixing frame along the axial direction of the pivot shaft. Along the axial direction of the pivot shaft and from the first end to the second end, the outer diameter of the limiting platform gradually increases. The outer diameter of the first end is smaller than the diameter of the mating hole, and the outer diameter of the second end is larger than the diameter of the mating hole. The second end abuts against the surface of the cover plate away from the fixing frame.

[0018] The limiting platform is inserted into the mating hole with the first end facing the limiting hole. The second end of the limiting platform passes through the mating hole, and the outer diameter of the second end is larger than the diameter of the mating hole. When the cover plate rotates around the pivot shaft, the second end of the limiting platform restricts the cover plate from sliding along the axial direction of the pivot shaft, avoiding the cover plate falling off from the pivot shaft. The structure is simple, the operation of installing the limiting platform into the mating hole is simple, and the practicability is strong.

[0019] According to some embodiments of the present utility model, a deformation groove is defined at a first end of the limiting platform.

[0020] By defining a deformation groove on the limiting platform, when the cover plate is installed on the pivot shaft, both the first end and the second end of the limiting platform pass through the mating hole. Since the outer diameter of the second end is greater than the diameter of the mating hole, the second end will inevitably deform along the radial direction of the mating hole. By providing the deformation groove, it is convenient for the second end of the limiting platform to deform along the radial direction of the mating hole and pass through the mating hole, with a simple structure and convenient assembly operation.

[0021] According to some embodiments of the present utility model, the locking and mating portion is provided at an end of the cover plate along its radial direction opposite to the pivot mating portion, and the fixing frame is provided with a locking structure, and the locking structure is detachably mated with the locking and mating portion.

[0022] The locking structure and the locking and mating portion are provided at an end along the radial direction of the cover plate opposite to the pivot mating portion, with a simple structure and good locking effect on the cover plate.

[0023] According to some embodiments of the present utility model, the locking structure is formed as a mounting hole, and the locking and mating portion is formed as a locking hole.

[0024] The water tank further includes: a locking assembly, the locking assembly includes a locking shaft, the locking shaft is movably inserted through the mounting hole along the axial direction of the mounting hole, and the locking shaft is adapted to pass through the mounting hole and insert into the locking hole to be in locking and mating with the locking hole.

[0025] The locking shaft is inserted through the mounting hole and is in locking and mating with the locking hole. When the user needs to open the cleaning port to clean the water inlet of the water pump, the user only needs to move the locking shaft axially out of the locking hole and rotate the cover plate around the axis of the pivot shaft; when fixing the cover plate to the fixing frame to close the cleaning port, the user inserts the locking shaft into the locking hole, with convenient operation. Since the locking shaft and the pivot shaft are respectively located at two ends of the cover plate along the radial direction, the locking effect on the cover plate is good.

[0026] According to some embodiments of the present utility model, a mounting plate is provided on the fixing frame, and the mounting hole is formed in the mounting plate; a limiting ring extending along the circumferential direction of the locking shaft is provided on the outer wall of the locking shaft, the limiting ring is located between the cover plate and the mounting plate, and the diameter of the limiting ring exceeds the inner diameters of the mounting hole and the locking hole.

[0027] When the user moves the locking shaft away from the locking hole to unlock the connection between the cover plate and the fixing frame, the limiting ring and the mounting plate are limited in cooperation, so that the locking shaft will not fall off the mounting hole. When the user moves the locking shaft to insert the locking hole to connect and fix the cover plate to the fixing frame, the limiting ring and the cover plate are limited in cooperation to prevent the locking shaft from falling off the locking hole. The limiting ring prevents the locking shaft from falling off the locking hole or the mounting hole. The structure is simple and practical. It only needs to process the limiting ring on the outer wall of the locking shaft. The processing is convenient and the cost is low.

[0028] According to some embodiments of the present utility model, the locking assembly further includes: an elastic member, two ends of which are respectively in contact with the limiting ring and the mounting plate.

[0029] When the locking shaft is aligned with the locking hole on the cover plate to fix the cover plate, the locking shaft is inserted into the locking hole under the elastic action of the elastic member, which has a good locking and fixing effect on the cover plate.

[0030] According to some embodiments of the present invention, the locking assembly further comprises: a toggle member, which is disposed on a side of the mounting plate away from the cover plate and connected to an end of the locking shaft away from the cover plate.

[0031] The locking shaft is driven to move by the driving member, making the driving operation more convenient.

[0032] According to some embodiments of the utility model, the locking assembly further includes: a fixing member, the locking shaft defines a fixing hole at one end away from the cover plate, the fixing member is passed through the fixing hole, and the toggle member and the locking shaft are connected via the fixing member.

[0033] The toggle member is fixedly connected to the locking shaft by a fixing member, which is beneficial to the connection and fixation of the toggle member and convenient for the user to toggle the toggle member to drive the locking shaft to move and unlock the cover plate.

[0034] According to some embodiments of the present invention, the locking hole includes a first section and a second section axially away from the fixing frame along the locking shaft, and in the direction axially away from the fixing frame along the locking shaft, the inner diameter of the first section gradually decreases to be equal to the inner diameter of the second section, and the inner diameter of the second section exceeds the diameter of the locking shaft.

[0035] When the user rotates the cover to open the cleaning port, the locking shaft is pushed out of the second section of the locking hole and slides along the inner wall of the first section. The distance between the end of the locking shaft toward the cover and the end face of the cover close to the fixing frame gradually decreases, making it more convenient to open the cover. When the user rotates the cover to open the cleaning port, the cover rotates until the locking shaft approaches the locking hole and slides along the inner wall of the first section to the second section. Since the inner wall of the first section is formed into a cone, the end of the locking shaft toward the cover is automatically aligned to the second section along the cone-shaped first section, and the locking effect is good.

[0036] In some embodiments, a water passing port is provided on the cover plate, and the water tank assembly further includes a filter member disposed at the water passing port.

[0037] When the water tank assembly is working, the water pump sucks water from the water passing port and performs a filtering process at the filter member to filter impurities in the water, making the water quality output by the water tank assembly better.

[0038] The second aspect of the present utility model further provides an air treatment device, including:

[0039] A device main body, where the device main body includes a housing;

[0040] The above-mentioned water tank assembly, and the water tank assembly is disposed inside the housing.

[0041] Due to the use of the above-mentioned water tank assembly, after long-term use, when cleaning the water inlet of the water pump of the air treatment device, the user only needs to rotate the cover plate of the water tank assembly relative to the fixing frame, open the cleaning port, and then the water inlet of the water pump can be cleaned. After that, the user can reset the cover plate. It is convenient to clean the water inlet of the water pump, which is beneficial to extending the service life of the device.

[0063] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0064] Some air treatment devices need to humidify the air during use to change the air humidity, such as air humidifiers, etc. Generally, a water pump is provided in the air treatment device.

[0065] During long-term operation, calcium and magnesium ions in the water generally form scale at the water inlet of the water pump. As the usage time of the air treatment device increases, the amount of scale also increases and needs to be cleaned in time. A cover plate is provided at the water inlet of the water pump, and the cover plate is fixedly installed by bolts, which is not convenient to disassemble during the process of cleaning the water pump.

[0066] In view of this, the present utility model proposes a water tank assembly and an air treatment device, configuring the cover plate to be movable relative to the fixing frame. By moving the cover plate relative to the fixing frame, the user can open the cleaning port to clean the water inlet of the water pump. After cleaning, the user only needs to move the cover plate to close the cleaning port. The structure is simple, and the cleaning operation of the water inlet of the water pump of the air treatment device is convenient, which is beneficial to improving user satisfaction.

[0067] The following refers to Figures 1 to 12 Describe the water tank assembly 1 according to the embodiment of the first aspect of the present utility model.

[0068] Refer to Figure 1 、 Figure 3 Figure 4 And Figure 5 The water tank assembly 1 may include: a fixing frame 11, a water pump 12, and a cover plate 13.

[0069] The fixing frame 11 is mainly used for fixedly installing the water pump 12 and the filter element. The fixing frame 11 can be in a cylindrical shape. The fixing frame 11 defines an installation cavity 111. One end of the fixing frame 11 in its own height direction has a cleaning port. For example, the cleaning port can be arranged at the lower end or the upper end of the fixing frame 11, and the installation cavity 111 can extend along the height of the fixing frame 11.

[0070] The water pump 12 is arranged in the installation cavity 111. In order to facilitate the operation of the water pump 12, in this embodiment, the cleaning port can be arranged at the lower end of the fixing frame 11. The water pump 12 is arranged at the cleaning port, and a support seat can be formed in the installation cavity 111. The water pump 12 is fixedly installed on the fixing frame 11 through the support seat.

[0071] The cover plate 13 is arranged at the cleaning port. The cover plate 13 is configured to be movable relative to the fixing frame 11 to open or close the cleaning port. For example, the cover plate 13 can pivot relative to the fixing frame 11 to open or close the cleaning port, or the cover plate 13 can flip relative to the fixing frame 11 to open or close the cleaning port, or the cover plate 13 can move away from or close to the fixing frame 11 to open or close the cleaning port.

[0072] For the water tank assembly 1 of the present utility model, after long-term operation, the user can move the cover plate 13 relative to the fixing frame 11 to open the cleaning port, so as to clean the water inlet of the water pump 12. After the cleaning is completed, the user only needs to move the cover plate 13 to close the cleaning port. The structure is simple, and the cleaning operation of the water inlet of the water pump 12 of the air treatment equipment is convenient, which is beneficial to improving user satisfaction.

[0073] Continue to refer to Figure 1 , in some embodiments, the water tank assembly 1 may further include a filtering member 15. A water passing port 133 is formed on the cover plate 13, and the water passing port 133 can be used for the water inlet of the water pump 12. The filtering member 15 is arranged at the water passing port 133. The filtering member 15 is used to remove impurities in the water to ensure the cleanliness of the water quality. For example, the filtering member 15 can be a filter net, a filter membrane, a filter cotton, etc. The water pump 12 sucks water from the water passing port 133 and performs a filtering process at the filtering member 15 to filter impurities in the water, so that the water quality output by the water tank assembly 1 is better.

[0074] Continue to refer to Figures 3 to 5 , in some embodiments, a pivoting fitting portion and a locking fitting portion may be provided on the cover plate 13, and the pivoting fitting portion and the locking fitting portion may be distributed along the circumferential direction of the cover plate 13. Among them, the pivoting fitting portion is pivotally connected to the fixing frame 11, so that the cover plate 13 rotates relative to the fixing frame 11, and the rotation direction is as Figure 3 shown to open or close the cleaning port.

[0075] The locking fitting portion is detachably fitted with the fixing frame 11. For example, when the user rotates the cover plate 13 to open the cleaning port, the locking fitting portion is separated from the fixing frame 11, and the cover plate 13 is still connected to the fixing frame 11; when the user rotates the cover plate 13 to close the cleaning port, the locking fitting portion can be connected to the fixing frame 11, which improves the structural stability. The structure is simple, and the operation of the user to open and close the cover plate 13 is convenient.

[0076] Refer to Figures 4 to 6 , further, a pivot shaft 112 is provided on one of the fixing frame 11 and the cover plate 13, and a fitting hole 131 that cooperates with the pivot shaft 112 is provided on the other. For example, the pivot shaft 112 is provided on the fixing frame 11, and the fitting hole 131 is provided on the cover plate 13, or the pivot shaft 112 is provided on the cover plate 13, and the fitting hole 131 is provided on the fixing frame 11; the pivot shaft 112 passes through the fitting hole 131, and the cover plate 13 is rotatably arranged around the axis of the pivot shaft 112. During the process of the user rotating the cover plate 13, the pivot shaft 112 is located in the fitting hole 131, and the cover plate 13 rotates around the axis of the pivot shaft 112. The structure is simple, and the operation of the user to rotate the cover plate 13 to open or close the cleaning port is convenient.

[0077] Continue to refer to Figure 5 and Figure 6, Further, the pivot shaft 112 can be arranged on the fixing frame 11, and the pivot shaft 112 extends along a direction parallel to the opening direction of the cleaning port, that is, the rotation plane of the cover plate 13 is parallel to the plane where the edge of the cleaning port is located. The fitting hole 131 is opened at the edge of the cover plate 13 and penetrates through the cover plate 13 along the height direction of the fixing frame 11, and the fitting hole 131 constitutes the above-mentioned pivot fitting portion.

[0078] Since the fitting hole 131 pivotally fitted with the pivot shaft 112 is opened at the edge of the cover plate 13, when the user needs to open the cleaning port to clean the water inlet of the water pump 12, the cover plate 13 rotates around the pivot shaft 112 or the axis of the fitting hole 131, and the cross-section of the exposed cleaning port is large, which is convenient for operating the water inlet of the water pump 12 at the cleaning port.

[0079] Reference Figure 5 , Figure 6 and Figure 9 , According to some embodiments of the present invention, an installation limiting structure 113 is provided at one end of the pivot shaft 112 away from the fixing frame 11, and the installation limiting structure 113 is in limiting cooperation with the cover plate 13 to limit the cover plate 13. The cover plate 13 is configured to rotate relative to the fixing frame 11 around the pivot shaft 112. The installation limiting structure 113 and the cover plate 13 cooperate to limit the cover plate 13, which can be to limit the axial movement of the cover plate 13 relative to the fixing frame 11 along the pivot shaft 112, avoiding the cover plate 13 moving along the axis of the pivot shaft 112 during the process of the user rotating the cover plate 13, resulting in the disconnection between the cover plate 13 and the pivot shaft 112, which is beneficial to improving the structural stability.

[0080] Continue to refer to Figure 9 , Further, the installation structure can include a limiting platform 1131. The limiting platform 1131 is located at one end of the pivot shaft 112 away from the fixing frame 11. Along the direction away from the fixing frame 11 along the axial direction of the pivot shaft 112, the limiting platform 1131 has a first end 1131a and a second end 1131b, and the second end 1131b is close to the fixing frame 11. Along the axial direction of the pivot shaft 112 and from the first end 1131a to the second end 1131b, the outer diameter of the limiting platform 1131 gradually increases. In other words, the limiting platform 1131 can be a conical platform, and the diameter of the conical platform gradually increases from the first end 1131a to the second end 1131b.

[0081] The outer diameter of the first end 1131a is smaller than the diameter of the mating hole 131, and the outer diameter of the second end 1131b is larger than the diameter of the mating hole 131. When assembling between the cover plate 13 and the pivot shaft 112, the limiting platform 1131 is inserted into the mating hole 131 with the first end 1131a facing the limiting hole. The second end 1131b of the limiting platform 1131 passes through the mating hole 131. Since the outer diameter of the second end 1131b is larger than the diameter of the mating hole 131, the second end 1131b abuts against the surface of the cover plate 13 away from the fixing frame 11. Thus, when the cover plate 13 rotates around the pivot shaft 112, the second end 1131b of the limiting platform 1131 restricts the cover plate 13 from sliding axially along the pivot shaft 112, preventing the cover plate 13 from falling off the pivot shaft 112. The structure is simple, the operation of installing the limiting platform 1131 into the mating hole 131 is simple, and the practicability is strong.

[0082] It can be understood that since the outer diameter of the second end 1131b is larger than the diameter of the mating hole 131, during assembly, the second end 1131b will deform radially inward along the mating hole 131 to facilitate passing through the mating hole 131. Therefore, the limiting platform 1131 can be elastic. For example, the limiting platform 1131 can be made of an elastic material such as rubber or plastic. Or, the limiting platform 1131 can also have a structure that facilitates deformation. For example, a cavity is defined at the first end 1131a of the limiting platform 1131, and the cavity extends all the way to the second end 1131b of the limiting platform 1131 or into the pivot shaft 112. During the assembly process of the cover plate 13 and the pivot shaft 112, when the second end 1131b passes through the mating hole 131, it is subjected to the extrusion of the mating hole 131, and the edge of the second end 1131b deforms by displacing into the cavity, so as to pass through the mating hole 131, and then the edge of the second end 1131b resets and abuts against the surface of the cover plate 13 away from the fixing frame 11 to limit the axial movement of the cover plate 13 along the pivot shaft 112. On the other hand, machining a cavity in the limiting platform 1131 can reduce the material used, thus saving costs.

[0083] Continue to refer to Figure 6 Furthermore, a deformation groove 1132 is defined at the first end 1131a of the limiting platform 1131. The deformation groove 1132 extends towards the second end 1131b, and the deformation groove 1132 penetrates the outer wall of the limiting platform 1131 in a direction perpendicular to the axis of the pivot shaft 112. In this way, the limiting platform 1131 forms two relatively arranged elastic pieces, enabling the second end 1131b to pass through the mating hole 131 more conveniently.

[0084] Understandably, the bottom wall and the side wall of the deformation groove 1132 can be transitioned through an arc surface, so as to avoid stress concentration at the connection between the bottom wall and the side wall of the deformation groove 1132 when the second end 1131b is deformed by the extrusion force during assembly through the mating hole 131, which may cause damage to the limiting platform 1131, and is beneficial to improving the structural stability.

[0085] In some embodiments, the locking and mating portion is provided at one end of the cover plate 13 along its radial direction and opposite to the pivoting and mating portion. In other words, in the radial direction of the cover plate 13, the locking and mating portion and the pivoting and mating portion are symmetrically arranged about the axis of the cover plate 13. Compared with the locking and mating portion and the pivoting and mating portion being arranged at other positions, when the locking and mating portion and the pivoting and mating portion are arranged at the relative positions in this embodiment, the locking effect is the best.

[0086] Reference Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 10 、 Figure 11 and Figure 12 , the fixing frame 11 is provided with a locking structure, and the locking structure is detachably engaged with the locking and mating portion. For example, when the user needs to open the cleaning port, the locking structure is separated from the locking and mating portion; when the user needs to close the cleaning port, the locking structure is connected to the locking and mating portion, thereby completing the locking of the cover plate 13.

[0087] Furthermore, the locking structure can be formed as the mounting hole 114, and the locking and mating portion can be formed as the locking hole 132. The water tank further includes: a locking component 14, and the locking structure and the locking and mating portion can be detachably engaged through the locking component 14.

[0088] The locking component 14 can include a locking shaft 141. The locking shaft 141 is movably inserted through the mounting hole 114 along the axial direction of the mounting hole 114. The locking shaft 141 is adapted to pass through the mounting hole 114 and insert into the locking hole 132 to be locked and mated with the locking hole 132. Here, the locking and mating between the locking shaft 141 and the locking hole 132 can be: when the user needs to open the cleaning port to clean the water inlet of the water pump 12, the user only needs to move the locking shaft 141 axially out of the locking hole 132 and rotate the cover plate 13 around the axis of the pivot shaft 112; when fixing the cover plate 13 to the fixing frame 11 to close the cleaning port, the user inserts the locking shaft 141 into the locking hole 132, which is convenient to operate. Moreover, the locking shaft 141 and the pivot shaft 112 are respectively located at both ends of the cover plate 13 along the radial direction, and the locking effect on the cover plate 13 is good.

[0089] Continue to refer to Figure 3 and Figure 5According to some embodiments of the present utility model, a mounting plate 115 is provided on the fixing frame 11, and a mounting hole 114 is formed on the mounting plate 115; the outer wall of the locking shaft 141 is provided with a limiting ring 1411 extending along its own circumference, and the limiting ring 1411 is located between the cover plate 13 and the mounting plate 115, and the diameter of the limiting ring 1411 exceeds the inner diameter of the mounting hole 114 and the locking hole 132.

[0090] When the user moves the locking shaft 141, the locking shaft 141 will not be separated from the mounting hole 114 or the locking hole 132 under the limiting effect of the limiting ring 1411. For example, when the user moves the locking shaft 141 away from the locking hole 132 to unlock the connection between the cover plate 13 and the fixing frame 11, the limiting ring 1411 and the mounting plate 115 are limited and cooperated, so that the locking shaft 141 will not be separated from the mounting hole 114. When 141 is inserted into the locking hole 132 to connect and fix the cover 13 to the fixing frame 11, the limiting ring 1411 and the cover 13 are limited and cooperated to prevent the locking shaft 141 from escaping from the locking hole 132. The limiting ring 1411 prevents the locking shaft 141 from escaping from the locking hole 132 or the mounting hole 114. The structure is simple and practical. It only needs to process the limiting ring 1411 on the outer wall of the locking shaft 141. The processing is convenient and the cost is low.

[0091] Continue to refer Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 10 , Figure 11 and Figure 12 According to some embodiments of the present invention, the locking assembly 14 further includes an elastic member 142 , and two ends of the elastic member 142 are respectively in contact with the limiting ring 1411 and the mounting plate 115 .

[0092] The elastic member 142 is used to provide a force for the locking shaft 141 to move away from the fixing frame 11 along the axial direction of the locking shaft 141. In this embodiment, the elastic member 142 can be a compression spring, and the two ends of the compression spring are respectively in contact with the limit ring 1411 and the mounting plate 115; or the elastic member 142 can also be a rubber sleeve, and the two ends of the rubber sleeve are respectively in contact with the limit ring 1411 and the mounting plate 115. When the locking shaft 141 is aligned with the locking hole 132 on the cover plate 13 to fix the cover plate 13, the locking shaft 141 is inserted into the locking hole 132 under the elastic action of the elastic member 142, and the locking and fixing effect of the cover plate 13 is good. Moreover, after the user stops applying force to the locking shaft 141, the elastic member 142 can drive the locking shaft 141 to automatically reset.

[0093] refer to Figure 2 , Figure 7 , Figure 8 , Figure 10 , Figure 11and Figure 12 According to some embodiments of the present invention, the locking assembly 14 further includes: a toggle member 143, which is disposed on a side of the mounting plate 115 away from the cover plate 13 and connected to an end of the locking shaft 141 away from the cover plate 13. The toggle member 143 is provided to facilitate the user to toggle the locking shaft 141, and saves effort in toggling the locking shaft 141. For example, the toggle member 143 may be a paddle, which extends away from the fixing frame 11 along the radial direction of the locking shaft 141. The position of the locking shaft 141 may be changed by toggling the paddle, which has a simple structure and convenient toggling operation; or the toggle member 143 may be a groove provided on the peripheral side of the locking shaft 141, which facilitates the user to apply force to the locking shaft 141 to adjust the position of the locking shaft 141.

[0094] Furthermore, when the toggle member 143 is a paddle, the locking assembly 14 may further include: a fixing member 144, a fixing hole 1412 is defined at one end of the locking shaft 141 away from the cover plate 13, the fixing member 144 is passed through the fixing hole 1412, and the toggle member 143 and the locking shaft 141 are connected via the fixing member 144. The fixing member 144 is used to fix the toggle member 143 and the locking shaft 141, so that the user can toggle the toggle member 143 to drive the locking shaft 141 to move and unlock the cover plate 13. The fixing member 144 may be a screw, a bolt, a stud or other parts.

[0095] refer to Figure 8 , Figure 10 , Figure 11 and Figure 12 According to some embodiments of the present invention, the locking hole 132 includes a first section 132a and a second section 132b that are axially away from the fixing frame 11 along the locking shaft 141, and the inner diameter of the first section 132a gradually decreases to be equal to the inner diameter of the second section 132b in the direction of axially away from the fixing frame 11 along the locking shaft 141, and the inner diameter of the second section 132b exceeds the diameter of the locking shaft 141. In other words, the first section 132a of the locking hole 132 is a tapered hole, and the axial diameter of the first section 132a gradually decreases to be equal to the second section 132b in the direction of axially away from the fixing frame 11 along the locking shaft 141.

[0096] When the user rotates the cover 13 to open the cleaning port, the locking shaft 141 is pushed out of the second section 132b of the locking hole 132 and slides along the inner wall of the first section 132a. The distance between the locking shaft 141 toward one end of the cover 13 and the end face of the cover 13 close to the fixing frame 11 gradually decreases, making it more convenient to open the cover 13. When the user rotates the cover 13 to open the cleaning port, the cover 13 rotates until the locking shaft 141 is close to the locking hole 132 and slides along the inner wall of the first section 132a to the second section 132b. Since the inner wall of the first section 132a is formed into a cone, the locking shaft 141 automatically aligns to the second section 132b during the sliding process along the tapered first section 132a toward one end of the cover 13, and the locking effect is good.

[0097] It can be understood that in order to facilitate the locking cooperation between the locking shaft 141 and the locking hole 132, the locking shaft 141 has a circular end on the end away from the fixing frame 11, which is beneficial to reduce the friction between the locking shaft 141 and the locking hole 132 and extend the service life of the water tank assembly 1.

[0098] The cleaning process of the water inlet of the water pump 12 of the water tank assembly 1 of the utility model is as follows:

[0099] After long-term use, the user applies an axial force to the toggle member 143 along the locking shaft 141, driving the locking shaft 141 to gradually disengage from the second section 132b and the first section 132a of the locking hole 132, unlocking the cover 13. Then the user applies a force to the cover 13, and the cover 13 rotates around the pivot shaft 112 to open the cleaning port, and cleans the scale at the water inlet of the water pump 12 from the cleaning port.

[0100] The second aspect of the present invention also provides an air treatment device, which may be a humidifier. The air treatment device may include: a device body and the water tank assembly 1, wherein the device body includes a housing; and the water tank assembly 1 is disposed in the housing.

[0101] In this embodiment, the air treatment equipment can be an air humidifier, and the air treatment equipment can also include an atomization component and an air supply component. The water pump 12 of the water tank component 1 supplies water to the atomization component, and the atomization component atomizes the water and blows it out through the air supply component to improve the ambient humidity.

[0102] The working principle of the water tank assembly 1 in the air handling equipment is:

[0103] The fixing frame 11 is installed in the shell. In the shell, water is added to the outside of the fixing frame 11. The water pump 12 draws water through the water inlet 133 on the cover plate 13 and sends water to the atomizing component. The atomizing component atomizes the water and blows it out through the air supply component to improve the environmental humidity.

[0104] For the air handling device of this embodiment, since the above-mentioned water tank assembly 1 is used, after long-term use, the user only needs to rotate the cover plate 13 of the water tank assembly 1 relative to the fixed frame 11 to open the cleaning port, and then the water inlet of the water pump 12 can be cleaned. After that, the user can reset the cover plate 13. It is convenient to clean the water inlet of the water pump 12, which is beneficial to extending the service life of the device.
