For this reason, an object of the utility model is to provide a water tank assembly and an air treatment device, in which the first mounting seat is detachably arranged on the bracket. During the process of adding water to the water tank, after the user removes the bracket, the first mounting seat with the probe can be removed from the bracket, and the bracket can be placed flat on the ground, avoiding damage to the probe and being beneficial to extending the service life of the device.

[0004] A first aspect of the utility model provides a water tank assembly, including: a tank main body, the tank main body includes a water storage cavity, and a water filling port is arranged in the water storage cavity; a bracket, the bracket is detachably arranged at the water filling port; a water level detection assembly, including a first mounting seat and a probe, the first mounting seat is detachably connected with the bracket, the probe is arranged on the first mounting seat, the probe extends along the height direction of the tank main body and enters the water storage cavity.

[0005] In the water tank assembly of the utility model, by detachably connecting the first mounting seat with the probe to the bracket, during the process of adding water to the water tank, when the user removes the first mounting seat, the bracket can be placed flat on the table or the ground, avoiding the situation that the probe protrudes from the bracket during the placement of the bracket due to the integration of the probe and the bracket, resulting in damage to the probe, and being beneficial to extending the service life of the device.

[0006] In some embodiments, one of the first mounting seat and the bracket is provided with a mounting structure, and the other is provided with a matching structure that cooperates with the mounting structure. The mounting structure is configured to be movable relative to the matching structure, and the bracket and the first mounting seat are detachably connected through the mounting structure and the matching structure.

[0007] The detachable connection between the bracket and the first mounting seat is realized by the cooperation of the mounting structure and the matching structure. The detachable connection can be plug connection, threaded connection or snap connection, etc., which is quick and convenient and has a good connection effect.

[0008] According to some embodiments of the present utility model, a connecting portion protruding radially outward along the side wall of the first mounting seat is provided on the side wall of the first mounting seat. The connecting portion extends circumferentially along the first mounting seat, the mounting structure is arranged on the connecting portion, and the matching structure is arranged on the bracket.

[0009] By providing a connecting portion extending circumferentially along the side wall of the first mounting seat, a structural basis is provided for the arrangement of the mounting structure, so as to facilitate the cooperation between the mounting structure and the matching structure on the bracket, enabling a detachable connection between the first mounting seat and the bracket, with a simple structure and convenient processing.

[0010] According to some embodiments of the present utility model, a slot axially penetrating the connecting portion along the first mounting seat is provided on the connecting portion. The slot constitutes the mounting structure; the matching structure includes an insertion piece. The insertion piece is arranged on one side of the bracket facing the box body, and the insertion piece extends towards one side of the box body along the height direction of the box body. The insertion piece is inserted into the slot; a limiting portion is provided at one end of the insertion piece away from the bracket. The limiting portion extends circumferentially along the connecting portion, and the length of the limiting portion along the circumferential direction of the connecting portion is less than the length of the slot along the circumferential direction of the connecting portion. The first mounting seat rotates between a first position and a second position. When the first mounting seat is in the first position, the projection of the limiting portion in the reference plane exceeds the edge of the projection of the slot in the reference plane. When the first mounting seat is in the second position, the projection of the limiting portion in the reference plane is located within the projection of the slot in the reference plane. The reference plane is perpendicular to the axis of the probe.

[0011] The insertion piece and the slot are in plug-in fit to connect the connecting portion and the bracket. Through the limiting cooperation between the limiting portion and the connecting portion when in the first position, the movement of the first mounting seat away from the bracket along the axis of the probe is limited, enabling a fixed connection between the first mounting seat and the bracket, with a simple structure and convenient installation.

[0012] According to some embodiments of the present utility model, a first protrusion is provided on the side of the connecting portion away from the bracket. The first protrusion and the slot are arranged at intervals along the circumferential direction of the first mounting seat. A groove matching the first protrusion is provided on the side of the limiting portion facing the bracket. When the first mounting seat is in the first position, the first protrusion is snapped into the groove. When the first mounting seat is in the second position, the first protrusion disengages from the groove.

[0013] When the first mounting base is mounted on the bracket, the first protrusion is snapped into the groove to limit the rotation of the first mounting base about the probe axis, further improving the reliability of the connection between the first mounting base and the bracket. At the same time, after the first mounting base is mounted on the bracket, the relative positions of the probe with respect to the bracket and the water tank are determined to ensure the accuracy of the water level detected by the probe in the water tank.

[0014] Further, one side surface of the limiting portion facing the box body further includes a guiding inclined surface, and the guiding inclined surface is located on one side of the groove in the circumferential direction. In the direction in which the first protrusion is screwed into the groove, the distance between the guiding inclined surface and the bracket gradually decreases.

[0015] By providing the guiding inclined surface, it is convenient for the limiting portion to be aligned with the slot, making the process of mounting the first mounting base on the bracket more convenient.

[0016] Further, it further includes: a feedthrough component, the feedthrough component is fixedly arranged on the bracket, and the feedthrough component is configured to conduct the probe and the detection circuit when the first mounting base is connected to the bracket.

[0017] When the first mounting base is mounted on the bracket, the probe is conducted with the detection circuit, and the water level of the water tank can be detected without the user adjusting the position of the probe additionally. The structure is simple and the user operation is convenient, which is beneficial to improving the user satisfaction.

[0018] Further, the bracket is provided with an avoidance space, and both the matching structure and the mounting structure are arranged around the avoidance space; the feedthrough component includes a second mounting base and a conductive end, the second mounting base is embedded in the avoidance space, a second mounting hole is opened on one side of the second mounting base facing the box body, and the conductive end slidably penetrates through the second mounting hole, and the conductive end is configured to be in contact conduction with the probe when the first mounting base is mounted on the bracket.

[0019] When the first mounting base is mounted on the bracket, the insert is inserted into the slot, the limiting portion is in the second position and rotates to the first position. After rotating to the first position, the conductive end is in contact conduction with the probe and is conducted with the detection circuit. The structure is simple and the production is convenient.

[0020] Further, the second mounting base and the bracket are integrally formed, or the second mounting base and the bracket are detachably connected.

[0022] Furthermore, one of the bracket and the second mounting seat is provided with a positioning hole, and the other is provided with a fixing hole, and the feedthrough assembly further comprises: a fastener, and the bracket and the second mounting seat are fixedly connected by the fastener passing through the positioning hole and the fixing hole in sequence.

[0023] The second mounting seat and the bracket are fixedly connected by fasteners, and the structure is simple and easy to assemble and disassemble.

[0024] According to some embodiments of the utility model, a side surface of the second mounting seat close to the bracket protrudes toward the box body 10 to form a mounting portion, and the mounting portion defines an installation space. The feed-through assembly also includes: an elastic member, which is arranged in the installation space, and both ends of the elastic member are respectively connected to the conductive end and the second mounting seat.

[0025] An elastic force is applied to the conductive end through the elastic member. When the first mounting seat is installed on the bracket, the probe squeezes the conductive end to slide away from the probe. The elastic member provides a force toward the probe for the conductive end, so that the conductive end and the probe maintain contact, so that the probe and the detection circuit are stably and continuously conductive, thereby improving the reliability of the structure.

[0026] Furthermore, the feed-through assembly further comprises a mounting plate, the conductive end is fixedly disposed on the mounting plate, and one end of the elastic member away from the bracket abuts against an end surface of the mounting plate facing the bracket.

[0027] The mounting plate provides an action surface for the elastic member to exert a force on the conductive end, so that the force exerted by the elastic member on the conductive end is uniform, further improving the reliability of the structure.

[0028] According to some embodiments of the utility model, a blocking plate is provided in the installation space, the blocking plate is arranged opposite to the second installation hole, and one end of the elastic member close to the bracket abuts against the blocking plate.

[0029] By sealing the installation space with the sealing plate, it is convenient to assemble the feed-through component into the second mounting seat, which is beneficial to improving production efficiency.

[0031] By providing the second convex part, after the plugging plate is installed in the installation space, the movement of the plugging plate away from the installation space along the axial direction of the probe is limited, so that the force exerted by the elastic member on the conductive end is stable, thereby ensuring the stable connection between the probe and the conductive end, which is beneficial to the reliability of the structure and enables the probe to continuously detect the water level in the water tank.

[0032] In some embodiments, a first mounting hole is formed in the first mounting seat, and the probe is fixedly mounted in the first mounting hole.

[0057] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0058] Existing air treatment equipment (such as an air humidifier) is equipped with a probe for detecting the water level. The probe is fixedly installed on the tank cover. When adding water to the water storage cavity of the air treatment equipment, the tank cover needs to be disassembled. The probe protrudes from the tank cover, making it inconvenient to place the tank cover. During placement, it may even cause damage to the probe.

[0059] In view of this, the present utility model provides a water tank assembly and an air treatment equipment. The first mounting seat with a probe is detachably arranged on the bracket. During the process of adding water to the water tank, after the user removes the bracket, the first mounting seat with the probe can be removed from the bracket. The bracket can be placed flat on the ground, which is convenient for placement and can also avoid damage to the probe.

[0060] Next, referring to Figures 1 to 10 , a water tank assembly 1 according to the first aspect of the present utility model will be introduced.

[0061] Referring to Figures 1 to 3 , the water tank assembly 1 of this embodiment can be used in an air treatment equipment 2, such as a humidifier, or can also be used in other water-using equipment. The water tank assembly 1 may include: a tank main body 10, a bracket 20, and a water level detection assembly 30.

[0062] The tank main body 10 includes a water storage cavity 11. The water storage cavity 11 can serve as a water storage and supply structure for the air treatment equipment 2 to supply water to other components (such as an atomization assembly) of the air treatment equipment 2. The water storage cavity 11 is provided with a water filling port. When the water volume in the water storage cavity 11 is insufficient, the user adds water to the water storage cavity 11 through the water filling port.

[0063] The bracket 20 is detachably arranged at the water filling port. For example, the bracket 20 is inserted into the water filling port, the bracket 20 is embedded in the water filling port, or the bracket 20 is directly placed on the water filling port. When the user adds water to the water storage cavity 11, the bracket 20 needs to be removed from the water filling port so as to add water to the water storage cavity 11 through the water filling port.

[0064] The water level detection component 30 may include a first mounting base 31 and a probe 32. The probe 32 is disposed on the first mounting base 31 and extends along the height direction of the box body 10. When the air handling device 2 operates normally, the probe 32 enters the water storage cavity 11 to detect the water level in the water storage cavity 11. The first mounting base 31 is detachably connected to the bracket 20. For example, the first mounting base 31 and the bracket 20 are detachably connected by insertion, snap connection or threaded connection. After the bracket 20 is removed from the water filling port, the first mounting base 31 with the probe 32 can be removed from the bracket 20.

[0065] The principle of the water level detection component 30 for detecting the water level in the water storage cavity 11 is as follows: A detection circuit is provided on the air handling device 2. The probe 32 can be set to two. When the first mounting base 31 is mounted on the bracket 20, the tops of the two probes 32 are respectively connected to both ends of the detection circuit. When the water in the water storage cavity 11 submerges the bottom end of the probe 32, the detection circuit is conducted through the two probes 32 and the water. When the water level in the water storage cavity 11 is different, the length of the metal part of the probe 32 connected to the detection circuit is different, and the current and voltage in the detection circuit are different, thereby reflecting the change of the water level in the water storage cavity 11. When the water level in the water storage cavity 11 is lower than the set water level, the probe 32 is separated from the water, causing the detection circuit to be in an open state, indicating that the water level in the water storage cavity 11 is too low and water needs to be replenished. At this time, the air handling device 2 can remind the user to perform the water filling operation.

[0066] For the water tank assembly 1 of the present utility model, by detachably connecting the first mounting base 31 with the probe 32 to the bracket 20, during the process of adding water to the water tank by the user, the first mounting base 31 is removed, and the bracket 20 can be placed flat on the table or the ground, avoiding the situation that the probe 32 protrudes from the bracket 20 when the bracket 20 is placed, resulting in damage to the probe 32 due to the integral setting of the probe 32 and the bracket 20, which is beneficial to extending the service life of the device. At the same time, the detachable connection between the first mounting base 31 and the bracket 20 enables simple and convenient replacement and maintenance operations. When it is necessary to replace or repair the probe 32, only the first mounting base 31 needs to be removed.

[0067] Reference Figure 6 and Figure 7, in some embodiments, a first mounting hole 314 is formed in the first mounting base 31, and the probe 32 is fixedly mounted in the first mounting hole 314. Among them, the mounting method of the probe 32 can be interference fit mounting and fixing with the first mounting hole 314 to ensure the mounting stability of the probe 32 during operation. When the probe 32 needs to be removed, the probe 32 can be simply pulled out from the first mounting hole 314. Additionally, it can also be replaced when the probe 32 is damaged, that is, the damaged probe 32 is removed from the first mounting base 31, and the probe 32 to be replaced is inserted into the first mounting hole 314. The mounting structure of the probe 32 is relatively simple, which is convenient for disassembly and installation operations.

[0068] Reference Figure 7 , Figure 8 and Figure 10 , further, a limiting end 321 is provided at one end of the probe 32 close to the bracket 20. The limiting end 321 protrudes along the circumferential direction of the probe 32, and the limiting end 321 abuts against the end face of the first mounting base 31 close to the bracket 20. After the probe 32 is installed in place, due to the limiting effect of the limiting end 321, the sliding of the probe 32 into the box body 10 under its own gravity is restricted. In the height direction of the box body 10, the relative positions among the probe 32, the first mounting base 31, and the box body 10 are determined, so that the water level detection result of the probe 32 is accurate.

[0069] Reference Figure 2 , in some embodiments, the water tank assembly 1 further includes a feedthrough assembly 40. The feedthrough assembly 40 is fixedly arranged on the bracket 20. When the first mounting base 31 is connected to the bracket 20, the feedthrough assembly 40 conducts the probe 32 with the detection circuit. During the water filling process, it is not necessary to remove the feedthrough assembly 40 from the bracket 20; after adding water into the water storage cavity 11, only by installing the first mounting base 31 back to the predetermined position on the bracket 20, the probe 32 can be connected to the feedthrough assembly 40, and the probe 32 is conducted with the detection circuit under the action of the feedthrough assembly 40. Without the need for the user to adjust the position of the probe 32 additionally, the water level of the water tank can be detected, which is convenient for the user to operate and is beneficial to improving the user's satisfaction.

[0070] Reference Figure 3 and Figure 5, According to some embodiments of the present utility model, the bracket 20 is provided with an avoidance space 22. The feedthrough component 40 may include a second mounting seat 41 and a conductive end 42. The second mounting seat 41 is embedded in the avoidance space 22. A second mounting hole 411 is formed on one side of the second mounting seat 41 facing the box body 10. The conductive end 42 slidably passes through the second mounting hole 411. One end of the conductive end 42 away from the box body 10 is connected to the detection circuit through a connecting wire. During the process of mounting the first mounting seat 31 on the bracket 20, the top end of the probe 32 gradually approaches the conductive end 42. After the first mounting seat 31 is mounted in place (i.e., rotated to the first position described later), the top end of the probe 32 contacts and presses one end of the conductive end 42 facing the probe 32. The conductive end 42 slides in a direction away from the probe 32 and comes into contact and conduction with the probe 32. When the user mounts the first mounting seat 31 on the bracket 20, the probe 32 is synchronously conducted with the detection circuit, which plays a role in detecting the water level in the water storage cavity 11. The user has fewer operation steps, which is beneficial to improving user satisfaction.

[0071] According to some embodiments of the present utility model, the second mounting seat 41 may be detachably connected to the bracket 20, so that after the conductive end 42 is assembled to the second mounting seat 41, the second mounting seat 41 is then mounted on the bracket 20. The assembly is convenient, which is beneficial to improving production efficiency. Of course, in other embodiments of the present utility model, the second mounting seat 41 may also be integrally formed with the bracket 20, which is convenient for processing and beneficial to mass production.

[0072] Reference Figures 2 to 5 , Further, the feedthrough component 40 may include a fastener 43 for connecting the second mounting seat 41 and the bracket 20. The connection between the second mounting seat 41 and the bracket 20 may be: one of the bracket 20 and the second mounting seat 41 is provided with a positioning hole 23, and the other is provided with a fixing hole 412. For example, the bracket 20 is provided with a positioning hole 23, and the second mounting seat 41 is provided with a fixing hole 412 (as shown in Figure 4 and Figure 5 ), or the second mounting seat 41 is provided with a positioning hole 23, and the bracket 20 is provided with a fixing hole 412. The fastener 43 sequentially passes through the fixing hole 412 and the positioning hole 23 to fixedly connect the second mounting seat 41 and the bracket 20. The structure is simple, and the second mounting seat 41 is convenient to disassemble and assemble.

[0073] Optionally, the fastener 43 may be components such as screws, rivets or pins, etc., so that the cost is easy to control.

[0074] Reference Figure 5 , Figure 8 and Figure 10, according to some embodiments of the present utility model, a mounting portion 413 is formed by protruding the surface of one side of the second mounting seat 41 close to the bracket 20 towards the box body 10. The mounting portion 413 defines a mounting space 4131. The feedthrough assembly 40 may further include: an elastic member 44 for providing a force towards the probe 32 to the conductive end 42. The elastic member 44 is disposed in the mounting space 4131, and both ends of the elastic member 44 are respectively connected to the conductive end 42 and the second mounting seat 41.

[0075] When the first mounting seat 31 is mounted on the bracket 20, the probe 32 presses the conductive end 42 to slide in a direction away from the probe 32. The elastic member 44 provides a force towards the probe 32 to the conductive end 42, so that the conductive end 42 remains in contact with the probe 32, thereby enabling the probe 32 to be stably and continuously conducted with the detection circuit, improving the reliability of the structure. At the same time, since the probe 32 indirectly receives the pressure of the elastic member 44, the limiting end 321 of the probe 32 remains in contact with the end surface of the first mounting seat 31 close to the bracket 20, determining the relative position of the probe 32 in the air handling device 2, making the detection result of the probe 32 accurate.

[0076] Optionally, the elastic member 44 may be a compression spring, a rubber sleeve or an elastic plastic sleeve, etc. In this way, it is beneficial to save the equipment cost.

[0077] It can be understood that the limiting end 321 of the probe 32 and one end of the conductive end 42 close to the probe 32 may be set as a circular end or an arc end, which is convenient for relative movement during the disassembly and assembly of the first mounting seat 31, making the disassembly and assembly process of the first mounting seat 31 more convenient.

[0078] Continue to refer to Figure 8 and Figure 10 , further, the feedthrough assembly 40 may further include a mounting plate 45. The conductive end 42 may be fixedly disposed on the mounting plate 45 through an injection molding process. One end of the elastic member 44 away from the bracket 20 abuts against the end surface of the mounting plate 45 facing the bracket 20. The mounting plate 45 provides a surface for the elastic member 44 to apply a force to the conductive end 42, so that the force of the elastic member 44 received by the conductive end 42 is uniform, thereby improving the reliability of the structure.

[0079] Refer to Figure 8 and Figure 10 , according to some embodiments of the present utility model, a blocking plate 46 may be disposed in the mounting space 4131. The blocking plate 46 is disposed opposite to the second mounting hole 411. One end of the elastic member 44 close to the bracket 20 abuts against the blocking plate 46. By blocking the mounting space 4131 with the blocking plate 46, the elastic member 44, the mounting plate 45 and part of the conductive end 42 of the feedthrough assembly 40 are encapsulated in the mounting space 4131, which is beneficial to improve the production efficiency.

[0080] Understandably, both ends of the elastic member 44 apply acting forces to the plugging plate 46 and the mounting plate 45 respectively. During the process of mounting the first mounting seat 31 to the bracket 20, the probe 32 squeezes the conductive end 42 to displace, and the elastic member 44 contracts and deforms accordingly. After removing the first mounting seat 31, the elastic member 44 drives the conductive end 42 to reset together. In order to prevent the elastic member 44 from changing its position and tilting relative to the axis of the probe 32 during the deformation and displacement process in the mounting space 4131, which may lead to a decrease or even failure of the elastic acting force of the elastic member 44 on the mounting plate 45, on the sides of the mounting plate 45 and the plugging plate 46 facing the elastic member 44, guiding sleeves are respectively protrudingly provided. The two guiding sleeves are coaxially arranged, and both ends of the elastic member 44 are respectively sleeved on the two guiding sleeves, so that the axis of the elastic member 44 does not shift during the deformation and reset process, improving the reliability of the structure.

[0081] Reference Figures 8 to 10 , Further, a plurality of inwardly protruding second convex portions 4132 are circumferentially arranged in the mounting space 4131. The second convex portions 4132 have mounting inclined surfaces facing outside the mounting space 4131. In the direction of approaching the axis of the mounting space 4131 along the radial direction, the distance between the mounting inclined surface and the bracket 20 gradually increases. The side of the second convex portion 4132 facing away from the bracket 20 abuts against the end surface of the plugging plate 46 close to the bracket 20.

[0082] Optionally, the number of the second convex portions 4132 can be set to 4, and they are arranged at intervals of 90° along the circumference of the mounting space 4131 to improve the fixing effect on the plugging plate 46. Of course, the number of the second convex portions 4132 can be selected according to design requirements, and the present application does not limit this.

[0083] When assembling the feedthrough component 40, the mounting plate 45 with the conductive end 42 and the elastic member 44 can be successively encapsulated into the mounting space 4131, and then the plugging plate 46 is squeezed towards the elastic member 44 along the mounting inclined surface, so that the plugging plate 46 crosses the second convex portion 4132 and is embedded into the mounting space 4131, which is convenient for assembly. By providing the second convex portion 4132, after the plugging plate 46 is mounted into the mounting space 4131, the movement of the plugging plate 46 away from the mounting space 4131 along the axial direction of the probe 32 is limited, so that the acting force applied by the elastic member 44 to the conductive end 42 is stable, thereby ensuring the stable connection between the probe 32 and the conductive end 42, being beneficial to the reliability of the structure, and enabling the probe 32 to continuously detect the water level in the water tank.

[0084] In some embodiments, one of the first mounting base 31 and the bracket 20 is provided with a mounting structure, and the other is provided with a mating structure 21 that mates with the mounting structure. For example, the first mounting base 31 may be provided with the mounting structure, and the bracket 20 may be provided with the mating structure 21. Of course, it is also possible that the bracket 20 is provided with the mounting structure and the first mounting base 31 is provided with the mating structure 21.

[0085] The mounting structure can move relative to the mating structure 21, so that the bracket 20 and the first mounting base 31 are detachably connected through the mounting structure and the mating structure 21. Among them, the form of the detachable connection can be: the mounting structure can rotate relative to the mating structure 21 to mount the first mounting base 31 onto the bracket 20 or remove it from the bracket 20; it can also be a plug-in fit between the mounting structure and the mating structure 21. The user only needs to insert or pull out the mounting structure to mount the first mounting base 31 onto the bracket 20 or remove it from the bracket 20, which is quick and convenient and has a good connection effect.

[0086] Optionally, both the mating structure 21 and the mounting structure can be arranged around the avoidance space 22 to facilitate the connection between the probe 32 and the feedthrough component 40 arranged in the avoidance space 22.

[0087] Reference Figure 1 、 Figure 2 、 Figure 6 and Figure 7 It can be understood that when the first mounting base 31 is mounted onto the bracket 20, the probe 32 is synchronously conducted with the detection circuit through the feedthrough component 40 on the second mounting base 41. Since the feedthrough component 40 is arranged in the mounting portion 413 that protrudes into the water storage cavity 11 of the second mounting base 41, the first mounting base 31 can also have a housing structure that protrudes into the water storage cavity 11. When the first mounting base 31 is mounted onto the bracket 20, the housing structure covers the mounting portion 413, making the structure beautiful. At the same time, it avoids the contact point between the probe 32 and the conductive end 42 from being directly exposed in the water storage cavity 11, preventing the conductive end 42 from getting wet and causing electric leakage, thus improving the safety of the device.

[0088] Reference Figure 6 Furthermore, the side wall of the housing structure of the first mounting base 31 is provided with a connecting portion 311 that protrudes radially outward along the first mounting base 31. The connecting portion 311 extends along the circumferential direction of the first mounting base 31. The mounting structure is arranged on the connecting portion 311, and the mating structure 21 is arranged on the bracket 20. The connecting portion 311 provides a structural basis for the arrangement of the mounting structure, facilitating the cooperation between the mounting structure and the mating structure 21 on the bracket 20, so that the first mounting base 31 and the bracket 20 can be detachably connected, with a simple structure and convenient processing.

[0089] Reference Figure 4 and Figure 6, Further, a slot 312 is provided on the connecting portion 311. The slot 312 axially penetrates the connecting portion 311 along the first mounting base 31, and the slot 312 constitutes the above-mentioned mounting structure; the mating structure 21 may include a tab 211. The tab 211 is disposed on the side of the bracket 20 facing the box body 10, and the tab 211 is inserted into the slot 312, so that the first mounting base 31 is connected to the bracket 20.

[0090] The tab 211 extends toward the box body 10 along the height direction of the box body 10, and the tab 211 exceeds the thickness of the connecting portion 311 when the height of the box body 10. A limiting portion 212 is provided at one end of the tab 211 away from the bracket 20. The limiting portion 212 extends along the circumferential direction of the connecting portion 311, and the length of the limiting portion 212 along the circumferential direction of the connecting portion 311 is smaller than the length of the slot 312 along the circumferential direction of the connecting portion 311.

[0091] Reference Figure 8 and Figure 10 , during the process of the user disassembling and installing the first mounting base 31, the first mounting base 31 rotates between a first position and a second position. When the first mounting base 31 is in the first position, in a reference plane perpendicular to the axis of the probe 32, the projection of the limiting portion 212 exceeds the edge of the projection of the slot 312. In other words, a part of the structure of the limiting portion 212 abuts against the side surface of the connecting portion 311 away from the bracket 20. At this time, the first mounting base 31 is clamped between the limiting portion 212 and the bracket 20, and the first mounting base 31 and the bracket 20 are relatively fixed. When the first mounting base 31 is in the second position, the projection of the limiting portion 212 in the reference plane is located within the projection of the slot 312 in the reference plane. In other words, the limiting portion 212 does not contact the connecting portion 311, and both the limiting portion 212 and the tab 211 are located within the slot 312. At this time, the first mounting base 31 and the bracket 20 are unlocked, and the user only needs to move the first mounting base 31 along the axis direction of the probe 32 to remove the first mounting base 31.

[0092] The process of installing the first mounting base 31 can be as follows: align the slot 312 with the limiting portion 212, move the first mounting base 31 toward the bracket 20, so that the limiting portion 212 is inserted through the slot 312. At this time, the first mounting base 31 is in the second position, and the probe 32 is not in contact and conduction with the conductive end 42. Rotate the first mounting base 31 relative to the bracket 20 to the first position, and the first mounting base 31 is fixedly installed on the bracket 20, and the probe 32 is in contact and conduction with the conductive end 42. The process of the user disassembling the first mounting base 31 can be as follows: rotate the first mounting base 31 relative to the bracket 20 from the first position to the second position, and then move the first mounting base 31 along the axial direction of the probe 32 to disconnect from the bracket 20, and the disassembly process can be completed. The structure is simple and the installation is convenient.

[0093] Reference Figure 4 and Figure 6, Further, a first protrusion 313 is provided on the side of the connecting portion 311 away from the bracket 20. The first protrusion 313 and the slot 312 are arranged at intervals along the circumferential direction of the first mounting seat 31. A groove 2121 matching the first protrusion 313 is provided on the side of the limiting portion 212 facing the bracket 20.

[0094] When the first mounting seat 31 is in the first position (i.e., the first mounting seat 31 is relatively fixed to the bracket 20), the first protrusion 313 is snapped into the groove 2121 to limit the rotation of the first mounting seat 31 around the axis of the probe 32, avoiding relative rotation between the first mounting seat 31 and the bracket 20 during the use of the air handling device 2, which may cause the disconnection between the probe 32 and the conductive end 42, improving the connection reliability between the probe 32 and the conductive end 42. At the same time, after the first mounting seat 31 is installed on the bracket 20, the relative positions of the probe 32 with respect to the bracket 20 and the water tank are determined to ensure the accuracy of the water level detected by the probe 32 in the water tank.

[0095] When the first mounting seat 31 rotates to the second position, the first protrusion 313 disengages from the groove 2121, facilitating the user to disassemble the first mounting seat 31 from the bracket 20.

[0096] Optionally, the mounting structure and the mating structure 21 can be arranged in multiple groups along the circumferential direction of the avoidance space 22. For example, the mounting structure and the mating structure 21 can be arranged in 4 groups at intervals of 90° along the circumferential direction of the avoidance space 22. When the first mounting seat 31 is connected to the bracket 20, the fixing effect on the first mounting seat 31 is improved, enhancing the structural stability. Of course, the number of the mounting structure and the mating structure 21 in the present application is not limited, and can be selected and designed according to needs during production.

[0097] Reference Figure 4 , Further, the surface of the limiting portion 212 facing the tank body 10 further includes a guiding inclined surface 2122. The guiding inclined surface 2122 is located on one side of the groove 2121 along the circumferential direction. In the direction of the first protrusion 313 being screwed into the groove 2121, the distance between the guiding inclined surface 2122 and the bracket 20 gradually decreases. By providing the guiding inclined surface 2122, it is convenient to align the limiting portion 212 with the slot 312, making the process of installing the first mounting seat 31 on the bracket 20 more convenient.

[0098] The disassembly and assembly principle of the probe 32 of the water tank assembly 1 of the present utility model is as follows:

[0099] When water needs to be added to the water storage cavity 11, the user removes the bracket 20 from the water filling port and rotates the first mounting base 31 so that the first mounting base 31 rotates from the first position to the second position. The first protrusion 313 disengages from the groove 2121, the limiting portion 212 disengages from the connecting portion 311, and the conductive end 42 disengages from the probe 32. At this time, the user can move the first mounting base 31 away from the bracket 20 to remove the first mounting base 31, and place the bracket 20 flat on the ground or on the table. After the water addition is completed, align the slot 312 on the connecting portion 311 of the first mounting base 31 with the limiting portion 212 on the bracket 20, and move the first mounting base 31 towards the bracket 20 so that the limiting portion 212 is inserted through the slot 312. At this time, the first mounting base 31 is in the second position, the probe 32 is not in contact and conduction with the conductive end 42. Rotate the first mounting base 31 relative to the bracket 20 to the first position, and the first convex portion gradually snaps into the groove 2121, and the probe 32 is in contact and conduction with the conductive end 42, completing the installation of the first mounting base 31. Then install the bracket 20 back to the water filling port.

[0100] Reference Figure 1 , in the second aspect of the present invention, an air treatment device 2 is further provided. The air treatment device 2 can be a humidifier. The air treatment device 2 can include the above-mentioned water tank assembly 1.

[0101] In the air treatment device 2 of the present invention, due to the use of the above-mentioned water tank assembly 1, during the process of adding water to the water tank, the bracket 20 can be removed from the box body 10, and the first mounting base 31 with the probe 32 can be removed from the bracket 20, so that the bracket 20 can be placed flat on the table or on the ground, without causing damage to the probe 32. After the water addition is completed, install the first mounting base 31 back on the bracket 20, and then assemble the bracket 20 back onto the box body 10. The water addition operation is convenient.
