[0040] The present invention provides a dehumidifier.

[0041] In the embodiments of the present invention, please refer to Figures 1 to 3 The dehumidifier includes a water tank 20, a body 10, and a drain pump. The body 10 is in an operating state. In the operating state, the body 10 is located above the water tank 20, and the housing 11 of the body 10 is provided with a drain position. The drain pump is provided in the body 10, and the water outlet of the drain pump is connected to the drain position. The water inlet of the drain pump is connected to the water tank 20, and the water inlet of the drain pump is provided with a filter. It should be noted that the water inlet of the drain pump is the end from which water enters the drain pump during operation, while the water outlet of the drain pump is the end from which water is discharged during operation.

[0042] In the technical solution of the present invention, the water tank 20 is externally positioned below the main body 10 during operation. Compared to a solution in which the water tank 20 is internally positioned within the main body 10, this solution allows the water tank 20 to have a larger capacity, thereby accommodating more dehumidified water. The water in the water tank 20 can also be drained via a drain pump, allowing it to be drained without having to carry the water tank 20 or remove the main body 10. This reduces the need for users to carry the water tank 20 to empty the water. Furthermore, a filter 50 is provided at the water inlet of the drain pump to filter impurities such as dust particles from the water in the water tank 20, reducing the possibility of impurities entering the drain pump and causing blockage.

[0043] To facilitate filter replacement, in one embodiment, the filter 50 is disposed outside the housing 11. That is, the filter 50 may or may not be disposed on the housing 11. Compared to disposing the filter 50 inside the housing 11, this arrangement makes it easier for the user to replace the filter 50. Of course, in other embodiments, the filter 50 may also be disposed inside the housing 11.

[0044] In one embodiment, a suction pipe 30 is provided at the water inlet end of the drain pump. The suction pipe 30 extends into the water tank 20, and a filter 50 is provided at the end of the suction pipe 30 that extends into the water tank 20. Specifically, the drain pump has a water inlet at the water inlet end. When the suction pipe 30 is provided at the water inlet end of the drain pump, one end of the suction pipe 30 is connected to the water inlet of the drain pump, and the other end extends into the water tank 20. When the suction pipe 30 is provided, the suction pipe can be extended to the bottom of the water tank 20, thereby allowing the maximum amount of water in the water tank 20 to be extracted. By providing the filter 50 at the end of the suction pipe 30 that extends into the water tank 20, replacement of the filter 50 is facilitated. The suction pipe 30 can be connected to the water inlet of the drain pump, or the suction pipe 30 can be connected to the water inlet of the drain pump via an inlet pipe.

[0045] To facilitate replacement of the filter element 50 or the water suction pipe 30, in one embodiment, the filter element 50 is detachably connected to the water suction pipe 30. Alternatively, in other embodiments, the filter element 50 may be positioned between the drain pump and the water suction pipe 30, or at the water inlet of the drain pump.

[0046] After the filter element 50 has been used for a long time, impurities accumulate in the filter element 50, affecting the water flow into the water pump 30 and requiring replacement of the filter element 50. To reduce the cost of replacing the filter element 50, in one embodiment, the filter element 50 includes an upper cover 51, a lower cover 52, and a filter screen. The upper cover 51 has a water outlet 512 connected to the water pump 30, and the lower cover 52 has a water inlet 521. The filter screen is positioned between the water outlet 512 and the water inlet 521. The upper and lower covers 51, 52 are detachably connected. Thus, when impurities accumulate in the filter element 50, the user can remove the upper and lower covers 51, 52 to replace the filter screen. This allows the upper and lower covers 51, 52 to be reused, reducing resource waste and eliminating the need to replace the entire filter element 50, thereby reducing user costs. The upper and lower covers 51, 52 can be connected by screws, threaded, or snap-fitted. The filter element 50 may be substantially cylindrical, prismatic, or in other shapes.

[0047] In one embodiment, the upper cover 51 and lower cover 52 are made of plastic to facilitate molding and reduce costs. Of course, in other embodiments, the upper cover 51 and lower cover 52 can also be made of metal or other materials. To facilitate the connection of the water extraction pipe 30 to the filter element 50, in one embodiment, the upper cover 51 is provided with a water outlet connector 511 having a water outlet 512 formed therein. The water extraction pipe 30 is sleeved onto the water outlet connector 511.

[0048] When the filter element 50 is positioned at the lower end of the water extraction pipe 30, to prevent the filter element 50 from contacting the inner wall of the water tank 20 and thereby blocking the water inlet 521, in one embodiment, the water inlet 521 includes a bottom water inlet hole 523 located at the bottom of the lower cover 52 and a side water inlet hole 522 located on the side of the lower cover 52. The filter screen is positioned between the water outlet and the side water inlet hole 522. This means that when the drain pump is pumping water, dehumidified water can enter the filter screen through both the bottom water inlet hole 523 and the side water inlet hole 522. Even if the bottom water inlet hole 523 is blocked by the lower cover 52 abutting the inner wall of the water tank 20, dehumidified water can still enter through the side water inlet hole 522. Alternatively, if the side of the lower cover 52 abuts the inner wall of the water tank 20, blocking the side water inlet hole 522, dehumidified water can still enter through the bottom water inlet hole 523. The side water inlet holes 522 may be provided with one or more (at least two), and the multiple side water inlet holes 522 are spaced apart along the circumference of the lower cover 52. Of course, in other embodiments, the water inlet 521 may also include only the bottom water inlet hole 523 or the side water inlet hole 522.

[0049] In one embodiment, the outer circumference of the upper cover 51 is provided with a snap-fitting protrusion 513, and the lower cover 52 is provided with a snap-fitting hole 524 extending through at least its inner circumference. The snap-fitting protrusion 513 snaps into the snap-fitting hole 524. Specifically, the snap-fitting hole 524 extends through both the inner and outer surfaces of the lower cover 52. The outer diameter of the upper cover 51 is smaller than the inner diameter of the lower cover 52, allowing the upper cover 51 to be inserted into the lower cover 52. The height of the snap-fitting protrusion 513 relative to the outer circumference of the upper cover 51 is greater than the clearance between the upper and lower covers 51 and 52. This allows the snap-fitting protrusion 513 to snap into the snap-fitting hole 524, securing the lower cover 52 to the upper cover 51. This simple structure facilitates assembly and disassembly of the upper and lower covers 51 and 52. Of course, in other embodiments, the outer circumference of the lower cover 52 may be provided with a snap-fit ​​protrusion 513, and the upper cover 51 may be provided with a snap-fit ​​hole 524 that at least passes through its inner circumference.

[0050] To enhance the connection reliability between the upper cover 51 and the lower cover 52, in one embodiment, the outer circumferential surface of the upper cover 51 is provided with at least two engaging protrusions 513, spaced apart along the circumference of the upper cover 51. The lower cover 52 is provided with an engaging hole 524 corresponding to each engaging protrusion 513. Specifically, there are two or more engaging protrusions 513, for example, three, four, or more. This increases the number of connection points between the upper cover 51 and the lower cover 52, ensures uniform circumferential force between the lower cover 52 and the upper cover 51, and enhances the connection reliability between the upper and lower covers 51 and 52.

[0051] In one embodiment, an insertion direction is defined, along which the upper cover 51 is inserted into the lower cover 52. A guide surface 514 is provided at the front end of the engaging protrusion 513 along the insertion direction. The guide surface 514 gradually extends obliquely toward the outer peripheral surface of the upper cover 51 in the insertion direction. During the insertion of the upper cover 51 into the lower cover 52, the guide surface 514 abuts the opening edge of the lower cover 52 before the guide surface 514 abuts the opening edge of the lower cover 52, causing the opening edge of the lower cover 52 to gradually deform outward along the guide surface 514. This prevents the front end of the engaging protrusion 513 from abutting the opening edge of the lower cover 52, which could make it difficult to insert the upper cover 51 into the lower cover 52.

[0052] When the upper cover 51 is inserted into the lower cover 52, the engaging protrusion 513 abuts against the lower cover 52 and deforms, or the engaging protrusion 513 is squeezed and deformed by the inner surface of the lower cover 52, until the engaging protrusion 513 engages the engaging hole 524. To reduce the resistance encountered when the engaging protrusion 513 engages the engaging hole 524, in one embodiment, a plurality of notches 525 are provided on the upper edge of the lower cover 52, with the engaging hole 524 located between two adjacent notches 525. Specifically, the engaging holes 524 are provided with notches 525 on opposite sides of the circumference of the lower cover 52. This increases the elasticity of the portion of the lower cover 52 where the engaging holes 524 are located, making it easier for the engaging protrusion 513 to elastically deform during engagement, reducing the resistance encountered when the engaging protrusion 513 engages the engaging hole 524, and facilitating the installation of the lower cover 52 and the upper cover 51. Of course, in other embodiments, the notch 525 may not be provided.

[0053] In one embodiment, the water extraction pipe 30 is a hose. It is understood that configuring the water extraction pipe 30 as a hose not only facilitates storage for the user but also prevents the water extraction pipe 30 from rigidly contacting the water tank 20. The water extraction pipe 30 can be configured to be longer and in contact with the bottom wall of the water tank 20 to fully extract the water from the water tank 20.

[0054] In one embodiment, the water inlet end of the drainage pump is further provided with a first connector 41, and the first connector 41 is detachably mounted on the shell 11, and the water extraction pipe 30 is connected to the first connector 41. That is, the first connector 41 is connected to the water inlet of the drainage pump. It can be understood that in this embodiment, the fuselage 10 also includes a dehumidification device provided in the shell 11, and in the working state, the dehumidified water generated by the dehumidification device can fall into the water tank 20. Optionally, the dehumidification device includes a compressor, an evaporator and a condenser, which first condenses the water vapor in the air into water droplets through the evaporator to remove the water vapor in the air, and then heats and dries the air after the water vapor is removed through the condenser to restore the blown air to normal temperature. Of course, in other embodiments, the dehumidification device can also adopt dehumidification methods such as adsorption.

[0055] When the body 10 is in operation, it extends relative to the water tank 20, so that at least a portion of the body 10 is located above the water tank 20, and the bottom of the body 10 is spaced apart from the bottom of the water tank 20. This allows the dehumidified water generated by the dehumidification device in the body 10 to drain into the water tank 20 (the body 10 can be placed entirely above the water tank 20, or the bottom portion of the body 10 can be extended into the water tank 20). The dehumidified water in the water tank 20 can be pumped out through a drain pump and discharged from the drain level. The drain pump can be activated to drain the water while the dehumidification device in the body 10 is operating, or it can be activated to drain the water from the water tank 20 after the dehumidification device in the body 10 has completed its dehumidification operation. In the operating state, the drain level can be exposed outside the water tank 20, or it can be hidden. Furthermore, a filter element 50 can be disposed between the water extraction pipe 30 and the first connector 41.

[0056] In this embodiment, the body 10 also has a non-operating state. In this non-operating state, the body 10 is at least partially contained within the water tank 20. Specifically, after the water in the water tank 20 is completely drained, the body 10 can be at least partially contained within the water tank 20, placing the body 10 in the non-operating state. When the body 10 is in the non-operating state, the body 10 can be at least partially contained within the water tank 20, lowering the dehumidifier's center of gravity and making it more stable and less likely to tip over. This also reduces the overall space occupied by the dehumidifier, making it easier for users to place the dehumidifier. When the body 10 is in the operating state, the body 10 extends relative to the water tank 20, positioning the air outlet higher. This allows the dehumidified air to be discharged at a higher position, allowing the dehumidified air to be more quickly distributed throughout the room. Of course, in other embodiments, the fuselage 10 may not have a non-working state in which it is housed in the water tank 20. For example, the fuselage 10 may always be placed on the water tank 20, or, in the non-working state, the fuselage 10 may be removed from the water tank 20, and the fuselage 10 and the water tank 20 may be stored separately.

[0057] In the technical solution of the present invention, in the operating state, the water tank 20 is externally positioned below the main body 10. Compared to the technical solution in which the water tank 20 is internally mounted on the main body 10, this technical solution allows the water tank 20 to have a larger volume, thereby accommodating more dehumidified water. Furthermore, by removably mounting the first connector 41 on the housing 11 of the main body 10, in the operating state, the first connector 41 can be installed in the mounting position 12 and connected to the water inlet of the drain pump. The upper end of the water pump pipe 30 is also connected to the first connector 41, and the lower end of the water pump pipe 30 is extended into the water tank 20, thereby allowing the water in the water tank 20 to be drained through the drain pump and the water pump pipe 30. This allows the water in the water tank 20 to be drained without moving the water tank 20 or removing the main body 10, reducing the need for users to carry the water tank 20 to empty the water. Since the first connector 41 is detachable, the first connector 41 and the water extraction pipe 30 can be easily removed from the body 10. For example, when the body 10 needs to be transported or the dehumidifier needs to be stored when it is idle, the first connector 41 and the water extraction pipe 30 can be removed to avoid interference between the first connector 41 and the water extraction pipe 30 during transportation or storage, thereby facilitating transportation and storage of the body 10.

[0058] Please refer to Figure 4 and Figure 5 In one embodiment, a mounting location 12 is provided on the side of the housing 11, and the first connector 41 is removably mounted on the mounting location 12. This is equivalent to the water extraction pipe 30 being connected to the side of the housing 11. This allows the user to easily observe the position of the mounting location 12 when removing or installing the first connector 41, making it easier for the user to align and install the first connector 41. This also facilitates the user's ability to check the connection between the first connector 41 and the mounting location 12, preventing the first connector 41 from being improperly connected or becoming detached without the user's knowledge. Of course, in other embodiments, the mounting location 12 may also be located on the chassis of the body 10.

[0059] In one embodiment, the water inlet of the drain pump is further provided with a second connector 42, which is connected to the end of the first connector 41 away from the water extraction pipe 30. Specifically, the water inlet of the drain pump is connected to the second connector 42. The second connector 42 is also mounted on the housing 11 and located inside the mounting position 12. The first connector 41 passes through the housing 11 and plugs into the second connector 42. The drain pump is located within the housing 11, and the water inlet of the drain pump is connected to the second connector 42 via the water inlet pipe. This arrangement is equivalent to connecting the drain pump and the first connector 41 via the second connector 42. This arrangement eliminates the need for the drain pump to be positioned freely within the mounting position 12. For example, the drain pump can be positioned at a suitable location within the housing 10 and then connected to the second connector 42 via the water inlet pipe. This improves the structural rationality of the housing 10 and facilitates full utilization of the space within the housing 10. The second connector 42 can be detachably or non-detachably connected to the housing 11. Furthermore, the first connector 41 can be plugged into the second connector 42, or the second connector 42 can be plugged into the first connector 41. The second connector 42 can be connected to the water inlet of the drain pump, or the second connector 42 and the water inlet of the drain pump can be connected via an inlet pipe. Of course, in other embodiments, the water inlet of the drain pump can be located inside the mounting position 12, with the first connector 41 inserted through the housing 11 and connected to the water inlet, or the first connector 41 and the water inlet of the drain pump can be connected via an inlet pipe, etc. In other embodiments, the drain pump can be located outside the housing 11. Alternatively, the second connector 42 can be located outside the housing 11.

[0060] Please refer to Figures 5 to 8 In one embodiment, the first connector 41 is rotatably engaged with the mounting position 12. Specifically, when installing the first connector 41, the first connector 41 is first inserted into the mounting position 12. Then, by rotating the first connector 41, the first connector 41 engages with the mounting position 12, thereby restricting the first connector 41 from moving straight outward from the mounting position 12. When removing the first connector 41, the first connector 41 needs to be rotated a certain angle before being removed. This ensures a secure connection for the first connector 41, preventing it from falling off. Of course, in other embodiments, the first connector 41 can also be installed in the mounting position 12 with a tight fit.

[0061] There are various structures of the mounting position 12. For example, in one embodiment, the mounting position 12 has an annular circumferential wall 122, and the annular circumferential wall 122 is provided with a limiting groove 123 and a clearance opening 124. The limiting groove 123 extends along the circumference of the annular circumferential wall 122 and is spaced from the outer edge of the annular circumferential wall 122. The clearance opening 124 passes through the groove side wall of the limiting groove 123 and the outer edge of the annular circumferential wall 122. The outer peripheral surface of the first joint 41 is provided with a limiting clamping protrusion 416, and the limiting clamping protrusion 416 is clamped into the limiting groove 123 through the clearance opening 124.

[0062] Specifically, the annular circumferential wall 122 is generally circular in shape. The outer edge of the annular circumferential wall 122, i.e., the outer surface of the housing 11, is located around the annular circumferential wall 122. The sidewalls of the retaining groove 123 extend circumferentially along the annular circumferential wall 122. The portion of the first connector 41 that extends into the annular circumferential wall 122 is generally circular (the portion of the first connector 41 that extends into the annular circumferential wall 122 may also be elliptical, polygonal, etc.). When the first connector 41 is inserted into the annular circumferential wall 122, the retaining protrusion 416 engages the retaining groove 123 from the clearance opening 124. By rotating the first connector 41, the retaining protrusion 416 moves within the retaining groove 123 along the circumferential direction of the annular circumferential wall 122 and moves to a position spaced apart from the clearance opening 124. At this point, the sidewalls of the retaining groove 123 can restrict the retaining protrusion 416 from moving outward from the mounting position 12, preventing the first connector 41 from dislodging from the mounting position 12. This ensures the reliable installation of the first connector 41. Of course, in other embodiments, a limiting rib may be provided on the annular circumferential wall 122 , the limiting rib extending along the circumference of the annular circumferential wall 122 , the limiting rib having a fracture, and the limiting latch 416 being inserted into the inner side of the limiting rib through the fracture.

[0063] In one embodiment, the mounting position 12 includes a mounting slot 121 provided on the side of the body 10, and a clearance hole 125 formed through the bottom wall of the mounting slot 121. The sidewalls of the mounting slot 121 form an annular peripheral wall 122. The first connector 41 includes a connecting tube 411 and an annular protrusion 415 protruding from the outer circumference of the connecting tube 411. The outer circumference of the annular protrusion 415 forms a limit locking protrusion 416. The annular protrusion 415 rotatably engages within the mounting slot 121, and the connecting tube 411 is inserted through the clearance hole 125.

[0064] Specifically, the mounting groove 121 is provided on the outer side surface of the shell 11, and the clearance hole 125 is connected to the inner cavity of the shell 11. The aperture of the clearance hole 125 is smaller than the diameter of the mounting groove 121. The outer edge of the annular peripheral wall 122 is the surface around the notch of the mounting groove 121. The annular protrusion 415 is located between the two ends of the connecting pipe 411. During the process of inserting the first joint 41 into the mounting position 12, one end of the connecting pipe 411 extends from the clearance hole 125 into the inner cavity of the shell 11 to communicate with the water inlet of the drainage pump, and the other end of the connecting pipe 411 is located outside the shell 11 to connect with the water pump 30. The annular protrusion 415 is inserted into the mounting groove 121 with the position of the limiting clamp 416 corresponding to the clearance opening 124, and the limiting clamp 416 extends from the clearance notch into the limiting groove 123. Then, by rotating the first joint 41 , the limiting protrusion 416 moves along the annular protrusion 415 in the limiting groove 123 along the circumference of the installation groove 121 and moves to a position spaced apart from the clearance opening 124 .

[0065] Compared to the method of providing an annular protrusion on the outer side surface of the shell 11 to form the annular circumferential wall 122, providing the mounting groove 121 on the outer side surface of the shell 11 in this manner can avoid forming a protruding structure on the outer side surface of the shell 11, thereby preventing the protruding structure from interfering with the water tank 20. It can also reduce the protruding height of the first joint 41 relative to the outer circumferential surface of the shell 11, reducing the possibility of interference between the first joint 41 and the water tank 20. In some embodiments, the end of the connecting pipe 411 connected to the water suction pipe 30 can also be arranged flush with the outer end surface of the annular protrusion 415, and the water suction pipe 30 can be inserted into the connecting pipe 411. In addition, in other embodiments, an annular rib can also be provided on the outer side surface of the shell 11, and the annular circumferential wall 122 can be formed on the inner side of the annular rib. In this embodiment, the connecting pipe 411 is plugged into the second joint 42.

[0066] In one embodiment, the outer circumferential surface of the annular protrusion 415 is provided with at least two limiting latching protrusions 416, which are spaced apart along the circumference of the annular protrusion 415. There are at least two clearance openings 124, with each limiting latching protrusion 416 correspondingly engaging with the limiting groove 123 through one clearance opening 124. The limiting groove 123 may have one or more than two. When there is only one limiting groove 123, the limiting groove 123 may be annular, with the multiple clearance openings 124 extending through the sidewall of the limiting groove 123. When there are multiple limiting grooves 123, for example, when there are two limiting grooves 123, the two limiting grooves 123 are spaced apart along the circumference of the annular circumferential wall 122, and each limiting groove 123 has a corresponding clearance opening 124. When multiple limiting protrusions 416 are provided, multiple positions along the circumference of the annular protrusion 415 are restrained, thereby increasing the installation stability of the first connector 41 and preventing the first connector 41 from loosening. The number of limiting protrusions 416 can be two, three, or four, etc., so that the multiple limiting protrusions 416 are evenly spaced along the circumference of the annular protrusion 415 to ensure uniform force at all circumferential locations of the first connector 41. Of course, in other embodiments, only one limiting protrusion 416 may be provided.

[0067] In one embodiment, the connecting pipe 411 includes a pipe joint 414, and a first tube body 412 and a second tube body 413 disposed axially on opposite sides of the annular protrusion 415. The first tube body 412 is inserted into the clearance hole 125 and plugs into the second joint 42. The pipe joint 414 is disposed on the outer circumference of the second tube body 413 and is connected to the upper end of the water extraction pipe 30. Specifically, the pipe joint 414 extends laterally toward the first tube body 412. For example, when the first joint 41 is installed, the pipe joint 414 faces downward, forming a generally L-shaped arrangement between the second tube body 413 and the pipe joint 414. This arrangement reduces the height of the second tube body 413 and the pipe joint 414 relative to the outer surface of the housing 11, thereby reducing the height of the water extraction pipe 30 relative to the outer surface of the housing 11 and further reducing the possibility of damage to the water extraction pipe 30. Of course, in other embodiments, the pipe joint 414 may not be provided, and the water pumping pipe 30 may be connected to the second pipe body 413 .

[0068] In one embodiment, the limiting latch 416 is provided with a first guide bevel 417, which is configured to guide and engage with the sidewalls of the limiting groove 123. Specifically, the first guide bevel 417 is located at the front end of the limiting latch 416 in the direction in which it rotates from the clearance opening 124 into the limiting groove 123, and is located on the surface of the limiting latch 416 facing away from the interior of the housing 11. That is, when the limiting latch 416 is inserted into the limiting groove 123, the first guide bevel 417 faces the sidewalls of the limiting groove 123. The provision of the first guide bevel 417 allows the front end of the limiting latch 416 to be at least partially spaced from the sidewalls of the limiting groove 123 after the limiting latch 416 is inserted through the clearance opening 124. This prevents interference between the front end of the limiting latch 416 and the intersection of the clearance opening 124 and the sidewalls of the limiting groove 123, ensuring smooth entry of the limiting latch 416 into the limiting groove 123.

[0069] Please refer to Figures 7 to 10 In one embodiment, the sidewall of the limiting groove 123 is provided with a second guiding bevel 126. The second guiding bevel 126 gradually extends obliquely toward the outer edge of the annular circumferential wall 122 as it approaches the clearance opening 124. The second guiding bevel 126 is used to guide and cooperate with the limiting latch 416. The provision of the second guiding bevel 126 creates a flared design at the intersection of the sidewall of the limiting groove 123 and the clearance opening 124. This prevents the front end of the limiting latch 416 from interfering with the intersection of the clearance opening 124 and the sidewall of the limiting groove 123 after the limiting latch 416 is inserted through the clearance opening 124, thereby ensuring that the limiting latch 416 smoothly enters the limiting groove 123.

[0070] Please refer to Figure 1 and Figure 4In order to reduce the possibility of water leakage between the first joint 41 and the second joint 42, in one embodiment, a sealing ring 43 is provided between the first joint 41 and the second joint 42. Specifically, the sealing ring 43 is provided in the second joint 42, and the first joint 41 is inserted into the sealing ring 43. The outer periphery of the sealing ring 43 abuts against the inner wall of the second joint 42. By providing the sealing ring 43 between the first joint 41 and the second joint 42, on the one hand, water leakage can be prevented, and on the other hand, the fitting accuracy between the first joint 41 and the second joint 42 can be reduced. Even if the gap between the first joint 41 and the second joint 42 is large, sealing can be achieved by the sealing ring 43. Among them, the number of sealing rings 43 can be one or not less than two. Of course, in other embodiments, the first joint 41 can also be inserted into the second joint 42 with interference fit.

[0071] In one embodiment, an annular receiving groove is defined on the inner wall of the second connector 42. The annular receiving groove is located at the end of the second connector 42 into which the first connector 41 is inserted. The inner diameter of the sealing ring 43 disposed in the annular receiving groove is less than or equal to the outer diameter of the sealing ring 43. The inner diameter of the second connector 42 is greater than the inner diameter of the sealing ring 43, so that when the sealing ring 43 is disposed in the annular receiving groove, the inner side of the sealing ring 43 protrudes from the inner wall of the second connector 42. The head-mounted device further includes a retaining member 44, which is mounted on the second connector 42 to confine the sealing ring 43 within the annular receiving groove and prevent the sealing ring 43 from escaping from the second connector 42. The retaining member 44 defines a clearance hole that communicates with the second connector 42, and the first connector 41 is inserted into the second connector 42 through the clearance hole.

[0072] Please refer to Figure 1 and Figure 5 To reduce interference between the water pump pipe 30 and the inner wall of the water tank 20, in one embodiment, a relief groove 13 is provided on the side of the housing 11. The relief groove 13 extends through the bottom of the housing 11, and the mounting position 12 is located at the bottom of the relief groove 13. The water pump pipe 30 extends into the water tank 20 along the relief groove 13. Specifically, the relief groove 13 is provided on the outer side of the housing 11, and the water pump pipe 30 extends downward into the water tank 20 through the relief groove 13. The provision of the relief groove 13 reduces the protrusion of the water pump pipe 30 relative to the outer side of the housing 11. This reduces the pressure exerted by the inner wall of the water tank 20 on the water pump pipe 30 when the main body 10 is in operation, thereby ensuring effective water pumping by the water pump pipe 30. This further reduces the possibility of interference between the water pump pipe 30 and the inner wall of the water tank 20, which could make it difficult to insert the main body 10 into the water tank 20, and reduces the possibility of damage to the water pump pipe 30. In addition, after the avoidance groove 13 is provided, the gap between the outer side of the housing 11 and the inner wall of the water tank 20 can be reduced, which is conducive to reducing the volume of the water tank 20 and making the overall structure of the dehumidifier more compact. Of course, in other embodiments, the avoidance groove 13 can also be omitted.
