[0027] The housing assembly 100 includes a first housing 10, a housing body 11, a mating surface 111, a protective edge 12, a second housing 20, a limiting rib 21, a handle 30, a hand-held end 31, a tail end 32, a stop point 321, a bevel 322, and an elastic element 40. Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] Combination Figure 1According to an embodiment of the present invention, a housing assembly 100 is used for a cleaning device. The housing assembly 100 includes a first housing 10 and a second housing 20. At least a portion of the second housing 20 is disposed within the first housing 10. Specifically, the entire second housing 20 may be disposed within the first housing 10, or a portion of the second housing 20 may be disposed within the first housing 10, with another portion extending out of the second housing 20. The second housing 20 is detachably connected to the first housing 10.

[0030] For example, the housing assembly 100 can be used to collect wastewater generated by cleaning equipment during floor cleaning. A first housing 10 defines a cavity for containing wastewater, and a second housing 20 can cover the cavity. The second housing 20 is detachably connected to the first housing 10, facilitating cleaning of the housing assembly 100 by the user. Of course, the housing assembly 100 of this invention can also be used to store clean water. This invention is mainly described using the housing assembly 100 as a wastewater tank for collecting wastewater, but this should not be considered a limitation on the scope of protection of this invention.

[0031] Combination Figure 2 , Figure 3 and Figure 6 The housing assembly 100 also includes a handle 30, which is rotatably connected to the second housing 20. The handle 30 has a first position and a second position. In the first position, the handle 30 is housed within the first housing 10. In the second position, the handle 30 is in an unfolded state relative to the first housing 10, allowing the user to pick it up, and is subjected to a restoring force that rotates it towards the first position. For example, the handle 30 facilitates the user's picking up and placing of the second housing 20, and also allows the user to easily clean the second housing 20 by picking up the handle 30 when cleaning the housing assembly 100. In the first position, the handle 30 is retracted into the first housing 10, facilitating the installation of the housing assembly 100 onto the cleaning equipment. In the second position, the handle 30 is in an unfolded state, and simultaneously, the handle 30 is subjected to a restoring force rotating toward the first position, so that the handle 30 can be reset to the first position when unfolded, preventing the handle 30 from interfering with the installation of the second housing 20 and the first housing 10, facilitating the docking of the second housing 20 and the first housing 10. In addition, it also facilitates the reset and retraction of the handle 30 into the first housing 10, thereby facilitating the docking of the housing assembly 100 with the cleaning equipment, and preventing the housing assembly 100 from being improperly installed due to the handle 30 not being reset, which could affect the functionality of the cleaning equipment.

[0032] For example, an elastic element 40 can be provided between the handle 30 and the second housing 20, so that when the handle 30 moves to the second position, it is always subjected to a pulling force toward the first position, which causes the handle 30 to self-reset; or, the handle 30 is provided with a hand-held end 31 and a tail end 32 distributed at both ends of the rotation shaft. When the second housing 20 is connected to the first housing 10, the tail end 32 cooperates with the first housing 10 to make the handle 30 subjected to a force toward the first position, causing the handle 30 to rotate to the first position, thereby realizing the self-reset function of the handle 30.

[0033] According to the housing assembly 100 of this utility model embodiment, when the handle 30 is in the second position, that is, the unfolded state, it is subjected to a restoring force that rotates toward the first position, which facilitates the reset of the handle 30 after unfolding, and facilitates the quick docking of the housing assembly 100 with the main body of the cleaning equipment, thereby improving the convenience of user operation.

[0034] In some embodiments of this utility model, in the second position, the handle 30 abuts against the first housing 10 and separates the first housing 10 and the second housing 20 in the vertical direction, and the reaction force on the handle 30 is suitable for driving the handle 30 to rotate towards the first position. Specifically, when the handle 30 is in the second position, by abutting against the first housing 10, the first housing 10 and the second housing 20 are separated in the vertical direction, which facilitates the removal of the second housing 20 from the first housing 10, making it convenient for the user to separate the first housing 10 and the second housing 20. Understandably, when the first housing 10 and the second housing 20 are docked, if the handle 30 remains in the second position, the handle 30 exerts a force that abuts and separates the first housing 10, which may cause the second housing 20 to fail to be installed in place. Therefore, when the handle 30 is in the second position, it is subjected to a reaction force and driven to move towards the first position. This can prevent the first housing 10 and the second housing 20 from failing to be installed in place due to the handle 30 being in the second position, thereby improving the installation efficiency of the first housing 10 and the second housing 20, and avoiding functional failure of the cleaning equipment caused by the incomplete docking of the first housing 10 and the second housing 20.

[0035] Combination Figures 2 to 4 In some embodiments of this utility model, the handle 30 has a hand-held end 31 and a tail end 32, which are respectively located on both sides of the rotation axis of the handle 30, with the rotation axis being A. The tail end 32 has a stop point 321, and in the second position, the line connecting the stop point 321 of the tail end 32 and the rotation axis forms an angle with respect to the vertical direction. Figure 4As shown, the line connecting the stop point 321 and the rotation axis A is L1, and line B shows the vertical direction. The angle between L1 and line B is α. The line connecting the stop point 321 of the tail end 32 and the rotation axis L1 has a certain angle with the vertical direction B. When the second housing 20 is connected to the first housing 10 in the vertical direction, the handle 30 is subjected to a certain rotational tangential force, which can cause the handle 30 to rotate downward to the first position, realizing the automatic reset of the handle 30, so as to avoid the second housing 20 being unable to be installed in place and improve the convenience of user use.

[0036] Furthermore, the included angle is not less than 10° and not greater than 30°. Specifically, α ≥ 10° can reduce the instability of reset caused by machining errors of the housing assembly 100 and misalignment of the first housing 10 and the second housing 20 during installation, so that when the second housing 20 and the first housing 10 are connected, the handle 30 can be stably reset to the first position. In addition, it can avoid the wear at the stop point 321 being too small. α ≤ 30° can avoid the difficulty of reset of the handle 30 when the included angle is too large. When the handle 30 is in the second position, by controlling the included angle α between the stop point 321 of the tail end 32 and the line connecting the rotation axis and the vertical direction within a reasonable range, it can be ensured that the handle 30 can be stably reset to the first position during the connection of the second housing 20 and the first housing 10, thereby improving the installation efficiency of the second housing 20 and the first housing 10.

[0037] For example, the included angle can be 12°, 15°, 17°, 20°, 22°, 25°, 27°, etc.

[0038] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the tail end 32 also has a bevel 322. The bevel 322 is configured to abut against the first housing 10 when the handle 30 rotates from the first position to the second position, and drive the second housing 20 to gradually move upward relative to the first housing 10. The abutment point 321 is located at the end of the bevel 322. Specifically, the handle 30 has a rotatable structure. The position where the handle 30 is rotatably connected to the second housing 20 can serve as a fulcrum for rotation. When the user applies force to the hand end 31, the bevel 322 of the tail end 32 can drive the second housing 20 to gradually move upward, thereby separating the second housing 20 from the first housing 10, which facilitates the user to disassemble the first housing 10 and the second housing 20.

[0039] In addition, the stop point 321 is located at the end of the inclined side 322. When the second housing 20 is connected to the first housing 10, the stop point 321 and the inclined side 322 are easy to cooperate, so that the handle 30 can be quickly reset to the first position, further improving the installation efficiency of the second housing 20 and the first housing 10.

[0040] For example, the housing assembly 100 can be used to collect wastewater generated by the cleaning equipment during the cleaning process. The housing assembly 100 needs to maintain good sealing to avoid fluid leakage and improve wastewater recycling efficiency. In related technologies, when cleaning the body and cover of the wastewater tank, the user needs to pry the cover off the body, which can easily lead to fluid spraying. This utility model, by setting a bevel 322 on the tail end 32, uses the lever principle to prevent the user from directly prying the cover off the body, thus avoiding wastewater spraying. This solves the problems of difficult disassembly of the first housing 10 and the second housing 20 and inconvenience in handling the second housing 20. In addition, the stop point 321 and the bevel 322 cooperate to facilitate the quick return of the handle 30 to the first position when the first housing 10 and the second housing 20 are connected, which is convenient and easy to store, and avoids the first housing 10 and the second housing 20 not being properly assembled due to the handle 30 not being able to return to its original position. In other words, through the above design, on the one hand, it is convenient for the user to disassemble the first housing 10 and the second housing 20, and on the other hand, it is convenient for the user to quickly install the first housing 10 and the second housing 20, solving the problem of improper installation.

[0041] Combination Figure 5 For example, the first housing 10 may include a connected housing body 11 and a protective edge 12. The housing body 11 is provided with a mating surface 111. When the handle 30 rotates from the first position to the second position, the inclined edge 322 engages with the mating surface 111, driving the second housing 20 to gradually move upward relative to the first housing 10. In addition, when the first housing 10 and the second housing 20 are aligned vertically, the handle 30 engages with the mating surface 111, facilitating the reset of the handle 30. That is, the mating surface 111 can support the tail end 32 of the handle 30, facilitating the disassembly of the first housing 10 and the second housing 20. The mating surface 111 also engages with the tail end 32 of the handle 30 to support its reset. The mating surface 111 is located on the inner side of the protective edge 12. The protective edge 12 can limit and protect the tail end 32 of the handle 30, improving the structural stability of the handle 30 and preventing problems such as pinching the hand during rotation.

[0042] In some embodiments of this utility model, in the projection along the rotation axis, the length of the hand-held end 31 relative to the rotation axis is greater than the length of the tail end 32 relative to the rotation axis. This cleverly applies the lever principle, making the power arm greater than the resistance arm, reducing the force required for the user to disassemble the first housing 10 and the second housing 20. When rotating the handle 30, the second housing 20 can be pulled out from the first housing 10, preventing sewage from being sprayed when the user directly pulls out the second housing 20 in the vertical direction, thus improving the user experience.

[0043] Combination Figure 6In some embodiments of this utility model, the housing assembly 100 further includes an elastic element 40, which is connected to the handle 30 and the second housing 20. In the second position, the elastic element 40 has an elastic force that drives the handle 30 to rotate toward the first position. Specifically, after the handle 30 is rotated from the first position to the second position, under the action of the elastic element 40, the handle 30 is always subjected to a restoring force rotating toward the first position, which can cause the handle 30 to reset and be stored in the first housing 10, facilitating quick docking of the housing assembly 100 with the cleaning equipment and preventing the housing assembly 100 from failing to install properly due to the handle 30 not resetting.

[0044] For example, the elastic element 40 may be a spring or a torsion spring.

[0045] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the second housing 20 is provided with a limiting rib 21, which is configured to restrict the rotation of the handle 30 between a first position and a second position. The limiting rib 21 can limit the rotation of the handle 30, allowing the handle 30 to rotate between the first and second positions. For example, when the handle 30 is housed in the first housing 10 at the first position, the limiting rib 21 can prevent the handle 30 from dislodging from the first position and avoid collision between the handle 30 and the first housing 10. Furthermore, when the second housing 20 is detached from the first housing 10, it facilitates keeping the handle 30 suspended above the front end of the second housing 20, making it convenient for the user to retrieve the handle 30. When the handle 30 is rotated to the second position, the limiting rib 21 can prevent the handle 30 from dislodging from the second position, thus preventing the handle 30 from failing to return to its original position. By setting the limiting rib 21 to restrict the rotation of the handle 30 between the first and second positions, the stability of the housing assembly 100 during disassembly, assembly, and use is improved.

[0046] Combination Figure 2 Furthermore, the handle 30 has a hand-held end 31 and a tail end 32, which are respectively located on both sides of the rotation axis of the handle 30. In the first position, the tail end 32 of the handle 30 abuts against the lower part of the limiting rib 21 to restrict the handle 30 from rotating in the direction away from the second position, so that the handle 30 can be stably maintained in the first position to store the handle 30 in the first housing 10, thereby facilitating the docking of the housing assembly 100 with the cleaning equipment. In addition, when the handle 30 is in the first position, the limiting rib 21 can limit the downward movement of the handle 30 to collide with the first housing 10 or the second housing 20, so that the handle 30 remains suspended from the first housing 10 and the second housing 20.

[0047] Combination Figure 3In some embodiments of this utility model, in the second position, the limiting rib 21 abuts against the side of the handle 30 and restricts the handle 30 from rotating in the direction away from the first position, so as to prevent it from leaving the second position in the direction away from the first position, which would cause the handle 30 to fail to reset. By limiting the movement of the handle 30, the reset stability of the handle 30 is improved.

[0048] In some embodiments of this utility model, the handle 30 is suspended above the first housing 10 in the first position, and the gap between the handle 30 and the first housing 10 is not less than 5 mm, which can prevent the handle 30 from colliding with the first housing 10 when it is reset and reduce the wear of the handle 30 and the first housing 10.

[0049] In some embodiments of this utility model, the housing assembly 100 is a wastewater tank, which can be used to collect wastewater generated by cleaning equipment during floor cleaning. A first housing 10 defines a cavity for containing wastewater. At least a portion of the second housing 20 extends into the first housing 10, and the second housing 20 covers the upper end of the first housing 10 to seal the cavity. The second housing 20 is detachably connected to the first housing 10, facilitating cleaning of the wastewater tank by the user. Furthermore, the second housing 20 is equipped with a handle 30, allowing the user to easily lift and rinse the second housing 20 during cleaning.

[0050] The cleaning device according to an embodiment of the present invention includes the aforementioned housing assembly 100.

[0051] For example, the cleaning equipment may be a floor scrubber, and the housing assembly 100 may be a wastewater tank for collecting wastewater generated during the operation of the cleaning equipment. The first housing 10 may define a storage cavity for storing wastewater, and at least a portion of the second housing 20 extends into the first housing 10 and the second housing 20 covers the upper end of the first housing 10 to seal the storage cavity.

[0052] Optionally, the second housing 20 and the internal water vapor separation support can be an integrated structure, which simplifies the structure of the housing assembly 100 and reduces the component cost.

[0053] In addition, the handle 30 is rotatably connected to the second housing 20, that is, the handle 30 is a rotating structure. The handle 30 can be installed on the rotating shaft of the left and right symmetrical screw columns of the second housing 20, and the handle 30 is prevented from coming off by the screw limit.
