Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and more specifically, to a cleaning equipment body and a cleaning equipment. Background Technology

[0002] In the current field of cleaning equipment technology, especially in vacuum cleaner design, the disassembly and installation of the rear cover has always been a critical aspect of user operation and equipment maintenance. Traditional vacuum cleaner rear covers typically employ complex screw or clip-on structures, requiring users to perform tedious operations such as using screwdrivers or repeatedly trying to locate specific clip positions before successful disassembly and reassembly. This design not only increases the difficulty of operation and reduces the user experience but may also lead to structural wear due to frequent disassembly and reassembly, affecting the stability and lifespan of the equipment. Utility Model Content

[0003] In view of this, the purpose of this disclosure is to provide a cleaning device body and a cleaning device to solve the problem that the disassembly and assembly structure of the rear shell of a vacuum cleaner is complicated and inconvenient to operate.

[0004] To achieve the above objectives, the technical solution provided in this disclosure is as follows:

[0005] A cleaning device body includes: a main body having a receiving cavity; a rear shell detachably connected to the main body and sealing the motor end opening of the main body; a mounting base disposed within the receiving cavity; a locking mechanism disposed on the mounting base and having a locked position and an unlocked position, wherein pressing the rear shell along the length direction of the main body operates the locking mechanism to switch between the locked and unlocked positions, and the direction of disassembly and assembly of the rear shell is consistent with the direction of pressing; and a limiting structure disposed on the mounting base; wherein, when the locking mechanism is in the locked position and locks the rear shell, the rear shell limits the limiting structure, and the limiting structure abuts against the main body; when the locking mechanism is in the unlocked position and unlocks the rear shell, the rear shell releases the limiting structure, and the limiting structure releases the limiting abutment against the main body.

[0006] This disclosure employs a method of pressing the rear shell along the length of the machine body to switch the locking mechanism between locked and unlocked positions. The limiting structure and the locking mechanism are linked. When the locking mechanism is in the locked position, the limiting structure maintains a limiting contact with the machine body under the limiting action of the rear shell, and the rear shell is fixed to the machine body through the limiting structure and the locking mechanism. When the locking mechanism is in the unlocked position, the limiting structure releases its limiting contact with the machine body, and the rear shell, mounting base, and machine body can be detached. The main structure of the cleaning equipment of this disclosure is simple, and the rear shell can be quickly disassembled and assembled by simply pressing it, which is convenient and improves the user experience. Furthermore, the disassembly and assembly direction of the rear shell is consistent with the length direction of the machine body, which can avoid interference between the rear shell and the machine body during the disassembly process and ensure the smooth disassembly and assembly of the rear shell.

[0007] In some embodiments, the direction of disassembly and assembly of the rear shell is perpendicular to the direction of movement of the limiting structure. The direction of movement of the limiting structure disclosed herein is perpendicular to the direction of disassembly and assembly of the rear shell, facilitating the movement of the limiting structure toward or away from the machine body and improving operational convenience.

[0008] In some embodiments, the locking mechanism is located in the central region of the mounting base, and the limiting structure is spaced apart from the locking mechanism. The limiting end of the limiting structure can extend or retract relative to the outer periphery of the mounting base. By placing the locking mechanism in the central region of the mounting base, a uniform locking force is provided to the rear shell, which also facilitates the even distribution of the pressing force applied by the operator, ensuring the balance and stability of the rear shell during installation and disassembly. The telescopic design of the limiting structure allows it to move freely in the locked and unlocked states, thereby achieving effective fixing and release of the rear shell. This arrangement also avoids interference between the mounting base and the main body, facilitating the disassembly of the mounting base and the main body when needed.

[0009] In some embodiments, there are multiple limiting structures, which are spaced apart circumferentially along the body. These limiting structures engage with different positions on the body, and the locking mechanism is located between the multiple limiting structures. Using multiple limiting structures to engage with different positions on the rear shell increases the contact points between the rear shell and the body, thereby improving the overall structural stability and strength. Using multiple limiting structures on the outer periphery of the locking mechanism leverages their distribution to achieve more uniform force transmission, ensuring smooth locking and unlocking actions, and also avoiding interference in the movement paths between the limiting structures and the locking mechanism.

[0010] In some embodiments, the limiting structure has a body limiting end and an operating push end. The operating push end is positioned near the center of the mounting base relative to the body limiting end. The operating push end pushes against the rear shell, and the body limiting end abuts against or releases the limiting contact with the body. The two ends of the limiting structure are respectively configured to cooperate with the body and the rear shell. The rear shell can drive the limiting structure to move by actuating against the operating push end, thereby achieving limiting or unlocking with the body, reducing operational difficulty and improving user experience.

[0011] In some embodiments, the limiting structure includes a slider having a body limiting end and an operating push end; and an elastic element disposed between the slider and the mounting base, the elastic element providing a driving force for the slider to move toward the center of the mounting base. The introduction of the elastic element allows the limiting structure to automatically reset when no external force is applied, ensuring the safety of the device in non-use mode. This disclosure employs a structure where the slider and elastic element work together to achieve position switching of the limiting structure simply by pressing the rear shell, improving the linkage of the structural setup. The elimination of the need for separate operation of the limiting structure simplifies the operation and enhances the operator's experience.

[0012] In some embodiments, the slider has a clearance hole, at least a portion of the elastic element is disposed inside the clearance hole, the mounting base has a baffle extending into the clearance hole, one end of the elastic element pushes against the inner wall of the clearance hole, and the other end of the elastic element pushes against the surface of the baffle facing the center of the mounting base. By disposing the elastic element inside the clearance hole, not only is the installation space optimized and the structural compactness improved, but it also facilitates the protection of the elastic element. Furthermore, the baffle disposed inside the clearance hole has the effect of limiting the movement stroke of the slider. The arrangement of the clearance hole on the slider in conjunction with the mounting elastic element and the baffle in this disclosure ensures the stability and accuracy of the movement of the limiting structure.

[0013] In some embodiments, the mounting base has a radially extending groove, and at least a portion of the limiting structure is slidably disposed within the groove; and / or the mounting base also has a limiting member disposed at the opening of the groove for restricting the movement of the limiting structure along the length direction of the body. The groove design of this disclosure provides a precise movement trajectory for the limiting structure, ensuring its stability and accuracy during locking and unlocking; and / or the use of the limiting member ensures that the limiting structure can only move radially on the mounting base, thereby guaranteeing that after moving towards the body, the limiting structure can engage with the body for limiting abutment, avoiding misalignment along the length direction of the body that would prevent engagement with the body, and improving the overall stability of the structure.

[0014] In some embodiments, the mounting base has a mounting groove, at least a portion of the locking mechanism is accommodated within the mounting groove, and the locking mechanism is a push-button self-locking spring-loaded latch. The locking mechanism is disposed in the mounting groove, and by having at least a portion of the locking mechanism embedded within the mounting base, it helps ensure the stability of the locking mechanism installation and its protective effect, improves the stability of the locking mechanism switching between the locked and unlocked positions, and enhances operational efficiency.

[0015] In some embodiments, the rear cover has a first push-top and a second push-top on the side surface facing the mounting base. The first push-top cooperates with the locking mechanism to drive the locking mechanism to switch between a locked position and an unlocked position. The operating push-top of the limiting structure and the second push-top separate during the switching process of the locking mechanism from the locked position to the unlocked position. This disclosure adopts a double push-top design, making the disassembly and assembly of the rear cover smoother and more natural. The cooperation between the first push-top and the locking mechanism enables rapid switching of the locked state; while the interaction between the second push-top and the limiting structure ensures smooth ejection of the rear cover after unlocking. During use, the user only needs to apply pressure once to complete the entire process from locking to unlocking and then to the ejection of the rear cover, greatly simplifying the operation steps and improving the efficiency of use.

[0016] In some embodiments, when the rear cover is pressed, during the switching process of the locking mechanism from the unlocked position to the locked position, the second pusher pushes the operating pusher of the limiting structure, causing the body limiting end of the limiting structure to switch to a state of contact with the body limiting end, and the second pusher remains in contact with the operating pusher. This design ensures that when the rear cover is reinstalled, the limiting structure can accurately form a limiting engagement with the body, thereby stabilizing the position of the rear cover. In actual operation, when the user presses the rear cover, the pushing action of the second pusher causes the body limiting end of the limiting structure to form a firm contact with the body, ensuring that the rear cover remains stable even during vibrations generated during device operation, without loosening or falling off.

[0017] In some embodiments, the operating push tip has a first push surface, which is inclined relative to the plane containing the motor end opening and is positioned towards the periphery of the body relative to the center area of ​​the rear cover. The second push tip has a second push surface that mates with the first push surface. This design of the inclined first and second push surfaces utilizes the mechanical principle of inclined planes, so that when the rear cover is pressed, the pressing force along the length of the body is converted into a radial force, allowing the second push tip to push the operating push tip of the limiting structure with less effort, thereby achieving quick unlocking or locking of the rear cover.

[0018] In some embodiments, the rear housing includes an end plate for sealing the motor end opening; and a surrounding plate disposed on the periphery of the end plate and extending along the length of the body toward the interior of the receiving cavity, forming a mounting cavity. The surrounding plate has a through hole communicating with the mounting cavity, and the mounting base is disposed inside the mounting cavity. The body limiting end of the limiting structure can pass through the through hole and abut against the body limiting structure or retract into the interior of the mounting cavity through the through hole. The combined design of the end plate and the surrounding plate provides precise positioning and installation space for the mounting base and the limiting structure. The through hole on the surrounding plate provides clearance for the limiting structure. When the locking mechanism is in the locked position, the limiting structure passes through the through hole. At this time, the mounting base and the rear housing form a whole and abut against the body limiting structure. The structural design of the surrounding plate helps to improve the stability of the connection between the body, the mounting base, and the rear housing.

[0019] In some embodiments, one of the enclosure and the mounting base has a limiting groove extending along the length of the body, and the other has a limiting protrusion, at least a portion of which is slidably disposed within the limiting groove along its extension. The mating design of the limiting groove and the limiting protrusion provides additional guidance and limiting for the rear cover, ensuring precise alignment of the rear cover during installation and avoiding installation difficulties or damage caused by misalignment.

[0020] Another embodiment of this disclosure provides a cleaning device, which includes a suction head, a motor, and the aforementioned main body. The suction head is mounted on the main body for vacuuming, and the motor is located inside a accommodating cavity and protrudes through an opening at the motor end. The structural design of this disclosure allows for quick assembly and disassembly of the rear shell by pressing it, improving the efficiency of assembling and disassembling the main body of the cleaning device, thereby increasing the overall efficiency of the cleaning device. It also facilitates subsequent maintenance and replacement of the motor, simplifying the operator's workflow. The simple pressing of the rear shell further enhances the product's usability and reliability, significantly improving the overall performance and user satisfaction of the cleaning device.

[0021] This disclosure has the following beneficial effects:

[0022] This disclosure employs a method of pressing the rear shell along the length of the machine body to switch the driving locking mechanism between the locked and unlocked positions. The limiting structure and locking mechanism of this disclosure are linked, so that when the locking mechanism is in the locked position, the limiting structure maintains a limiting contact with the machine body under the limiting action of the rear shell, and the rear shell is fixed to the machine body through the limiting structure and locking mechanism. When the locking mechanism is in the unlocked position, the limiting structure releases its limiting contact with the machine body, and the rear shell, mounting base, and machine body can be detached. The main structure of the cleaning equipment of this disclosure is simple, and disassembly and assembly can be completed simply by pressing the rear shell, making operation convenient and improving the user experience. This disclosure solves the problem of inconvenient operation caused by the complex disassembly and assembly structure of the rear shell in existing cleaning equipment. Attached Figure Description

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0043] The technical solutions in this disclosure will now be described with reference to the accompanying drawings.

[0044] To address the problem that the rear shell of existing vacuum cleaners has a complex disassembly and assembly structure that makes operation inconvenient, this disclosure provides a cleaning device.

[0045] The cleaning equipment disclosed herein is a cleaning equipment with an adsorption function.

[0046] Specifically, the cleaning equipment disclosed herein can be a vacuum cleaner, or of course, other equipment.

[0047] In this embodiment, the cleaning device includes at least a cleaning device body, a suction head, and a motor. The suction head is disposed on the body of the cleaning device body for vacuuming, and the motor is disposed inside the accommodating cavity of the cleaning device body for providing suction force to the cleaning device.

[0048] In this embodiment, the main body of the cleaning equipment includes a body and a rear cover 10 covering the body. One end of the body along its length has a motor end opening that exposes the motor. The rear cover 10 is detachably mounted on the motor end opening by pressing, and can seal the motor end opening when the rear cover 10 is installed on the body. During the assembly of the cleaning equipment, the rear cover 10 can be quickly disassembled and assembled by pressing, which not only improves the efficiency of disassembling and assembling the body and the rear cover 10, but also simplifies the operator's workflow when it is necessary to install, repair, or replace internal components of the body, such as the motor, by pressing the rear cover 10 through the motor end opening. This improves the efficiency of the assembly and maintenance of the cleaning equipment, enhances the usability and reliability of the product, and significantly improves the overall performance and user satisfaction of the cleaning equipment.

[0049] The main body of the cleaning equipment disclosed herein adopts a design that allows the rear shell 10 to be installed or removed from the main body simply by pressing the rear shell 10, eliminating the need for tools and simplifying the operation process; it also avoids the problem of the service life and stability of the main body of the cleaning equipment being affected by the repeated use of fasteners such as bolts.

[0050] like Figures 1 to 10 As shown, the main body of the cleaning equipment includes a body, a rear shell 10, a mounting base 20, a locking mechanism 40, and a limiting structure 50. The body has a receiving cavity, and the end of the body has a motor end opening that communicates with the receiving cavity. The rear shell 10 is detachably connected to the body and seals the motor end opening of the body. The mounting base 20 is disposed in the receiving cavity, and the locking mechanism 40 and the limiting structure 50 are disposed on the mounting base 20. The mounting base 20 provides support for the locking mechanism 40 and the limiting structure 50. The rear shell 10 in this disclosure is disassembled and assembled by pressing, which is simple to operate and can achieve quick disassembly and assembly, which is beneficial to improving the user experience.

[0051] Specifically, the locking mechanism 40 has a locked position and an unlocked position. Pressing the rear cover 10 along the length of the body operates the locking mechanism 40 to switch between the locked and unlocked positions. The disassembly and assembly direction of the rear cover 10 is consistent with the pressing direction and is also set along the length of the body. The disassembly and assembly direction of the rear cover 10 of this disclosure is consistent with the length of the body, thereby achieving disassembly and assembly by pressing the rear cover 10, which simplifies the overall operation. Moreover, when disassembling and assembling the rear cover 10, moving along the length of the body avoids interference between the rear cover 10 and the body that may occur during the disassembly and assembly process, ensuring the smooth disassembly and assembly of the rear cover 10.

[0052] In this embodiment, as Figures 6 to 10 As shown, when the locking mechanism 40 is in the locked position and locks the rear shell 10, the rear shell 10 limits the limiting structure 50, and the limiting structure 50 abuts against the body.

[0053] When the locking mechanism 40 is in the locked position, the locking mechanism 40 locks the rear shell 10 so that the rear shell 10 and the mounting base 20 form a single mounting unit. The limiting structure 50 abuts against the body to fix the mounting base 20 and the body relatively. Under the limiting action of the rear shell 10 on the limiting structure 50, the limiting structure 50 remains in abutting against the body. At this time, the rear shell 10 forms a fixed connection with the body through the mounting base 20.

[0054] It is understood that the limiting structure 50 abuts against the body along the length of the body, that is, the movement of the limiting mechanism is restricted by the abutment along the length of the body. This disclosure achieves the limitation of the limiting structure 50 in the length direction of the body through the limiting abutment. Specifically, there is a limiting rib on the inner circumferential surface of the body, and the end of the limiting structure 50 abuts against the bottom surface of the limiting rib, so as to restrict the movement of the limiting structure 50 toward the motor end opening side by means of the limiting rib. The bottom surface of the mounting base 20 abuts against the motor, and the motor and the limiting rib form a form-fitting fixed mounting base 20, so that the mounting base 20 is relatively fixed to the body by the limiting structure 50.

[0055] In addition to the aforementioned use of limiting ribs for limiting and abutting the limiting structure 50, a corresponding groove structure communicating with the accommodating cavity can also be set on the body. When the locking mechanism 40 is in the locked position and locks the rear shell 10, the end of the limiting structure 50 extends into the interior of the groove structure to achieve limiting and abutting of the limiting structure 50 by the body.

[0056] In this embodiment, as Figures 1 to 5 As shown, when the locking mechanism 40 is in the unlocked position and the rear shell 10 is unlocked, the rear shell 10 releases its restriction on the limiting structure 50, and the limiting structure 50 releases its restriction contact with the body.

[0057] When the locking mechanism 40 is in the unlocked position, the locking mechanism 40 is unlocked from the rear shell 10 and can be separated. At this time, the rear shell 10 can be separated from the mounting base 20, and the rear shell 10 no longer limits the limiting structure 50. Therefore, the limiting structure 50 can be released from the limiting contact with the body. At this time, both the rear shell 10 and the mounting base 20 can be detached from the body.

[0058] In this embodiment, to facilitate the automatic disengagement of the rear shell 10 from the locking mechanism 40 when it is in the unlocked position, the cleaning device further includes a spring 30. The spring 30 is disposed between the mounting base 20 and the rear shell 10. The spring 30 provides elastic force to the rear shell 10 along the length of the machine body away from the mounting base 20. Multiple springs 30 can be provided, spaced apart circumferentially along the machine body. This multiple elastic arrangement helps to increase the elastic force and improve the uniformity of the elastic force on the rear shell 10, ensuring that the rear shell 10 stably disengages from the locking mechanism 40. Of course, it is not limited to using a spring 30; other structural components that can provide elastic force can also be used.

[0059] This disclosure uses the method of pressing the rear shell 10 along the length of the machine body to switch the locking mechanism 40 between the locked and unlocked positions. The limiting structure 50 and the locking mechanism 40 of this disclosure adopt a linkage structure, so that the rear shell 10 can be fixed to the machine body or can be removed from the machine body. The main structure of the cleaning equipment of this disclosure is simple, and the rear shell 10 can be quickly disassembled and assembled by simply pressing the rear shell 10, which is convenient to operate and helps to improve the user experience.

[0060] like Figure 3 As shown, the mounting base 20 of this disclosure has a mounting groove 210, and at least a portion of the locking mechanism 40 is accommodated in the mounting groove 210.

[0061] Specifically, the locking mechanism 40 is disposed in the mounting groove 210. At least a portion of the locking mechanism 40 is embedded inside the mounting base 20, which helps to ensure the stability of the installation of the locking mechanism 40 and the protective effect of the locking mechanism 40, improves the stability of the locking mechanism 40 when switching between the locked position and the unlocked position, and improves the operating efficiency.

[0062] In this embodiment, the locking mechanism 40 is located in the central region of the mounting base 20, and the limiting structure 50 is spaced apart from the locking mechanism 40.

[0063] The locking mechanism 40 is positioned in the central area of ​​the mounting base 20 to ensure that the locking mechanism 40 provides a uniform locking force to the rear shell 10. This also helps to evenly distribute the pressing force applied by the operator, ensuring the balance and stability of the rear shell 10 during installation and disassembly.

[0064] like Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the rear shell 10 of this disclosure has a first push-top 111 protruding on the side surface facing the mounting base 20. The first push-top 111 cooperates with the locking mechanism 40 to drive the locking mechanism 40 to switch between the locked position and the unlocked position.

[0065] The first push top 111 switches between the locked and unlocked positions of the locking mechanism 40 via the push locking mechanism 40. When the locking mechanism 40 is in the locked position, the locking arm of the locking mechanism 40 clamps and locks the first push top 111. When the locking mechanism 40 is in the unlocked position, the locking arm unfolds and releases the clamping and locking of the first push top 111. The cooperation between the first push top 111 and the locking mechanism 40 realizes the rapid switching of the locked state.

[0066] Specifically, the outer peripheral surface of the first push top 111 has a mating structure that engages with the locking arm of the locking mechanism 40. This mating structure can be an abutment surface extending circumferentially along the first push top 111 and parallel to the end plate 110. When the locking mechanism 40 is in the locked position, the locking arm clamps the first push top 111 and partially abuts against the abutment surface to lock the first push top 111. Alternatively, the mating structure can be a groove on the outer peripheral surface of the first push top 111. When the locking mechanism 40 is in the locked position, the locking arm clamps the first push top 111 and partially extends into the groove to lock the first push top 111. The specific structure and dimensions of the first push top 111 can be adapted to the locking mechanism 40 to achieve locking and unlocking with it.

[0067] In this embodiment, the locking mechanism 40 is a push-type self-locking spring-loaded latch. The push-type self-locking spring-loaded latch can achieve rapid position switching by pressing the first push top 111, which is beneficial to improving the efficiency of use.

[0068] The locking mechanism 40 of this disclosure is located in the central region of the mounting base 20, and the corresponding first push top 111 is located in the central region of the rear shell 10. By setting the locking mechanism 40 in the central region of the mounting base 20, it is ensured that the locking mechanism 40 provides a uniform locking force to the rear shell 10, and it is also beneficial to evenly distribute the pressing force applied by the operator, so as to ensure the balance and stability of the rear shell 10 during the installation and disassembly process.

[0069] The limiting structure 50 can be a single unit; it should be understood that it can also be as follows: Figure 5 and Figure 10 As shown, there are multiple limiting structures 50, which are spaced apart along the circumference of the machine body. The multiple limiting structures 50 are matched with different positions of the machine body for limiting, and the locking mechanism 40 is located between the multiple limiting structures 50.

[0070] In this disclosure, multiple limiting structures 50 are used in conjunction with the rear shell 10 at different positions, which can increase the contact points between the rear shell 10 and the body, thereby improving the stability and strength of the overall structure. By using multiple limiting structures 50 on the outer periphery of the locking mechanism 40, the distribution advantage of the limiting structures 50 can be utilized to achieve more uniform force transmission, ensuring smooth locking and unlocking actions, and also avoiding the problem of motion path interference between the limiting structures 50 and the locking mechanism 40.

[0071] Specifically, multiple limiting structures 50 are equally spaced along the circumference of the body. In one specific embodiment, three limiting structures 50 are provided, and the three limiting structures 50 are equally spaced along the circumference of the body. The rear shell 10 is equally spaced along the circumference of the body to form three positions that cooperate with the limiting structures 50.

[0072] In this embodiment, the movement direction of the limiting structure 50 is perpendicular to the disassembly and assembly direction of the rear shell 10, so as to facilitate the limiting structure 50 to extend or retract toward the machine body and improve the convenience of operation.

[0073] Specifically, the limiting structure 50 is slidably disposed on the mounting base 20, the mounting base 20 has a radially extending groove 220, at least a part of the limiting structure 50 is slidably disposed inside the groove 220. During the disassembly and assembly of the rear shell 10, the limiting structure 50 is slidably disposed in the groove 220 under the drive of the rear shell 10, and can slide to the end and abut against the body limit under the pushing and limiting action of the rear shell 10.

[0074] The design of the slide 220 disclosed herein provides a precise movement trajectory for the limiting structure 50, ensuring its stability and accuracy during locking and unlocking.

[0075] In this embodiment, the mounting base 20 also has a limiting member disposed at the opening of the groove 220, used to restrict the movement of the limiting structure 50 along the length direction of the machine body. This disclosure uses a limiting member to ensure that the limiting structure 50 can only move radially on the mounting base 20, thereby ensuring that the limiting structure 50 can make limiting contact with the machine body after moving towards the machine body. This avoids the phenomenon of misalignment along the length direction of the machine body, which would prevent the limiting contact from occurring, thus improving the stability of the overall structure.

[0076] like Figure 5 and Figure 10 As shown, the limiting structure 50 has a body limiting end 512 and an operating push end 511. The operating push end 511 is positioned near the center of the mounting base 20 relative to the body limiting end 512. The operating push end 511 pushes against the rear shell 10, and the body limiting end 512 abuts against or releases the limiting contact with the body limiting end.

[0077] The two ends of the limiting structure 50 are respectively configured to cooperate with the body and the rear shell 10. The rear shell 10 can drive the limiting structure 50 to move by pushing the top end 511 through the driving abutment operation, so as to realize the limiting end 512 of the body abutting or releasing the limiting abutment with the body, which reduces the difficulty of operation and improves the user experience.

[0078] Specifically, the limiting structure 50 and the locking mechanism 40 are spaced apart, and the body limiting end 512 of the limiting structure 50 can extend or retract relative to the outer periphery of the mounting base 20.

[0079] In this embodiment, when the locking mechanism 40 of the back cover 10 is pressed to switch from the unlocked position to the locked position, the body limiting end 512 can extend relative to the outer periphery of the mounting base 20 and form a limiting abutment with the body; when the locking mechanism 40 of the back cover 10 is pressed to switch from the locked position to the unlocked position, the limiting abutment between the body limiting end 512 and the body is released, and it retracts to the inside of the outer periphery of the mounting base 20.

[0080] During the installation of the rear cover 10, pressing the rear cover 10 causes the push-top 511 of the rear cover 10 to drive the limiting structure 50 to slide in the radial direction of the body towards the body. When the body limiting end 512 of the limiting structure 50 abuts against the body's limiting end, the rear cover 10 is installed, and the locking mechanism 40 is in the locked position.

[0081] like Figure 9 As shown, the rear shell 10 uses a pushing method to limit the limiting structure 50 so that the limiting structure 50 can remain in contact with the body.

[0082] Specifically, the rear cover 10 has a raised second push top 112 on the side surface facing the mounting base 20. The operating push top 511 of the limiting structure 50 and the second push top 112 are separated from each other during the process of the locking mechanism 40 switching from the locked position to the unlocked position.

[0083] When the back cover 10 is pressed, during the process of the locking mechanism 40 switching from the unlocked position to the locked position, the second push top 112 pushes the operating push top 511 of the limiting structure 50 so that the body limiting end 512 of the limiting structure 50 switches to the state of abutting against the body limiting end, and the second push top 112 remains in the state of abutting against the operating push top 511.

[0084] This design ensures that when the rear cover 10 is reinstalled, the limiting structure 50 can accurately form a limiting fit with the machine body, thereby stabilizing the position of the rear cover 10. In actual operation, when the user presses the rear cover 10, the pushing action of the second push top 112 will cause the machine body limiting end 512 of the limiting structure 50 to form a firm contact with the machine body. Even during the vibration generated by the operation of the equipment, the rear cover 10 can remain stable and will not loosen or fall off.

[0085] In this embodiment, the operating push tip 511 has a first push surface 5111, which is inclined relative to the plane where the motor end opening is located, and is positioned towards the periphery of the body relative to the center area of ​​the rear cover 10. The second push tip 112 has a second push surface 113 that cooperates with the first push surface 5111. This design of the inclined first push surface 5111 and second push surface 113 utilizes the mechanical principle of inclined planes, so that when the rear cover 10 is pressed, the pressing force along the length of the body is converted into a radial force, so that the second push tip 112 can push the operating push tip 511 of the limiting structure 50 with less effort, thereby realizing the quick unlocking or locking of the rear cover 10.

[0086] This disclosure employs a double-push design, with a first push-top 111 and a second push-top 112 working together. This makes the disassembly and assembly of the rear cover 10 smoother and more natural. The cooperation between the first push-top 111 and the locking mechanism 40 enables rapid switching between locked and unlocked states. Meanwhile, the interaction between the second push-top 112 and the limiting structure 50 ensures the smooth ejection of the rear cover 10 after unlocking. During use, the user only needs to apply a single press to complete the entire process from locking to unlocking and then to the ejection of the rear cover 10, greatly simplifying the operation and improving efficiency.

[0087] In this embodiment, the movement of the limiting structure 50 toward the body is achieved by the pushing of the rear shell 10, and the movement of the limiting structure 50 toward the direction away from the body is achieved by its own elastic force.

[0088] Specifically, such as Figure 4 and Figure 9 As shown, the limiting structure 50 includes a slider 510 and an elastic element 520. The slider 510 has a body limiting end 512 and an operating push end 511. The elastic element 520 is disposed between the slider 510 and the mounting base 20. The elastic element 520 provides driving force for the slider 510 to move toward the center of the mounting base 20. The elastic element 520 is a spring.

[0089] When the back cover 10 is pressed to switch from the unlocked position to the locked position, the push-top 511 of the back cover 10 drives the body limiting end 512 of the slider 510 to move toward the body. When the back cover 10 is pressed to switch from the locked position to the unlocked position, the slider 510 moves toward the center of the mounting base 20 under the drive of the elastic element 520. The structure of slider 510 and elastic element 520 working together enables the position switching of the limiting structure 50 by pressing the back cover 10 alone. The linkage of the structure provides simplification of operation without the need for separate operation of the limiting structure 50, which is conducive to improving the operator's experience.

[0090] In this embodiment, the specific structure of the elastic member 520 and the sliding is configured such that the slider 510 has a clearance hole 5101, at least a portion of the elastic member 520 is disposed inside the clearance hole 5101, the mounting base 20 has a baffle 230 extending into the clearance hole 5101, one end of the elastic member 520 pushes against the inner wall of the clearance hole 5101, and the other end of the elastic member 520 pushes against the surface of the baffle 230 facing the center of the mounting base 20.

[0091] By setting the elastic element 520 inside the clearance hole 5101, not only is the installation space optimized and the compactness of the structure improved, but it is also beneficial to protect the elastic element 520. Furthermore, the baffle 230 set inside the clearance hole 5101 has the effect of limiting the movement stroke of the slider 510. The arrangement structure of setting the clearance hole 5101 on the slider 510 in conjunction with the installation of the elastic element 520 and the baffle 230 ensures the stability and accuracy of the movement of the limiting structure 50.

[0092] like Figure 4 and Figure 9 As shown, the rear shell 10 includes an end plate 110 and a surrounding plate 120. The end plate 110 is used to block the motor end opening. The surrounding plate 120 is disposed on the periphery of the end plate 110 and extends towards the inside of the accommodating cavity along the length direction of the body. The surrounding plate 120 forms a mounting cavity. The surrounding plate 120 has a through hole 121 communicating with the mounting cavity. The through hole 121 is configured to correspond one-to-one with the limiting structure 50. The mounting base 20 is disposed inside the mounting cavity. The body limiting end 512 of the limiting structure 50 can pass through the through hole 121 to abut against the body limiting end or retract into the mounting cavity through the through hole 121.

[0093] The end face of the end plate 110 facing away from the enclosure 120 is a pressing surface, which allows the operator to drive the rear shell 10 to move along the length of the machine body. The surface of the end plate 110 facing the receiving cavity has a first push top 111 and a second push top 112.

[0094] Specifically, during the process of switching the locking mechanism 40 from the unlocked position to the locked position by pressing the back cover 10, the limiting structure 50 moves from the inside of the mounting cavity toward the body side. When the body limiting end 512 of the limiting structure 50 moves to the through hole 121 and abuts against the body limiting, the locking mechanism 40 switches to the locked position. At this time, part of the limiting structure 50 is located inside the mounting cavity, and part is located outside the mounting cavity. The part located outside the mounting cavity abuts against the body limiting.

[0095] Since the limiting structure 50 passes through the through hole 121, the limiting structure 50 and the through hole 121 work together to limit the rear shell 10's enclosure plate 120 along the length of the body, so that the rear shell 10 cannot detach along the length of the body. At the same time, the locking mechanism 40 locks the rear shell 10. Under this double-fixed structure, the stability of the rear shell 10 installation is further enhanced. At the same time, the through hole 121 on the enclosure plate 120 also has the function of limiting the rear shell 10 along the circumference of the body, which can prevent the rear shell 10 from rotating and further improve the stability of the rear shell 10.

[0096] Specifically, during the process of switching the locking mechanism 40 from the locked position to the unlocked position by pressing the rear shell 10, the portion of the limiting structure 50 located outside the mounting cavity retracts into the mounting cavity through the through hole 121. The limiting structure 50 releases its limiting contact with the body. At this time, the limiting structure 50 can no longer limit the enclosure 120 of the rear shell 10 along the length direction of the body through the through hole 121, and the locking mechanism 40 is unlocked from the rear shell 10. At this time, the rear shell 10 can be disassembled from the body along the length direction of the body to complete the disassembly of the rear shell 10.

[0097] In one embodiment of this invention, the enclosure 120 has a limiting groove 240 extending along the length of the body, and the mounting base 20 has a limiting protrusion, at least a portion of which is slidably disposed inside the limiting groove 240 along the extension of the limiting groove 240.

[0098] In another embodiment of this example, the mounting base 20 has a limiting groove 240 extending along the length direction of the body, and the surrounding plate 120 has a limiting protrusion, at least a portion of which is slidably disposed inside the limiting groove 240 along the extension of the limiting groove 240.

[0099] This disclosure provides additional guidance and limiting functions for the rear housing 10 through the cooperative design of the limiting groove 240 and the limiting protrusion, ensuring the precise alignment of the rear housing 10 during installation and avoiding installation difficulties or damage caused by misalignment.

[0100] This disclosure has the following beneficial effects:

[0101] This disclosure uses a method of pressing the rear shell 10 along the length of the machine body to switch the locking mechanism 40 between the locked and unlocked positions. The limiting structure 50 and the locking mechanism 40 are linked, so that when the locking mechanism 40 is in the locked position, the limiting structure 50 maintains a limiting contact with the machine body under the limiting action of the rear shell 10. The rear shell 10 is fixed to the machine body through the limiting structure 50 and the locking mechanism 40. When the locking mechanism 40 is in the unlocked position, the limiting structure 50 releases its limiting contact with the machine body, and the rear shell 10, mounting base 20, and machine body can be detached. The main structure of the cleaning equipment of this disclosure is simple, and disassembly and assembly can be completed simply by pressing the rear shell 10, making operation convenient and improving the user experience. This disclosure solves the problem of inconvenient operation caused by the complex disassembly and assembly structure of the rear shell 10 in existing cleaning equipment.
