Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning and dust removal, and in particular, to a cleaning device. Background Art

[0002] With the continuous improvement of living standards, people's requirements for living and working environments are getting higher and higher. In order to ensure that the environment has a good cleanliness, cleaning equipment has emerged to clean various places or objects. The use of cleaning equipment not only reduces the labor cost of cleaning work, but also improves the efficiency of cleaning work.

[0003] Some cleaning devices include a body and a dust cup, and the dust cup is releasably fixed to the body by a locking mechanism. During operation, a suction source generates negative pressure to suck in air and dust, and then collects the dust in the dust cup to achieve the purpose of cleaning. When a lot of dust accumulates in the dust cup, the user can release the dust cup by operating the locking mechanism to remove the dust cup from the body, and then empty the dust in the dust cup.

[0004] However, for traditional cleaning equipment, the locking mechanism is not only complex in structure but also difficult to operate. Summary of the invention

[0005] In view of this, the present disclosure provides a cleaning device, aiming to improve the problem that the locking mechanism of the traditional cleaning device is relatively complicated and difficult to operate.

[0006] The cleaning device provided by the present disclosure includes a body and a dust cup for collecting dust. The body is provided with an inlet, an outlet, a traveling mechanism, a platform, a locking mechanism and a lifting mechanism, and the body moves on the ground through the traveling mechanism. The dust cup is placed on the platform. The locking mechanism is configured to releasably fix the dust cup to the body. The lifting mechanism is configured to lift the dust cup after the dust cup is released so that the dust cup can be released from the position locked by the locking mechanism. The direction of the dust cup facing away from the inlet is defined as rear, and the direction of the dust cup facing the cleaning surface is defined as downward. The locking mechanism is located behind the dust cup. The lifting mechanism is located below the dust cup and further back than the center of gravity of the dust cup, or the lifting mechanism is located behind the dust cup so as to lift the dust cup forward in an inclined manner after the dust cup is released.

[0007] The user can operate the locking mechanism to release the dust cup. As the dust cup is released by the locking mechanism, the dust cup is tilted forward by the lifting mechanism to escape from the position locked by the locking mechanism. Even if the user releases the locking mechanism, the dust cup will not be locked again. In this way, the user will be able to release and remove the dust cup with one hand, which is more convenient to operate. In addition, this implementation does not rely on a locking mechanism and a lifting mechanism with complex structures, and the structure is relatively simple.

[0008] As a possible implementation, the locking mechanism includes a locking piece and a first elastic piece. The dust cup is provided with a locking recess. The first elastic piece is configured to apply an elastic force to the locking piece to keep the locking piece in a locking position partially extending into the locking recess. The locking piece can overcome the elastic force under operation and move to a release position disengaged from the locking recess.

[0009] The user only needs to move the locking member in a direction away from the locking recess to move the locking member from the locking position to the releasing position to release the dust cup. After the user releases the locking member, the locking member will be reset to the locking position under the action of the first elastic member, so that after the dust cup is in place again, the locking member can automatically lock the dust cup again. This implementation method has many advantages such as simple structure and convenient operation.

[0010] As a possible implementation, the body is further provided with a handle for the user to hold, the locking member and the first elastic member are installed in the handle, the locking member is provided with an operating portion for receiving an operation, and the handle is provided with a window exposing the operating portion.

[0011] This implementation makes full use of the space in the handle, which can help the cleaning device obtain a relatively compact structure. In addition, the structure in which the locking element is accommodated in the handle can help the user to operate the locking element more conveniently.

[0012] As a possible implementation, the dust cup is provided with a first guide structure, and the body is provided with a second guide structure. In the process of placing the dust cup on the platform, as the first guide structure is combined with the second guide structure, the dust cup is guided to a position where the locking recess is aligned with the locking member, so as to allow the locking member to partially extend into the locking recess.

[0013] By means of the first guide structure and the second guide structure, the locking member and the locking recess can be aligned more easily during the process of placing the dust cup on the platform.

[0014] As a possible implementation method, the body is also provided with a handle for the user to hold, the locking mechanism is arranged in the handle, the front end face of the handle is provided with a through hole for partially extending the locking piece, the dust cup is provided with a coupling portion coupled to the front end of the handle, the coupling portion is provided with a rear end face, the locking recess is recessed forward from the rear end face, the first guide structure is located above the locking recess and protrudes rearward beyond the rear end face, the first guide structure comprises an upwardly recessed first guide recess and a downwardly protruding first guide protrusion in sequence backward, the second guide structure is provided at the front end of the handle and is located above the through hole, the second guide structure comprises a downwardly recessed second guide recess and an upwardly protruding second guide protrusion in sequence forward, the first guide protrusion and the second guide protrusion extend into the first guide recess and the second guide recess respectively to combine the first guide structure with the second guide structure.

[0015] In the process of placing the dust cup on the platform, the first guide protrusion gradually extends into the first guide recess, and the second guide protrusion gradually extends into the second guide recess. Under the cooperation of the first guide protrusion and the second guide recess, and under the cooperation of the second guide protrusion and the first guide recess, the dust cup will be accurately positioned relative to the body, thereby making it easier to align the locking piece and the locking recess.

[0016] As a possible implementation, the lifting mechanism includes a top cap and a second elastic member, wherein the top cap is mounted on the top end of the second elastic member, so that when the dust cup is placed on the platform, the dust cup compresses the second elastic member through the top cap.

[0017] In this implementation, when the dust cup is locked by the locking mechanism, the second elastic member is compressed, and when the dust cup is released, the elastic restoring force of the second elastic member lifts the dust cup. This implementation has many advantages such as simple structure and convenient assembly and disassembly.

[0018] As a possible implementation manner, a receiving recess is provided at the bottom of the dust cup, and the receiving recess is configured to receive at least a portion of the top cap.

[0019] In the process of placing the dust cup on the platform, the cooperation of the top cap and the receiving recess can help the dust cup to be accurately in place. After the dust cup is locked, the cooperation of the top cap and the receiving recess can help the dust cup to be reliably fixed.

[0020] As a possible implementation manner, the receiving recess is configured to gradually expand outwards as it goes downwards.

[0021] According to such a configuration of the receiving recess, the top cap and the receiving recess can be relatively easily aligned during the process of placing the dust cup on the platform.

[0022] As a possible implementation, the lifting mechanism includes a pair of magnetic members, which are respectively fixed to the dust cup and the body. When the dust cup is placed on the platform, the pair of magnetic members have the same poles facing each other.

[0023] In this implementation, when the dust cup is locked by the locking mechanism, a pair of magnetic parts accumulate magnetic potential energy, and when the dust cup is released, the magnetic repulsion between the pair of magnetic parts lifts the dust cup. This implementation has many advantages such as simple structure and easy assembly and disassembly.

[0024] As a possible implementation manner, the fuselage is further provided with an enclosure portion, which protrudes upward from the platform and surrounds the platform.

[0025] The enclosure has a limiting function. When the dust cup is locked by the locking mechanism, the enclosure can help the dust cup to be more reliably fixed to the machine body. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is an exemplary description of the embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the present disclosure can be implemented in a variety of ways and should not be construed as being limited to the embodiments described herein, which are only for a more thorough and clear understanding of the present disclosure.

[0037] refer to Figure 1 and Figure 2 The present disclosure provides a cleaning device 100. For example, the cleaning device 100 provided by the present disclosure may be a horizontal vacuum cleaner. Figure 1 As shown, the cleaning device 100 may include a body 10, and the body 10 may be provided with a running mechanism 11, and the body 10 may move on the ground through the running mechanism 11, thereby driving the cleaning device 100 to move and clean on the ground. For example, the running mechanism 11 may be a running wheel 11.

[0038] refer to Figures 1 to 3 The cleaning device 100 may further include a dust cup 20, and the body 10 may further be provided with an inlet 10a, an outlet (not shown in the figure), a platform 12 and a suction source (not shown in the figure), and the dust cup 20 may be placed on the platform 12. During operation, the cleaning device 100 may generate negative pressure through the suction source, suck in air and dust through the inlet 10a by suction, and then collect the dust in the dust cup 20, and discharge the air through the outlet to achieve the cleaning purpose. For example, the suction source may be a fan. After a lot of dust accumulates in the dust cup 20, the user may remove the dust cup 20 from the body 10, and then empty the dust in the dust cup 20.

[0039] Combination FIG. 4A to FIG. 5B The body 10 may also be provided with a locking mechanism 13 and a lifting mechanism 14. The locking mechanism 13 may be configured to releasably fix the dust cup 20 to the body 11. The lifting mechanism 14 may be configured to lift the dust cup 20 after the dust cup 20 is released, so that the dust cup 20 can be released from the position locked by the locking mechanism 13, that is, the dust cup 20 is released from the position locked by the locking mechanism 13. Figure 4A and Figure 5A The locked position is lifted to Figure 4B and Figure 5B The position in which it cannot be locked.

[0040] Specifically, the locking mechanism 13 is located behind the dust cup 20, and the lifting mechanism 14 is located below the dust cup 20 and higher than the center of gravity O of the dust cup 20 (at Figure 5A and Figure 5B ) further back, so that the dust cup 20 is tilted forward and lifted up after the dust cup 20 is released, as shown in FIG. FIG. 5A to FIG. 5B It should be noted that, in the present disclosure, the direction of the dust cup 20 facing away from the inlet 10a is defined as the rear, and the direction of the dust cup 20 facing the cleaning surface is defined as the downward direction.

[0041] According to the cleaning device 100 provided in the present disclosure, the user can release the dust cup 20 by operating the locking mechanism 13. As the dust cup 20 is released by the locking mechanism 13, the dust cup 20 is tilted forward by the lifting mechanism 14 to escape from the position locked by the locking mechanism 13. Even if the user releases the locking mechanism 13, the dust cup 20 will not be locked again. In this way, the user will be able to release and remove the dust cup 20 with one hand, which is more convenient to operate. In addition, this implementation method does not rely on the locking mechanism 13 and the lifting mechanism 14 with complex structures, and the structure is relatively simple.

[0042] There are many ways to implement the locking mechanism 13, which is not particularly limited in the present disclosure. Figure 4A and Figure 4B The locking mechanism 13 may include a locking member 131 and a first elastic member 132, and the dust cup 20 may be provided with a locking recess 21. Figure 4A As shown, the first elastic member 132 may be configured to apply elastic force to the locking member 131 to keep the locking member 131 in a locked position partially extending into the locking recess 21. Figure 4B The locking member 131 can overcome the elastic force of the first elastic member 132 (for example, by moving backward) under operation and move to a release position disengaged from the locking recess 21 .

[0043] In this implementation, the user only needs to move the locking member 131 in a direction away from the locking recess 21 to move the locking member 131 from Figure 4A Move the lock position in Figure 4B After the user releases the locking member 131, the locking member 131 will be reset to the release position under the action of the first elastic member 132. Figure 4A The locking position in the middle makes the dust cup 20 automatically lock the dust cup 20 again after the dust cup 20 is in place again. This implementation has many advantages such as simple structure and convenient operation.

[0044] As a non-limiting example, the front end of the locking member 131 can be configured as a locking tongue suitable for extending into the locking recess 21, the first elastic member 132 can be a compression spring, and the rear end of the locking member 131 can be configured as a cylinder for the first elastic member 132 to be sleeved. Of course, the specific form of the locking member 131 is not limited to the above, for example, the front end of the locking member 131 and the locking recess 21 can also be configured as a buckle form.

[0045] Continue to refer Figures 1 to 4BThe body 10 may also be provided with a handle 15 for the user to hold, and the locking member 131 and the first elastic member 132 may be installed in the handle 15. The locking member 131 may be provided with an operating portion 1311 for receiving an operation, and the handle 15 may be provided with a window 151, and the operating portion 1311 is exposed to the outside through the window 151 to facilitate the user's operation. This implementation method makes full use of the space in the handle 15, which can help the cleaning device 100 obtain a relatively compact structure. In addition, the structure in which the locking member 131 is accommodated in the handle 15 can help the user to operate the locking member 15 more conveniently.

[0046] refer to Figure 4A and Figure 4B The dust cup 20 may be provided with a first guide structure 22, and the fuselage 10 may be provided with a second guide structure 16. In the process of placing the dust cup 20 on the platform 12, refer to Figure 4B and Figure 4A As the first guide structure 22 is combined with the second guide structure 16, the dust cup 20 is guided to a position where the locking recess 21 is aligned with the locking member 131, allowing the locking member 131 to partially extend into the locking recess 21. Through the first guide structure 22 and the second guide structure 16, the locking member 131 and the locking recess 21 are more easily aligned during the process of placing the dust cup 20 on the platform 12.

[0047] There are many ways to implement the first guide structure 22 and the second guide structure 16, which are not particularly limited in the present disclosure. Figure 4A and Figure 4B The front end surface 152 of the handle 15 may be provided with a through hole 153 for the locking member 131 to partially extend. Figure 1 The dust cup 20 may be provided with a coupling portion 23 coupled to the front end of the handle 15. Figure 4A and Figure 4B , the coupling portion 23 may be provided with a rear end face 24, and the locking recess 21 is recessed forward from the rear end face 24. The first guide structure 22 is located above the locking recess 21 and protrudes backward beyond the rear end face 24. The first guide structure 22 includes an upwardly recessed first guide recess 221 and a downwardly protruding first guide protrusion 222 in sequence. The second guide structure 16 is provided at the front end of the handle 15 and located above the through opening 153. The second guide structure 16 includes a downwardly recessed second guide recess 161 and an upwardly protruding second guide protrusion 162 in sequence. The first guide protrusion 222 and the second guide protrusion 162 extend into the first guide recess 221 and the second guide recess 161 respectively to combine the first guide structure 22 with the second guide structure 16.

[0048] According to this implementation, in the process of placing the dust cup 20 on the platform 12, the first guide protrusion 222 gradually extends into the first guide recess 221, and the second guide protrusion 162 gradually extends into the second guide recess 161. Under the cooperation between the first guide protrusion 222 and the second guide recess 161, and under the cooperation between the second guide protrusion 162 and the first guide recess 221, the dust cup 20 will be accurately positioned relative to the fuselage 10, thereby making it easier to align the locking piece 131 and the locking recess 21.

[0049] There are many ways to implement the lifting mechanism 14, and the present disclosure does not impose any particular restrictions on this. As an implementation method, refer to Figure 5A and Figure 5B The lifting mechanism 14 may include a top cap 141 and a second elastic member 142, and the top cap 141 is mounted on the top of the second elastic member 142. When the dust cup 20 is locked by the locking mechanism 13, the second elastic member 142 is compressed, and when the dust cup 20 is released, the elastic restoring force of the second elastic member 142 lifts the dust cup 20. This implementation has many advantages such as simple structure and convenient assembly and disassembly.

[0050] Continue to refer Figure 5A and Figure 5B The bottom of the dust cup 20 may be provided with a receiving recess 25, which may be configured to receive at least a portion of the top cap 141. In the process of placing the dust cup 20 on the platform 12, the cooperation between the top cap 141 and the receiving recess 25 can help the dust cup 20 to be accurately positioned. After the dust cup 20 is locked, the cooperation between the top cap 141 and the receiving recess 25 can help the dust cup 20 to be reliably fixed.

[0051] Continue to refer Figure 5A and Figure 5B The receiving recess 25 can be configured to expand gradually as it moves downward. According to this configuration of the receiving recess 25, when the dust cup 20 is placed on the platform 12, the top cap 141 and the receiving recess 25 can be aligned relatively easily.

[0052] refer to Figure 1 , Figure 3 , Figure 5A and Figure 5B The fuselage 10 may also be provided with a blocking portion 17, which may protrude upward from the platform 12 and surround the platform 12. The blocking portion 17 has a limiting function. Therefore, when the dust cup 20 is locked by the locking mechanism 13, the blocking portion 17 can help the dust cup 20 to be more reliably fixed to the fuselage 10.

[0053] For ease of understanding, the process of locking and releasing the dust cup 20 is described below by way of example.

[0054] When the dust cup 20 is locked, Figure 4AAs shown, the front end of the locking member 131 extends into the locking recess 21 to lock the dust cup 20 and fix the dust cup 20 to the body 10. At this time, under the cooperation of the locking member 131 and the locking recess 21, the dust cup 20 overcomes the force of the lifting mechanism 14. As the locking member 131 moves backward under the operation of the user, the front end of the locking member 131 withdraws from the locking recess 21, and the first elastic member 132 is compressed. After the locking member 131 completely withdraws from the locking recess 21, the dust cup 20 is released, so that under the action of the lifting mechanism 14, the dust cup 20 is lifted up at an angle forward. The dust cup 20 is Figure 4A and Figure 5A In the state, switch to Figure 4B and Figure 5B At this time, the user can release the locking member 131, and since the dust cup 20 has been lifted up, the dust cup 20 will not be locked again. Then, the user can take away the dust cup 20 to empty the dust in the dust cup.

[0055] After the dust cup 20 is cleaned, the user can place the dust cup 20 on the platform 12 again. Figure 4B and Figure 5B Then, the user can press down the rear of the dust cup 20, so that the dust cup 20 overcomes the force from the lifting mechanism 14 and moves to the position where the front end of the locking member 131 is aligned with the locking recess 21. In this process, the first guide protrusion 222 and the second guide protrusion 162 extend into the first guide recess 221 and the second guide recess 161 respectively to guide the dust cup 20 to be accurately positioned. After the front end of the locking member 131 is aligned with the locking recess 21, as shown in FIG. Figure 4A and Figure 5A As shown, under the action of the first elastic member 132 , the front end of the locking member 131 will automatically extend into the locking recess 21 to achieve re-locking of the dust cup 20 .

[0056] The above is an example of a cleaning device 100 according to an embodiment of the present disclosure. It is understood that the cleaning device according to the present disclosure is not limited to the above. 6A to 7B , some modified examples of the cleaning devices according to the present disclosure are given as examples. It should be noted that the cleaning devices according to the modified examples of the present disclosure described below are substantially the same as the cleaning device 100 described above, and they have many identical or similar elements. For the purpose of brevity, identical or similar elements will be denoted by the same reference numerals in this document to appropriately omit repeated descriptions.

[0057] refer to Fig. 6A and Figure 6BIn a modified example of the present disclosure, the lifting mechanism 14a can be located behind the dust cup 20, and can lift the dust cup forward and upward. The lifting mechanism 14a of this structure can also achieve the function mentioned above, that is, after the dust cup 20 is released, the lifting mechanism 14a can lift the dust cup 20 forward and upward.

[0058] refer to Fig. 7A and Figure 7B In another variation of the present disclosure, the lifting mechanism 14b may include a first magnetic member 141b and a second magnetic member 142b, wherein the first magnetic member 141b is fixed to the bottom of the dust cup 20, and the second magnetic member 142b is fixed to the fuselage platform 12. When the dust cup 20 is placed on the platform 22, the two magnetic members 141b and 142b have the same poles facing each other.

[0059] In this implementation, when the dust cup 20 is locked by the locking mechanism 13, the two magnetic parts 141b and 142b accumulate magnetic potential energy; when the dust cup 20 is released, the magnetic repulsion between the two magnetic parts 141b and 142b lifts the dust cup 20. This implementation has many advantages such as simple structure and easy assembly and disassembly.

[0060] It is understood that in the present disclosure, directional descriptions such as "upper", "lower", "front", "back", etc. are relative rather than absolute. When the cleaning device provided by the present disclosure is placed in the posture and position shown in the accompanying drawings, these directional words may be applicable.

[0061] It should be understood that although the terms "first" or "second" etc. may be used in the present disclosure to describe various elements (such as a first elastic member and a second elastic member), these elements are not defined by these terms, which are merely used to distinguish one element from another.

[0062] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
