Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust collectors, in particular to a safety switch protection structure and a table dust collector with the same. BACKGROUND

[0002] A table dust collector is a small and handy dust removal device that can be held by one hand. Its working principle is that a motor inside the table dust collector drives an impeller to work, the impeller generates an airflow from bottom to top, the airflow wraps up the debris on the working surface and enters the dust collection cavity, the filter screen in the dust collection cavity traps the debris to achieve the purpose of dust collection. When removing the filter screen to clean the debris, if the start switch is accidentally touched, the rotating impeller will cause harm to the user. In order to avoid this situation, the following two schemes are generally used:

[0003] One scheme is disclosed in the Chinese Utility Model Patent with the authorized announcement number CN212281187U, which discloses a dust collector and a dust collector with the same. The dust collector is provided with a limiting component suitable for limiting the rotation of the impeller. This structure is simple, but there is a problem that the limiting component and the outer circle of the impeller are impacted to cause damage to the impeller.

[0004] Another scheme is disclosed in the Chinese Utility Model Patent with the authorized announcement number CN213488591U, which discloses a handheld dust collector. The handheld dust collector is provided with a first switch. When the bottom cover and the upper cover are separated, the first switch is used to control the suction assembly to stop working. This scheme realizes safety protection through the on-off control of the circuit, and has strong reliability. It is a commonly used technology at present. There is a three-section table dust collector. The space formed by the upper cover and the intermediate assembly cover is used to install a detachable battery, and the space formed by the bottom cover and the intermediate assembly is a dust collection cavity. Based on this scheme, two series safety switches are generally arranged on the intermediate assembly. The triggering mechanism of one safety switch is the connection or disconnection of the upper cover and the intermediate assembly, and the triggering mechanism of the other safety switch is the connection or disconnection of the bottom cover and the intermediate assembly. The two safety switch schemes have high cost. How to further improve the scheme is a technical problem that needs to be solved by related technical personnel. SUMMARY

[0005] The present application aims to at least solve one of the technical problems in the related art. To this end, the present application provides a safety switch protection structure, which uses a single safety switch as a protection element of the upper cover and the bottom cover by arranging a touch piece, thereby replacing the double safety switch scheme in the prior art and reducing the cost.

[0006] The present application also provides a table dust collector with the safety switch protection structure.

[0007] The technical scheme adopted by the present application is to provide a safety switch protection structure, which comprises:

[0008] an upper cover;

[0009] an intermediate assembly connected with the upper cover to form a space suitable for installing a battery;

[0010] a bottom cover connected with the intermediate assembly to form a dust suction cavity;

[0011] The intermediate assembly is provided with a trigger and a safety switch for controlling the on-off of the motor. When the upper cover and the bottom cover are both connected with the intermediate assembly, the trigger triggers the safety switch, so that the safety switch controls the motor to be in an openable state. When at least one of the upper cover and the bottom cover is disconnected from the intermediate assembly, the trigger is disconnected from the safety switch, so that the safety switch controls the motor to be in a closed state.

[0012] After the above structure is adopted, the safety switch can be used as a protection element of the upper cover and the bottom cover. That is, when the upper cover is removed for replacing the battery, the motor stops working. When the bottom cover is removed for opening the dust suction cavity, the motor stops working, thereby playing a protection role of the desktop dust collector. In the prior art, the two safety switches are connected in series, and the failure rate is the superposition of the failure rates of the single safety switches. Compared with the double-safety-switch scheme, the single-safety-switch scheme can reduce the cost and the failure rate of the desktop dust collector.

[0013] According to an embodiment of the present application, the two ends of the trigger are respectively connected with a first trigger end and a second trigger end. The first trigger end swings between a first position and a second position relative to the intermediate assembly. The second trigger end swings between a third position and a fourth position relative to the intermediate assembly.

[0014] According to an embodiment of the present application, when the first trigger end is located at the second position and the second trigger end is located at the fourth position, the trigger triggers the safety switch, so that the safety switch controls the motor to be in an openable state, that is, the desktop dust collector can be normally used.

[0015] According to an embodiment of the present application, the upper cover is provided with a first abutting protrusion. When the upper cover is connected with the intermediate assembly, the first abutting protrusion abuts against the first trigger end, so that the first trigger end is kept at the second position. When the upper cover is positioned and connected with the intermediate assembly, the first abutting protrusion rotates to a predetermined position and abuts against the trigger.

[0016] According to an embodiment of the present application, the first trigger end is provided with a second positioning protrusion. The width of the second positioning protrusion in the width direction of the first trigger end is smaller than the width of the first trigger end. The width of the first abutting protrusion is not greater than the width of the second positioning protrusion. When the first abutting protrusion abuts against the second positioning protrusion, the first trigger end is located at the second position.

[0017] According to one embodiment of the present invention, the bottom cover has a second abutting protrusion, which abuts against the second trigger end when the bottom cover is connected to the intermediate component, thereby holding the second trigger end in a fourth position.

[0018] According to one embodiment of the present invention, the intermediate component is provided with a first limiting protrusion and a second limiting protrusion spaced apart, and the first trigger end swings between the first limiting protrusion and the second limiting protrusion.

[0019] According to one embodiment of the present invention, the first trigger end located at the first position abuts against the second limiting protrusion.

[0020] According to one embodiment of the present invention, an elastic element is provided between the trigger and the safety switch, the elastic element having an elastic tendency to limit the trigger to activate the safety switch.

[0021] A desktop vacuum cleaner includes a safety switch protection structure as described above. Attached Figure Description

[0050] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which the same or similar elements have the same or similar reference numbers. The embodiments described below are examples only, and are not to be construed as limiting the present application.

[0051] In the present embodiment, the openable and closable state of the motor 7 specifically refers to the circuit of the motor 7 being connected, and the start switch 6 directly controlling the start and stop of the motor 7. The closed state of the motor 7 specifically refers to the circuit of the motor 7 being disconnected, and the motor 7 in the working state being directly stopped, and the start switch 6 being unable to directly control the start and stop of the motor 7.

[0052] As shown in the drawings, a safety switch 9 protection structure is disclosed in the present embodiment, which comprises: Figures 1 to 6

[0053] the upper cover 1;

[0054] the intermediate assembly, which is connected with the upper cover 1 to form a space suitable for installing a battery;

[0055] the bottom cover 3, which is connected with the intermediate assembly to form a dust suction cavity;

[0056] The intermediate assembly is provided with a trigger 8 and a safety switch 9 for controlling the start and stop of the motor 7. When the upper cover 1 and the bottom cover 3 are both connected with the intermediate assembly, the trigger 8 triggers the safety switch 9, so that the safety switch 9 controls the motor 7 to be in an openable state. When at least one of the upper cover 1 and the bottom cover 3 is disconnected from the intermediate assembly, the trigger 8 is disconnected from the safety switch 9, so that the safety switch 9 controls the motor 7 to be in a closed state.

[0057] Specifically, in combination with Figures 2 to 4 ​As shown, in the embodiment, the intermediate assembly includes the bracket 2 and the middle cover 4, the bottom of the bracket 2 is rotatably connected with the bottom cover 3 to form a dust suction cavity, and the middle cover 4 is fixedly connected with the bracket 2. The motor 7 is fixedly installed in the space formed by the bracket 2 and the middle cover 4, the motor shaft extends to the bottom of the bracket 2 and is connected with the impeller. The impeller is located in the dust suction cavity, the filter screen is detachably connected with the bottom of the bracket 2, and the filter screen is arranged around the circumference of the impeller. The upper cover 1 is rotatably connected with the middle cover 4, and the battery compartment for installing the battery is formed at the upper end of the middle cover 4.

[0058] Specifically, in combination with Figure 19 As shown, the side of the actuator 8 towards the safety switch 9 extends to form a trigger protrusion 83, and the trigger protrusion 83 is arranged corresponding to the switch position on the push-button safety switch 9. That is, when the trigger protrusion 83 abuts against the switch position, the safety switch 9 is opened, and when the trigger protrusion 83 is disconnected from the switch position, the safety switch 9 is disconnected.

[0059] Specifically, in combination with Figure 16 As shown, the upper cover 1 and the middle cover 4 are disconnected in the figure, the bottom cover 3 and the bracket 2 are disconnected, the first trigger end 81 is located at the first safety position, the second trigger end 82 is located at the third safety position, and the trigger protrusion 83 has a gap with the safety switch 9.

[0060] Further, the two ends of the actuator 8 are respectively connected with the first trigger end 81 and the second trigger end 82, the first trigger end 81 swings between the first position and the second position relative to the intermediate assembly, and the second trigger end 82 swings between the third position and the fourth position relative to the intermediate assembly.

[0061] Specifically, in combination with Figure 17 As shown, the upper cover 1 and the middle cover 4 are disconnected in the figure, the bottom cover 3 and the bracket 2 are connected, the second trigger end 82 moves towards the safety switch 9, and the first trigger end 81 moves away from the safety switch 9. The first trigger end 81 is located at the first position, and the second trigger end 82 is located at the fourth position.

[0062] Further, in combination with Figures 13 to 15 As shown, the bottom cover 3 has a second abutting protrusion 31, when the bottom cover 3 is connected with the intermediate assembly, the second abutting protrusion 31 abuts against the second trigger end 82, so that the second trigger end 82 is kept at the fourth position.

[0063] Specifically, the inner wall of the bottom cover 3 is rotationally connected with the outer wall of the bottom end of the support 2, and the second abutting protrusion 31 is arranged in a spaced manner with the inner wall of the bottom cover 3. An annular groove adapted to the second abutting protrusion 31 is arranged on the bottom surface of the support 2. The second abutting protrusion 31 is located on one side of the annular groove, and the first positioning protrusion 24 is arranged on the other side of the annular groove. When the bottom cover 3 is positioned and connected with the support 2, the second abutting protrusion 31 abuts against the first positioning protrusion 24, so that the bottom cover 3 is closely connected with the support 2, and a paragraph sense is formed to prompt the user that the bottom cover 3 is connected with the support 2 to a predetermined position. At this time, the second abutting protrusion 31 abuts against the second trigger end 82, so that the second trigger end 82 moves from the third position to the fourth position.

[0064] Further, when the first trigger end 81 is located at the second position and the second trigger end 82 is located at the fourth position, the trigger member 8 triggers the safety switch 9, so that the safety switch 9 controls the motor 7 to be in an openable state, that is, the table surface cleaner can be normally used.

[0065] Specifically, as shown in Figure 18 , the first trigger end 81 in the figure is located at the second position, the second trigger end 82 is located at the fourth position, and the trigger protrusion 83 abuts against the switch position on the safety switch 9.

[0066] Further, as shown in Figures 6 to 7 and Figure 12 , the upper cover 1 has a first abutting protrusion 11. When the upper cover 1 is connected with the middle assembly, the first abutting protrusion 11 abuts against the first trigger end 81, so that the first trigger end 81 is kept at the second position.

[0067] Specifically, the first trigger end 81 on the trigger member 8 extends upward from the support 2, and the protection portion 41 corresponding to the first trigger end 81 is arranged on the middle cover 4. The first trigger end 81 is located in the protection portion 41 and can move between the first position and the second position. One side of the protection portion 41 is provided with an opening, and the first trigger end 81 extends out of the opening.

[0068] Further, the inner wall of the upper cover 1 is rotationally connected with the outer wall of the middle cover 4, and the first abutting protrusion 11 is arranged in a spaced manner with the inner wall of the upper cover 1. The protection portion 41 and the inner wall of the middle cover 4 form a matching gap 42, and the opening on the protection portion 41 is located on one side of the matching gap 42. When the upper cover 1 is positioned and connected with the middle cover 4, the first abutting protrusion 11 abuts against the first trigger end 81, so that the first trigger end 81 moves from a side away from the safety switch 9 to a side close to the safety switch 9, that is, the first trigger end 81 moves from the first position to the second position.

[0069] Further, as shown in Figures 8 to 11As shown, the first trigger end 81 is provided with a second positioning protrusion 81a, the width of the second positioning protrusion 81a along the width direction of the first trigger end 81 is less than the width of the first trigger end 81, the width of the first abutting protrusion 11 is not greater than the width of the second positioning protrusion 81a, when the first abutting protrusion 11 abuts against the second positioning protrusion 81a, the first trigger end 81 is located at the second position.

[0070] Specifically, when the upper cover 1 is positioned and connected with the middle cover 4, the second positioning protrusion 81a abuts against the first trigger end 81, so that the upper cover 1 is connected closely with the middle cover 4.

[0071] Further, the intermediate assembly is provided with a first limiting protrusion 22 and a second limiting protrusion 23 at intervals, and the first trigger end 81 swings between the first limiting protrusion 22 and the second limiting protrusion 23.

[0072] Specifically, in combination with Figure 8 and Figure 9 As shown, in the embodiment, the upper end of the support 2 extends upward to form two support portions 21, the two support portions 21 are arranged at intervals and in parallel, and the first limiting protrusion 22 and the second limiting protrusion 23 are respectively located on both sides of the upper end of each support portion 21. The end surface of the support portion 21 between the first limiting protrusion 22 and the second limiting protrusion 23 is arc-shaped. The first trigger end 81 extends to both sides along the width direction to form an extension shaft structure, and the extension shaft structure moves between the first limiting protrusion 22 and the second limiting protrusion 23.

[0073] Further, in combination with Figure 10 and Figure 11 As shown, the first trigger end 81 at the first position abuts against the second limiting protrusion 23.

[0074] Specifically, the extension shaft structure on the first trigger end 81 is provided with a contact inclined surface 81b, which is used to abut against the second limiting protrusion 23.

[0075] Further, in combination with Figures 16 to 18 As shown, the elastic member 10 is arranged between the trigger 8 and the safety switch 9, and the elastic member 10 has an elastic tendency to limit the triggering of the safety switch 9 by the trigger 8.

[0076] Further, in the embodiment, one end of the elastic member 10 abuts against the safety switch 9, and the other end is sleeved on the outer periphery of the trigger protrusion 83.

[0077] In combination with Figures 1 to 4 As shown, in another embodiment, a table vacuum cleaner is disclosed, which comprises the safety switch 9 protection structure in the embodiment.

[0078] Specifically, in another embodiment, the top end of the upper cover 1 is provided with a switch button 5, and the middle cover 4 is provided with a starting switch 6, and the switch button 5 abuts against the starting switch 6. Pressing the switch button 5 triggers the starting switch 6, and the starting switch 6 is in series with a safety switch 9.

[0079] In another embodiment, the working principle of the table dust collector is as follows:

[0080] When the upper cover 1 is connected with the middle cover 4, and the bottom cover 3 is connected with the support 2, the actuator 8 triggers the safety switch 9, so that the safety switch 9 controls the motor 7 to be in an openable state. Pressing the starting switch 6 drives the motor 7 to work and drive the impeller to rotate. The impeller generates an upward air flow, and the air flow wraps the sundries on the working surface and enters the dust collection cavity. The filter screen in the dust collection cavity traps the sundries. Pressing the starting switch 6 again stops the motor 7 from working. At this time, when the upper cover 1 is relatively rotated with the middle cover 4, and / or the bottom cover 3 is relatively rotated with the support 2, the actuator 8 is disconnected with the safety switch 9, so that the safety switch 9 controls the motor 7 to be in a closed state, and the motor 7 stops working.
