[0034] The utility model provides a door opening device, which is used for controlling the door opening of a cleaning tool base station.

[0035] Combination Figure 1 and Figure 2 As shown, in one embodiment of the utility model, the door opening device includes a box body, a driving member, a pushing part and a micro switch; an installation space is formed inside the box body, and an opening connected to the installation space is opened at one end; the driving member is arranged in the installation space; the pushing part is movably arranged in the installation space, and one end is drivingly connected to the driving member, and the other end of the pushing part is drivingly connected to the door panel of the cleaning tool base station, and the driving member drives the pushing part to extend out of the opening to drive the door panel to open the entrance of the cleaning tool; the micro switch is arranged on the outside of the box body, and the micro switch is communicatively connected to the driving member. When the entrance of the cleaning tool is fully opened, the pushing part moves to abut against the micro switch, and the micro switch controls the driving member to stop working.

[0036] In this embodiment, the door opening device is applied to the door opening structure of the intelligent cleaning appliance base station, and the intelligent cleaning appliance may be a vacuum cleaner, a floor scrubber, or other appliances. The box in the door opening device is mainly used to install and protect the various components of the door opening device. The installation space can be designed to include different chambers according to the shape and position of the driving part, the pushing part, and other components, so as to fix and install the various components respectively, thereby improving the stability of the door opening device during operation.

[0037] The driving part can be a brushed DC motor, a brushless DC motor, an AC motor, etc., to achieve a quick response to the base station door opening signal and drive the push part to move. The output shaft of the motor is directly connected to the push part, or it can be connected through a transmission component.

[0038] The push part is movably arranged in the installation space, and can be connected to the installation space by sliding or rolling. The push part is arranged toward the opening in the moving direction of the installation space, so that one end of the push part can be extended to the outside of the box body under the drive of the driving member, and drive the door panel of the cleaning tool base station to open.

[0039] The micro switch can be a contact switch, and the driving member can be controlled to be closed by pressing the micro switch by the movement of the pusher. The communication connection mode between the micro switch and the driving member can be wired or wireless.

[0040] When the cleaning tool has finished cleaning and needs to enter the base station, the sensor of the base station triggers and starts the driving member, driving the push part to move and open the door. When the push part touches the micro switch, the driving member stops driving and completes the door opening action; in addition, when the push part is reset, the micro switch is also used to control the start and stop of the driving member. This application improves the accuracy of the door opening device controlling the door opening of the cleaning tool base station by using a micro switch to control the movement of the push part, thereby improving the user experience.

[0041] Combination Figure 1 and Figure 5 As shown, in one embodiment of the utility model, a slot communicating with the installation space is provided on the surface of the box body, the slot is extended along the moving direction of the pushing part, a plug plate is provided on one side of the pushing part, and a side of the plug plate away from the pushing part is movably inserted into the slot and extends to the outside of the box body;

[0042] The micro switch is located at one end of the slot, and the driving member drives the pushing part to drive the plug plate to move. When the entrance of the cleaning tool is fully opened, the plug plate abuts against the micro switch.

[0043] In this embodiment, the slot is adapted to the shape of the plug board, one end of the plug board passes through the slot, the slot wall forms a limit for the plug board, and the slot is extended along the direction of movement of the push part, and then the slot guides the plug board, improving the accuracy of the push part driving the door to open. The micro switch is arranged on the outside of the box, which improves the convenience of assembly and replacement of the micro switch.

[0044] The micro switch is designed to be detachably connected to the outer surface of the box and is located at one end of the slot. Therefore, by controlling the installation position of the micro switch or the moving distance of the plug plate, it is more convenient to achieve precise control of the length of the push part extending out of the opening, thereby improving the accuracy of the door opening device in controlling the door opening.

[0045] Combination Figure 1 and Figure 5 As shown, in one embodiment of the present utility model, a fixing groove is provided on the surface of the box body, and the micro switch is arranged in the fixing groove.

[0046] In this embodiment, the fixing groove has a circumferential limiting effect on the micro switch, thereby improving the stability of the micro switch. A notch is provided on the groove wall of the fixing groove on the side facing the slot, so that the micro switch is exposed on the side facing the slot, thereby facilitating contact with the plug board. A notch is also provided on the side of the fixing groove away from the slot, which facilitates the communication connection end of the micro switch to extend out of the fixing groove and communicate with the drive member.

[0047] The fixing groove can be formed by a plurality of enclosures arranged on the surface of the box body, or can be formed by a depression on the surface of the box body. As long as the above-mentioned effects can be achieved, they belong to the protection scope of this application.

[0048] Combination Figure 1 and Figure 5 As shown, in one embodiment of the utility model, a positioning pin is protruding from the bottom of the fixing groove, a positioning hole is formed in the micro switch, and the positioning pin is inserted into the positioning hole.

[0049] In this embodiment, the positioning pin at the bottom of the fixing groove cooperates with the positioning hole of the micro switch to further limit the micro switch and improve the stability of the micro switch. Through the cooperation of the positioning pin and the positioning hole, the micro switch can be quickly positioned and installed in the fixing groove, thereby improving the installation efficiency.

[0050] Combination Figure 1 and Figure 5 As shown, in one embodiment of the utility model, two locating pins are provided at the bottom of the fixing slot, and the micro switch is provided with two locating holes. At least one side of the locating pin is flat and matched with the locating hole to prevent the micro switch from being assembled fool-proof.

[0051] In this embodiment, two positioning pins are arranged at the bottom of the fixing groove, so that after the micro switch is fixed in the fixing groove, the two positioning pins jointly limit the micro switch, further improving the stability of the micro switch. At the same time, one side of one of the positioning pins is arranged on a plane, and the side wall of one side of the positioning hole matched with it is designed to be flat, so as to limit the direction in which the positioning pin is inserted into the positioning hole, thereby playing a fool-proof effect when the micro switch is assembled in the fixing groove, and preventing the micro switch from being installed upside down.

[0052] Combination Figure 1 and Figure 5 As shown, in one embodiment of the utility model, a slot wall on one side of the fixing slot is provided with a hook, the micro switch is embedded in the fixing slot, and the hook is engaged with the micro switch.

[0053] In this embodiment, the micro switch is in contact with the wall of the fixing groove, and the hook is located at a position of the wall of the fixing groove away from the bottom of the groove. Figure 5It can be seen that the fixing slot has notches on one side facing the slot and on the other side away from the slot, so the hook is set on the slot wall between the two notches to facilitate deformation of the slot wall. Therefore, when the micro switch is inserted into the fixing slot, the micro switch squeezes the hook to deform the slot wall with the hook. When the micro switch is fully inserted into the fixing slot, the slot wall with the hook returns to its initial position and drives the hook to be fixed to the top surface of the micro switch to prevent the micro switch from leaving the fixing slot.

[0054] At the same time, in order to improve the structural strength of the groove wall with the hook, a reinforcing rib is provided on the outer side of the groove wall. The reinforcing rib is arranged close to the bottom of the fixing groove, which improves its structural strength while ensuring that the groove wall can be deformed.

[0055] Combination Figure 1 and Figure 5 As shown, in one embodiment of the utility model, two fixing grooves are provided and are respectively located on both sides of the slot along its extension direction, two micro switches are provided and are respectively arranged in the two fixing grooves, one micro switch is used to abut against the pushing part when opening the door, and the other micro switch is used to abut against the pushing part when resetting.

[0056] In this embodiment, two fixing grooves are respectively arranged at the two ends of the slot. The specific shape of the fixing grooves and the structure of the positioning pins arranged in the fixing grooves can refer to the description in the above embodiment, and no further description is given here. Among them, a micro switch is respectively arranged in each fixing groove. By arranging the two fixing grooves at the two ends of the slot, the driving member limits the reciprocating movement of the pushing part when driving the pushing part to return to reset, thereby ensuring that the pushing part can stably move within a preset range.

[0057] Combination Figure 2 As shown, in one embodiment of the utility model, the door opening device also includes a transmission assembly, which is arranged in the installation space. The transmission assembly includes an input gear, a first double gear and a second double gear that are meshed and connected in sequence. The input gear is sleeved on the output end of the driving member, and a rack is provided on the surface of the pushing part along its moving direction, and the end of the second double gear away from the first double gear is meshed and connected with the rack.

[0058] In this embodiment, the transmission assembly is arranged in the installation space, and the transmission assembly can convert the high-speed and low-torque power output by the motor into low-speed and high-torque power, so that the lower output torque of the driving member can be converted into a larger torque, and transmitted to the pushing part to drive the pushing part to move, so as to realize the smooth opening of the base station door panel. Therefore, the transmission assembly can reduce the load on the power output end of the motor and increase the service life of the motor.

[0059] The double gear is composed of two coaxial gears spaced apart from each other. When the transmission assembly is installed, the input gear can be meshed and connected with the lower gear of the first double gear, the upper gear of the first double gear can be meshed and connected with the lower gear of the second double gear, and then the upper gear of the second double gear can be meshed and connected with the rack of the pushing part.

[0060] At the same time, the upper and lower gears in the double gear have different diameters or numbers of teeth, so that the double gear can realize the conversion of high and low speeds and large and small torques. Compared with the connection structure using a single gear meshing in sequence, the solution provided by this embodiment can improve the transmission efficiency and transmission stability of the transmission assembly and reduce the loss of mechanical energy.

[0061] In addition, the number of the double gears is not limited to two in this embodiment, and can be adjusted accordingly according to actual needs. In other embodiments, the transmission assembly can also be a worm gear structure, as long as it can achieve high and low speed, large and small torque conversion.

[0062] Combination Figure 3 and Figure 4 As shown, in one embodiment of the utility model, the installation space includes a first installation cavity, a second installation cavity and a third installation cavity which are connected in sequence, the pushing portion is movably arranged in the first installation cavity, the transmission assembly is arranged in the second installation cavity, the driving member is arranged in the third installation cavity, a baffle is arranged between the second installation cavity and the third installation cavity, the baffle is provided with a socket connecting the second installation cavity and the third installation cavity, and the output end of the driving member passes through the socket and is drivingly connected to the transmission assembly.

[0063] In this embodiment, the installation space is designed to be a first installation cavity, a second installation cavity, and a third installation cavity that are connected in sequence, and the driving member, the transmission assembly, and the pushing part are arranged in three different spaces for easy assembly and fixation. The shapes of the first installation cavity, the second installation cavity, and the third installation cavity are designed according to the shapes of the pushing part, the transmission assembly, and the driving member, respectively, so that the shapes are adapted to each other. For example, the pushing part is a push rod-like structure that moves linearly in the direction toward the opening, so the shape of the first installation cavity is a linear groove, one end of the linear groove is connected to the opening, and one side of the linear groove is connected to the second installation cavity, so that the transmission assembly and the pushing part can be driven and matched. A slider is provided at the bottom of the linear groove to facilitate the sliding of the pushing part toward the opening.

[0064] The shape of the second installation cavity is cylindrical or U-shaped to match the installation of a transmission assembly including multiple gears to improve the compactness of the structure. When the driving member is a motor, since the shape of the motor is mostly cylindrical, the third installation cavity can also be designed to be cylindrical, and the third installation cavity has an installation opening on the side away from the baffle, and the driving member can be assembled in the third installation cavity through the installation opening. Therefore, the driving member is separated from the transmission assembly and the pushing part, and the driving member is fitted with the cavity wall of the third installation cavity to improve the stability of the driving member, thereby improving the stability of the entire driving process.

[0065] The third installation cavity is arranged below the second installation cavity to reduce the lateral dimension of the second installation cavity, so that the first installation cavity and the pushing part can be designed closer to the second installation cavity and the transmission assembly, thereby reducing the lateral dimension of the door opening device.

[0066] Furthermore, a plurality of positioning posts are provided on the baffle and the cavity wall of the second mounting cavity, and positioning grooves are opened on the positioning posts. Both ends of the first double gear and the second double gear are respectively inserted into the positioning grooves of the two positioning posts so that they can be rotatably arranged in the first mounting cavity.

[0067] The positioning columns arranged on the cavity wall and the baffle of the second installation cavity correspond to the gear shafts of each double gear, and the shape and size of the positioning grooves are adapted to the gear shafts.

[0068] Therefore, when installing the transmission assembly, the first duplex gear and the second duplex gear can be installed and positioned by the positioning column and the positioning groove, which improves the convenience of installation. At the same time, it can also reduce the axial deviation of the duplex gears caused during installation, and improve the matching accuracy and transmission stability between the first duplex gear and the second duplex gear. The positioning column is designed with high-strength engineering plastics or metal materials to ensure mechanical properties and wear resistance.
