Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a dust collection base station and a dust collection component. Background Technology

[0002] Handheld vacuum cleaners are popular due to their small size, light weight, and ease of use. However, their size and weight also limit their dust storage capacity, requiring frequent emptying. To improve the convenience of handheld vacuum cleaners, some manufacturers have equipped them with dust collection stations, which contain a dust bag to collect dust. The handheld vacuum cleaner can be placed on the dust collection station, which then sucks up the dust from the vacuum cleaner into the dust bag.

[0003] For example, Chinese invention patent application publication number CN114601367A discloses a vacuum cleaner base station, including a main body connected to a vacuum cleaner. The main body is provided with a cover opening mechanism. The cover opening mechanism includes a drive block. The drive block is connected to a first drive wheel. The first drive wheel is connected to a second drive wheel through a first connecting rod. The second drive wheel is connected to a cover opening slider. The cover opening slider can contact the dust cup release button of the vacuum cleaner. The dust cup release button is connected to the bottom cover of the vacuum cleaner through a second connecting rod.

[0004] While conventional vacuum cleaner base stations provide a warning when the dust bag is full, if the user does not replace it in time, the dust collection process can still be restarted, easily leading to an overfilled dust bag. When the dust bag is replaced, dust may spill out, and the negative pressure suction device may also suck in dust when it restarts, potentially releasing dust outside the base station, polluting the environment and affecting the user experience. Summary of the Invention

[0005] In view of the above-mentioned problems existing in the prior art, the present invention provides a dust collection base station and a dust collection component, which enables the dust collection base station to avoid the dust bag from being too full.

[0006] To address the above problems, the technical solution provided by the embodiments of the present invention is as follows:

[0007] A dust collection base station, comprising:

[0008] ontology;

[0009] A dust collection assembly is disposed within the main body. The dust collection assembly has a first dust collection chamber, a first air inlet and a first air outlet communicating with the first dust collection chamber. The first air inlet can communicate with a vacuum cleaner. The dust collection assembly is used to draw dust from the vacuum cleaner through the first air inlet.

[0010] A dust bag is detachably disposed in the first dust collection chamber. The opening of the dust bag is connected to the first air inlet. The dust bag is used to filter the airflow flowing in from the first air inlet and collect dust.

[0011] A negative pressure suction component is disposed within the main body. The negative pressure suction component is connected to the first air outlet and is used to provide suction power to the dust collection component.

[0012] A first sensor is used to detect the air pressure in the first dust collection chamber;

[0013] The second sensor is used to detect whether the dust bag in the first dust collection chamber has been replaced.

[0014] A prompting device is disposed on the main body, and the prompting device is used to perform a prompting operation;

[0015] The controller is electrically connected to the negative pressure suction assembly, the first sensor, the second sensor, and the prompting device, respectively. The controller is configured as follows:

[0016] Based on the detection results of the first sensor, it is determined whether the dust collected by the dust bag has reached the target amount;

[0017] After determining that the dust collected by the dust bag has reached the target amount, if a control command is received to instruct the dust collection operation to be performed, it is determined whether the dust bag in the dust collection chamber should be replaced based on the detection result of the second sensor.

[0018] If not, the negative pressure suction component is disabled, and the prompting device is controlled to perform a prompting operation. This dust collection station can prevent the dust bag from becoming too full and can remind users to replace the dust bag as soon as possible through the prompting device, thus creating a better user experience.

[0019] In some embodiments, the second sensor is configured to detect whether the dust bag is installed in the first dust collection chamber, generating a first signal when the dust bag is detected to be installed in the first dust collection chamber, and generating a second signal when the dust bag is not detected to be installed in the first dust collection chamber; the controller is configured to:

[0020] After determining that the dust collected by the dust bag has reached the target amount, the dust bag in the dust collection chamber is replaced by determining whether the first signal, the second signal and the first signal sent by the second sensor are received in sequence.

[0021] The method of determining whether a dust bag needs to be replaced by detecting the disassembly of the dust bag is simple in logic and easy to implement.

[0022] In some embodiments, the first dust collection chamber has a snap-fit ​​position, and the dust bag includes a bag body and a snap-fit ​​plate connected to the bag body. The snap-fit ​​plate can snap into the snap-fit ​​position to fix the bag body to the first dust collection chamber.

[0023] The second sensor is located near the latching position and is configured to generate the first signal when the latching plate is detected to be latched into the latching position, and to generate the second signal when the latching plate is detected to be disengaged from the latching position.

[0024] The detection method can be used to determine whether the dust bag is installed in the first dust collection chamber by detecting the snap-fit ​​operation between the snap-fit ​​plate and the snap-fit ​​position. This method is not only accurate but also easy to implement.

[0025] In some embodiments, the dust collection assembly has a through hole extending into the first dust collection chamber; the second sensor includes a micro switch and a triggering component. The micro switch is disposed outside the first dust collection chamber and near the through hole, and the triggering component passes through the through hole. The triggering component is configured to: move along the through hole under the push of the snap-fit ​​plate and trigger the micro switch to generate the first signal; and reset when the snap-fit ​​plate is disengaged to generate the second signal. Detecting the snap-fit ​​operation between the snap-fit ​​plate and the snap-fit ​​position using a micro switch is not only low-cost but also accurate.

[0026] In some embodiments, the first air inlet is disposed on the top of the dust collection assembly, and the snap-fit ​​position is disposed near the top wall of the first dust collection chamber;

[0027] The snap-fit ​​plate has a second air inlet, and the bag body is located at the bottom of the snap-fit ​​plate with its opening connected to the second air inlet. When the snap-fit ​​plate is engaged at the snap-fit ​​position, the second air inlet is opposite to the first air inlet. The dust collection bag fits tightly with the dust collection assembly and is easy to disassemble.

[0028] In some embodiments, an air guide hole is provided in the first dust collection chamber at a target height, and the first dust collection chamber is connected to the negative pressure suction assembly through the air guide hole. The air guide hole is configured to be blocked by the dust bag when the dust height in the dust bag reaches the target height. The first sensor is used to detect the air pressure at the air guide hole.

[0029] By adjusting the height of the air vent, the target amount of dust collected by the dust bag can be accurately controlled. This overcomes the shortcomings of traditional detection methods, which can only detect air pressure changes when the dust bag is completely full of dust, and effectively avoids the phenomenon of overfilling the dust bag.

[0030] In some embodiments, the dust collection assembly includes:

[0031] A dust collection chamber, which has a second dust collection cavity, and the first air inlet and the first air outlet are disposed on the dust collection chamber and communicate with the second dust collection cavity;

[0032] An air guide bracket is disposed in the dust collection chamber, and the first dust collection cavity is formed in the air guide bracket. The air guide hole passes through the air guide bracket and communicates with the first air outlet through the second dust collection cavity.

[0033] In this way, the negative pressure suction component can draw air from the first dust collection chamber through the second dust collection chamber and the air guide hole. Once the air inlet of the air guide hole is blocked by the dust bag, the air pressure inside the air guide hole will drop rapidly, which can improve the detection sensitivity and accuracy.

[0034] In some embodiments, the air guide bracket has several through-holes, and the outer wall of the air guide bracket has several protruding ribs. Several channels are formed between the outer wall of the air guide bracket, the protruding ribs, and the inner wall of the second dust collection chamber. The first air outlet communicates with the air holes and the air guide holes through the channels. This ensures that the negative pressure suction assembly can provide sufficiently strong suction power to the first dust collection chamber, so as to ensure good dust collection effect throughout the entire service life of the dust bag.

[0035] In some embodiments, the controller is further configured to:

[0036] If the detection result of the second sensor determines that the dust bag in the dust collection chamber has been replaced, then the negative pressure suction assembly is activated.

[0037] A vacuuming assembly includes a vacuum cleaner and a dust collection base as described above. The dust collection base has a connection point on its body, and the vacuum cleaner can be connected to the connection point and communicate with the first dust collection chamber through a first air inlet. Since the dust collection base can prevent the dust bag from becoming too full, the vacuuming assembly using this dust collection base also has the aforementioned advantages.

[0038] The dust collection base station of this invention can determine whether the dust in the dust bag has reached the target amount based on the detection result of the first sensor. After determining that the dust collected by the dust bag has reached the target amount, if a control command is received to execute the dust collection operation, the dust bag is determined to be replaced based on the detection result of the second sensor. If it is determined that the dust bag has not been replaced, the negative pressure suction component is prohibited from being turned on to avoid continuing the dust collection operation, thereby avoiding the dust bag from becoming too full. In addition, the control prompt device performs a prompt operation to inform the user to replace the dust bag as soon as possible, which can form a better user experience.

[0052] To enable those skilled in the art to better understand the technical solutions of the embodiments of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] See Figures 1 to 3 As shown, an embodiment of the present invention discloses a dust collection base station, which includes a body 110, a dust collection component 120, a dust bag 130, a negative pressure suction component 140, a first sensor 150, a second sensor 160, and a controller 170.

[0054] The main body 110 may include, for example, a base 111, a support rod 112, and a support portion 113. The base 111 may have an assembly space. The bottom end of the support rod 112 can be connected to the base 111, and the top end of the support rod 112 can be connected to the support portion 113. The support portion 113 may have a connection position 114 for connecting the vacuum cleaner 200. Optionally, the connection position 114 may have a power interface and a suction port. When the vacuum cleaner 200 is assembled at the connection position 114, the vacuum cleaner 200 can be electrically connected to the power module in the main body 110 via the power interface. The power module can charge the vacuum cleaner 200 via the power interface. Furthermore, the dust collection space in the vacuum cleaner 200 can communicate with the suction port.

[0055] A dust collection assembly 120 is disposed within the main body 110. The dust collection assembly 120 has a first dust collection chamber 126, and a first air inlet 122 and a second air inlet 133 communicating with the first dust collection chamber 126. The first air inlet 122 can communicate with a vacuum cleaner 200. The dust collection assembly 120 is used to suck dust from the vacuum cleaner 200 through the first air inlet 122. Optionally, the dust collection assembly 120 can be disposed in the assembly space of the base 111. The support rod 112 can be tubular, and the first air inlet 122 can communicate with the suction port through the support rod 112 to suck dust from the dust collection space of the vacuum cleaner 200.

[0056] A dust bag 130 is detachably disposed within the first dust collection chamber 126. The opening of the dust bag 130 communicates with the first air inlet 122. The dust bag 130 is used to filter the airflow flowing into the first air inlet 122 and collect dust. Optionally, after the airflow flows into the first dust collection chamber 126 through the first air inlet 122, it can first flow into the dust bag 130. After being filtered by the dust bag 130, the dust is collected in the dust bag 130, and the clean airflow flows out from the dust bag 130.

[0057] A negative pressure suction assembly 140 is disposed within the main body 110. The negative pressure suction assembly 140 is connected to the first air outlet 123 and is used to provide suction power for the dust collection assembly 120. Optionally, the negative pressure suction assembly 140 may also be disposed in the assembly space. Optionally, the negative pressure suction assembly 140 may include a negative pressure fan, and a second air outlet may be provided on the base 111. The inlet and outlet of the negative pressure fan may be connected to the first air outlet 123 and the second air outlet, respectively. The negative pressure fan can draw air from the first dust collection chamber 126 through the first air outlet 123, forming a negative pressure in the first dust collection chamber 126 to provide suction power for the first dust collection chamber 126. Then, the airflow is discharged through the second air outlet.

[0058] A first sensor 150 may be disposed in a first dust collection chamber 126, and the first sensor 150 is used to detect the air pressure in the first dust collection chamber 126. Optionally, the first sensor 150 may include a pressure sensor.

[0059] The second sensor 160 is used to detect whether the dust bag 130 in the first dust collection chamber 126 has been replaced. Optionally, the second sensor 160 can detect whether the dust bag 130 has been replaced by detecting the removal and installation of the dust bag 130, or the second sensor 160 can detect whether the dust bag 130 in the first dust collection chamber 126 has been replaced by detecting the amount of dust in the dust bag 130.

[0060] A prompting device is disposed on the main body 110, and the prompting device is used to perform prompting operations. Optionally, the prompting device may be disposed on the base 111, or on the support part 113 or the support rod 112. Optionally, the prompting device may include various devices that perform prompting operations through sound, light, vibration, etc., and the prompting device includes, but is not limited to, indicator lights, buzzers, speakers, displays, etc.

[0061] The controller 170 is electrically connected to the negative pressure suction assembly 140, the first sensor 150, the second sensor 160, and the prompting device, respectively. The controller 170 is configured as follows:

[0062] Based on the detection results of the first sensor 150, it is determined whether the dust collected by the dust bag 130 has reached the target amount;

[0063] After determining that the dust collected by the dust bag 130 has reached the target amount, if a control command for instructing the dust collection operation is received, it is determined whether the dust bag 130 in the dust collection chamber should be replaced based on the detection result of the second sensor 160.

[0064] If not, then the negative pressure suction assembly 140 is prevented from being turned on, and the prompting device is controlled to perform a prompting operation;

[0065] If so, the prompting device is turned off, and the negative pressure suction assembly 140 is turned on to perform dust collection.

[0066] Optionally, the first sensor 150 can send the detected pressure value to the controller 170. The controller 170 can compare the pressure value with a preset threshold. If the detected pressure value meets the preset threshold, it is determined that the dust bag 130 has reached the target amount; if the detected pressure value does not meet the preset threshold, it is determined that the dust bag 130 has not reached the target amount. Alternatively, the first sensor 150 can send a dust full signal to the controller 170 when the detected pressure value meets the preset threshold. Upon receiving the dust full signal, the controller 170 determines that the dust collected by the dust bag 130 has reached the target amount. Optionally, the target amount can be a target height, a target weight, or a target volume.

[0067] Optionally, the dust collection base station may also include operating components such as operation buttons or an operation panel, through which the user can send control commands to the controller 170. Alternatively, when the vacuum cleaner 200 is connected to the connection position 114, it can be connected to the power interface. When the power module detects that the power interface is connected to the vacuum cleaner 200, it can send control commands to the controller 170, instructing the controller 170 to automatically perform the vacuuming operation.

[0068] Optionally, after determining that the dust bag 130 has collected a target amount of dust, the controller 170 continuously controls the prompting device to perform a prompting operation.

[0069] The dust collection base station of this embodiment of the invention can determine whether the dust in the dust bag 130 has reached the target amount based on the detection result of the first sensor 150. After determining that the dust collected by the dust bag 130 has reached the target amount, if a control command is received to execute the dust collection operation, the dust bag 130 is determined to be replaced based on the detection result of the second sensor 160. If it is determined that the dust bag 130 has not been replaced, the negative pressure suction component 140 is prohibited from being turned on to avoid continuing the dust collection operation, thereby preventing the dust bag 130 from becoming too full. In addition, the control prompt device performs a prompt operation to inform the user to replace the dust bag 130 as soon as possible, which can form a better user experience.

[0070] Cooperate Figure 2 As shown, in some embodiments, an air guide hole 127 is provided in the first dust collection chamber 126 at a target height. The first dust collection chamber 126 is connected to the negative pressure suction assembly 140 through the air guide hole 127. The air guide hole 127 is configured to be blocked by the dust bag 130 when the dust height in the dust bag 130 reaches the target height. The first sensor 150 is used to detect the air pressure at the air guide hole 127. By adjusting the height of the air guide hole 127, the target amount of dust collected by the dust bag 130 can be accurately controlled, overcoming the defect of traditional detection methods that can only detect air pressure changes when the dust bag 130 is completely full of dust, and effectively avoiding the phenomenon of the dust bag 130 being overfilled.

[0071] In some embodiments, the dust collection assembly 120 may include a dust collection chamber 121 and an air guide bracket 125. The dust collection chamber 121 may have a second dust collection cavity 124. The first air inlet 122 and the first air outlet 123 are disposed on the dust collection chamber 121 and communicate with the second dust collection cavity 124. The air guide bracket 125 may be disposed within the dust collection chamber 121, forming the first dust collection cavity 126. The air guide hole 127 penetrates the air guide bracket 125 and communicates with the first air outlet 123 through the second dust collection cavity 124. In this way, the negative pressure suction assembly 140 can draw air from the first dust collection cavity 126 through the second dust collection cavity 124 and the air guide hole 127. Once the air inlet of the air guide hole 127 is blocked by the dust bag 130, the air pressure inside the air guide hole 127 will drop rapidly, which can improve detection sensitivity and accuracy.

[0072] In some embodiments, the air guide bracket 125 has a plurality of through ventilation holes 129, the outer wall of the air guide bracket 125 has a plurality of protruding ribs 128, and a plurality of channels are formed between the outer wall of the air guide bracket 125, the protruding ribs 128 and the inner wall of the second dust collection chamber 124, and the first air outlet 123 communicates with the ventilation holes 129 and the air guide holes 127 through the channels. In this way, after the dust bag 130 collects dust at the bottom, it will stick to the inner wall of the air guide bracket 125, blocking the vent 129 at the bottom of the air guide bracket 125. However, since the top of the dust bag 130 is not yet full of dust, the negative pressure suction assembly 140 can still draw air from the first dust collection chamber 126 through the channel and the vent 129 located in the middle or upper part of the air guide bracket 125, thereby ensuring that the negative pressure suction assembly 140 can provide a sufficiently strong suction force to the first dust collection chamber 126, so as to ensure that the dust bag 130 can have a good dust collection effect throughout its entire service life.

[0073] Optionally, the first air inlet 122 can be located on the top wall of the second dust collection chamber 124, and the first air outlet 123 can be located in the middle of the bottom wall of the second dust collection chamber 124. The top of the air guide bracket 125 is open, and the first dust collection chamber 126 inside the air guide bracket 125 is connected to the first air inlet 122 through the open. The outer side wall and the bottom surface of the air guide bracket 125 can be provided with protruding ribs 128. The protruding ribs 128 on the outer side wall can extend vertically, and adjacent protruding ribs 128 on the outer side wall can be arranged parallel to each other or substantially parallel to each other. The protruding ribs 128 on the bottom surface can extend from the middle of the bottom surface to the periphery of the bottom surface to form channels extending from the middle of the bottom surface to the periphery in various directions, thereby enabling the suction of airflow from various directions.

[0074] Optionally, a first opening may be provided on the side of the dust collection chamber 121, and a second opening opposite to the first opening may be provided on the side of the air guide bracket 125, through which the dust bag 130 can be loaded into the first dust collection chamber 126. Optionally, a third opening opposite to the first opening may be provided on the side of the base 111, and a cover plate may be provided at the third opening. The cover plate may be configured to simultaneously seal the first opening and the third opening. For example, a first sealing part may be provided at the first opening, and a second sealing part may be provided on the inner side of the cover plate. When the cover plate is closed, the third opening is sealed, and the second sealing part is sealed to the first sealing part to seal the first opening. This simplifies the structure of the base 111.

[0075] In some embodiments, the second sensor 160 is configured to detect whether the dust bag 130 is installed in the first dust collection chamber 126, generating a first signal when the dust bag 130 is detected to be installed in the first dust collection chamber 126, and generating a second signal when the dust bag 130 is not detected to be installed in the first dust collection chamber 126; the controller 170 is configured to:

[0076] After determining that the dust collected by the dust bag 130 has reached the target amount, the dust bag 130 in the dust collection chamber is replaced by determining whether the first signal, the second signal and the first signal sent by the second sensor 160 are received in sequence.

[0077] In other words, the method determines whether the dust bag 130 has been replaced by detecting the disassembly behavior of the dust bag 130. The judgment logic of this method is simple and easy to implement.

[0078] In some embodiments, the first dust collection chamber 126 has a snap-fit ​​position, and the dust bag 130 includes a bag body 132 and a snap-fit ​​plate 131 connected to the bag body 132. The snap-fit ​​plate 131 can snap into the snap-fit ​​position to fix the bag body 132 to the first dust collection chamber 126. A second sensor 160 is disposed near the snap-fit ​​position. The second sensor 160 is configured to generate the first signal when it detects that the snap-fit ​​plate 131 is snapped into the snap-fit ​​position, and to generate the second signal when it detects that the snap-fit ​​plate 131 has disengaged from the snap-fit ​​position. By detecting the snap-fit ​​operation of the snap-fit ​​plate 131 with the snap-fit ​​position, the installation of the dust bag 130 in the first dust collection chamber 126 is detected. The component detection result is accurate and easy to implement.

[0079] Cooperate Figures 4 to 7As shown, in some embodiments, the dust collection assembly 120 has a through hole extending into the first dust collection chamber 126; the second sensor 160 includes a micro switch 161 and a triggering component 162. The micro switch 161 is disposed outside the first dust collection chamber 126 and near the through hole. The triggering component 162 passes through the through hole. The triggering component 162 is configured to move along the through hole under the push of the snap-fit ​​plate 131 and trigger the micro switch 161, so that the micro switch 161 generates the first signal, such as... Figure 4 and Figure 5 As shown; when the latch plate 131 is disengaged, it can be reset to allow the micro switch 161 to generate the second signal, as shown. Figure 6 and Figure 7 As shown. Using a micro switch 161 to detect the engagement operation of the snap-fit ​​plate 131 with the snap-fit ​​position is not only low-cost but also accurate.

[0080] Optionally, a through hole can be made in the top wall of the dust collection chamber 121, extending to the snap-fit ​​position. A micro-switch can be positioned at the top of the dust collection chamber 121, opposite the through hole. A triggering component 162 can pass through the through hole, with its top end facing the spring of the micro switch 161, and its bottom end extending to the snap-fit ​​position. Two opposing sliding grooves can be provided near the top wall inside the first dust collection chamber 126, extending laterally. The two sides of the snap-fit ​​plate 131 can be slidably connected to the two sliding grooves respectively. Sliding along the sliding grooves can push the triggering component 162 upwards vertically, thereby triggering the spring of the micro switch 161, causing the micro switch 161 to generate a first signal. After the snap-fit ​​plate 131 disengages from the sliding groove, the triggering component 162, under its own weight or the elastic force of the spring, can move downwards vertically, causing the spring of the micro switch 161 to spring open, generating a second signal.

[0081] Optionally, the bottom end of the trigger component 162 may be provided with a guide ramp so that the snap plate 131 can smoothly and progressively lift the trigger component 162.

[0082] In some embodiments, the first air inlet 122 is disposed on the top of the dust collection assembly 120, and the snap-fit ​​position is disposed near the top wall of the first dust collection chamber 126. A second air inlet 133 is provided on the snap-fit ​​plate 131, and the bag body 132 is located at the bottom of the snap-fit ​​plate 131 with its opening connected to the second air inlet 133; when the snap-fit ​​plate 131 is snapped into the snap-fit ​​position, the second air inlet 133 is opposite to the first air inlet 122. The dust collection bag 130 fits tightly with the dust collection assembly 120 and is easy to disassemble.

[0083] See Figure 1As shown, this embodiment of the invention provides a vacuuming assembly, which includes a vacuum cleaner 200 and a dust collection base station 100 as described in any of the above embodiments. The body 110 of the dust collection base station 100 is provided with a connection position 114. The vacuum cleaner 200 can be connected to the connection position 114 and communicate with the first dust collection chamber 126 through the first air inlet 122.

[0084] Since the dust collection base station 100, after determining that the dust bag 130 has collected the target amount of dust, receives a control command to perform a dust collection operation and confirms that the dust bag 130 has not been replaced, it prohibits the activation of the negative pressure suction component 140 to avoid continuing the dust collection operation, thereby preventing the dust bag 130 from becoming too full. Furthermore, the control prompt device performs a prompt operation to inform the user to replace the dust bag 130 as soon as possible, resulting in a better user experience. Therefore, the suction component using the aforementioned dust collection base station 100 also has the above advantages.

[0085] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
