Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum cleaners, and in particular to a dust cup cover mechanism with automatic opening and closing and a base station type vacuum cleaner. Background Technique
[0002] When a base station type vacuum cleaner is placed in the base station, the base station needs to suck the dust stored in the dust cup into the base station through the suction force provided by the suction motor. The premise for realizing this function is that the dust cup cover at the connection between the base station and the dust cup needs to be automatically opened when the base station sucks dust and automatically closed after the dust suction is completed. Therefore, the design of realizing the automatic opening and closing function of this dust cup cover is a key design point in the design of the base station type vacuum cleaner. Currently, the opening and closing structure between the dust cup cover and the dust cup body of the existing products on the market is that there are multiple magnets and movable buckles on both the dust cup cover and the dust cup body. The implementation logic of this structure is as follows: After the vacuum cleaner is placed in the base station in the standby state, the charging terminals of the vacuum cleaner and the base station are automatically aligned and connected. The base station determines that the vacuum cleaner has been placed in the base station through the conduction of the charging terminals. At this time, after the base station automatically issues a dust collection instruction, the suction motor of the base station starts. The base station sealing piece and the dust cup cover of the vacuum cleaner are opened under the action of the suction force (the suction force of the suction motor is greater than the resultant force of the magnetic attraction force between the dust cup cover and the dust cup body and the locking force of the movable buckle). The dust in the dust cup is sucked out from the opening of the dust cup cover, enters the air duct of the base station, and then enters the dust collection bag in the base station. After the dust collection action is completed, the suction motor of the base station shuts down, and the opening and tightening suction force acting on the base station sealing piece and the dust cup cover of the vacuum cleaner disappears. The base station sealing piece automatically returns to its original position and closes. The dust cup cover of the vacuum cleaner is semi-returned to the position where the dust cup cover and the dust cup body are about to fit under the action of the magnetic attraction force. At this time, the dust cup cover is blocked by the movable buckle, not locked, and the dust cup body is not completely fitted. The base station sends a dust collection completion message to the vacuum cleaner through the charging terminal. After receiving this message, the vacuum cleaner starts the suction motor of the vacuum cleaner for a few seconds. Through the reverse suction force provided by the suction motor of the vacuum cleaner, the dust cup cover pushes open the movable buckle, and finally is locked by the movable buckle, and the dust cup cover completely fits the dust cup body and achieves airtight sealing.
[0003] The existing designs for the automatic opening and closing function of the dust cup lid in base - type vacuum cleaners have the following problems: 1. Ferromagnets and movable buckles and other structures need to be set on both the dust cup lid and the dust cup body, with complex structures and relatively high manufacturing and assembly costs; 2. After the vacuum cleaner finishes dust collection at the base station, it needs to receive the dust collection completion information from the base station and then start the suction motor of the vacuum cleaner to suck the dust cup lid tightly and pop open the movable buckle, and finally make the dust cup lid return to the locked position. In this process, the terminals for the base station to transmit and receive instructions, the terminals for the vacuum cleaner to receive instructions, and the charging function of the vacuum cleaner when placed in the dust collection station will conflict with the transmission and reception of instructions. Therefore, this design will increase the cost and complexity of software and hardware, and increase the probability of errors (such as software program errors causing the dust cup lid not to be locked, the vacuum cleaner not charging, and the user taking out the vacuum cleaner before dust collection is completed, resulting in the dust cup lid not being locked and dust leakage, etc.), with poor reliability in use and a bad user experience.

Specific embodiments
[0029] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is given with reference to the accompanying drawings.
[0030] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship during the normal use of the product.
[0031] The terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one of such features.
[0032] Referring to Figures 1 - 12 , an embodiment of the present utility model provides a dust cup cover mechanism capable of automatic opening and closing, including: a dust cup 2 on a vacuum cleaner 1 and a base station 3 detachably connected to the vacuum cleaner 1. An air outlet 201 is provided on the dust cup 2, and a dust cup cover 202 that can be opened / closed is movably arranged at the air outlet 201. A base station suction motor 301 communicated with the dust cup cover 202 is provided on the base station 3. The dust cup cover 202 in the unlocked state is driven to open by the suction force of the base station suction motor 301. A first elastic member 203 for driving the dust cup cover 202 to close is provided on the dust cup 2. It is worth mentioning that: the acting force for opening the dust cup cover 202 when the base station suction motor 301 is started is greater than the acting force for driving the dust cup cover 202 to close by the first elastic member 203, so as to ensure that the dust cup cover 202 can be driven to open when the base station suction motor 301 is started; a locking / unlocking mechanism for locking / unlocking the dust cup cover 202 in the closed state is provided on the dust cup 2. The locking / unlocking mechanism includes a locking member 30 and a second elastic member 4. The locking member 30 is movably arranged on the dust cup 2 and has a locking position and an unlocking position during the movement process. The second elastic member 4 is used to drive the locking member 30 to the locking position to block the dust cup cover 202 in the closed state. An unlocking boss 302 for driving the locking member 30 to the unlocking position is provided on the base station 3; when the vacuum cleaner 1 is connected to the base station 3, the unlocking boss 302 pushes the locking member 30 to the unlocking position; the present utility model is provided with a locking / unlocking mechanism, and the dust cup cover is automatically unlocked after the vacuum cleaner is connected to the base station, so that the dust cup cover can be automatically opened during dust collection (that is, when the vacuum cleaner 1 is connected to the base station 3 and the base station suction motor 301 is started). When the dust collection is completed (that is, when the base station suction motor 301 is turned off), the dust cup cover can automatically close due to the loss of the suction force of the base station suction motor 301 and under the elastic force of the first elastic member 203, and the dust cup cover is automatically locked after the vacuum cleaner is separated from the base station, without relying on the suction force of the vacuum cleaner suction motor on the vacuum cleaner 1 to close and lock the dust cup cover. The structure is simple and reliable, the production cost is low, and it is convenient to use.
[0033] Referring to Figures 1 - 5, the dust cup cover 202 is hinged to the dust cup 2. The first elastic member 203 is a torsion spring, with a simple structure and low production cost. It does not use the relatively expensive ferromagnetic body in the previous structure, avoiding the increase in software and hardware costs caused by the base station sending instructions to the vacuum cleaner to close and lock the dust cup cover after dust collection. It adopts a simple and reliable mechanical structure to simplify the process of automatic dust collection and opening / closing the dust cup cover of the vacuum cleaner, so as to increase product reliability and reduce the after-sales maintenance cost of the product. A first sealing ring 2021 corresponding to the dust outlet 201 is provided on the dust cup cover 202 to avoid dust leakage after the dust cup cover 202 is closed. An inlet 303 is provided on the base station 3. The inlet 303 is arranged below the dust outlet 201. A communication cavity 204 for connecting the dust outlet 201 and the inlet 303 is provided on the dust cup 2. One end of the dust cup cover 202 is hinged to the inner wall of the communication cavity 204. An opening 205 is provided on the lower side of the communication cavity 204.

The inlet 303 is opened on the upper side of the transition bin 7. The base station suction motor is arranged below the dust bag 6. A sealing member 5 for blocking / opening the inlet 303 is provided on the base station 3. Under normal conditions, the sealing member 5 abuts against the inlet 303 for sealing and blocking to achieve the dust-proof and waterproof function of the inlet 303. When the base station suction motor 301 is started, the sealing member 5 is driven by the suction force of the base station suction motor 301 to open the inlet 303, so that dust and other garbage in the dust cup 2 can enter the dust bag in the base station 3 for storage, and the structural design is reasonable.
[0034] Refer to Figure 2 , Figure 3 , Figure 5 and Figure 12 , the sealing member 5 is a sealing block made of soft rubber material. The soft rubber material is a soft material with good sealing performance such as rubber material or silicone material, etc. A bending deformation groove 501 is provided on the sealing member 5 to facilitate the deformation and opening of the sealing member 5 under the action of suction force. Before assembly, the sealing member 5 includes a horizontally extending mounting block 502 and a blocking block 503 inclined upward. The mounting block 502 is fixedly installed on the transition bin of the base through bolts. The sealing block can also adopt a torsion spring hinged method to achieve the switching function. The upward inclination makes the blocking block 503 have an upward abutting sealing force on the inlet 303 itself. During assembly and when the base station suction motor 301 is closed, the blocking block 503 abuts against the inlet 303 horizontally for sealing. When the base station suction motor 301 is started, it drives the blocking block 503 to turn downward and deform to open the inlet 303, with a simple structure and convenient use.
[0035] Refer to Figures 1 - 3, the locking member 30 is a locking rod slidably arranged on the dust cup 2. A stop block 305 is arranged at one end of the locking member 30 close to the dust cup cover 202. A locking groove 206 corresponding to the stop block 305 is arranged on the dust cup cover 202. When the vacuum cleaner is placed and connected to the base station, the unlocking boss pushes the locking member 30 and the stop block 305 out of the locking groove 206 for unlocking. At this time, starting the suction motor of the base station can drive the dust cup cover to open; when the vacuum cleaner is separated from the base station, the locking member 30 and the stop block 305 are snapped into the locking groove 206 under the action of the second elastic member to stop the dust cup cover from opening, and the use is reliable; a guiding inclined surface 3051 for facilitating the introduction into the locking groove 206 is arranged on the stop block 305, so that the stop block 305 can be smoothly introduced into the locking groove 206; an installation cavity 207 is arranged on the dust cup 2, the locking member 30 is slidably installed in the installation cavity 207 in the horizontal direction, the second elastic member 4 is placed in the installation cavity 207, the second elastic member 4 is a compression spring, one end of the second elastic member 4 abuts against the dust cup 2, and the other end of the second elastic member 4 abuts against the locking member 30. The structure is simple and the production cost is low.
[0036] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 9 , a pushing inclined surface 3021 for pushing the locking member 30 to unlock is arranged on the unlocking boss 302, and a pushed inclined surface 306 corresponding to the pushing inclined surface 3021 is arranged on the locking member 30. Through the cooperation of the pushing inclined surface 3021 and the pushed inclined surface 306, the unlocking boss 302 can drive the locking member 30 to slide and unlock.
[0037] Compared with the prior art, the dust cup cover mechanism of the present utility model that can be automatically switched is provided with a locking and unlocking mechanism. After the vacuum cleaner is connected to the base station, the dust cup cover is automatically unlocked, so that the dust cup cover can be automatically opened during dust collection, and the dust cup cover can be automatically closed when the dust collection is completed. Moreover, the dust cup cover is automatically locked after the vacuum cleaner is separated from the base station. The structure is simple and reliable, the production cost is low, and the use is convenient; there is no need to use relatively expensive structures such as ferromagnetic bodies in the previous structures, avoiding the increase in software and hardware costs caused by the base station sending instructions to the vacuum cleaner to complete the process of closing and locking the dust cup cover after the dust collection is completed; a simple and reliable mechanical structure is adopted to simplify the process of automatic dust collection and opening and closing the dust cup cover of the vacuum cleaner, so as to increase the product reliability and reduce the after-sales maintenance cost of the product; a guiding inclined surface for facilitating the introduction into the locking groove is arranged on the stop block, so that the stop block can be smoothly introduced into the locking groove; when the vacuum cleaner is placed and connected to the base station, the unlocking boss pushes the locking member and the stop block out of the locking groove for unlocking. At this time, starting the suction motor of the base station can drive the dust cup cover to open; when the vacuum cleaner is separated from the base station, the locking member and the stop block are snapped into the locking groove under the action of the second elastic member to stop the dust cup cover from opening, and the use is reliable.
[0038] The present utility model further provides a base - type vacuum cleaner, which includes the above - mentioned dust cup cover mechanism with automatic opening and closing.

When the vacuum cleaner is placed in the base, it is necessary to manually judge whether to start the dust collection operation. When the user wants to start the dust collection operation, the manual dust collection switch needs to be pressed to start the dust collection operation of the base. After the base finishes dust collection, the base automatically enters the original set dust collection mode standby state.
