Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaners, in particular to a dust cup structure of a vacuum cleaner opened by a connecting rod. Background Art

[0002] The cyclonic separation dust cup uses the cyclonic separation principle to separate dust and hair. This structure has a good dust and hair separation effect, but the cyclonic separation mechanism in the dust cup needs to be removed and then the dust, hair and other wastes need to be dumped out, which makes cleaning the garbage inconvenient. During this process, the dust and hair at the bottom of the dust cup mix and penetrate with the coarse particles in the cyclonic separation mechanism, resulting in a tight connection between the whole. The removal of the cyclonic separation mechanism and the discharge of waste are difficult and have great resistance. The process also requires manual operation and control, making the operation less neat and convenient. Some dust cups are equipped with a dust cup bottom cover at the bottom to enable the dust cup to be opened and the garbage to be dumped. If the locking structure button is accidentally touched, the dust cup bottom cover will suddenly detach quickly, and the dust cup will open, causing the contents to accidentally spill. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that the cyclone separation mechanism in the dust cup needs to be taken out and then the dust, hair and other wastes are dumped out, which makes it inconvenient to clean up the garbage. During the process, the dust and hair at the bottom of the dust cup are mixed and penetrated with the coarse particles in the cyclone separation mechanism, resulting in a tight overall connection. The removal of the cyclone separation mechanism and the discharge of waste are subject to great resistance and difficulty, and manual operation and control are required during the process, making the operation not neat and convenient. Some methods of opening and closing the bottom of the dust cup for dumping garbage and cleaning internal components have the problem that when the locking structure button is accidentally touched, the bottom cover of the dust cup is quickly and suddenly detached, the dust cup opens, and the contents are accidentally spilled. A vacuum cleaner dust cup structure that is opened by a connecting rod is provided.

[0004] The cam is secured to the bottom of the dust cup by means of a spring which is secured to the bottom of the dust cup by means of a spring which is secured to the bottom of the dust cup by means of a spring.

The first positioning section abuts against the bottom of the first ridge at the corresponding position of the dust cup, and its end extends inward horizontally or obliquely and is inserted into the side panel of the bottom cover of the dust cup. The second positioning section extends vertically or obliquely inward and is clamped in the slot between the first ridge and the second ridge at the corresponding position of the dust cup. The height of the first ridge is less than the height of the second ridge.

[0007] As a further description of the above technical solution:

[0008] The mainspring forms a pre-tightening force on the bottom cover of the dust cup to flip it downward or upward.

[0009] As a further description of the above technical solution:

[0010] An isolation groove is provided at the corresponding position of the dust cup in the locking structure. The notch of the isolation groove is horizontally oriented and is arranged around the locking structure. The center of the button is hinged in the isolation groove and the inner side of its upper end abuts against the reset spring.

[0011] As a further description of the above technical solution:

[0012] A slot is set at the front end of the dust cup, the first magnet is inserted into the slot and a non-magnetic T-shaped limit sleeve is set on the upper end thereof, and a limit block corresponding to the T-shaped limit sleeve extends inward from the top of the slot.

[0013] As a further description of the above technical solution:

[0014] A T-shaped positioning block is set at the front end of the dust cup bottom cover, and the second magnet is horizontally inserted into the T-shaped positioning block through a C-shaped positioning sleeve. A protruding block is set at the front end of the T-shaped positioning block, and the protruding block abuts against the front end of the C-shaped positioning sleeve to position it.

[0015] As a further description of the above technical solution:

[0016] A first sealing sleeve and a second sealing sleeve are provided at the upper end of the dust cup bottom cover, and the first sealing sleeve and the second sealing sleeve clamp and seal the inner and outer sides of the bottom of the dust cup.

[0017] As a further description of the above technical solution:

[0018] The installation height of the first sealing sleeve is greater than the installation height of the second sealing sleeve, and the tops of the first sealing sleeve and the second sealing sleeve both extend outward to form an inverted frustum-shaped sealing sleeve.

[0019] As a further description of the above technical solution:

[0020] A guide rail is provided at the bottom of the dust cup baffle, and the connecting piece is slidably connected to the guide rail and the two form a vertical limiting structure.

[0021] As a further description of the above technical solution:

[0022] An opening is provided at the bottom of the side wall of the inner sleeve, and an observation window is provided on the side wall of the dust cup.

[0023] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0024] 1. When the dust cup of the vacuum cleaner of the present invention is in use, the cyclone separation mechanism blocks large particles of dust and hair, and an air flow is formed in the inner sleeve, which blows the separated and collected large particles of dust and hair out of the inner sleeve through the opening, so that the large particles of dust and hair fall to the bottom of the dust cup; after the vacuum cleaner is used up, the collected waste can be observed through the observation window, and the garbage in the dust cup can be discharged; the upper end of the button is pressed so that the bottom of the button is disengaged from the positioning groove, and the dust cup bottom cover begins to flip and fall. Due to the spring, magnetic locking mechanism, the multi-section hinge between the dust cup bottom cover, the connecting rod, the dust cup baffle and the inner sleeve restrict the natural flipping and falling of the dust cup bottom cover, and the dust cup bottom cover will only fall to a certain extent or can only fall slowly. At the same time, the connecting piece slides on the guide rail to cooperate with the control of the dust cup bottom The cover opens at a speed and angle that controls the opening speed and angle, and abuts against the dust cup baffle to keep it closed. The dust cup bottom cover can be manually supported and pulled down to control the opening speed of the dust cup bottom cover, so that the dust and hair at the bottom of the dust cup are discharged in an orderly manner. At this time, the dust cup baffle is not opened. When the dust cup bottom cover is opened to a certain extent, the dust cup baffle opens, and the dust and hair remaining inside are discharged together with the coarse particulate matter collected in the cyclone separation mechanism. The above design makes the dust cup garbage discharge segmented, and the dust, hair and coarse particulate matter in the cyclone separation mechanism are discharged separately to avoid the two mixing and mutual infiltration, resulting in a tight overall combination and difficulty in discharge. The whole process is basically fully automatic, without too much manual control, making the operation neater and more convenient, meeting the user's dust cup usage experience and needs.

[0025] 2. The abutment between the first positioning section and the second positioning section of the mainspring against the first convex strip and the second convex strip creates a pre-tightening force on the dust cup and the bottom cover of the dust cup, which causes them to move away from each other (the first magnet and the second magnet exhibit magnetic attraction) or approach each other (the first magnet and the second magnet exhibit attraction or repulsion). Combined with the magnetic locking mechanism, the button and the positioning groove are more fully engaged, and it is effectively prevented that when the button is accidentally touched, the bottom cover of the dust cup is detached, the dust cup is opened, and the contents are accidentally spilled.

[0040] Example 1:

[0041] See also Figure 1-9 The present invention provides a technical solution: a dust cup structure of a vacuum cleaner opened by a connecting rod, comprising a dust cup 1 and a dust cup bottom cover 2, one side of the dust cup bottom cover 2 is hinged to one side of the bottom of the dust cup 1 through a positioning column 21, a spring 22 is sleeved on the positioning column 21, and the other side of the dust cup bottom cover 2 is connected to the other side of the bottom of the dust cup 1 through a locking structure 3, the locking structure 3 comprises a button 31 and a return spring 32, the bottom of the button 31 is clamped in the positioning groove 23 of the dust cup bottom cover 2, and a magnetic locking mechanism is further provided at the front end of the dust cup 1, the magnetic locking mechanism comprises a first magnet 15 vertically inserted at the front end of the dust cup 1 and a second magnet 25 horizontally inserted at the front end of the dust cup bottom cover 2, and an air inlet 6 is provided at the rear end of the dust cup 1. The air inlet 6 is connected to the cavity formed by the inner sleeve 16 in the dust cup 1, and a cyclone separation mechanism 7 is arranged in the cavity. A secondary separation mechanism 8 is arranged on the upper end of the cyclone separation mechanism 7. A dust cup baffle 5 is hinged on one side of the inner sleeve 16 through a connecting shaft 52. The dust cup baffle 5 is hinged on the top of the connecting rod 4 through a connecting piece 41, and the bottom end of the connecting rod 4 is hinged on the clamping structure on the upper surface of the dust cup bottom cover 2. After the dust cup is full of dust, the dust cup bottom cover is opened, and the connecting rod is pulled to open the partition of the dust cup that blocks dust and dump the garbage. At present, the dust cup of the vacuum cleaner with a similar structure has a good cyclone effect but it is inconvenient to clean the garbage. This structure can solve the disadvantage of inconvenience in cleaning the garbage, ensure the cyclone effect of the dust cup with a similar structure, and ensure that the garbage in the dust cup is easy to clean.

[0042] See also Figure 1 The dust cup 1 is provided with an isolation groove 13 at the corresponding position of the locking structure 3. The notch of the isolation groove 13 is horizontally oriented and is arranged around the locking structure 3. The center of the button 31 is hinged in the isolation groove 13 and the inner side of its upper end abuts on the reset spring 32 to ensure that the button firmly abuts against the positioning groove, avoiding the button from being accidentally touched, causing the bottom cover of the dust cup to open and the garbage to be spilled.

[0043] See also Figure 2 A slot 14 is provided at the front end of the dust cup 1, the first magnet 15 is inserted into the slot 14 and a non-magnetic T-shaped limit sleeve is provided on the upper end thereof, and a limit block 141 corresponding to the T-shaped limit sleeve is extended inward from the top of the slot 14, so that the first magnet is stably fixed at the front end of the dust cup.

[0044] See also Figure 7 A T-shaped positioning block 24 is provided at the front end of the dust cup bottom cover 2, and the second magnet 25 is horizontally inserted on the T-shaped positioning block 24 through a C-shaped positioning sleeve. A protruding block 241 is provided at the front end of the T-shaped positioning block 24, and the protruding block 241 abuts against the front end of the C-shaped positioning sleeve to position it, so that the second magnet is stably fixed at the front end of the dust cup bottom cover, and cooperates with the first magnet to realize a stable magnetic attraction or repulsion between the dust cup and the dust cup bottom cover, so that the dust cup is fixed when closed and the dust cup opening process is more stable.

[0045] Example 2:

[0046] See also Figure 4 、 6 On the basis of the above-mentioned embodiment 1, preferably, the ends of the spring 22 are respectively provided with a first positioning section 221 and a second positioning section 222, the first positioning section 221 abuts against the bottom of the first ridge 11 at the corresponding position of the dust cup 1 and its end extends horizontally or obliquely inward and is inserted into the side plate of the dust cup bottom cover 2, the second positioning section 222 extends vertically or obliquely inward and is clamped in the groove between the first ridge 11 and the second ridge 12 at the corresponding position of the dust cup 1, the height of the first ridge 11 is less than the height of the second ridge 12, the spring 22 forms a pre-tightening force on the dust cup bottom cover 2 to turn downward or upward, and the first positioning section and the second positioning section of the spring are against the first ridge 11 and the second ridge 12. The abutment formed between the first convex strip and the second convex strip creates a pre-tightening force on the dust cup and the dust cup bottom cover, which causes them to move away from each other (the first magnet and the second magnet show magnetic attraction) or approach each other (the first magnet and the second magnet show attraction or repulsion). In conjunction with the magnetic locking mechanism, the button and the positioning groove are more fully engaged, and it can effectively prevent the dust cup bottom cover from detaching and the dust cup from opening when the button is accidentally touched, causing the contents to spill accidentally. When the dust cup bottom cover is opened, in conjunction with other components, the natural flipping and falling of the dust cup bottom cover is restricted, so that the dust cup bottom cover will only fall to a certain extent or can only fall slowly, thereby allowing the dust and hair at the bottom of the dust cup to be discharged in an orderly manner.

[0047] Example 3:

[0048] See also Figure 5On the basis of the above-mentioned embodiment 1, preferably, a first sealing sleeve 26 and a second sealing sleeve 27 are provided at the upper end of the dust cup bottom cover 2, and the first sealing sleeve 26 and the second sealing sleeve 27 clamp and seal the inner and outer sides of the bottom of the dust cup 1. The installation height of the first sealing sleeve 26 is greater than the installation height of the second sealing sleeve 27. The tops of the first sealing sleeve 26 and the second sealing sleeve 27 extend outward to form an inverted frustum-shaped sealing sleeve, so that during the rotation and closing process of the dust cup bottom cover, the dust cup first contacts the first sealing sleeve to achieve airtightness inside the dust cup, and then the dust cup contacts the second sealing sleeve to achieve airtightness outside the dust cup, thereby ensuring the sealing effect of the dust cup and reducing the resistance during the closing process of the dust cup bottom cover, so that the dust cup bottom cover can be closed faster.

[0049] Example 4:

[0050] See also Figure 5 、 8 9. Based on the above-mentioned embodiment 1, preferably, a guide rail 51 is provided at the bottom of the dust cup baffle 5, and the connecting member 41 is slidably connected to the guide rail 51 and the two form a vertical limiting structure. The connecting member slides on the guide rail to cooperate with the control of the opening speed and angle of the dust cup bottom cover, and abuts against the dust cup baffle to keep it closed, so as to better realize the whole process basically fully automatic, without excessive manual control, and neat and convenient operation of segmented garbage discharge.

[0051] Embodiment 5:

[0052] See also Figure 1 On the basis of the above-mentioned embodiment 1, preferably, an opening is provided at the bottom of the side wall of the inner sleeve 16, so that the airflow formed in the inner sleeve will blow the separated and collected large particles of dust and hair out of the inner sleeve through the opening, so that the large particles of dust and hair fall to the bottom of the dust cup, thereby facilitating the segmented discharge of garbage, making the discharge of garbage from the dust cup more convenient and quick; an observation window 17 is provided on the side wall of the dust cup 1, so that the amount of collected waste can be observed through the observation window in real time, and whether to discharge the garbage in the dust cup can be selected, thereby avoiding the difficulty of garbage discharge caused by excessive accumulation of waste, and ensuring that garbage discharge is more convenient.

[0053] The working principle of the dust cup structure of the vacuum cleaner opened by the connecting rod in this embodiment includes: when the dust cup is closed (such as Figure 8), the return spring 32 pushes the upper end of the button 31 outward, and through the hinge structure of the button 31 and the isolation groove 13, the lower end of the button 31 is firmly abutted in the positioning groove 23. At the same time, the first positioning segment 221 and the second positioning segment 222 of the mainspring 22 form an abutment between the first ridge 11 and the second ridge 12, so that it forms a pre-tightening force on the dust cup and the dust cup bottom cover to deviate from each other (the first magnet and the second magnet show a magnetic attraction) or approach each other (the first magnet and the second magnet show an attractive force or a repulsive force). In conjunction with the magnetic locking mechanism, the button 31 and the positioning groove 23 are more fully engaged, and it is effectively prevented that when the button is accidentally touched, the bottom cover of the dust cup is detached, the dust cup is opened, and the contents are accidentally spilled. The clean air is then discharged upwards from the dust cup 1, and the coarse particles fall to the bottom of the cyclone separation mechanism 7. An air flow is formed at the bottom between the cyclone separation mechanism 7 and the inner sleeve 16, and the large particles of dust and hair separated and collected outside the cyclone separation mechanism 7 are blown out of the inner sleeve 16 through the opening of the inner sleeve 16, so that the large particles of dust and hair fall to the bottom of the dust cup. After the vacuum cleaner is used, the collected waste can be observed through the observation window 17, and the garbage in the dust cup can be discharged. When the upper end of the button 31 is pressed, the bottom of the button 31 is disengaged from the positioning groove 23, and the dust cup bottom cover 2 begins to flip and fall. Due to the spring 22 and the magnetic locking mechanism, the dust cup bottom cover and the connecting rod The multi-section hinge between the dust cup baffle and the inner sleeve restricts the natural flipping and falling of the dust cup bottom cover 2. The dust cup bottom cover will only fall to a certain extent or can only fall slowly. At the same time, the connecting piece 41 slides on the guide rail 51 to cooperate with the control of the opening speed and angle of the dust cup bottom cover, and abuts the dust cup baffle to keep it closed. The dust cup bottom cover can be manually supported and pulled down to control the opening speed of the dust cup bottom cover, so that the dust and hair at the bottom of the dust cup are discharged in an orderly manner. At this time, the dust cup baffle is not opened. When the dust cup bottom cover is opened to a certain extent, the dust cup baffle opens, and the dust and hair remaining inside are discharged together with the coarse particles collected in the cyclone separation mechanism. The above design makes the dust cup garbage discharge segmented, and the dust, hair and coarse particles in the cyclone separation mechanism are discharged separately to avoid the two mixing and mutual penetration, resulting in a tight overall combination and difficulty in discharge. The whole process is basically fully automatic, without too much manual control, making the operation more tidy and convenient, meeting the user's dust cup usage experience and needs.

[0054] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
