TECHNICAL FIELD

[0001] The present application relates to the technical field of dust collectors, in particular to an energy-saving modular dust collector with air inlet detection function. BACKGROUND

[0002] A dust collector is a cleaning appliance that uses an electric motor to drive a fan to rotate at high speed, generating negative pressure inside the machine, thereby sucking air from the outside together with dust, debris and other sundries through the suction nozzle / suction head into the machine. Household cleaning dust collectors generally use battery packs for power supply and are designed as wireless handheld dust collectors.

[0003] The existing handheld dust collector is powered by a battery pack, which results in limited endurance time. Therefore, operating gears are provided to allow a person to select different operating gears of the motor according to the resistance of the surface to be cleaned, so as to save energy while ensuring cleaning effect, thereby prolonging the use time of the dust collector. For example, for low-resistance surfaces such as hard floors, the suction demand is low, and the motor can operate at low power; and for high-resistance surfaces such as carpets, the suction demand is high, and the motor needs to operate at high power to ensure the cleaning effect.

[0004] Therefore, the existing handheld dust collector cannot automatically adjust the power of the motor, resulting in high power consumption and short endurance time of the dust collector. SUMMARY

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example 1

[0036] Please see Figures 1-14 This invention provides a technical solution: an energy-saving modular vacuum cleaner with air intake detection function, comprising: The vacuum cleaner main unit 1 includes a housing 11 and a controller. The housing 11 is provided with a hook plate 12, a contact plate 13, a connecting seat 14 and a first locking plate 15. The hook plate 12 extends outward from the housing 11 and is an arc-shaped plate. The first locking plate 15 is rotatably connected to the connecting seat 14. A second torsion spring is sleeved on the rotating shaft of the first locking plate 15. The elastic force of the second torsion spring is used to achieve self-reset after unlocking. The dust cup module 2 includes a dust cup shell 21 and a filter assembly 22. The filter assembly 22 is detachably installed inside the dust cup shell 21. The dust cup shell 21 is provided with an air inlet connector 23, and the air inlet connector 23 is provided with an air inlet channel that connects to the internal cavity of the dust cup shell 21. The thermal wind speed sensor 3 is electrically connected to the controller. The thermal wind speed sensor 3 includes a heating sensor and a reference sensor symmetrically arranged on both sides of the air inlet channel. The battery pack 4 is detachably mounted on the housing 11. The end of the battery pack 4 is provided with a first notch 41 that matches the shape of the connecting seat 14. The end face of the first notch 41 is a first arc surface 411, which contacts the surface of the dust cup housing 21. The dust cup housing 21 is provided with a plug groove 211, a contact 212 and a locking seat 213. The plug groove 211 and the contact 212 are symmetrically arranged on both sides of the dust cup housing 21. The end of the plug groove 211 is provided with a second arc surface 2111. The locking seat 213 is inserted into the connecting seat 14. The hook 151 of the first locking plate 15 is fastened to the groove of the locking seat 213.

[0037] The vacuum cleaner adopts a modular design, and the vacuum cleaner main unit 1, dust cup module 2 and battery pack 4 can be separated. The dust cup shell 21 and filter component 22 in the dust cup module 2 can be quickly separated. On the other hand, the snap-fit ​​between the battery pack 4 and the connecting seat 14 not only uses the positioning structure of the dust cup module 2 to position the battery pack 4, but also the first arc surface 411 on the end face of the battery pack 4 to prevent collision damage during assembly contacts and positions the dust cup module 2. This makes the modular design of the vacuum cleaner convenient to assemble, easy to disassemble and maintain, and hides the splicing gaps.

[0038] The dust cup housing 21 is also provided with a positioning block 216, and the housing 11 is provided with a slot 111 whose position corresponds to the positioning block 216. The insertion and locking of the positioning block 216 and the slot 111 improves the position locking effect when the dust cup module 2 is installed.

[0039] The connector 14 has symmetrically arranged third arc surfaces 141 on both sides to further prevent end collision damage when the battery pack 4 is spliced ​​with the connector 14.

[0040] The battery pack housing has symmetrically arranged mounting slots 43 on both sides, with one end of each slot extending to the first arc surface 411. The housing 11 has mounting plates 114 whose shape matches the battery pack housing. During installation, the mounting plates 114 are inserted into the mounting slots 43 of the battery pack housing. After the battery pack 4 is horizontally slid into place, it is locked by the locking tongue 421 of the button 42 engaging with the groove 112.

[0041] Working principle: When the vacuum cleaner is working, the airflow enters the dust cup shell 21 through the air inlet channel of the air inlet connector 23. The heating sensor (HS) and the reference sensor (RS) in the thermal wind speed sensor 3 work together to eliminate the interference of ambient temperature and improve the measurement accuracy. The controller of the vacuum cleaner host 1 adjusts the motor power according to the wind speed detected by the thermal wind speed sensor 3. If the wind speed is >5m / s, it is judged as a low resistance and low suction demand condition, and the motor power is reduced from 400W to 150W; conversely, if the detected wind speed is <2m / s, the motor power is increased. The motor power is adjusted to adapt to the ground resistance to avoid wasting motor power and improve the vacuum cleaner's battery life. This solves the problem of high power consumption and short battery life caused by the inability of existing handheld vacuum cleaners to automatically adjust the motor power.

[0042] Meanwhile, the energy-saving vacuum cleaner adopts a modular design. When the dust cup module 2 is installed, the upper insertion slot 211 of the dust cup shell 21 is inserted into the hook plate 12 on the vacuum cleaner main unit 1, and the bottom locking seat 213 is inserted into the connecting seat 14 and locked by the hook 151 of the first locking plate 15. The hook plate 12 securely locks the upper end of the dust cup module 2, thereby maintaining contact between the contact point 212 on the back of the dust cup module 2 and the contact piece 13 on the shell 11, so as to realize the power supply of the thermal wind speed sensor 3 and the signal transmission between the controller. Example 2

[0043] Based on the above embodiments, the following improved technical solutions are further made in this embodiment: an annular retaining ring 214 is provided on the inner wall of the dust cup shell 21, a stepped surface with a shape matching the annular retaining ring 214 is provided on the filter assembly 22, and a semi-circular handle 221 is provided on the filter assembly 22, with the end of the handle 221 rotatably mounted on the filter assembly 22.

[0044] When the filter assembly 22 is placed inside the dust cup housing 21, it is supported by the annular retaining ring 214 and can be lifted out by the rotatable handle 221 for easy disassembly and assembly. The filter assembly 22 includes a filter screen frame and a HEPA filter frame from bottom to top. The filter screen and HEPA filter are respectively installed on the filter screen frame and the HEPA filter frame, and the handle 221 is hinged to the HEPA filter frame.

[0045] Preferably, the top surface of the filter assembly 22 is provided with a handle storage groove, and the handle 221 is provided with an arc-shaped bend 2211. The handle 221 is normally stored in the handle storage groove, and when it needs to be removed, the raised arc-shaped bend 2211 facilitates the rotation of the handle 221. Example 3

[0046] This embodiment further improves upon the above embodiment by providing the following technical solution: A dust baffle 231 is provided at one end of the air inlet channel. The dust baffle 231 is arc-shaped, and a first torsion spring 232 is sleeved on the rotating shaft of the dust baffle 231. A guide groove 215 corresponding to the air inlet channel is provided on the inner wall of the dust cup shell 21. The first arm of the first torsion spring 232 contacts the dust baffle 231, and the second arm contacts the air inlet channel. When the dust baffle 231 closes the air inlet channel, it opens under negative pressure suction, and, in conjunction with the guide groove 215, guides the airflow to enter the dust cup tangentially along the inner wall of the dust cup, thereby achieving airflow rotation and improving dust separation efficiency. A rubber baffle 233 is provided on the end face of the air inlet channel, and the shape of the rubber baffle 233 matches the cross-section of the dust baffle 231. The rubber baffle 233 fits into the surface of the dust baffle 231, effectively ensuring the sealing effect of the dust baffle 231. Example 4

[0047] This embodiment further improves upon the above embodiment by providing the following technical solution: A button 42 is provided on the battery pack 4. The button 42 is rotatably mounted on the battery pack housing of the battery pack 4. The locking tongue 421 of the button 42 passes through the top surface of the battery pack housing. A groove 112 corresponding to the locking tongue 421 is provided on the bottom surface of the housing 11. After the locking tongue 421 of the button 42 is inserted into the groove 112, it prevents the battery pack 4 from sliding horizontally and detaching from the housing 11. A spring is provided below the button 42. One end of the spring contacts the back of the button 42, and the other end contacts the battery pack housing. The spring force is used to achieve the self-resetting of the button 42. Example 5

[0048] This embodiment further improves upon the above embodiment by providing the following technical solution: A second notch 113 corresponding to the position of the button 42 is also provided on the housing 11. The housing 11 uses the second notch 113 to position the button 42, thereby further positioning the battery pack 4 and preventing the battery pack 4 of the assembled vacuum cleaner from becoming loose.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
