Description

Technical Field

[0001] This utility model belongs to the field of daily necessities, specifically relating to portable cleaners and cleaning equipment. Background Technology

[0002] Hair dryers, vacuum cleaners, and other cleaning devices are already widely used in daily life, effectively helping users with tasks such as drying and cleaning. With the increasing popularity and intelligence of automobiles, the car interior has become an increasingly important living space. To create a comfortable driving environment, miniaturized and portable cleaners have been introduced. These portable cleaners can be stored inside the car, occupying only a small portion of the space, and can effectively clean both the interior and exterior. For example, a portable blower / vacuum cleaner can vacuum all surfaces inside the car and blow away water, dust, and other dirt from outside, making it particularly effective for cleaning confined spaces.

[0003] Portable cleaners typically have a battery life of 15-40 minutes on a full charge. When the battery is low, a charging cable is needed to connect the cleaner's charging port (input port) to a USB port (output port) in the car. Each USB port connects to a single charging port, and a full charge takes approximately 4 hours. However, users generally cannot wait that long in their car. If portable cleaners used fast charging protocols, not only would production costs increase significantly, but users would also need to purchase additional charging cables that use the same fast charging protocol, which are more expensive, and a separate USB output port in the car, adding to their financial burden. Utility Model Content

[0004] This invention was developed to solve the above-mentioned problems, and aims to provide a portable cleaner and cleaning equipment that is low-cost, simple in structure, and can significantly shorten charging time.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] Portable Cleaner

[0007] This utility model provides a portable cleaner for cleaning dirt from surfaces. It includes a main unit and a battery unit and a charging unit disposed in the main unit. The feature is that it further includes: at least two charging interfaces disposed on the main unit, one end of each charging interface serving as an electrical output terminal and electrically connected to the charging unit, and the other end serving as an electrical input terminal for electrically connecting to an external power source; the at least two charging interfaces are capable of jointly (together / simultaneously) inputting current to the battery unit.

[0008] The beneficial effects of the above scheme are:

[0009] At least two charging ports can input current to the battery cell, which can effectively increase the charging current, shorten the charging time by at least half, and is low in cost, simple in structure, and stable in effect.

[0010] Preferably, in the portable cleaner provided by this utility model, the charging interface is configured such that when the battery unit is charging, each charging interface is connected in parallel with other charging interfaces and together inputs current to the battery unit.

[0011] Preferably, in the portable cleaner provided by this utility model, a heat dissipation hole is provided on the main unit near the charging interface. The heat dissipation hole is connected to the air outlet of the main unit, and the battery unit is arranged in the communication path between the heat dissipation hole and the main unit. In this way, on the one hand, the airflow from the air outlet of the main unit to the heat dissipation hole can dissipate heat and cool down the discharging battery unit. On the other hand, when the battery unit is charging, the heat dissipation hole can also play a role in ventilation and heat dissipation.

[0012] Preferably, in the portable cleaner provided by this utility model, the total airflow area of ​​all heat dissipation holes does not exceed 1 / 10 of the airflow area of ​​the air outlet. For a blower / vacuum cleaner, this structural design can minimize the impact of bypass airflow passing through the heat dissipation holes on the mainstream blowing effect of the nozzle.

[0013] Preferably, in the portable cleaner provided by this utility model, there are multiple heat dissipation holes, which are arranged along one side of the charging interface or around the charging interface, so that heat dissipation is more sufficient and effective.

[0014] Preferably, the portable cleaner provided by this utility model further includes at least one of a blow nozzle for blowing air or a suction nozzle for vacuuming; the blow nozzle is installed at the air outlet of the main unit, and the suction nozzle is installed at the air inlet of the main unit. When both a blow nozzle and a suction nozzle are included, it is a dual-purpose blower and vacuum cleaner.

[0015] Preferably, in the portable cleaner provided by this utility model, the angle between the mouthpiece or suction nozzle and the handle of the main unit is 110° to 130°. This makes it easier for the user to hold and perform blowing and suction operations.

[0016] Preferably, in the portable cleaner provided by this utility model, the dust cup of the suction nozzle has a transparent area that allows the user to observe the dust collection status, making it convenient for the user to empty the dust cup in a timely manner.

[0017] Preferably, in the portable cleaner provided by this utility model, the main unit is equipped with a negative pressure source to generate airflow that is drawn in from the air inlet and flows out from the air outlet. The dust cup of the nozzle is equipped with a filter frame, on which a filter plate with small holes and capable of transmitting negative pressure is formed. The side of the filter frame facing and close to the air inlet is designated as the bottom side, and the side of the filter frame facing and close to the inner wall of the dust cup is designated as the outer side. Filter plates are formed on both the bottom and outer sides. On the outer side, at least a portion of the position opposite to the filter plate has an anti-jamming opening to allow collected dirt to contact the inner wall of the dust cup. This not only increases the filtration capacity of the dust cup but also facilitates the emptying of filtered dirt from the dust cup, preventing dirt from getting stuck on the filter plate. For example, in the filter frame, the filter plate is a semi-circle, and the outer half-circle opposite to the filter plate is an opening.

[0018] Preferably, in the portable cleaner provided by this utility model, a touch screen is installed on the top of the main unit. Positioning the touch screen on the top of the main unit makes it easier for the user to observe and operate the device.

[0019] Portable cleaning equipment

[0020] Furthermore, this utility model also provides a portable cleaning device, which includes the portable cleaner described above in the section on "Portable Cleaner" and at least two charging cables that supply electrical input from an external power source to the portable cleaner. This device has the same beneficial effects as the aforementioned "Portable Cleaner". Attached Figure Description

[0029] The following description, in conjunction with the accompanying drawings, details the specific implementation schemes of the portable cleaner and cleaning equipment involved in this utility model.

[0030] <Example>

[0031] like Figures 1-4 As shown, the portable cleaner 1000 is a dual-purpose blower and vacuum cleaner, capable of cleaning dirt from surfaces by both suction and blowing. The portable cleaner 1000 includes a main unit 10, a battery unit 20, a charging unit 30, a nozzle 40, and a suction nozzle 50.

[0032] The main unit 10 includes a housing 11, a fan 12, a handle 13, and a touch screen 14. The housing 11 is a cylindrical shape with openings at both ends. The fan 12, acting as a negative pressure source, is installed within the housing 11 to generate airflow for both intake and exhaust. The openings at both ends serve as an air inlet 121 (upstream opening) for airflow intake and an air outlet 122 (downstream opening) for airflow exhaust. The handle 13 extends downwards from the bottom of the housing 11 for user grip and is a hollow structure. The touch screen 14 is mounted on the top of the main unit 10 and includes a touch switch display area, a gear display area, and a battery level display area. The touch screen 14 is a common structure in existing technology and will not be described further.

[0033] The battery unit 20 (battery pack) is detachably installed in the handle 13 and connected to the electric fan 12 to supply power to the electric fan 12. In this embodiment, the battery unit 20 includes three 3.7V, 2600mAh cells.

[0034] The charging unit 30 is disposed in the handle 13 and connected to the battery unit 20 for charging the battery unit 20. In this embodiment, as shown... Figure 3 and 6As shown, the charging unit 30 includes two charging ports 31 and a PCB board (circuit protection board) 32. The two charging ports 31 can jointly input current to the battery unit 20. One end of each charging port 31 serves as an output terminal electrically connected to the charging unit 30, and the other end serves as an input terminal for connecting to an external power source. When the battery unit 20 is charging, each charging port 31 is connected in parallel with the other charging ports 31, jointly inputting current to the battery unit 20. In this embodiment, the two Type-C charging ports 31 are soldered onto the PCB board 32 to charge the battery cells, and the battery unit 20 is also mounted on the same PCB board 32. Alternatively, a separate small PCB board can be made, the Type-C charging ports 31 soldered onto it, and then connected to the protection board of the battery unit 20 via wires to charge the battery cells.

[0035] like Figure 6 As shown, the power output terminals of the two charging ports 31 are connected to an external power source (e.g., two USB ports on a car's electrical outlet) via two charging cables 1001. Figure 7 As shown, when the two charging ports 31 are connected to an external power source through two charging cables 1001, switches K1 and K2 are closed, the circuit is turned on, and the two USB plugs 1 and 2 simultaneously input current a to the battery unit 20. The total current I received by the battery unit 20 is 2a, which is twice as large as the charging current a of a single charging port 31. Therefore, the charging time will be shortened by half accordingly.

[0036] like Figure 5 As shown, a heat dissipation hole 111 is provided on the lower side wall of the housing 11 near the charging interface 31. The heat dissipation hole 111 is connected to the handle 13. A bypass hole 112 is provided above the handle 13 near the air outlet 122, penetrating the housing 11. The heat dissipation hole 111 is connected to the air outlet 122 through the handle 13 and the bypass hole 112. Next to the bypass hole 112, there is also a slender through hole 113, which is used to allow a wire (not shown in the figure) to pass through. This wire is used to connect the battery unit 20 and the electric fan 12. The battery unit 20 is located on the communication path between the heat dissipation hole 111 and the main unit 10. The airflow from the bypass hole 112 passes through the battery unit 20 and is discharged to the external environment through the heat dissipation hole 111, forming a bypass airflow, thereby dissipating heat from the battery unit 20. The total airflow area of ​​the heat dissipation hole 111 or all the heat dissipation holes 111 does not exceed 1 / 10 of the airflow area of ​​the air outlet 122. A perforated air vent 123 is provided at the air outlet 122. The air passage area of ​​the air vent 123 is equal to the air passage area of ​​the air outlet 122. In this embodiment, the heat dissipation holes 111 are circular and there are multiple holes, which are arranged in an arc shape and spaced apart along one side of the two charging ports 31.

[0037] The nozzle 40 is used for blowing air and is detachably installed at the air outlet 122 of the main unit 10. The suction nozzle 50 is used for vacuuming and is detachably installed at the air inlet 121 of the main unit 10. The nozzles 40 and 50 can be installed with the main unit 10 in various detachable connection methods such as snap-fit, interlocking, or screw-fit. The angle between the nozzle 40 or the suction nozzle 50 and the handle 13 of the main unit 10 is 110° to 130°.

[0038] like Figure 1 , 4 As shown in Figure 8, the suction nozzle 50 includes a dust cup 51, a filter frame 52, a HEPA filter 53, and a cleanup button 54.

[0039] The dust cup 51 is used for dust collection and has a transparent area 511 that allows the user to observe the dust collection status. In this embodiment, the dust cup 51 is cylindrical, and the cup side wall area of ​​the dust cup 51 corresponding to the filter frame 52 and the HEPA filter 53 is a transparent area 511.

[0040] A filter frame 52 is disposed inside the dust cup 51 and is sealed to the inner wall of the dust cup 51. It is used to pre-filter the dirt sucked in by the suction nozzle 50, filtering large-volume dirt (relative to the HEPA filter 53). A filter plate 521 with small holes and capable of transmitting negative pressure is formed on the filter frame 52. The side of the filter frame 52 facing and close to the air inlet 121 is called the bottom side, and the side of the filter frame 52 facing and close to the inner wall of the dust cup 51 is called the outer side. Filter plates 521 are formed on both the bottom side and the outer side. On the outer side, at least a portion of the position opposite to the filter plate 521 is provided with an anti-jamming opening to allow the collected dirt to contact the inner wall of the dust cup 51. In this embodiment, the filter frame 52 is a forward-opening cylindrical shape, and the filter plate 521 forms a semi-annular half-barrel body with a semi-circular cross-section and an arc length of approximately 1 / 2 of the circumference of the bottom of the barrel; the other half of the barrel body is an anti-jamming opening and does not have a filter plate 521. The dirt intercepted by the filter frame 52 is collected in a columnar cavity formed by the filter plate 521 and the inner wall of the dust cup 51. The cross-sectional area of ​​the cavity is not less than 1 / 2 of the cross-sectional area of ​​the dust cup 51.

[0041] Looking along the direction of the intake airflow, the HEPA filter 53 is located downstream of the filter frame 52 and is used to perform deep filtration of the pre-filtered dirt, filtering out the tiny dirt particles.

[0042] A clearing button 54 is located on the dust cup 51 and is used to open the dust cup 51 from the airflow inlet side to form a pouring spout, thereby emptying the dirt intercepted by the filter frame 52 from the pouring spout into the dust cup 51. When the user presses the button, the inlet side of the dust cup 51 flips downward along the pivot 55, opening the dust cup 51 and forming the pouring spout. The pivot can also be located in other positions, allowing the inlet side of the dust cup 51 to flip in other directions, which will also open the dust cup 51. This clearing button 54 and the opening structure of the dust cup 51 are existing technologies and will not be described in detail further.

[0043] like Figure 3 , 5 As shown in Figure 6, the portable cleaner 1000 and two charging cables 1001 constitute a portable cleaning system. The two charging cables 1001 input power from an external power source to the portable cleaner 1000.

[0044] like Figures 1-8 As shown, based on the above structure, the specific usage of the portable cleaner 10001000 provided in this embodiment is as follows:

[0045] 1. Charging (taking in-vehicle charging as an example)

[0046] The electrical output terminals of the two charging ports 31 are connected to the two USB ports on the vehicle's interior socket via two charging cables 1001. Switches K1 and K2 then close, the circuit is activated, and the two charging ports 31 simultaneously input current 'a' to the battery unit 20, thus quickly charging it. During this process, the heat dissipation vents 111 allow the heat from the battery unit 20 to be released to the external environment.

[0047] 2. Blowing and sucking

[0048] Air blowing cleaning: Install the nozzle 40 at the air outlet 122 of the main unit 10, then aim it at the surface to be cleaned (including crevices), and trigger the electric fan 1212 to start via the touch display screen 1414, thereby blowing away water, dust, hair, dead leaves and other dirt from the surface to be cleaned. Alternatively, if a high air pressure is not required, the nozzle 40 can be omitted when blowing air.

[0049] Suction cleaning: Install the nozzle 50 at the air inlet 121 of the main unit 10, and then aim it at the surface to be cleaned to vacuum. The electric fan 1212 is triggered by the touch display screen 1414 to start, thereby sucking the dirt on the surface to be cleaned into the dust cup 51. Large dirt is pre-filtered and intercepted by the filter frame 52, and then small dirt is filtered and intercepted by the HEPA filter 53. The main stream of clean air after filtration is discharged from the air outlet 122 of the main unit 10. Another small part of clean air flows out from the bypass hole 112 and carries away the heat of the battery unit 20. Then it is discharged to the outside environment from the heat dissipation hole 111, forming a bypass airflow.

[0050] In addition, the nozzle 40 can be used for inflation, such as inflating a swimming ring. The suction nozzle 50 can be used for deflating, such as deflating empty plastic bags or those filled with cotton or clothing to reduce their volume for easier storage.

[0051] 3. Clearance Sale

[0052] Users can observe the dust collection status through the transparent area 511 on the dust cup 51. When the dirt intercepted by the filter frame 52 needs to be removed, the user can press the cleaning button 54. After the button opens, the dust cup 51 opens accordingly to form a pouring port. At this time, the dirt intercepted by the filter frame 52 can be poured out of the dust cup 51 from the pouring port.
