As shown in fig. 1, in a preferred embodiment of the present disclosure, the handheld cleaning device includes a main body 100, a lever 200, a base 300, and a dust box assembly 400. Wherein, the operation rod 200 is arranged at the top end of the main machine 100 (the upper end of the main machine 100 in fig. 1) and is used for being held by an operator, so that the operator can control the working posture and the working state of the handheld cleaning device by holding the operation rod 200. The base 300 is disposed at the bottom end of the main body 100 (the lower end of the main body 100 in fig. 1). The dust box assembly 400 is mounted to the chassis 300 and the dust box assembly 400 contacts the floor during operation of the hand-held cleaning appliance for cleaning the floor.

Specifically, the lever 200 is plugged with the host 100. More specifically, a socket (not shown) is disposed at the top end of the host 100, and a card slot (not shown) is disposed on the sidewall of the socket; the bottom end of the operation lever 200 is provided with a catch (not shown in the drawings), and the bottom end of the operation lever 200 is inserted into the socket, and thus the catch is inserted into the card slot, so that the operation lever 200 is fixed with the main body 100.

As shown in fig. 1, the top end of the base 300 is hinged to the bottom end of the main unit 100 so that the base 300 can rotate and swing with respect to the main unit 100, so that the base 300 can rotate in the left-right direction and the front-rear direction with respect to the main unit 100. Preferably, the base 300 can take a dive posture in a state where the hand-held cleaner is lifted, that is, a front end of the base 300 is lower than a rear end of the base 300. Since the technical means for realizing the pivotal connection are conventional in the art, they will not be described in detail herein. Further, the dust box assembly 400 is detachably mounted to the base 300 in a vertical direction (up-down direction shown in the drawing).

As shown in fig. 1, in a preferred embodiment of the present disclosure, the handheld cleaning appliance is further provided with a charging device 500, and the charging device 500 is used for charging a battery of the handheld cleaning appliance.

As shown in fig. 1 and 2, the operating rod 200 includes an extension rod 210, a handle 220, a sheath 230, and an elastic member 240. Wherein the extension pole 210 is inserted into the handle 220. Illustratively, the bottom end of the handle 220 is provided with a socket (not shown in the figure), and the side wall of the socket is provided with a clamping groove (not shown in the figure); the top end of the lever 200 is provided with a catch (not shown in the drawings), and the top end of the lever 200 is inserted into the socket, and thus the catch is inserted into the catch groove, so that the lever 200 and the handle 220 are fixed together.

As shown in fig. 2, a sheath 230 is installed at each end of the extension pole 210. Specifically, a locking groove 211 is formed on a side wall of the extension rod 210, and a locking buckle 231 is formed on an outer circumferential wall of the sheath 230. In the installed state, part of the structure of the sheath 230 is inserted into the extension pole 210, and thus the catch 231 is inserted into the catch groove 211, thereby fixing the sheath 230 to the extension pole 210. Further, it is also possible for those skilled in the art to set the through-hole type catching groove 211 shown in fig. 2 as a sink-type catching groove, that is, set the catching groove 211 as a sink formed on the inner circumferential wall of the extension pole 210, as needed.

As shown in fig. 1, a spray button 221 is provided on the front side of the handle 220, and when the spray button 221 is pressed, the hand-held cleaning device can perform a spraying operation to wet the floor. A dust button 222 is provided at the rear side of the handle 220, and when the dust button 222 is pressed, the hand-held cleaning device can perform a dust suction operation. In addition, the person skilled in the art may also dispose the water spray button 221 and the dust suction button 222 at other arbitrary positions of the handle 220 as needed, for example, both the water spray button 221 and the dust suction button 222 are disposed at the front side or the rear side of the handle 220. In addition, the skilled person can replace the water spray button 221 and the dust collection button 222 with any other feasible operation keys, such as a touch operation key, as required.

With continued reference to fig. 2, the handheld cleaning apparatus further includes an electrical lead 600 disposed in the extension pole 210, the electrical lead 600 including a stop member 610 and a redundant segment 620. Wherein, two end sides of the redundant segment 620 are respectively provided with a limiting member 610. The upper end of electrical lead 600 in fig. 2 is fixedly attached to handle 220 after passing through hole 232 in upper sheath 230, and the lower end of electrical lead 600 in fig. 2 is fixedly attached to host 100 after passing through hole 232 in lower sheath 230.

With continued reference to fig. 2, the two ends of the elastic member 240 are respectively connected to the two position-limiting members 610, and the elastic member 240 is used for providing a force to the two position-limiting members 610 to approach each other. Illustratively, the elastic member 240 may be a rubber band or a spring. Further, in order to prevent the elastic member 240 from being exposed from the extension rod 210, the size of the elastic member 240 is larger than that of the through hole 232.

The following will specifically describe the detachment and connection between the extension pole 210 and the handle 220 and the main unit 100 with reference to fig. 1 and 2.

As shown in fig. 1, in an assembled state, the top end of the extension pole 210 is inserted into the handle 220, and the bottom end of the extension pole 210 is inserted into the main unit 100. One end of electrical lead 600 is fixedly connected to host 100 and the other end of electrical lead 600 is fixedly connected to handle 220, and electrical lead 600 is capable of pulling handle 220 and host 100 together under the force of resilient member 240 to provide a force that approaches each other.

After the extension pole 210 is pulled out from the main body 100, the elastic member 240 and the redundant segment 620 of the electrical lead 600 are elongated, and the extension pole 210 and the main body 100 are flexibly connected together through the electrical lead 600. Also, when the extension pole 210 is plugged with the main unit 100, the elastic force generated by the elastic member 240 assists the user to bring the extension pole 210 and the main unit 100 close to each other and plug them together. Similarly, when the handle 220 is pulled out of the extension pole 210, the resilient member 240 and the redundant segment 620 of electrical leads 600 are stretched and the extension pole 210 and the handle 220 are flexibly connected together via the electrical leads 600. Also, when the extension pole 210 and the handle 220 are plugged together, the elastic force generated by the elastic member 240 assists the user to bring the extension pole 210 and the handle 220 close to each other and plug together.

It can be seen that the elastic member 240 can function as a wire take-up, i.e., can bring both ends of the electrical lead 600 close to each other. Therefore, the elastic member 240 may be replaced with any other possible wire rewinding device, such as an automatic wire rewinding device having a coil spring, on the premise that both ends of the electrical lead 600 can be brought close to each other and the wire rewinding function can be performed.

As shown in fig. 3a, the front side of the main body 100 is provided with a spray opening 101, and when a spray button 221 on the handle 220 is pressed, the spray opening 101 sprays liquid to the front side of the main body 100.

As shown in fig. 3a and 3b, the main body 100 includes a main body structure 110, a liquid storage box 120 mounted on the main body structure 110, an electrical connection fixing plate 130, an electrical connection pin assembly 140, a first conductive sheet 150, a second conductive sheet 160, a battery (not shown), a dust suction motor (not shown), a dust suction fan (not shown), a water pump motor (not shown), a water pump (not shown) as a transfer pump, and a control board (not shown). The first conductive sheet 150 and the second conductive sheet 160 are electrically connected to the electrical connection pin assembly 140; the electrical connection pin assembly 140 is electrically connected with the battery; the battery is respectively electrically connected with the dust collection motor and the water pump motor, the working state of the water pump motor is controlled by the water spraying button 221, and the working state of the dust collection fan is controlled by the dust collection button 222; the dust collection motor is in driving connection with the dust collection fan; the water pump motor is in driving connection with the water pump; the water pump is communicated with the liquid storage box 120 through a water pipe, and the water pump is also communicated with the spraying port 101 through a water pipe.

With continued reference to fig. 3a and 3b, the body structure 110 includes an inner support 111, a front shell 112, and a rear shell 113 fixedly coupled together. Illustratively, the front shell 112 is provided with a threaded hole column, the inner bracket 111 is provided with a through hole, the rear shell 113 is provided with a through hole, and a screw is screwed with the threaded hole column on the front shell 112 after passing through the through holes on the rear shell 113 and the inner bracket 111, so as to fixedly connect the inner bracket 111, the front shell 112 and the rear shell 113 together.

With continued reference to fig. 3a and 3b, the front side of the internal bracket 111 is provided with a control board mounting cavity 1111, and the control board mounting cavity 1111 is used for mounting a control board and a battery. A suction fan installation cavity 1112 is formed at the bottom of the inner bracket 111, and the suction fan installation cavity 1112 is used for installing a suction motor and a suction fan. The rear side of the inner bracket 111 is provided with a water pump motor mounting cavity 1113, and the water pump motor mounting cavity 1113 is used for mounting at least one part of a water pump motor and a water pump.

From the structure shown in fig. 1, 3a and 3b, it can be seen or unambiguously concluded by those skilled in the art that the axis of the suction fan is arranged eccentrically to the axis of the operating lever 200 (in particular the extension lever 210), and that the operating lever 200 is arranged on the front side of the suction fan. So that the front surface of the main body 100 is as close as possible to the front surface of the operation lever 200, thereby allowing the user to obtain a better view when looking forward from the place of the handle 220. Meanwhile, the gravity center of the whole host 100 is further back, the gravity applied to the user by the handle 220 is increased, and the holding hand feeling of the user is optimized.

With continued reference to fig. 3a and 3b, the front housing 112 is provided with a vent 1121 and a shower opening 101. The ventilation hole 1121 is used to discharge the air sucked by the dust suction fan to the outside again.

Further, although not shown, it will be understood by those skilled in the art that in the assembled state, the front housing 112 and the rear housing 113 can enclose a heat dissipation chamber in which the control board, the battery, the dust suction motor, the dust suction fan, the water pump motor and the water pump are located, and the heat dissipation chamber is in communication with the ventilation opening 1121. Furthermore, in order to increase the heat dissipation speed of the dust collection motor, first heat dissipation holes are formed in the circumferential wall and/or the top wall and/or the bottom wall of the dust collection motor, and the first heat dissipation holes are communicated with the heat dissipation cavity. Similarly, in order to increase the heat dissipation speed of the water pump motor, the circumferential wall and/or the top wall and/or the bottom wall of the water pump motor are/is provided with second heat dissipation holes, so that heat in the water pump motor can be quickly transferred to the outer side (namely, a heat dissipation cavity) of the water pump motor through the second heat dissipation holes, namely, the second heat dissipation holes are communicated with the heat dissipation cavity.

As shown in fig. 3a and 3b, the reservoir 120 is fixed between the inner holder 111 and the rear case 113.

As shown in fig. 4a to 4c, the reservoir 120 includes a case 121 and a cover 122 pivotally connected. The case 121 is provided with a liquid injection port 1211, a liquid storage chamber 1212, and a liquid injection channel 1213 connecting the liquid injection port 1211 and the liquid storage chamber 1212. The liquid injection channel 1213 extends into the liquid storage cavity 1212, so that an annular cavity 1214 is formed between the side wall of the liquid injection channel 1213 and the side wall of the liquid storage cavity 1212, the annular cavity 1214 is formed with an inlet/outlet 12141 at an end far from the liquid injection port 1211, and the inlet/outlet 12141 can be closed by the liquid level of the liquid in the liquid storage cavity 1212. As will be appreciated by those skilled in the art, when the liquid inlet 1211 of the liquid storage box 120 faces upward, the liquid level in the liquid storage cavity 1212 submerges the inlet/outlet 12141, so as to close the annular cavity 1214 and allow a portion of air to be present in the annular cavity 1214.

Furthermore, the annular cavity 1214 may be configured as any other feasible cavity, such as a C-shaped or U-shaped cavity in cross-section, as desired by one skilled in the art.

Preferably, the volume of the annular cavity 1214 is larger than the volume of the liquid injection channel 1213, so that during the process of injecting liquid into the cartridge 120 (during which the cartridge 120 is vertical or nearly vertical and the injection port 1211 of the cartridge 120 is facing upward), liquid overflowing from the reservoir 1212 into the liquid injection channel 1213 can flow completely into the annular cavity 1214 when the cartridge 120 is tilted. At the same time, the cap 122 can also be closed by squeezing the liquid in the injection channel 1213 during closure of the cap 122, such that the liquid compresses the air in the annular cavity 1214 and thus enters the annular cavity 1214.

As can be seen from fig. 4b and 4c, the diameter of the liquid injection channel 1213 gradually increases from the inside to the outside to facilitate the user to fill the liquid storage case 120 with water. Preferably, the injection channel 1213 is of a tapered configuration, and the taper of the front portion of the injection channel 1213 is less than the taper of the rear portion, so that the bottom end of the injection channel 1213 faces the front side of the injection channel 1213, thereby allowing the rear portion of the annular cavity 1214 to have more space and to accommodate more liquid when the cartridge 120 is tilted backwards.

With continued reference to fig. 4 a-4 c, the cover 122 is configured to enclose the reservoir 1212. Specifically, the cap 122, after being closed, is capable of closing the reservoir 1212 by closing the fluid injection channel 1213. Alternatively, one skilled in the art may close the liquid storage chamber 1212 by closing the liquid injection port 1211 after the lid 122 is closed, if necessary.

As shown in fig. 4a to 4c, the case 121 is provided with a sink 1215, and the cover 122 is provided with a rotation shaft 1221. The rotation shaft 1221 is inserted into the sinking groove 1215 and can rotate in the sinking groove 1215. In the mounted state, the rear case 113 covers the sinking groove 1215, thereby preventing the rotation shaft 1221 from being detached from the sinking groove 1215, so that the cover 122 and the case 121 are pivotally coupled together.

As shown in fig. 4a, the bottom of the case 121 is provided with a recessed receiving groove 1216, and the receiving groove 1216 can receive a water pump motor. In other words, at least a portion of the water pump motor is mounted in the receiving groove 1216, so that the sidewall of the receiving groove 1216 abuts against the circumferential surface of the water pump motor, thereby allowing heat generated by the water pump motor to be transferred to the tank 121 and absorbed by the liquid in the tank 121, thereby achieving the effect of cooling the water pump motor.

In addition, in the case that the liquid in the box 121 can absorb heat of the water pump motor, the person skilled in the art can also set the receiving groove 1216 at any other feasible position on the box 121, such as the left side, the right side or the middle position of the box 121, as required. Further, the receiving groove 1216 may be provided in any feasible shape, such as a U-shaped, circular, semi-circular, or C-shaped cavity, as desired by those skilled in the art.

Based on the above description of "the water pump motor is located in the heat dissipation chamber" and "the side wall of the holding groove 1216 abuts against the circumferential surface of the water pump motor", it can be seen that the side wall of the holding groove 1216 constitutes a part of the chamber wall of the heat dissipation chamber, in other words, a part of the chamber wall of the heat dissipation chamber is constituted by the side wall of the case body 121.

As shown in fig. 4a to 4c, the cover 122 is provided with a sealing ring 1222, and the cover 122 can be inserted into the liquid injection channel 1213, so that the sealing ring 1222 abuts against the side wall of the liquid injection channel 1213 to close the liquid storage cavity 1212. It will be appreciated by those skilled in the art that the sealing ring 1222 can be compressively deformed so that the sealing ring 1222 can first abut the sidewall of the fill channel 1212 and then slide a distance over the sidewall of the fill channel 1222 (during which the sealing ring 1222 is gradually shrunk radially inward) to close the cover 122 in place.

Further, in order to ensure the reliability of the cap 122 for sealing the filling channel 1212, a plurality of sealing rings 1222 are disposed on the cap 122. Preferably, the plurality of sealing rings 1222 are sequentially reduced in diameter along a direction of insertion into the injection channel 1212.

Alternatively, the electrical connection fixing plate 130 and the rear case 113 may be fixedly connected together by any feasible means, such as clamping, bonding, riveting, screwing, ultrasonic welding, and the like.

As shown in fig. 5a and 5b, the electrical connection fixing plate 130 is fixed with two electrical connection pin assemblies 140, a first conductive sheet 150 and a second conductive sheet 160. Specifically, one of the two electrical connection pin assemblies 140 is a positive electrode, and the other is a negative electrode. Alternatively, the two electrical connection pin assemblies 140 are positive and negative with respect to each other (i.e., when one electrical connection pin assembly 140 is positive, the other electrical connection pin assembly 140 is negative). And one of the two electrical connection pin assemblies 140 is fixedly connected to the first conductive plate 150 and the other of the two electrical connection pin assemblies 140 is fixedly connected to the second conductive plate 160.

With continued reference to fig. 5a and 5b, since the two electrical connection pin assemblies 140 are identical in structure, only one electrical connection pin assembly 140 will be described in detail herein.

Specifically, the electrical connection pin assembly 140 includes a pin 141 shown in fig. 5a and 5b and a fixing clip 142 shown in fig. 6a to 6 b. Among them, the pin 141 includes a power supply part 1411 connected with the fixing clip 142 and a power receiving part 1412 connected with the first conductive sheet 150 or the second conductive sheet 160.

As shown in fig. 5a, the power supply portion 1411 is provided with an annular groove 14111 on a peripheral wall thereof. The pin 141 is connected to the fixing clip 142 through the annular groove 14111, and a person skilled in the art can arrange the annular groove 14111 into any other feasible groove, such as a symmetrical two-sided sunken groove, as required, provided that the pin 141 can be connected to the fixing clip 142.

As shown in fig. 5b, the power receiving portion 1412 is fixedly connected to the first conductive sheet 150 or the second conductive sheet 160, and an end of the power receiving portion 1412 remote from the power supply portion 1411 is raised outward and forms a bump, so that the power receiving portion 1412 can better contact with the charging head 510 through the raised bump. In addition, those skilled in the art may also form raised bumps on the first conductive sheet 150 or the second conductive sheet 160 as needed so that the end of the power receiving portion 1412 remote from the power supply portion 1411 does not exceed the outer surface of the first conductive sheet 150 or the second conductive sheet 160.

As shown in fig. 6a and 6b, the fixing clip 142 includes a clamping portion 1421 and a wire connecting portion 1422, the clamping portion 1421 clasps the power supply portion 1411 of the pin 141, and at least a part of the structure of the clamping portion 1421 is inserted into the annular groove 14111 to limit the relative axial displacement between the fixing clip 142 and the pin 141. Specifically, at least a part of the structure of the grip 1421 is a protrusion 14211 formed inside the grip 1421. Further preferably, the protrusion 14211 is stamped from the outside to the inside by a stamping process. In addition, one skilled in the art may also configure at least a portion of the structure of the clamping portion 1421 to be a flanging structure of the clamping portion 1421 as required.

Those skilled in the art will appreciate that to increase the contact area between the gripping portion 1421 and the pin 141 and reduce the electrical resistance, the axial width of the gripping portion 1421 is greater than the axial width of the annular groove 14111 on the pin 141.

Although not shown in the drawings, the wire connecting part 1422 is fixedly connected to a wire, and one end of the wire remote from the wire connecting part 1422 is connected to the battery.

With reference to fig. 6a and 6b, the fixing clip 142 further includes an abutting portion 1423 fixedly connected to or integrally formed with the clamping portion 1421, and the abutting portion 1423 can abut against an end of the power supply portion 1411 far from the power receiving portion 1412, so as to increase a contact area between the fixing clip 142 and the pin 141 and ensure reliability of connection between the fixing clip 142 and the pin 141.

Returning to fig. 5b, the first conductive sheet 150 has a circular sheet-like structure, and the second conductive sheet 160 has an annular sheet-like structure.

Further, although not shown in the drawings, a magnet or a magnetic member is further disposed on the electrical connection fixing plate 130, so that the electrical connection fixing plate 130 can be attracted to the charging plug 510 shown in fig. 7 by the magnet or the magnetic member, thereby electrically connecting the first and second conductive plates 150 and 160 (or the pins 141) to the charging plug 510.

As shown in fig. 7, the charging device 500 includes a charging plug 510 electrically connected to the host 100, and a magnet or a magnetic member is disposed on the charging plug 510 so that the charging plug 510 can be attracted to the host 100 by magnetic force. Further, the positive and negative output terminals of the charging plug 510 may have any feasible structure. For example, a circular sheet-like structure and an annular sheet-like structure are shown in fig. 7. Alternatively, the aforementioned electrical connection pin assembly 140, the first conductive sheet 150, and the second conductive sheet 160 may be disposed on the charging plug 510 as needed by those skilled in the art.

As shown in fig. 8a and 8b, the base 300 includes an upper base case 310, a lower base case 320, and a catching device 300. The upper bottom case 310 and the lower bottom case 320 are fixedly connected together by any feasible means such as clamping, screw connection, ultrasonic welding, etc. The engaging device 300 is disposed on the lower case 320, or one skilled in the art can dispose the engaging device 300 on the upper case 310, or between the upper case 310 and the lower case 320, as required.

With continued reference to fig. 8a and 8b, the exposed portions of the upper surfaces of the upper base 310 and the lower base 320 are provided as arc-shaped surfaces, especially the front portions of the upper base 310 and the lower base 320. Further, the front end of the lower bottom housing 320 is provided with a downwardly protruding limiting structure 321, and the limiting structure 321 can guide the liquid on the upper surfaces of the upper bottom housing 310 and the lower bottom housing 320 to the groove 4111 (as shown in fig. 9 c) in the dust box assembly 400.

As can be seen from fig. 8a and 8b, two limiting structures 321 are disposed on the left and right sides of the lower case 320. Preferably, the limiting structure 321 can abut against the side wall of the groove 4111 (shown in fig. 9 c), so that the limiting structure 321 can limit the movement of the dust box assembly 400 relative to the lower case 320. Preferably, the limiting structure 321 is a plate-shaped structure extending along the left-right direction of the base, and the left and right sides of the limiting structure 321 are inclined surfaces capable of guiding the limiting structure 321 to be inserted into the groove 4111 (as shown in fig. 9 c).

As shown in fig. 8b, the engaging means 330 includes a first jaw 331 disposed on the left side of the base 300 and a second jaw 332 disposed on the right side of the base 300. The first and second claws 331 and 332 can secure the dust box assembly 400 to the chassis 300 by clasping.

Specifically, the first jaw 331 is pivotally connected to the lower base 320, and a first returning member for rotating and holding the first jaw 331 from the unlocking position to the locking position is provided between the first jaw 331 and the lower base 320. The second jaw 332 is pivotally connected to the lower base housing 320, and a second returning member for rotating and holding the second jaw 332 from the unlocking position to the locking position is provided between the second jaw 332 and the lower base housing 320. Wherein the first and second return members are both torsion springs. Alternatively, the first return member and/or the second return member may be any other elastic member such as a tension spring, a compression spring, etc. as required by those skilled in the art.

As can be seen in fig. 8b, the first and second pawls 331, 332 are rotatable to an unlocked position when rotated away from the dust bin assembly 400; the first and second pawls 331 and 332 are rotatable to a locking position when rotated in a direction approaching the dust box assembly 400.

As shown in fig. 8a, in the locked position, the first and second claws 331 and 332 respectively hook the circumferential edge of the dust box assembly 400, in particular, the circumferential edge of the box body 410 (shown in fig. 9 a) of the dust box assembly 400.

As shown in fig. 8b, in order to facilitate the user to detach the dust box assembly 400 from the base 300, the first claws 331 are provided with pressing portions 3311, and the pressing portions 311 are exposed on the upper surface of the base 300. When the pressing part 3311 is pressed, the first jaw 331 is moved from the locking position to the unlocking position, so that the left end of the dust box assembly 400 drops down by its own weight, and then the right end of the dust box assembly 400 is separated from the second jaw 332, so that the dust box assembly 400 is separated from the base 300.

Although not shown in the drawings, it will be understood by those skilled in the art that a mounting cavity may also be provided on the base 300 (and particularly the lower housing 320) and enable the mounting cavity to receive a portion of the top of the dust box assembly 400.

As shown in fig. 9a to 9c, the dust box assembly 400 includes a box body 410, a floor-mopping member 420, a filter mesh 430, and a check valve 440. Wherein, the floor-mopping component 420 is arranged at the bottom end of the box body 410, the filter screen 430 is arranged at the top end of the box body 410, and the one-way valve 440 is arranged at the inner side of the box body 410.

As shown in fig. 9c to 9f, a sinking structure 411 is disposed at the front end of the box 410, and a groove 4111 with an upward opening is formed on the sinking structure 411. The groove 4111 can accommodate the limiting structure 321 on the base 300, and thus can receive the liquid guided by the limiting structure 321 from the base 300. Preferably, the groove 4111 is a bar-shaped groove extending in the left and right direction of the case 410. Alternatively, both left and right ends in the left-right direction of the groove 4111 are provided with inclined surfaces for guiding the insertion of the stopper 321 into the groove 4111. Further, a plurality of air inlets 4112 are disposed on the sinking structure 411, and each air inlet 4112 penetrates through the sinking structure 411 along the front-back direction of the sinking structure 411.

With reference to fig. 9c to 9f, the box 410 is further provided with a dust collecting chamber 412, a dust suction port 413 and an air outlet (not labeled). Wherein the dust suction port 413 is formed at the front end of the dust collection chamber 412, and the dust suction port 413 is located at the rear side of the sinking structure 411, in other words, the dust suction port 413 is located between the dust collection chamber 412 and the groove 4111. The air outlet is formed at the top end of the dust collecting chamber 412 and covered by the filter screen 430. In the installed state, the dust collecting chamber 412 is communicated with the air inlet of the dust suction fan through the air outlet.

With continued reference to fig. 9 c-9 f, a lateral groove 414 is formed between the front sidewall of the dust collecting chamber 412 and the rear sidewall of the groove 4111, and the lateral groove 414 is used for guiding air into the dust suction port 413. In other words, the sinking structure 411 constitutes a front side wall of the lateral groove 414, and a plurality of openings (i.e., the air inlets 4112) are provided on the front side wall. Further, as can be seen from the figure, the dust suction port 413 is aligned with one of the plurality of air inlet ports 4112, and both ends of the lateral groove 414 are open ends.

It can be understood by those skilled in the art that, compared to the situation that the external air enters the dust suction port 413 from any direction, the external air can only enter the dust suction port 413 through the plurality of air inlets 4112 and the two open ends of the lateral grooves 414, which increases the flow rate of the air, and the fast flowing air can more easily carry the foreign matters (dust) to the dust suction port 413 and then enter the dust collection chamber 412.

With continued reference to fig. 9c to 9f, the interior of the case 410 is provided with a slope 415 aligned with the dust suction port 413, and the slope 415 is matched with the movable portion 442 of the check valve 440, so as to close the dust suction port 413. Preferably, the ramp 415 is configured to be U-shaped as shown in fig. 9 c. Of course, the bevel 415 can be provided in any other feasible shape, such as an O-shape, a C-shape, an arc shape, etc., as desired by one skilled in the art.

As shown in fig. 9a to 9e, the filter screen 430 is disposed at the top end of the case 410 and is fixedly connected to the case 410. The fixing connection mode can be bonding, ultrasonic welding, screw connection and the like.

As shown in fig. 9c to 9e, the check valve 440 is bent to form a fixed portion 441 and a movable portion 442. The fixing portion 441 is fixedly coupled to the filter 430, and thus fixedly coupled to the case 410. The movable portion 442 is movable to a first position and a second position. The movable portion 442 fits together with the inclined surface 415 in the case 410 in the first position, and thus closes the dust suction port 413; the movable portion 442 is separated from the inclined surface 415 in the case 410 in the second position, and thus opens the dust suction port 413.

Preferably, the check valve 440 is a V-shaped sheet structure made of plastic, metal foil, or any other material having elasticity. So that the movable portion 442 can be rotated from the second position to and maintained at the first position by the resilient force of the check valve 440 itself and thus close the suction opening 413. It is further preferable that the resilient force is smaller than the negative pressure applied to the movable portion 442 when the dust suction fan is operated, so that the pressure difference between the inside and the outside of the movable portion 442 can open the movable portion 442 and thus the dust suction port 413 when the dust suction fan is operated.

As can be seen from fig. 9c to 9e, the area of the movable portion 442 is larger than that of the fixing portion 441, so that the movable portion 442 can cover not only the fixing portion 441 but also a partial area of the filter 430 when the movable portion 442 is attached to the filter 430.

It will be appreciated by those skilled in the art that during operation of the suction fan, the negative pressure generated by the suction fan drives air from the suction opening 413 into the dirt collection chamber 412 and then through the filter screen 430 to the suction fan. In this process, when the air flowing to the filter 430 flows to the movable portion 442, a force is applied to the lower surface of the movable portion 442, so as to push the movable portion 442 to rotate to a position where the movable portion 442 is attached to the lower surface of the filter 430. In other words, during the operation of the dust suction fan, the air pressure difference is generated between the upper and lower sides of the movable portion 442 due to the flow of air, and the air pressure difference drives the movable portion 442 to rotate to a position where the movable portion 442 is attached to the lower surface of the filter screen 430.

It will be understood by those skilled in the art that the movable portion 442 provides an impact force to the filter screen 430 at a moment of contact with the filter screen 430, and the impact force may vibrate the filter screen 430 to shake off a portion of foreign objects (e.g., dust, hair, etc.) attached to the filter screen 430.

Further, those skilled in the art can understand that, with the use of the handheld vacuum cleaner, more and more dust can be attached to the filter screen 430, which causes the partial filter holes on the filter screen 430 to be blocked, which causes the filter screen 430 to obstruct the flow of air, thereby reducing the flow rate of air, further reducing the pressure difference between the upper side and the lower side of the movable portion 442, which causes the movable portion 442 to be unable to be attached to the filter screen 430 under the action of the pressure difference, and forming a gap capable of accommodating the foreign matter between the movable portion 442 and the filter screen 430.

That is, the movable portion 442 of the check valve 440 can be attached to the filter 430 when the filter 430 is relatively clean, and cannot be attached to the filter 430 when the filter 430 is relatively dirty.

As can be seen from fig. 9c to 9e, the included angle between the movable portion 442 and the fixed portion 441 in the first position is smaller than 90 °, and preferably smaller than 60 °, so that a portion of foreign matters (e.g. dust) can be carried above the movable portion 442 when the movable portion 442 is in any position, and thus when the dust suction fan stops working, the gravity of the portion of foreign matters can provide a vertically downward pressure to the movable portion 442, so that the movable portion 442 is forced to rotate from the second position to the first position, and the dust suction port 413 is closed.

As shown in fig. 9f, the outer side of the bottom wall of the box body 410 is provided with a plurality of longitudinal grooves 416, a U-shaped groove 417 and the aforementioned transverse grooves 416. The longitudinal grooves 416 are parallel to the front and rear direction of the case 410 during operation, the front ends of the longitudinal grooves 416 are closed ends, the rear ends of the longitudinal grooves 416 are open ends, and the longitudinal grooves 416 are distributed at equal intervals along the left and right direction of the case 410 during operation. In addition, the plurality of longitudinal grooves 416 may be distributed at unequal intervals as desired by those skilled in the art. The U-shaped groove 417 is disposed around the suction opening 413, or the U-shaped groove 417 may be disposed as any other feasible groove, such as a C-shaped groove, an arc-shaped groove, etc., according to the actual needs of those skilled in the art.

As shown in fig. 9a and 9b, the floor member 420 covers all of the longitudinal grooves 416 and the U-shaped grooves, and the front end of the floor member 420 extends into the lateral grooves 414 and the front end of the floor member 420 extends to the rear side of the case 410.

As can be understood by those skilled in the art, by providing a plurality of grooves (including the longitudinal groove 416 and the U-shaped groove 417) on the bottom wall of the box 410, the pressure on the part of the floor mopping member 420 corresponding to the grooves is smaller, so that more moisture can be absorbed, and the situation that the floor mopping member 420 cannot be completely absorbed when the moisture on the ground is more can be avoided. Meanwhile, when the part of the mopping member 420 not corresponding to the groove lacks less moisture, the part corresponding to the groove can slowly release the part, so that the moisture endurance on the mopping member 420 is longer, the operation of pressing the water spraying button 221 for many times by a user is avoided, and the use experience of the user is improved.

It can also be understood by those skilled in the art that when there is a tiny protrusion on the ground, the protrusion can be wrapped by the portion of the mopping member 420 corresponding to the groove, so that the mopping member 420 can clean the side and the root of the protrusion, thereby ensuring the cleanness of the ground.

It can also be understood by those skilled in the art that the front end of the mopping member 420 can be sucked by the negative pressure generated by the dust suction fan when the dust suction fan operates by extending the front end of the mopping member 420 into the transverse groove 414, so that the front end of the mopping member 420 is tilted upwards, thereby preventing the front end of the mopping member 420 from being damaged due to the protrusion on the floor hooking the front end of the mopping member 420.

It will also be appreciated by those skilled in the art that any feasible member may be used, such as a sponge, cotton cloth, cloth strip, etc.

As can be seen from the foregoing description, the dust box assembly 400 is detachable from the base 300, and when the handheld cleaning apparatus is lifted in the vertical direction, the base 300 can assume the dive posture, so that the bottom cases (310 and 320) also assume the dive posture, thereby enabling the limiting structure 321 to be located at the lowest end of the base 300.

Further, in mounting the dust bin assembly 400 and the chassis 300 together: the dust box assembly 400 is first placed on the floor, the hand-held cleaning device is then lifted and the base 300 is aligned with the dust box assembly 400, and the base 300 is then gradually moved toward the dust box assembly 400. As the chassis 300 approaches the dust box assembly 400, the stopper 321 is first brought into contact with the dust box assembly 400 and inserted into the groove 4111 of the case body 410, thereby guiding the installation of the chassis 300 and the dust box assembly 400. Subsequently, the housing 410 of the dust box assembly 400 abuts the first and second pawls 331 and 332, and then the first and second pawls 331 and 332 are rotated from the locked position to the unlocked position, and then the first and second pawls 331 and 332 are automatically restored and maintained in the locked position by the respective restoring members, and thus the dust box assembly 400 is locked to the base 300.

Of course, the user may also mount and secure the dust bin assembly 400 to the base by grasping the dust bin assembly 400 and actively moving the dust bin assembly 400 in a direction toward the base 300.

Of course, the user may also mount and secure the dust bin assembly 400 to the base by grasping the dust bin assembly 400 and actively moving the dust bin assembly 400 in a direction toward the base 300.
