Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly relates to a vacuum mop. Background Art

[0002] Traditional dust mops usually attach a disposable mop cloth to the mop head. The user holds the mop rod and operates the mop head to move on the surface to be cleaned and wipe the surface to be cleaned. Dust such as dirt, hair, and debris on the surface to be cleaned is adhered to the surface of the disposable mop cloth by electrostatic adsorption. However, when the dust mop cleans a surface to be cleaned with a large amount of dust particles, the remaining dust particles are likely to fall off from the surface of the disposable mop cloth, causing secondary pollution of the surface to be cleaned after cleaning. It is necessary to replace the disposable mop cloth and clean again to adsorb the remaining dust particles cleanly. Especially, the cleaning effect on some dust particles with large volume and weight is not very ideal. Therefore, the cleaning ability of the existing dust mops is limited, and there is an urgent need for a vacuum mop with strong dust removal ability and good cleaning effect. Summary of the Invention

[0017] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various structural forms and implementation manners that can be mutually replaced. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0018] An embodiment of the present invention provides a dust-suction mop 100, which includes a mop head 10, a mop rod 20, a suction nozzle 30, a negative pressure source 40, a suction pipeline 50, an air control pipeline 60 and a locking mechanism 70. The structural composition and working principle of the dust-suction mop 100 will be specifically described below according to the accompanying drawings of the specification.

[0019] According to Figure 1As shown, the vacuum mop 100 includes a mop head 10 and a mop rod 20. One end of the mop rod 20 is rotatably connected to the mop head 10. The mop head 10 is adapted to move forward from the back on the surface to be cleaned. The mop head 10 includes a housing 11 and an attachment plate 12 disposed below the housing 11 and configured to be adapted to attach a disposable mop cloth 101. The user can hold the mop rod 20 to operate the mop head 10 so that the mop head 10 moves on the surface to be cleaned and wipes the surface to be cleaned, and dust particles such as dirt, hair, and debris on the surface to be cleaned are adhered to the surface of the disposable mop cloth 101 by electrostatic adsorption.

[0020] To facilitate the mop head 10 to suck the dust particles on the surface to be cleaned in front of the mop head 10 when wiping the surface to be cleaned and improve the cleaning effect of the mop head 10. A suction nozzle 30 is provided on the mop head 10. The suction nozzle 30 extends to the front side position of the mop head 10. The suction nozzle 30 is configured to be adapted to suck the dust-containing air flow on the surface to be cleaned. A negative pressure source 40 is installed on the mop rod 20. The negative pressure source 40 is installed on the mop rod 20 and is in air flow communication with the suction nozzle 30 through a suction pipe 50. The negative pressure source 40 is configured to provide a negative pressure suction force for the outside air to enter the suction nozzle 30. Thus, when the mop head 10 performs a cleaning operation on the surface to be cleaned, it can wipe the surface to be cleaned by electrostatic adsorption while sucking the dust particles on the surface to be cleaned in front of the mop head 10 through the suction nozzle 30.

[0021] According to Figure 2 As shown, to facilitate the installation of the disposable mop cloth 101 onto the mop head 10 and the removal of the disposable mop cloth 101 from the mop head 10, a plurality of installation grooves are provided on the upper surface of the attachment plate 12. A plurality of mop cloth fixing members 123 for fixing the disposable mop cloth 101 are provided on the upper surface of the attachment plate 12. The plurality of mop cloth fixing members 123 are installed at the plurality of installation grooves. The plurality of mop cloth fixing members 123 include a clamping portion, and the clamping portion is adapted to clamp the corners of the disposable mop cloth 101. In this embodiment, the clamping portion is in the structure of a card slot. When installing the disposable mop cloth 101, the corner portion of the disposable mop cloth 101 can be snapped into the card slot for fixation. In other embodiments, the clamping portion can also be a clamping jaw, a clip, etc., and no specific limitation is made.

[0022] According to Figure 1 and Figure 3As shown, when the mop head 10 moves forward from back to front on the surface to be cleaned and cleans the surface to be cleaned, to facilitate the suction nozzle 30 to better suck up the dust particles on the surface to be cleaned in front of the mop head 10, the suction nozzle 30 includes a first extension section 31 facing the front side of the mop head 10, a second extension section 32 connected to the first extension section 31 and extending downward, and a nozzle part 33 connected to the second extension section 32 and having a gradually increasing diameter, and the nozzle part 33 faces the surface to be cleaned. Specifically, the first extension section 31 is a horizontal extension section, and there is a curved transition part between the second extension section 32 and the first extension section 31, which can facilitate the smooth transition between the two extension sections and also enable the nozzle part 33 of the suction nozzle 30 to better fit the surface to be cleaned. In other embodiments, the suction nozzle 30 can also extend linearly and obliquely from one side of the housing 11 at the top of the mop head 10 to the front side position of the attachment plate 12, and the specific form is not limited.

[0023] According to Figure 4 and Figure 5 As shown, to facilitate the dust mop 100 to collect the dust particles on the surface to be cleaned, a receiving chamber 111 for collecting dust particles is constructed inside the housing 11, and a filter 13 for separating dust and air is provided in the receiving chamber 111. In this embodiment, the filter 13 includes a metal filter screen, an air outlet 112 communicating with the receiving chamber 111 in terms of air flow is provided on the housing 11, the suction pipe 50 is communicated with the air outlet 112, and the metal filter screen is installed at the air outlet 112.

[0024] After the vacuum mop 100 has been used for a period of time, to facilitate the dumping of dust from the vacuum mop 100, a dust outlet 121 communicating with the accommodation chamber 111 is provided at the lower part of the attachment plate 12. The dust outlet 121 is configured to be covered and closed by the disposable mop cloth 101 when the disposable mop cloth 101 is attached to the attachment plate 12. In this way, when the vacuum mop 100 moves on the surface to be cleaned and performs the cleaning operation, the dust particles sucked by the suction nozzle 30 can naturally fall on the upper surface of the disposable mop cloth 101 and be supported by the disposable mop cloth 101 after entering the accommodation chamber 111 inside the housing 11 under the action of gravity. When the user dumps the dust particles in the vacuum mop 100, the user only needs to remove the disposable mop cloth 101 and wrap the dust particles, and then throw away the disposable mop cloth 101 wrapped with the dust particles. In other embodiments, a dust bag filter, a filter sponge, a HEPA filter, etc. can also be used to replace the metal filter net. The lower part of the attachment plate 12 may not be provided with a dust outlet 121, and the lower part of the attachment plate 12 may also be a closed structure. An opening may be provided at the upper part of the housing 11, and an upper cover may be installed on the upper part of the housing 11. When the user dumps the dust, the dust bag containing the dust particles can be directly taken out from the opening at the upper part of the housing 11 and thrown away together with the disposable mop cloth 101, and no specific limitation is made.

[0025] To prevent the dust particles sucked by the suction nozzle 30 from directly hitting the metal filter net, causing the metal filter net to be covered with dust particles and blocked, affecting the suction effect, a dust baffle 113 is provided in the accommodation chamber 111 of the housing 11. One end of the dust baffle 113 is connected to the top wall of the accommodation chamber 111 and extends towards the bottom wall side of the accommodation chamber 111. An opening 114 is formed between the dust baffle 113 and the bottom wall of the accommodation chamber 111. The dust particles sucked into the accommodation chamber 111 by the suction nozzle 30 can hit the dust baffle 113 and then fall on the upper surface of the disposable mop cloth 101. The air and part of the dust particles can be separated by the dust baffle 113, and then another part of the dust particles and air can cross the opening 114 and be filtered by the metal filter net. Finally, the air is sucked away by the suction pipe 50. In other embodiments, the dust baffle 113 can also be arranged on the inner bottom wall of the accommodation chamber 111 (i.e., the upper surface of the attachment plate 12). The lower part of the attachment plate 12 may also be a closed structure. An opening may be provided at the upper part of the housing 11. The dust baffle 113 extends from one side of the inner bottom wall of the accommodation chamber 111 towards the inner top wall side of the accommodation chamber 111 and leaves an opening between the dust baffle 113 and the inner top wall of the accommodation chamber 111. In this way, after the dust particles sucked into the accommodation chamber 111 by the suction nozzle 30 hit the dust baffle 113, most of the dust particles can be blocked by the dust baffle 113, and a small part of the dust particles and air can be filtered by the metal filter net after crossing the opening above the dust baffle 113, and no specific limitation is made.

[0026] According toFigure 4 , Figure 6 and Figure 7 As shown in Figure 4 , Figure 6 and Figure 7 , the negative pressure source 40 is installed on the mop rod 20 and is configured to provide a negative pressure air flow that enters the accommodation chamber 111 from the suction nozzle 30. One end of the suction pipe 50 is in air flow communication with the accommodation chamber 111, and the other end of the suction pipe 50 is in air flow communication with the negative pressure source 40. In this embodiment, the negative pressure source 40 includes a manual vacuum pump. The manual vacuum pump includes a pump body 41 with a piston chamber 411 internally, a piston 42 movably fitted in the piston chamber 411, a piston rod 43 connected to the piston 42, and a first one-way valve 44 connected between the piston chamber 411 and the suction pipe 50. The first one-way valve 44 is configured such that when the piston 42 moves upward in the piston chamber 411 and away from the first one-way valve 44, the first one-way valve 44 is in an open state, and when the piston 42 moves downward in the piston chamber 411 and approaches the first one-way valve 44, the first one-way valve 44 is in a closed state. A handle portion 431 for user operation is provided on the piston rod 43. The first one-way valve 44 is a soft rubber plug, and one end of the soft rubber plug is flexibly connected to the connection between the pump body 41 and the suction pipe 50. The soft rubber plug can open and close at the entrance of the piston chamber 411 of the pump body 41 from the suction pipe 50. When the piston 42 is pulled upward and away from the first one-way valve 44, a negative pressure is generated in the piston chamber 411 of the pump body 41, and the pressure difference between the piston chamber 411 and the external environment can force the soft rubber plug to open; when the piston 42 is pulled downward and approaches the first one-way valve 44, a positive pressure is generated in the piston chamber 411 of the pump body 41, and the pressure difference between the piston chamber 411 and the external environment can force the soft rubber plug to block the entrance of the piston chamber 411 of the pump body 41 from the suction pipe 50 again. In other embodiments, the negative pressure source 40 is not limited to the structure of a manual vacuum pump, and the negative pressure source 40 can also be a negative pressure blower, a negative pressure pump, an air compressor, etc., without specific limitation. The first one-way valve 44 can also be the structure of other controllable valves, without specific limitation.

[0027] When the user operates the manual vacuum pump to generate a negative pressure suction force, by operating the handle portion 431 on the piston rod 43 and pulling the piston 42 along the first direction (i.e., upward), the piston 42 is pulled to move upward in the piston chamber 411, a negative pressure is generated in the piston chamber 411, and the pressure difference between the piston chamber 411 and the external environment can force the first one-way valve 44 to open. The dust-containing air flow can be sucked from the suction nozzle 30 into the accommodation chamber 111 of the housing 11 of the mop head 10 under the negative pressure suction of the manual vacuum pump 40. The dust particles are left in the accommodation chamber 111 after being filtered by the filter 13, and the air is sucked into the piston chamber 411 below the piston 42 by the suction pipe 50.

[0028] To facilitate smoother intake and exhaust of the piston chamber 411, a gas control pipeline 60 is connected between the piston chamber 411 and the suction pipeline 50. An air inlet 61 and an air outlet 62 are provided on the gas control pipeline 60, and a first one-way valve 44 is arranged at the air inlet 61. A second one-way valve 63 is arranged at the air outlet 62. The second one-way valve 63 is configured to be in a closed state when the piston 42 moves in the piston chamber 411 and moves away from the first one-way valve 44, and to be in an open state when the piston 42 moves in the piston chamber 411 and moves closer to the first one-way valve 44. In this embodiment, the second one-way valve 63 has the same structure as the first one-way valve 44. In other embodiments, the second one-way valve 63 may also adopt the structure of other controllable valves, which is not specifically limited.

[0029] When the user operates the manual vacuum pump to generate a negative pressure suction force, by operating the handle portion 431 on the piston rod 43 and pulling the piston 42 along the first direction (i.e., upward), the piston 42 is pulled to move upward in the piston chamber 411, a negative pressure is generated in the piston chamber 411, and the pressure difference generated between the piston chamber 411 and the external environment can force the first one-way valve 44 to open at the air inlet 61 and force the second one-way valve 63 to close at the air outlet 62. The dust-containing airflow can be sucked from the suction nozzle 30 into the accommodation chamber 111 of the housing 11 of the mop head 10 under the negative pressure suction of the manual vacuum pump 40. The dust particles are filtered by the filter 13 and remain in the accommodation chamber 111, and the air is sucked into the piston chamber 411 below the piston 42 through the suction pipeline 50.

[0030] To facilitate the air in the piston chamber 411 above the piston 42 to be emptied as soon as possible when the user pulls the piston 42 upward, a plurality of exhaust holes 412 communicating with the airflow in the piston chamber 411 are provided in the upper part of the peripheral side wall of the pump body 41. The plurality of exhaust holes 412 are configured such that when the piston 42 moves upward in the piston chamber 411 and moves away from the first one-way valve 44, the air in the piston chamber 411 above the piston 42 can be discharged to the external environment through the exhaust holes 412. In other embodiments, the exhaust holes 412 may not be provided. When the user pulls the piston 42 along the first direction (i.e., upward), the air in the piston chamber 411 above the piston 42 can be squeezed out through the gap between the piston rod 43 and the pump body 41, which is not specifically limited.

[0031] In order to facilitate the user to operate the manual vacuum pump more labor-savingly, an elastic member 45 is connected between the pump body 41 and the piston 42. The elastic member 45 is constructed such that when the piston 42 moves upward in the piston chamber 411 and away from the first one-way valve 44, the elastic member 45 is in an elastic force release state; when the piston 42 moves downward in the piston chamber 411 and approaches the first one-way valve 44, the elastic member 45 is in an elastic force storage state. In this way, the user only needs to push the piston 42 downward to exhaust the air in the piston chamber 411 and put the elastic member 45 in an elastic force storage state, and then release the piston 42 to realize that the piston 42 is automatically reset under the elastic force of the elastic member 45, thereby completing the negative pressure suction action of the manual vacuum pump. In this embodiment, the elastic member 45 is a spring. In other embodiments, the elastic member 45 can also be other resetting elastic members such as a spring, an elastic diaphragm, a shape memory material, a rubber member, etc., without specific limitation.

[0032] When the air in the piston chamber 411 of the pump body 41 is exhausted, in order to facilitate locking the piston 42 at the bottom of the pump body 41 and close to the first one-way valve 44, so that the user can release the piston 42 when needed to realize the negative pressure suction action of the manual vacuum pump, a locking mechanism 70 is arranged between the pump body 41 and the piston 42. The locking mechanism 70 includes a clamping member 71 movably arranged on the pump body 41, a clamping portion 72 arranged on the upper end of the piston rod 43 and matched with the clamping member 71, and an unlocking member 73 arranged on the pump body 41 and used to drive the clamping member 71 to disengage from the clamping portion 72. The locking mechanism 70 is constructed as follows: when the piston 42 moves to the bottom of the piston chamber 411 and close to the first one-way valve 44, the locking mechanism 70 locks the piston 42 on the pump body 41. In this embodiment, the engaging member 71 is a block movably arranged on the pump body 41, the engaging portion 72 is a slot arranged on the outer peripheral wall of the upper end of the piston rod 43, and the unlocking member 73 is an unlocking button arranged on the pump body 41 and in transmission with the block. Specifically, a sliding groove is arranged on the upper part of the pump body 41, the block is slidably arranged in the sliding groove, and a spring is connected between the unlocking button and the block. When the unlocking button is pressed, the block moves along the sliding groove and disengages from the slot.

[0033] When the piston 42 moves to the lower position of the piston chamber 411, the block on the pump body 41 is inserted into the slot on the piston rod 43, thereby locking the piston 42. The user operates the unlocking button to force the block to disengage from the slot, thereby releasing the locked state of the piston 42. In other embodiments, the engaging member 71 and the engaging portion 72 are not limited to the matching structure of the block and the slot, but may also be mutually engaged teeth or claws, which are not specifically limited.

[0034] according to Figure 8 , Figure 9 and Figure 10As shown, when the user operates the manual vacuum pump to evacuate the air in the piston chamber 411 of the pump body 41, by operating the handle portion 431 on the piston rod 43 and pushing the piston 42 along the second direction (i.e., downward) opposite to the first direction (i.e., upward), a positive pressure is generated in the piston chamber 411. The pressure difference generated between the piston chamber 411 and the external environment can force the first one-way valve 44 to close at the air inlet 61 and force the second one-way valve 63 to open at the exhaust port 62, and the air can be discharged from the exhaust port 62 to the external environment.

[0035] The technical scope of the present invention is not limited to the content in the above specification. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
